Technical Field

[0001] This utility model relates to the field of plastic packaging film processing technology, specifically a die-cutting device for processing plastic packaging film. Background Technology

[0002] Die-cutting is one of the most commonly used processes in packaging and printing. It involves using die-cutting blades to assemble a die-cutting plate according to the product design requirements, and then cutting the printed material or other coiled blanks into the required shape or cuts under pressure. Plastic bags are bags made primarily of plastic and are essential items in people's daily lives. They are often used to hold other items and are widely used due to their advantages of being inexpensive, extremely lightweight, having a large capacity, and being easy to store. In the production process of plastic bags, an indispensable piece of equipment is the die-cutting device, which can cut plastic bag raw materials into various irregularly shaped individual bags.

[0003] During the die-cutting process, the paper packaging may stick to the mold, causing blockage of the mold cavity and thus damaging the die-cutting blade.

[0004] The present invention aims to solve the technical problems existing in the prior art. To this end, a die-cutting device for processing plastic packaging film is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a die-cutting device for processing plastic packaging film, so as to solve the problems mentioned in the background art.

[0008] The lower mold body is equipped with a transmission mechanism, which cooperates with the die-cutting assembly. The lower mold body is slidably connected to an extrusion device, which cooperates with the transmission mechanism.

[0009] As a further embodiment of this utility model: the lower mold body includes a lower mold, the lower mold is fixedly connected to the bracket, a mold cavity is opened on one side of the lower mold, a lifting block is slidably connected to the lower mold, the lifting block cooperates with the extrusion device, a top block is fixedly connected to one side of the lifting block, the top block extends into the mold cavity and slides in contact with the bracket, and a buffer pad is provided on one side of the lower mold.

[0010] As a further embodiment of this utility model: the extrusion device includes a movable plate, which is located in the lower mold and slidably connected to the lower mold. The movable plate cooperates with the transmission mechanism. A triangular block is fixedly connected to one end of the movable plate. The hypotenuse of the triangular block slides in contact with the lifting block. A spring is fixedly connected to one side of the movable plate. The other end of the spring is fixedly connected to the lower mold.

[0011] As a further embodiment of this utility model: the transmission mechanism includes a rotating cylinder, which is rotatably connected to the lower mold. An extrusion block is fixedly connected to the cylindrical surface of the rotating cylinder. The extrusion block cooperates with the moving plate. A sliding groove is provided on the inner surface of the rotating cylinder. The sliding groove is inclined and cooperates with the die-cutting assembly.

[0012] As a further embodiment of this utility model: the die-cutting assembly includes a hydraulic cylinder, which is fixedly connected to a bracket. A telescopic rod is provided on one side of the hydraulic cylinder, and an upper mold is fixedly connected to the other end of the telescopic rod. A cutter is fixedly connected to one side of the upper mold, and a positioning rod is fixedly connected to the upper mold. The positioning rod extends into the rotating cylinder and slides in contact with the lower mold. A slider is fixedly connected to the cylindrical surface of the positioning rod, and the slider is located in the groove and slides in contact with the rotating cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When the device is in use, the hydraulic cylinder controls the telescopic rod to descend, the telescopic rod drives the upper mold to descend, the upper mold drives the cutter to descend so that the cutter enters the mold cavity to die-cut the plastic packaging film. After the die-cutting is completed, the upper mold drives the cutter to rise, and at the same time the upper mold drives the positioning rod to rise, the positioning rod drives the slider to rise. Since the slider is located in the slide groove and slides in contact with the rotating cylinder, the slide groove is inclined. That is, when the slider rises, it drives the rotating cylinder to rotate, the rotating cylinder drives the extrusion block to rotate, and the extrusion block extrudes the moving plate, that is, the moving plate moves to the right. The moving plate drives the triangular block to move to the right. When the triangular block moves to the right, the inclined side of the triangular block extrudes the lifting block to make it rise. The lifting block then drives the top block to move upward, that is, the top block pushes out the plastic packaging film remaining in the mold cavity, avoiding the plastic packaging film from clogging the mold cavity. This device can prevent the plastic packaging film from clogging the mold cavity, thereby avoiding damage to the cutter. Attached Figure Description

[0021] The lower mold body is equipped with a transmission mechanism, which cooperates with the die-cutting assembly. The lower mold body is slidably connected to an extrusion device, which cooperates with the transmission mechanism. This device can prevent the plastic packaging film from clogging the mold cavity 9, thereby avoiding damage to the cutter 6.

