Technical Field

[0001] The utility model relates to the technical field of calibration of standard parts of cigarette detection instruments, in particular to a period checking device for a constant current hole. Background Art

[0002] The tobacco-specific standard constant flow orifice is a standard measuring instrument used on a variety of tobacco-specific testing instruments such as draw resistance testing equipment and ventilation rate testing equipment. Its main function is to keep the gas flow rate constant at a flow rate that meets the measurement requirements.

[0003] In the actual production process of tobacco, it is necessary to often use equipment such as absorption resistance measuring instruments and ventilation rate measuring instruments. Constant flow holes, as devices for generating stable airflow, are prone to tobacco pollution and blockage, and cannot ensure that the airflow in the air path is stable within the measurement requirements. In order to ensure the flow stability of the constant flow holes, it is necessary to conduct periodic inspections of the constant flow holes. The tobacco industry calibrates the tobacco-specific standard constant flow holes in accordance with JJG (Tobacco) 16-2002 "Tobacco-specific Standard Constant Flow Hole Calibration Procedure". Compressed air, flow meters, differential pressure gauges, etc. are required during the calibration process, and the calibration cycle is one year.

[0004] In the existing constant current hole period inspection device, after testing a constant current hole, it is necessary to manually remove the tested constant current hole and replace it with the next constant current hole to be tested. The labor cost is high and the efficiency is low, especially when batch inspection is performed. Utility Model Content

DETAILED DESCRIPTION

[0031] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0032] Embodiment 1

[0033] like Figure 1-8 As shown, this embodiment provides a period checking device for a constant flow orifice, including a control component 4 and an automatic feeding component 2, one end of the automatic feeding component 2 is connected to a flow generating component 3, and the other end is connected to a flow meter 1. The automatic feeding component 2, the flow generating component 3 and the flow meter 1 are all electrically connected to the control component 4.

[0034] The automatic feeding assembly 2 includes a feed roller 2-10, on which a station for placing a constant flow hole 2-11 is provided, and the stations for placing the constant flow hole 2-11 include a feeding station 6, a code scanning station 7, a detection station 8, and a blanking station 9. A code scanning unit is provided above the feed roller 2-10, and a verification and fixing unit is provided on one side of the feed roller 2-10, and a silo 2-2 is provided on the other side. The feed roller 2-10 is connected to the output end of the motor 2-9. The motor 2-9 is used to drive the feed roller 2-10 to rotate, and then the constant flow hole 2-11 on it rotates, so that the constant flow hole 2-11 passes through the code scanning unit and the verification and fixing unit in sequence. The automatic feeding assembly 2 can realize the automatic feeding function of the constant flow hole 2-11 during the verification, and the recording function of the unique barcode 2-11-1 can prevent the confusion and misdetection of information, saving human resources while improving the efficiency of the period verification.

[0035] The checking and fixing unit includes a constant flow hole pressure strip 2-12 and a clamping cylinder 2-15, the clamping cylinder 2-15 is mounted on the clamping cylinder fixing plate 2-14, and a clamping claw 2-16 is mounted on the clamping cylinder 2-15. The constant flow hole pressure strip 2-12 can press and fix the constant flow hole 2-11 located at the detection station 8 to prevent the constant flow hole 2-11 from falling off the material distribution roller 2-10.

[0036] The clip that passes through the clamping jaw 2-16 is provided with a constant flow hole sealing seat 2-17, one end of the constant flow hole sealing seat 2-17 is connected to the constant flow hole 2-11, and the other end thereof is connected to the spring air pipe 2-19 through the air pipe joint 2-18. Because the clamping jaw 2-16 has two clips, there are two groups of spring air pipes 2-19, which are respectively located at the two ends of the verification fixed unit, and the ends of the two groups of spring air pipes 2-19 that are away from each other are respectively connected to the flow generating component 3 and the flow meter 1. The two groups of spring air pipes 2-19 can make the constant flow hole 2-11 communicate with the flow generating component 3 and the flow meter 1 through the constant flow hole sealing seat 2-17, forming a period verification device, and performing period verification on the constant flow hole 2-11 to be verified.

[0037] The code scanning unit includes a code scanning module 2-7 and an electric clamp 2-5. The electric clamp 2-5 can move up and down under the action of the lifting cylinder 2-4, and the electric clamp 2-5 can rotate. A barcode 2-11-1 is provided on the constant flow hole 2-11. The lifting cylinder 2-4 drives the electric clamp 2-5 to move up and down so that the constant flow hole 2-11 clamped by the electric clamp 2-5 can be close to the code scanning module 2-7. At the same time, the electric clamp 2-5 rotates to align the barcode 2-11-1 on the constant flow hole 2-11 with the code scanning module 2-7, and then the barcode 2-11-1 is scanned by the code scanning module 2-7 to record the information of the constant flow hole 2-11 to be checked. The barcode 2-11-1 on each constant flow hole 2-11 corresponds to the constant flow hole 2-11 one by one to prevent information confusion during batch verification.

[0038] The flow generating assembly 3 includes an air source 3-1 and a vacuum generator 3-4, a control valve 3-2 is provided between the air source 3-1 and the vacuum generator 3-4, and a high-precision pressure gauge 3-3 is provided between the air source 3-1 and the control valve 3-2. The air source 3-1 can filter oil mist from the air.

[0039] The device of the utility model further comprises a base 5 , on which the control component 4 , the automatic feeding component 2 , the flow generating component 3 and the flow meter 1 are all arranged.

[0040] The working principle of the utility model is as follows: a batch of constant flow holes 2-11 with barcodes 2-11-1 are placed in a material bin 2-2, and then the constant flow holes 2-11 are placed in turn on the feeding station 6 of the material distribution roller 2-10 by using the material bin 2-2, and the material distribution roller 2-10 is driven to rotate by the motor 2-9, so that the material distribution roller 2-10 can drive the constant flow holes 2-11 on it to rotate, and when the constant flow holes 2-11 rotate to the barcode detection station (scanning station 7), the electric clamp is used to The claw 2-5 clamps the constant flow hole 2-11, and the lifting cylinder 2-4 drives the electric clamp 2-5 to rise close to the code scanning module 2-7. At the same time, the electric clamp 2-5 rotates to align the barcode 2-11-1 with the code scanning module 2-7. The code scanning module 2-7 scans the barcode 2-11-1 to record the information of the constant flow hole 2-11 to be checked, and then the lifting cylinder 2-4 descends, and the electric clamp 2-5 is released to return the constant flow hole 2-11 to the barcode detection station (code scanning station 7). The material distribution roller 2-10 continues to rotate, and when it reaches the detection station 8, the constant flow hole 2-11 is clamped by the clamp 2-16 on the clamping cylinder 2-15, so that the constant flow hole 2-11 is connected to the flow generating component 3 and the flow meter 1 through the constant flow hole sealing seat 2-17, and the constant flow hole 2-11 begins to be detected. After the detection is completed, the clamping cylinder 2-15 is released, the material distribution roller 2-10 continues to rotate, and finally the constant flow hole 2-11 falls into the receiving hopper 2-20 below the material distribution roller 2-10. The automatic feeding function of the constant flow hole 2-11 during the inspection is realized, which saves human resources and improves the efficiency of the inspection during the inspection.
