DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0033] Please refer to Figures 1-8 The present application provides a technical solution: embodiment 1

[0034] In the production process of pet food, the proportioning of raw materials generally relies on manual weighing or simple volumetric material taking, which is tedious and labor-intensive, and it is difficult to ensure the accurate consistency of the amount of each component. At the same time, traditional mechanical pushing or spiral extrusion structure is easy to exert uneven pressure on powdery or granular feed raw materials, resulting in local compaction and reduced flowability, which further affects the subsequent mixing uniformity and the bulk density, palatability and digestibility of the final product. The above problems are particularly prominent in the context of multi-raw material collaborative dosing, and there is an urgent need for an automatic quantitative feeding structure that does not require manual intervention, can stably output according to the preset proportion, and avoids deformation of the raw materials throughout the process.

[0035] To this end, the present application proposes:

[0036] The application discloses a feed processing device for pet food production, which comprises a feed component box 1 and a multi-feed processing cylinder 2. The bottom of the multi-feed processing cylinder 2 is connected with an extrusion box 55. After the raw material mixing is completed, the raw material can be conveyed into the extrusion box 55 through a spiral conveying part 20 for extrusion treatment. The top of the feed component box 1 is provided with a feeding pipe 53. The feed component box 1 is provided with a plurality of groups of fixed plates 52 which are uniformly arranged on the top of the multi-feed processing cylinder 2. The fixed plates 52 are arranged between each group of the feed component box 1 and are used for increasing the overall strength. The bottom of each group of the feed component box 1 is provided with a discharging pipe 3. The discharging pipe 3 is connected with the multi-feed processing cylinder 2 through a guide pipe 4. The discharging pipe 3 is provided with a quantitative material taking assembly 5. The quantitative material taking assembly 5 is driven to reciprocate in the discharging pipe 3 through a driving assembly 6. The discharging pipe 3 is further provided with an adjusting assembly 7 which is used for controlling the amount of material taken by the material taking mechanism each time and is used for controlling the amount of material taken by each group of raw material each time so as to realize proportional conveying of the multi-group raw material into the multi-feed processing cylinder 2. The quantitative material taking assembly 5 comprises a material taking column 501 and a bottom plug 502. The material taking column 501 is in a non-cylindrical shape. The top of the material taking column 501 is provided with a material taking cavity 8. The two sides of the material taking column 501 which are located at the lower part of the material taking cavity 8 are symmetrically provided with discharging channels 9. One end of the discharging channel 9 is communicated with the material taking cavity 8 and the other end penetrates through the bottom of the material taking column 501. The bottom plug 502 is arranged in the material taking cavity 8 in a sliding mode and is arranged in sealing fit with the inner wall of the material taking cavity 8. The top of the inner cavity of the feed component box 1 is provided with a sealing frame 10 in a sliding mode. The sealing frame 10 is provided with a piston assembly 11. The material taking column 501 is moved upwards to form a seal with the sealing frame 10 and applies pressure to the material taking cavity 8 through the piston assembly 11 so as to make the bottom plug 502 slide downwards. The raw material is discharged into the multi-feed processing cylinder 2 through the discharging channel 9 after the bottom plug 502 is moved downwards. The material taking column 501 is provided with a reset part which is used for driving the bottom plug 502 to reset. The adjusting assembly 7 is used for adjusting the height position of the bottom plug 502 in each group of the feed component box 1 so as to control the volume of the raw material filled in the material taking cavity 8 after the material taking column 501 is moved upwards each time.

[0037] The embodiment provides a multi-source quantitative material feeding structure based on a gas pressure driving and volume regulation double mechanism. The core of the structure is that raw material metering, closed pressurization and directional discharging are integrated in a single material taking column 501 and its matched assembly. The structure does not rely on external pumping or extrusion power. Only the axial movement of the material taking column 501 triggers the sealing establishment and pressure transmission, realizes the three-stage circulation operation of filling, closed pressurization and directional release. The structure avoids the flow drift caused by frictional resistance in continuous conveying and avoids the breakage or deformation of sensitive raw materials such as puffed particles and freeze-dried meat particles caused by mechanical extrusion. The structure is suitable for the production scenes of pet main food and functional snacks containing high oil, high fiber or heat-sensitive ingredients.

[0038] The discharge pipe 3 is communicated with the multi-material processing cylinder 2 through the guide pipe 4; the discharge pipe 3 is vertically arranged and embedded in the conical part at the bottom of the food material component box 1, and the guide pipe 4 is connected to the upper part of the side wall of the multi-material processing cylinder 2 in an inclined downward manner, so as to ensure that the discharge direction forms a certain angle with the initial material layer in the multi-material processing cylinder 2, and avoid local accumulation caused by vertical impact of the raw materials.

