DETAILED DESCRIPTION

[0045] The following will be combined with the accompanying drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, in the following description, specific details such as specific system structures and technologies are proposed for the purpose of explanation rather than limitation, so as to thoroughly understand the embodiments of the utility model. However, it should be clear to those skilled in the art that the utility model can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from hindering the description of the utility model.

[0046] The utility model provides a heating device for producing low-elastic yarn, according to the attached manual Figure 1 To Attachment Figure 5 It can be seen that a heating device for low-elastic yarn production mainly includes the following parts or components: a heating box 10, a cleaning box 20, a cleaning mechanism 30, and an exhaust gas treatment box 40. The connection relationship of each part or component is as follows:

[0047] A first partition 11 horizontally arranged inside the heating box 10 divides the heating box 10 into a first chamber and a second chamber from top to bottom. A through hole 12 connecting the first chamber and the second chamber is arranged on the first partition 11. A feed port 13 and a discharge port 14 are respectively arranged on the front and rear sides of the first chamber, and a plurality of heating plates 15 are arranged in the second chamber; a cleaning box 20 is arranged at the front side of the heating box 10, and two first guide rollers 21 are arranged in parallel above it, and two second guide rollers 22 are arranged in parallel below it; a cleaning mechanism 30 is arranged in the cleaning box 20 between the two second guide rollers 22, and is used for cleaning the low-elastic wire; an exhaust gas treatment box 40 is connected to the top of the first chamber through an air inlet pipe 41, a demister 42 is arranged in the exhaust gas treatment box 40, and an exhaust port 43 is arranged at the top of the exhaust gas treatment box 40, and a drain port 44 is arranged at the bottom.

[0048] During use, the low-elastic yarn will first enter the cleaning box 20 under the action of the first guide roller 21 and the second guide roller 22. The cleaning box 20 contains cleaning liquid. The low-elastic yarn will be wetted by the cleaning liquid, and the impurities on the low-elastic yarn will be cleaned off by the cleaning mechanism 30. After cleaning, the low-elastic yarn can enter the first chamber of the heating box 10 through the feed port 13. The heating plate 15 will heat the air in the second chamber, and the hot air will float upward and then enter the first chamber through the through hole 12. The low-elastic yarn is heated by the hot air to prevent direct baking, which will cause the heating yarn to twist and deform, thereby ensuring the quality of the finished product.

[0049] During the heating process of the low-elastic yarn, the waste gas generated will enter the waste gas treatment box 40 through the air inlet pipe 41, and after the water mist in the waste gas is cleaned by the demister 42, it will be discharged through the exhaust port 43. The water droplets condensed by the demister 42 will drip on the bottom of the waste gas treatment box 40 and be discharged through the drain port 44. The discharged water can be sent to the cleaning box 20, so as to realize the recycling of water resources and reduce waste.

[0050] As an embodiment, according to the attached Figure 3 It can be seen that a plurality of wire separation discs 23 are arranged at intervals on each first guide roller 21 and the second guide roller 22. The plurality of low-elastic yarns can be guided at the same time, and the two adjacent low-elastic yarns can be prevented from getting entangled when the low-elastic yarns are cleaned, thereby reducing the risk of fiber breakage and improving production quality.

[0051] In this embodiment, according to the specification Figure 3It can be seen that the cleaning mechanism 30 includes: two scrubbing plates 31 are arranged between the two second guide rollers 22, and are respectively located on the upper and lower sides of the second guide rollers 22, and a guide rod 32 is horizontally arranged at the first end of each scrubbing plate 31, and the guide rod 32 is slidably connected to and penetrates the cleaning box 20; the scrubbing assembly is arranged on the cleaning box 20, and is used to drive the two scrubbing plates 31 to slide back and forth along the guide rod 32, and the sliding directions of the two scrubbing plates 31 are opposite; two scrubbing brushes 33 are respectively arranged on the opposite side of the two scrubbing plates 31, and are used to scrub the low-elastic threads.

[0052] The scrubbing assembly can drive the two scrubbing plates 31 to slide back and forth in opposite directions along the guide rod 32, so that the scrubbing brushes 33 on the scrubbing plates 31 scrub the low-elastic yarn, which can effectively remove dirt, impurities and stains on the surface of the low-elastic yarn, making the surface of the low-elastic yarn cleaner and tidier.

