Description

Technical Field

[0001] The invention specifically relates to the technical field of nylon filament stretching, and in particular is a nylon filament variable speed and temperature control stretching device. Background Art

[0002] Nylon is a synthetic fiber with good wear resistance, corrosion resistance and high strength. Nylon filaments are widely used in many fields such as textiles and industry. The performance of nylon filaments depends largely on the arrangement and crystallization of its molecular chains. Stretching is a key process step to improve the performance of nylon filaments. Through stretching, the nylon molecular chains can be oriented along the stretching direction, increasing the interaction between the molecular chains, thereby improving the strength and modulus of the filaments.

[0003] At present, when the traditional nylon filament is being stretched, it is impossible to effectively replace the nylon filament shaft. During the operation of the traditional stretching device, after the unwinding shaft is unwound, the unwinding shaft needs to be replaced manually, which makes the working efficiency of the equipment low. In addition, the traditional stretching device stretches the nylon filaments on multiple unwinding shafts at the same time, which will cause interference or knotting of the nylon filaments during the transmission process, and cannot effectively ensure the stretching effect of the equipment on the nylon filaments.

[0004] When nylon filaments are stretched mechanically, only filaments of a certain length can be stretched. Thus, during the stretching process, the continuous transmission of the nylon filaments cannot be effectively guaranteed, which reduces the working efficiency of the stretching device. Summary of the invention

[0005] The object of the present invention is to provide a nylon filament variable speed temperature control stretching device, in which a nylon filament unwinding shaft is placed on a rotating disk, and a plurality of nylon filaments are arranged on the same unwinding shaft, so that the nylon filaments can achieve a continuous conveying effect during the stretching process, and the nylon filaments to be stretched are transmitted to the first comb teeth through the guide shaft to achieve combing of the plurality of filaments, and the combed filaments are evenly heated by the first temperature controller to ensure the efficiency of filament stretching, and the heated filaments are wound around a low-speed rotating wheel and a high-speed rotating wheel, and are continuously heated by the first temperature controller to ensure the efficiency of filament stretching. The same rotation speed is used to achieve the stretching effect on the nylon filament. After the unwinding shaft at the bottom of the rotating disk is unwound, the unwinding wheel that has been unwound is removed through the clamping assembly. When the mechanical clamp is separated from the connecting rod on the rotating disk, the slide drives the slide plate to achieve the engagement of the teeth on the slide plate with the ratchet gear. The ratchet gear drives the second bevel gear to rotate through the connecting rod, and the second bevel gear engages with the first bevel gear, thereby effectively realizing the rotating shaft driving the rotating disk to rotate 90°, realizing the replacement of the unwinding shaft, and effectively improving the work efficiency to solve the problems of the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0012] As a further technical solution of the present invention, the length of the teeth arranged on one side of the slide is the same as the length of the unwinding wheel, and is the same as the distance between the clamping end of the mechanical clamping claw and the end of the unwinding wheel away from the rotating disk; when the slide drives the mechanical clamping claw to move to the end of the unwinding wheel and the slide moves backward at the same time, the teeth on the toothed plate first mesh with the ratchet gear, but the ratchet gear is idle at this time and will not affect the rotation of the rotating disk. When the slide then drives the mechanical clamping claw to move to one side of the rotating disk, the smooth section of the slide board will not affect the rotation of the ratchet gear; the deflection of the rotating disk is effectively avoided;

[0013] As a further technical solution of the present invention, a plurality of notches are provided on the rotating disk; the notches are located between two adjacent unwinding wheels; a baffle is also fixedly installed on the slide plate; the baffle cooperates with the notches provided on the rotating disk; when the rotating disk rotates 90°, the baffle installed on the slide plate moves to the inside of the notches to block the rotating disk, thereby effectively preventing the rotating disk from shaking during the unwinding process of the unwinding shaft;

[0016] As a further technical solution of the present invention, a guide shaft is provided between the first comb teeth and the unwinding wheel at the bottom of the rotating disk; the guide shaft is fixedly mounted on the top of one end of the frame away from the unwinding assembly through a seat bearing;

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1.

