Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile processing equipment, and in particular to a heating device for polyester texturing yarn in a texturing machine. Background Technology
[0002] Texturing machines are textile machines that can process untwisted yarns such as polyester and polypropylene into elastic yarns with medium to low elasticity through false twisting. Polyester texturing yarns require heating during the processing.
[0003] When heating polyester textured yarn, conventional heating involves heating the polyester textured yarn and the entire surrounding open area. This is achieved by using a fan to deliver hot air to the polyester textured yarn transmission area and the surrounding external area. However, if the heating area is too large, the preheating time will increase, leading to greater heat waste. Furthermore, a large area of the heating area connected to the outside environment will also increase heat loss. Therefore, a polyester textured yarn heating device for texturing machines is needed to reduce the heating space of the polyester textured yarn and thus reduce heat consumption. Utility Model Content
[0004] The purpose of this utility model is to overcome the defects caused by excessive heating space in conventional heating methods and to provide a heating device for polyester texturing yarn in a texturing machine.
[0005] The technical solution to achieve the above objective is: a heating device for polyester texturing yarn in a texturing machine, comprising a support, a placement groove on one side wall of the support, a placement hole on the side wall of the placement groove, a fan connected to the inner side wall of the placement hole, a closed tube connected to one end of the placement hole, the closed tube being open and closed at the end away from the fan, an electric heating wire connected to the inner side wall of the closed tube, an air supply mechanism provided on the side wall of the closed tube, a recovery mechanism provided on the air supply mechanism, a heating mechanism installed on the air supply mechanism and the recovery mechanism, and an auxiliary mechanism installed on the support.
[0006] By adopting the above technical solution, the polyester textured yarn is placed into the auxiliary mechanism and the heating mechanism. The auxiliary mechanism is used to limit the vertical movement of the polyester textured yarn. The fan and electric heating wire are activated to allow hot air to flow into the air supply mechanism and the heating mechanism to heat the polyester textured yarn. The heating mechanism reduces the heating area of the polyester textured yarn, thereby reducing heat waste. The flowing hot air blows off the floating dust on the surface of the polyester textured yarn, achieving a cleaning effect. The dust is collected by the recycling mechanism. At the same time, some of the hot air is also returned to the air supply mechanism through the recycling mechanism, thereby further reducing heat loss.
[0007] Preferably, the air supply mechanism includes a duct and an air supply pipe, the closed end of the closed pipe is connected to and communicates with the duct, one end of the duct is connected to the other side wall of the support, and one side wall of the duct is connected to and communicates with a plurality of arrayed air supply pipes.
[0008] By adopting the above technical solution, hot air enters through the duct and then flows from the air supply pipe into the heating mechanism, thereby achieving the effect of heat transfer.
[0009] Preferably, the recycling mechanism includes a recycling pipe, a one-way valve, a filter screen, a bottom pipe, and a collection box. The other side wall of the conduit is connected to and communicates with a plurality of arrayed recycling pipes. The inner side wall of the recycling pipe near the conduit is connected to a one-way valve. The inner side wall of the recycling pipe away from the conduit is connected to a filter screen. The bottom pipe is connected to and communicates with the end of the recycling pipe away from the conduit. The bottom end of the bottom pipe is connected to a collection box.
[0010] By adopting the above technical solution, the hot air flowing downwards in the heating mechanism will carry the dust to the bottom pipe. The dust falls into the collection box. The hot air entering the recovery pipe is filtered by the filter screen to prevent dust from entering the recovery pipe. The one-way valve can prevent the hot air in the duct from flowing back into the recovery pipe and into the duct, thereby achieving the effect of recovering part of the heat.
