Embodiment 1

[0035] like Figures 1 to 2 As shown, this embodiment provides a multi-color sealing bottle cap forming device, including several screw reciprocating plasticizing injection devices filled with different materials, an injection nozzle 2 and a conduit 3 . In this embodiment, the number of screw reciprocating plasticizing injection devices is two, which are the first screw reciprocating plasticizing injection device 11 and the second screw reciprocating plasticizing injection device 12; the first screw reciprocating plasticizing injection device 11 includes a first hopper 111, a first screw 112, a first barrel 113, the first hopper 111 is arranged on the first barrel 113, and is used as a feeding port; the first barrel 113 is provided with a first screw 112, The first screw 112 is in clearance fit with the first barrel 113 . A driving device is connected to the first screw 112, which can drive the screw to rotate and extrude. In this embodiment, the driving device is preferably ...

Embodiment 2

[0040] like image 3 As shown, this embodiment refers to Embodiment 1, and provides a multi-color sealing bottle cap molding device. The difference from Embodiment 1 is that in this embodiment, a third screw reciprocating plasticizing injection device 13 is also provided. , including the third hopper 131, the third screw 132, the third barrel 133, the third material 43 is installed in the third screw reciprocating plasticizing injection device 13, and the third material 43 passes through the third conduit 33 and the injection nozzle 2. The access port 213 is connected and merged at the injection end 22 ; the structure of the third screw reciprocating plasticizing injection device 13 is consistent with the working process and the first screw reciprocating plasticizing injection device 11 .

Embodiment 3

[0042] like Figure 4 As shown, this embodiment refers to Embodiment 1, and provides a multi-color sealing bottle cap forming device, which is different from Embodiment 1 in that a plurality of injection nozzles 2 are provided in this embodiment. According to the present invention, the number of corresponding injection nozzles can be set according to the number of injection cavities on the injection mold, so as to complete the injection molding work.

Abstract

The invention discloses a multicolor packaging bottle cap forming device and a process thereof. The forming device comprises a plurality of screw reciprocating plasticizing injection devices containing different materials, injection nozzles and guide pipes. Each screw reciprocating plasticizing injection device comprises a charging barrel, a hopper and a screw, wherein the hopper is arranged on the charging barrel, and the screw is arranged in the charging barrel and is in clearance fit with the screw. Material connecting inlets are formed in the injection nozzles and connected with the multiple screw reciprocating plasticizing injection devices correspondingly. The material connecting inlets converge at injection ends of the injection nozzles correspondingly and are connected with discharging outlets of the charging barrels through the guide pipes correspondingly. The multicolor packaging bottle cap forming process provided by the invention adopts one-time injection molding, the process flow is short, and the process is suitable for large-scale industrial mass production.

Description

technical field [0001] The invention relates to the technical field of packaging, and more particularly, to a multi-color packaging bottle cap forming device and a process thereof. Background technique [0002] With the improvement of people's living standards, in daily life, the requirements for the function and appearance of packaging are increasing day by day. For example, when using liquids, the requirements for the opening of liquid bottle caps and the functional requirements of the caps are getting higher and higher. Among the existing products, most of the bottle caps for liquid packaging use single-color caps with monotonous colors. [0003] In the prior art, in order to change the current situation of using single-color caps with monotonous colors in liquid packaging, a process scheme for forming multi-color bottle caps is proposed. The Chinese Patent Publication No. CN2649497 discloses a multi-color embedded step-by-step method to highlight the logo of the bottle...
