Description

Technical Field

[0001] This invention belongs to the field of cigarette production and testing technology, specifically relating to a detector for the outer diameter qualification of cigarettes. Background Technology

[0002] In the tobacco industry, the cigarette production process requires the testing of physical parameters such as weight, circumference, length, roundness, and draw resistance to control cigarette quality. The QTM integrated testing platform, designed by the British company CERULEAN, is used to test these physical parameters. Currently, when testing whether the outer diameter of a cigarette meets the standard, the method often involves inserting the cigarette into a hole in a testing mold and judging the outer diameter based on the resistance between the cigarette and the hole. This method is inefficient and relies heavily on the experience of the staff, leading to significant errors. Summary of the Invention

[0003] In view of the problems mentioned in the background art above, the present invention provides a qualified detector for the outer diameter of cigarettes, which solves the problems of low detection efficiency, the need for differentiation based on experience, and large detection error when detecting the outer diameter of cigarettes.

[0004] The technical solution adopted in this invention is as follows:

[0005] A detector for the outer diameter of cigarettes includes a base with a top cover hinged to it, a base plate on the base, a first semicircular groove on the base plate, an upper seat on the top cover, and a second semicircular groove corresponding to the first semicircular groove on the upper seat. A test tube is disposed in the first semicircular groove. Two blind holes are provided on the base, and a first sliding rod passes through each of the two blind holes. A connecting frame is mounted on the first sliding rod, and a first mounting seat is mounted on the connecting frame. A pressure gauge is embedded in the first mounting seat, and a first push plate is mounted on the pressure gauge. The first push plate is coaxial with the test tube.

[0006] Based on the above technical solution, the present invention has made the following improvements:

[0007] Furthermore, the test tube is aligned with the axis of the first semicircular groove, and the end of the test tube is chamfered. This makes it easier to push the cigarette placed in the first semicircular groove into the test tube, facilitating use and improving testing efficiency.

[0008] Furthermore, the base has a through hole communicating with the blind hole. A second slide rod is installed on each of the first slide rods, passing through the through hole. A limit ring is installed on each second slide rod, and a first spring is sleeved on each second slide rod, with the first spring located within the blind hole. Under the action of the first spring, after the first slide rod slides and pushes the cigarette to move, it can automatically return to its original position for convenient use.

[0009] Furthermore, the connecting frame has a threaded hole, and an adjusting screw is screwed into the threaded hole. By rotating the adjusting screw to adjust the length of the adjusting screw between the mounting frame and the base, the movement stroke of the mounting frame can be adjusted, thereby controlling the depth to which the cigarette can be pushed into the test tube.

[0010] Furthermore, a second mounting base is provided on the base, and a top rod passes through the second mounting base. A top post and a second push plate are respectively mounted at both ends of the top rod. A second spring is installed between the second push plate and the second mounting base, located between the second mounting base and the second push plate. The top post is coaxial with the test tube, and the outer diameter of the top post is smaller than the inner diameter of the test tube. Under the action of the top rod and the top post, the top rod can be moved after the test to push the cigarette out of the test tube through the top post, facilitating use.

[0011] Furthermore, a pull block is installed on the upper cover. The pull block facilitates the opening and closing of the upper cover.

[0012] Furthermore, a fixed wing is installed on the base. The fixed wing facilitates the movement of the first mounting base.

[0013] Furthermore, a rubber pad is fixedly bonded to the bottom of the base. The rubber pad increases the frictional resistance at the bottom of the base, preventing the base from sliding and affecting use when the detector is placed on a table.

