Description

Technical Field

[0001] The utility model relates to the technical field of pipeline wind speed detection, in particular to a device for quickly detecting the wind speed of a cigarette wire feeding pipe. Background Art

[0002] With the diversification of cigarette varieties and the improvement of the refinement degree of cigarette production, new and higher requirements are put forward for the quality of cut tobacco, the breakage rate of cut tobacco, and the stable transportation and supply of cut tobacco in cigarette production. It is required that the cut tobacco and wind speed transported by the pneumatic wire feeding pipeline are stable without large fluctuations. Therefore, it is necessary to detect or regularly sample the pipeline wind speed in different pipeline sections during the installation and commissioning of the pneumatic wire feeding system and the production wire feeding process, so as to guide the adjustment of the pneumatic valve to achieve the purpose of stabilizing the pipeline wind speed.

[0003] At present, in the tobacco industry, the common method for detecting the wind speed of a cigarette wire feeding pipe is to directly drill a measurement hole in the pipeline and then insert the measuring rod of the anemometer into the measurement hole for measurement. Since the measuring rod itself has a long strip structure and lacks a guiding and positioning device, it is easy to have a large deflection after being inserted into the measurement hole, thus affecting the accuracy of wind speed measurement. In addition, the measurement hole after measuring the wind speed will remain on the pipeline, and there is a potential risk of air leakage if only sealed with adhesive tape. Content of the Utility Model

[0004] The purpose of the utility model is to provide a device for quickly detecting the wind speed of a cigarette wire feeding pipe, so as to avoid large deflection of the measuring rod during use, improve the measurement accuracy, and reduce the air leakage risk of the pipeline after the wind speed measurement is completed.

[0005] In order to solve the above technical problems, the utility model adopts the following technical scheme: A device for quickly detecting the wind speed of a cigarette wire feeding pipe, including an anemometer, and further including:

[0006] A measurement quick-connection mechanism for fixedly connecting the air duct. The measurement quick-connection mechanism is provided with a guiding cylinder for aligning the measurement hole on the air duct. The guiding cylinder is used for the measuring rod of the anemometer to pass through and limit the large deflection of the measuring rod;

[0007] A sealing member for being arranged on the upper end surface of the guiding cylinder;

[0008] A plugging member for connecting the guiding cylinder and plugging the measurement hole to prevent air leakage from the measurement hole after the measurement is completed.

[0009] Preferably, the measurement quick-connection mechanism includes a locking belt for wrapping the air duct, a sealing strip arranged on the inner side surface of the locking belt and used for fitting the outer wall of the air duct, and the two ends of the locking belt are buckled through a quick-connect buckle.

[0010] More preferably, the locking belt is a steel belt, the guiding cylinder is arranged on the steel belt, and the sealing strip is bonded to the inner side of the steel belt and is provided with a through hole at the position corresponding to the guiding cylinder.

[0011] More preferably, the sealing member includes a sealing ring fixedly bonded to the upper end face of the guiding cylinder.

[0012] More preferably, the plugging member includes a plug for threaded connection with the guiding cylinder, and the bottom of the plug is flush with the inner wall of the air duct.

[0013] Compared with the prior art, by aligning the guiding cylinder on the measurement quick-connect mechanism with the measurement hole of the air duct, the measuring rod of the anemometer can be restricted by the guiding cylinder during the process of passing through the guiding cylinder and the measurement hole and extending into the air duct for wind speed measurement, thus avoiding large swings and deflections of the rod body, and effectively improving the measurement accuracy. In addition, after the measurement is completed, the guiding hole is connected by the plugging member and the measurement hole is plugged, which can effectively prevent air leakage from the measurement hole after the measurement. Plugging and leveling after measurement will not have any impact on the material transportation, wind speed, and wind pressure of the pipeline. It is used for the wind speed detection of the cigarette pipeline, especially suitable for multi-point wind speed measurement during the installation and commissioning of the cigarette wire-feeding ventilation pipeline system to guide the adjustment of the opening degree of the ventilation valve.

[0022] For the convenience of understanding by those skilled in the art, the present invention will be further described below in conjunction with the embodiments and the drawings. The content mentioned in the embodiments does not limit the present invention.

[0023] It should be noted in advance that in the present utility model, unless otherwise clearly specified and defined, terms such as "installation", "connection", "attachment", "fixation" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, in the present utility model, unless otherwise clearly specified and defined, the first feature being "above" or "below" the second feature may include the first and second features being in direct contact, or may include the first and second features not being in direct contact but being in contact through additional features therebetween.

[0024] As Figure 1 and Figure 2 shown, the rapid wind speed detection device for cigarette wire feeding pipes includes an anemometer 1, and it further includes: a measurement quick-connection mechanism 3 for fixedly connecting an air duct 4. The measurement quick-connection mechanism 3 is provided with a guiding cylinder 33 for aligning the measurement holes on the air duct 4. The guiding cylinder 33 is used for the measuring rod of the anemometer 1 to penetrate and restrict the large deflection of the measuring rod; a sealing member 2 for being arranged on the upper end surface of the guiding cylinder 33; a plugging member 6 for connecting the guiding cylinder 33 and plugging the measurement holes to prevent air leakage from the measurement holes after the measurement is completed.

[0025] In the above structure, the measurement quick-connection mechanism 3 includes a locking band 32 for wrapping the air duct 4, and a sealing strip 31 arranged on the inner side surface of the locking band 32 and used for fitting the outer wall of the air duct 4. The two ends of the locking band 32 are buckled by a quick-connection buckle 5.

