As people's love for pet cats increases, freeze-dried cat food has appeared on the market to ensure the nutritional value of cat food.

[0003] At present, when freeze-dried cat food products are produced, the freeze-dried raw materials need to be crushed first, and then the crushed freeze-dried raw materials are poured into an extruder so that the freeze-dried raw materials can be extruded and formed under the action of the extruder. That is to say, when freeze-dried cat food products are produced, different processes need to be completed in at least two devices, which affects the production efficiency of the freeze-dried cat food products and increases the workload of the staff. Utility Model Content

[0007] By adopting the above technical solution, when producing freeze-dried cat food products, the driving member is started so that the driving member drives the crushing knife to rotate, and then the raw materials are poured into the crushing box, and the rotating crushing knife crushes the raw materials. The crushed raw materials enter the extrusion tube, and the power member is started. The power member drives the pressure member, and then the crushed raw materials in the extrusion tube are extruded through the extrusion port under the action of the pressure member to complete the production of the freeze-dried cat food products. In this process, the need to process the freeze-dried cat food products in at least two devices is avoided, thereby improving the production efficiency of the freeze-dried cat food products, and at the same time, the need for staff to transport the crushed raw materials is avoided, thereby reducing the workload of the staff.

[0008] Optionally, an extrusion die is detachably connected to the extrusion port, and the extrusion die has a molding channel, so that the raw material located inside the extrusion tube can be extruded through the molding channel under the action of the pressure member.

[0009] By adopting the above technical solution, the crushed raw material inside the extrusion tube enters the molding channel under the action of the pressure member, so that the crushed raw material is extruded through the molding channel to obtain the desired size or shape, and the extrusion die is detachably connected to the extrusion port, so that the extrusion die can be replaced, so that the freeze-dried cat food product raw material extruder can produce a variety of products, thereby improving the flexibility of the freeze-dried cat food product raw material extruder.

[0010] Optionally, the extrusion tube is threadedly connected to a limit ring located at one end of the extrusion port, and the limit ring has a stop portion that cooperates with the extrusion die stopper.

[0011] By adopting the above technical solution, when replacing the extrusion die, the limiting ring is separated from the extrusion tube so that the stop part is separated from the extrusion die, and then the extrusion die is taken out from the extrusion port, and then the required extrusion die is installed in the extrusion port, and finally the limiting ring is threadedly connected to the extrusion tube so that the stop part cooperates with the extrusion die stopper to complete the replacement of the extrusion die. In this process, it is only necessary to rotate the limiting ring, thereby reducing the difficulty of replacing the extrusion die and increasing the connection stability between the extrusion die and the extrusion tube.

[0012] Optionally, a cutting knife and an actuator are provided at one end of the crushing box, the cutting knife abuts against the extrusion die, and the actuator is used to drive the cutting knife to rotate so that the cutting knife cuts the raw material extruded through the forming channel.

[0013] By adopting the above technical solution, when the crushed raw material in the extrusion tube is extruded through the forming channel under the action of the pressure member, the actuator drives the cutting knife to rotate the cutting knife, and then the cutting knife cuts the raw material extruded through the forming channel, thereby shortening the raw material extruded through the forming channel, so as to achieve the cutting of the raw material extruded through the forming channel, avoiding the need to use other equipment to cut the raw material in the later stage, and further improving the production efficiency of freeze-dried cat food products.

[0014] Optionally, extension plates are extended on both sides of the crushing box, the actuator is arranged on the mounting plate, the mounting plate has a connecting end and a swinging end opposite to the connecting end, the connecting end is hinged to one of the extension plates, and the swinging end is detachably connected to the other extension plate.

[0015] By adopting the above technical solution, when replacing the extrusion die, the extension plate corresponding to the swing end is first separated, and then the mounting plate is rotated, and then the mounting plate drives the actuator and the cutting knife to move, so that the cutting knife is separated from the extrusion die, and then the extrusion die can be replaced, thereby ensuring the effect of facilitating the replacement of the extrusion die.

