Description

Technical Field

[0001] This invention discloses a cardboard die-cutting machine and its control method, belonging to the field of printing equipment. Background Technology

[0002] A die-cutting machine applies pressure using a printing plate to cut printed materials or cardboard into specific shapes. It is an important piece of equipment for post-printing packaging processing.

[0003] During die-cutting, the equipment completes the die-cutting process by transferring the cardboard to the printing plate area of ​​the die-cutting machine and then outputting the cardboard. During the transfer of the cardboard, the feeder at the feeding end of the equipment uses suction to grab the cardboard onto the conveyor belt, and then works with the brush rollers and rubber rollers above the conveyor belt to continue conveying the cardboard forward. In the first half of the conveying, only the flat rubber rollers are usually used to convey the cardboard. In the second half of the conveying, brush rollers with brushes on their surfaces are used for conveying. Before the operation, the position of the brush rollers needs to be manually adjusted to the edge of the cardboard according to the size of the cardboard. At this time, the height of the brush rollers is not flush with the top surface of the cardboard, but is lowered to contact the side of the cardboard so that the brush rollers can use the side thickness of the cardboard to provide a forward pushing force. However, when conveying the cardboard, if the brush rollers are placed at the edge of the cardboard, it is easy for the brush rollers to lift the cardboard along the edge, resulting in the cardboard delamination. If the brush rollers are placed directly above the cardboard and flush with it, it is easy for the cardboard to not be conveyed smoothly due to the low surface friction.

[0004] In response to the above problems, a new improvement plan is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a cardboard die-cutting machine to solve the above-mentioned problems.

[0006] The present invention achieves the above-mentioned objective through the following technical solution: a cardboard die-cutting machine, comprising:

[0007] The machine is used to transport materials and to die-cut materials. The machine is divided into a feeding area, a feeding area and an operating area.

The operation panel is fixedly mounted on the control box, and a motherboard is provided between the operation panel, the processor, and the signal terminal to form a signal connection between them.

[0016] The controller controls the auxiliary device, de-icing device, power component, micro motor and transmission mechanism through the operation panel. The processor processes the data obtained from the operation panel. After receiving the signal from the operation panel, the processor sends a signal to the signal terminal, which then sends the signal to the auxiliary device, power component and micro motor respectively.

[0017] Preferably, the transmission mechanism includes a lifting component and a translation component. The translation component includes several tracks, which are fixedly connected to the lifting component. Several moving parts are slidably arranged on each track, and a paper pressing wheel is fixedly connected to each moving part.

[0018] Preferably, the lifting assembly includes a hydraulic cylinder and a support plate, the hydraulic cylinder is fixedly connected to the machine base, the support plate is fixedly connected to the output end of the hydraulic cylinder, and the track is fixedly connected to the support plate.

[0019] Preferably, the guide includes a fixed part and a swinging part. The fixed part is fixedly connected to the ice crusher and communicates with the outlet of the ice crusher. The swinging part is rotatably connected to the fixed part. A pusher is fixedly connected to the machine base. The pusher is electrically connected to the controller. The output end of the pusher can abut against the swinging part for transmission.

[0020] Preferably, a limiting plate is fixedly connected to the swing part, and the limiting plate can abut against the fixed part for limiting.

[0021] Preferably, the collection box includes an upper layer and a lower layer, a partition with drainage holes is fixedly provided between the upper layer and the lower layer, the filter element is only connected to the upper layer, and a pull box is slidably provided in the lower layer.

[0022] Preferably, the machine platform has several water leakage channels in the feeding area, a circulating water tank is installed in the feeding area, the water leakage channels are connected to the circulating water tank, a circulating water pump is fixedly connected to the machine platform, the circulating water tank is connected to the ice maker through the circulating water pump, and the circulating water pump is electrically connected to the controller.

[0023] Preferably, a pressure sensor is installed inside the machine, the pressure sensor is used to monitor the weight of the circulating water tank, and the pressure sensor is electrically connected to the controller.

[0024] A control method for a cardboard die-cutting machine includes the following steps:

[0025] Step 1: Prepare materials. Move the cardboard that needs to be die-cut to the feeding area and wait. Then add clean water to the water tank.

