The guide rollers 200 are used to guide the PE film. The PE film is transmitted along the direction of the guide rollers 200, the film pulling component 300 and the guide rollers 200, and the film pulling component 300 provides power to pull the PE film; wherein, the film pulling component 300 includes a pulling roller 301 and a supporting seat 302 provided at both ends of the pulling roller 301, one of the supporting seats 302 is provided with a retractable bearing seat 303 on the side facing the pulling roller 301, and the bearing seat 303 is used for pulling the roller The traction roller 301 is plugged in and positioned at one end, and the outer wall of the other supporting seat 302 is fixedly connected with a traction motor 318 for driving the traction roller 301 to rotate. The traction roller 301 is connected to the rotating shaft of the traction motor 318 by an interlaced card connection, so that the traction motor 318 can drive the traction roller 301 to rotate while the traction roller 301 can be separated from the traction motor 318 by a transverse movement. Then, the retractable and movable bearing seat 303 configured on the other supporting seat 302 is interlaced and carded with the other end of the traction roller 301, and the connection or separation with one end of the traction roller 301 can be achieved by moving the bearing seat 303. In this way, there is no need to disassemble the entire supporting seat 302, making the disassembly and assembly of the traction roller 301 more convenient and efficient.

[0023] It should be noted that the end of the bearing seat 303 facing away from the traction roller 301 is fixedly connected to the polygonal column 307, and the outer wall of the polygonal column 307 is movably plugged into the middle of the bearing seat 302. The polygonal column 307 and the bearing seat 302 are movably interlaced, so that the bearing seat 303 can be limited to move laterally. The traction roller 301 is fixedly connected to the polygonal shaft 305 at one end facing the bearing seat 303. A sleeve 306 is provided on the inner side of the bearing seat 303. A through groove matching the polygonal shaft 305 is provided in the middle of the sleeve 306. A ball bearing 304 is fixedly connected between the sleeve 306 and the bearing seat 303. The other end of the traction roller 301 is connected to the output shaft of the traction motor 318 through the ball bearing 304 in the bearing seat 303. The shaft sleeve 306, combined with the polygonal shaft 305 at one end of the traction roller 301, matches the shaft sleeve 306, so that the polygonal shaft 305 can keep the traction roller 301 rotatable after being inserted into the shaft sleeve 306, and the shaft sleeve 306 can also be withdrawn. A locking piece is provided between the bearing seat 302 and the polygonal column 307, and the locking piece is used to limit the fixation between the polygonal column 307 and the bearing seat 302. The setting of the locking piece enables the shaft sleeve 306 to reach the plug-in position with the polygonal shaft 305, and the position of the shaft sleeve 306 is restricted by locking and limiting the polygonal column 307 and the bearing seat 302, thereby achieving the support of the traction roller 301 and the polygonal shaft 305 at one end thereof, so that the traction roller 301 can maintain stable rotation.

When the pin 309 is inserted into the socket 310 of the polygonal column 307, the bearing seat 303 is in the installation position for the traction roller 301. When the traction roller 301 needs to be disassembled, it is only necessary to pull out the pin 309 so that the polygonal column 307 can move outward. In this way, the bearing seat 303 can be moved away from the traction roller 301, and the polygonal shaft 305 on the traction roller 301 can be pulled out from the shaft sleeve 306, so that the traction roller 301 can move horizontally for a distance, so that the other end of the traction roller 301 is separated from the output shaft of the traction motor 318, thereby achieving the purpose of disassembly.

[0025] The support frame 302 is fixed with a linear bearing 311 on both sides, and a column 312 is movably inserted into the inner side of the linear bearing 311. The bottom end of the column 312 is fixedly connected to the top of the support platform 100. The linear bearing 311 cooperates with the column 312 so that the support frame 302 can be lifted and lowered along the column 312. At the same time, the friction resistance of the linear bearing 311 is small. A support plate 313 is provided below the support frame 302, and an articulated seat 314 is hinged at both ends of the support plate 313. An outer shell 315 is provided below the traction roller 301, and a combination screw 316 is rotatably connected to the outer shell 315. The outer wall of the combination screw 316 is threadedly connected to two nut seats 317.

One end of the combination screw 316 can be manually driven by a turning handle, or it can be electrically driven by a servo motor. The combination screw 316 is spliced ​​by two screws with opposite thread directions. When the combination screw 316 rotates in one direction, it drives the two nut seats 317 to move synchronously toward each other or in opposite directions. In this way, the movement of the nut seat 317 can be used to drive the support plate 313 to move, thereby synchronously supporting or lowering the bearing seat 302, thereby achieving the adjustment of the height of the traction roller 301, so as to achieve the stability of the traction roller 301 in the traction process of the PE film.
