Description

Technical Field

[0001] This utility model relates to the field of membrane material processing, specifically to a device for eliminating static electricity during membrane discharge at a multi-packing machine membrane station. Background Technology

[0002] In the process of extruding film at a multi-packaging film station, the film needs to be guided and conveyed by multiple sets of rollers to complete subsequent packaging and other processes. However, in existing technologies, when the film is guided by the roller sets, static electricity is easily generated due to unavoidable friction between the film and the rollers. This static electricity causes the surface of the film to become charged, resulting in adsorption forces between the film materials or between the film and other components, preventing the film from being extruded smoothly from the film station. When the static electricity accumulates to a certain level, the film will exhibit obvious shrinkage during the extrusion process, meaning that the film cannot be extruded smoothly along the preset path and length, but instead shrinks and curls.

[0003] This shrinkage phenomenon severely impacts the normal operating efficiency of multi-packaging machines. Insufficient film extrusion disrupts subsequent packaging processes, requiring frequent machine stops for adjustments, increasing production downtime, and slowing overall production progress. Furthermore, shrinkage affects packaging quality. The shrunken film cannot cover the packaged items evenly and smoothly, potentially resulting in loose packaging, wrinkles, and reduced product appearance and sealing.

[0004] Furthermore, due to the presence of static electricity, the membrane material easily attracts dust and impurities from the air during transportation, further affecting its cleanliness. For products with high requirements for packaging environment, this contamination may lead to product defects. Moreover, long-term static electricity problems may also interfere with or damage the electronic components of the equipment, shortening its lifespan and increasing maintenance costs.

[0005] Currently, there is a lack of effective solutions to the problem of film ejection caused by static electricity. Most solutions can only temporarily alleviate the problem by manually cleaning or adjusting the rollers periodically, but they cannot fundamentally solve the problem of static electricity generation and film shrinkage, which has caused great trouble to the stable operation of multi-packing machines and product quality. Utility Model Content

[0006] Therefore, it is necessary to provide a device for eliminating static electricity during film discharge at a multi-packing machine film station, addressing the existing technical problems.

[0007] To solve the problems of the existing technology, the technical solution adopted by this utility model is as follows:

[0008] A multi-pack film station electrostatic elimination device includes:

[0009] The lower end is rotatably equipped with a support roller, and above the support roller is a drive roller driven by a main motor. A driven roller is rotatably equipped next to the drive roller, and the driven roller rotates in the opposite direction to the drive roller. Above the driven roller is a guide roller driven by an auxiliary motor.

[0010] An electrostatic eliminator is installed on the side of the guide roller;

[0011] The membrane material moves sequentially along the carrying roller, the driving roller, the driven roller, and the guide roller;

[0012] A guide mechanism is provided on the side of the driven roller. The guide mechanism includes a guide seat that is adjustablely connected to the bracket. Wheel seats are arranged in an evenly spaced array along the long side of the upper end of the guide seat. A roller that abuts against the membrane material is provided on the side of the wheel seat that is close to the membrane material.

[0013] Furthermore, the two ends of the drive roller are coaxially fixed with main pulleys, and a secondary pulley is rotatably arranged on the side of each main pulley. The main pulleys and secondary pulleys are connected by belt drive.

[0014] The auxiliary pulley is coaxially fixed to the main gear, and the driven roller is coaxially fixed to the two ends of the auxiliary gear. The main gear and the auxiliary gear mesh with each other.

[0015] Furthermore, cylinders are provided at both ends of the guide seat. The fixed end of the cylinder is fixed to the side wall of the bracket by bolts, and the output end of the cylinder is fixed to the guide seat.

[0016] Furthermore, a support platform is provided at the bottom of each end of the guide seat. The support platform is fixedly connected to the bracket. A slide rail is fixedly connected to the upper end of the support platform. A slide table is slidably connected to the slide rail. The slide table is fixedly connected to the lower end of the guide seat.

[0017] Furthermore, a guide rail is fixedly connected to the upper end of the guide seat, and a guide block is slidably connected to the upper end of the guide rail. The guide block is fixedly connected to the lower end of the wheel seat.

[0018] A main rotating rod is screwed to the upper end of the wheel seat. After the main rotating rod is tightened, its lower end abuts against the upper end of the guide seat.

[0019] Furthermore, a wheel frame is slidably connected to the middle of the wheel seat, and the end of the wheel frame is rotatably connected to the roller;

[0020] A main rotating rod is installed on the side of the main rotating rod. After the main rotating rod is screwed to the wheel seat and tightened, its lower end abuts against the upper end of the wheel frame.

[0021] Furthermore, the rollers are formed with anti-slip grooves at equal angles along the circumference.

