Description

Technical Field

[0001] This utility model relates to the field of loom technology, and in particular to a stretching nozzle device for an air-jet loom. Background Technology

[0002] An air-jet loom is a machine that uses high-pressure airflow to interweave weft and warp yarns to form a fabric. It propels the warp and weft yarns together by jetting high-speed airflow, causing them to interweave on the fabric to form cloth. Air-jet looms have advantages such as high production efficiency, high speed, and wide applicability, and are widely used in the textile industry. The stretching nozzle device of an air-jet loom can spray gas by controlling the air pressure and spray direction. This gas can be air, steam, or other suitable gases, which are used to form a thin film on the surface of the fabric, thereby stretching the fabric and making it smoother.

[0003] According to the authorization announcement number CN221645201U, a tension nozzle device for an air-jet loom relates to the field of air-jet loom technology. Its beneficial effects are as follows: Through the action of the protective shell, sliding groove, automatic sliding strip, steering wheel, automatic telescopic rod, air head, and air nozzle, the air head can be automatically lifted when blocked by external factors, facilitating cleaning of the air nozzle without affecting the weaving operation. Then, through the action of the fixing plate and the adhesive cleaning strip, when the air nozzle is blocked, the air nozzle and the adhesive cleaning strip can be engaged, facilitating the cleaning of the blockage inside the air nozzle, ensuring that the weaving operation is not affected and improving work efficiency. Finally, through the action of the fitting groove, the air head performs weaving operations in a fixed position, and when cleaning is required, it can be moved freely out of the fitting groove for easy cleaning.

[0004] While the above technology makes it easy to clean the nozzles, it is difficult to make the fabric smooth by simply spraying hot air onto it during fabric processing. This is because the hot air sprayed from the nozzles only keeps the fabric at a high temperature, and the fabric cannot achieve smoothness on its own in this state. The fabric needs to be shaped to achieve a smooth effect. Utility Model Content

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example 1:

[0029] Reference Figures 1-4 This is the first embodiment of the present utility model. This embodiment provides a stretching nozzle device for an air-jet loom, including a workbench 1, a bracket 2 fixedly connected to one side of the top of the workbench 1, an electric cylinder 3 provided on the top of the bracket 2, an air-jet disc 4 fixedly connected to the top rod of the electric cylinder 3, and a shaping component 9 and a winding frame 10 respectively provided on the other side of the top of the workbench 1.

[0030] The shaping assembly 9 includes a housing 91 fixed to the top of the workbench 1. The inner wall of the housing 91 is rotatably connected to a lower shaping roller 92 via a bearing seat. A mounting seat 93 is provided above the lower shaping roller 92. An upper shaping roller 94 is rotatably connected to the inner wall of the mounting seat 93. A screw 95 is threadedly connected to the inner wall of the housing 91. The bottom end of the screw 95 is rotatably connected to the top of the mounting seat 93 via a bearing seat. Openings are provided on both sides of the housing 91.

[0031] The shaping component 9 also includes a handle 96 fixed to the top of the screw 95.

[0032] The shaping component 9 also includes a positioning block 97 fixed to one side of the mounting base 93. A positioning rod 98 is slidably connected to the inner wall of the positioning block 97. One end of the positioning rod 98 is fixedly connected to the inner wall of the outer shell 91. Through the cooperation of the positioning block 97 and the positioning rod 98, the mounting base 93 can be kept moving stably.

[0033] A heating box 5 is installed on the top of the workbench 1, and a serpentine tube 6 is installed inside the heating box 5. A fan 7 is installed on the top of the support 2, and one end of the serpentine tube 6 is connected to the air intake of the fan 7.

[0034] The air outlet of the fan 7 is connected to a flexible hose 8, one end of which is connected to the top of the jet disc 4.

[0035] The serpentine tube 6 includes a heating wire 601 and a filter screen 602. The heating wire 601 is provided on the outer side of the serpentine tube 6, and the filter screen 602 is snapped onto the inner wall of the serpentine tube 6.

