Description

Technical Field

[0001] The present invention relates to the technical field of feed production, and particularly relates to a uniform forming machine for feed pellets. Background Art

[0002] Feed is the general term for the food of all animals raised. More narrowly, generally, feed mainly refers to the food of animals raised in agriculture or animal husbandry. Feed includes more than a dozen varieties of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meals, additives, whey powder, oils and fats, meat and bone meal, grains, sweet sorghum, etc. In the production process of aquatic seedling (such as fish and shrimp) feed, it is necessary to granulate the feed.

[0003] For the traditional screw extruder, it first extrudes the feed into strip-shaped feed by using a pressing plate, and then cuts the strip-shaped feed into continuous granular form. However, since the amount of feed conveyed to the pressing plate per unit time cannot be controlled, the length of the extruded strip-shaped feed is large or small, which in turn affects the uniformity of the volume of the cut granular feed. Therefore, there is an urgent need for a uniform forming machine that extrudes the feed into continuous granular form. Summary of the Invention

[0004] To solve the technical problems existing in the above background art, the present invention provides a uniform forming machine for feed pellets.

[0005] The present invention is implemented by the following technical solutions: A uniform forming machine for feed pellets, including a housing. There is a partition in the housing, and the interior of the housing is sequentially isolated from top to bottom by the partition to form a first cavity and a second cavity.

[0006] The top of the partition has a pressing groove, and the bottom wall of the pressing groove is uniformly provided with a plurality of material holes communicating with the second cavity. A pressing plate that is in extrusion fit with the bottom wall of the pressing groove is vertically movably arranged in the first cavity.

[0009] An action device is arranged in the housing. Driven by the vertical movement of the pressing plate, the action device can guide the push plate to move towards the notch of the pressing groove when the pressing plate moves vertically downward.

[0010] As a further improvement of the above solution, a guide slope is arranged at the bottom of the second cavity and is located below the cutting assembly. An outlet is opened on the outer wall of the housing and corresponds to the lower end of the guide slope.

A first sprocket is sleeved on the outside of the first cylinder body, and a second sprocket is sleeved on the outer peripheral side of the second cylinder body. The first sprocket and the second sprocket are connected by chain drive;

[0014] When the pressing plate does not move downwards, the U-shaped opening of the U-shaped rod and the groove body of the through groove are in a cross-holding state.

There is a partition board 8 inside the housing 1, and the inside of the housing 1 is sequentially isolated from top to bottom by the partition board 8 to form a first cavity and a second cavity.

[0032] At the top of the partition board 8, there is a pressing groove 9. A plurality of material holes 10 communicating with the second cavity are uniformly opened on the bottom wall of the pressing groove 9. A pressing plate 7 that is vertically movable and is in extrusion fit with the bottom wall of the pressing groove 9 is arranged in the first cavity.

[0033] A cutting assembly for cutting the material is arranged in the second cavity and is located below the material holes 10.

[0034] A feed pipe 2 is arranged at the top of the housing 1. A material guiding plate 35 that is inclined and is located below the discharge end of the feed pipe 2 is arranged in the first cavity. A pushing plate 24 is arranged at the top of the partition board 8, and the material pushing surface of the pushing plate 24 corresponds to the lower end of the material guiding plate 35.

[0035] An actuating device is arranged inside the housing 1. Driven by the vertical movement of the pressing plate 7, the actuating device can guide the pushing plate 24 to move towards the notch direction of the pressing groove 9 when the pressing plate 7 moves vertically downward.

[0036] A material guiding slope 12 is arranged at the bottom of the second cavity and is located below the cutting assembly. A discharge port 3 corresponding to the lower end of the material guiding slope 12 is opened on the outer wall of the housing 1.

[0037] A linear motor is installed at the top of the housing 1. A transmission rod 4 is connected to the output shaft of the linear motor. The bottom end of the transmission rod 4 is connected to a connecting rod 6, and the bottom of the connecting rod 6 is connected to the top of the pressing plate 7.

[0038] The actuating device includes a vertical plate fixed to the top of the partition plate 8. A second cylinder body 23 is rotatably arranged on the vertical plate.

[0040] When the pressing plate 7 does not move downward, the U-shaped opening of the U-shaped rod 5 and the groove body of the through groove 15 are in a cross-holding state. When the pressing plate 7 moves downward, the end of the U-shaped rod 5 close to the transmission rod 4 is in contact and pressure fit with the inclined surface, so as to force the moving plate 13 to horizontally move towards the direction of the first cylinder body 18.

