Description

Technical Field

[0001] This utility model relates to the field of automated tooling production equipment technology, and in particular to a capping device for a filling production line. Background Technology

[0002] In recent years, more and more high-end daily chemical products have adopted colorful bottle packaging, which greatly enhances the packaging grade of the products and makes them more popular.

[0003] In the filling and sealing production line, bottled products need to complete a series of operations, including empty bottle feeding, cleaning, filling, weighing, and capping. In automated packaging processes, such as for powder boxes and beverage bottles, the caps need to be screwed into the threaded bottle body. Before screwing, the caps to be threaded need to be gripped and fed into the bottle body, and then the capping operation is performed using tools.

[0004] Traditional capping operations often involve separate loading and capping processes. First, the cap is loaded, and then the capping mechanism screws it on. This design is complex, requiring two sets of gripper structures. Furthermore, the conventional method for capping utilizes the clamping components on the existing mold conveyor mechanism. However, during production line operation, due to weight requirements, the clamping components on the mold conveyor mechanism need to be released. Without these clamps, the traditional capping machine cannot perform the capping operation.

[0005] In order to adapt to the automated capping operation of the production line, it is urgent to design a capping device for the filling production line that can fully realize the automated capping of threaded caps. Utility Model Content

[0006] Purpose of the utility model: In view of the problems existing in the prior art, this utility model provides a capping device for a filling production line, which realizes the gripping and capping operation by only the capping claw of the first multi-station capping mechanism, and achieves the relative stability of the bottle during capping by the designed first bottle clamping mechanism.

[0007] Technical solution: This utility model provides a capping device for a filling production line, including a first workbench, on which a mold conveying mechanism is provided, and pairs of clamping members are spaced apart on the mold conveying mechanism; the first workbench is also provided with a cap conveying line facing the mold conveying mechanism and a first multi-station capping mechanism disposed between the cap conveying line and the mold conveying mechanism; a first bottle clamping mechanism is also provided on the mold conveying mechanism at a position directly opposite to the first multi-station capping mechanism; The first multi-station capping mechanism includes capping jaws and a rotary motor for driving the capping jaws to rotate. The first multi-station capping mechanism is also provided with a first driving member for driving the capping jaws to move left and right, up and down, and forward and backward. The first bottle clamping mechanism includes a clamping head facing the bottle on the mold conveying mechanism and a bidirectional clamping cylinder for driving the clamping head to clamp. The first bottle clamping mechanism is also provided with a second driving member arranged along the transmission direction of the mold conveying mechanism.

[0008] Furthermore, on the first workbench, a second multi-station capping mechanism with the same structure as the first multi-station capping mechanism is also provided on one side of the first multi-station capping mechanism. The second multi-station capping mechanism is provided on a third driving member that drives the capping gripper to move left and right and up and down. A second bottle holding mechanism with the same structure as the first bottle holding mechanism is also provided at a position directly opposite the second multi-station capping mechanism. The second bottle holding mechanism is also provided on a fourth driving member that is arranged along the transmission direction of the mold conveying mechanism.

[0009] Furthermore, a temporary receiving mechanism for the cover is provided between the cover conveyor line and the mold conveying mechanism, including a temporary receiving platform that matches the surface height of the cover conveyor line. A limiting platform is provided on the upper surface of the temporary receiving platform. A circular groove is provided at the position where the limiting platform and the temporary receiving platform are directly opposite each other, and a notch is provided on the side facing the cover conveyor line. The temporary receiving platform and the limiting platform are both provided on the fifth driving member arranged along the conveying direction of the mold conveying mechanism.

[0010] Furthermore, the cap-screwing gripper is a pneumatic gripper, and a vacuum suction cup is also connected through the middle of the cap-screwing gripper. The vacuum suction cup is connected to a vacuum generator, and the upper end of the pneumatic gripper is connected to the actuator of the rotary motor.

