Description

Technical Field

[0001] This utility model relates to the field of film production technology, and in particular to a slitting edge material winding device. Background Technology

[0002] In the film production process, a certain width of edge material needs to be cut off from the film during the film winding process, and then the edge material needs to be wound up. Currently, edge material winding is mainly achieved by direct speed regulation of the motor. This method can achieve edge material collection by adjusting the motor speed. However, it is essential to ensure that the edge material winding speed is completely consistent with the production line speed. If the speed difference exists, edge material breakage or difficulty in winding will occur. Conversely, if the winding speed is consistent with the production line speed, the winding tightness cannot be adjusted. Utility Model Content

The third drive component is used to drive the first pressure roller to rotate around its own axis. The lower side of the second pressure roller can abut against the upper side of the take-up roller.

[0005] According to some embodiments of the present invention, the traction assembly further includes a first cylinder, the drive end of the first cylinder facing upward and fixedly connected to the slide block, the first cylinder continuously applying a downward force to the slide block.

[0006] According to some embodiments of the present invention, the slitting edge material winding device further includes an auxiliary component, which includes a swing arm and an auxiliary pressure roller. The swing arm is rotatably connected to the slide block, and the auxiliary pressure roller is rotatably connected to the swing arm. The auxiliary pressure roller can rotate around its own axis. The rotation of the swing arm can drive the auxiliary pressure roller to swing above the pressure roller and make the lower side of the auxiliary pressure roller abut against the pressure roller.

[0007] According to some embodiments of the present invention, the traction assembly further includes a second cylinder and a mounting frame. The second cylinder is mounted on the traction frame, with the drive end of the second cylinder facing downwards. The drive end of the second cylinder is fixedly connected to the mounting frame, and the second pressure roller is rotatably connected to the mounting frame.

[0008] According to some embodiments of the present invention, the traction frame is slidably connected to the frame in the front-to-back direction, and the traction assembly further includes a fourth driving component, which is used to drive the traction frame to move in the front-to-back direction.

[0009] According to some embodiments of the present invention, the traction assembly further includes a roller, which is rotatably connected to the traction frame and is located below the first pressure roller.

[0010] According to some embodiments of the present invention, the traction assembly further includes a first traction wheel, which is rotatably connected to the traction frame and is located to the left of the roller and to the right of the pressure roller.

[0011] According to some embodiments of the present invention, the traction assembly further includes two first guide rods, which are fixedly installed on the traction frame. The two first guide rods are spaced apart in the front-rear direction, and the first guide rods are located between the first traction wheel and the roller.

[0012] According to some embodiments of the present invention, the traction assembly further includes a swing frame, a third cylinder, and a second traction wheel.

The linear speeds of the take-up roller and the pressure roller are the same but in opposite directions. The first and second pressure rollers work together to pull the edge material from the production line equipment to the take-up roller. The linear speed of the third drive component is consistent with the production line speed, thereby ensuring that the edge material between the first pressure roller and the production line equipment is always in a taut state. This prevents the edge material from being loose and unable to be accurately and evenly cut during the cutting process of the film roll, which would result in uneven gaps in the edge material and make it easy to tear.

[0015] 2. The edge material between the first pressure roller and the take-up roller can be in a taut or loose state. During the take-up process, the first drive component and the second drive component can be flexibly adjusted to adjust the linear speed of the take-up roller and the pressure roller, thereby obtaining film rolls with different tightness. It is not necessary to ensure that the linear speed of the take-up roller and the pressure roller is consistent with the linear speed of the production line equipment.

[0023] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0024] According to some embodiments of this utility model, refer to Figures 1 to 5The slitting edge material winding device includes a frame 100, a winding assembly 200, a pressing assembly 300, and a traction assembly 400. The winding assembly 200 includes a first drive component 210 and a winding roller 220. The winding roller 220 is rotatably connected to the frame 100, and the axis of the winding roller 220 is in the front-to-back direction. The first drive component 210 is mounted on the frame 100 and is used to drive the winding roller 220 to rotate around its own axis. The coiling assembly 300 includes a second drive component 310, a slide block 320, and a coiling roller 330. The axis of the coiling roller 330 is in the front-to-back direction. The slide block 320 is slidably connected to the frame 100 in the up-down direction. The coiling roller 330 is rotatably connected to the slide block 320. The second drive component 310 is mounted on the slide block 320 and is used to drive the coiling roller 330 to rotate around its own axis. The coiling roller 330 is located above the take-up roller 220, and the lower side of the coiling roller 330 can abut against the upper side of the take-up roller 220. The traction assembly 400 includes a traction frame 410, a third drive component 420, a first pressure roller 431, and a second pressure roller 432. The third drive component 420 is mounted on the traction frame 410, which is mounted on the frame 100. Both the first pressure roller 431 and the second pressure roller 432 are rotatably connected to the traction frame 410. The axes of both the first pressure roller 431 and the second pressure roller 432 are in the front-rear direction. The first pressure roller 431 is located below the second pressure roller 432. The third drive component 420 drives the first pressure roller 431 to rotate around its own axis. The lower side of the second pressure roller 432 can abut against the upper side of the take-up roller 220. The first drive component 210, the second drive component 310, and the third drive component 420 are all servo motors. Figure 3 The edge material 110 is shown as a thick solid line.

