[0031] According to the first aspect of the present invention, a main roller and shaft connection structure is provided, such as Figure 1 and Figure 2As shown, the main roller and the shaft connection structure is used for a square opening machine, and the main roller and the shaft connection structure includes a shaft body 1 and a main shaft body 2.

[0032] In the following description, reference will be made to Figure 1 and Figure 2 The detailed structures of the shaft body 1 and the main shaft body 2 of the main roller and shaft connection structure are described in detail.

[0033] like Figure 1 and Figure 2 As shown in the embodiment, the main roller and shaft connection structure includes a shaft body 1 and a main shaft body 2 that are connected to each other. One end of the shaft body 1 is connected to a drive motor via a coupling to enable the shaft body 1 to rotate, and the other end of the shaft body 1 is connected to the main shaft body 2 to drive the main shaft body 2 to rotate. The first end of the shaft body 1 is provided with a semicircular groove, and the interior of the semicircular groove is provided with a connecting block 102. The connecting block 102 can be formed into a roughly U-shaped structure. The U-shaped structure facilitates docking and sliding, so that the main shaft body 2 can be repositioned. The repositioning here refers to the need to replace the wire groove on the disk (not shown) according to wear during operation of the square cutting machine. In this case, the position of the main shaft body 2 needs to be changed to drive the repositioning of the wire groove. The first end of the main shaft body 2 is provided with a connecting groove 202. The connecting groove 202 matches the connecting block 102. Matching here refers to matching in shape and size. The connecting groove 202 can also be formed into a U-shaped structure to form a U-shaped structure that matches the connecting block 102. In the embodiment, the connecting block 102 is inserted into the connecting groove 202 . Thus, the first end of the shaft body 1 and the first end of the main shaft body 2 are connected to each other through the connecting block 102 and the connecting groove 202 .

[0034] To sum up, the main roller and the axis connection structure can quickly and accurately connect the axis body 1 and the main shaft body 2 through the connecting block 102 of the axis body 1 and the connecting groove 202 of the main shaft body 2, and the connection process is simple and easy to operate. The axis body 1 and the main shaft body 2 can be connected in place and compactly, avoiding the main shaft body 2 from jumping or the screws of the main shaft body 2 from breaking, and also avoiding the diamond wire breakage or line marks on the crystal rod surface during the cutting process of the square cutting machine.

[0035] Preferably, if Figure 1 and Figure 2 As shown, in the embodiment, the first end of the shaft body 1 and the first end of the main shaft body 2 are slidably connected via a connecting block 102 and a connecting groove 202. To facilitate replacement of the wire duct, the connecting block 102 and the connecting groove 202 both adopt a U-shaped structure, which enables sliding at the connection between the first end of the shaft body 1 and the first end of the main shaft body 2.

[0036] Preferably, if Figure 1As shown, in the embodiment, the first end of the shaft body 1 is formed into a fan ring structure, which includes an inner wall and an outer wall facing each other, the inner wall is formed into a semicircular groove, and the connecting block 102 is arranged on the inner wall. Figure 1 The ring portion 101 includes an inner ring wall 103 and an outer ring wall 104, both of which are arranged in opposite directions. The inner ring wall 103 and the outer ring wall 104 are both formed in an arc shape. The connecting block 102 is provided on the inner ring wall 103. The first end of the shaft body 1, formed into a ring-shaped structure, facilitates both docking and sliding.

[0037] Preferably, if Figure 1 and Figure 2 As shown, in the embodiment, the first end of the main shaft body 2 is formed into a cylindrical structure, and the connecting groove 202 is opened on the outer wall of the cylindrical structure, and the connecting groove 202 is opened along the axial direction of the cylindrical structure. Figure 2 The cylindrical end 201 has a diameter smaller than that of the main shaft body 2 to facilitate docking. A connecting groove 202 is defined along the axis of the cylindrical end 201 on its outer wall. When the first end of the core body 1 and the first end of the main shaft body 2 are docked, the outer wall of the cylindrical end 201 abuts against the inner wall 103 of the sector ring 101.

[0038] Preferably, in an embodiment, the main roller and shaft connection structure further includes a plurality of gaskets, each of which is sequentially sleeved onto the first end of the main shaft body 2. The gaskets can be used to change the position of the main shaft body 2. Sleeved onto the cylindrical end 201, the gaskets can be formed into a circular ring structure with a thickness of 1 mm or 2 mm. The specific specifications can be selected based on the different groove spacing of the disk's wire grooves. Whenever the position of the wire groove needs to be changed, the operator can remove a gasket from the cylindrical end 201 and then push the main shaft body 2 closer to the shaft body 1.

[0039] Preferably, if Figure 2 As shown, in an embodiment, the spindle body 2 may further include a roller shaft, which is located in the middle of the spindle body 2. Connecting pieces 203 for mounting a disk are provided at both ends of the roller shaft. The connecting piece 203 may be formed in a disc shape and may have a plurality of connecting holes formed therein. The disk may be connected to the connecting piece 203 through the plurality of connecting holes.

[0040] Preferably, if Figure 2As shown, in the embodiment, the diameter of the cylindrical structure is smaller than the diameter of the roller shaft. The diameter of the cylindrical end 201 is smaller than the diameter of the roller shaft. The smaller diameter of the cylindrical end 201 facilitates docking with the shaft body 1 and position adjustment. The smaller diameter of the cylindrical end 201 also facilitates installation and removal of the gasket.

[0041] Preferably, if Figure 1 and Figure 2 As shown, in the embodiment, the shaft body 1 further includes an abutment portion 105 connected to the first end. When the first end of the shaft body 1 is docked with the first end of the spindle body 2, the first end of the spindle body 2 abuts the abutment portion 105. The abutment portion 105 can serve as a limiting structure for limiting the movement of the spindle body 2.

[0042] Preferably, if Figure 1 and Figure 2 As shown, in the embodiment, the first end of the shaft body 1 abuts against the inner side wall of the first end of the main shaft body 2. The two can be understood as a sleeve connection structure, which can achieve quick connection while enhancing stability.

[0043] The installation process of the main roller and shaft connection structure is as follows: a plurality of gaskets are placed on the first end of the main shaft body 2, i.e., the cylindrical end 201. The specifications of the gaskets can be specifically selected according to the spacing of the wire grooves. Then, the first end of the main shaft body 2 is aligned with the first end of the shaft body 1, and the connecting groove 202 and the connecting block 102 are abutted against each other. When the squarer is in use, if the wire groove needs to be replaced, the operator removes the corresponding gasket and pushes the main shaft body 2 toward the shaft body 1 to replace the wire groove.

[0044] The main roller and the axis connection structure can connect the axis body and the main shaft body. The axis body and the main shaft body can be connected quickly and accurately through the connecting block of the axis body and the connecting groove of the main shaft body. The connection process is simple and easy to operate. The axis body and the main shaft body can be connected in place and compactly, avoiding the main shaft body from jumping or the screws of the main shaft body from breaking, and also avoiding the diamond wire from breaking or the surface marks of the crystal rod during the cutting process of the square cutting machine.

[0045] Furthermore, according to a second aspect of the present invention, a square cutting machine is provided, comprising the main roller and shaft connection structure described above. During use, the main roller and shaft connection structure ensure a tight and stable connection between the shaft body 1 and the main shaft body 2, thereby preventing the main shaft body 2 from bouncing or the screws of the main shaft body 2 from breaking. Furthermore, the square cutting machine avoids diamond wire breakage or surface marks on the ingot during cutting.

[0046] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them.
