Description

Technical Field

[0001] This utility model relates to the field of automatic feeding technology, and in particular to a disc feeding mechanism. Background Technology

[0002] In industrial automation, particularly in precision assembly and manufacturing, the stability and reliability of automated material feeding equipment are crucial. Vibratory feeders, currently the most widely used automatic feeding mechanism, use vibration and directional tracks to sort and transport large quantities of bulk parts. However, vibratory feeder technology has certain limitations in practical applications.

[0003] First, its working principle relies on an electromagnet to drive the feed trough to generate high-frequency micro-amplitude vibrations, which cause the parts to move directionally along the spiral feed trough. This process generates continuous and relatively large working noise, causing noise pollution to the working environment.

[0004] Secondly, for certain materials with specific shapes, high surface finish requirements, or soft textures, the reciprocating vibration mode of the vibratory feeder cannot achieve rapid, orderly, and stable feeding. These parts may become entangled or jammed during vibration, leading to feeding interruptions and affecting the overall production line efficiency.

[0005] Furthermore, a more prominent issue is the intense friction, collision, and scratching between parts and between parts and the feed channel within the vibratory feeder. This continuous mechanical action easily creates scratches, indentations, or wear on the surface of the parts—a risk of "scratching." For consumer electronics components with stringent appearance quality requirements or high-precision mechanical parts, such damage is unacceptable, leading to decreased material yield and increased production costs.

The outer silo body is fixed on the chassis, and the inner silo body is located inside the outer silo body and connected to the inclined flange. The inclined slinger moves in a circle along the center of the inner silo body. The inner diameter of the guide silo body is larger than the outer diameter of the inner silo body, so that the bottom of the guide silo body is inserted into the inner silo body. Multiple support connectors connected to the outer silo body are fixed on the circumference of the outer wall of the guide silo body. The bottom of the guide silo body is provided with a top cover. The discharge channel extends from the inside to the outside along the circumferential side wall of the guide silo body.

[0016] The disc feeding mechanism described in this invention, through its unique structural design, effectively overcomes the aforementioned shortcomings of traditional vibratory feeder feeding, bringing significant beneficial effects:

[0017] 1. The feeding mechanism uses an inclined disc to feed material in a circular motion around the center, which avoids the working noise generated by the high-frequency micro-vibration of the vibrating disc, creating a quieter and more comfortable working environment for the staff and effectively reducing noise pollution.

[0018] 2. For materials with specific shapes, high surface finish requirements, or soft textures, this mechanism can achieve rapid, orderly, and stable material feeding through its unique material throwing method. When the tilting disc rotates, the parts move towards the discharge channel under centrifugal force, reducing the possibility of parts tangling or jamming and ensuring the stability of the overall production line efficiency.

[0019] 3. The disc feeding mechanism significantly reduces the intense friction, collision, and scratching between parts and between parts and the feed channel. Since the parts mainly move by centrifugal force rather than the reciprocating vibration of the vibrating disc, it effectively avoids the risk of scratches, indentations, or wear on the surface of the parts, thereby improving material yield and reducing production costs.

[0025] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0026] like Figure 1 , Figure 2 and Figure 3As shown, this embodiment provides a sling feeder mechanism, which includes a chassis 10, a cylindrical hopper 20, an inclined sling feeder 30, a discharge channel 40, a drive assembly 50, and an inclined shaft 60.

[0027] The upper surface of the chassis 10 is provided with a sloping flange 70, and multiple support rods 101 are arranged around the bottom circumference of the chassis 10. The feeding mechanism of the tilting disc is fixed to the corresponding automated production equipment through the support rods 101. The cylindrical silo 20 is fixed to the upper surface of the chassis 10, and the tilting disc 30 is located inside the cylindrical silo 20 and moves in a circular motion around the center of the cylindrical silo 20. The discharge channel 40 is set on the side wall of the cylindrical silo 20 along the throwing direction of the tilting disc 30, and the inlet of the discharge channel 40 is located at the apex of the tilting disc 30 when it rotates. The side wall of the discharge channel 40 is provided with an elastic roller 401 that contacts the end face of the inclined slinger 30. The elastic roller 401 ensures the stability of the inclined slinger 30 when it rotates, and avoids the problem of unstable fluctuation when the inclined slinger 30 rotates to the highest point. The drive assembly 50 is located at the bottom of the chassis 10. The output end of the drive assembly 50 is connected to the inclined shaft 60. The inclined shaft 60 is connected to the inclined flange 70 through an angular contact ball bearing. The top end of the inclined shaft 60 is connected to the inclined slinger 30, and the inclined flange 70 is fixed to the upper end face of the chassis 10.

