Description

Technical Field

[0001] The utility model relates to the technical field of determination of tobacco filling value, and specifically, to a multi-station rotary device for determining the tobacco filling value of cigarettes. Background Art

[0002] The quality of tobacco has a great influence on the sensory quality of cigarettes and also has a greater impact on the effective operation rate of cigarette making and tipping equipment; the filling ability of tobacco 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 (including cut tobacco, expanded cut tobacco, reconstituted tobacco shreds, etc.) and expanded stem tobacco. 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 Tobacco, JJG (Tobacco) 25-2010 Verification Regulation for Tobacco Filling Value Measuring Instrument, and JJG (Tobacco) 26-2010 Verification Regulation for Expanded Stem Tobacco Filling Value Measuring Instrument.

[0004] At present, there is only one measuring barrel in the tobacco filling value measuring instruments on the market. When conducting detection, it is necessary to manually feed materials into the measuring barrel, then place the measuring barrel at the detection position for waiting for detection. After the detection is completed, the measuring barrel is manually cleaned. Then, materials are manually fed again for the next filling value detection. Such repeated operations result in high labor intensity, high labor cost, and low detection efficiency.

[0005] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the Invention

[0042] The technical solutions of the present utility model will be further described in detail below through specific embodiments.

[0043] Embodiment 1

[0044] As Figures 1-6 shown, this embodiment provides a multi-station rotary cigarette tobacco filling value measuring device, including a moving frame 1, a top plate 2, a reference plate 3, at least three cup barrel assemblies that are open at both the top and bottom, a rotating assembly, a feed hopper 4, a measuring assembly, a cleaning assembly, and a recycling bin 5;

[0045] The top plate 2 is installed on the top of the moving frame 1. The reference plate 3 is fixedly arranged on the upper surface of the top plate 2. Each cup and barrel assembly is arranged in a circumferential array on the reference plate 3. The rotating assembly is installed on the top plate 2 and fixedly connected to each cup and barrel assembly. The rotating assembly drives each cup and barrel assembly to intermittently rotate on the reference plate 3 at an angle between adjacent two cup and barrel assemblies. The lower end of the cup and barrel assembly is in sealed sliding contact with the upper surface of the reference plate 3.

[0046] There are three workstations on the reference plate 3 along the movement track of the cup and barrel assembly: the feeding workstation, the measuring workstation, and the cleaning workstation. The feeding workstation, the measuring workstation, and the cleaning workstation are arranged in sequence according to the rotating direction of the cup and barrel assembly. The reference plate 3 is provided with a first blanking hole 6 at the cleaning workstation. The top plate 2 is provided with a second blanking hole 7 at the cleaning workstation. The inner diameter of the second blanking hole 7 ≥ the inner diameter of the first blanking hole 6 ≥ the inner diameter of the cup and barrel assembly. The outer diameter of the cup and barrel assembly > the inner diameter of the first blanking hole 6.

[0047] The feeding hopper 4 is arranged above the feeding workstation for filling a fixed amount of cut tobacco into the cup and barrel assembly located at the feeding workstation.

[0048] The measuring assembly is arranged above the measuring workstation for measuring the filling value of the cut tobacco in the cup and barrel assembly located at the measuring workstation.

[0049] The cleaning assembly is arranged above the cleaning workstation for pushing out the cut tobacco in the cup and barrel assembly located at the cleaning workstation and enabling the cut tobacco to fall through the first blanking hole 6 and the second blanking hole 7.

[0050] The recovery bin 5 is fixedly installed at the inner bottom of the moving frame 1 and is located directly below the second blanking hole 7 for receiving the cut tobacco pushed out from the cup and barrel assembly by the cleaning assembly.

