[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Example 1: See Figure 1-Figure 9 A bamboo pulp sizing process and a sizing device thereof are supported by a frame 1, and a sizing tank 2 is fixed inside the frame 1 for containing bamboo slurry. A plurality of sizing units are arranged in the sizing tank 2, each unit comprising a sizing roller 13 and a pressure roller 4 located thereon, and when the sizing roller 13 is actively rotated, the yarn can pass through the sizing tank 2 along each roller.
[0026] Preferably, the pressure roller 4 can be arranged to slide, and the distance between the pressure roller 4 and the sizing roller 13 can be adjusted by matching the pressure roller 4 to adapt to different yarn thicknesses.
[0027] A reinforcement area is set on the side of the sizing unit, and the reinforcement area is used to enhance the efficiency of sizing. The reinforcement area is located between two sizing rollers 13, and can cooperate with pressure sizing to better complete the penetration inside the yarn. An injection unit is set in the reinforcement area, and the injection unit is composed of a plurality of independent installation boxes 5. A plurality of conical nozzles 6 are arranged in each installation box 5. The nozzle 6 is set at the top of the tube body 7 located in the installation box 5, and a piston 8 is set in the tube body 7.
[0028] The piston 8 in the tube body 7 is connected to the moving rod 9, and the piston 8 is repeatedly moved by controlling the moving rod 9. The installation box 5 and the nozzle 6 are arranged in the slurry. In order to enable normal use, a first one-way valve 11 is arranged between the nozzle 6 and the tube body 7. At the same time, the upper part of the tube body 7 is connected and penetrated by a connecting pipe 12. The connecting pipe 12 passes through the installation box 5 and the slurry tank 2 to communicate with the outside world, and a second one-way valve 13 is arranged in the connecting pipe 12. Specifically, the first one-way valve 11 is an outlet valve, and the second one-way valve 13 is an inlet valve. When the piston 8 moves downward, the gas enters the tube body 7 through the second one-way valve 13. When the piston 8 moves upward, the gas is ejected from the nozzle 6 to form a large number of bubbles near the yarn, which helps to better size the inside of the yarn.
[0029] When the slurry is not circulating, the injection unit is started, which will affect the quality of bubble generation. Therefore, a stirring unit is arranged at the bottom of the slurry tank 2, including a plurality of stirring impellers 14. The stirring impellers 14 penetrate the bottom of the slurry tank 2 through a connecting shaft 15. At the same time, each connecting shaft 15 is provided with a first pulley 33, and the first pulleys 33 are connected by belts, so that the two groups of stirring impellers 14 can be started synchronously, and the entire slurry tank 2 can be stirred to ensure the flow of bamboo pulp slurry therein.
[0030] Furthermore, in order to simultaneously control the synchronous rotation of the rotating shaft 18 and the connecting shaft 15, a first gear 16 is provided on the rotating shaft 18, and a control shaft 27 is connected to the second gear 17. The control shaft 27 passes through the frame 1 to set a connecting pulley 26, that is, when the stirring impeller 14 rotates, the connecting pulley 26 rotates synchronously.
[0031] The first gear 16 and the second gear 17 are both bevel gears. At the same time, the connecting pulley 26 drives the rotating shaft 18 after being connected to the connecting unit; the mounting box 5 is provided with a rotating shaft 18, the control unit includes a rotating shaft 18, a first spring 19 and a cam 20, and several moving rods 9 are connected by a connecting rod 21. The first spring 19 for resetting is arranged between the tube body 7 and the connecting rod 21 through the moving rod 9, and the rotating shaft 18 is located below the connecting rod 21. Several cams 20 are arranged on the rotating shaft 18. The rotating shaft 18 passes through the box body and the frame 1 to set a driving pulley 22. When the rotating shaft 18 rotates, the piston 8 and the moving rod 9 continue to reciprocate.
[0032] Specifically, the connecting unit includes a double-layer pulley 23, a driving pulley 22 and a control pulley 25. The control pulley 25 is concentrically connected to the double-layer pulley 23, and the driving pulley 22 is arranged on the outside of the double-layer pulley 23. At the same time, the driving pulley 22 and the control pulley 25 can be connected by a belt, and a clutch unit is arranged between the control pulley 25 and the double-layer pulley 23.
[0033] The clutch unit includes a first key sleeve 28, a second key sleeve 29 and a spline shaft 30, the first key sleeve 28 is concentrically connected to the control pulley 25, and the first key is rotatably connected to the side wall of the pulp groove 2 through a bracket 36. Furthermore, the control pulley 25 is connected to the first key sleeve 28. Similarly, the second key sleeve 29 is concentrically connected to the double-layer pulley 23 on the side wall of the pulp groove 2, wherein the double-layer pulley 23 rotates synchronously with the second key sleeve 29.
