Technical Field

[0001] This utility model relates to the field of die-cutting machine technology, and in particular to a multifunctional constant force embossing device and a die-cutting machine. Background Technology

[0002] The die-cutting machine is the core equipment for paper roll processing. It consists of a stamping device, precision mold, feeding mechanism and intelligent control system. It is widely used in the production of food packaging such as yogurt caps and beverage caps. It achieves cap forming through precise die-cutting of paper roll material by mold.

[0003] However, in the embossing process of die-cutting machines, existing die-cutting machines can only complete one embossing per pass, resulting in low production efficiency. The lack of a precise positioning device during embossing leads to disordered pattern positions on the embossed products, affecting the yield rate. Especially in mass production, the cumulative error from multiple embossings can easily cause pattern deviation, and manual adjustment is time-consuming and labor-intensive, failing to meet the demands for high-precision and high-efficiency processing. Therefore, a multi-functional constant-force embossing device and die-cutting machine are needed. Utility Model Content

[0020] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] Specific embodiments, combined with Figures 1 to 20 The technical solution of this utility model is further illustrated as shown.

[0022] A multifunctional constant-force embossing device generally includes a first processing mechanism 41 for embossing one type of mark and a second processing mechanism 42 for embossing another type of mark. An adjustment mechanism 43 is provided between the first processing mechanism 41 and the second processing mechanism 42 for adjusting the material after embossing by the first processing mechanism 41. The first processing mechanism 41 and the second processing mechanism 42 can provide various processing directions. Optionally, the first processing mechanism 41 processes a portion of the material, while the second processing mechanism 42 processes another portion of the material, allowing the material to produce various products when passing through the blanking device 2, thus improving the practicality of the equipment.

[0023] Specifically, the first processing mechanism 41 includes a first impression roller assembly 411 and a first drive mechanism 412 for driving the first impression roller assembly 411. The first impression roller assembly 411 includes a first impression roller 4111 driven by the first drive mechanism 412 and a first mating roller 4112 that cooperates with the first impression roller 4111 to imprint on the material. The first impression roller assembly 411 is capable of performing a type of embossing on the material.

[0024] The first impression roller assembly 411 further includes an adjusting handwheel 4113 for adjusting the impression depth. The adjusting handwheel 4113 can adjust the distance between the first impression roller 4111 and the first mating roller 4112 by rotating it. The adjusting handwheel 4113 can adjust the impression depth to ensure the stability of the impression and the type of impression.

[0025] Optionally, the first impression roller 4111 is driven to rotate by the first driving mechanism 412. The first processing mechanism 41 is provided with a first mounting groove 413 for movably mounting the first mating roller 4112. The adjusting handwheel 4113 can adjust the first mating roller 4112 to move up and down within the first mounting groove 413, thereby adjusting the distance between the first impression roller 4111 and the first mating roller 4112. The adjusting handwheel 4113 can drive the first mating roller 4112 to move up and down within the first mounting groove 413, thereby adjusting the distance between the first impression roller 4111 and the first mating roller 4112, that is, adjusting the depth of the impression.

[0026] Specifically, the adjustment mechanism 43 includes a detection roller group 431 for detecting the state of the material after being processed by the first processing mechanism 41, a positioning roller group 432 for adjusting the material, and a third drive mechanism 433 for driving the positioning roller group 432. The detection roller group 431 includes a first roller 4311 for transferring material, disposed between the detection roller group 431 and the first processing mechanism 41, and a detection element 4312 for detecting the degree of material offset, disposed on one side of the first roller 4311. The first roller 4311 first receives the material processed by the first processing mechanism 41. The detection element 4312 detects the degree of material offset and transmits the signal to the positioning roller group 432. The positioning roller group 432 positions and corrects the material, ensuring that it can be stably processed by the second impression roller group 421 and subsequently punched by the punching device 2.

[0027] The positioning roller group 432 includes a first positioning roller 4321 driven by the third driving mechanism 433, and a first adjusting roller 4322 whose position can be adjusted according to the detection status of the detection element 4312. The first adjusting roller 4322 can adjust its position to ensure that the material is accurately processed when it enters the second processing mechanism 42.

