Description

Technical Field

[0001] This invention relates to the field of spray coating technology, and more specifically, to a fully automatic spray coating equipment for metal barrel walls. Background Technology

[0002] Metal drums are a common type of container widely used in industries such as chemicals, food, and paint. In the production process of metal drums, the spraying process is a crucial step in ensuring the appearance quality, corrosion resistance, and service life of the drums.

[0003] In existing metal drum coating equipment, the coating material tends to deposit on the traditional conveying device during spraying, affecting the coating effect. Specifically, during the spraying process, atomized paint particles scatter, and some paint falls onto the surface of the conveying device. As the spraying operation continues, the paint gradually deposits and solidifies on the conveying device, forming a coating that is difficult to remove. This deposited paint not only affects the surface finish and movement accuracy of the conveying device, but may also detach from the conveying device during subsequent spraying processes, falling onto the metal drum surface and forming impurities or particles, seriously affecting the coating quality and causing a decrease in product qualification rate.

[0004] Furthermore, paint deposits on the conveying device increase the operating resistance of the conveying mechanism, leading to increased motor load, increased energy consumption, and even jamming of the conveying mechanism, affecting the normal operation of the equipment. Secondly, cleaning these deposited paints requires a significant amount of labor and time, increasing maintenance costs and impacting production efficiency. Summary of the Invention

[0005] This invention provides a fully automatic metal drum wall spraying processing equipment, which solves the technical problem in related technologies where the deposition of spraying material on the conveying device during the conveying of metal drums affects the spraying effect and equipment operation.

[0006] This invention provides a fully automatic metal barrel wall spraying processing equipment, including a spraying device. The spraying device includes a paint mist separation chamber, with an inner spraying chamber and an outer spraying chamber respectively arranged on both sides of the paint mist separation chamber. The spraying device also includes a conveying chamber and a metal barrel conveying line. Both the inner and outer spraying chambers are equipped with intermittent conveying mechanisms for intermittently conveying the metal barrels. A metal barrel rotating mechanism is also provided on the path of the intermittent conveying mechanism for intermittently conveying the metal barrels, for driving the metal barrels to be sprayed to rotate, so that the spraying inside and outside the metal barrels is more uniform.

[0007] As a further optimization of the present invention, the intermittent conveying mechanism includes a first support frame disposed at the inlet end and outlet end of the inner spraying chamber and the outer spraying chamber. Each of the first support frames is provided with a sliding plate, and a first cylinder is mounted on the sliding plate. A lifting frame is mounted at the telescopic end of the first cylinder, and a conveying shaft is symmetrically mounted on the lifting frame. Multiple sets of push plates are disposed on the conveying shaft.

[0008] As a further optimization of the present invention, the multiple sets of push plates are arranged at equal intervals.

[0009] As a further optimization of the present invention, a first motor is installed on one of the first support frames, and a first swing arm is installed on the output shaft of the first motor. The end of the first swing arm away from the output shaft is rotatably connected to a second swing arm through a rotating shaft, and the end of the second swing arm away from the first swing arm is rotatably connected to a sliding plate through a rotating shaft.

[0010] As a further optimization of the present invention, the metal drum conveyor line extends outward from the inside of the conveying chamber, and the conveying part of the metal drum conveyor line is distributed at the inlet and outlet ends of the inner spraying chamber and the outer spraying chamber. At least two sets of bearing rods are also provided inside the inner spraying chamber and the outer spraying chamber, and the two ends of the bearing rods are rotatably connected to the outer frame of the corresponding metal drum conveyor line through bearings.

[0011] As a further optimization of the present invention, the metal barrel rotating mechanism includes a second support frame installed inside the inner spraying chamber and the outer spraying chamber respectively. The second support frame is provided with a fixed frame and a movable frame, and both the fixed frame and the movable frame are rotatably connected to rollers through bearings.

[0012] As a further optimization of the present invention, an internal spraying unit is provided on the internal spraying chamber. The internal spraying unit includes a lifting frame installed on the top of the internal spraying chamber. A third support frame is provided inside the lifting frame, and connecting rods are installed on both sides of the third support frame. The connecting rods pass through the interior of the internal spraying chamber and are connected to a spraying mechanism, which sprays the inner wall of the metal barrel.

