Description

Technical Field

[0001] The present invention relates to the technical field of tobacco machinery, and particularly relates to a guide rail for a drum and a tobacco processing device. Background Art

[0002] In tobacco machinery, some tobacco processing devices use drums to convey base rods. Multiple drums are arranged in sequence to continuously convey the base rods. During the conveying process, the base rods are usually processed, such as slitting, offsetting, tipping, etc. A guide rail is arranged between some adjacent drums. The guide rail extends into the junction of the two drums, so as to guide the base rod through the guide rail and guide the base rod from the wheel groove of the upstream drum to the wheel groove of the downstream drum to achieve stable transfer of the base rod.

[0003] However, during the production of tobacco processing devices in the current technology, when the base rod enters the downstream drum from the upstream drum through the guide rail, problems such as unstable transfer of the base rod and rod leakage are likely to occur. Especially when producing the base rod for heated cigarettes, such problems are particularly obvious. Summary of the Invention

[0004] Aiming at the technical problems that when the base rod in the prior art enters the downstream drum from the upstream drum through the guide rail, the transfer of the base rod is unstable and rod leakage is likely to occur. The applicant believes that such problems are mainly caused by factors such as the physical properties of the base rod itself and processing errors. For example, in the field of heated cigarettes, there are many types of specifications of the base rod materials for heated cigarettes, and the physical properties of the base rods of each specification type are inconsistent, and the physical properties vary greatly. Especially for the base rod materials with large differences in properties such as elasticity and hardness, there are great differences in the processing quality of the upstream equipment. After being processed by the upstream processing equipment, the roundness and filling uniformity of the base rod are poor, so that the base rod is likely to have problems such as unstable transfer and rod leakage when flowing through the guide rail. The present invention provides a guide rail for a drum, in which the guide rail and the base are connected and limited by an elastic member. After the guide rail is stressed, it can retract to a certain extent, so that the base rod can flow through the guide rail more smoothly, so that the base rod can be transferred more stably and the problem of rod leakage can be better avoided.

[0028] The present invention provides a guide rail for a drum wheel, which includes a base, a guide rail and an elastic member; a guide portion for guiding a base rod is provided on the guide rail, the guide rail is installed on the base, and the guide rail has an automatic degree of movement in a direction away from the guide portion on the base; the elastic member is provided on the base, and the elastic member abuts against the guide rail to limit the movement of the guide rail in a direction away from the guide portion. The guide rail in the guide rail for the drum wheel is not completely fixed on the base, but has a certain degree of freedom, so that when some non-standard base rods (such as base rods with excessive diameter, base rods with abnormal roundness, base rods with excessive hardness, etc.) flow through the guide rail, the guide rail can be squeezed back, and the guide rail can avoid such base rods. At the same time, the elastic member is also provided to abut against the guide rail, so as to provide a certain pre-tightening force to the guide rail, so that the guide rail can smoothly guide the base rod to transfer to the downstream drum wheel.

[0029] Please refer to Figures 1 to 3 In one embodiment, a drum guide rail 100 is provided, which is mainly used to solve the problems of unstable base rod handover and rod leakage in the prior art when the guide rail is used.

[0030] The drum guide rail 100 includes a base 10, a guide rail 20 and an elastic member 30. The guide rail 20 is provided with a guide portion 21 for guiding the base rod. The guide rail 20 is installed on the base 10, and the guide rail 20 has the freedom to move in a direction away from the guide portion 21 on the base 10. In other words, the guide rail 20 is not completely fixed on the base 10, but has the freedom to move in a partial direction, and this direction is in the direction away from the guide portion 21, so that the guide rail 20 is buffered at a certain retracted position. When individual non-standard base rods flow through the guide portion 21, the non-standard base rods will generate pressure on the guide portion 21, thereby prompting the guide rail 20 to retreat, so that the non-standard base rods can flow smoothly through the guide rail 20.