[0025] During the winding process of the edge material 110, the third drive component 420 drives the first pressure roller 431 to rotate, the first drive component 210 drives the take-up roller 220 to rotate, and the second drive component 310 drives the pressure roller 330 to rotate. The take-up roller 220 and the pressure roller 330 have the same linear velocity but opposite directions. The surface of the take-up roller 220 can be chrome-plated or coated with elastic materials such as polyurethane or rubber to increase friction and protect the surface of the edge material 110 from scratches. The pressure roller 330, by forming a pressure against the take-up roller 220, squeezes air out from between the layers of the edge material 110, making the edge material 110 more tightly and flat, preventing defects such as bulging. The surface of the pressure roller 330 can also be coated with an elastic material. The design of the slide 320 allows the pressure roller 330 to automatically rise as the winding diameter increases, ensuring that the pressure roller 330 is always in contact with the outermost layer of edge material 110. When the edge material 110 enters the gap between the take-up roller 220 and the pressure roller 330, both sides of the edge material 110 are simultaneously driven by the two roller surfaces. This avoids the interlayer slippage and static electricity accumulation problems that may occur if the entire roll is rotated solely by the surface friction of the take-up roller 220. This dual-wheel drive method provides a more stable and reliable winding force, ensuring that the roll is wound evenly and tightly from the inside out.

[0026] When the production line equipment cuts the film roll to produce edge material 110, the first pressure roller 431 and the second pressure roller 432 work together to pull the edge material 110 to the left from the production line equipment. The edge material 110 passes around the pressure roller 330 and then wraps around the take-up roller 220. The take-up roller 220 rotates continuously to take up the edge material 110. The pressure roller 330 continuously applies downward pressure to the take-up roller 220 to ensure that the edge material 110 can be tightly wrapped around the take-up roller 220 and avoid loosening.

[0027] During the winding process, the linear speed of the third drive component 420 is consistent with the production line speed, thereby ensuring that the edge material 110 between the first pressure roller 431 and the production line equipment is always taut, that is, ensuring that the edge material 110 located to the right of the first pressure roller 431 is taut. If this section of edge material 110 is slack, the slitting blade of the production line equipment will encounter an unstable object during cutting, resulting in an uneven cut, burrs, or even uneven width, becoming a stress concentration point, making the edge material 110 extremely prone to breakage during subsequent traction and winding. By precisely controlling the linear speed of the first pressure roller 431 to be synchronized with the production line speed through the third drive component 420, a constant and appropriate back tension is provided for the slitting process, ensuring that the edge material 110 is flat and straight at the moment of cutting, thereby guaranteeing the slitting quality.

[0028] It should be noted that during the process of the production line equipment cutting the film roll to produce edge material 110, the cut edge material 110 is in the form of a long strip and is wound up by the edge material winding device. If the edge material 110 is loose, it will result in the inability to cut the edge material 110 accurately and evenly, that is, the width of the edge material 110 cannot be consistent, that is, the side of the edge material 110 will have uneven gaps and be easily torn. Therefore, in this embodiment, the third drive component 420 controls the linear speed of the first pressure roller 431 to be consistent with the production line speed, thereby ensuring that the edge material 110 on the right side of the first pressure roller 431 is in a taut state, which can ensure that the edge material 110 can be cut evenly and then wound up smoothly. The edge material 110 between the first pressure roller 431 and the take-up roller 220 can be in a taut or loose state. During the process of taking up the edge material 110, the take-up roller 220 can flexibly adjust the first drive component 210 and the second drive component 310, thereby adjusting the linear speed of the take-up roller 220 and the pressure roller 330 to obtain film rolls with different tightness. It is not necessary to ensure that the linear speed of the take-up roller 220 and the pressure roller 330 is consistent with the linear speed of the production line equipment.

