[0042] Example 2

[0043] Based on Example 1, the difference from Example 1 is that:

[0044] like Figure 1 and Figure 3As shown, the first heating element 205 is a heating rod fixedly connected to the first guide roller 202, and a mounting hole 2021 for mounting the first heating element 205 is provided at the axis of the first guide roller 202. The hot stamping part 204 is detachably connected to the first guide roller 202. The second guide roller 203 is connected to a plurality of hot stamping parts 204. The bottom plate 1 is connected to a plurality of printing components 2, and all the first mounting frames 201 are respectively slidably connected to the bottom plate 1, and all the first mounting frames 201 are respectively connected to locking members 3, and the locking members 3 are used to fix the first mounting frames 201 on the bottom plate 1. Figure 2 As shown, the bottom plate 1 is provided with a plurality of connection grooves 101, the locking member 3 penetrates the first mounting frame 201 and is connected to the connection grooves 101, and the distance between adjacent connection grooves 101 is equal to the circumference of the working surface of the first guide roller 202. Figure 1 As shown, it also includes a sliding member 4 vertically slidably connected to the first mounting frame 201, a second driving unit 5 connected to the sliding member 4, the second guide roller 203 is rotatably mounted on the sliding member 4 and is indirectly rotatably connected to the first mounting frame 201, and the second driving unit 5 drives the sliding member 4 to move up and down. It also includes a temperature monitoring component 6 connected to the bottom plate 1 and used to monitor the hot stamping part 204, and the temperature monitoring component 6 is connected to the first heating element 205 by signal.

[0045] The first heating element 205 is a heating rod, which is arranged in the mounting hole 2021 at the axis of the first guide roller 202. The structure is simple, and the first heating element 205 heats evenly. Specifically, the first heating element 205 rotates with the first guide roller 202 during operation and is connected to an external power supply through an electric slip ring. The hot stamping part 204 and the first guide roller 202 are provided with a detachable connection, which is convenient for the replacement of the hot stamping part 204, and then for the replacement of the pattern. The second guide roller 203 is connected with multiple hot stamping parts 204 to improve the hot stamping efficiency, and the multiple hot stamping parts 204 can be respectively provided with different patterns. Further, the multiple hot stamping parts 204 are evenly distributed along the axis of the second guide roller 203.

Furthermore, before operation, the hot stamping parts 204 in each printing component 2 are calibrated, for example, all the hot stamping parts 204 are facing downward, and then all the first guide rollers 202 rotate at the same speed during operation to avoid the hot stamping patterns of the front and rear printing components 2 from being mixed together. The connection grooves 101 are connected to the locking member 3 to increase the fixing effect of the locking member 3. At the same time, the distance between adjacent connection grooves 101 is equal to the circumference of the working surface of the first guide roller 202, which is more convenient for adjusting the position and further avoids the situation where the hot stamping patterns of the front and rear hot stamping components are mixed together. The working surface of the first guide roller 202 is the surface that abuts the wire groove, and the circumference of the working surface of the first guide roller 202 refers to the circumference of the circle with the minimum diameter of the working surface. The second driving unit 5 drives the sliding member 4 to rise and fall, thereby controlling the spacing between the first guide roller 202 and the second guide roller 203, thereby controlling the squeezing force on the wire groove, and can also adapt to the processing of wire grooves of different sizes. The second driving unit 5 can be a telescopic cylinder or a screw connected to the sliding member 4. The screw is threadedly connected to the first mounting frame 201 and the second mounting frame 701. The screw is then connected to a hand wheel or a motor. The hand wheel or the motor drives the screw to rotate forward and backward, thereby driving the sliding member 4 to move up and down. A temperature monitoring component 6 is set to monitor the temperature of the hot stamping part 204, and the temperature monitoring component 6 is connected to the first heating element 205 signal, so that the heating temperature of the first heating element 205 is associated with the temperature of the hot stamping part 204, and the temperature of the hot stamping part 204 can be adjusted more accurately. Since the temperature of the hot stamping part 204 is higher than that of the first guide roller 202 when it is working and is in a rotating state, the temperature monitoring component 6 measures the temperature toward the first guide roller 202 and the hot stamping part 204, and selects the highest temperature as the temperature measurement value of the hot stamping part 204. Specifically, the temperature monitoring component 6 can select a temperature sensor.

[0046] The remaining features and working principles of this embodiment are consistent with those of Embodiment 1.

When working, the base 9 and the upper cover 8 pass through the third guide roller 702 and the fourth guide roller 703 together. Under the rolling action of the third guide roller 702 and the fourth guide roller 703, the base 9 and the upper cover 8 are pressed and assembled together, thereby realizing the automatic assembly of the wire trough. Further, the roller pressing assembly 7 is arranged in front of the printing assembly 2. After the wire trough is roller pressed and assembled, the printing assembly 2 performs pattern hot stamping. The third guide roller 702 abuts against the upper cover 8 in the wire trough, and a second heating element 705 is arranged to heat the third guide roller 702. When the third guide roller 702 abuts against the upper cover 8, the upper cover 8 is preheated before hot stamping. Preheating the upper cover 8 first can reduce the temperature difference between the upper cover 8 and the hot stamping part 204, which is more conducive to hot stamping, and also avoids the situation of wire drawing during hot stamping caused by excessive temperature difference between the hot stamping part 204 and the upper cover 8.

[0051] Further, such as Figure 4 As shown, the temperature monitoring component 6 includes a plurality of temperature sensors, and a temperature sensor is disposed under the rolling component 7 and each printing component 2 .
