Description

Technical Field

[0001] The present invention relates to the technical field of additive addition, and specifically to an additive addition device and an addition method for electrolytic copper foil used in electrolytic copper foil. Background Art

[0002] In the current industrial production process, it is a very necessary step to configure solution products. By adding another additive to a solution and mixing them, the required product can be obtained. Currently, a large amount of manual labor is required in industrial production to perform step operations to ensure that the quality of the product meets the standards.

[0003] In the current process of adding powder additives, the reaction process in the reaction kettle is often slow, and the addition amount of the additive cannot be reacted in time. Secondary monitoring and judgment are still required, and the process is cumbersome, time-consuming and laborious. Secondly, there are also a small number of automatic addition devices that cannot control the amount of additive according to the amount of solvent in the stirring kettle. Manual operation of the device for addition will result in inaccurate addition amount, affecting the internal mixing ratio. And during the mechanical addition process, due to the caking phenomenon inside the additive, the addition amount cannot be accurately controlled, resulting in inaccurate addition amount.

[0004] The existing method for adding additives for electrolytic copper foil is as follows:

[0005] Step 1: Place an appropriate amount of additive in the storage tank connected to the reaction kettle, and manually start the reaction kettle to work. At this time, the solvent flows into the reaction kettle through the pipeline;

[0006] Step 2: When an appropriate amount of solvent enters the reaction kettle, the discharge port of the storage tank is opened to put in the additive. Manually observe the input amount and the remaining amount of the additive according to the additive display on the storage tank. When the internal mixing degree is slow, it is necessary to manually stop the input of the additive. After the internal mixing is completed, open the feed port of the storage tank to continue putting in the additive;

[0007] Step 3: When it is found manually that the additive in the storage tank shows a caking phenomenon, it is necessary to disperse the additive in the storage tank. After dispersion, continue to open the storage tank for the addition operation;

[0008] Step 4: When it is observed manually that the additive has reached the addition amount, perform the operation of closing the feeding of the storage tank to avoid the phenomenon of excessive additive consumption and uneven mixing caused by the need for manual frequent running and observation when multiple devices work together.

[0009] Based on this, the present invention designs an additive addition device and an addition method for electrolytic copper foil used in electrolytic copper foil to solve the above problems. Summary of the Invention

[0010] The object of the present invention is to provide an additive adding device and an adding method for electrolytic copper foil, which drive a rotating block to rotate through the driving action of a driving source, and then drive a force-receiving rotating wheel to rotate and stir through the connection between a sliding rod and an arc spring. At the same time, under the action of the sliding rod sliding on the surface of a conical frame, the conical frame drives a blocking block to open the outlet of the storage bin downward, and the weight is converted into displacement to judge the adding amount, and then the adding amount is converted into displacement, so that when the arc spring is stretched to a corresponding length, the stretching of the arc spring is stopped, thereby adding the additive quantitatively and slowly, and solving the problem of preventing waste of the additive caused by inaccurate adding amount during manual adding.

[0011] To achieve the above object, the present invention provides the following technical solution: An additive adding device for electrolytic copper foil, including a reaction kettle body, a driving source is fixed on the top of the reaction kettle body, a rotating central axis is fixed at the output end of the driving source, and a plurality of rotating blocks with U-shaped grooves on the surface are arranged circumferentially on the rotating central axis. A sliding rod is slidably connected to the surface of the U-shaped groove, and a limiting block slidably connected to the top of the rotating block is fixed circumferentially on the sliding rod. The limiting block limits the sliding rod to prevent the sliding rod from moving in the vertical direction. An arc spring is arranged circumferentially on the sliding rod. One end of the arc spring away from the sliding rod is fixedly connected to the inner wall of a plurality of arc grooves corresponding to the sliding rod on a force-receiving rotating wheel. The arc grooves are arranged as circular arcs away from the axis of the force-receiving rotating wheel. A support block fixed to the inner wall of the reaction kettle body penetrates through the circumference of the force-receiving rotating wheel. The top of the sliding rod is slidably connected to a conical frame with a convex table surface at the bottom. The top of the sliding rod is arranged as an inclined surface the same as the convex table surface of the conical frame. A group of blocking blocks with inclined surfaces at the top are arranged at both ends of the conical frame to block the additive outlet, and the inclined surface at the top is beneficial for the additive to slide down. One side of the blocking block away from the connecting surface of the conical frame is slidably connected to a storage bin fixed to the reaction kettle body. The storage bin is used for storing the additive.

