Description

Technical Field

[0001] This application relates to the field of filter rod cross-section detection technology, and in particular to a filter rod cross-section cutting device and a filter rod cross-section detection system. Background Technology

[0002] Cigarette filters are an important component of cigarettes, effectively filtering and trapping harmful substances in cigarette smoke. As consumers' demands for cigarette products become healthier, and as the tobacco industry continues to demand improvements in filter functions such as tar reduction, harm reduction, aroma enhancement, and moisture retention, specialized filter rods have emerged.

[0003] Specialty filter rods are classified according to different structures, including grooved filter rods, coaxial core filter rods, flavor capsule filter rods, and aroma thread filter rods. Specialty filter rods may have inconsistent cross-sectional shapes, leading to defects in the cigarette and affecting its smoking experience. Therefore, generally, the characteristics of one end of the filter rod need to be inspected before it leaves the factory.

[0004] In related technologies, the feature detection of the filter rod cross-section still relies on manually adjusting the relative position of the cutter and the filter rod to cut the filter rod cross-section for subsequent observation.

[0005] However, this cutting method requires constant manual adjustment of the relative position between the cutter and the filter rod, which is extremely inconvenient. Furthermore, due to the design of the cutter, it is easy to cause cuts to people, resulting in poor overall performance of the filter rod cross-section cutting system. Utility Model Content

[0006] Therefore, it is necessary to provide a filter rod cross-section cutting device and a filter rod cross-section detection system to address the problem of poor performance caused by excessive manpower input during the filter rod cross-section cutting process.

[0007] A filter rod cross-section cutting device, the filter rod cross-section cutting device comprising:

[0008] The support assembly is used to support the filter rod;

[0009] The filter rod is provided with a cutting component and a first driving component. The cutting component is used to cut the filter rod. The first driving component is drivenly connected to the cutting component to drive the cutting component to move in a direction perpendicular to the length direction of the filter rod, so as to cut the filter rod.

[0010] The assembly includes a push rod assembly and a second drive assembly. The second drive assembly is driven to the push rod assembly. The push rod assembly is used to drive the filter rod to move relative to the support assembly along the length direction under the drive of the second drive assembly, so as to adjust the cutting position of the cutting assembly on the filter rod.

[0011] In one embodiment, the filter rod section cutting device further includes a clamping component and a third driving component. The third driving component is drivenly connected to the clamping component and is used to drive the clamping component to move in a direction close to or away from the filter rod, so that the clamping component abuts against or releases the filter rod located on the carrying component.

[0012] In one embodiment, the third drive assembly includes a power source and a telescopic rod; one end of the telescopic rod is driven and connected to the power source, and the other end is connected to the clamping assembly; the power source is used to drive the clamping assembly to switch between a first position and a second position via the telescopic rod, wherein when the clamping assembly is in the first position, the clamping assembly holds the filter rod against the bearing assembly; when the clamping assembly is in the second position, the clamping assembly releases its hold on the filter rod.

[0013] In one embodiment, the filter rod section cutting device further includes a control component; the control component is communicatively connected to the first drive component and the second drive component; the control component is used to control the first drive component and the second drive component to drive according to control commands.

[0014] In one embodiment, the filter rod section cutting device further includes a photoelectric sensing component; the photoelectric sensing component is used to detect whether a filter rod exists at the cutting position; the photoelectric sensing component is communicatively connected to the control component; when the photoelectric sensing component does not detect the filter rod, the control component controls the second driving component to drive the push rod component to move, so that the push rod component drives the filter rod to move toward the cutting position.

[0015] In one embodiment, the photoelectric sensing component includes a first photoelectric sensor and a second photoelectric sensor; both the first and second photoelectric sensors are driveably connected to the control component; the filter rod is provided with a first end and a second end opposite to each other; the first photoelectric sensor is used to detect the presence of the first end, and the second photoelectric sensor is used to detect the presence of the second end; when the first photoelectric sensor does not detect the first end, and / or when the second photoelectric sensor detects the second end, the control component controls the second drive component to drive the push rod assembly to move, so that the push rod assembly drives the filter rod to move toward the cutting position.

