Description

Technical Field

[0001] This utility model relates to the field of pet food processing technology, specifically to an extrusion mold for pet food processing. Background Technology

[0002] Pet food is food specifically designed for pets, primarily providing the basic nutrients needed for their survival, growth, development, and health. As people's living standards improve, more and more people are keeping pets, leading to higher demands for pet food. Pet food comes in various shapes to suit different pet sizes, such as strips, flakes, and granules. Factories typically use extruders to extrude pet food into these shapes. One end of the extruder is connected to an extrusion pipe, and the other end is connected to multiple extrusion dies. During processing, the food is placed inside the extruder, and the extruder's internal power system forces the food through the dies. Most extruders have a single integrated die head, which is inconvenient when producing different shapes of food.

[0003] A search revealed a utility model patent with publication number CN221152910U, which discloses an extrusion mold for pet food processing, belonging to the field of pet food processing. The mold includes an extrusion cylinder and a mold head detachably mounted at the end of the extrusion cylinder. Two fixing blocks are fixedly connected to both sides of the extrusion cylinder, and T-shaped mounting blocks are fixedly connected to both sides of the mold head. Each T-shaped mounting block has an internal receiving groove containing a spring. Both ends of the spring are fixedly connected to snap-fit ​​blocks. Each fixing block has an internal snap-fit ​​hole, and a movable block is inserted into one end of the snap-fit ​​hole. Through the arrangement of the fixing blocks, T-shaped mounting blocks, springs, snap-fit ​​blocks, snap-fit ​​holes, and movable blocks, when disassembling the mold head, simply pressing the movable block pushes the snap-fit ​​blocks out of the snap-fit ​​holes. By using a mold head that can be detached from the extrusion cylinder, the mold head can be disassembled and replaced when different shapes of food need to be produced, facilitating the production of pet food of different shapes.

[0004] The aforementioned patent merely employs a mold head that can be detached from the extrusion cylinder. When different shapes of food need to be produced, the mold head can be disassembled and replaced, making it convenient to produce pet food of different shapes. However, it cannot fully utilize the texture of the inner surface of the mold selectively, cannot achieve the output of different surface textures of food from the same mold, does not facilitate the demonstration of the device's high efficiency and practicality, and cannot meet the different taste requirements of different pets.

[0005] Therefore, it is necessary to invent an extrusion die for pet food processing to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an extrusion mold for pet food processing. By adding a mold head with a smooth inner surface and a mold lip with an adjustable inner surface texture, a control adjustment column can drive a cylinder to slide along a track within an arc frame. The texture grooves on the inner surface of the cylinder can be selected as needed, and with the addition of raised strips, spherical texture strips, and triangular texture strips, different surface textures can be output from the same mold to meet the different taste preferences of various pets. This addresses the differences between dogs' chewing preferences and cats' licking preferences, thus solving the problems of existing technologies that cannot fully selectively utilize the texture of the inner surface of the mold, cannot output different surface textures from the same mold, are not conducive to demonstrating the efficiency and practicality of the device, and cannot be adapted to the different taste preferences of various pets.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an extrusion die for pet food processing, comprising a die head and a die lip. The die head is threadedly connected to an extrusion cylinder via a connecting sleeve, which is fixedly connected to the die head. The end of the die head is hinged to a die lip via a flexible node. The flexible node includes a support one and a support two, which are rotatably connected. The support one is detachably connected to the die head via screws, and the support two is detachably connected to the die lip via screws. An arc-shaped frame is fixedly connected to the inner wall of the die lip. Raised strips are equidistantly fixed to the inner surface of the arc-shaped frame, with multiple raised strips interleaved. A cylinder is slidably disposed inside the arc-shaped frame, and a ring is fixedly connected to the side of the cylinder. The adjusting column has texture model one and texture model two equidistantly arranged inside the cylinder. Multiple texture model one and texture model two are symmetrically distributed about the central axis of the cylinder. Texture model one includes a cavity one, which is opened inside the cylinder. A slider one is slidably arranged inside the cavity one. The side of the slider one is fixedly connected to the inner wall of the cavity one by a spring one. A spherical texture strip is fixedly connected to the side of the slider one away from the spring one. Texture model two includes a cavity two, which is opened inside the cylinder. A slider two is slidably arranged inside the cavity two. One side of the slider two is fixedly connected to the inner wall of the cavity two by a spring two. A triangular texture strip is fixedly connected to the other side of the slider two.

