Description

Technical Field

[0001] This invention relates to the field of chain impregnation machine technology, and more specifically, to a dripping paint recovery device and method for a chain impregnation machine. Background Technology

[0002] A paint dipping machine is a device used for dipping parts in paint. Its main function is to completely immerse the parts in paint liquid through chain conveyor, so that the surface of the parts is uniformly coated with a protective paint to improve the corrosion resistance, wear resistance and service life of the parts. In the traditional paint dipping process, problems such as paint dripping, serious waste and pollution of the working environment often occur. The paint dripping recovery device and method of the chain paint dipping machine involved in this invention are precisely to improve and innovate these problems, aiming to achieve efficient recovery and reuse of paint liquid, while reducing environmental pollution.

[0003] According to patent document CN115815041A, a vacuum impregnation machine is disclosed, comprising an impregnation machine housing, a rotary impregnation device inside the housing, a vacuum pump at the top of the housing connected to the top of the housing, a paint supply tank at the bottom of the housing containing paint liquid, and a paint supply pump at the bottom of the paint liquid connected to the bottom of the housing. The rotary impregnation device includes an active turntable and a driven turntable with opposite faces inside the housing. Multiple horizontally placed support rods are arranged circumferentially between the active and driven turntables. One end of each support rod is connected to the surface of the driven turntable, and the other end is connected to the surface of the active turntable. An impregnation coil is mounted on each support rod. This invention employs a vacuum impregnation machine with a rotary impregnation device, which improves impregnation efficiency and ensures effective impregnation results.

[0004] Chain-driven dipping paint machines use chains to transport parts to a dipping tank for painting, and then the parts are conveyed by chains to a drying area for drying. However, during the operation of traditional chain-driven dipping paint machines, due to the high speed of the chain and the fluidity of the paint, the paint often drips from the chain or parts. This not only leads to a large waste of paint and increases production costs, but also pollutes the working environment, affects the health of operators, and brings great difficulties to subsequent cleaning work. Summary of the Invention

[0011] As a further aspect of the present invention: the preliminary drying assembly includes two C-shaped side plates, with pipes fixedly connected to the middle of the outer sides of the two C-shaped side plates, and drying air outlet plates provided on the inner sides of the two C-shaped side plates.

[0012] As a further embodiment of the present invention: the conveying speed reduction mechanism includes two speed reduction mechanism base plates.

[0014] As a further embodiment of the present invention: the inner sides of the two sets of Y-shaped retractable crossbars are fixedly connected with retractable plates, and the left sides of the outer sides of the two retractable plates are fixedly connected to the inner sides of the two sets of second hinge blocks.

[0015] In addition, the present invention also relates to a paint dripping recovery device and method for a chain impregnation machine, comprising the following steps: Step 1: Hang multiple parts to be dipped in paint in sequence on the set position on one side of the chain conveyor belt through the fixing parts of the chain conveyor belt. Start the chain conveyor belt and make it start to run along the preset trajectory. The parts gradually fall into the inner wall of the dip paint tank as the chain conveyor belt moves. The dip paint process is completed in the dip paint tank to ensure that the paint liquid is fully and evenly attached to the surface of the parts. Step 2: As the chain conveyor belt continues to operate, the dipped parts are carried out of the dipping tank. At this time, the motor is started. Through the transmission of the L-shaped hinge block, rotating rod and hinge slider, the inclined rotating rod rotates in the shaft block, driving the C-shaped side plate and the drying air outlet plate on it to rotate to the front and rear sides of the top of the main body of the recycling tank. Step 3: The inclined feeding plate at the top of the recycling tank guides the paint dripping from the parts into the paint immersion tank, completing the initial recycling of the dripping paint. The splashed paint falls into the recycling tank. At the same time, the drying gas transmission box starts to work, and the drying gas enters the drying outlet plate through the pipe to perform preliminary drying treatment on the parts after immersion. Step 4: When the two sets of diagonal rotating rods rotate, they cause the Y-shaped hinge block and the second hinge block to change position. The change in position of the second hinge block causes the expansion and retraction plate to move. The expansion and retraction plate causes the Y-shaped expansion and retraction crossbar to rotate on the side block, realizing the expansion and retraction action of the Y-shaped expansion and retraction crossbar. This, in turn, pushes the two sets of abutment blocks to push the two sets of diagonal L-shaped side rods to move outward, so that the two rotating plates rotate around the inner side of the two sets of transition side plates as the axis and stand up. This slows down the speed and allows the track to fit more tightly with the parts, slowing down its movement speed through friction. Step 5: During the process of paint dripping recovery, initial drying, and slowing down the component conveying rate, continuously observe the recovery situation, drying effect, and component conveying status.

