Description

Technical Field

[0001] The present invention relates to the technical field of full-automatic die-cutting machines, in particular to a full-automatic die-cutting machine for printing and packaging. Background Art

[0002] Existing die-cutting machines are generally divided into flatbed die-cutters and rotary die-cutters. Cardboard used in die-cutting machines generally undergoes two processes: printing and laminating. Existing die-cutting machines are already highly automated, with the main working steps being loading, positioning, die-cutting, waste removal, and collection, all completed automatically by the machine. However, existing fully automatic die-cutting machines still require manual supervision. Since the die-cutting machine's loading unit is generally refilled manually, when the material on the loading unit is consumed, the printed material needs to be transported to the loading unit by forklift for refilling. Therefore, an operator is required for every few machines. After the operator uses the forklift to place the material on the lifting platform, the remaining steps are completed automatically by the machine. In such an environment, in order to meet the working rhythm of the die-cutting machine and improve work efficiency, a certain amount of labor costs are required.

[0003] To this end, a fully automatic die-cutting machine for printing and packaging is proposed. The materials that have been laminated at the laminating machine are automatically conveyed to the loading unit through a conveyor belt. The loading unit will automatically align the material stacks. After the loading unit has consumed all the materials, the loading unit and the loading unit will be replaced to realize automatic material replenishment of the die-cutting machine, which not only reduces labor costs but also improves work efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a fully automatic die-cutting machine for printing and packaging, which automatically transports materials to the loading unit through a conveyor belt. The loading unit will automatically align the material stack. After the loading unit consumes all the materials, the loading unit and the loading unit will be replaced to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A fully automatic die-cutting machine for printing and packaging, comprising:

[0007] The loading unit includes a machine top, a plurality of support columns are installed at the corners of the bottom wall of the machine top, a feeder for loading is installed on the machine top, a transport positioning unit for transporting and automatically correcting materials is installed on one side of the loading unit, partitions perpendicular to it are installed on both sides of the transport positioning unit, a die-cutting unit is installed on the side of the transport positioning unit away from the loading unit, a waste cleaning unit for removing waste materials adhered to the material after die-cutting is installed on the side of the die-cutting unit away from the transport positioning unit, and a collection unit for collecting die-cut products is installed on the side of the waste cleaning unit away from the die-cutting unit.

[0008] Before starting the existing automatic die-cutting machine, the operator will use a forklift to transport the stacked materials to the lifting platform directly below the feeder device. After starting the automatic die-cutting machine, the feeder will automatically transport the materials to the transport positioning unit at a fixed rhythm. The transport positioning unit will transport the materials to the front of the die-cutting unit. In front of the die-cutting unit, the transport positioning unit will correct the materials so that the materials enter the die-cutting unit at a fixed position to prevent the materials from shifting when the die-cutting unit is die-cutting. There will be waste materials stuck to the materials after die-cutting. At this time, the waste removal unit is required to remove and collect the waste materials. At this time, the materials have become finished products, and the collection unit will collect the finished products.

[0009] However, when the material on the loading unit is consumed, it needs to be replenished manually, so an operator is required for every few machines. Therefore, if the working efficiency of the die-cutting machine needs to be met, a certain amount of labor cost will be required.

[0010] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion. The transmission gear of said sliding panel also is provided with a set of movable lids, and said movable lid is provided with a set of movable lids, and said movable lid is provided with a set of movable lids, and a plurality of movable lids are arranged on said movable panel.

[0011] The support base is divided into three areas. The middle part cooperates with the feeder to form the loading area, and the storage plates on both ends cooperate with the conveyor belt to form the feeding area. The bottom plate on the support base is moved by the reversible motor and the screw drive. The length of the bottom plate is 2 / 3 of the length of the support base. When the bottom plate is at any extreme position, half of the bottom plate will always be in the loading area and the other half will be in the feeding area. The servo motor on the movable plate in the loading area will work with the feeder to gradually raise the height of the placement plate so that the feeder can feed normally. When the servo motor in the loading area starts for a set time, the placement plate rises to the highest point. At this time, the material in the loading area has been consumed. The control system controls the rotary die-cutting and conveyor belts to stop starting. The reversible motor starts for a set time to move the movable plate in the loading area to the feeding area. The movable plate in the feeding area moves to the loading area, and then the die-cutting machine is started. Conveyor belt 2 will transport the materials to the diverter device. The diverter device will divert the materials according to whether the feeding area is on the placement plate and transport them to the corresponding conveyor belt 1. Conveyor belt 1 transports the materials to the placement plate in the feeding area. The highest point of the placement plate is 5cm lower than the upper surface of the conveyor belt, so the materials will gradually accumulate on the placement plate. The control system will control the servo motor to start at regular intervals according to the correct speed to lower the placement plate by 5cm. After a set number of reciprocating cycles, the filling is completed, the control system turns off the conveyor belt, and waits for the material in the loading area to be consumed. The present invention only shows part of the conveyor belt, which can be changed according to actual needs.

