Description

Technical Field

[0001] The invention relates to the technical field of surfboards, in particular to anti-corrosion polyurea spraying equipment and a spraying method for a water sports board. Background Art

[0002] Surfboards are sports equipment used by people for surfing. The surfboards used initially were about 5 meters long and weighed 50 to 60 kilograms. The surfboards used now are 1.5 to 2.7 meters long, about 60 centimeters wide, and 7 to 10 centimeters thick. The board is light and flat, slightly narrow at the front and back ends, and has a tail fin at the rear bottom for stabilization. In order to increase friction, a waxy outer film is also applied to the board surface.

[0003] Polyurea is an elastomeric substance generated by the reaction of isocyanate components and amino compound components. Spraying anti-corrosion polyurea on the outer surface of a surfboard can make the surfboard effectively resistant to seawater. However, during the spraying process, a clamping device is generally required to clamp the surfboard, so that the clamped part cannot be sprayed. Because the polyurea coating on the surfboard is not dry yet, it is not convenient to move the surfboard to replace the clamping part and clamp it again. Therefore, we propose an anti-corrosion polyurea spraying device for water sports boards and a spraying method thereof. Summary of the invention

[0019] S1: During use, the rotating handle is first pulled outward to pull out the plug inserted in the first slot, and the plug is inserted into the second slot, and then rotated. Since the plug fits the inner wall of the second slot, the rotating handle drives the second movable shaft to rotate when it is rotated, and then drives the spline shaft to rotate;

[0051] The steps include:

[0052] S1: During use, the rotating handle 303 is first pulled outward to pull out the insert block 302 inserted in the first slot, and the insert block 302 is inserted into the second slot, and then rotated. Since the insert block 302 fits with the inner wall of the second slot, the rotating handle 303 drives the second movable shaft 404 to rotate when rotating, and then drives the spline shaft 406 to rotate;

[0053] S2: When the spline shaft 406 rotates, since the spline shaft 406 is sleeved with two spline sleeves 405, the two spline sleeves 405 rotate simultaneously, thereby driving the collar 503 sleeved on the outer surface of the spline sleeve 405 to rotate, so that the second bevel gear 502 rotates simultaneously, and since the first bevel gear 501 and the second bevel gear 502 are meshed and connected, the first bevel gear 501 and the second bidirectional threaded rod 5 on the inner wall thereof rotate simultaneously;

[0055] S4: At this time, the four clamping rollers 204 are spread out in pairs, and the surfboard is stood up horizontally and placed between the four clamping rollers 204 and fits with the two moving plates 203. At this time, the rotating handle 303 is rotated in the opposite direction, and the above-mentioned actions are repeated to make the four clamping rollers 204 close to each other, until the four clamping rollers 204 are closely fitted with the front and back of the surfboard, and the position of the surfboard is fixed;

The output end of the drive motor drives the rotating shaft 104 to rotate, and then drives the surfboard fixing bar 2 to rotate around the rotating shaft 104 as the axis, so that the surfboard can be sprayed 360°;

[0057] S6: After the spraying is roughly finished, the driving motor is turned off, so that the surfboard fixing strip 2 and the surfboard stop rotating. At this time, the insert block 302 is inserted into the first slot, and then the rotating handle 303 is rotated to drive the first movable shaft 301 to rotate, thereby driving the first bidirectional threaded rod 3 to rotate. The two thread grooves with opposite rotation directions on the outer surface of the first bidirectional threaded rod 3 drive the two moving blocks 202 to slide in the opposite direction on the inner wall of the moving groove 201. At the same time, the two positioning blocks 403 drive the two moving blocks 402 to slide in the opposite direction in the movable groove 4, so that the two spline sleeves 405 slide on the outer surface of the spline shaft 406;

[0058] S7: At the same time, the two moving blocks 202 slide in the opposite direction to make the two moving plates 203 move in the opposite direction, thereby making the four clamping rods 508 move in the opposite direction between each other, and at the same time making the four clamping rollers 204 roll on the front and back of the surfboard, so as to expose the unsprayed parts blocked by the four clamping rollers 204, and spray them at this time, so that the surfboard can be sprayed 360° without touching the surfboard, and the clamped parts can still be sprayed, and there will be no residual unsprayed parts.

