Specific embodiments

[0023] To make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand

[0024] and comprehend, the following combines specific embodiments to further elaborate the present utility model.

[0025] As Figure 1 shown, the present utility model provides a horizontal film slitting machine, including a box body base 1. A cutting mechanism 2 is arranged on the top of the box body base 1. A tension adjustment mechanism 4 is arranged on the front side of the cutting mechanism 2. A film positioning mechanism 3 is arranged on the front side of the tension adjustment mechanism 4.

At this time, the winding motor is started to carry out the film winding and striping work.

[0027] like Figure 2 、 Figure 3 As shown, the cutting mechanism 2 includes a door-shaped bracket 21, two vertical parts of the door-shaped bracket 21 are fixedly installed on the top of the box base 1, a servo motor 22 is fixedly installed on the left side of the left vertical part of the door-shaped bracket 21, the output shaft of the servo motor 22 passes through the right side of the left vertical part of the door-shaped bracket 21 and is fixedly installed with a driving gear 23, a supporting roller 24 is fixedly installed on the right side of the driving gear 23, a driven gear 25 is movably installed on the upper right side of the left vertical part of the door-shaped bracket 21, the driven gear 25 is meshed with the driving gear 23, and the driven gear 25 is meshed with the main gear 23. The front side of the driven gear 23 is provided with an inclined baffle, which is fixedly installed at the vertical position on the left side of the door-shaped bracket 21, and can shield the driven gear 25 and the driving gear 23 to prevent the film from being rolled in. The right side of the driven gear 25 is fixedly installed with an adjusting threaded rod 26, and the outer wall of the adjusting threaded rod 26 is evenly provided with a plurality of tool mechanisms 27. The plurality of tool mechanisms 27 are all located above the supporting roller 24, and the plurality of tool mechanisms 27 include a turntable 271. The outer wall of the plurality of turntables 271 is fixedly installed with a circular knife 272. 271 are all threadedly connected to the adjusting threaded rod 26, and a plurality of rotating disks 271 are movably installed with movable rings 273 on both sides, and a plurality of door-shaped hanging plates 274 are fixedly installed on the tops of the movable rings 273 on the left and right sides of the rotating disks 271. A sliding groove 211 is opened at the horizontal part of the door-shaped bracket 21, and a square sliding rod 212 is fixedly installed between the left and right sides of the inner wall of the sliding groove 211. A plurality of sliders 213 are slidably installed on the outer wall of the square sliding rod 212. The tops of the horizontal parts of the plurality of door-shaped hanging plates 274 are respectively connected to the bottoms of the plurality of sliders 213. Fixed connection, the top of the plurality of sliders 213 is provided with a positioning threaded hole 214 that passes through the inner circle thereof, and the inner circle thread of the positioning threaded hole 214 is threadedly installed with a fixing bolt 215, and the bottom end of the fixing bolt 215 is in contact with the top of the square slide bar 212, and pointers 216 are fixedly installed on the front upper side of the plurality of sliders 213, and the plurality of pointers 216 are all on the same vertical line with the blades of the plurality of circular knives 272, and a scale line 217 is fixedly painted on the top of the horizontal part of the door-shaped bracket 21, and the plurality of pointers 216 are all located above the scale line 217;