[0031] The elastic member 30 is disposed on the base 10, and the elastic member 30 abuts against the guide rail 20 to limit the movement of the guide rail 20 in the direction away from the guide portion 21. The elastic member 30 refers to a component that can undergo elastic deformation after being subjected to a force, and can automatically restore its initial shape after the force is reduced or disappears. In other words, although the guide rail 20 has the freedom to move in the direction away from the guide portion 21, the guide rail 20 is still limited by the elastic member 30 on the base 10. The elastic member 30 can apply a certain pre-tightening force to the guide rail 20, thereby ensuring that the guide rail 20 can be stabilized in the desired installation position and ensuring the normal guidance of the normal base rod. When some non-standard base rods (such as base rods with excessive diameter, base rods with abnormal roundness, base rods with too high hardness, etc.) flow through the guide rail 20, the force applied by such base rods to the guide rail 20 will be greater than the pre-tightening force applied by the elastic member 30 to the guide rail 20, thereby pushing the guide rail 20 to move slightly and causing the elastic member 30 to deform. After such base rods flow through, the guide rail 20 will return to its initial position driven by the elastic member 30 and continue to guide subsequent normal base rods.

[0032] It is understandable that in the prior art tobacco processing equipment, when the base rod flows through the guide rail during production, the base rod handover is prone to be unstable, resulting in rod leakage or even rod jamming. This problem is particularly evident when producing base rods for new tobacco (heated cigarettes).

[0033] The applicant believes that the occurrence of such problems is mainly due to the physical properties of the base rod itself and processing errors. Since the physical properties of base rods of various specifications are different, there will be an obvious gap in the yield rate of different base rods after being processed by upstream equipment. For example, base rod materials with large differences in properties such as elasticity and hardness have great differences in the processing quality of upstream equipment. After being processed by upstream processing equipment, the roundness and filling uniformity of the base rods are poor. In the prior art, the guide rail is completely fixed in position, and the distance between the guide rail and the drum is set according to the diameter of the standard base rod. Once the diameter of the base rod processed from upstream is not the standard diameter, it is not easy to flow through between the guide rail and the drum. The applicant believes that this is the key reason why the base rod is prone to handover problems at the guide rail in the current technology.

[0034] Heated tobacco products are a new type of tobacco that has emerged in recent years. There are many types of base rods for heated tobacco products, and the physical properties of various types of base rods vary greatly. Therefore, after being processed by upstream equipment, problems with the yield rate are likely to occur. The applicant also believes that since heated tobacco products have emerged in recent years, the equipment and processes for processing heated tobacco products are less mature and stable compared to traditional cigarettes. Therefore, problems with the yield rate are likely to occur in the base rods of heated tobacco products. This also poses certain requirements for the guide rails, drums, etc. that come into contact with the base rods. The guide rail structure of traditional cigarettes can no longer meet the requirements for the uniform supply of base rods for new tobacco products.

[0035] For the guide rail 100 for the drum provided in this embodiment, the guide rail 20 used has a degree of freedom to move within a certain range, and the position of the guide rail 20 is automatically adjustable. When a hard base rod or an individual base rod (a base rod with a diameter larger than the predetermined diameter) passes through the guide rail, such a base rod can squeeze the guide rail 20, and the force applied to the guide rail 20 is greater than the pre-tightening force applied by the elastic member 30, thereby causing the elastic member 30 to deform, allowing the guide rail 20 to move slightly, so that non-standard base rods can flow smoothly through the guide rail 20, enabling the base rods to be handed over more stably and better avoiding problems such as missing rods and stuck rods. Since the elastic member 30 can provide a certain pre-tightening force to the guide rail 20, it can prompt the guide rail 20 to maintain its position state, thereby smoothly guiding each base rod into the downstream drum and improving the stability of the equipment operation.

