Description

Technical Field

[0001] The present application relates to the technical field of can production, and in particular to a can capping production line. Background Art

[0002] At present, the automated production technology of can packaging has become relatively mature and is widely used in food, beverage, chemical and other industries.

[0003] The can capping production line usually includes a conveyor line and a capping machine. The conveyor line is used to convey the can body and the cap body. The capping machine then grabs the cap body and places it on the can body for capping to complete the can capping process. However, the position of the cap body and the can body may deviate due to displacement during the conveying process, resulting in the incorrect position of the can body after capping, or even the cap body may fall off due to failure to be capped in place, thereby reducing the quality of the can body capping. Summary of the invention

[0004] In order to improve the quality of can capping, the present application provides a can capping production line.

[0005] The present application provides a can capping production line, which adopts the following technical solutions: A can body capping production line comprises a machine body, a twin-screw conveying line and a conveying belt arranged on the machine body and used for conveying can bodies and caps, and a capping device arranged on the machine body and used for capping, wherein the capping device comprises: The positioning plate is rotatably arranged on the machine body, and the twin-screw conveyor line pushes the can body to move to the upper surface of the positioning plate for placement; A positioning assembly is disposed on the lower surface of the positioning plate and is used to generate a magnetic attraction force to position the tank body located on the upper surface of the positioning plate; A driving member, used for driving the positioning plate to rotate and for adjusting the angle of the tank body; A clamping assembly, used to clamp the tank body and move it to adjust the position of the tank body; The grabbing and capping mechanism is used to grab the cap body and then transport it; The detection component is arranged on the machine body and is used to detect the positions of the captured cover body and the can body on the positioning plate. The driving member and the clamping component adjust the angle and position of the can body to match the angle and position of the cover body according to the detection data. Finally, the capture and capping mechanism is started to complete the capping.

[0006] By adopting the above technical solution, the twin-screw conveyor line pushes the tank body to move, and the conveyor belt conveys the cover body to move, the tank body is pushed to the positioning plate, the twin-screw conveyor line stops running, the positioning component positions the tank body by magnetic attraction, the grabbing and pressing mechanism grabs the cover body for transportation, the detection component is used to detect the positions of both the cover body and the tank body, and according to the detection data, the driving member drives the positioning plate to rotate to adjust the angle of the tank body, and the clamping component is used to clamp the tank body to move and adjust the horizontal position of the tank body, so that the angle and position of the tank body are adapted to the angle and position of the cover body, and after the first adjustment is completed, the detection component continues to detect the position of the tank body, and continues to adjust when the position of the tank body does not meet the requirements until it meets the requirements and stops adjusting, and after all adjustments are completed, the clamping component moves away from the tank body, and the positioning plate continues to adsorb and position the tank body by magnetic attraction.

[0007] The grabbing and capping mechanism starts to perform the capping process, thereby completing the capping of the can body. Finally, the twin-screw conveyor line starts to push the capped can body forward to leave the positioning plate, and then the next can body continues to move forward to the positioning plate. At the same time, the grabbing and capping mechanism continues to grab the cap body for inspection and transportation, and then repeats the process, so that the capping can be completed continuously and automatically.

[0008] The can body is pushed to move by a twin-screw conveyor line, the capping mechanism grabs the cap, the detection component is used to detect the position of the can body and the cap, the positioning plate is used to adsorb and position the can body, the drive member drives to adjust the angle of the can body, and the clamping component is started to push the can body to move in the horizontal direction to overcome the magnetic attraction of the positioning plate on the can body, thereby greatly improving the accuracy of the position during capping, thereby improving the capping quality of the can body; and the clamping component is moved away from the can body before capping, which reduces the adverse effects of the clamping component on the capping, thereby further improving the capping quality of the can body.

[0009] In the present application, the positioning assembly is located on the lower surface of the positioning plate and uses magnetic attraction to position the can body. There is no need to set a clamping structure on the positioning plate, thereby reducing the interference caused by the twin-screw conveyor line pushing the can body to move. The drive member and the clamping assembly operate independently of each other, making the structure simple and stable. At the same time, there is no magnetic attraction after the can body is moved out of the positioning plate, which facilitates the movement of the can body, making the structure stable and time-saving, thereby improving the capping efficiency of the can body.

