[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In the preferred embodiment of the capping device for the production of bupivacaine hydrochloride injection, the fixing part is composed of a fixing rod and a fixing ring 8. The fixing rod is fixedly mounted on the top of the rotating motor 5 and the cylinder 2 6 through a threaded structure to ensure the stability of the structure and the convenience of adjustment. The fixing ring 8 is respectively connected to the output ends of the fixing rod, the lifting motor 4 and the rotating motor 5 through a threaded structure. This design makes it easy to disassemble and assemble the above-mentioned components.

[0025] In the preferred embodiment of the capping device for the production of bupivacaine hydrochloride injection, at least three air holes are provided on the side of the cylinder 2 6, and at least three clamping rings 7 are matched thereto. The design of multiple holes and multiple clamping rings 7 can increase the stability and efficiency of the capping process.

[0026] In the preferred embodiment of the capping device for the production of bupivacaine hydrochloride injection, a slide groove is provided at the bottom of the cylinder, and the top of the clamping ring 7 is slidably connected to the slide groove through a slide rod 9. This design enables the clamping ring 7 to move smoothly under the drive of the cylinder to achieve precise capping action. Both the slide rod 9 and the slide groove are T-shaped structures, and this design enhances the stability and anti-falling ability of the slide rod 9 in the slide groove.

[0027] In the preferred embodiment of the capping device for the production of bupivacaine hydrochloride injection, the inner sides of the limiting rod 2 and the clamping ring 7 include rubber pads, and the inner sides of the rubber pads are also provided with a plurality of anti-slip grooves. These designs increase the friction between the capping device and the object to be capped, thereby preventing the object from slipping or being damaged during the capping process.

[0028] In the preferred embodiment of the capping device for the production of bupivacaine hydrochloride injection, a push rod 11 is provided at the bottom of the cylinder 6, and the push rod 11 is located at the center of the cylinder 6.

[0029] The clamp of the capping device for the production of bupivacaine hydrochloride injection mainly consists of two groups of cylinders 1, which are symmetrically installed to ensure balanced force. A limit rod 2 is fixedly installed at the output end of each cylinder 1, and the limit rod 2 is used to position and fix the object to be capped during the capping process. The capping assembly mainly includes a frame 3, a lifting motor 4, a rotating motor 5 and a clamping device. The frame 3 serves as the basic structure of the entire capping assembly and provides stable support. The lifting motor 4 is fixedly installed on the top of the frame 3, and the lifting movement of the clamping device in the vertical direction is realized through its power output. The top of the rotating motor 5 is connected to the output end of the lifting motor 4 through a fixing piece, so that the rotating motor 5 can be lifted and lowered together with the lifting motor 4, and the rotating motor 5 itself can drive the clamping device below it to rotate. The clamping device is installed at the output end of the rotating motor 5 through a fixing piece, and it is responsible for clamping the object to be capped and completing the capping action under the drive of the rotating motor 5. The working principle of the utility model is the following steps:

[0030] 1. The object to be capped is first placed between the limit rods 2 of the clamp, and the limit rods 2 are driven by the cylinder 1 to fix them;

[0031] 2. The lifting motor 4 is started, driving the rotating motor 5 and the clamping device to descend to a suitable position, so that the clamping ring 7 can clamp the object to be capped;

[0032] 3. The air cylinder 2 6 drives the clamping ring 7 through the air hole and the air rod 10 to perform a clamping action to firmly fix the object to be capped;

[0033] 4. The rotating motor 5 is started, driving the clamping device and the article to be capped to rotate to the capping position;

[0034] 5. While rotating, the capping assembly completes the capping action, for example, by fixing the capping material on the object to be capped by heat sealing, pressure sealing, etc.;

[0035] 6. After the capping is completed, the rotating motor 5 and the lifting motor 4 work in reverse to lift the clamping device and the capped objects to the initial position, and then the cylinder 1 and the cylinder 2 6 release the objects to be capped, completing the entire capping process.
