Description

Technical Field

[0001] This invention relates to the field of cigarette testing equipment, and in particular to a laboratory cigarette slitting machine. Background Technology

[0002] In the laboratory, in order to further optimize the finished cigarettes through experimental research, it is necessary to cut the cigarettes or filter rods into different lengths according to the length requirements.

[0003] Currently, most cigarette cutting is done on large-scale factory production lines. These lines operate step-by-step, with the cigarette cutter serving as a component, transitioning between processes. It cannot be used independently as a whole for cigarette cutting. Furthermore, because the production processes for cigarettes and filters are completely different, cigarette production lines can only cut the smoking section or the filter section separately. Therefore, in existing technologies, when cutting the smoking section or filter section of a cigarette in the laboratory, the primary method is manual cutting with blades. This method is inefficient, time-consuming, labor-intensive, and suffers from poor precision and inconsistency. Summary of the Invention

Detailed Implementation

[0042] To better explain and facilitate understanding of the present invention, a detailed description of the invention is provided below with reference to the accompanying drawings and specific embodiments. In this document, directional terms such as "upper," "lower," "front," "back," "left," and "right" are used interchangeably. Figure 2 The orientation is used as a reference. Figure 1The position of the base body 1 is defined as "lower"; the position of the frame 22 is defined as "rear"; and the position of the loading body 3 is defined as "left".

[0043] See Figures 1-2 As shown, a laboratory cigarette slicing machine includes a base body 1, a cutting body 2, and a feeding body 3.

[0044] In this embodiment, the feeding body 3 is disposed on the top of the cutting body 2 and connected to the cutting body 2, and the feeding body 3 can feed materials onto the cutting body 2.

[0045] It should be noted that the material here can refer to either the smoke-generating section of the cigarette or the filter rod section. It can be appropriately replaced according to actual needs. This provides greater applicability and facilitates further research into optimizing experimental formulations and developing production-related processes and parameters.

[0046] See Figure 2 As shown, the cutting body 2 is mounted on the base body 1. The cutting body 2 includes a cutting drum 21 that can rotate relative to the base body 1, a frame 22 mounted on one side of the cutting drum 21, a drive unit 23 mounted on the frame 22, and a cutter assembly 24. The drive unit 23 can drive the cutting drum 23 to rotate.

[0047] Furthermore, the cutting drum 21 includes a front section 211 and a rear section 212 spaced apart, with the gap between them used to accommodate part of the cutting blade assembly 24. In this embodiment, the cutting drum 21 is configured as two sections arranged front and rear, with a gap between them to accommodate the cutting disc 244 of the cutting blade assembly. This results in a compact spatial structure and enables simultaneous sorting and cutting, performing cutting operations while positioning the material, thus accelerating cutting efficiency and improving cutting accuracy. Moreover, the cutting drum 21 has multiple grooves 25 spaced along its circumference for receiving material, with the direction of the grooves 25 parallel to the axial direction of the cutting drum 21. The grooves 25 facilitate the placement and sorting of material. It should be noted that, to accommodate cigarettes of different diameters, the opening of the grooves 25 needs to be relatively large to accommodate various cigarette models. Meanwhile, to prevent small cigarette sticks from loosening in the groove 25, a first clamping assembly 4 and a second clamping assembly 5 are fitted on both the front section 211 and the rear section 212 of the cutting drum. These components prevent material from tipping over and secure the material to facilitate cutting by the cutter assembly 24. Additionally, a frame 22 is positioned at one end of the cutting drum 21, and the cutter assembly 24 is mounted on the frame 22 to cut the material. By positioning the frame 22 on the rear side of the upper end face of the base body 1, one function is to support the cutter assembly 24 and drive the cutting drum 21 to rotate in coordination with the drive unit 23 of the cutter assembly 24. Another function is to seal the rear section 212 of the cutting drum from the rear side; correspondingly, a sealing plate is provided on the front end face of the front section 211 of the cutting drum.

[0048] In this embodiment, a laboratory cigarette slicing machine is provided, which uses a separate slicing machine for slicing cigarettes or filter rods, and this slicing machine is only used in the laboratory for further cutting of tobacco. The slicing machine of this invention uses a separate cutting blade assembly on the frame to cut the cigarettes or filter rods to be cut from the feeding body. Compared with manual cutting, the cutting efficiency is higher and the cutting is more precise.

[0049] Furthermore, the first clamping assembly 4 and the second clamping assembly 5 can be displaced along the axial direction of the cutting body 2 to abut against both ends of the material placed in the groove 25, thereby positioning the material. The material can be clamped and fixed from both end faces by the first clamping assembly 4 and the second clamping assembly 5.

[0050] Furthermore, the first clamping assembly 4 includes an annular baffle 41 fitted onto the outer peripheral wall of the front section 211 of the cutting drum, a ball screw 42 passing through the axial direction of the annular baffle 41, and an adjusting drive 43 that drives the ball screw 42 to rotate. The adjusting drive 43 is a micro motor. The adjusting drive 43 is located on the side of the cutting body 2 away from the frame 22. This adjusting drive 43 is located at one end of the sealing plate and can control the sliding of the annular baffle 41 back and forth in the front section 211 of the cutting drum by forward and reverse rotation. Moreover, the adjusting drive 43 is connected to the screw of the ball screw 42 and can drive the screw to rotate. The nut of the ball screw 42 is connected to the annular baffle 41. The rotation of the screw drives the nut to reciprocate linearly along the axial direction of the screw, thereby driving the annular baffle 41 to move axially along the front section 211 of the cutting drum. The electric adjustment method is more precise and less labor-intensive.

