Description

Technical Field

[0001] The present invention relates to the technical field of sports equipment production, and particularly to an anti-slip surface spraying device for sports equipment. Background Art

[0002] With the booming development of the sports industry, sports equipment is increasingly widely used in various sports venues, schools, gyms and other places. Among them, the horizontal bar, as a common fitness and training equipment, has a very high usage frequency. However, since the horizontal bar needs to bear the weight of the human body and various frictions during use, its surface is easily worn, and at the same time, it will adhere to floating dust and impurities due to environmental factors (such as dust, sweat, etc.). This not only affects the aesthetics of the horizontal bar, but more importantly, reduces its use safety. For example, an overly smooth surface may cause the user to slip and get injured.

[0003] In order to improve the service life and safety of the horizontal bar, it is particularly important to perform anti-slip treatment on its surface. Currently, the common anti-slip treatment method is to spray anti-slip paint on the surface of the horizontal bar. However, there are many problems with the existing anti-slip surface spraying devices. On the one hand, before spraying, it is often difficult to automatically clean the floating dust and impurities on the surface of the horizontal bar, resulting in insufficient adhesion between the anti-slip paint and the surface of the horizontal bar, and it is easy to fall off, thus affecting the anti-slip effect. On the other hand, during the spraying process of traditional spraying devices, it is difficult to achieve uniform spraying on the surface of the horizontal bar, and it is easy to have situations of missed spraying or over-thick spraying, resulting in uneven anti-slip performance on the surface of the horizontal bar and affecting the use effect. Therefore, we propose an anti-slip surface spraying device for sports equipment to solve the above-mentioned problems. Summary of the Invention

[0004] The purpose of the present invention is to solve the disadvantages in the prior art that when spraying the horizontal bar, it is impossible to clean the horizontal bar and uniformly spray the anti-slip paint, and to propose an anti-slip surface spraying device for sports equipment.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An anti-slip surface spraying device for sports equipment, including a spraying box, in which a painting mechanism is installed. A support frame is welded on one side of the spraying box, and a moving frame is slidably arranged on the support frame. A driving mechanism is connected through the moving frame, and a horizontal bar tube that needs to be sprayed with anti-slip paint is clamped on the driving mechanism. The spraying device further includes:

[0007] A grinding mechanism installed on the support frame, the horizontal bar tube penetrates through the grinding mechanism, and the grinding mechanism is used to grind the outer surface of the horizontal bar tube to clean the floating dust and impurities adhering to the outer surface of the horizontal bar tube;

[0008] The moving mechanism connected to the grinding mechanism is connected to the driving mechanism, and can drive the horizontal movement of the horizontal bar tube with the power source of the driving mechanism, so as to achieve the comprehensive grinding and spraying of anti-slip coating on the horizontal bar tube.

[0009] In a possible design, the painting mechanism includes a bracket welded inside the spraying box. An installation frame is welded on the bracket. A delivery pump is fixedly installed at the top of the installation frame through bolts. The discharge end of the delivery pump extends into the installation frame and is welded with a spraying plate. A delivery pipe is welded to the suction end of the delivery pump. One end of the delivery pipe is bonded with a hose, and the bottom end of the hose extends into the spraying box.

[0010] In a possible design, a plurality of positioning frames are welded at equal intervals on the top of the bracket. The same reflector is welded on the plurality of positioning frames. A plurality of baking lamp tubes are fixedly installed at equal intervals at the bottom of the reflector through bolts.

[0011] In a possible design, the driving mechanism includes a driving motor fixedly installed on one side of the moving frame through bolts. The output shaft of the driving motor penetrates through the moving frame and is welded with a clamping cover. One end of the horizontal bar tube extends into the clamping cover and fits against the inner wall of the clamping cover. A plurality of positioning screws are threadedly connected through the curved inner wall of the clamping cover at equal intervals. The positioning screws are used for clamping and positioning the horizontal bar tube. A connecting plate is rotatably connected to one side of the opening of the clamping cover. A jack communicating with the clamping cover is opened on the connecting plate. The horizontal bar tube penetrates through the jack. The connecting plate is connected to the moving mechanism, and the bottom of the moving mechanism is sleeved on the clamping cover.

