Description

Technical Field

[0001] This utility model relates to the field of gyratory pellet mill technology, specifically to a gyratory pellet mill with automatic feeding function. Background Technology

[0002] The oscillating pellet mill is a high-efficiency, multi-functional pelletizing equipment. It uses an electric motor to drive a rotating drum to oscillate, and in conjunction with a screen and possible spray device, it can uniformly mix powder or small lumps of materials and shape them into pellets of the required size. It is widely used in the pharmaceutical, chemical, and food industries, and has the advantages of high production efficiency, simple operation, strong adaptability, and compliance with GMP requirements. It is an ideal choice for material pelletizing.

[0003] In existing technology, the operation of a gyratory pellet mill requires the raw material to be placed at its inlet and crushed by the force of the rotating drum. However, when the raw material contains large lumps, these large pieces may get stuck at the inlet or in the gap between the rotating drum and the screen, causing blockage. This blockage not only affects the continuous production capacity of the equipment but may also damage it, such as abrading the drum surface and tearing the screen. Furthermore, when large pieces of raw material enter, the drum may not be able to effectively crush them into the required small particles, resulting in poor crushing effect and low operating efficiency of the gyratory pellet mill. Utility Model Content

[0004] The purpose of this invention is to provide a gyratory pellet mill with automatic feeding function to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A vibrating pellet mill with automatic feeding function includes:

[0007] The base has a gyratory pellet mill body fixedly connected to the top of it. A collection box is set below the gyratory pellet mill body and fixedly connected to the base. A controller is fixedly connected to one side of the gyratory pellet mill body. A bracket is fixedly connected to the base. A crushing box is fixedly connected to the top of the base. A crushing motor is fixedly connected to one side of the crushing box. A processing box is fixedly connected to the top of the base.

[0008] The crushing component is located above the base and is used to crush the raw materials.

[0009] The processing unit, located above the base, is used to process the dust generated during the crushing of raw materials.

[0010] The feeding component is located on one side of the crushing component and is used to transport the raw materials to the inlet of the gyratory pellet mill body.

[0011] When feeding is required, the controller operates the crushing, processing, and feeding components in conjunction to feed raw materials into the inlet at the top of the crushing chamber. The raw materials are then processed by the crushing components and fall into the outlet of the collection box, from where they enter the feeding component. The feeding component then transports the raw materials into the main body of the gyratory pellet mill for further processing. Simultaneously, the processing component collects the dust generated during crushing, preventing dust leakage and resource waste. The operation of the crushing, processing, and feeding components prevents large raw materials from entering the gyratory pellet mill and affecting its operation, thus improving its efficiency. The working principle of the gyratory pellet mill is based on gyratory motion and particle adhesion. An electric motor drives a rotating drum, which, in conjunction with a spraying device, evenly sprays liquid or impregnation solution onto the material surface. Simultaneously, the screen vibrates up and down, causing the material to continuously roll and tumble on the screen, achieving uniform coating and drying of the particles. The gyratory pellet mill is a mature technology for pelletizing and will not be elaborated upon further in this article.

[0012] A further improvement of the present invention is that the crushing component includes a crushing roller, which is symmetrically arranged and rotatably connected to the crushing box. One end of the crushing roller is fixedly connected to the output end of the crushing motor, and the other end of the crushing roller is fixedly connected to a gear. The symmetrically arranged gears mesh with each other.

[0013] In the above technical solution, when the raw material needs to be crushed, the crushing motor is controlled by the controller to work. The crushing motor drives the crushing roller fixedly connected to its output end to rotate. The rotation of the crushing roller transmits power to the other crushing roller through the meshing gears at one end, so that the symmetrically arranged crushing rollers rotate in opposite directions, thereby crushing the raw material. When the raw material enters from the top of the crushing box, the larger raw materials will be crushed by the symmetrically arranged crushing rollers and then fall to the bottom of the crushing box and fall into the feeding component through the discharge port. The operation of the symmetrically arranged crushing rollers can crush the raw material, thereby improving the working efficiency of the oscillating pellet mill.

