Description

Technical Field

[0001] This utility model relates to the field of tobacco processing technology, and in particular to a vibrating groove mechanism. Background Technology

[0002] In the cigarette production process, the leaf moistening and feeding system is a key piece of equipment in the tobacco processing line. Its main purpose is to loosen, heat, and humidify the tobacco leaves, making them soft and loose, thereby enhancing their toughness and resistance to breakage. The heated and humidified tobacco leaves are typically conveyed forward via a vibrating trough during discharge.

[0003] Currently, during the production process, because the temperature of the conveying trough is lower than the temperature of the tobacco leaves after being heated and humidified by the drum, the warm tobacco leaves come into contact with the cooler conveying trough after being discharged from the drum. As the temperature of the tobacco leaves drops rapidly, some of the tobacco leaves cool and stick to the conveying trough, thus affecting the conveying and subsequent processing effects. Utility Model Content

[0004] The purpose of this utility model is to provide a vibrating trough mechanism that reduces the occurrence of tobacco leaves sticking to the conveying vibrating trough during cooling, thereby ensuring the quality of the tobacco leaves and subsequent processing.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] The vibrating groove mechanism, located at the outlet end of the leaf feeding system, includes:

[0007] The conveying trough can be connected to the discharge port of the leaf feeding system and can reciprocate to complete the conveying of the tobacco leaves.

[0008] A heating component is disposed in the conveying trough. When the heating component is operated, it can increase the temperature inside the conveying trough.

[0009] As a further technical solution, the heating component is disposed on the outer wall of the bottom plate of the conveying trough.

[0010] As a further technical solution, the heating assembly includes a heating element and a heating tube, the heating element being connected to the heating tube for heating the heating tube, and the heating tube being configured as a coil.

[0011] As a further technical solution, the heating element is configured as an electric heater, and the electric heater is electrically connected to the heating tube.

[0012] As a further technical solution, the heating element is configured as a fluid heater, and the inlet of the heating tube is connected to the fluid outlet of the fluid heater.

[0013] As a further technical solution, the heating assembly also includes a liquid storage device, the inlet of which is connected to the outlet of the heating tube, and the outlet of which is connected to the fluid inlet of the fluid heater.

[0014] As a further technical solution, the heating assembly also includes a temperature sensor, which is disposed in the conveying groove and is communicatively connected to the heating element.

[0015] As a further technical solution, the vibrating trough mechanism also includes a heat insulation cover, which is installed on the outer wall of the bottom plate of the conveying vibrating trough, and the heat insulation cover is provided with a clearance through hole that allows the heating tube to pass through.

[0016] As a further technical solution, the opening end of the heat insulation cover is provided with an auxiliary flange that can be connected to the bottom wall of the conveying trough, and the auxiliary flange extends in a ring shape along the circumference of the heat insulation cover.

[0017] As a further technical solution, the vibrating trough mechanism also includes a heat insulation component, which is disposed on the outer wall of the side plate of the conveying vibrating trough.

[0018] Compared with the prior art, the technical advantages of the vibrating groove mechanism provided by this utility model are as follows:

[0019] Because the heating element is located in the conveying trough, it is activated before the heated tobacco leaves arrive at the trough from the moistening feeding system. This raises the temperature within the trough, ensuring it matches the temperature of the tobacco leaves to be delivered. Consequently, the temperature of the heated tobacco leaves upon arrival is reduced, minimizing the risk of them sticking to the trough due to rapid temperature drops, thus ensuring optimal quality for both the tobacco leaves and subsequent processing.

[0028] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0029] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0030] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0031] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0032] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0033] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0034] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0035] Combination Figure 1 and Figure 2 As shown, the vibrating trough mechanism provided in this embodiment is disposed at the discharge port end of the leaf-moistening feeding system (not shown in the figure). This vibrating trough mechanism reduces the occurrence of the head tobacco leaves sticking to the conveying vibrating trough 100 during cooling, ensuring the effect of the head tobacco leaves and subsequent processing. Specifically, the vibrating trough mechanism includes a conveying vibrating trough 100 and a heating component 200: the conveying vibrating trough 100 can communicate with the discharge port of the leaf-moistening feeding system; the heating component 200 is disposed in the conveying vibrating trough 100, and the operation of the heating component 200 can increase the temperature inside the conveying vibrating trough 100.

[0036] Since the heating component 200 is located in the conveying trough 100, the heating component 200 is activated before the heated tobacco leaves arrive at the conveying trough 100 from the moistening feeding system. This raises the temperature within the conveying trough 100, ensuring that the temperature inside the conveying trough 100 matches the temperature of the tobacco leaves to be delivered. Consequently, after the heated tobacco leaves arrive at the conveying trough 100, the likelihood of the leaves sticking to the conveying trough 100 due to a rapid temperature drop is reduced, thus ensuring the quality of the tobacco leaves and subsequent processing.

[0037] Preferably, the heating component 200 is disposed on the outer wall of the bottom plate of the conveying trough 100. This arrangement ensures the heating effect of the heating component 200 on the conveying trough 100, reducing the occurrence of the tobacco leaves cooling and sticking inside the conveying trough 100; on the other hand, it avoids interference between the heating component 200 and the tobacco leaves, which would affect the conveying efficiency of the tobacco leaves.

