Description

Technical Field

[0001] The utility model relates to the technical field of rock slab production, in particular to a pressing device for laminating rock slabs. Background Art

[0002] The existing rock slabs require pressing equipment during the processing process, and the raw materials are pressed into pressed plates through the pressing equipment.

[0003] A search revealed a Chinese patent document that discloses a device for pressing and forming inorganic rock slabs [Application Number: CN202222802938.8]. This device comprises an annular plate, a U-shaped plate fixed to one side wall of the annular plate, a first cylinder fixed to the top center of the annular plate, a pressing plate provided inside the annular plate, an output end of the first cylinder passing through the top of the annular plate and fixedly connected to the top of the pressing plate, a pressing groove provided on the bottom inner wall of the annular plate, and a groove provided on one inner wall of the pressing groove near the top.

[0004] The device disclosed in this patent serves to facilitate the demolding of the formed rock slab when in use, thereby achieving the effect of automatic demolding. However, when the device pushes the rock slab to one side of the U-shaped plate, there is a certain height difference between the bottom of the U-shaped plate groove and the rock slab discharge position. This causes the rock slab to fall directly to the bottom of the U-shaped plate groove, resulting in a lack of a supporting structure for the rock slab, resulting in damage or even breakage, which affects the processing quality of the rock slab after pressing and increases the loss during the pressing process of the pressing plate.

The upper surface of the pressing base 1 is fixedly connected to the second cylinder 7, and one end of the telescopic rod of the second cylinder 7 is fixedly connected to the connecting plate 8. A pushing plate 9 is fixedly connected to the side surface of the connecting plate 8 facing the mold groove 4, and a blanking base 10 is fixedly installed on the side surface of the pressing base 1 away from the second cylinder 7. The blanking base 10 is U-shaped, and the rock slab in the mold groove 4 after pressing is completed can be pushed out of the mold groove 4 through the discharge plate 5, and the setting of the pushing plate 9 can push the rock slab pushed out by the discharge plate 5 into the blanking base 10, thereby completing the automatic discharge after the rock slab is pressed.

[0023] The interior of the blanking base 10 is hollow, and a receiving plate 11 is slidably connected in the groove of the blanking base 10. A push rod 18 is fixedly installed on the lower surface of the receiving plate 11. The lower end of the push rod 18 slides through the blanking base 10, and the lower end of the push rod 18 is fixedly connected to a fixed plate 19. A first rack 21 is fixedly installed on both sides of the fixed plate 19. The first rack 21 is meshed with a gear 20 on the side facing the pressing base 1. One side of the gear 20 is rotatably connected to the inner wall of the blanking base 10 through a rotating shaft. The side of the gear 20 away from the first rack 21 is meshed with a second rack 22. The surface of the second rack 22 facing away from the gear 20 is fixedly connected to a sliding sleeve 24. The sliding sleeve 24 is provided with a sliding sleeve. There is a vertical slide bar 23, and the upper and lower ends of the vertical slide bar 23 are respectively fixedly mounted on the upper and lower inner walls of the blanking base 10. A tension spring 25 is fixedly connected between the upper surface of the sliding sleeve 24 and the top wall of the blanking base 10. The tension spring 25 is movably sleeved on the outer surface of the vertical slide bar 23. When in use, the second rack 22 moves downward, so that the first rack 21 moves upward under the meshing transmission of the gear 20, so that the push rod 18 pushes the receiving plate 11 to move upward, so that the rock slab pushed out by the pushing plate 9 can be received, and the problem of the rock slab falling directly into the groove of the blanking base 10 and being broken or even broken is avoided as much as possible, further ensuring the quality of the rock slab after pressing and reducing the loss during the rock slab pressing process.

[0024] The upper surface of the pressing base 1 is provided with two connecting grooves 13, and the two connecting grooves 13 are respectively located on both sides of the mold groove 4 and are connected to the inside of the pressing base 1. A limiting slide 15 is fixedly connected between the inner walls on both sides of the connecting groove 13. A push plate 14 is provided on the sliding sleeve of the limiting slide 15. The upper side of the push plate 14 extends out of the upper surface of the pressing base 1, and the lower side extends into the pressing base 1. The upper side of the push plate 14 contacts the connecting plate 8, and the lower side of the push plate 14 is hinged with a rotating push plate 17. The inner wall of the pressing base 1 is provided with two connecting grooves 13, both of which are connected to the drop The through slot 16 is connected to the inside of the material base 10, and the other side of the rotating push plate 17 extends into the blanking base 10 through the through slot 16 and is hinged to the sliding sleeve 24. In this way, when the push plate 14 slides on the limiting slide bar 15, the rotating push plate 17 can form a downward thrust on the sliding sleeve 24, so that the sliding sleeve 24 synchronously drives the second rack 22 to move downward. When the pushing plate 9 pushes out the rock plate, the receiving plate 11 can be automatically controlled to move upward. No manual operation is required, which reduces the workload of the staff. At the same time, the structure can be completed with a simple linkage structure and has high stability.

[0025] A contact plate 12 is provided on the upper side of the receiving plate 11, and a number of compression springs 26 are fixedly connected between the contact plate 12 and the receiving plate 11. When in use, the rock plate first falls onto the contact plate 12. At the same time, the compression springs 26 will form a certain buffer for the impact force of the pressure plate falling, further providing better protection for the rock plate.

[0026] More preferably, a protrusion may be added to the top of the contact plate 12 so that there is a certain gap between the pressure plate and the contact plate 12, which is convenient for workers to carry by forklift or manually.

[0027] Working principle: After the rock plate is pressed and formed by the pressing plate, the pressing cylinder 3 drives the pressing plate to move upward. At this time, the first cylinder 6 is started and pushes the discharge plate 5 to move upward, so that the discharge plate 5 pushes the pressed plate out of the die groove 4 until the upper surface of the discharge plate 5 is flush with the upper surface of the pressing base 1;

[0028] The second cylinder 7 is started, pushing the push plate 9 to move to one side of the blanking base 10, so that the push plate 9 can push the rock plate on the discharge plate 5 to the blanking base 10. In the process of the push plate 9 pushing the rock plate, the two sides of the connecting plate 8 will contact with the push plate 14 and form a thrust on the push plate 14, so that the push plate 14 is displaced to the side close to the blanking base 10. The push plate 14 simultaneously forms a thrust on the rotating push plate 17, and the rotating push plate 17 can form a downward thrust on the sliding sleeve 24, so that the sliding sleeve 24 synchronously drives the second rack 22 to move downward, and at the same time the tension spring 25 is stretched, and the second rack 22 It drives the gear 20 to rotate clockwise, so the first rack 21 moves upward under the meshing transmission of the gear 20, and the push rod 18 pushes the receiving plate 11 to move upward, so that the rock plate pushed out by the pushing plate 9 can be received. When the pushing plate 9 completely pushes out the rock plate, the second cylinder 7 drives the pushing plate 9 to move to the side away from the blanking base 10. At this time, the connecting plate 8 no longer squeezes the pushing plate 14, so the tension spring 25 pulls the second rack 22 to move to the initial position, so that the receiving plate 11 drives the rock plate to slowly descend, and now it is convenient for the staff to carry the rock plate on the receiving plate 11.
