Description

Technical Field

[0001] This utility model relates to the technical field of stone processing equipment, specifically to a slab unloading and receiving mechanism for 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; 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, since the suction cup is responsible for the transfer and connection of the unloaded stone slab, the stone slab suction cup needs to complete multiple processes such as adsorption, transfer and release, making the system process complex and the fault tolerance rate low; Second, the suction cup components are prone to wear and tear due to long-term contact with the stone edges and corners, resulting in insufficient reliability. Once a failure occurs, the stone slab breaking mechanism will also be unable to work, seriously affecting production efficiency.

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

This invention, through the rational coordination of a pallet device and a material dropping device, can stably receive broken stone slabs, avoiding the direct use of suction cups for adsorption and transfer, thus reducing the complexity of the equipment structure and operational risks.

[0006] This utility model provides a slab unloading and receiving mechanism for a stone unloading machine, including a pallet device, a material dropping device, and a breaking component. The pallet device is suspended in front of the stone processing position and can be raised, lowered, and reciprocated horizontally. The material dropping device is arranged below and behind the pallet device. The breaking component is arranged in the gap between two vertical stone slabs and can be raised, lowered, and reciprocated horizontally, causing the connection between the vertical stone slab at the processing position and its lower end to break. The pallet device stably receives and transfers the broken stone slab at the stone processing position to the surface of the material dropping device through raising, lowering, and horizontal movement.

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.

[0027] 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.

[0028] like Figures 1 to 4 As shown, the slab unloading and receiving mechanism of the stone unloading machine includes a pallet device 4, a material dropping device 2, and a breaking component 10. The pallet device 4 is suspended in front of the stone processing position and can be raised, lowered, and reciprocated horizontally. The material dropping device 2 is arranged below and behind the pallet device 4. The breaking component 10 is arranged in the gap between two vertical stone slabs 6 and can be raised, lowered, and reciprocated horizontally, so as to break the connection between the vertical stone slab 6 and its lower end in the processing position. The pallet device 4 stably receives and transfers the broken stone slab on the stone processing position to the surface of the material dropping device 2 through raising, lowering, and horizontal movement.

[0029] The material feeding device 2 includes a receiving plate or a plurality of receiving rollers 21 arranged in a row.

[0030] The material feeding device 2 is equipped with a movable cutting workpiece 3. The cutting workpiece 3 is used to process the connection between the lower end of the vertical stone slab 6 and the original stone base 7 in the processing position from the front into a weak connection that is easy to break. Specifically, several receiving rollers 21 are equipped with a conveying moving shaft 31 and a conveying moving guide rail 32 arranged in a row with them; the bottom of the cutting workpiece 3 is rotatably connected to the conveying moving shaft 31 and is provided with a conveying moving slider 33 that is slidably connected to the conveying moving guide rail 32; a cutting machine drive motor 34 is provided on the support frame 1. The cutting machine drive motor 34 is connected to the conveying moving shaft 31. The cutting machine drive motor 34 drives the conveying moving shaft 31 to rotate, thereby driving the cutting workpiece 3 and the conveying moving slider 33 to move on the conveying moving shaft 31 and the conveying moving guide rail 32. The conveying moving guide rail 32 and the conveying moving slider 33 are used to ensure that the cutting workpiece 3 can move stably.

[0031] Furthermore, the top height of the conveying moving shaft 31 is lower than the top height of several receiving rollers 21.

[0032] In another embodiment, the material feeding device 2 includes a receiving plate that is horizontally and reciprocally mounted on the support frame 1 and arranged in a row with the conveying moving shaft 31 and the conveying moving guide rail 32.

[0033] The plate unloading and receiving mechanism also includes a crossbeam 11, on which the pallet device 4 and the breaking component 10 are mounted; the crossbeam 11 is connected to a drive device, and the drive device drives the pallet device 4 and the breaking component 10 to move horizontally and reciprocally; the pallet device 4 is located on the front side of the breaking component 10.

[0034] The breaking component 41 can be configured as an insert plate or an insert rod. In this embodiment, the breaking component 41 is configured as an insert plate. The insert plate is located on the rear side of the movable plate 41. The insert plate is connected to the driving device through a crossbeam. The driving device drives the insert plate to apply a forward thrust to the vertical stone slab 6 located at the processing position, so that the connection part at the lower end of the vertical stone slab 6 breaks, thereby causing the vertical stone slab 6 to tilt towards the material dropping device 2.

[0035] The crossbeam 11 is mounted on the support frame 1 in a way that allows it to be raised, lowered, and moved horizontally back and forth via a drive device.

[0036] The driving device includes a horizontal moving module 5 and a lifting moving module 8. Both ends of the pallet device 4 are connected to the horizontal moving module 5, and are further connected to the lifting moving module 8 through the horizontal moving module 5.

