Description

Technical Field

[0001] This utility model relates to the field of feed processing technology, specifically to a twin-shaft mixer for feed pelleting. Background Technology

[0002] The twin-shaft mixer is a widely used material mixing equipment in industries such as feed, chemicals, and coatings. Its core function is to achieve efficient mixing of powders, dry powders, and other materials through a twin-shaft design. The twin-shaft mixer plays a crucial role in feed processing production lines, offering a short mixing cycle, typically achieving the required mixing uniformity within 40-60 seconds. Developed and manufactured by several high-tech enterprises, this equipment features a short mixing cycle (generally 40-60 seconds to achieve the required mixing uniformity), small footprint, and ease of operation. In feed processing, dry powder mortar preparation, and solid waste resource treatment, the twin-shaft mixer ensures material quality by optimizing the feeding sequence and controlling mixing time, and is equipped with an after-sales service guarantee system.

[0003] The biaxial mixer disclosed in the publication (publication number: 202420767855.6) includes a cylindrical body; a first stirring shaft; a second stirring shaft; a first stirring blade; and a second stirring blade. The first stirring blade and the second stirring blade are alternately staggered, and the distance between the first stirring shaft and the second stirring shaft is less than the sum of the stirring radii of the first stirring blade and the stirring radii of the second stirring blade. The cylindrical body includes an opening that connects the first cavity and the second cavity, and discharge ports respectively located at the bottom of the first cavity and the bottom of the second cavity. The discharge mechanism includes a discharge gate hinged to the cylindrical body, a linkage component for driving the discharge gate to close or open, and a drive component for driving the linkage component.

[0004] The aforementioned twin-shaft mixer uses the cooperation of components such as a cylinder, stirring shaft, stirring blades, unloading mechanism, and linkage assembly to mix materials. However, the stirring diameter of its stirring blades cannot be fully adapted to the internal space of the cylinder, resulting in low mixing efficiency and the inability to crush materials while mixing. Therefore, there is an urgent need for a twin-shaft mixer for feed pelleting to solve the above problems. Utility Model Content

[0005] To overcome the above-mentioned defects, the present invention provides a twin-shaft mixer for feed pelleting, which solves the technical problems in the prior art where the mixing diameter of the mixing blades cannot be fully adapted to the internal space of the cylinder, and where the material cannot be crushed at the same time as mixing.

[0006] According to one aspect, at least one embodiment of the present invention provides a bi-shaft mixer for feed pelleting, comprising: a mixing chamber, a base fixedly connected to the bottom of the mixing chamber, a feeding port opened at the top of the mixing chamber, a drive motor unit fixedly connected to the right side of the mixing chamber, a rotating shaft fixedly connected to the output shaft of the drive motor unit, a telescopic stirring device provided on the circumferential surface of the rotating shaft, the telescopic stirring device including a first telescopic rod, the first telescopic rod fixedly connected to the circumferential surface of the rotating shaft, a spring fixedly connected to one end of the inner wall of the first telescopic rod, a second telescopic rod fixedly connected to the other end of the spring, a blade fixedly connected to the other end of the second telescopic rod, a triangular plate fixedly connected to one end of the blade, a toothed blade fixedly connected to the front side of the triangular plate, and a long toothed blade fixedly connected to the inner wall of the mixing chamber.

[0007] For example, in at least one embodiment of the present invention, a twin-shaft mixer for feed pelleting is provided, which further includes: the drive motor unit includes a support plate, the support plate is fixedly connected to the right side of the mixing chamber, the top of the support plate is fixedly connected to the motor unit, and the top of the motor unit is fixedly connected to an external motor. This design can enable the two rotating shafts to rotate in opposite directions so as to mix the materials more thoroughly.

[0008] For example, in at least one embodiment of the present invention, a bi-shaft mixer for feed pelleting is provided, which further includes: the number of the telescopic stirring devices is set to several groups and arranged linearly on the circumferential surface of the rotating shaft. This design ensures the high efficiency of the equipment's stirring.

[0009] For example, in at least one embodiment of the present invention, a twin-shaft mixer for feed pelleting is provided, which further includes a horizontal W-shaped mixing chamber, such a design that ensures that there are no dead corners in the mixing process.

[0010] For example, in a bi-shaft mixer for feed pelleting provided in at least one embodiment of the present invention, the number of the toothed blades is set to several and arranged linearly on the front side of the triangular plate, and the number of the long toothed blades is set to several and arranged linearly on the inner wall of the mixing chamber. This design enables the material to achieve the effect of crushing during the mixing and stirring process.

