Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of granular material filling, and particularly relates to an automatic filling device for solid particles. BACKGROUND

[0002] Steel balls and other spherical particles are often used for assembling parts such as bearings. After cleaning, the produced steel balls are generally filled into bottles for storage. The number of particles in the bottle is usually marked on the bottle. The qualified products can have a small number of deviations (usually a few more), but the deviation should not be too large.

[0003] For filling a specific amount of steel balls or steel balls, there are two ways of volume counting and weight counting. Each of the above two ways has disadvantages.

[0004] When volume counting, the stacking of steel balls cannot be completely regular, so the gap between steel balls is not the same, and the number of steel balls stored in the same volume at a time is easy to deviate greatly.

[0005] When weight counting, although the accuracy is high, the weight needs to be sensed after filling, and the excess cannot be removed, so the filling is generally filled to 80%, and then a small size feeding nozzle is used for small amount and multiple feeding until the standard is reached, so the overall efficiency is low. SUMMARY

[0006] In view of the above problems, the present application provides a quantitative filling device which can balance efficiency and accuracy. The present application adopts a quantitative method of directly counting steel balls, counts and temporarily stores the material in the gap of the conveying belt, and then quickly fills the material that has been counted. The present application uses magnetic force to release the steel balls above the sector magnet, and counts the steel balls through the rotation angle of the feeding disc.

[0007] Furthermore, when discharging, the sliding of the piston rod not only concentrates the release of the material in the temporary storage cylinder, but also automatically closes the discharging function by increasing the longitudinal distance between the sector magnet and the telescopic slide rod, thereby closing the feeding port during concentrated filling, and counting and temporarily storing the material in the filling gap.

[0008] The technical scheme adopted by the present application is as follows: the present application provides an automatic filling device for solid particles, comprising a rotary disc type counting and discharging assembly, a magnetic discharging assembly, a particle size adaptive adjusting assembly, a temporary storage assembly, a rotary disc driving assembly, a frame type rack and a filling bottle, the rotary disc type counting and discharging assembly is rotationally arranged on the frame type rack, the magnetic discharging assembly is slidingly arranged on the rotary disc type counting and discharging assembly, the particle size adaptive adjusting assembly is rotationally arranged below the rotary disc type counting and discharging assembly, the temporary storage assembly is arranged on the frame type rack, and the rotary disc driving assembly is arranged on the frame type rack.

[0014] When the extension sliding rod rotates above the sector magnet, the extension sliding rod will retract under the action of magnetic force, so as to release the limitation on the steel ball, so that the steel ball enters the temporary storage cylinder through the converging sliding channel under the action of centrifugal force.

[0017] When the blanking piston extends from the temporary storage cylinder, the steel balls in the temporary storage cylinder will fall and enter the filling bottle, and at the same time, the longitudinal distance between the sector-shaped magnet and the telescopic slide rod increases due to the descent of the sector-shaped magnet relative to the temporary storage cylinder along with the piston rod, so that the telescopic slide rod above the sector-shaped magnet will not retract at this time, and at this time, the feeding into the temporary storage cylinder is stopped, thereby achieving control of the single filling quantity.

[0019] By rotating the adjustment code disc, the position of the insulating slide sleeve in the sliding groove can be synchronously adjusted, thereby adapting to steel balls of different diameters, and ensuring that at most one steel ball can be stored in the sector-shaped space of the feeding turntable.

[0020] Further, the turntable driving assembly comprises a rotary driving motor and a driving gear, the rotary driving motor is arranged on the frame rack, the driving gear is arranged on the output shaft of the rotary driving motor, the upper portion of the turntable sleeve portion is provided with an external gear, and the external gear and the driving gear are in meshing transmission.

[0021] Further, the filling bottle is arranged on an external conveying belt, and the inner diameter of the bottle mouth of the filling bottle is between the inner diameter and the outer diameter of the temporary storage cylinder.

[0024] (2) The partition plate divides the feeding turntable into a plurality of independent sector-shaped areas, and at most one steel ball exists in each sector-shaped area through the limitation of the material blocking flange plate.

[0025] (3) When the telescopic slide rod rotates to the upper portion of the sector-shaped magnet, the telescopic slide rod will retract under the action of magnetic attraction, thereby releasing the limiting of the steel ball, so that the steel ball enters the temporary storage cylinder through the converging slide under the action of centrifugal force.

[0026] (4) When the blanking piston extends from the temporary storage cylinder, the steel ball in the temporary storage cylinder will fall and enter the filling bottle, and at the same time, since the fan-shaped magnet descends relative to the temporary storage cylinder along with the piston rod, the longitudinal distance between the fan-shaped magnet and the telescopic slide rod increases, at this time, the telescopic slide rod above the fan-shaped magnet will not retract, at this time, the feeding towards the temporary storage cylinder is stopped, thereby realizing the control of the single filling quantity.

