Description

Technical Field

[0001] This utility model relates to the field of cardboard waste treatment technology, specifically to a shredder and recycling machine based on environmentally friendly cardboard waste recycling. Background Technology

[0002] Environmentally friendly cardboard boxes are packaging boxes made from environmentally friendly materials, emphasizing energy conservation, emission reduction, and green production. Their main characteristics are the use of recyclable and biodegradable materials, such as pulp, bamboo pulp, and straw pulp, which significantly reduces environmental pollution. Waste cardboard boxes can be recycled and reused to manufacture new paper products.

[0003] Recycling cardboard waste requires first shredding the cartons. Existing shredders typically use a dual-shaft independent drive design, crushing waste paper, cardboard, and other materials into small pieces through shearing and compression. Therefore, their use has the following shortcomings:

[0004] 1. As the core component of the crushing process, the blades are prone to dulling and chipping after long-term use, so they need to be replaced regularly. The blades themselves are installed on the rotor inside the housing by screws, etc. When removing them, tools such as Phillips screwdrivers and wrenches are needed inside the housing to remove the blades. Care must be taken to avoid the blade edges when removing them, making replacement inconvenient.

[0005] 2. The size of the feeding port is fixed. If the feeding is too fast, it is easy to overload, causing blockage and affecting the crushing operation. Utility Model Content

[0006] I. Technical problems to be solved

[0007] The technical problem this invention aims to solve is the inconvenience of replacing cutting tools and the easy blockage of the feeding port.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] As attached Figure 1 As shown, the shredder and recycling machine based on environmentally friendly cardboard waste recycling includes a shredder 1 and a shredder mechanism set inside the shredder 1. The longitudinal section of the shredder 1 in the left and right directions is an inverted trapezoid, a rectangle and an inverted trapezoid from top to bottom, and it is open at both the top and bottom. Cardboard waste is poured into the shredder 1 from the top and shredded by the shredder mechanism for further recycling.

[0033] To facilitate the replacement of the crushing mechanism, combined with the attached Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 5As shown, the front side of the crushing box 1 is provided with a through groove 2. The crushing mechanism includes an insert plate 3 that is inserted into the through groove 2. A limiting rod 14 that passes through the insert plate 3 is inserted into the side wall of the crushing box 1. The two ends of the limiting rod 14 extend out of the crushing box 1, and the extended side wall is provided with threads. Nuts 15 are threaded onto the two ends of the limiting rod 14, so that the insert plate 3 is inserted into the through groove 2 and fixed by passing through the limiting rod 14. The position of the limiting rod 14 is fixed by tightening the nuts 15 at both ends of the limiting rod 14, so that the insert plate 3 is easy to install and remove.

[0034] The front end of the insert plate 3 is provided with a motor 4 facing each other. The motor 4 passes through the insert plate 3 and is connected to a rotating rod 5. After the motor 4 is started, the rotating rod 5 rotates. The rear end of the rotating rod 5 is connected to a support rod 16. The inner wall of the crushing box 1 is provided with a hole 17 that cooperates with the support rod 16 to enhance the rotational stability of the rotating rod.

[0035] The rotating rod 5 has multiple through holes 6 evenly distributed along its length on its side wall. A cutting blade assembly 7 is sleeved on the side wall of the rotating rod 5. The cutting blade assembly 7 consists of a ring and cutting blades evenly distributed around the outside of the ring along its circumference. A connecting rod 8 is inserted into the side wall of the ring and passes through the through holes 6. The connecting rod 8 is fixed by passing through the through holes 6 of the rotating rod 5. After the crushing mechanism is removed from the crushing box 1, the cutting blade assembly 7 can be removed by pulling out the connecting rod 8, achieving quick disassembly and assembly. The cutting blade assemblies 7 on the two rotating rods 5 are staggered to enhance the shearing efficiency and avoid material jamming.

[0036] Furthermore, the upper and lower ends of the connecting rod 8 are connected to rubber sheets 18 with a diameter larger than that of the connecting rod 8. The connecting rod 8 is manually inserted through the through hole of the rotating rod 5 to prevent the connecting rod 8 from loosening and detaching.

[0037] Example 2

[0038] Based on Example 1, to avoid material clogging the feed inlet, as shown in the attached... Figure 2 Appendix Figure 3 and attached Figure 6 As shown,

[0039] The upper part of the inverted trapezoidal crushing box 1 is provided with an anti-blocking mechanism. The anti-blocking mechanism includes a frame 9 that is attached to the inner wall of the crushing box 1. Multiple cutting blades 10 with their blades facing upward are evenly arranged along the left and right sides of the frame 9. After the material is placed on the cutting blades 10, it can be cut to prevent large pieces of material from blocking the feed inlet. The left and right inner walls of the crushing box 1 are provided with semi-circular rubber strips 21 that are attached to the upper part of the frame 9. These strips are used to limit the position of the frame 9, prevent it from moving up and down, and facilitate the removal of the anti-blocking mechanism by manual pulling.

[0040] Furthermore, a T-shaped pressure block 19 is provided above the crushing box 1. An electric telescopic rod 20 is connected between the front and rear side walls of the pressure block 19 and the crushing box 1. The electric telescopic rod is a DC electric drive type and can be loaded with 500-800N. The electric telescopic rod 20 drives the downward pressure so that the cutting blade 10 with the blade facing upward can pre-cut the input carton and avoid large pieces of material from blocking the feed inlet.

[0041] Furthermore, in conjunction with the appendix Figure 3 As shown, the side wall of the crushing box 1 is provided with a corresponding telescopic plate 11, and a spring 12 is provided inside the telescopic plate 11. The side wall of the crushing box 1 is provided with a vibration motor 13, so that the crushing box 1 can vibrate up and down after the vibration motor 13 is started. That is, the probability of blockage is significantly reduced by the dual mechanism of pre-cutting + vibration anti-blocking, so as to avoid affecting the crushing operation.
