A buffer tank liner welding device

Abstract

The application belongs to the technical field of buffer tank inner container welding, in particular to a buffer tank inner container welding device, which comprises an operation box, a moving mechanism arranged at the back of the operation box and an inner container placed on the moving mechanism, further comprising a welding mechanism arranged at one side of the moving mechanism and an auxiliary alignment mechanism symmetrically arranged at the outer side of the moving mechanism. The auxiliary alignment mechanism is arranged to make the inner container adhere to the surface of the inner container through the air between the suction adsorption assembly and the inner container, so as to realize the gripping force on the surface of the inner container and keep the inner container stable during rotation. In the process of rotating the inner container, the adsorption assembly is driven to rotate along the fixed sliding groove, so that the gap of the inner container close to the welding head part is kept in a close-fitting state, avoiding deviation during the process of driving the inner container to roll, which leads to the expansion of the gap, thereby causing a larger weld or inner container leakage, resulting in processing failure. The detection assembly further judges whether the inner container is in a correct alignment state, thereby improving the welding precision.

Description

Technical Field

[0001] This invention belongs to the field of buffer tank liner welding technology, specifically a buffer tank liner welding equipment. Background Technology

[0002] Buffer tanks are mainly used in various systems to buffer pressure fluctuations, making the system operate more smoothly. The buffering performance of a buffer tank is mainly achieved by compressing the air inside the tank. Some existing buffer tanks are made of plastic. These buffer tanks are produced in two ways: one-piece molding and welded molding. When welding buffer tanks made of plastic, infrared welding equipment is usually used.

[0003] Most existing infrared welding equipment is automated. The outer diameter of the inner liner of the buffer tank that one machine is used for must be consistent, and the length can be adjusted within a certain range. Since the outer diameter of the welding object is consistent, the complexity of the welding action of the equipment during infrared welding can be reduced. However, it is not possible to keep the inner liner in close contact during the connection process, which can cause the inner liner to shift during the flipping process, resulting in the welding not being able to accurately align the inner liner. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this invention is: a buffer tank inner liner welding device, comprising an operation box, a moving mechanism disposed behind the operation box, and an inner liner placed on the moving mechanism, and further comprising: A welding mechanism is located on one side of the moving mechanism, and auxiliary alignment mechanisms are symmetrically located on the outside of the moving mechanism; The auxiliary alignment mechanism includes a fixed slide groove and a second slider disposed inside the fixed slide groove, a hydraulic rod mounted on one side of the second slider and an adsorption assembly mounted on the side of the hydraulic rod away from the second slider, and a detection assembly slidably connected to the outside of the fixed slide groove.

[0005] Furthermore, the moving mechanism includes: A base plate, on which slide rails are symmetrically arranged; A movable seat that slides along a slide rail on a base plate; The drive wheels are symmetrically arranged above the movable seat. The outer side of the drive wheels is in contact with the outer side of the inner liner. The rotation of the drive wheels drives the inner liner to rotate coaxially on the movable seat and is then welded together.

[0006] Furthermore, the welding mechanism includes: A base, wherein the base is disposed on one side of the base plate; A fixing plate, which is mounted on top of the base; Support arm, which is mounted above the fixed plate.

[0007] Furthermore, the welding mechanism also includes: A welding head, which is mounted at the other end of the support arm; A protective component is slidably connected to the outside of the support arm and covers the outside of the welding head.

[0008] Furthermore, the protective component includes: The first slider is slidably connected to the outside of the support arm; A fixed frame is provided, the interior of which is connected to the exterior of the first slider. The position of the fixed frame is fixed relative to the first slider, and it remains stationary during use, allowing the extension frame to hang down naturally. An extension frame is installed on the side of the fixed frame near the welding head. The extension frame is a metal louvered plate that hangs down naturally to contact the inner liner surface during use, blocking the welding position.

[0009] Furthermore, the protective component also includes: An arc-shaped tube is installed inside a fixed frame. The arc-shaped tube is rotatably connected inside the fixed frame. When in use, the arc curves downward, allowing the arc-shaped rod to extend downward naturally, thus unfolding the extension frame. An arc-shaped rod is installed inside an arc-shaped tube. One end of the arc-shaped rod is equipped with an elastic rope, and the other end of the elastic rope is connected to the inside of the arc-shaped tube. The arc-shaped rod extends and retracts inside the arc-shaped tube. When the opening of the arc-shaped tube is downward, it naturally extends and drives a baffle to block the extension frame, so that the extension frame rests on the arc-shaped rod and moves. When the arc-shaped tube rotates 180 degrees and the opening is upward, the arc-shaped rod retracts and drives the extension frame to retract. A baffle plate is mounted on the other end of the arc-shaped rod.