[0011] Preferably, the heating mechanism includes a lower half-box, a lower connecting block, a lower half-hole, a base plate, an upper half-box, an upper half-hole, an upper connecting block, and a top plate. The side walls of adjacent lower half-boxes are connected to the lower connecting block. Lower half-holes are provided at both ends of the lower half-boxes. The side walls of the lower half-boxes on both sides are also connected to the base plate. The side walls of adjacent upper half-boxes are connected to the upper connecting block. Upper half-holes are provided at both ends of the side walls of the upper half-boxes. The lower half-boxes and upper half-boxes have the same structure. The side walls of the upper half-boxes on both sides are also connected to the top plate. The side wall of one of the base plates is connected to the closed end side wall of the closed tube. The side wall of the other base plate is connected to the other side wall of the support. The base plate is connected to the top plate. The top end of the air supply pipe is connected to and communicates with the side wall of the lower half-box. The top end of the bottom pipe is connected to and communicates with the side wall of the lower half-box.
[0012] By adopting the above technical solution, the lower half and the upper half of the box form a complete narrow heating pipe, while the upper half and the lower half of the hole form the outlet. The polyester elastic yarn passes through the outlet and the heating pipe, so that the hot air only needs to heat the heating pipe, thereby reducing the heating range. In addition, the heating pipe is only connected to the outside through the outlet, which also reduces the connection area between the heating pipe and the outside, and can also reduce heat loss. The air supply pipe sends hot air into the heating pipe, and the hot air will flow along the heating pipe, avoiding the hot air from flowing randomly in all directions and increasing heat loss. Some of the hot air flows out from the outlet of the heating pipe, and some of the hot air flows to the bottom pipe to recover some of the heat from the hot air.
[0013] Preferably, the lower half of the box is placed at an angle, and the top of the bottom tube is located below the top of the air supply tube.
[0014] By adopting the above technical solution, hot air can flow downwards along the heating pipe, and the dust blown down by the hot air can slide down the inclined surface of the inner wall of the lower half of the box into the bottom pipe, making it convenient to collect the dust.
[0015] Preferably, the duct, air supply duct, bottom pipe of the recovery duct, collection box, lower half box and upper half box are all fitted with heat insulation pads.
[0016] By adopting the above technical solutions, heat loss can be reduced.
[0017] Preferably, the auxiliary mechanism includes a support rod, a support block, a rotating shaft, and a limiting wheel. Two sets of support rods are connected to the top side wall of the support, and the two sets of support rods are located on the front and rear sides of the lower half box, respectively. A support block is connected to the top of the support rod. A rotating shaft is connected to the side wall of both the support rod and the support block. A limiting wheel is rotatably connected to the side wall of the rotating shaft, and the limiting wheel is matched and aligned with the lower half hole.
[0018] By adopting the above technical solution, the support block is opened through the connector, the polyester textured yarn is placed into the lower limiting wheel, and then the connector is installed back to fix the support block and the support rod, so that the upper and lower limiting wheels can limit the vertical movement of the polyester textured yarn.
[0019] Preferably, both the auxiliary mechanism and the heating mechanism are provided with connecting parts, the connecting parts including through holes, screw holes and screws, the side walls of the top plate and the side walls of the support block are provided with through holes, the top side walls of the bottom plate and the top side walls of the support rod are provided with screw holes, the side walls of the screws pass through the through holes, and the side walls of the screws are threadedly connected to the screw holes.
[0020] By adopting the above technical solution, the through hole and the screw hole are aligned, the screw is passed through the through hole, and the screw is threadedly connected to the screw hole, thereby fixing the support rod and the support block together, as well as the bottom plate and the top plate together.
[0021] The beneficial effects of this utility model are:
[0022] 1) Place the polyester textured yarn into the auxiliary mechanism and the heating mechanism. The auxiliary mechanism is used to limit the vertical movement of the polyester textured yarn. Start the fan and electric heating wire to make hot air flow from the closed tube to the air supply mechanism, and then to the heating mechanism to heat the polyester textured yarn. The heating mechanism utilizes a relatively enclosed space, which reduces the heating area of the polyester textured yarn, thereby reducing heat waste. The flowing hot air will blow off the floating dust on the surface of the polyester textured yarn, achieving a cleaning effect on the polyester textured yarn. At the same time, some of the hot air also flows back to the air supply mechanism through the recycling mechanism, thereby further reducing heat loss.
