Description

Technical Field

[0001] This application relates to the field of paint can spray nozzle technology, specifically to a paint can filling device that facilitates the cleaning of residue. Background Technology

[0002] In the paint canning process, the cleanliness of the paint can spray nozzles plays a crucial role in the canning quality and production efficiency. However, most paint can spray nozzles on the market currently have numerous problems in cleaning residual paint. On the one hand, the complex internal structure of the spray nozzle makes it difficult to effectively remove residual paint. Over time, this residue gradually dries and hardens, not only clogging the nozzle orifices and causing uneven paint spraying, affecting product appearance and quality, but also potentially mixing in fresh paint during subsequent canning, reducing the overall paint quality. On the other hand, existing cleaning methods often require cumbersome procedures and may even require specialized tools to disassemble the spray nozzle components. This not only consumes a lot of manpower and time but also increases the risk of spray nozzle damage, thus affecting production efficiency and costs. In addition, due to imperfect equipment design, workers may face safety hazards during cleaning operations, such as hand injuries.

[0003] Therefore, there is a need to develop a paint can spray nozzle that is easy to clean up residue, simple to operate, and safe. Summary of the Invention

[0004] In response to the aforementioned technical problems, this application solves the problem of difficulty in cleaning residual material inside paint can spray heads in the prior art.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a paint canning device that facilitates the cleaning of residual materials, comprising a canning nozzle, wherein a connecting seat and two semi-pressure rings are rotatably disposed on the canning nozzle, the connecting seat is provided with a plurality of protrusions, the semi-pressure rings are provided with grooves, the protrusions of the connecting seat are slidably disposed on the grooves of the semi-pressure rings, each semi-pressure ring is provided with a scraper, the scraper is a spiral structure and has elasticity, and a full pressure ring is rotatably installed at the end of the two scrapers away from the semi-pressure rings, the full pressure rings being slidably disposed on the canning nozzle.

[0006] Preferably, the connecting seat is provided with a sliding groove, and the canning nozzle is provided with a protruding ring that matches the sliding groove of the connecting seat. Preferably, a pawl ring is fixedly installed on the connecting seat, and the pawl ring is provided with multiple pawls.

[0007] Preferably, the canning nozzle is rotatably provided with an operating ring, and a one-way toothed ring is fixedly provided on the operating ring. The one-way toothed ring and the pawl ring form a ratchet mechanism.

[0008] Preferably, the canning nozzle is fixedly provided with multiple sliders, and a limit adjustment ring is slidably provided on the sliders. Multiple fixing blocks are fixedly provided on the end of the limit adjustment ring near the operating ring, and the operating ring is provided with a sliding groove that matches the fixing blocks.

[0009] Preferably, a stop ring is fixedly installed on the canning nozzle, and multiple sliding shafts are fixedly installed on the stop ring. Each sliding shaft is fitted with a spring, and the two ends of the spring are fixedly connected to the stop ring and the limit adjustment ring, respectively.

[0010] Multiple protective plates are fixedly installed on the limiting adjustment ring. The protective plates have a semi-circular structure and partially wrap around the spring.

[0011] The technical solution provided in this application has the following advantages compared with the prior art:

[0012] 1. The scraper blade of this application adopts a spiral structure and is elastic. Its unique multi-ended arc cross-section and large arc surface in contact with the inner wall of the nozzle increase the contact area, significantly improving the scraping ability of residual material. The protrusions on the scraper blade can guide the scraped residual material to the direction of the nozzle axis, and the spiral structure further pushes the residual material downward to accelerate its discharge, ensuring that the residual material in the canned nozzle is thoroughly cleaned, effectively reducing the impact of residual material on the quality of subsequent canned paint.

[0013] 2. The design of the full pressure ring, semi-pressure ring, and filling nozzle in this application ensures that the scraper blade is tightly connected to the inner wall of the nozzle during operation. The dimensional relationship between the mounting ring and the full pressure ring, as well as the elasticity of the scraper blade, guarantee that the scraper blade can stably conform to the inner wall of the nozzle when connected to the filling pipeline, providing a reliable structural foundation for efficient cleaning of residual materials.

[0014] 3. This application uses a ratchet mechanism composed of an operating ring, a one-way toothed ring, and a pawl ring. The operator only needs to turn the operating ring to easily drive the scraper to rotate, thereby cleaning up the residual material. The operation process is simple and quick.

