Description

Technical Field

[0001] This utility model relates to the technical field of artificial stone textured slab production equipment, specifically to an artificial stone slab texture generation device. Background Technology

[0002] Existing artificial stone slab texture generation devices, in order to embed the texture material into the fluid slurry on the upper layer of the artificial stone texture slab, directly insert the texture material outlet pipe of the texture material injector into the fluid slurry on the upper layer of the artificial stone texture slab. This structure is prone to clogging of the texture material outlet pipe, and the resulting textures are monotonous and the work efficiency is not high.

[0003] To address the aforementioned issues, the applicant filed an application on September 22, 2023, and published patent document CN221338908U on July 16, 2024. This patent includes a base with a scraper at its front end. The scraper is used to scrape the fluid slurry on the upper layer of the artificial stone textured board to form a material groove. A textured material injector is located on the base, near the rear side of the scraper, to inject the textured material into the material groove of the base material. Multiple downward-extending claws are located at the rear of the base, arranged side-by-side with gaps between adjacent claws. The textured material injector includes a limiting and fixing ring, a textured material container, and a textured material outlet pipe. The textured material outlet pipe communicates with a discharge hole at the bottom of the textured material container. The textured material container is mounted on the limiting and fixing ring, which is mounted on a frame. The textured material container is a cylindrical structure with an open top. A plug is provided at the discharge hole, and a long rod-shaped handle is attached to the plug. One end of the long rod-shaped handle is located outside the textured material container, and the other end extends into the textured material container and is fixedly connected to the plug. A hook is provided on the long rod-shaped handle for hanging it on the side wall of the upper port of the textured material container. In use, first plug the discharge hole of the texture material container with the conical plug, inject the texture material into the texture material container, then insert the texture material container through the auxiliary limiting ring into the limiting fixing ring, and then place this artificial stone slab texture generating device on the upper layer of the artificial stone texture slab. Pull the plug out of the discharge hole through the long rod-shaped handle, and hang the long rod-shaped handle with the plug on the side wall of the upper port of the texture material container. When the texture material flows down along the texture material outlet pipe, start moving the machine base. The scraper scrapes the upper layer of the artificial stone texture slab and forms a material groove. The texture material injector injects the texture material into the material groove of the base material.

[0004] Although the aforementioned patent documents have solved the relevant problems of the prior art, their technical solutions still have the following shortcomings in practical applications and need to be improved: First, the discharge control requires manual removal of the blockage from the discharge hole using a long rod-shaped handle, which is not simple to operate and has a low degree of mechanization; Second, the discharge volume cannot be precisely controlled. In actual operation, during the feeding process, sometimes the material blockage occurs, resulting in insufficient discharge volume, while sometimes the discharge volume is too large, causing the material to accumulate in the slurry tank. Utility Model Content

[0005] The purpose of this invention is to provide a device for generating patterns in artificial stone slabs that is highly mechanized, can precisely control materials, and ensure uniform material feeding.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A pattern generating device for artificial stone slabs includes a pattern material hopper. Multiple discharge hoppers are arranged side-by-side at the bottom of the hopper. The lower end of each discharge hopper is connected to a pattern material outlet pipe. The lower end of the outlet pipe has a tubular connector. One side of the connector is connected to the upper end of a grooving knife, and the other side is connected to one end of a connecting longitudinal beam. The other end of the longitudinal beam is connected to a crossbeam, on which multiple scrapers are distributed. A discharge spiral is installed in the outlet pipe. The upper end of the spiral is connected to the lower end of a drive shaft. The upper end of the drive shaft is connected to a variable frequency motor at the top of the hopper. The variable frequency motor drives the discharge spiral to rotate via the drive shaft. The discharge rate of the pattern material from the outlet pipe is adjusted by regulating the speed of the variable frequency motor.

[0008] Furthermore, the lower end face of the grooving tool protrudes downward to form a pointed tip.

[0009] Furthermore, a feed hopper is provided on one side of the top of the textured material hopper.

[0010] Furthermore, a material distribution screw is provided inside the texture material hopper and located on the drive shaft. When material is fed from the feed hopper into the texture material hopper, the frequency converter drives the drive shaft to rotate in the opposite direction, thereby driving the material distribution screw to rotate, so that the texture material is evenly distributed in the texture material hopper.

[0011] Furthermore, the artificial stone slab texture generating device also includes a gantry frame, on which two guide rods are provided, and guide sliders are provided on the two guide rods. The texture material bin is installed on the guide sliders on the two guide rods.

[0012] Furthermore, the artificial stone slab texture generating device also includes an electric push rod, the end of which is hinged to the side of the texture material bin, and the electric push rod is used to push the texture material bin to move along the guide rod.

[0013] Furthermore, the artificial stone slab texture generating device also includes a conveyor belt, on which an artificial stone slab material layer is laid, and the gantry frame spans across the conveyor belt.

[0014] Furthermore, the left and right vertical supports of the gantry frame are provided with sliding grooves, and lifting blocks and lifting electric push rods are provided in the sliding grooves. The lifting blocks are supported on the lifting electric push rods, and the lifting electric push rods are installed at the bottom of the sliding grooves. The two ends of the two guide rods are fixed to the lifting blocks on the left and right vertical supports. The lifting electric push rods push the lifting blocks to move up and down along the sliding grooves to adjust the grooving depth of the grooving knife on the artificial stone slab material layer.