[0019] 2. In the present invention, after the unwinding wheel at the bottom of the rotating disk has finished unwinding, the lead screw is driven to rotate by the driving motor, and the lead screw is connected with the slide by the connecting block, so that the slide drives the mechanical clamp along the guide rod to approach the rotating disk, and after the mechanical clamp clamps the unwinding wheel that has finished unwinding, the driving motor is reversed to realize the mechanical clamp moving to the end away from the rotating disk;

[0020] 3. In the present invention, when the driving motor drives the lead screw to realize the movement of the slide toward one end close to the rotating disk, the slide simultaneously drives the slide plate in the C-shaped frame to move. When the slide plate moves backward, the teeth on the slide plate and the ratchet gear, and the ratchet gear at this time rotates idly. When the unwinding wheel moved by the mechanical clamp is away from the end of one end of the rotating disk, the teeth separate from the ratchet gear, and the mechanical clamp continues to move forward to clamp the unwinding wheel. At this time, the moving distance of the slide plate is the same as the length of the unwinding wheel.

[0021] 4. In the present invention, after the mechanical clamp clamps the unwinding wheel, the slide drives the mechanical clamp to move backward. At this time, the smooth section on the slide plate passes through the ratchet gear.

When the mechanical clamp moves into place, the teeth cooperate with the ratchet gear, the connecting rod, the second bevel gear and the first bevel gear to realize that the rotating shaft drives the rotating disk to rotate 90°, so that the unwinding wheel adjacent to the unwinding wheel that has completed unwinding is rotated to the bottom position of the rotating disk, so as to realize the replacement of the unwinding wheel.

[0022] 5. The present invention; when the slide plate moves forward, the baffle plate fixedly mounted on the slide plate is separated from the notch provided on the rotating disk, which effectively avoids obstruction caused by the rotating shaft driving the rotating disk to rotate. After the rotating disk completes a 90° rotation through the cooperation of the first bevel gear and the second bevel gear, the baffle plate on the slide plate is located in the notch provided on the rotating disk, which effectively avoids the rotating disk from rotating during the unwinding process and effectively ensures the stability of the unwinding.

[0040] See also Figure 1-10 In an embodiment of the present invention, a nylon filament variable speed temperature control stretching device comprises a frame body 1; a rectangular groove is provided on one side of the top frame of the frame body 1, and two symmetrical vertical plates 22 are fixedly installed in the frame; mounting seats 23 are fixedly installed at both ends of the fixed plate on the top of the vertical plate 22; a rotating shaft 24 is movably installed inside the mounting seat 23; one end of the rotating shaft 24 extends to the outside of the frame and is fixedly installed with a rotating disk 20; a plurality of support rods are fixedly installed on the rotating disk 20, wherein the angle between two adjacent support rods is 90 degrees; an unwinding wheel 21 is installed on the support rod;

[0041] A first bevel gear 25 is fixedly mounted on the rotating shaft 24 between the two mounting seats 23; the first bevel gear 25 is meshedly connected with the second bevel gear 100 in the linkage assembly 10; the first bevel gear 25 and the second bevel gear 100 are vertically arranged; the second bevel gear 100 is fixedly mounted on a connecting rod 105; the connecting rod 105 is movably mounted on a fixed plate at the top of the vertical plate 22 through a bearing;

[0042] The end of the connecting rod 105 away from the second bevel gear 100 is matched with a ratchet gear 101; a C-frame 102 is fixedly installed on one side of the ratchet gear 101; a slide plate 103 is movably installed between the C-frame 102 and the ratchet gear 101; and teeth 106 are provided on the side of the slide plate 103 close to the ratchet gear 101.

[0043] By adopting the above technical solution, when in use, the unwinding wheel 21 wound with nylon filaments is placed on the support rod on the rotating disk 20, and the filaments on the unwinding wheel 21 at the bottom of the rotating disk 20 are transmitted to the first combing teeth 4 through the guide shaft 11 to realize combing of the nylon filaments and avoid interference between the nylon filaments. The combed nylon filaments are pulled to the first temperature controller 5 at the bottom of the first combing teeth 4 to realize uniform heating of the nylon filaments, and the heated nylon filaments are wound on the low-speed rotating wheel 6 and the high-speed rotating wheel 7 to ensure the quality and efficiency of the nylon filaments during the stretching process. The stretched nylon filaments are then transmitted to the second temperature controller 9 through the second combing teeth 8 to ensure the quality of the stretched nylon filaments.

