Description

Technical Field

[0001] This utility model relates to a punching device, specifically a punching device for removing burrs from blister boxes, and belongs to the field of blister box processing technology. Background Technology

[0002] Blister boxes are widely used in the packaging industry, and their production is typically completed using blister forming machines. During processing, the plastic sheet is first heated and softened, then shaped and set at a forming station, and subsequently conveyed as a semi-finished product via a chain conveyor. Afterwards, a punching machine cuts the material, removing excess material to give the product an independent shape for easy transport and use. As the cutting blades are used over time, their sharpness gradually decreases, resulting in less clean cuts and burrs during punching, thus requiring blade replacement.

[0003] Chinese Patent Publication CN222328474U discloses a punching device for an easily adjustable blister shell. This device uses a locking block inserted from bottom to top into a sliding groove. During movement, the locking block presses against the inclined surface of a limiting block, causing the limiting block to move outwards until the locking groove on the side of the locking block and the limiting block reach the same horizontal height. Under the action of a self-locking spring, the limiting block resets and engages with the locking block, fixing the positions of the locking block and the cutter. Compared to existing technologies, this self-locking reset method for locking and positioning the punching tool is simple and convenient, allowing for quick installation of the punching tool.

[0004] The cylinder in the above-mentioned patented technology has a fixed stroke for driving the punching die. Different punching dies have different thicknesses. If the height of the punching die is insufficient, it may not be able to apply enough pressure to complete the punching when pressing down. Therefore, it is necessary to add a pad to adapt to the cylinder stroke, which is inconvenient to use.

[0005] In the aforementioned patented technology, the cutter is fixed to the locking block. After the limiting block releases its restraint on the locking block, the locking block falls directly downwards under the influence of gravity, posing a certain degree of danger. Therefore, a punching and cutting device for removing burrs from blister packs is proposed here. Utility Model Content

[0006] This utility model proposes a punching and cutting device for removing burrs from blister boxes. The height of the punching and cutting mold can be adjusted without the need for a pad, which improves the ease of operation. At the same time, the cutter will not fall directly after disassembly, avoiding the safety hazards caused by falling due to gravity.

[0007] This utility model is achieved through the following technical solution: a punching device for removing burrs from blister boxes, including a workbench, the workbench including a support plate, a plurality of support legs fixed on the bottom surface of the support plate, and a fixing cylinder fixed on the top surface of the support plate.

[0008] The workbench is equipped with a punching assembly, which includes a top plate. A cylinder is mounted on the top of the top plate. The output end of the cylinder passes through the top plate and is fixed to a fixing plate. The bottom surface of the top plate is fixed to the top of the mounting shell.

[0009] The punching assembly is provided with a punching die, which includes an upper die and a lower die. The top surface of the upper die is fixed to a fixed plate. A slot is provided on the upper die, and a card plate is slidably connected in the slot. A cutter is fixed on the card plate, and the card plate is fixed to the slot by bolts.

[0010] The workbench is equipped with a lifting mechanism for raising and lowering the punching assembly. The lifting mechanism includes a mounting shell and a fixed cylinder. A bearing seat is fixed to the bottom of the mounting shell, and a threaded block is fixed to the top of the fixed cylinder. A lead screw is threaded onto the threaded block, and the lead screw is rotatably connected to the bearing seat. A worm gear is fixed to the upper end of the lead screw. A worm is rotatably connected to the mounting shell, and the worm is rotatably connected to the mounting shell through a bearing. The worm meshes with the worm wheel.

[0011] The lifting mechanism also includes a drive assembly for driving the worm gear. The drive assembly includes a rotating handle, which is fixed to one end of the worm gear extending outside the mounting housing. An anti-slip sleeve is fixedly fitted on the rotating handle.

[0012] The lifting mechanism also includes a guide assembly for guiding the top plate. The guide assembly includes a guide cylinder, which is fixed to the bottom surface of the top plate. A guide rod is slidably connected inside the guide cylinder, and the bottom of the guide rod is fixed to the support plate.

