Abstract

The present invention discloses a high-freshness cat food feed processing and feeding device and feeding method, belonging to the field of pet food production. The device utilizes a conveyor chain and a bag-grabbing structure on the bag-grabbing chain to automatically convey the material bags. During the conveying process, a bag-cutting element cooperates to cut the material bags, allowing the raw materials in the material bags to enter the corresponding collecting hoppers. The raw materials are then quantitatively fed into a mixing box via a feeding box. In the mixing box, the raw materials are fully mixed via an airflow mixing element. After mixing, the material is fed via a discharging control element. This device is used to address the problems of manual bag cutting and feeding, which are labor-intensive and prone to box blockage, and the imbalance in the ratio of meat and fruits and vegetables in cat food particles caused by traditional high-speed stirring and mixing.

Description

Technical Field

[0001] The invention belongs to the field of pet food production, and in particular relates to a high-freshness meat cat food feed processing and feeding device and a feeding method thereof. Background Art

[0002] High-fresh meat cat food refers to cat food with fresh meat as the main raw material and a high meat content in the formula, and the cat food also contains auxiliary raw materials such as fruits and vegetables. This type of cat food is closer to the natural meat needs of cats, easier to digest and absorb, and is suitable for cats who pursue a high-protein, low-carb diet. When processing cat food, most of the meat part and the fruit and vegetable part are mixed first and then prepared together, but this causes a large amount of nutrition to be lost in the fruit and vegetable part, such as some vitamins and other nutrients. If the particles are prepared separately and then mixed and fed directly into the finished product processing method, such as using bagged meat particles and bagged fruit and vegetable particles to unpack and mix to complete the feeding process, the problem of nutrient loss can be avoided, but the following problems will still exist:

[0003] 1. The bagged high-freshness meat granules and fruit and vegetable granules need to be fed separately and then mixed. This requires manual or auxiliary equipment to cut the bags, and the raw materials in the bags are sent to the mixing box for mixing to obtain the mixed material. This leads to high labor intensity, low production efficiency, and the bags are easily mixed into the mixing box, causing blockage;

[0004] 2. Mixing in a mixing box generally uses a stirring rod / blade to stir the mixture at high speed, such as CN219897729U. During the stirring and mixing process, the particles are easily broken and the density at the bottom is high and the density at the top is low, which makes the ratio of meat and fruits and vegetables in the prepared cat food unbalanced, affecting the quality of the cat food.

[0021] In a more optimal solution, a bag recovery box is installed on the top frame, the bag recovery box is provided with a bag grabbing inlet and outlet, the loose grabbing structure is installed on the side wall inside the bag grabbing inlet and outlet, and a bag discharge port is installed at the bottom of the bag recovery box.

[0022] A feeding method for high-freshness meat cat food, using the feeding device, comprises the following steps:

[0023] Step 1: Loading raw materials

[0024] The raw material bags are grabbed by the manipulator and placed on the conveyor chain, which conveys the raw material bags to the collecting hopper. During the conveying process, the bag grabbing structure on the bag grabbing chain grabs the raw material bags and cooperates with the conveyor chain to pass the raw material bags through the bag cutting parts, which cuts the bottom of the raw material bags. At this time, the bag grabbing structure is still in the state of grabbing the raw material bags. The bag grabbing structure puts the raw material bags into the bag grabbing inlet and outlet, and the bag grabbing structure releases the raw material bags by the action of the loosening structure. The raw material bags and the bag grabbing structure are separated and finally discharged from the bag outlet.

[0025] Step 2: quantitative discharge

[0026] The raw materials enter the collecting hopper from the cut raw material bags, and the switch valve plate on the top side of the feeding box is adjusted to be in the open state, and the switch valve plate on the bottom side is adjusted to be in the closed state. The raw materials in the collecting hopper fill the feeding box, and then the switch valve plate on the top side of the feeding box is adjusted to be in the closed state, and the switch valve plate on the bottom side is adjusted to be in the open state. A space control plate and a feeding plate are provided inside the feeding box. The space control plate is used to control the size of the space in the feeding box, and the feeding plate delivers the raw materials in the feeding box under the action of the lifting cylinder;

[0027] Step 3, Mix

[0028] The raw materials are quantitatively fed into the mixing box, and the external air flow supply device delivers high-pressure air into the flow equalization chamber. At the same time, the servo motor drives the air flow disk to rotate through the gear transmission at a speed of 1-2 revolutions per second. The high-pressure air flows into the air flow cover through the air outlet and is ejected to the surroundings through the air flow nozzle to mix the raw materials.