[0012] In a possible design, a limiting frame is welded on both sides of the support frame. A sliding plate is slidably connected inside the limiting frame. The two sliding plates are respectively fixedly connected to both sides of the moving frame.

[0013] In a possible design, the moving mechanism includes a fixing screw connected to the grinding mechanism. A fixing frame is welded to one end of the fixing screw. The fixing frame is respectively welded to the two limiting frames. A nut is rotatably connected to the top of one side of the connecting plate. The fixing screw respectively penetrates through the connecting plate and the nut and is threadedly connected to the nut. A driving gear is fixedly sleeved on the clamping cover by welding. A driven gear is fixedly sleeved on the nut by welding. The driving gear meshes with the driven gear.

[0014] In a possible design, the grinding mechanism includes an equipment rack welded to one side of the top of the support frame. A first grinding bent rod is welded inside the equipment rack. Two slide rails are symmetrically welded inside the equipment rack. The same second grinding bent rod is slidably connected to the two slide rails. Grinding sandpapers are adhered to the inner sides of the arc bends of the first grinding bent rod and the second grinding bent rod through Velcro. The single-bar tube passes through the inner sides of the arc bends of the first grinding bent rod and the second grinding bent rod and can be in close contact with the two grinding sandpapers. Two threaded assemblies are symmetrically arranged at the top of the second grinding bent rod. Both threaded assemblies penetrate the inner wall of the top of the equipment rack and extend above the equipment rack. The threaded assemblies are connected to the top of the equipment rack.

[0015] In a possible design, the threaded assembly includes a threaded ring welded to the top of the equipment rack. A transmission screw rod is threadedly connected through the threaded ring. The bottom end of the transmission screw rod extends into the equipment rack and is rotatably connected to the second grinding bent rod through a bearing.

[0016] In this application, first pour the anti-slip coating to be used into the spraying box. Then insert one end of the single-bar tube into the clamping cover in the driving mechanism so that it fits against the inner wall of the clamping cover. Twist the positioning screw rod on the inner wall of the curved surface of the clamping cover to clamp and position the single-bar tube to ensure that the single-bar tube does not shake in the clamping cover. Pass the single-bar tube through the inner sides of the arc bends of the first grinding bent rod and the second grinding bent rod in the grinding mechanism. Then operate the two transmission screw rods. Under the threaded transmission cooperation with the corresponding threaded rings, the second grinding bent rod can be driven to move downward. With the support cooperation of the first grinding bent rod, the single-bar tube is clamped to ensure that the grinding sandpaper is in close contact with the surface of the single-bar tube. Start the driving motor to drive the clamping cover to rotate, thereby driving the single-bar tube to rotate. While the single-bar tube is rotating, the grinding sandpaper grinds and cleans the outer surface of the single-bar tube, cleaning the floating dust and impurities adhering to the outer surface of the single-bar tube. For horizontal movement and comprehensive grinding, when the clamping cover rotates, the driving gear on it meshes with the driven gear in the moving mechanism to drive the nut to rotate. Under the threaded transmission action of the nut and the fixed screw rod, the nut moves horizontally along the axis of the fixed screw rod, thereby driving the connecting plate and the single-bar tube to move horizontally. Through the rotation and horizontal movement of the single-bar tube, comprehensive grinding and cleaning of the single-bar tube are realized. Move the single-bar tube after grinding and cleaning under the painting mechanism in the spraying box. Start the transfer pump to draw out the anti-slip coating in the spraying box from the hose. After being pressurized and transported by the transfer pump, the anti-slip coating is transported to the spray plate. The spray plate is used to disperse and spray the anti-slip coating on the single-bar tube to achieve uniform spraying of the anti-slip coating on the single-bar tube. The moving single-bar tube will move under the reflector. Then turn on the power of the multiple baking lamp tubes at the bottom of the reflector. When the baking lamp tubes emit light, they generate heat to dry the anti-slip coating. After the anti-slip coating quickly sets on the single-bar tube, the entire spraying process can be completed.

