A surface painting apparatus for sports equipment manufacturing

Abstract

This invention discloses a surface painting device for sports equipment manufacturing, relating to the field of painting equipment. This surface painting device for sports equipment manufacturing utilizes an inwardly curved bottom end of an arc groove ring that engages with a concave arc surface below the nozzle. When paint is sprayed from the nozzle, some paint accumulates at the spraying position and is not sprayed out. As the accumulation increases, the paint slides outwards along the concave arc surface. The arc-shaped bottom end of the arc groove ring forms a groove, providing accumulation space for the sliding paint. This prevents paint from accumulating at the nozzle and dripping directly downwards onto the surface of the painted component, avoiding paint bumps after painting. Simultaneously, the concave arc surface guides the downward flow of paint, preventing it from accumulating at the spraying position and causing blockages after drying.

Description

Technical Field

[0001] This invention specifically relates to a surface painting device for sports equipment manufacturing, and pertains to the field of painting. Background Technology

[0002] Surface painting equipment for sports equipment manufacturing is an industrial equipment specifically used in the production process of sports equipment to spray paint, coat, spray and cure the surfaces of equipment such as metal, plastic and wood. A steel pipe painting processing equipment, with announcement number CN112774902B, includes a machine body, a receiving shaft, a painting device, and a paint storage box. The two ends of the receiving shaft are movably engaged with the two sides of the top of the machine body. The bottom end of the painting device is welded to the center of the top of the machine body. The bottom end of the paint storage box is embedded in the inside of the top of the painting device. The painting device includes a shell, a limiting ring, a painting block, a pushing block, and a clamping device. The bottom end of the painting block is embedded in the center of the bottom end inside the shell. The bottom end of the clamping device is movably engaged with the top of the pushing block. This invention transmits the steel pipe into the painting device through the receiving shaft. Under the limitation of the limiting ring, the steel pipe continues to move to the painting block for painting and is then sent out by the clamping device. When the clamping block of the clamping device contacts the steel pipe, the upper end of the receiving column inside is compressed and deformed, increasing the contact area and reducing the contact pressure. This prevents the painted steel pipe from being dented after being clamped, thus avoiding premature damage to the dented area during use. In existing equipment, the paint hardens after drying, blocking the nozzle's spray path and causing nozzle blockage. Additionally, when the rod rotates during painting, the center of the rotation axis shifts from the center of the rod's axis, causing the paint on the rod's surface to be easily flung off under centrifugal force. Summary of the Invention

[0003] To address the aforementioned problems, a technical solution is proposed: a surface painting device for sports equipment manufacturing, comprising: The frame has an oil pump and a water pump fixedly installed on its top, and a paint tank and a water tank installed on its two sides respectively. The oil pump's inlet is connected to the paint tank through a pipe, and the water pump's inlet is connected to the water tank through a pipe. A sprayer is fixedly installed on the top of the inner wall of the frame, and a painting mechanism is fixedly installed at the center of the top of the frame. A separation mechanism is fixedly installed on the outer side of the frame, and a fixing mechanism is fixedly installed on both sides of the inner wall of the frame. The painting mechanism includes a through-slot chamber. A guide pipe is fixedly installed on the top of the through-slot chamber, and the top end of the guide pipe passes through the frame and extends to its top. Circular through-slots are evenly distributed at the bottom of the through-slot chamber, and a fixed cylinder is fixedly installed at each of the circular through-slots. A nozzle is fixedly installed on the inner wall of the fixed cylinder, and an arc-groove ring is fixedly installed at the bottom of the fixed cylinder. The inward arc-shaped bend at the bottom of the arc-groove ring mates with the concave arc surface below the nozzle. When paint is sprayed from the nozzle, some paint accumulates at the spraying position and is not sprayed out. As the amount of paint increases, it slides down the concave arc surface to the surrounding areas. At this time, the bottom of the arc groove ring is curved to form a groove, providing a space for the sliding paint to accumulate. This prevents the paint from accumulating at the nozzle and dripping directly downwards onto the surface of the painted rod, which would cause paint bumps after the rod is painted. At the same time, the concave arc surface guides the paint to slide downwards, preventing it from accumulating at the spray position and causing blockage after drying. The bottom of the arc groove ring is curved inwards and is located below the nozzle, and the bottom of the nozzle is a concave arc surface.

