DETAILED DESCRIPTION
[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with illustrations and specific embodiments.
[0024] Embodiment 1: Figures 1 to 6 As shown, the utility model proposes a sanding belt conveying mechanism in a polishing device, including a frame 1, wherein the frame 1 is provided with a belt supply assembly for loading the sanding belt, a belt collection assembly for storing the used sanding belt, and a conveying assembly for conveying the sanding belt. After the sanding belt comes out of the belt supply assembly, it passes through the conveying assembly and the working area in sequence and is recovered by the belt collection assembly.
[0025] The tape supply assembly includes a tape supply shaft 2 rotatably connected to the frame 1, a tape supply reel 3 fixedly mounted on the tape supply shaft 2, and a control structure arranged between the frame 1 and the tape supply shaft 2 to control the rotation of the tape supply shaft 2, wherein the control structure is used to limit the rotation of the tape supply shaft 2 so that the abrasive belt maintains a certain tension, that is, to prevent the abrasive belt from being in a loose state due to the situation that the tape supply shaft 2 rotates too fast. During use, the rolled abrasive belt is sleeved on the tape supply reel 3, and the abrasive belt is driven by the traction force to overcome the limitation of the control structure and drive the tape supply shaft 2 and the tape supply reel 3 to rotate and then move toward the conveying assembly.
[0026] In this embodiment, the control structure includes a control seat 4 disposed on the frame 1 and through which the supply shaft 2 passes, an opening 5 provided on the side wall of the control seat 4, and a bolt 6 disposed on the control seat 4 and capable of causing the gap of the opening 5 to become smaller and clamping the supply shaft 2, wherein the bolt 6 is perpendicular to the cross section of the opening 5. The control structure is to tighten the bolt 6 to make the opening 5 smaller, thereby limiting the aperture of the control seat 4 from becoming smaller so as to form a certain clamping force between the control seat 4 and the supply shaft 2, and finally limiting the rotation of the supply shaft 2. In addition, a rubber sleeve 7 is installed between the control seat 4 and the supply shaft 2, and the friction between the supply shaft 2 and the control seat 4 is increased by the rubber sleeve 7.
[0027] The conveying assembly includes a guide seat 8 installed on the frame 1, and the guide seat 8 is provided with a belt feed pulley 9 and a belt take-up pulley 10, and the belt feed pulley 9 and the belt take-up pulley 10 are respectively located on the upper and lower sides of the guide seat 8, and the guide seat 8 is provided with two groups of elastic structures for installing the belt feed pulley 9 and the belt take-up pulley 10 respectively. The elastic structure includes a slide plate 11 slidably connected to the guide seat 8 in a vertical direction, and an elastic member 12 driving the slide plate 11 to move toward the guide seat 8 is provided between the guide seat 8 and the slide plate 11. In this embodiment, the elastic member 12 is a spring, and the belt feed pulley 9 and the belt take-up pulley 10 are rotatably installed on the slide plate 11 respectively, and the rotation circumference of the belt feed pulley 9 and the belt take-up pulley 10 is horizontally arranged and perpendicular to the length direction of the guide seat 8. There is a gap for the sanding belt to pass through between the side wall of the belt feed pulley 9 and the side wall of the belt take-up pulley 10 and the surface of the guide seat 8, that is, in this embodiment, the belt feed pulley 9 and the belt take-up pulley 10 are driven by the spring to move toward each other and make the sanding belt in a tensioned state. The slide plate 11 is also fixedly connected with a conveying driver 13 for driving the corresponding feed wheel 9 or take-up wheel 10 to rotate. The conveying driver 13 can be a servo motor, that is, it can realize the forward or reverse rotation of the feed wheel 9 or take-up wheel 10. When in use, the abrasive belt extended from the supply reel 3 enters through the gap between the feed wheel 9 and the guide seat 8 and enters the polishing operation area. At this time, the sand surface of the abrasive belt contacts the feed wheel 9, and the feed wheel 9 is driven by the spring to move toward the guide seat 8 so that the abrasive belt is in a tensioned state, and the feed wheel 9 is driven by the conveying driver 13 to rotate to achieve the traction of the abrasive belt. Similarly, after the use, the abrasive belt enters between the take-up wheel 10 and the guide seat 8, and the take-up wheel 10 is driven by the spring to move toward the guide seat 8, thereby achieving the effect of tensioning the abrasive belt, and the take-up wheel 10 is driven to rotate by the corresponding driving conveyor to achieve the traction of the abrasive belt. That is, the above-mentioned conveying assembly can realize the traction of the abrasive belt and achieve the renewal of a section of the abrasive belt in the polishing operation area.
