[0002] The transparent paper frame of the small box transparent paper packaging machine is responsible for unrolling and conveying the transparent paper of the transparent paper roll. The original paper frame adopts a three-roller structure, one roller is fixedly installed on the left side, and the other two rollers are installed on the right side swing arm. The transparent paper is unrolled by alternately passing through the three rollers. The bottom of the right side swing arm is installed on the swing arm seat. In order to ensure the stretching and straightening of the transparent paper, a tension spring is arranged at the bottom of the right side swing arm. During the conveying process of the transparent paper, the upper part of the swing arm is pulled to the left by the transparent paper, and the tension spring also has a right pulling force on the bottom of the swing arm. Under the joint action of the transparent paper pulling force and the tension spring pulling force, the transparent paper always maintains a moderately tight state.

[0003] When the transparent paper roll is almost used up, the radius of the transparent paper roll is small at this time, and a larger pulling force is needed to pull the transparent paper out of the transparent paper roll. However, the left roller on the existing transparent paper frame is fixed and cannot be automatically adjusted with the consumption of the transparent paper, which leads to an excessive swing range of the right swing arm, and even causes the transparent paper to be not conveyed in place, resulting in the following problems: the transparent paper cannot wrap the cigarette package, causing quality risks; the transparent paper conveying is blocked, reducing the equipment operation efficiency.

[0017] The utility model discloses the beneficial effects of:

[0018] The novel transparent paper roll unrolling frame provided by the utility model changes the left side fixed roller into a flexible swing roller. The left swing arm seat is subjected to the left tension spring tension, and in the non-working state, the left limiting rod is close to the left limiting column. In the ideal working state, the left roller is subjected to the constant tension of the transparent paper, so that the left roller frame is subjected to the torque center with the left hinge shaft as the axis, and the torque in the clockwise direction, so that the left roller frame rotates clockwise around the left hinge shaft, and at the same time, the left swing arm seat is subjected to the increased tension of the left tension spring, until the force balance of the left swing arm seat.

With the decrease of the radius of the transparent paper roll, the swing angle of the left roller frame increases, and when the transparent paper roll is almost used up, the swing angle of the left roller frame reaches the maximum since the radius of the transparent paper roll is the smallest at this time. Similarly, the right swing arm seat is subjected to the right tension spring tension, and in the non-working state, the right limiting rod is close to the right limiting column. In the ideal working state, the right side first roller and the right side second roller are subjected to the constant tension of the transparent paper, so that the right roller frame is subjected to the torque center with the right hinge shaft as the axis, and the torque in the counterclockwise direction, so that the right roller frame rotates counterclockwise around the right hinge shaft, and at the same time, the right swing arm seat is subjected to the increased tension of the right tension spring, until the force balance of the right swing arm seat. In the actual work, since the small box transparent paper packaging machine does not run at a constant speed, the radius of the transparent paper roll gradually decreases, so that the transparent paper tension of the right roller frame is changed, and the tension of the right tension spring of the right swing arm seat is also changed, so that the right roller frame swings around the right hinge shaft. With the decrease of the radius of the transparent paper roll, the swing angle of the right roller frame increases, and when the transparent paper roll is almost used up, the swing angle of the right roller frame reaches the maximum since the radius of the transparent paper roll is the smallest at this time. During the operation of the novel transparent paper roll unrolling frame, since the left roller frame and the right roller frame can swing flexibly, the left roller frame and the right roller frame can be automatically adjusted with the consumption of the transparent paper, the swing amplitude of the right roller frame can be avoided to be too large, the transparent paper can be ensured to be transported to the position, and the problems of the transparent paper being unable to wrap the cigarette packet, the quality hidden danger, the transparent paper transportation being blocked and the equipment operation efficiency being reduced can be solved.

[0030] As Figure 1 and Figure 2The utility model provides a novel transparent paper roll unrolling frame, including frame 100, left swing arm subassembly 200 and right swing arm subassembly 300. Among them, frame 100 rotatory installation has transparent paper roll 10, left swing arm subassembly 200 includes left hinged axle 210, left swing arm seat 220, left gyro wheel frame 230, left limiting rod 240, left tension spring 250 and left limiting column 260, left hinged axle 210 sets up at the left side of frame 100, and left swing arm seat 220 is connected with left hinged axle 210 rotationally, and one end of left gyro wheel frame 230 is fixedly connected with left swing arm seat 220, and the other end of left gyro wheel frame 230 is provided with left side gyro wheel 231, and one end of left limiting rod 240 is fixedly connected with left swing arm seat 220, and one end of left tension spring 250 is connected with left limiting rod 240, and the other end of left tension spring 250 is connected with frame 100, and left limiting column 260 sets up on frame 100, and left limiting rod 240 can abut with left limiting column 260 under the pull of left tension spring 250, right swing arm subassembly 300 includes right hinged axle 310, right swing arm seat 320, right gyro wheel frame 330, right limiting rod 340, right tension spring 350 and right limiting column 360, and right hinged axle 310 sets up at the right side of frame 100, and right swing arm seat 320 is connected with right hinged axle 310 rotationally, and one end of right gyro wheel frame 330 is fixedly connected with right swing arm seat 320, and right gyro wheel frame 330 is provided with right side first gyro wheel 331 and right side second gyro wheel 332, and right side first gyro wheel 331 is located in the one end of right gyro wheel frame 330 far from right swing arm seat 320, and right side second gyro wheel 332 is located between right side first gyro wheel 331 and right swing arm seat 320, and one end of right limiting rod 340 is fixedly connected with right swing arm seat 320, and one end of right tension spring 350 is connected with right limiting rod 340, and the other end of right tension spring 350 is connected with frame 100, and right limiting column 360 sets up on frame 100, and right limiting rod 340 can abut with right limiting column 360 under the pull of right tension spring 350, and the transparent paper 20 of transparent paper roll 10 in turn passes right side second gyro wheel 332, left side gyro wheel 231 and right side first gyro wheel 331.

