Description

Technical Field

[0001] The invention belongs to the technical field of spinning, and in particular relates to a quick-detachable energy-saving ring-blowing device for polyester staple spinning. Background Art

[0002] The melt spinning process involves heat transfer during the cooling and solidification of the filaments. The production process requires the cooling device to provide the most favorable forming conditions. Existing cooling devices on the market are categorized into center-blown, side-blown, and ring-blown. Ring-blown devices are currently the most commonly used cooling device because they generally provide better air uniformity, use less air volume, and save energy compared to center-blown and side-blown devices.

[0003] As new varieties of polyester staple spinning products place higher demands on cooling devices, existing ring-blowing devices generally have some defects. For example, in the case of different spinning raw materials, the melt state when ejected from the spinneret is different, and different cooling air is required, but the ring-blowing devices are also different, resulting in a production line that can only spin a single variety, and multiple fiber varieties cannot be spun on the same equipment. This situation can no longer meet the requirements for the development of new processes and new products in polyester staple fibers; the straightening cylinder is a device that directly affects the airflow. Conventional ring-blowing devices need to replace the straightening cylinder according to different spinning processes, and conventional annular air chambers are fixed with screws. It takes a long time to disassemble and install the screws when replacing the straightening cylinder, and the labor intensity of the operator is high. Therefore, a quick-disassembly and energy-saving ring-blowing device is proposed to solve the above problems. Summary of the Invention

[0004] In view of the above problems, the present invention provides a quick-disassembly energy-saving ring-blowing device for polyester staple spinning, which is used to solve the problems that conventional ring-blowing devices can only be used for one type of spinning, have a long disassembly and assembly time, and are inconvenient to operate.

[0005] To achieve the above object, the technical solution adopted by the present invention is: A quick-detachable energy-saving ring-blowing device for polyester staple spinning, comprising a lower air chamber interconnected with an air source, an upper air chamber detachably provided above the lower air chamber, and a rectifier assembly detachably provided in the upper air chamber; A rotating ring is rotatably provided on the lower air chamber, and a locking ring which can be clamped and sealed with the rotating ring is fixedly provided on the joint surface of the upper air chamber and the lower air chamber; The bottom surface of the rectifier assembly is in contact with the lower air chamber. After the upper air chamber is clamped downward with the lower air chamber, the rectifier assembly is fixed between the lower air chamber and the upper air chamber. The wind direction on the rectifier assembly is toward the center of the lower air chamber, and the wind direction on the rectifier assembly has horizontal blowing and side blowing inclined upward or downward.

[0006] As a further improvement to the above solution, a porous plate is fixedly provided at the top air outlet position of the lower air chamber, and an air regulating plate cooperating with the porous plate is movably provided on the upper side of the porous plate; The bottom of the rectifier assembly is in line contact with the lower air chamber, and a transfer seat is fixedly provided on the bottom of the rectifier assembly, and the bottom of the transfer seat is engaged with the air regulating plate.

[0007] As a further improvement of the above solution, the rectifier assembly includes end plates arranged on the upper and lower sides, and the first air uniform plate, the second air uniform plate, and the air guide assembly are detachably arranged between the end plates from the outside to the inside; The air guide assembly is provided with flow channels for blowing out horizontal air as well as air inclined upward or downward.

[0008] As a further improvement of the above solution, the air guide assembly is formed in one piece, and the flow channel is a through hole arranged on the air guide assembly toward the central axis.

[0009] As a further improvement of the above solution, the air guide assembly is formed by a plurality of sleeves that are stacked and socketed with each other, a plurality of first perforations are provided in the sleeves, and the plurality of first perforations are combined together to form a flow channel.

[0010] As a further improvement to the above solution, the sleeve is further provided with second through-holes, which are aligned with each other and are fixed by fixing pins passing through them; The sleeves fit tightly against each other.

[0011] As a further improvement of the above solution, a first mounting groove is provided on the end plate, and an adjustment top seat is detachably provided in the first mounting groove. The adjustment top seat supports the sleeve to change the height of different sleeves.

