Technical Field

[0001] This utility model relates to the field of aluminum-plastic bottle cap pressing technology, specifically to an auxiliary device for pressing aluminum-plastic bottle caps. Background Technology

[0002] In the packaging industry, aluminum-plastic bottle caps are widely used for bottle sealing in pharmaceuticals, food, cosmetics and other fields because they combine the high strength of aluminum with the sealing properties of plastic. They are tightly bonded together through mechanical pressure or heat sealing.

[0003] The aluminum-plastic bottle cap pressing device uses a pressing head to press the aluminum-plastic bottle cap to the bottle neck. Since the diameter of the bottle neck is different, the aluminum-plastic bottle cap used is also different. Therefore, in order to keep the aluminum-plastic bottle cap consistent, the operator needs to change the pressing head mold. However, the existing pressing head mold is generally fixed with bolts. If the pressing head mold is changed frequently, it is easy to cause stripping of the pressing head mold installation position. Moreover, the replacement operation is troublesome. In order to solve the above problems, an auxiliary device for pressing aluminum-plastic bottle caps is proposed. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figures 1-6 The illustrated aluminum-plastic bottle cap pressing auxiliary device includes a mounting base 1 and a pressing head mold 2, as well as a clamping mechanism 3. The mounting base 1 has through slots 4 on both sides, and the pressing head mold 2 has clamping slots 5 on both sides corresponding to the through slots 4. The through slots 4 and clamping slots 5 are used by the clamping mechanism 3 to assemble and disassemble the pressing head mold 2. The mounting base 1 is mounted on a semi-automatic vial capping machine and then fixedly connected to the hydraulic equipment on the semi-automatic vial capping machine. The hydraulic equipment drives the pressing head mold 2 on the mounting base 1 to rise and fall. During the rising and falling process, the pressing head mold 2 presses the aluminum-plastic bottle cap and the bottle neck together. The locking mechanism 3 penetrates through the through groove 4 and engages with the inside of the locking groove 5. The pressure head mold 2 is installed at the lower end of the mounting base 1 through the locking mechanism 3. The locking mechanism 3 is used to limit the position of the pressure head mold 2. After the through grooves 4 on both sides of the mounting base 1 are aligned with the locking grooves 5 on both sides of the pressure head mold 2, the locking mechanism 3 penetrates through the through groove 4 and engages with the locking groove 5 to achieve a detachable connection between the two. The locking mechanism 3 fixes the position of the pressure head mold 2 through the limiting action to ensure that the pressure head mold 2 does not shift during the pressing process. It replaces the traditional bolt fixing, simplifies the pressure head mold 2 replacement process, and can be quickly disassembled and assembled without tools, avoiding the problem of bolt stripping.

[0025] The locking mechanism 3 includes a locking rod 31. One end of the locking rod 31 passes through the through groove 4 and extends into the locking groove 5 opened in the pressure head mold 2. The other end of the locking rod 31 is fixedly connected to a limiting plate 32. One side of the limiting plate 32 is attached to the outer wall of the mounting base 1. The mounting base 1 is provided with a limiting component 33 that provides locking function for the limiting plate 32. One end of the locking rod 31 is inserted into the locking groove 5 and is tightly attached to the inside of the locking groove 5. The other end of the limiting plate 32 is attached to the outer wall of the mounting base 1 through the insertion between the locking rod 31 and the locking groove 5. Then, the limiting component 33 locks the position of the limiting plate 32 to prevent the locking rod 31 from loosening.

[0026] Four limiting components 33 are provided, symmetrically distributed in pairs on the mounting base 1 and located at both ends of the limiting plate 32. Each limiting component 33 includes a fixing block 331 fixed to the outer wall of the mounting base 1. A limiting rod 332 is movably connected to the surface of the fixing block 331, and the lower end of the limiting rod 332 is engaged with the limiting plate 32. The limiting component 33 also includes limiting grooves 333, which are respectively formed on the limiting plate 32 and the limiting rod 332. Magnetic blocks 334 are embedded within the limiting grooves 333. The movable shaft on the fixed block 331 allows the limiting rod 332 to be movably mounted on the fixed block 331. Subsequently, the limiting rod 332 on the fixed block 331 can be rotated and adjusted. According to the gravity of the locking rod 31, its lower end will be vertically downward, and then the lower end of the pull rod 6 will be locked on the limiting plate 32. The magnetic block 334 in the limiting groove 333 is magnetically attracted, which enhances the stability of the locking between the locking rod 31 and the limiting plate 32. The auxiliary fixing of the magnetic block 334 prevents the limiting rod 332 from accidentally disengaging when the equipment vibrates, thus improving reliability.

[0027] A pull rod 6 is fixedly connected to the surface of the limiting plate 32. The surface of the pull rod 6 is provided with anti-slip texture. Pulling the pull rod 6 on the surface of the limiting plate 32 can drive the locking rod 31 to move, which is convenient for operation. The anti-slip texture increases the friction between the pull rod 6 and the hand.

[0028] Positioning rods 7 are fixedly connected around the top of the pressure head mold 2. Positioning holes 8 are opened on the mounting base 1 at the positions corresponding to the positioning rods 7. The positioning rods 7 of the pressure head mold 2 are inserted into the positioning holes 8 of the mounting base 1 to ensure that the mold installation position is accurate. The position of the pressure head mold 2 is predetermined in advance, so as to facilitate the quick installation of the pressure head mold 2.

[0029] In practical use, when using the aluminum-plastic bottle cap pressing auxiliary device, first align the through grooves 4 on both sides of the mounting base 1 with the slots 5 of the pressing head mold 2. Hold the anti-slip pull rod 6 on the limiting plate 32 and push the locking rod 31 through the through groove 4 and into the slot 5 to initially fix the pressing head mold 2 at the lower end of the mounting base 1. Then rotate the limiting rod 332 on the fixing block 331 so that its lower end is locked into the limiting groove 333 of the limiting plate 32. Use the magnetic attraction of the magnetic block 334 to further lock the position of the limiting plate 32 and prevent the locking rod 31 from loosening, thus completing the mold installation. When it is necessary to replace the pressure head mold 2 of different specifications, simply pull the pull rod 6 outward to drive the locking rod 31 out of the locking groove 5, and at the same time rotate the limiting rod 332 to release the limit. The old mold can be quickly removed. Then, align the positioning rod 7 of the new mold with the positioning hole 8 of the mounting base 1 to complete the initial positioning. Repeat the above locking steps to quickly complete the installation. The whole process does not require the use of tools. A single person can complete the mold replacement in a short time, which significantly improves production efficiency and avoids the problems of easy stripping and cumbersome operation of traditional bolt fixing methods.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
