Description

Technical Field

[0001] This invention belongs to the technical field of steel pipe dip coating equipment, specifically relating to a well-type steel pipe dip coating equipment for swirling dip coating attachment. Background Technology

[0002] Dip coating is a plastic coating process that involves heating the item to be dipped and then applying plastic powder or dip coating liquid to the surface of a substrate such as metal to form a plastic coating. According to the raw materials used in dip coating, it can be divided into liquid dip coating and powder dip coating. According to whether heating is required, it can be divided into hot dip coating and cold dip coating. This process does not require molds and has low processing costs, and is widely used in the surface treatment of products such as pipes, clothes hangers, guardrails, and hardware tools.

[0003] In the actual process of dip coating steel pipes, the preheated steel pipes are first hoisted and then sent into the dip coating equipment. At this time, the air compressor is turned on to blow compressed air into the dip coating equipment through the air distribution structure inside the equipment. The flowing compressed air will blow up the dip coating powder in the equipment, making it suspended. This dip coating powder can melt at the temperature of the steel pipe itself and evenly adhere to the surface of the steel pipe to form a dip coating layer.

[0004] However, during the dip coating process, since the steel pipe is generally stationary, the uniformity and thickness of its dip coating layer are affected by the degree of powder contact. When the steel pipe is long, the resistance to airflow inside the pipe increases significantly, resulting in weaker powder flow near the inner wall than the outer wall, which in turn affects the uniformity of the dip coating thickness between the inner and outer walls. In the existing technology, in order to alleviate the difference in the uniformity of the dip coating layer between the inner and outer walls of the steel pipe, vertical dip coating is generally used. However, during the vertical immersion and lifting process, the lower end of the steel pipe stays in the dip coating equipment for a significantly longer time than the upper end. This time difference can easily lead to differences in the thickness of the dip coating layer between the upper and lower ends of the steel pipe, thus affecting the dip coating quality. Summary of the Invention

[0005] The purpose of this invention is to provide a vortex-type steel pipe dip coating equipment to solve the technical problem of low uniformity of dip coating thickness on the inner and outer walls of the steel pipe and at both ends during the dip coating process.

[0006] To achieve the above objectives, embodiments of the present invention provide a vortex-type steel pipe dip coating equipment, comprising a dip coating shell and a support frame, wherein the dip coating shell is located at the bottom of the support frame, and a self-moving platform is provided on the support frame, and further comprising: A swirl air supply assembly is disposed inside the dip-coating housing and is used to deliver compressed air into the dip-coating housing to suspend the dip-coating powder inside the dip-coating housing. A lifting support frame is installed at the bottom of the self-moving platform; A hoisting adjustment component is provided on the lifting bracket for adjusting the position of the lifting bracket; The lifting and clamping assembly is provided at the bottom of the lifting bracket. It is used to clamp the steel pipe to be dipped and plasticized, and to move the steel pipe into the dip-plasticizing shell for dip-plasticizing.

[0007] To deliver compressed air into the dip-coated housing and suspend the powder, the swirling air supply assembly includes: An air distribution housing is fixedly mounted on the inner bottom wall of the dip-coated housing; The top of the air distribution shell is provided with a plurality of air distribution micropores at intervals; An air supply mechanism is provided on the air distribution housing, and the air supply mechanism is used to supply compressed air into the air distribution housing.

[0008] Furthermore, a plurality of secondary air distribution heads are fixedly connected to the air distribution housing. The plurality of secondary air distribution heads are arranged at equal distances along the edge of the air distribution housing. Each secondary air distribution head is arranged at an angle in the same direction. Each secondary air distribution head is provided with a plurality of air supply micro-holes at equal intervals.

[0009] To deliver compressed air into the air distribution housing, the air supply mechanism includes: An air intake filter and a blower, wherein the output end of the air intake filter is connected to the input end of the blower; An air supply pipe is provided, and the output end of the blower is connected to the input end of the air distribution housing through the air supply pipe.

