Description

Technical Field

[0001] This utility model relates to the field of plastic sample crushing technology, specifically a plastic sample crushing device. Background Technology

[0002] When testing plastic samples, the samples need to be crushed. Currently, this is done manually using scissors or needle-nose pliers. Crushing plastic samples with scissors or needle-nose pliers is time-consuming and labor-intensive, especially for large quantities or hard plastic samples. The crushing speed is extremely slow, which affects the testing efficiency. It is also difficult to precisely control the crushing force and angle of scissors or needle-nose pliers, resulting in inconsistent particle sizes after crushing, which affects the accuracy and reliability of subsequent tests. Utility Model Content

[0006] A cutting mesh, located in the middle of the crushing cylinder, is a metal mesh composed of multiple crisscrossing blades, used to cut plastic samples;

[0007] A pressure plate is raised and positioned above the blade mesh, and a sealing plate for sealing the feeding cylinder is provided on one side of the pressure plate;

[0008] A cutting blade, which is rotated and positioned below the blade mesh, is used to cut plastic samples extruded from the center of the blade mesh.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The combination of the blade mesh and the cutting blades achieves efficient crushing of plastic samples; the blade mesh, composed of multiple crisscrossing blades, can initially cut the plastic sample, while the rotating cutting blades further shred the extruded plastic sample into granules, greatly improving crushing efficiency; the blade mesh is connected to the support ring via a limiting rod and a limiting hole to prevent rotation during cutting, and also facilitates disassembly and cleaning; when the blade mesh needs cleaning or replacement, simply remove the top cover to easily remove the blade mesh from the support ring, making the operation simple and quick; the sealing plate on one side of the pressure plate can block the feeding cylinder when the pressure plate is pressed down, preventing material from entering the top of the pressure plate, and when the pressure plate is reset, the sealing plate and the feeding cylinder are misaligned, allowing the material inside the feeding cylinder to normally enter the top of the blade mesh for the next round of crushing.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 , 2As shown in Figures 3 and 4, this utility model provides a technical solution: a plastic sample crushing device, comprising: a crushing cylinder 1 with a feeding cylinder 5 fixedly attached to its side at an incline; a blade mesh 10 placed in the middle of the crushing cylinder 1, the blade mesh 10 being a metal mesh composed of multiple crisscrossing blades with the blade edges facing upwards, used for cutting plastic samples; a pressure plate 11 being raised and lowered above the blade mesh 10, a sealing plate 12 for sealing the feeding cylinder 5 being provided on one side of the pressure plate 11, and a cutting blade 9 being rotated and placed below the blade mesh 10 for cutting the plastic sample extruded from the middle of the blade mesh 10.

[0022] It should be noted that this utility model is equipped with an operation switch. When a plastic sample is placed into the feeding cylinder 5, the sample enters the top of the blade mesh 10 along the feeding cylinder 5. The control switch controls the hydraulic cylinder 3 and the motor 8 to work. The hydraulic cylinder 3 drives the pressure plate 11 to squeeze the plastic sample on the blade mesh 10. Under the action of squeezing, the blade mesh 10 cuts the plastic sample, so that the plastic sample passes through the hole of the blade mesh 10. The cutting blade 9 rotates to cut the plastic sample that has passed through, thereby crushing the plastic sample into granules, which can quickly crush the plastic sample without the need for manual cutting.

[0023] Please see Figure 2 , 3 As shown in Figure 4, the top of the crushing cylinder 1 is threadedly connected to a top cover 2, and a hydraulic cylinder 3 is fixedly connected to the top of the top cover 2. The output end of the hydraulic cylinder 3 is fixedly connected to the pressure plate 11. A support ring 13 is fixedly connected to the inner wall of the crushing cylinder 1. The blade mesh 10 is installed on the top of the support ring 13. A limiting rod is provided at the bottom of the blade mesh 10. A limiting hole that cooperates with the limiting rod is provided in the middle of the support ring 13 to prevent the blade mesh 10 from rotating during cutting.

[0024] It should be noted that the hydraulic cylinder 3 of this utility model drives the pressure plate 11 to move downward. The pressure plate 11 squeezes the sample on the top of the blade mesh 10. When the pressure plate 11 presses down, it blocks the feeding cylinder 5 to prevent the material from entering the top of the pressure plate 11 along the feeding cylinder 5. After the pressure plate 11 is reset, the sealing plate 12 is misaligned with the feeding cylinder 5, so that the material inside the feeding cylinder 5 can normally enter the top of the blade mesh 10. When the blade mesh 10 needs to be cleaned, the top cover 2 is removed, and then the blade mesh 10 is removed from the top of the support ring 13 for cleaning.

[0025] Please see Figure 3 , 4 As shown, a support beam 7 is fixedly connected inside the crushing cylinder 1 and below the blade mesh 10. A motor 8 is fixedly connected to the bottom of the support beam 7, and the output end of the motor 8 is fixedly connected to the cutting blade 9.

[0026] It should be noted that the supporting beam 7 of this utility model is located below the blade mesh 10. The pressure plate 11 presses the plastic sample onto the top of the blade mesh 10. Under the action of extrusion, the plastic sample moves downward from the hole in the middle of the blade mesh 10. The motor 8 drives the cutting blade 9 to rotate, and the cutting blade 9 cuts the extruded plastic sample.

[0027] Please see Figure 1 , 2 As shown in Figure 3, a material collection hopper 6 is fixedly connected inside the crushing cylinder 1 and below the supporting crossbeam 7. A discharge chute 4 is provided below the material collection hopper 6. The discharge chute 4 is inclinedly fixed inside the crushing cylinder 1, and one end of the discharge chute 4 extends out from inside the crushing cylinder 1.

[0028] It should be noted that the shredded material enters the collecting hopper 6, then gathers from the middle of the collecting hopper 6 and moves downwards. The gathered material then falls into the discharge trough 4 and moves downwards at one end, flowing out from the end of the discharge trough 4.
