Description

Technical Field

[0001] This utility model relates to the field of bottle cap production, and in particular to an automatic capping device for flip-top caps. Background Technology

[0002] Bottle caps are a crucial component of food and beverage packaging and the first point of contact consumers have with the product. They maintain the airtightness of the contents, provide tamper-evident protection, and ensure safety. Therefore, they are widely used in bottled products, making bottle caps a key product in bottled packaging and an upstream industry for the food, beverage, wine, chemical, and pharmaceutical industries. Early bottle cap development utilized cork, tin crown caps, and screw caps. Today, the industry has expanded to include aluminum long-neck caps, aluminum caps for carbonated beverages, hot-fill aluminum caps, aluminum caps for injection solutions, pharmaceutical caps, flip-top ring caps, safety claw caps, and plastic bottle caps, among others.

[0003] For example, patent (CN 216918548 U) discloses an automatic pressing device for flip-top bottle caps, including a running track and a pressing device located above the running track; the pressing device includes a pressing head and a cylinder, with the pressing head located below the cylinder, and the cylinder driving the pressing head to move up and down; a laser emitter is provided on one side of the running track, and a laser sensor is provided on the other side, with the laser emitter and laser sensor located directly below the pressing head; the laser sensor is electrically connected to the running track; the technical advantages are: the operator only needs to place the bottle cap on the running track, and when the bottle cap is conveyed to directly below the pressing device, it blocks the laser emitter. When the laser sensor can no longer detect the light emitted by the laser emitter, the running track stops, and the pressing head punches downwards to complete the bottle cap sealing; the overall structure is simple, the operation is convenient, and it can be widely promoted.

[0004] When using the above technology, the following technical problems were found in the existing technology: the existing automatic capping equipment uses a conveyor belt to transport the bottle and cap to the capping mechanism for pressure application. However, the existing technology is not convenient for positioning the bottle, thus lacking the stability of bottle positioning, which easily leads to bottle displacement and a significant reduction in capping accuracy. Therefore, we designed an automatic capping equipment to provide another technical solution to the above technical problems. Summary of the Invention

The end of the two positioning blocks that are close to each other is slidably connected to the bottle. A drive block is fixed at the end of the two guide rods that are far apart from each other.

[0007] In a preferred embodiment of the automatic capping device for flipping bottles provided by this utility model, the bottom end of the conveyor table is provided with a positioning mechanism for limiting the bottle body.

[0008] In a preferred embodiment of the automatic capping device for flipping lids provided by this utility model, a servo motor is assembled at the bottom of the conveyor table, and a worm gear is fixed at the output end of the servo motor. The two ends of the worm gear are rotatably connected to the conveyor table, and the outer side of the worm gear is meshed with a worm wheel.

[0009] In a preferred embodiment of the automatic capping device for flip-tops provided by this utility model, the guide groove is arc-shaped.

[0010] In a preferred embodiment of the automatic capping device for flipping lids provided by this utility model, U-shaped guide blocks are fixed on both sides of the conveyor table, and the inner side of the U-shaped guide blocks is slidably connected to the linkage block.

[0011] In a preferred embodiment of the automatic capping device provided by this utility model, a pressing mechanism for applying pressure to the bottle cap is provided on the inner side of the U-shaped frame.

[0027] In use, the bottle cap is placed on the bottle body, and then the bottle body is placed on the conveyor belt 4 in sequence. The conveyor belt 4 is then started to transport the bottle body to the pressure plate 5 for pressing. Then, the positioning mechanism is started to drive the drive block 6, guide rod 14 and positioning block 13 to position the bottle body, so as to improve the stability of the bottle body and prevent the deviation during the pressing process. Finally, the electric push rod 3 drives the pressure plate 5 to apply pressure to the bottle cap, thereby improving the tightness between the bottle cap and the bottle body.

[0028] The bottom end of the conveyor 1 is provided with a positioning mechanism for limiting the bottle body. The positioning mechanism includes a linkage block 7, a servo motor 11, a worm gear 12, a transmission disk 8 and a worm wheel 10.
