Description

Technical Field

[0001] The invention relates to the technical field of rock wool board production, and in particular to a rock wool board sorting and stacking machine. Background Art

[0002] Rock wool board is an ideal insulation material for building exterior wall insulation system. Its raw materials are natural ore and steel-making blast furnace slag. Its production process generally includes the following steps: raw material melting - centrifugal fiberization - surface collection into felt - felt laying and pleating - pressurized curing - cutting - packaging. When packaging rock wool boards, it is necessary to use a stacker to clamp and stack the rock wool boards transported on the belt conveyor, and place the clamped rock wool boards on a transport vehicle for transportation.

[0003] In the prior art, when the stacker clamps and stacks the rock wool boards transported on the belt conveyor, the stacker clamps and fixes the boards through a clamping mechanism on the stacker, and the clamping mechanism generally consists of two clamping plates and a driving mechanism. The rock wool boards transported on the belt conveyor are clamped and fixed through the two clamping plates. During the cutting process of the rock wool boards, the cutting surface of the rock wool boards is uneven due to problems with the rock wool board materials themselves. When the rock wool boards are piled up on the belt conveyor for transportation, the side edges of the piled up rock wool boards are not on the same plane. When the two clamping plates clamp the piled up rock wool boards, a gap is generated between the rock wool board at the lowest end and the clamping plate, and the side edge of the rock wool board at the upper end contacts the clamping plate, resulting in the stacked rock wool boards being clamped and fixed. The rock wool board at the bottom end will fall off during the clamping process, and the rock wool boards stacked on the belt conveyor cannot be completely clamped and fixed. Summary of the invention

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Example 1: Reference Figure 1-4 , a rock wool board sorting and stacking machine comprises a bottom plate 1, a lifting and rotating frame 2 is fixedly connected to the upper end of the bottom plate 1, a slide frame 3 is slidably connected to the lifting and rotating frame 2, a second electric telescopic rod 4 is connected to the lifting and rotating frame 2 for driving the slide frame 3 to move in the horizontal direction, two parallel clamping plates 6 are slidably connected to the slide frame 3, a second servo motor 5 is fixedly connected to the slide frame 3, a bidirectional screw 7 for adjusting the distance between the two clamping plates 6 is connected to the output end of the second servo motor 5, an anti-skid plate 8 is fixedly connected to the opposite side of the two clamping plates 6, a separation mechanism 9 is connected to the opposite side of the two clamping plates 6, and a plugging plate 10 is connected to both sides of each separation mechanism 9, and the plugging plate 10 is located below the anti-skid plate 8, a pointed head 11 is provided at one end of each plugging plate 10, and a mounting groove is opened at the bottom end of each plugging plate 10, and a roller 12 is rotatably connected in each mounting groove, and the bottom end of the roller 12 is lower than the bottom end of the pointed head 11;

[0027] Reference Figure 2 The lifting and rotating frame 2 includes a groove frame 21, which is fixedly connected to the upper end of the bottom plate 1, and a movable plate 22 is slidably connected to the upper end of the groove frame 21. A first electric telescopic rod 23 for driving the movable plate 22 to move in a vertical direction is fixedly connected to the groove frame 21, and a first servo motor 24 is fixedly connected to the movable plate 22. An open box 25 is fixedly connected to the output end of the first servo motor 24, and a second electric telescopic rod 4 is fixedly connected to the open box 25. The open part of the open box 25 is slidably connected to the slide frame 3, and a plurality of movable legs 26 are fixedly connected to the bottom end of the open box 25, and the bottom end of each movable leg 26 is in rolling contact with the upper end of the movable plate 22.

[0028] Working principle:

[0029] The bottom plate 1 is fixed on the ground, and the two clamping plates 6 are located above the ends of the belt conveyor. When the rock wool board moves to the end of the belt conveyor, the first electric telescopic rod 23 drives the movable plate 22 to move downward by a set distance, and the first electric telescopic rod 23 drives the movable plate 22 to move downward, and the movable plate 22 drives the first servo motor 24 to move, and the first servo motor 24 drives the open box 25 to move downward, and the open box 25 drives the slide frame 3 to move, and the slide frame 3 drives the two clamping plates 6 to move downward, and each clamping plate 6 drives the anti-slip plate 8 to move, and at the same time, each clamping plate 6 drives the plugging plate 10 to move downward through the separation mechanism 9, and each plugging plate 10 drives the roller 12 to move downward, and after the clamping plate 6 moves downward by a set distance, the rock wool board is located between the two anti-slip plates 8, and because the bottom end of the roller 12 is lower than the bottom end of the pointed head 11, each roller 12 squeezes the belt of the belt conveyor, and the belt is depressed downward at the pressed position, so that the pointed head 11 is located at the depressed position of the belt;

