Description

Technical Field

[0001] The invention relates to the technical field of sizing machines, in particular to a high-efficiency paper threading circuit for sizing machines. Background Art

[0002] In order to improve the quality of paper, glue will be evenly applied to the surface of the finished paper during processing to form an extremely thin waterproof layer, which greatly improves the water absorption, strength and tightness of the paper. Surface sizing of paper can not only meet the performance requirements of various special occasions, but also improve the physical strength, abrasion resistance, feel and paper surface smoothness and other defects of the paper. Papermaking sizing generally uses an immersion sizing machine or a film transfer sizing machine for paper sizing.

[0003] However, the existing sizing machine needs to leave the paper still until the film glue adheres to the paper and dries. The time for the glue on the paper to dry naturally is long, and it is time-consuming to remove it manually for drying or after natural drying, which affects the overall sizing efficiency.

[0004] In order to solve the above-mentioned defects, in the prior art, a Chinese patent with publication number CN221142309U discloses a film transfer sizing machine with uniform glue application, including a sizing cabinet, wherein a sizing assembly, a spraying assembly, a quick-drying assembly and a glue control assembly are installed in the sizing cabinet, two insulation plates are arranged between the sizing assembly and the quick-drying assembly, the sizing assembly includes two groups of sizing square tubes, the two groups of sizing square tubes are respectively fixed on the inner top and inner bottom of the sizing cabinet, multiple groups of nozzles are installed on the opposite sides of the two groups of sizing square tubes, and the two groups of sizing rollers are located between the two groups of sizing square tubes. The quick-drying component comprises two groups of quick-drying blow hoods, which are respectively fixed to the inner top and inner bottom of the gluing cabinet through fixing columns. By adding the design of the quick-drying component, when in use, after the glue film is attached to the paper by the glue application component, the paper is pulled between the two groups of quick-drying blow hoods through the driving component. At this time, the hot air blower is started to transport the airflow to the quick-drying blow hood through the three-way connecting pipe and the connecting air duct. After being heated and filtered by the filter, the slightly hot airflow is blown to the paper to quickly dry the paper with the film glue attached, thereby improving the gluing efficiency of the device.

[0005] In the prior art, a Chinese patent with publication number CN220008147U discloses an automatic glue applicator with uniform glue application, comprising a glue applicator frame, a workbench is provided above the glue applicator frame, and two wood pushing slots are provided on the workbench for facilitating the passage of wood, a chain conveyor is installed above one end of the frame away from the glue applicator frame, and a side vertical plate fixedly connected to the frame is provided on one side above the chain conveyor, and two limit columns are fixed on the other side above the chain conveyor, and the glue application component comprises a glue bucket, one side of which is connected to a glue application electric The machine is equipped with a gluing wheel, which is mounted on the output shaft of the gluing motor. The gluing wheel extends into an open groove on one side of the gluing bucket. When the wood moves in the pushing groove, the gluing motor drives the gluing wheel to rotate, and the colloid in the gluing bucket is coated on one side of the wood through the gluing wheel. Since the thickness of the gluing wheel is consistent with the depth of the wood pushing groove, the gluing quality of the wood is improved and the waste of glue is prevented. Since a pressure rod is provided, the transmission speed of the wood can be slowed down by the pressure of the pressure rod, thereby increasing the contact time with the gluing wheel, improving the uniformity of gluing and improving the gluing effect.

[0006] During use, the above-mentioned device uses a driving assembly to pull the paper to two sets of quick-drying blower hoods, thereby improving the drying efficiency. However, when the above-mentioned device adjusts the speed ratio during the paper feeding process, the speed cannot be well transmitted to the paper strip, resulting in the paper strip being too loose or the adjustment time being too long, thereby affecting the processing efficiency. Summary of the Invention

[0007] The object of the present invention is to provide an efficient paper threading circuit for a sizer to solve the problem in the background art that the paper strips are too loose and affect the processing efficiency.

