Description

Technical Field

[0001] The present invention relates to the technical field related to feeding devices, and in particular to a feeding device for a dryer of chemical fiber paper tubes. Background Art

[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 of chemical fiber filaments. They play a vital role in all aspects of the conversion of chemical fiber uses and deep processing of chemical fiber filaments. Before the drying process, chemical fiber paper tubes need to pass through a loading device, which transports the chemical fiber paper tubes processed in the previous process to the dryer.

[0003] The patent document with patent number CN113968449B discloses an automatic paper tube feeding device, which belongs to the field of operation technology. It solves the problems of high labor intensity, low efficiency and high error rate in existing paper tube detection and sorting. The 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. A plurality of conveying troughs are arranged on the chain conveying assembly. The operation of the chain conveying assembly can make each paper tube located in the conveying trough relative to the paper tube positioning seat; a pushing assembly is also installed on the frame. The pushing assembly can push the paper tube in a relative state with the paper tube positioning seat to move axially and make the paper tube be sleeved on the paper tube positioning seat. The automatic paper tube feeding device not only improves the consistency of the state of the paper tube sleeved on the paper tube positioning seat, but also improves the subsequent detection pass rate, and significantly reduces the amount of damage to the paper tube during the pushing process.

[0004] However, during actual use, the inventors found that paper tubes are usually stacked in the feeding area in a disordered and scattered state. This disordered state causes the paper tubes to easily generate friction during transportation, which in turn causes foreign matter (such as fragments, paper scraps, etc.) to be mixed inside and outside the paper tubes. These foreign matter will pass through the feeding device together with the paper tubes and be fed into the subsequent dryer. In addition, chemical fiber paper tubes are prone to static electricity during high-speed transportation, especially when using plastic conveying slides or air flow conveying methods, which will also cause the paper tubes to absorb dust, affecting the molding quality of subsequent sticky paper tubes.

[0030] The technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. The components of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for which protection is claimed, but merely represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0031] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0032] like Figure 1-Figure 2 As shown, a feeding device for a dryer of chemical fiber paper tubes comprises: The paper tube conveying mechanism 1 and the paper tube body 100 move in sequence along the upper feeding assembly 11, the middle feeding assembly 12 and the lower feeding assembly 13 on the paper tube conveying mechanism 1; The lower end of the lower feeding assembly 13 is provided with an intermittent feeding mechanism 2, which includes an end feeding unit 21 provided at the discharge end of the lower feeding assembly 13 and several groups of intermittent feeding units 22 connected to the end feeding unit 21 and provided at the lower end of the lower feeding assembly 13. The end feeding unit 21 drives several groups of the intermittent feeding units 22 to work synchronously and thus drives multiple groups of paper tube bodies 100 to move intermittently; An inner cleaning mechanism 3 is provided on one side of the lower feeding assembly 13 and is used to clean the inner wall of one of the paper tube bodies 100 on the lower feeding assembly 13; The external cleaning mechanism 4 is provided at the upper end of the lower feeding assembly 13 and is used to clean the outer surface of the paper tube body 100 provided on the lower feeding assembly 13; An ion wind rod 5 is further provided at the upper end of the lower feeding assembly 13 , and the ion wind rod 5 is provided at the front end of the external cleaning mechanism 4 .

[0033] Under the action of gravity, the paper tube rolls along the inclined conveying assembly, passing through the upper, middle and lower feeding sections in turn. 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 internal cleaning mechanism 3 extends into the tube body and rotates for cleaning. At the same time, the airflow and brush of the external cleaning mechanism 4 remove impurities on the outer surface. The ion wind rod 5 eliminates static electricity on the surface of the paper tube before cleaning to avoid dust adsorption during the cleaning process. The various components work together to ensure that each paper tube completes internal and external cleaning and static treatment during transportation.

[0034] Further, if Figure 1-Figure 5 As shown, the upper feeding assembly 11, the middle feeding assembly 12 and the lower feeding assembly 13 are all arranged tilted. 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. The lower feeding assembly 13 includes a bottom plate 132 disposed on a support base 131 and side plates 133 disposed on both sides of the bottom plate 132 .

[0035] The paper tube body 100 automatically rolls downward along the inclined feed assembly under the influence of gravity, requiring no external power. The continuously inclined structure of the upper feed assembly 11, the middle feed assembly 12, and the lower feed assembly 13 creates a stepped conveying path, naturally distributing the paper tubes during rolling. The rigid support surface of the bottom plate 132 prevents the paper tubes from shifting their trajectory due to localized dents or deformation. The guide channel formed by the side plates 133 is slightly wider than the diameter of the paper tube, allowing the paper tube to roll freely while preventing it from sliding laterally out of the conveying path.

