Description

Technical Field

[0001] This invention relates to the field of fragrance manufacturing equipment technology, specifically to a fragrance rinsing machine and its rinsing roller. Background Technology

[0002] Incense-sprinkling machines are used to produce incense sticks, which are long, thin, straight sticks, unlike coiled mosquito coils or block-shaped incense products. In the incense-sprinkling process, the incense sticks are placed inside a drum. The drum rotates, causing the incense sticks to tumble inside, while fragrance powder is sprinkled into the drum. The fragrance powder is evenly covered on the surface of the incense sticks during the tumbling process, resulting in the finished incense sticks.

[0003] In the fragrance application process, spice powder enters the drum through perforations in the drum wall and covers the surface of the tumbling incense sticks. The amount of spice powder supplied must match the size of the incense sticks. Too much powder results in wasted spice and excessive coverage, while too little powder leads to incomplete coverage, both affecting the quality of the finished incense sticks. Therefore, the opening size of the spice supply channel must be adjustable according to the incense stick specifications. Furthermore, after processing, the long, straight incense sticks must be removed from the drum, avoiding bending or damage during this process. Thus, the fragrance application machine drum must not only have the ability to continuously adjust the spice supply but also allow for convenient and damage-free removal of the incense sticks after processing.

[0004] Existing incense-dyeing machines typically have through holes in the inner cylinder. The relative movement of the inner cylinder and the drum causes the through holes to align with the perforations in the drum wall, forming a channel for the incense to pass through. However, once the channel opening size is set, it remains fixed. If the incense supply needs to be adjusted, the machine must be stopped, the inner cylinder removed from the drum, its installation position readjusted, and then it reinstalled. This adjustment process is cumbersome and cannot quickly switch the supply according to changes in the incense stick specifications during continuous processing. Furthermore, when removing the incense sticks after processing, the existing solution requires the operator to open the end of the drum or reach into the inner cylinder to manually retrieve the incense sticks. The long, straight incense sticks are prone to bending and damage during retrieval, making the incense removal operation inconvenient. Moreover, adjusting the incense supply and removing the incense sticks are two independent operations that require stopping the machine and performing them separately. This involves many steps, and the connection between adjustment and incense removal is not smooth, affecting the overall efficiency of incense-dyeing processing.

[0005] In summary, existing fragrance rinsing machine rollers have several drawbacks in terms of adjusting the fragrance supply and removing incense sticks. These include the need to stop the machine for disassembly and reassembly for opening adjustment, which is cumbersome; the need to manually retrieve incense sticks by reaching into the inner cylinder, which can easily damage the incense sticks; and the fact that adjustment and incense retrieval are independent of each other, with many operation steps and poor coordination. There is an urgent need in this field for a fragrance rinsing machine roller that can conveniently achieve continuous adjustment of the opening size of the fragrance supply channel and the lifting and removal of incense sticks without stopping the machine for disassembly and reassembly, with fewer operation steps and smooth coordination between adjustment and incense retrieval. Summary of the Invention

[0006] The purpose of this invention is to provide an incense applicator and its applicator roller to solve the above-mentioned problems. By moving the inner cylinder axially, the adjustment hole can be misaligned with the leakage hole. The overlapping area changes continuously with the amount of movement, and the size of the incense leakage hole opening is continuously adjusted accordingly. The amount of incense that can be passed through can be set according to the specifications of the incense sticks. At the same time, when the inner cylinder moves, the connecting rod drives the swing frame to swing, and the pad plate is lifted accordingly. When the incense stick is taken out, it is not necessary to insert it into the inner cylinder to lift the incense stick. When the inner cylinder moves in the opposite direction, the pad plate automatically falls back. One axial movement completes the opening adjustment and incense stick lifting at the same time. The operation steps are few, and the adjustment and incense taking are smoothly connected. See the following description for details.

[0007] To achieve the above objectives, the present invention provides the following technical solution: The present invention provides a fragrance spraying machine roller, including a roller and an inner cylinder. The roller is sleeved on the outside of the inner cylinder. Both the roller and the inner cylinder are hollow polygons. Each side wall of the inner cylinder is rotatably provided with a swing frame that penetrates the inner cylinder. The drum wall has multiple leakage holes, and the inner drum wall has multiple adjustment holes corresponding to the leakage holes. The overlapping position of the leakage hole and the corresponding adjustment hole is the fragrance leakage hole for the fragrance to pass through. The opening size of the fragrance leakage hole changes with the movement of the inner drum. A pad is fixed to the end of the swing frame located inside the inner cylinder, and a connecting rod is fixed to the other end of the swing frame. A support rod is rotatably provided at the end of the connecting rod. Multiple mounting slots are provided on the side wall of the inner cylinder. A slider that is rotatably connected to the end of the support rod is slidably provided in the mounting slot. A reset post that passes through the corresponding slider is fixed to the end of the mounting slot away from the swing frame. A reset spring with its two ends abutting against the mounting slot and the slider is sleeved in the middle section of the reset post. When the inner cylinder moves toward the roller, the roller squeezes the connecting rod, causing the connecting rod to drive the swing frame to swing and causing the slider to slide along the mounting slot to compress the reset spring. When the inner cylinder moves in the opposite direction, the reset spring pushes the slider to move in the opposite direction, causing the pad to separate from the inner cylinder by the transmission of the connecting rod to support the incense stick inside the inner cylinder.

