Description

Technical Field

[0001] This utility model relates to the field of tobacco processing technology, and in particular to a hot air circulating mouthpiece curing device. Background Technology

[0002] In the tobacco production process, the curing of cigarette filter rods is one of the key steps. Its purpose is to remove excess moisture from the filter rods by heating, so that the filter rod structure is stable and the hardness meets the standard, thereby ensuring the quality of subsequent cigarette filter rolling and the smoking experience. Existing hot air circulation filter rod curing devices have unreasonable hot air paths, and the carrier obstructs the penetration, causing uneven heating. Moreover, the hot air is mostly discharged in one direction, wasting heat and consuming a lot of energy. The lack of synchronous dehumidification makes it difficult to control the humidity in the curing chamber, affecting the curing effect and consistency. In terms of curing quality and conveying stability, the conveying structure is difficult to stably limit the filter rods, which can easily cause them to shift and stack. Rigid supports can also squeeze and deform the filter rods. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1: As shown in the attached document Figure 1 To be continued Figure 7 As shown:

[0027] This utility model provides a hot air circulation nozzle curing device, comprising: a curing chamber 1, with drive rollers 3 rotatably connected to the openings on both the front and rear sides of the curing chamber 1; a conveyor belt 4 wrapped around the outer side of the drive rollers 3; ventilation holes on the surface of the conveyor belt 4; and two rows of nozzle fixing brackets 401 evenly spaced on the surface of the conveyor belt 4, each row of nozzle fixing brackets 401 consisting of a stainless steel bracket with an arc-shaped top; a hot air circulation tank 2 on the right side of the curing chamber 1; hot air circulation channels 201 on both the upper and lower sides of the hot air circulation tank 2 communicating with the curing chamber 1; a dehumidification and heating component 5 installed inside the hot air circulation tank 2; and an outer protective shell 6 snapped onto the right side of the hot air circulation tank 2. Specifically, the drive rollers 3 cooperate with the conveyor belt 4 to realize the curing of the nozzles within the curing chamber. The stable conveying within the chamber 1, with ventilation holes in the conveyor belt 4 allowing hot air to penetrate the belt and fully contact the nozzles, avoids uneven heating in certain areas. The arc-shaped stainless steel nozzle fixing bracket 401 on the outer surface of the conveyor belt 4 not only firmly fixes the nozzles to prevent displacement and stacking during conveying, but also reduces pressure damage to the nozzle surface, ensuring the integrity of the nozzle shape after curing. The hot air circulation tank 2 is connected to the curing chamber 1 through the hot air circulation channels 201 on the upper and lower sides, forming a closed-loop hot air circulation path. In conjunction with the internal dehumidification and heating components 5, hot air heating and moisture removal are achieved simultaneously, avoiding heat loss caused by hot air exhaust and improving heat utilization. The outer shell 6 can protect the dehumidification and heating components 5 inside the hot air circulation tank 2, preventing external impurities from entering and affecting the operation of the equipment.

[0028] The curing chamber 1 has a rectangular structure with openings on both the front and rear sides. Conveying supports 101 are provided on both the front and rear sides of the curing chamber 1. Drive rollers 3 are rotatably connected to the ends of the conveying supports 101. Circulating air ducts 102 are provided on the upper and lower side walls of the curing chamber 1. A ventilation mesh plate 103 is provided on the side of the circulating air ducts 102 facing the interior of the curing chamber 1. Specifically, the curing chamber 1 adopts a rectangular structure with openings on both the front and rear sides, facilitating the passage of the conveyor belt 4 through the chamber body and enabling continuous feeding and discharging of the mouthpieces, thus meeting the needs of tobacco production line operations. The conveying supports 101 provide stable support for the drive rollers 3, preventing them from shifting or sinking when the conveyor belt 4 carries the weight of the mouthpieces, ensuring the long-term stability of the conveying mechanism. The circulating air ducts 102 on the upper and lower side walls of the curing chamber 1 are precisely connected to the hot air circulation channel 201 of the hot air circulation tank 2, forming an upper and lower hot air conveying path within the curing chamber 1. Combined with the ventilation mesh plate 103 on the side of the circulating air ducts 102 facing the interior of the chamber, the hot air can be evenly dispersed into the interior of the curing chamber 1, preventing the hot air from directly impacting the mouthpieces and causing localized overheating.

[0029] The hot air circulation tank 2 has hot air circulation channels 201 evenly spaced on the top left side, which connect to the circulation duct 102 at the top of the curing chamber 1. Similarly, the hot air circulation tank 2 has hot air circulation channels 201 evenly spaced on the bottom right side, which connect to the circulation duct 102 at the bottom of the curing chamber 1. A circulating fan 203 is installed inside the connection points of the hot air circulation tank 2 and the circulation duct 102. Specifically, the hot air circulation channels 201 on the top left side of the hot air circulation tank 2 connect to the top duct of the curing chamber 1, and the hot air circulation channels 201 on the bottom right side of the hot air circulation tank 2 connect to the bottom duct of the curing chamber 1. This asymmetrical layout guides the heat... The air forms an orderly flow path of "top left in, bottom right out" in the curing chamber 1. The circulating fan 203 installed inside the connection between the hot air circulation tank 2 and the circulation duct 102 provides stable power for hot air circulation, ensuring smooth flow of hot air in the hot air circulation channel 201 and the circulation duct 102. This effectively avoids problems such as poor hot air circulation or local areas without airflow caused by duct resistance. Multiple sets of equally spaced hot air circulation channels 201 can further improve the uniformity of hot air distribution. With the wind speed adjustment function of the circulating fan 203, it can adapt to the curing wind speed requirements of different nozzle specifications.

