Description

Technical Field

[0001] This utility model relates to the field of adhesive coating equipment technology, and in particular to an adhesive coating equipment for tank body welds. Background Technology

[0002] Existing metal cans are generally cylindrical in shape, typically welded together from a metal can body and a cap. This leaves a weld seam on the can body. To prevent this weld seam from rusting, a common practice is to apply a layer of adhesive to it. This adhesive prevents the weld seam from contacting oxygen in the air, thus preventing oxidation and rust. Adhesive application equipment is usually used for this process.

[0003] Chinese utility model patent CN220277443U discloses a weld seam adhesive application device for can manufacturing. The device includes a vertical plate with an electromagnet mounted on it. A through hole is formed in the vertical plate, and a second bearing is installed within the through hole. A convex rod with an insulating coating is installed within the second bearing. The electromagnet is mounted on the convex rod with the insulating coating. A servo motor is mounted on the vertical plate, and the convex rod with the insulating coating is mounted on the output end of the servo motor. The can's end cap is attracted to the electromagnet. A perforated support plate is mounted on the vertical plate, and a glue tube is mounted on the perforated support plate. The electromagnet fixes the can; rotating the electromagnet causes the can to rotate, while the glue tube simultaneously applies adhesive to the weld seam.

[0004] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: different models of metal cans typically have different diameters, and the aforementioned device can only be adapted to a single model of metal can. This highly specialized design results in a limited range of applicability and insufficient flexibility in use. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a device for applying adhesive to the weld seams of a tank body.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a tank body weld seam adhesive coating equipment, including a frame, a worktable on the frame, an installation groove on the worktable, two sliding seats slidably disposed in the installation groove, a driving component on the worktable for driving the two sliding seats to slide synchronously in opposite directions, two support wheels rotatably disposed on each of the two sliding seats, a column on one side of the worktable, an installation seat on the top of the column, a lifting seat slidably disposed vertically on the installation seat, a rotating shaft rotatably disposed horizontally at the bottom of the lifting seat, two pressure rollers spaced apart on the rotating shaft, a square hole horizontally opened on the lifting seat, a square tube slidably disposed in the square hole, a fixing component for fixing the square tube to the lifting seat disposed in the square tube, an adhesive dispensing pipe disposed on the square tube, and a feeding component for injecting adhesive into the adhesive dispensing pipe disposed on the frame.

[0007] By adopting the above technical solution, a sliding seat, drive assembly, support wheel, lifting seat, pressure wheel, and feeding assembly are set up. The drive assembly drives the two sliding seats to slide synchronously in opposite directions, thereby adjusting the position of the support wheel and providing stable support for cans of different diameters. The sliding lifting seat drives the rotating shaft, pressure wheel, and dispensing tube to descend. The pressure wheel contacts the can to ensure its stability and ensures that the dispensing tube reaches the working height. The sliding square tube drives the dispensing tube to directly above the weld seam. Then, the square tube is fixed by the fixing assembly. Next, the can is rotated, and the feeding assembly injects glue into the dispensing tube. The glue reaches the weld seam through the dispensing tube. This method can perform glue application operations on the weld seams of cans of different diameters, offering high flexibility in use.

[0008] Furthermore, the fixing component includes a rotating shaft horizontally rotatably disposed within a square tube, the axis of the rotating shaft being perpendicular to the length direction of the square tube. A gear is sleeved on the rotating shaft. First slide rails are vertically disposed on both sides of the gear within the square tube. First racks are vertically slidably disposed on the first slide rails via sliders. Both first racks mesh with the gear. Through holes are opened on the body of the square tube corresponding to the first racks. A sliding groove is disposed within the square tube. A second rack is horizontally slidably disposed within the sliding groove, and the second rack meshes with the gear.

