Description

Technical Field

[0001] The utility model relates to the field of die-cutting blade replacement mechanisms, in particular to a die-cutting blade replacement mechanism for a film die-cutting machine. Background Art

[0002] Die-cutting machine is also called die-cutting machine, cutting machine, CNC punching machine, mainly used for die-cutting (full cutting, half cutting), creasing and hot stamping, laminating, automatic waste discharge of some corresponding non-metallic materials, self-adhesive, EVA, double-sided adhesive, electronics, mobile phone pads, etc. Die-cutting machine uses steel knife, hardware mold, steel wire (or template carved from steel plate), and applies a certain pressure through the stamping plate to roll and cut the printed product or cardboard into a certain shape. It is an important equipment for post-printing packaging processing and molding. Film die-cutting machine is a type of die-cutting machine, which is used to roll and cut some thin plates or film materials into specific shapes. It is widely used in industrial production for the production of PE film, double-sided adhesive, non-woven fabrics, corrugated cardboard and other products.

[0003] The die-cutting knife of a film die-cutting machine sometimes needs to be replaced during use. Most of the existing die-cutting knives are fixed by bolts. Although the effect of stable fixation is achieved, it also brings the disadvantages of difficult installation and disassembly, resulting in inconvenience in replacement. Therefore, the utility model provides a die-cutting knife replacement mechanism for a film die-cutting machine. Utility Model Content

[0004] The purpose of the utility model is to provide a die-cutting blade replacement mechanism for a film die-cutting machine, so as to solve the problem that the existing die-cutting blades proposed in the above background technology are mostly fixed by bolts, which achieves the effect of stable fixation but also brings about the problem of difficulty in installation and disassembly, resulting in inconvenience in replacement.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a die-cutting knife replacement mechanism for a film die-cutting machine, comprising a knife fixing seat located in the film die-cutting machine, the knife fixing seat being equipped with a die-cutting knife, the die-cutting knife comprising a knife handle and a knife body, the knife handle being detachably connected to the knife body, the knife handle being provided with protrusions on both the front and rear sides, the protrusions on the front and rear sides being staggered, a slot being provided in the knife fixing seat, the knife handle being inserted into the slot, the length of the slot being greater than the length of the knife handle, a socket being provided on the lower side of the slot that matches the protrusion, a card slot being provided on the upper side of the slot, the card slot being connected with the socket, the card slot and the protrusion having the same height, a left card slot being provided at the left end of the slot, the left end of the knife handle being inserted into the left card slot, a sliding block being slidably connected to the right side of the slot, a cylinder being connected to the right end of the knife fixing seat by bolts, and the telescopic end of the cylinder being connected to the sliding block.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1) In the utility model, during the installation of the die-cutting knife, the knife handle is inserted into the slot along the socket. After reaching the top of the slot, the knife handle is moved to the left by a certain distance so that the protrusion enters the slot, so that the socket and the protrusion are misaligned to prevent the knife handle from falling. Then, the cylinder drives the sliding block to move left, pushes the knife handle to the left, and inserts the left end of the knife handle into the left slot, so that the die-cutting knife is stably fixed. When removing the die-cutting knife, the cylinder drives the sliding block to move right so that the knife handle can move in the slot, and then the die-cutting knife can be pulled out from the socket. The die-cutting knife can be stably fixed, and the installation and removal are relatively convenient, and it is easy to replace.

[0014] 2) The die-cutting knife consists of a knife handle and a knife body, which are fixed in a detachable connection. When the knife body is damaged, the knife body can be replaced separately;

[0015] 3) Through the setting of the ejector bolt, when the cylinder drives the sliding block to move right, so that the tool handle can move in the slot, it may be difficult to move the tool handle due to the previous tight fixation. By turning the ejector bolt, the ejector bolt can drive the tool handle to move right, which is easy to disassemble. BRIEF DESCRIPTION OF THE DRAWINGS
