Description

Technical Field

[0001] This utility model relates to a sawdust collection device, belonging to the field of wood processing equipment. Background Technology

[0002] A planer is a linear motion machine tool that uses planing tools to plan the flat, grooved, or shaped surfaces of a workpiece. Planing tools are relatively simple, making it very suitable for processing wood products.

[0003] However, most traditional planers do not have a sawdust collection function, and a large amount of sawdust is often generated during the planing process. This sawdust is splashed on the workbench, the planks, and the ground, making it difficult for workers to clean up later.

[0004] CN202322235755.7 A woodworking workbench with an attached sawdust collection bin. By setting up the collection bin, most of the sawdust generated during template cutting can be collected, preventing sawdust from being blown around by the wind and flying onto the beam and slab template surface, thus saving workers the step of cleaning up the scattered sawdust.

[0005] The applicant argues that during actual use, due to the high-speed rotation of the planer blade, the planer blade still carries some wood chips, which then splatter onto the worktable as the planer blade rotates at high speed. Utility Model Content

[0006] The purpose of this invention is to provide a wood chip collection device that can effectively solve the above-mentioned problems.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] The device includes a worktable, on which a cutting blade is provided; a baffle plate is provided above the cutting blade, and the baffle plate is mounted on the worktable via a lifting device.

[0009] The workbench has material drop holes on both sides of the cutting blade.

[0010] Furthermore: the baffle plate includes an arc plate with an arc groove in the middle, and a first horizontal baffle is provided at the front and rear ends of the arc plate, the first horizontal baffle projecting onto the discharge hole.

[0011] Furthermore: a second horizontal baffle is provided on both sides of the arc plate, and the second horizontal baffle is integrally formed with the first horizontal baffle.

[0012] Furthermore: the lifting device includes a mounting block fixed to the upper end of the workbench, a motor is provided at the upper end of the mounting block, a screw is connected to the output end of the motor, limit rods are provided on both sides of the screw, a lifting block is threadedly connected to the screw, and the lifting block is slidably mounted on the limit rods; the lifting block is fixedly connected to the baffle plate through a connecting rod.

[0013] Furthermore, the workbench has a dust collection slit, and the dust collection slit is perpendicular to the projection of the cutting disc on the horizontal plane.

[0014] Furthermore, multiple baffles are evenly distributed in the discharge hole, and the discharge gaps are formed between the baffles.

[0015] The beneficial effects are:

[0016] Some of the wood chips produced during cutting will fly off with the high-speed rotating cutting blade. At this time, the baffle plate can cover the cutting blade to prevent wood chips from flying off. Meanwhile, some of the wood chips blocked by the baffle plate will fall directly into the discharge hole, and then fall directly into the discharge box in the lower part of the workbench.

[0017] In this device, the baffle plate is installed on the lifting device and is used to receive control from the lifting device to raise and lower relative to the cutting blade. The advantage of this design is that, during actual wood cutting, the wood has a certain thickness. When the wood is very thin, the cutting blade can be lowered by the lifting device, which lowers the horizontal height of the baffle plate. When the wood is cutting and wood chips are flying, the lower horizontal height of the baffle plate can reduce the travel distance of the flying chips, thereby blocking more wood chips. When the wood is very thick, the horizontal height of the baffle plate can affect the normal cutting of the wood. At this time, the horizontal height of the baffle plate can be adjusted by the lifting device. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] See Figure 1-3 This is one embodiment of a sawdust collection device according to the present invention.

[0029] It includes a worktable 1, on which a cutting blade 2 is provided; above the cutting blade 2, a baffle plate 3 is provided, and the baffle plate 3 is set on the worktable 1 via a lifting device 4;

[0030] The workbench 1 has material drop holes 6 on both sides of the cutting disc 2.

[0031] The workbench 1 of this device is located at the upper end of the workbench and serves as the work surface. The workbench also includes a box, and the discharge hole 6 is connected to the box. A discharge box can be installed in the box to collect wood chips.

[0032] When this device is in use, the wooden board slides on the workbench 1 and contacts the cutting blade 2. The cutting blade 2 cuts the wooden board, and some of the wood chips produced by cutting will fly off with the high-speed rotating cutting blade 2. At this time, the baffle plate 3 can cover the cutting blade 2 to prevent wood chips from flying off. At the same time, some of the wood chips blocked by the baffle plate 3 will fall directly into the discharge hole 6, and then fall directly into the discharge box in the lower end of the workbench 1 through the discharge hole 6.

