[0033] Specifically, it should be noted that in this embodiment, there are a total of four support columns 101.

[0034] Specifically, it should be noted that in this embodiment, two sets of pressing wheels 2 are arranged side by side.

[0035] In order to improve the positioning accuracy and prevent the card strip 3 from shifting forward and backward during the conveying and guiding process, a plurality of guide grooves 5 are provided at the circumferences of the pressing wheels 2. In this embodiment, each pressing wheel 2 is provided with 2 guide grooves 5 of the same width for the width of the card strip 3, and an elastic sleeve 501 of a corresponding size is sleeved outside each guide groove 5, so as to make the card strip 3 fit more closely with the pressing wheel 2 during the conveying and guiding process.

[0047] Working principle: When the processing production line of the automotive seat strip 3 is started, first place the strip 3 on the guide groove 5, and then start the external control system of the conveying and guiding mechanism. At this time, the external control system controls the rotation of the lead screw 9 through the control motor 8, and the nut 10 drives the cross connecting rod 402 to drive the first pressing wheel 201 to move up and down until the first pressing wheel 201 reaches the corresponding position.

[0048] In summary of the above embodiments, through the conveying and guiding mechanism of the pressing wheel 2 with multiple guide grooves and the lead screw and nut assembly, the present utility model can achieve the purpose of higher processing stability and faster processing efficiency during the processing of automotive seat strips, and can effectively control and adjust the distance between the upper and lower pressing wheels 2 according to the actual situation to adapt to strips of different thicknesses.
