Description

Technical Field

[0001] This utility model relates to the field of coating composite roll production technology, and more specifically to a quick roll-changing coating composite production line device. Background Technology

[0002] In a laminating production line, the laminating machine is a key piece of equipment, mainly used to laminate laminating materials with other roll materials. The laminating machine heats the laminating material (such as plastic film) to a molten state and then evenly coats it onto the surface of another roll substrate (such as paper, non-woven fabric, aluminum foil, etc.). While the two are bonded together, they are cooled and cured, so that the laminating material and the substrate are firmly bonded together to form a composite material with specific properties. The winding device in the equipment is mainly used to wind up the laminated roll to form the finished roll.

[0003] A search revealed that utility model patent CN217732170U discloses a high-efficiency winding device for an extrusion casting laminator and a coating machine, comprising a support frame and a winding roller. The fixed rod has swing plates that pass through and rotatably connect to both ends of its outer diameter. The winding roller is rotatably connected between the two bearing seats. A pressing block passes through and rotatably connects to both rotating seats. A pressing shaft passes through and rotatably connects to the two fixed seats.

[0004] However, the roll changing operation in this patented and existing laminating machines is quite cumbersome, requiring manual adjustment and fixation of multiple components. For example, for a specific roll size, the corresponding roll roller needs to be replaced, or the roll is fitted onto the rotating roller and then clamped on both sides to fix it to the roller. Therefore, the existing technology takes a long time to change rolls, affecting production efficiency. As a result, it lacks flexibility in fixing the roll and is difficult to adapt to rolls of different sizes. During the winding process, the roll may not be securely fixed, resulting in uneven winding of the roll material and affecting the quality of the finished product. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a quick roll-changing coating and laminating production line device to solve the problems existing in the background art.

[0006] The utility model provides the following technical solution: a quick roll-changing coating and laminating production line device, comprising a winding equipment body and a drive rod rotatably connected by a drive motor, a fixed shaft being fixedly connected through the inside of the drive rod, a rotating roller being rotatably connected to the outer surface of the fixed shaft, a positioning component being installed inside the rotating roller, and sealing grooves communicating with the output end of the positioning component being equidistantly opened inside the rotating roller, a sealing plate being slidably connected inside the sealing groove, a stop plate being fixedly connected to the surface of the sealing plate, a connecting rod being fixedly connected to the end face of the rotating roller, and a fixing component being installed at the connection between the connecting rod and the winding equipment body.

[0007] Furthermore, the positioning component includes a sealing cavity and a communicating groove inside the roller. The interior of the sealing cavity is connected to the interior of the sealing groove through the communicating groove. A sealing disc is slidably connected inside the sealing cavity. A spring is fixedly connected to the surface of the sealing disc. A steel wire rope is fixedly connected to the center of the surface of the sealing disc. An elongated groove is opened inside the roller. The end face of the steel wire rope away from the sealing disc is fixedly connected to the surface of the drive rod.

[0008] Furthermore, the surface of the abutment away from the sealing plate extends to the outer surface of the rotating roller. Under normal conditions, the elasticity of the spring causes the sealing disc to slide away from the drive rod, and the interior of the sealing groove is under high pressure.

[0009] Furthermore, a bearing is installed at the connection between the fixed shaft and the rotating roller. The fixed shaft is rotatably connected to the inside of the rotating roller through the bearing. A limit ring is fixedly sleeved on the outer surface of the rotating roller. The outer surface of the wire rope is slidably connected to the inside of the long groove. A groove is opened on the surface of the rotating roller near the drive rod. The outer surface of the drive rod is rotatably connected to the inside of the groove.

[0010] Furthermore, the fixing component includes a fixing seat fixedly connected to the surface of the main body of the winding equipment. An arc-shaped plate is rotatably connected to the surface of the fixing seat, and a fixing pin is fixedly connected to the surface of the fixing seat. A hydraulic cylinder is rotatably connected to the outer surface of the fixing pin. The output end of the hydraulic cylinder is rotatably connected to the surface of the arc-shaped plate through a pin shaft. A slot is opened on the surface of the fixing seat, and a retaining ring is fixedly connected inside the slot.

[0011] Furthermore, steel balls are equidistantly installed at the connection points between the retaining ring and the connecting rod, and between the arc-shaped plate and the connecting rod. The surface of the arc-shaped plate near the connecting rod is arc-shaped, and the connecting rod is rotatably connected inside the slot.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model achieves rapid roll changing by utilizing the coordinated operation of a fixing component and a positioning component. During operation, a hydraulic cylinder controls the rotation of an arc-shaped plate, facilitating the separation and installation of connecting rods. The rotation of the rotating roller, in conjunction with the adjustment of the sealing structure, enables the rapid connection and fixation of a new roll, greatly reducing roll changing time, increasing the effective production time of the equipment, and thus improving overall production efficiency.