[0012] In order to prevent the servo motor 1 from continuing to start after the placement plate reaches the limit position due to transmission error, which may eventually damage the screw 2 or the placement plate, a proximity switch is installed on the top of the movable plate and the guide column. When the placement plate contacts the proximity switch, the servo motor 1 stops starting and the control system ends the command to control the placement plate to move downward.

[0013] Preferably, the lifting device includes multiple hydraulic cylinders installed at the corners of the bottom wall of the base plate, and the corners of the base plate are provided with multiple through holes that cooperate with the output ends of the hydraulic cylinders, and each output end of the hydraulic cylinders is connected to the movable plate.

[0014] In order to prevent the guide column or material from interfering with the feeder when the base plate is moving, a hydraulic cylinder is installed at the corner of the base plate, and the movable plate is installed on the hydraulic cylinder. Before the base plate moves, the hydraulic cylinder will retract to lower the movable plate, and the guide column, lead screw 2 and material height on the movable plate will also be lowered. When the base plate moves to the set position, the hydraulic cylinder will extend to raise the movable plate. After the movable plate is raised, the feeder and conveyor belt can be started.

[0015] Preferably, the steering device includes a mounting frame arranged in the middle of a conveyor belt, a through hole 2 is opened on the upper part of the mounting frame, a rotating shaft 1 is rotatably mounted in the through hole 2, a conveyor belt 3 is fixedly mounted on the end of the rotating shaft 1 located outside the mounting frame, a sprocket 1 is mounted on the end of the rotating shaft 1 close to the bottom wall of the mounting frame, a rack is mounted on the side of the bottom plate close to the mounting frame, a fixing plate is mounted on the side of the support seat close to the mounting frame, a rotating shaft 2 is vertically rotatably mounted on the fixing plate, a gear that cooperates with the rack is mounted on the rotating shaft 2, a sprocket 2 is mounted on the rotating shaft 2, and the sprocket 2 is located above the gear, and the sprocket 1 and the sprocket 2 cooperate with each other through a chain.

[0016] When the base plate moves, the rack on the base plate rotates the gear, which in turn rotates shaft 2, which in turn rotates sprocket 2. Sprocket 2, through the chain, drives sprocket 1, causing conveyor belt 3 to rotate synchronously. The transmission ratio between conveyor belt 3 and the base plate is: from the start of base plate movement to the stop, conveyor belt 3 rotates 180 degrees. Conveyor belt 3 transfers the material from conveyor belt 2 to conveyor belt 1. The conveying direction of conveyor belt 3 is fixed, so by coordinating with the rotation of the base plate as it moves, the material is always transferred to the corresponding conveyor belt 1 with the storage plate in the feeding area.

[0017] Preferably, a C-shaped plate is installed between the conveyor belt one, and the concave bottom wall of the C-shaped plate is flush with the height of conveyor belt three. There is a height difference between conveyor belt one, conveyor belt two and the steering device, which are conveyor belt two, conveyor belt three and conveyor belt one from high to low respectively. An arc-shaped baffle is installed above the vertical baffle, and the center of the arc-shaped baffle is located on the side close to the steering device. An arc-shaped baffle is installed on the top wall of the C-shaped plate, and the center of the arc-shaped baffle is located on the side close to conveyor belt two.

