Description

Technical Field

[0001] This invention relates to the field of iron cover cleaning technology, specifically to an online cleaning device for stainless steel iron covers. Background Technology

[0002] In the production of bottled food, the caps need to be sealed quickly after filling. Usually, a stainless steel cap is used to seal the glass bottle. Generally speaking, for lower-priced canned fruits and canned bean paste, the stainless steel caps are not cleaned before sealing. However, for high-value foods such as bird's nest, the stainless steel caps need to be cleaned before sealing in order to avoid affecting the taste and meet the high hygiene requirements.

[0003] Due to the lightweight and wear-resistant properties of PET plastic caps, existing online cleaning devices are widely used for PET plastic caps. However, stainless steel caps are heavier and are prone to paint chipping after severe impacts. Therefore, the cleaning method for stainless steel caps is mostly immersion cleaning to remove oil or dust and other impurities. However, this cleaning method is also prone to secondary contamination when manually or automatically removed and transferred. In addition, due to the limitations of the immersion cleaning method, the cleaning effect is not as good as that of online cleaning devices. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an online cleaning device for stainless steel covers, which can effectively solve the problem of how to improve the cleaning effect of stainless steel covers in the existing technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This invention provides an online cleaning device for stainless steel covers, including a cleaning chamber, a cover slide rail, and a water tank. The cover slide rail is composed of multiple slide rods and conforms to the size specifications of the stainless steel cover. The stainless steel cover enters the cleaning chamber through the cover slide rail with the cover opening facing down. The device also includes a water spray pipe, a fan-shaped nozzle, and a gas connecting pipe.

[0007] A water pump is installed on the outside of the water tank, and the input end of the water pump extends into the water tank. The output end of the water pump is connected to the spray pipe. The spray pipe has a horizontal pipe and multiple fan-shaped nozzles are inclinedly connected below the horizontal pipe. The fan-shaped nozzles are distributed above and below the iron cover slide rail. The inclined fan-shaped nozzles generate lateral impact on the stainless steel cover, pushing the stainless steel cover to move while cleaning.

[0008] The gas connecting pipe is installed at the bottom of the cleaning chamber, and multiple upwardly distributed air nozzles are fixedly installed on the top of the gas connecting pipe. The air nozzles have the same spraying tendency as the fan-shaped nozzles, and while spraying air to remove water from the stainless steel cover, they also push the stainless steel cover to move.

[0009] The water tank is equipped with multiple sets of heating tubes to heat the RO water in the tank and maintain the water temperature at 70℃.

[0010] Furthermore, the iron cover slide rail is divided into two groups, and the horizontal pipe portion of the water spray pipe is located above and below the two groups of iron cover slide rails respectively, and the gas connecting pipe is distributed directly below the iron cover slide rail.

[0011] Furthermore, the cleaning chamber has a horizontal plate that divides the interior space into a water washing section and an air blowing section. The water spray pipe is located in the water washing section, and the bottom of the water spray pipe is connected to the water tank via a water inlet pipe. The bottom plate of the cleaning chamber is fixedly connected to a return pipe, and a filter is installed on the return pipe.

[0012] Furthermore, a sidewall cleaning assembly is provided on the outer side of the iron cover slide rail, and the sidewall cleaning assembly is located in the cleaning chamber. The sidewall cleaning assembly includes a limiting plate on both sides of the iron cover slide rail and a fixing frame fixedly installed on the limiting plate and the outer side of the iron cover slide rail. The limiting plate restricts the left and right position of the stainless steel cover.

[0013] Furthermore, a rubber plate is embedded and fixedly installed in one of the limiting plates, and an L-shaped spray plate is embedded and fixedly installed in the limiting plate on the other side. The vertical part of the L-shaped spray plate is flush with the limiting plate and is distributed correspondingly to the rubber plate. The vertical part of the L-shaped spray plate has multiple spray grooves at an angle. A tube is installed through one side of the L-shaped spray plate and extends to the outside of the cleaning chamber to provide hydraulic pressure to the spray grooves.

