A packaging bag die cutting machine with assisted positioning

Abstract

This utility model belongs to the field of die-cutting machine technology, and particularly relates to a packaging bag die-cutting machine with auxiliary positioning. It includes a worktable, with a bidirectional screw installed on the inner wall of the worktable. Both ends of the bidirectional screw are threadedly connected to threaded sliders. A connecting base plate is fixedly connected to the top of each threaded slider. A limiting post is fixedly connected to the top of each connecting base plate. A limiting groove is formed at the connection between the worktable and the limiting post. By setting a baffle and a pressure plate, the rotation of the bidirectional screw drives the two sets of connecting base plates to slide relative to each other through the threaded sliders. The connecting base plate drives the baffle at the top of the limiting post to slide along the groove of the limiting post, so that the baffle is in contact with the packaging bag film roll. Simultaneously, a spring, through its own elasticity, drives the pressure plate at the bottom of the limiting rod to slide vertically, so that the pressure plate is in contact with the packaging bag film roll, preventing the packaging bag film roll from rolling up on both sides during die-cutting and preventing the packaging bag film roll from folding during die-cutting.

Description

Technical Field

[0001] This utility model belongs to the field of die-cutting machine technology, and in particular relates to a packaging bag die-cutting machine with auxiliary positioning. Background Technology

[0002] Die-cutting machines are mainly used for die-cutting, creasing, hot stamping, laminating, and automatic waste removal of various non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronic and mobile phone pads, etc. They utilize steel blades, metal molds, and steel wire, applying pressure through an impression plate to cut printed materials or cardboard into specific shapes. They are essential equipment for post-printing packaging processing.

[0003] For example, patent CN207901742U discloses a packaging bag die-cutting machine, including a base, a lower plate, an upper plate, a mold, and a telescopic device. The telescopic device consists of two components, each fixed to one side of the base. Each telescopic device includes a fixed seat, cylinders mounted at both ends of the fixed seat, a cylinder shaft connected to each cylinder, and two guide shafts mounted in the middle of the fixed seat, each guide shaft fitted with a compression spring. The fixed seats on both sides of the base are connected as a single unit by a support plate. A lower plate is fixedly mounted on the support plate. An upper plate is fitted through the cylinder shaft, with its lower end abutting against the compression spring. A mold is fixed to the bottom surface of the upper plate, and cutting blades are arranged along the mold. The distance between the cutting blades and the lower plate is adjusted by the compression spring to leave a certain gap for the packaging film to pass through. The cylinders are driven by a motor. This utility model provides a packaging bag die-cutting machine with a simple structure and high degree of automation. It can flexibly cut packaging bags into different shapes depending on the mold.

[0004] Existing packaging bag die-cutting machines often experience film roll-up on both sides during operation, leading to folding of the film roll during die-cutting. To address this, we propose a packaging bag die-cutting machine with assisted positioning. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a packaging bag die-cutting machine with auxiliary positioning capabilities, thereby preventing the packaging bag film roll from rolling up on both sides.

[0006] In view of this, the present invention provides a packaging bag die-cutting machine with auxiliary positioning, including a worktable, a bidirectional screw is provided on the inner wall of the worktable, both ends of the bidirectional screw are threadedly connected to threaded sliders, a connecting base plate is fixedly connected to the top of the threaded sliders, a limit post is fixedly connected to the top of the connecting base plate, a limit groove is formed at the connection between the worktable and the limit post, a baffle is fixedly connected to the top of the limit post, a fixing plate is fixedly connected to the side wall of the baffle, a limit rod passes through the inner wall of the fixing plate, a pressure plate is fixedly connected to the bottom end of the limit rod, and a spring is fixedly connected to the connection between the pressure plate and the fixing plate;

[0007] A die-cutting assembly, located at the top of the worktable, is used for die-cutting the film roll.

[0008] Based on the above structure, the rotation of the bidirectional screw drives the two sets of connecting base plates to slide relative to each other through the threaded slider. The connecting base plates drive the baffle at the top of the limiting post to slide along the groove of the limiting groove, so that the baffle is in contact with the packaging bag film roll. At the same time, the spring drives the pressure plate at the bottom of the limiting rod to slide vertically through its own elastic force, so that the pressure plate is in contact with the packaging bag film roll, thus preventing the packaging bag film roll from rolling up on both sides during die cutting and preventing the packaging bag film roll from folding during die cutting.

[0009] Preferably, the connecting base plate is parallel to the baffle, and the baffle forms a sliding structure between the limiting post and the limiting groove. In this embodiment, the connecting base plate drives the baffle at the top of the limiting post to slide along the groove of the limiting groove, so that the baffle is in contact with the packaging bag film roll.