[0013] As a further optimization of the present invention, the spraying mechanism includes a rotary cup body and a rotary cup spraying head, the rotary cup spraying head is assembled on the rotating end of the rotary cup body, and an adjustment component is provided between the rotary cup body and the connecting rod.

[0014] As a further optimization of the present invention, the adjustment component includes a static platform mounted on a connecting rod and a moving platform mounted on a rotating cup machine body. Both the static platform and the moving platform are triangular in structure. At each corner of the static platform, two sets of third cylinders are rotatably connected via universal joints, and the extension and retraction ends of the third cylinders are rotatably connected to the corners of the moving platform via universal joints.

[0015] As a further optimization of the present invention, an external spraying unit is provided inside the external spraying chamber. The external spraying unit includes a spraying frame installed inside the external spraying chamber, and an external spraying cantilever is installed on the rotating end of the spraying frame. The external spraying cantilever is used to spray the outer wall of the metal barrel.

[0016] The beneficial effects of this invention are as follows: This invention achieves continuous one-time spraying of the inner and outer walls of a metal drum by setting up an inner spraying chamber and an outer spraying chamber to spray the inner and outer walls of the metal drum respectively. This simplifies the process, improves production efficiency, and ensures the consistency of the coating on the inner and outer walls.

[0017] Secondly, the intermittent conveying mechanism enables precise intermittent movement of the metal bucket within the spraying chamber, effectively preventing issues of repeated or missed spraying. Simultaneously, the pusher plate of the intermittent conveying mechanism separates from the metal bucket during non-spraying periods, effectively reducing paint deposition on the conveying device and avoiding increased conveying resistance and decreased spraying quality caused by paint accumulation.

[0018] Furthermore, the rotating mechanism uses fixed and movable frames to set rollers respectively. The clamping force is adjusted by the second cylinder, and the second motor drives the rollers to rotate through the sprocket transmission mechanism. The drive synchronization is good and the rotation is smooth, which can effectively prevent the metal barrel from shifting or shaking during rotation, making the spraying more uniform.

[0019] In addition, the intermittent contact design between the push plate and the metal barrel effectively avoids the continuous deposition of paint on the conveying device, ensuring the long-term stable operation of the equipment. Attached Figure Description

[0022] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0023] According to the appendix Figure 1 To be continued Figure 3 As shown, this embodiment provides a fully automatic metal barrel wall spraying processing equipment, including a spraying device 100, which includes a paint mist separation chamber 110. An inner spraying chamber 120 and an outer spraying chamber 130 are respectively arranged on both sides of the paint mist separation chamber 110. A centrifugal fan 140 is installed on the paint mist separation chamber 110. The air inlet of the centrifugal fan 140 is connected to the inside of the paint mist separation chamber 110 for extracting the paint mist inside the paint mist separation chamber 110.

[0024] The centrifugal fan 140 is equipped with an exhaust filter box 150 at the exhaust end. The exhaust filter box 150 filters the gas discharged from the centrifugal fan 140. The purified gas meets the environmental emission standards before being discharged. This can effectively deal with the paint mist generated during the spraying process, reduce environmental pollution, and protect the health of operators.

[0025] The spraying device 100 also includes a conveying chamber 160, a metal barrel conveying line 170, an intermittent conveying mechanism 180, and a metal barrel rotating mechanism 190, which can realize fully automatic continuous spraying of the inner and outer walls of the metal barrel, significantly improving spraying efficiency and spraying quality.

[0026] According to the appendix Figure 4 and attached Figure 5 As shown, both the inner spraying chamber 120 and the outer spraying chamber 130 are equipped with intermittent conveying mechanisms 180 for intermittently conveying the metal drum.

[0027] The intermittent conveying mechanism 180 includes a first support frame 181 disposed at the inlet end and outlet end of the inner spraying chamber 120 and the outer spraying chamber 130. Each first support frame 181 is provided with a sliding plate 182, and a first cylinder 183 is mounted on the sliding plate 182. A lifting frame 184 is mounted at the telescopic end of the first cylinder 183, and conveying shafts 185 are symmetrically mounted on the lifting frame 184.

