Description

Technical Field

[0001] This utility model relates to the field of polyester yarn production technology, and in particular to a polyester yarn steaming device. Background Technology

[0002] In the textile processing industry, steaming of polyester yarn is a key process for improving yarn quality. Currently, the industry commonly uses a steaming kettle to treat polyester yarn. In practice, the yarn cones are inserted onto the metal rods of a rotating yarn frame, and then two sets of yarn frames are pushed into the steaming kettle. The kettle creates a controlled humid and hot environment to achieve the steaming treatment of the polyester yarn. This method effectively eliminates internal stress in the polyester yarn, stabilizes twist, and improves hand feel and dyeing uniformity.

[0003] However, existing yarn steaming methods still have significant drawbacks. From the perspective of equipment structural design, traditional yarn steaming kettles lack a moving mechanism for the yarn rack, meaning that the loading and unloading of the yarn rack relies entirely on manual pushing. Taking a common industrial-grade yarn rack as an example, each set needs to support multiple yarn bobbins with a diameter of 30cm and a height of 50cm, with each bobbin weighing approximately 8kg, and the total weight of the entire yarn rack can exceed 100kg. Pushing the yarn rack requires not only the cooperation of multiple workers but also a significant amount of physical exertion. This inefficient operation mode means that loading and unloading a single yarn rack can take 5-20 minutes, greatly reducing production efficiency and increasing the workload of the operators.

[0004] After the steaming process is completed, the existing closed-loop design of the steaming kettle further exacerbates operational risks. Due to the narrow internal space and lack of mechanical assistance, workers must immediately enter the kettle after steaming to pull out the yarn rack. At this time, the internal temperature of the steaming kettle is usually still maintained at 80-90℃, and the relative humidity is as high as 90% or more. This high-temperature and high-humidity environment not only causes acute health problems such as heatstroke and dehydration for operators, but also poses a high risk of burns from direct contact with the high-temperature equipment or yarn rack. If the yarn rack is pulled out after the steaming kettle cools down, the residual heat of the yarn in the high-temperature environment is difficult to dissipate quickly, increasing the difficulty of subsequent processes and reducing the efficiency of the connection between the steaming process and subsequent dyeing, winding, and other steps. This seriously restricts the continuity and automation level of the entire textile production line. Summary of the Invention

[0035] The present invention will now be described in further detail with reference to the accompanying drawings. Unless otherwise explicitly specified and limited, terms such as “installation,” “connection,” “joining,” and “fixing” should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.

[0036] Example 1:

[0037] In order to change the current situation of manually pushing the yarn rack in and out of the steaming pot 1, reduce the labor intensity of the workers, and reduce the probability of burns caused by workers entering the steaming pot 1, this embodiment provides a new steaming device.

[0038] like Figure 1 , Figure 2 As shown, the yarn steaming device includes a steaming kettle 1, a conveyor belt 2, a support frame 4, and a support mechanism 5.

[0039] The steaming kettle 1 is a piece of equipment already disclosed in the prior art, which includes a kettle shell, a kettle cover and sealing system, a steam generation and introduction system, temperature and pressure sensors, a humidity control device, a PLC control cabinet, safety protection devices, etc.

[0040] The steam generation and introduction system includes a steam generator, steam pipes and distributors; the steam generator can be set to electric heating or external boiler steam to provide high-temperature steam (temperature is usually controlled at 100-140℃); the steam pipes and distributors are pipes made of high-temperature resistant metal, with porous distribution pipes or spiral nozzles inside to ensure that the steam is evenly diffused into the vessel.

[0041] The temperature and pressure sensors include temperature sensors, pressure sensors, etc.

[0042] The humidity control device includes a humidifier and a drainage system. The humidifier can be set as an ultrasonic humidifier or a spray device to help regulate the humidity inside the vessel (the humidity range is usually controlled between 80% and 100% RH). The drainage system is a drain valve installed at the bottom of the vessel to drain condensate and prevent water accumulation from affecting the uniformity of the humid and hot environment.

