Description

Technical Field

[0001] This utility model relates to the field of pet food technology, and in particular to a pet food extruder that is easy to clean. Background Technology

[0002] Pet food is a specially formulated food that provides nutrition and energy for pets. It is usually divided into various types such as dog food and cat food. In recent years, with the rapid development of the pet industry, the variety and demand for pet food have been increasing. Extruded pet food is favored by many pet owners because of its good taste and high digestibility. The extrusion process can not only improve the nutritional value of food, but also extend its shelf life. However, the extruder needs to be cleaned frequently after use. Therefore, there is a need for a pet food extruder that is easy to clean.

[0003] Traditional pet food extruders produce a large amount of residue and grease during the extrusion process. These substances usually adhere to the internal structure of the equipment. Due to the often complex design of extruders, the inaccessible internal areas make cleaning extremely difficult. These residues not only affect the performance of the equipment but may also pose hygiene hazards, increasing the risk of cross-contamination and thus affecting the safety and quality of pet food. Moreover, the internal structure of traditional extruders is usually fixed by bolts and nuts. When it is necessary to disassemble and clean the internal parts, the operator needs to loosen multiple bolts and nuts one by one, and then tighten them again after cleaning, which is time-consuming and reduces work efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pet food extruder that is easy to clean.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pet food extruder that is easy to clean includes an extruder body, a heating element fixed to the outer wall of the extruder body, a cover plate on the top of the extruder body, and multiple first fixing mechanisms for fixing the cover plate arranged linearly at equal intervals on the outer wall of the extruder body. A feed hopper is fixed near the edge of the top of the cover plate. An annular plate is fixed to the inner wall of the extruder body, and a circular plate is provided on top of the annular plate. A lifting mechanism for raising and lowering the circular plate is provided at the bottom of the extruder body. A second fixing mechanism for fixing the circular plate is provided on top of the annular plate. A connecting rod is provided on top of the circular plate, and a locking mechanism for engaging the connecting rod is provided on top of the circular plate. A rotating mechanism for rotating the connecting rod is provided at the bottom of the cover plate. The side wall of the connecting rod is sleeved with... The device includes a sleeve with a limiting mechanism on its inner wall for restricting the sleeve. Multiple stirring rods are fixed in a circular pattern at equal intervals on the outer wall of the sleeve, arranged in three groups. Three first arc-shaped scrapers are also arranged in a circular pattern at equal intervals on the inner wall of the extruder body, and each of the three first arc-shaped scrapers is fixed to one of the three groups of stirring rods. Three second arc-shaped scrapers are also fixed in a circular pattern at equal intervals on the outer wall of the sleeve, and all three second arc-shaped scrapers are located below the three first arc-shaped scrapers. During use, by releasing the fixing mechanisms on the cover plate, the connecting rods, sleeve, stirring rods, first arc-shaped scrapers, second arc-shaped scrapers, and circular plate inside the extruder body can be easily removed without disassembling a large number of bolts and nuts. This simplifies operation, saves time, and improves work efficiency.

[0007] Preferably, the first fixing mechanism includes an L-shaped plate, which is rotatably connected to the outer wall of the extruder body. A circular groove is formed at the top of the L-shaped plate, and the groove has a constricted opening. A circular slider is slidably connected to the inner wall of the circular groove. A column is fixed to the bottom of the circular slider, and a pull rod is fixed to the top of the circular slider, extending through the top of the L-shaped plate. A spring is installed inside the circular groove and sleeved on the side wall of the pull rod. A circular groove is formed at the top of the cover plate, and the groove is adapted to the column. When the cover plate is removed from the top of the extruder body, multiple second protrusions are removed from multiple second grooves, thus releasing the restriction on the connecting rod and sleeve. The connecting rod and sleeve can be removed from the extruder body as a whole without disassembling a large number of bolts and nuts, simplifying operation, saving time, and improving work efficiency.

[0008] Preferably, the locking mechanism includes a rectangular block, which is rotatably connected to the top center of the circular plate. The bottom end of the connecting rod has a rectangular groove that is adapted to the rectangular block. Through the action of the rectangular block and the rectangular groove, the bottom of the connecting rod can be locked to prevent the connecting rod from moving during rotation and affecting its use.

