[0039] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0040] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, etc., indicating the directional or positional relationship, are based on the directional or positional relationship shown in the drawings and are only for the convenience of describing this utility model and simplifying the description, 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, and therefore should not be construed as a limitation of this utility model.

The use of "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or the order in which the indicated technical features are presented.
[0042] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0043] This utility model provides a pneumatic pressure plate device for strip coils, installed between crescent-shaped shears and the alkaline washing tank of a degreasing unit. The crescent-shaped shears are used to cut the strip coil, and the alkaline washing tank of the degreasing unit is used to clean the surface of the strip coil. Traditional strip coil processing systems do not include the pneumatic pressure plate device of this embodiment. Therefore, the strip coil directly enters the alkaline washing tank of the degreasing unit after passing through the crescent-shaped shears for cleaning. However, in actual production, it has been found that the tail of the strip coil cannot overcome its own weight and the weight of the alkaline washing solution, causing the tail to swing and hit the nozzle of the spray pipe below the alkaline washing tank of the degreasing unit, thus causing abrasions on the surface of the strip coil, affecting the surface quality of the strip coil, and potentially damaging the nozzle. To solve the above technical problems, this embodiment proposes a pneumatic pressure plate device to press the strip coil between the crescent-shaped shears and the alkaline washing tank of the degreasing unit. Practice has proven that by adding the pneumatic pressure plate device of this embodiment, the loss of tension and swinging of the strip tail can be effectively prevented, thereby effectively avoiding strip coil abrasions and nozzle damage. The following is combined with… Figures 1 to 6 The pneumatic pressure plate device of this embodiment will be described in detail.
[0044] Reference Figures 1 to 6The pneumatic pressure plate device of this embodiment includes a bracket 100, a lower pressure plate 200, an upper pressure plate 300, a drive structure 400, and an idler roller 500. The lower pressure plate 200 is mounted on the bracket 100, and the upper pressure plate 300 is mounted above the lower pressure plate 200. The strip roll passes between the upper pressure plate 300 and the lower pressure plate 200 and enters the alkaline washing tank of the degreasing unit. The drive structure 400 is mounted on the bracket 100, and the movable end of the drive structure 400 is connected to the upper pressure plate 300. The drive structure 400 is used to drive the upper pressure plate 300 to move vertically up and down, so as to limit the strip roll located between the upper pressure plate 300 and the lower pressure plate 200. The idler roller 500 is mounted on the bracket 100 and is located on the side of the bracket 100 away from the alkaline washing tank of the degreasing unit. In the vertical direction, the top of the idler roller 500 is higher than the upper surface of the lower pressure plate 200. The pneumatic pressure plate device for the strip roll in this embodiment, by setting up a pneumatic pressure plate device before the strip roll enters the alkaline washing tank of the degreasing unit, and the pneumatic pressure plate device includes an upper pressure plate 300 and a lower pressure plate 200 arranged opposite each other in the vertical direction, the upper pressure plate 300 descends relative to the lower pressure plate 200 to clamp the strip roll located between the upper pressure plate 300 and the lower pressure plate 200, which can effectively prevent the strip roll tail from losing tension and swinging, causing abrasions or damage to the nozzles below the alkaline washing tank of the degreasing unit. By setting up idler rollers 500 to guide and lift the strip roll, the tail of the strip roll can be further prevented from swinging, improving the stability of the strip roll conveying.
[0045] In the embodiments of this utility model, reference is made to Figure 1 , Figure 2 As shown, the idler roller 500 is rotatably mounted on the bracket 100 around its own axis. During the conveying process of the belt roll, the belt roll will fall onto the surface of the idler roller 500. The movement of the belt roll will drive the idler roller 500 to rotate, thereby effectively preventing the idler roller 500 from scratching the surface of the belt roll. Since the belt tail itself has a moving weight, when the belt tail passes through the idler roller 500 and enters between the upper pressure plate 300 and the lower pressure plate 200, the belt tail will descend under its own weight. Therefore, by setting the top of the idler roller 500 higher than the upper surface of the lower pressure plate 200 in the vertical direction, the belt tail can slide in by its own weight before entering the upper pressure plate 300 and the lower pressure plate 200, without fluctuating from bottom to top, thus preventing the belt tail from swinging.
[0046] It is important to understand that, in the vertical direction, the height of the 500 idler roller is the same as the height of the conveyor roller in the middle of the crescent shear, which makes the conveying of the roll smoother.
[0047] It is conceivable that the idler roller 500 can also be configured to not rotate around its own axis. By covering the surface of the idler roller 500 with a buffer layer, scratches on the surface of the roll can also be avoided.
[0048] In embodiments of this utility model, multiple drive structures 400 are provided, and the multiple drive structures 400 are spaced apart along the length direction of the upper pressure plate 300. The movable ends of the multiple drive structures 400 are all connected to the upper pressure plate 300, and the multiple drive structures 400 operate synchronously. Specifically, refer to... Figure 1 As shown, this embodiment has two drive structures 400, which are spaced apart along the length of the upper pressure plate 300. Both drive structures 400 use the same equipment, thus reducing maintenance costs. The drive structures 400 can be telescopic cylinders, telescopic hydraulic cylinders, electric telescopic devices, etc., and a suitable telescopic device can be selected according to the actual situation. The movable end of the drive structure 400 is connected to the upper pressure plate 300 via a connector; the specific structure of the connector is not limited in this embodiment. Having multiple drive structures 400 operating synchronously along the length of the upper pressure plate 300 allows for a more uniform downward force applied to the upper pressure plate 300, and also effectively reduces the deformation of the upper pressure plate 300 under its own weight.
