Description

Technical Field

[0001] The utility model relates to the technical field of cable production, in particular to a conveying and pressure supply device for a cable production line. Background Art

[0002] At the end of cable production, the cable needs to be rolled up to form a cable roll. Existing cable reeling devices directly reel the cable when in use, lacking the tensioning function of the cable, resulting in the reeled cable not being tight enough and easily becoming loose, causing the cable roll to be too large, which is not conducive to storage and transportation. Therefore, in view of the above situation, it is urgent to develop a conveying and pressing device for a cable production line that is convenient for tensioning the cable and prevents the reeled cable from becoming loose, so as to overcome the shortcomings in current practical applications and meet current needs.

[0006] Preferably: the clamping mechanism includes: a threaded sleeve, a toggle rod, a threaded rod, a lifting frame and a clamping roller, the threaded sleeve is rotatably connected to the bracket, a plurality of toggle rods are fixed to the outside of the threaded sleeve, a threaded rod passing through the threaded sleeve is installed inside the threaded sleeve, the bottom of the threaded rod is fixed to the lifting frame, and a clamping roller is rotatably connected inside the lifting frame.

[0010] Preferably, a limiting groove for inserting the anti-rotation rod is provided at the end of the supporting roller.

[0011] The beneficial effects of the utility model are as follows: the cable production line uses a conveying and pressing device. When in use, the cable is passed between the support roller and the pressing roller, and the cable is passed from under the pressing roller, and the front end of the cable is wound onto the winding device. At this time, the anti-rotation rod is inserted into the support roller so that the support roller cannot rotate. Then, the toggle rod is turned by hand to drive the threaded sleeve to rotate, and the threaded sleeve is rotated to drive the threaded rod, the lifting frame and the pressing roller to move downward, so that the pressing roller presses the cable onto the support roller. Then, the squeezing rod is driven downward by the first electric telescopic rod, the swing plate is driven downward by the squeezing rod, and the pressing wheel is driven downward by the swing plate The cable is squeezed by the movement, so that the cable is tensioned. Since the support roller is restricted by the anti-rotation mechanism and cannot rotate at this time, when the pre-tensioning mechanism tensions the cable, the clamped cable between the support roller and the clamping mechanism is difficult to move, so that the pre-tensioning mechanism tensions the cable, so that the cable from the support roller to the pre-tensioning mechanism and then to the reeling device is tensioned. After the cable is tensioned, the reeling device is started to reel the cable.

In summary, the utility model is convenient for tensioning the cable and prevents the reeled cable from becoming loose. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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 are within the scope of protection of the utility model.

[0021] Specific examples are given below.

[0022] See also Figure 1 to Figure 6In the embodiment of the utility model, a conveying and pressing device for a cable production line includes a base 1, a winding device 2, a bracket 3, a pre-tightening mechanism 4, a supporting roller 5, a clamping mechanism 6 and a rotation-stopping mechanism 7. The right end of the base 1 is equipped with a winding device 2 (the winding device 2 is composed of a motor, a winding drum and other components. During operation, the motor drives the winding drum to rotate to wind the cable). The bracket 3 is fixed on the base 1, and the supporting roller 5 is rotatably connected in the bracket 3. A clamping mechanism 6 is installed on the bracket 3 above the supporting roller 5, and a rotation-stopping mechanism 7 inserted into the supporting roller 5 to limit its rotation is installed on the side of the bracket 3. The pre-tightening mechanism 4 is installed on the right side of the bracket 3. When in use, the cable is passed between the supporting roller 5 and the clamping mechanism 6, and the cable is passed from the bottom of the pre-tightening mechanism 4, and the front end of the cable is wound around the winding device 2. At this time, the rotation-stopping mechanism 7 is inserted into the supporting drum 5 so that the supporting drum 5 cannot rotate, and then the cable is pressed onto the supporting drum 5 by the clamping mechanism 6, and then the pre-tensioning mechanism 4 is moved down so that the pre-tensioning mechanism 4 tensions the cable. Since the supporting drum 5 is restricted and cannot rotate by the anti-rotation mechanism 7 at this time, when the pre-tensioning mechanism 4 tensions the cable, the clamped cable between the supporting drum 5 and the clamping mechanism 6 is difficult to move (at this time, the cable can only slide relative to the supporting drum 5, and needs to overcome a greater friction force), so that the pre-tensioning mechanism 4 tensions the cable, so that the section of the cable from the supporting drum 5 to the pre-tensioning mechanism 4 and then to the winding device 2 is tensioned. After the cable is tensioned, the winding device 2 is started to wind the cable, and at the same time, the anti-rotation mechanism 7 is separated from the supporting drum 5, so that the supporting drum 5 can rotate, so that the cable is tightly wound around the winding device 2.

