Description

Technical Field

[0001] This utility model relates to the technical field of plastic bottle cap production equipment, and more specifically, to a feeding device for producing beverage bottle caps. Background Technology

[0002] A beverage bottle cap is a device used to seal beverage bottles. Its main function is to maintain the freshness and hygiene of the beverage inside, preventing the intrusion of external dust, oxygen, and moisture. Currently, for injection-molded bottle caps, the unloading and unloading of parts from the injection molding machine mold is usually done by a robotic arm. However, for plastic parts like bottle caps, multiple caps can typically be injection molded from a single mold. If a robotic arm were used to unload and pick them up one by one, it would require multiple trips to unload all the caps formed in one operation.

[0003] To improve the efficiency of the bottle cap feeding process, the feeding device needs to be improved. By using a movable adjustable spacing transfer mechanism, the transfer efficiency can be improved. Therefore, we propose a feeding device for beverage bottle cap production to solve the above-mentioned problems. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a feeding device for beverage bottle cap production. It uses the power output of a servo motor to drive the connecting seat to rotate, keeping the vacuum suction plate parallel to the mold. Then, the height of the vacuum suction plate is adjusted by a second double-acting cylinder, the vacuum pump is turned on, and the slide block is pushed by a first double-acting cylinder to slide in conjunction with the first guide rod. The negative pressure generated at the end of the suction head adsorbs the bottle caps. Then, the movable end of the first double-acting cylinder retracts to remove the bottle caps from the mold. The transfer efficiency is improved by a movable adjustable spacing transfer mechanism.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A feeding device for producing beverage bottle caps includes a mold transfer box and a feeding box that is conductively connected to the mold transfer box. A feeding mechanism is installed on the top wall of the inner cavity of the feeding box.

[0009] The feeding mechanism includes a first connecting frame symmetrically fixedly connected to the top wall of the inner cavity of the feeding machine box, a first guide rod symmetrically installed between the first connecting frames, a slide block slidably connected to the first guide rod, a first double-acting cylinder installed between the slide block and the first connecting frame, a second double-acting cylinder installed on the lower surface of the slide block, a connecting bracket installed on the movable end of the second double-acting cylinder, a servo motor installed on the connecting bracket, a connecting seat that is drivenly connected to the power output end of the servo motor and rotatably connected to the connecting bracket, a vacuum suction plate that is fixedly connected to the connecting seat and has a hollow inner cavity, and suction heads that are arrayed on the surface of the vacuum suction plate.

[0010] A vacuum pump is installed on the top of the unloading machine box, and the pumping end of the vacuum pump is electrically connected to the vacuum suction plate.

[0011] Furthermore, both ends of the connecting seat are fixedly connected to shaft heads, and the shaft heads are connected to the connecting bracket via bearings.

[0012] Furthermore, one of the shaft heads passes through the connecting seat, and the through end of the connecting seat is connected to the power output end of the servo motor via a coupling.

[0013] Furthermore, the top of the vacuum suction plate is conductively connected to a connector, and the connector is connected to the suction end of the vacuum pump via a flexible hose.

[0014] Furthermore, a rubber gasket is embedded at the end of the suction head.

[0015] Furthermore, a transfer mechanism is installed on the bottom wall of the inner cavity of the unloading machine box;

[0017] Furthermore, the two symmetrically arranged fixing frames correspond to the suction heads.

[0018] 3. Beneficial Effects

[0019] Compared with existing technologies, the advantages of this utility model are:

[0020] (1) In this scheme, after the forming mold transfers the formed beverage bottle caps to the corresponding part of the unloading machine box through the mold transfer box, the power output end of the servo motor drives the connecting seat to rotate with the connecting bracket, so that the vacuum suction plate and the mold are kept parallel. Then, the height of the vacuum suction plate is adjusted by the second double-acting cylinder, the vacuum pump is turned on, and the slide block is pushed by the first double-acting cylinder to slide with the first guide rod, so that the vacuum suction plate moves closer to the mold until the suction head abuts against the bottle caps on the mold. The negative pressure generated at the end of the suction head adsorbs the bottle caps. Then, the movable end of the first double-acting cylinder retracts to remove the bottle caps from the mold. At the same time, the servo motor drives the vacuum suction plate to flip downwards to transfer the removed bottle caps. The transfer efficiency is improved by the movable adjustable spacing transfer mechanism.

[0021] (2) In this scheme, after the vacuum suction plate is parallel and aligned with the tray, the first double-acting cylinder drives the vacuum suction plate to move downward until the bottle cap is placed at the fixed frame. Then the vacuum pump stops working, so that the fixed frame fixes the bottle cap. Then the stepper motor drives the lead screw to rotate in conjunction with the second connecting frame, so that the movable seat slides in conjunction with the second guide rod, thereby driving the tray to move synchronously to the next process, which improves the transfer efficiency.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0032] Example:

[0033] Please see Figure 1-7 A feeding device for producing beverage bottle caps includes a mold transfer box 1 and a feeding box 2 that is conductively connected to the mold transfer box 1. A feeding mechanism is installed on the top wall of the inner cavity of the feeding box 2.