[0030] After the second servo motor 5 is started, it drives the bidirectional screw 7 to rotate clockwise for a set number of turns. After the bidirectional screw 7 is transferred, the two clamps 6 move toward each other by a set distance. Each clamp 6 drives the plug 10 to move toward the rock wool board by a set distance through the separation mechanism 9. The plug 10 rolls and squeezes the belt of the belt conveyor through the roller 12. When the roller 12 approaches the rock wool board, a gap is generated between the belt and the lower surface of the rock wool board under the squeezing of the roller 12. After the pointed head 11 is inserted into the gap, it is located at the bottom end of the rock wool board. As the distance between the two clamps 6 is gradually shortened, the pointed head 11 is gradually inserted into the gap, so that the two ends of the rock wool board are located on the plug 10. After the two clamps 6 move toward each other by a set distance, the rock wool board is squeezed by two anti-slip plates 8. Several plugs 10 support the four corners of the bottom rock wool board. The rock wool board between the two anti-skid plates 8 is pushed by the insert plate 10 in the vertical direction. When a gap is generated between the side of the rock wool board and the two anti-skid plates 8, the rock wool board between the two anti-skid plates 8 will not fall down under the support of a plurality of insert plates 10, thereby improving the clamping and fixing effect of the rock wool board. The insert plate 10 is in rolling contact with the belt of the belt conveyor through the roller 12, reducing the friction on the belt of the belt conveyor caused by the insert plate 10 when supporting the rock wool board, thereby reducing the wear on the belt of the belt conveyor. At the same time, a gap is generated between the belt and the lower surface of the rock wool board under the extrusion of the roller 12. After the pointed head 11 is inserted into the gap, it is located at the bottom end of the rock wool board. During the process of the pointed head 11 being inserted into the bottom end of the rock wool board, the side of the rock wool board will not be damaged, thereby improving the clamping and supporting effect of the rock wool board.

[0031] After the rock wool board is clamped and fixed, the first electric telescopic rod 23 drives the movable plate 22 to move upward by a set distance, so that the rock wool board is separated from the belt conveyor. The first servo motor 24 starts to drive the open box 25 to rotate by a set angle. The open box 25 rolls with the movable plate 22 through a number of movable legs 26, so that the open box 25 rotates smoothly. The open box 25 drives the chute frame 3 to rotate. The chute frame 3 drives the rock wool board to rotate through the anti-slip plate 8 and the plug plate 10, so that the rock wool board is located above the conveyor vehicle. After the first electric telescopic rod 23 is started, it drives the movable plate 22 to move downward. The two servo motors 5 drive the bidirectional screw 7 to rotate counterclockwise for a set number of turns. After the bidirectional screw 7 is transferred, the two clamping plates 6 move away from each other by a set distance. Each clamping plate 6 drives the anti-skid plate 8 to move, and the anti-skid plate 8 is separated from the rock wool board. At the same time, each clamping plate 6 drives the plug plate 10 to move through the separation mechanism 9. Several plug plates 10 are gradually separated from the rock wool board. After the plug plate 10 is separated from the bottom end of the rock wool board, the rock wool board between the two anti-skid plates 8 falls on the mobile vehicle, and the stacking of the rock wool board is completed.

[0032] Embodiment 2: Each clamping plate 6 drives the plugging plate 10 to move through the separation mechanism 9, and several plugging plates 10 are gradually separated from the rock wool board. After the plugging plate 10 is separated from the bottom end of the rock wool board, the rock wool board between the two anti-slip plates 8 falls on the moving vehicle to complete the stacking of the rock wool board. At the moment when several plugging plates 10 are separated from the bottom rock wool board, since the outer walls of the clamped rock wool board are not in the same plane due to production quality problems, the stacked rock wool boards move downward under their own gravity, and the outer walls of some rock wool boards collide with the end of the pointed head 11. The rock wool board that collides with the end of the pointed head 11 is greatly offset due to the collision, thereby reducing the flatness of the stacking. , referring to Figures 5-7, as another preferred embodiment of the present invention, the difference from Example 1 is that the separation mechanism 9 includes two parallel mounting frames 91, the two parallel mounting frames 91 are fixedly connected to the splint 6, each mounting frame 91 is slidably connected with a movable frame 92, the bottom end of each movable frame 92 is connected to the plug plate 10, a first connecting plate 93 is fixedly connected between the two movable frames 92, a third electric telescopic rod 94 is fixedly connected to the splint 6, the third electric telescopic rod 94 is located between the two mounting frames 91, and one end of the third electric telescopic rod 94 is fixedly connected to the first connecting plate 93.

[0033] Working process:

[0034] When the two clamping plates 6 are located above the belt of the belt conveyor, the third electric telescopic rod 94 drives the first connecting plate 93 to move a set distance in the direction of the clamping plate 6, and the first connecting plate 93 drives the two movable frames 92 to move, and the movable frames 92 move smoothly under the guidance of the mounting frame 91, and each movable frame 92 drives the plugging plate 10 to move, and each plugging plate 10 drives the pointed head 11 to move, so that a plurality of pointed heads 11 are located between the two anti-slip plates 8, and when the rock wool board is clamped and fixed, the pointed head 11 is in contact with the lower surface of the bottommost rock wool board;

