Description

Technical Field

[0001] This invention belongs to the field of animal feed production technology, and relates to a monkey food production equipment, and more particularly to an automated preparation method and apparatus for laboratory monkey food. Background Technology

[0002] Biomedicine is a science that uses biological and engineering techniques to study and solve problems in life sciences. Researching new drugs is one manifestation of biomedicine, and determining the success of a new drug development requires numerous clinical trials. The most important aspect is confirming whether it can treat a certain disease / type of disease, assessing efficacy tests and drug evaluation results, and determining whether it will cause adverse reactions in the human body.

[0003] Currently, modeling is frequently used in new drug research, with monkeys, particularly cynomolgus monkeys, being the most closely related to humans. Cynomolgus monkeys share over 95% genetic material homology with humans and are highly similar in tissue structure, immunity, physiology, and metabolism. Therefore, cynomolgus monkeys have a significant comparative advantage in biomedical research and have become ideal animal models for basic and preclinical research aimed at addressing human health and disease issues. The method for modeling new drugs involves first administering a specific drug to experimental cynomolgus monkeys, which can induce a specific disease. Then, experimental cynomolgus monkeys with the specific disease are given a quantitative dose of the new drug for treatment, and the therapeutic effects are observed and evaluated in real time.

[0004] To control the dosage of medication ingested by cynomolgus monkeys and avoid the drawbacks of traditional methods that rely on dissolving medication for feeding, a common practice is to feed them palatable extruded monkey food. This involves precisely mixing medication into the extruded food, thus controlling the amount of medication consumed. However, current methods for producing medicated extruded monkey food typically involve manually drilling holes and then manually inserting the medication into them. This results in low production efficiency, and the medication is prone to falling out of the food before consumption. Summary of the Invention

[0005] To address the aforementioned problems in the prior art, this invention proposes an automated preparation device for experimental monkey food that can automatically punch holes and add medication.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The first aspect of this invention is to provide an automated preparation device for laboratory monkey food, comprising a frame, a tunnel oven, and a collection bin arranged sequentially, wherein the frame is equipped with a mesh conveyor belt, a perforated powder dispenser, and a metering dosing device, wherein:

[0008] The frame includes a belt conveyor in the middle and a storage bin, a powder bin, and a dosing bin, which are divided by inclined plates at the top. The storage bin is filled with several puffed monkey food pellets. The powder bin is located to the upper right of the storage bin, and its bottom discharge port is located behind the bottom discharge port of the storage bin. The mesh conveyor belt is horizontally installed in the belt conveyor and is located below the bottom discharge ports of the storage bin and the powder bin.

[0011] Furthermore, in the aforementioned automated monkey food preparation device, the frame further includes several partitions and a sliding plate, wherein:

[0012] Several of the aforementioned partitions are spaced apart on the inclined plate at the bottom of the storage bin, with their upper ends extending to the feeding hole opened on the front side wall of the frame and their lower ends extending to the discharge port at the bottom of the storage bin.

[0013] The flat plate is located at the bottom of the partition between the bottom discharge port of the storage silo and the bottom discharge port of the powder silo, so as to flatten and place the puffed monkey food that is lowered from the storage silo onto the grid conveyor belt.

[0014] Furthermore, in the aforementioned automated monkey food preparation device, the mesh conveyor belt includes a support frame, a conveyor belt, and several storage units, wherein:

[0015] The support frame is detachably installed in the belt mounting bin and is equipped with a conveyor belt. The front end of the conveyor belt is located at the discharge port at the bottom of the storage bin, and the rear end extends to the tunnel-type drying oven.

[0016] Several storage units are spaced apart on the conveyor belt, and each storage unit is U-shaped and divided into several storage boxes by baffles. The depth of each storage box is less than the height of the puffed monkey food and is arranged in conjunction with the platen.

[0017] Furthermore, in the aforementioned automated preparation device for experimental monkey food, the perforated powder dispenser also includes a limiting plate and a return spring, wherein:

[0018] There are two limiting plates, which are fixedly installed on the frame on the front and rear sides of the bottom outlet of the powder hopper, respectively. Vertical square holes are opened on them, and the connecting shaft that can slide up and down is inserted into the square holes.

[0019] There are two reset springs, which are respectively set at the bottom of the square hole of the limiting plate, and their tops are abutting and connected to the connecting shaft.

[0020] Furthermore, in the aforementioned automated monkey food preparation device, the perforating powder dispenser also includes a pin and several connecting rods, wherein:

[0021] The ejector pin is coaxially disposed inside the fixed sleeve, and its top end is fixed to the opening at the top of the fixed sleeve by a plurality of the connecting rods, while its lower end extends downward into the punching cone.

[0022] Furthermore, the upper middle part of the ejector pin has an ejector pin sliding hole corresponding to the strip-shaped sliding hole along its axial direction, and the pressure rod that can slide up and down is transversely inserted into the ejector pin sliding hole.

