Description

Device to prevent belt slipping and deviation

technical field

The utility model belongs to the technical field of cigarette machinery and equipment, in particular to an improved device for conveying equipment in tobacco shred processing equipment.

Background technique

In the prior art, in the tobacco shred processing equipment, the storage type feeder is a common temporary storage type material storage and feeding device, which saves the time for brand change, stabilizes the flow of materials in production, and ensures the safety of production and processing. It plays a very important role in continuity and ensuring the machining accuracy of subsequent processes. In the production line of the silk workshop, the feeder is widely used before or during the processing procedures such as feeding, flavoring, drying and blending. In the actual production process, the phenomenon of material discontinuity and flow instability often occurs. After inspection, it was all caused by the deviation and slippage of the bottom belt of the current silo. This kind of failure had a great impact on the production continuity and processing accuracy of the subsequent feeding, drying stems and other processes, and had a great impact on the stable feeding, drying The production quality of cut stems and the control of the moisture content of cut stems are also very unfavorable. Through the investigation, it was found that the deviation and slippage of the belt at the bottom of the feeding bin were due to the uneven force on both sides of the belt caused by the step-by-step laying method of the feeding bin, the stickiness of the incoming material and the load. Caused by the negative friction of the roller parts.

Utility model content

Aiming at the above-mentioned deficiencies of the prior art, the technical problem to be solved by the utility model is to provide a device for preventing belt slipping and deviation, which can prevent the belt from slipping and deviation, thus ensuring the normal and stability of the subsequent process.

The technical solution of the utility model is: the device for preventing the belt from slipping and running off includes a drum and a belt, the belt is sleeved on the drum, a rubber coating layer is arranged on the outer surface of the drum, and left, middle and right three corners are arranged on the rubber coating layer. The grooved ring, the side of the belt in contact with the outer surface of the drum is provided with three guide bars that can be inlaid with the grooved ring. The guide bar is composed of a plurality of evenly arranged and intermittent protrusions connected in a line. The cross-sectional height and width of the groove ring are both 1-3mm larger than the cross-sectional height and width of the guide bar.

The utility model has the advantages of reasonable design, simple structure, low added cost, remarkable technical effect and guaranteed production continuity and processing precision.

Detailed ways

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail. As shown in FIG. 1 , a belt 8 is sleeved outside the drum 1 , and a guide bar 4 is arranged on the belt 8 . As shown in Figure 2, the drum 2 is provided with grooved rings 6, and the three guide bars 4 are fitted with the left, middle and right three grooved rings 6 and can move relative to each other, thereby ensuring the slipping and deviation of the belt. This mosaic-like structure uses guide bars and grooved rings to limit the belt offset within a certain range. The guide strip 4 is evenly bonded on the belt 8 by hot-bonding technology, and the rubber covering layer is installed on the drum 1, and 3 groove rings 6 equidistant from the guide strip are opened on the rubber covering layer 2. Groove ring 6 grooves are similar to guide bar 4 shapes, but the groove ring upper and lower side lengths are slightly larger than the guide bar lower and upper side length correspondingly, so that there is a certain gap 9 between the guide bar and the groove ring. The matching operation between the guide bar 4 and the grooved ring 6 makes the deviation of the belt 8 only in the grooved ring 6, and the axial relative movement between the belt 8 and the idler roller is reduced, preventing or delaying the movement of the belt. 8 off course. The 3 guide strips 4 thermally bonded on the belt are similar to the 3 "reinforcing ribs" on the belt, which obviously improves the tensile strength of the belt, and has a remarkable effect on solving the slipping phenomenon of the belt 8. In the cross-sectional view in the above figure, due to the small size of the figure, in order to show it clearly, the hatching is not filled, which does not affect the understanding of the figure.
