Description

Technical Field

[0001] This invention relates to the field of cigarette manufacturing technology, and more specifically, to a device for correcting the position of the adhesive on cigarette paper. Furthermore, this invention also relates to a cigarette machine incorporating the aforementioned device for correcting the position of the adhesive on cigarette paper. Background Technology

[0002] Inside the cigarette rolling machine, the belt pulley drives the belt to move at high speed within the cigarette gun guide rail. The belt drives the cigarette paper to move synchronously, and the tobacco bundle enters the cigarette gun guide rail at the same speed. After the glue gun applies glue to the edges of the cigarette paper, the cigarette gun guide rail uses its special shape to wrap the cigarette paper and tobacco bundle into a tobacco strip, ready for subsequent cutting and filter rod splicing processes.

[0003] To maintain the stability and consistency of cigarette pack forming, the glue position on the cigarette paper must be highly consistent, thus requiring online correction of the glue application position. Existing correction devices have the detection element located on the cigarette gun guide rail. However, because the cigarette paper is driven by friction on the conveyor belt, correction cannot be achieved on the conveyor belt itself. The correction wheel is located at the point where the cigarette paper enters the cigarette gun guide rail, allowing adjustment of the cigarette paper's position only before it enters the conveyor belt. Because the correction wheel is far from the detection element, the correction response speed is slow, the correction accuracy is low, and the glue application position of the cigarette paper fluctuates significantly, affecting the stability and consistency of cigarette pack forming, and ultimately impacting the quality of the cigarette outer tube and the operational stability of the cigarette rolling machine.

[0004] In conclusion, how to achieve rapid correction of the adhesive position on cigarette paper is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a device for correcting the glue application position of cigarette paper, which can adjust the height of the glue gun assembly in real time through the correction component, and the correction component is close to the detection element located at the glue application position, thereby realizing rapid correction of the glue application position of cigarette paper.

[0006] In addition, the present invention also provides a cigarette machine including the above-mentioned cigarette paper adhesive position correction device.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A device for correcting the position of adhesive on cigarette paper, comprising:

[0009] The detection element is located at the glue position on the cigarette gun guide rail and is used to detect the height of the cigarette paper edge relative to the upper end face of the cigarette gun guide rail in real time.

[0010] The correction component, whose movable end is connected to the glue gun assembly, is used to drive the glue gun assembly to move up and down along the height direction of the smoke gun guide rail;

[0011] The control device includes a detection element and a correction assembly, both of which are signal-connected to the control device. The control device is used to adjust the height of the glue gun assembly based on the real-time height of the cigarette paper edge measured by the detection element, so that the height difference between the glue gun assembly and the cigarette paper edge remains constant.

[0012] Preferably, the correction assembly includes a correction motor, a fixed mounting plate, and a sliding mounting bracket for mounting the glue gun assembly. The sliding mounting bracket is connected to the fixed mounting plate via an eccentric shaft, and the eccentric shaft is connected to the output shaft of the correction motor.

[0013] When the correction motor drives the eccentric shaft to rotate, the sliding mounting bracket slides up and down relative to the fixed mounting plate along the height direction of the smoke gun guide rail.

[0014] Preferably, one of the fixed mounting plate and the sliding mounting bracket is provided with a slide rail arranged along the height direction of the smoke gun guide rail, and the other is provided with a slider that engages with the slide rail.

[0015] Preferably, the sliding mounting bracket is rotatably connected to the glue gun bracket of the glue gun assembly, and the glue gun bracket is connected to the moving end of the glue gun rotation power assembly so as to drive the glue gun bracket to rotate relative to the sliding mounting bracket in a vertical plane.

[0016] Preferably, the glue gun rotation power assembly includes a cylinder bracket and a telescopic cylinder. The cylinder bracket protrudes from the surface of the sliding mounting bracket. The fixed end of the telescopic cylinder is hinged to the cylinder bracket, and the movable end of the telescopic cylinder is hinged to the glue gun bracket.

[0017] Preferably, the top end of the glue gun bracket is hinged to the telescopic cylinder, and the bottom end of the glue gun bracket is rotatably connected to the sliding mounting bracket.

[0018] A cigarette rolling machine includes a belt pulley assembly for conveying cigarette paper, a tobacco bundle conveying assembly for conveying tobacco bundles, a cigarette gun guide rail for wrapping the cigarette paper and the tobacco bundles into a cigarette stick, and a cigarette paper adhesive position correction device as described in any one of the above.

[0019] When the cigarette rolling machine is working, the detection element located at the glue application position detects the height of the cigarette paper edge in real time. The control device adjusts the height of the glue gun assembly through the correction component based on the real-time height of the cigarette paper edge, so that the height difference between the glue gun assembly and the cigarette paper edge remains constant, thereby keeping the glue application position of the cigarette paper relatively stable.