[0008] Preferably, a docking cylinder is fixed to the inner wall of the end of the roller away from its open end, and a clamping cylinder is fixed to the end of the inner cylinder near the docking cylinder. The clamping cylinder extends toward the inner cylinder and its opening faces the docking cylinder. The inner diameter of the clamping cylinder is larger than the outer diameter of the docking cylinder, so that the clamping cylinder is sleeved on the outside of the docking cylinder. The inner wall of the clamping cylinder is fixed with multiple sets of positioning heads. Each set of positioning heads includes two positioning heads symmetrically arranged with respect to the axis of the inner cylinder. The multiple sets of positioning heads correspond to multiple side wall angles of the inner cylinder. Each set of positioning heads is located at different angular positions, so that when the inner cylinder is inserted into the roller, it can be aligned and fitted with the corresponding docking hole through the positioning head without selecting the circumferential angle. The multiple sets of positioning heads are staggered and spaced along the axial direction of the clamping cylinder, so that only one set of positioning heads is arranged in any cross section of the clamping cylinder, so as to avoid multiple sets of positioning heads overlapping at the same axial position and causing component collision. The outer wall of the docking cylinder is provided with multiple docking holes that correspond to the positioning heads. The docking holes are arranged in an array along the axial direction of the docking cylinder, so that when the inner cylinder moves to different depths, each set of positioning heads is inserted into the docking hole at the corresponding position to lock the relative position between the inner cylinder and the roller, thereby fixing the opening size of the fragrance leakage hole.

[0009] Preferably, the inner wall of the clamping cylinder is fixed with a plurality of clamping posts, which are distributed correspondingly to the positioning head. The end of the clamping post extending into the corresponding positioning head is fixed with a clamping block. The inner diameter of the end of the positioning head is smaller than the outer diameter of the clamping block to prevent the positioning head from separating from the clamping post. The middle section of the clamping post is fitted with a positioning spring with its two ends respectively abutting against the inner wall of the clamping cylinder and the positioning head.

[0010] Preferably, the end of the clamping cylinder is fixed with a cap to close the end of the clamping cylinder and limit the depth of the docking cylinder extending into the clamping cylinder. The end of the docking cylinder is fixed with a spherical connector for guiding the docking cylinder to dock with the clamping cylinder. The end of the clamping cylinder extending outside the inner cylinder is fixed with a fixing plate to connect to the inner cylinder. The fixing plate has a conical surface at the end facing the docking cylinder. The diameter of the conical surface gradually increases from one end facing the docking cylinder to the other end. When the docking cylinder is misaligned, the end of the docking cylinder abuts against the conical surface and is blocked to indicate that the docking cylinder is misaligned.

[0011] Preferably, a V-shaped scraper is fixed at the connection of each side of the outer wall of the roller. The scraper is used to scrape the external spices into the roller, and a groove is opened in the middle of the scraper to allow the spices to pass through.

[0012] Preferably, the inner wall of the roller is provided with multiple limiting grooves corresponding to the connecting rod. The connecting rod is squeezed by the roller and limited by the limiting grooves to avoid displacement. The end of the reset column away from the reset spring is fixed with a limiting head. The diameter of the limiting head is larger than the diameter of the reset column to prevent the slider from separating from the reset column.

[0013] Preferably, the width of the end of the pad away from the swing frame is greater than the width of the end of the pad connected to the swing frame, so as to increase the supporting area of ​​the pad for the incense stick. A through groove is provided in the middle of the pad to reduce the weight of the pad and thus reduce the resistance of the pad when it swings with the swing frame.

[0014] Preferably, a pad strip is fixed to the wider end of the pad, the pad strip extends along the width direction of the pad, and the length of the pad strip is greater than the width of the wider end of the adjacent pad. The pad strip is made of elastic material so that the two ends of the adjacent pad strip fit together to fill the gap between the adjacent pads and prevent the incense stick from separating from the pad from the gap between the adjacent pads.

[0015] The present invention also provides a fragrance applicator, including a bracket, with a support frame fixed on both sides of the bracket, a mounting frame fixed on the top of the support frame, a processing frame fixed inside the mounting frame, a transmission component inside the processing frame, a plurality of rollers fixed on one side of the transmission component, and a support frame located on the transmission component fixed inside the processing frame, with the ends of the plurality of rollers located in the annular space between the support frame and the processing frame, and supported by the support frame and the processing frame.

[0016] Preferably, the mounting frame has a feeding groove at the bottom of the roller, and a funnel with a gradually decreasing width from top to bottom is fixed at the bottom of the feeding groove. The side wall of the mounting frame has an operating groove corresponding to one end of the transmission component. When the roller moves to the position corresponding to the operating groove with the transmission component, the loading and unloading operation is performed.