[0014] 2. In this utility model, the design of the steel balls and arc plate in the fixing component reduces the rotational friction of the connecting rod and enhances the connection stability; the positioning component firmly fixes the drum, preventing the drum from shaking or slipping during winding, effectively preventing problems such as wrinkles and deviation of the roll material, ensuring a smooth winding process, improving the quality of the finished roll material, and enhancing the product's market competitiveness.

[0020] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0021] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0022] A rapid roll-changing coating and laminating production line device includes a winding equipment body 1 and a drive rod 2 rotatably connected by a drive motor. A fixed shaft 3 is fixedly connected through the inside of the drive rod 2. A rotating roller 5 is rotatably connected to the outer surface of the fixed shaft 3. A positioning component 7 is installed inside the rotating roller 5. Sealing grooves 8, which are connected to the output end of the positioning component 7, are equidistantly opened inside the rotating roller 5. A sealing plate 9 is slidably connected inside the sealing groove 8. A stop plate 10 is fixedly connected to the surface of the sealing plate 9. A connecting rod 201 is fixedly connected to the end face of the rotating roller 5. A fixing component 11 is installed at the connection between the connecting rod 201 and the winding equipment body 1.

[0023] Specifically, the positioning component 7 includes a sealing cavity 71 and a connecting groove 72 inside the rotating roller 5. The interior of the sealing cavity 71 is connected to the interior of the sealing groove 8 through the connecting groove 72. A sealing disc 73 is slidably connected inside the sealing cavity 71. A spring 74 is fixedly connected to the surface of the sealing disc 73. A steel wire rope 75 is fixedly connected to the center of the surface of the sealing disc 73. A long groove 76 is opened inside the rotating roller 5. The steel wire rope 75 passes through the interior of the long groove 76 and extends to both ends of the long groove 76. The end face of the steel wire rope 75 away from the sealing disc 73 is fixedly connected to the surface of the drive rod 2.

[0024] In this implementation scheme, by setting the positioning component 7, when the rotating roller 5 rotates outside the drive rod 2, the drive rod 2 pulls the sealing disc 73 through the wire rope 75, changing the pressure in the sealing cavity 71 and the sealing groove 8. This pressure change can precisely control the extension and retraction of the abutment plate 10. Through the extension and retraction of the abutment plate 10, the abutment and non-abutment states inside the drum are realized. Compared with the traditional manual fixing method, the drum changing operation is more convenient and efficient. The drum is fixed by pressure difference, which enhances the adaptability to drums with different inner diameters. Whether it is a standard size or a special specification drum, it can be stably fixed without additional adjustment or replacement of parts, thus improving the versatility of the equipment.

[0025] Specifically, the surface of the abutment plate 10 away from the sealing plate 9 extends to the outer surface of the rotating roller 5. Under normal conditions, the elasticity of the spring 74 causes the sealing disc 73 to slide away from the drive rod 2, and the interior of the sealing groove 8 is under high pressure.

[0026] In this embodiment, the high pressure state of the sealing groove 8 under normal conditions ensures that the abutment plate 10 always has an outward pushing force. During the roll changing process, when the roll is sleeved on the rotating roller 5, as the rotating roller 5 rotates in the opposite direction, the sealing disc 73 is reset under the action of the spring 74, the pressure of the sealing groove 8 further increases, and the abutment plate 10 tightly abuts against the inner wall of the roll.

[0027] Specifically, a bearing is installed at the connection between the fixed shaft 3 and the rotating roller 5. The fixed shaft 3 is rotatably connected to the inside of the rotating roller 5 through the bearing. A limit ring 6 is fixedly sleeved on the outer surface of the rotating roller 5. The outer surface of the wire rope 75 is slidably connected to the inside of the long groove 76. A groove is opened on the surface of the rotating roller 5 near the drive rod 2. The outer surface of the drive rod 2 is rotatably connected to the inside of the groove.

[0028] In this embodiment, the bearing installed between the fixed shaft 3 and the rotating roller 5 greatly reduces the frictional resistance when the rotating roller 5 rotates. The limiting ring 6 provides precise axial positioning for the drum, ensuring accurate installation of the drum and effectively avoiding the problem of uneven winding caused by the skewed installation of the drum, thus ensuring the winding quality.