[0028] In other words, when material is placed into the cylindrical silo 20, the drive assembly 50 is activated, causing the drive assembly 50 to rotate the inclined shaft 60, which in turn rotates the inclined throwing disc 30. The inclined throwing disc 30 quickly throws the material to the edge. When it reaches its highest point, the material is thrown into the discharge channel 40. To prevent the material from being thrown around, an anti-slip layer is provided on the end face of the inclined throwing disc 30. As the inclined throwing disc rotates rapidly, it throws the material, which is then ejected along the discharge channel 40, achieving efficient feeding. This throwing disc feeding mechanism, through its unique structural design, not only improves the speed and efficiency of feeding but also ensures the stability and continuity of feeding. The circular motion of the inclined throwing disc 30 within the cylindrical silo 20, combined with the precise setting of the discharge channel 40, allows the material to be accurately and quickly thrown out, meeting the high requirements of automated production lines for feeding mechanisms. Simultaneously, the design of the elastic roller 401 further enhances the stability of the inclined throwing disc 30 during rotation, effectively avoiding instability during rotation and improving the reliability and service life of the entire feeding mechanism.

[0029] In this embodiment, the cylindrical silo 20 includes an outer silo body 201, an inner silo body 202, and a guide silo body 203. The outer silo body 201 is fixed to the chassis 10. The inner silo body 202 is located inside the outer silo body 201. The bottom of the inner silo body 202 is provided with a bottom plate 204. The bottom plate 204 has a mounting hole in the center. The upper end of the inclined flange 70 passes through the mounting hole. The bottom plate 204 is fixedly connected to the inclined flange 70. The bottom plate 204 has multiple exhaust ports 205. The multiple exhaust ports 205 are arranged around the mounting hole. The inclined throwing disc 30 moves in a circle around the center of the inner silo body 202. By setting the exhaust ports 205, the resonance between the inclined throwing disc 30 and the gas in the inner silo body 202 is reduced when the inclined throwing disc 30 rotates, thereby improving the stability of the inclined throwing disc 30 rotating and throwing material.

[0030] In addition, the inner diameter of the guide hopper 203 is larger than the outer diameter of the inner hopper 202, so that the bottom of the guide hopper 203 is inserted into the inner hopper 202, and the lower end face of the guide hopper 203 is in contact with the upper end face of the outer hopper 201. Multiple support connectors 206 connected to the outer hopper 201 are fixed around the outer wall of the guide hopper 203. The discharge channel 40 extends from the inside to the outside along the circumferential side wall of the guide hopper 203. This design not only enhances the stability of the guide hopper 203, making it stable during material transmission and reducing deviation or damage caused by vibration or external force, but also further improves the structural strength of the entire feeding mechanism through the tight connection between the support connectors 206 and the outer hopper 201. The extension design of the discharge channel 40 along the circumferential side wall of the guide hopper 203 ensures that the material can accurately and smoothly enter the next process along the preset path when it is thrown out, effectively avoiding the scattering or blockage of the material during the transmission process, thereby improving the overall efficiency and stability of the automated production line.

[0031] Furthermore, the bottom of the material guide hopper 203 is equipped with a top cover 207, inside which is a support frame 208. The support frame 208 has an adjustment groove and a material-pushing plate 209 connected to the adjustment groove via an adjustment rod. The top cover 207 has an inspection window, and handles are provided on both sides of the top of the top cover 207. Stacked or piled materials can be pushed aside using the material-pushing plate 209 to avoid stacking or piling. The adjustment groove allows adjustment of the height of the material-pushing plate 209 to accommodate materials of different heights, enhancing the flexibility and applicability of material feeding. The inspection window design allows staff to observe the material condition inside the material guide hopper 203 in real time, promptly identify and address potential problems, and ensure the smooth operation of the material supply process. The handles on both sides of the top of the top cover 207 facilitate opening, closing, and handling operations, improving ease of use.

