Abstract
Description
Technical Field
[0001] This utility model relates to the field of yarn tube paper production technology, and in particular to a conveying device for yarn tube paper production. Background Technology
[0002] Paper tubes are mainly used in the production of cores and pipes, including industrial pipes, mulch pipes, fireworks pipes, textile pipes, spiral pipes, pagoda pipes, parallel pipes, various paper corner protectors, cartons, honeycomb cardboard, etc. The reason paper breaks during transport is that the tension it experiences is unstable, potentially increasing instantaneously to more than three times the normal tension value. This is especially true when the transport speed increases rapidly; the impact tension often causes the paper to break.
[0003] Because the diameter of the paper roll is large, it needs to be unwound by a motor. The change in paper diameter at the winding and unwinding positions causes the paper speed on both sides to change. When there is a speed difference, it can cause the paper to break or loosen. Furthermore, when the winding process is about to end, the paper may suddenly come loose at one end, which can easily cause the wound paper to fall apart. Utility Model Content
[0004] The purpose of this utility model is to address the problems existing in the background technology by proposing a conveying device for yarn tube paper production.
[0005] The technical solution of this utility model is a conveying device for producing yarn tube paper, comprising:
[0006] The device includes a tension detection device, a tension adjustment device, and two unwinding frames, with the tension detection device and the tension adjustment device installed between the two unwinding frames.
[0007] Two sets of linear speed detection devices are installed on the unwinding frames on both sides. Each linear speed detection device includes a pressure roller, a fourth rotating frame, a displacement detection mechanism, and two sets of elastic connecting components. The pressure roller is rotatably installed on the fourth rotating frame, and the fourth rotating frame is slidably installed on the unwinding frame. The fourth rotating frame and the unwinding frame are elastically connected by two sets of elastic connecting components. The displacement detection mechanism is installed on the unwinding frame to detect the displacement change of the fourth rotating frame.
[0008] Preferably, the tension detection device includes a first rotating frame, a tension detector, and a tension detection roller. The tension detector is installed on the upper end of the first rotating frame, and the rotating shaft of the tension detection roller is installed on the tension detector.
[0009] Preferably, the tension adjustment device includes a gantry frame, an electric telescopic rod, a second rotating frame, and a tension adjustment roller. The electric telescopic rod is mounted on the gantry frame, the second rotating frame is connected to the output shaft of the electric telescopic rod, and the tension adjustment roller is rotatably mounted on the second rotating frame.
[0010] Preferably, the elastic connection assembly includes a spring, a connecting slider, and a guide slide rod. Sliding holes are provided on both sides of the unwinding frame. The guide slide rod is located inside the sliding holes. The connecting slider is slidably mounted on the guide slide rod and connected to the end of the fourth rotating frame. The spring is sleeved and installed on the lower part of the guide slide rod.
[0011] Preferably, the displacement detection mechanism is a magnetic scale body, which is vertically mounted on the unwinding frame. A magnetic head is slidably mounted on the magnetic scale body, and the magnetic head is connected to the connecting slider on the corresponding side.
[0012] Preferably, the conveying equipment for producing yarn tube paper also includes a third rotating frame, on which a rotating roller is rotatably mounted, and both ends of the rotating roller are equipped with limit rings.
[0013] Compared with the prior art, the present invention has the following beneficial technical effects:
[0014] 1. This technical solution uses an elastic connecting component to ensure that the pressure roller is always pressed against the surface of the paper roll. When the diameter of the paper roll changes, the pressure roller moves, and the displacement detection mechanism can detect the displacement change of the pressure roller and feed the data back to the computer. The diameter of the paper roll can then be calculated. By acquiring the rotational speed information of the servo motor, the linear velocity of the outer side of the paper roll can be calculated. The computer controls the linear velocity of the paper roll at the unwinding point to be the same as that at the winding point, thereby preventing the paper from breaking or loosening during the winding process.