[0013] This utility model provides a punching and cutting device for removing burrs from blister packs, which has the following beneficial effects:

[0014] 1. This punching and cutting equipment for removing burrs from blister packs can drive a worm gear to rotate by turning the handle. The rotating worm gear will drive the worm wheel and lead screw to rotate. The rotating lead screw will rotate in the threaded block, thereby causing the mounting shell to move relative to the fixed cylinder. This allows for adjustment of the height of the top plate, cylinder, fixed plate, and upper mold. By adjusting the height of the upper mold, no shim plate is needed, improving the ease of operation. At the same time, the cutter is limited by the slot after disassembly, preventing it from falling directly and avoiding the safety hazards caused by falling due to gravity.

[0028] Please see Figures 1-4 The present invention proposes the following implementation scheme: a punching device for removing burrs from blister boxes, including a workbench 1, the workbench 1 including a support plate 101, a plurality of support legs 102 fixed on the bottom surface of the support plate 101, and a fixing cylinder 202 fixed on the top surface of the support plate 101.

[0029] Please refer to this carefully. Figure 1 and Figure 4 The workbench 1 is equipped with a punching assembly 3, which includes a top plate 301. A cylinder 302 is installed on the top of the top plate 301. The output end of the cylinder 302 passes through the top plate 301. A fixing plate 303 is fixed to the output end of the cylinder 302. When the cylinder 302 is started, it will drive the fixing plate 303 to move. The bottom surface of the top plate 301 is fixed to the top of the mounting shell 201.

[0030] Please refer to this carefully. Figure 1 and Figure 2 The punching assembly 3 is provided with a punching die 4, which includes an upper die 401 and a lower die 405. The lower die 405 is installed on the top surface of the support plate 101, and the top surface of the upper die 401 is fixed to the fixing plate 303. The upper die 401 is provided with a slot 402. The movement of the fixing plate 303 will drive the upper die 401, the slot 403, and the cutter 404 to move, thereby completing the punching.

[0031] Please refer to this carefully. Figure 2 A card plate 403 is slidably connected inside the card slot 402. A cutter 404 is fixed on the card plate 403. The card plate 403 is fixed to the card slot 402 by bolts. The card slot 402 and the card plate 403 can limit the cutter 404 and prevent the cutter 404 from falling directly after disassembly.

[0032] Please refer to this carefully. Figure 1 and Figure 3 The workbench 1 is provided with a lifting mechanism 2 for lifting the punching assembly 3. The lifting mechanism 2 includes a mounting shell 201 and a fixed cylinder 202. A bearing seat 203 is fixed at the bottom of the mounting shell 201, and a threaded block 204 is fixed at the top of the fixed cylinder 202.

[0033] A lead screw 205 is threaded onto the threaded block 204. The lead screw 205 is rotatably connected to the bearing housing 203. A worm wheel 206 is fixed to the upper end of the lead screw 205. A worm 207 is rotatably connected to the mounting housing 201. The worm 207 is rotatably connected to the mounting housing 201 through a bearing. The worm 207 meshes with the worm wheel 206.

[0034] The lifting mechanism 2 also includes a drive assembly 208 for driving the worm gear 207. The drive assembly 208 includes a rotating handle 2081, which is fixed to one end of the worm gear 207 that extends outside the mounting housing 201. An anti-slip sleeve 2082 is fixedly fitted on the rotating handle 2081.

[0035] The lifting mechanism 2 also includes a guide assembly 209 for guiding the top plate 301. The guide assembly 209 includes a guide cylinder 2091, which is fixed to the bottom surface of the top plate 301. A guide rod 2092 is slidably connected inside the guide cylinder 2091, and the bottom of the guide rod 2092 is fixed to the support plate 101.

[0036] Working principle: When the height of the top plate 301 needs to be adjusted, rotate the anti-slip sleeve 2082 and the rotating handle 2081. Rotating the handle 2081 will drive the worm gear 207 to rotate, which will drive the worm wheel 206 and the lead screw 205 to rotate. The lead screw 205 will rotate within the threaded block 204, thereby causing the mounting shell 201 to move relative to the fixed cylinder 202. This will adjust the height of the top plate 301, cylinder 302, fixed plate 303, and upper die 401. As a result, the upper die 401 can apply sufficient pressure to complete the punching when it is pressed down. By adjusting the height of the upper die 401, there is no need to use a shim plate, which improves the convenience of operation. At the same time, the cutter 404 is limited by the slot 402 after disassembly and will not fall directly, avoiding the safety hazards caused by falling due to gravity.