[0030] The hot air circulation chamber 2 has semi-circular baffles 202 symmetrically arranged on the left side of its front and rear inner walls. A dehumidification and heating component 5 is located on the right side of the baffles 202. The dehumidification and heating component 5 is assembled from a dehumidification baffle box 501 and a heating mesh plate 502. The dehumidification baffle box 501 is filled with a super absorbent. A cylindrical connecting rod 204 is fixedly connected to the middle of the right side of the front and rear outer walls of the hot air circulation chamber 2. Specifically, the circulated hot air flows back into the chamber through the hot air circulation channel 201 on the right side of the bottom of the hot air circulation chamber 2. When the air passes through the dehumidification baffle 501 of the dehumidification heating component 5, the dehumidification baffle 501 and the heating mesh plate 502 adopt a left-right assembly structure to realize the integrated design of dehumidification and heating functions. The super absorbent filled inside the dehumidification baffle 501 can efficiently absorb the moisture in the hot air, and the assembly structure makes it easy to disassemble and replace the absorbent later, or to perform maintenance operations on the heating mesh plate 502. The cylindrical connecting rod 204 fixed at the middle of the right side of the front and rear outer walls of the hot air circulation barrel 2 provides a stable connection point for the installation of the outer shell 6.

[0031] The outer casing 6 has a mesh structure on its right side wall. A connecting hook 601 is hinged at the middle of the left and right outer side walls of the outer casing 6. The bottom rear side of the connecting hook 601 is hooked and overlaps the connecting rod 204 of the hot air circulation tank 2. Specifically, the mesh structure on the right side wall of the outer casing 6 allows for slight ventilation between the inside of the hot air circulation tank 2 and the outside during equipment operation, preventing excessive pressure buildup inside the tank due to heating. It also prevents large impurities from entering and does not affect the normal operation of the dehumidification heating component 5. The connecting hook 601, hinged at the middle of the left and right outer side walls of the outer casing 6, is hooked and overlaps the connecting rod 204 of the hot air circulation tank 2. This design allows for quick disassembly and assembly of the outer casing 6. The outer casing 6 can be removed by flipping the connecting hook 601 upwards without the need for tools, greatly improving the convenience of later maintenance of the dehumidification heating component 5.

[0032] The specific usage and function of this embodiment are as follows:

[0033] When using this hot air circulating nozzle curing device, the nozzles to be cured are first placed on the two rows of arc-shaped stainless steel nozzle holders 401 on the surface of the conveyor belt 4. The rotation of the drive roller 3 drives the conveyor belt 4 to move, smoothly conveying the nozzles into the curing chamber 1 with front and rear openings. At this time, the hot air circulation tank 2 starts working. The internal dehumidification and heating component 5 first absorbs the moisture in the air through the super absorbent in the dehumidification baffle box 501, and then heats it through the heating mesh plate 502 to form dry hot air. The circulating fan 203 provides power for the hot air circulation, driving the hot air through the hot air circulation channel 201 on the top left of the hot air circulation tank 2 into the circulation duct 102 at the top of the curing chamber 1. After being evenly dispersed by the ventilation mesh plate 103 inside the duct, the hot air is then... The hot air acts on the nozzle, and after flowing in the chamber, it gathers from the circulation duct 102 at the bottom of the curing chamber 1. It then flows back into the chamber through the hot air circulation channel 201 on the right side of the bottom of the hot air circulation barrel 2, forming a closed-loop hot air circulation of "top left in - bottom right out". This ensures that the nozzle is cured in a stable temperature and dry environment. After the nozzle is cured, it can be sent out from the other side of the curing chamber 1 by the conveyor belt 4. If the dehumidification heating component 5 needs to be maintained, simply flip the connecting hooks 601 on the left and right side walls of the outer shell 6 upwards to detach them from the connecting rods 204 on the outer wall of the hot air circulation barrel 2. After removing the outer shell 6, the dehumidification baffle box 501 or the heating mesh plate 502 can be operated. After maintenance, the hooks can be reattached to reset the outer shell 6.

[0034] Example 2:

[0035] Multiple sets of parallel adjusting grooves are opened along the length of the conveyor belt 4. Sliding blocks are slidably connected in the adjusting grooves. Two rows of nozzle rod fixing brackets 401 are respectively fixed to the top of the corresponding sliders. Adjusting bolts are provided on both the left and right edges of the conveyor belt 4. The ends of the adjusting bolts pass through the sliders and are threaded to the inner wall of the adjusting grooves. A silicone buffer pad is attached to the arc-shaped inner side wall of the nozzle rod fixing bracket 401. By sliding the slider in the adjusting groove, the spacing between the two rows of fixing brackets can be adjusted according to nozzle rods of different diameters. After adjustment, tightening the adjusting bolts will lock the position, solving the problem of the original fixing bracket spacing being fixed and only suitable for nozzle rods of a single specification. The silicone buffer pad can further reduce the squeezing and friction of the fixing brackets on the nozzle rod surface, avoid indentation on the nozzle rod, and improve the fixing stability, preventing small-diameter nozzle rods from shaking during conveying.
