Description

Technical Field

[0001] The present application belongs to the technical field of pet food production, and in particular relates to a semi-dry pet food extruder. Background Art

[0002] Pet food is food specially provided for pets and small animals. It is a high-end animal food between human food and traditional poultry feed. Its main function is to provide pets with the most basic nutrients needed for life support, growth and health. It has the advantages of comprehensive nutrition, high digestion and absorption rate, scientific formula, convenient feeding and prevention of certain diseases. When producing semi-dry pet food, extrusion equipment is needed to extrude the raw materials so that the raw materials can be formed into the required shape.

[0003] At present, common extrusion equipment is divided into two types, namely horizontal extruder and vertical extruder. Since the horizontal extruder has the defect of occupying a large area, while the vertical extruder requires a small area, the vertical extruder is gradually promoted and applied.

[0004] In order to facilitate the workers to receive the extruded food, the existing extruders generally have a workbench so that the discharge port of the extruder is at a certain distance from the ground, so that the workers can receive the extruded food. However, since the bottom of the extruder has a workbench, the feed port of the extruder is at a higher position, so that the workers need to use a ladder or a high stool to invert the raw materials into the extruder, which affects the production efficiency of pet food and increases the safety hazards of the extruder. Utility Model Content

[0005] The present application provides a semi-dry pet food extruder to improve the production efficiency of pet food and eliminate the potential safety hazards of the extruder.

[0006] The technical solution adopted in this application is:

[0007] A semi-dry pet food extruder comprises a workbench, a raw material tank arranged on the top of the workbench, and a pressurizing assembly arranged on the top of the workbench, the raw material tank being connected to an extrusion tube, the pressurizing assembly comprising a driving member and a pressurizing plate capable of moving into the interior of the raw material tank, the driving member being used to drive the pressurizing plate to move so that the pressurizing plate extrude the raw material and extrude it through the extrusion tube, the top end face of the workbench having a center hole for the raw material tank to pass through, the raw material tank being movably connected to a locking member, the locking member having an avoidance position for avoiding the center hole and a locking position for cooperating with a stopper on the top end face of the workbench.

[0008] By adopting the above technical scheme, when using the semi-dry pet food extruder in the present application, the locking member is first operated to rotate the locking member from the locking position to the avoidance position, and then the locking member and the center hole form an avoidance, and the raw material tank descends under the action of its own gravity, and then the feed port of the raw material tank descends, and then the raw material is poured into the raw material tank, and then the raw material tank is driven upward, so that the raw material tank moves to the top of the workbench, and then the locking member is operated in reverse to make the locking member cooperate with the top end surface stop of the workbench, so that the table surface of the workbench supports the raw material tank, and then the driving member is started, and the driving member drives the pressure plate to make the pressure plate squeeze the raw material in the raw material tank, and the extruded raw material is extruded through the extrusion tube and formed into a desired shape.

[0009] In summary, when loading the semi-dry pet food extruder in the present application, the feed port of the raw material tank can be adjusted to a lower position so that the staff can invert the raw materials into the raw material tank, thereby improving the production efficiency of pet food and avoiding the need for staff to use ladders or climbing stools, thereby eliminating the safety hazards of the semi-dry pet food extruder.

[0010] Optionally, the locking member includes a turntable rotatably connected to the raw material tank and a locking block arranged on the circumferential side of the turntable, and the hole wall of the center hole is provided with an avoidance groove corresponding to the locking block, and when the locking block is in the avoidance position, the locking block and the avoidance groove are arranged opposite to each other in the vertical direction.

[0011] By adopting the above technical solution, when inverting the raw materials into the raw material tank, first rotate the turntable to make the turntable drive the locking block to move, and then make the locking block move to a position opposite to the avoidance groove, so that the raw material tank and the turntable slide downward through the center hole, so that the feed port of the raw material tank is in a lower position; and after pushing the raw material tank upward so that the raw material tank is located above the workbench, rotate the turntable in the opposite direction, and then rotate the locking block to a position misaligned with the avoidance groove, and at the same time, the locking block contacts the top end surface of the workbench, so that the locking block and the turntable support the raw material tank.

[0012] During the operation of the locking member, only the turntable needs to be rotated, thereby reducing the difficulty of operating the locking member, thereby further improving the efficiency of inverting the raw materials into the raw material tank, and further improving the production efficiency of pet food. In addition, the turntable can also strengthen the bottom wall of the raw material tank to increase the structural strength of the raw material tank, thereby increasing the service life of the raw material tank.