[0037] The horizontal moving module 5 includes a first connecting plate 51, a first slide rail slider structure 52, a first driving mechanism 53, and a first transmission structure 54; the first connecting plate 51 is connected to the lifting moving module 8, and the first driving mechanism 53 is provided on it. The first driving mechanism 53 is connected to the pallet device 4 through the first transmission structure 54; the pallet device 4 is slidably connected to the first connecting plate 51 through the first slide rail slider structure 52.

[0038] Specifically, the first slide rail-slider structure 52 includes a first slide rail and a first slider. The first slide rail is horizontally mounted on the first connecting plate 51, and the first slider is mounted on the crossbeam. The first transmission structure 54 specifically includes a lead screw and a nut. The output end of the first drive mechanism 53 is connected to the lead screw, and the nut is threadedly connected to the lead screw. The nut is located at the end of the crossbeam 11. The first drive mechanism 53 is a motor.

[0039] The lifting and moving module 8 includes a second slide rail slider structure 81, a second drive mechanism 82, and a second transmission structure 83. The second drive mechanism 82 is disposed on the horizontal moving module 5, and the second transmission structure 83 is disposed on the support frame 1. The second drive mechanism 82 is connected to the second transmission structure 83. The horizontal moving module 5 and the support frame 1 are slidably connected through the second slide rail slider structure 81.

[0040] Specifically, the second slide rail and slider structure 81 includes a second slide rail and a second slider. The second slide rail is vertically mounted on the support frame 1, and the second slider is located on the back of the first connecting plate 51. The second transmission structure 83 is a rack and pinion, vertically mounted on the support frame 1, and the output end of the second drive mechanism 82 is meshed with the rack and pinion. When the second drive structure 82 operates, it drives the entire horizontal moving module 5 to perform lifting and lowering movements.

[0041] The pallet device 4 includes a movable plate 41, which is movably mounted on the crossbeam 11 and can move downwards from the crossbeam 11. The movable plate 41 is lowered when it is necessary to unload and receive the sheet material. The maximum downward movement of the movable plate 41 is such that its bottom is higher than the cutting workpiece 3 to prevent collision between the two.

[0042] A connection control mechanism is provided between the crossbeam 11 and the movable plate 41. The connection control mechanism includes an electric push rod 42 fixedly installed at the bottom of the crossbeam 11. The output end of the electric push rod 42 is connected to the bottom of the movable plate 41. A guide channel 45 is provided inside the crossbeam 11 to cooperate with the movable plate 41, so as to guide the movable plate 41 to move up and down stably. When the movable plate 41 is not working, it can be stored in the guide channel 45.

[0043] A fixed plate 43 is provided at the bottom of the crossbeam 11. The fixed plate 43 is located on the front side of the movable plate 41. A third slide rail 44 is provided on the movable plate 41, and a third slider is provided on the fixed plate 43. The movable plate 41 is slidably connected to the fixed plate 43 through the cooperation of the third slide rail 44 and the third slider.

[0044] 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.

[0045] After the upright stone slab 6 is pushed to the processing position by the trolley 9, the cutting workpiece 3 (such as a cutting machine) begins to cut the bottom of the upright stone slab 6 at the processing position, making the connection between the lower end of the upright stone slab 6 and the original stone base slab 7 a weak connection that is easy to break. Subsequently, the crossbeam 11, the breaking component 10, and the pallet device 4 move to the vicinity of the upright stone slab 6 under the drive of the horizontal moving module 5. Specifically, the insert plate moves to the upper rear of the upright stone slab 6 at the processing position, and the movable plate 41 and the fixed plate 43 move to the upper front of the upright stone slab 6. Then, the crossbeam 11, the breaking component 10, and the pallet device 4 move downward under the action of the lifting moving module 8 until the insert plate moves to the gap between the upright stone slab at the processing position and the upright stone slab behind it.

[0046] The horizontal moving module 5 drives the insert plate forward. As the insert plate abuts against the upper part of the vertical stone slab 6, the forward movement of the insert plate will exert a forward thrust on the vertical stone slab 6, causing the connecting part at the lower end of the vertical stone slab 6 to break.

[0047] After the stone slab breaks, it tilts forward and falls onto the movable plate 41. At this time, the horizontal moving module 5 drives the crossbeam 11 to continue moving forward, while the lifting moving module 8 drives the crossbeam 11 to move downward, thereby driving the movable plate 41 to guide the vertical stone slab 6 to tilt through forward and downward movements, so that it transitions to the surface of the dropping device 2 in a controlled posture.

[0048] The unloading device 2 then rolls or moves forward (receiving roller 21 or receiving plate) to remove the stone slab from its surface to the next processing station. While the stone slab is being removed, the cutting workpiece 3 begins to cut or tap the bottom of the next upright stone slab 6. The operation can start from the left or right side, forming a continuous operation process, thereby improving the overall unloading efficiency and automation level.
