Description

Technical Field

[0001] The utility model relates to the technical field of sanding machines, in particular to a primer sanding machine for plate spray painting. Background Art

[0002] Primer sander is a practical equipment for plate painting, mainly used for grinding and polishing the surface of the plate to better carry out primer coating. It has a significant effect in improving production efficiency, yield rate and reducing labor intensity. However, the existing primer sander is not convenient for limiting the position of wood when grinding wood, which easily causes the wood to shift during the grinding process, affecting the grinding quality.

[0003] In order to address the above problems, the existing Chinese patent with announcement number CN214869488U proposes a primer sander for wooden products. The device drives the connecting block to rise through the second cylinder, so that the connecting rods at both ends of the connecting block drive the limit plates to move toward each other at both ends of the guide rod, so that the limit plates can fit the two sides of the plate to limit it, thereby avoiding the phenomenon of offset during the sanding process. The structure is simple and the sanding quality is improved.

[0004] However, although the above-mentioned primer sanding machine for wood products can drive the connecting block to rise through the second cylinder, so that the connecting rods at both ends of the connecting block drive the limit plates to move toward each other at both ends of the guide rod, so that the limit plates can fit the two sides of the plate to limit it, thereby avoiding the phenomenon of deviation during the sanding process, but when the primer sanding machine for wood products limits and sands the wood products, the grinding roller can only sand the wood products relative to the position thereof, thereby causing the problem of low sanding efficiency for the wood products. Therefore, the utility model provides a primer sanding machine for plate painting to meet the demand. Utility Model Content

[0038] Specifically, the lower grinding roller 13 and the driving roller 2 are in the same horizontal plane. The plate is placed on the driving roller 2 between the two clamping mechanisms 7, and then the clamping mechanism 7 is used to clamp the plate. At the same time, the rotating mechanism 9 drives the upper grinding roller 6 and the lower grinding roller 13 to rotate relative to each other, and the driving assembly 8 drives the clamping mechanism 7 and the plate to slide along the sanding machine body 1 to the grinding area 10 for grinding. The overall operation is simple, and the plate can be grinded in all directions, thereby improving the grinding efficiency of the plate. The problem of low plate grinding efficiency caused by the existing primer sanding machine when the plate is limited for grinding is solved.

[0039] like Figure 2 and Figure 4As shown, in this embodiment, the driving assembly 8 includes two threaded rods 82, which are arranged on both sides of the sanding machine body 1 for relative rotation, and the two threaded rods 82 are connected by a first belt transmission mechanism 84. A motor 81 is fixedly arranged on the sanding machine body 1 and the driving end of the motor 81 is connected to one of the threaded rods 82. The motor 81 is signal-connected to the control mechanism 4. A slider 83 is fixedly connected to the clamping mechanism 7. The slider 83 is sleeved and threadedly connected to the threaded rod 82. The slider 83 is slidably connected to the sanding machine body 1. The sanding machine body 1 is provided with a slide groove 5 for the slider 83 to slide. Specifically, the threaded rod 82 is driven to rotate by the cooperation of the motor 81 and the first belt transmission mechanism 84, so that the slider 83 slides along the slide groove 5, which is convenient for moving the plate.

[0040] like Figures 1 to 3 As shown, in the present embodiment, the rotating mechanism 9 comprises a third rotating shaft 94, which is rotatably arranged on the supporting plate 3, a gear 1 92 is sleeved on the third rotating shaft 94, the third rotating shaft 94 and the second rotating shaft 14 are connected via a second belt transmission mechanism 91, the third rotating shaft 94 is driven by a motor 2 95, the motor 2 95 is signal-connected to the control mechanism 4, the gear 2 93 is sleeved on the first rotating shaft 12 and meshes with the gear 2 93, specifically, the gear 1 92 is driven to rotate by the motor 2 95, the gear 1 92 drives the gear 2 93 to rotate, the gear 2 93 drives the first rotating shaft 12 to rotate, and at the same time, the third rotating shaft 94 drives the second rotating shaft 14 to rotate via the second belt transmission mechanism 91, so that the upper grinding roller 6 and the lower grinding roller 13 can rotate relative to each other, thereby improving the symmetry when grinding the plate.

[0041] like Figures 3 to 6 As shown, in this embodiment, the clamping mechanism 7 includes a fixed plate 75, which is fixedly connected to the slider 83, a fixed block 72 is relatively fixedly connected to the fixed plate 75, and a rotating plate 74 is rotatably connected to the fixed block 72; a clamping plate 71 is fixedly connected to the top of the rotating plate 74, an electric push rod 73 is fixed to the fixed plate 75, a driving end of the electric push rod 73 is fixedly connected to the bottom of the rotating plate 74, and the electric push rod 73 is suitable for pushing the rotating plate 74 to rotate along the fixed plate 75, the electric push rod 73 is connected to the control mechanism 4 by signal, and the rotating plate 74 is inclined with respect to the fixed plate 75. The clamping plate 71 is fixedly connected, and one end of the clamping plate 71 facing away from the rotating plate 74 is fixedly connected with a rubber pad 15, and a plurality of anti-slip grooves 16 are fixedly connected to the rubber pad 15. Specifically, the rotating plate 74 is driven to rotate by the electric push rod 73, so that the rotating plate 74 drives the clamping plate 71 to rotate and clamp the plate. The overall linkage is high, and the clamping efficiency of the plate is improved. At the same time, the rubber pad 15 can prevent the clamping plate 71 from causing damage to the plate, and the anti-slip grooves 16 increase the friction between the clamping plate 71 and the plate, further improving the stability of the plate clamping.

[0042] like Figure 1 As shown, in this embodiment, a position sensor 11 is fixedly connected to the end of the sanding machine body 1, and the position sensor 11 is connected to the control mechanism 4 by signal. Specifically, when the plate moves to the position corresponding to the position sensor 11, the position sensor 11 senses and sends a signal to the control mechanism 4, so that the control mechanism 4 releases the clamping mechanism 7 from clamping the plate, and drives the clamping mechanism 7 to reset through the driving assembly 8 to facilitate the next sanding of the plate.

[0043] Working principle:

[0044] By placing the plate on the transmission roller 2 between the two clamping mechanisms 7, and then driving the rotating plate 74 to rotate through the electric push rod 73, the rotating plate 74 drives the clamping plate 71 to rotate and clamp the plate, and at the same time, the motor 2 95 drives the gear 1 92 to rotate, the gear 1 92 drives the gear 2 93 to rotate, the gear 2 93 drives the first rotating shaft 12 to rotate, and at the same time the third rotating shaft 94 drives the second rotating shaft 14 to rotate through the second belt transmission mechanism 91, so that the upper grinding roller 6 and the lower grinding roller 13 can rotate relative to each other, and the threaded rod 82 is driven to rotate under the cooperation of the motor 1 81 and the first belt transmission mechanism 84, so that the slider 83 slides along the slide groove 5, so that the plate slides along the sanding machine body 1 to the grinding area 10 for grinding. The overall operation is simple, the plate can be grinded in all directions, and the grinding efficiency of the plate is improved. The problem that the grinding roller of the existing primer sander can only grind the plate relative to the plate when the plate is limited for grinding is solved, thereby causing low grinding efficiency of the plate.
