Description

Technical Field

[0001] The invention relates to a portable powder quick-releasing device and method, belonging to the field of material feeding devices. Background Art

[0002] In experimental research and related engineering fields, powders often need to be fed quickly and stably. When it comes to mobile equipment and confined spaces, there are also requirements for the drive form and structural dimensions of the powder feeding device.

[0003] Currently, commonly used impeller and spiral powder feeders can achieve rapid powder feeding, but their main structure is too large, taking up a lot of space, and difficult to install and operate in a small space. Furthermore, changes in the feed outlet direction can affect the stability of material release and even cause it to fail. In terms of miniaturization of powder feeding devices, many new forms of powder feeding devices have been significantly optimized. The existing patent with publication number CN107879115A discloses a bubbling pressurized micro-powder feeding device, and the patent with publication number CN1851322A discloses a continuous and pulsed micro-powder feeding device. The above two existing technologies both realize material feeding in any direction, but both cannot realize rapid material feeding, and the feeding amount is usually less than 10g / h. In addition, the existing patent with publication number CN106743511A discloses a propulsion feeding device, and the existing patent with publication number CN102285501A discloses a tangential injection powder feeding device. Both existing technologies can enlarge or reduce the device in proportion to complete material feeding of various magnitudes, and changing the material outlet orientation can realize multi-angle feeding of materials, but the structural space required for the realization of the functions of both is relatively large, and they cannot be used lightly.

[0004] In the field of modern space-constrained devices, especially mobile devices that require rapid material feeding, the complexity of the material release structure and the size of the space are extremely important to the development of the device. However, most existing powder release devices are not suitable for rapid material release during movement. The devices that can release are also relatively complex and occupy a large space, which in turn limits the development of mobile devices. Therefore, to address the problems of existing powder feeding devices being too large in size, occupying too much space, and unable to quickly feed materials in multiple directions, there is an urgent need for a lightweight and rapid powder feeding device that can meet the requirements for rapid material release under different usage conditions. Summary of the Invention

[0005] The present invention is developed to address the issues of existing powder feeding devices, which are oversized, occupy too much space, and cannot rapidly and multi-directionally feed materials. The following provides a brief overview of the present invention to provide a basic understanding of certain aspects of the present invention. It should be understood that this overview is not an exhaustive overview of the present invention. It is not intended to identify key or important aspects of the present invention, nor is it intended to limit the scope of the present invention.

[0006] The technical solution of the present invention:

[0007] Solution 1: A lightweight powder quick release device, including a material storage and releaser, a crushing and material feeder, a microcontroller, a material propeller, a rotary conveyor and a gas regulator. The material storage and releaser is a hollow shell structure with a discharge port on the top; the crushing and material feeder and the material propeller are both arranged inside the material storage and releaser and connected to the rotary conveyor. The gas regulator is connected to the top inner cavity and the bottom inner cavity of the material storage and releaser through pipelines respectively. The gas regulator and the rotary conveyor are respectively connected to the microcontroller. The powder material is arranged in the material storage and releaser. The microcontroller controls the gas regulator to realize the powder material propulsion of the material propeller. Under the propulsion of the material propeller, the powder material passes through the crushing and material feeder and is finally released from the discharge port.

[0008] Preferably, the crushing and material feeder is a spiral crushing and stirring blade, and the upper and lower ends of the spiral crushing and stirring blade are in the form of a double cone.

[0009] Preferably: the rotating transmitter includes a transmission shaft and a rotating motor, one end of the transmission shaft is placed inside the material storage and releaser and is fixedly connected to the crushing and material feeder, the other end of the transmission shaft is fixedly connected to the output end of the rotating motor, and the rotating motor is fixedly installed on the outside of the bottom of the material storage and releaser.

[0010] Preferably: the material pusher includes a piston, which is slidably mounted on the outside of the transmission shaft, and the piston is slidably fitted with the inner wall of the material storage and releaser on all sides, forming a gas storage space between the piston and the material storage and releaser. The gas regulator inputs or discharges gas into or out of the gas storage space through the bottom air inlet hole, adjusts the gas content in the gas storage space, and thereby pushes the piston to move up and down.

[0011] Preferably, the material pusher comprises a sliding sealing connection between the piston and the outer side wall of the transmission shaft, and a sliding sealing connection between the piston and the inner side wall of the material storage and releaser.

[0012] Preferably, the gas regulator also introduces gas into the material storage and release device through the gas inlet hole.

