Description

Technical Field

[0001] This invention relates to the field of measurement technology, specifically to a device for measuring the hardness of cigarettes and its usage. Background Technology

[0002] The final step in the production of cigarette sticks and filter rods is to measure hardness. According to the Chinese tobacco industry standard, hardness is defined as the percentage of the radial diameter of the sample after being compressed to the diameter of the sample before being compressed within a certain period of time. It is specified that there are two stages: pre-compression and compression. The compression weight in the pre-compression stage is 10 to 20 grams, and the compression weight is 299 to 301 grams.

[0003] A search revealed Chinese Patent Publication No. CN206945428U, published on January 30, 2018, which discloses a cigarette hardness measuring device. The device includes a linear drive mechanism whose direction of motion is perpendicular to a pressure sensor. A pressure head, driven by the linear drive mechanism and facing the pressure sensor, is mounted on the linear drive mechanism. However, this method requires manual placement of the cigarette precisely into the working area. This is cumbersome due to the need for repeated manual operations such as releasing the cigarette and activating the linear drive mechanism. Furthermore, it cannot guarantee the uniformity of the cigarette's position each time it is released, leading to significant fluctuations in the measurement results. Therefore, this case was developed to address these issues through in-depth research. Summary of the Invention

[0004] The purpose of this invention is to provide a cigarette hardness measuring device and a method of using it, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A cigarette hardness measuring device includes a base, a conveyor belt, and a testing mechanism;

[0007] The upper surface of the base is provided with an arc groove for receiving cigarettes, and the detection mechanism is located directly above the arc groove. The base is also provided with an embedding groove for embedding the conveyor belt.

[0008] The conveyor belt is installed in the bottom shell, one end of which extends out of the base and the other end is located in the embedding groove. The conveyor belt is provided with partitions at intervals and is inclined.

[0009] The detection mechanism includes a pressing plate, a protective pad, and a pressure sensor. The pressing plate is located directly above the arc groove and moves up and down. A pressure sensor is embedded in the bottom surface of the pressing plate, and a protective pad is provided on the bottom surface of the pressing plate.

[0010] Furthermore, it also includes a fixing frame, which is set on the base and has a glass cover. The glass cover has a display and a discharge port, wherein the discharge port is located on the side of the arc groove.

[0011] Furthermore, a slanted stop block is also provided in front, and the slanted stop block is located on the front side of the arc groove.

[0012] Furthermore, it also includes a cylinder, which is vertically mounted on a fixed frame, with the cylinder's ejection end pointing towards the base and a pressing plate provided at the cylinder's ejection end.

[0013] Furthermore, an analog-to-digital converter is provided on the mounting bracket, the pressure sensor is electrically connected to the analog-to-digital converter, and the analog-to-digital converter is electrically connected to the display.

[0014] Furthermore, a photoelectric switch for controlling the operation of the cylinder is embedded in the bottom surface of the arc groove.

[0015] Based on the above-mentioned measuring device, its usage method is as follows: place the cigarette at the end of the conveyor belt, and transport the cigarette to the glass cover through the partition of the conveyor belt. When it is transported to the end of the conveyor belt, the partition enters the embedding groove and can no longer block the cigarette, causing the cigarette to roll into the arc groove. When the photoelectric switch receives the signal of the arrival of the cigarette, it starts the cylinder. At the same time, the protective pad presses down on the cigarette, and the pressure sensor detects the pressure signal and converts it into a digital signal through the analog-to-digital converter, which is displayed on the display. After the detection is completed, the cigarette is taken out from the discharge port.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This application includes a conveyor belt and partitions, and an arc groove in front of the base. The user places the cigarettes on the outside of the conveyor belt, and the cigarettes are conveyed forward by the rotation of the partitions, which replaces the manual feeding method and greatly improves the detection efficiency. The conveyor belt is inclined and the arc groove is provided on the base so that the cigarettes can roll into the arc groove, thereby ensuring the uniformity of the cigarette position during each detection and reducing detection fluctuations.

[0018] During testing, a cylinder drives a pressing plate to press the cigarettes in the processing tank, while a protective pad protects the cigarettes. During this process, a pressure sensor detects the hardness of the cigarette and displays the results on a screen, making the testing process more convenient and simple. Attached Figure Description

[0026] refer to Figure 1-3 As shown, this application provides a cigarette hardness measuring device, including a base 1, a conveyor belt 402, and a detection mechanism;

[0027] The upper surface of the base 1 is provided with an arc groove 406 for receiving the cigarette 5. The arc of the arc groove 406 is an arc surface with an arc of 1 / 4 to 1 / 2. The detection mechanism is located directly above the arc groove 406. The base 1 is also provided with an embedding groove for embedding the conveyor belt 402.