[0036] Preferably, in one embodiment, the drum guide rail 100 further includes a connecting member 40. The guide rail 20 is mounted on the base 10 through the connecting member 40. The connecting member 40 is movably connected to the guide rail 20 and abuts against the base 10. The connecting member 40 is mainly used to firmly fix the guide rail 20 on the base 10 without affecting the freedom of normal retraction of the guide rail 20, thereby ensuring the stable and reliable position of the guide rail 20 and guaranteeing the guiding effect of the guide rail 20 on each base rod. At the same time, by moving the connecting member 40, on-line fine adjustment of the guide rail 20 can be achieved.

[0037] Preferably, in one embodiment, the guide rail 20 includes a guide rail body 22 and a mounting block 23. The guiding portion 21 is located at one end of the guide rail body 22, and the other end of the guide rail body 22 is fixed to the mounting block 23. The connecting member 40 is connected to the mounting block 23, and the elastic member 30 abuts against the mounting block 23. By connecting to the connecting member 40 through the mounting block 23, the connection stability can be improved, and the mounting block 23 can also make the elastic member 30 abut against the guide rail 20 more stably and apply a pre-tightening force to the guide rail 20 more stably.

[0038] Specifically, in one embodiment, the guide rail body 22 is fastened to the mounting block 23 by screws. More specifically, the guide rail body 22 is pressed by screws in the groove of the mounting block 23, and the groove of the mounting block 23 is slightly larger than the thickness of the guide rail body 22.

[0039] Preferably, in one embodiment, the base 10 includes a bottom plate 11 and side plates 12 disposed on the bottom plate 11. The side plates 12 include a front surface 122 and a back surface 123 opposite to the front surface 122. The front surface 122 is located on the side close to the mounting block 23, and the back surface 123 is located on the side away from the mounting block 23. Mounting holes 121 are formed in the side plates 12. The connecting member 40 abuts against the back surface 123, and after passing through the mounting holes 121, the connecting member 40 is connected to the mounting block 23. The mounting block 23 is spaced apart from the front surface 122, that is, there is a gap between the mounting block 23 and the front surface 122. The elastic member 30 is disposed on the side plate 12 and abuts against the mounting block 23 after protruding from the front surface 122 of the side plate 12. That is to say, in this embodiment, both the connecting member 40 and the elastic member 30 are connected to the side plate 12. The connecting member 40 abuts against the back surface 123 of the side plate 12 to limit the position of the mounting block 23, and the elastic member 30 abuts against the mounting block 23 after protruding from the front surface 122 to limit the position of the mounting block 23. And because there is a gap between the mounting block 23 and the front surface 122, when an individual non-standard base rod presses the guide rail body 22, the mounting block 23 can be urged to move towards the front surface 122, so that the guide rail body 22 can avoid the non-standard base rod. As Figure 2 In the illustrated embodiment, after the connecting member 40 abuts against the back surface 123, it is mainly used to limit the movement of the mounting block 23 towards the right side. After the elastic member 30 abuts against the mounting block 23, it is mainly used to limit the movement of the mounting block 23 towards the left side.

[0040] Specifically, in one embodiment, the mounting block 23 is located on the bottom plate 11. The bottom plate 11 can support and hold the mounting block 23, enabling the mounting block 23 to be stably stressed and preventing the mounting block 23 from tilting.

[0041] Preferably, in one embodiment, the mounting holes 121 are waist-shaped holes, and the mounting holes 121 extend in the height direction. By setting the mounting holes 121 as waist-shaped holes, the adjustment of the up-and-down position can be achieved. Additionally, it can be understood that when the guide rail 20 is in use and the base rod flows through the guide rail body 22, the force exerted on the guide rail body 22 by the base rod is not necessarily a horizontal force. When the base rod presses the guide rail body 22, it may cause the guide rail body 22 to tilt upward. By setting the mounting holes 121 as waist-shaped holes, after the guide rail 20 is subjected to the pressure of the base rod, there will be no resistance to the upward tilt of the guide rail 20 between the connecting member 40 and the hole wall of the mounting hole 21, enabling the guide rail 20 to retract smoothly and allowing the base rod to flow through the guide rail 20 smoothly.

[0042] More preferably, in one embodiment, the connecting member 40 is located below the elastic member 30, which is beneficial for the guide rail 20 to retreat under force.