[0023] The preload mechanism 4 includes: a swing plate 401, a pressure wheel 402, a pin 403, a sleeve 404, a first electric telescopic rod 405, a squeeze rod 406 and a spring 407. There are two swing plates 401, and a pressure wheel 402 is rotatably connected between the two swing plates 401. A pin 403 is fixed to the upper end of each swing plate 401, and each pin 403 is rotatably connected to a sleeve 404. The sleeve 404 is fixed to the bracket 3, and each swing plate 401 is installed with a The spring 407 is connected to the bracket 3, the first electric telescopic rod 405 is fixed on the bracket 3, and the output end of the first electric telescopic rod 405 is fixed to the squeezing rod 406, and the squeezing rod 406 is located on the upper side of the swing plate 401. When in use, the cable is passed through the lower side of the pressing wheel 402, and then the squeezing rod 406 is driven downward by the first electric telescopic rod 405, and the swing plate 401 is driven to swing downward by the squeezing rod 406, and the pressing wheel 402 is driven to swing downward by the swing plate 401 to squeeze the cable, so that the cable is tensioned.

[0024] The clamping mechanism 6 includes: a threaded sleeve 601, a toggle rod 602, a threaded rod 603, a lifting frame 604 and a clamping roller 605. The threaded sleeve 601 is rotatably connected to the bracket 3. A plurality of toggle rods 602 are fixed to the outside of the threaded sleeve 601. A threaded rod 603 passing through the threaded sleeve 601 is installed inside the threaded sleeve 601. The bottom of the threaded rod 603 is fixed to the lifting frame 604. Two limiting rods 6041 passing through the bracket 3 are fixed on the lifting frame 604. The positioning rod 6041 is slidably connected to the bracket 3, and the movement of the lifting frame 604 and the threaded rod 603 is restricted by the limiting rod 6041 so that they cannot rotate but can only move in a straight line. A clamping roller 605 is rotatably connected inside the lifting frame 604. When in use, the toggle rod 602 is rotated by hand to drive the threaded sleeve 601 to rotate, and the threaded sleeve 601 rotates to drive the threaded rod 603, the lifting frame 604 and the clamping roller 605 to move downward, so that the clamping roller 605 presses the cable onto the supporting roller 5.

[0025] The anti-rotation mechanism 7 includes: a second electric telescopic rod 701 and a anti-rotation rod 702, the second electric telescopic rod 701 is fixed to the side of the bracket 3, the output end of the second electric telescopic rod 701 is fixed to the anti-rotation rod 702, the anti-rotation rod 702 has a rectangular shape, and the end of the support roller 5 is provided with a limiting groove 501 for inserting the anti-rotation rod 702. When the second electric telescopic rod 701 drives the anti-rotation rod 702 to be inserted into the limiting groove 501, due to the limitation of the rectangular shape of the anti-rotation rod 702, the support roller 5 cannot generate relative rotation with the anti-rotation rod 702, thereby making the support roller 5 unable to rotate.

[0026] Working principle: The cable production line uses a conveying and pressing device. When in use, the cable is passed between the support roller 5 and the pressing roller 605, and the cable is passed from under the pressing wheel 402, and the front end of the cable is wound onto the winding device 2. At this time, the anti-rotation rod 702 is inserted into the support roller 5 so that the support roller 5 cannot rotate. Then, the toggle rod 602 is turned by hand to drive the threaded sleeve 601 to rotate, and the threaded sleeve 601 is rotated to drive the threaded rod 603, the lifting frame 604 and the pressing roller 605 to move downward, so that the pressing roller 605 presses the cable onto the support roller 5. Then, the squeezing rod 406 is driven downward by the first electric telescopic rod 405, and the swing plate 401 is driven downward by the squeezing rod 406, and the pressing wheel 402 is driven upward by the swing plate 401. The downward swing squeezes the cable, causing it to be tensioned. Since the support roller 5 is restricted by the anti-rotation mechanism 7 and cannot rotate at this time, when the pre-tensioning mechanism 4 tensions the cable, the clamped cable between the support roller 5 and the clamping mechanism 6 is difficult to move, so that the pre-tensioning mechanism 4 tensions the cable, thereby tensioning the section of the cable from the support roller 5 to the pre-tensioning mechanism 4 and then to the reeling device 2. After the cable is tensioned, the reeling device 2 is started to reel in the cable. At the same time, the anti-rotation rod 702 is separated from the support roller 5, so that the support roller 5 can rotate (the movement of the cable will drive the support roller 5 and the clamping roller 605 to rotate), so that the cable in the tensioned state is tightly wound around the reeling device 2 to prevent the reeled cable from becoming loose.
