Description

Technical Field

[0001] The invention belongs to the technical field of etching foil production equipment, and in particular relates to a quantitative feeding device for etching foil production and processing. Background Art

[0002] Electrode foil includes corrosion foil and chemical foil, which is a key basic material for the production of aluminum electrolytic capacitors. It is used to carry electric charge and together with the electrolyte, it accounts for 30%-70% of the production cost of aluminum electrolytic capacitors (it varies with the size of the capacitor). As an important component of aluminum electrolytic capacitors, electrode foil has broad application prospects in communication products, computers, and home appliance industries. In the production process of electrode foil, the corrosion and chemical processes require the use of a large amount of cleaning liquid to clean the surface of the electrode foil to remove the corrosion acid, chemical solution and aluminum powder impurities remaining on the surface. When performing operations such as immersion, in order to improve efficiency, it is often necessary to add some high-consumption powder materials. The uniformity of addition and the content of material components in the immersion box (1) have a great influence on production efficiency. Therefore, a device suitable for adding powder materials to the immersion box (1) is required.

[0003] For this purpose, a utility model patent with announcement number CN215047046U discloses a quantitative feeding device for corrosion foil production, including a hopper, a quantitative box and a bulk material mechanism. The hopper is arranged above the quantitative box for continuously adding materials into the quantitative box, and the bulk material mechanism is arranged below the quantitative box for uniformly adding the materials weighed by the quantitative box to the production equipment. A metering tray is installed inside the quantitative box through a bracket, and a weighing sensor for weighing the metering tray is also arranged inside the quantitative box. A lever for exporting the material on the metering tray is installed in the quantitative box, and the material-discharging motor is connected to the lever through a transmission shaft to drive the lever to move. The device has a simple structural principle and low equipment cost, and is of great help to the corrosion foil production.

[0004] It relies closely on a weighing sensor to determine the amount of powdered material added. However, in actual use, the amount of material added is related to the conveying speed of the corrosion foil and the capacity of the cleaning liquid in the corrosion foil. The faster the conveying speed of the corrosion foil, the more material is required. The more cleaning liquid in the corrosion foil, the more material is required. Therefore, it is not applicable to only rely on fixed weight to determine the amount of material added, which will affect the cleaning effect of the corrosion foil. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art, solve or at least alleviate the problem that the existing feeding device is not completely suitable for cleaning corrosion foil, and provide a quantitative feeding device for the production and processing of corrosion foil.

[0010] The floating block is longitudinally slidably arranged in the immersion box and floats on the liquid surface of the cleaning liquid in the immersion box. The floating block drives the position of the bottom plate in the feeding trough. When the floating block rises or falls, the bottom plate moves horizontally toward the outside or inside of the feeding trough.

[0011] In order to further realize the present invention, the following technical solutions may be preferably selected:

[0012] Preferably, a plurality of immersion sections are arranged in the immersion box along its length direction, and the corrosion foil in the immersion section is arranged in a V shape. There are two cleaning rollers in each immersion section, and the two cleaning rollers are respectively rolled and fitted on the upper sides of the two inclined sections of the V shape of the corrosion foil, and the cleaning rollers are driven to rotate when the corrosion foil is transported.

[0016] Preferably, the feed roller is in the shape of a hollow circular tube, the depth direction of the feed groove is arranged along the radial direction of the feed roller, and the inner and outer ends of the feed groove are respectively connected to the circumferential inner wall and the circumferential outer wall of the feed roller;

[0017] Preferably, an adjustment mechanism is provided in the feed roller, and the adjustment mechanism includes two positioning nodes and several groups of adjustment groups. The two positioning nodes are axially slidably arranged in the feed roller, and the two positioning nodes move synchronously in opposite directions.

The adjustment group includes two adjustment rods arranged in an X shape, the middle parts of the two adjustment rods are hinged to each other, the inner ends of the two adjustment rods are respectively hinged to the two positioning nodes, and the outer ends of the two adjustment rods are respectively hinged to both sides of the bottom plate.