[0029] It is also understandable that the area between the first pressure roller 431 and the take-up roller 220 is a tension buffer zone. This area allows the edge material 110 to loosen, and the winding speed can be slightly greater or less than the traction speed. For example, in the initial stage of winding, the winding speed can be slightly higher than the traction speed to create greater winding tension, making the core of the roll tighter. As the roll diameter increases, to prevent excessive internal stress from causing roll deformation, the difference between the winding speed and the traction speed can be gradually reduced. This flexible adjustment allows the device to adapt to the winding process requirements of edge material 110 of different materials and thicknesses, resulting in high-quality edge material 110 rolls.

[0030] According to some embodiments of this utility model, refer to Figure 2 and Figure 3 The traction assembly 400 also includes a first cylinder 440, the drive end of which faces upward and is fixedly connected to the slide 320. During the winding process, as the winding diameter of the edge material 110 increases, the pressure roller 330 and the slide 320 move upward, increasing the distance between the pressure roller 330 and the winding roller 220. The first cylinder 440 continuously applies a downward force to the slide 320, thereby enabling the pressure roller 330 to press down firmly on the edge material 110, ensuring that the pressure roller 330 can press the edge material 110 firmly during the winding process, making it less prone to loosening. As the winding diameter increases, the pressure roller 330 is passively raised. Without external force compensation, the pressure provided solely by the weight of the pressure roller 330 itself may lead to uneven winding pressure. The first cylinder 440 ensures that the contact pressure between the pressure roller 330 and the roll remains constant throughout the winding process, regardless of the roll diameter, by applying a continuous, preset downward pressure to the slide block 320.

[0031] According to some embodiments of this utility model, refer to Figures 1 to 3 The slitting edge material winding device also includes an auxiliary component 500, which includes a swing arm 510 and an auxiliary pressure roller 520. The lower end of the swing arm 510 is located to the left of the pressure roller 330, and the lower end of the swing arm 510 is rotatably connected to the slide block 320. The auxiliary pressure roller 520 is rotatably connected to the swing arm 510. The auxiliary pressure roller 520 can rotate around its own axis. The rotation of the swing arm 510 can drive the auxiliary pressure roller 520 to swing above the pressure roller 330 and make the lower side of the auxiliary pressure roller 520 abut against the pressure roller 330. During the winding process, the upper end of the swing arm 510 swings to the right, thereby driving the auxiliary pressure roller 520 to swing to the right and directly above the pressure roller 330. The edge material 110 passes between the auxiliary pressure roller 520 and the pressure roller 330, and then wraps around the take-up roller 220. The cooperation between the auxiliary pressure roller 520 and the pressure roller 330 can ensure that the edge material 110 is tightly attached to the pressure roller 330 before it is wrapped around the take-up roller 220, thus ensuring the winding quality of the edge material 110.

[0032] Understandably, before the edge material 110 enters between the pressure roller 330 and the take-up roller 220, it passes through the pre-compression zone of the auxiliary pressure roller 520 and the pressure roller 330. This effectively removes air trapped between the edge material 110 and the pressure roller 330, and allows the edge material 110 to adhere to the surface of the pressure roller 330 with a larger wrap angle. The larger wrap angle increases the stability of the edge material 110 on the pressure roller 330, making it less prone to lateral slippage; moreover, it has a pre-compression effect, making the edge material 110 flatter when it enters between the pressure roller 330 and the take-up roller 220, further improving the compactness and end-face neatness of the final coil. The design of the swing arm 510 provides operational convenience. During the initial feeding, the swing arm 510 can be swung to the left so that the auxiliary pressure roller 520 is aligned with the pressure roller 330, making it convenient for the operator to introduce the edge material 110. After feeding is completed, the swing arm 510 is swung to the right to close, so that the auxiliary pressure roller 520 can start working.