[0010] To adjust the position of the lifting bracket, the hoisting adjustment assembly includes: A lifting drive component is fixedly mounted on the self-moving platform, and a mounting bracket is fixedly mounted on the output end of the lifting drive component; A hoisting mechanism is provided between the mounting frame and the lifting bracket to limit and adjust the position of the lifting bracket.

[0011] To limit and adjust the angle position of the lifting bracket, the hoisting mechanism includes: A hanging frame is fixedly installed at the bottom of the mounting frame; A rotating support is provided between the bottom of the suspended frame and the lifting bracket.

[0012] The bottom of the hoisting frame is rotatably equipped with an adjustment drive component, the output end of which is rotatably connected to the top of the lifting bracket, and a telescopic sleeve is fixedly installed between the hoisting frame and the lifting bracket.

[0013] To hold the steel pipe to be dipped in plastic coating, the lifting and clamping assembly includes: The clamping frame has two clamping frames that are slidably disposed at the bottom of the lifting bracket, and the two clamping frames are arranged symmetrically. The lifting bracket has two clamping drive components symmetrically and fixedly installed inside it, and the output ends of the two clamping drive components are respectively fixedly connected to the two clamping frames.

[0014] Furthermore, two guide rods are symmetrically arranged at the bottom of the lifting bracket, and the guide rods slide in cooperation with the clamping frame.

[0015] Furthermore, each of the two clamping frames is fixedly equipped with a conical clamping cylinder, the two conical clamping cylinders are arranged symmetrically, and the interior of each of the two conical clamping cylinders is provided with through grooves at equal angles in a circular shape.

[0016] The significant technical effects of the embodiments of the present invention are as follows: 1. The embodiment of the present invention provides a well-type steel pipe dip coating equipment for swirling dip coating. Air entering the air distribution shell is ejected through the air distribution micro-holes. At the same time, the air entering the air distribution shell enters the interior of the secondary air distribution head, and is distributed through the air supply micro-holes on the secondary air distribution head. Each secondary air distribution head is arranged inclined in the same direction. When the airflow is ejected from the air supply micro-holes on the secondary air distribution head, it will form a rotating and rising airflow field inside the dip coating shell along the inclined direction, thereby improving the uniformity of the dip coating powder suspension, and continuously agitating the powder, reducing channeling and dead zones in the powder suspension process, making the dip coating powder more evenly distributed throughout the shell, thereby improving the uniformity of the dip coating thickness between the inner and outer walls of the steel pipe.

[0017] 2. The vortex-type steel pipe dip coating equipment provided in this embodiment of the invention, through the setting of the adjustment drive component, can adjust the entry angle of the steel pipe when dip coating is required, so that the steel pipe enters the dip coating shell in an inclined state, thereby improving the uniformity of dip coating. After dip coating is completed, the adjustment drive component is turned on again to adjust the end of the steel pipe that was originally located at the bottom during dip coating to the top. Thus, during the process of the steel pipe being removed from the dip coating shell, the contact time between each part of the steel pipe and the dip coating powder tends to be consistent, compensating for the difference in dip coating layer thickness caused by the lower end of the steel pipe staying longer than the upper end during dip coating, thereby improving the uniformity of dip coating.