[0004] Preferably, both sides of the through-slot chamber are provided with through slots, and a slag collection bin is fixedly installed at each through slot of the through-slot chamber. The top end of the guide pipe is fixedly connected to the outlet of the oil pump. An arc filter plate is fixedly installed on the inner wall of the through-slot chamber. The top of the arc filter plate is uniformly provided with filter holes, and the center of the top of the arc filter plate is arc-shaped and protruding. By utilizing the arc shape of the arc filter plate and the through slot of the through-slot chamber, while filtering the paint through the filter holes, the arc-shaped protrusion of the arc filter plate causes the intercepted clumps of foreign matter to move to both sides under the impact when the paint is subsequently introduced. Combined with the feature that the two sides of the top of the arc filter plate are flush with the bottom of the through slot of the through-slot chamber, the foreign matter passes through the through slot and enters the slag collection bin for collection, avoiding blockage. The two sides of the top of the arc filter plate are flush with the bottom of the through slot of the through-slot chamber.

[0005] Preferably, the fixing mechanism includes fixing plates, which are fixedly installed on both sides of the inner wall of the frame. Fixing columns are fixedly installed at the center positions of opposite faces of the fixing plates. A hollow slotted cylinder is fixedly installed at the end of each fixing column away from the fixing plate. A motor is fixedly installed on the inner wall of the hollow slotted cylinder. A turntable is rotatably installed at the end of the hollow slotted cylinder away from the fixing columns. The output end of the motor passes through the hollow slotted cylinder and extends to its outer side. The output end of the motor is fixedly connected to the non-opposing face of the turntable.

[0006] Preferably, a semi-cylinder is fixedly installed on each opposite side of the turntable. Perforated plates are provided on both sides of the semi-cylinder, and a sliding frame is slidably installed on the top of the semi-cylinder. Bolts are installed between the sliding frame and the semi-cylinder, and the sliding frame and semi-cylinder are fixedly connected by bolts. An inner convex plate is fixedly installed on the inner wall of the semi-cylinder. Through the cooperation of the inner convex plate and the arc pressure plate, when a rod is inserted, the symmetrical installation of the inner convex plate inside the semi-cylinder allows it to contact the bottom of both ends of the rod, thus positioning the rod. Simultaneously, after the arc pressure plate moves downwards... The rod is clamped and fixed by symmetrically arranged protrusions on the concave arc surface at the bottom of the arc pressure plate, while the inner convex plate is used to position the rod and prevent the paint spraying position from shifting, which would result in uneven paint spraying. The inner convex plate is symmetrically installed at the center of the axis of the semi-cylinder. An arc pressure block is fixedly installed at the bottom of the sliding frame. The bottom of the arc pressure block is a concave arc surface, and protrusions are provided on both sides of the bottom of the arc pressure block. The end of the semi-cylinder away from the turntable is evenly provided with notches.

[0007] Preferably, the separation mechanism includes an inner guide plate and a fixed frame. The inner guide plate is fixedly installed at the bottom of the inner wall of the frame, and the fixed frame is fixedly installed at the bottom of the outer side of the frame. The top of the inner guide plate is inclined, and the side near the fixed frame slopes downward. An oil collection tank is fixedly installed on the outer side of the fixed frame. The oil collection tank is flush with the top of the fixed frame. The inclined surface at the top of the inner guide plate guides the water-oil mixture to flow smoothly along the inclined surface at the top of the inner guide plate to the fixed frame. At the same time as the flow, the oil-water mixture is directly flushed into the fixed frame. When the liquid level in the fixed frame exceeds the highest position, the surface oil and some water enter the oil collection tank for collection and storage. The impact of the water flow impacts the liquid in the fixed frame, allowing the surface oil to smoothly enter the oil collection tank. A circular groove is provided at the bottom of the fixed frame, and an outlet pipe is fixedly installed in the circular groove of the fixed frame.

[0008] Preferably, a connecting frame is fixedly installed at the bottom of the inner wall of the fixed frame, a connecting shaft is slidably installed on the inner wall of the connecting frame, a hollow floating plate is fixedly installed at the top of the connecting shaft, and a blocking plate is fixedly installed at the bottom of the connecting shaft. The outer side of the blocking plate is slidably adapted to the circular groove of the fixed frame, and the bottom of the hollow floating plate is flush with the top of the fixed frame.