[0023] Furthermore, in the aforementioned automated preparation device for experimental monkey food, both the fixing sleeve and the perforating cone are hollow tubular structures, wherein:

[0024] The top end of the fixed sleeve is connected to the powder lowering plate, and its top opening is arranged corresponding to the discharge port in the groove on the powder lowering plate;

[0025] The top end of the punch is fixedly connected to the pressure rod, and the lower end is a hollow frustum shape, with several powder outlet holes arranged at intervals along the outer peripheral wall of the lower frustum.

[0026] Furthermore, in the aforementioned automated preparation device for experimental monkey food, a limiting protrusion is provided on the hole wall at the lower end of the fixed sleeve, and a limiting groove is formed on the outer wall of the perforating cone along its radial direction, with the limiting protrusion slidably embedded in the limiting groove.

[0027] Furthermore, in the aforementioned automated preparation device for experimental monkey food, the inlet tube is tilted at an angle of 40-50° relative to the vertical direction, and the upper and lower ends of the inlet tube are smoothly connected to the conical dispensing trough and the dispensing sleeve.

[0028] The inclination angle of the discharge pipe relative to the vertical direction is 15-35°, and the upper end of the discharge pipe is smoothly connected to the dispensing sleeve, while the lower end outlet faces the corresponding storage box on the mesh conveyor belt.

[0029] Furthermore, in the aforementioned automated preparation device for experimental monkey food, the extruded monkey food is a square or rectangular block structure with rounded edges, and the drilled holes opened by the perforating powder dispenser are through holes with a large opening at the top and a small opening at the bottom.

[0030] Furthermore, in the automated preparation device for experimental monkey food, the medicine is in the form of granules, tablets, elliptical shapes, round blocks, or round capsules.

[0031] A second aspect of the present invention is to provide an automated method for preparing monkey food for laboratory monkeys using the aforementioned device, comprising the following steps:

[0032] (1) In advance, block-shaped puffed monkey food is laid in several storage channels of the storage silo; molten powder is added to the powder silo in advance, the molten powder is a sugar that has a certain binding and palatability after being heated and melted; and medicine is added to the medicine preparation silo in advance, so that each medicine inlet tube is filled with medicine.

[0033] (2) Start the mesh conveyor belt to move the storage box on it forward. At the same time, control the opening and closing of the electric slide valve at the bottom of the storage bin to control the puffed monkey food to fall into the corresponding storage box below in sequence under its own gravity.

[0034] (3) The storage box filled with puffed monkey food is moved to the position below the punching cone by the mesh conveyor belt. The eccentric wheel is driven to rotate by the drive motor. During the rotation, the eccentric wheel squeezes or releases the squeeze on the driven wheel. The punching cone is moved up and down synchronously by the connecting shaft to cut the puffed monkey food to form holes. At the same time, the molten powder enters the hole of the punching cone below from the fixed sleeve and is discharged from the powder outlet at the bottom of the punching cone into the hole of the puffed monkey food.

[0035] (4) The storage box filled with puffed monkey food is moved to the position below the dispensing pipe by the mesh conveyor belt. When the eccentric wheel rotates, it drives the dispensing shaft to rotate synchronously through the connecting rod. The medicine enters the dispensing pipe through the dispensing hole and slides down along the hole of the dispensing pipe, automatically falling into the hole of the puffed monkey food below, thus achieving the purpose of dispensing medicine at intervals.

[0036] (5) Continue to use the mesh conveyor belt to drive the storage box filled with puffed monkey food to send the puffed monkey food after punching, adding powder and medicine into the tunnel oven for drying and solidification. Control the drying temperature to 30-45℃ so that the molten powder melts and binds and fixes the medicine in the holes of the puffed monkey food, forming a block puffed monkey food with excellent palatability, which is easy for crab-eating macaques to eat.

[0037] (6) Continue to move the storage box filled with puffed monkey food forward by the grid conveyor belt. When the puffed monkey food loaded with medicine moves to the end of the grid conveyor belt, the storage box flips down and the puffed monkey food loaded with medicine falls into the collection bucket, thus completing the automatic collection of puffed monkey food.

[0038] (7) Repeat steps (2), (3), (4), (5) and (6) above to achieve continuous feeding, punching, powdering, drug addition, drying and collection processes, and achieve automated production of medicated monkey food for experimental monkeys.

[0039] The present invention adopts the above technical solution and has the following technical effects compared with the prior art:

[0040] (1) The present invention is used to perform secondary processing on the finished puffed monkey food. The puffed monkey food is conveyed forward in an array by a mesh conveyor belt in batches. A punching powder dispenser is used to accurately punch holes in the puffed monkey food flowing below and fill it with molten powder. The punched puffed monkey food is then accurately injected into the holes by a quantitative dosing device and sent into a tunnel oven for drying and fixing. The automatic punching, powdering and dosing processes are realized in sequence. The degree of automation is high and the efficiency of punching and dosing is greatly improved.