[0013] Optionally, a plurality of locking blocks are arranged at intervals along the circumference of the turntable, and a plurality of avoidance grooves are arranged corresponding to the locking blocks.

[0014] By adopting the above technical solution, since multiple locking blocks are arranged at intervals along the circumference of the turntable, the stopper matching points between the locking member and the top end surface of the workbench are increased, thereby increasing the support stability of the raw material tank, thereby ensuring the normal operation of the semi-dry pet food extruder. At the same time, the provision of multiple locking blocks and multiple avoidance grooves can reduce the required rotation angle of the locking member, thereby improving the feeding efficiency of the semi-dry pet food extruder.

[0015] Optionally, the extrusion tube has a vertical section and a material guiding section, the vertical section is located at the bottom of the raw material tank and is connected to the raw material tank, and the vertical section passes through the locking member.

[0016] By adopting the above technical solution, since the vertical section is located at the bottom of the raw material tank and passes through the locking piece, on the one hand, a rotational connection between the locking piece and the raw material tank is realized, and on the other hand, the extrusion tube and the workbench are avoided to ensure the movement of the raw material tank in the vertical direction.

[0017] Optionally, the extrusion tube further includes an extrusion section connected to the material guiding section, and the extrusion section is provided with a solenoid valve to control the opening and closing of the extrusion section.

[0018] By adopting the above technical solution, after the pressure plate squeezes the raw material in the raw material tank under the action of the driving member, the solenoid valve is started to open the extrusion section, and then the raw material is extruded and formed through the extrusion section, thereby avoiding the situation where the raw material is extruded in a loose state, so as to increase the molding effect of the raw material.

[0019] Optionally, at least two extrusion sections are provided, and each of the extrusion sections is provided with the solenoid valve.

[0020] By adopting the above technical solution, since at least two extrusion sections are provided, when the raw material is extruded, the raw material can be extruded through at least two extrusion sections to improve the extrusion efficiency of the raw material.

[0021] Optionally, a connecting ear is provided on the peripheral side of the raw material tank, and a guide column penetrating the connecting ear is provided on the top of the workbench.

[0022] By adopting the above technical solution, when the raw material tank moves in the vertical direction, the raw material tank drives the connecting ear to move, and the connecting ear and the guide column slide relative to each other, so that the relative sliding of the connecting ear and the guide column guides the movement direction of the raw material tank, so as to increase the stability of the raw material tank in the vertical direction. At the same time, it avoids the situation where the raw material tank may be misaligned with the pressure plate due to the movement of the raw material tank in the vertical direction, so as to ensure the production efficiency of the semi-dry pet food extruder.

[0023] Optionally, a support plate is provided on the top of the guide column, the driving member is provided on the top of the support plate, and the driving member has a driving end, and the driving end passes through the support plate and is connected to the pressure plate.

[0024] By adopting the above technical solution, since the support plate is arranged at the top of the guide column, the guide column can support the support plate, and the driving member is arranged on the support plate, the support plate supports the driving member, so as to increase the stability of the driving member, thereby ensuring the pressurizing effect of the pressure plate on the raw materials in the raw material tank.

[0025] Optionally, a plurality of connecting ears are arranged at intervals along the circumference of the raw material tank, and a plurality of guide pillars are arranged corresponding to the connecting ears.

[0026] By adopting the above technical solution, multiple connecting ears and guide columns are provided to increase the guiding points for the raw material tank, thereby further increasing the stability of the raw material tank when moving in the vertical direction, and at the same time ensuring that the raw material tank and the pressure plate are in an aligned state to ensure that the pressure plate can move into the raw material tank to pressurize the raw materials in the raw material tank.

[0027] Optionally, the pressure plate is provided with an annular groove along its circumference, and a sealing ring is provided in the annular groove.

[0028] By adopting the above technical solution, after the pressure plate moves into the raw material tank, the sealing ring is pressed against the inner wall of the raw material tank to increase the sealing between the pressure plate and the raw material tank, so as to avoid the raw materials in the raw material tank from overflowing through the gap between the pressure plate and the raw material tank when the pressure plate moves, so as to ensure the cleanliness of the pressure plate, thereby avoiding the need for staff to clean the pressure plate and reducing the workload of staff.