[0016] In one embodiment, the carrier component is provided with a plurality of limiting grooves, which are matched with the filter rod for limiting.

[0017] In one embodiment, the supporting component includes a limiting member and a guiding member. The limiting member is connected to the side of the guiding member near the cutting component, and the limiting groove is formed at the connection between the limiting member and the guiding member. The guiding member is inclined and is used to guide the filter rod to slide into the limiting groove.

[0018] In one embodiment, the filter rod section cutting device further includes a feeding assembly, which includes a mounting housing and a roller body; the mounting housing is provided with a feeding port, a mounting cavity, and a discharge port at intervals; the edge of the discharge port is connected to the support assembly so that the filter rod can move to the support assembly through the discharge port; the mounting cavity is used to mount the roller body, and the roller body is rotatably disposed on the mounting housing;

[0019] When the roller body is installed in the mounting cavity, the roller body and the feed inlet are spaced apart to form a first gap channel, and the roller body and the discharge inlet are spaced apart to form a second gap channel; the gap width of the first gap channel and the gap width of the second gap channel are both greater than the diameter of the filter rod; wherein, the gap width of at least one of the first gap channel and the second gap channel is less than the sum of the diameters of the two filter rods.

[0020] A filter rod cross-section detection system includes an imaging component, a computing module, and a filter rod cross-section cutting device as described in the above embodiments. The imaging component is disposed opposite to the end of the filter rod away from the top rod component. The imaging component is used to acquire cross-sectional images of the filter rod. The computing module is communicatively connected to the imaging component to receive the cross-sectional images. The computing module determines the finished quality of the filter rod based on the cross-sectional images.

[0021] The aforementioned filter rod cutting device and filter rod cross-section detection system are driven by a first driving component connected to a cutting component. This allows the cutting component to flexibly adjust its position according to the width of the filter rod to be cut, thereby achieving precise cutting of the filter rod in a direction perpendicular to its length. Furthermore, the second driving component is driven by a top rod component, enabling the cross-section to be inspected on the filter rod to be lifted and moved along its length to a position where it can be cut by the cutting component. This improves cutting accuracy and eliminates the need for manual adjustment of the filter rod's positioning, reducing labor costs. In addition, it reduces the risk of cuts to operators from the cutting component, improving the overall performance of the filter rod cross-section cutting device and the filter rod cross-section detection system.

[0031] 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.

[0032] See Figure 1 The filter rod cross-section detection system 10 provided in one embodiment of this application includes a filter rod cross-section cutting device 100 and an imaging component 200.

[0033] Specifically, such as Figure 1 as well as Figure 2 As shown, the filter rod section cutting device 100 includes a supporting component 110, a cutting module 120, and a positioning adjustment module 130. The cutting module 120 includes a cutting component 121 and a first driving component 122. The positioning adjustment module 130 includes a push rod component 131 and a second driving component 132. The supporting component 110 is used to support the filter rod 400. The cutting component 121 is used to cut the filter rod 400. The cutting component 121 can be, but is not limited to, a circular blade assembly, a rotating blade assembly, etc., and is not subject to excessive limitations in this embodiment.

[0034] The cutting component 121 is connected to the first driving component 122. The cutting component 121 is used to move along a direction perpendicular to the length direction X of the filter rod 400 under the drive of the first driving component 122, so as to cut the filter rod 400.

[0035] The push rod assembly 131 is connected to the second drive assembly 132. The push rod assembly 131 is used to drive the filter rod 400 to move relative to the support assembly 110 along the length direction X of the filter rod 400 under the drive of the second drive assembly 132, so as to adjust the cutting position of the cutting assembly 121 on the filter rod 400.

