Description

Technical Field

[0001] This application relates to the field of tobacco processing equipment technology, specifically a cigarette cutting support device. Background Technology

[0002] In the cigarette production process, a large number of substandard cigarettes (waste cigarettes) that do not meet process standards are inevitably generated. Although the cigarettes themselves are substandard, the tobacco they contain still has high recycling value. Currently, the industry commonly uses equipment such as air blowing, rod beating, or cutting methods to process waste cigarettes to separate and recover the tobacco. To improve the whole tobacco recovery rate, a new waste cigarette processing technology combining pneumatic conveying and rotary blade center cutting has been proposed and applied. In this technology, to ensure that the rotary blade can accurately and stably cut the waste cigarettes in the pneumatic conveying process, a special support base needs to be designed to fix the radial position of the cigarettes. However, existing technologies generally use an integrated tubular support base.

[0003] This integrated support has significant drawbacks in practical applications: because the waste cigarettes are transported at high speed using a pneumatic method, and the friction between the rotating blade and the cigarettes is relatively small, the residual high-pressure gas in the support cavity is released instantly upon completion of the cutting process. This release violently blows out the cut cigarette fragments, tobacco shreds, and auxiliary materials (such as filter rods and cigarette paper). This sudden release of high-pressure gas not only causes the materials to travel too far, making them difficult to collect, but more importantly, it causes severe breakage of the tobacco shreds (i.e., "fragmentation"), significantly reducing the whole tobacco shred rate and reuse value.

[0004] Therefore, this application proposes a split-type waste tobacco cutting support, which can alleviate the impact of high-pressure gas during cutting, thereby significantly reducing tobacco breakage and improving the quality and whole tobacco yield of recycled tobacco. Utility Model Content

[0005] The main purpose of this application is to provide a tobacco cutting support device, which aims to solve the technical problem in the prior art that the tobacco shreds are severely broken due to the sudden release of high-pressure gas at the moment of cutting.

[0006] To achieve the above objectives, this application provides the following technical solution: A cigarette cutting support device, comprising: The left and right clamping blocks are positioned opposite each other, and both sides of the blocks that are close to each other are provided with a sliding groove and a step. When the left clamping block and the right clamping block are joined together on their sides, the two grooves together form a cigarette channel, and the two steps form a through-cut slit in the radial direction of the cigarette channel; the outer walls of the left clamping block and the right clamping block at the ends of the cut slit are provided with pressure relief holes that communicate with the cigarette channel. A connecting component is used to securely connect the left clamping block and the right clamping block and maintain their assembled state.

[0007] As a further improvement of this application, the cigarette channel includes a cutting section, a transition section and a positioning section connected sequentially along the axial direction. The cutting section is close to the cutting seam and is a circular hole that is interference-fitted with the outer diameter of the cigarette, with a length equal to the extension length of the cutting seam. The transition section is a frustum hole with a radius matching the cutting section and the positioning section respectively. The positioning section is far from the cutting seam and is a circular hole with a radius greater than 1.2 to 1.5 times that of the cutting section.

[0008] As a further improvement of this application, the outer walls of the left and right clamping blocks of the cutting seam are provided with guide slopes that are inclined toward the axis of the cigarette channel; there are multiple pressure relief holes, which are distributed along the slope direction of the guide slopes and are connected to the cutting end of the cigarette channel.

[0009] As a further improvement of this application, the connecting assembly includes at least two parallel locating pins and at least one bolt. The mating surfaces of the left clamping block and the right clamping block are provided with locating holes that are interference-fitted with the locating pins. The thread of each bolt passes through the through hole of the left clamping block and the threaded hole of the right clamping block in sequence, thereby locking and fixing the two together.

[0010] The technical solution provided in this application may include the following beneficial effects: During use, this application employs a split left and right clamping block assembly structure, with a pressure relief hole on the outer wall of the cutting end that communicates with the cigarette channel. This effectively mitigates the impact of high-pressure gas within the support cavity during the instantaneous cutting of the cigarette by the rotating blade. When the cigarette is cut open, the residual high-pressure gas can be rapidly and gently released to both sides through the symmetrically distributed pressure relief holes, significantly reducing the violent blowing effect of gas on the cut cigarette fragments and internal tobacco. This not only greatly reduces the breakage of tobacco due to high-speed scattering and collision ("fragmentation"), improving the whole tobacco yield and reuse value, but also avoids disorderly splashing of materials, facilitating subsequent centralized collection, and overall improving the efficiency of waste cigarette processing and the quality of resource recovery.

[0013] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are merely some, not all, of the embodiments of this application. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0014] Figure 1 An embodiment of a cigarette cutting support device according to this application is shown; see [link to relevant documentation]. Figure 1 In this embodiment, the cigarette cutting support device includes: a left clamping block 1 and a right clamping block 2 arranged opposite to each other, and a connecting component 3 that fixes the left clamping block 1 and the right clamping block 2 together and keeps them in a spliced ​​state.

