Description

Technical Field

[0001] The invention belongs to the technical field of packaging film processing, and in particular relates to a winding device based on tension adjustment and a winding process for packaging film processing. Background Art

[0002] Packaging Film mainly refers to the film used for packaging articles, usually including polyethylene film, biaxially oriented polyester (BOPET), BOPP film and CPP film, etc., which are mainly used for the packaging of food, medicine and textiles.

[0003] In modern industrial production, packaging film, as an indispensable packaging material, is widely used in many fields such as food, medicine, and daily chemicals. In its processing flow, winding equipment is a key link, and its performance and efficiency directly affect the final quality and production efficiency of the product. Although traditional winding equipment meets the basic winding requirements to a certain extent, it exposes many problems that need to be solved in actual application. These problems not only limit the improvement of production efficiency, but also pose a potential threat to product quality.

[0004] First, due to design limitations, traditional winding equipment is difficult to achieve stable fixation of winding drums of different diameters and lengths, resulting in the winding drum being easily loosened or offset during high-speed rotation. This phenomenon not only affects the neatness and aesthetics of the winding, but is also likely to cause film breakage or overlap, thereby reducing the product qualification rate.

[0005] Secondly, traditional winding equipment also has obvious deficiencies in tension control. Tension is an important parameter in the film winding process, which directly determines the tightness and flatness of the film. However, traditional equipment is often unable to adjust the tension in real time according to factors such as the film material, thickness and running speed. This can easily lead to problems such as bubbles, wrinkles or loose fit between the films, which seriously reduces the overall quality of the product.

[0006] In addition, traditional winding equipment also has certain defects in cleaning. During the film processing, due to environmental factors, some impurities such as dust often adhere to the surface of the film. If these impurities are not removed in time, they will be rolled into the film during the winding process, thus affecting the purity and hygiene standards of the product. Summary of the invention

[0024] A winding process for packaging film processing, applied to the above-mentioned winding device based on tension adjustment, comprises the following steps:

[0025] Step 1: Sleeve the winding drum on the winding part and fix the winding drum by the fixing part, and then install the winding part between the first supporting part and the second supporting part;

[0026] Step 2: When winding, the film passes through the guide roller and the tension roller in sequence, and is finally wound on the winding drum. The motor is started to drive the winding part to rotate and the winding operation is carried out;

[0027] Step 3: During the winding process, the pressing roller is pressed against the outer side of the winding drum to squeeze out bubbles and promote close fitting between film layers; the tension of the film is controlled by adjusting the telescopic length of the first electric push rod;

[0028] Step 4: As the winding diameter increases, the pressing roller pushes the movable plate to move, driving the sleeve plate, L-shaped plate and boss to move. When the boss reaches the maximum stroke, the roller on the movable rod loses its resistance and moves upward under the action of the first compression spring, triggering the contact switch to turn off the motor and stop winding. The winding amount can be changed by adjusting the extended length of the L-shaped plate.

[0029] Step 5: Control the second electric push rod to shorten, remove the winding part, and take down the wound roll.

[0030] The technical effects achieved by the present invention are:

[0031] The present invention adopts an adjustable fixing part design, and realizes the fixation of winding drums of different diameters and lengths through positioning cylinders, positioning circular holes, screw rods and positioning prisms and positioning prism grooves thereon. In addition, the stability of the winding drum during the winding process is ensured by the coordinated work of components such as the disc, the fixing block and the slider. This design not only solves the problem of unstable fixing of the winding drum in traditional equipment, but also greatly expands the practical scope of the equipment. Regardless of how the diameter and length of the winding drum change, stable fixation can be achieved through simple adjustments. This not only improves production efficiency, but also reduces the scrap rate caused by looseness or deviation;

