Description
Technical field
The utility model relates to a kind of drawing machine, relates in particular to a kind of web drawing machine.
Background technology
Generally adopt at present the upper and lower drawing roller of combination in pairs that web is carried out combing and drawing-off in the web production technology, with strengthen web laterally with toughness longitudinally.
The Chinese patent publication number is CN101270514A, the patent of invention that open day is on September 24th, 2008 discloses the combing drafting method in a kind of cotton and the chemical fibre fore-spinning technique, wherein come out with and a kind ofly adopted many drawing roller to the band saw tooth feeding the device that cotton layer carries out comb and parallel cotton fibers prior to spinning and drawing-off, per two counter extensioin rollers are formed a combing drafting unit in this device, the rotating speed difference of two counter extensioin rollers, wherein each drawing roller is initiatively drawing roller, sawtooth on each drawing roller carries out drafting of sliver when sliver is carried out combing, reach by the rotating speed of regulating every counter extensioin roller cotton layer is carried out combing simultaneously, removal of impurities and drawing-off; Though this device can be finished comb and parallel cotton fibers prior to spinning and drafting drawing-off simultaneously, improved production efficiency, but because it adopts many drawing roller to the band saw tooth to carry out drawing-off to feeding cotton layer, on preventing, sawtooth on the following drawing roller touches mutually and causes, following drawing roller can't be moved, so last, reserve certain clearance between the following drawing roller, thereby prevent, following drawing roller is touched mutually, but it is because last, there is certain clearance between the following drawing roller, cause, sawtooth on the following drawing roller can only extend into cotton and chemical fibre on, following top layer, and can't carry out the combing drawing-off, thereby cause the toughness of cotton and chemical fibre relatively poor to the intermediate layer of cotton and chemical fibre.
Summary of the invention
Technical problem to be solved in the utility model provides the stronger web drawing machine of a kind of web toughness.
For realizing above purpose, the technical scheme that the utility model adopted is: a kind of web drawing machine, include cotton device, drafting system successively and go out cotton device, describedly go into cotton device and comprise level, first driving wheel and first driven pulley that are provided with at interval, be socketed with first conveyer belt on described first driving wheel and described first driven pulley; Describedly go out cotton device and comprise level, second driving wheel and second driven pulley that the interval is provided with, be socketed with second conveyer belt on described second driving wheel and described second driven pulley, described second conveyer belt is provided with pinch roller, described pinch roller contacts with described second conveyer belt, it is characterized in that: described drafting system comprises lengthwise type frame and is arranged at least one drafting unit on the lengthwise type frame, described drafting unit comprises drawing-off rod and level, be disposed on first time drawing-off rod and second time drawing-off rod on the frame, the described drawing-off rod of going up is above between first time drawing-off rod and the second time drawing-off rod and contact with first time drawing-off rod and second time drawing-off rod respectively, the surface of described first time drawing-off rod and second time drawing-off rod is provided with the aciculiform projection, the end of this aciculiform projection is bent to form kink clockwise, and the angle of this kink and aciculiform projection is 80 to 100 degree.
The angle of described kink and aciculiform projection is 90 degree.
Described drafting unit is 4, and is horizontally placed on successively on the described lengthwise type frame.
Described first time drawing-off rod is connected with drive of motor by driving member with described second time drawing-off rod.
Described driving member is driving belt or chain.
Compared with prior art, the beneficial effects of the utility model are:
1. because the first time drawing-off rod of a kind of web drawing machine of the present utility model and the surface of second time drawing-off rod are provided with the aciculiform projection, the terminal instantaneous pin of this aciculiform projection is bent to form kink, the angle of this kink and aciculiform projection is 80 to 100 degree, last drawing-off rod contacts with first time drawing-off rod and second time drawing-off rod respectively, because last drawing-off rod and first time drawing-off rod, there is not the gap between second time drawing-off rod, therefore the kink of projection can pass web on the web, drawing-off is carried out in following top layer and intermediate layer, and therefore web toughness of the present utility model is stronger.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of first time drawing-off rod in the utility model.
Among the figure: go into cotton device 4, drafting system 6 goes out cotton device 8, first driving wheel, 10, the first driven pulleys, 12, the first conveyer belts 14, second driving wheel, 16, the second driven pulleys, 18, the second conveyer belts 20, pinch roller 22, frame 24, drafting unit 26,28, the second times drawing-off rods 30 of first time drawing-off rod, last drawing-off rod 32, projection 34, kink 36.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
Referring to shown in Figure 1, a kind of web drawing machine includes cotton device 4, drafting system 6 successively and goes out cotton device 8.
Go into cotton device 4 and comprise horizontally disposed first driving wheel 10, first driven pulley 12, socket one first conveyer belt 14 on first driving wheel 10 and first driven pulley 12.
