Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of metal foil cutting, and specifically relates to a metal foil cutting device and method for electromechanical engineering. BACKGROUND

[0002] Metal foil is a thin metal sheet made of metal extension, mainly including red gold foil stamping and pure silver foil and stamping, and the metal foil is a very thin metal sheet, which is generally manufactured by hammering or rolling. The metal foil is mostly made of materials with good ductility, such as aluminum, copper, tin and gold. The metal foil is generally bent due to its weight and can be easily torn. The better the ductility of the metal, the thinner the metal foil can be made. For example, the thickness of aluminum foil is generally 1 / 1000 inch, and gold with better ductility can be made into gold foil with a thickness of only a few atomic thicknesses. Metal foil is commonly used in daily life. If hypothermia is caused by heat radiation, metal foil can also be used to reduce heat radiation to improve symptoms. At present, the metal foil used in electromechanical engineering needs to be processed and cut from the foil sheet wound in a roll, and needs to be cut into a piece by piece sheet shape. However, the cutting means for the metal foil in the prior art is to use a small cutting machine. During the cutting process, the metal blade of the cutting machine will probably generate static electricity with the metal foil of aluminum sheet material. The generation of static electricity is not conducive to the cutting work. Static adsorption can cause scratches, folds on the surface of the metal foil or continuous adhesion to some metal structures, causing passive cutting of other metal foil sheets, affecting the production process.

[0013] A metal foil cutting method for electromechanical engineering is provided, and the specific cutting process is as follows: S1, start the conveying assembly to drive the metal foil to translate, after the metal foil is flattened by the two roller frame, the conveying assembly will be passively stopped, in this period, the telescopic cylinder on the U-shaped frame will drive the cutting knife to move down, the moving down process will pass through two sponges, and the wiping of the two sponges can prevent impurities from adhering to the surface of the cutting knife; S2, the cutting knife continuously moves down, which drives the bending pressing plate rod to abut against and press the piston rubber plate, so that the piston rubber plate is passively moved down in the piston cylinder I, at the same time, the moving down extrusion spring is deformed, and the existence of the spring facilitates the subsequent driving of the no longer stressed piston rubber plate to move up again. The piston rubber plate moves down in the piston cylinder I to passively generate negative pressure in the piston cylinder I, so that the anti-static agent placed in the piston cylinder I is extruded, and the stressed anti-static agent is finally sprayed from the plurality of atomizing nozzles through the T-shaped inclined groove plate, thereby being sprayed onto the surface of the moving down cutting knife. Since the surface of the cutting knife is sprayed with the anti-static agent, static electricity between the cutting knife and the metal foil can be avoided.

Therefore, the internal space of one side of the conveying assembly blocked by the blocking plate is pulled, so that a certain negative pressure suction degree is generated in the internal space. The suction degree is sufficient to pass through the plurality of air holes to adsorb the metal foil on the conveying assembly, thereby achieving a positioning effect.

When the two sponges are passively extruded, the extrusion force is transmitted to the elastic members at both ends, causing them to shrink, thereby ensuring the close fit between the sponge and the surface of the cutting knife. 2、The cutting knife continuously moves downward, driving the bending pressing plate rod to abut against the piston rubber plate, so that the piston cylinder one passively moves downward, and at the same time, the downward extrusion spring is deformed. The existence of the spring facilitates the subsequent upward movement of the no longer stressed piston rubber plate for resetting, thereby extruding the anti-static agent placed in the piston cylinder one. The stressed anti-static agent passes through the T-shaped inclined groove plate and is finally sprayed from the plurality of atomizing nozzles, thereby being sprayed onto the surface of the downward moving cutting knife.

