Description

Technical Field

[0001] This invention relates to the field of incense making, specifically to an integrated machine for threading and shaping incense sticks and its processing method. Background Technology

[0002] During the incense-making process, bamboo skewers must first be inserted into the incense-extruding station, and then shaped by the extrusion of incense clay. At the moment of extrusion, the incense clay exerts an axial thrust on the bamboo skewers. If the ends of the bamboo skewers are not restrained, the skewers will move axially, and the length of the exposed section of the bamboo skewers, i.e., the incense foot, will be out of control.

[0003] To address this, existing incense-making machines are equipped with baffles at the incense-extrusion station. During incense extrusion, the baffles press against the ends of the bamboo sticks, locking the axial position of the bamboo sticks. After the incense extrusion is completed, the baffles retract, and the bamboo sticks carry the formed incense sticks out. The length of the incense stick is determined by the distance from the baffle positioning surface to the incense-extrusion station. The length of the incense stick changes depending on the position of the baffle.

[0004] In existing incense-making machines, the position of the baffle is usually adjusted manually. The operator loosens the baffle fixing parts, moves the baffle to the target position, and then tightens the fixing parts to set the incense stick length. However, every time the incense type is changed or the incense stick specifications are adjusted, the machine must be stopped and the fixing parts must be loosened and tightened manually, and repeated trial extrusions must be performed for calibration. The adjustment efficiency is low, and the adjustment accuracy depends on the operator's experience. It is difficult to guarantee the consistency of incense stick length between different batches. Secondly, the baffle bears the axial impact load transmitted by the bamboo stick during the incense extrusion process. If the locking force of the fixing parts is insufficient, the baffle is prone to positional drift under impact, causing the incense stick length to gradually become inaccurate during continuous production, requiring frequent machine stops for verification.

[0005] To improve the accuracy and efficiency of baffle position adjustment, some incense-making machines are equipped with a separate drive mechanism for the baffle, i.e., an independent motor and matching transmission structure are added to drive the baffle to move and achieve automatic adjustment. Although this solution eliminates manual operation, baffle position adjustment is an intermittent auxiliary action, which takes much less time than the main incense extrusion process. Setting up a separate complete drive mechanism for it leads to an increase in the number of parts, a bulky structure, increased costs, and increased control complexity, which contradicts the overall requirement of a simple structure and reliable operation for incense-making machines.

[0006] Therefore, there is a need for an integrated machine for incense stick making that can automatically adjust the position of the baffle without adding a new independent power source. This machine would allow both the baffle and the adjustment to be completed by the same power source through a directional switching method, thus balancing the automation of incense stick length adjustment with the simplicity of the overall machine structure. Summary of the Invention

[0007] The purpose of this invention is to provide an integrated machine for skewering and shaping incense sticks and its processing method in order to solve the above-mentioned problems. The machine uses a single motor to switch between forward and reverse directions to complete the switching between two working conditions: blocking bamboo skewers and adjusting the length of the incense sticks. This avoids the need to set up a separate drive mechanism for adjusting the position of the baffle, so that the automatic adjustment of the length of the incense sticks can be achieved without adding an independent power source. The machine has fewer parts and a simple structure, as detailed below.

[0008] To achieve the above objectives, the present invention provides the following technical solution: The present invention provides an integrated machine for making incense sticks and shaping, comprising a machine housing, a movable frame, a motor, a drive gear and a driven gear. The movable frame is slidably disposed on the top of the machine housing. The motor is driven and connected to the drive gear. The drive gear meshes with the driven gear, and the drive gear is eccentrically driven and connected to the movable frame. When the motor rotates forward, it drives the movable frame to slide back and forth through the drive gear, and causes the movable frame to press against the end of the bamboo stick when squeezing incense. The passive gear is coaxially provided with a synchronizing cylinder at its bottom. A positioning block is rotatably provided on the wall of the synchronizing cylinder. A connecting cylinder is sleeved inside the synchronizing cylinder. The connecting cylinder has a groove for the positioning block to extend into. The positioning block only abuts against the groove and drives the connecting cylinder to rotate when rotating in one direction. When rotating in the opposite direction, the positioning block disengages from the groove. A worm is provided at the bottom of the connecting cylinder. A screw is rotatably provided inside the housing. A worm wheel that meshes with the worm is fixed at the end of the screw. A guide plate is threadedly provided on the screw. An adjusting plate is inclined on one side of the guide plate. A strip plate is slidably provided at the bottom of the movable frame. An adjusting plate that fits against the adjusting plate is provided at the top of the strip plate. When the motor reverses, it drives the active gear to rotate and causes the passive gear to rotate in the opposite direction, thereby driving the connecting cylinder to rotate. The worm gear drives the screw to rotate, causing the guide plate to move along the screw axis. The adjusting plate drives the strip plate to slide relative to the movable frame to adjust the reference position of the movable frame, thereby adjusting the length of the incense stick.

