Description

Technical Field

[0001] This invention relates to the technical field of cat food processing, and in particular to a cold-pressed raw bone and meat cat food processing technology and equipment. Background Technology

[0002] Cat food is now typically manufactured using extrusion or cold pressing processes, with cold pressing in particular preserving more nutrients and making it more palatable.

[0003] Chinese utility model patent CN221532811U discloses a cold-pressing forming device for baked grains. The device includes an operating table, a pressing frame mounted on the upper surface of the operating table, a lifting mechanism mounted on the pressing frame, a lifting frame internally connected to the pressing frame, and the pressing mechanism mounted on the lifting frame. A clamping mechanism is mounted on the operating table, and a placement mechanism is mounted on the placement frame. A pushing mechanism is connected to one side of the pressing frame. This utility model's cold-pressing forming device for baked grains involves starting an adjusting motor, which drives a rack to move, causing a clamping plate to slide on a slide rail, thus fixing the raw material tray to be baked. Starting a lifting motor causes a threaded rod to rotate on a threaded sleeve, which in turn moves the lifting frame up and down. After cold pressing, an electric push rod drives a push plate to move the raw material tray of baked grains, which is then pushed to the placement frame through the discharge port. An electric push rod then drives a second electric push rod to move the lifting plate, facilitating the placement of the raw material tray.

[0004] The aforementioned equipment is only set up with a single workstation, and the feeding, cold pressing, discharging and unloading operations are completed at one workstation, resulting in low work efficiency. Summary of the Invention

[0019] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0020] A cold-pressed raw bone and meat cat food processing technology includes: S1. After adjusting the moisture content of the cat food raw material to the standard value, it is fed into the extruder. The extruder runs and fills the multiple forming cavities of the lower die located on the upper material position of the turntable with the cat food raw material. S2. The turntable moves forward, causing the lower mold filled with cat food ingredients to move to the forming position. At the forming position, the cat food ingredients are cold-pressed and then solidified by heating. S3, the turntable steps forward, causing the formed cat food to be discharged from the lower mold at the discharge position; S4.

S6. The turntable moves one step at a time, repeating the above steps.

[0021] Example 1, as Figures 1 to 4 , Figure 11As shown, a cold-pressed raw bone and meat cat food processing equipment includes a base plate 1, an extruder 2 mounted on the base plate 1 via a frame, and a feed hopper 3 on the extruder 2; the extruder 2 is vertically arranged with a discharge port at its bottom, a mold 4 installed in the discharge port, and a turntable 5 horizontally rotatably mounted on the base plate 1, positioned below the extruder 2. The turntable 5 has a feed position, a forming position, a discharge position, a unloading position, and a pre-treatment position arranged sequentially around its circumference. The feed position is located below the discharge port of the extruder 2. A scraper 34 is installed on the outer wall of the discharge port and is located between the feeding position and the forming position. The scraper 34 scrapes the upper surface of the turntable 5. Multiple lower molds 6 are evenly installed on the circumference of the turntable 5 and the multiple lower molds 6 correspond to the feeding position, forming position, discharge position, unloading position and pre-treatment position respectively. The multiple lower molds 6 are provided with multiple forming cavities and are respectively aligned with the upper mold 4. The heater 7 is installed on the base plate 1 through the bracket and is used to heat the lower molds 6 on the forming position.

[0022] Furthermore, the multiple forming cavities of the multiple lower molds 6 are all vertically connected. The discharge position and unloading position of the turntable 5 are integrated. The lower support plate 8 is mounted on the base plate 1 through a bracket and is located below the pre-processing position, feeding position and forming position of the turntable 5. The lower support plate 8 slides in contact with the lower surface of the turntable 5. The push cylinder 9 is mounted on the base plate 1 through a bracket and the telescopic end of the push cylinder 9 is equipped with an upper pressure plate 10. Multiple upper pressure blocks 11 are installed on the lower end face of the upper pressure plate 10 and the multiple upper pressure blocks 11 are respectively aligned with the multiple forming cavities of the lower molds 6 located in the forming position.

