Sheet tension control system

Abstract

The invention discloses a bed sheet tension control system. A drive support is arranged at one end of a bed body in a hanging mode, a tension sensor is arranged outside the upper portion of the drive support, and a bed sheet is pressed between a first friction barrel and a second friction barrel after passing through a bed surface and the tension sensor; the second friction barrel is connected with a motor through a coupler, and the first friction barrel and the second friction barrel are mutually tightly compressed and are located on the inner sides of the drive support. A rolling barrel support is arranged at the other end of the bed body in a hanging mode, one end of an electric clutch is fixedly connected with the rolling barrel support, and the other end of the electric clutch is installed on a driven shaft; a paper bed sheet rolling barrel is sleeved on the driven shaft and is fixed through a chuck. The electric clutch, the motor and the tension sensor are controlled by an automatic tension controller. The bed sheet tension control system can be used in automatic bed sheet replacing equipment on a medical checking bed, achieve bed sheet tension control in the bed sheet replacing process, and guarantee smooth bed sheet replacing and emergency braking.

Description

technical field [0001] The invention belongs to the technical field of mechatronics, and relates to a bed sheet tension control system of a medical examination bed automatic bed sheet replacement device. Background technique [0002] For a long time, medical resources have been in short supply, and some examinations of patients, such as B-ultrasound and CT, have a serious queue phenomenon. Most of the bed sheets in the examination process are manually replaced, which reduces the efficiency of examinations to a certain extent and increases the workload of medical staff. Extra workload. Therefore, when patients often undergo the examination process, it is impossible to achieve "one person, one change" of the examination bed sheets. In view of the above-mentioned present situation, it is very necessary to provide a new type of automatic bed sheet replacement equipment for medical examination beds. The equipment can not only ensure that the inspection sheets are "one change pe...

Problems solved by technology

[0003] The tension control of bed sheets is very important in the process of bed sheet replacement. It can ensure the smooth replacement of bed sheets (constant tension control). If the tension is too large, the paper will be stretched, deformed or even broken. Uneven

The bed sheet equipment of the existing examination table does not include a tension control device. Usually, the driving motor stops directly. Although it can be braked, due to the inertia of the bed sheet roller, it is easy to cause a part of the bed sheet to be transmitted, causing problems such as unevenness of the bed sheet