[0014] The beneficial effects of this invention are:

[0015] By placing the cigarette to be tested into the first semicircular groove, and then lowering the top cover, the first and second semicircular grooves form a complete through hole to guide the cigarette. The second mounting base moves and pushes the cigarette into the test tube via the first push plate. The frictional resistance between the cigarette and the test tube can be detected by a pressure gauge. The magnitude of the frictional resistance determines whether the outer diameter of the cigarette meets the standard. It is easy to use, has high testing efficiency, does not require the judgment of the staff based on experience, and has high testing accuracy. Attached Figure Description

Detailed Implementation

[0023] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] Example

[0025] like Figures 1-4 As shown, a cigarette outer diameter conformity detector includes a base 1, a fixed wing 17 mounted on the base 1, and a top cover 2 hinged to the base 1. To facilitate the opening and closing of the top cover 2, a pull block 23 is mounted on the top cover 2. A rubber pad is fixedly adhered to the bottom end of the base 1 to increase the frictional resistance at the bottom end of the base 1, preventing the base 1 from sliding and affecting use when the detector is placed on a table. A base 11 is provided on the base 1, and a first semi-circular groove 12 is formed on the base 11. The top cover 2 has an upper... The upper seat 21 has a second semicircular groove 22 corresponding to the first semicircular groove 11. The first semicircular groove 12 contains a test tube 13. The base 1 has two blind holes 16. A first slide rod 31 passes through each of the two blind holes 16. A connecting frame 32 is installed on the first slide rod 31. A first mounting seat 34 is installed on the connecting frame 32. A pressure gauge 35 is embedded in the first mounting seat 34. A first push plate 36 is installed on the pressure gauge 35. The first push plate 36 is coaxial with the test tube 13.

[0026] Specifically, the test tube 13 is aligned with the axis of the first semicircular groove 12, and the end of the test tube 13 is chamfered 131. When the cigarette 4 is placed in the first semicircular groove 12, it is easier to push the cigarette 4 into the test tube 13, which is convenient to use and helps to improve the detection efficiency.

[0027] Specifically, the base 1 has a through hole that communicates with the blind hole 16. A second slide rod 37 is installed on each of the first slide rods 31. The second slide rod 37 passes through the through hole and is fitted with a limit ring 371. A first spring 38 is sleeved on the second slide rod 37. The first spring 38 is located in the blind hole 16. Under the action of the first spring 38, when the first slide rod 31 slides and pushes the cigarette 4 to move, it can return to its original position by itself, which is convenient for use.

[0028] Specifically, the connecting frame 32 has a threaded hole, and an adjusting screw 33 is screwed into the threaded hole. When it is necessary to adjust the depth to which the cigarette 4 can be pushed into the test tube 13, the length of the adjusting screw 33 between the mounting frame 32 and the base 1 can be adjusted by rotating the adjusting screw 33, thereby adjusting the travel of the mounting frame 33.

[0029] Specifically, a second mounting base 14 is provided on the base 1, and a top rod 15 is passed through the second mounting base 14. A top column 151 and a second push plate 152 are respectively installed at both ends of the top rod 15. A second spring 153 is installed between the second push plate 152 and the second mounting base 14. The second spring 153 is located between the second mounting base 14 and the second push plate 152. The top column 151 is coaxial with the test tube 13, and the outer diameter of the top column 151 is smaller than the inner diameter of the test tube 13. After the test is completed, the top rod 15 is moved to push out the cigarette 4 in the test tube 13 through the top column 151 for easy use.

[0030] During testing, the top cover 2 is lifted by the pull block 23, and the cigarette 4 to be tested is placed into the first semicircular groove 12. Then, the top cover 2 is lowered so that the first semicircular groove 12 and the second semicircular groove 22 form a complete through hole to guide the cigarette 4. Then, the second mounting base 34 is pushed to move, which drives the pressure gauge 35 to move. Under the action of the first push plate 36, the cigarette 4 is pushed into the test tube 13. The frictional resistance between the cigarette 4 and the test tube 13 can be detected by the pressure gauge 35. The magnitude of the frictional resistance determines whether the outer diameter of the cigarette 4 meets the standard. When determining whether it meets the standard, multiple standard cigarettes are first tested and their average value is taken as the reference standard. When judging, if the reading of the pressure gauge 35 is greater than the standard value, it means that the diameter of the cigarette 4 is greater than the standard size. When judging, if the reading of the pressure gauge 35 is less than the standard value, it means that the diameter of the cigarette 4 is less than the standard size. The detection efficiency is high, and there is no need to rely on the experience of the staff for judgment. The detection accuracy is high.