[0023] Furthermore, an upper push plate 12 is installed on the telescopic end of the push cylinder 9. Multiple upper push blocks 13 are installed on the lower end face of the upper push plate 12, and the multiple upper push blocks 13 are located above the integrated station of the discharge position and the unloading position of the turntable 5. The length of the multiple upper push blocks 13 is greater than the length of the multiple upper pressure blocks 11, and the multiple upper push blocks 13 are respectively aligned with the multiple forming cavities of the lower mold 6.

[0024] Furthermore, the auxiliary material box 14 is mounted on the base plate 1 via a bracket and is located above the pre-processing station of the turntable 5. The auxiliary material box 14 has a storage chamber inside and a long slot at the bottom. The feeding roller 15 is rotatably mounted on the bracket of the auxiliary material box 14 and its upper sidewall slides in contact with the long slot of the auxiliary material box 14. Multiple material picking holes are evenly arranged on the outer wall of the feeding roller 15 and are respectively aligned with the multiple forming cavities in the row of the lower mold 6. The stepper motor 16 is mounted on the bracket of the auxiliary material box 14 and its output shaft is connected to the feeding roller 15 for transmission.

[0025] Furthermore, the smart camera 17 is mounted on the auxiliary material box 14 via a bracket and faces the turntable 5.

[0026] It is important to understand that the turntable 5 is mounted on the base plate 1 via a cam divider. The cam divider drives the turntable 5 to rotate stepwise. Cat food ingredients are fed into the extruder 2 through the feed hopper 3. The extruder 2 conveys the cat food ingredients downwards. After being shaped by the upper die 4, the cat food ingredients are fed into multiple forming cavities of the lower die 6 at the feed position on the turntable 5. Once the multiple forming cavities are full, the turntable 5 further drives the lower die 6 to the forming position. During this process, the scraper 34 scrapes the upper surface of the turntable 5 to flatten the excess cat food ingredients on the lower die 6. At the forming position, the upper and lower dies... Cat food raw materials in multiple molding cavities of mold 6 are cold-pressed. Heater 7 operates to heat, cook, and dry the cold-pressed cat food, making the cat food molding more stable. Turntable 5 further drives the lower mold 6 to the discharge position. At the discharge position, the cat food in the multiple molding cavities of the upper and lower mold 6 is discharged from the lower mold 6. Turntable 5 further drives the lower mold 6 to the unloading position. At the unloading position, the cat food is discharged from the turntable 5 for collection. Turntable 5 further drives the lower mold 6 to the pre-treatment position. At the pre-treatment position, the lower mold 6 is pre-treated to prepare for the next cold-pressed cat food molding.

[0027] Specifically, the lower support plate 8 closes the bottom of the lower mold 6 located at the feeding position, allowing the cat food raw material conveyed by the upper mold 4 to fill multiple forming cavities of the lower mold 6. When the lower mold 6 reaches the forming position, the push cylinder 9 operates, causing the telescopic end to push the upper pressure block 11 downward through the upper pressure plate 10. This causes multiple upper pressure blocks 11 to extend into multiple forming cavities of the lower mold 6 respectively, and cooperate with the lower support plate 8 to cold press the cat food raw material in the forming cavities. After the cat food is cold-pressed, the telescopic end of the push cylinder 9 drives the upper pressure plate 10 and multiple upper pressure blocks 11 to extend into multiple forming cavities of the lower mold 6 respectively. The lifting of the pressing block 11 causes multiple upper pressing blocks 11 to detach from the lower mold 6; the length of the upper push block 13 is greater than the forming cavity depth of the lower mold 6. When the telescopic end of the push cylinder 9 pushes the upper pressing plate 10 and multiple upper pressing blocks 11 to move downward to cold press the cat food raw material, the telescopic end of the push cylinder 9 pushes the upper push plate 12 and multiple upper push blocks 13 to descend, causing multiple upper push blocks 13 to extend into multiple forming cavities of the lower mold 6 below them, and push the formed cat food downward out of the turntable 5 and the lower mold 6 to complete the cat food discharge and feeding.

