Description

Technical Field

[0001] This utility model belongs to the technical field of bottle cap stopper equipment, specifically relating to a flipping gasket mechanism for aluminum foil stoppers. Background Technology

[0002] Aluminum foil is a hot stamping material made by directly rolling metallic aluminum into thin sheets; in industry, PE composite aluminum foil gaskets are commonly used as gaskets for bottle caps or cup lids. Currently, aluminum foil gaskets are typically installed manually or by machine. For small and medium-sized factories, manually pinching and inserting the gasket poses a significant risk of breakage due to the fragility of the gasket material. Automated gasketing machines are bulky, cumbersome, and inefficient.

[0003] In existing technologies, machine-assisted insertion typically uses pneumatic suction to lift the gasket. Because the gasket is relatively light, it is quickly lifted by the airflow. The simple suction head rapidly and with low precision lifts the gasket, making it difficult to align properly when inserting it into the box lid. This not only damages the gasket but also affects the accuracy and efficiency of the insertion process. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a flipping pad mechanism for aluminum foil padding, so as to solve the technical problem of low precision in machine-applied aluminum foil padding.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: A flip-over gasket mechanism for aluminum foil stoppers includes a processing base, and a bottle cap conveying assembly, a limiting clamping assembly, an aluminum foil storage mechanism, and an adsorption feeding mechanism mounted on the processing base.

[0006] The bottle cap conveying assembly is used to convey the bottle caps to be processed. A limiting clamping assembly and an adsorption feeding mechanism are located on both sides of the bottle cap conveying assembly. The limiting clamping assembly can clamp the bottle caps to be processed when the bottle cap conveying assembly stops conveying.

[0007] The adsorption and feeding mechanism includes a lifting drive assembly, a mounting bracket, and a flipping adsorption assembly. The mounting bracket is fixed to the drive end of the lifting drive assembly. The flipping adsorption assembly is rotatably connected to the mounting bracket and can adsorb aluminum foil in the aluminum foil storage mechanism when the mounting bracket rises; when the mounting bracket descends, it flips downward to place the adsorbed aluminum foil into the bottle cap being processed.

[0008] Furthermore, the flipping adsorption assembly includes a flipping motor, a transfer bracket, and multiple adsorption elements. The transfer bracket is rotatably connected to the mounting bracket and can rotate under the drive of the flipping motor. Each adsorption element is arranged sequentially at intervals on the transfer bracket, and each has an air intake channel. The top of the air intake channel is connected to an external air intake pump via a pneumatic quick-connect plug.

[0009] Furthermore, the limiting clamping assembly includes a support bracket, a drive cylinder, an infrared detector, a first clamping plate, and a second clamping plate. The drive cylinder is fixed to the processing base via the support bracket. The first and second clamping plates are symmetrically arranged and fixed to the telescopic end of the drive cylinder and the conveying bracket, respectively. Both the first and second clamping plates have multiple slots that mate with the bottle caps being processed. The infrared detector is fixed to the top of the support bracket to detect the movement position of the bottle caps being processed.

[0010] Furthermore, a preliminary positioning component is provided on the side of the mounting bracket closest to the conveyor belt. The preliminary positioning component includes a positioning bracket and multiple positioning rods. The positioning bracket is located at the end of the mounting bracket closest to the conveyor belt inlet and is fixedly connected by screws. Each positioning rod is fixed to the mounting bracket at equal intervals.

[0011] Furthermore, the positioning bracket has mounting slots that mate with each positioning rod. The bottom of each positioning rod passes through the mounting slot and is arranged at equal intervals. Each positioning rod is provided with two limit nuts. The two limit nuts are respectively located on both sides of the mounting slot and are threaded into the positioning rod.

[0012] Furthermore, the aluminum foil storage mechanism includes a fixed support and a storage rack. The storage rack is fixed to the processing base by the fixed support and is located directly above the flipping adsorption assembly. Multiple discharge channels are provided on the storage rack. Each discharge channel is aligned with each adsorption component.

[0013] Furthermore, multiple limiting grooves are formed on the bottom inner wall of each of the aforementioned discharge channels. These limiting grooves are evenly distributed circumferentially along the axis of the discharge channel. Multiple limiting rods are respectively disposed within each limiting groove and are threaded into it.

