Description

Technical Field

[0001] The utility model relates to the technical field of fiberboard production and processing, in particular to a cellulose board waste material crushing and recycling device. Background Art

[0002] Cellulose board, commonly referred to as fiberboard, is a man-made board whose main raw materials are wood fiber or other plant fiber, which can come from trees, crop waste or other plant materials. During the manufacturing process, these fibers are mixed with urea-formaldehyde resin or other suitable adhesives and cured into boards through high temperature and high pressure treatment.

[0003] During the production and processing of cellulose board, there is likely to be excess waste after trimming. Generally, a roller crusher is used to crush the waste and then recycle it. The roller crusher crushes the material by squeezing two crushing rollers. Since cellulose board is a man-made board made of wood fiber with a suitable adhesive added, most of the waste of cellulose board contains adhesive, which causes the crushed wood fiber to be easily pressed together by the adhesive to form block-like wood debris, which needs to be broken up before continuing the processing operation. Therefore, a cellulose board waste crushing and recycling device is proposed here to solve the above problem. Summary of the invention

[0004] The purpose of the utility model is to provide a cellulose board waste crushing and recycling device to solve the problems existing in the prior art, which is characterized by comprising:

[0005] A crushing box, on the upper part of which a crushing mechanism and a driving mechanism for transmitting the crushing mechanism are installed;

[0006] The breaking mechanism includes a control motor and a transmission rod rotatably connected to the lower part of the crushing box, the transmission rod is horizontally arranged along the length direction of the crushing box, the transmission rod is transmission-connected to the output shaft of the control motor, and a plurality of breaking parts are arranged on the surface of the transmission rod; the breaking parts include a collar fixedly welded on the surface of the transmission rod and a plurality of breaking rollers evenly installed around the collar, and the cross-section of the breaking roller is crescent-shaped.

[0007] In some embodiments, the crushing mechanism includes two crushing rollers, the central axes of the two crushing rollers are located on the same horizontal line, and the crushing teeth arranged on the surfaces of the two crushing rollers are meshed with each other; two groups of driving mechanisms are arranged, and the two groups of driving mechanisms are installed on the surface of the crushing box relative to the crushing rollers.

[0008] The cellulose board waste passes through the crushing roller and is squeezed by the two crushing rollers and the crushing teeth on the surface, thereby achieving the crushing effect, which can effectively crush the cellulose board waste into the required particle size and improve production efficiency.

[0009] In some embodiments, the crushing rollers are arranged along the width direction of the crushing box.

[0010] The crushing roller is arranged along the width direction of the crushing box. The crushing roller has a thicker diameter and a shorter length, which can enhance its crushing force. The thick crushing roller has a larger mass and inertia, and can exert a greater force in the crushing process. It is particularly beneficial for crushing waste materials with higher hardness or larger size, and can more effectively crush stubborn waste materials.

[0011] In some embodiments, a feeding hopper is welded on the top of the crushing box, a chassis is welded and fixed on the bottom of the crushing box, a conveyor belt is arranged on the bottom of the crushing box, the conveyor belt is installed on the top of the chassis, both ends of the conveyor belt extend to the left and right sides of the crushing box respectively, a gap is left between the surface of the conveyor belt and the crushing box, a side plate is rotatably connected to one side of the crushing box near the top of the conveyor belt, and the conveyor belt moves toward one side of the side plate.

[0012] The conveyor belt can continuously and quickly transport wood particles, improving production and processing efficiency. After opening the side panel, the conveyor belt can be turned on, and the materials transported on the surface of the conveyor belt can be transported outward from the side panel. Closing the side panel can seal the bottom of the crushing box to prevent wood chips from splashing out during the crushing process.

[0013] In some embodiments, a controller is installed on the front of the crushing box, and the controller is electrically connected to the driving mechanism, the control motor and the conveyor belt respectively.

[0014] Users can freely program the controller and adjust the control strategy according to production needs, so that the same set of equipment can adapt to different production processes and product types, improving the flexibility of production and processing.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. Since the scattering piece is arranged below the crushing mechanism, the crushed wood chips can directly fall on the scattering piece. The transmission rod is driven to rotate at a high speed by controlling the motor. During the rotation of the transmission rod, the scattering roller on its surface rotates at a high speed to quickly scatter and split the wood chips pressed together after crushing, so as to prevent the wood chips from agglomerating and affecting subsequent use.

[0017] 2. The cross section of the scattering hob is crescent-shaped. The center of gravity of the crescent-shaped tool is often close to the front end of the inner blade. This design facilitates the use of inertia to enhance the cutting force during use, while reducing the power required to control the motor. The crescent-shaped curve design allows the blade to form a larger contact area during cutting, which can more effectively transmit power during the cutting action, increasing the cutting depth and speed.

[0022] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-3 As shown, the utility model provides a cellulose board waste crushing and recycling device, which includes:

[0024] A crushing box 2, on the upper part of which a crushing mechanism and a driving mechanism 4 for driving the crushing mechanism are installed;

[0025] The breaking mechanism includes a control motor 52 and a transmission rod 5 rotatably connected to the lower part of the crushing box 2. The transmission rod 5 is horizontally arranged along the length direction of the crushing box 2. The transmission rod 5 is transmission-connected to the output shaft of the control motor 52. The surface of the transmission rod 5 is provided with a plurality of breaking parts; the breaking parts include a ring fixedly welded to the surface of the transmission rod 5 and a plurality of breaking rollers 51 evenly installed around the ring, and the cross-section of the breaking roller 51 is crescent-shaped.

