Description

Technical Field

[0001] This application relates to the technical field of tank manufacturing, and in particular to a tank capping production line. Background Technology

[0002] Currently, automated production technology for can packaging is relatively mature and widely used in industries such as food, beverage, and chemicals.

[0003] A can capping production line typically includes a conveyor line and a capping machine. The conveyor line transports the can and the cap, and the capping machine picks up the cap and places it on the can before capping it. However, during the transport of the can and the cap, displacement can easily cause positional deviations, resulting in the can being capped incorrectly or even the cap falling off before being properly capped, thus reducing the quality of can capping. Summary of the Invention

[0004] To improve the quality of tank capping, this application provides a tank capping production line.

[0005] This application provides a tank capping production line, which adopts the following technical solution:

[0006] A can capping production line includes a machine body, a twin-screw conveyor and a conveyor belt mounted on the machine body for conveying cans and caps, and a capping device mounted on the machine body for capping, the capping device comprising:

[0007] The positioning plate is rotatably mounted on the machine body, and the twin-screw conveyor line pushes the tank to be placed on the upper surface of the positioning plate.

[0008] A positioning component is disposed on the lower surface of the positioning disk and is used to position the tank located on the upper surface of the positioning disk by generating magnetic attraction.

[0009] A driving component, used to drive the positioning disc to rotate and to adjust the angle of the tank;

[0010] Clamping assembly, used to clamp the tank and move it to adjust the position of the tank;

[0011] The cap-grabbing mechanism is used to grab the cap and then transport it.

[0012] The detection component is installed on the machine body and is used to detect the positions of both the gripped lid and the can located on the positioning plate. The driving component and the clamping component adjust the angle and position of the can to match the angle and position of the lid according to the detection data. Finally, the gripping and capping mechanism is activated to complete the capping.

[0013] By adopting the above technical solution, the twin-screw conveyor line pushes the tank to move, and the conveyor belt transports the lid to move. The tank is pushed onto the positioning plate, the twin-screw conveyor line stops running, the positioning component positions the tank with magnetic attraction, the capping mechanism grasps the lid for transport, and the detection component is used to detect the position of both the grasped lid and the tank. Based on the detection data, the drive component drives the positioning plate to rotate to adjust the angle of the tank. At the same time, the clamping component is used to clamp the tank to move and adjust the horizontal position of the tank, thereby realizing that the angle and position of the tank adapt to the angle and position of the lid. After the first adjustment is completed, the detection component continues to detect the position of the tank. If the position of the tank does not meet the requirements, the adjustment continues until the requirements are met and then the adjustment stops. After all the adjustments are completed, the clamping component moves away from the tank, and the positioning plate continues to magnetically attract and position the tank.

[0014] The capping mechanism is activated to perform capping processing, thereby completing the capping of the can. Finally, the twin-screw conveyor line is activated to push the capped can forward to move away from the positioning plate, and then the next can continues to move forward to the positioning plate. At the same time, the capping mechanism continues to grab the cap for inspection and transportation, and then repeats the process, so that the capping can be completed continuously and automatically.

[0015] The can is moved by a twin-screw conveyor, the capping mechanism grips the cap, the detection component detects the position of the can and the cap, the positioning plate is used to position the can, the drive component adjusts the angle of the can, and the clamping component moves the can horizontally against the magnetic attraction of the positioning plate. This greatly improves the accuracy of the capping position and thus improves the capping quality. Moreover, the clamping component moves away from the can before capping, reducing the adverse effects of the clamping component on the capping and further improving the capping quality.

[0016] In this application, the positioning component is located on the lower surface of the positioning disk and uses magnetic attraction to position the tank. There is no need to set up a clamping structure on the positioning disk, thereby reducing the interference generated when the twin-screw conveyor pushes the tank to move. The driving component and the clamping component operate independently of each other, making the structure simple and stable. At the same time, there is no magnetic attraction after the tank is moved out of the positioning disk, which facilitates the movement of the tank. The structure operates stably and saves time, thus improving the capping efficiency of the tank.