[0014] Furthermore, the horizontal portion of the L-shaped spray plate is flush with the top of the iron cover slide rail below, and multiple spray nozzles are embedded and fixedly installed in the horizontal portion of the L-shaped spray plate. The spray nozzles are directed upwards to spray liquid onto the inner edge of the stainless steel cover opening.

[0015] Furthermore, a scraping and fluid replenishment assembly is installed on the top of the limiting plate. The scraping and fluid replenishment assembly includes a brush that is perpendicular to the slide rail of the iron cover and is used to clean the top of the stainless steel cover.

[0016] Furthermore, the scraping and replenishing component also includes two support frames fixedly installed on the top of the limiting plate or the top of the L-shaped spray plate. A fixed shaft is fixedly connected between the two support frames. Two V-shaped connecting frames are rotatably connected to the fixed shaft. Two brushes are respectively connected to the two ends of the V-shaped connecting frames. The V-shaped connecting frames are located directly above the iron cover slide rail to avoid obstructing the spray of the fan-shaped nozzle.

[0017] Furthermore, a liquid container is fixedly connected to the end of the V-shaped connecting frame, and a liquid replenishment pipe is connected between the liquid containers. A movable nozzle is slidably inserted into the liquid container, and a nozzle cover is slidably fitted onto the movable nozzle. A fixing head is fixedly connected to the end of the nozzle cover. The fixing head is fixedly installed on the top of the brush and is slidably inserted into the V-shaped connecting frame through multiple sliding rods. The nozzle cover and the side plate of the movable nozzle are provided with spray holes. Two spray holes on both sides are distributed opposite to the stainless steel cover inside the iron cover slide rail.

[0018] The technical solution provided by this invention has the following advantages compared with the known prior art:

[0019] 1. This invention employs a cleaning device composed of a cleaning chamber, a fan-shaped nozzle, and an air jet nozzle to clean both the top and bottom surfaces of a stainless steel cover. The air jet nozzle removes water from the bottom of the stainless steel cover, achieving a good cleaning effect. In conjunction with the side wall cleaning component, it can help clean the sides of the stainless steel cover. At the same time, the side spraying liquid channel allows the stainless steel cover to rotate, helping to clean all parts of the stainless steel cover.

[0020] 2. This invention employs a scraping and replenishing component, using a brush to clean the top of the stainless steel cap and replenishing the top of the stainless steel cap with cleaning fluid to help remove grease from the top of the stainless steel cap, improving the cleaning effect on grease. In conjunction with two brushes forming a lever, the stainless steel cap is tilted, and with the spray nozzle, the edge area inside the opening of the stainless steel cap is cleaned to complete the cleaning work.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0036] The present invention will be further described below with reference to embodiments.

[0037] Reference Figures 1 to 12Example: An online cleaning device for stainless steel covers includes a cleaning chamber 1, a cover slide rail 2 and a water tank 3, a water spray pipe 6, a fan-shaped nozzle 7 and a gas connecting pipe 8. The cover slide rail 2 is composed of multiple slide rods and conforms to the size specifications of the stainless steel cover. The stainless steel cover enters the cleaning chamber 1 through the cover slide rail 2 with the cover opening facing down.

[0038] A water pump is installed on the outside of the water tank 3, and the input end of the water pump extends into the water tank 3. The output end of the water pump is connected to the spray pipe 6. The spray pipe 6 has a horizontal pipe and multiple fan-shaped nozzles 7 are inclinedly connected below the horizontal pipe. The fan-shaped nozzles 7 are distributed above and below the iron cover slide rail 2. The inclined fan-shaped nozzles 7 generate lateral impact on the stainless steel cover, and push the stainless steel cover to move while cleaning.

[0039] The gas connecting pipe 8 is installed at the bottom of the cleaning chamber 1. Multiple upwardly distributed air nozzles 9 are fixedly installed on the top of the gas connecting pipe 8. The air nozzles 9 have the same spraying tendency as the fan-shaped nozzles 7. While spraying water onto the stainless steel cover, they also push the stainless steel cover to move.