[0008] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an efficient paper feeding circuit of a sizing machine, comprising a frame, a fixed seat is provided at the top of the frame, a cabinet is provided on the outer surface of the fixed seat, a stepping motor is provided on the outer surface of the cabinet, and the output end of the stepping motor is connected to a conveying mechanism for adjusting the tension; an air floating diverter is provided on the inner side surface of the cabinet, an adjusting roller is provided on the outer surface of the air floating diverter, a paper strip is provided on the outer surface of the adjusting roller, the paper strip is movably abutted against an arc roller, a connecting rod is provided on the outer surface of the arc roller, and brackets are provided on both sides of the connecting rod; a roller is provided on the outer surface of the paper strip, a support seat is provided on the outer surface of the roller, and a transmission cylinder of the same group is provided on the outer surface of the support seat, and the transmission cylinder of the same group is used to drive the paper feeding mechanism.

[0009] Furthermore, a rotating roller is provided on the inner side of the cabinet, and a conducting roller is provided on the inner side of the cabinet away from the rotating roller.

[0010] Furthermore, a driving roller 1 is movably mounted on the inner side of the cabinet, a driving roller 2 is provided on the inner side of the cabinet, and a guide plate is provided between the driving roller 2 and the conduction roller, and two groups of guide plates are provided.

[0011] Furthermore, the conveying mechanism includes an output shaft, an upper roller is provided on the outer surface of the output shaft, the upper roller is movably installed on the inner side of the cabinet, a gear 1 is provided on the end of the upper roller away from the output shaft, the gear 1 is meshed with the gear 2, and a lower roller is provided on the outer surface of the gear 2.

[0012] Furthermore, the angle of the air floating diverter is set to 90°.

[0013] Furthermore, a drying cylinder is provided on the outer surface of the support seat, and a roller is provided on the outer surface of the drying cylinder, and the drying cylinder is used to heat the roller.

[0014] Furthermore, the paper feeding mechanism includes a movable rod, which is rotatably mounted on the output end of the transmission cylinder of the same group, and is movably mounted on the inner side surface of the support seat.

[0015] Furthermore, a transmission roller is provided on the outer surface of the movable rod, and a transmission belt is provided on the outer surface of the transmission roller.

[0016] Furthermore, the conveyor belt is movably in contact with the inner side surface of the support seat, and the outer surface of the conveyor belt is wrapped with a drying net.

[0017] Furthermore, a positioning plate is provided on the outer surface of the lower roller, and the positioning plate is movably mounted on the outer surface of the cabinet.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The paper strip is driven to be transported by the provided conveying mechanism. During the transport, the angle of the provided air-floating diverter is adjusted to 90° so that the running direction of the paper strip is upward. The tension of the paper strip during transport is ensured by the cooperation of the conveying mechanism, the floating diverter and the paper-leading mechanism to avoid the paper strip being too loose or the adjustment time being too long, which affects the processing efficiency.

[0020] (2) During processing, the guide components provided in the cabinet are used to achieve stable transmission of the paper strips, avoiding deviation during transmission that affects the transmission of the paper strips. Under the guidance of the arc roller equipped with a bracket, the paper strips are transported to the paper guide mechanism. With the cooperation of the paper guide mechanism, wrinkles of the paper strips are avoided during transmission, thereby ensuring the smoothness of transmission;

[0021] (3) With the cooperation of the paper guide rope and the transmission mechanism, the overall path of the paper strip transmission is guided to ensure the stability of the tension of the paper strip during transmission, and the supporting loose rope pulley is used to ensure that the paper guide rope can be started and stopped independently, thereby achieving stable transmission of the paper strip and extending the service life of the paper rope;

[0022] (4) During the transmission process, the speed ratio of the transmission cylinders in the same group is adjusted through the operating table to keep the tension of the paper strip stable during this process. If the paper strip is too loose, the speed ratio is increased, and if the paper strip is too tight, the speed ratio is reduced until the paper strip passes through the transmission area of ​​the group smoothly, thereby improving the stability of the equipment;

[0023] (5) The paper strips are dried by the drying cylinder, and the drying cylinder and the conveyor belt cooperate with each other. The surfaces of the roller and the conveyor belt are wrapped with a dryer mesh. When the paper strips enter the transmission group, they can be well attached to the dryer mesh and the roller surface, making the transmission speed ratio adjustment more sensitive;

