DETAILED DESCRIPTION

[0031] The present application provides a rotary material supply device.

[0032] Embodiment 1: See also Figure 1 A rotary material supply device includes: a support frame 1 and an upper box 11 and a lower box 12 arranged on the support frame 1, and the upper box 11 and the lower box 12 are connected to each other. A feed hopper 111 is arranged on the top of the upper box 11, and the feed hopper 111 is used to put materials into the upper box 11. A first-level unloading component is arranged in the upper box 11; a plurality of second-level unloading components 4 are arranged between the support frame 1 and the lower box 12. After the material is put into the upper box 11, the material falls onto the first-level unloading component, and the amount of material falling into the lower box 12 can be accurately controlled by the first-level unloading component; after the material falls into the lower box 12, the amount of material discharged can be more accurately controlled by the second-level unloading component 4, thereby realizing accurate unloading to meet the unloading requirements and not easily causing material waste.

[0033] See also Figure 2 and Figure 3 In addition, a diffusion hopper 112 is provided on the inner top wall of the upper box 11. When the material is put into the upper box 11, the material flows through the diffusion hopper 112 so that the material can diffuse and fall onto the first-level material discharge assembly.

[0034] See also Figure 1 Furthermore, the outer walls of the upper box 11 and the lower box 12 are fixedly provided with a vibration motor 13. During the unloading process, the vibration motor 13 is started to prevent the material from sticking to the inner walls of the upper box 11 and the lower box 12.

[0035] See also Figure 1 and Figure 3 The first-level blanking component includes: a driving part 2 and a blanking part 3.

[0036] See also Figure 3 The material discharge part 3 includes: a rotating shaft 31, two arc-shaped plates 32 and a plurality of material discharge plates 33. The rotating shaft 31 is rotatably mounted in the upper box 11 and is arranged horizontally. The material discharge plates 33 are fixed on the rotating shaft 31 and are evenly distributed along the circumference of the rotating shaft 31, that is, a grid is formed between two adjacent material discharge plates 33 to receive materials. The arc-shaped plates 32 are fixed on the inner side wall of the upper box 11. The two arc-shaped plates 32 are respectively located at the two ends of the upper box 11 along the width direction, and there is a gap between the two arc-shaped plates 32 for material circulation.

[0037] See also Figure 1 The driving part 2 includes: a driving gear 21, a driven gear 22 and a driving motor 23. The driving motor 23 is mounted on the support frame 1, and the output shaft of the driving motor 23 is coaxially fixed with the driving gear 21. The driven gear 22 is coaxially fixed with one end of the rotating shaft 31 close to the driving motor 23, and the driving gear 21 is meshed with the driven gear 22. After the material falls between the unloading plates 33, the driving motor 23 is started to drive the driving gear 21 to drive the driven gear 22 and the rotating shaft 31 to rotate in turn, so that the unloading plates 33 rotate; until the material rotates to the gap between the two arc-shaped plates 32, the material can automatically fall into the lower box 12 to achieve the effect of precise control of unloading.

[0038] See also Figure 4 The secondary unloading assembly 4 includes: a rotating shaft 41, a spiral blade 42, a rotating gear 43, a rotating gear 44, a control motor 45, a tray 46, a transition pipe 47 and a discharge pipe 48. The discharge pipe 48 is fixed on the support frame 1 and is located below the lower box 12. One end of the transition pipe 47 is connected to the lower box 12, and the other end is connected to the discharge pipe 48. The control motor 45 is installed on the support frame 1, and the output shaft of the control motor 45 is coaxially fixed with the rotating gear 43.