[0033] In this device, the baffle plate 3 is installed on the lifting device 4 and is used to receive the control of the lifting device 4 to raise and lower relative to the cutting blade 2. The advantage of this setting is that when the wood is actually being cut, the wood has a certain thickness. When the wood is very thin, the cutting blade 2 can be lowered by the lifting device 4, which means lowering the horizontal height of the baffle plate 3. When the wood is being cut and wood chips are flying, the lower horizontal height of the baffle plate 3 can reduce the travel of the flying wood chips and achieve the effect of blocking more wood chips. When the wood is very thick, the horizontal height of the baffle plate 3 will affect the normal cutting of the wood. At this time, the horizontal height of the baffle plate 3 can be adjusted by the lifting device 4.

[0034] Meanwhile, in order to improve the material blocking efficiency of the baffle plate 3, the structure of the baffle plate 3 is optimized in this device;

[0035] The baffle plate 3 includes an arc plate 31 with an arc groove 32 in the middle. The diameter of the arc of the arc plate 31 is slightly larger than the diameter of the circle of the cutting blade 2. The arc groove 32 is provided in the arc plate 31. When the arc plate 31 is lowered to its lowest position, the arc of the arc plate 31 and the circle of the cutting blade 2 are concentric circles, which can perfectly fit the cutting blade 2 and block the wood chips.

[0036] The front and rear ends of the arc plate 31 are provided with a first horizontal baffle 33, and the orthographic projection of the first horizontal baffle 33 covers the material drop hole 6.

[0037] The purpose of the first horizontal baffle 33 in this device is to increase the blocking area in order to block the tilted and splashed wood chips. When the wood chips are thrown out by the cutting blade 2, some wood chips will be thrown out at an angle. At this time, the first horizontal baffle 33 can block them to prevent the wood chips from splashing further. At the same time, the blocked wood chips will fall into the discharge hole 6 and be collected directly in the discharge box through the discharge hole 6, thus ensuring the cleanliness of the upper surface of the workbench 1.

[0038] Because this device is designed to facilitate the processing of thick wooden boards, the arc length of the curved plate 31 is not long, equivalent to one-sixth of the arc length of the circle. Therefore, the curved plate 31 cannot cover the entire top of the cutting disc 2, and thus cannot block all the wood chips from flying. In order to increase the blocking area of ​​the curved plate 31, a second horizontal baffle 34 is provided on both sides of the curved plate 31. The second horizontal baffle 34 is integrally formed with the first horizontal baffle 33.

[0039] The second horizontal baffle 34 compensates for the shortcomings of the arc plate 31, covering the entire top of the cutting blade 2. When the cutting blade 2 throws out wood chips, the second horizontal baffle 34 can increase the blocking area, further improve the efficiency of wood chip blocking, and speed up wood chip collection.

[0040] The lifting device 4 of this device includes a mounting block 41 fixed on the upper end of the workbench 1. A motor 42 is provided on the upper end of the mounting block 41. A screw 43 is connected to the output end of the motor 42. Limiting rods 44 are provided on both sides of the screw 43. A lifting block 45 is threadedly connected to the screw 43, and the lifting block 45 is slidably mounted on the limiting rods 44. The lifting block 45 is fixedly connected to the baffle plate 3 through a connecting rod 46.

[0041] The specific working principle of the lifting device 4 is as follows: the motor 42 starts and drives the screw 43 to rotate. The lifting block 45, which is threadedly connected to the screw 43, rotates with the screw 43 and is limited by the upper limit rod 44 to achieve lifting. At the same time, the lifting block 45 drives the baffle plate 3 to lift through the connecting rod 46.

[0042] In this device, the baffle plate 3 is made of plastic, and the arc plate 31, the first horizontal baffle 33, and the second horizontal baffle 34 are integrally formed.

[0043] The workbench 1 has a dust collection slit 5, and the dust collection slit 5 is perpendicular to the projection of the cutting disc 2 on the horizontal plane.

[0044] The mortar drop joint 5 of this device allows as much wood dust as possible to fall into the collection box. After the template is cut, the worker can quickly sweep the small amount of debris on the workbench 1 into the collection box through the mortar drop joint 5.

[0045] Multiple baffles 7 are evenly distributed in the discharge hole 6, and the discharge gap is formed between the baffles 7.

[0046] In this device, the area of ​​the discharge hole 6 can be made very large in order to facilitate the discharge of more wood chips. However, if the area is large, the processed material may fall off. Considering that wood chips are very small objects, the applicant arranges multiple baffles 7 in the discharge hole 6 to form a smaller discharge gap and prevent the material from falling off.

[0047] Meanwhile, the stop bar 7 has a cylindrical structure, which makes it easy for sawdust to fall down. At the same time, the axis of the stop bar 7 is parallel to the direction of the wood board processing and pushing, so that the wood board can move smoothly above the stop bar 7.

[0048] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
