Description

Technical Field

[0001] This utility model relates to the field of capping machine technology, specifically a capping mechanism for a bottle cap capping machine. Background Technology

[0002] A capping machine is a machine used to install bottle caps during the filling process. It uses mechanical grippers to fix the bottle caps, and then a rotating mechanism drives the grippers to rotate, thereby fixing the bottle caps to the bottle body.

[0003] Existing capping machines typically require a moving mechanism to move the mechanical gripper to the feeding position to grab the material, and then return it to the capping position to cap it. This requires the entire capping mechanism to be equipped with an additional moving mechanism and a gripping and positioning mechanism, resulting in higher overall capping installation costs and greater positioning difficulty. Therefore, a capping mechanism for a bottle capping machine is provided to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a capping mechanism for a bottle capping machine, which solves the problem that existing capping mechanisms require additional moving mechanisms and gripping and positioning mechanisms, resulting in higher overall capping and installation costs and greater positioning difficulties.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a capping mechanism for a bottle cap screwing machine, comprising;

[0006] A feeding component, wherein the feeding component is used for continuous feeding of bottle caps;

[0007] The capping component includes;

[0008] Screw cap servo motor;

[0009] A rotary disk is rotatably mounted inside the feeding component and is fixedly connected to the output end of the capping servo motor.

[0011] The feeder has a capping station inside one end, and the rotary disk is rotatably set in the capping station. Multiple round-headed pins for supporting bottle caps are movably arranged on the bottom side wall of the capping station.

[0012] Preferably, the feeder includes;

[0013] The feed guide plate is integrally formed on one side of the capping station;

[0014] The feeding channel is located inside the feeding guide plate and is connected to the inside of the capping station.

[0015] Preferably, the top of the feeding channel away from the capping station is provided with a feeding port, and friction conveyor belts are installed on both sides of the inner wall of the feeding channel. The two sets of friction conveyor belts transfer the bottle cap from the feeding port to the capping station through friction on opposite sides.

[0016] Preferably, a cover plate is fixedly installed on the top of the capping station, and the capping servo motor is fixedly installed on the top of the cover plate.

[0017] Preferably, the bottom end of the capping station is provided with a feeding port, and a plurality of round-headed pins are arranged in a ring array in the side wall of the feeding port, and the inner end of the round-headed pins is provided with a spring.

[0018] Preferably, a connecting seat is fixedly provided on the top of the rotating disk, and conductive slip rings are respectively installed on the side of the connecting seat opposite to the cover plate, and the two sets of conductive slip rings are rotatably electrically connected.

[0019] Preferably, an electric telescopic rod is installed inside the rotating disk, the output end of the electric telescopic rod is fixedly connected to the cap clamping plate, and the electric telescopic rod is electrically connected to the conductive slip ring.

[0021] This utility model discloses a capping mechanism for a bottle capping machine, which has the following advantages: multiple bottle caps are placed sequentially at the feeding port. The bottle caps are then conveyed inward along the feeding channel by a friction conveyor belt, so that the bottle caps finally fall into the capping station. At this time, multiple rounded tops in the capping station support the bottle caps. The output end of the electric telescopic rod retracts, driving the capping clamping plate to move towards the center to clamp the bottle caps. The capping servo motor starts, and the capping clamping plate drives the bottle caps to rotate, so that they are installed on the bottle body. Then the capping clamping plate is released, and the bottle body and bottle cap move down synchronously and are removed from the capping station, completing the capping. This enables continuous and accurate feeding of bottle caps, making the capping operation more efficient, and reducing the control difficulty and cost. Attached Figure Description

[0029] This application provides a capping mechanism for a bottle capping machine, which solves the problem that existing capping mechanisms require additional moving mechanisms and gripping and positioning mechanisms, resulting in higher overall capping and installation costs and greater positioning difficulty.

[0030] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0031] This utility model discloses a capping mechanism for a bottle cap screwing machine.

