Technical Field
[0001] This utility model relates to the technical field of SMC sheet winding, specifically to an automatic winding and correction device for SMC sheets. Background Technology
[0002] SMC sheet is a common composite material, mainly composed of resin, filler, and reinforcing fiber. SMC sheet is usually used for compression molding, so it needs to be wound up during the production process to facilitate subsequent processing or transportation. However, the existing automatic winding device for SMC sheet still has certain defects in use. During use, the sheet is processed in a long production line and is pulled by multiple tensioners, coating rollers, and guide rollers, which can cause the roll to deviate, affecting the winding and the appearance quality of the roll.
[0003] To overcome the above-mentioned defects, the prior art (Chinese patent CN215159552U, published on December 14, 2021) provides a sheet winding device, including a housing, a tension mechanism, and a web-correcting mechanism. The tension mechanism specifically comprises a chute, a spring telescopic rod, a rotating shaft, a roller, and a conveyor belt. The housing surface has four chutes, and a spring telescopic rod is welded to the inner wall of each chute. A rotating shaft is welded to one side of the spring telescopic rod, and a roller is mounted on the rotating shaft. A conveyor belt is mounted on the roller. The web-correcting mechanism specifically comprises a slide rod, a lead screw, a servo motor, and a PLC controller. Two slide rods are welded to the housing surface. The entire device has a good web-correcting structure, allowing for a relatively flat winding process, greatly increasing the overall aesthetics and improving product quality.
[0004] Existing technology uses the combination of spring telescopic rods, rotating shafts and rollers to correct sheet material deviation. However, due to the uncontrollable factors of spring elasticity and friction, the precise control of deviation may be affected. The complex mechanical structure requires high manufacturing precision and more parts, which not only increases production costs but may also lead to wear and failure of multiple moving parts. Frequent maintenance further increases the cost of use. At the same time, the entire device occupies a large space, affecting equipment layout and production efficiency.
[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing automatic winding and correction device for SMC sheets. Therefore, we propose that the automatic winding and correction device for SMC sheets can effectively solve the above problems. Utility Model Content
[0006] The purpose of this utility model is to provide an automatic winding and correction device for SMC sheets, in order to solve the problems mentioned in the background art. Currently, the sheet correction in the market is achieved by the cooperation of spring telescopic rods, rotating shafts and rollers. However, due to the uncontrollable factors of spring elasticity and friction, the precise control of correction may be affected. The complex mechanical structure requires high manufacturing precision and more parts, which not only increases production costs, but may also lead to wear and failure of multiple moving parts. Frequent maintenance further increases the cost of use. At the same time, the entire device occupies a large space, affecting the equipment layout and production efficiency.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic winding and correction device for SMC sheets, comprising a winding machine, a conveying roller and a winding roller on the winding machine, a mounting base on the winding machine, a sensor mounted on the side of the mounting base, a limit seat on the winding machine, and a correction roller connected to the limit seat via an adjustment component.
[0008] Preferably, the mounting base is equipped with guide rollers, and the adjustment assembly includes a motor mounted at the bottom of the limiting seat.
[0009] Preferably, the motor output end is connected to a rotating shaft, a rotating seat is mounted on the upper end of the rotating shaft, and a correction roller is provided on the upper end of the rotating seat.
[0010] Preferably, a support rod is installed at the bottom of the rotating seat, and a sliding groove is provided on the limiting seat, with the support rod being adapted to the sliding groove.
[0011] Preferably, the limiting seat is provided with an auxiliary component, the auxiliary component including a limiting plate installed on the limiting seat, a movable component being connected through the limiting plate, and a striking plate being provided at one end of the movable component.
[0012] Preferably, the winding machine is provided with a storage frame, the storage frame is provided with a discharge device, and the storage frame is connected to an adsorption plate through a shaking device.
[0013] Preferably, an eccentric wheel is installed on the outer side of the rotating shaft. After the eccentric wheel rotates, it contacts the moving part, and after the striking plate moves, it contacts the storage frame.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This SMC sheet automatic winding and correction device, when the sensor detects a sheet offset, adjusts the angle of the correction roller on the rotating seat through the adjusting component. This quickly responds to the sheet offset problem, corrects the sheet position in a timely manner, avoids uneven winding caused by offset, improves the overall winding quality, reduces the control inaccuracies caused by using elastic structures, and is set on the conveying path of the conveyor roller and the winding roller, reducing the space occupied by redundant structures and thus reducing winding efficiency. The specific details are as follows:
[0015] (1) The sensor is convenient to detect whether the sheet is deviated. The angle of the correction roller on the rotating seat is adjusted by adjusting the component. This reduces the problem of inaccurate control caused by the use of elastic structure. Overall, it reduces the space occupied by redundant structure, which leads to a decrease in winding efficiency. Moreover, the overall structure is simple and reduces the cost of use.
[0016] (2) The motor output drives the rotating seat to shift the angle through the rotating shaft, thereby adjusting the angle of the correction roller on the rotating seat. The support rod at the bottom of the rotating seat moves inside the slide groove of the limit seat, thereby making the rotating seat rotate more stably and ensuring the accuracy and reliability of the correction action.
[0017] (3) When the rotating shaft rotates, the eccentric wheel on the outside of the rotating shaft rotates, so that the eccentric wheel contacts the moving part, so that the moving part moves inside the limiting plate, which facilitates the striking plate at the end of the moving part to strike the storage frame, and facilitates the vibration of the storage frame to shake off the particles inside, thus improving the cleanliness of the sheet.