[0028] The auxiliary material box 14 stores capsules or pills with specific functions. When the lower mold 6 reaches the pre-processing station, the stepper motor 16 drives the feeding roller 15 to rotate. When the feeding roller 15 rotates, it takes out the capsules or pills from the auxiliary material box 14 through multiple feeding holes and puts them into multiple forming cavities on the lower mold 6. The lower support plate 8 holds the capsules and pills, so that the cold-pressed cat food pellets have the corresponding functions. The smart camera 17 detects the position of multiple rows of forming cavities on the lower mold 6 through visual recognition technology. When the forming cavity passes the smart camera 17, the smart camera 17 sends a signal to the controller of the stepper motor 16. After receiving the signal, the controller controls the stepper motor 16 to run step by step. The stepper motor 16 drives the feeding roller 15 to rotate at a certain angle so that the multiple feeding holes of the feeding roller 15 pass through the long slot of the auxiliary material box 14 and reach above a row of forming holes in the lower mold 6, so that the capsules or pills are accurately put into multiple forming cavities of the lower mold 6.

[0029] As a preferred option, the sealing cover of the auxiliary material box 14 is equipped with a quick-release structure to facilitate the replenishment of capsules or pills, and the feeding hole of the feeding roller 15 can be replaced with different hole diameters to accommodate particles of different sizes; as an alternative option, the feeding method of the auxiliary material box 14 can also adopt a vibrating feeder in conjunction with a quantitative dispensing mechanism to achieve a more uniform feeding effect.

[0030] In addition, for exposed moving parts such as the rotating bearing of turntable 5 and the rotating shaft of feeding roller 15, this embodiment has a protective cover plate (not shown in the figure) under the base plate 1 and a dustproof sealing ring at the rotating bearing of turntable 5 to prevent powder and debris from entering; the sliding contact surfaces of relatively moving parts such as mold 6 and lower support plate 8 are coated with food-grade grease to reduce friction and prevent wear; high-wear parts such as mold 6 and upper mold 4 are made of wear-resistant alloy steel and have a hardened coating on the surface to extend service life; during long-term operation, the heat generated by heater 7 and push cylinder 9 is dissipated through the heat dissipation fins of base plate 1; electrical components such as stepper motor 16, solenoid valve of push cylinder 9 and controller of smart camera 17 are all encapsulated in a waterproof and dustproof control box (not shown in the figure), with a protection level of not less than IP55 to adapt to the humid conditions of food processing environment.

[0031] Compared with the prior art, this embodiment sets up multiple lower molds 6 on the turntable 5 and integrates multiple workstations to realize continuous cold pressing and forming of cat food, which has high work efficiency. Moreover, through the coordinated action of scraper, lower support plate and push cylinder, the precise connection of feeding, forming and discharging processes is ensured, and the degree of integration is high.

[0032] Example 2, as Figures 5 to 9 , Figure 11As shown, a cold-pressed raw bone and meat cat food processing equipment includes a base plate 1, an extruder 2 mounted on the base plate 1 via a frame, and a feed hopper 3 on the extruder 2; the extruder 2 is vertically arranged with a discharge port at its bottom, a mold 4 installed in the discharge port, and a turntable 5 horizontally rotatably mounted on the base plate 1, positioned below the extruder 2. The turntable 5 has a feed position, a forming position, a discharge position, a unloading position, and a pre-treatment position arranged sequentially around its circumference. The feed position is located below the discharge port of the extruder 2. A scraper 34 is installed on the outer wall of the discharge port and is located between the feeding position and the forming position. The scraper 34 scrapes the upper surface of the turntable 5. Multiple lower molds 6 are evenly installed on the circumference of the turntable 5 and the multiple lower molds 6 correspond to the feeding position, forming position, discharge position, unloading position and pre-treatment position respectively. The multiple lower molds 6 are provided with multiple forming cavities and are respectively aligned with the upper mold 4. The heater 7 is installed on the base plate 1 through the bracket and is used to heat the lower molds 6 on the forming position.

