Example 1
Referring to fig. 1-3 in combination, the present embodiment discloses a vertical powder feeder 1000, which includes a storage container 0100, a material guiding pipe 0200, an intermittent screw axis 0310 and a continuous screw axis 0410, and is used for realizing uniform and environment-friendly feeding of powder or powder particle mixture.
The magazine 0100 is for storing raw materials containing powder components. The raw material containing the powder component may be a pure powder or a mixture of powder and particles. Storage vessel 0100 is in a wide variety of forms including hoppers, cylinders, bins, etc.
Referring to fig. 3-6 in combination, exemplary storage vessel 0100 further includes a binning plate 0110 for dividing the storage chamber of storage vessel 0100 into at least two flow channels. Wherein each flow passage is communicated with the intermittent screw shaft 0310. Alternatively, each flow channel is provided with a corresponding intermittent screw axis 0310. Each flow channel may be used to transport a different material, with the flow channels forming a one-to-one relationship with the material.
Illustratively, the storage vessel 0100 further includes a throttle control 0120 for controlling the flow through each flow path to achieve a desired ratio of ingredients by controlling the ratio of the mixed materials. Illustratively, the throttle controller 0120 may include a throttle shaft 0121 and a throttle plate 0122 disposed on the throttle shaft 0121. The throttle shaft 0121 rotates to enable the throttle plate 0122 to rotate to a corresponding angle, and the throttle plate 0122 regulates the flow area of the flow channel to control the flow rate. Wherein, throttle pivot 0121 can be through motor drive, also can be through adjustment handle 0123 drive.
Illustratively, the dividing plate 0110, the throttle controller 0120 and the intermittent screw shaft 0310 are sequentially arranged from top to bottom along the vertical direction, so as to avoid the impact of the entering material on the intermittent screw shaft 0310 caused by direct falling.
The shape of the magazine 0100 is also varied, such as a cylinder, a cuboid, a cone or other shaped. Illustratively, the bottom of magazine 0100 has a prismatic or frustoconical configuration that is large up and small down. It will be appreciated that the land or table configuration has a radial configuration with the small end down and the large end up, allowing the material to be gradually gathered from top to bottom.
Wherein, the pyramid stand refers to a part between the bottom surface of the pyramid and one section. In a preferred embodiment, the land is the portion between the base of the pyramid and a section parallel to the base. The small end of the pyramid is the end of the pyramid with the larger cross-sectional area.
The truncated cone is a part between the bottom surface and the section obtained by removing the truncated cone by a plane parallel to the bottom surface of the cone. The round table has a shaft, a bottom surface, a side surface and a bus as well as a cylinder and a cone, and the letter of the shaft of the round table is used for representing the round table. The small end of the truncated cone means the end of the cone having a smaller cross-sectional area taken by the vertical plane of its axis.
The material guiding pipe 0200 is used for connecting the material storage container 0100 with the hopper of the injection molding machine, providing a closed place for conveying raw materials, avoiding powder leakage and ensuring better environmental protection. In other words, the input end of feed conduit 0200 is connected to storage vessel 0100 and the output end is connected to the injection molding machine hopper. Exemplarily, the material guiding pipe 0200 is a rigid pipe, which does not deform to avoid lateral bending of the hose structure, so that the conveying channel is kept stable, and blocking caused by lateral congestion is avoided. Further, guide tube 0200 is a rigid straight tube.
The intermittent screw shaft 0310 is rotatably held in the magazine 0100 and has intermittent screw blades 0312 for effecting the transfer of material from the magazine 0100 to the input of the feed pipe 0200. It should be understood that the intermittent helical shaft 0310 refers to the intermittent distribution of its helical blades on the shaft, forming the intermittent helical blades 0312 described above.
The intermittent screw shaft 0310 includes a first rotating shaft 0311 and intermittent screw blades 0312, and the intermittent screw blades 0312 are disposed on an outer circumferential surface of the first rotating shaft 0311 and have an intermittent distribution structure. Illustratively, the first rotating shaft 0311 is a rigid shaft, and the intermittent helical blades 0312 are rigid blades, so as to avoid distortion and blockage caused by deflection deformation of the soft structure.
Further, the first rotary shaft 0311 is also connected to a first driving source 0320, forming a first shaft system 0300. The first driving source 0320 is implemented in a plurality of ways, including a rotary motor, a hydraulic motor, and the like, which can output a rotary motion.
Illustratively, intermittent helical blade 0312 is formed by a fracture of a helical blade that remains continuous, with a partial removal. In other words, the intermittent helical blade 0312 has a plurality of mutually unconnected helical segments, and is coaxially disposed on the first rotary shaft 0311.
The first rotating shaft 0311 rotates and drives the intermittent helical blades 0312 thereon under the driving of the first driving source 0320. Intermittent helical blades 0312 (e.g., helical sections therein) act on the raw materials in storage vessel 0100, causing the raw materials to undergo helical rotational motion along the axial direction of first rotational shaft 0311, and the raw materials are stirred and mixed and gradually approach the input end of feed conduit 0200, thereby achieving mixed transfer.
Wherein the spiral rotation motion of the raw material contains centrifugal motion components to generate centrifugal force. The interaction force between the insufficiently mixed powder materials or between the powder materials and the granular materials is insufficient to overcome the centrifugal force, so that centrifugal movement occurs, and separation occurs at the break-off part between the spiral sections for screening. After the screening effect, the raw materials reaching the input end of the material guiding pipe 0200 reach a fully mixed and uniformly distributed composition structure. Thereafter, the concentration of the uniform raw material in the material guiding pipe 0200 is better, and the better conveying efficiency and injection molding quality are ensured.