[0014] Furthermore, each of the discharge channels is equipped with multiple storage rods at its opening. The storage rods are evenly distributed circumferentially along the axis of the discharge channel, forming a storage space that cooperates with the aluminum foil.

[0015] Furthermore, the bottle cap output assembly includes a conveyor bracket and a conveyor belt. The conveyor bracket is fixed to the main frame. Limiting plates are fixed to both sides of the top of the conveyor bracket. The adjacent sides of the two limiting plates are spaced apart, forming a conveying channel that mates with the bottle cap being processed. The conveyor belt is disposed within the conveying channel.

[0016] Compared with the prior art, the present invention has the following advantages: 1. This utility model utilizes a preliminary positioning component and a feeding and adsorption mechanism sequentially arranged on a mounting bracket. Simultaneously, a limiting clamping component is provided on one side of the feeding and adsorption mechanism. This ensures that when the bottle caps being processed are input via the conveyor belt, the distance between each bottle cap is first adjusted by the preliminary positioning component, and then the limiting clamping component further restricts the position of each bottle cap, preventing any misalignment between the bottle caps and the adsorption components in the feeding and adsorption mechanism, thus ensuring the accuracy of cap insertion.

[0017] 2. This utility model features multiple limiting grooves on the inner bottom wall of the discharge trough on the storage rack. These limiting grooves are evenly distributed circumferentially along the axis of the discharge trough. Multiple limiting rods are respectively installed in each limiting groove and threaded into them. When the limiting rods are tightened inward, their inner ends extend into the discharge trough, supporting the aluminum foil stored there and preventing it from falling naturally under gravity. When the suction cup adsorbs the aluminum foil, it deforms, allowing it to be smoothly discharged from the bottom of the discharge trough. This ensures smooth aluminum foil discharge while avoiding excessive deformation and tearing that can occur with manual methods. Attached Figure Description

[0020] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper side", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figure 1 and 2 As shown, a flipping gasket mechanism for aluminum foil stoppers includes a processing base 1, and a bottle cap conveying assembly 2, a limiting clamping assembly 3, an aluminum foil storage mechanism 4, and an adsorption feeding mechanism 5 mounted on the processing base 1. The bottle cap conveying assembly 2 is used to convey the bottle caps to be processed. The limiting clamping assembly 3 and the adsorption feeding mechanism 5 are symmetrically arranged on both sides of the bottle cap conveying assembly 2.

[0023] The limiting clamping component 3 can clamp the bottle cap being processed when the bottle cap conveying component 2 stops conveying. The adsorption feeding mechanism 5 is used to adsorb the aluminum foil in the aluminum foil storage mechanism 4 and put it into the bottle cap being processed.

[0024] In this embodiment, the aluminum foil storage mechanism 4 is positioned directly above the adsorption and feeding mechanism. The adsorption end of the adsorption and feeding mechanism can lift upwards to adsorb the aluminum foil in the aluminum foil storage mechanism 4. Subsequently, the adsorption end flips and descends, placing the aluminum foil into the corresponding bottle cap to be processed.

[0025] like Figure 2 As shown, the bottle cap output assembly includes a conveyor bracket 2-1 and a conveyor belt 2-2. The conveyor bracket 2-1 is fixed to the main frame. Limiting plates 2-3 are fixed to both sides of the top of the conveyor bracket 2-1. The two limiting plates 2-3 are spaced apart on adjacent sides, forming a conveying channel that mates with the bottle caps being processed. The conveyor belt 2-2 is disposed within the conveying channel and is used to transport externally input bottle caps.

[0026] In this embodiment, the width of the conveying channel is greater than the diameter of the bottle cap being processed, ensuring that the bottle cap can be conveyed smoothly while avoiding interference with the limiting clamping component 3 during conveying.

[0027] like Figure 3As shown, the limiting clamping assembly 3 includes a support bracket 3-1, a drive cylinder 3-2, an infrared detector, a first clamping plate 3-3, and a second clamping plate. The drive cylinder 3-2 is fixed to the processing base 1 via the support bracket 3-1. The first clamping plate 3-3 and the second clamping plate are symmetrically arranged and fixed to the telescopic end of the drive cylinder 3-2 and the conveying bracket 2-1, respectively. Both the first clamping plate 3-3 and the second clamping plate have multiple slots that mate with the bottle caps being processed, for clamping the bottle caps. The infrared detector is fixed to the top of the support bracket 3-1 to detect whether the bottle caps have moved to the positions of the first clamping plate 3-3 and the second clamping plate.

