Description

Technical Field

[0001] This utility model relates to the field of cigarette cutting technology, specifically to a high-speed pneumatic cigarette cutting device. Background Technology

[0002] In the current common model for recycling and processing waste cigarettes, cutting the cigarette paper to separate the tobacco from non-tobacco materials such as the cigarette paper and filter rod is the most effective method with the highest tobacco recovery rate. This method results in a high tobacco recovery rate, increases the proportion of whole tobacco strands, and enables timely recycling, avoiding the downgrading of tobacco. However, due to the physical characteristics of cigarettes, ordinary cutting methods can only cut on one side with a relatively deep cut, or may leave small paper scraps after cutting, which can affect the whole tobacco strand rate and recycling efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a high-speed pneumatic slicing device for cigarettes, which addresses the aforementioned problems by allowing for rapid manual adjustment of the cutting depth according to the cigarette specifications. This enables high-speed, counter-directional slicing of cigarettes, quickly separating tobacco from non-tobacco substances and reducing paper scraps and impurities in the tobacco.

[0004] The technical solution of this utility model is as follows:

[0005] A high-speed pneumatic cigarette slicing device includes a pneumatic cigarette launching mechanism, the cigarette launching port of which is connected to the inlet of a cigarette guiding mechanism; two cutting mechanisms are provided at the outlet of the cigarette guiding mechanism; the two cutting mechanisms are symmetrically arranged, and the center line of symmetry of the two cutting mechanisms is collinear with the center line of the cigarette guiding mechanism and the pneumatic cigarette launching mechanism; after compressed gas is introduced into the pneumatic cigarette launching mechanism, a cigarette is drawn in at the inlet end and ejected at high speed from the launching port; the cutting mechanisms rotate at high speed in the opposite direction to the movement direction of the cigarette; the cutting mechanisms slice the cigarette.

[0006] Furthermore, the cutting mechanism includes a motor, an eccentric gear, and an alloy blade; the motor is fixedly connected to the eccentric gear and rotatably connected to the alloy blade, and the motor provides power for the rotation of the alloy blade.

[0007] Furthermore, the eccentric gears of the two cutting mechanisms mesh with each other, and the eccentric gear of one of the cutting mechanisms is also meshed with an adjusting gear. By rotating the adjusting gear, the eccentric gear is driven to rotate, thereby adjusting the center distance between the two alloy blades.

[0008] With the above structure, a set of symmetrically arranged cutters can adjust the cutting depth by adjusting the combination of eccentric gears. Each gear can be rotated to adjust the cutting depth by 0.1mm, and the cutting depth can be adjusted according to the actual situation, making it widely applicable.

[0009] Furthermore, the alloy blade is pressed onto the cutter shaft by a blade cap, and the cutter shaft is connected to the shaft drive of the motor.

[0010] Furthermore, the cigarette guiding mechanism includes a cigarette guiding support, the inlet end opening of which is connected to the outlet end opening of the cigarette pneumatic launching mechanism; a cigarette guide is connected to the cigarette guiding support by screws.

[0011] Furthermore, the cigarette guide includes a lower guide and an upper guide, which are arranged in the extension direction of the inlet end of the cigarette guide support.

[0012] Through the above structure, the cigarette guide mechanism ensures the state and position of the cigarette during cutting, avoiding situations where it is not cut or is cut unevenly from left to right. This function is especially important for cigarettes with special filter rods.

[0013] Furthermore, the pneumatic cigarette launching mechanism includes a chamber flange, a chamber flange cover, and a positive pressure air inlet pipe connector; the chamber flange is connected to the chamber flange cover by screws, and a cavity is formed between the chamber flange and the chamber flange cover; the positive pressure air inlet pipe connector is disposed on the chamber flange.

[0014] Furthermore, compressed air is introduced into the positive pressure air inlet pipe joint to form a venturi effect, creating a negative pressure suction near the inlet end of the cigarette pneumatic launch mechanism. The compressed air is emitted from the pipe of the air chamber flange cover, while simultaneously drawing in the cigarette at the inlet and then ejecting it at high speed through the outlet.

[0015] With the above structure, the pneumatic cigarette launching mechanism is suitable for conventional cigarettes of different specifications and double-length cigarettes. The strength of the negative pressure suction of the pneumatic device can also be adjusted by adjusting the positive pressure. It is suitable for handling cigarettes under different conditions during the waste smoke treatment process.

[0016] Furthermore, the pneumatic cigarette launching mechanism is fixedly supported on the mounting base plate by a pneumatic launching mechanism support seat, the cigarette guiding mechanism is arranged on the mounting base plate by screws and pins, and the symmetrically arranged cutting mechanism is also arranged on the mounting base plate.

[0017] Furthermore, both the eccentric gear and the adjusting gear are disposed on the lower surface of the mounting base plate.

