Description

Technical Field

[0001] This utility model relates to the field of tobacco processing technology, and in particular to a paper feeding force adjustment device and a cigarette rolling machine. Background Technology

[0002] The tension adjustment of the tipping paper in a cigarette rolling machine is mainly achieved by the suction roller adsorbing the tipping paper, thus generating tension in the tipping paper section between the balance box and the second feed roller. However, the tension of the tipping paper before entering the balance box is entirely provided by the tipping paper brake. Under the set conveying parameters, the tension provided by the tipping paper brake cannot be adjusted, resulting in an unstable running state of the tipping paper before entering the balance box. After entering the balance box, the axial adjustment of the tipping paper by the balance box may fail to correct the deviation, causing the tipping paper to not adhere well to the suction roller, leading to tension adjustment failure. This, in turn, results in uneven glue application on the tipping paper, making it prone to bubbles and wrinkles during cigarette splicing. It may also cause large axial displacement of the tipping paper, making it prone to flipping over when passing through the paper guide device. Utility Model Content

[0031] The embodiments of this utility model are described in detail below.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0032] like Figures 1-3As shown, this utility model provides a paper feeding force adjustment device, including a mounting plate 1, an adjusting member 520, and a drive assembly. The mounting plate 1 is fixedly connected to the body of a cigarette machine. The mounting plate 1 is provided with a mounting groove 13 and multiple paper roller mounting holes 11. The paper roller mounting holes 11 are used to install paper rollers, which are used to convey feeding paper along a first motion trajectory. The number of paper roller mounting holes 11 depends on the number of paper rollers. In this embodiment, there are two paper rollers, corresponding to two paper roller mounting holes 11. The adjusting member 520 can rotate around an adjusting axis and form a second motion trajectory, which intersects with the first motion trajectory. The adjusting member 520 moves relative to the mounting plate 1 along the second motion trajectory, and the first and second motion trajectories intersect, thereby allowing the adjusting member 520 to contact the feeding paper and change the motion trajectory of the feeding paper, thereby changing the wrap angle between the feeding paper and the paper roller, and thus changing the tension of the feeding paper.

[0033] Further, the drive assembly includes a cylinder 500, a first control valve 210, a second control valve 220, an actuation valve 300, a first pilot-operated flow regulating valve 410, and a second pilot-operated flow regulating valve 420. The cylinder 500 is installed in the mounting groove 13. The cylinder 500 is driven by the drive assembly, which in this embodiment is a hydraulic drive system or a pneumatic drive system. The output shaft of the cylinder 500 is connected to the adjusting member 520, and the axis of the output shaft of the cylinder 500 is the adjusting axis. That is, the adjusting member 520 rotates around the output shaft axis of the cylinder 500 and forms a second motion trajectory. The pressure medium source is connected to the pressure port of the actuation valve 300. The pressure medium can be compressed air or hydraulic oil, and the corresponding pressure medium source is an air source or an oil pump. In this embodiment, the pressure medium is preferably compressed air, and the pressure medium source is a compressed air pipeline or a compressed air tank. Actuating valve 300 is used to change the flow direction of the pressure medium. The actuating valve has a shut-off position, a first working position, and a second working position. First control valve 210 is used to cut off or open the control path of the first working position of actuating valve 300, where the pressure medium flows in a first direction. Second control valve 220 is used to cut off or open the control path of the second working position of actuating valve 300, where the pressure medium flows in a second direction, opposite to the first direction. The inlet of the first pilot-operated flow regulating valve 410 is connected to the first interface of actuating valve 300, the pilot port is connected to the second interface of actuating valve 300, and the outlet is connected to one of the inlets of cylinder 500. The inlet of the second pilot-operated flow regulating valve 420 is connected to the second interface of actuating valve 300, the pilot port is connected to the first interface of actuating valve 300, and the outlet is connected to the other inlet of cylinder 500. The first and second ports of the actuating valve 300 are connected to the two inlets of the cylinder 500 via the first pilot-operated flow regulating valve 410 and the second pilot-operated flow regulating valve 420, respectively. The flow direction of the pressure medium is the same as the unidirectional flow direction of the first pilot-operated flow regulating valve 410 and the second pilot-operated flow regulating valve 420. Both the first control valve 210 and the second control valve 220 are connected to the pressure medium source and are normally open. By adjusting the first control valve 210 or the second control valve 220 to close, the pressure medium reaches the actuating valve 300, causing the actuating valve 300 to switch to the first or second working position. The pressure medium enters the cylinder 500 from one of the first and second ports, while the other is used for pressure medium return, thereby changing the position of the regulating element 520 and completing the adjustment.