[0035] When stacking the rock wool boards on the mobile vehicle, the third electric telescopic rod 94 drives the first connecting plate 93 to move a set distance in the direction away from the splint 6, and the first connecting plate 93 drives the two movable frames 92 to move, and each movable frame 92 drives the plug plate 10 to move, and each plug plate 10 drives the pointed head 11 to move, so that several pointed heads 11 are located under the corresponding splint 6, and the second servo motor 5 drives the bidirectional screw 7 to rotate counterclockwise for a set number of turns. After the bidirectional screw 7 is transferred, the two splints 6 move away from each other by a set distance, and each splint 6 drives the anti-slip plate 8 to move, so that the two anti-slip plates 8 are separated from the rock wool boards. The separated rock wool boards move downward under their own gravity. Since the pointed head 11 is located under the splint 6, the pointed head 11 is staggered with the rock wool board, and the rock wool board will not collide with the pointed head 11 during the downward movement, and the rock wool board falls smoothly on the mobile vehicle, thereby improving the flatness of the stacking of the rock wool boards.

[0036] Embodiment 3: After the tip 11 is retracted under the clamping plate 6, there is a large distance between the rock wool board at the bottom between the two clamping plates 6 and the moving vehicle. When the rock wool board moves downward under its own gravity, the rock wool boards collide with each other and turn, which reduces the stacking effect of the rock wool board. Figure 6-9 As another preferred embodiment of the present invention, the difference from Embodiment 2 is that the bottom end of each clamping plate 6 is connected to a buffer mechanism 13 for improving the flatness of stacking, and the buffer mechanism 13 includes an L-shaped plate 131, which is fixedly connected to the bottom end of the clamping plate 6, and a connecting shaft 132 is fixedly connected to the L-shaped plate 131, and one end of the connecting shaft 132 is rotatably connected to a gear 133, and a mounting plate 134 is fixedly connected between the two movable frames 92, and a first tooth plate 135 is fixedly connected to the mounting plate 134, and the first tooth plate 135 and the gear The wheels 133 are meshed with each other, and a second tooth plate 136 is slidably connected to the L-shaped plate 131. The second tooth plate 136 is meshed with the connected gear 133. One end of the second tooth plate 136 is fixedly connected to a second connecting plate 137. One end of the second connecting plate 137 passes through the mounting plate 134. The other end of the second tooth plate 136 is fixedly connected to a buffer block 139. The buffer block 139 is located between the bottom end of the anti-slip plate 8 and the bottom end of the plug plate 10. An inclined surface is provided on one side of the buffer block 139. One end of the second connecting plate 137 is fixedly connected to an anti-dropping block 138.

[0037] Working principle:

[0038] The third electric telescopic rod 94 drives the first connecting plate 93 to move a set distance in the direction of the clamping plate 6, so that the plurality of pointed heads 11 are located between the two anti-slip plates 8. At the same time, the first connecting plate 93 drives the first tooth plate 135 to move in the direction of the clamping plate 6 through the mounting plate 134. After the first tooth plate 135 moves, it drives the gear 133 to rotate. The gear 133 rotates around the connecting shaft 132. After the gear 133 rotates, it drives the second tooth plate 136 to move away from the clamping plate 6. The second tooth plate 136 moves smoothly under the guidance of the second connecting plate 137. The second tooth plate 136 drives the buffer block 139 to move, so that the buffer block 139 is retracted under the clamping plate 6. The buffer block 139 and the pointed heads 11 are staggered, so that the support of the pointed heads 11 to the rock wool board will not be affected.

[0039] When the third electric telescopic rod 94 drives the first connecting plate 93 to move a set distance in the direction away from the clamping plate 6, several pointed heads 11 are located under the corresponding clamping plates 6. At the same time, the first connecting plate 93 drives the first tooth plate 135 to move in the direction away from the clamping plate 6 through the mounting plate 134. After the first tooth plate 135 moves, it drives the gear 133 to rotate. The gear 133 rotates around the connecting shaft 132. After the gear 133 rotates, it drives the second tooth plate 136 to move in the direction of the clamping plate 6. The second tooth plate 136 moves smoothly under the guidance of the second connecting plate 137. The second tooth plate 136 drives the buffer block 139 to move, so that the buffer block 139 is located at the bottom end of the anti-slide plate 8. The inclined surface of the buffer block 139 is located at the bottom end of the anti-slide plate 8. After the two anti-slide plates 8 are gradually separated from the rock wool board, the rock wool The board falls on the inclined surface of the buffer block 139. As the distance between the two anti-skid plates 8 gradually increases, the distance between the two buffer blocks 139 gradually increases, and the rock wool board between the two buffer blocks 139 slowly slides along the inclined direction of the inclined surface. When the buffer block 139 is separated from the bottom of the inclined surface, the distance between the bottom end surface of the buffer block 139 and the moving vehicle is short, thereby reducing the distance between the rock wool board at the bottom between the two anti-skid plates 8 and the moving vehicle, reducing the time for the rock wool board to fall downward, thereby reducing the spacing between the rock wool boards during the falling process. When the rock wool boards move downward under their own gravity for stacking, the distance between each rock wool board is small, so that the collision strength between each rock wool board is reduced, so that it is not easy to turn, thereby improving the stacking effect of the rock wool boards.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
