Description

TECHNICAL FIELD

[0001] The application belongs to the field of syringe production equipment, and particularly relates to a crimping flattening device for syringe blister packaging. BACKGROUND

[0002] In the field of medical devices, a syringe is a very common instrument. The crimping of the syringe plays a key role in supporting the force when injecting liquid medicine, and the size is obviously larger than that of the needle cylinder. Considering the convenience of operation of medical staff, the crimping is usually designed into a long rhombus or a long ellipse, which makes the long axis and the short axis of the crimping have a large difference.

[0003] This special design requires that, when designing the blister packaging, the possibility of the long axis of the crimping in different directions must be fully considered, which undoubtedly leads to the fact that the syringes are often in a loose state in the blister packaging bag. Although the longer the long axis of the crimping is, the more convenient the operation of medical staff is, correspondingly, the packaging difficulty is also greatly increased. If the size of the blister is reduced when designing the blister packaging, the blister is easy to be broken by the crimping when the packaging heat sealing operation is performed, and then the sterile barrier function of the packaging bag is lost, which cannot meet the strict requirements of medical products on packaging sterility.

[0004] At present, in the common syringe packaging process on the market, the products in the packaging are generally irregular and loose, which not only seriously affects the appearance of the products, makes the products face the doubt of consumers on the quality of the products in the market sales, but also brings many inconveniences to medical staff in clinical use, greatly reduces the clinical use experience, and is not conducive to the efficient development of medical work.

DETAILED DESCRIPTION

[0028] The best embodiment of the crimp flattening device for blister packaging of syringes is shown in the accompanying drawings, and the present application will be further described in detail below in conjunction with the drawings.

[0029] As shown by Figure 1 and Figure 2 , a crimp flattening device for blister packaging of syringes includes a flattening screw rod 13 as the main component, which uses the clamping groove on its circumferential surface to flatten the crimp of the packaging product, so that the crimp of the packaging product is in a horizontal state, achieving consistency in packaging.

[0030] The flattening screw rod 13 is rotatably connected to the screw rod fixing side plates 9 at both ends, and rolling bearings 18 are arranged at the rotating holes, which are sleeved on the middle shaft of the flattening screw rod 13. The screw rod fixing top plate 5 is fixedly connected above the two screw rod fixing side plates 9, the servo motor 10 is fixed on the screw rod fixing side plate 9, and the output shaft of the servo motor 10 is connected with the flattening screw rod 13.

[0031] Further, the servo motor 10 is fixedly connected with the screw rod fixing side plate 9 through the motor fixing plate 12 and the motor support plate 19, and the output shaft of the servo motor 10 is connected with the flattening screw rod 13 through the coupling 11.

[0032] The flattening screw rod 13, the screw rod fixing side plate 9, the screw rod fixing top plate 5, the servo motor 10, etc. form an independent module unit, which is convenient for overall replacement and maintenance in the later stage.

[0033] The crimp flattening device for the syringe blister package also comprises a support plate 4, which is designed as an I-shaped type in order to reduce the weight while ensuring the strength. A support rod 1 is arranged at each of the four corners of the lower part of the support plate 4. The top part of the support rod 1 is threaded, and a height adjusting nut 2 and a cover nut 3 are threadedly connected to the threaded part. The height adjusting nut 2 is used to adjust the height position and the mechanism level of the device, and the cover nut 3 is used to block the threads at the end of the support rod. The support plate is fixed at a certain height on the support rod by the height adjusting nut and the cover nut, so that the outer circle of the flattening screw rod 13 is tangent to the short shaft of the syringe crimp. The threaded part at the top of the support rod 1 is threadedly connected to the threaded hole on the support plate 4.

[0034] The bottom part of the support plate 4 is provided with a vertically arranged slide rail fixing frame 6, and the slide rail fixing frame 6 is provided with a slide rail 7. A sliding block 8 on the slide rail 7 is fixedly connected to a screw rod fixing side plate 9.

[0035] A vertically arranged balance shaft 14 is slidably arranged on the support plate 4, and the bottom part of the balance shaft 14 is fixedly connected to the screw rod fixing top plate 5. A support spring 16 is sleeved on the balance shaft 14, and the upper and lower ends of the support spring 16 are respectively abutted against the support plate 4 and the screw rod fixing top plate 5. A clamping spring 17 is clamped on the top part of the balance shaft 14, so as to prevent the balance shaft 14 from being disengaged.

[0036] The support plate 4 is provided with a through hole, and a linear bearing 15 is arranged in the through hole. The balance shaft 14 is inserted into the linear bearing 15.

[0037] When the syringe crimp is not in a horizontal state, it will be lifted by the crimp long shaft support motor output mechanism after colliding with the flattening screw rod 13. The two support springs 16 will be compressed. With the rotation of the flattening screw rod 13 and the spring elastic force, the crimp is flattened by the clamping groove of the flattening screw rod 13. Thus, the crimps of the products to be packaged are in a horizontal state, and the consistency of the packaging is achieved.

[0038] The installation position of the crimp flattening device for the syringe blister package on the packaging machine is shown in Figure 3 , and the installation position of the crimp flattening device for the syringe blister package on the packaging machine is shown in

[0039] The embodiments of the present application are described in detail above in combination with the drawings, but the present application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the purpose of the present application.
