Through standardized operation, the distance between the pressing roller and the conveyor belt can be quickly and accurately adjusted to meet the compaction requirements of rock wool fibers of different sizes. At the same time, it can also reduce downtime and improve the overall efficiency of the production line. At the same time, the push plates on both sides move to squeeze the rock wool fibers, and the rock wool fibers are squeezed more tightly.

[0016] (2) In the unloading control device of the rock wool production line, when the operator pushes the handle to reset, the contact plate provides support for the sliding plate. The additional thrust and support reduce the force required by the operator to push the handle, thereby reducing the physical burden of the operator.

The intermittent vibration transmitted by the rectangular sheet reduces the interference of the rock wool fibers adhering to the cylindrical rod on its normal movement, effectively improving the movement smoothness of the cylindrical rod. At the same time, the position of the connecting plate is changed so that the cylindrical rod moves upward without contacting the groove of the linkage plate. The position of the connecting plate is adjusted through standardized operation so that the rectangular sheet can stop moving when it is not needed, thereby reducing unnecessary wear and improving the applicability of the rectangular sheet under different working conditions.

[0025] When the present embodiment is working, the unloading mechanism 5 is started, and the unloading mechanism 5 evenly puts the rock wool fibers onto the top of the conveyor belt 3, and the driving motor 4 is started, and the output end of the driving motor 4 drives the transmission roller 2 to rotate, and the transmission roller 2 rotates to drive the conveyor belt 3 to rotate, and the conveyor belt 3 rotates to drive the rock wool fibers to move, and the servo motor 9 is started, and the output end of the servo motor 9 drives the pressing roller 8 to rotate, and the pressing roller 8 contacts the moving rock wool fibers during rotation, so that the pressing roller 8 rotates to compact the rock wool fibers, and at the same time, the pressing roller 8 rotates to drive the gate-shaped rod 13 to rotate, and the spherical surface of the gate-shaped rod 13 is in intermittent contact with the arc surface of the abutment plate 16 during rotation, and the spherical surface squeezes the rock wool fibers during rotation. The first arc surface, the push plate 16 is squeezed and moves in the direction away from the mounting frame 6. The movement of the push plate 16 drives the push plate 14 to move in the direction away from the mounting frame 6. The push plate 14 stretches the second spring 15 during the movement. The second spring 15 is stretched and deformed. At the same time, the push plate 14 contacts the rock wool fiber during the movement, so that the push plates 14 on both sides move and squeeze the rock wool fiber. The rock wool fiber is squeezed more tightly. When the spherical surface 1 continues to move and separates from the first arc surface, the deformed second spring 15 recovers and drives the push plate 14 to move in the direction of the mounting frame 6.

[0026] See also Figure 1-Figure 9On the basis of the above embodiment, another embodiment of the present invention further includes a protective device and an auxiliary device; the protective device includes a hollow plate 171, a lifting plate 172, a No. 3 spring 173, a contact plate 174, a cylindrical rod 175, a rubber block 176, a No. 1 spring 177, a C-shaped frame 178 and a plurality of friction plates 179, the hollow plate 171 is fixedly penetrated through the surface of the mounting frame 6, the lifting plate 172 is slidably installed inside the hollow plate 171, the No. 3 spring 173 is arranged between the lifting plate 172 and the hollow plate 171, the contact plate 174 is fixedly installed on the side of the lifting plate 172 away from the pressure roller 8, and the contact plate 174 slides through the hollow plate 17 1, a cylindrical rod 175 is fixedly mounted on a side of the lifting plate 172 away from the servo motor 9, the cylindrical rod 175 slides through the inner and outer walls of the hollow plate 171, a rubber block 176 slides through the inner and outer walls of the cylindrical rod 175, a No. 1 spring piece 177 is arranged between the rubber block 176 and the cylindrical rod 175, a C-shaped frame 178 is fixedly mounted on a side of the hollow plate 171 away from the servo motor 9, a plurality of friction plates 179 are fixedly mounted on the inner wall of the C-shaped frame 178, and the contact plate 174 contacts with the bottom of the sliding plate 10, and the additional thrust reduces the force required by the operator to push the handle 12, thereby reducing the physical burden of the operator.