[0033] Furthermore, the multiple forming cavities of the multiple lower molds 6 are all vertically connected. The feeding position of the turntable 5 is used for cold pressing and forming cat food. The heater 7 is located above the forming position of the turntable 5. The lower molds 6 are all provided with lower templates 18. The lower templates 18 are elastically installed at the bottom of the turntable 5 by multiple springs 19. Multiple top blocks 20 are installed on the lower templates 18 and are slidably inserted into the forming cavities of the multiple lower molds 6. The upper end face of the multiple top blocks 20 is flush with the upper end face of the lower molds 6. Multiple locking components are installed at the bottom of the turntable 5. When the cat food fills the multiple forming cavities of the lower molds 6, the locking components limit and lock the lower templates 18. The guide plate 25 is installed on the base plate 1 by a bracket and scrapes the upper surface of the turntable 5. The guide plate 25 is located between the discharge position and the pre-processing position of the turntable 5 to form the unloading position.

[0034] The locking assembly includes a socket 21 vertically mounted on the lower end face of the turntable 5, a limit pin 22 horizontally inserted into the horizontal slot of the socket 21, a guide slope is provided on the upper edge of the end of the limit pin 22 facing the lower template 18 and the guide slope is located below the edge of the lower template 18, and an electromagnetic push rod 23 is mounted on the socket 21 and the piston rod of the electromagnetic push rod 23 is connected to the limit pin 22 through a spring 24.

[0035] Furthermore, the nozzle 26 is mounted on the base plate 1 via a bracket and is located above the pretreatment position of the turntable 5. The input end of the nozzle 26 is connected to the output end of the delivery pipe 27.

[0036] It is important to understand that the elastic force of spring 19 is slightly greater than the pressure of cold-pressing the cat food, and the extrusion force of extruder 2 is greater than the pressure of cold-pressing the cat food. When the lower mold 6 reaches below extruder 2, extruder 2 extrudes the cat food raw material through the upper mold 4 into the multiple forming cavities of the lower mold 6. The cat food raw material pushes the multiple top blocks 20 and the lower template 18 downwards, filling the multiple forming cavities of the lower mold 6. At this time, the multiple springs 19 are stretched and stored, and the lower template 18 is locked by the locking component. Because the cat food raw material is subjected to force during filling... The pressure is greater than the cold pressing pressure, so the cat food is cold pressed into shape. The turntable 5 steps further pushes the lower mold 6 to the forming position. The heater 7 runs to heat the lower mold 6 and cook and solidify the formed cat food. When the lower mold 6 reaches the discharge position, the locking component unlocks the lower template 18. The elastic force of the spring 19 is released, pushing the lower template 18 and multiple top blocks 20 upwards, causing the multiple top blocks 20 to push the formed cat food upwards out of the lower mold 6. The turntable 5 steps further guide the formed cat food on the turntable 5 to be pushed out of the turntable 5 to complete the unloading.

[0037] Specifically, when the cat food raw material fills the multiple forming cavities of the lower mold 6, the cat food raw material squeezes and pushes multiple top blocks 20 downwards. The multiple top blocks 20 drive the lower template 18 downwards and stretch and store the force of multiple springs 19. When the lower edge of the lower template 18 contacts the guide slope of the limiting pin 22, it pushes the limiting pin 22 outwards. The limiting pin 22 stretches and stores the force of spring 24. When the multiple forming cavities of the lower mold 6 are filled and cold-pressed, the lower template 18 passes the limiting pin 22. The elastic force of spring 24 is released, pushing the limiting pin 22 inwards so that the inner end of the limiting pin 22 limits and blocks the lower template 18. When the lower mold 6 reaches the discharge position, the piston rod of the electromagnetic push rod 23 extends and pushes the limiting pin 22 outwards after compressing the spring 24, so that the limiting pin 22 is separated from the lower template 18. At this time, the elastic force of spring 19 is released, causing the lower template 18 to rise and reset. The piston rod of the electromagnetic push rod 23 retracts and resets.

