[0002] On packaging production lines in industries such as food, pharmaceuticals, and chemicals, capping machines are one of the key pieces of equipment for sealing containers (such as glass bottles and plastic bottles). Their working principle is usually to transport the container to the capping station through a transmission mechanism, and then the capping mechanism tightens the cap.

[0003] Announcement No. CN222907508U discloses a capping machine with positioning function, including a capping machine body. A capping device is mounted on one side of the capping machine body. One end of a first hydraulic push rod is mounted at each of the four bottom corners of the capping machine body, and a support base is mounted on the other end of the first hydraulic push rod. A limiting component is provided on one side of the capping device. A conveying component is mounted on one side of the capping machine body. The limiting component includes a second hydraulic push rod mounted on one side of the capping machine body, and a support platform is mounted on one end of the second hydraulic push rod. This improved capping machine uses a limiting component design, which can effectively clamp the item and prevent displacement during the capping process. It also features a convenient conveying design, facilitating the delivery of the item to the area directly below the capping device for subsequent clamping, effectively improving the production efficiency of the capping machine. However, the positioning method of this technical solution mainly relies on two arc-shaped clamping plates to position and clamp the bottle. The size and curvature of these clamping plates are fixed and cannot adapt to various container sizes, resulting in relatively poor flexibility in use. Utility Model Content

[0004] The purpose of this invention is to provide a capping machine with positioning function, which solves the problem that the existing positioning method mainly uses two arc-shaped clamping plates to position and clamp the bottle.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 As shown, this utility model is a capping machine with positioning function, including a base 1, a transmission mechanism 2, a capping mechanism 4, and a mechanical gripper 5. A mounting frame 3 is fixedly installed on the upper surface of the base 1, and the capping mechanism 4 is installed on the inner wall of the mounting frame 3. The clamping end of the mechanical gripper 5 is located on one side of the material feeding end of the base 1 and the material conveying end of the transmission mechanism 2. An installation cavity 101 is opened inside the base 1, and three sliding grooves 102 are opened on the upper surface of the base 1. All sliding grooves 102 are connected to the inside of the installation cavity 101. A positioning mechanism is installed inside the installation cavity 101, and the positioning end of the positioning mechanism is slidably connected inside the sliding groove 102.

[0018] The positioning mechanism includes a motor 601, which is fixedly installed at the bottom of the mounting cavity 101. A lead screw 602 is fixedly installed at the output end of the motor 601. A threaded sleeve 603 is sleeved on the outer surface of the lead screw 602. Three connecting shells 604 are fixedly installed on the circumferential side of the threaded sleeve 603. A connecting rod 605 is rotatably connected inside each connecting shell 604. The interior of each slide 102 is slidably connected to a movable plate 606, and one end of each of the three movable plates 606 is rotatably connected to one end of the connecting rod 605. A clamping plate 607 is fixedly installed at the other end of the movable plate 606, and a rubber pad 608 is fixedly installed on one side of the clamping plate 607. The bottle to be capped is placed at the designated position on the upper surface of the base 1. The motor 601 of the positioning mechanism is started, driving the lead screw 602 to rotate. The threaded sleeve 603 moves linearly along the lead screw 602, causing the three connecting shells 604 fixed on its circumferential side to move synchronously. The connecting rod 605 in each connecting shell 604 moves accordingly, and pulls the movable plate 606 connected to its other end to slide in the corresponding slide groove 102. The three movable plates 606 drive the clamping plates 607 and rubber pads 608 at their ends to move towards the center along the slide groove 102 at the same time, clamping the container evenly from three directions, completing automatic centering and positioning, ensuring that the container axis is aligned with the capping mechanism 4. Then, the capping mechanism 4 screws the bottle cap onto the bottle. Next, the mechanical gripper 5 clamps the bottle onto the transmission mechanism 2, and the transmission mechanism 2 transports the bottle to the next process.

[0019] An air supply pipe connection pipe 7 is fixedly installed on one side of the base 1, and the air supply pipe connection pipe 7 is connected to the interior of the mounting cavity 101; A dust discharge port 8 is provided on the other side of the base 1, and the dust discharge port 8 is connected to the interior of the mounting cavity 101; Through the air supply pipe connection pipe 7 and dust discharge port 8, airflow can be introduced into the installation cavity 101 to blow away any dust, debris or spilled liquid that may enter. This function helps to keep the moving parts of the positioning mechanism clean, reduce wear and jamming, extend the service life of the equipment, and maintain the cleanliness of the working environment.

[0020] Working principle: In use, the bottle to be capped is placed at the designated position on the upper surface of the base 1. The motor 601 of the positioning mechanism starts, driving the lead screw 602 to rotate. The threaded sleeve 603 moves linearly along the lead screw 602, causing the three connecting shells 604 fixed on its circumferential side to move synchronously. The connecting rod 605 in each connecting shell 604 moves accordingly, pulling the movable plate 606 rotatably connected to its other end to slide in the corresponding slide groove 102. The three movable plates 606 drive the clamping plates 607 and rubber pads 608 at their ends to move simultaneously towards the center along the slide groove 102, clamping the container evenly from three directions. The automatic centering and positioning are completed to ensure that the container axis is aligned with the capping mechanism 4. Then, the capping mechanism 4 tightens the cap onto the bottle. Next, the mechanical gripper 5 picks up the bottle and places it onto the transfer mechanism 2. The transfer mechanism 2 then transports the bottle to the next process. Through the set air supply pipe connection pipe 7 and dust exhaust port 8, airflow can be introduced into the installation cavity 101 to blow away any dust, debris, or spilled liquid that may have entered. This function helps to keep the moving parts of the positioning mechanism clean, reduce wear and jamming, extend the service life of the equipment, and maintain the cleanliness of the working environment.
