[0023] In this embodiment: by providing the limiting strip 204 and the limiting groove 205 , the limiting groove 205 limits the limiting strip 204 , so that the limiting strip 204 and the support frame 102 move more stably, thereby making the pressing plate 203 move more stably.

[0024] The limiting mechanism 3 is arranged above the bottom plate 101. The limiting mechanism 3 includes two limiting plates 302 slidably mounted on the top surface of the bottom plate 101. The two limiting plates 302 are respectively fixed with two sliding rods 301 at the sides away from each other. The limiting mechanism 3 is used to limit the two sides of the rock wool board; Specifically, Figure 1-Figure 5 As shown, the other ends of the multiple sliding rods 301 slide through the inner walls on both sides of the support frame 102 and extend to the outside of the support frame 102, one end of the multiple sliding rods 301 is fixedly installed with a circular plate 303, and the outer walls of the multiple sliding rods 301 are slidably installed with an elastic member 304, and the two ends of the multiple elastic members 304 are fixedly connected to the side surfaces of the multiple circular plates 303 and the two side surfaces of the support frame 102.

[0031] In this embodiment, by providing the adjustment slot 311 , when the limiting bar 204 moves downward, the adjustment slot 311 on the limiting bar 204 pushes the adjustment bar 310 to move, thereby driving the fixing block 309 and the connecting plate 307 to move.

[0032] The fixing mechanism 4 is arranged above the conveying assembly 1 , and the fixing mechanism 4 includes a fixing plate 404 located above the bottom plate 101 , a rotating shaft 403 is fixedly mounted on the top surface of one end of the fixing plate 404 , and the fixing mechanism 4 is used to fix the side surface of the rock wool board.

[0034] In this embodiment, the elastic member 2 401 is provided to apply elastic force to the L-shaped plate 306 , so that the L-shaped plate 306 has a continuous thrust, and the elastic force of the elastic member 2 401 is much smaller than the elastic force of the elastic member 1 304 .

[0035] Specifically, Figure 1-Figure 8 As shown, mounting plates 402 are fixedly installed on the top surfaces of both ends of the two limit plates 302, and the upper ends of multiple rotating shafts 403 are rotated through the bearing seats to penetrate the bottom surfaces of multiple mounting plates 402 and extend to the top of the mounting plates 402. Rotating plates 405 are fixedly installed on the upper ends of multiple rotating shafts 403, and cylinders 406 are fixedly installed on the edges of the top surfaces of multiple rotating plates 405.

[0036] In this embodiment: by providing the rotating shaft 403 and the mounting plate 402, the mounting plate 402 fixes the rotating shaft 403 and ensures that the rotating shaft 403 can rotate, and the rotating shaft 403, the rotating plate 405, the cylinder 406 and the fixed plate 404 rotate together.

[0038] In this embodiment: when the movable bar 410 is moved, the through groove 411 on the movable bar 410 cooperates with the arc groove 409 on the disk 408, so that the cylinder 406 rotates a certain angle along the arc groove 409, and the cylinder 406 drives the rotating plate 405, the rotating shaft 403 and the fixed plate 404 to rotate the moving angle, and the fixed plate 404 is at a right angle to the limit plate 302.

[0039] The specific solution is as follows: when the rock wool board is transported to the bottom plate 101 on the conveying assembly 1, the cylinder 201 is turned on to drive the fixing frame 202 and the pressing plate 203 to move downward, the fixing frame 202 drives the limit bar 204 to move, and the two limit bars 204 drive the two adjustment bars 310 to approach each other through the limit groove 205, and the adjustment bar 310 drives the fixing block 309, the connecting plate 307 and the L-shaped plate 306 to move, and the L-shaped plate 306 pushes the elastic member 401 to squeeze and pushes the moving bar 410 to move at the same time, and the moving bar 410 pushes the cylinder 406 to move through the through groove 411, and at the same time, under the cooperation of the arc groove 409, the cylinder 406 rotates a certain angle, and the cylinder 406 drives the rotating plate 40 5. The rotating shaft 403 and the fixed plate 404 rotate at a certain angle, so that the fixed plate 404 limits the two sides of the rock wool board, and then the L-shaped plate 306 continues to push the limiting plate 302 to move a certain angle, and the limiting plate 302 squeezes and fixes the other two sides of the rock wool. There is no need to set up more power components, and the two sides of the rock wool can be limited during pressing, thereby improving the accuracy and quality of pressing and reducing the cost of the enterprise. After the pressing is completed, the pressing plate 203 is restored to its original position. Under the joint action of the elastic member 1 304 and the elastic member 2 401, the limiting plate 302 and the fixed plate 404 are restored to their original positions, and the rock wool board is pushed to the other side of the conveying component 1 for conveying through the pushing component 103.
