Description

Technical Field

[0001] The utility model relates to a material filling device, in particular to an automatic material filling device for a vibration feeder. Background Art

[0002] At present, the thread rolling process of fastener bolt production on the market adopts a vibration plate feeder. The vibration plate feeder can decompose the bolts and feed them to the thread rolling machine one by one. However, the vibration plate is small, and the semi-finished bolts added to the vibration plate each time are limited. Often, the operator needs to personally add the semi-finished bolts to the vibration plate in a very short time. However, during the production process, an operator needs to operate multiple devices at the same time, so that some machines cannot add the semi-finished bolts to the vibration plate in time, which makes the machine production efficiency low. At the same time, the operator spends most of the time adding semi-finished bolts to the vibration plate, resulting in fewer machines that the operator can operate and a higher workload and labor intensity for the operator. This device is designed to solve the problem of automatically adding semi-finished bolts to the vibration plate. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] When the vibrating plate feeder of the automatic feeding device for the vibrating feeder of the utility model is working, the semi-finished products in the vibrating plate rotate along the material channel in the vibrating plate, and the lower end of the induction rod is moved by the semi-finished products in the vibrating plate, so that the vibrating rod tilts away from the sensor;

The solenoid valve controls the cylinder to push out the piston rod, and the movable baffle is closed. The semi-finished products fall from the second discharge port and the feeding stops.

[0015] When the semi-finished products in the vibration plate loader are consumed again, the sensor senses the sensing rod again, and the sensor sends a signal to the solenoid valve. The solenoid valve controls the cylinder to retract the piston rod so that the movable baffle opens to add semi-finished products to the vibration plate loader. This reciprocating process realizes automatic addition of semi-finished products to the vibration plate loader.

[0016] In the thread rolling machine described in the utility model, the operator only needs to pour the semi-finished product into the hopper to realize the automatic loading of the semi-finished product, and there is no need for the operator to add the semi-finished product to the vibration plate at a fixed time.

A connecting hole 17 is provided above 20, a movable baffle 10 is provided at the second discharge port 20, a mounting hole 18 is provided on the movable baffle 10, and the mounting hole 18 is connected to the connecting hole 17 through a rotating shaft 21, so that the movable baffle 10 can rotate at the second discharge port 20, rotating around the axis of the rotating shaft 21, a bracket 2 is provided on the vibration disk, the bracket 2 is used to fix the cylinder 5 and the solenoid valve 3, a driving mechanism is provided on the bracket 2, the output end of the driving mechanism is movably connected to the movable baffle 10, and the sensing mechanism is arranged on one side of the driving mechanism.

[0024] The driving mechanism includes a solenoid valve 3 and a cylinder 5. The cylinder 5 is connected to the solenoid valve 3. The solenoid valve 3 and the cylinder 5 are both arranged on the bracket 2. The solenoid valve 3 is arranged above the cylinder 5. The cylinder 5 is provided with a cylinder 5 piston rod. The end of the cylinder 5 piston rod on the cylinder 5 is provided with a connecting seat 13. The movable baffle 10 is provided with a mounting seat 14. The connecting seat 13 is rotatably connected with the mounting seat 14. The solenoid valve 3 is used to receive the signal released by the sensor 6 and then control the cylinder 5 to push out or retract the piston rod. The cylinder 5 is connected to the air pump. The cylinder 5 is used to drive the piston rod to push out and retract to control the closing and opening of the movable door panel.

[0025] As a further improvement of the above-mentioned method, the air cylinder 5 can also be replaced by a hydraulic cylinder. When the hydraulic cylinder is used, the hydraulic cylinder is connected to a hydraulic pump.

[0026] As a further improvement of the above-mentioned method, a throttle valve 4 is provided on one side of the cylinder 5. The throttle valve 4 is arranged on the air pipe of the cylinder 5. The throttle valve 4 is used to adjust the flow in the air pipe of the cylinder 5 and control the speed of pushing out and retracting the piston rod of the cylinder 5.

[0027] Further, the sensing mechanism includes a sensor 6, a sensing rod 7 and a sensor bracket 9. The sensor bracket 9 is provided below the bracket 2, and the sensor 6 is provided on the sensor bracket 9. The sensor 6 is used to send a signal to the solenoid valve 3.

[0028] As a further improvement of the above-mentioned method, a mounting column 15 is provided on the lower outer wall of the hopper 1, a mounting column 2 16 is provided below the movable baffle 10, and the mounting column 15 and the mounting column 2 16 are connected by the movable baffle 11.

[0029] The utility model further provides a thread rolling machine. The thread rolling machine is provided with a vibration feeder. The vibration feeder is provided with an automatic feeding device for the vibration feeder.

[0031] When the semi-finished products in the vibration plate of the vibration plate loader 8 are consumed or there are few semi-finished products, causing the sensor rod 7 to sag naturally, the sensor 6 senses the sensor rod 7, and the sensor 6 sends a signal to the solenoid valve 3. The solenoid valve 3 controls the cylinder 5 to contract the piston rod of the cylinder 5. When the piston rod of the cylinder 5 contracts, the movable baffle 10 is controlled to open, and the semi-finished products in the hopper 1 are automatically added to the vibration plate of the vibration plate loader 8. After the semi-finished products are added to the vibration plate of the vibration plate loader 8, the semi-finished products move and contact with the sensor rod 7 while moving with the end of the sensor rod 7. The vibration rod tilts away from the sensor 6, and the sensor 6 sends no signal to the solenoid valve 3. The solenoid valve 3 controls the cylinder 5 to push out the piston rod, and the movable baffle 10 is closed, so that the semi-finished products fall from the discharge port 20, and the loading stops.

[0032] When the semi-finished products in the vibration plate of the vibration plate loader 8 are consumed again, the sensor 6 senses the sensing rod 7 again, and the sensor 6 sends a signal to the solenoid valve 3. The solenoid valve 3 controls the cylinder 5 to retract the piston rod so that the movable baffle 10 opens to add the semi-finished products to the vibration plate of the vibration plate loader 8. This reciprocating process realizes the automatic addition of semi-finished products to the vibration plate of the vibration plate loader 8.

[0033] In the thread rolling machine described in the utility model, the operator only needs to pour the semi-finished product into the hopper 1 to realize the automatic loading of the semi-finished product, and there is no need for the operator to add the semi-finished product to the vibration plate at a fixed time. The operator can operate more thread rolling machine stations at the same time, and the labor intensity of the operator can be greatly reduced. At the same time, the phenomenon of empty thread rolling of the thread rolling machine can be reduced, and the production efficiency of the thread rolling machine can be improved. Whether there is a product in the vibration plate of the vibration plate feeder 8 is determined by whether the induction rod 7 is tilted, and then a signal is sent to the solenoid valve 3 through the sensor 6. The solenoid valve 3 controls the cylinder 5 to switch the movable baffle 10 to realize automatic loading.
