Description

Technical Field

[0001] The invention relates to the technical field of automatic die-cutting, and in particular to a die-cutting machine for jigsaw puzzle processing. Background Art

[0002] In the process of jigsaw puzzle processing, the die-cutting machine is one of the important equipment to achieve efficient processing. Especially in the process of jigsaw puzzle cutting, in order to ensure the accuracy of the puzzle shape and the cutting quality, the die-cutting machine usually needs to accurately support the puzzle. There are two common support methods: flexible support and rigid support, but each method has its limitations in practical applications, especially in the process of long-term use, the stability of the support height and the support effect is particularly prominent.

[0003] At present, traditional flexible support materials (such as rubber, elastic plastic, etc.) are widely used in jigsaw processing. Their advantages are that they can provide adaptive support according to the shape of the object being processed, and they have a certain elasticity, which can reduce damage caused by excessive pressure or unbalanced torque. However, a significant disadvantage of flexible support materials is that the elasticity of the material is easily fatigued during long-term use, and the support height will gradually shrink, resulting in insufficient support force and inability to maintain the preset support height. This defect makes it impossible for the flexible support to maintain sufficient stability under continuous production and long-term high load conditions, thereby affecting the processing accuracy and cutting effect. On the other hand, rigid support materials (such as metal support plates, rigid rubber, etc.) can maintain a high support force during long-term support due to their strong rigidity and stability, and effectively avoid the problem of height shrinkage of flexible support materials. However, rigid support also has more serious defects in the processing process, especially in the cutting process, the support material with higher hardness may cause damage to the tool, increase tool wear and reduce service life. At the same time, rigid support is difficult to adapt to the shape changes of the jigsaw puzzle, and cannot provide precise support like flexible support. Therefore, in jigsaw puzzle processing with high precision requirements, the application scope of rigid support materials is limited.

[0004] For example, a Chinese patent with the authorization announcement number CN214561520U discloses a die-cutting device for jigsaw puzzles, which uses a rigid support. The device achieves the die-cutting effect of the jigsaw puzzle by placing the jigsaw puzzle on a push plate and driving the cutter with a hydraulic cylinder to complete the cutting. However, since the cutter is in direct contact with the upper surface of the push plate during the die-cutting process and lacks effective buffer protection, the cutter is prone to significant wear during long-term use, resulting in a significant reduction in the service life of the cutter. In addition, cutter wear will reduce cutting accuracy, affect die-cutting quality, and increase equipment maintenance and replacement costs, severely limiting the efficiency and stability of die-cutting operations. Summary of the invention

[0005] In view of the above problems, a die-cutting machine for puzzle processing is provided, and a device is proposed which can not only provide continuous and stable flexible support and constant support height when die-cutting puzzles, but also effectively avoid tool wear; thereby solving the technical problems that when existing die-cutting equipment uses rigid support, tool wear is easily caused by direct contact between the tool and the support surface; when using flexible support, the flexible support is easy to deform, resulting in insufficient support height and weak support effect.

DETAILED DESCRIPTION

[0030] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] See also Figures 1 to 10 As shown: A die-cutting machine for jigsaw puzzle processing, comprising: a die-cutting machine 1, the die-cutting machine 1 is provided with a cutting knife 11 for die-cutting jigsaw puzzles; a stroke adjustment module 2, the stroke adjustment module 2 is horizontally fixedly arranged outside the cutting knife 11 and the adjustment end is vertically arranged downward; a transfer module 3, the transfer module 3 is horizontally fixedly arranged on the die-cutting machine 1, and the transfer module 3 is provided with a transfer platform 31 that can slide between a cutting station and a loading station; a supporting module 4, the supporting module 4 is horizontally fixedly arranged on the transfer platform 31, and the supporting module 4 is used to support the jigsaw puzzle to be cut; the supporting module 4 is provided with a supporting platform 41 for supporting the jigsaw puzzle and a supporting unit 5 for driving the supporting platform 41 to switch between a rigid support state and a flexible support state.

