Description

Technical Field

[0001] This utility model relates to the field of plastic packaging box processing technology, specifically to a die-cutting and creasing mechanism for plastic packaging boxes. Background Technology

[0002] Plastic packaging boxes are containers made of plastic materials, commonly used for packaging and protecting goods. They are widely used in various industries such as food, electronics, daily necessities, and cosmetics. They can effectively prevent damage to products from the external environment and facilitate storage and transportation. When processing plastic packaging boxes, the plastic material is cut into specific shapes using a cutting tool. Based on the cut, pressure is applied to form fold lines or indentations on the plastic to facilitate subsequent folding and assembly. These indentations help the packaging box to be formed more easily.

[0003] Patent CN221605270U discloses a creasing and die-cutting device for paper packaging processing, including a base box and vertical rods. Two vertical plates are fixedly connected inside the base box, and a rotating shaft is rotatably connected to each vertical plate. A self-locking stepper motor is fixedly connected to one of the vertical plates and connected to the rotating shaft. A multi-faceted prism is fixedly mounted on the rotating shaft, and different creasing and die-cutting dies are mounted on each mounting surface of the multi-faceted prism. A gantry frame is fixedly connected to the top of the base box, and a clamping cylinder is fixedly mounted on the gantry frame. A pressure plate is fixedly connected to the piston rod end of the clamping cylinder. This invention uses different creasing and die-cutting dies mounted on different mounting surfaces of the multi-faceted prism. When switching to process different paper packaging boxes, it is only necessary to start the stepper motor to rotate the required creasing and die-cutting die to the top, thus avoiding on-site downtime for disassembling and installing new creasing dies, preventing production delays, and improving the production efficiency of paper packaging boxes.

[0004] Based on existing solutions and actual use, there are still some problems with current die-cutting and creasing for plastic packaging boxes. For example, when using a die-cutting and creasing device to process plastic materials, the plastic material may slip or deform due to gravity or friction during the conveying process, making it impossible to keep it in the set position. This results in inaccurate cutting or creasing positions, which in turn leads to machine blockage or uneven cutting, thus affecting subsequent processing steps. Utility Model Content

[0005] The purpose of this utility model is to provide a die-cutting and creasing mechanism for plastic packaging boxes, so as to solve the problem mentioned in the background art that in the current process of processing plastic materials, during the conveying process, the plastic material may slide or deform due to gravity or friction, which not only makes it impossible to keep it in the set position, but also causes the cutting or creasing position to be inaccurate, thus affecting the subsequent processing steps.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a die-cutting and creasing mechanism for plastic packaging boxes, comprising:

[0007] The operating table has a processing chamber for cutting and creasing film installed at the top left end. A feeding plate for feeding material is installed at the left end of the operating table, and the feeding plate has rollers arranged in an array on its body. The feeding plate is also inclined. A hopper is fixedly installed at the left end of the operating table, and the left end of the hopper is inclined. The hopper is positioned in a corresponding manner to the feeding plate. A conveying structure and a positioning structure are provided at the top of the operating table.

[0008] Preferably, the conveying structure includes a through groove, a synchronous pulley, a conveyor belt, and a motor. The front and rear ends of the operating platform are provided with through grooves. The left and right ends of the through groove are rotatably connected to synchronous pulleys. The left synchronous pulley in the through groove and the right synchronous pulley in the through groove are connected together by the conveyor belt. The front and rear ends of the operating platform are fixedly installed with motors, and the output end of the motors is connected to the synchronous pulleys.

[0009] Preferably, the conveyor belt and the operating table are arranged at the same horizontal level, and the conveyor belt and the processing chamber are arranged in a corresponding manner.

[0010] Preferably, the positioning structure includes a mounting bracket, a sliding block, a first spring, and a rotating wheel. The mounting bracket is installed at both the front and rear ends of the right end of the operating table. The sliding block is slidably connected to the plate of the mounting bracket, and the sliding block is arranged in an array about the horizontal line of the mounting bracket. The first spring is arranged in an array on the plate of the mounting bracket, and the lower end of the first spring is fixedly connected to the upper end of the sliding block. The rotating wheel is rotatably connected to the side wall of the sliding block, and the rotating wheel is set in a close-fitting state with the top of the operating table.

[0011] Preferably, mounting plates are fixedly installed at both the front and rear ends of the right end of the processing chamber, and guide wheels are arranged in an array at the bottom of the mounting plate.

