Description

Technical Field

[0001] This utility model relates to the field of abrasive cloth processing technology, specifically a heat setting mechanism for multi-directional abrasive cloth base. Background Technology

[0002] Sandpaper is commonly used to remove burrs, rust, and oxides from metal surfaces. In woodworking, sandpaper can be used to smooth wood surfaces, making them smoother. The base material used for sandpaper is usually cloth, which needs to be heat-set during the manufacturing process to prevent the sandpaper from deforming or tearing during use after production, thus affecting its normal use.

[0003] A search revealed a drying and stretching device for abrasive cloth base with publication number CN222008387U. This device includes a frame, a stretching device, and a drying device mounted on the frame. The drying device includes a drying chamber mounted on the frame, designed to meet the health requirements of workshop workers and the temperature requirements for heat setting after stretching the abrasive cloth base. However, this device lacks a structure to stabilize the abrasive cloth base during drying and setting, making it prone to edge curling due to heat, thus affecting the setting effect. Therefore, we propose a multi-directional heat setting mechanism for abrasive cloth base. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides an improved heat-setting mechanism for a multi-directional abrasive cloth base. Please refer to [link / reference]. Figures 1-3 The system includes: a frame 1; a motor 2 is bolted to one outer wall of the frame 1; the output shaft of the motor 2 is connected to a roller 3, and the roller 3 passes through the inner side of the frame 1 via bearings; a conveyor belt 4 is fitted onto the outer wall of the roller 3; the conveyor belt 4 is rotatably connected to the frame 1 via the roller 3 and the output shaft of the motor 2; a heat-setting box 5 is bolted to the upper inner wall of the frame 1; a heating frame 6 is embedded in the lower outer wall of the heat-setting box 5; the lower outer wall of the heating frame 6 is parallel to the upper surface of the conveyor belt 4 via the heat-setting box 5; heating wires 7 are threaded through the upper inner wall of the heating frame 6 and are evenly distributed at equal intervals along the upper inner wall of the heating frame 6; the heating wires 7 serve as a heat source inside the heating frame 6, enabling the heating frame 6 to provide heat-setting function for the abrasive cloth base on the conveyor belt 4 at the lower end of the heat-setting box 5; a mesh 8 is laid on the lower outer wall of the heating frame 6; and openings are made on the lower surfaces of both sides of the heat-setting box 5. There is a pressure groove 9, and an electric telescopic rod 10 is bolted to the inner side of the pressure groove 9. The telescopic end of the electric telescopic rod 10 is fixed with a support rod 11. The support rod 11 is telescopically connected to the pressure groove 9 through the telescopic end of the electric telescopic rod 10. The lower surfaces of both ends of the support rod 11 are connected to spring columns 12. The other end of the spring column 12 is connected to a pressure roller 13 through a rotating shaft. The pressure roller 13 is elastically rotatably connected to the support rod 11 through the spring column 12. The rotation angle range of the pressure roller 13 is 0-5°. The pressure roller 13 is telescopically extended and retracted at the lower end of the heat setting box 5 through the telescopic end of the electric telescopic rod 10. When the pressure roller 13 extends downward and comes into contact with the abrasive cloth base, the elastic rotation function of the spring column 12 causes the pressure roller 13 to rotate and shift outward of the heat setting box 5, pressing and stretching both sides of the abrasive cloth base to prevent the abrasive cloth base from curling during the heat setting process and affecting the heat setting effect.

[0022] Please see Figure 2A multi-directional abrasive cloth-based heat setting mechanism includes: a heat dissipation cavity 14 is provided inside the upper end of the heat setting box 5, and an exhaust fan 15 is bolted to the outer wall of the upper end of the heat setting box 5, and the heat dissipation cavity 14 and the exhaust fan 15 are connected in communication. The heat dissipation cavity 14 and the exhaust fan 15 are provided to help dissipate the heat accumulated in the heat setting box 5 when the electric telescopic rod 10 and the heating wire 7 are working, to prevent this part of the heat from accumulating inside the heat setting box 5 and causing the heat setting box 5 to overheat, and to prevent personnel or equipment from being burned by contact with the heat setting box 5.

[0023] Please see Figure 1 and Figure 4 A multi-directional heat-setting mechanism for abrasive cloth base includes: side plates 16 made of fluororubber fixed to the outer walls of both sides of a conveyor belt 4, the side plates 16 being used to prevent the abrasive cloth base conveyed by the conveyor belt 4 from falling off the conveyor belt 4; a bracket 17 fixed to the inner surface of the side plate 16, the bracket 17 being evenly distributed at equal intervals along the inner surface of the side plate 16, the bracket 17 being used to engage and fix a heat insulation plate 18; a heat insulation plate 18 is placed inside the bracket 17, a lifting lug 19 is fixed to the upper outer wall of the heat insulation plate 18, and the heat insulation plate 18 and the bracket 17 form a detachable structure through the lifting lug 19, the heat insulation plate 18 being suspended inside the bracket 17 through the lifting lug 19, facilitating disassembly, replacement and maintenance, and the multiple heat insulation plates 18 being used to isolate the heat-set abrasive cloth base, preventing the heat-setting box 5 from affecting other abrasive cloth bases when heat-setting a single abrasive cloth base.

[0024] Working Principle: For this type of multi-directional abrasive cloth heat-setting mechanism, the operator first places the frame 1 of the mechanism on a stable, level working surface in the working environment. The motor 2 installed on the frame 1 drives the roller 3 and conveyor belt 4 to rotate stably inside the frame 1, transferring the abrasive cloth base to be set. Subsequently, the abrasive cloth base on the conveyor belt 4 is separated by the heat insulation plate 18 installed inside the side plate 16 and the card holder 17 to prevent interference with adjacent abrasive cloth bases during heat setting. When the abrasive cloth base to be set is transferred to the lower end of the heat-setting box 5, the conveyor belt 4 stops, and the electric telescopic mechanism in the pressure groove 9 at the lower end of the heat-setting box 5... The telescopic end of rod 10 extends downward, driving the support rod 11 and pressure roller 13 to move downward. Under the action of spring column 12, pressure roller 13 presses and stretches both ends of the abrasive cloth base. Pressure roller 13 can rotate 0-5° to the outside of heat setting box 5, which can better unfold both ends of the abrasive cloth base and prevent the edges of the abrasive cloth base from curling during heat setting. Finally, the electric heating wire 7 in the heating frame 6 works to generate heat to heat set the abrasive cloth base. The partition 8 can prevent the abrasive cloth base from directly contacting the electric heating wire 7. The heat accumulated in the heat setting box 5 when the electric telescopic rod 10 and electric heating wire 7 are working can be discharged through heat dissipation cavity 14 and exhaust fan 15.
