Description

Technical Field

[0001] This application relates to the field of paper-aluminum-plastic processing equipment, and in particular to a paper-aluminum-plastic easy-folding roll forming device. Background Technology

[0002] The paper-aluminum-plastic easy-tear line roll forming device is a precision mechanical equipment specifically used to process easy-tear lines on paper-aluminum-plastic composite packaging. Its core function is to form controllable micro-structural damage at specific locations on the composite material through the roll forming process, so that the packaging can maintain overall airtightness and can be easily torn along a predetermined path during use, achieving a balance between "precise tearing" and "high barrier".

[0003] Existing easy-to-break line roll forming equipment mostly adopts a step-by-step roll forming process. The horizontal cutting and vertical dotted line creasing need to be processed by two sets of independent roller systems in sequence, which results in a lengthy process and limited efficiency. In addition, the material positioning of the two times is prone to cumulative errors, causing misalignment of horizontal and vertical creasing, which can easily lead to irregular breakage when tearing. Utility Model Content

[0004] To improve the problems of lengthy processes and limited efficiency caused by step-by-step roll forming, this application provides a paper-aluminum-plastic easy-fold roll forming apparatus.

[0005] The paper-aluminum-plastic easy-folding roll forming device provided in this application adopts the following technical solution:

[0006] A paper-aluminum-plastic easy-tear line roll forming device includes a machine frame, with working rollers rotatably connected through both sides of the machine frame. Die-cutting blocks are fixedly connected to the surface of the working rollers, and auxiliary components for adjusting the position of longitudinal easy-tear line indentations are provided inside the working rollers.

[0007] By adopting the above technical solution, the device integrates the die-cutting blade and auxiliary components into the same working roller, which reduces the floor space compared with the separate equipment. The built-in auxiliary components enable dynamic adjustment of the longitudinal tear line position, which can be adapted to different packaging specifications.

[0008] Preferably, the auxiliary component includes an arc groove that runs through and is linearly arrayed inside the work roller, and a die-cutting cutter with one side of its surface located on the surface of the work roller is movably connected inside the arc groove.

[0009] By adopting the above technical solution, the die-cutting roller is used to achieve the rolling of longitudinal easy-tear lines.

[0010] Preferably, the arc groove and the die-cutting roller are arranged in a circular array around the center of the working roller, and the die-cutting roller is connected end to end with its adjacent die-cutting roller.

[0011] By adopting the above technical solution, the die-cutting rollers distributed in a circular array are connected end to end, ensuring that the longitudinal dotted line indentation is uninterrupted.

[0012] Preferably, an inner layer cylinder is fixedly connected to the inner wall of the working roller, and a square groove is formed in the inner circumferential array of the inner layer cylinder and the working roller, penetrating the inner layer cylinder, the working roller, and the interior of the arc groove.

[0013] By adopting the above technical solution, the inner cylinder and the working roller form a composite structure, which improves the bending stiffness.

[0014] Preferably, the inside of the square groove is slidably connected to a connecting rod that is fixedly connected to one side of the die-cutting roller surface, and the inside of the working roller is slidably connected to a circular plate.

[0015] By adopting the above technical solution, the sliding fit between the square groove and the connecting rod eliminates radial clearance and ensures the displacement accuracy of the die-cutting roller.

[0016] Preferably, an arcuate groove is formed through one side of the surface of the circular plate, and a first cylinder that is fixedly connected to one side of the surface of the connecting rod is slidably connected inside the arcuate groove.

[0017] By adopting the above technical solution, the first cylinder slides inside the arc-shaped through groove to drive 44 to expand outward.

[0018] Preferably, a second cylinder is fixedly connected to the inner side of the circular plate and rotatably connected to one end of the working roller, and a handle is fixedly connected to the end of the second cylinder away from the working roller.

[0019] By adopting the above technical solution, the handle is used to facilitate the rotation of the second cylinder by the staff.

[0020] Preferably, a second limiting groove is provided on the surface of the second cylinder, a first limiting groove is provided on the side of the working roller near the handle, and a limiting slider is slidably connected inside the second limiting groove and slidably connected inside the first limiting groove.

[0021] By adopting the above technical solution, the limiting slider is simultaneously embedded in the first limiting groove and the second limiting groove, and the limiting slider needs to be lifted to rotate, thus avoiding accidental displacement during the production process.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By installing the die-cutting blade block and the die-cutting roller onto the working roller, the horizontal cutting die-cutting blade block and the vertical cutting die-cutting roller are integrated into the same upper roller. This allows for the simultaneous creasing of the horizontal and vertical easy-tear lines in one rolling operation, reducing processing time by at least half and avoiding misalignment of horizontal and vertical creasing caused by positioning errors due to two rolling operations.

