Detailed Implementation

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] In related technologies, due to actual production needs, the ZJ118 winding and splicing machine needs to be configured with other external equipment for joint production when producing or trial-producing certain products (the following example is the configuration of a fragrance applicator). When the ZJ118 winding and splicing machine is configured with a fragrance applicator, it is necessary to obtain the operating speed of the winding and splicing machine and transmit it to the fragrance applicator in real time. The fragrance applicator then matches the amount of fragrance sprayed onto the paper rolls according to the operating speed of the winding and splicing machine.

[0051] However, the ZJ118 winding and splicing machine was not equipped with relevant components to obtain the machine's operating speed when it left the factory, and the structure of the winding and splicing machine does not support the direct installation and linkage of the fragrance adding machine. As a result, it is not easy for the ZJ118 winding and splicing machine and the fragrance adding machine to be linked for production, which cannot meet the current production needs of diversified and innovative products.

[0052] To address the aforementioned issues, embodiments of this application provide a rotation speed acquisition component and a winding and splicing device, which can reduce the difficulty of coordinated production between the winding and splicing machine and other external equipment.

[0053] The following will combine Figures 1-11 The rotation speed acquisition component and winding device provided in the embodiments of this application will be described.

[0054] See Figure 1 and Figure 2 This application provides a winding and splicing device, which includes a winding and splicing machine 200 and a rotation speed acquisition component 100. The rotation speed acquisition component 100 is used to acquire the rotation speed of the rotation shaft 210 of the winding and splicing machine 200.

[0055] In some embodiments, the rotating shaft 210 may be the main drive shaft of the coiling machine 200.

[0056] In some embodiments, the coiling machine 200 can be a ZJ118 type coiling machine.

[0057] The following describes the rotation speed acquisition component 100 provided in the embodiments of this application.

[0058] See Figure 2 This application provides a rotation speed acquisition component 100, which includes a base 140, a connecting plate 150, and a rotation speed acquisition element 130. The connecting plate 150 is detachably connected to the base 140, and the rotation speed acquisition element 130 is mounted on the connecting plate 150. The rotation speed acquisition element 130 is used to acquire the rotation speed of the rotating shaft 210 of the winding and splicing machine 200. Thus, by setting the rotation speed acquisition element 130, when the winding and splicing machine 200 is equipped with external equipment (e.g., a fragrance application machine), the operating speed of the winding and splicing machine 200 can be acquired. The rotation speed acquisition component 100 can obtain accurate speed information of the winding and splicing machine 200 and transmit it to the fragrance application machine in real time. The fragrance application machine matches the amount of fragrance sprayed onto the roll paper according to the operating speed of the winding and splicing machine 200, thereby reducing the difficulty of coordinated production between the winding and splicing machine 200 and the fragrance application machine, and meeting the production needs of current diversified and innovative products.

[0059] In some embodiments, the rotation speed acquisition component 130 can be a shaft encoder. A shaft encoder is a sensor used to measure the position, angle, speed, or acceleration of a rotating shaft. Its core function is to convert mechanical rotational motion into electrical signals that can be recognized by electronic devices (such as controllers, PLCs, microcontrollers, etc.), thereby achieving accurate monitoring and control of rotational motion.

[0060] In some embodiments, the rotational speed of the rotating shaft 210 of the winding machine 200 may include at least one of the angular velocity (the angle through which the rotating shaft 210 rotates per unit time) and the rotational speed (the number of revolutions the rotating shaft 210 makes per unit time).

