Description

Technical Field

[0001] The invention relates to a cage feeding mechanism. Background Art

[0002] Materials with poor fluidity, such as flour, bran powder, soybean meal, etc., cannot be fed by self-weight drop in automated production equipment. Even if self-weight feeding can be used in some environments, the desired accurate weight cannot be achieved. Therefore, most of these materials are fed by cage feeding. However, since these materials are easily piled up and compacted into blocks under the squeezing of the cage, they enter the metering mechanism, resulting in the inability to control the accuracy. Therefore, how to improve the existing accumulation and compaction during cage feeding and control the feeding accuracy is a problem to be solved. Summary of the invention

In view of the problems that arise, in the technical scheme, large and small discharge gates are arranged in stages, and then lowered through the hopper, and the speed of the dragon's rotation is controlled, and the agglomerates are squeezed through the small material gate. This solves the problem that the material is easily accumulated under the squeezing of the cage and enters the metering mechanism, resulting in the inability to control the accuracy.

[0017] A cage feeding mechanism, such as Figure 1 , Figure 2 and Figure 3 As shown, the cage feeding mechanism includes a logistics pipeline 1 which is usually arranged horizontally, in which a cage shaft 2 is arranged. The cage shaft 2 is supported in the logistics pipeline, and the cage shaft 2 is driven to rotate by a cage shaft motor 3. The cage shaft motor 3 can be a pneumatic motor or an electric motor. The output shaft of the cage shaft motor is output through a reducer 301. A spiral blade 201 is arranged around the cage shaft 2, the front end of the logistics pipeline is the discharge port, and a feed barrel 4 is arranged on the side of the tail end of the horizontal logistics pipeline 1. The cage shaft motor 3 drives the cage shaft 2 to rotate, and the rotating spiral blade 201 is used to push the material entering from the feed barrel 4 forward from the discharge port, wherein a gate is arranged at the discharge port at the front end of the logistics pipeline 1, and the gate is divided into two symmetrical left and right gates 5 and 6, the left gate 5 and the right gate 6, and the left and right gates 5 and 6 are rotated outward to open, and a discharge hopper 7 is arranged at the lower end of the discharge port, and the feed port at the upper end of the discharge hopper 7 is a horizontal rectangular port 701, and the lateral width of the horizontal rectangular port is greater than the logistics pipeline discharge port. The diameter of the material opening, the longitudinal width of the horizontal rectangular opening is not greater than half of the width of the left gate or the right gate. In order to provide a certain buffer for the falling materials, the lower end of the discharge hopper is tilted forward, and symmetrical left and right discharge gates 8 and 9 are arranged at the discharge opening at the lower end of the discharge hopper 7. The left discharge gate 8 and the right discharge gate 9 are connected and fixed to the lower ends of the left and right gates 8 and 9 through L-shaped connecting plates 10 and 11 respectively across the upper feed opening 701 of the discharge hopper 7. When the left and right gates 8 and 9 rotate outwards and open, they drive the left and right discharge gates 8, 9 and the L-shaped connecting plates 10 and 11 to open the upper feed opening and the lower discharge opening of the discharge hopper.

[0018] In the embodiment, the lower end of the discharge hopper is tilted forward at an angle of 30 to 45 degrees, and the longitudinal width of the outlet at the lower end of the discharge hopper is half of the longitudinal width of the feed inlet at the upper end. In this way, the left and right discharge gates 8 and 9 provided at the discharge outlet at the lower end of the discharge hopper form a small gate, and the two opposite left and right gates 5 and 6 are large gates.

[0019] The rotating structure of the left and right gates is: the left and right gates are respectively fixed on the two gate rotating shafts 12 and 13, and pneumatic telescopic cylinders 14 are respectively arranged on both sides of the upper end of the logistics pipeline. The cylinder bodies of the two pneumatic telescopic cylinders are fixed on the side walls of the feed barrel 4, and the telescopic arms of the two pneumatic telescopic cylinders are respectively hinged to one end of two rotating connecting rods 15, and the other ends of the two rotating connecting rods 15 are respectively connected and fixed to the two gate rotating shafts 12 and 13. The telescopic arm's extension and retraction drives the gate rotating shaft to rotate in the forward and reverse directions through the rotating connecting rod 15, and the forward and reverse rotation of the gate rotating shaft drives the left and right gates 5 and 6 to open and close.

[0020] Wherein: the extension length of the telescopic arm of the pneumatic telescopic cylinder controls the rotation angle of the rotating connecting rod, and the rotation angle is such that when the left and right gates are opened, the front ends of the left and right gates do not exceed the rotation angle of the longitudinal width of the feed port at the upper end of the discharge hopper. The half-opening of the left and right gates has the effect of allowing small compactions to fall directly into the discharge hopper and slide out from the lower port of the discharge hopper. Slightly larger compactions will affect the outflow from the lower port of the discharge hopper. Therefore, the half-opening of the left and right gates is used to squeeze and disperse the accumulated compacted materials and let them fall into the discharge hopper, thereby solving the problem that the materials are easily accumulated and compacted under the extrusion of the cage and enter the metering mechanism, resulting in the inability to control the accuracy. At the same time, in conjunction with the timed closing and opening, the plane sections of the L-shaped connecting plates 10 and 11 can also be used to extrude and crush the compacted blocks.

[0021] In order to eliminate the compaction of materials during feeding: a stirring shaft 16 is arranged in the middle of the feeding barrel, and stirring rods 17 are arranged around the stirring shaft; multiple stirring rods are arranged at a 360-degree angle, wherein: the output shaft of the cage shaft motor is directly connected to the cage shaft from the outer end of the logistics pipeline, and a driving sprocket 19 is also arranged on the output shaft of the cage shaft motor; a driven sprocket 20 is arranged on the outside of the feeding barrel, and the driving sprocket is connected to the driven sprocket arranged on the stirring shaft through a chain 21, and the output shaft of the cage shaft motor drives the cage shaft and the stirring shaft to rotate at the same time.

[0022] As shown in the figure, a dustproof box 22 is connected to the rear end of the logistics pipeline 1, and the dustproof box 22 covers the left and right gates 5, 6 and the discharge hopper 7. The cage shaft 2 passes through the joint of the left and right gates 5, 6 and is positioned and rotatably fixed on the end plate 2201 of the dustproof box 22 through the bearing 23. A rubber sealing strip is provided on the contact arc surface of the cage shaft 2 at the joint of the two gates 5, 6; an observation window 2202 is provided on the side end face of the dustproof box 22, and a dust removal port 2203 is provided on the top end face of the dustproof box 22, and the dust removal port 2203 can be connected to the dust removal pipeline of the factory.

[0023] The above-mentioned embodiment of the cage feeding mechanism sets the large and small discharge gates in stages, and then discharges the materials through the hopper, cooperates with the control of the rotation speed of the dragon, and limits the opening of the large gate to the longitudinal width of the small gate, thereby forming the conditions for extrusion and agglomeration, thereby solving the problem that the materials are easily accumulated and agglomerated under the extrusion of the cage and enter the metering mechanism, resulting in the inability to control the accuracy.