[0015] The beneficial effects of this utility model are as follows:

[0016] This application improves upon existing technology. In actual production in the workshop, it reduces the intervention of workers in both material discharge control and slotting movement, and achieves precise control of material discharge, precise control of slotting depth, control of the shape of tortuous patterns, and control of uniform material distribution. This application features simple operation, high degree of mechanization, and high degree of automation. Attached Figure Description

[0026] like Figure 1 , 2 As shown in Figure 3, an artificial stone slab texture generation device includes a texture material hopper 1. Multiple discharge hoppers 2 are arranged side-by-side at the bottom of the texture material hopper 1. A texture material outlet pipe 3 is connected to the lower end of each discharge hopper 2. A tubular connector 4 is provided at the lower end of the texture material outlet pipe 3. A discharge spiral 5 is provided in the texture material outlet pipe 3. The upper end of the discharge spiral 5 is connected to the lower end of a drive shaft 6. The upper end of the drive shaft 6 is connected to a variable frequency motor 7 at the top of the texture material hopper 1. The variable frequency motor 7 drives the discharge spiral 5 to rotate via the drive shaft 6. The amount of texture material discharged from the texture material outlet pipe 3 is adjusted by regulating the rotational speed of the variable frequency motor 7.

[0027] A feed hopper 8 is provided on one side of the top of the textured material bin 1. A material spreading screw 9 is provided inside the textured material bin 1 and on the drive shaft 6. When material is fed into the textured material bin 1 from the feed hopper 8, the frequency converter motor 7 drives the drive shaft 6 to rotate in the opposite direction, so as to drive the material spreading screw 9 to rotate, so that the textured material is evenly distributed in the textured material bin 1.

[0028] The artificial stone slab texture generation device also includes a gantry frame 10, on which two guide rods 11 are provided, and guide sliders 12 are provided on the two guide rods 11. The texture material bin 1 is mounted on the guide sliders 12 on the two guide rods 11. It also includes an electric push rod 13, the end of which is hinged to the side of one side of the texture material bin 1. The electric push rod 13 is used to push the texture material bin 1 to move along the guide rods 11.

[0029] The artificial stone slab texture generation device also includes a conveyor belt 14, on which an artificial stone slab material layer 15 is laid, and the gantry frame 10 spans across the conveyor belt 14.

[0030] The gantry frame 10 includes vertical support bodies 16 on the left and right sides. A sliding groove 17 is provided on the vertical support bodies 16 on the left and right sides. A lifting block 18 and a lifting electric push rod 19 are provided in the sliding groove 17. The lifting block 18 is supported on the lifting electric push rod 19. The lifting electric push rod 19 is installed at the bottom of the sliding groove 17. The two ends of the two guide rods 11 are fixed to the lifting block 18 on the vertical support bodies on the left and right sides. The lifting electric push rod 19 pushes the lifting block 18 to move up and down along the sliding groove 17 to adjust the grooving depth of the grooving knife 20 on the artificial stone slab material layer.

[0031] like Figure 4 , 5 As shown, one side of the tubular connector 4 is connected to the upper end of the grooving knife 20, and the other side of the tubular connector 4 is connected to one end of the connecting longitudinal beam 21. The other end of the connecting longitudinal beam 21 is connected to a crossbeam 22. Multiple scrapers 23 are distributed on the crossbeam 22. The lower end face of the grooving knife 20 protrudes downward to form a pointed tip.

[0032] Working principle: When the conveyor belt 14 transports the artificial stone slab material layer 15 to below the grooving knife 20 at the gantry frame 10, the lifting electric push rod 19 is activated, pushing the lifting block 18 up and down along the slide 17 to adjust the grooving depth of the grooving knife 20 on the artificial stone slab material layer 15. As the conveyor belt 14 continues to drive the artificial stone slab material layer 15, multiple grooving knives 20 open multiple grooves on the surface of the artificial stone slab material layer 15. At the same time, the variable frequency motor 7 is activated. The variable frequency motor 7 drives the discharge screw 5 to rotate through the transmission shaft 6. The textured material in the textured material bin 1 falls into the corresponding grooves through the discharge hopper 2 and the textured material outlet pipe. Multiple scrapers 23 scrape the corresponding grooves flat and scrape up the mixture of textured material on the upper layer of the artificial stone slab material layer 15. The mixture flows out from the gap between adjacent scrapers 23, thus forming a gradient multi-layered fused textured line.

[0033] The feature of this application is that the outflow of texture material can be precisely adjusted and controlled. The outflow of texture material from the texture material outlet pipe can be adjusted by adjusting the speed of the variable frequency motor.

[0034] The electric push rod 13 is used to push the texture material bin 1 to move along the guide rod 11, and to control the specific position of the grooving knife 20 and the texture material outlet pipe. In conjunction with the moving conveyor belt 14, it forms a tortuous texture on the surface of the artificial stone material layer 15.

[0035] In this application, the feed hopper 8 is located on one side of the texture material bin 1. Since the texture material bin 1 is a long and narrow cavity structure, when the texture material is fed from the feed hopper 8 into the texture material bin 1, the texture material tends to accumulate near the feed hopper 8, which will cause uneven material distribution. Therefore, a material distribution screw 9 is added to the drive shaft 6. The frequency converter motor 7 drives the drive shaft 6 to rotate in the opposite direction, so as to drive the material distribution screw 9 to rotate. The material distribution screw 9 can throw the texture material near the texture material feed hopper to one side, avoid the accumulation of texture material, and make the texture material evenly distributed in the texture material bin 1.

[0036] This application is also equipped with a PLC controller. By inputting the relevant motor speed, number of motor rotations and motor direction into the PLC controller, precise control of material discharge, precise control of slotting depth, control of the shape of the tortuous texture and control of uniform material distribution can be achieved.

[0037] Furthermore, those skilled in the art can combine and integrate the different embodiments or examples described herein, as well as the features of those different embodiments or examples, without contradiction. Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