[0009] This invention provides a surface painting device for manufacturing sports equipment, which has the following beneficial effects: (i) By using the inward arc-shaped bend at the bottom of the arc groove ring to cooperate with the concave arc surface below the nozzle, when the nozzle sprays paint, some paint accumulates at the spraying position and is not sprayed out. As the accumulation increases, the paint slides down the concave arc surface to the surrounding areas. At this time, the arc-shaped bend at the bottom of the arc groove ring forms a groove to provide accumulation space for the sliding paint, preventing the paint from accumulating at the nozzle position and dripping directly downwards onto the surface of the painted rod, which would cause paint bumps to appear after the rod is painted. At the same time, the concave arc surface provides a guide for the paint to slide down, preventing it from always accumulating at the spraying position and causing blockage after drying.

[0010] (ii) By utilizing the arc shape of the arc filter plate and the through groove of the through groove, while filtering the paint through the filter holes, the arc-shaped convex surface of the arc filter plate causes the intercepted clumps of foreign matter to move to both sides under the impact when the paint is introduced. Combined with the fact that the top two sides of the arc filter plate are flush with the bottom of the through groove of the through groove, the foreign matter passes through the through groove and enters the slag collection bin for collection, thus avoiding blockage.

[0011] (III) By using the inner convex plate and the arc pressure plate together, when inserting the rod, the symmetrical installation of the inner convex plate inside the semi-cylinder allows it to contact the bottom of both ends of the rod to position the rod. At the same time, after the arc pressure plate moves down, the symmetrically arranged protrusions on the concave arc surface at the bottom of the arc pressure plate contact the top of both ends of the rod to clamp and fix the rod. In conjunction with the inner convex plate, the rod is positioned to avoid the paint position shift, which would result in uneven paint spraying of the rod.

[0012] (iv) The water-oil mixture is guided by the inclined surface at the top of the inner guide plate, so that it flows smoothly along the inclined surface at the top of the inner guide plate to the fixed frame. At the same time as the flow is guided, the oil-water mixture is directly flushed into the fixed frame. When the liquid level in the fixed frame exceeds the highest position, the surface oil and some water enter the oil collection tank for collection and storage. The impact of the water flow impacts the liquid in the fixed frame, so that the surface oil can smoothly enter the oil collection tank. Attached Figure Description

[0015] Example 1, Reference Figures 1 to 4 The present invention provides the following technical solution: A surface painting device for manufacturing sports equipment includes: The frame 1 has an oil pump 7 and a water pump 6 fixedly installed on its top. A paint tank 8 and a water tank 9 are installed on the two sides of the frame 1, respectively. The inlet of the oil pump 7 is connected to the paint tank 8 through a pipe, and the inlet of the water pump 6 is connected to the water tank 9 through a pipe. A sprayer 5 is fixedly installed on the top of the inner wall of the frame 1, and a painting mechanism 4 is fixedly installed at the center of the top of the frame 1. A separation mechanism 2 is fixedly installed on the outer side of the frame 1, and a fixing mechanism 3 is fixedly installed on both sides of the inner wall of the frame 1. The painting mechanism 4 includes a through-slot chamber 42. A guide pipe 41 is fixedly installed on the top of the through-slot chamber 42. The top end of the guide pipe 41 passes through the frame 1 and extends to its top. The bottom of the through-slot chamber 42 is evenly provided with circular through slots. A fixed cylinder 46 is fixedly installed at the circular through slot of the through-slot chamber 42. A nozzle 45 is fixedly installed on the inner wall of the fixed cylinder 46. The paint that passes through the arc filter plate 44 enters the nozzle 45 inside the fixed cylinder 46. After passing through the small paint flow path inside the nozzle 45, the paint is sprayed out from the concave arc surface at the bottom of the nozzle 45 to form an oil mist, which is used to paint the rod. An arc groove ring 47 is fixedly installed at the bottom of the fixed cylinder 46. The bottom end of the arc groove ring 47 is curved inward and is located below the nozzle 45. The bottom of the nozzle 45 is a concave arc surface.

