At present, there is a device for automatically screwing the lower cover and the upper cover in the prior art, such as the patent No. CN2019108548267 discloses a nozzle cap screwing device, which sends the nozzle to the workbench in the nozzle feeding interval, sends the upper cover to the lower cover in the cap screwing feeding interval, and screws the upper cover on the lower cover in the cap screwing interval. In the process of conveying the upper cover to the lower cover, the upper cover is difficult to be placed on the lower cover, which will affect the screwing of the upper cover in the cap screwing interval and the assembly quality. SUMMARY

[0003] The utility model aims at overcoming the defects in the prior art and providing a cap screwing device capable of reliably conveying nozzle upper cover.

[0004] To achieve the above object, the utility model discloses a cap screwing device capable of reliably conveying nozzle upper cover, which comprises a workbench, a lower cover conveying mechanism arranged on the workbench, an upper cover feeding mechanism and a cap screwing mechanism. The lower cover conveying mechanism is used to drive the nozzle lower cover to move. The cap screwing mechanism is used to screw the nozzle upper cover on the nozzle lower cover.

[0005] The upper cover feeding mechanism comprises a feeding seat, a pressing piece and a driving device.

[0006] The feeding seat is located above the lower cover conveying mechanism. The feeding seat is provided with a feeding channel. One end of the feeding channel is provided with a discharging hole. The discharging hole penetrates to the bottom surface of the feeding seat.

[0007] The inner side wall of the discharging hole is provided with a limiting part. The limiting part is used for limiting cooperation with the outer side wall of the upper cover.

[0008] The bottom of the pressing piece is a pressing part. The pressing part is arranged opposite to the discharging hole and is used for abutting and pressing cooperation with the top surface of the upper cover.

[0009] The driving device is connected with the pressing piece and is used for driving the pressing piece to move downward to push the upper cover out of the discharging hole to the lower cover conveying mechanism and driving the pressing piece to move upward to above the feeding channel.

[0010] Preferably, the bottom surface of the feeding seat is provided with an annular groove. The annular groove is sleeved outside the discharging hole. The annular groove is provided with an opening communicated to the discharging hole.

[0011] A limiting ring is provided in the annular groove. The limiting ring is fitted inside the annular groove, and part of the limiting ring is located in the discharge hole through the opening to form the limiting part.

[0012] Preferably, the limiting ring is an elastic ring.

[0013] Preferably, the limiting ring is tightly fitted inside the annular groove.

[0014] Preferably, the bottom of the feeding seat is provided with an annular end cap, which is located at the opening of the annular groove.

[0015] Preferably, there is one feeding channel.

[0016] Preferably, there are multiple feeding channels, each feeding channel has a discharge hole at one end and an inlet at the other end that are interconnected, the width of the inlet being greater than the width of the bottle cap.

[0017] Preferably, the feeding seat is provided with a top cover that covers the feeding channel.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] In the capping device of this utility model, the feeding seat is located above the lower cover conveying mechanism. The discharge hole on the feeding seat is provided with a limiting part, which is matched with the outer side wall of the upper cover. Thus, when the upper cover is pushed to a position opposite to the discharge hole, the upper cover falls off and is stuck in the discharge hole due to the limiting part. Then, the driving device drives the pressing member to move downward to push the upper cover out of the discharge hole, so that the upper cover covers the lower cover located on the lower cover conveying mechanism. Subsequently, the lower cover conveying mechanism drives the lower cover covered with the upper cover to the capping station, and the capping mechanism tightens the upper cover onto the lower cover.

[0020] By setting a limiting part in the discharge hole, the upper cover is first locked in the discharge hole, reducing the distance between the upper and lower covers. At the same time, under the action of the pressing part, the upper cover can be stably placed on the lower cover, improving the capping quality and reducing the impact on the assembly quality caused by the upper cover not being able to be stably placed on the lower cover.

[0021] The pressing component presses the upper cover to create a discharge hole on the lower cover. At this time, the upper cover is pre-fixed on the lower cover, making it less likely to fall off during transportation. The structure is stable and significantly reduces the problem of the upper cover falling off and separating. Attached Figure Description

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] A reliable capping device for conveying the nozzle cap, see [link to documentation]. Figure 1 The device includes a workbench 100, a lower cover conveying mechanism 200, an upper cover feeding mechanism 300, a capping mechanism 400, and a feeding mechanism, all mounted on the workbench 100. The lower cover conveying mechanism 200 is used to drive the lower cover of the suction nozzle to move. The capping mechanism 400 is used to tighten the upper cover of the suction nozzle onto the lower cover of the suction nozzle. The feeding mechanism is used to remove the tightened suction nozzle from the upper cover feeding mechanism 300. The lower cover conveying mechanism 200, the capping mechanism 400, and the feeding mechanism described above can adopt the structure shown in the prior art 2019108548267, which will not be described in detail here.