[0017] Simultaneously, the tank is moved by a twin-screw conveyor. Because the twin-screw conveyor is curved, its minimum diameter is smaller than the outer diameter of the tank to move it. Therefore, the maximum diameter of the twin-screw conveyor can be larger than the diameter of the tank. Since there is a gap between the twin-screw conveyor and the tank, it is easy to adjust the tank. Thus, the tank can be adjusted while being driven to move.

[0018] Optionally, an annular positioning groove is coaxially formed on the lower surface of the positioning disk, and the positioning assembly includes:

[0019] The magnetic ring is snapped onto the positioning groove and used to adsorb and position the tank.

[0020] The positioning screw passes through the magnet ring and is threaded into the positioning groove for positioning.

[0021] By adopting the above technical solution, the magnetic ring can achieve adsorption and positioning of the can. At the same time, the magnetic ring is circular, which makes the adsorption force on the can moved to the positioning plate more uniform and facilitates the subsequent pushing of the can out of the positioning plate. It also reduces the probability of wear between the can and the positioning plate in some areas due to uneven adsorption force. Furthermore, the circular magnetic ring increases the range of adsorption force, and the overall structure also improves the adsorption effect. Therefore, it can improve the stability of the can when rotating and further improve the capping quality of the can.

[0022] Optionally, mounting plates are provided on both sides of the machine body in the tank conveying direction, and the clamping assembly includes:

[0023] The first and second movable parts are respectively mounted on two mounting plates with the piston rods facing each other.

[0024] Two clamping plates are provided on the piston rods of the first and second moving parts, and the side walls on opposite sides are provided with arc-shaped clamping surfaces that fit the tank body.

[0025] By adopting the above technical solution, based on the test data, the first and second moving parts are simultaneously activated to drive the two clamping plates to move. The two clamping surfaces on the two clamping plates clamp the tank body, enabling the tank body to be positioned along the direction of movement of the tank body, and also to be positioned along the direction perpendicular to the direction of movement of the tank body. Thus, the two clamping plates with clamping surfaces can be used to position the tank body in two mutually perpendicular directions. Moreover, after the position of the tank body is adjusted, the detection component can continue to perform detection until the requirements are met. By using different moving distances of the two clamping plates, the tank body positions with different requirements can be positioned, thereby further improving the capping quality of the tank body.

[0026] Optionally, the two clamping plates are provided with a pressing surface and a positioning surface on the side wall near the tank body and above the clamping surface. The pressing surface is located above the positioning surface and is inclined. After the two clamping plates clamp and position the tank body, they move away from the tank body, and during this process, the pressing surface and the positioning surface do not contact the tank body. The gripping and capping mechanism performs capping processing. The two clamping plates move back, so that the two positioning surfaces clamp the cap and the two clamping surfaces clamp the tank body for positioning. The gripping and capping mechanism moves upward and disengages from the cap body. When the cap body is not pressed into place, the pressing surface generates an inclined downward squeezing force on the cap and presses the cap body into place.

[0027] By adopting the above technical solution, if there is still an adsorption force when the gripping capping mechanism moves upward and separates from the cap, the capped cap is easy to separate from the can under the action of the adsorption force. Alternatively, the gripping capping mechanism may also cause the cap to not be properly capped due to other reasons, thereby reducing the capping quality of the can.

[0028] After the capping mechanism is activated and presses the cap onto the tank, it maintains its original position. The two clamping plates approach the tank, causing the two positioning surfaces to press against the cap for positioning. If the tank shifts during the capping process, the clamping surfaces further position the tank. The squeezing force of the capping mechanism at this time can also press the cap into place if it is not properly capped. Then, the capping mechanism moves upward and disengages from the cap. Because the two positioning surfaces provide positioning, the probability of the cap moving upward and causing the cap to shift upward is reduced. Furthermore, when the two clamping plates move back, if the cap is not properly capped (i.e., the cap is at a higher position), the two squeezing surfaces can press the cap downward to ensure it is properly capped, further reducing the probability of improper capping and improving the capping quality of the tank.

