Description

Technical Field

[0001] The invention belongs to the technical field of cutting machines, in particular to a plate cutting machine. Background Art

[0002] A sheet metal cutting machine is a machine used to cut and process sheets of wood. It is widely used in woodworking, furniture manufacturing and other industries. The price of a sheet metal cutting machine varies depending on factors such as brand, model, configuration and performance, ranging from tens of yuan to hundreds of thousands of yuan. Specifically, some basic, small sheet metal cutting machines, such as manual or semi-automatic equipment, may be relatively cheap and suitable for small processing companies or individuals. For example, some simple woodworking engraving machines or cutting machines may cost between tens of yuan and hundreds of yuan, while mid-to-high-end, fully automatic sheet metal cutting machines are relatively expensive, but have higher processing accuracy and efficiency, and are suitable for large processing companies or scenarios requiring high-precision processing. These devices may be equipped with advanced CNC systems, multi-axis control, automatic loading and unloading and other functions, and the price may reach tens of thousands or even hundreds of thousands of yuan.

When the brush plate is not under force, it will be driven by the elasticity of the spring itself to reset, so that when passing the pressure fence plate, it will repeatedly translate up and down to pass the material;

[0018] The present invention enables the magnetic plate on the screw to move horizontally under the blocking limit of the inner wall at one end of the cutting machine body. The translated magnetic plate will naturally drive the metal push plate above to translate through magnetic attraction, and the passively translated metal push plate will pass through the T-shaped slider connected to the T-shaped slide groove to play a role of limiting and guiding, so that the metal push plate that is flush with the double-layer moving bed and passively translates can push the cut sheet material and unload it from the cutting machine body without manual pushing operation, thus avoiding potential dangers during manual operation.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 9As shown, the present invention provides a plate cutting machine, including a cutting machine body 1, a lower chip fence groove is opened on the top side wall of the cutting machine body 1, a chip discharge plug 13 is passed through and tightly clamped on the bottom side wall of the cutting machine body 1, a cutter 11 is fixedly connected to the outer wall of one end of the cutting machine body 1 near the top, a double-layer movable bed 12 for placing a limited plate is fixedly connected to the outer wall of one end of the cutting machine body 1 near the bottom, a cleaning part 2 is provided on the cutting machine body 1, and the cleaning part 2 includes a fixedly connected There are two exhaust fans 21 on the inner wall of the bottom end side of the cutting machine body 1, and a U-shaped dustproof net 22 is fixedly connected to the inner wall of the bottom end side of the cutting machine body 1. A wind wheel rod 23 is provided above the U-shaped dustproof net 22. Both sides of the wind wheel rod 23 are movably sleeved with sleeve rods 24. The top ends of the two sleeve rods 24 are fixedly connected to the inner wall of the top end of the cutting machine body 1. A sweeping structure for cleaning the surface of the lower chip fence groove is provided on one end of the wind wheel rod 23, and a pushing structure for unloading the sheet material is also provided on the sweeping structure.

[0033] The above scheme is adopted: by starting the exhaust fan 21 in the cutting machine body 1, the wood chips on the surface of the lower chip fence groove are sucked through the U-shaped dustproof net 22, and the negative pressure suction force generated by the exhaust fan 21 can drive the wind wheel rod 23 to rotate in a positioning manner in the two sleeve rods 24. The rotating wind wheel rod 23 indirectly drives the rectangular groove plate 27 and the slide rod 28 to perform horizontal reciprocating motion under the auxiliary limit of the sleeve plate 29, so that the two sets of brushes 231 and a set of brush plates 232 connected and installed can be driven to sweep the surface of the lower chip fence groove, and the wood chips on the surface that are not easily pulled out by the exhaust fan 21 are cleaned. A section of the plate body at the top of a set of brush plates 232 is passively subjected to multiple pressures of the pressing fence plate 234. The sudden pressure can impact the inner wall of the lower chip fence groove to prevent some smaller sheets from blocking the lower chip fence groove. At the same time, the passively translated rectangular slot plate 27 can also synchronously drive the telescopic plate 235 to translate, thereby pulling the tooth plate in the meshing assembly 236 to drive the spur gear and screw 237 to rotate, thereby driving the magnetic plate 238 on the screw 237 to move horizontally under the blocking limit of the inner wall of one end of the cutting machine body 1. The translated magnetic plate 238 will naturally drive the metal push plate 239 above to translate by magnetic attraction, so that the metal push plate 239 that is flush with the double-layer moving bed 12 and passively translates can push the cut sheet material and unload it from the cutting machine body 1.