[0008] Preferably, an O-ring is provided between the mold head and the mold lip, and the O-ring is fixedly connected to the mold lip.

[0009] Preferably, a connecting block is fixedly connected to the side of the mold head, and a limiting cavity is formed inside the connecting block, with a sliding groove formed on the side of the limiting cavity.

[0010] Preferably, a limiting block is slidably disposed inside the limiting cavity, one side of the limiting block is fixedly connected to the inner wall of the limiting cavity by a spring, and the other side of the limiting block is fixedly connected to a retaining block.

[0011] Preferably, an operating rod is fixedly connected to the side of the limiting block, and the operating rod matches the slide groove.

[0012] Preferably, a connecting arm is fixedly connected to the side of the mold lip, and a slot is provided on the side of the connecting arm, which matches the insertion block.

[0013] Preferably, the flexible node includes a first support and a second support. The first support is detachably connected to the mold head by screws, and the second support is detachably connected to the mold lip by screws.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. By adding a mold head with a smooth inner surface and a mold lip that can change the texture of the inner surface, the cylinder can be moved along the track inside the arc frame by using the control adjustment column. The texture grooves on the inner surface of the cylinder can be selected as needed. With the setting of raised strips, spherical texture strips and triangular texture strips, different surface textures (such as rough, smooth, stripes) can be output by the same mold to meet the different taste requirements of different pets. It can take into account the difference between dogs' preference for chewing (rough texture) and cats' preference for licking (smooth + grooves).

[0016] 2. By setting and using limit blocks, springs, operating rods, slides, insertion blocks, connecting arms, and slots, the insertion state of the insertion blocks and slots can be adjusted. The use of the die lip can be selected. When the die lip is separated from the die head, pet food with a smooth surface can be extruded using the die head. When the die head is connected to the die lip, after the food comes into contact with the texture of the inner surface of the die lip, food with uneven texture can be output to meet the different taste requirements of pets.

Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] This utility model provides, for example Figure 1-8The illustration shows an extrusion die for pet food processing, comprising a die head 1 and a die lip 5. The die head 1 is threadedly connected to an extrusion cylinder 3 via a connecting sleeve 2, which is fixedly connected to the die head 1. The end of the die head 1 is hinged to the die lip 5 via a flexible node 4. The flexible node 4 includes a first support 401 and a second support 402, which are rotatably connected. The first support 401 is detachably connected to the die head 1 by screws, and the second support 402 is detachably connected to the die lip 5 by screws. An arc-shaped frame 6 is fixedly connected to the inner wall of the die lip 5. Raised strips 7 are equidistantly fixed to the inner surface of the arc-shaped frame 6, with multiple raised strips 7 interlaced. A cylinder 8 is slidably disposed inside the arc-shaped frame 6, and an adjusting column 9 is fixedly connected to the side of the cylinder 8. Inside the cylinder 8, texture models 10 and 21 are equidistantly arranged. Texture models 10 are concentrated in one half of the cylinder 8, and texture models 21 are concentrated in the other half. Multiple texture models 10 and 21 are symmetrically distributed about the central axis of the cylinder 8. Texture model 10 includes a cavity 12, which is located inside the cylinder 8. A slider 13 is slidably disposed inside the cavity 12. The side of the slider 13 is fixedly connected to the inner wall of the cavity 12 by a spring 14. A spherical texture strip 15 is fixedly connected to the side of the slider 13 away from the spring 14. Texture model 21 includes a cavity 26, which is located inside the cylinder 8. A spherical texture strip 15 is slidably disposed inside the cavity 21. A sliding block 17 is provided, with one side of the sliding block 17 fixedly connected to the inner wall of the mold cavity 16 via a spring 18. A triangular textured strip 19 is fixedly connected to the other side of the sliding block 17. The thread on the inner surface of the connecting sleeve 2 engages with the thread on the outer wall of the extrusion cylinder 3, allowing the mold head 1 and extrusion cylinder 3 to be detachable for easy replacement of the mold head 1. This is suitable for processing pet food of different shapes. The cylinder 8 slides within the arc-shaped frame 6 using a manually operated adjusting column 9, allowing selection of texture model 10 or texture model 21. The raised strip 7 evenly distributes elongated grooves on the outer surface of the food. When the spherical textured strip 15 slides and hides within the arc-shaped frame 6, it retracts into the mold cavity 12. The spherical structure does not hinder the telescopic adaptation movement within the arc frame 6. When the cylinder 8 slides outside the arc frame 6, it will rebound due to the expansion of spring 14, making the head of the spherical texture strip 15 consistent with the protrusion of the convex strip 7, so that the grooves on the outer surface of the food are evenly distributed during extrusion. Among them, the triangular texture strip 19 is pointed, which increases the diversity of the texture grooves on the food surface and adapts to the different taste preferences of pets. It can address the difference between dogs' preference for chewing (rough texture) and cats' preference for licking (smooth + grooved). If the hardness of the food to be extruded is greater than the expansion capacity of spring 14 and spring 2 18, a plastic film can be tightly placed on the inner surface of the arc frame 6 and the cylinder 8 before extruding the food, and the edges can be clamped by the connection between the lip mold 5 and the mold head 1.This effectively prevents excessive compression of the spherical texture strips 15 and triangular texture strips 19, which can cause them to accumulate in mold cavities 1-12 and 1-2, making them difficult to clean.