[0028] During the processing, when the bottle cap being processed moves to the position of the limiting clamping component 3 under the drive of the conveyor belt 2-2, the telescopic end of the drive cylinder 3-2 drives the first clamping plate 3-3 to move outward, and cooperates with the second clamping plate to form a clamping and fixing of the bottle cap being processed, so that the adsorption feeding mechanism 5 can put aluminum foil into the bottle cap being processed.

[0029] like Figure 2 and 4 As shown, the adsorption and feeding mechanism 5 includes a lifting drive assembly 5-1, a mounting bracket 5-2, and a flipping adsorption assembly. The flipping adsorption assembly is fixed to the drive end of the lifting drive assembly 5-1 via the mounting bracket 5-2, and can rise or fall under the drive of the lifting drive assembly 5-1 to transfer the aluminum foil in the aluminum foil storage mechanism 4 to the bottle cap being processed.

[0030] The flip-adsorption assembly includes a flip motor 5-3, a transfer bracket 5-4, and multiple adsorption elements 5-5. The transfer bracket 5-4 is rotatably connected to the mounting bracket 5-2 and can rotate under the drive of the flip motor 5-3. The transfer bracket 5-4 is connected to the power output shaft of the flip motor 5-3 via a coupling. The adsorption elements 5-5 are arranged sequentially at intervals on the transfer bracket 5-4 and can rotate synchronously with the transfer bracket 5-4. Each adsorption element 5-5 has an air intake channel. The top of the air intake channel is connected to an external air intake pump via a pneumatic quick-connect plug. The bottom of the air intake channel has a suction cup.

[0031] During actual processing, the suction component 5-5 on the transfer bracket 5-4 has two states driven by the flipping motor 5-3: a picking state and a loading state. When the suction component 5-5 is in the picking state, the suction cup on the suction component 5-5 is directly opposite the discharge port of the aluminum foil storage mechanism 4. The suction component 5-5 rises under the drive of the lifting drive assembly 5-1 and completes the adsorption of aluminum foil under the drive of the external suction pump. Subsequently, the suction component 5-5 flips 180° under the drive of the flipping motor 5-3, switching from the picking state to the loading state. The suction component 5-5 descends under the drive of the lifting drive assembly 5-1, completing the placement of the adsorbed aluminum foil into the bottle cap to be processed.

[0032] Furthermore, a preliminary positioning component 6 is provided on the side of the mounting bracket 5-2 near the conveyor belt 2-2, which is used to initially position each input bottle cap to be processed, limit the spacing between each bottle cap to be processed, and facilitate the subsequent positioning and clamping of the limiting clamp.

[0033] like Figure 4 , 5 As shown in Figure 6, the initial positioning assembly 6 includes a positioning bracket 6-1 and multiple positioning rods 6-2. The positioning bracket 6-1 is located at one end of the mounting bracket 5-2 near the input port of the conveyor belt 2-2 and is fixedly connected by screws. The positioning bracket 6-1 has mounting slots that mate with each positioning rod 6-2. The bottom of each positioning rod 6-2 passes through the mounting slot and is arranged at equal intervals. Each positioning rod 6-2 is provided with two limiting nuts 6-3. The two limiting nuts 6-3 are respectively located on both sides of the mounting slot and are threaded into the positioning rod 6-2, enabling the positioning rod 6-2 to be locked in position when tightened.

[0034] During actual processing, the operator adjusts the distance between adjacent positioning rods 6-2 according to the spacing of the slots on the first clamping plate 3-3 and the second clamping plate. After adjustment, each positioning rod 6-2 is locked in position by two limiting nuts 6-3. When multiple bottle caps are input sequentially, each positioning rod 6-2 descends under the drive of the lifting drive assembly 5-1 and initially abuts against the conical wall of each bottle cap. Each positioning rod 6-2 continues to descend gradually, adjusting the distance between adjacent bottle caps during the descent. After the adjustment of the adjacent distance between the bottle caps is completed, each positioning rod 6-2 rises under the drive of the lifting drive assembly 5-1, allowing each bottle cap to be transported to the position of the limiting clamping assembly 3 according to the set spacing under the drive of the conveyor belt 2-2. The limiting clamping assembly 3 clamps each bottle cap.

