Description

Technical Field

[0001] The utility model relates to a suction device for a heat preservation box of a spinning and setting roller, belonging to the technical field of spinning heat setting process. Background Technique

[0002] In the process of spinning production, the oiled tow needs to enter the heat preservation box for setting treatment. A setting roller is installed in the heat preservation box, and the temperature in the box is generally kept constant at 240°C. After the tow enters the heat preservation box from the wire outlet on one side of the bottom of the hot roller box, it is wound around a pair of heat setting rollers repeatedly in sequence, and finally exits from the wire outlet on the other side of the bottom. During the setting process, the oil on the tow will precipitate onto the setting roller, and oil fume will be generated during this period. Currently, for the oil fume in the heat preservation box, it is mainly sucked through a pipeline arranged on the box body. However, in practice, the applicant found that the existing method has the following problems: the suction is uneven, which is likely to cause poor setting effect due to local high temperature, the suction force is insufficient, and sometimes the oil fume generated at high temperature cannot be discharged in time. Content of the Utility Model

[0003] Based on the above, the utility model provides a suction device for a heat preservation box of a spinning and setting roller to overcome the deficiencies of the prior art.

[0004] The technical solution of the utility model is: a suction device for a heat preservation box of a spinning and setting roller, including:

The upper suction hood and the lower suction hood are respectively arranged at the inner top and inner bottom of the heat preservation box, and the hood openings of the upper suction hood and the lower suction hood are opposite to each other and located on the upper and lower sides of the setting roller. The upper suction hood and the lower suction hood are both connected to the endothermic pipe, and the endothermic pipe is connected to the fan.

[0007] In one example, the endothermic unit further includes a position adjusting mechanism and a guide rod. The guide rod is vertically arranged around the inside of the heat preservation box. The upper suction hood and the lower suction hood are both movably sleeved on the guide rod, and the upper suction hood and the lower suction hood are both installed on the position adjusting mechanism.

[0008] In one example, the position adjusting mechanism includes a bidirectional lead screw, nuts and a driving motor. The bidirectional lead screw is vertically and rotatably installed at the inner middle position on the inside of the heat preservation box. The driving motor is connected to the bidirectional lead screw. Two nuts are respectively installed on the upper and lower parts of the bidirectional lead screw. The upper suction hood and the lower suction hood are respectively fixedly connected to the two nuts.

[0009] In one example, both the upper suction hood and the lower suction hood are in a horn shape.

[0010] Advantages of the present utility model: The upper suction hood and the lower suction hood are used to evenly smoke and cool the shaping roller, improving the suction efficiency and shaping quality; the use of the position adjustment mechanism and the guide rod enables the position of the suction hood to be adjusted according to needs, improving the flexibility and adaptability of the suction device; the horn-shaped suction hood design enhances the suction effect.

[0018] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific implementation manners of the present utility model will be given with reference to the drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific implementations disclosed below.

[0019] Please refer to Figures 1 to 4, in this embodiment, a suction device for a spinning and shaping roller heat preservation box includes a shaping unit and a heat absorption unit. The shaping unit includes a shaping roller 12 and a heat preservation box 11. Two shaping rollers 12 are installed in parallel at intervals in the heat preservation box 11. The heat absorption unit includes an upper suction hood 21, a lower suction hood 22, a heat absorption pipe 23 and a fan. The upper suction hood 21 and the lower suction hood 22 are respectively installed at the inner top and the inner bottom of the heat preservation box 11, and the openings of the upper suction hood 21 and the lower suction hood 22 are opposite to each other and located on the upper and lower sides of the shaping roller 12. The upper suction hood 21 and the lower suction hood 22 are both connected to the heat absorption pipe 23, and the heat absorption pipe 23 is connected to the fan. The upper suction hood 21 and the lower suction hood 22 are both in a horn shape. By arranging the upper suction hood 21 and the lower suction hood 22 in the heat preservation box 11, the shaping roller 12 can be evenly smoked and cooled.

[0020] In order to improve the suction effect, the heat absorption unit further includes a position adjustment mechanism 24 and guide rods 25. Four guide rods 25 are vertically installed around the inner part of the heat preservation box 11. The upper suction hood 21 and the lower suction hood 22 are both movably sleeved on the guide rods 25, and the upper suction hood 21 and the lower suction hood 22 are both installed on the position adjustment mechanism 24. The relative positions of the upper suction hood 21 and the lower suction hood 22, that is, the positions relative to the shaping roller 12, can be adjusted through the position adjustment mechanism 24, and thus the suction effect can be adjusted as needed.

[0021] For the convenience of operation, the position adjustment mechanism 24 includes a bidirectional lead screw 241, nuts 242 and a driving motor 243. The bidirectional lead screw 241 is vertically and rotatably installed at the inner middle position of the heat preservation box 11. The driving motor 243 is installed outside the heat preservation box 11, and its output shaft is connected to the bidirectional lead screw 241. Two nuts 242 are respectively installed at the upper and lower parts of the bidirectional lead screw 241. The upper suction hood 21 and the lower suction hood 22 are respectively fixedly connected to the two nuts 242. By driving the bidirectional lead screw 241 to rotate through the driving motor 243, the relative movement of the two nuts 242 is driven, and the relative movement of the upper suction hood 21 and the lower suction hood 22 is synchronously driven, so as to realize the adjustment of the positions of the upper suction hood 21 and the lower suction hood 22 relative to the shaping roller 12, and finally achieve the purpose of adjusting the suction force.

[0022] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