[0032] The present invention achieves the adjustment of film tension through components such as the first electric push rod, the tension roller and the pressing roller. The first electric push rod can be extended and retracted to adjust the position of the tension roller, thereby changing the tension of the film. At the same time, the pressing roller always contacts the outside of the winding drum, exerts pressure on the film, effectively squeezes out the bubbles between the two adjacent layers of film, and makes the films fit more tightly. This tension adjustment mechanism can ensure that the film always maintains appropriate tension during the winding process, avoiding bubbles and loose fit caused by uneven tension. This not only improves the compactness of the winding, but also significantly improves the overall quality of the product;

[0033] The present invention integrates components such as fan blades and filter plates inside the cloth guide roller to form a self-cleaning system. During the rotation process, the winding part drives the first rotating shaft to rotate, and then drives the third transmission gear and the first transmission gear to make the round rod and the fan blades rotate synchronously. In this way, negative pressure is generated inside the cloth guide roller, and the floating dust on the surface of the film is sucked in from the air vents, and collected to the two ends of the cloth guide roller through the guide seat, and blocked by the filter plate. This integrated cleaning structure can remove the floating dust on the surface of the film in real time during the winding process, which significantly improves the cleanliness and quality of the product. After use, the collected floating dust can be conveniently discharged by simply opening the sealing door, and maintenance is simple and efficient;

[0034] The third slide bar on the second U-shaped seat of the present invention is slidably plugged into the horizontal plate, and a second compression spring is sleeved on the outer wall of the third slide bar. As the winding diameter increases, the pressing roller will gradually move toward the horizontal plate and squeeze the second compression spring; the movement of the pressing roller prompts the movable plate to move, thereby driving the sleeve plate, the L-shaped plate and the boss to move. When the boss moves to the maximum stroke, the roller at the upper end of the movable rod loses the resistance force. Under the action of the first compression spring, the roller moves upward and triggers the contact switch, thereby turning off the motor to stop winding; by adjusting the length of the L-shaped plate extending from the sleeve plate, the moving stroke of the boss can be changed, thereby adjusting the amount of each winding. For example, when the L-shaped plate extends longer, a larger stroke is required to trigger the contact switch, thereby increasing the winding amount; conversely, when the L-shaped plate extends shorter, the winding amount is smaller. Through the above mechanism, the amount of each winding can be controlled, avoiding the problem of inconsistent winding amount caused by manual operation or equipment error; the highly consistent winding amount reduces product quality problems caused by differences in winding amount and reduces the scrap rate.

[0080] Next, please refer to Figure 7 , Figure 8and Fig.15 The first supporting part 61 includes a first supporting seat 611, which is fixedly connected to the top surface of the workbench 1. A first rotating shaft 612 is rotatably connected to the first supporting seat 611, and one end of the first rotating shaft 612 is hexagonal. The other end of the first rotating shaft 612 is installed with a third transmission gear 613. The second supporting part 62 includes a second sliding rod 621, which is fixedly connected to the top surface of the workbench 1.

[0085] It should be added that balls are provided inside the upper positioning ring 634 and the lower positioning ring 632 to reduce the friction between the winding portion 64 and the upper positioning ring 634 and the lower positioning ring 632, thereby reducing the transmission resistance and improving the smoothness of the rotation of the winding portion 64;

[0086] It should be noted that the first compression spring 635 is sleeved on the outside of the movable rod 633 , and two ends of the first compression spring 635 are fixedly connected to the upper positioning ring 634 and the support frame 631 respectively.

[0087] Please refer again Fig. 9 , Fig.11 and Fig.12 The winding part 64 includes two hollow cylinders 641, and a docking groove is provided at one end of the hollow cylinders 641. A first sliding groove 642 is provided on both hollow cylinders 641. A positioning circular hole 643 is provided at one end of one hollow cylinder 641, and one end of the other hollow cylinder 641 is connected to a positioning cylinder 644. The interiors of the two hollow cylinders 641 are rotatably connected with a screw rod 645, and a hexagonal groove is provided at one end of the screw rod 645. A positioning prism 646 is connected at one end of one screw rod 645, and a positioning prism groove 647 is provided at one end of the other screw rod 645.

