Detailed implementation manners

[0037] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0038] Below in conjunction with Figure 1 -8, the detailed implementation manners of the present invention will be described. An automated horizontal cutting device for medical films includes a support bracket 1, and the support bracket 1 is fixedly installed at the end of the device for producing medical films;

[0039] A conveying mechanism 2, and the conveying mechanism 2 is installed on the front side of the support bracket 1;

[0040] An electrostatic emitter 3, and the electrostatic emitter 3 is fixedly located below the conveying mechanism 2 and fixedly installed on the support bracket 1;

[0041] A lifting component 4, the lifting component 4 is slidably connected to the support bracket 1 and a telescopic cylinder 5 is provided between it and the support bracket 1, and a cutting knife 9 is installed on the lower side of the lifting component 4;

[0042] And a guiding component 6, the guiding component 6 is slidably connected to the rear side of the support bracket 1 and is connected to the lifting component 4 through a connecting rod 11.

[0043] By setting up the electrostatic emitter 3 to generate static electricity, which is attached to the conveying mechanism 2, the film is adsorbed on the conveying mechanism 2 by the electrostatic adsorption force. After reaching the set length, the conveyance of the conveying mechanism 2 is stopped. By virtue of the continuous output of the film in the production device, the film deforms under the lower side of the cutting knife 9. The cutting knife 9 is driven to move to the cutting position by driving the telescopic cylinder 5. During the elongation of the telescopic cylinder 5, the guiding component 6 is pushed to move by the connecting rod 11. Compared with the traditional device with such a setting, this device can cut the deformed film during the process of its rebound, thus effectively avoiding the phenomenon of the cutting knife slipping due to the smooth surface of the film. At the same time, by using the principle of electrostatic adsorption, it is avoided that the bracket exerts force on the surface of the film and leaves slip marks on the film.

[0044] Preferably, in a specific embodiment of the present invention, referring again to Figure 1 -8, an adjusting component 10 is further arranged on the upper side of the conveying mechanism 2. The adjusting component 10 is slidably installed on the support bracket 1, and its lower part is attached to the surface of the conveying mechanism 2. An infrared sensing device is also installed on the adjusting component 10, and the infrared sensing device is in signal connection with the telescopic cylinder 5. A driving device is installed on the conveying mechanism 2, and the driving device is in signal connection with the infrared sensing device.

[0045] Under the action of the electrostatic force, the film adheres to the conveying mechanism 2. As the conveying mechanism 2 moves, the film comes into contact with the adjusting component 10. Since the infrared sensing device is installed on the adjusting component 10, after sensing the film, it will transmit an electrical signal to the telescopic cylinder 5 and stop the rotation of the driving device.

[0046] Preferably, in a specific embodiment of the present invention, referring again to Figure 1 -8, the adjusting component 10 includes an adjusting baffle 1001. Both sides of the adjusting baffle 1001 are slidably connected with adjusting sliding frames 1003. Both ends of the adjusting baffle 1001 are fixedly connected with lead screws 1002. The two lead screws 1002 respectively pass through the two adjusting sliding frames 1003 and are threadedly connected with the two adjusting sleeves 1004. The two adjusting sleeves 1004 are respectively rotatably connected with the two adjusting sliding frames 1003.

[0047] When adjusting the size of the film to be intercepted, by rotating the adjusting sleeve 1004 and using the threaded connection with the lead screw 1002, the adjusting sliding frame 1003 slidably installed on the adjusting baffle 1001 is pushed to move towards the middle. Since the adjusting baffle 1001 and the adjusting sliding frame 1003 are respectively arranged inside and outside the support bracket 1, when the adjusting sliding frame 1003 moves inwards, it will clamp on both sides of the support bracket 1, thereby fixing its position.

[0048] Preferably, in a specific embodiment of the present invention, referring again to Figure 1 -8, a knife sheath 8 is provided below the lifting assembly 4. The knife sheath 8 is fixedly installed on the support bracket 1. The cutting knife 9 is slidably disposed in the knife sheath 8. The knife sheath 8 is provided with a through hole, and the distance between the lowermost end of the knife sheath 8 and the conveying mechanism 2 is exactly equal to the thickness of the film.

[0049] When the end of the film contacts the adjusting assembly 10 and is restricted by the adjusting assembly 10, since the medical film production device does not stop production, the film will be deformed under the thrust (the thrust generated at the outlet of the film production device). By providing the knife sheath 8 on the support bracket 1, the distance between the knife sheath 8 and the conveying mechanism 2 is exactly the thickness of the film. Therefore, under the action of the knife sheath 8, the film can only be deformed to the side away from the cutting knife 9.