[0051] The cup and barrel assembly includes a cup body 8. The cup body 8 is open at both the upper and lower ends. A circular ring flange 9 is integrally formed on the outer circumference of the lower end of the cup body 8. A bottom support 10 sleeved on the lower end of the cup body 8 is fixedly connected to the lower end of the circular ring flange 9. A circular ring step in contact with the lower end of the cup body 8 is integrally formed on the inner circle of the lower end of the bottom support 10. The inner diameter of the circular ring step is the same as the inner diameter of the cup body 8. The outer diameter of the bottom support 10 > the inner diameter of the first blanking hole 6 ≥ the inner diameter of the cup body 8. The lower end surface of the bottom support 10 presses on the upper surface of the reference plate 3 and is in sealed sliding contact with the upper surface of the reference plate 3. The contact between the bottom support 10 and the reference plate 3 is smooth. After the fixed amount of cut tobacco is filled into the cup body 8, it rotates with the cup body 8 on the reference plate 3, and the bottom support 10 ensures that as little cut tobacco as possible leaks out.

[0052] The rotating assembly includes a rotating support plate 11 and a hollow rotating platform 12. The rotating support plate 11 is arranged directly above the reference plate 3. The hollow rotating platform 12 is fixedly installed in the middle of the top plate 2. The reference plate 3 is an annular plate. The hollow rotating platform 12 is located in the inner hole of the reference plate 3. The rotating support plate 11 is fixedly installed at the upper end of the hollow turntable of the hollow rotating platform 12. A number of card slots arranged in a circumferential array are provided on the outer circumference of the rotating support plate 11. Each cup body 8 is respectively and correspondingly clamped in each card slot. Rotary plungers 14 are installed on both sides of each card slot on the rotating support plate 11. Positioning holes are provided on the annular flange 9 of the corresponding cup body 8 at the positions corresponding to the rotary plungers 14. The lower end of the rotary plunger 14 is correspondingly inserted into the corresponding positioning hole. During operation, the hollow turntable of the hollow rotating platform 12 drives the rotating support plate 11 to rotate intermittently. The angle of each rotation is the angle between adjacent two cup bodies 8. Furthermore, the rotating support plate 11 drives each cup body 8 to rotate a certain angle together, ensuring that each rotation of the cup body 8 is exactly at the position where the previous cup body 8 was located. The rotary plunger 14 is used for positioning and restricting the cup body 8.

[0053] The measuring assembly includes a horizontal support plate 15, a pressing bottom plate 16, a vertical plate 17, a ball screw type linear module 18, a pressing head 19, a guiding optical axis 20, a positioning pin 21, a counterweight 22 and a magnetic scale reading head 23. The horizontal support plate 15 is fixedly arranged above each cup body 8. Three notches 24 corresponding to the feeding station, the measuring station and the material cleaning station up and down are circumferentially formed in the horizontal support plate 15. The pressing bottom plate 16 is fixedly installed in the middle of the upper surface of the horizontal support plate 15. The vertical plate 17 is fixedly installed on the upper surface of the pressing bottom plate 16 and is located on one side close to the center of the horizontal support plate 15 above the measuring station. The ball screw type linear module 18 is vertically and fixedly installed on one side surface of the vertical plate 17 facing away from the measuring station. The pressing head 19 is arranged directly above the cup body 8 at the measuring station. The outer diameter of the pressing head 19 is less than or equal to the inner diameter of the cup body 8. A guiding seat 25 located directly above the pressing head 19 is fixedly installed at the lower side of the side surface of the vertical plate 17 facing the measuring station. An installation hole is vertically formed in the guiding seat 25, and a linear bearing 26 is fixedly installed in the installation hole. The guiding optical axis 20 is slidably installed through the linear bearing 26. The pressing head 19 is fixedly installed at the lower end of the guiding optical axis 20. A supporting block 27 and an upper end plate 28 are arranged on the upper end of the guiding optical axis 20 from bottom to top. The rod portion of the positioning pin 21 passes through the supporting block 27 and the upper end plate 28 from top to bottom and is fixedly connected to the upper end of the guiding optical axis 20. The head of the positioning pin 21 presses against the upper surface of the upper end plate 28, thereby fixing the supporting block 27 and the upper end plate 28 at the upper end of the guiding optical axis 20. A positioning groove adapted to the head of the positioning pin 21 is formed in the center of the bottom of the counterweight 22. The counterweight 22 is placed on the upper surface of the upper end plate 28, and the positioning groove is fitted over the head of the positioning pin 21. A guiding long hole 29 is vertically formed in the vertical plate 17 on one side of the ball screw type linear module 18 and above the linear bearing 26. A supporting arm 30 is integrally formed on one side of the supporting block 27. A lifting bracket 31 is fixedly installed on the slider of the ball screw type linear module 18. The lifting bracket 31 passes through the guiding long hole 29 and moves up and down in the guiding long hole 29. The supporting arm 30 supports on the lifting bracket 31. The length of the guiding optical axis 20 > the length of the guiding long hole 29 > the distance from the upper end of the guiding seat 25 to the lower end of the cup body 8. The magnetic scale reading head 23 is fixedly installed on the side surface of the vertical plate 17 facing the measuring station. A magnetic strip block 32 arranged vertically and adapted to slidably contact the magnetic scale reading head 23 is fixedly installed on the supporting arm 30. The magnetic scale reading head 23 and the magnetic strip block 32 form a magnetic scale. In other embodiments, the ball screw type linear module 18 can also be replaced by a synchronous belt type linear module or a linear motor type linear module, or other linear reciprocating motion mechanisms. The horizontal support plate 15 and the feeding hopper 4 are fixed on the top plate 2 through an outer frame, and the outer frame is not shown in the figure.

