Description

Technical Field

[0001] This utility model relates to the field of pearlescent film slitting and winding technology, specifically a pearlescent film winding mechanism for multi-roll synchronous slitting. Background Technology

[0002] Pearl film is a BOPP film produced by adding pearl pigments to plastic particles and then undergoing biaxial stretching and heat setting. Pearl film slitting and winding refers to cutting a wide pearl film into several narrow pearl film widths according to production requirements, and then winding the slitting narrow pearl film widths into rolls of finished products that meet specifications for subsequent storage, transportation and use.

[0003] For example, patent CN217756075U discloses a slitting and winding mechanism that can simultaneously wind up multiple rolls of plastic. It includes a base plate. Through the structural design of the disassembly and assembly mechanism, when the winding roller needs to be replaced, rotating the rotating block drives the bidirectional threaded rod to rotate. The bidirectional threaded rod drives two moving plates to the center, and the moving plates drive the arc-shaped plate to the center, so that the arc-shaped plate does not contact the inner wall of the winding roller, and the baffle no longer obstructs the winding roller. The winding roller can then be removed from one end of the rotating roller. A new winding roller is then fitted onto the surface of the rotating roller, with one end of the winding roller abutting against the L-shaped plate. Rotating the rotating block drives the two… The curved plate abuts against the inner wall of the take-up roller, and the baffle also blocks the take-up roller, thus completing the fixation. This enables quick and convenient replacement of the take-up roller, solving the problem of inconvenient disassembly and assembly of the take-up roller in most current take-up mechanisms, and improving the efficiency of the take-up mechanism. In this case, the fixation of the take-up roller relies on the contact between the curved plate and the inner wall of the take-up roller and the obstruction of the baffle. During high-speed take-up, the take-up roller is easily affected by large centrifugal force and tension. The friction between the curved plate and the inner wall of the take-up roller may not be sufficient to resist these forces, causing the take-up roller to slip or wobble slightly during rotation, affecting the flatness and tightness of the take-up, and reducing the take-up quality.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing multi-roll synchronous slitting pearlescent film winding mechanism. Utility Model Content

[0005] The purpose of this invention is to provide a multi-roll synchronous slitting pearlescent film winding mechanism to solve the problem mentioned in the background art that during high-speed winding, the winding roller is easily affected by large centrifugal force and tension, and the friction between the arc plate and the inner wall of the winding roller may not be sufficient to resist these forces, resulting in slight slippage or shaking of the winding roller during rotation, affecting the flatness and tightness of the winding, and reducing the winding quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-roll synchronous slitting pearlescent film winding mechanism, comprising a base, a cutting cover mounted on the top of the base, a support seat slidably connected to one side of the top of the base, a conveying roller rotatably connected inside the support seat, and a discharge roller rotatably connected to the other end of the top of the base via a support plate; a drive box mounted on one side of the cutting cover, a rotating shaft mounted on the output end of the drive box, a cutting blade mounted on the outer wall of the rotating shaft, and four sets of conveying rollers symmetrically mounted inside the cutting cover; and a slitting mechanism for multi-roll slitting is provided on the support seat.

[0007] Furthermore, the slitting mechanism includes a rotating roller, which is rotatably connected between two support seats. Rotating seats are fixedly connected to the outer walls at both ends of the rotating roller. Sliding blocks are slidably connected inside the two rotating seats, and a sliding shaft is fixedly connected to one side of the sliding block.

[0008] Furthermore, rotating sleeves are rotatably connected to the sliding block, the rotating seat on one side, and the support seat on one side. A fixing strip is provided at one end of the rotating roller, the splitting shaft, and the conveying roller near the rotating sleeve. A slot corresponding to the fixing strip is provided inside the rotating sleeve.

[0009] Furthermore, a synchronous pulley is installed at one end of both the conveying roller and the reel, and a synchronous belt is provided between the synchronous pulleys. Springs are fixedly connected to the top and bottom of the sliding block, and the ends of the two springs that are far apart from each other are fixedly connected to the inside of the rotating seat.

[0010] Furthermore, a worm gear is fixedly connected to one end of the rotating roller, and a worm is rotatably connected to the support seat on one side via a bracket. The worm and the worm gear mesh with each other. A bidirectional lead screw is rotatably connected to the inside of one side of the base, and the bottom of the support seat is threaded to the outer walls of both ends of the bidirectional lead screw.