[0028] In a preferred embodiment, a slide rail is mounted on the first support frame 181, and a sliding sleeve is slidably connected to the slide rail. The sliding sleeve is fixedly connected to the sliding plate 182. The cooperation between the slide rail and the sliding sleeve makes the movement of the sliding plate 182 more stable and reliable, effectively reducing the impact and vibration during the movement process, and improving the accuracy and stability of intermittent conveying. The surfaces of the slide rail and the sliding sleeve can be treated with a non-stick coating to further reduce the adhesion of paint to their surfaces.

[0029] A first motor 186 is installed on one of the first support frames 181, and a first swing arm 187 is installed on the output shaft of the first motor 186. The end of the first swing arm 187 away from the output shaft is rotatably connected to a second swing arm 188 through a rotating shaft, and the end of the second swing arm 188 away from the first swing arm 187 is rotatably connected to a sliding plate 182 through a rotating shaft. Multiple sets of push plates 189 are provided on the conveying shaft 185.

[0030] Multiple sets of push plates 189 are arranged at equal intervals to ensure uniform pushing force on the metal barrel. A slide rail is installed on the first support frame 181, and a sliding sleeve is slidably connected to the slide rail. The sliding sleeve is fixedly connected to the sliding plate 182. Through the cooperation of the slide rail and the sliding sleeve, the movement of the sliding plate 182 is more stable and reliable.

[0031] In a preferred embodiment, the number and spacing of the push plates 189 can be adjusted according to the size of the metal bucket to accommodate different specifications of metal buckets. The push plates 189 are detachably connected, facilitating regular replacement and cleaning, and further reducing the impact of paint deposition on the spraying quality.

[0032] It should be specifically noted that when the intermittent conveying mechanism 180 is working, the first motor 186 drives the first swing arm 187 to rotate around the output shaft. The first swing arm 187 drives the second swing arm 188 to swing around the connection point through the rotating shaft. The second swing arm 188 drives the sliding plate 182 to slide horizontally on the slide rail. The sliding plate 182 drives the lifting frame 184 and the conveying shaft 185 to move horizontally. Multiple sets of push plates 189 on the conveying shaft 185 push the metal barrel forward one station.

[0033] After the metal bucket is moved into position, the first motor 186 rotates in the opposite direction, driving the sliding plate 182 and the push plate 189 to reset, ready to push the next metal bucket. After pushing the metal bucket into position, the push plate 189 separates from the metal bucket and is no longer in contact with it.

[0034] Meanwhile, the first cylinder 183 can drive the lifting frame 184 to move up and down, causing the conveying shaft 185 and the push plate 189 to rise or fall, thereby working with the first swing arm 187 and the second swing arm 188 to intermittently push the metal barrel and perform spraying processing on the metal barrel, effectively avoiding the problem of repeated or missed spraying.

[0035] Furthermore, the intermittent contact design between the pusher plate 189 and the metal bucket allows the pusher plate 189 to separate from the metal bucket during non-pushing periods, greatly reducing the deposition of paint on the pusher plate 189 and effectively avoiding the problems of increased conveying resistance and decreased spraying quality caused by paint deposition. Multiple sets of pushers 189 arranged at equal intervals ensure uniform pushing force on the metal bucket, preventing the metal bucket from shifting or tilting during movement.

[0036] Preferably, the metal drum conveyor line 170 extends outward from the inside of the conveying chamber 160, with the conveying portion of the metal drum conveyor line 170 located at the inlet and outlet ends of the inner spraying chamber 120 and the outer spraying chamber 130. At least two sets of support rods 1810 are also provided inside the inner spraying chamber 120 and the outer spraying chamber 130, and the two ends of the support rods 1810 are connected to the corresponding outer frame of the metal drum conveyor line 170 via bearings. The support rods 1810 support the metal drums, enabling them to move smoothly under the drive of the intermittent conveying mechanism 180. The bearing connection at both ends of the support rods 1810 reduces frictional resistance, making the movement and rotation of the metal drums smoother.