[0039] The quantitative material taking assembly 5 comprises a material taking column 501 and a bottom plug 502; the material taking column 501 is a non-cylindrical body, which can slide without rotating. The bottom plug 502 is a piston body with a triangular top, and is covered with a fluorine rubber sealing layer on the outer periphery, which forms a radial interference fit with the inner wall of the material taking cavity 8 to realize dynamic sealing; the top of the bottom plug 502 is triangular, and can guide the raw materials to flow into the discharge channel 9 after the bottom plug 502 moves downward; the bottom plug 502 is provided with a plug rod 44 at the center of the bottom, which is used for linkage with the subsequent adjusting assembly 7.

[0040] The sealing frame 10 is arranged on the top of the inner cavity of the food material component box 1 and can slide up and down, which cooperates with the base frame 111 and the piston plate 112 to form a closed space with the top of the material taking column 501 during the upward movement of the material taking column 501.

[0041] The adjusting assembly 7 is used for adjusting the height position of the bottom plug 502 in each food material component box 1, so as to control the volume of the raw materials loaded into the material taking cavity 8 after the upward movement of the material taking column 501 according to the proportion of the raw materials taken out from each food material component box 1 at one time; after the material taking cavity 8 takes the materials and is sealed by the sealing frame 10 and the piston plate 112, the piston plate 112 moves downward to increase the pressure of the material taking cavity 8, so as to make the bottom plug 502 move downward to realize the communication between the material taking cavity 8 and the material taking channel, so that the raw materials are discharged to the multi-material processing cylinder 2 through the material taking channel; after the raw materials in the material taking cavity 8 are discharged, the bottom plug 502 is reset to block the material taking channel, and then the material taking column 501 moves downward to take materials again; it should be noted that the height of the materials in the raw material barrel is lower than a certain height of the sealing frame 10.

[0042] The cooperative working process of the above components is as follows: the material taking column 501 moves downward under the driving of the driving assembly 6, at this time, the sealing frame 10 does not contact with the material taking column 501, and the material taking cavity 8 is in an open state, so that the raw materials fall into the cavity under the action of gravity until the cavity is filled to the height of the bottom plug 502; then the material taking column 501 moves upward, the lower inclined surface 29 at the top of the material taking column 501 gradually contacts with the upper inclined surface 30 at the bottom of the sealing frame 10, pushes the sealing frame 10 to move upward synchronously, and the two form a closed cavity; as the sealing frame 10 continues to move upward, the space below the sealing frame 10 is compressed, the air pressure is increased, and the air pressure is introduced into the top of the material taking cavity 8 through the small gap between the sealing frame 10 and the material taking column 501 or a special air path, and acts on the upper surface of the bottom plug 502; after the air pressure difference overcomes the elastic force of the reset member, the bottom plug 502 begins to slide downward, opens the two discharge channels 9, and the raw materials are horizontally discharged through the channels and enter the multi-material processing cylinder 2 through the guide pipe 4.

[0043] By the technical scheme, the application realizes the following: under the premise of not needing manual weighing, the initial height of the bottom plug 502 is set by the adjusting assembly 7 to accurately limit the effective volume of the material taking cavity 8; in combination with the reciprocating movement of the material taking column 501 and the air pressure generating unit composed of the sealing frame 10 and the piston assembly 11, the bottom plug 502 is driven to slide and discharge in a pure air pressure mode, and there is no mechanical extrusion action in the whole process; thus, each group of raw materials can be stably and synchronously conveyed to the multi-material processing cylinder 2 according to the preset volume ratio, and the technical problems of low manual proportioning accuracy and poor efficiency in the background technology, and abnormal compactness of raw materials due to uneven pressure, affecting the taste of finished products, are solved; at the same time, air pressure driven discharge avoids physical damage to fragile components such as puffed particles and fruit and vegetable freeze-dried particles, maintains the original loose form and nutritional integrity of the components, and significantly improves the texture consistency of the final product and the willingness of animals to eat. Specific embodiment 2

[0045] Based on the above-mentioned embodiments, the present embodiment further provides:

