Description

Technical Field

[0001] This utility model relates to the field of building material processing equipment technology, and in particular to a fine grinding device for realizing continuous conveying of artificial stone. Background Technology

[0002] Grinding is a core step in the processing of artificial stone. It involves using sandpaper or abrasive tools (such as diamond wheels or resin grinding discs) to eliminate surface defects (such as saw marks and unevenness), making the substrate smooth and providing an ideal base for subsequent polishing.

[0003] Traditional polishing processes suffer from the following problems: The need for multi-stage polishing of stone, and the requirement for polishing each individual stone, necessitates repeated clamping and transfer using multiple devices, making the process cumbersome. Therefore, this paper proposes a device integrating conveying, multi-stage polishing, and automatic clamping functions. Through mechanical structural innovation, this device achieves efficient and precise processing of artificial stone. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that require repeated clamping and multiple equipment transfers, and to propose a fine grinding device for continuous conveying of artificial stone.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fine polishing device for continuous conveying of artificial stone includes a conveyor for continuously conveying artificial stone slabs;

[0007] The grinding mechanism includes a bracket, a sliding seat, a lifting seat, and a grinding disc. The bracket is located above the conveyor, the sliding seat is horizontally slidably connected to the bracket, the lifting seat is vertically slidably connected to the sliding seat, and the grinding disc is rotatably mounted at the bottom of the lifting seat via a rotating shaft.

[0008] The clamping mechanism includes two symmetrically arranged clamping plates, a sliding plate, and a linkage component. The sliding plate is horizontally slidably connected to both sides of the bracket. The top of the sliding plate is provided with an inclined surface. The lifting seat is fixed with abutment plates on both sides. When the lifting seat moves down, the abutment plates press against the inclined surface to drive the sliding plate to move inward. The linkage component drives the clamping plate to clamp the plate.

[0009] When the conveyor continuously conveys the sheet material, the lifting seat moves down to make the grinding disc contact the surface of the sheet material and automatically clamp the sheet material in conjunction with the clamping mechanism.

[0010] In one possible design, the polishing mechanism further includes:

[0011] Two No. 1 threaded rods are rotatably mounted inside the bracket and at the bottom of the sliding seat, respectively. The sliding seat and the lifting seat are threadedly engaged with the two No. 1 threaded rods.

[0012] Motor 1 and Motor 2 drive the two No. 1 threaded rods to rotate, thereby controlling the horizontal movement of the sliding seat and the vertical movement of the lifting seat;

[0013] Motor No. 3 is fixed to the top of the lifting base and drives the rotating shaft to rotate, thereby driving the grinding disc to rotate.

[0014] In one possible design, the clamping mechanism further includes:

[0015] The mounting strip is fixed to the bottom of the sliding plate via a connecting bracket.

[0016] The No. 2 threaded rod and the No. 2 limiting rod are respectively rotated and fixed to the side wall of the clamping plate. The mounting strip is threadedly engaged with the No. 2 threaded rod and slidably engaged with the No. 2 limiting rod.

[0017] In one possible design, a compression spring is provided between the sliding plate and the inner wall of the bracket, with both ends of the compression spring abutting through spring seats, which is used to drive the sliding plate to reset when the lifting seat rises.

[0018] In one possible design, the sidewall of the sliding plate is fitted with multiple balls that contact the abutment to reduce friction.

[0019] In one possible design, the grinding mechanism and clamping mechanism are arranged in multiple sets along the conveyor conveying direction, with the mesh size of the grinding discs in each set increasing sequentially to complete rough grinding, medium grinding and fine grinding respectively.

[0020] In one possible design, the spacing between adjacent grinding mechanisms is less than the length of the sheet material, so that the sheet material undergoes multiple grinding stages sequentially during continuous conveying.

[0021] In this application, during actual use, the stone is conveyed by a conveyor. When it is conveyed into the mechanism, the second motor is driven first, which drives the corresponding first threaded rod to rotate, thereby driving the lifting seat to move downward, so that the grinding disc below comes into contact with the surface of the stone. When the lifting seat begins to move downward, the abutment plate on its side wall will abut against the inclined surface at the top of the sliding plate, thereby pushing the sliding plate to move inward. The sliding plate will drive the clamping plate to move inward through the connecting frame and the mounting strip, thereby clamping the stone. Then, the third motor can be driven, which drives the grinding disc to rotate through the rotating shaft to achieve grinding. Furthermore, the first motor can be driven to drive the sliding seat to move horizontally back and forth, thereby performing reciprocating grinding.

[0022] In this utility model, the fine grinding device for continuous conveying of artificial stone can achieve grinding of the board during the conveying process by linking the conveyor and the grinding mechanism, thereby avoiding the need for separate loading and unloading each time and repeated manual clamping steps, thus improving efficiency.

[0023] In this utility model, the fine polishing device for continuous conveying of artificial stone can effectively reduce the friction between the boards by using ball bearings, thereby avoiding frictional wear during repeated polishing.

[0024] In this invention, the integrated design of continuous conveying and multi-stage grinding improves production efficiency. The entire process of rough grinding, medium grinding, and fine grinding can be completed during the conveying process, avoiding downtime caused by repeated clamping in traditional processes. Secondly, the adjustable clamping can achieve automatic opening and closing of the clamping plate through a mechanical linkage structure, which can adapt to different sizes of plates without additional power source, simplifying the operation process and reducing the complexity of the equipment.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Example 1

[0032] Reference Figure 1-2 A grinding device includes: a conveyor 1 and a grinding mechanism and a clamping mechanism.

[0033] The grinding mechanism consists of a support 2, a sliding seat 6, a lifting seat 7, and a grinding disc 9.

