Description

Technical Field

[0001] This utility model relates to the technical field of placemat production equipment, and in particular to a fixed-length cutting device for producing placemats. Background Technology

[0002] The placemat slitting device is a key piece of automated equipment in the placemat manufacturing process. Its core function is to precisely cut the continuously conveyed placemat raw materials (such as plastic film, non-woven fabric, bamboo fiber rolls, etc.) according to preset length standards, transforming the rolls into individual placemat blanks that meet the specifications.

[0003] Currently, placemat length cutting devices have established a relatively mature basic architecture. The placemat raw materials are clamped on the raw material fixing plate. The cutting execution end mostly uses a cylinder to push the cutter or the raw material fixing plate for cutting. If the spacing needs to be adjusted, the screw needs to be manually turned and the shims added or removed. The process is cumbersome and the accuracy is difficult to guarantee. The clamping components are mostly simple clamping blocks.

[0004] Existing equipment has gradually revealed its core defects in actual production: the tool spacing adjustment is limited. The cutters of traditional equipment are mostly fixed or rely on manual fine-tuning, which makes it impossible to quickly and accurately adjust the tool spacing synchronously, and it takes a long time to switch production specifications; the clamping mechanism has defects. Existing clamping components are difficult to adapt to placemats of different sizes and thicknesses, and the clamping force cannot be flexibly adjusted. Utility Model Content

The limiting grooves 12 are all slidably connected. One end of the support block 6 is fixedly connected to the support frame 17. A second guide post 15 is connected through and fixedly connected to one side of the support frame 17. The outer ring of the second guide post 15 is connected through and slidably connected to the first fixing block 13 on the right side. One end of the second guide post 15 is fixedly connected to the connecting block. The connecting block is fixedly connected to the top of the support block 6. The other side of the support frame 17 is connected through and rotatably connected to the first lead screw 16. The outer ring of the first lead screw 16 is connected through and threaded to the first fixing block 13 on the left side. A nut pair is provided inside the first fixing block 13 on the left side. One end of the first lead screw 16 is fixedly connected to the handle for easy rotation by the operator. The other end of the first lead screw 16 is rotatably connected to the connecting block. The connecting block is fixedly connected to the top of the support block 6. A quick-release assembly is provided on one side of the top of the first fixing block 13. A fixing assembly is provided at the output end of the cylinder 4.

[0021] The quick-release assembly includes a second fixing block 21, the bottom of which is fixedly connected to the first fixing block 13. A fixing plate 22 is slidably connected to the top of the inner wall of the first fixing block 13, limiting the position of the limiting plate 11. Sliding posts 19 are slidably connected through both sides of one end of the second fixing block 21, with one end of each sliding post 19 slidably connected to the fixing plate 22. A first spring 20 is fitted onto one end of the outer ring of each sliding post 19. A first sliding plate 18 is slidably connected through and fixed to one end of the outer ring of each sliding post 19. A handle is fixedly connected to the other end of the sliding post 19 on the same side, facilitating the operator to pull the sliding post 19. The movable column 19 slides into the interior of the fixed plate 22 under the elastic force of the first spring 20, limiting the position of the fixed plate 22. One end of the first spring 20 is fixedly connected to the first sliding plate 18, and the other end of the first spring 20 is fixedly connected to the second fixed block 21. The fixing assembly includes a support platform 23. The bottom of the support platform 23 is fixedly connected to the output end of the cylinder 4. The cylinder 4 can drive the support platform 23 to rise and fall. A servo motor 14 is fixedly connected to one side of the support platform 23. A bidirectional threaded rod 24 is fixedly connected to the output end of the servo motor 14. When the servo motor 14 is started, it can drive the bidirectional threaded rod 24 to rotate. Both sides of the ring are threaded with sliders 25, which are slidably connected to the inside of the support platform 23. Each slider 25 has a nut pair inside. Both ends of the slider 25 are fixedly connected to fixed frames 26. Pressure plates 27 are slidably connected between the fixed frames 26 on the same side. Each pressure plate 27 has a handle fixedly connected to its top for easy lifting. Each fixed frame 26 has a second lead screw 28 threaded through and rotatably connected to its top. Each second lead screw 28 has a knob fixedly connected to its top for easy rotation. Second sliding plates 30 are slidably connected to the inner wall of each fixed frame 26. The second sliding plates 30 are connected to the outer ring of the second lead screw 28. All are threaded and connected. The interior of the second sliding plate 30 is provided with a nut pair. The bottom of the second sliding plate 30 is fixedly connected with a second spring 29, and one end of the second spring 29 is fixedly connected to the top of the pressure plate 27. The elastic force of the second spring 29 can be changed by squeezing the top of the second spring 29. The bottom two ends of the support plate 3 are both threaded and slidably connected with a first guide post 5. The first guide post 5 prevents the support platform 23 from shaking when the cylinder 4 drives the support platform 23 to slide. The bottom end of the connecting frame 9 is provided with a cutter 31. The cutter 31 is fixedly connected to the connecting frame 9 by bolts. The number of cutters 31 can be changed as needed.

[0022] Working principle: First, rotate the handle of the first lead screw 16. The first fixed block 13 on the left moves laterally along the first lead screw 16 through the internal nut pair. The first fixed block 13 on the right slides synchronously along the second guide post 15, driving the limit plate 11 to move as a whole. The limit groove 12 at the top of the limit plate 11 slides relative to the limit post 10 of the connecting frame 9, driving the sliding frame 8 to move along the fixed rod 7, thereby adjusting the spacing of the bottom cutter 31 of the connecting frame 9 until it meets the target placemat length. When it is necessary to replace a different limit plate 11, the operator pulls the handle of the sliding post 19 outward. The first sliding plate 18 compresses the first spring 20, and the sliding post 19 is pulled out from the fixed plate 22, releasing the limitation on the fixed plate 22. Slide the fixed plate 22 upward to release the limitation on the limit plate 11. At this time, the limit plate 11 can be slid out for replacement. Then, reset the fixed plate 22 and release the handle of the sliding post 19. The sliding post 19 resets under the reaction force of the first spring 20 and re-limits the fixed plate 22. Place the placemat material on the support platform 23, start the servo motor 14, and drive the bidirectional threaded rod 24 to rotate. Because the threads on both sides of the bidirectional threaded rod 24 are opposite, the sliders 25 on both sides move closer or further away from the support platform 23 through the internal nut pair, driving the fixed frame 26 and the pressure plate 27 to move until the distance between the pressure plates 27 matches the width of the placemat. Pull up the handle of the pressure plate 27, place the placemat material under the pressure plate 27, and release the pressure plate 27. The pressure plate 27 will then be limited by the force exerted by the second spring 29 on the pressure plate 27. Depending on the material and thickness of the placemat, turn the knob of the second screw 28. The second sliding plate 30 will rise and fall along the inner wall of the fixed frame 26 through the internal nut pair, squeezing the second spring 29, changing the elasticity of the second spring 29, and thus adjusting the clamping force of the pressure plate 27 on the placemat material. When cylinder 4 is activated, its output end pushes the support platform 23 upward. The first guide column 5 slides along the support plate 3 to prevent the support platform 23 from shaking. The placemat rises synchronously with the support platform 23 until it contacts the cutter 31 for cutting.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
