Description

Technical Field

[0001] The utility model belongs to the field of tobacco production equipment, and in particular relates to an automatic control device for tensioner equipment. Background Art

[0002] In the tobacco processing industry, reconstituted tobacco technology involves processing discarded tobacco stems, tobacco dust, and low-quality tobacco leaves from cigarette production to create reconstituted tobacco with quality similar to or even superior to natural tobacco. Reconstituted tobacco features excellent combustion properties, high filler content, and low tar content. Its primary purpose is to recycle tobacco waste generated during tobacco processing, improve the utilization rate of tobacco raw materials, and produce materials such as cigar wrappers. It represents a form of tobacco resource recycling.

[0003] However, the tension roller conveyor system used in traditional reconstituted tobacco production lines has significant shortcomings. The existing tensioner still relies on manual adjustment, which means that during production, operators must manually adjust the tension of the felt according to actual conditions to ensure the proper tension between the felt and the tension roller, requiring frequent attention during operation.

[0004] Secondly, felts are prone to misalignment during operation. When this misalignment impacts production progress, the current solution often involves stopping the machine, loosening the felt, and manually adjusting its position to a centered state. This approach not only increases downtime and reduces production efficiency, but also increases operator workload and safety risks.

[0005] In summary, providing a tensioning roller device that can dynamically adjust the tension of the felt and effectively prevent the felt from running off the track is of great significance for improving the production efficiency and stability of the reconstituted tobacco production line.

Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments.

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features.

[0034] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the conditions under which this application can be implemented. Therefore, they have no substantive technical significance. Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical content disclosed in this application without affecting the efficacy and purpose that can be achieved by this application.

[0035] Please refer to Figures 1 to 2 , the technical solution of the utility model is specifically described as a tensioner equipment automatic control device, and its specific structure includes: a first direction limit point 2, a second direction limit point 3, a moving unit 4, and a driving unit 5;

[0036] like Figure 1 As shown, compared with the prior art arrangement in which the tensioning roller 1 and the felt are relatively fixed, in the present application, as shown in this embodiment, both sides of the tensioning roller 1 are movably arranged on the moving unit 4, and the driving unit 5 is used to drive the tensioning roller 1 to move along the first direction on the moving unit 4. In the present application, the first direction described is the running direction of the felt. In other embodiments, the first direction can also be set in other directions;

[0037] In order to better dynamically adjust the tension of the blanket, the mobile unit 4 is provided with the first direction limit points 2 at both ends along the first direction to monitor the tension of the blanket;

[0038] At the same time, such as Figure 2As shown, the tensioning roller 1 is provided with second direction limit points 3 at both ends along the axial direction of the tensioning roller 1 for monitoring the deflection of the felt. In the present application, the second direction described is the axial direction of the tensioning roller 1. In other embodiments, the second direction may also be set in other directions.

[0039] It is understandable that, in the present application, the dynamic adjustment method of the conveying roller during the conveying of the blanket is as follows:

[0040] When the tensioning roller 1 moves on the moving unit 4 and moves to the first direction limit point 2, it means that the tension of the blanket is too large or too small and needs to be adjusted in time; at this time, the driving unit 5 adjusts the tension of the blanket by driving the two ends of the tensioning roller 1 to move synchronously along the first direction. At this time, the two ends of the tensioning roller 1 move synchronously to adjust the tension of the blanket;

[0041] When the felt deviates and one side deviates to the second direction limit point 3, it means that the deflection of the felt is too serious and needs to be adjusted in time; at this time, the driving unit 5 adjusts the deflection of the felt by driving one end of the tensioning roller 1 to move along the first direction alone. At this time, since the two ends of the tensioning roller 1 are set at an angle, the movement direction of the felt will be adjusted in the opposite direction according to the angle direction.