[0012] As a further scheme of the present invention, a direction-changing bevel gear is meshed with the top of the conical frame through a bevel gear. One end of the direction-changing bevel gear away from the conical frame is rotatably connected to a first transmission chain. The surface of the first transmission chain is rotatably connected to a stirring shaft penetrating through the reaction kettle body. The surface of the stirring shaft is rotatably connected to a linkage shaft rotatably connected to the reaction kettle body. A plurality of bevel gear sets rotatably connected to the reaction kettle body are arranged circumferentially on the linkage shaft. A rotating turbine is arranged at the bottom of the bevel gear set. The rotating turbine is used for rotating and dispersing the additive.

[0013] As a further scheme of the present invention, a stirring wheel penetrates through the circumference of the stirring shaft. Both ends of the stirring wheel are rotatably connected to a fixing frame arranged on the inner wall of the reaction kettle body. The stirring wheel is used for dispersing the additive falling from the storage bin.

[0014] As a further solution of the present invention, a cam block is provided at the bottom of the rotating turbine. A reciprocating plate that is slidably connected to the rotating turbine is slidably connected to the surface of the cam block. Moreover, the bottom of the reciprocating plate is slidably connected to a fixing plate provided on the outer wall of the reaction kettle body. A compression spring connected to the fixing plate is provided on the side of the reciprocating plate away from the sliding connection with the cam block.

[0015] As a further solution of the present invention, the top of the reciprocating plate is slidably connected to the bottom of the storage bin.

[0016] As a further solution of the present invention, a group of material blocking inclined blocks located below the stirring wheel are provided on the inner wall of the reaction kettle body. The material blocking inclined blocks are used for guiding the falling additive.

[0017] As a further solution of the present invention, rotating convex platforms are circumferentially provided on the force receiving runner. Stirring fan blades are provided at the bottom of the force receiving runner and are close to the bottom of the reaction kettle body below the rotating convex platforms. The rotating convex platforms are used for performing a projectile motion with different starting points on the falling additive, thereby increasing the spraying range of the additive. The stirring fan blades are used for stirring the mixture.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] In the present invention, the rotation of the driving source drives the rotation of the rotating central shaft, and then drives the rotation of the rotating block. The rotation of the rotating block drives the rotation of the force receiving runner through the connection of the sliding rod and the arc spring. The sliding of the sliding rod on the U-shaped groove stretches the arc spring. The sensor is used to detect the stretching degree of the arc spring to determine the addition amount of the additive, and then the addition amount is converted into an additional stretching amount of the arc spring. At the same time, the sliding rod slides on the surface of the conical frame to drive the conical frame to move downward, and then drives the blocking block to move downward through the conical frame to open the material blocking port of the storage bin for feeding. When the arc spring is stretched to the additional stretching amount, the arc spring stops stretching at this time. At this time, the addition amount of the additive is in the required proportion with the solvent, so as to achieve the function of automatically adding the additive in the required proportion to prevent waste caused by the imbalance of the proportion during manual adjustment of the addition.

[0020] In the present invention, the rotation of the rotating central shaft drives the rotation of the direction-changing bevel gear, and then drives the stirring shaft and the linkage shaft to rotate through the first transmission chain and the second transmission chain. The rotation of the linkage shaft drives the rotation of the rotating turbine through the bevel gear set, and then stirs the additive inside the storage bin. Moreover, the additive falling from the storage bin enters the stirring wheel. The stirring wheel rotates driven by the stirring shaft to disperse the additive again by rotation. Then, guided by the material blocking inclined block, it is thrown out from different projectile points along the surface of the rotating convex platform to be mixed with the solvent, so as to achieve the function of automatically dispersing the additive to prevent uneven mixing due to agglomeration.

