Description

Technical Field

[0001] The present invention relates to the technical field of pet food processing equipment, and particularly relates to a bone mud mill for pet food processing with adjustable gap. Background Art

[0002] The bone mud mill for pet food processing, also known as a bone crusher or colloid mill, is a device specifically used to grind animal bones (such as chicken bones, fish bones, pig bones, etc.) into a mud-like state. Through the relative movement of the stator and rotor with different geometric shapes under high-speed rotation, the bone is subjected to composite forces such as shear force and friction force, and is broken, dispersed, emulsified and mixed to form delicate bone mud.

[0003] An improved bone mud mill with the publication number of CN202070388U is disclosed. Specifically, it includes a machine base, a motor is provided at the upper end of the machine base, the motor is connected to a main shaft, the main shaft is connected to a stator, the stator is connected to a rotor, a fixing ring is provided at the upper end of the rotor, a hopper is provided on the fixing ring, a discharge port is provided on one side where the stator and the rotor are cooperatively connected, an adjusting ring is provided on one side of the stator, a fixing rod is provided on one side of the adjusting ring, a centrifugal disc is provided at the lower end of the rotor, and an overflow hole is provided on the other side where the stator and the rotor are cooperatively connected.

[0004] The gap between the two grinding rollers of the existing bone mud mill for pet food processing is fixed, resulting in uneven bone mud particle size. If the gap is too large, the bone mud particle size is relatively coarse, which does not meet the fineness requirements of pet food; if the gap is too small, although the bone mud particle size is fine, it will increase the equipment load and may cause excessive wear of the grinding rollers, thus affecting the bone mud particle size. Therefore, we propose a bone mud mill for pet food processing with adjustable gap. Summary of the Invention

[0017] The beneficial effects of the gap-adjustable bone mud grinder for pet food processing proposed by the present invention are as follows:

[0018] For the gap-adjustable bone mud grinder for pet food processing in this application, according to the size of animal bones or the required size of bone mud particle size, the distance between the two grinding rollers can be flexibly adjusted. By rotating the turntable to drive the bidirectional lead screw to rotate, the two grinding rollers can be driven to move closer to or away from each other, thereby adjusting the distance between the two grinding rollers. The adjustable distance between the grinding rollers enables the bone mud grinder to process bone raw materials of different sizes and hardnesses, and at the same time, bone mud products of different particle sizes and textures can be obtained, improving the versatility and flexibility of the equipment.

[0019] For the gap-adjustable bone mud grinder for pet food processing in this application, the heat generated during the grinding process can be absorbed by the grinding rollers, and the low-temperature air from the outside enters the cavity through the air duct, so that the low-temperature air exchanges heat with the grinding rollers, which can accelerate the heat dissipation efficiency of the grinding rollers, prevent the equipment from overheating and extend the service life of the grinding rollers.

[0020] The animal bones are guided by the two flow guiding plates. When the distance between the two flow guiding plates is in the minimum state, the flow rate of the animal bones between the two flow guiding plates is small, and the processing capacity of the device is in a low-load state. In the low-load state, the processing capacity of the device is relatively low, which helps to achieve a finer grinding effect. At the same time, combined with the slower rotation speed of the grinding rollers, the grinding rollers can contact the raw materials more fully, so as to grind them into finer and more uniform bone mud.

[0021] When the electromagnet is energized and adsorbs the magnetic sheet, the two flow guiding plates can be separated from each other. The limiting block fits on the buffer pad on the same side as it. The gap between the two flow guiding plates increases, and the flow rate of animal bones relatively increases, which can meet the high - efficiency production requirements, thus meeting the production requirements in different scenarios. By intermittently energizing the electromagnet through an external controller, the limiting block can intermittently impact on the limiting block. The buffer pad can buffer the impact between the two. Through the impact, the flow guiding plate generates vibration, which can make the animal bones attached to the flow guiding plate separate from the flow guiding plate, making the animal bones between the two flow guiding plates pass more smoothly.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0032] Embodiment 1

