Description

Technical Field

[0001] This utility model relates to the field of composite machine technology, specifically to a web-correcting device for composite machines. Background Technology

[0002] Laminating machines are mainly used to firmly bond two or more layers of fabrics with different properties together with adhesives, forming composite fabrics with new properties and functions. These fabrics to be laminated are diverse, including natural fiber fabrics and chemical fiber fabrics.

[0003] Chinese patent CN220723020U discloses a web-correcting device for a composite machine. This device uses a push plate and a servo motor to drive a bidirectional threaded rod to rotate, causing the push plates on both sides to move inward, thereby pushing the misaligned product towards the center, automatically correcting the product's position, and improving the quality of product processing.

[0004] The aforementioned patent uses a bidirectional threaded rod to drive two push plates to push the misaligned fabric back to the center. However, due to the strong deformation ability of the fabric, the push plates can easily cause wrinkles in the fabric during the pushing process, thus affecting the processing quality of the product. Utility Model Content

[0005] The purpose of this invention is to provide a correction device for a composite machine, which effectively solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] The web-aligning device of the laminating machine includes a frame, a drying cylinder, a discharge roller, and a take-up roller. Two vertical plates are symmetrically mounted on the upper surface of the frame between the drying cylinder and the discharge roller. A rectangular frame is installed between the two vertical plates via a web-aligning mechanism, which can move the rectangular frame horizontally left and right. A clamping and conveying mechanism is located inside the rectangular frame, which can clamp the fabric and transport it normally. Web-aligning sensors are installed at both ends of the rectangular frame facing the discharge roller.

[0008] Furthermore, the correction mechanism includes two first guide rods installed on both sides of the rectangular frame, with the ends of the first guide rods extending to the other side of the upright plate. A first electric push rod is installed on the outer surface of one of the upright plates, and the end of the telescopic end of the first electric push rod is connected to the side surface of the rectangular frame.

[0009] Furthermore, the clamping and conveying mechanism includes a conveying roller rotatably mounted inside a rectangular frame and near the bottom, a lifting plate mounted inside the rectangular frame near the top via a lifting mechanism, a first clamping wheel mounted at the center of the lower surface of the lifting plate, and second clamping wheels mounted on both sides of the lower surface of the lifting plate via a wrinkle removal mechanism.

[0010] Furthermore, the lifting mechanism includes two second guide rods installed on the upper surface of the lifting plate, and the two second guide rods are distributed on both sides of the upper surface of the lifting plate and extend through to the upper side of the rectangular frame. A first screw is rotatably installed at the middle position of the upper surface of the lifting plate, and the upper end of the first screw extends through to the upper side of the rectangular frame and is threadedly connected thereto. A torsion bar is installed at the upper end of the first screw.

[0011] Furthermore, the wrinkle removal mechanism includes two fixed blocks installed on the lower surface of the lifting plate, a second screw rotatably mounted between the two fixed blocks, and a second clamping wheel mounted on the outer surface of the second screw. A motor is mounted on the outer surface of the fixed block near the first clamping wheel, and the output shaft of the motor is connected to the second screw.

[0012] Furthermore, a limit groove is formed on the lower surface of the lifting plate along its length, and a limit block is installed on the top of the second clamping wheel, with the limit block set in the limit groove.

[0013] Furthermore, a fixing plate is installed on the outer surface of the upright plate, and a second electric push rod is installed on the outer surface of the fixing plate. The correction sensor is installed at the end of the telescopic end of the second electric push rod.

[0014] Furthermore, the outer surface of the second clamping wheel is provided with a rubber pad, and the outer surface of the rubber pad is provided with anti-slip texture.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0016] 1. This utility model uses a lifting mechanism to clamp the fabric between the conveying roller and the first clamping wheel and the second clamping wheel for conveying. When the fabric shifts position during the conveying process, the correction mechanism can drive the rectangular frame to move horizontally, thereby driving the fabric to move horizontally and achieving the purpose of position correction. During the correction process, the fabric moves synchronously with the conveying roller, the first clamping wheel and the second clamping wheel, thereby avoiding wrinkles in the fabric during correction and improving product quality.

[0017] 2. By setting up a wrinkle-removing mechanism, when wrinkles appear on the fabric during the conveying process, the wrinkle-removing mechanism can drive the second clamping wheel to move horizontally, thereby pulling the fabric horizontally to flatten the wrinkles, ensuring that the fabric is conveyed flat and improving product quality.

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.

[0024] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0025] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0026] Please see Figures 1-4The web-correcting device for a laminating machine provided by this utility model includes a frame 100, a drying cylinder 101, a discharge roller 102, and a take-up roller 103. Two vertical plates 104 are symmetrically mounted on the upper surface of the frame 100 between the drying cylinder 101 and the discharge roller 102. A rectangular frame 105 is mounted between the two vertical plates 104 via a web-correcting mechanism 200, which can drive the rectangular frame 105 to move horizontally left and right. A clamping and conveying mechanism 300 is provided on the inner side of the rectangular frame 105, which can clamp the fabric and convey it normally. Web-correcting sensors 106 are provided at both ends of the rectangular frame 105 facing the discharge roller 102.

