Description

Technical Field

[0001] This invention relates to the field of vibratory feeding equipment technology, and in particular to a vibratory feeder with adjustable feeding direction. Background Technology

[0002] Currently, hopper-type vibratory feeding and separating machines for raw metals mainly rely on hopper storage and a vibrating structure to achieve the conveying and screening of metal workpieces. The overall feeding flow direction is fixed and singular, and it can only achieve single-direction discharge. It cannot flexibly switch the feeding and discharge direction according to the production line layout and workstation arrangement. Existing equipment has problems such as poor discharge diversion flexibility, weak adaptability to multi-workstation production lines, and inconvenience in adjusting the workpiece conveying and arrangement. At the same time, the traditional vibratory feeding structure has an unreasonable component arrangement, low workpiece discharge and separation alignment accuracy, and metal workpieces are prone to deviation and accumulation during the conveying process, making it difficult to meet the actual use requirements of multi-directional diversion feeding in automated production lines.

[0003] To address the aforementioned issues, a vibratory feeder with adjustable feeding direction is proposed. Summary of the Invention

It realizes vibration conveying, automatic separation and multi-directional adjustable discharge of metal workpieces, and improves the versatility of equipment and adaptability to production lines.

[0021] The present invention will be further described in detail below with reference to specific embodiments, so as to better understand the scope of protection of the present invention. However, the scope of protection of the present invention is not limited to the following embodiments.

[0022] Example 1: A vibratory feeding and separating machine for metal workpieces with adjustable feeding direction, such as... Figure 1-5 As shown, the system includes a main frame 1, an adjustable discharge diverter 2, a hopper storage bin 3, a conveying assembly 4, and a feeding and separating assembly 5. The assembly relationship and specific structure of each component are as follows: The main frame 1 is welded from Q235 steel plate and has an overall frame structure. Anti-slip feet are welded to the bottom to ensure the overall stability of the equipment and prevent displacement or shaking during vibration. The hopper storage bin 3 is fixedly installed on one side by bolts. The hopper storage bin 3 is made of stainless steel and is funnel-shaped. The bottom discharge port is set directly opposite the input end of the conveyor belt 403.

[0023] The upper part of the main frame 1 is sequentially equipped with a conveying assembly 4 and a feeding and separating assembly 5. The conveying assembly 4 consists of a main drive shaft 401, a secondary drive shaft 402, a conveyor belt 403, and a drive motor 404. The main drive shaft 401 and the secondary drive shaft 402 are rotatably mounted inside the main frame 1 through bearings and are arranged in parallel. The conveyor belt 403 is sleeved on the outside of the main drive shaft 401 and the secondary drive shaft 402. The conveyor belt 403 is made of wear-resistant rubber material and has anti-slip texture on the surface to increase the friction with the metal workpiece and prevent the workpiece from slipping during the conveying process. The drive motor 404 is fixed to the side wall of the main frame 1 by bolts. The output shaft of the drive motor 404 is connected to the main drive shaft 401 through a coupling to provide power for the operation of the conveyor belt 403. The drive motor 404 is a stepper motor, and the speed can be adjusted according to actual needs, thereby adjusting the conveying speed.

[0024] The feeding and separating assembly 5 is installed on the discharge end side of the conveying assembly 4, and includes a lower mounting plate 501, an upper mounting plate 502, a discharge end guide plate 503, a feeding trough frame 504, a fixed end seat 505, a guide shaft 506, a vibration buffer spring 507, a discharge trough 508, a workpiece separating grid 509, and a separating discharge channel 510. The lower mounting plate 501 is fixed to the upper end of the main frame 1 by bolts. The upper mounting plate 502 is installed obliquely above the lower mounting plate 501, with an inclination angle of 15°-30°. 1. A fixed end seat 505 is installed at the top. A guide shaft 506 is installed between the fixed end seat 505 and the lower connecting part of the upper mounting plate 502. A vibration buffer spring 507 is sleeved on the outside of the guide shaft 506. The two ends of the vibration buffer spring 507 are connected to the fixed end seat 505 and the lower connecting part of the upper mounting plate 502, respectively. A protective sleeve made of flexible wear-resistant material is sleeved on the outside of the vibration buffer spring 507 to protect the vibration buffer spring 507 and prevent the debris generated during the metal workpiece conveying process from entering the spring gap, causing the spring to jam or be damaged.

[0025] The upper mounting plate 502 serves as the support plate for the discharge end guide plate 503. The discharge end guide plate 503 is fixed to the upper end of the upper mounting plate 502 by bolts, which facilitates the smooth sliding of the metal workpiece by its own weight and vibration. The feeding trough frame 504 is installed obliquely above the discharge end guide plate 503 by bolts, and its inclination angle is the same as that of the discharge end guide plate 503. The inner side of the feeding trough frame 504 is provided with a side baffle integrally formed with itself to limit the conveying range of the metal workpiece and prevent the workpiece from falling from both sides of the feeding trough frame 504.