[0049] When using the semi-dry pet food extruder in the present application, first operate the locking member 4 to rotate the locking member 4 from the locking position to the avoidance position, and then make the locking member 4 and the center hole 111 form an avoidance, and the raw material tank 2 descends under the action of its own gravity, and then the feed port of the raw material tank 2 descends, and then the raw material is poured into the raw material tank 2, and then the raw material tank 2 is driven upward, so that the raw material tank 2 moves to the top of the workbench 1, and then the locking member 4 is reversed to make the locking member 4 cooperate with the top end surface stop of the workbench 1, so that the table surface of the workbench 1 supports the raw material tank 2, and then start the driving member 31, and the driving member 31 drives the pressure plate 32, so that the pressure plate 32 squeezes the raw material in the raw material tank 2, and the squeezed raw material is extruded through the extrusion tube 21 and formed into a desired shape.

[0051] Specifically, refer to Figure 1 and Figure 2 The workbench 1 includes a table top 11 and a plurality of supporting legs 12 arranged at the bottom of the table top 11. That is to say, the top end surface of the workbench 1 mentioned in the present application refers to the top end surface of the table top 11. The center hole 111 is arranged on the table top 11, and at the same time, a accommodating space is formed at the bottom of the table top 11.

[0052] The present application does not specifically limit the structure of the locking member 4, and it may adopt any one of the following embodiments:

[0053] Embodiment 1. In this embodiment, referring to Figures 1 to 5 The locking member 4 includes a turntable 41 rotatably connected to the raw material tank 2 and a locking block 42 arranged on the peripheral side of the turntable 41. The hole wall of the center hole 111 is provided with an avoidance groove 112 corresponding to the locking block 42. When the locking block 42 is in the avoidance position, the locking block 42 and the avoidance groove 112 are arranged opposite to each other in the vertical direction.

[0054] When the raw material is inverted into the raw material tank 2, the turntable 41 is first rotated to make the turntable 41 drive the locking block 42 to move, and then the locking block 42 moves to a position opposite to the avoidance groove 112, so that the raw material tank 2 and the turntable 41 slide downward through the center hole 111, so that the feed port of the raw material tank 2 is in a lower position; and after pushing the raw material tank 2 upward so that the raw material tank 2 is located above the workbench 1, the turntable 41 is rotated in the opposite direction, and then the locking block 42 is rotated to a position misaligned with the avoidance groove 112, and at the same time, the locking block 42 contacts the top end surface of the workbench 1, so that the locking block 42 and the turntable 41 support the raw material tank 2.

[0055] During the operation of the locking member 4, it is only necessary to rotate the turntable 41, thereby reducing the difficulty of operating the locking member 4, thereby further improving the efficiency of inverting the raw materials into the raw material tank 2, and further improving the production efficiency of pet food. In addition, the turntable 41 can also strengthen the bottom wall of the raw material tank 2 to increase the structural strength of the raw material tank 2, thereby increasing the service life of the raw material tank 2.

[0056] Better, refer to Figure 5 The locking block 42 and the rotating disk 41 are integrally formed to increase the connection strength between the two, thereby ensuring the stability of the support of the locking member 4 to the raw material tank 2.

[0057] In a preferred embodiment, referring to Figure 5 , a plurality of locking blocks 42 are arranged at intervals along the circumference of the turntable 41, and a plurality of avoidance grooves 112 are arranged corresponding to the locking blocks 42, thereby increasing the stopper matching points between the locking member 4 and the top end surface of the workbench 1, thereby increasing the support stability of the raw material tank 2, thereby ensuring the normal operation of the semi-dry pet food extruder. At the same time, the arrangement of multiple locking blocks 42 and multiple avoidance grooves 112 can reduce the required rotation angle of the locking member 4, so as to improve the feeding efficiency of the semi-dry pet food extruder.

[0058] In a preferred embodiment, referring to Figure 6 and Figure 7 The extrusion tube 21 has a vertical section 211 and a material guiding section 212. The vertical section 211 is located at the bottom of the raw material tank 2 and is connected to the raw material tank 2. The vertical section 211 is passed through the locking member 4. On the one hand, it realizes the rotational connection between the locking member 4 and the raw material tank 2. On the other hand, it realizes the avoidance of the extrusion tube 21 and the workbench 1 to ensure the movement of the raw material tank 2 in the vertical direction.

[0059] Further, see Figure 6 and Figure 7The extrusion tube 21 also includes an extrusion section 213 connected to the material guide section 212. The extrusion section 213 is provided with a solenoid valve 215 to control the opening and closing of the extrusion section 213. After the pressure plate 32 squeezes the raw material in the raw material tank 2 under the action of the driving member 31, the solenoid valve 215 is started so that the solenoid valve 215 opens the extrusion section 213, and then the raw material is extruded and formed through the extrusion section 213, thereby avoiding the situation where the raw material is extruded in a loose state, so as to increase the molding effect of the raw material.