[0036] The filter rod section cutting device 100 of this application is driven to the cutting component 121 via a first driving component 122. This allows the cutting component 121 to be flexibly adjusted according to the width and position of the filter rod 400 to be cut, thereby achieving precise cutting of the filter rod 400 in the direction perpendicular to the length direction X. Furthermore, the second driving component 132 is driven to the top rod component 131, enabling the section to be inspected on the filter rod 400 to be lifted and moved in the length direction X to a position where it can be cut by the cutting component 121, improving cutting accuracy. This improves cutting accuracy without requiring manual adjustment of the filter rod 400's positioning, reducing labor costs. In addition, it reduces the risk of cuts to operators from the cutting component 121, improving the overall performance of the filter rod section cutting device 100.

[0037] For ease of understanding, the following description will use the load-bearing component 110 as a reference to further explain the setting of the relevant structures, but this does not mean that the spatial setting of each structure is limited to this.

[0038] For example, in some implementations, with Figure 1 The filter rod section cutting device 100 shown is arranged in a three-dimensional coordinate system as an example. X, Y, and Z represent the length direction, radial direction (which can also be understood as the direction perpendicular to the length direction), and height direction of the filter rod 400, respectively. That is, the length direction of the filter rod 400 is defined as X, the radial direction as Y, and the height direction as Z. It should be noted that the length direction X, radial direction Y, and height direction Z of the filter rod 400 are only for the convenience of understanding the positional relationship of each structure and the movement direction of the motion mechanism. They do not indicate the dimensional relationship of the filter rod section cutting device 100 in the length direction X and the radial direction Y. In other words, the dimension of the filter rod section cutting device 100 in the length direction X can be greater than, less than, or equal to the dimension in the radial direction Y. No specific limitation is made here.

[0039] The cutting assembly 121 is used to cut the filter rod 400 by moving along the radial direction Y of the filter rod 400 under the drive of the first driving assembly 122. Figure 1 As shown, in one example, the length direction X of the filter rod 400 is consistent with the length direction of the support component 110. In another example, the radial direction Y of the filter rod 400 is consistent with the width direction of the support component 110. In yet another example, the height direction Z of the filter rod 400 is consistent with the height direction of the support component 110.

[0040] Based on this, the first driving component 122 can drive the cutting component 121 to move in the radial direction Y of the filter rod. That is, the first driving component 122 is used to drive the cutting component 121 to move in the radial direction Y of the filter rod 400. Therefore, with this structural arrangement, the position of the cutting component 121 relative to the filter rod 400 in the radial direction Y is adjustable, and the filter rod 400 can be cut. Since the direction in which the cutting component 121 cuts the filter rod 400 is the radial direction of the filter rod 400 (that is, perpendicular to the length direction of the filter rod 400), this operation of cutting the filter rod 400 can also be called "radial cutting". In the embodiments of this application, based on the need to detect the cross section of the filter rod 400, the cutting of the filter rod 400 by the cutting component 121 in the following text is all radial cutting.

[0041] Accordingly, the second drive assembly 132 is driven to connect with the push rod assembly 131. The push rod assembly 131 is used to drive the filter rod 400 to move relative to the support assembly 110 along the length direction X under the drive of the second drive assembly 132, so that the push rod assembly 131 can be driven to lift and cooperate with the filter rod 400 along the length direction X of the filter rod 400, thereby adjusting the cutting position of the cutting assembly 121 relative to the filter rod 400 in the length direction X.

[0042] The imaging component 200 is positioned opposite the end of the filter rod 400 furthest from the top rod assembly 131. The imaging component 200 is used to acquire cross-sectional images of the filter rod 400. The calculation module 300 is communicatively connected to the imaging component 200 to receive the cross-sectional images. The calculation module 300 determines the finished quality of the filter rod 400 based on the cross-sectional images.

[0043] To facilitate understanding, the following explanation will focus on the usage of the filter rod cross-section cutting device 100 in an implementation scenario.