[0013] Solution 2: A portable powder quick release method is implemented based on the portable powder quick release device described in Solution 1, and includes the following steps:

[0014] Step 1. Initialize the microcontroller so that the material pusher is placed at the end position of the material storage and release device;

[0015] Step 2. Based on the characteristics of the powder material and the feeding requirements, use a microcontroller to set the number of revolutions of the rotating motor and a gas regulator to control the valve openings of the top and bottom cavities of the material storage and release device;

[0016] Step 3. Load the powder material from the discharge port. During the loading process, the crusher and material feeder are rotated in the opposite direction by rotating the motor, and the material pusher is moved to the initial position at the same time.

[0017] Step 4. Start the gas regulator to control the gas to be ejected from the gas inlet hole, and at the same time control the gas regulator to allow the gas to enter the gas storage space, thereby driving the material pusher to push the powder material. While the powder material is being pushed, it is crushed and crushed by the bottom rotation of the material feeder, and then mixed with the gas entering from the gas inlet hole. It is then crushed and rotated by the top of the material feeder and stably discharged from the discharge port.

[0018] The present invention has the following beneficial effects:

[0019] 1. The lightweight powder quick-release device of the present invention integrates material storage and device structure into a single unit. By simplifying redundant components, the device's structure is simplified while minimizing its size, meeting the needs of use in confined spaces and achieving a deep integration of material and structure.

[0020] 2. The crushing and material feeder of the present invention can effectively prevent material backlog and release the material quantitatively. The material pusher can ensure the multi-directional feeding of the material and ensure that the powder is accurately and continuously released according to the set amount.

[0021] 3. The present invention controls the gas regulator and the rotary conveyor through a microcontroller, which can change the material feeding speed over a wide range and is suitable for feeding powder materials. It solves the problems of existing powder feeding devices that are too large in size, occupy too much space, and cannot feed materials in multiple directions quickly.

[0025] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention is described below using specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0026] The connections mentioned in the present invention are divided into fixed connections and detachable connections. The fixed connection refers to a non-detachable connection, including but not limited to conventional fixed connection methods such as hem connection, rivet connection, adhesive connection, and welding connection. The detachable connection refers to but not limited to conventional detachable connection methods such as threaded connection, snap connection, pin connection, and hinge connection. When the specific connection method is not clearly specified, it is assumed that at least one connection method can always be found among the existing connection methods to achieve the function. Those skilled in the art can choose according to their needs. For example, a welded connection is selected for a fixed connection, and a hinge connection is selected for a detachable connection.

[0027] Specific implementation method 1: Combination Figure 1-Figure 2 The present embodiment is described. A portable powder quick release device of the present embodiment comprises a material storage and releaser 1, a crushing and material feeder 2, a microcontroller 3, a material propeller 4, a rotary conveyor 5 and a gas regulator 6. The material storage and releaser 1 is a hollow shell structure with a discharge port 11 on its top. The crushing and material feeder 2 and the material propeller 4 are both arranged inside the material storage and releaser 1 and connected to the rotary conveyor 5. The gas regulator 6 is connected to the top inner cavity and the bottom inner cavity of the material storage and releaser 1 through a pipeline. The gas regulator 6 and the rotary conveyor 5 are respectively connected to the microcontroller 3. The powder material is arranged in the material storage and releaser 1. The microcontroller 3 realizes the powder material propulsion of the material propeller 4 by controlling the gas regulator 6. Under the propulsion action of the material propeller (4), the powder material passes through the crushing and material feeder 2 and is finally released from the discharge port 11.

[0028] The gas inlet holes 12 are four arranged at 90° on the release outlet side of the material storage and releaser 1. During operation, the gas coming out of the gas inlet holes 12 mixes with the material, which can prevent the material from accumulating at the discharge port and avoid the situation where the material cannot be discharged.

[0029] The crushing and material feeder 2 is a spiral crushing and stirring blade. The upper and lower ends of the spiral crushing and stirring blade are in the form of a double cone. The double cone located at the outlet end is a material quantitative conveying device. The material delivery amount can be adjusted by the rotation speed. The double cone located in the middle and upper part is at the vent of the material storage and releaser. During the material delivery process, it is ensured to be mixed with the gas to prevent the material from piling up. The double cone located at the bottom is the crushing part of the material. Through the rotation of the internal spiral crushing and stirring blade, the force of moving the material toward the outlet is applied, which can effectively transport the material to the delivery part. The spiral crushing and stirring blade is connected to the rotating conveyor as the power source of the crushing and material feeder 2.