[0011] Furthermore, the pneumatic gripper is a pneumatic three-jaw structure, which includes three arc-shaped grippers that form a circle, with the vacuum suction cup located in the middle of the three arc-shaped grippers.

[0012] Furthermore, the first driving component includes a first electric longitudinal slide rail and a first electric transverse slide rail. Multiple cap-screwing claws are slidably mounted on the first electric longitudinal slide rail via a first claw fixing plate. The first electric longitudinal slide rail is slidably mounted on the first electric transverse slide rail, and the first electric transverse slide rail is fixed to a first adjusting plate. The first driving component also includes a pair of first front and rear slide rails mounted on the second workbench and arranged along the conveying direction of the cap conveying line, and a rack located on one side of the first front and rear slide rails. The rack meshes with a gear, which is driven by a first driving motor. The first adjusting plate slides on the pair of first front and rear slide rails.

[0013] Furthermore, the second and fourth driving components have the same structure, both including a second electric transverse slide rail arranged along the direction of the mold conveying mechanism, a second adjusting plate slidably arranged on the second electric transverse slide rail, and the bidirectional clamping cylinder fixed on the second adjusting plate.

[0014] Furthermore, the third driving component includes a third electric transverse slide rail arranged along the direction of the mold conveying mechanism and a second electric longitudinal slide rail slidably arranged on the third electric transverse slide rail. A second gripper fixing plate is slidably arranged on the second electric longitudinal slide rail. The second multi-station capping mechanism is fixed on the second gripper fixing plate and the capping gripper of the second multi-station capping mechanism is directly above the mold conveyor mechanism.

[0015] Furthermore, the fifth driving component includes a transverse slide rail fixed to the first worktable and arranged along the transmission direction of the mold conveying mechanism, and a first cylinder. The temporary receiving platform and the limiting platform are slidably arranged on the transverse slide rail through the first support frame, and the actuating end of the first cylinder is connected to the first support frame.

[0016] Furthermore, the limiting platform is also disposed on the front and rear fine-tuning components and the longitudinal fine-tuning components; the front and rear fine-tuning components include a second front and rear slide rail disposed on the surface of the first support frame, the second support frame is slidably disposed on the second front and rear slide rail, and a threaded rod is connected to the first support frame through a first support, and a threaded bushing is connected to the second support frame through a second support, the threaded rod and the threaded bushing being threadedly connected; the limiting platform is connected to the actuating end of the lifting cylinder, and the lifting cylinder is vertically fixed on the second support frame.

[0017] Furthermore, the cover transmission line is provided with several pairs of limiting bars, and the starting end limiting bar bends outward to form an arc-shaped guide bar.

[0018] Furthermore, a height limiting plate is fixed above the cover transmission line, and the distance between the height limiting plate and the cover transmission line is greater than the cover thickness but less than two cover thicknesses.

[0019] Furthermore, the first multi-station capping mechanism is also equipped with a displacement detection plate, and a photoelectric detection switch is provided on one side of the displacement detection plate.

[0020] Beneficial effects:

[0021] 1. This utility model achieves the gripping and capping operations solely through the capping claw of the first multi-station capping mechanism. Its simple structural design allows for the completion of the entire loading and capping operation through a single control system. Furthermore, the first bottle-holding mechanism ensures relative stability of the bottle during capping, without affecting the start / stop operations of other parts of the production line on the mold conveying mechanism.

[0022] 2. This utility model provides a second multi-station capping mechanism on one side of the first multi-station capping mechanism. The purpose is that if the production line capacity is normal, only the first multi-station capping mechanism is executed to realize the functions of cap removal, cap placement, and tightening. The second multi-station capping mechanism is not activated. However, if the production line capacity is high, the first multi-station capping mechanism can realize the functions of cap removal, cap placement, and pre-screwing (the cap is not tightened). The second multi-station capping mechanism is activated, and the tightening operation is realized based on the first multi-station capping mechanism. Therefore, the second multi-station capping mechanism designed in this utility model can increase the production line capacity.

