Description

Technical Field

[0001] The present application relates to the field of detection technology, and in particular to a suction ribbon detection device. Background Art

[0002] Suction ribbons are commonly used in the cigarette-making process to absorb shredded tobacco and transport it to the cigarette-rolling mechanism for rolling. The tension of the suction ribbon—the amount it stretches under a given tension—is a key indicator of its quality. If the tension is too low, the fixed length of the ribbon is too long, making it prone to slipping during use and causing serious problems with the quality of the cigarette rolls. If the tension is too high, the fixed length of the ribbon is too short, making it difficult to install and prone to wear.

[0003] To ensure safe cigarette production, tension testing of the suction ribbon is necessary. Conventional techniques typically involve manually adding a heavy object for tension testing, a cumbersome and potentially dangerous process. Furthermore, manual testing is inefficient and requires only a small sample size, posing a risk to the quality of the suction ribbon. Utility Model Content

[0030] In addition, if the term "and / or" appears, "and / or" is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent three situations: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the objects associated before and after are in an "or" relationship. If the terms "first" and "second" appear, these terms are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "multiple" appears, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0033] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only embodiment.

[0034] See Figure 1 As shown, the embodiment of the present application provides a suction ribbon detection device 100 that can be used to test the tension of a suction ribbon, thereby realizing automated testing of the suction ribbon and improving detection efficiency. It should be noted that for ease of understanding, the suction ribbon detection device 100 provided in this application is only illustrated using the tension test scenario of a suction ribbon as an example, but is not limited to tension testing of suction ribbons and can also be applied to tension testing of products such as tension belts, conveyor belts, ropes, and cables.

[0035] Specifically, the suction ribbon detection device 100 includes a bracket 110, a stretching component 120 and a detection component 130, wherein the bracket 110 can serve as an installation carrier for the stretching component 120 and the detection component 130, and the suction ribbon is stretched by the stretching component 120, and the stretched length of the suction ribbon is obtained by the detection component 130.

[0036] For example, the support 110 can be a metal welded workpiece or a wood spliced workpiece. The support 110 includes two vertical columns arranged opposite to each other along the direction of gravity and a horizontal beam arranged along the horizontal direction. The two opposite ends of the beam are respectively connected to the two columns to be fixed to the ground or work surface through the columns.

[0037] The stretching assembly 120 includes a driver 121 and two support ends 125. The driver 121 is mounted on one side of the beam. At least one of the two support ends 125 is retractable, 1251, which can be driven by the driver 121 to move telescopically along the beam's extension direction. During the suction ribbon inspection process, the spacing between the two support ends 125 is adjusted to ensure that the suction ribbon fits over the two support ends 125 without tension. The driver 121 then extends the retractable support end 1251, causing the suction ribbon to stretch.

[0038] The detection component 130 is installed on the retractable support end 1251. In an embodiment with two retractable support ends 1251, two detection components 130 can be provided and installed on different retractable support ends 1251 respectively to obtain the displacement of the retractable support end 1251, and then convert it into the stretching amount of the suction ribbon.

[0039] The working principle of this embodiment is as follows: the tension of the suction ribbon is preset to control the thrust of the driving member 121. When the thrust of the driving member 121 reaches the preset tension and remains stable, the suction ribbon is no longer stretched, thereby obtaining the stretching amount of the suction ribbon under the preset tension and judging the quality of the suction ribbon.

[0040] See Figure 2 and Figure 3 As shown, in some embodiments, the stretching assembly 120 further includes two semicircular blocks 124, mounted on two support ends 125. The suction ribbon is sequentially wound around the semicircular surfaces of the two semicircular blocks 124. This ensures that the ribbon conforms to the smooth curved surfaces during the stretching process, reducing wear on the ribbon. Furthermore, the radius of the semicircular blocks 124 can be set to match the radius of the pulleys of the cigarette production equipment to simulate the operating environment of the suction ribbon during the cigarette rolling process, thereby improving the accuracy of the suction ribbon detection.

[0041] Of course, in other embodiments, the semicircular block 124 may be replaced by a circular block, but the flat side of the semicircular block 124 is convenient for connection with the output end of the driving member 121 .

[0042] See again Figure 2 As shown, in some embodiments, one of the two support ends 125 is a retractable support end 1251, and the other is a fixed support end 1252. The semicircular block 124 provided at the fixed support end 1252 is fixed to the bracket 110, and the semicircular block 124 provided at the retractable support end 1251 is slidably connected to the bracket 110.