[0021] In the present invention, the rotation of the rotating turbine drives the cam block to rotate centrifugally. The rotation of the cam block drives the reciprocating plate to reciprocate between the storage bin and the fixed plate, vibrating the additives inside the storage bin, so as to achieve the function of automatically dispersing the additives inside the storage bin to prevent caking.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to Figure 1-9 , the present invention provides a technical solution: an additive adding device for electrolytic copper foil, including a reaction kettle body 1. A driving source 2 is fixed at the top of the reaction kettle body 1. A rotating central axis 3 is fixed at the output end of the driving source 2. A plurality of rotating blocks 4 with U-shaped grooves 5 opened on the surface are arranged circumferentially on the rotating central axis 3. A sliding rod 6 is slidably connected to the surface of the U-shaped groove 5. A limiting block 7 fixedly connected to the top of the rotating block 4 is arranged circumferentially on the sliding rod 6. The limiting block 7 plays a role in limiting the sliding rod 6 to prevent the sliding rod 6 from moving in the vertical direction. An arc spring 8 is arranged circumferentially on the sliding rod 6. One end of the arc spring 8 away from the sliding rod 6 is fixedly connected to the inner wall of a plurality of arc grooves 10 corresponding to the sliding rod 6 opened on a force-bearing runner 9. The arc groove 10 is set as a circular arc away from the axis of the force-bearing runner 9. A support block 11 fixedly connected to the inner wall of the reaction kettle body 1 penetrates through the circumference of the force-bearing runner 9. The top of the sliding rod 6 is slidably connected to a conical frame 12 with a convex table surface at the bottom. The top of the sliding rod 6 is set as an inclined surface the same as the convex table surface of the conical frame 12. A group of material-blocking blocks 13 with inclined surfaces at the top are arranged at both ends of the conical frame 12 for blocking the additive outlet, and the inclined surface at the top is beneficial for the additive to slide down. The side of the material-blocking block 13 away from the connecting surface of the conical frame 12 is slidably connected to a storage bin 14 fixedly connected to the reaction kettle body 1 for storing additives;