[0088] In this embodiment, the winding drum is sleeved on the two hollow drums 641, and then the positioning cylinder 644 on one hollow drum 641 is accurately inserted into the positioning circular hole 643 on the other hollow drum 641. The stability of the structure is enhanced, and accurate alignment during the winding process is also ensured.

[0089] The positioning prism 646 on one of the screw rods 645 is precisely inserted into the positioning groove 647 on the other screw rod 645. This operation further consolidates the overall structure of the winding section 64, enabling it to withstand a greater workload while ensuring the smoothness and accuracy of the winding action. At this point, the splicing work of the winding section 64 is successfully completed.

[0090] Please refer again Figures 9 to 14The fixing part 65 includes a disc 651, which is slidably connected to the first slide groove 642 on the hollow cylinder 641, and the disc 651 is threadedly connected to the screw rod 645. The disc 651 is provided with a mounting groove 652, and a second slide groove 653 is provided in an annular shape on one side of the disc 651. A slider 654 is slidably connected in the second slide groove 653. A fixing block 655 is fixedly connected to one side of the slider 654, and a force rod 656 is fixedly connected to the other side of the slider 654. A toothed disc 657 is rotatably connected in the mounting groove 652. A guide groove 658 is arranged in a ring shape on the toothed disc 657, and a rotating rod 659 is rotatably connected to the upper end of the mounting groove 652. A fourth transmission gear 6510 is installed at one end of the rotating rod 659 located in the mounting groove 652, and a limit gear 6511 is installed at the other end of the rotating rod 659. A bracket 6512 is fixedly connected to one side of the disc 651, and a moving rod 6513 is slidably inserted on the bracket 6512. A tension spring 6514 is sleeved on the outer wall of the lower end of the moving rod 6513, and a tooth 6515 is fixedly connected to one end of the moving rod 6513.

[0091] In this embodiment, the screw rod 645 is rotated by a hexagonal wrench to drive the two discs 651 to approach each other and clamp the winding drum, while ensuring that the fixed block 655 on the disc 651 can extend into the interior of the winding drum. Subsequently, the staff first pulls the moving rod 6513 upward to make the teeth 6515 rise accordingly, thereby disengaging from the meshing with the limit gear 6511. At this time, the rotating rod 659 is no longer restricted, and the staff can freely rotate the rotating rod 659 to drive the fourth transmission gear 6510 to rotate. The meshing transmission of the fourth transmission gear 6510 and the toothed disc 657 causes the toothed disc 657 to start rotating. During the rotation process, the guide groove 658 applies a resisting force to the force rod 656, prompting the slider 654 to move along the second slide groove 653, so that the multiple sliders 654 are separated from each other. This separation drives the fixed blocks 655 to move away from each other, and the four fixed blocks 655 are in close contact and pressed against the inner wall of the winding drum to achieve a stable fixation of the winding drum.

[0092] After the fixation is completed, the staff releases the moving rod 6513. At this time, the tension spring 6514 plays its resetting role, driving the moving rod 6513 to reset, so that the tooth 6515 is reinserted into the tooth groove of the limit gear 6511, thereby locking the rotating rod 659 to ensure that it cannot rotate again, thereby ensuring the fixing effect of the winding drum and preventing it from loosening.

[0093] The adjustable fixing part 65 enables the winding device to adapt to and fix winding drums of different diameters and lengths, greatly broadening its application range. It is worth mentioning that a rubber ring is specially arranged on the inner wall of the positioning circular hole 643, which not only enhances the damping effect, but also increases the friction force at the connection, effectively preventing the two hollow cylinders 641 from falling off.

