Description

Technical Field

[0001] The utility model belongs to the technical field of rock slab cutting equipment, and specifically belongs to a rock slab cutting machine. Background Technique

[0002] Rock slabs are made from natural raw materials through special processes, pressed by a press of over 10,000 tons (exceeding 15,000 tons), combined with advanced production technologies, and fired at a high temperature of over 1200 °C. They are super-large-sized new ceramic materials that can withstand processing such as cutting, drilling, and grinding. Rock slabs are mainly used in the fields of home and kitchen boards. As a new species in the home field, compared with other home products, rock slab furniture has the characteristics of large size, strong plasticity, diverse colors, high temperature resistance, wear and scratch resistance, anti-permeability, acid and alkali resistance, zero formaldehyde, environmental protection and health.

[0003] During the process of cutting rock slabs, it is often necessary to perform horizontal and vertical cuts on the rock slabs. When the traditional rock slab cutting machine needs to perform a horizontal cut after a vertical cut on the rock slab, it often needs to output and adjust the placement of the rock slab before performing the horizontal cut, or convey it to the next station for horizontal cutting, and it cannot achieve horizontal and vertical cuts on the rock slab at the same station at one time. Content of the Utility Model

[0004] In view of this, the purpose of the present utility model is to overcome the deficiencies in the prior art and provide a rock slab cutting machine. The present application provides the following technical solutions:

[0005] It includes a frame, a longitudinal guide rail frame is fixed on the frame, a transverse guide rail frame is slidably installed on the longitudinal guide rail frame, knife rest guide rails are arranged on both sides of the transverse guide rail frame, a plurality of lifting knife rests are installed on the knife rest guide rails, longitudinal cutting machines are installed on the lifting knife rests on one side of the transverse guide rail frame in a lifting and sliding manner, and transverse cutting machines are installed on the lifting knife rests on the other side of the transverse guide rail frame in a lifting and sliding manner.

[0006] With the above settings, after fixing the rock slab under the horizontal guide frame, when a vertical cutting machine is needed for cutting, the lifting tool rest lowers the vertical cutting machine, and the vertical cutting machine cuts the rock slab. Then, through the sliding of the horizontal guide frame on the vertical guide frame, the vertical cutting machine performs a straight-line cutting, and the position of the lifting tool rest with the vertical cutting machine after sliding displacement on the tool rest guide determines the cutting position of the vertical cutting machine; when a horizontal cutting machine is needed for cutting, the lifting tool rest lowers the horizontal cutting machine, and the horizontal cutting machine cuts the rock slab. Then, through the sliding of the lifting tool rest with the horizontal cutting machine on the tool rest guide, the horizontal cutting machine performs a straight-line cutting, and the position of the horizontal guide frame after sliding displacement on the vertical guide frame determines the cutting position of the horizontal cutting machine; it realizes horizontal and vertical cutting of the rock slab at the same station without moving the rock slab.

[0007] A vertical guide is bolted to the upper part of the vertical guide frame, and a vertical rack is bolted to the side part. At both ends of the bottom of the horizontal guide frame, there are fixed horizontal guide seats, and the horizontal guide seats are installed on the vertical guide. At the bottom of the horizontal guide seat, a vertical driving motor is fixedly installed, and a traveling gear meshing with the vertical rack is installed on the main shaft of the vertical driving motor; two horizontal racks are bolted to the top of the horizontal guide frame, and horizontal driving motors are fixedly installed at the tops of the lifting tool rests on both sides of the horizontal guide frame, and traveling gears meshing with the horizontal racks are installed on the main shafts of the horizontal driving motors. Among them, the traveling gears on the horizontal driving motors on the lifting tool rests on the same side mesh with the same horizontal rack.

A lifting motor is fixedly installed at the top of the lifting tool rest, and a lifting lead screw is connected to the main shaft of the lifting motor; the slider pair of the lifting lead screw is fixedly connected to the cutting machine mounting frame.

[0009] A conveyor belt and a rock slab centering mechanism are installed on the machine frame, and both the conveyor belt and the rock slab centering mechanism are located under the horizontal guide frame; the rock slab centering mechanism is used to push and center the rock slab on the conveyor belt.

[0010] By setting the rock slab centering mechanism, the position of the rock slab is moved and positioned, making the cutting more accurate.

[0011] A chassis is arranged under the upper belt of the conveyor belt, and the chassis is fixed to the machine frame, and the chassis supports and holds up the upper belt of the conveyor belt; the rock slab centering mechanism is located on both sides of the chassis.

