Description

Technical Field

[0001] This utility model relates to the field of capping device technology, specifically a capping device for the production of pharmaceutical polyester bottles. Background Technology

[0002] Polyester is a general term for thermoplastic saturated polyesters, represented by PET, including PBT, PEN, PCT, and their copolymers. Among them, PET is the earliest developed, has the largest production volume, and is the most widely used polyester product. In the packaging field, the development of polyester in packaging containers is particularly noteworthy. Currently, more than 20% of PET is used in packaging materials, and this trend is increasing year by year. Polyester bottles are mostly used to store liquid medicines, and sealing the polyester bottle cap is an essential step in the production and processing of polyester bottles.

[0003] Existing capping devices can only cap a single bottle at a time, reducing production efficiency. Furthermore, the capping is driven by a single motor, making it difficult to precisely control the force. This results in either insufficient tightening, leading to leakage of the medicine, or excessive tightening, damaging the bottle or cap. Polyester bottles are also prone to shifting on the conveyor, causing misalignment between the cap and the bottle body during capping and increasing the defect rate. To address these issues, we propose a capping device for the production of pharmaceutical polyester bottles. Utility Model Content

[0004] The purpose of this invention is to provide a capping device for the production of pharmaceutical polyester bottles, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a screw capping device for producing pharmaceutical polyester bottles, comprising a base, a conveyor and limiting strips, wherein the conveyor is installed inside the base, limiting strips are installed on both sides of the outer wall of the conveyor, a connecting frame is installed at the middle position above the base, and a processing structure is installed inside the connecting frame;

[0006] The processing structure includes a fixing plate, positioning grooves, and protective pads. Fixing plates are located on both sides inside the connecting frame. Multiple positioning grooves are located on the inner side of the fixing plates, and protective pads are installed on the inner walls of the positioning grooves. First electric cylinders are installed on both sides of the outer wall of the fixing plates, and the outer walls of the first electric cylinders are connected to the inner wall of the connecting frame. A fixing frame is located above the first electric cylinders. Second electric cylinders are installed on both sides of the outer wall of the fixing frame, and the outer walls of the second electric cylinders are connected to the inner wall of the connecting frame. Multiple first fixing posts are located on the inner side of the fixing frame. Gears are installed on the upper part of the outer wall of each first fixing post, and chains are installed on the outer sides of the multiple gears. Second fixing posts are installed below the outer walls of the first fixing posts, and rubber pads are installed on the outer walls of the second fixing posts. The two sides of the multiple first fixing posts on the left are connected to the inner wall of the fixing frame via first bearings. The lower part of one first fixing post on the right is connected to the inner wall of the fixing frame via a second bearing. The upper part of the one first fixing post on the right passes through the fixing frame and connects to the output end of the motor.

[0007] Preferably, the transport machine and the limiting strip are fixedly connected, and the base and the connecting frame are fixedly connected.

[0008] Preferably, the fixing plate and the positioning groove are integrated, and the positioning groove and the protective pad are tightly fitted together.

[0009] Preferably, the fixing plate and the first electric cylinder are arranged perpendicular to each other.

[0010] Preferably, the fixing frame is U-shaped, and the first fixing post is fixedly connected to the gear and the second fixing post.

[0011] Preferably, the second fixing post and the rubber pad are tightly fitted together, and the outer wall of the rubber pad is provided with a protrusion.

[0012] Preferably, the fixing frame and the second electric cylinder are arranged perpendicular to each other.

[0013] Preferably, the first fixed post on the left side is rotatably connected to the first bearing, and the first fixed post on the right side is rotatably connected to the second bearing.

[0014] Preferably, the first fixed post on the right side is fixedly connected to the output end of the motor.

[0015] Preferably, the midpoint between the limiting strips on both sides, the midpoint between the fixing plates on both sides, and the midpoint between the fixing brackets on both sides are on the same horizontal line.

[0016] Compared with existing technologies, the beneficial effects of this utility model are:

[0017] By setting up a fixing plate, positioning groove and protective pad, the user places multiple polyester bottles with caps in the middle position between two limit bars, starts the conveyor to move the polyester bottle bodies between the fixing plates, starts the first electric cylinder to drive the fixing plate to move inward, so that the polyester bottle bodies enter the positioning groove and are clamped and fixed, ensuring the precise position of the bottle before screwing on the cap, improving the quality of screwing on the cap, and the protective pad is tightly attached to the inner wall of the positioning groove to protect the outer wall of the bottle from damage.

[0018] Secondly, the second electric cylinder is activated, causing the fixing frame to move inward, so that the rubber pad on the first fixing post contacts the bottle cap on top of the bottle. The rubber pad increases the friction between the rubber pad and the bottle cap, ensuring that the bottle cap will not slip during the tightening process. Finally, the motor is started, and the chain transmission system drives one of the first fixing posts on the right to rotate inside the second bearing. Through the meshing of the gears and the chain, the other first fixing posts are driven to rotate synchronously. The second fixing posts and rubber pads connected to the first fixing posts rotate accordingly, thereby realizing the tightening operation of the bottle cap on top of the bottle. Throughout the process, manual intervention is reduced, and the bottle caps on multiple bottles can be tightened simultaneously, improving production efficiency. Attached Figure Description

[0039] Working principle:

[0040] First, the user places multiple polyester bottle bodies 6 with caps in the middle position between two limit bars 3, starts the conveyor 2, and moves the polyester bottle bodies 6 between the fixed plates 501.

[0041] Secondly, the second electric cylinder 506 is activated, causing the fixing frame 505 to move inward, so that the rubber pad 510 on the first fixing post 507 contacts the bottle cap on top of the bottle. The rubber pad 510 increases the friction between the bottle cap and the cap, ensuring that the cap will not slip during the tightening process. Finally, the motor 513 is activated, which drives one of the first fixing posts 507 on the right side to rotate inside the second bearing 512 through the chain transmission system. Through the meshing of the gear 508 and the chain, the other first fixing posts 507 are driven to rotate synchronously. The second fixing post 509 and the rubber pad 510 connected to the first fixing post 507 rotate accordingly, thereby realizing the tightening operation of the bottle cap on top of the bottle. Throughout the process, manual intervention is reduced, and the bottle caps on multiple bottles can be tightened simultaneously, improving production efficiency.