The work-shaped gear rod in rotation drives the synchronous belt to rotate synchronously, thereby driving the screw rubber plate to rotate and translate in the piston cylinder two. A certain negative pressure suction force is generated in the piston cylinder two, which is sufficient to pass through the plurality of air holes to adsorb the metal foil on the conveying assembly, thereby achieving a positioning effect. The metal foil is prevented from deviating during cutting or not being closely attached to the conveying assembly and the arc plate, thereby avoiding cutting deviation and resulting in defective products.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0018] As Figures 1 to 8 shown, the present application provides a metal foil cutting device for electromechanical engineering, which comprises an electromechanical box table 1, a conveying assembly 11 fixedly connected to the electromechanical box table 1, a metal foil 12 attached to the top end of the conveying assembly 11, a plurality of air holes 13 through the middle part of the conveying assembly 11, a baffle 14 fixedly connected between the inner walls of the two end plate bodies of the conveying assembly 11, a cutting part 2 provided on the top end plate body of the conveying assembly 11, the cutting part 2 comprising a limiting plate 21 fixedly connected to the outer wall of the top end of the conveying assembly 11, the two end inner walls of the limiting plate 21 being respectively and slidably connected to the two ends of the metal foil 12, two roller brackets 22 fixedly connected to the top end outer walls of the two sides of the conveying assembly 11, the roller faces of the two roller brackets 22 being rollably connected to the top end of the metal foil 12, an arc plate 23 fixedly connected between the inner walls of the two end plate bodies of the conveying assembly 11, and a U-shaped frame 24 fixedly connected to the top end outer walls of the two sides of the conveying assembly 11, the top end inner wall of the U-shaped frame 24 being fixedly connected with a telescopic electric cylinder 25, and the bottom end of the telescopic electric cylinder 25 being fixedly connected with a cutting knife 26; The U-shaped frame 24 is provided with a cleaning structure capable of wiping the cutting knife 26, and the two ends of the cutting knife 26 and the outer walls of the two ends of the U-shaped frame 24 are jointly provided with piston structures for preventing static electricity between the cutting knife 26 and the metal foil 12, and for locally creating negative pressure inside the conveying assembly 11.

[0019] By the above scheme: by passing the metal foil 12 through the limiting plate 21, and then starting the conveying assembly 11 through the electromechanical box table 1 to drive the metal foil 12 to translate, the metal foil 12 is automatically and gradually passed through the two roller plate frames 22 during passive translation, and the two roller plate frames 22 can roll the arc surface that may exist in the early stage of the metal foil 12 in the form of a roll. Once the metal foil 12 is passed through the two roller plate frames 22 to be flattened, the conveying assembly 11 will be passively stopped to deliver, and during this period, the telescopic cylinder 25 on the U-shaped frame 24 will drive the cutting knife 26 to move downward.

[0020] The cleaning structure includes two U-shaped plates 27 fixedly connected to the inner walls of the two ends of the U-shaped frame 24, respectively, two telescopic elastic members 28 are fixedly connected to the inner walls of the two ends of the two U-shaped plates 27, respectively, one metal plate 29 is fixedly connected to the other end of the rod body of the two telescopic elastic members 28, respectively, and a sponge 230 is fixedly connected to the other end of the rod body of one metal plate 29. The other end of one sponge 230 can be intermittently and slidingly connected to the outer wall of the two ends of the cutting knife 26.

[0021] By the above scheme: the cutting knife 26 moves downward and passes through the two sponges 230, and the wiping of the two sponges 230 can prevent impurities from adhering to the surface of the cutting knife 26, which avoids the existence of impurities that may cause uneven cutting of the metal foil 12, and when the two sponges 230 are passively extruded, the extrusion force is transmitted to the telescopic elastic members 28 on both ends at the same time, so that the telescopic elastic members 28 are contracted, thereby ensuring the close contact between the sponge 230 and the surface of the cutting knife 26.

