Description

TECHNICAL FIELD

[0001] The present application relates to a stone processing device, in particular to a stone feeding system. BACKGROUND

[0002] The processing of stone, including sawing, cutting, grinding, drilling, and sculpting of rock. In terms of plate processing, it is mainly sawing. According to the different stone processing technology, it can be divided into special-shaped products (including carving, arc plate, hollow column, solid column, line, and mosaic) and plate products (including large plate, specification plate, and thin plate).

[0003] During the processing of stone, the edge of the stone needs to be ground (the outer edge and the inner edge). In the prior art, an automatic horizontal edge grinding machine is generally used to grind the inner edge of the horizontally placed stone plate. At the same time, it can also be used to make upper and lower chamfers. During the grinding process, the main structure of the grinding machine is a conveying device connected to the machine frame. The conveying device is provided with an edge grinding device on one side. During processing, the edge grinding device grinds the stone while the conveying device presses and forwards the stone, which can prevent the stone from deviating. However, since the length of the stone is generally long, a long conveying device is required. At the same time, since different thicknesses of stone need to be processed during the processing process, the conveying device needs to be adjusted again to adapt to different thicknesses of the plate when the thickness of the stone changes. However, since the existing conveying device and the machine frame are connected and fixed at multiple places, multiple adjustments are required, which not only increases the workload, but also easily causes changes in installation accuracy and inaccuracy, thereby affecting the processing accuracy of the stone.

[0035] In use, first start the vertical lifting mechanism 400, unlock the fixing mechanism 600, then according to the thickness of the stone, the vertical lifting mechanism 400 drives the compression roller device 300 to ascend and descend, so that the distance between the first roller 320 and the conveying belt 200 is equal to the thickness of the stone, when the position is adjusted, the vertical lifting mechanism 400 stops, at this time the fixing mechanism 600 will tightly fix the connecting mechanism 500, so that the up and down position of the whole compression roller device 300 is fixed. Then the stone can be conveyed into the conveying belt 200, with the continuous conveying of the conveying belt 200, the stone enters between the conveying belt 200 and the compression roller device 300, and the compression roller is pressed on the stone. At the same time, the edge grinding device of the automatic horizontal edge grinding machine performs edge grinding work.

[0036] The stone feeding system can conveniently adjust the height of the pressing roller device 300 according to the thickness of the stone, so that the installation precision of the whole pressing roller device 300 is not changed, and the processing quality of the stone is further ensured.

[0037] In the embodiment, the vertical lifting mechanism 400 comprises a lifting rod 410 and a vertical lifting power source 420 arranged on the mounting arm 800, the lifting rod 410 is arranged on a power output shaft of the vertical lifting power source 420 and connected with the horizontal plate 310, and the vertical lifting power source 420 can drive the lifting rod 410 to vertically lift.

[0038] In the embodiment, the vertical lifting power source 420 is selected from the lifting motors commonly used in the prior art. Of course, in other embodiments, the vertical lifting mechanism 400 can also be selected as a hoist or other lifting mechanism.

The cantilever 510 is connected with the rack, the cantilever 510 is provided with a through slot penetrating upward and downward and located directly above the conveying belt 200, one end of the connecting rod 520 is connected with the horizontal plate 310, the other end of the connecting rod 520 is slidably and vertically upward through the through slot, the fixing mechanism 600 is arranged on the cantilever 510, the fixing mechanism 600 is arranged on the cantilever 510 and tightly locked on the connecting rod 520, and the vertical lifting mechanism 400 is connected with the fixing mechanism 600. The vertical lifting mechanism 400 can drive the fixing mechanism 600 to be unlocked when the connecting rod 520 is in the lifting process.

[0040] The fixing mechanism 600 comprises a clamping driving source 610 and a clamping clamp 620. The clamping clamp 620 has two, the two clamping clamps 620 are arranged on the cantilever 510 and located on the left and right sides of the connecting rod 520, the clamping driving source 610 is connected between the lifting rod 410 and the clamping clamp 620, and when the lifting rod 410 is lifted or lowered, the clamping clamp 620 can be driven by the clamping driving source 610 to move in opposite directions.

[0041] When the connecting rod 520 is in a static state, the clamping clamp 620 is clamped on the connecting rod 520 at this time, when the vertical lifting mechanism 400 drives the lifting rod 410 to lift or lower, the lifting rod 410 drives the clamping clamp 620 to move in opposite directions through the clamping driving source 610, so that the connecting rod 520 is unlocked, and the connecting rod 520 can be lifted or lowered, and when the lifting is completed, the clamping clamp 620 clamps the connecting rod 520 again, so as to assist in fixing the position of the whole pressing roller device 300.

