Description

Technical Field

[0001] This utility model belongs to the field of pyrotechnics technology, specifically relating to an automatic vacuum feeding device for raw materials. Background Technology

[0002] Currently, most pyrotechnic charging processes in China rely on manual feeding, followed by repackaging after the materials are loaded into a temporary storage bin. This method has the following drawbacks:

[0003] 1. During manual material loading, operator safety is difficult to guarantee. Because manual loading involves close contact between operators and pyrotechnic materials, the required safety distance is insufficient. Furthermore, operator errors are possible, creating significant safety hazards on the production line that threaten both operator safety and the protection of the production line itself.

[0004] 2. Manual operation is time-consuming and inefficient. Currently, manual operation typically takes 10-20 minutes. Utility Model Content

[0005] The purpose of this invention is to solve the above-mentioned problems by providing an automatic vacuum feeding device for raw materials. This feeding device can achieve automatic feeding by remote operation of the operator, avoiding close contact between the operator and the pyrotechnic materials during feeding and preventing possible errors. This ensures the safety of the production line and the operator, increases the reliability of feeding, solves the problem of operators working in dangerous places and dangerous processes for a long time, and shortens the feeding time, thereby improving production efficiency.

[0006] To achieve the above objectives, this utility model provides an automatic vacuum feeding device for raw materials, including a positioning mechanism for positioning a fixed structure, a three-axis module for driving a vacuum generator to move along the X, Y and Z directions, a vacuum generator connected to the three-axis module, a conveying pipe and a vacuum suction pipe, one end of the conveying pipe being connected to one end of the vacuum generator, and the other end of the vacuum generator being connected to one end of the vacuum suction pipe.

[0007] As a further optimization, the positioning mechanism is provided with a locking structure for fixing the structure to be fixed.

[0008] As a further optimization, the locking structure is a lever cylinder, which locks or unlocks the structure to be fixed by means of the locking arm on the lever cylinder.

[0009] As a further optimization, the positioning mechanism includes a positioning seat, which has at least one fixing position. One side of the fixing position has a notch to facilitate the entry of the structure to be fixed. Guide wheel sets are symmetrically arranged on the inner walls of the opposite sides of the fixing position.

[0010] As a further optimization, the guide wheel assembly includes two opposing connecting walls, and the guide wheel assembly is connected to a fixed position through the connecting walls. Multiple guide wheels are rotatably connected between the two opposing connecting walls.

[0011] As a further optimization, the triaxial module consists of three linear modules, which are divided into a Y-axis linear module, a Z-axis linear module, and an X-axis linear module due to different installation directions. The slider of the Y-axis linear module is provided with a first fixed seat. The Z-axis linear module is connected to the Y-axis linear module through the first fixed seat. The slider of the Z-axis linear module is provided with a second fixed seat. The X-axis linear module is connected to the Z-axis linear module through the second fixed seat. The slider of the X-axis linear module is provided with a third fixed seat. The vacuum generator is connected to the X-axis linear module through the third fixed seat.

[0012] Advantages and beneficial effects of this utility model

[0013] 1. The feeding device in this utility model, combined with the temporary storage hopper, enables automatic vacuum feeding of various raw materials. This avoids close contact with pyrotechnic materials during manual feeding and prevents potential operational errors, ensuring the safety of operators and equipment and increasing the reliability of feeding.

[0014] 2. The feeding device in this utility model is connected to the control system. The operator can remotely control the movement of the three-axis module in the X, Y, and Z directions via the control system, ensuring that the vacuum suction pipe below the vacuum generator is accurately inserted into the raw material bin in the feeding trolley. Then, the control system inputs positive pressure to the vacuum generator, causing the raw material in the bin to be sequentially drawn through the vacuum suction pipe, vacuum generator, and conveying pipe into the upper temporary storage hopper, achieving automated feeding. Taking a 100kg raw material bin as an example, the feeding time using the feeding device in this application is approximately 5 minutes, significantly reducing feeding time and improving production efficiency compared to manual feeding.

[0015] 3. This utility model achieves human-machine isolation and safe production in hazardous areas. It has a simple structure, is easy to operate, and saves human resources. Attached Figure Description

[0026] In this embodiment, the structure to be fixed is described using the loading trolley 7 as an example.