[0060] It should be noted that the solenoid valve 215 mentioned above controls the opening and closing of the extrusion section 213, which means that the solenoid valve 215 can control the connection or disconnection between the extrusion section 213 and the outside world, so as to control the timing of extruding the raw materials.

[0061] Further, refer to Figure 6 and Figure 7 At least two extrusion sections 213 are provided, and each extrusion section 213 is provided with a solenoid valve 215.

[0063] Embodiment 2. In this embodiment, the locking member 4 is a locking rod slidably connected to the bottom of the raw material tank 2. The length direction of the locking rod is perpendicular to the central axis of the raw material tank 2, and when the locking rod is in the locking position, one end of the locking rod protrudes from the peripheral side of the raw material tank 2 so that the locking rod cooperates with the top table stop of the workbench 1; when the locking rod is in the avoidance position, the upward projection of the locking rod is located inside the raw material tank 2, so that the locking rod forms an avoidance with the center hole 111.

[0064] In a preferred embodiment, referring to Figure 1 , Figure 2 , Figure 3 and Figure 6, a connecting ear 22 is provided on the peripheral side of the raw material tank 2, and a guide column 113 is provided on the top of the workbench 1 and penetrates the connecting ear 22, so that when the raw material tank 2 moves in the vertical direction, the raw material tank 2 drives the connecting ear 22 to move, and the connecting ear 22 and the guide column 113 slide relative to each other, so that the relative sliding of the connecting ear 22 and the guide column 113 guides the movement direction of the raw material tank 2, so as to increase the stability of the raw material tank 2 in the vertical direction, and at the same time avoid the situation that the raw material tank 2 may be misaligned with the pressure plate 32 due to the movement of the raw material tank 2 in the vertical direction, so as to ensure the production efficiency of the semi-dry pet food extruder. In addition, the connecting ear 22 can also cooperate with the top end face stop of the workbench 1 to limit the extreme position where the raw material tank 2 can move downward, avoid the situation that the raw material tank 2 is separated from the workbench 1, and then increase the connection stability between the raw material tank 2 and the workbench 1.

[0065] In a preferred embodiment, referring to Figure 1 and Figure 2 A support plate 114 is disposed on the top of the guide column 113 , and a driving member 31 is disposed on the top of the support plate 114 . The driving member 31 has a driving end, which passes through the support plate 114 and is connected to the pressure plate 32 .

[0066] Since the support plate 114 is arranged on the top of the guide column 113, the guide column 113 can support the support plate 114, and the driving member 31 is arranged on the support plate 114, so that the support plate 114 supports the driving member 31 to increase the stability of the driving member 31, thereby ensuring the pressurizing effect of the pressure plate 32 on the raw materials in the raw material tank 2.

[0067] Better, refer to Figure 1 , Figure 2 and Figure 5 A plurality of connecting ears 22 are arranged at circumferential intervals along the raw material tank 2, and a plurality of guide columns 113 are arranged corresponding to the connecting ears 22 to increase the guiding points of the raw material tank 2, thereby further increasing the stability of the raw material tank 2 when moving in the vertical direction, and at the same time ensuring that the raw material tank 2 and the pressure plate 32 are in an aligned state to ensure that the pressure plate 32 can move into the raw material tank 2 to pressurize the raw materials in the raw material tank 2.

[0069] In a preferred embodiment, referring to Figure 1 and Figure 2The pressure plate 32 is provided with an annular groove along its circumference, and a sealing ring 321 is provided in the annular groove, so that after the pressure plate 32 moves into the raw material tank 2 under the action of the driving member 31, the sealing ring 321 presses against the inner wall of the raw material tank 2 to increase the sealing between the pressure plate 32 and the raw material tank 2, so as to avoid the raw materials in the raw material tank 2 from overflowing through the gap between the pressure plate 32 and the raw material tank 2 when the pressure plate 32 moves, so as to ensure the cleanliness of the pressure plate 32, thereby avoiding the need for the staff to clean the pressure plate 32, so as to reduce the workload of the staff. At the same time, the setting of the sealing ring 321 allows a certain gap between the circumference of the pressure plate 32 and the inner wall of the raw material tank 2, so as to avoid the circumference of the pressure plate 32 and the inner wall of the raw material tank 2 to generate noise, so as to ensure the comfort of the working environment of the staff.