[0027] The rubber block 176 has an arc surface 2 on one side away from the first spring piece 177, and the friction plate 179 has corrugations on one side close to the rubber block 176. The contact plate 174 applies additional resistance to the downward moving sliding plate 10, effectively slowing down the downward movement speed of the sliding plate 10, thereby reducing the risk of collision between the placement plate 7 and the mounting frame 6 due to an unexpected situation.

[0028] The auxiliary device includes a connecting plate 181, a telescopic rod 182, a linkage plate 183, a plurality of rectangular pieces 184, a rotating shaft 185, an arc piece 186, a limiting rod 187 and a second spring piece 188. The connecting plate 181 slides through the surface of the mounting frame 6, the telescopic rod 182 slides through the inner and outer walls of the connecting plate 181, the linkage plate 183 is fixedly mounted on the bottom of the telescopic rod 182, a plurality of rectangular pieces 184 are fixedly mounted on the circumferential surface of the telescopic rod 182, and the rotating shaft 185 rotates It is installed on the inner wall of the connecting plate 181, the arc-shaped piece 186 is fixedly installed on the circumferential surface of the rotating shaft 185, the limiting rod 187 slides through the inner and outer walls of the connecting plate 181, the second spring piece 188 is arranged between the limiting rod 187 and the connecting plate 181, and a groove is provided at the bottom of the linkage plate 183. The intermittent vibration transmitted by the rectangular piece 184 reduces the interference of the rock wool fibers adhering to the cylindrical rod 175 on its normal movement, thereby effectively improving the movement smoothness of the cylindrical rod 175.

[0029] A curved surface 3 is provided on one side of the rectangular piece 184 close to the arc-shaped piece 186, and a spiral spring is provided between the rotating shaft 185 and the connecting plate 181. By providing the spiral spring, it is ensured that the arc-shaped piece 186 can quickly return to its original position after rotation and collide with the rectangular piece 184 to generate vibration, which helps to ensure stable operation.

[0030] The side of the limiting rod 187 close to the mounting frame 6 is adapted to the size of the limiting groove, and the limiting rod 187 contacts the inner wall of the limiting groove. The position of the connecting plate 181 is adjusted through standard operation so that the rectangular piece 184 can stop moving when not in use, thereby reducing unnecessary wear.

