Description

Technical Field

[0001] This invention relates to the technical field of feeding devices, specifically a feeding device for a dryer used for chemical fiber paper tubes. Background Technology

[0002] Chemical fiber paper tubes are paper tubes used for winding chemical fibers, spinning, or texturing. In the chemical fiber production process, paper tubes serve as carriers for chemical fiber filaments and play a crucial role in various stages of chemical fiber application conversion and deep processing. Before the drying process, chemical fiber paper tubes need to pass through a feeding device, which transports the chemical fiber paper tubes processed in the previous process to the dryer.

[0003] Patent document CN113968449B discloses an automatic paper tube feeding device, belonging to the field of operational technology. It solves the problems of high labor intensity, low efficiency, and high error rate in existing paper tube detection and sorting. This automatic paper tube feeding device includes a frame and a paper tube positioning seat installed on the frame. A chain conveying assembly is provided on the horizontal side of the paper tube positioning seat. Multiple conveying grooves are arranged on the chain conveying assembly. The operation of the chain conveying assembly enables each paper tube in the conveying groove to be in a relative state with the paper tube positioning seat. A pushing assembly is also installed on the frame. The pushing assembly can push the paper tube in the relative state with the paper tube positioning seat to move axially and make the paper tube fit on the paper tube positioning seat. This automatic paper tube feeding device not only improves the consistency of the state of the paper tubes fitted on the paper tube positioning seat, but also improves the subsequent inspection pass rate and significantly reduces the amount of paper tube damage during the pushing process.

[0004] However, in actual use, the inventors found that paper tubes are usually piled up in a disorderly and scattered state in the feeding area. This disordered state makes it easy for the paper tubes to generate friction during the conveying process, which in turn leads to the presence of foreign objects (such as fragments, paper scraps, etc.) inside and outside the paper tubes. These foreign objects will pass through the feeding device with the paper tubes and be sent into the interior of the subsequent dryer. In addition, chemical fiber paper tubes are prone to static electricity during high-speed conveying, especially when using plastic conveying slides or air conveying methods. This will also cause the paper tubes to attract dust, affecting the forming quality of subsequent paper tube bonding. Summary of the Invention

[0054] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0055] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0056] like Figures 1-2 As shown, a feeding device for a dryer of chemical fiber paper tubes includes:

[0057] The paper tube conveying mechanism 1, the paper tube body 100 moves sequentially along the upper feeding assembly 11, the middle feeding assembly 12 and the lower feeding assembly 13 on the paper tube conveying mechanism 1;

[0058] The lower end of the lower feeding assembly 13 is provided with an intermittent feeding mechanism 2, which includes an end feeding unit 21 disposed at the discharge end of the lower feeding assembly 13 and several sets of intermittent feeding units 22 connected to the end feeding unit 21 and disposed at the lower end of the lower feeding assembly 13. The end feeding unit 21 drives several sets of intermittent feeding units 22 to work synchronously, thereby driving multiple sets of paper tube bodies 100 to move intermittently.

[0059] An internal cleaning mechanism 3 is disposed on one side of the lower feeding assembly 13. The internal cleaning mechanism 3 is used to clean the inner wall of one of the paper tube bodies 100 on the lower feeding assembly 13.

[0060] External cleaning mechanism 4 is disposed at the upper end of the lower feeding assembly 13 and is used to clean the outer surface of the paper tube body 100 disposed on the lower feeding assembly 13;

[0061] An ion air bar 5 is also provided at the upper end of the lower feeding assembly 13, and the ion air bar 5 is located at the front end of the external cleaning mechanism 4.

[0062] The paper tube rolls along the inclined conveyor assembly under the action of gravity, passing through the upper, middle and lower feeding sections in sequence. When it reaches the lower feeding section, the intermittent feeding mechanism 2 controls the paper tube to move in batches. When the paper tube stops, the cleaning head 31 of the inner cleaning mechanism 3 extends into the tube body to rotate and clean. At the same time, the airflow and brush of the outer cleaning mechanism 4 remove impurities from the outer surface. The ion air bar 5 eliminates static electricity on the surface of the paper tube before cleaning to avoid dust adsorption during the cleaning process. All components work together to ensure that each paper tube completes internal and external cleaning and static electricity treatment during the conveying process.

