A kind of novel bar breaking apparatus
Technical field
The utility model relates to a kind of device that ribbon is broken.
Background technology
Traditional textile industry particularly look is spun the stock-dye preparatory process in field, and the segment that needs manually ribbon is torn into 10-15cm dyes again, and workload is large, and labour intensity is high, and efficient is low, and regularity is poor, affects dyeing quality and efficient.
Summary of the invention
The shortcoming that exists for solving existing artificial disconnected bar, the utility model provides a kind of conveniently bar breaking apparatus, and its technical scheme of taking is:
this device comprises frame, be fixed on the guide strip rack of frame right-hand member, be fixed on drawing rollers I and roller I on the frame leftward position by bearing, be fixed on drawing rollers II and roller II on the frame right positions by bearing, and evenly be fixed on a plurality of conducting bar rollers on guide strip rack by bearing, one end of drawing rollers I is fixed with belt wheel and gear I, the same end of drawing rollers II is fixed with the gear II, be fixed with carrier gear by bearing on the centre position of frame, the two ends, left and right of carrier gear are meshed with gear I and gear II respectively, the number of teeth of gear I is less than the number of teeth of gear II, roller I and roller II by each self-corresponding compression spring push up respectively be pressed in drawing rollers I and drawing rollers II above, the below of each conducting bar roller is provided with the bar cylinder corresponding with it, the lower left of drawing rollers I is provided with surge drum.
This device can be broken ribbon automatically, has simple in structure, high efficiency, the poor good characteristics of regularity.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
as shown in Figure 1, guide strip rack 12 is fixed on frame 1 right-hand member, drawing rollers I 2 and roller I 4 are fixed on frame 1 leftward position by bearing, drawing rollers II 3 and roller II 5 are fixed on the frame right positions by bearing, a plurality of conducting bar rollers 10 evenly are fixed on guide strip rack 12 by bearing, one end fixed pulley 6 and the gear I 7 of drawing rollers I 2, the same end of drawing rollers II 3 is fixed with gear II 9, on the centre position of frame 1 by the fixing carrier gear 8 of bearing, the two ends, left and right of carrier gear 8 are meshed with gear I 7 and gear II 9 respectively, the number of teeth of gear I 7 is less than the number of teeth of gear II 9, roller I 4 and roller II 5 by each self-corresponding compression spring 11 push up respectively be pressed in drawing rollers I 2 and drawing rollers II 3 above, the below of each conducting bar roller 10 is provided with the bar cylinder 13 corresponding with it, the lower left of drawing rollers I 2 is provided with surge drum 14.
Compression spring 11 is unclamped release, and drawing rollers I 2 and roller I 4 and drawing rollers II 3 and roller II 5 can be separated.After manually the ribbon in all cylinders 13 being collected, by conducting bar roller 10 guide to drawing rollers I 2 and drawing rollers II 3 above, with compression spring 11 pressurizations, roller I 4 and roller II 5 are pressed in ribbon on drawing rollers I 2 and drawing rollers II 3 with certain pressure respectively.Switch on power after start, motor drives drawing rollers I 2 by belt wheel 6 and rotates, and simultaneously by the transmission of gear I 7, carrier gear 8 and gear II 9, drives drawing rollers II 3 and rotates, roller I 4 and the passive rotation of roller II 5.The number of teeth that is less than gear II 9 due to the number of teeth of gear I 7, thereby make the linear velocity of drawing rollers I 2 greater than the linear velocity of drawing rollers II 3, utilize the linear differential of two drawing rollers that ribbon is broken, drawing rollers I 2 is transported to the ribbon of tear fracture in bar cylinder 14 simultaneously, collects completely and enters next process after cylinder.
