Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of packaging material rolling, and in particular to a rolling device with a flattening structure and a use method thereof. Background Art
[0002] In modern industrial production, efficient and high-quality winding and packaging of packaging materials such as films and paper is a key step to ensure the subsequent storage, transportation and use of products. With the development of automation technology, the winding process of packaging materials has gradually turned to automation and intelligence to improve production efficiency, reduce production costs and improve product quality.
[0003] As the back-end equipment for packaging material processing, the core function of the winding device is to wind the material into a roll by mechanical means for subsequent storage, transportation and use. The traditional winding device is usually equipped with key components such as a winding shaft, a winding roller, a tensioning device and an adjustment device. The winding shaft serves as a driving mechanism and is driven by a motor or a hydraulic system to achieve uniform and continuous winding of the material. The winding roller ensures the stability and tension control of the material during the winding process. The tensioning device ensures the appropriate tension of the material during the winding process. The adjustment device allows the operator to make precise adjustments according to different material width, thickness and other parameters to meet the needs of different application scenarios.
[0004] In the process of winding packaging materials, curved rollers are usually used to flatten the materials. The curved rollers move in the opposite direction to the materials. During the rotation, the curvature of the curved rollers applies pressure in the width direction of the materials, thereby reducing the wrinkles generated in the winding process. However, in the prior art: During the manufacturing process, the arc roller is set to a certain curvature. When this curved roller rotates, its curvature setting allows only one side of the roller to contact the material. Each time the roller rotates one circle, only one side of the roller surface is actually in contact with the material, thereby exerting pressure. This means that in a complete rotation cycle of the roller, only half of the surface effectively exerts pressure on the material. When it comes to film materials and paper with a certain thickness, since thicker materials usually have a certain rigidity, the unidirectionally set arc roller cannot exert enough pressure on them, which results in the material still retaining a certain degree of wrinkles and corrugation defects when it is wound. At present, in order to improve the flattening effect of the arc roller on the material, the number of rotations is usually increased during the winding process so that the material is fully processed. However, during high-speed winding, the arc roller may reach a resonance point, thereby causing the equipment to vibrate, which not only affects the stability of the winding, but also shortens the service life of the equipment. Therefore, a winding device with a flattening structure and a method for using the same are needed to solve the above problems. Summary of the invention

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0022] Reference Figure 1-3 , a winding device with a flattening structure, comprising a frame 1 and a winding assembly 2 and a coiling assembly 3 arranged on the frame 1, and a guide assembly 4 is also arranged on the frame 1; The guide assembly 4 includes a hollow roller 41 rotatably arranged on the frame 1, and three groups of receiving grooves 411 are equidistantly provided on the hollow roller 41 along the circumferential direction. A mechanism 5 for applying pressure to the material and flattening the material is provided in the receiving groove 411. The flattening mechanism 5 includes three groups of arc plates 51, and each group of arc plates 51 is rotatably arranged in the corresponding receiving groove 411 through an axle rod 52. Both ends of each group of axle rod 52 are provided with torsion springs 53, and the two ends of each group of torsion springs 53 are respectively fixed in the corresponding receiving groove 411 and on the arc plate 51. When the three groups of arc plates 51 are located in the corresponding receiving grooves 411, they can be in a retracted state under the torsion force of the torsion springs 53. At this time, the three groups of arc plates 51 and the hollow roller 41 can form a flat roller for use.
[0023] The guide assembly 4 also includes a rotating shaft 42 fixed to the left end of the hollow roller 41 and a gear 1 43 fixed on the rotating shaft 42. The rotating shaft 42 is rotatably connected to the left side of the frame 1. A motor 8 is installed on the frame 1. A gear 2 9 is fixed to the output end of the motor 8. The gear 2 9 is meshed with the gear 1 43. When the motor 8 controls the gear 2 9 to rotate counterclockwise, the gear 1 43 controls the hollow roller 41 to rotate clockwise through the meshing action of the gear 2 9 and the gear 1 43.
[0024] During use: when the starting motor 8 controls gear 2 9 to rotate counterclockwise, the meshing action of gear 2 9 and gear 1 43 makes gear 1 43 control the hollow roller 41 to rotate clockwise. At this time, the hollow roller 41 drives the arc plate 51 to rotate. The material is guided by the winding component 2 and conveyed from front to back through the surface of the hollow roller 41. At this time, the rotation direction of the arc plate 51 is opposite to the conveying direction of the material, so that appropriate force can be applied to the surface of the sheet to keep the packaging material flat during the winding process, avoiding quality problems caused by excessive or uneven tension.