[0040] Multiple sets of heating tubes 12 are installed inside the water tank 3 to heat the RO water in the water tank 3 and maintain the water temperature at 70℃. The iron cover slide rail 2 is divided into two groups, and the horizontal pipe part of the spray pipe 6 is located above and below the two sets of iron cover slide rail 2 respectively. The gas connecting pipe 8 is distributed directly below the iron cover slide rail 2.

[0041] The cleaning chamber 1 has a horizontal plate that divides the space inside the cleaning chamber 1 into a water washing section and an air blowing section. The water spray pipe 6 is located in the water washing section, and the bottom of the water spray pipe 6 is connected to the water tank 3 by a water inlet pipe 4. The bottom plate of the cleaning chamber 1 is fixedly connected to a return pipe 5, and a filter 13 is installed on the return pipe 5.

[0042] The stainless steel cover is conveyed to the cover slide rail 2 by the cover sorting machine. The stainless steel cover slides down into the cleaning chamber 1 by the height difference. Alternatively, the cover slide rail 2 can be blown into the cleaning chamber 1 by airflow. The cleaning chamber 1 is divided into two spaces by a horizontal partition. When the stainless steel cover enters the cleaning chamber 1, it is first washed with water and then blown by low-pressure airflow to remove the water from the stainless steel cover.

[0043] The water tank 3 is heated by the heating pipe 12 to about 70°C. Then, the water in the water tank 3 is pumped through the water inlet pipe 4 to the spray pipe 6. The fan-shaped nozzles 7 on the spray pipe 6 spray the warm water onto the stainless steel cover. The fan-shaped nozzles 7 distributed vertically can wash the stainless steel cover from top to bottom at the same time. With the warm water, the grease and debris on the stainless steel cover can be cleaned well. The fan-shaped nozzles 7 are also inclined to provide force for the stainless steel cover to slide in the cover slide rail 2 while being rinsed.

[0044] Water that falls during the cleaning process flows back into the water tank 3 through the return pipe 5 at the bottom of the cleaning chamber 1. After passing through the filter 13 on the return pipe 5, the water is filtered and then flows back into the water tank 3 to help the RO water be recycled. RO water is high-purity water obtained through reverse osmosis technology. Its core principle is to selectively filter water molecules under high pressure using a semi-permeable membrane. It can remove more than 90% of dissolved solids, heavy metals, organic matter, and microorganisms and other impurities in the water, and has high purity. Therefore, it can be used as a good cleaning water. After being filtered by the filter 13, it can be recycled.

[0045] After the water washing is completed, the stainless steel cover slides to the air blowing part under the impact of the fan-shaped nozzle 7. The gas connecting pipe 8 is connected to an external air source, and the air jet nozzle 9 blows air under the stainless steel cover to clean up the water under the stainless steel cover. Under the action of low-pressure airflow, the area under the stainless steel cover is dried.

[0046] Specifically, a side wall cleaning assembly 11 is provided on the outside of the iron cover slide rail 2, and the side wall cleaning assembly 11 is located in the cleaning chamber 1. The side wall cleaning assembly 11 includes a limiting plate 1101 on both sides of the iron cover slide rail 2 and a fixing frame 1102 fixedly installed on the limiting plate 1101 and the outside of the iron cover slide rail 2. The limiting plate 1101 restricts the left and right positions of the stainless steel cover.

[0047] A rubber plate 1103 is embedded and fixedly installed on one side of the limiting plate 1101, and an L-shaped spray plate 1104 is embedded and fixedly installed in the limiting plate 1101 on the other side. The vertical part of the L-shaped spray plate 1104 is flush with the limiting plate 1101 and is distributed correspondingly to the rubber plate 1103. The vertical part of the L-shaped spray plate 1104 is inclined to have multiple spray grooves 1106. A tube 1107 is installed through one side of the L-shaped spray plate 1104. The tube 1107 extends to the outside of the cleaning chamber 1 to provide hydraulic pressure to the spray grooves 1106.