[0036] The fabric is inserted through the opening in the housing 91 and passes between the upper shaping roller 94 and the lower shaping roller 92, then exits through the opening on the other side of the housing 91 and finally rests on the take-up frame 10. Next, the handle 96 is turned to move the screw 95, which in turn moves the mounting base 93, causing the upper shaping roller 94 to compact the fabric. The height of the upper shaping roller 94 can be adjusted to accommodate fabrics of different thicknesses. Then, the fan 7 is started to allow external air to enter the serpentine pipe 6. Dust in the air is filtered through the filter screen 602. After entering the serpentine tube 6, the air source is heated by the heating wire 601. The hot air is drawn in by the fan 7 and delivered to the air jet disc 4 through the hose 8, and then blown onto the fabric. The air jet disc 4 is raised and lowered by the electric cylinder 3, which can adjust the airflow intensity to improve weaving efficiency and quality. By blowing hot air onto the fabric, the chemical fibers of the fabric are rearranged at high temperature, and the fabric is flattened by the upper setting roller 94 and the lower setting roller 92, thereby eliminating wrinkles on the fabric and improving the product quality of the fabric.

[0037] Example 2:

[0038] This is the second embodiment of the present invention, which is based on the previous embodiment.

[0039] Specifically, a motor 11 is provided on one side of the winding frame 10. The output end of the motor 11 is fixedly connected to a limit plate 12. A snap-fit ​​post 13 is fixedly connected to one side of the limit plate 12. A lead screw 14 is threadedly connected to the inner wall of the winding frame 10. A hand crank 15 is fixedly connected to one end of the lead screw 14. A conical block 16 is rotatably connected to the other end of the lead screw 14 through a bearing seat.

[0040] Specifically, a take-up roller 17 is provided between the limiting plate 12 and the conical block 16.

[0041] Specifically, the conical block 16 includes a connecting rod 1601 and a fixing pin 1602. The top of the conical block 16 is fixedly connected to the connecting rod 1601, and one side of the connecting rod 1601 is also fixedly connected to the connecting rod 1602.

[0042] Specifically, one side of the take-up roller 17 is provided with a snap-fit ​​groove 18 that is used in conjunction with the snap-fit ​​post 13, and the other side of the take-up roller 17 is provided with a conical groove 19 and a fixing groove 20 that are used in conjunction with the conical block 16 and the fixing pin 1602, respectively.

[0043] The fabric is wound onto the take-up roller 17, and then the motor 11 is started to drive the take-up roller 17 to rotate, thereby winding the fabric. After winding is completed, the hand crank 15 is turned to make the lead screw 14 drive the conical block 16 to move and disengage from the conical groove 19. When the conical block 16 moves, the connecting rod 1601 can drive the fixing pin 1602 to move and disengage it from the fixing groove 20. Then, the take-up roller 17 is moved towards the conical block 16 so that the locking post 13 disengages from the locking groove 18, and the take-up roller 17 can be removed from the take-up frame 10. The reverse operation can be used to install the take-up roller 17 on the take-up frame 10, which is convenient to operate.

[0044] In use, the fabric is passed between the upper setting roller 94 and the lower setting roller 92. Then, the handle 96 is turned to move the screw 95 and the mounting base 93, thereby pressing the fabric with the upper setting roller 94. The height of the upper setting roller 94 can be adjusted to accommodate fabrics of different thicknesses. Next, the blower 7 is started to allow external air to enter the serpentine tube 6 and heat the air source through the heating wire 601. The hot air is drawn in by the blower 7 and delivered to the air jet disc 4 through the hose 8, and then blown onto the fabric. This causes the chemical fibers of the fabric to rearrange at high temperature, and the upper setting roller 94 and the lower setting roller 92 flatten the fabric at high temperature, eliminating wrinkles and improving the product quality of the fabric.
