Description

Profile spiral tube winding machine

The invention relates to a winding device for a plastic profile pipe, in particular to a device for winding a special plastic profile into pipes of different calibers. technical background

The profile spiral winding pipe feeds the profile into the winding roller of the winding machine. In the rotation and rolling, the spiral forming of the pipe is realized by the fastening structure of the profile. Due to the fact that its profile can be factory-produced, it can be wound on site and can save production cost and transportation cost. Compared with cement pipeline, profile spiral wound pipe has light weight, acid and alkali corrosion resistance, wear resistance and shock resistance. Good performance, strong resistance to displacement, and more and more widely used in the fields of sewage, water diversion, irrigation, transportation and communication cable laying.

However, the winding machine for winding the above-mentioned profile spirally wound pipe in the prior art is often designed for a specific profile. When the profile is changed, the original winding machine cannot be used; in addition, the existing winding machine is wound around the pipe It is only possible to cut the pipe manually, and it is often difficult to cut by cutting into the pipe. It is difficult and inefficient, and the working conditions are bad. Since the cut end faces are not aligned, it is not conducive to the connection between the pipes, and secondary processing is required. Summary of the invention

In view of the above-mentioned deficiencies of the prior art, it is an object of the present invention to provide a novel profile spiral winding machine which not only adapts to the change of the profile, but also automatically cuts the wound pipe.

The technical solution adopted for achieving the above object is such that a profile spiral pipe winding machine comprises a frame and a working 'panel erected on the frame, and the group has a circumferentially distributed group on the working panel. a pressing mechanism composed of a roller and a pressing roller, wherein a guiding mechanism is mounted on an outer side or an inner panel of the circumference surrounded by the pressing mechanism, and a pair of rotating rollers is formed at a side of the pressing mechanism at the lowermost portion of the panel a feeding mechanism; on the back side of the panel, a transmission mechanism for driving the pressing mechanism and the rotation of the feeding mechanism rotating roller; wherein: a telescopic arm and a cutting head are mounted in a circumference surrounded by the pressing mechanism at the center of the panel a cutting mechanism; the pressing roller of the pressing mechanism is formed by a stepping sleeve and a central shaft key connection, and the diameter or thickness of the grading sleeve is stepwisely reduced from the central shaft root to the shaft end stepwise, and the sleeve is arranged on each stage. With a guide ring. A groove is arranged on the classifying sleeve of the pressure roller of the pressing mechanism in the above device. Another profile can be used to increase the thickness of the pipe or increase the strength of the pipe as needed. - The above-mentioned pressing mechanism and guiding mechanism are radially adjustable to manufacture pipes of different calibers.

The working principle of the above device is as follows: the profile is placed between a pair of rollers of the feeding mechanism, and the profile is first fed between the sleeve of the maximum diameter or thickness of the pressure roller of the pressing mechanism and the roller, Under the guidance of the circumferential guide block, that is, the guide ring of the pressure roller, the profiles enter the sleeve of the maximum diameter or thickness of each pressing mechanism one by one, and the sleeve is wound into a ring shape, which is caused by the buckle structure at the edge of the profile. The profiles are fastened to each other during the winding process. When the device has a gluing mechanism, the profiles are bonded to each other while being fastened together to form a solid spiral pipe. When the thickness of the spiral pipe is to be increased, the pressing mechanism is used. The double-structured spiral tube can be obtained by filling the profile between the sleeve of the first diameter or thickness of the pressure roller and the rotating roller; thus, the number of stages of the grading sleeve of the pressure roller can determine that the device can be wound around the spiral tube The number of layers. When the stepping sleeve of the pressing roller of the pressing mechanism has a groove, another strip profile can be inserted into the buckle groove of the first layer during the winding process to form another reinforcing layer. Moreover, the degree of density of the reinforcing layer can be changed according to actual needs. For example, the strip profile can be inserted into each groove of the sleeve for winding, or can be wound by one or two grooves. When the spiral pipe is wound for a sufficient length, the cutting mechanism is activated to extend the telescopic arm to the inner wall of the pipe, start the cutting head motor, rotate the disk saw, and rotate the pipe or cutting device to obtain a neat end face. '

The present invention has a somewhat significant feature due to the above structure, that is, the present invention provides an efficient means for winding a pipe in the field, which can be wound with a spiral pipe of different diameters and thicknesses, and can also be wound with different profiles. Meet the actual needs. After the pipeline is processed, it is automatically cut by the cutting mechanism to obtain a neat pipe section, which avoids the cumbersome secondary processing. The device has a simple structure, multiple functions and flexible use. DRAWINGS