[0010] Preferably, the cross-section of the baffle is "L" shaped. In this embodiment, by setting the baffle with an "L" shaped cross-section, the stability of the baffle is improved.

[0011] Preferably, the baffle and the fixing plate are perpendicular, and the fixing plate is parallel to the pressure plate. In this embodiment, the spring drives the pressure plate at the bottom of the limiting rod to slide vertically through its own elastic force, so that the pressure plate is in contact with the packaging bag film roll, thus preventing the packaging bag film roll from rolling up on both sides during die cutting.

[0012] Preferably, the die-cutting assembly includes:

[0013] A crossbeam is fixedly connected to the top of the workbench and slidably connected to the top of the baffle. A pneumatic push rod is fixedly connected to the top of the crossbeam, and a lifting block is fixedly connected to the output end of the pneumatic push rod. A support plate that is movably connected to the bottom end of the crossbeam is screwed to one end of the lifting block. A base is movably connected to the bottom end of the support plate, and a pressure roller is screwed to the bottom end of the base. A die-cutting frame is fixedly connected to one side of the crossbeam at the top of the workbench. A working cylinder is fixedly connected to the top of the die-cutting frame, and a lifting platform is fixedly connected to the output end of the working cylinder. A die-cutting plate is fixedly connected to the bottom end of the lifting platform. In this embodiment, the pneumatic push rod drives the lifting block to slide vertically, and the lifting block drives the two sets of support plates to rotate relative to each other. Then, the support plate moves and drives the pressure roller at the bottom end of the base to fit against the outer wall of the packaging bag film roll, avoiding the middle position of the packaging bag film roll from being concave, which would cause the die-cutting position of the packaging bag film roll to shift. Then, the working cylinder drives the die-cutting plate at the bottom end of the lifting platform to perform the die-cutting operation on the packaging bag film roll.

[0014] Preferably, there are two sets of crossbeams, which are symmetrical about the die-cutting frame. In this embodiment, this facilitates the positioning of the packaging bag film rolls on both sides of the die-cutting plate.

[0015] Preferably, the support plate is provided in two sets, and the two sets of support plates are distributed in an "X" shape about the lifting block. In this embodiment, the lifting block drives the two sets of support plates to rotate relative to each other, and then the movement of the support plates causes the pressure roller at the bottom of the base to fit against the outer wall of the packaging bag film roll, so as to avoid the middle position of the packaging bag film roll being dented.

[0016] The beneficial effects of this utility model are:

[0017] 1. This packaging bag die-cutting machine with auxiliary positioning, by setting baffles and pressure plates, the rotation of the bidirectional screw drives the two sets of connecting base plates to slide relative to each other through the threaded slider. The connecting base plates drive the baffle at the top of the limiting post to slide along the groove of the limiting groove, so that the baffle is in contact with the packaging bag film roll. At the same time, the spring drives the pressure plate at the bottom of the limiting rod to slide vertically through its own elastic force, so that the pressure plate is in contact with the packaging bag film roll, thus preventing the packaging bag film roll from rolling up on both sides during die-cutting and preventing the packaging bag film roll from folding during die-cutting.

[0018] 2. This packaging bag die-cutting machine with auxiliary positioning uses pressure rollers and pneumatic push rods to drive the lifting block to slide vertically. The lifting block drives two sets of support plates to rotate relative to each other. In turn, the movement of the support plates causes the pressure roller at the bottom of the base to fit against the outer wall of the packaging bag film roll, thus preventing the middle position of the packaging bag film roll from being recessed, which would cause the die-cutting position of the packaging bag film roll to shift.

[0027] This application discloses a packaging bag die-cutting machine with assisted positioning, including a worktable 1. A bidirectional screw 2 is provided on the inner wall of the worktable 1. Both ends of the bidirectional screw 2 are threadedly connected to threaded sliders 3. A connecting base plate 4 is fixedly connected to the top of the threaded slider 3.

A limit rod 9 passes through the inner wall of the fixing plate 8. A pressure plate 10 is fixedly connected to the bottom end of the limit rod 9. A spring 11 is fixedly connected to the connection between the pressure plate 10 and the fixing plate 8.

[0028] The die-cutting assembly is located at the top of the worktable 1 and is used for the die-cutting operation of the film roll.

[0029] Based on the above structure, the rotation of the bidirectional screw 2 drives the two sets of connecting base plates 4 to slide relative to each other through the threaded slider 3. The connecting base plate 4 drives the baffle 7 at the top of the limiting post 5 to slide along the groove of the limiting groove 6, so that the baffle 7 is in contact with the packaging bag film roll. At the same time, the spring 11 drives the pressure plate 10 at the bottom of the limiting rod 9 to slide vertically through its own elastic force, so that the pressure plate 10 is in contact with the packaging bag film roll, thus preventing the packaging bag film roll from rolling up on both sides during die cutting and preventing the packaging bag film roll from folding during die cutting.

