Description

Technical Field

[0001] The utility model relates to the field of stone plate processing equipment, in particular to a continuous production line of a stone plate bridge mill. Background Art

[0002] In stone processing plants, bridge grinders are also common. Bridge grinders generally have only one grinding head, but they can achieve the purpose of polishing a piece of stone slab by changing the rough grinding, fine grinding, and polishing grinding blocks of different coarseness (different mesh sizes) at the same station.

[0003] However, in the current production process, bridge mills basically work as a single machine, without forming an assembly line operation, and the loading and unloading of materials rely on manual handling or cantilevered hanging plates to the workbench for processing, which has the following "pain points":

[0004] 1. Manual loading of panels is extremely laborious and prone to causing work-related accidents, and is also inefficient.

[0005] 2. The cantilever hanging board is easy to fall off and break; it is difficult to control and the safety is very poor.

[0006] 3. For the above two methods of board loading, the workbench generally needs to be made liftable and flippable; that is, when loading the board, the workbench needs to be flipped to a nearly upright state to facilitate board loading; then fall back to a horizontal state. In this way, the repetitive positioning accuracy of the movable workbench is poor, which affects the quality accuracy of the ground board.

[0007] 4. Loading and unloading materials takes a lot of time, which reduces the effective working time of the mill and reduces the actual production efficiency.

[0008] In summary, it is necessary to develop a continuous production line for stone slab bridge mill, by improving the mill working

[0009] The machine is equipped with automatic loading and unloading equipment to form an automatic continuous production line. This greatly increases the effective working time of the mill, drives production efficiency, saves manpower, reduces the labor intensity of operators, improves safety, and solves the pain points in the industry. Utility Model Content

[0010] Therefore, based on the above concept, the utility model proposes a continuous production line of a stone plate bridge mill, which solves the technical problems of short effective working time and low production efficiency of existing stone plate mills.

[0011] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a continuous production line of a stone plate bridge mill, comprising an automatic plate loading machine, a plate feeding transition frame, a grinding plate workbench, a stone plate bridge mill mounted on the grinding plate workbench, a plate discharging transition frame, and an automatic plate unloading machine arranged in sequence, a chain conveying device is arranged on the grinding plate workbench, and the chain conveying device includes a chain, a plate support rod, a sprocket, a driving shaft, a driven shaft, and a driving motor. The number of the chains is two, and the two chains are respectively arranged on both sides of the grinding plate workbench and are parallel to each other. The sprockets are respectively arranged at both ends of the driving shaft and the driven shaft. The chains are wound around the sprockets and mesh with each other on the sprockets, and a number of pads are laid on the grinding plate workbench.

[0012] Furthermore, a gap is provided between two adjacent sleepers and the spacing between each gap is the same.

[0013] Furthermore, a lifting cylinder is arranged on the grinding plate workbench, and the chain conveying device is connected with the lifting cylinder and is lifted up and down by the extension and retraction of the lifting cylinder.

[0014] By adopting the above technical solution, the beneficial effects of the utility model are:

[0015] Compared with the existing stone slab bridge mill, the utility model has the performance of fully automatic assembly line operation and can automatically load and unload materials without relying on manual operation, thus avoiding a series of construction problems caused by manual loading and unloading, such as high labor intensity and dangerous operation.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figure 1-Figure 4 The utility model provides a continuous production line of a stone plate bridge mill, comprising an automatic plate loading machine 1, a plate feeding transition frame 2, a grinding plate workbench 3, a stone plate bridge mill 31 erected on the grinding plate workbench, a plate discharging transition frame 4, and an automatic plate unloading machine 5, which are arranged in sequence. A chain conveyor 6 is arranged on the grinding plate workbench 3, and the chain conveyor 6 comprises a chain 61, a plate support rod 62, a sprocket 63, a driving shaft 64, a driven shaft 65, and a driving motor 66. The number of the chains 61 is two, and the two chains 61 are respectively arranged on both sides of the grinding plate workbench 3 and are parallel to each other. The sprockets 63 are respectively arranged at both ends of the driving shaft 64 and the driven shaft 65. The chains 61 are wound around the sprockets 63 and meshed with each other on the sprockets 63. A plurality of pads 8 are laid on the grinding plate workbench 3, and the specific number of the pads 8 is determined according to the actual length of the grinding plate workbench 3 and the size of the gap between them.

[0023] A gap 81 is provided between two adjacent sleepers 8 and the spacing between each gap 81 is the same.

[0024] The grinding plate workbench 3 is provided with a lifting cylinder 7 , and the chain conveyor 6 is connected to the lifting cylinder 7 and moves up and down driven by the extension and contraction of the lifting cylinder 7 .

[0025] The working mode of the utility model is to drive the chain conveyor device 6 to move up and down by the up and down lifting of the lifting cylinder 7. When the stone slab moves to just above the cushion 8, the lifting cylinder 7 sinks to place the stone slab on the cushion 8 for processing. After completion, the regenerated gas transports the stone slab away from the processing station.
