Description

Technical Field

[0001] The utility model relates to the technical field of biopharmaceuticals, in particular to the field of a silicone oil spraying device for siliconizing the inner wall of a cartridge bottle. Background Art

[0002] During the production process, the inner wall of the cartridge bottle must be siliconized, that is, a layer of silicone oil film is produced on the inner wall of the bottle, so that the sliding property between the rubber stopper and the inner wall of the bottle meets the requirements. The silicone oil used in the siliconization process is a foreign matter for the medicine, and the amount of silicone oil on the inner wall of the cartridge bottle directly affects the quality of the medicine. Therefore, when siliconizing the inner wall of the cartridge bottle, the amount of silicone oil should be reduced as much as possible while ensuring that the sliding property meets the requirements. In the prior art, some silicone oil spraying devices use peristaltic pumps to control the amount of silicone oil. Due to the high viscosity of silicone oil, the control accuracy of this method is low; some silicone oil spraying devices use time pressure valves to control the amount of silicone oil. This control system is more complex and external factors have a greater impact on the accuracy. In addition, when the equipment is suspended for a long time, since the silicone oil spraying device has no check structure, the silicone oil will flow back under the action of gravity. When the silicone oil spraying device is started again, the accuracy of the silicone oil amount is low.

[0003] Therefore, it is urgent to develop a silicone oil spraying device for siliconizing the inner wall of a cartridge bottle to effectively solve at least one of the above technical problems. Utility Model Content

[0035] A silicone oil spraying device for siliconizing the inner wall of a cartridge bottle of the present invention will be described in more detail below in conjunction with the accompanying drawings, wherein preferred embodiments of the present invention are shown. It should be understood that those skilled in the art can modify the present invention described herein while still achieving the advantageous effects of the present invention. Therefore, the following description should be understood as being widely known to those skilled in the art and not as a limitation to the present invention.

[0036] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0037] like Figure 1As shown, this embodiment proposes a silicone oil spraying device for siliconizing the inner wall of a cartridge bottle, comprising: a silicone oil storage tank 5; a front-pump oil delivery pipe 4, the input end of which is connected to the silicone oil storage tank 5; a plunger micro pump 3, the input end of which is connected to the output end of the front-pump oil delivery pipe 4; a rear-pump oil delivery pipe 2, the input end of which is connected to the output end of the plunger micro pump 3; and a silicone oil atomizing needle assembly 1, which is connected to the output end of the rear-pump oil delivery pipe 2.

[0038] The plunger micro pump 3 is mainly composed of a pump body and a plunger that can move back and forth inside the pump body. During the process of the plunger retreating (sucking oil), a negative pressure area will be formed inside the pump body, and this negative pressure area will attract silicone oil from the silicone oil storage tank 5 through the front oil delivery pipe 4 into the pump body. In this process, since the displacement of the plunger can be precisely controlled, the amount of silicone oil sucked can also be precisely controlled.

[0039] Then, during the process of the plunger moving forward (discharging oil), a positive pressure zone will be formed inside the pump body, and this positive pressure zone will push the silicone oil to flow through the rear oil delivery pipe 2 to the silicone oil atomizing needle assembly 1. Similarly, since the displacement of the plunger can be precisely controlled, the amount of silicone oil discharged can also be precisely controlled.

[0040] In this way, the plunger micro pump can achieve precise control of the amount of silicone oil delivered, thereby ensuring that the amount of silicone oil sprayed each time is accurate and the degree of siliconization of the inner wall of each cartridge is consistent.

[0041] like Figure 2 As shown, in this embodiment, the silicone oil atomizing spray needle assembly 1 includes: a silicone oil non-return component 11, connected to the output end of the rear oil delivery pipe 2 of the pump; an oil delivery inner pipe 12, the input end of which is connected to the silicone oil non-return component 11; a silicone oil atomizing spray needle seat 14, connected to the output end of the oil delivery inner pipe 12; an atomizing gas source connector 15, arranged on the silicone oil atomizing spray needle seat 14; and an air delivery outer pipe 17, connected to the silicone oil atomizing spray needle seat 14.

[0042] Preferably, the silicone oil atomizing spray needle assembly 1 further comprises: an oil delivery inner tube sealing gasket 13, which is arranged between the oil delivery inner tube 12 and the silicone oil atomizing spray needle seat 14. The main function of the oil delivery inner tube sealing gasket 13 is to prevent silicone oil from leaking during the delivery process.

