Description

Technical Field

[0001] The invention belongs to the technical field of medical product production equipment and relates to a heating roller structure and method in different temperature ranges. Background Art

[0002] Among medical supplies, there is a barium wire gauze used in surgery. Its preparation process is that a gauze roll is released by a release mechanism, and then it is transferred to a high-speed folding machine for folding through a transfer roller after being atomized and moistened. The purpose of moistening is to make the gauze soft. When the gauze released from the gauze roll passes through the transfer roller, if it is not heated, it cannot meet the subsequent process requirements. If the heating is too high or a large area is heated, the previous atomization and moistening will fail, resulting in the gauze piece being difficult to fold in the later stage. Dislocation and stacking are likely to occur during the folding process, resulting in the gauze piece not being able to be folded in the center.

[0003] During the release of the gauze roll, a barium wire is also released with it. The barium wire is located in the barium wire box and moves synchronously with the gauze released by the gauze roll by pulling it. During the gauze transfer process, the barium wire is attached to the gauze sheet and cannot be broken. The purpose of the barium wire is to develop images, facilitate tracking during the operation, and avoid leaving the patient's surgical area after the operation. Summary of the invention

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a heating roller structure with different temperature sections, which includes a roller shaft, a roller ring, a heating ring, an insulation ring and a heating tube; the roller shaft axially passes through the roller ring, the heating ring and the insulation ring and is connected with them to form a roller body, the insulation ring is distributed between multiple roller rings and multiple heating rings at intervals, and the multiple heating tubes are distributed in a ring shape and axially pass through the roller ring, the heating ring and the insulation ring; the surface of the roller body is divided into a folding heating section, a hot line heating section and an insulation section.

[0006] A temperature sensor is arranged at one end of the roller body, and the sensing end of the temperature sensor passes through the folding heating section, the ironing heating section and the heat insulation section.

[0007] The temperature sensor is a multi-point stepped temperature sensor, and the sensing points of the sensing end are respectively located in the folding heating section and the ironing line heating section.

[0008] The roller ring, heating ring and heat-insulating ring are cylinders with the same diameter, with an axial hole at the center thereof connected to the roller shaft, and multiple pipe holes are arranged in a ring around the axial hole to cooperate with the heating pipe.

[0009] At least one penetrating sensing hole is arranged on the periphery of the shaft holes of the roller ring, the heating ring and the heat insulation ring, and the sensing end of the temperature sensor is located in the sensing hole.

[0010] The heating tube comprises a heating wire between an inner insulating layer and an outer insulating layer, a conducting wire in the inner insulating layer is connected to the heating wire, and a heat conducting layer is arranged on the surface of the outer insulating layer.

[0011] The heating wire is a segmented structure, the length and resistance of each segment are different, and two wires are led out of each segment.

[0012] The heating wire is connected to a temperature controller, the temperature controller is electrically connected to a PLC control system, and the temperature controller is also connected to a heating power supply.

[0013] The temperature sensor is electrically connected to the PLC control system.

[0014] The heating roller structure with different temperature ranges and the heating control method as described above include the following steps:

[0015] S1, preheating, the PLC control system sends a signal to the temperature controller, and the temperature controller turns on the heating power supply and the heating wire after receiving the signal; in this step, the atomized and moistened gauze passes through the transfer roller and contacts the folding heating section, the ironing heating section and the insulation section, and the barium wire is located on the surface of the gauze and passes through the ironing heating section;

[0016] S2, transfer, the temperature sensed by the temperature sensor is transmitted to the PLC control system in real time. When the temperature of the folding heating section and the ironing heating section reaches the set temperature, the roller rotates, the folding heating section and the ironing heating section heat the non-folding area of ​​the gauze, and the ironing heating section also heats the barium wire;

[0022] The main beneficial effects of the present invention are:

The roller rings, heating rings and heat insulating rings have the same structure but different materials.

[0024] The roller surface is divided into a folding heating section, a hot line heating section and a heat insulation section, so that different areas of the gauze can be heated when it passes through.

[0025] The edge folding heating section and the hot line heating section are separated by a heat insulation section to avoid temperature cross-talk between the edge folding heating section and the hot line heating section.

[0026] The heating tube axially passes through the roller ring, heating ring and heat insulation ring on the roller body, and adopts an outer insulation layer insulation and heat conduction layer heat conduction structure to avoid electrical conduction of the heat conduction layer.

[0027] The heating wire in the heating tube is arranged in sections, and each section corresponds to the folding heating section and the ironing line heating section one by one, which is conducive to adopting different heating modes for each section to improve the folding quality of the gauze piece and the attachment quality of the barium wire.

[0028] The roller body only heats the folding heating section and the hot line heating section, and does not need to be heated as a whole, which has obvious energy-saving effect. BRIEF DESCRIPTION OF THE DRAWINGS
