Description

Technical Field

[0002] Tape is one of the tools commonly used for fixing and shielding in daily life and work. According to its function, it can be divided into high-temperature tape, double-sided tape, shielding tape, special tape, pressure-sensitive tape and die-cut tape, etc.; Among them, shielding tape has the advantages of electromagnetic shielding, light shielding, component bonding and fixing, moisture and heat resistance, etc., which can effectively block electromagnetic waves, light sources, conductivity, etc. of electronic equipment; shielding tape generally includes a shielding layer, a substrate layer and an adhesive layer. When producing shielding tape, polyester film (PET) material is mostly used as the substrate layer. One side of the substrate layer is vacuum coated, and conductive materials such as aluminum foil, nickel-copper alloy, etc. are coated on the surface of the substrate layer to form a shielding layer; and glue is applied on the other side of the substrate to form an adhesive layer; and the shielding tape after glue coating needs to be dried and pressed to obtain the required shielding tape; the shielding tape produced at this time is a large roll of shielding tape; and according to the customer's demand for tape size, a tape slitting machine is also required to cut the large roll of shielding tape into small rolls of tape of the required size; finally, it can be packaged and transported; The existing shielding tape is cut by a knife shaft for cutting large rolls of shielding tape, but the blades on the knife shaft are fixed, so the distance between the blades is fixed, which means that each knife shaft can only cut one size of tape, and when the size of the small roll of tape to be cut needs to be changed, the knife shaft of the corresponding model must be replaced; and this process requires stopping the machine and replacing and adjusting the knife shaft, which increases the labor intensity of the staff and reduces production efficiency; in addition, the blade on the knife shaft is very sharp, and the staff needs to be very careful during the replacement of the knife shaft. If the operation is improper, it is easy to cause the staff to be cut and injured or the blade is damaged, resulting in fragments flying, which in turn causes injuries to the surrounding staff; In view of this, in order to overcome the above technical problems, the present invention proposes a shielding tape processing and slitting device and a process thereof, which solves the above technical problems.

[0020] As an embodiment of the present invention, the transmission unit includes a connecting rod 182; a square groove 181 is provided at the output end of the driving motor 151; the connecting rod 182 is slidably connected in the square groove 181; the connecting rod 182 is connected to the bottom of the square groove 181 through a supporting spring 183; an electromagnetic sheet 184 is inlaid at the bottom of the square groove 181; a clamping groove 212 matching the connecting rod 182 is provided at one end of the screw rod 211 close to the driving motor 151; a bevel gear ring 185 is fixedly connected to the surface of the connecting rod 182; a bevel gear shaft 163 is fixedly connected to the screw rod 161; the bevel gear ring 185 is meshed with the bevel gear shaft 163; During operation, the existing shielding tape is cut into large rolls of shielding tape by the knife shaft 13, but the knife disc 131 on the knife shaft 13 is fixed, so the distance between the knife discs 131 is fixed, which makes each knife shaft 13 only cut one size of tape, and when the size of the small roll of tape to be cut needs to be changed, the knife shaft 13 of the corresponding model must be replaced; and this process requires stopping the machine and replacing the knife shaft 13, which increases the labor intensity of the staff; in addition, the knife disc 131 on the knife shaft 13 is very sharp, and the staff needs to be very careful during the replacement of the knife shaft 13. If the operation is improper, it is easy to cause the staff to be cut and injured or the knife disc 131 is damaged, resulting in fragments flying, thereby causing injuries to the surrounding staff; In this regard, the present invention sets a push plate 2 so that the drive motor 151 drives the cutter shaft 13 and the bearing 14 away from each other through the screw 161, so that the cutter shaft 13 and the bearing 14 move to the adjacent push plate 2. At this time, the push plate 