[0017] Using the above-mentioned fragrance rinsing machine and its fragrance rinsing roller, the inner cylinder is first inserted into the roller. The retaining sleeve at the end of the inner cylinder is sleeved on the outside of the docking cylinder at the end of the roller. Multiple sets of positioning heads on the inner wall of the retaining sleeve are engaged with the docking holes of the corresponding positions on the outer wall of the docking cylinder under the action of springs. Since the angle and orientation of each set of positioning heads correspond one-to-one with each side wall of the inner cylinder, the inner cylinder can be fully aligned and inserted at any circumferential angle without the need to select an angle. During the insertion process, the spherical joint at the end of the docking cylinder plays a guiding role in alignment. If the insertion is off-center, the end of the docking cylinder will be blocked by the conical surface of the fixing plate, prompting the operator to adjust and re-insert. Then, the inner cylinder is moved axially so that the overlapping area of ​​the roller leakage hole and the inner cylinder adjustment hole reaches the required value, that is, the opening size of the fragrance leakage hole is set. The positioning head then engages with the docking hole of the corresponding position to lock the position of the inner cylinder, thus completing the fragrance flow rate adjustment before processing. During processing, the transmission components drive multiple rollers to rotate synchronously. The V-shaped scraper at the edge of the outer wall of the roller scrapes the external fragrance as the roller rotates. The fragrance enters the inner cylinder through the leakage hole and fragrance leakage hole. The fragrance sticks in the inner cylinder cavity are supported by the pads at the ends of each swing frame. When the fragrance sticks need to be removed, the inner cylinder is moved axially. The inner wall of the roller squeezes the connecting rod that penetrates the inner cylinder. The connecting rod drives the swing frame to swing, so that the pads are lifted to support the fragrance sticks. At the same time, the connecting rod pushes the slider along the mounting groove through the support rod and compresses the return spring. When the inner cylinder is moved in the opposite direction, the squeezing is released, the return spring pushes the slider to return to its original position, and the pads fall back. The scraper can continuously feed the material when the roller rotates forward or backward. During processing, the spices that fall off fall into the funnel that gradually narrows from top to bottom through the feeding trough at the bottom of the installation frame, thus separating the broken materials from the finished product. When loading and unloading, the roller rotates to the position corresponding to the operating groove on the side wall of the installation frame. The operator picks up and puts out the spice sticks through the operating groove, completing one processing cycle.

[0018] The beneficial effects are as follows: 1. This invention makes the leakage holes on the inner cylinder wall correspond one-to-one with the adjustment holes on the inner cylinder wall, forming a fragrance leakage hole in the overlapping area of ​​the two, and setting a swing frame that penetrates the inner cylinder wall. The pads and connecting rods are fixed at both ends of the swing frame. The single action of axially moving the inner cylinder can make the adjustment hole misalign with the leakage hole. The overlapping area changes continuously with the amount of movement, and the opening size of the fragrance leakage hole is continuously adjusted accordingly. The amount of fragrance that can pass through can be set according to the specifications of the incense stick. At the same time, when the inner cylinder moves, the connecting rod drives the swing frame to swing, and the pads are lifted accordingly. When taking out the incense stick, it is not necessary to insert it into the inner cylinder to lift the incense stick. When the inner cylinder moves in the opposite direction, the pads automatically fall back. One axial movement completes the opening adjustment and incense stick lifting at the same time. The operation steps are few and the adjustment and incense taking are smoothly connected.

[0019] 2. By setting multiple sets of positioning heads on the inner wall of the clamping cylinder, each corresponding to a different angle of the inner cylinder's side wall, and opening docking holes at corresponding angles on the outer wall of the docking cylinder, when the inner cylinder is inserted into the roller, regardless of the circumferential angle, each set of positioning heads can be aligned with the docking hole at the corresponding position and inserted completely. Assembly can be completed without selecting the circumferential angle. At the same time, the multiple sets of positioning heads are staggered and spaced along the clamping cylinder axis, with only one set arranged in any cross-section, avoiding component collisions caused by overlapping multiple sets of positioning heads.

[0020] 3. By fitting the positioning head onto the locking post and equipping it with a positioning spring, when the inner cylinder shifts axially, the outer wall of the docking cylinder presses against the positioning head to overcome the spring force and retract. When it moves to the next docking hole position, the spring pushes the positioning head to extend and re-insert, realizing automatic switching between locking and shifting without manual unlocking. The locking head is prevented from separating from the locking post by the locking block at the end of the locking post and the end of the positioning head, ensuring reliable locking.

[0021] 4. By fixing V-shaped scrapers at the connection points on the outer walls of the drum, the two wings of the V-shaped scrapers open symmetrically, and the external fragrance can be scraped when the drum rotates forward or backward. The feeding is not restricted by the rotation of the drum. A through groove is opened in the middle of the scraper, and some fragrance passes through the groove to the scraper, avoiding the accumulation and obstruction of fragrance at the scraper and improving the continuity of feeding.

