[0002] The filter cloth hot pressing device is mainly used for hot pressing filter cloth to improve its performance and service life. It mainly uses the heating plate in the hot pressing mechanism to heat the filter cloth to make it reach certain temperature and pressure conditions. Through heating and pressurization, the fiber structure inside the filter cloth can be made more compact, thereby enhancing its mechanical strength, enabling it to better withstand various stresses and tensile forces during use, and its water resistance will also be improved, which is particularly important for filter cloth working in humid or liquid environments and can extend its service life.

[0003] The common filter cloth hot pressing device realizes the hot pressing operation of the filter cloth by pressing down the heating plate to be in close contact with the filter cloth. However, in the actual use process, due to the different thicknesses of the filter cloth, when the pressure applied by the hot pressing plate is constant, the hot pressing effects on filter cloths with different thicknesses are different, which affects the hot pressing effect of the filter cloth and results in inconsistent hot pressing quality of the filter cloth. Therefore, we provide a hot pressing device for industrial filter cloth production to solve the above technical problems. Summary of the Utility Model

The first hot pressing support plate, the second hot pressing support plate, and the horizontal support plate are slidably arranged between the two support columns. A metal heating rod is fixedly connected inside the hollow hot pressing roller, and the metal heating rod is electrically connected to an external power supply. An adjusting spring is fixedly connected between the first hot pressing support plate and the horizontal support plate, and the adjusting spring is sleeved outside the corresponding transmission support column.

[0008] The present utility model is further configured such that an electric push rod is fixedly installed on the upper surface of the hot pressing box body, and the output end of the electric push rod is fixedly connected to the first hot pressing support plate. Support connecting rods are rotatably arranged on opposite side surfaces of the hot pressing box body.

[0009] The present utility model is further configured such that the feeding assembly further includes a hollow support frame symmetrically and fixedly connected to a side surface of the hot pressing box body close to the feeding port. Two horizontal support plates are symmetrically and slidably arranged inside the hollow support frame. The feeding roller is rotatably connected between the two horizontal support plates, and a first return spring is fixedly connected between the horizontal support plate and the inner wall of the hollow support frame.

By controlling the synchronous rotation of the winding roller and the feeding rollers, while driving the filter cloth to move towards the hot pressing box body, the filter cloth after hot pressing is wound. At the same time, the pressing limiting plate always closely adheres to the outermost filter cloth on the winding roller, so as to realize the feeding and winding of the filter cloth, keep the winding of the filter cloth tight, and avoid loose winding.

[0014] Of course, it is not necessary for any product implementing the utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention. Specific embodiment one

[0026] Please refer to Figures 1-6 , the present invention is a hot pressing device for industrial filter cloth production, including a hot pressing box body 1. A first hot pressing support plate 101 and a second hot pressing support plate 102 are respectively slidably arranged inside the hot pressing box body 1. Two transmission support pillars 103 are symmetrically and slidably arranged on the surface of the first hot pressing support plate 101. One end of the transmission support pillar 103 is fixedly connected with an electromagnetic ring 104 (there is a certain distance between the electromagnetic ring 104 and the inner wall of the hot pressing box body 1. When the electromagnetic ring 104 moves downward, the transmission support pillar 103 moves downward synchronously). The electromagnetic ring 104 is electrically connected to an external power source. Two magnetic attraction rings 105 are symmetrically and fixedly connected to the upper surface of the first hot pressing support plate 101. The magnetic attraction ring 105 is adapted to the corresponding electromagnetic ring 104. The other end of the transmission support pillar 103 passing through the first hot pressing support plate 101 is fixedly connected with a horizontal support plate 106. When the magnetic attraction ring 105 is magnetically attracted to the corresponding electromagnetic ring 104, the first hot pressing support plate 101 moves up and down, driving the horizontal support plate 106 to move up and down synchronously. Two hollow hot pressing rollers 107 are symmetrically and rotatably arranged on the lower surface of the horizontal support plate 106 and the upper surface of the second hot pressing support plate 102 through ear plates; A feeding assembly 2 is fixedly installed on one side surface of the hot pressing box body 1. The feeding assembly 2 includes two symmetrically and rotatably arranged feeding rollers 201, and the rotation of the feeding rollers 201 drives the filter cloth to move into the hot pressing box body 1; A rewinding assembly 3 is fixedly installed on the opposite side surface of the hot pressing box body 1. The rewinding assembly 3 includes a rotatably arranged rewinding roller 301, and the rotation of the rewinding roller 301 winds the hot pressed filter cloth on the circumferential side surface of the rewinding roller 301.