[0009] Preferably, the top of the drive gear is eccentrically provided with a rotating shaft, the middle section of the rotating shaft is provided with a connecting rod, the other end of the connecting rod is provided with a slider, the top of the housing is provided with a slide rail, the slider is slidably disposed inside the slide rail, the movable frame is fixed to the top of the slider for transmission connection with the drive gear, the end of the movable frame is provided with a connecting plate, the middle of the connecting plate is provided with a transverse groove parallel to the sliding direction of the slider, the strip plate is provided at the bottom of the connecting plate for connection with the movable frame, the middle of the strip plate is provided with a strip groove perpendicular to the extension direction of the transverse groove, multiple fixed cylinders are provided through the overlap of the strip groove and the transverse groove, the bottom of the fixed cylinder is provided with the same fixed plate, the top of the fixed cylinder is provided with a buckle plate with a diameter larger than the opening width of the transverse groove and the strip groove, and the bottom of the strip plate is provided with a baffle for preventing the axial movement of the bamboo skewer.

[0010] Preferably, a sliding rod is provided within the strip groove along its extension direction. The sliding rod passes through a corresponding fixed cylinder, and a spring is fitted on the side of the sliding rod away from the baffle. One end of the spring abuts against the inner wall of the strip groove away from the baffle, and the other end abuts against the outer wall of the adjacent fixed cylinder. The fixed cylinder is positioned along the extension direction of the strip groove by a transverse groove, so that the strip plate can only slide relative to the movable frame along the extension direction of the strip groove. When the adjusting plate presses against the adjusting plate, it compresses the spring and drives the strip plate to slide relative to the movable frame along the extension direction of the strip groove, causing the baffle to follow the strip groove. The plate moves to adjust the distance between the baffle and the end of the bamboo stick, thereby adjusting the length of the incense stick. The elastic force of the spring keeps the adjusting plate in contact with the adjusting plate. When the adjusting plate moves in the opposite direction, the strip plate follows synchronously with the spring to achieve bidirectional adjustment of the length of the incense stick. The middle section of the movable frame is a frame that bends downward and is parallel to the side wall of the machine casing. An extension frame is fixed to the outer wall of the machine casing corresponding to the middle section of the movable frame. The middle section of the movable frame has a support groove that slides with the extension frame. The movable frame is supported by the extension frame through the support groove to ensure the stability of the frame during the reciprocating movement of the movable frame.

[0011] Preferably, a support plate is fixed to the side wall of the housing near the screw, the end of the screw is rotatably connected to the support plate to be rotatably mounted on the housing, and a guide frame is fixed to the end of the support plate facing the screw. The guide frame passes through the guide plate, and the guide plate is limited by the guide frame and moves along the screw axis when the screw rotates.

[0012] Preferably, a rotating frame is fixed at the bottom of the top of the housing corresponding to the bottom of the driven gear, and a limiting plate is fixed on the outer wall of the middle section of the connecting cylinder. The limiting plate is rotatably connected to the middle of the rotating frame and supported by the rotating frame.

[0013] Preferably, the outer wall of the synchronizing cylinder is provided with an installation groove, and the end of the positioning block is rotatably provided with a support column. The support column is vertically fixed to the inner end of the installation groove. The positioning block is rotatably positioned in the installation groove through the support column. The positioning block is a triangular pyramidal block with one side being an inclined surface and the other side being a positioning surface. The positioning surface abuts against the side wall of the buckle groove to drive the connecting cylinder to rotate synchronously. When the inclined surface abuts against the buckle groove, it is squeezed and rotates around the support column to avoid the buckle groove, so as to separate the rotation action of the connecting cylinder from that of the driven gear.