[0051] It should also be noted that, in addition to the ball screw 42, multiple guide rods are also provided along the axial direction of the cutting drum 21, and the guide rods can more accurately ensure the axial movement position of the annular baffle 42.

[0052] Furthermore, the first clamping assembly 4 also includes a feeding baffle 44 integrally formed with the annular baffle 41, and the feeding baffle 44 extends along the length direction of the feeding body 3. The second clamping assembly 5 has the same structure as the first clamping assembly 4. The integrally formed upper baffle 44 facilitates adjustment and operation, allowing adjustment of the upper baffle 44 while adjusting the annular baffle 41. The upper baffle 44 also guides the material during feeding of the feeding body 3.

[0053] Further, see Figure 3 As shown, the feeding body 3 includes an inclined guide plate 31 and a vertically downward mounting plate 32. The mounting plate 32 is detachably connected to both ends of the cutting drum 21. The bottom of the guide plate 31 has an inclined outlet that communicates with the groove 25, and feeding baffles 44 are respectively arranged on both sides of the guide plate 31. This design can increase the feeding capacity at one time, and the inclined setting is more conducive to the falling of materials. The detachable connection of the mounting plate 32 to the cutting drum 21 facilitates maintenance and replacement of the feeding body 3.

[0054] See Figure 4 As shown, in this embodiment, the feeding body 3 also includes a mounting cover 33 that is fastened to the guide plate 31 and has one side wall parallel to the guide plate 31. A support chamber is formed between the inner side wall of the mounting cover 33 and the guide plate 31, and an auxiliary support mechanism 6 is provided in the support chamber on one side of the mounting cover 33.

[0055] It should be noted that the auxiliary support mechanism 6 can better support the material on the feeding body 3, preventing the material from scattering due to excessive tilting. Moreover, applying moderate pressure from the side perpendicular to the material laid flat on the guide plate 31 can prevent tipping while also speeding up the feeding speed.

[0056] See Figure 5 As shown, the auxiliary support mechanism 6 includes an adjusting rod 61 perpendicular to the guide plate 31 and passing through the mounting cover 33, and an adjusting plate 62 located at one end of the adjusting rod 61. Multiple rollers 63 are provided on the side wall of the adjusting plate 62 away from the adjusting rod 61, and the axes of the rollers 63 are parallel to the axis of the cutting drum 21. A spring 64 is fitted onto the adjusting rod 61, with one end of the spring 64 abutting against the adjusting plate 62 and the other end abutting against the inner wall of the mounting cover 33. An adjusting nut 65 is screwed onto the portion of the adjusting rod 61 extending out of the mounting cover 33. The adjusting nut 65 can be adjusted appropriately according to the width of the material in the direction perpendicular to the thickness of the guide plate 31, so that the rollers 63 on the adjusting plate 62 just abut against the contact surface formed by the material. It should also be noted that adding multiple rollers 63, which are in contact with each other, and rotating as the material falls, allows the rollers 63 to provide an auxiliary acceleration effect for other materials.

[0057] It should also be noted that if material gets stuck on the guide plate 62, the rotating wheel 66 can be manually rotated from the outside of the mounting cover 33. The rotating wheel 66 is connected to one end of any of the rollers 63. That is, when material gets stuck, rotating the rotating wheel 66 will drive the roller 63 to rotate outwards towards its contact surface, thereby moving the material contact surface and preventing it from getting stuck.

[0058] Furthermore, the cutting assembly 24 includes a cutting motor 241 mounted on the frame 22, a transmission mechanism 242 connected to the output end of the cutting motor 241, a rotating shaft 243 connected to the transmission mechanism 242, and a cutter head 244 connected to the rotating shaft 243. The cutting assembly 24 has a simple structure, facilitating cutting. The cutting motor 241 can drive the rotating shaft 243 to rotate via the transmission mechanism 242, thereby causing the cutter head 244 to rotate within the gap. The cutting motor 241 is directly mounted on the frame 22, and the frame 22 has a large front-to-back width, which effectively prevents axial deformation.

[0059] When the cutting drum 21 rotates, the cutter head 244 can cut the material in the groove 25 of the cutting drum 21.

[0060] Furthermore, it also includes a material collection body 7. The material collection body 7 is located on top of the base body 1 and below the cutting drum 21, and is used to receive the cut material. The collection of material facilitates the optimization of new tobacco formulations and the development of production-related processes and parameters.

[0061] Furthermore, the inner cavity of the base body 1 is provided with electrical control components, which are electrically connected to the drive component 23, the cutting motor 241, the adjustment drive component 43, and the adjustment drive component 43 of the second clamping assembly 5. The electrical control structures are all existing control systems, and will not be described in detail here.

[0062] Furthermore, a dust cover 8 is provided on the upper part of the base body 1 to ensure the cleanliness of the cigarettes after cutting.

[0063] In this embodiment, compared to existing assembly line processing, an integrated and optimized laboratory-specific slitting machine is used. Furthermore, unlike existing machines, this embodiment is miniaturized and integrated, resulting in a more compact structure and more comprehensive functions. This significantly improves the slitting effect and quality in the laboratory.
