Abstract
Description
Technical Field
[0001] This application relates to the field of cigarette production technology, and in particular to paper trays and tipping paper supply devices. Background Technology
[0002] Tipping paper is commonly used as a cigarette packaging material for the outer packaging of cigarette filter tips. To adapt to new production models, cigarette production now employs tipping paper supply devices to ensure uninterrupted supply of tipping paper. These devices use fully automated material addition and splicing, requiring no manual intervention. Therefore, equipment and product quality problems caused by material defects are not easily detected by operators at the source, leading to batch-wide product quality defects and significantly impacting equipment efficiency and product quality.
[0003] Specifically, the tipping paper is currently prone to shaking during the feeding process of the paper tray of the tipping paper supply device, resulting in defects such as inconsistent lengths of the tipping paper, which in turn affects the quality of the finished cigarette. Utility Model Content
[0004] Therefore, it is necessary to provide a paper tray and a paper feeding device to address the issue of improving the stability of tipping paper conveying.
[0005] In a first aspect, this application provides a paper tray holder, comprising:
[0006] A frame, on which a rotating shaft is provided for loading cork paper trays;
[0007] The paper guiding assembly includes multiple paper guiding rollers, which are spaced apart on the frame. The multiple paper guiding rollers work together to guide the tipped paper output from the tipped paper tray out of the paper tray frame. At least one of the paper guiding rollers is provided with two limiting rings, which are spaced apart along the axial direction of the paper guiding roller. A limiting groove for accommodating the tipped paper is formed between the two limiting rings.
[0008] The technical solution will be further explained below:
[0009] In one embodiment, the limiting ring is detachably connected to the paper guide roller, and the axial position of the limiting ring on the paper guide roller is adjustable.
[0010] In one embodiment, the outer peripheral surface of the limiting ring is provided with a threaded hole, and the paper tray holder also includes a threaded connector, which is threaded into the threaded hole and abuts against the paper guide roller to lock the limiting ring on the paper guide roller.
[0011] In one embodiment, chamfers are provided on the opposite sides of the two limiting rings.
[0012] In one embodiment, the frame includes a frame body and a tensioning arm, the tensioning arm being movably connected to the frame body, one of the paper guide rollers in the paper guide assembly being disposed on the tensioning arm, and the remaining paper guide rollers being disposed on the frame body, the paper guide rollers located on the tensioning arm being provided with the limiting ring, and the paper guide rollers on the tensioning arm being used to tension the cork paper.
[0013] In one embodiment, the number of the rotating shafts is two, namely a used rotating shaft and a spare rotating shaft, and the used rotating shaft and the spare rotating shaft are arranged alternately on the frame;
[0014] The number of paper guiding assemblies is two, namely a used paper guiding assembly and a spare paper guiding assembly. The used paper guiding assembly is used to export the tipped paper output from the tipped paper tray on the used rotating shaft to the paper tray frame. At least one of the paper guiding rollers in the used paper guiding assembly is provided with the limiting ring. The spare paper guiding assembly is used to export the tipped paper output from the tipped paper tray on the spare rotating shaft to the paper tray frame. At least one of the paper guiding rollers in the spare paper guiding assembly is provided with the limiting ring.
[0015] In one embodiment, the paper tray holder further includes a flipping mechanism connected to the frame body. The flipping mechanism is used to rotate the frame body to switch the working shaft and the spare shaft to work in sequence.
[0016] In one embodiment, the flipping mechanism includes:
[0017] An electric motor, wherein the output shaft of the electric motor is connected to a first pulley;
[0018] The second pulley is connected to the frame.
[0019] A timing belt, which is fitted onto the first pulley and the second pulley.
[0020] In one embodiment, the paper tray holder is further provided with a photoelectric sensor, which is used to detect the remaining amount of tipping paper in the tipping paper tray.
[0021] Secondly, this application also provides a tipping paper supply device, including the aforementioned paper tray frame.
[0022] In the aforementioned paper tray holder, two limiting rings are set on at least one guide roller, and these two limiting rings are spaced apart along the axial direction of the guide roller, forming a limiting groove between the two limiting rings for accommodating the tipping paper. Thus, when the tipping paper passes through the guide roller, the two limiting rings can limit the tipping paper from both sides of its width, preventing it from swaying along the axial direction of the guide roller during transport. This improves the stability of the tipping paper output from the paper tray holder, avoids defects such as inconsistent tipping paper length, and ensures the quality of the finished cigarettes.