[0011] Furthermore, a correction mechanism for correcting the pearlescent film is provided on the other side of the top of the base. The correction mechanism includes a monitoring roller, which is mounted on the top of the base via a support arm. An adjusting roller is also rotatably connected to the top of the base via a bracket. An electric push rod is installed on the other side of the top of the base. The output end of the electric push rod is rotatably connected to one end of the adjusting roller. A displacement sensor is provided on the monitoring roller.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This multi-roll synchronous slitting pearlescent film winding mechanism, when multiple rolls of film need to be cut synchronously, uses the cooperation of synchronous pulleys and synchronous belts to make the conveyor rollers and slitting shafts rotate synchronously, achieving stable conveying of the pearlescent film. When synchronization is not required, the worm gear can be rotated to drive the worm wheel, which in turn causes the rotating rollers and rotating seats to rotate, allowing the slitting shafts to move around the rotating rollers in a circular motion. Under the action of the synchronous belt, the sliding block compresses the spring to ensure that the conveyor rollers continuously drive the slitting shafts to rotate, achieving tension adjustment.

[0014] Furthermore, during the film winding process, the monitoring roller monitors the conveying position of the pearlescent film in real time. When a deviation occurs, the monitoring roller transmits a signal to the control center, which then controls the electric push rod to start, causing the adjusting roller to rotate at a certain angle and adjust the conveying angle of the pearlescent film to return it to the correct position. This timely correction of film deviation effectively avoids winding quality problems caused by deviation, thereby improving the product's pass rate and quality stability.

[0015] Furthermore, in terms of film replacement or installation, the spacing between the support seats can be adjusted by rotating the bidirectional screw to facilitate film roll installation. After installation, rotating the support seat causes the rotating sleeve to abut against the conveyor roller, rotating roller and rewinding shaft. The ends are fixed by fixing strips and slots to ensure film stability. The operation is simple and efficient. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 This utility model provides the following technical solution: a multi-roll synchronous slitting pearlescent film winding mechanism, including a base 1, a cutting cover 2 installed on the top of the base 1, a support seat 3 slidably connected to one side of the top of the base 1, a conveying roller 4 rotatably connected inside the support seat 3, and a discharge roller 5 rotatably connected to the other end of the top of the base 1 via a support plate; a drive box 6 is installed on one side of the cutting cover 2, a rotating shaft is installed at the output end of the drive box 6, a cutting blade 7 is installed on the outer wall of the rotating shaft, and four sets of conveying rollers 21 are symmetrically installed inside the cutting cover 2; a slitting mechanism for multi-roll slitting is provided on the support seat 3; the slitting mechanism includes a rotating roller 9, the rotating roller 9 is rotatably connected between two support seats 3, rotating seats 8 are fixedly connected to the outer walls of both ends of the rotating roller 9, sliding blocks 16 are slidably connected inside the two rotating seats 8, and one side of the sliding block 16 is fixedly connected to... There is a reel 12; a rotating sleeve 13 is rotatably connected to a sliding block 16, a rotating seat 8 on one side, and a support seat 3 on one side; a fixing strip is provided at one end of the rotating roller 9, the reel 12, and the conveying roller 4 near the rotating sleeve 13; a groove corresponding to the fixing strip is provided inside the rotating sleeve 13; a synchronous wheel 15 is installed at one end of the conveying roller 4 and the reel 12; a synchronous belt is provided between the synchronous wheels 15; springs 14 are fixedly connected to the top and bottom of the sliding block 16; the ends of the two springs 14 that are far apart from each other are fixedly connected to the inside of the rotating seat 8; a worm gear 10 is fixedly connected to one end of the rotating roller 9; a worm 11 is rotatably connected to one side of the support seat 3 through a bracket; the worm 11 and the worm gear 10 mesh with each other; a double-acting screw 17 is rotatably connected inside one side of the base 1; and the bottom of the support seat 3 is threaded to the outer walls of both ends of the double-acting screw 17.

