[0009] In a preferred embodiment of a medical film flattening and crease removal device, the square groove arms are provided in five numbers and are rotatably arranged on a circular frame, and a cutter head is arranged in the cutting press head.

[0010] In a preferred embodiment of a medical film flattening and crease removal device, the shaft between the six-sided flattening arm and the transposition wheel is rotatably connected to the front side frame of the return frame through a bearing, the six-sided flattening arm is respectively located on both sides of the front side frame of the return frame, and the transposition wheel and the incomplete wheel are on the same vertical plane.

At this time, the second gear and the two feed flattening rollers on the first gear are in a flattening and de-crease structure that presses the medical film against the resistance roller.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: when the present invention is used, the medical film is first adsorbed on the side unfolding plane of the six-sided flattening arm through the negative pressure adsorption pores, and the six-sided flattening arm rotates counterclockwise, and the six-sided flattening arm pulls the medical film and wraps it on the arm body of the six-sided flattening arm. In this way, the pulling, flattening and crease removal processing of the medical film on each unfolding plane of the six-sided flattening arm is achieved. At the same time, through this direct flattening on the unfolding plane, it is also convenient for the subsequent downward movement and slitting of the cutting pressure head. At the same time, when the six-sided flattening arm rotates, a plurality of flattening and crease removal rollers form a rolling structure that rotates in the opposite direction on the top and bottom unfolding planes of the six-sided flattening arm. This kind of follow-up reverse rolling performs follow-up reverse rolling processing on the medical film on the top and side surfaces of the six-sided flattening arm, that is, realizes secondary follow-up reverse rolling flattening and crease removal processing of the medical film, and at the same time, the flattening and crease removal roller elastically contacts the six-sided flattening arm through the second tensioning spring and the first tensioning spring. Through this elastic resistance, on the one hand, the reliability of the flattening and crease removal roller contacting each surface of the six-sided flattening arm is guaranteed, and on the other hand, when the six-sided flattening arm rotates and the edges and corners of the six-sided flattening arm rotate, the flattening and crease removal roller can retreat and avoid well to avoid affecting the smooth rotation of the six-sided flattening arm. A flattening auxiliary feeding roller assembly is arranged on one side of the flattening machine base assembly of the present invention. The two feed flattening rollers on the second gear and the first gear are in a flattening and crease-removing structure for the medical film by means of the resistance roller pressure. That is, in actual use, the medical film is first passed through the two feed flattening rollers and then adsorbed and adhered to the flattening arm assembly. In this way, the double-sided resistance roller pressure flattening and crease-removing processing of the medical film at the material inlet is achieved. At the same time, in actual use, the two feed flattening rollers are arranged on a seat groove frame, and the seat groove frame is elastically arranged on one side of the flattening machine seat assembly through the second resistance spring and the first resistance spring. Since the force of the first resistance spring is greater than the force of the second resistance spring, the two feed flattening rollers form a downward resistance structure at the six-sided flattening arm loading port at this time. With this structural arrangement, when there is loose medical film at the feeding port of the flattening arm assembly, the downward resistance structure can ensure that the medical film always maintains a certain tension, thereby ensuring the flattening effect of the medical film when it is wrapped and laid flat by the six-sided flattening arm. In the present invention, when the six-sided flattening arm drives the conductive contact to rotate to the opening at the lower end of the C-shaped conductive contact, the conductive contact and the C-shaped conductive contact are not electrically connected, and the corresponding air pump is not started, that is, the negative pressure adsorption pores on the lowest expansion plane of the six-sided flattening arm do not form a negative pressure adsorption structure. At this time, the medical film on the lowest expansion plane of the six-sided flattening arm forms an automatic lower film falling structure, thereby facilitating the lower film after the medical film is cut.

The second gear 308 and the first gear 307 are rotatably arranged on the front end surface of the seat slot frame 301. The gear shaft 309 of the second gear 308 is coaxially fixed with a friction gear 312. The second gear 308 and the first gear 307 are both fixedly arranged with a gear side arm 311. The feed flattening roller 310 is rotatably arranged at the far end of the gear side arm 311. The end fixing plate 313 at the bottom of the guide slide bar 315 is fixed on the top of the side support rod 119. The first and second springs 314 and 316 are respectively located at the top and bottom of the grooved back plate 317. Through the tightening of the first spring 314 and the second spring 316, the seat slot frame 301 elastically slides on the guide slide bar 315. The force of the contact spring 314 is greater than the force of the second resistance spring 316, the first gear 307 and the second gear 308 are meshed, the vertical tooth arm 306 and the resistance gear 312 are meshed, and the vertical tooth arm 306 is pushed by the push spring 303. At this time, the vertical tooth arm 306 drives the resistance gear 312 to rotate counterclockwise. At this time, the second gear 308 and the two feed flattening rollers 310 on the first gear 307 are in a flattening and de-crease structure for the medical film resistance roller pressure.