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.

[0034] 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.
[0035] 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.
[0036] 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.

[0037] 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.
[0038] Specifically, one embodiment of this application provides a paper tray holder, which can be used in a tipping paper supply device to support a tipping paper tray and output tipping paper. See also... Figure 1 as well as Figure 2 One embodiment of the paper tray holder includes a frame 10 and a paper guiding assembly. The frame 10 has a rotating shaft 20 for loading tipped paper trays (not shown). The paper guiding assembly includes multiple guide rollers 30, which are spaced apart on the frame 10 and work together to guide the tipped paper from the tray to the paper tray holder. Figure 3 At least one guide roller 30 is provided with two limiting rings 50, which are spaced apart along the axial direction of the guide roller 30, and a limiting groove 301 for accommodating the cork paper is formed between the two limiting rings 50.
[0039] In the aforementioned paper tray holder, two limiting rings 50 are provided on at least one guide roller 30, and the two limiting rings 50 are spaced apart along the axial direction of the guide roller 30, so that a limiting groove 301 for accommodating the tipping paper is formed between the two limiting rings 50. Thus, when the tipping paper passes through the guide roller 30, the two limiting rings 50 can limit the tipping paper from both sides of its width, preventing the tipping paper from swaying along the axial direction of the guide roller 30 during transport. This improves the stability of the tipping paper output from the paper tray holder, avoids defects such as inconsistent tipping paper length, and ensures the quality of the finished cigarette.
[0040] For example, such as Figure 1As shown, in one embodiment, the paper guiding assembly includes five paper guiding rollers 30, one of which is provided with a limiting ring 50, thereby limiting the position of the tipping paper while controlling costs. Understandably, in other embodiments, the number of paper guiding rollers 30 may be more or fewer, and this is not limited thereto.
[0041] For example, in other embodiments, all guide rollers 30 may be provided with limiting rings 50 to further improve the limiting effect on the tipping paper.
[0042] For example, the limiting ring 50 is detachably connected to the guide roller 30, and the position of the limiting ring 50 in the axial direction of the guide roller 30 is adjustable. In this way, the distance between the two limiting rings 50 can be flexibly adjusted according to the width of the tipping paper, so that the paper tray can be adapted to tipping paper of different widths, thereby improving the applicability of the paper tray.
[0043] Specifically, see Figure 4 In one embodiment, a threaded hole 52 is provided through the outer peripheral surface of the limiting ring 50. The paper tray holder also includes a threaded connector (not shown), which is threaded into the threaded hole 52 and abuts against the guide roller 30 to lock the limiting ring 50 in the guide roller 30. Thus, the axial position of the limiting ring 50 in the guide roller 30 can be adjusted by loosening the threaded connector. Preferably, a plurality of threaded holes 52 are provided on the outer peripheral surface of the limiting ring 50. The threaded holes 52 are spaced apart circumferentially along the limiting ring 50, and a threaded connector passes through each threaded hole 52. The threaded connector can be a countersunk screw.
[0044] See Figure 3 Both limiting rings 50 have chamfers 51 on their opposite sides. The opposite sides of the two limiting rings 50 refer to the side of the limiting ring 50 closer to the other limiting ring 50. By providing chamfers 51 on the opposite sides of both limiting rings 50, when the tipping paper shifts, the chamfers 51 can guide the tipping paper back into the limiting groove 301, thereby correcting the shift of the tipping paper.
[0045] See Figure 1 For example, in one embodiment, the frame 10 includes a frame body 11 and a tensioning arm 12, the tensioning arm 12 being movably connected to the frame body 11, one of the paper guide rollers 30 in the paper guide assembly being disposed on the tensioning arm 12, and the other paper guide rollers 30 being disposed on the frame body 11.
[0046] Furthermore, the guide roller 30 located on the tensioning arm 12 is provided with a limiting ring 50. The guide roller 30 on the tensioning arm 12 is used to tension the tipping paper, thereby ensuring that the tipping paper remains taut during transport and preventing paper jams. At the same time, since the guide roller 30 on the tensioning arm 12 can always abut against the tipping paper, the limiting ring 50 on the guide roller 30 can improve the stability of limiting the tipping paper.