[0033] Referring to Figure 1-8 As shown, a bone mud grinder for pet food processing with adjustable gap includes a housing 1. Support feet 2 are fixedly installed on both sides of the housing 1. Channels 3 are provided on both sides of the housing 1. Two spaced supports 4 are slidably arranged in the channels 3. Two spaced guide rods 5 are arranged in the channels 3. The ends of the guide rods 5 are fixedly connected to the housing 1, and the guide rods 5 all penetrate through the supports 4. The upper end of the housing 1 is open. Two spaced grinding rollers 6 are provided in the inner cavity of the housing 1. Grinding teeth 28 are provided on the surface of the grinding rollers 6. Connecting shafts 7 are fixedly installed at both ends of the grinding rollers 6. The end parts of the connecting shafts 7 are rotatably installed on the supports 4 respectively. A bidirectional lead screw 8 is arranged in the channel 3 on one side. The bidirectional lead screw 8 penetrates through the two supports 4 and is threadedly connected to the supports 4. The end of the bidirectional lead screw 8 is rotatably installed on the housing 1. A turntable 9 is rotatably installed outside the housing 1. The rotating shaft of the turntable 9 is fixedly connected to the bidirectional lead screw 8. A driving mechanism is installed outside the housing 1. The driving mechanism is connected to the two connecting shafts 7 on the same side. The driving mechanism is used to drive the two grinding rollers 6 to rotate.

[0034] Among them, shock pads 27 are provided at the bottoms of the support feet 2. A discharge channel 10 is fixedly installed at the bottom of the housing 1. The discharge channel 10 penetrates into the housing 1. The upper port of the discharge channel 10 is located between the two grinding rollers 6. The bone mud ground by the two grinding rollers 6 falls between the two grinding rollers 6. The material then falls into the discharge channel 10 and is diverted to the outside of the housing 1 through the discharge channel 10.

[0035] Among them, diversion inclined surfaces 19 are provided at both ends of the grinding rollers 6. The diversion inclined surfaces 19 are distributed along the end parts of the grinding rollers 6. By providing the diversion inclined surfaces 19, the animal bones overflowing on the grinding rollers 6 are guided and limited to prevent the animal bones from overflowing from both ends of the grinding rollers 6.

[0036] Among them, the driving mechanism includes two first bevel gears 11. The two first bevel gears 11 are respectively rotatably installed on two connecting shafts 7 on the same side. A spline sleeve 12 is rotatably installed outside the housing 1. A spline groove is provided inside the spline sleeve 12. A linkage shaft 13 is rotatably installed on each of the two supports 4 on one side. An external spline is provided at one end of each linkage shaft 13. The linkage shafts 13 are inserted into the spline sleeve 12 and are in spline fit with the spline sleeve 12. A second bevel gear 14 is fixedly installed at the other end of each linkage shaft 13. The second bevel gears 14 on the same side are meshed with the first bevel gears 11. The driving mechanism further includes a driven wheel 15. The driven wheel 15 is fixedly installed on the spline sleeve 12. A protective cover 16 is fixedly installed on the housing 1. A motor 17 is fixedly installed inside the protective cover 16. A driving wheel 18 is fixedly installed at the output shaft end of the motor 17. The driving wheel 18 is meshed with the driven wheel 15.

[0037] By putting animal bones into the housing 1 and then letting them fall between the two grinding rollers 6, the motor 17 drives the driving wheel 18 to rotate. The driving wheel 18 drives the driven wheel 15 to rotate. The spline sleeve 12 rotates synchronously. The second bevel gears 14 at both ends rotate and drive the first bevel gears 11 to rotate. The first bevel gears 11, the connecting shafts 7 and the grinding rollers 6 rotate synchronously, so as to drive the two grinding rollers 6 to rotate synchronously and in opposite directions, and the animal bones between them can be crushed and ground to be processed into a mud shape. The bone mud mill of the present application has the characteristics of reasonable structure, simple operation and wide applicability, and is an important equipment for producing pet food (such as cat food, dog food).