[0022] The advantages of this utility model compared with the prior art are:

[0023] Firstly, this device, by setting up an electrostatic eliminator, can effectively eliminate the static electricity generated by friction when the membrane material is guided by the roller group, avoiding problems such as membrane material adsorption and adhesion caused by static electricity, fundamentally solving the membrane shrinkage phenomenon, ensuring that the membrane material can be smoothly extruded, improving the working efficiency of the multi-pack machine, and reducing the downtime adjustment time caused by poor membrane material extrusion.

[0024] Secondly, the active roller and driven roller in this device achieve reverse rotation through the cooperation of the main pulley, auxiliary pulley, belt, and main gear and auxiliary gear, forming a stable reverse clamping force, which effectively eliminates the loosening of the membrane material, ensures stable tension during the conveying process, avoids further aggravation of static electricity generation and film shrinkage due to membrane material loosening, ensures the stability of membrane material conveying, and solves the problem of unstable membrane material conveying in the background technology.

[0025] Thirdly, the guiding mechanism in this device can be flexibly adjusted according to the width of the membrane material. The cylinder drives the guide seat to move, and the slide rail and slide table ensure smooth movement. The position and tightness of the wheel seat and roller can be precisely adjusted, and the anti-slip groove of the roller prevents slippage. It effectively positions the membrane material laterally, prevents the membrane material from shifting, ensures that the membrane material is accurately aligned with each component, and avoids increased friction and static electricity caused by shifting.

[0035] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0036] refer to Figures 1 to 7 A multi-pack film station electrostatic elimination device, comprising:

[0037] The lower end is rotatably equipped with a bracket 1 for carrying roller 3. Above the carrying roller 3, a drive roller 5 driven by a main motor 4 is rotatably equipped. A driven roller 7 is rotatably equipped on the side of the drive roller 5. The driven roller 7 rotates in the opposite direction to the drive roller 5. Above the driven roller 7, a guide roller 26 driven by an auxiliary motor 28 is rotatably equipped.

[0038] An electrostatic eliminator 27 is provided on the side of the guide roller 26;

[0039] The membrane material 2 moves sequentially along the carrying roller 3, the driving roller 5, the driven roller 7 and the guide roller 26;

[0040] A guide mechanism 11 is provided on the side of the driven roller 7. The guide mechanism 11 includes a guide seat 14 that is adjustablely connected to the bracket 1. Wheel seats 17 are arranged at equal intervals along the long side of the upper end of the guide seat 14. A roller 19 that abuts against the membrane material 2 is provided on the side of the wheel seat 17 near the membrane material 2.

[0041] During operation, the support roller 3 provides initial support for the membrane material 2 through its own rotation. After being drawn out from the support roller 3, the membrane material 2 enters the clamping area between the drive roller 5 and the driven roller 7. The main motor 4 drives the drive roller 5 to rotate. Since the driven roller 7 rotates in the opposite direction to the drive roller 5, the two form a reverse clamping force. The friction force is used to drive the membrane material 2 forward. At the same time, the clamping action eliminates the slack of the membrane material 2, ensuring stable tension during the conveying process.

[0042] After being conveyed by the driving roller 5 and the driven roller 7, the membrane material 2 enters the guide roller 26. The auxiliary motor 28 drives the guide roller 26 to rotate. The rotation speed of the guide roller 26 can be adjusted according to the conveying requirements of the membrane material 2, matching the speed of the driving roller 5 and the driven roller 7 to prevent the membrane material 2 from being stretched or wrinkled due to speed differences. The guiding effect of the guide roller 26 keeps the membrane material 2 on the preset path, providing a stable processing posture for the subsequent static elimination process.

[0043] Next to the guide roller 26, the static eliminator 27 works synchronously. When the membrane material 2 passes through the effective range of the static eliminator 27, the positive and negative ions released by it neutralize the static charge generated on the surface of the membrane material 2 due to friction, quickly eliminating the accumulation of static electricity on the surface of the membrane material 2, and fundamentally avoiding problems such as dust adsorption, membrane material 2 adhesion or edge curling caused by static electricity, thus ensuring the cleanliness and physical stability of the membrane material 2 surface.

[0044] To further improve conveying accuracy, the guide mechanism 11 beside the driven roller 7 plays a lateral positioning role. The adjustable connection design between the guide seat 14 and the bracket 1 allows the position to be adjusted according to the width of the membrane material 2, so that the roller 19 on the wheel seat 17 precisely fits the edge of the membrane material 2. During the conveying process of the membrane material 2, the roller 19 rotates as the membrane material 2 moves, forming a lateral constraint on the membrane material 2 through flexible contact, preventing it from deviating due to conveying deviation, and ensuring that the membrane material 2 always moves along the predetermined path and maintains precise alignment with each roller group and the static eliminator 27.

