DETAILED DESCRIPTION

[0025] like Figure 1-Figure 6 As shown, the utility model provides a technical solution: a conveying roller that is easy to replace, comprising a first roller 1, a second roller 2 is slidably mounted on the inner wall of the first roller 1, a groove 3 is opened on the side wall of the second roller 2, a mounting block 4 is slidably mounted on the inner wall of the groove 3, a return spring 5 is fixed to the side wall of the mounting block 4, and the side of the return spring 5 away from the mounting block 4 is fixed to the inner wall of the groove 3, and the return spring 5 can be set to reset the mounting block 4 by setting the return spring 5, two groups of return springs 5 ​​and mounting blocks 4 are provided, and the two groups of return springs 5 ​​and mounting blocks 4 are symmetrically arranged with the center line of the first roller 1 in the vertical direction as the symmetry axis, and a control mechanism 6 and a limiting mechanism 7 are provided on the second roller 2.

[0026] Specifically, the control mechanism 6 includes a slide groove 61, a slider 62, a handle 64 and a connecting rod 63. The slide groove 61 is opened on the outer wall of the second roller 2. The slider 62 is slidably installed on the inner wall of the slide groove 61. The connecting rod 63 is fixed on the side of the slider 62 close to the mounting block 4. The connecting rod 63 passes through the groove 3, and the connecting rod 63 can move left and right at the penetration. The end of the connecting rod 63 away from the slider 62 is fixed on the mounting block 4. The side of the slider 62 away from the connecting rod 63 is fixed with a handle 64. There are two groups of handles 64, and the two groups of handles 64 are symmetrically arranged with the center line of the first roller 1 in the vertical direction as the symmetry axis. Furthermore, when the roller needs to be replaced, the two sets of handles 64 can be moved closer to each other, so that the handles 64 can drive the slider 62 to approach the first roller 1, and the mounting block 4 can be extended into the groove 3 through the connecting rod 63, so that the device can be removed from the mounting bracket, thereby facilitating disassembly. When installation is required, the mounting block 4 can be moved into the groove 3 to compress the reset spring 5. When the mounting block 4 is aligned with the mounting hole on the mounting bracket, the handle 64 can be released, and the mounting block 4 can be extended into the mounting groove on the mounting bracket through the reset spring 5, so that the device can be installed, which is convenient for the staff to replace the roller.

[0027] Specifically, the limiting mechanism 7 includes a connecting groove 71, a transmission block 72, a connecting spring 73, a limiting block 74 and a limiting hole 75; the connecting groove 71 is arranged on the outer wall of the second roller 2, and a transmission block 72 is slidably installed on the inner wall of the connecting groove 71, and a connecting spring 73 is fixed on the side of the transmission block 72 close to the mounting block 4, and a connecting spring 73 is fixed on the inner wall of the connecting groove 71 on the side away from the transmission block 72. By setting the connecting spring 73, the transmission block 72 can be reset, and a limiting block 74 is fixed on the side of the transmission block 72 away from the connecting spring 73. A plurality of limiting holes 75 in a linear array are arranged on the outer wall of the first roller 1, and the size of the limiting holes 75 matches the size of the limiting blocks 74, and the transmission block 72, the connecting spring 73 and the limiting block 74 are fixed on the inner wall of the connecting groove 71. There are two groups of 73 and limit blocks 74, and the two groups of transmission blocks 72, connecting springs 73 and limit blocks 74 are symmetrically arranged with the center line of the first roller 1 in the vertical direction as the symmetry axis. When the transmission block 72 is pressed close to the mounting block 4, the connecting spring 73 will be compressed, and the limit block 74 will be moved out of the limit hole 75, so that the limit on the second roller 2 can be released, and the second roller 2 can be taken out of the first roller 1, so that the overall length can be adjusted. When the specified length is adjusted, the transmission block 72 can be released. Since the connecting spring 73 is in a compressed state, the limit block 74 can be extended into the corresponding first roller 1, so that the second roller 2 is fixed on the first roller 1, and the overall length can be adjusted according to production needs, thereby improving the practicability of the device.

[0028] Working principle: When the roller needs to be replaced, the two sets of handles 64 can be moved closer to each other, so that the handles 64 can drive the slider 62 to approach the first roller 1, and the mounting block 4 can be extended into the groove 3 through the connecting rod 63, so that the device can be removed from the mounting bracket, and then it is convenient to disassemble. When installation is required, the mounting block 4 can be moved into the groove 3 to compress the reset spring 5. When the mounting block 4 is aligned with the mounting hole on the mounting bracket, the handle 64 can be released. Through the reset spring 5, the mounting block 4 can be extended into the mounting groove on the mounting bracket, and the device can be installed, which is convenient for the staff to replace the roller.

[0029] When the transmission block 72 is pressed toward the mounting block 4, the connecting spring 73 will be compressed, and the limit block 74 will be moved out of the limit hole 75, so that the limit on the second roller 2 can be released, and the second roller 2 can be taken out from the first roller 1, so that the overall length can be adjusted. When the specified length is adjusted, the transmission block 72 can be released. Since the connecting spring 73 is in a compressed state, the limit block 74 can be extended into the corresponding first roller 1, so that the second roller 2 is fixed on the first roller 1, and the overall length can be adjusted according to production needs, thereby improving the practicability of the device.

[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
