Description

Detection probe sensitivity calibration fixture and gluing device Technical Field

[0001] This application relates to the technical field of cigarette processing, and in particular to a detection probe sensitivity calibration fixture and a gluing device. Background Technology

[0002] The cigarette making and filling unit is a core piece of equipment in cigarette production. It includes the cigarette rolling machine and the filling machine. The gluing device of the filling machine consists of a glue cylinder, a glue control roller, a glue application roller, a guide roller, and a lifting roller. This device applies glue to the filling paper sheets, which are then further processed to form a filling paper sheet of a certain length with latex adhesive. The glue cylinder of the gluing device is typically equipped with a detection probe to monitor the glue level. When the probe detects a glue level greater than or equal to a specified height, it indicates that the glue level in the cylinder is normal, and the gluing device operates normally. When the probe detects a glue level lower than the specified height, it indicates that the glue level in the cylinder is insufficient, and glue needs to be added.

[0003] After prolonged operation, the detection probe's sensitivity decreases, causing the gluing device to continue production even when the glue level in the glue cylinder is insufficient. This can lead to issues such as air leakage or cigarette tip breakage in the finished cigarettes. In traditional technology, to ensure the sensitivity calibration of the detection probe, the gluing device needs to adjust the probe's sensitivity in standby mode (i.e., when there is glue in the glue cylinder), which affects the production efficiency of the cigarette-making unit. Summary of the Invention

[0004] Therefore, it is necessary to provide a detection probe sensitivity calibration fixture and a gluing device to address the problem that traditional technologies require the gluing device to adjust the sensitivity of the detection probe in standby mode, which affects the production efficiency of the cigarette rolling unit.

[0005] The technical solution is as follows:

[0006] One embodiment provides a detection probe sensitivity calibration fixture, comprising:

[0007] Mounting base, the mounting base being used to be disposed inside the glue cylinder;

[0008] An adjustment mechanism having an adjustment section for facing the detection probe, the adjustment mechanism being movably disposed on the mounting base so that the adjustment section can move closer to or further away from the detection probe.

[0009] The aforementioned probe sensitivity calibration fixture, when in use, places the mounting base inside the glue cylinder. The adjustment mechanism can move on the mounting base to move the adjustment part closer to or away from the probe. The adjustment part of the adjustment mechanism can simulate the liquid level of the glue in the glue cylinder. Thus, even if there is no glue in the glue cylinder, the operator can treat the adjustment part as the liquid level and move the adjustment mechanism to simulate different liquid level heights to calibrate the sensitivity of the probe. Compared with traditional technology, the aforementioned probe sensitivity calibration fixture can calibrate the sensitivity of the probe even when there is no glue in the glue cylinder (e.g., during maintenance of the glue application device), without affecting the normal operation of the cigarette making unit, thereby improving the production efficiency of the cigarette making unit.

[0010] In one embodiment, the mounting base is provided with a guide portion, and the adjustment mechanism is guided and engaged with the guide portion so that the adjustment portion can move closer to or further away from the detection probe.

[0011] In one embodiment, the guide portion has a communicating guide cavity and a guide opening, the guide opening being disposed toward the detection probe, and the adjustment mechanism includes a slider disposed in the guide cavity and capable of reciprocating along the axial direction of the guide opening.

[0012] In one embodiment, the side wall of the mounting base is provided with an operation window, which communicates with the guide cavity, and the operation window extends radially along the axial direction of the guide opening.

[0013] In one embodiment, the side of the operation window facing the guide port is connected to the guide port.

[0014] In one embodiment, the slider has a strip-shaped hole, the radial direction of which extends along the axis of the guide opening. The adjustment mechanism also includes a positioning rod. A positioning part is provided on the side wall of the guide cavity opposite to the operation window. One end of the positioning rod passes through the operation window and the strip-shaped hole in sequence and is positioned and engaged with the positioning part. The other end of the positioning rod is provided with an abutment part, which abuts against the side of the slider facing the operation window.

[0015] In one embodiment, the positioning part is provided with a screw hole, the positioning rod is provided with an external thread, and the threaded part is screwed into the screw hole.

[0016] In one embodiment, the slider has a receiving groove on the side facing the operation window, the strip hole is provided on the bottom wall of the receiving groove, and the abutment is located in the receiving groove.

[0017] In one embodiment, the adjustment mechanism further includes a shim disposed between the side of the slider facing the operation window and the abutment portion.