[0012] As a further improvement of the above solution, the air guide assembly includes a first connecting seat and a second connecting seat that are socketed with each other. The first connecting seat and the second connecting seat are connected by an air guide pipe, and the interior of the air guide pipe is a flow channel.

[0013] As a further improvement to the above solution, a second mounting groove is provided on the lower end plate, and an elastic seat is detachably provided in the second mounting groove, and the elastic seat can be elastically deformed to press against the first connecting seat; An adjusting ring is rotatably provided in the upper air chamber, and a pressing platform is provided on the adjusting ring, which contacts downward with the surface of the first connecting seat penetrating the end plate.

[0014] As a further improvement of the above solution, the invention further comprises a mounting frame, wherein the mounting frame is provided with a telescopic tube interconnected with the lower air chamber, the upper air chamber and the mounting frame are slidably arranged with each other, and the mounting frame is provided with a driving source for driving the mounting frame to move up and down; A clamping seat for clamping and fixing the lower air chamber is also provided on one side of the mounting frame.

[0015] Compared with the prior art, the present invention has the following beneficial effects: By providing a locking ring and a rotating ring, the lower air chamber and the upper air chamber can be quickly clamped, which reduces the working time of replacing or adjusting the rectifier assembly and facilitates disassembly and assembly. In the process of replacing the rectifier assembly, the lower air chamber is clamped by the clamping seat. After the locking ring and the rotating ring are unlocked, the lower air chamber and the upper air chamber can be separated by driving the driving cylinder, thereby making it more convenient to disassemble without the need for long-term operations such as loosening and tightening screws.

[0016] By setting up the porous plate and air regulating plate, the air intake volume can be controlled according to the silk threads of different materials. Moreover, under the action of rotating the rectifier component, the adapter and the air regulating plate can be driven to rotate synchronously, and the porous plate and the air regulating plate can rotate to change the size of the gap, thereby facilitating the adjustment of the air intake volume.

[0017] The flow channel on the rectifier assembly is set up to blow horizontal air toward the middle, and it can also blow inclined air. Therefore, the blowing direction of the flow channel can be adjusted according to the material of the silk thread to achieve blowing of wind of corresponding direction for different silk threads, thereby improving the quality of the silk thread; especially when more cooling effect is needed, the direction of the flow channel is tilted upward, so that the blowing air can be closer to the spinneret position, so that the silk thread just ejected can receive the cooling air immediately, and the cooling effect is faster. On the contrary, when less cooling effect is needed, the direction of the flow channel is tilted downward, the time for the silk thread to receive the cooling air will increase, and the cooling effect of the silk thread will be reduced. The wind blown completely horizontally can easily collide with each other to produce turbulence, which can easily cause the silk thread to shake and float, resulting in reduced silk thread quality. The collision effect of the obliquely sprayed wind is reduced, and it is easy to form an airflow in the same or tangential direction as the silk thread, which makes it easier to maintain a stable air pressure in the silk thread channel during work and reduce silk thread defects.

[0018] When using an integrally manufactured air guide component, when selecting the wind direction, the lower air chamber and the upper air chamber are disassembled, and the air guide component is installed in a U-turn. Similarly, when using an integral air guide component manufactured by a sleeve, the wind direction is also selected by turning the assembly around. When using a movable sleeve and a first connecting seat and a second connecting seat structure, only adjustments need to be made, such as adjusting the top seat and the adjustment ring. By adjusting and using different structures and blowing effects according to different materials and the required cooling effect, the purpose of energy saving can be achieved.

DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the technical solution, the present invention is described in detail below in conjunction with embodiments. The description in this section is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0022] Example 1

[0023] like Figure 1-10As shown, the specific solution of this embodiment is: a quick-release energy-saving ring-blowing device for polyester staple spinning, including a lower air chamber 10 interconnected with an air source, such as Figure 1 As shown, an upper air chamber 11 is detachably provided above the lower air chamber 10, and a rectifier assembly 12 is detachably provided in the upper air chamber 11. After the lower air chamber 10 and the upper air chamber 11 are separated, the rectifier assembly 12 can be taken out of the upper air chamber 11 for replacement and other operations; A rotating ring 14 is provided on the lower air chamber 10, and a locking ring 13 which can be clamped and sealed with the rotating ring 14 is fixed on the joint surface of the upper air chamber 11 and the lower air chamber 10. Figure 2 、 4 As shown, when installing, the locking ring 13 and the rotating ring 14 are first aligned with each other, and then the rotating ring 14 is rotated. That is, the locking ring 13 and the rotating ring 14 can be locked with each other. A sealing ring is provided on the rotating ring 14 to reduce outward leakage during blowing. The mounting frame 22 is also provided with a telescopic tube 23 which is interconnected with the lower air chamber 10. The upper air chamber 11 and the mounting frame 22 are arranged to slide with each other. Specifically, a linear bearing is provided on the upper air chamber 11 to realize the up and down lifting movement that slides with the mounting frame 22. The mounting frame 22 is provided with a driving source for driving the mounting frame 22 to move up and down. In this embodiment, the driving source is a driving cylinder, and the output shaft of the cylinder is fixed to the upper air chamber 11. A clamping seat 24 is also provided on one side of the mounting frame 22 for clamping and fixing the lower air chamber 10.

[0024] In the specific process of replacing the rectifier assembly 12, as shown in FIG. Figure 1 The figure shows the state during normal operation. When replacing, the driving cylinder first drives the lower air chamber 10 and the upper air chamber 11 to move downward until the lower air chamber 10 contacts the clamping seat 24, and then the lower air chamber 10 is clamped by the clamping seat 24. After clamping, the rotating ring 14 is rotated to separate the lower air chamber 10 and the upper air chamber 11. Then, the driving cylinder is controlled to drive the upper air chamber 11 to rise upward. At this time, the lower air chamber 10 and the upper air chamber 11 are separated from each other, and the rectifier assembly 12 is exposed for replacement. After the rectifier assembly 12, the driving cylinder drives the upper air chamber 11 to move downward to cover the rectifier assembly 12, and dock with the lower air chamber 10. After fastening through the locking ring 13 and the rotating ring 14, the clamping seat 24 is released, and the cylinder drives the upper air chamber 11 and the lower air chamber 10 to move upward again to become a normal working state. Therefore, this replacement method only requires manual unlocking and fastening of the lower air chamber 10 and the upper air chamber 11 and replacement of the rectifier assembly 12, which can reduce a lot of disassembly and installation time and is more efficient.

[0025] In order to adapt to different silk threads, in this embodiment, the bottom surface of the rectifying assembly 12 is in contact with the lower air chamber 10, and after the upper air chamber 11 is clamped downward with the lower air chamber 10, the rectifying assembly 12 is fixed between the lower air chamber 10 and the upper air chamber 11, and the wind direction on the rectifying assembly 12 is toward the axis of the lower air chamber 10, and the wind direction on the rectifying assembly 12 has horizontal blowing and upward or downward inclined side blowing. Because different silk threads require different cooling amounts, the cooling time of the silk thread can be increased by blowing in different directions on the rectifying assembly 12. That is, for silk threads that require more cooling, the blowing is inclined upward, which can make the silk thread that has just come out of the spinneret cool immediately, while for silk threads that do not need more cooling, the blowing is inclined downward to ensure uniform cooling. At the same time, setting the wind direction to an inclined state can effectively reduce turbulence in the silk thread channel, reduce the shaking of the silk thread, and improve the quality of the silk thread.