[0028] When the film passes between the two vertical parts of the portal bracket 21 and is above the support roller 24, by starting the servo motor 22, the driving gear 23 can be driven to rotate. With the meshing of the driving gear 23 and the driven gear 25, the adjusting threaded rod 26 can be driven to rotate, thereby driving the circular knives 272 on the outer walls of a number of turntables 271 with equal spacing to rotate simultaneously. In cooperation with the rotation of the support roller 24, the film is slit. At the same time, the turntable 271 threadedly connected to the adjusting threaded rod 26 is limited by two movable rings 273 and can maintain its position unchanged without affecting rotation. At this time, the fixing bolt 215 passes through the positioning threaded hole 214 and abuts against the top of the square slide rod 212. Therefore, by means of the connection between the gantry suspension plate 274 at the bottom of the slider 213 and the movable rings 273 on the left and right sides of the turntable 271, the stability of the turntable 271 following the rotation of the adjusting threaded rod 26 can be ensured. When it is necessary to adjust the spacing between a number of circular knives 272, only need to rotate and remove the fixing bolt 215 to release the limit on the slider 213, and then the position of the turntable 271 can be adjusted by rotating the movable ring 273 on the outer wall of the adjusting threaded rod 26. When the turntable 271 moves, the gantry suspension plate 274 can drive the slider 213 to slide on the outer wall of the square slide rod 212, and at the same time, the position of the spacing can be determined by cooperating with the pointer 216 pointing to the scale line 217. And because the zero point of the scale line 217 is in the middle and the numbers increase towards both sides, when adjusting, the middle turntable 271 does not need to move its position, and only need to rotate the two side turntables 271 towards the immovable middle turntable 271 and close them. After adjustment, then pass the fixing bolt 215 through the positioning threaded hole 214 and rotate it tightly until its bottom end abuts against the top of the square slide rod 212. By means of the resistance between the bottom end of the fixing bolt 215 and the square slide rod 212, the fixing of the slider 213 can be completed, so that the gantry suspension plate 274 at the bottom of the slider 213 and the movable rings 273 on the left and right sides of the turntable 271 are fixed in position, thereby realizing the fixing of the position of the circular knives 272 on the outer wall of the turntable 271.

[0029] As Figure 4 shown, the film positioning mechanism 3 includes two vertical plates 31, both of which are fixedly installed on the top of the box body base 1. A guide roller 32 is movably installed between the opposite surfaces of the two vertical plates 31. An adjusting box 33 is fixedly installed on the top of the two vertical plates 31. An adjusting groove 34 is opened at the bottom of the adjusting box 33. A left - right threaded rod 35 is movably installed on the right side inner wall of the adjusting groove 34. The left end of the left - right threaded rod 35 penetrates to the left side of the adjusting box 33 and is fixedly installed with a rotating handle 36. The left and right sides of the outer wall of the left - right threaded rod 35 are respectively provided with thread walls with opposite threads, and both thread walls are threadedly installed with suspension plates 37. Both suspension plates 37 are slidably connected to the adjusting groove 34. The bottom ends of both suspension plates 37 are fixedly installed with film positioning rings 38. Both film positioning rings 38 are sleeved on the outer wall of the guide roller 32 and rubber pads are fixedly installed on the opposite surfaces;

[0030] When the film roll is pulled, it will first pass through the top of the guide roller 32 between the two vertical plates 31, which plays a role in increasing the tension of the film. For films with different top widths, the rotating handle 36 at the left end of the rotating adjustment box 33 can be used to drive the positive and negative threaded rods 35 in the adjustment slots 34 to rotate, and the threaded walls of the opposite threads on the left and right sides of the outer wall of the positive and negative threaded rods 35 and the threaded connection of the hanging plate 37 can control the two film positioning rings 38 to move closer to each other on the outer wall of the guide roller 32 until the rubber pads on the opposite sides are pressed against the two sides of the film to limit the position, thereby preventing the film from deviating left and right.

[0031] like Figure 5 As shown, the tension adjustment mechanism 4 includes two electric push rods 41, both of which are fixedly mounted on the top of the box base 1, and the output ends of the two electric push rods 41 are fixedly mounted with extension plates 42, and the bottoms of the two extension plates 42 are fixedly mounted with fixed plates 43, the two fixed plates 43 are located between the two electric push rods 41, and a tension adjustment roller 44 is fixedly mounted between the opposite surfaces of the two fixed plates 43;

[0032] After the film passes through the top of the guide roller 32, it can then pass through the bottom of the tension-adjusting pressure roller 44. The tension level is increased by the pressing of the tension-adjusting pressure roller 44. When the film tension needs to be adjusted, the two electric push rods 41 can be uniformly controlled by the controller. The controller monitors the position and speed information of each push rod in real time, and compares and adjusts through the feedback system. After the two electric push rods 41 are started, the fixed plate 43 at the bottom of the extension plate 42 can be used to drive the tension-adjusting pressure roller 44 to rise, thereby reducing the tension on the film. Driving the tension-adjusting pressure roller 44 downward can increase the tension on the film.