[0053] In this embodiment, the scrubbing brush 33 is a soft brush or sponge. The soft brush or sponge is relatively soft and can provide gentle scrubbing, which is not easy to damage the fiber structure of the low-elastic yarn, and can effectively clean dirt and impurities. In addition, scrubbing with the soft brush or sponge can reduce the static electricity generated by the low-elastic yarn and reduce the friction between the low-elastic yarns, which is beneficial to the subsequent process.

[0054] In this embodiment, according to the specification Figure 3 and attached Figure 4 It can be seen that the scrubbing assembly includes: a support plate 341 is vertically arranged on the side wall of the cleaning box 20, and a rotating shaft 342 is horizontally arranged thereon; the middle part of the steering rod 343 is connected to the rotating shaft of the rotating shaft 342, and two first sliding grooves 344 are respectively arranged on the steering rod 343 on both sides of the rotating shaft 342; two connecting rods 345 are respectively horizontally arranged on the two guide rods 32, and are perpendicular to the guide rods 32, and the two connecting rods 345 are respectively slidably arranged in the two first sliding grooves 344; the driving member 50 is arranged on the support plate 341, and is connected to one of the guide rods 32, for driving the guide rod 32 to slide back and forth.

[0055] When the driving member 50 drives one of the guide rods 32 to slide back and forth, the corresponding connecting rod 345 drives the steering rod 343 to swing around the rotating shaft 342. The connecting rods 345 of the two guide rods 32 are respectively located on both sides of the rotating shaft 342. Therefore, when one of the connecting rods 345 moves toward the cleaning box 20, the other connecting rod 345 moves away from the cleaning box 20, and then drives the two scrubbing plates 31 to slide in opposite directions through the guide rod 32, so that the scrubbing brush 33 on the scrubbing plate 31 scrubs the low elastic thread, and the structure is simple. In order to avoid motion interference between the connecting rod 345 and the rotating rod 52, when the rotating rod 52 swings, the connecting rod 345 reciprocates in the first slide groove 344 of the rotating rod 52.

[0056] In this embodiment, according to the specification Figure 4 It can be seen that the driving component 50 includes: a first motor 51 is arranged on the support plate 341, and a rotating rod 52 is arranged at its output end; the first end of the driving rod 53 is connected to one of the guide rods 32, and the second end is provided with a second slide groove 54; the sliding rod 55 is arranged at the free end of the rotating rod 52 and is slidably connected to the second slide groove 54.

[0057] When the first motor 51 drives the rotating rod 52 to rotate, the sliding rod 55 at its free end will slide back and forth in the second sliding groove 54 at the second end of the driving rod 53, thereby driving the driving rod 53 to slide back and forth along its length direction, and the guide rod 32 connected to the driving rod 53 will slide back and forth synchronously.

[0058] In this embodiment, according to the specification Figure 5 It can be seen that a water squeezing mechanism 60 is also provided on the cleaning box 20 at the rear side of the first guide roller 21, and the water squeezing mechanism 60 is used to squeeze out excess water in the low-elastic yarn. The water squeezing mechanism 60 includes: a fixed squeezing roller 61 rotatably provided on the cleaning box 20; an adjustment seat 62 provided on the cleaning box 20, on which a first slideway 63 is vertically provided, and a first slider 64 is slidably provided in the first slideway 63; a movable squeezing roller 65 is parallel to the fixed squeezing roller 61 and rotatably provided on the first slider 64; a first screw 66 is vertically and rotatably provided on the first slider 64, and its upper end is threadedly connected to and penetrates the adjustment seat 62.

[0059] After the low-elastic yarn is cleaned, the humidity is relatively high, so a water squeezing mechanism 60 is required to squeeze out excess water in the low-elastic yarn to prevent excessive humidity from affecting the heating effect on the low-elastic yarn. The low-elastic yarn travels between the fixed squeezing roller 61 and the movable squeezing roller 65. At this time, the fixed squeezing roller 61 and the movable squeezing roller 65 will squeeze the low-elastic yarn during the rotation process. The spacing between the fixed squeezing roller 61 and the movable squeezing roller 65 can be adjusted. By rotating the first screw 66, the movable squeezing roller 65 is driven to rise and fall. Low-elastic yarns of different diameters are used, and the application range is wide.
