Description
Technical Field

[0002] In the production and processing of film materials, the continuous and stable production of the coating machine is very important. If the speed is inconsistent or the film material is not wound in time during the production process, film material accumulation and supply interruption will occur, resulting in the ineffective utilization of film materials, reduced production efficiency, uneven coating and coating defects, which in turn affect product quality. To solve these problems, a storage rack device can be added to the coating machine. The storage rack can buffer and store the film material when the film material is changed or the speed changes, and release the film material after the roll change is completed, ensuring that the film material maintains a constant linear speed throughout the production process, avoiding the accumulation of film material due to roll change or speed change, thereby ensuring product quality.
[0003] Therefore, developing a storage rack that can buffer and store high-speed coating films is of great significance for improving the quality and production efficiency of film products. Summary of the Invention

[0020] In this embodiment, the lifting component 3 includes a first movable plate 31, a first long guide roller bearing seat 32, a long guide roller 33, a second long guide roller bearing seat 34, a linear bearing 35, a second movable plate 36, a connecting rod 37 and an adjusting stud 38. The lifting component 3, the first movable plate 31 and the second movable plate 36 are symmetrically arranged in the internal frame and are connected and fixed by the connecting rod 37 and the adjusting stud 38 to form a supporting frame. Two linear bearings 35 are provided on the outside of the first movable plate 31 and the second movable plate 36 to ensure that the lifting component 3 has good stability during movement. A screw nut 43 is also provided in the middle, and a screw The rod nut 43 is rotatably connected to the screw rod 42. When the screw rod 42 rotates, the screw nut 43 can be driven to move on the screw rod 42, thereby driving the lifting assembly 3 to move through the screw nut 43. The linear bearing 35 is slidably connected to the straight rod 73. Several long guide rollers 33 are arranged on the first movable plate 31 and the second movable plate 36. The long guide rollers 33 can rotate during operation, and the surfaces are anodized to reduce damage to the film material. The long guide rollers 33 are distributed at intervals, and the two ends of the long guide rollers 33 are respectively connected to the first long guide roller bearing seat 32 and the second long guide roller bearing seat 34, and the bearing seats are fixed to the movable plate by screws.
[0021] In this embodiment, the power assembly 2 includes a servo motor 21, a coupling 22, a commutator 23, a connecting rod 24, a first RV reducer 25 and a second RV reducer 26. The commutator 23 is installed at the top position in the middle of the storage rack and is fixed to the commutator fixing seat 58 by screws. The input end of the commutator 23 is connected to the servo motor 21 through the coupling 22, and the left and right output shafts of the output end are respectively connected to the first RV reducer 25 and the second RV reducer 26 through the connecting rod 24. The commutator 23 can provide two output shafts in opposite directions, which are correspondingly connected to the reducer so that the two parallel screws have synchronous speeds, ensuring that the lifting platforms at the left and right ends have the same lifting speed. The RV reducer is fixed to the reducer fixing seat by screws, and the reducer fixing seat is installed on the upper part of the top frame 55. The RV reducer is connected to the screw assembly 4 through the coupling 22.
[0022] In this embodiment, the two ends of the short guide roller 61 are respectively connected to the first short guide roller bearing seat 62 and the second short guide roller bearing seat 63. The bearing seats are fixed to the fixed plate 54 of the base 52 by screws. A number of short guide rollers 61 are provided on the fixed plate 54, and these short guide rollers 61 are distributed at intervals and staggered with the long guide roller 33. The working roller surfaces of the short guide rollers 61 and the long guide rollers 33 have the same length and parallel end faces. The film material 1 passes through the short guide rollers 61 and the long guide rollers 33 in turn. Through the cooperation of the power component 2 and the screw component 4, the lifting component 3 can move up and down in the storage rack. When the lifting component 3 rises, the long guide roller 33 will pull the film material up, and the film material 1 is temporarily stored in the storage rack. When the lifting component 3 descends, the stored film material 1 is released.
[0023] In this embodiment, the moving speed of the lifting component 3 can be adjusted according to the running speed of the film material in the coating machine. When the film material needs to be stored, the servo motor 21 controls the lifting component 3 to lift and store the film material in the storage rack. After the coating machine finishes changing the roll, the lifting component 3 descends and releases the film material. When the coating machine is working normally, the lifting component 3 remains in a lower position to maintain a certain storage space in the storage rack. There are 5 short guide rollers in the lifting component 3. The film material lifted and stored by the lifting component 3 is 10 times the running speed of the film material.
[0024] The specific usage and function of this embodiment are as follows: See attached Figure 1-8 The storage rack in this embodiment is placed in the coating machine between the floating traction device and the compounding device. The function of the floating traction device is to provide traction power for the film material 1. At the same time, the floating roller on the device can tension the film material 1 during operation, so that the film material 1 has a stable tension. The function of the compounding device is to compound two films of different materials together to form a new roll of film. The new roll of film is pulled backward by the floating traction device and transported backward. After passing through the storage rack and the floating traction device in turn, the film material 1 is recovered by the winder. When the storage rack starts working for the first time, it is necessary to manually pull the film material 1 from the compounding device into the storage rack, and pass through the short guide roller and the long guide roller in the storage rack in turn. After the film material 1 passes through the storage rack, it reaches the floating traction device and then reaches the winder after passing through the floating traction device.
[0025] See attached Figure 1-8 In this embodiment, the storage rack has two storage states. The first state is a high storage capacity state, that is, when the lifting component 3 is in a lower position, the servo motor 21 in the storage rack does not work, and the lifting component 3 is stable in a low position. When the winding machine in the coating machine changes the roll, the overall film material running speed of the coating machine will slow down, and the traction roller in the floating traction device in front of the winding machine will be slower than the running speed of the overall film material. Since the composite device runs at a faster speed, the continuously produced film material 1 will not be recovered in the winding machine. At this time, the storage rack starts to work, the servo motor 21 starts to rotate, and the coupling 2 2 drives the commutator 23 to work. The output shafts at the left and right ends of the commutator 23 drive the first RV reducer 25 and the second RV reducer 26 to work respectively through the connecting rod 24. The rotation directions of the output shafts of the two reducers are the same, and they respectively drive the screw rods 42 connected thereto to rotate in the same direction. The screw rod 42 will drive the screw nut 43 to rise. Since the screw nut 43 is fixedly connected to the lifting assembly 3, the lifting assembly 3 will be lifted synchronously with the screw nut 43. Since the position of the lifting assembly 3 in the storage rack changes, the length of the film material 1 stored in the storage rack will increase, thereby achieving the purpose of temporary buffer storage of the film material 1.
[0026] After the winder is reset, the floating traction device returns to normal speed. At this time, the servo motor 21 in the storage rack will reverse, and after passing through the power component 2 and the screw component 4, the lifting component 3 will be controlled to descend to release the stored film material 1. When the lifting component 3 drops to the low position, the coating machine as a whole returns to normal operating speed. At this time, the storage rack is in a high-capacity state.
[0027] The foregoing description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be readily conceived by a person skilled in the art within the technical scope disclosed herein are intended to be encompassed within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