[0059] By setting the clamping roller 204, and the clamping roller 204 is in contact with the surfboard, when the clamping rod 508 moves, the clamping roller 204 can rotate relative to the surfboard, so that the clamping position can be freely changed, which is convenient for spraying with the surfboard. By setting the rotating handle 303, it is convenient to rotate the first movable axis 301 and the second movable axis 404. By setting the plug block 302, the first slot and the second slot, when rotation is required, the plug block 302 is inserted into the first slot or the second slot for rotation. When the spray head is in operation, the plug block 302 and the rotating handle 303 are pulled out to prevent the rotating handle 303 from being stained with paint and then touched by the hand.

Since the insert block (302) fits against the inner wall of the second slot, the rotating handle (303) drives the second movable shaft (404) to rotate when it is rotated, and then drives the spline shaft (406) to rotate; S2: When the spline shaft (406) rotates, since the spline shaft (406) is sleeved with two spline sleeves (405), the two spline sleeves (405) rotate simultaneously, thereby driving the collar (503) sleeved on the outer surface of the spline sleeve (405) to rotate, so that the second bevel gear (502) rotates simultaneously, and since the first bevel gear (501) and the second bevel gear (502) are meshed and connected, the first bevel gear (501) and the second bidirectional threaded rod (5) on the inner wall thereof rotate simultaneously; S3: When the second bidirectional threaded rod (5) rotates, the two thread grooves with opposite rotation directions provided on its outer surface drive the two transmission blocks (504) to slide in opposite directions on the inner wall of the cavity, and drive the two fixing plates (507) to slide in opposite directions through the two connecting blocks (505), so that the two clamping rods (508) move in opposite directions, thereby increasing the distance between the two clamping rollers (204); S4: At this time, the four clamping rollers (204) are spread out in pairs, the surfboard is stood up horizontally and placed between the four clamping rollers (204), and fits with the two movable plates (203). At this time, the rotating handle (303) is rotated in the opposite direction, and the above-mentioned actions are repeated, so that the four clamping rollers (204) are close to each other, until the four clamping rollers (204) are tightly fitted with the front and back of the surfboard, and the position of the surfboard is fixed; S5: At this time, the handle (303) is pulled outward again to disengage the plug (302) from the second slot, and then the surfboard is sprayed with a spray gun containing anti-corrosion polyurea. At the same time, the drive motor is turned on, and the output end of the drive motor drives the rotating shaft (104) to rotate, thereby driving the surfboard fixing bar (2) to rotate around the rotating shaft (104), so that the surfboard can be sprayed 360 degrees; S6: After the spraying is roughly completed, the driving motor is turned off, so that the surfboard fixing strip (2) and the surfboard stop rotating. At this time, the insert block (302) is inserted into the first slot, and then the rotating handle (303) is rotated to drive the first movable shaft (301) to rotate, thereby driving the first bidirectional threaded rod (3) to rotate. The two thread grooves with opposite rotation directions provided on the outer surface of the first bidirectional threaded rod (3) drive the two movable blocks (202) to slide in opposite directions on the inner wall of the movable groove (201), and at the same time, the two positioning blocks (403) drive the two movable blocks (402) to slide in opposite directions in the movable groove (4), so that the two spline sleeves (405) slide on the outer surface of the spline shaft (406); S7: At the same time, the two moving blocks (202) slide in the opposite direction to make the two moving plates (203) move in the opposite direction, thereby making the four clamping rods (508) move in the opposite direction between each other, and at the same time making the four clamping rollers (204) roll on the front and back of the surfboard, so that the unsprayed part blocked by the four clamping rollers (204) is exposed, and then sprayed, so that the surfboard can be sprayed 360 degrees without contacting the surfboard, and the clamped part can still be sprayed, and there will be no remaining unsprayed part.