[0023] 2) The hot air flowing downwards from the heating mechanism carries dust towards the bottom pipe, where it falls into the collection box. The hot air flowing down flows into the recovery pipe. The hot air entering the recovery pipe is filtered by a filter screen to prevent dust from entering the recovery pipe. The hot air passes through a one-way valve, which prevents the hot air in the duct from flowing back into the recovery pipe, thus achieving the effect of recovering some heat.

[0033] The present invention will be further described below with reference to the accompanying drawings.
[0034] Reference Appendix Figure 1-6 A heating device for polyester texturing yarn in a texturing machine includes a support 1. A placement groove 2 is provided on one side wall of the support 1. A placement hole is provided on the side wall of the placement groove 2. A fan 3 is connected to the inner side wall of the placement hole. A sealing tube 5 is connected to one end of the placement hole. The end of the sealing tube 5 away from the fan 3 is open and closed. An electric heating wire 4 is connected to the inner side wall of the sealing tube 5. An air supply mechanism 6 is provided on the side wall of the sealing tube 5. A recovery mechanism 7 is provided on the air supply mechanism 6. A heating mechanism 8 is installed on the air supply mechanism 6 and the recovery mechanism 7. An auxiliary mechanism 9 is installed on the support 1.
[0035] Polyester textured yarn is placed into auxiliary mechanism 9 and heating mechanism 8. Auxiliary mechanism 9 is used to limit the vertical movement of polyester textured yarn. Fan 3 and electric heating wire 4 are activated to make hot air flow from closed pipe 5 to air supply mechanism 6, and then into heating mechanism 8 to heat polyester textured yarn. Heating mechanism 8 reduces the heating area of polyester textured yarn, thereby reducing heat waste. The flowing hot air blows off the floating dust on the surface of polyester textured yarn, achieving a cleaning effect on polyester textured yarn. The dust is collected by recycling mechanism 7. At the same time, some hot air also flows back into air supply mechanism 6 through recycling mechanism 7, thereby further reducing heat loss.
[0036] Reference Appendix Figure 2 The air supply mechanism 6 includes a duct 601 and an air supply pipe 602. The closed end of the closed pipe 5 is connected to and communicates with the duct 601. One end of the duct 601 is connected to the other side wall of the support 1. One side wall of the duct 601 is connected to and communicates with multiple arrayed air supply pipes 602.
[0037] Hot air enters through duct 601 and then flows through air supply duct 602 into heating mechanism 8, achieving the effect of heat transfer.
[0038] Reference Appendix Figure 1-3The recycling mechanism 7 includes a recycling pipe 701, a one-way valve 702, a filter screen 703, a bottom pipe 704, and a collection box 705. The other side wall of the conduit 601 is connected to and communicates with multiple arrayed recycling pipes 701. The inner side wall of the recycling pipe 701 near the conduit 601 is connected to the one-way valve 702. The inner side wall of the recycling pipe 701 away from the conduit 601 is connected to the filter screen 703. The bottom pipe 704 is connected to and communicates with the end of the recycling pipe 701 away from the conduit 601. The bottom end of the bottom pipe 704 is connected to the collection box 705.
[0039] The downward-flowing hot air from the heating mechanism 8 carries dust towards the bottom pipe 704, where it falls into the collection box 705. The hot air flowing down flows into the recovery pipe 701. The hot air entering the recovery pipe 701 is filtered by the filter screen 703 to prevent dust from entering the recovery pipe 701. The hot air passes through the one-way valve 702, which prevents the hot air in the conduit 601 from flowing back into the recovery pipe 701. This achieves the effect of recovering some heat.