[0016] The beneficial effects of this invention are as follows: This invention organically combines three major functions—drip paint recovery, preliminary drying, and component conveying speed control—by incorporating a paint dipping tank, a chain conveyor belt, a drip paint recovery mechanism, and a conveying speed reduction mechanism. In terms of drip paint recovery, the cooperation between the recovery tank and the inclined feed plate effectively guides and initially recovers the dripping paint, avoiding paint waste and reducing environmental pollution. The addition of the preliminary drying function ensures the quality of the components after dipping and prevents parts from sticking together due to undried paint. Simultaneously, the conveying speed reduction mechanism allows for precise control of the component conveying speed on the chain conveyor belt during drip paint recovery, further improving the efficiency of drip paint recovery. This integrated design not only improves production efficiency but also reduces production costs, resulting in significant economic and social benefits. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figure 1-3 As shown, the present invention provides a dripping paint recovery device for a chain dipping paint machine, including a dipping paint tank 1, a chain conveyor belt 2 is provided on the top of the dipping paint tank 1, a dripping paint recovery mechanism 3 is fixedly connected to the right side of the dipping paint tank 1, and a conveying speed reduction mechanism 4 is provided on the right side of the dripping paint recovery mechanism 3. When parts need to be dipped in paint, multiple parts are first hung on one side of the chain conveyor belt 2 by the fixing parts of the chain conveyor belt 2, and then conveyed by the chain conveyor belt 2. The parts gradually fall into the inner wall of the paint dip tank 1 following the movement trajectory of the chain conveyor belt 2. After the paint dip process is completed in the paint dip tank 1, the parts are taken out of the paint dip tank 1 as the chain conveyor belt 2 continues to operate. At this time, the paint dripping recovery mechanism 3 starts to play its role. Since the parts have just come out of the paint dip tank 1, a lot of excess paint will be attached to the surface. This paint will drip down under the action of gravity. The paint dripping recovery mechanism 3 can accurately recover this dripping paint, avoiding the waste and environmental pollution caused by paint dripping randomly. In addition, the conveying speed reduction mechanism 4, through its unique internal structural design, precisely controls the conveying speed of the chain conveyor belt 2, so that the speed of the parts is reduced during the conveying process.