[0016] Optionally, a locking hole is provided at the swing end, and a locking rod is slidably connected to the extension plate corresponding to the locking hole, and the locking rod has a locking position passing through the locking hole and an unlocking position separated from the locking hole.

[0017] By adopting the above technical solution, when replacing the extrusion die, the locking rod is first slid to move the locking rod from the locking position to the unlocking position, and then the mounting plate is rotated. After the extrusion die is replaced, the mounting plate is rotated in the opposite direction to align the locking rod with the locking hole, and then the locking rod is operated to move the locking rod from the unlocking position to the locking position to achieve locking of the swing end. In the process of locking or unlocking the mounting plate, it is only necessary to slide the locking rod, thereby reducing the difficulty of locking or unlocking the mounting plate, thereby improving the replacement efficiency of the extrusion die.

[0018] Optionally, the extension plate corresponding to the swing end is provided with a connecting tube, the locking rod is passed through the connecting tube, and the locking rod is provided with an elastic member. When the locking rod is in the unlocking position, the elastic member is deformed and applies an elastic force to the locking rod to move toward the locking position.

[0019] By adopting the above technical solution, when the mounting plate is unlocked, the locking rod is pulled so that the locking rod applies pressure to the elastic member, which then causes the elastic member to deform so that the locking rod moves from the locking position to the unlocking position, thereby unlocking the mounting plate. By setting the elastic member, the locking rod needs to overcome the elastic force of the elastic member when moving from the locking position to the unlocking position, so as to increase the force required for the locking rod to move to the unlocking position, thereby increasing the stability of the locked mounting plate, so as to ensure the safety of the freeze-dried cat food product raw material extruder during operation.

[0020] Optionally, a guide surface is provided on one side of the locking rod that caters to the mounting plate, and the guide surface can cooperate with the mounting plate so that when the mounting plate contacts the guide surface and is subjected to pressure in the direction of the locking rod, the locking rod moves along its own axial direction away from the mounting plate under the action of the guide surface.

[0021] By adopting the above technical scheme, when locking the mounting plate, the mounting plate is first rotated in the direction of the guide surface so that the mounting plate is in contact with the guide surface, and then pressure is applied to the mounting plate so that the mounting plate applies pressure to the guide surface, and then the locking rod moves along its own axial direction in the direction away from the mounting plate under the action of the guide surface, so that the locking rod and the mounting plate form an avoidance, that is, the locking rod moves from the locked state to the unlocked state, and at the same time the locking rod overcomes the elastic force of the elastic member, and when the mounting plate moves into place, that is, after the locking hole is aligned with the locking rod, the locking rod extends into the locking hole under the action of the elastic member to complete the locking of the mounting plate. In this process, the need for manual operation of the locking rod is avoided, thereby achieving the effect of facilitating the locking of the mounting plate.

[0022] Optionally, the extrusion die has a positioning cavity, and the cutting knife has a positioning shaft extending into the positioning cavity.

[0023] By adopting the above technical solution, when the cutting knife rotates under the action of the actuator, the cutting knife drives the positioning shaft to rotate, and the positioning shaft and the positioning cavity rotate relative to each other, so that the cooperation between the positioning shaft and the positioning cavity can support the cutting knife, so as to avoid the cutting knife from deflecting under the action of centrifugal force when rotating, so as to increase the safety of the cutting knife when rotating, and further increase the safety of the raw material extruder of freeze-dried cat food products.

[0024] Optionally, the actuator has a rotating shaft, the rotating shaft has a accommodating cavity, the cutting knife has a connecting shaft extending into the accommodating cavity, the accommodating cavity is provided with a resetting member acting on the connecting shaft and having elasticity, the rotating shaft is provided with a waist-shaped groove communicating with the accommodating cavity, and the connecting shaft is provided with a limiting shaft passing through the waist-shaped groove.

