Description

Technical Field

[0001] The utility model relates to the technical field of determination of tobacco filling value, and specifically, it relates to a single-cup barrel tobacco filling value determination system. Background Art

[0002] The quality of tobacco shreds has a great influence on the sensory quality of cigarettes and also has a great influence on the effective operation rate of cigarette making and tipping equipment; the filling ability of tobacco shreds and the loss in the tobacco processing process basically determine the tobacco consumption per case of cigarettes, and even affect the consumption of other materials. As an important index for quality control in the cigarette making process, the tobacco filling value has received extensive attention and emphasis in the industry. Therefore, tobacco filling value measuring instruments have been widely used, providing a scientific detection means for quality control in the cigarette making production of the industry.

[0003] A tobacco filling value measuring instrument is a special detection instrument dedicated to detecting the filling ability of cigarette tobacco shreds (including cut tobacco, expanded cut tobacco, reconstituted tobacco shreds, etc.) and expanded stem shreds. The implementation standards of the tobacco filling value measuring instrument are YC / T 152-2001 "Determination of Tobacco Filling Value of Cigarettes", YC / T 163-2003 "Determination of Filling Value of Expanded Stem Shreds", JJG (Tobacco) 25-2010 "Verification Regulation of Tobacco Filling Value Measuring Instrument" and JJG (Tobacco) 26-2010 "Verification Regulation of Expanded Stem Shreds Filling Value Measuring Instrument".

[0004] When the existing tobacco filling value measuring instruments on the market are used for detection, it is necessary to manually put materials into the measuring barrel, then place the measuring barrel at the detection position for detection. After the detection is completed, the measuring barrel is manually cleaned, and then, materials are manually put in again for the next filling value detection. Such repeated operations result in high labor intensity, high labor cost and low detection efficiency.

[0045] The tobacco shreds weighing and transferring assembly is arranged on one side of the reference base plate 1 and is used to weigh a fixed amount of tobacco shreds and pour the weighed fixed amount of tobacco shreds into the hopper assembly.

[0046] The cup-barrel assembly includes a cup body 3. The cup body 3 is open at both the top and the bottom.

The rotatable plunger 9 plays a role in positioning and restricting the cup body 3.

[0048] In this embodiment, the feeding station, the measuring station, and the cleaning station are arranged at intervals from right to left.

A flange sleeve 14 is fixedly installed in the first mounting hole, and the lower end of the feeding hopper 12 is fixedly installed in the flange sleeve 14. The weighed tobacco shreds can be filled into the cup body 3 that moves to the feeding station through the feeding hopper 12.

[0050] The measuring assembly includes a second vertical plate 15, a second linear module 16, a pressing head 17, a guiding optical axis 18, a counterweight 19, a lifting bracket 20, and a magnetic scale reading head 21. The second vertical plate 15 is arranged at the rear side of the measuring station and fixedly installed on the reference base plate 1. The second linear module 16 is vertically and fixedly installed on the rear side surface of the second vertical plate 15. The pressing head 17 is arranged directly above the measuring station, and the outer diameter of the pressing head 17 ≤ the inner diameter of the cup body 3. A linear bearing 22 located directly above the pressing head 17 is fixedly installed on the lower side of the middle part of the front side surface of the second vertical plate 15. The guiding optical axis 18 is slidably installed through the linear bearing 22. The pressing head 17 is fixedly installed at the lower end of the guiding optical axis 18. A bracket structure 23 is fixedly installed at the upper end of the guiding optical axis 18. The counterweight 19 is placed on the bracket structure 23. A guiding long hole 24 is vertically formed in the second vertical plate 15 on one side of the second linear module 16 and above the linear bearing 22. The second linear module 16 drives the lifting bracket 20 to move up and down in the guiding long hole 24. The bracket structure 23 is supported on the lifting bracket 20. The length of the guiding optical axis 18 > the length of the guiding long hole 24 > the distance from the upper end of the linear bearing 22 to the lower end of the cup body 3. The magnetic scale reading head 21 is fixedly installed on the front side surface of the second vertical plate 15 and on one side of the guiding long hole 24. A magnetic strip block 25 arranged vertically and adapted to be in sliding contact with the magnetic scale reading head 21 is fixedly installed on the bracket structure 23. The magnetic scale reading head 21 and the magnetic strip block 25 form a magnetic scale.