[0011] According to another aspect, at least one embodiment of the present invention also provides a twin-shaft mixer for feed pelleting, comprising: a filtering and crushing device provided at the bottom of the feeding port, the filtering and crushing device including a support block, the support block being fixedly connected to the bottom of the discharge port, a filter plate being fixedly connected to the bottom of the support block, filter holes being provided on the front and side surfaces of the filter plate, a motor being fixedly connected to the right side of the support block, a pressure roller being fixedly connected to the output shaft of the motor, and a gear sleeve being fixedly connected to the circumferential surface of the pressure roller. This design allows the material to be filtered before mixing and stirring, which can crush larger lumps and make the mixing and stirring process more efficient and smooth.

[0012] For example, in at least one embodiment of the present invention, a biaxial mixer for feed pelleting is provided, which further includes: the number of filter holes is set to several and arranged in a linear array on the front side of the filter plate, such a design ensures the stability of filtration.

[0013] For example, in at least one embodiment of the present invention, a twin-shaft mixer for feed pelleting is provided, which further includes: the second rotating shaft is fixedly inserted inside the pressure roller. This design allows the pressure roller to rotate smoothly so as to crush the material.

[0014] For example, in a bi-shaft mixer for feed pelleting provided in at least one embodiment of the present invention, the number of the pressure rollers is set to two and they are symmetrical about the vertical central axis of the support block, and the number of the gear sleeves is set to two and they are symmetrical about the vertical central axis of the support block. This design ensures the stability of the rolling process.

[0015] For example, in at least one embodiment of this utility model, a bishaft mixer for feed pelleting further includes: two gear sleeves symmetrically positioned along the vertical central axis of the support block, with the two gear sleeves meshing with each other. This design ensures the stability of the compaction process.

[0016] The beneficial effects of this utility model are as follows: In this invention, by setting up a telescopic stirring device, when the device is mixing and stirring, the rotating shaft rotates and drives the first telescopic rod to rotate, the first telescopic rod drives the second telescopic rod to rotate, thereby driving the blade to rotate. Due to the elasticity of the spring, when the blade touches the inner wall of the mixing chamber, the telescopic rod will shorten back, thereby adapting to the space inside the mixing chamber, and achieving the effect of the stirring diameter of the stirring blade adapting to the internal space of the cylinder.

[0017] In this invention, through the setting of the filtering and crushing device and the design of the toothed blades, when the material enters the mixing chamber through the feeding port, the motor starts and drives the pressure roller to rotate. Through the meshing gear sleeve, the second pressure roller is driven to rotate, crushing the larger lumps of material in the first step. The crushed material enters the mixing chamber through the filter holes on the filter plate for mixing and stirring. Through the toothed blades set on the triangular plate and the long toothed blades on the inner wall of the mixing chamber, when the blades rotate and collide with each other or when the blades touch the inner wall of the mixing chamber, the toothed blades can further crush the material, achieving the effect of crushing the material while stirring.

[0026] like Figures 1-5As shown, a bi-shaft mixer for feed pelleting is illustrated in one embodiment of the present invention. It includes a mixing chamber 1, a base 2 fixedly connected to the bottom of the mixing chamber 1, a feeding port 3 at the top of the mixing chamber 1, a drive motor 4 fixedly connected to the right side of the mixing chamber 1, a rotating shaft 5 fixedly connected to the output shaft of the drive motor 4, and a telescopic stirring device 6 provided on the circumferential surface of the rotating shaft 5. The telescopic stirring device 6 includes a first telescopic rod 61, which is fixedly connected to the circumferential surface of the rotating shaft 5. A spring 62 is fixedly connected to one end of the inner wall of the first telescopic rod 61, and a second telescopic rod 63 is fixedly connected to the other end of the spring 62. A blade 64 is fixedly connected to the other end of the second telescopic rod 63, and a triangular plate 65 is fixedly connected to one end of the blade 64. A toothed blade 66 is fixedly connected to the front side of the triangular plate 65, and a long toothed blade 67 is fixedly connected to the inner wall of the mixing chamber 1.

[0027] For example, in at least one embodiment of the present invention, a twin-shaft mixer for feed pelleting is provided, which further includes: a drive motor unit 4 including a support plate 41, the support plate 41 being fixedly connected to the right side of the mixing chamber 1, a motor unit 42 being fixedly connected to the top of the support plate 41, and an external motor 43 being fixedly connected to the top of the motor unit 42. This design can enable the two rotating shafts 5 to rotate in opposite directions so as to mix the materials more thoroughly.

[0028] For example, in a bi-shaft mixer for feed pelleting provided in at least one embodiment of the present invention, the number of telescopic stirring devices 6 is set to several groups and arranged in a linear array on the circumferential surface of the rotating shaft 5. This design ensures the high efficiency of the equipment's stirring.

[0029] For example, in at least one embodiment of the present invention, a twin-shaft mixer for feed pelleting is provided, which further includes a mixing chamber 1 in the shape of a horizontal W, such a design ensures that there are no dead corners in the mixing and stirring process of the material.