[0009] By adopting the above technical solution, a rotating shaft, a gear, a first rack, and a second rack are set up. The sliding second rack drives the gear to rotate, thereby driving the two first racks to slide. When the end of the first rack passes through the through hole and abuts against the wall of the square hole, the position of the first rack and the square tube is fixed.

[0010] Furthermore, a fixing plate is provided at the end of the square tube, and a control tube is provided at the end of the fixing plate away from the square tube. A limit ring is provided at the end of the control tube away from the fixing plate. A sliding block is slidably arranged inside the control tube, and a control post connected to the sliding block is slidably arranged inside the limit ring. A control rod is provided on the side of the sliding block away from the control post. The end of the control rod away from the sliding block passes through the fixing plate and is provided with a connecting block. The connecting block is connected to the second rack. A compression spring is sleeved on the rod body of the control rod located between the fixing plate and the sliding block.

[0011] By adopting the above technical solution, which includes a fixed plate, a limiting ring, a control post, and a control rod, when the horizontal position of the dispensing tube needs to be adjusted, the operator holds the control tube and then presses the control post. This causes the sliding block, control rod, connecting block, and second rack to move. Simultaneously, the compression spring is compressed, causing the gear to rotate and driving the two first racks to slide. The ends of the first racks separate from the wall of the square hole, allowing the operator to pull the control tube to control the sliding of the square tube. Once the dispensing tube is adjusted to the appropriate position, the operator releases the control post. Under the elastic force of the compression spring, the sliding block, control rod, connecting block, and second rack are reset, causing the gear to rotate and driving the two first racks to slide. The ends of the first racks pass through the through hole and abut against the wall of the square hole, thus fixing the position of the square tube.

[0012] Furthermore, the feeding assembly includes a receiving bucket mounted on the frame, and a hydraulic cylinder is vertically mounted on the column directly above the receiving bucket. The piston rod of the hydraulic cylinder points upward and has a piston block mounted thereon. The piston block slides in conjunction with the receiving bucket. A circular hole is provided on the piston block, and a conveying pipe is connected to the circular hole. The other end of the conveying pipe is connected to the dispensing pipe.

[0013] By adopting the above technical solution, a receiving bucket, a hydraulic cylinder, a piston block, a round hole, and a conveying pipe are set up. The receiving bucket contains glue, and the hydraulic cylinder pushes the piston block to descend inside the receiving bucket, so that the glue in the receiving bucket is squeezed into the conveying pipe through the round hole, and then squeezed out from the glue outlet pipe.

[0014] Furthermore, the mounting base has two vertically spaced guide holes, and a guide rod with its lower end connected to the lifting seat is slidably disposed in the guide holes. An electric push rod is vertically disposed on the mounting base, and the piston rod of the electric push rod passes downward through the mounting base and is connected to the lifting seat.

[0015] By adopting the above technical solution, guide holes, guide rods, and electric push rods are set up, and the electric push rods drive the lifting seat to rise and fall.

[0016] Furthermore, the drive assembly includes a bidirectional threaded rod that is horizontally rotatably disposed in the mounting groove. The bidirectional threaded rod is provided with two sections of threads with opposite directions and equal pitch. The two sliding seats are symmetrically distributed on the two sections of threads of the bidirectional threaded rod and are helically connected. One end of the bidirectional threaded rod passes through the worktable and is provided with a handle.

[0017] By adopting the above technical solution, a bidirectional threaded rod and a handle are set. Rotating the handle drives the bidirectional threaded rod to rotate, thereby driving the two sliding seats to slide synchronously towards the center of the receiving groove or synchronously towards the direction away from the center of the receiving groove.

[0018] Furthermore, the bottom of the mounting groove is provided with two second slide rails at intervals, and the sliding seat is slidably connected to the second slide rails.

[0019] Furthermore, a drive motor is horizontally mounted on one of the sliding seats, and the output shaft of the drive motor is connected to one of the support wheels.

[0020] By adopting the above technical solution, a drive motor is horizontally installed on one of the sliding seats, and the drive motor drives one of the support wheels to rotate, thereby causing the tank to rotate.