[0054] The working principle of the measuring component in this embodiment is as follows. Before the cup body 8 filled with a fixed amount of tobacco shreds rotates to the measuring station, the lifting bracket 31 lifts the supporting arm 30 to the higher side of the guiding long hole 29, and the pressing head 19 is higher than the cup body 8 and maintains a certain distance. When the cup body 8 filled with a fixed amount of tobacco shreds rotates to the measuring station, the slider of the ball screw type linear module 18 drives the lifting bracket 31 to move downward to the lower side of the guiding long hole 29. Then, the pressing head 19 falls downward into the cup body 8 under its own weight and presses on the tobacco shreds. The lifting bracket 31 is separated from the supporting arm 30, and the guiding optical axis 20 can slide downward along the linear bearing 26. The weights of the counterweight 22 and the pressing head 19 are completely pressed on the tobacco shreds in the cup body 8. The magnetic strip block 32 moves downward together with the supporting arm 30 and the downward displacement distance of the pressing head 19 after the pressing head 19 presses on the tobacco shreds for a certain time is detected by the magnetic grating head 23, and thus the filling value of the tobacco shreds can be measured. After that, the slider of the ball screw type linear module 18 drives the lifting bracket 31 to move upward to the upper end of the guiding long hole 29. The lifting bracket 31 lifts the supporting arm 30 to move upward, so that the guiding optical axis 20 drives the pressing head 19 to be lifted upward, and the pressing head 19 is lifted out of the cup body 8 and away from the cup body 8, waiting to measure the filling value of the tobacco shreds in the next cup body 8.

[0055] The material cleaning component includes an electric push rod 33. The electric push rod 33 is vertically arranged directly above the cup body 8 at the material cleaning station. The piston rod of the electric push rod 33 extends from the lower end of the cylinder block. A brush wheel 34 is fixedly installed at the lower end of the piston rod of the electric push rod 33. The outer diameter of the brush wheel 34 is the same as the inner diameter of the cup body 8. The upper end of the cylinder block of the electric push rod 33 is fixedly installed on one side of the vertical plate 17 through a cantilever block. When the tobacco shreds in the cup body 8 rotate to the material cleaning station after the filling value measurement, the piston rod of the electric push rod 33 extends downward, so that the brush wheel 34 extends into the lower cup body 8, directly pushes the tobacco shreds in the cup body 8 downward, and the tobacco shreds fall into the lower recovery bin 5 through the first blanking hole 6 and the second blanking hole 7. At the same time, the brush wheel 34 cleans the inner wall of the cup body 8. Then, the piston rod of the electric push rod 33 contracts upward to reset, and the brush wheel 34 is lifted out of the cup body 8 to reset. The brush wheel 34 here can be a wool wheel. The empty cup barrel assembly after cleaning will rotate in a cycle to the feeding station to refill a fixed amount of tobacco shreds again.

[0056] This embodiment further includes a cleaning assembly, which includes at least two scraping plates 35. Each scraping plate 35 is arranged in a circumferential array and is vertically disposed along the radial direction of the rotating support plate 11 between the reference plate 3 and the rotating support plate 11.
