Description

Technical Field

[0001] This utility model relates to the field of cigarette machinery and equipment technology, and more specifically, to an installation structure for a tensioning wheel of a packaging machine. Background Technology

[0002] In the power input mechanism of the cigarette pack extractor of the existing ZB416 cigarette packaging machine, the toothed belt tensioning device is a cantilever structure with unidirectional double-sided tension and adjustable center distance. The tensioning wheel is mounted on a fixed plate via a small shaft, similar to a cantilever beam structure in engineering mechanics.

[0003] However, the small shaft of the tensioner is subjected to unidirectional double-sided tension. The bearings and bearings of this structure are subjected to large tension, and the bearings and shafts are very easy to be damaged, causing the support shaft to deflect. This results in the toothed belt running off-center on the pulley, leading to abnormal wear or detachment of the toothed belt, which affects the continuous and stable operation of the equipment.

[0004] Therefore, how to provide an installation structure for the tensioning wheel of a packaging machine has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] One objective of this invention is to provide a new technical solution for the installation structure of the tension wheel of a packaging machine.

[0006] According to a first aspect of the present invention, an installation structure for a tensioning wheel of a packaging machine is provided, comprising: a fixed bracket, a base plate, a tensioning wheel, a toothed belt, and a fixing assembly;

[0007] The base plate is provided with an oblong hole, the top of the fixed bracket is provided with a stiffening plate, the stiffening plate and the interior of one side of the fixed bracket form a mounting groove, the width of the mounting groove is equal to the thickness of the base plate, and the toothed belt is sleeved on the tensioning wheel.

[0008] The fixing component includes a mounting shaft and fixing holes. The fixing holes are respectively located on both sides of the fixing bracket.

The toothed belt 4 is sleeved on the tensioning wheel 3.

[0027] The fixing component 5 includes a mounting shaft 51 and a fixing hole 52. The fixing holes 52 are respectively located on both sides of the fixing bracket 1. The mounting shaft 51 passes through the fixing hole 52, the waist-shaped hole 21 and the tensioning wheel 3 in sequence. The top of the base plate 2 is located in the mounting groove.

[0028] This invention creates an installation groove by forming a mounting plate 11 inside one side of the fixed bracket 1, with the width of the groove equal to the thickness of the base plate 2. The toothed belt 4 is fitted onto the tensioning wheel 3. Fixing holes 52 are respectively set on both sides of the fixed bracket 1. The mounting shaft 51 passes through the fixing holes 52, the oblong hole 21, and the tensioning wheel 3 in sequence. The top of the base plate 2 is set in the installation groove. In use, the position of the tensioning wheel 3 can be adjusted through the oblong hole 21, so that the toothed belt 4 on the tensioning wheel 3 is always in a taut state. By installing the mounting shaft 51 on both ends of the fixed bracket 1, and by using the rib 11 and the fixed bracket 1 to limit the base plate 2, the tensioning wheel 3 can be stably installed on the fixed bracket 1, and the force on the mounting shaft 51 is more even. This solves the problem of abnormal wear or detachment of the toothed belt 4 in the prior art, and improves the stability of the packaging machine operation.

[0029] In one embodiment of the installation structure of the tensioning wheel of the packaging machine of this utility model, the fixed bracket 1 includes a connecting plate 12, a first support plate 13 and a second support plate 14.

The tensioning screw 58 passes through the through hole and is connected to the first threaded hole 57.

[0036] Specifically, this utility model achieves the fixation of the mounting shaft 51 by using a tensioning screw 58 through the through hole and threadedly connecting it to the first threaded hole 57, thereby preventing the entire frame structure from deflecting.