[0014] A further improvement of the present invention is that the processing component includes a cam and a piston cylinder. The piston cylinder is located on one side of the crushing box and is fixedly connected to the crushing box. A piston plate is slidably connected inside the piston cylinder. A piston rod is fixedly connected to one end of the piston plate. A pressure plate is fixedly connected to the end of the piston rod away from the piston plate. A spring is fixedly connected to the side of the piston plate near the piston rod. The other end of the spring is fixedly connected to the piston cylinder. The cam is fixedly connected to the end of the crushing roller near the gear. The cam and the pressure plate work together. A collection box is slidably connected inside the processing box. A first filter screen is provided above the collection box and is fixedly connected to the collection box.

[0015] In the above technical solution, when the crushing motor drives the crushing roller to rotate, it drives the cam fixedly connected to it to rotate. The rotation of the cam squeezes the pressure plate. At this time, the spring is in a stretched state, and the gas in the piston cylinder is transported from the outlet pipe to the collection box through the one-way valve in the outlet pipe. Then, the gas passes through the first filter screen, and the dust it carries is intercepted by the first filter screen and falls into the collection box. The air enters the crushing chamber through the pipe. When the cam disengages from the pressure plate, the pressure plate is reset under the action of the spring. The gas containing dust in the crushing chamber enters the piston cylinder through the feed pipe and the one-way valve. When large raw materials are crushed, dust is also generated along with them. This dust will be emitted from the crushing chamber, disturbing the workers, wasting raw materials, and reducing the working efficiency of the gyratory pellet mill. By setting up a processing component, the dust can be collected, thereby avoiding resource waste and improving the working efficiency of the gyratory pellet mill.

[0016] A further improvement of the present invention is that the feeding component includes a hopper, the hopper is mounted on a support, a housing is fixedly connected to the support, an auger is rotatably connected inside the housing, a first pulley is fixedly connected to one end of the auger, a drive motor is provided below the hopper, the drive motor is fixedly connected to the support, a second pulley is fixedly connected to the output end of the drive motor, the first pulley and the second pulley are driven by a belt, and the hopper is connected to the housing.

[0017] In the above technical solution, when the crushing motor is controlled by the controller, the controller will also control the transmission motor to work. The transmission motor transmits power to the auger through the transmission between the first pulley, the second pulley and the belt. The rotation of the auger will drive the raw material falling from the hopper to move along the direction of the auger axis, thereby conveying the raw material to the body of the gyratory pellet mill for pelletizing. The auger is used for feeding because the auger has stable transportation capacity and strong adaptability, thereby improving the working efficiency of the gyratory pellet mill.

[0018] A further improvement of this utility model is that the first pulley and the second pulley have different diameters.

[0019] By adopting the above technical solution, space can be saved and the volume required by the device can be reduced by setting the diameters of the first pulley and the second pulley to be different.

[0020] A further improvement of this utility model is that a second filter screen is fixedly connected inside the hopper.

[0021] By adopting the above technical solution, a second filter screen is installed inside the hopper to screen the raw materials that can be discharged from the crushing box outlet, so that only the raw materials that meet the conditions can be conveyed to the gyratory pellet mill body through the auger for pelletizing.

[0022] A further improvement of this utility model is that a wear-resistant layer is provided on the surface of the pressure plate, and the material of the wear-resistant layer is tungsten carbide.

[0023] By adopting the above technical solution, a wear-resistant layer is provided on the surface of the pressure plate to protect the pressure plate, extend its service life, and thus improve the working efficiency of the oscillating pellet mill.

[0024] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0025] 1. This utility model provides a gyratory pellet mill with automatic feeding function. When feeding is required, the controller controls the crushing component, processing component, and feeding component to work together to put the raw material into the inlet at the top of the crushing box. At this time, the raw material is processed by the crushing component and falls into the discharge port of the collection box, so that the raw material falls from the discharge port into the feeding component, which then transports the raw material into the gyratory pellet mill body for processing. While the raw material is being crushed, the processing component can collect the dust generated by the crushing, thereby avoiding dust leakage and resource waste. The operation of the crushing component, processing component, and feeding component can prevent large raw materials from entering the gyratory pellet mill body and affecting the use of the gyratory pellet mill body, thereby improving the working efficiency of the gyratory pellet mill body. The working principle of the gyratory pellet mill body is based on gyratory motion and particle adhesion. An electric motor drives the rotating drum to rotate, and a spraying device is used to evenly spray liquid or impregnation solution onto the surface of the material. Meanwhile, the up-and-down vibration of the screen causes the material to roll and tumble continuously on the screen, thereby achieving uniform coating and drying of the particles. The oscillating pellet mill body is a mature technology for pelletizing, so it will not be described in detail in this article.