[0034] The bracket 2 is a frame structure, which is sleeved on the outside of the conveyor 1, and a limit rod 3 is fixed on its inner wall;

[0035] The sliding seat 6 is slidably sleeved on the outer wall of the first limiting rod 3 through a linear bearing, and the inner wall of the bracket 2 is rotatably provided with the first threaded rod 4. The sliding seat 6 forms a threaded transmission connection with the first threaded rod 4 through a threaded hole. The first motor 5 is fixed on the side wall of the bracket 2, and its output shaft is connected to the end of the first threaded rod 4 through a coupling.

[0036] Another set of No. 1 limit rods 3 are fixed at the bottom of the sliding seat 6. The lifting seat 7 is slidably sleeved on the outer wall of the set of No. 1 limit rods 3 through a linear bearing. Another No. 1 threaded rod 4 is rotatably set at the bottom of the sliding seat 6. The lifting seat 7 forms a threaded transmission connection with the No. 1 threaded rod 4 through a threaded hole. The No. 2 motor 20 is fixed at the top of the sliding seat 6, and its output shaft is connected to the end of the No. 1 threaded rod 4.

[0037] The bottom of the lifting seat 7 is equipped with a rotating shaft 8 via a bearing. The grinding disc 9 is fixed to the bottom of the rotating shaft 8 with screws. The No. 3 motor 21 is fixed to the top of the lifting seat 7, and its output shaft is connected to the top of the rotating shaft 8.

[0038] Reference Figure 3-4 The clamping mechanism consists of a clamping plate 12, a sliding plate 16, a connecting frame 10, and a mounting strip 13.

[0039] Both sliding plates 16 are slidably disposed inside the bracket 2 via a slider and a sliding groove structure. The top of the sliding plate 16 is machined with an inclined surface 15. The lifting seat 7 is welded with abutment plates 14 on both sides. When the lifting seat 7 moves down, the abutment plates 14 contact the inclined surface 15 and push the sliding plate 16 to slide inward, thereby realizing the clamping action.

[0040] A compression spring is provided between the side wall of the sliding plate 16 and the inner wall of the bracket 2. The two ends of the compression spring abut against the side wall of the sliding plate 16 and the inner wall of the bracket 2 respectively through spring seats, so as to be used for reset after clamping.

[0041] A connecting frame 10 is fixed to the bottom of the sliding plate 16 by bolts. An installation strip 13 is welded to the end of the connecting frame 10. The side wall of the installation strip 13 has threaded holes and smooth holes. The second threaded rod 11 is rotatably mounted on the side wall of the clamping plate 12 through a bearing. The second limiting rod 19 is welded to the side wall of the clamping plate 12. The installation strip 13 forms a threaded transmission connection with the second threaded rod 11 through the threaded hole and a sliding fit with the second limiting rod 19 through the smooth hole. By rotating the second threaded rod 11, the position of the clamping plate 12 can be adjusted, thereby achieving the clamping effect of stones of different sizes.

[0042] Specifically, the stone is conveyed by conveyor 1. When it is conveyed into the mechanism, motor 20 is driven first. Motor 20 will drive the corresponding threaded rod 4 to rotate, thereby driving the lifting seat 7 to move downward, so that the grinding disc 9 below is in contact with the surface of the stone. When the lifting seat 7 starts to move downward, the abutment plate 14 on its side wall will abut against the inclined surface 15 on the top of the sliding plate 16, thereby pushing the sliding plate 16 to move inward. The sliding plate 16 will drive the clamping plate 12 to move inward through the connecting frame 10 and the mounting strip 13, thereby clamping the stone. Then, motor 21 can be driven to drive the grinding disc 9 to rotate through the rotating shaft 8 to achieve grinding. Furthermore, motor 5 can be driven to drive the sliding seat 6 to move horizontally back and forth, thereby performing reciprocating grinding.

[0043] Work process:

[0044] The artificial stone slabs are conveyed to the polishing station via conveyor 1;

[0045] As the lifting seat 7 moves downward, the abutment plate 14 pushes the sliding plate 16 to move inward, and the clamping plate 12 moves inward synchronously with the mounting strip 13.

[0046] The sliding seat 6 moves along the X-axis, and the lifting seat 7 moves along the Z-axis, so that the grinding disc 9 contacts the surface of the board.

[0047] Motor 21 drives the grinding disc 9 to rotate for grinding, while conveyor 1 continuously conveys the board material to achieve continuous operation.

[0048] This application can be used in the field of building material processing equipment, or in other fields applicable to this application.

[0049] Example 2

[0050] refer to Figure 4 An improvement based on Embodiment 1: a fine grinding device for continuous conveying of artificial stone, which is applied to the field of building material processing equipment, wherein multiple balls 17 are embedded in the side wall of the sliding plate 16 to reduce the friction between the abutment plate 14 and the sliding plate 16.

[0051] A handwheel 18 is provided at the end of the No. 2 threaded rod 11.

[0052] An industrial vacuum cleaner can be installed on the side of each processing unit, and a protective shell can be installed on the outside of the motor to prevent dust pollution. The outer wall of the threaded rod can be protected by a corrugated tube.

[0053] The grinding and clamping mechanisms are equipped with multiple sets, with the grit of the grinding discs in each set increasing sequentially from 400# to 800# and 1500#. After the board is coarsely ground by the first set of grinding mechanisms, it directly enters the second set for medium grinding, and finally the third set completes the fine grinding, achieving multi-stage continuous grinding.

[0054] However, as is well known to those skilled in the art, the working principles and wiring methods of the motor and conveyor 1 are commonplace and are all conventional methods or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.
