Description

Technical Field

[0001] This utility model relates to the field of plywood processing technology, and in particular to a plywood cutting device. Background Technology

[0002] According to the patent document with publication number CN222431015U, the patent document describes a process where plywood is placed on a workbench, and a sliding plate is driven by a threaded rod in a rotation control component. The sliding plate and clamping plate then stabilize and fix the plywood. Ball bearings push the plywood towards a collection box. Once it reaches the designated position, a hydraulic rod drives a moving block and an electric cutting blade to cut the surface of the plywood. The collection box collects the waste generated during cutting, and the collection box is removed from the workbench by a handle for centralized processing.

[0003] The patent document states that when the electric cutter cuts plywood, the waste chips will fly around in the direction of the electric cutter's rotation. The collection box can only collect part of the waste chips, and the rest of the waste chips will drift into the equipment and the environment, affecting the operation of the equipment and environmental hygiene. In addition, the electric cutter will heat up due to rotational friction during operation. If it is not cooled down in time, it will affect the cutting effect and the service life of the electric cutter. Utility Model Content

[0032] like Figures 1-11 As shown, a plywood cutting device includes a processing mechanism 1, a saw blade 2 on the upper side of the processing mechanism 1, and a cleaning mechanism 3.

[0033] In this embodiment: the cleaning mechanism 3 includes a first shield 301 located outside the saw blade 2, a second shield 302 fixed to the bottom of the first shield 301, the top of the first shield 301 fixedly connected to the moving plate 108, the second shield 302 being made of soft plastic, a collection frame 303 fixed to one side of the first shield 301, a gear 304 rotatably connected to the top of the collection frame 303, a discharge frame 305 slidably connected to the bottom of the collection frame 303, a filter plate 306 fixed to one side of the inside of the collection frame 303, a fan 307 fixed to one side of the filter plate 306, and a first rack 308 meshing with the bottom of the gear 304. On the other side, two connecting rods 309 are fixed, and a piston 313 is fixed to one end of each connecting rod 309. A water injection cylinder 312 is provided on the outer side of each piston 313. A fixing ring 314 is provided on the other side of each water injection cylinder 312. A sponge 315 is inserted into the side of each fixing ring 314 near the saw blade 2. Both fixing rings 314 are fixed to the outer side of the rotating shaft of the saw blade 2. The two water injection cylinders 312 are located on the front and rear sides of the saw blade 2, respectively. Both water injection cylinders 312 are fixedly connected to the first shield 301. A water inlet pipe gear 304 is fixed to the top of each water injection cylinder 312, and two second racks 310 mesh on one side of each gear. A device for... The scraper 311 removes debris from the filter plate 306. A fourth motor is fixedly installed at the input end of the gear 304. The first rack 308 is slidably connected to the top of the collection frame 303. The scraper 311 is located on the other side of the filter plate 306. The first shield 301 and the second shield 302 block the debris generated during the saw blade 2 cutting process. The blower 307 sucks the debris from the first shield 301 and the second shield 302 into the collection frame 303. The filter plate 306 intercepts the debris on its surface. The fourth motor drives the gear 304 to rotate clockwise. The gear 304 meshes with the first rack 308 and the two second racks 310, thereby causing the first rack to rotate clockwise. The first rack 308 moves to the other side, thereby driving the two connecting rods 309 to move to the other side. The two connecting rods 309 push the corresponding pistons 313 to slide inside the water injection cylinder 312, squeezing the water in the water injection cylinder 312 onto the sponge 315. The water-laden sponge 315 cools the saw blade 2. The two second racks 310 move downward, thereby driving the scraper 311 to move downward, scraping the waste on the filter plate 306 into the discharge frame 305. The fourth motor then drives the gear 304 to rotate counterclockwise, causing the first rack 308 and the two second racks 310 to respectively drive the two connecting rods 309 and the scraper 311 to reset, pulling the discharge frame 305 to one side to dump the collected waste.