[0018] Another embodiment of this application provides a gluing device, which includes a glue cylinder, a detection probe, and a detection probe sensitivity calibration fixture as described above. The detection probe is disposed in the glue cylinder and is positioned toward the adjustment unit.

[0019] In use, the aforementioned glue-applying device has its mounting base placed inside the glue cylinder. The adjusting mechanism can move on the mounting base to move the adjusting part closer to or further away from the detection probe. The adjusting part of the adjusting mechanism can simulate the liquid level of the glue in the glue cylinder. Thus, even if there is no glue in the glue cylinder, the operator can treat the adjusting part as the liquid level and move the adjusting mechanism to simulate different liquid level heights to calibrate the sensitivity of the detection probe. Compared with traditional technology, the aforementioned glue-applying device can calibrate the sensitivity of the detection probe even when there is no glue in the glue cylinder (e.g., when the glue-applying device is shut down for maintenance), without affecting the normal operation of the cigarette rolling machine, thereby improving the production efficiency of the cigarette rolling machine.

[0029] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0030] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, 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, and therefore should not be construed as a limitation of this application.

[0031] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., 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, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0034] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, 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 possible implementation.

[0035] Please refer to Figures 1 to 3. One embodiment of this application provides a detection probe sensitivity calibration fixture, including a mounting base 100 and an adjustment mechanism 200. The mounting base 100 is disposed inside a glue cylinder 10. The adjustment mechanism 200 has an adjustment part 210, which is disposed toward the detection probe 20. The adjustment mechanism 200 is movably disposed on the mounting base 100 so that the adjustment part 210 can be close to or away from the detection probe 20.

[0036] In use, the aforementioned probe sensitivity calibration fixture involves placing the mounting base 100 inside the glue cylinder 10. The adjusting mechanism 200 can move on the mounting base 100 to move the adjusting part 210 closer to or further away from the probe 20. The adjusting part 210 of the adjusting mechanism 200 can simulate the liquid level of the glue in the glue cylinder 10. Thus, even if there is no glue in the glue cylinder 10, the operator can use the adjusting part 210 as the liquid level and move the adjusting mechanism 200 to simulate different liquid level heights to calibrate the sensitivity of the probe 20. Compared with traditional technology, the aforementioned probe sensitivity calibration fixture can calibrate the sensitivity of the probe 20 even when there is no glue in the glue cylinder 10 (e.g., during maintenance of the glue application device), without affecting the normal operation of the cigarette making machine, thereby improving the production efficiency of the cigarette making machine.

[0037] As an explanation, in conventional technology, since there is no glue in the glue tank 10 during maintenance of the gluing device, the operator cannot calibrate the detection sensitivity of the detection probe 20 during maintenance. When the sensitivity of the detection probe 20 needs to be calibrated, the gluing device needs to be stopped during production. At this time, there is glue in the glue tank 10 so that the operator can calibrate the sensitivity of the detection probe 20. However, this method will delay the operating efficiency of the gluing device during production. In this embodiment, the adjustment part 210 of the adjustment mechanism 200 is used to simulate the liquid level of the glue, so that the operator can calibrate the sensitivity of the detection probe 20 when there is no glue in the glue tank 10, without affecting the operating efficiency of the gluing device during production, thereby improving the overall production efficiency of the cigarette making unit.

[0038] Furthermore, the mounting base 100 is used to be installed on the bottom wall of the glue tank 10; since the detection probe 20 is usually set facing the bottom surface of the glue tank 10 to detect the liquid level of the glue in the glue tank 10, based on this, setting the mounting base 100 at the bottom of the glue tank 10 can better simulate the glue.

[0039] Furthermore, the adjustment unit 210 is located on the side of the adjustment mechanism 200 away from the bottom of the glue cylinder 10. The adjustment mechanism 200 can be raised and lowered relative to the mounting base 100, thereby enabling the adjustment unit 210 to simulate different liquid level heights of the glue to perform multi-point calibration of the range coverage capability of the detection probe 20, thereby reducing the detection error of the detection probe 20.

[0040] In one embodiment, the plane containing the bottom wall of the glue cylinder 10 forms an angle with the ground, and the bottom of the mounting base 100 is inclined so that the bottom of the mounting base 100 matches the bottom wall of the glue cylinder 10.

[0041] As an explanation, the reason for setting the bottom wall of the glue cylinder 10 at an angle to the ground is to make room outside the glue cylinder 10 for installing other components. Therefore, in order to match the bottom wall of the glue cylinder 10, the bottom of the mounting base 100 is tilted so that the adjustment part 210 is parallel to the ground, thereby achieving a better simulation effect on the liquid surface of the glue.

