Description

Technical Field

[0001] This utility model relates to the field of ointment filling technology, and in particular to an anti-splash ointment dispensing nozzle. Background Technology

[0002] In ointment manufacturing enterprises, efficient filling equipment and nozzles are needed to improve production efficiency and reduce costs. At the same time, to ensure the stability and consistency of product quality, the nozzles need to be able to precisely control the filling volume of the ointment, avoiding product quality problems caused by uneven filling.

[0003] Existing injection nozzles typically employ a downward-pressing piston design. However, this structure causes the paste to splash out of the injection tube during the pressing process of the pressure rod, resulting in paste waste and contamination of the worktable.

[0004] Therefore, an anti-splatter paste nozzle is proposed to solve the above problems. Utility Model Content

[0005] Given that the existing injection nozzles typically employ a downward-pressing piston design, but this structure causes the paste to splash out of the injection tube during the pressing of the pressure rod, this utility model is proposed.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an anti-splatter ointment injection nozzle, which includes a nozzle body and a pressure rod. The nozzle body includes a nozzle body main body, a nozzle body inlet, and a spacer ring. The nozzle body inlet is located at the top of the nozzle body main body, and the spacer ring is located near the outlet of the nozzle body main body. The pressure rod includes a pressure rod main body, an injection block, and a pressure rod connecting end arranged from bottom to top.

[0007] Preferably, the mouthpiece body is a hollow cylindrical tube.

[0008] Preferably, the injection block is located below the spacer ring, and the diameter of the injection block is larger than the inner diameter of the spacer ring and smaller than the inner diameter of the nozzle body.

[0009] Preferably, the nozzle inlet includes an upper part and a lower part, the lower part being a frustum and the upper part being a cylinder.

[0010] Preferably, the diameter of the connecting end of the pressure rod is larger than the diameter of the main body of the pressure rod.

[0011] The beneficial effects of this utility model are:

[0012] By setting a cylindrical nozzle body and installing a spacer ring in the lower part of the nozzle body, the pressure rod is inserted into the nozzle body from bottom to top and the pressure injection block is located below the spacer ring. This changes the existing top-down punching injection method to a bottom-up pumping injection method, avoiding the ointment from splashing out of the nozzle body, which would cause waste of ointment and contamination of the worktable. At the same time, adjusting the gap between the injection block and the nozzle outlet can control the ointment flow rate. Attached Figure Description

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Reference Figures 1 to 3 In one embodiment of this utility model, an anti-splash ointment dispensing nozzle is provided. This anti-splash ointment dispensing nozzle includes a nozzle body 1 and a pressure rod 2. The nozzle body 1 includes a nozzle body main body 11, a nozzle body inlet 12 and a spacer ring 13. The nozzle body inlet 12 is located at the top of the nozzle body main body 11, and the spacer ring 13 is located near the outlet of the nozzle body main body 11. The pressure rod 2 includes a pressure rod main body 21, a dispensing block 22 and a pressure rod connecting end 23 arranged from bottom to top.

[0023] Specifically, the nozzle body 1 includes a nozzle body 11, a nozzle inlet 12, and a spacer ring 13. The nozzle body 11 is a hollow cylindrical tube. The spacer ring 13 is located inside the nozzle body 11 near the outlet but is at a height relative to the outlet to ensure that the injection block 22 is completely retracted into the nozzle body 11.

[0024] Specifically, the lower part of the nozzle inlet 12 is a small truncated cone, and the upper part is a cylinder. This structure is more conducive to injecting ointment into the nozzle 1.

[0025] Specifically, the pressure rod 2 includes a pressure rod body 21, an injection block 22, and a pressure rod connecting end 23 arranged from bottom to top. The pressure rod connecting end 23 is connected to the filling machine in the existing equipment. The diameter of the pressure rod connecting end 23 is larger than the diameter of the pressure rod body 21, and the pressure rod connecting end 23 smoothly transitions with the pressure rod body 21. The injection block 22 is located at the bottom of the pressure rod body 21. The bottom of the injection block 22 is cylindrical, and the upper part smoothly transitions with the pressure rod body 21. The injection block 22 is located below the spacer ring 13. The diameter of the injection block 22 is larger than the inner diameter of the spacer ring 13 and smaller than the inner diameter of the nozzle body 11 to ensure that the ointment does not flow out of the nozzle body 1 when the pressure rod 2 and the nozzle body 1 are closed.

[0026] During use, the pressure rod 2 is inserted into the nozzle body 1 from below. When injection begins, the injection block 22 is located outside the nozzle body 1, and the injection speed can be controlled by the gap between the injection block 22 and the outlet of the nozzle body 11. When it is necessary to stop injection, the injection rod 2 is pulled upward, the injection block 22 enters the nozzle body 1 and is locked by the spacer ring 13, blocking the opening of the spacer ring 13 and preventing the ointment from flowing out. The upward injection method avoids the ointment splashing out of the nozzle body 1.

[0027] Reference Figures 4 to 5 This is an existing injection nozzle. Its working principle is as follows: the injection rod 2 presses downward, and the injection block 23 squeezes and squeezes the paste in the nozzle body 1 out of the nozzle body 1. During the squeezing process, the paste is very easy to splash out from the top of the nozzle body 1.

[0028] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