[0046] The driving assembly 6 includes a driving rod 601 and a motor 602, the bottom of the discharge pipe 3 extends with a solid rod column 12, the bottom end of the material taking column 501 is provided with a long hole 13 for the insertion of the driving rod 601, the inner wall of the long hole 13 is provided with a reciprocating spiral groove 14, one end of the driving rod 601 inserted into the long hole 13 is provided with a guide rod 15 matched with the reciprocating spiral groove 14, the other end of the driving rod 601 penetrates through the solid rod column 12 and forms a rotary connection with the solid rod column 12, the first tooth disc 16 is arranged on the part of the driving rod 601 extending to the lower part of the solid rod column 12, the outer wall of the multi-material processing cylinder 2 is rotatably provided with an annular tooth disc 17, the outer part of the annular tooth disc 17 is engaged with each first tooth disc 16, the output end of the motor 602 is fixedly provided with a long shaft 18, the long shaft 18 is provided with a second tooth disc 19 engaged with the inner ring of the annular tooth disc 17, wherein, the annular cavity 54 is arranged in the multi-material processing cylinder 2, the lower end of the long shaft 18 extends into the annular cavity 54, the second tooth disc 19 is fixed to the part of the long shaft 18 located in the annular cavity 54, the inner ring of the annular tooth disc 17 is embedded on the inner wall of the multi-material processing cylinder 2, and the multi-material processing cylinder 2 at the annular cavity 54 is provided with a gap for the engagement of the second tooth disc 19 and the annular tooth disc 17.

[0047] The driving assembly 6 provided in the present embodiment synchronously completes the reciprocating movement up and down by the unified driving of the motor 602, solves the technical problems of time sequence misalignment of proportioning, inconsistent feeding rhythm and difficulty in maintaining stable and continuous mixing rhythm caused by independent material taking of each food ingredient box 1.

[0048] The above components work together as follows: after the motor 602 is started, the long shaft 18 drives the second gear plate 19 to rotate, driving the ring gear plate 17 to rotate around its own axis; the outer ring of the ring gear plate 17 synchronously drives all the first gear plates 16 to rotate at the same angular velocity; each first gear plate 16 drives the corresponding drive rod 601 to rotate; when the drive rod 601 rotates, the end guide rod 15 slides along the reciprocating spiral groove 14 in the long hole 13 of the material taking column 501, forcing the material taking column 501 to make strict periodic up-and-down linear motion along the axis direction of the discharge pipe 3; all the material taking columns 501 complete the same displacement at the same time. Specific embodiment 3

[0050] On the basis of the above embodiments, the present embodiment further provides:

[0051] The multi-material processing cylinder 2 is provided with a spiral conveying member 20, the top end of the spiral conveying member 20 extends to the outside of the multi-material processing cylinder 2, one end of the spiral conveying member 20 located outside the multi-material processing cylinder 2 is provided with a third gear plate 21, and the long shaft 18 is provided with a fourth gear plate 22 engaged with the third gear plate 21.

[0052] The technical scheme corresponding to the present embodiment integrates the stirring function in the main drive system, and synchronously drives multiple groups of raw material quantitative material taking and dynamic stirring of materials in the multi-material processing cylinder 2 by a single motor 602 output power. The core lies in that the topology reuse of gear transmission path is utilized, the stirring action and the material taking rhythm are kept mechanically synchronous without adding an independent power source, thereby improving the mixing uniformity, shortening the process cycle, and reducing the structural complexity and energy consumption of the whole machine. It should be noted that, in order to realize the division of raw material taking and stirring in the multi-material processing cylinder 2, and avoid the complicated structure of using multiple motors 602 for driving, the drive rod 601 and the first gear plate 16 are connected through a first one-way peripheral bearing. When the motor 602 rotates forward, the drive rod 601 can be driven to rotate for material taking and feeding. When the output end of the motor 602 reverses, material taking and feeding cannot be performed. The spiral conveying member 20 is used to extrude and convey the mixed materials into the puffing box 55 for puffing treatment. The materials treated by puffing are output through the caliber of the puffing box 55 to form pet feed (the puffing box mainly sprays high-temperature and high-pressure gas into the inside through a gas pump, and then extrudes the materials after puffing to prepare pet feed. The puffing box is a prior art, so it will not be described in detail). In addition, in order to better mix the materials when they are conveyed into the multi-material processing cylinder 2, the spiral blade at the top of the spiral conveying member 20 is provided with a mixing rod 56. When the motor 602 rotates forward, the raw materials in the food material component box 1 are output. At this time, the spiral conveying member 20 cannot convey the materials in the multi-material processing cylinder 2 downward, so that the mixing rod 56 mixes the materials. When the output end of the motor 602 reverses, the spiral conveying member 20 extrudes and pushes the mixed materials downward. Specific embodiment 4

[0054] On the basis of the above-mentioned embodiments, the present embodiment further provides:

[0055] The piston assembly 11 comprises a base frame 111 and a piston plate 112. The base frame 111 is provided with a through slot 25 vertically penetrating the base frame 111. The inner wall of the through slot 25 is provided with a bracket slot 26. The piston plate 112 is vertically slidingly arranged in the bracket slot 26. The inner cavity of the food component box 1 is provided with a push rod 27 at the top. The piston plate 112 is slidingly downward under the pressure of the push rod 27 after the sealing frame 10 is moved upward, so as to increase the internal pressure of the material taking cavity 8. The inner wall of the bottom of the bracket slot 26 is provided with a first reset spring 28 for driving the piston plate 112 to reset.

