[0002] At present, during the production of cosmetics, many cosmetics need to be packaged and stored in packaging bottles. Cosmetic packaging bottles come in various types. Generally, a cosmetic packaging bottle includes multiple components and needs to be assembled.

[0003] In the related art, referring to Figure 1 , a cosmetic packaging bottle is composed of components such as a pump head assembly 11, a tank body 12, a bottle body 13, a cap 14, and a conduit 15. The pump head assembly 11 further includes a pump head cover 111 and a pump head 112. The pump head cover 111 is combined and snap - connected to the first end of the pump head 112. The second end of the pump head 112 serves as the cap of the bottle body 13 and is screwed onto the opening end of the bottle body 13. The tank body 12 is disposed inside the bottle body 13 and fixed to the second end of the pump head 112. One end of the tank body 12 facing away from the pump head 112 is provided with an opening. The cap 14 is covered and snap - connected to the opening of the tank body 12. One end of the cap 14 facing away from the opening of the tank body 12 is connected to the conduit 15.

[0004] When assembling this cosmetic packaging bottle, the cap needs to be assembled onto the opening of the tank body. Currently, there are mainly two methods. One method is manual assembly, where an operator manually snap - connects the cap onto the opening of the tank body. The other method is equipment assembly. After positioning the pump head assembly, the tank body is aligned with the cap, and the cap is pressed onto the opening of the tank body using the equipment.

[0005] Among them, the method of manual assembly has low efficiency, is time - consuming and laborious, and the labor intensity of the operator is high. For the method of equipment assembly, the pump head assembly needs to be positioned, and the tank body needs to be disassembled after assembly. In the prior art, the positioning tooling is relatively complex, resulting in inconvenient disassembly and assembly of the tank body and affecting the production efficiency of cosmetics.

The bottom end of the frame 21 is a working platform. The cylinder 22 is installed at the top of the frame 21. The push rod of the cylinder 22 is the output end 221 of the press. In this embodiment, the sealing cap clamping assembly 3 is welded and fixed to the output end 221 of the press. The cylinder 22 drives the output end 221 of the press to drive the sealing cap clamping assembly 3 to reciprocate up and down to complete the operation of clamping the sealing cap 14 and pressing and assembling. In other embodiments, the sealing cap clamping assembly 3 can also be clamped and fixed to the output end 221 through a fixture fixed on the output end 221.

[0042] The positioning device 4 includes a positioning seat 41. A positioning hole 411 for positioning the pump head assembly 11 is provided on one side of the positioning seat 41 facing the output end 221 of the press body 2. The size of the positioning hole 411 matches the size of the pump head assembly 11, facilitating the pump head assembly 11 to better determine its position in the positioning hole 411. When the pump head assembly 11 is positioned by the positioning hole 411, the opening of the tank body 12 faces the sealing cap clamping assembly 3.

[0043] In this embodiment, an access port 412 communicating with the positioning hole 411 is provided on the side wall of the positioning seat 41. The pump head assembly 11 can be moved into or out of the positioning hole 411 from the access port 412. This design makes the loading and unloading process of the pump head assembly 11 more convenient and effectively improves the operation efficiency. In other embodiments, the pump head assembly 11 can be directly taken out from the positioning hole 411.

In other embodiments, the V-shaped block 431 can be magnetically attracted to the base 42 by its own magnetism.

[0047] The implementation principle of this embodiment is as follows: The accurate positioning of the pump head assembly 11 is achieved by using the positioning device 4, and the quick and accurate picking and pressing of the capping 14 are achieved by the capping clamping assembly 3, greatly improving the quality and efficiency of assembly. Its main advantages are that it not only solves the problems of low positioning accuracy and complex operation in traditional manual operations, but also further improves the practicality and market competitiveness of the cosmetic packaging bottle assembly equipment.

[0048] Embodiment 2

[0049] The difference between this embodiment and the first embodiment is that: a T-shaped slot 421 is provided on the base 42 ; a locking member 6 is additionally provided; and a through hole 4311 is provided on the V-shaped block 431 .

[0050] Reference Figure 5 and Figure 6 A T-slot 421 is provided on the base 42, and the T-slot 421 extends vertically along the base 42. The V-block 431 can slide along the extension direction of the T-slot 421. A locking member 6 for locking the position of the V-block 431 is provided between the groove wall of the T-slot 421 and the V-block 431. The locking member 6 is a threaded bolt 61 and a nut 62. The bolt head of the bolt 61 can be clamped in the T-slot 421, so that the bolt 61 can slide along the extension direction of the T-slot 421.

[0051] A through hole 4311 is provided at the V-shaped tip of the V-block 431 for the bolt 61 to pass through. The bolt 61 passes through the through hole 4311 and is threadedly engaged with the nut 62. The nut 62 abuts against the side of the V-block 431 away from the T-slot 421. When the bolt 61 and the nut 62 are loosened, the moving bolt 61 can drive the V-block 431 to move together, so that the position of the V-block 431 can be adjusted according to needs. Tightening the bolt 61 and the nut 62 can fix the V-block 431 on the base 42.

[0052] The implementation principle of this embodiment is that when the position of the V-block 431 on the base 42 needs to be adjusted, the V-block 431 is separated from the base 42 by loosening the bolts 61 and the nuts, and the position of the V-block 431 can be adjusted by moving the V-block 431 to slide along the T-slot 421. After the position of the V-block 431 is determined, the bolts 61 and the nuts are tightened to make the V-block 431 abut against the base 42, thereby fixing the V-block 431. This design makes it more convenient to adjust and fix the position of the positioning seat 41. Its main advantage is that it not only simplifies the adjustment process of the positioning device 4, but also ensures the accuracy and stability of the position of the positioning seat 41, further improving the applicability and reliability of the entire device.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