[0051] The bracket structure 23 includes a support arm, an upper end plate, and a positioning pin. The support arm and the upper end plate are arranged on the upper end of the guiding optical axis 18 from bottom to top. The rod portion of the positioning pin passes through the support arm and the upper end plate from top to bottom and is fixedly connected to the upper end of the guiding optical axis 18. The head of the positioning pin presses tightly against the upper surface of the upper end plate, thereby fixing the support arm and the upper end plate to the upper end of the guiding optical axis 18. The support arm is supported on the lifting bracket 20. The magnetic strip block 25 is fixedly installed on the support arm. The counterweight is placed on the upper end plate.

[0052] The second linear module 16 in this embodiment is a ball screw type linear module. In other embodiments, the second linear module 16 can also be a synchronous belt type linear module or a linear motor type linear module, or other linear reciprocating motion mechanisms.

[0053] The working principle of the measuring component in this embodiment is as follows. Before the cup body 3 filled with a fixed amount of tobacco moves to the measuring station, the lifting bracket 20 raises the bracket structure 23 to the higher side of the guiding long hole 24, and the pressing head 17 is at a certain distance above the cup body 3. When the cup body 3 filled with a fixed amount of tobacco moves to the measuring station, the slider of the second linear module 16 drives the lifting bracket 20 to move down to the lower side of the guiding long hole 24. Then, the pressing head 17 falls downward into the cup body 3 under its own weight and presses on the tobacco. The lifting bracket 20 is separated from the bracket structure 23, and the guiding optical axis 18 can slide downward along the linear bearing 22. The weights of the counterweight 19 and the pressing head 17 are completely pressed on the tobacco in the cup body 3. The magnetic strip block 25 moves downward together with the bracket structure 23 and the downward displacement distance of the pressing head 17 after pressing on the tobacco for a certain time is detected by the magnetic grating head 21, and thus the filling value of the tobacco can be measured. After that, the slider of the second linear module 16 drives the lifting bracket 20 to reset and move upward to the higher side of the guiding long hole 24. The lifting bracket 20 raises the bracket structure 23 to move upward, so that the guiding optical axis 18 drives the pressing head 17 to be lifted upward, and the pressing head 17 is lifted out of the cup body 3 and away from the cup body 3, waiting for the next measurement of the tobacco filling value.

[0054] The material cleaning component includes a third vertical plate 26 and an electric push rod 27. The third vertical plate 26 is arranged at the rear side of the material cleaning station and fixedly installed on the reference bottom plate 1. A second mounting plate 28 which is located directly above the material cleaning station and higher than the cup body 3 is fixedly installed at the lower side of the middle part of the front side of the third vertical plate 26. The electric push rod 27 is arranged vertically, and the lower end of its cylinder body is fixedly installed on the second mounting plate 28. A through hole corresponding to the blanking hole 37 up and down is opened on the second mounting plate 28. The piston rod of the electric push rod 27 extends out from the lower end of the cylinder body and passes through the through hole. A brush head 29 is fixedly installed at the lower end of the piston rod of the electric push rod 27, and the outer diameter of the brush head 29 is the same as the inner diameter of the cup body 3. When the tobacco in the cup body 3 moves to the material cleaning station after the filling value is measured along with the cup body 3, the piston rod of the electric push rod 27 extends downward, so that the brush head 29 extends into the lower cup body 3, directly pushes out the tobacco in the cup body 3 downward, and makes the tobacco directly fall into the lower recovery bin 2 through the blanking hole 37. At the same time, the brush head 29 cleans the inner wall of the cup body 3. After that, the piston rod of the electric push rod 27 contracts upward to reset and withdraws the brush head 29 from the cup body 3. The empty cup body 3 after cleaning will move to the feeding station under the drive of the first linear module 7 to refill the fixed amount of tobacco weighed and transferred by the tobacco weighing and transferring component.

[0055] The first linear module 7 is fixedly installed at the lower side of the front side parts of the first vertical plate 11, the second vertical plate 15 and the third vertical plate 26 in the left - right direction.

[0056] For aesthetics, a protective shell 36 is provided at the rear sides of the first vertical plate 11, the second vertical plate 15, and the third vertical plate 26. The protective shell 36 is fixedly installed on the reference base plate 1. The front side and the lower side of the protective shell 36 are both open. The front end of the protective shell 36 is fixed and covers the rear side surfaces of the first vertical plate 11, the second vertical plate 15, and the third vertical plate 26.

[0057] In other embodiments, the feeding station, the measuring station, and the material cleaning station may also be arranged at intervals from left to right, or the feeding station may be located between the measuring station and the material cleaning station, or the material cleaning station may be located between the feeding station and the measuring station.