[0025] By adopting the above technical solution, when locking the mounting plate, the mounting plate is first rotated in the direction close to the locking rod. When the mounting plate is about to contact the guide surface, pressure is applied to the limit shaft in the direction of the mounting plate to make the limit shaft and the waist groove slide relative to each other. At the same time, the limit shaft drives the connecting shaft to move, and the connecting shaft applies pressure to the reset member, and the reset member undergoes elastic deformation to make the cutting tool and the extrusion die avoid each other. Then, the mounting plate is continued to be pressed to make the locking rod lock the mounting plate. At this time, the positioning shaft is aligned with the accommodating cavity, and then the limit shaft is released. The connecting shaft moves in the direction away from the mounting plate under the action of the reset member, so that the positioning shaft extends into the positioning cavity. In this process, the situation in which the positioning shaft and the extrusion die interfere with each other and affect the locking of the mounting plate is avoided, thereby reducing the difficulty of locking the mounting plate.

[0026] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

The crushed raw materials enter the extrusion tube 31, and the power member 33 is started. The power member 33 drives the pressure member 32, and then the crushed raw materials in the extrusion tube 31 are extruded through the extrusion port under the action of the pressure member 32 to complete the production of the freeze-dried cat food products. In this process, the need to process the freeze-dried cat food products in at least two devices is avoided, thereby improving the production efficiency of the freeze-dried cat food products, and at the same time, the need for staff to transport the crushed raw materials is avoided, thereby reducing the workload of the staff.

[0052] The present application does not specifically limit the structure of the driving member 22. Preferably, refer to Figure 1 The driving member 22 is a driving motor disposed outside the crushing box 1, and the crushing knife 21 is provided with a transmission shaft. The output shaft of the driving motor is in transmission connection with the transmission shaft to drive the crushing knife 21 to crush the raw materials in the crushing box 1. In other embodiments, the driving member 22 can also be a pneumatic motor.

[0053] The present application does not specifically limit the structures of the pressure member 32 and the power member 33. Preferably, refer to Figure 1 and Figure 6 , the pressure member 32 is a screw conveying rod rotatably connected to the inside of the extrusion tube 31, and the power member 33 is a driving motor provided at the end of the extrusion tube 31 away from the extrusion port. The output shaft of the driving motor is drivingly connected to the screw conveying rod to drive the screw conveying rod to rotate, so that the screw conveying rod conveys the raw materials in the extrusion tube 31 toward the extrusion port.

The power member 33 is any one of a cylinder, a hydraulic cylinder or an electric push rod provided at the end of the extrusion tube 31 away from the extrusion port. The piston rod of the power member 33 is connected to the pressure rod to drive the pressure rod to move, so that the pressure plate pushes the raw materials in the extrusion tube toward the extrusion port.

[0054] The present application does not specifically limit the extrusion method of the raw material through the extrusion port. Preferably, refer to Figure 2 and Figure 3 An extrusion die 311 is detachably connected to the extrusion port, and a molding channel 312 is provided on the extrusion die 311 so that the raw material inside the extrusion tube 31 can be extruded through the molding channel 312 under the action of the pressure member 32 .

[0055] The crushed raw material inside the extrusion tube 31 enters the forming channel 312 under the action of the pressure member 32, so that the crushed raw material is extruded through the forming channel 312 to obtain the desired size or shape, and the extrusion die 311 is detachably connected to the extrusion port, so that the extrusion die 311 can be replaced, so that the freeze-dried cat food product raw material extruder can produce a variety of products, so as to improve the flexibility of the freeze-dried cat food product raw material extruder.

[0056] The present application does not specifically limit the detachable connection method between the extrusion die 311 and the extrusion tube 31. Preferably, refer to Figure 2 and Figure 4 The extrusion tube 31 is threadedly connected with a limiting ring 314 located at one end of the extrusion port, and the limiting ring 314 has a stopping portion 315 that cooperates with the extrusion die 311 to stop.