[0037] A metal drum rotating mechanism 190 is also provided on the path of the intermittent conveying mechanism 180 for intermittently conveying the metal drum, which is used to drive the metal drum to be sprayed to rotate, so that the spraying inside and outside the metal drum is more uniform.

[0038] According to the appendix Figure 6 As shown, the metal barrel rotating mechanism 190 includes a second support frame 191 installed inside the inner spraying chamber 120 and the outer spraying chamber 130 respectively. A fixed frame 192 and a movable frame 193 are provided on the second support frame 191. Rollers 194 are rotatably connected to both the fixed frame 192 and the movable frame 193 via bearings. The fixed frame 192 is fixed to the second support frame 191, and a second cylinder 195 is installed on the movable frame 193. The extension and retraction ends of the second cylinder 195 are fixedly connected to the inner walls of the inner spraying chamber 120 and the outer spraying chamber 130 respectively.

[0039] Furthermore, a telescopic frame is provided between the fixed frame 192 and the movable frame 193, and a second motor 196 is installed on the telescopic frame. The fixed frame 192 is connected to the rollers 194 on both sides through a sprocket transmission mechanism.

[0040] It is important to note that the telescopic frame is equipped with a sprocket tensioning mechanism inside. This mechanism adjusts the tension of the sprocket drive mechanism as the frame extends or retracts. This internal mechanism automatically adjusts the tension of the sprocket drive mechanism according to the frame's position, ensuring good transmission performance in all positions and preventing tooth skipping or slippage.

[0041] It should be noted that when the metal barrel rotating mechanism 190 is working, the second cylinder 195 drives the movable frame 193 to move horizontally, so that the roller 194 on the movable frame 193 moves closer to or further away from the roller 194 on the fixed frame 192, thereby adjusting the clamping force on the metal barrel.

[0042] When it is necessary to clamp the metal bucket, the second cylinder 195 pushes the movable frame 193 to move, so that the rollers 194 on both sides clamp the metal bucket in the middle position.

[0043] After clamping is completed, the second motor 196 drives the sprocket transmission mechanism to rotate. The sprocket transmission mechanism simultaneously drives the rollers 194 on the fixed frame 192 and the movable frame 193 to rotate. The rollers 194 drive the metal barrel to rotate through friction.

[0044] The rollers 194 on the fixed frame 192 and the movable frame 193 are driven simultaneously, with good drive synchronization, which can effectively prevent the metal barrel from shifting or shaking during rotation.

[0045] According to the appendix Figure 7 To be continued Figure 9As shown, an inner spraying unit 200 is provided on the inner spraying chamber 120. The inner spraying unit 200 includes a lifting frame 210 installed on the top of the inner spraying chamber 120. A third support frame 220 is provided inside the lifting frame 210, and connecting rods 230 are installed on both sides of the third support frame 220. The connecting rods 230 pass through the inside of the inner spraying chamber 120 and are connected to a spraying mechanism 240. The spraying mechanism 240 sprays the inner wall of the metal barrel.

[0046] The lifting frame 210 is equipped with a third motor 250. Inside the lifting frame 210, a shaft is rotatably connected via bearings. The output shaft of the third motor 250 passes through the lifting frame 210 and is connected to the shaft via a sprocket transmission mechanism. The third support frame 220 is installed on a chain on one side of the sprocket transmission mechanism. Inside the lifting frame 210, a guide rail is installed, and a guide sleeve is slidably connected to the guide rail. The guide sleeve is fixedly connected to the third support frame 220.

[0047] It should be noted that when the inner spraying unit 200 is operating, the third motor 250 drives the sprocket transmission mechanism to rotate. The sprocket transmission mechanism drives the third support frame 220 to move up and down along the guide rail, thereby adjusting the height of the spraying mechanism 240 to accommodate metal drums of different heights. The connecting rod 230 connects the third support frame 220 to the spraying mechanism 240, allowing the spraying mechanism 240 to move up and down with the third support frame 220, achieving precise spraying of the inner wall of the metal drum. The cooperation of the guide rail and guide sleeve makes the up and down movement of the third support frame 220 more stable and reliable, ensuring the accuracy of the spraying position.

