Description

Technical Field

[0001] This invention relates to the tobacco production industry, and in particular to an online fine-tuning device for precisely controlling the glue supply of a shear-type glue supply device in cigarette production, belonging to the technical field of cigarette forming equipment. Background Technology

[0002] In the cigarette manufacturing process, the cigarette and filter are wrapped together as a whole by a tipping paper strip. This process is a crucial step in cigarette forming, and the wrapping effect of the tipping paper strip is directly related to the amount of glue supplied. Too much or too little glue will affect the appearance quality of the cigarette and result in it being rejected as waste. Therefore, controlling the amount of glue supplied is particularly important in the cigarette manufacturing process. Existing cigarette rolling machines adjust the gap between the glue cylinder and the large glue roller assembly and the small glue roller by adjusting the rotation angle of the glue cylinder fixed seat mounted on a fixed shaft and rotating around that shaft. This changes the amount of glue applied to the small glue roller, i.e., the glue supply, which in turn changes the amount of glue carried by the tipping paper strip passing around the outer circumference of the small glue roller. However, the reasonable range of glue supply is very narrow, and the range of adjustment for the gap between the large and small glue rollers is only a few micrometers. It is difficult to control precisely by manual adjustment. Therefore, adjusting the amount of glue supplied is extremely difficult and time-consuming. At the same time, because online adjustment cannot be achieved, it is necessary to repeatedly start and stop the machine, which affects production efficiency and generates a large number of waste products with each adjustment. Summary of the Invention

[0003] This invention proposes an online glue supply fine-tuning device. By finely adjusting the rotation angle of the eccentric shaft and the deflection angle of the glue cylinder seat, the gap between the glue cylinder and the large glue roller assembly and the small glue roller is precisely adjusted. This allows for precise adjustment of the glue amount on the small glue roller, i.e., the glue supply, ensuring accurate adjustment of the glue-carrying amount of the cork paper tape passing around the outer circumference of the small glue roller. This significantly reduces the difficulty and time required for adjustment, and also substantially reduces the number of defective products generated during online adjustment. The entire adjustment process can be completed without stopping the machine, while the machine is running online.

[0004] The present invention specifically adopts the following solution:

[0005] An online glue supply fine-tuning device includes a fine-tuning unit, a glue cylinder, a glue cylinder seat, a glue cylinder rotating shaft, a large glue roller, a small glue roller, and a wall plate. The fine-tuning unit includes a fine-tuning body, a fixed shaft, a needle roller bearing, an eccentric shaft, a bushing, an end cap, a rocker arm, a connecting rod, a slider, two bolt shafts, an adjusting seat, an adjusting screw, a locking nut, and a locking screw. The glue cylinder rotating shaft is fixed to the wall plate, one end of the glue cylinder seat is hinged to the glue cylinder rotating shaft, and the other end is supported on the fine-tuning unit. The large roller is partially submerged in the cylinder, with its shaft fixed to the cylinder via a bearing. The small roller is fixed to the wall plate via its bearing. The large and small rollers rotate relative to each other via their respective gears meshing at a constant speed ratio. The fixed shaft of the fine-tuning device is fixed to the wall plate, and the fine-tuning body is hinged to the fixed shaft. The needle roller bearing is mounted on a shaft offset from the center of an eccentric shaft. Both ends of the eccentric shaft are fixed shafts, and the side closest to the wall plate is supported by a bushing in the fine-tuning body housing the roller. On the innermost side of the two lugs of the needle bearing, there is a mounting hole for mounting the bushing. On the outermost side of the lug, there is also a corresponding mounting hole for mounting the outer fixed shaft of the eccentric shaft. The outer end of the eccentric shaft is a regular polygonal head that matches and fits into the regular polygonal hole at one end of the rocker arm. The end cap is attached to the outer end face of the regular polygonal head of the eccentric shaft and fixed to the threaded hole on the end face with a screw. The other end of the rocker arm is hinged to one end of the connecting rod through a bolt shaft. The other end of the connecting rod is hinged to the slider through another bolt shaft. The slider is placed in a groove of a matching shape opened for it in the fine-tuning body. The slider fits into the head of the threaded end of the adjusting screw. The adjusting screw and the adjusting seat are threaded together. The adjusting seat is fixed to the fine-tuning body. The locking nut and the adjusting screw are also threaded together and are used to lock the adjusting screw when the adjustment process is completed. The locking screw and the fine-tuning body are also threaded together to lock the fixed shaft, so that the fine-tuning body can no longer rotate.

[0006] Furthermore, the end of the small rubber roller's shaft closest to the wall plate is connected to a drive motor, which drives the roller to rotate.

[0007] The slider and the threaded end of the adjusting screw are specifically connected in a fine-neck screw connection. The threaded end of the adjusting screw has a fine-neck structure, and the head has a small-diameter thread. The diameter of the fine-neck is smaller than the diameter of the small-diameter thread. The fine-neck structure is located between the thread of the adjusting screw and the small-diameter thread on the head. The slider has a corresponding small-diameter threaded through-hole and an internal large-diameter blind hole coaxial with it. This blind hole can accommodate the small-diameter threaded head of the adjusting screw with a margin. When the adjusting screw rotates and moves longitudinally along its own axis, this connection structure can constrain the small-diameter threaded head of the adjusting screw to always remain within the large-diameter blind hole of the slider, thus allowing the slider to move synchronously with the axial movement of the adjusting screw, converting the rotational motion of the adjusting screw into the linear movement of the slider.