[0025] Reference Figure 4-8The hollow roller 41 is provided with an adjustment mechanism 6 for controlling the unfolding or folding of the three groups of arc-shaped plates 51. The adjustment mechanism 6 includes an adjustment wheel 61 rotatably arranged in the hollow roller 41, three groups of arc-shaped guide rails 62 arranged at the left end of the adjustment wheel 61, a connecting rod 63 slidably arranged in each group of arc-shaped guide rails 62, a support plate 64 rotatably connected to each group of connecting rods 63 through a rotating shaft, a movable groove 65 arranged in the adjustment wheel 61, two groups of vertical plates 66 fixed in the movable groove 65, and a long plate 67 arranged between the two groups of vertical plates 66, wherein each group of support plates 64 is connected to the end of the arc-shaped guide rail 62 away from the connecting rod 63 through a rotating shaft. Rotating connection, each group of support plates 64 is limited in the corresponding storage groove 411 and contacts the inner side of the arc plate 51. The three groups of support plates 64 are controlled to move outward by rotating the adjusting wheel 61, and the three groups of arc plates 51 can be controlled to flip outward at the same time. When facing thicker packaging materials, the three groups of arc plates 51 can adjust the angle according to the thickness of the material to enhance the local pressure on the material, and the three groups of arc plates 51 are used in combination. When the hollow roller 41 completes a complete rotation cycle, the three groups of arc plates 51 can pressurize the material in turn, thereby forming a uniform contact pressure on the surface of the material and improving the flattening effect.
[0026] Reference Figure 9-11 The right end of the hollow roller 41 is provided with a rotating mechanism 7, which includes a gripping rod 71 rotatably arranged on the right side of the frame 1, a disc 72 fixed on the gripping rod 71, an inserting rod 73 fixed on the disc 72, a docking rod 74 limitedly inserted in the gripping rod 71, a spring 75 arranged between the docking rod 74 and the gripping rod 71, a fixed disk 76 fixedly connected to the docking rod 74, a connecting block 1 77 arranged on the fixed disk 76, a connecting rod 78 fixed on the connecting block 1 77, and a connecting block 2 79 fixedly connected to the connecting rod 78, wherein the connecting block 2 79 is fixed to the long plate 67, wherein the right end of the adjusting wheel 61 is provided with a There is a second guide groove 612 for the long plate 67 to move up and down through. The long plate 67 passes through the second guide groove 612 and is fixed to the second connecting block 79. The second connecting block 79 is located at the center of the right end of the adjusting wheel 61. When the handle 71 is controlled to rotate, the disc 72, the fixed disc 76, the first connecting block 77, the connecting rod 78 and the second connecting block 79 can be controlled to rotate at the same time. When the second connecting block 79 rotates, the long plate 67 can be controlled to rotate. By limiting the position of the vertical plate 66, the long plate 67 can drive the adjusting wheel 61 as a whole to rotate around the second connecting block 79 as the center, thereby controlling the three groups of arc plates 51 to be unfolded or retracted. Please refer to Fig.12 A rotating hole 111 is provided on the right inner wall of the frame 1, and a rotating block 112 is rotatably connected in the rotating hole 111. The gripping rod 71 and the rotating block 112 are connected via a spline shaft, so that the gripping rod 71 can be pulled outward and rotated easily.
[0027] Please refer to Fig. 9The inner wall of the right end of the hollow roller 41 is provided with a guide groove 412 for the connecting rod 78 to movably pass through, the connecting block 79 is movably fitted to the inner side of the guide groove 412, and the connecting block 77 is movably fitted to the outer side of the guide groove 412, wherein the length of the guide groove 412 is adapted to the length of the guide groove 612.
[0028] Please refer to Fig. 9 The inner wall of the right end of the hollow roller 41 is provided with a plurality of slots 413 for inserting the inserting rods 73. Two groups of the inserting rods 73 are symmetrically provided. The ends of the two groups of the inserting rods 73 away from the disc 72 respectively penetrate the fixed disc 76 and are inserted into the corresponding slots 413 to fix the gripping rod 71 and the hollow roller 41. By fixing the gripping rod 71, the gripping rod 71 can be prevented from rotating, thereby improving the stability of the curved plate 51. Please refer to Figure 10-11 Four groups of limit blocks 741 are symmetrically fixed on the docking rod 74, and a slide groove 711 is provided in the gripping rod 71 for the limit blocks 741 to slide in a limited manner. When the gripping rod 71 rotates, the limit blocks 741 and the slide groove 711 cooperate with each other, which can not only facilitate the synchronous rotation of the docking rod 74, but also enable the gripping rod 71 and the docking rod 74 to be limited and extended.
[0029] When the locking cam 73 is in the unlocking state, the locking cam 73 is in the unlocking state, and the locking cam 73 is in the unlocking state, so that the locking cam 73 is locked. The whole body rotates with the connecting block 2 79 as the center point. When the adjusting wheel 61 rotates, the connecting rod 63 slides in the arc guide rail 62. At this time, the storage groove 411 is used to limit the support plate 1 64, so that the support plate 1 64 moves outward and applies force to the arc plate 51. After the arc plate 51 receives the thrust from the support plate 1 64, it rotates and unfolds with the shaft 52 as the center. At this time, the three groups of arc plates 51 are turned outward at the same time, and the support plate 1 64 can contact the inner side of the arc plate 51 under the action of the rotating shaft. When the arc plate 51 is turned to a suitable angle, the gripping rod 71 is released again, and the elastic force of the spring 75 is used to control the gripping rod 71 to retract. At this time, the insertion rod 73 is inserted into the corresponding slot 413 again to fix the gripping rod 71 and the hollow roller 41.