[0035] like Figure 2 and 4As shown, the aluminum foil storage mechanism 4 includes a fixed bracket and a storage rack 4-1. The storage rack 4-1 is fixed to the processing base 1 by the fixed bracket and is located directly above the flipping adsorption assembly. Multiple discharge channels 4-2 are provided on the storage rack 4-1. Each discharge channel 4-2 is aligned with each adsorption component 5-5. The discharge port is located at the bottom of the discharge channel 4-2.

[0036] Multiple limiting grooves are formed on the inner bottom wall of each discharge channel 4-2. These limiting grooves are evenly distributed circumferentially along the axis of the discharge channel 4-2. Multiple limiting rods are respectively installed in each limiting groove and are threaded into them. When the limiting rods are tightened inward, their inner ends extend into the discharge channel 4-2, supporting the aluminum foil stored within and preventing it from falling naturally under gravity. When the suction cup adsorbs the aluminum foil, the foil deforms, allowing it to be smoothly discharged from the bottom of the discharge channel 4-2. After discharge, it returns to its original shape, thus allowing it to be smoothly added to the bottle cap being processed.

[0037] In this embodiment, each discharge channel 4-2 is equipped with multiple storage rods 4-3 at its opening. The storage rods 4-3 are evenly distributed circumferentially along the axis of the discharge channel 4-2, forming a storage space that cooperates with the aluminum foil, allowing workers to place more aluminum foil on the storage rack 4-1.

[0038] This embodiment provides a non-essential technical feature: the lifting drive assembly 5-1 includes a lifting motor and a transmission assembly. The lifting motor is fixed on the processing base 1 and drives the transmission assembly to raise or lower the mounting bracket 5-2. In this embodiment, the transmission assembly adopts a crank-slider structure, so that when the drive end of the lifting motor rotates, it can smoothly drive the mounting bracket 5-2 to rise or fall through the crank-slider structure.

[0039] The working principle of this utility model is as follows: Workers place the bottle caps to be processed in groups of four on conveyor belt 2-2. When each bottle cap reaches the position of the initial positioning component 6, conveyor belt 2-2 stops conveying, and each positioning rod 6-2 descends under the drive of the lifting drive component 5-1, initially abutting against the conical wall of each bottle cap. Each positioning rod 6-2 continues to descend gradually, adjusting the spacing between adjacent bottle caps during the descent. After the spacing between adjacent bottle caps is adjusted, each positioning rod 6-2 rises under the drive of the lifting drive component 5-1, allowing each bottle cap to be transported to the position of the limiting clamping component 3 according to the set spacing under the drive of conveyor belt 2-2.

[0040] When the bottle cap being processed moves to the position of the limiting clamping assembly 3 under the drive of the conveyor belt 2-2, the telescopic end of the drive cylinder 3-2 drives the first clamping plate 3-3 to move outward, and cooperates with the second clamping plate to form a clamping and fixing of the bottle cap being processed, so that the adsorption feeding mechanism 5 can put aluminum foil into the bottle cap being processed.

[0041] Subsequently, the mounting bracket 5-2 rises under the drive of the lifting drive assembly 5-1. Simultaneously, each adsorption component 5-5, driven by the flipping motor 5-3, moves towards the discharge port of the aluminum foil storage mechanism 4. The adsorption components 5-5 rise under the drive of the lifting drive assembly 5-1 and, driven by an external suction pump, complete the adsorption of aluminum foil. Then, the adsorption components 5-5 flip 180° under the drive of the flipping motor 5-3, switching from the material-picking state to the material-feeding state. The adsorption components 5-5 descend under the drive of the lifting drive assembly 5-1, completing the placement of the adsorbed aluminum foil into the bottle cap to be processed.

[0042] After the aluminum foil is inserted, the first clamping plate 3-3 and the second clamping plate release their grip on the bottle cap being processed, allowing it to be smoothly output via the conveyor belt 2-2.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