[0041] (2) The punching powder dispenser and the quantitative dosing device are driven and controlled by the same motor. While the punching powder dispenser uses the eccentric wheel to control the pressure rod to move up and down to achieve the purpose of automatic punching and powdering, the eccentric linkage structure is used to synchronously control the rotation of the dispensing shaft on the quantitative dosing device, thereby controlling the opening and closing of the inlet pipe and the outlet pipe, and achieving the purpose of automatic dosing of the agent. Through structural innovation, the punching powder dispenser and the quantitative dosing device are linked together and use the same motor, saving equipment investment costs.

[0042] (3) The mesh conveyor belt adopts a mesh structure design. By setting up several arrayed storage boxes on the conveyor belt, the volume of the holes in the storage boxes is slightly larger than the volume of the puffed monkey food. The puffed monkey food can fall from the storage bin into the corresponding storage box and be laid flat under the action of the plate, which is convenient for subsequent drilling on its top.

[0043] (4) A punching powder dispenser with a specific structural design is provided with several sets of fixed sleeves and punching cones at intervals. The fixed sleeves are fixed at the discharge port at the bottom of the powder bin by the lower powder plate. The punching cones move up and down under the drive of the pressure rod, so as to quickly punch holes in the puffed monkey food that has moved to the bottom of the punching cone.

[0044] (5) The pressure rod contacts the eccentric wheel through the driven wheels at both ends. The eccentric wheel pushes the pressure rod up and down in the square hole of the limiting plate under the drive of the transmission shaft, thereby realizing the drive control of the pressure rod. At the same time as the transmission shaft rotates, it also plays the role of feeding material, pushing the molten powder in the powder bin above to the feeding port on the powder plate, thereby realizing the purpose of filling the drill hole with molten powder while drilling.

[0045] (6) By designing the lower end of the punch as a hollow frustum, the holes drilled in the puffed monkey food are through-hole structures with a large opening at the top and a small opening at the bottom. This ensures that the medicine will not leak out when it is accurately put into the hole. It also makes it easier for the medicine to be fixed in the hole by the molten powder when drying in the tunnel oven. At the same time, the molten powder effectively improves the palatability of the monkey food and makes it easier for crab-eating macaques to eat.

[0046] (7) The automated preparation device for experimental monkey food provided by the present invention uses existing puffed finished monkey food as raw material and adopts a grid conveyor belt to realize a continuous production and conveying line. Through the equipped punching powder dispenser, quantitative dosing device and tunnel oven, automatic punching, powdering, dosing and drying and solidification are realized in sequence. It effectively solves the problems of low production efficiency, high labor cost, time and labor and easy drug fall-off of the existing processing method of drilling holes and then manually adding drugs. It has good practicality and promotion application value. Attached Figure Description

[0082] The present invention will now be described in detail and specifically through specific embodiments to enable a better understanding of the invention. However, the following embodiments do not limit the scope of the invention.

[0083] In some of these embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, an automated preparation device for experimental monkey food is provided. This automated preparation device for experimental monkey food uses existing extruded monkey food products as raw materials and realizes a series of integrated operations such as automatic punching, powdering, drug addition, and drying and solidification. It mainly includes a frame 100, a grid conveyor belt 200, a punching powder dispenser 300, a quantitative drug adder 400, a tunnel drying oven 500, and a collection tank 800.

[0084] The mesh conveyor belt 200, the perforating powder dispenser 300, and the metering dosing device 400 are all mounted on the frame 100. The mesh conveyor belt 200 is used to convey the puffed monkey food 600 in an array to align with the perforating powder dispenser 300 and the metering dosing device 400. One end of the mesh conveyor belt 200 is located inside the frame 100, and the other end extends into the tunnel-type drying oven 500. The perforating powder dispenser 300 is used to automatically perforate the puffed monkey food 600 and simultaneously add molten powder into the holes during the perforation process. The molten powder can be sugar, or a mixture of sugar and rice flour, yam powder, etc., which has a certain degree of binding and palatability after being heated and melted.

[0085] The metering dispenser 400 is used to precisely add medication 700 into the pores of the puffed monkey food 600 after the molten powder has been added. The tunnel oven 500 is used to heat and dry the puffed monkey food 600 after the molten powder and medication have been added. The molten powder melts when heated and has a certain adhesive property, which can fix the medication 700 in the pores. The collection bucket 800 is located at the outlet of the tunnel oven 500 and is used to collect the puffed monkey food 600 after it has been heated and solidified.

[0086] Specifically, such as Figure 4 , Figure 6 , Figure 8 , Figure 10 , Figure 12 and Figure 13 As shown, the frame 100 mainly includes a belt conveyor hopper 105 located in the middle and a storage hopper 101, a powder hopper 103, and a dosing hopper 104 located in the upper part, which are divided by inclined plates. The lower cross-sections of the storage hopper 101, the powder hopper 103, and the dosing hopper 104 are all inverted conical structures. The powder hopper 103 is located at the upper right of the storage hopper 101, and the dosing hopper 104 is located at the upper right of the powder hopper 103. Meanwhile, the bottom discharge port of the powder hopper 103 is located behind the bottom discharge port of the storage hopper 101, and the discharge ports of both are arranged side-by-side.