[0061] See Figure 2 and Figure 3 The rotation speed acquisition component 100 includes a first positioning member 110 and a second positioning member 120. The first positioning member 110 is located on one side of the connecting plate 150 along a first direction, and the second positioning member 120 is located on one side of the connecting plate 150 along a second direction. When the first positioning member 110 is in the adjustment state, it is movably configured relative to the base 140 along the first direction X. When the first positioning member 110 is in the positioning state, it abuts against one side of the connecting plate 150 along the first direction X and is connected to the base. Thus, the position of the connecting plate 150 along the first direction X can be adjusted as needed, and the position of the connecting plate 150 along the first direction X can be defined after adjustment. When the second positioning member 120 is in the adjustment state, it is movable relative to the base 140 along the second direction Y. When the second positioning member 120 is in the positioning state, it abuts against one side of the connecting plate 150 along the second direction Y and is connected to the base. This allows the position of the connecting plate 150 along the second direction Y to be adjusted as needed, and then its position is fixed after adjustment. The arrangement of the first positioning member 110 and the second positioning member 120 makes the assembly and disassembly of parts such as the connecting plate 150 and the rotation speed acquisition member 130 extremely convenient, facilitating actions such as replacing the coupling 160.

[0062] For example, any two of the first direction X, the second direction Y, and the third direction Z can intersect, for example, they can intersect obliquely or perpendicularly.

[0063] For example, the third direction Z may be parallel to the axis of at least one of the rotating shaft 210, coupling 160 and connecting shaft 180.

[0064] For example, the second direction Y can be parallel to the direction of gravity.

[0065] In some embodiments, see Figure 2 , Figure 4 and Figure 10The rotation speed acquisition component 100 includes multiple first fastening components, each including a first stud and a first nut. The first positioning member 110 is provided with multiple first adjustment holes 111 spaced apart along the second direction Y, and the first adjustment holes 111 extend along the first direction X. The base 140 is provided with multiple first through holes 1411, and any two of the first adjustment holes 111, first through holes 1411, and first fastening components are correspondingly provided. In the corresponding first adjustment holes 111, first through holes 1411, and first fastening components, the first nut is located on the side of the base 140 away from the first positioning member 110, the shank of the first stud passes through the first adjustment holes 111, first through holes 1411, and first nut, and the shank of the first stud is threadedly connected to the first nut. The head of the first stud is located on the side of the first positioning member 110 away from the base 140. Thus, by tightening the first nut, the first positioning member 110 is positioned, and the first stud and the first nut fix the first positioning member 110 to the base 140. Alternatively, by loosening the first nut, the first positioning member 110 is adjusted. Since the first adjustment hole 111 is an elongated hole extending along the first direction X, the first positioning member 110 can move relative to the first stud along the first direction X through the cooperation of the first adjustment hole 111 and the first stud, thereby adjusting the position of the first positioning member 110 relative to the base 140. Then, the connecting plate 150 is pressed tightly against the first positioning member 110, and the position of the connecting plate 150 along the first direction X is adjusted as needed.

[0066] It should be noted that the shank of the first stud and the first through hole can be clearance-fitted, facilitating the insertion of the shank into the first through hole. The size of the first through hole is slightly larger than that of the shank of the first stud, allowing for some movement of the shank within the first through hole. The shank of the second stud and the second through hole, the shank of the third stud and the third through hole, and the shank of the fourth stud and the fourth through hole can all be clearance-fitted. Any one of the first, second, third, and fourth studs can be a bolt or a screw. Taking the first stud as an example, the outer diameter of the shank is smaller than the outer diameter of the head, and the outer wall of the shank of the first stud has threads.

[0067] In some embodiments, see Figure 2 , Figure 5 and Figure 10The rotation speed acquisition component 100 includes multiple second fastening components, each including a second stud and a second nut. The second positioning member 120 is provided with multiple second adjustment holes 122 spaced apart along a first direction X, extending along a second direction Y. The base 140 is provided with multiple second through holes 1412, and any two of the second adjustment holes 122, second through holes 1412, and second fastening components are correspondingly provided. In the corresponding second adjustment hole 122, second through hole 1412, and second fastening component, the second nut is located on the side of the base 140 opposite to the second positioning member 120. The shank of the second stud passes through the second adjustment hole 122, second through hole 1412, and second nut, and the shank of the second stud is threadedly connected to the second nut. The head of the second stud is located on the side of the second positioning member 120 opposite to the base 140. Thus, by tightening the second nut, the second positioning member 120 is positioned, and the second stud and the second nut fix the second positioning member 120 to the base 140. Alternatively, by loosening the second nut, the second positioning member 120 can be adjusted. Since the second adjustment hole 122 is an elongated hole extending along the second direction Y, the second positioning member 120 can move relative to the second stud along the second direction Y through the cooperation of the second adjustment hole 122 and the second stud, thereby adjusting the position of the second positioning member 120 relative to the base 140. Then, the connecting plate 150 is pressed tightly against the second positioning member 120, and the position of the connecting plate 150 along the second direction Y can be adjusted as needed.

