Description

Technical Field

[0001] This utility model relates to the field of tobacco curing technology, and in particular to a tobacco leaf quality sensor bracket for a tobacco curing barn. Background Technology

[0002] In recent years, with the rapid development of artificial intelligence and the Internet of Things, the realization of intelligent and information-based tobacco curing barns has become an inevitable development trend in the tobacco industry. The construction of intelligent curing barns relies heavily on the real-time acquisition of various data during the tobacco curing process. Among these, the quality changes during curing reflect changes in the moisture content of the tobacco leaves, making the quality data extremely important. Currently, there is no specialized equipment for collecting tobacco curing quality data. Furthermore, the commonly used 1-50kg weight sensors in the industry often experience wear and tear from the placed tobacco rods or clips, or slippage of the clips or rods from the sensors, leading to data acquisition failures.

[0003] A prior art utility model patent, CN221055860U, published on May 31, 2024, discloses a tobacco leaf curing weighing device, relating to the field of tobacco processing technology. It includes a U-shaped base with a U-shaped cavity at one end. A sensor element is mounted on the U-shaped base and disposed within the U-shaped cavity. A tobacco stem holder for hanging a tobacco leaf rack is positioned above the sensor element. Sensor pads are provided on both ends of the sensor element, symmetrically arranged around its center. One sensor pad's end away from the sensor element is connected to the U-shaped cavity, and the other end is connected to the tobacco stem holder. A fixing assembly is provided on the outer wall of the U-shaped base for fixation. While this patent can address the issue of auxiliary sensors bearing weight, inconvenient installation remains a problem in practical use. Utility Model Content

[0004] To address the shortcomings in the aforementioned background technology, this utility model provides a tobacco leaf quality sensor bracket for tobacco curing barns, which solves the problems of inconvenient sensor installation and easy detachment of the tobacco curing rod from the end in the prior art.

[0005] The technical solution of this utility model is implemented as follows: a tobacco curing barn tobacco leaf quality sensor bracket includes a bottom support for installing the quality sensor, a connector for connecting to the wall of the curing barn or the tobacco drying rack of the curing barn is provided on the bottom support, side limiting parts are symmetrically provided on the bottom support, and a supporting and protective part for installing on the quality sensor is provided between the two side limiting parts.

[0006] More preferably, the bottom support is a mounting plate with at least two screws, and the mass sensor is mounted on top of the mounting plate by the screws. The mounting plate assists in mounting the mass sensor on the wall of the drying oven or on a smoke rack.

[0007] More preferably, the mounting plate has symmetrically provided mounting through holes on its sidewalls that mate with the connectors. These mounting through holes are pre-drilled holes in the mounting plate, facilitating its installation.

[0008] More preferably, the connector is a cable tie, and the mounting plate is fixed to the tobacco drying rack in the curing barn by passing the cable tie through the mounting through hole. The cable tie is preferably a high-temperature resistant stainless steel cable tie, which can fix the mounting plate and the quality sensor to the tobacco curing barn while ensuring the stability of the binding under heat preservation.

[0009] More preferably, the connector is a self-drilling screw, which passes through the mounting hole to fix the mounting plate to the wall of the tobacco curing barn. The bottom of the mounting plate fits against the tobacco hanging protrusion on the wall of the curing barn, and then the self-drilling screw is passed through the mounting plate to fix it to the wall, thus completing the installation of the mounting plate. It should be noted that in use, the mass sensor fixed to the wall of the tobacco curing barn and the mass sensor fixed to the tobacco drying rack are used in pairs.

[0010] Furthermore, the side limiting member is at least one baffle post, which is fixedly connected to one side of the mounting plate. Preferably, the side limiting member is two vertical baffle posts, which are vertically installed on the mounting plate. The baffle posts are used to separate the cigarette holders on both sides to avoid affecting the readings of the quality sensor.

[0011] Furthermore, the baffle posts and mounting plates are integrally formed U-shaped structures. Preferably, the baffle posts and mounting plates on both sides are made of high-temperature resistant material to prevent heat deformation during the tobacco drying process. In use, the opening of the U-shaped structure faces upwards for easy placement of the tobacco drying rod.

[0012] More preferably, the supporting protective component includes a protective plate, on which mounting screws are provided and installed above the mass sensor. The protective plate, installed above the mass sensor, protects the mass sensor from wear during use.

[0013] Further preferably, the protective plate is provided with an arc-shaped groove for cooperating with the cigarette drying rod. The arc-shaped groove can assist the cigarette drying rod to move towards the lowest point of the arc-shaped groove, ensuring that the cigarette drying rod is always in the center position of the mass sensor during the load-bearing process, thereby ensuring the stability of the mass sensor value and avoiding the problem of the value range shifting due to the positional deviation of the cigarette drying rod on the mass sensor.

