Description

Technical Field

[0001] The invention relates to the technical field of cosmetic and pharmaceutical packaging, and in particular to a trimming machine for a blowing, filling and sealing integrated machine. Background Art

[0002] Blow-fill-seal three-in-one aseptic filling technology refers to bottle blowing-filling-sealing. Blow-fill-seal is an advanced aseptic processing technology. During the whole process, plastic containers are extruded from polymer particles into molds, and then filling and sealing are completed in a set of continuous processes. It is different from the traditional aseptic operation process in which container molding, preparation, sterilization, filling and sealing are completely independent. Compared with traditional aseptic filling, Blow-fill-seal is an advanced aseptic filling process because the whole process is automated and does not require many workers to operate during the production process. Therefore, using a reasonably configured BFS machine for aseptic filling can achieve a high degree of sterility.

[0003] When the existing blow-fill-seal equipment is used for production and packaging, there are a lot of waste edges around the formed plastic bottles, which must be removed with the help of a special trimming device during subsequent use. At present, most of the trimming machines on the domestic market adopt horizontal punching, which requires multiple clamps to transport the bottle embryo to the trimming position. There are problems such as poor positioning accuracy and long production debugging time. Therefore, a trimming machine for a blow-fill-seal integrated machine is needed to avoid the problem of poor positioning accuracy caused by the alternation and transportation of multiple clamps, reduce personnel intervention, avoid cross contamination, shorten production adjustment time, and improve production efficiency.

[0032] Working principle: in the initial state, the uppermost mold opening cylinder 131 of the punching mechanism 13 is retracted. After the preform enters from the feed port of the trimming device 1, the uppermost mold opening cylinder 131 of the punching mechanism 13 extends to lower the feeding mechanism 12 so that the clamping claw 122 hooks the preform. Under the action of the feeding cylinder 121 of the feeding mechanism 12, the clamping claw 122 is pushed to make the preform enter under the finished product punching die of the punching mechanism 13. The upper and lower pressing plates of the finished product punching die of the punching mechanism 13 are respectively closed under the action of the upper pressing plate cylinder 132 and the lower pressing plate cylinder 134 to prevent the preform from moving. Next, the punch in the middle of the finished trimming die separates the finished product from the preform under the push of the punching cylinder 133. After the punching is completed, the punch retracts, and the upper and lower pressure plates of the mold are opened. Then, under the action of the feeding mechanism 12, the remaining waste edges that have just been punched continue to be transported to the waste cutting position, and at the same time, a new plate of material is transported to the bottom of the finished product trimming mold. Immediately after the finished product punching mold is punching, the waste cutting tool cuts the waste edges from the bottle embryo under the action of the waste cutting cylinder 135. The cut waste edges are moved from the first chute of the product transfer mechanism 14 to the waste conveyor 3, and the cut finished products fall from the second chute of the product transfer mechanism 14 onto the receiving plate 143. The product transfer mechanism 14 retracts through the transfer cylinder 142 to move the product to the finished product conveyor belt. At this time, one cycle of trimming work is completed.