[0009] Preferably, the rotating mechanism includes a rotating shaft that passes through the middle of the top of the cover plate. A motor is fixed to the top of the cover plate, and the output shaft of the motor is fixed to the rotating shaft. A disc is fixed to the bottom of the rotating shaft. Multiple second protrusions are fixed in a circular pattern at equal intervals on the bottom of the disc. Multiple second grooves are equally spaced on the top of the connecting rod, and each of the second grooves is adapted to a multiple second protrusion. The limiting mechanism includes multiple first protrusions that are equally spaced in a circular pattern and fixed to the side wall of the connecting rod. Multiple first grooves are formed on the inner side wall of the sleeve. The grooves are adapted to multiple first protrusions. The second fixing mechanism includes multiple limiting rods, which are evenly spaced and circularly fixed to the bottom of the circular plate. The top of the annular plate has multiple limiting holes, which correspond one-to-one with the multiple limiting rods. The drive motor drives the rotating shaft to rotate, which in turn drives the connecting rod to rotate in conjunction with the disc, rectangular block, multiple second protrusions, and multiple second grooves. The rotation of the connecting rod, in conjunction with the multiple first protrusions and multiple first grooves, drives the sleeve to rotate, which in turn drives the multiple stirring rods to rotate, thus stirring the pet food and making it puffed more evenly.

[0010] Preferably, the lifting mechanism includes a second protrusion, which is disposed inside the body of the extruder and located below the circular plate. Four electric telescopic rods are fixed at the bottom of the body of the extruder, and the output ends of the four electric telescopic rods are respectively fixed at the four corners of the bottom of the second protrusion. Simultaneously, the four electric telescopic rods are driven to move the second protrusion upward, thereby moving the circular plate upward, so that the multiple limiting rods disengage from the multiple limiting holes until the circular plate is pushed out of the body of the extruder, which facilitates the cleaning of the circular plate.

[0011] Preferably, the outer wall of the puffing machine body has a discharge port, which is located below the heating component. The lower edge of the discharge port is flush with the top of the circular plate. An arc-shaped door is rotatably connected to the outer wall of the puffing machine body near the discharge port, and the arc-shaped door is adapted to the discharge port. Rotating the arc-shaped door opens the discharge port. At this time, as the sleeve rotates, it drives multiple second arc-shaped scrapers to rotate, which can scrape the puffed pet food out of the puffing machine body through the discharge port for collection and processing.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. During use, by releasing the fixing of the cover plate by multiple first fixing mechanisms, the connecting rod, sleeve, stirring rod, first arc scraper, second arc scraper and circular plate inside the extruder body can be easily removed without disassembling a large number of bolts and nuts. The operation is simple, saves time and improves work efficiency.

[0014] 2. Through the second fixing mechanism, rotating mechanism, limiting mechanism, snap-fit ​​mechanism, and lifting mechanism, the connecting rod, sleeve, stirring rod, first arc scraper, second arc scraper, and circular plate can be modularly processed, making it convenient to clean them one by one, ensuring the hygiene of the equipment and reducing the risk of cross-contamination.

[0028] In this utility model, the rotating mechanism includes a rotating shaft 14, which passes through the middle of the top of the cover plate 2. A motor 7 is fixed to the top of the cover plate 2, and the output shaft of the motor 7 is fixed to the rotating shaft 14. A disc 15 is fixed to the bottom of the rotating shaft 14. A plurality of second protrusions 27 are fixed at equal intervals in a circular pattern on the bottom of the disc 15.

The limiting mechanism includes a plurality of first protrusions 25, which are equally spaced in a circular pattern and fixed to the side wall of the connecting rod 19. A plurality of first grooves 24 are opened on the inner side wall of the sleeve 20, and the plurality of first grooves 24 are respectively adapted to the first protrusions 27. Multiple first protrusions 25 are adapted, and the second fixing mechanism includes multiple limiting rods 28. The multiple limiting rods 28 are evenly spaced and circularly fixed to the bottom of the circular plate 16. Multiple limiting holes 29 are opened on the top of the annular plate 17, and the multiple limiting holes 29 correspond one-to-one with the multiple limiting rods 28. The drive motor 7 drives the rotating shaft 14 to rotate, which, together with the disc 15, the rectangular block 30, the multiple second protrusions 27 and the multiple second grooves 26, drives the connecting rod 19 to rotate. The rotation of the connecting rod 19, together with the multiple first protrusions 25 and the multiple first grooves 24, drives the sleeve 20 to rotate, which in turn drives the multiple stirring rods 21 to rotate, so as to stir the pet food and make it puffed more evenly.