[0030] For example, in at least one embodiment of the present invention, a bi-shaft mixer for feed pelleting is provided, which further includes: a number of toothed blades 66 arranged in a linear array on the front side of a triangular plate 65, and a number of long toothed blades 67 arranged in a linear array on the inner wall of the mixing chamber 1. This design enables the material to achieve a crushing effect during the mixing and stirring process.

[0031] This embodiment provides a twin-shaft mixer for feed pelleting. With the telescopic stirring device 6, when the device is mixing, the rotating shaft 5 rotates, driving the first telescopic rod 61 to rotate. The first telescopic rod 61 drives the second telescopic rod 63 to rotate, thereby driving the blade 64 to rotate. Due to the elasticity of the spring 62, when the blade 64 touches the inner wall of the mixing chamber 1, the telescopic rod will shorten back, thereby adapting to the space inside the mixing chamber 1, achieving the effect of the stirring diameter of the stirring blade adapting to the internal space of the cylinder.

[0032] In some examples, to achieve the effect of adapting the stirring diameter of the stirring blade to the internal space of the cylinder, a telescopic stirring device 6 is set up. When the device is mixing, the drive motor 4 is started. The motor 42 has two meshing gears inside, which are fixedly connected to two rotating shafts 5 respectively. At the same time, the output shaft of the external motor 43 is connected to a gear through a bevel gear set. When the external motor 43 is started, it drives one gear to rotate through the bevel gear set. This gear drives the other gear to rotate, and the two gears rotate in opposite directions. The two gears drive the two rotating shafts 5 to rotate in both directions. The rotation of the rotating shafts 5 drives the first telescopic rod 61 to rotate, and the first telescopic rod 61 drives the second telescopic rod 63 to rotate, thereby driving the blade 64 to rotate. Due to the elasticity of the spring 62, when the blade 64 touches the inner wall of the mixing chamber 1, the telescopic rod will retract, thereby adapting to the internal space of the mixing chamber 1 and achieving the effect of adapting the stirring diameter of the stirring blade to the internal space of the cylinder.

This design allows the material to be filtered before mixing and stirring, which can crush larger lumps and make the mixing and stirring process more efficient and smooth.

[0034] For example, in a biaxial mixer for feed pelleting provided in at least one embodiment of the present invention, the number of filter holes 73 is set to several and arranged in a linear array on the front side of the filter plate 72. This design ensures the stability of filtration.

[0035] For example, in at least one embodiment of the present invention, a twin-shaft mixer for feed pelleting is provided, which further includes: a second rotating shaft 75 fixedly passing through the inside of a pressure roller 76. This design allows the pressure roller 76 to rotate smoothly so as to crush the material.

[0036] For example, in a bi-shaft mixer for feed pelleting provided in at least one embodiment of the present invention, the following are also included: the number of pressure rollers 76 is set to two and they are symmetrical about the vertical central axis of the support block 71; the number of gear sleeves 77 is set to two and they are symmetrical about the vertical central axis of the support block 71. This design ensures the stability of the rolling process.

[0037] For example, in a bi-shaft mixer for feed pelleting provided in at least one embodiment of the present invention, the number of gear sleeves 77 is set to two, and they are symmetrical along the vertical central axis of the support block 71, and the two gear sleeves 77 mesh with each other.

[0038] In this embodiment, through the setting of the filter and crushing device 7 and the design of the toothed blade 66, when the material enters the mixing chamber 1 through the feed port 3, the motor 74 starts and drives the pressure roller 76 to rotate. Through the meshing gear sleeve 77, the second pressure roller 76 is driven to rotate, and the larger lumps of material are crushed in the first step. The crushed material enters the mixing chamber 1 through the filter holes 73 on the filter plate 72 for mixing and stirring. Through the toothed blade 66 set on the triangular plate 65 and the long toothed blade 67 on the inner wall of the mixing chamber 1, when the blades 64 rotate and collide with each other and when the blades 64 touch the inner wall of the mixing chamber 1, the toothed blade 66 can further crush the material, realizing the effect of crushing the material while stirring.

[0039] In this embodiment, in order to achieve the effect of crushing materials while stirring, the filter and crushing device 7 and the toothed blade 66 are designed so that when the material enters the mixing chamber 1 through the feed port 3, the motor 74 starts and drives the pressure roller 76 to rotate. The gear sleeve 77 drives the second pressure roller 76 to rotate, crushing the larger lumps of material in the first step. The crushed material enters the mixing chamber 1 through the filter holes 73 on the filter plate 72 for mixing. The toothed blade 66 on the triangular plate 65 and the long toothed blade 67 on the inner wall of the mixing chamber 1 further crush the material when the blades 64 rotate and collide with each other or when the blades 64 touch the inner wall of the mixing chamber 1, thus achieving the effect of crushing materials while stirring.