[0029] Step 4: Add materials

[0030] After the near-infrared sensor detects that the mixture is evenly mixed, the discharge cylinder drives the discharge barrel upward through the connecting plate, and the material blocking head moves upward. The evenly mixed raw materials are discharged from the mixing box through the discharge barrel by the discharge part for feeding operation.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. The present invention sets an air flow mixer in the mixing box. The slow rotation of the air flow disk ensures that the raw materials inside will not be directly and rigidly collided. Secondly, it drives the air flow nozzle on it to rotate. While rotating, the internal raw materials are blown upward and mixed, so that the raw materials are mixed evenly, effectively reducing the amount of broken materials. Even if a small amount of broken materials appear, they will be evenly mixed in the mixture.

[0033] 2. During the mixing implementation of the present invention, it was found that there would be mixing dead corners around the airflow nozzle. Therefore, the airflow nozzle adopts the structure of an airflow hood and an air outlet. The airflow hood is moved upward under the action of the airflow, and then the airflow injection port and the air outlet are connected. The airflow injection port is evenly distributed circumferentially downward, and the high-pressure airflow ejected will move the raw materials away from the airflow nozzle, solving the problem of dead corners.

[0034] 3. The present invention sets a feeding box between the collecting hopper and the mixing box, and the side top and side bottom of the feeding box are both provided with switch valve plates. By controlling the two switch valve plates, the raw materials in the collecting hopper can enter the pre-set space in the feeding box, and the space is adjusted by the space control part, and is selectively opened and closed according to the addition ratio requirements of different raw materials. A space control plate and a feeding plate are set in the feeding box, and the lifting cylinder is used to drive the feeding plate upward to feed the raw materials into the mixing box.

[0035] 4. In order to complete automatic loading, the present invention places the material bag on the conveyor chain, and uses the conveyor chain to transport the material bag to the bag cutting part. During the transportation, the bag grabbing structure on the upper bag grabbing chain will automatically grab the material bag to ensure that after the material bag is cut, the material bag will not enter the collecting hopper and cause congestion. Secondly, the material bag is automatically released under the action of the loosening structure and recycled. The bag grabbing structure of this case adopts a purely mechanical structure, which has better stability and durability.

[0036] 5. The bag-grabbing structure of the present invention utilizes a vertical body that pierces the bag from the top to facilitate the automatic dropping of the subsequent raw materials. As the contact frame contacts the top of the bag and moves upward relative to the bag, the bag-piercing members move closer together to grasp the pierced portion of the bag. Simultaneously, the anchor head within the vertical body is extended outward to ensure gripping force. Simultaneously, the movable block on the contact frame is restrained by the restraining member and prevents it from returning. Even if one end of the bag has been cut, sufficient conveying power is maintained, preventing the bag from becoming entangled in the bag-cutting member at the end of the conveying process due to insufficient conveying power. Once the bag is cut and all the internal raw materials have been removed, the loosening mechanism activates the restraining member to reset the movable block, allowing the vertical body to return to its vertical position. The anchor head, driven automatically by the internal structure of the vertical body, automatically resets itself, and the bag automatically drops from the bag-piercing member.

[0054] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0055] Example 1

[0056] like Figure 1 As shown, a high-freshness cat food feed processing and feeding device includes:

[0057] like Figure 2 As shown, the mixing assembly includes a main frame 10, on which a feeding hopper 11 is mounted. The feeding hopper 11 includes a mixing box 12 located in the middle and a collecting hopper 13 distributed on the upper and outer sides of the mixing box 12. The collecting hopper 13 and the mixing box 12 are connected by a pipeline. An air flow mixer and an explosion-proof membrane 16 distributed above the air flow mixer are installed in the mixing box 12.

