According to its material, it can be roughly divided into papermaking copper mesh, stainless steel papermaking mesh, plastic papermaking mesh, polyester papermaking mesh, papermaking felt, papermaking mesh blanket, etc., and cylindrical papermaking mesh is a common form of papermaking mesh. In order to cooperate with the use of papermaking machines, the papermaking mesh will be shaped into a required size cylinder during the production process of the papermaking mesh; in the existing papermaking mesh production process, the cylindrical papermaking mesh is generally shaped into a cylinder by manual or rolling equipment, and then welded (or bonded) after the shaping is completed to achieve the connection of the ends of the papermaking mesh, but such a molding method has the problems of non-standard molding size and low molding efficiency; the existing public document CN106592314A-A rapid pressing and fixing device for cylindrical molding of papermaking mesh also discloses a method for molding a cylindrical papermaking mesh, but this papermaking mesh cannot be tested for its firmness during molding, which makes it difficult to grasp the molding quality and has a large degree of variation;

[0004] Therefore, it is necessary to improve the prior art to solve the above-mentioned technical problems. Summary of the invention

[0005] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments.

A second guide post 204c-2 is fixedly arranged in the groove 204c-1, and its axis extends along the radial direction of the linkage ring 204 and is used for the second movable block 203a-2 to be slidably sleeved, so as to achieve the function of limiting and guiding the movement of the second movable block 203a-2, and a third spring 204c-3 is slidably sleeved on the second guide post 204c-2 on the side of the second movable block 203a-2 close to the linkage ring 204, and the third spring 204c-3 can realize the second movable block 20 3a-2 is reset, a cylinder 201a whose axis extends along the radial direction of the arc pressure plate 201 is fixed in the middle of the top surface of the arc pressure plate 201, and the fixed section of the cylinder 201a is fixedly sleeved on the fixed plate 101a, and third T-shaped columns 201a-1 are symmetrically fixed on the top surfaces of the arc pressure plates 201 on both sides of the cylinder 201a, and the free ends of the third T-shaped columns 201a-1 are slidably sleeved on the fixed plate 101a. This arrangement can limit the expansion and contraction of the cylinder 201a The end of the fixed plate 101a close to the linkage ring 204 is fixedly connected to the top surface of the base plate 101 for guiding; a side of the arc movable plate 203 close to the arc pressure plate 201 is fixedly provided with an arc plug plate 203b coaxial with the arc pressure plate 201 and covering the outside of the arc pressure plate 201, and a U-shaped clamping plate 201b for sliding and inserting the arc plug plate 203b is fixedly provided on the outer wall of the arc pressure plate 201, thereby realizing the driving effect of the arc pressure plate 201 on the arc movable plate 203;

[0046] The top surface of the side wall of the locking disk 104 is fixedly connected to the fixed plate 101a through a connecting block, one end of the limiting arc rod 105 is fixedly connected to the connecting block, and the connecting end of the limiting arc rod 105 and the linkage block 204c are respectively arranged on both sides of the connecting block; the outer wall of the limiting arc rod 105 is also fixedly connected to the top surface of the base plate 101, the limiting arc rod 105 is arranged between the arc pressure plate 201 and the linkage ring 204, and the curvature of the limiting arc rod 105 is α, and 270°≤α≤330°, so that when the linkage block 204c moves to the position of the notch of the limiting arc rod 105, the linkage plate 203a can be moved along the axis direction of the second guide column 204c-2, thereby realizing the separation between the arc movable plate 203 and the reducer;

[0047] When the above arrangement is in use, the extension of the cylinder 201a can drive the arc pressure plate 201 to approach the outer wall of the reducer to achieve the pressing of the papermaking net on the outer wall of the reducer. With the cooperation of the arc plug plate 203b and the U-shaped clamping plate 201b, the arc pressure plate 201 moves downward, and the arc movable plate 203 also makes the papermaking net fit to the outer side of the reducer by approaching the reducer. Under this action, the clamping column 203a-1 moves from the notch of the limiting arc rod 105 to the position between the limiting arc rod 105 and the locking disk 104, and then the second toothed disk 302 drives the linkage ring 204 to move, and the clamping column 203a-1 It will make an arc motion under the limitation of the inner wall of the limiting arc rod 105, and finally realize the arc movable plate 203 to extrude the papermaking screen, so that the papermaking screen can better fit the outer side of the variable diameter cylinder, and realize rapid forming. After the arc movable plate 203 forms the papermaking screen, the arc movable plate 203 is reset to the notch of the limiting arc rod 105. At this time, under the contraction of the cylinder 201a and the cooperation of the arc plug plate 203b and the U-shaped clamping plate 201b, the third spring 204c-3 can make the second movable block 203a-2 move in the axial direction of the second guide column 204c-2, and the arc pressure plate 201 and the arc movable plate 203 are both reset.

