[0001] The utility model relates to the technical field of calibration of standard parts of cigarette detection instruments, and particularly relates to a device for interim verification of a tobacco draw resistance standard rod. Background Art

[0002] Draw resistance is the direct experience of the comfort of consumers when smoking cigarettes, and it is also an important physical property index in cigarette quality inspection. Therefore, it is necessary to use special tobacco draw resistance detection equipment to detect the draw resistance of tobacco.

[0003] As a standard measuring instrument for draw resistance detection equipment, the draw resistance standard rod is easily contaminated by tobacco shreds and blocked during the draw resistance detection process, resulting in inaccurate assignment. To ensure the accurate assignment of the draw resistance standard rod, it is necessary to conduct interim verification on the draw resistance standard rod.

[0004] In the existing interim verification device for draw resistance standard rods, during verification, after testing one draw resistance standard rod, it is necessary to manually remove the tested draw resistance standard rod and replace it with the next draw resistance standard rod to be tested. The labor cost is relatively high and the efficiency is low, especially obvious when conducting batch verification. Content of the Utility Model

[0005] To overcome the deficiencies of the above-mentioned prior art, the utility model provides a device for interim verification of a tobacco draw resistance standard rod, which can automatically replace the draw resistance standard rod to be verified, is suitable for batch verification of draw resistance standard rods, improves the verification efficiency, and saves labor costs.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A device for interim verification of a tobacco draw resistance standard rod includes an electric control box and a draw resistance detection unit. One end of the draw resistance detection unit is provided with a bin unit and an auxiliary feeding unit;

[0008] The bin unit includes a bin. The inside of the bin is provided with a first inclined plane. The low end of the first inclined plane is slidably connected to a standard rod lifting block.

[0011] As a further implementation method, an arc-shaped positioning plate is provided at the top of one side of the silo close to the lower end of the first inclined plane.

[0012] As a further implementation method, after the top of the standard rod lifting block slides upward in place, it is adapted to the arc-shaped positioning plate, and after sliding downward in place, it is adapted to the lower end of the first inclined plane.

[0013] As a further implementation method, the silo unit further includes an inspected silo, the inspected silo is adjacent to the silo, a second inclined plane is provided inside the inspected silo, and the inclination direction of the second inclined plane is opposite to that of the first inclined plane.

[0014] As a further implementation method, the three-axis moving platform includes a linear module, a first slider is slidably installed on the linear module, a transverse electric slide is fixedly installed on the first slider, and a second slider is slidably installed on the transverse electric slide.

[0020] The beneficial effects of the above-mentioned utility model are as follows:

[0021] The utility model provides an in - period verification device for a tobacco draw resistance standard rod. Through the settings of the first pneumatic slide, the first inclined plane, the standard rod lifting block and the arc - shaped positioning plate of the bin unit, the picking up of a single draw resistance standard rod in the bin is realized. By means of the settings of the second pneumatic slide and the push plate, one end of the single draw resistance standard rod can be exposed, which is convenient for the pneumatic gripper to grab. The three - axis moving platform of the auxiliary feeding unit is used to move the grabbed draw resistance standard rod to the barcode scanner for barcode registration, preventing the confusion of verification information of multiple draw resistance standard rods during batch verification. The registered draw resistance standard rod is moved to the draw resistance detection unit for in - period verification.

[0032] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present utility model. Unless otherwise specified, all technical and scientific terms used in the present utility model have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs.

[0033] Embodiment 1

[0034] As Figures 1-8 shown, this embodiment provides a device for periodic verification of a tobacco suction resistance standard rod, including an electric control box 1 and a suction resistance detection unit 5. One end of the suction resistance detection unit 5 is provided with a bin unit 3 and an auxiliary feeding unit 4. The suction resistance detection unit 5, the bin unit 3, and the auxiliary feeding unit 4 are all electrically connected to the electric control box 1. And a control panel 2 is provided on the electric control box 1. The operation of the control panel 2 is used to realize the automatic feeding function for the periodic verification of the suction resistance standard rod 5-9. While saving manpower, the efficiency of the periodic verification is improved.

[0035] Among them, the bin unit 3 includes a bin 3-1. A first inclined surface is provided inside the bin 3-1. The low end of the first inclined surface is slidably connected to the standard rod lifting block 3-4. The standard rod lifting block 3-4 is connected to the first pneumatic slide 3-3-1. One side of the bin 3-1 close to the low end of the first inclined surface is provided with an arc-shaped positioning plate 3-5. A sliding push plate mechanism is provided on the arc-shaped positioning plate 3-5. Under the action of the first pneumatic slide 3-3-1, after the top of the standard rod lifting block 3-4 slides upward in place, it fits with the arc-shaped positioning plate 3-5, so that the suction resistance standard rod 5-9 can roll into the arc inside the arc-shaped positioning plate 3-5. After sliding downward in place, it fits with the low end of the first inclined surface and can be slightly lower than the low end of the first inclined surface, so that the first suction resistance standard rod 5-9 located at the low end on the first inclined surface can slide onto the standard rod lifting block 3-4.