[0014] Further preferably, the height difference between the top plane of the protective plate and the top plane of the lateral limiting member is H, where H is 1~5cm. A preferred height difference H is 3cm. The diameter of a conventional tobacco drying rod is 4cm. This height difference between the protective plate and the lateral limiting post prevents the tobacco drying rod from falling off the quality sensor during the tobacco curing process.

[0015] The beneficial effects of this utility model are as follows: This utility model uses a bottom support and a protective support to connect with the quality sensor, thereby protecting the quality sensor and ensuring good quality data acquisition while also preventing wear and tear on the quality sensor from the tobacco rod or tobacco clip. The bottom support is equipped with a baffle post to protect the tobacco leaves, preventing displacement and slippage during subsequent loading and ensuring continuous quality data acquisition. The tobacco rod / tweezers placement area, with its central arc-shaped concave design, achieves dual compatibility with both the tobacco clip and the tobacco rod, adapting to various baking environments.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 and Figure 2As shown in Embodiment 1, a tobacco leaf quality sensor bracket for a tobacco curing barn includes a bottom support for mounting the quality sensor. The bottom support has a connector 3 for connecting to the wall of the curing barn or a tobacco drying rack. Side limiting members 4 are symmetrically arranged on the bottom support, and a supporting protective member for mounting the quality sensor is located between the two side limiting members 4. This invention uses the bottom support and supporting protective member to connect with the quality sensor, thus protecting the sensor and ensuring good quality data acquisition while preventing wear and tear on the sensor from the tobacco stem or clips. The connector 3 on the bottom support is used to install the quality sensor inside the curing barn, facilitating its installation and use.

[0023] In this embodiment, the bottom support is a mounting plate 1, which has at least two screws. The mass sensor is mounted on top of the mounting plate 1 using these screws. The mounting plate 1 assists in mounting the mass sensor onto the wall of the drying oven or a tobacco rack. The side wall of the mounting plate 1 has symmetrically arranged mounting through holes 2 that mate with the connector 3. These mounting through holes 2 are pre-drilled holes in the mounting plate 1 to facilitate its installation.

[0024] In this embodiment, the connector 3 is a cable tie, and the mounting plate 1 is fixed to the tobacco drying rack in the curing barn by passing the cable tie through the mounting through hole 2. The cable tie is preferably made of high-temperature resistant stainless steel, which ensures the stability of the binding while fixing the mounting plate 1 and the mass sensor to the curing barn and maintaining heat insulation. The connector 3 is a self-drilling screw, which passes through the mounting through hole 2 to fix the mounting plate 1 to the wall of the curing barn. The bottom of the mounting plate 1 fits against the tobacco hanging protrusion on the wall of the curing barn, and then the self-drilling screw is passed through the mounting plate 1 to fix it to the wall, thus completing the installation of the mounting plate 1. It should be noted that in use, the mass sensor fixed to the wall of the curing barn and the mass sensor fixed to the drying rack are used in pairs.

[0025] like Figure 2 and Figure 3As shown in Embodiment 2, a tobacco leaf quality sensor bracket for a tobacco curing barn includes a side limiting member 4 consisting of at least one baffle post, which is fixedly connected to one side of the mounting plate 1. Preferably, the side limiting member 4 consists of two vertical baffle posts, which are vertically installed on the mounting plate 1. The baffle posts separate the tobacco hanging rods on both sides to avoid affecting the quality sensor readings. The baffle posts and the mounting plate 1 are integrally formed U-shaped structures. Preferably, the baffle posts on both sides and the mounting plate 1 are made of high-temperature resistant material to prevent heat deformation during the tobacco curing process. In use, the opening of the U-shaped structure faces upwards, facilitating the placement of the tobacco hanging rods. The four baffle posts of the bottom support member protect the placed tobacco leaves, preventing displacement and slippage caused by subsequent tobacco loading, and ensuring continuous quality data acquisition. The installation and connection between the bottom support member and the supporting protective member protects the quality sensor, ensuring good quality data acquisition by the sensor while also preventing wear on the quality sensor from the tobacco rods or clips.

[0026] In this embodiment, the supporting protective component includes a protective plate 5, which is provided with mounting screws and is mounted above the mass sensor via these screws. The protective plate 5 is mounted above the mass sensor to protect it from wear and tear during use.