[0015] Among them, see Figure 1 Both the left clamping block 1 and the right clamping block 2 have grooves and a single step on their adjacent sides. When the adjacent sides of the left clamping block 1 and the right clamping block 2 are joined together, the two grooves together form a cigarette channel 4, and the two steps form a through-cutting slit 5 in the radial direction of the cigarette channel 4. The outer walls of the left clamping block 1 and the right clamping block 2 at the ends of the cutting slit 5 are provided with pressure relief holes 6 that communicate with the cigarette channel 4. The pressure relief holes 6 can effectively alleviate the impact of high-pressure gas in the support cavity at the moment the rotating blade completes the cutting of the cigarette. When the cigarette is cut open, the residual high-pressure gas can be quickly and gently released to both sides through the symmetrically distributed pressure relief holes 6, which significantly reduces the violent blowing effect of gas on the cut cigarette fragments and internal tobacco. This not only greatly reduces the breakage of tobacco caused by high-speed scattering and collision ("fragmentation"), but also improves the whole tobacco rate and reuse value of the recycled tobacco, while avoiding disorderly splashing of materials, which is conducive to subsequent centralized collection, thus improving the overall efficiency of waste cigarette processing and the quality of resource recycling.

[0016] Further, see Figure 1The cigarette channel 4 includes a cutting section 41, a transition section 42, and a positioning section 43 connected sequentially along the axial direction. The cutting section 41 is close to the cutting slit 5 and is a circular hole that interferes with the outer diameter of the cigarette, with a length equal to the extension length of the cutting slit 5. The transition section is a frustum-shaped hole with a radius matching that of the cutting section 41 and the positioning section respectively. The positioning section is far from the cutting slit 5 and is a circular hole with a radius greater than that of the cutting section 41 by 1.2 to 1.5 times. The cutting section 41 provides a stable radial constraint on the cutting area of ​​the cigarette, ensuring cutting accuracy. At the same time, the positioning section 43 provides a larger accommodating space for the cigarette, effectively preventing deformation or jamming of the cigarette due to excessive constraint during transportation or positioning, thus ensuring smooth cigarette transportation and positioning.

[0017] Further, see Figure 1 The outer walls of the left clamping block 1 and right clamping block 2 of the cutting seam 5 are both provided with guide slopes 7 inclined towards the axis of the tobacco channel 4. Multiple pressure relief holes 6 are distributed along the slope direction of the guide slopes and are connected to the cutting end of the tobacco channel 4. The guide slopes 7 avoid affecting the cutting blade while forcing the gas to be ejected axially into the channel, effectively preventing the gas from being ejected erratically in all directions. The multiple pressure relief holes 6 distributed along the slope achieve staged pressure relief, significantly weakening the impact force of instantaneous release, thus more effectively protecting the tobacco structure and further reducing the risk of breakage.

[0018] Further, see Figure 2 The connecting component 3 includes at least two parallel positioning pins 31 and at least one bolt 32. The mating surfaces of the left clamping block 1 and the right clamping block 2 are provided with positioning holes 33 that are interference-fitted with the positioning pins 31. The thread of each bolt 32 passes through the through hole 34 of the left clamping block 1 and the threaded hole 35 of the right clamping block 2 in sequence, locking the two together. By adopting the combination connection method of positioning pins 31 and bolts 32, it is ensured that the left and right clamping blocks 2 can always be accurately reset and firmly assembled during repeated disassembly and assembly, effectively maintaining the geometric accuracy and stability of the cigarette channel 4 (especially the key cutting section 41), thereby ensuring the consistency and reliability of the cigarette cutting operation, and facilitating the maintenance of the device and the replacement of parts.

[0019] For example, the working principle of a cigarette cutting support device is as follows: See Figure 3When waste cigarettes are fed into the device at high speed by the pneumatic conveying system, the left clamp 1 and the right clamp 2 are locked together by the connecting component 3. The sliding grooves on their sides together form a through cigarette channel 4, and the cigarette is constrained to move axially within this channel. During the cutting process, the rotating blade is radially inserted into the cutting slit 5 formed by the steps of the left and right clamps 2, performing a centering cut on the cigarette. At the moment the cutting is completed, the high-pressure gas in the support cavity loses its sealing barrier due to the separation of the cigarette. At this time, the high-pressure airflow is rapidly released to both sides through the pressure relief holes 6 (symmetrically distributed on the left and right sides) on the outer wall of the end where the cutting slit 5 is located. This symmetrical pressure relief design disperses and attenuates the gas impact force, avoiding the scattering of cigarette fragments and tobacco shreds caused by the violent ejection of gas along the axial direction of the channel in the integrated support seat. Finally, the tobacco shreds fall smoothly under the controlled and slow-released airflow, significantly reducing collision and breakage, and ensuring the integrity rate and collection efficiency of the recycled tobacco shreds.

[0020] In this embodiment, the coordinated design of the split left / right clamping block 2, the stepped cutting seam 5, and the pressure relief hole 6 on the outer wall effectively solves the problem of tobacco breakage caused by the disorderly release of high-pressure gas during the cutting process in traditional integrated support bases. The symmetrical pressure relief hole 6 allows the gas to flow smoothly to both sides, significantly weakening the impact force, reducing tobacco breakage, and improving the whole tobacco yield. Furthermore, the three-section tobacco channel 4 provides interference constraint on the cutting area and loose accommodation in the positioning area, ensuring cutting accuracy while preventing tobacco jamming. The guide slope 7 and the graded pressure relief hole 6 optimize the axial gas release path, further suppressing airflow turbulence. The combination of positioning pin 31 and bolt 32 ensures the geometric accuracy and operational stability of the device after repeated disassembly and assembly. Ultimately, this achieves efficient and low-loss recycling of tobacco during the cutting process of waste tobacco, significantly improving resource reuse value and equipment reliability.

[0021] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