[0021] like Figure 3-9As shown, the paint dripping recovery mechanism 3 includes a recovery component 31. Preliminary drying components 32 are provided on both the front and rear sides of the recovery component 31. The recovery component 31 includes a control component 311. A recovery tank 312 is provided on the top of the control component 311. The control component 311 includes two inverted L-shaped side plates 3111. Inverted L-shaped support rods 3112 are fixedly connected to the left and right sides of the top outer sides of the two inverted L-shaped side plates 3111. A shaft block 3113 is fixedly connected to the top outer sides of the two sets of inverted L-shaped support rods 3112. Through slots 3114 are provided on the left and right sides of the top of the two inverted L-shaped side plates 3111. A motor 3115 is fixedly connected to the middle outer side of the front inverted L-shaped side plate 3111. The output end extends to the inner side of two inverted L-shaped side plates 3111 and is fixedly connected to a transmission disc 3116. A track 3118 is fitted onto the outer wall of the transmission disc 3116. Multiple columnar rotating rods 3117 are rotatably connected to the middle of the inner side of each of the two inverted L-shaped side plates 3111. Second transmission discs 3119 are fitted onto multiple sides of the inner wall of the track 3118. Second columnar rotating rods 31110 are fixedly connected to the inner walls of the multiple second transmission discs 3119. The front and rear ends of the multiple second columnar rotating rods 31110 are aligned with the inner ends of the front and rear sets of columnar rotating rods 3117. Elliptical rotating blocks 31111 are fixedly connected to the front and rear ends of the multiple second columnar rotating rods 31110 and the inner ends of the front and rear sets of columnar rotating rods 3117. Two sets of inverted L-shaped support rods 31... 12 has horizontal L-shaped connecting plates 31112 fixedly connected to the middle of its outer side. A drying gas transmission box 31113 is fixedly connected to the left side of the inner side of the two horizontal L-shaped connecting plates 31112. Connecting side plates 31114 are fixedly connected to the top of the two horizontal L-shaped connecting plates 31112 on their adjacent left sides. The right sides of the two connecting side plates 31114 are fixedly connected to the left side of the two inverted L-shaped side plates 3111. A support plate 31115 is fixedly connected to the bottom right side of the two inverted L-shaped support rods 3112 on the right side. The recycling pool 312 includes a recycling pool body 3121. Inclined feeding plate connecting side plates 3122 are fixedly connected to the front and rear sides of the top of the recycling pool body 3121. Inclined feeding plates 312 are fixedly connected to the inner side of the two inclined feeding plate connecting side plates 3122. 3. Connecting uprights 3124 are fixedly connected to both the left and right sides of the front and rear sides of the main body 3121 of the recycling pool. Lifting base plates 3125 are fixedly connected to the bottom of both sets of front and rear connecting uprights 3124. L-shaped hinge blocks 3126 are fixedly connected to the sides of the two lifting base plates 3125 that are close to each other. Rotating rods 3127 are rotatably connected to the outer sides of both sets of front and rear L-shaped hinge blocks 3126. Hinged sliders 3128 are rotatably connected to the sides of both sets of front and rear rotating rods 3127 that are away from the L-shaped hinge blocks 3126. Lifting rotating rods 3129 are rotatably connected to the top sides of the two lifting base plates 3125 that are close to each other. The top of the outer walls of both sets of front and rear lifting rotating rods 3129 are rotatably connected to the inner sides of multiple sets of elliptical rotating blocks 31111.The preliminary drying assembly 32 includes two C-shaped side plates 321. Pipes 322 are fixedly connected to the middle of the outer sides of each C-shaped side plate 321. Drying air outlet plates 326 are provided on the inner sides of each C-shaped side plate 321. Inclined rotating rods 323 are fixedly connected to the left and right sides of the outer sides of each C-shaped side plate 321. The middle of the outer walls of both sets of inclined rotating rods 323 are rotatably connected to the inner walls of both sets of shaft blocks 3113. Y-shaped hinge blocks 324 are rotatably connected to the bottom of the outer walls of both sets of inclined rotating rods 323. Second hinge blocks 325 are rotatably connected to the inner sides of both sets of Y-shaped hinge blocks 324. The bottom inner walls of the inner sides of both sets of inclined rotating rods 323 are slidably connected to the outer walls of both sets of hinge sliders 3128. When paint drippings need to be recycled, motor 3115 is started first. After motor 3115 starts, its output end drives the transmission disc 3116 to rotate. Since the track 3118 is fitted on the outer wall of the transmission disc 3116, the rotation of the transmission disc 3116 will drive the track 3118 to rotate synchronously. The multiple second transmission discs 3119 fitted on the inner wall of the track 3118 will rotate accordingly, thereby driving the second columnar rotating rod 31110, which is fixedly connected to the inner wall of the second transmission disc 3119, to rotate. The front and rear ends of the second columnar rotating rod 31110 are fixedly connected to the inner ends of the front and rear sets of columnar rotating rods 3117 through elliptical rotating blocks 31111. Therefore, the rotation of the second columnar rotating rod 31110 will drive the columnar rotating rod 3117 to rotate synchronously. The rotation of the columnar rotating rod 3117 causes the lifting rotating rod 3129 to rotate accordingly. The rotation of the lifting rotating rod 3129 drives the lifting base plate 3125 to move downward. When the base plate 3125 moves downward, it drives the entire recycling tank 312 to move downward. Through the transmission of the L-shaped hinge block 3126, the rotating rod 3127, and the hinge slider 3128, the inclined rotating rod 323 rotates within the shaft block 3113, thereby driving the C-shaped side plate 321 and its drying air outlet plate 326 to rotate. This causes the two C-shaped side plates 321 to rotate to the front and rear sides of the top of the recycling tank body 3121. At this time, the inclined feeding plate 3123 at the top of the recycling tank body 3121 guides the dripping paint into the paint immersion tank 1, completing the initial recycling of the dripping paint. The splashed paint falls into the recycling tank body 3121. At the same time as the recycling, the drying gas transmission box 31113 starts to work. The drying gas enters the drying air outlet plate 326 through the pipe 322 to perform preliminary drying treatment on the parts after immersion, preventing the paint from flowing excessively on the surface of the parts and causing waste. It also avoids the problem of parts sticking together due to the paint not being dry.