[0022] Please see Figure 1-2 The lower mold body includes a lower mold 2, which is fixedly connected to the support 1. A mold cavity 9 is opened on one side of the lower mold 2. A lifting block 11 is slidably connected to the lower mold 2. The lifting block 11 cooperates with the extrusion device. A top block 10 is fixedly connected to one side of the lifting block 11. The top block 10 extends into the mold cavity 9 and slides in contact with the support 1. A buffer pad 8 is provided on one side of the lower mold 2.

[0023] Please see Figure 2The extrusion device includes a movable plate 13, which is located in the lower mold 2 and slidably connected to the lower mold 2. The movable plate 13 cooperates with the transmission mechanism. A triangular block 12 is fixedly connected to one end of the movable plate 13. The hypotenuse of the triangular block 12 slides in contact with the lifting block 11. A spring 14 is fixedly connected to one side of the movable plate 13. The other end of the spring 14 is fixedly connected to the lower mold 2. When the movable plate 13 moves to the right, the movable plate 13 drives the triangular block 12 to move to the right. When the triangular block 12 moves to the right, the hypotenuse of the triangular block 12 squeezes the lifting block 11 to make it rise. The lifting block 11 then drives the top block 10 to move upward, that is, the top block 10 pushes out the plastic packaging film remaining in the mold cavity 9, so as to avoid the plastic packaging film blocking the mold cavity 9.

[0024] Please see Figure 2-3 The transmission mechanism includes a rotating cylinder 16, which is rotatably connected to the lower mold 2. An extrusion block 17 is fixedly connected to the cylindrical surface of the rotating cylinder 16. The extrusion block 17 cooperates with the moving plate 13. A sliding groove 18 is provided on the inner surface of the rotating cylinder 16. The sliding groove 18 is inclined and cooperates with the die-cutting assembly. Since the slider 15 is located in the sliding groove 18 and slides in contact with the rotating cylinder 16, and the sliding groove 18 is inclined, when the slider 15 rises, it drives the rotating cylinder 16 to rotate. The rotating cylinder 16 drives the extrusion block 17 to rotate, so that the extrusion block 17 extrudes the moving plate 13.

[0025] Please see Figure 1-2 The die-cutting assembly includes a hydraulic cylinder 5, which is fixedly connected to a bracket 1. A telescopic rod 4 is provided on one side of the hydraulic cylinder 5, and an upper mold 3 is fixedly connected to the other end of the telescopic rod 4. A cutter 6 is fixedly connected to one side of the upper mold 3, and a positioning rod 7 is fixedly connected to the upper mold 3. The positioning rod 7 extends into the rotating cylinder 16 and slides in contact with the lower mold 2. A slider 15 is fixedly connected to the cylindrical surface of the positioning rod 7. The slider 15 is located in the slide groove 18 and slides in contact with the rotating cylinder 16. The hydraulic cylinder 5 controls the telescopic rod 4 to descend, which in turn drives the upper mold 3 to descend. The upper mold 3 drives the cutter 6 to descend, allowing the cutter 6 to enter the mold cavity 9 to die-cut the plastic packaging film. After die-cutting is completed, the upper mold 3 drives the cutter 6 to rise, and at the same time, the upper mold 3 drives the positioning rod 7 to rise, which in turn drives the slider 15 to rise.

[0026] The working principle of this utility model is as follows: When the device is in use, the hydraulic cylinder 5 controls the telescopic rod 4 to descend, the telescopic rod 4 drives the upper mold 3 to descend, the upper mold 3 drives the cutter 6 to descend, so that the cutter 6 enters the mold cavity 9 to die-cut the plastic packaging film. After the die-cutting is completed, the upper mold 3 drives the cutter 6 to rise, and at the same time, the upper mold 3 drives the positioning rod 7 to rise, the positioning rod 7 drives the slider 15 to rise. Since the slider 15 is located in the slide groove 18 and slides in contact with the rotating cylinder 16, and the slide groove 18 is inclined, the slider 15 rises. The rotating drum 16 rotates, which in turn causes the extrusion block 17 to rotate, thus extruding the moving plate 13. This causes the moving plate 13 to move to the right, which in turn causes the triangular block 12 to move to the right. When the triangular block 12 moves to the right, its inclined side extrudes the lifting block 11, causing it to rise. The lifting block 11 then causes the top block 10 to move upward, thus pushing out the plastic packaging film remaining in the mold cavity 9. This prevents the plastic packaging film from clogging the mold cavity 9, thereby preventing damage to the cutter 6.