[0031] When the present embodiment is working, when the sliding plate 10 moves upward, the sliding plate 10 gradually reduces the pressure applied to the contact plate 174, so that the stretched No. 3 spring 173 begins to recover, and the recovery of the No. 3 spring 173 drives the lifting plate 172 to move upward, and the movement of the lifting plate 172 drives the contact plate 174 to move upward, and the movement of the contact plate 174 applies an additional thrust to the bottom of the sliding plate 10, so that the operator can save more effort when pushing the grip rod 12 upward. At the same time, the movement of the lifting plate 172 drives the cylindrical rod 175 to move upward, and the movement of the cylindrical rod 175 drives the rubber block 176 to move upward. The arc surface 2 of the rubber block 176 contacts the corrugations of the multiple friction plates 179 during the movement. When in contact, The friction plate 179 squeezes the moving rubber block 176, and the rubber block 176 is squeezed and moves toward the cylindrical rod 175. The rubber block 176 squeezes the No. 1 spring sheet 177 during the movement, and the No. 1 spring sheet 177 is squeezed and deformed. The deformed No. 1 spring sheet 177 exerts a reaction force on the rubber block 176, so that the arc surface 2 is in close contact with the corrugation. The arc surface 2 continues to move and generates friction with the corrugation. The speed of the rubber block 176 is slowed down by the influence of the additional resistance, so that when the operator pushes the handle 12 to reset, the contact plate 174 provides support for the sliding plate 10. The additional thrust and support reduce the force that the operator needs to apply when pushing the handle 12, thereby alleviating the operator's The support provided by the contact plate 174 makes the grip 12 more stable when resetting. When the sliding plate 10 moves downward, the sliding plate 10 drives the contact plate 174 to move downward. The movement of the contact plate 174 drives the lifting plate 172 to move downward. The lifting plate 172 stretches the No. 3 spring 173 during the movement. The No. 3 spring 173 is deformed by the stretching. The deformed No. 3 spring 173 applies a reaction force to the lifting plate 172. The lifting plate 172 transmits the reaction force to the moving contact plate 174. The contact plate 174 is affected by the reaction force and causes additional resistance to the moving sliding plate 10. The speed of the sliding plate 10 is slowed down by the influence of the additional resistance. When the lifting plate 172 moves, the cylindrical rod 175 moves downward, and the cylindrical rod 175 moves downward, and the rubber block 176 moves downward. The arc surface 2 of the rubber block 176 contacts the corrugations of the multiple friction plates 179 during movement. The rubber block 176 repeats the above movement and generates friction with the friction plates 179, so that the rubber block 176 applies intermittent resistance to the moving cylindrical rod 175, thereby effectively slowing down the speed of the sliding plate 10 moving downward. The contact plate 174 applies additional resistance to the sliding plate 10 moving downward, effectively slowing down the downward movement speed of the sliding plate 10, thereby reducing the risk of collision between the placement plate 7 and the mounting frame 6 due to unexpected conditions, and effectively improving the safety of the operation. When the cylindrical rod 175 moves upward, the circumferential surface of the cylindrical rod 175 contacts the groove of the linkage plate 183, so that the cylindrical rod 175 moves to drive the linkage plate 183 to move upward, the linkage plate 183 moves to drive the telescopic rod 182 to move upward, the telescopic rod 182 moves to drive the rectangular piece 184 to move upward, and the arc surface 3 of the rectangular piece 184 contacts the inner concave surface of the arc piece 186 during the movement, so that the rectangular piece 184 moves to drive the arc piece 186 to rotate upward, and the arc piece 186 rotates to drive the rotating shaft 185 to rotate upward, and the rotating shaft 185 stretches the volute spring during the rotation, and the volute spring is stretched and deformed, and at the same time, the volute spring is deformed on itself. Energy is stored under the action of elasticity. When the rectangular sheet 184 and the arc-shaped sheet 186 are separated, the deformed scroll spring is restored to drive the rotating shaft 185 to rotate downward. The rotating shaft 185 rotates and drives the arc-shaped sheet 186 to rotate downward. The arc-shaped sheet 186 collides with the second rectangular sheet 184 during rotation to generate vibration. The rectangular sheet 184 contacts with multiple arc-shaped sheets 186 during movement, so that the rectangular sheet 184 collides with multiple arc-shaped sheets 186 to generate intermittent vibration. The rectangular sheet 184 then transmits the vibration to the cylindrical rod 175, so that the cylindrical rod 175 is affected by the intermittent vibration and moves more smoothly. The intermittent vibration transmitted by the rectangular sheet 184 reduces The rock wool fibers adhered to the cylindrical rod 175 interfere with its normal movement, effectively improving the smoothness of the movement of the cylindrical rod 175 and reducing the wear caused by friction. The operator does not need to pull the limit rod 187 to move away from the mounting frame 6 when the rectangular sheet 184 collides with the arc sheet 186. The limit rod 187 stretches the second spring sheet 188 during the movement, and the second spring sheet 188 is deformed due to the stretching. At the same time, the limit rod 187 is separated from the contact surface of the limit groove during the movement, so that the limit of the connecting plate 181 is released, pushing the limit rod 187 to move upward, and the movement of the limit rod 187 drives the connecting plate 181 to move upward. The movement of 181 drives the telescopic rod 182 to move upward, and the movement of the telescopic rod 182 drives the linkage plate 183 to move upward. When the connecting plate 181 moves to the predetermined position, it pushes the limiting rod 187 to move toward the direction of the mounting frame 6. The limiting rod 187 contacts the inner wall of the limiting groove during the movement, so that the connecting plate 181 is limited and cannot move. At the same time, the cylindrical rod 175 does not contact the groove of the linkage plate 183 when moving upward. The position of the connecting plate 181 is adjusted by standard operation, so that the rectangular piece 184 can stop moving when it is not needed, thereby reducing unnecessary wear and improving the applicability of the rectangular piece 184 under different working conditions.
