Description

Technical Field

[0001] This invention relates to the field of composite film processing technology, and in particular to a composite film coating machine winding system. Background Technology

[0002] Coating and laminating equipment is mainly used for the coating and lamination of various roll substrates such as plastic film, paper, electroplated aluminum, fabric, and leather. It is widely used in various packaging fields and has broad development prospects. Coating and laminating equipment is generally divided into three types: smooth roller coating, anilox roller coating, and hot melt adhesive spraying and extrusion coating. The winding machine is the receiving part of the roll material processing production line, a machine that mechanically winds raw materials into rolls. In daily life, it is widely used in paper rolls, fabric rolls, plastic rolls, and metal roll processing production lines. It is powered by a variable frequency motor and is an active winding machine. Through the winding machine and tensioner (or rolling mill), high tension can be provided to the winding section. It can be divided into upper winding and lower winding.

[0003] Existing winding systems often only have a slight shrinkage effect to facilitate material handling, but they cannot adapt to the processing of winding materials with different core diameters. At this time, winding rollers of different diameters and sizes are required to meet the requirements, resulting in high material costs and complicated replacement operations. In addition, the limit baffles at both ends of the winding rollers also need to be replaced to adapt to winding rollers of different diameters, which is complicated to operate and has a limited range of applicability. Summary of the Invention

[0004] The purpose of this invention is to provide a winding system for a composite film coating machine. This invention incorporates a winding frame that can automatically shrink and is equipped with a material-stopping device that can adapt to winding frames of different diameters.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a composite film coating machine winding system, comprising two parallel frames and a winding frame body disposed inside the two frames. The winding frame body includes a plurality of support rods, a telescopic sleeve, a push rod one, and a push rod two. The telescopic sleeve is movably sleeved on the support rods. Fixed sleeves are fixedly sleeved at the ends of the plurality of support rods. Push rod one and push rod two are rotatably connected in a cross manner. The two ends of push rod one are rotatably connected to the telescopic sleeves and the fixed sleeves on two adjacent support rods, respectively. The two ends of push rod two are rotatably connected to the telescopic sleeves and the fixed sleeves on two adjacent support rods, respectively. A horizontal threaded rod is threadedly connected to the telescopic sleeve on one of the support rods. The two ends of the support rod are fixedly connected to the frame. The threaded rod of the horizontal threaded rod is parallel to the support rod. A drive motor is provided on the frame, and the drive motor drives the threaded rod of the horizontal threaded rod to rotate.

[0006] A further configuration of the present invention includes: a vertical threaded rod connected between the fixed sleeves at the ends of the upper and lower support rods; both ends of the vertical threaded rod are rotatably connected within the fixed sleeves; a horizontal bevel gear is mounted on the vertical threaded rod, and a vertical bevel gear is mounted on the horizontal threaded rod, the vertical bevel gear meshing with the horizontal bevel gear; a drive motor is provided with a drive rod, the end of which is provided with a drive bevel gear meshing with the horizontal bevel gear; a support block is threadedly connected to the vertical threaded rod; two guide rods are slidably connected parallel to both sides of the support block, the ends of which are connected to the fixed sleeves; the drive motor controls the rotation of the vertical threaded rod to move the support block, ensuring that the support block remains on the axis of the winding frame; a rotating rod is connected between the two support blocks, the rotating rod being located on the axis of the winding frame; a rotating motor is mounted at the end of the rotating rod, the rotating motor driving the support block to rotate the winding frame.

[0007] A further embodiment of the present invention is provided with a material-blocking mechanism on the support block. The material-blocking mechanism includes a guide frame, a telescopic arm, a material-blocking plate, and a driving member for driving the telescopic arm to move, all radially fixedly connected to the support block. The material-blocking plate is fixedly connected to the outside of the telescopic arm. The telescopic arm includes an axial plate axially connected to the end of the telescopic arm and a baffle plate vertically connected to the end of the axial plate. The guide frame is provided with a plurality of sliding grooves. The telescopic arm is slidably connected to the sliding grooves on the guide frame. The driving member drives the telescopic arm to move radially along the sliding grooves.

[0008] A further configuration of the present invention is as follows: the driving component includes a driving gear; the rotating rod passes through the support block and is movably inserted into the frame; the driving gear is rotatably connected to the rotating rod; a vertical rack is provided on the frame, the vertical rack meshes with the outer side of the gear; a control rod is provided on the side of the telescopic arm away from the baffle plate; the driving gear has radially arranged strip-shaped holes, the strip-shaped holes are arc-shaped, and the control rod on the telescopic arm is movably inserted into the strip-shaped holes.

