[0027] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1 As shown, an embodiment of the utility model provides a conveyor belt roller installation device, which is used to replace the roller 71 on the installation roller 7. The roller 7 includes the roller 71 and a roller shaft 72 that cooperates with the roller gap. The conveyor belt roller installation device includes: a mounting seat 1, a fixed end 2, a movable end 3, a guide rod 4 and a chuck 5.

[0029] Specifically, the mounting seat 1 extends along the axial direction of the roller 7 .

[0030] The fixed end 2 is arranged at one end of the mounting seat 1 , and the fixed end 2 is used to receive one end of the roller 7 .

[0031] The movable end 3 is arranged opposite to the fixed end 2 along the axial direction of the roller 7 , and the movable end 3 is slidably connected to the mounting seat 1 . The movable end 3 is used to receive the other end of the roller 7 .

[0032] The guide rod 4 extends along the axial direction of the roller 7 , one end of the guide rod 4 is fixedly connected to the fixed end 2 , and the other end of the guide rod 4 is slidably connected to the movable end 3 .

[0033] The chuck 5 is sleeved on the guide rod 4 , and the chuck 5 can slide along the guide rod 4 between the fixed end 2 and the movable end 3 . The chuck 5 is a hollow structure, and is used to clamp the roller 71 and fix the position of the roller 71 on the roller shaft 72 .

[0034] Specifically, the chuck 5 includes a large bevel gear, a plurality of small bevel gears, and claws 53 corresponding to the number of small bevel gears. The plurality of small bevel gears mesh with one side of the large bevel gear, and the other side of the large bevel gear has a planar rectangular thread structure, and the plurality of claws 53 with threads are equally mounted on the planar rectangular thread. When the operator rotates the small bevel gear with the help of a tool (e.g., a wrench, etc.), the large bevel gear rotates with it, and then the planar rectangular thread structure is used to drive each claw 53 to approach or disperse toward the center at the same time. Because the pitch of the planar rectangular thread is equal, the movement distance of each claw 53 is equal, so it has the function of automatic centering.

[0035] The applicant has fully considered the problems that arise when installing the roller 71 of the conveyor belt roller installation device, and by using the hollow structure of the chuck 5 to clamp the roller 71, and by using the automatic centering function of the chuck 5, the roller 71 that is in clearance fit with the roller shaft 72 can be guaranteed to be concentric with the roller shaft 72, and the chuck 5 can slide between the fixed end 2 and the movable end 3 along the guide rod 4, so that the chuck 5 can clamp the roller 71 at different positions to fix the roller 71 and the roller shaft 72 on the entire roller 7 concentrically, so that the roller 71 and the roller shaft 72 on the roller 7 can be set concentrically. In addition, the present application improves the applicability of the conveyor belt roller installation device by setting the movable end 3 to slide along the mounting seat 1 to be suitable for rollers 7 of different lengths.

[0036] Furthermore, there are multiple guide rods 4, each guide rod 4 is parallel to each other along the axial direction of the roller 7, and the circumscribed circles of the multiple guide rods 7 are set to be cocentric with the fixed end 2 and the movable end 3, so that the roller 71 and the roller shaft 72 are cocentric.