[0032] When the jigsaw puzzle needs to be cut, the staff first slides the transfer platform 31 from the cutting station, i.e., the near end of the transfer module 3 and below the cutting knife 11, to the loading station, i.e., the far end of the transfer module 3; then the jigsaw puzzle to be cut is placed on the supporting platform 41, and the transfer platform 31 is pushed back to the cutting station. At this time, the die-cutting machine 1 is started, and the cutting knife 11 moves longitudinally under the drive of the die-cutting machine 1 and applies downward pressure toward the jigsaw puzzle through the cutting knife 11, thereby realizing the cutting operation of the jigsaw puzzle through the cutting knife 11.

[0033] During the cutting process, the support module 4 is set in a flexible support state. When the jigsaw puzzle is cut by the cutting knife 11, the downward pressure of the cutting knife 11 is applied to the support platform 41 through the stroke adjustment module 2. When the support platform 41 is subjected to downward pressure, the support platform 41 cooperates with the support unit 5 to autonomously shrink longitudinally, thereby avoiding the rigid contact between the cutting knife 11 and the support platform 41. This effectively reduces the wear problem of the cutter head caused by the cutting knife 11 hitting the support platform 41, thereby ensuring the working life and cutting accuracy of the cutting knife 11.

[0034] The adjustable flexible support characteristics of the support module 4 solve the technical problem that the cutting knife 11 of the traditional jigsaw puzzle die-cutting equipment is prone to contact with the support platform and cause wear when the cutting thickness exceeds the limit; at the same time, stable support for the jigsaw puzzle is achieved during the cutting process, thereby improving the cutting efficiency and product processing quality.

[0035] See also Figure 3 , Figure 6 and Fig. 9 As shown: the support unit 5 includes a guiding element 51 for guiding the movement of the supporting platform 41 in the longitudinal direction and a supporting element 52 for flexibly supporting the supporting platform 41; the guiding element 51 is provided with a lifting plate 511 for longitudinal movement; the guiding element 51 is fixedly arranged on the transfer platform 31 in a horizontal state; the supporting platform 41 is fixedly arranged on the lifting plate 511 in a horizontal state; the supporting element 52 is fixedly arranged in the guiding element 51 in a horizontal state and the supporting end is fixedly connected to the lifting plate 511.

[0036] When the jigsaw puzzle needs to be carried, the jigsaw puzzle is first placed on the carrying platform 41, and the supporting element 52 is driven to move. The supporting end of the supporting element 52 applies a supporting force to the lifting plate 511, so that the lifting plate 511 gradually rises until the lifting plate 511 reaches a preset carrying height and stops, and stabilizes at the current height, thereby achieving the effect of fixing the jigsaw puzzle at a preset height, ensuring that the jigsaw puzzle is in the position to be cut.

[0037] During the process of cutting the jigsaw placed on the supporting platform 41 by the cutting knife 11, if the downward pressure on the lifting plate 511 is greater than the pressure required for jigsaw cutting, it means that the pressure applied by the cutting knife 11 directly acts on the supporting platform 41. At this time, the supporting height of the supporting element 52 will automatically shrink, driving the lifting plate 511 and the supporting platform 41 thereon to move downward synchronously. This ensures that the supporting platform 41 will not have rigid contact with the cutting knife 11 during the cutting process, thereby effectively avoiding problems such as wear of the cutting knife 11, damage to the cutting edge, or reduced cutting accuracy caused by rigid contact.

[0038] Through the adaptive height adjustment of the top support element 52, flexible support for the lifting plate 511 and the jigsaw puzzle is achieved, which can not only avoid wear of the cutting knife 11 when the cutting knife 11 cuts the jigsaw puzzle, but also ensure that the jigsaw puzzle is firmly supported to the optimal cutting height, thereby significantly improving the cutting accuracy and service life of the equipment.

[0039] See also Figure 6 and Fig. 9 As shown: the guiding element 51 also includes a fixed bottom plate 512, a sleeve column 513 and a guide rod 514; the fixed bottom plate 512 is horizontally fixedly arranged on the transfer platform 31; four sleeve columns 513 are arranged, and the four sleeve columns 513 are arranged vertically on the upper surface of the fixed bottom plate 512 in a rectangular array and are respectively arranged close to the four corners of the fixed bottom plate 512; four guide rods 514 are arranged, and the four guide rods 514 are arranged vertically on the lower surface of the lifting plate 511 and are arranged one by one with the four sleeve columns 513 and slidably cooperate with the sleeve columns 513.

