Description

Technical Field

[0001] This invention relates to the field of waste slab processing technology, and in particular to a waste slab recycling and processing device. Background Technology

[0002] Waste boards are inevitably generated during the wood processing process. Waste boards refer to boards that are rejected during processing due to defects, size discrepancies, or substandard quality. They are considered waste materials in the production process. Waste boards are usually not directly discarded but are utilized as resources. For example, after being crushed, waste boards can be used as raw materials for particleboard, fiberboard, OSB, etc., which requires the use of recycling equipment.

[0003] Most crushing rollers in these machines have a fixed gap, which makes them less adaptable to different materials such as solid wood, composite board, and plywood. The resulting particle size fluctuates greatly and cannot meet the standardization requirements of engineered wood products. In addition, the process generates a large amount of wood dust, which causes a certain degree of environmental pollution. Furthermore, for waste boards with high moisture content, problems such as feeding jamming and crushing chamber blockage are also likely to occur.

[0004] Therefore, there is an urgent need for a waste slab recycling and processing device to solve the problems existing in the above-mentioned technologies. Summary of the Invention

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Reference Figures 1 to 7 As shown, this embodiment provides a waste slab recycling and processing device, including a support 1. A fixed baffle 7 is fixedly installed on the top of the support 1. A movable baffle 2 is arranged on the opposite side of the fixed baffle 7. Crushing rollers are installed on both the fixed baffle 7 and the movable baffle 2. The crushing rollers are driven by a drive motor 5. A movable support plate 3 and a fixed support plate 4 are fixedly connected to the bottom of the two drive motors 5 respectively. The movable support plate 3 is arranged correspondingly to the movable baffle 2. An adjustment mechanism is provided on the support 1 to adjust the position of the movable baffle 2. A gas collecting hood 6 is provided above the crushing roller. The gas collecting hood 6 is connected to a negative pressure box 62 through a negative pressure suction pipe 61. A filter box 63 is connected to one side of the negative pressure box 62. The filter box 63 is connected to the negative pressure suction pipe 61. A feed plate is provided on one side of the crushing roller. A conveyor belt 8 is connected to the top of the feed plate. A preheating component is provided on the conveyor belt 8.

[0021] In operation, waste slabs are conveyed via conveyor belt 8. During conveying, they are heated by a preheating component to reduce their moisture content. The slabs are fed between two crushing rollers via a feed plate, and the crushing rollers are rotated by a drive motor 5, thus crushing the slabs. Depending on the type of material, the position of the movable baffle 2 can be adjusted by an adjusting mechanism, thereby adjusting the distance between the crushing rollers to crush different types of materials. The dust generated during crushing is collected by a dust collection hood 6, and the dust is adsorbed by a negative pressure pipe and a negative pressure box 62. At the same time, the filter box 63 can filter impurities, facilitating later maintenance. In this invention, the bracket 1 provides a stable support foundation for the crushing rollers, ensuring that the crushing rollers do not shake during the crushing process and improving crushing accuracy. The adjusting mechanism adjusts the position of the movable baffle 2, thereby adjusting the distance between the two crushing rollers, which can adapt to slabs of different thicknesses and expand the applicability of the device. The negative pressure box 62 is used to adsorb dust and debris generated during the crushing process, preventing dust overflow and improving the working environment. The preheating component preheats and dehumidifies the slabs, reducing their moisture content and minimizing clogging.

[0022] Further refining the design, the preheating assembly includes a protective cover 91, within which dryers 92 are symmetrically installed, with the air outlets of the dryers 92 facing the conveyor belt 8. The protective cover 91 creates a semi-enclosed thermal environment, reducing heat loss and improving heat utilization. The symmetrical arrangement of the dryers 92 ensures uniform heating of the waste slabs, resulting in consistent preheating effects. Hot air acts directly on the surface of the waste slabs, leading to high heat transfer efficiency and rapid preheating, ensuring that the waste slabs reach the ideal temperature before entering the crushing zone.

[0023] Further refining the design, the conveyor belt 8 is supported by support legs 81, and the bottom of the protective cover 91 is symmetrically and fixedly connected with support crossbars 9, which are fixedly connected to the support legs 81. The support legs 81 provide stable foundation support for the conveyor belt 8, and the support crossbars 9 form an integrated rigid structure with the protective cover 91, preventing the protective cover 91 from shaking or shifting due to hot airflow or vibration, ensuring that the air outlet is always aligned with the conveyor belt 8, and improving the overall structural stability.

[0024] Further refining the design, the adjustment mechanism includes a movable block 11 slidably connected to the support 1. The support 1 has a groove 12, and a slider 114 is fixedly connected to the movable block 11. The slider 114 is located within and slidably connected to the groove 12. Limiting components abut against both sides of the slider 114, and these limiting components are threadedly connected to the support 1. The sliding of the slider 114 within the groove 12 provides precise guidance for the movement of the movable block 11, ensuring the parallel movement of the movable baffle 2 and preventing misalignment of the crushing roller. The limiting components abut against both sides of the slider 114 achieve double-sided clamping, ensuring uniform force on the movable block 11 and preventing tilting. The threaded connection allows the limiting components to be quickly locked or released by rotation, simplifying operation.

