Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It should be understood that the description herein is provided for illustration and explanation of the invention and is not intended to limit the invention.

In the present invention, unless otherwise specified, the terms of orientation such as "upper, lower, inner, outer" and the like included in the terms only represent the orientation of the terms in a conventional use state or are colloquially known by those skilled in the art, and should not be construed as limiting the terms.

Referring to fig. 1-3 the utility model provides a screw classification collection device, this classification collection device include, drive arrangement, sieving mechanism, collecting box 4, box 1, workstation, bin outlet.

The top end of the box body is provided with a screw inlet 3, seven cavities are formed from top to bottom, a screening device is arranged in each cavity, screening discs 10 in the screening device are connected with supporting columns 5, and all the screening discs 10 rotate anticlockwise simultaneously.

The width size of the screening guide groove is gradually reduced from top to bottom, the spring stop 11 is arranged in the spiral guide groove 2, the distance between the spring stop 11 and the central support column 5 is different in each layer of spiral guide groove 2, and the distance between the spring stop 11 and the support column 5 is gradually increased from top to bottom.

Through the technical scheme, the guide groove and the spiral guide groove 2 are screened in a straight line mode by utilizing the size difference between the screws and the specification difference of the screws. The device has eight different screw bin outlet 12, rotates the mixing screw and utilizes the gravity and the structural feature of screw self to make the mixing screw can follow different bin outlet 12 and flow to eight kinds are distinguished for the screw. When the screening device is used, the motor 8 is started, and the rotating speed of the supporting column 5 is lower through the speed reducer 9, so that the screening disc 10 is driven to rotate anticlockwise. The mixing screws from M1.6 to M6 are poured into the device from the inlet funnel 3, the screws fall onto the first screening disk 10 after passing through the spiral guide groove due to gravity, when the first screening disk 10 rotates, the screws gradually fall onto the screening guide groove due to the blocking of the spiral guide groove, the screw tips of the screws with corresponding specifications face downwards, the screw caps are arranged on the upper portions and are born on the adjacent radial sieve rods, and the screw caps are positioned in the spiral guide groove. Thus, with the rotation of the screening disk 10 and the guiding resistance of the screening guide groove, the screws with corresponding specifications gradually get away from the supporting column 5 and move outwards until the screws fall into the corresponding collecting box. And screws smaller than the preset specification continue downwards. And for the screw of the corresponding specification which is not caught in the screening guide, since the height thereof is higher than that of the screw caught in the screening guide, it is stopped while passing through the spring stopper 11, thereby repeatedly adjusting the posture. For example, first layer sieving mechanism is at rotatory in-process, and the screw can meet the first spring dog of installing on spiral guide slot 2, and first spring dog can prevent not fixing the screw on first screening guide slot, because first spring dog and rotation action, the screw can adjust the gesture repeatedly, fall down on the second screening disc or when M6 screw card was completely on first screening guide slot on the first screening guide slot until the small size screw from first screening guide slot, can just pass through the spring dog smoothly, the M6 screw comes to first collecting box 4 from first discharge gate play afterwards. When the screw arrives on the second screening disc, second screening disc can drive the screw and be rotary motion, because there is spiral guide slot 2 second screening disc top, screw rotatory in-process can meet spiral guide slot 2, spiral guide slot 2 can force the screw to be centrifugal motion, the screw is kept away from support column 5 gradually, in rotatory in-process, the screw can meet the second spring dog of installing on spiral guide slot 2, second spring dog can prevent not fixing the screw on screening guide slot, because spring dog and rotation effect, the posture can be adjusted repeatedly to the screw, when falling down to the third screening disc or M5 screw is blocked completely on second screening guide slot from the second screening guide slot until small number screw, just can pass through the spring dog smoothly, M5 screw comes out in the second collecting box from the second bin outlet afterwards. Similarly, the M4 screw can come from the third bin outlet to the third collecting box, the M3.5 screw can come from the fourth bin outlet to the fourth collecting box, the M3 can come from the fifth bin outlet to the fifth collecting box, the M2.5 screw can come from the sixth bin outlet to the sixth collecting box, the M2 can come from the seventh bin outlet to the seventh collecting box, the M1.6 screw can fall from the seventh screening disc, go out through the eighth bin outlet to the eighth collecting box 4 through the discharge funnel.

In the present embodiment, the driving device includes a motor 8, a speed reducer 9, a support column 5; wherein, motor 8 is kept flat on the workstation, and motor 8 couples with reduction gear 9, and reduction gear 9 passes box 1 and reaches box 1 bottommost, and reduction gear 9 output passes through the gear vertical drive to support column 5 on, lets support column 5 can be anticlockwise rotary motion.

The screening device comprises a screening disc 10, a screening guide groove, a spiral guide groove 2 and a spring stop block 11; wherein, the total seven sieving mechanism, in order to separate eight kinds of screws smoothly, the screening guide slot width from top to bottom that sets up reduces gradually, and the spring dog 11 that sets up is installed in the spiral guide slot, and spring dog 11 bottom can set up to the inclined plane. Guarantee that the screw card can pass through spring stop 11 smoothly when screening the guide slot.

In order to ensure that the screw dropped from the upper layer can meet the spring stop 11 at the lower layer, the distance from the spring stop 11 installed from top to bottom to the central support column 5 is gradually increased.

In order to avoid the overlong length of the screw, the distance between the screening disks 10 on each layer is more than 80mm;

in order to effectively utilize the space and shorten the distance between the collecting boxes 4, the collecting boxes can be arranged on the box body 1 in a vertical and crossed way.

The above description is provided for the preferred embodiments of the present invention, but the present invention is not limited to the details of the above embodiments, and the technical idea of the present invention can be implemented by various simple modifications, which all belong to the protection scope of the present invention.

It should be noted that the various technical features described in the above embodiments can be combined in any suitable manner without contradiction, and in order to avoid unnecessary repetition, the present invention does not need to describe any combination of the features.

In addition, various embodiments of the present invention can be combined arbitrarily, and the disclosed content should be regarded as the present invention as long as it does not violate the idea of the present invention.