[0034] The flat sweeping structure includes a turntable 25 fixedly connected to one end of the wind wheel rod 23, and the rod body of the wind wheel rod 23 is specifically connected to the side wall of one end of the cutting machine body 1 for rotation. A limited rotating handle 26 is fixedly connected to the side wall of one end of the turntable 25, and a rectangular slot plate 27 is slidably connected to the limited rotating handle 26. A sliding rod 28 is fixedly connected to the outer wall of one end of the rectangular slot plate 27, and a sleeve plate 29 is slidably connected to the rod body of the sliding rod 28. One end plate body of the sleeve plate 29 is fixedly connected to the side wall of one end of the cutting machine body 1, and a T-shaped slot plate 230 is also fixedly connected to the rod body of the sliding rod 28. A plurality of brushes 231 are fixedly connected to the outer walls on both sides of the bottom end of the T-shaped slot plate 230, and a plurality of brush plates 232 are also slidably connected to the outer wall at the center position of the bottom end of the T-shaped slot plate 230, and each brush plate 232 is made of natural rubber material.

[0035] The above scheme is adopted: the negative pressure suction force generated by the exhaust fan 21 can drive the wind wheel rod 23 to rotate in a positioned manner within the two sleeve rods 24, thereby the rotating wind wheel rod 23 drives the turntable 25 and the limit handle 26 to rotate synchronously, and the limit handle 26 in the rotating state will slide and rotate on the inner wall of the rectangular slot plate 27, thereby driving the rectangular slot plate 27 and the slide bar 28 to perform horizontal reciprocating motion under the auxiliary limit of the sleeve plate 29, and the horizontally moving slide bar 28 will drive the T-shaped slot plate 230 to translate synchronously, thereby driving the two sets of brushes 231 and a set of brush plates 232 connected and installed to slide and sweep the surface of the lower chip fence groove, and clean the wood chips on the surface that are not easily pulled out by the exhaust fan 21, so that the passive reciprocating sweeping can successfully discharge the wood chips into the lower chip fence groove.

[0036] A spring 233 is fixedly connected to the side wall of each brush plate 232, and the top of each spring 233 is fixedly connected to the bottom outer wall of the T-slot plate 230. A pressure railing plate 234 is slidably connected to the bottom inner wall of the T-slot plate 230. The plates on both sides of one end of the pressure railing plate 234 are fixedly connected to the outer wall of the cutting machine body 1. The top section of each brush plate 232 can be intermittently slidably connected to the plate body of the pressure railing plate 234.

[0037] The above scheme is adopted: during the process of passive translation of a group of brush plates 232, the T-slot plate 230 will also translate through the pressure fence plate 234, so that a section of the plate body at the top of a group of brush plates 232 is passively subjected to multiple sudden pressures of the pressure fence plate 234, and a group of brush plates 232 will move downward under the force, thereby synchronously stretching the spring 233 on the side wall, causing it to deform and move downward, and then it can impact the inner wall of the lower chip fence groove to prevent some smaller sheets from clogging the lower chip fence groove. When the brush plate 232 is not under force, it will be driven to reset by the elasticity of the spring 233 itself, thereby repeatedly translating up and down to pass the material when passing through the pressure fence plate 234.

[0038] A telescopic plate 235 is fixedly connected to the outer wall at the other end of the rectangular slot plate 27, and a meshing assembly 236 is fixedly connected to the other end of the telescopic plate 235. The meshing assembly 236 is specifically composed of a spur gear and a toothed plate meshingly connected thereto. A screw rod 237 is fixedly connected to the outer wall at one end of the spur gear, and the rod body of the screw rod 237 is rotatably connected to one end of the cutting machine body 1. An L-shaped protective plate box 2361 is movably sleeved on the rod body of the screw rod 237, and the telescopic plate 235 and one end of the L-shaped protective plate box 2361 are slidably connected to each other, and one end plate of the L-shaped protective plate box 2361 is fixedly connected to the outer wall at one end of the cutting machine body 1.

[0039] The above solution is adopted: the passively translated rectangular slot plate 27 can also synchronously drive the telescopic plate 235 to translate, thereby pulling the tooth plate in the meshing assembly 236, thereby driving the spur gear confined in the L-shaped protective plate box 2361 to rotate, and the rotating spur gear will drive the screw 237 to rotate.