[0033] The following is a detailed description of the working principle of the horizontal film slitting machine.

[0034] like Figures 1-5As shown in the figure, when processing the film, the film coil raw material can be movably installed between the two support plates included in the raw material winding mechanism 5, and after pulling out the film, it passes through the film positioning mechanism 3, the tension adjusting mechanism 4, and is installed on the outer wall of the winding roller between the two winding roller brackets included in the discharging and winding mechanism 6. At this time, starting the winding motor can carry out the winding and slitting work of the film. When the film passes between the two vertical parts of the gantry bracket 21, it is above the support roller 24. By starting the servo motor 22, the driving gear 23 can be driven to rotate. With the meshing of the driving gear 23 and the driven gear 25, the adjusting screw rod 26 can be driven to rotate, so as to drive the circular knives 272 on the outer walls of a number of equally spaced turntables 271 to rotate at the same time. With the rotation of the support roller 24, the film is slit. At the same time, the turntable 271 threadedly connected to the adjusting screw rod 26 is limited by the two movable rings 273 and can maintain its position unchanged without affecting rotation. At this time, the fixing bolt 215 passes through the positioning threaded hole 214 and abuts against the top of the square slide rod 212. Therefore, by means of the connection between the bottom of the slider 213 and the gantry hanging plate 274 on the left and right sides of the turntable 271 and the movable rings 273, the stability of the turntable 271 following the rotation of the adjusting screw rod 26 can be ensured. When it is necessary to adjust the spacing between a number of circular knives 272, only need to rotate and remove the fixing bolt 215 to release the limit on the slider 213, and then the position of the turntable 271 can be adjusted by rotating the movable ring 273 on the outer wall of the adjusting screw rod 26. When the turntable 271 moves, the slider 213 can be driven to slide on the outer wall of the square slide rod 212 by the gantry hanging plate 274, and at the same time, the spacing can be determined by cooperating with the pointer 216 pointing to the position of the scale line 217. And because the zero point of the scale line 217 is in the middle and the numbers increase towards both sides, when adjusting, the middle turntable 271 does not need to move its position, and only need to rotate the two side turntables 271 towards the stationary middle turntable 271 to get closer. After adjustment, then pass the fixing bolt 215 through the positioning threaded hole 214 and tighten it against the top of the square slide rod 212 to complete the fixing of the turntable 271. At the same time, when the film coil is pulled, it will first pass through the top of the guide roller 32 between the two vertical plates 31, which plays a role in improving the film tension. For films with different widths at the top, by rotating the rotating handle 36 at the left end of the adjusting box 33, the forward and reverse screw rod 35 in the adjusting groove 34 can be driven to rotate, and with the threaded connection between the threaded walls of the opposite threads on the left and right sides of the outer wall of the forward and reverse screw rod 35 and the hanging plate 37, the two film positioning rings 38 can be controlled to approach each other on the outer wall of the guide roller 32 until the rubber pads on the opposite surfaces abut against both sides of the film for limiting, so as to prevent the film from shifting left and right. At the same time, after the film passes through the top of the guide roller 32, it can then pass through the bottom of the tension adjusting roller 44, and the tension level is improved by the pressing of the tension adjusting roller 44. And when it is necessary to adjust the film tension, only need to synchronously control the start of the two electric push rods 41 by means of the existing operating system, and the tension adjusting roller 44 can be driven to rise by the fixing plate 43 at the bottom of the extension plate 42, thereby reducing the tension on the film.Pressing down the driving tension adjusting pressure roller 44 can increase the tension on the film.

[0035] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit of the present utility model are within the protection scope of the present utility model.
