[0004] In existing technologies, the device trims the film edges using a cutting structure. However, ordinary cutting tools become dull over time, resulting in uneven and rough edges, which leads to poor sensory quality of the finished product. To address this issue, a high-temperature cutting tool is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature edge trimming cutter that can maintain the high temperature of the blade during the trimming process to ensure a smooth and even cut edge of the film, and effectively avoids the problem of rough film edges caused by blade wear.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-temperature trimming cutter, comprising a crossbar, on which a cutting assembly is clamped and installed, the cutting assembly comprising a clamping assembly and a blade holder, the blade holder being fixedly connected to the clamping assembly, and the clamping assembly being clamped and installed on the crossbar;

[0008] The heating assembly includes a control switch, and a resistance heater is mounted on the bottom of the control switch via a second connecting wire. The resistance heater is in contact with the cutting blade but is not fixedly connected to it.

[0009] Preferably, the clamping assembly includes an upper clamp and a lower clamp, the rear ends of which are rotatably connected by a pivot, and the upper clamp has a through hole at its front end. This rotatable connection between the upper and lower clamps provides flexibility to the clamping assembly, allowing it to be easily adjusted to accommodate crossbars of different sizes.

[0010] The through hole design at the front end of the upper clamp allows the adjusting screw to pass through, enabling the wing nut to be quickly installed and adjusted, thus improving the ease of operation.

[0011] Preferably, the lower clamp has a slotted front end and an adjusting screw is rotatably mounted on it via a pivot. The top of the adjusting screw passes through a through hole on the upper clamp and is threaded with a wing nut. The slotted front end of the lower clamp and the design of the adjusting screw allow for precise adjustment of the position of the clamping assembly, ensuring accurate alignment of the cutting blade.

[0012] The adjusting screw and wing nut, which are mounted by rotating the shaft, provide a stable fixing mechanism to ensure that the cutting blade remains stable during the cutting process.

[0015] Preferably, the control switch is fixedly installed on one side of the tool holder. A first connecting wire is located at the rear of the control switch, through which the control switch is electrically connected to an external power source. A second connecting wire is located at the bottom of the control switch, through which the control switch is electrically connected to the resistance heater. This design, with the control switch fixedly installed on one side of the tool holder, reduces wiring clutter and improves operational safety and equipment reliability.

[0016] The design of the first and second connecting lines makes the connection between the control switch and the external power supply and resistance heater simple and direct, facilitating installation and maintenance.

[0017] Preferably, the second connecting wire adopts a spring-loaded structure design and its outer wall is covered with a TPE outer sheath, and the resistance heater is in close contact with the outer wall of the cutting blade through the second connecting wire. In this design, the spring-loaded structure of the second connecting wire enhances its durability, while the TPE outer sheath provides additional protection against wear and damage.

[0018] The design of the resistance heater, with its second connecting wire closely attached to the outer wall of the cutting blade, ensures efficient heat conduction between the resistance heater and the cutting blade, thereby improving heating efficiency and cutting quality.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] The clamping assembly in this invention consists of an upper clamp and a lower clamp, connected by a rotating shaft, providing flexible adjustment capabilities to accommodate crossbars of different sizes.

When the control switch is activated, the resistance heater starts working, and the generated heat is directly transferred to the cutting blade. This design ensures that the blade maintains a high temperature during the cutting process, causing the film edge to melt during cutting, thus forming a smooth cut and avoiding edge roughness caused by blade wear. In summary, this high-temperature edge trimming cutter, through its precise structural design and efficient heating mechanism, ensures a high-temperature state of the blade during the cutting process, thereby effectively improving the cutting quality and avoiding the problem of rough edges caused by blade wear.

[0027] Example 1

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one embodiment of the present invention is provided: a high-temperature edge trimming cutter, including a crossbar 2, on which a cutting component 1 is clamped and installed. The cutting component 1 includes a clamping component 11 and a blade holder 12.

[0031] Specifically, the clamping assembly 11 consists of an upper clamp 111 and a lower clamp 112, which are rotatably connected by a pivot, thus providing flexible adjustment capabilities to accommodate crossbars 2 of different sizes. This design allows the clamping assembly 11 to be easily fixed to the crossbar 2, ensuring stability during the cutting process. The blade holder 12 is fixedly connected to the clamping assembly 11 and has a reserved slot 121 in the middle of its bottom for quick replacement and adjustment of the cutting blade 14. A heating assembly 13 is installed on one side of the blade holder 12, ensuring that the resistance heater 133 is in close contact with the outer wall of the cutting blade 14, thereby achieving efficient heat conduction. The heating assembly 13 includes a control switch 131 and a resistance heater 133. The control switch 131 is connected to an external power source via a first connecting line 132, and a second connecting line 134 is connected to the resistance heater 133. The resistance heater 133 is in contact with the cutting blade 14 but not fixedly connected, ensuring that the temperature can be controlled as needed during the heating process. When the control switch 131 is activated, the resistance heater 133 starts to work, and the heat generated is directly transferred to the cutting blade 14. This design ensures that the blade maintains a high temperature during the cutting process, causing the film edge to melt and form a smooth, even cut, thus avoiding the rough edge problem caused by blade wear. In summary, this high-temperature edge trimming blade, through its precise structural design and efficient heating mechanism, ensures a high-temperature blade during the cutting process, effectively improving cutting quality and preventing rough edges caused by blade wear.