[0022] 5. By placing the ends of multiple rollers in the annular space between the support frame and the processing frame and supporting them by both, the end supports are stable and do not shift when the rollers rotate. The transmission components drive multiple rollers to rotate synchronously, realizing synchronous processing at multiple stations and improving the overall efficiency of the machine.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0027] See Figures 1-18 As shown, the present invention provides a fragrance spraying machine roller, including a roller 1 and an inner cylinder 2. The roller 1 is a hollow polygonal body, and the inner cylinder 2 is a hollow polygonal body adapted to the shape of the roller 1. The roller 1 is sleeved on the outside of the inner cylinder 2. Each side wall of the roller 1 corresponds to and fits against each other with the side wall of the inner cylinder 2. The inner cylinder 2 can move relative to the roller 1 along its own axis. Each side wall of the inner cylinder 2 is rotatably provided with a swing frame 3 that penetrates the inner cylinder 2 wall. The swing frame 3 can swing relative to the inner cylinder 2 around its rotation axis. The two ends of the swing frame 3 extend to the inner side of the cavity of the inner cylinder 2 and the outer side of the inner cylinder 2, respectively. The cylinder wall of roller 1 has multiple perforations 101, which penetrate the cylinder wall and are distributed along the side walls of roller 1. The cylinder wall of inner cylinder 2 has multiple adjustment holes 201, which are arranged one-to-one with the perforations 101. When inner cylinder 2 moves axially relative to roller 1, the adjustment holes 201 are misaligned relative to the perforations 101 as inner cylinder 2 moves. The overlapping area of ​​the perforation 101 and the corresponding adjustment hole 201 forms the perforation hole for fragrance to pass through. The amount of movement of inner cylinder 2... The larger the opening, the larger the overlapping area of ​​the leakage hole 101 and the adjustment hole 201, the larger the opening of the fragrance leakage hole, and the more fragrance passes through the fragrance leakage hole per unit time. When the inner cylinder 2 moves in the opposite direction, the overlapping area decreases, the opening of the fragrance leakage hole shrinks accordingly, and the amount of fragrance passing through decreases. At this time, the inner cylinder 2 stays at a set depth along the axial direction in the drum 1, and the adjustment hole 201 and the leakage hole 101 maintain the overlapping area corresponding to the position of the inner cylinder 2. The fragrance leakage hole allows the fragrance to pass through with a fixed opening size, and the fragrance flow rate remains stable.

[0028] The swing frame 3 penetrates the wall of the inner cylinder 2 and can swing relative to the inner cylinder 2 around its rotation axis. A pad 303 is fixed to the end of the swing frame 3 located inside the cavity of the inner cylinder 2. The pad 303 extends along the side wall of the inner cylinder 2 and is used to support the incense stick inside the cavity of the inner cylinder 2. The pad 303 rises or falls with the swing of the swing frame 3. A connecting rod 301 is fixed to the other end of the swing frame 3. The connecting rod 301 penetrates the wall of the inner cylinder 2. The end of the connecting rod 301 located outside the inner cylinder 2 extends between the outer wall of the inner cylinder 2 and the inner wall of the roller 1. The connecting rod 301 moves with the swing of the swing frame 3, and the side wall of the inner cylinder 2 opens... Multiple mounting slots 202 are provided, which extend along the axial direction of the inner cylinder 2. A slider 203 is slidably mounted in the mounting slot 202. A retaining plate 204 is fixed on both sides of the slider 203. The retaining plate 204 is attached to the side wall of the inner cylinder 2 and slides along the inner cylinder 2 together with the slider 203. The slider 203 can slide back and forth along the length direction of the mounting slot 202. A support rod 302 is rotatably mounted on the end of the connecting rod 301 located in the inner cylinder 2. The end of the support rod 302 is rotatably connected to the slider 203. When the connecting rod 301 moves, it pushes the slider 203 to slide along the mounting slot 202 via the support rod 302. A reset post 205 is fixed at the end of the mounting groove 202 away from the swing frame 3. The reset post 205 passes through the slider 203. The slider 203 is sleeved on the reset post 205 and can slide along the reset post 205. A reset spring 206 is sleeved in the middle section of the reset post 205. The two ends of the reset spring 206 abut against the groove wall of the mounting groove 202 away from the swing frame 3 and the slider 203, respectively. When the slider 203 slides along the mounting groove 202 away from the swing frame 3, it compresses the reset spring 206. When the reset spring 206 resets, it pushes the slider 203 to slide along the mounting groove 202 towards the swing frame 3. When the inner cylinder 2 moves toward the drum 1, the end of the connecting rod 301 located on the outside of the inner cylinder 2 is squeezed by the inner wall of the drum 1. The connecting rod 301 drives the swing frame 3 to swing around its rotation axis. The pad 303 swings with the swing frame 3. At the same time, the connecting rod 301 pushes the slider 203 to slide along the mounting groove 202 via the support rod 302. The slider 203 compresses the return spring 206. When the inner cylinder 2 moves in the opposite direction, the squeeze of the drum 1 on the connecting rod 301 is released. The return spring 206 pushes the slider 203 to slide in the opposite direction. The slider 203 drives the swing frame 3 to swing in the opposite direction via the support rod 302 and the connecting rod 301. The pad 303 swings with the swing frame 3 and separates from the inner cylinder 2 to support the incense stick in the cavity of the inner cylinder 2. The inner wall of the roller 1 is provided with multiple limiting grooves 102, which are correspondingly arranged with the connecting rod 301. The rod body of the connecting rod 301 is located in the corresponding limiting groove 102. When the inner cylinder 2 moves, the connecting rod 301 moves along the limiting groove 102. The groove wall of the limiting groove 102 restricts the connecting rod 301 from deviating, so that the connecting rod 301 always maintains the predetermined trajectory. The end of the reset column 205 away from the reset spring 206 is fixed with a limiting head 207 (see details). Figure 10 The diameter of the limiting head 207 is larger than the diameter of the reset post 205. When the slider 203 slides along the reset post 205 to the limiting head 207, the limiting head 207 abuts against the slider 203, preventing the slider 203 from continuing to slide, thus avoiding separation between the slider 203 and the reset post 205. The width of the end of the pad 303 away from the swing frame 3 is greater than the width of the end of the pad 303 connected to the swing frame 3. When the pad 303 swings with the swing frame 3, its wider end forms a larger supporting surface for the incense stick. To prevent the incense stick from slipping off the end of the pad 303 away from the swing frame 3, a through groove 304 is provided in the middle of the pad 303. The through groove 304 reduces the solid material used in the pad 303, reducing its weight and thus reducing the resistance when the pad 303 swings with the swing frame 3. A pad strip 305 is fixed to the wider end of the pad 303. The pad strip 305 extends along the width direction of the pad 303, and its length is greater than the width of the wider end of the adjacent pad 303. The pad strip 305 is made of elastic material, and the ends of the pad strips 305 on adjacent pads 303 fit together to fill the gap between adjacent pads 303, preventing the incense stick from leaking out from the gap between adjacent pads 303. The inner cylinder 2 stays in the roller 1 along the axial direction at a set position. The connecting rod 301 maintains a predetermined trajectory under the constraint of the limiting groove 102. The slider 203 stays in the mounting groove 202 at a position corresponding to the position of the inner cylinder 2. The pad 303 supports the incense stick in the cavity of the inner cylinder 2 at a predetermined angle under the drive of the swing frame 3. The gap between adjacent pads 303 is filled by the pads 305 that fit together. The incense stick remains stable under the support of the pads 303 and the filling effect of the pads 305.

