Description

Balancing mechanism of needling machine

Technical Field

The utility model relates to a balancing mechanism of a needling machine.

Background

The single-shaft driven needling machine with single connecting rod, single push rod, single needle beam and single needle plate has relatively simple structure, low cost and other advantages, and is widely used in non-woven product manufacturers, but the needling machine has the disadvantage that the rotating speed is usually about 600 plus 800n/min, so the production efficiency is relatively low, and the needling machine belongs to a medium-low speed needling machine.

The common medium-speed needling machine has the problems of large vibration and large left-right shaking, which are caused by the basic structure of a single shaft, the single shaft is usually provided with a balance wheel to offset the upper and lower impact forces, the upper and lower impact forces are difficult to be completely offset in the actual use process, and the left and right inertia forces of the balance wheel cannot be eliminated, so that the main shaft is subjected to the upper and lower impact and the left and right shaking inertia forces, thereby restricting the promotion of needling speed.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve not enough among the prior art and provide a needle loom balance mechanism, can make the needle loom still can demonstrate good equilibrium and guarantee and not produce vibration and horizontal hunting when high-speed, improved the productivity greatly.

In order to achieve the above purpose, the utility model adopts the technical scheme that:

a balance mechanism of a needle machine comprises a main shaft, a needle beam connecting rod, a needle plate beam, a balance weight connecting rod, a balance weight block and a balance weight beam, wherein the needle plate beam is connected with the main shaft through the needle beam connecting rod; the balancing weight is connected with the main shaft through a balancing weight connecting rod, the eccentric direction of the balancing weight connecting rod is opposite to that of the needle beam connecting rod, the balancing weight is connected with the balancing weight beam through a guide device, and the balancing weight can move relative to the balancing weight beam along the guide device.

As a needle loom balance mechanism's an preferred scheme, guider include guide bar and the uide bushing that matches with it, the guide bar lower extreme is fixed with the counter weight roof beam, the uide bushing cover is established on the guide bar and can be followed the guide bar and reciprocated, uide bushing and balancing weight fixed connection. The preferred guider includes two guide bars and two uide bushings, and the guide bar sets up side by side, and the balancing weight is connected with the counter weight roof beam through two guide bars.

As an optimized proposal of the balance mechanism of the needling machine, the main shaft is sleeved with a flywheel.

As a needle loom balance mechanism's an optimal selection scheme, the main shaft on the cover be equipped with the counter weight eccentric wheel, the setting of counter weight eccentric wheel is in flywheel one side.

As a preferred scheme of needle loom balance mechanism, the main shaft be the sectional type, adjacent main shaft passes through the coupling joint.

Drawings

FIG. 1 is a schematic structural view of a balancing mechanism of a preferred needling machine.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

It will be understood that the terms "upper," "lower," "front," "rear," "left," "right," and the like, as used herein, refer to an orientation or positional relationship illustrated in the drawings for convenience in describing the present application and to simplify description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be considered limiting of the present application.

Example 1

As shown in figure 1, the balancing mechanism of the needle machine comprises a main shaft 1, a needle beam connecting rod 2, a needle plate beam 3, a counterweight connecting rod 4, a counterweight block 5 and a counterweight beam 6.

Wherein, the needle plate beam 3 is connected with the main shaft 1 through the needle beam connecting rod 2. The balancing weight 5 is connected with the main shaft 1 through a balancing weight connecting rod 4, and the balancing weight connecting rod 4 is opposite to the eccentric direction of the needle beam connecting rod 2. The balancing weight 5 is fixed with two guide sleeves 7, the guide sleeves 7 are sleeved on the guide rod 8 and can move up and down along the guide rod, the lower end of the guide rod 8 is fixed with the balancing weight beam 6, the balancing weight 5 moves up and down linearly along the guide rod through the guide sleeves 7, the moving direction of the balancing weight is opposite to that of the needle plate beam 3, and the impact force generated by the up-and-down movement of the needle plate beam can be completely offset.

The main shaft is sleeved with a flywheel 9 and a counterweight eccentric wheel 10.

On one side of the flywheel 9, a counterweight eccentric wheel 10 is mounted, which has the same direction and eccentricity as the middle eccentric wheel 11, so that the middle two eccentric wheels are completely opposite to the two eccentric wheels on the two sides, and the left and right inertia forces are completely counteracted.

Meanwhile, a balance wheel in the prior art is directly cancelled, only one flywheel is reserved, the structure is simple, the needling speed is greatly improved, the efficiency is basically close to that of ordinary high-speed needling, the actual equipment cost is also greatly reduced, and the mechanism is accepted by customers in actual application.

Although the embodiments of the present invention have been described in the specification, these embodiments are only for the purpose of presentation and should not be construed as limiting the scope of the present invention. Various omissions, substitutions, and changes may be made without departing from the spirit and scope of the invention.