[0058] like Figure 8 As shown, the raw material conveying assembly is provided with multiple groups of raw material conveying assemblies, taking two groups as an example, it can also be in the form of three groups or more circumferentially distributed, the discharge ends of the raw material conveying assemblies are all located above the collecting hopper 13, the raw material conveying assembly includes a top frame 20 installed above the main frame 10, and a plurality of conveying chains 21 are installed on the top frame 20, the conveying chain 21 is used to convey raw material bags, and a bag cutting component 22 is installed on the top frame 20 at the end of the conveying chain 21, and the bag cutting component 22 is used to cut the raw material bags, and the top frames 20 located above the conveying chains 21 are all installed with grabbing chains 23, and the grabbing chains 23 and the conveying chains 21 overlap in upper and lower parts, and the overlapping length is at least the spacing between the two groups of grabbing bag structures, and the grabbing bag chains 23 are installed with several groups of equally spaced grabbing bag structures, and the grabbing bag structures are used to grab the raw material bags, and a loosening structure is installed on the top frame 20 at the tail of the grabbing bag chain 23 to act on the grabbing bag structure to release the raw material bags.

[0059] During implementation, a robotic arm is used to place the raw material bags on the conveyor chain 21. The conveyor chain 21 and the bag grabbing chain 23 are each equipped with a servo motor, and their speeds are synchronized. The bag grabbing structure on the bag grabbing chain 23 constrains the bag from the upper side of the bag for synchronous and speedy conveying. The bag portion that is separated from the conveyor chain 21 at the end of the conveyor chain 21 is driven by the bag grabbing chain 23 to move the bag, and the bag cutting unit 22 cooperates to complete the bag cutting operation. The synchronous and speed-synchronous operation of the two effectively releases the carrying capacity of the bag grabbing chain 23, and the equipment requirements are relaxed as much as possible. The bag grabbing structure can be used for clamping and grabbing, or puncturing and grabbing. Grabbing from the upper part of the bag facilitates the removal of the raw material after cutting. The raw material falls into the collection hopper 13, and the raw material is fed into the mixing box 12. The air flow mixing unit mixes the raw materials entering the mixing box 12, and the explosion-proof diaphragm 16 controls the pressure of the mixing box 12.

[0060] Example 2

[0061] In the feeding device, Figure 2 、 3 As shown, the air flow mixing element includes an air flow disk 17 rotatably installed at the bottom of the mixing box 12, and the air flow disk 17 is equipped with an inlet and outlet and a plurality of air flow nozzles 18 distributed around the inlet and outlet. The bottom of the mixing box 12 is sealed with a flow equalizing bin 19 that communicates with the air flow nozzle 18. The flow equalizing bin 19 is sealed on the outside of the bottom of the air flow disk 17. The flow equalizing bin 19 is externally connected to an air flow supply device. A servo motor 110 is installed in the flow equalizing bin 19. The servo motor 110 drives the air flow disk 17 to rotate through gear transmission. A discharge control component 111 that passes through the flow equalizing bin 19 is installed in the inlet and outlet.

[0062] like Figure 3 、 4 As shown, the airflow nozzle 18 includes an air outlet tube 181 inserted into the airflow disk 17, and the outer side of the air outlet tube 181 is slidably fitted with an airflow cover 182, and the side of the airflow cover 182 is circumferentially distributed with multiple airflow injection ports 183, and the injection outlets of the airflow injection ports 183 gradually deviate from the radial direction of the airflow cover 182 where the injection inlet is located to one side along the airflow injection direction.

[0063] After the raw materials enter the mixing box 12, the servo motor 110 drives the air flow disk 17 to rotate through the gear transmission at a speed of 1-2 turns per second, avoiding rigid collision with the raw materials with a large speed difference as much as possible, effectively solving the problem of broken materials, and the air flow entering the equalizing bin 19 enters the air flow cover 182 through the air outlet 181, and pushes the air flow cover 182 to a certain height. When the air flow injection port 183 and the air outlet 181 are connected, the air flow is ejected to the surrounding areas through the air flow injection port 183, blowing the raw materials near the air flow cover 182 away from its own position. At the same time, the air flow injection port 183 will drive the air flow cover 182 to rotate, and finally the raw materials are mixed. After the near-infrared sensor detects that the mixing is sufficient, the feeding operation of the mixing box 12 is completed through the discharge control part 111. When the air flow no longer enters the equalizing bin 19, the air flow cover 182 will automatically fall to block the air outlet.