[0010] Further, the adsorption component includes: A movable block is installed at the other end of a hydraulic rod, and an air outlet channel is provided inside the movable block. A branch pipe passes through the interior of the movable block, and one end of the branch pipe is connected to a suction cup. The surface of the suction cup has a certain thickness of latex, so that when the suction cup naturally approaches the surface of the inner liner, it conforms to the curvature of the inner liner surface, creating a negative pressure inside the suction cup to adhere to the surface of the inner liner.

[0011] Furthermore, the adsorption component also includes: A sealing box is installed above the movable block, and the other end of the branch pipe is connected to the top of the sealing box; The lifting rod is installed inside the sealed box; A stopper plate is installed above the lifting rod. The outside of the stopper plate is in contact with the inside of the sealing box. The lifting rod and the stopper plate are used together to form a piston inside the sealing box. The gas is drawn up to create a negative pressure, and the gas is filled in and pressurized from the bottom. The gas can also be reversed.

[0012] Furthermore, the adsorption component also includes: A connecting pipe is installed on the outside of the movable block and is connected to the air outlet channel; An inflation ring is located at the other end of the connecting tube. The outside of the inflation ring is in contact with the outside of the suction cup. The inflation ring is made of rubber and expands after inflation, pressing the surface of the suction cup to make it fit the surface of the inner liner more closely.

[0013] Furthermore, the detection component includes: A housing, which is slidably connected to the outside of a fixed slide groove; The telescopic rod is installed inside the housing. A connecting block is provided at the other end of the telescopic rod. The connecting block is slidably connected inside the housing. A contact sensor is provided inside the connecting block, which cooperates with the support rod to determine whether the inner liner has shifted during the movement. A spring is mounted on the other side of the connecting block; The probe is mounted on the other end of the spring, and a support rod is provided on the side of the probe near the spring; A sensor is positioned on the opposite side of the probe.

[0014] The beneficial effects of this invention are as follows: 1. This invention, by setting up an auxiliary alignment mechanism, draws air from between the adsorption component and the inner liner, causing them to adhere to the surface of the inner liner. This achieves a gripping force on the inner liner surface, keeping the inner liner stable during rotation. As the inner liner rotates, it drives the adsorption component to rotate along a fixed groove, maintaining a tight fit around the inner liner seam near the welding head. This prevents displacement during the rolling of the inner liner by the drive wheel, which could lead to widening of the seam, resulting in a larger weld or incomplete welding of the inner liner, causing processing errors. The detection component measures the outer diameter of the two halves of the inner liner during rotation, determining whether the outer circular surfaces of the inner liner are still on the same horizontal line after rotation before welding. This further determines whether the inner liner is in a correct alignment state, improving welding accuracy.

[0015] 2. The present invention sets up a welding mechanism in which the support arm drives the welding head close to the inner liner, and then the drive wheel drives the inner liner to rotate, so that the welding head welds the gap of the inner liner. At the same time, the protective component covers the welding part, reducing the slag generated during welding from splashing outwards, and blocking the light from welding, so as to prevent impurities generated during welding from adhering to the surface of the inner liner.

[0016] 3. This invention incorporates a protective component. The arc-shaped tube rotates so that the opening faces downward, causing the arc-shaped rod to fall downward and naturally hang down from the extension frame, contacting the surface of the inner liner to form a closed space. This encloses the welding area, reducing slag splashing outward. After welding, the arc-shaped tube rotates so that the opening faces upward, placing the end of the extension frame at a higher position. Then, due to gravity, it automatically falls back to the vicinity of the fixed frame to complete the winding. This facilitates automatic adjustment of the welding space enclosed by the extension frame and the fixed frame, concentrating the space around the welding area, making it easier to collect the gas and slag generated during welding, and reducing the adhesion of slag to the surface of the inner liner.

[0017] 4. This invention, by setting up an adsorption component, draws air from the suction cup and the vicinity of the inner liner into the sealed box, and forces the air below the stopper plate into the inflation ring along the inside of the moving block, causing the inflation ring to expand and compress the suction cup, making the suction cup more firmly attached to the surface of the inner liner. Then, the stopper plate remains stationary, and a single power source can be used to both evacuate the suction cup and inflate the inflation ring. Subsequently, driven by the hydraulic rod, the suction cup and the inner liner are brought closer together, which can keep the gap tight during welding, avoid the weld from loosening during rotation and causing slight displacement of the inner liner, reduce the power source, and improve the adhesion and durability of the suction cup.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0021] Example 1, please refer to Figures 1-5 The present invention provides a technical solution: a buffer tank inner liner welding device, which is described below.

