Description

Technical Field

[0001] This utility model belongs to the technical field of packaging bag die-cutting equipment, and more specifically, it relates to a packaging bag die-cutting machine. Background Technology

[0002] Due to their low price and large capacity, plastic packaging bags are widely used in daily life. The production process of plastic bags requires die-cutting machines to process plastic raw materials into various types of bags. However, during production, the plastic bags need to be neatly arranged and then packaged. If this is done manually, the process is quite slow.

[0003] Patent CN222905038U discloses a packaging bag die-cutting machine, relating to the technical field of packaging bag die-cutting equipment. It includes a die-cutting table with multiple support columns fixed to its top, a top plate fixed to the top of the support columns, a lower die fixed inside the die-cutting table, an electric push rod fixed to the top of the top plate, an upper die fixedly connected to the output end of the electric push rod, and two springs at the bottom of the upper die. While this patent solves the problem of stacking bags, after stacking, the bags still need to be manually pulled by the pull ring to remove them from the device. Furthermore, during the upward movement of the die-cutting table, the cut bags are easily moved upwards by the springs, potentially damaging the film and making removal inconvenient.

[0004] To address the aforementioned technical problems, this application proposes a solution. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The film cutting mechanism and stacking mechanism of this utility model work together to quickly die-cut the film on the film roll. The die-cut film falls onto the film plate frame. As more and more film accumulates on the film plate frame, the drive device slowly rotates the lead screw to move the film plate frame downward. When the thickness of the die-cut film is consistent with the limit plate, the film plate frame continues to move downward. The telescopic device pushes the film that has fallen onto the template frame to the support platform for packaging.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings: The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0017] like Figures 1 to 6 As shown, a packaging bag die-cutting machine includes a support 2, a film cutting mechanism 1 fixedly connected to the top of the support 2, and a stacking mechanism 3 fixedly connected to the middle and lower parts of the support 2. Figure 4 As shown, the stacking mechanism 3 includes a middle layer plate 301 fixed in the middle of the support 2. The middle layer plate 301 is hollow in the middle, and four independent limiting plates 303 are fixedly connected around the hollow. Slide rods 302 are fixedly connected to both ends of the bottom side of one side of the middle layer plate 301. One end of the slide rods 302 is fixedly connected to the bottom of the support 2. Lead screws 305 are rotatably connected to both ends of the bottom side of the middle layer plate 301. One end of the lead screws 305 is rotatably connected to the bottom of the support 2. A membrane plate frame 304 is connected to the lead screws 305 and the slide rods 302. A synchronous pulley 308 is fixedly connected to the bottom end of the lead screw 305. A synchronous belt 307 is meshed with the synchronous pulley 308. A drive device 309 is fixedly connected to the bottom outside of the support 2. A synchronous pulley 3091 is fixedly connected to the rotating end of the drive device 309. The synchronous belt 307 passes through the side of the support 2 and meshes with the synchronous pulley 3091 for transmission. The rotation of the drive unit 309 can drive the lead screw 305 to rotate, and when the lead screw 305 rotates, it can move the membrane plate frame 304 up and down.

[0018] The sliding rod 302 is slidably connected to the membrane plate frame 304, and the lead screw 305 is threadedly connected to the membrane plate frame 304. The membrane plate frame 304 has elongated holes 3041 around its perimeter, which are slidably connected to the limiting plate 303. These four elongated holes 3041 facilitate the entry and exit of the limiting plate 303, limiting the cutting of the membrane and ensuring neat placement. Figure 5 and Figure 6As shown, multiple through slots 3043 are provided in the middle, extending to one end of the membrane frame 304. The length direction of the through slots 3043 is parallel to the width direction of the membrane frame 304. A through slot 3044 is provided in the middle of the other end of the membrane frame 304. A magnetic strip 3045 is fixedly connected to one end of the through slot 3043 near the through slot 3044. A through hole 3046 is provided on the membrane frame 304 between two through slots 3043. A movable plate 3042 is slidably connected to the support 043. A magnetic strip 3042A is fixedly connected to the bottom of the movable plate 3042 near the second magnetic strip 3045. Magnetic strip 3042A is slidably connected to the through hole 3046, and magnetic strips 3042A and 3045 attract each other. A telescopic device 306 is fixedly connected to the bottom of one side of the support 2 along its length. A magnet is fixedly connected to the extended end of the telescopic device 306, and the magnet attracts magnetic strip 3042A. The movable plate 3042 can move on the membrane frame 304. The upper end of the movable plate 3042 is flush with the upper end of the membrane frame 304. Therefore, when the movable plate 3042 moves, it can push the membrane placed on the membrane frame 304. Furthermore, the telescopic end of the telescopic device 306 abuts against the membrane for further movement.