[0025] When using it, first determine whether multiple rolls of film need to be cut simultaneously, such as... Figure 1 and Figure 2 As shown, when needed, the film material can be mounted on the conveyor roller 4 and the rewinding shaft 12 respectively, and then driven by the conveyor roller 4, as... Figure 3 and Figure 5As shown, since one end of each of the two sliding blocks 16 is equipped with a synchronous pulley 15, and a synchronous belt is provided between the two synchronous pulleys 15, the conveyor roller 4 will also rotate synchronously with the rotation of the reel shaft 12, thereby realizing the conveying of the pearlescent film. When not needed, as... Figure 3 and Figure 4 As shown, the worm 11, which is rotatably connected to the support 3 on one side via the bracket, can be rotated. When the worm 11 rotates, it meshes with the worm wheel 10, which is fixedly connected to one end of the rotating roller 9. Therefore, the rotation of the worm 11 drives the worm wheel 10 to rotate, thereby causing the rotating roller 9 to rotate. Figure 3 and Figure 4 As shown, since rotating seats 8 are fixedly connected to the outer walls of both ends of the rotating roller 9, the rotation of the rotating roller 9 will drive the rotating seats 8 to rotate synchronously. The splitting shaft 12 is set on the rotating seat 8 on one side, so the rotation of the rotating seat 8 will drive the splitting shaft 12 to rotate synchronously. When the splitting shaft 12 rotates under the drive of the rotating seat 8, since a synchronous belt is set between the two synchronous pulleys 15, the relative distance between the splitting shaft 12 and the conveying roller 4 will not change under the action of the synchronous belt. Therefore, when the splitting shaft 12 moves around the circumference of the rotating roller 9, the synchronous belt will drive the sliding block 16 on one side to move, as shown. Figure 3 and Figure 5 As shown, since springs 14 are fixedly connected to both the top and bottom of the sliding block 16, and the ends of the two springs 14 that are far apart from each other are fixedly connected to the inside of the rotating seat 8, the sliding block 16 will compress the spring 14 at its bottom. This ensures that after the rotating seat 8 rotates, the conveying roller 4 can continuously drive the reel 12 to rotate. When the reel 12 rotates to a suitable angle, the film material on the conveying roller 4 can be passed around the reel 12, so that the reel 12 can act as a tensioning wheel when no film material is placed on it. Figure 3 and Figure 4 As shown, when it is necessary to replace or install the membrane material, the bidirectional lead screw 17, which is internally connected to one side of the base 1, can be rotated first. When the bidirectional lead screw 17 rotates, as shown... Figure 3 and Figure 4 As shown, since the bottom of the support seat 3 is threaded to the outer walls of both ends of the bidirectional lead screw 17, the rotation of the bidirectional lead screw 17 will cause the two support seats 3 to slide towards or away from each other on the top of the base 1, thereby adjusting the distance between the two support seats 3, so that the film roll can be installed on the conveyor roller 4, as shown. Figure 3 and Figure 5As shown, after installation, the support base 3 can be rotated in the opposite direction. Then, the rotating sleeve 13 on the support base 3 and rotating base 8 on the other side will gradually come into contact with the conveying roller 4, rotating roller 9 and reel 12. Since the rotating roller 9, reel 12 and conveying roller 4 are provided with a fixing strip at one end near the rotating sleeve 13, and the rotating sleeve 13 is provided with a slot corresponding to the fixing strip inside, when the rotating sleeve 13 moves to the appropriate position, the fixing strip is inserted into the slot, fixing the ends of the rotating roller 9, reel 12 and conveying roller 4. This ensures that the film material will not fall off easily, while ensuring that the driving component can drive the rotating roller 9, reel 12 and conveying roller 4 to rotate.

[0026] Example 2: Please refer to Figure 1 , Figure 2 and Figure 5 Based on Embodiment 1, a correction mechanism is also disclosed, the specific structure of which is as follows:

[0027] The correction mechanism includes a monitoring roller 18, which is mounted on the top of the base 1 via a support arm. An adjusting roller 19 is also rotatably connected to the top of the base 1 via a bracket. An electric push rod 20 is mounted on the other side of the top of the base 1. The output end of the electric push rod 20 is rotatably connected to one end of the adjusting roller 19. A displacement sensor is provided on the monitoring roller 18.

[0028] And once the membrane material is installed, such as Figure 1 and Figure 2 As shown, the film material is wound around the spool 12 and then onto the transfer roller 21. The film material is then placed between the two monitoring rollers 18, then wound around the surface of the adjusting roller 19, and finally onto the output roller 5 to achieve winding. Figure 1 and Figure 5 As shown, when the film material is wound up, the displacement sensor on the monitoring roller 18 is used to monitor the position of the pearl film during the conveying process. When the pearl film deviates during the conveying process, it will transmit a signal to the control center. The control center controls the electric push rod 20 to start, so that the extension and retraction of the electric push rod 20 drives the adjusting roller 19 to tilt at a certain angle, thereby adjusting the conveying angle of the pearl film and returning it to the correct position, thus realizing the correction function.