[0015] 2. Furthermore, by setting up an elastic connecting component, the pressure roller is always pressed against the paper roll, thereby preventing the paper roll from loosening and ensuring the tightness of the paper winding. Attached Figure Description

[0019] Example 1
[0020] like Figures 1-3 As shown in the figure, the conveying equipment for yarn tube paper production proposed in this embodiment includes a tension detection device, a tension adjustment device, two unwinding frames 2, and two sets of linear speed detection devices.
[0021] A tension detection device and a tension adjustment device are installed between two unwinding frames 2. The tension detection device includes a first rotating frame 4, a tension detector 5, and a tension detection roller 6. The tension detector 5 is installed on the upper end of the first rotating frame 4, and the rotating shaft of the tension detection roller 6 is installed on the tension detector 5. Through the cooperation of the tension detection roller 6 and the tension detector 5, the tension of the paper during movement can be detected. The tension adjustment device includes a gantry frame 7, an electric telescopic rod 9, a second rotating frame 10, and a tension adjustment roller 11. The electric telescopic rod 9 is installed on the gantry frame 7, the second rotating frame 10 is connected to the output shaft of the electric telescopic rod 9, and the tension adjustment roller 11 is rotatably installed on the second rotating frame 10. The tension detector 5 feeds back the detected data to the controller, which controls the electric telescopic rod 9 to drive the tension adjustment roller 11 to rise and fall, thereby changing the tension of the paper so that the tension of the paper is always maintained within the set range.
[0022] Two sets of linear speed detection devices are respectively installed on the unwinding frames 2 on both sides. The linear speed detection device includes a pressure roller 8, a fourth rotating frame 16, a displacement detection mechanism, and two sets of elastic connection assemblies. The elastic connection assemblies include a spring 17, a connecting slider 18, and a guide slide rod 19. Sliding holes 201 are opened on both sides of the unwinding frame 2. The guide slide rod 19 is located inside the sliding hole 201. The connecting slider 18 is slidably mounted on the guide slide rod 19 and connected to the end of the fourth rotating frame 16. The spring 17 is sleeved and installed on the lower part of the guide slide rod 19. The setting allows the pressure roller 8 to always be in contact with the surface of the paper roll. The pressure roller 8 is rotatably mounted on the fourth rotating frame 16, which is slidably mounted on the unwinding frame 2. The fourth rotating frame 16 and the unwinding frame 2 are elastically connected by two sets of elastic connecting components. The displacement detection mechanism is mounted on the unwinding frame 2 to detect the displacement change of the fourth rotating frame 16. The displacement detection mechanism is a magnetic scale body 14, which is vertically mounted on the unwinding frame 2. A magnetic head is slidably mounted on the magnetic scale body 14, and the magnetic head is connected to the connecting slider 18 on the corresponding side.
[0023] In this embodiment, the take-up roller and the paper roll are placed on the unwinding racks 2 on both sides. Two servo motors are installed on the unwinding racks 2 on both sides to perform take-up and unwinding operations on the take-up roller and the paper roll, respectively. Since the paper diameter changes at the take-up and unwinding positions, the paper movement speed on both sides will be different even when the two motors are driven at the same speed. Based on this, this technical solution uses an elastic connecting component to ensure that the pressure roller 8 is always pressed against the surface of the paper roll. When the diameter of the paper roll changes, the pressure roller 8 moves along the... The moving magnetic head moves on the magnetic scale body 14, and the magnetic scale body 14 feeds back the detected signal to the computer. The computer obtains the diameter data of the paper roll and the rotation speed information of the servo motor. From this, the linear velocity of the outer side of the paper roll can be calculated. By controlling the linear velocity of the paper roll at the unwinding point to be the same as that at the winding point, the paper roll is prevented from breaking or loosening during the winding process. Furthermore, by setting the elastic connecting component, the pressure roller 8 is always pressed against the paper roll, thereby preventing the paper roll from unwinding and ensuring the tightness of the paper winding.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