[0094] Please refer again Figure 7 The pressing part 66 includes a horizontal plate 661, which is fixedly connected to the top surface of the workbench 1 by a support rod. A third slide bar 662 is slidably inserted on the horizontal plate 661, one end of the third slide bar 662 is fixedly connected to a second U-shaped seat 663, and the other end of the third slide bar 662 is fixedly connected to a movable plate 666. A pressing roller 664 is rotatably connected to the second U-shaped seat 663, and a second compression spring 665 is sleeved on the third slide bar 662.

[0095] In this embodiment, when winding, the film is first passed between the two lower cloth guide rollers 3, then bypasses the tensioning roller 403, and then passes between the two upper cloth guide rollers 3 (such as Fig.18 As shown in the figure, the film is finally wound on the winding drum fixed on the winding section 64. Subsequently, the motor 624 is started to drive the second rotating shaft 625 to rotate, thereby driving the winding section 64 to rotate and rewind. During the entire rewinding process, the pressing roller 664 always tightly contacts the outside of the rewinding drum. Through the pressure exerted on the film, it not only effectively squeezes out the bubbles generated between the two adjacent layers of film during the rewinding process, but also promotes the close fit between the adjacent two films. Such an operation greatly improves the compactness of the rewinding, thereby ensuring the excellence of the rewinding effect.

[0096] Please refer again Figure 7 , Fig.16 and Fig.17 The control part 67 includes a sleeve plate 671, which is fixedly connected to the movable plate 666. An L-shaped plate 672 is slidably inserted at one end of the sleeve plate 671. A boss 673 is fixedly connected to the bottom surface of the L-shaped plate 672. A lock hole 674 is opened on the L-shaped plate 672. A fastening bolt 675 is arranged on the sleeve plate 671. A contact switch 676 is arranged on one of the L-shaped plates 672. In addition, the locking part 68 includes a ratchet 681, which is installed on the first rotating shaft 612. The inner circle of the first support seat 611 is rotatably connected with a pawl 682, and a spring 683 is fixedly connected between the pawl 682 and the first support seat 611.

[0097] In this embodiment, after the winding drum is firmly installed, the user needs to first operate the second electric push rod 623 to shorten it, thereby driving the second support seat 622 to move away from the first support seat 611. The movable plate 666 is pulled to move, and the movement of the movable plate 666 further drives the movement of the sleeve plate 671 and the L-shaped plate 672, causing the boss 673 to release the constraint on the movable rod 633. Subsequently, under the pulling force of the first compression spring 635, the upper positioning ring 634 will be pulled upward. Next, the two ends of the assembled winding portion 64 are securely placed on the lower positioning ring 632, and it is ensured that the prismatic end of the first rotating shaft 612 is accurately inserted into the docking groove at one end of the hollow cylinder 641.

[0098] After completing the above steps, the second electric push rod 623 is controlled to extend again, pushing the second support seat 622 to move toward the first support seat 611, until the prism end of the second rotating shaft 625 is smoothly inserted into the docking groove at one end of the hollow cylinder 641, thereby achieving a stable fixation of the winding section 64. Through the synergistic effect of the upper and lower fixing rings (i.e., the upper positioning ring 634 and the lower positioning ring 632), the stability of the winding section 64 is effectively enhanced, ensuring the smoothness of the winding process.

[0099] In addition, it is worth noting that the third slide bar 662 located on the second U-shaped seat 663 can be slidably inserted on the cross plate 661, and the third slide bar 662 is sleeved with a second compression spring 665 on the outside. As the winding diameter continues to increase, the pressing roller 664 will be pushed to approach the cross plate 661 and squeeze the second compression spring 665. In this process, the movement of the pressing roller 664 will drive the movable plate 666 and the sleeve plate 671, L-shaped plate 672 and boss 673 connected thereto to move together. When the boss 673 reaches the maximum stroke, the roller 636 at the upper end of the movable rod 633 will lose the resistance force, and then under the pulling force of the first compression spring 635, the movable rod 633 will move up until the roller 636 contacts the contact switch 676. The triggering of the contact switch 676 will turn off the motor 624, thereby stopping the winding. This design helps to ensure the consistency of the winding amount each time and reduce errors.

