Description

Technical Field

[0001] This utility model relates to the field of automated production technology, and in particular to a servo-driven automatic capping device. Background Technology

[0002] Filling technology is widely used in food, chemical, pharmaceutical, agricultural breeding, and laboratory research industries. Filling is an integral part of industrial production, requiring the filling of products such as paints, pigments, cosmetics, and cosmetics. For example, in the production of lotions, skincare products, and makeup, capping the filled bottles is necessary. Currently, these steps require manual operation. When producing large quantities of canned cosmetics, manual operation not only reduces production efficiency but also increases labor costs. Therefore, there is a need for automated cosmetic filling production lines to achieve large-scale production and meet the demands of automation.

[0003] There are also automated capping machines on the market, but existing automated machines often require the conveyor belt to stop before using a screwing device to screw the caps, which greatly affects production efficiency.

[0004] The utility model patent with application number 2024230932023 and patent name is "Automatic Bottle Cap Twisting Device". It discloses an automated twisting device that can achieve automated capping operation without stopping the conveyor belt during the bottle cap twisting process. However, the driving method is based on the meshing of gears and racks. The motor drives the gears to rotate, which drives the whole device to move forward and backward, and up and down. In actual production, the stroke of the gear and rack meshing is determined by the number of teeth. That is to say, its minimum stroke is one tooth, which makes it difficult to achieve high-precision control such as stopping and starting at will, and moving left and right, up and down at any time. Utility Model Content

[0005] Purpose of the utility model: In view of the problems existing in the prior art, this utility model provides a servo-driven automatic capping device, which achieves precise capping control through servo motor drive.

[0006] Technical Solution: This utility model provides a servo-driven automatic capping device, including at least one set of bottle stabilizing grippers and cap screwing grippers. The bottle stabilizing grippers are driven by gripper cylinders, and the cap screwing grippers are driven by rotary motors. The bottle stabilizing grippers and cap screwing grippers are mounted on a transverse driving member, which is mounted on a longitudinal driving member. The transverse driving member is mounted on a pair of guide rods that vertically penetrate the worktable. The lower ends of the pair of guide rods are connected by a connecting rod. The longitudinal driving member includes a first driving motor and a vertically mounted pulley assembly that is driven and connected to a first driving mechanism. The connecting rod is fixed to the belt of the pulley assembly.

[0007] Furthermore, the lateral drive component is a lead screw guide rail, which is driven by a second drive motor.

[0008] Furthermore, at least one set of bottle stabilizing grippers and bottle cap screwing grippers are connected to the transverse drive member via the first connecting plate. The transverse drive member drives the first connecting plate and the bottle stabilizing grippers and bottle cap screwing grippers on it to move back and forth along the transmission direction of the bottle conveyor line, and the transmission speed is the same as the transmission speed of the bottle conveyor line. The longitudinal drive member drives the transverse drive member to move up and down.

[0009] Furthermore, a second connecting plate is vertically arranged on one side of the first connecting plate, and a first slide rail is vertically arranged on one side of the second connecting plate. The first connecting plate is slidably connected to the first slide rail by a first slider. The bottle stabilizing gripper is arranged on the other side of the second connecting plate, and the lower end of the second connecting plate is slidably connected to the second slide rail by a second slider. The sliding extension direction of the second slide rail is consistent with the sliding extension direction of the transverse driving member.

[0010] Furthermore, the first connecting plate is connected to two bottle stabilizing grippers, and the second connecting plate is provided with bottle cap screwing grippers that are paired with the bottle stabilizing grippers.

[0011] Furthermore, the second connecting plate is also provided with a height adjustment component for adjusting the height of the bottle stabilizing gripper.

[0012] Furthermore, the height adjustment assembly includes a fixing block fixed to the second connecting plate, a lead screw threaded through the fixing block, the end of the lead screw being rotatably connected to a third connecting plate located below the fixing block via a bearing, an adjustment handwheel fixedly mounted on the top of the lead screw, and the gripper cylinder mounted on the third connecting plate.

[0013] Furthermore, a pair of guide posts are also inserted through the fixing block, and the lower ends of the pair of guide posts are fixedly connected to the third connecting plate.

[0014] Furthermore, the pair of guide posts are also provided with adjustment scale lines.

[0015] Furthermore, the guide rod also extends through a guide support seat set on the workbench surface. Beneficial effects

[0016] 1. This utility model transforms the traditional gear and rack drive into a servo drive motor driving a pulley assembly. The pulley assembly drives the connecting rod on it to move up and down, thereby realizing the up and down movement of the entire horizontal drive component and the bottle cap screwing gripper set on it, achieving the positioning and screwing operation. The height can be precisely controlled by the first drive motor.

[0017] 2. In this invention, the lateral drive component is also configured as a lead screw guide driven by a second drive motor. This allows for smoother left-right movement of the first connecting plate and its cap-screwing gripper and bottle-stabilizing gripper. Furthermore, the component moves back and forth along the bottle conveyor line at the same speed as the conveyor line, ensuring that the stability of the bottle on the conveyor line is not affected during capping.