[0026] The surface of the discharge end guide plate 503 is provided with 8 sets of discharge troughs 508. The workpiece separation grid 509 is made of wear-resistant stainless steel and is detachably connected to the feeding trough frame 504. The bottom end of the discharge trough 508 is connected to the separation discharge channel 510. The separation discharge channel 510 is made of seamless steel pipe and has a smooth wear-resistant polytetrafluoroethylene coating on the inner wall to reduce the resistance of workpiece conveying. The discharge end of the separation discharge channel 510 is precisely connected to the feed channel 202 of the adjustable discharge diversion 2 to ensure that the metal workpiece flows smoothly into the diversion structure and avoids workpiece jamming.

[0027] Adjustable discharge diverter 2 is fixedly installed at the discharge end of the main frame 1, and includes a base frame 207, a receiving plate 201, a feeding channel 202, a side discharge channel 203, a chute 204, a reversing baffle 205, a connecting plate 206, and a drive electric push rod 208. The base frame 207 is fixed to the end of the main frame 1 by bolts. The receiving plate 201 is inclinedly fixed on the base frame 207. The inclination angle of the receiving plate 201 is consistent with that of the discharge end guide plate 503 to ensure smooth transition of the workpiece. A feeding channel 202 is opened on the inner side of the receiving plate 201, and a side discharge channel 203 is connected to the side of the receiving plate 201. The feeding channel 202 and the side discharge channel 203 are arranged at 90° and correspond to different discharge stations. A sliding groove 204 is opened on the surface of the receiving plate 201. A reversing baffle 205 is slidably assembled inside the sliding groove 204. A wear-resistant slider is provided at the connection between the reversing baffle 205 and the sliding groove 204 to reduce wear during sliding and ensure smooth reversing action without jamming.

[0028] The drive electric actuator 208 is fixed to the outside of the base frame 207 by the mounting base. The drive electric actuator 208 is a linear telescopic drive structure. Its output end is fixedly connected to the reversing baffle 205 through the connecting plate 206. The drive electric actuator 208 is electrically connected to a PLC controller, which can realize automatic electric reversing. The operator can remotely control the extension and retraction of the drive electric actuator 208 through the controller, thereby switching the blocking position of the reversing baffle 205, realizing the switching between the feed channel 202 and the side discharge channel 203, and completing the adjustment of the feeding direction.

[0029] The working process of this embodiment is as follows: Material preparation: Place the metal workpieces to be conveyed and separated, such as small bolts and stamped parts, into the hopper storage bin 3. Adjust and install the corresponding workpiece separation grid 509 according to the workpiece specifications. Adjust the discharge valve at the bottom of the hopper storage bin 3 and set an appropriate discharge speed. Conveying operation: Start the drive motor 404, drive the main drive shaft 401 to rotate, drive the main drive shaft 401 to rotate, and drive the conveyor belt 403 to rotate. The metal workpieces in the hopper storage bin 3 fall from the bottom discharge port onto the conveyor belt 403, and are smoothly conveyed by the conveyor belt 403 to the feeding trough frame 504 of the feeding and separating component 5. Vibration separation: The vibration buffer spring 507 generates directional vibration, which drives the upper mounting plate 502, the discharge end guide plate 503 and the feeding trough frame 504 to vibrate synchronously. The metal workpiece moves with the vibration in the feeding trough frame 504. When it passes through the workpiece separation grid 509, the workpiece with incorrect posture or overlapping is blocked by the grid, and the qualified workpiece falls into the separation discharge channel 510 through the discharge trough 508 corresponding to the grid. Adjustable discharge: Qualified workpieces are conveyed through the separation feeding channel 510 to the feeding channel 202 of the adjustable discharge diversion 2. According to the production station requirements, the staff controls the extension and retraction of the drive electric push rod 208 through the PLC controller. The drive electric push rod 208 drives the reversing baffle 205 to slide in the slide groove 204 through the connecting plate 206. When the reversing baffle 205 blocks the side discharge channel 203, the workpiece is discharged straight from the feeding channel 202. When the reversing baffle 205 blocks the feeding channel 202, the workpiece is discharged laterally from the side discharge channel 203, thus completing the flexible switching of the feeding direction. Shutdown maintenance: After the operation is completed, turn off the drive motor 404 and the vibration system, clean the residual workpieces and debris in the feeding trough frame 504, workpiece separation grid 509 and separation discharge channel 510, check the wear of components such as vibration buffer spring 507 and reversing baffle 205, and maintain or replace them in time.

[0030] Example 2: The difference between this example and Example 1 is that the grid gap of the workpiece separation grid 509 is a fixed specification, which is suitable for metal workpieces of a single specification and does not require adjustment. The drive electric push rod 208 adopts a manual control mode, and its extension and retraction are controlled by a manual crank. It is suitable for small manual production lines. The rest of the structure and working process are the same as in Example 1.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