[0034] Specifically, when using the paper loading force adjustment device in this embodiment, the actuating valve 300 is in the cut-off position when no operation is performed. Therefore, a pressure difference cannot be formed at its first and second interfaces, thus preventing the adjustment element 520 from rotating around the output shaft of the cylinder 500. Furthermore, due to the first pilot-operated flow control valve 410 and the second pilot-operated flow control valve 420, the pressure medium at the two inlets of the cylinder 500 will not flow back, thereby ensuring that the position of the adjustment element 520 remains unchanged under a certain load. In this embodiment, the cylinder 500 can be a pneumatic cylinder or a hydraulic cylinder, depending on the type of pressure medium. In this embodiment, the pressure medium is compressed air; therefore, the cylinder 500 is preferably a swing cylinder. When the position of the regulating element 520 needs to be changed, the first control valve 210 or the second control valve 220 is closed, and the control path of the corresponding first working position or second working position is opened, so that the actuating valve 300 is switched to the first working position or the second working position. In this embodiment, the switching to the first working position is taken as an example. The pressure medium enters the cylinder 500 from the first port of the actuating valve 300 through the first pilot flow regulating valve 410. At the same time, the pressure medium at the first port enters the second pilot flow regulating valve 420 through the pilot path of the second pilot flow regulating valve 420. Thus, the pressure medium in the cylinder 500 passes through the pilot valve and the flow regulating path of the second pilot flow regulating valve 420 in sequence, and then flows back from the second port of the actuating valve 300 and is discharged to the atmosphere or oil sump. After the position of the regulating component 520 is adjusted to the correct position, the first control valve 210 is restored to the normally open state, the actuating valve 300 is switched to the shut-off position, the pressure at the first interface and the second interface is zero or there is no pressure difference, and the pressure medium in the cylinder 500 cannot pass through the first pilot flow regulating valve 410 and the second pilot flow regulating valve 420, ensuring that the position of the regulating component 520 does not change due to the load.

[0035] The actuating valve 300 should include at least three working positions and four ports. In this embodiment, the actuating valve 300 is selected as a three-position five-way valve, such as a three-position five-way center-closed valve, a three-position five-way center-relief valve, or a three-position five-way center-pressure valve. When the actuating valve 300 is a three-position five-way center-closed valve, the pressure medium cannot pass through in the closed position, and there is no pressure difference between the first port and the second port, thus ensuring that the position of the regulating element 520 does not change. When the actuating valve 300 is a three-position five-way center-relief valve, the pressure medium cannot pass through in the closed position, and the pressure at both the first port and the second port is 0, which also ensures that the position of the regulating element 520 does not change. When the actuating valve 300 is a three-position five-way center-pressure valve, the pressure medium is supplied to both the first port and the second port simultaneously in the closed position, and there is no pressure difference between the first port and the second port, which also ensures that the position of the regulating element 520 does not change. Since the regulating element 520 bears a unidirectional load during use, and considering that the pressure medium in this embodiment is compressed gas, and taking into account factors such as leakage at the connection joint and large pressure changes, both the three-position five-way center-sealed valve and the three-position five-way center-pressure valve have pressure at the first and second ports when in the shut-off position. This pressure will still slightly change the position of the regulating element 520 over time. Therefore, the actuating valve 300 in this embodiment is preferably a three-position five-way center-relief valve, which has no pressure at the first and second ports when in the shut-off position, to ensure that the position of the regulating element 520 can be maintained for a long time.

