[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the description of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0037] It should also be noted that in the embodiments of this application, the same reference numerals are used to represent the same components or the same parts.

It should be understood that the reference numerals are equally applicable to other identical parts or components.

[0038] The embodiments of this application provide a material distributing device, as Figures 1 - 3 shown. The material distributing device includes a storage bin 100 and a material distributing ejector rod 200. The storage bin 100 is used for storing spherical materials (such as freeze-dried balls, pills, ball beads and other spherical objects). An opening 101 is provided at the top of the storage bin 100, and a through hole 102 is provided at the bottom of the storage bin 100. The material distributing ejector rod 200 is movably inserted into the storage bin 100 up and down through the through hole 102. A receiving groove 201 that can only accommodate a single spherical material is provided at the upper end of the material distributing ejector rod 200. The material distributing ejector rod 200 can slide up and down relative to the storage bin 100 so that a single spherical material enters the receiving groove 201 and is pushed up by the material distributing ejector rod 200.

[0039] Specifically, the through hole 102 and the opening 101 are vertically corresponding, and the size of the opening 101 is larger than the size of the through hole 102. The receiving groove 201 is designed as a hemispherical groove, and the diameter of the hemispherical groove is adapted to the diameter of the spherical material, that is, the diameter of two spherical materials > the diameter of the hemispherical groove > the diameter of a single spherical material.

[0040] In the embodiment of the present application, the material distribution device includes a bin 100 for storing spherical materials and a material distribution ejector rod 200 movably passing through the bin 100 through a through hole 102 at the bottom of the bin 100. A receiving groove 201 capable of accommodating only a single spherical material is provided at the upper end of the material distribution ejector rod 200. During use, the material distribution ejector rod 200 is controlled to move up and down in the bin 100. When the upper end of the material distribution ejector rod 200 sinks to the bottom of the bin 100, the upper end of the material distribution ejector rod 200 is submerged in a large number of spherical materials, and a single spherical material can enter the receiving groove 201. The single spherical material entering the receiving groove 201 rises with the material distribution ejector rod 200 and is pushed upward to the opening 101 of the bin 100, realizing the separation of a single spherical material from a large number of spherical materials. Using this material distribution device is simple in operation, high in efficiency, and will not cause the freeze-dried balls to break when separating the freeze-dried balls.

[0041] In addition, the position accuracy of the separated freeze-dried balls is guaranteed, which is beneficial to subsequent automatic packaging.

[0042] In one embodiment, as Figures 3 - 4 shown, the inner diameter of the bin 100 gradually decreases from the opening 101 to the through hole 102.

[0043] Through the above design, under the action of gravity, the freeze-dried balls in the bin 100 can automatically gather towards the middle of the bin 100. Specifically, the inner wall of the bin 100 is an inverted conical surface.

[0044] In one embodiment, as Figure 3 and Figure 5 shown, the upper end of the material distribution ejector rod 200 is provided with a chamfer or a fillet from the edge of the receiving groove 201 to the outer peripheral side of the material distribution ejector rod 200, preventing the freeze-dried balls from being lifted by the part outside the receiving groove 201 at the upper end of the material distribution ejector rod 200, and ensuring that the material distribution ejector rod 200 separates only a single freeze-dried ball each time.

[0045] In one embodiment, as Figures 1 - 3 shown, a linear bearing 300 coaxial with the through hole 102 is provided at the bottom of the bin 100, and the material distribution ejector rod 200 slides through the linear bearing 300.

[0046] By providing the linear bearing 300 to guide the movement of the material distribution ejector rod 200, the stability of the up and down movement of the material distribution ejector rod 200 is improved.

[0047] It can be understood that the linear bearing 300 in this embodiment can also be replaced by a sleeve and a guide sleeve.

[0048] In one embodiment, as Figure 3 and Figure 5As shown, the wall of the receiving groove 201 is provided with a negative pressure suction hole 2011. An air passage 202 is arranged inside the material distributing ejector rod 200. One end of the air passage 202 is communicated with the negative pressure suction hole 2011, and the other end is led out from the lower end of the material distributing ejector rod 200 and can be connected to a negative pressure source through an air pipe joint. The spherical materials located in the receiving groove 201 can be adsorbed in the receiving groove 201 by negative pressure.

[0049] The material distributing ejector rod 200 is designed as a hollow rod. When the material distributing ejector rod 200 runs to the lowest position, the vacuum adsorption mode is turned on to further ensure that the freeze-dried balls in the receiving groove 201 do not fall during the material taking at the lowest point and the rising process.