[0026] The center of gravity of the crescent shape is often close to the front end of the inner blade, and this design facilitates the use of inertia to enhance the cutting force during use, while reducing the power required to control the motor 52. The curved design of the crescent shape allows the blade to form a larger contact area during cutting, which can more effectively transmit power during the cutting action, increasing the depth and speed of cutting.

[0027] Since the scattering piece is arranged below the crushing mechanism, the crushed wood chips can directly fall onto the scattering piece. By controlling the motor 52 to drive the transmission rod 5 to rotate at a high speed, the scattering roller 51 on the surface of the transmission rod 5 rotates at a high speed during the rotation of the transmission rod 5 to quickly scatter and divide the wood chips pressed together after crushing, so as to prevent the wood chips from agglomerating and affecting subsequent use.

[0028] In some embodiments, the crushing mechanism includes two crushing rollers 41, the central axes of the two crushing rollers 41 are located on the same horizontal line, and the crushing teeth 42 arranged on the surfaces of the two crushing rollers 41 are meshed with each other; two groups of driving mechanisms 4 are provided, and the two groups of driving mechanisms 4 are installed on the surface of the crushing box 2 relative to the crushing rollers 41.

[0029] The driving mechanism 4 of the crushing roller 41 generally includes a motor, a reducer, a coupling, a bearing seat, a transmission shaft, a base and a frame.

[0030] In this embodiment, two driving mechanisms 4 are used to drive two crushing rollers 41 to operate respectively. In other embodiments, one driving mechanism 4 can be set. By adding gear teeth or welding gears on the transmission shaft, the surface of the crushing box 2 is rotated to connect the auxiliary gear, and then a synchronous toothed belt is added to drive the transmission shaft and the auxiliary gear to rotate at the same time, and then the transmission shaft of the other crushing roller 41 is driven to rotate through the outer tooth block of the synchronous toothed belt, so that the two transmission shafts can rotate relative to each other to drive the crushing roller 41 to crush the waste, thereby reducing the cost of use.

[0031] The cellulose board waste is squeezed by the two crushing rollers 41 and the crushing teeth 42 on the surface thereof when passing through the crushing roller 41, thereby achieving a crushing effect, which can effectively crush the cellulose board waste into a desired particle size and improve production efficiency.

[0032] In some embodiments, the crushing roller 41 is arranged along the width direction of the crushing box 2 .

[0033] The crushing roller 41 is arranged along the width direction of the crushing box 2. The crushing roller 41 has a thicker diameter and a shorter length, which can enhance its crushing force. The thick crushing roller 41 has a larger mass and inertia, and can exert a greater force in the crushing process. It is particularly beneficial for crushing waste materials with higher hardness or larger size, and can more effectively crush stubborn waste materials.

[0034] A feeding hopper 21 is welded on the top of the crushing box 2, a chassis 1 is welded and fixed on the bottom of the crushing box 2, a conveyor belt 6 is arranged on the bottom of the crushing box 2, the conveyor belt 6 is installed on the top of the chassis 1, both ends of the conveyor belt 6 extend to the left and right sides of the crushing box 2 respectively, and a gap is left between the surface of the conveyor belt 6 and the crushing box 2, a side plate 22 is rotatably connected to one side of the crushing box 2 near the top of the conveyor belt 6, and the conveyor belt 6 moves toward the side of the side plate 22.

[0035] The feed hopper 21 and the chassis 1 are connected and fixed to the crushing box 2 by welding. Welding can directly form a continuous gapless structure between the two metal parts, thereby improving the integrity and rigidity of the overall structure. The strength of the weld can be close to or even equal to the strength of the parent material, making the welded structure very reliable in load-bearing capacity. The strength of the weld can be close to or even equal to the strength of the parent material, making the welded structure very reliable in load-bearing capacity.

[0036] When there is a lot of waste, the waste continues to enter the device from the feed hopper 21, and falls on the surface of the conveyor belt 6 after being crushed and scattered. After the side panel 22 is opened, the conveyor belt 6 is turned on, and the conveyor belt 6 can continuously and quickly transmit wood particles from the opening of the side panel 22. When there is less waste, the side panel 22 is closed, and the bottom of the crushing box 2 can be sealed. The crushed and scattered waste first falls on the surface of the conveyor belt 6. After the crushing and scattered are completed, the side panel 22 is opened and the conveyor belt 6 is turned on, which can prevent wood chips and debris from splashing out during the crushing process.

[0037] In some embodiments, a controller 3 is installed on the front of the crushing box 2, and the controller 3 is electrically connected to the driving mechanism 4, the control motor 52 and the conveyor belt 6 respectively.

[0038] The controller 3 may use a programmable logic controller 3 or an industrial controller 3. The user may freely program and adjust the control strategy according to production requirements, so that the same set of equipment can adapt to different production processes and product types, thereby improving the flexibility of production and processing.

[0039] The working principle of this specific implementation is:

[0040] The controller 3 controls the drive mechanism 4 and the control motor 52 to start, and the cellulose board waste falls between the two crushing rollers 41 through the feed hopper 21, and is squeezed and crushed by the two crushing rollers 41 and the crushing teeth 42 on the surface thereof, and the crushed wood chips fall onto the scattering roller 51. At this time, the control motor 52 drives the transmission rod 5 to rotate at a high speed. During the rotation of the transmission rod 5, the scattering roller 51 on its surface rotates at a high speed to quickly scatter and split the wood chip clusters pressed together after crushing.
