Problems solved by technology

Some of the existing hot pressing roller technology is to place several linear heating tubes or electric heating wires in the hot pressing roller body. Due to the distance between the linear electric heating tubes, the surface of the hot pressing roller body will be heated unevenly, and the surface There is a large temperature difference at each point; some heat-pressing rollers have a hollow structure with various high-temperature-resistant heat-conducting oils built in, and oil leakage must be prevented during the entire transmission process. Once the oil leaks, the product will be scrapped; some electric heating tubes are fixed on two sides. On the flange plate at the end, and the flange plate rotates with the body of the hot pressing roller, so that the wires connected to the external power supply also move, which is prone to wire knotting or leakage accidents; and the overall structure of the hot pressing roller is too complicated, and the layout The space of the winding point of the belt winding machine is small, and the possibility of adding mechanisms is small

Embodiment Construction

[0019] Describe the present invention below in conjunction with specific embodiment:

[0020] The hot pressing roller device for the tape winding machine in this embodiment includes a hot pressing roller body 4 , a central shaft 1 , an electric heating tube 3 and a bushing 14 .

[0021] The body of the hot pressing roller is a hollow cylindrical structure with one end open, the open end of the hot pressing roller body is stepped, and the center of the other end of the hot pressing roller body has a stepped through hole.

[0022] There is a central shaft passing through the central axis of the heat press roller body. Both ends of the central shaft are stepped. There is a keyway on the second stepped shaft at one end for connecting with the bushing, and the second stepped shaft at the other end is used for For interference fit with the small end bearing 2.

[0023] The central shaft and the inner ring of the small-end bearing have an interference fit, and the outer ring of the ...

Abstract

The invention provides a hot-pressing roll device for a cloth tape winding machine. The hot-pressing roll device comprises a hot-pressing roll body, a central shaft, an electric heating tube and a bushing, wherein the hot-pressing roll body is of a hollow cylindrical structure of which one end is opened; the bushing is arranged at the opening end of the hot-pressing roll body and is connected with the hot-pressing roll body through a bearing in a sealing way; a central shaft penetrates through along a central line of the hot-pressing roll body; one end of the central shaft is connected with the hot-pressing roll body through a bearing in a sealing way; the bushing penetrates through the other end of the central shaft and is fixedly connected with the other end of the central shaft; the electric heating tube is a spiral electric heating tube; and the electric heating tube is arranged inside the hot-pressing roll body and is coaxial with the hot-pressing roll body. When the hot-pressing roll body rotates, the bushing and an electric heater fixed on the bushing do not rotate, and thus on one hand, the external connection of a power supply is facilitated, and on the other hand, a sensor can be arranged in the hot-pressing roll body for measuring the temperature, and thus temperature control with high precision can be realized.

Description

technical field [0001] The invention relates to a cloth tape winding technology, in particular to a hot pressing roller device for a cloth tape winding machine. Background technique [0002] The function of the hot pressing roller device used on the cloth tape winding machine is to install the electric heating tube inside the pressure roller, and the heat will cause the outer surface of the pressure roller to heat up through heat conduction, so that the prepreg tape attached to the pressure roller is under pressure. While maintaining a good melting state, so as to obtain high-quality winding products. Some of the existing hot pressing roller technology is to place several linear heating tubes or electric heating wires in the hot pressing roller body. Due to the distance between the linear electric heating tubes, the surface of the hot pressing roller body will be heated unevenly, and the surface There is a large temperature difference at each point; some heat-pressing rolle...