[0017] Beneficial effects: In the present invention, for the anti-slip surface spraying device of a sports equipment, through the painting mechanism, when the cleaned and polished horizontal bar tube passes through the mounting rack, the anti-slip coating in the spraying tank can be pumped out through the hose by starting the delivery pump. After that, through the pressurized delivery of the delivery pump, the anti-slip coating can be transported to the spray plate, so that the anti-slip coating can be dispersed and sprayed on the horizontal bar tube by using the spray plate, so as to achieve uniform spraying of the anti-slip coating on the horizontal bar tube.

[0018] In the present invention, for the anti-slip surface spraying device of a sports equipment, through the driving mechanism, after one end of the horizontal bar tube that needs to be sprayed with the anti-slip coating is inserted into the clamping cover, at this time, the horizontal bar tube can be positioned and braked by twisting the positioning screw. Then, by starting the driving motor to drive the clamping cover to rotate, the horizontal bar tube can be driven to rotate. The rotating horizontal bar tube can form a frictional relationship with the cleaning mechanism, so as to facilitate the cleaning of the horizontal bar tube. And when the clamping cover rotates, it can drive the moving mechanism to move, that is, drive the horizontal bar tube to move horizontally, so as to comprehensively polish and clean the horizontal bar tube and spray the anti-slip coating.

[0019] In the present invention, for the anti-slip surface spraying device of a sports equipment, through the grinding mechanism, after the horizontal bar tube passes through between the first grinding bent rod and the second grinding bent rod, two threaded components can be operated to drive the second grinding bent rod to move downward. At this time, with the support and cooperation of the first grinding bent rod, the horizontal bar tube can be clamped, so that the grinding sandpapers on both sides are in close contact with the horizontal bar tube. Then, when the horizontal bar tube rotates and moves, the grinding sandpapers can be used to grind and clean the horizontal bar tube, so as to clean the floating dust and impurities adhering to the outer surface of the horizontal bar tube.

[0020] In the present invention, for the anti-slip surface spraying device of a sports equipment, through the moving mechanism, when the clamping cover rotates, it can drive the driving gear to rotate. At this time, under the meshing transmission with the driven gear, it can drive the nut to rotate. When the nut rotates, under the threaded transmission with the fixed screw, the nut can move horizontally along the axis direction of the fixed screw, so as to drive the connecting plate to move. Therefore, it can drive the horizontal bar tube to rotate and move horizontally at the same time, so as to comprehensively clean and spray the anti-slip coating on the horizontal bar tube.

[0021] The present invention can comprehensively grind and clean the horizontal bar tube that needs to be sprayed with the anti-slip coating, and then can evenly spray the anti-slip coating on the horizontal bar tube, so as to effectively avoid the problem of the sprayed coating falling off and avoid quality problems.

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0031] Embodiment 1: Refer to Figure 1-7, a spraying device, including a spraying box 1, in which a painting mechanism is installed. On one side of the spraying box 1, a support frame 11 is welded. A moving frame 13 is slidably arranged on the support frame 11. A driving mechanism is connected through the moving frame 13, and a single-bar tube 24 that needs to be sprayed with anti-slip coating is clamped on the driving mechanism.

[0032] The specific installation and working method of the painting mechanism are as follows: A bracket 2 is welded in the spraying box 1. An installation frame 3 is welded on the bracket 2. A delivery pump 4 is fixedly installed at the top of the installation frame 3 through bolts. The discharge end of the delivery pump 4 extends into the installation frame 3 and is welded with a spray plate 6. A delivery pipe 5 is welded on the suction end of the delivery pump 4. One end of the delivery pipe 5 is adhered with a hose 7, and the bottom end of the hose 7 extends into the spraying box 1. When the cleaned and polished single-bar tube 24 passes through the installation frame 3, the delivery pump 4 is started. The delivery pump 4 pumps out the anti-slip coating in the spraying box 1 from the hose 7. After being pressurized and delivered by the delivery pump 4, the anti-slip coating is delivered into the spray plate 6. The spray plate 6 is used to disperse and spray the anti-slip coating on the single-bar tube 24, realizing the uniform spraying of the anti-slip coating on the single-bar tube 24.