[0010] At the same time, the tank body is pushed to move by the twin-screw conveyor line. Because the twin-screw conveyor line is an arc-shaped surface, the minimum diameter of the twin-screw conveyor line is smaller than the outer diameter of the tank body, that is, the tank body can be pushed to move. Therefore, the maximum diameter of the twin-screw conveyor line can be larger than the diameter of the tank body, that is, because there is a gap between the twin-screw conveyor line and the tank body, it is convenient to adjust the tank body. Therefore, the tank body can be adjusted while driving it to move.

[0011] Optionally, an annular positioning groove is coaxially formed on the lower surface of the positioning plate, and the positioning assembly includes: A magnet ring is snap-fitted and mounted on the positioning groove and is used to adsorb and position the tank body; The positioning screw passes through the magnet ring and is threadedly connected to the positioning groove for positioning.

[0012] By adopting the above technical solution, the magnet ring can realize the adsorption and positioning of the can body. At the same time, the magnet ring is ring-shaped, so that the adsorption force on the can body moved onto the positioning plate is more uniform, and it is convenient to push the can body out of the positioning plate later, and it also reduces the probability of wear of the can body and the positioning plate in local areas due to uneven adsorption force. Furthermore, the ring-shaped magnet ring increases the range of the adsorption force, and the overall structure also improves the adsorption effect, thereby improving the stability of the can body during rotation and further improving the capping quality of the can body.

[0013] Optionally, mounting plates are provided on the machine body and on both sides of the tank conveying direction, and the clamping assembly includes: The first moving member and the second moving member are respectively arranged on two mounting plates and the piston rods are arranged opposite to each other; Two clamping plates are arranged on the piston rods of the first moving member and the second moving member, and arc-shaped clamping surfaces that fit the tank body are arranged on the side walls on the opposite sides.

[0014] By adopting the above technical scheme, according to the detection data, the first movable member and the second movable member are started at the same time to drive the two clamping plates to move, and the two clamping surfaces on the two clamping plates are clamped on the can body to realize the positioning of the can body along the moving direction of the can body, and at the same time, the position of the can body along the direction perpendicular to the moving direction of the can body can be positioned, so that the two clamping plates with clamping surfaces can realize the positioning of the can body in two directions perpendicular to each other, and after the tank body position adjustment is completed, the detection component can continue to detect until it ends after meeting the requirements, and the different moving distances of the two clamping plates can realize the positioning of the can body positions with different requirements, thereby further improving the pressure capping quality of the can body.

[0015] Optionally, a pressing surface and a positioning surface are provided on the side wall of the two clamping plates close to one side of the can body and above the clamping surface, the pressing surface is located above the positioning surface and is inclined, and the two clamping plates move away from the can body after clamping and positioning the can body, and during this process the pressing surface and the positioning surface do not contact the can body, and the grabbing and capping mechanism performs the capping process, the two clamping plates move back so that the two positioning surfaces clamp the cover body and the two clamping surfaces clamp the can body for positioning, and the grabbing and capping mechanism moves upward to separate from the cover body; when the cover body is not pressed into place, the pressing surface generates an inclined downward extrusion force on the cover and causes the cover body to be pressed into place.

[0016] By adopting the above technical solution, if there is still adsorption force when the grabbing and capping mechanism moves up and separates from the cover body, the already capped cover body is easily separated from the can body under the action of the adsorption force, or the grabbing and capping mechanism is also likely to cause the cover body to fail to be capped in place due to other reasons, thereby reducing the capping quality of the can body.

[0017] After the capping mechanism is started to press the cover onto the can body, the capping mechanism maintains its original state, and the two clamping plates approach the can body so that the two positioning surfaces are pressed against the cover body for positioning, and the two clamping surfaces continue to press against the can body for positioning. If the can body is displaced during the capping process, the clamping of the two clamping surfaces can further position the can body, and the squeezing force of the capping mechanism on the cover body at this time can continue to press the cover body that has not been pressed into place into place, and then the capping mechanism moves up and disengages from the cover body. Since the two positioning surfaces are positioned, the probability of driving the cover body to move up by the capping mechanism is reduced; furthermore, when the two clamping plates move back, when the cover is not pressed into place, that is, the cover body is in a higher position, the two squeezing surfaces can squeeze the cover body downwards so that the cover body is pressed into place, thereby further reducing the probability of the cover not being pressed into place and improving the capping quality of the can body.