[0057] When replacing the extrusion die 311, the limiting ring 314 is separated from the extrusion tube 31 so that the stop portion 315 is separated from the extrusion die 311, and then the extrusion die 311 is taken out from the extrusion port, and then the required extrusion die 311 is installed in the extrusion port, and finally the limiting ring 314 is threadedly connected to the extrusion tube 31 so that the stop portion 315 cooperates with the extrusion die 311 stop to complete the replacement of the extrusion die 311. In this process, it is only necessary to rotate the limiting ring 314, thereby reducing the difficulty of replacing the extrusion die 311 and increasing the connection stability between the extrusion die 311 and the extrusion tube 31.

[0058] The present application does not specifically limit the structure of the stopper 315. Preferably, refer to Figure 4 The stopper 315 is an annular structure to increase the stopper matching area with the extrusion die 311, thereby increasing the stability of the extrusion die 311. In other implementation examples, the stopper 315 can also be a plurality of block structures arranged at intervals along the circumference of the limiting ring 314.

[0059] In other embodiments, the extrusion die 311 may also be detachably connected to the extrusion tube 31 via screws, that is, the extrusion tube 31 is provided with screws penetrating the extrusion die 311 .

[0060] In a preferred embodiment, referring to Figure 2 and Figure 8 A cutting knife 4 and an actuator 5 are provided at one end of the crushing box 1 . The cutting knife 4 abuts against the extrusion die 311 . The actuator 5 is used to drive the cutting knife 4 to rotate so that the cutting knife 4 cuts the raw material extruded through the forming channel 312 .

[0061] When the crushed raw material in the extrusion tube 31 is extruded through the forming channel 312 under the action of the pressure member 32, the actuator 5 drives the cutting knife 4 to rotate the cutting knife 4, and then the cutting knife 4 cuts the raw material extruded through the forming channel 312, thereby shortening the raw material extruded through the forming channel 312, so as to achieve the cutting of the raw material extruded through the forming channel 312, avoiding the need to use other equipment to cut the raw material in the later stage, and further improving the production efficiency of freeze-dried cat food products.

[0062] Further, see Figure 1 , Figure 2 , Figure 6 and Figure 7 Extension plates 111 are extended on both sides of the crushing box 1, the actuator 5 is arranged on the mounting plate 51, the mounting plate 51 has a connecting end and a swinging end opposite to the connecting end, the connecting end is hinged to one of the extension plates 111, and the swinging end is detachably connected to the other extension plate 111.

[0063] Specifically, a support leg 11 is disposed at the bottom of the crushing box 1 , and an extension plate 111 is disposed on the support leg 11 , and the extension plate 111 is extended from the support leg 11 toward a direction away from the crushing box 1 .

[0064] When replacing the extrusion die 311, first separate the swing end from the corresponding extension plate 111, and then rotate the mounting plate 51, so that the mounting plate 51 drives the actuator 5 and the cutting knife 4 to move, thereby separating the cutting knife 4 from the extrusion die 311, and then replace the extrusion die 311, thereby ensuring the effect of facilitating the replacement of the extrusion die 311.

[0065] Further, refer to Figure 2 , Figure 5 , Figure 6 and Figure 7 A locking hole 511 is provided at the swing end, and a locking rod 12 is slidably connected to the extension plate 111 corresponding to the locking hole 511. The locking rod 12 has a locking position penetrating through the locking hole 511 and an unlocking position separated from the locking hole 511.

[0066] When replacing the extrusion die 311, first slide the locking rod 12 to move the locking rod 12 from the locked position to the unlocked position, and then rotate the mounting plate 51. After the extrusion die 311 is replaced, rotate the mounting plate 51 in the opposite direction to align the locking rod 12 with the locking hole 511, and then operate the locking rod 12 to move the locking rod 12 from the unlocked position to the locked position to achieve locking of the swing end. In the process of locking or unlocking the mounting plate 51, it is only necessary to slide the locking rod 12, thereby reducing the difficulty of locking or unlocking the mounting plate 51, thereby improving the replacement efficiency of the extrusion die 311.