[0022] Through the above technical solution, the beneficial effects of the present invention are:

[0023] The material in the hopper falls into the feeding trough on the upper side of the feeding roller. When the feeding roller rotates, the material in the feeding trough is added to the immersion box. The feeding roller is connected to the cleaning roller by transmission. The faster the corrosion foil is conveyed, the faster the feeding roller rotates, which increases the frequency of adding materials to the feeding roller. The floating block floats on the liquid surface of the cleaning liquid in the immersion box. When there is more cleaning liquid, the floating block rises with the liquid surface, the bottom plate in the feeding trough moves inward, and the volume of the feeding trough increases, thereby increasing the feeding amount of the feeding roller. The two sets of actions cooperate with each other to match the amount of material added with the conveying speed of the corrosion foil and the capacity of the cleaning liquid in the corrosion foil, so that the amount of material added can better meet the cleaning needs of the corrosion foil and achieve better cleaning effects.

[0041] The following will be combined with the drawings in the embodiments of the invention to clearly and completely describe the technical solutions in the embodiments of the invention. Obviously, the described embodiments are only part of the embodiments of the invention, not all of the embodiments. Based on the embodiments of the invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the invention.

[0042] Embodiment 1:

[0043] like Figure 1-Figure 15 As shown, a quantitative feeding device for etching foil production and processing is provided, the feeding device is arranged above a immersion box 1, a cleaning roller 2 is arranged in the immersion box 1, and the cleaning roller 2 is attached to the etching foil conveyed in the immersion box 1, and is characterized in that the feeding device includes a feeding hopper 3, a feeding roller 4 and a floating block 5;

[0044] The feeding hopper 3 is in the shape of a long strip arranged along the width direction of the immersion tank 1. The feeding hopper 3 is fixedly arranged above the immersion tank 1 and its longitudinal section is in the shape of a trapezoid with a larger top and a smaller bottom.

[0045] The feed roller 4 is rotatably arranged at the lower opening of the feeding hopper 3, the outer circumferential wall of the feed roller 4 is sealed and rotatably fitted with the inner wall of the feeding hopper 3, the feed roller 4 is transmission-connected with the cleaning roller 2, the cleaning roller 2 drives the feed roller 4 to rotate, a plurality of feed troughs are arranged in a circumferential array of the feed roller 4, a bottom plate 6 is arranged in the feed trough, the bottom plate 6 is sealed and slidable along the depth direction of the feed trough, and the volume of the feed trough is controlled by the position of the bottom plate 6;

[0046] The floating block 5 is longitudinally slidably arranged in the immersion box 1 and floats on the liquid surface of the cleaning liquid in the immersion box 1. The floating block 5 drives the position of the bottom plate 6 in the feeding trough. When the floating block 5 rises or falls, the bottom plate 6 moves horizontally toward the outside or inside of the feeding trough.

[0047] In order to achieve better cleaning effect and facilitate the recycling of cleaning liquid at different stages, a plurality of immersion sections are arranged in the immersion box 1 along its length direction. The corrosion foil in the immersion section is arranged in a V shape. There are two cleaning rollers 2 in each immersion section. The two cleaning rollers 2 are respectively rolled and fitted on the upper sides of the two inclined sections of the V-shape of the corrosion foil. The cleaning rollers 2 are driven to rotate when the corrosion foil is transported. The number of feeding devices is equal to that of the immersion sections and they are arranged one by one.

[0048] In order to ensure that the cleaning roller 2 can rotate with the conveying of the etching foil and drive the feeding roller 4 to rotate, a cleaning positioning rod 7 is arranged between the two cleaning rollers 2, and the two cleaning rollers 2 are both rotatably arranged on the cleaning positioning rod 7, and the cleaning positioning rod 7 is longitudinally slidably arranged on the immersion box 1. A spring is arranged between the cleaning positioning rod 7 and the immersion box 1, and the spring drives the cleaning positioning rod 7 to translate downward;

[0049] Both ends of the cleaning roller 2 are fixedly sleeved with driving wheels, and both ends of the feeding roller 4 extend outwardly from the feeding hopper 3 and are fixedly sleeved with driven wheels, which are connected to the driving wheel through a belt.