[0043] Safety protection devices include safety valves, over-temperature alarms, and emergency stop buttons.

[0044] As can be seen from the above, when the steaming kettle 1 is working, it can provide suitable temperature, humidity and pressure conditions for steaming yarn.

[0045] like Figure 1 , Figure 2 As shown, when assembling the device, the conveyor belt 2, support frame 4, and support mechanism 5 are all placed inside the vessel body. The support frame 4 is installed on the vessel body along its length, and two sets of support mechanisms 5 are installed at both ends above the support frame 4. One end of one of the support mechanisms 5 is connected to a motor 11 installed on the outside of the vessel body, allowing the support mechanism 5 to rotate when the motor 11 is operating. Then, the conveyor belt 2 is fitted onto the two sets of support mechanisms 5, allowing the conveyor belt 2 to move while the support mechanisms 5 rotate. Figure 4 As shown, in order to stably support the yarn frame on the conveyor belt 2 and control the yarn frame to enter and exit the vessel body while the conveyor belt 2 rotates, two support plates 3 need to be set in parallel between the two sets of support mechanisms 5. The two support plates 3 are attached to the two edges of the inner side of the conveyor belt 2, so that the upper side wall of the conveyor belt 2 can be stably supported by the support plates 3, thereby stably supporting the yarn frame and providing support for its movement.

[0046] like Figure 3 , Figure 5 As shown, in order to detachably install the support frame 4 into the vessel body, the long sidewall of the support frame 4 is designed with an arc shape, and a slot 41 is provided on the arc-shaped sidewall of the support frame 4. A mounting hole 42 is provided at the end of the support frame 4, and two inclined connecting plates 43 are symmetrically and hingedly installed inside the mounting hole 42. In addition, a retaining post 12 is fixedly installed on the sidewall of the vessel body, and a fixing plate 44 is fixedly installed at the end of the vessel body. When installing the support frame 4, the arc-shaped sidewall of the support frame 4 is fitted against the vessel body, and the retaining post 12 is located within the slot 41. Then, the bottom of the inclined connecting plate 43 is detachably installed onto the fixing plate 44.

[0047] like Figure 6 As shown, in order to ensure that the yarn frame is placed stably relative to the conveyor belt 2, two rings of retaining protrusions 21 are symmetrically arranged on the conveyor belt 2, and the wheels of the yarn frame are located between or outside the two rings of retaining protrusions 21, so that the yarn frame can be placed stably under the action of the retaining protrusions 21.

[0048] like Figure 7 As shown, in order to stably support the conveyor belt 2 by means of the support mechanism 5, the support mechanism 5 includes a support shaft 54 ​​and a support roller 51. The support roller 51 is provided with a through hole 53 in the middle. The support shaft 54 ​​is provided through the through hole 53, and a bearing seat is sleeved on the end of the support shaft 54 ​​that protrudes from the through hole 53. The bearing seat is installed on the support frame 4, so that the support roller 51 can be stably supported under the action of the support shaft 54, and support can be provided for driving the conveyor belt 2 to rotate.

[0049] like Figure 7As shown, to facilitate the disassembly and assembly of the support shaft 54 ​​when the support roller 51 is connected to the motor 11, a mechanical seal is provided at the end of the support shaft 54 ​​connected to the motor 11, penetrating the side wall of the steaming kettle 1 to prevent the presence of the support shaft 54 ​​from affecting the sealing of the kettle body. A snap-fit ​​groove 55 is provided on the support shaft 54, and a snap-fit ​​post is fixedly provided on the inner side wall of the through hole 53. Therefore, when the support shaft 54 ​​is installed through the through hole 53, a relatively static connection between the support shaft 54 ​​and the support roller 51 can be achieved through the cooperation of the snap-fit ​​post and the snap-fit ​​groove 55, allowing the support roller 51 to rotate while the motor 11 controls the rotation of the support shaft 54.

