Description

Technical Field

[0001] This utility model relates to the field of stone processing equipment technology, specifically to the breaking mechanism of a stone unloading machine. Background Technology

[0002] In the processing of natural stone slabs, a whole rubble needs to be cut into multiple slabs. These slabs are usually connected at the bottom and then transported to the unloading station for separation. The traditional unloading process is as follows: first, a stone slab breaking mechanism breaks the connecting part at the bottom of the slab, and then stone slab suction cups pick up the separated slabs and transport them to the subsequent conveyor line. The breaking mechanism and the suction cup device are usually integrated on the same rotating frame, with the suction cups serving as the connecting point for the stone slabs.

[0003] However, the existing technology has obvious drawbacks: First, the stone slab suction cup needs to complete multiple processes such as adsorption, transfer and release, and the system process is complex and has a low fault tolerance rate; Second, the suction cup components are prone to wear and tear due to long-term contact with the edges of the stone, and their reliability is insufficient. Once a failure occurs, the stone slab breaking mechanism will also be unable to work, which will seriously affect production efficiency.

[0004] Based on the above, this utility model proposes a breaking mechanism for a stone unloading machine, which can effectively solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a breaking mechanism for a stone unloading machine. This invention is installed independently on the stone unloading machine and operates independently, without affecting production efficiency.

[0006] This utility model embodiment provides a breaking mechanism for a stone unloading machine, including a liftable breaking component and a relative motion device. The liftable breaking component is arranged to correspond to the gap between two vertical stone slabs. The relative motion device causes the vertical stone slab at the processing position to move relative to the breaking component, so as to break the connection between the vertical stone slab at the processing position and its lower end.

[0007] In one embodiment, the relative motion device includes a drive device, with the stone to be processed placed above the drive device.

[0008] In one embodiment, both ends of the broken component are connected to a front-to-back displacement mechanism, and are further connected to an up-and-down displacement mechanism through the front-to-back displacement mechanism.

[0009] In one embodiment, both the front-to-back displacement mechanism and the up-to-down displacement mechanism are mounted on a support frame.

[0010] In one embodiment, the breaking mechanism further includes several limit sensors.

[0011] In one embodiment, the broken component is positioned above the upright stone slab.

[0012] In one embodiment, the breaking component includes a connecting beam and an insert plate, the insert plate being disposed on the connecting beam, and the connecting beam being connected to the front-to-back displacement mechanism.

[0013] In one embodiment, the forward and backward displacement mechanism includes a first movable cylinder, a first slide rail, a first connecting plate, and a first slider disposed on the broken component. The first slide rail is disposed on the first connecting plate, and the first connecting plate is connected to the output end of the first cylinder. The broken component is slidably connected to the first slide rail via the first slider.

[0014] In one embodiment, the up-and-down displacement mechanism includes an up-and-down moving cylinder including a second moving cylinder, a second slide rail, a second connecting plate, and a second slider disposed on the broken component. The second slide rail is disposed on the second connecting plate, and the second connecting plate is connected to the output end of the second cylinder. The front-and-back displacement mechanism is slidably connected to the second slide rail via the second slider.

[0015] The beneficial effects of the breaking mechanism of the stone unloading machine provided in this embodiment of the utility model are as follows:

[0016] 1. This utility model is set up separately on the stone unloading machine and works independently. If the transfer mechanism fails and is repaired, the stone slab will not break and the mechanism will not be able to work, thus improving production efficiency.

[0017] 2. The breaking mechanism of this utility model has diverse designs and precise fracture control: The breaking mechanism uses an insert plate to effectively abut against the stone slab, which can accurately apply force to achieve the fracture at the connection between the stone slab and the bottom, reduce human intervention, and improve the stability and repeatability of fracture control.

Detailed Implementation

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting the present utility model. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting the present utility model.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0026] like Figures 1 to 4 As shown, the breaking mechanism of the stone unloading machine includes a liftable breaking component 4 and a relative motion device. The liftable breaking component 4 is arranged in relation to the gap between two vertical stone slabs 6. The relative motion device causes the vertical stone slab 6 at the processing position to move relative to the breaking component 4, so as to break the connection between the vertical stone slab 6 at the processing position and its lower end.

[0027] The relative motion device includes a drive device 44, on which the stone to be processed is placed. The stone to be processed consists of multiple vertical stone slabs connected at the bottom.

