[0029] The utility model provides Figures 1 to 4 A plate cutting device is shown, comprising:

[0030] Processing table 1;

[0031] A cutting device 2 is provided on top of the processing table 1, and the cutting device 2 includes a support plate 201, a cutting chain 202 provided outside the support plate 201, and a driving device 203 for driving the cutting chain 202;

[0032] A fixing box 3 is fixed on the top of the processing table 1. The top of the fixing box 3 passes through the support plate 201 and extends upward. The inner cavity of the fixing box 3 is provided with a lifting assembly 4 for adjusting the height of the cutting device 2. A fixing frame 5 is fixed to the outside of the support plate 201. The opposite side of the fixing frame 5 is rotatably connected to a cutting roller 6 through a bearing. A driving motor 7 for driving the cutting roller 6 is fixed to the outside of the fixing frame 5.

[0033] A guide groove 8 is provided at the center of the right side of the processing table 1. A push plate 10 is movably provided in the inner cavity of the guide groove 8. A translation component 9 for moving the push plate 10 is provided at the bottom of the processing table 1.

[0034] By extending the length of the cutting device 2 and cutting the plate horizontally, it is avoided that a larger-sized cutting blade is needed when traditional circular cutting blades are used to cut wider plates, resulting in a large footprint and inconvenience in cutting. At the same time, a cutting roller 6 is added to cut the cut surface of the plate after cutting, remove burrs on the cut surface, and ensure the flatness of the cut surface, thereby avoiding secondary processing of the plate.

[0035] The lifting assembly 4 includes a connecting plate 41 movably arranged inside the fixed box 3, and a lifting screw 42 is threadedly connected to the center of the connecting plate 41. The lifting screw 42 rotates in the inner cavity of the fixed box 3 through a bearing. The top of the lifting screw 42 passes through the outside of the fixed box 3 and is fixed with a rotating handle 43. The four sides of the connecting plate 41 pass through the outside of the fixed box 3 and are fixedly connected to the support plate 201. The connecting plate 41 is driven to move up and down in the fixed box 3 by the lifting screw 42, and then the connecting plate 41 is used to drive the support plate 201 to adjust the height of the cutting equipment 2, so that the equipment can cut plates of different thicknesses.

[0036] The translation assembly 9 includes a movable plate 91 located at the bottom of the processing table 1, and a rack plate 92 is embedded in the bottom of the movable plate 91. A mounting frame 93 is fixed to the bottom of the processing table 1, and a servo motor 94 is fixed to the outside of the mounting frame 93. The output shaft of the servo motor 94 passes through the inner cavity of the mounting frame 93 and is fixed with a rotating shaft 95 that is rotatably connected to the inside of the mounting frame 93. A driving gear 96 is fixed to the outside of the rotating shaft 95, and the driving gear 96 is engaged with the rack plate 92. The push plate 10 is fixed to the end of the movable plate 91, and the rotating shaft 95 is driven to rotate by the servo motor 94. The driving gear 96 on the rotating shaft 95 is used to drive the rack plate 92 to translate, so that the movable plate 91 drives the push plate 10 to move horizontally, which is convenient for pushing the plate to be cut and facilitating rapid cutting processing.

[0037] Two rows of grooves are provided on the top of the processing table 1, and the inner cavity of the groove is rotatably connected to the support roller 11 through a bearing. The top of the support roller 11 extends to the top of the processing table 1. The setting of the support roller 11 facilitates the support of the plate and the movement of the plate on the processing table 1, which facilitates rapid cutting.

[0038] A fixed plate 12 is fixed to the upper end of one side of the push plate 10, and an adjusting screw 13 is threadedly connected to the center of the fixed plate 12. The bottom of the adjusting screw 13 is rotatably connected to an extrusion plate 14 through a bearing. The extrusion plate 14 fits the outer side of the push plate 10, and the rotation of the adjusting screw 13 drives the extrusion plate 14 to move up and down, which is convenient for clamping and fixing the plate to be cut, and cooperates with the support roller 11 to limit the plate to prevent the plate from shaking during cutting and transportation.

[0039] The bottom of the fixing frame 5 passes through the processing table 1 and extends downward. The outer side of the processing table 1 is threadedly connected with a limit bolt 15, and the limit bolt 15 fits the outer side of the fixing frame 5. The setting of the limit bolt 15 facilitates the limiting of the fixing frame 5 to ensure the stability of the fixing frame 5 and facilitates the relative stability of the cutting roller 6, guide rod 21 and cutting chain 202 on the fixing frame 5 to avoid unevenness on the surface of the plate after cutting.

[0040] Multiple groups of support frames 16 are fixed to the bottom of the processing table 1, and the movable plate 91 is located in the inner cavity of the support frame 16. Through the cooperation of the support frame 16, the movable plate 91 is conveniently supported to ensure that the movable plate 91 fits well on the bottom of the processing table 1, avoiding the movable plate 91 driving the push plate 10 to move up and down, causing the plate to be processed to shake.

[0041] Limiting grooves 17 are provided on the front and back of the movable plate 91. The inner cavity of the limiting groove 17 is slidably connected to the limiting block 18. The limiting block 18 is fixed to the inner cavity of a group of support frames 16. The limiting block 18 slides in the limiting groove 17 to limit the movable plate 91, thereby preventing the push plate 10 from colliding with the cutting chain 202 and causing damage to the cutting chain 202.

[0042] A slide groove 19 is provided on the side of the push plate 10, and a slider 20 is slidably connected to the inner cavity of the slide groove 19. One side of the slider 20 passes through the slide groove 19 and is fixed to the outer side of the extrusion plate 14. The slider 20 slides in the inner cavity of the slide groove 19, and the slider 20 is used to limit the stability of the extrusion plate 14, thereby ensuring the stability of the extrusion plate 14 in limiting the plate.

[0043] A guide rod 21 is fixed on the opposite side of the fixed frame 5, and the top of the guide rod 21 is flush with the top of the cutting chain 202. The setting of the guide rod 21 facilitates the isolation of the two groups of cut plates, ensuring that the upper plate will not be squeezed downward due to gravity, causing the cutting chain 202 to be stuck with the plate.

[0044] When in use, the handle 43 is rotated to drive the lifting screw 42 to rotate, and the height of the connecting plate 41 is adjusted. Then, the connecting plate 41 drives the support plate 201 to adjust the height of the cutting device 2. Then, the fixing frame 5 is fixed with the limit bolt 15. The plate to be cut is placed on the right side of the top of the processing table 1. Then, the adjusting screw 13 is rotated, and the plate is clamped and limited by the extrusion plate 14. The servo motor 94 is started, and the servo motor 94 drives the rotating shaft 95 to rotate. Then, the rotating shaft 95 drives the rack plate 92 to move forward through the driving gear 96. The plate is moved horizontally. Since the rack plate 92 is fixed on the fixed plate 12, the fixed plate 12 is translated at the bottom of the processing table 1. The movable plate 91 drives the push plate 10 to push the plate to the left, so that the plate moves on the support roller 11. At the same time, the driving device 203 of the cutting device 2 is started to drive the cutting chain 202, and the cutting chain 202 is used to cut the plate. Then the guide rod 21 guides and supports the divided plate. At the same time, the driving motor 7 drives the cutting roller 6 to rotate, and the cutting surface of the plate is cut to ensure that the cut surface is flat.
