KNITTING ROLLER DRIVING DEVICE FOR Circular Knitting Machines {DEVICE FOR DRIVING ROLLER FOR DRAWING KNITTING FABRIC IN CIRCULAR KNITTING MACHINE}

The present invention relates to a knitted fabric take-out roller installed in the winding portion of the circular knitting machine, and more particularly, to improve the structure of the drive device for driving the knitted fabric take-off roller to improve assembly properties and cost, and also to reduce noise. A knitting machine take-out roller driving device for a circular knitting machine.

Generally, as shown in FIGS. 1 and 2, the winding portion of the circular knitting machine is provided with a driving table 2 in the circular table 1, and on both bottom surfaces of the driving table 2, a rotary base 3 and 4 are provided. Are interlocked with each other, and upper and lower portions between the two rotary bases (3) and (4) are provided with a knitted fabric take-out roller (5) and a knitted fabric winding roller (6). A bracket 8 supporting the rotating member 7 is coupled thereto.

Knitting material take-out roller 5 is installed on the upper side of the rotating both sides of the rotary base (3) (4) and overlapped while drawing the fabric woven by the upper knitting device downward with the left and right auxiliary rollers (9) (10) It is formed of double cloth and is wound by the knitted fabric winding roller 6 installed at the bottom of the rotary base (3) (4). At this time, the driving of the knitted fabric take-out roller (5) is to adjust the take-out speed of the knitted fabric according to the desired thickness of the fabric, that is, the number of knitted fabrics to adjust the rotational speed of the knitted fabric take-out roller (5) according to the thickness of the fabric selected Must be converted.

In order to achieve this purpose, it is necessary to easily convert the rotational speed of the knitted fabric take-out roller 5, and at the same time, simplify the machine and enhance driving force.

However, in the conventional knitted fabric take-out roller driving device, as shown in Figs. 1 and 2, the motor 11 is mounted to the inside of the one side rotating table 3, and is built on the motor 11, the small gear 12 (13), the gear 16 of the large, small interlocking gear 14, 15 and the knitting material take-out roller 5 are engaged with each other, and each of the gears 12 to 16 has a different interdental and is simultaneously developed. Since it is composed of a structure that is possibly coupled to the following problems.

That is, the conventional knitted fabric take-out roller driving device has a problem in that assembly is inferior and cost increases since it is composed of a complicated structure in which five gears 12 to 16 are meshed with each other as described above. There was a problem that a large noise occurs due to the friction of each of the gears (12 to 16).

An object of the present invention is to solve the above-mentioned drawbacks, and to improve the structure of the drive device for driving the knitted fabric take-off roller to improve the assembly properties and cost, and also to reduce the noise The present invention provides a knitting machine drawing roller driving device for a circular knitting machine.

In order to achieve the above object, the present invention has a large pulley and a small pulley connected to a timing belt to a knitted pull-out roller and a geared motor, respectively, and a tension adjusting member for adjusting the tension of the timing belt is installed on the outer upper portion of the rotating base. will be.

40: geared motor 50: large pulley

60: pulley 70: timing belt

80: tension adjustment member

Hereinafter, the technical configuration of the present invention in detail according to the accompanying drawings.

3 to 5, the knitting machine take-out roller driving device of the present invention has a rotary base engaged to both bottom surfaces of the driving table installed in the circular table, and the upper and lower rotary pulleys of the rotary knitting machine respectively. 20 and a knitted fabric winding roller are installed, in which the geared motor 40 is mounted to the inside of one side rotating table 30, which is detachably arranged on the knitted fabric taking-out roller 20 and the geared motor 40. Large and small pulleys 50 and 60; Timing belt 70 connecting the large and small pulleys 50 and 60; Tension of the timing belt 70 is installed outside the swivel base 30. It is characterized by the technical configuration that is configured to include a tension adjusting member 80 to adjust the.

Here, the shaft hole 31 is drilled in the upper portion of the rotary base 30, the shaft of the knitted material take-off roller 20 is rotatably fitted into the bearing, the geared motor 40 is mounted on the central portion of the rotary base 30 The motor installation hole 32 is drilled.

The large, small pulleys (50) and (60) are selectively arranged on the shafts of the knitted pull-out roller (20) and the geared motor (40), the present invention is the gear ratio of the large, small pulleys (50) and (60). By appropriately changing the rotation speed of the knitted fabric take-out roller 20 can be obtained in various ways.

On the other hand, in the embodiment of the present invention, the large, small pulleys 50, 60 to replace the sprocket and the timing belt 70 to replace the chain, the chain to the sprocket to drive the pull-out roller 20 Make it clear.

The tension adjusting member 80 is provided with a fixing plate 83 fixed to the swivel base 30 by bolts 82 through the long holes 81 formed at the upper and lower parts thereof, and rotatably installed at the fixing plate 83. The roller 84 is in close contact with the timing belt 70.

Therefore, the tension adjusting member 80 is fixed to the fixing plate 83 with the bolt 82 in the state of properly moving the position of the fixing plate 83 to the left and right through the long hole 81 through the roller 84 The tension of the timing belt 70 can be adjusted appropriately.

In the figure, reference numeral 90 denotes a cover installed to prevent the stand, the small pulleys 50 and 60, the timing belt 70, and the tension adjusting member 80 from being exposed to the outside.

Referring to the overall effect of the present invention configured as described in detail as follows.

When the geared motor 40 mounted on the swivel base 30 is driven, the small pulley 60 built in the geared motor 40 is driven, and the driven pulley 60 drives the timing belt 70. As a result, the knitted fabric pull-out roller 20 is driven through the timing belt 70 and the large pulley 50.

On the other hand, by replacing the air gear 50 and the gear gear 60 installed in the geared motor 40, respectively installed in the punch fabric take-out roller 20, it is possible to change the rotational speed of the knitted fabric winding roller 20 .

Therefore, the present invention has the advantage that the structure is simpler compared to the conventional structure because it drives the knitted fabric take-out roller 20 through the two large, small pulleys (50, 60), and also compared to the conventional parts Since the number can be reduced, the cost of the driving device can be reduced.

In addition, the present invention has a merit that the noise generated during driving is reduced because the large pulleys 50 and 60 are driven by the timing belt 70.

As described above, the present invention has a simple structure and a small number of parts, thereby improving assembly performance and reducing costs, and also reducing the noise.