[0049] In an embodiment of this utility model, a first buffer pad 210 is installed on the upper part of the lower pressure plate 200; in the vertical direction, the top of the idler roller 500 is higher than the upper surface of the first buffer pad 210. Specifically, refer to... Figure 2 , Figure 3 As shown, a second buffer pad 310 is installed at the bottom of the upper pressure plate 300. The vertical lifting of the upper pressure plate 300 can drive the second buffer pad 310 to move synchronously. When the upper pressure plate 300 moves closer to the lower pressure plate 200, the first buffer pad 210 and the second buffer pad 310 will move closer to each other. The upper pressure plate 300 and the lower pressure plate 200 preferably have the same size and shape. Similarly, the first buffer pad 210 and the second buffer pad 310 preferably have the same size and material. In this embodiment, both the first buffer pad 210 and the second buffer pad 310 are preferably wool felt. By installing the first buffer pad 210 on the lower pressure plate 200 and the second buffer pad 310 on the upper pressure plate 300, the friction between the upper pressure plate 300, the lower pressure plate 200 and the tape roll can be increased while avoiding scratching the surface of the tape roll.
[0050] In embodiments of this invention, the first buffer pad 210 is detachably connected to the lower pressure plate 200, and / or the second buffer pad 310 is detachably connected to the upper pressure plate 300. Specifically, it is preferable that the first buffer pad 210 is detachably connected to the lower pressure plate 200, and the second buffer pad 310 is also detachably connected to the upper pressure plate 300, thereby facilitating the individual replacement of the first buffer pad 210 and / or the second buffer pad 310 and reducing maintenance costs.
[0051] In an embodiment of this utility model, the upper pressure plate 300 is equipped with a backing plate 320 and a locking bolt 330. The locking bolt 330 passes through the backing plate 320 and is threadedly connected to the upper pressure plate 300. A second buffer pad 310 covers the upper pressure plate 300, and the edge of the second buffer pad 310 is located between the backing plate 320 and the upper pressure plate 300. Specifically, refer to... Figure 4 As shown, threaded holes are provided on both sides of the upper pressure plate 300 in the width direction. Locking bolts 330 are installed in the threaded holes, thereby locking the second buffer pad 310 to the upper pressure plate 300. (Refer to...) Figure 3 As shown, multiple threaded holes are provided along the length of the upper pressure plate 300, and these multiple threaded holes are spaced apart; multiple locking bolts 330 are provided corresponding to the threaded holes, and multiple abutment plates 320 are provided corresponding to the locking bolts 330. The abutment plate 320 is provided to increase the contact area between the locking bolts 330 and the second buffer pad 310, thereby reducing the probability of the second buffer pad 310 detaching from the upper pressure plate 300; setting the second buffer pad 310 to cover the upper pressure plate 300 can effectively increase the contact area between the second buffer pad 310 and the tape roll.
[0052] Furthermore, the locking bolt 330 is connected to the upper part of the upper pressure plate 300, and when the abutment plate 320 is fixed, there is still a gap between the bottom of the abutment plate 320 and the lower surface of the upper pressure plate 300, which can effectively prevent the abutment plate 320 from contacting and scratching the tape roll.
[0053] In the embodiments of this utility model, the first buffer pad 210 is fixed to the lower pressure plate 200 in the same way as the second buffer pad 310 is fixed to the upper pressure plate 300.
[0054] In an embodiment of this utility model, a limiting plate 340 is installed on the upper pressure plate 300, and the lifting and lowering of the upper pressure plate 300 drives the limiting plate 340 to lift and lower synchronously; the bracket 100 is provided with a limiting frame 110, and the limiting plate 340 can abut against the limiting frame 110 to limit the upper pressure plate 300 at the end of its stroke. Specifically, refer to... Figure 1 , Figure 5 As shown, two limit frames 110 are provided, each located at one end of the upper pressure plate 300 along its length. Two limit plates 340 are also provided, corresponding to the limit frames 110, with each plate corresponding to one of the limit frames 110. The limit plates 340 are installed on the side of the upper pressure plate 300 facing away from the lower pressure plate 200, and both ends of the upper pressure plate 300 along its length are equipped with limit plates 340. The two limit frames 110 and two limit plates 340 serve as backups for each other and also ensure that the travel at both ends of the upper pressure plate 300 is equal.
[0055] In the embodiments of this utility model, reference is made to Figure 6As shown, the limiting plate 340 includes a connecting portion 341 and an extension portion 342. The connecting portion 341 is connected to the upper pressure plate 300 by fasteners, and the extension portion 342 extends out of the upper pressure plate 300 along its length and can abut against the limiting frame 110. Specifically, the connecting portion 341 is connected to the upper pressure plate 300 by fasteners such as bolts, and the extension portion 342 is connected to the connecting portion 341 as an integral structure.