[0008] The head of the unthreaded end of the adjusting screw is a regular polygon, and through holes perpendicular to each side of the regular polygon are opened. A small steel rod can be inserted into the hole to rotate the adjusting screw, so as to adjust the glue supply online with precision.

[0009] The outer surface of the slider is engraved with arrows and text that correspond to changes in the amount of adhesive supplied, indicating the adjustment result corresponding to the fine-tuning direction.

[0010] The online fine-tuning process for glue supply is as follows: A small steel rod is inserted into the small hole on the side of the regular polygonal adjusting screw. Rotating the adjusting screw causes it to move axially, which in turn moves the slider synchronously. Through the connecting rod, the rocker arm rotates, forcing the eccentric shaft to rotate as well. Due to the eccentric structure of the eccentric shaft, the needle roller bearing mounted on it is slightly displaced upwards. This, in turn, causes the glue cylinder seat to deflect upwards by a small angle along its own axis. The glue cylinder and the large glue roller then shift slightly, and the gap between the large and small glue rollers decreases slightly, thus reducing the amount of glue applied to the small glue roller, i.e., the glue supply. Conversely, the glue supply increases as the large and small glue rollers move upwards. Insert a small steel rod into the small hole on the side of the regular polygonal adjusting screw, and rotate the adjusting screw in the opposite direction to make it move axially in the opposite direction. This causes the slider to move synchronously in the opposite direction. Through the connecting rod, the swing arm rotates in the opposite direction. The reverse rotation of the swing arm forces the eccentric shaft to rotate in the opposite direction as well. Due to the eccentric structure of the eccentric shaft itself, the needle roller bearing mounted on it is slightly adjusted downward by a displacement. This causes the rubber cylinder seat to deflect downward by a small angle with its own rotation axis. The rubber cylinder and the large rubber roller then shift slightly in the opposite direction. The gap between the large rubber roller and the small rubber roller increases slightly, and the amount of rubber applied to the small rubber roller, i.e., the amount of rubber supplied, increases accordingly.

[0011] By finely adjusting the rotation angle of the eccentric shaft and slightly adjusting the deflection angle of the glue cylinder seat, the gap between the glue cylinder and the large glue roller assembly and the small glue roller is precisely adjusted. This allows for precise adjustment of the glue application amount, i.e., the glue supply amount, of the small glue roller. Consequently, the glue-carrying amount of the tipping paper tape passing around the outer circumference of the small glue roller is accurately adjusted, greatly reducing the difficulty and time required for adjustment. It also significantly reduces the number of defective products generated during online adjustment. The entire adjustment process can be completed without stopping the machine and can be performed while the machine is running online. Attached Figure Description

[0025] like Figure 5 As shown, the three-dimensional structure of the glue cylinder 2 of the present invention is displayed.

[0026] Specific embodiments of the present invention

[0027] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the present invention relates to an online glue supply fine-tuning device and its fine-tuning device 1.

[0028] The online glue supply fine adjustment device mainly includes a fine adjustment device 1, a glue cylinder 2, a glue cylinder seat 3, a glue cylinder rotating shaft 4, a large glue roller 5, a small glue roller 6, and a wall panel 7.

[0029] The fine-tuning device 1 mainly includes a fine-tuning body 101, a fixed shaft 102, a needle roller bearing 103, an eccentric shaft 104, a bushing 105, an end cover 106, a rocker arm 107, a connecting rod 108, a slider 109, a bolt shaft 110, an adjusting seat 111, an adjusting screw 112, a locking nut 113, and a locking screw 114.

[0030] In this embodiment, the rotating shaft 4 of the glue cylinder is fixed to the wall panel 7. One end of the glue cylinder seat 3 is hinged to the rotating shaft 4, and the other end is supported on the needle roller bearing 103 of the fine-tuning device 1. The glue cylinder 2 is placed on the glue cylinder seat 3. The large glue roller 5 is partially immersed in the glue cylinder 2, and its rotating shaft is fixed to the glue cylinder 2 through a bearing. The small glue roller 6 is fixed to the wall panel 7 through its bearing. The large glue roller 5 and the small glue roller 6 rotate relative to each other through their respective gears meshing at a constant speed ratio. The fixed shaft 102 of the fine-tuning device 1 is fixed to the wall panel. 7. The fine-tuning body 101 is hinged to the fixed shaft 102. The needle roller bearing 103 is mounted on the shaft that is offset from the middle of the eccentric shaft 104. Both ends of the eccentric shaft 104 are fixed shafts. The side closest to the wall plate is supported by a bushing 105 on the inner side of the two side lugs provided by the fine-tuning body 101 that accommodate the needle roller bearing 103. The corresponding inner side lug has a mounting hole for mounting the bushing 105. The outer side lug also has a corresponding mounting hole for mounting the outer fixed shaft of the eccentric shaft 104. The outer end of the eccentric shaft 104 is a regular hexagonal head that matches and fits into the regular hexagonal hole at one end of the rocker arm 107. The end cap 106 is attached to the outer end face of the regular hexagonal head of the eccentric shaft 104 and fixed to the threaded hole on that end face with a screw. The other end of the rocker arm 107 is hinged to one end of the connecting rod 108 via a bolt shaft 110. The other end of the connecting rod 108 is hinged to the slider 109 via another bolt shaft 110. The slider 109 is placed on the fine-tuning body 101 for which a hole is provided. Within the matching groove, the slider 109 is fitted with the threaded end of the adjusting screw 112. The adjusting screw 112 is threadedly engaged with the adjusting seat 111, which is fixed to the fine-tuning body 101. The locking nut 113 is also threadedly engaged with the adjusting screw 112 and is used to lock the adjusting screw 112 at the end of the adjustment process. The locking screw 114 is also threadedly engaged with the fine-tuning body 101 to lock the fixed shaft 102, so that the fine-tuning body 101 can no longer rotate.

