Description

Technical Field

[0001] This utility model relates to the field of cat food processing technology, and in particular to a cat food crisping extrusion molding machine with adjustable porosity. Background Technology

[0002] Feed is a general term for the food consumed by all domesticated animals. In a narrower sense, feed mainly refers to the food raised in agriculture or animal husbandry. Feed includes more than ten varieties of feed ingredients, such as soybeans, soybean meal, corn, fishmeal, amino acids, miscellaneous meals, whey powder, oils, meat and bone meal, grains, and feed additives. In the production and processing of cat food, feed extrusion molding equipment is used to ensure that the processed cat food pellets or strips meet usage requirements.

[0003] However, the extrusion orifice diameter of current extrusion molding machines is determined by fixed modules. When different sizes of cat food are needed, the staff need to change different molds, which is quite troublesome. Based on this, this application proposes a cat food brittle extrusion molding machine with adjustable porosity, which can solve the above problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a cat food crisping extrusion molding machine with adjustable porosity.

[0005] The purpose of this utility model is achieved through the following technical solution: a cat food flaking extrusion molding machine with adjustable porosity, comprising a molding machine, an outer cylinder for discharging from the outlet of the molding machine, a plurality of circumferentially arrayed discharging slots being opened above the outer surface of the outer cylinder, a sealing inner cylinder that can reciprocate up and down being installed inside the outer cylinder, a plurality of circumferentially arrayed sealing blocks being installed on the outer surface of the sealing inner cylinder, which respectively slide in cooperation with the plurality of discharging slots, a sealing cap for sealing being installed inside the sealing inner cylinder, a plurality of circumferentially arrayed water outlets being opened above the outer surface of the sealing inner cylinder, and a first one-way valve being installed inside each of the plurality of water outlets, all of which face the inner wall of the outer cylinder.

[0006] Optionally, a fixing ring is installed at the bottom inside the outer cylinder of the discharge port, and fixing ears are installed around the inner wall of the fixing ring.

[0011] This adjustable porosity cat food extrusion molding machine has an outer discharge cylinder installed at the discharge port of the molding machine. The outer discharge cylinder is cylindrical in shape. Multiple circumferentially arranged discharge slots are opened on the upper part of the outer discharge cylinder. Inside the outer discharge cylinder, a sealing inner cylinder that can move up and down is installed. Multiple circumferentially arranged sealing blocks are installed on the outer surface of the sealing inner cylinder. These blocks slide and cooperate with the multiple discharge slots. By adjusting the position of the sealing inner cylinder, the size of the discharge slots can be changed, thereby achieving different material discharge amounts.

A sealing inner cylinder 3 that can move up and down is installed inside the discharge port outer cylinder 2. Multiple circumferentially arrayed sealing blocks 12 are installed on the outer surface of the sealing inner cylinder 3, which slide in cooperation with the multiple discharge slots 9 respectively. A sealing cap 5 for sealing is installed inside the sealing inner cylinder 3. Multiple circumferentially arrayed water outlet holes 14 are opened on the upper surface of the outer surface of the sealing inner cylinder 3. A first one-way valve 8 is installed inside each of the multiple water outlet holes 14, and they all face the inner wall of the discharge port outer cylinder 2.

[0022] As an optional technical solution of this utility model, a fixing ring 10 is installed at the bottom inside the outer cylinder 2 of the discharge port. Fixing ears 11 are installed around the inner wall of the fixing ring 10. Telescopic cylinders 4 are installed below the four fixing ears 11. The bottom of the sealing inner cylinder 3 is installed together with the output ends of the four telescopic cylinders 4. This facilitates the installation and disassembly of the entire device and provides an installation position for the telescopic cylinders 4, which can realize the up and down movement of the sealing inner cylinder 3.

[0023] As an optional technical solution of this utility model, a cavity 15 is opened inside the upper part of the inner wall of the sealing inner cylinder 3, and multiple water outlet holes 14 are all connected to the cavity 15. Multiple circumferential array water inlet holes 13 are opened on the inner side below the cavity 15, and a second one-way valve 7 is installed in each of them. This makes the position of each component reasonable and allows water to be sprayed from the water outlet holes 14.

[0024] As an optional technical solution of this utility model, a pipe 6 is installed below the cover 5. The pipe 6 extends from the outer cylinder 2 of the discharge port, which facilitates the supply of water to the inner cylinder 3 of the seal through the pipe 6.