[0034] The spline shaft 30 is embedded and connected in the second key sleeve 29. Further, the spline shaft 30 is moved between the first key sleeve 28 and the second key sleeve 29. The control pulley 25 drives the double-layer pulley 23 to rotate. The rotating shaft 18 is provided with a driving pulley 22. The driving pulley 22 is respectively arranged at the grooves corresponding to the double-layer pulley 23. At the same time, the double-layer pulley 23 is connected to the driving pulley 22 through two sets of belts, that is, the double-layer pulley 23 drives the driving pulley 22 to rotate.
[0035] In the actual production process, the yarn needs to be reinstalled between the rollers, so the sizing roller 13 needs to be temporarily used, and the rotating shaft 18 is stopped at this time. Therefore, a starting unit is provided between the double-layer pulley 23 and the control pulley 25, and the starting unit is used to control the clutch unit. Specifically, the clutch unit includes the starting shell 37, a cutting piece 38 and a permanent magnet 39. At the same time, a second spring 31 and an electromagnet 32 are arranged in the second keyway. The spline shaft 30 is provided with a magnetic block corresponding to the electromagnet 32, and its magnetic pole relative to the energized electromagnet 32 is the same. When the electromagnet 32 is energized, the spline shaft 30 overcomes the second spring 31 and moves to, and the spline shaft 30 connects the first key sleeve 28 and the second key sleeve 29. Further, the starting unit is connected to the electromagnet 32. A shell 37 is arranged on the outside of the slurry groove 2. The shell 37 is arranged on the outside of the slurry roller 13, and is connected with a cutting piece 38 that rotates synchronously with the slurry roller 13. The permanent magnet 39 is distributed on the shell 37 to form a magnetic field. When the slurry roller 13 rotates, the cutting piece 38 cuts the magnetic field to generate current to supply the electromagnet 32, so that the electromagnet 32 drives the spline shaft 30 to connect.
[0036] Working principle: When the equipment is running, the motor drives the connecting shaft 15 to drive the stirring impeller 14 to rotate, and the stirring impeller 14 continuously stirs the inside of the slurry tank 2; the rotation of the control pulley 25 is realized through the cooperation of the first gear 16 and the second gear 17, and the stirring impeller 14 continuously stirs the inside of the slurry tank 2; At this time, the sizing unit is not working, and the spline shaft 30 is kept separated from the first key sleeve 28 under the action of the second spring 31 because the electromagnet 32 is powered off. After the yarn is shuttled through each roller to the sizing roller 13, the sizing roller 13 starts to rotate; The cutting member 38 coaxially mounted with the sizing roller 3 rotates accordingly, cutting the magnetic field formed by the permanent magnet 39 arranged on the side wall of the sizing tank 2, generating current to energize the electromagnet 32, so that the spline shaft 30 overcomes the spring resistance and engages with the first key sleeve 28. At this time, the control pulley 25 is connected to the double-layer pulley 23 through the spline shaft 30; After the rotating shaft 18 is driven to rotate by the connecting unit, the eccentric cam 20 rotates accordingly, periodically lifting the connecting rod 21, so that the moving rod 9 drives the piston 8 to reciprocate. The piston 8 inhales air through the second one-way valve 13 each time it returns, and the compressed air forms a bubble group through the nozzle 6 during the advancement. The micro-impact force generated by the bursting of the bubbles on the yarn surface causes the bamboo pulp to penetrate into the gaps between the yarn fibers.
[0037] Embodiment 2: Based on Embodiment 1, the spline shaft 30 is further improved, see Fig.10 The spline shaft 30 is provided with several shaft sections with different tooth densities. Specifically, the tooth density of the first shaft section 40 is greater than that of the second shaft section 41 , and the sealing of the teeth of the second shaft section 41 is greater than that of the third shaft section 42 .
[0038] The teeth density of the spline shaft 30 matched with the second key sleeve 29 is different. Different shaft sections are matched with the first key sleeve 28 to achieve different steam drum production intensities to prevent strong bubbles from impacting the yarn during chronic processing. The shaft section with a higher density is set closer to the second key sleeve 29.
[0039] At the same time, the rotation speed of the sizing roller changes, that is, the faster the rotation speed, the faster the rotating shaft 18 needs to rotate, that is, when the paddle wheel speed fluctuates, the current generated by the cutting piece 38 changes synchronously, and the magnetic force of the electromagnet 32 is adjusted accordingly, so that the second key sleeve 29 is connected to different shaft segments. Moreover, the faster the speed of the cutting piece 38, the greater the current, the greater the magnetic force of the electromagnet 32, and the denser the shaft segments are used in conjunction with the first key sleeve 28.
[0040] At the same time, after the sizing process is completed, the sizing roller stops rotating, the electromagnet 32 is powered off, the spline shaft 30 is reset under the action of the spring to disconnect the power transmission, and the stirring unit continues to work until the slurry tank 2 is emptied to avoid residual slurry precipitation.
[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