[0019] The die-cutting mechanism 1 includes a crankshaft 102 rotatably connected to a support 2. One end of the crankshaft 102 is equipped with a drive device 101 fixedly connected to the support 2. The rotating end of the drive device 101 is fixedly connected to the crankshaft 102. A connecting rod 103 is rotatably connected to the middle of the crankshaft 102. The rotation of the drive device 101 drives the crankshaft 102 to rotate, and the crankshaft 102 drives the connecting rod 103 to move up and down. The bottom of the connecting rod 103 passes through the top of the support 2, and one end of the connecting rod 103 is rotatably connected to a die-cutting table 104. Four limiting corner plates 207 are fixedly connected below the top of the support 2. The limiting corner plates 207 are slidably connected to the corners of the die-cutting table 104, better restricting the up and down movement of the die-cutting table 104.

[0020] like Figures 1 to 2As shown, a drive roller 208 is rotatably connected to one end of the support 2 along its length. A turbine 209 is fixedly connected to one end of the drive roller 208, and a driven roller 218 is rotatably connected to the other end. A turbine 217 is fixedly connected to one end of the driven roller 218. A shaft 216 is rotatably connected to the support 2 on the same side as the turbines 209 and 217. Worms 210 are fixedly connected to both ends of the shaft 216. The worms 210 on both sides are meshed with the turbines 209 and 217 respectively for transmission. The shaft 216 is close to the drive roller 209. A bevel gear 215 is fixedly connected to one side of the bracket. A shaft 213, rotatably connected to the bracket, is located at the bottom of the bevel gear 215. A bevel gear 214 is fixedly connected to the upper part of the shaft 213, meshing with the bevel gear 215 for transmission. A bevel gear 212 is fixedly connected to the bottom of the shaft 213. A drive device 211, fixedly connected to the bracket, is located at the bottom of the bevel gear 212. A bevel gear 211, rotatably connected to the bracket, is fixedly connected to the rotating end of the drive device 211, meshing with the bevel gear 212 for transmission. This invention uses a single drive device 211 to simultaneously drive the drive roller 208 and the driven roller 218 to achieve synchronous rotation. The reason this invention uses a worm gear 209, a worm 210, and a worm gear 217 as the transmission method, instead of a traditional belt or chain, is that when a belt or chain is connected to the drive device 211, its rotation can affect the already cut film, potentially causing it to move.

[0021] A second drive device 201 is fixedly connected to one side of the top of the support 2 in the width direction. A spool 202 is fixedly connected to the rotating end of the drive device 201. A cable 203 is fixedly connected to the spool 202. One end of the cable 203 is fixedly connected to a lifting plate 204. The bottom of the lifting plate 204 has a chamfer to better separate the telescopic end of the telescopic device 306 from the cut film. Limiting grooves 205 are provided on both sides of the lifting plate 2 in the length direction, which are fixedly connected to the support 2. The limiting grooves 205 and the lifting plate 204 are slidably connected to each other, which facilitates the up and down sliding of the lifting plate 204. The bottom of the lifting plate 204 has a support platform 206 fixedly connected to the support 2 to place the stacked film for the next step of packaging.

[0022] Those skilled in the art can use existing technologies they possess, such as installing appropriate mechanical limit switches or photoelectric sensors, to limit the specified positions of each actuator during the following operation process; to achieve automated operation, this utility model can use numerical control technology or PLC to control the actions of each actuator.

[0023] Working process: In this invention, the film roll is placed on the driven roller 218. After power is turned on, the film is moved from the driven roller 218, through the bracket 2, and placed on the drive roller 208. The drive device 3 211 is started. The first bevel gear 2111 rotates, driving the second bevel gear 212 to rotate. The third bevel gear 214 rotates, driving the fifth bevel gear 215 to rotate. When the shaft 216 rotates, the worm gears 210 on both sides drive the first worm gear 209 and the second worm gear 217 to rotate respectively. Finally, the drive roller 208 and the driven roller 218 rotate, allowing the film roll to rotate. When the film passes through the middle of the bracket 2, the drive device 101 rotates, driving the crankshaft 102 to rotate. The connecting rod 103 on the crankshaft 102, under the action of the crankshaft 102, begins to drive the die-cutting table 104 to move up and down. When the die-cutting table 104 moves up and down, it cuts the film off the film roll and places it on the film plate holder 304. The limiting plates 303 around the perimeter restrict the film and prevent it from shifting. As more and more film falls onto the membrane frame 304, the drive device 309 rotates, synchronously driving the two lead screws 305 to rotate via the synchronous belt 307, causing the membrane frame 304 to move downwards. When the height of the film on the membrane frame 304 is consistent with the height of the limit plate 303, the membrane frame 304 slowly moves downwards. When the membrane frame 304 moves to be level with the telescopic end of the telescopic device 306, it stops moving downwards. The telescopic device 306 extends forward, pushing the moving plate 3042 on one side and pushing the cut film on the other. When the film is pushed to the upper part of the support platform 206, the drive device 201 rotates, moving the lifting plate 204 pulled by the cable 203 downwards, separating the film from the telescopic device 306. Then, the moving plate 3042 retracts backwards under the magnetic attraction of the telescopic device 306, and the cut film falls onto the support platform 206 to await packaging by the workers. When the moving plate 3042 retracts backward, magnetic strips 3042A and 3045 attract each other, and the extended end of the telescopic device 306 disconnects from the moving plate 3042. The film holder 304 then rises again, awaiting the next die-cutting operation.

[0024] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
