Description

Technical Field

[0001] The utility model relates to the technical field of cable production, and in particular to an unwinding device for producing cables for new energy vehicles. Background Art

[0002] New energy vehicles rely on electricity to drive and require an efficient power transmission system. Cables are responsible for transmitting electrical energy between key components such as batteries, inverters, and motors to drive the normal operation of the vehicle. These cables must have high conductivity and low resistance to ensure efficient and stable energy transmission.

[0003] The inventor discovered during the process of implementing the utility model:

[0004] A patent document with announcement number CN210312856U discloses a cable unwinding device, which is used to place a reel between two opposite brackets. Since the translation device can move the support shaft along the length direction of the support shaft, the center of the reel can be inserted into the support shaft, and the center lines of the two support shafts coincide, so that the two support shafts are located on both sides of the reel. The two support shafts are rotatably supported on the brackets, and then during the unwinding process of the reel, the support shaft is firmly located on the brackets.

[0005] The solution of the above patent adopts a manual method to drive the reel to rotate, so as to achieve the purpose of unwinding the cable. However, when the device is moved to the unwinding position, the reel is easily rotated accidentally due to the influence of external force, resulting in accidental unwinding of the cable, so that the staff needs to spend extra time and energy to rearrange the cables, reducing work efficiency. In addition, during the process of unwinding and stretching the cable, some parts of the cable may be over-stretched, which will cause changes in the internal structure of the cable, affecting the physical properties and service life of the cable. Summary of the invention

[0010] Furthermore, a reel is disposed inside the first vertical plate, a slot is provided on the outer surface of the reel, and the slot is matched with the plug-in block, and the slot and the plug-in block are located on the same horizontal line.

[0011] Furthermore, the unwinding mechanism includes a rotating motor fixed on one side of the second vertical plate, a bidirectional screw is fixed to the output end of the rotating motor, and the end of the bidirectional screw away from the rotating motor is rotatably connected to the inner side of the other second vertical plate, the outer surface of the bidirectional screw is threadedly connected to a thread block, and the upper surface of the thread block is fixed to the bottom of the U-shaped plate. Starting the rotating motor drives the bidirectional screw to rotate, and the rotation of the bidirectional screw can drive the thread block and the buffer assembly to reciprocate, so that the cable can be unwound evenly.

[0012] Furthermore, a second telescopic spring is sleeved on the outer surface of the telescopic rod, which can increase the elastic force of the telescopic rod.

[0013] Furthermore, mounting grooves are provided on both sides of the fixing plate near the two side plates of the U-shaped plate, balls are arranged inside the mounting grooves, and the outer surfaces of the balls are in contact with the inner sides of the U-shaped plates, which can make the movement of the fixing plate smoother.

DETAILED DESCRIPTION

[0022] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings, but this embodiment should not be understood as a limitation to the present invention.

[0023] The utility model Figures 1 to 4 As shown:

[0024] A reeling device for the production of new energy vehicle cables comprises a base 1, a first vertical plate 5 and a second vertical plate 6 fixed on the upper surface of the base 1, a limit assembly 2 is provided on the upper surface of the base 1, a reeling mechanism 3 is provided on the second vertical plate 6, a buffer assembly 4 is provided on the reeling mechanism 3, and a universal wheel 10 is installed on the bottom surface of the base 1.

[0025] The limiting assembly 2 includes a fixed rod 201 fixed on the upper surface of the base 1 and a plurality of first telescopic springs 203 in an array. The top of the fixed rod 201 is rotatably connected to the limiting block 202. A push plate 204 is fixed to the top of the first telescopic spring 203, and the upper surface of the push plate 204 contacts the bottom surface of the limiting block 202. An insert block 205 is fixed to the upper surface of the push plate 204. A reel 7 is provided inside the first vertical plate 5. A slot 701 is provided on the outer surface of the reel 7. The slot 701 is matched with the insert block 205. The slot 701 and the insert block 205 are located on the same horizontal line.

