Description

Technical Field

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

[0002] With the continuous changes in the cigarette consumption market environment, it is ultimately reflected in the consumer group's personalized demand for tobacco industry products. This requires tobacco products to constantly update themselves and launch new products of different specifications.

[0003] In the tobacco industry, physical parameters such as weight, circumference, length, roundness, and draw resistance must be tested during cigarette production to control production quality. Currently, cigarette length testing is often performed using a serration system, which is inconvenient, inefficient, and difficult to use when testing large quantities of cigarettes. Summary of the Invention

[0004] Based on the problems mentioned in the above background technology, the present invention provides a continuous detection device for standard length of cigarettes, which is used to solve the current problems of inconvenient operation, low detection efficiency and inconvenience in using when the detection volume is large when detecting cigarette length.

[0005] The technical solution adopted in the present invention is as follows:

[0006] A device for continuously detecting the standard length of cigarettes comprises a base, a detection seat is installed on the base, a detection platform is provided in the detection seat, a blanking trough is provided on the detection platform, the top of the blanking trough is provided with a chamfer, an arc-shaped placement piece is installed in the blanking trough of the detection platform, a rotating shaft is integrally formed at one end of the arc-shaped placement piece, a U-shaped groove with a semicircular bottom end is provided on the rotating shaft, the semicircular inner wall of the U-shaped groove is cocircular with the inner wall of the arc-shaped placement piece, a limiting groove is provided on the outer wall of the rotating shaft, a limiting seat is fixedly installed in the blanking trough, a clamping block corresponding to the limiting groove is provided on the limiting seat, an adjusting rod is installed on the rotating shaft, and a pre-set clamp matching the adjusting rod is provided on the detection seat. A slot is left, a material cabin is installed in the blanking chute, an avoidance observation slot is provided on the material cabin, a connecting seat is installed on the base, two first sliding rods are installed on the connecting seat, a blind hole is provided on the detection seat, the first sliding rod is passed through the blind hole, a first mounting seat is installed on the connecting seat, a pressure gauge is embedded in the first mounting seat, a first push head is installed on the pressure gauge, a second mounting seat is installed on the detection seat, a mounting tube is installed on the second mounting seat, a second sliding rod is passed through the mounting tube, a second push head is installed on the second sliding rod, a first spring is installed between the second push head and the second mounting seat, and the first spring is sleeved on the second sliding rod.

[0007] On the basis of the above technical solution, the present invention has also made the following improvements:

[0008] Furthermore, a support base is provided at the bottom end of the base, and a material guide trough is provided on the base. Cigarettes that fall after detection are naturally transferred through the material guide trough to prevent the cigarettes from piling up at the bottom of the base.

[0009] Furthermore, the detection base is provided with a through hole connected to the blind hole. A third slide bar is mounted on each of the first slide bars. The third slide bar is inserted into the through hole. A limit ring is mounted on the third slide bar. A second spring is sleeved on the third slide bar. The second spring is located in the blind hole. When the detection base is pushed to move, the detection base can automatically return to its original position under the action of the second spring, making it convenient for the next use.

[0010] Furthermore, a universal ball is installed at the bottom end of the detection seat, and a ball groove corresponding to the universal ball is opened on the base. The universal ball reduces the friction resistance between the base and the detection seat so that the detection seat can slide better.

[0011] Furthermore, the mounting tube is screwed onto the second mounting base. The position of the mounting tube is adjustable, which can change the initial compression of the first spring and calibrate the pressure gauge so that the pressure gauge value can be maintained at a standard value when detecting cigarettes of different lengths.

[0012] Furthermore, the arc-shaped placement piece is provided with a slope, and when the slope is coplanar with the chamfer, the adjustment rod contacts the bottom end of the reserved groove, thereby preventing the arc-shaped placement piece from blocking the drop chute due to the difficulty in controlling the rotation angle of the adjustment rod, making it difficult for cigarettes to fall into the drop chute smoothly.

[0013] Furthermore, a wide-mouth hopper is provided on the top of the cabin, which makes it easier to put cigarettes into the cabin and is convenient to use.

[0014] Beneficial effects of the present invention:

[0015] 1. Place the cigarette to be tested in the U-shaped placement slot, pull the test seat to slide, and the first pusher on the pressure gauge pushes the cigarette to move and contact the second pusher. Due to the restriction of the connecting seat, the maximum movable stroke of the test seat is constant. When the length of the cigarette does not meet the standard, the deformation of the first spring will change, that is, the pressure gauge reading will change. Based on the pressure gauge reading, it can be determined whether the length of the tested cigarette is standard. The operation is simple, easy to use, and the detection efficiency is high.

[0016] 2. By rotating the adjusting rod, the arc-shaped placement piece is driven to rotate and open the chute, so that the tested cigarettes can fall freely along the chute. At the same time, the rotated arc-shaped placement piece can block the material compartment to prevent the cigarettes in the material compartment from falling out when the chute is opened. After the arc-shaped placement piece is turned back to close the chute, the cigarettes in the material compartment will fall into the arc-shaped placement piece for testing. It is convenient to change materials and is more convenient to use when a large number of cigarettes need to be tested. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] 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.