[0037] Specifically, when the conveyor belt roller installation device is not used, the chuck 5 is placed on the side close to the fixed end 2. When the roller 71 on the roller 7 used to support the conveyor belt is worn and deformed, the operator needs to remove the roller 7 from the conveyor belt. Subsequently, when replacing and installing a new roller 71, the operator first sleeves the new roller 71 on the roller shaft 72, and uses the mobile end 3 to slide along the axial direction of the roller 7, and adjusts the relative position with the fixed end 2 according to the length of the roller 7, so that the roller 7 can be properly installed between the fixed end 2 and the mobile end 3, and then connects the two ends of the roller 7 to the fixed end 2 and the mobile end 3 respectively. When starting to fix the position of the roller 71 on the roller shaft 72, the operator first moves the roller 71 to a preset position (operated according to actual needs), and then adjusts the position of the chuck 5 sleeved on each guide rod 4 on the guide rod 4 to the first roller 71 close to the chuck 5, so that the hollow part of the chuck 5 surrounds the roller 71. Then, the operator adjusts the chuck 5 with the help of a tool (e.g., a wrench, etc.) so that the claws 53 of the chuck 5 clamp the outer circumference of the roller 71 to ensure that the roller 71 is concentric with the roller shaft 72. In addition, a threaded hole is provided on the circumferential surface of the roller 71, and the operator can use screws to fix the roller 71 on the roller shaft 72 to prevent the roller 71 from sliding on the roller shaft 72, thereby installing the roller 71. After completing the installation of one roller 71, the operator can move the chuck 5 along the guide rod 4 to the next roller 71 and repeat the above operation until all the rollers 71 on the entire idler 7 are installed, and then replace and install the roller 71 of the next idler 7.

[0038] In a specific implementation, a slide rail 6 is provided on the upper end surface of the mounting seat 1 , and the movable end 3 can reciprocate along the axial direction of the roller through the slide rail 6 .

[0039] Furthermore, if Figure 2 As shown, one end of the mobile end 3 that is slidably connected to the slide rail 6 is provided with a slider 33 , and the slider 33 is slidably connected inside the slide rail 6 .

[0040] The conveyor belt roller installation device of the utility model is provided with a slide rail 6 on the upper end surface of the installation seat 1 and a slider 33 cooperating with the slide rail 6 is provided on the movable end 3, so that the movable end 3 can slide on the installation seat 1 along the axial direction of the roller 7, thereby changing the position of the movable end 3 along the axial direction of the roller 7 to adapt to rollers 7 of different lengths.

[0041] Furthermore, the mobile end 3 is also provided with a first circular hole 32 corresponding to the position of each guide rod 4, and the other end of each guide rod 4 can pass through the first circular hole 32 corresponding to its position, so that the mobile end 3 is slidably connected to each guide rod 4. The mobile end 3 is provided with the first circular hole 32, which can provide support for each guide rod 4 and enable the mobile end 3 to move along each guide rod 4, so as to improve the applicability of the conveyor belt roller installation device.

[0042] Further, refer to Figure 2 The fixed end 2 and the movable end 3 are both provided with mounting holes 31 on opposite sides thereof, and the mounting holes 31 are used to receive the rollers 7 .

[0043] Specifically, a thread is provided on the inner circumference of the mounting hole 31 , and the roller 7 can be threadedly connected to the fixed end 2 and the movable end 3 .

[0044] The conveyor belt roller installation device of the utility model can be convenient for fixing and supporting the roller 7 on the conveyor belt roller installation device by arranging threaded installation holes 31 on the opposite sides of the fixed end 2 and the movable end 3, so that the operator can install the roller 71.

[0045] Furthermore, if Figure 3 As shown, the chuck 5 is provided with second circular holes 51 corresponding to the positions of the guide rods 4 , and the chuck 5 can reciprocate on the guide rods 5 through the second circular holes 51 .

[0046] The conveyor belt roller installation device of the utility model can be provided with a second circular hole 51 on the chuck 5. When it is necessary to clamp and fix rollers 71 at different positions, it is only necessary to move the chuck 5 along the guide rod 4 to install the rollers 71 at multiple positions on the entire roller 7, thereby reducing the installation time of the rollers and improving the work efficiency of the roller installation.

[0047] Exemplarily, the chuck 5 may be a three-jaw chuck 52 .

[0048] Specifically, the three-jaw chuck 52 can be a manual three-jaw chuck or a power three-jaw chuck. The operator can select the type of three-jaw chuck 52 according to actual needs so as to better clamp the roller 71, thereby ensuring that the roller 71 is concentrically arranged with the roller shaft 72, thereby improving the installation quality of the roller 7.
