[0031] Embodiment 3 Based on embodiment 2, the embodiment discloses a water spraying kettle nozzle assembly assembling device, which comprises a feeding and discharging mechanism; As shown in Figure 2As shown, the feeding mechanism includes a first vibrating feeder 25 and a second vibrating feeder 26, and the discharging mechanism is a discharging hopper 27: The first vibrating feeder 25 is fixed on the base 1 and located at the top side of the transfer disc 23, with its discharge port aligned with the second material taking groove 24 of the transfer disc 23, for orderly delivering the valve core to the transfer disc 23; The transfer disc 23 is disc-shaped, with a plurality of second material taking grooves 24 evenly arranged on the outer side wall in the circumferential direction, and the shape of the second material taking groove 24 is adapted to the valve core, for carrying and transferring the valve core; The second vibrating feeder 26 is fixed on the base 1 and located at one side of the pressure plate 7, with its discharge port aligned with the first material taking groove 8 of the pressure plate 7, for orderly delivering the nozzle shell to the first material taking groove 8; The discharging hopper 27 is made of stainless steel and is fixed on one side of the limiting ring 2 through a support, with its top end inclined upward at an angle of 30-45°, and the top end inlet is aligned with the discharging position of the pressure plate 7, and the bottom end extends to the outside of the device, for receiving and delivering the assembled nozzle product.

[0032] The specific working principle is as follows. The working process of the water spraying kettle nozzle assembly device of the embodiment includes four stages of feeding, positioning, assembling, and discharging, which are automatically synchronized throughout the process. Start the motor 22, the motor 22 drives the second gear 21 to rotate through the shaft coupling, the second gear 21 engages to drive the first gear 20 and the inner lining cylinder 3 to rotate, and at the same time, the motor 22 drives the transfer disc 23 to rotate synchronously through the belt and pulley, the rotation angular velocity of the inner lining cylinder 3 is consistent with that of the transfer disc 23, and the assembly rhythm is matched.

[0033] Valve core feeding: start the first vibrating feeder 25, and the valve core is orderly output along the discharge channel of the first vibrating feeder 25 under the vibration action, and accurately falls into the second material taking groove 24 of the transfer disc 23, and is transferred to the assembly component direction with the rotation of the transfer disc 23; Shell feeding: start the second vibrating feeder 26, and the nozzle shell is orderly output along the discharge channel of the second vibrating feeder 26 under the vibration action, and falls into the first material taking groove 8 of the pressure plate 7, and is stably clamped in the first material taking groove 8 under the limiting action of the stop block 18 and the dredging arc plate 19, and is transferred to the assembly station with the rotation of the pressure plate 7 and the inner lining cylinder 3.

[0034] When the shell is transported to the assembly station with the first material slot 8, the inner lining cylinder 3 drives the first ejector pin 6 to rotate synchronously, one end of the first ejector pin 6 abuts against the outer wall of the shell, realizing the radial positioning of the shell; at the same time, the rotation of the inner lining cylinder 3 drives the connecting pin 16 to move circumferentially around the center column 5, the bottom end of the connecting pin 16 intermittently contacts the protrusions 15 on the center column 5 and the inner lining cylinder 3, generating a longitudinal amplitude, which is transmitted to the shell and the subsequently assembled valve core through the first ejector pin 6, effectively reducing the friction between the valve core and the inner wall of the shell, and providing convenience for subsequent compression assembly.

[0035] When the transfer disc 23 transfers the valve core to directly below the assembly station, the valve core is just above the material supporting rod 10; at this time, the connecting ring 4 rotates with the inner lining cylinder 3, driving the second ejector pin 9 and the pulley rod 12 to rotate synchronously, the pulley at the bottom of the pulley rod 12 slides along the inclined groove 13 of the limiting ring 2, the inclined structure of the inclined groove 13 makes the pulley rod 12 gradually displace upward, thereby driving the second ejector pin 9 and the material supporting rod 10 to move upward, and the material supporting rod 10 lifts the valve core upward and precisely embeds it into the lower shower head shell.

[0036] With the continuous rotation of the connecting ring 4, the pulley enters the wave slope 14 area on the inclined groove 13, and under the action of the wave crest and trough of the wave slope 14, the pulley rod 12 drives the second ejector pin 9 and the material supporting rod 10 to be in an up-and-down state, exerting intermittent upward pressure on the valve core, so that the assembly of the valve core and the shell is more compact, avoiding the phenomenon of looseness.

[0037] After assembly is completed, the inner lining cylinder 3 continues to drive the pressure plate 7 to rotate, and when the first material slot 8 carrying the finished product shower head is transported to the inlet of the lower hopper 27, the finished product shower head is separated from the first material slot 8 under the action of the centrifugal force of the device and the gravity of the finished product itself, and falls into the lower hopper 27, slides out of the device along the inclined channel of the lower hopper 27, and completes the entire assembly process.

[0038] In the above process, the feeding, positioning, assembly and discharging are synchronously and circularly carried out without manual intervention, which greatly improves the assembly efficiency of the shower head assembly of the shower pot, avoids the problems of missing assembly and loose assembly caused by manual assembly, and is suitable for large-scale batch production.

[0039] In the embodiment, the number of each component can be adjusted according to actual production needs, for example, the number of the first ejector pin 6, the first material slot 8 and the second material slot 24 can be set to 4-8, which does not affect the technical effects of the present application.

[0040] The above is only a preferred embodiment of the present application and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
