[0002] When processing plastic or rubber materials, they can be stretched by a stretching machine to stretch the materials to the required length or thickness. However, since plastic or rubber materials are generally not easy to stretch and deform under normal conditions, they need to be softened by a heating mechanism before they can be stretched.
[0003] The stretching heating mechanism used in the existing stretching machines on the market heats the material and then pulls the material from both ends to stretch and extend the material. However, the heated material softens and is pulled, and the heated position is prone to fall, so the overall length of the pulled material will be slightly longer than the required length. For this reason, we propose a stretching heating mechanism for a stretching machine. Utility Model Content

[0026] In this embodiment, when in use, the plastic parts that need to be stretched are placed between several rollers 9 and pressure rollers 10, and then the heater 3 is started. The heater 3 controls all the heating rods 4 inside the heating chamber 2 to start. After the heating rods 4 are started, they heat the surrounding air. The air conducts the heat to the rollers 9 and the pressure rollers 10. After the rollers 9 and the pressure rollers 10 are heated, they heat the plastic parts placed therein. By heating the plastic parts from the top and bottom at the same time, the softening speed of the plastic parts can be increased, and when stretched, the softened position in the middle of the plastic parts will not fall, so that the length after stretching will not have too large an error.
[0027] like Figure 1 and Figure 4 As shown, a support seat 14 is fixedly installed on the inner side of the top of the mounting frame 12, a second cylinder 15 is fixedly installed on the top of the support seat 14, an arc-shaped clamping plate 16 is fixedly installed on the output shaft of the second cylinder 15 through the support seat 14, and the lower surface of the arc-shaped clamping plate 16 is movably connected to the surface of the pulling roller 11;
[0028] In this embodiment, after the plastic part is placed between the support roller 9 and the pressure roller 10 to soften, a tool is used to pull the two ends of the plastic part to the upper surface of the pulling roller 11, and then the second cylinder 15 is started. After the second cylinder 15 is started, the arc clamping plate 16 is pressed down, and the two ends of the plastic part are clamped and fixed by the arc clamping plate 16 and the pulling roller 11, and then the first cylinder 13 is started. After the first cylinder 13 is started, the mounting frame 12 is controlled to be lifted. After the mounting frame 12 is lifted, the plastic part is pulled by the pulling roller 11, so that during the pulling, the two ends of the plastic part will not fall, and the stretched length can be controlled by controlling the lifting distance of the mounting frame 12, so as to achieve the purpose of facilitating pulling;
[0029] like Figure 1 and Figure 3 As shown, two third cylinders 17 are fixedly installed on both sides of the bottom ends of the two side frames 6, and the output shafts of the four third cylinders 17 pass through the fixed plate 7 and are respectively connected to both sides of the bottom ends of the two movable plates 8;

When the four third cylinders 17 are started at the same time, the two movable plates 8 are lifted. After the two movable plates 8 are lifted, the plurality of pressure rollers 10 installed inside thereof are controlled to rise synchronously, so that the distance between the supporting rollers 9 and the pressure rollers 10 can be expanded, and then the plastic parts can be placed therein. In the above manner, plastic parts of different sizes can be conveniently lifted for heating;

[0032] In this embodiment, when the mounting frame 12 falls, the bottom end of the mounting frame 12 is restricted by the fixing seat 18, so that the falling distance of the mounting frame 12 is effectively controlled;
[0033] Working principle: When in use, the plastic parts that need to be stretched are placed between several rollers 9 and pressure rollers 10, and then the heater 3 is started. The heater 3 controls all the heating rods 4 inside the heating chamber 2 to start. After the heating rods 4 are started, they heat the surrounding air. The air transfers the heat to the rollers 9 and the pressure rollers 10. The rollers 9 and the pressure rollers 10 are heated to heat the plastic parts placed therein. When the plastic parts are placed between the rollers 9 and the pressure rollers 10 and softened, a tool is used to pull the two ends of the plastic parts to the upper surface of the pulling roller 11, and then the second cylinder 15 is started. After the second cylinder 15 is started, the arc clamping plate 16 is pressed down, and the two ends of the plastic parts are clamped and fixed by the arc clamping plate 16 and the pulling roller 11. Then the first cylinder 13 is started. After the first cylinder 13 is started, the mounting frame 12 is controlled to be lifted. After the mounting frame 12 is lifted, the plastic parts are pulled through the pulling roller 11.