[0022] The system includes an operating box 1, a moving mechanism 2 located behind the operating box 1, and an inner liner 3 placed on the moving mechanism 2. It also includes: A welding mechanism 4 is provided on one side of the moving mechanism 2, and an auxiliary alignment mechanism 5 is symmetrically provided on the outside of the moving mechanism 2; During operation, the moving mechanism 2 is operated by the control box 1 to bring the inner liner 3 closer together, and the welding mechanism 4 is brought close to the gap connecting the inner liner 3. Then, the auxiliary alignment mechanism 5 fits the outer walls of the two halves of the inner liner 3 together to keep the gap of the inner liner 3 tight. Then, the welding structure welds the gap. The moving mechanism 2 drives the inner liner 3 to rotate in the same direction so that the welding structure can completely weld the inner liner 3.

[0023] Mobile mechanism 2 includes: A base plate 201, with slide rails 202 symmetrically arranged above the base plate 201; The movable seat 203 slides along the slide rail 202 on the base plate 201; The drive wheel 204 is symmetrically arranged above the movable seat 203. The outer side of the drive wheel 204 is in contact with the outer side of the inner liner 3. The rotation of the drive wheel 204 drives the inner liner 3 to rotate coaxially on the movable seat 203, and is then welded together.

[0024] The movable seat 203 moves along the slide rail 202, placing the inner liner 3 above the drive wheel 204. Through the rotation of the drive wheel 204, the inner liner 3 rotates coaxially while approaching each other, ensuring that the part in contact with the welding mechanism 4 always maintains the same distance, thus achieving precise welding of the gaps in the inner liner 3.

[0025] Welding mechanism 4 includes: Base 401, which is located on one side of base plate 201; Fixing plate 402 is installed above base 401; Support arm 403 is installed above the fixed plate 402.

[0026] Welding mechanism 4 also includes: Welding head 404 is installed at the other end of the support arm 403; The protective component 405 is slidably connected to the outside of the support arm 403 and covers the outside of the welding head 404.

[0027] After the inner liner 3 is placed and aligned, the auxiliary alignment mechanism 5 adheres to and adsorbs with the outer wall of the inner liner 3. The support arm 403 drives the welding head 404 to approach the inner liner 3, and then the drive wheel 204 drives the inner liner 3 to rotate, so that the welding head 404 welds the gap of the inner liner 3. At the same time, the protective component 405 covers the welding part to reduce the slag generated during welding from splashing outwards, and blocks the light of welding to prevent impurities generated during welding from adhering to the surface of the inner liner 3.

[0028] The auxiliary alignment mechanism 5 includes a fixed slide 501 and a second slider 502 disposed inside the fixed slide 501, a hydraulic rod 503 mounted on one side of the second slider 502 and an adsorption assembly 504 mounted on the side of the hydraulic rod 503 away from the second slider 502, and a detection assembly 505 slidably connected to the outside of the fixed slide 501.

[0029] After the inner liner 3 is aligned and placed on the drive wheel 204, the mounting base drives the fixed slide 501 close to the surface of the inner liner 3, so that the adsorption component 504 contacts and opens with the surface of the inner liner 3. By sucking the air between the adsorption component 504 and the inner liner 3, it is made to adhere to the surface of the inner liner 3, thereby achieving a gripping force on the surface of the inner liner 3 and keeping the inner liner 3 stable during rotation. During the rotation of the inner liner 3, the adsorption component 504 is driven to rotate along the fixed slide 501, keeping the gap of the inner liner 3 near the welding head 404 in a tight fit. This prevents the inner liner 3 from shifting during the rolling of the inner liner 3 by the drive wheel 204, which would cause the gap to widen, resulting in a larger weld or incomplete welding of the inner liner 3, causing processing errors. The detection component 505 detects the outer diameter of the two halves of the inner liner 3 during the rotation process to determine whether the outer circular surface of the inner liner 3 is still on the same horizontal line after rotation before welding. This further determines whether the inner liner 3 is in a correct alignment state, improving welding accuracy.

