Description

A track-type spiral automatic tensioning device

technical field

The utility model belongs to the technical field of belt conveyors, in particular to a track-type spiral automatic tensioning device.

Background technique

For the belt conveyor to operate normally, the conveyor belt must have a certain tension. Only when the conveyor belt has a certain tension can there be enough friction between the conveyor belt and the driving roller to ensure the normal operation of the conveyor belt driven by the driving roller. The tensioning device is an auxiliary device that provides tension for the normal operation of the belt conveyor, and is indispensable in the conveyor belt transportation system.

At present, the belt conveyor tensioning devices mainly include: hydraulic tensioning, screw tensioning, manual winch tensioning, heavy hammer tensioning and so on. Due to the adjustable tension and stroke, the hydraulic tensioning device has become a commonly used tensioning method for large-scale belt conveyor belts. However, the tensioning structure is complex and requires a separate hydraulic system, which is expensive and takes a long time The working system generates a lot of heat and consumes a lot of energy.

Patent CN201517593U discloses a belt horizontal spiral tensioning device, which includes a bracket and a bottom plate fixed on the bracket by bolts, the motor roller is fixed on the bottom plate, and a chute is provided on the bracket, and the relative tension between the bracket and the bottom plate is generated by adjusting the bolts. Displacement achieves belt tensioning. When the device is tensioned, it is necessary to repeatedly loosen and tighten the fixing bolts of the support and the base plate support, which cannot automatically adjust the tension force, and the support and the base plate are sliding friction during the tensioning process, so there is a large additional resistance.

This shows that the prior art needs to be further improved and improved.

detailed description

The utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the utility model is not limited to these embodiments.

As shown in Figures 1 to 2, a track-type spiral automatic tensioning device includes a tensioning car 6, a guide rail 7, a screw 5, a reducer 2, a motor 1 and an electric control box 8; the tensioning car 6 is placed In the guide rail 7, a roller 6.1 for tensioning the tape 10 is fixedly connected on the top, and a screw nut 6.2 threadedly connected with the lead screw 5 is arranged on the bottom surface; the input and output ends of the reducer 2 are respectively connected to the motor 1 and the lead screw through a coupling 5 connections, the motor 1 power line is connected in the electric box 8, and the electric control box 8 is provided with an external power supply.

The tensioning vehicle 6 is provided with guide wheels 6.3 that can roll along the guide rail 7 .

The two ends of the screw 5 are provided with screw bearing blocks 4 that limit its movement, and the screw bearing blocks 4 are provided with bearings 4.1.

A tension sensor 9 for detecting the tension of the adhesive tape 10 is installed inside the roller 6.1, which can transmit the tension signal to the electric control box 8 to control the motor 1 to automatically adjust the rotation direction and speed of the screw 5.

The guide rail 7 is a wrapping connection structure that can exert support force on the guide wheel 6.3 on the top, side and bottom.

The working principle of the utility model can be briefly described as follows: when the adhesive tape 10 is loose, the signal is transmitted to the electric control box 8 through the tension sensor 9, and the electric control box 8 controls the motor 1 to drive the screw 5 to rotate, and the tension car 6 is controlled by Force movement tightens the adhesive tape 10; when the adhesive tape 10 is too tight, the electric control box 8 controls the motor 1 to work to drive the lead screw 5 to rotate in reverse to maintain tension balance. If the tension tends to be stable in a certain period of time, the motor 1 stops working, and the tension balance is maintained by self-locking between the lead screw 5 and the lead screw nut 6.2.