[0014] Preferably, the positioning block has a positioning section on one side, which extends to the other side of the mounting groove. The positioning section is made of metal. A magnetic block is fixed in the mounting groove near the positioning section. The magnetic block magnetically engages with the positioning section so that after the positioning block is squeezed by the buckle groove and rotates around the support to avoid it, the magnetic force drives the positioning block to reset, allowing the positioning block to be reinserted into the buckle groove. When the synchronous cylinder rotates in the abutting direction, the positioning surface can abut against the side wall of the buckle groove, maintaining the unidirectional abutment of the positioning block against the buckle groove.

[0015] Preferably, the housing has a laterally extending through groove facing the baffle, the through groove being used to accommodate the adjustment plate passing through, and a protective cover is fixed to the outer wall of the top of the housing corresponding to the driven gear and the driving gear, the protective cover having a laterally extending clearance groove corresponding to the connecting rod, the clearance groove being used to accommodate the connecting rod passing through.

[0016] Preferably, a feeding hopper is fixed to the top of the housing, a skewer holder is fixed to the side of the housing facing the baffle, a feeding pipe is provided between the feeding hopper and the skewer holder, a partition for sealing the housing is fixed to the side of the housing away from the skewer holder, a ventilation groove is provided in the middle of the partition, a fixing rod is fixed to the side of the worm gear away from the screw, and the end of the fixing rod is rotatably disposed on the inner wall of the partition to support the other side of the screw and the worm gear.

[0017] The processing method of the incense-making stick-threading and shaping integrated machine includes the following steps: a. Insert the bamboo skewer into the skewer-insertion station, so that the end of the bamboo skewer is located in the fragrance-extrusion station. The motor rotates forward and drives the movable frame to slide back and forth through the drive gear. When the fragrance is extruded, the movable frame presses against the end of the bamboo skewer to lock the axial position of the bamboo skewer, and at the same time the fragrance is extruded and shaped. b. After the incense is extruded, the movable frame retracts, and the bamboo stick moves the formed incense stick out. When it is necessary to adjust the length of the incense stick, the motor reverses, and the active gear drives the passive gear to rotate in the opposite direction. The positioning block abuts against the buckle groove and drives the connecting cylinder to rotate. The worm gear and worm wheel drive the screw to rotate, so that the guide plate moves along the screw axis. The adjusting plate drives the strip plate to slide relative to the movable frame, adjusting the positioning reference position of the movable frame, and then adjusting the length of the incense stick. After the adjustment is completed, the motor resumes forward rotation and the incense extrusion begins again.

[0018] The beneficial effects are as follows: 1. This invention uses a motor as both the reciprocating drive source for the movable frame and the drive source for adjusting the position of the baffle. When the motor rotates forward, it drives the movable frame to slide back and forth via the eccentric transmission of the active gear, and presses against the end of the bamboo stick when squeezing the incense. When the motor rotates in reverse, it drives the screw to rotate via the passive gear, synchronous cylinder, positioning block, connecting cylinder, worm, and worm wheel, and adjusts the reference position of the movable frame via the adjusting plate and the adjusting plate. This allows the switching between the two working conditions of blocking the bamboo stick and adjusting the fixed length of the incense stick to be completed by switching the forward and reverse directions of a single motor. This avoids the need to set up a separate drive mechanism for adjusting the position of the baffle, so that the automatic adjustment of the length of the incense stick can be achieved without adding an independent power source. The whole machine has fewer parts and a simpler structure.

[0019] 2. By tilting the adjusting plate, ensuring its contact with the adjusting plate, and allowing the strip plate to slide only relative to the movable frame along the extension direction of the strip groove, the adjusting plate slides along the inclined surface of the adjusting plate when the movable frame slides back and forth, causing the strip plate to move relative to the movable frame. The baffle moves with the strip plate, so that the baffle not only moves with the movable frame relative to the machine housing, but also moves relative to the movable frame itself through the adjusting plate. This increases the amount of baffle movement when the movable frame retracts, providing more clearance for the incense sticks during dispensing, avoiding interference between the incense sticks and adjacent components during dispensing, and eliminating the need to increase the stroke of the movable frame. At the same time, even if the movable frame is dragged back and forth during the adjustment process, the position after the adjusting plate moves into place is the final position of the movable frame positioning reference. The back-and-forth movement of the movable frame does not affect the adjustment result, and the endpoint of the adjustment action is determined by the position of the adjusting plate.

