Abstract

The utility model discloses a rapid tape threading tension device used for plate and strip production, comprising a fixed roll and a swinging roll. The fixed roll is arranged on a stand; the swinging roll is arranged on rotating swinging arms; and the fixed roll and the swinging roll are connected with a motor through a clutch. The utility model overcomes the defects that the general tension roll set tap threading device has complex structure, large labor intensity of tape threading, low efficiency, and the like, and can be used on a levelling machine, a straightening and withdrawal machine and other equipment in the steel and the non-ferrous industry.

Description

Wear the belt tension roller arrangement fast

Technical field

The utility model relates to the used belt tension roller arrangement of wearing fast on the equipment such as the planisher, straightening machine of iron and steel, coloured industry.

Background technology

The band of wearing that present stage is used for equipment jockey pulley such as the planisher, straightening machine of strip material production mainly contains two kinds and wears the band mode: a kind of is to adopt the strip material to weld end to end, and weld seam directly passes jockey pulley, and this mode weld seam scratches jockey pulley easily; Another kind is that artificial guided plate band passes jockey pulley, makes like this to wear to be with efficient low, and labour intensity is big.

Summary of the invention

The purpose of this utility model provides a kind of can finishing fast and wears band, increases work efficiency, reduce wear band labour intensity wear the belt tension roller arrangement fast.

The purpose of this utility model is realized by following scheme:

A kind of belt tension roller arrangement of wearing fast comprises a stationary roll and an oscillating roller, and stationary roll is arranged on the frame, and oscillating roller is arranged on the rotatable swing arm; Stationary roll links to each other with driving motor by clutch with oscillating roller.

This wears the belt tension roller arrangement fast is by swing arm oscillating roller to be rotated to wear to be with position and operating position to realize wearing fast band.When wearing band, swing arm rotates to oscillating roller and wears the band position, and the strip material is fed forward to winder by the bottom of unreeling structure from oscillating roller, rolling-up mechanism clamping plate band head, swing arm rotates to the operating position with oscillating roller then, and retaining mechanism is fixed swing arm simultaneously, finishes the band work of wearing.During work, driving motor is connected with oscillating roller, stationary roll by clutch, and the strip material forms required cornerite between oscillating roller and stationary roll, set up tension force, enters normal operating condition.

S jockey pulley group of the present utility model has overcome general jockey pulley group tape threading apparatus complex structure, has worn big, the inefficient defective of band labour intensity, tape threading apparatus of the present utility model does not need to use leader tape can wear band, improved the tape speed of wearing of jockey pulley group greatly, significantly reduced to wear to be with and built the time of opening, reduced the labour intensity of wearing band.

Description of drawings

Fig. 1 be the quick tape threading apparatus of strip material wear the band position view.

Fig. 2 is the operating position schematic diagram of the quick tape threading apparatus of strip material.

The specific embodiment

The disclosed structure of above accompanying drawing is the structure of an embodiment of the utility model.

Among the figure, the 1-stationary roll, the 2-swing arm, the 3-oscillating roller, 4-locks hydraulic cylinder, 5-retaining mechanism, 6-oscillating motor, 7-guide pad (frame), 8-tooth bar, 9-frame.

Consult Fig. 1, Fig. 2, a kind of be used for the production of strip material wear the belt tension roller arrangement fast, it comprises a stationary roll 1 and an oscillating roller 3, stationary roll 1 is installed on the fixed frame 7, oscillating roller 3 is installed on the rotatable swing arm 2, and swing arm 2 can make oscillating roller 3 rotate to the operating position and wear the band position.

Wear the band position as shown in Figure 1, among the figure, unidirectional arrow represents that steel band penetrates direction; The band position is worn in the expression of four-headed arrow top, and the operating position is represented in the below.When locking hydraulic cylinder 4 is separated from retaining mechanism 5 from the operating position, oscillating motor 6 pulls down tooth bar 8, this moment, swing arm 2 rotated up under the drive of tooth bar 8, oscillating roller 3 is in wears the band position, at this moment the strip material can pass between oscillating roller 3 and stationary roll 1, finishes and wears band work fast.

The operating position as shown in Figure 2, among the figure, arrow is represented steel band trend.Finish when wearing band work, oscillating motor 6 upwards pushes away tooth bar 8, this moment, swing arm 2 was rotated down under the drive of tooth bar 8, make oscillating roller 3 be in minimum operating position, lock hydraulic cylinder 4 then and retaining mechanism 5 is upwards lifted lock swing arm 2, the vibration of swing arm when preventing work, this template band material forms cornerite at stationary roll 1 and 3 of oscillating rollers, build and open, enter normal operating conditions.

Claims (1)

1. wear the belt tension roller arrangement fast for one kind, it is characterized in that: it comprises a stationary roll (1) and oscillating roller (3), and stationary roll (1) is arranged on the frame (7), and oscillating roller (3) is arranged on the rotatable swing arm (2); Stationary roll (1) links to each other with driving motor by clutch with oscillating roller (3).