[0028] Please see Figures 1 to 4 This illustration shows a vortex-type steel pipe dip coating device according to an embodiment of the present invention, including a dip coating shell 1 and a support bracket 2. The dip coating shell 1 is located at the bottom of the support bracket 2, and a self-moving platform 3 is provided on the support bracket 2. It also includes a vortex air supply component, a lifting bracket 4, a hoisting and adjusting component, and a hoisting and clamping component. The vortex air supply component is disposed inside the dip coating shell 1 and is used to send compressed air into the dip coating shell 1, causing the dip coating powder inside the dip coating shell 1 to suspend like a boiling liquid. The vortex air supply component includes an air distribution shell 101, air distribution micropores 102, and an air supply mechanism, such as... Figure 3 , Figure 4 As shown, the air distribution housing 101 is fixedly installed on the inner bottom wall of the dip-coated housing 1. The top of the air distribution housing 101 is provided with a number of air distribution micro-holes 102 spaced apart. An air supply mechanism is provided on the air distribution housing 101 to supply compressed air into the air distribution housing 101. A number of secondary air distribution heads 103 are fixedly connected to the air distribution housing 101. The number of secondary air distribution heads 103 are all arranged at equal distances along the edge of the air distribution housing 101. Each secondary air distribution head 103 is arranged at an angle in the same direction, which can generate swirling airflow during the air distribution process. A number of air supply micro-holes 104 are provided at equal distances on each secondary air distribution head 103.

[0029] When steel pipes need to be dip-coated, the steel pipes are first preheated. Then, the steel pipes to be dip-coated are clamped by the hoisting and clamping assembly. The self-moving platform 3 is then activated, which moves the hoisting and adjusting assembly and the lifting bracket 4 to the dip-coating station. At this point, the steel pipe is directly above the dip-coating shell 1. The lifting bracket 4 is then lowered to place the steel pipe into the dip-coating shell 1. Simultaneously, the air supply mechanism is activated to inflate the air distribution shell 101. The air entering the air supply mechanism is ejected through the air distribution micro-holes 102, thus suspending the dip-coating powder inside the dip-coating shell 1. At the same time, the air entering the air distribution shell 101 enters the secondary air distribution head 103 and is distributed through the air supply micro-holes 104 on the secondary air distribution head 103. The orientation of the air supply micro-holes 104 on the secondary air distribution head 103 is as follows: Figure 4 As shown, each secondary air distribution head 103 is arranged at an angle in the same direction. When the airflow is ejected from the air supply micro-holes 104 on the secondary air distribution head 103, it will form a rotating and rising airflow field inside the dip-coating shell 1 along the inclined direction, thereby improving the uniformity of the dip-coating powder suspension, and continuously stirring the powder, reducing channeling and dead corners in the powder suspension process, and ensuring the uniformity of dip coating. After the dip coating is completed, the lifting and adjusting component is retracted, and the steel pipe after the dip coating is completed can be taken out and then moved to the next stage for processing.

[0030] The gas supply mechanism includes an air intake filter 105, a blower 106, and an air supply pipe 107, such as Figure 3 As shown, the output end of the air intake filter 105 is connected to the input end of the blower 106, and the output end of the blower 106 is connected to the input end of the air distribution housing 101 through the air supply pipe 107.

[0031] When in use, the blower 106 is turned on. The air entering the blower 106 is filtered and purified by the air intake filter device 105. The purified air enters the blower 106, is pressurized by the blower 106, and is then fed into the air distribution housing 101 through the air supply pipe 107, thereby providing a clean and stable air source for the air distribution housing 101.

[0032] The lifting support 4 is located at the bottom of the self-moving platform 3. A hoisting and adjusting assembly is installed on the lifting support 4 to adjust its position. The hoisting and adjusting assembly includes a lifting drive component 201 and a hoisting mechanism, such as... Figures 5 to 9 As shown, the lifting drive component 201 is fixedly mounted on the self-moving platform 3, and the output end of the lifting drive component 201 is fixedly mounted with a mounting bracket 202. The hoisting mechanism is located between the mounting bracket 202 and the lifting bracket 4 to limit and adjust the position of the lifting bracket 4.

[0033] When the self-moving platform 3 moves the entire hoisting and clamping assembly above the material handling station or the dip coating station, the lifting drive 201 can be activated after reaching the predetermined position. The lifting drive 201 drives the mounting frame 202 and the hoisting mechanism and lifting bracket 4 below it to descend or rise together, thereby adjusting the steel pipe to move up and down, and realizing the picking, placing and dip coating of the steel pipe.

