Description

Technical Field

[0001] This utility model relates to the field of tinplate processing technology, and in particular to a tinplate tin-plating device based on corona discharge. Background Technology

[0002] Tinplate processing refers to a series of processes involving tinplate, including cutting, stamping, forming, welding, and surface treatment, to manufacture various products or parts that meet specific needs. Tinplate processing first requires tin plating thin steel sheets to give them good corrosion resistance, weldability, and aesthetics. Corona tin plating equipment utilizes the plasma environment generated by corona discharge to allow tin ions to adhere more evenly and firmly to the tinplate surface, providing high-quality tin-plated sheets for subsequent processing steps.

[0003] Existing corona-based tinplate tinning equipment can only directly transport tinplate without anti-shaking function. If the tinplate shakes, the tinplate will be unevenly distributed on its surface, which may also affect the corona treatment effect, resulting in defects such as uneven tinplate thickness and pitting, and thus affecting the tin plating process. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that tinplate is prone to shaking when it is transported. To this end, we propose a tinplate tinning device based on corona discharge.

[0005] To achieve the above objectives, this application adopts the following technical solution: a corona-based tin-plating device for tinplate, comprising a fixed base, a corona plating mechanism mounted on the top of the fixed base, electrically driven rotating rollers mounted on opposite sides of the fixed base, a connecting frame fixedly connected to the surface of the fixed base, a fixed block mounted at the end of the connecting frame, an adjusting rod slidably connected inside the fixed block, several limiting grooves formed on both sides of the adjusting rod, a handle fixedly connected to the top of the adjusting rod, a contact plate fixedly connected to the bottom of the adjusting rod, sliding grooves formed on both sides inside the fixed block, a sliding rod slidably connected inside the sliding grooves, a push-pull plate fixedly connected to the side of the sliding rod away from the fixed block, a spring slidably connected to the surface of the sliding rod, the side of the spring away from the fixed block fixedly connected to the push-pull plate, and the side of the spring close to the fixed block fixedly connected to the fixed block.

[0006] Preferably, an energy storage spring is fixedly connected to the top of the fixing block, and there are two energy storage springs. The top of the energy storage spring is fixedly connected to the bottom of the handle.

[0007] Preferably, the surface of the adjusting rod is provided with a self-lubricating coating.

[0008] Preferably, the front and rear ends of the fixed block are provided with first sliding grooves, and the front and rear ends of the adjusting rod are fixedly connected with first sliders, and the interior of the first sliding groove is slidably connected to the first slider.

[0009] Preferably, a second sliding groove is provided at both the front and rear ends of the sliding groove, and a second slider is fixedly connected to both the front and rear ends of the sliding rod, with the interior of the second sliding groove slidably connected to the second slider.

[0010] Preferably, the size of the sliding rod is designed to match the inner diameter of the limiting groove.

[0011] Preferably, the contact plate is made of aluminum alloy.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, when workers need to tinplate, the tinplate is placed on an electric rotating roller, and then pulled so that one end of the tinplate is placed on another electric rotating roller. At this point, the push-pull plate is pulled outwards to pull the sliding rod out of the limiting groove, releasing the adjusting rod from its limit. Then, the handle is pushed to make the contact plate press against the tinplate, and the push-pull plate is released. The elastic force of the spring then causes the sliding rod to re-insert into the limiting groove, limiting the contact plate and adjusting the tightness of the tinplate. The electric rotating roller is then started to transport the tinplate. At this point, the corona discharge in the corona tin plating mechanism begins, causing tin ions to accelerate under the electric field, impacting the tinplate surface and gaining electrons to be reduced to metallic tin, thus completing the tin plating process. By adjusting the tightness of the tinplate during use, the tinplate will not vibrate during tin plating, resulting in a more uniform tin plating thickness and reducing the likelihood of defective products, effectively improving tin plating efficiency and quality.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a corona-based tinplate tinning device, including a fixed base 1, a corona tinning mechanism 2 installed at the top of the fixed base 1, electric rotating rollers 3 installed on opposite sides of the fixed base 1, a connecting frame 4 fixedly connected to the surface of the fixed base 1, a fixed block 5 installed at the end of the connecting frame 4, an adjusting rod 6 slidably connected inside the fixed block 5, several limiting grooves 7 opened on both sides of the adjusting rod 6, a handle 8 fixedly connected to the top of the adjusting rod 6, a contact plate 9 fixedly connected to the bottom of the adjusting rod 6, sliding grooves 10 opened on both sides inside the fixed block 5, a sliding rod 11 slidably connected inside the sliding groove 10, a push-pull plate 12 fixedly connected to the side of the sliding rod 11 away from the fixed block 5, a spring 13 slidably connected to the surface of the sliding rod 11, the side of the spring 13 away from the fixed block 5 fixedly connected to the push-pull plate 12, and the side of the spring 13 close to the fixed block 5 fixedly connected to the fixed block 5. When the worker needs to tinplate... At this time, place the tinplate on the electric rotating roller 3, and then pull it so that one end of the tinplate is placed on another electric rotating roller 3. Then, pull the push-pull plate 12 outward to pull the sliding rod 11 out of the limiting groove 7, so that the adjusting rod 6 is released from the limit. Then, push the handle 8 to make the contact plate 9 stick to the tinplate, and then release the push-pull plate 12. At this time, the elastic force of the spring spring 13 will drive the sliding rod 11 to re-insert into the limiting groove 7, so that the contact plate 9 is limited, thus achieving the adjustment of the tightness of the tinplate. Then, the electric rotating roller 3 is started to transport the tinplate. At this time, the corona discharge in the corona tin plating mechanism 2 begins to discharge, causing tin ions to accelerate under the action of the electric field, collide with the surface of the tinplate, and gain electrons on the surface to be reduced to metallic tin, thus achieving the overall tin plating process. By adjusting the tightness of the tinplate transport during use, the tinplate will not shake during the tin plating process, resulting in a more uniform tin plating thickness and less chance of producing defective products, effectively improving the efficiency and effect of tin plating.