[0038] During the production process, according to the size of animal bones or the required size of bone mud particle size, the distance between the two grinding rollers 6 can be flexibly adjusted. Specifically, by rotating the turntable 9 to drive the bidirectional lead screw 8 to rotate, the bidirectional lead screw 8 rotates and drives the two supports 4 to move along the direction of the guide rod 5, and the moving directions of the two supports 4 are opposite. The two supports 4 move closer to or away from each other, so that the supports 4, the connecting shafts 7 and the grinding rollers 6 move synchronously, and the two grinding rollers 6 can be driven to move closer to or away from each other, thereby adjusting the distance between the two grinding rollers 6.

[0039] The adjustable distance between the grinding rollers 6 enables the bone mud mill to process bone raw materials of different sizes and hardnesses. Whether it is the bones of large animals or small animals, or even the bones of different parts, they can all be adapted by adjusting the distance, thereby improving the versatility and flexibility of the equipment. At the same time, bone mud products with different particle sizes and textures can be obtained. This meets the needs of the pet food market for diversified products, such as bone mud pet food with different tastes and different nutritional components.

[0040] The bone mud ground by the two grinding rollers 6 falls between the two grinding rollers 6, and the material then falls into the discharge channel 10 and is diverted to the outside of the housing 1 through the discharge channel 10.

[0041] Embodiment 2

[0042] Referring to Figure 5-8 As shown, as another preferred embodiment of the present invention, the difference from Embodiment 1 is that a cavity 30 is provided inside the grinding roller 6. The grinding roller 6 is made of heat-conducting metal. The grinding roller 6 is made of iron. Air channels 29 are provided inside both connecting shafts 7 on the other side. The air channels 29 of the connecting shafts 7 are respectively communicated with the cavity 30 of the grinding roller 6, and the air channels 29 of the connecting shafts 7 are communicated with the outside.

[0043] The heat generated during the grinding process can be absorbed by the grinding roller 6. The low-temperature air from the outside enters the cavity 30 through the air channel 29. Thus, the low-temperature air exchanges heat with the grinding roller 6, which can accelerate the heat dissipation efficiency of the grinding roller 6 and prevent the equipment from overheating. Continuous high temperature will accelerate the wear and aging of the grinding roller 6 and shorten its service life. By accelerating heat dissipation, the roller temperature can be reduced, thereby prolonging the service life of the grinding roller 6 and reducing the replacement frequency and cost.

[0044] Among them, a feeding mechanism is provided at the upper port of the housing 1. The feeding mechanism is used to introduce the material between the two grinding rollers 6. The feeding mechanism includes a hopper 20. The hopper 20 is arranged at the upper port of the housing 1 and fixedly installed on the housing 1. The lower port of the hopper 20 is arranged between the two grinding rollers 6. The feeding mechanism further includes two symmetrically distributed guide plates 21. The guide plates 21 are both arranged inside the hopper 20. The guide plates 21 are arranged in a bent shape. One end of the guide plate 21 penetrates through the hopper 20, and limit blocks 22 are fixedly installed at the ends of the guide plates 21 extending outside the hopper 20. Adjusting mechanisms are provided on both sides inside the hopper 20. The adjusting mechanisms are installed on the guide plates 21, and the adjusting mechanisms on both sides are used to adjust the distance between the two guide plates 21. The adjusting mechanism includes magnetic chips 23. The magnetic chips 23 are arranged inside the hopper 20. The magnetic chips 23 are fixedly installed at the lower ends of the guide plates 21. Electromagnets 24 are fixedly installed inside the hopper 20. The electromagnets 24 face the magnetic chips 23. The electromagnets 24 are electrically connected to an external controller, and the electromagnets 24 can apply an adsorption force to the magnetic chips 23 when energized. Baffles 25 are provided on both sides of the hopper 20. The baffles 25 are located inside the housing 1 and the ends are fixedly installed on the housing 1. A buffer pad 26 is fixedly connected to the side of the baffle 25 facing the limit block 22.