[0023] 3. This utility model also includes a temporary cover receiving mechanism between the cover conveyor line and the mold conveying mechanism. The covers conveyed on the cover conveyor line reach their end and enter the temporary receiving platform of the temporary receiving mechanism, where they are limited by a limiting platform. At this point, the fifth driving component drives the temporary receiving platform and the limiting platform to shift, allowing the cover conveyor line to continue conveying while preventing the covers from moving forward. This ensures that only one set of covers is on the temporary receiving mechanism, facilitating material handling and loading.

[0024] 4. The capping gripper designed in this utility model is a pneumatic gripper. The pneumatic gripper enables the gripping and tightening of the cap. A vacuum suction cup is incorporated in the middle of the capping gripper. This allows the vacuum suction cup to pick up the cap during loading, facilitating the loading operation. The capping gripper does not need to operate at this time; after the vacuum suction cup has picked up the cap, the capping gripper is used to tighten the cap. 5. This utility model uses a pneumatic three-jaw structure for capping operation, which can ensure the stability of the force during the capping operation. The vacuum suction cup and the capping jaws are set together and driven and controlled by a first driving component, which reduces the number of workstations and makes the control simpler.

[0025] 6. In this invention, when driving the capping gripper, the first electric longitudinal slide rail enables the capping gripper to move up and down, and the first electric transverse slide rail drives the capping gripper to move along the conveying direction of the mold conveying mechanism when capping, achieving precise control. Meanwhile, the first drive motor drives the gear to rotate, enabling the first adjusting plate to slide on the first front and rear slide rails, adjusting the capping gripper to move back and forth between the cap conveying line and the mold conveying mechanism, thus achieving feeding control.

[0026] 7. When controlling the first and second bottle clamping mechanisms, this utility model uses a bidirectional clamping cylinder to drive the clamping head to clamp the bottle. During clamping, the position can be adjusted by the second or fourth driving component. It can also move the clamping head with the transmission direction of the mold conveying mechanism to achieve non-stop capping operation.

[0027] 8. The second multi-station capping mechanism designed in this utility model does not require front and rear drive when capping the cap body. It only needs to realize the transmission along the direction of the mold conveying mechanism and the up and down transmission. That is, when assembling the equipment, the capping gripper of the second multi-station capping mechanism is directly above the mold conveying mechanism. Because the second multi-station capping mechanism does not need to load the cap body, it only needs to realize the capping operation.

[0028] 9. The fifth driving component designed in this utility model enables the temporary receiving platform and the limiting platform to slide left and right, thus avoiding the conveying path of the cover conveyor line. Furthermore, to accommodate cover screwing of different sizes, a front-to-back fine-tuning component and a longitudinal fine-tuning component are designed. The front-to-back fine-tuning component is designed to accommodate cover diameters of different sizes. When the cover diameter changes, the upper temporary receiving platform and the limiting platform need to be replaced. After replacement, the threaded rod rotates within the threaded bushing, pushing the threaded bushing and its connected second support frame to slide on the second front and rear slide rails, achieving front-to-back fine-tuning. When the cover thickness changes, the upper temporary receiving platform and the limiting platform also need to be replaced. After replacement, the overall height of the temporary receiving platform is adjusted by a lifting cylinder, simultaneously driving the limiting platform to adjust up and down, thus accommodating cover heights of different sizes. The limiting platform and the first support frame of this utility model can slide up and down without obstructing the height adjustment of the limiting platform.

[0029] 10. This utility model is provided with several pairs of limiting bars, forming several sets of cover transmission channels. The cover can be transmitted forward between the pairs of limiting bars. Each set of cover transmission channels is correspondingly set with the cap-screwing claw. In addition, the height limiting plate on the top can limit the transmission channel to only one cover at a time, so that the covers will not be stacked.

