Description

Technical Field

[0001] This utility model relates to the field of filling equipment technology, and in particular to a splash-proof quantitative filling device for chromium-free fingerprint-resistant liquid. Background Technology

[0002] Chromium-free fingerprint-resistant liquid, as an environmentally friendly surface treatment agent, is widely used in the hardware, building materials, home appliance, and electronics manufacturing industries. During the production and packaging process, this liquid needs to be precisely dispensed from storage tanks into containers of different sizes to facilitate subsequent storage, transportation, and use.

[0003] In traditional quantitative filling operations, when liquids (especially corrosive or high-value chemical liquids) are injected into containers from the nozzle, the flow rate and impact can easily cause liquid rebound, leading to splashing. This splashing phenomenon not only wastes expensive liquids but can also corrode equipment, pollute the working environment, and even threaten the safety of operators.

[0004] To mitigate splashing issues, existing technologies often employ splash guards around the nozzle. However, these splash guards are typically designed for specific container neck sizes, resulting in relatively fixed structures. In actual production, customer needs are diverse, and the diameter and height of filling container necks frequently vary. When using these fixed-structure splash guards, it's difficult to effectively fit all neck sizes, leading to gaps between the splash guard and the neck. Liquid can still easily splash out through these gaps, significantly reducing the splash-proof effect.

[0005] Furthermore, the stability of the container during the filling process directly affects the splash-proof effect. If the container is not accurately positioned on the filling platform, or if it shakes slightly under the impact of liquid injection, the nozzle may become misaligned with the bottle neck, exacerbating liquid splashing. Existing filling platforms often lack integrated solutions that can accommodate different container sizes and provide stable locking.

[0006] Therefore, existing filling equipment generally suffers from a core problem: it is difficult to simultaneously achieve efficient anti-splash function, rapid adaptability to containers of different sizes, and positioning stability during the filling process, resulting in low filling efficiency and difficulty in ensuring a clean working environment.

[0007] Therefore, this utility model proposes a splash-proof quantitative filling device for chromium-free fingerprint-resistant liquid to overcome the shortcomings of the prior art. Utility Model Content

[0031] 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.

[0032] Please refer to Figures 1 to 6 This utility model provides a splash-proof quantitative filling device for chromium-free fingerprint-resistant liquid, which aims to solve the problems in the prior art where liquid is prone to splashing and polluting the environment during the filling process, and where the lack of an effective positioning structure for containers of different sizes leads to inaccurate filling alignment.

[0033] like Figure 1 and Figure 2As shown, the splash-proof quantitative filling equipment for chromium-free fingerprint-resistant liquid mainly includes a control mechanism 1, a liquid tank 103, a splash-proof mechanism 2, and a positioning mechanism 3. The control mechanism 1, as the power and control core of the entire equipment, includes a main unit 101, a control panel 102 located at the front of the main unit 101, and a pump body 104, a flow controller 107, and a water injector 105 all located on the sides of the main unit 101. The main unit 101 provides the mounting carrier and support foundation for various electrical components and mechanical parts. The control panel 104... 2 is used to display filling parameters and receive operation instructions to realize human-machine interaction. The pump body 104, flow controller 107 and water injector 105 are arranged on the side of the main unit 101, which is conducive to optimizing the spatial layout of the equipment and facilitating pipeline connection and maintenance. The liquid tank 103 is fluidly connected to the pump body 104 through the water pipe 106. Specifically, the water pipe 106 is connected in sequence to the bottom of the liquid tank 103, the inlet of the pump body 104, the inlet of the flow controller 107 and the inlet of the water injector 105, thereby constructing a complete liquid transmission channel.

[0034] The anti-splash mechanism 2 is located below the water injector 105 and is used to shield and protect the container opening during filling. The anti-splash mechanism 2 includes a water outlet 209 extending downward and fixedly connected to the bottom of the water injector 105, a backing plate 202 sleeved on the outer wall of the water outlet 209, an anti-splash cover 201 sleeved on the outer wall of the water outlet 209, and an adjustable clamping mechanism surrounding the outer wall of the backing plate 202. The water outlet 209, as the final outlet of the liquid, adopts a detachable structure for easy replacement and cleaning. The backing plate 202, together with the adjustable clamping mechanism, can achieve a stable installation of the anti-splash component on the water outlet 209. The anti-splash cover 201 is used to cover the container opening to physically block liquid splashing. The adjustable clamping mechanism can fix or release the backing plate 202 on the outer wall of the water outlet 209, thereby adjusting the height of the anti-splash component or disassembling it.

