The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] This utility model embodiment provides a feeding device for valve stem processing, such as... Figures 1-5As shown, the valve stem processing feeding device includes: a base plate 1, a housing 2 fixedly mounted on the top of the base plate 1, a rotating shaft 3 rotatably mounted on the housing 2, two circular plates 4 fixedly sleeved on the rotating shaft 3, and two placement slots 5 for placing valve stems to be processed on each of the two circular plates 4; a transmission pipe 6 fixedly mounted on the housing 2 at one end and cooperating with the placement slots, and a hopper 7 fixedly mounted on the other end of the transmission pipe 6; multiple support rods 8 fixedly mounted on the top of the base plate 1, with the same top plate 9 fixedly mounted on the top ends of the multiple support rods 8; a drive mechanism mounted on the base plate 1 for rotating the rotating shaft 3; and a feeding mechanism mounted on the top plate 9 for transporting valve stems to the processing equipment.

[0024] In this embodiment, when using the device, it needs to be fixedly placed in a suitable position on one side of the processing equipment. Then, a large number of valve stems to be processed are put into the hopper 7 at once, and then enter the transfer pipe 6 for storage from the hopper 7. The outermost valve stem is located in the placement slot. The two pairs of placement slots on the two circular plates can be called the bottom placement slot and the top placement slot. A controller for controlling the automatic operation of the device can be installed on the back of the device. The controller model can be G6F-DA2V, which is prior art, and its principle is not described. When a feeding operation is required to feed the processing equipment, it is activated. When the device is powered on, the controller will first start the drive mechanism under the set action. The drive mechanism will drive the rotating shaft 3 to rotate on the housing 2. The rotating shaft 3 will drive the two circular plates 4 to rotate half a turn, so that the placement slots 5 at the bottom of the two circular plates 4 can transmit the outermost valve stem to the top of the housing 2. Then the feeding mechanism will run, which will clamp the valve stem transmitted to the top of the housing 2 and move it to the processing area of ​​the processing equipment for placement. This can effectively replace the workers in completing the feeding work, which can greatly reduce the labor intensity of the workers, prevent fatigue during long-term work, and help improve production efficiency and safety.

[0025] In a further preferred embodiment of the present invention, the driving mechanism includes: a first servo motor 10 fixedly mounted on the top of the base plate 1, a first sprocket 11 fixedly sleeved on the output shaft of the first servo motor 10; a second sprocket 12 fixedly sleeved on the rotating shaft 3; and a chain 13 sleeved on the first sprocket 11 and the second sprocket 12.

[0026] In this embodiment, the drive mechanism is used to rotate the shaft 3. During operation, the first servo motor 10 drives the first sprocket 11 to rotate. The first sprocket 11 drives the second sprocket 12 to rotate through the chain 13. The second sprocket 12 drives the shaft 3 to rotate on the housing 2. The shaft 3 drives the two circular plates 4 to rotate half a turn, so that the placement slots 5 at the bottom of the two circular plates 4 can transmit the second valve stem to the top of the housing 2, and the placement slots 5 at the top of the two circular plates 4 will enter the position of the bottom placement slot.

[0027] In a further preferred embodiment of this utility model, the feeding mechanism includes: an electric slide rail 14 fixedly installed at the bottom of the top plate 9; an electric telescopic rod 15 fixedly installed on the sliding block of the electric slide rail 14; a horizontal plate 16 fixedly installed on the output rod of the electric telescopic rod 15; side plates extending downward from both ends of the horizontal plate 16; and sliding grooves provided on the side plates; a bidirectional screw 17 rotatably installed on the sliding grooves; both ends of the bidirectional screw 17 extending beyond the side plates; a second servo motor 18 disposed on one side of the horizontal plate 16; the output shaft of the second servo motor 18 fixedly connected to one end of the bidirectional screw 17; two sliders 19 threadedly installed on the two threaded sections of the bidirectional screw 17; both sliders 19 slidably connected to the bottom of the horizontal plate; and two clamping blocks 20 respectively fixedly installed on the two sliders 19.

[0028] In this embodiment, the feeding mechanism is used to transport the valve stem to the processing equipment. During operation, the electric telescopic rod 15 drives the horizontal plate 16 and the two clamping blocks 20 below it to descend. When the two clamping blocks 20 reach the appropriate position, the electric telescopic rod 15 stops working. Then, the second servo motor 18 drives the bidirectional screw 17 to rotate. The bidirectional screw 17 drives the two sliders 19 to move closer to each other. The two sliders 19 drive the two clamping blocks 20 to move closer to each other until the two clamping blocks 20 clamp the valve stem above the housing 2. After clamping, the electric telescopic rod 15 drives the horizontal plate 16 and the two clamping blocks 20 below it to rise, thus clamping the valve stem. The valve stem can detach from the placement slot 5 and rise to a suitable position. The electric slide rail 14 will drive the electric telescopic rod 15, the horizontal plate 16 and the two clamping blocks 20 below to move horizontally. When it moves to the processing area of ​​the processing equipment, the valve stem needs to be released. When releasing, the second servo motor 18 is started to drive the bidirectional screw 17 to rotate in the opposite direction. The bidirectional screw 17 will drive the two sliders 19 to move away from each other. The two sliders 19 will drive the two clamping blocks 20 to move away from each other, thereby realizing the release of the valve stem and completing the feeding work. Then, the feeding mechanism needs to return to its original state in order to carry out the next feeding work.

[0029] In a further preferred embodiment of the present invention, an arc-shaped groove is provided on the side of each of the two clamping blocks 20 that are close to each other, and an arc-shaped pad 21 for anti-slip is fixedly installed on each of the two arc-shaped grooves.

[0030] In this embodiment, the combined use of two arc-shaped grooves and two arc-shaped pads 21 can effectively improve the clamping effect of the two clamping blocks 20 on the valve stem, so as to prevent slippage and displacement.

[0031] In a further preferred embodiment of the present invention, the base plate 1 is provided with a plurality of mounting holes, all of which are used for mounting bolts.

[0032] In this embodiment, the use of multiple mounting holes allows personnel to easily fix the device to the ground on one side of the processing equipment using bolts.

[0033] In a further preferred embodiment of the present invention, a support base is fixedly installed on the top of the base plate 1, and the top of the support base is fixedly connected to the transmission pipe 6.

[0034] In this embodiment, the use of a support base can provide good support for the transmission pipe 6, making the transmission pipe 6 stable during use.

[0035] In a further preferred embodiment of the present invention, the second servo motor 18 is fixedly mounted on one side of the horizontal plate 16 by a trapezoidal block, and the bidirectional screw 17 is made of stainless steel.

[0036] In this embodiment, the bidirectional screw 17, made of stainless steel, has good corrosion resistance and durability, is not easily damaged during long-term use, and has a good service life.

[0037] In summary, compared with related technologies, this solution, through the combined use of the transmission pipe 6 and the hopper 7, can store a large number of valve stems to be processed. The drive mechanism allows the rotating shaft 3 to rotate the two circular plates 4 half a turn, enabling the placement slots 5 at the bottom of the two circular plates 4 to transfer one of the valve stems from the transmission pipe 6 to the top of the housing 2. Meanwhile, the placement slots 5 at the top of the two circular plates 4 enter the interior of the housing 2. The feeding mechanism replaces manual labor in clamping the valve stems transferred to the top of the housing 2 and moving them to the processing area of ​​the processing equipment for placement, thus completing the feeding process. This significantly reduces the labor intensity of workers, improves production efficiency and safety, and effectively solves the problem of worker fatigue caused by the need for manual placement of valve stems onto the processing equipment during prolonged repetitive operations.

[0038] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