[0020] 3. By having the positioning block engage with the slot in only one direction to drive the connecting cylinder to rotate, and disengage from the slot when rotating in the opposite direction, the engagement and disengagement of the rotational action between the driven gear and the connecting cylinder is realized. In the forward rotation condition, the connecting cylinder is not driven and the worm gear is stationary. In the reverse rotation condition, the connecting cylinder is driven to achieve adjustment. The direction selection is completely completed by the mechanical structure, avoiding the use of complex clutches or reversing components. The structure is simple and the operation is reliable.

[0021] 4. Through the magnetic attraction between the positioning section and the magnetic block, the positioning block automatically resets and re-inserts into the buckle groove after being squeezed by the buckle groove and rotates around the support column to avoid it. This ensures that the positioning block's unidirectional contact with the buckle groove continues to be effective in each rotation cycle without the need for manual intervention to reset.

[0022] 5. A spring is sleeved on the outer circumference of the slide rod, with its two ends abutting against the inner wall of the strip groove and the outer wall of the fixed cylinder, respectively. The elastic force of the spring keeps the adjusting plate always in contact with the adjusting plate. When the adjusting plate moves in the reverse direction, the strip plate follows synchronously through the spring, realizing bidirectional continuous adjustment of the baffle position. This avoids the gap caused by the adjusting plate disengaging from the adjusting plate when the adjusting plate moves in the reverse direction, which would result in a stroke gap during the next forward adjustment and cause the incense stick length adjustment to fail. The incense stick length can correspond to the adjusting plate position in both adjustment directions. Attached Figure Description

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 1-21 As shown, the present invention provides an integrated machine for making incense sticks and shaping, including a housing 1, a movable frame 4, a motor 105, a drive gear 5 and a driven gear 6. The housing 1 has a box-shaped structure, and the top of the housing 1 is the mounting position for the movable frame 4, the drive gear 5 and the driven gear 6. A skewer holder 102 is fixed on the side of the machine housing 1 facing the direction of bamboo skewer insertion. The skewer holder 102 has a through hole for the bamboo skewer to pass through. After the bamboo skewer is inserted into the skewer holder 102, its end extends to the incense squeezing station. A feeding hopper 2 is fixed on the top of the machine housing 1. The feeding hopper 2 is located above the skewer holder 102. A feeding pipe 103 is connected between the feeding hopper 2 and the skewer holder 102. The incense paste is transported to the skewer holder 102 through the feeding hopper 2 and the feeding pipe 103. A partition 104 is fixed on the side of the machine housing 1 away from the skewer holder 102. The partition 104 closes the opening on this side of the machine housing 1. A ventilation groove 104a is opened in the middle of the partition 104. The interior of the machine housing 1 is connected to the outside through the ventilation groove 104a.

[0028] Motor 105 is fixed to the inner wall of housing 1. The output shaft of motor 105 is connected to drive gear 5. Drive gear 5 is rotatably located at the top of housing 1 and meshes with driven gear 6. A rotating shaft 501 is located at an eccentric position at the top of drive gear 5. A connecting rod 502 is rotatably located in the middle of rotating shaft 501. A slider 503 is located at the end of connecting rod 502 away from rotating shaft 501. A slide rail 112 is located at the top of housing 1 and extends along the reciprocating sliding direction of movable frame 4. Sliding slider 503 is slidably located in slide rail 112. Movable frame 4 is fixed to the top of slider 503. When motor 105 rotates forward, drive gear 5 rotates with output shaft of motor 105. Rotating shaft 501 rotates eccentrically around axis of drive gear 5 and drives connecting rod 502 to swing. Connecting rod 502 drives slider 503 to reciprocate along slide rail 112. 4. As the slider 503 slides back and forth on the top of the housing 1, the middle section of the movable frame 4 bends downward toward the side wall of the housing 1. The bent frame is parallel to the side wall of the housing 1. An extension frame 101 is fixed to the outer wall of the housing 1 corresponding to the middle section of the movable frame 4. The extension frame 101 extends along the reciprocating direction of the movable frame 4. A support groove 401 is provided in the middle section of the movable frame 4. The support groove 401 slides in cooperation with the extension frame 101. When the movable frame 4 slides back and forth, the support groove 401 slides along the extension frame 101. The extension frame 101 supports the middle section of the movable frame 4, so that the movable frame 4 remains stable during the reciprocating sliding process. A connecting plate 405 is provided at the end of the movable frame 4. The connecting plate 405 is located at the end of the movable frame 4 facing the bamboo stick. A transverse groove 405a is provided in the middle of the connecting plate 405. The extension direction of the transverse groove 405a is parallel to the sliding direction of the slider 503.