[0030] The working principle of the present invention is as follows: when the present invention is used, the medical film wound on the winding roller first passes through the flattening auxiliary feeding roller assembly 300 and then is adsorbed on the negative pressure adsorption pores 205 on the flattening arm assembly 200. At this time, the rotation of the six-sided flattening arm 201 drives the film to be flattened on each surface of the six-sided flattening arm 201. When it rotates to the top position, the cutting pressure head 111 is driven by the cylinder 110 to move down and press against the two sides of the top flattening plane of the six-sided flattening arm 201, thereby realizing the slitting of the medical film on the top flattening plane, that is, the medical film is slid and trimmed. It should be noted that the medical film is adsorbed on each flattening plane of the six-sided flattening arm 201 through the negative pressure adsorption pores 205. At this time, the air pump 20 A negative pressure structure is formed on each unfolding plane through the air chamber 207 and the negative pressure adsorption air hole 205. At this time, the medical film can be adsorbed on each unfolding plane through the negative pressure adsorption air hole 205. It should be noted that when the medical film is cut, the medical film is first adsorbed on the side unfolding plane of the six-sided flattening arm 201 through the negative pressure adsorption air hole 205. Through the counterclockwise rotation of the six-sided flattening arm 201, the six-sided flattening arm 201 pulls the medical film and wraps it on the arm body of the six-sided flattening arm 201. In this way, the pulling, flattening and crease removal of the medical film on each unfolding plane of the six-sided flattening arm 201 is achieved. At the same time, through this direct flattening on the unfolding plane, it is also convenient for the subsequent downward movement of the cutting pressure head 111 for cutting.

[0031] On the basis of the above, when the six-sided flattening arm 201 rotates and pulls and flattens the medical film, since the top and side surfaces of the six-sided flattening arm 201 are pressed and resisted by the second tensioning spring 115 and the first tensioning spring 113, the flattening and de-crease rollers 112 are provided. At this time, through the resistance between the flattening and de-crease rollers 112 and the six-sided flattening arm 201, when the six-sided flattening arm 201 rotates, a plurality of flattening and de-crease rollers 112 form a rolling structure that rotates in the opposite direction on the top and bottom flattening planes of the six-sided flattening arm 201. Through this kind of follow-up reverse rolling, the medical film on the top and side surfaces of the six-sided flattening arm 201 is flattened. The film is subjected to a follow-up reverse rolling process, that is, a secondary follow-up reverse rolling flattening and crease removal process of the medical film is achieved. At the same time, the flattening and crease removal roller 112 is elastically abutted against the six-sided flattening arm 201 through the second tensioning spring 115 and the first tensioning spring 113. Through this elastic abutment, on the one hand, the reliability of the flattening and crease removal roller 112 abutting against each surface of the six-sided flattening arm 201 is guaranteed. On the other hand, when the six-sided flattening arm 201 rotates and when the edges and corners of the six-sided flattening arm 201 rotate, the flattening and crease removal roller 112 can retreat and avoid affecting the smooth rotation of the six-sided flattening arm 201.

[0032] On the basis of the above, the driving motor 104 of the present invention drives the incomplete wheel 105 to rotate. At this time, the incomplete wheel 105 drives the toggle rod 102 on the toggle arm 103 to rotate, and cooperates with the limit groove 203 and the transposition groove 204 on the transposition wheel 202. When the incomplete wheel 105 rotates one circle, the toggle rod 102 at the end of the toggle arm 103 intermittently toggles the transposition wheel 202 through the transposition groove 204. That is, in this way, the intermittent rotation of the six-sided flattening arm 201 on the flattening machine base assembly 100 is realized. In this way, when the flattening plane on the side of the six-sided flattening arm 201 rotates to the top, it can stop. At this time, the cylinder 110 can be started to drive the cutting pressure head 111 to move down to press and cut. In this way, the high coordination of the flattening and cutting actions of the device is guaranteed.

[0033] On the basis of the above, a flattening auxiliary feed roller assembly 300 is provided on one side of the flattening machine base assembly 100 of the present invention. When in use, the first gear 307 and the second gear 308 are meshed, and the vertical tooth arm 306 and the resistance gear 312 are meshed. Through the pushing force of the pushing spring 303 on the vertical tooth arm 306, the vertical tooth arm 306 drives the resistance gear 312 to rotate counterclockwise. At this time, the second gear 308 and the two feed flattening rollers 310 on the first gear 307 are in a flattening and de-crease structure for the medical film resistance roller pressure. That is, in actual use, the medical film is first passed through the two feed flattening rollers 310 and then adsorbed and adhered to the flattening arm assembly 200. In this way, the double-sided resistance of the medical film at the material inlet is achieved. The contact roller is used for flattening and crease removal. In actual use, two feed flattening rollers 310 are arranged on the seat groove frame 301. The seat groove frame 301 is elastically arranged on one side of the flattening machine base assembly 100 through the second resistance spring 316 and the first resistance spring 314. Since the force of the first resistance spring 314 is greater than the force of the second resistance spring 316, the two feed flattening rollers 310 form a downward resistance structure at the feeding port of the six-sided flattening arm 201. Through this structural setting, when there is loose medical film at the feeding port of the flattening arm assembly 200, the downward resistance structure can ensure that the medical film always maintains a certain tension, thereby ensuring the flattening effect of the medical film when it is wrapped and flattened by the six-sided flattening arm 201.

[0034] On the basis of the above, when the six-sided flattening arm 201 of the present invention rotates, the elastic telescopic rod 208 at the bottom of the air pump 206 drives the conductive contact 209 to make electrical contact with the outside of the C-shaped conductive contact 118. At this time, the air pump 206 is started, that is, the negative pressure adsorption pores 205 on the top and side display platforms of the six-sided flattening arm 201 form a negative pressure adsorption structure. When the six-sided flattening arm 201 drives the conductive contact 209 to rotate to the opening at the lower end of the C-shaped conductive contact 118, the conductive contact 209 and the C-shaped conductive contact 118 are not electrically connected. At this time, the corresponding air pump 206 is not started, that is, the negative pressure adsorption pores 205 on the lowest display plane of the six-sided flattening arm 201 do not form a negative pressure adsorption structure. At this time, the medical film on the lowest display plane of the six-sided flattening arm 201 forms an automatic lower film falling structure, thereby facilitating the lower film after the medical film is cut.