2 pushes the cutter discs 131 at both ends of the cutter shaft 13 and the U-shaped rings 141 at both ends of the bearing 14 to move away from each other through the slider 22, so that the distance between the cutter discs 131 increases, while the U-shaped rings 141 still remain opposite to the cutter discs 131, thereby adjusting the distance between the cutter discs 131 on the surface of the cutter shaft 13, without the need for the staff to replace the cutter shaft 13, reducing the labor intensity of the staff, avoiding the cutter shaft 13 from cutting and injuring the staff at this time, and preventing the cutter disc 131 from being damaged and causing fragments to splash, thereby avoiding injuries to the surrounding staff; improving the work safety of the staff; In the initial state, the blade shaft 13 and the bearing 14 are in a state of being away from each other, and the electromagnetic sheet 184 is in a power-off state. At this time, the connecting rod 182 extends out of the square groove 181 and is inserted into the card groove 212 under the push of the restoring force of the support spring 183. At this time, the screw rod 211 is connected to the drive motor 151 through the connecting rod 182, and the bevel gear ring 185 on the surface of the connecting rod 182 and the bevel gear shaft 163 on the surface of the screw rod 161 are in a separated state; the user puts a large roll of shielding tape on the support roller 11, and then puts the support roller 11 1 is pushed into the groove at one end of the machine body 1, so that the support roller 11 is rotatably connected to the machine body 1 through the groove, and then one end of the shielding tape roll is pulled to pass through multiple guide rollers 12 to between the knife shaft 13 and the bearing 14. The guide roller 12 is used to adjust the tension and guide the shielding tape. When the guide roller 12 guides the shielding tape, the shielding tape can be kept in a taut state, thereby ensuring that the shielding tape is in a flat state between the knife shaft 13 and the bearing 14; after the tape passes through the knife shaft 13 and the bearing 14, The tape adheres to the tape roller 15 located below, and then the electromagnetic sheet 184 is energized, so that the electromagnetic sheet 184 generates magnetic force and adsorbs the connecting rod 182 to squeeze the supporting spring 183 into the square groove 181, so that the connecting rod 182 drives the bevel gear ring 185 on the surface to approach the bevel gear shaft 163 until the bevel gear ring 185 is meshed with the bevel gear shaft 163. At this time, the connecting rod 182 is completely extended out of the card slot 212, the screw rod 211 is separated from the output shaft of the driving motor 151, and the screw rod 161 passes through the bevel gear shaft. The bevel gear ring 185 is connected to the output shaft of the driving motor 151 to control the driving motor 151 to rotate, so that the driving motor 151 can drive the screw 161 to rotate through the bevel gear ring 185 and the bevel gear shaft 163, so that the screw 161 can drive the two mounting blocks 162 connected with the screw drive to approach each other during the rotation process, so that the two mounting blocks 162 drive the cutter shaft 13 and the bearing 14 to approach each other, so that the cutter disc 131 on the surface of the cutter shaft 13 is close to the U-shaped ring 141 on the surface of the bearing 14;Until the blade shaft 13 contacts the shielding tape, because the tape is in a taut state when it contacts the U-shaped ring 141, the blade shaft 13 drives the blade disc 131 to squeeze the taut shielding tape, so that the blade disc 131 can cut into the taut shielding tape and enter the U-shaped groove of the U-shaped ring 141, and then the drive motor 151 is controlled to operate, so that the drive motor 151 can drive the tape roller 15 to rotate, so that the shielding tape is wound around the tape roller 15. At this time, the shielding tape between the blade shaft 13 and the bearing 14 is pulled and continuously moves toward the tape roller 15. At this time, the knife disc 131 and the U-shaped ring 141 cooperate to cut the shielding tape that is continuously stretched between the two, so that the cut tape moves to the tape roller 15, and the part to be cut on the tape roller 15 is cut off. At this time, the small-sized shielding tape cut by the knife disc 131 is wound between the upper and lower tape rollers in sequence, so that two adjacent small-sized