[0043] Specifically, in one embodiment, the connecting member 40 is a screw, a threaded hole matching the connecting member 40 is formed in the mounting block 23, the head 41 of the connecting member 40 abuts against the back surface 123, and the rod portion 42 of the connecting member 40 passes through the mounting hole 121 and is threadedly connected to the mounting block 23. With this structure, the connection stability can be improved. Additionally, by screwing the connecting member 40, the position of the mounting block 23 on the base 10 can also be adjusted, facilitating the on-line fine adjustment of the position of the guide rail body 22, enabling the drum guide rail 100 to quickly adapt to the production and use of base rods of various specifications and types.

[0044] Specifically, in one embodiment, a gasket 43 is provided between the head 41 of the connecting member 40 and the back surface 123.

[0045] Preferably, in one embodiment, the elastic member 30 is adjustably arranged on the base 10. Herein, the elastic member 30 being adjustably arranged on the base 10 means that the pre-tightening force exerted by the elastic member 30 on the guide rail 20 is adjustable. The specific form can be: the elastic member 30 is movably arranged on the base 10, and by adjusting the position of the elastic member 30 on the base 10, the adjustment of the pre-tightening force is achieved; or it can also be that the elastic member 30 itself can achieve the adjustment of the outward elastic force applied, thereby achieving the adjustment of the pre-tightening force. Specifically, in one embodiment, the elastic member 30 is a spring plunger, and the elastic member 30 is threadedly connected to the base 10, so that the pre-tightening force can be adjusted by screwing the elastic member 30. With this structure, the pre-tightening force exerted by the elastic member 30 can be quickly adjusted.

[0046] Preferably, in one embodiment, the guide rail 100 for the drum further includes a mounting bracket 50 and a base locking member 60. The base 10 is slidably disposed on the mounting bracket 50. The base locking member 60 is movably disposed on the base 10 and abuts against the mounting bracket 50 to limit the sliding of the base 10. By slidably disposing the base 10 on the mounting bracket 50, the position of the base 10 can be quickly adjusted, so as to quickly adjust the position of the guide rail 20, enabling the guide rail 100 for the drum to be quickly adapted for use with different drums and base rods of different length specifications. Specifically, after the guide rail 100 for the drum is installed, the length direction of the mounting bracket 50 is parallel to the axial direction of the drum, and the slidable direction of the base 10 is along the length direction of the mounting bracket 50. By sliding the base 10 relative to the mounting bracket 50, the relative position of the guide rail 20 and the drum in the axial direction can be adjusted, so as to better adapt for use with different drums and base rods of different length specifications. The base locking member 60 is mainly used to fasten the base 10 to the mounting bracket 50. After the position of the base 10 is adjusted, the base 10 is locked by the base locking member 60, thereby fixing the position of the base 10 on the mounting bracket 50. When the position of the base 10 needs to be adjusted, only the base locking member 60 needs to be moved to loosen the base 10. With this structure, the position of the guide rail 20 can be quickly adjusted, enabling the guide rail 100 for the drum to be better adapted for use with different drums, improving the versatility. In addition, with this structure, the installation and disassembly of components are also facilitated. By loosening the base locking member 60, the base 10 and the guide rail 20 as a whole can be detached from the mounting bracket 50, facilitating the disassembly and assembly of components.

[0047] Specifically, in one embodiment, the base locking member 60 is a locking screw. The base locking member 60 is threadedly connected to the base 10, and the end face of the base locking member 60 abuts against the side surface of the mounting bracket 50.

[0048] Specifically, in one embodiment, when the mounting bracket 50 is installed, it is fixed to the wall panel of the unit equipment by screws and step pins. More specifically, the mounting bracket 50 is fixed to the wall panel by two screws and two step pins.