[0015] 4. The limit adjustment ring and fixing block in this application can precisely limit the rotation of the operating ring when residual material is not cleaned, preventing accidental rotation of the scraper from affecting the normal painting performance of the spray head. When cleaning is required, the limit adjustment ring can be easily released manually, making the operation flexible and precise.

[0016] 5. The semi-circular protective plate on the limit adjustment ring of this application not only increases the hand area for the operator, making the operation more stable and convenient, but also effectively prevents the operator's hand from contacting the spring during operation, preventing pinching injuries caused by spring compression and improving the safety of operation.

[0017] 6. The combination design of the stop ring, sliding shaft and spring in this application enables the limit adjustment ring to automatically reset by the spring force after the restriction is released, which is convenient for the next use and reduces the safety hazards that may be caused by inaccurate manual reset.

[0018] 7. When no residual material is cleaned, the spiral structure and protrusions of the scraper can create vortices in the sprayed paint, which helps the paint to be sprayed more smoothly, increases the spraying speed, and optimizes the performance of the canned spray head under normal working conditions.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0028] like Figures 1 to 6 As shown, a paint filling device that facilitates the cleaning of residue includes a filling nozzle 101. A connecting seat 105 and two semi-pressure rings 104 are rotatably mounted on the filling nozzle 101. The connecting seat 105 is provided with multiple protrusions, and the semi-pressure rings 104 are provided with grooves. The protrusions of the connecting seat 105 are slidably mounted on the grooves of the semi-pressure rings 104. Each semi-pressure ring 104 is provided with a scraper 102. The scraper 102 has a spiral structure and a certain degree of elasticity. A full pressure ring 103 is rotatably mounted on the end of the two scrapers 102 away from the semi-pressure rings 104. The full pressure ring 103 is slidably mounted on the filling nozzle 101.

[0029] Specifically, the canning nozzle 101 includes a spray pipe and a mounting ring for connecting to the canning pipeline. The mounting ring has a threaded groove, and its inner diameter is the same as the outer diameter of the pressure ring 103, thereby ensuring the installation and rotation of the pressure ring 103. Figure 2 As shown, the inner diameter of the mounting ring is larger than the inner diameter of the nozzle, thus preventing the sliding of the full pressure ring 103 and confining it to the point where the mounting ring contacts the nozzle, i.e., the upper end of the nozzle. The initial outer diameter of the two scraper blades 102 on the full pressure ring 103 is slightly smaller than the inner diameter of the nozzle, making it easier to install the scraper blades 102 into the nozzle. After installation, when the mounting ring is not connected to the outside, the elasticity of the scraper blades 102 keeps the full pressure ring 103 in the middle position of the mounting ring, i.e., not in contact with the nozzle. When connected to an external canning pipeline, the canning pipeline gradually pushes the full pressure ring 103 downward on the mounting ring, thereby squeezing the scraper blades 102, causing them to bend and increase in diameter, making them in close contact with the inner wall of the nozzle. This ensures that when scraping away paint residue, the scraper blades 102 are stably connected to the nozzle, allowing for thorough removal of the residue.

[0030] When scraping off residual material, the operator manually controls the rotation of the semi-pressure ring 104, which in turn drives the semi-pressure ring 104 and the scraper 102 to rotate on the filling nozzle 101. Figure 3 As shown, the scraper 102 has a multi-arc cross-section, meaning the area where it contacts the inner wall of the canning nozzle 101 is a large arc surface. The diameter of this large arc surface is the same as the inner diameter of the scraper 102. A protrusion is provided on the side of the scraper 102 away from the inner wall of the canning nozzle 101. The connection between the protrusion and the large arc surface is concave towards the large arc surface, forming an approximately isosceles triangle structure with the base larger than the two sides, and the two sides concave inwards. The large arc surface of the scraper 102 increases the contact between the scraper 102 and the inner wall of the canning nozzle 101, thereby improving the scraping ability of residual material. The protrusion on the scraper 102 moves the scraped residual material towards the axis of the canning nozzle 101, while the spiral structure of the scraper 102 pushes the residual material downwards, accelerating its discharge. Figure 3 In this state, scraper 102 rotates clockwise.