[0048] An external limiting plate 1101 acts as a baffle, restricting the left and right position of the stainless steel cover during the cleaning process. Inside the washing section, a rubber plate 1103 is embedded in a portion of the length of the limiting plate 1101, and the rubber plate 1103 is flush with the limiting plate 1101. The vertical portion of the L-shaped spray plate 1104, opposite the rubber plate 1103, is also flush with the limiting plate 1101. The L-shaped spray plate 1104 is externally connected to a pipe 1107, utilizing an inclined spray... The liquid tank 1106 rinses the side wall of the stainless steel cover. Simultaneously, the direction of action of the liquid tank 1106 on the stainless steel cover is the same as that of the fan-shaped nozzle 7, thus not hindering the movement of the stainless steel cover. Furthermore, when liquid is sprayed from the liquid tank 1106, it exerts a force on the side wall of the stainless steel cover, forcing it into contact with the rubber plate 1103, and simultaneously generating a force that causes the stainless steel cover to rotate. The rubber plate 1103 then cushions the stainless steel cover. The spray pattern prevents the stainless steel cover from colliding with objects on the side when the spray tank 1106 impacts it, protecting the paint on the outside of the stainless steel cover. Simultaneously, the rubber plate 1103 provides friction to the sidewalls of the stainless steel cover. When the spray tank 1106 impacts the stainless steel cover at an angle, the cover will adhere tightly to the rubber plate 1103. Under the tilted impact force provided by the spray tank 1106, the stainless steel cover will rotate within the cover slide rail 2. This allows the area around the stainless steel cover to be cleaned by the spray tank 1106 on one side without causing significant shaking, reducing the risk of collisions. Correspondingly, during the rotation of the stainless steel cover, it is also rinsed by the fan-shaped nozzles 7, allowing it to be cleaned while rotating. The spray tank 1106, working in tandem with the cleaning action, prevents the cleaned debris from adhering to the sidewalls, achieving a better cleaning effect.

[0049] Specifically, the horizontal part of the L-shaped spray plate 1104 is flush with the top of the iron cover slide rail 2 below, and multiple spray nozzles 1105 are fixedly installed in the horizontal part of the L-shaped spray plate 1104. The spray nozzles 1105 are directed upwards and spray liquid onto the inner edge of the stainless steel cover opening.

[0050] Because the stainless steel cap is formed by stamping during the production process, and the opening of the cap has many indentations to fit the can body, the spray nozzle 1105 located below the cap opening can effectively rinse the inner edge of the cap opening. Correspondingly, it forces one side of the stainless steel cap to be subjected to an upward impact force, causing the stainless steel cap to lose contact with the cap slide rail 2 below. This also reduces the friction between the stainless steel cap and the cap slide rail 2 during the dual actions of sliding and rotating, and makes the sliding and rotating process of the stainless steel cap smoother.

[0051] Correspondingly, the liquid supplied by the insertion tube 1107 to the L-shaped spray plate 1104 can be RO water from the water tank 3 or a cleaning solution specifically for cleaning grease. The port connected to the insertion tube 1107 can be changed for different stainless steel cap products.

[0052] Specifically, a scraping and replenishing fluid assembly 10 is installed on the top of the limiting plate 1101. The scraping and replenishing fluid assembly 10 includes a brush 103 that is perpendicular to the iron cover slide rail 2 and is used to clean the top of the stainless steel cover.

[0053] During the movement and rotation of the stainless steel cover, it passes over the brush 103 located above the cover slide rail 2, and the brush 103 scrapes the top of the stainless steel cover to help remove debris from the top of the stainless steel cover and prevent secondary adhesion of debris. At the same time, the brush 103 located above makes contact with the top of the stainless steel cover with its bristles, which can reduce the collision between the stainless steel cover and the upper cover slide rail 2 when the stainless steel cover is pushed upward by the impact of the spray nozzle 1105.

[0054] Specifically, the scraping and replenishing liquid assembly 10 also includes two support frames 101 fixedly installed on the top of the limiting plate 1101 or the top of the L-shaped spray plate 1104. A fixed shaft 102 is fixedly connected between the two support frames 101. Two V-shaped connecting frames 104 are rotatably connected to the fixed shaft 102. Two brushes 103 are connected to the two ends of the V-shaped connecting frames 104 respectively. The V-shaped connecting frames 104 are located directly above the iron cover slide rail 2 to avoid blocking the spray of the fan-shaped nozzle 7.