[0087] The belt conveyor hopper 105 is located below the bottom discharge port of the storage hopper 101 and the powder hopper 103, and the mesh conveyor belt 200 is horizontally installed inside it. The rear end of the mesh conveyor belt 200 extends into the tunnel oven 500. The extruded monkey food 600 that can be received from the front storage hopper 101 is conveyed forward sequentially through the mesh conveyor belt 200. After being punched and powdered by the punching powder dispenser 300, it is then fed with medicine at the outlet of the metering dosing device 400 and sent into the tunnel oven 500 for drying and heating. Finally, it is conveyed out from the rear end of the tunnel oven 500 and falls into the collection bucket 800.

[0088] In addition, such as Figure 10 , Figure 11 , Figure 12 and Figure 13As shown, a storage box 108 is also provided at the bottom of the frame 100 for temporarily storing puffed monkey food 600, molten powder, or medicine, etc. Switch doors can be installed on both sides of the storage box 108 as needed. A drive shaft mounting hole 109, a limit plate mounting hole 110, and a dispensing shaft mounting hole 111 are respectively provided on the left and right side walls of the frame 100. The drive shaft mounting hole 109 is used to install the drive shaft 301, the limit plate mounting hole 110 is used to install the limit plate 308, and the dispensing shaft mounting hole 111 is used to install the dispensing shaft 405. The dispensing shaft mounting hole 111 and the limit plate mounting hole 110 are located above and below the drive shaft mounting hole 109, respectively, so that the drive shaft 301 synchronously drives the driven wheel 309 on the limit plate 308 to move up and down and drives the dispensing shaft 405 to rotate. In order to facilitate the installation of the metering dosing device 400, a number of dispensing pipe mounting holes 112 are provided on the rear side wall of the frame 100, and a number of dispensing pipes 404 on the metering dosing device 400 are installed in the dispensing pipe mounting holes 112.

[0089] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 16 , Figure 17 , Figure 18 , Figure 19 and Figure 20 As shown, the punching powder dispenser 300 mainly includes a drive shaft 301, a powder lowering plate 303, a pressure rod 306, and several sets of fixing sleeves 304 and punching cones 305 spaced apart at the bottom of the powder lowering plate 303. The punching powder dispenser 300 precisely punches holes in the puffed monkey food 600, and simultaneously fills the holes in the puffed monkey food 600 with the molten powder in the powder silo 103.

[0090] Both ends of the drive shaft 301 are mounted on the frame 100 via bearings. Depending on the size of the space at the bottom discharge port of the powder silo 103, several stirring rods can be installed on the drive shaft 301. Rotation of the drive shaft 301 drives the stirring rods to rotate, thereby mixing the molten powder in the powder silo 103 and simultaneously pushing the molten powder from the powder silo 103 onto the lower powder plate 303. The lower powder plate 303 is located below the drive shaft 301, and its periphery is fixedly connected to the inner wall of the discharge port. The pressure rod 306 passes laterally through several strip-shaped sliding holes 3041 on the fixed sleeves 304 and is fixedly connected to the corresponding perforating cones 305. The pressure rod 306 is welded to the top of the perforating cones 305.

[0091] like Figure 16 , Figure 17 , Figure 18 and Figure 19 As shown, the fixing sleeve 304 and the perforating cone 305 can be in multiple sets to correspond to several storage boxes 204 on the mesh conveyor belt 200, such that one perforating cone 305 is aligned with one storage box 204 containing puffed monkey food 600. Preferably, the fixing sleeve 304 and the perforating cone 305 are arranged in four sets side by side with intervals, and correspondingly, the storage boxes 204 on the mesh conveyor belt 200 are also arranged in four sets side by side with intervals.

[0092] like Figure 2 , Figure 3 , Figure 16 , Figure 17 , Figure 18 , Figure 19 , Figure 20 , Figure 21 and Figure 22 As shown, to achieve the reciprocating up-and-down movement of the pressure rod 306 and continuously perforate the puffed monkey food 600 flowing below, a cam eccentric design is adopted to transmit the rotational force of the drive shaft 301 to the pressure rod 306, thereby driving the pressure rod 306 to move up and down. Eccentric wheels 302 are respectively provided at both ends of the drive shaft 301, with the ends of the drive shaft 301 connected to the edges of the eccentric wheels 302, so that the drive shaft 301 can drive the eccentric wheels 302 to rotate eccentrically during rotation.

[0093] Furthermore, both ends of the pressure rod 306 are connected to driven wheels 309 via connecting shafts 307. The driven wheels 309 are tactilely connected to the eccentric wheel 302, and one end of the transmission shaft 301 is connected to a drilling drive motor 313, which is mounted on the side wall of the frame 100 via a fixing bracket. When the drilling drive motor 313 is started, it drives the transmission shaft 301 to rotate, and the eccentric wheel 302 rotates synchronously, driving the driven wheels 309 to move up and down. This causes the connecting shaft 307 and the pressure rod 306 to move up and down, which in turn drives the drilling cone 305 to move up and down within the fixing sleeve 304 via the pressure rod 306. During this up-and-down movement, the purpose of drilling holes in the puffed monkey food 600 is achieved.