[0038] The delivery pipe 27 is connected to an external functional liquid system. When the lower mold 6 reaches below the nozzle 26, the functional liquid is input into the nozzle 26 through the delivery pipe 27 and sprayed downwards to coat the lower mold 6 and multiple top blocks 20 with the functional liquid, thereby coating the surface of the cat food raw material with the functional liquid to improve the functionality of the cat food pellets.

[0039] As an alternative, the spring force coefficient of spring 19 can be adjusted according to the hardness of the cat food raw materials and the molding pressure to meet different formula requirements; the locking component can also be replaced with a pneumatic pin or magnetic locking mechanism to achieve faster locking and unlocking; in addition, the sliding mating surface between the lower template 18 and the turntable 5 is provided with a wear-resistant bushing and filled with food-grade grease to reduce long-term wear; spring 19 and spring 24 are made of stainless steel and coated with an anti-rust coating to ensure elastic stability in humid environments.

[0040] Compared with the prior art, this embodiment uses the extrusion force of the extruder to cold-press the cat food, eliminating the need for an additional molding press and simplifying the equipment structure. At the same time, the automatic cooperation of the spring and locking components realizes the cyclic action of molding, heating, and demolding, which has a high degree of intelligence. Furthermore, the functional liquid coating on the nozzle further enhances the functionality of the cat food pellets.

[0041] Example 3, as Figure 2 , Figure 6 and Figure 10 As shown, based on Embodiments 1 and 2, it further includes a stirrer 28 rotatably installed in the feed hopper 3, a motor 29 installed on the feed hopper 3 with its output shaft connected to the stirrer 28, a moisture sensor 30 installed inside the feed hopper 3, two feeding boxes 31 installed on each side of the feed hopper 3, a sealing cover installed on each feeding box 31, feeding pipes 32 installed on each feeding box 31 with their output ends extending into the feed hopper 3, and air pipes 33 installed on each feeding box 31 with their output ends extending into the two feeding boxes 31 respectively, and the output ends of the two air pipes 33 being aligned with the input ends of the two feeding pipes 32 respectively.

[0042] It is important to understand that motor 29 drives agitator 28 to rotate, causing agitator 28 to mix the cat food ingredients in feed hopper 3. Two feeding bins 31 are filled with cat food ingredients with high moisture content and cat food ingredients with low moisture content, respectively. Two blower pipes 33 are connected to a compressed air system. Moisture sensor 30 detects the moisture content of the cat food ingredients in feed hopper 3. When the moisture content is lower than the standard, the solenoid valve of the blower pipe 33 on the feeding bin 31 containing high-moisture cat food is opened, allowing compressed air to be blown into the feeding bin 31 through the corresponding blower pipe 33. The compressed air pneumatically delivers the high-moisture cat food ingredients into feed hopper 3 through feeding pipe 32, thereby adjusting the moisture content of the cat food ingredients in feed hopper 3. Similarly, when moisture sensor 30 detects that the moisture content of the cat food ingredients in feed hopper 3 is higher than the standard, low-moisture cat food ingredients are fed into feed hopper 3, thereby adjusting the moisture content of the cat food ingredients in feed hopper 3.

[0043] As an alternative, the feeding of the feed box 31 can also be achieved using a screw conveyor or belt conveyor to accommodate raw materials of different shapes; the moisture sensor 30 can be replaced with an infrared moisture meter or a capacitive moisture meter to meet different detection accuracy requirements; in addition, a one-way valve (not shown in the figure) is provided at the connection between the blower pipe 33 and the feed box 31 to prevent material backflow; the end of the feed pipe 32 that extends into the feed hopper 3 is provided with a diffuser (not shown in the figure) to ensure uniform material distribution; the blades of the agitator 28 adopt a detachable structure for easy cleaning and replacement.

