Description

Technical field:

[0001] The invention relates to a fully automatic four-side cutting machine unit for a starting pole piece body, belonging to the technical field of metallurgical equipment. Background technology:

[0002] The electrolytic process is currently one of the main ways to obtain high-purity nonferrous metal materials. The electrolytic process is widely used in the production process of copper, nickel, and cobalt metal materials. In the electrolytic process, making the starting electrode is a major work content in the electrolytic process; the structure of the starting electrode consists of three parts, the first is the sheet body; the second is the ear; the third is the conductive rod. Among them, the sheet body of the starting electrode is made by electrolytic enrichment on a titanium plate, then peeled off, and after four-side trimming, leveling, embossing, ear hanging, rod threading and other processes, a cathode sheet is formed.

[0003] The sheet trimming work of the starting electrode sheet is carried out on the starting electrode sheet trimming unit. The stripped sheet is transported to the edge of the starting electrode sheet trimming unit equipment as recorded in the publication number CN206065913U by a box body, and the sheet is loaded onto the conveying device of the starting electrode sheet trimming unit by a loading unit. It is transported into two sets of mutually perpendicular rolling shearing devices in turn through two sets of conveying devices, and the two pairs of edges of the sheet are trimmed respectively to obtain sheets of uniform size; then it is collected through a box body and sent to the subsequent cathode manufacturing unit. After the trimmed sheet is loaded again, the copper starting electrode sheet, the ear, and the conductive rod are assembled on the cathode manufacturing unit to make a cathode for electrolysis.

[0004] First, the current pole piece trimming unit does not have a material box conveying mechanism, and the material box needs to be manually transferred to the lower part of the loading unit. The loading adopts a cylinder to suck the pole piece stack in the material box one by one. Since the material box is deep, during the suction process, as the pole piece body decreases, the cylinder needs to extend a lot when sucking the lower sheet body, which affects the feeding efficiency.

[0005] Secondly, the feeding unit includes a support frame that can move along the frame. A support plate is fixed at the bottom of the support frame through a cylinder. The support plate is arranged horizontally and can move up and down under the action of the cylinder. There are vertical suction cups at the four corners of the bottom of the support plate, which use negative pressure to absorb the sheet. When sucking materials, the suction cups are used to suck the stack of the starting sheets in the material box. The feeding unit sucks materials at the four corners of the starting sheets. The problems are as follows:

[0006] 1. Since the material is sucked at the four corners of the sheet, the sheet is extremely thin and soft, resulting in unstable material suction and easy collapse in the middle, causing the sheet to fall during the feeding process;

[0007] 2. The support plate is lifted and lowered by the cylinder, which is fixed on the fixed plate, and is prone to shaking, causing the sheet to fall during the loading process.

[0008] 3. A positioning rod is arranged at the lower part of the support plate, and the positioning rod is fixedly connected to the support plate. A proximity switch is arranged at the lower part of the positioning rod. When the support plate is descending, after the proximity switch is close to or in contact with the sheet, the negative pressure of the suction cup is controlled to start, and the suction cup sucks the sheet. However, due to the fast descending speed of the support plate, the proximity switch is easy to directly press against the sheet. The sheet is extremely thin and soft, and it is easy to push out a pit on the sheet or even damage the sheet, or damage the proximity switch, thus affecting subsequent operations.

[0009] Furthermore, after the loading unit sends the sheet to the conveying unit of the trimming unit, the conventional conveying unit is a double-roller conveying mechanism. Since the sheet is relatively thin and the incoming material has a protrusion, there is a problem of inaccurate feeding when entering the double-roller scissors, and there is a problem of the sheet passing through the upper part of the double-roller scissors (commonly known as "material running"), resulting in the sheet not being cut; in addition, after the two pairs of edges of the starting sheet are cut, it is transferred to another conveying roller perpendicular to the aforementioned conveying roller, and then conveyed to another pair of double-roller scissors to cut the other two edges. In the process of transferring the sheet on the two mutually perpendicular conveying rollers, the sheet will tilt. Therefore, when cutting the other two edges, there is a problem of inaccurate alignment, that is, the cut sheet is not square, affecting subsequent use. Summary of the invention:

[0033] Advantages of the present invention:

[0034] The four-side cutting machine unit for the pole starter sheet of the present invention can realize full-automatic cutting of the pole starter sheet by arranging a material box conveying unit, a feeding unit, a cutting unit and a matching material box, and can ensure the cutting quality. Specifically:

[0035] 1. The top and one side of the conveying material box used in the material box conveying unit of the present invention are open, so that a forklift can transport the sheet into the box from the open side of the box; a through cavity is opened at the bottom of the box, so that a lifting device can lift the sheet from the bottom through cavity of the box; and lifting ears and / or square tubes are arranged on the box, so that the box can be transferred by overhead crane lifting or forklift loading.