[0094] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 23 , Figure 24 and Figure 25 As shown, the quantitative dosing device 400 mainly includes a conical dosing trough 401, a dosing inlet pipe 402, a dosing sleeve 403, and a dosing outlet pipe 404 arranged sequentially from top to bottom.

[0095] Specifically, there are several drug inlet pipes 402 and several drug outlet pipes 404 arranged at an inclined interval. The top inlets of several drug inlet pipes 402 are connected to the bottom of the conical drug dispensing trough 401, the bottom outlets of several drug inlet pipes 402 are connected to the upper left tube of the horizontally arranged drug dispensing sleeve 403, and the top inlets of several drug outlet pipes 404 are connected to the upper right tube of the drug dispensing sleeve 403.

[0096] The conical dispensing tank 401 contains a plurality of drugs 700. The dispensing sleeve 403 contains a dispensing shaft 405, which has a plurality of radially arranged dispensing holes 4051 spaced apart. Each dispensing hole 4051 connects to a corresponding inlet pipe 402 and outlet pipe 404. The inlet and outlet of the dispensing sleeve 403, connecting the inlet pipe 402 and outlet pipe 404, are arranged diagonally to form a closable valve structure with the dispensing holes 4051 on the dispensing shaft 405. When the dispensing holes 4051 rotate to connect with the inlet pipe 402 and outlet pipe 404 respectively, a passage is formed, and the drugs 700 in the inlet pipe 402 enter the outlet pipe 404 through the dispensing holes 4051. When the dispensing shaft 405 continues to rotate, causing the dispensing hole 4051 to be misaligned with the lower outlet of the inlet pipe 402 and the upper inlet of the outlet pipe 404, a closed state is formed. The drug 700 in the outlet pipe 404 is blocked by the dispensing shaft 405 and cannot enter the outlet pipe 404.

[0097] Furthermore, to provide power to the dispensing shaft 405 and control its rotation, both ends of the dispensing shaft 405 are respectively mounted in the dispensing shaft mounting 111 on the two side walls of the frame 100 via bearings. A transmission wheel 406 is mounted on one end of the dispensing shaft 405, and a first pin is positioned eccentrically on the edge of the transmission wheel 406. This first pin is hinged to a second pin at the center of the eccentric wheel 302 via a connecting rod 407. During rotation, the eccentric wheel 302 synchronously drives the dispensing shaft 405 to rotate via the connecting rod 407, thereby achieving the purpose of intermittently dispensing the medicine 700. The frequency of the medicine 700 falling is consistent with the frequency of punching and adding powder to the extruded monkey food 600 and the conveying speed of the mesh conveyor belt 200, ensuring the continuity and accuracy of the punching, adding powder, and dispensing processes of the same extruded monkey food 600.

[0098] The automated monkey food preparation device for experimental monkeys provided in this embodiment performs secondary processing on the finished puffed monkey food 600. The puffed monkey food 600 is conveyed forward in an array by a mesh conveyor belt 200. A punching and powdering device 300 is used to precisely punch holes in the puffed monkey food 600 flowing below and simultaneously fill it with molten powder. After punching, the puffed monkey food with holes passes below the discharge port of the drug discharge pipe 404 on the quantitative drug dispenser 400, where the drug 700 is precisely added into the holes made in the puffed monkey food 600. Then, it is sent into a tunnel-type drying oven 500 for drying and fixing. The device realizes the automatic punching, powdering, and drug addition processes in sequence, with a high degree of automation and greatly improved punching and drug addition efficiency.

[0099] In some of these embodiments, such as Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 11 and Figure 12 As shown, the frame 100 also includes several partitions 102 and a sliding plate 106. The partitions 102 are spaced apart on the inclined plate at the bottom of the storage hopper 101, with their upper ends extending to the feeding hole on the front side wall of the frame 100 and their lower ends extending to the discharge port at the bottom of the storage hopper 101. Preferably, there are three partitions 102, forming four independent inclined storage channels with the two side walls of the storage hopper 101. Several pieces of puffed monkey food 600 are sequentially laid along the inclined surface of each storage channel. Through the electric sliding valve at the discharge port at the bottom of the storage hopper 101, the puffed monkey food 600 falls into the storage box 204 below under its own gravity.

[0100] It should be noted that, to ensure the puffed monkey food 600 falls flat into the storage box 204 without vertical displacement, a leveling plate 106 is specially provided. The leveling plate 106 is located at the bottom of the partition between the bottom discharge port of the storage hopper 101 and the bottom discharge port of the powder hopper 103, positioned above the storage box 204 in the forward direction. Using the forward-moving mesh conveyor belt 200, the puffed monkey food 600, even if vertically displaced, is leveled and placed flat in the storage box 204 by the leveling plate 106, thus achieving the purpose of leveling and placing the puffed monkey food 600.

