Abstract
The utility model relates to an adjustable sieve forming machine which comprises a rack, an upper press roller, lower press rollers, motors and a drive mechanism. The adjustable sieve forming machine is characterized in that three lower press rollers are arranged below the upper press roller, automatic adjusting devices are mounted on rotating shafts of the three lower press rollers, and each automatic adjusting device comprises a small servo motor, a screw, a screw nut, an adjusting rod, a sleeve and a spring. Compared with conventional roll bending forming equipment, the adjustable sieve forming machine has better adaptability and adjustability to different sizes of sieves made of different materials and has higher safety performance and vibration damping performance.
Description
Technical field
The utility model relates to the sieve former of a kind of pulverizing or paddy husking.
Background technology
In paddy husking or other disintegrating apparatus, often to use sieve.The manufacture craft of sieve is as follows: first, the steel disc of cutting suitable dimension, puts into by steel disc the sieve aperture that punch press is gone out various shapes, then sieve with holes is put into curved roller curves curve form.Existing curved roller exists that bending radius can not regulate automatically, do not have in BENDING PROCESS elasticity, vibration damping poor, without shortcomings such as safety overloads.
Utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of adjustable sieve forming machine device is provided.
The utility model is achieved by the following technical solutions: a kind of adjustable sieve forming machine, comprise frame, upper nip drum, lower press rolls, motor, transmission mechanism, it is characterized in that: described upper nip drum below is provided with three lower press rolls, self-checking device is all installed in the rotating shaft of described three lower press rolls, and described self-checking device comprises servo small machine, screw mandrel, feed screw nut, adjusting rod, sleeve, spring.On the output shaft of described servo small machine, screw mandrel is installed, the feed screw nut that can move up and down along it is housed on described screw mandrel, described screw mandrel becomes spiral to coordinate with feed screw nut, on described feed screw nut, be installed with adjusting rod, described adjusting rod centre position is provided with the sleeve playing the guiding role, between described adjusting rod and sleeve for being slidably connected.
Further, the top of described adjusting rod has been provided with the spring of safety and elastic reaction.
From traditional curved to roll former different, upper nip drum described in the utility model below is provided with three lower press rolls, and self-checking device is all installed in the rotating shaft of described three lower press rolls.While starting operation under the control of servo small machine at control program, by screw mandrel, drive and become with it the feed screw nut that spiral coordinates to rise or decline, thereby promote adjusting rod, along sleeve, lower press rolls is carried out to up-down adjustment, to when adjusting to desired location, it is out of service that control program is controlled servo small machine.Three cover adjusting devices can regulate independently, and follow procedure is adjusted bending radius size automatically, and its flexibility is good, can regulate according to the sieve of different materials, different sizes, have good adjustability.In addition, the top of adjusting rod has been provided with the spring of safety and elastic reaction, when lower press rolls withstands shocks load or when bending load surpasses output power of motor, spring has good buffer shock-absorbing effect and safeguard protection effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In accompanying drawing: 1-upper nip drum, 2-lower press rolls, 3-spring, 4-sleeve, 5-adjusting rod, 6-feed screw nut, 7-screw mandrel, 8-servo small machine.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
A kind of adjustable sieve forming machine, comprise frame, upper nip drum 1, lower press rolls 2, motor, transmission mechanism, described upper nip drum 1 and lower press rolls 2 are arranged in frame by bearing, described motor is arranged on frame lower, and motor drives nip drum 1 or 2 pairs of sieves of lower press rolls to carry out bending forming by transmission mechanism.
As shown in Figure 1, upper nip drum 1 below is provided with three lower press rolls 2, and self-checking device is all installed in the rotating shaft of described three lower press rolls 2, and described self-checking device comprises servo small machine 8, screw mandrel 7, feed screw nut 6, adjusting rod 5, sleeve 4, spring 3.Screw mandrel 7 is installed on the output shaft of servo small machine 8, the feed screw nut 6 that can move up and down along it is housed on described screw mandrel 7,6 one-tenth spirals of described screw mandrel 7 and feed screw nut coordinate.On feed screw nut 6, be installed with adjusting rod 5, described adjusting rod 5 centre positions are provided with the sleeve 4 playing the guiding role, between adjusting rod 5 and sleeve 4 for being slidably connected.While starting operation under the control of servo small machine 8 at control program, by screw mandrel 7, drive and become with it the feed screw nut 6 that spiral coordinates to rise or decline, thereby promote adjusting rod 5, along 4 pairs of lower press rolls of sleeve 2, carry out up-down adjustment.Three cover adjusting devices can regulate independently, and follow procedure is adjusted bending radius size automatically, and its flexibility is good, can regulate according to the sieve of different materials, different sizes, have good adjustability.
In addition, the top of adjusting rod 5 has been provided with the spring 3 of safety and elastic reaction, when lower press rolls 2 withstands shocks load or when bending load surpasses output power of motor, spring 3 has good buffer shock-absorbing effect and safeguard protection effect.
Compare with traditional curved former that rolls, the utility model is better to adaptability, the adjustability of the sieve of different materials, different sizes, and its security performance and damping property are higher.