[0030] Example 2, please refer to Figures 1-9 The present invention provides a technical solution: based on embodiment 1, the protective component 405 includes: The first slider 4051 is slidably connected to the outside of the support arm 403; The fixed frame 4052 is connected to the outside of the first slider 4051. The position of the fixed frame 4052 is fixed relative to the first slider 4051. During use, it remains stationary so that the extension frame 4053 hangs down naturally. The extension frame 4053 is installed on the side of the fixed frame 4052 near the welding head 404. The extension frame 4053 is a metal louver plate that hangs down naturally to contact the surface of the inner liner 3 during use, blocking the welding position.

[0031] The protective component 405 also includes: Arc-shaped tube 4054 is installed inside the fixed frame 4052. Arc-shaped tube 4054 is rotatably connected inside the fixed frame 4052. When in use, the arc is downward, so that the arc-shaped rod 4055 naturally extends downward, so that the extension frame 4053 unfolds. An arc-shaped rod 4055 is installed inside an arc-shaped tube 4054. One end of the arc-shaped rod 4055 is equipped with an elastic rope 4056, and the other end of the elastic rope 4056 is connected to the inside of the arc-shaped tube 4054. The arc-shaped rod 4055 moves telescopically inside the arc-shaped tube 4054. When the opening of the arc-shaped tube 4054 is downward, it naturally extends and drives the baffle 4057 to block the extension frame 4053, so that the extension frame 4053 moves on the arc-shaped rod 4055. When the arc-shaped tube 4054 rotates 180 degrees and the opening is upward, the arc-shaped rod 4055 retracts and drives the extension frame 4053 to retract. A baffle 4057 is installed at the other end of the arc-shaped rod 4055. The baffle 4057 is used to intercept the extension frame 4053 that moves along the arc-shaped rod 4055, so that the extension frame 4053 can automatically retract to avoid getting caught on the end of the arc-shaped rod 4055.

[0032] When the welding head 404 is aligned with the gap of the inner liner 3 for welding, the arc tube 4054 rotates so that the opening faces downward, causing the arc rod 4055 to fall downward out of the extension frame 4053 and hang down naturally, contacting the surface of the inner liner 3 to form a closed space, enclosing the welding part inside and reducing the splashing of molten slag. After welding is completed, the arc tube 4054 rotates so that the opening faces upward, so that the end of the extension frame 4053 is at a higher position, and then automatically falls back to the vicinity of the fixed frame 4052 due to gravity to complete the winding. This facilitates the automatic adjustment of the welding space enclosed by the extension frame 4053 and the fixed frame 4052, gathers the space around the welding, and facilitates the collection of gas and molten slag generated during welding, reducing the adhesion of molten slag to the surface of the inner liner 3.

[0033] Adsorption component 504 includes: A movable block 5041 is installed at the other end of the hydraulic rod 503, and an air outlet channel 5042 is provided inside the movable block 5041. Branch pipe 5043 passes through the interior of movable block 5041, and one end of branch pipe 5043 is connected to suction cup 5044. The surface of suction cup 5044 has a certain thickness of latex, so that when suction cup 5044 naturally approaches the surface of inner liner 3, it conforms to the curvature of the surface of inner liner 3, so that the inside of suction cup 5044 is sealed, thereby generating negative pressure to adhere to the surface of inner liner 3.

[0034] Adsorption component 504 also includes: The sealing box 5045 is installed above the movable block 5041, and the other end of the branch pipe 5043 is connected to the top of the sealing box 5045. The lifting rod 5046 is installed inside the sealed box 5045. The stopper plate 5047 is installed above the lifting rod 5046. The outside of the stopper plate 5047 is in contact with the inside of the sealing box 5045. The lifting rod 5046 and the stopper plate 5047 are used together to form a piston inside the sealing box 5045. The upward suction of gas creates a negative pressure, and the downward inflation of gas increases the pressure. It can also reverse the gas flow.

[0035] Adsorption component 504 also includes: Connecting pipe 5048 is installed on the outside of movable block 5041 and is connected to air outlet channel 5042. The air ring 5049 is located at the other end of the connecting tube 5048. The outside of the air ring 5049 is in contact with the outside of the suction cup 5044. The air ring 5049 is made of rubber. After inflation, it expands and presses the surface of the suction cup 5044 to make it fit the surface of the inner liner 3 more closely.

