Description

TECHNICAL FIELD

[0001] The utility model relates to tobacco processing equipment technical field especially, relates to an easy cleaning's vacuum moisture turnover box. BACKGROUND

[0002] Vacuum moisture is the key procedure on the tobacco industry silk production line, and its main role is to increase the moisture content and temperature of tobacco sheet, make tobacco sheet soft, easily loose, improve the processing resistance of tobacco sheet, and can reduce the green smell of tobacco leaves, improve the sensory quality. The process flow of vacuum moisture is generally that after the tobacco bale is removed from the box skin by the box opening machine, it enters the slicing machine for slicing treatment through the conveying belt and the moving trolley, and after the slicing is weighed and measured by the electronic scale, it is loaded into the turnover box, the turnover box is conveyed to the vacuum moisture machine through the roller conveyor, and after the vacuum moisture treatment, the tobacco leaves are poured into the feeder through the box turnover machine and are sent to the next production procedure. In this process, the steel turnover box is usually used to hold the tobacco leaves, so that the opened tobacco leaves can be transferred in the whole system.

[0003] According to the working principle and process requirements of the vacuum moisture machine, the vacuum moisture process includes four links of vacuum pumping, steam humidification, heat preservation and back pumping. In the vacuum moisture processing process, when the temperature in the box reaches the set temperature after vacuum pumping, the humidification steam is started to be applied, part of the steam is absorbed by the tobacco leaves, and the rest is converted into condensed water at the bottom of the vacuum machine box. Since the bottom of the traditional turnover box is a stainless steel mesh, the condensed water vapor at the bottom of the vacuum machine box continuously humidifies the tobacco leaves on the box bottom through the gap of the stainless steel mesh until the end of the vacuum moisture processing process. In this process, the tobacco leaves at the bottom of the box are prone to water stains, and due to the action of tobacco oil, tobacco oil stains are formed and adhere to the stainless steel mesh surface at the bottom of the turnover box. In the process of turning over the turnover box to the feeder, the adhered tobacco stains cannot be completely poured clean, which causes difficulty in manual cleaning and makes it difficult to clean completely. If the tobacco leaves remaining at the bottom of the turnover box re-enter the vacuum moisture machine for multiple times of moisture, it is easy to cause the tobacco leaves to deteriorate and rot, affecting the quality of the product. SUMMARY

[0004] The purpose of the utility model embodiment is to provide an easy-to-clean vacuum moisture turnover box, which is convenient to clean and can improve the quality of tobacco leaves.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An easy-to-clean vacuum moisture turnover box is provided, which comprises a box body and a gauze net. The box body comprises a base and side net plates arranged around the base. Each side net plate is provided with a gauze net on the outer side. The gauze net is adjacent to the lower end of the side net plate. The base is a non-mesh structure, and the side net plates and the gauze net are mesh structures. The mesh size of the gauze net is smaller than that of the side net plates.

[0007] As a further improvement to the easy-to-clean vacuum rehumidification turnover box, the mesh diameter of the screen is 0.1-0.2mm, and the mesh diameter of the side screen is 18-25mm.

[0008] As a further improvement to the easy-to-clean vacuum rehumidification turnover box, the mesh diameter of the screen is 0.15mm, and the mesh diameter of the side screen is 20mm.

[0009] As a further improvement to the easy-to-clean vacuum rehumidification turnover box, the mesh is made of stainless steel.

[0010] As a further embodiment of the easy-to-clean vacuum rehumidification turnover box, the base includes a rectangular annular bottom frame and a non-mesh panel. The panel is fixed to the bottom frame, and the side mesh is vertically fixed to the bottom frame and arranged around the panel. The mesh is connected to the side mesh and the bottom frame through connectors.

[0011] As a further embodiment of the easy-to-clean vacuum rehumidification turnover box, the box body also includes a plurality of reinforcing ribs spaced apart from top to bottom. The plurality of reinforcing ribs are arranged around the outer periphery of the four side mesh panels, and the mesh is fixedly connected to the reinforcing ribs and the bottom frame through the connectors.

[0012] As a further embodiment of the easy-to-clean vacuum rehumidification turnover box, the connector includes an upper pressure strip, a lower pressure strip, and a plurality of rivets. The upper edge of the mesh is located between the outer periphery of the lowermost reinforcing rib and the upper pressure strip and is locked by the plurality of rivets.

[0022] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0025] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationships shown in the accompanying drawings. They are used solely for ease of description and simplification of operation, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc., are merely used for distinction in description and have no special meaning.

[0026] like Figure 1 and Figure 2 As shown, the easy-to-clean vacuum rehumidification turnover box in this embodiment includes a box body 1 and a mesh 2. The box body 1 includes a base 11 and side mesh panels 12 surrounding the base 11. Each side mesh panel 12 has a mesh 2 on its outer side. The mesh 2 is adjacent to the lower end of the side mesh panel 12. The base 11 is a non-mesh structure, while the side mesh panels 12 and the mesh 2 are both mesh structures, and the mesh size of the mesh 2 is smaller than that of the side mesh panel 12.

