Description

Technical Field

[0001] The utility model belongs to the technical field of winding machines, in particular to a winding machine with the function of winding tail materials. Background Art

[0002] A winder is a common device used to wind a strip into a roll. Its structure includes a rotating shaft and a motor for driving the rotating shaft to rotate. The motor drives the rotating shaft to rotate, thereby winding the strip around the rotating shaft.

[0003] However, when the existing winder is winding the tail material, since the end of the tail material is not fixed, when the winding speed is too fast, the tail material can easily flip from one end of the paper roll to the other end of the paper roll, and drive the belt material connected to the tail material to unwind together. At the same time, after the winding is completed, the tail material part is not fixed to the paper roll, and the tail material is not taut, which can easily lead to the paper roll being loosely wound.

[0016] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0017] like Figures 1 to 3 As shown, it is a schematic diagram of the structure of the winder with the tail material winding function provided by the utility model. The winder with the tail material winding function includes a winding body 10, a material guide assembly 20 arranged on one side of the winding body 10, and a pressing assembly 30 arranged on the top of the winding body 10. The winder with the tail material winding function also includes some other functional modules, such as a power distributor of a controller arranged on one side of the winding body 10, etc., which should be well known to those skilled in the art and will not be described in detail one by one here.

[0018] The winding body 10 includes a frame 11, two support arms 12 hingedly arranged on the frame 11, a first driving cylinder 13 hingedly arranged on the frame 11 and one end of each support arm 12, and a supporting portion 14 arranged at the other end of the two support arms 12.

[0019] The frame 11 is used to provide a mounting position for each component. The frame 11 includes two spaced and vertically arranged mounting plates. Figure 1 It is a vertical cross-sectional view, so only one mounting plate can be seen. A mounting rod 111 is horizontally inserted between the two mounting plates of the frame body 11. The mounting rod 111 is arranged at one end of the frame body 11 near the top.

[0020] The support arm 12 is rotatably mounted on the mounting rod 111. One end of the support arm 12 on which the supporting portion 14 is disposed extends out of the frame 11 and faces the material guide assembly 20. In this embodiment, the height of the end of the support arm 12 on which the supporting portion 14 is disposed is always lower than the height of the mounting rod 111, so that when a paper roll is placed on the supporting portion 14, the center of gravity of the entire device is lower.

[0021] The driving end of the first driving cylinder 13 is hinged to the support arm 12, and the middle part of the first driving cylinder 13 is hinged to the frame body 11. When the first driving cylinder 13 is controlled to extend and retract, it will drive one end of the support arm 12 to move, thereby causing the other end of the support arm 12 to move up and down around the mounting rod 111.

[0022] A groove 141 is provided at the top of the supporting portion 14. The groove bottom of the groove 141 is arc-shaped in cross section, so that the paper roll is not easy to fall out of the groove 141 when placed in the groove 141. The axis of the groove 141 is perpendicular to the extension direction of the support arm 12, and the height of the side wall of the groove 141 away from the mounting rod 111 is higher than the height of the side wall on the other side, so as to ensure that the paper roll will not fall out from the side wall away from the mounting rod 111 during the lifting process of the support arm 12.

[0023] It should be noted that the supporting portion 14 is used to support the shaft of the paper roll, and a shaft sleeve is sleeved on the outside of the shaft, and the shaft sleeve is located between the two supporting portions 14. The shaft is driven by a motor to rotate around the axis. This structure of rotating around the axis is well known to those skilled in the art, and is not the main content of the utility model, and will not be described here. When the supporting portion 14 moves with the rotation of the support portion 12, the shaft located in the supporting portion 14 will also move accordingly, so that the height of the shaft can be adjusted according to the thickness of the paper roll after rolling to prevent the paper roll from touching the ground.

[0024] The material guiding assembly 20 includes a mounting seat 21 , a material pressing assembly 22 disposed on the top of the mounting seat 21 , a guide shaft 23 disposed at the rear of the material pressing assembly 22 , and a material discharging guiding assembly 24 disposed at the rear of the guide shaft 23 .

[0025] The mounting seat 21 is used to provide a mounting position for each component. The pressing assembly 22 includes two pressing shafts 221 arranged at intervals, and the strip passes through the gap between the two pressing shafts 221 and is flattened. The guide shaft 23 is used to change the direction of the sheet. The bottom end of the guide shaft 23 is flush with the gap between the two pressing shafts 221. The bottom end of the guide shaft 23 is higher than the height of the position where the guide plate 241 described below is hinged to the mounting seat 21.

[0026] The material discharging guide assembly 24 includes a material guide plate 241 hinged on the side of the mounting seat 21 facing the winding body 10, and a second driving cylinder 242 hinged between the material guide plate 241 and the mounting seat 21. The material guide plate 241 is used to support the tail of the tape to prevent the tail from falling to the ground. When in use, the material guide plate 241 will be controlled to rise when the last tail is rolled, so that the tail of the material guide plate 241 is higher than the base, and the tail will be rolled along the material guide plate 241.

