Description

Technical Field

[0001] The utility model relates to the technical field of wire material pay-off equipment, in particular to a power line transmission device. Background Art

[0002] Power cords are a common component of electrical appliances in daily life and work. One end of the electrical plug is generally connected to the external power supply, and the other end is connected to the appliance through the power cord. A large number of power cords are required in the production process of electrical plugs, and the power cords are generally transported in the form of coils. Modern technology generally connects the power cord on the reel directly to the equipment for producing plugs for production. However, in fact, when producing plugs, it is often difficult to maintain a balance between the output speed of the power cord and the unwinding speed of the reel. As a result, the output power cord is broken or the power cord is loose or tangled, which greatly affects the production efficiency. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0023] The specific implementation of the utility model will be described below in conjunction with the accompanying drawings:

[0024] like Figures 1 to 5 As shown, a power line transmission device includes a base 1, a reeling mechanism 2 and a wire rod 3. The unreeling mechanism 2 is provided at one open end of the base 1, and the wire rod 3 is provided at the other end. The bottom surface of the base 1 is provided with a plurality of evenly distributed support feet 11, and the side of the support feet 11 in contact with the ground is provided with an anti-skid pad 111. The device is prone to vibration during operation, and the anti-skid pad 111 can keep the position stable and the device does not shift with the vibration. The wire rod 3 includes an upper wheel group 31, a movable plate 32 and a lower wheel group 321. The upper wheel group 31 is provided at the top of the wire rod 3, the movable plate 32 is located below the upper wheel group 31 and is slidably connected to the wire rod 3, and the lower wheel group 321 is provided on the movable plate 32. The wire rod 3 is provided with a plurality of guide posts 34, the guide posts 34 pass through the movable plate 32, and the two ends are fixedly connected to the top of the wire rod 3 and the base 1 respectively. The movable plate 32 can move up and down along the guide posts 34, and the plurality of guide posts 34 are used to ensure that the movable plate 32 maintains the degree of freedom in the vertical direction during the movement. The guide column 34 is provided with springs 322 above and below the moving plate 32. The lower ends of the springs 322 are fixedly connected to the base 1 and the moving plate 32, respectively, and the upper ends are provided with baffles 323. If the moving plate 32 moves up too high or moves down too low, it may collide with the top or bottom plate of the wire rod 3. The springs 322 play a buffering role between the moving plate 32 and the top and bottom plate of the wire rod 3, and the baffles 323 are conducive to evenly distributing the impact potential energy to the springs 322.

[0025] An orientation mechanism 12 is provided on the base 1 between the unwinding mechanism 2 and the wire rod 3. A pair of pinching wheels 121 are provided on the top of the orientation mechanism 12, and the power cord passes through the gap between the pinching wheels 121 and is transported to the wire rod 3. Under the action of the pinching wheels 121, when the power cord is guided in a directional manner, excessive friction between the power cord and the orientation mechanism 12 is prevented.

[0026] The unwinding mechanism 2 is responsible for unwinding the wire, and the wire rod 3 is responsible for outputting the wire. The power wire is unwound from the unwinding mechanism 2 and transported to the wire rod 3 by the guiding action of the directional mechanism 12. The power wire is wound between the upper wheel group 31 and the lower wheel group 321. When the unwinding speed is greater than the output speed, the length of the power wire between the upper wheel group 31 and the lower wheel group 321 decreases and slides upward; when the unwinding speed is less than the output speed, the length of the power wire between the upper wheel group 31 and the lower wheel group 321 increases and slides downward, thereby adjusting the balance of the output and unwinding wire.

[0027] The unwinding mechanism 2 includes a reel 21, a screw 22 and a motor 23. The screw 22 passes through the support seat 14 on the base 1 and is threadedly connected to the support seat 14. The screw 22 passes through the rotating shaft of the reel 21. The side of the reel 21 away from the support seat 14 is fixedly connected to the output end of the motor 23 by a fastener. The motor 23 drives the reel 21 to rotate around the screw 22, thereby releasing the power cord. A hand wheel 221 is provided at one end of the screw 22 away from the motor 23. The hand wheel 221 is turned to rotate the screw 22, thereby controlling the length of the screw 22 screwed into the support seat 14. A top screw 141 is provided on the support seat 14, and the top screw 141 passes through the support seat 14 and contacts the slide groove 222 on the screw 22. When it is necessary to remove the reel 21, the fastener between the reel 21 and the motor 23 is released. The screw rod 22 is screwed out of the support seat 14, and the reel 21 is pushed out from the open side of the base 1; when replacing a new reel 21, the screw rod 22 is screwed into the reel 21, and after the reel 21 is moved to a suitable position, the screw rod 22 is fixed by the top screw 141. A positioning plate 24 is provided between the reel 21 and the support seat 14, and the screw rod 22 passes through the positioning plate 24. One side of the positioning plate 24 contacts the side surface of the reel 21, and the other side is provided with a locking mechanism. The locking mechanism includes a positioning bolt 224, one end of which passes through the positioning bolt 224 and contacts the bottom surface of the slide groove 222. The length of the reel 21 will be different depending on the model. The positioning plate 24 can slide along the length direction of the screw rod 22 and lock the position of the positioning plate 24 on the screw rod 22 by the positioning bolt 224. According to the length of the reel 21, adjust the position of the positioning plate 24 on the screw 22, rotate the screw 22, and when the screw 22 is screwed into the support seat 14, the positioning plate 24 limits the side of the reel 21 away from the motor 23, so as to facilitate the positioning between the reel 21 and the motor 23. A plurality of rollers 223 arranged in a circle are provided on the positioning plate 24. The rollers 223 are used to make the positioning plate 24 roll in contact with the side of the reel 21, so as to reduce the friction between the positioning plate 24 and the reel 21. A plurality of position sensors 33 with uniform intervals are provided in the length direction of the wire rod 3, and the position sensors 33 are electrically connected to the motor 23 through a control circuit. An electric control box 13 is provided on one side of the wire rod 3, and the position sensor 33 transmits the information of the moving position of the moving plate 32 to the control circuit in the electric control box 13. The electric control box 13 controls the rotation speed of the motor 23, thereby achieving a balance between the speed of balanced wire output and wire release.

[0028] The working principle of the specific embodiment of the utility model is as follows: the motor 23 drives the reel 21 to rotate and release the power cord. Under the action of the directional mechanism 12, the power cord is transported to the upper wheel group 31 on the wire rod 3. The power cord is wound between the upper wheel group 31 and the lower wheel group 321, and then discharged from the side of the wire rod 3 away from the unwinding mechanism 2. When the unwinding speed is inconsistent with the discharge speed, the length of the power cord wound between the upper wheel group 31 and the lower wheel group 321 changes, and the moving plate 32 moves up and down along the guide column 34 accordingly.