[0042] Specifically, the holding driving source 610 comprises a piston cylinder 611, an elastic support 612, a generator 613, a mounting block 614, a transmission rack 615, a gear 616, an electromagnet 617 and an electric wire 618. The piston cylinder 611 is fixed on the cantilever 510, and a through hole is formed on the side of the piston cylinder 611 facing the connecting rod 520. The holding clamp 620 is slidably inserted into the piston cylinder 611 through the through hole, and is connected with the piston cylinder 611 through the elastic support 612. Under the action of the elastic support 612, the holding clamp 620 is held on the connecting rod 520. The holding clamp 620 has magnetism. The transmission rack 615 is arranged on the outer wall of the lifting rod 410. The mounting block 614 is mounted on the rack of the automatic horizontal edge grinding machine and is located above the conveying belt 200. A through hole is formed on the mounting block 614 corresponding to the position of the lifting rod 410. The lifting rod 410 is slidably inserted into the through hole. The generator 613 is mounted on the mounting block 614. The gear 616 is rotatably arranged on the mounting block 614 and is engaged with the rack. The central shaft of the gear 616 is connected with the generator 613. When the rotating shaft of the gear 616 rotates, the generator 613 can generate electricity.

[0043] The electromagnet 617 is arranged in the piston cylinder 611 and is located at the end away from the connecting rod 520. The electric wire 618 is electrically connected with the generator 613, and is wound on the electromagnet 617 inserted into the piston cylinder 611. When the electric wire 618 has current passing through, the electromagnet 617 generates the same magnetic field as the holding clamp 620.

[0044] When the vertical lifting power source 420 drives the lifting rod 410 to ascend or descend, the rack is driven to ascend or descend, and the gear 616 is driven to rotate, thereby driving the generator 613 to generate electricity, so that the electromagnet 617 generates a magnetic field. Since the electromagnet 617 has the same magnetism as the holding clamp 620, the electromagnet 617 and the holding clamp 620 are attracted to each other, thereby driving the holding clamp 620 to retreat until the holding clamp 620 is separated from the connecting rod 520, and the connecting rod 520 can ascend or descend.

[0045] In this way, the height adjustment and installation of the automatic roller pressing device 300 can be realized through the operation, thereby greatly improving the work efficiency and the installation precision, and improving the processing quality of the product.

[0046] As a preferred embodiment, the system further comprises an auxiliary roller set 700, which is arranged in parallel with the conveying belt 200 and is arranged at the same height as the conveying belt 200. When the stone is relatively wide, the auxiliary roller set 700 can provide auxiliary support and conveying, thereby improving the application range of the edge grinding machine.

[0047] Specifically, the auxiliary roller set 700 includes a support beam 710, a supporting rod 720 and second rollers 730. The support beam 710 is arranged on the frame, the supporting rod 720 is arranged on the support beam 710 and arranged in the same direction as the conveying belt 200, and the second rollers 730 are arranged on the supporting rod 720 in a uniform interval and can roll, and are arranged at the same height as the conveying belt 200. When the stone is located between the conveying belt 200 and the pressing roller device 300, it is also located on the second roller 730, and the second roller 730 assists in supporting the stone.

[0048] In the embodiment, the supporting rod 720 includes a rod body and pressing rods. The transverse surface of the rod body is U-shaped, a plurality of mounting grooves in communication with the inner cavity of the rod body are arranged on the top surface of the left and right side walls of the rod body in a uniform interval along the length direction, the second rollers 730 are located in the inner cavity of the rod body, the shafts of the two ends of the second rollers 730 are arranged in the mounting grooves in a rolling manner, and the two pressing rods are detachably and tightly fixed on the top of the two ends of the rod body.

[0049] During installation, the pressing rods are first removed, the shafts of all the second rollers 730 are sequentially arranged in the mounting grooves, and then the pressing rods are installed on the rod body, so that the installation of all the second rollers 730 can be quickly completed.

[0050] In addition, the top surface of the support beam 710 is provided with a sliding groove perpendicular to the conveying direction of the conveying belt 200, and the rod body is slidably arranged in the sliding groove. During installation, the distance between the auxiliary roller set 700 and the conveying belt 200 can be adjusted according to the width of the stone, so as to further assist in supporting.

[0051] The use mode of the above stone feeding system is as follows:

[0052] During use, the position of the auxiliary roller set 700 is adjusted according to the width of the stone, then the vertical lifting mechanism 400 is started, the fixing mechanism 600 is unlocked, then the vertical lifting mechanism 400 drives the lifting rod 410 to rise or fall when the lifting rod 410 drives the rack to rise or fall, the gear 616 is driven to rotate, the generator 613 is driven to generate electricity, the electromagnet 617 generates a magnetic field, the electromagnet 617 and the clamping clamp 620 are magnetically attracted to each other, the clamping clamp 620 is driven to retreat until it is separated from the connecting rod 520, and the connecting rod 520 can be lifted up and down, so as to drive the pressing roller device 300 to rise or fall.

[0053] When the position is adjusted, the vertical lifting power source 420 stops lifting up and down, the gear 616 stops rotating, the current in the electric wire 618 disappears, the electromagnet 617 does not generate a magnetic field, and the clamping clamp 620 is clamped on the connecting rod 520 again under the action of the elastic support 612, so that the up and down position of the whole compression roller device 300 is fixed. Then the stone can be conveyed into the conveying belt 200, and as the conveying belt 200 continuously conveys, the stone enters between the conveying belt 200 and the compression roller device 300, the compression roller is pressed on the stone, and at the same time, the edge grinding device of the automatic horizontal edge grinding machine performs edge grinding work.

[0054] By using the above stone feeding system, the height of the compression roller device 300 can be adjusted conveniently according to the thickness of the stone, the installation precision of the whole compression roller device 300 is not changed, and the processing quality of the stone is further ensured.