[0031] like Figure 2 and Figure 4 As shown, the connecting seat 105 is provided with a sliding groove, and the canning nozzle 101 is provided with a convex ring that matches the sliding groove of the connecting seat 105. Specifically, the convex ring of the canning nozzle 101 and the circular sliding groove on the connecting seat 105 cooperate to facilitate the installation and rotation of the connecting seat 105. During rotation, the convex ring of the canning nozzle 101 restricts the connecting seat 105 and stabilizes its position.

[0032] like Figure 4 As shown, a pawl ring 106 is fixedly installed on the connecting seat 105, and multiple pawls are provided on the pawl ring 106. Specifically, a torsion spring and a rotating shaft are provided between the pawls and the pawl ring 106, so that after the pawl is pushed to rotate on the pawl ring 106 by the outside, it can be reset by the torsion spring.

[0033] like Figure 6 As shown, an operating ring 108 is rotatably mounted on the canning nozzle 101, and a one-way toothed ring 107 is fixedly mounted on the operating ring 108. The one-way toothed ring 107 and the pawl ring 106 form a ratchet mechanism.

[0034] Specifically, when the one-way gear ring 107 is driven to rotate, the one-way teeth on the one-way gear ring 107 drive the pawl on the pawl ring 106. When the pawl cannot be pushed, the pawl drives the connecting seat 105 to rotate on the canning nozzle 101 through the pawl ring 106. Then, the connecting seat 105 drives the two half-pressure rings 104 to rotate through the cam shaft, so that the two scraper blades 102 rotate on the inner wall of the canning nozzle 101 to scrape off the residue. The scraped residue falls through the internal space of the canning nozzle 101.

[0035] like Figure 1 and Figure 5 As shown, a plurality of sliders 112 are fixedly installed on the canning nozzle 101. A limit adjustment ring 110 is slidably installed on the slider 112. A plurality of fixing blocks 109 are fixedly installed on the end of the limit adjustment ring 110 near the operating ring 108. The operating ring 108 is provided with a sliding groove that matches the fixing blocks 109.

[0036] Specifically, by setting up the operating ring 108, when the operator controls the operating ring 108 to rotate on the canning nozzle 101, the operating ring 108, because it is fixedly connected to the one-way toothed ring 107, drives the one-way toothed ring 107 to rotate, thereby driving the connecting seat 105 and the scraper 102. When the scraping of residual material is not required, the fixed block 109 on the limit adjustment ring 110 restricts the operating ring 108 to prevent accidental activation and drive the scraper 102 to rotate, which would affect the performance of the paint spraying inside the canning nozzle 101. That is, it prevents the rotation of the scraper 102 from changing the path of the paint spraying, which may cause forking or other problems. When the scraper 102 does not rotate, the spiral structure and the protrusions of the scraper 102 will cause the sprayed paint to generate vortices, thereby helping the paint to spray out and increasing the spraying speed.

[0037] like Figures 1 to 5 As shown, a stop ring 113 is fixedly installed on the canning nozzle 101. Multiple sliding shafts 114 are fixedly installed on the stop ring 113. A spring 115 is sleeved on each sliding shaft 114. The two ends of the spring 115 are fixedly connected to the stop ring 113 and the limit adjustment ring 110, respectively.

[0038] Specifically, when it is necessary to release the restriction of the fixed block 109 on the operating ring 108 on the limiting adjustment ring 110, the operator manually controls the limiting adjustment ring 110 to slide upward on the slider 112 of the canning nozzle 101, thereby causing the fixed block 109 to disengage from the operating ring 108 and release the restriction. When the limiting adjustment ring 110 moves upward, it slides on the sliding shaft 114 and compresses the spring 115 on the sliding shaft 114. Subsequently, when it is necessary to restore the restriction of the fixed block 109 on the operating ring 108, the limiting adjustment ring 110 is pushed by the elastic force of the spring 115 to achieve reset.

[0039] like Figure 5 As shown, multiple protective plates 111 are fixedly installed on the limiting adjustment ring 110. The protective plates 111 have a semi-circular structure and partially wrap around the spring 115.

[0040] Specifically, when the operator manually controls the limit adjustment ring 110 to move upward on the can dispenser nozzle 101, they can hold the limit adjustment ring 110 and the protective plate 111 with their hands, thereby increasing the operator's hand area and ensuring the stability and convenience of controlling the limit adjustment ring 110. It can also prevent the operator from coming into contact with the spring 115, thus avoiding injury to the operator's hand from the compression of the spring 115 itself when it is compressed, i.e., the reduced pitch and the risk of pinching the hand.

[0041] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