[0036] When the device needs to perform reaction work (during the mixing of additives and solvents, the viscosity inside does not change significantly to prevent an increase in resistance during mixing and affecting the addition amount of additives), at this time, the drive source 2 starts to operate. The operation of the drive source 2 drives the rotation shaft 3 to start rotating. The rotation of the rotation shaft 3 drives several rotating blocks 4 to rotate. Furthermore, through the U-shaped groove 5 provided on the surface of the rotating block 4, the sliding rod 6 is driven to slide. The sliding of the sliding rod 6 drives the arc spring 8 to stretch (as Figure 5 shown. From the Figure 5 front view angle, the rotation shaft 3 rotates counterclockwise. At this time, the sliding rod 6 slides away from the axis of the rotation shaft 3 within the U-shaped groove 5). When the pulling force is greater than the resistance received by the lower stirring fan blade 27 during stirring, at this time, the rotating block 4 drives the force-receiving runner 9 to rotate through the sliding rod 6 and the arc spring 8. The rotation of the force-receiving runner 9 drives the stirring fan blade 27 to rotate and stir. At the same time, the movement of the sliding rod 6 away from the axis of the rotation shaft 3 causes the top of the sliding rod 6 to slide along the surface of the conical frame 12 (as Figure 4 shown. From the Figure 4 front view direction, the surface of the conical frame 12 is set as a conical arc). At this time, the sliding of the sliding rod 6 causes the conical frame 12 to move downward, and then drives the material-blocking block 13 to move downward. The downward movement of the material-blocking block 13 opens the discharge port of the storage bin 14 (as Figure 7 shown. From the Figure 7When viewed from the front direction, the discharge port of the storage bin 14 is set to be inclined, which is convenient for the feeding of the additive). At this time, the additive falls from the inside of the storage bin 14 to the bottom of the reaction kettle body 1 to be mixed with the solvent. Since the arc-shaped spring 8 is stretched under tension during the stage when the rotating block 4 drives the force-bearing runner 9 to rotate, and since the mass of the solvent at the bottom of the reaction kettle body 1 is constant at this time, the required stirring force is also constant. At this time, the stretching amount of the arc-shaped spring 8 reflects the amount of the reaction solvent. When the additive is added to the solvent, the total mass at the bottom increases. Since the required rotational force increases, the rotating block 4 has to drive the force-bearing runner 9 to rotate, and the stretching length of the arc-shaped spring 8 will increase, thereby driving the force-bearing runner 9 to continue rotating. The increase in the stretching distance of the arc-shaped spring 8 will cause the distance between the sliding rod 6 and the axis of the rotating shaft 3 to increase. At this time, the conical frame 12 also descends as the sliding rod 6 slides, thereby driving the material-blocking block 13 to descend to increase the size of the discharge port. At this time, the increased falling additive causes the total mass at the bottom of the reaction kettle body 1 to continue to increase, and this repeated movement ensures the slow and uniform addition of the additive, preventing the phenomenon of uneven mixing caused by too fast feeding speed. During the whole process, sensors are used for intermediate control. When the rotating block 4 initially drives the force-bearing runner 9 to rotate, the stretching length of the arc-shaped spring 8 is detected by the sensor, and the amount of the required additive is calculated based on this stretching length. Then, the amount of this additive is converted into the required stretching length for further stretching, so as to control the centrifugal distance of the sliding rod 6. When the stretching distance of the arc-shaped spring 8 reaches the stretching distance configured by the sensor, the arc-shaped spring 8 stops stretching, and then the sliding rod 6 stops centrifugal sliding. After the sliding rod 6 stops centrifugal sliding, the material-blocking block 13 stops descending, thereby achieving automatic quantitative control of the additive, reducing the complexity of manual control, and at the same time avoiding the waste of the additive caused by excessive addition.

[0037] As a further solution of the present invention, the top of the conical frame 12 is meshed with a direction-changing bevel gear 17 through a bevel gear. One end of the direction-changing bevel gear 17 away from the conical frame 12 is rotatably connected to a first transmission chain 18. The surface of the first transmission chain 18 is rotatably connected to a stirring shaft 19 penetrating the reaction kettle body 1. The surface of the stirring shaft 19 is rotatably connected to a linkage shaft 20 rotatably connected to the reaction kettle body 1. A number of bevel gear sets 21 rotatably connected to the reaction kettle body 1 are circumferentially arranged on the linkage shaft 20 (the radius of the bevel gear of the bevel gear set 21 connected to the linkage shaft 20 is larger than the radius of the meshing bevel gear, and the rotation speed is increased by changing the different radii). A rotating turbine 22 is arranged at the bottom of the bevel gear set 21, and the rotating turbine 22 is used for rotating and dispersing the additive;

[0038] At the same time, the rotation of the rotating shaft 3 drives the direction-changing bevel gear 17 to rotate (such as Figure 8As shown, when viewed from the front of 8, the bevel gear 17 is used to change the plane of rotation). At this time, the bevel gear 17 drives the agitating shaft 19 to rotate through the first transmission chain 18, and the rotation of the agitating shaft 19 drives the linkage shaft 20 to rotate through the second transmission chain 29 (as Figure 1 shown, when viewed from the front of 1, the bevel gear 17, the first transmission chain 18, the agitating shaft 19, the second transmission chain 29, and the linkage shaft 20 all use gear chain transmission to prevent slipping during rotation, increase transmission stability, and the linkage shaft 20 is actively connected to the drive source through the first transmission chain 18, the agitating shaft 19, and the second transmission chain 29, avoiding the influence that the additive at the top of the storage bin 14 caking and unable to fall in the initial state). The rotation of the linkage shaft 20 drives the rotating turbine 22 to rotate through a number of bevel gear sets 21 (as Figure 2 shown, the bevel gear set 21 is a bevel gear transmission mechanism. The setting of the bevel gear set 21 can change the transmission ratio and increase the rotational speed of the bevel gear connected to the rotating turbine 22, thereby increasing the rotational speed of the rotating turbine 22). The rotation of the rotating turbine 22 stirs and disperses the additive inside the storage bin 14. At the same time, the rotation of the agitating shaft 19 drives the agitating wheel 16 to rotate to refine the falling additive. When the additive falls from the agitating wheel 16, it falls onto the surface of the rotating boss 26 through the blockage of the baffle inclined block 30. Since the rotating boss 26 rotates driven by the force receiving runner 9, at this time, due to the boss setting of the rotating boss 26, although the speed of the additive sliding on the rotating boss 26 is the same, the starting points of throwing are all different, making the additive more dispersed, so as to prevent the additive from caking and uneven mixing caused by concentrated addition in the later stage.

