Technical Field
[0001] This utility model relates to the field of wood processing technology, and in particular to a wood cutting waste collection device. Background Technology
[0002] In the production of existing wood products, wood needs to be cut using cutting equipment to cut it into suitable sizes and shapes. Most existing cutting devices involve manually placing the wood on a workbench and cutting it with a saw. This process generates a lot of waste, which is sometimes removed by a suction fan. However, this only tilts the floating waste, leaving debris on the workbench surface and affecting its cleanliness. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies where residual debris on the workbench surface is difficult to clean, and to propose a wood cutting waste collection device.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A wood cutting waste collection device is designed, including a collection box. A top frame is fixedly installed on the upper surface of the collection box. A lead screw is installed on the top of the top frame via a motor. A lifting block is threaded on the outer side of the lead screw. A guide rod is movably inserted through one side of the lifting block. The upper end of the guide rod is fixedly connected to the top of the top frame. A connecting frame is fixedly installed on the lower end of the lifting block. A brush plate is connected to the connecting frame via a motor. A worktable is fixedly installed inside the collection box. The worktable has a cutting groove and a material discharge hole.
[0006] Preferably, the workbench is circular in shape, with a gap between its outer edge and the inner wall of the collection box.
[0007] Preferably, the rotation center axis of the brush plate coincides with the center axis of the worktable.
[0008] Preferably, the length direction of the discharge hole is parallel to the length direction of the brush plate, the length of the brush plate is greater than the radius of the worktable, and the length of the discharge hole is less than the radius of the worktable.
[0009] Preferably, a sealing plate is hinged to one side of the collection box.
[0010] Preferably, the height of the upper end of the sealing plate is flush with the height of the upper surface of the worktable.
[0011] Preferably, a base plate is movably installed on the bottom inner side of the collection box, and a connecting block is fixedly installed on the lower surface of the base plate. A movable cavity is opened in the bottom of the collection box, and the lower end of the connecting block extends into the movable cavity and is connected to a spring. The lower end of the spring is fixedly connected to the bottom wall of the movable cavity. A foot rod is fixedly connected to one side of the connecting block.

[0019] 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.
[0020] Example 1: Refer to Figure 1-4A wood cutting waste collection device includes a collection box 1. A top frame 2 is fixedly installed on the upper surface of the collection box 1. A lead screw 3 is mounted on the top of the top frame 2 via a motor. The motor drives the lead screw 3 to rotate. The lead screw 3 is vertically positioned, and a lifting block 5 is threaded onto the outer side of the lead screw 3. The rotation of the lead screw 3 causes the lifting block 5 to move up and down. A guide rod 4 is movably inserted through one side of the lifting block 5. The upper end of the guide rod 4 is fixedly connected to the top of the top frame 2. The guide rod 4 works with the lead screw 3 to maintain the stability of the up and down movement of the lifting block 5. A connecting frame 6 is fixedly installed at the lower end of the lifting block 5. The up and down movement of the lifting block 5 causes the connecting frame 6 to move up and down. A brush plate 7 is connected to the connecting frame 6 via a motor. The up and down movement of the connecting frame 6 causes the brush plate 7 to move up and down. The motor drives the brush plate 7 to rotate.
[0021] A workbench 8, which is circular in shape, is fixedly installed inside the collection box 1. Wood is placed on the upper surface of the workbench 8, and a cutter is installed on the top frame 2 to cut the wood. There is a gap between the outer edge of the workbench 8 and the inner wall of the collection box 1, which allows the waste chips generated during cutting to fall and be collected. The rotation axis of the brush plate 7 coincides with the central axis of the workbench 8. When the motor drives the brush plate 7 to rotate, the brush plate 7 can thoroughly clean the debris on the upper surface of the workbench 8.
[0022] The workbench 8 has a cutting groove 9 and a discharge hole 10 inside. The cutting groove 9 provides cutting space for the top cutter, preventing it from cutting into the workbench 8. The length of the discharge hole 10 is parallel to the length of the brush plate 7. The length of the brush plate 7 is greater than the radius of the workbench 8, and the length of the discharge hole 10 is less than the radius of the workbench 8. When the brush plate 7 is cleaning debris on the workbench 8, the debris moves with the rotation of the brush plate 7. When the brush plate 7 rotates just above the discharge hole 10, the debris falls downward through the discharge hole 10, keeping the surface of the workbench 8 clean. Furthermore, since the cutter is located at the top, there is no danger even if the worker wipes the surface of the workbench 8 by hand.
