Description

Technical Field

[0001] This utility model relates to the field of texturing machine technology, specifically a texturing machine for producing high-strength flame-retardant DTY. Background Technology

[0002] A texturing machine is a type of textile machinery that can process untwisted yarns such as polyester and polypropylene into elastic yarns with medium to low elasticity through false twisting. The key process units of a texturing machine include feeding rollers, heating devices, cooling devices, false twisters, oiling mechanisms, and winding mechanisms.

[0003] The prior art utility model patent with publication number CN210048909U discloses a texturing machine for DTY processing, which presses and feeds DTY yarn through the grooves of the first guide pressing wheel and the second guide pressing wheel, and guides the smoke generated during the texturing process through the duct fan.

[0004] However, the oil roller on the first guide wire in the above-mentioned configuration lacks a tension adjustment mechanism, thus failing to regulate the tension of the yarn. This leads to the possibility of yarn breakage when the tension is too high. Furthermore, the filter screen is located directly above the inside of the device, making it easy for impurities to fall off and hindering cleaning. Therefore, we propose a texturing machine for producing high-strength flame-retardant DTY. Utility Model Content

[0005] To address the shortcomings of existing technologies that lack a tension adjustment mechanism, thus hindering the regulation of yarn tension and leading to potential yarn breakage due to excessive tension, and making it inconvenient to clean impurities from the filter screen, this invention provides a texturing machine for producing high-strength flame-retardant DTY. This machine buffers yarn tension, ensuring normal yarn processing, and allows for easy cleaning of the filter screen, preventing impurities from falling and contaminating the yarn. This solves the problems mentioned in the background section.

[0006] The technical solution of this utility model is implemented as follows: A texturing machine for producing high-strength flame-retardant DTY includes a machine body, a heating device connected to the bottom surface of the machine body, a ventilation mechanism connected to the top of the machine body above the heating device, and guide mechanisms symmetrically connected to the inner wall of the machine body. The guide mechanisms are upper pulleys and lower pulleys that are rotatably connected to the machine body. The upper pulleys are located directly above the lower pulleys and the number of the two is equal. The lower pulleys are rotatably connected to one side of a ring frame. The end of the ring frame is rotatably connected to the inside of the machine body. Return springs are connected to the top and bottom of the other side of the ring frame. The other end of the return springs is connected to the inner wall of the machine body. Multiple through holes are opened at the upper and lower ends of the outer wall of the machine body, and the through holes correspond to the positions of the upper pulleys and lower pulleys.

[0007] Optionally, connecting seats are symmetrically connected to the inner wall of the machine along the annular frame, and the connecting seats are rotatably connected to the side wall of the annular frame by adjusting bolts.

[0008] Optionally, connecting rings are fixedly connected to the inner wall of the machine body and the top of the ring frame, and the end of the return spring is connected to the connecting ring at the corresponding position.

[0009] Optionally, the upper pulley is rotatably connected to the U-shaped frame, and the end of the U-shaped frame is connected to an upwardly inclined connecting rod. The top of the connecting rod passes through the mounting hole to the top of the machine body, and the connecting rod is rotatably connected in the mounting hole. The top plate is tightly fixed between the ends of the two connecting rods on the same side.

[0010] A first motor is fixedly attached to the top of the machine body, and a cam is connected to the output end of the first motor. The cam contacts the top of the top plate.

[0011] Optionally, the exhaust mechanism includes a first conical tube connected to the top of the body, an annular support coaxially connected to the upper end of the first conical tube, and multiple air outlets circumferentially opened on the outer wall of the annular support, with a filter screen connected inside the air outlet.

[0012] The top of the annular support is coaxially connected to the upper cover, and a fan located directly above the first conical tube is fastened to the upper cover by a second motor.

[0013] Optionally, the top of the first tapered tube is tightly fitted with an outwardly extending second tapered tube, and the annular support is coaxially connected to the outside of the second tapered tube.

[0014] Optionally, a downward-extending arc-shaped guide surface is provided on the inner top surface of the cover.