[0030] Example

[0031] like Figures 1 to 9 As shown, a device for continuously detecting standard length of cigarettes comprises a base 1, a detection seat 2 is mounted on the base 1, a detection platform 21 is arranged in the detection seat 2, a blanking trough 211 is provided on the detection platform 21, a chamfer 212 is provided at the top of the blanking trough 211, an arc-shaped placement piece 41 is installed in the blanking trough 211 of the detection platform 21, a rotating shaft 42 is integrally formed at one end of the arc-shaped placement piece 41, a U-shaped groove 422 with a semicircular bottom end is provided on the rotating shaft 42, the semicircular inner wall of the U-shaped groove 422 is cocircular with the inner wall of the arc-shaped placement piece 41, a limiting groove 421 is provided on the outer wall of the rotating shaft 42, a limiting seat 43 is fixedly installed in the blanking trough 211, a clamping block 431 corresponding to the limiting groove 421 is provided on the limiting seat 43, an adjusting rod 44 is mounted on the rotating shaft 42, and a clamping block 431 corresponding to the limiting groove 421 is provided on the detection seat 2. 44 matching reserved slots 24, a material cabin 23 is installed in the blanking trough 211, an avoidance observation slot 232 is provided on the material cabin 23, a connecting seat 11 is installed on the base 1, two first slide bars 12 are installed on the connecting seat 11, a blind hole is provided on the detection seat 2, the first slide bar 12 is passed through the blind hole, a first mounting seat 15 is installed on the connecting seat 11, a pressure gauge 16 is embedded in the first mounting seat 15, a first pusher head 17 is installed on the pressure gauge 16, a second mounting seat 31 is installed on the detection seat 2, a mounting tube 32 is installed on the second mounting seat 31, a second slide bar 33 is passed through the mounting tube 32, a second pusher head 35 is installed on the second slide bar 33, a first spring 34 is installed between the second pusher head 35 and the second mounting seat 31, and the first spring 34 is sleeved on the second slide bar 33.

[0032] Specifically, a support base 18 is provided at the bottom end of the base 1, and a guide trough 19 is provided on the base 1. The cigarettes 5 that fall after detection naturally roll down and transfer through the guide trough 19, preventing the cigarettes 5 from piling up at the bottom of the base 1.

[0033] Specifically, the detection base 2 is provided with a through hole connected to the blind hole. A third slide bar 13 is mounted on each first slide bar 12. The third slide bar 13 is inserted into the through hole. A limit ring 131 is mounted on the third slide bar 13. A second spring 14 is sleeved on the third slide bar 13 and located in the blind hole. When the detection base 2 is pushed by the second spring 14, it can return to its original position, making it convenient for the next use.

[0034] Specifically, a universal ball is installed at the bottom end of the detection base 2, and a ball groove corresponding to the universal ball is opened on the base 1. The universal ball reduces the friction resistance between the base 1 and the detection base 2 so that the detection base 2 can slide better.

[0035] Specifically, the mounting tube 32 is screwed onto the second mounting base 31. The position of the mounting tube 32 is adjustable, which can change the initial compression of the first spring 34 and calibrate the pressure gauge 16 so that the value of the pressure gauge 16 can be maintained at the standard value when detecting cigarettes of different lengths.

[0036] Specifically, the curved placement piece 41 is provided with a slope 411. When the slope 411 is coplanar with the chamfer 212, the adjustment rod 44 contacts the bottom end of the reserved groove 24. This prevents the adjustment rod 44 from rotating at an angle that is difficult to control, causing the curved placement piece 41 to block the drop chute 211, making it difficult for the cigarette 5 to fall smoothly into the drop chute 211.

[0037] Specifically, a wide-mouth hopper 23 is provided at the top of the material cabin 23. The design of the wide-mouth hopper 23 makes it easier to put cigarettes 5 into the material cabin 23, which is convenient for use.

[0038] During the test, the cigarettes to be tested are placed in the material chamber 23, and the cigarettes in the material chamber 23 fall into the arc-shaped placement piece 41 by themselves. When testing is required, the detection seat 2 is pulled to slide until the detection seat 2 contacts the connecting seat 11. During the sliding of the detection seat 2, the first pusher 17 on the pressure gauge 16 pushes the cigarette 5 to move and contact the second pusher 35. Due to the limitation of the connecting seat 11, the maximum movable stroke of the detection seat 2 is constant. When the length of the cigarette 5 does not meet the standard, the deformation of the first spring 34 will change, that is, the reading of the pressure gauge 16 will change. Changes occur, and the reading of the pressure gauge 16 can be used to determine whether the length of the tested cigarette 5 is standard; after the test is completed, the adjusting rod 44 is rotated to drive the arc-shaped placement piece 41 to rotate and open the drop chute 211, so that the tested cigarette 5 can fall freely along the drop chute 211. At the same time, the rotated arc-shaped placement piece 41 can block the material chamber 23 to prevent the cigarettes 5 in the material chamber 23 from falling out when the drop chute 211 is opened. After the arc-shaped placement piece 41 is turned back to close the drop chute 211, the cigarettes 5 in the material chamber 23 fall into the arc-shaped placement piece 41 by themselves to continue testing.

[0039] When making a judgment, a plurality of cigarettes of standard length are first selected for testing, and the average value of the pressure gauge 16 reading is recorded as the standard value. When the pressure gauge 16 reading is greater than the standard value during the test, it indicates that the first spring 34 has contracted excessively, and the length of the currently tested cigarette 5 is greater than the standard length. Otherwise, it indicates that the length of the cigarette 5 is less than the standard length. The operation is simple, the use is convenient, and the detection efficiency is high.

[0040] The above describes in detail the device for continuously detecting the standard length of cigarettes provided by the present invention. The description of the specific embodiments is intended only to facilitate understanding of the method and core concepts of the present invention. It should be noted that those skilled in the art will appreciate that various improvements and modifications may be made to the present invention without departing from the principles of the present invention, and such improvements and modifications fall within the scope of protection of the claims.