[0044] See also Figure 5-7 One end of the slide plate 103 is fixedly mounted on the slide 32 in the clamping assembly 3; the clamping assembly 3 also includes a cross plate 31 fixedly mounted on the frame body 1; guide rods 35 are mounted on both sides of the top of the cross plate 31 through seat bearings; a screw rod 34 is mounted between the two guide rods 35; both ends of the screw rod 34 are mounted on the cross plate 31 through seat bearings;

[0045] In this embodiment, the bottom of both ends of the slide 32 are slidably mounted on two guide rods 35; the bottom of the slide 32 is also threadedly connected to the screw rod 34 through a connecting block; one end of the screw rod 34 is fixedly mounted to the drive motor 33; the top of the slide 32 is fixedly mounted with a mechanical gripper 30;

[0046] The length of the teeth 106 provided on one side of the slide plate 103 is the same as the length of the unwinding wheel 21, and the distance between the clamping end of the mechanical clamp 30 and the end of the unwinding wheel 21 away from the rotating disk 20 is the same;

[0047] By adopting the above technical solution, after the unwinding wheel 21 at the bottom of the rotating disk 20 completes unwinding, the lead screw 34 is driven to rotate by the driving motor 33, and the lead screw 34 is connected with the slide 32 through the connecting block, so that the slide 32 drives the mechanical clamp 30 along the guide rod 35 to approach the rotating disk 20. After the mechanical clamp 30 clamps the unwinding wheel 21 that has completed unwinding, the driving motor 33 is reversed to realize that the mechanical clamp 30 moves to the end away from the rotating disk 20;

[0048] Furthermore, when the driving motor 33 drives the lead screw 34 to realize the movement of the slide 32 toward one end close to the rotating disk 20, the slide 32 simultaneously drives the slide plate 103 in the C-shaped frame 102 to move. When the slide plate 103 moves backward, the teeth 106 on the slide plate 103 and the ratchet gear 101, and the ratchet gear 101 is idle at this time. When the unwinding wheel 21 moved by the mechanical clamp 30 is away from the end of one end of the rotating disk 20, the teeth 106 separate from the ratchet gear 101, and the mechanical clamp 30 continues to move forward to clamp the unwinding wheel 21. At this time, the distance moved by the slide plate 103 is the same as the length of the unwinding wheel 21.

[0049] See also Figure 1-11 In this embodiment, a plurality of notches 200 are provided on the rotating disk 20; the notches 200 are located between two adjacent unwinding wheels 21; a baffle 104 is also fixedly mounted on the slide plate 103; the baffle 104 cooperates with the notches 200 provided on the rotating disk 20;

[0050] A first comb tooth 4 is fixedly mounted on the side wall of the frame body 1 away from the clamping assembly 3; a first thermostat 5 is fixedly mounted on the bottom of the first comb tooth 4; a low-speed rotating wheel 6 is mounted obliquely below the first thermostat 5; the rotating shaft of the low-speed rotating wheel 6 is fixedly mounted on the motor;

[0051] By adopting the above technical solution, after the mechanical clamp 30 clamps the unwinding wheel 21, the slide 32 drives the mechanical clamp 30 to move backward. At this time, the smooth section on the slide plate 103 passes through the ratchet gear 101. When the end of the mechanical clamp 30 moves to the end of the support rod away from the rotating disk 20, the teeth 106 on the slide plate 103 are engaged with the ratchet gear 101, so that the ratchet gear 101 drives the second bevel gear 100 to rotate through the connecting rod 105, and the second bevel gear 100 is engaged with the first bevel gear 25 on the rotating shaft 24, so that the first bevel gear 25 drives the rotating shaft 24 actively. When the mechanical clamp 30 moves into place, the teeth 106 cooperate with the ratchet gear 101, the connecting rod 105, the second bevel gear 100 and the first bevel gear 25, so that the rotating shaft 24 drives the rotating disk 20 to rotate 90°, so that the unwinding wheel 21 adjacent to the unwinding wheel 21 that has been unwound is rotated to the bottom position of the rotating disk 20, so as to replace the unwinding wheel 21;

[0052] See also Figure 1-8 In this embodiment, a high-speed rotating wheel 7 is fixedly mounted on the side wall of the frame body 1; the high-speed rotating wheel 7 is located obliquely above the low-speed rotating wheel 6; a second comb tooth 8 is fixedly mounted on one side of the mounting shell of the high-speed rotating wheel 7 through a connecting plate; a second thermostat 9 is fixedly mounted on the bottom of the second comb tooth 8; a groove for nylon filaments to pass through is provided on the first thermostat 5 and the second thermostat 9;

[0053] A guide shaft 11 is provided between the first comb teeth 4 and the unwinding wheel 21 at the bottom of the rotating disk 20; the guide shaft 11 is fixedly mounted on the top of one end of the frame body 1 away from the unwinding assembly 2 through a seat bearing;

[0054] By adopting the above technical solution, when the slide plate 103 moves forward, the baffle 104 fixedly installed on the slide plate 103 is separated from the notch 200 provided on the rotating disk 20, which effectively avoids the situation that the rotating shaft 24 drives the rotating disk 20 to rotate and causes obstruction. After the rotating disk 20 completes the 90° rotation through the cooperation of the first bevel gear 25 and the second bevel gear 100, the baffle 104 on the slide plate 103 is located in the notch 200 provided on the rotating disk 20, which effectively avoids the situation that the rotating disk 20 rotates during the unwinding process of the unwinding wheel 21, and effectively ensures the stability of the unwinding.