[0043] Specifically, the arcuate surfaces of the two semicircular blocks 124 face away from each other. The semicircular block 124 disposed at the fixed support end 1252 can be fixed to the side of the bracket 110 via a pin, bolt, or other workpiece. The semicircular block 124 disposed at the telescopic support end 1251 is connected to the output end of the driver 121 to move under the drive of the driver 121. At the same time, to maintain the smooth movement of the semicircular block 124, a slide groove can be provided on the side of the bracket 110 close to the driver 121. The semicircular block 124 disposed at the telescopic support end 1251 can be provided with a corresponding slider. The slider slides through the slide groove to achieve sliding guidance of the semicircular block 124 and maintain stable movement.

[0044] See again Figure 3 As shown, in some embodiments, both support ends 125 can be retractable support ends 1251, and the two semicircular blocks 124 are slidably connected to the bracket 110. Two drive members 121 are provided, and the output end of each drive member 121 is connected to a semicircular block 124, thereby synchronously driving the two semicircular blocks 124 to achieve the stretching of the suction ribbon. Similarly, a sliding structure similar to that in the above embodiment can be provided between the bracket 110 and the semicircular block 124 to ensure the stable movement of the semicircular block 124, which will not be repeated here.

[0045] In some embodiments, the driving member 121 may be a cylinder, and the stretching assembly 120 further includes an air source 123 connected to the cylinder via a pipeline. The air source 123 may be a compressed air system that delivers compressed air to the cylinder to control the telescopic movement of the cylinder output end.

[0046] In other embodiments, the driving member 121 may also be a hydraulic cylinder, and the air source 123 may be replaced by a hydraulic oil system, both of which can satisfy the telescopic driving function of the driving member 121.

[0047] In some embodiments, the stretching assembly 120 further includes an electrical proportional valve 122, which is disposed between the air source 123 and the cylinder and communicates with the air source 123 and the cylinder via pipelines. The electrical proportional valve 122 controls the open / closed state of the pipeline between the air source 123 and the cylinder. Thus, the electrical proportional valve 122 controls the air intake of the cylinder and limits the output thrust of the cylinder, thereby achieving a predetermined tension of the suction ribbon and maintaining stability.

[0048] See Figure 4 As shown, in some embodiments, the suction ribbon detection device 100 further includes a control component 140 , and the control component 140 includes a central processing unit 141 , and the central processing unit 141 is electrically connected to the stretching component 120 to limit the tension of the driving member 121 .

[0049] Specifically, a PLC (Programmable Logic Controller) control program is installed in the central processing unit 141 and is electrically connected to the electrical proportional valve 122 , thereby controlling the operating state of the electrical proportional valve 122 and limiting the output thrust of the driving member 121 .

[0050] In some embodiments, the control component 140 further includes a touch screen 142 , which is electrically connected to the central processing unit 141 and sends tension setting instructions to the central processing unit 141 .

[0051] Specifically, the touch screen 142 is located within the operator's field of view and, under the operator's control, can send corresponding instructions to the central processing unit 141. During the inspection process, the operator can set the corresponding preset tension for the inspection based on the different specifications of the suction ribbon. The preset tension signal is then sent to the central processing unit 141, which then controls the driver 121 to reach the preset tension value via the electrical proportional valve 122. Ultimately, the quality of the suction ribbon is determined based on the calculated relationship between the amount of stretch in the suction ribbon and the preset tension.

[0052] In some embodiments, the detection assembly 130 includes a displacement sensor electrically connected to the central processing unit 141. The displacement sensor is mounted on the retractable support end 1251 to detect the displacement of the retractable support end 1251 and convert the displacement into an electrical signal for transmission to the central processing unit 141. The central processing unit 141 converts the displacement of the retractable support end 1251 into the stretch of the suction ribbon using a calculation formula.

[0053] In some embodiments, the displacement sensor includes a pointer 131 fixed to the telescopic support end 1251 and a scale 132 mounted on the bracket 110, and the tip of the pointer 131 points to the scale line of the scale 132. Specifically, the pointer 131 can be mounted on the telescopic support end 1251 to follow the movement of the telescopic support end 1251 and read the scale line value of the scale 132. The displacement sensor can calculate the displacement of the telescopic support end 1251 based on the scale line value of the initial state of the pointer 131 and the scale line value after extension. At the same time, the design of the pointer 131 and the scale 132 facilitates direct observation by the operator, and when an electronic control failure occurs in the displacement sensor, the displacement data can still be read manually.

[0054] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