[0038] Preferably, the heating assembly 200 includes a heating element and a heating tube 210. The heating element is connected to the heating tube 210 and is used to heat the heating tube 210. The heating tube 210 is configured as a coil. The heating element heats the heating tube 210 to achieve the heating process of the conveying trough 100. By configuring the heating tube 210 as a coil, the contact area between the heating tube 210 and the conveying trough 100 can be increased, improving heating efficiency while ensuring heating effect and reducing the possibility of the tobacco leaves sticking in a certain area of ​​the conveying trough 100 due to excessive temperature differences in different parts of the conveying trough 100. The form of the coil can be set as serpentine, disc, etc., according to actual needs, and is not specifically limited here.

[0039] Regarding the arrangement of the heating element, this embodiment provides two implementation methods, specifically:

[0040] The first type, such as Figure 1 As shown, the heating element is an electric heater 220, which is electrically connected to the heating tube 210. The electric heater 220 heats the heating tube 210 with electrical energy to heat the conveying trough 100, and the heating speed is fast and highly adjustable.

[0041] The second type, such as Figure 2 As shown, the heating element is configured as a fluid heater (not shown in the figure), and the inlet of the heating pipe 210 is connected to the fluid outlet of the fluid heater. After the fluid medium is heated in the fluid heater, it flows into the heating pipe 210 through the fluid outlet to heat the conveying trough 100 and ensure that the heating effect is the same at all parts of the bottom plate of the conveying trough 100.

[0042] Furthermore, the heating assembly 200 also includes a liquid storage device (not shown in the figure). The inlet of the liquid storage device is connected to the outlet of the heating pipe 210, and the outlet is connected to the fluid inlet of the fluid heater. By setting up the liquid storage device, during the heating and heat preservation process of the conveying vibrating trough 100, the fluid medium flows into the heating pipe 210 to complete the heating process. When it is not necessary to heat and preserve the conveying vibrating trough 100, the fluid medium in the heating pipe 210 is stored in the liquid storage device. When the fluid medium stored in the liquid storage device is sufficient, it is transported to the fluid heater through the fluid inlet. In this way, the fluid medium can be recycled to further reduce costs. At the same time, it avoids the fluid medium flowing out of the heating pipe 210 from directly entering the fluid heater, thus preventing an increase in the real-time operating pressure of the fluid heater. In addition, to further improve the flow effect of the fluid medium, valves and liquid pumps can be installed at the inlet and outlet of the heating pipe 210. The specific structure and working principle of the valves and liquid pumps refer to the prior art and are not specifically limited here.

[0043] In both of the above embodiments, the heating component 200 further includes a temperature sensor 230, which is disposed in the conveying trough 100 and is communicatively connected to the heating element.

[0044] By setting a temperature sensor 230 to sense the real-time temperature within the conveying trough 100, when the real-time temperature within the conveying trough 100 is lower than the target temperature, the temperature sensor 230 sends a heating signal to the heating element to activate it promptly, thereby raising the real-time temperature within the conveying trough 100 to the target temperature. When the real-time temperature within the conveying trough 100 is higher than the target temperature, the temperature sensor 230 sends a cooling signal to the heating element, causing it to stop operating, thus cooling the conveying trough 100 until the real-time temperature within the conveying trough 100 is the same as the target temperature. In this way, the temperature sensor 230 and the heating element work together to further reduce the probability of the tobacco leaves sticking to the conveying trough 100 during cooling.

[0045] Preferably, the vibrating trough mechanism further includes a heat insulation cover 300, which covers the outer wall of the bottom plate of the conveying vibrating trough 100, and the heat insulation cover 300 is provided with a clearance through hole 310 that allows the heating pipe 210 to pass through. One end of the heating pipe 210 extends out of the heat insulation cover 300 through the clearance through hole 310 to facilitate connection with the heating element and avoid interference between the heating element and the heat insulation cover 300. By setting the heat insulation cover 300, the amount of heat dissipated from below the conveying vibrating trough 100 is reduced during the heating process of the heating pipe 210, so as to ensure the heating and heat preservation effect of the conveying vibrating trough 100.

[0046] Preferably, the open end of the insulation cover 300 is provided with an auxiliary flange 320 that can be connected to the bottom wall of the conveying vibration trough 100. The auxiliary flange 320 extends in a ring shape along the circumference of the insulation cover 300. The auxiliary flange 320 is detachably connected to the bottom plate of the conveying vibration trough 100 via a threaded connector, ensuring the connection strength and stability of the insulation cover 300, thereby ensuring the insulation effect on the heating pipe 210; at the same time, it reduces the connection difficulty of the insulation cover 300 to the bottom plate of the conveying vibration trough 100 and reduces processing and assembly costs. In other embodiments, the connection method of the insulation cover 300 to the bottom plate of the conveying vibration trough 100 can also be selected by welding, bonding, etc., according to actual needs.

[0047] Preferably, the vibrating trough mechanism further includes a heat insulation component 400, which is disposed on the outer wall of the side plate of the conveying vibrating trough 100. By providing the heat insulation component 400 on the outer wall of the side plate of the conveying vibrating trough 100, the amount of heat dissipated from the side plate of the conveying vibrating trough 100 is reduced, thereby further improving the heating and heat preservation effect of the conveying vibrating trough 100. The specific material of the heat insulation component 400 is not limited, and can be set as heat insulation cloth, heat insulation cotton, heat insulation foam, etc., according to actual needs.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
