Description

Technical Field

[0001] This utility model relates to the field of filter rod testing technology, and in particular to a pipeline-type pressure relief structure and an automatic sampling and testing device. Background Technology

[0002] In the cigarette production process, especially in the production of cigarette filter rods, it is necessary to test the filter rods. Automatic sampling and testing devices are widely used in this process. The automatic sampling module of an automatic sampling and testing device generally consists of three parts: a sampling section, a transmission section, and a receiving section. The automatic sampling process first requires using negative pressure to suck up the filter rod in the sampling section. Then, under negative pressure, the filter rod is transported through the transmission pipe in the transmission section to the receiving end of the integrated testing platform in the receiving section. Since the transmission pipe is generally installed above the integrated testing platform, the filter rod falls a relatively long distance vertically. Simultaneously, because a certain air pressure needs to be maintained during transmission, the transmission speed of the filter rod is relatively fast. Therefore, when the filter rod falls through the transmission pipe to the receiving end, a certain impact force is generated on the contact surface, causing some deformation of the filter rod end face, which affects the accuracy of subsequent physical property test results.

[0003] Therefore, there is an urgent need for a pipeline-type pressure relief structure that can be applied to an automatic sampling and testing device for tobacco tow filter rods to improve the above-mentioned problems. Utility Model Content

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0028] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0030] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0031] like Figures 1 to 4 As shown, this utility model discloses a pipeline-type pressure relief structure, including a pressure relief pipe body 1 and two connecting parts 3. The pressure relief pipe body 1 is configured as a hollow tube, with the two ends of the pressure relief pipe body 1 being an air inlet and an air outlet, respectively. The two connecting parts 3 are respectively connected to the air inlet and the air outlet for mounting the pressure relief pipe body 1 to form a connection with other structures. A pressure relief hole 2 is provided in the middle section of the pressure relief pipe body 1, which can be used to release the air source pressure inside the pressure relief pipe body 1.

[0032] In some embodiments, the pressure relief pipe body 1 is provided with a plurality of pressure relief holes 2 at intervals along its length direction, ensuring that the pressure relief holes 2 are evenly distributed along the length direction of the pressure relief pipe body 1, improving the pressure relief effect and avoiding insufficient pressure relief. In other embodiments, the pressure relief pipe body 1 is provided with a plurality of pressure relief holes 2 at intervals along its circumference, and the pressure relief holes 2 are evenly arranged around the perimeter of the pressure relief pipe body 1, further comprehensively improving the pressure relief uniformity of the pipeline pressure relief structure, and avoiding abnormal transmission processes caused by local areas not being radiated with the pressure relief effect during transmission operations of the pipeline pressure relief structure.

[0033] Furthermore, several pressure relief holes 2 are evenly distributed in multiple rows along the circumference of the pressure relief pipe body 1, and each row has multiple pressure relief holes 2 evenly distributed along the length of the pressure relief pipe body 1. The pressure relief holes 2 in two adjacent rows are staggered along the length of the pressure relief pipe body 1, so that the pressure relief holes 2 are evenly distributed on the pressure relief pipe body 1, making the pressure relief effect more uniform.

[0034] Specifically, in order to adapt to the structure of the pressure relief pipe body 1, the pressure relief hole 2 is set as an elongated hole, which extends along the length of the pressure relief pipe body 1, so as to release the gas source pressure better and more evenly.

[0035] For example, the length of a single elongated hole ranges from one-tenth to one-seventh of the length of the pressure relief pipe body 1, which can satisfy the pressure relief effect while also ensuring the structural strength of the pressure relief pipe body 1.

[0036] In this embodiment, the pressure relief pipe body 1 has rounded corners on the inner circumferential edge of the pressure relief hole 2 to prevent the material being transported in the pipeline pressure relief structure from sticking to the wall when passing through the pressure relief hole 2 due to the air source pressure, thus ensuring the working efficiency of the pipeline pressure relief structure.

[0037] This utility model also discloses an automatic sampling and testing device, including the above-mentioned pipeline pressure relief structure. The pipeline pressure relief structure is located in the transmission section of the automatic sampling and testing device, which can effectively solve the pressure relief problem in the transmission section, reduce the air source pressure during the transmission process, thereby reducing the transmission speed of the filter rod, reducing the impact force when the filter rod is transmitted to the receiving end, and effectively improving the problem of deformation of the rear end face of the filter rod when it is transmitted to the receiving end.

[0038] Optionally, connector 3 is configured as a connecting nut. The diameter of the connecting nut's bore is the same as the inner diameter of the pressure relief pipe body 1. Both ends of the connecting nut are provided with internal threads. One end of the connecting nut is threadedly connected to the pressure relief pipe body 1, and the other end of the connecting nut is threadedly connected to the transmission pipe of the transmission section. The connecting nuts at the inlet and outlet ends are sequentially connected to the transmission pipe of the transmission section along the transmission direction. The inner diameter of the pressure relief pipe body 1 is the same as the inner diameter of the transmission pipe, matching the diameter of the filter rod. The two ends of the pipe-type pressure relief structure are connected to the transmission pipe of the transmission section through connecting nuts, embedded in the middle of the transmission pipe. This allows for the replacement of a section of the transmission pipe at a suitable location without altering other structures of the automatic sampling and detection device. Through simple modification, a good pressure relief effect is achieved, effectively protecting the transmission safety of the filter rod.

[0039] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
