Description

Technical Field

[0001] The utility model relates to an adjustable slow cooling device for spinning, belonging to the technical field of spinning. Background Art

[0002] Spinning is also called chemical fiber forming. It is the process of making certain polymer compounds into colloidal solutions or melting them into melts and then pressing them out from the fine holes of the spinneret to form chemical fibers. When the spinning is ejected from the spinneret through the spinning channel, it is necessary to blow and cool the spinning through a side blowing device. However, in actual production, the applicant found that due to the different raw materials, thickness, and specifications of the spinning products, the fluidity of the fibers is often different, which leads to the poor effect of blowing and cooling different spinning products at a fixed position. It is necessary to study and improve this. Utility Model Content

[0003] Based on the above, the utility model provides an adjustable slow cooling device for spinning to overcome the shortcomings of the prior art.

[0004] The technical solution of the utility model is: an adjustable slow cooling device for spinning, comprising a spinneret, a spinning channel arranged below the spinneret, and a windless channel arranged below the spinning channel, a side blowing device is arranged below the windless channel, and the side blowing device comprises:

[0005] A lifting mechanism is arranged on the lower side of the spinning channel;

[0006] A side-blowing bellows is arranged on the lifting mechanism, and a blowing hole is arranged on the side of the side-blowing bellows perpendicularly facing the axial direction of the spinning channel;

[0007] The air source equipment is connected with the side-blowing bellows through a pipeline.

[0008] In one example, the windless channel includes a first shell and a second shell, the top of the first shell is fixed to the bottom of the spinning channel, the second shell is movably connected to the first shell, and one side of the bottom of the second shell is fixed to the side-blowing air box.

[0009] In one example, the lifting mechanism includes a base plate, a hydraulic cylinder and a guide rod. The hydraulic cylinder is vertically arranged on the base plate, the guide rod is arranged on the base plate and located on both sides of the hydraulic cylinder, the side blowing bellows is arranged on the telescopic rod of the hydraulic cylinder, and the two sides of the side blowing bellows are movably connected to the guide rod.

[0010] In one example, the side-blowing bellows is triangular in shape, with its bottom surface and the side surface close to the spinning channel being right-angled sides, and its side surface facing away from the spinning channel being a hypotenuse, and the interface of the pipeline is arranged on the bottom surface.

[0011] In one example, the side wall of the side blowing bellows where the blowing holes are located is in an arc shape with the middle bulging outward, and a plurality of the blowing holes are arranged on the wall surface at intervals from top to bottom.

[0012] In one example, an air regulating plate is provided on the inner top surface of the side-blowing air box directly above the interface, the air regulating plate is connected to the driving motor, and the air regulating plate is in a curved arc shape.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] 1. By combining the side-blowing bellows and the lifting mechanism, the height and position of the side-blowing bellows can be adjusted according to the specific specifications and fluidity of the spinning products. This adjustment can more accurately control the effect of blowing cooling and adapt to different types of spinning products, thereby improving product quality.

[0015] 2. The side-blowing bellows adopts a triangular structure and curved side wall design, so that the blowing holes can evenly distribute the wind force, reducing local overcooling or overheating, and helping to achieve more uniform fiber cooling. At the same time, the blowing device can more naturally adapt to the spinning curve, reducing the disturbance of the equipment to the original spinning curvature.

[0016] 3. The structural design of the air regulating plate and the driving motor enables the operator to adjust the air volume distribution of the blowing holes according to the needs, so that the air volume of each part can be accurately controlled according to actual needs. This structure not only improves the flexibility of operation, but also enables the equipment to better adapt to different production needs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the 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 violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0022] See also Figure 1 and Figure 2 The present embodiment is an adjustable slow cooling device for spinning, comprising a spinneret 1, a spinning channel 2 arranged below the spinneret 1, and a windless channel 3 arranged below the spinning channel 2. A side blowing device is installed below the windless channel 3. The side blowing device comprises a lifting mechanism 4, a side blowing air box 5 and an air source device 6. The lifting mechanism 4 comprises a bottom plate 41, a hydraulic cylinder 42 and a guide rod 43. The bottom plate 41 is installed on the side below the spinning channel 2. The hydraulic cylinder 42 is vertically installed on the bottom plate 41. A plurality of guide rods 43 are vertically installed on the bottom plate 41 and are located on both sides of the hydraulic cylinder 42. The side blowing air box 5 is installed on the bottom plate 41. The side blowing bellows 5 is on the telescopic rod of the hydraulic cylinder 42, and both sides of the side blowing bellows 5 are movably sleeved on the guide rod 43. The side blowing bellows 5 is triangular in shape, and its bottom surface and the side surface close to the spinning channel 2 are both right-angled sides, and the side surface backing against the spinning channel 2 is a hypotenuse. A plurality of blowing holes 51 are provided on the side of the side blowing bellows 5 vertically toward the axial direction of the spinning channel 2. The air source device 6 is connected to the bottom surface interface of the side blowing bellows 5 through a pipeline 7. When working, the vertical position of the side blowing bellows 5 can be adjusted according to the specifications of the spun products, so that the side blowing position can be appropriately adjusted according to the fluidity of different products, thereby improving the quality of the spun products.

[0023] In order to avoid a gap between the windless channel 3 and the side-blowing air, which would expose the spinning to the air, the windless channel 3 includes a first shell 31 and a second shell 32. The top of the first shell is fixed to the bottom of the spinning channel 2, and the second shell 32 is movably connected to the first shell 31. One side of the bottom of the second shell 32 is fixed to the side-blowing air box 5, so that the second shell 32 can move up and down synchronously with the side-blowing air box 5.

[0024] In order to improve the uniformity of air blowing, the side wall of the side blowing bellows 5 where the blowing holes 51 are located is in an arc shape that bulges outward in the middle, and a number of blowing holes 51 are arranged on the wall from top to bottom. Naturally, the spinning below the spinning channel 2 has a certain curvature. Therefore, by setting the blowing holes 51 from top to bottom into corresponding arc shapes, the uniformity of air blowing in the upper and lower parts of the spinning can be achieved to a certain extent, and the side blowing device can minimize the impact on the original spinning curvature.

[0025] In order to ensure the uniformity of air outlet from each blowing hole 51 and facilitate adjustment, an air regulating plate 52 is installed on the inner top surface of the side blowing bellows 5 directly above the interface of the pipe 7. The air regulating plate 52 is rotatably connected to the inner top surface of the side blowing bellows 5. The air regulating plate 52 is connected to a driving motor 53. The driving motor 53 is installed on the outer surface of the side blowing bellows 5. The air regulating plate 52 is in a curved arc shape. The angle of the air regulating plate 52 can be changed by the driving motor 53, thereby realizing the adjustment of the air blown by each blowing hole 51.