[0012] By setting the chassis to support the upper belt of the conveyor belt, the upper belt of the rock slab is supported, so that the rock slab is stably placed, preventing the vertical stress of the cutting machine on the rock slab from pressing the upper belt downward and affecting the cutting effect when the rock slab is cut.

[0013] The rock slab centering mechanism includes two centering guide rail frames located on both sides of the chassis. The centering guide rail frames are fixed on the machine frame. A centering guide rail and a push plate are arranged on the centering guide rail frames. Both ends of the push plate are installed on the centering guide rail. A driving lead screw and a lead screw motor are also arranged on the centering guide rail frames. The middle part of the push plate is installed on the driving lead screw. The main shaft of the lead screw motor is in transmission connection with the driving lead screw. The push plate moves horizontally in a straight line along the centering guide rail towards the conveyor belt under the drive of the driving lead screw.

[0014] A dust scraping mechanism is further arranged at the bottom of the transverse guide rail frame. The dust scraping mechanism includes a connecting seat. The connecting seat is bolted and fixed to the bottom of one side of the transverse guide rail frame. An installation surface is obliquely arranged on the connecting seat. A scraper guide rail and a scraper cylinder are bolted and fixed on the installation surface. A scraper is installed on the scraper guide rail. The scraper is connected to the telescopic rod of the scraper cylinder.

[0015] By setting the dust scraping mechanism, after the rock slab is cut and output by the conveyor belt, the surface of the rock slab is scraped to remove the dust or mortar that falls on the surface of the rock slab after cutting.

The rock slab can be conveyed through the conveyor belt. The rock slab centering mechanism pushes and centers the rock slab on the conveyor belt. After the rock slab is cut, the surface of the rock slab can also be cleaned by the dust scraping mechanism.

[0036] Among them, the conveyor belt 2 includes rotating rollers and a belt sleeved on the rotating rollers. Among the rotating rollers, there is a driving roller, and the driving roller is driven to rotate by a motor. The driving roller drives the belt to rotate through friction, and other driven rotating rollers follow. The belt above the rotating rollers is the upper belt, and the belt below the rotating rollers is the lower belt.

[0037] Below the upper belt of the conveyor belt 2, a chassis 21 is provided. The chassis 21 is fixed to the frame 1, and the chassis 21 holds and supports the upper belt of the conveyor belt 2; the slab centering mechanism 3 is located on both sides of the chassis 21.

[0038] The slab centering mechanism 3 includes two centering guide rail frames 31 located on both sides of the chassis 21. The centering guide rail frames 31 are fixed to the frame 1. A centering guide rail 32 and a push plate 33 are provided on the centering guide rail frames 31. Both ends of the push plate 33 are installed on the centering guide rail 32. A driving lead screw 34 and a lead screw motor 35 are also provided on the centering guide rail frames 31. The middle part of the push plate 33 is fixedly installed on the slider pair of the driving lead screw 34. The main shaft of the lead screw motor 35 is in transmission connection with the lead screw of the driving lead screw 34 through a gear structure. The push plate 33 moves horizontally in a straight line along the centering guide rail 32 towards the conveyor belt 2 under the drive of the driving lead screw 34.

[0039] A dust scraping mechanism 4 is further provided at the bottom of the transverse guide rail frame 12. The dust scraping mechanism 4 includes a connecting seat 41. The connecting seat 41 is bolted and fixed to the bottom of one side of the transverse guide rail frame 12. An installation surface is inclinedly arranged on the connecting seat 41. A scraper guide rail 42 and a scraper cylinder 43 are bolted and fixed on the installation surface. A scraper 44 is installed on the scraper guide rail 42. The scraper 44 is connected to the telescopic rod of the scraper cylinder 43.

[0040] Among them, the longitudinal guide rail 111, the tool rest guide rail 121, the lifting guide rail 134, and the scraper guide rail 42 are all linear guide rails in the prior art, and being installed on the guide rail means being installed on the sliding pair on the guide rail.