[0034] During the dip coating process, the suspension mechanism can limit the swing of the lifting support 4 and adjust the spatial position of the lifting support 4 as needed during the dip coating process, so as to improve the uniformity of dip coating and the uniformity of contact between the inner and outer walls of the steel pipe and the dip coating powder.

[0035] The lifting mechanism includes a lifting frame 203 and a rotating support 204, such as Figure 7 , Figure 8 As shown, the hanging frame 203 is fixedly installed at the bottom of the mounting frame 202. A rotating support 204 is provided between the bottom of the hanging frame 203 and the lifting bracket 4. An adjustment drive 205 is rotatably installed at the bottom of the hanging frame 203. The output end of the adjustment drive 205 is rotatably connected to the top of the lifting bracket 4. A telescopic sleeve 206 is fixedly installed between the hanging frame 203 and the lifting bracket 4.

[0036] When the immersion angle of the steel pipe needs to be adjusted, the adjustment drive 205 is activated. The output end of the adjustment drive 205 pushes the lifting bracket 4. Since the lifting bracket 4 is rotatably connected to the hoisting frame 203 through the rotating support 204, the lifting bracket 4 will deflect around the fulcrum of the rotating support 204, thereby causing the hoisting clamping assembly and the steel pipe it clamps to change angle. During this process, the telescopic sleeve 206 expands and contracts with the change in distance between the lifting bracket 4 and the hoisting frame 203, thereby protecting the internal rotating support 204 and the adjustment drive 205 from dust contamination.

[0037] When the steel pipe needs to be dipped in plastic, the entry angle of the steel pipe can be adjusted so that the steel pipe enters the dip-coating shell 1 in an inclined state, thereby improving the uniformity of the dip coating. After the dip coating is completed, when the steel pipe needs to be lifted out of the dip-coating shell 1, the adjustment drive component 205 is activated again to adjust the end of the steel pipe that was originally located at the bottom during the dip coating to the top, that is, to make the steel pipe tilt in a different direction. In this way, during the process of the steel pipe being moved out of the dip-coating shell 1, the contact time between each part of the steel pipe and the dip coating powder tends to be consistent, thereby further improving the uniformity of the dip coating.

[0038] The bottom of the lifting support 4 is equipped with a hoisting clamping assembly for clamping the steel pipe to be dipped and moving it into the dip-coating housing 1 for dip-coating. The hoisting clamping assembly includes a clamping frame 301 and a clamping drive component 302. Figures 7 to 9As shown, two clamping frames 301 are slidably arranged at the bottom of the lifting bracket 4. The two clamping frames 301 are symmetrically arranged. Two clamping drive components 302 are symmetrically and fixedly arranged inside the lifting bracket 4. The output ends of the two clamping drive components 302 are fixedly connected to the two clamping frames 301 respectively. Two guide rods 303 are symmetrically arranged at the bottom of the lifting bracket 4. The guide rods 303 are slidably engaged with the clamping frames 301. Conical clamping cylinders 304 are fixedly arranged on both clamping frames 301. The two conical clamping cylinders 304 are symmetrically arranged. The inside of the two conical clamping cylinders 304 is circumferentially and has through grooves 305 at equal angles.

[0039] Among them, the lifting drive 201, the adjusting drive 205 and the clamping drive 302 are preferably all electric cylinders.

[0040] When it is necessary to clamp the preheated steel pipe, the two clamping drive units 302 are activated simultaneously. The output ends of the two clamping drive units 302 respectively push the two clamping frames 301 to move. The stability of the movement of the clamping frames 301 is improved by the setting of the guide rod 303. At this time, the two conical clamping cylinders 304 move synchronously with the clamping frames 301 and are gradually inserted into the pipe openings from both ends of the steel pipe. Since the conical clamping cylinders 304 have a conical surface structure, they can automatically center during the clamping process, thereby maintaining the stability of the steel pipe.