[0026] 2. This utility model provides a gyratory pellet mill with automatic feeding function. When raw materials need to be crushed, the controller controls the crushing motor to work. The crushing motor drives the crushing roller fixedly connected to its output end to rotate. The rotation of the crushing roller transmits power to the other crushing roller through the meshing gears at one end, so that the symmetrically arranged crushing rollers rotate in opposite directions, thereby crushing the raw materials. When the raw materials enter from the top of the crushing box, the larger raw materials will be crushed by the symmetrically arranged crushing rollers and then fall to the bottom of the crushing box and fall into the feeding component through the discharge port. The operation of the symmetrically arranged crushing rollers can crush the raw materials, thereby improving the working efficiency of the gyratory pellet mill.

[0027] 3. This utility model provides a gyratory pellet mill with automatic feeding function. When the crushing motor drives the crushing roller to rotate, it will drive the cam fixedly connected to it to rotate. The rotation of the cam will squeeze the pressure plate. At this time, the spring is in a stretched state. The gas in the piston cylinder will be transported from the outlet pipe to the collection box through the one-way valve in the outlet pipe. Then the gas passes through the first filter screen, and the dust it carries will be intercepted by the first filter screen and fall into the collection box. The air will enter the crushing chamber through the pipe. When the cam disengages from the pressure plate, the pressure plate will be reset under the action of the spring. The gas with dust in the crushing chamber will enter the piston cylinder through the feed pipe and the one-way valve. When large raw materials are crushed, dust is also generated. This dust will be emitted from the crushing chamber, interfering with the workers. It not only wastes raw materials, but also reduces the working efficiency of the gyratory pellet mill. By setting up a processing component, the dust can be collected, thereby avoiding resource waste and improving the working efficiency of the gyratory pellet mill. Attached Figure Description

[0035] The present invention will be further described in detail below with reference to embodiments:

[0036] Example

[0037] like Figure 1 As shown, this utility model provides a gyratory pellet mill with automatic feeding function, comprising:

[0038] A base 1 is provided, and a swing pellet mill body 2 is fixedly connected above the base 1. A collection box is provided below the swing pellet mill body 2 and is fixedly connected to the base 1. A controller is fixedly connected to one side of the swing pellet mill body 2. A bracket 4 is fixedly connected to the base 1. A crushing box 5 is fixedly connected above the base 1. A crushing motor 6 is fixedly connected to one side of the crushing box 5. A processing box 7 is fixedly connected above the base 1.

[0039] The crushing component is located above the base 1 and is used to crush the raw materials.

[0040] The processing component is located above the base 1 and is used to process the dust generated during the crushing of raw materials.

[0041] The feeding component is located on one side of the crushing component and is used to convey the raw materials to the inlet of the oscillating pellet mill body 2.

[0042] In this embodiment, when feeding is required, the controller controls the crushing component, processing component, and feeding component to work together to put the raw material into the inlet at the top of the crushing box 5. At this time, the raw material is processed by the crushing component and falls into the outlet of the collection box, so that the raw material falls from the outlet into the feeding component, which then transports the raw material into the oscillating pellet mill body 2 for processing. While the raw material is being crushed, the processing component can collect the dust generated by the crushing, thereby avoiding dust leakage and resource waste. The operation of the crushing component, processing component, and feeding component can prevent large raw materials from entering the oscillating pellet mill body 2 and affecting its use, thereby improving the working efficiency of the oscillating pellet mill body 2. The working principle of the oscillating pellet mill body 2 is based on oscillating motion and particle adhesion. An electric motor drives the rotating drum to rotate, and a spraying device is used to evenly spray liquid or impregnation solution onto the surface of the material. Meanwhile, the up-and-down vibration of the screen causes the material to roll and tumble continuously on the screen, thereby achieving uniform coating and drying of the particles. The main body of the oscillating pellet mill 2 is a mature technology for pelletizing, so it will not be described in detail in this article.