[0029] A docking cylinder 104 is fixed to the inner wall of the end of the roller 1 away from the opening end. The docking cylinder 104 extends from the end of the roller 1 along the axial direction of the roller 1 towards the inner cylinder 2. The docking cylinder 104 is fixed with the roller 1. A clamping cylinder 208 is fixed to the end of the inner cylinder 2 near the docking cylinder 104. The clamping cylinder 208 extends along the axial direction of the inner cylinder 2 towards the inner cylinder 2. The opening of the clamping cylinder 208 faces the docking cylinder 104. The inner diameter of the clamping cylinder 208 is larger than the outer diameter of the docking cylinder 104. The clamping cylinder 208 is sleeved on the outside of the docking cylinder 104. The docking cylinder 104 extends into the clamping cylinder 208. When the inner cylinder 2 moves axially relative to the roller 1, the docking cylinder 104 extends into the clamping cylinder 208 from the opening end of the clamping cylinder 208 or exits from the clamping cylinder 208. The clamping cylinder 208 and the docking cylinder 104 slide relative to each other axially. The depth of the docking cylinder 104 extending into the clamping cylinder 208 varies with the amount of movement of the inner cylinder 2. Multiple sets of positioning heads 209 are fixed to the inner wall of the clamping cylinder 208. Each set of positioning heads 209 includes two positioning heads 209 symmetrically arranged with the axis of the inner cylinder 2 as the center. The multiple sets of positioning heads 209 correspond one-to-one with multiple side walls of the inner cylinder 2. Each set of positioning heads 209 is located at different angular positions. The outer wall of the docking cylinder 104 is provided with multiple docking holes 104a that correspond to and cooperate with the positioning heads 209. The docking holes 104a are arrayed along the axial direction of the docking cylinder 104. The position of each docking hole 104a along the circumference of the docking cylinder 104 corresponds one-to-one with the angular position of each set of positioning heads 209. When the inner cylinder 2 is inserted into the roller 1, regardless of the circumferential angle of the inner cylinder 2, each set of positioning heads 209 can be aligned and cooperate with the docking hole 104a at the corresponding position. All positioning heads 209 are inserted into the corresponding docking hole 104a. The inner cylinder 2 can be inserted without selecting the circumferential angle.

[0030] Multiple sets of positioning heads 209 are staggered and spaced along the axial direction of the clamping cylinder 208, so that only one set of positioning heads 209 is arranged in any cross-section of the clamping cylinder 208. The multiple sets of positioning heads 209 are not overlapped at the same axial position to avoid component collisions caused by the overlapping of the axial positions of the positioning heads 209. The outer wall of the docking cylinder 104 is provided with multiple docking holes 104a that correspond to and cooperate with the positioning heads 209. The docking holes 104a are arrayed along the axial direction of the docking cylinder 104, and the position of each docking hole 104a along the circumference of the docking cylinder 104 corresponds one-to-one with the angular orientation of each set of positioning heads 209. The inner cylinder 2 moves relative to the roller 1 to different positions. At the set depth, each set of positioning heads 209 moves axially along with the clamping cylinder 208. When they move to the position corresponding to the docking hole 104a on the docking cylinder 104, the positioning head 209 is inserted into the corresponding docking hole 104a, locking the relative position between the inner cylinder 2 and the roller 1, thereby fixing the overlapping area of ​​the leakage hole 101 and the adjustment hole 201, that is, fixing the opening size of the leakage hole. The inner cylinder 2 stays at the set depth in the roller 1. Each set of positioning heads 209 in the clamping cylinder 208 is inserted into the docking hole 104a at the corresponding position on the outer wall of the docking cylinder 104. The relative position between the inner cylinder 2 and the roller 1 is locked, and the opening size of the leakage hole remains fixed.