[0029] A driven gear 6 is rotatably mounted on the top of the housing 1, meshing with the driving gear 5. A synchronizing cylinder 601 is coaxially mounted on the bottom of the driven gear 6, penetrating the top of the housing 1 and extending into its interior. A mounting groove 602 is formed on the outer wall of the synchronizing cylinder 601, extending axially along the cylinder and penetrating its wall. A support column 607 is vertically fixed to the inner end of the mounting groove 602, and a positioning block 603 is rotatably mounted on the support column 607. The positioning block 603 is located within the mounting groove 602 and extends through the wall of the synchronization cylinder 601 towards the inner side of the synchronization cylinder 601. The positioning block 603 is a triangular pyramidal block, with one side being an inclined surface 603a and the other side being a positioning surface 603b. A positioning section 603c is provided on one side of the positioning block 603, extending to the other side of the mounting groove 602. The positioning section 603c is made of metal. A magnetic block 602a is fixed within the mounting groove 602 near the positioning section 603c (see details). Figure 14 When the magnetic block 602a and the positioning section 603c are magnetically attracted, the magnetic block 602a will reset the positioning block 603 when the positioning block 603 rotates around the support column 607. A connecting cylinder 604 is coaxially sleeved inside the synchronous cylinder 601, with a rotational clearance between the connecting cylinder 604 and the synchronous cylinder 601. A limit plate 604a is fixed to the outer wall of the middle section of the connecting cylinder 604. A rotating frame 106 is fixed to the top of the housing 1 corresponding to the bottom of the driven gear 6. The limit plate 604a is rotatably connected to the middle of the rotating frame 106. The connecting cylinder 604 is supported by the rotating frame 106 via the limit plate 604a. The connecting cylinder 604 has a retaining groove 605, which extends axially along the connecting cylinder 604. A positioning block 603 extends into the retaining groove 605, with its end inserted into the retaining groove 605. When the driven gear 6 rotates, it drives the synchronous cylinder 601 to rotate in the same direction. When the driven gear 6 rotates in the direction corresponding to the forward rotation of the motor 105, the retaining groove 604a... The side wall of the positioning block 603 contacts the inclined surface 603a of the positioning block 603. The inclined surface 603a is squeezed by the side wall of the buckle groove 605. The positioning block 603 rotates around the support column 607 and disengages from the buckle groove 605. The connecting cylinder 604 is not driven. The rotation of the driven gear 6 is separated from the rotation of the connecting cylinder 604. When the driven gear 6 rotates in the direction corresponding to the reverse rotation of the motor 105, the side wall of the buckle groove 605 contacts the positioning surface 603b of the positioning block 603. The positioning surface 603b abuts against the side wall of the buckle groove 605. The positioning block 603 drives the connecting cylinder 604 to rotate synchronously. After the positioning block 603 disengages from the buckle groove 605, the magnetic block 602a and the positioning section 603c magnetically engage, driving the positioning block 603 to rotate back around the support column 607, so that the positioning block 603 re-inserts into the buckle groove 605.