[0044] First, such as Figure 3 As shown, the filter rod 400 is placed on the support component 110, which supports and fixes the filter rod 400, thus improving the stability of the filter rod 400 during the cutting process.

[0045] Secondly, the drive push rod assembly 131 of the second drive assembly 132 moves along the length direction X of the filter rod 400 and engages with the filter rod 400, so that the section to be detected on the filter rod 400 can move in the length direction X to a position that engages with the cutting assembly 121 for cutting.

[0046] Finally, as Figure 4As shown, the first driving component 122 is driven to connect with the cutting component 121, which drives the cutting component 121 to move along the radial direction Y of the filter rod 400. This allows the cutting component 121 to be flexibly adjusted according to the radial position of the filter rod 400 to be cut, thereby achieving precise radial cutting of the filter rod 400 in the radial direction Y.

[0047] Thus, by driving the first drive assembly 122 to the cutting assembly 121, the cutting assembly 121 can be flexibly adjusted according to the width and position of the filter rod 400 to be cut, thereby achieving precise cutting of the filter rod 400 in the radial direction Y. Furthermore, by driving the second drive assembly 132 to the push rod assembly 131, the cross-section to be inspected on the filter rod 400 can be moved by the push rod assembly 131 in the length direction X to a position where it can be cut and matched by the cutting assembly 121, improving cutting accuracy. This achieves improved cutting accuracy without requiring manual adjustment of the filter rod 400's positioning, reducing labor costs. In addition, it reduces the risk of cuts to operators from the cutting assembly 121, improving the performance of the filter rod cross-section cutting device 100 and the filter rod cross-section detection system 10.

[0048] Furthermore, in some embodiments, see back Figure 2 The filter rod section cutting device 100 also includes a control component 140. The control component 140 is communicatively connected to the first drive component 122 and the second drive component 132. The control component 140 is used to control the first drive component 122 and the second drive component 132 to drive according to control commands.

[0049] The control component 140 can be a component capable of performing control functions. Specifically, the control component 140 can be a programmable logic controller (PLC) or a microcontroller. Furthermore, the control instructions can be logical instructions implemented through internal programming, or they can be remotely output by the control component 140 through communication connections with other external devices (such as mobile phones, external computers, etc.). This embodiment does not impose numerous limitations. In one example, the control component 140 can communicate with a computing component to achieve integrated intelligent management of the filter rod cross-section detection system 10.

[0050] Thus, by controlling the first drive component 122 and the second drive component 132 according to the control command, the first drive component 122 and the second drive component 132 can be driven without manual control, thus realizing the intelligent cutting process of the filter rod section cutting device 100.

[0051] Optionally, in one embodiment, combined with Figure 3 as well as Figure 5As shown, the filter rod section cutting device 100 also includes a clamping module 150. The clamping module 150 includes a clamping component 151 and a third drive component 152, which is drivenly connected to the clamping component 151. The third drive component 152 drives the clamping component 151 to move along the height direction Z of the filter rod 400. The clamping component 151 engages with the filter rod 400 in a gripping or releasing engagement, allowing the filter rod 400 to be limited or movably positioned between the clamping component 151 and the supporting component 110 in the height direction Z, thereby adjusting the cutting position of the filter rod 400 relative to the cutting component 121. In one example, the control component 140 is communicatively connected to the third drive component 152, and the control component 140 controls the third drive component 152 to drive according to control commands.

[0052] Thus, the clamping assembly 151 can fix the filter rod 400 on the bearing assembly 110, preventing the filter rod 400 from moving or vibrating during the cutting process. Specifically, after the filter rod 400 is placed on the bearing assembly 110, the clamping assembly 151, driven by the third drive assembly 152, moves along the direction close to the filter rod 400 (i.e., the height direction Z) and abuts against the filter rod 400, firmly pressing the filter rod 400 onto the bearing assembly 110. This helps to prevent the filter rod 400 from shifting when it is cut with the cutting assembly 121, improving the positioning stability of the filter rod 400 and thus improving the cross-sectional cutting effect of the filter rod 400.