[0036] After the hydraulic rod 503 drives the moving block 5041 to a suitable position, the suction cup 5044 is brought close to the surface of the inner liner 3. At this time, the lifting rod 5046 moves downward, causing the suction cup 5044 and the air near the inner liner 3 to be drawn into the interior of the sealing box 5045. The air below the stopper plate 5047 is squeezed into the inflation ring 5049 along the interior of the moving block 5041, causing the inflation ring 5049 to expand and press against the suction cup 5044, making the suction cup 5044 more firmly attached to the surface of the inner liner 3. Then the stopper plate 5047 remains stationary. The suction cup 5044 can be evacuated and the inflation ring 5049 can be inflated using a single power source. Then, driven by the hydraulic rod 503, the suction cup 5044 and the inner liner 3 are brought closer together. During welding, the gap can be kept tight, and the weld seam can be prevented from loosening during rotation, which would cause the inner liner 3 to shift slightly. This reduces the power source and improves the adhesion and durability of the suction cup 5044.

[0037] Detection component 505 includes: Housing 5051, housing 5051 is slidably connected to the outside of fixed slide groove 501; Telescopic rod 5052 is installed inside the housing 5051. The other end of the telescopic rod 5052 is provided with a connecting block 5053. The connecting block 5053 is slidably connected inside the housing 5051. The connecting block 5053 is provided with a contact sensor 5057, which cooperates with the support rod 5055 to determine whether the inner liner 3 is displaced during the movement. Spring 5054 is installed on the other side of connecting block 5053; The probe 5056 is installed at the other end of the spring 5054. A support rod 5055 is provided on the side of the probe 5056 near the spring 5054. The support rod 5055 cooperates with the contact sensor 5057 in the connecting block 5053. Once the inner liner 3 is displaced, the probe 5056 will be squeezed by the inner liner 3, so that the support rod 5055 contacts the surface of the contact sensor 5057. Sensor 5057 is located on the opposite side of probe 5056. Sensor 5057 is an optical sensor that determines whether probe 5056 is on the same horizontal line by emitting and receiving laser light.

[0038] During welding, the inner liner 3 rotates a certain angle within the fixed groove 501 following the second slider 502. Then, the suction cup 5044 releases the inner liner 3, causing the second slider 502 to move the suction cup 5044 downwards again and re-adhere to the inner liner 3. This operation is repeated until the inner liner 3 is completely welded. During the rotation of the inner liner 3, the shell 5051 remains close to the inner liner 3, allowing the telescopic rod 5052 to extend outwards and contact the probe 5056 with the surface of the inner liner 3. The sensors 5057 on the two probes 5056 determine whether two points on the outer surface of the inner liner 3 are on the same horizontal line to determine whether the inner liner 3 has shifted. Also during the rotation of the inner liner 3, the presence of uneven protrusions in the inner liner 3 is determined by whether the probe 5056 is squeezed due to the shift and whether the support rod 5055 contacts the sensor 5057, further determining whether the weld seam of the inner liner 3 is aligned.

[0039] The specific workflow is as follows: During operation, the movable seat 203 is moved along the slide rail 202 by the control box 1, and the inner liner 3 is placed above the drive wheel 204. By rotating the drive wheel 204, the inner liner 3 rotates coaxially while approaching each other, so that the part in contact with the welding mechanism 4 always maintains the same distance. The mounting base moves the fixed slide 501 close to the surface of the inner liner 3, so that the adsorption component 504 contacts and opens with the surface of the inner liner 3. By sucking the air between the adsorption component 504 and the inner liner 3, it is made to adhere to the surface of the inner liner 3, thereby achieving a gripping force on the surface of the inner liner 3 and keeping the inner liner 3 stable during rotation. During the rotation of the inner liner 3, the adsorption component 504 is driven to rotate along the fixed slide 501, keeping the gap of the inner liner 3 near the welding head 404 in a tight fit. This prevents the inner liner 3 from shifting during the rolling process of the drive wheel 204, which would cause the gap to widen, resulting in a larger weld or incomplete welding of the inner liner 3, causing processing errors. The detection component 505 detects the outer diameter of the two halves of the inner liner 3 during the rotation process to determine whether the outer circular surface of the inner liner 3 is still on the same horizontal line after rotation before welding. During welding, the support arm 403 drives the welding head 404 to approach the inner liner 3, and then the drive wheel 204 drives the inner liner 3 to rotate, so that the welding head 404 welds the gap of the inner liner 3. At the same time, the protective component 405 covers the welding part to reduce the slag generated during welding from splashing outwards, and blocks the light of welding to prevent impurities generated during welding from adhering to the surface of the inner liner 3.
