Abstract
Description
Technical Field
[0001] This utility model relates to the field of tobacco equipment technology, and in particular to a pull-out discharge cover for a heating and humidifying device. Background Technology
[0002] In the field of heating and humidification equipment in tobacco processing workshops, existing technologies typically employ flexible rubber curtain discharge hoods at the discharge end to prevent material from spraying outwards, ensuring a good seal. However, these flexible rubber curtain discharge hoods have several drawbacks: First, the flexible material of the hood easily develops wrinkles at the corners that are difficult to clean. These wrinkles become accumulation sites for dirt, potentially leading to serious quality risks such as mold and insect infestations over time. Second, the single-piece rubber discharge hood lacks ventilation holes, making it impossible to balance the air pressure inside and outside the hood when the vibrating trough moves up and down. This causes some tobacco leaves to spray out between the hood and the vibrating trough, resulting in material waste and increased production costs. Third, in the high-temperature and high-humidity environment of the tobacco processing workshop, rubber products are prone to accelerated aging, and the discharge hood is susceptible to cracking or detachment, allowing impurities to enter the tobacco leaves and posing a product quality risk. Furthermore, due to the structural characteristics of the flexible rubber curtain discharge hood, its cleaning and maintenance are also quite difficult, consuming significant manpower and resources with limited effectiveness. Utility Model Content
[0003] In view of this, the present invention provides a pull-out discharge hood for a heating and humidifying device, which can solve the technical problems of the discharge hood in the prior art, such as the generation of hard-to-clean dirt dead corners, the inability to ventilate causing an imbalance of internal and external pressure leading to material spraying and waste, the easy aging and detachment in high temperature and high humidity environments, and the high maintenance difficulty.
[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:
[0005] A pull-out discharge hood for a heating and humidifying device includes a discharge hood frame. The top of the discharge hood frame is connected to the discharge end of the heating and humidifying device, and the bottom of the discharge hood frame is connected to the inlet end of a vibrating trough. The discharge hood frame includes symmetrically arranged left and right metal baffles. The rear ends of the left and right metal baffles are connected together by a rear metal baffle, and the front ends of the left and right metal baffles are connected together by a flexible curtain. The left, right, and rear metal baffles and the flexible curtain form a material conveying channel connecting the discharge end of the heating and humidifying device with the inlet end of the vibrating trough. The surfaces of the left, right, and rear metal baffles are evenly covered with metal mesh, and the tops of the left and right metal baffles are evenly provided with push-pull slide rails so that the discharge hood frame can be pulled out relative to the discharge end of the heating and humidifying device.
[0006] As an improvement to the above technical solution, the left metal baffle, right metal baffle, rear metal baffle, metal mesh and push-pull slide rail are all made of 304 stainless steel, which not only has excellent corrosion resistance and oxidation resistance, adapts to the hygiene and durability requirements of food production equipment, but also provides stable support for the overall structure.
[0007] As an improvement to the above technical solution, the flexible curtain is made of food-grade flexible rubber material and is evenly divided into several curtain units so that the material can pass through more smoothly during discharge and reduce the possibility of material blockage.
[0008] As an improvement to the above technical solution, the left and right metal baffles are each equipped with two metal meshes, and the rear metal baffle is equipped with one metal mesh. The surface of the metal meshes is provided with mesh holes. The metal meshes not only prevent material overflow, but also balance the air pressure inside and outside the discharge hood frame through the mesh holes, thus avoiding the situation where material is sprayed out between the bottom of the discharge hood frame and the feed end of the vibrating trough during the vibration process due to air pressure difference.
[0009] As an improvement to the above technical solution, two push-pull slide rails are provided. The two push-pull slide rails are respectively arranged on the top surface of the left metal baffle and the right metal baffle. The bottom surface of the discharge end of the heating and humidifying equipment is provided with a slider corresponding to the arrangement position of the push-pull slide rails. The push-pull slide rails and sliders cooperate to form a push-pull sealing structure. The discharge hood frame moves to pull relative to the discharge end of the heating and humidifying equipment, which improves the convenience of maintenance, effectively reduces the intensity of maintenance, improves the efficiency of maintenance work, and eliminates maintenance dead corners, avoiding potential quality problems.
[0010] Compared with the prior art, the technical solution of this utility model has the following advantages:
[0011] This utility model features a reasonable structural design, strong practicality, convenient use, and low maintenance difficulty. By incorporating components made of 304 stainless steel, it eliminates the space for dirt accumulation at the source, effectively reducing quality risks such as mold and insect infestation. Furthermore, it is not prone to aging in high temperature and humidity environments, preventing impurities from contaminating the tobacco leaves and ensuring product quality. The metal mesh not only prevents material overflow but also balances the air pressure inside and outside the discharge hood frame through its mesh openings, preventing material from being ejected between the bottom of the discharge hood frame and the feed end of the vibrating trough during vibration due to pressure differences, thus reducing material waste and lowering material consumption in the production process. The pull-out design of this utility model enhances maintenance convenience, effectively reduces maintenance intensity, improves maintenance efficiency, and eliminates maintenance blind spots, avoiding potential quality problems.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0021] like Figures 1 to 3 As shown, this utility model provides a pull-out discharge hood for a heating and humidifying device.
