Description

Technical Field

[0001] This utility model relates to the field of filling equipment technology, specifically to a filling mechanism for coated emulsions. Background Technology

[0002] Coating emulsions are key materials in construction, automotive, furniture, and electronics industries, widely used for surface protection, decoration, and functional coatings. Typical applications include waterproof coatings, industrial anti-corrosion paints, automotive primers, and electronic encapsulation adhesives. The filling process is the final critical step in coating emulsion production, directly impacting product quality, production costs, and market competitiveness.

[0003] The coating emulsion is pre-stored in the barrel. The coating emulsion is extracted from the barrel by a negative pressure suction device and fed into the feed pipe. Finally, it exits from the filling head and enters the bottle. During the filling process, when the outlet is idle or the bottle has finished receiving the coating emulsion, there is coating emulsion remaining inside the filling head. Due to inertia, the coating emulsion is prone to dripping onto the conveyor table, causing contamination of the conveyor table and affecting the filling efficiency and quality. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a filling mechanism for coated emulsions, which solves the problem that during the filling process, when the bottle or can is empty, residual coated emulsion inside the filling head can easily drip onto the conveyor table, causing contamination of the conveyor table and affecting filling efficiency and quality.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution: A filling mechanism for coated emulsions includes a filling head, a sealing rod, and an electric push rod. The filling head is fixedly mounted on the frame of the filling station of the filling equipment and is connected to the conveying pipe of the storage tank through a feed pipe. A sealing rod is installed in the cavity inside the filling head. The guide plug integrally set at the lower end of the sealing rod initially seals the discharge port at the lower end of the filling head. The upper end of the sealing rod is drivenly connected to the output end of the electric push rod.

[0006] Furthermore, an outwardly extending arc-shaped sealing and contact lip plate is provided at the discharge port of the lower end of the filling head. The arc-shaped sealing and contact lip plate matches the sealing and contact surface provided on the guide plug, and the two have the same curvature. The filling head has a feed inlet at the corresponding feed pipe position. The feed pipe is connected to the internal cavity of the filling head through the feed inlet. The upper part of the filling head is integrally provided with an end plate, which is fixedly connected to the mounting seat of the electric push rod.

[0007] Furthermore, the guide plug at the lower end of the sealing rod is an inverted cone shape, and the sealing contact surface is at the transition part where the upper part of the guide plug connects with the rod body; The sealing rod is located on the rod body inside the filling head cavity and an adjusting piston is also installed. The adjusting piston slides against the side wall of the filling head cavity cavity. The sealing sleeve provided at the lower part of the adjusting piston is slidably connected to the rod body of the sealing rod. A sealing ring is installed between the sealing sleeve and the rod body. A limit sleeve is provided at the upper part of the adjusting piston. A deformation groove is opened on the limit sleeve, and a fastening nut is threaded on the limit sleeve. The limiting sleeve is provided with a threaded connection area that is small at the top and large at the bottom, and the fastening nut is provided with a frustum-shaped threaded hole that matches the threaded connection area.

[0008] Compared with the prior art, the present invention provides a filling mechanism for coated emulsions, which has the following beneficial effects: This invention features a sealing rod installed on the filling head to block the discharge port. The sealing rod moves along with the guide plug, effectively sealing the discharge port after filling to prevent residual coating emulsion from dripping and contaminating the equipment. An adjustable piston is used to adjust the volume of the storage chamber inside the filling head, allowing the filling volume to be determined directly, thus improving filling efficiency and quality. The overall structure is simple and easy to use. Attached Figure Description

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Example like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown in one embodiment of this utility model, a filling mechanism for coating emulsions includes a filling head 1, a sealing rod 2, and an electric push rod 3. The filling head 1 is fixedly mounted on the frame of the filling equipment at the filling station, facilitating stable installation and use of the mechanism for filling coating emulsions. The filling head 1 is connected to the conveying pipe of the storage tank via a feed pipe 101, allowing the coating emulsion to be smoothly injected into the filling head 1 for subsequent filling operations. A sealing rod 2 is installed in the cavity inside the filling head 1. The material guide plug 201, which is integrally set at the lower end of the sealing rod 2, is initially sealed in the discharge port 102 at the lower end of the filling head 1. The upper end of the sealing rod 2 is connected to the output end of the electric push rod 3 for transmission. This allows the electric push rod 3 to drive the sealing rod 2 to smoothly move the material guide plug 201 out of the discharge port 102 during use, thereby opening the discharge port 102 and allowing the filling head 1 to smoothly discharge from the discharge port 102, thus completing the filling operation.