[0027] The roll pressing assembly 30 includes two support seats 31 spaced apart at the top of the frame 11 , a rotating shaft 32 horizontally arranged between the support seats 31 , a material guarding portion 33 rotatably mounted on the rotating shaft 32 , and a material pressing portion 34 arranged on the material guarding portion 33 .

[0028] The support seat 31 is fixed on the frame 11 to install the rotating shaft 32 , and the rotating shaft 32 is used to provide an installation position for the material protection portion 33 .

[0029] The material guarding portion 33 includes a rotating arm 331 sleeved on the rotating shaft 32 , a third driving cylinder 332 disposed between the rotating arm 331 and the frame body 11 , and a first wheel body 333 disposed at the end of the rotating arm 331 .

[0030] The rotating arm 331 is connected to the support seat 31 through the rotating shaft 32, and can rotate with the rotating shaft 32 as the rotation center. One end of the rotating arm 331 is connected to the third driving cylinder 332, and the other end is a free end extending toward the supporting portion 14. The length of the rotating arm 331 from the connection point with the rotating shaft 32 to the connection point with the third driving cylinder 332 is shorter than the length from the connection point with the rotating shaft 32 to the first wheel body 333, so that the third driving cylinder 332 can drive the rotating arm 331 to rotate a larger distance along the rotating shaft 32 by driving a smaller distance.

[0031] A section of the rotating arm 331 close to the first wheel 333 is in an arc shape, and the material pressing arm 341 described below is hinged at the arc of the rotating arm 331, so that the first wheel 333 on the rotating arm 331 can be exactly located at the top of the paper roll, which is biased towards the side where the strip is rolled up, and thus the tail material can be timely blocked from rolling up. The driving end of the third driving cylinder 332 is hinged to one end of the rotating arm 331, and the other end of the third driving cylinder 332 is hinged to the frame 11. The third driving cylinder 332 is controlled to extend and retract, thereby driving one end of the rotating arm 331 to move, and then the other end of the rotating arm 331 rotates around the rotating shaft 32.

[0032] The first wheel body 333 is used to limit the position of the material belt. When in use, the rotating arm 331 slowly rotates and rises as the diameter of the paper roll increases, so that the first wheel body 333 is always set at a distance from the paper roll. At the same time, during the winding process of the tail material, it can also prevent the tail material from moving to the other side of the paper roll as the paper roll rotates, causing the paper roll to loosen.

[0033] The pressing portion 34 includes a pressing arm 341 hinged on the rotating arm 331 , a second wheel body 342 rotatably disposed at the end of the pressing arm 341 , and a fourth driving cylinder 343 hinged between the pressing arm 341 and the rotating arm 331 .

[0034] The driving end of the fourth driving cylinder 343 is hinged to the middle part of the pressing arm 341, and the fourth driving cylinder 343 is hinged to the rotating arm 331, so that when the fourth driving cylinder 343 is controlled to extend and retract, the rotating arm 331 will be controlled to rotate and make the second wheel body 342 press on the surface of the paper roll, so as to press the tail material and prevent the paper roll from loosening.

[0035] It should be noted that the control of each driving cylinder is realized by a single chip microcomputer or a PC. The principle is: by measuring and calculating the winding speed and the thickness of the strip, the thickness of the paper roll at different times is simulated, so as to control the extension of different driving cylinders to the corresponding length to achieve the effect of protecting and pressing the material. At the same time, the judgment of the tail material is realized by receiving the cutting signal of the tail material cutting device. This control method is well known to those skilled in the art and is not the main content of the utility model, so it will not be repeated here.

[0036] Compared with the prior art, the winding machine with the tail material winding function provided by the utility model can not only prevent the tail material from rolling up, but also fix the tail material by setting the pressing coil assembly 30. Specifically, the pressing coil assembly 30 includes a material guarding portion 33 and a material pressing portion 34 arranged on the material guarding portion 33. The material guarding portion 33 includes a rotating arm 331, a third driving cylinder 332 arranged at one end of the rotating arm 331, and a first wheel body 333 arranged at the end of the rotating arm 331. The third driving cylinder 332 drives the rotating arm 331 to rotate. 31, so that the first wheel body 333 is spaced apart from the paper roll, and then when the tail material turns over, the first wheel body 333 will block the tail material from driving the rest of the strip to turn over, the pressing part 34 includes a pressing arm 341 hinged on the rotating arm 331, a fourth driving cylinder 343 arranged at one end of the pressing arm 341, and a second wheel body 342 arranged at the end of the pressing arm 341. In the process of winding the tail material, the fourth driving cylinder 343 is controlled to extend, so that the pressing arm 341 drives the second wheel body 342 to press the tail material onto the paper roll, thereby positioning the paper roll.