[0049] Preferably, in one embodiment, a positioning pin 13 is provided on the base 10, and a positioning groove 51 matching the positioning pin 13 is provided on the mounting bracket 50, and the positioning groove 51 extends along the slidable direction of the base 10. Through the positioning cooperation between the positioning pin 13 and the positioning groove 51, the installation efficiency of the base 10 can be improved. After the base 10 and the guide rail 20 are integrally detached from the mounting bracket 50, due to the positioning of the pin holes, it can operate without readjustment after disassembly and reassembly. And the positioning groove 51 extends along the slidable direction of the base 10. When it is necessary to slide and adjust the position of the base 10, the positioning pin 13 can also move along the positioning groove 51, without affecting the sliding adjustment of the base 10 on the mounting bracket 50.

[0050] More preferably, in one embodiment, an avoidance hole 231 is provided at the bottom of the mounting block 23 corresponding to the positioning pin 13, and the dimension of the avoidance hole 231 in the width direction is larger than that of the positioning pin 13, so that the positioning pin 13 does not affect the force return of the guide rail body 22.

[0051] Preferably, in one embodiment, an adjusting member 52 is further provided on the mounting bracket 50, and the adjusting member 52 is used to adjust the height of the base 10 relative to the mounting bracket 50. The base 10 can be adjusted up and down through the adjusting member 52, so as to change the position of the base 10, thereby realizing the online adjustment of the up and down position of the guide rail 20.

[0052] Specifically, in one embodiment, the adjusting member 52 is a screw, the adjusting member 52 is threadedly connected to the mounting bracket 50, and the adjusting member 52 is located at the bottom of the base 10. When it is necessary to adjust the height of the mounting bracket 50, it can be adjusted correspondingly by turning the adjusting member 52, which is convenient and fast.

[0053] Preferably, in one embodiment, a wheel groove cleaning and blowing mechanism 70 is provided on the top of the mounting bracket 50. The wheel groove cleaning and blowing mechanism 70 is mainly used to connect to an external air source device, so as to blow out air through the wheel groove cleaning and blowing mechanism 70 to blow and clean the wheel grooves of the upstream drum.

[0054] Preferably, in one embodiment, a detection mechanism 80 is provided at the bottom of the mounting bracket 50. The detection mechanism 80 is mainly used to detect the wheel grooves of the downstream drum and detect the absence of the base rods in the downstream drum.

[0055] Preferably, in one embodiment, a blowing cleaning mechanism 90 is further provided at the bottom of the mounting bracket 50, and the blowing port of the blowing cleaning mechanism 90 is directly facing the detection head of the detection mechanism 80. The blowing cleaning mechanism 90 mainly cleans the detection mechanism 80 to prevent dust particles and the like from interfering with the detection mechanism 80, thereby improving detection accuracy.

[0056] The drum wheel guide rail 100 has a certain gap self-adjustment capability. When the cross-section of the base rod is too large, the guide rail body 22 can be properly pushed open to allow it to pass smoothly. Then the guide rail body 22 can automatically reset to the initial adjustment position. The drum wheel guide rail 100 can adapt to a wider range of base rod shapes and has strong fault tolerance, which plays a key role in the stable operation of the equipment. When adjusting the specifications of base rods of different lengths, it is only necessary to adjust the position of the guide rail body 22 on the mounting bracket 50. There is no need to replace parts, and the specification replacement is more convenient, and adjustment, disassembly and maintenance are more convenient. The drum wheel guide rail 100 has the characteristics of good interchangeability, online fine-tuning, and automatic adjustment. It will not easily cause the machine to stop, and can adapt to the stable transportation of diverse base rods in the field of heated cigarettes. It is a good solution to the problems existing in the production of new tobacco and greatly improves the equipment operation efficiency.

[0057] At the same time, in one embodiment, a tobacco processing equipment 1000 is also provided, which includes a first drum wheel 200, a second drum wheel 300 adjacent to the first drum wheel 200, and a guide rail 100 for the drum wheel, the guide portion 21 extends into the intersection of the first drum wheel 200 and the second drum wheel 300, and the drum wheel guide rail 100 is used to guide the base rod from the first drum wheel 200 to the second drum wheel 300.