[0026] As a preferred embodiment of the above, in order to adjust the air volume for different silk threads, in this embodiment, a porous plate 15 is fixedly provided at the top air outlet position of the lower air chamber 10, and an air regulating plate 16 that cooperates with the porous plate 15 is movably provided on the upper side of the porous plate 15. Figure 9 、 10 ; There is line contact between the bottom of the rectifying assembly 12 and the lower air chamber 10, and an adapter seat 17 is fixedly provided at the bottom of the rectifying assembly 12, and a sealing gasket is provided between the adapter seat 17 and the rectifying assembly 12, and the bottom of the adapter seat 17 and the air regulating plate 16 are engaged with each other. Specifically, by arranging line contact between the bottom of the rectifying assembly 12 and the lower air chamber 10, the friction between the rectifying assembly 12 and the lower air chamber 10 can be reduced, and the bottom of the rectifying assembly 12 and the adapter seat 17 are connected to each other through a card slot, and the air regulating plate 16 and the adapter seat 17 are also connected to each other through a card slot, and a sealing gasket is also provided between the two. By rotating the rectifying assembly 12, the synchronous rotation of the air regulating plate 16 and the adapter seat 17 can be achieved, thereby achieving the purpose of facilitating the adjustment of the air volume. With this arrangement, the position of the air regulating plate 16 can be adjusted by the rectifying assembly 12, which is easier to control and more convenient to adjust during the adjustment process.

[0027] like Figure 5 As shown, as a preferred embodiment of the above embodiment, the rectifier assembly 12 includes end plates 1201 arranged on the upper and lower sides, and the first wind uniforming plate 1202, the second wind uniforming plate 1203, and the wind guide assembly 1204 are detachably arranged between the end plates 1201 from the outside to the inside; the wind guide assembly 1204 is provided with a flow channel 1205 for blowing out horizontal and upward or downward inclined air.

[0028] like Figure 6As shown, as the first embodiment of the air guide component 1204 in the present invention, the air guide component 1204 is formed in one piece, and the flow channel 1205 is a through hole arranged on the air guide component 1204 toward the central axis. The flow channel 1205 has a certain thickness. When arranging the flow channel 1205, inclined and horizontal punching are selected.

[0029] like Figure 7 As shown in the figure, as a second embodiment of the air guide component 1204 of the present invention, in this embodiment, the air guide component 1204 is formed by a plurality of sleeves 1206 that are stacked together. The sleeve 1206 is specifically a thin pipe. The thickness of the air guide component 1204 in embodiment 1 is achieved by stacking a plurality of sleeves 1206. A plurality of first through-holes 1207 are provided in the sleeve 1206. The plurality of first through-holes 1207 are combined to form a flow channel 1205. Specifically, the first through-holes 1207 are provided. From the straight hole, when multiple first perforations 1207 that are not in the same position are stacked together, the effect of an inclined hole can be formed. A second perforation 1208 is also provided on the sleeve 1206. The second perforations 1208 are aligned with each other and are fixed through a fixing pin 1209; the sleeves 1206 fit tightly together, and the sleeves 1206 fit tightly together to prevent wind from blowing out from the gaps in the sleeves 1206. The main purpose of setting the sleeve 1206 is to save manufacturing costs, and the effect achieved is the same as Figure 6 The embodiments are the same. In these two embodiments, the process of adjusting the wind direction is to turn the rectifier assembly 12 around. Because the flow channel 1205 on the wind guide assembly 1204 is not only inclined but also horizontal, after turning around, the inclined flow channel 1205 can change direction, while the horizontal flow channel 1205 still discharges air horizontally, which can be suitable for different products while ensuring better use effects.

[0030] like Figure 8 As shown, as the third embodiment of the air guide component 1204 in the present invention, a first mounting groove 1210 is provided on the end plate 1201, and an adjustment top seat 1211 is detachably provided in the first mounting groove 1210. The adjustment top seat 1211 supports the sleeve 1206 to change the height of different sleeves 1206. Specifically, the adjustment top seat 1211 is a support ring with a replaceable shape. The top surface of the adjustment top seat 1211 can generally be set to an inclined surface or a flat surface. In this embodiment, a flat surface is set. Since the sleeve 1206 is a plurality of sleeves stacked together, when the sleeve 1206 contacts the top surfaces of different adjustment top seats 1211, the height of the sleeve 1206 changes differently, so that the first perforation 1207 presents flow channels 1205 with different inclinations to achieve control of the air outlet direction.

