Abstract
The invention discloses a dual-wheel roll dual-active friction drive belt material feeding device which overcomes the defects of the prior art and solves the slipping problem in the friction drive belt material feeding process. The structure of the device is characterized in that the device comprises a pair of lower roller and upper roller which are matched in a upper and lower way; the lower roller is connected with a power device and connected with the upper roller through a linkage system; and the belt material is arranged between the upper roller and the lower roller and goes forward by friction of the upper roller and the lower roller.
Description
Technical field
The present invention relates to the automatic field of mechanical device, relate in particular to a kind of dual-active friction drive feeding device.
Background technology
Friction-driven is the usual way of band feeding, and former type of drive generally is to adopt active and passive structure, is exactly the frictional wheel of band both sides, has only one to be driving wheel, promotes band and advances, and another just compresses band, is follower.As shown in Figure 1.The rotation of follower is to drive band by driving wheel, drives its rotation by band again.So follower is not only given band friction force forward, and provides friction force backward, stop the feeding of band.Two wheel loads must be tight more, and this prevention power is also big more.So main passive transmission, skidding often appears in band.The present invention addresses this problem exactly.
By retrieval, find a lot of patents relevant with friction-driven, such as: 200480030268.4,200410033231.9 and 200410059438.3 these three patents and the application have essential distinction, preceding two genus belt conveyers, one is intermittent delivery, and another is aerial conveying.They all be belt pack two on the certain distance belt wheel, the belt crank motion is by the belt convey materials.And two power wheels of the present invention are arranged force together up and down, drive two unidirectional advancing of band that pinch roller is middle up and down.Back one (200410059438.3) is the friction-driven running gear.
But they all are single initiatively transmissions.CN200810021610.4 magnetic-force compressed friction drive device by add the method for magnetic force on friction wheel, increases friction force, is not suitable for the non-magnetic material of transmission, as aluminium, and the cost height.CN02262752.9 scribbles one deck friction material on the surface of friction driving roller, drives the rotation of the little sand table of weaving, is not suitable for the charging of band.
Summary of the invention
Purpose of the present invention is exactly for overcoming the shortcoming of prior art, solve two-wheel to rolling the problem of skidding in the feeding of friction-driven band, a kind of dual-active friction drive feeding device that can effectively solve advantages such as the problem of skidding being provided.
For achieving the above object, the present invention adopts following technical scheme:
A kind of dual-active friction drive feeding device, it comprises a pair of bottom roller and the upper roller that cooperates up and down, and bottom roller is connected with engine installation, and bottom roller is connected by linkage with upper roller, and band places between upper roller and the bottom roller; Described engine installation comprises belt pulley, and belt pulley is connected with motor; Described linkage is made up of lower transmissioning gear and upper transfer gear, and wherein lower transmissioning gear is coaxial with bottom roller, and upper transfer gear is coaxial with upper roller, upper transfer gear and lower transmissioning gear engagement; Described upper roller floats, and is connected with holddown spring; The pitch circle diameter of the diameter of described two rollers and described two transmission gears equates.
Dual-active friction drive feeding device of the present invention is by bottom roller, upper roller, holddown spring, compositions such as upper transfer gear, lower transmissioning gear and belt pulley.Motor drives bottom roller by belt pulley and rotates, and rotates with the coaxial lower transmissioning gear of bottom roller simultaneously also just to have driven and lower transmissioning gear ingear upper transfer gear, and upper transfer gear then drives coaxial upper roller and rotates.
The invention has the beneficial effects as follows: simple in structure, easy to use, cost is low, can effectively solve the problem of skidding.
Description of drawings
Fig. 1 is a prior art constructions;
Fig. 2 is a structural representation of the present invention;
Fig. 3 is a transmission principle of the present invention.
Wherein, 1. bottom roller, 2. upper roller, 3. holddown spring, 4. upper transfer gear, 5. lower transmissioning gear, 6. belt pulley.
The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing and embodiment.
Among Fig. 2, Fig. 3, it comprises a pair of bottom roller 1 and the upper roller 2 that cooperates up and down, and bottom roller 1 is connected with engine installation, and bottom roller 1 and upper roller 2 are connected by linkage, and band places between upper roller 1 and the bottom roller 2.
Engine installation comprises belt pulley 6, and belt pulley 6 is connected with motor.Driving device is made up of lower transmissioning gear 5 and upper transfer gear 4, and wherein lower transmissioning gear 5 is coaxial with bottom roller 1, and upper transfer gear 4 is coaxial with upper roller 2, upper transfer gear 4 and lower transmissioning gear 5 engagements.Upper roller 2 also is connected with holddown spring 3.
Because gear-driven reverse property makes that going up bottom roller rotates in opposite directions, as shown in Figure 3.Like this, two rollers are all given band friction force forward.Owing to do not have friction force backward,, just can not produce and skid as long as holddown spring ensures to band friction force forward greater than strap tension.Practical application has proved this point.The key of this mechanism is to guarantee that the diameter of two rollers and the pitch circle diameter of two transmission gears equate.They can adopt paired method for processing to realize.In addition, the pitch circle diameter of gear otherwise, prevent from not press tightly band greater than the diameter of roller.