[0022] like Figure 10As shown, the conveying speed reduction mechanism 4 includes two reduction mechanism base plates 41. The bottoms of both reduction mechanism base plates 41 are fixedly connected to the front and rear sides of the top right side of the support plate 31115. A transition side plate 43 is fixedly connected to the left and right sides of the top of each of the two reduction mechanism base plates 41 on the side furthest from the top. A rotating plate 44 is rotatably connected to the inner side of each of the two sets of transition side plates 43. A speed reduction track 46 is rotatably connected to the top of each of the two rotating plates 44 on the side furthest from each other. The middle of the front sides of the two rotating plates 44... Each set of two sets of inclined L-shaped side rods 45 is fixedly connected to a stop block 47 on the outer side of each set of two sets of inclined L-shaped side rods 45 that are close to each other. The top of the two slowing mechanism base plates 41 is fixedly connected to the left and right sides of each side of each side that are close to each other. The outer side of each set of two sets of side blocks 42 is rotatably connected to a Y-shaped retractable crossbar 48. The inner side of each set of two sets of Y-shaped retractable crossbars 48 is fixedly connected to a retractable plate 49. The left side of each retractable plate 49 is fixedly connected to the inner side of each set of two sets of second hinge blocks 325. When the two sets of inclined rotating rods 323 rotate, they will cause the Y-shaped hinge block 324 and the second hinge block 325 to change position. The change in position of the second hinge block 325 causes the retractable plate 49 to move accordingly. The movement of the retractable plate 49 causes the Y-shaped retractable crossbar 48 to rotate on the side block 42, realizing the retractable action of the Y-shaped retractable crossbar 48. This causes the two sets of Y-shaped retractable crossbars 48 to move outward, thereby pushing the two sets of abutment blocks 47 outward and pushing the two sets of inclined L-shaped side rods 45 to move, thus causing the two rotating plates 4... 4. The two rotating plates 44 rotate around the inner side of the two sets of transition side plates 43, thereby making the two rotating plates 44 stand up. This allows the speed-reducing track 46 to fit more closely with the parts, and the friction slows down its movement speed. In this way, during the paint dripping recovery process, the precise control of the conveying speed of the parts on the chain conveyor belt 2 by the conveying speed reduction mechanism 4, combined with the recovery and preliminary drying functions of the paint dripping recovery mechanism 3, can effectively improve the paint dripping recovery efficiency, reduce paint waste and environmental pollution, and at the same time ensure the quality of the parts after dipping in paint.

