Description

Technical Field

[0001] The utility model relates to the technical field of film production, in particular to a film clamping mechanism and glue dipping equipment. Background Art

[0002] In the film cooling line, the dipping device is an extremely important part of the entire production line. The device is roughly composed of two parts: dipping and lifting. The lifting part is generally designed with two sets of clamping structures to ensure that the film can successfully climb to the corresponding height. One set is at the front of the dipping part, and the other is at the back of the lifting part.

[0003] Since the climbing angle of the rear section of the lifting part of the dipping device is relatively large, the film is often blocked in the clamping device and cannot pass smoothly, delaying production. Moreover, each time the glue is blocked, the equipment will be damaged to a certain extent. The existing technology usually uses a metal woven mesh to clamp the film to make it rise. The friction between the metal woven mesh and the metal mesh belt of the lifting part will drop metal debris onto the film, causing the rear metal detector to alarm, reducing the film conveying efficiency. At the same time, the metal mesh belt is easily damaged by friction and has a very short service life. In addition, the metal woven mesh is easy to deviate during the process of clamping the film, further reducing the film conveying efficiency.

[0004] Therefore, how to improve the film conveying efficiency is a technical problem that those skilled in the art need to solve at present. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0036] like Figure 1 and Figure 2 As shown, the film clamping mechanism disclosed in the utility model is arranged on the frame 100 of the dipping device, and includes a clamping assembly, a side plate 200 and an elastic assembly 300, wherein the clamping assembly includes a driving shaft 400, a driven shaft 401, a movable shaft 402 and a chain 403, the chain 403 is wound around the outside of the driving shaft 400, the driven shaft 401 and the movable shaft 402, the driving shaft 400, the driven shaft 401 and the movable shaft 402 are arranged in a triangle, the first end of the side plate 200 is connected to the movable shaft 402, and the second end thereof is connected to the first end of the elastic assembly 300, the middle part of the side plate 200 is fixedly connected to the frame 100, the mesh belt 500 of the dipping device is abutted against the chain 403, and the second end of the elastic assembly 300 is connected to the frame 100. Specifically, the driving shaft 400, the driven shaft 401 and the movable shaft 402 are distributed in a triangular shape, the chain 403 is wrapped around the outside of the driving shaft 400, the driven shaft 401 and the movable shaft 402 and is tensioned, and the mesh belt 500 is in contact with the chain 403 between the driving shaft 400 and the movable shaft 402, so that when the film enters between the mesh belt 500 and this part of the chain 403, it will squeeze this part of the chain 403, thereby driving the movable shaft 402 to move.

[0037] The film clamping mechanism provided by the utility model is used. When there is no film, the chain 403 is fitted with the mesh belt 500 under the deadweight of the movable shaft 402. When the film needs to be clamped, the film passes between the mesh belt 500 of the dipping device and the chain 403. The mesh belt 500 and the chain 403 clamp the film. The driving shaft 400 drives the chain 403 to transmit. Because the chain 403 is lifted by the film, the chain 403 drives the movable shaft 402 to move, and the movable shaft 402 drives the side plate 200 to rotate around the middle of the side plate 200. The film is rotated, and at the same time, the elastic component 300 at the second end of the side plate 200 applies a pulling force in the opposite direction to the side plate 200, so that the chain 403 is further pressed against the film, so as to achieve the purpose of the chain 403 and the mesh belt 500 jointly clamping the film. Because the chain 403 clamping the film will not produce a large area of ​​friction with the mesh belt 500, and the chain 403 is easier to limit, the use of the chain 403 to clamp the film can increase the service life of the mesh belt 500, reduce metal debris, and avoid displacement of the mesh belt 500 and the chain 403, thereby improving the conveying efficiency of the film.

[0038] In order to optimize the above technical solution, the film clamping mechanism also includes a transmission shaft 600, a first gear and a second gear. The first gear is connected to the transmission shaft 600, the second gear is connected to the driving shaft 400, the first gear is meshed with the second gear, and the transmission shaft 600 is used to drive the driving shaft 400 to rotate. When in use, the transmission shaft 600 rotates to drive the first gear to rotate, and the first gear is meshed with the second gear, so the first gear drives the second gear to rotate, and the second gear drives the driving shaft 400 to rotate, and finally the driving shaft 400 drives the chain 403 to drive, so that the chain 403 and the mesh belt 500 drive the film to move along the direction of the chain 403 transmission. Such an arrangement can realize the orderly transmission of the chain 403, thereby improving the film conveying efficiency of the film clamping mechanism.

[0039] In order to optimize the above technical solution, the clamping assembly further includes a positioning wheel and a chain guide wheel, which are connected to the movable shaft 402 and / or the driven shaft 401, and cooperate with the chain guide wheel to adjust the angle of the chain 403 and tighten the chain 403. Specifically, a set screw hole is provided on the positioning wheel, and the set screw passes through the set screw hole to connect the positioning wheel and the chain guide wheel together, and the set screw assists the chain guide wheel to be positioned at the corresponding position of the movable shaft 402 and / or the driven shaft 401, so as to facilitate on-site installation and debugging of the film clamping mechanism.