[0048] The spraying mechanism 240 includes a rotary cup body 241 and a rotary cup spray head 242. The rotary cup spray head 242 is mounted on the rotating end of the rotary cup body 241. An adjustment assembly 243 is provided between the rotary cup body 241 and the connecting rod 230. Radar sensors 245 are symmetrically mounted on the rotary cup body 241, and the radar sensors 245 are horizontally positioned with respect to the lower surface of the rotary cup spray head 242, for detecting the levelness of the sprayed material.

[0049] The rotary cup spray head 242 is a high-speed rotating atomizing spray head. Under the action of centrifugal force, the paint is atomized into fine droplets, enabling efficient and uniform spraying. The radar sensor 245 is used to detect the levelness of the inner wall of the metal drum in real time. When the tilt of the inner wall of the metal drum is detected, the signal is fed back to the adjustment component 243 for adjustment to ensure the consistency of the spraying.

[0050] In a preferred embodiment, the radar sensor 245 employs a non-contact measurement method, enabling it to detect the levelness of the inner wall of the metal drum in real time and accurately, and feeds the detection signal back to the control system. The control system, based on the signal, controls the six third cylinders 2433 of the six-degree-of-freedom motion table to perform corresponding extension and retraction adjustments, maintaining the horizontal state of the spray head and ensuring consistent spraying quality.

[0051] According to the appendix Figure 9 and attached Figure 10 As shown, the adjustment assembly 243 includes a stationary platform 2431 mounted on the connecting rod 230 and a moving platform 2432 mounted on the rotating cup body 241. Both the stationary platform 2431 and the moving platform 2432 are triangular in structure. At each corner of the stationary platform 2431, two sets of third cylinders 2433 are rotatably connected via universal joints, and the extension and retraction ends of the third cylinders 2433 are rotatably connected to the corners of the moving platform 2432 via universal joints.

[0052] The static platform 2431, the moving platform 2432, and multiple sets of third cylinders 2433 constitute a six-degree-of-freedom motion table, which is used to adjust the horizontal position of the rotary cup machine body 241 to avoid uneven thickness caused by tilted spraying when the surface of the object being sprayed is inclined, resulting in one side being thick and the other thin, thus ensuring consistent spraying.

[0053] The adjustment component 243 is provided with a protective sleeve 244. The two ends of the protective sleeve 244 are respectively installed on the static platform 2431 and the moving platform 2432 to protect the internal mechanical structure and prevent paint contamination and mechanical damage.

[0054] In a preferred embodiment, the protective sleeve 244 is made of a flexible material, which can adapt to various movement postures of the adjustment component 243, while effectively preventing paint from splashing into the internal mechanism, ensuring the reliability and service life of the mechanical structure.

[0055] It is important to understand that when the adjustment component 243 is in operation, the moving platform 2432 can be adjusted to any position and orientation in three-dimensional space by controlling the extension and retraction of the six third cylinders 2433. When the radar sensor 245 detects a tilt in the inner wall of the metal barrel, the control unit calculates the required adjustment amount based on the detection signal and controls each third cylinder 2433 to extend and retract accordingly, keeping the rotary cup machine body 241 and the rotary cup spray head 242 in a horizontal state, thereby achieving uniform spraying. This design greatly improves the adaptability of the equipment, enabling it to handle metal barrels with various degrees of tilt and ensuring consistent spraying quality.

[0056] According to the appendix Figure 3As shown, an external spraying unit 300 is provided inside the external spraying chamber 130. The external spraying unit 300 includes a spraying frame 310 installed inside the external spraying chamber 130, and an external spraying cantilever 320 is installed on the rotating end of the spraying frame 310. The external spraying cantilever 320 is used to spray the outer wall of the metal barrel.

[0057] It should be noted that when the external spraying unit 300 is working, the spraying frame 310 drives the external spraying cantilever 320 to rotate. The external spraying cantilever 320 is equipped with a spray gun head, which performs circular spraying along the outer wall of the metal barrel. Driven by the metal barrel rotation mechanism 190, the metal barrel continues to rotate, and the external spraying cantilever 320 performs all-round spraying on the outer wall of the metal barrel to achieve uniform coverage.