[0009] A further configuration of the present invention is as follows: movable slots are arranged parallel to each other on the frame on both sides; movable blocks are rotatably connected to both ends of the rotating rod; the rotating motor is fixedly connected to one end of the rotating rod; and the movable blocks are slidably connected in the movable slots on the frame.

[0010] The beneficial effects of this invention are:

[0011] 1. The winding frame in this invention has an automatic telescopic effect, which can first meet the winding of composite films with different winding thicknesses, and at the same time, it can facilitate the unloading of composite films after winding. The shrinking of the winding frame makes it easier to remove the composite film roll that is tightly stretched on the winding frame. In addition, this invention also incorporates a material blocking device that can adapt to winding frames with different diameters, in conjunction with the automatically shrinking winding frame.

[0012] 2. In this invention, the winding frame is driven by a motor to rotate a horizontal threaded rod. This horizontal threaded rod drives the telescopic sleeve on one of the support rods to move. Further, push rods one and two, connected between the telescopic sleeve and the fixed sleeve, cause several support rods to contract synchronously, achieving the contraction and expansion of the winding frame. Since the position of one support rod is fixed in this invention, the axis of the entire winding frame moves during the movement of the other support rods. Therefore, six support rods are provided, with a vertical threaded rod rotatably connecting two opposing support rods. A support block is threaded onto the vertical threaded rod, and the vertical threaded rod and the horizontal threaded rod are meshed through a bevel gear. This allows the vertical threaded rod to rotate while the horizontal threaded rod moves to adjust the winding frame. The support block remains on the axis of the winding frame, enabling it to move synchronously with the winding frame and remain centered. The support blocks at both ends are connected by a rotating rod, and a rotating motor is connected to the end of the connecting rod. As the rotating motor drives the rotating rod to rotate, it drives the entire winding frame to rotate through the support blocks, thus achieving the winding or unfolding of the composite film.

[0013] 3. This invention includes a material-stopping mechanism, which is mounted on the support block. Therefore, the material-stopping mechanism is coaxially arranged with the winding frame. Simultaneously, the vertical rack is fixed to the frame. During the upward movement of the drive gear driven by the support block, the upward movement of the drive gear causes it to rotate. As the drive gear rotates, it drives the telescopic arm to extend outward along the sliding groove through the strip-shaped hole, allowing the material-stopping plate to expand to a larger radius and thus a larger diameter to be wound. This is because when the winding frame expands its diameter, the corresponding telescopic arm also needs to expand to prevent the material-stopping arm from blocking the winding of the thicker composite film, thus limiting the winding process and preventing unevenness at both ends of the composite film during winding.

[0023] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0024] Examples, such as Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a composite film coating machine winding system includes two parallel frames and a winding frame body disposed inside the two frames. The winding frame body 2 includes several support rods 21, a telescopic sleeve 22, a push rod 1 23, and a push rod 24. The telescopic sleeve 22 is movably sleeved on the support rods 21. Fixed sleeves 211 are fixedly sleeved on the ends of the support rods 21. The push rod 1 23 and the push rod 24 are rotatably connected. The two ends of the push rod 1 23 are respectively rotatably connected to the telescopic sleeves on two adjacent support rods 21. On the fixed sleeve 211, the two ends of the push rod 24 are rotatably connected to the telescopic sleeve 22 on the two adjacent support rods 21 and the fixed sleeve 211, respectively. A horizontal threaded rod 25 is threadedly connected to the telescopic sleeve 22 on one of the support rods 21. The two ends of the support rod 21 are fixedly connected to the frame 1. The threaded rod of the horizontal threaded rod 25 is parallel to the support rod 21. A drive motor 26 is provided on the frame 1. The drive motor 26 drives the threaded rod of the horizontal threaded rod 25 to rotate.

[0025] The winding frame 2 in this invention has an automatic telescopic effect. First, it can meet the winding of composite films with different winding thicknesses. At the same time, it can also facilitate the unloading of composite films after winding. The shrinking of the winding frame 2 makes it easier to remove the composite film roll that is tightly stretched on the winding frame 2. In addition, this invention also incorporates a material blocking device that can adapt to winding frame 2s with different diameters, in conjunction with the automatically shrinking winding frame 2.

[0026] like Figure 4 , Figure 5As shown, a further configuration of the present invention is as follows: a vertical threaded rod 27 is provided between the fixing sleeves 211 at the ends of the upper and lower support rods 21, and the two ends of the vertical threaded rod 27 are rotatably connected inside the fixing sleeves 211. A horizontal bevel gear 271 is provided on the vertical threaded rod 27, and a vertical bevel gear 251 is provided on the horizontal threaded rod 25. The vertical bevel gear 251 meshes with the horizontal bevel gear 271. The drive motor 26 is provided with a drive rod 261, and a drive bevel gear 262 is provided at the end of the drive rod 261. The drive bevel gear 262 meshes with the horizontal bevel gear 271. A support block 28 is threaded onto a straight threaded rod 27. Two guide rods 281 are slidably connected to both sides of the support block 28. The two ends of the guide rods 281 are connected to the fixed sleeve 211. The drive motor 26 controls the vertical threaded rod 27 to rotate, thereby moving the support block 28 so that the support block 28 is always located on the axis of the winding frame 2. A rotating rod 29 is connected between the two support blocks 28. The rotating rod 29 is located on the axis of the winding frame 2. A rotating motor 291 is provided at the end of the rotating rod 29. The rotating motor 291 drives the support block 28 to rotate the winding frame 2.

