[0041] The technical solutions of the present application will be described clearly and completely in combination with the embodiments. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0042] As shown in Figures 1 to 5 An embodiment of the present application provides a filter cloth adjusting device for flattening and correcting the filter cloth 4 when the filter cloth 4 is wound. The filter cloth adjusting device comprises a spiral roller 11, a frame 22, a swing frame 21 and an adjusting assembly. The swing frame 21 is installed on the frame 22, and both ends of the swing frame 21 can swing up and down on the frame 22. The adjusting assembly is connected with the swing frame 21 and is used to drive the swing frame 21 to swing on the frame 22. The spiral roller 11 is rotatably installed on the swing frame 21. The swing frame 21 and the spiral roller 11 are both arranged perpendicularly to the conveying direction of the filter cloth 4. A first spiral element 111 is arranged on the left side of the spiral roller 11, and a second spiral element 112 is arranged on the right side of the spiral roller 11. The rotation directions of the first spiral element 111 and the second spiral element 112 are opposite.

[0043] The filter cloth adjusting device provided by the embodiment comprises a spiral roller 11, a rack 22, a swing frame 21 and an adjusting assembly. The swing frame 21 is installed on the rack 22, and after the swing frame 21 is installed on the rack 22, both ends of the swing frame 21 can swing up and down. The adjusting assembly is in transmission connection with the swing frame 21, and the adjusting assembly can drive the swing frame 21 to swing on the rack 22. The spiral roller 11 comprises a roller shaft and a spiral element sleeved on the roller shaft. The spiral element is fixed in the circumferential direction of the roller shaft and the circumferential direction of the roller shaft, that is, the spiral element can rotate together with the roller shaft and will not slide on the roller shaft. The swing frame 21 is provided with two oppositely arranged shaft seats 211, and both ends of the roller shaft are rotatably installed on the two shaft seats 211. In use, a driving motor is arranged to drive the roller shaft to rotate, thereby driving the spiral element to rotate. The spiral element on the left side of the spiral roller 11 is a first spiral element 111, and the spiral element on the right side of the spiral roller 11 is a second spiral element 112. The left side and the right side of the spiral roller 11 are divided from the center line of the spiral roller 11, and the rotation directions of the first spiral element 111 and the second spiral element 112 are opposite. For example, the first spiral element 111 rotates to the left, and the second spiral element 112 rotates to the right. Since the spiral roller 11 is installed on the swing frame 21, when the swing frame 21 swings, the spiral roller 11 can swing synchronously with the swing frame 21. The swing frame 21 cooperates with the spiral roller 11 to realize the flattening and deviation correction of the filter cloth 4. In order to realize this function, the swing frame 21 and the spiral roller 11 need to be arranged perpendicular to the conveying direction of the filter cloth 4.

[0044] It should be noted that the rotation direction of the spiral element also needs to correspond to the conveying direction of the filter cloth 4, so that the filter cloth 4 can be stretched and flattened. Figure 1 Taking the front direction as an example, the conveying direction of the filter cloth 4 is the front direction, the first spiral element 111 on the left side needs to rotate to the left, and the second spiral element 112 on the right side needs to rotate to the right. When the conveying direction of the filter cloth 4 is the rear direction, the first spiral element 111 on the left side needs to rotate to the right, and the second spiral element 112 on the right side needs to rotate to the left.

[0045] The initial state of the filter cloth adjusting device provided by the embodiment is that the swing frame 21 and the spiral roller 11 are both in a horizontal state. In use, the lower surface of the filter cloth 4 is in contact with the spiral roller 11. When the filter cloth 4 starts to be conveyed, the driving motor is started and drives the spiral roller 11 to rotate. Since the rotation directions of the spiral elements on the left and right sides of the spiral roller 11 are different, the filter cloth 4 can be stretched and flattened, and the wrinkles on the surface of the filter cloth 4 can be made flat. When the filter cloth 4 deviates, the swing frame 21 can be driven to swing by the adjusting assembly to correct the deviation. For example, when the filter cloth 4 deviates to the left, the adjusting assembly controls the left end of the swing frame 21 to swing upward and the right end to swing downward correspondingly, and the filter cloth 4 gradually moves to the right. When the filter cloth 4 deviates to the right, the adjusting assembly controls the right end of the swing frame 21 to swing upward and the left end to swing downward correspondingly, and the filter cloth 4 gradually moves to the left.

[0046] The filter cloth 4 adjusting device provided by the embodiment can flatten the wrinkled filter cloth 4 by arranging the spiral roller 11, and can correct the deviation of the filter cloth 4 by arranging the swing frame 21 and the adjusting assembly. The spiral roller 11 is arranged on the swing frame 21, so that the flattening and the correction can be simultaneously performed, the structure is simple, and the occupied space is smaller. Compared with the prior art, the automation level is higher, and the correction and the flattening are integrated on the same device, so that the equipment cost and the space utilization are reduced.

[0047] The filter cloth adjusting device provided by the embodiment comprises a swing frame 21, an adjusting assembly and a spiral roller 11. Figure 1 、 Figure 2 、 Figure 4 and Figure 5 The length of the spiral roller 11 is greater than or equal to the width of the filter cloth 4.
