With the continuous improvement of production efficiency and the development of automation technology, the traditional manual capping method can no longer meet the requirements of large-scale and high-efficiency production. Automatic capping equipment has gradually developed and improved in this context. It can quickly and accurately complete the capping operation of various containers, greatly improving production efficiency and reducing labor costs and human errors. Whether in the food, beverage, medicine or chemical industry, automatic capping equipment has become one of the key equipment to ensure product packaging quality and production progress. The emergence and development of automatic capping equipment has promoted the transformation and upgrading of the production model of related industries, creating higher economic benefits and competitive advantages for enterprises.

[0003] At present, the capping chuck of the automatic capping equipment is driven back and forth by the servo motor to drive the lead screw in the forward and reverse directions. The extension distance and retraction distance in each capping action are controlled by the servo motor, which has high requirements for accuracy and is prone to deviation.

However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below. Example 1

[0035] In this embodiment of the present application, refer to Figure 1-Figure 4 As shown, a reciprocating drive mechanism of an automatic capping device is provided, including a capping device power output shaft 1, a capping device push-pull rod 6 and a capping device chuck assembly 7, the capping device power output shaft 1 is connected to the capping device chuck assembly 7 through the capping device push-pull rod 6, the capping device power output shaft 1 is driven by a motor, and also includes:

[0036] A sliding arm 5, the sliding arm 5 is fixedly connected to a push-pull rod 6 of a capping device;

[0037] And it includes a track cam 4, which is fixedly connected to the power output shaft 1 of the capping device through a rotating drum 3. A track adapted to the sliding arm 5 is provided on the track cam 4, and the track and the track cam 4 are slidably matched. The track is distributed in a ring shape with the axis of the push-pull rod 6 of the capping device as the midpoint, and the height of the track from one end to the other end is a gradually changing high and low structure; each point of the track is the same distance from the axis of the push-pull rod 6 of the capping device. With the rotation of the track cam 4, the sliding arm 5 can be driven to slide along its track in a gradually changing height, thereby achieving the purpose of reciprocatingly driving the push-pull rod 6 of the capping device. With each rotation, a uniform extension distance is automatically achieved, thereby eliminating the need to use a servo motor and a lead screw to accurately control the travel length of the push-pull rod 6 of the capping device.

[0038] Tracks are provided on both the upper and lower sides of the track cam 4;

[0039] The push-pull rod 6 of the capping device is provided with two sliding arms 5 adapted to the tracks on the upper and lower sides of the track cam 4. The two sliding arms 5 can more stably withstand the force of the track cam 4, and the pushing and pulling is more stable. Example 2

[0040] This second embodiment is a further improvement on the first embodiment. Figure 1-Figure 4As shown, in order to have a greater transmission force, at least two track cams 4 are provided, and a plurality of sliding arms 5 adapted to the two track cams 4 are provided on the push-pull rod 6 of the capping device; the plurality of track cams 4 cooperate with the plurality of sliding arms 5 to have a greater transmission force, so that the push-pull action of the push-pull rod 6 of the capping device is more stable.

[0041] The highest points of the tracks on the two track cams 4 are located at symmetrical positions on both sides of the push-pull rod 6 of the capping device, and the sliding arms 5 that slide together on the two track cams 4 are located at symmetrical positions on both sides of the push-pull rod 6 of the capping device; the sliding arms 5 can transmit the force from the symmetrical positions on both sides of the push-pull rod 6 of the capping device, which is more stable compared to unilateral force.

[0042] The track on the track cam 4 includes a lifting section 41 and a horizontal section 42. The horizontal section 42 is located at the lowest point of the track on the track cam 4. When the push-pull rod 6 of the capping device is extended to the limit, the clamp assembly 7 of the capping device can just clamp and press the metal cover body. The function of the horizontal section 42 is to prevent the push-pull rod 6 of the capping device from retracting immediately, but to maintain a short clamping time to make the capping effect more stable. Example

[0043] This embodiment 3 is a further improvement on the basis of the embodiment 1. Figure 1-Figure 4 As shown, in order to make the movement of the sliding arm 5 and the power output shaft 1 of the capping device more stable, the track on the track cam 4 is a groove structure; a ball seat 51 is provided on the sliding arm 5, and a ball 52 is provided on the ball seat 51, and the ball 52 rolls with the track on the track cam 4; the ball 52 is connected by rolling on the track, so that the movable connection between the sliding arm 5 and the track cam 4 is smoother.

[0046] Working principle: When working, the power output shaft 1 of the capping device drives the rotating drum 3 to rotate, and the rotating drum 3 drives the track cam 4. As the track cam 4 rotates, it can drive the sliding arm 5 to slide along its track in a gradual up and down manner. Since the sliding arm 5 is fixedly connected to the push-pull rod 6 of the capping device, it can drive the push-pull rod 6 of the capping device to move synchronously, so as to achieve the purpose of reciprocatingly driving the push-pull rod 6 of the capping device. Figure 1-Figure 4 As shown in , every time the track cam 4 rotates one circle, its highest point, i.e., the retraction limit of the push-pull rod 6 of the capping device, and its lowest point, i.e., the extension limit of the push-pull rod 6 of the capping device, automatically reaches a uniform telescopic distance, thereby eliminating the need to use a servo motor and a lead screw to accurately control the travel length of the push-pull rod 6 of the capping device.