[0064] Among them, Figure 2 、 7 As shown, the discharging control component 111 includes a discharging cylinder 1111 and a discharging barrel 1112. The discharging cylinder 1111 is installed at the bottom of the flow equalizing bin 19. The output end of the discharging cylinder 1111 is connected to the discharging barrel 1112 through a connecting plate. The discharging barrel 1112 slides in the flow equalizing bin 19 and the inlet and outlet. The top of the discharging barrel 1112 passes through the inlet and outlet and is connected to a material blocking head 1113. The top side wall of the discharging barrel 1112 is provided with a discharging portion.

[0065] When feeding is required after mixing is completed, the discharge cylinder 1111 drives the discharge barrel 1112 upward, and the blocking head 1113 moves upward, exposing the discharge part at the same time, and the mixed raw materials are discharged from the inside and outside of the discharge part for feeding.

[0066] Example 3

[0067] like Figure 2 、 6 As shown, in the feeding device, in order to complete the addition and adjustment of the mixing amount of different raw materials, a feeding box 14 is provided between the collecting hopper 13 and the mixing box 12, and a switch valve plate 15 is provided between the feeding box 14 and the collecting hopper 13 and the mixing box 12. The top side of the feeding box 14 is connected to the collecting hopper 13, and the bottom side is connected to the mixing box 12;

[0068] A space control plate 141 and a feeding plate 142 are installed in the feeding box 14. The space control plate 141 slides in the feeding box 14 and a threaded lifting rod 143 is installed on the top. The threaded lifting rod 143 is threadedly fitted on the top of the feeding box 14 and rotatably installed on the space control plate 141 at the bottom. The threaded lifting rod 143 is used to adjust the height of the space control plate 141. A lifting cylinder 144 is installed at the bottom of the feeding box 14. The piston rod of the lifting cylinder 144 enters the feeding box 14 and is connected to the feeding plate 142. The feeding plate 142 slides inside the feeding box 14. The height of the feed port of the feeding box 14 is greater than the height of the discharge port.

[0069] By rotating the threaded lifting rod 143, the upper and lower positions of the space control plate 141 are adjusted, and then the space size of the loading box 14 is adjusted. In conjunction with the two switch valve plates 15, the loading box 14 can be automatically quantitatively filled. The top surface of the feeding plate 142 and the bottom surface of the space control plate 141 are both inclined downward to facilitate filling and discharging. In conjunction with the lifting cylinder 144, the two switch valve plates 15 are coordinated to control the raw material adding operation in the loading box 14.

[0070] Example 4

[0071] In the feeding device, Figure 9 、 10 As shown, the grab bag structure includes a mounting plate 231, and two groups of thorn bag parts 232 are rotatably installed on the side of the mounting plate 231 facing away from the grab bag chain 23 along the running direction of the grab bag chain 23. The bottom of the thorn bag part 232 is provided with a thorn bag body, and a contact frame 233 is installed on the outside of the thorn bag part 232. Connecting ear plates 234 are respectively installed on both sides of the top of the contact frame 233. The connecting ear plates 234 slide vertically with the mounting plate 231 through the guide rod. The two connecting ear plates 234 are arranged along the running direction of the grab bag chain 23, and the side of the contact frame 233 is provided with a guide groove 235 perpendicular to the running direction of the grab bag chain 23. Two groups of moving blocks 236 and spring parts 238 fixed on the moving blocks 236 at both ends are slidably fitted in the guide groove 235. The moving block 236 is connected to the body of the thorn bag part 232 through a connecting pin 237. A constraint is installed on the side of the contact frame 233, which is used to selectively limit the reset of the moving block 236.