[0030] A worm gear 606 is provided at the bottom of the connecting cylinder 604, and the worm gear 606 rotates synchronously with the connecting cylinder 604. A screw 109 is rotatably provided inside the housing 1, and the axis of the screw 109 is arranged perpendicularly to that of the worm gear 606. A worm wheel 109a is fixed to the end of the screw 109, and the worm wheel 109a meshes with the worm gear 606. A support plate 107 is fixed to the side wall of the housing 1 near the screw 109, and the end of the screw 109 is rotatably connected to the support plate 107. The screw 109 is supported by the support plate 107. Plate 107 is rotatably disposed inside housing 1. A fixing rod 109b is fixed on the side of worm gear 109a away from screw 109. The fixing rod 109b extends along the axis of worm gear 109a. The end of the fixing rod 109b is rotatably disposed on the inner wall of partition plate 104. The fixing rod 109b supports the side of screw 109 and worm gear 109a away from support plate 107. The two ends of screw 109 and worm gear 109a are respectively supported by support plate 107 and fixing rod 109b. The screw 109 is threadedly fitted with a guide plate 108, which is sleeved on the screw 109. A guide bracket 110 is fixed to the end of the support plate 107 facing the screw 109 (see details). Figure 11The guide frame 110 extends axially along the screw 109 and passes through the guide plate 108. The guide plate 108 is limited by the guide frame 110. When the screw 109 rotates, the guide plate 108 only moves axially along the screw 109 and does not rotate with the screw 109. An adjusting plate 108a is inclined on one side of the guide plate 108. The adjusting plate 108a is fixedly connected to the guide plate 108. The adjusting plate 108a extends inclinedly from the guide plate 108 towards the movable frame 4. When the connecting cylinder 604 rotates, it drives the worm 606 to rotate. The worm 606 drives the worm wheel 109a to rotate through meshing. The worm wheel 109a drives the screw 109 to rotate. When the screw 109 rotates, the guide plate 108 moves axially along the screw 109. The adjusting plate 108a moves axially along the screw 109 with the guide plate 108. When the motor 105 rotates forward, the connecting cylinder 604 is not driven, and the position of the adjusting plate 108a remains unchanged.

[0031] The strip plate 402 is slidably disposed at the bottom of the connecting plate 405. The strip plate 402 is slidable relative to the movable frame 4. A strip groove 402a is formed in the middle of the strip plate 402. The extension direction of the strip groove 402a is perpendicular to the extension direction of the transverse groove 405a. Multiple fixing cylinders 408 are provided through the overlapping part of the strip groove 402a and the transverse groove 405a. The fixing cylinders 408 are arranged at intervals along the extension direction of the transverse groove 405a. The bottom of the fixing cylinders 408 is provided with the same fixing plate 409, which connects the bottoms of the fixing cylinders 408 into one piece. The top of the fixing cylinders 408 is provided with a buckle plate 408a. The diameter of the buckle plate 408a is larger than the opening width of the transverse groove 405a and the strip groove 402a. The buckle plate 408a presses against the top of the connecting plate 405. The fixing cylinders 408 clamp the connecting plate 405 and the strip plate 402a through the buckle plate 408a and the fixing plate 409. 2. The fixed cylinder 408 passes through the overlapping part of the transverse groove 405a and the strip groove 402a. The transverse groove 405a limits the position of the fixed cylinder 408 along the extension direction of the strip groove 402a. The strip plate 402 slides relative to the fixed cylinder 408 through the strip groove 402a. The strip plate 402 can only slide relative to the movable frame 4 along the extension direction of the strip groove 402a. A sliding rod 406 is provided in the strip groove 402a along the extension direction of the strip groove 402a. The sliding rod 406 passes through the corresponding fixed cylinder 408. The sliding rod 406 passes through each fixed cylinder 408 along the extension direction of the strip groove 402a. A spring 407 is sleeved on the side of the sliding rod 406 away from the baffle 403. The spring 407 is sleeved on the outer periphery of the sliding rod 406. One end of the spring 407 abuts against the inner wall of the strip groove 402a away from the baffle 403, and the other end of the spring 407 abuts against the outer wall of the adjacent fixed cylinder 408. An adjusting plate 404 is provided at the top of the strip plate 402, extending upward from the strip plate 402 and fitting against the adjusting plate 108a. A baffle 403 is provided at the bottom of the strip plate 402, facing the skewer holder 102. The baffle 403 is used to block the movement of the bamboo skewer ends. When the motor 105 reverses, the adjusting plate 108a moves axially along the screw 109, pressing the adjusting plate 404. The adjusting plate 404 pushes the strip plate 402, causing the strip plate 402 to slide relative to the movable frame 4 along the extension direction of the strip groove 402a. The spring 407 is compressed, and the baffle 403 moves with the strip plate 402. As the baffle 403 moves, the distance between it and the end of the bamboo stick changes accordingly. When the adjusting plate 108a moves in the opposite direction, the spring 407 extends and pushes the strip plate 402 through the inner wall of the strip groove 402a. The strip plate 402 slides in the opposite direction with the adjusting plate 108a. The adjusting plate 404 always remains in contact with the adjusting plate 108a. The distance between the baffle 403 and the end of the bamboo stick changes in the opposite direction. When the motor 105 rotates in the forward direction, the position of the adjusting plate 108a remains unchanged. The strip plate 402 is held in place by the spring 407. The position of the baffle 403 moves with the reciprocating movement of the movable frame 4. The movable frame 4 drives the baffle 403 to press against the end of the bamboo stick when squeezing the incense.