[0050] like Figure 6 , Figure 7 As shown, in order to control the rotation of the conveyor belt 2 while the support roller 51 rotates, multiple meshing teeth 22 are evenly distributed in the middle of the inner sidewall of the conveyor belt 2, and multiple meshing grooves 52 are evenly distributed along the circumference of the sidewall of the support roller 51. During assembly, the meshing teeth 22 are aligned with the meshing grooves 52, and the meshing teeth 22 and the meshing grooves 52 are engaged and connected to achieve a stable connection between the support roller 51 and the conveyor belt 2.

[0051] like Figure 1 , Figure 2 As shown, in order to avoid the presence of the meshing teeth 22 affecting the contact between the support plate 3 and the conveyor belt 2, the length of the meshing teeth 22 is less than the width of the conveyor belt 2, and the two support plates 3 are distributed on both sides of the meshing groove 52.

[0052] like Figure 8 , Figure 9 As shown, in order to reduce the resistance of the conveyor belt 2 moving relative to the support plate 3, a recessed groove 33 is provided on the upper side of the support plate 3, and multiple rollers 32 are evenly distributed in the recessed groove 33, with the rollers 32 distributed along the length of the support plate 3. During installation, the top of the rollers 32 is made slightly higher than the upper side of the support plate 3, so that the rollers 32 can contact the inner wall of the conveyor belt 2. When the conveyor belt 2 is stably supported, the rolling of the rollers 32 can reduce the friction between the conveyor belt 2 and the support plate 3.

[0053] Furthermore, the end of the support plate 3 is designed with an arc-shaped structure, and the support roller 51 is positioned close to the arc-shaped end of the support plate 3 to reduce the gap between the support plate 3 and the support roller 51, thus facilitating the movement of the yarn frame.

[0054] like Figure 10 As shown, in order to stably install the support plate 3 on the support frame 4, multiple insertion rods 34 are fixedly installed on the lower side of the support plate 3. The end of each insertion rod 34 is inserted into the end of the bracket 31, and the bottom of the bracket 31 is connected to the support frame 4 by bolts.

[0055] Example 2:

[0056] like Figure 11 , Figure 12 As shown, based on Embodiment 1, in order to adjust the tension of the conveyor belt 2, an adjustment mechanism 6 is provided above the support frame 4. The adjustment mechanism 6 includes a pressure roller 61 and support devices at both ends of the pressure roller 61. Both sets of support devices are installed on the support frame 4, and the pressure roller 61 is located inside the conveyor belt 2. The length of the pressure roller 61 is less than the width of the conveyor belt 2. With this arrangement, the height of the pressure roller 61 can be adjusted by adjusting the state of the support devices, pressing against the lower sidewall of the conveyor belt 2 to keep it taut, thus ensuring that the conveyor belt 2 is stably positioned relative to the support roller 51.

[0057] Specifically, the support device includes a bearing seat 62, a lifting plate 63 disposed above the bearing seat 62, and a vertical plate 65 located on the side of the lifting plate 63. The bearing seat 62 is sleeved on the end shaft of the pressure roller 61, and the lifting plate 63 is fixedly installed on the bearing seat 62. At the same time, a sliding plate 64 is provided on the side of the lifting plate 63, and a sliding groove 66 is provided on the vertical plate 65. An adjusting screw 67 is provided inside the sliding groove 66. The sliding plate 64 is installed in the sliding groove 66 to control the lifting plate 63 to be stably installed on the side of the vertical plate 65. The adjusting screw 67 is threaded through the sliding plate 64 and can control the lifting plate 63 to rise and fall by rotating the adjusting screw 67, thereby realizing the adjustment of the height of the pressure roller 61.

[0058] The above embodiments based on this utility model serve as inspiration. Through the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. Any modifications, equivalent substitutions, or improvements within the spirit and principles of this solution should be included within the protection scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification but must be determined according to the scope of the claims.
