Problems solved by technology

This method has the following disadvantages: 1. The frictional resistance is large when starting, and the frictional force becomes smaller when running at high speed, which makes the pay-off tension unstable; 2. It is difficult to ensure the pay-off tension of multiple cradle pay-off reels of the cage winch Consistency
On the other hand, most pay-off shafts use a pair of single-row tapered roller bearings, which also have some problems: first, the use of a pair of single-row tapered roller bearings has a large frictional resistance, which cannot meet the requirements of small tension wires; Although the single-row tapered roller bearing can withstand large axial force, the radial positioning of the shaft is not good. After running for a period of time, there will be a gap in the axial direction, and the shaft will shake, resulting in unstable pay-off tension.

Embodiment 1

[0010] Embodiment 1 is a structure in which the diameter of the pay-off reel is 300mm, and the application range of the tension of the cradle of the cage winch is 5 Newtons to 55 Newtons. Inside the body 14, it is fixed by six M8 inner hexagonal screws, and the fixed pin 12 of the pay-off reel is welded on the head 11 of the pay-off reel, and then fixed on the left end of the cradle pay-off drive shaft 6 by keys and screws, and loaded into 7206 single-row centripetal After the thrust ball bearing, the whole is packed in the bearing sleeve 13, and the 6206 single-row deep groove ball bearing is pressed from the right end, and is fixed by the limit of the circlip. The passive damping disc 1 with a diameter of 98 mm, made of aluminum alloy, with a ring-shaped iron plate embedded and fixed on the end face, is connected with the passive disc fixing seat 8 made of aluminum alloy, and then fixed on the bearing sleeve 13 by M5 inner hexagonal screws. The active damping disc 3, which i...

Embodiment 2

[0012] Embodiment 2 is a structure in which the diameter of the pay-off reel is 500 mm and the application range of the tension of the cage winch cradle is 10 Newton to 180 Newton, wherein: the diameter of the active damping disc 3 and the passive damping disc 1 are 150 mm, and the two discs are adjusted The magnetic pole air gap ranges from 0 to 12mm, and the bearings are 7209 single row radial thrust ball bearings and 6209 single row deep groove ball bearings. Others are the same as embodiment one.

Abstract

Strain of payoff control method and device uses for cage stranger payoff tray of electrical wire and cable equipment. Existing technology adopts strap friction to control the strain of payoff, while the strain of payoff is instability and is disaccord of some cradle payoff tray. It adopts permanent damp technology to adjust magnetic pole air-gap of damp tray and to control strain of payoff. It relates to passive damp tray, active damp tray, accommodate handle, active tray slide cover, transmission shaft, graduation direction mark, fix seat of passive damp tray, bearing, bearing cover and cradle body. Turn accommodate handle to adjust strain of payoff. Accommodate moment is extended constant and dose not change with temperature, time and opposite slide difference speed for non-friction. The whole operation keeps steady strain of payoff and realizes the coherence of strain of payoff to all cradle payoff trays by clearance graduation direction mark.

Description

technical field [0001] The invention relates to wire and cable production equipment technology, in particular to a control method and device for a cradle pay-off reel of a cage winch machine in the wire and cable production equipment. Background technique [0002] In the production process of the wire and cable equipment manufacturing industry and the cable production industry, the pay-off tension of the cage winch cradle pay-off reel is very important. If the pay-off tension is too tight or too loose, it will directly affect the normal operation of production and product quality. Mostly adopted in the industry at present is to utilize the friction method to control the pay-off tension, that is, to adjust the tightness of the belt that drives the rotation of the wheels to control the pay-off tension of the pay-off reel. This method has the following disadvantages: 1. The frictional resistance is large when starting, and the frictional force becomes smaller when running at hi...