[0041] After the conical clamping cylinder 304 clamps the steel pipe, the dip coating powder can enter the interior of the steel pipe through the through groove 305, thereby reducing the dip coating blind zone of the clamping part. When the dip coating is completed and the dip-coated steel pipe is moved to the next stage, the clamping drive 302 is driven in the opposite direction, the two clamping frames 301 move in opposite directions, and the conical clamping cylinder 304 disengages from the steel pipe, completing the release.

[0042] When using a steel pipe dip coating equipment to perform dip coating operations on steel pipes, the steel pipes are first preheated, and then clamped. At this time, the lifting bracket 4 is moved to the material picking position, and then the two clamping drive components 302 are activated simultaneously. The output ends of the two clamping drive components 302 respectively push the two clamping frames 301 to move. The stability of the movement of the clamping frames 301 is improved by the setting of the guide rod 303. At this time, the two conical clamping cylinders 304 move synchronously with the clamping frames 301 and are gradually inserted into the pipe openings from both ends of the steel pipe. Since the conical clamping cylinders 304 have a conical surface structure, they can automatically center during the clamping process, thereby maintaining the stability of the steel pipe.

[0043] The self-moving platform 3 is activated, which moves the lifting and adjusting components and the lifting bracket 4 to the dip coating station. At this time, the steel pipe is directly above the dip coating shell 1. Then, the lifting drive 201 is activated, which moves the mounting frame 202 and the lifting mechanism and lifting bracket 4 below it down together. At this time, the adjusting drive 205 is activated, and the output end of the adjusting drive 205 pushes the lifting bracket 4. Since the lifting bracket 4 is rotatably connected to the lifting frame 203 through the rotating support 204, the lifting bracket 4 will deflect around the fulcrum of the rotating support 204, thereby causing the lifting clamping components and the steel pipe they clamp to change angle, so that the steel pipe enters the dip coating shell 1 in an inclined state, thereby improving the uniformity of dip coating, until the steel pipe to be dipped is placed into the dip coating shell 1.

[0044] At this time, the blower 106 is turned on. The air entering the blower 106 is filtered and purified by the air intake filter device 105. The purified air enters the blower 106, is pressurized by the blower, and then inputs into the air distribution housing 101 through the air supply pipe 107, thus providing a clean and stable air source for the air distribution housing 101. The air entering the air distribution housing 101 is ejected through the air distribution micropores 102, thereby keeping the plasticizing powder inside the plasticizing housing 1 in a suspended state. Simultaneously, the air entering the air distribution housing 101 enters the secondary air distribution head 103, thus passing through the secondary air distribution head 103. Air is distributed through the air supply micro-holes 104 on the primary air distribution head 103. Each secondary air distribution head 103 is arranged at an angle in the same direction. When the airflow is ejected from the air supply micro-holes 104 on the secondary air distribution head 103, it forms a rotating and rising airflow field inside the dip-coated shell 1 along the inclined direction, thereby improving the uniformity of the dip-coated powder suspension and continuously agitating the powder, reducing channeling and dead zones in the powder suspension process. At the same time, through the setting of the through groove 305, the dip-coated powder can enter the interior of the steel pipe through the through groove 305, thereby reducing the dip-coating blind zone of the clamping part and further ensuring the uniformity of dip-coating.

[0045] After the dip coating is completed, when the steel pipe needs to be lifted out of the dip coating shell 1, the adjustment drive 205 is activated again to adjust the end of the steel pipe that was originally at the bottom to the top, which is tilted during dip coating. This changes the tilt of the steel pipe, so that the contact time between each part of the steel pipe and the dip coating powder is more consistent during the process of moving the steel pipe out of the dip coating shell 1, thereby further improving the uniformity of dip coating. When dip coating is completed and the dip-coated steel pipe is moved to the next stage, the clamping drive 302 is driven in the opposite direction, the two clamping frames 301 move in opposite directions, and the conical clamping cylinder 304 disengages from the steel pipe, completing the release.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of protection of the claims of the present invention.
