Description

Technical Field

[0001] The utility model relates to the technical field of cable production equipment, in particular to a cable storage rack. Background Art

[0002] Cables are usually used for electric energy transportation or electric signal transmission. The cable production process requires printing on the surface. The traditional printing process requires the simultaneous release and take-up of wires. When the take-up device needs to replace the cable loop, the take-up device must stop working. In order not to affect the work efficiency, it is necessary to add a wire storage rack between the take-up device and the pay-out device. The wire storage rack is used to temporarily store the cables released from the pay-out device when the take-up device stops working, thereby achieving the effect of continuous work. Existing wire storage racks generally achieve the purpose of wire storage by controlling and adjusting the spacing of the wire storage wheels. The wire storage wheels actually used are only provided with a separate wire groove. The cable is easy to slip from the separate wire groove and detach from the wire storage wheel. In this way, the length of the wire storage is limited and the effect of wire storage is not good. Utility Model Content

[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 6 As shown, a cable storage rack includes a frame 1 and a storage wheel group 2. The frame 1 is provided with a storage wheel group 2 on the upper part, and storage wheels are provided at both ends of the storage wheel group 2. A plurality of wire grooves are provided on the storage wheel. The plurality of wire grooves are conducive to increasing the number of winding turns of the cable, increasing the friction contact surface between the cable and the storage wheel, and preventing the cable from falling off the storage wheel due to slipping. The wire groove is a V-shaped groove 23, and the contact surface between the V-shaped groove 23 and the cable is provided with an annular anti-skid pattern 231. The V-shaped groove 23 is adapted to cables of different sizes, and can better prevent the cable from deflecting in the wire groove. The annular anti-skid pattern 231 can further increase the stability of the cable in the wire groove and prevent the cable from radially slipping.

[0025] The wire storage wheel includes a fixed wheel 21 and a moving wheel 22. A mobile bracket 221 is provided at the feeding end of the frame 1. A track 11 matching the mobile bracket 221 is provided on the frame 1. A roller 222 matching the track 11 is provided on the mobile bracket 221. The mobile bracket 221 is in rolling contact with the frame 1. The mobile bracket 221 moves along the track 11 through the roller 222. A position sensor 14 is provided near the end of the track 11. The position sensor 14 is electrically connected to the sound and light alarm of the wire-receiving device. When the mobile bracket 221 is still a short distance away from the end of the track 11, that is, the position of the position sensor 14, the sound and light alarm reminds the staff of the wire-receiving device to resume the wire-receiving operation immediately. A guide wheel 13 is provided at the feeding end. The guide wheel 13 is fixedly connected to the frame 1. Under the guidance of the guide wheel 13, the cable is adjusted in angle and stably wound into the moving wheel 22.

[0026] The mobile bracket 221 is provided with a driving mechanism 3, which includes a driving motor 31 and a screw rod 32. The screw rod 32 passes through the mobile bracket 221 and is threadedly connected to the mobile bracket 221. One end of the screw rod 32 is rotatably connected to the bearing seat 33 on the frame 1, and the other end is fixedly connected to the output end of the driving motor 31 on the frame 1. The bearing seat 33 is provided with an induction switch 331, and the induction switch 331 is electrically connected to the wire supply device, the wire storage rack and the wire take-up device. The driving motor 31 drives the screw rod 32 to rotate, and the screw rod 32 drives the mobile bracket 221 to move along the track 11, and the moving wheel 22 also moves accordingly. When the moving wheel 22 moves and approaches the induction switch 331, it means that the mobile bracket 221 is about to move to the end of the track 11. At this time, the induction switch 331 is triggered, so that the wire supply device, the wire storage rack and the wire take-up device are all shut down to prevent the accumulation of cables and entanglement in the middle link of the wire release device and the wire take-up device.

[0027] The moving wheel 22 is rotatably connected to the mobile bracket 221. The discharging end of the frame 1 is provided with a fixed wheel 21, which is rotatably connected to the frame 1. The frame 1 is provided with a storage motor 211 fixedly connected to the rotation center of the fixed wheel 21. The distance between the moving wheel 22 and the fixed wheel 21 is adjusted by the driving mechanism 3, thereby changing the storage length of the storage rack. The storage motor 211 drives the fixed wheel 21 to rotate slightly faster than the speed of discharging, so that the cable is wound around the storage wheel with tension to prevent the cable from slipping. The mobile bracket 221 and the frame 1 are respectively provided with a pressure roller 4 corresponding to the moving wheel 22 and the fixed wheel 21. The cable passes through the gap between the pressure roller 4 and the storage wheel, so that the cable cannot be adjusted radially over a large range and can only move along the length direction, reducing the probability of the cable jumping out of the storage wheel due to external force or slipping. The pressure roller 4 includes a fixed frame 42 and a roller 41. The fixed frame 42 is fixedly connected to the movable bracket 221 and the frame 1. The other end of the fixed frame 42 is provided with a rotatably connected roller 41. The roller 41 is in rolling contact with the wire storage wheel.

[0028] A tension monitoring mechanism 12 is provided at the discharge end, and the tension monitoring mechanism 12 includes a rotating rod 121, a tension spring 122 and a dynamometer 123. One end of the rotating rod 121 is rotatably connected to the frame 1, and the other end is provided with a V-shaped wheel. One end of the tension spring 122 is connected to the rotating rod 121, and the other end is connected to the dynamometer 123. The cable passes through the top of the V-shaped wheel and then enters the wire-receiving device. The dynamometer 123 is electrically connected to the drive mechanism 3 through the same control circuit. When the wire-receiving device works normally, the cable has a certain tension when it comes out of the discharge end, causing the tension spring 122 to be in a stretched state, and the force value displayed by the dynamometer 123 fluctuates within a certain range. When the wire-receiving device stops, the tension spring 122 is relaxed, and the force value displayed by the dynamometer 123 decreases sharply, thereby transmitting the signal of the wire-receiving device stopping to the control circuit, and the control circuit starts the drive mechanism 3, and the drive mechanism 3 increases the distance between the moving wheel 22 and the fixed wheel 21 to store the cable.

[0029] The working principle of the specific embodiment of the utility model is as follows: the pay-off device pays out the cable, the cable passes through the cable storage rack, and is reeled in the take-up device. The cable passes through the gap between the pressure roller 4 and the cable storage wheel, and is wound between the multiple cable grooves on the moving wheel 22 and the fixed wheel 21. When the take-up device stops, the driving mechanism 3 increases the distance between the moving wheel 22 and the fixed wheel 21, so that the cable storage rack stores the cable, and the pay-off device does not stop during this period.