[0056] The cooperative relationship of each component is as follows: when the material taking column 501 is driven by the driving assembly 6 to move upward, the top lower inclined surface 29 of the material taking column 501 is in contact with the upper inclined surface 30 of the bottom of the sealing frame 10, so as to push the sealing frame 10 to move upward synchronously. In the process of the upward movement of the sealing frame 10, the piston plate 112 enters the action area of the push rod 27. The push rod 27 applies a downward constraint reaction force to the piston plate 112, so as to force the piston plate 112 to slide downward along the bracket slot 26 against the pre-tightening force of the first reset spring 28. The piston plate 112 moves downward to compress the space of the material taking cavity 8. The gas is quickly filled into the top area of the material taking cavity 8 through the through slot 25, so as to form a uniform positive pressure under the condition of airtightness. The positive pressure acts on the upper surface of the bottom plug 502, so as to drive the bottom plug 502 to slide downward along the inner wall of the material taking cavity 8, open the discharge channel 9, and make the raw material be discharged from the material taking cavity 8 to the multi-material processing cylinder 2 through the two side discharge channels 9. Specific embodiment 5

[0059] The top end surface of the material taking column 501 is provided with a lower inclined surface 29. The bottom of the sealing frame 10 is provided with an upper inclined surface 30 matched with the lower inclined surface 29. The upper inclined surface 30 is arranged at the top of the material taking column 501, so that the raw material is not accumulated on the top end surface of the material taking column 501 after the material taking column 501 is moved upward to take the material.

[0060] Through the above technical solution, the sealing space between the sealing frame 10 and the material taking column 501 is better after the two are in contact. The contact surface between the upper inclined surface 30 and the lower inclined surface 29 can be provided with a sealing rubber layer, so as to improve the sealing effect after the contact.

[0064] The embodiment surrounds the vertical guiding stability between the sealing frame 10 and the food material component box 1, and is limited by the nesting structure cooperation of the frame type seat 31-frame type groove 32, and is supplemented by the first booster spring 35 to provide axial pre-tightening force, thereby constructing a kind of high-precision guiding.

[0065] Through the above technical scheme, the following is realized: in the instant of starting uplink of the material taking column 501, the sealing frame 10 immediately follows the response, and forms initial sealing contact with the lower inclined surface 29 at the top of the material taking column 501 without delay; since there is a certain geometric constraint relationship between the frame type groove 32 and the frame type seat 31, the sealing frame 10 always keeps axis vertical in the whole uplink process, avoiding local air leakage or pressure leakage caused by inclination; the pre-tightening force provided by the first booster spring 35 makes the contact surface of the sealing frame 10 with the material taking column 501 have basic positive pressure before pressurization, which significantly improves the air-tightness establishment speed and pressure transmission efficiency in the subsequent pressurization stage of the piston assembly 11. Specific embodiment 7

[0067] On the basis of the above embodiment, the embodiment further provides:

[0068] The horizontal slot 36 is horizontally provided on the sealing frame 10, wherein the bottom inner wall of the horizontal slot 36 is flush with the top of the opening of the material taking cavity 8 after the upper inclined surface and the lower inclined surface are attached, the base frame 111 is horizontally slidably arranged in the horizontal slot 36, the limit hinge block 37 is arranged on one side of the top of the base frame 111, the hinge rod 38 is hingedly arranged on the limit hinge block 37, one end of the hinge rod 38 away from the limit hinge block 37 is hingedly arranged on the top of the inner cavity of the raw material barrel, the hinge rod 38 includes the first hinge rod 381 and the second hinge rod 382, the rod slot 39 is arranged in the first hinge rod 381 for inserting the second hinge rod 382, and the second booster spring 40 is arranged in the rod slot 39.

[0069] The embodiment realizes the controllable transverse displacement and buffer reset of the base frame 111 in the lifting process of the sealing frame 10 by arranging the horizontal slot 36 on the sealing frame 10 and making the base frame 111 horizontally slide along the slot, cooperating with the structure of the hinge rod 38 and the built-in elastic element, thereby performing scraping work on the surface of the raw material above the material taking column 501 after the material taking column 501 takes the material, and ensuring that the volume of the raw material in the material taking cavity 8 is stable, without stacking or vacancy each time.