[0026] Step 2: Use the controller to start the active water pump and ice maker, so that water is injected into the ice maker and ice making begins;

[0027] Step 3: Input the thickness and width information of the cardboard into the controller, and use the controller to adjust the position of the pressure rollers through the transmission mechanism to achieve the pre-positioning effect;

[0032] Compared with the prior art, the beneficial effects of the present invention are:

[0033] During the paperboard conveying process, the ice crusher spreads crushed ice onto the surface of the paperboard placed on the conveyor belt through the guide. Based on the principle of spreading gravel on roads and railways to increase the friction between the tires and the road, the crushed ice acts as gravel, increasing the friction between the rubber wheels and the paperboard surface, thereby stabilizing the paperboard transmission and avoiding paper jams.

[0034] The position of the pressure rollers is adjusted by translation and lifting components, and the control is automatic, eliminating the need for manual adjustment and improving both efficiency and accuracy.

[0035] The ice fragments collected by the de-icing device, as well as those falling into the circulating water tank, can be reused after melting. Attached Figure Description

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. In this description, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] like Figure 1 , Figure 2 , Figure 8 As shown, a cardboard die-cutting machine includes:

[0048] Machine 1 is used for conveying and die-cutting materials. Machine 1 is divided into a feeding area 101, a feeding zone 102, and a working area 103. The feeding area 101 is for placing the cardboard to be die-cut. The feeding area 101 integrates a feeder, which uses suction cups to grab the cardboard and transport it to the next area. This is a common setting for die-cutting machines and will not be described in detail here. The feeding zone 102 is the area for conveying the cardboard, and the working area 103 is the area for die-cutting the cardboard. Several power units 2 are installed on the feeding zone 102. The power units 2 have... The body is set as an electrically driven rotating shaft, and several paper conveying belts 3 are connected to the power component 2 at intervals. When the equipment is running, the rotating shaft starts to rotate and drives the paper conveying belts 3 to move. At this time, the paperboard that is grabbed by the suction cup from the feeding area 101 and put onto the paper conveying belt 3 will be conveyed forward by the paper conveying belt 3 to the working area 103. The working area 103 integrates a conveyor belt for continuing to convey the paperboard forward and a die-cutting mold. After the paperboard is fed into the working area 103, the die-cutting mold will contact the paperboard and die-cut it. Then the paperboard will continue to be conveyed to the next area.

[0049] The pressure roller 6 is used to press the material and cooperate with the paper conveyor belt 3 to transport the material. It includes a support 61, a rubber roller 62 and a micro motor 63. The rubber roller 62 is rotatably connected to the support 61, and the output end of the micro motor 63 is fixedly connected to the rubber roller 62. The purpose of the pressure roller 6 is to ensure the stability of the paperboard during the conveying process and to ensure that it can enter the working area 103 along the prescribed path to complete the die cutting. If there is no pressure roller 6, the paperboard will deviate, and the shape after die cutting will not meet the requirements.

[0050] The transmission mechanism is used to cause the paper pressing roller 6 to move within the feeding zone 102;

[0051] An auxiliary device is used to spread crushed ice on the surface of the material on the paper conveyor belt 3 to increase the friction between the rubber wheel 62 and the surface of the material.

[0052] The de-icing device is used to remove residual ice fragments from the surface of the cardboard conveyed to the designated location, so as to prevent ice fragments from remaining on the surface of the cardboard after the operation is completed;

[0053] The controller 7 is used to control the power component 2, auxiliary devices, de-icing device, transmission mechanism and micro motor 63;