[0043] like Figure 2 As shown, in this embodiment, preferably, the crushing component includes a crushing roller 8, which is symmetrically arranged and rotatably connected to the crushing box 5. One end of the crushing roller 8 is fixedly connected to the output end of the crushing motor 6, and the other end of the crushing roller 8 is fixedly connected to a gear 9. The symmetrically arranged gears 9 mesh with each other.

[0044] When raw materials need to be crushed, the crushing motor 6 is controlled by the controller to work. The crushing motor 6 drives the crushing roller 8, which is fixedly connected to its output end, to rotate. The rotation of the crushing roller 8 transmits power to the other crushing roller 8 through the gear 9 meshing with each other at one end, so that the symmetrically arranged crushing rollers 8 rotate in opposite directions, thereby crushing the raw materials. When the raw materials enter from the top of the crushing box 5, the larger raw materials will be crushed by the symmetrically arranged crushing rollers 8 and then fall to the bottom of the crushing box 5 and fall into the feeding component through the discharge port. The operation of the symmetrically arranged crushing rollers 8 can crush the raw materials, thereby improving the working efficiency of the oscillating pellet mill body 2.

[0045] like Figure 4 and Figure 5As shown, preferably, the processing component includes a cam 11 and a piston cylinder 10. The piston cylinder 10 is located on one side of the crushing box 5 and is fixedly connected to the crushing box 5. A piston plate 12 is slidably connected inside the piston cylinder 10. A piston rod 13 is fixedly connected to one end of the piston plate 12. A pressure plate 14 is fixedly connected to the end of the piston rod 13 away from the piston plate 12. A spring 15 is fixedly connected to the side of the piston plate 12 near the piston rod 13. The other end of the spring 15 is fixedly connected to the piston cylinder 10. The cam 11 is fixedly connected to the end of the crushing roller 8 near the gear 9. The cam 11 and the pressure plate 14 work together. A collection box 16 is slidably connected inside the processing box 7. A first filter screen 17 is provided above the collection box 16 and is fixedly connected to the collection box 16.

[0046] When the crushing motor 6 drives the crushing roller 8 to rotate, it drives the cam 11, which is fixedly connected to it, to rotate. The rotation of the cam 11 will squeeze the pressure plate 14. At this time, the spring 15 is in a stretched state. The gas in the piston cylinder 10 will be transported from the outlet pipe to the collection box 16 through the one-way valve in the outlet pipe. Then the gas passes through the first filter screen 17, and the dust it carries will be intercepted by the first filter screen 17 and fall into the collection box 16. The air will enter the crushing chamber 5 through the pipe. When the cam 11 disengages from the pressure plate 14, the pressure plate 14 will be reset under the action of the spring 15. The gas with dust in the crushing chamber 5 will enter the piston cylinder 10 through the feed pipe and the one-way valve. When large raw materials are crushed, dust is also generated along with them. This dust will be emitted from the crushing chamber 5, interfering with the workers. It not only wastes raw materials, but also reduces the working efficiency of the oscillating pellet mill body 2. By setting up a processing component, the dust can be collected, thereby avoiding resource waste and improving the working efficiency of the oscillating pellet mill body 2.

[0047] like Figure 2 As shown, preferably, the feeding component includes a hopper 18, which is mounted on a support 4. A housing 19 is fixedly connected to the support 4. An auger 20 is rotatably connected inside the housing 19. One end of the auger 20 is fixedly connected to a first pulley. A drive motor 21 is provided below the hopper 18. The drive motor 21 is fixedly connected to the support 4. A second pulley is fixedly connected to the output end of the drive motor 21. The first pulley and the second pulley are driven by a belt. The hopper 18 is connected to the housing 19.

[0048] When the crushing motor 6 is controlled by the controller, the controller will also control the transmission motor 21 to work. The transmission motor 21 transmits power to the auger 20 through the transmission between the first pulley, the second pulley and the belt. The rotation of the auger 20 will drive the raw material falling from the hopper 18 to move along the axis of the auger 20, thereby conveying the raw material into the oscillating pellet mill body 2 for pelletizing. The auger 20 is used for feeding because the auger 20 has stable transportation capacity and strong adaptability, thereby improving the working efficiency of the oscillating pellet mill body 2.

[0049] like Figure 1 As shown, preferably, the first pulley and the second pulley have different diameters.

