Description

Technical Field

[0001] This utility model relates to the technical field of fan shaft core feeding equipment, and in particular to an automatic feeding machine for fan blade injection molding shaft cores. Background Technology

[0002] In the injection molding process of fan blades, the shaft core is a key component, and its precise feeding has a significant impact on product quality and production efficiency. Traditional shaft core feeding mainly relies on manual operation or semi-automatic equipment, which presents the following technical problems:

[0003] Manual arrangement and loading are inefficient, especially for small shafts with a diameter of only 2-3mm. Manual operation is more difficult and prone to errors, such as incorrect shaft orientation or omissions, affecting the injection molding yield. Furthermore, it cannot meet the high-cycle production demands of multi-cavity molds (2-8 products). Semi-automatic equipment uses a single loading method, unable to load multiple shafts, reducing continuous shaft production and resulting in low efficiency.

[0004] Therefore, improvements are needed. Utility Model Content

[0035] In view of the technical problems described in the background art, such as Figure 1-14As shown, an automatic feeding machine for injection-molded fan blade shafts is provided, comprising: a frame 1 for mounting and supporting mechanical components; a vibratory feeder 2 for holding shafts, the vibratory feeder 2 having one or more spirally arranged feeding channels 3; a first screening component 4, the first screening component 4 being adjustablely mounted on the feeding channels 3 by screws, the first screening component 4 being intermittently arranged with the feeding channels 3, and a first channel 5 being provided on the end face of the first screening component 4; a feeding pipe 6, the feeding pipe 6 being one or more, the first port of the feeding pipe 6 being connected to the outlet of the feeding channels 3; and a distributing device 7, the distributing device 7 being mounted on the frame 1, the distributing device 7 including a base block 8, a first telescopic component 9 mounted on the base block 8, and a component disposed on the base block 8 and connected to the first telescopic component. The system includes a moving block 10 connected to the drive end and a bracket 11 mounted on the base block 8; the second port of the feeding pipe 6 is mounted on the bracket 11; the moving block 10 has two or more rows of first discharge ports 12; the base block 8 has a second discharge port 13 corresponding to the first discharge port 12; the moving block 10 is connected to two or more rows of air outlet pipes 14; the lower end face of the base block 8 has a discharge pipe 15; the first end of the discharge pipe 15 is connected to the first discharge port 12; a discharge rack 16 has an adjustable fixing block 17 for connecting the second end of the air outlet pipe 14; a transfer fixture 18 is configured to receive the shaft core on the fixing block 17; and a control system for receiving and sending signals.

[0036] In the above technical solution, the control system can be a PLC, microcontroller, or other device capable of controlling the operation of the equipment. The fan blade shaft is shaped like a mushroom nail at one end and cylindrical at the other, with knurled patterns on the circumference.

[0037] The shaft core is placed inside the vibratory feeder 2. To achieve higher processing efficiency, multiple feeding channels 3 are set inside the vibratory feeder 2. In this embodiment, two feeding channels 3 are described. The shaft core is fed by vibration. Since the shaft core needs to maintain a uniform orientation during feeding, a first screening component 4 is set on the feeding channel 3. The first screening component 4 can be adjusted in position relative to the feeding channel 3 to change the spacing. The first screening component 4 and the feeding channel 3 are intermittently arranged, forming a step. Since the shaft core of the fan blade has a mushroom-shaped head at one end and a cylindrical head at the other end, the first screening component 4 and the feeding channel 3 are intermittently arranged. During production, the mushroom-shaped head of the shaft core is used as the feeding end. When the shaft core is transported to the position of the first screening component 4 in the feeding channel 3 with one end of the mushroom-shaped head, due to the smooth structure of the mushroom-shaped head, it can pass over the first screening component 4 and enter the position of the first channel 5 under the action of vibration and the push of the shaft core behind it. When the shaft core, with one cylindrical end, is transported to the position of the first screening component 4 in the feeding trough 3, under the action of vibration transport, the cylindrical end of the shaft core cannot pass the end face of the first screening component 4 and, pushed by the subsequent shaft cores, falls into the gap between the first screening component 4 and the feeding trough 3, and is re-vibrated for feeding. This achieves forward and reverse identification of the shaft core for feeding, with a forward and reverse identification accuracy rate of ≥99.9%.

