Full-automatic subpackage pet feed production line
Technical Field
The invention relates to the field of feed production and processing, in particular to a full-automatic pet feed subpackaging production line.
Background
In a feed processing factory, a process of subpackaging the feed is carried out every day, and the subpackaging is to divide a pile of the feed to be packaged into a plurality of small parts, so that the subsequent wholesale and retail are facilitated. The traditional subpackaging method is that a bin filled with feed is vertically arranged on a support, a discharge hole for discharging the feed is formed in the lower end of the bin, the feed can be discharged from the discharge hole in the lower end of the bin by means of the gravity of the feed, a containing bag is arranged at the lower end of the bin, the feed discharged from the bin is received through the containing bag, and after one containing bag is filled with the feed, one containing bag is replaced to continue to receive the feed discharged from the bin. Dispensing by this method has two disadvantages: firstly, the feed in each containing bag is manually controlled to be equal, so that the feed in each containing bag cannot be ensured to be equal; secondly, in the time period of removing the full containing bag and putting the empty containing bag, the discharge hole at the lower end of the storage bin still discharges the feed continuously, which easily causes the feed to scatter around at the position below the storage bin.

The link mechanisms are provided with a plurality of groups, and the plurality of groups of link mechanisms are uniformly distributed between the annular bulge 8 and the lifting ring 10 around the axis of the rotating shaft 7.
The lantern ring 13 is provided with a through hole for the rotating shaft 7 to pass through, the rack 1 is provided with a supporting block 23, and the vertical plate 11 is connected to the supporting block 23 in a sliding mode through a dovetail groove; one end of a tension spring 14 is rotatably connected with the machine frame 1, the other end of the tension spring is rotatably connected with the vertical plate 11, and the tension spring 14 and the lifting ring 10 are positioned on the same side of the lantern ring 13.

The vertical plate 11 is provided with a square hole 24 for the belt transmission mechanism 2 to pass through, the cut-off plate 12 is positioned above the belt transmission mechanism 2, and the lower edge of the cut-off plate 12 is matched with the upper surface of the belt transmission mechanism 2 to cut off the feed on the belt transmission mechanism 2 to feed towards the charging barrel 4.
The working principle is as follows: firstly, an operator only needs to uniformly dump the feed on the belt transmission mechanism 2, an empty feed barrel 4 is placed on the sliding table 3, the feed is fed leftwards along with the work of the belt transmission mechanism 2, and the feed falls into the feed barrel 4 from the left end part of the belt transmission mechanism 2;
the first motor drives the rotating shaft 7 to rotate at a constant speed, the first connecting rod 18 and the second connecting rod 19 rotate along with the rotating shaft 7, and then the cylindrical pin 20 and the counterweight block 22 between the first connecting rod 18 and the second connecting rod 19 are subjected to centrifugal force to be far away from the axial direction of the rotating shaft 7, as shown in fig. 1, the axial convex ring 9 at the lower end of the sliding table 3 abuts against the middle part of the first connecting rod 18;
the feed in the feed cylinder 4 is heavier and heavier, the gravity action of the feed cylinder 4 on the sliding table 3 is also heavier and heavier, namely, the feed cylinder 4 with the heavier weight pushes the sliding table 3 to descend, the lower edge of the axial convex ring 9 at the lower end of the sliding table 3 pushes the first connecting rod 18 to rotate around the first hinge point 17, the counterweight block 22 at the lower end of the first connecting rod 18 approaches towards the axis direction of the rotating shaft 7, namely, the rotating radius of the counterweight block 22 is reduced, the second connecting rod 19 is further pushed to rotate, the second connecting rod 19 pushes the lifting ring 10 to descend, the lifting ring 10 pushes the sleeve ring 13 and the vertical plate 11 to descend together, and the intercepting plate 12 on the vertical plate 11 approaches towards the belt transmission; until the collar 13 abuts against the limiting ring 15, the cut-off plate 12 also abuts against the belt transmission mechanism 2, the cut-off plate 12 blocks the feed on the belt transmission mechanism 2, the feed barrel 4 is filled with the feed at the moment, and the belt transmission mechanism 2 cannot continuously transmit the feed to the feed barrel 4;
in addition, as the weight of the feed in the feed cylinder 4 is larger and larger, the feed cylinder 4 also gradually descends, the clamping pieces 5 on the two side walls of the feed cylinder 4 are clamped with the grooves in the conveying belt 6, once the clamping pieces 5 are clamped with the conveying belt 6, the movable conveying belt 6 drives the clamping pieces 5 and the feed cylinder 4 to slide in the sliding groove in the sliding table 3 together until the feed cylinder 4 filled with the feed is completely taken away from the sliding table 3; once the feed barrel 4 filled with the feed is separated from the sliding table 3, the sliding table 3 cannot be influenced by the gravity of the feed barrel 4, the counterweight 22 rotating at a constant speed is away from the axis of the rotating shaft 7, namely the counterweight 22 pulls the first connecting rod 18 and the second connecting rod 19 to rotate reversely and reset, the first connecting rod 18 pushes the sliding table 3 to ascend, the second connecting rod 19 pulls the lifting ring 10 to ascend, the vertical plate 11 and the lantern ring 13 ascend and reset under the action of the tension spring 14, and the shutoff plate 12 on the vertical plate 11 is separated from the belt transmission mechanism 2;
then, the operator places the next empty charging barrel 4 on the sliding table 3, and the belt transmission mechanism 2 can feed materials to the next charging barrel 4, so that automatic material distribution and blanking can be realized; since the lifting ring 10 can be driven to abut against the collar 13 only when the weight of the barrel 4 reaches the standard in each feed split charging process, and once the lifting ring 10 abuts against the collar 13, the cut-off plate 12 blocks the belt transmission mechanism 2 to continue feeding the barrel 4, so that the same amount of feed in each barrel 4 can be ensured.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the scope of the claims of the present invention should be included in the protection scope of the present invention.
