A three-cam feeding device

Abstract

This application discloses a three-cam feeding device. When quantitative loading is required, the three-cam feeding device disclosed above operates by feeding external materials into a fixed-volume dosing slot. A transverse cam drives the slot in linear motion, discharging the material from the dosing slot to form a quantitative feed. Once the quantitative feed enters the discharge nozzle, the lower cam first drives the nozzle to a designated discharge position. The upper cam then drives the pressure plate to push the material, causing the material in the nozzle to be discharged to the designated discharge position, ultimately achieving quantitative loading.

Description

Technical Field

[0001] The present application relates to the technical field of quantitative filling of particles, and in particular to a three-cam feeding device. Background Art

[0002] The quantitative loading of sealed particles requires avoiding direct contact with the outside world, which would cause particle contamination and waste, while also enabling high-speed loading. Traditionally, loading of particles has relied on manual loading, which has been inefficient. These two quantitative separation methods have the following main disadvantages: 1. Complex operation. 2. Small particles contain dust, which can be easily inhaled and cause personal injury. 3. Low operational efficiency. Summary of the Invention

[0003] In view of this, the present application provides a three-cam feeding device that can better realize the directional loading of external feeding.

[0004] The present application provides a three-cam feeding device, comprising:

[0005] The quantitative tank is used to store the materials entering from the outside in a fixed volume;

[0006] The transverse cam is used to drive the quantitative groove to move linearly;

[0007] A discharge nozzle, connected to the quantitative groove to receive the feed discharged from the quantitative groove;

[0008] A lower cam is used to drive the discharge nozzle to move linearly;

[0009] The pressing plate is used to push the materials in the discharge nozzle;

[0010] The upper cam is used to drive the pressing plate to move linearly to produce a pushing action.

[0011] Optionally, a cover plate feeding trough is further included to accommodate external feeding to be discharged into the quantitative trough.

[0012] Optionally, the upper cam is connected to the pressure plate via a connecting aluminum block.

[0017] Optionally, the lower guide rod is passed through the bottom structural plate.

[0018] Optionally, a bolt group for fixing with an external drive device is also included.

[0019] The three-cam feeding device disclosed above, when quantitative filling is required, external feed enters the fixed-volume feed slot. The transverse cam drives the slot in linear motion, discharging the feed from the slot to form a quantitative feed. After the quantitative feed enters the discharge nozzle, the lower cam first drives the nozzle to move to the designated discharge position. Then, the upper cam drives the pressure plate to push the material, and the feed in the nozzle is discharged to the designated discharge position, thus achieving quantitative filling of the material.

In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present application.

In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art will appreciate the application of other processes and / or the use of other materials.

[0032] refer to Figure 1-Figure 3 The three-cam feeding device disclosed in this embodiment includes a cover plate feeding chute 4, on which an upper cam 1 is mounted. The upper cam 1 is connected to a pressure plate connecting aluminum block 2, which is fixed to a pressure plate 3. The pressure plate 3 is used to push the material. A guide block 10 is fixed to the pressure plate 3. A guide rod 11 passes through the guide block 10 so that the guide rod 11 supports the guide block 10. The lower side of the upper guide rod 11 is fixed to the bottom structural plate 7.

[0033] The cover plate feed chute 4, the middle structural plate 5, and the bottom structural plate 7 are stacked in sequence. Two transverse guide rods 8 extend through the bottom structural plate 7. A metering chute 9 is sleeved on the transverse guide rods 8 and driven by a transverse cam 6 for linear motion. When material is fed into the cover plate feed chute 4, the transverse cam 6 pushes the metering chute 9 to store the material in a fixed quantity and push it above the discharge nozzle 14.

[0034] The lower cam 13 is fixed to the discharge nozzle 14 to drive the discharge nozzle 14 to move linearly to a specified discharge position, such as a position close to an external storage device. At this time, the pressing plate 3 is then driven downward by the external drive device to push the material out.

[0035] The lower guide rod 12 passes through the bottom structural plate 7 and is used to support the linear motion of the discharge nozzle 14 .

[0036] The three cams of the three-cam feeding device, namely the lower cam 13, the upper cam 1 and the transverse cam 6, are powered by an external device (not shown in the figure), and the power is connected to the external drive device through a bolt group 18.

[0037] As an example, the lower cam 13, the upper cam 1 and the transverse cam 6 of the three-cam feeding device can be phase-changed by an external drive track, and the movement timing can be changed by adjusting the track.

[0038] Here, the three-cam feeding device is connected to an external drive device with a bolt assembly 18, and multiple devices are arranged simultaneously to improve efficiency. At the same time, the external drive device for changing direction drives the upper cam 1, the transverse cam 6, and the lower cam 13 to move linearly, realizing the functions described above.

[0039] Please refer to Figure 4 The external driving device drives the transverse cam 6 along the first direction 15 (ie Figure 4 ) moves, driving the upper cam 1 along the second direction 16 (i.e. Figure 4 ) moves, driving the lower cam 13 along the third direction 17 (i.e. Figure 4 (downward) movement shown in FIG.

[0040] In some typical embodiments, the bottom structural plate 7 is fixed to an external drive device via a bolt assembly 18. External material is fed into the cover plate feed slot 4 and subsequently enters the metering slot 9. Since the empty volume of the metering slot 9 is constant, once material is fed, the transverse cam 6 drives the metering slot 9 in a first direction 15, thereby discharging the material in a predetermined amount toward the feed nozzle 14.

[0041] It can be imagined that the metering groove 9 is driven to a position where it docks with the pressure plate 3, for example, directly below the pressure plate 3. At this time, the lower cam 13 drives the external track to move the discharge nozzle 14 to the discharge position, that is, close to the external filling equipment. Then the pressure plate 3 presses the material down under the drive of the upper cam 1 to produce pushing material for filling.

[0042] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in this application should be covered by the scope of protection of the present application.