[0018] Because Conveyor 3's transport direction is perpendicular to Conveyor 1 and Conveyor 2, when the conveyor speed is increased to meet the refill rate, the coordination between Conveyor 3 and Conveyor 2 or Conveyor 1 may cause the material to rotate. If the conveyor belt width is less than the diagonal length of the material, the material may get stuck on the conveyor belt, affecting refill. Therefore, Conveyor 1, Conveyor 2, and Conveyor 3 are designed with different heights. The material on Conveyor 2 will only come into contact with Conveyor 3 after it has completely separated from Conveyor 3, and the material on Conveyor 3 will only come into contact with Conveyor 1 after it has completely separated from Conveyor 3. In this way, the material is not affected by both conveyor belts at the same time, and thus does not rotate.

[0019] The loading speed of each material in the loading unit is typically 1-2 seconds. Therefore, to meet the efficiency of the die-cutter, the conveyor belt speed must be very high. As the material falls from one conveyor belt to another, it may fly out of the range of the next conveyor belt due to inertia, so a baffle is required to contain the material. At Conveyor 3, because Conveyor 3 rotates, the baffle for Conveyor 3 cannot be installed on the side wall of Conveyor 3. Therefore, a C-shaped plate is installed between Conveyor 1. The C-shaped plate is located between Conveyor 3 and the feeder and aligns with the side wall of the C-shaped plate. The C-shaped plate effectively blocks the material from falling off the conveyor belt. The concave bottom wall of the C-shaped plate is flush with the height of Conveyor 3, and the length of the groove in the C-shaped plate is equal to the rotation diameter of Conveyor 3, so the C-shaped plate does not interfere with the rotation of Conveyor 3. A circular arc-shaped baffle is installed on the side wall of Conveyor 1 away from the deflection device to prevent the material conveyed from Conveyor 3 from flying out of the range of Conveyor 1. Because the material's kinetic energy is too great, using a vertical baffle to block it would cause significant impact and damage. However, a circular baffle can gradually redirect the material's forward motion. The central angle of the circular baffle of the present invention is 90°, so it shifts the material's horizontal movement into vertical motion, reducing the impact between the material and the baffle. A circular baffle is also mounted on the top wall of the C-shaped plate.

[0020] Preferably, the automatic alignment device includes a movable groove 2 provided on the bottom wall of the machine top, and the movable groove 2 is parallel to the movable groove 1, a screw 3 is rotatably installed in the movable groove 2, and guide shafts are installed on both sides of the screw 3. A servo motor 2 is installed on the outer wall of the machine top, and the output end of the servo motor is fixedly connected to one end of the screw 3. The screw 3 is composed of multiple sections of reverse threads, and four mounting plates that match the screw 3 are movably installed on the guide shaft, and two mounting plates are grouped together, and each group of the mounting plates is respectively located on the screw 3 with different steering threads, and the mounting plates are away from the other mounting plates in the same group. A cylinder is installed on the side wall of a mounting plate, and three through holes are provided on the mounting plate for the extension and retraction of the cylinder. A push plate is installed on the output end of the cylinder, and four through holes are provided on both sides of the three through holes. Guide rods that cooperate with the four through holes are installed at both ends of the push plate. Distance sensors for monitoring the height of materials are installed at both ends of the top and bottom walls of the machine. Hydraulic cylinders are installed on the partitions, and push plates are installed on the output ends of the hydraulic cylinders. Push plates are located between push plates, and push plates two and push plates one are at the same height. The push plates and curved plates are made of thermoplastic elastomer material.

[0021] Because the material falling from conveyor belt 1 onto the storage plate is uncontrollable, it is misaligned and oriented unevenly when stacked. Excessive deviation of the material on the storage plate will affect the correct positioning of the material by the feeder's loading and transport positioning units. Therefore, a movable slot 2 is provided on the bottom wall of the machine top, within which is mounted a lead screw 3 and a guide shaft. A movable plate is mounted on lead screw 3 and the guide shaft. Because lead screw 3 consists of multiple sections of threads rotating in opposite directions, and each set of mounting plates is located on threads with different rotational directions, when servo motor 2 is activated, the mounting plates will move toward or away from each other with the centerline of the storage plate as the center. A cylinder is mounted on the mounting plate, and a push plate 1 is mounted on the output end of the cylinder. The bottom wall of push plate 1 is flush with the upper surface of the storage plate at the maximum height. Servo motor 2 is activated to move the mounting plate to a set position. The pneumatic cylinders are then activated, and the cylinders on each set of fixed plates will synchronously extend and retract at a fixed frequency. When the cylinders extend and reach their limit, the distance between the push plates is 1-2 cm greater than the material length. Therefore, any material that falls onto the mounting plate is pushed to the center of the plate, aligning the material on both sides of the mounting plate. Hydraulic cylinder 2 is installed on the partition. Before refilling, hydraulic cylinder 2 is activated to move push plate 2 at the output end of hydraulic cylinder 2 to the set position. The distance between push plate 2 and conveyor belt 1 is equal to the material width. Material that falls onto the mounting plate from conveyor belt 1 stops moving upon contact with push plate 2, aligning the material on the conveyor belt.