[0016] Both sides of the through-slot chamber 42 are provided with through slots, and a slag collection chamber 43 is fixedly installed at each through slot of the through-slot chamber 42. The top end of the guide pipe 41 is fixedly connected to the outlet of the oil pump 7. An arc filter plate 44 is fixedly installed on the inner wall of the through-slot chamber 42. The guide pipe 41 is connected to the outlet of the oil pump 7, so that paint is introduced into the through-slot chamber 42 through the guide pipe 41. After the paint enters the through-slot chamber 42, the filter holes on the surface of the arc filter plate 44 block the agglomerated foreign objects in the paint. The convex arc surface on the top of the arc filter plate 44 is pushed by the subsequently introduced paint to move to the through slot positions on both sides of the through-slot chamber 42 and enter the slag collection chamber 43 for collection through the through slots. The top of the arc filter plate 44 is provided with filter holes evenly, and the center of the top of the arc filter plate 44 is arc-shaped and protruding. The two sides of the top of the arc filter plate 44 are flush with the bottom of the through slot of the through-slot chamber 42.

[0017] Example 2, based on Example 1, with reference to Figures 5 to 6 The fixing mechanism 3 includes a fixing plate 301, which is fixedly installed on both sides of the inner wall of the frame 1. Fixing posts 303 are fixedly installed at the center positions of opposite faces of the fixing plates 301. A slotted cylinder 302 is fixedly installed at the end of each fixing post 303 away from the fixing plate 301. A motor 305 is fixedly installed on the inner wall of the slotted cylinder 302. A turntable 304 is rotatably installed at the end of the slotted cylinder 302 away from the fixing post 303. When inserting the rod to be painted, both ends of the rod are inserted between the semi-cylindrical cylinder 306 and the sliding frame 309. After insertion, tighten bolt 307 with a wrench to lower the sliding frame 309, causing the inner convex plate 308 and the arc-pressing block 310 to move closer together. During this process, the inner convex plate 308 positions the rod. Due to the symmetrical installation of the inner convex plate 308 along the central axis inside the semi-cylinder 306, the inner convex plate 308 positions the rod at the center position inside the semi-cylinder 306. The output end of the motor 305 passes through the hollow slotted cylinder 302 and extends to its outer side. The output end of the motor 305 is fixedly connected to the non-opposing surface of the turntable 304.

[0018] A semi-cylinder 306 is fixedly installed on the opposite sides of the turntable 304. Perforated plates are provided on both sides of the semi-cylinder 306, and a sliding frame 309 is slidably installed on the top of the semi-cylinder 306. Bolts 307 are installed between the sliding frame 309 and the semi-cylinder 306, and the sliding frame 309 and the semi-cylinder 306 are fixedly connected by bolts 307. An inner convex plate 308 is fixedly installed on the inner wall of the semi-cylinder 306, and the inner convex plate 308 is symmetrically installed along the center position of the axis of the semi-cylinder 306. An arc-pressure block 310 is fixedly installed on the bottom of the sliding frame 309. During the rotation of bolt 307, the protrusions at the concave arc surface of the bottom of the arc-shaped block 310 contact both sides of the top of the rod and cooperate with the inner protruding plate 308 to clamp and fix the rod. During the painting process, motor 305 drives turntable 304 to rotate, which in turn drives semi-cylinder 306 to rotate, so that the rod is evenly painted during rotation. The bottom of the arc-shaped block 310 is a concave arc surface, and protrusions are provided on both sides of the bottom of the arc-shaped block 310. The end of the semi-cylinder 306 away from the turntable 304 is evenly provided with notches.

[0019] Example 3, based on Examples 1 and 2, with reference to Figures 7 to 9 The separation mechanism 2 includes an inner guide plate 21 and a fixed frame 22. The inner guide plate 21 is fixedly installed on the bottom of the inner wall of the frame 1, and the fixed frame 22 is fixedly installed on the bottom of the outer side of the frame 1. The top of the inner guide plate 21 is inclined, and the side near the fixed frame 22 is inclined downward. An oil collection tank 23 is fixedly installed on the outer side of the fixed frame 22. The oil collection tank 23 is flush with the top of the fixed frame 22. The inner guide plate 21 cooperates with the sprayer 5. The water mist curtain sprayed by the sprayer 5 blocks the oil mist from overflowing. At the same time, after the water mist comes into contact with the oil mist, it carries the oil mist down and falls on the top of the inner guide plate 21. The oil-water mixture on the top of the inner guide plate 21 is guided by the inclined surface of the inner guide plate 21 and slides down into the fixed frame 22. A circular groove is opened at the bottom of the fixed frame 22, and an outlet pipe 25 is fixedly installed at the circular groove of the fixed frame 22.