[0022] The two piston structures each comprise a bent pressing plate rod 231 fixedly connected to the side wall of the cutting knife 26, one end plate body of the bent pressing plate rod 231 is intermittently attached with a piston rubber plate 232, the piston rubber plate 232 is slidably connected to a piston cylinder I 233, the spring 234 is fixedly connected between the bottom end outer wall of the piston rubber plate 232 and the bottom end inner wall of the piston cylinder I 233, the T-shaped inclined groove plate 235 is fixedly connected to one end of the piston cylinder I 233, a plurality of atomizing nozzles 236 are fixedly connected to one end plate body of the T-shaped inclined groove plate 235, the sleeve rod 237 is fixedly connected to the outer wall of the piston cylinder I 233, the two end rod bodies of the sleeve rod 237 are fixedly connected to the two end plate bodies of the U-shaped frame 24, the material pipe 238 is fixedly connected to the bottom end side wall of the piston cylinder I 233, the filter screen 239 is fixedly connected to the bottom end inner wall of the material pipe 238, and the one-way valve 240 is fixedly connected to the pipe body of the material pipe 238.

[0023] The above scheme: the cutting knife 26 continuously moves downward, which drives the bent pressing plate rod 231 to abut and press the piston rubber plate 232, so that the piston rubber plate 232 is passively moved downward in the piston cylinder I 233, at the same time, the downward extrusion of the spring 234 causes the spring 234 to deform, and the presence of the spring 234 facilitates the subsequent upward movement of the piston rubber plate 232 which is no longer stressed to reset, thereby extruding the anti-static agent placed in the piston cylinder I 233, the stressed anti-static agent is finally sprayed from the plurality of atomizing nozzles 236 through the T-shaped inclined groove plate 235, thereby being sprayed onto the surface of the cutting knife 26 which moves downward, so that the surface of the cutting knife 26 is coated with the anti-static agent, thereby avoiding static electricity generated between the cutting knife 26 and the metal foil 12, when the piston rubber plate 232 is upwardly reset, the suction force generated will enter the piston cylinder I 233 through the material pipe 238 and the filter screen 239, the installation of the filter screen 239 can avoid some particulate impurities from entering, and the material pipe 238 is also used for subsequent material supplementing into the piston cylinder I 233, and the one-way valve 240 installed on the material pipe 238 is used to allow the anti-static agent to only enter but not exit.

[0024] The L-shaped tooth plate 241 is fixedly connected to one end of the outer wall of the cutting knife 26, the L-shaped tooth plate 241 is intermittently meshed with the I-shaped gear rod 242, the I-shaped gear rod 242 is movably sleeved with one end plate body of the U-shaped frame 24, the synchronous belt 243 is fixedly connected to the other end of the I-shaped gear rod 242, the screw rubber plate 244 is threadedly connected to the other side of the synchronous belt 243, the piston cylinder II 245 is rotatably connected to the screw rubber plate 244, one section of the piston cylinder II 245 is fixedly connected to one end plate body of the conveying assembly 11, and a plurality of air grooves 246 are annularly and throughly formed in the other end of the piston cylinder II 245.

[0025] With the above scheme: in the process of moving down the cutting knife 26, the installed L-shaped tooth plate 241 will also move down at the same time, the movement of the L-shaped tooth plate 241 drives the work-shaped gear rod 242 engaged with it to rotate and position on the U-shaped frame 24. Thus, the rotating work-shaped gear rod 242 will drive the synchronous belt 243 to rotate synchronously, and in turn drive the screw rubber plate 244 installed on one side to rotate and translate in the piston cylinder two 245. Thus, the inside space of the transmission assembly 11 blocked by the baffle 14 is pulled, so that a certain negative pressure suction force is generated inside, which is sufficient to pass through the plurality of air holes 13 to adsorb the metal foil 12 on the surface of the transmission assembly 11 when it is paused, so as to achieve a positioning effect, avoid the metal foil 12 from shifting during cutting, or not enough to fit the transmission assembly 11 and the curved surface plate 23 to cause cutting deviation, resulting in defective products.

