Description

Technical Field

[0001] This utility model belongs to the field of food container raw material crushing technology, specifically a food container raw material crushing device. Background Technology

[0002] Disposable fast food containers have shifted from foam lunch boxes to environmentally friendly ones. The original foam lunch boxes were phased out because they were not heat-resistant and the manufacturing process damaged the environment. They have been replaced by plastic lunch boxes, paper lunch boxes, wooden lunch boxes, biodegradable lunch boxes, etc. Among them, plastic has the characteristics of low toxicity, high melting point, strong plasticity, simple production and relatively low cost, so it has become the mainstream material for manufacturing disposable fast food containers. When producing lunch boxes, the raw materials need to be crushed to facilitate subsequent production.

[0003] Meanwhile, a raw material crushing device for the production of disposable lunch boxes, with application number CN202222468343.3, includes a crushing box and a control box. The crushing box has a feeding hopper installed on the top. A crushing shaft is rotatably installed inside the upper part of the crushing box via a bearing seat. Four rows of crushing blades are installed in a circular array on the crushing shaft. A second diversion channel is installed inside the crushing box below the second diversion channel. A vibrating screen is installed at an angle inside the crushing box below the second diversion channel. Spring seats are installed at the four corners of the bottom of the vibrating screen. The four spring seats are fixed on fixed blocks. The four fixed blocks are installed in pairs on the inner walls of both sides of the crushing box. A first diversion channel is installed at the bottom of the vibrating screen. A vibrating motor is installed on the outer shell of the first diversion channel. Baffles are installed on the front and rear sides of the upper end of the vibrating screen. A discharge chute is embedded in the right side plate of the crushing box located on the right side of the vibrating screen. A discharge port is provided in the middle of the bottom of the crushing box. An electromagnetic valve is installed on the discharge port.

[0004] However, the following problems were found in the implementation of the relevant technology: although it can screen the raw materials, the unqualified raw materials after the initial screening cannot be directly crushed again, which requires the unqualified raw materials to be collected and crushed again, thus reducing the crushing efficiency. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a food container raw material crushing device, which has the advantage of conveniently crushing raw materials that fail the initial crushing directly into secondary crushing.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model facilitates the crushing of lunch box raw materials through the crushing roller, and the eccentric wheel facilitates the upward movement of the screening plate. It also facilitates the up-and-down vibration of the screening plate in conjunction with the elastic pressure of the outward expansion spring, which facilitates the screening of the lunch box raw materials that fall onto the screening plate after crushing. This allows the lunch box raw materials with qualified crushed size to be discharged from the inside of the crushing box through the discharge hopper.

[0016] 2. This utility model facilitates the re-transportation of unqualified lunch box raw materials to the crushing roller for secondary crushing through the conveying action of the first and second spiral blades. This avoids the need to re-sort and collect the lunch box raw materials that are unqualified after the first crushing and then crush them again, thus improving the crushing efficiency of lunch box raw materials.

A connecting rod 26 is connected between the two eccentric wheels 25.

[0031] Furthermore, two through slots are provided at the bottom of the screening plate 23, and the surfaces of the two eccentric wheels 25 respectively fit into the two through slots.

[0032] Furthermore, the conveying assembly 3 includes a first conveying cylinder 31, a first spiral blade 33, and a second conveying cylinder 35. The first conveying cylinder 31 is located on the other side of the crushing box 4. A second drive source 32 is connected to the top of the first conveying cylinder 31.

[0038] Working principle: First, the fourth drive source 8 is activated beforehand, driving the transmission gear 9 to rotate, which in turn drives the two crushing rollers 6 to rotate. Simultaneously, the first drive source 24 is activated beforehand, driving the two eccentric wheels 25 to rotate, smoothly lifting the screening plate 23 upwards. Simultaneously, the elastic downward pressure of the outward-expanding spring 22 causes the screening plate 23 to elastically reset and move downwards when the eccentric wheels 25 are not in contact with the screening plate 23, resulting in up-and-down vibration of the screening plate 23. After the above preparations are completed, the lunchbox raw materials are fed into the crushing chamber 4 through the feed hopper 5. At this time, the crushing rollers 6 crush the lunchbox raw materials, and the crushed lunchbox raw materials fall into the feed hopper. The food container material is screened on the vibrating screen plate 23. The food container material that meets the size requirements after crushing is discharged from the crushing box 4 through the feed hopper 7. The food container material that does not meet the size requirements after crushing enters the first conveying cylinder 31. The first spiral blade 33 is driven to rotate by the second drive source 32 and the second spiral blade 37 is driven to rotate by the third drive source 36. The food container material that does not meet the size requirements is conveyed to the crushing roller 6 for secondary crushing through the conveying action of the first spiral blade 33, the connecting pipe 34, the conveying action of the second spiral blade 37 and the discharge action of the feed pipe 38. There is no need to collect the food container material that does not meet the size requirements separately and crush it in a centralized manner, which improves the convenience and efficiency of crushing and makes the operation simple.
