Description

TECHNICAL FIELD

[0001] The application relates to the technical field of chemical fiber filament production equipment, in particular to a tension automatic adjusting winding device for chemical fiber filament processing. BACKGROUND

[0002] The chemical fiber filament is a fiber with textile performance prepared by taking natural high molecular compounds or artificially synthesized high molecular compounds as raw materials and through processes such as preparation of spinning solution, spinning and post-treatment.

[0003] In the process of chemical fiber filament production, the produced chemical fiber filament needs to be wound, and the winding equipment is generally driven by a motor. However, the motor may cause the winding equipment to have an unstable rotating speed due to various factors such as heat and voltage of the motor, so that when the chemical fiber filament is discharged at a high speed, the winding tension of the chemical fiber filament is large and the chemical fiber filament is prone to breakage, and when the chemical fiber filament is discharged at a low speed, the winding tension of the chemical fiber filament is small and the winding is loose, which may even cause the formed product to have a collapsed edge. The existing device uses a winding drum in cooperation with a spring mechanism to slow down for a short time, but the adjusting range is small, and the rotating speed of the winding equipment cannot be directly and adaptively adjusted, so the problem cannot be fundamentally solved, and the chemical fiber filament may still be broken and the winding may be loose when the chemical fiber filament is discharged at a high or low speed for a long time.

[0004] Therefore, the applicant proposes a tension automatic adjusting winding device for chemical fiber filament processing. SUMMARY

[0005] The application aims to solve the problem that the winding tension of the chemical fiber filament is large when the chemical fiber filament is discharged at a low speed, and the chemical fiber filament is prone to breakage, and the winding is loose when the chemical fiber filament is discharged at a high speed.

[0006] The tension of the chemical fiber filament can be automatically controlled in real time, and the release of compressed gas tank gas and the restoring force of the torsion spring can be matched, so that the chemical fiber filament can be automatically adjusted in real time when the tension of the chemical fiber filament is large or small, so that the chemical fiber filament can be effectively stabilized in a certain tension range, and when the tension of the chemical fiber filament is too large or too small, the rotating valve core is rotated to a large extent, the gas transmission is large, the moving magnetic plug is pressed by the driving button, and the rotating speed of the winding drum can be effectively adjusted, so that the problem that the chemical fiber filament is broken or the bobbin is loose due to too large or too small tension of the chemical fiber filament is further slowed down. Compared with the existing winding mode, the device has a large adjustment range, and can further adjust the winding loose state according to different situations to improve the appearance and quality of the chemical fiber filament bobbin, so as to facilitate the smooth unwinding of the subsequent weaving, warp knitting and other processes.

[0008] Optionally, two valve housings are installed inside the two telescopic pipes, a moving magnetic plug is slidably connected inside the valve housing, a through hole is drilled on the valve housing, a driving button electrically connected with the winding drum is installed on the inner wall of the valve housing, and a one-way valve is installed on the valve housing to facilitate the exhaust of the telescopic pipe.

[0010] Optionally, two magnetic strips are installed on the rotating valve core, and the magnetic strips are magnetically attracted to the moving magnetic plug, which can help the other telescopic pipe to compress and exhaust when one of the telescopic pipes is expanded and elongated.

[0011] Optionally, the two magnetic strips are located in opposite directions of the air holes of the sliding block.

[0012] Optionally, the included angle between the two air holes in the valve housing is 45°, which is conducive to controlling the tension of the chemical fiber filament in the middle range.

[0014] Optionally, a magnet is installed inside the magnetic rod plug, and the magnetic rod plug is magnetically attracted to the moving magnetic plug through the magnet, which can utilize the magnetic force to control the two telescopic pipes to be in the air state, and facilitate the resetting of the sliding block.

[0015] Optionally, the air hole on the sliding block has a larger diameter than the through hole, and when the air hole of the rotating valve core and the air hole on the sliding block are completely matched, the sliding block is moved at a speed that is too fast, so that the gas can push the moving magnetic plug.

When the tension of the chemical fiber filament is too large or too small, the rotating valve core has a large rotating amplitude, which causes a large gas transmission, drives the moving magnetic plug to press the drive button, and further adjusts the speed of the winding drum, further slows down the problem of chemical fiber filament breakage or loose winding of the cheese caused by excessive tension or small tension. Compared with the existing winding method, the device has a large adjustment range and can further adjust the winding relaxation state according to different situations to improve the appearance and quality of the chemical fiber filament cheese, and facilitate the smooth unwinding of the subsequent weaving, warp knitting and other processes.

[0018] (2) The sliding block and the inner wall of the sliding plate are fixedly connected with two elastic ropes, which can help the sliding block to reset by using the tension of the elastic rope and the gravity of the sliding block.

[0019] (3) Two valve housings are installed in the two telescopic pipes of the sliding block, a moving magnetic plug is slidably connected in the valve housing, a through hole is opened in the valve housing, a drive button electrically connected with the winding drum is installed on the inner wall of the valve housing, and a one-way valve is installed on the valve housing to facilitate the exhaust of the telescopic pipe.

[0020] (4) The drive button on the upper side of the connecting rod controls the speed reduction of the winding drum, and the drive button on the lower side controls the speed increase of the winding drum, which can slow down to a certain extent when the tension of the chemical fiber filament is too large or too small.

[0021] (5) Two magnetic strips are installed on the rotating valve core of the compressed gas tank, and the magnetic strips are magnetically attracted to the moving magnetic plug, which can help the other telescopic pipe to compress and exhaust when one of the telescopic pipes is expanded and elongated.

[0022] (6) The two magnetic strips of the valve housing are located in the opposite directions of the air holes of the sliding block.