[0031] Example 2

[0032] like Figure 11-14 As shown, as the second embodiment of the present invention, this embodiment mainly improves the structure of the upper air chamber 11 and the rectifying assembly 12 in Example 1. The improvement of the rectifying assembly 12 mainly lies in the air guide assembly 1204. Specifically, in this embodiment, the air guide assembly 1204 includes a first connecting seat 12041 and a second connecting seat 12042 that are socketed with each other. The first connecting seat 12041 and the second connecting seat 12042 are connected by an air guide pipe 19. The interior of the air guide pipe 19 is a flow channel 1205, and the air guide pipe 19 is a set hose. Therefore, in this embodiment, the flow channel 1205 is arranged in the form of the air guide pipe 19, which can further reduce costs; and in this embodiment, a second mounting groove 20 is provided on the lower end plate 1201, and an elastic seat 21 is detachably provided in the second mounting groove 20. The elastic seat 21 can elastically deform and press the first connecting seat 12041. When the first connecting seat 12041 moves up and down, the up and down tilt position of the air guide pipe 19 can be changed; The improvement of the upper air chamber 11 is mainly that an adjusting ring 18 is rotatably provided in the upper air chamber 11, and a tooth is provided on the edge of the adjusting ring 18. The adjusting ring 18 is also provided with a top pressure platform 181 that contacts the surface of the first connecting seat 12041 that penetrates the end plate 1201 downward. Figure 14 As shown, the pressing platform 181 is in a "C" structure with an opening downward, and the surface in contact with the first connecting seat 12041 is arranged in an inclined surface. The first connecting seat 12041 and the end plate 1201 can also rotate relative to each other within a small range. Therefore, when it is necessary to adjust the wind direction according to the silk thread, it is only necessary to use a key or wrench to engage with the adjusting ring 18 and rotate it for adjustment. When the adjusting ring 18 rotates, it can make the pressing platform 181 and the top of the first connecting seat 12041 move relative to each other. When the contact surface is arranged in an inclined manner, the first connecting seat 12041 can be pressed downward or lifted upward under the action of the elastic seat 21, thereby realizing the up and down movement of the first connecting seat 12041, thereby achieving the purpose of controlling the up and down change of the wind direction.

[0033] It should also be noted that during the rotation of the adjusting ring 18, the first connecting seat 12041 can be driven to rotate a short distance relative to the air guide assembly 1204 under the action of the pressing platform 181, so that the wind blown out from the air guide pipe 19 can be blown out in a spiral shape around the center, which can effectively reduce the phenomenon of wind direction blowing when cooling the silk thread and reduce the collision of air flows. The cooling wind blown out by the swirl can increase the contact time with the silk thread, while maintaining the stability of the silk thread from spraying, cooling to oiling, and further improving the cooling effect; on the other hand, in the process of continuous rotation of the adjusting ring 18, the first connecting seat 12041 can be synchronously driven to rotate the entire rectifier assembly 12. Due to the mutually fixed relationship between the rectifier assembly 12 and the adapter seat 17 and the air regulating plate 16, the air intake volume can be adjusted without separating the lower air chamber 10 and the upper air chamber 11.

[0034] It should be noted that, in this article, the terms include, comprise or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. Specific examples are used herein to illustrate the principles and implementation methods of the technical solution of the present invention. The above examples are only used to help understand the method of the present invention and its core idea. The above is only a preferred embodiment of the present invention. It should be pointed out that due to the limitations of textual expression and the objective existence of infinite specific structures, ordinary technicians in this technical field can make several improvements, modifications or changes without departing from the principles of the present invention, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the inventive concept and technical solution to other occasions without improvement, should all be regarded as the scope of protection of the present invention.