[0040] The lifting plate 511 slides with four sleeves 513 through four guide rods 514 vertically arranged at the bottom, ensuring that the lifting plate 511 only has the freedom of longitudinal sliding during use, thereby effectively limiting the lateral displacement and ensuring the smooth and accurate operation of the lifting plate 511. When the supporting platform 41 is subjected to the downward pressure of the cutting knife 11, the pressure is transmitted to the lifting plate 511 through the supporting platform 41, and then transmitted to the supporting element 52 through the lifting plate 511. At this time, the supporting end of the supporting element 52 will automatically shrink because the external pressure exceeds the cutting pressure of its supporting force on the jigsaw puzzle, and stop supporting the lifting plate 511. At the same time, after losing the supporting force, the lifting plate 511, under its own weight and the guiding action of the sleeve 513, axially approaches the fixed bottom plate 512 along the guide rod 514, thereby realizing the longitudinal downward movement of the supporting platform 41.

[0041] Through the matching structure of the sleeve column 513 and the guide rod 514, the movement trajectory of the lifting plate 511 is ensured to be precisely controllable and lateral deviation is avoided. At the same time, under the action of downward pressure, the automatic retraction function of the top support element 52 can effectively prevent the direct rigid contact between the cutting knife 11 and the supporting platform 41, reduce the risk of wear of the cutting knife 11, and extend the service life of the equipment. Through the matching of the sleeve column 513 and the guide rod 514, the movement stability of the lifting plate 511 is improved; the automatic retraction function of the top support element 52 is used to prevent the rigid contact between the cutting knife 11 and the supporting platform 41, significantly reducing the probability of wear of the cutting knife 11; the dynamic adjustment of the lifting plate 511 during the cutting process is realized, which not only ensures the flexible support effect, but also meets the cutting accuracy and long-term stability requirements of the equipment.

[0042] See also Figure 4 and Fig. 9As shown, a cushioning rubber pad 42 is attached to the supporting platform 41 , and circular through holes 43 are respectively formed at the four corners of the cushioning rubber pad 42 .

[0043] The thickness of the buffer rubber pad 42 is 1-3 mm.

[0044] The cushioning rubber pad 42 is used to place the puzzle, and uses its friction to ensure that the puzzle placed on the cushioning rubber pad 42 will not move autonomously. The puzzle can be firmly maintained in the cutting position during the cutting process to prevent displacement due to external force. When the puzzle is cut by the cutting knife 11, after the cutting is completed, the cutting knife 11 will make short-range contact with the cushioning rubber pad 42 after cutting through the puzzle. At this time, the cushioning rubber pad 42 will only produce slight deformation, but will not cause damage. Thereby, the puzzle is completely cut, and the problem of blade wear that may be caused by the contact between the cutting knife 11 and the hard surface is avoided. The thickness of the cushioning rubber pad 42 is set to 1-2 cm. This range allows it to provide flexible contact to protect the blade of the cutting knife 11 from damage, and to avoid the problem of collapse under long-term support.

[0045] By using the cushion rubber pad 42 to provide flexible support, the cutting knife 11 is prevented from directly contacting the hard surface, thereby reducing the risk of blade wear. The reasonable thickness of the cushion rubber pad 42 ensures that it will not collapse during long-term use, and can effectively protect the cutting knife 11 and extend the service life of the cutting knife 11.

[0046] See also Fig. 9 As shown: the upper surface of the supporting platform 41 is also provided with a slot 44 and a correction block 45 detachably arranged in the slot 44; the slot 44 is a cross-shaped structure and is arranged in multiple groups; four correction blocks 45 are arranged, and the four correction blocks 45 are respectively arranged at the edges of the supporting platform 41, and the four correction blocks 45 form a limit interval for limiting the puzzle.

[0047] The supporting platform 41 may also be detachably provided with a filling block 46 embedded in the slot 44 , and the filling block 46 is used to fill the slot 44 when not in use, so that the upper surface of the supporting platform 41 always maintains a flat supporting plane.

[0048] The size, length and width of the limit interval can be self-adjusted according to the size of the puzzle to ensure that the puzzle remains fixed during the cutting process to avoid autonomous deviation or sliding; the thickness of the correction block 45 is less than that of the cutting knife 11.

[0049] See also Figure 8 As shown, the stroke adjustment module 2 includes an adjustment rod 21 that can move closer to or farther away from the transfer platform 31 along the longitudinal direction; and the length of the adjustment rod 21 is greater than the thickness of the cutting knife 11.

