Abstract
Description
Technical Field
[0001] This invention relates to the field of carton die-cutting technology, and more specifically, to a die-cutting structure that can be used in two ways. Background Technology
[0002] In the field of cardboard box processing and manufacturing, the die-cutting process is the core link that determines the forming accuracy and appearance quality of cardboard boxes. With the rapid development of e-commerce logistics, food packaging and other industries, the market demand for cardboard boxes is gradually showing a diversified and customized trend. In addition to regular rectangular cardboard boxes, the order proportion of irregularly shaped cardboard boxes with special structures continues to increase. Different types of cardboard boxes have put forward differentiated requirements on the cutting accuracy and adaptability of die-cutting equipment, which brings new challenges to the structural design of die-cutting equipment.
[0003] Currently, most die-cutting equipment on the market adopts a single die-cutting working mode, which makes it difficult to meet the processing needs of both regular cartons and irregularly shaped cardboard. For the processing of regular-shaped cartons, the industry mostly uses a steel blade ring die-cutting structure. This structure completes the cutting by adjusting the position of the steel blade ring and using the blade ring and the die-cutting pad to rotate at the same speed to clamp the cardboard. However, the blade ring structure of such equipment is fixed, and its adaptability to irregularly shaped cartons is poor, which cannot meet the processing standards of high-requirement irregularly shaped cartons. Summary of the Invention
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a dual-purpose die-cutting structure, which aims to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a dual-purpose die-cutting structure, comprising a first support, a second support, and two side frames, one side of each of the two side frames being fixedly connected to the first support and the second support respectively, and the second support being located on top of the first support; sliding frames are fixedly connected to both the front and rear sides of each of the two side frames; a wood die-cutting knife assembly for processing cardboard is provided between the two side frames; the wood die-cutting knife assembly includes a wood die-cutting knife body, two connecting columns, two rotating shafts, a second stepper motor, and multiple fixing bolts;
[0006] The outer side of the wood mold knife body is provided with two steel blade ring assemblies for processing cardboard. Each of the two steel blade ring assemblies includes a steel blade ring body, a hollow column, a mounting frame, a gear ring, a gear rod, a first stepper motor, a hydraulic cylinder, and two sliders.
[0007] Furthermore, the two sides of the main body of the wood mold knife are fixed to the two connecting columns by multiple fixing bolts, the two rotating shafts are fixedly connected to the two connecting columns at opposite ends, and the two rotating shafts are movably connected to the two side frames by bearings. The second stepper motor is fixedly installed on one side of one of the side frames, and the output shaft end of the second stepper motor is fixedly connected to one of the rotating shafts.
[0008] Furthermore, one end of the hollow column is fixedly connected to the main body of the steel blade ring, the gear ring is fixedly sleeved on the hollow column, and the bottom of the gear ring meshes with the gear rod. The first stepper motor is fixedly installed on the mounting bracket, and the output shaft end of the first stepper motor is fixedly connected to the gear rod.
[0009] Furthermore, the piston rod end of the hydraulic cylinder is fixedly connected to the mounting bracket, and the hydraulic cylinder is located at the bottom of the first stepper motor. The other end of the hydraulic cylinder is fixedly connected to a T-shaped plate, and the bottom end of the T-shaped plate is fixedly connected to the first bracket.
[0010] Furthermore, the opposing sides of the two sliders are fixedly connected to the mounting bracket, and the back sides of the two sliders extend into the two sliding frames respectively.
[0011] As can be seen, in the above technical solution, the two mounting brackets drive the four sliders to slide within the four sliding frames, which can further improve the stability of the two mounting brackets.
[0012] Furthermore, the mounting bracket is movably provided with two sliding rods, and the two ends of the two sliding rods are respectively fixedly connected to the side frame and the T-shaped plate.
[0013] As can be seen, in the above technical solution, the four sliding rods can limit the two mounting brackets to improve their stability.
[0014] Furthermore, a positioning component is provided on the top of the main body of the wood mold cutter. The positioning component includes a rubber pad roller and a third stepper motor. Both ends of the rubber pad roller are movably connected to the second bracket through bearings. The third stepper motor is fixedly installed on one side of the second bracket, and the output shaft end of the connecting column is fixedly connected to the rubber pad roller.
[0015] Furthermore, a grinding roller is provided on the top of the rubber pad roller, and both ends of the grinding roller are fixedly connected to the second bracket.
[0016] Furthermore, both mounting brackets are provided with positioning components, each of which includes two magnetic strips and a Hall sensor. The top of the Hall sensor is fixedly connected to the mounting bracket, and the two magnetic strips are respectively fixedly installed at the bottom of the first bracket and the side frame.