[0027] The operation process of this embodiment is as follows: When hot pressing the filter cloth is required, the electromagnetic ring 104 is controlled to be energized, so that the electromagnetic ring 104 and the corresponding magnetic attraction ring 105 are adsorbed to each other. When the first hot pressing support plate 101 moves downward, it drives the horizontal support plate 106 to move downward synchronously. At the same time, the second hot pressing support plate 102 moves upward until the hollow hot pressing rollers 107 on the horizontal support plate 106 and the second hot pressing support plate 102 are respectively in contact with the upper and lower surfaces of the filter cloth. Then, the power supply of the electromagnetic ring 104 is disconnected. According to the thickness of the filter cloth, the first hot pressing support plate 101 is controlled to continue moving downward, so that the pressure on the filter cloth increases, facilitating the pressure drying operation of the filter cloth. At the same time, during the hot pressing process, one end of the filter cloth is fixed on the winding roller 301, and the feeding roller 201 and the winding roller 301 are controlled to rotate synchronously. Under the cooperative action of the two feeding rollers 201, the filter cloth is continuously conveyed into the hot pressing box body 1 for hot pressing operation. Specific Embodiment Two

[0029] Please refer to Figures 1-6 , on the basis of Specific Embodiment One, specifically, feeding ports and discharging ports are respectively formed on the opposite two side surfaces of the hot pressing box body 1. Two support columns 108 are symmetrically and fixedly connected between the opposite two inner side walls of the hot pressing box body 1. The first hot pressing support plate 101, the second hot pressing support plate 102 and the horizontal support plate 106 are slidably arranged between the two support columns 108, and the horizontal support plate 106 is located between the first hot pressing support plate 101 and the second hot pressing support plate 102; a metal heating rod 109 is fixedly connected inside the hollow hot pressing roller 107, and the metal heating rod 109 is electrically connected to an external power supply. The hollow hot pressing roller 107 is made of a heat-absorbing material. When the metal heating rod 109 is energized, the temperature of the metal heating rod 109 rises, and the temperature is transmitted to the hollow hot pressing roller 107. A regulating spring 110 is fixedly connected between the first hot pressing support plate 101 and the horizontal support plate 106, and the regulating spring 110 is sleeved outside the corresponding transmission pillar 103.

[0030] An electric push rod 111 is fixedly installed on the upper surface of the hot pressing box body 1, and the output end of the electric push rod 111 is fixedly connected to the first hot pressing support plate 101; support connecting rods 112 are rotatably arranged on the opposite two side surfaces of the hot pressing box body 1, and transmission connecting rods 113 are rotatably connected to both ends of the support connecting rods 112. One of the transmission connecting rods 113 is rotatably connected to one side surface of the first hot pressing support plate 101, and the other transmission connecting rod 113 is rotatably connected to one side surface of the second hot pressing support plate 102. Under the connection of the support connecting rods 112, the two transmission connecting rods 113 are driven to rotate synchronously, so that the first hot pressing support plate 101 and the second hot pressing support plate 102 move synchronously closer to or away from each other.

[0031] Further, the feeding assembly 2 further includes a hollow support frame 202 symmetrically and fixedly connected to the side surface of the hot pressing box body 1 close to the feeding port. Two horizontal support plates 203 are symmetrically and slidably arranged inside the hollow support frame 202. The feeding roller 201 is rotatably connected between the two horizontal support plates 203. A first return spring 204 is fixedly connected between the horizontal support plate 203 and the inner wall of the hollow support frame 202. The filter cloth is placed between the two feeding rollers 201. By controlling the rotation of the corresponding feeding roller 201, the filter cloth is driven to move under the combined action of the two feeding rollers 201. A guiding chute 205 is formed on one side surface of one of the hollow support frames 202. A transmission block fixedly connected to the corresponding horizontal support plate 203 is slidably arranged inside the guiding chute 205. A first driving motor is fixedly installed on one side surface of the transmission block. The output shaft of the first driving motor is fixedly connected to the corresponding feeding roller 201.