[0053] Furthermore, the third drive assembly 152 drives the pressing assembly 151 to move along the height direction Z, thereby achieving the pressing and releasing of the filter rod 400 and realizing the intelligent positioning effect of the filter rod 400 in the filter rod section cutting device 100. The third drive assembly 152 can be a cylinder, hydraulic cylinder, electric push rod, or other type of drive device.

[0054] In some embodiments, see back Figure 5 The third drive assembly 152 includes a power source 1521 and a telescopic rod 1522. One end of the telescopic rod 1522 is driven by the power source 1521, and the other end is connected to the clamping assembly 151. The power source 1521 drives the telescopic rod 1522 to extend and retract along the height direction Z, causing the telescopic rod 1522 to switch the clamping assembly 151 between a first position and a second position, so that the clamping assembly 151 switches between being spaced apart from the filter rod 400 and being in contact with the filter rod 400.

[0055] Understandably, when the clamping assembly 151 is in the first position, it holds the filter rod 400 against the support assembly 110. When the clamping assembly 151 is in the second position, it releases its grip on the filter rod 400. This improves the positioning effect of the filter rod 400 through the clamping assembly 151.

[0056] In one example, the power source 1521 is communicatively connected to the control component 140. It is understood that the control component 140 only needs to control the third drive component 152 to extend and retract the telescopic rod 1522 between the first and second positions. That is, the driving stroke of the third drive component 152 on the telescopic rod 1522 can be a fixed value. This reduces the difficulty of controlling the third drive component 152 and lowers the requirements for the algorithm and computing power of the control component 140.

[0057] It should be noted that the power source 1521 in the above embodiments can be, but is not limited to, a cylinder assembly, or a hydraulic cylinder, etc., without further restrictions.

[0058] In some embodiments, the control commands described above can be implemented through the internal control logic of the control component 140. Specifically, see [link to previous section]. Figure 1 as well as Figure 2 The filter rod section cutting device 100 also includes a photoelectric sensing component 160. The photoelectric sensing component 160 is used to detect whether a filter rod 400 is present at the cutting position. The photoelectric sensing component 160 is communicatively connected to the control component 140. When the photoelectric sensing component 160 does not detect the filter rod 400, the control component 140 controls the second drive component 132 to drive the push rod component 131 to move, so that the push rod component 131 drives the filter rod 400 to move towards the cutting position.

[0059] Understandably, the detection principle of the photoelectric sensing component 160 is that it emits a light beam from its emitting part to form an optical axis channel. When an object is present in this optical axis channel, the light beam entering the receiving part of the photoelectric sensing component 160 is blocked (specifically, the amount of detected light is reduced, the light intensity is reduced, or the transmission speed is slowed down, etc.), thus indicating that an object has been detected. Conversely, when the object is not in the optical axis channel, the light beam entering the receiving part of the photoelectric sensing component 160 is not blocked, thus indicating that no object has been detected. In other words, whether the optical axis channel formed within the photoelectric sensing component 160 is blocked by the filter rod 400 can be used to determine whether the filter rod 400 is present at the cutting position.

[0060] Specifically, in one implementation scenario, when the photoelectric sensing component 160 detects that the filter rod 400 is at the cutting position, the filter rod 400 can be installed in place, and the driving of the second driving component 132 on the push rod component 131 can be stopped, so that the filter rod 400 can be relatively stationary on the support component 110. Correspondingly, when the photoelectric sensing component 160 detects that the filter rod 400 is not at the cutting position, the driving of the second driving component 132 on the push rod component 131 can continue until the photoelectric sensing component 160 detects that the filter rod 400 is at the cutting position.

