Description

Technical Field

[0001] The invention belongs to the technical field of winding machines, and in particular relates to a terminal winding machine for producing heating films. Background Art

[0002] A winding machine is a device that winds linear objects onto a specific workpiece. It is usually used for winding copper wire or nickel-chromium heating wire. The fully automatic winding machine is a new type of machine that has only been developed in recent years. The production of heating film requires the use of a winding machine to wind the heating resistance wire into a certain curve and press it between insulating polyester films.

Rubber blocks 1509 are provided on the sides where the two clamping plates 1508 are close to each other. When in use, one end of the heating resistance wire 14 is placed between the two rubber blocks 1509, and then the hand wheel 1511 is rotated to make the bidirectional screw rod 1510 rotate, thereby driving the two threaded sleeves 1507 to move relative to each other, so that the two clamping plates 1508 are close to each other, and finally one end of the heating resistance wire 14 is clamped and fixed.

[0036] When in use, the servo motor 1101 drives the active rod 1102 to rotate, so that the active gear 1103 on the active rod 1102 rotates, and drives the rack 1001 on one side of the conveyor belt 10 to rotate, so that the conveyor belt 10 rotates around the active gear 1103, and then the rack 1001 on one side of the conveyor belt 10 drives to rotate around five driven gears 1202, so that the conveyor belt 10 rotates around the five driven gears 1202 and a driving gear 1103 in turn, and drives the clamping mechanism 15 on the lower side of the conveyor belt 10 to be transported together.

[0037] Example 2

[0038] like Figure 1 , Figure 2As shown, a polyester film 9 is laid on the upper surface of the base 1, and the upper surface of the polyester film 9 is coated with glue. A clamping mechanism 8 for clamping the edge of the polyester film 9 is arranged on both sides of the side plate 2. The clamping mechanism 8 includes a fixed plate 801 fixedly arranged between the two side plates 2, and the middle thread of the fixed plate 801 is connected with a one-way screw rod 802. The lower end of the one-way screw rod 802 is rotatably provided with a pressing plate 803 for clamping the edge of the polyester film 9. The upper end of the one-way screw rod 802 is fixedly provided with a handle.

When in use, the buffer spring 703 will be compressed in the process of driving the lifting plate 6 to descend by the pneumatic cylinder 4, and the buffer spring 703 can make the descent of the lifting plate 6 more stable, thereby preventing the heating resistor wire 14 from crushing the polyester film 9 due to excessive pressure.

[0041] It should be noted that, when using the terminal winding machine for the production of heating film, the polyester film 9 is first laid on the upper surface of the base 1, and then the one-way screw 802 is rotated so that the one-way screw 802 rotates on the middle thread of the fixed plate 801, and the one-way screw 802 is lowered, driving the pressure plate 803 at the lower end of the one-way screw 802 to descend, so that the two end edges of the polyester film 9 are pressed tightly, and then glue is applied on the upper surface of the polyester film 9, and then one end of the heating resistor wire 14 on the unwinding disk 1303 is clamped between the two rubber blocks 1509. Then, the hand wheel 1511 is rotated to rotate the bidirectional screw rod 1510, driving the two threaded sleeves 1507 to move relative to each other, so that the two clamping plates 1508 are close to each other, so that one end of the heating resistance wire 14 is clamped and fixed, and then the servo motor 1101 drives the active rod 1102 to rotate, so that the active gear 1103 on the active rod 1102 rotates, driving the rack 1001 on one side of the conveyor belt 10 to rotate, so that the conveyor belt 10 rotates around the active gear 1103, and then the rack 1001 on one side of the conveyor belt 10 drives the conveyor belt 10 to rotate around the five The driven gears 1202 rotate, so that the conveyor belt 10 rotates around the five driven gears 1202 and a driving gear 1103 in turn, driving the clamping mechanism 15 on the lower side of the conveyor belt 10 to be transported together. The clamping mechanism 15 clamps the heating resistance wire 14 and pulls the heating resistance wire 14 to be wound around the second annular groove 1203 at the lower end of the five driven rods 1201 and the outer side of the first annular groove 1104 at the lower end of the active rod 1102 for transportation and guidance, so that the heating resistance wire 14 forms a curve, and then the lifting plate 6 is driven down by the pneumatic cylinder 4. The lower surface of the heating resistor wire 14 on the lower side of the lifting plate 6 is made to contact with the glue on the upper surface of the polyester film 9, and then the hand wheel 1511 is rotated in the opposite direction to open the two clamping plates 1508. At the same time, the heating resistor wire 14 at one end of the unwinding disk 1303 is cut off, so that the heating resistor wire 14 can be adhered to the upper surface of the polyester film 9 according to a certain curve. Then, the lifting plate 6 is driven to rise by the pneumatic cylinder 4, and then another polyester film 9 is laid on the upper surface of the heating resistor wire 14, so that the heating resistor wire 14 is laid between the two layers of polyester film 9.

[0042] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention.