[0036] 2. The material box conveying unit of the present invention is provided with a roller conveyor belt, a lifting device and a limiting device, which are used in conjunction with the box body. After the box body is conveyed to the loading station, the limiting device limits the box body, and the loading unit loads the sheet body. As the number of starting sheets decreases, the lifting device lifts the sheet body to prevent the lower sheet body from being too low, which causes a large elongation of the cylinder of the loading unit, affecting the loading efficiency.

[0037] 3. The loading unit of the present invention fixes a guide rod on the support plate, and the guide rod is slidably connected to the support frame, thereby avoiding the shaking of the support plate during the lifting process and ensuring smooth loading. In addition, suction straws are arranged on the edges and the middle of the support plate to further ensure the smooth lifting and transfer of the sheet during the loading process, avoiding the problem of sheet falling due to shaking in the traditional loading process.

[0038] 4. The feeding unit of the present invention slides the limit rod on which the lifting limit switch is installed with the support plate, thereby ensuring that the lifting limit switch will not damage the sheet body on the one hand and also ensuring the service life of the lifting limit switch on the other hand.

[0039] 5. The feeding unit of the present invention is connected by sliding the straw to the support plate, and a compression spring is provided to ensure the distance between the bottom end of the straw and the support plate. During the downward movement of the support plate, after the suction cup and the straw are in contact with the starting sheet, they may continue to move downward under the action of the impact force, and the straw can slide up for buffering, avoiding leaving marks on the sheet or even damaging the sheet, thereby ensuring the feeding effect.

[0040] 6. In the cutting unit of the present invention, before the pole piece enters the roller gap of the driving roller group on the first cutting conveyor belt and the second cutting conveyor belt, the roller gap of the pair of roller scissors group, and the roller gap of the flattening pair of rollers, there are horizontal guide plates to limit the position. Before the pole piece with warped edges enters the roller gap of the roller group, the warped edges of the pieces first contact the horizontal guide plate. During the forward conveying process, the warped edges slide along the plate surface of the horizontal guide plate until they are fed into the roller gap of the corresponding roller group, thereby avoiding material leakage.

[0041] 7. In the cutting unit of the present invention, before the starting sheet is driven by the transition scraper to be fed into the roller gap of the driving roller group of the second cutting conveyor belt, it is limited to the left and right by the vertical guide plates on both sides, ensuring that the sheet will not tilt. When cutting the other two sides, there is no problem of misalignment, that is, the sheet after cutting is square, ensuring the cutting quality.

[0042] 8. The present invention is provided with a controller, which can automatically control the actions of the lifting device, the limit device, the drive motor, the drive device, the lifting cylinder, the air pump, the alignment telescopic device, the feeding telescopic device, and the transition telescopic device according to the signals of the height sensor, the material box proximity switch, the lifting proximity switch, the loading position proximity switch, and the unloading position proximity switch, so as to realize the automatic conveying, loading, cutting, and collection of the starting sheet without manual participation, and has a high degree of automation.

[0071] Working process:

[0072] The stripped sheet 5 is delivered into the box 1.1 from the open side of the box 1.1 by a forklift, and then inserted into the square tube 1.1.4 by the forklift to lift the box 1.1, or the lifting lug 1.1.3 is lifted by an overhead crane to deliver the box 1.1 to the material box roller conveyor 1.2, and the material box roller conveyor 1.2 delivers the box 1.1 forward until the material box proximity switch 1.2.8 is triggered, and the controller 4 controls the limit cylinder 1.2.4.1 to extend, and the limit baffle 1.2.4.2 is pushed out to exceed the height of the upper surface of the roller, and the box 1.1 is delivered until it is supported by the limit baffle 1.2.4.2, and the controller 4 controls the drive motor 1.2.5 to stop, and at this time the box 1.1 is in the loading position for loading;

