Description

Technical Field

[0001] This utility model relates to the field of fiberboard waste recycling technology, specifically a waste recycling device for medium and high density fiberboard production. Background Technology

[0002] Medium and high density fiberboard are widely used in people's daily lives, such as in the production of furniture accessories such as mattresses, sofa cushions, seat cushions, and filter screens, as well as sound insulation boards for buildings.

[0003] Fiberboard production equipment typically includes a recycling system to collect debris generated during production. However, larger debris generated during subsequent gluing and cutting processes requires manual processing before recycling. However, problems often arise when using a waste recycling system to pulverize medium- and high-density fiberboard (MDF). Specifically, due to the relatively hard texture of MDF, thorough pulverization is often difficult. This incomplete pulverization results in the fiberboard being broken down into small fragments rather than fine powder. Consequently, the pulverization effect cannot be maximized, thus affecting the efficiency of the waste recycling system and the reuse value of the MDF.

[0004] Therefore, this utility model provides a waste recycling device for medium and high density fiberboard production to solve the above problems. Utility Model Content

[0022] 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.

[0023] This utility model provides a device for recycling waste materials from medium and high density fiberboard production, such as... Figure 1-4 As shown, the waste recycling device for medium and high density fiberboard production includes a support 1. A crushing chamber 2 is fixedly installed at the upper end of the support 1. A feeding hopper 3 is fixedly installed at the upper end of the crushing chamber 2. A first motor 4 is fixedly installed at the rear side of the crushing chamber 2. Two sets of crushing rollers 5 are rotatably installed inside the feeding hopper 3. Gears 6 are fixedly installed at the front end of each of the two sets of crushing rollers 5. The two sets of gears 6 mesh with each other. A protective cover 7 is fixedly installed at the front side of the crushing chamber 2. A waste shaking screen drive assembly is provided at the lower end of the crushing chamber 2. A conveying assembly is provided at the lower end of the support 1 and the drive assembly.

[0024] When the device is working, the waste material from the production of medium and high density fiberboard is first fed into the feed hopper 3. Through the cooperation of two sets of crushing rollers 5 and gears 6, the waste material can be crushed. The crushed waste material slides into the drive assembly, which shakes the crushed waste material to screen and disperse it. The screened and dispersed waste material is then conveyed by the conveying assembly. If there are still large pieces in the waste material, it can be fed back into the feed hopper 3 for further crushing through the conveying assembly. In this way, the fiberboard waste material can be effectively crushed, screened and conveyed, avoiding the tediousness and inconvenience of manual handling, and improving the crushing effect and recycling rate of fiberboard waste material.

[0025] The drive assembly includes a connecting pipe 8, which is fixedly installed at the lower end of four sets of crushing chambers 2. A tank 9 is fixedly installed at the right end of the connecting pipe 8, and a second motor 10 is fixedly installed at the upper end of the tank 9. A hollow turntable 11 is fixedly installed on the output shaft of the second motor 10.

[0026] During operation, the second motor 10 drives the perforated turntable 11 to rotate. The rotation of the perforated turntable 11 shakes and screens the waste material that falls into the tank 9, thereby separating the crushed waste material from the piled-up medium and high density fiberboard production waste. The screened waste material leaks down from the perforated turntable 11 and slides onto the conveying assembly.

[0027] The connecting pipe 8 is set at an angle, with the left end of the connecting pipe 8 being higher than the right end.

[0028] The inclined connecting pipe 8 design facilitates the pulverized waste material to slide down the inclined surface into the tank 9, avoiding blockage and accumulation.

[0029] The conveying assembly includes a first conveyor 12, which is fixedly installed on the lower end of the tank 9. The first conveyor 12 is fixedly connected to the lower end of the support 1. A collection box 13 is fixedly installed on the left end of the first conveyor 12. A second conveyor 14 is fixedly installed inside the left end of the collection box 13. The upper end of the second conveyor 14 is fixedly connected to the upper end of the feed hopper 3. A third motor 15 is provided on both the collection box 13 and the second conveyor 14. Multiple sets of claw plates 16 are arrayed on both the left and right sides of the second conveyor 14.

[0030] The waste material after the shaking screen is conveyed into the collection box 13 by the first conveyor 12, and the waste material in the first conveyor 12 is driven to rise and be fed into the feed hopper 3 again by the second conveyor 14 through multiple sets of claw plates 16, so as to re-crush the large pieces of waste material that have not been crushed.

[0031] The second conveyor 14 is set at an angle, and the lower end of the second conveyor 14 is not in contact with the inner wall of the collection box 13.

[0032] The inclined design of the second conveyor 14 allows waste materials to smoothly enter the feed hopper 3 during the conveying process, avoiding blockage and accumulation, and improving conveying efficiency.

[0033] The ends of the multiple sets of claw plates 16 on the second conveyor 14 are all composed of comb teeth, and the tooth spacing at the ends of the multiple sets of claw plates 16 is uniform.

[0034] The comb-like claw plate 16 design can effectively grab and transport waste materials. At the same time, the evenly distributed tooth spacing can ensure that the waste materials are evenly distributed during the transport process.

[0035] Working principle: When the device is working, the production waste of medium and high density fiberboard is first fed into the feed hopper 3. The first motor 4 drives the two sets of crushing rollers 5 and gears 6 to rotate in an intermeshing manner, thereby performing initial crushing treatment on the waste. Due to gravity, the crushed waste slides into the crushing chamber 2 and slides into the tank 9 along the connecting pipe 8 at the lower end of the crushing chamber 2. At this time, the drive component starts to work, and the second motor 10 drives the hollow turntable 11 to rotate at high speed, performing a shaking and screening treatment on the crushed waste, further dispersing the accumulated waste for subsequent screening and conveying. The waste material slides down through the outlet at the lower end of the tank 9 onto the first conveyor 12. After receiving the waste material, the conveying component transports it to the collection box 13 through the conveying action of the first conveyor 12. At this time, the second conveyor 14 located at the left end of the collection box 13 starts to work. Through the multiple sets of comb-shaped claw plates 16 set on it, the waste material is grabbed and transported. Therefore, the waste material can smoothly slide into the feed hopper 3 during the conveying process for secondary crushing. For large pieces of waste material that are not completely crushed, they are continuously fed into the feed hopper 3 for further crushing through the cyclic conveying of the conveying component until the ideal crushing effect is achieved.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