[0032] Example 1

[0033] According to the appendix Figure 1-4 As shown, including;

[0034] Feeding component 1 is used for continuous feeding of bottle caps;

[0035] Screw cap 2, screw cap 2 includes;

[0036] Capping servo motor 21;

[0037] The rotary disk 22 is rotatably disposed inside the feed component 1 and is fixedly connected to the output end of the capping servo motor 21;

[0038] The capping clamping plate 23 is movably disposed on both sides of the rotating disk 22 for clamping the bottle cap. When the two sets of capping clamping plates 23 move to the sides and separate, the bottle cap can automatically slide down through the feeding channel 12 between the two sets of capping clamping plates 23 and be in the capping station 15. At this time, the capping clamping plate 23 moves towards the center and clamps the upper outer surface of the bottle cap.

[0039] The feed part 1 has a capping station 15 inside one end. The rotating disk 22 is rotatably set in the capping station 15. Multiple round-headed pins 17 for supporting bottle caps are movably set on the bottom side wall of the capping station 15.

[0040] A cover plate 16 is fixedly installed on the top of the capping station 15, and the capping servo motor 21 is fixedly installed on the top of the cover plate 16.

[0041] A connecting seat 26 is fixedly installed on the top of the rotating disk 22. A conductive slip ring 27 is installed on the side of the connecting seat 26 opposite to the cover plate 16. The two sets of conductive slip rings 27 are rotatably electrically connected. An electric telescopic rod 24 is installed inside the rotating disk 22. The output end of the electric telescopic rod 24 is fixedly connected to the cap clamping plate 23. The electric telescopic rod 24 is electrically connected to the conductive slip ring 27. The conductive slip ring 27 ensures that the electric telescopic rod 24 can always maintain electrical connection when it rotates with the output shaft of the cap servo motor 21.

[0042] A positioning rod 25 is fixedly installed on the inner side of the cap clamping plate 23, and the positioning rod 25 is movably inserted into the rotating disk 22.

[0043] Working principle: When the device is in use, the bottle cap enters the capping station 15 through the feeding part 1. At this time, the output end of the electric telescopic rod 24 retracts, driving the capping clamping plate 23 to move towards the center to clamp the bottle cap. At this time, the bottle body waiting to be capped moves from below into the capping station 15. Then, the capping servo motor 21 starts, driving the bottle cap to rotate through the capping clamping plate 23, so that it is installed on the bottle body. Then, the capping clamping plate 23 is released, and the bottle body and the bottle cap move down synchronously and are removed from the capping station 15, completing the capping.

[0044] Example 2

[0045] According to the appendix Figure 1-4 As shown, based on Embodiment 1, more specifically, the feeder 1 includes:

[0046] The feed guide plate 11 is integrally formed on one side of the capping station 15;

[0047] The feeding channel 12 is located inside the feeding guide plate 11 and is connected to the inside of the capping station 15.

[0048] The top of the feeding channel 12 away from the capping station 15 is provided with a feeding port 13. Friction conveyor belts 14 are installed on both sides of the inner wall of the feeding channel 12. The bottle caps are transferred from the feeding port 13 to the capping station 15 by friction on the opposite side of the two sets of friction conveyor belts 14.

[0049] The bottom end of the capping station 15 is provided with a feeding port, and multiple round-headed pins 17 are arranged in a ring array in the side wall of the feeding port, and a spring 18 is provided at the inner end of the round-headed pins 17.

[0050] Working principle: When the device is in use, multiple bottle caps are placed sequentially at the feeding port 13. At this time, the bottle caps are conveyed inward along the feeding channel 12 by the friction conveyor belt 14, so that the bottle caps finally fall into the capping station 15. At this time, multiple round-headed pins 17 in the capping station 15 support the bottle caps, preventing them from falling. After the capping is completed, as the bottle body moves downward, the bottle cap moves downward synchronously, causing the multiple round-headed pins 17 to be squeezed outward, which compresses the spring 18, allowing the bottle caps to be smoothly removed from the capping station 15. At the same time, after the bottle caps are removed, the spring 18 pushes the round-headed pins 17 to move back to the center to reset, providing support for the next set of bottle caps.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
