AI Technical Summary
The existing dust removal fans for textiles have low fan speeds, resulting in low air pressure. This makes it difficult to remove fallen cotton in a timely manner, which can easily cause blockages and equipment failures, affecting production.
By increasing the diameter of the reducer's drive pulley to 145mm-155mm, the rotational speed of the fan's driven pulley is increased, thereby improving the fan's air pressure and suction, and ensuring stable operation.
Increase the suction power of the fan to prevent cotton from clogging the equipment, reduce the failure rate of the equipment, and improve production efficiency.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a dust removal fan technical field especially is related to a strong effect carding dust removal fan for weaving. BACKGROUND
[0002] The strong effect carding dust removal fan for weaving comprises a motor, a speed reducer and a fan, the motor drives the speed reducer, the speed reducer has a driving pulley, the driving pulley of the speed reducer drives the passive pulley of the fan to rotate, and the negative pressure generated by the fan is used to suck the noil in the dust filtering chamber.
[0003] At present, the diameter of the driving pulley of the speed reducer of the carding dust removal fan for weaving is smaller (mostly φ95mm) than that of the passive pulley of the fan, which leads to the slow rotation speed of the passive pulley of the fan driven by the driving pulley, and the low rotation speed of the fan leads to the small air pressure generated by the fan, so that the noil in the primary filter of the fan cannot be sucked in time, which easily causes blockage and shutdown, and not only affects normal production, but also increases the failure rate and damage rate of the equipment. SUMMARY
[0004] The utility model solves the technical problems that: provide a strong effect carding dust removal fan for weaving to solve the problems raised in the background art.
[0005] The utility model adopts the technical scheme that: a strong effect carding dust removal fan for weaving, including motor, speed reducer and fan, motor drives speed reducer, speed reducer has driving pulley, driving pulley of speed reducer drives passive pulley of fan to rotate, the diameter of the driving pulley of the speed reducer is 145mm~155mm, and the diameter of the passive pulley of the fan is 425mm.
[0006] Further, the diameter of the driving pulley of the speed reducer is 150mm.
[0007] The strong effect carding dust removal fan for weaving can properly improve the air pressure of the fan, increase the suction force, make the noil in the primary filter of the fan be sucked in time, achieve good carding and dust removal effect, avoid the shutdown caused by blockage, reduce the failure rate and damage rate of the equipment, and improve the production efficiency. BRIEF DESCRIPTION OF DRAWINGS
[0008] The utility model will be further described below in connection with the drawings and examples.
[0009] Figure 1 It is the structural schematic diagram of the utility model.
[0010] In the diagram: 1. Motor; 2. Reducer; 2-1. Drive pulley; 3. Fan; 3-1. Driven pulley. Detailed Implementation
[0011] A high-efficiency dust removal fan for textiles, such as Figure 1 As shown, it includes a motor 1, a reducer 2, and a fan 3. The motor 1 drives the reducer 2. The reducer 3 has a drive pulley 2-1. The drive pulley 2-1 of the reducer 3 drives the driven pulley 3-1 of the fan 3 to rotate. The diameter of the drive pulley 2-1 of the reducer 2 is 145mm to 155mm, and the diameter of the driven pulley 3-1 of the fan 3 is 425mm.
[0012] In this example, the diameter of the drive pulley 2-1 of the reducer 2 is 150mm.
[0013] Without changing the rated speed of the motor and the diameter of the driven pulley of the fan, the speed of the driven pulley of the fan can be increased by replacing it with a drive pulley of the reducer with one of larger diameter. This increases the speed of the fan, the wind pressure generated by the fan, and its suction force. However, when replacing the drive pulley of the reducer with one of larger diameter, the operational stability, safety, and reliability of the reducer and the fan must also be considered. Furthermore, the suction force of the fan is not necessarily better the greater it is; a reasonable and appropriate suction force is required.
[0014] Calculations and tests have shown that, for a 425mm diameter passive pulley for the fan, the optimal diameter for the reducer's active pulley is between 145mm and 155mm. Within this range, the diameter of the reducer's active pulley ensures stable and reliable operation of both the reducer and the fan, while also appropriately increasing the fan's air pressure and suction. This allows the lint in the fan's primary filter to be promptly removed, achieving a good dust removal effect.
[0015] The above embodiments are only used to explain the present utility model and are not intended to limit the protection of the present utility model. Any non-substantial modifications made based on the essential solution of the present utility model shall fall within the protection scope of the present utility model.