[0032] Example 2

[0033] To facilitate adjustment of the cutting blade's mounting position, such as Figure 1 and Figure 4 As shown, in this embodiment, the clamping assembly 11 includes an upper clamp 111 and a lower clamp 112. The rear ends of the upper clamp 111 and the lower clamp 112 are rotatably connected by a pivot. The upper end of the upper clamp 111 has a through hole. The design of the upper clamp 111 and the lower clamp 112 being rotatably connected by a pivot provides flexibility to the clamping assembly 11, allowing it to be easily adjusted to accommodate crossbars 2 of different sizes.

[0034] The through hole design at the front end of the upper clamp 111 allows the adjusting screw 1121 to pass through, enabling the wing nut 1122 to be quickly installed and adjusted, thus improving the ease of operation.

[0035] Furthermore, the lower clamp 112 has a slot at its front end and an adjusting screw 1121 is rotatably mounted on it via a pivot. The top of the adjusting screw 1121 passes through a through hole on the upper clamp 111 and is threaded with a wing nut 1122. The slot at the front end of the lower clamp 112 and the design of the adjusting screw 1121 allow for precise adjustment of the position of the clamping assembly 11, ensuring accurate alignment of the cutting blade 14.

[0036] The adjusting screw 1121 and wing nut 1122, which are mounted by rotating the shaft, provide a stable fixing mechanism to ensure that the cutting blade 14 remains stable during the cutting process.

[0037] Example 3

[0038] To achieve rapid temperature control of the cutting blade, such as Figure 2 and Figure 3 As shown, in this embodiment, a reserved groove 121 is provided in the middle of the bottom of the cutter holder 12, and a screw hole is provided on one side of the cutter holder 12, on which a positioning bolt 122 is threaded. One end of the positioning bolt 122 passes through the screw hole and contacts the cutting blade 14 but is not fixedly connected. The reserved groove 121 at the bottom of the cutter holder 12 allows for quick replacement and adjustment of the cutting blade 14, improving the adaptability and ease of maintenance of the equipment.

[0039] The design of the positioning bolt 122 allows the cutting blade 14 to contact the blade holder 12 but not be fixedly connected, providing quick replacement of the cutting blade 14 to adapt to different cutting needs.

[0040] Furthermore, the control switch 131 is fixedly installed on one side of the tool holder 12. A first connecting wire 132 is provided at the rear end of the control switch 131, through which the control switch 131 is electrically connected to an external power source. A second connecting wire 134 is provided at the bottom of the control switch 131, through which the control switch 131 is electrically connected to the resistance heater 133. In this design, the control switch 131 is fixedly installed on one side of the tool holder 12, reducing wiring clutter and improving operational safety and equipment reliability.

[0041] The design of the first connecting line 132 and the second connecting line 134 makes the connection between the control switch 131 and the external power supply and the resistance heater 133 simple and direct, and facilitates installation and maintenance.

[0042] Furthermore, the second connecting line 134 adopts a spring-loaded structure design and is covered with a TPE outer sheath.

The spring-loaded structure design of the second connecting line 134 enhances its durability, while the TPE outer sheath provides additional protection against wear and damage.

[0043] The design of the resistance heater 133, which is closely attached to the outer wall of the cutting blade 14 by means of the second connecting line 134, ensures efficient heat conduction between the resistance heater 133 and the cutting blade 14, thereby improving heating efficiency and cutting quality.

[0044] In use, the control switch 131 is fixedly installed on one side of the blade holder 12, and the control switch 131 is electrically connected to an external power source via the first connecting line 132. The cutting blade 14 is placed in the reserved slot 121 at the bottom of the blade holder 12 and fixed with the positioning bolt 122. By adjusting the engagement of the screw 1121 and the wing nut 1122, the clamping assembly 11 is moved to a suitable position along the crossbar 2 and fixed. The control switch 131 is turned on to start the resistance heater 133. The second connecting line 134 adopts a spring structure design, which maintains contact with the cutting blade 14 through its elasticity. The resistance heater 133 heats the cutting blade 14 through heat conduction. When the cutting blade 14 reaches a suitable high temperature, the high temperature melts the edge of the film and forms a smooth cut after cutting. If necessary, a control device can be added, and the temperature and cutting speed of the resistance heater 133 can be adjusted in a timely manner according to the material of the film and the desired cutting effect to maintain the best cutting effect. After cutting is complete, turn off the control switch 131 to disconnect the power supply, allow the cutting blade 14 to cool naturally or use an appropriate cooling method to cool it down, and clean the cutting blade 14 and the blade holder to prepare for the next use.