[0030] Further, see Figure 13-14The adjustment mechanism 6 also includes a movable plate 68 arranged on a central axis with the long plate 67 and a supporting plate 2 69 rotatably connected to the movable plate 68 through a rotating shaft. A limiting groove 611 for limiting the movable plate 68 and the supporting plate 2 69 is provided in the adjusting wheel 61. The supporting plate 2 69 corresponds to one group of supporting plates 1 64. A through groove 641 adapted to the supporting plate 2 69 is provided on one group of supporting plates 1 64. The supporting plate 2 69 is controlled to move outward by the long plate 67, so that the supporting plate 2 69 can pass through the through groove 641 and contact with a group of arc plates 51, and control it to flip outward alone. By controlling the three groups of arc plates 51 to unfold simultaneously or individually, it can be suitable for materials of different thicknesses.
[0031] Specifically, a cavity 761 is provided in the fixed disk 76, and a screw rod 762 is rotatably connected in the cavity 761. A handle 763 is fixed on the top of the screw rod 762. A sleeve block 764 is sleeved on the external thread of the screw rod 762. A slider 765 is fixed on the sleeve block 764. The slider 765 is fixedly connected to the connecting block 1 77. A slide rail cooperating with the slider 765 is provided on the fixed disk 76. Rotating the screw rod 762 can control the movement of the connecting block 2 79. The upward movement of the connecting block 2 79 can control the movement of the long plate 67 and push the movable plate 68, so that the support plate 2 69 passes through the through slot 641 and contacts with a group of arc plates 51, and controls them to flip outward separately.
[0032] During use: when it is necessary to control a group of arc plates 51 to unfold, by holding the rotary handle 763 and rotating the rotary handle 763, the screw rod 762 rotates, and the limiting effect of the slider 765 is used to make the sleeve block 764 drive the connecting block 1 77, the connecting rod 78 and the connecting block 2 79 to move upward. At this time, the connecting block 2 79 moves in the guide groove 1 412 and controls the long plate 67 to move in the guide groove 2 612. At this time, the long plate 67 moves upward between the two groups of vertical plates 66 and pushes the movable plate 68. At this time, the movable plate 68 and support plate 2 69 move in the limiting groove 611, and support plate 2 69 passes through the through groove 641 and contacts the inner side of the corresponding group of arc plates 51. After receiving the thrust from support plate 1 64, the group of arc plates 51 corresponding to support plate 2 69 rotates and unfolds around the shaft 52, and support plate 2 69 can contact the inner side of the corresponding group of arc plates 51 under the action of the rotating shaft. When it is flipped to a suitable angle, stop rotating the knob 763, and the position of the unfolded arc plates 51 can be fixed.
[0033] The present invention provides a method for using a winding device with a flattening structure, which is applied to the winding device with a flattening structure and comprises the following steps: S1. When the three sets of arc plates 51 need to be controlled to unfold, hold the handle 71 and move it outward to release the fixation between the handle 71 and the hollow roller 41, and then rotate the handle 71 to control the disc 72, the fixed disc 76, the connecting block 1 77, the connecting rod 78, the connecting block 2 79 and the long plate 67 to rotate simultaneously; S2. When the long plate 67 rotates, the adjustment wheel 61 is driven to rotate as a whole through the limit of the vertical plate 66. When the adjustment wheel 61 rotates, the connecting rod 63 slides in the arc guide rail 62 and controls the support plate 1 64 to move outward to apply force to the arc plate 51. S3, after receiving the thrust from the support plate 1 64, the arc plate 51 rotates and unfolds around the shaft 52, and at this time, the three sets of arc plates 51 flip outward at the same time; S4, after the arc plate 51 is turned to a suitable angle, the gripping rod 71 is released, the elastic force of the spring 75 is used to control the gripping rod 71 to retract, and the gripping rod 71 and the hollow roller 41 are fixed again by the insertion rod 73; S5. When it is necessary to control a group of arc-shaped plates 51 to unfold, hold the handle 763 and turn it. As the screw rod 762 rotates, the sleeve block 764 drives the connecting block 1 77, the connecting rod 78, the connecting block 2 79 and the long plate 67 to move upward; S6. Using the thrust of the long plate 67 on the movable plate 68, the movable plate 68 controls the second support plate 69 to move outward and applies force to a group of arc plates 51. After receiving the thrust of the second support plate 69, the group of arc plates 51 flips outward.