[0039] See also Figure 4One end of the rotating shaft 41 is rotatably mounted in the lower box 12, and the other end penetrates the top wall of the lower box 12 and extends outward and is coaxially fixed with the rotating gear 44, and the rotating gear 43 is meshed with the rotating gear 44. The end of the rotating shaft 41 away from the control motor 45 extends into the transition pipe 47; the spiral blade 42 is fixed to the end of the rotating shaft 41 located in the lower box 12. After the material falls into the lower box 12, the control motor 45 is started to drive the rotating gear 43 to drive the rotating gear 44 and the rotating shaft 41 to rotate in turn. At this time, the spiral blade 42 accurately controls the amount and continuously feeds the material into the discharge pipe 48, and finally discharges it from the discharge pipe 48.

[0040] See also Figure 4 The tray 46 is fixed on one end of the rotating shaft 41 away from the control motor 45. Since the material has low viscosity, the material is easy to flow down automatically and cannot be controlled. At this time, when material needs to be unloaded, the tray 46 rotates with the rotating shaft 41 to unload the material, so that the amount of unloading can be controlled to achieve precise unloading.

[0041] See also Figure 4 Furthermore, in this embodiment, the spiral directions of the spiral blades 42 on adjacent rotating shafts 41 are opposite. The use of spiral blades 42 with different rotation directions can prevent materials from being easily accumulated in the lower box 12, thereby facilitating smoother material unloading.

[0042] The working principle of the first embodiment is as follows: start the driving motor 23 to drive the driving gear 21 to drive the driven gear 22 and the rotating shaft 31 to rotate in turn, so that the unloading plate 33 rotates; until the material rotates to the gap between the two arc plates 32, the material can automatically fall into the lower box 12 to achieve the effect of precise control of unloading.

[0043] Embodiment 2: See also Figure 5 The difference between this embodiment and the first embodiment is that a uniform drop component is provided between the rotating shaft 31 and the upper box 11. When the material is put into the upper box 11, the uniform drop component can assist the diffusion bucket 112 to make the material fall more evenly and diffusely between the adjacent unloading plates 33, so that the material is not easily accumulated in one place, resulting in the inability to accurately control the unloading amount or even the inability to unload the material.

[0044] See also Figure 5 , Figure 6 and Figure 7 The evenly falling component includes: a receiving part 5, a transmission part 7 and a shaking part 6.

[0045] See also Figure 7 and Figure 8The receiving part 5 includes: a receiving plate 51, a supporting tube 52, a supporting rod 53 and a sliding rod 54. The receiving plate 51 is arranged in the upper box 11, and the two ends of the receiving plate 51 along the width direction are arc-shaped so that the receiving plate 51 can rotate; the supporting tube 52 is fixed to the inner wall of the end of the upper box 11 away from the driving motor 23, one end of the supporting rod 53 is fixed to the receiving plate 51, and the other end is telescopic in the supporting tube 52, and the supporting rod 53 is cylindrical.

[0046] See also Figure 5 and Figure 7 One end of the sliding rod 54 is fixed to the end of the receiving plate 51 away from the support rod 53, and the other end penetrates the upper box 11 and extends outward. When the material is put into the upper box 11, the material falls onto the receiving plate 51; at this time, the sliding rod 54 is used to pull the receiving plate 51 to move back and forth in the horizontal direction, so that the material on the receiving plate 51 can be more evenly accumulated on the receiving plate 51 (a small amount of material will fall from both ends of the receiving plate 51 along the length direction during the movement, which is not considered).

[0047] See also Figure 5 and Figure 7 The shaking unit 6 includes: a vertical plate 61, a rotating rod 62, a rotating disk 63 and a shaking rod 64. The vertical plate 61 is fixed on the support frame 1 and is located on the side of the sliding rod 54 away from the receiving plate 51; the rotating rod 62 is vertically rotatably installed on the side wall of the vertical plate 61 close to the sliding rod 54, and the rotating rod 62 is coaxially fixed with the rotating disk 63. One end of the shaking rod 64 is rotatably installed on the top wall of the rotating disk 63, and the other end is rotatably installed on the sliding rod 54. After the material falls on the receiving plate 51, the rotating rod 62 is driven to drive the rotating disk 63 to rotate, so that the shaking rod 64 can pull the sliding rod 54 to move back and forth in the horizontal direction to shake the material on the receiving plate 51 to be uniform.

