Description

Technical Field

[0001] This utility model relates to the field of packaging bag production technology, specifically a packaging bag production cutting device. Background Technology

[0002] A packaging bag production cutting device is a piece of equipment used in the packaging bag production process to cut raw materials (such as plastic film, paper, or composite materials) to specific specifications or dimensions. This device plays a crucial role in the packaging bag production line, ensuring that the size and shape of the packaging bags meet requirements through precise cutting, thereby improving production efficiency and product quality.

[0003] Currently, commonly used packaging bag production cutting devices mainly consist of a worktable, cutting blades, cutting grooves on the worktable corresponding to the cutting blades, and a control panel. During the cutting process, the cutting blades press the packaging bag's cut edge against the bottom of the cutting groove on the worktable. As the packaging bag is pressed down, it is prone to positional shift during its downward movement, resulting in a positional shift at the cut edge.

[0004] Therefore, we propose a packaging bag production cutting device. Utility Model Content

[0005] To solve the above-mentioned technical problems, this application provides a packaging bag production cutting device, including a workbench and a support frame disposed on the workbench. The support frame is provided with an mounting plate and a cutter disposed on the lower end face of the mounting plate. The upper end face of the support frame is provided with a driving component, and the lower end face of the mounting plate is provided with an auxiliary cutting component. The auxiliary cutting component is used to press and flatten the packaging bag to be cut.

[0006] Preferably, the auxiliary cutting assembly includes a mounting opening on one side of the lower end face of the mounting plate and a mounting box on the other side of the lower end face of the mounting plate. A fixing horizontal plate is inserted into the lower end face of the mounting box, and a helical spring is provided at the bottom inner side of the mounting box. One end of the helical spring is connected to the fixing horizontal plate inserted into the mounting box, and a pressing plate is provided on the lower end face of the fixing horizontal plate.

[0007] Preferably, a pressing wheel is provided below the mounting port, and connecting plates are rotatably connected to both ends of the pressing wheel. One end of each of the two connecting plates is rotatably connected to both ends of the mounting plate.

[0008] Preferably, a first fixing rod is provided between the two connecting plates, and a second fixing rod is provided inside the mounting opening. A connecting ring is sleeved on both the first fixing rod and the second fixing rod, and a compression spring is connected between the connecting rings on the first fixing rod and the second fixing rod.

[0009] Preferably, both the first fixing rod and the second fixing rod are provided with multiple limiting grooves, and the multiple limiting grooves on the first fixing rod and the second fixing rod are in pairs corresponding to each other. Both the first fixing rod and the second fixing rod are provided with multiple connecting rings, and the multiple connecting rings on the first fixing rod and the second fixing rod are respectively fitted into the limiting grooves on the first fixing rod and the second fixing rod.

[0010] Preferably, the first fixing rod is located below the second fixing rod, and the limiting groove is adapted to the size of the connecting ring.

[0011] Preferably, the driving component includes a cylinder disposed on the upper end face of the support frame and guide rods disposed on both sides of the cylinder, wherein the output end of the cylinder and one end of the guide rod both pass through the support frame and are connected to the mounting plate.

[0012] This utility model has at least the following beneficial effects:

[0013] By setting up auxiliary cutting components, one end of the packaging bag can be limited and the surface of the other end of the packaging bag can be rolled and stretched. This not only reduces creases on the surface of the packaging bag caused by irregular placement, but also keeps the packaging bag in a taut state at the cutting point. This allows the packaging bag to be cut directly above the cutting groove, thus avoiding the problem of the packaging bag shifting position when the cutter cuts into the cutting groove, which would reduce the cutting quality of the packaging bag.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 and Figure 2 This utility model provides a technical solution:

[0022] A packaging bag production cutting device includes a workbench 1 and a support frame 2 disposed on the workbench 1. The support frame 2 has an mounting plate 3 disposed on its inner side and a cutter 4 disposed on the lower end face of the mounting plate 3. The upper end face of the support frame 2 is provided with a driving component, and the lower end face of the mounting plate 3 is provided with an auxiliary cutting component 5. The auxiliary cutting component 5 is used to press and flatten the packaging bag to be cut.

[0023] The upper surface of the workbench 1 is provided with a cutting groove, and the cutting groove corresponds to the position of the cutter 4.