[0050] In order to optimize the product structure, in this embodiment, the feed roller 4 is in the shape of a hollow circular tube, the depth direction of the feed trough is arranged along the radial direction of the feed roller 4, and the inner and outer ends of the feed trough are respectively connected to the circumferential inner wall and the circumferential outer wall of the feed roller 4.

[0051] An adjustment mechanism is provided in the feed roller 4, and the adjustment mechanism includes two positioning nodes 8 and several groups of adjustment groups. The two positioning nodes 8 are both axially slidably provided in the feed roller 4, and the two positioning nodes 8 move synchronously in opposite directions. The number of adjustment groups is equal to that of the feed trough and they are provided one by one. The adjustment group includes two adjustment rods 9 provided in an X shape, and the middle parts of the two adjustment rods 9 are hinged to each other. The inner ends of the two adjustment rods 9 are respectively hinged to the two positioning nodes 8, and the outer ends of the two adjustment rods 9 are respectively hinged to the two sides of the bottom plate 6. The adjustment rod 9 passes through the inner end opening of the feed trough, so that the positioning node 8 rotates with the feed roller 4.

[0052] In order to facilitate the adjustment of the relative positions of the two positioning nodes 8, an adjusting shaft 10 is coaxially arranged in the feeding roller 4. The adjusting shaft 10 is rotatably arranged on the feeding roller 4. The two positioning nodes 8 both rotate and axially slide on the adjusting shaft 10. The adjusting shaft 10 drives the two positioning nodes 8 to translate synchronously in opposite directions. The positioning nodes 8 rotate synchronously with the feeding roller 4. The adjustment mechanism also includes a positioning sleeve 11. The positioning sleeve 11 is axially slidably arranged in the feeding roller 4 and threadedly fitted on the adjusting shaft 10. One end of the positioning sleeve 11 is rotatably arranged on one of the positioning nodes 8.

[0053] In order to enable the positioning sleeve 11 to translate with the rotation of the adjusting shaft 10, the adjusting mechanism also includes a guide sleeve 12, which is fixedly arranged on the immersion box 1 and rotatably fitted in the feeding roller 4. The inner wall cross-section of the guide sleeve 12 is a regular polygon, and the outer wall cross-section of one end of the positioning sleeve 11 is a regular polygon and is axially slidably fitted in the guide sleeve 12.

[0054] In order to further optimize the product structure, the adjusting shaft 10 can rotate with the rise and fall of the floating block 5. One end of the adjusting shaft 10 extends outward from the feed roller 4 and is fixedly sleeved on the driven gear. A rack is vertically arranged above the floating block 5, and the rack is transmission-connected to the driven gear.

[0055] The material in the hopper 3 falls into the feeding trough on the upper side of the feeding roller 4. When the feeding roller 4 rotates, the material in the feeding trough is added to the immersion tank 1. The feeding roller 4 is connected to the cleaning roller 2 by transmission. The faster the corrosion foil is conveyed, the faster the rotation speed of the feeding roller 4 increases, so that the frequency of adding materials to the feeding roller 4 increases.

[0056] The float 5 floats on the liquid surface of the cleaning liquid in the immersion box 1. When the cleaning liquid is large, the float 5 rises with the liquid surface to drive the adjusting shaft 10 to rotate, and the positioning sleeve 11 translates axially along the adjusting shaft 10, so that the two positioning nodes 8 move outward synchronously, the angle between the positioning rod and the positioning node 8 decreases, the bottom plate 6 in the feeding trough translates inward, and the volume of the feeding trough increases, thereby increasing the feeding amount of the feeding roller 4.

[0057] The two sets of actions cooperate with each other to match the amount of material added with the conveying speed of the corrosion foil and the capacity of the cleaning liquid in the corrosion foil, so that the amount of material added can better meet the cleaning needs of the corrosion foil and achieve better cleaning effect.

[0058] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
