Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] refer to figure 1 , figure 2 , the first embodiment of the present invention is a clamping device for unwinding or winding roll material 002; the roll material 002 has a mandrel 001; the clamping device has a mandrel 000, mandrel 000 The upper sleeve is provided with two clamping sleeves 101 arranged opposite to each other. The opposite ends of the two clamping sleeves 101 have steps, and the steps are transitioned by a side wall perpendicular to the axis of the mandrel 000. The side wall is defined as the clamping end. 1012, the two clamping sleeves 101 have clamping ends 1012; the clamping ends 1012 of the two clamping sleeves 101 are clamped on the end face of the core barrel 001; the clamping ends 1012 have a concave portion 1011, and the concave portion 1011 is provided with an elastic The friction part 103, the top of the friction part 103 is ...

Abstract

The invention relates to die-cutting processing technology, in particular to a material clamping device for a coiled material, wherein the coiled material is provided with a core tube; the material clamping device is provided with a core shaft; two oppositely-arranged material clamping sleeves are sleeved on the core shaft; one opposite ends of the two material clamping sleeves are respectively provided with steps which are transitioned through a side wall perpendicular to a core shaft axis; the side wall is defined as a material clamping end; both the material clamping sleeves are provided with a material clamping end; the material clamping ends of the two material clamping sleeves are clamped on the side end face of the core tube; each material clamping end is provided with a concave part; an elastic friction part is arranged inside the concave part; and the top of the friction part is higher than a plane of the material clamping end, so that the friction part can generate friction on the end part of the core tube. The invention provides a difficultly-loosened material clamping device for the coiled material.

Description

technical field [0001] The invention relates to die-cutting processing technology, in particular to a clamping device for roll materials. Background technique [0002] Die-cut products are widely used in automobile manufacturing, electronics industry, especially flat panel display industry, and layered thin materials are everywhere. Insulation materials, shockproof materials, heat-resistant and heat-resistant insulation materials, adhesive products, dust-proof materials, shielding materials, etc. all need to be processed and manufactured by die-cutting technology. [0003] Whether it is rotary die-cutting or flat die-cutting, the die-cutting process involves unwinding and winding. In the prior art, a pair of clamping sleeves with steps are generally used for unwinding and rewinding the roll material, and the roll material is clamped by friction between the side of the step and the end surface of the barrel of the roll material. However, it is very inconvenient to operate b...