[0028] Optionally, the adjustment mechanism 43 further includes a third mounting groove 434 for movably mounting the first adjusting roller 4322 and a second driving member 435 cooperating with the detection member 4312. The second driving member 435, upon receiving a signal from the detection member 4312, adjusts the first adjusting roller 4322 to move up and down within the third mounting groove 434, thereby adjusting the distance between the first positioning roller 4321 and the first adjusting roller 4322. The second driving member 435 can drive the first adjusting roller 4322 to move up and down within the third mounting groove 434 according to the signal fed back by the detection member 4312, thereby adjusting the distance between the first positioning roller 4321 and the first adjusting roller 4322, thus adjusting the position of the material and facilitating the processing of the material by the second processing mechanism 42.

[0029] Specifically, the second processing mechanism 42 includes a second impression roller group 421 and a second drive mechanism 422 for driving the second impression roller group 421. The second impression roller group 421 includes a second impression roller 4211 driven by the second drive mechanism 422 and a second mating roller 4212 that cooperates with the second impression roller 4211 to imprint on the material. The second impression roller group 421 can imprint another type of embossing on the material. Optionally, the embossing of the first impression roller group 411 and the second impression roller group 421 is different. By adjusting the position of the embossing and the relationship between their corresponding drive mechanisms, different embossings can be imprinted on the material, improving the practical performance of the die-cutting machine.

[0030] Optionally, the second processing mechanism 42 further includes a second mounting groove 423 for movably mounting the second mating roller 4212 and a first driving member 424 for driving the second mating roller 4212 to move up and down along the second mounting groove 423. The first driving member 424 can drive the second mating roller 4212 to move up and down along the second mounting groove 423 to adjust the distance between the second impression roller 4211 and the second mating roller 4212. The first driving member 424 can drive the second mating roller 4212 to move up and down within the second mounting groove 423, thereby adjusting the distance between the second impression roller 4211 and the second mating roller 4212, i.e., adjusting the depth of the impression. Optionally, the second processing mechanism 42 further includes a detection device disposed on one side of the second impression roller group 421 for detecting the material's position. The detection device is electrically connected to the first driving member 424 to cooperate with the first driving member 424 in adjusting the position of the second mating roller 4212.

[0031] A punching machine generally includes a feeding device 1 for feeding materials and a punching device 2 disposed on one side of the feeding device 1. The punching device 2 has a first collecting device 31 for collecting punched products and a second collecting device 32 for collecting punched residue on one side. During operation, materials are stored in the feeding device 1 and used to supply materials for punching by the punching device 2. After the punching device 2 completes the punching, the punched products are stored in the first collecting device 31, and the remaining material (i.e., the portion of the material remaining after punching) is stored in the second collecting device 32.

[0032] Based on the overall design concept described above, a multi-functional constant-force stamping device, as described above, is provided between the feeding device 1 and the blanking device 2. Optionally, the multi-functional constant-force stamping device includes a first processing mechanism 41 located near the feeding device 1 and a second processing mechanism 42 located near the blanking device 2. An adjustment mechanism 43 for adjusting the material is provided between the first processing mechanism 41 and the second processing mechanism 42. The multi-functional constant-force stamping device can pre-process the blanked product and facilitate material adjustment for subsequent material processing. The first processing mechanism 41 and the second processing mechanism 42 can provide various processing directions. Optionally, the first processing mechanism 41 processes a portion of the material, and the second processing mechanism 42 processes another portion of the material, so that multiple products can be obtained when the material passes through the blanking device 2, improving the practical performance of the equipment.

[0033] Based on the above overall design concept, the blanking device 2 includes a blanking fixed plate 21 and a blanking movable plate 22 that cooperates with the blanking fixed plate 21 to complete the blanking. The blanking movable plate 22 is provided with multiple movable guide posts 221, and the blanking fixed plate 21 is provided with multiple mating holes 211 corresponding to the movable guide posts 221. The blanking device 2 also includes a blanking drive mechanism 23 for driving the blanking movable plate 22 to move along the direction of the movable guide posts 221 and cooperate with the blanking fixed plate 21 to complete the blanking. The blanking drive mechanism 23 can drive the blanking movable plate 22 to move along the direction of the movable guide posts 221 and cooperate with the blanking fixed plate 21 to complete the blanking.