[0027] In this embodiment, the protective plate 5 is provided with an arc-shaped groove 6 for cooperating with the tobacco drying rod. The arc-shaped groove 6 assists the tobacco drying rod in moving towards the lowest point of the arc-shaped groove 6, ensuring that the tobacco drying rod is always in the center position of the mass sensor during the load-bearing process, thereby ensuring the stability of the mass sensor value and avoiding the problem of value range shifting due to the positional deviation of the tobacco drying rod on the mass sensor. The tobacco rod / tweezers placement area, with its central arc-shaped concave treatment, achieves dual compatibility with both the tobacco clip and the tobacco rod, adapting to various baking environments.

[0028] In this embodiment, the height difference between the top plane of the protective plate 5 and the top plane of the lateral limiting member is H, where H is 1~5cm. Preferably, the height difference H is 3cm. The diameter of a conventional tobacco drying rod is 4cm. The height difference between the protective plate 5 and the lateral limiting post prevents the tobacco drying rod from falling off the quality sensor during the tobacco curing process.

[0029] All other structures are the same as in Example 1.

[0030] like Figures 1-3 As shown in Embodiment 3, a tobacco leaf quality sensor bracket for a tobacco curing barn includes: a bottom support and a supporting protective component. The bottom support includes a bottom support 1, two M6*35 screws, two M4.8*45 self-drilling screws, and several plastic cable ties. The supporting protective component includes a supporting protective component 2 and two M6*30 screws.

[0031] Specifically, the bottom support can fix the lower part of the 1-50kg mass sensor, and the upper part of the protective support can fix the upper part of the 1-50kg mass sensor. Together, they form a protective bracket to fix and protect the mass sensor as a whole.

[0032] The bottom support component 1 has four partition posts 3 cast at the four corners above it. The bottom support component 1 has two M6 screw mounting holes 6 on one side above and below it. The bottom support component (1) has two mounting holes on each side.

[0033] Specifically, the four baffles on the lower support not only protect the placed tobacco leaves from the influence of subsequent tobacco leaves, but also prevent the placed tobacco clips or stems from slipping, thus ensuring that the quality sensor can continuously collect the quality of the tobacco leaves and guarantee the consistency of quality data. Simultaneously, the two M6*35 screws can be used to install and fix the 1-50kg quality sensor from below through the two M6 screw mounting holes 6 on the bottom support, thereby securing the lower part of the quality sensor to the lower support. The two M4.8*45 self-drilling screws can be used to install the bottom support on one side of the curing barn wall through the two mounting holes on the bottom support (M4.8 screw mounting holes), or the plastic cable ties can be used to install the bottom support at the tobacco hanging beam in the curing barn through the two mounting holes, thus achieving the arrangement of the quality sensor inside the curing barn after the support is installed.

[0034] The supporting protective component 2 has two M6 screw mounting holes 4 on one side at the top and bottom, and the cigarette rod / cigarette clip placement area 5 of the supporting protective component 2 is treated with a rounded concave shape.

[0035] Specifically, the two M6*30 screws can be used to install and fix the 1~50kg mass sensor from above through the two M6 screw mounting holes 4 of the supporting protective component, so as to fix the upper part of the mass sensor on the upper bracket. The cigarette rod / cigarette clip placement 5 with the central arc concave treatment can not only achieve dual compatibility of cigarette clip and cigarette rod, but also make the placed cigarette rod less prone to displacement, which is more conducive to the stable acquisition of mass data and makes the main body of the bracket adaptable to various baking environments.

[0036] The quality sensor brackets must be used in pairs. For collecting tobacco curing quality data, two sets of quality sensors are required. Both ends of the tobacco clip or stem to be measured must be placed simultaneously on the quality sensors on both sides to collect the data. Therefore, two sets of quality sensor brackets are also needed. After installing the quality sensors on the brackets, they must be placed on one side of the curing barn wall and one side of the middle tobacco hanging beam to meet the usage requirements.

[0037] Working Principle: When collecting data on the quality of tobacco curing, two 1-50kg mass sensors and two sets of sensor brackets are required. Then, using two M6*35 screws and two M6*30 screws, the 1-50kg mass sensors are fixed from the top and bottom sides through the two M6 screw mounting holes on the bottom support and the two M6 screw mounting holes on the protective support. Next, using two M4.8*45 self-drilling screws, one sensor is installed on one side of the curing barn wall through the two mounting holes on the bottom support. The other mass sensor is installed at the tobacco hanging beam in the curing barn using plastic cable ties through the two mounting holes on the bottom support. After installation, the ends of the tobacco clips or tobacco rods to be measured can be placed on the tobacco rods or clips on the upper bracket, thus achieving continuous data collection of tobacco curing quality and protecting the mass sensors.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
