Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to a cutting device for producing heating film. Background Technology

[0002] Heating film is a thin-film product that converts electrical energy into heat energy to provide heating or insulation. Its production involves multiple processing steps, and it is ultimately cut to specific sizes according to actual application needs before being released to the market. With its characteristics of uniform heating, low energy consumption, and easy installation, this product is widely used in building heating, home appliance insulation, and automotive seat heating.

[0003] Currently, cutting equipment used in the production of heating film typically includes a frame, a conveying mechanism, a cutting mechanism, and a control mechanism. The conveying mechanism usually consists of motor-driven conveying rollers that continuously transport the heating film roll to be cut forward through the rotation of the rollers. The cutting mechanism generally includes a blade holder and blades mounted on the blade holder. The blade holder is driven by a cylinder or servo motor to move up and down reciprocatingly. When the heating film is conveyed to the set position, the blades fall to complete the cutting action. The control mechanism detects the conveying length of the heating film through sensors and coordinates the working rhythm of the conveying mechanism and the cutting mechanism to ensure the accuracy of the cutting dimensions.

[0004] In existing technologies, the cutting width of cutting devices used in heating film production is mostly fixed, and the installation position of the blades is fixed relative to the frame, making it impossible to quickly adjust according to the width requirements of heating films of different specifications. When it is necessary to cut heating films of different widths, operators need to disassemble the blades on the blade holder, remeasure and reposition the installation position, and then perform fixed adjustments. This process is not only time-consuming but also prone to inconsistent cutting widths due to human error, seriously affecting production efficiency and product quality, and making it difficult to meet diverse production needs. Therefore, a cutting device for heating film production is proposed to solve the above problems. Utility Model Content

[0039] When replacing the fixed blade 20, first press the buttons 19 on both sides of the blade holder 18. The limiting plate 21 at one end of the button 19 pushes the locking block 23. At this time, the second spring 22 is compressed and the locking block 23 is disengaged from the groove on the inner wall of the blade holder 18. The blade holder 18 and the fixed blade 20 can then be removed from the connecting rod 17 for replacement. During installation, simply push the blade holder 18 back. Under the reaction force of the second spring 22, the connecting rod 17 and the blade holder 18 re-engage, achieving the purpose of easy replacement of the fixed blade 20. This solves the problems of the traditional blade replacement process being cumbersome, time-consuming, and requiring high operator skills, which can easily affect production progress due to untimely replacement.
