Description

Technical Field

[0001] This utility model relates to the field of constant temperature and humidity chamber technology, and in particular to a suspension device for a constant temperature and humidity chamber. Background Technology

[0002] In the cigarette production process, to ensure cigarette quality, it is necessary to test the physical properties of cigarette paper samples, including cigarette paper, tipping paper, and forming paper. During testing, the temperature and moisture content of these cigarette paper samples vary due to environmental influences, causing errors in the testing and reducing accuracy. Therefore, constant temperature and humidity chambers are often used to establish a uniform environment for storing cigarette paper samples, ensuring consistency in temperature and moisture content among different samples during storage and minimizing the impact of the environment on the test results.

[0003] The existing metal shelves in the constant temperature and humidity chamber have the following problems: First, it is inconvenient to place cigarette paper samples, requiring the chamber door to be opened for a long time, which leads to abnormal fluctuations in temperature and humidity inside the constant temperature and humidity equipment, often triggering alarms; second, it is difficult to ensure that the cigarette paper samples are evenly arranged, resulting in insufficient contact between the cigarette paper samples and the regulating airflow, which cannot guarantee the accuracy of the test results. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a suspension device for a constant temperature and humidity chamber, which solves the problems of inconvenience in placing cigarette paper samples and difficulty in ensuring uniform arrangement of cigarette paper samples in the use of metal shelves in the prior art.

[0005] This utility model solves the above-mentioned technical problems through the following technical means: a suspension device for a constant temperature and humidity chamber, which is set inside the constant temperature and humidity chamber, includes a guide rail frame and a suspension frame. The guide rail frame includes symmetrically opened grooved guide rails. The bottom of the suspension frame is provided with a slider that slides in cooperation with the grooved guide rails. A number of supports are symmetrically and evenly distributed on the suspension frame. Cantilever arms are inserted into the supports on both sides. A number of clamping mechanisms for clamping cigarette paper samples are evenly distributed on the cantilever arms.

[0006] Optionally, the clamping mechanism includes a fixed plate and a movable plate, the middle of which is rotatably connected relative to the fixed plate, and a spring is provided between the fixed plate and the movable plate. This facilitates the clamping of strip-shaped paper patterns.

[0007] Optionally, the contact surfaces of the fixed plate and the movable plate with the cigarette paper sample are made of silicone. This ensures the stability of the paper sample while preventing damage to it.

[0008] Optionally, the hanging frame is provided with several stabilizing mechanisms for stabilizing the cigarette paper sample. Each stabilizing mechanism includes a fixed back plate and a round strip snapped onto the back plate. By using the round strip to snap into the back plate and clamp the paper sample, the contact area between the paper sample and the round strip is small, allowing for a certain degree of relative sliding and reducing the possibility of the airflow forcibly tearing and damaging the paper sample.

[0009] Optionally, the guide rails and suspension brackets can be arranged in a multi-layered structure, with the cantilever arms between adjacent guide rails staggered. This ensures that all suspended cigarette paper samples are in full contact with the regulated airflow at the bottom of the constant temperature and humidity chamber.

[0010] Optionally, the cantilever is U-shaped and includes two vertical rods inserted into the support and a horizontal rod for mounting the clamping mechanism.

[0011] Optionally, the grooved guide rail has a dovetail groove structure. The suspension bracket is constrained by the dovetail groove structure and will not wobble.

[0012] Optionally, a reinforcing crossbeam is provided between the grooved guide rails, and a handle is provided on the outer side of the reinforcing crossbeam. The suspension bracket can be slid in and out using the handle, making operation convenient.

[0013] The beneficial effects of this utility model are:

[0014] This invention features a guide rail frame and a suspension frame inside a constant temperature and humidity chamber. The guide rail frame has symmetrically arranged grooved guide rails, and the bottom of the suspension frame has a slider that slides along the grooved guide rails, allowing for quick disassembly. The cantilever of the suspension frame is evenly distributed with clamping mechanisms for holding cigarette paper samples and stabilizing mechanisms for maintaining the samples. With this invention, the cigarette paper samples are placed outside the constant temperature and humidity chamber, eliminating the need to keep the chamber door open for extended periods, thus reducing abnormal temperature and humidity fluctuations and alarms within the equipment. Simultaneously, the evenly distributed clamping mechanisms and cigarette paper samples ensure sufficient contact between the samples and the regulating airflow, guaranteeing accurate test results.

For those skilled in the art, the specific meaning of the above-mentioned terms can be understood according to the specific circumstances.