[0030] 11. The displacement detection plate of this utility model will have a detection displacement during the downward movement to ensure that the cap is moved into place before the cap is screwed on, so as to ensure that the cap and the bottle are pressed tightly together.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] Example 1:

[0038] See Figure 1 This utility model discloses a capping device for a filling production line, including a first workbench 1, a mold conveying mechanism 3 on the first workbench 1, and pairs of clamping parts 301 spaced apart on the mold conveying mechanism 3; the first workbench 1 is also provided with a cap conveying line 2 facing the mold conveying mechanism 3 and a first multi-station capping mechanism 4 disposed between the cap conveying line 2 and the mold conveying mechanism 3; a first bottle clamping mechanism 5 is also provided directly above the mold conveying mechanism 3 and opposite to the first multi-station capping mechanism 4.

[0039] The first multi-station capping mechanism 4 includes a capping gripper 401 and a rotary motor 402 for driving the capping gripper 401 to rotate. The first multi-station capping mechanism 4 also includes a first driving member for driving the capping gripper 401 to move left and right, up and down, and forward and backward. The first bottle clamping mechanism 5 includes a clamping head 501 facing the bottle 10 on the mold conveying mechanism 3 and a bidirectional clamping cylinder 502 for driving the clamping head 501 to clamp. The first bottle clamping mechanism 5 also includes a second driving member arranged along the transmission direction of the mold conveying mechanism 3. The bidirectional clamping cylinder 502 is fixed by a bracket, and the clamping head 501 connected to the bidirectional clamping cylinder 502 can just clamp the bottle 10 on the mold conveying mechanism 3.

[0040] In this embodiment, see Figure 8 and Figure 9 The cap-screwing gripper 401 is a pneumatic gripper, with a vacuum suction cup 403 connected through its center. The vacuum suction cup 403 is connected to a vacuum generator 404, and the upper end of the pneumatic gripper is connected to the actuator of a rotary motor 402. In this embodiment, the pneumatic gripper is a three-jaw pneumatic structure, comprising three arc-shaped grippers forming a circle, with the vacuum suction cup 403 located in the center of the three arc-shaped grippers. After the pneumatic three-jaw structure grips the cap 9, it drives the cap 9 to rotate via the rotary motor 402, completing the cap-screwing operation.

[0041] In this embodiment, the first driving component includes a first electric longitudinal slide rail 405 and a first electric transverse slide rail 406. Multiple cap-screwing claws 401 are slidably disposed on the first electric longitudinal slide rail 405 via a first claw fixing plate 407. The first electric longitudinal slide rail 405 is slidably disposed on the first electric transverse slide rail 406. The first electric transverse slide rail 406 is fixed on a first adjusting plate 408. The first driving component also includes a pair of first front and rear slide rails 410 disposed on the second workbench 409 and arranged along the transmission direction of the cap transmission line 2, and a rack 411 located on one side of the first front and rear slide rails 410. The rack 411 meshes with a gear 412, and the gear 412 is driven and connected by a first driving motor 413. The first adjusting plate 408 slides on the pair of first front and rear slide rails 410. The first drive motor 413 drives the gear 412 to rotate, causing the gear 412 to move along the rack 411. This causes the first adjusting plate 408 to slide on the first front and rear slide rails 410, thereby moving the first electric longitudinal slide rail 405, the first electric transverse slide rail 406, and the first multi-station capping mechanism 4 on them back and forth. The first electric longitudinal slide rail 405 drives the capping gripper 401 on it to move up and down, and the first electric transverse slide rail 406 drives the first electric longitudinal slide rail 405 and the capping gripper 401 on it to move left and right, completing the drive adjustment of three degrees of freedom.