[0022] Reference Figure 4As shown in this embodiment: the top of the fixing block 5 is fixedly connected with an energy storage spring 14, and there are two energy storage springs 14. The top of the energy storage spring 14 is fixedly connected to the bottom of the handle 8. With the setting of the energy storage spring 14, after the tinplate is tinned, the adjusting rod 6 is released from the limit. At this time, the tension stored in the energy storage spring 14 will drive the contact plate 9 to quickly return to the initial position, thereby achieving the quick reset of the contact plate 9 after use, which is convenient for the next use and operation of the staff.

[0023] Reference Figure 3 As shown in this embodiment, the surface of the adjusting rod 6 is provided with a self-lubricating coating. By providing a self-lubricating coating on the surface of the adjusting rod 6, the adjusting rod 6 can be adjusted more smoothly during the adjustment process and is less prone to jamming, thereby further improving the convenience and effectiveness of adjustment.

[0024] Reference Figure 5 As shown in this embodiment: the front and rear ends of the fixed block 5 are provided with first sliding grooves 15, and the front and rear ends of the adjusting rod 6 are fixedly connected with first sliders 16. The interior of the first sliding groove 15 is slidably connected to the first slider 16. Through the setting of the first sliding groove 15 and the first slider 16, the adjusting rod 6 can form a stable guiding effect during the adjustment process, so that the contact plate 9 will not deviate when it moves, so that it can better provide a limiting effect for the tinplate and improve the use effect.

[0025] Reference Figure 5 As shown in this embodiment: the front end and the rear end of the sliding groove 10 are both provided with a second sliding groove 17, and the front end and the rear end of the sliding rod 11 are both fixedly connected with a second slider 18. The interior of the second sliding groove 17 is slidably connected with the second slider 18. By setting the second sliding groove 17 and the second slider 18, the sliding rod 11 can be more stable when moving inside the sliding groove 10, so that the sliding rod 11 will not move too much, effectively ensuring the stable fixation of the adjusting rod 6.

[0026] Reference Figure 4 As shown in this embodiment, the size of the sliding rod 11 is designed to match the inner diameter of the limiting groove 7. With the sliding rod 11 and the limiting groove 7 matched, when the sliding rod 11 is inserted into the limiting groove 7, there will be no shaking or falling off, which makes the contact plate 9 more stable after adjustment and further improves the use effect.

[0027] Reference Figure 3 As shown in this embodiment, the contact plate 9 is made of aluminum alloy. By using aluminum alloy for the contact plate 9, it will have better wear resistance when in contact with tinplate, thereby effectively improving the service life of the contact plate 9.

[0028] Working principle: When the operator needs to tinplate, the tinplate is placed on the electric rotating roller 3, and then pulled so that one end of the tinplate is placed on another electric rotating roller 3. At this time, the push-pull plate 12 is pulled outward to pull the sliding rod 11 out of the limiting groove 7, so that the adjusting rod 6 is released from the limit. Then, the handle 8 is pushed to make the contact plate 9 press against the tinplate. Then, the push-pull plate 12 is released. At this time, the elastic force of the spring spring 13 will drive the sliding rod 11 to re-insert into the limiting groove 7, so that the contact plate 9 is limited, thereby adjusting the tightness of the tinplate. Then, the electric rotating roller 3 is started to start conveying the tinplate. At this point, the corona discharge in the corona tinning mechanism 2 begins, causing tin ions to accelerate under the influence of the electric field, collide with the tinplate surface, and gain electrons on the surface to be reduced to metallic tin, thus achieving the overall tinning process. By adjusting the tension of the tinplate feed during use, the tinplate can be prevented from shaking during tinning, resulting in a more uniform tinning thickness and reducing the likelihood of defective products, effectively improving tinning efficiency and quality. Through the energy storage spring 14, after the tinplate tinning is completed, the adjusting rod 6 is released from its limit. The stored tension in the energy storage spring 14 then causes the contact plate 9 to quickly pull back. The initial position allows for quick reset of the contact plate 9 after use, facilitating subsequent use and operation by the staff. A self-lubricating coating on the surface of the adjusting rod 6 ensures smoother adjustment, reducing the likelihood of jamming and improving convenience and effectiveness. The first groove 15 and the first slider 16 provide a stable guide for the adjusting rod 6 during adjustment, preventing the contact plate 9 from shifting and better limiting its position on the tinplate, thus enhancing usability. The second groove 17 and... The second slider 18 makes the sliding rod 11 more stable when moving inside the sliding groove 10, thus preventing the sliding rod 11 from moving too much and effectively ensuring the stable fixation of the adjusting rod 6. Through the matching of the sliding rod 11 and the limiting groove 7, when the sliding rod 11 is inserted into the limiting groove 7, there will be no shaking or falling off, thus making the fixed position of the contact plate 9 after adjustment more stable and further improving the use effect. By using the contact plate 9 made of aluminum alloy, it will have better wear resistance when contacting tinplate, thus effectively extending the service life of the contact plate 9.