[0028] In this embodiment, a rubber layer is provided on the side walls of the feed pulley 9 and the take-up pulley 10. The elasticity of the rubber layer prevents the sanding belt from being over-tensioned and increases the friction force to ensure the movement of the sanding belt.
[0029] Since the roughness of the sand surface of the sand belt after use is reduced, the friction force becomes smaller after the belt take-up wheel 10 contacts the sand surface of the sand belt. To ensure that the belt take-up wheel 10 can drive the sand belt to move normally, the slide plate 11 connected to the belt take-up wheel 10 is rotatably connected to the driven wheel 14, which is arranged parallel to the belt take-up wheel 10, and the side wall of the driven wheel 14 is elastic. When in use, the sand belt after use passes through the driven wheel 14 and the belt take-up wheel 10 in turn and then enters the belt take-up assembly. The driven wheel 14 can effectively increase the contact area between the sand belt and the belt take-up wheel 10, thereby increasing the friction force, and ensuring that the belt take-up wheel 10 drives the sand belt to move synchronously.
[0030] The take-up assembly is located directly below the tape supply assembly, and the take-up assembly includes a take-up shaft 15 rotatably connected to the frame 1, a take-up reel 16 fixedly connected to the take-up shaft 15, and a take-up motor 17 arranged on the frame 1 and driving the take-up shaft 15 to rotate. The take-up motor 17 can be a servo motor or the like that can realize the forward or reverse rotation of the take-up shaft 15. A transmission structure that ensures the normal rotation of the take-up motor 17 when the take-up shaft 15 stops is arranged between the take-up shaft 15 and the frame 1. The transmission structure can be a damper, that is, when the sanding belt received by the take-up reel 16 is in a tensioned state, after the take-up motor 17 rotates, the damper can be used to prevent the take-up shaft 15 from being unable to rotate and causing a malfunction, that is, the damper can be used to ensure that the take-up motor 17 can idle normally when the take-up reel is stopped due to a large resistance.
[0031] When this embodiment is in use, the sanding belt extends from the supply reel 3 through the gap between the feed pulley 9 and the guide seat 8 and bypasses the feed pulley 9 to enter the polishing operation area. Then, the sanding belt passes through the gap between the take-up reel 10 and the guide seat 8 and bypasses the driven wheel 14 and the take-up reel 10 to enter the take-up reel 16 for recovery. The elastic structure can keep the sanding belt in a tensioned state, and the two conveying drivers 13 are used to drive the sanding belt to move and update a section of the sanding belt in the polishing operation area, so as to achieve continuous polishing.
[0032] Embodiment 2 is different from Embodiment 1 in that: Figure 7 and Figure 8 As shown, the control structure includes an elastic pressure rod 18 fixed to the frame 1 at one end, and a rolling member 19 rotatably connected to the other end of the elastic pressure rod 18 and capable of contacting the supply shaft 2 or the side wall of the supply reel 3 (selectively located on the side wall of the supply reel 3 in this embodiment) to control the rotation of the supply reel 3. The rolling member 19 can be a ball, etc., and the rolling member 19 is made of a flexible material. The rotation of the supply reel 3 can be limited by the rolling member 19 contacting the side wall of the supply reel 3, thereby preventing the supply reel 3 from rotating too fast and causing the sanding belt to be in a loose state.