[0026] A metal foil cutting method for mechanical and electrical engineering, the specific cutting process is as follows: S1, start the transmission assembly 11 to drive the metal foil 12 to translate, after the metal foil 12 passes through the two roller plate frames 22 to flatten, the transmission assembly 11 will be passively stopped for conveying, during which the telescopic cylinder 25 on the U-shaped frame 24 will drive the cutting knife 26 to move down, and the moving down process will pass through the two sponges 230. The wiping of the two sponges 230 can prevent impurities from adhering to the surface of the cutting knife 26; S2, in the process of continuously moving down the cutting knife 26, the bending pressing plate rod 231 will be pressed against the piston rubber plate 232 to move down passively in the piston cylinder one 233, at the same time, the moving down extrusion spring 234 will deform, and the presence of the spring 234 will facilitate the subsequent movement of the piston rubber plate 232 without force to move up again. Thus, the movement of the piston rubber plate 232 in the piston cylinder one 233 generates negative pressure inside, which can extrude the anti-static agent placed in the piston cylinder one 233. The stressed anti-static agent will pass through the T-shaped inclined chute plate 235 and finally be sprayed from the plurality of atomizing nozzles 236, thereby being sprayed onto the surface of the moving down cutting knife 26. Since the cutting knife 26 is coated with an anti-static agent, this can avoid static electricity from being generated between the metal foil 12 and the cutting knife 26; S3, and in the process of moving down the cutting knife 26, the installed L-shaped tooth plate 241 will also move down at the same time, drive the work-shaped gear rod 242 engaged with it to rotate and position on the U-shaped frame 24, so that the rotating work-shaped gear rod 242 will drive the synchronous belt 243 to rotate and drive the screw rubber plate 244 to rotate and translate in the piston cylinder two 245, thereby pulling the internal space of the conveying assembly 11 blocked by the blocking plate 14 to generate a certain negative pressure suction degree, which is sufficient to pass through a plurality of air holes 13 to adsorb the metal foil 12 on the conveying assembly, which has a positioning effect, avoiding the offset of the metal foil 12 during cutting or the insufficient adhesion of the conveying assembly 11 and the cambered plate 23, resulting in cutting deviation and causing defective products.

[0027] The working principle and use process of the present application: by passing the metal foil 12 through the limiting plate 21, and then through the electromechanical box table 1 to start the transmission assembly 11 to drive the metal foil 12 to translate, the metal foil 12 is passively translated, and will automatically gradually pass through the two roller plate racks 22, which can roll the arc surface that may exist in the early stage of the coil form, once the metal foil 12 passes through the two roller plate racks 22 to be flattened, then the transmission assembly 11 will be passively stopped to deliver, during which the telescopic cylinder 25 on the U-shaped frame 24 will drive the cutting knife 26 to move down, the cutting knife 26 will pass through the two sponges 230 during the downward movement, and the wiping of the two sponges 230 can prevent impurities from adhering to the surface of the cutting knife 26, which can prevent the existence of impurities from causing uneven cutting of the metal foil 12, and when the two sponges 230 are passively extruded, the extrusion force will be transmitted to the two ends of the elastic member 28, causing it to shrink, thereby ensuring the close fit between the sponge 230 and the surface of the cutting knife 26. During the continuous downward movement of the cutting knife 26, the bending pressing plate rod 231 will also be pressed against the piston rubber plate 232, causing it to passively move down in the piston cylinder 1 233, at the same time, the downward extrusion spring 234 will be deformed, and the presence of the spring 234 will facilitate the subsequent upward movement of the piston rubber plate 232 to reset, thereby causing the piston rubber plate 232 to move down in the piston cylinder 1 233 to passively generate negative pressure inside, which can extrude the anti-static agent placed in the piston cylinder 1 233, and the stressed anti-static agent will pass through the T-shaped inclined groove plate 235 and finally be sprayed from the plurality of atomizing nozzles 236, thereby being sprayed onto the surface of the cutting knife 26 moving down, so that the cutting knife 26 can cut the metal foil 12 moving onto the arc surface plate 23 into pieces when it moves down to the arc surface plate 23, and the cutting knife 26 and the metal foil 12 are in contact during cutting, and because the surface of the cutting knife 26 is sprayed with anti-static agent, this can avoid static electricity between the cutting knife 26 and the metal foil 12, and avoid the possible events of sparks, surface scratches, and attached metal structures on the metal foil 12 due to static electricity. When the piston rubber plate 232 is reset upward, the suction force generated will pass through the material pipe 238 and the filter screen 239 into the piston cylinder 1 233, and the installation of the filter screen 239 can prevent some particulate impurities from entering, and the material pipe 238 is also used for subsequent material replenishment to the piston cylinder 1 233, and the one-way valve 240 installed on the material pipe 238 is used to allow the anti-static agent to only enter but not exit; And in the process of moving down the cutting knife 26, it will also drive the installed L-shaped tooth plate 241 to move down at the same time, the L-shaped tooth plate 241 drives the work gear bar 242 engaged with it to rotate positioning on the U-shaped frame 24, whereby the rotating work gear bar 242 will drive the synchronous belt 243 to rotate synchronously, and in turn drive the screw rubber plate 244 installed on one side to rotate and translate in the piston cylinder two 245, thereby pumping the internal space of the conveying assembly 11 blocked by the blocking plate 14 to generate a certain negative pressure suction degree, which is sufficient to pass through the plurality of air holes 13 to adsorb the metal foil 12 on the surface of the conveying assembly 11 when it is paused, so as to achieve a positioning effect, avoid the metal foil 12 from producing deviation during cutting or not enough to fit with the conveying assembly 11 and the cambered plate 23 to produce cutting deviation, resulting in defective products, so as to ensure the production quality and avoid the static electricity event during cutting.