[0034] Specifically, the die-cutting fixed plate 21 is provided with a plurality of die-cutting holes 212, and the die-cutting movable plate 22 is provided with a plurality of die-cutting blades 222 corresponding to the die-cutting holes 212. The first collecting device 31 includes a receiving mechanism 311 corresponding to the die-cutting holes 212, and a stabilizing mechanism 312 that stabilizes the product in the die-cutting holes 212 after die-cutting. When the material is transferred between the die-cutting fixed plate 21 and the die-cutting movable plate 22, the die-cutting blades 222 cooperate with the die-cutting holes 212 on the die-cutting fixed plate 21 under the action of the die-cutting movable plate 22, and die-cut the product. The die-cut product is retained in the die-cutting holes 212. During subsequent die-cutting operations, the product gradually accumulates and is collected by the receiving mechanism 311 of the first collecting device 31. In addition, the stabilizing mechanism 312 ensures that the die-cut product maintains its shape and avoids interfering with the action of the die-cutting movable plate 22 and the die-cutting blades 222 during subsequent die-cutting, thus affecting the quality of the product and the continuous die-cutting operation.

[0035] Preferably, the blanking fixed plate 21 has two rows of blanking holes 212, and the blanking movable plate 22 has multiple blanking blades 222 corresponding to the blanking holes 212. The first processing mechanism 41 performs stamping on a portion of the material, and the second processing mechanism 42 performs stamping on another portion of the material. The stamping areas correspond to the positions of the blanking holes 212. One row of blanking holes 212 and its corresponding blanking blades 222 is responsible for blanking out one type of product processed by the first processing mechanism 41, while the other row of blanking holes 212 and its corresponding blanking blades 222 is responsible for blanking out one type of product processed by the second processing mechanism 42, thus enabling the blanking of multiple products using a single set of equipment.

[0036] Optionally, the receiving mechanism 311 includes multiple receiving columns 3111 for forming product channels and a limiting plate 3112 movably mounted on one of the receiving columns 3111, whose position can be adjusted as products accumulate. The limiting plate 3112 can move on the receiving column 3111, so that when more and more punched products are produced, the limiting plate 3112 keeps the products arranged in an orderly manner, facilitating subsequent orderly collection, metering, and packaging of the products.

[0037] The blanking fixing plate 21 is provided with a channel between the blanking hole 212 and the receiving mechanism 311, so that the blanked material can be buffered through the channel and then collected and packaged on the receiving column 3111 of the receiving mechanism.

[0038] Optionally, the material stabilizing mechanism 312 is a vacuum suction device capable of suctioning a vacuum. Multiple vacuum suction holes 2121 are provided on the inner circumference of the punching hole 212, and a flow channel is provided inside the punching fixing plate 21 for connecting the vacuum suction holes 2121 and the material stabilizing mechanism 312. By providing multiple vacuum suction holes 2121 on the inner circumference of the punching hole 212, the punched product is suctioned to maintain its shape, preventing interference with the movement of the punching movable plate 22 and the punching blade 222 during subsequent punching.

[0039] Around the punching device 2, the side of the punching device 2 closest to the second collecting device 32 is provided with a first feeding roller group 51 for conveying material and a fourth driving mechanism 52 for driving the first feeding roller group 51. The side of the punching device 2 away from the second collecting device 32 is provided with a second feeding roller group 61 for conveying material and a fifth driving mechanism 62 for driving the second feeding roller group 61. The punching device 2 is located between the first feeding roller group 51 and the second feeding roller group 61, so that the material is conveyed to the punching device 2 by the second feeding roller group 61 under the drive of the second collecting device 32 to complete the punching, and then guided by the first feeding roller group 51 and collected by the second collecting device 32.

[0040] Specifically, the second collecting device 32 includes a receiving roller 321 for receiving material and a collecting drive mechanism 322 located on one side of the receiving roller 321 for driving its operation. The fourth drive mechanism 52 and the fifth drive mechanism 62 cycle-start and stop to achieve a stop at the working position of the punching device 2 when the material is being moved, and to remove the punched residue from the working position of the punching device 2 after punching is completed. This brief stop facilitates the punching device 2 in completing the punching of the material, while ensuring that the punched residue is collected by the second collecting device 32.

