[0002] Due to the level of sintering technology in brick factories, some brick stacks that have just been fired from the kiln have the upper layer of bricks stuck together with the lower layer of bricks. When moving the upper layer of bricks, it is necessary to move the upper layer of bricks first to separate it from the lower layer of bricks.

[0003] At present, the previous layer of bricks is usually moved one by one manually, which is time-consuming, inefficient, requires a large number of workers, and has high work intensity, which cannot meet the requirements of large-scale brick making. Utility Model Content

When clamping the upper layer of bricks, the lower clamping mechanism first operates to clamp the lower layer of bricks, and then the upper clamping mechanism clamps the upper layer of bricks, so that the upper and lower layers of bricks change from an adhered state to a separated state. The lower clamping mechanism is then released, and the stacking device then transports the clamping mechanism and the upper layer of bricks to the next process. The upper clamping mechanism then operates to release the upper layer of bricks to the next process. Compared with the prior art, the lower clamping mechanism automatically clamps the lower layer of bricks before clamping the upper layer of bricks, separating the upper and lower layers of bricks. This not only greatly reduces time consumption and greatly improves work efficiency, but also requires fewer operators, significantly reducing production costs, and is suitable for large-scale brick making operations.

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] like Figure 1-Figure 3 As shown together, an anti-adhesion clamping device includes: a frame 1, at least one clamping unit is provided on the frame 1, the clamping unit includes an upper clamping mechanism for clamping the upper layer of bricks and a lower clamping mechanism for clamping the lower layer of bricks;

[0027] The lower clamping mechanism includes a lower clamping cylinder 21 and two sets of lower clamping assemblies arranged opposite to each other along the X-axis direction. The lower clamping assembly includes a clamping rod 22 and two connecting rod mechanisms arranged opposite to each other along the Y-axis direction. The connecting rod mechanism includes a first connecting rod 23 and a second connecting rod 24 that are hingedly connected. The first connecting rod 23 is hinged to the frame 1, and the clamping rod 22 is connected between the two second connecting rods 24.

[0028] The lower clamping cylinder 21 is hinged between two second connecting rods 24 that are oppositely arranged along the X-axis direction.

[0029] When transporting the previous layer of bricks, the frame 1 is connected to the stacking device, and the stacking device drives the two clamping rods 22 to move on both sides of the next layer of bricks. The lower clamping cylinder 21 retracts to drive the two clamping rods 22 to move synchronously and approach each other, so that the two clamping rods 22 clamp the lower layer of bricks, and then the upper clamping mechanism is actuated to clamp the upper layer of bricks, and the state of adhesion with the previous layer of bricks is changed to a separation state, and then the lower clamping cylinder 21 is extended to drive the two clamping rods 22 to move synchronously and away from each other, and then the anti-adhesion clamping device of the utility model is driven by the stacking device to move to the next process, and the upper clamping mechanism is actuated to release the clamped upper layer of bricks to the next process.

[0030] like Figure 4 As shown, the first connecting rod 23 and the second connecting rod 24 are connected by a hinge shaft 25, which is mounted on a hinge seat 26. The hinge seat 26 is provided with an arcuate hole 261 surrounding the hinge shaft 25. The first connecting rod 23 is provided with a limiting post 231, which is located in the arcuate hole 261. When the first connecting rod 23 and the second connecting rod 24 move relative to each other, the limiting post 231 moves in the arcuate hole 261, thereby limiting the range of motion of the first connecting rod 23 and the second connecting rod 24.

[0031] A guide plate 11 is fixed to the frame 1, and a vertical guide groove 12 is provided on the guide plate 11. The first connecting rod 23 is located in the guide groove 12. The guide groove 12 is used to constrain the movement of the first connecting rod 23, so that the first connecting rod 23 moves in the vertical plane to prevent the connecting rod mechanism from deflecting.

[0032] The speed of inflation and deflation of the lower clamping cylinder 21 is regulated by the speed regulating valve 27, and the speed regulating valve 27 can control the softness of the movement of the lower clamping cylinder 21 to prevent the clamping rod 22 from breaking the bricks when the lower clamping cylinder 21 moves too fast.

[0033] The upper clamping mechanism includes two opposing clamping plates 31 and an upper clamping cylinder 32 connected between the two clamping plates 31. The two clamping plates 31 move along the X-axis via a guide mechanism. Along the Y-axis, the clamping plates 33 are mounted on the clamping plates 31, positioned above the clamping rod 22. To clamp the upper layer of bricks, after the lower clamping mechanism has clamped the next layer, the upper clamping cylinder 32 retracts, driving the two clamping plates 31 closer together. This allows the clamping plates 33 on the two clamping plates 31 to move closer together, clamping the upper layer of bricks. Two upper clamping cylinders 32 are provided, each controlled by an upper clamping cylinder solenoid valve 35.

[0034] To ensure consistent and precise movement of the two clamping plates 31, a synchronous motion mechanism is installed between the two clamping plates 31. This mechanism includes two racks 34 fixed to each clamping plate 31 and a gear meshing with the two racks 34. When the two clamping plates 31 move, the two racks 34 move synchronously with them. Driven by the gears, the two racks 34 move synchronously, forcing the two clamping plates 31 to move synchronously. As a result, the clamping plates 33 on the two clamping plates 31 move synchronously, resulting in precise movement and accurate clamping position.

[0035] In order to improve the stacking efficiency of bricks, a clamping unit includes a lower clamping mechanism and two upper clamping mechanisms. The lower clamping mechanism first clamps the next layer of bricks, and then the two upper clamping mechanisms clamp the upper layer of bricks.

[0036] Different brick stacks require different clamping units. In the illustrated embodiment, two clamping units are provided, one with a large pitch and the other with a small pitch. The distance between the two opposing clamping rods 22 in the large pitch clamping unit is greater than the distance between the two opposing clamping rods 22 in the small pitch clamping unit. The distance between the two opposing clamping plates 33 in the large pitch clamping unit is greater than the distance between the two opposing clamping plates 33 in the small pitch clamping unit. In other embodiments, both clamping units may be large pitch clamping units or small pitch clamping units.

[0037] Each clamping unit is equipped with a brick stack height detection device 4. If there are two clamping units, they are arranged side by side, and the two brick stack height detection devices 4 are arranged diagonally. The height of each layer of bricks lowered by the clamping device is detected by the brick stack height detection device 4. The brick stack height detection device 4 is placed diagonally, which can effectively detect the height of each layer of bricks at two different positions, preventing the unloading clamp from colliding with the brick stack during unloading. The brick stack height measured in this way is the actual brick stack height, avoiding the risk of clamping too high or too low due to the inaccurate method of subtracting the height of the brick group layer by layer.

[0038] The above are examples of the best embodiments of the present invention. Any parts not described in detail are common knowledge of those skilled in the art. The scope of protection of the present invention is based on the content of the claims. Any equivalent transformation based on the technical teachings of the present invention is also within the scope of protection of the present invention.
