Description

Technical Field

[0001] The invention belongs to the technical field of yarn steaming, in particular to a yarn steaming machine for a spinning mill. Background Art

[0002] Yarn steaming, also known as twisting or twist setting, is a process that uses hot steam to set the shape of yarn. During the production process, due to repeated force and friction on the yarn, the internal stress is unbalanced, which may cause fiber deformation, fatigue and static electricity. The twisted yarn will produce a huge untwisting torque, which will affect the subsequent production process. The purpose of yarn steaming is to relax the connection between fiber macromolecules under wet and hot conditions and recombine them in a new position to eliminate fiber fatigue and static electricity, stabilize the twist, and prevent the occurrence of small braid kinks in the subsequent process.

[0003] The yarn steaming machine mainly consists of a steaming box and a yarn rack. The yarn rack can accommodate multiple bobbins. When in use, the yarn rack with the bobbins is first pushed into the steaming box for yarn steaming. After the yarn steaming is completed, the yarn rack is pulled out of the steaming box. After the yarn temperature drops, the yarn bobbins are manually unloaded from the yarn rack one by one.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0021] See also Figure 1-Figure 4 , Figure 6 , Figure 7 and Fig. 9 The present embodiment provides a yarn steaming machine for a spinning mill, comprising a yarn frame 1, a steam box 2 and a cover body 3. The steam box 2 is provided with a built-in track 4, and the cover body 3 is provided with a load-bearing plate 5. The lower end of the load-bearing plate 5 is installed with a supporting roller 6. The load-bearing plate 5 is configured to roll on the built-in track 4 through the supporting roller 6. The yarn frame 1 is detachably arranged on the load-bearing plate 5. The yarn frame 1 is used to place bobbins in batches. The yarn frame 1 moves with the load-bearing plate 5 in the steam box 2. When the yarn frame 1 is moved into the steam box 2, the yarn steaming work can be performed. When the yarn frame 1 is located outside the steam box 2, the yarn loading and unloading actions can be performed. The yarn rack 1 includes a support plate 7 and a yarn placement rod 8. A mounting plate 9 is fixedly provided on the support plate 7. The yarn placement rod 8 is rotatably arranged on the mounting plate 9 via a rotating shaft 10. The angle of the yarn placement rod 8 relative to the mounting plate 9 is adjustable via the rotating shaft 10. The yarn placement rod 8 is used to place the bobbin yarn. When the yarn placement rod 8 is adjusted to a vertical downward state, the bobbin yarn can be automatically unloaded, thereby improving the bobbin yarn unloading efficiency. The yarn placing rod 8 is a hollow rod, and a driving cavity 11 is opened in the yarn placing rod 8. A plurality of positioning baffles 12 arranged along the length direction of the yarn placing rod 8 are slidably provided on the side walls of the driving cavity 11. The positioning baffles 12 are used to position and isolate the bobbin yarn placed on the yarn placing rod 8. When multiple groups of bobbin yarns are placed on the yarn placing rod 8, the positioning baffles 12 can prevent the multiple groups of bobbin yarns from sliding and piling up, and reserve sufficient yarn steaming space between two adjacent groups of bobbin yarns to improve the yarn steaming effect. In addition, through the blocking and limiting of the positioning baffles 12, the yarn unloading action can only be realized when the yarn placing rod 8 is adjusted to a vertical downward state and the positioning baffles 12 are retracted to the driving cavity 11 so that the driving cavity 11 does not protrude from the surface of the yarn placing rod 8, so that the bobbin yarn falls at a fixed yarn unloading position, thereby preventing the bobbin yarn from sliding off the yarn placing rod 8 in advance when the angle of the yarn placing rod 8 is not adjusted into place, thereby affecting the accuracy of the yarn unloading position.

