Abstract
The invention provides a double-way multi-roller drafting machine for a packaging belt production line. The double-way multi-roller drafting machine for the packaging belt production line comprises a box body, drafting rollers, drafting main shafts and an input shaft, wherein the input shaft is parallel to the motion direction of the production line; the drafting rollers are arranged interlacedly up and down and are arranged on two sides of the box body in a mirror symmetry mode; two symmetrical drafting rollers are connected by one drafting main shaft; the input shaft is placed behind the box body; one end of the input shaft is arranged at the middle position in the box body and the other end of the input shaft extends outwards to be connected with a driving source; a worm gear is placed in the input shaft and drives the drafting main shaft adjacent to the input shaft to rotate; and power is transmitted between the drafting main shaft and other drafting main shafts through gears with the same number of teeth. In the invention, double-way synchronous drafting is adopted, so that force is uniformly applied to two ends of the double-way multi-roller drafting machine, force is uniformly applied to deep groove ball bearings on the drafting rollers and equipment failure rate can be greatly reduced. By adoption of simple and practicable design, large occupied area of the equipment is reduced.
Description
Technical field
The present invention relates to the technical field that the strap streamline is produced, refer 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 objective of the invention 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; Technical scheme provided by the present invention 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 present invention is after having adopted such scheme; Owing to adopt the bi-directional synchronization drawing-off, make two ends of the present invention 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 a structural representation of the present invention.
The specific embodiment
Below in conjunction with specific embodiment the present invention 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 present invention can be according to different draw ratio requirements, the drive source of external different speed reducing ratio.In a word, because bi-directional synchronization drawing-off of the present invention 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 only is the present invention's preferred embodiment, is not to limit practical range of the present invention with this, so the variation that all shapes according to the present invention, principle are done all should be encompassed in protection scope of the present invention.