[0024] 2. The longitudinal tear line opening position of the die-cutting roller can be changed by using the die-cutting blade block. It can be adjusted according to the size of the product. By rotating the second cylinder, the die-cutting roller expands out of the arc groove, thereby moving the die-cutting roller and the connecting rod to adjust the opening position of the longitudinal tear line. The position of the die-cutting roller is fixed by using the first limiting groove, the second limiting groove and the limiting slider to prevent the die-cutting roller from becoming unstable when the working roller is working.

[0034] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0035] This application discloses a paper-aluminum-plastic easy-folding roll forming device.

[0036] Reference Figure 1 , Figure 2A paper-aluminum-plastic easy-tear line roll forming device includes a machine frame 1, with both sides of the machine frame 1 rotatably connected to both ends of a working roller 2. One end of the surface of the working roller 2 is fixed to the fixed end of several die-cutting blocks 3. The die-cutting blocks 3 are used to create easy-tear lines by transverse indentation on the paper-aluminum-plastic composite material when the working roller 2 rotates. An auxiliary component 4 is provided inside the working roller 2 to adjust the position of the longitudinal easy-tear line indentation. The die-cutting blocks 3 and the auxiliary component 4 can simultaneously complete the transverse and longitudinal easy-tear line indentation in one roll forming. Support rollers 5 are rotatably connected to both sides of the machine frame 1 and are located below the working roller 2. One side of the machine frame 1 is fixedly connected to the mounting end of a drive motor 6. The output end of the drive motor 6 is fixedly connected to one end of the support roller 5 through a coupling. Gears 7 are fixedly connected to the ends of the working roller 2 and the support roller 5 away from the drive motor 6, and the two gears 7 are meshed together.

[0037] When in use, the operator starts the drive motor 6 through the controller. The drive motor 6 drives the support roller 5 to rotate. The rotation of the support roller 5 drives the working roller 2 to rotate through the gear 7. The rotation of the working roller 2 simultaneously drives the die-cutting blade block 3 and the die-cutting roller 44 to rotate on the surface of the support roller 5. The die-cutting blade block 3 and the die-cutting roller 44 work together with the support roller 5 to cut horizontal and vertical easy-tear lines on the paper-aluminum-plastic composite material.

[0038] Reference Figure 3 , Figure 4 The auxiliary component 4 includes five arcuate grooves 41 that are linearly arranged and penetrate the interior of the work roller 2. One of these grooves 41 is movably connected to a die-cutting cutter 44, with one end of the cutter 44 fitting against the surface of the work roller 2. The dimensions of the arcuate grooves 41 are adapted to the dimensions of the die-cutting cutter 44. The arcuate grooves 41 restrict the movement of the die-cutting cutter 44 during operation. The linearly arranged arcuate grooves 41 are distributed in three circumferential arrays around the center of the work roller 2. The cutting rollers 44 are also arranged in three circumferential arrays around the center of the working roller 2. The adjacent die-cutting rollers 44 are in contact with each other to form a circular roller, so that the easy-tear line is uninterrupted. The die-cutting rollers 44 can be replaced with rollers with different tooth shapes. The inner wall of the working roller 2 is fixed to the outer surface of the inner layer cylinder 42. The inner layer cylinder 42 and the working roller 2 have three square grooves 43 arranged in the inner circumferential array. The square grooves 43 are arranged along the linear direction of the working roller 2 and penetrate the interior of the inner layer cylinder 42, the working roller 2 and the arc groove 41.

[0039] The die-cutting roller 44 can be rotated and expanded away from the interior of the arc groove 41 by the circular plate 46. In this way, the die-cutting roller 44 is not restricted by the arc groove 41 and slides inside the square groove 43 to select the arc groove 41 at a suitable distance. Then, by rotating the circular plate 46, the position of the arc groove 41 inside the die-cutting roller 44 is limited.

[0040] Reference Figure 4 , Figure 5 The inner walls of the three square grooves 43 are slidably connected to the outer walls of the three connecting rods 45 without gaps, which is used to prevent the connecting rods 45 from shifting. The tops of the three connecting rods 45 are fixedly connected to the bottoms of the three die-cutting rollers 44. The inside of the working roller 2 is slidably connected to the circular plate 46. The outer surface of the circular plate 46 has three arc-shaped through grooves 47 arranged in a circumferential array. The inner walls of the three arc-shaped through grooves 47 are slidably connected to the outer walls of the three first cylinders 48. The three first cylinders 48 are fixed to the end surface of the connecting rods 45 away from the die-cutting rollers 44. The inner wall of the arc-shaped through grooves 47 has a sliding groove 8. A ball bearing 9 is slidably connected inside the sliding groove 8. The outer wall of the ball bearing 9 is fixed to the outer wall of the first cylinder 48. In this way, the sliding groove 8 and the ball bearing 9 prevent the connecting rods 45 from driving the first cylinders 48 out of the arc-shaped through grooves 47 during the process of the connecting rods 45 sliding inside the square grooves 43.

