Description

Technical Field

[0001] The utility model belongs to the technical field of bottle cap production, in particular to a correction and positioning mechanism for a combined bottle cap. Background Art

[0002] Liquor is an indispensable drink on the table when people gather together. The bottle cap is an important component used to seal the bottle. It determines the packaging effect of the wine and is a key structure to ensure the long-term quality of the wine. It requires excellent sealing to achieve the effects of anti-leakage and anti-permeation. Figure 1 As shown, the bottle cap of the wine bottle is usually a combined bottle cap (1) consisting of an inner cap (103), an outer cap (105) and a top cap (101), wherein the inner cap (103) is covered on the top of the outer cap (105), and the top cap (101) is covered on the outside of the inner cap (103), and the overall structure enhances the sealing performance of the bottle cap to the mouth of the wine bottle.

[0003] Typically, a plurality of spaced protective teeth (104) are provided on the top edge of the outer cover (105), and a notch (102) is provided at a corresponding position on the top cover (101) to surround the protective teeth (104). When opening the wine bottle to pour wine, the top cover (101) needs to be twisted to remove it from the outer cover (105). During the twisting process of the top cover (101), the edge of the notch (102) damages the protective teeth (104), and then the top cover (101) can be removed from the outer cover (105). Therefore, the protective teeth (104) play an important role in preventing others from attempting to open the wine bottle and cheat before a meal.

[0004] In the assembly process of the bottle cap, it is particularly important to accurately position the protective teeth (104) and the notch (102). Otherwise, the top cover (101) cannot be covered on the top cover (101), or the protective teeth (104) are misaligned with the notch (102) during the covering process, resulting in damage to the protective teeth (104), causing material waste. Currently, the fixing teeth of the bottle cap are mostly manually fixed next to the machine, which has low processing efficiency and high labor intensity for workers. Therefore, it is very important to develop a bottle correction and positioning mechanism. Utility Model Content

[0005] The utility model aims to provide a correction and positioning mechanism for a combined bottle cap, so as to solve the problems of low efficiency and high work intensity of manual tooth setting in the prior art.

[0006] The present invention provides a set of correction and positioning mechanism for combined bottle caps, comprising a workbench and a conveying platform located on the workbench, a toggle assembly, a correction assembly, and a positioning assembly located next to the conveying platform and arranged in sequence according to the processing order; the conveying platform is provided with a support column for placing the outer cap, and the outer cap is rotatably mounted on the support column;

[0007] The toggle assembly is used to toggle the guard teeth; the correction assembly includes a mounting seat, a fixed tooth plate and a rotary cover assembly for driving the outer cover to rotate, the rotary cover assembly is connected to the workbench by lifting, one end of the fixed tooth plate is used to limit the guard teeth; the other end of the fixed tooth plate is connected to a detection device for detecting the position state of the fixed tooth plate, the fixed tooth plate is rotatably connected to one end of the mounting seat, the mounting seat is provided with a reset assembly for driving the fixed tooth plate to return to the initial state, and the mounting seat is connected to a first movable assembly that drives it to move toward or away from the outer cover;

[0008] The positioning assembly includes a positioning base, one end of which is provided with two mirror-image clamping arms, the two clamping arms are connected to a pneumatic assembly that drives them closer to or away from each other, and the positioning base is connected to a second movable assembly that drives it to move toward or away from the outer cover.

[0009] The working principle of this solution is: the outer cover can rotate on the support column, passing through the toggle assembly, the correction assembly and the positioning assembly in sequence, and lightly contacts the toggle assembly when passing through the toggle assembly. Under the slight toggle action of the toggle assembly, the outer cover rotates so that the protective teeth will never face the direction of the toggle assembly or the correction assembly, in preparation for the correction link, avoiding positive alignment between the protective teeth and the fixed tooth plate during correction.

[0010] The outer cover continues to move to the correction assembly and pauses. The mounting seat approaches the outer cover, and the fixed tooth plate extends to any position on the outer cover in the same circumferential direction as the protective teeth. Under the action of the previous link, the protective teeth and the fixed tooth plate are misaligned. The screw cap assembly descends and rotates the outer cover until the protective teeth and the fixed tooth plate are in contact. Under the action of the protective teeth, the fixed tooth plate rotates slightly. After the detection device detects that the position of the fixed tooth plate after rotation is consistent with the preset position, the screw cap assembly stops rotating the outer cover and rises. The protective teeth are now facing the correction assembly, preparing for the next link. After the outer cover is removed, the fixed tooth plate reverses and resets under the restoring force of the reset assembly to ensure normal function next time.

[0011] The outer cover is located at the positioning assembly, and the two clamping arms are located on both sides of the guard teeth. The two clamping arms operate synchronously to lightly clamp the guard teeth to perform the final positioning of the guard teeth.

[0012] The beneficial technical effect of this solution is that this solution is used to correct the orientation of the protective teeth on the outer cover in the process before the top cover is closed on the outer cover, and finally position it relative to the position of the workbench so that the notch on the top cover is aligned with the protective teeth, thereby improving the combination efficiency of the top cover and the outer cover, increasing the success rate of closing, and reducing the scrap rate of the combined bottle cap.

[0013] Furthermore, the rotary cover assembly includes a twist head that drives the outer cover to rotate, a motor that drives the twist head to rotate, and a first cylinder that drives the motor to move up and down.

[0014] Furthermore, the reset assembly includes a fixed shaft and a rotating shaft that drives the fixed gear plate to rotate, and the fixed shaft is provided with a reset spring that drives the rotating shaft to rotate and reset.

[0015] Furthermore, the return spring is preferably a planar spiral spring, the inner ring of the planar spiral spring is fixedly connected to the fixed shaft, and the outer ring of the planar spiral spring is fixedly connected to the rotating shaft.

[0016] Furthermore, the shifting assembly includes a shifting rod and a cone-shaped shifting core connected to one end of the shifting rod close to the outer cover.

[0017] Furthermore, the first movable assembly includes a connecting seat and a second cylinder, the second cylinder is connected to the connecting seat, and the connecting seat is connected to the mounting seat.

[0018] Furthermore, the mounting base is slidably connected to the connecting base. The end of the connecting base away from the support column is connected to a vertical plate. The vertical plate is horizontally slidably connected to a guide rod. One end of the guide rod is connected to the mounting base, and the other end of the guide rod is provided with a stopper. The guide rod is sleeved with a spring, and the spring is located between the vertical plate and the mounting base. When the fixed tooth plate positions the protective teeth, the fixed tooth plate of the mounting base contacts the outer wall of the outer cover, and the mounting base retracts. At this time, the spring acts as a buffer, so that the contact between the mounting base and the outer cover is slowed down to prevent damage. BRIEF DESCRIPTION OF THE DRAWINGS
