Description

[0001]
[Industrial application fields]
In the present invention, when the strand fed from the extruder passes between the upper roll and the lower roll having driving in the take-up machine, the rotary rotation is driven by both the upper roll and the lower roll to be driven. The present invention relates to an apparatus for adjusting the feeding / withdrawing speed of a strand.
[0002]
[Prior art]
Conventionally, the strand passing through this kind of take-up machine reaches the take-up machine via the extruder, but when it is fed between the upper and lower rolls of this take-up machine, the upper roll only serves as a guide roll, In general, a roll plays a driving role. Therefore, the strands passing between the upper and lower rolls having different rotations have a problem that they cannot be drawn out and fed out at an average speed due to sliding or the like.
[0003]
[Problems to be solved by the invention]
As described in the prior art, the strands that pass through the take-up machine have a disadvantage that the speed is not uniform, and therefore, the cutting by the pelletizer is totally uneven and many defective products are generated.
The present invention has been made to solve the above-mentioned drawbacks. The object of the present invention is to take up the strands fed from the extruder in the take-up machine, and to interpose an upper roll and a lower roll to be driven with a plurality of intermediate pulleys. Are simultaneously driven and rotated, and the strands are sent to the pelletizer at a stable average speed by the upper and lower rolls.
[0004]
[Means for Solving the Problems]
In order to achieve the above object, according to the present invention, the take-up machine body located in front of the pelletizer is provided with a side frame opposite to the upper part, a lower roll is installed on the side frame, and a belt is attached to one end of the lower roll. Install a drive pulley with a shaft and an interlocking pulley on the other end. A pressing arm for the upper roll is installed on the opposing arm mounting plate connected to the side frame. The upper roll is installed on the upper arm of the upper roll. The upper roll has an interlocking coil spring at one end, and a rotating pulley is pivotally attached. A plurality of intermediate pulleys are interlinked with the interlocking pulley, and the upper roll and the lower roll are driven simultaneously in conjunction with the rotating pulley of the upper roll.
[0005]
[Action]
Explaining the operation of the take-up machine configured as described above, the strand (25) sent from the extrusion molding machine is drawn between the lower roll (3) and the upper coat roll (4), and is driven when sent out. The lower roll (3), which is the main drive, is rotated by the rotation of the pulley (6), and the interlocking pulley (8) connected thereto is also rotated, so that the intermediate pulley (13) and the intermediate pulley interlocked with the interlocking pulley (8) The rotation is transmitted to the rotating pulley (12) of the upper roll (4) through the pulley (14) to rotate the upper roll (4). Accordingly, the strand (25) can be fed out at a stable speed by the rotation of both the lower roll (3) and the upper roll (4). Also, the large and small diameter of the strand (25) is loosely linked by the movement of the holding arms (17) and (17) of the upper roll (4), and the speed of feeding and pulling is adjusted at an average speed. Supply to the pelletizer.

【Example】
An embodiment of the present invention will be described with reference to the drawings. A take-up machine body (1) is located between an extruder and a pelletizer (not shown). As shown in FIG. 1, the take-up machine main body (1) is movably installed, and is connected to the upper side frames (2) and (2) and the side frames (2) and (2) which are opposed to each other on the upper roll (4). The arm mounting plates (16) and (16) are mounted. Next, the lower roll (3) is installed on the side frames (2) and (2) by the shaft (5), and the upper roll (4) is installed on the arm mounting plates (16) and (16). It is. Next, the shaft portion (5) of the lower roll (3) is provided with a drive pulley (6) having a drive belt (7) laid on one end and a side frame (2) on the other end. An interlocking pulley (8) made of rubber or the like is attached to the outside of the shaft.
The upper roll (4) is rotatably supported at the tip end of the holding arms (17) (17) installed inside the arm mounting plates (16) (16). The upper roll (4) has an interlocking coil spring (10) on one end and an extension of the shaft (9) of the upper roll (4), and an end made of rubber or the like on the end of the upper roll (4). A rotating pulley (12) is axially attached. Further, a pulley mounting plate (11) is provided inside the rotary pulley (12), and an intermediate pulley (14) made of rubber or the like is mounted on the mounting plate (11) via a pressing spring (18). It is set up. The intermediate pulley (14) is interlocked with the rotating pulley (12). Further, an intermediate pulley (13) made of rubber or the like for rotating both pulleys is interposed between the interlocking pulley (8) and the intermediate pulley (14). Next, an elevating adjustment body (20) having an adjustment spring (19) of the upper roll (4) is installed at the rear end of the pressing arm (17). The take-up machine main body (1) is provided with a support column (21) in a part of the upper part, and the support column (21) is provided with an elevating rod (22) that presses the slack of the strand (25). 22) has a pressing roll (23) at the lower end. Reference numeral (24) is a guide roll, which is arranged side by side. (26) shows a prime mover that operates a drive belt (7) installed inside the take-up machine main body (1).

【The invention's effect】
According to the strand feeding / pulling-in speed adjusting device of the present invention configured as described above, the average is stably compared with the one that feeds and pulls in by driving only the lower roll described in the prior art. The effect of being able to guide and guide at a high speed and the effect that the upper roll and the lower roll can be actuated simultaneously in the feed direction by a driving operation from one place can save power significantly. And since an upper roll and a lower roll rotate simultaneously, there exists an effect which the strand which passes can be sent out smoothly and lightly, without slipping between upper and lower rolls, or wearing. In addition, since a pressing spring is installed in one of the plurality of intermediate pulleys provided between the interlocking pulley and the rotating pulley, the intermediate pulleys are always in pressure contact with each other and reliably interlocked from the lower roll to the upper roll. Each pulley has the effect of moving and joining regardless of the large and small gaps of the strand. Further, since the interlocking coil spring is interposed between the upper roll and the rotating pulley, there is no fear of breakage due to the buffering action, and there is an effect of ensuring the movement.