[0058] Preferably, in one embodiment, a guide device 500 is further provided on the opposite side of the drum guide rail 100. Specifically, the guide device 500 can be provided on the second drum 300.

[0059] Specifically, in one embodiment, the first drum wheel 200 is a cutting wheel, and the second drum wheel 300 is a dislocation wheel. The first drum wheel 200 receives the base rod from the hopper through negative pressure adsorption, and then the base rod is divided into 2 or more sections after passing through the cutting device 400 (the cutting device 400 can be configured with one or more cutters according to the required length requirements of the base rod). The cut base rod continues to be transported backward under the action of the first drum wheel 200, and under the action of the drum wheel guide rail 100, the base rod at the front end is first taken away by the drum wheel guide rail 100 and the second drum wheel 300, and the base rod at the rear end is then taken away, so as to achieve the dislocation of the base rod after cutting. The drum wheel guide rail 100 and the guide device 500 form a material flow channel to achieve the orderly flow of the base rod.

[0060] Specifically, the number of the guide rails 20 provided on the mounting bracket 50 can be selected according to the number of the base rods cut by the first drum 200.

[0061] Preferably, in an embodiment, one side surface of the guiding portion 21 close to the second drum 300 is an arc surface 211. Through the arrangement of the arc surface 211, the base rod can be properly protected after being transferred to the second drum 300, so as to avoid the fluctuation when the base rod does not fall into the groove after the transfer.

[0062] The base rod cut by the cutting device 400 is between the wheel groove of the first drum 200 and the arc of the guiding device 500. As the first drum 200 rotates, under the action of the guiding portion 21, the base rod slides out of the wheel groove of the first drum 200 and falls between the guiding portion 21 and the guiding device 500. As the second drum 300 rotates, the base rod is driven to fall forward into the wheel groove of the second drum 300, and then is stably conveyed between the arc surface 211 of the guiding portion 21 and the wheel groove of the second drum 300. When a too hard base rod or an individual base rod has a cross-section larger than a predetermined diameter between the guiding portion 21 and the guiding device 500, when the force applied by the base rod to the guiding portion 21 is greater than the pre-tightening force, the elastic member 30 can be pushed to realize the micro-movement of the guiding portion 21, and then it immediately returns to its original position.

[0063] It can be understood that new tobacco (heated tobacco products) has become popular abroad in recent years, and there is no special equipment for the production of heated tobacco products in China yet. In order to adapt to the new situation and meet the future large-scale production needs of domestic major tobacco companies for heated tobacco products, the applicant has developed a production equipment for heated tobacco products. Since heated tobacco products have different process routes and different equipment configurations are required for different processes, in order to quickly configure and assemble complete sets of equipment, the applicant has designed a set of production equipment for heated tobacco products, which adopts the modular design guiding principle, facilitating production enterprises to conveniently and quickly assemble different equipment configurations to meet the different processes of new tobacco products. The interchangeability of the guide rails 100 for the drums is good, with characteristics such as on-line fine adjustment and automatic adjustment, which can adapt to the stable cutting misalignment of various base rods in the field of heated tobacco products and can well adapt to production equipment with different processes.

[0064] During installation, the distance between the guide rail 20 and the guiding device 500 can be adjusted according to requirements, and the clearance between the arc surface 211 of the guide rail 20 and the groove of the second drum 300 can be adjusted. The position of the base 10 can be adjusted according to the length so that the guide rail 20 can penetrate into the gap of the first drum 200 without interference. After the adjustment is in place, the entire guide rail 20 can be pulled out from the side by loosening the base locking member 60, and then can be installed as a whole without adjustment, which is convenient for disassembly and maintenance. During the operation of the equipment, the clearance between the guide rail 20 and the guiding device 500 can be fine-tuned online by adjusting the connecting member 40 according to the actual operation situation of the equipment, which is convenient and fast.