[0048] In addition, it should be noted that in actual use, a feeding mechanism is provided on one side of the device close to the arc movable plate 203 to realize automatic transportation of the plate-shaped papermaking net, and a connecting mechanism is also provided on the other side of the device to realize the connection of the ends of the cylindrical papermaking net after forming; the device also includes a controller (not shown in the accompanying drawings) for controlling the various electrical components in the device, and the controller is arranged in a position convenient for the staff to operate. Example 2

[0049] Reference Figure 7 , Figure 8 , Fig.12 and Fig.13 , which is the second embodiment of the present invention, is based on the previous embodiment, but is different in that this embodiment is proposed in order to achieve good forming and connection effects when facing papermaking nets of different materials.

[0050] Specifically, arc pieces 203c coaxial with the arc pressing plate 201 are symmetrically fixed at two ends of the arc movable plate 203 away from the arc pressing plate 201, and two pressing rollers 203c-2 are arranged along the arc direction between the two arc pieces 203c, a rotating rod 203c-1 is slidably sleeved in the pressing roller 203c-2, and the two ends of the rotating rod 203c-1 are respectively fixedly connected to the two arc pieces 203c, and a connecting seam is formed between the two pressing rollers 203c-2. When the arrangement is in use, the setting of the pressing roller 203c-2 can assist in pressing the papermaking net to improve the forming efficiency. The design of the connecting seam can realize the connection of the overlapping position through the connecting seam position when the two ends of the papermaking net are in an overlapping state after connection (for example, a plastic papermaking net), and when the two ends of the papermaking net are not in an overlapping state when connected, but only in an aligned state (for example, a stainless steel papermaking net), the connecting seam is not required.

[0051] In addition, the connecting mechanisms selected for different materials are not the same. For example, when facing a papermaking mesh made of metal, the connecting mechanism can be a welding head. When facing a papermaking mesh made of plastic, the connecting mechanism can be a hot press head, etc. The specific structure of the connecting mechanism is selected with the purpose of ultimately achieving effective connection between the two ends of the papermaking mesh.

[0052] Furthermore, an arc patching plate 202 is coaxially arranged with the arc pressing plate 201 on the other side of the arc pressing plate 201 on which the arc moving plate 203 is arranged, and a connecting plate 202a and a magnetic plate 202b are arranged above the arc patching plate 202 in sequence, and both ends of the bottom surface of the magnetic plate 202b are fixedly connected to the arc patching plate 202 through a guide rod 202b-1, and the connecting plate 202a fixedly connected to the arc pressing plate 201 is slidably sleeved on the guide rod 202b-1 to achieve the function of limiting guidance, and the axis of the guide rod 202b-1 is arranged along the radial direction of the arc patching plate 202, and a second electromagnetic plate 202a-1 is fixedly arranged on the top surface of the connecting plate 202a, and a second spring 202b-2 is slidably sleeved on the guide rod 202b-1 between the connecting plate 202a and the magnetic plate 202b, and the second spring 202b-2 can realize the reset of the arc patching plate 202;

[0053] When the above-mentioned arrangement is in use, by energizing the second electromagnetic plate 202a-1, magnetism can be generated to magnetically adsorb the magnetic attraction plate 202b. Under the action of the magnetic adsorption, the connecting plate 202a drives the arc patch plate 202 to move downward so as to fit onto the papermaking net on the outside of the papermaking net to achieve the molding of its end. When the second electromagnetic plate 202a-1 is powered off, under the resetting action of the second spring 202b-2, the arc patch plate 202 moves upward for resetting. It should be noted that the setting of the arc patch plate 202 is mainly for the molding of papermaking nets with higher hardness, such as stainless steel papermaking nets. Example 3

As the diameter-changing disk 103 rotates, when the first T-shaped column 102b-1 moves into the outward expansion groove 103b-2, the first movable block 102b will also synchronously move outward in the axial direction of the first guide column 104c-1, and finally realize the synchronous outward expansion of multiple shaping plates 102, so as to provide an extrusion force from the inside of the papermaking net cylinder after the cylindrical papermaking net is formed, so as to facilitate the inspection of the papermaking net after forming and detect its firmness. When the first T-shaped column 102b-1 moves into the inner receiving groove 103b-1, the multiple shaping plates 102 synchronously shrink inward, and the papermaking net cylinder is separated from the diameter-changing cylinder, so that the staff can easily remove the formed papermaking net from the diameter-changing cylinder.

Through this arrangement, the shaping plate 102 can be disassembled and replaced by twisting the locking nut 102a-1 with a tool, thereby making effective adaptive adjustments when facing the forming of papermaking nets of different sizes and the maintenance of the shaping plate 102.

The first electromagnetic plate 306 is fixedly arranged on the top surface of the base plate 101 on one side of the second connecting strip 305b. Finally, the first electromagnetic plate 306 can realize the synchronous movement of the fourth T-shaped column 304b and the linkage column 305 under the magnetic adsorption of the second connecting strip 305b;

[0062] When the above arrangement is in use, through the magnetic adsorption effect of the first electromagnetic plate 306 on the second connecting strip 305b, combined with the reset effect of the fourth spring 304c, the linkage column 305 can be moved back and forth in the axial direction, and finally the positioning column 305d can be selectively inserted into the first hole 301a or the second hole 302a.