[0033] According to some embodiments of this utility model, refer to Figures 1 to 5The traction assembly 400 also includes a second cylinder 600 and a mounting frame 610. The second cylinder 600 is mounted on the traction frame 410 with its drive end facing downwards. The drive end of the second cylinder 600 is fixedly connected to the mounting frame 610, and the second pressure roller 432 is rotatably connected to the mounting frame 610. The second cylinder 600 applies a downward force to the mounting frame 610, thereby causing the second pressure roller 432 to press tightly against the first pressure roller 431, ensuring that the first pressure roller 431 and the second pressure roller 432 can press and transport the edge material 110. The function of the second cylinder 600 is to provide a stable and adjustable clamping force for the traction roller pair. For the first pressure roller 431 and the second pressure roller 432 to achieve slip-free traction of the edge material 110, sufficient pressure must be applied to clamp the edge material 110. This pressure needs to be precisely set according to the thickness, surface smoothness, and production line speed of the edge material 110. Insufficient pressure will cause traction slippage, loss of synchronization with the production line speed, and thus lead to breakage of the edge material 110; excessive pressure may damage the surface of the edge material 110 or even deform it. Operators can adjust the pressure of the second cylinder 600 on the mounting bracket 610 to set the optimal traction clamping force for different production tasks.

[0034] According to some embodiments of this utility model, refer to Figure 2 and Figure 5 The traction frame 410 is slidably connected to the frame 100 in the front-to-back direction. The traction assembly 400 also includes a fourth drive component 620, which is mounted on the frame 100 and is used to drive the traction frame 410 to move in the front-to-back direction. Preferably, the frame 100 is provided with a slide rail extending in the front-to-back direction, and the traction frame 410 is slidably connected to the slide rail by a slider. The fourth drive component 620 is a push rod motor, and the drive end of the fourth drive component 620 is fixedly connected to the traction frame 410; or, the fourth drive component 620 is a servo motor, and the drive end of the fourth drive component 620 is connected to a lead screw. The fourth drive component 620 drives the lead screw to rotate, and the lead screw is rotatably connected to the frame 100. The traction frame 410 is mounted on the lead screw by a lead screw seat.

[0035] Understandably, during the winding process, the fourth drive component 620 drives the traction frame 410 to reciprocate in the front-to-back direction, thereby driving the edge material 110 to reciprocate in the front-to-back direction, causing the edge material 110 to spirally wind around the take-up roller 220. The strip of edge material 110 to be wound is evenly distributed across the entire width of the take-up roller 220, forming a cylindrical roll with a flat end face and a regular shape. The fourth drive component 620 drives the entire traction assembly 400 to make smooth reciprocating motion in the axial direction of the take-up roller 220, ensuring that each layer of edge material 110 is laid close to the previous layer of edge material 110, forming a dense spiral. Compared with a push rod motor, the drive method using a servo motor and ball screw can achieve higher positioning accuracy and smoother reversing.

[0036] According to some embodiments of this utility model, refer to Figure 2 and Figure 5 The traction assembly 400 also includes a roller 630, whose axis is in the front-to-back direction. The roller 630 is rotatably connected to the traction frame 410 and is located below the first pressure roller 431. The traction assembly 400 also includes a first traction wheel 640, which is rotatably connected to the traction frame 410. The first traction wheel 640 is located to the left of the roller 630 and to the right of the pressure roller 330. The first traction wheel 640 has a front-to-back axis and baffles at both ends to prevent the edge material 110 from detaching from the first traction wheel 640. After the first pressure roller 431 and the second pressure roller 432 pull the edge material 110 to the left, the edge material 110 passes sequentially around the roller 630 and the first traction wheel 640, then passes between the auxiliary pressure roller 520 and the pressure roller 330, and is wound up by the take-up roller 220.

[0037] Furthermore, refer to Figure 2 and Figure 4 The traction assembly 400 also includes two first guide rods 650, which are fixedly installed on the traction frame 410. The two first guide rods 650 are spaced apart in the front-to-back direction and are located between the first traction wheel 640 and the roller 630. The edge material 110 is located between the two first guide rods 650. After being guided by the roller 630, the edge material 110 passes between the two first guide rods 650 and is then guided by the first traction wheel 640. The two first guide rods 650 restrict the movement of the edge material 110 in the front-to-back direction, thereby preventing the edge material 110 from deviating.

[0038] According to some embodiments of this utility model, refer to Figures 3 to 5 The traction assembly 400 also includes a swing frame 660, a third cylinder 670, and a second traction wheel 680. The left end of the swing frame 660 is rotatably connected to the traction frame 410. The third cylinder 670 is mounted on the traction frame 410, and its drive end is hinged to the swing frame 660. The second traction wheel 680 is rotatably connected to the swing frame 660 and is located below the roller 630. After the first pressure roller 431 and the second pressure roller 432 pull the edge material 110 to the left, the edge material 110 passes sequentially around the second traction wheel 680, the roller 630, and the first traction wheel 640, then passes between the auxiliary pressure roller 520 and the pressure roller 330, and is wound up by the take-up roller 220. The front and rear ends of the second traction wheel 680 have baffles to prevent the edge material 110 from detaching from the first traction wheel 640.