[0063] Furthermore, such as Figures 1-5 As shown, the upper feeding assembly 11, the middle feeding assembly 12 and the lower feeding assembly 13 are all inclined. Under the action of gravity, the paper tube body 100 rolls downward along the upper feeding assembly 11, the middle feeding assembly 12 and the lower feeding assembly 13 in sequence.

[0064] The lower feeding assembly 13 includes a base plate 132 disposed on a support base 131 and side plates 133 disposed on both sides of the base plate 132.

[0065] The paper tube body 100 automatically rolls downwards along the inclined feeding assembly under the action of gravity, without the need for external power. The continuous inclined structure of the upper feeding assembly 11, the middle feeding assembly 12, and the lower feeding assembly 13 forms a stepped conveying path, allowing the paper tube to naturally disperse and arrange itself during the rolling process. The rigid support surface of the base plate 132 can prevent the paper tube from deviating from its movement trajectory due to local depressions or deformations. The guide channel formed by the two side plates 133 is slightly wider than the length of the paper tube, allowing the paper tube to roll freely while preventing it from sliding laterally out of the conveying path.

[0066] This application achieves orderly arrangement and directional movement of paper tubes during the conveying process, effectively reducing surface scratches and foreign matter residue caused by disordered stacking. The continuous support surface of the base plate 132 avoids local friction between the paper tubes and the conveying device, while the guiding function of the side plate 133 prevents collisions or jamming caused by lateral displacement of the paper tubes. The gravity-driven mechanism of the inclined structure not only simplifies the device structure but also reduces conveying instability caused by mechanical power fluctuations.

[0067] Furthermore, such as Figures 2-5 As shown, the base plate 132 has at least one set of placement slots 1321 at the position corresponding to the intermittent feeding mechanism 2;

[0068] The end feeding unit 21 includes a first rotating shaft 211, a vertical baffle 212 fixedly mounted on the first rotating shaft 211 and integrally formed, and an arc baffle 213.

[0069] The intermittent feeding unit 22 includes a second rotating shaft 221, a limiting baffle 222 fixedly mounted on the second rotating shaft 221, and a rotating wheel 223 mounted on one side of the second rotating shaft 221.

[0070] As the paper tube rolls downward along the lower feeding assembly 13, the first rotating shaft 211 of the end feeding unit 21 drives the vertical baffle 212 and the arc-shaped baffle 213 to rotate synchronously. When the vertical baffle 212 rotates to a near-vertical position, it blocks the movement of the paper tube. When the first rotating shaft 211 continues to rotate, the vertical baffle 212 moves out of the blocking position, and the arc-shaped baffle 213 blocks the paper tube behind it. The paper tube body 100 moves out of the intermittent feeding mechanism 2 along the inclined vertical baffle 212, and at this time, the curved surface of the arc-shaped baffle 213 blocks the paper tube body 100 behind it, thereby ensuring that only one paper tube body 100 completes the discharge at a time.

[0071] Meanwhile, the second rotating shaft 221 of the intermittent feeding unit 22 receives a drive signal through the rotating wheel 223, causing the limiting baffle 222 to rotate periodically. When the limiting baffle 222 is in a horizontal position, the paper tube is released and moves downward one station; when the limiting baffle 222 rotates to an inclined angle, it prevents the paper tube from continuing to roll. The placement slot 1321 ensures that the installation position of each intermittent feeding unit 22 is precisely matched with the action of the end feeding unit 21, avoiding lateral displacement or collision of the paper tube during intermittent movement due to positional deviation.

[0072] Through the above technical solution, this application achieves precise positioning and attitude control during the intermittent conveying of paper tubes, reducing frictional damage caused by structural misalignment or asynchronous movements, and effectively preventing foreign objects from falling off the inner wall of the paper tube and dust from adsorbing on the outer surface. Multiple intermittent feeding units 22 maintain synchronous operation under the positioning of the placement trough 1321 and belt drive, avoiding compression deformation caused by paper tube accumulation and ensuring that the cleanliness of the paper tubes inside and outside meets process requirements before drying.