shielding tapes are wound on the upper and lower tape rollers, so that the cut small-sized shielding tapes can be separated from each other in the process of winding up and down and torn apart, thereby accelerating the separation of the cut small-sized shielding tapes; When the distance between the cutter discs 131 needs to be adjusted, the servo motor 18 is first controlled to drive the cutter shaft 13 and the bearing 14 away from each other through the screw 161 until the cutter shaft 13 and the bearing 14 are close to the adjacent pushing plate 2, at which time the cutter disc 131 is located below the slider 22; in the initial state, the cutter disc 131 at the center of the cutter shaft 13 is fixedly connected to the cutter shaft 13, and the screws 211 on the two pushing plates 2 are connected by a belt drive through a transmission belt. The pushing rod 223 at the lower end of the slider 22 extends out of the groove 222 under the push of the connecting spring 224 and is located on both sides of the cutter disc 131 at the center of the cutter shaft 13, and the distance detector 221 on the side where the pushing rod 223 is close to each other is energized, so that the distance detector 221 is energized. The detector 221 can sense the distance between the two sliders 22 and the center cutter disc 131. At this time, the electromagnetic sheet 184 is controlled to be de-energized, so that the connecting rod 182 extends out of the square slot 181 under the push of the restoring force of the support spring 183, so that the connecting rod 182 drives the bevel gear ring 185 away from the bevel gear shaft 163 until the connecting rod 182 enters the slot 212. At this time, the servo motor 18 is controlled to operate, so that the servo motor 18 can drive the screw rod 211 to rotate through the connecting rod 182, so that the screw rod 211 drives the two sliders 22 in the same slide slot 21 to move away from each other, so that during the movement of the sliders 22, the two sliders 22 can be pushed by the push rod 223. The blade discs 131 on both sides are continuously moved away from the blade disc 131 in the center until the distance between the distance detector 221 sensor and the center blade disc 131 reaches the set distance, and the electromagnetic ring 225 is energized so that the electromagnetic ring 225 can absorb the push rod 223 and enter the groove 222. At this time, the control screw 211 drives the two sliders 22 to move away from each other, so that the two sliders 22 can pass over the blade disc 131 below to one side thereof, and then the control electromagnetic sheet 184 is de-energized so that the push rod 223 extends out of the groove 222 under the push of the restoring force of the connecting spring 224. At this time, the push rod 223 is located on one side of the blade disc 131, and the control screw 211 drives the push rod 223 through the slider 22. 23 is away from the cutter disc 131, so that the push rod 223 pushes the cutter disc 131 adjacent to the cutter disc 131 to move away from the center cutter disc 131, until the distance detector 221 detects that the distance from the cutter disc 131 is a set value; the electromagnetic sheet 184 is controlled to be energized again and the push rod 223 is adsorbed into the groove 222, and the slider 22 is driven by the screw rod 211 to pass over the pushed cutter disc 131, and this is repeated, thereby pushing the distance between the cutter discs 131 on the cutter shaft 13 to change (the distance between the cutter discs 131 increases). By setting the distance detector 221, the distance between the two adjacent cutter discs 131 can be accurately controlled by the push rod 223;Thus, the size of the cut shielding tape is ensured to be accurate. Similarly, since the screw rods 211 on the two push plates 2 are connected by a transmission belt, the screw rods 211 of the two push plates 2 rotate in the same direction and speed, so that the upper and lower sliders 22 can move synchronously, so that the pushed U-shaped ring 141 moves synchronously with the corresponding cutter disc 131, thereby ensuring that the cutter disc 131 and the U-shaped ring 141 can be accurately aligned. Then, the electromagnetic sheet 184 is controlled to be energized, so that the electromagnetic sheet 184 again absorbs the connecting rod 182 into the square groove 181, so that the servo motor 18 drives the screw rod 161 to rotate, thereby controlling the knife shaft 13 and the bearing 14 to approach each other, so that the knife disc 131 of the knife shaft 13 and the U-shaped ring 141 of the bearing 14 cooperate again, so as to ensure that the cutter disc 131 can stably split the shielding tape. ;