[0025] Further refining the design, the limiting component includes a limiting block 113 that abuts against the slider 114. A lead screw 111 is rotatably connected to the side of the limiting block 113 away from the slider 114. The lead screw 111 is threadedly connected to the bracket 1. The end of the lead screw 111 away from the limiting block 113 extends out of the bracket 1 and is fixedly connected to a handle 13. Rotating the handle 13 causes the lead screw 111 to rotate. Since the lead screw 111 is threadedly connected to the bracket 1, the rotation of the lead screw 111 generates displacement, causing the limiting block 113 to move, thereby facilitating the adjustment of the position of the movable block 11. After adjustment, the limiting block 113 contacts and abuts against the slider 114 to prevent the movable block 11 from shaking. The external handle 13 allows the operator to adjust the device without entering the equipment, making it safe and convenient.

[0026] Further refining the design, a compression spring 112 is fitted around the outer side of the lead screw 111. One end of the compression spring 112 is fixedly connected to the inner wall of the bracket 1, and the other end is fixedly connected to the side wall of the limit block 113. The compression spring 112 always applies force to the limit block 113, achieving automatic pre-tensioning and improving stability during operation.

[0027] Further refining the design, several screws 116 are evenly spaced at the bottom of the movable block 11. The screws 116 are threadedly connected to the movable block 11, and an abutment plate 117 is rotatably connected to the top of the screws 116. The abutment plate 117 contacts the bottom surface of the support 1, and a knob 115 is fixedly connected to the bottom of the screws 116. Rotating the knob 115 drives the screws 116 to rotate, and the rotation of the screws 116 can adjust the height of the abutment plate 117. When the abutment plate 117 is in contact with the support 1, it is in a fixed state, which greatly improves the stability and vibration resistance of the movable block 11 under crushing conditions. When the abutment plate 117 is disengaged from the support 1, it is convenient to adjust the movable block 11, thereby adjusting the gap between the two crushing rollers, which is suitable for different working conditions.

[0028] Further refining the design, a filter element 67 is detachably connected inside the filter box 63. Fixing strips 68 are fixedly connected to both the upper and lower sides of the inner wall of the filter box 63, and the fixing strips 68 have slots 681. Raised strips 671 are fixedly connected to both the upper and lower sides of the filter element 67, and the raised strips 671 are compatible with the slots 681. The filter element 67 is detachably connected inside the filter box 63, facilitating regular cleaning or replacement, simplifying maintenance, and reducing operating costs. Furthermore, the combination of the slots 681 and the raised strips 671 allows for filter element 67 replacement without stopping the machine, saving time and effort.

[0029] Further refining the design, an extension frame 65 is fixedly connected to one side of the filter box 63. The lateral width of the inner diameter of the extension frame 65 is greater than the width of the filter element 67, and the vertical height of the extension frame 65 is adapted to the filter element 67. Supports 66 are fixedly connected to both sides of the extension frame 65, and a groove 661 is provided on the top of the support 66. An auxiliary component 64 is placed on the extension frame 65, with its bottom located within the groove 661. The extension frame 65 provides a buffer transition space for the filter element 67, facilitating its insertion into the filter box 63 from the outside and preventing it from getting stuck directly at the entrance of the filter box 63. The inner diameter of the extension frame 65 is wider than the width of the filter element 67 to facilitate the insertion of the tail end of the filter element 67 into the filter box 63, while also preventing the filter element 67 from getting stuck due to improper operation. The groove 661 provides a fixed storage position for the auxiliary component 64, preventing it from slipping and being lost, and making it easy to access.

[0030] Further refining the design, the auxiliary component 64 includes a long rod with a handle 641 fixedly connected to it. Connecting rods 642 are fixedly connected to both ends of the long rod, and a push plate 643 is fixedly connected to the end of each connecting rod 642 away from the long rod. The push plate 643 is used to completely push the filter element 67 into the filter box 63, and it is compatible with the groove 661. The push plate 643 is used to completely push the filter element 67 into the filter box 63, enabling quick and complete installation of the filter element 67 and improving replacement efficiency. The handle 641 provides a comfortable point of force application, making operation easier. Two push plates 643 are provided to evenly distribute the pushing force at both ends of the filter element 67, preventing it from tilting or getting stuck. When not in use, the push plate 643 can be placed on the support 66, positioning it within the groove 661. The inner diameter of the extension frame 65 is compatible with the push plate 643 to prevent excessive sliding of the filter element 67, ensuring a one-time installation.
