The length of the mounting strip 203 is greater than the length of the clamping strip 201, and spring support rods 204 are evenly spaced between the mounting strip 203 and the clamping strip 201, and the two ends of the spring support rod 204 are respectively fixed to the mounting strip 203 and the clamping strip 201 by welding. The spring support rod 204 of this structure is an existing support rod structure that is reset by a spring after extension. The mounting strip 203 and the clamping strip 201 are connected by the spring support rod 204, so that the clamping strip 201 can be elastically supported by the spring support rod 204 under the positioning of the mounting strip 203. The mounting strip 203 makes the clamping strip 201 stable relative to the movable traction roller 2, and the movable traction roller 2 is sleeved with springs at both ends. There is a fixed sleeve 202, which has a conical circular hole, and the fixed sleeve 202 is sleeved on the outside of the pressure strip 201. This structure can control the degree of compression of the pressure strip 201 by adjusting the contact position between the conical hole structure of the fixed sleeve 202 and the end of the pressure strip 201. By applying an initial force to the pressure strip 201, the pressure strip 201 is always in a compressed state, so that the pressure strip 201 cooperates with the fixed traction roller 3 to achieve a tightening clamping process and ensure a consistent clamping force, so that the polymer material is pulled with a consistent thickness and wrinkles are prevented. The fixed sleeve 202 is fixed to the movable traction roller 2 by screws, and an arc-shaped support plate 301 is provided under the fixed traction roller 3. The cross-section of the arc-shaped support plate 301 is a semicircular arc structure, and the arc The center of the support plate 301 is in the same straight line as the center of the fixed traction roller 3. This structure enables the arc-shaped support plate 301 to rotationally support the fixed traction roller 3 through the ball 303, so that the fixed traction roller 3 is evenly stressed, and the fixed traction roller 3 is prevented from bending and affecting the traction of the polymer material. The ball 303 is installed in the arc-shaped support plate 301, and the ball 303 is in contact with the fixed traction roller 3. The traction device body 1 is provided with a mounting frame 5, and the side fixing seats 4 are symmetrically welded on both sides of the upper end of the mounting frame 5. Reinforcement rods 302 are fixed between the side fixing seats 4 by welding, and the reinforcement rods 302 are bolted to the arc-shaped support plate 301. The side fixing seats 4 of this structure are used for the installation and fixing of the movable traction roller 2 and the fixed traction roller 3.The movable traction roller 2 and the fixed traction roller 3 can be clamped and rotated.

The fixing frames 7 are welded and fixed on both sides above the fixing box 6, and guide rollers 11 are installed between the fixing frames 7 through rotating shafts. This structure makes the fixing box 6 stable relative to the mounting frame 5 through the fixing plate 8, so that the guide roller 11 can guide the film.

The fixed frame 7 installs the guide roller 11 above the fixed box 6. When the film is between the guide roller 11 and the movable traction roller 2, the air pump 10 introduces the compressed gas into the fixed box 6 through the connecting pipe 9, and then blows air obliquely upward from the exhaust port 12 to provide the film with air flow support below, so that the film can be stretched flat, so that the film can pass smoothly between the movable traction roller 2 and the fixed traction roller 3 to prevent wrinkles. The fixed plate 8 makes the fixed box 6 be obliquely installed on the mounting frame 5, and the movable traction roller 2 and the fixed traction roller 3 pass through the fixed box 6. The side fixing seat 4 is fixed, and the movable traction roller 2 and the fixed traction roller 3 are rotated and pulled under the drive of the motor. The fixed sleeve 202 is sleeved on both ends of the movable traction roller 2 to fix the pressure strip 201, and by pressing the pressure strip 201 downward, the pressure strip 201 compresses the spring support rod 204 to have a certain pressure. At the same time, the fixed traction roller 3 is supported by the arc support plate 301 and the reinforcement rod 302 below, and the fixed traction roller 3 is rotationally supported by the ball 303, so that the pressure strip 201 cooperates with the fixed traction roller 3 to clamp the polymer material tightly and ensure the clamping force is consistent to prevent wrinkles. The installation strip 203 makes the pressure strip 201 firmly installed relative to the movable traction roller 2, thereby completing a series of tasks.