[0031] Multiple locking posts 210 are fixed to the inner wall of the clamping cylinder 208. The locking posts 210 are distributed correspondingly to the positioning heads 209, with one locking post 210 corresponding to each positioning head 209. The locking posts 210 extend in a direction perpendicular to the inner wall of the clamping cylinder 208. The positioning head 209 is sleeved on the corresponding locking post 210 and can slide back and forth along the length of the locking post 210. The end of the positioning head 209 away from the inner wall of the clamping cylinder 208 extends out of the inner wall of the clamping cylinder 208 and faces the outer wall of the docking cylinder 104. A locking block 211 is fixed to the end of the locking post 210 that extends into the corresponding positioning head 209. The locking block 211 is located inside the positioning head 209, and the inner diameter of the end of the positioning head 209 is smaller than the outer diameter of the locking block 211. When the positioning head 209 slides along the locking post 210 toward the locking block 211 to its limit position, the end of the positioning head 209 abuts against the locking block 211. The locking block 211 prevents the positioning head 209 from continuing to slide, so as to prevent the positioning head 209 from separating from the locking post 210. A positioning spring 210a is sleeved in the middle section of the locking post 210. One end of the positioning spring 210a abuts against the inner wall of the locking cylinder 208, and the other end abuts against the positioning head 209. The positioning spring 210a applies an elastic force to the positioning head 209 in the direction of the locking block 211, so that the end of the positioning head 209 is pressed against the locking block 211 under the push of the positioning spring 210a, and maintains the tendency to extend toward the outer wall of the docking cylinder 104. When the docking hole 104a on the outer wall of the docking cylinder 104 is opposite to the positioning head 209, the positioning head 209 extends into the docking hole 104a under the push of the positioning spring 210a, and the positioning head 209 and the docking hole 104a are engaged. When the inner cylinder 2 moves axially relative to the roller 1, the wall surface of the outer wall of the docking cylinder 104 between adjacent docking holes 104a presses against the end of the positioning head 209. The positioning head 209 overcomes the elastic force of the positioning spring 210a and retracts along the locking post 210 towards the inner wall of the locking cylinder 208. The positioning spring 210a is compressed. When the positioning head 209 moves with the inner cylinder 2... When the positioning head 209 reaches the position corresponding to the next docking hole 104a, the positioning spring 210a resets and pushes the positioning head 209 to extend along the locking post 210 toward the locking block 211. The end of the positioning head 209 extends into the corresponding docking hole 104a again, completing the shifting insertion. Each positioning head 209 is inserted into the docking hole 104a at the corresponding position on the outer wall of the docking cylinder 104 under the push of the corresponding positioning spring 210a. Each locking block 211 abuts against the end of the corresponding positioning head 209. The positioning head 209 and the locking post 210 remain connected, and the relative position of the inner cylinder 2 and the roller 1 remains locked.

[0032] A cap 208a is fixed to the end of the clamping cylinder 208 away from its open end. The cap 208a closes the end of the clamping cylinder 208 away from the end of the docking cylinder 104. The docking cylinder 104 extends into the clamping cylinder 208 from its open end and extends further into the clamping cylinder 208. When the docking cylinder 104 extends into the clamping cylinder 208 to its maximum depth, the end of the docking cylinder 104 abuts against the cap 208a. The cap 208a limits the depth of the docking cylinder 104 into the clamping cylinder 208, that is, it limits the maximum extension of the docking cylinder 104 when the inner cylinder 2 moves relative to the roller 1. The end of the docking cylinder 104 that extends into the clamping cylinder 208 is fixed with a spherical connector 104b. The connector 104b is spherical and located at the end of the docking cylinder 104 facing the inside of the clamping cylinder 208. When the docking cylinder 104 is inserted into the clamping cylinder 208, the connector 104b enters the opening of the clamping cylinder 208 before the end of the docking cylinder 104. The outer surface of the connector 104b matches the inner wall of the opening of the clamping cylinder 208, guiding the docking cylinder 104 to dock with the clamping cylinder 208, so that the end of the docking cylinder 104 smoothly enters the clamping cylinder 208 along the axial direction of the clamping cylinder 208. The end of the retainer 208 extending outside the inner cylinder 2 is fixed with a fixing plate 208b (see details). Figure 8The fixing plate 208b is fixedly connected to the inner cylinder 2, and the clamping sleeve 208 is fixedly connected to the inner cylinder 2. A conical surface 208c is provided on the end of the fixing plate 208b facing the docking sleeve 104. The conical surface 208c is located at the end of the fixing plate 208b facing the docking sleeve 104 and extends along the periphery of the opening of the clamping sleeve 208. The diameter of the conical surface 208c gradually increases from one end facing the docking sleeve 104 to the other end; that is, the diameter of the conical surface 208c is smaller at the end facing the docking sleeve 104 and larger at the end away from the docking sleeve 104. When the docking sleeve 208 is inserted into the docking sleeve 104, the docking... The head 104b guides the end of the docking cylinder 104 to enter from the smaller diameter end of the conical surface 208c. The end of the docking cylinder 104 slides into the opening of the clamping cylinder 208 along the conical surface 208c. The docking cylinder 104 smoothly extends into the clamping cylinder 208. When the docking cylinder 104 is misaligned, the end of the docking cylinder 104 is not aligned with the opening of the clamping cylinder 208. The end of the docking cylinder 104 abuts against the conical surface 208c and cannot continue to extend due to the obstruction of the conical surface 208c. This serves as a reminder to the operator that the docking cylinder 104 is misaligned. The operator adjusts the relative position of the docking cylinder 104 and the clamping cylinder 208 and then reinserts it.