[0068] In some embodiments, see Figure 2 , Figures 6-9The rotation speed acquisition component 100 includes a coupling 160, a calibration fixture 170, and a connecting shaft 180. One end of the connecting shaft 180 is coaxially connected to the rotation shaft 210 of the coiling machine 200. The stiffness of the coupling 160 is less than that of the calibration fixture 170. The calibration fixture 170 has a first connecting hole 171 and a second connecting hole 172 at both ends, and the coupling 160 has a third connecting hole 163 and a fourth connecting hole 164 at both ends. The rotation speed acquisition component 100 is configured such that, when the connecting shaft 180 and the rotation speed acquisition component 130 are in a calibration state, the input shaft 131 of the connecting shaft 180 and the rotation speed acquisition component 130 are coaxially connected through the calibration fixture 170. In the calibration state, the input shaft 131 of the rotation speed acquisition component 130 passes through the first connecting hole 171, and the rotation speed acquisition component 130 is coaxially connected to the calibration fixture 170. The other end of the connecting shaft 180 passes through the second connecting hole 172, and the connecting shaft 180 is coaxially connected to the calibration fixture 170. In the assembled state, the input shaft 131 of the connecting shaft 180 and the rotation speed acquisition component 130 is coaxially connected through the coupling 160. In the assembled state, the input shaft 131 of the rotation speed acquisition component 130 passes through the third connecting hole 163, and the input shaft 131 of the rotation speed acquisition component 130 is coaxially connected to the coupling 160. The other end of the connecting shaft 180 passes through the fourth connecting hole 164, and the connecting shaft 180 is coaxially connected to the coupling 160. Thus, the calibration fixture 170 has greater rigidity, and by first using the calibration fixture 170 to calibrate the coaxiality of the connecting shaft 180 and the rotation speed acquisition component 130, the connecting shaft 180 and the input shaft 131 of the rotation speed acquisition component 130 can achieve higher coaxiality after being assembled by the coupling 160, thereby extending the service life of the coupling 160.

[0069] Stiffness refers to the ability of a material or structure to resist elastic deformation when subjected to force, and it is a characterization of the ease with which a material or structure undergoes elastic deformation.

[0070] In some embodiments, the coupling 160 is also provided with a set screw hole 161. The set screw can be used to fix the coupling 160 at the fourth connection hole 164 to the output end 181 of the connecting shaft 180 through the set screw hole 161, so as to ensure that the connecting shaft 180 accurately transmits the rotational speed to the coupling 160.

[0071] It should be noted that the rotation speed acquisition component 100 requires the connecting shaft 180 and the input shaft 131 of the rotation speed acquisition component 130 (taking a shaft encoder as an example) to have the highest possible coaxiality, which can improve the service life of the coupling 160. However, due to the relatively low rigidity of the coupling 160 and its ductility and compressibility in all directions, directly using the coupling 160 for the alignment connection between the connecting shaft 180 and the input shaft 131 of the shaft encoder will adversely affect the coaxiality of the connecting shaft 180 and the input shaft 131 of the shaft encoder. Therefore, a calibration fixture 170 is designed with connecting holes of the same shape and size as the coupling 160. The overall rigidity of the calibration fixture 170 is much higher than that of the coupling 160, and it is used for the initial installation of the rotation speed acquisition component 100. During initial installation, calibration fixture 170 is used instead of coupling 160 to more accurately determine the position of each part, resulting in better coaxiality after subsequent assembly of connecting shaft 180 and input shaft 131 of shaft encoder, thereby extending the service life of coupling 160.