[0032] Further, the winding assembly 3 further includes a hollow support plate 302 fixedly connected to the side surface of the hot pressing box body 1 close to the discharging port. The winding roller 301 is rotatably connected to one side surface of the hollow support plate 302. A second driving motor is fixedly installed on the other side surface of the hollow support plate 302. The output shaft of the second driving motor is fixedly connected to the winding roller 301. A partition support plate is fixedly connected inside the hollow support plate 302. A pressing and limiting plate 303 is fixedly connected to one side surface of the partition support plate. A second return spring 304 is fixedly connected between the partition support plate and the inner wall of the hollow support plate 302.

[0033] The operation process of this embodiment is as follows: Manually adjust the distance between the two feeding rollers 201. The horizontal support plates 203 move horizontally synchronously, so that the first return spring 204 is compressed. Pass the filter cloth to be hot pressed through the two feeding rollers 201, and fix one end of the filter cloth on the winding roller 301. After releasing the two feeding rollers 201, under the elastic recovery action of the first return spring 204, the filter cloth is clamped and limited. Start the first driving motor to drive the corresponding feeding roller 201 to rotate, and at the same time start the second driving motor to drive the winding roller 301 to rotate synchronously. The friction between the two feeding rollers 201 and the filter cloth is used to drive the filter cloth to move into the hot pressing box body 1.

[0034] Before the hot pressing operation on the filter cloth, connect the power supply of the electromagnetic ring 104 so that the electromagnetic ring 104 and the corresponding magnetic attraction ring 105 are adsorbed and closely attached to each other. At the same time, connect the power supply of the metal heating rod 109 so that the metal heating rod 109 heats up and radially heats the hollow hot pressing roller 107. When the hollow hot pressing roller 107 is heated to a certain temperature, start the electric push rod 111 to drive the first hot pressing support plate 101 to move downward. Under the magnetic attraction of the electromagnetic ring 104 and the magnetic attraction ring 105, as the first hot pressing support plate 101 moves downward, the magnetic attraction ring 105 moves downward synchronously. Since the electromagnetic ring 104 and the magnetic attraction ring 105 are magnetically attracted to each other, the electromagnetic ring 104 moves downward synchronously. Under the connection of the transmission support column 103, the horizontal support plate 106 moves downward synchronously with the first hot pressing support plate 101. At the same time, during the downward movement of the first hot pressing support plate 101, the transmission connecting rods 113 on both sides are driven to rotate, and the support connecting rod 112 is driven to rotate through the corresponding transmission connecting rod 113. Under the rotation of the support connecting rod 112, the transmission connecting rods 113 on both sides of the second hot pressing support plate 102 are pulled, so that the transmission connecting rods 113 on both side surfaces of the second hot pressing support plate 102 rotate, driving the second hot pressing support plate 102 to move upward until the hollow hot pressing rollers 107 on the horizontal support plate 106 and the second hot pressing support plate 102 are respectively attached to the upper and lower surfaces of the filter cloth. Then, disconnect the power supply of the electromagnetic ring 104. According to the thickness of the filter cloth, control the first hot pressing support plate 101 to continue moving downward. Since the electromagnetic ring 104 is powered off, the magnetic attraction between the electromagnetic ring 104 and the magnetic attraction ring 105 disappears. As the first hot pressing support plate 101 moves downward, the transmission support column 103 slides along the first hot pressing support plate 101, and the interval between the electromagnetic ring 104 and the magnetic attraction ring 105 gradually increases. The adjusting spring 110 is compressed. Under the extrusion of the adjusting spring 110, the pressure exerted by the horizontal support plate 106 on the hollow hot pressing roller 107 increases, which is convenient for hot pressing filter cloth with different thicknesses.

[0035] During the hot pressing operation, the winding roller 301 rotates continuously, winding the hot pressed filter cloth around the circumferential side surface of the winding roller 301. At the same time, as the filter cloth wound around the circumferential side surface of the winding roller 301 gradually increases, the pressing limit plate 303 is gradually extruded and moves upward, and the second return spring 304 is extruded to keep the winding of the filter cloth by the winding roller 301 compact.