[0050] In some embodiments, as Figures 1 - 3 shown, the material distributing device further includes a driving device 400. The driving device 400 is connected to the material distributing ejector rod 200 and is used to drive the material distributing ejector rod 200 to reciprocate up and down.

[0051] By driving the material distributing ejector rod 200 to reciprocate up and down through the driving device 400, single freeze-dried balls are continuously separated from a large number of freeze-dried balls. There is no need for manual control of the reciprocating up and down movement of the material distributing ejector rod 200, which reduces the burden on the staff, further improves the material distributing efficiency. At the same time, it is beneficial to the automated design of the material distributing device, and can cooperate with the automatic picking and packaging device to perform the automated packaging operation of the freeze-dried balls.

[0052] In a specific embodiment, as Figures 1 - 3 shown, the driving device 400 includes a driving motor 410 and an eccentric wheel 420 installed on the output shaft of the driving motor 410. The outer peripheral side of the eccentric wheel 420 abuts against the lower end of the material distributing ejector rod 200.

[0053] With the driving device 400 arranged as above, the structure is simple. Just power on the driving motor 410 to drive the eccentric wheel 420 to rotate. By the abutment of the eccentric wheel 420 against the lower end of the material distributing ejector rod 200, the reciprocating lifting movement of the material distributing ejector rod 200 can be realized.

[0054] Among them, the driving motor 410 can adopt a stepping reduction motor. It can be understood that the material distributing ejector rod 200 keeps in contact with the outer peripheral side of the eccentric wheel 420 under its own gravity. To make the contact between the two close and reliable, the weight of the material distributing ejector rod 200 can be increased by adding a counterweight, or the material distributing ejector rod 200 can be made of a metal material.

[0055] It can be understood that in other embodiments, the driving device 400 can also adopt linear driving mechanisms such as a vertically arranged cylinder, electric cylinder, linear motor, etc. to drive the material distributing ejector rod 200 to realize the reciprocating up and down movement.

[0056] In a more specific embodiment, as Figures 1 - 3As shown, a roller 500 is rotatably provided at the lower end of the material distributing ejector rod 200, and the outer peripheral side of the eccentric wheel 420 abuts against the roller 500.

[0057] The lower end of the material distributing ejector rod 200 contacts the outer peripheral side of the eccentric wheel 420 through the roller 500, which can reduce friction and extend the service life, making the lifting movement of the material distributing ejector rod 200 smoother.

[0058] Specifically, the roller 500 can directly adopt a deep groove ball bearing and is installed at the lower end of the material distributing ejector rod 200 through a bracket or the mounting block 700 in the following embodiments.

[0059] In a more specific embodiment, as Figures 1 - 3 shown, the driving motor 410 is installed on the motor fixing seat 430, and an elastic member 600 is provided between the lower end of the material distributing ejector rod 200 and the motor fixing seat 430. The elastic member 600 is used to apply a downward elastic force to the material distributing ejector rod 200.

[0060] Through the cooperation of the elastic member 600 and the self-weight of the material distributing ejector rod 200, the roller 500 is always kept in close contact with the eccentric wheel 420.

[0061] Among them, the elastic member 600 can adopt components such as a tension spring and a rubber band that can provide elasticity.

[0062] Preferably, a mounting block 700 is provided at the lower end of the material distributing ejector rod 200, the roller 500 is arranged on the mounting block 700, and the two opposite sides of the mounting block 700 are respectively connected to the motor fixing seat 430 through an elastic member 600.

[0063] Setting two elastic members 600 on the left and right not only increases the elastic force but also makes the overall force on the material distributing ejector rod 200 uniform, improving the stability of the up and down movement.

[0064] Taking the elastic member 600 as a tension spring as an example, hooks are provided at both ends of the tension spring, hanging ears are provided on both the mounting block 700 and the motor fixing seat 430, and the hooks at both ends of the tension spring are respectively hooked on the hanging ears on the mounting block 700 and the motor fixing seat 430. The lifting of the material distributing ejector rod 200 is controlled by the eccentric wheel 420. Selecting a tension spring for the eccentric wheel 420 ensures that the material distributing ejector rod 200 and the eccentric wheel 420 always remain in contact. The structure is simple and the installation accuracy is low.

[0065] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0066] The above embodiments merely illustrate several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the appended claims.
