Description

Technical Field

[0001] This utility model relates to the field of paint filling technology, specifically a leak-proof and residue-proof paint filling head. Background Technology

[0002] Paint can be applied to the surface of objects to be protected or decorated, and can form a continuous film that adheres firmly to the object. During production, paint is filled into containers through a filling head. Paint is relatively viscous and will drip during filling, so there are often thread-like marks on the edge of the container.

[0003] For example, patent document CN202323123415.1 discloses an anti-drip filling head, including a filling head body, a conical filling nozzle at the bottom of the filling head body, a feed inlet on one side of the filling head body, and a retractable sealing rod inside the filling head body. A support rod is installed at the top of the filling head body, with a through hole inside the support rod. A cylinder is installed at the top of the support rod, and the telescopic end of the cylinder passes through the through hole in the support rod and connects to the top of the sealing rod. The cylinder controls the extension and retraction of the sealing rod to seal or open the conical filling nozzle. A rotatable support plate is also provided below the conical filling nozzle, with a groove at the top. This utility model effectively prevents liquid from dripping from the filling head body and causing contamination. It is convenient and reliable to use, with a simple and ingenious structural design and strong practicality.

[0004] The filling head has a rotatable support plate on the underside of the conical filling nozzle, which can collect dripping paint through grooves. However, in practice, the paint dripping from the bottom of the filling nozzle will be stretched due to its viscosity and continue to fall. The rotating support plate will cut off the stretched paint in the middle, so the paint will stick to the surface of the support plate and cannot be effectively collected. Furthermore, the stretched paint is pushed by the support plate, which will increase the area of ​​paint contamination and make cleaning more difficult.

[0005] Therefore, there is an urgent need to design a leak-proof and residue-proof coating filling head to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a leak-proof and residue-proof paint filling head to solve the problem mentioned in the background art. In the prior art, the filling head has a rotatable support plate on the lower side of the conical filling nozzle. The dripping paint can be collected through the groove. However, in practice, the paint dripping from the bottom of the filling nozzle will be stretched and continuously descend due to the viscosity of the paint itself. The rotating support plate will cut off the stretched paint in the middle. Therefore, the paint will adhere to the surface of the support plate and cannot be effectively collected. Moreover, the stretched paint is pushed by the support plate, which will increase the area of ​​paint contamination and increase the difficulty of cleaning.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof and residue-proof coating filling head, comprising a filling tube, a filling nozzle at the bottom of the filling tube, a feed pipe on the side wall of the filling tube, an opening and closing cylinder on the top surface of the filling tube, and a collection structure on the filling tube. The collection structure includes a positioning clamp, which is fixedly installed on the outer wall of the filling tube. A fixing frame is fixedly connected to the surface of the positioning clamp. A pushing cylinder is fixedly installed at the lower end of the fixing frame. A moving block is fixedly connected to the extended end of the pushing cylinder. A Z-shaped guide groove is formed on the left side wall of the moving block. A threaded connecting sleeve is integrally formed on the bottom surface of the moving block. A collection bottle is fixedly installed on the inner side of the threaded connecting sleeve by threads.

[0008] Preferably, the pushing cylinder is horizontally positioned and located below the filling nozzle.

[0009] Preferably, the bottom of the filling nozzle is located inside the moving block, and the bottom surface of the filling nozzle is in contact with the upper inner wall of the Z-shaped guide groove.

[0010] Preferably, the Z-shaped guide channel has a "Z"-shaped structure, with the middle part of the Z-shaped guide channel being inclined and the upper and lower ends being horizontal.

[0011] Preferably, the lower end of the Z-shaped guide groove communicates with the threaded connecting sleeve and the inside of the collection bottle.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The filling head has a push cylinder installed on the lower side of the filling nozzle. After filling is completed, the push cylinder is activated, which can drive the moving block to move laterally. When the moving block moves, it can contact the dripping and stringing paint through the Z-shaped guide groove, so that the dripping paint is collected on the inner side of the Z-shaped guide groove, and the paint will slide down along the inner wall of the Z-shaped guide groove, eventually flowing down to the inner side of the collection bottle, so that the paint can be collected through the collection bottle.