[0029] Optionally, both mounting plates are vertically slidably mounted on the machine body via sliding rods. The machine body is provided with an adjustment assembly connected to the two sliding rods, the adjustment assembly comprising:

[0030] The adjustment plate is located at the bottom of the two sliding rods;

[0031] The adjusting screw is rotatably mounted on the machine body and threadedly connected to the adjusting plate, and is used to vertically adjust the position of the two mounting plates.

[0032] By adopting the above technical solution, the adjustment screw rotates to drive the adjustment plate to move, and the movement of the adjustment plate drives the two mounting plates to move simultaneously, thereby adjusting the position of the clamping assembly. Therefore, it is possible to clamp and adjust the position of tanks of different heights.

[0033] Optionally, the gripping and capping mechanism includes:

[0034] The gripping disc is rotated and mounted on the machine body;

[0035] Rotating component, used to drive the gripping disk to rotate;

[0036] Multiple gripping components are arranged in a circular array around the axis of rotation of the gripping disk and move vertically to adsorb, grip, and position the cover. The detection component forms a detection station at the position of the cover. The gripping component grips the cover, rotates to the detection station for detection, and then rotates to the tank body for capping.

[0037] By adopting the above technical solution, the rotating component drives the rotating disk and multiple gripping components to rotate simultaneously. When the gripping components reach the conveyor belt, they move down to grip the cover. Then, the gripping components and the cover move to the inspection station to inspect the position of the cover. At the same time, the inspection component also inspects the position of the can that has moved to the positioning plate. Then, the driving component and clamping components start to adjust the angle and position of the can to match the angle and position of the cover. Next, the gripping components and the cover move to the can, and the gripping components move down to drive the cover to press onto the can, thus completing the can capping. Multiple stations simultaneously realize the gripping, inspection and capping of the cover. Therefore, the three processes are carried out at the same time, which greatly reduces the can capping time, improves the can capping efficiency, and allows enough time to adjust the position and angle of the can, thus improving the capping quality of the can.

[0038] Optionally, the grasping component includes:

[0039] The lifting component is mounted on the gripping disc with the piston rod positioned vertically downwards.

[0040] The lifting block is mounted on the piston rod of the lifting component.

[0041] The suction cup is mounted on the lifting block and is used to suction and position the cover.

[0042] By adopting the above technical solution, the lifting component drives the lifting block to move vertically. The lifting block moves down, driving the suction cup to move down and adsorb the cover. Then, the lifting block moves up, driving the suction cup and the cover to move together. The lifting block moves down, driving the cover to press onto the can. Then, the suction cup releases its adsorption force on the cover. The lifting block moves up, driving the suction cup to move up, thus completing the capping of the can.

[0043] Optionally, the machine body is provided with a pressure-rebalancing assembly, the pressure-rebalancing assembly comprising:

[0044] The pressure seat is vertically slidably mounted on the machine body;

[0045] The spring is mounted on the machine body and connected to the pressure base.

[0046] The repress roller is rotatably mounted on the repress base and located outside the positioning plate. Under the action of the spring, it represses the cover after it has been pressed.

[0047] By adopting the above technical solution, after the twin-screw conveyor drives the capping, the tank continues to move forward. The tank moves to the outside of the positioning plate and then to the re-pressing roller. Under the action of the spring, the re-pressing roller continues to re-press the cap, thereby further reducing the probability of the cap not being properly pressed and improving the capping quality of the tank.

[0048] Optionally, multiple repressurization components are provided at intervals along the tank's moving direction, and the height of the repressurization components gradually decreases along the tank's moving direction to gradually increase the compressive force on the cover.

[0049] By adopting the above technical solution, the cap body is gradually squeezed through multiple pressure-repressing components, thereby improving the pressure-repressing effect of the pressure-repressing components and improving the capping quality of the tank body.

[0050] Optionally, the body is equipped with a buzzer sensor, and the pressure seat is equipped with a sensing rod. When the cover is not pressed into place, the cover pushes the pressure seat and the sensing rod upward, so that the sensing rod abuts against the buzzer sensor and causes the buzzer sensor to sound an alarm.