[0040] A magnetic plate 238 is threadedly connected to the rod body of the screw rod 237, and the outer wall of one end of the magnetic plate 238 is slidably connected to the inner wall of the cutting machine body 1. The top of the magnetic plate 238 is magnetically connected to a metal push plate 239, and the bottom outer wall of the metal push plate 239 is slidably connected to the top outer wall of the lower chip fence groove. A T-shaped slider 240 is also fixedly connected to the bottom side wall of the metal push plate 239, and a T-shaped groove 241 that can be slidably engaged with the T-shaped slider 240 is also provided on the top side wall of the cutting machine body 1.

[0041] The above scheme is adopted: the magnetic plate 238 on the screw 237 moves horizontally under the blocking limit of the inner wall at one end of the cutting machine body 1, and the translated magnetic plate 238 will naturally drive the metal push plate 239 above to translate by magnetic attraction, and the passively translated metal push plate 239 will pass through the T-shaped slider 240 connected to the T-shaped slide groove 241, which plays a role of limiting guide, so that the metal push plate 239 that is flush with the double-layer movable bed 12 and passively translates can push the cut sheet material and unload it from the cutting machine body 1 without manual pushing operation, thus avoiding potential dangers during manual operation.

[0042] One point that needs to be added is that the operation of the cutting machine body 1, the cutter 11, and the double-layer moving bed 12 are all existing technologies, and the specific operation implementation process will not be described in detail here.

[0043] The working principle and use process of the present invention are as follows: by starting the exhaust fan 21 in the cutting machine body 1, the wood chips on the surface of the lower chip fence groove are sucked through the U-shaped dustproof net 22, and the negative pressure suction force generated by the exhaust fan 21 can drive the wind wheel rod 23 to rotate in a positioning manner in the two sleeve rods 24, so that the rotating wind wheel rod 23 drives the turntable 25 and the limit handle 26 to rotate synchronously, and the limit handle 26 in the rotating state will slide and rotate on the inner wall of the rectangular slot plate 27, thereby driving the rectangular slot plate 27 and the slide bar 28 to perform horizontal reciprocating motion under the auxiliary limit of the sleeve plate 29, and the horizontally moving slide bar 28 will drive the T-shaped slot plate 230 to translate synchronously, so that the two sets of brushes 231 and a set of brush plates 232 installed in connection can be driven to fit the sliding and level sweeping lower chip fence. The surface of the groove is cleaned to clean the wood chips on its surface that are not easily pulled out by the exhaust fan 21, so that the passive reciprocating sweeping can successfully discharge the materials into the lower chip fence groove, and in the process of a group of brush plates 232 passively moving horizontally, the T-shaped slot plate 230 will also move horizontally through the pressure fence plate 234, so that a section of the plate body at the top of a group of brush plates 232 is passively pressed by the pressure fence plate 234 for many times, and a group of brush plates 232 will move downward under the force, thereby synchronously stretching the spring 233 on the side wall to cause it to deform and move downward, and then it can impact the inner wall of the bar groove of the lower chip fence groove to prevent some smaller plates from blocking the lower chip fence groove, and the brush plate 232 will be reset by the elasticity of the spring 233 itself when it is not under force, so that it will repeatedly move up and down to pass the materials when passing through the pressure fence plate 234;

[0044] At the same time, the passively translated rectangular slot plate 27 can also synchronously drive the telescopic plate 235 to translate, thereby pulling the toothed plate in the meshing assembly 236, thereby driving the spur gear limited in the L-shaped protective plate box 2361 to rotate, and the rotating spur gear will drive the screw 237 to rotate, thereby driving the magnetic plate 238 on the screw 237 to move horizontally under the barrier limit of the inner wall at one end of the cutting machine body 1, and the translated magnetic plate 238 will naturally drive the metal push plate 239 above to translate by magnetic attraction, and the passively translated metal push plate 239 will pass through the connection to the T-shaped slide 2 The T-shaped slider 240 in 41 plays the role of limiting and guiding, so that the metal push plate 239 that is flush with the double-layer movable bed 12 and passively translates can push the cut sheet material and unload it from the cutting machine body 1. The existence of the telescopic plate 235 can cause a certain time difference for the pushing operation of the metal push plate 239. The time during which the telescopic plate 235 is extended and retracted can make the metal push plate 239 that has completed pushing the material reset again before the next sheet material is cut and unloaded, thereby repeatedly pushing the material in a reciprocating trajectory without the need for manual pushing operations, thus avoiding potential dangers during manual operations.
