A thermal transfer film cutting device with free adjustment function of cutter

Abstract

The invention discloses a heat transfer film cutting device with a function of freely regulating cutters. The heat transfer film cutting device is improved on the basis of a normal cutter drive mechanism, and a plurality of cutter controllable regulating units are designed at the periphery of a cutter mounting frame driven and controlled by a cutter stamping drive air cylinder for replacing an original inflexible cutter mounting mechanism. Each cutter controllable regulating unit comprises a clamping block for fixing one cutter and perpendicular to the cutter, a transverse displacement servo drive device connected with and used for driving the clamping block to transversely move, and a horizontal rotary angle servo drive device connected with and used for driving the transverse displacement servo drive mechanism to rotate, and further comprises a PLC which is used for controlling the transverse displacement servo drive mechanism and the horizontal rotary angle servo drive device to act. By virtue of the cutter controllable regulating units, degree of freedom, in aspects of transverse movement and rotation, of the cutters are realized, so that spacing and angles of the cutters can be freely regulated within a certain range, and therefore, cutting shapes and dimensions of a heat transfer film are increased to adapt to needs, and production cost of enterprises is saved while production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of thermal transfer film production equipment, and in particular relates to a thermal transfer film cutting device with the function of free adjustment of a cutter. Background technique [0002] Thermal transfer production usually refers to the process of cutting the prepared thermal transfer film and laminating it on the substrate. The industry was originally operated manually, but the disadvantages are obvious, such as low efficiency and poor precision. In addition, there are situations where multiple films are stacked and difficult to separate and transferred together, resulting in serious waste of materials. For this reason, through continuous research and development in the industry, production equipment with a high degree of automation has been designed. [0003] A type of automatic equipment for thermal transfer film cutting and pad printing widely used in the industry at present, its structure is us...

AI Technical Summary

Problems solved by technology

[0005]Of course, the above-mentioned mechanism has greatly improved the production efficiency, and the positioning accuracy has been greatly improved compared with manual work. However, in long-term practice, we still find the following problems: due to The cutter around the thermal transfer film in this type of equipment is fixed, and the spacing and angle cannot be adjusted relatively, so it can only be cut to produce a thermal transfer film of a fixed shape (usually rectangular) and size

However, the specific requirements of the market for thermal transfer film are complex and changeable. Obviously, a product with a fixed shape and size cannot well meet the market demand and bring higher benefits to the enterprise.

In order to change the size and shape, the current practice of enterprises is relatively single and clumsy, that is, to disassemble and replace the whole ring cutter

For the cutting of a batch of products, it is necessary to re-open the mold to process and produce the corresponding cutter. For the enterprise, not only the disassembly and replacement is time-consuming and laborious, but also affects the production efficiency, and the production cost is also greatly increased.