[0018] Optionally, the two mounting plates are both vertically slidably mounted on the machine body through a sliding rod, and an adjustment assembly connected to the two sliding rods is provided on the machine body, and the adjustment assembly includes: An adjustment plate is arranged on the bottom ends of the two sliding rods; The adjusting screw is rotatably arranged on the machine body and is threadedly connected with the adjusting plate and is used for vertically adjusting the positions of the two mounting plates.

[0019] By adopting the above technical solution, the adjusting screw rotates to drive the adjusting plate to move, and the movement of the adjusting plate drives the two mounting plates to move simultaneously, thereby adjusting the position of the clamping assembly, thereby being able to clamp and adjust the position of tanks of different heights.

[0020] Optionally, the grabbing and capping mechanism comprises: A grabbing plate is rotatably arranged on the machine body; A rotating member, used for driving the grabbing plate to rotate; A plurality of gripping components are arranged in a circular array around the axis of the gripping disk's rotation direction and move vertically and are used to adsorb, grip and position the cover body. A detection station is formed at the position where the detection component detects the cover body. The gripping component grabs the cover body and then moves to the detection station for detection and then to the tank body for capping.

[0021] By adopting the above technical scheme, the rotating member drives the rotating disk and multiple grabbing components to rotate simultaneously, and the grabbing component moves down to grab the cover body when it rotates to the conveyor belt, and then the grabbing component and the cover body are rotated to the detection station to detect the position of the cover body. At the same time, the detection component also detects the position of the can body moved on the positioning disk, and then the driving member and the clamping component start to adjust the angle and position of the can body to match the angle and position of the cover body, and then the grabbing component and the cover body are rotated to the can body, and the grabbing component moves down to drive the cover body to be pressed onto the can body, thereby completing the pressing of the can body, and at the same time, multiple stations realize the grabbing, detection and pressing of the cover body, so the three processes are carried out simultaneously, which greatly reduces the time for pressing the can body, improves the pressing efficiency of the can body, and can leave enough time to adjust the position and angle of the can body, thereby improving the pressing quality of the can body.

[0022] Optionally, the grabbing component includes: A lifting member is arranged on the grabbing plate and a piston rod is arranged vertically downward; A lifting block is arranged on the piston rod of the lifting member; The suction cup is arranged on the lifting block and is used for adsorbing and positioning the cover body.

[0023] By adopting the above technical solution, the lifting member drives the lifting block to move vertically, the lifting block moves downward to drive the suction cup to move downward to adsorb the cover body, and then the lifting block moves upward to drive the suction cup and the cover body to move together, the lifting block moves downward to drive the cover body to be pressed onto the tank body, and then the suction cup releases the adsorption force on the cover body, and the lifting block moves upward to drive the suction cup to move upward, thereby completing the pressing of the tank body.

[0024] Optionally, a pressure-recombining component is provided on the machine body, and the pressure-recombining component includes: A re-pressing seat is vertically slidably arranged on the machine body; A spring is arranged on the machine body and connected to the pressure-compression seat; The re-pressing roller is rotatably mounted on the re-pressing seat and is located outside the positioning plate. The re-pressing roller re-presses the cover body after the cover is pressed under the action of a spring.

[0025] By adopting the above technical solution, the twin-screw conveyor line drives the can body to continue to move forward after capping, the can body moves to the outside of the positioning plate, and the can body moves to the re-pressing roller. The re-pressing roller continues to re-press the cover body under the action of the spring, thereby further reducing the probability of the cover body not being pressed into place and improving the capping quality of the can body.

[0026] Optionally, a plurality of the pressure-replenishing assemblies are arranged at intervals along the moving direction of the tank body, and the height of the pressure-replenishing assemblies gradually decreases along the moving direction of the tank body and are used to gradually increase the squeezing force on the cover body.