[0021] In summary, this utility model has the following beneficial effects: This application includes a sliding seat, a drive assembly, a support wheel, a lifting seat, a pressure wheel, and a feeding assembly. The drive assembly drives the two sliding seats to slide synchronously in opposite directions, thereby adjusting the position of the support wheel and providing stable support for cans of different diameters. The sliding lifting seat drives the rotating shaft, pressure wheel, and dispensing tube to descend. The pressure wheel contacts the can to ensure its stability and ensures the dispensing tube reaches the working height. The sliding square tube drives the dispensing tube to directly above the weld seam. The square tube is then fixed by a fixing assembly. The can is then rotated, and simultaneously, the feeding assembly injects glue into the dispensing tube, which reaches the weld seam. This allows for glue application to the weld seams of cans of different diameters, offering high flexibility. Attached Figure Description

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0031] like Figure 1-7As shown in the illustration, this application discloses a tank weld seam adhesive coating device, including a frame 10, sliding seats 20, a drive assembly 30, a lifting seat 50, and a feeding assembly 80. A worktable 11 is mounted on the frame 10, and an installation groove 12 is formed on the worktable 11. Two sliding seats 20 are slidably disposed within the installation groove 12. The drive assembly 30 is mounted on the worktable 11 and is used to drive the two sliding seats 20 to slide synchronously in opposite directions. Two support wheels 21 are rotatably mounted on each of the two sliding seats 20. The axes of the two support wheels 21 on the same sliding seat 20 coincide, and the axes of the support wheels 21 on the two sliding seats 20 are parallel. The drive assembly 30 drives the two sliding seats 20 to slide synchronously in opposite directions, thereby adjusting the position of the support wheels 21 and providing stable support for tanks of different diameters. A column 40 is installed on one side of the workbench 11, and a mounting base 41 is installed on the top of the column 40. A lifting seat 50 is vertically slidably mounted on the mounting base 41, and a rotating shaft 51 is horizontally rotatably mounted at the bottom of the lifting seat 50. The axis of the rotating shaft 51 is parallel to the axis of the support wheel 21. Two pressure rollers 52 are spaced apart on the rotating shaft 51. Sliding the lifting seat 50 drives the rotating shaft 51 and the pressure rollers 52 to descend, and the pressure rollers 52 contact the can to ensure the stability of the can. A square hole 53 is horizontally opened on the lifting seat 50, and a square tube 54 is slidably mounted in the square hole 53. A fixing component 60 is installed in the square tube 54 to fix the square tube 54 to the lifting seat 50. A glue dispensing pipe 70 is installed on the square tube 54. A feeding component 80 is mounted on the frame 10 and is used to inject glue into the glue dispensing pipe 70. When the lifting seat 50 is slid, the glue dispensing pipe 70 descends simultaneously, and the pressure rollers 52 contact the can to ensure that the glue dispensing pipe 70 reaches the working height. The sliding square tube 54 drives the glue dispensing tube 70 to directly above the weld. The square tube 54 is then fixed by the fixing component 60. Next, the can is rotated, and simultaneously, the feeding component 80 injects glue into the glue dispensing tube 70. The glue then reaches the weld through the dispensing tube 70. This method can apply glue to welds of cans with different diameters, offering high flexibility.

[0032] Specifically, the bottom of the mounting groove 12 is provided with two second slide rails 13 at intervals. The sliding seat 20 is slidably connected to the second slide rails 13 to ensure the stability of the sliding seat 20. The drive assembly 30 includes a bidirectional threaded rod 31 horizontally rotatably disposed in the mounting groove 12. The bidirectional threaded rod 31 is provided with two sections of threads with opposite directions and equal pitch. The two sliding seats 20 are symmetrically distributed on the two sections of threads of the bidirectional threaded rod 31 and are helically connected. One end of the bidirectional threaded rod 31 passes through the workbench 11 and is provided with a handle 32. Rotating the handle 32 drives the bidirectional threaded rod 31 to rotate, thereby driving the two sliding seats 20 to slide synchronously toward the center of the receiving groove or synchronously toward the direction away from the center of the receiving groove. A drive motor 22 is horizontally disposed on one of the sliding seats 20. The output shaft of the drive motor 22 is connected to one of the support wheels 21. The drive motor 22 drives one of the support wheels 21 to rotate, thereby driving the tank to rotate.