[0054] The auxiliary equipment includes an ice crusher 4, an ice maker 13, a water tank 15, and an active water pump 16. The ice crusher 4 is fixedly installed on the feeding area 101. A guide 5 is fixedly connected to the discharge end of the ice crusher 4, with the guide 5 facing the paper conveyor belt 3. The ice maker 13 and the water tank 15 are both fixedly installed on the feeding area 101. The water tank 15 is connected to the ice maker 13 through the active water pump 16. The discharge end of the ice maker 13 faces the feed end of the ice crusher 4. Before operation, ice is made using the ice maker 13 and added to the ice crusher 4. When operation begins, the ice crusher 4 crushes the ice into small particles. Existing ice crushers 4 have... Multiple types are available, and the size of the ice crusher particles can be selected. The crusher has excellent performance. Those skilled in the art can select the appropriate type of ice crusher 4 according to actual needs. The crushed ice will fall out from the outlet of the ice crusher 4 and fall along the guide 5. Since the guide 5 is facing the paper conveyor belt 3, the cardboard entering the paper conveyor belt 3 from the feeding area 101 will be covered with crushed ice. In conjunction with the paper pressing roller 6 pressing against the cardboard, based on the principle of spreading gravel on roads and railways to increase the friction between the tires and the road, the crushed ice acts as gravel, which increases the friction between the rubber roller 62 and the cardboard surface, thereby stably transmitting the cardboard and avoiding paper jams.

[0055] The de-icing device includes a suction nozzle 17, an extension tube 18, a collection box 19, a filter element 20, and a power system 21. Specifically, the power system 21 is a motor that drives a fan to rotate at high speed to generate negative pressure, so that the suction nozzle 17 can suck away the ice fragments on the surface of the cardboard. The filter element 20 is used to prevent ice fragments from staying in the collection box 19 and to allow air to pass through to form a circulation. The suction nozzle 17 is fixedly connected to the machine base 1 and spans all the paper conveyor belts 3. One end of the extension tube 18 is fixedly connected to the suction nozzle 17 and the other end is fixedly connected to the collection box 19. One end of the filter element 20 is fixedly connected to the collection box 19 and the other end is fixedly connected to the power system 21. During the operation of the equipment, when the cardboard is transported to the work area 103 to be die-cut, the suction nozzle 17 located at the entrance of the work area 103 will suck away the ice fragments on the surface of the cardboard to prevent too much ice fragments from remaining on the surface of the cardboard and melting.

[0056] The controller 7 includes a control box 71, an operation panel 72, a processor, and a signal terminal. The operation panel 72 is fixedly mounted on the control box 71. A main board is provided between the operation panel 72, the processor, and the signal terminal to form a signal connection between them.

[0057] The controller 7 controls the auxiliary device, de-icing device, power component 2, micro motor 63, and transmission mechanism via the operation panel 72. The processor processes the data obtained from the operation panel 72. After receiving the signal from the operation panel 72, the processor sends a signal to the signal terminal, which then sends the signal to the auxiliary device, power component 2, and micro motor 63 respectively. Specifically, the size and thickness information of the cardboard are input via the control panel. The control panel converts the input data into corresponding instructions and sends them to the transmission mechanism via the signal terminal. The transmission mechanism adjusts the position of the paper pressure roller 6. The conveying speed is then input via the operation panel 72. The control panel converts the input data into corresponding instructions and sends them to the power component 2 and micro motor 63 via the signal terminal, enabling them to convey the paper at a preset speed. The board is then fed into the ice maker 13 by the controller 7 starting the active water pump 16 to inject water into the ice maker 13. The ice maker 13 then starts to generate ice. After the ice is generated, the ice maker 13 opens the discharge end, allowing the ice inside to fall into the ice crusher 4. The ice crusher 4 is then started to crush the ice into small pieces. After the ice crusher 4 starts to produce crushed ice, the cardboard in the feeding area 101 is transported onto the paper conveyor belt 3 and moves towards the working area 103 with the pressure rollers 6 for die-cutting. At the same time, when the cardboard is about to enter the working area 103, the surface crushed ice will be sucked away by the de-icing device. Because the crushed ice acts as gravel to increase friction, the pressure rollers 6 of this equipment are all made of relatively flat rubber rollers 62, which can stably transport the cardboard. The cardboard edges will not be scratched and delaminated due to the setting of brush rollers.