[0073] It should be noted that in this embodiment, the placement slot 1321 is provided in two sets. Therefore, there are two sets of vertical baffles 212 and arc-shaped baffles 213, and two sets of limiting baffles 222 on the same second rotating shaft 221 are also provided.

[0074] Furthermore, such as Figure 6 As shown, several sets of rotating wheels 223 are connected by a transmission belt 224, and the transmission belt 224 is connected to the first rotating shaft 211.

[0075] A drive belt 224 is mounted around the outer circumference of each rotating wheel 223. When the first rotating shaft 211 is driven to rotate, the drive belt 224 drives all rotating wheels 223 to rotate at the same angular velocity. Since the rotating wheels 223 and the limiting baffles 222 are fixed on the same second rotating shaft 221, the synchronous rotation of the rotating wheels 223 causes the limiting baffles 222 of each intermittent feeding unit 22 to move synchronously, thereby ensuring that the paper tube is simultaneously pushed or blocked by multiple sets of limiting baffles 222 during the conveying process. By driving the drive belt 224 with a single power source, the timing deviation caused by multiple power sources is avoided. At the same time, the elasticity of the drive belt 224 can absorb the instantaneous impact during rotation and reduce mechanical wear.

[0076] Through the above technical solution, this application solves the problem of paper tube jamming or accumulation caused by asynchronous power in multiple intermittent feeding units 22, ensuring that the paper tube maintains a continuous and uniform intermittent movement rhythm during the conveying process. The linkage design between the transmission belt 224 and the rotating wheel 223 further reduces the impact loss of mechanical parts caused by rigid connection, extends the service life of the equipment, and reduces scratch damage to the paper tube surface caused by synchronization error.

[0077] Furthermore, such as Figures 7-9 As shown, the internal cleaning mechanism 3 includes a cleaning head 31, a connecting rod 32, and an air blowing pipe 33. The side plate 133 has a through hole 1331 at the position corresponding to the cleaning head 31. The connecting rod 32 is fixedly connected to the cleaning head 31. The air blowing pipe 33 is disposed inside the connecting rod 32 and the cleaning head 31 through a rotating component (which can be a bearing), and one end of the air blowing pipe 33 extends out of the cleaning head 31.

[0078] When the paper tube moves to the corresponding position of the inner cleaning mechanism 3, the cleaning head 31 extends into the inner cavity of the paper tube through the through hole 1331 of the side plate 133, and its outer wall fits tightly against the inner wall of the paper tube. The connecting rod 32 fixes the position of the cleaning head 31 to prevent it from shifting during the cleaning process. The air blowing pipe 33 rotates inside the connecting rod 32 through the rotating component, continuously releasing airflow from one end of the cleaning head 31. The airflow direction changes continuously with the rotation of the air blowing pipe 33, forming a multi-angle scouring of the inner wall of the paper tube. While maintaining the rotation of the air blowing pipe 33, the rotating component prevents the airflow channel from being blocked or damaged due to friction.

[0079] Through the above technical solution, this application solves the problem of reduced processing quality caused by foreign matter residue on the inner wall of the paper tube. The cooperation between the cleaning head 31 and the air blowing pipe 33 can effectively peel off and remove paper scraps, dust and other impurities attached to the inner wall during the continuous conveying of the paper tube through the dual action of mechanical contact and airflow scouring, thus preventing foreign matter from entering the dryer and affecting the forming quality of chemical fiber filaments.

[0080] Furthermore, such as Figure 9 As shown, the outer wall of the cleaning head 31 is fitted to the inner wall of the paper tube body 100, and the cleaning head 31 has an inwardly recessed groove 311 on the side facing the paper tube body 100.