[0012] Preferably, a sliding groove is provided at the middle position of the mounting plate, and a hinge block is slidably connected inside the sliding groove. A second spring is installed at the top of the sliding groove, and the lower end of the second spring is connected to the top of the hinge block. A connecting rod is fixedly installed on the block, and a support mounting rod is fixedly installed on the rod. A rotating roller is rotatably connected to the rod, and the rotating roller is located above the conveyor belt.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The die-cutting and creasing mechanism for the plastic packaging box can achieve guidance during the conveying process through the cooperation between the conveyor belt and the guide wheel, which can keep the material moving and positioned continuously during the material processing. At the same time, the rotating wheel and rotating roller can ensure that the material position remains unchanged during the processing, thereby ensuring that the material will not slip during the processing, thus ensuring the accuracy of film cutting and creasing, and improving the stability of the processing process. Then, by collecting the processed material in a centralized manner, it is convenient for subsequent material picking, reprocessing or packaging, reducing the time spent searching for and collecting materials.

[0014] 1. The system is equipped with an operating platform, a through-slot, synchronous pulleys, a conveyor belt, a motor, mounting plates, and guide wheels. The synchronous pulleys inside the through-slot are connected together by the conveyor belt, and the motor output is also connected to the through-slot. This allows the motor to drive the conveyor belt through the synchronous pulleys. Since the conveyor belt is level with the operating platform, mounting plates are fixedly installed at both ends of the right side of the processing chamber. Guide wheels are arranged in an array at the bottom of the mounting plates. The rotation of the conveyor belt transports the plastic material, and the rotation of the guide wheels on the mounting plates guides the plastic material. The cooperation between the conveyor belt and the guide wheels ensures guidance during the transport process, maintaining continuous movement and positioning of the material during processing. This effectively avoids deviations caused by the transport operation and ensures the accuracy of die-cutting and creasing.

[0015] 2. The system is equipped with a mounting frame, a sliding block, a first spring, a rotating wheel, a sliding groove, a hinge block, a second spring, a connecting rod, a mounting rod, and a rotating roller. The sliding block is driven by the elastic force of the first spring to slide on the plate of the mounting frame, and the elastic force of the first spring drives the rotating wheel to be in contact with the top of the operating table through the sliding block. At the same time, the elastic force of the second spring drives the hinge block to slide in the groove of the sliding groove. Since the connecting rod is fixedly installed on the hinge block, and the mounting rod is fixedly installed on the connecting rod, the rotating roller is rotatably connected to the mounting rod. The elastic force of the second spring drives the rotating roller to be in contact with the operating table and the conveyor belt. The cooperation of the rotating wheel and the rotating roller can position the plastic material. The rotating wheel and the rotating roller ensure that the position of the material remains unchanged, reducing the problem of uneven cutting or indentation caused by movement or deviation. It also ensures that the material will not slip during processing, thereby improving the stability of the processing.

[0016] 3. The system is equipped with an operating platform, a feeding plate, and a hopper. The feeding plate is installed at an angle on the left end of the operating platform, and the hopper is fixedly installed on the left end of the operating platform. The left end of the hopper is also set at an angle. The feeding plate is set in a corresponding position to the hopper. Rollers are arranged in an array on the feeding plate, so that the processed plastic material is transported to the hopper. The processed material is then collected in a centralized manner. Collecting the processed material facilitates subsequent material retrieval, reprocessing, or packaging, reducing the time required for finding and sorting materials. Attached Figure Description

[0024] 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.

[0025] Please see Figure 1-6This utility model provides a technical solution: a die-cutting and creasing mechanism for plastic packaging boxes, comprising: an operating table 1, a processing chamber 2, a feeding plate 3, a hopper 4, a through groove 5, a synchronous pulley 6, a conveyor belt 7, a motor 8, a mounting frame 9, a sliding block 10, a first spring 11, a rotating wheel 12, a mounting plate 13, a guide wheel 14, a sliding groove 15, a hinge block 16, a second spring 17, a connecting rod 18, a mounting rod 19, and a rotating roller 20.