[0041] The rotation of the circular plate 46 causes the first cylinder 48 to slide inside the arc groove 47. The rotation of the first cylinder 48 through the square groove 43 causes the connecting rod 45 to move to the outside of the working roller 2. The connecting rod 45 drives the die-cutting cutter 44 to leave the inside of the arc groove 41, thereby adjusting the position of the die-cutting cutter 44.

[0042] Reference Figure 6 The surface of the center of the circular plate 46 is fixed to the outer side of the second cylinder 49. The second cylinder 49 is rotatably connected to the end of the working roller 2 away from the gear 7. The outer side of the second cylinder 49 is fixed to the mounting end of the handle 410. The handle 410 is located at the end of the second cylinder 49 away from the working roller 2. The handle 410 is used to facilitate the operator to rotate the second cylinder 49. The surface of the second cylinder 49 is provided with a second limiting groove 412. The surface of the working roller 2 is provided with a first limiting groove 411. The first limiting groove 411 is located on the side close to the handle 410. The inner wall of the second limiting groove 412 is slidably connected to the outer wall of the limiting slider 413 without gaps. When the second cylinder 49 is rotated, the limiting slider 413 will not fall out of the second limiting groove 412. The end of the limiting slider 413 located outside the second limiting groove 412 is adapted to the size of the first limiting groove 411. When the limiting slider 413 enters the interior of the first limiting groove 411, the second cylinder 49 cannot rotate.

[0043] The operator rotates the handle 410 to drive the second cylinder 49 to rotate. Before rotation, the limit slider 413 needs to be manually pulled out of the first limit groove 411. The rotation of the second cylinder 49 drives the circular plate 46 to rotate to adjust the position of the die-cutting roller 44. After the position is adjusted, the second cylinder 49 is reversed. When the second limit groove 412 is parallel to the first limit groove 411, the limit slider 413 is moved to insert it into the first limit groove 411 to fix the die-cutting roller 44 and prevent it from moving during operation.

[0044] The drive motor 6 is existing technology, and its structural principle will not be detailed here. The specific model of drive motor 6 is an ABB series servo motor. The servo motor is connected to the servo driver via a cable, and the encoder feedback signal line is connected to the driver to form a closed-loop control. The driver communicates with the PLC through an industrial bus to receive speed and torque commands. During startup, the PLC sends a signal to the driver, and the driver controls the servo motor to rotate. The entire system is connected to the control power supply of the device through wires to achieve precise control of the rolling process.

[0045] The implementation principle of the paper-aluminum-plastic easy-fold roll forming device in this embodiment is as follows: In the initial state, three die-cutting rollers 44 are located inside one of the arc grooves 41, the first cylinder 48 is located at one end of the arc groove 47 near the second cylinder 49, and the limiting slider 413 is located inside the first limiting groove 411. In use, the paper-aluminum-plastic composite material is unwound by the unwinding shaft and fed between the support roller 5 and the working roller 2. The operator starts the drive motor 6 through the controller, and the drive motor 6 drives the support roller 5 to rotate. The support roller 5 drives the working roller 2 to rotate via the gear 7. The rotation of the working roller 2 simultaneously drives the die-cutting blade block 3 and the die-cutting roller 44 to rotate and cooperate with the support roller 5 to cut horizontal and vertical easy-tear lines on the paper-aluminum-plastic composite material. This integrates the horizontal die-cutting blade block 3 and the vertical die-cutting roller 44 onto the same upper roller, enabling the creasing of both horizontal and vertical easy-tear lines in one roll pressing, reducing processing time by at least 50%, and avoiding misalignment of horizontal and vertical creasing caused by positioning errors due to two roll pressings.

[0046] When the position of the die-cutting roller 44 needs to be adjusted, the operator pulls the limiting slider 413 out of the first limiting groove 411. Then, the operator can rotate the second cylinder 49 90 degrees using the handle 410. The rotation of the second cylinder 49 causes the circular plate 46 to rotate 90 degrees, causing the first cylinder 48 to slide at the other end of the arc-shaped through groove 47. The rotation of the first cylinder 48 passes through the square groove 43, causing the connecting rod 45 to move outwards from the working roller 2. The connecting rod 45 then drives the die-cutting roller 44 out of the arc-shaped groove 41. The position of the longitudinal tear line can be adjusted by moving the die-cutting roller 44 and the connecting rod 45. When the die-cutting roller 44 moves to another arc groove 41, the second cylinder 49 is reversed by the operator. The second cylinder 49 moves the die-cutting roller 44 into the arc groove 41 through the circular plate 46. Then the operator inserts the limiting slider 413 into the first limiting groove 411 to fix the position of the die-cutting roller 44 and prevent the die-cutting roller 44 from being unstable when the working roller 2 is working.

[0047] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