[0033] V-shaped scrapers 103 are fixed at the joints on each side of the outer wall of the roller 1. The scrapers 103 extend along the joints between adjacent sides of the outer wall of the roller 1 and are fixedly connected to the roller 1. The scrapers 103 are V-shaped, with their two wings opening outward from the outer wall of the roller 1, and the ends of the two wings facing away from the outer wall of the roller 1. The V-shaped openings of the scrapers 103 face outward from the roller 1. When the roller 1 rotates, the scrapers 103 rotate synchronously with the roller 1. During the rotation, the two wings of the scrapers 103 scrape the external fragrance located outside the outer wall of the roller 1, scraping the external fragrance from one side of the outer wall of the roller 1 and guiding the external fragrance towards the cylinder wall of the roller 1. When the external fragrance scraped by the scrapers 103 moves to the drain hole 101 in the cylinder wall of the roller 1, the external fragrance enters the cylinder wall of the roller 1 through the drain hole 101. The fragrance enters the cavity of the inner cylinder 2 through the overlapping area of ​​the leakage hole 101 and the adjustment hole 201. The middle part of the scraper 103 has a leakage groove 103a, which passes through the scraper 103. When the scraper 103 scrapes the external fragrance, some of the fragrance passes through the leakage groove 103a and then through the scraper 103, preventing the external fragrance from accumulating and obstructing at the scraper 103. This allows the external fragrance to move smoothly towards the leakage hole 101. During the rotation of the roller 1, each V-shaped scraper 103 rotates synchronously with the roller 1. The two wings of the scraper 103 continuously scrape the external fragrance. Some of the external fragrance passes through the leakage groove 103a and then through the scraper 103. The external fragrance continuously enters the cavity of the inner cylinder 2 through the leakage hole 101 and the fragrance leakage hole. When the roller 1 rotates forward or backward, the V-shaped scraper 103 can scrape the external fragrance. A fragrance applicator includes a support frame 4. Brackets 404 are fixed to both sides of the support frame 4, respectively, and remain fixed with the support frame 4. A mounting frame 401 is fixed to the top of the brackets 404, and remains fixed with the brackets 404. A processing frame 403 is fixed inside the mounting frame 401, and remains fixed with the mounting frame 401. A transmission component 405, which can be a chain, is provided inside the processing frame 403 and is connected to multiple rollers 1. The multiple rollers 1 are respectively connected to the transmission component 405, and the multiple rollers 1 move along the transmission component 405. The moving parts 405 are arranged sequentially in the direction of extension. When the transmission part 405 rotates, it drives multiple rollers 1 to rotate synchronously. A support frame 403a is also fixed inside the processing frame 403. The support frame 403a is located on one side of the transmission part 405 and is fixed inside the processing frame 403. An annular space is formed between the support frame 403a and the processing frame 403. The ends of multiple rollers 1 are located in the annular space between the support frame 403a and the processing frame 403. The ends of each roller 1 extend into the annular space and are supported by the support frame 403a and the processing frame 403. When the roller 1 rotates, the ends of the roller 1 rotate in the annular space. The support frame 403a and the processing frame 403 support the ends of the roller 1 and keep the position of the roller 1 stable during rotation.

[0034] A feeding groove 406 is provided at the bottom of the mounting frame 401 corresponding to the bottom of the roller 1. The feeding groove 406 penetrates the bottom of the mounting frame 401 and is located below the roller 1, opposite to the bottom of the roller 1. A funnel 407 is fixed to the bottom of the mounting frame 401 corresponding to the feeding groove 406. The funnel 407 is fixed to the bottom of the mounting frame 401 and located below the feeding groove 406. The funnel 407 is connected to the feeding groove 406. The width of the funnel 407 gradually decreases from top to bottom. The upper opening of the funnel 407 corresponds to the feeding groove 406, and the lower opening of the funnel 407 is smaller than the upper opening. An operating groove 402 is provided on the side wall of the mounting frame 401, penetrating the side wall of the mounting frame 401. The operating groove 402 is correspondingly set at one end of the transmission component 405. The end of the transmission component 405 is located at the corresponding position of the operating groove 402. The operator operates the end of the transmission component 405 through the operating groove 402. The roller 1 moves synchronously with the transmission component 405 under the drive of the transmission component 405. When the roller 1 rotates with the transmission component 405 to the position corresponding to the operating groove 402, the operator performs loading and unloading operations on the roller 1 through the operating groove 402. When processing incense sticks, the spices in the roller 1 fall from the roller 1 through the feeding groove 406 into the funnel 407. After being gathered through the funnel 407 with a gradually decreasing width, they are discharged from the lower opening of the funnel 407. When loading and unloading, the operator puts the incense sticks into the roller 1 through the operating groove 402.

