Abstract
The utility model provides a two-way multi-roll drafting machine for a strap production line. The two-way multi-roll drafting machine comprises a box body, drafting rollers, drafting main shafts, and an input shaft parallel to the movement direction of the production line, wherein a plurality of drafting rollers are staggered vertically and are arranged on both lateral surfaces of the box body in a mirror symmetry manner; the two symmetrical drafting rollers are connected through one drafting main shaft; the input shaft is arranged on the rear of the box body; one end of the input shaft is arranged in the middle of the box body, and the other end of the input shaft is extended outwards and is connected with a driving source; a worm gear is arranged in the input shaft; the input shaft is driven by the worm gear and is rotated with the adjacent drafting main shaft together; and the drafting main shaft transmits power to other drafting main shafts through gears with the same number of teeth. Because a two-way synchronization drafting mode is adopted by the two-way multi-roll drafting machine, both ends of the two-way multi-roll drafting machine are uniformly stressed, deep groove ball bearings on the drafting rollers are uniformly stressed, the failure rate of equipment is reduced greatly, and a simple and practical design reduces a large number of occupied areas of the equipment.
Description
Technical field
The utility model relates to the technical field that the strap streamline is produced, and refers in particular to a kind of two-way multiple roll drawing machine that is used on the strap production line.
Background technology
Existing domestic and international strap manufacturer all adopts one-way drawing at the multiple roll drawing machine that uses.Existing many traditional strap automatic assembly line drawing-off production equipments; The difference of two the draft apparatus linear velocities strap that stretches before and after production process need be utilized; In order to make strap reach maximum fracture strength, must increase the linear differential of two draft apparatus as far as possible.Because the most of regenerative raw materials that uses of strap, raw material impurity is more, abnormal conditions such as broken belt under the requirement of the certain fracture strength of strap, occur through regular meeting.If when 4 and above strap appear producing simultaneously on the drawing roller in one-way drawing,, occur easily disturbing causing chain reaction, simultaneously 4 strap broken belts when a certain strap broken belt wherein.If when the one-way drawing roller surpassed 3 straps, workman's danger when drawstring is started again was increased sharply, and occurs scratch tape easily and snarls the potential safety hazard that operative employee's arm causes industrial injury.Therefore most of strap manufacturer is in order to improve yield rate, and the fracture strength that is merely able to as far as possible to reduce strap reduces the probability of broken belt.But the low fracture strength strap that can cause whole industry competitively to produce like this to fail, part strap producer also selects to conceal the fact that strap is low fracture strength, pretends to be the high strength packing sale of taking.The easy like this underlying rule that causes the strap industry, the fracture strength index of the strap of every family strap manufacturer production all is lower than the index of declaring.Replace the strap of passing.Rule of thumb, single drawing roller is suitable at 3 strap, not only keeps output but also prevent the broken belt chain reaction.If continue to use the one-way drawing roller, the trend that has been merely able to limit the maximization of production line, therefore, two-way drawing roller has just had the demand in market.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, provide a kind of simple in structure, production cost is low, high efficiency be used for the two-way multiple roll drawing machine on the strap production line.
For realizing above-mentioned purpose; The technical scheme that the utility model provided is: a kind of two-way multiple roll drawing machine that is used on the strap production line; It includes casing, drawing-off roller, drawing-off main shaft and a power shaft parallel with the direction of motion of production line, and wherein, described drawing-off roller is many staggered up and down arranging; And mirror image is installed on the two sides of casing symmetrically, and is connected through a drawing-off main shaft between two drawing-off rollers of symmetry; Power shaft places the back of casing; The one of which end is installed in the middle part in the casing; Its other end is protruding to be connected with drive source; And be built-in with worm and gear at power shaft, drive a drawing-off main axis rotation adjacent thereto, and this drawing-off main shaft passes through the identical gear transmission power of the number of teeth with other drawing-off main shaft through this worm and gear.
Described drive source is motor or reductor.
Described gear is a helical gear.
The utility model is after having adopted such scheme; Owing to adopt the bi-directional synchronization drawing-off, make that the two ends of the utility model are stressed evenly, the deep groove ball bearing on the drawing-off roller is stressed evenly; Can reduce equipment failure rate significantly; The design of brief practicality has reduced a large amount of occupation of land space of equipment, is applicable to the beol equipment of high-strength plastic steel band.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with specific embodiment the utility model is described further.
Shown in accompanying drawing 1; Present embodiment is the two-way seven roller drawing machines that are used on the strap production line; It includes casing 1, drawing-off roller 2, drawing-off main shaft and a power shaft parallel with the direction of motion of production line 3, and wherein, described drawing-off roller 2 is 14 staggered up and down arranging; And mirror image is installed on the two sides of casing 1 symmetrically, and is connected through a drawing-off main shaft between two drawing-off rollers 2 of symmetry; Power shaft 3 places the back of casing 1; The one of which end is installed in the middle part in the casing 1, and its other end is protruding to be connected with drive source (motor or reductor), and is built-in with worm and gear at power shaft 3; Drive a drawing-off main axis rotation adjacent thereto through this worm and gear; And this drawing-off main shaft and other drawing-off main shaft be through the identical helical gear transferring power of the number of teeth, makes that the gearratio of all drawing-off rollers 2 of present embodiment is 1:1, is applicable to the draw conditions of high strength strap.In addition, the utility model can be according to different draw ratio requirements, the drive source of external different speed reducing ratio.In a word, because the drawing-off of the utility model bi-directional synchronization makes its two ends stressed evenly, the deep groove ball bearing on the drawing-off roller 2 is stressed evenly to reduce equipment failure rate significantly, is applicable to the beol equipment of high strength strap.Two-way drawing roller efficiently solves the difficult problem that local broken belt causes chain broken belt.Two-way drawing roller can rise to 6 by 3 with the packing tape number that strap production line single line is produced simultaneously, has significantly improved the single line output of strap production line, meets the development trend of maximization of strap production line and high speed, is worthy to be popularized.
The embodiment of the above is the preferred embodiment of the utility model only, is not the practical range that limits the utility model with this, so the variation that all shapes according to the utility model, principle are done all should be encompassed in the protection domain of the utility model.