[0030] An O-ring 20 is provided between the mold head 1 and the mold lip 5. The O-ring 20 is fixedly connected to the mold lip 5. The O-ring 20 can increase the sealing at the connection between the mold head 1 and the mold lip 5.

[0031] A connecting block 21 is fixedly connected to the side of the mold head 1. A limiting cavity 22 is opened inside the connecting block 21, and a sliding groove 26 is opened on the side of the limiting cavity 22.

[0032] A limiting block 23 is slidably provided inside the limiting cavity 22. One side of the limiting block 23 is fixedly connected to the inner wall of the limiting cavity 22 by a spring 3 24. A insertion block 27 is fixedly connected to the other side of the limiting block 23. The expansion of the spring 3 24 keeps the insertion block 27 in a stable state of insertion with the slot 29.

[0033] An operating rod 25 is fixedly connected to the side of the limiting block 23, and the operating rod 25 matches the slide groove 26.

[0034] A connecting arm 28 is fixedly connected to the side of the mold lip 5. A slot 29 is provided on the side of the connecting arm 28, and the slot 29 matches the insertion block 27.

[0035] The flexible node 4 includes a first support 401 and a second support 402. The first support 401 is detachably connected to the mold head 1 by screws, and the second support 402 is detachably connected to the mold lip 5 by screws. The ends of the first support 401 and the second support 402 are respectively connected to the mold head 1 and the mold lip 5 by screws, which facilitates the subsequent separate removal of the mold lip 5 for the use of the mold head 1 alone, and also facilitates the assembly of the mold lip 5 with other specifications of mold heads 1.

[0036] The working principle of this practical application is as follows:

[0037] The connecting sleeve 2 is used to connect the die head 1 and the extrusion cylinder 3 by thread, which facilitates the replacement of the die head 1. If the surface of the pet food to be extruded is smooth, the connection between the die head 1 and the die lip 5 can be removed. If the surface of the pet food to be extruded has a textured groove, the die head 1 and the die lip 5 are connected. The raised strip 7 and the triangular texture strip 19 set on the inner surface are used to help change the groove pattern on the outer surface of the extruded food. When the cylinder 8 is slid by manually rotating the adjusting column 9, the spherical texture strip 15 and the triangular texture strip 19 hidden in the arc frame 6 are changed, and the style of the groove on the outer surface of the extruded food can be changed.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