[0051] By adopting the above technical solution, when the cover is not properly pressed, the height of the cover increases. As a result, the cover pushes the re-pressing roller, the re-pressing seat, and the sensing rod to move upward simultaneously. If the re-pressing roller is pressed under the action of the spring and the cover is pressed in place, the sensing rod will not contact the buzzer sensor. Otherwise, the sensing rod will abut against the buzzer sensor and sound an alarm, thereby reminding the staff to inspect the equipment and remove defective products, thus further improving the capping quality of the can.

[0052] In summary, this application includes at least one of the following beneficial technical effects:

[0053] 1. The can is moved by a twin-screw conveyor, the capping mechanism grips the cap, the detection component detects the position of the can and the cap, the positioning plate is used to position the can, the drive component drives and adjusts the angle of the can, and the clamping component starts to push the can to move horizontally against the magnetic attraction of the positioning plate, which can greatly improve the accuracy of the position during capping, thereby improving the capping quality of the can. Moreover, the clamping component moves away from the can before capping, reducing the adverse effects of the clamping component on the capping, thereby further improving the capping quality of the can.

[0054] 2. The positioning component is set on the lower surface of the positioning plate and uses magnetic attraction to position the tank. There is no need to set a clamping structure on the positioning plate, which reduces the interference caused by the twin screw conveyor pushing the tank to move. The driving component and the clamping component operate independently, making the structure simple and stable. At the same time, there is no magnetic attraction after the tank is removed from the positioning plate, which facilitates the movement of the tank. The structure operates stably and saves time, thus improving the capping efficiency of the tank. Attached Figure Description

[0062] The following provides a further detailed description of this application.

[0063] This application discloses a tank capping production line.

[0064] Reference Figure 1 and Figure 2 The can capping production line includes a machine body 1, a twin-screw conveyor line 11 and a conveyor belt 12 mounted on the machine body 1 for conveying cans and caps, and a capping device 2 mounted on the machine body 1 for capping.

[0065] The twin-screw conveyor line 11 and the conveyor belt 12 are arranged at intervals and their conveying directions are parallel to each other. The twin-screw conveyor line 11 is used to push the tank body to move, and the conveyor belt 12 is used to convey the lid body and one end extends to the middle position of the twin-screw conveyor line 11. A baffle plate 13 extending above one end of the conveyor belt 12 is fixedly installed on the machine body 1. The baffle plate 13 has an arc-shaped baffle surface 14. The baffle surface 14 is used to fit against the lid body for positioning. The conveyor belt 12 is used to transport the lid body to move and abuts against the baffle surface 14 for positioning. The twin-screw conveyor line 11 and the conveyor belt 12 are both existing technologies and will not be described in detail here.

[0066] Reference Figures 2-4 The capping device 2 includes a positioning plate 21, a driving component 22, and a positioning assembly 3. Two mounting holes 15 are provided on the machine body 1 and located within the twin-screw conveyor line 11 along the direction of tank movement, and the two mounting holes 15 correspond to the baffle plate 13. Two driving components 22 are provided and are motors. The two driving components 22 are fixedly installed on the lower surface of the machine body 1, and the output shafts of the two driving components 22 extend coaxially into the two mounting holes 15. Two positioning plates 21 are provided and are provided one-to-one with the two driving components 22. The two positioning plates 21 are coaxially fixedly installed on the output shafts of the two driving components 22, and the upper surfaces of the positioning plates 21 and the machine body 1 are flush.

[0067] The positioning disk 21 is coaxially arranged with the mounting hole 15 and has a rotational clearance between them. The lower surface of the positioning disk 21 has an annular positioning groove 23 starting coaxially. The positioning component 3 includes a magnetic ring 31 and a positioning screw 32. The magnetic ring 31 is snapped onto the positioning groove 23 and is used to generate an adsorption force on the can that is moved onto the positioning disk 21. Multiple positioning screws 32 are arranged in a circumferential array around the axis of the positioning disk 21. The positioning screws 32 pass through the lower surface of the magnetic ring 31 and are threaded to the bottom of the positioning groove 23, thereby positioning the magnetic ring 31.