[0020] The cigarette paper gluing position correction device provided by the present invention can adjust the height of the glue gun assembly in real time through the correction component, so that the gluing position of the cigarette paper is relatively stable. At the same time, the distance between the correction component and the detection element located at the gluing position is close, which greatly improves the correction response speed and realizes rapid correction of the gluing position of the cigarette paper, which is beneficial to improving the stability and consistency of cigarette strip forming.

[0021] In addition, the present invention also provides a cigarette machine including the above-mentioned cigarette paper adhesive position correction device, which reduces the fluctuation of the cigarette paper adhesive position, improves the appearance quality of the cigarettes and the operational stability of the cigarette machine.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] The core of this invention is to provide a device for correcting the glue application position on cigarette paper. The height of the glue gun assembly can be adjusted in real time through the correction component, and the distance between the correction component and the detection element located at the glue application position is relatively close, thereby realizing rapid correction of the glue application position on the cigarette paper.

[0030] In addition, the present invention also provides a cigarette machine including the above-mentioned cigarette paper adhesive position correction device.

[0031] The cigarette paper adhesive position correction device provided by the present invention includes:

[0032] The detection element 301 is located at the glue position of the cigarette gun guide rail 30 and is used to detect the height of the cigarette paper edge relative to the upper end face of the cigarette gun guide rail 30 in real time.

[0033] The correction component 40 has its movable end connected to the glue gun assembly 20 and is used to drive the glue gun assembly 20 to move up and down along the height direction of the smoke gun guide rail 30.

[0034] The control device, the detection element 301, and the correction assembly 40 are all signal connected to the control device. The control device is used to adjust the height of the glue gun assembly 20 according to the real-time height of the cigarette paper edge measured by the detection element 301, so that the height difference between the glue gun assembly 20 and the cigarette paper edge remains constant.

[0035] The detection element 301 is located at the glue position of the cigarette gun guide rail 30. The detection element 301 is used to detect the height from the upper edge of the cigarette paper 01 to the upper end face of the cigarette gun guide rail 30. The detection element 301 can be located on the side of the cigarette gun guide rail 30 or above the cigarette gun guide rail 30. Its specific installation position is determined according to the height measurement principle or distance measurement principle of the detection element 301.

[0036] The detection element 301 can be set as a distance sensor or a height sensor. The specific type and detection accuracy of the detection element 301 are determined according to the height range of the cigarette paper edge in actual production, so as to ensure the correction accuracy of the correction component 40.

[0037] The correction component 40 is used to adjust the height of the glue gun assembly 20, so as to keep the height difference between the glue tip of the glue gun 201 and the edge of the cigarette paper consistent. The correction component 40 can be set as a common linear power mechanism such as an electric push rod or a cylinder.

[0038] The control device is used to receive the real-time height of the cigarette paper edge measured by the detection element 301, and accordingly control the correction component 40 to adjust the height of the glue gun assembly 20, thereby adjusting the height difference between the glue gun assembly 20 and the cigarette paper edge to a preset value.

[0039] It should be noted that the above preset value can be a fixed value or a range of values, which is determined according to the design and production parameters such as the specifications of the cigarette packs in actual production.

[0040] When the cigarette rolling machine is working, the detection element 301 located at the glue application position detects the height of the cigarette paper edge in real time. The control device adjusts the height of the glue gun assembly 20 through the correction component 40 according to the real-time height of the cigarette paper edge, so that the height difference between the glue gun assembly 20 and the cigarette paper edge remains constant, thereby keeping the glue application position of the cigarette paper 01 relatively stable.

[0041] In this embodiment, the correction component 40 can work with the detection element 301 to adjust the height of the glue gun assembly 20 in real time, so that the glue application position of the cigarette paper 01 is relatively stable. At the same time, the correction component 40 and the detection element 301 located at the glue application position are close to each other. Compared with the prior art where the correction wheel is located before the cigarette paper 01 enters the fabric belt 101, the correction response speed is greatly improved, and the rapid correction of the glue application position of the cigarette paper 01 is realized, which is conducive to improving the stability and consistency of cigarette strip forming.

[0042] Based on the above embodiments, the structure of the correction component 40 is defined, and the correction component 40 can be configured to include a correction motor 401, a fixed mounting plate 402 and a sliding mounting bracket 403 for mounting the glue gun assembly 20. The sliding mounting bracket 403 is connected to the fixed mounting plate 402 through an eccentric shaft 404, and the eccentric shaft 404 is connected to the output shaft of the correction motor 401.

[0043] When the correction motor 401 drives the eccentric shaft 404 to rotate, the sliding mounting bracket 403 slides up and down relative to the fixed mounting plate 402 along the height direction of the smoke gun guide rail 30.