[0032] The housing 1 has a through groove 111 facing the baffle 403 (see details). Figure 17 The through groove 111 extends laterally and penetrates the side wall of the housing 1. The adjusting plate 108a extends out of the housing 1 from inside the housing 1 through the through groove 111. The adjusting plate 108a extends through the through groove 111 to the movable frame 4. The adjusting plate 108a moves axially along the screw 109 within the through groove 111. A protective cover 3 is fixed on the outer wall of the top of the housing 1 corresponding to the driving gear 5 and the driven gear 6. The protective cover 3 covers the driving gear 5 and the driven gear 6 and shields the meshing parts of the driving gear 5 and the driven gear 6. A clearance groove 301 is provided on the protective cover 3 at the position corresponding to the connecting rod 502 (see details). Figure 4 The clearance groove 301 extends laterally, and the connecting rod 502 extends out of the cover 3 through the clearance groove 301. When the connecting rod 502 rotates eccentrically with the rotating shaft 501, it swings in the clearance groove 301. When the whole machine is running, the bamboo stick is inserted from the stick holder 102 and the end of the bamboo stick extends to the incense extrusion station. The motor 105 rotates forward, and the drive gear 5 rotates with the output shaft of the motor 105. The rotating shaft 501 rotates eccentrically around the axis of the drive gear 5. The connecting rod 502 drives the movable frame 4 to slide back and forth along the slide rail 112 via the slider 503. When the incense is extruded, the movable frame 4 abuts against the end of the bamboo stick through the baffle 403, and the axial position of the bamboo stick is locked. The incense paste is transported to the incense extrusion station through the feeding hopper 2 and the feeding pipe 103 and extruded into shape on the surface of the bamboo stick. After the incense is extruded, the movable frame 4 retracts, and the bamboo stick moves the formed incense stick out of the stick holder 102. When the incense stick length needs to be adjusted, motor 105 reverses, driving gear 5 to rotate passive gear 6 in the opposite direction. Synchronous cylinder 601 rotates in the opposite direction with passive gear 6. The side wall of buckle groove 605 contacts the positioning surface 603b of positioning block 603, and positioning surface 603b abuts against the side wall of buckle groove 605. Positioning block 603 drives connecting cylinder 604 to rotate, and connecting cylinder 604 drives worm gear 606 to rotate. Worm gear 606 drives screw 109 to rotate via worm wheel 109a. Guide plate 108 is limited by guide frame 110 and moves axially along screw 109. Adjusting plate 108a moves with guide plate 108. The motor 105 moves and presses the adjusting plate 404, which pushes the strip plate 402 to slide relative to the movable frame 4 along the extension direction of the strip groove 402a. The baffle 403 moves with the strip plate 402, and the distance between the baffle 403 and the end of the bamboo stick changes, thus changing the length of the incense stick. When the adjusting plate 108a moves in the opposite direction, the spring 407 extends and pushes the strip plate 402 to move with the adjusting plate 108a. The adjusting plate 404 remains in contact with the adjusting plate 108a, and the length of the incense stick is adjusted in the opposite direction. After the adjustment is completed, the motor 105 resumes forward rotation, the movable frame 4 slides back and forth again, and the incense squeezing process continues.