[0032] like Figure 4As shown, in this embodiment, the drive assembly 50 includes a motor 501, a mounting plate 502, and a coupling 503. The mounting plate 502 includes an inclined portion 5021 and Z-shaped connecting portions 5022 located at both ends of the inclined portion 5021. The inclined portion 5021 and the two Z-shaped connecting portions 5022 are integrated. The inclined direction of the inclined portion 5021 is consistent with the inclined direction of the inclined slinger 30. The Z-shaped connecting portions 5022 are connected and fixed to the chassis 10. The motor 501 is fixed to the bottom surface of the inclined portion 5021. The inclined portion 5021 has a first clearance hole through which the output shaft of the motor 501 passes. The coupling... The coupling 503 is connected to the output shaft of the motor 501 and the inclined shaft 60 respectively; the chassis 10 has a second clearance hole corresponding to the first clearance hole, the inclined shaft 60 passes through the second clearance hole and is connected to the coupling 503, and the mounting hole and the second clearance hole coincide with the central axis of the inclined flange 70; by setting the inclined part 5021 on the mounting plate 502 connected to the motor 501, the output shaft of the motor 501 can be better aligned with the inclined shaft 60, ensuring the stability and efficiency of power transmission, and reducing vibration and energy loss caused by coaxiality deviation.

[0033] like Figure 5 As shown, in an optional embodiment, the discharge channel 40 includes a channel body 400, the channel body 400 having a guide groove 402, the bottom surface of the guide groove 402 being flush with the top surface of the inner chamber 202, and the bottom of the guide groove 402 near one end of the inner chamber 202 having an arc-shaped connecting groove 403 that matches the side wall of the inner chamber 202 and has a hollow bottom; one end of the arc-shaped connecting groove 403 extends into the inner chamber 202, one side wall is arc-shaped to guide the material into the guide groove 402, the other side wall is straight, and the outer side wall of the side wall is provided with a roller mounting seat 404 for connecting the elastic roller 401. When the material that is thrown to the top of the inclined throwing plate 30 passes through the arc-shaped connecting groove 403, the material flows smoothly into the guide groove 402.

[0034] In addition, a guide block 405 is provided on the side wall of the roller mounting base 404 along the material throwing direction. The side wall of the guide block 405 is set as an inclined surface. When the thrown material does not enter the arc-shaped connecting groove 403, due to the uncontrollability of the material throwing, some material may deviate from the expected trajectory and cannot directly enter the arc-shaped connecting groove 403. It is guided by the inclined surface to be thrown to one side to avoid the material accumulating at the port of the arc-shaped connecting groove 403.

[0035] In summary, by incorporating an inclined throwing disc 30 that rotates in a circular motion around the center of the cylindrical silo 20 within the silo 20, and then having the inclined shaft 60 driven by the drive assembly 50 rotate the inclined throwing disc 30, the material is centrifugally ejected. This design significantly improves the efficiency of material feeding. Simultaneously, the ingenious coordination between the discharge channel 40 and the inclined throwing disc 30 ensures that the material accurately enters the next process step, reducing material loss and waste during transport. The inclusion of the elastic roller 401 not only enhances the stability of the inclined throwing disc 30's rotation but also reduces noise and vibration during operation, extending the equipment's service life.

[0036] The three-layer structure of the cylindrical silo 20—namely, the outer silo 201, the inner silo 202, and the guide silo 203—makes the entire feeding mechanism more stable and reliable. The exhaust vent 205 at the bottom of the inner silo 202 effectively reduces resonance between the tilting disc 30 and the gas inside the inner silo 202 during rotation, further improving feeding stability. The inner diameter of the guide silo 203 is larger than the outer diameter of the inner silo 202, and it is tightly connected to the outer silo 201 via a support connector 206. This design not only enhances the stability of the guide silo 203 but also ensures the stability of the entire feeding mechanism during material transfer, reducing displacement or damage caused by vibration or external forces.

[0037] By setting the mounting plate 502 connected to the motor 501 with an inclined portion 5021, the drive assembly 50 enables the output shaft of the motor 501 to achieve better coaxiality alignment with the inclined shaft 60, ensuring the stability and efficiency of power transmission. This design reduces vibration and energy loss caused by coaxiality deviation, improving the overall operating efficiency of the feeding mechanism.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