[0027] like Figure 1 and Figure 2As shown, an automatic vacuum feeding device for raw materials includes a positioning mechanism 1, a three-axis module 2, a vacuum generator 3, a conveying pipe 4, and a vacuum suction pipe 5. The positioning mechanism 1 is used to position the feeding trolley 7. The three-axis module 2 is used to drive the vacuum generator 3 to move along the X, Y, and Z directions. The upper end of the vacuum generator 3 is connected to the lower end of the conveying pipe 4 and locked by a clamp. The upper end of the conveying pipe 4 extends through the bottom plate of the temporary storage hopper 9 into the temporary storage hopper 9. The lower end of the vacuum generator 3 is connected to the upper end of the vacuum suction pipe 5 and locked by a clamp. The lower end of the vacuum suction pipe 5 is inserted into the raw material bucket 8 on the feeding trolley 7 by the movement of the three-axis module 2.

[0028] like Figures 4-6 As shown, the positioning mechanism 1 includes a positioning seat 11, which is formed by three sides of an inverted U-shaped channel steel. In this embodiment, in order to leave two fixed positions 14, an isolation plate 15 is provided in the middle of the positioning seat 11. The fixed positions 14 can be determined according to the actual working conditions, and there can be one or more. In order to facilitate pushing the loading trolley 7 into the fixed position 14 to fix its position, a notch 12 is left on the rear side of the fixed position 14. Guide wheel sets 13 are symmetrically provided on the inner walls of the left and right sides of each fixed position 14.

[0029] like Figure 5 and Figure 6 As shown, the front side of the fixed position 14 is provided with a locking structure 6 for fixing the loading trolley 7. In this embodiment, the locking structure 6 is a lever cylinder. The lever cylinder has a locking arm 61 on the side opposite to the loading trolley 7. The lever cylinder cooperates with the crossbeam at the front end of the loading trolley 7 through the locking arm 61 to lock or unlock the loading trolley 7.

[0030] like Figure 6 As shown, the guide wheel assembly 13 includes two horizontally arranged connecting walls 131. The guide wheel assembly 13 is connected to the side walls on the left and right sides of the fixed position 14 through the connecting walls 131. Multiple guide wheels 132 are rotatably connected between the two opposing connecting walls 131. The guide wheel assembly 13 facilitates the pushing of the loading trolley 7 into the fixed position 14.

[0031] like Figure 3As shown, the three-axis module 2 consists of three linear modules, all of which are existing technologies, model number CF68-L10-S900-BR. Due to different installation directions, they are divided into a Y-axis linear module 21, a Z-axis linear module 22, and an X-axis linear module 23. The Y-axis linear module 21 is mounted on a hopper support 91 below the temporary storage hopper 9, and a first fixed seat 211 is provided on the slider of the Y-axis linear module 21. The Z-axis linear module 22 is connected to the Y-axis linear module 21 via the first fixed seat 211. When the motor on the Y-axis linear module 21 operates, it drives the lead screw or conveyor belt inside the Y-axis linear module 21, thereby causing the slider on it to move along the Y-axis, and ultimately driving the Z-axis linear module 22 to move along the Y-axis via the first fixed seat 211. The slider of the Z-axis linear module 22 is provided with a second fixed seat 221. The X-axis linear module 23 is connected to the Z-axis linear module 22 through the second fixed seat 221, and the Z-axis linear module 22 can drive the X-axis linear module 23 to move along the Z-axis. The slider of the X-axis linear module 23 is provided with a third fixed seat 231, and the vacuum generator 3 is connected to the X-axis linear module 23 through the third fixed seat 231. Through the three-axis movement of the triaxial module 2, the vacuum suction pipe 5 at the lower end of the vacuum generator 3 can be inserted into the raw material barrel 8.

[0032] The motor, vacuum generator 3, and lever cylinder on the triaxial module 2 are all connected to the control system.

[0033] Work process

[0034] 1. First, move the raw material barrel 8 onto the loading trolley 7, and push the loading trolley 7 to the positioning mechanism 1. With the help of the guide wheel group 13, the loading trolley 7 is smoothly pushed into the fixed position 14.

[0035] 2. The operator exits the feeding device, returns to the control room, and uses the control system to control the locking arm 61 on the lever cylinder to lock the feeding trolley 7.

[0036] 3. The control system controls the three-axis module 2 to run according to the program and inserts the vacuum suction pipe 5 into the raw material barrel 8.

[0037] 4. The control system inputs positive pressure to the vacuum generator 3, and uses the vacuum pressure generated by the vacuum generator 3 to suck up the raw materials in the raw material tank 8.

[0038] 5. The raw materials are sequentially transported to the temporary storage silo 9 through the vacuum suction pipe 5, the vacuum generator 3, and the conveying pipe 4.