[0050] The adjustment stroke of the adjustment rod 21 is the sum of the thickness of the cutting knife 11 plus the thickness of the buffer rubber pad 42. In order to ensure that the jigsaw puzzle can be completely cut by the cutting knife 11 and can pass through the jigsaw puzzle in a short distance to contact the buffer rubber pad 42, it is only necessary to reduce the total adjustment stroke of the adjustment rod 21 by 0.5 cm; when the jigsaw puzzle is cut by the cutting knife 11, the front end of the adjustment rod 21 will pass through the circular through hole 43 and contact the supporting platform 41, and the downward pressure will be transmitted to the supporting platform 41 through the adjustment rod 21, thereby prompting the support unit 5 to shrink; since the adjustment stroke of the adjustment rod 21 is the sum of the thickness of the cutting knife 11 plus the thickness of the buffer rubber pad 42 and is reduced by 0.5 cm; when the adjustment rod 21 contacts the supporting platform 41, the cutting knife 11 can only pass through the jigsaw puzzle and continue to move forward 0.5 cm to contact the buffer rubber pad 42, so that the jigsaw puzzle can be completely cut without damaging the cutting knife 11.

[0051] See also Figure 4 and Figure 8 As shown: the stroke adjustment module 2 also includes a fixing frame 22, an adjusting sleeve 23 and a locking member 24; the fixing frame 22 is horizontally fixedly arranged at the die-cutting end of the die-cutting machine 1 and is arranged outside the cutting knife 11, and the lower surface of the fixing frame 22 is arranged flush with the root of the cutting knife 11; four adjusting sleeves 23 are arranged, and the four adjusting sleeves 23 are vertically arranged on the upper surface of the fixing frame 22 and are respectively arranged near the four corners of the fixing frame 22; four adjusting rods 21 are arranged, and the four adjusting rods 21 are respectively screwed in the four adjusting sleeves 23, and the side walls of the four adjusting sleeves 23 are also respectively screwed with locking members 24 that can lock the adjusting rods 21 in the adjusting sleeves 23.

[0052] When it is necessary to adjust the adjustment stroke of the adjustment rod 21, the staff first loosens the locking piece 24 to unlock the adjustment rod 21 to ensure that the adjustment rod 21 can rotate freely during the adjustment process; then, the staff adjusts the stroke according to the required adjustment stroke by rotating the adjustment rod 21 until the adjustment rod 21 reaches the preset target stroke; after the adjustment is completed, the staff stops rotating the adjustment rod 21 and firmly locks the adjustment rod 21 in the adjustment sleeve 23 by screwing the locking piece 24, thereby ensuring that the adjustment rod 21 maintains a stable adjustment position during use without loosening or offsetting.

[0053] See also Figure 2 , Figure 3 and Figure 6As shown: the supporting element 52 includes an airbag 53, a medium exporting component 54 and a medium pressure maintaining component 55; the airbag 53 is fixedly arranged in the guiding element 51; the medium exporting component 54 is fixedly arranged at the exporting port of the airbag 53, and the medium exporting component 54 is used to automatically export the medium when the airbag 53 exceeds the preset pressure; the medium pressure maintaining component 55 is fixedly arranged at the importing port of the airbag 53, and the medium pressure maintaining component 55 is used to automatically import the medium when the airbag 53 is lower than the preset pressure.

[0054] The transmission medium is specifically a liquid, such as water or hydraulic oil.

[0055] When the jigsaw puzzle needs to be cut, the airbag 53 starts to expand continuously under the drive of the medium pressure-maintaining component 55 until it expands to a preset pressure value. At this time, the airbag 53 pushes the lifting plate 511 to a preset height through the jacking effect, so that the jigsaw puzzle is in the correct cutting position. After the cutting knife 11 completes the cutting of the jigsaw puzzle, the downward pressure applied by the cutting knife 11 is transmitted to the supporting platform 41 through the stroke adjustment module 2, and further transmitted to the lifting plate 511. In this process, when the airbag 53 is subjected to pressure, the medium filled therein will be released through the outlet of the medium pressure-maintaining component 55, thereby forcing the lifting plate 511 to slowly descend, so that even if the cutting knife 11 moves beyond the stroke, it will not affect the equipment, the jigsaw puzzle and the supporting platform 41, and has an adaptive buffering effect. At this time, the supporting platform 41 will also move away from the cutting knife 11 synchronously, thereby protecting the cutting edge of the cutting knife 11 and preventing the tool from being worn or damaged due to rigid contact or excessive pressure.