[0065] Preferably, in one embodiment, the air outlet of the groove cleaning and blowing mechanism 70 on the drum guide rail 100 faces the groove of the first drum 200. It can be understood that since the base rod on the cutting wheel groove will be cut, fine particles (especially in the case of heated cigarettes, fine particles are easily left) and other impurities will be left after cutting. The use of the groove cleaning and blowing mechanism 70 to clean the groove avoids the deposition of particulate matter and other impurities, and avoids the uneven adsorption and cutting of the base rod in the groove due to the deposition of impurities on the cutting wheel groove, thereby causing defective cigarettes. On the other hand, the deposition of impurities is also likely to cause the machine to stop.

[0066] Specifically, in one embodiment, the groove cleaning and blowing mechanism 70 includes a mounting plate 71, a first air pipe 72 and an elbow pipe 73. The mounting plate 71 is fixed on the mounting bracket 50, and an air duct is provided inside the mounting plate 71. The first air pipe 73 is connected to the mounting plate 71 through a first pipe joint 74, and the first air pipe 73 is communicated with the air duct. The elbow pipe 73 is connected to the mounting plate 71 through a second pipe joint 75. The elbow pipe 73 is communicated with the air duct, and the air outlet of the elbow pipe 73 faces the groove of the first drum 200. The first air pipe 72 is used to connect to an external air source, so as to blow out air flow through the elbow pipe 73 to clean the groove of the first drum 200. Preferably, in one embodiment, the elbow pipe 73 is located on the side away from the wall panel, so that air can be blown from the outside to the inside, and the impurities in the first drum 200 can be blown towards the wall panel, avoiding the blown impurities from affecting other components and facilitating the cleaning of the impurities.

[0067] More preferably, in one embodiment, the groove of the first drum wheel 200 has a negative pressure at the corresponding knife gap, so as to clean the knife gap. Specifically, the groove of the first drum wheel 200 has a negative pressure hole or a negative pressure groove at the position corresponding to the knife gap, and a negative pressure device is connected externally to form a negative pressure at the knife gap, so as to adsorb impurities such as particles and tows, so as to clean the knife gap. It can be understood that when the cutter cuts the base rod, it is easy to produce impurities such as particles, which are easy to affect the cutting quality and also easy to cause the wear of the cutter. In particular, some base rods in heated cigarettes are made of PLA material, and the impurities such as particles and tows generated after cutting are particularly obvious, which will greatly affect the stability of the equipment operation. In this embodiment, the groove of the first drum wheel 200 has a negative pressure at the corresponding knife gap, so that the particles generated after cutting can be cleaned, thereby ensuring the cutting quality of the subsequent base rods and improving the service life of the cutter.

[0068] Preferably, in one embodiment, the detection head of the detection mechanism 80 on the drum guide rail 100 faces the wheel groove of the second drum 300. The detection mechanism 80 is used to detect the missing of the base rods on the second drum 300. If too many base rods are missing continuously, it is necessary to check and eliminate the fault. It may be caused by unreasonable adjustment of the size of the guide rail 20 or changes in the base rods.

[0069] Specifically, the detection mechanism 80 may be a non-contact irradiation type detection mechanism such as a photoelectric sensor.

[0070] Specifically, in one embodiment, a fixing block 81 is provided at the bottom of the mounting bracket 50, and the detection mechanism 80 is provided on the fixing block 81. More specifically, in one embodiment, the fixing block 81 is fixed to the mounting bracket 50 by fixing screws 82 and pins 83, and the detection mechanism 80 is fixed to the fixing block 81 by screws. The blowing cleaning mechanism 90 includes a second air pipe 91, and the second air pipe 91 is installed on the fixing block 81 through a third pipe joint 92. An air hole or an air groove may be provided on the fixing block 81 at a position corresponding to the detection mechanism 80, so that the air flow is sent in through the second air pipe 91 and then blown out from the air hole or air groove on the fixing block 81, so as to clean the detection probe and light source of the detection mechanism 80.

[0071] The above description is only an implementation mode of the present invention. It should be pointed out that, for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present invention, but these all belong to the protection scope of the present invention.