[0045] In order to achieve opposite rotations between the driven roller 7 and the driving roller 5, the following features are specifically provided:

[0046] The two ends of the drive roller 5 are coaxially fixed with main pulleys 6, and auxiliary pulleys 8 are rotatably arranged on the side of each main pulley 6. The main pulleys 6 and auxiliary pulleys 8 are connected by belt drive.

[0047] The auxiliary pulley 8 is coaxially fixed to the main gear 9, and the two ends of the driven roller 7 are coaxially fixed to the auxiliary gears 10 respectively. The main gear 9 and the auxiliary gears 10 mesh with each other.

[0048] When the main motor 4 drives the drive roller 5 to rotate, the main pulleys 6 at both ends of the drive roller 5 rotate together. The main pulleys 6 drive the auxiliary pulleys 8 on the side to rotate synchronously through the belt. The main gear 9, which is fixedly connected to the auxiliary pulley 8 on the same axis, rotates accordingly. Since the main gear 9 meshes with the auxiliary gears 10 at both ends of the driven roller 7, the auxiliary gears 10 generate rotation in the opposite direction to the main gear 9, thereby driving the driven roller 7 to rotate in the opposite direction to the drive roller 5. This ensures that the drive roller 5 and the driven roller 7 form a reverse clamping force, stably conveying the film material 2.

[0049] In order to facilitate the movement of the guide seat 14, the following features are also provided:

[0050] Cylinders 12 are respectively provided at both ends of the guide seat 14. The fixed end of the cylinder 12 is fixedly connected to the side wall of the bracket 1 by bolts 13, and the output end of the cylinder 12 is fixedly connected to the guide seat 14.

[0051] When the position of the guide seat 14 needs to be adjusted according to the width of the membrane material 2, the cylinder 12 is activated. The output end of the cylinder 12 extends or retracts, thereby moving the guide seat 14 fixed thereto. The fixed end of the cylinder 12 is firmly connected to the side wall of the bracket 1, ensuring the stability and accuracy of the guide seat 14 during movement. It can quickly and accurately adjust the guide seat 14 to a position that matches the width of the membrane material 2, ensuring that the roller 19 can accurately fit the edge of the membrane material 2.

[0052] In order to limit the movement of the guide seat 14, the following features are specifically provided:

[0053] The guide seat 14 has a support platform 25 at each end. The support platform 25 is fixedly connected to the bracket 1. The upper end of the support platform 25 is fixedly connected to the slide rail 24. The slide rail 24 is slidably connected to the slide table 23. The slide table 23 is fixedly connected to the lower end of the guide seat 14.

[0054] When the cylinder 12 pushes the guide seat 14 to move, the slide 23, which is fixed to the lower end of the guide seat 14, slides along the slide rail 24, which is fixed to the upper end of the support platform 25. The slide rail 24 restricts the movement path of the slide 23, preventing the guide seat 14 from deviating or shaking during movement, and ensuring that the guide seat 14 always moves smoothly along the preset direction. At the same time, the support platform 25 provides a stable support for the slide rail 24 and the slide 23, further enhancing the stability of the guide seat 14 during movement and ensuring that the guiding mechanism 11 can accurately perform its lateral positioning function.

[0055] In order to adjust the position of the wheel seat 17 so as to adjust the position of the roller 19, the following features are also provided:

[0056] The upper end of the guide seat 14 is fixedly connected to the guide rail 15, the upper end of the guide rail 15 is slidably connected to the guide block 16, and the guide block 16 is fixedly connected to the lower end of the wheel seat 17.

[0057] A main rotating rod 22 is screwed onto the upper end of the wheel seat 17. After the main rotating rod 22 is tightened, its lower end abuts against the upper end of the guide seat 14.

[0058] When the position of the wheel seat 17 needs to be adjusted to accommodate the width of the membrane material 2, the operator releases the main rotating rod 22 and pushes the wheel seat 17. The guide block 16, which is fixed to the lower end of the wheel seat 17, slides along the guide rail 15 at the upper end of the guide seat 14, thereby moving the wheel seat 17. After the wheel seat 17 moves to the appropriate position, the operator tightens the main rotating rod 22 so that the lower end of the main rotating rod 22 abuts against the upper end of the guide seat 14. The friction force is used to fix the wheel seat 17, preventing it from shifting during the conveying of the membrane material 2 and ensuring that the roller 19 can always accurately abut against the membrane material 2.

[0059] In order to adjust the tightness between the roller 19 and the membrane material 2, the following features are also provided:

[0060] A wheel frame 18 is slidably connected to the middle of the wheel seat 17, and the end of the wheel frame 18 is rotatably connected to the roller 19;

[0061] A main rotating rod 21 is provided on the side of the main rotating rod 22. After the main rotating rod 21 is screwed to the wheel seat 17 and tightened, its lower end abuts against the upper end of the wheel frame 18.

