DETAILED DESCRIPTION

[0043] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0044] It should be noted that the illustrations provided in this embodiment are only used to illustrate the basic concept of the present invention in a schematic manner. Therefore, the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0045] See also Figures 1 to 3As shown, the present invention proposes a feeding device and a feeding method thereof to improve the existing powder packaging, which often has too many dispersed steps and different efficiencies of each workstation, resulting in low overall production capacity. For example, in the feeding and barreling process, the dry powder in the barrel often falls unevenly, and the weighing process is complicated, which requires manual intervention, and wastes a lot of subsequent production time. Specifically, the feeding device 100 includes a feeding component 10 and a weighing component 20. The weighing component 20 is arranged on one side of the feeding component 10. Independent roller lines are set on the feeding component 10 and the weighing component 20. The independent roller line 101 is used to transfer the barrel 101. The feeding component 10 is used to inject materials into the barrel 101, and the weighing component 20 is used to weigh the barrel 101.

[0046] See also Figure 1 and Figure 2 As shown, in this embodiment, the feeding assembly 10 includes a frame 11, a double-channel linear vibration trough 12, a material drop channel 13 and a distributor 14. The double-channel linear vibration trough 12 is arranged on the frame 11, the material drop channel 13 is installed on the frame 11, and the distributor 14 is installed on one end of the material drop channel 13 close to the double-channel linear vibration trough 12. In this embodiment, the double-channel linear vibration trough 12 includes two material troughs 121, and the two material troughs 121 have different sizes, for example, the two material troughs 121 have different widths to provide different charging speeds, and the distributor 14 is used to distribute materials into the two material troughs 121.

[0047] See also Figure 1 and Figure 2 As shown, in this embodiment, the material distributor 14 includes a material distributor body, a material distributor plate and a first drive motor. A feed port and two discharge ports are formed on the material distributor body. The feed port is connected to the drop channel 13. The two discharge ports correspond to one end of the two material troughs 121, respectively, so as to inject materials into the two material troughs 121, and then load the materials into the barrel 101 through the material troughs 121. The material distributor plate is rotatably installed in the material distributor body. The first drive motor is connected to the rotating shaft of the material distributor plate, and is used to drive the material distributor plate to rotate, so that during the injection process, the incoming PTFE material is broken up and discharged evenly. It can be understood that the axis of the rotating shaft of the material distributor plate is arranged parallel to the length direction of the material trough 121, so as to realize the injection of materials into the two material troughs.

[0048] See also Figure 1 and Figure 2As shown, in this embodiment, a slope 1211 is provided at the bottom of one end of the material trough 121 close to the distributor 14, and the discharge port of the distributor 14 points to the slope 1211. For example, an inclined inclined plate may be provided at the bottom of one end of the material trough 121 close to the distributor 14 to form the slope 1211, or the bottom of one end of the material trough 121 close to the distributor 14 may be provided with the slope 1211. The slope 1211 can prevent the PTFE from agglomerating when the material is dropped.

[0049] See also Figure 1 and Figure 2 As shown, in the present embodiment, the feeding assembly 10 further includes a flap assembly 15, and the flap assembly 15 is arranged at the outlet of the material trough 121, that is, at one end of the material trough 121 away from the distributor 14, and the flap assembly includes a shell, a flap 151 and a second drive motor, the shell is connected to the double-channel linear vibration trough 12, and its internal chamber is connected to the outlet of the material trough 121, the flap 151 is rotatably connected to the shell, and the second drive motor is connected to the rotating shaft of the flap for driving the flap to rotate, and the rotating shaft of the flap is arranged parallel to the width direction of the material trough 121, so that during the injection process, the incoming PTFE material is broken up and discharged evenly.

[0050] It is understandable that when the above-mentioned flap and the material distributor are controlled to remain stationary in a horizontal position, they can close the discharge port of the distributor 14 and the outlet of the material trough 121, thereby stopping the injection of materials into the barrel.

[0051] See also Figure 1 and Figure 3 As shown, in this embodiment, the weighing assembly 20 is arranged on one side of the frame 11, and is used for weighing in the process of loading materials into the barrel 101. The weighing assembly 20 includes a bracket 21, a roller line 22, a weighing platform 23 and a blocking mechanism 24. The roller line 22 and the weighing platform 23 are arranged on the bracket 21. The roller line 22 is used to realize the transportation of the barrel 101. The weighing platform 23 includes a weighing sensor for weighing the barrel 101. The blocking mechanism 24 is arranged on the bracket 21 and is located on the roller line 22. The outlet of the drum line 22 is used to limit the movement of the barrel 101. When the barrel 101 is transferred to the weighing component 20, the blocking rod 241 of the blocking structure 24 extends out to block the barrel 101 and keep it on the weighing component 20. After the weighing platform 23 weighs and peels, the feeding device 10 is opened to load the barrel 101. When the weighing component 20 weighs and finds that the barrel 101 is full, the feeding component 10 stops, and the blocking rod 241 of the blocking structure 24 retracts to release the restriction on the barrel 101, and the barrel 101 is transferred away through the drum line 22.

[0052] See also Figure 1 and Figure 2 As shown, in this embodiment, the feeding device 100 further includes a reweighing component 30, which is disposed on a side of the weighing component 20 away from the frame 11. It can be understood that the reweighing component 30 has the same or similar structure as the weighing component 20, and is used to reweigh the loaded barrel 101 to check whether it is qualified.