[0022] Specifically, see Figure 6 and Figure 7In this embodiment, a guide slot 13 is provided on the side wall of the driving chamber 11, a driving motor 14 is installed in the driving chamber 11, a driving screw 15 is rotatably provided in the driving chamber 11, a driving plate 16 is threadedly connected to the driving screw 15, a guide slide plate 17 is fixedly provided on the driving plate 16, the guide slide plate 17 is engaged and slidably provided in the guide slot 13, under the rotation drive of the driving screw 15 and the guiding action of the guide slot 13, the driving plate 16 moves horizontally in the driving chamber 11, a mounting seat 18 is fixedly provided on the driving plate 16, a driving connecting rod 19 is hingedly provided on the mounting seat 18, and the other end of the driving connecting rod 19 is hingedly connected to the positioning baffle 12, when the driving plate 16 moves, the driving connecting rod 19 applies force to the positioning baffle 12 to push the positioning baffle 12 to slide along the side wall of the driving chamber 11, so that the positioning baffle 12 can be pushed out of the driving chamber 11, or the positioning baffle 12 can be pulled back into the driving chamber 11.

[0023] It is worth noting that in the present embodiment, in order to improve the lateral movement stability of the driving plate 16, two groups of guide grooves 13 are symmetrically provided on the inner wall of the driving cavity 11, and two groups of guide slide plates 17 are symmetrically provided on both sides of the driving plate 16. The two groups of guide slide plates 17 are respectively engaged and slidably provided in the two groups of guide grooves 13; and in order to improve the positioning accuracy of the yarn tube, the positioning baffle 12 is symmetrically arranged on the axis of the yarn placing rod 8, and the driving connecting rod 19 is correspondingly arranged to the positioning baffle 12. When the symmetrically arranged positioning baffles 12 are pushed out of the driving cavity 11 at the same time, they cooperate to limit the position of the yarn tube.

[0024] Specifically, see Figure 3 , Figure 4 and Figure 5 In the present embodiment, the yarn frame 1 also includes a base 20, on which a plurality of support plates 7 are fixedly provided, and mounting plates 9 are symmetrically arranged about the longitudinal center line of the support plates 7, and the rotating shafts 10 located on the same side of the plurality of support plates 7 are connected, and a driving shaft 21 and a transmission shaft 22 are rotatably arranged on one group of support plates 7, and the driving shaft 21 is fixedly connected to the rotating shaft 10, and a first belt pulley is correspondingly fixedly arranged on the driving shaft 21 and the transmission shaft 22, and a group of first synchronous belts 26 are sleeved on the two corresponding groups of first belt pulleys, and under the action of the first synchronous belt 26, the rotating shafts 10 symmetrically arranged on both sides of the support plate 7 are driven synchronously, and the transmission shaft 22 is externally connected to the output shaft of the rotation adjustment motor 23, and the rotating shaft 10 is driven to rotate through the transmission shaft 22 and the driving shaft 21 under the driving action of the rotation adjustment motor 23, thereby realizing the angle adjustment of the yarn placing rod 8.

[0025] Specifically, see Figure 3 , Figure 4 and Figure 5In this embodiment, a plurality of mounting plates 9 are provided along the height direction of the support plate 7, and the transmission shafts 22 corresponding to the plurality of mounting plates 9 are connected by synchronous transmission belts 24. The length of the mounting plates 9 arranged from top to bottom along the height direction of the support plate 7 gradually shortens, and the length of the yarn placing rods 8 corresponding to the mounting plates 9 arranged from top to bottom gradually increases. The length setting of the mounting plates 9 avoids mutual interference of the yarn placing rods 8 arranged on different mounting plates 9 when they are adjusted to a vertical state for unloading the yarn. A unloading groove 25 is provided on the base 20, and the unloading groove 25 is located below the yarn placing rod 8. When the yarn placing rod 8 is adjusted to a vertical state for unloading the yarn, the yarn tube can fall from the unloading groove 25.

[0026] When this embodiment is used, it cooperates with a forklift and a material receiving conveyor belt to move the yarn frame 1 as a whole to the top of the material receiving conveyor belt by a forklift. When the yarn setting rod 8 is adjusted to a vertical state, the bobbin yarn falls from the yarn setting rod 8 to the material receiving conveyor belt.