[0058] like Figure 1 and Figure 3 As shown, the transmission mechanism includes a lifting assembly 8 and a translation assembly 9. The translation assembly 9 includes several tracks 91, which are fixedly connected to the lifting assembly 8. Several movers 92 are slidably arranged on any track 91, and a paper pressing wheel 6 is fixedly connected to any mover 92. The translation assembly 9 of this product is specifically configured as a linear motor, which is a linear motor with multiple movers 92. Under power control, the movers 92 can move along the linear track 91 and drive the paper pressing wheel 6 fixedly connected to it to move, thereby adjusting the position of the paper pressing wheel 6.

[0059] like Figure 1 and Figure 4 As shown, the lifting assembly 8 includes a hydraulic cylinder 81 and a support plate 82. The hydraulic cylinder 81 is fixedly connected to the machine base 1, the support plate 82 is fixedly connected to the output end of the hydraulic cylinder 81, and the track 91 is fixedly connected to the support plate 82. When adjusting the height of the paper pressing roller 6, the controller 7 drives the hydraulic cylinder 81 to rise or fall according to the paperboard thickness input by the operator, thereby driving the support plate 82 and the various components fixedly connected to the support plate 82 to perform lifting and lowering movements, thereby achieving the purpose of adjusting the height of the paper pressing roller 6 to adapt to paperboards of various thicknesses.

[0060] like Figure 5 , Figure 6 As shown, the guide 5 includes a fixed part 51 and a swinging part 52. The fixed part 51 is fixedly connected to the ice crusher 4 and communicates with the outlet of the ice crusher 4. The swinging part 52 is rotatably connected to the fixed part 51. A pusher 10 is fixedly connected to the machine base 1. The pusher 10 can be configured as a hydraulic or pneumatic push rod. The pusher 10 is electrically connected to the controller 7. The output end of the pusher 10 can abut against the swinging part 52 for transmission. When the output end of the pusher 10 extends forward, the swinging part 52 is pushed forward and rotates on the fixed part 51. Conversely, when the output end of the pusher 10 retracts, the swinging part 52 will rotate and reset under the action of gravity. When the equipment starts to run, ice crusher 4 produces crushed ice, which falls out along the outlet of ice crusher 4 onto the guide 5. The crushed ice first falls onto the fixed part 51 of the guide 5. Then, the ice blocks roll down along the inclined fixed part 51. After passing the fixed part 51, the ice blocks will fall onto the swing part 52. At this time, the swing part 52 is pushed by the pusher 10 and swings back and forth continuously, thereby creating a scattering effect on the ice blocks, so that it can cover a larger area. In addition, a limit plate 53 is fixedly connected to the swing part 52. The limit plate 53 can abut against the fixed part 51 to limit the movement. By setting the extended limit plate 53, when the swing part 52 rotates, the ice blocks falling from the fixed part 51 will not fall out from the gap of rotation, but will be blocked by the limit plate 53, thereby ensuring that the ice blocks will definitely fall into the swing part 52 through the fixed part 51. Secondly, when the swing part 52 resets, the limit plate 53 abuts against the fixed part 51 to limit the movement of the swing part 52.

[0061] like Figure 9 As shown, the collection box 19 includes an upper layer and a lower layer. A partition 22 with drainage holes is fixedly installed between the upper and lower layers. The filter element 20 is only connected to the upper layer. A pull box 23 is slidably installed in the lower layer. By dividing the collection box 19 into two layers using the partition 22 with drainage holes, the crushed ice will only stay in the upper layer when it is sucked into the collection box 19. When the crushed ice melts, the ice water will flow from the partition 22 into the pull box 23 in the lower layer. The operator can manually pull out the pull box 23 to reuse this water.

[0062] like Figure 7As shown, the machine 1 has several water leakage channels 11 on the feeding area 102. A circulating water tank 12 is installed in the feeding area 102. The water leakage channels 11 are connected to the circulating water tank 12. A circulating water pump 14 is fixedly connected to the machine 1. The circulating water tank 12 is connected to the ice maker 13 through the circulating water pump 14. The circulating water pump 14 is electrically connected to the controller 7. Since the paper conveyor belt 3 of this equipment is arranged at intervals, and since the equipment will scatter ice blocks when conveying paperboard, some ice blocks will fall into the machine 1 along the intervals between the paper conveyor belt 3 or fall directly into the water leakage channel 11. When they melt, they will flow into the circulating water tank 12 along the water leakage channel 11 on the machine 1 for storage, which achieves the effect of partial recycling. When a certain amount of melted water is collected in the circulating water tank 12, the controller 7 can be used to control the circulating water pump 14 to transport the water to the ice maker 13 to form ice blocks again for subsequent ice crushing.

