Description

Technical Field

[0001] The invention belongs to the technical field of tobacco manufacturing, and in particular relates to a device and method for controlling the curling force of tipping paper of a cigarette making machine. Background Art

[0002] The cigarette rolling and splicing production process can be divided into three parts: feeding into strips, rolling paper forming and filter tipping. The filter tipping part is to stick and wrap the tipping paper on the cut filters and cigarettes to form a complete cigarette.

[0003] After the tipping paper passes through the splicing joint inspection, it enters the gluing system through a scraper and a paper feed roller to complete the gluing and enter the subsequent process. Since the gluing surface of some tipping papers is relatively smooth, the scraper alone cannot make the tipping paper sufficiently curled and improve the roughness of the gluing surface, resulting in poor latex adhesion on the gluing surface, which affects the quality of cigarette splicing, greatly affects production efficiency, increases material consumption, and makes the quality pass rate low. Therefore, how to design a cigarette machine tipping paper curling force control device and method to improve the latex adhesion of the gluing surface of the tipping paper has become a technical problem that technicians in this field urgently need to solve.

[0022] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0023] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0024] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0025] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0026] like Figure 1 As shown, an embodiment of the present invention provides a curling force control device for tipping paper of a cigarette making machine, which includes a driving member, a guide roller 21, a mounting frame 11, and a controller. The mounting frame 11 is arranged upstream of the scraper, and a slider 12 is arranged at one end of the mounting frame 11 for sliding up and down; the guide roller 21 is arranged on the slider 12, and the guide roller 21 is used to contact the tipping paper, and the driving member is used to drive the slider 12 to move up and down; the driving member is electrically connected to the controller, and the controller is electrically connected to a splicing joint detection device of the cigarette making machine.

[0027] Furthermore, a sliding hole is vertically provided on the mounting frame 11, and the sliding hole is slidably matched with the slider 12, and the guide roller 21 is connected to the upper end of the slider 12, thereby better realizing the up and down sliding setting of the slider 12 in the sliding hole of the mounting frame 11.

[0028] Preferably, the guide roller 21 is detachably connected to the slider 12, so that the guide roller can be easily replaced or repaired.

[0029] Specifically, the driving member is a cylinder 31, so that the sliding block is driven by the cylinder to slide up and down in the sliding hole, and the structure of the driving member is relatively simple.

[0030] In other embodiments, the driving member may also be a motor, which is connected to the slider through a rack and pinion mechanism, that is, a gear is provided on the output shaft of the motor, and a rack meshing with the gear is vertically provided on one side of the slider, so that the motor is used to drive the slider to move up and down.

[0031] Preferably, the driving member is fixed on the mounting frame 11. Specifically, the controller can be integrated into the control system of the cigarette making machine.

[0032] Furthermore, at least two mounting holes 13 are provided on the mounting frame 11, so that the mounting frame and the cigarette making machine can be conveniently connected in a detachable manner through the mounting holes, and the connection between the mounting frame and the cigarette making machine is also more firm and reliable.

[0033] Specifically, there are four mounting holes 13, which are arranged on the mounting frame in pairs, so as to improve the connection reliability between the mounting frame and the cigarette making machine. It can be understood that since the guide roller is arranged upstream of the scraper, the tipping paper passes through the guide roller after being detected by the splicing detection device, and then enters the next process after being curled by the scraper.

[0034] The embodiment of the present invention also provides a method for controlling the curling force of tipping paper of a cigarette making machine, which comprises:

[0035] When the splicing joint detection device detects that there is no splicing joint on the tipping paper, the controller controls the driving member to move, drive the slider to move upward, and thus drive the guide roller to move upward to increase the tension of the tipping paper and increase the contact pressure between the tipping paper and the scraper.

[0036] Furthermore, the cigarette making machine tipping paper curling force control method also includes: when the splicing joint detection device detects that there is a splicing joint on the tipping paper, the controller controls the driving member to move, and drives the guide roller 21 to move downward through the slider 12 to reduce the tension of the tipping paper and reduce the contact pressure between the tipping paper and the scraper.

[0037] In one embodiment, when the splicing joint detection device detects that there is a splicing joint on the tipping paper, the controller controls the driving member to move, driving the guide roller 21 to move downward along with the slider 12 until the guide roller is lowered to a position where it does not contact the tipping paper, which can also be called the initial position or the non-working position, so as to reduce the tension of the tipping paper to the initial state. This can not only further reduce the pressure of the tipping paper when passing through the scraper, but also avoid the pressure generated when the guide roller contacts the splicing joint, thereby better avoiding fracture at the splicing joint, and further effectively avoiding the cigarette making machine from stopping due to fracture of the tipping paper.

[0038] The cigarette making machine tipping paper curling force control device and method provided by the embodiment of the present invention, when in use, when the splicing joint detection device detects that there is no splicing joint on the tipping paper, a signal is transmitted to the controller, and then the controller controls the driving member to move, and drives the guide roller 21 to move upward through the slider 12, so as to increase the tension of the tipping paper, so that the wrap angle of the tipping paper becomes larger when passing through the scraper, so that the curling property of the tipping paper can be improved and become sufficiently curled, and at the same time, the pressure at the contact point between the tipping paper and the scraper is increased, so that the roughness of the gluing surface can be improved, that is, the gluing surface will become rougher after passing through the scraper, creating more favorable conditions for the adhesion of latex on the gluing surface, thereby effectively improving the latex adhesion of the gluing surface of the tipping paper, and then improving the splicing quality of cigarettes. When the splice detection device detects a splice on the tipping paper, it sends a signal to the controller, and then the controller controls the driving member to move, and drives the guide roller 21 to move downward through the slider 12 to reduce the tension of the tipping paper, reduce the wrap angle of the tipping paper when passing through the scraper, and reduce the pressure at the contact point between the tipping paper and the scraper, thereby effectively avoiding the splice from breaking due to excessive pressure when passing through the scraper.

[0039] The present invention can realize automatic control of the curling force of the tipping paper, which can not only better ensure the quality of the twisting and splicing of cigarettes, but also avoid the breakage of the tipping paper. It can be understood that the curling force of the tipping paper, that is, the pressure at the contact point between the tipping paper and the scraper when the tipping paper is curled on the scraper, can effectively avoid the splicing joint from breaking when passing through the scraper when the pressure is small; when the pressure is large, the scraper can be used to increase the roughness of the glue surface on the tipping paper; the size of the pressure can be flexibly set according to actual conditions. The splicing joint detection device detects whether there is a splicing joint on the tipping paper, which is an existing commonly used detection method and will not be repeated here.

[0040] The present invention partially transforms the cigarette making machine and, under the premise of ensuring the quality of cigarette splicing, better solves the problem of easy breakage of tipping paper during the splicing process, improves the operating efficiency and stability of the cigarette making machine, reduces material consumption, and at the same time, the modification range of the cigarette making machine is relatively small, reducing the learning cost of operation and maintenance.

[0041] Although some specific embodiments of the present invention have been described in detail by way of example, it will be appreciated by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It will be appreciated by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
