Description

Technical Field

[0001] The utility model relates to the technical field of cigarette machinery and equipment, and more particularly to a transmission belt slippage detection device used in cigarette factories. Background Art

[0002] Belt conveyors are commonly used in tobacco industry silk production lines to transport materials. In actual production, because each brand of material consists of a unique tobacco leaf blend, resulting in variations in moisture content and looseness, the belt can sometimes become overloaded and crushed, causing slippage and interrupted material flow, severely impacting product quality and production efficiency. Furthermore, when the belt slips, the conveyor's active roller idles, wasting energy. More importantly, even after the belt slips, the conveyor's upstream process continues to discharge material, causing a large accumulation of material on the conveyor. Cleaning the material is time-consuming and labor-intensive, increasing the operator's workload. A non-contact belt slip detection device is designed to detect belt slippage. It detects belt slippage by detecting vibration, magnetic fields, or current changes in the belt.

[0031] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0032] like Figures 1 to 5 As shown, an embodiment of the present invention provides a conveyor belt slippage detection device for a cigarette factory, comprising: a frame 1, a driven wheel 2, a rotating roller 3, a fixing component 4, a clamping component 5 and a speed detection component 6.

The spring 57 is sleeved on the fixed shaft 56 and is respectively connected to the movable block 53 and the inner wall of the installation cavity. The first end of the fixed shaft 56 is connected to the clamping block 55, and the clamping block 55 is clamped with the second end of the movable block 53. The second end of the fixed shaft 56 passes through the frame 1 and is connected to the speed detection assembly 6.

[0035] The speed detection assembly 6 is connected to the outer side walls of the driven wheel 2 and the rotating roller 3 and is used to detect the speeds of the driven wheel 2 and the rotating roller 3 .

[0036] Specifically, the transmission belt is driven from the rotating roller 3 and the driven wheel 2 , the top of the pressing block 51 passes through the frame 1 to the top of the frame 1 , and the supporting frame 54 supports and fixes the movable block 53 .

[0037] During use, by pressing the pressure block 51 downward, the pressure block 51 drives the movable block 53 to move toward the interior of the installation cavity.

The speed detection component 6 detects the rotation speed of the rotating roller 3 and the driven wheel 2, and then compares whether the conveyor belt is slipping. When the speed detection component 6 detects that the speed of the running second roller 32 and the driven wheel 2 exceeds 25-30% of the normal speed, the surface conveyor belt is slipping.

[0038] Furthermore, since the press-type clamping assembly 5 is adopted, it is convenient to install and fix the speed detection assembly 6.

The utility model installs the speed detection component 6 on the front side of the driven wheel 2 and the front side of the rotating roller 3 through the clamping component 5, detects the rotation speed of the rotating roller 3 and the driven wheel 2, and then can compare whether the transmission belt is slipping.