[0024] Please see Figure 3 and Figure 5 The auxiliary cutting component 5 includes a mounting opening 51 on one side of the lower end face of the mounting plate 3 and a mounting box 52 installed on the other side of the lower end face of the mounting plate 3. A fixing horizontal plate 54 is inserted into the lower end face of the mounting box 52. A helical spring 55 is provided at the bottom inner side of the mounting box 52. One end of the helical spring 55 is connected to the fixing horizontal plate 54 inserted into the mounting box 52. A pressing plate 56 is provided on the lower end face of the fixing horizontal plate 54.

[0025] The pressing plate 56 can press down one end of the packaging bag located below the cutter 4 to prevent the packaging bag from shifting position during the cutting process. The coil spring 55 is configured to provide elastic downward pressure for the pressing plate 56.

[0026] A pressing wheel 57 is provided below the mounting port 51. The two ends of the pressing wheel 57 are rotatably connected to connecting plates 58. One end of each of the two connecting plates 58 is rotatably connected to the two ends of the mounting plate 3.

[0027] The pressing roller 57 rolls and pulls the surface of the packaging bag away from the pressing end of the packaging bag, which can flatten the wrinkles on the surface of the packaging bag and keep the area to be cut of the packaging bag in a taut state, so that the cutter 4 can cut the area of ​​the packaging bag more smoothly.

[0028] A first fixing rod 59 is provided between the two connecting plates 58, and a second fixing rod 510 is provided inside the mounting port 51. A connecting ring 511 is sleeved on both the first fixing rod 59 and the second fixing rod 510, and a compression spring 512 is connected between the connecting ring 511 on the first fixing rod 59 and the second fixing rod 510.

[0029] The compression spring 512 and the connecting ring 511 are configured to press the packaging bag down with pressure from the pressing roller 57.

[0030] The specific implementation method is as follows: When the driving component drives the cutter 4 to move down and cut the packaging bag, the pressing plate 56 presses on one end of the packaging bag. As the cutter 4 moves down, the pressing plate 56 retracts into the mounting box 52 through the fixed horizontal plate 54, and the pressing roller 57 presses on the packaging bag. During the process of the fixed horizontal plate 54 being retracted into the mounting box 52, the fixed horizontal plate 54 will squeeze the spiral spring 55 inside the mounting box 52. As the cutter 4 continues to move down, the pressing roller 57 rolls on the surface of the packaging bag, and the pressing roller 57 rotates in an arc during the rolling process. During the rotation of the pressing roller 57, the spring 512 between the first fixed rod 59 on the connecting plate 58 at both ends of the pressing roller 57 and the second fixed rod 510 on the mounting plate 3 is compressed. At this time, the cutting part of the packaging bag located below the cutter 4 is in a taut state. As the cutter 4 moves down, the cutter 4 cuts the packaging bag, and the cutter 4 will directly abut against the cutting groove located on the worktable 1.

[0031] By setting the auxiliary cutting component 5, the position of one end of the packaged bag can be limited and the surface of the other end of the packaged bag can be rolled and stretched. This not only reduces the creases on the surface of the packaged bag caused by irregular placement, but also keeps the cut area of ​​the packaged bag in a tight state. This allows the packaged bag to be cut directly above the cutting groove, thus avoiding the problem of the packaged bag shifting position when the cutter 4 cuts the packaged bag into the cutting groove, which would reduce the cutting quality of the packaged bag.

[0032] Both the first fixing rod 59 and the second fixing rod 510 are provided with multiple limiting grooves 513. The multiple limiting grooves 513 on the first fixing rod 59 and the second fixing rod 510 are in pairs corresponding to each other. Multiple connecting rings 511 are provided on the first fixing rod 59 and the second fixing rod 510. The multiple connecting rings 511 on the first fixing rod 59 and the second fixing rod 510 are respectively fitted into the limiting grooves 513 on the first fixing rod 59 and the second fixing rod 510.

[0033] The limiting groove 513 is designed to limit the position of the connecting ring 511.

[0034] The first fixing rod 59 is located below the second fixing rod 510, and the limiting groove 513 is adapted to the size of the connecting ring 511.

[0035] The driving component includes a cylinder 6 disposed on the upper surface of the support frame 2 and guide rods 7 disposed on both sides of the cylinder 6. The output end of the cylinder 6 and one end of the guide rod 7 both pass through the support frame 2 and are connected to the mounting plate 3.

[0036] The cylinder 6 is configured to provide kinetic energy for the up-and-down movement of the cutter 4, and the guide rod 7 is configured to provide guidance for the up-and-down movement of the mounting plate 3.
