[0032] See also Figure 1-9The utility model provides a film trimming device, including an operating table 100, wherein both sides of the top surface of the operating table 100 are respectively provided with a plurality of evenly distributed V-shaped grooves 103, a rotating tube 101 is arranged above the operating table 100, and the outer wall of the rotating tube 101 is provided with a plurality of circumferentially distributed side openings 200, and there are four side openings 200, and a fixed frame 201 is movably engaged with both sides of the plurality of side openings 201, and an annular cutter 102 is fixed to the outer wall of the fixed frame 201, and a fixed column 202 is fixed to the middle part of the inner wall of the rotating tube 101, and a first bidirectional threaded rod 203 is rotatably connected to the middle part of one side of the fixed column 202, and both sides of the first bidirectional threaded rod 203 are respectively and correspondingly movably connected to the fixed frame 201, and a hand wheel 204 is fixed to one end of the first bidirectional threaded rod 203.

[0033] Further as Figure 1 , Figure 5 and Figure 6 As shown, two opposite side surfaces of the outer wall of the operating table 100 are respectively provided with T-slots 402, and rectangular grooves 403 are respectively provided on both sides of the top surface of the inner wall of the T-slot 402, and limiting rings 300 are respectively provided on both sides of the outer wall of the rotating tube 101, and a rotating ring 301 is rotatably connected inside the limiting ring 300, and the inner wall of the rotating ring 301 is fixed to the outer wall of the rotating tube 101, and a T-bar 400 is fixed to the bottom of the outer wall of the limiting ring 300, and the T-bar 400 is correspondingly and movably engaged in the T-slot 402.

[0034] By setting the limiting ring 300, the rotating ring 301 can rotate inside the limiting ring 300, thereby causing the rotating tube 101 to rotate. By setting the T-bar 400 and the T-slot 402, the position of the limiting ring 300 can be movably limited on the operating table 100, so that the position of the limiting ring 300 can be adjusted easily.

[0035] This solution has the following working process: when trimming the film, first pull one end of the film roll between the two plug posts 601, then move the rotating tube 101 to a position close to the film roll, and then move the rotating tube 101 upward so that the two T-shaped rods 400 are respectively located at the top of the rectangular groove 403. At this time, the outer wall of the rotating tube 101 does not contact the top surface of the operating table 100, and then evenly pull the film and pass it through the bottom of the rotating tube 101 so that the film is evenly spread on the top surface of the operating table 100, and then release the restriction on the rotating tube 101, and at the same time move the rotating tube 101 downward. Tube 101, at this time, the outer wall of the rotating tube 101 contacts the surface of the film, and then the pull rod 302 is pulled, the rotating tube 101 moves on the surface of the film, the annular cutter 102 is opposite to the V-shaped groove 103, and the annular cutter 102 cuts the film in the V-shaped groove 103, so that the edge of the film is cut, and when the T-bar 400 moves to the position of the rectangular groove 403 away from the side of the film roll, the trimmed film is cut from the film roll, and then the rotating tube 101 is moved up so that the T-bar 400 is located in the rectangular groove 403, one end of the film is pulled, and then the trimmed film can be taken out.

[0036] When adjusting the spacing between the two annular cutters 102, first move the T-bar 400 into the rectangular groove 403 so that the rotating tube 101 does not contact the top surface of the operating table 100, and then manually rotate the hand wheel 204. The rotation of the hand wheel 204 drives the first bidirectional threaded rod 203 to rotate. The rotation of the first bidirectional threaded rod 203 drives the fixed frame 201 to move closer to or away from each other, so that the spacing between the two annular cutters 102 can be adjusted. The adjusted annular cutter 102 still needs to be opposite to the V-groove 103.

[0037] When fixing film rolls of different widths, first rotate the cross rotating knob 504. The rotation of the cross rotating knob 504 drives the second bidirectional threaded rod 502 to rotate. The rotation of the second bidirectional threaded rod 502 drives the moving rods 503 on both sides to move, so that the spacing between the moving rods 503 on both sides reaches the maximum. Then, the film is rolled between the two pins 601, and the cross rotating knob 504 is manually rotated in the opposite direction to make the two moving rods 503 close to each other. Finally, the two pins 601 are respectively engaged with the two sides of the film roll to limit the position of the film roll.

[0038] According to the above working process, it can be known that: by means of the setting of the limiting ring 300 and the rotating ring 301, the rotating tube 101 can roll on the top surface of the operating table 100, and by means of the setting of the annular cutter 102, the annular cutter 102 can trim the film when the rotating tube 101 rolls, and by means of the setting of the V-shaped groove 103, the film can be cut in the V-shaped groove 103, thereby avoiding the situation where the surface of the operating table 100 is scratched and burred, and the bottom surface of the film is intact after cutting, thereby improving the quality of the film after trimming.

