Description

Technical Field

[0001] This utility model belongs to the technical field of cigarette production equipment, specifically relating to a cigarette frame for a vacuum rehumidifier. Background Technology

[0002] In the tobacco processing industry, tobacco leaves often stick together at the bottom of the cigarette frames in the vacuum rehumidifier, requiring regular cleaning by operators. Because the tobacco leaves adhere very strongly, ordinary cleaning tools are ineffective, necessitating the use of specialized tools. Each cleaning session takes approximately 10 minutes. During this process, the anti-sticking mesh inside the cigarette frames is easily damaged, which not only impacts the production process but also increases labor costs and spare parts replacement costs.

[0003] An existing vacuum rehumidifier tobacco frame (publication number: CN 220326794 U) discloses a technique that uses polytetrafluoroethylene (PTFE) as the inner frame material, utilizing the non-stick properties of PTFE to reduce tobacco sticking to the inner frame. However, the flat bottom of this tobacco frame still presents the possibility of tobacco sticking; furthermore, this flat bottom design creates some obstruction, affecting the efficiency of vacuuming and making it difficult for steam to fully penetrate the tobacco leaves, thus preventing the tobacco pack from thoroughly rehumidifying and loosening. Therefore, it is necessary to improve the tobacco frame for a vacuum rehumidifier. Utility Model Content

[0004] The purpose of this invention is to provide a tobacco frame for a vacuum rehumidifier, which allows for an appropriate gap between the tobacco pack and the inner frame, facilitating rapid vacuuming, promoting the rapid entry and diffusion of steam, thereby quickly increasing temperature and humidity, effectively rehumidifying and loosening the tobacco leaves; at the same time, the anti-sticking structure can reduce or even eliminate the sticking of tobacco shreds to the inner frame, thus solving the problems mentioned in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A smoke frame for a vacuum dehumidifier includes a smoke frame body with an open top, and through holes on both the side and bottom walls of the smoke frame body. The smoke frame body includes an inner frame, and an anti-sticking structure is provided inside the inner frame. The anti-sticking structure includes support strips and blocking strips. The support strips are disposed on the bottom wall of the inner frame, and the blocking strips are disposed around the inner side walls of the inner frame. When the smoke frame body is loaded with smoke packs, the support strips and the blocking strips are used to separate the smoke packs from the inner walls of the inner frame.

[0007] In this application, the support strips in the anti-sticking structure ensure a gap between the tobacco bale (or stack) and the bottom wall of the tobacco frame. This design facilitates vacuuming, humidification, and heating, preventing tobacco leaves from sticking together and clumping under pressure. Furthermore, the through-holes allow for rapid vacuuming, promoting the rapid entry and diffusion of steam, thereby quickly increasing the temperature and humidity of the vacuum rehumidification process, effectively rehumidifying and loosening the tobacco leaves. Simultaneously, the blocking strips maintain an appropriate distance between the stack and the inner wall of the tobacco frame, preventing tobacco leaves from sticking to the inner wall, optimizing production efficiency and product quality, and reducing energy waste.

[0008] Furthermore, the anti-sticking structure also includes a protective frame, which at least includes an integrally formed connecting frame and a retaining strip. The connecting frame fits into the top opening of the cigarette pack body, and the retaining strip extends into the inner frame and is fitted onto the blocking strip. With this design, the protective frame is the primary contact point with the cigarette pack. Therefore, when cleaning is required, the protective frame can be removed and cleaned separately. This avoids damage to the anti-sticking surface inside the cigarette pack body during cleaning, and at least reduces the frequency of cleaning the cigarette pack body, thereby lowering labor costs and spare parts replacement costs.

[0009] Furthermore, the bottom end of the locking strip is fixedly connected to the support strip. This allows for the complete disassembly of the protective frame and support strip in a single step; similarly, installation is also more convenient.

[0010] Furthermore, the support bar includes vertical and horizontal bars that are integrally and symmetrically arranged.

[0011] Furthermore, the support strip is a support shell with a cavity. The top of the support shell has a V-shaped groove, and the top wall of the V-shaped groove has an air hole communicating with the cavity. The bottom wall of the V-shaped groove has a connecting notch, which connects the cavity to a through hole on the bottom wall of the cigarette frame body. This design allows the air hole to compensate for the impact of the support strip on the performance of the through hole, improving vacuuming efficiency and quality.