[0026] By rotating the limit block 202, the limit on the push plate 204 is released. The push plate 204 automatically pushes the plug block 205 to move upward under the compression elastic force of the first telescopic spring 203. The plug block 205 engages with the slot 701 during the movement, thereby fixing the position of the unwinding reel 7 to avoid accidental rotation of the unwinding reel 7 due to the influence of external force.

[0027] The buffer assembly 4 includes a U-shaped plate 401 inverted on the unwinding mechanism 3, a telescopic rod 402 is fixed to the inner top of the U-shaped plate 401, a fixed plate 403 is fixed to the bottom end of the telescopic rod 402, a fixed block 404 arranged opposite to each other is fixed to the bottom surface of the fixed plate 403, a rotating wheel 405 is rotatably connected between the two fixed blocks 404, a second telescopic spring 408 is sleeved on the outer surface of the telescopic rod 402, which can improve the elastic force of the telescopic rod 402, a mounting groove 406 is provided on one side of the fixed plate 403 close to the inside of the U-shaped plate 401, a ball 407 is arranged inside the mounting groove 406, and the outer surface of the ball 407 is in contact with the inner side of the U-shaped plate 401, which can make the movement of the fixed plate 403 smoother;

[0028] Pass one end of the cable through the bottom of the rotating wheel 405. When the tensile force is too large, the cable will push the rotating wheel 405 to move upward, and the rotating wheel 405 will push the fixed plate 403 to squeeze the telescopic rod 402, so that the telescopic rod 402 generates corresponding elastic force to buffer the tensile force on the cable.

[0029] like Figure 1 As shown, the unwinding mechanism 3 includes a rotating motor 301 fixed on one side of the second vertical plate 6, a bidirectional screw rod 302 is fixed to the output end of the rotating motor 301, and one end of the bidirectional screw rod 302 away from the rotating motor 301 is rotatably connected to the inner side of the other second vertical plate 6, and a thread block 303 is threadedly connected to the outer surface of the bidirectional screw rod 302, and the upper surface of the thread block 303 is fixed to the bottom of the U-shaped plate 401;

[0030] A sliding rod 8 is fixed on the inner side of the second vertical plate 6, and the outer surface of the sliding rod 8 is slidably connected to the inner wall of the hole of the threaded block 303, which can guide and support the movement of the threaded block 303. Starting the rotating motor 301 drives the bidirectional screw rod 302 to rotate. The rotation of the bidirectional screw rod 302 can drive the threaded block 303 and the buffer assembly 4 to reciprocate, so that the cable can be unwound evenly.

[0031] like Figure 1 As shown, a controller 9 is installed on the upper surface of the base 1, and the rotating motor 301 is electrically connected to the controller 9 for controlling the start of the rotating motor 301. The model of the controller 9 is Siemens S7-1200.

[0032] The working principle of this utility model:

[0033] When in use, when it is necessary to move to the position where unwinding is required, the limit block 202 is rotated to release the limit on the push plate 204, and the push plate 204 automatically pushes the plug block 205 to move upward under the compression elastic force of the first telescopic spring 203. The plug block 205 engages with the slot 701 during the movement, thereby fixing the position of the unwinding disc 7 to avoid the unwinding disc 7 from accidentally rotating due to external forces. After reaching the position, the push plate 204 is pushed downward to make the push plate 204 lower than the limit block 202, and then the limit block 202 is rotated to complete the push plate 204. The plate 204 is limited, and then one end of the cable passes through the bottom of the rotating wheel 405, and then the rotating motor 301 is started to drive the bidirectional screw rod 302 to rotate. The rotation of the bidirectional screw rod 302 can drive the threaded block 303 and the buffer component 4 to reciprocate, so that the cable can be unwound evenly. When the stretching force is too large, the cable will push the rotating wheel 405 to move upward, and the rotating wheel 405 will push the fixed plate 403 to squeeze the telescopic rod 402, so that the telescopic rod 402 generates corresponding elastic force to buffer the tensile force exerted on the cable.