[0024] (6) The upper roller and the lower roller cooperate with each other to smoothly transmit the paper strip, and the positioning plate is used to position the lower roller to avoid falling off during transmission and affecting the transmission efficiency, thereby ensuring the stability of the equipment.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Example 1: Please refer to Figure 1-Figure 2 The present invention provides the following technical solution: an efficient paper feeding circuit of a sizing machine, comprising a frame 1, a fixed seat 2 is provided at the top of the frame 1, a cabinet 3 is provided on the outer surface of the fixed seat 2, a stepping motor 9 is provided on the outer surface of the cabinet 3, and an output end of the stepping motor 9 is connected to a conveying mechanism for adjusting the tension; an air floating diverter 16 is provided on the inner side of the cabinet 3, an adjusting roller 17 is provided on the outer surface of the air floating diverter 16, a paper strip 18 is provided on the outer surface of the adjusting roller 17, the paper strip 18 is movably abutted against an arc roller 19, a connecting rod 20 is provided on the outer surface of the arc roller 19, and brackets 21 are provided on both sides of the connecting rod 20; a roller 22 is provided on the outer surface of the roller 22, a support seat 24 is provided on the outer surface of the support seat 24, a transmission cylinder 25 of the same group is provided on the outer surface of the support seat 24, and the transmission cylinder 25 of the same group is used to drive the paper feeding mechanism.

[0038] During use, the paper strip 18 to be processed is guided through the feed port of the cabinet 3, passes through the guide components inside the cabinet 3, and then is discharged from the discharge port of the cabinet 3. The paper strip 18 is transported by the provided arc roller 19, and then the paper strip 18 is discharged under the transport of the paper guide mechanism, thereby realizing rapid processing of the paper strip 18.

[0039] First, by starting the stepper motor 9, the stepper motor 9 drives the conveying mechanism to convey the paper strip 18, and the air flotation diverter 16 is used to drive the adjustment roller 17 to adjust the angle, so that the paper web adjusted by the air flotation diverter 16 can be changed to an upward running direction (the figure shows the state before adjustment). The upward paper strip 18 is conveyed by the curved roller 19, and the curved roller 19 is fixed by the bracket 21. The paper strip 18 and the curved roller 19 maintain a wrap angle of 20°-25° before entering the same group of transmission cylinders 25 in the upper row. The paper strip 18 is conveyed by the provided paper guide mechanism, thereby achieving efficient processing of the paper strip 18.

[0040] When the air flotation diverter 16 is required to guide the paper, the fan installed in the air flotation diverter 16 (the air flotation diverter 16 is a prior art and will not be described in detail in this solution) is turned on at an appropriate frequency. At this time, an air film appears around the air flotation diverter 16, through which the paper strip 18 can be suspended in the air with a certain tension, and then enters the support seat 24 after passing through the arc roller 19. The speed ratio of the transmission cylinder 25 in the same group is controlled by the operating table (not shown in the figure, the operating table is a prior art and will not be described in detail in this solution) to keep the tension of the paper strip 18 stable during this process, thereby facilitating the adjustment of the tension of the paper strip 18. If the paper strip 18 is too loose, the speed ratio is increased, and if the paper strip 18 is too tight, the speed ratio is reduced to prevent the paper strip 18 from loosening during transmission and affecting the processing efficiency.

[0041] Example 2: Based on Example 1, please refer to Figure 3-Figure 6 , an air flotation diverter 16 is also disclosed, and its specific structure is as follows: a rotating roller 4 is provided on the inner side of the cabinet 3, a conduction roller 8 is provided on the inner side of the cabinet 3 away from the rotating roller 4, a drive roller 1 5 is movably installed on the inner side of the cabinet 3, a drive roller 2 6 is provided on the inner side of the cabinet 3, and a guide plate 7 is provided between the drive roller 2 6 and the conduction roller 8, and two groups of guide plates 7 are provided. The conveying mechanism includes an output shaft 10, an upper roller 11 is provided on the outer surface of the output shaft 10, and the upper roller 11 is movably installed on the inner side of the cabinet 3, and a gear 12 is provided at one end of the upper roller 11 away from the output shaft 10, and the gear 12 is meshed with the gear 2 13. The outer surface of the gear 2 13 is provided with a lower roller 14, and the angle of the air flotation diverter 16 is set to 90°.