[0027] Specifically, see Figure 3 In this embodiment, a moving wheel 27 is provided on the lower surface of the base 20, and a pushing handle 28 is provided on the rear side of the upper surface of the base 20. The push handle 28 and the moving wheel 27 cooperate to facilitate the movement of the yarn frame 1.

[0028] Specifically, see Figure 1 In the present embodiment, a material port 29 is provided at one end of the steam box 2, an external track 30 is installed on the outer side of the end of the steam box 2 provided with the material port 29, a pushing frame 31 is connected to the cover body 3, a pushing roller 32 is provided on the pushing frame 31, and the pushing roller 32 is configured to roll on the external track 30. The position of the cover body 3 relative to the steam box 2 is moved by the cooperation of the pushing roller 32 and the external track 30, thereby realizing the position movement of the yarn frame 1 relative to the steam box 2.

[0029] Specifically, see Figure 1 and Figure 2 In the present embodiment, a sealing groove 33 is formed on the side wall of one end of the steam box 2 having a material opening 29, and a sealing protrusion 34 adapted to the sealing groove 33 is formed on the cover body 3. When the cover body 3 is pushed to seal the material opening 29 of the steam box 2, the sealing protrusion 34 is embedded in the sealing groove 33, thereby improving the sealing completeness of the cover body 3 to the material opening 29 of the steam box 2.

[0030] During specific use, the cover body 3 and the steam box 2 can be fixed by a buckle lock to ensure the stability of the cooperation between the cover body 3 and the steam box 2. The buckle lock is a prior art, so it will not be described in detail in this solution.

[0031] Specifically, see Figure 1 , Figure 2 and Figure 8In this embodiment, a fixed cavity 35 is provided in the load-bearing plate 5, and a fixing mechanism is provided in the fixed cavity 35. The fixing mechanism includes a fixed motor 36 and a bidirectional screw 37. The fixed motor 36 is installed on the bottom wall of the fixed cavity 35. The bidirectional screw 37 is rotatably arranged between the two opposite inner walls of the fixed cavity 35. The bidirectional screw 37 is symmetrically provided with two groups. A second belt pulley is correspondingly provided on the middle part of the bidirectional screw 37 and the output shaft of the fixed motor 36. A group of second synchronous belts 38 are sleeved on the two corresponding groups of second belt pulleys. Under the action of the second synchronous belt 38, the fixed motor 36 drives the bidirectional screw 37 to rotate. Both ends of the bidirectional screw 37 are connected by threads. A driving push plate 39 is fixedly provided with a driving slide rod 40, which penetrates and slides on the side wall of the fixed cavity 35, and a fixed push plate 41 is provided at the free end of the fixed slide rod. The longitudinal section of the fixed push plate 41 is an inverted L-shaped setting, and the upper end of the fixed push plate 41 is located on the outside of the base 20 of the yarn frame 1. Under the action of the driving push plate 39, the driving slide rod 40 drives the fixed push plate 41 to move relative to the yarn frame 1 placed on the load-bearing plate 5. When the fixed push plate 41 approaches and is clamped on both sides of the base 20 of the yarn frame 1, the yarn frame 1 can be fixed on the load-bearing plate 5. When the load-bearing plate 5 moves relative to the steam box 2, the stability of the yarn frame 1 is improved.