[0023] (7) The included angle of the two air holes in the magnetic rod plug valve housing is 45°, which is conducive to controlling the tension of the chemical fiber filament within a moderate range.

[0025] (9) The magnetic rod plug is internally provided with a magnet, and the magnetic rod plug is magnetically attracted to the moving magnetic plug through the magnet, so that the two telescopic pipes can be controlled in a ventilation state by using magnetic force, and the sliding block is conveniently reset.

[0026] (10) The caliber of the ventilation hole on the sliding block is larger than that of the through hole, when the air hole of the rotating valve core and the ventilation hole on the sliding block completely correspond, the sliding block is moved at too high a speed, so that the gas can sufficiently push the moving magnetic plug.

[0042] Please refer to Figures 1-2 In use, sliding block 3 is pulled under the pull of elastic rope 8, and then cooperate with the gravity of sliding block 3 itself, so that sliding block 3 can stay in the middle position of sliding plate 2 in standby state, when winding of winding drum 11 makes the tension of chemical fiber filament larger, electric power rail 41 is pressed, rotatable valve core 31 is rotated through connecting rod 4, so that rotatable valve core 31 is not communicated with expansion tube 21, as Figure 7 When the tension of chemical fiber filament is larger due to winding of winding drum 11, chemical fiber filament will press electric power rail 41, so that air hole 311 is communicated with upper expansion tube 21, and then under the air thrust of compressed gas tank 5, expansion tube 21 is expanded and elongated, sliding block 3 is driven to move downward, to avoid chemical fiber filament from being disconnected due to excessive tension, when the tension of chemical fiber filament is smaller, chemical fiber filament is in relaxed state, at this time, rotatable valve core 31 is rotated upward under the restoring force of torsion spring 32, so that rotatable valve core 31 is communicated with lower expansion tube 21, so that lower expansion tube 21 is expanded and elongated, sliding block 3 is driven to move upward, until rotatable valve core 31 is not communicated with expansion tube 21 due to the rotation of chemical fiber filament, so as to keep chemical fiber filament in stable tension range, asFigures 1-2 As shown.

[0043] Please refer to Figure 7 , the sliding block 3 and the inner wall of the slide plate 2 are fixedly connected with two elastic ropes 8, two telescopic pipes 21 are internally provided with two valve housings 6, the valve housing 6 is internally slidably connected with a moving magnetic plug 61, the valve housing 6 is provided with a through hole 62, the valve housing 6 is internally provided with a drive button 63 electrically connected with the winding drum 11, the valve housing 6 is provided with a check valve 64, the upper drive button 63 controls the winding drum 11 to slow down, the lower drive button 63 controls the winding drum 11 to speed up, the rotating valve core 31 is provided with two magnetic strips 312, and the magnetic strips 312 are magnetically attracted to the moving magnetic plug 61, the two magnetic strips 312 are located in the opposite directions of the air holes of the sliding block, the included angle between the two air holes in the valve housing 6 is 45°, and the air hole on the sliding block 3 has a larger diameter than the through hole 62.

[0044] When the rotating valve core 31 rotates and communicates with the upper telescopic pipe 21, the magnetic strip 312 is attracted to the moving magnetic plug 61 of the lower telescopic pipe 21, so that the moving magnetic plug 61 moves upward, as Figure 8 shown, when the sliding block 3 moves downward, the air in the lower telescopic pipe 21 is discharged through the check valve 64, and conversely, when the sliding block 3 moves upward, the air in the upper telescopic pipe 21 is also discharged through the check valve 64.

[0045] Please refer to Figures 8-10 , when the tension of the chemical fiber filament is large or small, the air hole 311 of the rotating valve core 31 does not completely correspond to the air hole on the sliding block 3, so that the transmission flow of the gas released by the compressed gas tank 5 is small, the moving speed of the sliding block 3 is slow, and therefore the gas is not enough to push the moving magnetic plug 61 to press the drive button 63, and when the tension of the chemical fiber filament is too large or too small, the air hole 311 of the rotating valve core 31 completely corresponds to the air hole on the sliding block 3, and the sliding block 3 moves too fast, so that the gas is enough to push the moving magnetic plug 61 to press the drive button 63, when the upper drive button 63 is pressed, the winding drum 11 is controlled to slow down, thereby slowing down the case that the tension of the chemical fiber filament is too large, and when the lower drive button 63 is pressed, the winding drum 11 is controlled to speed up, thereby slowing down the case that the tension of the chemical fiber filament is too small.

[0046] The magnetic rod plug 7 is slidably connected at the center of the rotating valve core 31, the rear wall of the sliding block 3 is fixedly connected with a cylinder, the magnetic rod plug 7 and the cylinder are fixedly connected with a connecting spring 71, the magnetic rod plug 7 is internally provided with a magnet, and the magnetic rod plug 7 is magnetically attracted to the moving magnetic plug 61 through the magnet.

[0047] After use, the spooling operator can close the valve of the compressed gas tank 5, so that the magnetic rod plug 7 resets without the pressure of the compressed gas tank 5, and then under the action of the magnetic force of the magnetic rod plug 7, the two moving magnetic plugs 61 are attracted to each other, at this time the upper and lower telescopic pipes 21 are connected with the outside, under the gravity of the sliding block 3 itself and the tension of the elastic rope 8, the sliding block 3 can automatically reset to the center of the slide plate 2, so that after the spooling operator replaces the winding drum 11, the device can control the tension range of the chemical fiber filament again.

[0048] The above merely describes the preferred embodiments of the present application; however, the protection scope of the present application is not limited thereto.