[0042] Please refer to Figures 1 to 3. In one embodiment, the mounting base 100 is provided with a guide portion, and the adjustment mechanism 200 is guided and cooperated with the guide portion so that the adjustment portion 210 can move closer to or further away from the detection probe 20.

[0043] The adjustment mechanism 200 is guided and cooperated with the guide portion on the mounting base 100 so that the adjustment mechanism 200 can move on the mounting base 100, thereby driving the adjustment portion 210 to move closer to or further away from the detection probe 20; the setting of the guide portion can improve the movement stability of the adjustment mechanism 200 on the mounting base 100.

[0044] Optionally, the guide part can be a guide rail, guide groove, guide protrusion, or other structure that can cooperate with the adjustment mechanism 200 in a guiding manner; no specific limitation is made here.

[0045] Furthermore, the guide extends along the height direction so that the adjustment mechanism 200 can reciprocate relative to the mounting base 100 in the height direction, thereby allowing the adjustment part 210 to move closer to or further away from the detection probe 20.

[0046] Please refer to Figures 1 to 5. In one embodiment, the guide portion has a communicating guide cavity 110 and guide port 120. The guide port 120 is disposed toward the detection probe 20. The adjustment mechanism 200 includes a slider 220, which is disposed in the guide cavity 110 and can reciprocate along the axial direction of the guide port 120.

[0047] The slider 220 in the guide cavity 110 can reciprocate along the axis of the guide port 120, thereby driving the adjustment part 210 to move closer to or away from the detection probe 20. The arrangement of the guide cavity 110 and the guide port 120 can make the movement trajectory of the slider 220 more stable and improve the movement reliability of the slider 220.

[0048] Furthermore, the guide port 120 is located on the side of the guide cavity 110 away from the bottom wall of the glue cylinder 10, and at least a portion of the sliding member 220 is located in the guide cavity 110 and can reciprocate along the axial direction of the guide port 120, thereby driving the adjustment part 210 to move closer to or away from the detection probe 20.

[0049] Please refer to Figure 3. In one embodiment, the adjustment part 210 is provided with an adjustment surface, which is located on the side of the slider 220 away from the bottom wall of the guide cavity 110.

[0050] Please refer to Figure 5. In one embodiment, the side wall of the mounting base 100 is provided with an operation window 130. The operation window 130 communicates with the guide cavity 110, and the operation window 130 extends radially along the axial direction of the guide port 120.

[0051] The side wall of the guide cavity 110 is provided with an operation window 130 extending along the axis of the guide opening 120, so that the operator can adjust the position of the sliding member 220 through the operation window 130, thereby improving the ease of use of the calibration fixture.

[0052] As an explanation, in the above embodiment, the operation window 130 is open, and the radial direction of the operation window 130 refers to the direction perpendicular to the axial direction of the open operation window 130.

[0053] Please refer to Figure 5. In one embodiment, the side of the operation window 130 facing the guide port 120 is connected to the guide port 120.

[0054] This design can further improve the ease of operation for staff when adjusting the position of the sliding component 220 without affecting the guiding function of the guide cavity 110.

[0055] In addition, the operation window 130 and the guide port 120 are set to be in a connected state. When it is necessary to install the sliding block in the guide cavity 110, it can be installed through the guide port 120, the operation window 130, or the connection between the guide port 120 and the operation window 130, so as to simplify the installation process of the calibration fixture and improve the installation efficiency.

[0056] Furthermore, referring to Figure 5, the side of the operation window 130 facing the guide port 120 is connected to the guide port 120 so that the guide part forms a semi-open groove. This not only facilitates the installation of the sliding block, but also facilitates the reciprocating movement of the sliding block along the axis of the opening.

[0057] Please refer to Figures 2 to 6. In one embodiment, the slider 220 has a strip hole 221, which extends radially along the axis of the guide opening 120. The adjustment mechanism 200 also includes a positioning rod 230. A positioning part 111 is provided on the side wall of the guide cavity 110 opposite to the operation window 130. One end of the positioning rod 230 passes through the operation window 130 and the strip hole 221 in sequence and is positioned and engaged with the positioning part 111. The other end of the positioning rod 230 is provided with an abutment part 231, which abuts against the side of the slider 220 facing the operation window 130.