[0072] In some embodiments, see Figure 2 After installation using calibration fixture 170 instead of coupling 160, the first positioning member 110 is brought close to the vertical edge of the connecting plate 150 along the first direction X (e.g., the left side). The first positioning member 110 is then fixed to the base 140 using a first stud and a first nut through the first through hole 1411 and the first adjusting hole 111. This achieves positioning of the connecting plate 150 in the first direction X (e.g., laterally). Additionally, the second positioning member 120 is brought close to the horizontal edge of the connecting plate 150 along the second direction Y (e.g., the lower side). The second positioning member 120 is then fixed to the base 140 using a second stud and a second nut through the second through hole 1412 and the second adjusting hole 122. This achieves positioning of the connecting plate 150 in the second direction Y (e.g., longitudinally).

[0073] In some embodiments, after the lateral and longitudinal positioning of the connecting plate 150 is achieved, the connecting plate 150 can be disassembled and the calibration fixture 170 can be replaced with the coupling 160. At this time, there is no need to recalibrate the position of the connecting plate 150. The connecting plate 150 can be directly pressed against the second positioning member 120 and the first positioning member 110, and the connecting plate 150 can be fixed to the base 140 using the fourth stud and the fourth nut.

[0074] For example, see Figure 7 The coupling 160 can be a flexible coupling, and the portion of the coupling 160 located between the third connecting hole 163 and the fourth connecting hole 164 can be flexible.

[0075] For example, the calibration fixture 170 is cylindrical in shape.

[0076] In some embodiments, see Figure 8 The connecting shaft 180 may include a threaded section at one end, an output end 181 at the other end, and a disassembly / assembly section connecting the output end 181 and the threaded section. The threaded section of the connecting shaft 180 can be used to replace the screws on the main drive shaft of the coiling machine, allowing the connecting shaft 180 to secure the main drive shaft while achieving the same rotational speed as the main drive shaft. The disassembly / assembly section is designed as a regular hexagonal prism to facilitate the installation, tightening, or disassembly of the connecting shaft 180 using an external hex wrench. The diameter of the output end 181 is designed to be equal to that of the fourth connecting hole 164 to facilitate a tight connection with the coupling 160.

[0077] In some embodiments, see Figure 1 and Figure 10 The base 140 includes a first sub-base 141 and a second sub-base 142 whose extending directions intersect. The first sub-base 141 and the second sub-base 142 are arranged along a second direction Y and are connected to each other. The connecting plate 150, the first positioning member 110, and the second positioning member 120 are all mounted on the first sub-base 141. The second sub-base 142 is used to connect with the machine platform 220 of the winding and splicing machine 200. In this way, by setting the extending directions of the first sub-base 141 and the second sub-base 142 to intersect, it is beneficial to reduce the volume of the base 140 and increase the area where the base 140 is connected to the machine platform 220.

[0078] For example, the base 140 is located on the top side of the body platform 220.

[0079] In some embodiments, see Figure 1 , Figure 2 and Figure 10The rotation speed acquisition component 100 includes multiple third fastening components, each including a third stud and a third nut. The second sub-base 142 is provided with multiple third adjustment holes 1423 spaced apart along a first direction X, and the third adjustment holes 1423 extend along a third direction Z. The body platform 220 is provided with multiple third through holes. Any two of the third adjustment holes 1423, third through holes, and third fastening components are correspondingly provided. In the corresponding third adjustment holes 1423, third through holes, and third fastening components, the third nut is located on the side of the body platform 220 away from the second sub-base 142. The shank of the third stud passes through the third adjustment hole 1423, the third through hole, and the third nut, and the shank of the third stud is threadedly connected to the third nut. The head of the third stud is located on the side of the second sub-base 142 away from the body platform 220, meaning the body platform 220 and the second sub-base 142 are sandwiched between the head of the third stud and the third nut. Thus, by tightening the third nut, the third stud and the third nut can fix the base 140 onto the machine platform 220. Alternatively, by loosening the third nut, since the third adjustment hole 1423 is an elongated hole extending along the third direction Z, the base 140 can move relative to the third stud along the third direction Z through the cooperation of the third adjustment hole 1423 and the third stud. This allows the position of the base 140 relative to the machine platform 220 to be adjusted, and the rotation speed can be adjusted as needed to obtain the position of the component 100 along the third direction Z, so that it can better cooperate with the winding and splicing machine 200.