[0041] It should be noted that for the convenience of realizing electric control, an electric control cabinet can also be provided. The power switches of the longitudinal driving motor 123, the longitudinal cutting machine 131, the transverse cutting machine 132, the transverse driving motor 133, the lifting motor 136, the conveyor belt 2, the lead screw motor 35, and the scraper cylinder 43 are all integrated in the electric control cabinet through wires. The start and stop of each workpiece are realized by opening and closing the power switch. To further realize precise electric control, a PLC control cabinet or a main control computer can also be provided. The longitudinal driving motor 123, the longitudinal cutting machine 131, the transverse cutting machine 132, the transverse driving motor 133, the lifting motor 136, the conveyor belt 2, the lead screw motor 35, and the scraper cylinder 43 are electrically connected to the PLC control cabinet or the main control computer through wires to realize precise control.

[0042] During specific implementation, the staff places the slab on the conveyor belt 2, then starts the conveyor belt 2 and stops it when the slab is transported directly above the chassis 21. Then the lead screw motor 35 is started. The gear on the main shaft of the lead screw motor 35 meshes with the gear on the lead screw of the driving lead screw 34. The lead screw motor 35 drives the lead screw 34 to rotate, so that the push plate 33 slides along the centering guide rail 32 under the push of the driving lead screw 34 and approaches the conveyor belt 2. The push plates 33 on both sides of the conveyor belt 2 approach the conveyor belt 2 simultaneously, pushing and centering the slab on the conveyor belt 2 to complete the fixation of the slab.

[0043] Then, position the cutting tool: Start the longitudinal drive motor 123. The rotation of the main shaft of the longitudinal drive motor 123 drives the traveling gear on its main shaft to rotate. The traveling gear meshes with the longitudinal rack 113, and the longitudinal rack 113 is fixed to the machine frame 1. Therefore, when the traveling gear rotates, it drives the longitudinal drive motor 123 and the transverse guide rail seat 122 to slide along the longitudinal guide rail 111. At this time, the transverse guide rail frame 12 slides on the longitudinal guide rail frame 11. Start the transverse drive motor 133. The rotation of the main shaft of the transverse drive motor 133 drives the traveling gear on its main shaft to rotate. The traveling gear meshes with the transverse rack 124, and the transverse rack 124 is fixed to the transverse guide rail frame 12. Therefore, when the traveling gear rotates, it drives the lifting tool rest 13 and the cutting machine on the lifting tool rest 13 to slide along the tool rest guide rail 121. The movement of the transverse guide rail frame and the lifting tool rest drives the cutting machine to move horizontally and longitudinally above the rock slab, so that it moves above the cutting entry point where the rock slab needs to be cut.

[0044] Then, start the cutting machine and lower the tool: Start the longitudinal cutting machine 131 or the transverse cutting machine 132; Start the lifting motor 136. The rotation of the main shaft of the lifting motor 136 drives the screw rod of the lifting lead screw 137 to rotate. The lifting lead screw 137 pushes the cutting machine mounting frame 135 and the longitudinal cutting machine 131 or the transverse cutting machine 132 on the cutting machine mounting frame 135 to move downward until the cutting tool on the cutting machine contacts the rock slab for cutting.

[0045] Longitudinal cutting: After positioning and lowering the tool for the longitudinal cutting machine 131, start the longitudinal drive motor 123 to longitudinally slide the transverse guide rail frame 12 on the longitudinal guide rail frame 11, driving the longitudinal cutting machine 131 to move longitudinally on the rock slab for cutting.

[0046] Transverse cutting: After positioning and lowering the tool for the transverse cutting machine 132, start the transverse drive motor 133 to horizontally slide the lifting tool rest 13 and the cutting machine on the lifting tool rest 13 along the tool rest guide rail 121, driving the transverse cutting machine 132 to move horizontally on the rock slab for cutting.

[0047] After each cutting by lowering the tool is completed, start the lifting motor 136 and reverse it. The rotation of the main shaft of the lifting motor 136 drives the screw rod of the lifting lead screw 137 to rotate. The lifting lead screw 137 pushes the cutting machine mounting frame 135 and the longitudinal cutting machine 131 or the transverse cutting machine 132 on the cutting machine mounting frame 135 to move upward for retracting the tool.

[0048] After the rock slab cutting is completed, start the scraper cylinder 43. The elongation of the scraper cylinder 43 drives the scraper 44 to move downward along the scraper guide rail 42, making the bottom of the scraper 44 contact the surface of the rock slab. Then start the conveyor belt 2. The conveyor belt 2 drives the rock slab to move. The scraper moves relative to the rock slab on the surface of the rock slab to scrape off the mortar or dust on the surface of the rock slab; and convey the cut rock slab out.

[0049] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present application. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present application.