[0055] While the brush 103 is scraping the top of the stainless steel cover, the stainless steel cover will intermittently and unevenly move upward under the impact force generated by the spray nozzle 1105. This movement will cause the stainless steel cover to come into contact with the bristles of the brush 103, and may also squeeze the brush 103. The brushes 103 are arranged in pairs, and each pair of brushes 103 is connected by two V-shaped connecting brackets 104. Since the fixed shaft 102 is located in the middle of the V-shaped connecting brackets 104, the two brushes 103 are connected in the V-shape. The frame 104 forms a balanced lever state under the connection. When the stainless steel cover is subjected to an uneven upward impact force, it will squeeze one of the brushes 103 and cause the other brush 103 in the same group to move downward, pressing the rest of the stainless steel cover so that it cannot move upward. At this time, the stainless steel cover will tilt under the uneven upward impact force, which allows the liquid sprayed from the nozzle 1105 to clean the inside of the stainless steel cover at different angles, helping to clean away grease or other debris from various parts of the stainless steel cover.

[0056] Specifically, a liquid container 108 is fixedly connected to the end of the V-shaped connecting frame 104. A replenishment pipe 107 is connected between the liquid containers 108. A movable nozzle 109 is slidably inserted inside the liquid container 108. A nozzle cover 1010 is slidably sleeved outside the movable nozzle 109. A fixing head 105 is fixedly connected to the end of the nozzle cover 1010. The fixing head 105 is fixedly installed on the top of the brush 103 and is slidably inserted into the V-shaped connecting frame 104 through multiple sliding rods. The nozzle cover 1010 and the side plate of the movable nozzle 109 are provided with spray holes 106. The two spray holes 106 on both sides are distributed opposite to the stainless steel cover inside the iron cover slide rail 2.

[0057] When one of the brushes 103 is subjected to an upward impact, the component between the V-shaped connecting bracket 104 and the fixed head 105 helps to cushion the impact, reducing collisions between the stainless steel cover and the iron cover slide rail 2 or the brush 103 when the stainless steel cover moves upward. When the impact force acts on the brush 103, it will force the nozzle cover 1010 to slide into the movable nozzle 109. The spray hole 106, which is opened on both the movable nozzle 109 and the nozzle cover 1010, will always spray cleaning solution onto the stainless steel cover. As the nozzle cover 1010 slides toward the movable nozzle 109, the diameter of the spray hole 106 decreases, increasing the hydraulic pressure in the liquid container 108 and the movable nozzle 109. This provides resistance to the upward movement of the brush 103, preventing the stainless steel cover from bumping against the air as it moves upward rapidly. Correspondingly, when the stainless steel cover moves upward to its limit, the nozzle cover 1010 completely covers the outside of the movable nozzle 109, and the diameter of the spray hole 106 is reduced to its minimum. At this point, the resistance to the upward movement of the stainless steel cover is at its maximum.

[0058] Each brush 103 in the same group has four liquid containers 108 and four movable nozzles 109. Two movable nozzles 109 on the same brush 103 and the spray holes 106 on the nozzle cover 1010 face the same direction, all towards the larger area of ​​the stainless steel cover. The movable nozzles 109 on another brush 103 and the spray holes 106 on the nozzle cover 1010 face the same direction, also towards the larger area of ​​the stainless steel cover. Cleaning fluid and hydraulic pressure are supplied to the liquid containers 108 via interconnected replenishment pipes 107. During production, the top of the stainless steel cover is located at the part where the mold is demolded, making it more prone to grease buildup. The cleaning fluid sprayed onto the stainless steel cover, combined with the flushing action of the fan-shaped nozzle 7, removes the grease. Simultaneously, the varying orifice diameter of the spray nozzle 106, even with minimal hydraulic pressure changes in the replenishment pipe 107, alters the distance of the ejected liquid flow. This variation in orifice diameter allows for a change in the spray range of the cleaning fluid, ensuring that the side-sprayed cleaning fluid covers a sufficiently large area and guarantees effective degreasing.

[0059] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