[0073] During loading, the controller 4 controls the piston rod of the driving cylinder 2.4 to extend, and the driving cylinder 2.4 drives the support frame 2.3 to move upward on the guide rail 2.2 until it contacts the loading position proximity switch 2.15. The loading position proximity switch 2.15 feeds back to the controller 4 to control the driving cylinder 2.4 to stop extending; the lifting cylinder 2.6 is started, and the piston rod of the lifting cylinder 2.6 extends, driving the support plate 2.5 to move downward until the lifting proximity switch 2.14 approaches or contacts the sheet body 5, and then controls the air pump 2. 11 is started, the suction cup 2.10 sucks the sheet 5, and at the same time controls the piston rod of the lifting cylinder 2.6 to retract and reset, and controls the piston rod of the driving cylinder 2.4 to retract, and the driving cylinder 2.4 drives the support frame 2.3 to move to the unloading position on the guide rail 2.2 until it contacts the unloading position proximity switch 2.16, and the unloading position proximity switch 2.16 feeds back to the controller 4, controls the driving cylinder 2.4 to stop retracting, and controls the air pump 2.11 to cut off the air, and the sheet 5 falls from the suction cup 2.10 and falls on the suction plate;

[0074] During the loading process, the sheets 5 in the box 1.1 are sucked and lifted one by one for loading. The height sensor 1.2.7 detects the height of the sheet 5 in the box 1.1. When the lower limit is reached, the controller 4 controls the lifting motor 1.2.3.1 to rotate, controls the screw of the screw elevator 1.2.3.3 to rise, and realizes the lifting of the sheet 53. When the sheet 5 is lifted to the upper limit, the controller 4 controls the lifting motor 1.2.3.1 to cut off the power and stop rotating, and the loading unit 2 continues to suck and load until all the sheets 5 are loaded; the controller 4 controls the lifting motor to reverse until the screw of the screw elevator is reset, the controller 4 controls the limit cylinder to retract and reset, and controls the drive motor 1.2.5 to start, so as to transport the empty box 1.1 backward, and continue to transport the box 1.1 to be loaded forward to perform the loading operation;

[0075] After the sheet 5 falls from the suction cup 2.10 to the loading tray, the controller 4 controls the piston rod of the alignment cylinder 3.4 to extend and retract twice continuously, and the push plate 3.6 pushes the sheet 5 to one side edge and abuts against the alignment limit plate 3.5. Then the controller 4 controls the piston rod of the feeding cylinder 3.3 to extend, driving the feeding scraper 3.2 to slide in the direction close to the first cutting conveyor belt 3.7. The feeding scraper 3.2 drives the starting sheet 5 to be cut forward and feeds it into the roller gap of the transmission roller group 3.7.2 of the first cutting conveyor belt 3.7. The transmission roller group 3.7.2 drives the starting sheet 5 to be cut to continue to move forward, passing through the roller scissors group 3.7.3 and the four flattening roller groups 3.7.4 on the first cutting conveyor belt 3.7. After trimming and flattening, the pole piece body 5 with trimmed edges on both sides is sent to the conveying roller 3.8.2 of the transition roller group conveyor belt and is limited by the baffle 3.8.4; the transition cylinder 3.8.5 is started to drive the transition scraper 3.8.3 to slide in the direction close to the second cutting conveyor belt 3.9, and the transition scraper 3.8.3 drives the pole piece body 5 to move forward and feed it into the roller gap between the transmission roller group 3.7.2 of the second cutting conveyor belt 3.9. The transmission roller group 3.7.2 drives the pole piece body 5 to continue to move forward. After trimming and flattening by the roller scissors group 3.7.3 and the four groups of flattening roller groups 3.7.4 on the second cutting conveyor belt 3.9, the pole piece body 5 with trimmed edges on the other two sides is sent to the rear material box for collection.

[0076] Before the pole piece enters the roller gap of the driving roller group 3.7.2, the roller gap of the roller scissors group 3.7.3 and the roller gap of the flattening roller group 3.7.4 on the first cutting conveyor belt 3.7 and the second cutting conveyor belt 3.9, there is a horizontal guide plate 3.10 to limit the position. When the pole piece body 5 with a warped edge enters the roller gap of the roller group, the warped edge of the sheet body 5 first contacts the horizontal guide plate 3.10. During the forward conveying process, the warped edge slides along the plate surface of the horizontal guide plate 3.10 until it is sent into the roller gap of the corresponding roller group, thereby avoiding material leakage.

[0077] Before the starting sheet 5 is driven by the transition scraper 3.8.3 to be fed into the roller gap of the driving roller group 3.7.2 of the second cutting conveyor belt 3.9, it is limited to the left and right by the vertical guide plates 3.11 on both sides, ensuring that the sheet 5 will not tilt. When cutting the other two sides, there is no problem of misalignment, that is, the sheet 5 after cutting is square, ensuring the cutting quality.

[0078] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