[0062] When adjusting the tightness between roller 19 and membrane material 2, the operator loosens the main rotating rod 21, allowing the wheel frame 18 to slide up and down in the middle of the wheel seat 17, thus changing the distance between roller 19 and membrane material 2. Once the appropriate tightness is achieved, the operator tightens the main rotating rod 21, causing its lower end to abut against the upper end of the wheel frame 18, fixing the wheel frame 18 and thus the position of roller 19. In this way, the tightness of roller 19 against membrane material 2 can be precisely adjusted according to its thickness, material properties, etc., ensuring both effective restraint of membrane material 2 and preventing damage due to excessive force.

[0063] To prevent roller 19 from slipping, the following features are specifically designed:

[0064] The roller 19 has anti-slip grooves 20 formed at equal angles along the circumference.

[0065] During the conveying process of membrane material 2, roller 19 rotates as membrane material 2 moves. The anti-slip grooves 20 on the circumference of roller 19 increase the friction between roller 19 and the edge of membrane material 2, effectively preventing relative slippage between them. This makes the positioning constraint of roller 19 on membrane material 2 more reliable, ensuring that membrane material 2 will not deviate due to slippage of roller 19 during the conveying process, further ensuring that membrane material 2 moves stably along the predetermined path and maintains precise alignment with each roller group and static eliminator 27.

[0066] The detailed working principle of this device is as follows: After the equipment is started, the membrane material 2 is first placed on the support roller 3. The support roller 3 provides initial support and guidance for the membrane material 2 through its own rotation, allowing the membrane material 2 to be smoothly led out and enter the clamping area between the drive roller 5 and the driven roller 7. The main motor 4 starts and drives the drive roller 5 to rotate. The main pulleys 6 at both ends of the drive roller 5 rotate together with the drive roller 5. The main pulleys 6 drive the auxiliary pulleys 8 to rotate through the belt. The main gear 9, which is fixedly connected to the auxiliary pulley 8 on the same axis, rotates accordingly. The main gear 9 meshes with the auxiliary gears 10 at both ends of the driven roller 7, so that the driven roller 7 rotates in the opposite direction to the drive roller 5. The two form a reverse clamping force, which uses friction to drive the membrane material 2 forward. At the same time, the clamping action eliminates the slack of the membrane material 2, ensuring the tension is stable during the conveying process.

[0067] After being conveyed by the active roller 5 and the driven roller 7, the membrane material 2 enters the area of ​​the guide roller 26. The auxiliary motor 28 drives the guide roller 26 to rotate. Its speed can be adjusted according to the conveying requirements of the membrane material 2, and it matches the speed of the active roller 5 and the driven roller 7 to avoid stretching or wrinkling of the membrane material 2 due to speed difference. The guiding effect of the guide roller 26 keeps the membrane material 2 on the preset path, providing a stable processing posture for the subsequent static elimination process.

[0068] Next to the guide roller 26, the static eliminator 27 works synchronously. When the membrane material 2 passes through the effective range of the static eliminator 27, the positive and negative ions it releases neutralize the static charge generated on the surface of the membrane material 2 due to friction, quickly eliminating the accumulation of static electricity on the surface of the membrane material 2 and avoiding various problems caused by static electricity from the root.

[0069] Meanwhile, the guide mechanism 11 beside the driven roller 7 plays a lateral positioning role. According to the width and tension of the film material 2, the cylinder 12 is pneumatic and its output end drives the guide seat 14 to move. The slide table 23 at the lower end of the guide seat 14 slides along the slide rail 24 at the upper end of the support table 25 to ensure that the guide seat 14 moves smoothly to the appropriate position.

[0070] Before this, the operator needs to preset the specific position of the roller 19. The operator needs to first loosen the main rotating rod 22, push the wheel seat 17, and make the guide block 16 slide along the guide rail 15 to adjust the wheel seat 17 to the position of the corresponding edge of the membrane material 2, and then tighten the main rotating rod 22 to fix the wheel seat 17.

[0071] If it is necessary to adjust the tightness between roller 19 and membrane material 2, the operator loosens the main rotating rod 21, moves the sliding wheel frame 18 to the appropriate position, and then tightens the main rotating rod 21 to fix it. During the conveying process of membrane material 2, roller 19 rotates as membrane material 2 moves. The anti-slip groove 20 on its circumference increases the friction with the edge of membrane material 2 to prevent slippage. Through flexible contact, it forms a lateral constraint on membrane material 2 to prevent membrane material 2 from deviating and ensures that membrane material 2 always moves along the predetermined path and maintains precise alignment with the carrying roller 3, driving roller 5, driven roller 7, guide roller 26, and static eliminator 27.

[0072] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