At this time, the push rod 223 will generate sliding friction with the cutter disc 131, so that the cutter disc 131 will shake under the action of the sliding friction, thereby affecting the accuracy of the position of the cutter disc 131. To this end, the present invention sets a rack 231. In the initial state, the electric push rod 232 extends and pushes the rack 231 close to the cutter disc 131, so that the rack 231 is meshed with the teeth 233, so that the cutter disc 131 is fixed to the rack 231 through the teeth 233, so that the cutter disc 131 is fixed in the strip groove 17; when the user drives the two sliders 22 to approach the cutter disc 131 to be pushed by the screw rod 211, the electric push rod 232 is controlled to retract and pull the rack 231 down, so that the rack 231 does not mesh with the teeth 233. The blade disc 131 is limited so that the blade disc 131 can slide in the strip groove 17; at this time, the slider 22 pushes the teeth 233 to slide in the strip groove 17, so that the push rod 223 in the blade disc 131 is pushed to the specified position, and at this time, the teeth 233 connected to the blade disc 131 are directly opposite to the teeth of the rack 231; when it is necessary to control the electromagnetic sheet 184 to be energized to adsorb the push rod 223 to enter the groove 222, the electric push rod 232 is first controlled to push the rack 231 to rise, so that the rack 231 is meshed with the teeth 233, so that the rack 231 limits the teeth 233, so that the blade disc 131 will not shake along the strip groove 17 under the action of the friction resistance of the push rod 223, thereby ensuring the accuracy of the position of the blade disc 131, so that the blade disc 131 can be accurately aligned with the U-shaped ring 141 and the shielding tape can be accurately divided, so that the practicality of the present invention is improved; When the slider 22 pushes the four knife discs 131 near the two ends of the knife shaft 13, two adjacent knife discs 131 will contact each other, so that the two knife discs 131 at the two ends will block the adjacent knife discs 131 from continuing to move, which will lead to insufficient size of the shielding tape near the two ends of the knife shaft 13, and thus waste of the shielding tape of the knife shaft 13. To this end, the present invention sets a storage shell 24. When the knife discs 131 at the two ends of the knife shaft 13 block the adjacent knife discs 131 from moving toward the two ends of the knife shaft 13, the electromagnetic sheet 184 is first controlled to be energized to adsorb the push rod 223 into the groove 222, and then the screw rod 211 is controlled to drive the slider 22 to between the two knife discs 131. The electric The magnetic sheet 184 is powered off, so that the connecting spring 224 pushes the push rod 223 out of the groove 222 and inserts it between the two knife discs 131, so that the two knife discs 131 are separated. At this time, the electromagnetic plate 25 is controlled to be energized, so that the electromagnetic plate 25 not only absorbs the push ring 242 into the storage groove 241, but also absorbs the blocking plate 262 to squeeze the return spring 263 close to the electromagnetic plate 25, so that the space between the blocking plate 262 and the blocking rod 261 is increased, so that the blocking rod 261 enters the blocking groove 26 under the adsorption of negative pressure. At this time, the control screw rod 211 drives the two sliders 22 to move away from each other, so that the two sliders 22 push the two knife discs 131 near the two ends of the knife shaft 13. The disc 131 is close to the storage shell 24, so that the blade disc 131 can pass through the blocking groove 26 to the storage groove 241, and the power of the control electromagnetic plate 25 is continuously weakened until it is powered off. Since the elastic force of the return spring 263 is less than the elastic force of the push spring 243, the push ring 242 first extends out of the storage groove 241 under the push of the restoring force of the push spring 243, but the slider 22 blocks the blade disc 131, that is, the slider 22 blocks the push ring 242 from moving through the blade disc 131; then the return spring 263 pushes the blocking plate 262 away from the electromagnetic plate 25, so that the blocking