[0026] Example 1; please refer to the appendix. Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 and attached Figure 6 As shown, when processing plastic materials, mounting brackets 9 are installed at both the front and rear ends of the right side of the operating table 1. Sliding blocks 10 are arranged in an array on the plate of the mounting brackets 9, and are also arranged in an array with first springs 11 connected to the upper ends of the sliding blocks 10. Rotating wheels 12 are rotatably connected to the blocks 10. Simultaneously, through slots 5 are provided at both the front and rear ends of the operating table 1, and synchronous pulleys 6 are rotatably connected to the left and right ends of the slots 5. The synchronous pulleys 6 are connected together by a conveyor belt 7, which is horizontally aligned with the operating table 1. When cutting and creasing the material, the material is first placed on the surface of the operating table 1 and the conveyor belt 7, and then the sliding blocks on the right side of the mounting brackets 9 are pulled upwards. Block 10, because the rotating wheel 12 is set in a state of contact with the surface of the operating table 1, when the rotating wheel 12 is pulled upward, the material is placed between the operating table 1 and the rotating wheel 12, and the elastic force of the first spring 11 drives the rotating wheel 12 to fit precisely with the material, and at the same time, the material is also put into contact with the operating table 1 and the conveyor belt 7. Then, motors 8 are fixedly installed at both ends of the operating table 1, and the output end of the motor 8 is rotatably connected to the synchronous pulley 6, so that the operation of the motor 8 can drive the conveyor belt 7 to rotate through the synchronous pulley 6. Since the material is placed between the rotating wheel 12, the operating table 1, and the conveyor belt 7, the rotation of the conveyor belt 7 can drive the material to move above the operating table 1, and the material movement is placed between the rotating wheel 12 on the mounting frame 9 and the operating table 1, thereby positioning the material.

[0027] When materials are conveyed by the rotation of the conveyor belt 7, mounting plates 13 are fixedly installed at both the front and rear ends of the right side of the processing chamber 2. Guide wheels 14 are arranged in an array on the bottom of the mounting plates 13. When the conveyor belt 7 transports materials, the materials first come into contact with the guide wheels 14 on the mounting plates 13. Since the conveyor belt 7 is arranged in a corresponding manner to the processing chamber 2, the guide wheels 14 ensure that the conveyor belt 7 maintains a precise conveying position during material transport. Sliding grooves 15 are provided on the mounting plates 13, and simultaneously... A hinge block 16 is slidably connected inside the sliding groove 15, and a second spring 17 is installed at the top of the sliding groove 15. The lower end of the second spring 17 is connected to the top of the hinge block 16, so that the spring force of the second spring 17 drives the hinge block 16 to the bottom of the sliding groove 15. A connecting rod 18 is fixedly installed on the hinge block 16, and an mounting rod 19 is fixedly installed on the connecting rod 18. A rotating roller 20 is rotatably connected to the mounting rod 19, so that the spring force of the second spring 17 drives the rotating roller 20 to interact with the operating table 1. When the material is transported along the conveyor belt 7 and guided by the guide wheel 14, it moves to the bottom of the rotating roller 20. When the material is at the bottom of the rotating roller 20, the hinge block 16 slides within the sliding groove 15, compressing the second spring 17. The spring force of the second spring 17 then causes the rotating roller 20 to press against the material, pressing it downwards. This results in the material being pressed against the operating table 1 and the conveyor belt 7, and simultaneously placing the material on the rotating roller 20. Between the roller 20, the operating table 1, and the conveyor belt 7, the conveyor belt 7 is set in a corresponding manner with the processing chamber 2. The material is transported to the interior of the processing chamber 2 by the conveyor belt 7, and the material entering the processing chamber 2 is cut and indented. When processing the material, the material can be guided by the cooperation between the conveyor belt 7 and the guide wheel 14, and deviations can be avoided during the conveying process. At the same time, the cooperation between the conveyor belt 7 and the rotating roller 20 ensures that the material will not slip during the processing, thereby improving the stability of the processing process.

[0028] Example 2; please refer to the appendix. Figure 1 and attached Figure 2As shown, after the material is processed in the processing chamber 2, the feeding plate 3 is installed at the left end of the operating table 1 in an inclined state. Rollers are arranged in an array on the feeding plate 3. The hopper 4 is fixedly installed at the left end of the operating table 1 and is set in a corresponding state with the feeding plate 3. The left end of the hopper 4 is also set in an inclined state, so the processed material enters the hopper 4 through the feeding plate 3. Then, the left end of the hopper 4 is set in an inclined state, so the processed material is arranged on the right end of the hopper 4 through the inclined side wall. The cooperation between the feeding plate 3 and the hopper 4 can collect the processed material in a concentrated manner, which facilitates subsequent material picking, reprocessing or packaging.