[0081] As the paper tube moves to the cleaning station, the cleaning head 31 is pushed into the tube. The outer wall of the elastic rubber cleaning head 31 deforms under pressure, forming a surface contact with the inner wall of the paper tube, eliminating the gap between traditional rigid cleaning tools and the tube wall. During the rotation of the cleaning head 31, the edge of the U-shaped groove 311 on its surface continuously rubs against the inner wall of the paper tube, scraping away adhering substances. Simultaneously, the airflow vortex formed inside the groove 311 can suck in and temporarily store the detached debris, preventing it from scattering back onto the inner wall of the paper tube during cleaning. Compressed air output from the air pipe 33 acts evenly on the tube wall through the diffusion channel formed by the groove 311, further enhancing the blowing effect.

[0082] Through the above technical solution, this application achieves efficient removal of foreign objects from the inner wall of the paper tube, avoiding secondary pollution caused by debris rebound during the cleaning process. The local negative pressure area formed by the groove 311 structure enhances the debris collection capacity, and the elastic fit design ensures that the cleaning head 31 can fully contact paper tubes of different sizes, significantly improving the stability and reliability of the cleaning operation.

[0083] Furthermore, such as Figure 8 As shown, a waste collection bin 6 is provided on the side of the lower feeding assembly 13 away from the inner cleaning mechanism 3.

[0084] After the paper tube passes through the internal cleaning mechanism 3 and its inner wall is cleaned, any debris or dust adhering to its outer surface will naturally fall off during subsequent conveying. The waste collection bin 6 is positioned on the side of the lower feeding assembly 13 away from the cleaning area through a spatial isolation design, allowing the detached waste to fall directly into the bin. The paper tube does not need to stop or adjust its position during conveying, and the waste is collected centrally through a directional collection method, preventing it from scattering into the conveying path or inside the equipment.

[0085] Furthermore, such as Figures 1-2 As shown, the air blowing pipe 33 and the external cleaning mechanism 4 are both connected to the blower unit 7;

[0086] The external cleaning mechanism 4 includes an air blowing unit 41 disposed on the upper end of the lower feeding assembly 13 and a cleaning unit 42 disposed on one side of the air blowing unit 41 and overlapping with the upper surface of the paper tube body 100.

[0087] As the paper tube body 100 moves along the lower feeding assembly 13 to the outer cleaning area, the air blowing unit 41 first performs a preliminary cleaning of the outer surface of the paper tube using compressed air supplied by the blower unit 7, blowing away loosely attached paper scraps and dust particles. The paper tube then continues to move below the cleaning unit 42, which continuously contacts the upper surface of the paper tube and applies moderate pressure, using the friction of brush bristles or a scraper to remove fine dust remaining due to electrostatic adsorption. Dust generated during the blowing and cleaning process is blocked by dust baffles, preventing it from re-adhering to the cleaned paper tube surface. The blower unit 7 supplies air to the air blowing pipe 33 and the air blowing unit 41 through independent air paths, and can adjust the air pressure parameters of each air path according to cleaning needs to ensure optimal airflow intensity matching for both internal and external cleaning operations.

[0088] Through the above technical solution, this application can simultaneously remove loose deposits and electrostatically adsorbed dust from the outer surface of the paper tube, effectively preventing secondary contamination of the cleaned paper tube by dust during the cleaning process, and ensuring that the cleanliness of the inner and outer surfaces of the paper tube meets the strict requirements of the drying process for the amount of foreign matter residue. This solution, by coordinating pneumatic cleaning and mechanical sweeping, optimizes airflow utilization efficiency while ensuring cleaning effectiveness, solving the problems of incomplete dust removal and excessive energy consumption inherent in traditional single-method cleaning.

[0089] It should be noted that, optionally, a dustproof baffle is provided at the upper end of the paper tube body 100 at the rear end of the external cleaning mechanism 4. The dustproof baffle can protect this part of the paper tube body 100 from dust. In conjunction with the cleaning unit 42, it can effectively prevent the dust blown up by the external cleaning mechanism 4 from falling back onto the paper tube body 100 that is about to leave the paper tube conveying mechanism 1.

