Embodiment Construction

[0013] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0014] refer to figure 1 As shown, the counterweight tension roller mechanism of the present invention includes: a machine platform 1 provided with a placement hole, a bearing 2 arranged in the placement hole of the machine platform, a tension roller 3, a friction adjustment lever 4 fixedly connected below the roller shaft 301, The adjustment box 5 is sleeved on the outer side of the bottom end of the friction adjustment rod 4 .

[0015] The roller shaft 301 of the tension roller 3 is sleeved in the bearing 2, and it forms a vertical rotation connection with the machine table 1 through the bearing 2, and the outer ring of the bearing 2 is fixedly connected with the machine table 1. The roller shaft 301 and the inner ring of the bearing 2 form a vertical sliding connection, the top of the adjustment box 5 is formed with an annular first s...

Abstract

The invention discloses a counterweight tension roller mechanism, which comprises a stand, a bearing, a tension roller, a friction regulating rod and a regulating box. A roller shaft is vertically in sliding connection with an inner circle of the bearing. A first cambered step is formed at the top end of the regulating box. The radius of the top end of the friction regulating rod is smaller than that of the roller shaft, and a second cambered step is formed between the top end of the friction regulating rod and the roller shaft. A helical spring is arranged outside the friction regulating rod between the first and second steps. The friction regulating rod is divided into an upper loosened section and a lower friction section. The radius of the loosened section is smaller than that of the friction section. A plurality of layers of friction belts are arranged below the first step of the regulating box. Each layer of friction belt comprises a plurality of freely rolling steel balls which are uniformly distributed in a circumferential direction. The counterweight tension roller mechanism has the beneficial effects that the number of the friction belts contacting with the friction regulating rod is changed by changing gravity, and the torque of the roller shaft is regulated through friction force, so that tension is regulated; and the counterweight tension roller mechanism is simple and practical in structure, and the conventional equipment can be favorably improved.

Description

technical field [0001] The invention relates to a tension control mechanism, in particular to a counterweight tension roller mechanism for yarn laying. Background technique [0002] With the development of the economy, people's demand for textile products is increasing. The improvement of the equipment used for textile has greatly promoted the efficiency of textile production. In textile production, yarn unwinding from the bobbin is an essential production link. In the past yarn unwinding equipment, the mode of free yarn unwinding is often adopted, that is, the change of yarn tension during the unwinding process is not considered. The rotatable yarn roller on the bobbin splicing machine is directly pulled by constant force to realize yarn release. [0003] However, in recent years, along with the appearance of precisely controlled weaving equipment, it is often desired that the yarn maintains a constant tension during the yarn unwinding process. Nowadays, servo motors and...