[0040] Reference Appendix Figure 1-5 The heating mechanism 8 includes a lower half-box 801, a lower connecting block 802, a lower half-hole 803, a bottom plate 804, an upper half-box 805, an upper half-hole 806, an upper connecting block 807, and a top plate 808. The side walls of adjacent lower half-boxes 801 are connected to the lower connecting block 802. Lower half-holes 803 are provided at both ends of the lower half-box 801. The side walls of the lower half-boxes 801 on both sides are also connected to the bottom plate 804. The side walls of adjacent upper half-boxes 805 are connected to the upper connecting block 807. Upper half-holes 806 are provided at both ends of the side walls of the upper half-box 805. The lower half-box 801... Similar to the upper half-box 805, the side walls of the upper half-box 805 located on both sides are also connected to the top plate 808. The side wall of one bottom plate 804 is connected to the closed end side wall of the closed pipe 5, and the side wall of the other bottom plate 804 is connected to the other side wall of the support 1. The bottom plate 804 is connected to the top plate 808. The top end of the air supply pipe 602 is connected to and communicates with the side wall of the lower half-box 801. The top end of the bottom pipe 704 is connected to and communicates with the side wall of the lower half-box 801. A temperature sensor can be installed in the lower half-box 801 to detect the temperature inside the heating pipe.
[0041] Align and attach the base plate 804 and top plate 808, align and attach the lower half box 801 and upper half box 805, align the upper half hole 806 and lower half hole 803, and use connectors to fix the base plate 804 and top plate 808 together. This makes the lower half box 801 and upper half box 805 form a complete narrow heating pipe, while the upper half hole 806 and lower half hole 803 form an outlet. Polyester elastic yarn passes through the outlet and the heating pipe, so that the hot air only needs to heat the heating pipe, thereby reducing the heating range. In addition, the heating pipe is only connected to the outside through the outlet, which also reduces the connection area between the heating pipe and the outside, and can also reduce heat loss. The air supply pipe 602 sends hot air into the heating pipe. The hot air will flow along the heating pipe, avoiding the hot air flowing randomly in all directions and increasing heat loss. Some hot air flows out from the outlet of the heating pipe, and some hot air flows to the bottom pipe 704 to recover some of the heat from the hot air.
[0042] Reference Appendix Figure 3 The lower half of the box 801 is placed at an angle, and the top of the bottom tube 704 is located below the top of the air supply tube 602.
[0043] This allows hot air to flow downwards along the heating pipe, and the dust blown down by the hot air can slide down the inclined surface of the inner side wall of the lower half box 801 into the bottom pipe 704, making it convenient to collect the dust.
[0044] Reference Appendix Figure 1 The conduit 601, air supply duct 602, recovery duct 701, bottom pipe 704, collection box 705, lower half box 801 and upper half box 805 are all fitted with heat insulation pads.
[0045] Reduce heat loss from duct 601, air supply duct 602, recovery duct 701, bottom duct 704, collection box 705, lower half box 801, and upper half box 805.
[0046] Reference Appendix Figure 1 Appendix Figure 3 and attached Figure 5 The auxiliary mechanism 9 includes a support rod 901, a support block 902, a rotating shaft 903, and a limiting rotating wheel 904. The top side wall of the support 1 is connected to two sets of support rods 901, which are located on the front and rear sides of the lower half box 801, respectively. The top of the support rod 901 is connected to the support block 902. The side walls of the support rod 901 and the side walls of the support block 902 are both connected to the rotating shaft 903. The side wall of the rotating shaft 903 is rotatably connected to the limiting rotating wheel 904, which is matched and aligned with the lower half hole 803.
[0047] By using the connector, the support block 902 is opened, and the polyester textured yarn is placed onto the lower limiting wheel 904. Then, the connector is installed back to fix the support block 902 to the support rod 901, so that the upper and lower limiting wheels 904 can limit the vertical movement of the polyester textured yarn.
[0048] Reference Appendix Figure 4-6 Both the auxiliary mechanism 9 and the heating mechanism 8 are equipped with connecting parts, which include through holes 10, screw holes 11 and screws 12. The side walls of the top plate 808 and the support block 902 are provided with through holes 10.

The side wall of the screw 12 passes through the through hole 10 and is threadedly connected to the screw hole 11.
[0049] Align the through hole 10 with the screw hole 11, and pass the screw 12 through the through hole 10. The screw 12 is then threaded into the screw hole 11, thereby fixing the support rod 901 and the support block 902 together, as well as the base plate 804 and the top plate 808 together.
