Problems solved by technology

[0004] But at present, when applying glue on the cover and the cylinder, the glue is generally directly applied between the cover and the cylinder, but because the cylinder is in the shape of a ring, the positioning of the cylinder and the cover is difficult, which may easily lead to The positioning of the cap and the barrel is not accurate, which leads to a decrease in the molding quality of the bottle

Embodiment 1

[0055] Embodiment one: refer to figure 2 and image 3, a production process of a plastic cylindrical drug storage tank adopts the following technical scheme:

[0056] S1, forming of barrel 1:

[0057] 1. Form the cylinder 1 according to the size of the cylinder 1 to be processed;

[0058] 2. Form ring grooves 11 with the same diameter as the cylinder body 1 on both ends of the cylinder body 1;

[0059] 3. Open a glue injection port 12 connected to the ring groove 11 at the end of the cylinder 1;

[0060] 4. Open a plurality of through holes 13 connected to the ring groove 11 at the end of the outer peripheral surface of the cylinder body 1, and the plurality of through holes 13 are uniformly arranged around the axis of the cylinder body 1;

[0061] 5. A bevel 1 is provided on the outer peripheral surface of the end of the cylinder body 1;

[0062] S2: Forming of end cap 2:

[0063] 1. Form the two end caps 2 according to the size of the end cap 2 to be processed, and op...

Embodiment 2

[0080] Embodiment two: refer to Figure 4 , compared with Embodiment 1, the difference lies in:

[0081] S3, connector forming:

[0082] 1. The positioning ring 31 is formed according to the dimensions of the first ring groove 11 and the second ring groove 22. The width of the positioning ring 31 is equal to the sum of the depths of the first ring groove 11 and the second ring groove 22. The inner diameter of the positioning ring 31 is the same as the inner diameter of the first ring groove 11. Same, the outer diameter of the positioning ring 31 is smaller than the outer diameter of the ring groove-11;

[0083] 2. A plurality of through grooves 311 are provided on the peripheral surface of the positioning ring 31, and the plurality of through grooves 311 are all rectangular grooves in the same direction as the axis of the positioning ring 31, and the plurality of rectangular grooves are evenly distributed around the axis of the positioning ring 31 On the peripheral surface o...

Abstract

The invention relates to the field of medicine storage tank production, in particular to a production process of a plastic cylindrical medicine storage tank. The process comprises the following stepsof S1, forming a cylinder; S2, forming an end cover; S3, forming a connecting piece; S4, splicing the medicine storage tank; and S5, gluing the medicine storage tank. According to the production process, splicing positioning of the cylinder and a sealing cover can be ensured, and the effect of ensuring the forming quality of the medicine storage tank is achieved.

Description

technical field [0001] The present application relates to the field of medicine storage tank production, in particular to a production process of a plastic cylindrical medicine storage tank. Background technique [0002] A medicine storage tank is a tank used to store medicines. Depending on the type of medicines to be stored, there are different requirements for the tank. However, generally medicine storage tanks need to have higher strength and higher airtightness. [0003] Currently there is a plastic storage tank such as figure 1 Shown: including the cylinder body, both ends of the cylinder body are provided with caps, and any cap is provided with a filling port. During use, the medicinal liquid can be directly injected into the medicine storage tank through the filling port for storage, and then used to block and close the filling port. At present, in the production process of this kind of plastic medicine storage tank, the cover and the cylinder are generally sealed ...