plate 262 pushes the blocking rod 261 out of the blocking groove 26 and to The cutter disc 131 is blocked, and at this time, the cutter disc 131 is located in the storage groove 241 under the blocking of the blocking rod 261; then the screw rod 211 is controlled to drive the slider 22 to approach each other and push the cutter disc 131 on the surface of the cutter shaft 13 and close to the storage groove 241 to move to a set distance, and at this time, the electric push rod 232 is controlled to push the rack 231 to engage with the teeth 233, so as to fix the cutter disc 131, thereby avoiding the two cutter discs 131 at the two ends blocking the adjacent cutter discs 131 from continuing to move, ensuring that the size of the shielding tape cut by the cutter disc 131 at both ends of the cutter shaft 13 meets the standard, thereby reducing the waste of shielding tape and improving the practicality of the present invention;When the distance between the blade discs 131 needs to be reduced, the user needs to first control the electromagnetic plate 25 to be energized, so that the magnetic force of the electromagnetic plate 25 just attracts the blocking plate 262 to squeeze the return spring 263 close to the electromagnetic plate 25, so that the blocking rod 261 enters the blocking groove 26 under the action of negative pressure. At this time, the pushing force of the pushing spring 243 on the pushing ring 242 is greater than the adsorption force of the electromagnetic plate 25, so that the pushing ring 242 extends out of the storage groove 241 under the push of the pushing spring 243, so that the pushing ring 242 pushes The movable cutter disc 131 is moved to the surface of the cutter shaft 13, so that the cutter disc 131 is above the rack 231. The slider 22 is first controlled to push the cutter disc 131 to the set position through the push rod 223, and then the slider 22 is controlled to push the push ring 242 into the storage groove 241. At this time, the electromagnetic plate 25 is controlled to be powered off. At this time, the blocking rod 261 extends out of the blocking groove 26 and blocks the push ring 242. Similarly, the U-shaped rings 141 at both ends of the bearing 14 are also pushed by the slider 22 to store dust in the storage groove 241. ;

[0024] A shielding tape processing and slitting process, the steps of the process are as follows: S1: The user uses a vacuum coating machine to coat a nickel-copper alloy layer on one side of a polyester film, and then uses a hot press machine to heat-press the polyester film coated with the nickel-copper alloy layer, and then coats glue on the side of the polyester film away from the nickel-copper alloy layer, and dries it to obtain a glue layer, and then presses it to obtain the required large roll of shielding tape; S2: Place a large roll of shielding tape on the support roller 11, pull one end of the tape through the guide roller 12 and between the knife shaft 13 and the bearing 14 to the tape roller 15, control the servo motor 18 to drive the knife shaft 13 and the bearing 14 to approach each other, so that the knife disc 131 will cut into the stretched shielding tape, control the drive motor 151 to drive the tape roller 15 to wind the shielding tape, so that the knife disc 131 cuts the shielding tape, and when the cut shielding tape reaches the tape roller 15, the user winds the cut small-sized shielding tape on the upper and lower tape rollers 15 respectively; S3: When the distance between the cutter discs 131 needs to be adjusted, the servo motor 18 is controlled to drive the cutter shaft 13 and the bearing 14 to move away from each other, so that the cutter disc 131 and the U-shaped ring 141 are between the push rods 223 that are close to them, so that the two adjacent push rods 223 push the cutter disc 131 and the U-shaped ring 141 to move synchronously, so that the distance between the two adjacent cutter discs 131 and the two adjacent U-shaped rings 141 increases or decreases; S4: After adjusting the distance between the cutter discs 131, control the servo motor 18 to drive the cutter shaft 13 and the bearing 14 to approach each other, so that the cutter disc 131 cuts the shielding tape, and the cut shielding tape is wound on the paper sleeve on the tape roller 15. When the shielding tape on the paper sleeve reaches the required winding size, the user removes the wound shielding tape and replaces it with a new paper sleeve to wind the shielding tape, and the removed shielding tape is packed.