[0036] Furthermore, in this embodiment, the pressure medium is compressed gas, the actuation valve 300 is a pneumatically controlled valve, and both the first control valve 210 and the second control valve 220 are manual two-position two-way valves. Therefore, the drive assembly does not require electrical connection and can better adapt to environments without power supply. The drive assembly also includes a gas source switch 100, which is used to connect or disconnect the gas supply main pipeline between the first control valve 210, the second control valve 220, and the actuation valve 300. A switch mounting hole 14 is provided on the mounting plate 1, and the gas source switch 100 is installed in the switch mounting hole 14 to facilitate operation by the operator.

[0037] Alternatively, please refer to Figures 1-2 As shown, the mounting plate 1 is also provided with two button mounting holes 12. The buttons of the first control valve 210 and the second control valve 220 are respectively installed in the two button mounting holes 12, so that the operator can intuitively observe the position of the adjusting component 520 while operating, and selectively adjust the buttons of the first control valve 210 and the second control valve 220 according to the position of the adjusting component 520.

[0038] Specifically, the drive assembly also includes a swing arm 510. The cylinder 500 is installed in the mounting groove 13 and fixedly connected to the mounting plate 1. The two inlets of the cylinder 500 are respectively connected to the first pilot-operated flow regulating valve 410 and the second pilot-operated flow regulating valve 420. One end of the swing arm 510 is fixedly connected to the output shaft of the cylinder 500, and the other end is fixedly connected to the adjusting member 520. The adjusting member 520 is a shaft-like structure or a rod-like structure, and in this embodiment, it is preferably a shaft-like structure. During the adjustment process, the adjusting member 520 rotates around the output shaft of the cylinder 500 via the swing arm 510. That is, the adjusting member 520 moves around the axis of the output shaft of the cylinder 500 along a second motion trajectory. When the adjusting member 520 moves to the position where the first motion trajectory and the second motion trajectory intersect, the adjusting member 520 comes into contact with the splicing paper. As the adjusting member 520 continues to move, the adjusting member 520 slides relative to the splicing paper while changing the conveying trajectory of the splicing paper, thereby changing the wrap angle between the splicing paper and the paper roller, and thus changing the tension of the splicing paper. The adjusting member 520 is fixedly connected to the swing arm 510, making the friction between the adjusting member 520 and the splice paper a sliding friction, which is more conducive to improving the frictional force between the splice paper and the adjusting member 520. The length of the adjusting member 520 is greater than the width of the splice paper to prevent the splice paper from curling or flipping when passing through the adjusting member 520. In addition, a friction part can be provided on the outer periphery of the adjusting member 520 to increase the frictional force between the adjusting member 520 and the splice paper. The friction part can be a pattern on the outer periphery of the adjusting member 520 or a high-friction coefficient material such as leather, rubber, or plastic pasted on the outer periphery of the adjusting member 520. Similarly, a friction part is also provided on the outer periphery of the paper roller to increase the frictional force between the paper roller and the splice paper. The friction part can be a pattern on the outer periphery of the adjusting member 520 or a high-friction coefficient material such as leather, rubber, or plastic pasted on the outer periphery of the adjusting member 520. Providing a friction part on the outer periphery of the paper roller effectively prevents slippage during the feeding of the splice paper, which would reduce the splice paper force.

[0039] Optionally, such as Figure 2 As shown, to facilitate installation, a slide rail 131 is also provided on the side wall of the mounting groove 13. The cylinder body 500 slides in conjunction with the slide rail 131, which guides the installation on the one hand and ensures the installation accuracy of the cylinder body 500 on the other hand.

[0040] This utility model provides a cigarette rolling machine, including the tipping paper force adjustment device in this embodiment, which makes the tension of the tipping paper adjustable during the conveying process, ensuring the stability of the tipping paper during the conveying process, thereby avoiding the occurrence of defective cigarettes due to the unstable state of the tipping paper.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