[0044] Compared with existing technologies, this embodiment achieves automatic adjustment of the moisture content of cat food raw materials through closed-loop control of moisture sensors and feeding systems, keeping the materials in the optimal forming state at all times, improving the stability of cold pressing and product quality, and the overall structure is highly modular, making it easy to maintain and expand.

[0045] like Figures 1 to 11 As shown, the present invention discloses a cold-pressed raw meat and bone cat food processing technology and equipment. During operation, the cat food raw materials in the feed hopper 3 are first mixed evenly by the mixer 28. The moisture sensor 30 detects the moisture content in real time. When the moisture content deviates from the standard value, the corresponding feeding box 31 is controlled to provide pneumatic feeding through the blower pipe 33 and the feeding pipe 32, adding high-moisture or low-moisture raw materials to the feed hopper 3 to adjust to the standard value. The cat food raw materials with adjusted moisture content enter the extruder 2, which conveys them downwards. After being shaped by the upper mold 4, the cat food raw materials are input into multiple forming cavities of the lower mold 6 at the feeding position on the turntable 5. During the feeding process, the extrusion force of the extruder 2 presses the cat food raw materials into the forming cavities and pushes the top block 20 and the lower template 18 downwards. The spring 19 is stretched and stored, while the lower template 18 is limited and locked by the limiting pin 22 of the locking component. After the multiple forming cavities are filled, the turntable 5 further drives the lower mold 6 to the forming position. During this process, the scraper 3... 4. The upper surface of the scraping turntable 5 scrapes away excess cat food material on the lower mold 6. The cat food material in the multiple forming cavities of the upper and lower molds 6 is cold-pressed at the forming position. The heater 7 operates to heat, cook, dry, and solidify the cold-pressed cat food. The turntable 5 further drives the lower mold 6 to the discharge position. At the discharge position, the electromagnetic push rod 23 pushes the limit pin 22 to unlock the lower mold plate 18. The elastic force of the spring 19 is released, pushing the top block 20 upward to push the formed cat food pellets out of the lower mold 6. The turntable 5 further drives the lower mold 6 to the unloading position. The guide plate 25 guides the formed cat food on the turntable 5 out of the turntable 5 to complete the unloading and collection. The turntable 5 further drives the lower mold 6 to the pre-treatment position. At the pre-treatment position, the nozzle 26 coats the forming cavity with functional liquid. At the same time, the capsules or pellets in the auxiliary material box 14 are put into the forming cavity through the feeding roller 15 to prepare for the next cold-pressed cat food forming. Repeat the above steps to achieve continuous cold-pressed forming of cat food.

[0046] The main beneficial effects achieved by this invention include: 1. Multiple lower molds are set on the turntable and multiple workstations are integrated to realize continuous cold pressing and forming of cat food, resulting in high work efficiency; 2. Automatically adjusts the moisture content of the cat food raw materials in the feed hopper to improve the quality of cold-pressed cat food. 3. When the mold reaches below the nozzle, the functional liquid is fed into the nozzle through the delivery pipe and sprayed downwards, so that the functional liquid is coated on the surface of the cat food raw material, thereby improving the functionality of the cat food pellets. 4. Because the pressure on the cat food ingredients during filling is greater than the cold pressing pressure, the cat food is cold pressed into shape, making the overall structure simpler. 5. When the feeding roller rotates, it takes out the capsules or pellets in the auxiliary material box through multiple feeding holes and puts them into multiple forming cavities on the lower mold, so that the cold-pressed cat food pellets have the corresponding functions. 6. Multiple push blocks extend into the multiple forming cavities of the lower mold below them and push the formed cat food downwards out of the turntable and lower mold, completing the cat food discharge and unloading, with high work efficiency; 7. The closed-loop control of the moisture sensor and feeding system enables automatic adjustment of the moisture content of cat food raw materials, which improves the stability of cold pressing and product quality. The overall structure is highly modular, making it easy to maintain and expand.