[0047] See Figure 1 In one embodiment, there are two rotating shafts 20, namely a used rotating shaft 21 and a spare rotating shaft 22, which are arranged alternately on the frame 10. There are also two paper guiding assemblies, namely a used paper guiding assembly 31 and a spare paper guiding assembly 32. The used paper guiding assembly 31 is used to guide the tipped paper output from the tipped paper tray on the used rotating shaft 21 to the paper tray frame, and at least one guide roller 30 in the used paper guiding assembly 31 is provided with a limiting ring 50. The spare paper guiding assembly 32 is used to guide the tipped paper output from the tipped paper tray on the spare rotating shaft 22 to the paper tray frame, and at least one guide roller 30 in the spare paper guiding assembly 32 is provided with a limiting ring 50.
[0048] Specifically, the active shaft 21 and the spare shaft 22 can be switched in turn. In other words, when the tipping paper tray on the active shaft 21 is used up, the output of tipping paper is switched to the tipping paper tray on the spare shaft 22. At this time, a new tipping paper tray is installed on the active shaft 21. By repeating this cycle, the output of tipping paper can be achieved without interruption.
[0049] See Figure 2 In one embodiment, the paper tray holder further includes a flipping mechanism 40, which is connected to the frame 10. The flipping mechanism 40 is used to rotate the frame 10 to switch the operation of the in-use rotating shaft 21 and the spare rotating shaft 22 in sequence. Specifically, as shown... Figure 2 As shown, the upper rotating shaft 20 enters the working state, while the lower rotating shaft 20 enters the standby state. The frame 10 is driven to rotate 180° by the flipping mechanism 40 to switch the upper and lower positions of the two rotating shafts 20, thereby switching the working state of the two rotating shafts 20.
[0050] Optionally, in one embodiment, the flipping mechanism 40 includes a motor 41, a first pulley 42, a second pulley 44, and a synchronous belt 43. The output shaft of the motor 41 is connected to the first pulley 42. The second pulley 44 is connected to the frame 10, and the synchronous belt 43 is fitted between the first pulley 42 and the second pulley 44. Thus, by driving the first pulley 42 to rotate via the motor 41, and the first pulley 42 driving the second pulley 44 and the frame 10 to rotate via the synchronous belt 43, the working states of the two rotating shafts 20 can be switched.
[0051] See Figure 2The paper tray holder is also equipped with a photoelectric sensor 60, which is used to detect the remaining amount of tipping paper in the tipping paper tray. Specifically, the photoelectric sensor 60 can receive the light beam from the reflector on the back of the rotating shaft 20 and generate pulses. When the tipping paper on the tipping paper tray is gradually used up, the rotation speed of the rotating shaft 20 increases, and the frequency of the reflected light beam received by the photoelectric sensor also increases. When the set value is reached, it can be determined that the remaining amount of tipping paper in the tipping paper tray is insufficient. At this time, the flipping mechanism 40 rotates the frame 10, switching the spare rotating shaft 22 located below to the top, so that it enters the working state. At the same time, it notifies the worker or automated equipment to install a new tipping paper tray onto the rotating shaft 20 below to replace the tipping paper tray with insufficient remaining amount.
[0052] This application also provides a tipping paper supply device. Specifically, one embodiment of the tipping paper supply device includes a paper tray frame of any of the above embodiments.
[0053] In the aforementioned tipping paper supply device, the paper tray frame has two limiting rings 50 on at least one guide roller 30, and the two limiting rings 50 are spaced apart along the axial direction of the guide roller 30, so that a limiting groove 301 for accommodating the tipping paper is formed between the two limiting rings 50. Thus, when the tipping paper passes through the guide roller 30, the two limiting rings 50 can effectively limit it from both sides of the width of the tipping paper, preventing the tipping paper from swaying along the axial direction of the guide roller 30 during conveying. This improves the stability of the tipping paper output from the paper tray frame, avoids defects such as inconsistent lengths of the tipping paper, and ensures the quality of the finished cigarette.
[0054] 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.
[0055] The embodiments described above are merely illustrative of 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.