[0029] In this utility model, the lifting mechanism includes a second protrusion 27, which is disposed inside the extruder body 1 and located below the circular plate 16. Four electric telescopic rods 18 are fixed at the bottom of the extruder body 1, and the output ends of the four electric telescopic rods 18 are respectively fixed at the four corners of the bottom of the second protrusion 27. At the same time, the four electric telescopic rods 18 are driven to move the second protrusion 27 upward, thereby moving the circular plate 16 upward, so that the multiple limiting rods 28 are disengaged from the multiple limiting holes 29 until the circular plate 16 is pushed out of the extruder body 1, which facilitates the cleaning of the circular plate 16.

[0030] In this invention, the outer wall of the puffing machine body 1 is provided with a discharge port 3, and the discharge port 3 is located below the heating component 32. The lower edge of the discharge port 3 is flush with the top of the circular plate 16. An arc-shaped door 4 is rotatably connected to the outer wall of the puffing machine body 1 near the discharge port 3, and the arc-shaped door 4 is adapted to the discharge port 3. Rotating the arc-shaped door 4 makes the discharge port 3 open. At this time, as the sleeve 20 rotates, it drives multiple second arc-shaped scrapers 23 to rotate, which can scrape the puffed pet food out of the puffing machine body 1 through the discharge port 3 for collection and processing.

[0031] Working Principle: During operation, pet food is fed into the extruder body 1 through the feed hopper 6. The heating element 32 then extrudes the food. During extrusion, the power switch of the motor 7 is turned on, driving the motor 7 to rotate the shaft 14. This, in conjunction with the disc 15, rectangular block 30, multiple second protrusions 27, and multiple second grooves 26, rotates the connecting rod 19. The rotation of the connecting rod 19, in turn, in conjunction with the multiple first protrusions 25 and multiple first grooves 24, rotates the sleeve 20, which in turn rotates the multiple stirring rods 21, thus stirring and extruding the pet food. To achieve more uniform mixing, during the mixing process, the three first arc-shaped scrapers 22 rotate along the inner wall of the extruder body 1, scraping and cleaning the inner wall of the extruder body 1 to prevent pet food from sticking to the inner wall of the extruder body 1. After extrusion, the arc-shaped door 4 is rotated to open the discharge port 3. At this time, as the sleeve 20 rotates, it drives multiple second arc-shaped scrapers 23 to rotate, which can scrape the extruded pet food out of the extruder body 1 through the discharge port 3 for collection and processing. When it is necessary to clean the various parts inside the extruder body 1, multiple levers are pulled first. 12. This causes multiple circular sliders 9 to move upwards along the inner walls of multiple circular grooves 8 until multiple columns 10 disengage from and retract into the multiple circular grooves 8 one by one. At this point, multiple L-shaped plates 5 are rotated so that they disengage from the top of the cover plate 2. The cover plate 2 can then be removed from the top of the extruder body 1. The sleeve 20 can then be pulled out from the side wall of the connecting rod 19. The sleeve 20, multiple stirring rods 21, three first arc-shaped scrapers 22, and three second arc-shaped scrapers 23 can then be removed from the extruder body 1 as a whole. The connecting rod 19 is removed from the body 1 of the extruder. At this time, the rectangular block 30 and the rectangular groove 31 are in a disengaged state. When the power switch of the four electric telescopic rods 18 is turned on, the four electric telescopic rods 18 are driven to move the second protrusion 27 upward, which in turn moves the circular plate 16 upward, so that the multiple limiting rods 28 are disengaged from the multiple limiting holes 29, until the circular plate 16 is pushed out of the body 1 of the extruder. This allows for modular processing of the extruder, making it easy to clean without having to disassemble a large number of bolts and nuts, saving time and improving work efficiency.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