[0040] In order to optimize the above technical solution, the film clamping mechanism also includes a positioning shaft 700, the first end of the positioning shaft 700 is connected to the frame 100, the middle part of the side plate 200 is provided with a mounting hole, the second end of the positioning shaft 700 cooperates with the mounting hole, and the side plate 200 can rotate with the positioning shaft 700 as the rotation center. When in use, the second end of the positioning shaft 700 cooperates with the mounting hole, the film enters between the chain 403 and the mesh belt 500, the chain 403 is lifted by the film, the chain 403 drives the movable shaft 402 to move, and the movable shaft 402 drives the side plate 200 to rotate with the positioning shaft 700 as the center, and at the same time, the elastic component 300 at the second end of the side plate 200 applies a pulling force in the opposite direction to the side plate 200, so that the chain 403 is further close to the film, so as to achieve the purpose of the chain 403 and the mesh belt 500 clamping the film together. By arranging the positioning shaft 700, when the movable shaft 402 drives the first end of the side plate 200 to move, the middle part of the side plate 200 remains stable, and the second end of the side plate 200 generates a pulling force on the elastic component 300, so that the elastic component 300 is in a stretched state, and the elastic component 300 applies a reverse pulling force to the second end of the side plate 200, thereby ensuring that after the film enters between the chain 403 and the mesh belt 500, the chain 403, the film and the mesh belt 500 are always in a clamped state, thereby improving the film conveying efficiency of the film clamping mechanism.

[0041] Furthermore, the film clamping mechanism may include two relatively arranged side panels 200 and two elastic components 300, the two elastic components 300 are respectively connected to the two side panels 200, and the two side panels 200 are respectively connected to the two ends of the movable shaft 402, so that the tension of the elastic components 300 on the side panels 200 is balanced, further improving the clamping effect of the film clamping mechanism on the film.

[0042] In order to optimize the above technical solution, the elastic component 300 includes a spring plate 301, a spring rivet 302 and an elastic member 303, wherein the spring plate 301 is fixed to the frame 100, the first end of the spring rivet 302 is connected to the spring plate 301, and the second end thereof is connected to the second end of the elastic member 303, the first end of the elastic member 303 is connected to the side plate 200, and when the side plate 200 rotates, the elastic member 303 is in a stretched state. Specifically, the elastic member 303 includes but is not limited to a component capable of generating elastic tension, such as a tension spring, and the first end of the elastic member 303 is connected to the second end of the side plate 200. During use, when the film squeezes the chain 403 and the chain 403 drives the side plate 200 to rotate, the elastic member 303 is in a stretched state and applies a pulling force to the side plate 200 that is opposite to the rotation direction of the side plate 200. When the film moves out from between the chain 403 and the mesh belt 500, the elastic member 303 pulls the side plate 200 back to its original position. Such an arrangement enables the side plate 200 to move flexibly and reset in time, thereby ensuring that the chain 403 and the mesh belt 500 are always in a clamped state, maintaining the continuity of the use of the film clamping mechanism, and further improving the film conveying efficiency of the film clamping mechanism.

[0043] In order to optimize the above technical solution, a U-shaped groove is provided at the first end of the side plate 200, and the movable shaft 402 is connected to the U-shaped groove, and both ends of the movable shaft 402 extend out of the U-shaped groove. Specifically, the radial direction of the movable shaft 402 is connected to the U-shaped groove, and its two axial ends extend out of the interior of the U-shaped groove for connecting the chain 403. A bearing seat for connecting the movable shaft 402 is installed at the U-shaped groove. When in use, when there are two side plates 200 arranged opposite to each other, the two U-shaped grooves are respectively arranged on both sides of the movable shaft 402 to form a stable support connection for the movable shaft 402, thereby ensuring the stability of the movement of the movable shaft 402 and the stability of the rotation of the two side plates 200, thereby ensuring the efficiency of the film clamping mechanism in conveying the film.

[0044] In order to optimize the above technical solution, the film clamping mechanism further includes an intermediate sprocket 800, which is connected to the driving shaft 400. Specifically, the intermediate sprocket 800 cooperates with the chain 403. When in use, the driving shaft 400 drives the intermediate sprocket 800 to rotate, and the intermediate sprocket 800 drives the chain 403 to transmit, thereby realizing the movement of the film. The number of intermediate sprockets 800 connected to the driving shaft 400 is one or more. When the number of intermediate sprockets 800 is two or more, the sizes of the intermediate sprockets 800 are different. The intermediate sprocket 800 is used to support the chain 403 to improve the transmission stability of the film clamping mechanism.

[0045] Furthermore, sprockets are also connected to the driven shaft 401 and the movable shaft 402, and are used to transmit the chain 403, which will not be described in detail here.

[0046] In order to optimize the above technical solution, the number of the intermediate sprockets 800 is three. Specifically, through actual use and data calculation, when the number of the intermediate sprockets 800 is three and the sizes of the three intermediate sprockets 800 are different, the occupied space and the use effect of the film clamping mechanism can be coordinated at the same time, and the practicality of the film clamping mechanism can be improved while improving the space utilization rate of the film clamping mechanism, and its application range can be expanded.
