[0002] The valve core of a water valve is a core component of the water valve, and the flow and pressure of a medium can be adjusted by changing the relative position, angle or state of groove opening between the valve core and the valve seat. It is the key to the various control functions of the water valve. The valve core to be processed can be sent to the processing station one by one and in order by using the feeding device.

[0003] Most of the existing valve core feeding devices include a belt conveying table, a gripper is arranged at the front end of the belt conveying table, and the belt conveying table sends the valve core to the processing station one by one and in order. When the valve core is sent to the feeding position, the gripper transfers the valve core to the processing clamp of the processing station. Although this can also complete the feeding of the valve core, the existing valve core feeding device generally does not have a reversing function, and cannot ensure that all the valve cores located on the feeding position are arranged in the same direction, which increases the technical difficulty of subsequent processing.

[0016] In order to illustrate the technical scheme of the present application, the following will be described through specific examples.

[0018] In combination with Figures 1-2As shown, the valve core feeding reversing device comprises a machine table 1, the machine table 1 is provided with a material box 2, the material box 2 is provided with a feeding mechanism, the material box 2 is provided with a belt conveying table 3 above, the tail of the rack 4 of the belt conveying table 3 is provided with a pair of front and rear notches 5, the rack 4 is provided with a pushing cylinder 6 opposite to the front notch, the rear notch is provided with a reversing seat 7, the reversing seat 7 is provided with a through reversing groove 8, the driving shaft of the pushing cylinder 6 is provided with a push block 9, the machine table 1 is provided with a discharging rack 10, the push block 9 is arranged towards the entrance of the reversing groove 8, the top of the discharging rack 10 is arranged towards the exit of the reversing groove 8, the rack 4 is provided with a bracket 101 for installing an inductor opposite to the entrance of the reversing groove 8, the bracket 101 is provided with an inductor arranged downwards (not shown in the figure). The machine table 1 is provided with a reversing mechanism for driving the reversing seat 7 to rotate, the reversing mechanism comprises a driven wheel 11 mounted on the reversing seat 7, the machine table 1 is provided with a rotating cylinder 12, the driving shaft of the rotating cylinder 12 is provided with a driving wheel 13, and the driving wheel 13 and the driven wheel 11 are sleeved with a belt.

[0019] The water valve core is the core component of the water valve, and the valve core to be processed can be sequentially sent to the processing station by using the feeding device during the processing.

[0020] Specifically: a batch of valve cores to be processed are put into the material box, then the feeding mechanism feeds a certain number of valve cores to the belt conveying table, the belt conveying table conveys the valve cores, and all the valve cores are in a flat state. When the valve core is conveyed to the reversing station, the valve core is located between the reversing seat and the push block. If the inductor senses that the valve core is in a front and rear arrangement state, the pushing cylinder drives the push block to directly push the valve core into the entrance of the reversing groove and push it out of the exit of the reversing groove, and the valve core is discharged onto the discharging rack. In this embodiment, there is a receiving seat below the discharging rack, and finally the valve core on the receiving seat is transferred to the processing station by a gripper.

[0021] If the inductor senses that the valve core is in a reverse arrangement state, the pushing cylinder drives the push block to gently push the valve core into the reversing groove, and then the push block resets. At this time, the reversing mechanism drives the reversing seat to rotate by 180 degrees, and the valve core rotates and completes the reversing action. Then the pushing cylinder drives the push block to push the valve core out of the reversing groove, and the valve core falls on the receiving seat through the discharging rack. It is worth noting that when the device feeds the valve core, all the valve cores on the receiving seat can be aligned by the reversing mechanism, and the gripper can place the valve core on the processing station as required.

[0022] In this structure, the reversing groove is a rectangular structure, and the size of the reversing groove matches the size of the valve core. In this way, when the valve core is pushed into the reversing groove, the reversing groove plays a limiting role on the valve core. This improves the stability during subsequent reversing.

[0023] When the reversing mechanism is needed to drive the reversing seat to rotate 180 degrees, the rotary cylinder drives the drive wheel to rotate 180 degrees. Under the linkage of the belt, the driven wheel drives the reversing seat to rotate 180 degrees synchronously, completing the reversing action of the valve core.

[0024] In this structure, such as Figure 2 The frame 4 has an opening, and the frame 4 is equipped with a blocking cylinder 14. The blocking cylinder 14 is on the same side as the pushing cylinder 6 and is located to the left of the pushing cylinder. The drive shaft of the blocking cylinder 14 is equipped with a stop block 15, and the stop plate is located inside the opening.

[0025] During the feeding process of the valve core, if the current valve core is transported to the reversing station, the blocking cylinder immediately drives the stop block to move to the right. The stop block blocks the valve core, preventing the subsequent valve core from moving forward and ensuring that the current valve core can accurately enter the reversing slot.

[0026] As a preferred structure, such as Figures 3-4 The bottom plate 16 of the material box 2 is inclined forward and downward, and the front end of the bottom plate 16 has a notch. The feeding mechanism includes a push plate 17 that is slidably installed in the material box 2 within the notch. The material box 2 is provided with a drive seat 18, and a linear motor 19 is provided in the drive seat 18. The drive end of the linear motor 19 is connected to the push plate 17.

[0027] A pair of push seats 20 are symmetrically arranged on the front side of the push plate 17 about the drive seat 18. The push plate is in its initial position, and the push seats have a certain number of valve cores. When the feeding mechanism is used to feed the valve cores from the material box onto the belt conveyor, the linear motor drives the push plate to move upwards, and the push seats move upwards synchronously. At that time, all the valve cores on the push seats move upwards along the inner wall of the material box until these valve cores are pushed onto the belt conveyor. Afterwards, the push plate returns to its initial position.

[0028] Because the bottom plate of the material box is tilted forward and downward, when the push plate returns to the starting position, the valve core on the bottom plate slides down onto the push seat.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