[0038] The feeding pipe 6 is in the form of multiple pipes, which can be matched with the feeding channel 3. If there are two feeding channels 3, the feeding pipe 6 can be selected in the form of two or more pipes, which can realize the switching of different specifications of shaft cores.

[0039] The material distribution device 7 is used to distribute shaft cores, enabling the feeding of multiple shaft cores and improving processing efficiency. Specifically, the material distribution device 7 includes a base block 8, a first telescopic component 9, a moving block 10, a support 11, an air outlet pipe 14, and a material outlet pipe 15. The first telescopic component 9 can be a cylinder or other component with telescopic function. The air outlet pipe 14 is connected to an air compressor, and the air outlet pipe 14 is opened and closed under the action of a solenoid valve. In implementation, two rows of first material outlets 12 are provided on the base block 8, and there can be multiple first material outlets 12 in each row. Preferably, the number of first material outlets 12 is connected to the feeding pipe 6. The moving block 10 is provided with the same second material outlets 13 corresponding to the first material outlets 12.

[0040] The feeding channel 3 has two channels. The shaft core enters the feeding pipe 6 through the two feeding channels 3. The second end of the feeding pipe 6 is connected to the bracket 11. The two shaft cores fall from the second end of the feeding pipe 6 to the first outlet 12 of the first row on the moving block 10. At this time, the first outlet 12 of the first row on the moving block 10 is misaligned with the second outlet 13 of the first row on the base block 8. Driven forward by the first telescopic member 9, the moving block 10 is moved forward, aligning the first outlet 12 of the first row on the moving block 10 with the second outlet 13 of the first row on the base block 8. The shaft core falls from the outlet of the first row on the moving block 10 to the second outlet 13 of the first row on the base block 8 and enters the discharge pipe 15. At the same time, the two shaft cores fall from the second end of the feeding pipe 6 to the first outlet 12 of the second row on the moving block 10. The material outlet 12 is misaligned with the second discharge outlet 13 of the second row on the base block 8. The first telescopic member 9 is driven backward, causing the moving block 10 to move backward, aligning the first discharge outlet 12 of the second row on the moving block 10 with the second discharge outlet 13 of the second row on the base block 8. The shaft core falls from the discharge outlet of the second row on the moving block 10 to the second discharge outlet 13 of the second row on the base block 8 and enters the discharge pipe 15. At this time, the first exhaust pipe 14 on the moving block 10 is aligned with the second discharge outlet 13 of the first row on the base block 8, the solenoid valve is opened, and the shaft core in the first exhaust pipe 14 is blown to the position of the fixed block 17 using compressed gas. When the first telescopic member 9 is driven forward again, the second exhaust pipe 14 on the moving block 10 is aligned with the second discharge outlet 13 of the second row on the base block 8, the solenoid valve is opened, and the shaft core in the second exhaust pipe 14 is blown to the position of the fixed block 17 using compressed gas.

[0041] By using the above technical solution, the feeding operation of four shaft cores can be realized by moving the moving block 10 back and forth, which greatly improves the feeding efficiency. Specifically, by adjusting the number of feeding pipes 6, first discharge port 12, second discharge port 13 and air discharge pipe 14, the feeding operation of multiple shaft cores can be realized.

[0042] refer to Figure 7 As shown, the present invention also includes a second screening component 19, which is adjustablely mounted on the feeding channel 3 by screws. The second screening component 19 is intermittently arranged with the feeding channel 3, and a second channel 20 is provided on the end face of the second screening component 19.