[0061] Thus, the presence of the filter rod 400 at the cutting position can be determined by the photoelectric sensing component 160, so that the control component 140 can accurately drive the second driving component 132 to drive the push rod component 131. This improves the accuracy of the push rod component 131 in positioning the filter rod 400 in the length direction X, thereby improving the positioning effect of the filter rod 400 relative to the cutting component 121 in the length direction X, and consequently improving the cross-sectional cutting effect of the filter rod 400.

[0062] It should be noted that the number of photoelectric sensing components 160 can be one or more. In addition, the position of the photoelectric sensing component 160 can be opposite to the head of the filter rod 400, opposite to the tail of the filter rod 400, or even at any position on the filter rod 400.

[0063] Alternatively, in one embodiment, see back Figure 2 The photoelectric sensing component 160 includes a first photoelectric sensor 161 and a second photoelectric sensor 162. Both the first photoelectric sensor 161 and the second photoelectric sensor 162 are driveably connected to the control component 140. The filter rod 400 is provided with a first end and a second end opposite to each other. The first photoelectric sensor 161 is used to detect the presence of the first end, and the second photoelectric sensor 162 is used to detect the presence of the second end. The control component 140 is used to adjust the driving amount of the second drive component 132 on the push rod component 131 according to the presence of the first end and the second end.

[0064] For ease of understanding, the following description will illustrate the implementation process of the first photoelectric sensor 161 and the second photoelectric sensor 162 in an implementation scenario. It should be noted that the implementation process mentioned here is merely one step in the implementation and does not imply that this embodiment is limited to this specific method.

[0065] Assume that the first end is positioned close to the cutting component 121 and the second end is positioned far away from the cutting component 121.

[0066] When the first photoelectric sensor 161 does not detect the presence of the first end, and the second photoelectric sensor 162 detects the presence of the second end, it can be determined that the filter rod 400 and the cutting assembly 121 are not installed in place. It is necessary to continue driving the second driving assembly 132 to drive the push rod assembly 131 so that the push rod assembly 131 can lift the filter rod 400 and move it in the direction close to the cutting assembly 121.

[0067] When the first photoelectric sensor 161 detects the presence of the first end and the second photoelectric sensor 162 detects the presence of the second end, it can be determined that the head of the filter rod 400 has reached the relative setting position with the cutting component 121. However, since the cutting component 121 needs to cut the non-head and non-tail positions of the filter rod 400, in this scenario, the position of the preset cutting section in the filter rod 400 is still not accurately aligned with the cutting component 121. At this time, the second driving component 132 can continue to drive the push rod component 131, so that the push rod component 131 can lift the filter rod 400 and move it in the direction close to the cutting component 121.

[0068] When the first photoelectric sensor 161 detects the presence of the first end and the second photoelectric sensor 162 detects the absence of the second end, it can be determined that the position of the preset cutting section in the filter rod 400 is accurately aligned with the cutting component 121. At this time, the driving of the second driving component 132 can be stopped, so that the push rod component 131 no longer lifts and engages with the cutting component 121.

[0069] In this way, the detection cooperation between the first photoelectric sensor 161 and the first end, as well as the detection cooperation between the second photoelectric sensor 162, can help improve the positioning accuracy of the filter rod 400, thereby improving the accuracy of the cutting assembly 121 in cutting the cross section of the filter rod 400.

[0070] In one example, the first end can be the head of the filter rod 400, and the second end can be the tail of the filter rod 400.

[0071] In conjunction with any embodiment of the above-described carrier component 110, in conjunction with Figure 5 as well as Figure 6 As shown, the supporting component 110 is provided with a plurality of limiting grooves 110a, which engage with the filter rod 400 for limiting. Thus, the design of the limiting grooves 110a limits the filter rod 400 in the height direction Z, enhancing the positioning stability of the filter rod 400 on the supporting component 110. Correspondingly, the design of the limiting grooves 110a is relatively simple and easy to install, which is beneficial for improving the processing efficiency of the filter rod cross-section cutting device 100 and reducing processing costs.