[0058] According to the appendix Figure 1 To be continued Figure 10 As shown, the working principle of the fully automatic metal drum coating equipment is as follows: During operation, the metal drum is first placed on the metal drum conveyor line 170 inside the conveying chamber 160. The metal drum conveyor line 170 transports the metal drum to the inlet end of the inner coating chamber 120.

[0059] After the metal drum enters the inner spraying chamber 120, the intermittent conveying mechanism 180 inside the inner spraying chamber 120 starts to work.

[0060] The first motor 186 of the intermittent conveying mechanism 180 drives the first swing arm 187 to rotate. The first swing arm 187 drives the second swing arm 188 to swing. The second swing arm 188 drives the sliding plate 182 to slide on the slide rail. The sliding plate 182 drives the lifting frame 184 and the conveying shaft 185 to move. The push plate 189 on the conveying shaft 185 pushes the metal barrel forward one station.

[0061] Once in place, the pusher plate 189 separates from the metal drum, and the intermittent conveying mechanism 180 pauses, waiting for the spraying to complete. During the intermittent conveying process, the intermittent contact design between the pusher plate 189 and the metal drum effectively reduces the deposition of spray paint on the pusher plate 189, ensuring the cleanliness and smooth operation of the conveying mechanism.

[0062] While the intermittent conveying mechanism 180 is moving the metal drum, or after the drum has moved into position, the metal drum rotating mechanism 190 begins to operate. The second cylinder 195 drives the roller 194 on the movable frame 193 to move closer to the metal drum. After the roller 194 clamps the metal drum, the second motor 196 drives the sprocket transmission mechanism to rotate. The sprocket transmission mechanism drives the roller 194 to rotate, and the roller 194 drives the metal drum to rotate continuously through friction.

[0063] The internal spraying unit 200 begins operation. The adjustment assembly 243 adjusts the levelness of the rotary cup machine body 241 and the rotary cup spray head 242 based on the detection signal from the radar sensor 245, ensuring uniform spraying. The rotary cup spray head 242 performs high-speed centrifugal atomization spraying on the inner wall of the metal drum, evenly covering the inner wall with paint. With the continuous rotation of the metal drum and intermittent conveying, every part of the inner wall of the metal drum receives uniform spraying.

[0064] After the inner wall is coated, the intermittent conveying mechanism 180 continues to push the metal drum forward, moving it to the outlet end of the inner coating chamber 120. During the movement, the metal drum rotation mechanism 190 continuously drives the metal drum to rotate, ensuring the integrity of the coating.

[0065] Then, the metal drum is conveyed to the inlet of the outer spraying chamber 130 via the metal drum conveyor line 170. The intermittent conveying mechanism 180 and the metal drum rotation mechanism 190 inside the outer spraying chamber 130 begin operation, cooperating with the outer spraying unit 300 to spray the outer wall of the metal drum. The outer spraying cantilever 320 rotates under the drive of the spraying frame 310, and the spray gun head performs a circular spray on the outer wall of the metal drum. While the metal drum continues to rotate, the intermittent conveying mechanism 180 drives the metal drum to move intermittently, and the outer spraying cantilever 320 performs all-around spraying on the outer wall of the metal drum, achieving uniform coverage.

[0066] After the outer wall is coated, the intermittent conveying mechanism 180 moves the metal bucket to the outlet end of the outer coating chamber 130 to complete the entire coating process.

[0067] Throughout the spraying process, the paint mist treatment system, consisting of the paint mist separation chamber 110, the centrifugal fan 140, and the exhaust filter box 150, works continuously to extract and filter the paint mist inside the inner spraying chamber 120 and the outer spraying chamber 130, ensuring a clean and environmentally friendly production environment.

[0068] The embodiments of this specific implementation have been described above. However, this embodiment is not limited to the specific implementation described above. The specific implementation described above is merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this embodiment, all of which are within the protection scope of this embodiment.