[0050] Preferably, in a specific embodiment of the present invention, referring again to Figure 1 -8, the lifting assembly 4 includes a first lifting bracket 401 and a second lifting bracket 402. The first lifting bracket 401 and the second lifting bracket 402 are slidably connected to each other and a first elastic member 403 is disposed between them. The telescopic end of the telescopic cylinder 5 is fixedly connected to the first lifting bracket 401. One side of the connecting rod 11 is rotatably connected to the first lifting bracket 401. The cutting knife 9 is fixedly connected to the lower part of the second lifting bracket 402.

[0051] When the telescopic cylinder 5 extends, it will push the lifting assembly 4 to move downward, and the cutting knife 9 fixed to the lower part of the lifting assembly 4 is used to cut the film. When the second lifting bracket 402 moves to the lowermost end (the cutting edge of the cutting knife 9 just coincides with the upper surface of the conveying mechanism 2), under the continuous extension of the telescopic cylinder 5, a movement occurs between the first lifting bracket 401 and the second lifting bracket 402. The first lifting bracket 401 continues to move downward, and the guiding assembly 6 is pushed to move toward the film production device by the connecting rod 11, thereby stretching the deformed film to a flat state. During this process, since the cutting edge of the cutting knife 9 just coincides with the upper surface of the conveying mechanism 2, the film will use the pulling force on both sides of the stretched and tiled film to act on the cutting edge of the cutting knife 9, thereby completing the cutting of the film.

[0052] Preferably, in a specific embodiment of the present invention, referring again to Figure 1-8, the guiding assembly 6 includes a guiding bracket 601 and guiding rollers 602. There are two guiding brackets 601 which are respectively slidably connected to both sides of the supporting bracket 1. One end of the connecting rod 11 is rotatably connected to the guiding bracket 601. There are two guiding rollers 602. On both sides of each guiding roller 602, there are only convex platforms 603. Both guiding rollers 602 are slidably connected to the slot holes on the two guiding roller carriages by the convex platforms 603 on both sides; the convex platforms 603 extend outwards after passing through the guiding bracket 601, and the ends of the convex platforms 603 are on the same horizontal line as the side edges of the clamping bracket 7 connected to the supporting bracket 1.

[0053] By setting the clamping bracket 7, during the movement of the guiding assembly 6, the convex platforms 603 extending outside act on the clamping bracket 7, so that the two guiding rollers 602 act on the film, and press on both sides of the film.

[0054] Preferably, in a specific embodiment of the present invention, refer to again Figure 1 -8, between the two guiding rollers 602, there are two elastic components 604. The two elastic components 604 are respectively arranged on the two guiding brackets 601. Both sides of the elastic component 604 act on the convex platforms 603 of the two guiding rollers 602 respectively.

[0055] The setting of the elastic component can make the guiding rollers 602 distributed on both sides of the film when the guiding assembly 6 does not move, so that the guiding rollers 602 can only play a guiding role; at the same time, the positions of the two guiding rollers 602 can be restored during the leftward movement of the guiding assembly 6.

[0056] Preferably, in a specific embodiment of the present invention, refer to again Figure 1 -8, the clamping bracket 7 is set in a U shape. The two outer edges of the U shape of the clamping bracket 7 are slidably connected to the supporting bracket 1. A second elastic member is arranged between the arc end of the clamping bracket 7 and the supporting bracket 1. The convex platform 603 is tangent to the inner edge of the U-shaped structure on the clamping bracket 7.

[0057] The produced film passes through the two guiding rollers 602. When the connecting rod 11 pushes the guiding bracket 601, the U-shaped structure of the clamping bracket 7 is used to make the convex platform 603 act on the inner side of the U-shaped structure, and then push the two guiding rollers 602 to move towards the middle, and apply force on both sides of the film; by setting the second elastic member, the clamping bracket 7 can move following the guiding assembly 6 after the guiding assembly 6 applies pressure to the film.

[0058] Preferably, in a specific embodiment of the present invention, refer to again Figure 1-8, the device further includes a collection mechanism 12, which is fixedly installed on the ground or the support bracket 1 by a robotic arm. A suction cup assembly is installed on the lower side of the collection mechanism 12. The suction cup assembly consists of a fixed collection suction cup 1203 and a telescopic collection suction cup 1203. The fixed collection suction cup 1203 is connected to the collection bracket 1201, and the telescopic collection suction cup 1203 is connected to the collection bracket 1201 through a telescopic rod 1204. An elongation elastic member is sleeved outside the telescopic rod 1204 to keep the telescopic rod 1204 in an extended state under natural conditions.

