Description

Technical Field

[0001] The utility model relates to the technical field of precision cutting machines, in particular to a precision cutting machine. Background Art

[0002] Foam is a material made of foamed plastic particles, referred to as foam. Foam is divided into PU foam, anti-static foam, conductive foam, EPE, anti-static EPE, CR, EVA, bridged PE, SBR, EPDM, etc. Foam has a series of characteristics such as elasticity, light weight, fast pressure-sensitive fixation, easy to use, easy to bend, ultra-thin volume, reliable performance, etc. Sealing foam can be used to fill the gap between products, buffer, seal, waterproof, eliminate noise between plastic shells such as relay shells, and is easy to operate. In the process of foam production, it is necessary to cut the foam, and a foam precision cutting machine is needed.

[0003] A Chinese patent with patent publication number CN212123503U discloses a precision cutting machine, including a base, on which a material return structure and an automatic feeding structure are installed on the upper wall of the base. The device has a reasonable structure, low cost, and is easy to use. The setting of the automatic feeding structure replaces the original manual feeding of the cutting machine. It only needs to control the forward and reverse rotation of the motor drive end to realize the automatic feeding of the cutting machine, which reduces the labor intensity of the staff. At the same time, the cooperation of the motor and the lead screw increases the accuracy of feeding and improves the cutting accuracy of the cutting machine. After the knife die is cut, the material return structure can automatically eject the material adhered to the knife die to prevent it from affecting the subsequent processing work of the cutting machine. The material can be fixed by the cooperation of the cylinder and the pressure plate to prevent it from positional displacement during cutting.

[0004] Existing precision cutting machines have problems such as foam being easily offset during the cutting process, cutting errors caused by wrinkles affecting cutting accuracy, and the inability to accurately adjust the position of the cutter according to the required cutting length. In order to overcome these disadvantages, the utility model provides a precision cutting machine. Utility Model Content