[0039] By providing the first bidirectional threaded rod 203 and the fixing frame 201, the distance between the two annular cutters 102 can be adjusted, so that films of different widths can be trimmed, thereby improving the applicability of the trimming device.

[0040] By providing the second bidirectional threaded rod 502 and the movable rod 503, the distance between the two plug posts 601 can be adjusted, so that film rolls of different widths can be fixed, further improving the applicability of the trimming device.

[0041] Further as Figure 1 and Figure 2 As shown, a symmetrically distributed mounting strip 602 is fixed to one side of the operating table 100, and a limit frame 500 is fixed at one end of two mounting strips 602. Positioning posts 501 distributed up and down are fixed between the two opposite sides of the inner wall of the limit frame 500, and moving rods 503 are movably connected to the two outer sides of the two positioning posts 501 respectively. A second bidirectional threaded rod 502 is rotatably connected between the two opposite side surfaces of the inner wall of the limit frame 500, and the two sides of the second bidirectional threaded rod 502 are movably connected to the moving rod 503 respectively, and a cross rotating button 504 is fixed to one end of the second bidirectional threaded rod 502.

[0042] By providing the second bidirectional threaded rod 502 , the moving rods 503 on both sides can move closer to or farther away from each other, thereby driving the plug posts 601 to move closer to or farther away from each other, so that film rolls of different widths can be restricted.

[0043] Further as Figure 2 As shown, a fixing plate 600 is fixed to the top of a side surface of the two moving rods 503 close to each other, and a plug post 601 is fixed to the center of a side surface of the two fixing plates 600 close to each other.

[0044] By providing the pins 601, the position of the film roll can be limited.

[0045] Further as Figure 5 As shown, a pull rod 302 is fixed at a lateral position on the outer side walls of the two limiting rings 300 .

[0046] The pull rod 302 is provided to facilitate the movement of the rotating tube 101, thereby facilitating the annular cutter 102 to cut the film.

[0047] Further as Figure 5 As shown, a connecting rod 401 is fixed between the bottom surfaces of the two T-shaped rods 400 .

[0048] The connection between the two limiting rings 300 is made more stable by the provided connecting rod 401 .

[0049] In summary: when trimming the film, first pull one end of the film roll between the two plug posts 601, then move the rotating tube 101 to a position close to the film roll, and then move the rotating tube 101 upward so that the two T-shaped rods 400 are respectively located at the top of the rectangular groove 403. At this time, the outer wall of the rotating tube 101 does not contact the top surface of the operating table 100, and then evenly pull the film and pass it through the bottom of the rotating tube 101 so that the film is evenly spread on the top surface of the operating table 100, and then release the restriction on the rotating tube 101, and at the same time move the rotating tube 101 downward. At this time, the outer wall of the rotating tube 101 contacts the surface of the film, and then the pull rod 302 is pulled, the rotating tube 101 moves on the surface of the film, the annular cutter 102 is opposite to the V-shaped groove 103, and the annular cutter 102 cuts the film in the V-shaped groove 103, so that the edge of the film is cut, and when the T-bar 400 moves to the position of the rectangular groove 403 away from the side of the film roll, the trimmed film is cut from the film roll, and then the rotating tube 101 is moved upward so that the T-bar 400 is located in the rectangular groove 403, one end of the film is pulled, and then the trimmed film can be taken out.

[0050] When adjusting the spacing between the two annular cutters 102, first move the T-bar 400 into the rectangular groove 403 so that the rotating tube 101 does not contact the top surface of the operating table 100, and then manually rotate the hand wheel 204. The rotation of the hand wheel 204 drives the first bidirectional threaded rod 203 to rotate. The rotation of the first bidirectional threaded rod 203 drives the fixed frame 201 to move closer to or away from each other, so that the spacing between the two annular cutters 102 can be adjusted. The adjusted annular cutter 102 still needs to be opposite to the V-groove 103.

[0051] When fixing film rolls of different widths, first rotate the cross rotating knob 504. The rotation of the cross rotating knob 504 drives the second bidirectional threaded rod 502 to rotate. The rotation of the second bidirectional threaded rod 502 drives the moving rods 503 on both sides to move, so that the spacing between the moving rods 503 on both sides reaches the maximum. Then, the film is rolled between the two pins 601, and the cross rotating knob 504 is manually rotated in the opposite direction to make the two moving rods 503 close to each other. Finally, the two pins 601 are respectively engaged with the two sides of the film roll to limit the position of the film roll.

[0052] The annular cutter 102 can be purchased from the market, and is a mature technology in the art, which has been fully disclosed, and therefore will not be repeated in the specification.
