Description

Technical Field

[0001] This application relates to the field of cigarette manufacturing technology, and in particular to a rubber cylinder for cigarette manufacturing. Background Technology

[0002] In the cigarette manufacturing industry, tipping paper, as a crucial component, directly impacts the appearance and quality of cigarettes through its bonding quality. Tipping paper is a vital material in cigarette production; it requires adhesive before use. The adhesive-coated tipping paper sheets then wrap the paired filters and cigarette packs together to form two parallel long cigarettes. The adhesive, as a key material for achieving a tight bond between the tipping paper and the cigarette, requires stable performance. Existing systems use a control roller that rotates in conjunction with the application roller. The cigarette rolling machine includes an adhesive cylinder that rotates around one end and is mounted on the machine. With the cigarette industry's increasing demands for product quality and production efficiency, and the continued growth in market demand for high-quality cigarettes, solving the problem of adhesive solidification and deterioration in tipping paper is urgently needed.

[0003] In this related technology, the storage and use environment of the adhesive in the glue tank is usually quite open, making the adhesive susceptible to changes in external temperature. Existing adhesive storage and use devices generally lack effective protection and regulation mechanisms. When environmental conditions change, it is impossible to take timely measures to protect the adhesive, thus affecting the bonding effect of the tipping paper. This not only increases the defect rate in cigarette production and raises production costs, but may also negatively impact the company's brand image. Utility Model Content

[0004] Therefore, it is necessary to provide a glue cylinder for cigarette production, which addresses the problems that traditional glue cylinders typically have a relatively open storage and usage environment, lack effective protection and regulation mechanisms, and cannot take timely measures to protect the glue when environmental conditions change, thus affecting the bonding effect of the splicing paper.

[0005] According to one aspect of this application, a glue cylinder for cigarette production is provided, comprising a glue cylinder including an opening; a glue control roller rotatably mounted inside the glue cylinder; and an upper glue roller rotatably connected to the glue cylinder and located at the opening, wherein the glue control roller is located on the side of the upper glue roller opposite to the opening and abuts against the upper glue roller; a slide is provided at the opening on both radially sides of the upper glue roller, wherein the end of the slide away from the upper glue roller is inclined in the direction of gravity relative to the end closer to the upper glue roller, and a cover plate is slidably mounted on the slide; the end of the cover plate facing the upper glue roller abuts against the upper glue roller, and the end of the cover plate opposite to the upper glue roller is provided with a vertical plate that fits against the outer wall of the glue cylinder.

[0006] In one embodiment, a dustproof frame located on both sides of the upper glue roller is slidably mounted on the outer wall of the glue cylinder. The dustproof frame includes an arc plate for shielding the upper glue roller.

[0007] In one embodiment, the control roller has a drive shaft in the middle, and the control roller is movably mounted in the glue cylinder via the drive shaft; the top roller has a driven shaft in the middle, and the top roller is movably mounted in the opening via the driven shaft; a linkage belt is connected to the drive shaft, and the drive shaft is connected to the driven shaft via the linkage belt.

[0008] In one embodiment, the glue cylinder for cigarette production further includes a motor, the output end of which is connected to a drive belt, and the motor is connected to the drive shaft via the drive belt.

[0009] In one embodiment, a T-slot is provided on the slide table, and a slide seat is provided at the bottom of the cover plate. The cover plate is slidably installed in the T-slot via the slide seat. A first handle is also provided on the outer wall of the cover plate.

[0010] In one embodiment, a first magnetic plate is installed on the outer wall of the glue cylinder, and a second magnetic plate with opposite magnetism to the first magnetic plate is installed on the inner wall of the vertical plate.

[0011] In one embodiment, a control panel is provided on the outer wall of the glue cylinder; and an observation window is provided on the cover plate.

[0012] In one embodiment, a humidity sensor is installed inside the glue cylinder, and a humidification device for controlling the humidity inside the glue cylinder is installed on the outer wall of the glue cylinder; a temperature sensor is installed inside the glue cylinder, and a heating tube is also provided inside the glue cylinder.

[0013] In one embodiment, a track is provided on the outer wall of the glue cylinder, and a limiting groove is provided on the inner wall of the dustproof frame. The dustproof frame is slidably mounted on the glue cylinder through the limiting groove. A second handle is also provided on the outer wall of the dustproof frame.

[0014] In one embodiment, the dustproof rack is made of acrylic sheet.

[0015] In one embodiment, a discharge plate is movably disposed on the outer wall of the glue cylinder; and a stop block is disposed at the end of the track facing the glue roller.

[0016] This application has the following beneficial effects:

[0017] Temperature and humidity have a significant impact on the use and storage of tipping adhesive. To prevent the adhesive from solidifying and deteriorating during use, a cover plate is installed on top of the adhesive cylinder to essentially isolate it from outside air. Humidity and temperature sensors are installed inside the cover plate to monitor internal temperature and humidity. In addition, the inclined cover plate not only scrapes the glue roller but also diverts the scraped adhesive. A dust cover effectively prevents dust from contaminating the adhesive. This device has a simple structure, is easy to install and maintain, and effectively reduces the solidification and deterioration of tipping adhesive during use, improving the quality of cigarette splicing.