[0022] At the beginning of feeding, the placement plate is at the highest point within the active range. At this time, the placement plate is 5 cm lower than the conveyor belt. As the material accumulates on the placement plate, the material height will gradually increase. When the material height exceeds the height of the conveyor belt, the feeding will be carried out. Only by the conveying speed of the conveyor belt to control the descent of the placement plate may have deviations, resulting in the inability to feed normally. Therefore, a distance sensor is installed on the top and bottom walls of the machine above the placement plate. When the distance between the material and the distance sensor reaches the set value, the control system will start the servo motor 1 to lower the placement plate by 5 cm. This cycle will be repeated until the placement plate drops to the lowest point.

[0023] When push plates 1 are aligning the material, if the push plates 1 on each set of mounting plates are not parallel, the distance between the push plates 1 may be partially less than the material length. In this case, when the cylinder extends, the push plates 1 may squeeze and damage the material. Therefore, guide rods are installed at both ends of the push plates 1. The guide rods are perpendicular to the mounting plates, ensuring that push plates 1 always remain parallel to the mounting plates. The mounting plates are kept parallel to each other by the guide shafts, so that each set of push plates 1 remains relatively parallel, preventing the material from being squeezed and damaged during the alignment process. The material made of thermoplastic elastomer combines the elasticity of rubber with the smooth texture of plastic. It can absorb some impact when the material contacts the push plates or arc-shaped baffles, reducing the possibility of material damage. Its smooth surface also does not affect material transportation.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. This invention adds two refilling zones on either side of the original loading zone. By translating the base plate and coordinating the vertical movement of the storage plates with a conveyor belt, while one storage plate works with the feeder to load the machine, the other plate works with the conveyor belt to refill. When the material in the loading zone is exhausted, a reversible motor drives the base plate to move the refilled plate to the loading zone and the empty plate to the refilling zone, thus achieving automatic refilling of the die-cutter. Automatic refilling not only reduces labor costs but also improves the efficiency of the die-cutter.

[0026] 2. Due to the high speed of the conveyor belt, the kinetic energy of the material will cause it to fly out of the range of the conveyor belt when it falls from one conveyor belt to another, affecting the refilling. The present invention blocks the material by installing an arc-shaped baffle on the conveyor belt. The arc-shaped baffle can gradually change the forward direction of the material. The central angle of the arc-shaped baffle of the present invention is 90°, so the arc-shaped baffle can change the horizontal movement of the material into vertical movement, reducing the impact between the material and the baffle. The arc-shaped baffle can protect the material from damage without ensuring the speed.

[0027] 3. The cylinder drives the push plate 1 to move back and forth, and the push plate 2 is limited, so that the material will be aligned and straightened after falling from the conveyor belt 1 to the placement plate, preventing the material from being too far away from the center of the placement plate and causing the feeder to be unable to load the material.

[0043] See also Figures 1 to 14 The present invention provides a fully automatic die-cutting machine for printing and packaging, and the technical solution is as follows:

[0044] Example 1, reference Figure 1 Only Figure 12 , when there is enough production space, conveyor belts can be installed to transport materials.

[0045] Before use, the length and width of the material are input into the control system. The control system will start the servo motor 2 15 and adjust the position of the mounting plate 38 according to the input information.