[0067] Further, see Figure 2 , Figure 5 , Figure 6 and Figure 7 The extension plate 111 corresponding to the swing end is provided with a connecting tube 13, the locking rod 12 is passed through the connecting tube 13, and the locking rod 12 is provided with an elastic member 14. When the locking rod 12 is in the unlocking position, the elastic member 14 is deformed and applies an elastic force to the locking rod 12 to move toward the locking position.

[0068] When the mounting plate 51 is unlocked, the locking rod 12 is pulled so that the locking rod 12 applies pressure to the elastic member 14, which then deforms the elastic member 14 so that the locking rod 12 moves from the locked position to the unlocked position, thereby unlocking the mounting plate 51. By setting the elastic member 14, the elastic force of the elastic member 14 needs to be overcome when the locking rod 12 moves from the locked position to the unlocked position, so as to increase the force required for the locking rod 12 to move to the unlocked position, thereby increasing the stability of the locking of the mounting plate 51, so as to ensure the safety of the freeze-dried cat food product raw material extruder during operation.

[0069] The present application does not specifically limit the structure of the elastic member 14. Preferably, refer to Figure 5 The elastic member 14 is a spring sleeved outside the locking rod 12 to increase the elastic force that the elastic member 14 can apply to the locking rod 12. In other implementation examples, the elastic member 14 can also be an elastic sheet.

[0070] Specifically, refer to Figure 5 The locking rod 12 has a locking section 121 and a connecting section 122. The diameter of the locking section 121 is larger than the diameter of the connecting section 122. The top of the connecting tube 13 has a blocking rib extending into the interior of the connecting tube 13. The elastic member 14 is sleeved on the connecting section 122, and one end of the elastic member 14 abuts against the end of the locking section 121, and the other end of the elastic member 14 abuts against the blocking rib. A blocking sheet 124 is provided at one end of the connecting section 122 away from the locking section 121. The blocking sheet 124 can cooperate with the top end surface stop of the connecting section 122 to limit the locking rod 12 and prevent the locking rod 12 from separating from the connecting tube 13.

[0071] Better, refer to Figure 2 and Figure 5 A pull ring 125 is provided on the top of the blocking piece 124 to facilitate the staff to pull the locking rod 12 from the locking position to the unlocking position.

[0072] Further, refer to Figure 5 and Figure 7 A guide surface 123 is provided on one side of the locking rod 12 that caters to the mounting plate 51. The guide surface 123 can cooperate with the mounting plate 51 so that when the mounting plate 51 contacts the guide surface 123 and is subjected to pressure in the direction of the locking rod 12, the locking rod 12 moves along its own axial direction in a direction away from the mounting plate 51 under the action of the guide surface 123.

[0073] That is to say, the guide surface 123 is provided on the locking section 121. When the mounting plate 51 is locked, the mounting plate 51 is first rotated in the direction of the guide surface 123 so that the mounting plate 51 contacts the guide surface 123, and then pressure is applied to the mounting plate 51 so that the mounting plate 51 applies pressure to the guide surface 123, and then the locking rod 12 is moved along its own axial direction in the direction away from the mounting plate 51 under the action of the guide surface 123, so that the locking rod 12 and the mounting plate 51 form a avoidance, that is, the locking rod 12 moves from the locked state to the unlocked state, and at the same time, the locking rod 12 overcomes the elastic force of the elastic member 14, and when the mounting plate 51 moves into place, that is, after the locking hole 511 is aligned with the locking rod 12, the locking rod 12 extends into the locking hole 511 under the action of the elastic member 14 to complete the locking of the mounting plate 51. In this process, the need for manual operation of the locking rod 12 is avoided, thereby achieving the effect of facilitating the locking of the mounting plate 51.

[0074] The present application does not specifically limit the number of locking rods 12. Preferably, refer to Figure 2 and Figure 7 There are two locking rods 12, and two connecting tubes 13 and elastic members 14 are provided corresponding to the locking rods 12, and the two locking rods 12 are respectively located at the top and bottom of the mounting plate 51 to increase the locking points of the mounting plate 51, thereby increasing the stability of the mounting plate 51.