[0031] The novel transparent paper roll unrolling frame provided by the utility model changes the original left side fixed roller into a roller capable of swinging flexibly. The left swing arm base 220 is subjected to the tension of the left tension spring 250, and in the non-working state, the left limiting rod 240 abuts against the left limiting column 260. In the ideal working state, the left roller 231 is subjected to the constant tension of the transparent paper 20, so that the left roller frame 230 is subjected to the torque centering on the left hinge shaft 210 as the torque center and the torque in the clockwise direction, so that the left roller frame 230 rotates clockwise around the left hinge shaft 210, and meanwhile, the left swing arm base 220 is subjected to the increased tension of the left tension spring 250 until the force balance of the left swing arm base 220 is reached. In the actual working process, since the small-box transparent paper packaging machine does not run at a constant speed and the radius of the transparent paper roll 10 gradually decreases, the tension of the transparent paper 20 on the left roller frame 230 is variable, so that the tension of the left tension spring 250 on the left swing arm base 220 is also variable, so that the left roller frame 230 swings around the left hinge shaft 210 as the axis. With the decrease of the radius of the transparent paper roll 10, the swing angle of the left roller frame 230 increases, and when the transparent paper roll 10 is almost used up, the swing angle of the left roller frame 230 reaches the maximum since the radius of the transparent paper roll 10 is the smallest at this time.

[0032] Similarly, the right swing arm base 320 is subjected to the tension of the right tension spring 350, and in the non-working state, the right limiting rod 340 abuts against the right limiting column 360. In the ideal working state, the right side first roller 331 and the right side second roller 332 are subjected to the constant tension of the transparent paper 20, so that the right roller frame 330 is subjected to the torque centering on the right hinge shaft 310 as the torque center and the torque in the counterclockwise direction, so that the right roller frame 330 rotates counterclockwise around the right hinge shaft 310, and meanwhile, the right swing arm base 320 is subjected to the increased tension of the right tension spring 350 until the force balance of the right swing arm base 320 is reached. In the actual working process, since the small-box transparent paper 20 packaging machine does not run at a constant speed and the radius of the transparent paper roll 10 gradually decreases, the tension of the transparent paper 20 on the right roller frame 330 is variable, so that the tension of the right tension spring 350 on the right swing arm base 320 is also variable, so that the right roller frame 330 swings around the right hinge shaft 310 as the axis. With the decrease of the radius of the transparent paper roll 10, the swing angle of the right roller frame 330 increases, and when the transparent paper roll 10 is almost used up, the swing angle of the right roller frame 330 reaches the maximum since the radius of the transparent paper roll 10 is the smallest at this time.

[0033] In some embodiments, the first screw 110 is threadedly connected to the rack 100, and the end of the left tension spring 250 away from the left limiting rod 240 is connected to the first screw 110, so as to realize the detachable connection of the left tension spring 250 and the rack 100. The second screw 120 is threadedly connected to the rack 100, and the end of the right tension spring 350 away from the right limiting rod 340 is connected to the second screw 120, so as to realize the detachable connection of the right tension spring 350 and the rack 100.

[0034] In some embodiments, the distance between the right second roller 332 and the right first roller 331 is less than the distance between the right second roller 332 and the right swing arm base 320, and according to the principle of leverage, the above structure can reduce the pulling force required to pull the transparent paper 20. The left swing arm base 220 is embedded with a first bearing, and the left swing arm base 220 is rotatably connected to the left hinge shaft 210 through the first bearing, to ensure the smoothness of the rotation of the left swing arm base 220 relative to the left hinge shaft 210. The right swing arm base 320 is embedded with a second bearing, and the right swing arm base 320 is rotatably connected to the right hinge shaft 310 through the second bearing, to ensure the smoothness of the rotation of the right swing arm base 320 relative to the right hinge shaft 310.

[0035] In some embodiments, a paper tray is arranged on the rack 100, and the transparent paper roll 10 is mounted on the paper tray, and the transparent paper roll 10 is supported by the paper tray.

[0036] During the operation of the novel transparent paper roll unwinding frame, the left roller frame 230 and the right roller frame 330 can swing flexibly, and the left roller frame 230 and the right roller frame 330 can automatically adjust with the consumption of the transparent paper 20. The swing of the left roller frame 230 can share the swing amplitude of the right roller frame 330, so that the swing amplitude of the right roller frame 330 is not too large, thereby ensuring that the transparent paper 20 is conveyed to the position, and further solving the problems of the transparent paper 20 failing to wrap the cigarette packet, causing quality hidden dangers, the transparent paper 20 conveying being blocked, and reducing the equipment operation efficiency.