[0017] The technical effects and advantages of this invention are as follows:
[0018] 1. This invention uses a third stepper motor to drive the rubber pad roller to rotate at a constant speed. Two first stepper motors drive two steel blade ring bodies to rotate, and the two steel blade ring bodies and two rubber pad rollers are used to die-cut the cardboard. The piston rods on the two hydraulic cylinders extend and drive the two mounting frames to move in opposite directions. The second stepper motor drives the wooden die-cutting body to rotate, and the wooden die-cutting body and rubber pad rollers are used to die-cut the cardboard. The operation is simple, with a dual die-cutting mode and a wide range of applications.
[0019] 2. This invention uses a rubber pad roller to simultaneously clamp the cardboard and move it, preventing the cardboard from shifting during the cutting process. The grinding action of the grinding belt on the grinding roller polishes the dents, burrs and residual paper scraps on the surface of the rubber pad roller, restoring the rubber pad roller to a flat and smooth working surface. The structure is simple and easy to use.
[0020] 3. In this invention, the Hall sensor is moved horizontally by the mounting bracket. When the Hall sensor moves to the position directly above one of the magnetic strips, the Hall sensor senses the magnetic field signal of the magnetic strip and converts it into an electrical signal, which is transmitted to the equipment control terminal. After receiving the electrical signal, the control terminal determines that the steel blade ring assembly has moved to the preset working position and then issues a command to control the hydraulic cylinder to stop moving, thereby achieving precise positioning of the working position of the steel blade ring assembly.

[0029] Example 1
[0030] Refer to the instruction manual appendix Figure 1-5 The dual-purpose die-cutting structure of this embodiment includes a first support 1, a second support 2, and two side frames 3. One side of each side frame 3 is fixedly connected to the first support 1 and the second support 2, respectively, and the second support 2 is located on top of the first support 1. Sliding frames 4 are fixedly connected to both the front and rear sides of each side frame 3. A wood die-cutting knife assembly 8 for processing cardboard is provided between the two side frames 3. The wood die-cutting knife assembly 8 includes a wood die-cutting knife body 801, two connecting columns 802, two rotating shafts 803, a second stepper motor 804, and multiple fixing bolts 805.
[0031] The outer side of the wood mold cutter body 801 is provided with two steel blade ring assemblies 7 for processing cardboard. Each steel blade ring assembly 7 includes a steel blade ring body 701, a hollow column 702, a mounting bracket 703, a gear ring 704, a gear rod 705, a first stepper motor 706, a hydraulic cylinder 707, and two sliders 708.
[0032] The two sides of the main body 801 of the wood mold cutter are fixed to the two connecting columns 802 by multiple fixing bolts 805. The two rotating shafts 803 are fixedly connected to the two connecting columns 802 at their opposite ends, and the two rotating shafts 803 are movably connected to the two side frames 3 by bearings. The second stepper motor 804 is fixedly installed on one side of one of the side frames 3, and the output shaft end of the second stepper motor 804 is fixedly connected to one of the rotating shafts 803.
[0033] One end of the hollow column 702 is fixedly connected to the steel blade ring body 701. The gear ring 704 is fixedly sleeved on the hollow column 702, and the bottom of the gear ring 704 meshes with the gear rod 705. The first stepper motor 706 is fixedly installed on the mounting bracket 703, and the output shaft end of the first stepper motor 706 is fixedly connected to the gear rod 705.
[0034] The piston rod end of the hydraulic cylinder 707 is fixedly connected to the mounting bracket 703, and the hydraulic cylinder 707 is located at the bottom of the first stepper motor 706. The other end of the hydraulic cylinder 707 is fixedly connected to a T-shaped plate 6, and the bottom end of the T-shaped plate 6 is fixedly connected to the first bracket 1. The opposing sides of the two sliders 708 are fixedly connected to the mounting bracket 703, and the opposing sides of the two sliders 708 extend into the two slide frames 4 respectively.
[0035] Refer to the instruction manual appendix Figure 1-2 The mounting bracket 703 has two sliding rods 5 that are movably installed, and the two ends of the two sliding rods 5 are fixedly connected to the side frame 3 and the T-shaped plate 6 respectively.
[0036] Refer to the instruction manual appendix Figure 1-3 The top of the wood mold cutter body 801 is provided with a positioning component 9, which includes a rubber pad roller 901 and a third stepper motor 902. Both ends of the rubber pad roller 901 are movably connected to the second bracket 2 through bearings. The third stepper motor 902 is fixedly installed on one side of the second bracket 2, and the output shaft end of the connecting column 802 is fixedly connected to the rubber pad roller 901.