[0033] The processing method of the incense stick making and shaping integrated machine includes the following steps: a. Insert the bamboo skewer into the skewer-insertion station, so that the end of the bamboo skewer is located in the fragrance-extrusion station. The motor 105 rotates forward and drives the movable frame 4 to slide back and forth through the drive gear 5. When the fragrance is extruded, the movable frame 4 presses against the end of the bamboo skewer to lock the axial position of the bamboo skewer, and at the same time the fragrance is extruded and shaped. b. After the incense is extruded, the movable frame 4 retracts, and the bamboo stick moves the formed incense stick out. When it is necessary to adjust the length of the incense stick, the motor 105 reverses, and the active gear 5 drives the passive gear 6 to rotate in the opposite direction. The positioning block 603 abuts against the buckle groove 605 and drives the connecting cylinder 604 to rotate. The worm gear 606 and worm wheel 109a drive the screw 109 to rotate, so that the guide plate 108 moves along the axial direction of the screw 109. The adjusting plate 108a drives the strip plate 402 to slide relative to the movable frame 4 through the adjusting plate 404, thereby adjusting the positioning reference position of the movable frame 4 and adjusting the length of the incense stick. After the adjustment is completed, the motor 105 resumes forward rotation and the incense extrusion begins again. By using motor 105 as both the reciprocating drive source for movable frame 4 and the position adjustment drive source for baffle 403, when motor 105 rotates forward, it drives movable frame 4 to slide back and forth via eccentric transmission of active gear 5, and presses against the end of bamboo stick when squeezing incense. When motor 105 rotates in reverse, it drives screw 109 to rotate via passive gear 6, synchronous cylinder 601, positioning block 603, connecting cylinder 604, worm 606, and worm wheel 109a, and adjusts the reference position of movable frame 4 via adjusting plate 108a and adjusting plate 404. This achieves the switching between blocking bamboo stick and adjusting the fixed length of incense stick by switching the forward and reverse directions of a single motor 105, avoiding the need to set up a separate drive mechanism for adjusting the position of baffle 403. The automatic adjustment of incense stick length can be achieved without adding an independent power source. The whole machine has fewer parts and a simpler structure. With the adjusting plate 108a tilted, the adjusting plate 404 in contact with the adjusting plate 108a, and the strip plate 402 only able to slide relative to the movable frame 4 along the extension direction of the strip groove 402a, when the movable frame 4 reciprocates, the adjusting plate 404 slides along the inclined surface 603a of the adjusting plate 108a and drives the strip plate 402 to generate a follow-up displacement relative to the movable frame 4. The baffle 403 moves with the strip plate 402, so that the baffle 403 not only moves with the movable frame 4 relative to the housing 1, but also generates a displacement relative to the movable frame 4 through the adjusting plate 108a. The displacement increases the movement of the baffle 403 when the movable frame 4 retracts, providing more clearance for the incense stick during dispensing and preventing interference between the incense stick and adjacent parts. It also eliminates the need to increase the stroke of the movable frame 4. Furthermore, even if the movable frame 4 is dragged and reciprocated during adjustment, the position of the adjusting plate 108a after it has moved into place is the final position of the positioning reference of the movable frame 4. The reciprocating movement of the movable frame 4 does not affect the adjustment result, and the endpoint of the adjustment action is determined by the position of the adjusting plate 108a. By having the positioning block 603 abut against the latching groove 605 in only one direction to drive the connecting cylinder 604 to rotate, and disengaging from the latching groove 605 when rotating in the opposite direction, the engagement and disengagement of the rotational action between the driven gear 6 and the connecting cylinder 604 is realized. In the forward rotation condition, the connecting cylinder 604 is not driven and the worm 606 and worm wheel 109a are stationary. In the reverse rotation condition, the connecting cylinder 604 is driven to achieve adjustment. The direction selection is completely completed by the mechanical structure, avoiding the use of complex clutches or reversing components. The structure is simple and the operation is reliable. By magnetically engaging the positioning segment 603c with the magnetic block 602a, the positioning block 603 automatically resets and re-inserts into the locking groove 605 after being squeezed by the locking groove 605 and rotating around the support column 607 to avoid it. This ensures that the positioning block 603 continues to effectively abut against the locking groove 605 in each rotation cycle without the need for manual intervention to reset. Spring 407 is sleeved on the outer periphery of slide rod 406, with its two ends abutting against the inner wall of strip groove 402a and the outer wall of fixed cylinder 408 respectively. The elastic force of spring 407 keeps adjusting plate 404 always in contact with adjusting plate 108a. When adjusting plate 108a moves in the reverse direction, strip plate 402 follows synchronously via spring 407, realizing bidirectional continuous adjustment of the position of baffle 403. This avoids gaps caused by adjusting plate 404 and adjusting plate 108a disengaging when adjusting plate 108a moves in the reverse direction, which would lead to stroke idleness during the next forward adjustment and cause the incense stick length adjustment to fail. The incense stick length can correspond to the position of adjusting plate 108a in both adjustment directions.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