[0014] This filling head, by vertically oriented with a long, narrow movable block on the lower side of the filling nozzle, increases the vertical span of the Z-shaped guide channel. This allows the Z-shaped guide channel to contact the dripping paint, ensuring effective paint collection. As the movable block moves, the upper end of the Z-shaped guide channel contacts the bottom end of the filling nozzle, scraping away residual paint from the bottom of the nozzle. This keeps the nozzle clean and prevents residual, clump-like paint from being flushed into the container during filling, thus ensuring product quality. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1-4 One embodiment provided by this utility model:

[0022] A leak-proof and residue-proof paint filling head includes a filling tube 1, a filling nozzle 11 at the bottom of the filling tube 1, a feed pipe 12 on the side wall of the filling tube 1, an opening / closing cylinder 13 on the top surface of the filling tube 1, and a collection structure 2 on the filling tube 1. The collection structure 2 includes a positioning clamp 21, which is fixedly installed on the outer wall of the filling tube 1. A fixing frame 22 is fixedly connected to the surface of the positioning clamp 21. A pushing cylinder 23 is fixedly installed at the lower end of the fixing frame 22. A moving block 24 is fixedly connected to the extended end of the pushing cylinder 23. A Z-shaped guide groove 25 is formed on the left side wall of the moving block 24. A threaded connecting sleeve 26 is integrally formed on the bottom surface of the moving block 24. A collection bottle 27 is fixedly installed on the inner side of the threaded connecting sleeve 26 by threads. After filling is completed, the pushing cylinder 23 is activated, which can drive the moving block 24 to move laterally. When the moving block 24 moves... The Z-shaped guide channel 25 can contact the dripping paint, allowing the dripping paint to be collected on the inner side of the Z-shaped guide channel 25. The paint will slide down the inner wall of the Z-shaped guide channel 25 and eventually flow down to the inner side of the collection bottle 27 for collection. The moving block 24 is vertically arranged and has a long strip structure, which can increase the vertical span of the Z-shaped guide channel 25, allowing the Z-shaped guide channel 25 to contact the dripping paint and ensuring the effective collection of paint by the Z-shaped guide channel 25. As the moving block 24 moves, the upper end of the Z-shaped guide channel 25 can contact the bottom end of the filling nozzle 11 to prevent paint leakage. The Z-shaped guide channel 25 can also scrape off the paint residue at the bottom of the filling nozzle 11, keeping the filling nozzle 11 clean and preventing residual clumps of paint from being flushed into the container during filling, thus maintaining product quality.

[0023] Furthermore, the push cylinder 23 is set horizontally and located below the filling nozzle 11, providing power for the movement of the moving block 24 below the filling nozzle 11.

[0024] Furthermore, the bottom of the filling nozzle 11 is located inside the moving block 24, and the bottom surface of the filling nozzle 11 is in contact with the upper inner wall of the Z-shaped guide channel 25. When the moving block 24 moves, it can scrape off the coating residue that has clumped at the bottom of the filling nozzle 11 through the Z-shaped guide channel 25, so as to avoid the coating residue at the bottom of the filling nozzle 11 and prevent the coating from falling into the container, thus ensuring the quality of the product.

[0025] Furthermore, the Z-shaped guide channel 25 has a "Z"-shaped structure. The middle part of the Z-shaped guide channel 25 is inclined, and the upper and lower ends are horizontal. The length of the middle part of the Z-shaped guide channel 25 is greater than the length of the dripping paint, so that the bottom of the dripping paint is located entirely in the middle of the Z-shaped guide channel 25, thereby ensuring the collection effect of the Z-shaped guide channel 25 on the dripping paint.

[0026] Furthermore, the lower end of the Z-shaped guide channel 25 communicates with the inside of the threaded connecting sleeve 26 and the collection bottle 27, and the paint collected inside the Z-shaped guide channel 25 can be collected inside the threaded connecting sleeve 26 and the collection bottle 27.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