[0012] Furthermore, ventilation support shells are connected to both sides of the support shell, and the structure of the ventilation support shells is the same as that of the support shell.

[0013] Furthermore, the cigarette frame body also includes an outer frame, and the inner frame is fixedly installed inside the outer frame. The outer frame is fixed to the outer layer of the inner frame to improve the structural strength of the cigarette frame body, enabling it to have sufficient load-bearing capacity.

[0014] Furthermore, the anti-adhesion structure also includes a first rounded corner and a second rounded corner. Adjacent wall panels of the inner frame are connected by the first rounded corner, and adjacent three wall panels of the inner frame are connected by the second rounded corner. This configuration, by using the first and second rounded corners as transitions at the intersections of the wall panels, achieves a good anti-adhesion effect.

[0015] The utility model adopting the above technical solution has the following advantages:

[0016] In this application, the tobacco pack is lifted and blocked by the support bars and blocking bars, so that there is enough space between the tobacco pack and the bottom and side walls of the inner frame; this can prevent the tobacco leaves from sticking to the inner frame wall; and the through holes provided help to quickly draw a vacuum, promote the rapid entry and diffusion of steam, thereby rapidly increasing the temperature and humidity, effectively rehydrating and loosening the tobacco leaves.

[0017] In this application, the protective frame clamps the blocking strip. When it is necessary to clean the sticky tobacco leaves, the protective frame can be removed separately for cleaning, thereby reducing the frequency of cleaning the tobacco frame body, protecting the tobacco frame body, and extending the service life of the tobacco frame body. When the protective frame is fixedly connected to the support strip, the support strip can also be removed simultaneously, further improving the convenience of cleaning. Attached Figure Description

Detailed Implementation

[0026] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. Furthermore, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0027] like Figures 1 to 5 As shown, in one embodiment, a tobacco frame for a vacuum rehumidifier includes a frame body 1 with an open top. Through holes 4 are provided on the side and bottom walls of the frame body 1. The frame body 1 includes an inner frame 2, within which an anti-sticking structure is provided. The anti-sticking structure includes support strips 6 and blocking strips 5. The support strips 6 are disposed on the bottom wall of the inner frame, and the blocking strips 5 are disposed around the inner side walls of the inner frame. The support strips 6 include integrally symmetrical vertical and horizontal strips. When the frame body 1 is loaded with tobacco packs, the support strips 6 and blocking strips 5 separate the tobacco packs from the inner wall of the inner frame 2. This arrangement, with the support strips 6 providing sufficient space between the tobacco packs and the inner frame, facilitates vacuuming, humidification, and heating, and prevents the tobacco leaves from sticking together and clumping due to pressure. The through holes 4 are densely arranged in an array. During vacuum rehumidification in the vacuum rehumidifier, water vapor can directly enter the inner frame 2 through the through holes 4 and act on the tobacco leaves. Throughout the process, rapid vacuuming can be achieved, promoting the rapid entry and diffusion of steam, thereby quickly increasing the temperature and humidity of the vacuum rehumidification process, effectively rehumidifying and loosening the tobacco leaves. At the same time, the blocking strips 5 can maintain an appropriate distance between the tobacco bale and the inner wall of the tobacco frame body 1, avoiding the adhesion of the tobacco leaves to the inner wall, optimizing production efficiency and product quality, and reducing energy waste.

[0028] In this embodiment, the inner frame 2 is fixedly installed on the outer frame 3 using a full welding process via hot melt welding. The inner frame 2 is made of polytetrafluoroethylene (PTFE). PTFE has the lowest surface tension among solid materials and does not easily adhere to any substance. This embodiment effectively utilizes the non-stick properties of PTFE to reduce the amount of tobacco sticking to the inner frame 2. The outer frame 3 can be made of stainless steel, and reinforcing ribs 31 are fixedly installed on the outer frame 3 using a full welding process to improve the structural strength of the tobacco frame body 1, ensuring sufficient load-bearing capacity. The four corners of the outer frame 3 can be set as square corners 32 as needed to facilitate neatness when empty or stacked.