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0042] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0043] like Figures 1-10 As shown, the present invention proposes an automatic filling device for solid particles, including a rotary counting and feeding assembly 1, a magnetic feeding assembly 2, a particle size adaptation and adjustment assembly 3, a temporary storage assembly 4, a rotary drive assembly 5, a frame frame 6, and a filling bottle 7. The rotary counting and feeding assembly 1 is rotatably mounted on the frame frame 6, the magnetic feeding assembly 2 is slidably mounted on the rotary counting and feeding assembly 1, the particle size adaptation and adjustment assembly 3 is rotatably mounted below the rotary counting and feeding assembly 1, the temporary storage assembly 4 is mounted on the frame frame 6, and the rotary drive assembly 5 is mounted on the frame frame 6.

[0044] The number of steel balls fed into the temporary storage cylinder 41 can be controlled and calculated by adjusting the rotation angle of the feeding turntable 11.

[0045] The frame rack 6 is provided with a hollow shaft part 61, the rotary disc type counting and discharging assembly 1 comprises a feeding rotary disc 11, a discharging cabin 12, a feeding pipe 13 and a blocking flange plate 14, the feeding rotary disc 11 is provided with a rotary disc sleeve part 113, the rotary disc sleeve part 113 is rotatably arranged on the hollow shaft part 61, the discharging cabin 12 is clamped at the gap of the blocking flange plate 14, the feeding pipe 13 simultaneously penetrates the upper cover of the discharging cabin 12 and the frame rack 6, and the rotary disc sleeve part 113 is rotatably arranged in the blocking flange plate 14.

[0046] The partition plate 111 divides the feeding rotary disc 11 into a plurality of independent fan-shaped areas, and at most one steel ball exists in each fan-shaped area by the limitation of the blocking flange plate 14.

[0047] The feeding rotary disc 11 is annularly and uniformly provided with the partition plate 111, and the sliding grooves 112 are arranged between the partition plates 111, the magnetic attraction discharging assembly 2 comprises an insulating sliding sleeve 22 and a telescopic sliding rod 23, the insulating sliding sleeve 22 is slidingly arranged in the sliding groove 112, and the telescopic sliding rod 23 is slidingly arranged in the insulating sliding sleeve 22.

[0048] The magnetic attraction discharging assembly 2 further comprises a fan-shaped magnet 21 and an extension reset spring 24, the fan-shaped magnet 21 is arranged on the temporary storage assembly 4, the extension reset spring 24 is arranged between the insulating sliding sleeve 22 and the telescopic sliding rod 23, and the telescopic sliding rod 23 slides downward under the action of the magnetic attraction force when the telescopic sliding rod 23 is close to the insulating sliding sleeve 22.

[0049] When the telescopic sliding rod 23 rotates to the upper side of the fan-shaped magnet 21, the telescopic sliding rod 23 is retracted under the action of the magnetic attraction force, so that the limiting of the steel ball is released, and the steel ball enters the temporary storage cylinder 41 through the converging slide 411 under the action of the centrifugal force.

[0050] The temporary storage assembly 4 comprises a temporary storage cylinder 41 and a discharging piston 42, the temporary storage cylinder 41 is fixedly connected to the frame rack 6, the side surface of the temporary storage cylinder 41 is provided with the converging slide 411, the discharging piston 42 is clamped and slidingly arranged in the temporary storage cylinder 41, the discharging piston 42 is provided with a piston rod 421, the piston rod 421 is clamped and slidingly arranged in the frame rack 6, and the fan-shaped magnet 21 is fixedly connected to the piston rod 421 through a support.

[0051] The temporary storage assembly 4 further comprises a closing spring 43, a top plate 44 and a telescopic guide rod 45, the closing spring 43 is arranged between the piston rod 421 and the frame rack 6, the top plate 44 is arranged at the top of the piston rod 421, and the telescopic guide rod 45 is arranged between the top plate 44 and the frame rack 6.

[0052] When the feeding piston 42 extends from the temporary storage cylinder 41, the steel balls in the temporary storage cylinder 41 fall and enter the filling bottle 7. At the same time, as the sector magnet 21 descends relative to the temporary storage cylinder 41 along with the piston rod 421, the longitudinal distance between the sector magnet 21 and the telescopic slide rod 23 increases. At this time, the telescopic slide rod 23 located above the sector magnet 21 will not retract, and feeding into the temporary storage cylinder 41 stops, thereby achieving control over the number of fillings per batch.

[0053] The particle size adaptation adjustment component 3 includes an adjustment code disk 31 and a linkage rod 32. The linkage rod 32 is rotatably located below the feeding turntable 11. One end of the linkage rod 32 is hinged to the boss of the adjustment code disk 31, and the other end of the linkage rod 32 is hinged to the insulating sleeve 22. When the adjustment code disk 31 rotates, it can synchronously adjust the position of the insulating sleeve 22 in the slide groove 112.

[0054] By rotating the adjustment encoder 31, the position of the insulating sleeve 22 in the slide groove 112 can be adjusted synchronously, thereby accommodating steel balls of different diameters and ensuring that at most one steel ball can be stored in the fan-shaped space of the feeding turntable 11.