[0068] The twin-screw conveyor 11 pushes the two tanks to move simultaneously, so that the two tanks are moved onto the two positioning disks 21. The two magnetic rings 31 respectively generate an adsorption force on the two tanks and are positioned on the two positioning disks 21. The driving component 22 drives the positioning disks 21 to rotate, and the rotation of the positioning disks 21 is used to adjust the angle of the tanks.

[0069] Reference Figures 2-3The capping device 2 also includes a clamping assembly 4, a capping gripping mechanism 7, and a detection assembly 6. Mounting plates 16 are vertically slidably mounted on the upper surface of the machine body 1, on both sides of the twin screw conveyor line 11, and corresponding to the two mounting holes 15, via sliding rods 53. The mounting plates 16 are horizontal and located above the twin screw conveyor line 11. The sliding rods 53 are fixedly mounted on the lower surface of the mounting plates 16 and vertically slid through the upper surface of the machine body 1. The bottom of the sliding rods 53 extends to the bottom of the machine body 1.

[0070] The body 1 is provided with an adjustment assembly 5 connected to two sliding rods 53. The adjustment assembly 5 includes an adjustment plate 51 and an adjustment screw 52. The adjustment plate 51 is fixedly installed at the bottom of the two sliding rods 53 and is in a horizontal state. The adjustment screw 52 is threadedly connected to the adjustment plate 51 and rotatably connected to the lower surface of the body 1. The rotation of the adjustment screw 52 drives the adjustment plate 51, the sliding rods 53 and the two mounting plates 16 to move vertically.

[0071] The clamping assembly 4 is mounted on two mounting plates 16 and is used to clamp the can and move it to adjust the position of the can. The gripping and capping mechanism 7 is used to attach the can to the upper surface of the cap by suction force and then transport it. The detection assembly 6 is mounted on the machine body 1 and is used to detect the position of both the gripped cap and the can located on the positioning plate 21. The drive component 22 and the clamping assembly 4 adjust the angle and position of the can to match the cap according to the detection structure. Finally, the gripping and capping mechanism 7 is started to complete the capping.

[0072] Reference Figure 2 , Figure 3 The clamping assembly 4 includes a first moving member 41 and a second moving member 42, and two clamping plates 43. Both the first moving member 41 and the second moving member 42 are electric actuators and are respectively fixedly mounted on the upper surfaces of the two mounting plates 16. The piston rods of the first moving member 41 and the second moving member 42 are arranged opposite each other and extend between the two mounting plates 16. The two clamping plates 43 are fixedly mounted on the piston rods of the first moving member 41 and the second moving member 42 and are arranged opposite each other. The first moving member 41 and the second moving member 42 are used to drive the two clamping plates 43 to move closer or further apart, and the moving direction of the two clamping plates 43 is perpendicular to the moving direction of the tank. A control box is provided on the machine body 1 to control the start and stop of the drive member 22, the first moving member 41, and the second moving member 42. The detection assembly 6 detects data and transmits it to the control box, which then controls the start and stop of the drive member 22, the first moving member 41, and the second moving member 42 based on the detection data.

[0073] Reference Figure 3 , Figure 5The two clamping plates 43 have arc-shaped clamping grooves 49 on their opposite sidewalls. A protruding clamping block 44 is coaxially positioned at the bottom of each clamping groove 49. An arc-shaped clamping surface 45, conforming to the tank body, is formed on the opposite sidewall of each clamping block 44. A pressing block 46 is coaxially positioned at the top of each clamping groove 49. A pressing surface 47 and a positioning surface 48, connected to each other, are formed on the opposite sidewall of each pressing block 46. The pressing surface 47 is inclined and arc-shaped, with its bottom diameter smaller than its top diameter. The positioning surface 48 is located below the pressing surface 47 and is annular, with its diameter matching the bottom diameter of the pressing surface 47.

[0074] Reference Figure 2 , Figure 3 , Figure 5 When the two clamping plates 43 approach each other and the two clamping surfaces 45 come into contact with the can, they will push the can to move, so that the can fit with the two clamping surfaces 45. At the same time, the two clamping plates 43 move the same or different distances as needed, so that the can moves along the two conveying directions perpendicular to and parallel to the can to overcome the adsorption force of the magnetic ring 31 on the can. In this way, the position of the can is adjusted from two mutually perpendicular directions according to the detection structure of the detection component 6, so that the position and angle of the can are adapted to the position and angle of the cover.