[0036] This application achieves orderly arrangement and directional movement of paper tubes during transport, effectively reducing surface scratches and foreign matter residue caused by disordered stacking. The continuous support surface of the bottom plate 132 prevents localized friction between the paper tubes and the conveyor mechanism, while the guiding action of the side plates 133 prevents collisions or jams caused by lateral deviation of the paper tubes. The gravity-driven mechanism of the tilted structure not only simplifies the device structure but also reduces transport instability caused by mechanical power fluctuations.

[0037] Further, if Figure 2-Figure 5 As shown, the bottom plate 132 is provided with at least one set of placement slots 1321 at a position corresponding to the intermittent feeding mechanism 2; The end feeding unit 21 includes a first rotating shaft 211, a vertical baffle 212 fixedly disposed on the first rotating shaft 211 and integrally formed, and a curved baffle 213; The intermittent feeding unit 22 includes a second rotating shaft 221 , a limiting baffle 222 fixedly disposed on the second rotating shaft 221 , and a rotating wheel 223 disposed on one side of the second rotating shaft 221 .

[0038] 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 curved baffle 213 to rotate synchronously. When the vertical baffle 212 rotates to a nearly vertical position, it blocks the movement of the paper tube. When the first rotating shaft 211 continues to rotate, the vertical baffle 212 disengages from the blocking position, and the curved baffle 213 pushes the paper tube into the intermittent feeding unit 22 area. 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 curved baffle 213 blocks the paper tube body 100 behind it, thereby ensuring that only one paper tube body 100 is discharged at a time. Simultaneously, the second rotating shaft 221 of the intermittent feed unit 22 receives a drive signal via the rotating wheel 223, driving the stopper 222 to rotate periodically. When the stopper 222 is horizontal, the paper tube is released to move downward one station. When the stopper 222 is rotated to an inclined angle, it prevents the paper tube from rolling further. The placement slots 1321 ensure that the installation position of each intermittent feed unit 22 precisely matches the movement of the terminal feed unit 21, preventing lateral deviation or collision of the paper tube during intermittent movement due to positional deviation.

[0039] Through the above-described technical solution, the present application achieves precise positioning and posture control during intermittent paper tube conveying, reducing friction damage caused by structural misalignment or asynchronous movement, and effectively preventing foreign matter from falling off the inner wall of the paper tube and dust from absorbing onto the outer surface. Multiple intermittent feeding units 22, positioned in placement slots 1321 and driven by belts, maintain synchronized movement, avoiding compression deformation caused by paper tube accumulation and ensuring that the internal and external cleanliness of the paper tubes meets process requirements before drying.

[0040] It should be noted that, in this embodiment, two groups of placement slots 1321 are provided. Therefore, two groups of vertical baffles 212 and arc-shaped baffles 213 are provided. Two groups of limiting baffles 222 on the same second rotating shaft 221 are also provided.

[0041] Further, if Figure 6 As shown, the plurality of rotating wheels 223 are connected to each other via a transmission belt 224 , and the transmission belt 224 is connected to the first rotating shaft 211 .

[0042] A transmission belt 224 is mounted around the outer circumference of each rotating wheel 223. When the first rotating shaft 211 is driven to rotate, the transmission belt 224 drives all rotating wheels 223 to rotate at the same angular velocity. Because the rotating wheels 223 and the stop baffles 222 are fixed to the same second rotating shaft 221, the synchronous rotation of the rotating wheels 223 causes the stop baffles 222 of each intermittent feeding unit 22 to operate synchronously, ensuring that the paper tube is pushed or blocked simultaneously by multiple sets of stop baffles 222 during transportation. Using a single power source to drive the transmission belt 224 avoids timing deviations caused by multiple power sources. The elastic properties of the transmission belt 224 also absorb transient shocks during rotation, reducing mechanical wear.

[0043] Through the above-mentioned technical solution, the present application solves the problem of paper tube jamming or accumulation caused by power asynchrony in multiple intermittent feeding units 22, ensuring a continuous and uniform intermittent movement rhythm during paper tube transportation. The linkage design between the drive belt 224 and the rotating wheel 223 further reduces the impact loss caused by the rigid connection of mechanical components, extending the service life of the equipment and reducing scratches on the paper tube surface caused by synchronization errors.

[0044] Further, if Figure 7-Figure 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 panel 133 is provided with a through hole 1331 at a 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 arranged inside the connecting rod 32 and the cleaning head 31 through a rotating part (which can be a bearing), and one end of the air blowing pipe 33 extends out of the cleaning head 31.