[0100] It should be particularly pointed out that the first compression spring 635 is sleeved on the outside of the movable rod 633, and its two ends are fixedly connected to the upper positioning ring 634 and the support frame 631 respectively. The L-shaped plate 672 is installed inside the sleeve plate 671 by sliding and plugging. When the winding amount needs to be adjusted, the fastening bolt 675 on the sleeve plate 671 can be loosened to make it fall out of the lock hole 674 on the L-shaped plate 672. Then, after pulling the L-shaped plate 672 along the sleeve plate 671 to the desired position, the fastening bolt 675 is screwed into the corresponding lock hole 674 again to complete the fixation. By adjusting the length of the L-shaped plate 672 extending from the sleeve plate 671, the size of the winding amount can be effectively controlled. For example, when the L-shaped plate 672 is extended longer, the boss 673 needs to move a larger stroke to make the roller 636 lose resistance and trigger the contact switch 676 to turn off the motor 624; conversely, if the L-shaped plate 672 is extended shorter, the roller 636 will contact the contact switch 676 faster, and the winding amount will be reduced accordingly.

[0101] After the winding is completed, the second electric push rod 623 is controlled to shorten to move the second support seat 622, and at the same time, the upper positioning ring 634 is ensured to be separated from the winding portion 64. At this time, the user can easily remove the winding portion 64 and the wound roll.

[0102] The ratchet wheel 681 and the pawl 682 are designed to ensure that the winding drum can rotate in one direction, thereby effectively preventing the winding film from loosening due to accidental flipping after winding is completed.

[0103] Secondly, please also refer to Figures 2 to 6 The dust removal component 5 includes a round rod 501, which is rotatably connected to the cloth guide roller 3. The left and right ends of the cloth guide roller 3 are fixedly connected with a guide seat 502 and a filter plate 503, and the filter plate 503 is rotatably connected to the round rod 501. Fan blades 504 are installed at both ends of the round rod 501. Both ends of the cloth guide roller 3 are provided with slag discharge grooves, and sealing doors 505 are provided at the slag discharge grooves, wherein one end of two round rods 501 is installed with a first transmission gear 506, and one end of four round rods 501 is installed with a second transmission gear 507.

[0104] In this embodiment, the winding portion 64 will drive the first rotating shaft 612 to rotate during the rotation process, and the rotation of the first rotating shaft 612 will drive the third transmission gear 613 to rotate. The third transmission gear 613 and the first transmission gear 506 are driven by a toothed belt, thereby driving two of the round rods 501 to rotate, and the corresponding two second transmission gears 507 are also driven by a toothed belt, thereby prompting the four round rods 501 to rotate synchronously.

[0105] As the round rods 501 rotate, they drive the blades 504 to rotate, thereby generating negative pressure inside the cloth guide roller 3. This negative pressure can suck the dust on the surface of the film through the air holes on the cloth guide roller 3, thereby cleaning the film and improving the product quality. The sucked dust will enter the two ends of the cloth guide roller 3 along the guide seat 502 and be effectively blocked by the filter plate 503, so that the dust can be collected together.

[0106] After use, the dust collected in the cloth guide roller 3 can be easily discharged by simply opening the sealing door 505, thereby achieving cleaning and maintenance of the equipment.