[0033] A plurality of positioning frames 8 are welded at equal intervals on the top of the bracket 2. The same reflector 9 is welded on the plurality of positioning frames 8. A plurality of baking lamp tubes 10 are fixedly installed at equal intervals through bolts at the bottom of the reflector 9. After the anti-slip coating is sprayed on the single-bar tube 24, the single-bar tube 24 moves to the lower part of the reflector 9. The plurality of baking lamp tubes 10 are powered on and lit. When the baking lamp tubes 10 emit light, they generate heat to dry the anti-slip coating, facilitating the rapid setting of the anti-slip coating on the single-bar tube 24.

[0034] The specific installation and working method of the driving mechanism are as follows: A driving motor 15 is fixedly installed on one side of the moving frame 13 through bolts. The output shaft of the driving motor 15 penetrates the moving frame 13 and is welded with a clamping cover 16. One end of the single-bar tube 24 extends into the clamping cover 16 and fits against the inner wall of the clamping cover 16. A plurality of positioning screws 17 are threadedly connected through the curved inner wall of the clamping cover 16 at equal intervals. The positioning screws 17 are used to clamp and position the single-bar tube 24. A connecting plate 18 is rotatably connected to the opening side of the clamping cover 16. A jack communicating with the clamping cover 16 is opened on the connecting plate 18. The single-bar tube 24 penetrates the jack. The connecting plate 18 is connected to the moving mechanism, and the bottom of the moving mechanism is sleeved on the clamping cover 16. After one end of the single-bar tube 24 that needs to be sprayed with anti-slip coating is inserted into the clamping cover 16, the single-bar tube 24 is positioned and braked by twisting the positioning screws 17. Then the driving motor 15 is started to drive the clamping cover 16 to rotate, driving the single-bar tube 24 to rotate. The rotating single-bar tube 24 can form a friction relationship with the cleaning mechanism, facilitating the cleaning of the single-bar tube 24. And when the clamping cover 16 rotates, it drives the moving mechanism to move, driving the single-bar tube 24 to move horizontally, so as to comprehensively polish and clean the single-bar tube 24 and spray the anti-slip coating.

[0035] Limit brackets 12 are welded on both sides of the support frame 11. A sliding plate 14 is slidably connected in the limit bracket 12. The two sliding plates 14 are respectively fixedly connected to both sides of the moving frame 13. When the moving frame 13 moves horizontally along with the moving mechanism, through the sliding fit between the sliding plate 14 and the corresponding limit bracket 12, the moving frame 13 is horizontally slidably supported, so that the moving frame 13 moves horizontally in a straight line.

[0036] The specific installation and working mode of the moving mechanism are as follows: It includes a fixed screw 20 connected to the grinding mechanism. One end of the fixed screw 20 is welded with a fixed frame 21. The fixed frame 21 is respectively welded to the two limit brackets 12. The top of one side of the connecting plate 18 is rotatably connected with a nut 19. The fixed screw 20 respectively penetrates through the connecting plate 18 and the nut 19 and is threadedly connected to the nut 19. A driving gear 22 is fixedly sleeved on the card cover 16 by welding. A driven gear 23 is fixedly sleeved on the nut 19 by welding. The driving gear 22 meshes with the driven gear 23. When the card cover 16 rotates, it drives the driving gear 22 to rotate. At this time, under the meshing drive of the driven gear 23, the nut 19 is driven to rotate. When the nut 19 rotates, under the threaded drive of the fixed screw 20, the nut 19 moves horizontally along the axis direction of the fixed screw 20, thereby driving the connecting plate 18 to move. Therefore, it can drive the single-bar pipe 24 to rotate and move horizontally at the same time, so as to comprehensively clean and spray anti-slip coating on the single-bar pipe 24.

[0037] This application can be used in the technical field of sports equipment production, and can also be used in other fields applicable to this application.

At this time, with the support and cooperation of the first grinding bent rod 26, the horizontal bar tube 24 is clamped, so that the two side grinding sandpapers are in close contact with the horizontal bar tube 24. Then, when the horizontal bar tube 24 rotates and moves, the grinding sandpapers are used to grind and clean the horizontal bar tube 24, so as to clean the floating dust and impurities adhering to the outer surface of the horizontal bar tube 24.

[0039] The specific installation and working mode of the threaded component are as follows: It includes a threaded ring 29 welded to the top of the equipment frame 25. A transmission screw rod 28 is threadedly connected through the threaded ring 29.