[0075] After adjustment, the two clamping plates 43 move away from the tank body. At this time, the capping mechanism 7 starts to move the cap body down for capping. Then, the capping mechanism 7 maintains the squeezing state on the cap body, and the two clamping plates 43 move back, so that the two positioning surfaces 48 press against the outer wall of the cap body for positioning, and the two clamping surfaces 45 continue to press against the outer wall of the tank body for positioning.

[0076] When the can body shifts during the capping process, the two clamping surfaces 45 can retract to allow the can body to return to the correct position. Since the capping mechanism 7 maintains downward pressure on the cap, it can continue to cap the can body into place. Alternatively, if the capping mechanism 7 fails to cap the can body into place, i.e., the cap body is higher than the required position, the pressing surfaces 47 can press against the upper surface of the cap body during the retraction of the two clamping plates 43. This pushes the cap body into place, causing the two positioning surfaces 48 to press against the cap body for positioning. At the same time, the two positioning surfaces 48 position the cap body. Then, the capping mechanism 7 moves upward and disengages from the cap body, thus reducing the probability of the cap body moving upward when the capping mechanism 7 moves upward, thereby further improving the capping quality and efficiency of the can body.

[0077] Reference Figure 2 , Figure 4A fixing plate 17 is fixedly installed on the machine body 1 between the twin-screw conveyor line 11 and the conveyor belt 12. A fixing plate 18 extending above the twin-screw conveyor line 11 is fixedly installed on the machine body 1 on both sides of the two mounting holes 15. The detection component 6 is provided with two capping detection devices, each corresponding to a cap. The detection component 6 includes a position detector 61 and a position detector 62. The position detector 61 is fixedly installed on the upper surface of the fixing plate 17, while the position detector 62 is fixedly installed on one of the fixing plates 18. The two position detectors 61 on the fixing plate 17 are used to detect the positions of the two caps gripped by the capping mechanism 7, while the two position detectors 62 on the two fixing plates 18 are used to detect the positions of the cans located on the two positioning discs 21.

[0078] The gripping and capping mechanism 7 includes a gripping disk 71, a rotating component 72, and multiple gripping assemblies 73. The gripping disk 71 is rotatably mounted on the machine body 1, and the gripping disk 71 is in a horizontal state with its rotation axis in a vertical state. The rotating component 72 is fixedly mounted on the machine body 1 and is used to drive the rotating disk to rotate. The rotating component 72 can be a slip ring, which is existing technology and will not be described in detail here.

[0079] The number of gripping components 73 is four. The four gripping components 73 are arranged in a circular array around the axis of the gripping disk 71. Two opposing gripping components 73 are located above the conveyor belt 12 and the two mounting holes 15. One of the gripping components 73 is located above the fixed plate 17. The two position detectors 61 on the fixed plate 17 form a detection station, which is the detection position of the cover. The gripping component 73 moves vertically to adsorb, grip, and position the cover. After the gripping component 73 moves down to grip two covers, it moves up. The gripping disk 71 rotates to drive the gripping component 73 and the two covers to the two position detectors 61. The two position detectors 61 are used to detect the angle and position of the two covers.

[0080] Reference Figures 2-4 Simultaneously, the twin-screw conveyor 11 pushes the two cans onto the two positioning discs 21 for adsorption and positioning. The two position detectors 62 are used to detect the angle and position of the two cans. Then, the drive unit 22 and the two clamping plates 43 move to adjust the position of the two cans so that the position and angle of the two cans match the position and angle of the two lids. The gripping disc 71 drives the gripping assembly 73 to move to the two cans. The gripping assembly 73 moves down to press the two lids onto the two cans. The gripping assembly 73 moves up, and the lids located on the three gripping assemblies 73 are gripped, detected and pressed on at the same time.