[0053] See also Figures 1 to 3 As shown, in this embodiment, a control component is also included, which is electrically connected to the double-channel linear vibration trough 12, the distributor 14, the flap assembly 15, the weighing assembly 20 and the re-weighing assembly 30, and is used to control the double-channel linear vibration trough 12, the distributor 14, the flap assembly 15, the weighing assembly 20 and the re-weighing assembly 30.

[0054] See also Figures 1 to 4 As shown, in this embodiment, the present invention further proposes a feeding method for a feeding device, which is applied to the feeding device 100 described in the above embodiment, and specifically includes the following steps:

[0055] S1. Control the movement of the roller line to transfer the barrel to the weighing assembly and perform the first weighing. The controller controls the roller line on the frame 10 and the roller line on the weighing assembly 20 to transfer the empty barrel 101 to the weighing assembly 20, so that the barrel mouth of the barrel 101 corresponds to the outlet of the trough 121, and perform the first weighing.

[0056] S2, receiving the empty barrel in place signal sent from the weighing component after the first weighing, opening the feeding component according to the empty barrel in place signal to load the barrel, wherein both the large and small troughs of the double trough linear vibration trough are opened; the weighing component 20 peels the tares after the first weighing, and sends the empty barrel in place signal to the control component, the controller receives the empty barrel in place signal sent from the weighing component 20 after the first weighing, and opens the feeding component 10 according to the empty barrel in place signal to load the barrel, wherein both the large and small troughs 121 of the double trough linear vibration trough 12 are opened, and load the barrel 101 with maximum efficiency. At this time, the material dividing plate and the flap are also controlled to be opened to break up the incoming PTFE material so that it can be discharged evenly.

[0057] S3, receiving a first signal from the weighing component that the weighing result reaches a first threshold, and controlling the closing of the larger of the two troughs of the double-trough linear vibration trough according to the first signal, and continuing to load materials into the barrel through the smaller trough; the weighing component 20 continues to weigh during the process of loading materials into the barrel 101, and sends a first signal to the controller when the weight of the barrel 101 reaches the first threshold. The controller receives the first signal, and controls the closing of the larger of the two troughs 121 of the double-trough linear vibration trough 12 according to the first signal, and continues to load materials into the barrel 101 through the smaller trough, so as to accurately control the weight of the materials loaded into the barrel 101.

[0058] S4. Receive a second signal from the weighing component that the weighing result reaches a second threshold value, and control the closing of the feeding component to stop loading according to the first signal; the weighing component 20 continues to weigh during the loading process of the barrel 101, and when the weight of the barrel 101 reaches the second threshold value, the second signal is sent to the controller. The controller receives the second signal and controls the closing of the feeding component 10 to stop loading according to the second signal.

[0059] S5. Control the movement of the roller line to transfer the loaded barrel to the reweighing component, and transfer it to the subsequent process if it passes the reweighing. After stopping the loading, the controller controls the blocking mechanism on the weighing component 20 to release the limit on the barrel 101, and transfers it to the reweighing component 30 for reweighing through the roller line. After passing the reweighing, release the limit on the barrel 101 by the blocking mechanism on the reweighing component 30, and transfer it to the subsequent process. It should be noted that when the filled barrel is transferred to the reweighing component 20, the next empty barrel is transferred to the weighing component 20 through the roller line 111 on the frame 11, so as to load the next barrel 101 and realize the automated loading process. In this embodiment, a pushing mechanism can be designed on the frame 11 to push the barrel 101 onto the weighing component 20.

[0060] It is understandable that, in the process of automatic loading, after the current barrel is filled and transported away, the subsequent empty barrels continue to enter the weighing component 10 and are loaded, thereby realizing automatic loading and transportation. However, when the weighing component 20 sends the empty barrel in place signal during the first weighing, since the weight of the barrel 101 may fluctuate, the weighing threshold for sending the empty barrel in place signal after the first weighing can be set to a certain range, within which it can be considered to meet the requirements.

[0061] Of course, in other embodiments, the transfer direction of the barrel 101 can be opposite, that is, it is transferred from the external roller line to the weighing component 20 for loading. After being filled with material, it is pushed to the roller line at the bottom of the frame 10 through the pushing mechanism and transferred away. At this time, a weighing platform can be designed under the roller line at the bottom of the frame 10 as a re-weighing component 30.

[0062] The present invention provides a feeding device and a feeding method thereof. The PTFE after passing through the vibrating screen flows out to a double-channel linear vibration trough. The vibration trough receives an empty barrel in place signal from a weighing station. The large and small vibration troughs are fully opened and quickly fed. When the weighing and metering unit feeds back a signal that it is about to be full, the large vibration trough is closed, and the small vibration trough is slowly fed until it is fully weighed. After being full, the large and small vibration troughs stop vibrating, and the full barrel material quickly passes through the weighing and metering unit, and the subsequent empty barrel is peeled. Then the large and small vibration troughs continue to be opened for feeding. After the full barrel material passes through the weighing and metering station, it enters the re-weighing station in turn. After the re-weighing is qualified, the empty barrel is transported downward for transportation. The entire device has a delicate and compact structure and a modular design, and can be set in various powder packaging scenarios. At the same time, through the design of the large and small troughs, the two troughs start loading together at the beginning to improve the loading efficiency. When it is almost full, only the small trough remains to ensure the accuracy of the charging weight.

[0063] The present invention proposes a feeding device and a feeding method thereof. By arranging an inclined surface at the bottom of one end of a material trough close to a distributor, and the discharge port of the distributor points to the inclined surface, PTFE can be prevented from agglomerating when it is dropped. At the same time, by arranging a dividing plate in the distributor and a flap assembly at the outlet of the material trough in the dividing body, the incoming PTFE material can be scattered so that it can be discharged evenly.
