Description

[Technical field]

[0001] The invention relates to the technical field of automated manufacturing, in particular to an IMR film scrap removal mechanism. [Background technology]

[0002] IMR, also known as in-mold transfer, is a process in which a texture pattern is printed on a foil film, which is then transported to the mold cavity by a foil feeder, extruded by an injection molding machine, and the pattern texture is transferred to the injection molded part. During this process, the ink layer remains on the product, but the foil film is not attached to the surface. The film is only a carrier in the production process.

[0003] like Figure 1 As shown, the IMR injection molded product 1 has many holes 2, and film chips from the IMR process will remain in the hole area, which needs to be removed to meet customer requirements. The traditional method is to use a sandblasting machine, which can complete the chip removal process by sweeping the surface of the product 1 back and forth with the sandblasting machine (nylon sand with a diameter of 0.2mm sprayed out by the sandblasting machine at high pressure). However, the use of a sandblasting machine requires the loss of sand particles and a large amount of air pressure, so an additional air compressor needs to be opened every day, and after sandblasting, an operator is required to blow sand and an operator to clean the sand mist on the surface, which makes the labor and consumables costs high, and it is difficult to achieve automatic pick-up and placement when multiple products are produced in one machine.

[0004] In view of this, it is necessary to provide an IMR film scrap removal mechanism to solve the above problems. [Summary of the invention]
