Description

Technical Field

[0001] The utility model belongs to the technical field of printing and dyeing equipment, and in particular relates to a color paste filling valve capable of adjusting the direction of fluid. Background Art

[0002] Rotary screen printing uses a scraper to apply pressure to the color paste within a rotary screen onto the fabric. It boasts high production efficiency and strong fabric adaptability, resulting in vibrant patterns and vibrant colors. Rotary screen printing can typically produce 6 to 20 colors. The printing paste is prepared using dye solutions of varying color numbers. During the preparation process, the various dye solutions are added according to the recipe using pipes and filling valves into the paste barrel. The barrel is then transferred to a mixing station for mixing and agitation to create the various colors of production paste. Traditional filling valves are fixedly mounted on a bracket, with a fixed discharge angle and non-adjustable discharge direction. This can easily lead to paste spillage if the barrel is misplaced from its intended position. Summary of the Invention

[0003] Aiming at the technical problem that the liquid outlet direction of the existing color paste filling valve cannot be adjusted, the utility model proposes a color paste filling valve with a liquid outlet nozzle with freely adjustable direction, which is convenient for adjusting the fluid direction.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A color paste filling valve with adjustable fluid direction comprises a cylinder, the lower end of the cylinder is connected to a feed pipe, and the lower end of the feed pipe is connected to a guide pipe; the cylinder comprises a cylinder shell, a first air vent and a second air vent are provided on the cylinder shell, an upper piston and a lower piston, and a piston rod penetrating the upper piston and the lower piston and extending to the guide pipe are installed in the cylinder shell; the feed pipe is provided with a feed port, and a sealing member is provided at a position above the feed port in the feed pipe; a discharge nozzle is provided at the lower end of the guide pipe, a sealing head for sealing the discharge nozzle is installed at the lower end of the piston rod, a connecting ring is installed at the lower end of the discharge nozzle, a hollow universal ball is installed in the connecting ring, and a universal nozzle extending from the connecting ring is provided at the lower end of the universal ball.

[0006] Preferably, the cylinder housing and the discharge pipe are connected via threads.

[0007] Preferably, the feed pipe and the guide pipe are connected by threads, and a sealing ring is provided at the connection surface.

[0008] Preferably, the discharge nozzle is provided with an external thread, the connecting ring is provided with an internal thread, and a through hole is provided on the lower end surface of the connecting ring.

[0009] Preferably, the lower end of the sealing head is tapered, and the lower end of the guide tube is provided with a tapered hole matching the sealing head.

[0010] Preferably, the universal nozzle is conical.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] The color paste filling valve of the utility model adopts a split structure, and components that are easy to fail, such as a sealing member and a sealing head, can be disassembled and replaced, thereby extending the service life of the filling valve.

[0013] A universal nozzle is installed at the bottom of the filling valve to adjust the liquid outlet angle.

[0017] In order to better understand the present invention, the following is a detailed description with reference to the accompanying drawings and embodiments.

[0018] Example: Figure 1 The figure shows a color paste filling valve with adjustable fluid direction. It includes a cylinder 1 at the top, with a feed pipe 2 connected to the lower end of the cylinder 1, which in turn is connected to a guide pipe 3. The cylinder 1 includes a cylinder housing 11, which is provided with a first air vent 12 and a second air vent 13 that communicate with the interior of the cylinder 1. An upper piston 14 and a lower piston 15 are mounted within the cylinder housing 11, along with a piston rod 16 that passes through the upper and lower pistons 14, 15 and extends to the guide pipe 3. Compressed air is supplied to the first air vent 12 or the second air vent 13, causing the piston rod 16 to reciprocate upward and downward.

[0019] The feed pipe 2 is provided with a feed port 21, which is connected to the color paste storage tank via a pipeline. The color paste storage tank provides the required color paste. A seal 22 is provided above the feed port 21 within the feed pipe 2. This seal 22 seals the space between the feed pipe 2 and the piston rod 16, preventing the color paste from entering the cylinder 1. The feed pipe 2 is connected to the cylinder housing 11 via a threaded connection, forming a detachable structure. If the seal 22 fails due to long-term use, the feed pipe 2 can be separated from the cylinder 1 and replaced, thereby extending the service life of the filling valve.

[0020] The guide tube 3 is provided with a discharge nozzle 31 at its lower end, and a sealing head 17 is mounted at the lower end of the piston rod 16 to seal the discharge nozzle 31. When the piston rod 16 is in the upper position, a gap exists between the sealing head 17 and the discharge nozzle 31, allowing the color paste to enter the guide rod through the feed port 21 and then flow out through the discharge nozzle 31. When the piston rod 16 moves downward to the lower position, the sealing head 17 presses down on the discharge nozzle 31, blocking the discharge nozzle 31 and closing the filling valve, stopping the discharge. The lower end of the sealing head 17 is tapered, and the lower end of the guide tube 3 is provided with a tapered hole that matches the sealing head 17 to facilitate effective sealing. After long-term use, the sealing head 17 loses its sealing effectiveness and is prone to leakage. To facilitate replacement of the sealing head 17, the feed tube 2 and the guide tube 3 in this embodiment are connected by a threaded connection, and a sealing ring 4 is provided at the connection surface. When the sealing head 17 needs to be replaced, it can be easily replaced by unscrewing the guide tube 3, making it easy to operate.

[0021] like Figure 2 As shown, the lower end of the discharge nozzle 31 is mounted with a connecting ring 5, within which a hollow universal ball 6 is mounted. The lower end of the universal ball 6 is provided with a universal nozzle 7 extending from the connecting ring 5. Specifically, the discharge nozzle 31 is provided with external threads, while the connecting ring 5 is provided with internal threads. The lower end surface of the connecting ring 5 is provided with a through hole. The inner diameter of the connecting ring 5 is slightly larger than the outer diameter of the universal ball 6, while the diameter of the through hole is smaller than that of the universal ball 6. Therefore, the universal ball 6 is engaged within the connecting ring 5 and can rotate within it a certain angle, thereby changing the direction of the universal nozzle 7 and, in turn, the direction of the liquid discharge. If the color paste barrel deviates from the predetermined position, the operator can swing the universal nozzle 7 to align it with the barrel opening. This is more convenient than moving the barrel. After the filling level rises, the liquid discharge angle can also be adjusted to prevent slurry from splashing outside the barrel. The conical shape of the universal nozzle 7 prevents the liquid at the discharge nozzle from dispersing as a mist when the filling valve closes, causing leakage.

[0022] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