[0039] As a further solution of the present invention, the agitating wheel 16 penetrates through the circumference of the agitating shaft 19, and both ends of the agitating wheel 16 are rotatably connected to the fixed frame 15 provided on the inner wall of the reaction kettle body 1. The agitating wheel 16 is used to disperse the additive falling from the storage bin 14.

[0040] As a further solution of the present invention, a cam block 23 is provided at the bottom of the rotating turbine 22, and a reciprocating plate 24 slidably connected to the rotating turbine 22 is slidably connected to the surface of the cam block 23 (the rotating turbine 22 is slidably connected to the inner wall of the chute of the reciprocating plate 24 through a cross-shaped block), and the bottom of the reciprocating plate 24 is slidably connected to a fixing plate 25 provided on the outer wall of the reaction kettle body 1. A compression spring 28 connected to the fixing plate 25 is provided on the side of the reciprocating plate 24 away from the sliding connection with the cam block 23. The compression spring 28 is used to keep the reciprocating plate 24 in contact with the cam block 23.

[0041] As a further solution of the present invention, the top of the reciprocating plate 24 is slidably connected to the bottom of the storage bin 14, and the reciprocating plate 24 is used to vibrate the additive inside the storage bin 14.

[0042] As a further solution of the present invention, a set of material blocking inclined blocks 30 are arranged on the inner wall of the reaction kettle body 1 below the stirring wheel 16, and the material blocking inclined blocks 30 are used for guiding the falling additive.

[0043] As a further solution of the present invention, a rotating convex platform 26 is circumferentially arranged on the force-bearing rotating wheel 9, and a stirring fan blade 27 is arranged at the bottom of the force-bearing rotating wheel 9 below the rotating convex platform 26 and close to the bottom of the reaction kettle body 1. The rotating convex platform 26 is used for performing a projectile motion with different starting points on the falling additive, so as to increase the spraying range of the additive, and the stirring fan blade 27 is used for stirring the mixture;

[0044] At the same time, the rotation of the rotating turbine 22 drives the cam block 23 to rotate, and the rotation of the cam block 23 drives the reciprocating plate 24 to perform a reciprocating motion in the left-right direction (as Figure 2 shown, when viewed from the Figure 2 front view direction, the cam block 23 and the rotating turbine 22 are centrifugally fixedly connected. The cam block 23 is in a convex shape. The reciprocating plate 24 is clamped between the storage bin 14 and the fixed plate 25 to perform reciprocating motion. The left-right length of the reciprocating plate 24 is greater than the left-right length of the storage bin 14, and the length difference between the reciprocating plate 24 and the storage bin 14 is greater than the amplitude of the left-right motion of the reciprocating plate 24. The reciprocating motion of the reciprocating plate 24 ensures the stability of the additive during addition, preventing the phenomenon of excessive addition of the additive due to up and down vibration. The compression spring 28 ensures that the reciprocating plate 24 and the cam block 23 always keep in contact during motion, and only one compression spring 28 is arranged between the reciprocating plate 24 and the left fixed plate 25 to reduce the load of overcoming the elastic force for motion), and the reciprocating motion of the reciprocating plate 24 drives the additive above it to continuously perform reciprocating vibration, so that the internal additive is more fluffy and reduces the influence of the additive agglomeration in blocks.
