Description

Technical Field

[0001] This utility model relates to the technical field of plastic parts production equipment, specifically to a waste material crushing device for plastic parts production. Background Technology

[0002] Waste crushing equipment for plastic parts production is widely used in plastic recycling, plastic reuse, and plastic product manufacturing. It can process various types of plastic waste, such as plastic film, plastic bottles, plastic buckets, and plastic pipes. Different types of plastic waste crushing equipment have slightly different working principles, but in general, they all use mechanical force to crush plastic waste into smaller fragments. These fragments can be further processed into plastic granules or used in the production of other plastic products.

[0003] Existing crushing devices for plastic parts production lack a portable, automated feeding structure, such as the plastic parts crushing device disclosed in application number CN202021942466.0. The absence of an automated feeding structure means that plastic waste must be manually transported to the crusher's inlet, increasing labor intensity and reducing production efficiency. Manual feeding can lead to problems such as waste scattering and uneven accumulation, affecting the crushing effect. During manual feeding, workers frequently need to contact the crusher and its inlet, increasing safety risks. If the crusher becomes clogged or malfunctions during operation, manual cleaning and repair are required, potentially posing safety hazards. Furthermore, the amount and speed of waste fed during manual feeding may be uneven, resulting in unstable load on the crusher during operation and affecting the crushing effect.

[0004] Therefore, it is necessary to invent a waste crushing device for plastic parts production to solve the above problems. Utility Model Content

The crushing roller 303 and the crushing box 301 are fixedly installed on the surface of the crushing frame 1. The top of the crushing box 301 is provided with a baffle frame 302. The crushing roller 303 is provided on both sides of the inside of the crushing box 301. One end of the crushing roller 303 is connected to the upper side of the starting frame 2. The toothed blocks 304 are fixedly provided on both sides of the inner wall of the crushing box 301. Several crushing teeth are provided on the surface of the crushing roller 303, and each crushing tooth corresponds exactly between two toothed blocks 304. A bearing seat 305 is provided at the installation position of the crushing roller 303 and the inner wall of the crushing box 301. Two bearing seats 305 are installed according to the number of crushing rollers 303.

[0024] A feeding rack 4 is fixedly installed on the other side of the crushing rack 1. A conveyor belt 401 is installed in the middle of the feeding rack 4. The surface of the conveyor belt 401 is provided with anti-slip pads. The top of both sides of the feeding rack 4 and the conveyor rack 5 are provided with the same protective plate 402. One end of the feeding rack 4 is connected to the conveyor rack 5. A base 6 is provided on the inner bottom surface of the crushing rack 1. A receiving box 7 is provided above the base 6. Two docking blocks 701 are installed on one edge of the outer wall of the receiving box 7. Two corresponding docking grooves 702 are opened on the inner side wall of the crushing rack 1. Self-locking wheels 703 are installed at the four corners of the bottom surface of the receiving box 7. Push-in grooves 704 with matching wheel widths of the self-locking wheels 703 are opened on both sides of the surface of the base 6. A connecting frame 8 is provided at the end of the feeding rack 4 that connects with the crushing mechanism 3.

[0025] The working principle of this practical application is as follows:

[0026] Refer to the instruction manual appendix Figure 1-5 For this type of waste crushing device used in plastic parts production, the power supply box 201 first provides power to the entire device. The driver 202 receives the power and generates driving force, which is transmitted to the crushing roller 303 through the drive shaft 203. A washer 204 is installed at the output end of the drive shaft 203 to protect the drive shaft 203 and reduce wear. The conveyor belt 401 in the middle of the feeding rack 4 is responsible for conveying the plastic waste from one end to the other until it enters the crushing mechanism 3. The surface of the conveyor belt 401 is provided with anti-slip pads to prevent the material from slipping during the conveying process. Protective plates 402 are provided on the top of both sides of the feeding rack 4 and the conveyor rack 5 to protect the operators from material splashes or damage caused by machine operation. The plastic waste enters the crushing box 301 via the conveyor belt 401, where it is clamped and crushed by two crushing rollers 303. The crushing teeth on the surface of the crushing rollers 303 cooperate with the toothed blocks 304 on the inner wall of the crushing box 301 to shear and crush the waste. The bearing seat 305 provides support for the crushing rollers 303 and ensures their stable rotation. The crushed plastic particles fall into the receiving box 7 through the bottom of the crushing box 301. The receiving box 7 is used to collect the crushed plastic particles. The outer wall docking block 701 of the receiving box 7 engages with the docking groove 702 on the inner side wall of the crushing rack 1 to ensure that the receiving box 7 is placed stably. When the receiving box 7 is full, it can be easily removed and replaced by the self-locking wheel 703 and the push-in groove 704.

[0027] Before using this device, first check that the power supply box 201 is securely connected to ensure a normal power supply. Check that the driver 202, drive shaft 203, and crushing roller 303 are intact to ensure the transmission system is functioning correctly. Check that the conveyor belt 401 is properly tensioned and that the anti-slip pads are intact. Clean the crushing box 301 and receiving box 7 to ensure there are no residues. Turn on the power supply box 201 and start the driver 202. Observe whether the conveyor belt 401 starts moving to ensure the feeding system is functioning correctly. Slowly place the plastic waste at the beginning of the conveyor belt 401, avoiding adding too much at once. Observe the crushing process. The rotation of the material roller 303 should be monitored to ensure that the waste material is properly clamped and crushed. If the waste material is found to be stuck or the crushing effect is not good, the machine should be stopped immediately for inspection and troubleshooting. The loading status of the receiving box 7 should be checked regularly, and the full receiving box 7 should be replaced in time. After the crushing task is completed, the power supply of the driver 202 should be turned off first. After all the waste material on the conveyor belt 401 has entered the crushing box 301 and been crushed, the main power supply of the power box 201 should be turned off. The residue in the crushing box 301 and the receiving box 7 should be cleaned up. The equipment should be kept clean. The equipment should be inspected and maintained regularly, including replacing worn parts and lubricating the transmission system.