[0055] The turntable drive assembly 5 includes a rotary drive motor 51 and a drive gear 52. The rotary drive motor 51 is mounted on the frame 6, and the drive gear 52 is mounted on the output shaft of the rotary drive motor 51. An external gear is provided on the upper part of the turntable sleeve 113, and the external gear and the drive gear 52 mesh and transmit power.

[0056] The filling bottle 7 is located on the external conveyor belt, and the inner diameter of the bottle mouth of the filling bottle 7 is between the inner diameter and the outer diameter of the temporary storage cylinder 41.

[0057] like Figure 11 As shown, the partition 111 divides the feeding turntable 11 into several independent sector areas. By adjusting the position of the telescopic slide bar 23, it can accommodate steel balls of different diameters.

[0058] Area a is the feeding area and overlaps with the unloading bin 12. The steel balls in the unloading bin 12 will enter the fan-shaped space of this area. When the feeding turntable 11 rotates, at most one steel ball will be stored in the fan-shaped space. The stacked steel balls cannot rotate with the material blocking flange 14.

[0059] Region b is the centrifugal zone. During the circular motion of the steel ball in the fan-shaped region, it will tend to resist the telescopic slide bar 23 and move outward.

[0060] The c area is a feeding area and coincides with the sector magnet 21. When the blanking piston 42 is not extended from the temporary storage cylinder 41, the distance between the sector magnet 21 and the feeding turntable 11 is short, at this time, the telescopic slide rod 23 above the sector magnet 21 will retract under the magnetic attraction, so that the steel ball enters the converging slide 411; when the blanking piston 42 is extended from the temporary storage cylinder 41, the distance between the sector magnet 21 and the feeding turntable 11 is far, at this time, the magnetic attraction of the sector magnet 21 cannot overcome the elastic force of the extension reset spring 24 to pull the telescopic slide rod 23, at this time, the feeding is stopped.

[0061] In specific use, the user needs to deliver the steel ball to the blanking cabin 12 through the feeding pipe 13 and drop into the sector space of the feeding turntable 11, and drive the feeding turntable 11 to rotate through the rotary drive motor 51. Since the position of the telescopic slide rod 23 is limited and matched with the diameter of the steel ball, at most one steel ball will be stored in the sector space, and the stacked steel balls will be blocked by the blocking flange plate 14 due to the excessive height.

[0062] The steel ball leaving the blanking cabin 12 will resist the telescopic slide rod 23 under the centrifugal force, and at the same time contact the upper surface of the feeding turntable 11. The rotation angle of the feeding turntable 11 can count the feeding of the steel ball.

[0063] When the material rotates to the upper side of the sector magnet 21, the telescopic slide rod 23 will retract under the magnetic attraction and approach the sector magnet 21, at this time, the steel ball blocked by the telescopic slide rod 23 will enter the temporary storage cylinder 41 under the centrifugal force through the converging slide 411.

[0064] The material is temporarily stored in the temporary storage cylinder 41. After the counting is completed, in the process of continuous rotation of the rotary drive motor 51, the top plate 44 is pushed downward by an external mechanism. First, the temporary storage cylinder 41 will descend with the top plate 44, and after the temporary storage cylinder 41 abuts against the bottle mouth of the filling bottle 7, the temporary storage cylinder 41 cannot continue to descend, at this time, the top plate 44 pushes the blanking piston 42 to descend. On the one hand, after the blanking piston 42 is extended from the temporary storage cylinder 41, the originally temporarily stored material will quickly enter the filling bottle 7 to complete the filling; since the amount of material stored in the temporary storage cylinder 41 is known, the amount of filling can be controlled;

[0065] On the other hand, at the same time, since the sector magnet 21 descends with the piston rod 421 relative to the temporary storage cylinder 41, the longitudinal distance between the sector magnet 21 and the telescopic slide rod 23 increases, at this time, the telescopic slide rod 23 above the sector magnet 21 will not retract, at this time, the feeding towards the temporary storage cylinder 41 is stopped.

[0066] Since the rotation speed of the feeding turntable 11 and the filling amount in the filling bottle 7 are known, by controlling the time interval of the top plate 44, the relative accurate control of the filling amount can be realized.

[0067] The counting and filling operations are alternated, and since the bottles 7 are on the lower conveyor belt, the displacement of the latter takes place during the counting operation, and the time required for the displacement of the conveyor belt should be slightly less than the time required for the counting operation.

[0068] It is to be understood that the phraseology or terminology such as "first" and "second", etc. used herein is merely intended to differentiate one entity or operation from another entity or operation, without necessarily requiring or implying any actual such relationship or order between such entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can also include other elements not expressly listed or inherent to such process, method, article, or apparatus.

[0069] The above description of the application and its embodiments is not restrictive, and the embodiments shown in the drawings are only one of the embodiments of the application, and the actual structure is not limited thereto. In general, if a person skilled in the art is inspired by it, without departing from the purpose of the application, without creative design, similar structure and embodiments of the technical solution can be designed, which should belong to the protection scope of the application.