[0042] In this embodiment, the second driving component includes a second electric transverse slide rail 503 arranged along the direction of the mold conveying mechanism 3. A second adjusting plate 504 is slidably arranged on the second electric transverse slide rail 503, and a bidirectional clamping cylinder 502 is fixed on the second adjusting plate 504. During operation, the bidirectional clamping cylinder 502 drives the clamping head 501 to clamp the bottle body 10, and the bottle body 10 on it moves along the conveying direction of the mold conveying mechanism 3 via the second electric transverse slide rail 503, thereby realizing the capping operation while conveying the bottle.

[0043] A temporary cover receiving mechanism 8 is also provided between the cover conveyor line 2 and the mold conveying mechanism 3. This mechanism includes a temporary receiving platform 801 whose surface height matches that of the cover conveyor line 2. A limiting platform 802 is provided on the upper surface of the temporary receiving platform 801. A circular groove is provided directly opposite the limiting platform and the temporary receiving platform 801, and a notch is provided on the side facing the cover conveyor line 2. Both the temporary receiving platform 801 and the limiting platform 802 are located on the fifth driving component along the conveying direction of the mold conveying mechanism 3.

[0044] In this embodiment, the fifth driving component includes a transverse slide rail 803 fixed to the first workbench 1 and arranged along the transmission direction of the mold conveying mechanism 3, and a first cylinder 804. A temporary receiving platform 801 and a limiting platform 802 are slidably mounted on the transverse slide rail 803 via a first support frame 805. The actuating end of the first cylinder 804 is connected to the first support frame 805. (See also...) Figure 4 After the first cylinder 804 extends or retracts, the first support frame 804 moves left and right on the transverse slide rail 803, causing the temporary receiving platform 801 and the limiting platform 802 on it to also move left and right.

[0045] Considering the different sizes of the cover 9, it is necessary to replace the temporary receiving platform 801 and the limiting platform 802 to adapt to the diameter and thickness of the cover 9. In this embodiment, the limiting platform 802 is set on the front and rear fine adjustment components and the longitudinal fine adjustment components. The front and rear fine adjustment components include a second front and rear slide rail 806 set on the surface of the first support frame 805. The second support frame 807 is slidably set on the second front and rear slide rail 806, and a threaded rod 810 is connected to the first support frame 805 through a first support 808. A threaded bushing 811 is connected to the second support frame 807 through a second support 809. The threaded rod 810 and the threaded bushing 811 are threadedly connected. The limiting platform 802 is connected to the execution end of the lifting cylinder 812, and the lifting cylinder 812 is vertically fixed on the second support frame 807. Before adjustment, replace the temporary receiving platform 801 and the limiting platform 802. During lifting adjustment, the lifting cylinder 812 drives the temporary receiving platform 801 and the limiting platform 802 to rise or fall. At this time, the limiting platform 802 can be slidably connected with the first support frame 805. During front-back adjustment, by rotating the threaded rod 810, the threaded bushing 811 drives the second support frame 807 on it to slide back and forth, thus completing the front-back adjustment. The purpose of the front-back adjustment is to bring it closer to the cover transmission line 2. During height adjustment, it is made to match the surface height of the cover transmission line 2.

[0046] Several sets of limiting bars 201 are arranged in pairs on the cover conveyor line 2, and the starting end limiting bar 201 bends outward to form an arc-shaped guide bar. During the conveying of the cover 9, the cover 9 is conveyed forward through the channel between each pair of limiting bars 201 until it reaches the end of the cover conveyor line 2 and is transferred to the cover temporary receiving mechanism 8. A height limiting plate 202 is fixed above the cover conveyor line 2, and the distance between the height limiting plate 202 and the cover conveyor line 2 is greater than the thickness of one cover 9 and less than the thickness of two cover 9s.