[0063] Finally, optionally, a pressure sensor is installed in the machine 1 of this product. The pressure sensor is used to monitor the weight of the circulating water tank 12. The pressure sensor is electrically connected to the controller 7. By setting the pressure sensor to monitor the weight data of the circulating water tank 12, the amount of water accumulated in the circulating water tank 12 can be analyzed and this information can be fed back to the controller 7, which is beneficial for timely use of the water source in the circulating water tank 12.

[0064] A control method for a cardboard die-cutting machine includes the following steps:

[0065] Step 1: Prepare materials. Move the cardboard that needs to be die-cut to the feeding area 101 and wait. Then add clean water to the water tank 15.

[0066] Step 2: Use controller 7 to start active water pump 16 and ice maker 13, so that water is injected into ice maker 13 and ice making begins;

[0067] Step 3: Input the thickness and width information of the cardboard into the controller 7. Use the controller 7 to adjust the position of the pressure roller 6 through the transmission mechanism to ensure that the rubber roller 62 in the pressure roller 6 can abut against the surface of the cardboard, prevent skewing during the conveying process, and achieve the effect of pre-positioning.

[0068] Step 4: Input the speed data of the paperboard to the controller 7, and use the controller 7 to send the corresponding instructions to the power unit 2 and the micro motor 63 so that the paperboard can be transported at the preset speed.

[0069] Step 5: After the ice maker 13 in Step 1 has finished making ice, start the equipment using the controller 7. After the equipment is started, the ice cubes in the ice maker 13 fall into the ice crusher 4 and are crushed by the ice crusher 4 and then sprinkled down along the guide 5. At the same time, the cardboard in the feeding area 101 is grabbed onto the paper conveyor belt 3. Specifically, the suction cup feeder integrated in the feeding area 101 of the equipment grabs the cardboard for feeding, and moves forward with the pressure roller 6. The existing ice maker 13 can already be controlled by electronic control to control whether to spit out ice cubes. Therefore, it can be used with the controller 7 of this product for circuit control to achieve the effect of controlling the spitting out of ice cubes.

[0070] Step 6: Use controller 7 to start pusher 10, which will drive swing part 52 of guide plate to swing back and forth, so as to scatter crushed ice.

[0071] Step 7: The controller 7 calculates the water volume in the circulating water tank 12 based on the data from the pressure sensor. If there is a large amount of water in the circulating water tank 12, the circulating water pump 14 is started. The circulating water pump 14 is used to transport the melted water in the circulating water tank 12 to the ice maker 13 for ice making, which is more energy-efficient and environmentally friendly.

[0072] Working principle: The operator first places the stacked cardboard raw materials in the feeding area 101, and then inputs the cardboard dimensions for this die-cutting, including length, width, and thickness, into the control panel 72 of the controller 7. Based on the cardboard dimensions, length, and thickness, the controller 7 uses the transmission mechanism to adjust the pressure rollers 6 to the appropriate position and height. Then, based on the width dimension, the controller selects how many sets of pressure rollers 6 to use for auxiliary conveying in the width direction. After the parameters are set, the controller 7 operates the active water pump 16 and the ice maker 13 to start generating ice blocks using the control panel 72. After the ice blocks are generated, a command is sent to the ice maker 13 to discharge ice blocks into the feed inlet of the ice crusher 4. After the equipment starts, the ice crusher 4 starts to throw ice blocks towards the paper conveyor belt 3. The surface of the cardboard entering the feeding area 102 from the feeding area 101 will be covered with ice blocks. Using the ice blocks as gravel, the cardboard as a road, and the rubber rollers 62 as car tires, the friction is increased, and the stability of the conveying process is improved.