[0032] In this embodiment, see Figures 2-4The upper cover feeding mechanism 300 includes a feeding seat 310, a pressing member 330, and a driving device 340. The feeding seat 310 is located above the lower cover conveying mechanism 200. The feeding seat 310 has a feeding channel 311, one end of which has a discharge hole 312 extending to the bottom surface of the feeding seat 310. A limiting part 313 is provided on the inner wall of the discharge hole 312, which is used to limit and cooperate with the outer wall of the upper cover. The bottom of the pressing member 330 is a pressing part 331, which is opposite to the discharge hole 312 and is used to press against the top surface of the upper cover. The driving device 340 is connected to the pressing member 330 and is used to drive the pressing member 330 downward to push the upper cover out of the discharge hole 312 onto the lower cover conveying mechanism 200. It can also drive the pressing member 330 upward to move above the feeding channel 311.

[0033] In this embodiment, when the upper cover is pushed in the feeding channel 311 to a position opposite to the discharge hole 312, the upper cover falls off and is locked in the discharge hole 312 by the limiting part 313. Then, the driving device 340 drives the pressing member 330 to move downward to push the upper cover out of the discharge hole 312, so that the upper cover covers the lower cover located on the lower cover conveying mechanism 200. Subsequently, the lower cover conveying mechanism 200 moves the lower cover covered with the upper cover to the capping station, and the capping mechanism 400 tightens the upper cover onto the lower cover. By setting the limiting part 313 in the discharge hole 312, the upper cover is first locked in the discharge hole 312, reducing the distance between the upper cover and the lower cover. At the same time, under the action of the pressing member 330, the upper cover can be stably covered on the lower cover, improving the capping quality and reducing the impact on the assembly quality caused by the upper cover not being stably covered on the lower cover. The pressing component 330 presses the upper cover out through the discharge hole 312 onto the lower cover. At this time, the upper cover is pre-fixed on the lower cover, making it less likely to fall off during transportation. The structure is stable, significantly reducing the problem of the upper cover falling off and separating.

[0034] In this embodiment, there are two feeding channels 311, but it can also be set to one or more. Setting multiple feeding channels 311 can improve feeding efficiency and production efficiency. Each feeding channel 311 has a discharge hole 312 at one end, and the width of each feeding channel 311 is slightly larger than the width of the top cover. In this way, the top covers in the feeding channel 311 can only move to the position of the discharge hole 312 one by one in sequence. The top covers are fed in sequence, which improves the reliability of feeding and avoids the problem that multiple top covers cannot fall out of the feeding port when the width of the feeding channel 311 is too large.

[0035] In this embodiment, there are two feeding channels 311. Correspondingly, the pressing member 330 has two pressing parts 331 to press down the two upper covers. Specifically, a bracket 341 is fixed on the feeding seat 310. The pressing member 330 is U-shaped, with the two ends of the U-shaped opening being the pressing parts 331. The two pressing parts 331 pass downward through the bracket 341 from above. A telescopic cylinder 342 is fixed on the pressing member 330, and the free end of the piston rod 343 of the cylinder is fixed to the bracket 341. When pressing down the upper cover, the piston rod 343 retracts, thereby driving the pressing member 330 to move downward, and the pressing parts 331 press down the upper cover, so that the upper cover covers the lower cover; then the piston rod 343 extends, thereby lifting the pressing member 330, and the pressing parts 331 move upward out of the feeding channel.

[0036] In order to further improve the reliability of feeding, the other ends of the two feeding channels 311 are connected to form a feeding port. The width of the feeding port is slightly larger than the width of the bottle cap, so that the caps can only flow into the feeding channel 311 one by one from the feeding port.

[0037] In this embodiment, see Figure 4 The bottom surface of the loading seat 310 is provided with an annular groove 314, which fits around the discharge hole 312. The annular groove 314 has an opening 315 that connects to the discharge hole 312. A limiting ring 320 is provided inside the annular groove 314, and part of the limiting ring 320 is located inside the discharge hole 312 through the opening 315, forming a limiting part 313. The limiting part 313 formed by the annular groove 314 and the limiting ring 320 has a simple structure and is easy to process and assemble. The structure of the annular groove 314 and the limiting ring 320 forming the limiting part 313 is set on the bottom surface of the loading seat 310 to avoid affecting the movement of the upper cover if the structure is placed inside the loading channel 311.

[0038] Among them, the limiting ring 320 is an elastic ring, and the silicone ring is tightly fitted in the annular groove 314, which improves the assembly reliability of the limiting ring 320.

[0039] To improve assembly reliability, the bottom of the loading seat 310 is provided with an annular end cover 350, which is located at the opening of the annular groove 314 to prevent the limit ring 320 from falling off.

[0040] In this embodiment, the feeding seat 310 is provided with a top cover 360 that covers the feeding channel 311. This can confine the top cover within the feeding channel 311, ensuring the stability of the top cover during transportation. In addition, it can also prevent foreign objects from entering the feeding channel 311 and affecting the transportation of the top cover.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