[0021] like Figures 1-3 As shown, this utility model discloses a suspension device for a constant temperature and humidity chamber, installed inside the chamber. It includes a guide rail frame 1 and a suspension frame 2. The guide rail frame 1 includes symmetrically arranged grooved guide rails 11. A slider 21, which slides along the grooved guide rails 11, is fixedly mounted at the bottom of the suspension frame 2. Several supports 22 are symmetrically distributed on the suspension frame 2. For example, each support 22 is a hollow cylinder fixedly or slidably connected to a bottom support, and the slider 21 is fixedly connected to the bottom of the bottom support. Cantilever arms 23 are inserted into the corresponding supports 22 on both sides, and several clamping mechanisms 3 for holding cigarette paper samples are evenly distributed on the cantilever arms 23.

[0022] In this embodiment, the clamping mechanism 3 includes a fixed plate 31 and a movable plate 32. The middle part of the movable plate 32 is rotatably connected relative to the fixed plate 31, and a spring 33 is provided between the fixed plate 31 and the movable plate 32. The movable plate 32 is in a deformed Z-shape, and the contact surface between the movable plate 32 and the cigarette paper sample is planar. Meanwhile, the contact surfaces of the fixed plate 31 and the movable plate 32 with the cigarette paper sample are made of silicone material to ensure the stability of the paper sample clamping and to avoid damage to the paper sample.

[0023] In this embodiment, several stabilizing mechanisms 4 for stabilizing the cigarette paper sample are provided below the suspension frame 2. For example, the stabilizing mechanism 4 includes a fixed back plate 41 and a round strip 42 snapped onto the back plate 41. One end of the round strip 42 is hinged to the back plate 41 via a pin, and the other end of the round strip 42 is snapped into a holder at the other end of the back plate 41. After the clamping mechanism 3 clamps the strip-shaped cigarette paper sample, it is fixed to the stabilizing mechanism 4 by snapping it onto the round strip 42. The round strip 42 and the back plate 41 are used to clamp the paper sample. The contact area between the paper sample and the round strip 42 is small, allowing for some relative sliding, thereby preventing the cigarette paper sample from being completely stretched between the clamping mechanism 3 and the stabilizing mechanism 4, reducing the possibility of damage to the paper sample.

[0024] In this embodiment, in order to increase the processing capacity of cigarette paper samples, the guide rail frame 1 and the suspension frame 2 can be arranged in a multi-layer structure with the upper and lower parts arranged. The cantilever 23 between adjacent guide rail frames 1 can be staggered so that all the suspended cigarette paper samples can fully contact the bottom airflow of the constant temperature and humidity chamber.

[0025] In this embodiment, the cantilever 23 is U-shaped and includes two vertical rods inserted into the support 22 and a horizontal rod for installing the clamping mechanism 3. The U-shaped cantilever 23 is inserted upside down into the symmetrical support 22.

[0026] In this embodiment, to enhance the connection stability between the suspension bracket 2 and the guide rail bracket 1, the grooved guide rail 11 has a dovetail groove structure, and the corresponding slider 21 is also dovetail-shaped. After the slider 21 of the suspension bracket 2 slides into the grooved guide rail 11 with the dovetail groove structure, the suspension bracket 2 is constrained by the dovetail groove structure and will not wobble. After the four sliders 21 of the suspension bracket 2 slide out, because they are in the shape of an isosceles trapezoid, such as Figure 2 As shown, it can be placed stably on the platform, making it easy to operate, clamp, and secure the paper pattern.

[0027] In this embodiment, a reinforcing crossbeam is provided between the grooved guide rails 11, and a handle is provided on the outer side of the reinforcing crossbeam. The suspension bracket 2 can be slid in and out through the handle, making operation convenient.

[0028] The working principle of this utility model is as follows:

[0029] When using the suspension device of this utility model, the constant temperature and humidity chamber can be opened, the suspension frame 2 can be quickly slid out, the round bar 42 can be removed, and then the cigarette paper sample to be adjusted can be placed in by rotating the movable plate 32. The movable plate 32 can be released, and under the drive of the spring, the contact surface of the movable plate 32 abuts against the fixed plate, thus clamping the cigarette paper sample. This step is repeated to complete the clamping of the cigarette paper sample. After all the cantilever 23 has clamped the sample, the lower ends of all the cigarette paper samples are aligned with the back plate 41, and then the round bar 42 is engaged to stabilize the sample and prevent it from swinging with the airflow. After all the cantilever has clamped and stabilized the cigarette paper sample, the constant temperature and humidity chamber can be opened again, and the suspension frame 2 can be slid in for adjustment.

[0030] During this process, the cigarette paper sample is placed outside the constant temperature and humidity chamber, eliminating the need to keep the chamber door open for extended periods, thus reducing abnormal temperature and humidity fluctuations and alarms within the constant temperature and humidity equipment. Simultaneously, the clamping mechanisms 3 are evenly arranged, ensuring uniform distribution of the cigarette paper sample and maximizing contact between the sample and the regulated airflow, thereby guaranteeing the accuracy of the test results.

[0031] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