When the pressing plate 7 does not move downward, the feeding end of the material passing port 14 corresponds to the discharging end of the feeding pipe 2, and the discharging end of the material passing port 14 corresponds to the high end of the guiding plate 35; when the pressing plate 7 moves downward, the feeding end of the material passing port 14 and the discharging end of the feeding pipe 2 are mutually displaced, so as to completely block the discharging end of the feeding pipe 2 by the top plate surface of the moving plate 13.

[0043] The cutting assembly includes a cutting knife 11. A vertical rod 33 is installed at the rotation center of the cutting knife 11. A support arm 30 is arranged on the inner side wall of the second cavity. The bottom of the vertical rod 33 is rotatably inserted on the support arm 30.

[0044] A third sprocket 27 is sleeved on the outer side of the second cylinder 23, a fourth sprocket 28 is rotatably provided on the side wall of the second cavity, the third sprocket 27 and the fourth sprocket 28 are connected via a corresponding chain transmission, a first bevel tooth 29 is coaxially fixed on the fourth sprocket 28, a second bevel tooth 31 matching the first bevel tooth 29 is rotatably provided on the support arm 30, a fifth sprocket 32 ​​is coaxially fixed on the second bevel tooth 31, a sixth sprocket 34 is coaxially fixed on the vertical rod 33, and the fifth sprocket 32 ​​and the sixth sprocket 34 are connected via a corresponding chain transmission.

[0045] A bearing is provided on the support arm 30 , and the inner ring of the bearing is sleeved and fixed on the outer peripheral side wall of the bottom of the vertical rod 33 .

[0046] The working principle of this embodiment:

[0047] Initially, the feed port 14 of the movable plate 13 corresponds to the discharge end of the feed pipe 2, and the push plate 24 is on the side away from the notch of the pressing groove 9. The feed is put into the feed pipe 2, and the feed passes through the discharge end of the feed pipe 2 and through the feed port 14 and the guide plate 35 to the push surface of the push plate 24 at the top of the partition 8.

[0048] Then, the output shaft of the linear motor is controlled to drive the transmission rod 4 to move downward. The transmission rod 4 not only drives the pressing plate 7 to move downward through the U-shaped rod 5 and the connecting rod 6, but also the downward movement of the U-shaped rod 5 also causes the upper end of the rod to touch the inclined surface, forcing the movable plate 13 to move horizontally toward the first cylinder 18, which will cause the feeding port 14 and the discharge end of the feed pipe 2 to be misaligned with each other, forcing the discharge end of the feed pipe 2 to be blocked and unable to continue to discharge, and will drive the protrusion 19 of the ejector rod 17 to continuously rub and squeeze the axially spiral groove 20, forcing the first cylinder 18 to rotate unidirectionally, and the first cylinder 18 drives the first sprocket 21 to rotate, and the first sprocket 21 drives the second sprocket 22 and the second cylinder 23 to rotate through the chain, so that the second cylinder 23 and the screw 25 interact with each other, and under the limiting action of the second telescopic rod 26, the push plate 24 is forced to push the feed to the pressing groove 9, so that the pressing plate 7 squeezes the feed compound hole 10 into a strip and enters the second cavity. During this period, the second cylinder 23 also drives the third sprocket 27 to rotate, and the third sprocket 27 drives the fourth sprocket 28, the first bevel gear 29, the second bevel gear 31 and the fifth sprocket 32 ​​to rotate through the chain. The fifth sprocket 32 ​​drives the sixth sprocket 34, the vertical rod 33 and the cutting knife 11 to rotate through the chain to cut the strip-shaped material into granules. The granular feed falls to the guide slope 12 and moves along the guide slope 12 to the discharge port 3 for collection.

[0049] When the output shaft of the linear motor drives the transmission rod 4 to move upward, the pressing plate 7 moves upward and leaves the bottom of the pressing groove 9, the push plate 24 is reset and the feeding port 14 of the movable plate 13 returns to the position corresponding to the discharge end of the feed pipe 2 for unloading again.

[0050] By controlling the output shaft of the linear motor to drive the transmission rod 4 to reciprocate vertically, not only the continuous forming production of feed pellets is realized, but also the amount of feed input into the housing 1 per unit time can be controlled to ensure the uniformity of feed pellets.

[0051] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the scope of protection required by the present invention.
