Abstract

The utility model discloses a cleaning component for a draft device for a roving frame to solve the problem that the cleaning component for the draft device of the roving frame has large transmission resistance and is easily damaged. The cleaning component comprises a driving rotary roller and a driven rotary roller which are in belt transmission connection, and a cleaning belt; and after improvement, the driving rotary roller is a serrated roller, the cleaning belt is a toothed belt matched with the driving rotary roller, and the outer surface of the cleaning belt is provided with a napping layer. The cleaning component has the advantages that 1, the driving rotary roller drives the cleaning belt, namely the toothed belt reliably, and slip is avoided; 2, the outer surface of the toothed belt is subjected to napping treatment, dust and lower piles on the rollers can be effectively cleaned or brought away, and the service life of the cleaning component is prolonged; and 3, the driven rotary roller has an inner shaft, outer sleeve and a middle bearing structure, so that the resistance to motion is reduced and the rotary flexibility is greatly improved. By the improvement, a defect that foreign matters are brought into yarns due to inflexible rotation is overcome, the working reliability is obviously improved and the service life is obviously prolonged.

Description

A kind of bobbiner drafting assembly cleaning assemblies

Technical field

The utility model relates to a kind of textile machine parts, especially for the cleaning assemblies of bobbiner drafting assembly, belongs to the Weaving device technical field.

Background technology

Bobbiner drafting assembly needs often cleaning top roller, to prevent bringing the fault that sliver forms into because of flyings gather in running.The cleaning assemblies of bobbiner drafting assembly commonly used is made up of a cover tape handler; Its active revolving roll is wooden roller; Its outer surface is surrounded by the layer of metal peronium to increase frictional force, and driven voller is a solid shafting, and initiatively revolving roll intermittently drives the cleaning band motion of being done by white Buddhist nun's flannelette; Cleaning band in motion process with the top roller CONTACT WITH FRICTION, thereby the cleaning top roller.Find that in use the problem that this cleaning assemblies exists is following: turn round dumb, the transmission resistance is big, cleaning band is prone to make because of skidding and cleans the inefficacy flyings and bring yarn into; Initiatively the peronium of revolving roll damages easily; Cleaning band is prone to take place burr to be damaged, and causes flyings to gather.The problems referred to above cause the cleaning assemblies fault that takes place frequently, and cause the increase of maintenance use cost on the one hand, have influence on equipment work efficient and product quality on the other hand.

The utility model content

The utility model is used to overcome the defective of prior art and a kind of ensuring smooth transmission, non-damageable bobbiner drafting assembly cleaning assemblies is provided.

The alleged problem of the utility model is that following technical scheme solves:

A kind of bobbiner drafting assembly cleaning assemblies; Constitute the active revolving roll, driven revolving roll and the cleaning band that comprise that band is in transmission connection; Its special feature is: said active revolving roll is a serrated roller, and said cleaning band is and the cog belt of active revolving roll profile of tooth coupling that the cleaning band outer surface is the plucking layer.

Above-mentioned bobbiner drafting assembly cleaning assemblies, said driven revolving roll is made up of axle, needle bearing and sleeve, said needle bearing between axle and sleeve, needle bearing respectively with axle, sleeve interference fit.

The utility model improves to big, the flimsy problem of bobbiner drafting assembly cleaning assemblies transmission resistance, and its characteristics are following: 1. initiatively revolving roll and cleaning band adopt the cog belt transmission, make its reliable transmission, avoid skidding; 2. carry out plucking at the extexine of cog belt and handle, can clean effectively or glue top roller trifle in the world and short flannel, and improved cleaning band service life; 3. the structure of axle, overcoat, intermediate bearing reduced the resistance of motion in driven revolving roll adopted, and the revolution flexibility improves greatly.Above-mentioned improvement has overcome because of turning round the ineffective drawback that causes flyings to bring yarn into the utility model, and functional reliability and service life all are significantly increased.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is Figure 1B portion partial enlarged view;

Fig. 3 is Figure 1A-A cutaway view (amplification).

Label is represented as follows in the accompanying drawing: 1. revolving roll initiatively, 2. cleaning band, 2-1. plucking layer, 3. driven revolving roll, 3-1. sleeve, 3-2. needle bearing, 3-3. axle, 4. top roller.

The specific embodiment

Referring to Fig. 1, Fig. 2, the utility model constitutes active revolving roll 1, driven revolving roll 3 and the cleaning band 2 that comprises that band is in transmission connection.Be prone to the problem of skidding for solving the band transmission, initiatively revolving roll 1 adopts serrated roller, is uniformly distributed with rectangular teeth at the outer surface of roller; The cog belt that cleaning band 2 is and active revolving roll profile of tooth is mated, the cleaning band outer surface is treated to plucking layer 2-1 through plucking, and in the cleaning band motion process, the plucking layer contacts with top roller 4, cleans or glue the trifle in the world and the short flannel at top roller 4 places.

Referring to Fig. 1, Fig. 3, make ensuring smooth transmission for reducing the resistance of motion, the driven revolving roll 3 of the utility model is made up of axle 3-3, needle bearing 3-2 and sleeve 3-1, needle bearing between axle and sleeve, needle bearing respectively with axle, sleeve interference fit.Cleaning band is sleeved on outside the driven revolving roll, relies on the tension band moving sleeve of cleaning band to rotate, owing to form rolling revolving through needle bearing 3-2 between sleeve 3-1 and the axle 3-3, frictional resistance is very little, can not produce the phenomenon that cleaning band skids.

Claims

1. bobbiner drafting assembly cleaning assemblies; Constitute the active revolving roll, driven revolving roll and the cleaning band that comprise that band is in transmission connection; It is characterized in that: said active revolving roll (1) is a serrated roller; Said cleaning band (2) is and the cog belt of active revolving roll profile of tooth coupling that the cleaning band outer surface is plucking layer (2-1).

2. bobbiner drafting assembly cleaning assemblies according to claim 1; It is characterized in that: said driven revolving roll (3) is made up of axle (3-3), needle bearing (3-2) and sleeve (3-1); Said needle bearing between axle and sleeve, needle bearing respectively with axle, sleeve interference fit.
