The control terminal is electrically connected to the raw material stirring device body and the forward and reverse motors and is controlled in a correlated manner. In the initial state, the electric cylinder is in an extended state and the movable support plate is located at the top of the threaded rod. The rubber delivery tube is squeezed by the pressure plates on both sides so that the two sides of the rubber delivery tube are tightly attached to each other, preventing the raw material for paper-faced gypsum production from falling from the rubber delivery tube during the stirring process.

[0028] Specifically: the raw material stirring device body 1 is a raw material stirring device commonly used in paper-faced gypsum production, and its internal structure will not be described in detail here.

[0029] In one embodiment, the extrusion assembly 2 includes a rubber delivery tube 201 and four threaded rods 204. A plurality of bolts and nuts 202 are movably embedded inside the top and bottom of the rubber delivery tube 201. The plurality of bolts and nuts 202 are relatively divided into a group. The surfaces of the eight groups of bolts and nuts 202 are movably covered with a tightening plate 203, and one side of the eight tightening plates 203 is tightly fitted to the surface of the rubber delivery tube 201.

[0030] Specifically: When the bolts and nuts 202 are tightened, the pressing plate 203 can squeeze the rubber conveying tube 201, so that the rubber conveying tube 201 is close to the surface of the discharge port 103 and the filter frame 107, preventing the raw materials from flowing out from the gap between the discharge port 103 and the rubber conveying tube 201 or the filter frame 107 and the rubber conveying tube 201.

[0031] In one embodiment, the bottom ends of the four threaded rods 204 are connected to forward and reverse motors 205, and the output ends of the four forward and reverse motors 205 are fixedly connected to the center of the bottom ends of the four threaded rods 204.

One side of the two movable support plates 206 is fixedly connected to two electric cylinders 207. The four electric cylinders 207 are grouped into two, and the other ends of the two groups of electric cylinders 207 are fixedly connected to a pressure plate 208. The surface of the four forward and reverse motors 205 is fixedly connected to one side of the four support rods 110.

[0032] Specifically, the rubber delivery tube 201 is made of rubber and can be deformed when subjected to force.

[0033] In one embodiment, the filter limit assembly 3 includes a filter plate 301 and four fixed boxes 302, the top and bottom surfaces of the four fixed boxes 302 are penetrated by limit block slots 303, both ends of one side of the inner part of the four fixed boxes 302 are fixedly connected to limit rods 304, two of the eight limit rods 304 are in a group, and the surfaces of the four groups of limit rods 304 are movably sleeved with T-shaped filter plate stop rods 305, and the surfaces of the eight limit rods 304 are sleeved with springs 306, two of the eight springs 306 are in a group, one end of the four groups of springs 306 is fixedly connected to one side of the inner part of the four fixed boxes 302, and the other end of the four springs 306 is fixedly connected to one side of the four T-shaped filter plate stop rods 305, two of the eight limit block slots 303 are in a group, and the interiors of the four groups of limit block slots 303 are movably embedded with limit blocks 307, and the surface of the top of one end of the four T-shaped filter plate stop rods 305 is close to the bottom of the filter plate 301.

[0034] Specifically, the two sides of the bottom of the limiting block 307 are of different lengths, so that the bottom of the limiting block 307 can be inserted into one side of the T-shaped filter plate blocking rod 305 and the interior of the fixed box 302.

[0035] In one embodiment, the surfaces of multiple bolts and nuts 202 are movably embedded in the interior of multiple bolt holes 104, and the surfaces of multiple bolts and nuts 202 are movably embedded in the interior of multiple bolt holes 109. The surfaces inside the top and bottom of the rubber conveying tube 201 are in close contact with the surfaces around the discharge port 103 and the filter frame 107, and the surfaces at both ends of the four threaded rods 204 are correspondingly embedded in the interior of the eight support blocks 111 through bearings.

[0036] Specifically, the forward and reverse motor 205 is fixed on the surface of the support rod 110 to prevent the forward and reverse motor 205 from shaking during operation, thereby affecting the normal operation of the device.

[0037] In one embodiment, four fixed boxes 302 are grouped into two, one end of the two groups of fixed boxes 302 is fixedly connected to both sides of the filter frame 107, the surfaces of the four T-shaped filter plate baffles 305 are movably embedded in the inside of the four baffle movable grooves 108, eight limiting rods 304 are grouped into four, the other ends of the two groups of limiting rods 304 are fixedly connected to the surfaces on both sides of the filter frame 107, and the surface of the filter plate 301 is movably embedded in the inside of the filter frame 107.

[0038] Specifically: the opening of the movable groove 108 of the baffle is slightly larger than the surface of one end of the T-shaped filter plate baffle 305 and smaller than the other end of the T-shaped filter plate baffle 305, which is convenient for limiting the movement of the T-shaped filter plate baffle 305 and preventing the T-shaped filter plate baffle 305 from completely detaching from the inside of the fixed box 302.

[0039] Working principle: The raw material stirring device for paper-faced gypsum production is connected to an external power supply device, which is electrically connected to the raw material stirring device body 1, the control terminal 101 and the forward and reverse motor 205 and provides power. The control terminal 101 is electrically connected to the raw material stirring device body 1 and the forward and reverse motor 205 and is controlled in an associated manner. In the initial state, the electric cylinder 207 is in an extended state and the movable support plate 206 is located at the top of the threaded rod 204. The rubber conveying tube 201 is squeezed by the pressure plates 208 on both sides so that the two sides of the rubber conveying tube 201 are tightly attached to each other, preventing the raw materials for paper-faced gypsum production from falling out of the rubber conveying tube 201 during the mixing process. The stirring device inside the raw material stirring device body 1 is started through the control terminal 101, and the raw materials for paper-faced gypsum production to be stirred are put into the material inlet 102. The stirring device stirs the raw materials inside the raw material stirring device body 1. After the stirring is completed, the stirring device is stopped by the control terminal 101. The forward and reverse motor 205 is started through the control terminal 101. The output end of the forward and reverse motor 205 drives the threaded rod 204 to rotate. Since the movable support plate 206 is threadedly connected to the threaded rod 204, the movable support plate 206 moves downward following the rotation of the threaded rod 204. After the movable support plate 206 moves to the bottom of the threaded rod 204, After the control terminal 101 controls the electric cylinder 207 to shorten, it controls the start of the forward and reverse motor 205 to reverse, so that the movable support plate 206 moves to the initial position and then controls the start of the electric cylinder 207 to extend to the initial state, and repeats the above operation. This design speeds up the discharge of raw materials after the mixing is completed and improves the production efficiency. In the initial state, the spring 306 is in an extended state. When the filter plate 301 needs to be cleaned, the limit block 307 embedded in the limit block slot 303 can be pulled out. After one end of the T-shaped filter plate stopper 305 loses the extrusion limit of the limit block 307, it moves toward the inside of the fixed box 302 under the action of the elastic force of the spring 306. The bottom of the filter plate 301 is no longer limited by the T-type filter plate stop rod 305 and falls from the inside of the filter frame 107. During installation, the filter plate 301 is placed inside the filter frame 107 and its position is higher than the stop rod movable groove 108. The electric cylinder 207 is inserted into the limit block slot 303. One end of the T-type filter plate stop rod 305 is squeezed by the limit block 307 and moves outward from the inside of the fixed box 302. The spring 306 is deformed under the force. After the filter plate 301 is released, the bottom of the filter plate 301 is restricted by the T-type filter plate stop rod 305 and cannot fall. This design facilitates the installation and disassembly of the filter plate 301.

[0040] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