[0080] In some embodiments, see Figure 2 , Figure 10 and Figure 11The rotation speed acquisition component 100 includes multiple fourth fastening components, each including a fourth stud and a fourth nut. The connecting plate 150 is provided with multiple fourth adjustment holes 154 spaced apart along a first direction X, extending along a second direction Y. The first sub-base 141 is provided with multiple fourth through holes 1414. Any two of the fourth adjustment holes 154, fourth through holes 1414, and fourth fastening components are correspondingly provided. In the corresponding fourth adjustment holes 154, fourth through holes 1414, and fourth fastening components, the fourth nut is located on the side of the first sub-base 141 away from the connecting plate 150. The shank of the fourth stud passes through the fourth adjustment holes 154, fourth through holes 1414, and fourth nut, and the shank of the fourth stud is threadedly connected to the fourth nut. The head of the fourth stud is located on the side of the connecting plate 150 away from the first sub-base 141. Thus, by tightening the fourth nut, the fourth stud and the fourth nut can fix the connecting plate 150 onto the base 140. Alternatively, by loosening the fourth nut, since the fourth adjusting hole 154 is an elongated hole extending along the second direction Y, the connecting plate 150 can move relative to the fourth stud along the second direction Y through the cooperation of the fourth adjusting hole 154 and the fourth stud. This allows the height of the connecting plate 150 relative to the base 140 to be adjusted, thereby adjusting the height of the rotation speed acquisition component 130, the coupling 160, and the connecting shaft 180 as needed.

[0081] In some embodiments, the connecting plate 150 has a plurality of protrusions spaced apart on the side facing the second positioning member 120, and the plurality of protrusions are arranged at intervals along the first direction. The second positioning member 120 has a plurality of limiting grooves spaced apart on the side facing the connecting plate 150, and the plurality of limiting grooves are arranged at intervals along the first direction X. The limiting grooves and protrusions are correspondingly provided. The protrusions are located in the corresponding limiting grooves, and the protrusions and the sidewalls of the limiting grooves on both sides along the first direction X at least partially abut against each other. In this way, through the cooperation of the protrusions and the limiting grooves, the second positioning member 120 and the connecting plate 150 can be assembled as a whole. The second positioning member 120 can increase the connection area between the connecting plate 150 and the base 140 to a certain extent, and improve the connection stability between the connecting plate 150 and the base 140. In addition, the second positioning member 120 can also position the connecting plate 150 on both sides along the first direction X. Compared with only setting the first positioning member 110 to position the connecting plate 150 on one side along the first direction X, the second positioning member 120 can better position the connecting plate 150.

[0082] It should be noted that, see Figure 2 , Figure 5 , Figure 10 and Figure 11The second adjusting hole 122 and the fourth adjusting hole 154 can be two holes of the same shape and size. The second adjusting hole 122 and the fourth adjusting hole 154 having the same size means, at least, that the second adjusting hole 122 and the fourth adjusting hole 154 have the same size along the first direction X and the same size along the second direction Y. The second through hole 1412 and the fourth through hole 1414 can be holes of the same shape and size. The second screw and the fourth screw can be screws of the same shape and size. Thus, when the second nut and the fourth nut are loosened, the second positioning member 120 and the connecting plate 150 can move the same distance along the first direction X and the same distance along the second direction Y, allowing the second positioning member 120 and the connecting plate 150 to move synchronously as a whole along the first direction X and the second direction Y.