[0070] The articulated rod 38 is a two-section telescopic linkage. When the sealing frame 10 moves upward along with the material taking column 501, the bottom upper inclined surface 30 of the sealing frame 10 abuts against the top lower inclined surface 29 of the material taking column 501 and pushes the sealing frame 10 to move upward synchronously. During the upward movement of the sealing frame 10, the first articulated rod 381 is compressed and displaced to the side of the second articulated rod 382, so that the base frame 111 keeps moving straight upward, and the push rod 27 pushes the piston plate 112 to move downward smoothly. Specific embodiment 8

[0072] Based on the above-mentioned embodiments, the present embodiment further provides:

[0073] The adjusting assembly 7 comprises an adjusting block 701. The material taking column 501 located below the material taking cavity 8 is provided with a block groove 41 in which the adjusting block 701 slides up and down. The adjusting block 701 further comprises an adjusting rod 702. The adjusting rod 702 penetrates through the material taking column 501 and is in threaded connection with the driving rod 601 and the material taking column 501. The adjusting rod 702 is in axial sliding connection with the driving rod 601. The reset member comprises a second reset spring 43. The adjusting block 701 is provided with an adjusting groove 42. The bottom plug 502 is provided with an insertion rod 44. The bottom end of the insertion rod 44 is inserted into the block groove 41 and extends into the adjusting groove 42. The second reset spring 43 is fixed in the adjusting groove 42 and continuously abuts against the bottom end of the insertion rod 44. One end of the insertion rod 44 located in the adjusting groove 42 is provided with a side block 45. The sidewall of the adjusting groove 42 is provided with a side groove 46 in which the side block 45 slides.

[0074] The cooperative relationship of each component is as follows: when the operator rotates the adjusting rod 702 (the bottom of the adjusting rod 702 is provided with a rotating wheel, which facilitates the rotation of the adjusting rod 702. The adjusting rod 702 can be provided with scales. According to the amount of material in each material taking column 501, the adjusting rod 702 is rotated to the corresponding scale position), the outer thread of the adjusting rod 702 moves relative to the inner thread of the material taking column 501, and the adjusting block 701 is pushed to ascend or descend along the block groove 41; the displacement of the adjusting block 701 drives the height position of the bottom plug 502 in the material taking cavity 8, so as to control the space of material in the material taking cavity 8 each time; since the bottom end of the insertion rod 44 is always abutted by the second reset spring 43, and the top end of the insertion rod 44 is fixedly connected to the bottom plug 502, the ascending and descending of the adjusting block 701 will forcibly drive the bottom plug 502 to ascend and descend synchronously, so as to set the initial height of the bottom plug 502 in the material taking cavity 8; the sliding of the side block 45 in the side groove 46 is under the action of the second reset spring 43. The side block 45 is always located at the top of the side groove 46. After the space between the material taking cavity 8 and the piston plate 112 is compressed by the piston plate 112 each time, the bottom plug 502 drives the insertion rod 44 to compress the second reset spring 43.

[0075] By the technical scheme, the operator can only rotate the adjusting rod 702 to make the adjusting block 701 accurately ascend and descend along the block groove 41, and then drive the bottom plug 502 to be adjusted to a preset initial height in the material taking cavity 8 when the device is in a stationary state; when the material taking column 501 moves upward with the driving assembly 6 and forms a sealed cavity with the sealing frame 10, the piston assembly 11 exerts pressure to make the bottom plug 502 move downward against the elastic force of the second return spring 43, and the raw material is discharged through the discharge passage 9; after the discharge is completed, the material taking column 501 moves downward, and the second return spring 43 immediately pushes the bottom plug 502 back to the preset height, thereby completing a quantitative material taking cycle.

[0080] The first one-way valve 49 on the outer wall of the expansion cavity 47 only allows gas to be discharged outward, which means that when the expansion plate 48 moves upward, the space above the expansion cavity 47 is pressurized to a certain pressure, and the gas will be discharged from the first one-way valve 49

[0081] The second one-way valve 50 is arranged on the expansion plate 48, the third one-way valve 51 is arranged below the expansion plate 48, when the expansion plate 48 moves upward, the space below the expansion cavity 47 will realize air suction through the third one-way valve 51, and when the expansion plate 48 moves downward, the air below the expansion cavity 47 will be discharged to the upper side of the expansion plate 48 through the second one-way valve 50.