[0048] See also Figure 7 and Fig. 9 The transmission part 7 includes: a coaxial rod 71, a control rod 72, an extension rod 73, a connecting rod 74, a connecting spring 75, a transmission gear 76 and a connecting gear 77.

When the control rod 72 rotates, the transmission gear 76 will drive the connecting gear 77, the rotating rod 62 and the rotating disk 63 to rotate in turn, so that the shaking rod 64 can pull the sliding rod 54 to reciprocate in the horizontal direction.

[0050] See also Figure 7 and Fig. 9 The end of the connecting rod 74 away from the connecting spring 75 is provided with an inclined connecting guide surface 741, and the end of the connecting guide surface 741 close to the connecting spring 75 extends out of the connecting hole 722. After the material is shaken evenly, the rotating shaft 31 is controlled to rotate in the opposite direction; at this time, through the setting of the connecting guide surface 741, the connecting rod 74 is automatically pressed into the accommodating hole 731, so as to no longer form a limit on the coaxial rod 71 and the control rod 72, so that the coaxial rod 71 no longer drives the control rod 72 to rotate, that is, the receiving plate 51 is no longer shaken, thereby facilitating subsequent material unloading.

[0051] See also Fig.10 The uniform falling component includes: a falling part 8 and a linkage part 9.

[0052] See also Fig.11 The blanking part 8 includes: a slide plate 81, a slider 82, a screw 83, a screw barrel 84 and a coil spring 85.

After the material is shaken evenly, the screw barrel 84 is driven to rotate. The rotation of the screw barrel 84 can drive the screw 83 to rise, so as to push the receiving plate 51 to flip, so that the material can fall from the receiving plate 51 to the blanking plate 33.

[0053] See also Fig.10 and Fig.12The linkage part 9 includes: a driving rod 91, a linkage rod 92, an insertion rod 93, a limiting rod 94, a limiting spring 95, a transmission belt 96, a first gear 97 and a second gear 98.

[0054] See also Fig.10 and Fig.12 The end wall of the linkage rod 92 close to the driving rod 91 is provided with an insertion hole 921, and the inner wall of the insertion hole 921 is provided with a limiting hole 922; one end of the insertion rod 93 is fixedly connected to the driving rod 91, and the other end is arranged in the insertion hole 921.

In the process of shaking the material evenly, the limiting rod 94 is automatically pressed into the placement hole 931 through the setting of the limiting guide surface 941, so that the driving rod 91 only rotates idle; when the control rotating shaft 31 rotates in the opposite direction, the limiting rod 94 is inserted into the limiting hole 922 to limit the driving rod 91 and the linkage rod 92, so that the driving rod 91 will drive the linkage rod 92, the first gear 97, the second gear 98 and the screw barrel 84 to rotate in sequence, and the rotation of the screw barrel 84 will drive the screw 83 to move upward.

[0056] See also Fig.10 The coil spring 85 is sleeved on one end of the screw barrel 84 located in the mounting hole, and one end of the coil spring 85 is fixed to the screw barrel 84, and the other end is fixed to the inner wall of the mounting hole. After the material on the receiving plate 51 is lowered, the control rotating shaft 31 drives the control rod 72 to rotate again; at this time, the coil spring 85 restores its deformation to automatically drive the screw barrel 84 to rotate, thereby driving the screw rod 83 to move downward to restore the receiving plate 51 to a horizontal state.

[0057] The working principle of the second embodiment is as follows: after the material falls onto the receiving plate 51, the driving rotating rod 62 drives the rotating disk 63 to rotate, so that the shaking rod 64 can pull the sliding rod 54 to move back and forth in the horizontal direction to shake the material on the receiving plate 51 to make it uniform.

[0058] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