[0027] By adopting the above technical solution, the cover body is gradually squeezed through multiple re-pressing components, thereby improving the re-pressing effect of the re-pressing components and improving the pressing quality of the can body.

[0028] Optionally, a buzzer sensor is provided on the machine body, and a sensing rod is provided on the pressure-recombining seat. When the cover body is not pressed into place, the cover body pushes the pressure-recombining seat and the sensing rod upward, so that the sensing rod abuts against the buzzer sensor and causes the buzzer sensor to sound a buzzing alarm.

[0029] By adopting the above technical scheme, when the cover body is not pressed into place, the height of the cover body is increased, so the cover body pushes the re-pressing roller, the re-pressing seat and the sensing rod to move up at the same time. If the re-pressing roller is re-pressed by the spring and the cover body is pressed into place, the sensing rod cannot contact the buzzer sensor. On the contrary, the sensing rod abuts against the buzzer sensor and a buzzer alarm is sounded, thereby reminding the staff to inspect the equipment and remove defective products, thereby further improving the pressing quality of the can body.

[0030] In summary, the present application includes at least one of the following beneficial technical effects: 1. The can body is pushed to move by the twin-screw conveyor line, the grabbing and capping mechanism grabs the cap body, the detection component is used to detect the position of the can body and the cap body, the positioning plate is used to adsorb and position the can body, the driving member drives to adjust the angle of the can body, and the clamping component is started to push the can body to move in the horizontal direction to overcome the magnetic attraction of the positioning plate on the can body, thereby greatly improving the position accuracy during capping, thereby improving the capping quality of the can body; and the clamping component is kept away from the can body before capping, which reduces the adverse effects of the clamping component on the capping, thereby further improving the capping quality of the can body.

[0031] 2. The positioning assembly is arranged on the lower surface of the positioning plate and the tank body is positioned by magnetic attraction. There is no need to set a clamping structure on the positioning plate, thereby reducing the interference caused by the twin-screw conveyor line pushing the tank body to move. The drive and the clamping assembly operate independently of each other, making the structure simple and stable. At the same time, there is no magnetic attraction after the tank body is moved out of the positioning plate, which facilitates the movement of the tank body, making the structure stable and time-saving, thereby improving the capping efficiency of the tank body.

[0035] The embodiment of the present application discloses a can capping production line.

[0037] The twin-screw conveyor line 11 and the conveyor belt 12 are arranged at intervals and their conveying directions are parallel to each other.

[0038] Reference Figure 2-Figure 4The capping device 2 includes a positioning plate 21, a driving member 22, and a positioning assembly 3.

[0039] The positioning plate 21 is coaxially arranged with the mounting hole 15 and a rotational gap is left between the positioning plate 21 and the mounting hole 15. A coaxial annular positioning groove 23 is provided on the lower surface of the positioning plate 21. The positioning assembly 3 includes a magnet ring 31 and a positioning screw 32. The magnet ring 31 is snap-fitted and installed on the positioning groove 23 and is used to generate an adsorption force on the tank body moved onto the positioning plate 21; a plurality of positioning screws 32 are arranged in a circular array around the axis of the positioning plate 21, and the positioning screws 32 pass through the lower surface of the magnet ring 31 and are threadedly connected to the bottom of the positioning groove 23, so as to realize the positioning of the magnet ring 31.

[0040] The twin-screw conveyor line 11 pushes the two tanks to move simultaneously, so that the two tanks move to the two positioning plates 21. The two magnet rings 31 generate adsorption forces on the two tanks respectively and are positioned on the two positioning plates 21. The driving member 22 drives the positioning plates 21 to rotate, and the rotation of the positioning plates 21 is used to adjust the angle of the tanks.