[0029] In this embodiment, the anti-adhesion structure also includes a protective frame, which comprises an integrally formed connecting frame 7 and a retaining strip 8. The connecting frame 7 fits into the top opening of the cigarette frame body 1, and the retaining strip 8 extends into the inner frame 2 and is fitted onto the blocking strip 5. The retaining strip 8 has a groove 81, and the blocking strip 5 acts as a guide, guiding the groove 81 when the retaining strip 8 is inserted, thus replacing the original blocking function of the blocking strip 5. With this configuration, all retaining strips 8 are integrated through the connecting frame 7, allowing for convenient installation and removal. During use, the protective frame is the primary contact point with the cigarette pack; therefore, when cleaning is required, the protective frame can be removed separately for cleaning. This reduces cleaning time, labor intensity, and costs. It also prevents damage to the anti-adhesion wall surface inside the cigarette frame body 1 from cleaning tools. Furthermore, even if the cigarette frame body 1 cannot be completely cleaned, the frequency of cleaning is reduced, thus lowering labor costs and spare parts replacement costs.

[0030] For example, the bottom wall of the connecting frame 7 is provided with protrusions. These protrusions prevent the connecting frame 7 from fully fitting into the top opening of the cigarette frame body 1, thus avoiding difficulties during disassembly. In addition, the outer edge of the connecting frame 7 extends beyond the outer edge of the top opening of the cigarette frame body 1, which helps to apply force when disassembling the protective frame.

[0031] In this embodiment, the anti-sticking structure also includes a first rounded corner 21 and a second rounded corner 22. Adjacent wall panels of the inner frame 2 are transitioned by the first rounded corner 21; adjacent three wall panels of the inner frame 2 are transitioned by the second rounded corner 22. This design, by using the first rounded corner 21 and the second rounded corner 22 as transition points where straight lines intersect between wall panels, makes the transition between wall panels smoother, reduces dead angles formed by right-angle transitions between wall panels of the inner frame 2, reduces the possibility of tobacco material accumulating inside the inner frame 2, and indirectly improves the anti-sticking effect by preventing accumulation.

[0032] In this embodiment, the bottom end of the retaining strip 8 is fixedly connected to the support strip 6; in practice, this fixed connection can be achieved by welding or by using screws and nuts. Thus, the entire protective frame and support strip 6 can be disassembled in one operation. Disassembly and installation are convenient.

[0033] In this embodiment, the support bar 6 is a support shell 9 with a cavity 93. The top of the support shell 9 has a V-groove 91, and the top wall of the V-groove 91 has an air hole 92 that communicates with the cavity 93. The bottom wall of the V-groove 91 has a connecting notch 95 that connects the cavity to a through hole on the bottom wall of the cigarette frame body. This design allows the air hole to compensate for the impact of the support bar on the performance of the through hole, improving vacuuming efficiency and quality.

[0034] A positioning port 94 is machined at the bottom of the support shell 9. Positioning blocks are inserted into two corresponding through holes 4 in the inner frame. The positioning blocks position the positioning port 94, thereby limiting the position of the support shell 9. Simultaneously, a connecting notch 95 is provided at the bottom of the support shell 9, allowing the cavity 93 to connect with the through hole 4 on the bottom wall of the inner frame 2. During installation of the support shell 9, the positioning port 94 of the support shell 9 can be aligned with the positioning block; then, the support shell 9 and the retaining strip 8 are fixedly connected. Additionally, ventilation support shells 10 can be connected to both sides of the support shell 9. The structure of the ventilation support shells 10 is the same as that of the support shell 9. With this structure, during vacuum rehumidification of the tobacco bales, the support shell 9 can not only lift the tobacco bales; the connection of the through holes 4, connecting notch 95, cavity 93, and air holes 92 allows for supplemental ventilation; it does not affect the ventilation of the original through holes 4 in the inner frame 2 due to the installation of the support shell 9; this makes the flow of water vapor more uniform, improving the quality of the produced tobacco leaves.

[0035] The above provides a detailed description of a smoke frame for a vacuum rehumidifier provided by this utility model. The specific embodiments are described only to aid in understanding the method and core concept of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