[0059] After the film is cut, the collection mechanism 12 is moved to the upper side of the film by driving the robotic arm. After all the collection suction cups 1203 on the collection mechanism 12 come into contact with the film, the film is adsorbed by using a vacuum machine, and then the film is collected into the collection rack by driving the robotic arm. By arranging the collection suction cups 1203 on the lower side of the telescopic rod 1204, in the process of raising the collection mechanism 12, the four corners of the film can be lifted first, and finally, after the telescopic rod 1204 extends to the limit position, the middle part of the film leaves the conveying mechanism 2. This arrangement can prevent air from entering the middle part of the film under the action of the electrostatic force of the conveying mechanism 2 during the process of the collection mechanism 12 collecting the film, and the four corners of the film will gather towards the middle, preventing scratches on the film caused by friction between the film and the conveying mechanism 2.

[0060] Preferably, in a specific embodiment of the present invention, referring again to Figure 1 -8, a collection sliding frame 1202 is sleeved on the collection bracket 1201. Rotating rods 1205 are rotatably connected to both sides of the collection sliding frame 1202. The fixed self-suction cup is fixedly installed at the swinging end of the rotating rod 1205. An angle self-locking device 1206 is arranged at the connection between the rotating rod 1205 and the collection sliding frame 1202. A bolt is arranged on the collection sliding frame 1202 for fixing the position of the collection sliding frame 1202.

[0061] During use, the collection sliding frame 1202 can be moved and the rotating rod 1205 can be rotated according to the size of the film to adjust to match the size of the film. The self-locking device 1206 and the bolt can fix the positions of the collection sliding frame 1202 and the rotating rod 1205 after adjusting their positions.

[0062] The working principle of an automated medical film cross-cutting device of the present invention is as follows:

[0063] During use, first, when adjusting the size of the film to be intercepted, by rotating the adjusting sleeve 1004 and using the threaded connection with the lead screw 1002, the adjusting carriage 1003 slidably mounted on the adjusting baffle 1001 is pushed to move towards the middle. Since the adjusting baffle 1001 and the adjusting carriage 1003 are respectively arranged on the inner and outer sides of the support bracket 1, when the adjusting carriage 1003 moves inward, it will be clamped on both sides of the support bracket 1, thereby fixing its position.

[0064] Then, an electrostatic emitter 3 is set to generate static electricity and attach it to the conveying mechanism 2. The film is adsorbed on the conveying mechanism 2 by the electrostatic adsorption force. Under the action of the electrostatic force, the film adheres to the conveying mechanism 2. As the conveying mechanism 2 moves, the film contacts the adjusting component 10. Since an infrared sensing device is installed on the adjusting component 10, after sensing the film, it will transmit an electrical signal to the telescopic cylinder 5 and stop the rotation of the driving device. Due to the continuous output of the film in the production device, the film deforms under the lower side of the cutting knife 9. The extension of the telescopic cylinder 5 will push the lifting component 4 to move downward. The cutting knife 9 fixed to the lower part of the lifting component 4 cuts the film. When the second lifting bracket 402 moves to the lowest end (the cutting edge of the cutting knife 9 just coincides with the upper surface of the conveying mechanism 2), under the continuous extension of the telescopic cylinder 5, a movement occurs between the first lifting bracket 401 and the second lifting bracket 402. The first lifting bracket 401 continues to move downward, and the connecting rod 11 is used to push the guiding component 6 to move towards one side of the film production device, so that the convex platform 603 acts on the inner side of the U-shaped structure, and then two guiding rollers 602 are pushed to move towards the middle, applying force to both sides of the film; driving the film to rebound, the deformed film can act on the cutting knife during the rebounding process for cutting, thereby effectively avoiding the phenomenon of the cutting knife slipping due to the smooth surface of the film; after cutting, the film on the conveying mechanism 2 is taken away by the suction cup (the suction cup is equipped with an anti-static device).

[0065] The present invention is not limited to the above optional embodiments. Anyone can obtain other various forms of products under the inspiration of the present invention. However, no matter what changes are made in its shape or structure, as long as the technical solutions fall within the scope defined by the claims of the present invention, they are all within the protection scope of the present invention.
