Description

The screening plant of handware

Technical field

The utility model material sieving technology field, more particularly to a kind of screening plant for being used to sieve handware.

Background technology

As depicted in figs. 1 and 2, screening plant of the prior art generally includes base 1, is arranged on the material of the top of base 1 Bucket 2, the impulse mgnet 3 being arranged between hopper 2 and base 1, the multiple springs being inclined between hopper 2 and base 1 Piece 4；Hopper 2 has been internally formed from the spiralling guide groove 5 in its bottom.Impulse mgnet 4 can cause hopper 2 to shake vertically Dynamic, the vertical vibrating of hopper 2 changes the distance between hopper 2 and base 1, so that spring leaf 5 and base 1 and hopper Angular dimension alternate change between 2, under the drive of spring leaf 4, hopper 2 does the reciprocal fortune of certain corner in the circumferential simultaneously Dynamic, the synthesis of the vertical motion and the reciprocating rotation of hopper 2 of hopper 2 can make the parts 6 to be sieved, as handware is continuous Along the spiral of guide groove 5.

For hopper 2 in vertical motion, it is substantially carried out two actions, when motion straight up, second, straight down Motion.When moving straight up, parts 6 to be sieved with funnel 2 under the drive of spring leaf 4 towards the side of spiral climbing To rotation, now, make parts 6 to be sieved and funnel 2 that there is same rotational speed as far as possible, to make parts 6 be transported to by funnel 2 Certain circumferential position in horizontal direction；When moving straight down, funnel 2 declines under the drive of spring leaf 4 towards spiral Direction rotate, now, make the remains stationary of parts 6 to be sieved as far as possible, in other words as far as possible make funnel 2 and parts 6 to be sieved Differential is kept, so that parts to be sieved 6 are maintained at relative base 1 or the circumferential position on ground is constant, in this way, zero to be sieved Part 6 just climbs one section of guide groove.

However, spring leaf 4 of the prior art is fixedly connected or is hinged with base 1 and the bottom of funnel 2 so that in pulse In the presence of electromagnet 3, funnel 2 is vertically movable direct and the non-cushioned direction towards spiral climbing rotates, and due in pulse In the presence of magnet 3, as shown in Fig. 2 the acceleration of funnel 2 vertically movable (acceleration) is larger, so that the rotation of funnel Acceleration is larger, and the larger acceleration overcomes the friction between parts 6 and funnel 2 to be sieved so that parts 6 and leakage Produce differential (speed of parts be less than the speed V2 of funnel 2 for V1) between bucket 2, the differential prevents funnel 2 from by parts 6 It is transported to its maximum circumferential position, that is to say, that the circumferential stroke that each funnel 2 transports is smaller, so as to have impact on 2 turns of funnel The dynamic efficiency for transporting parts 6 to be sieved.

Utility model content

For above-mentioned technical problem present in prior art, the utility model provides a kind of screening dress of handware Put.

In order to solve the above technical problems, the technical solution adopted in the utility model is：

A kind of screening plant of handware, including base, the funnel above the base, both ends connect respectively it is described Funnel with the base and the multiple spring leafs being in tilted layout in the same direction in the circumferential and positioned at the funnel with it is described Impulse mgnet between funnel, the position that the bottom of the funnel corresponds to the upper end of the spring leaf are provided with lead, The lead is provided at both ends with two limiting plates；The lower end of the spring leaf is hinged or is fixedly connected with the base, described The upper end of spring leaf is arranged on the lead and can slided between two limiting plates along the lead；It is described to lead Spring is arranged with to post, the spring is arranged on the spring leaf side opposite with incline direction.

Preferably, the upper end of the spring leaf is hinged with sleeve, and the sleeve is set on the lead.

Compared with prior art, the beneficial effect of the screening plant of handware of the present utility model is：The utility model profit Cause that the rotation acceleration increase of funnel is slower with the cushioning effect of spring, turn so that parts to be sieved are synchronous with funnel It is dynamic so that parts to be sieved are transported to the circumferential travel position of maximum by funnel.

Embodiment

It is below in conjunction with the accompanying drawings and specific real to make those skilled in the art be better understood from the technical solution of the utility model Mode is applied to elaborate to the utility model.

As shown in figure 4, preferred embodiment of the present utility model provides a kind of screening plant of handware, the handware Screening plant is used to sieve handware, such as bolt, nut.The screening plant of the handware includes base 10, positioned at the bottom The funnel 20 of the top of seat 10, both ends connect the funnel 20 and the base 10 and tilt cloth in the same direction in the circumferential respectively The multiple spring leafs 40 and the impulse mgnet 30 between the funnel 20 and the funnel 20 put, the funnel 20 The position that bottom corresponds to the upper end of the spring leaf 40 is provided with lead 72, and the lead 72 is provided at both ends with two limits Position plate 71；The lower end of the spring leaf 40 is hinged or is fixedly connected with the base 10, and the upper end of the spring leaf 40 is arranged on It can be slided between two limiting plates 71 on the lead 72 and along the lead 72；It is arranged on the lead 72 There is spring 74, the spring 74 is arranged on the spring leaf 40 side opposite with incline direction.

When impulse mgnet 30 is applying upward power on direction to funnel 20 straight up, as shown in figure 5, funnel 20 Speed from 0 rapid increase, now, the upward motion of funnel 20 causes spring leaf 40 from static quickly towards its inclined direction Opposite direction swing, make it that spring 74 is compressed because there is provided the swing of above-mentioned spring 74, spring leaf 40, so that spring The motion of piece 40 is being converted to when circumferentially rotating of funnel 20, and the motion of spring leaf 40 is buffered (as shown in fig. 6, working as by spring 74 When the swing of spring leaf 40 tends towards stability, spring 74 progressively recovers former long, and this change in process also compares mitigation, no longer superfluous herein State), that is to say, that spring leaf 40, which is not moved directly, passes to funnel 20, but is transmitted by spring 74, bullet By in compression process, spring 74 is relatively slowly increased spring 74 to the power of the circumferential direction of funnel 20, so that funnel 20 is in circumferential side Upward acceleration is increased relatively slowly, so that speed is increased less, the acceleration of funnel 20 can not overcome to be sieved zero Frictional force between part 60 and guide groove 50, as shown in fig. 7, so that parts to be sieved 60 rotate at the same speed with funnel 20 (speed is V0), parts 60 to be sieved are farthest transported to the position of circumferential maximum by funnel 20.

The utility model make it that the rotation acceleration increase of funnel 20 is slower using the cushioning effect of spring 74, so that Parts 60 to be sieved and the synchronous axial system of funnel 20 so that parts 60 to be sieved are transported to the circumferential stroke of maximum by funnel 20 Position.

Preferably, the upper end of the spring leaf 40 is hinged with sleeve 73, and the sleeve 73 is set on the lead 72.

Above example is only exemplary embodiment of the present utility model, is not used in limitation the utility model, and this practicality is new The protection domain of type is defined by the claims.Those skilled in the art can be in essence of the present utility model and protection domain It is interior, various modifications or equivalent substitution are made to the utility model, this modification or equivalent substitution also should be regarded as new in this practicality In the protection domain of type.