[0101] In some of these embodiments, such as Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 14 and Figure 15As shown, to facilitate the array-style conveying of the block-shaped extruded monkey food 600, the mesh conveyor belt 200 with a specific structural design is used. The mesh conveyor belt 200 mainly includes a support frame 201, a conveyor belt 202, and several storage boxes 204. The storage boxes 204 are arranged in an array on the surface of the conveyor belt 202. The conveyor belt 202 uses a traditional conveyor, such as a roller conveyor or chain conveyor driven by a power motor, which has a certain impact resistance and can meet the impact force during the punching process.

[0102] The support frame 201 is detachably installed inside the belt mounting bin 105 and is equipped with a conveyor belt 202. The front end of the conveyor belt 202 is located at the bottom discharge port of the storage bin 101, and the rear end extends to the tunnel oven 500. Several storage units 203 are spaced apart on the conveyor belt 202, and each storage unit 203 is U-shaped and divided into several storage boxes 204 by baffles. The depth of the storage boxes 204 is less than the height of the extruded monkey food 600, and they are arranged in conjunction with the platen 106.

[0103] The mesh conveyor belt 200 adopts a mesh structure design. By setting several arrayed storage boxes 204 on the conveyor belt, the volume of the holes in the storage boxes 204 is slightly larger than the volume of the puffed monkey food 600. The puffed monkey food can fall from the storage bin into the corresponding storage box and be laid flat by the action of the flat plate 106, which facilitates subsequent drilling of holes on its top.

[0104] In some of these embodiments, such as Figure 15 , Figure 16 , Figure 17 , Figure 18 , Figure 19 , Figure 20 , Figure 21 and Figure 22 As shown, the punching powder dispenser 300 also includes a limiting plate 308 and a return spring 310. The limiting plate 308 is used to limit the up and down movement of the connecting shaft 307 and the pressure rod 306, so as to prevent the pressure rod 306 from shaking during the up and down movement.

[0105] Specifically, there are two limiting plates 308, which are fixedly installed on the frame on the front and rear sides of the bottom discharge port of the powder silo 103, respectively. Vertical square holes are opened on them, and the connecting shaft 307, which can be slidably arranged up and down, is inserted into the square holes. The connecting shaft 307 can move up and down in the square holes under the drive of the driven wheel 309 at its end.

[0106] Two return springs 310 are respectively positioned at the bottom of the square hole in the limiting plate 308, and their tops are abutted against the connecting shaft 307. The return springs 310 are used to support the pressure rod 306 to return to its original position and move upward when it is not squeezed by the eccentric wheel 302. The pressure rod 306 contacts the eccentric wheel 302 through the driven wheels 309 at both ends. Driven by the transmission shaft 301, the eccentric wheel 302 pushes the pressure rod 306 up and down in the square hole of the limiting plate 308, thereby realizing the drive control of the pressure rod 306. At the same time, the transmission shaft 301 also plays a role in feeding material, pushing the molten powder in the powder hopper above to the feeding port on the powder feeding plate 303, thereby realizing the purpose of filling the drilled hole with molten powder while drilling.

[0107] In some of these embodiments, such as Figure 17 , Figure 18 , Figure 19 , Figure 20 , Figure 21 and Figure 22 As shown, to facilitate the discharge of the feed removed by punching from the extruded monkey food 600 or from the punching cone 305, the punching cone 305 adopts a hollow frustum structure. The punching powder dispenser 300 also includes a ejector pin 311 and several connecting rods 312, wherein: the ejector pin 311 is coaxially disposed within the fixing sleeve 304, its top end is fixed to the opening at the top of the fixing sleeve 304 by several connecting rods 312, and its lower end extends downward into the punching cone 305.

[0108] To avoid structural conflict with the pressure rod 306, a corresponding axial sliding hole is formed in the upper middle part of the ejector pin 311, and the pressure rod 306, which can slide up and down, is transversely inserted into the sliding hole. The diameter of the pressure rod 306 is smaller than the inner diameter of the punching cone 305. When the punching cone 305 is in the high position, the lower end of the punching cone 305 also serves to block the powder outlet hole 3052. When the punching cone 305 is in the low position, the molten powder falls from the top through the gap between the punching cone 305 and the ejector pin 311, and is finally discharged from the powder outlet hole 3052 into the cut hole.

[0109] In some of these embodiments, such as Figure 7 , Figure 17 , Figure 18 , Figure 19 , Figure 20 , Figure 21 and Figure 22As shown, both the fixing sleeve 304 and the punching cone 305 are hollow tubular structures. The top end of the fixing sleeve 304 is connected to the powder lowering plate 303, and its top opening corresponds to the feeding port in the groove 3031 of the powder lowering plate 303. The top end of the punching cone 305 is fixedly connected to the pressure rod 306, and its lower end is a hollow frustum shape. The outer peripheral wall of the lower frustum has several spaced powder outlet holes 3052, and the bottom end has a sharp annular cutter, which facilitates rapid punching of the puffed monkey food 600.