[0022] It includes a discharge hood frame, the top of which is connected to the discharge end of the heating and humidifying equipment, and the bottom of which is connected to the inlet end of the vibrating trough. The discharge hood frame includes a left metal baffle 1 and a right metal baffle 2 symmetrically arranged. The rear ends of the left metal baffle 1 and the right metal baffle 2 are connected together by a rear metal baffle 3, and the front ends of the left metal baffle 1 and the right metal baffle 2 are connected together by a flexible curtain 4, so that the left metal baffle 1, the right metal baffle 2, the rear metal baffle 3 and the flexible curtain 4 form a material conveying channel connecting the discharge end of the heating and humidifying equipment and the inlet end of the vibrating trough. The surfaces of the left metal baffle 1, the right metal baffle 2 and the rear metal baffle 3 are evenly distributed with metal mesh 5, and the top ends of the left metal baffle 1 and the right metal baffle 2 are evenly distributed with push-pull slide rails 6, so that the discharge hood frame can be pulled out relative to the discharge end of the heating and humidifying equipment.
[0023] In the embodiments described in this utility model, the left metal baffle 1, the right metal baffle 2, the rear metal baffle 3, the metal mesh 5, and the push-pull slide rail 6 are all made of 304 stainless steel, which not only has excellent corrosion resistance and oxidation resistance, and meets the hygiene and durability requirements of food production equipment, but also provides stable support for the overall structure.
[0024] In the embodiments described in this utility model, the flexible curtain 4 is made of food-grade flexible rubber material. The flexible curtain 4 is evenly divided into several curtain units so that the material can pass through more smoothly when discharging, reducing the possibility of material blockage.
[0025] In the embodiments described in this utility model, the surface of the left metal baffle 1 and the right metal baffle 2 are each provided with two metal meshes 5, and the surface of the rear metal baffle 3 is provided with one metal mesh 5. The surface of the metal mesh 5 is provided with mesh holes. The metal mesh 5 can not only prevent material from overflowing, but also balance the air pressure inside and outside the discharge hood frame through the mesh holes on the surface of the metal mesh 5, so as to avoid the situation where the material is sprayed out between the bottom end of the discharge hood frame and the feed end of the vibrating trough during the vibration of the vibrating trough due to the air pressure difference.
[0026] In the embodiments described in this utility model, two push-pull slide rails 6 are provided. The two push-pull slide rails 6 are respectively arranged on the top surfaces of the left metal baffle 1 and the right metal baffle 2. The bottom surface of the discharge end of the heating and humidifying equipment is provided with a slider corresponding to the arrangement position of the push-pull slide rail 6. The push-pull slide rail 6 and the slider cooperate to form a push-pull sealing structure. The discharge cover frame moves in a pulling motion relative to the discharge end of the heating and humidifying equipment, which improves the convenience of maintenance, effectively reduces the intensity of maintenance, improves the efficiency of maintenance work, and eliminates maintenance dead corners, avoiding potential quality problems.
[0027] Based on the above, the working principle of this utility model is as follows:
[0028] During production, the material enters the discharge hood frame from the discharge end of the heating and humidifying equipment. Due to the balancing effect of the metal mesh 5 on the surface of the left metal baffle 1, right metal baffle 2 and rear metal baffle 3 on the internal and external air pressure, the material smoothly enters the material conveying channel to the feed end of the vibrating trough under a relatively stable air pressure environment. Under the vibration conveying action of the vibrating trough, the material moves forward to the flexible curtain 4. The flexible curtain 4, which is divided into several curtain units, can be easily pushed open by the material due to its good flexibility and deformability, so that the material can smoothly move towards the discharge end of the vibrating trough.
[0029] After production is completed, the maintenance phase begins. Operators use the push-pull slide rail 6 to pull the discharge hood frame out from between the discharge end of the heating and humidifying equipment and the feed end of the vibrating trough. Then, they clean the accumulated material on the surface of the vibrating trough below the discharge end of the heating and humidifying equipment, and clean and maintain the conveying plane of both the discharge end and the vibrating trough. After cleaning, the discharge hood frame is pushed back to its original position using the push-pull slide rail 6. The sealing contact between the discharge hood frame and both the discharge end and feed end of the heating and humidifying equipment is checked for good quality. If no problems are found, the equipment can resume normal production.
[0030] The following statistics were compiled comparing the maintenance time of using the old discharge hood with that of using the new invention in actual production activities:
[0031]
[0032] As shown in the table, the average maintenance time using the old discharge hood is 363.8 seconds, while the average maintenance time using this utility model is 168.8 seconds. Using this utility model effectively reduces the maintenance intensity and improves the efficiency of maintenance work.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