[0072] During the operation of the bag-grabbing chain 23, the thorns at the bottom of the bag-grabbing element 232 puncture the bag. Subsequently, the contact frame 233 gradually contacts the bag and is blocked from moving upward relative to the bag. Simultaneously, the thorns 232 are driven toward each other via the connecting pin 237. As they approach, the moving block 236 compresses the spring element 238. The restraining member restricts the moving block 236 from moving in the opposite direction, thereby maintaining the thorns 232 in this position and firmly grasping the bag. It should be noted that when the contact frame 233 is located above the mounting plate 231, the spring element 238 does not undergo any elastic deformation.

[0073] Among them, Figure 11 As shown, the restraining member includes a one-way stop plate 239 and a fixed plate 2310. The one-way stop plate 239 is distributed above the moving block 236. A vertical rod 2311 is installed on the top of the one-way stop plate 239. The vertical rod 2311 is slidably fitted on the fixed plate 2310. The fixed plate 2310 is fixed to the outer wall of the contact frame 233. An elastic member is sleeved on the outer side of the vertical rod 2311 between the fixed plate 2310 and the one-way stop plate 239. The top of the one-way stop plate 239 and the moving block 236 are both ratchet structures.

[0074] A side plate 2312 is mounted on the outer wall of the contact frame 233. The side plate 2312 and the connecting ear plate 234 are located on the same side and are arranged perpendicular to the connecting ear plate 234. A sliding rod 2313 is slidably engaged with the side plate 2312. One end of the sliding rod 2313 is connected to the fixed plate 2310 and the one-way stop plate 239 via a connecting rope. The other end of the sliding rod 2313 is provided with a wedge block 2314.

[0075] like Figure 8 、 15 As shown, the loosening structure includes an outer top block 2315, which is a wedge-shaped structure used to move the wedge block 2314 outward. The outer top block 2315 and the wedge block 2314 are located at the same horizontal height and the wedge block 2314 passes through the outer top block 2315.

[0076] As the bag grabbing chain 23 continues to operate, the raw materials in the bag fall into the collecting hopper 13. The bag piercing member 232 only grabs the bag, and along the way, the wedge block 2314 moves outward through the outer top block 2315, releasing the restraint state of the moving block 236. The moving block 236 is reset under the action of the spring member 238, and the bag piercing member 232 is automatically reset and separated from the bag.

[0077] Example 5

[0078] In Example 4, in order to ensure that the bag-piercing member 232 still has sufficient conveying power after the bag is separated from the conveyor chain 21, the following improvements are made:

[0079] like Figure 12 、 13As shown, the thorn bag member 232 includes a rotating part 2321, and the rotating part 2321 is composed of an oblique body, a curved body and a vertical body from top to bottom. The two vertical bodies are installed with anchoring through-holes on the facing sides, and the two vertical bodies are provided with mounting grooves 2320 on the back-facing sides. A vertically sliding driving block 2319 and a constraint plate located at the slot are installed in the mounting groove 2320. The constraint plate is used to constrain the driving block 2319 to the left and right. An elastic member is installed between the top of the driving block 2319 and the mounting groove 2320. Driving curved surfaces are evenly distributed on the driving block 2319, and a ball head body is adapted to be provided at the driving curved surface. An anchor head body 2318 is installed at the end of the ball head body facing away from the driving block 2319. The anchor head body 2318 is inserted into the anchoring through-hole, and a spring is provided on the anchor head body 2318 between the ball head body and the anchoring through-hole.

[0080] like Figure 12 As shown, the connecting pin 237 is rotatably installed on the oblique body, and both ends are respectively fixed on the corresponding moving blocks 236. A winding disk 2316 is provided on the connecting pin 237, and a notch is provided on the oblique body. The notch is used to install the winding disk 2316, and a rope body 2317 is wound around the winding disk 2316. One end of the rope body 2317 freely enters the installation groove 2320 and is connected to the top of the driving block 2319; the thorn bag body is located at the bottom of the vertical body.