[0023] In addition, the present invention also relates to a paint dripping recovery device and method for a chain impregnation machine, comprising the following steps: Step 1: Hang multiple parts to be dipped in paint in sequence on the set position on one side of the chain conveyor belt 2 through the fixing parts of the chain conveyor belt 2. Start the chain conveyor belt 2 so that it starts to run according to the preset trajectory. The parts gradually fall into the inner wall of the dip paint tank 1 as the chain conveyor belt 2 moves. The dip paint process is completed in the dip paint tank 1 to ensure that the paint liquid is fully and evenly attached to the surface of the parts. Step 2: As the chain conveyor belt 2 continues to operate, the dipped parts are carried out of the dipping tank 1. At this time, the motor 3115 is started. Through the transmission of the L-shaped hinge block 3126, the rotating rod 3127 and the hinge slider 3128, the inclined rotating rod 323 rotates in the shaft block 3113, which drives the C-shaped side plate 321 and the drying air outlet plate 326 on it to rotate to the front and rear sides of the top of the main body of the recycling tank 3121. Step 3: The inclined feeding plate 3123 at the top of the recycling pool body 3121 guides the paint dripping from the parts into the paint soaking tank 1, completing the initial recycling of the dripping paint. The splashed paint falls into the recycling pool body 3121. At the same time, the drying gas transmission box 31113 starts to work, and the drying gas enters the drying gas outlet plate 326 through the pipe 322 to perform preliminary drying treatment on the parts after soaking in paint. Step 4: When the two sets of inclined rotating rods 323 rotate, they drive the Y-shaped hinge block 324 and the second hinge block 325 to change position. The change in position of the second hinge block 325 causes the retractable plate 49 to move. The retractable plate 49 causes the Y-shaped retractable crossbar 48 to rotate on the side block 42, realizing the retractable action of the Y-shaped retractable crossbar 48. This pushes the two sets of abutment blocks 47 to push the two sets of inclined L-shaped side rods 45 to move outward, so that the two rotating plates 44 rotate around the inner side of the two sets of transition side plates 43 as the axis and stand up, allowing the track 46 to fit more tightly against the parts and slow down its movement speed through friction. Step 5: During the process of paint dripping recovery, initial drying, and slowing down the component conveying rate, continuously observe the recovery situation, drying effect, and component conveying status.