[0027] In this invention, the winding frame 2 is driven by a drive motor 26 to rotate a horizontal threaded rod 25. The horizontal threaded rod 25 drives the telescopic sleeve 22 on one of the support rods 21 to move. Further, push rods 23 and 24, connected between the telescopic sleeve 22 and the fixed sleeve 211, cause several support rods 21 to contract synchronously, thus achieving the contraction and expansion of the winding frame 2. Since the position of one support rod 21 is fixed in this invention, the axis of the entire winding frame 2 moves during the movement of the other support rods 21. Therefore, six support rods 21 are provided, with a vertical threaded rod 27 rotatably connecting two opposing support rods 21. A support block 28 is threaded onto the vertical threaded rod 27, and the vertical threaded rod 27 and the horizontal threaded rod 25 are meshed through a bevel gear. When the horizontal threaded rod 25 moves to adjust the winding frame 2, the vertical threaded rod 27 will also rotate. At the same time, the support block 28 is kept on the axis of the winding frame 2, so that the support block 28 can move synchronously with the winding frame 2 and always stay on its axis. The support blocks 28 at both ends are connected by a rotating rod 29, and a rotating motor 291 is connected to the end of the connecting rod. When the rotating motor 291 drives the rotating rod 29 to rotate, it can drive the entire winding frame 2 to rotate through the support block 28, so as to realize the winding or unfolding of the composite film.

[0028] like Figure 5 , Figure 6 , Figure 7As shown, a further configuration of the present invention is as follows: a material blocking mechanism 3 is provided on the support block 28. The material blocking mechanism 3 includes a guide frame 31, a telescopic arm 32, a baffle plate 33, and a driving member for driving the telescopic arm 32 to move, which are radially fixedly connected to the support block 28. The baffle plate 33 is fixedly connected to the outside of the telescopic arm 32. The telescopic arm 32 includes an axial plate 331 axially connected to the end of the telescopic arm 32 and a baffle plate 332 vertically connected to the end of the axial plate 331. A plurality of sliding grooves 311 are provided on the guide frame 31. The telescopic arm 32 is slidably connected to the sliding grooves 311 on the guide frame 31. The driving member drives the telescopic arm 32 to move radially along the sliding grooves 311.

[0029] like Figure 7 As shown, a further configuration of the present invention is as follows: the driving component includes a driving gear 34; the rotating rod 29 passes through the support block 28 and is movably inserted into the frame 1; the driving gear 34 is rotatably connected to the rotating rod 29; a vertical rack 35 is provided on the frame 1; the vertical rack 35 meshes with the outer side of the gear; a control rod 321 is provided on the side of the telescopic arm 32 away from the baffle plate 33; a strip-shaped hole 341 is radially provided on the driving gear 34; the strip-shaped hole 341 is arc-shaped; and the control rod 321 on the telescopic arm 32 is movably inserted into the strip-shaped hole 341.

[0030] like Figure 7 As shown, a further configuration of the present invention is as follows: movable slots 11 are arranged in parallel on both sides of the frame 1; movable blocks 12 are rotatably connected to both ends of the rotating rod 29; the rotating motor 291 is fixedly connected to one end of the rotating rod 29; and the movable blocks 12 are slidably connected in the movable slots 11 on the frame 1.

[0031] The present invention includes a material-stopping mechanism 3, which is mounted on the support block 28. Therefore, the material-stopping mechanism 3 is coaxially mounted with the winding frame 2. Meanwhile, the vertical rack 35 is fixed on the frame 1. During the upward movement of the drive gear 34 driven by the support block 28, the upward movement of the drive gear 34 will cause the drive gear 34 to rotate. During the rotation of the drive gear 34, the telescopic arm 32 will be driven to expand outward along the sliding groove 311 through the strip hole 341, so that the material-stopping plate 33 can expand to a larger radius and the diameter to be wound is larger. This is because when the winding frame 2 expands its diameter, the corresponding telescopic arm 32 also needs to expand so that the material-stopping arm can block the winding of the thicker composite film, thus playing a role in winding limit and avoiding the problem of uneven ends during the winding of the composite film.