[0110] By designing the lower end of the perforating cone 305 as a hollow frustum shape, the holes drilled inside the extruded monkey food 600 are through-hole structures with a large opening at the top and a small opening at the bottom. This ensures that when the medicine 700 is precisely added into the hole, it will not leak out. This allows the medicine to be well fixed inside the hole by the molten powder during drying in the tunnel oven 500. At the same time, the molten powder effectively improves the palatability of the monkey food, making it easier for crab-eating macaques to eat.

[0111] Furthermore, to ensure stability during the drilling process and prevent the drilling cone 305 from sliding relative to the fixed sleeve 304 or falling out of the fixed sleeve 304 during its up-and-down movement, a limiting protrusion 3042 is provided on the hole wall at the lower end of the fixed sleeve 304, and a limiting groove 3051 is formed on the outer wall of the drilling cone 305 along its radial direction. The limiting protrusion 3042 is slidably embedded in the limiting groove 3051.

[0112] It should be noted that when the eccentric wheel 302 rotates downward under the drive of the transmission shaft 301, the driven wheel 309 moves downward under the pressure of the eccentric wheel 302 and compresses the return spring 310. The pressure rod 306 synchronously drives the punching cone 305 to move downward and quickly punches the puffed monkey food 600 that has just moved below it. A portion of the puffed monkey food 600 is cut out and enters the hole of the punching cone 305. At the same time, molten powder enters the hole of the punching cone 305 below from the fixed sleeve 304 and is discharged from the powder outlet hole 3052 at the lower end of the punching cone 305 into the punched hole.

[0113] The working principle of the perforated powder dispenser 300 is as follows: When the eccentric wheel 302 rotates upward, it disengages from the driven wheel 309, releasing the pressure on the driven wheel 309. At this time, the connecting shaft 307 is pushed upward by the return spring 310, synchronously driving the pressure rod 306 and its perforating cone 305 to move upward. During this process, the perforating cone 305 and the portion of feed cut off by its holes move upward synchronously, and after moving up a certain distance, they contact the ejector pin 311 fixedly installed in the fixed sleeve 304. The ejector pin 311 pushes the portion of feed cut off from the perforating cone 305 and scatters it between the two adjacent storage boxes 204 that are moving forward. At the same time, it should be noted that when the eccentric wheel 302 rotates, it synchronously drives the dispensing shaft 405 to rotate through the connecting rod 407, realizing the purpose of intermittently dispensing the medicine 700.

[0114] In other words, within one rotation cycle, the eccentric wheel 302 sequentially performs the actions of punching, adding powder, unloading, and adding chemicals. To ensure consistency in each step, a PLC controller is used to control the drive motors of the mesh conveyor belt 200 and the punching and powder dispensing device 300, respectively, so that punching, adding powder, unloading, and adding chemicals operate at the same frequency, thereby maximizing work efficiency and achieving continuous production.

[0115] In some of these embodiments, such as Figure 4 , Figure 5 , Figure 6 , Figure 8 , Figure 9 , Figure 23 , Figure 24 and Figure 25 As shown, to ensure the stability of drug administration, the inlet pipe 402 is tilted at an angle of 40-50° relative to the vertical direction, and the upper and lower ends of the inlet pipe 402 are smoothly connected to the conical dispensing trough 401 and the dispensing sleeve 403. The outlet pipe 404 is tilted at an angle of 15-35° relative to the vertical direction, and the upper end of the outlet pipe 404 is smoothly connected to the dispensing sleeve 403, with the lower outlet facing the corresponding storage box 204 on the mesh conveyor belt 200.

[0116] The working principle of the metering dosing device 400 is as follows: Utilizing the weight of the medication 700, the medication 700 in the conical dosing trough 401 slides along the hole in the inlet pipe 402 to the dispensing sleeve 403. When the dispensing hole 4051 is misaligned with the inlet pipe 402 and the outlet pipe 404, the medication 700 is blocked by the dispensing shaft 405 and cannot fall freely. When the dispensing shaft 405 rotates, the dispensing hole 4051 connects the inlet pipe 402 and the outlet pipe 404. The medication 700 then enters the outlet pipe 404 through the dispensing hole 4051 and slides down along the hole in the outlet pipe 404, automatically falling into the hole of the extruded monkey food 600 below.

[0117] In some of these embodiments, such as Figure 22 As shown, to overcome the problem of existing round extruded monkey food 600 easily rolling off and to facilitate consumption by cynomolgus monkeys, the extruded monkey food 600 is designed as a square or rectangular block structure with rounded edges. Furthermore, the drilled holes opened by the perforating powder dispenser 300 are through holes with a larger opening at the top and a smaller opening at the bottom, facilitating the addition and fixation of the medication 700. The medication 700 is in granular, tablet, round block, or round capsule form.

