Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a crushing device for PET film production, comprising: a base 1 and a crusher 2; the inlet end of the crusher 2 is provided with a material conveying mechanism;

[0024] The material conveying mechanism includes a feed bar 3, a conveyor 9 fixed in the feed bar 3, a drying hood 4 set in the feed bar 3, and a plurality of infrared heat pipes 5 arranged in sequence at the bottom of the drying hood 4;

[0025] The top of the drying hood 4 is fixed with multiple connecting arms 6, and one end of each connecting arm 6 is fixed with a handle 7. The outer wall of the feed chute 3 is provided with multiple hanging holes 8, and the handle 7 is hung in the multiple hanging holes 8 respectively.

[0026] The wet film waste is fed into the feed chute 3 and conveyed towards the crusher 2 by the conveyor 9. During the conveying process, the film waste is dried by multiple infrared heat pipes 5 in the drying hood 4 to remove moisture. In the conveying mechanism, the drying hood 4 is installed and used in conjunction with the hanging port 8 of the feed chute 3 through the handle 7 of the connecting arm 6. It can be directly lifted and placed for disassembly and assembly, which is convenient for inspection and maintenance.

[0027] More preferably, a collection frame 12 is inserted into one end of the base 1, and the outlet end of the crusher 2 faces the collection frame 12 and is provided with a discharge pipe 13;

[0028] One end of the base 1 has an insertion port that fits into the collection frame 12 for positioning and placement of the collection frame 12. The top frame opening is used to receive the broken material falling from the discharge pipe 13, which is convenient for disassembly and assembly.

[0029] More preferably, the conveyor 9 includes its conveyor belt, and the outer wall of the conveyor belt has a plurality of first openings 10;

[0030] The conveyor 9 uses its conveyor belt to transport film waste. When the waste is transported to the drying position, the first opening 10 provides a certain amount of ventilation to assist the drying operation.

[0031] More preferably, the irradiation surface of the infrared heat pipe 5 is arranged facing the conveyor 9, and a second opening 11 is provided on the outer wall of the feed drain 3 near the infrared heat pipe 5;

[0032] The infrared heat pipe 5 faces the conveyor belt of the conveyor 9 for drying, while the second port 11 of the feed outlet 3 is used to assist in the exhaust during drying.

[0033] More preferably, a motor 14 is fixed to the top of the base 1, and the motor 14 is connected to the power receiving end of the crusher 2.

[0034] The motor 14 and the crusher 2 are driven by a pulley and belt, and the motor 14 drives the crusher 2 to perform the crushing operation.

[0035] One specific application of this embodiment is as follows: slightly damp film waste is directly conveyed into the crusher 2 via the conveyor 9 of the feed tray 3. During the conveying process, the film waste located on the conveyor belt of the conveyor 9 will slowly pass under the drying hood 4 and be irradiated by multiple infrared heat pipes 5 under the drying hood 4. After drying, it falls into the connected crusher 2, is shredded by the blades in the crusher 2, and then falls into the collection frame 12 inserted into the base 1 through its discharge pipe 13. After the operation is completed, the personnel can pull out the collection frame 12 to transfer the crushed film waste. Under long-term operation, because the infrared heat pipes 5 are frequently heated, they need to be inspected and maintained frequently to ensure that each infrared heat pipe 5 is operating normally. When inspecting and maintaining, the drying hood 4 can be disassembled and assembled by simply holding the handle 7 to lift it or placing it in the hanging port 8 of the feed tray 3.