[0039] Since the edge material 110 passes through the first pressure roller 431 and the second pressure roller 432, and then passes through the second traction wheel 680 and the roller 630 in sequence, the extension and retraction of the drive end of the third cylinder 670 can drive the right end of the swing frame 660 to rotate around the left end of the swing frame 660, thereby changing the distance between the second traction wheel 680 and the first pressure roller 431, thus tightening or loosening the edge material 110 between the first pressure roller 431 and the second traction wheel 680.

[0040] Furthermore, refer to Figure 4 and Figure 5 The traction assembly 400 also includes two second guide rods 690, which are fixedly installed on the traction frame 410. The two second guide rods 690 are spaced apart in the front-to-back direction and are located between the second traction wheel 680 and the first pressure roller 431. The edge material 110 is located between the two second guide rods 690, which restrict the movement of the edge material 110 in the front-to-back direction to prevent the edge material 110 from deviating. After passing the first pressure roller 431 and the second pressure roller 432, the edge material 110 passes through the two second guide rods 690 and then passes the second traction wheel 680.

[0041] In this embodiment, the first pressure roller 431 and the second pressure roller 432 jointly pull the edge material 110. The edge material 110 passes between the two second guide rods 690, the second traction wheel 680, the roller 630, between the two first guide rods 650, the first traction wheel 640, and then passes through the auxiliary pressure roller 520 and the coiling roller 330 to be initially compressed. It is then further compressed between the coiling roller 330 and the take-up roller 220 and finally wound onto the take-up roller.

[0042] The working process of this embodiment includes: First, the clamping force of the traction roller pair is set by adjusting the pressure of the second cylinder 600; the contact pressure of the coiling roller 330 on the material roll is set by adjusting the pressure of the first cylinder 440; and the reference tension of the tension buffer swing roller is set by adjusting the pressure of the third cylinder 670.

[0043] At the start of the operation, the production line slitting blade cuts off the edge material 110, and the operator manually passes the edge material 110 head through the entire device. The edge material 110 first enters the traction port composed of the first pressure roller 431 and the second pressure roller 432. The second cylinder 600 drives the second pressure roller 432 to press against the first pressure roller 431, reliably clamping the edge material 110. The third drive component 420 starts, and the linear speed of the third drive component 420, which is completely synchronized with the main production line machine, drives the first pressure roller 431 to rotate, stably pulling the edge material 110 out of the slitting station, and ensuring that the edge material 110 between the slitting point and the traction port has a constant tension, thus ensuring the slitting quality.

[0044] The drawn edge material 110 then passes between the two second guide rods 690, its lateral position being initially precisely defined. Next, the edge material 110 passes over the second traction wheel 680 mounted on the swing frame 660, which, under the action of the third cylinder 670, dynamically buffers and stabilizes the tension of the edge material 110. Subsequently, the edge material 110 travels upwards, passes over the roller 630, changes its direction of travel, and passes between the two first guide rods 650, its lateral position being precisely calibrated again. Afterwards, the edge material 110 passes over the first traction wheel 640 with a baffle, receiving final path guidance and lateral protection before entering the take-up core area. Simultaneously, the fourth drive unit 620 drives the entire traction frame 410 to smoothly reciprocate along the axial direction of the take-up roller 220, achieving the wire laying function.

[0045] After precise guidance and tension stabilization, the edge material 110 enters the winding area. The edge material 110 first passes through the pre-compression zone formed by the auxiliary pressure roller 520 and the pressure roller 330, expelling air and initially adhering to the surface. Next, the edge material 110 enters the main pressure zone formed by the pressure roller 330 and the take-up roller 220, where it is tightly compacted under the constant pressure applied by the first cylinder 440. The first drive component 210 and the second drive component 310 work together to drive the take-up roller 220 and the pressure roller 330 to rotate, adjusting the speed in real time to achieve precise tension control during winding. As winding progresses, the diameter of the material roll on the take-up roller 220 continuously increases, while the pressure roller 330 and the slide 320 rise smoothly under the push of the material roll, while the first cylinder 440 maintains downward pressure to ensure winding quality.