[0018] Compared with existing technologies, the beneficial effects of this utility model are:

[0019] The device in this application mainly includes a cigarette guiding mechanism and a cutting mechanism. The cigarette pneumatic launching mechanism is connected to the cigarette guiding mechanism at its outlet end. A set of cutters is symmetrically arranged at the end of the guide nozzle in a direction perpendicular to the direction of cigarette movement. The high-speed moving cigarette is cut into two halves by the action of the high-speed rotating cutters, thus realizing the pneumatic cutting of the cigarette. Attached Figure Description

Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0027] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0028] Please see Figure 1-5 A high-speed pneumatic cutting device for cigarettes, such as Figure 1As shown, the device includes a pneumatic cigarette launching mechanism 1, the cigarette launching port of which is connected to the inlet of a cigarette guiding mechanism 3; two cutting mechanisms 5 are provided at the outlet of the cigarette guiding mechanism 3; the two cutting mechanisms 5 are symmetrically arranged, and the center line of symmetry of the two cutting mechanisms 5 is collinear with the center line of the cigarette guiding mechanism 3 and the pneumatic cigarette launching mechanism 1; after compressed gas is introduced into the pneumatic cigarette launching mechanism 1, a cigarette is drawn in at the inlet end and ejected at high speed from the launching port; the cutting mechanisms 5 rotate at high speed in the opposite direction to the movement direction of the cigarette; the cutting mechanisms 5 cut the cigarette.

[0029] like Figure 4 As shown, the cutting mechanism 5 includes a motor 51, an eccentric gear 52, and an alloy blade 53; the motor 51 is fixedly connected to the eccentric gear 52, and the motor 51 is rotatably connected to the alloy blade 53, providing power for the rotation of the alloy blade 53. Figure 5 As shown, the eccentric gears 52 of the two cutting mechanisms 5 mesh with each other, and one of the eccentric gears 52 of the cutting mechanism 5 also meshes with an adjusting gear 54. By rotating the adjusting gear 54, the eccentric gear 52 is driven to rotate, thereby adjusting the center distance between the two alloy blades 53. In order to adjust the distance of the cutting mechanism, it is possible to cut cigarettes of different thicknesses, making it more versatile. The alloy blades 53 are pressed onto the cutter shaft 56 by the blade cover 55, and the cutter shaft 56 is connected to the shaft drive of the motor 51. The cigarette is cut by the symmetrically arranged high-speed rotating cutting mechanism. The cutting can cut the cigarette without damaging the tobacco, reducing the generation of impurities in the tobacco.

[0030] like Figure 3 As shown, the cigarette guiding mechanism 3 includes a cigarette guiding support 31, the inlet end opening of which is connected to the outlet end opening of the cigarette pneumatic launching mechanism 1; a cigarette guide is connected to the cigarette guiding support 31 by screws. The cigarette guide can ensure the stability of the cigarette's state and cutting position during cutting, achieving a better cutting effect.

[0031] The cigarette guide includes a lower guide 32 and an upper guide 33, which are positioned along the extension direction of the inlet end of the cigarette guide support 31. This ensures the stability of the cigarette's position and state during cutting, guaranteeing accurate cutting at the correct location and with a stable and controllable cutting depth. This is particularly important for cigarettes with special filter rods.

[0032] like Figure 2As shown, the pneumatic cigarette launching mechanism 1 includes a chamber flange 11, a chamber flange cover 12, and a positive pressure air inlet pipe connector 13. The chamber flange 11 is connected to the chamber flange cover 12 by screws, and a cavity is formed between the chamber flange 11 and the chamber flange cover 12. The positive pressure air inlet pipe connector 13 is disposed on the chamber flange 11. Compressed air is introduced into the positive pressure air inlet pipe connector 13 and enters the cavity to form a Venturi effect, creating a negative pressure suction near the inlet end of the pneumatic cigarette launching mechanism 1. The compressed air is emitted out through the pipe of the chamber flange cover 12, while simultaneously drawing in the cigarette at the inlet and then ejecting it at high speed through the outlet.

[0033] The pneumatic cigarette launching mechanism 1 is fixedly supported on the mounting base 4 by the pneumatic launching mechanism support 2. The cigarette guiding mechanism 3 is arranged on the mounting base 4 by screws and pins. The symmetrically arranged cutting mechanism 5 is also set on the mounting base 4. The eccentric gear 52 and the adjusting gear 54 are both set on the lower surface of the mounting base 4.

[0034] Working principle:

[0035] The development principle of the pneumatic cigarette launching mechanism is based on Bernoulli's principle in fluid mechanics. It draws on the principle of using a Venturi tube to design the pneumatic cigarette launching device. According to the Venturi effect, low pressure can be generated near a high-speed flowing fluid, thereby creating an adsorption effect. Therefore, negative pressure suction at the inlet automatically draws in the cigarette, and positive pressure blowing at the outlet provides power to the cigarette, ejecting it at high speed. This pneumatic cigarette launching mechanism not only accelerates the cigarette, but also keeps the cigarette in a certain state and ejects it in a straight line, which is more conducive to the subsequent cutting of the cigarette.

[0036] The embodiments described above merely illustrate specific implementation methods of this application, and while the descriptions are detailed and specific, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the technical solution of this application, and these modifications and improvements all fall within the scope of protection of this application.
