[0035] Further, as shown in Figure 3As shown, the mounting frame 1 top is fixedly provided with two second electric telescopic rods 4, and the top of the two second electric telescopic rods 4 is fixedly connected with a supporting plate 41, and the top of the supporting plate 41 is uniformly provided with two second grooves 42.

[0036] When the carrier tape 101 is processed, the carrier tape 101 needs to be supported, and the supporting plate 41 is arranged at the bottom of the carrier tape 101 to process the carrier tape 101, so as to reduce the friction time between the supporting plate 41 and the carrier tape 101 and reduce the damage of the supporting plate 41 to the carrier tape 101.

[0037] Further, as shown in the figure, Figure 4 The mounting frame 1 top is fixedly provided with two side plates 5, and two limiting blocks 52 are fixedly installed on one side of the two side plates 5, respectively, and the top of the limiting block 52 is provided with a limiting groove 521, and the bidirectional threaded rod 54 is rotatably installed in the limiting groove 521, and the sliding block 53 is slidably installed in the limiting groove 521, and one end of the sliding block 53 penetrates through the side plate 5 and is fixedly connected to one side of the synchronous belt pulley set 51.

[0039] Further, as shown in the figure, Figure 5 The mounting frame 1 top is fixedly provided with two air outlet pipes 6, and a plurality of heating rods 61 are fixedly installed in the inner cavity of one of the air outlet pipes 6.

[0040] The air outlet pipe 6 bottom is rotatably provided with two pulleys 62, and the pulley 62 top is fixedly connected with a fan blade 63, and the four pulleys 62 are driven by a belt 64, and the bottom of one of the pulleys 62 is fixedly connected with a second motor 65, and the second motor 65 is fixedly installed on one side of the mounting frame 1.

[0041] In use, to facilitate the processing of the carrier belt 101, the output shaft of the second motor 65 drives the pulley 62 to rotate. Through the drive of the fan blade 63, all four pulleys 62 begin to rotate, and the heating rod 61 begins to heat up. The rotation of the fan blade 63 driven by the pulley 62 blows the air at the bottom of the air outlet 6 to the top of the air outlet 6 for release. During this process, the flowing air carries the heat generated by the heating rod 61 and blows it toward the carrier belt 101, which can achieve the purpose of heating the carrier belt 101. After the carrier belt 101 is processed, in order to avoid the residual heat on the carrier belt 101 affecting the quality of the carrier belt 101, the airflow blown out through another air outlet 6 can dissipate heat from the carrier belt 101.

[0042] Working principle: First, the carrier belt 101 is passed between the first roller 25 and the second roller 31. The height of the top plate 22 is adjusted by the extension and retraction of the first electric telescopic rod 2. During this process, the top plate 22 drives the damper 23 and the first roller 25 to move. The first roller 25 will be at the top of the carrier belt 101, which can limit the carrier belt 101 when facing carrier belts of different thicknesses. The four dampers 23 can prevent the extension and retraction force of the first electric telescopic rod 2 from directly acting on the carrier belt 101 and causing damage to the carrier belt 101. The output shaft of the second motor 65 drives the pulley 62 to rotate. The pulley 62 further drives the fan blade 63 to rotate, which can blow the heat generated by the heating rod 61 to the carrier belt 101, thus facilitating the processing of the carrier belt 101. The air blown out through another air outlet 6 can cool the carrier belt 101 and prevent the residual heat after processing from damaging the carrier belt 101.

[0043] Adjusting the height of the support plate 41 using two second electric telescopic rods 4 can reduce the friction time between the support plate 41 and the carrier belt 101. During processing, the waste material on the carrier belt 101 falls through the second groove 42. During use, the width of the carrier belt 101 is detected by the length detector 32. Then, the output shaft of the first motor 56 drives the synchronous pulley group 51 to rotate. The synchronous pulley group 51 drives the bidirectional threaded rod 54 to rotate, thereby causing the slider 53 to bring the limiting roller 55 close to the side of the carrier belt 101 to limit the carrier belt 101 and prevent the carrier belt 101 from shifting during processing.

[0044] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