[0107] A winding process for packaging film processing, applied to the above-mentioned winding device based on tension adjustment, comprises the following steps:

[0108] Step 1: Sleeve the winding drum on the winding portion 64 and fix the winding drum through the fixing portion 65, and then install the winding portion 64 between the first supporting portion 61 and the second supporting portion 62;

[0109] Step 2: When winding, the film passes through the cloth guide roller 3 and the tension roller 403 in sequence, and is finally wound on the winding drum. The motor 624 is started to drive the winding part 64 to rotate and perform the winding operation;

[0110] Step 3: During the winding process, the pressing roller 664 is pressed against the outer side of the winding drum to squeeze out air bubbles and promote close adhesion between film layers; the tension of the film is controlled by adjusting the telescopic length of the first electric push rod 401;

[0111] Step 4: As the winding diameter increases, the pressing roller 664 pushes the movable plate 666 to move, driving the sleeve plate 671, the L-shaped plate 672 and the boss 673 to move. When the boss 673 reaches the maximum stroke, the roller 636 on the movable rod 633 loses its resistance and moves upward under the action of the first compression spring 635, triggering the contact switch 676 to turn off the motor 624 and stop winding. The winding amount can be changed by adjusting the extension length of the L-shaped plate 672.

[0112] Step 5: Control the second electric push rod 623 to shorten, remove the winding portion 64, and take down the wound roll.

[0113] The working principle of the present invention is:

[0114] Before the formal operation, the winding portion 64 is assembled first, and the winding drum is sleeved on the winding portion 64, and the winding drum is fixed by the fixing portion 65.

[0115] After the winding drum is fixed, the second electric push rod 623 needs to be controlled to shorten, drive the second support seat 622 to move away from the first support seat 611, and pull the movable plate 666. This action will cause the sleeve plate 671 and the L-shaped plate 672 to move, and release the limit of the movable rod 633 by the boss 673. Subsequently, the first compression spring 635 pushes the upper positioning ring 634 upward under the action of tension. At this time, the spliced ​​winding section 64 can be placed on the lower positioning ring 632, and ensure that the prismatic end of the first rotating shaft 612 is accurately inserted into the docking groove at one end of the hollow cylinder 641. Afterwards, the second electric push rod 623 is controlled to extend, and the second support seat 622 is pushed closer to the first support seat 611, so that the prismatic end of the second rotating shaft 625 is also inserted into the docking groove of the hollow cylinder 641, thereby completing the fixing of the winding section 64.

[0116] During the winding operation, the film needs to pass between the two lower guide rollers 3, bypass the tension roller 403, and then pass between the two upper guide rollers 3, and finally be wound on the winding drum. The starter motor 624 will drive the second rotating shaft 625 to rotate, and then drive the winding part 64 to perform the winding operation. During this process, the pressing roller 664 is always close to the outside of the winding drum, effectively squeezing out bubbles and promoting close adhesion between film layers, significantly improving the winding tightness and winding effect.

[0117] By adjusting the telescopic length of the first electric push rod 401, a suitable tension force is applied to the film. As the winding diameter increases, the pressing roller 664 will push the movable plate 666 to move, thereby driving the sleeve plate 671, the L-shaped plate 672 and the boss 673 to move. When the boss 673 reaches the maximum stroke, the roller 636 at the upper end of the movable rod 633 will lose its resistance and move upward under the pulling force of the first compression spring 635, and finally contact the contact switch 676 to turn off the motor 624, thereby achieving precise control of the winding amount.

[0118] In addition, the L-shaped plate 672 and the sleeve plate 671 are designed to be slidably connected, and the winding amount can be adjusted by adjusting the extension length of the L-shaped plate 672. After the winding is completed, the second electric push rod 623 is controlled to shorten and remove the winding part 64, so that the wound roll can be easily removed.

[0119] It is worth noting that the rotation of the winding part 64 will drive the first rotating shaft 612 and the third transmission gear 613 to rotate, and then drive the four round rods 501 to rotate synchronously through the toothed belt transmission. The rotation of the round rod 501 will cause the fan blade 504 to rotate, generate negative pressure inside the cloth guide roller 3, and effectively absorb the floating dust on the surface of the film. The floating dust will be directed to the two ends of the cloth guide roller 3 and intercepted and collected by the filter plate 503. After use, the sealing door 505 can be opened to discharge the collected floating dust.

[0120] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