[0037] Refer to the instruction manual appendix Figure 1 and 5 Both mounting brackets 703 are equipped with positioning components. Each positioning component includes two magnetic strips 11 and a Hall sensor 12. The top of the Hall sensor 12 is fixedly connected to the mounting bracket 703. The two magnetic strips 11 are respectively fixedly installed at the bottom of the first bracket 1 and the side frame 3.
[0038] The usage method of this embodiment is as follows:
[0039] In use, the first bracket 1 and the two side frames 3 are installed on the ground by multiple expansion screws. The cardboard is placed between the rubber pad roller 901 and the two steel blade ring bodies 701. The third stepper motor 902 and the two first stepper motors 706 are started simultaneously. The third stepper motor 902 drives the rubber pad roller 901 to rotate at a constant speed. At the same time, the two first stepper motors 706 drive the two gear rods 705 to rotate. Since the two gear rods 705 mesh with the two gear rings 704 respectively, the two gear rods 705 can drive the two gear rings 704 and the two hollow columns 702 to rotate, thereby driving the two steel blade ring bodies 701 to rotate. The cardboard is die-cut by the two steel blade ring bodies 701 and the two rubber pad rollers 901.
[0040] When the third stepper motor 902 is turned off, the two hydraulic cylinders 707 are started simultaneously. The piston rods on the two hydraulic cylinders 707 extend and drive the two mounting brackets 703 to move in opposite directions, thereby driving the two hollow columns 702 and the two steel blade ring bodies 701 to move in opposite directions. At the same time, the four sliding rods 5 can limit the two mounting brackets 703 to improve their stability. Meanwhile, the two mounting brackets 703 drive the four sliders 708 to slide in the four sliding frames 4 respectively, which can further improve the stability of the two mounting brackets 703. Finally, the two steel blade ring bodies 701 move into the two side frames 3 respectively.
[0041] Next, place the wood die-cutting blade body 801 between the two connecting posts 802, and fix the wood die-cutting blade body 801 and the two connecting posts 802 together with multiple fixing bolts 805. Simultaneously start the second stepper motor 804 and the third stepper motor 902. The second stepper motor 804 drives the two rotating shafts 803 to rotate, thereby driving the two connecting posts 802 and the wood die-cutting blade body 801 to rotate. The wood die-cutting blade body 801 and the rubber pad roller 901 perform die-cutting on the cardboard. The operation is simple, with a dual die-cutting mode and a wide range of applications.
[0042] Simultaneously, the mounting bracket 703 drives the Hall sensor 12 to move horizontally. When the Hall sensor 12 moves to the position directly above one of the magnetic strips 11, the Hall sensor 12 senses the magnetic field signal of the magnetic strip 11 and converts it into an electrical signal, which is transmitted to the equipment control terminal. After receiving the electrical signal, the control terminal determines that the steel blade ring assembly 7 has moved to the preset working position, and then issues a command to control the hydraulic cylinder 707 to stop moving, thereby achieving precise positioning of the working position of the steel blade ring assembly 7.
[0043] Similarly, when the Hall sensor 12 moves to a position directly above another magnetic strip 11, the Hall sensor 12 senses the magnetic field signal of the magnetic strip 11 and converts it into an electrical signal, which is transmitted to the device control terminal. After receiving the electrical signal, the control terminal determines that the steel blade ring assembly 7 has moved to the preset storage position, and then issues a command to control the hydraulic cylinder 707 to stop moving, thereby achieving precise positioning of the steel blade ring assembly 7 in the storage position.
[0044] Example 2
[0045] Refer to the instruction manual appendix Figure 2-3 Based on Example 1, this example provides a two-in-one die-cutting structure: a grinding roller 10 is provided on the top of the rubber pad roller 901, and both ends of the grinding roller 10 are fixedly connected to the second bracket 2.
[0046] The usage method of this embodiment is as follows:
[0047] During use, the rubber pad roller 901 can simultaneously clamp the cardboard and drive it to move, preventing the cardboard from shifting during the cutting process. The grinding roller 10 consists of a roller body and a grinding belt covering the surface of the roller body. When the die-cutting rubber pad is working, it will have uneven surface and uneven wear due to repeated squeezing by the blade and paper scraps sticking together. Through the cutting action of the grinding belt on the grinding roller 10, the depressions, burrs and residual paper scraps on the surface of the rubber pad roller 901 are polished, so that the rubber pad roller 901 restores a flat and smooth working surface. The structure is simple and easy to use.

Electrical control components not mentioned in this technical solution are not shown in the figures because they are existing technologies, and will not be described here.
[0049] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention.