[0050] By setting the diameters of the first and second pulleys to be different, space can be saved and the volume required for the device can be reduced.

[0051] like Figure 2 As shown, preferably, a second filter screen 22 is fixedly connected inside the hopper 18.

[0052] By installing a second filter screen 22 inside the hopper 18, the raw materials that can be discharged from the outlet of the crushing box 5 are screened, so that only the raw materials that meet the conditions can be conveyed to the swing pellet mill body 2 through the auger 20 for pelletizing.

[0053] like Figure 4 As shown, preferably, the surface of the pressure plate 14 is provided with a wear-resistant layer 23, and the material of the wear-resistant layer 23 is tungsten carbide.

[0054] By providing a wear-resistant layer 23 on the surface of the pressure plate 14, the pressure plate 14 can be protected, its service life can be extended, thereby improving the working efficiency of the oscillating pellet mill body 2.

[0055] The working principle of this type of gyratory pellet mill with automatic feeding function will be explained in detail below.

[0056] like Figure 1 - Figure 5As shown, when feeding is required, the controller controls the crushing component, processing component, and feeding component to work together to put the raw material into the inlet at the top of the crushing box 5. At this time, the raw material is processed by the crushing component and falls into the discharge port of the collection box, so that the raw material falls from the discharge port into the feeding component, which then transports the raw material into the gyratory pellet mill body 2 for processing. While the raw material is being crushed, the processing component can collect the dust generated by the crushing, thereby avoiding dust leakage and resource waste. The operation of the crushing component, processing component, and feeding component can prevent large raw materials from entering the gyratory pellet mill body 2 and affecting its use, thereby improving the working efficiency of the gyratory pellet mill body 2. When raw materials need to be crushed, the crushing motor 6 is controlled by the controller to work. The crushing motor 6 drives the crushing roller 8, which is fixedly connected to its output end, to rotate. The rotation of the crushing roller 8 transmits power to the other crushing roller 8 through the gear 9 meshing with each other at one end, so that the symmetrically arranged crushing rollers 8 rotate in opposite directions, thereby crushing the raw materials. When the raw materials enter from the top of the crushing box 5, the larger raw materials will be crushed by the symmetrically arranged crushing rollers 8 and then fall to the bottom of the crushing box 5 and fall into the feeding component through the discharge port. When the crushing motor 6 drives the crushing roller 8 to rotate, it drives the cam 11, which is fixedly connected to it, to rotate. The rotation of the cam 11 will squeeze the pressure plate 14. At this time, the spring 15 is in a stretched state. The gas in the piston cylinder 10 will be transported from the outlet pipe to the collection box 16 through the one-way valve in the outlet pipe. Then the gas passes through the first filter screen 17, and the dust it carries will be intercepted by the first filter screen 17 and fall into the collection box 16. The air will enter the crushing chamber 5 through the pipe. When the cam 11 disengages from the pressure plate 14, the pressure plate 14 will be reset under the action of the spring 15. The gas with dust in the crushing chamber 5 will enter the piston cylinder 10 through the feed pipe and the one-way valve. When large raw materials are crushed, dust is also generated along with them. This dust will be emitted from the crushing chamber 5, interfering with the workers. It not only wastes raw materials, but also reduces the working efficiency of the oscillating pellet mill body 2. By setting up a processing component, the dust can be collected, thereby avoiding resource waste and improving the working efficiency of the oscillating pellet mill body 2. When the crushing motor 6 is controlled by the controller, the controller also controls the drive motor 21 to work. The drive motor 21 transmits power to the auger 20 through the transmission between the first pulley, the second pulley, and the belt. The rotation of the auger 20 causes the raw material falling from the hopper 18 to move along the axis of the auger 20, thereby conveying the raw material into the oscillating pellet mill body 2 for pelletizing. By setting the diameters of the first pulley and the second pulley to be different, space can be saved and the volume required by the device can be reduced.By installing a second filter screen 22 inside the hopper 18, the raw materials exiting from the discharge port of the crushing box 5 are screened, ensuring that only qualified raw materials can be conveyed through the auger 20 to the gyratory pellet mill body 2 for granulation. The wear-resistant layer 23 on the surface of the pressure plate 14 protects the pressure plate 14, extends its service life, and thus improves the working efficiency of the gyratory pellet mill body 2.

[0057] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