[0030] In one embodiment, the connecting base plate 4 is parallel to the baffle 7, and the baffle 7 forms a sliding structure between the limiting post 5 and the limiting groove 6.

[0031] In this embodiment, the connecting base plate 4 drives the baffle 7 at the top of the limiting post 5 to slide along the groove of the limiting groove 6, so that the baffle 7 fits into the packaging bag film roll.

[0032] In one embodiment, the cross-section of the baffle 7 is "L" shaped.

[0033] In this embodiment, by setting a baffle 7 with an "L" shaped cross-section, the stability of the baffle 7 can be improved.

[0034] In one embodiment, the baffle 7 and the fixing plate 8 are perpendicular to each other, and the fixing plate 8 is parallel to the pressure plate 10.

[0035] In this embodiment, the spring 11 drives the pressure plate 10 at the bottom of the limiting rod 9 to slide vertically through its own elastic force, so that the pressure plate 10 fits with the packaging bag film roll, thus preventing the packaging bag film roll from rolling up on both sides during die cutting.

[0036] In one embodiment, the die-cutting assembly includes:

[0037] A crossbeam 12 is fixedly connected to the top of the workbench 1 and slidably connected to the top of the baffle 7. A pneumatic push rod 13 is fixedly connected to the top of the crossbeam 12. A lifting block 14 is fixedly connected to the output end of the pneumatic push rod 13. A support plate 15 is screwed to one end of the lifting block 14 and movably connected to the bottom end of the crossbeam 12. A base 16 is movably connected to the bottom end of the support plate 15. A pressure roller 17 is screwed to the bottom end of the base 16. A die-cutting frame 18 is fixedly connected to one side of the crossbeam 12 at the top of the workbench 1. A working cylinder 19 is fixedly connected to the top of the die-cutting frame 18. A lifting platform 20 is fixedly connected to the output end of the working cylinder 19. A die-cutting plate 21 is fixedly connected to the bottom end of the lifting platform 20.

[0038] In this embodiment, the pneumatic push rod 13 drives the lifting block 14 to slide vertically. The lifting block 14 drives the two sets of support plates 15 to rotate relative to each other. Then, the support plate 15 moves and drives the pressure roller 17 at the bottom of the base 16 to fit against the outer wall of the packaging bag film roll, so as to avoid the middle position of the packaging bag film roll being concave, which would cause the die-cutting position of the packaging bag film roll to shift. Then, the working cylinder 19 drives the die-cutting plate 21 at the bottom of the lifting platform 20 to perform die-cutting operation on the packaging bag film roll.

[0039] In one embodiment, two sets of crossbeams 12 are provided, and the two sets of crossbeams 12 are symmetrical about the die-cutting frame 18.

[0040] In this embodiment, it is convenient to position the packaging bag film rolls on both sides of the die-cutting plate 21.

[0041] In one embodiment, two sets of support plates 15 are provided, and the two sets of support plates 15 are distributed in an "X" shape about the lifting block 14.

[0042] In this embodiment, the lifting block 14 drives the two sets of support plates 15 to rotate relative to each other, and then the movement of the support plates 15 causes the pressure roller 17 at the bottom of the base 16 to fit against the outer wall of the packaging bag film roll, so as to avoid the middle position of the packaging bag film roll being dented.

[0043] In this embodiment of the packaging bag die-cutting machine with assisted positioning, the packaging bag film roll is first passed through the worktable 1. The operator rotates the bidirectional screw 2. The rotation of the bidirectional screw 2 drives the two sets of connecting base plates 4 to slide relative to each other through the threaded slider 3. The connecting base plate 4 drives the baffle 7 at the top of the limiting post 5 to slide along the groove of the limiting groove 6, so that the baffle 7 is in contact with the packaging bag film roll. At the same time, the spring 11 drives the pressure plate 10 at the bottom of the limiting rod 9 to slide vertically through its own elasticity, so that the pressure plate 10 is in contact with the packaging bag film roll, thus preventing the packaging bag film roll from rolling up on both sides during die-cutting and preventing the packaging bag film roll from folding during die-cutting.

[0044] Next, the pneumatic push rod 13 drives the lifting block 14 to slide vertically. The lifting block 14 drives the two sets of support plates 15 to rotate relative to each other. Then, the support plate 15 moves and drives the pressure roller 17 at the bottom of the base 16 to fit against the outer wall of the packaging bag film roll, so as to avoid the middle position of the packaging bag film roll being recessed, which would cause the die-cutting position of the packaging bag film roll to shift.

[0045] Finally, the working cylinder 19 drives the die-cutting plate 21 at the bottom of the lifting platform 20 to perform die-cutting operation on the packaging bag film roll.
