Description

Technical Field

[0001] The present application relates to the technical field of conveying equipment, and in particular to a conveyor belt differential speed adjustment device. Background Art

[0002] Beverages that can be placed upright, such as cans, are transported by conveyor belts during the production process. In order to improve the conveying speed and save space, the area of ​​the conveyor belt is expanded in the middle of the conveying process. The conveying speed of this part of the conveyor belt will be slowed down. This part is called the storage part. The end of the storage part will enter the narrower conveyor belt, which has a faster conveying speed and keeps narrowing until only a single can can pass through.

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1-3 This application is described in further detail.

[0028] The embodiment of the present application discloses a conveyor belt differential speed adjustment device.

[0029] refer to Figure 1 and Figure 2 The conveyor belt differential adjustment device includes a protection box 1, a first gear 2, a second gear 3 and a drive chain 4. The protection box 1 is installed on one side of the conveyor belt frame and is opposite to the driving rollers of the two conveyor belts with different rotation speeds. The driving shafts of the two conveyor belts with different rotation speeds extend into the protection box 1, and the side of the protection box 1 away from the conveyor belt frame can be opened. The first gear 2 is fixedly mounted on the driving shaft of one of the conveyor belts located in the protection box 1. The second gear 3 is fixedly mounted on the driving shaft of the other conveyor belt located in the protection box 1. The drive chain 4 is meshed with the first gear 2 and the second gear 3 at the same time. The protection box 1 is provided with a tensioning assembly 5 for tightening the drive chain 4.

[0030] Through the meshing relationship between the driving chain 4 and the first gear 2 and the second gear 3, two conveyor belts can be driven by one motor, and the two conveyor belts can rotate at different speeds, thereby saving costs and energy consumption. The protective box 1 can effectively protect the first gear 2, the second gear 3 and the driving chain 4. The tensioning component 5 can always keep the driving chain 4 in a tensioned state, thereby improving the stability of the rotation of the two conveyor belts.

[0031] refer to Figure 2 and Figure 3 The tensioning assembly 5 includes a support column 51, an extension plate 52, a third gear 53 and a positioning rod 54. The support column 51 is installed on the inner wall of the protective box 1 and is located below the drive chain 4. A rotating ring groove 511 is provided at the end of the support column 51, and the extension plate 52 is sleeved in the rotating ring groove 511. A fastening stud 513 is threadedly connected to the end of the support column 51. The fastening stud 513 is sleeve-shaped, and the threads are distributed on its own circumferential inner wall. The fastening stud 513 is threadedly connected to the circumferential outer wall of the rotating ring groove 511. A rubber gasket 512 is fixed on the end face of the rotating ring groove 511, and the extension plate 52 is provided with a fastening groove 521 for the end of the fastening stud 513 to be pressed against. The fastening stud 513 presses the extension plate 52 against the end face of the rotating ring groove 511. The third gear 53 is rotatably connected to the end of the extension plate 52 away from the support column 51, and the third gear 53 meshes with the drive chain 4 and tightens the drive chain 4. The positioning rod 54 is rotatably connected to one end of the extension plate 52 away from the support column 51 . A plurality of positioning grooves 11 are equidistantly formed on the inner bottom wall of the protection box 1 . The positioning rod 54 can be rotatably inserted into the positioning grooves 11 .

[0032] After replacing the first gear 2 and the second gear 3, the third gear 53 is meshed and tightened with the drive chain 4 by rotating the extension plate 52. Then, the fastening stud 513 is rotated so that the fastening stud 513 presses the extension plate 52 against the rubber gasket 512 to increase the friction of the rotation of the extension plate 52 and improve the stability of the installation of the extension plate 52. Then, the positioning rod 54 is rotated so that the positioning rod 54 is inserted into the corresponding positioning groove 11 to support the extension plate 52, further improving the stability of the position of the extension plate 52, so that the third gear 53 can stably mesh with the drive chain 4 and tighten the drive chain 4.

[0033] The implementation principle of a conveyor belt differential speed adjustment device in the embodiment of the present application is as follows: through the meshing of the drive chain 4 with the first gear 2 and the second gear 3, one motor can be used to stably drive the two conveyor belts to rotate at a differential speed, saving the installation of one motor, saving costs and saving energy consumption. The third gear 53 is meshed and tightened with the drive chain 4 by rotating the extension plate 52, and then the positioning rod 54 is rotated into a suitable positioning groove 11, and finally the fastening stud 513 is rotated to fasten the extension plate 52, thereby improving the stability of the rotation of the drive chain 4.

[0034] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
