Description

Technical Field

[0001] The present invention relates to the technical field of paper rolling equipment, and in particular to an automatic rolling device for rolling up a paper web. Background Art

[0002] In the paper roll processing technology, the excess paper after slitting and winding is manually removed, which is time-consuming and labor-intensive, and cannot be reused. The paper web cut by the slitting machine needs to be rolled up on a paper roll. The excess paper head paper web also needs to be rolled up on the paper roll. The existing paper web winding device includes a motor, a drive shaft, and a paper roll mounted on the drive shaft. The motor drives the drive shaft to rotate, and the paper roll rotates accordingly, and the paper web from the slitting machine is rolled up on the paper roll to form a paper roll.

[0003] During the paper web reeling process, as the paper web is continuously wound around the paper roll, the diameter of the paper roll becomes larger and larger, while the rotation speed of the drive shaft and the paper roll remains unchanged. This causes the linear speed of the outer ring of the paper roll and the movement speed of the paper web to increase continuously, and the pulling force on the paper web also increases continuously, which often causes the paper web to be torn.

[0004] Moreover, in order to reduce the occurrence of paper web breakage, the operator needs to always pay attention to the changes in the diameter of the paper roll on the paper drum so as to shut down the reeling operation in time, which increases the operator's workload. Utility Model Content

[0005] The technical problem to be solved by the present disclosure is to provide an automatic winding device for winding a paper web, which can prevent the paper web from being broken due to excessive tension when being wound.

[0006] To solve the above technical problems, according to one aspect of the present disclosure, an automatic winding device for winding a paper web is provided, comprising: a support frame; a driving unit, mounted on the support frame, having a horizontally extending driving shaft, and also comprising: a pair of rotatable guide rollers, mounted on the support frame, and located upstream of the driving shaft along the traveling direction of the paper web, a guide channel being formed between the pair of rotatable guide rollers to guide the paper web to pass through the guide channel; a tension sensor, comprising a fixedly mounted sensor body and a sensing rod assembly connected to the sensor body, the sensing rod assembly being located between the guide roller and the driving shaft along the traveling direction of the paper web, and contacting the paper web to sense the tension exerted on the paper web; a damping device, arranged around the driving shaft, applying a damping force to the driving shaft to control the rotational speed of the driving shaft; and a control unit, connected to the tension sensor and the damping device, receiving a tension sensing signal from the tension sensor, and outputting a damping control signal to the damping device.

[0007] In the present disclosure, the reaction force from the paper web sensed by the tension sensor can reflect the magnitude of the tension exerted by the drive shaft on the paper web, thereby realizing the sensing of the tension. The damping device receives the damping control signal from the control unit, adjusts the damping force applied to the drive shaft, thereby controlling the rotation speed of the drive shaft, thereby realizing the control of the paper web tension, preventing the paper web from being broken due to excessive tension, and allowing the drive shaft to rotate at a higher speed to increase the paper web winding speed when the tension is small. At the same time, the drive shaft extends horizontally, making it easier to load and unload the paper roll.

[0008] Furthermore, the automatic winding device also includes: an air pump valve, and an air shaft, which is connected to the air pump valve to achieve inflation and deflation. The air shaft is sleeved outside the drive shaft and is configured so that a paper roll for winding the paper web can be sleeved outside the air shaft, and the paper roll can be fixed or released by inflation and deflation.

[0009] In the present disclosure, by providing an inflatable shaft, the paper tube can be quickly loaded and unloaded, thereby improving work efficiency.

[0010] Furthermore, the air pump valve is connected to the control unit to achieve automatic inflation and deflation of the inflatable shaft through the control of the control unit.

[0011] In the present disclosure, the air pump valve is controlled by a control unit, so that when loading and unloading a paper roll for carrying a paper web wound on a paper roll, there is no need to manually operate the air pump valve alone, thereby improving the operating efficiency.

[0012] Furthermore, the automatic winding device also includes: a start-stop switch, which is arranged on the control unit housing of the control unit; the control unit is connected to the start-stop switch, receives a switch signal from the start-stop switch, and outputs a drive control signal to the drive unit to control the rotation and stop of the drive shaft.

[0013] In the present disclosure, by setting a start-stop switch and outputting a drive control signal to the drive unit through the control unit, the start and stop of the operation can be conveniently controlled.

[0014] Furthermore, the automatic winding device also includes: a start-stop switch, which is arranged on the control unit housing of the control unit; the control unit is connected to the start-stop switch, receives a switch signal from the start-stop switch, and outputs a drive control signal to the drive unit to control the rotation and stop of the drive shaft, and outputs an inflation and deflation control signal to the air pump valve to control the inflation and deflation of the inflatable shaft.

[0015] In the present disclosure, by setting a start-stop switch and outputting a drive control signal to the drive unit through the control unit, the start and stop of the operation can be conveniently controlled.

[0016] Furthermore, the sensing rod assembly of the tension sensor is arranged in parallel with the driving shaft and deviates from a plane defined by the axis of the driving shaft (22) and the paper web output position on the guide roller (30).