[0034] In this embodiment: the processing mechanism 1 includes a base 101, a first sliding seat 102 slidably connected to the top of the base 101, a first lead screw 103 threadedly connected to the bottom of the first sliding seat 102, a support frame 104 fixed to the top of the base 101, a second sliding seat 105 slidably connected to the front side of the top of the support frame 104, a second lead screw 106 threadedly connected to the bottom of the second sliding seat 105, the first lead screw 103 rotatably connected to the top of the base 101, a first motor fixedly installed at the input end of the first lead screw 103, the second lead screw 106 rotatably connected to the top of the support frame 104, a second motor fixedly installed at the input end of the second lead screw 106, a first hydraulic cylinder 107 fixedly installed at the top of the second sliding seat 105, a moving plate 108 fixedly installed at the telescopic end of the first hydraulic cylinder 107, and the saw blade 2 rotates... The saw blade 2 is connected to the bottom of the moving plate 108. A third motor is fixedly installed at the input end of the shaft of the saw blade 2. Two pressure rods 109 are provided on the top of the first sliding seat 102. A second hydraulic cylinder 110 is fixedly installed on both sides of the pressure rod 109. The four second hydraulic cylinders 110 drive the corresponding two pressure rods 109 to move downward, thereby pressing the plywood. The first hydraulic cylinder 107 drives the moving plate 108 to move downward, thereby driving the saw blade 2 to move downward and contact the plywood. The third motor drives the shaft to rotate and drive the saw blade 2 to cut the plywood. The second motor drives the second lead screw 106 to drive the second sliding seat 105 and the saw blade 2 to move along both sides. The first motor drives the first lead screw 103 to drive the first sliding seat 102 and the plywood to move along the front and rear sides.

[0035] Working principle: The plywood to be cut is placed on top of the first sliding seat 102. The four second hydraulic cylinders 110 drive the corresponding two pressure rods 109 to move downward, thereby pressing the plywood. The first hydraulic cylinder 107 drives the moving plate 108 to move downward, thereby moving the saw blade 2 downward to contact the plywood. The moving plate 108 moves downward and simultaneously drives the cleaning mechanism 3 to move downward. The second shield 302 contacts and surrounds the part of the plywood that the saw blade 2 is cutting. The third motor drives the rotating shaft to rotate the saw blade 2 to cut the plywood. The second motor drives the second lead screw 106 to move the second sliding seat 105 and the saw blade 2 along both sides to cut. The four second hydraulic cylinders 110 drive the corresponding two pressure rods 109 to move upward, thereby releasing the two pressure rods 109 from pressing the plywood. The first motor drives the first lead screw 103 to move the first sliding seat 102 and the plywood along the front and rear sides to cut the next position of the plywood.

[0036] During the saw blade 2's cutting of plywood, the first shield 301 and the second shield 302 block the waste generated during the saw blade 2's cutting process. The blower 307 sucks the waste from the first shield 301 and the second shield 302 into the collection frame 303. The filter plate 306 intercepts the waste on its surface. The fourth motor drives the gear 304 to rotate clockwise. The gear 304 meshes with the first rack 308 and the two second racks 310. Consequently, the first rack 308 moves to the other side, thereby driving the two connecting rods 309 to move to the other side. The two connecting rods 309 push the corresponding pistons 313 to slide inside the water injection cylinder 312. Water is squeezed out of the water injection cylinder 312 onto the sponge 315. The rotating shaft drives the two fixed rings 314 and the two sponges 315 to rotate. The sponges 315 with water cool the saw blade 2. The two second racks 310 move downward, thereby driving the scraper 311 to move downward and scrape the waste on the filter plate 306 into the discharge frame 305. The fourth motor then drives the gear 304 to rotate counterclockwise, so that the first rack 308 and the two second racks 310 drive the two connecting rods 309 and the scraper 311 to reset respectively. After the plywood is processed, the discharge frame 305 is pulled out to one side to dump the collected waste. Water is then added to the water injection cylinder 312 through the water inlet pipe.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