[0041] In addition, the blanking drive mechanism 23 is a servo motor capable of cyclically starting and stopping to intermittently drive the blanking movable plate 22 to blank products. The blanking fixed plate 21 is equipped with a measuring mechanism 213 that leaves a mark on the products after a certain number of blanked products have been collected. The measuring mechanism 213 is electrically connected to the blanking drive mechanism 23. In short, the measuring mechanism 213 is a servo cylinder that leaves a mark on the material after the blanking drive mechanism 23 has blanked a certain number of products. The action of the measuring mechanism 213 is affected by the number of times the blanking drive mechanism 23 operates. After the blanking drive mechanism 23 operates a certain number of times, the measuring mechanism 213 receives a signal and operates, leaving a mark on the material to be blanked, facilitating subsequent measurement and collection.

[0042] More specifically, the metering mechanism 213 is located between the punching hole 212 and the second feeding roller group 61, so that after a certain number of products are punched, the metering mechanism 213 will leave a mark on the part of the material to be punched, and then the punched part with the mark will enter the punching hole 212 to complete the punching and enter the first collecting device 31.

[0043] Preferably, the measuring mechanism 213 is a servo cylinder that actuates to leave a mark on the material after the blanking drive mechanism 23 drives the blanking movable plate 22 to blank a certain quantity. After the blanking drive mechanism 23 drives the blanking movable plate 22 to blank a certain quantity, the measuring mechanism 213 receives a signal and drives the piston end of the cylinder to leave a mark on the material to be blanked. This part, after being blanked, enters the receiving mechanism 311 and serves as a standard for counting the number of products to facilitate the product packaging process.

[0044] Based on the overall design concept described above, a material accumulation device 7 is provided between the blanking device 2 and the multifunctional constant force stamping device for storing material and maintaining material tension. The second collecting device 32, the blanking device 2, the first collecting device 31, the material accumulation device 7, the multifunctional constant force stamping device, and the feeding device 1 are arranged sequentially. The material accumulation device 7 can cooperate with the blanking device 2 to complete the blanking. Since the blanking device 2 pauses briefly during blanking, the material accumulation device 7 can accumulate material while maintaining material tension to facilitate the blanking of the blanking device 2, while maintaining the feeding progress of the feeding device 1 and ensuring the stable operation of the entire blanking machine.

[0045] Specifically, the material accumulation device 7 includes a material accumulation mounting mechanism 71, a servo drive mechanism 72 disposed within the material accumulation mounting mechanism 71, and a constant tension roller group 73 driven by the servo drive mechanism 72 to adjust the material tension. The constant tension roller group 73 can accumulate material and maintain the tension of that portion of the material, facilitating the punching device 2 to complete the punching.

[0046] The material accumulation installation mechanism 71 includes two parallel baffles 711. Each side of the two baffles 711 is provided with a first guide post 712 for supporting and installing the constant tension roller group 73 and a second guide post 713 that is spaced parallel to the first guide post 712. The servo drive mechanism 72 includes two pairs of spaced-apart pulleys 721, a transmission belt 722 that cooperates with the pulleys 721, and a servo drive component 723 for driving the pulleys 721. The servo drive mechanism 72 is fixed on the material accumulation mounting mechanism 71, and the first guide post 712 and the second guide post 713 provide convenience for the installation and tension adjustment of the constant tension roller group 73.

[0047] Specifically, the constant tension roller assembly 73 includes two constant force rollers 731 respectively disposed on two pairs of first guide posts 712 and second guide posts 713, and a constant force mounting member 732 for mounting the constant force rollers 731. One of the constant force rollers 731 is mounted on the first guide post 712, and the other constant force roller 731 is mounted on the second guide post 713, ensuring that the two constant force rollers 731 are on two horizontal planes and have a certain distance between them, which facilitates material accumulation and constant tension treatment of the material.

