Description

Technical Field

[0001] This utility model relates to the field of color-changing film processing technology, and in particular to a leveling device for color-changing film processing. Background Technology

[0002] In the field of color-changing film processing, the traditional installation method of take-up and untake-up rollers is cumbersome, often requiring manual operation for complex positioning and fastening, which consumes a lot of time and manpower. This results in low efficiency of pre-processing and makes it difficult to meet the needs of continuous and efficient processing. Moreover, in the past, the color-changing film processing lacked effective pre-treatment of the film material's flexibility. The flattening operation was directly performed on the relatively hard color-changing film, making it difficult for ordinary flattening devices to accurately eliminate wrinkles and unevenness on the film surface. This resulted in poor surface flatness, low dimensional accuracy, and physical properties of the finished color-changing film, which seriously affected product quality and market competitiveness. Therefore, we have launched a new flattening device for color-changing film processing. Utility Model Content

[0003] The main objective of this invention is to provide a flattening device for color-changing film processing, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] Preferably, the take-up and release rollers are located between two connecting seats, and the two connecting seats are respectively fixedly connected to two rotating rods.

[0008] Preferably, the take-up and release rollers are movably engaged between two convex slots via convex locking blocks.

[0009] Preferably, the limiting protrusion is movably engaged inside the card hole by a spring and a drive plate.

[0010] Preferably, the leveling mechanism includes a second motor and a guide rod. A bidirectional lead screw is fixedly installed at the output end of the second motor.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The take-up and release rollers use a unique convex locking block and convex locking groove to cooperate, and use limiting protrusions and springs to achieve quick and stable installation.

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] A leveling device for color-changing film processing includes a processing table 1. A heating table 2 is provided at the upper middle part of the processing table 1. Support legs 3 are fixedly installed at the four corners of the lower end of the processing table 1. Two support frames 4 are provided on the opposite sides of the two support legs 3 on the left and the two support legs 3 on the right. Support plates 5 are fixedly installed on the upper ends of the two adjacent support frames 4. Vertical frames 6 are fixedly installed on the front and rear ends of the upper ends of the two support plates 5. First motors 7 are fixedly installed on the upper front ends of the two vertical frames 6 at the front. Rotating rods 8 are provided at the output ends of the two first motors 7 and the front ends of the two vertical frames 6 at the rear. Bearings 9 are provided on the rear outer surfaces of the two rotating rods 8 at the rear. A retracting device 10 is provided between the two rotating rods 8 facing each other. Mounting shells 11 are provided at the front and rear ends of the processing table 1. A leveling mechanism 12 is provided inside the two mounting shells 11.

[0025] In this embodiment, the take-up and release device 10 includes a connecting seat 100 and a take-up and release roller 101. Two connecting seats 100 are provided. A convex locking block 102 is fixedly installed at both the front and rear ends of the take-up and release roller 101. A spring 103 is fixedly installed above the interior of each of the two convex locking blocks 102 via an inner groove. A driving plate 104 is movably installed above the interior of each of the two convex locking blocks 102 via an inner groove. A limit protrusion 10 is fixedly installed at the end of each driving plate 104 away from the spring 103. 5. The upper ends of the two connecting seats 100 are provided with convex grooves 106, and the inner walls of the two convex grooves 106 are provided with locking holes 107; the take-up and release rollers 101 are located between the two connecting seats 100, and the two connecting seats 100 are respectively fixedly connected to the two rotating rods 8; the take-up and release rollers 101 are movably locked between the two convex grooves 106 by convex locking blocks 102; the limiting protrusions 105 are movably locked inside the locking holes 107 by springs 103 and driving plates 104.

[0026] Through the above scheme: When installing the take-up and release roller 101, align the convex locking blocks 102 at both ends of the take-up and release roller 101 with the convex locking grooves 106 on the connecting seat 100, and push the take-up and release roller 101. During the process of the convex locking blocks 102 entering the convex locking grooves 106, the limiting protrusion 105 is squeezed by the inner wall of the convex locking grooves 106, which drives the driving plate 104 to compress the spring 103 and move it into the inner groove of the convex locking block 102. When the limiting protrusion 105 moves to the position of the locking hole 107, the spring 103 rebounds, pushing the driving plate 104 and the limiting protrusion 105. 5. Engage the limiting protrusion 105 into the locking hole 107 to complete the engagement of the take-up roller 101 with the connecting seat 100. At this time, the take-up roller 101 is stably located between the two connecting seats 100, and the connecting seat 100 is fixed with the rotating rod 8, providing support and a rotation base for taking up and putting down the color-changing film. When disassembling the take-up roller 101, press the limiting protrusion 105 to overcome the elastic force of the spring 103 and move it into the inner groove of the convex locking block 102, disengaging it from the locking hole 107. Then, the convex locking block 102 can be pulled out from the convex locking groove 106, and the take-up roller 101 can be removed.