[0017] In the present disclosure, the sensing rod assembly of the tension sensor is arranged in parallel with the horizontally extending drive shaft, so that the sensing rod assembly is also arranged horizontally and deviates from the plane defined by the axis of the drive shaft (22) and the paper web output position on the guide roller (30). Such an arrangement is more conducive to the sensing rod assembly sensing the pressure change from the paper web, thereby better sensing the tension of the paper web.

[0018] Furthermore, the sensing rod assembly of the tension sensor includes a sensing inner rod and a rotating sleeve sleeved outside the sensing inner rod.

[0019] In the present disclosure, a rotating sleeve is disposed outside the sensing inner rod, so that the sensing rod assembly forms a tension guiding roller, so that the paper web can be rolled more smoothly while sensing the tension.

[0020] Furthermore, the driving unit includes: a driving unit housing; a motor disposed in the driving unit housing; and a reduction mechanism connected to the motor, wherein the driving shaft is connected to the reduction mechanism.

[0021] In the present disclosure, a speed reduction mechanism is provided in the driving unit to facilitate achieving the optimal output speed of the driving shaft.

[0022] Further, the driving shaft is arranged at a position lower than the guide roller.

[0023] In the present disclosure, the drive shaft is arranged at a lower position, so that when a paper roll is formed by winding a paper web from a slitting machine on a paper drum sleeved on the drive shaft, the height of the paper roll is adapted to the height of the operator, thereby making it easier for the operator to operate.

[0024] Furthermore, the damping device is a magnetic powder damper.

[0040] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present disclosure and its application or use. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0041] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present disclosure. As used herein, unless the context clearly indicates otherwise, the singular form is intended to include the plural form as well.

[0042] Figure 1 is a schematic diagram of the three-dimensional structure of an automatic winding device for winding a paper web according to an embodiment of the present disclosure; Figure 2 is along Figure 1The schematic cross-sectional structure diagram of the axis of the driving shaft shown in the figure shows the relative position relationship between the driving shaft, the inflatable shaft, the paper tube and the damping device; Figure 3 The invention is a block diagram of the control principle of an automatic winding device for winding a paper web according to an embodiment of the present invention.

[0043] See also Figures 1 to 3 According to one embodiment of the present disclosure, an automatic winding device for winding a paper web W includes: a support frame 10, a driving unit 20, a driving unit 20, a pair of rotatable guide rollers 30, a tension sensor 40, a damping device 50 and a control unit 60.

[0044] The driving unit 20 is mounted on the supporting frame 10. The driving unit 20 may have a driving unit housing. Figure 1 It can be seen that the drive shaft 22 extends from the drive unit 20 in a horizontal direction.

[0045] The rotatable guide roller 30 is mounted on the support frame 10 and is located upstream of the drive shaft 22 in the direction of the paper web. A guide channel is formed between the two guide rollers 30, and the paper web W is guided to pass through the guide channel. When the paper web passes through, the pair of guide rollers 30 can apply pressure to the paper web and rotate with the movement of the paper web. In this process, the paper web can not only be guided in the direction of travel, but also flattened by the pressure on the paper web.

[0046] The tension sensor 40 includes a fixedly mounted sensor body (not shown) and a sensing rod assembly 42 connected to the sensor body. The sensor body (not shown) can be mounted on the support frame 10 or on the support frame 10. Figure 1 The driving unit 20 shown in FIG. 4 is inside the driving unit housing. The sensing rod assembly 42 is located between the guide roller 30 and the driving shaft 22 along the traveling direction of the paper web, and contacts the paper web W to apply pressure to the paper web, and is subjected to a reaction force from the paper web. The sensing rod assembly 42 transmits the reaction force from the paper web to the sensor body. Since the reaction force from the paper web is related to the tension force on the paper web, the tension sensor 40 can sense the tension on the paper web W.

[0047] The damping device 50 is disposed around the driving shaft 22 and can apply a damping force to the driving shaft 22. By applying different magnitudes of the damping force, the rotation speed of the driving shaft 22 can be controlled, thereby controlling the tension of the paper web.

[0048] The control unit 60 is connected to the tension sensor 40 and the damping device 50 , receives the tension sensing signal from the tension sensor 40 , and outputs a damping control signal to the damping device 50 , so that the damping device 50 can apply a desired damping force to the drive shaft 22 .

[0049] It can be seen that in the scheme of this embodiment of the present disclosure, the reaction force from the paper web sensed by the tension sensor 40 can reflect the magnitude of the tension exerted on the paper web by the drive shaft 22, thereby realizing the sensing of the tension. The damping device receives the damping control signal from the control unit 60, adjusts the damping force applied to the drive shaft 22, thereby controlling the rotation speed of the drive shaft 22, thereby realizing the control of the tension of the paper web, preventing the paper web from being broken due to excessive tension, and at the same time, when the tension is small, allowing the drive shaft to rotate at a higher speed to increase the paper web winding speed. Moreover, since the drive shaft 22 extends horizontally, it is more convenient for the operator to load and unload the paper roll.