[0048] Optionally, the constant force mounting member 732 of one of the constant force rollers 731 is movably connected to the first guide post 712, and the constant force mounting member 732 of the other constant force roller 731 is fixedly connected to the second guide post 713. One side of the constant force mounting member 732 of one of the constant force rollers 731 is provided with an engaging member 74 that cooperates with the transmission belt 722. The constant force roller 731 on the side of the constant force mounting member 732 with the engaging member 74 can move under the drive of the servo drive mechanism 72 to adjust the distance between the two constant force rollers 731.

[0049] Specifically, the servo drive 723 is a servo motor with built-in soft limiters that can precisely control speed, position and torque.

[0050] Based on the overall design concept described above, a straightening device 8 for automatically straightening the paper roll is provided between the material accumulation device 7 and the multifunctional constant force printing device. As the material at the feeding device 1 is collected by the second collecting device 32, the diameter of the material roll gradually decreases. The straightening device 8 can adjust according to the change in the material paper roll at the feeding device 1 to straighten the paper roll, thus providing a stable material input for the subsequent operation of the die-cutting device 2.

[0051] Specifically, the straightening device 8 includes a straightening roller 81 and a straightening drive member 82 for driving the straightening roller 81. A floating straightening member 83, capable of rotating around the straightening roller 81, is provided on one side of the straightening roller 81. Material rotates around the straightening roller 81 and the floating straightening member 83. The straightening roller 81 remains stationary, its driving speed controlled by the straightening drive member 82. Simultaneously, the floating straightening member 83 can rotate around the axis of the straightening roller 81, adaptively adjusting its rotation angle to avoid the influence of material transferred to the punching device 2 during material consumption.

[0052] More specifically, the straightening roller 81 includes a roller body 811 and a straightening mounting member 812 connected to the straightening drive member 82 for mounting the roller body 811. The floating straightening member 83 includes two spaced-apart floating rollers 831 with lengths corresponding to the roller body 811, and a movable member 832 movably connected to the straightening mounting member 812. Material is conveyed to subsequent devices around the straightening roller 81 via the two floating rollers 831. The floating straightening member 83 can rotate around the straightening mounting member 812 with the axis of rotation of the roller body 811 as its rotation axis, thereby achieving adaptive adjustment of the rotation angle.

[0053] More specifically, the movable component 832 includes a mounting portion 8321 for mounting the two floating rollers 831 and a mounting arm 8322 connected to the mounting portion 8321 for movably connecting with the straightening mounting component 812.

[0054] Specifically, the straightening drive 82 is a servo drive motor capable of precisely controlling speed, position, and torque.

[0055] In addition, a geared motor 821 is provided on one side of the straightening drive component 82. The geared motor 821 can work with the straightening drive component 82 to provide stable torque and precise speed control, ensuring the material feeding process.

[0056] The working principle of this embodiment is as follows: This utility model proposes a multifunctional constant-force embossing device and a die-cutting machine. The multifunctional constant-force embossing device, by setting a measuring mechanism 213 on the die-cutting fixing plate 21, leaves an imprint on the products after a certain number of die-cut products are collected, facilitating accurate subsequent product packaging. Its specific working principle is as follows: Overall, the feeding device 1 is responsible for feeding the paper rolls of material. The multi-functional constant force printing device completes the diverse processing of the material. After processing, the material is straightened by the straightening device 8 to avoid the material being transmitted to the punching device 2 during the material consumption process. Then the material is conveyed to the accumulating device 7, which accumulates the material while maintaining the material tension to facilitate the punching of the punching device 2, and at the same time maintains the feeding progress of the feeding device 1. After the punching device 2 completes the punching of the material, the first collecting device 31 collects the punched products, and the second collecting device 32 collects the remaining material after punching.

[0057] The first processing mechanism 41 performs printing on a portion of the material, and the second processing mechanism 42 performs printing on another portion of the material. The two printing areas correspond to the cutting area of ​​the die-cutting device 2. An adjustment mechanism 43 is provided between the first processing mechanism 41 and the second processing mechanism 42 to adjust the paper after printing by the first processing mechanism 41, which facilitates the positioning of the printing by the second processing mechanism 42. This allows the paper roll to be printed with multiple patterns to achieve product diversity, enabling multiple patterns to be printed on one machine and improving the practical performance of the die-cutting machine.