[0072] Furthermore, in some embodiments, such as Figure 6 As shown, the supporting assembly 110 includes a limiting member 111 and a guiding member 112. The limiting member 111 and the guiding member 112 are adjacent to each other and connected in the radial direction Y (i.e., the direction perpendicular to the length direction X), and the guiding member 112 is located on the side of the limiting member 111 away from the cutting assembly 121. The sidewalls of the limiting member 111 and the sidewalls of the guiding member 112 are connected and cooperate to form a limiting groove 110a. The guiding member 112 is inclined and is used to guide the filter rod 400 to slide into the limiting groove 110a.

[0073] Understandably, the guide member 112 is inclined away from the ground, allowing it to limit the filter rod 400 on one side in the radial direction Y, preventing the filter rod 400 from shifting or slipping on one side and improving its positioning stability. Furthermore, the limiting member 111 and the guide member 112 are connected to form a limiting groove 110a, eliminating the need for additional machining to create the limiting groove 110a, reducing machining steps and improving processing efficiency.

[0074] Optionally, in one embodiment, the limiting member 111 is also inclined in a direction away from the ground, and the limiting member 111 and the guide member 112 are inclined in a direction away from each other. In this way, the limiting member 111 can also limit the filter rod 400 on the other side in the radial direction Y. In cooperation with the guide member 112, it can form a bidirectional limiting of the filter rod 400 in the radial direction Y, which improves the positioning stability of the filter rod 400.

[0075] In some embodiments, see back Figure 5 as well as Figure 6 The filter rod section cutting device 100 also includes a feeding module 170. The feeding module 170 includes a feeding assembly 171. The feeding assembly 171 includes a mounting housing 1711 and a roller body 1712. The mounting housing 1711 is provided with a feed inlet 1711a, a mounting cavity 1711b, and a discharge outlet 1711c at intervals. The edge of the discharge outlet 1711c is connected to the support assembly 110 so that the filter rod 400 can move to the support assembly 110 through the discharge outlet 1711c. The mounting cavity 1711b is used to mount the roller body 1712, and the roller body 1712 is rotatably mounted on the mounting housing 1711.

[0076] When the roller body 1712 is installed in the mounting cavity 1711b, the roller body 1712 is spaced apart from the feed inlet 1711a to form a first gap channel 171a, and the roller body 1712 is spaced apart from the discharge outlet 1711c to form a second gap channel 171b. The gap width of both the first gap channel 171a and the gap width of the second gap channel 171b are greater than the diameter of the filter rod 400. However, the gap width of at least one of the first gap channel 171a and the second gap channel 171b is less than the sum of the diameters of the two filter rods 400.

[0077] Understandably, the filter rod 400 enters the mounting cavity 1711b through the feed port 1711a. Specifically, when the drum body 1712 rotates, it can guide the filter rod 400 through the first gap channel 171a into the mounting cavity 1711b, and discharge it from the discharge port 1711c through the second gap channel 171b. The filter rod 400 moves to the bearing assembly 110 through the discharge port 1711c and enters the cutting area.

[0078] Based on this, the rotation of the roller body 1712 drives the feeding of the filter rods 400, which helps to improve the uniformity of the feed of the filter rods 400. Furthermore, the gap width is greater than the diameter of the filter rods 400, ensuring that the filter rods 400 can smoothly enter the mounting cavity 1711b and also guaranteeing the normal output of the filter rods 400 at the discharge port 1711c. At least one of the gap widths is less than the sum of the diameters of the two filter rods 400, ensuring that only one filter rod 400 can exit through the discharge port 1711c during the feeding process. This helps prevent more than one filter rod 400 from simultaneously exiting through the discharge port 1711c during the feeding process, which could lead to excessive cutting sections during the final cutting, affecting quality inspection and thus improving the quality of the filter rod 400 section inspection.

