Problems solved by technology

In the past, the sending and unwinding belt and the tensioning belt were generally implemented by a pair of roller sets respectively. The roller set generally consisted of a driving roller and a driven wheel that can be attached to the driving roller and separated from the driving roller. The strength of the cylinder is used to cooperate with the tension roller and the active roller gear to achieve tension. The structure is relatively complicated, and the frequency of work failures during packaging is high.

Embodiment Construction

[0014] Refer to attached picture. The present invention comprises driving roller 3, the first driven roller 1, the second driven roller 2, according to the belt-feeding direction of packing belt, the first driven roller 1 is in the downstream of the second driven roller 2;

[0015] Both the first driven roller 1 and the second driven roller 2 are installed eccentrically; the first driven roller 1 is driven by the spring 10 to always lean against the driving roller 3, and the second driven roller 2 leans against the driving roller 3 through the control of the cam 4. On the driving roller 3 and away from the driving roller 3. Reference numeral 30 is the driving motor of the driving roller.

[0016] The spring 10 can drive the first driven roller 1 to always lean against the driving roller 3 through the connection mechanism. For example, the shaft of the first driven roller 1 is connected to the spring 10 through a connecting rod 11 .

[0017] Between the first driven roller 1...

Abstract

The invention provides a belt feeding, withdrawing and tensioning device of a packer. The device comprises a driving roller, a first driven roller and a second driven roller. In the packing belt feeding direction, the first driven roller is positioned in the downstream of the second driven roller. The first driven roller and the second driven roller are both mounted eccentrically, the first driven roller is driven by a spring to constantly lean against the driving roller, and the second driven roller is controlled by a cam to lean against and be away from the driving roller. The device is capable of completing belt withdrawing and tensioning, and is simple in structure, lower in fault rate and good in packing effect. Besides, action of belt withdrawing along with belt tensioning can be achieved, and when a packing belt is tensioned in place, a control device can obtain signals accurately in real time by depending on current change of a motor, and other devices of the packer are accurately controlled to carry out subsequent steps of belt cutting, ironing and adhering and the like.

Description

technical field [0001] The invention relates to a feeding and unwinding belt and a tensioning belt device of a baler. Background technique [0002] The packing machine is a device for binding items with packing tape. The whole packing process has to go through the steps of feeding, unwinding, tightening, and hot sticking. In the past, the sending and unwinding belt and the tensioning belt were generally implemented by a pair of roller sets respectively. The roller set generally consisted of a driving roller and a driven wheel that can be attached to the driving roller and separated from the driving roller. The strength of the barrel is used to cooperate with the active roller gear to achieve tension. The structure is relatively complicated, and the frequency of work failures during packaging is high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a feeding and unwinding belt and a tensioning belt device of a ba...