[0029] Specifically, the fixing component 11 includes a fixing seat 111 fixedly connected to the surface of the main body 1 of the winding equipment. An arc plate 112 is rotatably connected to the surface of the fixing seat 111. A fixing pin 113 is fixedly connected to the surface of the fixing seat 111. A hydraulic cylinder 114 is rotatably connected to the outer surface of the fixing pin 113. The output end of the hydraulic cylinder 114 is rotatably connected to the surface of the arc plate 112 through a pin shaft. A slot 115 is opened on the surface of the fixing seat 111. A retaining ring 116 is fixedly connected inside the slot 115.

[0030] In this embodiment, the fixing component 11 enables the quick fixing and disassembly of the connecting rod 201. The hydraulic cylinder 114 drives the arc plate 112 to rotate, which can easily and quickly loosen or fix the connecting rod 201. In the past, fixing and disassembling the connecting components was cumbersome, required multiple people to cooperate and was time-consuming when changing rolls. Now, a single person can complete it in a short time, which greatly improves production efficiency. The structure of the slot 115 and the retaining ring 116 provides precise positioning for the connecting rod 201, ensuring that the roller 5 is accurately positioned after installation, laying the foundation for subsequent stable winding work, ensuring uniform tension during roll winding and improving the quality of finished products.

[0031] Specifically, steel balls are equidistantly installed at the connection points of the retaining ring 116 and the connecting rod 201, and at the connection points of the arc plate 112 and the connecting rod 201. The surface of the arc plate 112 near the connecting rod 201 is arc-shaped, and the connecting rod 201 is rotatably connected to the inside of the slot 115.

[0032] In this embodiment, steel balls are equidistantly installed at the connection points of the retaining ring 116 and the connecting rod 201, and at the connection points of the arc plate 112 and the connecting rod 201. This effectively reduces the friction between the connecting rod 201 and the retaining ring 116 and the arc plate 112, making the operation smoother during the installation and disassembly of the connecting rod 201. At the same time, the rotating roller 5 rotates more flexibly during the winding process, and the noise of the equipment operation is significantly reduced. The surface of the arc plate 112 near the connecting rod 201 is arc-shaped. This design fits the connecting rod 201 better, enhances the fixing effect of the connecting rod 201, and improves the stability of the connection.

[0033] The working principle and usage process of this utility model are as follows: During operation, the hydraulic cylinder 114 is activated, causing its output end to extend. Simultaneously, the arc-shaped plate 112 rotates counterclockwise around the fixing pin 113. At this time, the top of the arc-shaped plate 112 moves away from the connecting rod 201. Then, the connecting rod 201 can be slid laterally, moving it away from the retaining ring 116 and sliding it from inside the slot 115 until it disengages from the fixing seat 111. Then, by rotating the roller 5, it rotates outside the drive rod 2 via the fixed shaft 3. Simultaneously, the drive rod 2 pulls the sealing disc 73 via the wire rope 75, causing it to slide to the left. At this time, the sealing cavity 71 is under negative pressure, and the sealing groove 8 is also under negative pressure. The sealing plate 9 retracts the abutment plate 10 into the sealing groove 8. Then, the unwound roll is fitted onto the surface of the roller 5, with the end face of the roll abutting against the surface of the limiting ring 6. Then, the roller 5 is rotated in the opposite direction. Roller 5 is rotated until the center of the drive rod 2 is aligned with the rotating roller 5. Then, the connecting rod 201 is placed inside the slot 115, and the hydraulic cylinder 114 is activated to shorten it, causing the arc plate 112 to rotate clockwise. The end face of the arc plate 112 slides against the connecting rod 201 until the surface of the connecting rod 201 abuts against the steel ball on the surface of the retaining ring 116. At this time, the connecting rod 201 is positioned. When the rotating roller 5 rotates in the opposite direction, the traction force of the drive rod 2 on the sealing disc 73 is reduced through the wire rope 75. Through the elasticity of the spring 74, the sealing disc 73 slides to the right. At the same time, the sealing cavity 71 is under high pressure, and the pressure inside the sealing groove 8 is increased through the connecting groove 72. At this time, the sealing plate 9 drives the abutment plate 10 to slide to the outside of the rotating roller 5, and the surface of the abutment plate 10 abuts against the inner wall of the roll, thus fixing the roll. After the roll material is wound around the outside of the roll, the starting motor on the main body 1 of the winding equipment is activated to drive the rotating roller 5 to rotate, thereby winding the roll material.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