[0034] The unloading mechanism includes a first connecting frame 3 symmetrically fixedly connected to the top wall of the inner cavity of the unloading machine box 2, a first guide rod 4 symmetrically installed between the first connecting frames 3, a slide 5 slidably connected to the first guide rod 4, a first double-acting cylinder 6 installed between the slide 5 and the first connecting frame 3, a second double-acting cylinder 7 installed on the lower surface of the slide 5, a connecting bracket 8 installed on the movable end of the second double-acting cylinder 7, a servo motor 9 installed on the connecting bracket 8, a connecting seat 10 that is connected to the power output end of the servo motor 9 and rotatably connected to the connecting bracket 8, a vacuum suction plate 12 that is fixedly connected to the connecting seat 10 and has a hollow inner cavity, and suction heads 13 that are arrayed on the surface of the vacuum suction plate 12.

[0035] A vacuum pump 16 is installed on the top of the unloading machine box 2, and the suction end of the vacuum pump 16 is connected to the vacuum suction plate 12.

[0036] It should be noted that, in use, the unloading device for beverage bottle cap production, after the forming mold transfers the formed beverage bottle caps to the corresponding part of the unloading machine 2 via the mold transfer box 1, the power output end of the servo motor 9 drives the connecting seat 10 to rotate in conjunction with the connecting bracket 8, so that the vacuum suction plate 12 is kept parallel to the mold. Then, the height of the vacuum suction plate 12 is adjusted by the second double-acting cylinder 7, the vacuum pump 16 is turned on, and the first double-acting cylinder 6 pushes the slide 5 to slide in conjunction with the first guide rod 4, so that the vacuum suction plate 12 moves closer to the mold until the suction head 13 abuts against the bottle cap on the mold. The negative pressure generated at the end of the suction head 13 adsorbs the bottle cap, and then the movable end of the first double-acting cylinder 6 retracts to remove the bottle cap from the mold. At the same time, the servo motor 9 drives the vacuum suction plate 12 to flip downwards to transfer the removed bottle cap. The transfer efficiency is improved by the movable adjustable spacing transfer mechanism.

[0037] like Figure 3 , Figure 4 As shown, both ends of the connecting seat 10 are fixedly connected to shaft heads 11, and the shaft heads 11 are connected to the connecting bracket 8 through bearings. One of the shaft heads 11 passes through the connecting seat 10, and the through end of the connecting seat 10 is connected to the power output end of the servo motor 9 through a coupling.

[0038] It should be noted that this reduces the friction between the shaft head 11 and the connecting bracket 8, ensures the rotation accuracy of the connecting seat 10, and enables the power transmitted by the servo motor 9 to be transferred to the connecting seat 10.

[0039] like Figure 1 , Figure 5 As shown, the top of the vacuum suction plate 12 is connected to a connector 15, and the connector 15 is connected to the suction end of the vacuum pump 16 through a hose. The end of the suction head 13 is inlaid with a rubber gasket 14.

[0040] It should be noted that by using the rubber gasket 14, the gap between the suction head 13 and the bottle cap can be filled, which facilitates the use of negative pressure to suck up the bottle cap.

[0041] like Figure 2 , Figure 6 , Figure 7 As shown, a transfer mechanism is installed on the bottom wall of the inner cavity of the unloading machine box 2;

[0042] The transfer mechanism includes a second connecting frame 17 symmetrically installed on the bottom wall of the inner cavity of the unloading machine box 2, a lead screw 18 rotatably connected between the second connecting frames 17, a second guide rod 20 disposed on both sides of the lead screw 18 and fixedly connected to the second connecting frame 17 at its end, a stepper motor 19 installed on one of the second connecting frames 17 and whose power output end is connected to the lead screw 18, a movable seat 23 slidably connected to the second guide rod 20 and screwed to the book search lead screw 18, a tray 21 fixedly connected to the movable seat 23, and a fixed frame 22 fixedly connected to the tray 21.

[0043] The two symmetrically arranged fixing frames 22 correspond to the suction head 13;

[0044] It should be noted that after the vacuum suction plate 12 is parallel and aligned with the tray 21, the first double-acting cylinder 6 drives the vacuum suction plate 12 to move downward until the bottle cap is placed at the fixed frame 22. Then, the vacuum pump 16 stops working, so that the fixed frame 22 fixes the bottle cap. Then, the stepper motor 19 drives the lead screw 18 to rotate in conjunction with the second connecting frame 17, so that the movable seat 23 slides in conjunction with the second guide rod 20, thereby driving the tray 21 to move synchronously to the next process.

[0045] In use: After the molding mold transfers the molded beverage bottle caps to the corresponding part of the unloading machine box 2 via the mold transfer box 1, the power output end of the servo motor 9 drives the connecting seat 10 to rotate in conjunction with the connecting bracket 8, so that the vacuum suction plate 12 is kept parallel to the mold. Then, the height of the vacuum suction plate 12 is adjusted by the second double-acting cylinder 7, the vacuum pump 16 is turned on, and the first double-acting cylinder 6 pushes the slide 5 to slide in conjunction with the first guide rod 4, so that the vacuum suction plate 12 moves closer to the mold until the suction head 13 abuts against the bottle cap on the mold. The negative pressure generated at the end of the suction head 13 adsorbs the bottle cap. Then, the movable end of the first double-acting cylinder 6 retracts to remove the bottle cap from the mold. At the same time, the servo motor 9 drives the vacuum suction plate 12 to flip downward to transfer the removed bottle cap.

[0046] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