[0020] A connecting frame 24 is fixedly installed at the bottom of the inner wall of the fixed frame 22. A connecting shaft 28 is slidably installed on the inner wall of the connecting frame 24. A hollow float plate 26 is fixedly installed at the top of the connecting shaft 28, and a blocking plate 27 is fixedly installed at the bottom of the connecting shaft 28. After entering the fixed frame 22, it first accumulates in the fixed frame 22. At this time, the blocking plate 27 blocks the circular groove of the fixed frame 22, and the oil-water mixture cannot enter the outlet pipe 25. As the liquid level inside the fixed frame 22 continues to rise, after contacting the hollow float plate 26, the hollow float plate 26 floats up with the rise of the liquid level. At this time, the paint at the liquid level is guided to the oil collection tank 23 along with some water. At the same time, when the hollow float plate 26 rises, it drives the blocking plate 27 to move upward through the connecting shaft 28, so that the blocking plate 27 opens the circular groove of the fixed frame 22. The outer side of the blocking plate 27 slides and adapts to the circular groove of the fixed frame 22, and the bottom of the hollow float plate 26 is flush with the top of the fixed frame 22.

[0021] In use, the poles of the sports equipment to be painted are placed into the painting equipment. The poles are fixed by the fixing mechanism 3. The fixing mechanism 3 drives the poles to rotate at a constant speed during painting. During the rotation, the oil pump 7 drives the paint in the paint tank 8 into the painting mechanism 4, and sprays it out through the painting mechanism 4 to coat the surface of the poles. At the same time, the water pump 6 drives the water in the water tank 9 into the sprayer 5. The sprayer 5 forms a water mist curtain at the opening of the painting space to prevent the oil mist from spreading outward. After the water mist falls to the bottom of the painting space, it is introduced into the separation mechanism 2 for oil-water separation.

[0022] In the painting mechanism 4, the paint is connected to the outlet of the oil pump 7 through the guide pipe 41, so that the paint is introduced into the through slot chamber 42 through the guide pipe 41. After entering the through slot chamber 42, the filter holes on the surface of the arc filter plate 44 block the agglomerated foreign objects in the paint. With the push of the subsequently introduced paint, the paint moves to the through slot positions on both sides of the through slot chamber 42 through the slag collection chamber 43. At the same time, the paint passing through the arc filter plate 44 enters the nozzle 45 inside the fixed cylinder 46. After passing through the small paint flow path inside the nozzle 45, the paint is sprayed out from the concave arc surface at the bottom of the nozzle 45 to form an oil mist, which is used to paint the rod.

[0023] In the fixing mechanism 3, when the rod to be painted is installed, both ends of the rod are inserted between the semi-cylinder 306 and the sliding frame 309. After insertion, the bolt 307 is tightened with a wrench, causing the sliding frame 309 to move down. The inner convex plate 308 and the arc-pressing block 310 move closer to each other. During the approach, the inner convex plate 308 is used to position the rod. Due to the characteristic that the inner convex plate 308 is symmetrically installed along the center of the axis inside the semi-cylinder 306, the inner convex plate 308 positions the rod at the center position inside the semi-cylinder 306. During the rotation of the bolt 307, the protrusion at the concave arc surface of the bottom of the arc-pressing block 310 contacts the two sides of the top of the rod and cooperates with the inner convex plate 308 to clamp and fix the rod. During the painting process, the motor 305 drives the turntable 304 to rotate, which in turn drives the semi-cylinder 306 to rotate, so that the rod is painted evenly during the rotation.

[0024] In the separation mechanism 2, the inner guide plate 21 cooperates with the sprayer 5. The water mist curtain sprayed by the sprayer 5 blocks the oil mist from overflowing. At the same time, after the water mist comes into contact with the oil mist, it carries the oil mist down and lands on the top of the inner guide plate 21. The oil-water mixture on the top of the inner guide plate 21 is guided by the inclined surface of the inner guide plate 21 and slides down into the fixed frame 22. After entering the fixed frame 22, it first accumulates in the fixed frame 22. At this time, the blocking plate 27 blocks the circular groove of the fixed frame 22, and the oil-water mixture cannot enter the outlet pipe 25. As the liquid level inside the fixed frame 22 continues to rise, after contacting the hollow float plate 26, the hollow float plate 26 floats up with the rise of the liquid level. At this time, the paint at the liquid level is guided to the oil collection tank 23 along with some water. At the same time, when the hollow float plate 26 rises, it drives the blocking plate 27 to move upward through the connecting shaft 28, so that the blocking plate 27 opens the circular groove of the fixed frame 22.
