Abstract

The utility model provides a micro-adjustable swinging arm of a high-speed tricot machine, which comprises a needle-bed bracket, a needle-bed bracket eccentric core, a connector, a connection pin shaft, a pull rod, a swinging shaft and a swinging arm body, wherein the pull rod is fixedly connected with the connector, the connector is fixedly connected with the needle-bed bracket eccentric core through the connection pin shaft, the needle-bed bracket eccentric core is sleeved inside a hole on the needle-bed bracket, and the side surface of the needle-bed bracket eccentric core is at least provided with a hole. The swinging shaft passes through the end part of the swinging arm body so as to play the role in supporting the swinging arm. The micro-adjustable swinging arm is convenient and simple to adjust, the height of the needle-bed bracket of the swinging arm is easy to control, bad influence of the machine on the needle bed and the needle-bed bracket can be eliminated, the service lifeof the needle bed and the needle-bed bracket is prolonged, and the quality of the fabric product is guaranteed.

Description

The fine-tuning swing arm of a kind of high speed warp knitting machine

Technical field

The utility model relates to a kind of swing arm, relates to the fine-tuning swing arm of a kind of high speed warp knitting machine specifically.

Background technology

Swing arm is one of vitals of warp knitting machine, and the needle-bar bracket is arranged in the swing arm, can drive needle-bar and do motion clocklike, finishes the lopping action by the requirement of product.At present, the swing arm of warp knitting machine is to be connected by the direct-connected traditional approach of clamping screw with connector, if the height of the needle-bar bracket of swing arm is improper, want the height of metering needle bed bracket seat, have only by the nut that unscrews the clamping screw between swing arm and the connector and regulate, regulate and screw clamping screw again after suitable, this method is not only regulated trouble, and owing to the bad control of amplitude that swing arm needle-bar bracket is regulated, be easy to make needle-bar and needle-bar bracket to be out of shape after the machine works, greatly reduce the life-span of needle-bar and needle-bar bracket, and influenced the quality of fabric product.

The utility model content

For addressing the above problem, the utility model provides a kind of high speed warp knitting machine fine-tuning swing arm, and this device is easy to adjust, can effectively reduce the impulsive force of machine works to the needle-bar bracket.

The utility model is for achieving the above object, and the technical scheme of taking is:

The fine-tuning swing arm of a kind of high speed warp knitting machine, comprise needle-bar bracket, needle-bar bracket core shift, connector, connection bearing pin, pull bar, balance staff, swing arm body, described pull bar is fixedlyed connected with connector, the connector utilization connects bearing pin and fixedlys connected with needle-bar bracket core shift, needle-bar bracket core shift is socketed in the hole on the needle-bar bracket, has a hole at least on described needle-bar bracket core shift side.

Described balance staff passes the end of swing arm body, and swing arm is played a supporting role.

Reach in the hole on the needle-bar bracket core shift side by specific purpose tool during adjusting, turn needle-bar bracket core shift, then needle-bar bracket core shift drives swing arm and rotates together, regulates the height of swing arm needle-bar bracket according to actual conditions.Because of swing arm is the minor rotation of doing around balance staff, this rotatory force is that the edge is the tangential direction of the circle at center with the balance staff, according to the parallelogram of forces rule power is decomposed along level, vertical direction, promptly this rotatory force makes the needle-bar bracket of swing arm that moving up or down be arranged, thereby regulates the height of the needle-bar bracket of swing arm.

The utility model is easy to adjust and simple, be easy to control the height of the needle-bar bracket of swing arm, has eliminated machine operation to the harmful effect that needle-bar and needle-bar bracket bring, and has prolonged the life-span of needle-bar and needle-bar bracket, guarantees the quality of fabric product.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the decomposing schematic representation of swing arm body around the minor rotation power F of balance staff.

Wherein: 1 is that needle-bar bracket, 2 is that needle-bar bracket core shift, 2-1 are that hole, 3 is that connector, 4 is that pull bar, 6 is that balance staff, 7 is that swing arm body, 7-1 are the end for connecting bearing pin, 5.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further.

As shown in Figure 1, the fine-tuning swing arm of a kind of high speed warp knitting machine comprises needle-bar bracket 1, needle-bar bracket core shift 2, connector 3, connects bearing pin 4, pull bar 5, balance staff 6, swing arm body 7.

Pull bar 5 and connector 3 are fixedlyed connected by screw, and connector 3 utilizes and connects bearing pins 4 and fixedlys connected with needle-bar bracket core shift 2, and in the hole that needle-bar bracket core shift 2 is socketed on the needle-bar bracket 1, present embodiment has two hole 2-1 on the side of needle-bar bracket core shift 2.

The end 7-1 that balance staff 6 passes swing arm body 7 plays a supporting role to swing arm.

Can be according to the demand of machine, thereby utilize spanner to reach to turn among the hole 2-1 on needle-bar bracket core shift 2 sides height that needle-bar bracket core shift 2 is regulated swing arm needle-bar brackets 1, swing arm body 7 around the minor rotation power F of balance staff 6 along the decomposition of level, vertical direction as shown in Figure 2.

After warp knitting machine starts running, be delivered to the needle-bar bracket 1 that connector 3, needle-bar bracket core shift 2 pass to swing arm that moves through on the pull bar 5, swing arm body 7 promptly has certain rotation around balance staff 6, make the height of swing arm needle-bar bracket 1 in the changeable principle unanimity of vertical direction with above-mentioned fine setting swing arm body 7, swing arm body 7 makes needle-bar bracket 1 do the motion of regularity up and down around the rotation of balance staff 6, and needle-bar bracket 1 is promptly controlled the regular together motion of needle-bar and finished the lopping action.

The utility model can be convenient the height of adjusting swing arm needle-bar bracket 1, and can well protect needle-bar and needle-bar bracket 1, prolong the service life of needle-bar and needle-bar bracket 1.