[0033] During installation, two spaced guide holes 55 are vertically arranged on the mounting base 41. A guide rod 56, whose lower end is connected to the lifting seat 50, is slidably installed in the guide holes 55. The guide rod 56 moves synchronously with the lifting seat 50 to ensure the stability of the lifting seat 50's lifting. An electric push rod 57 is vertically installed on the mounting base 41. The piston rod of the electric push rod 57 passes downward through the mounting base 41 and connects to the lifting seat 50. The electric push rod 57 drives the lifting seat 50 to lift.

[0034] The fixing assembly 60 includes a rotating shaft 61 horizontally rotatably disposed within a square tube 54. The axis of the rotating shaft 61 is perpendicular to the length direction of the square tube 54. A gear 611 is fitted onto the rotating shaft 61. First slide rails 62 are vertically arranged on both sides of the gear 611 within the square tube 54. First racks 621 are vertically slidably disposed on the first slide rails 62 via sliders. Both first racks 621 mesh with the gear 611. When the gear 611 rotates, it drives the two first racks 621 to slide synchronously in opposite directions. A through hole 63 is provided on the body of the square tube 54 corresponding to the first rack 621, allowing the end of the first rack 621 to pass through and contact the inner wall of the square hole 53. A groove 64 is provided inside the square tube 54. A second rack 641 is horizontally slidably arranged in the groove 64. The second rack 641 meshes with the gear 611. Sliding the second rack 641 drives the gear 611 to rotate, thereby driving the two first racks 621 to slide. When the end of the first rack 621 passes through the through hole 63 and abuts against the wall of the square hole 53, the positions of the first rack 621 and the square tube 54 are fixed.

[0035] In the specific configuration, a fixing plate 65 is provided at the end of the square tube 54. A control tube 66 is provided at the end of the fixing plate 65 away from the square tube 54. A limit ring 661 is provided at the end of the control tube 66 away from the fixing plate 65. A sliding block 662 is slidably provided inside the control tube 66. A control post 663 connected to the sliding block 662 is slidably provided inside the limit ring 661. A control rod 664 is provided on the side of the sliding block 662 away from the control post 663. The end of the control rod 664 away from the sliding block 662 passes through the fixing plate 65 and is provided with a connecting block 665, so that the sliding block 662, the control post 663, the control rod 664, and the connecting block 665 move synchronously. The connecting block 665 is connected to the second rack 641. The control rod 664 is located between the fixed plate 65 and the sliding block 662 and is fitted with a compression spring 666. One end of the compression spring 666 is connected to the fixed plate 65 and the other end is connected to the sliding block 662. In the initial state, the compression spring 666 provides a thrust to the sliding block 662 to ensure the stability of the positions of the sliding block 662, the connecting block 665, the control rod 664, the second rack 641, and the gear 611, thereby ensuring that the end of the first rack 621 is stably in contact with the wall of the square hole 53, so that the positions of the first rack 621 and the square tube 54 are fixed. When the horizontal position of the dispensing tube 70 needs to be adjusted, the operator holds the control tube 66 and then presses the control column 663, which moves the sliding block 662, control rod 664, connecting block 665, and second rack 641. At the same time, the compression spring 666 is compressed, causing the gear 611 to rotate and drive the two first racks 621 to slide. The ends of the first racks 621 separate from the wall of the square hole 53, and the operator can then pull the control tube 66 to control the sliding of the square tube 54. After the dispensing tube 70 is adjusted to the appropriate position, the operator releases the control column 663. Under the elastic force, the compression spring 666 pushes the sliding block 662, control rod 664, connecting block 665, and second rack 641 back to their original positions, causing the gear 611 to rotate and drive the two first racks 621 to slide. The ends of the first racks 621 pass through the through hole 63 and abut against the wall of the square hole 53, thereby fixing the position of the square tube 54.

