According to one embodiment of the present disclosure, a strip material retaining mechanism is provided. The banded material retaining mechanism includes a housing 1, a transport assembly 2 and an air extraction assembly 3. A cavity 11 is formed inside the housing 1. The housing 1 has an open end 12 communicating with the cavity 11. The conveyor assembly 2 is disposed within the cavity 11 and exposed at the open end 12. The conveyor assembly 2 is used for conveying a strip-shaped material. The conveyor assembly 2 comprises a driving pulley 21, a driven pulley 22 and a plurality of belts 23. The plurality of belts 23 are sleeved outside the driving wheel 21 and the driven wheel 22 at intervals. And gaps are formed between the adjacent belts. In an operating state, a portion of the band-shaped material is opposite to the gap. Another portion of the strip-like material is adsorbed on at least one belt forming the gap. The air extraction assembly 3 comprises an air extraction tube 31. The exhaust pipe 31 is communicated with the cavity 11. The air extracting component 3 is used for extracting air from the cavity 11, so that the strip-shaped material is adsorbed on the conveying component 2.

As shown in fig. 1 to 6, the material of the case 1 is metal, plastic, inorganic material, or the like. The chamber 11 is a semi-enclosed structure. One side of the housing 1 is provided with an open end 12. The open end 12 communicates with the cavity 11. The shape of the open end 12 is circular, rectangular, oval, etc. The transport assembly 2 is disposed within the cavity 11 with the transport assembly 2 exposed at the open end 12. An air extraction assembly 3 is connected to one side of the housing 1. The air exhaust component 3 is communicated with the cavity 11.

The belt 23 is sleeved outside the driving wheel 21 and the driven wheel 22, and the belt 23 moves to drive the driven wheel 22 to rotate. The driving pulley 21 and the driven pulley 22 jointly tension the belt.

When the air exhaust component 3 is started, negative pressure is formed inside the cavity 11 relative to the outside of the cavity 11. As the ribbon material passes through the open end 12 of the housing 1, the ribbon material is attracted to the open end 12. The belt 23 is disposed at the open end 12 of the housing 1 such that the strip material is attracted to the belt 23.

As shown in fig. 2, the plurality of belts 23 are disposed at intervals. A gap is formed between the adjacent two belts 23. Negative pressure is formed at the gap. When the belt-like material is conveyed to the open end, a part of the belt-like material in the width direction may be opposed to the gap between the adjacent two belts 23, and the other part may be adsorbed on one of the belts 23.

Alternatively, the portions of the strip-shaped material in the width direction near the two edges may be respectively adsorbed on the two adjacent belts 23, and the portion near the middle may be opposed to the gap between the two belts 23 and completely cover the gap.

Air in the cavity 11 is sucked by the air suction assembly 3, so that the air pressure in the cavity 11 is smaller than the air pressure outside the cavity 11, and a pressure difference is formed. When the belt-shaped material is conveyed to the outer side of the opening end 12 of the shell 1, the belt-shaped material is adsorbed through the opening end 12, so that the belt-shaped material is attached to the conveying component 2 at the opening end 12, and the amplitude and force of the belt-shaped material in a free state in a swinging manner are reduced. Meanwhile, the conveying assembly 2 conveys the strip-shaped materials to move in the conveying direction, so that the problems of large-amplitude deviation and the like of the strip-shaped materials in the conveying process are avoided.

The first motor 25 is activated to rotate the driving pulley 21, thereby moving the belt 23 and the driven pulley 22. The plurality of belts 23 form a plurality of gaps at the open end 12. The gas is sucked away through the gap by the pumping assembly 3.

The number of the strip-shaped materials is consistent with the number of the gaps, the width of the gaps is larger than the width of the gaps, each gap corresponds to one strip-shaped material, and the edge of each strip-shaped material is attached to the edge of the adjacent belt 23. Alternatively, the width of the band-shaped material is greater than the width of the plurality of belts or the plurality of gaps. The plurality of belts 23 and the plurality of gaps convey a strip-shaped material together, and the edge of each strip-shaped material is attached to the edge of the belt 23 close to the edge.

In one example, the portion of the belt 23 straightened by the driving pulley 21 and the driven pulley 22 is used to convey a strip-like material.

As shown in fig. 2 to 6, when the pumping assembly 3 is started, a negative pressure is formed inside the cavity 11 relative to the outside of the cavity 11. The straightened part of the belt 23 can ensure that the belt-shaped material is conveyed straightly, and the position deviation of the belt-shaped material in the moving process is reduced, so that the belt-shaped material can more accurately reach the next process.

When the belt-shaped material is conveyed to the belt 23, the belt-shaped material is adsorbed through the airflow holes, so that the belt-shaped material is attached to the belt 23, and the amplitude and force of the belt-shaped material in a free state are reduced. Thereby leading the air exhaust component 3 to better adsorb the belt-shaped materials through the through holes 231 on the belt 23.