[0024] Working principle of this invention: When parts need to be dipped in paint, multiple parts are first hung on one side of the chain conveyor belt 2 via fixing parts, and then conveyed by the chain conveyor belt 2. The parts gradually fall into the inner wall of the dip paint tank 1 following the movement trajectory of the chain conveyor belt 2. After the dip paint process is completed in the dip paint tank 1, the parts are carried out of the dip paint tank 1 as the chain conveyor belt 2 continues to operate. At this time, the starter motor 3115 starts, and its output end drives the transmission disc 3116 to rotate. Since the track 3118 is sleeved on the outer wall of the transmission disc 3116, the rotation of the transmission disc 3116 will drive the track 3118 to rotate synchronously. Multiple second transmission discs 3119 fitted inside the inner wall of 118 rotate accordingly, thereby driving the second columnar rotating rod 31110, which is fixedly connected to the inner wall of the second transmission disc 3119, to rotate. The rotation of the second columnar rotating rod 31110 will drive the columnar rotating rod 3117 to rotate synchronously. The rotation of the columnar rotating rod 3117 will cause the lifting rotating rod 3129 to rotate accordingly. The rotation of the lifting rotating rod 3129 will drive the lifting base plate 3125 to move downward. When the lifting base plate 3125 moves downward, it will drive the entire recycling pool 312 to move downward. Through the transmission of the L-shaped hinge block 3126, the rotating rod 3127, and the hinge slider 3128, the inclined rotating rod 323 will rotate on the axis. The core block 3113 rotates, which in turn drives the C-shaped side plates 321 and their drying exhaust plates 326 to rotate, causing the two C-shaped side plates 321 to rotate to the front and rear sides of the top of the recycling tank body 3121. At this time, the inclined feeding plate 3123 on the top of the recycling tank body 3121 guides the dripping paint into the paint dipping tank 1, completing the initial recycling of the dripping paint. The splashed paint falls into the recycling tank body 3121. At the same time as recycling, the drying gas transmission box 31113 starts to work. The drying gas enters the drying exhaust plate 326 through the pipe 322 to perform preliminary drying treatment on the dipped parts, preventing the paint from flowing excessively on the surface of the parts and causing waste. When the two sets of inclined rotating rods 32 3. The rotation will cause the Y-shaped hinge block 324 and the second hinge block 325 to change position. The change in position of the second hinge block 325 causes the retractable plate 49 to move accordingly. The movement of the retractable plate 49 causes the Y-shaped retractable crossbar 48 to rotate on the side block 42, realizing the retractable action of the Y-shaped retractable crossbar 48. Thus, the two sets of Y-shaped retractable crossbars 48 move outward, thereby pushing the two sets of abutment blocks 47 outward and pushing the two sets of inclined L-shaped side bars 45 to move. This causes the two rotating plates 44 to rotate around the inner side of the two sets of transition side plates 43 as the axis, thereby causing the two rotating plates 44 to stand up, making the track 46 fit more tightly against the parts and slowing down its movement speed through friction.

10. A method of using a drip paint recovery device for a chain dipping machine according to any one of claims 1-9, characterized in that: Includes the following steps: Step 1: Hang the multiple parts to be dipped in paint in sequence on the set position on one side of the chain conveyor belt (2) through the fixing parts of the chain conveyor belt (2), start the chain conveyor belt (2) and make it start to run according to the preset trajectory. The parts gradually fall into the inner wall of the paint dipping tank (1) as the chain conveyor belt (2) moves. The paint dipping process is completed in the paint dipping tank (1) to ensure that the paint liquid is fully and evenly attached to the surface of the parts. Step 2: As the chain conveyor belt (2) continues to operate, the dipped parts are carried out of the dipping tank (1). At this time, the motor (3115) is started. Through the transmission of the L-shaped hinge block (3126), the rotating rod (3127) and the hinge slider (3128), the inclined rotating rod (323) rotates in the shaft block (3113), which drives the C-shaped side plate (321) and the drying air plate (326) on it to rotate to the front and rear sides of the top of the main body of the recycling tank (3121). Step 3: The inclined feeding plate (3123) at the top of the main body of the recycling pool (3121) guides the paint dripping from the parts into the paint soaking tank (1) to complete the initial recycling of the dripping paint. The spilled paint falls into the main body of the recycling pool (3121). At the same time, the drying gas transmission box (31113) starts to work, and the drying gas enters the drying outlet plate (326) through the pipe (322) to perform preliminary drying treatment on the parts after paint soaking. Step 4: When the two sets of inclined rotating rods (323) rotate, they drive the Y-shaped hinge block (324) and the second hinge block (325) to change position. The change in position of the second hinge block (325) causes the retractable plate (49) to move. The retractable plate (49) causes the Y-shaped retractable crossbar (48) to rotate on the side block (42), realizing the retractable action of the Y-shaped retractable crossbar (48). This pushes the two sets of abutment blocks (47) to push the two sets of inclined L-shaped side rods (45) to move outward, so that the two rotating plates (44) rotate around the inner side of the two sets of transition side plates (43) and stand up, allowing the speed-reducing track (46) to fit more closely with the parts, and slowing down its movement speed through friction. Step 5: During the process of paint dripping recovery, initial drying, and slowing down the component conveying rate, continuously observe the recovery situation, drying effect, and component conveying status.