[0036] The feeding assembly 80 includes a receiving tank 81 mounted on the frame 10. A hydraulic cylinder 82 is vertically mounted on the column 40 directly above the receiving tank 81. The piston rod of the hydraulic cylinder 82 points upward and has a piston block 83 mounted on it. The piston block 83 slides in contact with the receiving tank 81. Several rubber rings are fitted on the piston block 83, with the outer diameter of the rubber rings matching the inner diameter of the receiving tank 81, ensuring a sealed fit between the piston block 83 and the receiving tank 81 when the piston block 83 is inside the receiving tank 81. A circular hole is formed on the piston block 83, through which a conveying pipe 84 is connected. The other end of the conveying pipe 84 is connected to a glue outlet pipe 70. The receiving tank 81 contains glue. The hydraulic cylinder 82 pushes the piston block 83 downward within the receiving tank 81, causing the glue in the receiving tank 81 to be squeezed through the circular hole into the conveying pipe 84, and then extruded from the glue outlet pipe 70. After the glue in the container 81 is used up, the hydraulic cylinder 82 drives the piston block 83 to rise, causing the piston block 83 to leave the container 81. Glue is then added back into the container 81, and the hydraulic cylinder 82 pushes the piston block 83 down into the container 81. Next, an air venting operation is required. A collection bucket is placed below the glue outlet pipe 70, and the hydraulic cylinder 82 pushes the piston block 83 down, expelling the air below it. During this air venting process, some glue is also expelled, which is collected in the collection bucket for later use. The air venting operation continues until glue can be consistently squeezed out of the glue outlet pipe 70.

[0037] The operating principle of the tank body weld seam adhesive coating equipment in this embodiment is as follows:

[0038] The operator first turns handle 32 to rotate the bidirectional threaded rod 31, which drives the two sliding seats 20 to slide and adjusts the position of the support wheels 21. Then, the can is placed on the four support wheels 21. Next, the electric push rod 57 is activated to drive the lifting seat 50 to descend, which in turn drives the rotating shaft 51, pressure roller 52, and dispensing hose 70 to descend. The pressure roller 52 contacts the can to ensure its stability, while the dispensing hose 70 reaches the working height.

[0039] Next, the worker holds the control tube 66 and presses the control column 663, causing the sliding block 662, control rod 664, connecting block 665, and second rack 641 to move, which in turn drives the gear 611 to rotate, thereby causing the two first racks 621 to slide, separating the ends of the first racks 621 from the wall of the square hole 53. At this point, the worker can pull the control tube 66 to control the sliding of the square tube 54, adjusting the glue dispensing tube 70 to the appropriate position. The worker then releases the control column 663, and the compressed spring 666, under its elastic force, pushes the sliding block 662, control rod 664, connecting block 665, and second rack 641 back to their original positions, causing the gear 611 to rotate, driving the two first racks 621 to slide. The ends of the first racks 621 pass through the through hole 63 and abut against the wall of the square hole 53, thereby fixing the position of the square tube 54.

[0040] Finally, the drive motor 22 and hydraulic cylinder 82 are started. The drive motor 22 drives one of the support wheels 21 to rotate, thereby causing the can to rotate. This pushes the piston block 83 down inside the receiving tank 81, causing the glue in the receiving tank 81 to be squeezed into the delivery pipe 84 through the round hole, and then squeezed out from the glue outlet pipe 70 and applied to the weld.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