[0018] (4) The discharge component inside the storage frame works in conjunction with the adsorption plate to effectively remove fine dust and impurities from the surface of the sheet by using the principle of electrostatic adsorption, thereby improving the surface quality of the sheet and avoiding the impact of dust and impurities on the subsequent processing and performance of the sheet.
[0019] (5) When the striking plate hits the storage frame, the shaking parts inside the storage frame shake, and the dust particles on the adsorption plate are shaken off by physical vibration, so as to achieve automatic cleaning of the adsorption plate and extend the service life of the adsorption plate.

[0029] 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.
[0030] Example 1: In this example, the correction roller 11 on the rotating seat 10 is angled to quickly respond to sheet misalignment, promptly correct the sheet's position, and avoid uneven winding caused by misalignment. Figures 1-7The technical solution shown includes a winding machine 1, on which a conveyor roller 2 and a winding roller 3 are mounted. A mounting base 4 is mounted on the winding machine 1, and a sensor 6 is mounted on the side of the mounting base 4. A limit seat 7 is mounted on the winding machine 1, and a correction roller 11 is connected to the limit seat 7 via an adjusting assembly. A guide roller 5 is mounted on the mounting base 4. The adjusting assembly includes a motor 8 mounted at the bottom of the limit seat 7, with a rotating shaft 9 connected to the output end of the motor 8. A rotating seat 10 is mounted on the upper end of the rotating shaft 9, and the correction roller 11 is mounted on the upper end of the rotating seat 10. Sheets are mounted on the conveyor roller 2 of the winding machine 1, and their ends are connected to the winding roller 3 via the guide roller 5 and the correction roller 11. A drive assembly drives the conveyor roller 2 and the winding roller 3 to rotate. This reduces overall labor costs. The mounting base 4 of the winding machine 1 is equipped with... A sensor 6 is installed to detect whether the sheet is misaligned. When the sensor 6 detects a misalignment, the motor 8 on the limit seat 7 is activated. The output of the motor 8 drives the rotating shaft 9 to rotate, which in turn drives the upper rotating seat 10 to shift its angle. This allows the correction roller 11 on the rotating seat 10 to adjust its angle, thus quickly responding to the sheet misalignment and correcting its position in time. This avoids uneven winding caused by misalignment, improves the overall winding quality, and reduces the control inaccuracies caused by the use of elastic structures. The entire structure is set on the conveying route of the conveyor roller 2 and the winding roller 3, reducing the space occupied by redundant structures and the resulting decrease in winding efficiency. Furthermore, the overall structure is simple, which not only facilitates later maintenance but also reduces the cost of use.
[0031] Example 2: In this example, the striking plate 17 at the end of the moving part 15 strikes the storage frame 19, facilitating the vibration of the storage frame 19 to shake off the internal particles, thus improving the cleanliness of the sheet. Specifically, as shown below... Figures 3-6 As shown, a support rod 12 is installed at the bottom of the rotating seat 10, and a sliding groove 13 is provided on the limiting seat 7. The support rod 12 is adapted to the sliding groove 13. An auxiliary component is provided on the limiting seat 7, including a limiting plate 16 installed on the limiting seat 7. A moving part 15 is connected through the limiting plate 16. A striking plate 17 is provided at one end of the moving part 15. The support rod 12 at the bottom of the rotating seat 10 moves inside the sliding groove 13 of the limiting seat 7, thereby making the rotation of the rotating seat 10 more stable, ensuring the accuracy and reliability of the correction action, and extending the service life of the equipment. When the rotating shaft 9 rotates, the eccentric wheel 14 on the outside of the rotating shaft 9 rotates, causing the eccentric wheel 14 to contact the moving part 15, so that the moving part 15 moves inside the limiting plate 16, which facilitates the striking plate 17 at the end of the moving part 15 to strike the storage frame 19, which facilitates the vibration of the storage frame 19 to shake off the internal particles, thus improving the cleanliness of the sheet.
[0032] Example 3: In this example, the discharge element 20 and the adsorption plate 22 utilize the principle of electrostatic adsorption to effectively remove fine dust and impurities from the surface of the sheet, improving the surface quality of the sheet and preventing dust and impurities from affecting the subsequent processing and performance of the sheet. Specifically, as follows... Figures 3-7 As shown, the winding machine 1 is equipped with a storage frame 19, inside which a discharge element 20 is installed. An adsorption plate 22 is connected inside the storage frame 19 via a vibrating element 21. An eccentric wheel 14 is mounted on the outside of the rotating shaft 9. After the eccentric wheel 14 rotates, it contacts the moving part 15. After the striking plate 17 moves, it contacts the storage frame 19. Because a spring 18 is installed on the outside of the moving part 15, when the eccentric wheel 14 continues to rotate and leaves the surface of the moving part 15, the moving part 15 returns to its initial position due to the rebound of the spring 18. The elasticity of the spring 18 ensures that the moving part 15 can achieve periodic reciprocating motion, guaranteeing the continuity and stability of the striking action, improving the cleaning effect, and allowing the sheet to... During transport, the discharge element 20 inside the storage frame 19 works in conjunction with the adsorption plate 22 to effectively remove fine dust and impurities from the surface of the sheet using the principle of electrostatic adsorption, thereby improving the surface quality of the sheet and preventing dust and impurities from affecting the subsequent processing and performance of the sheet. When the striking plate 17 strikes the storage frame 19, the shaking element 21 inside the storage frame 19 vibrates, shaking off the dust particles on the adsorption plate 22 through physical vibration, thus achieving automatic cleaning of the adsorption plate 22, extending the service life of the adsorption plate 22, reducing equipment maintenance costs, and ensuring the continuity of the adsorption effect. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