[0030] The rotating transmitter 5 includes a transmission shaft 51 and a rotating motor 52. One end of the transmission shaft 51 is placed inside the material storage and releaser 1 and is fixedly connected to the crushing and material feeder 2. The other end of the transmission shaft 51 is fixedly connected to the output end of the rotating motor 52. The rotating motor 52 is fixedly installed on the outside of the bottom of the material storage and releaser 1. The rotating motor 52 is placed at the tail end of the material storage and releaser 1, which minimizes the space occupied by the device and simplifies the device structure.

[0031] The material pusher 4 includes a piston 41, which is slidably mounted on the outside of the transmission shaft 51, and the piston 41 is slidably fitted with the inner wall of the material storage and releaser 1 on all sides. A gas storage space is formed between the piston 41 and the material storage and releaser 1, and the gas regulator 6 inputs or discharges gas to the gas storage space through the bottom air inlet 13 to adjust the gas content in the gas storage space, thereby pushing the piston 41 to move up and down. When gas is introduced, the volume of the gas storage space increases, pushing the material pusher 4, squeezing the material storage space so as to complete the release of materials in multiple directions. The transmission shaft 51 is a circular light rod with a through hole at the center of the piston 41, and the two are slidably fitted. The material pusher 4 and the inside of the material storage and releaser 2, as well as the contact part of the material pusher 4 and the rotating transmitter 5 are provided with a double-channel O-ring sealing structure to ensure the sealing state of the tail space of the material storage and releaser 1, so that the gas introduced into the cavity can maintain the pressure stability and maintain the force of the material pusher.

[0032] The material pusher 4 includes a piston 41 and an outer side wall of the transmission shaft 51, which are connected in a sliding and sealing manner. The piston 41 and the inner side wall of the material storage and releaser 1 are connected in a sliding and sealing manner.

[0033] The gas regulator 6 also introduces gas into the material storage and release device 1 through the gas inlet hole 12 .

[0034] The microcontroller 3 is placed at the bottom of the material storage and releaser 1. Making the two into a unified whole can minimize the space volume occupied by the device and meet the needs of installation in a limited space. The microcontroller 3 sets the motor speed of the rotating motor 52 to complete the crushing and quantitative feeding of the material, and sets the gas valve opening of the gas regulator 6 to control the gas input amount at the tail of the storage and releaser 1, which can continuously generate a force on the material toward the outlet to ensure that the outlet direction changes the material. The gas valve opening of the gas regulator 6 is set to control the gas input amount at the outlet of the storage and releaser 1 to ensure the continuous and stable feeding of the material. The microcontroller 3 transmits signals to the rotating transmitter 5 and the gas regulator 6 respectively.

[0035] Specific implementation method 2: Combination Figure 1-Figure 2 This embodiment describes a portable powder rapid release method, which is implemented based on the portable powder rapid release device described in the first embodiment, and includes the following steps:

[0036] Step 1. Initialize the microcontroller 3 so that the material pusher 4 is placed at the end position of the material storage and release device 1;

[0037] Step 2. Based on the characteristics of the powder material and the feeding requirements, the microcontroller 3 is used to set the number of revolutions of the rotary motor 52 and the gas regulator 6 to control the valve openings of the two gas sources entering the top and bottom cavities of the material storage and release device 1;

[0038] Step 3. Load the powder material from the discharge port 11. During the loading process, the crushing and material feeder 2 is rotated in the reverse direction by the rotating motor 52, and the mobile material pusher 4 is placed in the initial position.

[0039] Step 4. Start the gas regulator 6 to control the gas to be ejected from the gas inlet hole 12, and at the same time control the gas regulator 6 to allow the gas to enter the gas storage space, thereby driving the material pusher 4 to push the powder material. While the powder material is being pushed, it is crushed by the bottom rotation of the material feeder 2, and then mixed with the gas entering from the gas inlet hole 12, and then stably discharged from the discharge port 11 under the action of the crushing and material feeder 2 top rotation.

[0040] It should be noted that in the above embodiments, as long as the technical solutions are not contradictory, they can be permuted and combined. Those skilled in the art can exhaust all possibilities based on the mathematical knowledge of permutations and combinations. Therefore, the present invention will no longer describe the technical solutions after permutations and combinations one by one, but it should be understood that the technical solutions after permutations and combinations have been disclosed by the present invention.

[0041] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