[0035] Using the above structure, in use, the inner cylinder 2 is first inserted into the roller 1. The retaining sleeve 208 at the end of the inner cylinder 2 is sleeved on the outside of the docking sleeve 104 at the end of the roller 1. Multiple sets of positioning heads 209 on the inner wall of the retaining sleeve 208 are inserted and engaged with the corresponding docking holes 104a on the outer wall of the docking sleeve 104 under the action of springs. Since the angle and orientation of each set of positioning heads 209 correspond one-to-one with each side wall of the inner cylinder 2, the inner cylinder 2 can be fully aligned and inserted at any circumferential angle without the need to select an angle. During the insertion process, the docking sleeve... The spherical connector 104b at the end of 104 serves as a guide for alignment. If it is misaligned, the end of the connecting cylinder 104 will be blocked by the conical surface 208c of the fixing plate 208b, prompting the operator to adjust and re-insert it. Then, the inner cylinder 2 is moved axially so that the overlapping area of ​​the leakage hole 101 of the roller 1 and the adjustment hole 201 of the inner cylinder 2 reaches the required value, that is, the opening size of the fragrance leakage hole is set. The positioning head 209 then engages with the corresponding connecting hole 104a to lock the position of the inner cylinder 2, thus completing the fragrance flow rate adjustment before processing. During processing, the transmission component 405 drives multiple rollers 1 to rotate synchronously. The V-shaped scraper 103 at the edge of the outer wall of the roller 1 scrapes the external fragrance as the roller 1 rotates. The fragrance enters the inner cylinder 2 through the leakage hole 101 and the fragrance leakage hole. The fragrance strips in the inner cylinder 2 are supported by the pads 303 at the ends of each swing frame 3. When the fragrance strips need to be removed, the inner cylinder 2 is moved axially. The inner wall of the roller 1 squeezes the connecting rod 301 that penetrates the inner cylinder 2. The connecting rod 301 drives the swing frame 3 to swing, so that the pads 303 are lifted to support the fragrance strips. At the same time, the connecting rod 301 pushes the slider 203 along the mounting groove 202 through the support rod 302 and compresses the return spring 206. When the inner cylinder 2 is moved in the opposite direction, the compression is released, the return spring 206 pushes the slider 203 to return to its original position, and the pads 303 fall back. The scraper 103 can continuously feed when the roller 1 rotates forward or backward. During processing, the spices that fall off fall into the funnel 407 that gradually narrows from top to bottom through the feeding groove 406 at the bottom of the mounting frame 401, thus separating the broken materials from the finished product. When loading and unloading, the roller 1 rotates to the position corresponding to the operating groove 402 on the side wall of the mounting frame 401. The operator picks up and puts out the spice strips through the operating groove 402, thus completing one processing cycle. By aligning the leakage holes 101 on the wall of the roller 1 with the adjustment holes 201 on the wall of the inner cylinder 2, and forming a leakage hole in the overlapping area of ​​the two, and by setting a swing frame 3 that penetrates the wall of the inner cylinder 2, and fixing a pad 303 and a connecting rod 301 at both ends of the swing frame 3, the single action of axially moving the inner cylinder 2 can cause the adjustment hole 201 to be misaligned relative to the leakage hole 101. The overlapping area changes continuously with the amount of movement, and the size of the leakage hole opening is continuously adjusted accordingly. The amount of incense that can pass through can be set according to the specifications of the incense stick. At the same time, when the inner cylinder 2 moves, the connecting rod 301 drives the swing frame 3 to swing, and the pad 303 is lifted accordingly. When taking out the incense stick, it is not necessary to insert it into the inner cylinder 2 to lift the incense stick. When the inner cylinder 2 moves in the opposite direction, the pad 303 automatically falls back. One axial movement completes the opening adjustment and incense stick lifting at the same time. The operation steps are few, and the adjustment and incense taking are smoothly connected. By setting multiple sets of positioning heads 209 on the inner wall of the clamping cylinder 208, which correspond one-to-one with the angles of multiple side walls of the inner cylinder 2 and are located at different angular positions, and opening docking holes 104a at the corresponding angular positions on the outer wall of the docking cylinder 104, when the inner cylinder 2 is inserted into the roller 1, regardless of the circumferential angle, each set of positioning heads 209 can be aligned with the docking holes 104a at the corresponding position and inserted completely, so that assembly can be completed without selecting the circumferential angle. At the same time, the multiple sets of positioning heads 209 are staggered and spaced along the axial direction of the clamping cylinder 208, and only one set is arranged in any cross section, avoiding the collision of parts caused by the overlapping arrangement of multiple sets of positioning heads 209. By fitting the positioning head 209 onto the locking post 210 and equipping it with a positioning spring 210a, when the inner cylinder 2 shifts axially, the outer wall of the docking cylinder 104 presses against the positioning head 209 to overcome the spring force and retract. When it moves to the next docking hole 104a position, the spring pushes the positioning head 209 to extend and re-insert, achieving automatic switching between locking and shifting without manual unlocking. This is achieved through the locking block 211 at the end of the locking post 210 (see details). Figure 9 The positioning head 209 abuts against the end of the positioning head 209 to limit its movement, preventing the positioning head 209 from separating from the locking post 210, ensuring reliable locking. By fixing V-shaped scrapers 103 at the connection points on the outer walls of the roller 1, the two wings of the V-shaped scrapers 103 are symmetrically opened, and the external fragrance can be scraped when the roller 1 rotates forward or backward. The feeding is not restricted by the rotation of the roller 1. A through groove 103a is opened in the middle of the scraper 103, and some fragrance passes through the scraper 103 through the groove 103a, which avoids the fragrance from accumulating and blocking at the scraper 103 and improves the continuity of feeding. By placing the ends of multiple rollers 1 within the annular space between the support frame 403a and the processing frame 403 and supporting them, the end supports of the rollers 1 are stable and do not shift when they rotate. The transmission component 405 drives the multiple rollers 1 to rotate synchronously, thereby achieving synchronous processing at multiple workstations and improving the overall efficiency of the machine.