[0045] When the paper tube moves to the corresponding position of the internal cleaning mechanism 3, the cleaning head 31 extends into the paper tube through the through-hole 1331 of the side panel 133, with its outer wall tightly fitting against the inner wall of the paper tube. A connecting rod 32 secures the cleaning head 31 in place, preventing it from shifting during the cleaning process. The air blower 33 rotates within the connecting rod 32 via a rotating member. The end extending from the cleaning head 31 continuously releases air, with the airflow direction changing as the air blower 33 rotates, providing a multi-angle cleansing effect on the inner wall of the paper tube. The rotating member maintains the rotation of the air blower 33 while preventing the air flow path from becoming clogged or damaged due to friction.

[0046] Through the above-mentioned technical solution, this application solves the problem of residual foreign matter on the inner wall of paper tubes, which can lead to reduced subsequent processing quality. The cleaning head 31 and the air blower 33 work together to effectively remove and remove impurities such as paper scraps and dust from the inner wall during the continuous conveying of paper tubes through the dual effects of mechanical contact and air flow, thus preventing foreign matter from entering the dryer and affecting the quality of chemical fiber formation.

[0047] Further, if Figure 9 As shown, the outer wall of the cleaning head 31 is fitted with the inner wall of the paper tube body 100 , and the cleaning head 31 is provided with an inwardly recessed groove 311 on a side facing the paper tube body 100 .

[0048] When the paper tube moves to the cleaning station, the cleaning head 31 is pushed into the paper tube. The outer wall of the elastic rubber cleaning head 31 is compressed and deformed, forming surface contact with the inner wall of the paper tube, eliminating the gap between traditional rigid cleaning tools and the tube wall. As the cleaning head 31 rotates, the edge of the U-shaped groove 311 on its surface continuously rubs against the inner wall of the paper tube, scraping off debris. Simultaneously, the air vortex formed within the groove 311 temporarily absorbs and stores the peeled debris, preventing it from scattering back onto the inner wall of the paper tube during the cleaning process. The compressed air output from the air blow pipe 33 acts evenly on the tube wall through the diffusion channel formed by the groove 311, further enhancing the purging effect.

[0049] Through the above technical solution, this application achieves efficient removal of foreign matter from the inner wall of the paper tube, avoiding secondary contamination caused by debris rebound during the cleaning process. The localized negative pressure area formed by the groove 311 structure enhances debris collection capacity, and the elastic fit design ensures that the cleaning head 31 fully contacts paper tubes of different sizes, significantly improving the stability and reliability of the cleaning operation.

[0050] Further, if Figure 8 As shown, a waste collection bucket 6 is provided on the side of the lower feeding assembly 13 away from the inner cleaning mechanism 3 .

[0051] After the paper tube passes through the internal cleaning mechanism 3 and its inner wall is cleaned, debris and dust adhering to the outer surface naturally fall off during subsequent transportation. The waste collection bucket 6 is spatially isolated and positioned on the side of the lower feed assembly 13, away from the cleaning area, allowing the fallen waste to fall directly into the bucket. The paper tube does not need to stop or adjust its position during transportation. Waste is collected and stored in a targeted manner, preventing it from scattering along the conveyor path or inside the equipment.

[0052] Further, if Figure 1-Figure 2 As shown, the air blowing pipe 33 and the external cleaning mechanism 4 are both connected to the fan unit 7; The external cleaning mechanism 4 includes an air blowing unit 41 disposed at 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 the upper surface of the paper tube body 100 .

[0053] When the paper tube body 100 moves along the lower feeding assembly 13 to the outer cleaning area, the blowing unit 41 first performs a preliminary purge on the outer surface of the paper tube through the compressed air supplied by the fan unit 7, blowing loosely attached paper scraps and dust particles off the surface. The paper tube then continues to move below the cleaning unit 42. The cleaning unit 42 maintains contact with the upper surface of the paper tube and applies moderate pressure, using the friction of the bristles or scraper to remove fine dust remaining due to electrostatic adsorption. The dust generated during the blowing and cleaning process is blocked by the dust baffle to prevent it from re-attaching to the surface of the cleaned paper tube. The fan unit 7 supplies air to the blowing pipe 33 and the blowing unit 41 through independent air paths. The air pressure parameters of each air path can be adjusted according to the cleaning needs to ensure that the airflow intensity of the internal and external cleaning operations is optimally matched.

[0054] Through the above-mentioned technical solution, this application can simultaneously remove loose attachments and electrostatically adsorbed dust from the outer surface of paper tubes, effectively preventing secondary contamination of the cleaned paper tubes by dust during the cleaning process, and ensuring that the cleanliness of the inner and outer surfaces of the paper tubes meets the strict requirements of the drying process for residual foreign matter. By coordinating the timing of pneumatic cleaning and mechanical sweeping, this solution optimizes airflow efficiency while ensuring cleaning effectiveness, solving the problems of incomplete dust removal and excessive energy consumption associated with traditional single-cleaning methods.

