Description

Planar In-Mold Forming Label Insertion Mechanism

technical field

The invention relates to a planar in-mold forming label insertion mechanism, in particular to such a planar in-mold forming label insertion mechanism, which uses a mechanical arm to drive a fixing seat, and then uses a finished product located on one side of the fixing seat to take out The device takes out the plastic product from the mold, and then draws a label from the label pushing device by taking or setting the label holder, and then puts the label into the cavity of the mold. After the plastic product is formed, it can be made into an in-mold sticker. Standard one-piece plastic product.

Background technique

At present, there are various plastic products made of plastic materials on the market. In order to make the plastic products have a better decorative effect, during the injection or extrusion or vacuum forming process of the plastic products, the label is placed in the molding mold in advance, and the mold is ready to be formed. After the plastic product in the mold is formed, the in-mold label forming method that can combine the label with the plastic product has gradually been extensively researched and discussed by plastic molding manufacturers. In the manufacturing process of the aforementioned in-mold label forming method, the pre-printed label is first placed into the forming mold. After the plastic product is injected or extruded or vacuum formed in the forming mold, the label and the plastic product can be made. combined.

And to put the label into the mold, in addition to the manual insertion method, it is to use mechanical equipment. Therefore, there is the well-known patent case of Taiwan Announcement No. 538956 "Suction transfer unit of plastic film labeling machine", which is provided with a vacuum suction channel for sucking labels in a body, and the vacuum suction channel utilizes a vacuum generator Vacuum is generated, and after the main body contacts with the suction tank, the label can be sucked and placed into the molding mold of the plastic product at the same time, so as to complete the action of taking or placing the label.

However, this known case is only aimed at the adsorption of the label. When the label is placed into the forming mold, it may be due to the problem of the vacuum generator or the main body. Product defects and poor yield of finished products.

Here, the inventor of this case also obtained Taiwan Invention Patent No. 177242 "in-mold labeling label insertion mechanism". In this case, the round label is pushed into the forming mold through a pusher In order to achieve the purpose of automation, but in this case, a label slot is set on the pusher to place the label, which is different from the structure of the planar label in this case.

Therefore, the present inventor further researches on the automatic method of in-mold forming of plastic products for planar labels, and invents the present case.
