A cutting blade wheel is mounted at the bottom of the cutting head body, and a sliding seat that matches a guide rail is installed within the mounting groove. This allows the cutting head body to slide along the guide rail, and the cutting blade wheel at the bottom of the cutting head body cuts the tile. However, the cutting head body structure of existing tile cutters is complex. Furthermore, unevenness in the tile surface can cause sliding obstruction or poor stability when the cutting head body slides along the guide rail, affecting the cutting effect and quality. Utility Model Content

[0005] Each sliding support is equipped with at least two track bearings, and all track bearings are on the same horizontal plane. The tension bearing is located between all track bearings, and the position of the tension bearing on the sliding support is lower than that of the track bearings.

[0006] There are two track bearings on each side of the sliding support, and the tension bearing is located between the two track bearings.

[0007] The sliding support seat has an elliptical through hole that runs through both sides of the sliding support seat. A rotating rod passes through the elliptical through hole, and the two ends of the rotating rod pass out of the elliptical through hole and are fixed to the inner ring of the tension bearing. The rotating rod can move up and down along the major axis of the elliptical through hole. The top of the sliding support has a threaded hole that communicates with the elliptical through hole, and a tensioning bolt is also provided. The tensioning bolt is screwed into the threaded hole, and a spring is provided between the end of the tensioning bolt placed in the threaded hole and the rotating rod.

[0008] The sliding support is inverted T-shaped and includes a base plate and a support plate. The support plate is fixed perpendicularly to the base plate.

[0011] A novel tile cutting head sliding device mounting structure includes the novel tile cutting head sliding device described above, and also includes a guide rail, wherein the novel tile cutting head sliding device is mounted on the guide rail; The guide rail is provided with grooves with bottom openings that extend along the length of the guide rail. The top of the slide is provided with slots on both sides, and a columnar rail is installed in the slot. Part of the columnar rail is located in the slot and part of it extends out of the slot and is located in the slide. Tension bearing rails are provided on both sides of the bottom surface of the chute facing the top surface of the chute; The mounting groove on the main body of the cutting head is fitted onto the guide rail, and the sliding support seat is placed in the slide groove of the guide rail. The track bearings on both sides of the sliding support seat abut against the column-shaped track on both sides of the top of the slide groove; the tension bearings on both sides of the sliding support seat abut against the tension bearing track on both sides of the bottom of the slide groove. Meanwhile, an annular groove is provided on the track bearing, which abuts against the bottom surface of the column track to prevent the track bearing from detaching from the length direction of the column track when it slides on the column track.

[0017] Preferably, the sliding support is in the shape of an inverted T, including a base plate and a support plate, with the base plate fixed to the side wall of the mounting groove by bolts.

[0018] When used with a guide rail, the guide rail has a groove, and there are retaining grooves on both sides of the top of the groove, in which columnar rails are installed. Tension bearing rails are set on both sides of the bottom of the groove.

[0019] The track bearing abuts against the cylindrical track, and the tension bearing abuts against the tension bearing track. Additionally, the track bearing has an annular groove to prevent it from slipping off the cylindrical track.

[0020] In use, when the tension bearing moves to a location with protruding particles or impurities on its track, the tension bearing moves upward under the action of these particles, causing the rotating rod to press the spring upward along the elliptical perforation. When the tension bearing moves away from the protruding particles or impurities, the spring releases pressure, pressing the rotating rod downward. The downward movement of the rotating rod keeps the tension bearing in constant contact with its track, thus enabling the device to adapt to uneven tile surfaces and achieve stable cutting.

[0021] In summary, this utility model provides a novel sliding device for a ceramic tile cutting head and its installation structure. Through the design of a sliding support base, a track bearing, and a tension bearing, the structure of the cutting head body is simplified; it can automatically adapt to the unevenness of the ceramic tile surface, ensuring the stability of the cutting process; thus, it has great market application and promotion value.