[0032] Specifically, see Fig. 9 In this embodiment, a water storage tank 42 is provided on the bottom wall of the steam box 2, and an electric heater 43 is provided in the water storage tank 42. A steam pipe 44 is connected between the water storage tank 42 and the side wall of the steam box 2, and steam is transported to the steam box 2 through the steam pipe 44 to steam the bobbin yarn. The steam pipes 44 are symmetrically arranged on both sides of the steam box 2. A water supply pipe 45 and a drainage pipe 46 are provided on the water storage tank 42, and water replenishment and drainage in the water storage tank 42 can be achieved through the water supply pipe 45 and the drainage pipe 46; the steam pipe 44 includes an air inlet pipe 47 and an air outlet pipe 48, and the air inlet pipe 47 is connected to the air outlet pipe 48. 7 is arranged on the upper part of the water storage tank 42, the air outlet pipe 48 penetrates the side wall of the steam box 2 and is arranged in the steam box 2, the air outlet pipe 48 is arranged corresponding to the yarn placing rod 8, and the air outlet pipe 48 is configured to be symmetrically arranged on both sides of the yarn placing rod 8, and a steam hole 49 is opened on the air outlet pipe 48, and the steam hole 49 is arranged toward the yarn placing rod 8. When the bobbin yarn is placed on the yarn placing rod 8, as the yarn frame 1 is pushed into the steam box 2, the steam hole 49 on the air outlet pipe 48 faces the yarn bobbin, and through the arrangement of the air outlet pipes 48 symmetrically on both sides of the yarn placing rod 8, steam is sprayed from both sides of the bobbin yarn at the same time to steam the bobbin yarn, thereby improving the uniformity of yarn steaming.

[0033] The working principle of the yarn steaming machine for a spinning mill provided in this embodiment is as follows: (1) In the initial state, the yarn placing rod 8 is in a horizontal state. The bobbins are installed on the yarn placing rod 8 in sequence. After the installation is completed, the driving motor 14 is started to rotate forward, and the driving motor 14 drives the driving screw 15 to rotate. Under the driving screw 15 driving the driving plate 16 and the coordinated guiding action of the guide slide plate 17 and the guide slide groove 13, the driving plate 16 moves horizontally in the driving cavity 11. When the driving plate 16 moves, the driving connecting rod 19 pushes the positioning baffle 12 to slide along the side wall of the driving cavity 11, and the positioning baffle 12 is pushed out of the driving cavity 11. The positioning baffle 12 separates multiple bobbins placed on one yarn placing rod 8; (2) After the installation of the bobbin is completed, the creel 1 is moved to the position of the steam box 2, and the creel 1 is transferred to the load-bearing plate 5 by a forklift, and the fixed motor 36 is started. Under the transmission action of the second synchronous belt 38, the fixed motor 36 drives the bidirectional screw 37 to rotate, and the bidirectional screw 37 drives the driving push plate 39 to move. The driving push plate 39 drives the fixed push plate 41 to approach the creel 1 from both sides through the driving slide bar 40, and the fixed push plate 41 clamps and fixes the creel 1; (3) Apply force to the push frame 31 to push the roller 32 to roll along the external track 30. At the same time, the supporting roller 6 rolls along the internal track 4. The yarn frame 1 is pushed into the steam box 2 along with the bearing plate 5. After the sealing protrusion 34 is embedded in the sealing groove 33, the buckle lock is locked to complete the sealing of the cover body 3 and the steam box 2. (4) The water in the water storage tank 42 is heated by the electric heater 43, and the water vapor enters the steam box 2 along the steam pipe 44 and is ejected through the steam hole 49, thereby completing the steaming of the bobbin yarn. (5) After the yarn steaming is completed, the buckle lock is opened, and the yarn frame 1 is pulled out of the steam box 2 under the cooperation of the cover body 3 and the load-bearing plate 5. After the yarn on the yarn frame 1 is cooled at room temperature, the yarn frame 1 is transferred from the load-bearing plate 5 to a position where a material receiving conveyor belt is provided with a forklift, and the yarn frame 1 is positioned above the material receiving conveyor belt; the rotation adjustment motor 23 is started, and the multiple sets of rotating shafts 10 are driven to rotate under the action of the synchronous transmission belt 24 and the first synchronous belt 26, and the rotating shaft 10 drives the yarn placing rod 8 to adjust from a horizontal state to a vertical state; (6) Start the drive motor 14 to reverse. Under the driving action of the drive motor 14, the positioning baffle 12 is retracted into the drive chamber 11. The bobbin yarn has no obstruction and slides from the yarn placement rod 8 to a fixed point and falls onto the material receiving conveyor belt. Under the action of the material receiving conveyor belt, the bobbin yarn is transported to the bobbin yarn packaging area, completing the automatic unloading of the bobbin yarn.
