[0002] The multi-V belt and the multi-V pulley are common transmission media in the field of automated conveying. Since the mating surfaces of the multi-V belt and the multi-V pulley have protruding trapezoidal wedges, in the prior art, when the multi-V belt is fitted onto the multi-V pulleys at both ends, it is often necessary to manually stretch the multi-V belt so that the multi-V belt can be fitted onto the multi-V pulleys. However, due to the limited elasticity of the multi-V belt, when a shorter multi-V belt ring is used, the multi-V belt can be easily torn, and excessive stretching will seriously affect the life of the multi-V belt, and manual disassembly and assembly is time-consuming and labor-intensive. Summary of the invention

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figure 1 and Figure 2 As shown, the side of the multi-V belt 1 that cooperates with the multi-V belt pulley 2 has a plurality of trapezoidal wedge portions 101 protruding from the surface, and the multi-V belt pulley has grooves that cooperate with the trapezoidal wedge portions. When the multi-V belt 1 is sleeved on the multi-V belt pulleys 2 at both ends, the length of the multi-V belt 1 needs to be pulled to a certain length so that the circumference of the end of the trapezoidal wedge portion 101 is greater than the circumference of the surface of the multi-V belt pulley 2, so that the multi-V belt 1 can be matched and connected with the multi-V belt pulley 2. If the multi-V belt 1 itself is shorter, its elongated length is also correspondingly shorter due to its elastic coefficient, and breakage may occur during the process of cooperation and installation and disassembly of the multi-V belt pulley 2.

[0028] like Figures 3 to 5As shown, the rotating base 3 is shaped like a cylinder, and one end surface of the rotating base 3 is provided with a plug-in base 4 protruding from the rotating base 3. The insert 5 is arranged at the edge of the plug-in base 4 and extends vertically toward the end away from the rotating base 3. The insert 5 is an arc-shaped sheet structure, which can facilitate the insert 5 to enter between the assembled multi-V belt 1 and the multi-V belt pulley 2. The guide 6 is arranged at the edge of the rotating base 3, and the guide 6 extends along the edge of the rotating base 3 perpendicular to the connecting surface of the rotating base 3 and the plug-in base 4. The position of the insert 5 relative to the guide 6 is closer to the axis of the rotating base 3, that is, the horizontal distance between the insert 5 and the axis of the rotating base 3 is smaller than the horizontal distance between the guide 6 and the axis of the rotating base 3, and the distance between the end of the insert 5 away from the plug-in base 4 and the horizontal plane of the rotating base 3 is greater than the distance between the end of the guide 6 away from the rotating base 3 and the horizontal plane of the rotating base 3. The insert 5 and the guide 6 are arranged on the same side relative to the axis of the rotating base 3.

[0029] One side of the guide member 6 has an inclined surface 601 . The inclined surface 601 is in a concave arc shape or a straight inclined surface shape. The inclined surface 601 transitionally connects the edge of the rotating base 3 and the end of the guide member 6 away from the rotating base 3 .

[0030] The circumferential surface of the plug-in base 4 away from the side where the insert 5 is set is a multi-V belt abutment surface 401, and the multi-V belt abutment surface 401 is a semicircular arc surface, and its diameter is approximately the same as or the same as the diameter of the multi-V belt pulley 2. The surface of the plug-in base 4 away from the rotating base 3 has an inwardly recessed shaft end plug-in groove 402, and the shaft end plug-in groove 402 is a hexagonal groove. The shaft end plug-in groove 402 can be matched and connected with the shaft end of the multi-V belt pulley 2, and the shaft end plug-in groove 402 is coaxially arranged with the rotating base 3.

[0031] A handle 8 is provided on a side of the rotating base 3 away from the connecting surface of the plug-in base 4 . The handle can be coaxially arranged with the rotating base 3 . The rotating base 3 can be driven to rotate along its axis by rotating the handle 8 .

[0032] The rotating base 3, the plug-in base 4, the insert 5, the guide 6 and the handle 8 can be separately connected and arranged, or can be integrally formed by a mold.

[0033] like Figure 6 and Figure 7 The figure shows the installation process of the multi-V belt 1 and the multi-V belt pulley 2. Figures 3 to 5, the multi-V belt pulleys 2 are respectively arranged on both sides through the shaft 7, first set the multi-V belt pulley 2 on one side at one end of the multi-V belt 1, and the other end of the multi-V belt 1 is sleeved on the abutting surface of the multi-V belt pulley 2, and the shaft end plugging groove 402 of the plug-in base 4 is matched and connected with the shaft 7 end of the multi-V belt pulley 2 at the other end, the edge of the multi-V belt 1 is abutted with the inclined portion 601 of the guide member 6, and the two ends of the multi-V belt 1 are in a dislocated state. At this time, the rotating base 3 is rotated by the handle 8, and the guide member 6 is rotated and displaced upward, and the inclined portion 601 pushes the multi-V belt 1 to the direction of the multi-V belt pulley 2, and as the guide member 6 rotates, the inclined portion 601 completely pushes the multi-V belt 1 to the surface of the multi-V belt pulley 2, until Figure 7 In the position shown, the insert 5 is located between part of the poly-V belt 1 and the poly-V pulley 2. The handle 8 is pulled out along the length direction of the shaft 7, and the insert 5 is moved out from between the poly-V belt 1 and the poly-V pulley 2. The trapezoidal wedge portion 101 of the poly-V belt 1 is positioned and connected with the poly-V pulley 2 to complete the installation.

[0034] like Figures 8 to 10 The figure shows the disassembly process of the multi-V belt 1 and the multi-V belt pulley 2. Figures 3 to 5 The multi-V belt 1 is sleeved on the multi-V belt pulleys 2 at both ends, and the insert 5 is placed in the opposite direction of the multi-V belt pulleys 2 at both ends. The insert 5 abuts against the circumference of the multi-V belt pulley 2 and does not contact the multi-V belt 1. At this time, the shaft end plug-in groove 402 of the plug-in base 4 is also matched with the corresponding shaft 7 end. Rotate the handle 8 to rotate the rotating base 3, drive the insert 5 to rotate and place it between the multi-V belt 1 and the multi-V belt pulley 2, as shown in FIG. Fig.10 In the position shown, the insert 5 is placed between the trapezoidal wedge portion 101 of the multi-V belt 1 and the circumferential surface of the multi-V pulley 2, so that the multi-V belt 1 and the multi-V pulley 2 are separated. While rotating, the separated part of the multi-V belt 1 can be manually moved out of the multi-V pulley 2 along the length direction of the shaft 7. After rotating 180°, the multi-V belt 1 can be completely moved out of the multi-V pulley 2, and the disassembly is completed.

[0035] By adopting the above-mentioned installation and disassembly method, the entire installation and disassembly process is quick and convenient, and the stretching amount of the multi-V belt 1 can be minimized, thereby preventing damage to the multi-V belt 1 and extending the service life of the multi-V belt 1. The tooling structure disclosed in the present application is simple, saves time and effort, and improves work efficiency.