[0013] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, an outwardly extending arc-shaped sealing lip is provided at the discharge port 102 at the lower end of the filling head 1. The arc-shaped sealing lip matches the sealing contact surface 202 provided on the guide plug 201, and the two have the same curvature, so that the discharge port 102 can be stably sealed after the two come together. After the two separate, the discharge port 102 can be opened smoothly. A feed inlet is provided on the filling head 1 at the location corresponding to the feed pipe 101. The feed pipe 101 is connected to the internal cavity of the filling head 1 through the feed inlet, which facilitates the smooth injection of the coating emulsion in the storage tank into the internal cavity of the filling head 1. An end plate 103 is integrally provided on the upper part of the filling head 1. The end plate 103 is fixedly connected to the mounting seat of the electric push rod 3, which facilitates the stable installation of the electric push rod 3 on the filling head 1, so that the two can be used in a stable manner. The electric push rod 3 is a known existing technology, so it will not be described in detail.

[0014] like Figure 2 , Figure 4 and Figure 5As shown, in some embodiments, the guide plug 201 at the lower end of the sealing rod 2 is an inverted cone shape, which facilitates the flow of the coating emulsion onto the guide plug 201. Under the action of the inverted cone shape, the coating emulsion will concentrate and flow to the middle position at the lower end, thereby facilitating better flow into the packaging bottle, achieving stable filling, improving efficiency, and the sealing contact surface 202 at the transition part where the upper part of the guide plug 201 connects with the rod body, which facilitates cooperation with the outlet 102 of the filling head 1, thereby providing a stable and effective seal and preventing residual coating emulsion from dripping onto the equipment; An adjusting piston 4 is also installed on the rod body of the sealing rod 2 located inside the cavity of the filling head 1. The adjusting piston 4 slides against the side wall of the cavity inside the filling head 1, and the sealing sleeve 401 set at the lower part of the adjusting piston 4 is slidably connected to the rod body of the sealing rod 2. A sealing ring is installed between the sealing sleeve 401 and the rod body to stably seal the adjusting piston 4 and the rod body of the sealing rod 2, so that the adjusting piston 4 can separate the cavity inside the filling head 1. After the position is adjusted, the volume of the temporary storage cavity inside the filling head 1 can be effectively adjusted. The upper part of the adjusting piston 4 is provided with a limiting sleeve 402. The limiting sleeve 402 has a deformation groove 404, which allows for appropriate deformation when the fastening nut 403 comes into contact with the limiting sleeve 402, so that the limiting sleeve 402 can tightly grip the rod body. The limiting sleeve 402 is threadedly connected to the fastening nut 403. The limiting sleeve 402 has a threaded connection area with a smaller upper end and a larger lower end. The fastening nut 403 has a frustum-shaped threaded hole that matches the threaded connection area. During use, it is convenient to directly rotate the fastening nut 403 on the limiting sleeve 402. As the fastening nut 403 is continuously rotated, the frustum-shaped threaded hole will come into contact with the threaded connection area on the limiting sleeve 402, so that the limiting sleeve 402 tightly comes into contact with the rod body of the sealing rod 2, achieving a stable connection between the adjusting piston 4 and the sealing rod 2, so that the two can move synchronously in the filling head 1. Meanwhile, during use, the volume of the temporary storage chamber inside the filling head 1 can be adjusted by adjusting the position of the adjusting piston 4 on the sealing rod 2, so as to achieve flexible adjustment of the filling volume per batch and facilitate use.

[0015] During the filling process of the coating emulsion, the coating emulsion in the storage tank of the filling equipment is injected into the internal cavity of the filling head 1 through the conveying pipe and the feed pipe 101. After the injection of the coating emulsion is completed, the electric push rod 3 drives the sealing rod 2 to move in the filling head 1, driving the guide plug 201 to move away from the outlet 102 of the filling head 1, opening the outlet 102, and the coating emulsion in the filling head 1 flows out from the outlet 102, flowing with the rod to the guide plug 201. The emulsion flows from the guide plug 201 into the packaging bottle. All the coating emulsion in the filling head 1 flows out. After filling is completed, the electric push rod 3 drives the guide plug 201 to reset. The sealing contact surface 202 on the guide plug 201 is attached to the arc-shaped sealing contact lip plate at the outlet 102, sealing the outlet 102 of the filling head 1, thereby preventing the residual coating emulsion on the filling head 1 from dripping down and ensuring that the equipment is clean and tidy.

[0016] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
