[0002] A transformer is an electrical device used to transform AC voltage. It converts the input voltage into different levels of output voltage through the principle of electromagnetic induction. The core components of a transformer are the iron core and the winding. The iron core is usually laminated by silicon steel sheets to improve the magnetic flux density, while the winding is divided into a primary winding and a secondary winding, which are used to receive and output current respectively. Transformers are widely used in the power system for step-up or step-down to meet the needs of different electrical equipment. Small transformers are commonly used in household appliances, while large transformers are used in power stations and power grids. They are key equipment for power transmission and distribution. The use of transformers not only improves the efficiency of the power system but also enhances the reliability of power supply.

[0003] At present, the connecting leads inside the transformer need to be wrapped with insulating layers of different thicknesses according to different voltage levels. Currently, transformer manufacturers all use manual wrapping, which has low wrapping efficiency and poor tightness of the crepe paper. Summary of the Utility Model

[0005] To solve the above problems, the technical solution proposed by the utility model is: a transformer lead wrapping device, including a base, on which a number of mutually parallel chutes one are provided.

A driving gear one corresponding to the face gear is provided at the lower end of the control rod, and a number of bosses cooperating with the groove are provided on the side of the claw close to the coupling;

[0008] As an improvement, the bandaging mechanism includes support rods II respectively and slidably arranged in chute I. The upper ends of the two support rods II are respectively connected to both sides of the lower part of the outer shell II. One side of the outer shell II is provided with a motor I whose output shaft passes through the outer shell II. A driving gear II is arranged on the part of the output shaft of the motor I located inside the outer shell II. The middle part of the outer shell II is installed with a rotating block with a hollow structure in the middle through a bearing. A driven gear is arranged in the middle of the outer edge of the rotating block. A number of mounting rods for mounting crepe paper rolls are arranged on one side of the rotating block at equal angles. A baffle plate is arranged at the end of the mounting rod through a thread.

[0009] As an improvement, the driving mechanism includes a bidirectional lead screw rotatably arranged in the middle chute I and threadedly passing through two support rods I, and a unidirectional lead screw rotatably arranged in the chute I on both sides and passing through the support rod II. A number of motor II are arranged on one side of the base and are respectively key-connected to the bidirectional lead screw and the unidirectional lead screw.

[0010] The beneficial effects of the present utility model are as follows:

Driving mechanisms 4 for driving the movement of the fixing mechanisms 2 and the wrapping mechanisms 3 are respectively provided in a number of first chutes 101; by arranging two fixing mechanisms 4 driven by the driving mechanism 4 in the middle first chute 101 of the base 1, the two fixing mechanisms 4 can fix both ends of leads of different lengths. By arranging the wrapping mechanisms 3 driven by the driving mechanism 4 in the first chutes 101 on both sides of the base 1, the wrapping mechanism 4 can gradually wind crepe paper from one end of the lead to the other end, and the cooperation of the wrapping mechanism 3 and the driving mechanism 4 enables high wrapping efficiency and good take-up progress.

[0018] According to Figure 1 、 2 shows: The fixing mechanism 2 includes first rods 201 respectively slidably arranged on both sides of the first chute 101, outer casings 202 arranged at the upper ends of the first rods 201, couplings 203 rotatably arranged inside the outer casings 202, control rods 204 passing through the outer casings 202 and arranged on the side of the couplings 203 away from the opposite fixing mechanism 2, and a number of claws 205 slidably arranged at the ends of the outer casings 202 and arranged on the other side of the couplings 203; a number of second chutes 206 facing the axis of the outer casing 202 are equiangularly provided at one end of the outer casing 202 close to the symmetric outer casing 202. A face gear 207 is provided on one side of the coupling 203, and a groove 208 with a planar thread structure is provided on the other side. A first driving gear 209 corresponding to the face gear 207 is provided at the lower end of the control rod 204. A number of bosses 210 cooperating with the groove 208 are provided on the side of the claw 205 close to the coupling 203; thus, after placing the end of the lead in the middle of a number of claws 205 and rotating the control rod 204, under the cooperation of the first driving gear 209 and the face gear 207, the coupling 203 will rotate. Under the action of the groove 208 and the bosses 210, the number of claws 205 will approach or move away from each other, so as to fix or release the lead.