[0041] Reference Figure 2-Figure 3 The capping device 2 also includes a clamping assembly 4, a grabbing and capping mechanism 7 and a detection assembly 6. A mounting plate 16 is vertically slidably installed on the upper surface of the body 1 and located on both sides of the twin-screw conveyor line 11 and corresponding to the two mounting holes 15 through a sliding rod 53. The mounting plate 16 is in a horizontal state and is located above the twin-screw conveyor line 11; the sliding rod 53 is fixedly installed on the lower surface of the mounting plate 16 and vertically slidably penetrates the upper surface of the body 1, and the bottom of the sliding rod 53 extends to the bottom of the body 1.

[0042] An adjustment assembly 5 connected to two sliding rods 53 is provided on the body 1, and 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 is rotatably connected to the lower surface of the body 1; the adjustment screw 52 rotates to drive the adjustment plate 51, the sliding rod 53 and the two mounting plates 16 to move vertically.

[0043] The clamping assembly 4 is arranged on two mounting plates 16 and is used to clamp the can body and move it to adjust the position of the can body. The grabbing and capping mechanism 7 is used to transport it after being adsorbed on the upper surface of the cover body by adsorption force; the detection assembly 6 is arranged on the machine body 1 and is used to detect the positions of the grasped cover body and the can body located on the positioning plate 21. The driving member 22 and the clamping assembly 4 adjust the angle and position of the can body to match the cover body according to the detection structure, and finally the grabbing and capping mechanism 7 is started to complete the capping.

[0044] Reference Figure 2 , Figure 3 , the clamping assembly 4 comprises a first moving member 41, a second moving member 42, and two clamping plates 43. The first moving member 41 and the second moving member 42 are both electric push rods and are fixedly mounted on the upper surfaces of the two mounting plates 16, respectively. The piston rods of the first moving member 41 and the second moving member 42 are relatively arranged to 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 relatively arranged. The first moving member 41 and the second moving member 42 are respectively used to drive the two clamping plates 43 to approach or move away from each other, and the moving direction of the two clamping plates 43 is perpendicular to the moving direction of the tank body. A control box for controlling the start and stop of the driving member 22, the first moving member 41 and the second moving member 42 is provided on the machine body 1, and the detection assembly 6 transmits detection data to the control box, and the control box controls the start and stop of the driving member 22, the first moving member 41 and the second moving member 42 according to the detection data.

[0045] Reference Figure 3 , Figure 5 The side walls of the two clamping plates 43 on the opposite side begin to have an arc-shaped clamping groove 49, and the bottom of the two clamping grooves 49 is coaxially provided with a protruding clamping block 44, and the side walls on the opposite side of the two clamping blocks 44 begin to have an arc-shaped clamping surface 45 that fits the tank body. The tops of the two clamping grooves 49 are coaxially provided with a pressing block 46, and the side walls on the opposite side of the two pressing blocks 46 begin to have a pressing surface 47 and a positioning surface 48 that are connected to each other, the pressing surface 47 is inclined and arc-shaped, and the bottom diameter of the pressing surface 47 is smaller than the top diameter; the positioning surface 48 is located below the pressing surface 47 and is annular, and the diameter of the positioning surface 48 is the same as the bottom diameter of the pressing surface 47.

[0046] Reference Figure 2 , Figure 3 , Figure 5 The two clamping plates 43 are close to each other, and when the two clamping surfaces 45 contact the can body, they will push the can body to move, so that the can body fits 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 body moves along two conveying directions perpendicular to and parallel to the can body to overcome the adsorption force of the magnet ring 31 on the can body, thereby adjusting the position of the can body from two perpendicular directions according to the detection structure of the detection component 6, so that the position and angle of the can body are adapted to the position and angle of the cover body.

[0047] After the adjustment is completed, the two clamping plates 43 move away from the tank body. At this time, the grabbing and pressing capping mechanism 7 starts to drive the cover body to move downward for the capping process, and then the grabbing and pressing capping mechanism 7 maintains the squeezing state of the cover body, and the two clamping plates 43 move back, so that the two positioning surfaces 48 are pressed against the outer wall of the cover body for positioning, and the two clamping surfaces 45 continue to press against the outer wall of the tank body for positioning.