[0035] The positioning mechanism 3 is located below the splash-proof mechanism 2 and is used to support and fix the container to be filled. The positioning mechanism 3 includes a horizontally arranged support plate 306, a slide groove 307 set on the top of the support plate 306, a control plate 303 slidably engaged in the slide groove 307, a positioning arc plate 302 fixedly connected to one end of the control plate 303, and a locking mechanism for locking the position of the control plate 303 along the slide groove 307. The support plate 306 provides a stable placement platform. The control plate 303 can slide in the slide groove 307 to drive the positioning arc plate 302 to move, thereby adapting to the positioning requirements of containers of different sizes. The locking mechanism is used to lock the control plate 303 after the position adjustment is completed to prevent the container from shifting during the filling process.

[0036] The adjustable clamping mechanism includes a locking ring 207, a clamping plate rotating shaft 206, a first clamping plate 210, a second clamping plate 211, and a drive assembly. The outer wall of the locking ring 207 fits against the outer wall of the abutment plate 202 as a mounting base. The clamping plate rotating shaft 206 is used to realize the relative rotation between the first clamping plate 210 and the second clamping plate 211. The first clamping plate 210 and the locking ring 207 are rotatably connected by a first sleeve 212. The second clamping plate 211 and the locking ring 207 are rotatably connected by a connecting plate rotating shaft 208. The first clamping plate 210 and the second clamping plate 211 are arranged opposite to each other. The first clamping plate 210 and the second clamping plate 211 cooperate to clamp the outer wall of the abutment plate 202. For convenient operation, the adjustable clamping mechanism also includes a lever plate 204, a second sleeve 213, a connecting plate 205, and a drive assembly. The aforementioned first sleeve 212 and the lever 204 are rotatably connected to the side of the locking ring 207. The second sleeve 213 is rotatably connected to one end of the lever 204. One end of the connecting plate 205 is rotatably connected to the second sleeve 213, and the other end of the connecting plate 205 is rotatably connected to the other side of the locking ring 207 via the connecting plate shaft 208. The first sleeve 212 is rotatably connected between the other side of the locking ring 207 and the first clamping plate 210. The lever 204 drives the first clamping plate 210 and the second clamping plate 211 to tighten or open through the linkage structure formed by the second sleeve 213, the connecting plate 205, the connecting plate shaft 208 and the first sleeve 212. This multi-link linkage structure ensures that the splash guard 201 can be quickly and firmly fixed on the water outlet 209, while ensuring the uniformity of the clamping force.

[0037] At the same time, the positioning mechanism 3 is equipped with a locking mechanism for fixing the position. Please refer to [reference needed]. Figure 5 The locking mechanism includes a locking knob 304 and a locking groove 305. The locking knob 304 is located above the support plate 306, and the locking groove 305 is located on the side of the control plate 303. In the assembled state, the locking knob 304 and the locking groove 305 are locked by threaded engagement. When the control plate 303 slides to the appropriate position in the slide groove 307, the locking knob 304 is tightened so that its end abuts against or is engaged with the locking groove 305. This threaded locking engagement structure ensures the high stability and anti-displacement capability of the control plate 303 and the positioning arc plate 302 during the filling operation, effectively preventing filling deviations caused by container shaking.

[0038] In addition, the splash guard 201 is also provided with a pressure relief hole 203, which is located at the top of the splash guard 201 and is used to balance the internal and external air pressure during filling.

[0039] The specific drive circuit and hydraulic control logic inside the pump body 104 and the flow controller 107 can be implemented by those skilled in the art using existing PLC control and conventional hydraulic circuits. The specific internal structure is a well-known technology in the field and will not be described in detail here.