[0046] When the loading unit in the loading area is loading material and the storage plate 8 in the refilling area has finished refilling, the conveyor belt and cylinder 39 stop operating. When the material in the loading area is consumed, the die-cutter stops operating, and the control system controls hydraulic cylinder 1 21 to retract, causing movable plate 7 to descend 10 cm. After the descent is complete, the control system activates reversible motor 5, which drives screw 1 4, which in turn drives base plate 6 to move. As base plate 6 moves, rack 31 mounted on base plate 6 drives gear 33, which in turn drives shaft 2 28. Shaft 2 28 drives sprocket 2 30, which in turn drives sprocket 1 29 via chain 34. Sprocket 1 29 drives shaft 1 27 to rotate synchronously, and conveyor belt 3 20 rotates synchronously with it. The reversible motor 5 stops after running for a set time. At this time, the placement plate 8 in the loading area has moved to the feeding area, and the placement plate 8 filled with materials moves from the feeding area to the loading area. The conveyor belt three 20 rotates 180°. At this time, the material transported from the laminating machine by the conveyor belt two 19 will be transferred to another conveyor belt one 18 after passing through the conveyor belt three 20, and will cooperate with the placement plate 8 to feed the material. After the reversible motor 5 stops, the control system starts the hydraulic cylinder 1 21, and the hydraulic cylinder 1 21 extends to raise the movable plate 7 by 10 cm. After the hydraulic cylinder 1 21 stops running, the conveyor belt and the die-cutting machine restart. At this time, the servo motor 2 15 in the loading area will cooperate with the feeder. Since the feeder continuously feeds materials, the material height gradually decreases, and the servo motor 14 will run slowly, driving the bevel gear 2 12 to rotate, and the bevel gear 2 12 drives the bevel gear 1 11 to rotate, and the bevel gear 1 11 drives the screw 2 10 and the bevel gear 3 13 to rotate synchronously. After passing through the transmission shaft 17, the bevel gear 3 13 drives another bevel gear 11 to rotate, and the bevel gear 11 drives another screw 2 10 to rotate. Under the action of the two screws 2 10 and the guide column 9, the storage plate 8 slowly moves vertically upward, gradually raising the material height, so that the feeder can feed normally. In the refilling area, after hydraulic cylinder 1 (21) stops, the control system activates hydraulic cylinder 2 (22), moving push plate 2 (41) to a set position. The distance between push plate 2 (41) and conveyor belt 1 (18) is equal to the width of the material. Each piece of material stops moving after contacting push plate 2 (41). Therefore, each piece of material falls to the same position along conveyor belt 18. Cylinder 39 on mounting plate 38 then reciprocates at a fixed frequency, pushing the material to the center of storage plate 8 and aligning it. Storage plate 8's maximum height is 5 cm lower than conveyor belt 18. As the material accumulates on storage plate 8, its height increases. When distance sensor 25 detects that the distance between the material and storage plate 8 reaches the set value, servo motor 1 (14) in the refilling area activates, lowering storage plate 8 by 5 cm. This reciprocating cycle continues until storage plate 8 reaches its lowest position. When storage plate 8 reaches its lowest position, cylinder 39 and the conveyor belt stop, waiting for the material in the loading area to be consumed.

[0047] After using the automatic feeding device, the use of operators can be greatly reduced. Operators are no longer required to monitor material consumption and manually feed materials at all times, thereby reducing labor costs. Moreover, since the switching speed of the loading area and the placement plate 8 in the feeding area of ​​the automatic feeding device is faster than that of manual feeding, the automatic feeding device also improves the overall working efficiency of the die-cutting machine.

[0048] Example 2, reference Figures 13 and 14 , when the production space is not enough to install the conveyor belt.

[0049] At this time, the loading method of the feeding area is that the operator uses a forklift to place the stacked materials on the storage plate 8 of the feeding area, and the automatic alignment device is cancelled. The rest of the machine operation method is the same as that of Example 1.

[0050] Existing die-cutting machines operate by waiting for material consumption to complete, then stopping the machine and manually refilling. This requires operators to constantly monitor material consumption. Otherwise, if the operator fails to refill material after material consumption, the production efficiency of the die-cutting machine will be affected. The present invention can reduce labor usage in the material die-cutting process by 50%-70%. Compared to existing die-cutting machines, a single operator can simultaneously manage three times the number of die-cutting machines of the present invention while maintaining machine efficiency, reducing labor costs while maintaining production efficiency.