[0027] In this embodiment, the leveling mechanism 12 includes a second motor 120 and a guide rod 122. A bidirectional lead screw 121 is fixedly installed at the output end of the second motor 120. A drive frame 123 is movably installed on the left and rear parts of the outer surfaces of the bidirectional lead screw 121 and the guide rod 122. Telescopic cylinders 124 are inserted and fixedly installed on the front and rear parts of the upper ends of the two drive frames 123. The output ends of two adjacent telescopic cylinders 124 are fixedly installed on a U-shaped frame 125. A leveling roller 126 is provided inside the two U-shaped frames 125. The right part of the outer surface of the bidirectional lead screw 121 is rotatably connected to the inner right wall of the mounting shell 11 located at the front. The guide rod 122 is fixedly installed inside the mounting shell 11 located at the rear.

[0028] The above scheme is as follows: The controller starts the second motor 120, and the output end of the second motor 120 drives the bidirectional lead screw 121 to rotate. Since the outer surface of the bidirectional lead screw 121 rotates in opposite directions, when it rotates, it drives the two drive frames 123 to move in opposite directions or in the same direction along the horizontal direction on the bidirectional lead screw 121 and the guide rod 122, thereby adjusting the distance between the two drive frames 123. According to the required flatness of the color-changing film, the telescopic cylinder 124 is activated. The output end of the telescopic cylinder 124 extends or shortens, driving the U-shaped frame 125 and the flattening roller 126 installed inside it to move up and down, adjusting the contact pressure between the flattening roller 126 and the color-changing film.

[0029] It should be noted that this utility model is a flattening device for color-changing film processing. During use, the roll of color-changing film to be processed is installed on the take-up and unload roller 101 of the take-up and unload device 10. The convex locking blocks 102 at both ends of the take-up and unload roller 101 are aligned with the convex locking grooves 106 on the connecting seat 100. The take-up and unload roller 101 is pushed. When the convex locking blocks 102 enter the convex locking grooves 106, the limiting protrusion 105 is squeezed by the inner wall of the convex locking groove 106, causing the driving plate 104 to compress the spring 103 and move it towards the inner groove of the convex locking block 102. When the limiting protrusion 105... 5. Move to position 107, spring 103 rebounds, pushing drive plate 104 and limiting protrusion 105 into position 107, completing the installation of take-up and release roller 101. At this time, take-up and release roller 101 is stably positioned between the two connecting seats 100. Start the first motor 7. The output end of the first motor 7 drives the rotating rod 8 to rotate, thereby driving the connecting seat 100 and the take-up and release roller 101 installed on it to rotate, and the color-changing film begins to be released. After the color-changing film is released from the take-up and release roller 101, it passes above the heating table 2 and is conveyed to the leveling mechanism 12. The color-changing film is heated. When the film is above platform 2, platform 2 heats the color-changing film, which softens the film material, increases its flexibility, and facilitates subsequent leveling operations. The controller activates the telescopic cylinder 124, which extends or retracts, causing the U-shaped frame 125 and the leveling roller 126 installed inside it to move up and down, adjusting the contact pressure between the leveling roller 126 and the color-changing film. Then, the controller activates the second motor 120, whose output drives the bidirectional lead screw 121 to rotate. During rotation, the two drive frames 123 move bidirectionally... The lead screw 121 and guide rod 122 move in opposite directions or in the same direction in the horizontal direction. At this time, the two leveling rollers 126 can squeeze and level the color-changing film to eliminate wrinkles, unevenness and other defects on the surface of the color-changing film, making the surface of the color-changing film smoother and flatter, ensuring dimensional accuracy, and improving physical properties. After leveling, the color-changing film is wound up by another set of take-up and unwinding devices 10. The first motor 7 reverses and drives the rotating rod 8 to rotate in the opposite direction. The connecting seat 100 and the take-up and unwinding rollers 101 rotate in the opposite direction, and the leveled color-changing film is wound onto the take-up and unwinding rollers 101.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
