Description

Technical Field

[0001] This utility model belongs to the field of sensor manufacturing technology, and specifically relates to a coal powder filling device for the inner cavity of a metal tube. Background Technology

[0002] In the field of sensor manufacturing, some core components of sensors rely on metal tubes as carriers, and coal powder needs to be precisely filled into the inner cavity of the metal tubes to meet subsequent performance requirements. Coal powder is composed of fine particles with tiny gaps and friction between them. When the sensor's metal tube is subjected to external vibration, the coal powder particles will consume some of the vibration energy through "mutual collision and friction," playing a damping role and preventing the sensor's internal sensitive elements from generating "signal overload" due to excessive vibration amplitude. At the same time, it suppresses the "resonance interference" of the metal tube itself (as a rigid structure, the metal tube is prone to resonance at specific frequencies, leading to measurement distortion). The gaps between coal powder particles and the loose structure have a natural "absorption and filtering" effect on high-frequency vibration signals, which can filter out irrelevant high-frequency noise during equipment operation (such as motor electromagnetic noise and pipeline fluid turbulence noise), retaining only the target low-frequency vibration signal and improving measurement accuracy.

[0003] Existing metal tube cavity coal powder filling devices can only process one workpiece at a time. Other operations cannot be carried out simultaneously during the filling process, which directly prolongs the overall working time, resulting in low operating efficiency and making it difficult to adapt to the needs of mass production. At the same time, the existing horizontal blowing method for filling coal powder is prone to coal powder escaping from the gap between the workpiece and the fixing mechanism, which not only wastes raw materials but also generates dust pollution. In addition, uneven airflow distribution can lead to inconsistent coal powder filling in the workpiece cavity, affecting the performance of subsequent sensors. Utility Model Content

[0004] The purpose of this invention is to provide a pulverized coal filling device for the inner cavity of a metal tube, so as to solve the problems that single workpiece filling cannot be carried out in parallel and that the horizontal blowing method will cause pulverized coal to escape, resulting in inconsistent filling volume of the workpiece.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a metal tube inner cavity coal powder filling device, a platform, on which a rotating mechanism and a coal powder feeding mechanism are provided;

[0006] The rotating mechanism includes a first rotating component and multiple fixed blocks, all of which are connected to the top of the first rotating component. The fixed blocks are used to fix the workpiece.

[0007] The pulverized coal feeding mechanism includes a coal cylinder and a second rotating component. The coal cylinder is semi-cylindrical and has a third groove. A disc is connected to the bottom of the coal cylinder, and a fourth groove is opened on the top of the disc. The third groove and the fourth groove are connected. A feeding funnel is provided on the side of the fourth groove near the rotating mechanism. The second rotating component is provided inside the fourth groove, and multiple notches are provided on the second rotating component.

[0008] Furthermore, the side wall of the second rotating component is in contact with the inner cavity of the fourth slot, and the top of the second rotating component is in contact with the bottom of the coal cylinder.

[0009] Furthermore, the third slot is arranged in an arc shape.

[0010] Furthermore, an "L"-shaped connecting platform is connected to the top of the platform, and a second motor is installed on the top of the platform, with the second motor located at the bottom of the connecting platform.

[0011] Furthermore, the end of the output shaft of the second motor passes through the disk and is mounted on the bottom of the second rotating component.

[0012] Furthermore, the bottom outlet of the feeding hopper is located directly above the workpiece to be filled with pulverized coal.

[0013] Furthermore, a groove is provided on the top of the platform, and a No. 1 motor is installed in the groove. The bottom of the No. 1 rotating component is mounted on the output shaft of the No. 1 motor.

[0014] Furthermore, the plurality of fixed blocks are arranged symmetrically around the center of the first rotating component.

[0015] Furthermore, a first groove is formed on the fixing block, and a second groove is formed on both sides of the inner cavity of the first groove. A clamping block is set inside the two second grooves.

[0016] Furthermore, an elastic element is provided between the clamping block and the inner cavity of the second groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This metal tube cavity coal powder filling device can simultaneously clamp multiple workpieces by using multiple fixed blocks on the first rotating part, and allows the coal powder feeding mechanism and the rotating mechanism to run in an alternating manner, so that the continuous feeding of workpieces and coal powder filling are connected in an orderly manner, reducing equipment idle time, greatly improving filling efficiency, and improving the working efficiency of the device.

[0019] This metal tube internal coal powder filling device, by setting up a semi-cylindrical coal cylinder, a second rotating component with a notch, a disc and a feeding funnel, uses the notch to quantitatively contain coal powder, and guides it precisely to the inner cavity of the workpiece through the fourth groove and the feeding funnel, effectively preventing coal powder from spilling and wasting, ensuring that the amount of coal powder filling each workpiece is consistent, and using the gravity of the coal powder to fill it into the workpiece, avoids the problem of coal powder leakage and pollution caused by airflow impact in the traditional horizontal blowing method.

Detailed Implementation

[0027] The present invention will be further described below with reference to the embodiments.