[0045] The animal bones are added through the hopper 20, and the animal bones are guided by the two guide plates 21. Under normal conditions, the limit blocks 22 are attached to the outer wall of the hopper 20, and the distance between the two guide plates 21 is in the minimum state. The flow rate of the animal bones between the two guide plates 21 is relatively small, and the processing capacity of the device is in a low-load state. In the low-load state, the processing capacity of the device is relatively low, which helps to achieve a finer grinding effect. At the same time, in cooperation with the slower rotation speed of the grinding roller 6, the grinding roller 6 can contact the raw material more fully, so as to grind it into finer and more uniform bone paste.

[0046] When it is necessary to increase production efficiency, the electromagnet 24 is energized to attract the magnetic sheet 23, which can make the two flow guiding plates 21 move away from each other. The limiting block 22 fits on the buffer pad 26 on the same side as it, and the gap between the two flow guiding plates 21 increases, and the flow rate of animal bones relatively increases, so as to meet the production requirements under different scenarios. By intermittently energizing the electromagnet 24 through an external controller, the limiting block 22 can intermittently impact on the limiting block 22. The impact between the two can be buffered through the buffer pad 26. By the impact, the flow guiding plate 21 generates oscillation, which can make the animal bones attached to the flow guiding plate 21 separate from the flow guiding plate 21, and make the animal bones between the two flow guiding plates 21 pass more smoothly.

[0047] Working principle:

[0048] Put the animal bones into the housing 1 and then let them fall between the two grinding rollers 6. The motor 17 drives the driving wheel 18 to rotate, the driving wheel 18 drives the driven wheel 15 to rotate, and the spline sleeve 12 rotates synchronously. The second bevel gears 14 at both ends rotate and drive the first bevel gear 11 to rotate. The first bevel gear 11, the connecting shaft 7 and the grinding roller 6 rotate synchronously, so as to drive the two grinding rollers 6 to rotate synchronously and in opposite directions, and the animal bones between them can be crushed and ground into a mud state. During the production process, according to the size of the animal bones or the required particle size of the bone mud, the distance between the two grinding rollers 6 can be flexibly adjusted. Specifically, rotate the turntable 9 to drive the bidirectional lead screw 8 to rotate. The bidirectional lead screw 8 rotates and drives the two supports 4 to move along the direction of the guide rod 5, and the moving directions of the two supports 4 are opposite. The two supports 4 move closer to or away from each other, so that the supports 4, the connecting shaft 7 and the grinding roller 6 move synchronously, and the two grinding rollers 6 can be driven to move closer to or away from each other, thereby adjusting the distance between the two grinding rollers 6.

[0049] The animal bones are added from the hopper 20, and the two flow guiding plates 21 are used to guide the animal bones. Under normal conditions, the limiting block 22 fits on the outer wall of the hopper 20, the distance between the two flow guiding plates 21 is in the minimum state, the flow rate of the animal bones between the two flow guiding plates 21 is small, and the processing capacity of the device is in a low-load state. In the low-load state, the processing capacity of the device is relatively low, which helps to achieve a finer grinding effect. At the same time, the slower rotation speed of the grinding roller 6 is coordinated to enable the grinding roller 6 to contact the raw materials more fully, so as to grind them into a finer and more uniform bone mud.

[0050] When it is necessary to improve production efficiency, the electromagnet 24 is energized to adsorb the magnetic sheet 23, which can make the two flow guide plates 21 move away from each other. The limit block 22 fits on the buffer pad 26 on the same side as it, and the gap between the two flow guide plates 21 increases, and the flow rate of animal bones relatively increases, so as to meet the production requirements under different scenarios. By intermittently energizing the electromagnet 24 through an external controller, the limit block 22 can intermittently impact on the limit block 22, and the impact between the two can be buffered through the buffer pad 26. By the impact, the flow guide plate 21 generates oscillations, which can make the animal bones attached to the flow guide plate 21 separate from the flow guide plate 21.

[0051] The bone paste ground by the two grinding rollers 6 falls between the two grinding rollers 6, and the material then falls into the discharge channel 10 and is guided to the outside of the housing 1 through the discharge channel 10.

[0052] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