[0036] The first inclined plane can preliminarily arrange the draw resistance standard rods 5-9 placed inside the bin 3-1. The inclination angle of the first inclined plane is determined through experiments. The standard rod lifting block 3-4 located at the lower end of the first inclined plane can lift the first draw resistance standard rod 5-9 at the lower end of the first inclined plane to the arc positioning plate 3-5 under the action of the first pneumatic slide 3-3-1, so that the draw resistance standard rod 5-9 can roll into the arc inside the arc positioning plate 3-5.

[0037] The sliding push plate mechanism includes a chute on the arc positioning plate 3-5. A push plate is slidably connected inside the chute, and the push plate is connected to the second pneumatic slide 3-3-2. The second pneumatic slide 3-3-2 drives the push plate to move, thereby pushing the draw resistance standard rod 5-9 on the arc positioning plate 3-5 to move, exposing one end for the pneumatic gripper 4-6 to grab.

[0038] The auxiliary feeding unit 4 includes a three-axis moving platform. A barcode scanner 4-7 and a pneumatic gripper 4-6 are installed on the three-axis moving platform. The pneumatic gripper 4-6 is connected to the output end of the rotary motor 4-5. The rotary motor 4-5 can drive the pneumatic gripper 4-6 to rotate 360 degrees, so that the barcode scanner 4-7 can scan the barcode on the draw resistance standard rod 5-9.

[0039] The three-axis moving platform includes a linear module 4-1. A first slider 4-2 is slidably installed on the linear module 4-1. A transverse electric slide 4-3 is fixedly installed on the first slider 4-2. A second slider is slidably installed on the transverse electric slide 4-3. A barcode scanner 4-7 and a vertical electric slide 4-4 are fixedly installed on the second slider. The pneumatic gripper 4-6 is slidably installed on the vertical electric slide 4-4. This design enables the pneumatic gripper 4-6 on the three-axis moving platform to move three-dimensionally, facilitating operation.

[0040] The draw resistance detection unit 5 includes a standard rod fixture 5-8, and the standard rod fixture 5-8 is a pneumatic coating film. The standard rod fixture 5-8 is located at one end of the draw resistance detection unit 5 close to the bin unit 3 and the auxiliary feeding unit 4.

[0041] The bin unit 3 further includes an inspected bin 3-6. The inspected bin 3-6 is adjacent to the bin 3-1. A second inclined plane is provided inside the inspected bin 3-6, and the inclination direction of the second inclined plane is opposite to that of the first inclined plane. After the draw resistance standard rod 5-9 is detected, the auxiliary feeding unit 4 takes out the draw resistance standard rod 5-9 and puts it into the inspected bin 3-6.

[0042] The working principle of the present utility model:

[0043] Place a batch of resistance standard rods 5-9 with barcodes in the bin 3-1. During startup, check the instrument. The first pneumatic slide 3-3-1 drives the standard rod lifting block 3-4 at the innermost side in the bin 3-1 to lift a single resistance standard rod 5-9 upward. After moving into place, the resistance standard rod 5-9 will roll into the circular arc groove of the arc-shaped positioning plate 3-5. Then, the second pneumatic slide 3-3-2 drives the push plate inside the arc-shaped positioning plate 3-5 to move outward, thereby pushing the resistance standard rod 5-9 to move outward and exposing one end of the resistance standard rod 5-9. Subsequently, the three-axis moving platform of the auxiliary feeding unit 4 moves the rotatable pneumatic gripper 4-6 into place, grabs the resistance standard rod 5-9 and then displaces it. It moves to the barcode scanner 4-7. The rotation motor 4-5 drives the pneumatic gripper 4-6 to rotate, thereby driving the resistance standard rod 5-9 to rotate. The barcode scanner 4-7 scans the barcode on the resistance standard rod 5-9 and enters the information of the resistance standard rod 5-9 into the control panel 2. Then, the resistance standard rod 5-9 is moved in front of the standard rod fixture 5-8 and waits to be inserted after the standard rod fixture 5-8 expands (the standard rod fixture 5-8 is a pneumatic coating film). After insertion, the coating film shrinks and clamps the resistance standard rod 5-9. According to the verification regulation, start the resistance detection unit 5 to conduct an interim verification on the resistance standard rod 5-9. After the detection is completed, the auxiliary feeding unit 4 takes out the resistance standard rod 5-9 again and places it in the inspected bin 3-6. Repeat the operation according to the number of standard rods.

[0044] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