[0028] Both ends of the broken component 4 are connected to the front-to-back displacement mechanism 42, and are further connected to the up-and-down displacement mechanism 43 through the front-to-back displacement mechanism 42.

[0029] Both the front-to-back displacement mechanism 42 and the up-to-down displacement mechanism 43 are mounted on the support frame 1.

[0030] The broken component 4 is positioned above the upright stone slab 6.

[0031] The breaking mechanism 4 also includes several limit sensors 46. In this embodiment, the support frame 1 is provided with two limit sensors 46, which are used to limit the travel of the insert plate 45 in the front-back and up-down directions, respectively, to ensure that the insert plate 45 can be accurately aligned with the stone slab at the processing position.

[0032] The breaking component 4 includes a connecting beam 41 and an insert plate 45. The insert plate 45 is disposed on the connecting beam 41, and the connecting beam 41 is connected to the front and rear displacement mechanism 42.

[0033] The forward and backward displacement mechanism 42 includes a first moving cylinder 421, a first slide rail 422, a first connecting plate 423, and a first slider 424 disposed on the broken component 4. The first slide rail 422 is disposed on the first connecting plate 423, and the first connecting plate 423 is connected to the output end of the first cylinder. The broken component 4 is slidably connected to the first slide rail 422 through the first slider 424.

[0034] The up-down displacement mechanism 43 includes an up-down moving cylinder including a second moving cylinder 431, a second slide rail 432, a second connecting plate 433, and a second slider 434 disposed on the broken component 4. The second slide rail 432 is disposed on the second connecting plate 433, and the second connecting plate 433 is connected to the output end of the second cylinder. The front-back displacement mechanism 42 is slidably connected to the second slide rail 432 through the second slider 434.

[0035] The following section, in conjunction with the working process of the stone unloading machine, further illustrates the structure and technical effects of this utility model.

[0036] After the upright stone slab 6 is pushed to the processing position by the drive device 44, the cutting workpiece 3 (such as the cutting machine 31 or the air hammer 32) begins to cut or knock the bottom of the upright stone slab 6 at the processing position, so that the connection between the lower end of the upright stone slab 6 and the original stone base slab 7 at the processing position is processed from the front into a weak connection that is easy to break. Then, the insert plate 45 moves to the rear and upper part of the upright stone slab 6 at the processing position under the drive of the front and rear displacement mechanism 42, and then moves downward under the action of the up and down displacement mechanism 43 until the insert plate 45 moves downward to the gap between the upright stone slab 6 at the processing position and the upright stone slab behind it.

[0037] At this point, the vertical stone slab 6 can be displaced relative to its lower end in two ways, thus achieving breakage:

[0038] Method 1: The entire stone to be processed is moved in the rear direction by the drive device 44. Since the upper part of the vertical stone slab 6 is restricted by the insert plate and cannot move, the connection part at the lower end of the vertical stone slab 6 is broken.

[0039] Method 2: The insert plate is driven forward by the front and rear displacement mechanism 42. Since the insert plate abuts against the upper part of the vertical stone slab 6, the forward movement of the insert plate will apply a forward thrust to the vertical stone slab 6, causing the connecting part at the lower end of the vertical stone slab 6 to break.

[0040] After the stone slab breaks, it tilts forward and rests on the receiving structure 21 of the slab placement structure 2. At this time, the tilting cylinder in the tilting structure 22 is activated, driving the receiving structure 21 to rotate around the tilting axis 22. When the receiving structure 21 rotates to form a 90° angle with the horizontal plane, the broken stone slab is reliably supported on the surface of the receiving plate 211 or the receiving roller 212; subsequently, the receiving structure 21 continues to rotate to an inclined state with a 10° angle with the horizontal plane, facilitating the slab-picking action of the material handling robot 51 of the feeding mechanism 5.

[0041] At this time, the material handling robot 51 receives the signal, moves down, and uses the suction plate structure 52 or the fork plate to remove the stone slab, which then enters the subsequent sorting or classification process.

[0042] While the stone slab is being removed, the cutting workpiece 3 (such as the cutting machine 31 or the air hammer 32) begins to cut or knock the bottom of the next upright stone slab 6. The operation direction can start from the left or right, forming a continuous operation process, thereby improving the overall unloading efficiency and automation level.