[0055] The working principle of the present invention is as follows: when in use, the unwinding wheel 21 wound with nylon filaments is placed on the support rod on the rotating disk 20, and the filaments on the unwinding wheel 21 at the bottom of the rotating disk 20 are transmitted to the first combing teeth 4 through the guide shaft 11 to realize combing of the nylon filaments and avoid interference between the nylon filaments. The combed nylon filaments are pulled to the first temperature controller 5 at the bottom of the first combing teeth 4 to realize uniform heating of the nylon filaments. The heated nylon filaments are wound on the low-speed rotating wheel 6 and the high-speed rotating wheel 7 to ensure the quality and efficiency of the nylon filaments during the stretching process. The stretched nylon filaments are then transmitted to the second temperature controller 9 through the second combing teeth 8 to ensure the quality of the stretched nylon filaments.

[0056] After the unwinding wheel 21 at the bottom of the rotating disk 20 has completed unwinding, the lead screw 34 is driven to rotate by the driving motor 33, and the lead screw 34 is connected to the slide 32 through the connecting block, so that the slide 32 drives the mechanical clamp 30 along the guide rod 35 to approach the rotating disk 20. After the mechanical clamp 30 clamps the unwinding wheel 21 that has completed unwinding, the driving motor 33 is reversed to realize the mechanical clamp 30 to move to the end away from the rotating disk 20; the unwinding wheel 21 and the support rod are separated by the reversal of the driving motor 33. At the same time, the rotating shaft 24 drives the rotating disk 20 to rotate 90° through the cooperation between the two bevel gears, and the new unwinding shaft 21 is rotated to the unwinding position, so that the continuous operation of the equipment is realized and the production efficiency is improved;

[0057] When the driving motor 33 drives the lead screw 34 to realize the movement of the slide 32 toward one end close to the rotating disk 20, the slide 32 simultaneously drives the slide plate 103 in the C-shaped frame 102 to move. When the slide plate 103 moves backward, the teeth 106 on the slide plate 103 engage with the ratchet gear 101. At this time, the ratchet gear 101 idles. When the unwinding wheel 21 moved by the mechanical clamp 30 is away from the end of one end of the rotating disk 20, the teeth 106 separate from the ratchet gear 101, and the mechanical clamp 30 continues to move forward to achieve complete clamping of the unwinding wheel 21. At this time, the moving distance of the slide plate 103 is the same as the length of the unwinding wheel 21. This effectively avoids the situation where the teeth 106 mesh with the ratchet gear 101 when the slide 32 drives the slide plate 103 to move backward.

[0058] After the mechanical clamp 30 clamps the unwinding wheel 21, the slide 32 drives the mechanical clamp 30 to move backward. At this time, the smooth section on the slide plate 103 passes through the ratchet gear 101. When the end of the mechanical clamp 30 moves to the end of the support rod away from the rotating disk 20, the teeth 106 on the slide plate 103 begin to mesh with the ratchet gear 101, so that the ratchet gear 101 drives the second bevel gear 100 to rotate through the connecting rod 105, and the second bevel gear 100 meshes with the first bevel gear 25 on the rotating shaft 24, so that the first bevel gear 25 drives the rotating shaft 24 actively. When the mechanical clamp 30 moves into place, the teeth 106 cooperate with the ratchet gear 101, the connecting rod 105, the second bevel gear 100 and the first bevel gear 25 to realize that the rotating shaft 24 drives the rotating disk 20 to rotate 90°, so that the unwinding wheel 21 adjacent to the unwinding wheel 21 that has been unwound is rotated to the bottom position of the rotating disk 20, and the unwinding wheel 21 is replaced;

[0059] When the slide plate 103 moves forward, the baffle 104 fixedly installed on the slide plate 103 is separated from the notch 200 opened on the rotating disk 20, which effectively avoids obstruction when the rotating shaft 24 drives the rotating disk 20 to rotate. After the rotating disk 20 completes a 90° rotation through the cooperation of the first bevel gear 25 and the second bevel gear 100, the baffle 104 on the slide plate 103 is located in the notch 200 opened on the rotating disk 20, which effectively avoids the rotating disk 20 from rotating during the unwinding process of the unwinding wheel 21, thereby effectively ensuring the stability of the unwinding.