It will be appreciated that as the number of helical segments increases, a multi-stage screening and mixing action may be created, further increasing the degree of mixing uniformity of the feedstock reaching the input end of conduit 0200. It will be appreciated that as the spacing between adjacent helical segments increases, the material being screened increases simultaneously.
Exemplarily, the intermittent screw shaft 0310 is arranged horizontally, i.e. its axial direction remains horizontal. The purpose is that the dead weight of the raw materials is utilized to further drive the raw materials which are not fully and uniformly mixed to fall down in the disconnection part of the adjacent spiral section, thereby improving the screening effect.
Further, a discharging end is provided on a side wall of the storage container 0100, the discharging end is communicated with the material guiding pipe 0200, and the intermittent screw shaft 0310 penetrates through the discharging end. In other words, the raw material fed through the intermittent screw shaft 0310 enters the input end of the guide pipe 0200 through the discharge end.
Illustratively, feed conduit 0200 is connected to magazine 0100 by transition feed mount 0600. In other words, the conversion feeding seat 0600 has a conversion input end and a conversion output end, the conversion input end is connected with the discharge end of the storage container 0100, and the conversion output end is connected with the input end of the material guiding pipe 0200. The transition input is illustratively held perpendicular to the transition output.
Illustratively, transition feed stock 0600 includes a clean close plate 0610. The clean shrouding 0610 detachably sets up on converting feeding seat 0600 to operating personnel clear up converting feeding seat 0600's inside cavity, guarantees better result of use. It should be appreciated that the storage vessel 0100, the transition seat 0600 and the feed conduit 0200 each have good sealing properties and are sealingly connected at the junction to avoid leakage of the feedstock.
Further, the intermittent screw shaft 0310 is located at the bottom of the storage container 0100, so that both the intermittent screw shaft 0310 and the raw material can fully act, and an ideal acting coverage is provided. In particular, in the embodiment in which the intermittent screw shaft 0310 is horizontally disposed at the bottom of the storage container 0100, the material dropped from the intermittent screw shaft 0310 is screened out and accumulated at the bottom of the storage container 0100, which is closer to and far away from the intermittent screw shaft 0310, so that the intermittent screw shaft 0310 can directly act on the intermittent screw shaft in the subsequent process, so that continuous conveying can be realized, and the action range is increased to avoid the accumulation omission of the material caused by too far distance.
A continuous helical shaft 0410 is rotatably held within conduit 0200 and has continuous helical blades 0412 for effecting transfer of feedstock from the input end of conduit 0200 to its output end. In other words, continuous helical axis 0410 extends longitudinally through the input and output ends of feed conduit 0200. Illustratively, continuous helical axis 0410 is disposed coaxially with guide tube 0200.
Wherein, the intermittent screw axis 0310 and the continuous screw axis 0410 (specifically, the axial directions of the two) have a non-zero included angle therebetween. In other words, the two are not parallel to each other, and the conveying direction of the raw material is changed. The angle of the non-zero included angle is selected according to practical application requirements, such as acute angle, obtuse angle and the like. The non-zero right angle is illustratively a right angle. For example, in the embodiment in which the intermittent screw axis 0310 is horizontally arranged as described above, the continuous screw axis 0410 is vertically arranged.
Illustratively, the continuous helical shaft 0410 includes a second rotating shaft 0411 and continuous helical blades 0412, the continuous helical blades 0412 being disposed on an outer circumferential surface of the second rotating shaft 0411 and having a continuous distribution structure. In other words, the helical structure of the continuous helical blade 0412 is intersected along the axial direction of the second rotation axis 0411, and the structure is kept consistent. Illustratively, the second rotating shaft 0411 is a rigid shaft, and the continuous helical blade 0412 is a rigid blade, so as to avoid distortion and blockage caused by deflection deformation of the soft structure.
Further, the second rotation shaft 0411 is also connected to a second driving source 0420, forming a second shaft system 0400. The second drive source 0420 is implemented in numerous ways, including a rotary electric machine, a hydraulic motor, etc. of the type of device that can output rotary motion.
The second rotating shaft 0411 rotates and drives the continuous spiral blades 0412 thereon to rotate under the driving of the second driving source 0420. The continuous helical blade 0412 acts on the feed material fed from the input end of feed conduit 0200 to cause a helical rotational movement of that portion of the feed material, which is further mixed and fed to the output end of feed conduit 0200.
Illustratively, the end of feed tube 0200 remote from storage vessel 0100 has a discharge tube 0500, with discharge tube 0500 being connected to or held opposite the injection molding machine hopper at one end and held opposite continuous helical blade 0412 at the other end. Under the centrifugal action, the raw materials on the continuous spiral blades 0412 are centrifugally thrown out and enter a discharge pipe 0500, and are conveyed to a hopper of the injection molding machine through the discharge pipe 0500. Illustratively, the discharge tube 0500 is a rigid straight tube, maintaining good transfer efficiency.
The positional relationship between the discharge pipe 0500 and the guide pipe 0200 depends on the practical application environment. Illustratively, the discharge tube 0500 has an acute included angle with the direction of gravity. In other words, the discharge pipe 0500 is inclined downward, so that the raw material flows downward under the action of dead weight in a further acceleration manner, and the output efficiency is improved.
