Referring to fig. 1, 2, 5 and 6, a flattened idler roller for a compounding machine, comprising: the device comprises a rotating shaft 1, two first propping parts 2, two groups of screw rods 3, a middle roller 4, two side rollers 5, two compression springs 6 and two limiting pieces 7.

Referring to fig. 3 and 7, the rotary shaft 1 includes: a middle portion 1a and two side portions 1b. The two side edge portions 1b are detachably and fixedly connected to both sides of the intermediate portion 1a, respectively.

The middle portion 1a has a larger cross section than the side portions 1 b. In this way, after the subsequent intermediate roll 4 is fixedly connected to the intermediate section 1a, there can be a set spacing between the roll body sections and the side sections 1b of the intermediate roll 4 beyond the intermediate section 1 a.

The two first supporting parts 2 are respectively connected to the two side edge parts 1b of the rotating shaft 1 in a sliding way along the axial direction. The two groups of screw rods 3 are arranged on the rotating shaft 1 and are respectively positioned in the cavities of the two side edge parts 1b, and the positions of the first propping parts 2 on the same side are adjusted.

Namely, the side edge part 1b is provided with a plurality of first through grooves 1b1 communicated with the cavity of the side edge part 1b, and the connecting part 2a of the first propping part 2 is positioned in the cavity of the side edge part 1b for connecting the screw rod 3; the plurality of propping portions 2b respectively penetrate out of the side edge portions 1b from the plurality of first through grooves 1b1 for being propped by the subsequent compression springs 6, and can also limit the rotation of the first propping portions 2 relative to the side edge portions 1 b.

Referring to fig. 2 and 3, alternatively, the first arrangement of the screw 3, the side portion 1b and the first supporting portion 2 may be: the first through groove 1b1 on the side portion 1b penetrates the side portion 1b near the end of the middle portion 1 a; the connecting part 2a and the plurality of propping parts 2b of the first propping part 2 are integrally arranged; two bearings matched with the screw rod 3 are arranged at the end part of the side edge part 1b away from the middle part 1a, and the other bearing is arranged at the middle part 1a.

Referring to fig. 6, 7 and 8, alternatively, the second arrangement of the screw 3, the side portion 1b and the first supporting portion 2 may be: two bearings matched with the screw rod 3 are respectively arranged at two ends of the side edge part 1 b; the plurality of supporting portions 2b of the first supporting portion 2 are detachably and fixedly connected to the connecting portion 2a.

The middle roller 4 is hollow and fixedly connected to the middle part 1a of the rotating shaft 1. Specifically, the intermediate roller 4 may be provided with a plurality of stepped first through holes, and fastened to the intermediate portion 1a by screw-threaded connection.

The two side rollers 5 are also hollow, with the same outer diameter as the intermediate roller 4. Both side rollers 5 are axially slidable with respect to the intermediate roller 4 and are located on both sides of the intermediate roller 4, respectively, i.e. both side rollers 5 and the intermediate roller 4 are rotatable together with the shaft 1.

Referring to fig. 1, 2 and 4, alternatively, the two side rollers 5 may be roller segments slidably connected to the middle roller 4 beyond the middle portion 1a, respectively. Specifically, a plurality of limit grooves 4a may be formed in the inner wall of the intermediate roller 4, and a first cylindrical portion 5c inserted into the intermediate roller 4 is integrally formed at one end of the side roller 5 near the intermediate roller 4, and a plurality of limit protruding strips 5c1 matching with the limit grooves 4a are formed in the first cylindrical portion 5 c.

Referring to fig. 5, 6 and 7, alternatively, two side rollers 5 may be slidably connected to the two side portions 1b, respectively. Specifically, the side edge portion 1b is provided with a connecting section 1b2 having a regular hexagonal outer wall, and the side edge roller 5 is sleeved on and slides in the connecting section 1b2.

Two compression springs 6 are respectively sleeved on two side edge portions 1b of the rotating shaft 1, one end of each compression spring is propped against the side edge roller 5 on the same side, and the other end of each compression spring is propped against the first propping part 2 on the same side.

Referring to fig. 2 and 6, alternatively, both side rollers 5 include: a roller body 5a and a third abutting portion 5b. The third supporting part 5b is detachably and fixedly connected in the roller body 5 a. Thus, by removing the second supporting portion 7b, the spring can be taken out more conveniently, and replacement and assembly are facilitated.

The two limit pieces 7 limit the two side rollers 5, respectively. In the limiting process, the limiting piece 7 enables the side roller 5 to overcome the compression spring 6 and keep a position close to the middle roller 4, and can directly prop against the middle roller 4. The two stoppers 7 can also release the stoppers by the first abutting portion 2.

Referring to fig. 2, alternatively, both of the limiting members 7 are magnets 7c, so that the side roller 5 is attracted to the middle roller 4. Specifically, the two side rollers 5 may employ "roller body sections slidably connected to the intermediate roller 4 beyond the intermediate portion 1a, respectively", and the magnet 7c is fitted on the first cylindrical portion 5 c.

In this way, the limiting piece 7 is made to limit, the fabric passes through the flattening guide roller, and the enveloping angle is formed on the flattening guide roller. The position of the first propping part 2 is adjusted through the screw rod 3, so that the first propping part 2 is close to the side roller 5, the force of the compression spring 6 on the side roller 5 is increased, the force absorbed by the magnet 7c is overcome, and the limit is released. After the limiting piece 7 releases the limiting, under the action of the compression spring 6, the side rollers 5 are far away from the middle roller 4, friction force is generated by two side rollers 5 on two side portions of the fabric, and accordingly, the side rollers 5 generate reverse reaction forces on the fabric, and the two reaction forces act on the two side portions of the fabric to straighten and flatten the fabric. That is, the side roller 5 is first far away from the middle roller 4, the acting force of the compression spring 6 on the side roller 5 is gradually reduced to be balanced with the friction force, and the side roller 5 is finally fixed relative to the middle roller 4.

Referring to fig. 6, alternatively, both the stoppers 7 include: a second cylindrical portion 7a and a second abutting portion 7b. The first end of the second cylindrical portion 7a is fixedly arranged at the end portion, close to the middle roller 4, of the side roller 5, and the second supporting portion 7b is fixedly arranged at the second end of the second cylindrical portion 7 a. At the time of limiting, the first supporting part 2 is positioned in the second cylindrical part 7a and supports the second supporting part 7b.

In this way, the limiting piece 7 is made to limit, the fabric passes through the flattening guide roller, and the enveloping angle is formed on the flattening guide roller. The first supporting part 2 is far away from the second supporting part 7b by adjusting the position of the first supporting part 2 through the screw rod 3, and the limit is released.

Correspondingly, the screw 3, the side portion 1b and the first abutment 2 are preferably arranged in a second configuration. Compared with the first setting, the disassembly and assembly are more convenient under the second setting.