[0030] See Figures 1-4 , Figure 1 This application shows an overall structural diagram of a glue cylinder for cigarette production according to an embodiment of the present application. The glue cylinder 1 includes an opening 2. A glue control roller 3 is movably installed inside the glue cylinder 1, and an upper glue roller 4 that is in contact with the glue control roller 3 is movably installed in the opening 2. A slide 11 is provided at the opening 2 on both radial sides of the upper glue roller 4. The end of the slide 11 away from the upper glue roller 4 is inclined in the direction of gravity relative to the end closer to the upper glue roller 4. A cover plate 12 is slidably installed on the slide 11. The end of the cover plate 12 facing the upper glue roller 4 abuts against the upper glue roller 4, and the end of the cover plate 12 away from the upper glue roller 4 is provided with a vertical plate 15 that is in contact with the outer wall of the glue cylinder 1. Dustproof frames 25 located on both sides of the upper glue roller 4 are slidably installed on the outer wall of the glue cylinder 1. The dustproof frames 25 include an arc plate 26 for shielding the upper glue roller 4.

[0031] During operation, the equipment first places the glue into the glue tank 1. Then, using the first handle 16, the cover plate 12 is slid upwards along the slide table 11. When the second magnetic plate 18 and the first magnetic plate 17 are attracted together, the cover plate 12 is installed, and at this time, the end of the cover plate 12 facing the upper glue roller 4 abuts against the upper glue roller 4. Then, using the second handle 30, the dustproof frame 25 is installed onto the track 27, and the dustproof frame 25 is slid upwards along the track 27 towards the upper glue roller 4 until the dustproof frame 25 is in contact with the stop block 29. Then, the motor 8 is started. During operation, when the humidity sensor 21 detects that the humidity inside the glue tank 1 is lower than the first threshold, the humidification device 22 is activated to input moist gas into the glue tank 1. When the temperature sensor 23 detects that the temperature inside the glue tank 1 is lower than the third threshold, the heating tube 24 is activated to heat the glue inside the glue tank 1.

[0032] See Figures 3-4 The control roller 3 has a drive shaft 5 in the middle, and the control roller 3 is movably installed in the glue cylinder 1 through the drive shaft 5; the upper glue roller 4 has a driven shaft 6 in the middle, and the upper glue roller 4 is movably installed in the opening 2 through the driven shaft 6; the drive shaft 5 is connected to the linkage belt 7, and the drive shaft 5 is connected to the driven shaft 6 through the linkage belt 7.

[0033] In some embodiments, under the action of the linkage belt 7, the control roller 3 and the top roller 4 rotate synchronously. Since the control roller 3 and the top roller 4 are bonded together, the glue on the control roller 3 is transferred to the outer surface of the top roller 4 through contact adhesion. The tipping paper is conveyed to the top of the top roller 4 by external equipment and bonded to its top. When the top roller 4 rotates clockwise, the tipping paper is conveyed from left to right, and the cover plate 12 located on the left side of the top roller 4 scrapes the glue on the outer surface of the top roller 4 to prevent excessive glue from affecting the bonding effect. At this time, the scraped glue flows back into the glue cylinder 1 along the inclined inner wall of the cover plate 12.

[0034] When the glue roller 4 rotates counterclockwise, the paper is fed from right to left, and the cover plate 12 located on the right side of the glue roller 4 scrapes the glue on the outer surface of the glue roller 4 to prevent excessive glue from affecting the bonding effect. At this time, the scraped glue flows back into the glue cylinder 1 along the inclined inner wall of the cover plate 12.

[0035] See Figures 3-4 It also includes a motor 8, the output end of which is connected to a drive belt 9, and the motor 8 is connected to the drive shaft 5 through the drive belt 9.

[0036] In some embodiments, in order to drive the control roller 3 and the application roller 4 to rotate synchronously, the motor 8 is connected to the drive shaft 5 via the drive belt 9.

[0037] In some embodiments, in the prior art, some glue cylinders 1 use frictional engagement between the glue control roller 3 and the glue application roller 4, instead of using a linkage belt 7. When the glue viscosity is low, this design is prone to slippage, resulting in poor stability and affecting the bonding effect of the splicing paper.

[0038] See Figures 2-3 The slide table 11 is also provided with a T-shaped groove 13, and the bottom of the cover plate 12 is provided with a slide seat 14. The cover plate 12 is slidably installed in the T-shaped groove 13 through the slide seat 14. The outer wall of the cover plate 12 is also provided with a first handle 16.

[0039] In some embodiments, in order to ensure that the cover plate 12 is movably mounted on the slide table 11 and to further improve the stability during sliding, a structure of mutually cooperating slide seat 14 and T-slot 13 is designed.

