Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, the roller assembly structure with the V-shaped opening comprises a first roller 1 and a second roller 2, wherein the first roller 1 and the second roller 2 are arranged in parallel and opposite to each other, the end parts of the first roller 1 and the second roller 2 are respectively provided with an anti-rolling cover 3, and the end surfaces of the anti-rolling covers 3 are respectively provided with a roller protection sheet 14.

Referring to fig. 2, the first and

second rollers

1 and 2 each include a roller belt 11, a driving rod 12, and a driven rod 13, the driven rod 13 and the driving rod 12 are arranged in parallel up and down, and the anti-rolling covers 3 are respectively arranged between the ends of the driving rod 12 and the driven rod 13, the roller belt 11 is tensioned on the driving rod 12 and the driven rod 13, and the driving rod 12 and the driven rod 13 are obliquely provided with a plurality of roller support bars 15, the roller support bars 15 are connected by a shaft connection manner, so that the roller support bars 15 between the first and

second rollers

1 and 2 form a cone shape, in this embodiment, the roller support bars are designed in multiple sections, thereby improving the linear strength of the first and

second rollers

1 and 2, and simultaneously avoiding the deformation caused by the excessive length of the roller support bars 15, the machine tool is provided with a pair of brackets, so that the driving rods 12 of the first and

second rollers

1 and 2 are respectively rotatably arranged between the brackets, a driving device is fixedly installed on one bracket, a motor is preferably adopted in the embodiment, a gear transmission mode is preferably adopted between the first roller 1 and the second roller 2 and the driving device, so that the driving device drives the roller belts 11 on the first roller 1 and the second roller 2 to move relatively and pull the fabric downwards, and the roller guard plates at the end parts of the first roller and the second roller are designed without teeth in the embodiment, so that yarn can be prevented from being clamped on the roller guard plates.

Referring to fig. 1 and 3, the end of the driven rod 13 is in a tapered structure, the end of the roller belt 11 is stepped, so that the roller belt 11 is tensioned between the driving rod 12 and the driven rod 13, the end of the roller belt 11 gradually decreases along with the end of the driven rod 13, so that a V-shaped gap is formed between the ends of the first and

second rollers

1 and 2, the ends of the first and

second roller belts

1 and 2 are also in a tapered structure to be installed in a matching manner, and the yarn can be transitionally drawn between the first and

second roller belts

1 and 2 through a V-shaped included angle, the ends of the first and

second rollers

1 and 2 are respectively and fixedly provided with an anti-rolling cover 3, a roller guard 14 is covered on the anti-rolling cover 3 to prevent the yarn from rolling into the driving rod or the driven rod, the size of the anti-rolling cover 3 is smaller than the main body size of the first and

second roller belts

1 and 2 to ensure that a gap 31 exists between the anti-rolling cover 3 and prevent the yarn from rolling into the first and the driven rod 12, The

second roller belt

1, 2 roll the process and pull the tension, lead to the yarn to be torn, or the yarn presss from both sides tightly for a long time and leads to it to be rolled up and press from both sides, or avoid leading to the yarn to be ground off because of the undersize of first, second roller tip, the aircraft nose sends the yarn into the faller to weave when the yarn needs to use, and draw the fabric through first,

second roller

1, 2 and descend, when the yarn need not use, the aircraft nose sends the yarn to in preventing the clearance 31 between the roll cover 3, make the yarn stop in the clearance 31 and do not receive the first,

second roller

1, 2's traction, prevent effectively that the yarn end of a thread from being drawn into in first roller 1 or second roller 2, thereby avoid appearing the circumstances of card line, reduce the waste of yarn.

Referring to fig. 4, the end face of the roller guard 14 has a through hole 141, the end face of the roll screen 3 has a strip hole 32, the roller guard is fixedly connected with the roll screen 3 by passing a screw through the through hole and the strip hole 32, and the distance between the roll screen 3 and the first and