[0043] Furthermore, the silicone oil atomizing needle assembly 1 further comprises: an air delivery outer pipe sealing gasket 16, which is arranged between the air delivery outer pipe 17 and the silicone oil atomizing needle seat 14. The main function of the air delivery outer pipe sealing gasket 16 is to prevent leakage of compressed air during the delivery process.

[0044] In a specific example, the silicone oil non-return component 11 includes: a silicone oil tube fixing head 111, connected to the output end of the rear oil delivery pipe 2 of the pump; a non-return component seat 112, connected to the silicone oil tube fixing head 111; a non-return cone hole 113, arranged on the output end of the rear oil delivery pipe 2 of the pump; and a non-return steel ball 114, arranged on the non-return cone hole 113.

[0045] Furthermore, the silicone oil non-return component 11 further includes: a non-return component sealing gasket 115, which is arranged at the input end of the oil delivery inner tube 12 to prevent the silicone oil from flowing back during the spraying process.

[0046] The purpose of providing the silicone oil non-return component 11 in the silicone oil atomizing needle assembly 1 is that, during the process of siliconizing the inner wall of the cartridge bottle, the device is to place the mouth of the cartridge bottle downward and be vertical to the nozzle of the silicone oil atomizing needle assembly 1. When the work is suspended, the non-return steel ball 114 is tightly attached to the non-return cone hole 113 under the action of gravity and blocks the non-return cone hole 113, thereby preventing the silicone oil from flowing back.

[0047] Furthermore, the silicone oil atomizing needle seat 14 is provided with an air delivery hole 141 .

[0048] Furthermore, the atomizing gas source connector 15 is installed on the silicone oil atomizing needle seat 14 and communicates with the gas delivery hole 141. Silicone oil atomization is achieved through the atomizing gas source connector 15 and the gas delivery hole 141. When compressed air enters from the atomizing gas source connector 15, passes through the gas delivery hole 141, and enters the gas delivery outer tube 17, the compressed air is accelerated under the action of the gas distributor 121 and reaches the outlet of the gas delivery outer tube 17. This high-speed compressed air will break up the silicone oil flowing through the oil delivery inner tube 12 to form tiny silicone oil droplets, thereby achieving uniform atomization of the silicone oil.

[0049] Furthermore, the silicone oil atomizing needle assembly 1 further comprises: an outer gas transmission tube fixing head 18 for fixing the outer gas transmission tube 17 .

[0050] Furthermore, the silicone oil atomizing needle assembly 1 further includes: a gas distributor 121 disposed on the gas transmission outer pipe 17 .

[0051] For ease of understanding, the method of use of the utility model is as follows:

[0052] Under the action of the plunger micro pump 3, the silicone oil is transported from the silicone oil storage tank 5 through the pre-pump oil delivery pipe 4, the plunger micro pump 4 and the post-pump oil delivery pipe 2 to the silicone oil atomizing needle assembly 1. The silicone oil has a certain pressure under the action of the plunger micro pump 3, and the silicone oil reaches the check cone hole 113 and pushes the check steel ball 114 open, and finally the silicone oil reaches the outlet of the oil delivery inner tube 12. The compressed air enters from the atomizing gas source connector 15, passes through the gas delivery hole 141, and enters the gas delivery outer tube 17; when the compressed air reaches the end of the gas delivery outer tube 17, under the action of the gas distributor 121, the compressed air is accelerated and reaches the outlet of the gas delivery outer tube 17; at the outlet of the silicone oil atomizing needle assembly 1, the high-speed compressed air mixes with the silicone oil, causing the silicone oil to be atomized and thus attached to the inner wall of the cartridge bottle.

[0053] In summary, the present embodiment provides a silicone oil spraying device for siliconization of the inner wall of a cartridge bottle, which replaces the peristaltic pump or time pressure valve on the market used to control the output of silicone oil with a plunger micro pump, thereby being more suitable for precise control of the output of silicone oil with high viscosity, and the plunger micro pump has a simple structure and is less disturbed by external factors; it can ultimately achieve the goal of minimizing the amount of silicone oil while ensuring that the sliding requirements of the inner wall of the cartridge bottle are met; in addition, by providing a silicone oil check component, when the equipment is suspended for a long time, the silicone oil spraying device will not reflux due to the effect of gravity, thereby improving the accuracy of the silicone oil amount after the silicone oil spraying device is restarted.

[0054] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