[0044] Among them, the eccentricity and other dimensions of the eccentric shaft 404 determine the range of movement of the glue gun assembly 20 in the height direction, which needs to be determined according to the actual production needs; the type and power of the correction motor 401 are determined according to the correction accuracy requirements of the glue application position of the cigarette paper 01 in actual production.

[0045] In this embodiment, the eccentric shaft 404 can convert the rotation of the correction motor 401 into the up-and-down sliding of the sliding mounting bracket 403 in the height direction. Compared with driving the glue gun assembly 20 through a linear power mechanism, the control precision requirements of the power mechanism are lower, which is beneficial to reducing equipment costs.

[0046] Preferably, one of the fixed mounting plate 402 and the sliding mounting bracket 403 may be provided with a slide rail arranged along the height direction of the cigarette gun guide rail 30, and the other may be provided with a slider that engages with the slide rail. The sliding connection between the slide rail and the slider can limit the movement direction of the sliding mounting bracket 403 and prevent the sliding mounting bracket 403 from deviating from the height direction of the cigarette gun guide rail 30 during the up and down sliding process.

[0047] The specific shape, structure, size and distribution of the slide rail and the slide rail itself are determined with reference to existing technology based on factors such as the shape and size of the fixed mounting plate 402 in actual production, and will not be elaborated here.

[0048] Based on the above embodiments, the sliding mounting bracket 403 can be rotatably connected to the glue gun bracket 202 of the glue gun assembly 20, and the glue gun bracket 202 can be connected to the moving end of the glue gun rotation power assembly so as to drive the glue gun bracket 202 to rotate relative to the sliding mounting bracket 403 in the vertical plane.

[0049] Please refer to Figure 2 The glue gun bracket 202 is hinged to the sliding mounting bracket 403 via a connecting pin 203. The position of the connecting pin 203 is not limited, as long as it does not affect the normal operation of the glue gun 201.

[0050] The glue gun rotation power assembly can be a rotary power mechanism such as a rotary motor, or a linear power mechanism installed between the sliding mounting bracket 403 and the glue gun bracket 202, such as an electric push rod or a telescopic cylinder 406.

[0051] When the glue gun rotation power component moves, the glue gun bracket 202 rotates in the vertical plane relative to the sliding mounting bracket 403. This not only adjusts the glue dispensing and retraction of the glue gun 201, but also adjusts the glue dispensing angle of the glue gun 201 and fine-tunes the height difference between the glue dispensing tip of the glue gun 201 and the edge of the cigarette paper.

[0052] Preferably, the glue gun rotation power assembly may include a cylinder bracket 405 and a telescopic cylinder 406. The cylinder bracket 405 protrudes from the surface of the sliding mounting bracket 403. The fixed end of the telescopic cylinder 406 is hinged to the cylinder bracket 405, and the moving end of the telescopic cylinder 406 is hinged to the glue gun bracket 202.

[0053] When the telescopic rod of the telescopic cylinder 406 extends, it pushes the glue gun holder 202 to rotate towards the end closer to the glue gun guide rail 30, causing the glue gun 201 to extend forward, as shown below. Figure 2 As shown, at this time, the glue gun 201 is aligned with the vertical edge of the cigarette paper 01, and glue can be applied to the edge of the cigarette paper;

[0054] Conversely, when the telescopic rod of the telescopic cylinder 406 retracts, it drives the glue gun bracket 202 to rotate away from the cigarette gun guide rail 30, causing the glue gun 201 to retract backward. The glue gun 201 no longer contacts the vertical edge of the cigarette paper 01, and the glue application stops.

[0055] Preferably, the top end of the glue gun bracket 202 can be hinged to the telescopic cylinder 406, and the bottom end of the glue gun bracket 202 can be rotatably connected to the sliding mounting bracket 403. In this case, the power arm for rotating the glue gun bracket 202 is almost the height of the glue gun bracket 202, which helps to reduce the force exerted by the telescopic cylinder 406 on the glue gun bracket 202 and reduce the power consumption of the telescopic cylinder 406.

[0056] In addition to the above-mentioned cigarette paper adhesive position correction device, the present invention also provides a cigarette machine including the cigarette paper adhesive position correction device disclosed in the above embodiments. The cigarette machine includes a belt pulley assembly 10 for conveying cigarette paper 01, a tobacco bundle conveying assembly for conveying tobacco bundle 02, a cigarette gun guide rail 30 for wrapping cigarette paper 01 and tobacco bundle 02 into a cigarette stick, and the cigarette paper adhesive position correction device disclosed in the above embodiments. The structure of other parts of the cigarette machine is described in the prior art and will not be repeated here.

[0057] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0058] The foregoing has provided a detailed description of the cigarette rolling machine and its cigarette paper adhesive position correction device provided by the present invention. Specific examples have been used to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are merely for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