[0075] In a preferred embodiment, referring to Figure 3 and Figure 8 The extrusion die 311 has a positioning cavity 313 , and the cutting knife 4 has a positioning shaft 41 extending into the positioning cavity 313 .

[0076] Specifically, the central axis of the positioning cavity 313 is colinearly arranged with the central axis of the extrusion die 311 , and the central axis of the positioning shaft 41 is colinearly arranged with the rotation axis of the cutting blade 4 .

[0077] When the cutting knife 4 rotates under the action of the actuator 5, the cutting knife 4 drives the positioning shaft 41 to rotate, and the positioning shaft 41 and the positioning cavity 313 rotate relative to each other, so that the cooperation between the positioning shaft 41 and the positioning cavity 313 can support the cutting knife 4, so as to avoid the cutting knife 4 from deflecting under the action of centrifugal force when rotating, so as to increase the safety of the cutting knife 4 when rotating, and further increase the safety of the raw material extruder of the freeze-dried cat food product.

[0078] Further, see Figure 1 and Figure 8The actuator 5 has a rotating shaft, the rotating shaft has a accommodating cavity 52, the cutting knife 4 has a connecting shaft 42 extending into the accommodating cavity 52, a resetting member 522 with elasticity acting on the connecting shaft 42 is arranged in the accommodating cavity 52, the rotating shaft is provided with a waist-shaped groove 521 communicating with the accommodating cavity 52, and the connecting shaft 42 is provided with a limiting shaft 421 penetrating the waist-shaped groove 521.

[0079] Specifically, the length direction of the waist-shaped groove 521 is arranged parallel to the axial direction of the rotating shaft, and both ends of the limiting shaft 421 protrude from the circumferential surface of the rotating shaft through the waist-shaped groove 521 .

[0080] When locking the mounting plate 51, the mounting plate 51 is first rotated toward the direction close to the locking rod 12. When the mounting plate 51 is about to contact the guide surface 123, pressure is applied to the limit shaft 421 in the direction of the mounting plate 51, so that the limit shaft 421 and the waist groove 521 slide relative to each other. At the same time, the limit shaft 421 drives the connecting shaft 42 to move, and the connecting shaft 42 applies pressure to the reset member 522, and the reset member 522 is elastically deformed, so that the cutting tool 4 and the extrusion die 311 form an avoidance. , and then continue to press the mounting plate 51 so that the locking rod 12 locks the mounting plate 51. At this time, the positioning shaft 41 is aligned with the accommodating cavity 52, and then the limiting shaft 421 is released. The connecting shaft 42 moves in a direction away from the mounting plate 51 under the action of the reset member 522, so that the positioning shaft 41 extends into the positioning cavity 313. In this process, the mutual interference between the positioning shaft 41 and the extrusion die 311 is avoided to affect the locking of the mounting plate 51, thereby reducing the difficulty of locking the mounting plate 51.

[0081] The present application does not specifically limit the structure of the actuator 5. Preferably, refer to Figure 1 , Figure 2 , Figure 6 and Figure 8 , the actuator 5 is a driving motor, and the rotating shaft is the output shaft of the driving member 22. In other implementation examples, the actuator 5 may also be a pneumatic motor.

[0082] The present application does not specifically limit the structure of the reset member 522. Preferably, refer to Figure 8 The reset member 522 is a spring disposed in the accommodating chamber 52, and the two ends of the spring respectively contact the connecting shaft 42 and the cavity wall of the accommodating chamber 52. In other implementation examples, the reset member 522 can also be an elastic sheet, an elastic sleeve, or other elastic structures.

[0083] In other embodiments, multiple extrusion ports may be provided, that is, the end of the extrusion tube 31 is closed, and multiple extrusion ports are provided at the end of the extrusion tube 31 to reduce the production cost of the freeze-dried cat food product raw material extruder.
