Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1 to Figure 3 As shown, a positive upper warp let-off structure includes two left and right wall panels 2, an upper warp beam 1, a fixed beam 3, an elastic reset mechanism 4, a swing rod 6 and a rotating beam 8, and the upper warp beam 1 is arranged on the wall panel 2. The upper end and the two ends of the fixed beam 3 are rotated and matched with the left and right wall panels 2 respectively. The elastic reset mechanism 4 is connected between the fixed beam 3 and the wall panel 2. The fixed beam 3 is connected with the swing rod 6 through the swing arm, and the rotating beam 8 Rotation is arranged on the wallboard 2. It also includes a swing rod driving device, which is connected to the fixed beam 3 in transmission. The swing rod driving device is an electric cylinder 9, and the electric cylinder 9 includes a cylinder body 94, a ...

Abstract

The invention relates to an active type upper let-off structure which comprises a left wall plate, a right wall plate, a top beam, a fixed beam, elastic reset mechanisms, a swing rod and a rotating beam. The top beam is arranged at the upper ends of the wall plates. The two ends of the fixed beam are rotationally matched with the left wall plate and the right wall plate respectively. The elastic reset mechanisms are connected between the fixed beam and the wall plates. The fixed beam is connected with the swing rod through a swing arm. The rotating beam is rotationally arranged on the wall plates. The upper let-off structure further comprises a swing rod driving device connected with the fixed beam in a transmission mode. According to the active type upper let-off structure, the fixed beamcan be driven by the swing rod driving device to actively work when and after fluffing, and therefore the swing rod actively relaxes during fluffing, the tension of warp does not change before and after fluffing, and it is avoided that the warp is pulled back after fluffing.

Description

technical field [0001] The invention relates to a towel machine, in particular to a positive upper let-off structure. Background technique [0002] see Figure 4 As shown, the existing towel machine is provided with an upper warp beam 1, a fixed beam 3, an elastic reset mechanism 9, a swing bar 8 and a rotating beam 10, the fixed beam is connected with the swing bar through a swing arm 31, and the fixed beam is rotatably arranged on the towel machine. On the wallboard 7, an elastic reset mechanism is connected between the fixed beam and the wallboard, and the function of the elastic reset mechanism is to drive the fixed beam to swing toward a certain state. The swivel beam is swivelly arranged on the wallboard. The warp yarn J output by the upper warp beam is sent to the weaving mechanism of the towel machine after passing through the fixed beam, the rotating beam and the pendulum in turn. When the towel machine is fluffing, the reed hits the front to pull the warp yarn, a...