[0018] 3. In this invention, the first connecting plate is slidably mounted on the second connecting plate via a first slide rail. Thus, during the vertical movement of the entire transverse drive component driven by the longitudinal drive component, the bottle-stabilizing grippers do not move vertically with the first connecting plate. Each pair of bottle-stabilizing grippers is driven by a gripper cylinder to clamp and release the bottle. Releasing the bottle does not affect its movement on the conveyor line. Therefore, the bottle-stabilizing grippers do not need to move vertically constantly. However, to ensure the bottle-stabilizing grippers can move horizontally with the transverse drive component, the first slide rail is designed. When the first connecting plate moves vertically, the first slider slides on the first slide rail, while the second connecting plate remains stationary, so the bottle-stabilizing grippers remain stationary. To maintain the stability of the bottle-stabilizing grippers' horizontal movement, a second slide rail is provided below the second connecting plate. During the horizontal movement driven by the transverse drive component, the first connecting plate drives the first slider and the second connecting plate to slide horizontally on the second slide rail, thus allowing them to slide horizontally with the transverse drive component while ensuring they do not move vertically with it.

[0019] 4. When capping bottles of different heights is required, this utility model incorporates a height-adjustable component on the bottle-stabilizing gripper. This allows for fine-tuning of the gripper's height manually, better meeting actual production needs. Manual adjustment involves rotating the handwheel, which drives the lead screw to move up and down relative to the fixed block. This movement of the lead screw, in turn, moves the third connecting plate up and down, thus controlling the overall movement of the gripper cylinder.

[0020] 5. This utility model has guide posts on both sides of the fixing block to play a guiding role, and scale lines are set on the guide posts. According to the bottle body of different heights, relevant marks can be made on the scale lines for convenient and precise adjustment. Attached Figure Description

[0031] Bottle stabilizing gripper 1 and bottle cap screwing gripper 2 are mounted on a transverse drive component 5, which is mounted on a longitudinal drive component 6. The transverse drive component 5 is mounted on a pair of vertically extending guide rods 601 that penetrate the worktable.

[0032] In this embodiment, the transverse drive component 5 is set as a lead screw guide rail, which is driven by the second drive motor 501.

[0033] At least one set of bottle stabilizing grippers 1 and bottle cap screwing grippers 2 are connected to the transverse drive member 5 via the first connecting plate 502. The transverse drive member 5 drives the first connecting plate 502 and the bottle stabilizing grippers 1 and bottle cap screwing grippers 2 on it to move back and forth along the transmission direction of the bottle conveyor line and the transmission speed is the same as the transmission speed of the bottle conveyor line.

[0034] A second connecting plate 503 is vertically arranged on one side of the first connecting plate 502. A first slide rail 504 is vertically arranged on one side of the second connecting plate 503. The first connecting plate 502 is slidably connected to the first slide rail 504 via a first slider 505. The bottle stabilizing gripper 1 is arranged on the other side of the second connecting plate 503. The lower end of the second connecting plate 503 is also slidably connected to the second slide rail 507 via a second slider 506. The sliding extension direction of the second slide rail 507 is consistent with the sliding extension direction of the transverse driving member 5.

[0035] In this embodiment, two bottle-stabilizing grippers 1 are connected to the first connecting plate 502, and bottle cap screwing grippers 2 are provided on the second connecting plate 503 in pairs with the bottle-stabilizing grippers 1.

[0036] The second connecting plate 503 is also equipped with a height adjustment component 7 for adjusting the height of the bottle body stabilizing gripper 1.

[0037] The height adjustment component 7 includes a fixing block 702 fixed on the second connecting plate 503, a lead screw 703 threaded through the fixing block 702, and the end of the lead screw 703 is rotatably connected to the third connecting plate 701 located below the fixing block 702 via a bearing.

[0039] Working principle:

[0040] First, adjust the height of the bottle stabilizing gripper 1 using the handwheel 705 according to the required bottle height for capping. After adjustment, start the operation. Place the bottle on the bottle conveyor line for transmission. When the bottle is transmitted to below the cap screwing gripper, the first drive motor 602 starts working, driving the entire horizontal drive component 5 and the first connecting plate 502 to move the cap screwing gripper 2 downward to a fixed height. At the same time, the second drive motor 501 starts working, driving the first connecting plate 502, the second connecting plate 503, the bottle stabilizing gripper, and the cap screwing gripper 2 to move to one side along the bottle conveyor line. During the movement, the gripper cylinder 3 and the rotary motor 4 work simultaneously. The gripper cylinder 3 controls the bottle stabilizing gripper 1 to hold the bottle, and the rotary motor 4 controls the cap screwing gripper 2 to screw the cap onto the bottle. After the screwing operation is completed, the first drive motor 602 drives the entire horizontal drive component 5 and the first connecting plate 502 to move the bottle cap screwing gripper 2 on it upward. At the same time, the second drive motor 501 reverses, driving the first connecting plate 502 to move the bottle cap screwing gripper 2 on it back to the initial position to continue the next round of screwing operation.
