Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with accompanying drawings 1, 2, 3 and 4 and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

A batch quantitative feeding device, including two rows of left and right and symmetrically arranged filling funnels 1, a filling tray 2 is arranged directly below each filling funnel 1, and the bottom of the filling funnel 1 is a discharge pipe 3 A switch valve assembly 4 is installed on the discharge pipe 3, two rows of switch valve assemblies 4 are arranged oppositely and a magnet controller 5 is arranged at the central axis position between them, and the switch valve assembly 4 includes a guide cylinder 41 and an I-shaped Part 42, the middle of the shaped part 42 is a cross bar 421, one end is an adsorption block 422 facing the magnet controller, and the other end is a tail block 423, the cross bar 421 passes through the discharge pipe 3 and the cross bar 421 opens There is a vertical through hole 43, the tail block 423 is located in the guide cylinder 41 and a spring 44 is arranged between the tail block 423 and the bottom of the guide cylinder 41, the magnet controller 5 includes a magnet block 50 and two front and rear Fixed plate 51, screw rod 52 and two slide bars 53 arranged in parallel with screw rod 52 are installed between two fixed plates 51, described magnet block 50 passes through described screw rod 52 and two slide bars 53, two fixed plates Between 51 there are symmetrically arranged bar blocks 54 on the left and right, the bar blocks 54 are located outside the adsorption block 422, and the batch quantitative feeding device also includes a driving device for driving the screw to rotate.

Working principle: Pour the material to be divided into two rows of filling funnels. At this time, the spring in the guide cylinder provides the elastic force greater than or equal to zero to the left of the workpiece. The switch valve assembly is closed and the material cannot flow out. Power on the drive device, the drive device drives the screw to rotate at a certain speed, and the magnet block passing through the screw rod moves along the slide bar at a constant speed under the action of traction, and the magnet block gradually approaches a pair of switch valve assemblies. When the adsorption block of the switch valve assembly When the magnetic attraction force is strong enough, the adsorption block drives the entire workpiece to be adsorbed to the direction of the magnet block until it touches the bar stopper of the magnet controller. The material pipe and the switching valve assembly are in the open state, and the material flows into the material tray directly below the material funnel under the action of gravity, and the spring between the bottom of the guide cylinder and the tail block of the workpiece is in a compressed state. When the magnet block gradually moves away from the pair of switch valve assemblies, the magnetic attraction force of the magnet block to the adsorption block gradually decreases. When the spring force in the guide cylinder is greater than the magnetic attraction force, the workpiece moves to the left to the limit position under the action of the resultant force , the vertical through hole on the cross bar of the workpiece gradually does not communicate with the discharge pipe, and the switch valve assembly is finally in a closed state, completing a quantitative packaging work. During the uniform linear motion of the magnet block along the slide bar, the magnet block continuously absorbs the adjacent adsorption block, and the adsorption block bounces back to the original state after moving away. One linear motion of the magnet block can complete the left and right rows of material funnels on the movement route. Quantitative feeding operation, the reciprocating linear motion of the magnet block can realize the quantitative packaging of materials in batches, which significantly improves the automatic production efficiency, and can also control the moving speed of the magnet block to meet the quantitative operation of different material volume requirements, which is flexible and convenient.

As a preferred structure of the batch quantitative feeding device, as shown in Fig. 1, Fig. 2 and Fig. 3, Fig. 4, there are four bar-shaped stoppers 54 in total, two in the upper layer and two in the lower layer.

The drive A second conveyor belt 64 is sleeved between the output shaft of the motor 61 and the reduction wheel 62 .

The two ends of the bar stopper can move horizontally in the chute, and the C-shaped piece limits the limit position of the bar stopper's outward movement. The limit position of the direction movement of the magnet controller will further affect the communication rate between the vertical through hole on the cross bar of the workpiece and the discharge pipe, so as to achieve the effect of controlling the material flow. Adjust the nut to fix the C-shaped piece, and put an I-shaped spacer of appropriate width in the middle of the bar-shaped stopper to achieve the purpose of fixing the bar-shaped stopper, and at the same time protect the bar-shaped stopper from being easily deformed after repeated collisions with the adsorption blocks. question.