[0040] In a preferred embodiment, to achieve rapid clamping and release of the abutment plate 202, the adjustable clamping mechanism includes a locking ring 207, a first clamping plate 210, a second clamping plate 211, a lever plate 204, a second sleeve 213, a connecting plate 205, a connecting plate shaft 208, and a first sleeve 212. The locking ring 207 is arranged around the outer wall of the abutment plate 202, and the first clamping plate 210 and the second clamping plate 211 are arranged opposite to each other to clamp the outer wall of the abutment plate 202. The first clamping plate 210 and the locking ring 207 are rotatably connected by the first sleeve 212, and the second clamping plate 211 and the locking ring 207 are connected by the connecting plate shaft 204. 08 achieves a rotating connection. The lever plate 204 is rotatably connected to the side of the locking ring 207. The second sleeve 213 is rotatably connected to one end of the lever plate 204. One end of the connecting plate 205 is rotatably connected to the second sleeve 213. The other end of the connecting plate 205 is rotatably connected to the other side of the locking ring 207 through the connecting plate rotating shaft 208. The first sleeve 212 is rotatably connected between the other side of the locking ring 207 and the first clamping plate 210. The lever plate 204 drives the first clamping plate 210 and the second clamping plate 211 to tighten or open synchronously through the linkage mechanism formed by the second sleeve 213, the connecting plate 205, the connecting plate rotating shaft 208 and the first sleeve 212.

[0041] As another preferred embodiment, in order to balance the air pressure inside the splash shield 201 during filling, the splash shield 201 is also provided with a pressure relief hole 203, which is located at the top of the splash shield 201 to ensure that the internal air can be smoothly discharged during the filling process.

[0042] In another preferred embodiment, in order to reliably fix the control plate 303, the locking mechanism includes a locking knob 304 and a locking groove 305. The locking knob 304 is disposed above the support plate 306, and the locking groove 305 is disposed on the side of the control plate 303. The locking knob 304 and the locking groove 305 are locked by threaded engagement. Tightening the locking knob 304 can firmly fix the control plate 303 at any position of the slide groove 307.

[0043] As another preferred embodiment, in order to enhance the positioning stability of the container, the positioning mechanism 3 also includes a baffle 301, which is located behind the positioning arc plate 302 and is fixedly connected to the support plate 306 to provide rearward support and limit the container.

[0044] As another preferred embodiment, in order to adapt to the bottle openings of different sizes, the water outlet 209 is a detachable structure. The water outlet 209 is detachably connected to the bottom of the water injector 105 by means of threads or buckles, which makes it easy for operators to quickly replace it.

[0045] As another preferred embodiment, for ease of operation and monitoring, the control screen 102 in the host 101 is used to display filling parameters and receive operation instructions. Operators can set filling volume, flow rate, etc. through the control screen 102.

[0046] As another preferred embodiment, in order to construct a complete liquid delivery path, the water pipe 106 connects the bottom of the liquid tank 103, the inlet of the pump body 104, the inlet of the flow controller 107, and the inlet of the water injector 105, ensuring that the liquid can flow smoothly from the liquid tank 103 to the water injector 105.

[0047] Working principle: When preparing for filling operation, first place the container to be filled on the support plate 306 of the positioning mechanism 3, push the control plate 303 to slide along the slide groove 307, so that the positioning arc plate 302 fits against the outer wall of the container to determine the position of the container, and then tighten the locking knob 304. The locking knob 304 enters the locking groove 305 on the side of the control plate 303 through the thread engagement, and firmly locks the position of the control plate 303. With the rear limit of the baffle 301, it prevents the container from shifting in subsequent operations.

[0048] Once the container is positioned, the operating lever 204 is used to fix the splash guard 2. The rotation of the lever 204 drives the second sleeve 213 to move, which in turn pulls the connecting plate shaft 208 through the connecting plate 205. At the same time, the linkage structure drives the first sleeve 212 to move, so that the first clamping plate 210 and the second clamping plate 211 rotate relative to each other around the clamping plate shaft 206 and tighten inward. The first clamping plate 210 and the second clamping plate 211 tightly clamp the outer wall of the abutment plate 202, thereby stably fixing the splash guard 201 sleeved on the outside of the abutment plate 202 onto the water outlet 209 and covering the container mouth.

[0049] When the filling program is started, the control panel 102 issues a command, and the pump body 104 draws liquid from the liquid tank 103 through the water pipe 106. After the liquid is accurately measured by the flow controller 107, it is injected into the container through the water injector 105 and the water outlet 209. During this process, the splash guard 201 physically blocks the splashing of liquid, and the pressure relief hole 203 balances the air pressure inside and outside the splash guard 201. After filling is completed, the damper 204 can be released to release the damper 202 and the splash guard 201. The control panel 303 can be moved to remove the container by loosening the locking knob 304.
