Abstract
Description
Technical Field
[0001] The utility model relates to the field of tobacco production equipment, and particularly relates to a precision adjustment mechanism for novel tobacco pleat cutting production. Background Art
[0002] Traditional tobacco is of the high-temperature combustion type. With the development of the times, the harm of second-hand smoke from traditional tobacco has been increasingly emphasized by people. With the progress of technology, novel tobacco - low-temperature non-combustible cigarettes have emerged in line with the market; this kind of tobacco is of the flue-cured type, does not produce second-hand smoke, does not burn, is fashionable and avant-garde, and causes less harm to the human body. The tobacco leaves of this low-temperature non-combustible novel tobacco are in the form of thin sheet materials (hereinafter referred to as: thin sheets), and the cooling section is made of a PLA material (hereinafter referred to as: PLA).
[0003] From the perspective of production, in order to facilitate the subsequent bundling process, we need to pre-press and cut these flat materials into a state of being seemingly broken but actually connected (thin sheet process requirements) or pleat-cut into strips of uniform specifications (PLA process requirements) according to different actual production situations, which is significantly different from traditional tobacco; therefore, the production method of this novel tobacco has also undergone fundamental changes. Under this market background, an efficient, reliable, precise, and easily adjustable roller gap adjustment mechanism has become an urgent need for novel tobacco manufacturers. Especially after several years of development of low-temperature non-combustible novel tobacco, there has been no major breakthrough in the key production step of pleat cutting production equipment. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a precision adjustment mechanism for pleat cutting production of non-combustible novel tobacco in view of the above-mentioned deficiencies of the prior art, which integrates automation, intelligence, and miniaturization, and greatly improves the production efficiency of the pleat cutting process of novel tobacco.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A novel precision adjustment mechanism for tobacco pleating production comprises a support frame, a passive roller assembly and an active roller assembly mounted in the support frame from top to bottom, and a differential arranged at the rear of the support frame; the active roller assembly is connected to the active input motor arranged at the rear of the support frame through a coupling; the passive roller assembly is connected to the output shaft of the differential, and the differential can make the passive roller assembly and the active roller assembly have the same rotation speed and opposite direction; both ends of the passive roller assembly are provided with passive roller connecting frames, one end of the passive roller connecting frame is hinged to the support frame through a rotating shaft, and the other end of the passive roller connecting frame is mounted on two constant-speed cams of the output shaft through a bridging plate; the output shaft frame is mounted on the support frame, and its rear end is connected to the output shaft of a large-ratio reduction motor arranged at the rear of the support frame, so that the constant-speed cam can lift the passive roller connecting frame to deflect under the drive of the large-ratio reduction motor, thereby realizing precise fine-tuning of the gap between the passive roller assembly and the active roller assembly.
[0007] Preferably, a mounting plate is provided on the support frame above the output shaft; two cylinders are invertedly mounted on the mounting plate, and piston rods of the cylinders pass through the mounting plate and are connected to the upper surface of the strapping plate.
[0008] Compared with the prior art, the beneficial effects of the utility model are:
[0009] The precision adjustment mechanism for pleating production of the utility model utilizes the high-precision control characteristics of the servo motor, and realizes the fine adjustment of the force applied by the large thrust cylinder between the two pleating cutting wheels through the output of the large-proportional reducer and the constant-speed cam. At the same time, the overall structure is compact and small, and the functional layout is clear and reasonable; the adjustment method using the servo motor to increase the proportional reducer is more precise and stepless compared to the previous manual eccentric method; the operation only requires entering some parameters on the screen, which is also more simple, fast and efficient.

[0012] The technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments and drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present utility model.
[0013] likeFigure 1 and 2 As shown, the novel precision adjustment mechanism for tobacco pleating production of this embodiment comprises a support frame 1, a passive roller assembly 4 and an active roller assembly 5 arranged in the support frame from top to bottom, and a differential 3 arranged at the rear of the support frame 1; the active roller assembly 5 is connected to the active input motor 2 arranged at the rear of the support frame 1 through a coupling; the passive roller assembly 4 is connected to the output shaft of the differential, and the differential can make the passive roller assembly 4 and the active roller assembly 5 have the same speed and opposite direction; both ends of the passive roller assembly 4 are provided with passive roller connecting frames 4.2 One end of the passive roller connecting frame 4.2 is hinged to the supporting frame 1 through a rotating shaft 4.1, and the other end of the passive roller connecting frame 4.2 is mounted on two constant-speed cams 6.3 of the output shaft 6.2 through a strap 4.3; the output shaft 6.2 is mounted on the supporting frame 1, and its rear end is connected to the output shaft of a large-ratio reduction motor 6.1 arranged at the rear part of the supporting frame 1, so that the constant-speed cam 6.3 can lift the passive roller connecting frame 4.2 to deflect under the drive of the large-ratio reduction motor 6.1, thereby realizing precise fine-tuning of the gap between the passive roller assembly 4 and the active roller assembly 5.
[0014] In this embodiment, a mounting plate 6.5 is provided on the support frame 1 above the output shaft 6.2; two cylinders 6.4 are invertedly mounted on the mounting plate 6.5, and the piston rods of the cylinders pass through the mounting plate 6.5 and are connected to the upper surface of the strap 4.3.
[0015] Take thin slice shredding as an example: the outer cylindrical surface of the driving wheel on the passive roller assembly 4 is parallel and covered with tooth grooves with an angle of 60° and a pitch of 0.8 (this data is obtained through production practice), and its function is a cutter; the outer cylindrical surface of the roller of the active roller assembly 5 is the same as the outer diameter of the passive roller, but it is smooth, and its function is a cutting board.
[0016] When working, the main power motor 2 outputs speed, so that the speed of the passive roller assembly 4 and the active roller assembly 5 are the same in magnitude and opposite in direction; the piston rod of the large thrust cylinder 6.4 extends and applies force to the passive roller assembly 4, so that the active and passive rollers are in contact and there is a considerable pressure between the two rollers, and the thin sheet material passes through the two moving wheels and is pressed and cut by the active and passive rollers into an effect that seems to be broken but not broken, and is connected by a thread. When it is necessary to adjust the pressure cutting effect to make the shredding effect deeper or shallower, the large-ratio reduction motor 6.1 is a servo motor. The servo motor rotates a certain angle and outputs the rotation displacement to the output shaft 6.2, thereby driving the two constant-speed cams on the output shaft to rotate. The cam forces the passive roller assembly 4 to move up or down slightly, thereby changing the force applied by the thrust cylinder 6.4 between the two moving wheels, thereby changing the depth of the shredding effect.
[0017] The adjustment method of using a servo motor to increase the ratio of the reduction gearbox is more precise and stepless compared to the previous manual eccentric method. When operating, only some parameters need to be input on the screen to achieve it, which is also more simple, fast, and efficient. Similarly, when it is necessary to produce wrinkles in PLA material, only the two rollers need to be replaced with special rollers for wrinkles, and its adjustment method is the same as that of wire cutting.
[0018] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