[0042] Preferably, the driving device of this embodiment is further limited. In this embodiment, in order to better drive the tensioning roller 1 to move, the number of the driving units 5 is two groups, and specifically, as shown in FIG. Figure 1 As shown, the movable units 4 are respectively arranged at both ends of the tensioning roller 1, and each driving unit 5 independently drives one end of the tensioning roller 1 to move along the first direction. Through the independent arrangement of two groups of driving units 5, the two sides of the tensioning roller 1 can be moved more flexibly and dynamically adjusted according to actual needs.

[0043] More preferably, the first direction limit point 2 of this embodiment is further limited. In this example, since the driving unit 5 is provided on both sides of the tensioning roller 1, in order to limit the movement of the tensioning roller 1, the first direction limit point 2 is provided at both ends of the moving unit 4 on both sides of the tensioning roller 1.

[0044] Furthermore, in order to better adjust the deflection of the blanket, such as Figure 2 As shown, in this example, a second direction correction point 6 is further provided on the tensioning roller 1 along the axial direction of the tensioning roller 1;

[0045] The second direction correction point 6 is arranged relative to the second direction limit point 3 and close to the center of the tensioning roller 1;

[0046] It can be understood that since the second direction correcting point 6 is arranged further on the inner side, during the specific operation, when the blanket is transported normally, it contacts the second direction correcting points 6 on both sides; when the blanket deviates, one side will not contact the second direction correcting point 6, thereby reminding to adjust the deviation. When the blanket deviates to the second direction limit point 3, the direction of movement of the blanket must be adjusted.

[0047] Preferably, the second direction limit point 3 and the second direction correcting point 6 in this embodiment are further defined. In this embodiment, the second direction correcting point 6 and the second direction limit point 3 are both photoelectric sensors;

[0048] Therefore, during the transportation of the blanket, when it is in the upright position, the photoelectric sensors of the second direction correction point 6 are blocked on both sides; when the blanket deviates, the photoelectric sensor of the second direction correction point 6 on one side receives the signal and even blocks the photoelectric sensor of the second direction limit point 3, thereby achieving the function of detecting the deviation of the blanket.

[0049] Preferably, the movable unit 4 of this embodiment is further limited. In this example, the movable unit 4 is specifically a slide rail assembly, which can facilitate the movement of the tensioning roller 1 along the first direction on the movable unit 4; in other embodiments, the movable unit 4 can also use other movable components.

[0050] Furthermore, the first direction limiting point 2 of this embodiment is further limited, such as Figure 1 As shown, in this example, the first direction limit point 2 is specifically selected as a contact sensor, which can facilitate the response to the need to adjust the tensioning force after the tensioning roller 1 moves and contacts in the first direction; in other embodiments, the first direction limit point 2 can also be selected from other sensor components.

[0051] Preferably, the driving device of this embodiment is further limited. In this embodiment, in order to better drive the tensioning roller 1 to move, in this embodiment, the driving unit 5 is specifically selected as a servo stepper motor. The servo stepper motor, as a combination of the characteristics of a stepper motor and a servo motor, has the advantages of full closed-loop control, precise position and speed control, simple parameter setting, high-speed response, and large torque output. In other embodiments, the driving device can also use other power sources.

[0052] More preferably, the driving device of this embodiment is further defined. In this embodiment, in order to better drive the tensioning roller 1 to move, as shown in FIG. Figure 1 As shown, in this embodiment, the driving unit 5, that is, the specific output end of the servo stepper motor is connected to the moving unit 4 through a screw rod 7, so as to drive the tensioning roller 1 to move along the first direction. The transmission method connected by the screw has the advantage of smooth transmission compared with belt drive, chain drive, etc.

[0053] Preferably, the automatic control device of the tensioner equipment provided in the present application also includes a control unit, which is electrically connected to the first direction limit point 2, the second direction limit point 3, and the drive unit 5. When tension and / or deflection occurs on the blanket, the drive unit 5 is controlled to dynamically adjust the tensioning roller 1. Specifically, the control unit can be composed of a programmable control chip such as a PLC or a single-chip microcomputer, which is not specifically limited in the present application.

[0054] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
