Description

Technical Field

[0001] The invention belongs to the technical field of cigarette production detection, and in particular relates to a device for detecting the qualified length of cigarettes. Background Art

[0002] In the tobacco industry, physical parameters such as weight, circumference, length, roundness, and draw resistance of cigarettes must be tested during the cigarette production process to control production quality. The QTM integrated test bench, designed by the British company CERULEAN, is used to test physical parameters such as weight, circumference, length, roundness, and draw resistance of cigarettes. During testing, samples are taken from the cigarette forming machine conveyor belt and placed on the QTM integrated test bench for testing of various physical parameters. Circumference and length are key parameters for cigarette testing, and samples are taken and tested on the integrated test bench every hour during production. However, the testing process is complex, requiring cigarettes to be brought to the test bench for testing, resulting in low efficiency and inconvenience. Summary of the Invention

[0003] Based on the problems mentioned in the above background technology, the present invention provides a cigarette qualified length detection device, which is used to solve the problem that the current procedure for detecting the length of cigarettes is relatively complicated, the cigarettes need to be taken to the detection table for detection, the detection efficiency is low, and it is inconvenient to use.

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

[0005] The cam is provided with a toothed structure, and the toothed structure is provided with a toothed structure, and the toothed structure is provided with a toothed structure, and the toothed structure is provided with a toothed structure.

[0006] Furthermore, an arc-shaped guide plate is integrally formed at the end of the pressing sheet, which can directly press the cigarette downward when the pressing sheet moves and contacts the cigarette, thereby effectively preventing the arc-shaped guide plate from laterally squeezing the cigarette and damaging the cigarette structure.

[0007] Furthermore, a reinforcing plate is integrally formed on the top of the pressing plate and welded to the pull rod to enhance the strength of the pressing plate and prevent deformation of the pressing plate that would cause changes in the testing standards.

[0008] Furthermore, a positioning slider is integrally formed on the outer wall of the connection frame, and a positioning plate is fixedly mounted on the outer wall of the detection tube. The positioning plate has a slot corresponding to the positioning slider. The positioning slider and the positioning plate can limit the connection frame, preventing the connection frame from tilting, which could cause the pressing plate to misalign with the avoidance groove and affect its use.

[0009] Furthermore, a feed hopper is integrally formed on the top of the detection tube, so that cigarettes to be tested can be better placed into the detection tube through the feed hopper.

[0010] Furthermore, an elastic band is installed on the outer wall of the detection tube, so that the length detection device can be hung on the body for use at any time.

[0011] Beneficial effects of the present invention:

[0012] Place the cigarette in the detection tube, then move the pull rod to drive the carrier and the pressing plate to move. The carrier leaves the lower end of the cigarette to make the cigarette contact with the contact plate. When the length of the cigarette exceeds the standard, the pressing plate contacts the top of the cigarette and presses the cigarette downward. The firing pin contacts the touch switch alarm and the alarm is triggered. It is easy to use and can quickly detect whether the length of the cigarette exceeds the standard, so that the production line can be adjusted in time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0022] Example

[0023] like Figures 1 to 5 As shown, a device for detecting the qualified length of cigarettes includes a detection tube 1, which is provided with two avoidance grooves 11 arranged opposite to each other, a base 36 is installed at the bottom end of the detection tube 1, a guide column 37 is installed on the detection tube 1, a pull rod 3 is slidably passed through the guide column 37, a limit ring 371 is installed at the end of the pull rod 3, a first spring 38 is provided between the pull rod 3 and the detection tube 1, the first spring 38 is sleeved on the guide column 37, a connecting frame 34 is fixedly installed on the pull rod 3, a carrier 35 is installed on the connecting frame 34, and a carrier 35 is located in the avoidance groove 11, and a pressing piece 31 is installed on the pull rod 3. The position of the pressing piece 31 corresponds to the avoidance groove 11. A mounting plate 51 is fixed to the bottom end of the detection tube 1, and a sleeve 52 is provided on the mounting plate 51. A striker 54 is slidably passed through the sleeve 52, and a contact plate 53 is installed on the top of the striker 54. A second spring 55 is installed between the contact plate 53 and the mounting plate 51. The second spring 55 is sleeved on the sleeve 52. An alarm 56 is installed on the mounting plate 51, and a touch switch 57 is provided on the top of the alarm 56.

[0024] Specifically, an arc-shaped guide plate 32 is integrally formed at the end of the pressing sheet 31. The arc-shaped guide plate 32 allows the pressing sheet 31 to move and contact the cigarette 6 to directly press the cigarette 6 downward, which can better prevent the arc-shaped guide plate 32 from laterally squeezing the cigarette 6 and avoiding damaging the structure of the cigarette 6.

[0025] Specifically, a reinforcing plate 33 is integrally formed at the top of the pressing piece 31 and welded to the pull rod 3 . The reinforcing plate 33 enhances the strength of the pressing piece 31 and prevents the pressing piece 31 from being deformed, which would cause changes in the inspection standard.

[0026] Specifically, a positioning slider 341 is integrally formed on the outer wall of the connecting frame 34, and a positioning plate 41 is fixedly installed on the outer wall of the detection tube 1. A sliding groove 42 corresponding to the positioning slider 341 is provided on the positioning plate 41. The connecting frame 34 can be limited by the restriction of the positioning slider 341 and the positioning plate 41 to prevent the connecting frame 34 from being deflected and causing the pressing piece 31 and the avoidance groove 11 to be misaligned, thereby affecting use.

[0027] Specifically, a feed hopper 2 is integrally formed at the top of the detection tube 1 , and the cigarettes 6 to be tested can be better placed into the detection tube 1 through the feed hopper 2 .

[0028] Specifically, an elastic band 12 is installed on the outer wall of the detection tube 1, and the length detection device can be hung on the body through the elastic band 12 for easy use at any time.

[0029] During the test, the cigarette 6 is placed into the detection tube 1 through the feed hopper 2, with the filter end of the cigarette 6 facing upward. The detection tube 1 is held and the pull rod 3 is pulled by the fingers to drive the carrier 35 and the pressing plate 31 to move. The carrier 35 leaves the lower end of the cigarette 6 so that the cigarette 6 contacts the contact plate 53. At the same time, the pressing plate 31 gradually approaches the filter end of the cigarette 6 until the pressing plate 31 slides to the top of the cigarette 6. When the length of the cigarette 6 exceeds the standard, the pressing plate 31 contacts the top of the cigarette 6 and presses the cigarette 6 downward. The contact plate 53 presses the striker 54 to move downward to contact the touch switch 57, and the alarm 56 is triggered. It is easy to use. Whether the length of the cigarette 6 exceeds the standard can be judged by whether the alarm is triggered. Whether the length of the cigarette 6 exceeds the standard can be quickly detected, so that the production line can be adjusted in time.