[0055] It should be noted that, optionally, a dust baffle is provided at the upper end of the paper tube body 100 at the rear end of the external cleaning mechanism 4. The dust baffle can shield this part of the paper tube body 100 from dust, and cooperate with the cleaning unit 42 to effectively prevent the dust blown up by the external cleaning mechanism 4 from falling back on the paper tube body 100 that is about to separate from the paper tube conveying mechanism 1.

[0056] Further, if Figure 1 、 Figure 10-11As shown, a driving mechanism 8 is also provided on one side of the lower feeding assembly 13, and the driving mechanism 8 includes a driving unit 82, which is fixedly set on the support platform 81; a driving gear 83 is transmission-set with the driving unit 82 and the driving gear 83 is transmission-connected with the driven gear 84; the driven gear 84 is transmission-set with the connecting rod 32 through a shaft sleeve 85, and the connecting rod 32 is threadedly connected to the shaft sleeve 85; a support rod 86 is fixedly set on the support platform 81 and the connecting rod 32 passes through the support rod 86.

[0057] After the drive unit 82 is started, it drives the active gear 83 to rotate. The active gear 83 engages with the driven gear 84 to cause the sleeve 85 to rotate synchronously. Since the connecting rod 32 and the sleeve 85 are threaded together, the rotation of the sleeve 85 forces the connecting rod 32 to move axially in a straight line. The support rod 86 constrains the movement trajectory of the connecting rod 32 to prevent motion errors caused by radial offset. As a result, the connecting rod 32 drives the cleaning head 31 of the internal cleaning mechanism 3 to accurately insert into the inner cavity of the paper tube and complete the inner wall cleaning action in a linear reciprocating motion. The threaded transmission structure controls the moving 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 synchronization of power transmission and avoids position deviation caused by transmission clearance.

[0058] Through the above technical solution, the present application realizes high-precision linear drive of the internal cleaning mechanism 3, ensures stable contact between the cleaning head 31 and the inner wall of the paper tube, and effectively removes attached foreign matter; the rigid connection between the gear and the threaded transmission avoids energy loss during power transmission, so that the cleaning action is strictly synchronized with the conveying rhythm, and prevents cleaning omissions caused by timing misalignment.

[0059] Further, if Figure 10-12 As shown, the driving mechanism 8 drives the intermittent feeding mechanism 2 to work through the transmission mechanism 9, and the transmission mechanism 9 includes a support plate 91, which is rotatably connected to one end of the connecting rod 32; a moving rod 92 is fixedly arranged at the lower end of the support plate 91 and is slidably arranged on the support platform 81; a rack condition 93 is fixedly connected to the outer side of the moving rod 92, and two groups of rack units 931 are arranged on the rack condition 93, and the rack unit 931 is transmission-connected to a transmission gear 94 rotatably arranged on the support platform 81; an active bevel gear 95 is coaxially arranged with the transmission gear 94 and is transmission-connected to a 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 rotationally connected to the support rod 86.

[0060] When the driving mechanism 8 drives the connecting rod 32 to rotate, the supporting plate 91 converts the rotational motion into a linear sliding of the moving rod 92, driving the rack member 93 to move along the supporting platform 81. The two sets of rack units 931 on the rack member 93 respectively mesh with the transmission gears 94 on both sides, causing the transmission gears 94 to rotate synchronously. The transmission gear 94 drives the coaxial driving bevel gear 95 to rotate. After the driving bevel gear 95 meshes with the driven bevel gear 96, the power is transmitted to the first rotating shaft 211, driving the vertical baffle 212 and the arc baffle 213 of the end feeding unit 21 to move; When the rack 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 re-limits the paper tube body 100. At the same time, the cleaning head 31 has completely withdrawn from the interior of the paper tube, and the arc-shaped baffle 213 is disengaged from the previous paper tube. This process ensures that the entry and exit of the cleaning head 31 are strictly synchronized with the release and blocking actions of the paper tube through the travel coordination of the rack and gear.

[0061] Through the above technical solution, the present application realizes the mechanical linkage control of the driving mechanism 8 and the intermittent feeding mechanism 2, ensuring that the paper tube enters the conveying state immediately after completing the inner wall cleaning, avoiding the risk of interference between the cleaning head 31 and the moving paper tube. At the same time, the bevel gear transmission structure accurately adjusts the power transmission direction, so that the first rotating shaft 211 and the support rod 86 form a stable rotation connection.

[0062] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