[0081] In practice, after the bag-piercing member 232 enters the bag, the bottom of the rotating portion 2321 rotates upward relative to the connecting pin 237 by a certain angle, causing the winding disk 2316 to wind a certain length of rope 2317. Rope 2317 then drives the driving block 2319 upward, overcoming the force of the elastic member. The driving curved surface squeezes the ball head body, which in turn squeezes the elastic member outside. When the ball head body moves to the vertical plane between the two driving curved surfaces on the driving block 2319, the anchor head body 2318 is extended to grasp the bag and prevent it from accidentally falling. At this time, the elastic member acts directly perpendicularly on the ball head body on the vertical plane, ensuring the stability of the anchor head body 2318. In this state, the movable block 236 is prevented from moving in the opposite direction due to the action of the restraining member, thereby maintaining the stability of the rotating portion 2321 and the anchor head body 2318. When the restraining member releases the restraining conditions on the moving block 236, the contact frame 233 will fall, the rotating part 2321 will rotate in the opposite direction relative to the mounting plate 2316, and the driving block 2319 will complete the reset under the action of the elastic member. During this process, when the ball head body enters the driving curved surface area, under the action of the elastic body, the anchor head body 2318 also returns to the vertical body.

[0082] Example 6

[0083] In Example 5, Figure 8As shown, a bag recovery box 30 is mounted on the top frame 20. The bag recovery box 30 is provided with a bag grabbing inlet and outlet, a gripping release mechanism is mounted on the sidewall of the bag grabbing inlet and outlet, and a bag discharge port is mounted at the bottom of the bag recovery box 30. After entering the bag grabbing inlet and outlet, the gripping release mechanism automatically lowers the bag into the bag recovery box 30 and ultimately discharges the bag discharge port for unified processing.

[0084] A feeding method for high-freshness meat cat food, using the feeding device, comprises the following steps:

[0085] Step 1: Loading raw materials

[0086] Each raw material bag is grabbed by a manipulator and placed on the conveyor chain 21. The conveyor chain 21 conveys the raw material bag to the collecting hopper 13. During the conveying period, the grab bag structure on the grab bag chain 23 grabs the raw material bag and cooperates with the conveyor chain 21 to pass the raw material bag through the bag cutting part 22. The bottom of the raw material bag is cut by the bag cutting part 22. At this time, the grab bag structure is still in the state of grabbing the raw material bag. The grab bag structure puts the raw material bag into the grab bag inlet and outlet and the grab bag structure releases the raw material bag by the action of the loose grip structure. The raw material bag and the grab bag structure are separated and finally discharged from the bag outlet.

[0087] Step 2: quantitative discharge

[0088] The raw materials enter the collecting hopper 13 from the cut raw material bag, and the side top switch valve plate 15 of the feeding box 14 is adjusted to be in the open state and the side bottom switch valve plate 15 is in the closed state. The raw materials in the collecting hopper 13 fill the feeding box 14, and then the side top switch valve plate 15 of the feeding box 14 is adjusted to be in the closed state and the side bottom switch valve plate 15 is in the open state. A space control plate 141 and a feeding plate 142 are provided inside the feeding box 14. The space control plate 141 is used to control the size of the space in the feeding box 14, and the feeding plate 142 sends out the raw materials in the feeding box 14 under the action of the lifting cylinder 144;

[0089] Step 3, Mix

[0090] The raw materials are quantitatively fed into the mixing box 12, and an external air flow supply device delivers high-pressure air into the flow equalization chamber 19. At the same time, the servo motor 110 drives the air flow disk 17 to rotate through a gear transmission at a speed of 1-2 revolutions per second. The high-pressure air flows through the air outlet 181 into the air flow cover 182 and is ejected to the surroundings through the air flow injection port 183 to mix the raw materials.

[0091] Step 4: Add materials

[0092] After the near-infrared sensor detects that the mixture is uniform, the discharge cylinder 1111 drives the discharge barrel 1112 upward through the connecting plate, and the blocking head 1113 moves upward. The uniformly mixed raw materials are discharged from the mixing box 12 through the discharge part through the discharge barrel 1112 for feeding operation.

[0093] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. The replacement may be a replacement of a portion of a structure, device, or method step, or it may be a complete technical solution. Any equivalent replacement or modification based on the technical solution and inventive concept of the present invention shall be covered by the scope of protection of the present invention.