[0058] One end of the positioning rod 230 passes through the operating window 130 and through the strip hole 221, and is positioned and engaged with the positioning part 111 in the guide cavity 110. Since the radial direction of the strip hole 221 extends along the axis of the guide opening 120, after the positioning rod 230 passes through the strip hole 221, the sliding member 220 can still move back and forth along the axis of the guide opening 120, thereby driving the adjustment part 210 to move closer to or away from the detection probe 20. After adjusting the adjustment part 210 to the specified height, one end of the positioning rod 230 is positioned and engaged with the positioning part 111, so that the abutment part 231 of the other end of the positioning rod 230 abuts against the side of the sliding member 220 facing the operating window 130, thereby clamping the sliding member 220 between the abutment part 231 and the side wall of the guide cavity 110 opposite to the operating window 130, so as to achieve the positioning effect of the sliding member 220 and prevent the sliding member 220 from moving.

[0059] Furthermore, the setting of the operation window 130 also makes it easier for the staff to pass the positioning rod 230 through the strip hole 221 and position it in conjunction with the positioning part 111, which will not be elaborated here.

[0060] Optionally, the positioning method of the end of the positioning part 111 and the positioning rod 230 away from the abutment part 231 can be snap-fit, adhesive, screw-fit, etc., and no specific limitation is made here.

[0061] Please refer to Figures 4 and 6. In one embodiment, the positioning part 111 is provided with a screw hole 1111, and the positioning rod 230 is provided with an external thread, with the threaded part screwed into the screw hole 1111.

[0062] The threaded portion of the outer wall of the positioning rod 230 is screwed into the screw hole 1111, thereby achieving the positioning fit between the positioning rod 230 and the positioning part 111. This method has low implementation cost and reliable positioning effect.

[0063] Furthermore, the abutment part 231 is a bolt head located at one end of the positioning rod 230.

[0064] Please refer to Figures 2, 3, 5 and 6. In one embodiment, the slider 220 has a receiving groove 222 on the side facing the operation window 130, the strip hole 221 is provided on the bottom wall of the receiving groove 222, and the abutment part 231 is located in the receiving groove 222.

[0065] With this configuration, when the positioning rod 230 passes through the strip hole 221, the abutment part 231 at one end of the positioning rod 230 can be located in the receiving groove 222 to hide the abutment part 231, thereby reducing the space occupied by the calibration fixture in the glue cylinder 10. It can also prevent external parts from bumping the abutment part 231 and affecting the positioning effect of the positioning rod 230 and the positioning part 111.

[0066] Furthermore, to facilitate the processing of the receiving groove 222, the receiving groove 222 is an open groove.

[0067] Please refer to Figures 2, 3, 5 and 6. In one embodiment, the adjustment mechanism 200 further includes a shim 240, which is disposed between the side of the slider 220 facing the operation window 130 and the abutment portion 231.

[0068] The shim 240 prevents the abutment 231 from making hard contact with the outer wall of the slider 220, thus providing a certain degree of protection for the slider 220 and the abutment 231. In addition, the shim 240 also enables the abutment 231 and the slider 220 to maintain a tight state even under vibration, improving the reliability of the calibration fixture.

[0069] Optionally, the gasket 240 may be made of metal materials such as stainless steel and aluminum, or non-metal materials such as rubber and plastic; no specific limitation is made here.

[0070] Another embodiment of this application provides a gluing device, which includes a glue cylinder 10, a detection probe 20, and a detection probe sensitivity calibration fixture as described above. The detection probe 20 is disposed in the glue cylinder 10 and is positioned toward the adjustment section 210.

[0071] In use, the aforementioned gluing device has the mounting base 100 placed inside the glue cylinder 10. The adjusting mechanism 200 can move on the mounting base 100 to move the adjusting part 210 closer to or further away from the detection probe 20. The adjusting part 210 of the adjusting mechanism 200 can simulate the liquid level of the glue in the glue cylinder 10. Thus, even if there is no glue in the glue cylinder 10, the operator can use the adjusting part 210 as the liquid level of the glue and move the adjusting mechanism 200 to simulate different liquid level heights of the glue to calibrate the sensitivity of the detection probe 20. Compared with traditional technology, the aforementioned gluing device can calibrate the sensitivity of the detection probe 20 even when there is no glue in the glue cylinder 10 (e.g., when the gluing device is shut down for maintenance), without affecting the normal operation of the cigarette making unit, thereby improving the production efficiency of the cigarette making unit.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0073] The above embodiments merely illustrate several implementation methods of this application, and 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 those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
