Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4A dual heating device for a sizing and grading machine includes a heating cylinder 1 and a support frame 2. The heating cylinder 1 has an inlet channel 3 and an outlet channel 4, and an annular hot air cavity 5. The inner wall of the heating cylinder 1 has several air guide holes 6 that communicate with the annular hot air cavity 5. A hot air blower 7 is installed on the support frame 2, and the output end of the hot air blower 7 is connected to the annular hot air cavity 5. A heating roller 8 is coaxially installed inside the heating cylinder 1. The heating roller 8 is used to wind yarn, and an electric heating tube 9 is integrated inside the heating roller 8.

[0025] In this utility model, yarn is fed into the heating cylinder 1 through the inlet channel 3 via the feeding roller assembly, and the yarn is wound around the surface of the heating roller 8. The heating roller 8 is heated by the electric heating tube 9, and the yarn is heated in the first stage by direct conduction.

[0026] Simultaneously, the hot air blower 7 operates, continuously supplying a constant-temperature hot airflow into the annular hot air chamber 8. The hot airflow forms a uniform air curtain through precisely distributed air guide holes 6, providing all-around convective heating to the surface of the yarn. After heating and drying, the yarn is conveyed to the outside of the heating cylinder 1 through the outlet channel 4 and under the action of the winding mechanism. This design significantly improves heat energy utilization through a dual heating mode of conduction and convection, ensuring uniform heating of the yarn. At the same time, the integrated cylinder structure achieves a compact layout and optimizes heat energy management.

[0027] The heating cylinder 1 includes a lower shell 101 and an upper shell 102, which are connected by a hinge to form an openable and closable cylindrical structure. The annular hot air cavity 5 is a semi-annular cavity machined on the inner walls of the lower shell 101 and the upper shell 102 respectively, which forms an annular air cavity when closed. The heating cylinder 1 adopts a split design and is opened and closed by a hinge for easy maintenance.

[0028] like Figure 4 As shown, the outlet end of the hot air blower 7 is connected to a connecting pipe 71, which communicates with the annular hot air cavity 5 of the lower shell 101. A telescopic flexible hose 72 is connected to the connecting pipe 71, which communicates with the annular hot air cavity 5 of the upper shell 102. The design of the telescopic flexible hose 72 ensures that the upper shell 102 can be opened and closed normally and that hot air can be introduced.

[0029] In addition, a rotary motor 10 is fixedly installed on the outside of the lower shell 101, and a heating roller 8 is rotatably connected inside the lower shell 101. The output shaft of the rotary motor 10 is fixedly connected to the heating roller 8. The heating roller 8 is driven to rotate by the rotary motor 10, and its rotation is synchronized with the yarn travel speed, which can effectively reduce friction and protect the yarn quality.

[0030] The surface of the heating roller 8 is provided with spiral grooves 81, with a depth of 0.5-2mm and a pitch of 10-30mm, to increase the contact area of ​​the yarn, thereby improving heat conduction efficiency and accelerating the drying speed. In addition, the groove structure can also guide the yarn to be evenly distributed, avoiding stacking or local overheating.

[0031] Furthermore, a temperature feedback module 11 is installed inside the heating cylinder 1, and a controller 12 is installed on the surface of the heating cylinder 1. The temperature feedback module 11 monitors the surface temperature of the heating roller 8 and the outlet temperature of the annular hot air chamber 5 in real time. The hot air blower 7, the electric heating tube 9, the rotary motor 10, and the temperature feedback module 11 are respectively connected to the controller 12. The temperature feedback module 11 monitors the surface temperature of the roller and the hot air temperature in real time. The controller 12 dynamically adjusts the electric heating tube 9, the hot air blower 7, and the rotary motor 10. Among them, the temperature feedback module 11 can use an infrared sensor (to monitor the surface temperature of the heating roller 8) and a thermocouple (to monitor the hot air temperature) to optimize energy consumption and yarn quality through an intelligent temperature control system.

[0032] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