[0118] It should also be noted that when the puffed monkey food 600 after being punched, powdered, and medicated is sent into the tunnel oven 500 for drying and curing, the drying temperature of the tunnel oven 500 needs to be controlled. For example, a drying temperature of 30-45℃ can satisfy the melting of the molten powder to bind and fix the medicine 700, while avoiding high temperature from damaging the medicine 700 and affecting its efficacy.

[0119] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the automated monkey food preparation device for laboratory monkeys provided by this invention has the following working principle:

[0120] (1) Block-shaped puffed monkey food 600 is laid in several storage channels of storage bin 101 in advance; molten powder is added to powder bin 103 in advance, the molten powder is a sugar that has a certain binding and palatability after being heated and melted; and medicine 700 is added to medicine bin 104 in advance, so that each medicine inlet pipe 402 is filled with medicine 700.

[0121] (2) Start the grid conveyor belt 200, which drives the storage box 204 on it to move forward. At the same time, by controlling the opening and closing of the electric slide valve at the bottom of the storage bin 101, the puffed monkey food 600 is controlled to fall into the corresponding storage box 204 below in sequence under its own gravity.

[0122] (3) The storage box 204 filled with puffed monkey food is moved to the position below the punching cone 305 by the mesh conveyor belt 200. The eccentric wheel 302 is driven to rotate by the drive motor. During the rotation, the eccentric wheel 302 squeezes or releases the squeeze on the driven wheel 309. The punching cone 305 is moved up and down synchronously by the connecting shaft 307 to cut the puffed monkey food 600 to form holes. At the same time, the molten powder enters the hole of the punching cone 305 below from the fixed sleeve 304 and is discharged from the powder outlet hole 3052 at the lower end of the punching cone 305 into the hole of the puffed monkey food 600.

[0123] (4) The storage box 204 filled with puffed monkey food is driven by the mesh conveyor belt 200 to continue moving to the position below the medicine discharge pipe 404. When the eccentric wheel 302 rotates, it drives the medicine distribution shaft 405 to rotate synchronously through the connecting rod 407. The medicine 700 enters the medicine discharge pipe 404 through the medicine distribution hole 4051 and slides down along the hole of the medicine discharge pipe 404, automatically falling into the hole of the puffed monkey food 600 below, thus achieving the purpose of intermittently delivering the medicine 700.

[0124] (5) Continue to use the mesh conveyor belt 200 to drive the storage box 204 filled with puffed monkey food to send the puffed monkey food 600, which has been punched, powdered and doped, into the tunnel oven 500 for drying and solidification. Control the drying temperature to 30-45℃ so that the molten powder melts and binds and fixes the agent 700 in the holes of the puffed monkey food 600, forming a block puffed monkey food with excellent palatability, which is easy for crab-eating macaques to eat.

[0125] (6) Continue to move forward by the mesh conveyor belt 200 to transport the storage box 204 filled with puffed monkey food forward. When the puffed monkey food 600 loaded with medicine 700 moves to the end of the mesh conveyor belt 200, the storage box 204 flips down and the puffed monkey food 600 loaded with medicine 700 falls into the collection bucket 800, completing the automatic collection of puffed monkey food.

[0126] (7) Repeat steps (2), (3), (4), (5) and (6) above to achieve continuous feeding, punching, powdering, drug addition, drying and collection processes, and achieve automated production of medicated monkey food for experimental monkeys.

[0127] This invention uses existing puffed monkey food as raw material and adopts a grid conveyor belt 200 to realize a continuous production and conveying line. Through the equipped perforated powder dispenser 300, quantitative dosing device 400, tunnel drying oven 500 and collection bucket 800, automatic perforation, powder addition, dosing, drying and solidification and finished product collection are realized in sequence. It effectively solves the problems of low production efficiency, high labor cost, time and labor time and easy drug fall-off in the existing processing method of drilling holes and then manually adding drugs. It has good practicality and promotion and application value.

[0128] The specific embodiments of the present invention have been described in detail above, but they are merely examples, and the present invention is not limited to the specific embodiments described above. For those skilled in the art, any equivalent modifications and substitutions to the present invention are also within the scope of the present invention. Therefore, all equivalent transformations and modifications made without departing from the spirit and scope of the present invention should be covered within the scope of the present invention.

Start the mesh conveyor belt, which moves the storage boxes on it forward. At the same time, by controlling the opening and closing of the electric slide valve at the bottom of the storage bin, the puffed monkey food is controlled to fall into the corresponding storage boxes below in sequence under its own gravity. A mesh conveyor belt moves a storage box filled with puffed monkey food to a position below the punching cone. A drive motor drives an eccentric wheel to rotate. During rotation, the eccentric wheel squeezes or releases the driven wheel. The connecting shaft synchronously drives the punching cone to move up and down, cutting out holes in the puffed monkey food. At the same time, molten powder enters the holes of the punching cone from the fixed sleeve and exits from the powder outlet at the bottom of the punching cone into the holes of the puffed monkey food.
