[0035] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0036] Embodiment 1

[0037] like Figure 1-3As shown, a PVC film waste recycling and processing device proposed by the present invention includes a water washing mechanism for separating PVC film and impurities, a waste chamber 1 for assisting PVC film processing, and a crushing mechanism for crushing PVC film, and the three processing steps are arranged in sequence;

[0038] The waste chamber 1 has a built-in chamber, and a double-opening sealing door 11 is installed on the front surface to close the chamber of the waste chamber 1. An openable feeding door 12 is installed on the side wall, and a feeding port is exposed after opening, and PVC film waste is placed through the feeding port;

[0039] A material taking support plate 3 which can slide forward and backward is installed at the bottom of the waste chamber 1;

[0040] The transverse compacting mechanism includes a fixed compacting member 41 and a first compacting member 44 arranged on both sides of the material taking support plate 3. The fixed compacting member 41 is fixedly designed. A first hydraulic device 42 is arranged on one side of the first compacting member 44. A first push rod 43 connected to the first compacting member 44 is installed at the output end of the first hydraulic device 42.

[0041] The vertical compacting mechanism comprises a second compacting member 53 arranged above the material taking support plate 3 , a second hydraulic device 51 is arranged above the second compacting member 53 , and a second push rod 52 connected to the second compacting member 53 is installed at the output end of the second hydraulic device 51 .

[0042] It should be noted that the area after the fixed compacting member 41, the first compacting member 44 and the second compacting member 53 are closed together is a compacting cavity, and the area after separation is used for placing the pre-treated PVC film waste and waiting for compaction in the cavity.

[0043] In one embodiment, after the PVC film waste is placed, the transverse compaction mechanism first works, the first hydraulic device 42 drives the first push rod 43 at the output end to extend, and the loose waste is compressed and contracted transversely during the process of the first compaction member 44 approaching the fixed compaction member 41;

[0044] The vertical compaction mechanism works, the second hydraulic device 51 drives the second push rod 52 at the output end to extend, and the second compaction member 53 presses down to vertically compact and shrink the loose waste;

[0045] Because the cross-section of the compaction cavity is a "hexagonal" structure, the shrunk waste has a hexagonal column structure with increased hardness. Its multiple side walls increase the contact area with the crushing tool, making subsequent crushing easier.

[0046] In order to facilitate the removal of the waste after compaction, further, the material removal support plate 3 is a movable structure. The sealing door 11 is opened, and the support plate 3 is slid out along the groove at the bottom of the chamber to remove the compacted waste outside the chamber.

[0047] The transverse compacting mechanism also includes a guide rail 45, and the first compacting member 44 slides back and forth along the groove of the guide rail 45. The setting of the guide rail 45 can improve the smoothness of the compacting member 44 during the pushing process, reduce its movement resistance, and reduce the loss of the first hydraulic device.

[0048] Among them, the end fitting surface of the guide rail 45 and the first compacting member 44 is an inclined surface, which facilitates the forming of the hexagonal columnar structure compacted waste, and during the pushing process, the waste on the slot is pushed by the inclined surface of the first compacting member 44 to the lateral compacting interval to prevent the waste from clogging the slot.

[0049] Embodiment 2

[0050] like Figure 1-4 As shown, the fan mechanism includes an air cooling box 61 arranged in the chamber of the waste chamber 1, the second compacting member 53 slides along the side wall of the air cooling box 61, and the side wall is equipped with a ventilation plate 63 with ventilation holes, and the air inlet end of the air cooling box 61 is connected to an air inlet pipe 62 that passes through the waste chamber 1.

[0051] In another embodiment, the air cooling box 61 is used to deliver cold air to assist in drying the waste placed in the chamber, the air inlet pipe 62 is used for air intake, and the ventilation plate 63 blows cold air into the chamber through the ventilation holes.

[0052] It should be noted that the ventilation plate 63 and the feeding door 12 are arranged in parallel, and a hollow ventilation hole is opened on the feeding door 12 to form an air duct between the ventilation plate 63 and the feeding door 12 for transmission of cooling wind, which contacts the waste for air drying during the transmission process.

[0053] In an optional embodiment, the fixed compacting member 41, the first compacting member 44 and the second compacting member 53 have a built-in heating mechanism, which includes a compacting block 71, and the compacting block 71 has a built-in heater 73, and the heat release end of the heater 73 is connected to a heat conducting plate 72 installed on the inclined end surface of the compacting block 71.

[0054] The compacted piece is a pressing block 71, and the heater 73 inside the pressing block releases heat when in operation. The heat is transferred to the waste material in contact with the pressing block through the heat conducting plate 72, so as to perform thermal drying and shaping on the surface of the waste material.

[0055] like Figure 5 As shown, the water washing mechanism includes a water washing tank 21 , a separation net 23 for separating impurities is installed in the middle layer of the water washing tank 21 , and a water pipe 22 penetrating the inner and outer walls of the water washing tank 21 is arranged above the separation net 23 .

[0056] As an example of washing waste: PVC film waste mixed with impurities and debris is placed in the washing tank 21 and retained above the dividing net 23. Cleaning water is input through a water pump connected to the water pipe 22, and the waste is separated by cooperating with the openings on the dividing net. The PVC film waste retained on the upper layer is taken out and sent to the waste chamber 1 for compaction treatment.

[0057] like Figure 6 As shown, the crushing mechanism includes a crushing table 81, and a driving device 82 is arranged on one side of the crushing table 81. The output end of the driving device 82 is connected to a rotating shaft 83 that penetrates the inner cavity of the crushing table 81. A section of the outer wall of the rotating shaft 83 located in the inner cavity of the crushing table 81 is sleeved with a crushing roller 84, and a section of the outer wall located outside the crushing table 81 is sleeved with a gear set 86.

[0058] It should be noted that the gear set 86 includes two meshing gears, and the center of the other gear is equipped with a rotating shaft and a crushing roller that penetrates the inner cavity of the crushing table 81; the two gears of the gear set 86 are meshed and driven to drive the crushing roller 84 installed on the driving shaft 83 to rotate, and during the rotation process, the cutters on its outer wall alternately crush the waste.

[0059] As an example of waste crushing: compacted hexagonal prism structure waste is placed into the inner cavity of the crushing table 81, and the cutter contacts the waste during the rotation of the crushing roller 84. The hardened waste can be fully crushed, solving the problem of easy obstruction of crushing due to its low material hardness.

[0060] In order to improve the crushing efficiency of the crushing table 81, further, a fixed knife table 85 cooperating with the crushing roller 84 is installed on the inner wall of the crushing table 81, which is divided into two sides and the middle for partial crushing to improve the crushing efficiency.

[0061] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the appended claims, or the equivalent forms of such scope and boundaries.