[0042] When the paper strip 18 enters from the feed port of the cabinet 3, Figure 3 As can be seen, the paper strip 18 passes from the rotating roller 4 along the top of the driving roller 1 5, then passes under the driving roller 2 6, and is conveniently conducted by the two sets of guide plates 7. The paper strip 18 then passes under the conducting roller 8 and is transferred between the upper roller 11 and the lower roller 14, thereby avoiding deviation during transmission and ensuring the smoothness of the paper strip 18 during transmission.

[0043] By starting the stepper motor 9, Figure 4It can be seen that the stepper motor 9 drives the output shaft 10 to rotate, the output shaft 10 drives the upper roller 11 to rotate, the upper roller 11 drives the gear 12 and the gear 2 13 to mesh and operate, and the gear 2 13 drives the lower roller 14 to rotate, and the positioning plate 15 is provided to position the lower roller 14 to prevent the lower roller 14 from falling off during operation and causing damage to the equipment. Under the cooperation of the upper roller 11 and the lower roller 14, the paper strip 18 is stably transmitted, thereby achieving the purpose of rapid transmission, and the paper strip 18 passes under the adjusting roller 17 and is then transmitted through the arc roller 19 to avoid wrinkles during transmission;

[0044] During transmission, the angle of the air flotation diverter 16 is adjusted to 90°. Compared with the traditional 45°, the angle of the air flotation diverter 16 is increased, so that the adjustment roller 17 drives the paper strip 18 to maintain the upward running direction, and the paper strip 18 is conveyed backward under the clamping of the paper guide rope. The paper guide rope is located below the paper strip 18 to assist in transporting the paper strip 18. In order to ensure the service life of the paper guide rope, the paper guide rope used shares the transmission path of the cabinet 3. The air flotation diverter 16, the curved roller 19 and each cylinder (drying cylinder 23, the same group of transmission cylinders) that is driven after gluing are equipped with a loose rope pulley on the operating side (the paper guide rope and the loose rope pulley are not shown in the figure and are existing technology, so this solution will not elaborate on them in detail) to ensure that the paper guide rope can be started and stopped independently to ensure the stability of the equipment transmission.

[0045] Example 3: Based on Example 1, please refer to Figures 5-10 , a roller 22 is also disclosed, and its specific structure is as follows: a drying cylinder 23 is provided on the outer surface of the support base 24, and a roller 22 is provided on the outer surface of the drying cylinder 23. The drying cylinder 23 is used to heat the roller 22, and the paper feeding mechanism includes a movable rod 26. The movable rod 26 is rotatably mounted on the output end of the transmission cylinder 25 of the same group, and the movable rod 26 is movably mounted on the inner side surface of the support base 24. The outer surface of the movable rod 26 is provided with a transmission roller 27, and the outer surface of the transmission roller 27 is provided with a transmission belt 28. The transmission belt 28 is movably abutted against the inner side surface of the support base 24, and the outer surface of the transmission belt 28 is wrapped with a dry net. The outer surface of the lower roller 14 is provided with a positioning plate 15, and the positioning plate 15 is movably mounted on the outer surface of the cabinet 3.

[0046] When the paper strip 18 passes through the curved roller 19 equipped with the bracket 21, Figure 10 It can be seen that the paper strip 18 then enters the transmission cylinder 25 of the same group, and the paper guide mechanism is used to transmit the paper strip 18. By starting the transmission cylinder 25 of the same group, the transmission cylinder 25 of the same group drives the movable rod 26 to rotate, the movable rod 26 drives the transmission roller 27 to rotate, and the transmission roller 27 drives the transmission belt 28 to rotate, thereby transmitting the paper strip 18.

[0047] And start the drying cylinder 23 at the same time of transmission, Figure 5It can be seen that the roller 22 is heated by the drying cylinder 23, and the paper strip 18 is dried while being transmitted through the mutual cooperation of the roller 22 and the conveyor belt 28, and the surface of the conveyor belt 28 is wrapped with a dryer mesh, so that the paper strip 18 can be well attached to the dryer mesh and the surface of the roller 22 after entering this group of transmissions, making the speed ratio adjustment of the transmission more sensitive, and realizing more sensitive speed ratio adjustment of the paper feeding process, so that the paper strip 18 can enter the sandwiching area of ​​the dryer mesh faster, so that the transmission stability of the paper strip 18 is better, and the paper feeding efficiency can be greatly improved.