[0031] In this embodiment, the shaft of the small rubber roller 6 is connected to a drive motor at one end near the wall plate, and the roller is driven to rotate by the motor.

[0032] In this embodiment, the slider 109 and the threaded end of the adjusting screw 112 are connected in a fine-neck screw connection. The threaded end of the adjusting screw 112 has a fine-neck structure, and the head has a small-diameter thread. The diameter of the fine-neck is smaller than the diameter of the small-diameter thread. The fine-neck structure is located between the thread of the adjusting screw 112 and the small-diameter thread on the head. The slider 109 has a corresponding small-diameter threaded through-hole and a large-diameter blind hole coaxial with it. This blind hole can accommodate the small-diameter threaded head of the adjusting screw 112 with a margin. When the adjusting screw 112 rotates and moves longitudinally along its own axis, this connection structure can constrain the small-diameter threaded head of the adjusting screw 112 to always remain within the large-diameter blind hole of the slider 109, thus allowing the slider 109 to move synchronously with the axial movement of the adjusting screw 112, converting the rotational motion of the adjusting screw 112 into the linear movement of the slider 109.

[0033] In this embodiment, the head of the unthreaded end of the adjusting screw 112 is a regular hexagon, and through holes perpendicular to each side of the regular hexagon are provided. A small steel rod can be inserted into the hole to rotate the adjusting screw 112, so as to accurately adjust the glue supply online.

[0034] In this embodiment, the outer surface of the slider 109 is engraved with marking arrows and text that correspond to the changes in the amount of adhesive supplied, indicating the adjustment result corresponding to the fine-tuning direction.

[0035] The online fine-tuning process for glue supply is as follows: A small steel rod is inserted into the small hole on the hexagonal side of the adjusting screw 112. The adjusting screw 112 is rotated to move it axially, thereby causing the slider 109 to move synchronously. Through the connecting rod 108, the rocker arm 107 is rotated. The rotation of the rocker arm 107 forces the eccentric shaft 104 to rotate accordingly. Due to the eccentric structure of the eccentric shaft 104, the needle roller bearing 103 mounted on it is slightly adjusted upward by a displacement, which in turn drives the glue cylinder seat 3 to deflect upward by a small angle on its own axis. The glue cylinder 2 and the large glue roller 5 are slightly offset accordingly, and the gap between the large glue roller 5 and the small glue roller 6 is slightly reduced. The glue amount on the small glue roller 6, i.e., the glue supply, is reduced accordingly. Conversely, Insert a small steel rod into the small hole on the hexagonal side of the adjusting screw 112, and rotate the adjusting screw 112 in the opposite direction to make it move axially in the opposite direction. This causes the slider 109 to move synchronously in the opposite direction. Through the connecting rod 108, the swing arm 107 rotates in the opposite direction. The reverse rotation of the swing arm 107 forces the eccentric shaft 104 to rotate in the opposite direction as well. Due to the eccentric structure of the eccentric shaft 104 itself, the needle roller bearing 103 mounted on it is slightly adjusted downward by a displacement, which in turn drives the glue cylinder seat 3 to deflect downward by a small angle with its own rotation axis. The glue cylinder 2 and the large glue roller 5 then deflect slightly in the opposite direction. The gap between the large glue roller 5 and the small glue roller 6 increases slightly, and the glue amount of the small glue roller 6, i.e., the glue supply, increases accordingly.

[0036] By finely adjusting the rotation angle of the eccentric shaft 104, the deflection angle of the glue cylinder seat 3 is slightly adjusted, thereby finely adjusting the gap between the glue cylinder 2 and the large glue roller 5 assembly and the small glue roller 6. This allows for precise adjustment of the glue application amount, i.e., the glue supply amount, of the small glue roller 6. This ensures accurate adjustment of the glue-carrying amount of the cork paper tape passing around the outer circumference of the small glue roller 6, greatly reducing the difficulty and time required for adjustment, and significantly reducing the number of defective products generated during online adjustment. The entire adjustment process can be completed without stopping the machine, even while it is running online.