The rod body of the I-shaped gear rod (242) and one end plate of the U-shaped frame (24) are movably connected.

9. The electromechanical engineering metal foil cutting device according to claim 8, characterized in that: One section of the piston cylinder (245) is fixedly connected to one end plate of the conveying assembly (11), and multiple air grooves (246) are provided around the other end of the piston cylinder (245).

10. A method for cutting metal foil for electromechanical engineering, characterized in that: The specific cutting process is as follows: S1. Start the conveying assembly (11) to move the metal foil (12) horizontally. After the metal foil (12) passes through the two roller plate frame (22) and is flattened, the conveying assembly (11) will passively stop conveying. During this period, the telescopic electric cylinder (25) on the U-shaped frame (24) will drive the cutting blade (26) to move downward. During the downward movement, it will pass through two sponges (230). The wiping by the two sponges (230) can prevent impurities from adhering to the surface of the cutting blade (26). S2. As the cutting blade (26) moves downward, it will cause the bending pressure plate rod (231) to press against the piston rubber plate (232), causing it to move downward passively within the piston cylinder (233). At the same time, the downward movement compresses the spring (234), causing it to deform. The presence of the spring (234) facilitates the subsequent upward movement and reset of the piston rubber plate (232), which is no longer under force. As a result, the piston rubber plate (232) moves downward within the piston cylinder (233), causing a negative pressure to be passively generated inside. This pressure can compress the antistatic agent placed inside the piston cylinder (233). The antistatic agent under force will pass through the T-shaped inclined plate (235) and finally be sprayed out from multiple atomizing nozzles (236), thus spraying onto the surface of the downward-moving cutting blade (26). Since the surface of the cutting blade (26) is coated with antistatic agent, static electricity can be avoided with the metal foil (12). S3. During the downward movement of the cutting blade (26), the L-shaped toothed plate (241) installed will also be moved downward at the same time, causing the I-shaped gear rod (242) meshing with it to be positioned and rotated on the U-shaped frame (24). The rotating I-shaped gear rod (242) will drive the synchronous belt (243) to rotate, thereby driving the screw rubber plate (244) to rotate and translate within the piston cylinder (245). This will draw out the internal space of the conveying assembly (11) after it is blocked by the baffle plate (14), so that a certain negative pressure suction force is generated inside. This force is sufficient to adsorb the metal foil (12) on the conveying assembly through multiple air holes (13), achieving a positioning effect and preventing the metal foil (12) from shifting during the cutting process or from not fitting well with the conveying assembly (11) and the arc panel (23), resulting in cutting deviation and producing defective products.
