[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1:

[0028] like Figures 1 to 6 As shown, the first embodiment of the present invention provides a recycling crusher for plastic woven bags, including a frame 1, a crushing chamber 2, a feed roller 5, a crushing roller 7 and a cleaning roller 8, wherein the frame 1 is made of welded steel and has sufficient strength and stability, and has support legs at the bottom for supporting the entire crusher. Casters (not shown in the figure) are provided at the bottom of the support legs to facilitate the movement and positioning of the equipment. The crushing chamber 2 is formed by covering the shell of the frame 1. A feed port 3 is provided on one side of the top of the crushing chamber 2 to facilitate the input of woven bags, and a discharge port 4 is provided at the bottom to discharge the crushed woven bag fragments.

[0029] like Figure 2 As shown, the feed roller 5 is rotatably mounted in the crushing chamber 2 near the feed inlet 3 via a bearing block. A motor is secured to the bottom of the housing, driving the feed roller 5 via a belt drive mechanism. Forty L-shaped feed claws 6 are evenly distributed around the circumference of the feed roller 5. The ends of the claws 6 facing away from the roller 5 are tapered, allowing them to easily penetrate the woven bag during rotation, facilitating the grabbing and cutting of the bag. The speed of the feed roller 5 is adjustable to vary the feed rate.

[0030] The crushing roller 7 is rotatably mounted in the crushing chamber 2 via a bearing seat and is also driven to rotate by a motor. The crushing roller 7 is provided with a cutting assembly, which includes fifty annular blades 12 and forty strip blades 13. The annular blades 12 and strip blades 13 are made of high-hardness alloy steel with high wear resistance and durability. Figure 5As shown, these annular blades and strip blades 13 are arranged in a crisscross pattern, with the annular blades 12 surrounding the crushing roller 7 and the strip blades 13 parallel to the axis of the crushing roller 7. Each grid enclosed by the annular blades 12 and strip blades 13 corresponds to a feed claw 6. The conveyor roller is provided with a knife groove 14 that cooperates with the strip blades 13 and annular blades 12 to ensure that the woven bags can be evenly cut during the crushing process.

[0031] The cleaning roller 8 is rotatably mounted in the crushing chamber 2 below the feed roller 5 through a bearing seat. A roller brush 9 is provided on the cleaning roller 8. The roller brush 9 is made of nylon fiber, which has high flexibility and wear resistance. Figure 2 When observed as a reference, the feed roller 5 rotates clockwise, while the cleaning roller 8 rotates counterclockwise, that is, the rotation direction of the cleaning roller 8 is opposite to that of the feed roller 5, and the rotation speed of the cleaning roller 8 is higher than that of the feed roller 5. In this way, the roller brush 9 can remove the woven bag fragments on the feed claw 6 from the curved tip of the feed claw 6, so that the woven bag fragments fall to the bottom, and the woven bag fragments are finally discharged from the discharge port 4.

[0032] Example 2:

[0033] In addition to the first embodiment, the present invention further incorporates a guide blade 10 on the inner wall of the crushing chamber 2 at the feed inlet 3. Made of rubber, the guide blade 10 exhibits a certain degree of elasticity and wear resistance. One end of the guide blade 10 is fixed above the feed roller 5, while the other end hangs down from the feed roller 5 due to gravity. This allows the guide blade 10 to use its own weight to press the woven bag entering the crushing chamber 2 from the feed inlet 3 toward the feed roller 5, ensuring that the woven bag is stably hooked by the feed claw 6 and enters the crushing area.

[0034] Example 3:

[0035] Based on the second embodiment, the utility model provides a metal sheet 11 on the part of the guide sheet 10 close to the feed roller 5, and the feed claw 6 scrapes against the metal sheet 11 to prevent the feed claw 6 from directly contacting the rubber guide sheet 10, thereby avoiding damage to the guide sheet 10.

[0036] To use the machine, first start the motor to rotate the feed roller 5, crushing roller 7, and cleaning roller 8. Then, the woven bag is dropped into the crushing chamber 2 through the feed port 3. The guide blade 10 presses the bag toward the feed roller 5. The feed claw 6 on the feed roller 5 grabs the bag and feeds it into the crushing area. Simultaneously, the cutting assembly on the crushing roller 7 begins to operate, cooperating with the feed roller 5 to cut the bag into small pieces. The resulting woven bag fragments are peeled off by the brush 9 on the cleaning roller 8 and fall into the discharge port 4. After crushing is complete, the motor is turned off, and any remaining fragments are cleaned from the discharge port 4 and the crushing chamber 2.

[0037] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