[0047] The first multi-station capping mechanism 4 is also equipped with a displacement detection plate 414, and a photoelectric detection switch 415 is located on one side of the displacement detection plate 414. After the first multi-station capping mechanism 4 transfers the cap 9 onto the bottle 10 under the action of the first driving component, it needs to ensure that the cap 9 and the bottle 10 are pressed together to facilitate the subsequent capping operation. Therefore, during the downward movement of the capping gripper 401, the displacement detection plate 414 moves down accordingly. When the photoelectric detection switch 415 detects the displacement detection plate 414, it indicates that the displacement is in place and the bottle is in a pressed state. Then, the capping gripper 401 is used to clamp the cap 9 and tighten it.

[0048] The mold conveying mechanism 3 used in this embodiment participates in the construction. Figure 11 The mold conveying mechanism 3 includes a first conveyor belt 303 and a second conveyor belt 304. The first conveyor belt 303 is provided with left clamping members at intervals, and the second conveyor belt 304 is provided with right clamping members. The clamping heads of each pair of left clamping members and right clamping members are arranged facing each other.

[0049] In this embodiment, the first conveyor belt conveyor 303 and the second conveyor belt conveyor 304 have the same structure, both including a main drive pulley 305, a driven pulley 306, and a conveyor belt 307 located between the main drive pulley 305 and the driven pulley 306. The main drive pulley 305 is driven by a second drive motor 308. The conveyor belts 307 of both are located on the same horizontal line and are driven synchronously by the second drive motor 308.

[0050] When the mold conveying mechanism 3 clamps the bottle 10, the distance between the left and right clamping parts is slightly larger than the diameter of the bottle 10. During clamping, the first conveyor belt 303 moves a small distance from left to right, and the second conveyor belt 304 moves a small distance from right to left. The left and right clamping parts approach each other, clamping the bottle 10. After clamping, the first and second conveyor belts 303 and 304 move forward synchronously. Upon reaching the capping station, the first and second conveyor belts 303 and 304 stop moving. Then, the first conveyor belt 303 moves slightly in the reverse direction, and the second conveyor belt 304 continues to move slightly in the forward direction. At this time, the left and right clamping parts separate, releasing the bottle 10 clamping operation. Afterward, the bottle can be clamped through the first bottle clamping mechanism 5.

[0051] Working principle of Example 1: 1. The cover 9 is placed on the cover conveyor line 2 and transported forward. At this time, the temporary receiving platform 801 and the limiting platform 802 of the cover temporary receiving mechanism 8 are misaligned with the cover conveyor line 2. When the cover 9 is transferred to the end of the cover conveyor line 2, it cannot be transferred into the cover temporary receiving mechanism 8.

[0052] 2. When the capping operation begins, the first cylinder 804 operates, driving the temporary receiving platform 801 and the limiting platform 802 to move to a position directly opposite the conveying channel of the cap conveying line 2. At this time, the cap 9 on the cap conveying line 2 is transferred to the temporary receiving platform 801. The first cylinder 804 continues to operate, pushing the temporary receiving platform 801 and the limiting platform 802 to move to a position offset from the conveying channel of the cap conveying line 2.

[0053] 3. The first driving component is activated, the vacuum generator 404 operates, and the vacuum suction cup 403 picks up the cap 9 from the temporary receiving platform 801 and transfers it to the bottle 10 on the mold conveying mechanism 3, pressing the cap 9 into place. During this process, the bidirectional clamping cylinder 502 drives the clamping head 501 to clamp the bottle 10.

[0054] 4. After the cap 9 is pressed into place, the capping gripper 401 is activated to hold the cap 9, and the rotary motor 402 is activated to drive the capping gripper 401 to tighten. During operations 3 and 4, the first electric transverse slide rail 406 and the second electric transverse slide rail 503 can be activated simultaneously to drive the first multi-station capping mechanism 4 and the first bottle clamping mechanism 5 to move forward with the mold conveying mechanism 3.

[0055] 5. After tightening, the first multi-station capping mechanism 4 and the first bottle clamping mechanism 5 return to their original positions and continue the next round of capping operation.