[0079] Optionally, in one embodiment, the edge of the discharge port 1711c can be connected and engaged with the side of the guide member 112 away from the limiting member 111 in the above embodiment. This allows the filter rod 400 exiting the discharge port 1711c to slide onto the guide member 112 under the influence of gravity due to the inclined design of the guide member 112, and then proceed to the limiting groove 110a via the guide member 112, thereby achieving the installation and limiting of the filter rod 400 on the supporting component 110. In this way, it can be ensured that each filter rod 400 can fall into the limiting groove 110a and be installed and limited in engagement with the supporting component 110, improving the stability of the filter rod cross-section cutting device 100.

[0080] It should be noted that the rolling of the roller body 1712 can be controlled manually or electrically.

[0081] Furthermore, in other embodiments, see back Figure 2 , Figure 5 as well as Figure 6 The feed module 170 of the filter rod section cutting device 100 also includes a fourth drive assembly 172. The fourth drive assembly 172 is used to drive the drum body 1712 to rotate. In one example, the fourth drive assembly 172 can be communicatively connected to a control assembly 140, and the control assembly 140 is used to drive the fourth drive assembly 172 to rotate the drum body 1712 according to control commands. This improves the intelligence level of the filter rod section cutting device 100.

[0082] In conjunction with any of the embodiments of the first drive component 122, the second drive component 132, and the fourth drive component 172 described above, see back Figure 1The first drive assembly 122 and the second drive assembly 132 can be adjustable-stroke drive assemblies, such as a transmission assembly between a motor and a flexible belt, a transmission assembly between a linear motor and a slider, or a transmission assembly between a motor and an electric actuator. The fourth drive assembly 172 can be, but is not limited to, a transmission assembly between a motor and a rotating bearing, or a transmission assembly between a motor and a gear component.

[0083] In one embodiment, such as Figure 7 As shown, the first drive assembly 122 includes a first motor 1221 and a lead screw 1222. The lead screw 1222 extends in the radial direction Y. The cutting assembly 121 has a through hole with an internal thread structure on the inner wall of the through hole, and the lead screw 1222 has an external thread structure. The lead screw 1222 is inserted into the through hole, and the internal and external thread structures are screwed together. When the motor drives the lead screw 1222 to rotate, the lead screw 1222 can convert the rotational motion into linear motion of the cutting assembly 121, thereby realizing the movement of the cutting assembly 121 in the radial direction Y.

[0084] In another embodiment, see back Figure 1 The second drive assembly 132 includes a second motor, a ball screw, and a slider. The second motor drives the ball screw, and the slider is rigidly connected to the push rod assembly 131, with the ball screw extending along the length direction X. When the second motor rotates, it drives the ball screw to rotate synchronously. The ball screw converts the rotational motion into linear motion of the slider, thereby enabling the slider to move in the radial direction Y. This allows the slider to drive the push rod assembly 131 to move towards or away from the filter rod 400.

[0085] In other embodiments, such as Figure 6 As shown, the fourth drive assembly 172 includes a third motor 1721, a rotating shaft 1722, and a transmission belt 1723. The rotating shaft 1722 is connected to the drum body 1712 to drive the drum body 1712 to rotate synchronously. The transmission belt 1723 is wound between the third motor 1721 and the rotating shaft 1722. When the third motor 1721 is driven, the rotating shaft 1722 can be driven to rotate synchronously through the transmission belt 1723, thereby realizing the rotation of the drum body 1712. The rotation direction of the drum body 1712 can be changed by changing the rotation direction of the third motor 1721.

[0086] In some embodiments, see back Figure 4 The filter rod cross-section detection system 10 also includes a waste collection component 500, which is located below the support assembly 110 and opposite to the head of the filter rod 400. The waste collection component 500 is used to collect the waste material after the filter rod 400 has been cut, reducing the tediousness of subsequent cleaning.

[0090] 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.