[0050] According to one embodiment of the present disclosure, the automatic winding device further includes an air pump valve 71 (see Figure 3 ) and an inflatable shaft 72. The air pump valve 71 can be connected to the air pump, or it can be a component of the air pump. The inflatable shaft 72 is connected to the air pump valve 71 to achieve inflation through the air pump, and can also achieve deflation. The inflatable shaft 72 is sleeved outside the drive shaft 22, and is configured so that a paper roll 74 for winding the paper web W can be sleeved outside the inflatable shaft 72, and after the paper roll 74 is installed, the paper roll 74 is fixed on the inflatable shaft 72 by inflation, or the paper roll 74 can be released by deflation. In the present disclosure, by providing the inflatable shaft 72, the paper roll 74 can be quickly loaded and unloaded, thereby improving work efficiency.

[0051] Also, see Figure 3 It can be seen that the air pump valve 71 is connected to the control unit 60, so that the air shaft 72 can be automatically inflated and deflated by the control of the control unit 60. In the present disclosure, the air pump valve is controlled by the control unit, so that when loading and unloading the paper roll 74 for carrying the paper web wound by the paper roll, there is no need to manually operate the air pump valve alone, thereby improving the working efficiency.

[0052] Come and join again Figure 1 It can be seen that according to one embodiment of the present disclosure, the automatic winding device may further include a start-stop switch 76, which may be provided on the control unit housing of the control unit 60. The control unit 60 is connected to the start-stop switch 76, receives a switch signal from the start-stop switch 76, and outputs a drive control signal to the drive unit 20, thereby controlling the rotation and stop of the drive shaft 22. In the present disclosure, by providing the start-stop switch 76 and outputting a drive control signal to the drive unit 20 through the control unit 60, the start and stop of the operation can be conveniently controlled.

[0053] According to another embodiment of the present disclosure, the control unit 60 may be further configured to be connected to the start-stop switch 76, receive a switch signal from the start-stop switch 76, and output a drive control signal to the drive unit 20 to control the rotation and stop of the drive shaft 22, and further output a charge and discharge control signal to the air pump valve 71 to control the charge and discharge of the inflatable shaft 72. In this embodiment of the present disclosure, by setting the start-stop switch 76 and outputting a drive control signal to the drive unit 20 through the control unit 60, the start and stop of the operation can be conveniently controlled.

[0054] from Figure 1 It can be seen that the sensing rod assembly 42 of the tension sensor 40 is arranged parallel to the drive shaft 22, and is arranged between the guide roller 30 and the drive shaft 22 along the traveling direction of the paper web W, and deviates from the plane defined by the axis of the drive shaft 22 and the paper web output position on the guide roller 30.

[0055] In the present disclosure, the sensing rod assembly 42 of the tension sensor 40 is arranged parallel to the horizontally extended driving shaft 22, so that the sensing rod assembly 42 is also arranged horizontally and deviates from the plane defined by the axis of the driving shaft 22 and the paper web output position on the guide roller 30. Such an arrangement is more conducive to the sensing rod assembly 42 sensing the pressure change from the paper web, thereby better sensing the tension of the paper web.

[0056] According to an embodiment not shown, the sensing rod assembly 42 of the tension sensor 40 may include a sensing inner rod and a rotating sleeve sleeved outside the sensing inner rod. By arranging the rotating sleeve outside the sensing inner rod, the sensing rod assembly forms a tension guide roller, so that while sensing the tension, the paper web is rolled more smoothly.

[0057] According to an embodiment not shown, the drive unit 20 may include a motor disposed in a housing of the drive unit and a speed reduction mechanism connected to the motor, and the drive unit further includes a drive shaft 22 connected to the speed reduction mechanism. In the present disclosure, a speed reduction mechanism is disposed in the drive unit 20 to facilitate the drive shaft 22 to output an optimal speed, which is more conducive to controlling the tension of the paper web. The speed reduction mechanism in the housing of the drive unit may be a gear transmission mechanism, a belt transmission mechanism, or a chain transmission mechanism.

[0058] from Figure 1 It can also be seen that the drive shaft 22 can be preferably arranged at a position lower than the guide roller 30. Since the drive shaft 22 is arranged at a lower position, when a paper roll is formed by winding a paper web from a slitting machine, for example, on a paper drum 74 sleeved on the drive shaft 22, the height of the paper roll is adapted to the height of the operator, thereby making it more convenient for the operator to operate.

[0059] According to an embodiment of the present disclosure, the damping device 50 may be a magnetic powder damper. The magnetic powder damper used in the present disclosure as the damping device can better respond to the damping control signal of the control unit 60 and facilitate damping control / speed control of the drive shaft 22.

[0060] The above are only preferred embodiments of the present disclosure. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present disclosure. These improvements and modifications should also be regarded as the protection scope of the present disclosure.