[0028] The conveyor belt 402 is disposed in the bottom shell 404. The two side walls of the bottom shell 404 are slightly higher than the conveying surface of the conveyor belt 402. One end of the bottom shell 404 extends out of the base 1. Preferably, a hopper structure is provided at this end, which allows the cigarettes 5 in the hopper to fall onto one end of the conveyor belt 402. The other end of the bottom shell 404 is located in the embedding groove. The conveyor belt 402 is provided with partitions 403 at intervals and the conveyor belt 402 is inclined. The partitions 403 at the end of the conveyor belt 402 need to be located in the embedding groove, so that the partitions 403 of the conveyor belt 402 can transport the cigarettes 5 one by one in an orderly manner. When the cigarettes 5 are transported to the end, they can be unloaded and rolled into the arc groove 406. Preferably, the conveyor belt 402 is driven by a stepper motor.

[0029] The detection mechanism includes a pressing plate 409, a protective pad 408, and a pressure sensor 410. The pressing plate 409 is located directly above the arc groove 406 and moves up and down. The pressure sensor 410 is embedded in the bottom surface of the pressing plate 409, and the protective pad 408 is set on the bottom surface of the pressing plate 409. The protective pad 408 is made of rubber and can be attached to the bottom surface of the pressing plate 409 by adhesive.

[0030] The device also includes a fixing frame 2, which is mounted on the base 1 and has a glass cover 3. Preferably, there are two glass covers 3 located at the front and rear of the fixing frame 2. The glass cover 3 located at the front is hinged. A display 412 and a discharge port 6 are mounted on the glass cover 3. The discharge port 6 is located on the side of the arc groove 406, and the size of the discharge port 6 must be larger than the size of the cigarette 5.

[0031] In some embodiments, a smoke-pushing mechanism may be provided on another glass cover 3, located on the opposite side of the discharge port 6. Preferably, the smoke-pushing mechanism adopts an air-blowing method, and its specific structure can be set with reference to the prior art, so as to blow the cigarette 5 out from the discharge port 6.

[0032] In order to obtain the hardness data of cigarette 5, an analog-to-digital converter 413 is provided on the fixing frame 2. The pressure sensor 410 is electrically connected to the analog-to-digital converter 413, and the analog-to-digital converter 413 is electrically connected to the display 412, so that the detection data can be displayed on the display 412.

[0033] In some embodiments, an inclined block 407 is also provided in front of the circular arc groove 406, which can further ensure that the cigarette 5 can fall into the circular arc groove 406.

[0034] To achieve the lifting and lowering movement of the pressing plate 409, a cylinder 411 is also included. Preferably, the cylinder 411 is a mini cylinder with a short stroke. The cylinder 411 is vertically mounted on the fixed frame 2, with the extension end of the cylinder 411 pointing towards the base 1 and the pressing plate 409 is provided at the extension end of the cylinder 411. It should be noted that after the cylinder 411 pushes the pressing plate 409 down to the bottom, it maintains a time of 0.5-1 seconds before resetting, thereby ensuring the continuity of detection. Furthermore, a photoelectric switch 401 for controlling the operation of the cylinder 411 is embedded in the bottom surface of the arc groove 406. When the cigarette 5 falls into the arc groove 406, the photoelectric switch 401 detects the arrival of the cigarette 5 and activates the cylinder 411.

[0035] Based on the above-described cigarette hardness measuring device, its usage method is as follows: Place the cigarette 5 at the end of the conveyor belt 402 (or, if a hopper is provided, load the cigarette 5 into the hopper). The cigarette 5 is conveyed to the glass cover 3 via the partition 403 of the conveyor belt 402. When the cigarette 5 reaches the end of the conveyor belt 402, the partition 403 enters the embedding groove and can no longer block it, causing the cigarette to roll into the arc groove 406. When the photoelectric switch 401 receives the signal of the arrival of the cigarette 5, it activates the cylinder 411. Simultaneously, the protective pad 408 presses down on the cigarette 5, and the pressure sensor 410 detects the pressure signal and converts it into a digital signal via the analog-to-digital converter 413, which is then displayed on the display 412. After the detection is completed, the cigarette 5 is removed from the discharge port 6.

[0036] Although the invention has been described herein with reference to several illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various modifications and improvements can be made to the components or layout of the subject matter arrangement within the scope of the disclosure, drawings, and claims. Besides modifications and improvements to the components or layout, other uses will be apparent to those skilled in the art.