[0040] In some embodiments, a first handle 16 structure is designed to facilitate the pulling of the cover plate 12 during disassembly and assembly.

[0041] See Figures 2-3 A first magnetic plate 17 is installed on the outer wall of the glue cylinder 1, and a second magnetic plate 18 with opposite magnetism to the first magnetic plate 17 is installed on the inner wall of the vertical plate 15.

[0042] In some embodiments, when the cover plate 12 blocks the opening 2, a first magnetic plate 17 and a second magnetic plate 18 with opposite magnetic properties are designed to prevent the cover plate 12 from accidentally sliding down the slide table 11. During operation, the cover plate 12 is tightly attached to the outer wall of the glue cylinder 1 by the second magnetic plate 18.

[0043] In some embodiments, the end of the cover plate 12 facing the upper glue roller 4 is provided with a chamfer. This design can scrape the outer wall of the upper glue roller 4 to avoid excessive glue affecting the bonding effect of the splicing paper.

[0044] See Figure 1 and Figure 3 A control panel 10 is provided on the outer wall of the glue cylinder 1; an observation window 19 is provided on the cover plate 12.

[0045] In some embodiments, a control panel 10 is designed to control the operation of the equipment during operation. An observation window 19 is designed to facilitate the operator's observation of the internal working conditions and glue status of the glue tank 1.

[0046] See Figure 2 and Figure 4 The glue cylinder 1 is equipped with a humidity sensor 21 inside, and a humidification device 22 for controlling the humidity inside the glue cylinder 1 is installed on the outer wall of the glue cylinder 1; a temperature sensor 23 is installed inside the glue cylinder 1, and a heating tube 24 is also installed inside the glue cylinder 1.

[0047] In some embodiments, under high-temperature conditions, the moisture in the adhesive evaporates more quickly, leading to increased adhesive concentration, increased viscosity, and decreased fluidity, thereby accelerating the solidification and deterioration process. Conversely, under low-temperature conditions, the adhesive's activity decreases, potentially resulting in layering, clumping, and other phenomena, which also affect its normal use.

[0048] In some embodiments, a humidity sensor 21 is designed to monitor the humidity inside the glue tank 1 in real time. When the humidity sensor 21 detects that the humidity inside the glue tank 1 is lower than a first threshold, the humidification device 22 is activated to input humidifying gas into the glue tank 1. When the humidity sensor 21 detects that the humidity inside the glue tank 1 has reached a second threshold, the humidification device 22 is turned off.

[0049] In some embodiments, a temperature sensor 23 is designed to monitor the temperature inside the glue tank 1 in real time. When the temperature sensor 23 detects that the temperature inside the glue tank 1 is lower than a third threshold, the heating tube 24 is activated to heat the glue inside the glue tank 1. When the glue control roller 3 rotates, the glue can be stirred. When the temperature sensor 23 detects that the temperature inside the glue tank 1 reaches a fourth threshold, the heating tube 24 is turned off.

[0050] The first threshold, the second threshold, the third threshold, and the fourth threshold are all values ​​set by those skilled in the art when dealing with the device and in combination with actual needs.

[0051] See Figures 1-3 The outer wall of the glue cylinder 1 is provided with a track 27, and the inner wall of the dustproof frame 25 is provided with a limiting groove 28. The dustproof frame 25 is slidably mounted on the glue cylinder 1 through the limiting groove 28. A second handle 30 is also provided on the outer wall of the dustproof frame 25.

[0052] In some embodiments, to facilitate disassembly and maintenance of the equipment, the dust cover 25 is slidably mounted on the glue cylinder 1 via the limiting groove 28. A second handle 30 structure is designed to facilitate sliding of the dust cover 25.

[0053] During disassembly, first pull the second handle 30 away from the upper rubber roller 4. After the dust cover 25 is disengaged from the track 27, the cover plate 12 is then disassembled.

[0054] See Figure 1 and Figures 3-4 The dustproof rack 25 is made of acrylic sheet.

[0055] In some embodiments, the dustproof frame 25 is made of transparent acrylic sheet to facilitate observation of the working state and glue form of the glue roller 4 inside the arc plate 26 during operation.

[0056] See Figure 2 and Figure 4 A discharge plate 20 is also movably installed on the outer wall of the glue cylinder 1; a stop block 29 is also installed at the end of the track 27 facing the upper glue roller 4.

[0057] In some embodiments, an openable discharge plate 20 is designed to facilitate cleaning of the inside of the glue cylinder 1 during non-operation periods. When the dustproof frame 25 is installed, a stop block 29 structure is designed to limit its movement and prevent the arc plate 26 from abutting against the glue roller 4 and interfering with its rotation.

[0058] In some embodiments, when the dust cover 25 is in contact with the stop block 29, the arc plate 26 is in the optimal position and provides protection for the top roller 4, preventing dust or tobacco debris in the air from sticking to the top roller 4.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
