Description

Technical Field

[0001] The utility model relates to the technical field of feeding mechanisms, in particular to an automatic feeding mechanism for valve stem processing. Background Art

[0002] During the production or processing of valve stems, they need to be moved to the processing site. At present, some methods pre-install the valve stems in a basket manually, and then send the basket to the processing site. During processing, workers take the valve stems in the basket one by one, which is inefficient. Some methods use a conveying mechanism to convey the valve stems to the processing site, but during conveying, it is impossible to convey the valve stems one by one, that is, after each processing is completed, another one is conveyed forward, resulting in a large number of valve stems piling up at the processing site. Moreover, they can only be conveyed to one processing point, and cannot be conveyed to two processing points at the same time, resulting in low conveying and processing efficiency. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0005] A valve stem processing automatic feeding mechanism comprises a hopper, one side of the hopper is a downwardly inclined inclined plate, a discharge port is arranged at the bottom of the hopper, a rotating shaft is rotatably connected to the hopper near the discharge port, a dividing wheel is fixed on the rotating shaft, a plurality of equidistant dividing grooves are arranged on the outer wall of the dividing wheel, a stopper is connected to the inner wall of the hopper away from the inclined plate, a side of the stopper facing the inclined plate is provided with an arc groove matching the dividing wheel, one side of the dividing wheel is rotatably arranged in the arc groove, and the other side of the dividing wheel is close to the lower end of the inclined plate; the lower end of the hopper is located at the discharge port and is connected to a bracket extending downward, a dividing channel is hinged on the bracket, and the dividing channel is located directly below the discharge port, a first driving mechanism for driving the dividing channel to rotate is arranged at the bottom of the hopper; a second driving mechanism for driving the rotating shaft to rotate is also provided on the hopper.

[0006] Preferably, the first driving mechanism includes a first motor connected to the bottom of the hopper and shafts installed on both sides of the material distribution channel. The two shafts are rotatably connected to the bracket, and one end of the first motor is transmission-connected to one of the shafts through a coupling.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

By driving the rotating shaft to rotate, the material distribution wheel is driven to rotate, and the valve stems can be discharged from the discharge port one by one in an orderly manner. When the valve stem falls on the material distribution channel, the first driving mechanism controls the material distribution channel to deflect to one side, so that the valve stem is transported from the material distribution channel to the processing point, and then the first driving mechanism controls the level of the material distribution channel.

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Example 1

[0017] See also Figure 1-2 A valve stem processing automatic feeding mechanism comprises a hopper 1, one side of the hopper 1 is a downwardly inclined inclined plate 2, a discharge port 3 is arranged at the bottom of the hopper 1, a rotating shaft is rotatably connected near the discharge port 3 in the hopper 1, a dividing wheel 4 is fixed on the rotating shaft, a plurality of equidistant dividing grooves 5 are arranged on the outer wall of the dividing wheel 4, a stopper 6 is connected to the inner wall of the hopper 1 away from the inclined plate, a side of the stopper 6 facing the inclined plate is provided with an arc groove matching the dividing wheel, one side of the dividing wheel 4 is rotatably arranged in the arc groove, thereby preventing the valve stem from falling downward from between the stopper and the dividing wheel, and the other side of the dividing wheel 4 is close to the lower end of the inclined plate 2, thereby preventing the valve stem from falling downward from between the dividing wheel and the inclined plate.

[0018] The lower end of the hopper 1 is connected to a bracket 7 extending downward at the discharge port, and a material distribution channel 8 is hinged on the bracket 7. The material distribution channel 8 is located directly below the discharge port 3. The bottom of the hopper 1 is provided with a first driving mechanism for driving the material distribution channel 8 to rotate. Specifically, the first driving mechanism includes a first motor 9 connected to the bottom of the hopper, and shafts installed on both sides of the material distribution channel. The two shafts are rotatably connected to the bracket 7, and one end of the first motor 10 is connected to one of the shafts through a coupling. Starting the first motor 10 to rotate forward or reverse can drive the shaft to rotate, thereby driving the material distribution channel 8 to rotate alternately.

[0019] The hopper 1 is also provided with a second driving mechanism for driving the rotating shaft to rotate. The second driving mechanism includes a second motor 11 installed at the lower part of the hopper, a transmission shaft connected to the second motor through a coupling, a driving wheel connected to the transmission wheel, and a driven wheel connected to the rotating shaft, and the driving wheel and the driven wheel are connected through a transmission belt. When the second motor 11 is started, the transmission shaft is driven to rotate, and the transmission shaft drives the driving wheel to rotate, thereby driving the driven wheel to rotate through the transmission belt, and finally driving the rotating shaft and the material distribution wheel to rotate.

[0020] The outer wall of the inclined plate 2 is connected with a straight vibrator 12. Through the straight vibrator 12, the inclined plate can be vibrated to make the valve stem fall onto the material distribution wheel, so as to facilitate the valve stem to enter the material distribution trough 5.

[0021] It should be noted that the hopper 1 is used to place the valve stem. When placing the valve stem, the valve stem needs to be placed vertically along the front and rear walls of the hopper 1, and the width of the inner wall of the hopper 1 needs to be slightly larger than the width of the valve stem to prevent the valve stem from rotating in the hopper, so that the valve stem can easily fall into the distribution trough 5.

[0022] The working principle of this embodiment is as follows: the valve stem 13 is pre-placed in the hopper 1, so that the valve stem is perpendicular to the front and rear walls of the hopper, the valve stem of the lower layer is stuck in the material distribution groove 5, and the valve stem can be discharged from the discharge port 3 one by one in an orderly manner by driving the rotating shaft to rotate, and the material distribution wheel 4 is driven to rotate. Due to the rotation of the material distribution wheel 4, the valve stem will also be turned over, which is conducive to the new valve stem falling into other material distribution grooves 5. When the valve stem falls on the material distribution channel 8, the material distribution channel 8 is controlled to deflect to one side by the first driving mechanism, so that the valve stem is transported from the material distribution channel to the processing point, and then the material distribution channel 8 is controlled to be horizontal by the first driving mechanism. At this time, another valve stem falls on the material distribution channel 8 again, and the material distribution channel 8 is controlled to deflect to the other side, and the valve stem is transported from the material distribution channel to another processing point. Therefore, the valve stem can be transported to two processing points at the same time, thereby improving the transportation and processing efficiency.

[0023] Example 2

[0024] The difference between this embodiment and the embodiment 1 is that a metering sensor 13 is installed on the bracket 7 toward the discharge port. The metering sensor 13 can record the number of valve stems sent out, which is conducive to statistics.

In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.
