Description of the invention: [Technical field to which the invention belongs] The present invention relates to a rubber tire recycling machine, and particularly to a rubber powder screening machine. 5 [Previous technology] After the recycling of waste tires in the past, because it contains a large amount of impurities such as metal wires and cotton wool, it must be screened for impurities before it can be used in the recycling production process after screening. The screening operation 10 first chops the discarded tires into pieces, then uses a rubber crusher and a magnetic separator to remove the rubber particles containing metal wires, and then sends them to a machine with a vibration system. The rubber powder of the metal wire shakes to promote the separation of the cotton wool from the rubber powder. At the same time, with a dust collection device located above the machine, the cotton wool is extracted from the rubber powder by suction, and the waste is screened and recovered by 15 Purpose of batting. However, it is difficult for the recycled waste mixed with cotton powder and rubber powder to be completely sucked by the dust collecting device during the lifting process, so the recycled waste after screening has a high cotton content, which makes it recyclable. The range of conversion is extremely narrow. Therefore, it has low environmental protection value and is mostly used as recycled products such as PU runway 20 paving materials, which is not highly applicable. [Summary of the Invention] The main purpose of the present invention is to provide a rubber powder sorter, which can effectively remove cotton batts from rubber powder recycling waste. In order to achieve the purpose of the disclosure, the rubber powder screening machine provided by the present invention is used for separating and recovering the recovered waste mixed with cotton wool and rubber powder. The rubber powder screening machine includes: a machine; a conveying device; 5 is set on the machine, which includes at least one stepped conveying area, which is used to convey the recovered waste; a blower device is provided in the conveying section, and the blower device can be directed toward the conveying area The recovered waste material in the falling process sprays airflow, and the cotton wool therein is blown from the rubber powder; and a dust collecting device includes at least one wind bucket disposed above the conveying area, and the 10 wind Buckets are capable of sucking cotton wool from such recycled waste. [Embodiment] The reason is that, in order to make the reviewers better understand the components and composition of the present invention, the following examples are listed together with the illustrations as follows: 15 The first diagram is the first preferred embodiment of the present invention A perspective view; a second view is a schematic view of the use of the first preferred embodiment of the present invention; and a third view is a schematic view of the second preferred embodiment of the present invention. 20 Referring to the first and second figures, a rubber powder screening machine 1 according to the first preferred embodiment of the present invention is used to separate and recover the recovered waste mixed with the rubber powder a and the cotton wool b; the rubber powder screening The machine 1 mainly includes: a machine 10, a conveying device 20, a blowing device 30, and a set of 1235102 dust device 40, of which; the remote machine 10 is composed of two opposite side plates 11, and one connecting the two side plates 11 is the same The back plate 12 on the side edge and the brackets 13 which are quartered on the two side plates 11 are combined together, and after the composition, a space 14 is formed within the machine 10. 5 10 15 The conveying device 20 includes a plurality of first and second rollers 21 (22) pivoted on the two side plates 11 at both ends, and a first and second rollers 21 (22) 22) between the endless conveyor belt 23, and the first and second rollers 21 (22) are arranged in the space 14 in a way that the top and bottom of the conveyor belt 23 are stepped. One of the first and second conveying areas 24 (25) is connected to each other, and the recovered waste can be conveyed out from the top down. In addition, when this embodiment is actually implemented, the conveying device 20 includes five first rollers 21 and two second rollers 22, and two of the first rollers 21 lean against the upper and lower sides of the front end of the machine 10. Moreover, the remaining first rollers 21 are arranged in an up-and-down manner at the rear end of the machine 10. At the same time, the first rollers 21 are adjacent to each other up and down. Those who are below are more likely to blame the front end of the machine 10; second, the second and second rollers 22 are located at the rear end of the machine 10, and are located between two adjacent first rollers 21 Therefore, when the conveyor belt is wrapped around the first and second rollers 22), a notch% can be formed between each of the conveyor areas 24 (25). The human wind device 30 mainly includes two pipe bodies 31 in the two notches 26 of the conveying device and-an air compressor (not shown in the figure) connected to the two pipe bodies ^ at the same time. Each of the pipe bodies 31 has an air outlet 311 opened along its long axis, and the air outlet 311 faces the opening 20 1235102 of the notch 26, and the i-pressure fine machine can generate a local pressure airflow, and The high-pressure airflow is introduced into the two pipe bodies 31 and then discharged through the two air outlets 311. Secondly, the main purpose of the blower device 30 is to spray gas toward the recovered waste materials that are in a falling state, so that the batts b can be blown up from the rubber powders a5, so it is not necessarily limited to air The combined structure of the compressor and the pipe body, and other combined structure factors having the same effect are regarded as equivalent implementations of the present invention. The dust collecting device 40 is composed of two components such as two air buckets 41 (42), an exhaust motor and a dust collecting cylinder. However, the aforementioned components are of a known structure, and 10 will not be described and illustrated here. Only the wind bucket 41 (42) related to the present invention is displayed. The two wind buckets 41 (42) each have an air inlet 411 (421), and one of the wind buckets 41 is located above the front section of the first conveying area 24, and the air inlets 411 of the wind bucket 41 face toward the Wait for the displacement path of the recovered waste material. Secondly, another wind hopper 42 is located between the first and the second rotation area 24 (25) I5, and the air outlet 421 of the wind hopper 42 also covers The notch 26 faces a displacement path of the recovered waste. The dust collecting device can suck the cotton wool in the recovered waste material through the second wind bucket 41 (42), and then concentrate it in the dust collecting cylinder. Therefore, with the above-mentioned structure, when the recovered waste mixed with the rubber powder a and the cotton wool b 20 enters the rubber powder screening machine of the present invention, it will pass through the first conveying zone 24 in advance. In the first conveying area 24 " Front section = Fang Zhi's wind bucket 4 will be firstly sent by the cotton bat b in the middle of his air outlet 411 __ 二 ", and the remaining recovered waste is then driven by the 1235102 of the conveyor core The “forward” is because of the stepped relationship between the two conveying areas 21 (22). Therefore, the recovered waste material is used in combination with the gas ejected by the blower set 30 at the same time by using the height drop. The cotton wool b in the middle is blown up from the rubber waists in the end a, thereby, the other one located between the two conveying areas 24 (25) —Xifeng 5 bucket 42 will immediately pass the cotton wool b blown by it. The air inlet 421 takes people and concentrates in the dust collecting tube of the dust collecting device 40 to further remove the b content of cotton in the recovered waste. In short, the way in which the recovered waste is scattered downward multiple times is used. , Forcing cotton batting b not to be mixed in rubber powder a & at the same time, and then spraying air The rubber powder a is separated from the cotton wool b, and the separated cotton wool b is collected by a dust collecting device, so that the proportion of the rubber powder a obtained in the recycled waste material obtained at the end can be greatly increased, thereby recycling and remanufacturing the molten waste It has wider applicability, so it can reduce the input and manufacture of new raw materials on the market, reduce the consumption of resources, and achieve the purpose of environmental protection and regeneration. 15 & outer 'with the third figure is the second preferred embodiment of the present invention Glue powder screening machine 2, its structure is roughly the same as the above-mentioned embodiment, and the most complex: the difference is that the conveying device 6G has six rollers M opposite each other, and the outer roller 61 is covered with an endless conveyor belt &, thereby forming a first and a second rotation area adjacent to each other in steps.