[0015] Compared with existing technologies, this invention buffers the tension on the thread through the action of the return spring, connecting seat, and ring frame. Simultaneously, the guiding effect of the fan and the guide surface concentrates impurities inside the ring support. Cleaning is then simple; only the filter screen needs to be removed. This design is not only simple and practical but also convenient for operators, greatly benefiting users. It avoids thread breakage caused by excessive tension and improves the quality of thread processing. Attached Figure Description

[0022] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figures 1 to 4 This utility model provides a technical solution: a texturing machine for producing high-strength flame-retardant DTY, comprising a machine body 10, a heating device 15 connected to the bottom surface of the machine body 10, and guide mechanisms symmetrically connected to the inner wall of the machine body 10. The guide mechanisms are upper pulleys 13 and lower pulleys 19 rotatably connected to the machine body 10. The upper pulleys 13 are located directly above the lower pulleys 19 and the number of the two is equal. The upper pulleys 13 are rotatably connected to a U-shaped frame 14. The end of the U-shaped frame 14 is connected to an upwardly inclined connecting rod 3. The top of the connecting rod 3 passes through a mounting hole 5 to the top of the machine body 10. The connecting rod 3 is rotatably connected in the mounting hole 5. A top plate 8 is fastened between the ends of two connecting rods 3 on the same side. A first motor 6 is fastened to the top of the machine body 10. A cam 11 is connected to the output end of the first motor 6. The cam 11 contacts the top of the top plate 8. Multiple through holes 9 are opened at the upper and lower ends of the outer wall of the machine body 10. The through holes 9 correspond to the positions of the upper pulleys 13 and lower pulleys 19.

[0024] like Figure 2 , 4As shown, the lower pulley 19 is rotatably connected to one side of the ring frame 18, and the end of the ring frame 18 is rotatably connected to the inside of the machine body 10. In order to ensure the stable rotation of the ring frame 18, a connecting seat 17 is symmetrically connected to the inner wall of the machine body 10 along the ring frame 18. The connecting seat 17 and the side wall of the ring frame 18 are rotatably connected by adjusting bolts 25. The tightness of the connection between the ring frame 18 and the connecting seat 17 can be adjusted by adjusting bolts 25, thereby adjusting the buffer tension capacity. The structure is simple and convenient for users to operate.

[0025] like Figure 2 , 4 As shown, in order to achieve rapid tension buffering, return springs 16 are connected to the top and bottom of the other side of the ring frame 18. The other end of the return spring 16 is connected to the inner wall of the machine body 10. Connecting rings 24 are fixedly connected to the inner wall of the machine body 10 and the top of the ring frame 18. The end of the return spring 16 is connected to the connecting ring 24 at the corresponding position. In actual use, the return spring 16 and the lower pulley 19 are staggered to ensure the normal movement of the wire on the lower pulley 19. When the wire moves on the upper pulley 13 and the lower pulley 19, since the return spring 16 is set on both sides of the ring frame 18, it can buffer the tension generated above and below, thus protecting the wire.

[0026] like Figure 2 , 3 As shown, an exhaust mechanism is connected to the top of the body 10 and above the heating device 15. The exhaust mechanism includes a first conical tube 4 connected to the top of the body 10. The upper end of the first conical tube 4 is coaxially connected to an annular support 2. Multiple air outlets 22 are opened circumferentially on the outer wall of the annular support 2. A filter screen 7 is connected inside the air outlet 22. The top of the annular support 2 is coaxially connected to the top cover 1. A fan 20 located directly above the first conical tube 4 is fastened to the top cover 1 by a second motor 12. A second conical tube 21 extending outward is fastened to the top of the first conical tube 4. The annular support 2 is coaxially connected to the outside of the second conical tube 21. A downwardly extending arc-shaped guide surface 23 is provided on the inner top surface of the top cover 1. The arc-shaped guide surface 23 can guide the rising airflow to move into the annular support 2 and be discharged through the air outlet 22.

[0027] In summary, this texturing machine for producing high-strength flame-retardant DTY has a control box on the machine body 10 during use. The control box contains a controller, and a display screen and buttons are connected to the control box. The display screen, buttons, first motor 6, second motor 12, heating device 15, and fan 20 are all connected to the controller. The wire passes through the upper pulley 13 and lower pulley 19. Under the action of the return spring 16, connecting seat 17, and ring frame 18, the tension on the wire can be buffered, avoiding excessive tension that could cause the wire to break, thus improving the quality of wire processing.

[0028] Meanwhile, during processing, the fan 20 draws the air inside the body 10 upwards, and under the guidance of the guide surface 23, it enters the annular support 2 and is discharged through the air outlet 22 on its side wall. Under the action of the filter screen 7 on the air outlet 22, impurities are concentrated inside the annular support 2. When it is necessary to clean the impurities, the filter screen 7 can be removed and the inside of the annular support 2 can be cleaned. This utility model is not only simple in structure and highly practical, but also convenient for workers to operate, bringing great convenience to users.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