[0019] According to Figure 1 、 3As shown in the figure: The bandaging mechanism 3 includes a second support rod 301 slidably arranged in the first chute 101 respectively. The upper ends of the two second support rods 301 are respectively connected to both sides of the lower part of the second housing 302. One side of the second housing 302 is provided with a first motor 303 whose output shaft passes through the second housing 302. A second driving gear 304 is arranged on the part of the output shaft of the first motor 303 located inside the second housing 302. The middle part of the second housing 302 is installed with a rotating block 305 with a hollow structure in the middle through a bearing. A driven gear 306 is arranged in the middle of the outer edge of the rotating block 305. A number of mounting rods 307 for mounting the crepe paper rolls are arranged on one side of the rotating block 305 at equal angles. A baffle 308 is installed at the end of the mounting rod 307 through threads. After passing the lead wire through the middle of the rotating block 305 and fixing both ends to the two fixing mechanisms 2, by installing the crepe paper roll on the mounting rod 307, then attaching the end of the crepe paper to the lead wire, and then starting the first motor 303, under the action of the second driving gear 304 and the driven gear 306, the rotating block 305 will rotate, so that the crepe paper can be wound around the lead wire to bandage the lead wire.

[0020] According to Figure 1 As shown in the figure: The driving mechanism 4 includes a bidirectional lead screw 401 rotatably arranged in the middle first chute 101 and threaded through the two first support rods 201, and a unidirectional lead screw 402 rotatably arranged in the first chutes 101 on both sides and passing through the second support rod 301. A number of second motors 403 are arranged on one side of the base 1 and are respectively key-connected to the bidirectional lead screw 401 and the unidirectional lead screw 402. When the bidirectional lead screw 401 is driven to rotate by starting the second motor 403, the two fixing mechanisms 2 on both sides can be moved closer to or away from each other, so that the fixing mechanisms 2 can fix the two ends of lead wires of different lengths. When the unidirectional lead screw 402 is driven to rotate by starting the second motor 403, the position of the bandaging mechanism 3 can be changed, so that bandaging at different positions of the lead wire can be achieved.

[0021] Principle of the utility model: When in use, first drive the bidirectional lead screw 401 to rotate by starting the motor two 403, so that the two fixing mechanisms 2 approach or move away from each other until the distance between the two fixing mechanisms 2 is the same as the length of the lead wire. Then pass the lead wire through the middle of the rotating block 305 and place the two ends respectively in the middle of a number of clamping claws 205 of the two fixing mechanisms 2. Next, rotate the control rod 204. Under the cooperation of the first driving gear 209 and the face gear 207, the coupling 203 will rotate. Under the action of the groove 208 and the boss 210, the number of clamping claws 205 will approach each other to fix the lead wire. Then start the motor two 403 to drive the unidirectional lead screw 402 to rotate, so that the bandaging mechanism 3 moves to one end of the lead wire. Then install the crepe paper roll on the mounting rod 307 and stick the end of the crepe paper to the lead wire. Then start the motor one 303 and the motor two 403 that drives the unidirectional lead screw 402. Under the action of the second driving gear 304 and the driven gear 306, the rotating block 305 will rotate, so that the crepe paper can be wound around the lead wire to bandage the lead wire. The motor two 403 drives the unidirectional lead screw 402 to rotate, so that the bandaging mechanism 3 moves to gradually bandage from one end to the other end of the lead wire. At the same time, according to the need, control the rotation speed of the unidirectional lead screw 402 to achieve single-time bandaging with different thicknesses. In this way, the bandaged lead wire has high efficiency and good tightening degree.