[0056] Example 2:

[0057] The difference between this embodiment and embodiment 1 is that: on the first workbench 1, on one side of the first multi-station capping mechanism 4, a second multi-station capping mechanism 6 with the same structure as the first multi-station capping mechanism 4 is also provided. The second multi-station capping mechanism 6 is provided in the third driving member that drives the capping gripper 401 to move left and right and up and down. A second bottle holding mechanism 7 with the same structure as the first bottle holding mechanism 5 is also provided in the position directly opposite to the second multi-station capping mechanism 6. The second bottle holding mechanism 7 is also provided in the fourth driving member that is arranged along the transmission direction of the mold conveying mechanism 3.

[0058] The third driving component includes a third electric transverse slide rail 601 arranged along the direction of the mold conveying mechanism 3 and a second electric longitudinal slide rail 602 slidably arranged on the third electric transverse slide rail 601. A second gripper fixing plate 603 is slidably arranged on the second electric longitudinal slide rail 602. The second multi-station capping mechanism 6 is fixed on the second gripper fixing plate 603 and the capping gripper 401 of the second multi-station capping mechanism 7 is directly above the mold conveying mechanism 3.

[0059] The fourth drive component has the same structure as the second drive component, and will not be described in detail here.

[0060] Working principle of Example 2: 1. The cover 9 is placed on the cover conveyor line 2 and transported forward. At this time, the temporary receiving platform 801 and the limiting platform 802 of the cover temporary receiving mechanism 8 are misaligned with the cover conveyor line 2. When the cover 9 is transferred to the end of the cover conveyor line 2, it cannot be transferred into the cover temporary receiving mechanism 8.

[0061] 2. When the capping operation begins, the first cylinder 804 operates, driving the temporary receiving platform 801 and the limiting platform 802 to move to a position directly opposite the conveying channel of the cap conveying line 2. At this time, the cap 9 on the cap conveying line 2 is transferred to the temporary receiving platform 801. The first cylinder 804 continues to operate, pushing the temporary receiving platform 801 and the limiting platform 802 to move to a position offset from the conveying channel of the cap conveying line 2.

[0062] 3. The first driving component is activated, the vacuum generator 404 operates, and the vacuum suction cup 403 picks up the cap 9 from the temporary receiving platform 801 and transfers it to the bottle 10 on the mold conveying mechanism 3, pressing the cap 9 into place. During this process, the bidirectional clamping cylinder 502 drives the clamping head 501 to clamp the bottle 10.

[0063] 4. After the cap 9 is pressed into place, the capping gripper 401 is activated to hold the cap 9, and the rotary motor 402 is activated to drive the capping gripper 401 to pre-rotate. During operations 3 and 4, the first electric transverse slide rail 406 and the second electric transverse slide rail 503 can be activated simultaneously to drive the first multi-station capping mechanism 4 and the first bottle clamping mechanism 5 to move forward with the mold conveying mechanism 3.

[0064] 5. After pre-rotation, the first multi-station capping mechanism 4 and the first bottle clamping mechanism 5 both release their corresponding structures. The bottle 10 and the pre-capped body 9 move forward with the mold conveying mechanism 3. During this process, the clamping component 301 of the mold conveying mechanism 3 clamps the bottle 10 and moves it forward until it reaches the position of the second multi-station capping mechanism 6. The second multi-station capping mechanism 6 and the second bottle clamping mechanism 7 then begin to work. The rotating jaw 401 of the second multi-station capping mechanism 6 clamps the cap 9, and the second bottle clamping mechanism 7 clamps the bottle 10, thus achieving the tightening operation. During this process, the third electric transverse slide rail 601 and the second electric transverse slide rail 503 of the fourth drive component both drive the second multi-station capping mechanism 6 and the second bottle clamping mechanism 7 to move left and right with the mold conveying mechanism 3.

[0065] 6. After tightening, the second multi-station capping mechanism 6 and the second bottle clamping mechanism 7 return to their original positions to await the next round of tightening operation.