[0027] In use, the fabric is passed through the rectangular frame 105 and clamped and conveyed from the top and bottom sides by the clamping and conveying mechanism 300. The two sides of the fabric are placed in the correction sensors 106 on both sides. The correction sensors 106 detect the position of the fabric. When the fabric is misaligned, the correction mechanism 200 can be used to push the rectangular frame 105 to move horizontally. The rectangular frame 105 drives the clamping and conveying mechanism 300 to move horizontally, thereby moving the fabric horizontally and achieving the purpose of correcting its position. Since the fabric moves synchronously with the clamping and conveying mechanism 300 during the correction process, wrinkles on the fabric are avoided during correction, thus improving product quality.

[0028] Preferably, the correction mechanism 200 includes two first guide rods 201 installed on both sides of the rectangular frame 105. The ends of the first guide rods 201 extend to the other side of the upright plate 104. A first electric push rod 202 is installed on the outer surface of one of the upright plates 104. The end of the telescopic end of the first electric push rod 202 is connected to the side surface of the rectangular frame 105.

[0029] When the correction sensor 106 detects a shift in the edge position of the fabric, the first electric push rod 202 is activated. Due to the setting of the first guide rods 201 on both sides of the rectangular frame 105, it can only move in the horizontal direction. Therefore, under the drive of the telescopic end of the first electric push rod 202, the rectangular frame 105 and the fabric can be moved horizontally to achieve position correction.

[0030] Preferably, the clamping and conveying mechanism 300 includes a conveying roller 301 rotatably mounted inside and near the bottom of a rectangular frame 105, a lifting plate 302 mounted inside and near the top of the rectangular frame 105 via a lifting mechanism 400, a first clamping wheel 303 mounted at the center of the lower surface of the lifting plate 302, and second clamping wheels 304 mounted on both sides of the lower surface of the lifting plate 302 via a wrinkle removal mechanism 500.

[0031] The fabric passes over the conveyor roller 301, and then the lifting mechanism 400 drives the lifting plate 302 to descend, so that the first clamping wheel 303 and the two second clamping wheels 304 are pressed against the upper side of the fabric. Since the rotation direction of the conveyor roller 301, the first clamping wheel 303 and the second clamping wheel 304 is consistent with the conveying direction of the fabric, the purpose of clamping and conveying the fabric is achieved.

[0032] Preferably, the lifting mechanism 400 includes two second guide rods 401 installed on the upper surface of the lifting plate 302, and the two second guide rods 401 are distributed on both sides of the upper surface of the lifting plate 302 and extend through to the upper side of the rectangular frame 105. A first screw 402 is rotatably installed at the middle position of the upper surface of the lifting plate 302. The upper end of the first screw 402 extends through to the upper side of the rectangular frame 105 and is threadedly connected thereto. A torsion bar 403 is installed at the upper end of the first screw 402.

[0033] Since the second guide rod 401 limits the lifting plate 302, the lifting plate 302 can only move in the vertical direction. Therefore, when the first screw 402 is rotated, the lifting plate 302 can be driven to move vertically up and down under the action of the threaded connection.

[0034] Preferably, the wrinkle removal mechanism 500 includes two fixed blocks 501 mounted on the lower surface of the lifting plate 302, a second screw 502 rotatably mounted between the two fixed blocks 501, and a second clamping wheel 304 mounted on the outer surface of the second screw 502. A motor 503 is mounted on the outer surface of the fixed block 501 near the first clamping wheel 303, and the output shaft of the motor 503 is connected to the second screw 502.

[0035] When clamping the fabric, the second clamping wheels 304 located on both sides should clamp the two edges of the fabric. When one of the correction sensors 106 detects that one side of the fabric is in the correct position, while the other correction sensor 106 detects that the position of the fabric has shifted, it indicates that the fabric has wrinkled. At this time, the motor 503 can be started, which drives the second screw 502 to rotate. Under the action of the threaded connection, the second clamping wheel 304 can be driven to move horizontally. The second clamping wheel 304 pulls the fabric in the horizontal direction to flatten the wrinkles, so that the fabric can be transported flat and improve product quality.

[0036] Preferably, a limiting groove 600 is formed on the lower surface of the lifting plate 302 along its length direction, and a limiting block 601 is installed on the top of the second clamping wheel 304, with the limiting block 601 disposed in the limiting groove 600.

[0037] By setting the limiting groove 600 and the limiting block 601, the limiting effect on the second clamping wheel 304 is improved, making it more stable and smooth when moving horizontally.

[0038] Preferably, a fixing plate 700 is installed on the outer surface of the upright plate 104, and a second electric push rod 701 is installed on the outer surface of the fixing plate 700. The correction sensor 106 is installed at the end of the telescopic end of the second electric push rod 701.

[0039] The position of the correction sensor 106 can be adjusted by the second electric push rod 701, thereby enabling position detection of fabrics of different widths, improving the applicability and flexibility.

[0040] The second electric push rod 701, the wrinkle removal mechanism 500, the first electric push rod 202, and the correction sensor 106 are all connected to an external controller and are uniformly controlled by the controller. This is a common existing technology, so it will not be described in detail here.

[0041] Preferably, the outer surface of the second clamping wheel 304 is provided with a rubber pad, and the outer surface of the rubber pad is provided with anti-slip texture.

[0042] The rubber pads and anti-slip textures increase the friction between the second clamping wheel 304 and the fabric, allowing the fabric to slide on the conveyor roller 301 when the second clamping wheel 304 moves horizontally to pull the fabric, thus eliminating wrinkles.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