[0043] To further improve the accuracy of identifying the front and back of the shaft core, a second screening component 19 is added to the feeding channel 3. The principle of the second screening component 19 is the same as that of the first screening component 4, and will not be described in detail here. By utilizing the combination of the first screening component 4 and the second screening component 19, a dual screening structure is formed, improving the accuracy of identifying the front and back of the shaft core.

[0044] refer to Figure 6-7 As shown, the present invention also includes a screening component 21, which includes a probe 22 installed on one side of the feeding channel 3 and an air blowing pipe 23 installed on one side of the feeding channel 3.

[0045] To further improve the accuracy of forward and reverse identification of shaft cores, an additional screening component 21 was added. Its driving process is as follows: one end of the shaft core has a mushroom-shaped design, and the other end is cylindrical with a knurled pattern on the circumference. Forward and reverse identification is performed based on the differences in surface features (such as reflectivity and texture) between the knurled and mushroom-shaped designs of the shaft core. Shaft cores facing the wrong direction are blown back to the vibrating plate 2 by airflow for re-screening. Specifically, the probe 22 identifies the shaft cores in the feeding channel 3. When it identifies a shaft core with a knurled pattern, indicating an incorrect orientation on the feeding channel 3, air is blown back to the vibrating plate 2 via an external solenoid valve and air compressor connected to the air pipe 23.

[0046] In implementation, there are two feeding channels 3 and four feeding pipes 6. The second end of the feeding pipe 6 is connected to the bracket 11. The feeding pipe 6 is divided into two groups of different sizes. The feeding pipe 6 can be switched to connect with the feeding channel 3 according to the shaft core size.

[0047] The feeding channel 3 is configured with two channels, which can feed two shafts at a time. Since shafts come in different sizes and types during production, four feeding pipes 6 are installed on the bracket 11 to enable quick switching during the production process. Two feeding pipes 6 correspond to one type of shaft, and the other feeding pipe 6 corresponds to another type of shaft. During switching, the feeding pipes 6 are connected to the feeding channel 3 by screws.

[0048] refer to Figure 10 As shown, the feeding pipe 6 is adjustablely mounted on the bracket 11 by screws, and the longitudinal height of the feeding pipe 6 relative to the bracket 11 can be adjusted.

[0049] Since the shaft cores have different lengths, in order to prevent the shaft cores from colliding with the outlet of the feeding pipe 6 when they move and switch on the moving block 10, the feeding pipe 6 can adjust its longitudinal height relative to the bracket 11 to accommodate shaft cores of different lengths.

[0050] like Figure 11-12 As shown, the first discharge port 12 is provided with holes for shaft cores of different sizes to pass through, and the second discharge port 13 is adapted to be provided with holes for shaft cores of different sizes to pass through.

[0051] When four feeding pipes 6 are used, it is possible to switch between two different shaft core specifications for production. For this purpose, the first discharge port 12 and the second discharge port 13 need to be equipped with holes for two different shaft core specifications.

[0052] refer to Figure 14 As shown, the transfer fixture 18 includes a support frame 24, a column 25 mounted on the support frame 24, and a second telescopic member 26 disposed on one side of the column 25; wherein the column 25 is a hollow structure, and the telescopic end of the second telescopic member 26 is placed inside the column 25.

[0053] The transfer fixture 18 is used to transfer the loaded shaft core into the mold. In use, the column 25 on the moving bracket 11 is aligned with the fixed block 17 on the discharge rack 16. Under the blowing of compressed gas from the air outlet pipe 14, the shaft cores are moved to the fixed block 17 through the discharge pipe 15. The fixed block 17 is a hollow structure. Since the hollow structure of the column 25 is aligned with the hollow structure of the fixed block 17, the shaft cores are blown into the hollow structure of the column 25. Under the movement of the external moving device, the transfer fixture 18 moves to the mold position. The second telescopic member 26 can be a cylinder or other component with telescopic function. The second telescopic member 26 drives the shaft core to be pushed from inside the column 25 into the mold for subsequent processing operations.

[0054] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
