Problems solved by technology

When using dehydration bonding, the bonding surface is directly on the baffle and the upper cover, which is easy to cause the pacifier to be squeezed and deformed, the appearance is not beautiful, and the processing is difficult; while using the glue bonding process, there will inevitably be some glue residue On the pacifier, it will affect the health of the child, and at the same time, it is prone to weak bonding
And when the material PP plastic (polypropylene) is used for secondary injection molding, its performance is unstable and it is prone to poor welding, which affects the appearance and safety of use.

Embodiment 1

[0026] refer to figure 1 and figure 2 : the processing method of the pacifier, the pacifier comprises a pacifier head 1, a baffle plate 2 and an upper cover 4, and the pacifier processing steps are as follows:

[0027] a. Install the injection mold on the LK 130T horizontal injection molding machine to inject the nipple 1 and the baffle 2 respectively;

[0028] b. Install the injection mold on the LK 130T horizontal injection molding machine to perform secondary injection molding on the upper cover 4;

[0029] c. Cooperate and install the nipple 1 after injection molding in step a and the baffle plate 2 in step a;

[0030] d. Install the upper cover 4 in step b with the nipple 1 and the baffle 2 in step c, and the upper cover 4 and the baffle 2 seal the nipple 1;

[0031] e. The baffle plate 2 and the upper cover 4 in step d are welded by ultrasonic waves.

[0032] The raw material used for the nipple 1 is silica gel, the base material for the secondary injection mol...

Embodiment 2

[0043] The processing method of the pacifier is the same as that of Example 1, the only difference being that when the baffle plate 2 and decorative part 5 in step d are ultrasonically welded to the upper cover 4 in step e, the delay time of the ultrasonic welding process is 1s, and the welding time is 1s. The time is 1, the curing time is 1.4s, and the working pressure is 5KPA.

Embodiment 3

[0045] The processing method of the pacifier is the same as that of Example 1, the only difference is that when the baffle 2 and the upper cover 4 in step d, the decorative part 5 and the upper cover 4 in step e are ultrasonically welded, the delay time of the ultrasonic welding process is adopted The welding time is 1.4s, the welding time is 0.8s, the curing time is 1.3s, and the working pressure is 10KPA.

Abstract

The invention discloses a method for processing a pacifier. The pacifier comprises a pacifier head, a baffle and an upper cover. The method for processing the pacifier comprises the following steps of a, performing injection molding on the pacifier head and the baffle respectively by using an injection mold; b, performing secondary injection molding on the upper cover by using the injection mold; c, mounting the pacifier head after injection molding in the step a and the baffle in the step a in a matched way; d, mounting the upper cover in the step b and the pacifier head and the baffle in the step c in the matched way, and sealing the pacifier head with the upper cover and the baffle; e, ultrasonically welding the baffle with the upper cover in the step d. The method disclosed by the invention has the characteristics that safety in use is safe, sanitary and convenient, and shape us diverse.

Description

technical field [0001] The invention belongs to a processing method of a pacifier for babies, in particular to a processing method of a pacifier. Background technique [0002] In the processing methods of pacifiers currently on the market, the baffle and the upper cover are bonded with glue or dehydrated. When using dehydration bonding, the bonding surface is directly on the baffle and the upper cover, which is easy to cause the pacifier to be squeezed and deformed, the appearance is not beautiful, and the processing is difficult; while using the glue bonding process, there will inevitably be some glue residue On the pacifier, it will affect the health of the child, and at the same time, it is prone to weak bonding. Moreover, when the material PP plastic (polypropylene) is used for secondary injection molding, its performance is unstable, and poor welding is likely to occur, which affects the appearance and safety of use. Contents of the invention [0003] The purpose of...