[0048] When the position of the can body is displaced during the capping process, the two clamping surfaces 45 move back so that the can body can continue to move back to the correct position. Since the grabbing and pressing capping mechanism 7 maintains the downward squeezing force on the cover body, the cover body can continue to be pressed into place. Alternatively, when the grabbing and pressing capping mechanism 7 fails to press the cover body into place, that is, the position of the cover body is higher than the required position, the pressing surface 47 can first press against the upper surface of the cover body during the return movement of the two clamping plates 43, so that the two pressing surfaces 47 push the cover body into place, and then the two positioning surfaces 48 press against the cover body for positioning; at the same time, the two positioning surfaces 48 position the cover body, and then the grabbing and pressing capping mechanism 7 moves up and disengages from the cover body, thereby reducing the probability of driving the cover body to move up when the grabbing and pressing capping mechanism 7 moves up, thereby further improving the capping quality and efficiency of the can body.

[0049] Reference Figure 2 , Figure 4 A fixing plate 17 is fixedly installed on the machine body 1 between the twin-screw conveyor line 11 and the conveyor belt 12, and fixing plates 18 extending above the twin-screw conveyor line 11 are fixedly installed on both sides of the two mounting holes 15 on the machine body 1; the detection component 6 is provided with two capping detections corresponding to the two cover bodies respectively, and the detection component 6 includes a position detector 1 61 and a position detector 2 62, the position detector 1 61 is fixedly installed on the upper surface of the fixing plate 17, and the position detector 2 62 is fixedly installed on one of the fixing plates 2 18; the two position detectors 61 located on the fixing plate 17 are used to detect the positions of the two cover bodies grasped by the grasping and capping mechanism 7, and the two position detectors 2 62 located on the two fixing plates 2 18 are respectively used to detect the positions of the can bodies located on the two positioning plates 21.

[0050] The grabbing and capping mechanism 7 includes a grabbing plate 71, a rotating member 72 and a plurality of grabbing assemblies 73. The grabbing plate 71 is rotatably mounted on the machine body 1, the grabbing plate 71 is in a horizontal state and the axis of rotation is in a vertical state; the rotating member 72 is fixedly mounted on the machine body 1 and is used to drive the rotating plate to rotate. The rotating member 72 can be an air slip ring, which is a prior art and will not be described in detail here.

[0051] There are four grabbing assemblies 73 in number, and the four grabbing assemblies 73 are arranged in a circular array around the axis of the grabbing disk 71. Two opposite grabbing assemblies 73 are located above the conveyor belt 12 and the two mounting holes 15, and one of the grabbing assemblies 73 is located above the fixed plate 17. Two position detectors 61 located on the fixed plate 17, i.e., at the detection position of the cover body, form a detection station, and the grabbing assembly 73 moves vertically to adsorb, grab and position the cover body; the grabbing assembly 73 moves down to grab the two cover bodies and then moves up, and the grabbing disk 71 rotates to drive the grabbing assembly 73 and the two cover bodies to the two position detectors 61, and the two position detectors 61 are used to detect the angles and positions of the two cover bodies.

[0052] Reference Figure 2-Figure 4 At the same time, the twin-screw conveyor line 11 pushes the two can bodies onto the two positioning plates 21 for adsorption and positioning. The two position detectors 62 are used to detect the angles and positions of the two can bodies. Then the driving member 22 and the two clamping plates 43 move to adjust the positions of the two can bodies so that the positions and angles of the two can bodies match the positions and angles of the two cover bodies. The grabbing plate 71 drives the grabbing assembly 73 to move to the two can bodies. The grabbing assembly 73 moves down to press the two cover bodies onto the two can bodies. The grabbing assembly 73 moves up, and the cover bodies located on the three grabbing assemblies 73 are grabbed, detected and pressed at the same time.

[0053] The grabbing assembly 73 includes a lifting member 74, a lifting block 75 and a suction cup 76. The lifting member 74 is a lifting cylinder or an electric push rod. The lifting member 74 is fixedly mounted on the grabbing plate 71 and the piston rod is vertically downwardly arranged. The lifting block 75 is fixedly mounted on the piston rod of the lifting member 74 and is in a horizontal state. Two suction cups 76 are arranged at intervals and fixedly mounted on the lower surface of the lifting block 75. The two suction cups 76 are used to absorb air for adsorbing and transporting the two cover bodies, or the two suction cups 76 are deflated to release the adsorption of the cover bodies.

