[0023] One end of the connecting pipe 4 is connected with a hot air machine, the hot air machine blows the air capable of melting the first high polymer coiled material 5 and the second high polymer coiled material 6 into the inner air heating box structure 10 outside the box structure 3, the cross section of the whole inner air heating box structure 10 is set as an inverted trapezoidal structure, the inner air heating box structure 10 can blow the air outside the air outlet 12, the gap between the first high polymer coiled material 5 and the second high polymer coiled material 6 is at the upper end of the long groove 9, and the hot air melts the gap between the first high polymer coiled material 5 and the second high polymer coiled material 6 and welds them.

[0024] The inner cavity 14 is arranged on both sides of the outer cavity 18, the upper end of the inner wall of the inner cavity 14 is connected with the spring 13, the lower end of the spring 13 is connected with the movable plate 15, the lower end of the movable plate 15 is fixedly connected with the rubber strip 16, the rubber strip 16 penetrates through the bottom end wall of the inner cavity 14, one end of the rubber strip 16 is pressed on the second high polymer coiled material 6, and the other end of the rubber strip 16 is pressed on the first high polymer coiled material 5.

[0025] When the first high polymer coiled material 5 and the second high polymer coiled material 6 are moved and inserted at the lower end of the outer air outlet box structure 3, the spring 13 in the inner cavity 14 presses downward the movable plate 15, the movable plate 15 is also driven to move downward, the rubber strip 16 is also pressed downward, and the two rubber strips 16 are pressed on the upper end of the first high polymer coiled material 5 and the upper end of the second high polymer coiled material 6 respectively, the upper end of the first high polymer coiled material 5 and the upper end of the second high polymer coiled material 6 are fixed, and the fixing performance of the first high polymer coiled material 5 and the second high polymer coiled material 6 on the welding platform 1 is improved.

[0026] The middle of the upper end of the welding platform 1 is provided with the long groove 9, the two sides of the welding platform 1 are fixedly connected with the top block 7, and the upper end of the cross section of the top block 7 is provided with a semicircular convex structure, the first high polymer coiled material 5 and the second high polymer coiled material 6 are lifted up by the top block 7, a part of the first high polymer coiled material 5 and the second high polymer coiled material 6 is pressed to the middle by the lifting action, the gap between the first high polymer coiled material 5 and the second high polymer coiled material 6 is tightly fitted, and the first high polymer coiled material 5 and the second high polymer coiled material 6 are prevented from sliding to the two sides under the action of gravity.

[0027] The four corners of the welding platform 1 are fixedly connected with the positioning mechanism 8, the positioning mechanism 8 comprises a connecting strip 801, one end of the connecting strip 801 is fixedly connected with a clamping strip 802, the two sides of the clamping strip 802 are fixedly connected with clamping pieces 803, and the first high polymer coiled material 5 and the second high polymer coiled material 6 are pressed on the lower end of the clamping strip 802.

[0028] The positioning mechanism 8 of the whole is made of elastic metal, the bending of the clamping sheet 803 can position and fix the upper end of the first polymer coiled material 5 or the second polymer coiled material 6, and the bending of the clamping strip 802 can also position and fix the upper end of the first polymer coiled material 5 or the second polymer coiled material 6. Through the arrangement, the positioning mechanism 8 at the four corners of the welding platform 1 can position and fix the first polymer coiled material 5 and also position and fix the second polymer coiled material 6.

[0029] In use, the first polymer coiled material 5 is placed on one side of the upper end of the welding platform 1, and the second polymer coiled material 6 is placed on the other side of the upper end of the welding platform 1. The positioning mechanism 8 at the front and rear ends of one side of the welding platform 1 extrudes and fixes the first polymer coiled material 5, and the positioning mechanism 8 at the front and rear ends of the other side of the welding platform 1 extrudes and fixes the second polymer coiled material 6.

[0030] When the hot air machine outside fills the high-temperature gas into the inner air heating box structure 10 through the connecting pipe 4, the plurality of heat preservation plates 11 inside the inner air heating box structure 10 are powered on to heat the air, so that the temperature of the high-temperature gas gradually decreases when it enters the inner air heating box structure 10. The plurality of heat preservation plates 11 are staggered in the inner air heating box structure 10. This arrangement can buffer the high-temperature gas entering the inner air heating box structure 10, so that the gap between the first polymer coiled material 5 and the second polymer coiled material 6 does not deform when the high-temperature gas blows downward at a high speed. The staggered arrangement of the plurality of welding platforms 1 increases the contact area of the high-temperature gas with the heat preservation plates 11 in the inner air heating box structure 10, thereby improving the heat preservation efficiency of the heat preservation plates 11.

[0031] The spring 13 stretches downward to stretch the movable plate 15 and the rubber strip 16. This allows the rubber strip 16 to fix the first polymer coiled material 5 and the second polymer coiled material 6, and the rubber strip 16 can block most of the high-temperature gas from flowing out of the two ends of the outer air outlet box structure 3. The high-temperature gas flows out of the outlet 17 at the upper end of the outer air outlet box structure 3, so that the high-temperature gas only contacts the gap between the first polymer coiled material 5 and the second polymer coiled material 6 and melts it, thereby avoiding the high-temperature gas from melting a large area of the first polymer coiled material 5 and the second polymer coiled material 6, and avoiding damage caused by the melting of a large area of the first polymer coiled material 5 and the second polymer coiled material 6.

[0032] Then, the high-temperature gas is blown out through the gas outlet 12, and the high-temperature gas only melts the gap between the first high-molecular material roll 5 and the second high-molecular material roll 6, so that the first high-molecular material roll 5 and the second high-molecular material roll 6 can be heat-welded as a whole.