[0056] Through the adjustment of the airbag 53, combined with the coordination of the medium pressure-maintaining component 55 and the stroke adjustment module 2, accurate jigsaw cutting positioning and force unloading process are achieved. The airbag 53 can slowly release the downward pressure of the cutting knife 11 after cutting is completed, protecting the supporting platform 41 and effectively preventing the wear of the cutting knife 11.

[0057] See also Fig.10 As shown: the medium export component 54 includes an export tube 541, an export hole 542, an export nozzle 543, an opening and closing piston 544 and a return spring 545; the export nozzle 543 is coaxially fixedly arranged at the export outlet of the airbag 53, and the side wall of the export nozzle 543 is also provided with an export hole 542 that can export the internal medium; the export nozzle 543 is coaxially sleeved and installed outside the export nozzle 543 and is connected with the export hole 542; the opening and closing piston 544 is coaxially slidably arranged in the export nozzle 543; the return spring 545 is coaxially arranged in the export nozzle 543, and one end of the return spring 545 abuts against the opening and closing piston 544, and the other end of the return spring 545 abuts against the inner wall of the far end of the export nozzle 543.

[0058] The supporting pressure of the return spring 545 is smaller than the supporting pressure on the lifting plate 511 and the die-cutting pressure on the jigsaw puzzle.

[0059] In the non-working state, the outlet nozzle 543 is connected to the external transmission pipeline to ensure the normal flow of the medium. Under the action of the reset spring 545, the opening and closing piston 544 is always in a position away from the outlet hole 542. When the cutting knife 11 applies die-cutting pressure to the jigsaw puzzle and transmits it to the supporting platform 41 through the stroke adjustment module 2, the pressure acts on the lifting plate 511 synchronously, causing the lifting plate 511 to move downward and exert pressure on the airbag 53. In this process, after the airbag 53 is pressurized, the medium is pushed into the outlet tube 541, and the pressure inside the airbag 53 is used to drive the opening and closing piston 544 to move axially toward the far end of the outlet tube 541 until the reset spring 545 is further compressed, and the opening and closing piston 544 slides to the rear side of the outlet hole 542, allowing the medium to flow into the outlet nozzle 543 through the outlet hole 542. The airbag 53 is thereby contracted, which can achieve both rigid support before the downward pressure applied by the lifting plate 511 acts on the supporting platform 41, and flexible support conversion after the downward pressure acts on the supporting platform 41; when continuous rigid support is required, the outlet of the outlet nozzle 543 can be closed.

[0060] The airbag 53 and the opening and closing piston 544 cooperate to provide a switchable function of flexible and rigid support. By precisely controlling the flow of the medium and the movement of the opening and closing piston 544, the airbag 53 can be quickly switched according to the support strength required during the cutting process, thereby effectively avoiding damage caused by the contact between the cutting head and the hard surface and ensuring the support accuracy during the cutting process. This not only improves the working efficiency of the equipment, but also extends the service life of the cutting tool 11 and avoids the collapse problem during long-term support.

[0061] See also Figure 6 As shown, the medium pressure maintaining component 55 includes a medium input unit 551 and a pressure detection unit 552; the medium input unit 551 is fixedly arranged at the inlet of the airbag 53 through the detection unit.

[0062] The medium input unit 551 is specifically a pressure pump, which is used to continuously input the supporting medium into the airbag 53. The pressure detection unit 552 is a pressure detector, which is used to detect the pressure in the airbag 53 in real time, so as to ensure the consistency of the supporting height of the airbag 53 in real time. The medium input unit 551 and the pressure detection unit 552 are both existing technologies and are not described here. When each cutting action is completed, that is, when the transfer platform 31 is pulled to the loading station, the medium input unit 551 will cooperate with the pressure detection unit 552 to re-input the supporting medium into the airbag 53.

[0063] The present invention can not only automatically switch the supporting mode but also effectively protect the tool and reduce the wear of the tool.

[0064] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the protection of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