[0083] In some embodiments, the shape of the limiting groove matches the shape of the protrusion, meaning the shapes of the limiting groove and the protrusion are identical, allowing each wall of the limiting groove to make good contact with the outer wall of the protrusion. The limiting groove includes a first sub-limiting groove and a second sub-limiting groove that are connected. The first sub-limiting groove is located between the second sub-limiting groove and the connecting plate 150, and the dimension of the first sub-limiting groove along the first direction X is larger than the dimension of the second sub-limiting groove along the first direction X. The protrusion includes a first sub-protrusion and a second sub-protrusion that are connected. The first sub-protrusion is located between the second sub-protrusion and the connecting plate 150, and both the first and second sub-protrusions are located within the first and second sub-limiting grooves. The dimension of the first sub-protrusion along the first direction X is larger than the dimension of the second sub-protrusion along the first direction X. Thus, setting the dimension of the first sub-limiting groove along the first direction X to be larger than the dimension of the first sub-protrusion along the first direction X makes it easier for the protrusion to be inserted into the limiting groove, reducing the difficulty of inserting the protrusion.

[0084] In some embodiments, the size of the first sub-limiting groove along the first direction X gradually increases from the second sub-limiting groove to the first sub-limiting groove. In this way, the groove sidewalls on both sides of the first sub-limiting groove along the first direction X can serve as guide walls, allowing the protrusion to slide into the limiting groove along the guide walls, further reducing the difficulty of inserting the protrusion.

[0085] In some embodiments, the dimensions of the second sub-protrusions of the plurality of protrusions along the first direction X increase sequentially from the first positioning member 110 to the connecting plate 150. Thus, since the first positioning member 110 is not provided on the side of the connecting plate 150 away from the first positioning member 110, the winding machine 200 experiences mechanical vibration during operation. This mechanical vibration is transmitted to the plurality of protrusions and exerts a force on them. The first positioning member 110 can share part of the force, thereby reducing the force on a number of protrusions close to the first positioning member 110, while a number of protrusions far from the first positioning member 110 are subjected to a larger force and are more prone to deformation. By setting the size of the protrusions far from the first positioning member 110 to be larger, mechanical vibration can be prevented from damaging the protrusions.

[0086] In some embodiments, the contact interface between the connecting plate and the first positioning member is planar.

[0087] In some embodiments, see Figure 2 , Figure 6 , Figure 7 and Figure 11 The shaft encoder is mounted on the connecting plate 150 using screws through three circumferentially evenly distributed fifth through holes 155 and threaded holes 132 of the shaft encoder. The input shaft 131 of the shaft encoder passes through the body hole 153 on the connecting plate 150 and connects to the third connecting hole 163 of the coupling 160. A set screw is used to fix the coupling 160 at the third connecting hole 163 to the input shaft 131 of the shaft encoder through another set hole 161, ensuring that the coupling 160 accurately transmits the rotational speed to the shaft encoder. The connecting shaft 180 is connected to the shaft encoder through the coupling 160 and accurately transmits the speed of the coiling machine 200 to the shaft encoder through the coupling 160. Therefore, external equipment such as the incense dispenser can connect to the shaft encoder to obtain the speed information of the coiling machine 200 and coordinate with the coiling machine 200 for production activities.

[0088] In summary, in this embodiment, the shaft encoder is mounted on the connecting plate 150, and the connecting plate 150 is positioned by the first positioning member 110 and the second positioning member 120. The connecting plate 150, the first positioning member 110, and the second positioning member 120 are mounted on the base 140 by studs. The base 140 is mounted on the machine platform 220. The calibration fixture 170 is used for the initial installation of the device, so that the connecting shaft 180 and the input shaft 131 of the shaft encoder can achieve a high degree of coaxiality, extending the service life of the coupling 160. The setting of the first positioning member 110 and the second positioning member 120 makes the disassembly and assembly of the connecting plate 150, the shaft encoder, and other parts extremely convenient, facilitating actions such as replacing the coupling 160.
