Description

Technical Field

[0001] The utility model relates to the technical field of combing machines, in particular to an automatic spinning-in fan for combing machines. Background Art

[0002] At the beginning of the new combing process, the three sets of fans equipped with the combing machine's automatic spinning fans were 7.5kw fans. During production, it was found that the fans had excess negative pressure, and after negotiation with the manufacturer, they were replaced with 5.5kw fans. The negative pressure during production can well meet the requirements of the combing machine's automatic spinning.

[0003] However, during use, the automatic spinning fan sucked in 28 pre-combined cotton strips to form a cotton roll. When the cotton roll was automatically spinning, the cotton roll head was sucked in and entered the fan in a lump. The fan impeller often got stuck, and in serious cases, a fire alarm occurred. During the production process, when the cotton roll head was sucked in, there was a sound of hitting between the impeller and the air inlet volute. It was initially determined that the distance between the impeller and the volute was too small, causing the impeller to get stuck and the fire alarm to occur. Therefore, it is urgent to solve this problem.

[0004] The above contents are only used to assist in understanding the technical solution of the present utility model, and do not constitute an admission that the above contents are the closest prior art. Utility Model Content

[0021] Example

[0022] See also Figure 1 As shown:

[0023] The utility model provides an automatic spinning-in fan for a combing machine, comprising a fan 10, an ear tube 32 and a negative pressure regulating component.

[0024] In actual use, the fan 10 is installed on the combing machine, one end of the ear-stirring tube 32 is opposite to the fan blade 11 of the fan 10, and is connected to the negative pressure regulating component. The negative pressure regulating component is installed at the air inlet 12 of the fan 10 and can move in the horizontal direction of the air inlet 12. By adjusting the distance between the ear-stirring tube 32 and the fan blade 11 of the fan 10, the influence of the negative pressure generated by the fan 10 on the cotton roll head is reduced, and the cotton roll head is prevented from being sucked into the ear-stirring tube 32 to cause safety hazards. The whole adjustment process is simple, efficient, and easy to use.

[0025] The negative pressure regulating assembly is mainly composed of a cylinder 31, a regulating part and a sealing part.

[0026] The auditory tube 32 is connected to the through hole at the center of the cylinder 31; the cylinder 31 and the air inlet 12 form a nested connection; one end of the adjustment part is connected to the side wall of the cylinder 31, and the other end is connected to the outer shell at the air inlet 12 of the fan 10; the sealing part is arranged along the circumferential direction of the cylinder 31, and is used to seal the gap between the cylinder 31 and the air inlet 12.

[0027] By providing the adjustment part and the sealing part, the distance between the ear tube 32 and the blades 11 of the fan 10 can be adjusted without affecting the formation of negative pressure inside the fan 10, thereby ensuring the use effect of the fan 10 after adjustment.

[0028] The adjusting part is mainly composed of a connecting iron sheet 21, a connecting threaded rod 22, a connecting nut 23 and an adjusting sleeve.

[0029] One end of the connecting iron sheet 21 is vertically connected to the side wall of the cylinder 31; one end of the connecting threaded rod 22 is vertically connected to the outer shell at the air inlet 12 of the fan 10, and the other end is plugged into the connecting hole on the connecting iron sheet 21; the adjusting sleeve is sleeved on the connecting threaded rod 22, one end of the adjusting sleeve is abutted against the outer shell at the air inlet 12 of the fan 10, and the other end is abutted against the connecting iron sheet 21, and the adjusting sleeve has at least three models with different lengths; the connecting nut 23 is threadedly connected to the end of the connecting threaded rod 22.

[0030] During actual use, the operator selects an adjustment sleeve of a corresponding model according to the negative pressure generated by the fan 10, so that the distance between the ear tube 32 and the fan blades 11 of the fan 10 is adjusted to the optimal distance, thereby preventing the cotton roll head from being sucked into the ear tube 32 and contacting the fan blades 11, thereby improving production safety.

[0031] The sealing part includes a corrugated rubber tube 33 or an elastic expansion tube. The corrugated rubber tube 33 is sleeved on the outer wall of the cylinder 31, and one end of the corrugated rubber tube 33 is connected to the housing at the air inlet 12 of the fan 10, and the other end is connected to the outer wall of the cylinder 31. Since the corrugated rubber tube 33 can be expanded and contracted along the length direction,

[0032] The connection between the corrugated rubber tube 33 and the outer wall of the cylinder 31 is coated with sealant, thereby improving the sealing effect of the corrugated rubber tube 33 and reducing the influence of the distance adjustment between the fan 10 and the auditory tube 32 on the sealing.

[0033] An annular pressing ring is provided at the connection between the corrugated rubber tube 33 and the outer shell at the air inlet 12 of the fan 10, and the annular pressing ring is connected to the outer shell at the air inlet 12 of the fan 10; an outer flange is provided at the end where the corrugated rubber tube 33 is connected to the outer shell of the fan 10, and the outer flange is located between the outer shell and the annular pressing ring. Through such a setting, the sealing effect between the corrugated rubber tube 33 and the outer shell of the fan 10 is ensured. In addition, in actual use, sealant can also be applied between the corrugated rubber tube 33 and the outer shell of the fan 10 to ensure a tighter seal.

[0034] In actual use, at least 6 connecting iron sheets 21 are arranged and evenly spaced along the circumferential direction of the cylinder 31. With such an arrangement, the connection between the cylinder 31 and the housing of the fan 10 is more stable, and the cylinder 31 will not shake or make abnormal noise after the fan 10 is started, and the auditory tube 32 is better supported.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