[0090] Furthermore, such as Figure 1 , Figures 10-11 As shown, a drive mechanism 8 is also provided on one side of the lower feeding assembly 13. The drive mechanism 8 includes a drive unit 82, which is fixedly mounted on the support platform 81. The drive gear 83 is driven by the drive unit 82 and is driven by the driven gear 84. The driven gear 84 is driven by the connecting rod 32 through a bushing 85, and the connecting rod 32 is threadedly connected to the bushing 85. The support rod 86 is fixedly mounted on the support platform 81, and the connecting rod 32 passes through the support rod 86.

[0091] After the drive unit 82 starts, it drives the drive gear 83 to rotate. The drive gear 83 meshes with the driven gear 84, causing the bushing 85 to rotate synchronously. Since the connecting rod 32 and the bushing 85 are connected by a thread, the rotation of the bushing 85 forces the connecting rod 32 to move linearly along the axial direction. The support rod 86 constrains the movement trajectory of the connecting rod 32 to prevent motion errors caused by radial offset. Thus, the connecting rod 32 drives the cleaning head 31 of the inner cleaning mechanism 3 to accurately insert into the inner cavity of the paper tube and complete the inner wall cleaning action in linear reciprocating motion. The threaded transmission structure controls the movement distance through the lead to ensure the fit between the cleaning head 31 and the inner wall of the paper tube; the gear meshing transmission ensures the synchronicity of power transmission and avoids positional deviations caused by transmission backlash.

[0092] Through the above technical solution, this application achieves high-precision linear drive of the internal cleaning mechanism 3, ensuring stable contact between the cleaning head 31 and the inner wall of the paper tube, and effectively removing attached foreign matter; the rigid connection of gear and thread transmission avoids energy loss during power transmission, and ensures that the cleaning action is strictly synchronized with the conveying rhythm, preventing cleaning omissions caused by timing misalignment.

[0093] Furthermore, such as Figures 10-12As shown, the driving mechanism 8 drives the intermittent feeding mechanism 2 through the transmission mechanism 9. The transmission mechanism 9 includes a support disk 91, which is rotatably connected to one end of the connecting rod 32. The moving rod 92 is fixedly disposed at the lower end of the support disk 91 and slidably disposed on the support platform 81. A toothed condition 93 is fixedly connected to the outer side of the moving rod 92. Two sets of rack units 931 are disposed on the rack unit 93, which are rotatably connected to the transmission gear 94 disposed on the support platform 81. The driving bevel gear 95 is coaxially disposed with the transmission gear 94 and is rotatably connected to the driven bevel gear 96. The driven bevel gear 96 is fixedly connected to the first rotating shaft 211, and one end of the first rotating shaft 211 is rotatably connected to the support rod 86.

[0094] When the drive mechanism 8 drives the connecting rod 32 to rotate, the support plate 91 converts the rotational motion into linear sliding of the moving rod 92, causing the gear condition 93 to move along the support platform 81. The two sets of rack units 931 on the gear condition 93 mesh with the transmission gears 94 on both sides, causing the transmission gears 94 to rotate synchronously. The transmission gears 94 drive the coaxial active bevel gear 95 to rotate. After the active bevel gear 95 meshes with the driven bevel gear 96, it transmits power to the first rotating shaft 211, driving the vertical baffle 212 and the arc baffle 213 of the end feeding unit 21 to move.

[0095] When the gear condition 93 moves to the point where the two sets of rack units 931 are completely disengaged from the transmission gear 94, the first rotating shaft 211 stops rotating. At this time, the vertical baffle 212 repositions the paper tube body 100, and the cleaning head 31 has completely exited the paper tube. The arc-shaped baffle 213 disengages from the preceding paper tube. This process ensures that the entry and exit of the cleaning head 31 and the release and blocking actions of the paper tube are strictly synchronized through the stroke coordination of the rack and gear.

[0096] Through the above technical solution, this application realizes the mechanical linkage control between the drive mechanism 8 and the intermittent feeding mechanism 2, ensuring that the paper tube immediately enters the conveying state after the inner wall cleaning is completed, avoiding the risk of interference between the cleaning head 31 and the moving paper tube. At the same time, the bevel gear transmission structure precisely adjusts the power transmission direction, so that the first rotating shaft 211 and the support rod 86 form a stable rotating connection.