[0081] The gripping assembly 73 includes a lifting component 74, a lifting block 75, and suction cups 76. The lifting component 74 is a lifting cylinder or an electric actuator. The lifting component 74 is fixedly installed on the gripping disk 71 with its piston rod vertically downward. The lifting block 75 is fixedly installed on the piston rod of the lifting component 74 and is in a horizontal state. Two suction cups 76 are spaced apart and fixedly installed on the lower surface of the lifting block 75. The two suction cups 76 can suck air to adsorb and transport the two covers, or the two suction cups 76 can release air to release the adsorption of the covers.

[0082] Reference Figure 2 , Figure 6 The machine body 1 is fixedly installed with a mounting base 19 extending above the twin screw conveyor line 11 and located on one side of the two positioning plates 21. When the twin screw conveyor line 11 is started, it pushes the two capped cans to move below the mounting base 19. Multiple re-pressing components 8 are arranged at intervals along the can conveying direction on the mounting base 19. The re-pressing components 8 are used to re-press the caps, and the height of the multiple re-pressing components 8 gradually decreases along the can conveying direction and is used to gradually increase the pressing force on the caps.

[0083] The repressurization assembly 8 includes a repressurization seat 81, a spring 82, and a repressurization roller 83. The repressurization seat 81 is vertically slidably mounted on the mounting base 19. A mounting block 84 is fixedly mounted on the machine body 1 above the repressurization seat 81. A buzzer sensor 85 is fixedly mounted on the machine body 1 above the mounting block 84. A sensing rod 86 is vertically slidably mounted on the mounting block 84 on the upper surface of the repressurization seat 81. The spring 82 is sleeved on the sensing rod 86 and its two ends are fixedly connected to the opposite side walls of the mounting block 84 and the repressurization seat 81. The spring 82 pushes the repressurization seat 81 to maintain a downward trend. The repressurization roller 83 is rotatably mounted on the repressurization seat 81 and is in a horizontal state. At the same time, the axis of the repressurization roller 83 is perpendicular to the direction of movement of the tank.

[0084] The tank and cover are moved below the repressing roller 83. Under the action of elasticity, the repressing roller 83 presses against the cover for a second compression. The cover will push the repressing roller 83, the repressing seat 81 and the sensing rod 86 upward. When the cover is not in place during the repressing process of the repressing roller 83, that is, the cover is too high, the cover will push the sensing rod 86 upward to abut against the buzzer sensor 85. The buzzer sensor 85 will sound an alarm, thus reminding the staff to pay attention to the equipment operation and reject unqualified tanks.

[0085] The working principle of this application embodiment is as follows:

[0086] The twin-screw conveyor 11 pushes the two tanks to move simultaneously, so that the two tanks are positioned on the two positioning disks 21. The twin-screw conveyor 11 stops running. The two position detectors 62 are used to detect the angle and position of the two tanks. At the same time, the two suction cups 76 move down to grab the two lids and then move up. The gripping disk 71 rotates to drive the two lids to the two position detectors 61 for detection. The driving component 22 and the two clamping plates 43 move simultaneously to adjust the angle and position of the tanks to match the angle and position of the lids. The two clamping plates 43 move away from the tanks at the same time.

[0087] The gripping disc 71 rotates, driving the two suction cups 76 and the two covers to the two cans. The two suction cups 76 move down, driving the two covers down, and placing the two covers on the two cans. The two suction cups 76 maintain the pressure on the covers. The two clamping plates 43 move back and clamp the cans and covers. The two suction cups 76 release the suction force and move up. The gripping disc 71 rotates and continues, thus completing the capping of the cans.

[0088] The twin-screw conveyor 11 starts and pushes the two tanks to move. After the two tanks are moved to the outside of the positioning plate 21, they are successively pressed by multiple pressure rollers 83, so that the lid can be squeezed again. If the lid is not properly sealed after squeezing, the pressure rollers 83 move upward, so that the sensing rod 86 abuts against the buzzer sensor 85 to sound an alarm. This allows the staff to pay attention to the operation of the equipment in time and remove unqualified tanks, thereby improving the sealing quality and efficiency of the tanks.

[0089] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