[0026] As Figure 3 and Figure 4 shown, the locking band 32 is a steel band, the guiding cylinder 33 is arranged on the steel band, the sealing strip 31 is bonded to the inner side surface of the steel band and a through hole is opened at the position corresponding to the guiding cylinder 33. The locking band 32 is made of steel band material, has high strength and good elasticity, can firmly wrap the air duct 4, and ensures the stability of the measurement quick-connection mechanism 3. The design of the quick-connection buckle 5 enables the measurement quick-connection mechanism 3 to be quickly and conveniently connected to and separated from the air duct 4, improving the convenience and efficiency of operation.

[0027] The sealing member 2 in this embodiment includes a sealing ring fixedly bonded to the upper end surface of the guiding cylinder 33. When the measuring rod of the anemometer 1 is inserted into the guiding cylinder 33, the sealing ring can provide a good sealing effect, prevent the wind speed leakage during the wind speed measurement of the anemometer 1, and ensure the accuracy of the measurement data. In addition, the inner wall of the guiding cylinder 33 is provided with internal threads, and the plugging member 6 includes a plug for threadedly connecting with the guiding cylinder 33. The bottom of the plug is flush with the inner wall of the air duct 4, which is convenient for quick installation and disassembly. After the wind speed measurement is completed, the plug can effectively plug the measurement holes, prevent the internal wind speed of the air duct from leaking, and ensure the airtightness of the air duct and the stability of the wind speed.

[0028] After making a measurement hole at the measurement point where the wind speed of the air duct 4 needs to be detected, the working process of testing the internal wind speed of the pipeline using the rapid wind speed detection device for cigarette wire feeding pipes provided by the above-mentioned embodiment is as follows:

[0029] a. First, wrap the locking belt 32 and the sealing strip 31 of the measurement quick-connect mechanism 3 around the air duct 4 to be measured, so that the screw hole of the guiding cylinder 33 on the measurement quick-connect mechanism 3 is aligned with the measurement hole of the air duct 4;

[0030] b. In order to improve the alignment accuracy between the guiding cylinder 33 and the measurement hole, a positioning round rod can be inserted into the guiding cylinder 33 and the measurement hole. Then, pass the locking belt 32 through the locking hole of the quick-connect buckle 5, and lock the two ends of the locking belt 32 through the quick-connect buckle 5, so that the measurement quick-connect mechanism 3 is tightened on the measurement air duct 4. After pulling out the positioning round rod, at this time, the measurement quick-connect mechanism 3 is firmly locked on the air duct 4 and the measurement hole of the air duct 4 is aligned and communicated with the guiding cylinder 33;

[0031] c. Install the seal 2 on the guiding cylinder 33, and then insert the measuring rod of the anemometer 1 into the air duct 4 through the seal 2, the guiding cylinder 33, and the measurement hole in sequence. The inserted depth is adjusted by the length of the measuring rod of the anemometer 1 inserted. Those skilled in the art should know that the measuring rod has a small bent end. Therefore, first insert the bent end, and then by flipping the anemometer 1, the main body of the rod of the measuring rod can be perpendicular to the air duct 4. Then continue to extend the measuring rod into the air duct 4. Since there are gaps between the guiding cylinder 33 and the measurement hole and the measuring rod, the measuring rod has a movable space for flipping. And the seal 2 is an elastic deformation-capable sealing ring. Therefore, the sealing ring will not cause obstruction when the measuring rod is flipped. After flipping, the sealing ring can still keep close to the outer peripheral surface of the measuring rod to ensure sealing (in the drawings, in order to clearly show each structure, the gap between the seal and the measuring rod has been depicted larger, but actually it is in contact and can achieve sealing).

[0032] d. After the measurement is completed, pull out the measuring rod of the anemometer 1, and then screw on the plugging member 6, that is, the screw plug, on the guiding cylinder 33. The bottom of the screw plug is flush with the inner wall of the air duct 4 to avoid scratching and breaking the tobacco shreds conveyed in the air duct 4 by the measurement hole of the air duct 4 and the screw hole of the guiding cylinder 33. The seal between the screw plug and the guiding cylinder 33 is achieved through the seal 2 to prevent air leakage and pressure drop in the air duct 4.

[0033] The rapid wind speed detection device for cigarette wire feeding pipes of the present utility model adopts an innovative quick-connection mechanism for measurement. The air duct is locked by a steel strip and a sealing strip is used to ensure the sealing between the air duct and the measuring device. The guiding cylinder precisely guides the measuring rod of the anemometer, reduces the degree of deflection, improves the measurement accuracy, and realizes the rapid measurement of the wind speed at any point in the pipeline. After the measurement is completed, the measuring hole is quickly blocked by a plug connected by threads, effectively preventing air leakage, ensuring the stability of the wind speed, and the blocking and flattening will not have any impact on the material conveying, wind speed, and wind pressure in the pipeline. The overall design not only improves the detection efficiency and accuracy, but also reduces the maintenance cost and energy waste, while ensuring the continuity and stability of the production process. This device is used for the wind speed detection of cigarette pipelines, especially suitable for the multi-point wind speed measurement during the installation and commissioning of the cigarette wire feeding ventilation pipeline system to guide the adjustment of the opening of the ventilation valve, and has significant beneficial effects on improving the quality and efficiency of cigarette production.

[0034] In order to enable those of ordinary skill in the art to more conveniently understand the improvements of the present utility model over the prior art, some of the drawings and descriptions of the present utility model have been simplified, and the above embodiments are the preferred implementation schemes of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present utility model.