[0027] In this embodiment, by setting the base 11 of the box 1 to a non-mesh structure, condensation caused by the application of humidifying steam during vacuum rehumidification can be blocked. This improves the situation in traditional vacuum rehumidification turnover boxes where condensation passes through the bottom mesh of the vacuum rehumidification turnover box for a long time to humidify the tobacco leaves. A mesh 2 with a mesh size smaller than that of the side mesh plate 12 is set on the outer periphery of the adjacent lower side mesh plate 12. This can be used to reduce the amount of humidifying steam entering the vacuum rehumidification turnover box and forming condensation, thereby reducing the adhesion of tobacco leaves to the turnover box, making it easier to clean the vacuum rehumidification turnover box, and improving the quality of the tobacco leaves.

[0028] Furthermore, the mesh diameter of the screen 2 is 0.1-0.2mm, and the mesh diameter of the side screen 12 is 18-25mm. This structural design can effectively reduce the amount of humidifying steam entering the chamber 1.

[0029] The mesh diameter of the side mesh plate 12 of the traditional vacuum rehumidification turnover box is 20mm. In this embodiment, the mesh diameter of the gauze 2 is designed to be 0.15mm, which can block most of the humidifying vapor from the outside of the box body 1.

[0030] In this embodiment, the mesh 2 is made of stainless steel to prevent the mesh 2 from rusting in a humid atmosphere for a long time and to improve the service life of the mesh 2.

[0031] Furthermore, the base 11 includes a rectangular annular bottom frame 111 and a non-mesh panel 112. The panel 112 is fixed to the bottom frame 111, and the side mesh panel 12 is vertically fixed to the bottom frame 111 and surrounds the panel 112. The mesh 2 is connected to the side mesh panel 12 and the bottom frame 111 through the connector 3.

[0032] The panel 112 and side mesh 12 of the traditional vacuum rehumidification turnover box are also mesh structures. Compared with the prior art, this embodiment designs the panel 112 as a non-mesh structure. That is, the non-mesh panel 112 is fixed on the bottom frame 111 (covering the internal area enclosed by the bottom frame 111 and the upper surface area of ​​the bottom frame 111 adjacent to its inner periphery). As a load-bearing body for carrying tobacco leaves, it can effectively block condensation and improve the quality of tobacco leaves.

[0033] Furthermore, panel 112 is made of stainless steel, which provides rust protection.

[0034] For example, this embodiment is an improvement on the traditional vacuum rehumidification turnover box, namely, fixing a non-mesh panel 112 directly on top of the mesh panel, which can effectively reduce the structural improvement cost of the vacuum rehumidification turnover box.

[0035] Furthermore, the box body 1 also includes a plurality of reinforcing ribs 13 spaced apart from top to bottom. The plurality of reinforcing ribs 13 are arranged around the outer periphery of the four side mesh panels 12. The mesh 2 is fixedly connected to the reinforcing ribs 13 and the bottom frame 111 through connectors 3.

[0036] Among them, the reinforcing rib 13 is a conventional structure of traditional vacuum rehumidification turnover box. In this embodiment, the mesh 2 is attached to the reinforcing rib 13 and the bottom frame 111. The mesh 2 can be quickly fixed to the outer periphery of the side mesh plate 12 by the connector 3, and the mesh 2 is easy to install.

[0037] Furthermore, the connector 3 includes an upper pressure strip 31, a lower pressure strip 32, and multiple rivets (not shown in the figure). The upper edge of the mesh 2 is located between the outer periphery of the lowermost reinforcing rib 13 and the upper pressure strip 31 and is locked by multiple rivets. The lower edge of the mesh 2 is located between the outer periphery of the bottom frame 111 and the lower pressure strip 32 and is locked by multiple rivets.

[0038] Before installing the mesh 2, design upper pressure strips 31 and lower pressure strips 32 of appropriate width according to the vertical width of the reinforcing ribs 13 and the bottom frame 111, and pre-set multiple connecting holes at intervals on the upper pressure strips 31 and lower pressure strips 32. When installing the mesh 2, first, press the upper edge of the mesh 2 tightly against the outer periphery of the lowest reinforcing rib 13 and press the lower edge of the mesh 2 tightly against the outer periphery of the bottom frame 111. Then, align the upper pressure strip 31 with the corresponding reinforcing rib 13 and press it tightly. Use rivets to pass through the connecting holes and screw them into the reinforcing rib 13, thereby securing the upper edge of the mesh 2 to the outer periphery of the lowest reinforcing rib 13. Then, use the same method to secure the lower edge of the mesh 2 to the outer periphery of the bottom frame 111. The specific details are not described here.

[0039] Furthermore, the outer periphery of the bottom frame 111 is flush with the outer periphery of the reinforcing rib 13. This structural design allows the upper and lower edges of the mesh 2 to be tightly attached to the outer periphery of the reinforcing rib 13 and the outer periphery of the bottom frame 111, respectively, thereby improving the installation stability of the mesh 2.

[0040] In this embodiment, both the upper pressure strip 31 and the lower pressure strip 32 are stainless steel pressure strips to improve the service life of the upper pressure strip 31 and the lower pressure strip 32 and improve the installation stability of the mesh 2.
