Description

Technical Field

[0001] This utility model relates to the technical field of zipper bag production equipment, specifically to a zipper bag die-cutting device. Background Technology

[0002] Profile cutting machines, also known as abrasive wheel saws, are suitable for sawing various irregularly shaped metals such as aluminum, aluminum alloys, copper, copper alloys, non-metallic plastics, and carbon fiber. They offer precise cutting angles, low vibration and noise, simple operation, and high efficiency, and can saw single or multiple profiles at the same time.

[0003] In the process of profile cutting, it is often necessary to cut the profile according to the required size according to the construction situation. The existing positioning cutting method is generally to mark the positioning on the profile and then cut the profile by aligning the cutting machine with the marked line. However, this method requires repeated positioning when continuous cutting of the same size is required, and the manual marking and alignment process is also prone to errors due to subjective factors, making the operation process cumbersome. Utility Model Content

[0004] To solve the above problems, this utility model proposes a zipper bag die-cutting device, including a frame, a die-cutting box mounted on the frame, a partition inside the die-cutting box, a die-cutting cylinder on the top surface of the partition, a die-cutting assembly vertically downward connected to the output end of the die-cutting cylinder, a die-cutting assembly cooperating with a lower anvil, a lifting assembly connected to the bottom surface of the anvil, a cross frame at the outlet of the die-cutting box, an ejector cylinder mounted on the cross frame, a roller rotatably connected to the output end of the ejector cylinder, a roller cooperating with a lower axle, an axle motor connected to the end of the axle mounted on the outside of the cross frame, a conveyor inlet connected to the rear of the axle, and a waste material assembly connected to the bottom of the axle.

[0014] The present invention will be further described below with reference to the accompanying drawings: like Figures 1 to 3 As shown, a zipper bag die-cutting device includes a frame 1, a die-cutting box 2 mounted on the frame 1, a partition 3 inside the die-cutting box 2, a die-cutting cylinder 4 on the top surface of the partition 3, the output end of the die-cutting cylinder 4 vertically downward through the partition 3 and connected to the center of the top surface of the die-cutting plate 12 in the die-cutting assembly, positioning rods 1201 at the four corners of the top surface of the die-cutting plate 12, the positioning rods 1201 being vertically slidably connected to the positioning cylinders 301 on the partition 3, and two sets of profile cutting plates 13 arranged horizontally side by side on the bottom surface of the die-cutting plate 12. The die-cutting assembly cooperates with the lower anvil 5. The bottom surface of the anvil 5 is connected to the lifting assembly, which includes a worm gear 14. The outer gear ring of the worm gear 14 meshes with the worm 15. Both the worm gear 14 and the worm 15 are rotatably connected to the worm nest 201 on the inner bottom surface of the die-cutting box 2. The end of the worm 15 passes through the outer wall of the die-cutting box 2 and is connected to the handwheel 1501. The center of the worm gear 14 is threadedly connected to the lifting shaft 16. The top of the lifting shaft 16 is rotatably connected to the center of the bottom surface of the anvil 5. The bottom surface of the anvil 5 is provided with slide rods 501 on both sides. The slide rods 501 are vertically slidably connected to the sleeve 202 on the bottom surface of the die-cutting box 2.

[0015] In this embodiment, a positioning sensor 17 is provided at the feed inlet of the die-cutting box 2, and a cross frame 6 is provided at the discharge outlet of the die-cutting box 2. An ejector cylinder 7 is installed on the cross frame 6. An adjusting screw 701 is provided on the top surface of the ejector cylinder 7. The adjusting screw 701 passes through the transverse groove 601 on the top surface of the cross frame 6 and is fastened by a nut. The output end clamp of the ejector cylinder 7 is rotatably connected to a roller 8. The roller 8 cooperates with the lower axle 9. The axle 9 is a camshaft. The camshaft's shaft protrusion is directly opposite the roller 8. The end of the axle 9 is connected to a wheel axle motor 10 installed on the outside of the cross frame 6. The rear of the axle 9 is connected to the inlet of the conveyor 11. The lower part of the axle 9 is connected to a residual material assembly. The residual material assembly includes an upper connecting roller 18 and a lower connecting roller 19. The two ends of the upper and lower connecting rollers are rotatably connected to the frame 1. The lower connecting roller 19 is connected to the residual material roller 20. The end of the residual material roller 20 is connected to the output end of the winding motor 21. The winding motor 21 is installed on the mounting arm 101 on one side of the bottom of the frame 1.

[0016] The working principle of this utility model is as follows: After heat sealing and molding, the composite raw material strip enters the die-cutting box 2 from the feed port. The positioning sensor 17 identifies the markings on the side of the raw material strip and controls the die-cutting cylinder 4 to drive the die-cutting plate 12 to move up and down reciprocally. Each time the die-cutting plate 12 moves down, the profile cutter 13 presses the raw material strip below onto the anvil 5 and cuts out two zipper bag outlines side by side. Then the raw material strip is pulled forward to reach the bottom of the cross frame 6. At this time, the ejector cylinder 7 drives the roller 8 to move down and eject the zipper bag from the excess material strip. The zipper bag ejected by the roller is conveyed out of the production line by the conveyor 11. The excess material is guided by the upper and lower connecting rollers and then wound into the waste material roller 20 for collection. In the above process, the winding motor 21 and the wheel axle motor 10 rotate the waste material roller 20 and the wheel axle 9 respectively, pulling the raw material strip to move forward.

[0017] This invention uses a die-cutting cylinder 4 to drive a die-cutting assembly to cut the contour of the heat-sealed raw material strip. The anvil 5 in the device can be freely adjusted in height to ensure that the cutting is not completely through. The cut raw material strip is separated by an ejector cylinder 7, and the ejected zipper bag is conveyed out of the production line by a conveyor 11. The remaining material is collected in a scrap material assembly.

[0018] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
