Description

Technical Field

[0001] The utility model relates to the technical field of ring moulds, in particular to a ring mould for a feed machine. Background Art

[0002] With the development of society, the breeding industry has received more and more attention from the country, and the farms are getting bigger and bigger. The traditional feed is seriously wasted. Therefore, modern farms use compound feed to feed poultry and other animals. Compound feed needs to be made into granules during the production process. This part is completed by a granulator. A ring die is installed on the granulator, and an extrusion device is arranged inside the ring die. After the powder enters the ring die, it is squeezed out from the cylindrical hole on the ring die under the action of the extrusion device to form a column, and then it is cut off by the cutting knife located next to the ring die to form columnar particles.

[0003] Currently, the ring dies on the market are usually of one-piece design, and the ring die bodies of different sizes and apertures cannot be replaced according to actual needs, which has poor practicality. Utility Model Content

A slot for inserting the fixed cylinder, the telescopic rod and the limiting block is provided at the end of the connecting ring adjacent to the connecting ring at the same horizontal height, and a limiting hole for inserting the limiting block is provided at the top of the slot.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0023] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0024] like Figure 1 As shown, as a feed machine ring die of the utility model, it includes a ring die body 1, and a plurality of through holes 3 are opened on the ring die body 1. Figure 5 As shown, the through hole 3 is set as a stepped hole, the part of the through hole 3 close to the inside of the ring die body 1 is set as a straight hole, the part of the through hole 3 away from the inside of the ring die body 1 is set as an inclined hole, and a step is formed between the inclined hole and the straight hole, as shown in FIG. Figure 1 As shown, the outer wall of the ring die body 1 is covered with a plurality of through holes 3 by a connecting ring 2 connected by a buckle, and a discharge port 4 is opened at the position of the connecting ring 2 corresponding to the through hole 3, and a limiting cylinder 5 is fixed inside the discharge port 4, as shown in FIG. Figure 4 As shown, the inner diameter and outer diameter of the limiting cylinder 5 continuously decrease along the connecting ring 2 to the through hole 3, and the connection between the limiting cylinder 5 and the discharge port 4 is set to be arc-shaped, the smallest inner diameter of the limiting cylinder 5 is not greater than the diameter of the straight hole, and the diameter of the discharge port 4 is not greater than the diameter of the straight hole;

[0025] By inserting the limiting cylinder 5 into the through hole 3 until it contacts the straight hole on the stepped platform, the through hole 3 in the shape of a stepped hole and the limiting cylinder 5 with a continuously decreasing diameter ensure that the feed will not accumulate when entering the limiting cylinder 5 through the through hole 3. At the same time, the limiting cylinder 5 and the arc at the discharge port 4 are used for guidance to prevent the feed from accumulating at the connection when entering the discharge port 4 from the limiting cylinder 5, thereby ensuring that the feed can be stably extruded and formed.

[0026] like Figure 2 As shown, the connecting ring 2 is set to be semicircular, and two connecting rings 2 are spliced ​​to form a circle with an inner diameter equal to the outer diameter of the ring die body 1. Two connecting rings 2 can be provided. By covering all the through holes 3 with two connecting rings 2, the replacement efficiency can be improved. Only two connecting rings 2 need to be replaced. Figure 1As shown, six connecting rings 2 can also be provided, with two provided at the same horizontal height and three provided at the same vertical height. This arrangement can change the connecting ring 2 at a certain horizontal height in a single manner, thereby making the connecting ring 2 relatively independent, and further allowing the feed machine to produce feeds of different sizes at the same time, thereby improving the scope of application.

[0027] like Figure 2 As shown, a connecting ring 2 at the same level is fixed with a fixed cylinder 6 at both ends, a telescopic rod 7 is slidably arranged in the fixed cylinder 6, a limit block 9 is fixed at the output end of the telescopic rod 7, and a return spring 8 is wound around the telescopic rod 7. Figure 3 As shown, a slot 10 is provided at the end of another connecting ring 2 at the same horizontal height, and a limiting hole 11 is provided at the top of the slot 10. The fixing tube 6, the telescopic rod 7 and the limiting block 9 are inserted into the slot 10 by pressing the limiting block 9. The limiting block 9 is inserted into the limiting hole 11 by the rebound force of the reset spring 8, thereby completing the snap connection between the connecting rings 2. The snap connection allows the connecting ring 2 to be conveniently replaced, thereby changing the size of the feed without disassembling the ring die body 1, and has high practicality.

[0028] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