[0028] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0029] Please see Figure 1 and Figure 2This utility model provides a coal powder filling device for the inner cavity of a metal tube, a platform 10, an "L"-shaped connecting platform 110 connected to the top of the platform 10, a coal powder feeding mechanism provided on the top of the connecting platform 110, a rotating mechanism provided on the platform 10, and a workpiece 40 placed on the rotating mechanism.

[0030] Please see Figure 1 , Figure 2 , Figure 5 and Figure 6 The rotating mechanism includes a first rotating component 210 and fixed blocks 220. A groove is provided on the top of the platform 10, and a first motor 230 is installed within the groove. The output shaft of the first motor 230 is vertically upward. The first rotating component 210 is located directly above the groove, and its bottom is mounted on the output shaft of the first motor 230, allowing the first rotating component 210 to rotate with the output shaft of the first motor 230. Four fixed blocks 220 are provided, symmetrically arranged around the first rotating component 210. On the 10, a first groove 2201 is vertically opened on the side of the four fixed blocks 220 that is far away. A second groove 2202 is opened on both sides of the inner cavity of the first groove 2201. A clamping block 221 is set inside the second groove 2202. The clamping block 221 is made of elastic material. An elastic element 222 is set between the clamping block 221 and the inner cavity of the second groove 2202. The elastic element 222 provides the clamping block 221 with the force to move outward out of the second groove 2202. The two clamping blocks 221 are arranged in an arc shape on the side that is close to each other.

[0031] When the workpiece 40 is pressed against the two clamping blocks 221, the two second slots 2202 are arc-shaped and are pressed away from each other by the workpiece 40. When the workpiece 40 contacts the first slot 2201, the two clamping blocks 221 block the workpiece 40 from moving outward under the action of the elastic element 222, so that the workpiece 40 moves with the fixed block 220. The first motor 230 is started, and the output shaft of the first motor 230 drives the first rotating element 210 to rotate. The first rotating element 210 drives the four fixed blocks 220 to pass through the coal powder feeding mechanism one by one.

[0032] Please see Figure 1-4The pulverized coal feeding mechanism includes a coal cylinder 310 and a second rotating component 320. The coal cylinder 310 is semi-cylindrical and has a third groove 3101, which is arc-shaped and used to load pulverized coal. A disc 311 is connected to the bottom of the coal cylinder 310, and a fourth groove 3111 is opened on the top of the disc 311. The third groove 3101 and the fourth groove 3111 are connected, and a feeding funnel 312 is provided on the side of the fourth groove 3111 near the rotating mechanism. The bottom of the feeding funnel 312... The part is located directly above the workpiece 40 to be filled with pulverized coal. The interior of the fourth slot 3111 is equipped with a second rotating component 320. The side wall of the second rotating component 320 is in contact with the fourth slot 3111, and the top of the second rotating component 320 is in contact with the bottom of the coal cylinder 310. The second rotating component 320 is provided with four notches 3201. The top of the platform 10 is equipped with a second motor 330. The second motor 330 is located at the bottom of the connecting platform 110. The output shaft of the second motor 330 passes through the disc 311 and is connected to the second rotating component 320.

[0033] When the second rotating part 320 rotates, the coal powder in the notch 3201 rotates into the feeding funnel 312, and then the coal powder slides into the workpiece 40.

[0034] Motor 1 (230) and Motor 2 (330) operate in an alternating manner.

[0035] The working principle and usage process of this utility model are as follows: The operator aligns the metal tube workpiece 40 to be filled with pulverized coal with the first slot 2201 on the fixing block 220. The two sides of the workpiece 40 respectively abut against the two clamping blocks 221 in the corresponding fixing block 220. Since the clamping blocks 221 are close to each other and are arc-shaped, when the workpiece 40 abuts, it will push the two clamping blocks 221 to move into the second slot 2202, while compressing the elastic element 222. When the workpiece 40 is completely placed into the first slot 2201, the elastic element 222 releases its elastic force, pushing the clamping blocks 221 to move out of the second slot 2202 until the clamping blocks 221 are tightly attached to the outer wall of the workpiece 40, thus completing the fixing of a single workpiece 40.

[0036] Start the power supply to the device, and motor 230 starts running. The output shaft of motor 230 drives rotating component 210 to rotate slowly. Rotating component 210 synchronously drives four centrally symmetrically distributed fixed blocks 220 to rotate, so that the clamped workpieces 40 move one by one to directly below the coal powder feeding mechanism.

[0037] When the first workpiece 40 moves directly below the feeding hopper 312, motor 230 stops running, while motor 330 starts. The output shaft of motor 330 drives rotating component 320 to rotate within slot 3101 of coal cylinder 310. The coal powder in slot 3101 enters the recess 3201 of rotating component 320. As rotating component 320 continues to rotate, the coal powder in recess 3201 slides precisely through the feeding hopper 312 into the inner cavity of workpiece 40 below, completing a single coal powder filling.

[0038] After a single workpiece 40 is filled, motor 330 pauses and motor 230 restarts, driving rotating component 210 to continue rotating, sending the next unfilled workpiece 40 directly below the feeding funnel 312. At the same time, the filled workpiece 40 rotates out of the feeding area with the fixed block 220.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