[0054] Reference Figure 2 , Figure 6 A mounting seat 19 is fixedly installed on the machine body 1, which extends above the twin-screw conveyor line 11 and is located on one side of the two positioning plates 21. The twin-screw conveyor line 11 is started to push the two can bodies that have been pressed to move to the bottom of the mounting seat 19; a plurality of re-pressing components 8 are arranged on the mounting seat 19 at intervals along the conveying direction of the can bodies. The re-pressing components 8 are used to re-press the cover bodies, and the heights of the plurality of re-pressing components 8 are gradually reduced along the conveying direction of the can bodies and are used to gradually increase the extrusion force on the cover bodies.

[0055] The re-pressure assembly 8 includes a re-pressure seat 81, a spring 82 and a re-pressure roller 83. The re-pressure seat 81 is vertically slidably installed on the mounting seat 19, a mounting block 84 is fixedly installed on the body 1 and located above the re-pressure seat 81, a buzzer sensor 85 is fixedly installed on the body 1 and located above the mounting block 84, and a sensing rod 86 is fixedly installed on the upper surface of the re-pressure seat 81 and vertically slidably penetrates the mounting block 84; the spring 82 is sleeved on the sensing rod 86 and its two ends are fixedly connected to the mounting block 84 and the opposite side walls of the re-pressure seat 81, and the spring 82 pushes the re-pressure seat 81 to maintain a downward trend; the re-pressure roller 83 is rotatably installed on the re-pressure seat 81, and the re-pressure roller 83 is in a horizontal state, and the axis of the re-pressure roller 83 is perpendicular to the moving direction of the tank body.

[0056] The can body and the cover body move under the re-pressing roller 83, and the re-pressing roller 83 is pressed against the cover body under the action of elastic force to squeeze it again. The cover body will push the re-pressing roller 83, the re-pressing seat 81 and the sensing rod 86 to move upward. When the re-pressing roller 83 is in the process of re-pressing the cover body, the cover is still not in place, that is, the height of the cover body is relatively high, the cover body pushes the sensing rod 86 to move upward and press against the buzzer sensor 85, and the buzzer sensor 85 sounds an alarm, thereby reminding the staff to pay attention to the equipment operation in time and reject unqualified can bodies.

[0057] The working principle of the embodiment of the present application is as follows: The twin-screw conveyor line 11 pushes the two tank bodies to move simultaneously, so that the two tank bodies are moved to the two positioning plates 21 for positioning, and the twin-screw conveyor line 11 stops running. The two position detectors 62 are used to detect the angles and positions of the two tank bodies. At the same time, the two suction cups 76 move down to grab the two cover bodies and then move up. The grabbing plate 71 rotates to drive the two cover bodies to the two position detectors 61 for detection. The driving member 22 and the two clamping plates 43 move at the same time to adjust the angle and position of the tank body to adapt to the angle and position of the cover body, and the two clamping plates 43 move away from the tank body at the same time.

[0058] The grabbing plate 71 rotates to drive the two suction cups 76 and the two cover bodies to the two can bodies, and the two suction cups 76 move downward to drive the two cover bodies to move downward, and the two cover bodies are placed on the two can bodies. The two suction cups 76 maintain the squeezing state on the cover bodies, and the two clamping plates 43 move back to clamp on the can bodies and the cover bodies. The two suction cups 76 release the adsorption force and move upward, and the grabbing plate 71 continues to rotate, thereby completing the pressing of the can bodies.

[0059] The twin-screw conveyor line 11 is started to push the two can bodies to move, so that the two can bodies are moved to the outside of the positioning plate 21 and then re-pressed by multiple re-pressing rollers 83 in turn, so that the cover body can be squeezed again. When the cover body is still not pressed into place after squeezing, the re-pressing roller 83 moves up so that the sensing rod 86 abuts against the buzzer sensor 85 to sound a buzzer alarm, thereby increasing the staff's attention to the equipment operation status and removing unqualified can bodies, thereby improving the quality and efficiency of the can body pressing.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