[0023] A sealing plate 18 is hinged to one side of the collection box 1. The upper part of the sealing plate 18 is flush with the upper surface of the workbench 8. The worker stands outside the sealing plate 18, and its height allows for easy access to the wood. The other sides of the collection box 1 are higher than the sealing plate 18, providing protection against external debris from interfering with the cutting process and preventing debris from flying out. Since the cutting blade is designed for top-down cutting, it generates a large amount of debris. To prevent debris from flying out, the height of the other sides of the collection box 1 can be further increased to be significantly higher than the sealing plate 18, or even connected to the top frame 2, leaving only space above the sealing plate 18 for easy access to the wood. This effectively prevents debris from flying out.
[0024] Working Principle: During operation, this wood cutting waste collection device places the wood on the upper surface of the worktable 8, adjusts the position of the wood, and uses an external lifting device to move the cutter downwards to cut the wood. After cutting, the cutting device moves the cutter upwards to remove the wood. This process is repeated. When there is a lot of waste on the upper surface of the worktable 8, the motor is started to rotate the lead screw 3. The rotation of the lead screw 3 moves the lifting block 5 downwards, which in turn moves the brush plate 7 downwards through the connecting frame 6, bringing the brush plate 7 into contact with the upper surface of the worktable 8. The motor is then started to rotate the brush plate 7, which cleans the waste on the upper surface of the worktable 8. The cleaned waste falls through the discharge hole 10. After cleaning, the motor driving the brush plate 7 is turned off, and the motor is started again to rotate the lead screw 3, which moves the brush plate 7 upwards. This process does not affect subsequent cutting work on the worktable and keeps the worktable clean.
[0025] Example 2: In Example 1, because the positions of the workbench 8, cutting groove 9, and discharge hole 10 are fixed, wood chips can only fall through the gaps between the cutting groove 9, discharge hole 10, and the workbench 8 and the collection box 1. Therefore, the wood chips falling into the collection box 1 may be uneven, and other spaces inside the box cannot be effectively utilized. Therefore, this example is proposed. (Refer to...) Figure 1-3In another preferred embodiment of this utility model, based on embodiment 1, a bottom plate 11 is movably arranged on the bottom of the inner side of the collection box 1. A connecting block 15 is fixedly installed on the lower surface of the bottom plate 11. A movable cavity 14 is opened in the bottom of the collection box 1. The lower end of the connecting block 15 extends into the movable cavity 14 and is connected to a spring 16. The lower end of the spring 16 is fixedly connected to the bottom wall of the movable cavity 14. Under the elastic force of the spring 16, the connecting block 15 will always be at the top of the inner side of the movable cavity 14. At this time, the height of the bottom plate 11 is at its highest state. A foot rod 17 is fixedly connected to one side of the connecting block 15. The foot rod 17 is movably arranged in the bottom of the workbench 8 and its outer end extends to the outside of the collection box 1. When the worker steps on the foot rod 17, the foot rod 17 can drive the connecting block 14 to move downward, so that the spring 16 is compressed and the bottom plate 11 will also move downward.
[0026] A protruding strip 12 is fixedly installed on the side wall of the collection box 1, and a baffle 13 is fixedly installed on the upper surface of the bottom plate 11. The side of the baffle 13 contacts the side of the protruding strip 12. When the bottom plate 11 moves up and down, it will drive the baffle 13 to move up and down. The baffle 13 always keeps in contact with the protruding strip 12 when it moves up and down, so that the wood chips cannot fall below the bottom plate 11.
[0027] Once some debris has been collected in collection bin 1, the worker steps on pedal 17. Pedal 17 causes connecting block 15 to move downwards, compressing spring 16. Simultaneously, connecting block 15 causes base plate 11 to move downwards. When the worker releases pedal 17, spring 16 quickly rebounds, causing base plate 11 to move upwards rapidly via connecting block 15. This rapid upward movement of base plate 11 vibrates the debris in the bin, ensuring a more even distribution of debris on top of base plate 11, preventing unevenness. The worker can repeat stepping on pedal 17 as needed to effectively spread the debris evenly and compact it, reducing the space occupied by the debris and allowing for a larger amount of debris to be collected each time.
[0028] 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.
