Description

Technical Field

[0001] This utility model belongs to the technical field of spinning equipment, specifically relating to a novel cooling blower. Background Technology

[0002] In the spinning process of chemical fiber textiles, uniform cooling of the filament bundle is a crucial step that directly affects the quality and performance of the final fiber. Currently, the industry commonly uses two main types of air-blowing cooling devices: side-blowing devices and ring-blowing devices.

[0003] However, existing technical solutions have a significant limitation: side-blowing and ring-blowing devices are typically configured independently and singly for specific spinning boxes. In other words, a spinning box is usually only equipped with one type of cooling device (either side-blowing or ring-blowing). This fixed configuration has drawbacks: when the same spinning box needs to change the product it produces, the required cooling method often needs to be changed accordingly. However, in existing technologies, the fixed relationship between the cooling device and the spinning box makes this change extremely difficult and inefficient. Changing the cooling method requires a significant amount of time for tedious disassembly, transportation, and reinstallation and debugging, resulting in long production interruptions. When frequently changing specifications, the inefficient changeover process directly reduces equipment utilization and production efficiency, increasing production costs. These difficulties severely limit the factory's production planning, resulting in the spinning box's single function (only able to produce specific specifications of yarn), which in turn narrows the range of product specifications that the entire spinning mill can efficiently produce, making it difficult to flexibly respond to market demands for diversified products.

[0004] Therefore, the above problems urgently need to be solved. Utility Model Content

[0005] Purpose of the utility model: In order to overcome the above shortcomings, this utility model provides a new type of cooling air blowing device that can quickly switch between side blowing cooling mechanism and ring blowing cooling mechanism, improve equipment utilization and production efficiency, and reduce production costs.

[0006] Technical Solution: To achieve the above objectives, this utility model provides a novel cooling air blowing device, including a frame, with a cooling air blowing device slidably connected to the top surface of the frame. A spinning box is located on the top of the cooling air blowing device, and the spinning box is connected to an extruder. A spinning and winding machine is located on the lower side of the frame. The cooling air blowing device includes a side cooling air blowing mechanism and a ring cooling air blowing mechanism, which are separately configured. The side cooling air blowing mechanism and the ring cooling air blowing mechanism can be alternately slid to the working position. This utility model allows for rapid switching between the side cooling air blowing mechanism and the ring cooling air blowing mechanism according to production needs, improving equipment utilization and production efficiency, and reducing production costs.

[0007] Furthermore, in the aforementioned novel cooling air blowing device, the side-blowing cooling mechanism includes a side-blowing box, with an air outlet on the side wall of the side-blowing box. The air outlet is rectangular along the side wall of the side-blowing box, with its long side vertically positioned. An air inlet pipe is provided at the air outlet, including an air inlet and an air outlet. The air outlet and the air outlet are connected together, and the air inlet is connected to the air pipe. The vertically positioned long side of the air outlet covers the entire cooling area of ​​the fiber bundle, ensuring uniform cooling of the fiber bundle.

[0008] Furthermore, in the aforementioned novel cooling blower, the side-blowing cooling mechanism includes an air inlet pipe, an air volume regulating valve, and an air outlet pipe connected in sequence. The air volume regulating valve adjusts the air intake volume. The air outlet pipe has a slot, and a filter plate is connected within the slot. The air outlet pipe is vertically oriented, with one side having an opening that connects to the air outlet, and the side of the air outlet pipe away from the air outlet having a downward-sloping surface. The constricted design of the sloping surface of the air outlet pipe allows for smooth airflow redirection, improving airflow uniformity and thus enhancing the uniformity of fiber bundle cooling.

[0009] Furthermore, in the aforementioned novel cooling blower, the airflow regulating valve includes a valve body, a valve core rotatably connected to the valve body, a worm gear rotatably connected coaxially to the valve core, and a worm meshing with the worm gear, with a handle connected to the worm. The worm and the handle are rotatably connected to the valve body. The handle drives the valve core to rotate via the worm gear and worm, controlling the opening or closing of the airflow regulating valve. Rotating the handle adjusts the valve core angle, achieving stepless adjustment of the airflow speed to adapt to the cooling requirements of different filament specifications and spinning speeds.

[0010] Furthermore, in the aforementioned novel cooling blower, a rectifier mechanism is provided at the air outlet. The rectifier mechanism is a multi-layer mesh and honeycomb panel structure. The rectifier mechanism includes a multi-layer metal mesh and a honeycomb panel. The multi-layer metal mesh consists of 2-4 layers, including an outer layer, a middle layer, and an inner layer. It gradually attenuates the intensity of airflow turbulence, achieving preliminary flow uniformity. Combined with the honeycomb panel, it guides the airflow in a straight line, eliminates residual eddies, reduces wind speed fluctuations, improves airflow uniformity, avoids fiber bundle vibration, and improves molding quality.

[0011] Furthermore, in the aforementioned novel cooling air blowing device, the annular air blowing cooling mechanism includes an annular air blowing bracket, which is slidably connected to a perforated plate. A rectifier cylinder is connected to the lower side of the perforated plate 222. Wire bundles pass through holes in the perforated plate 222 and exit through the rectifier cylinder. A drive mechanism 223 is connected to the annular air blowing bracket 221. A one-way throttle valve 224 is provided at the bottom of the drive mechanism 223. The drive mechanism 223 and the perforated plate 222 are driven together, and the drive mechanism 223 drives the perforated plate 222 to move up and down along the annular air blowing bracket. The drive mechanism 223 is a hydraulic cylinder or a linear cylinder, and the one-way throttle valve 224 is connected to an oil pipe or an air pipe. Other parts of the annular air blowing cooling mechanism are conventionally configured and will not be described in detail here.

[0012] Furthermore, in the aforementioned novel cooling air blowing device, a guide rail is provided on the top surface of the frame, and pulleys are respectively connected to the bottom of the side-blowing cooling mechanism and the ring-blowing cooling mechanism. The pulleys are grouped and located at the four corners of the side-blowing cooling mechanism and the ring-blowing cooling mechanism. The guide rail is made of C-shaped steel, with the guide rail openings facing each other, and the pulleys are slidably connected within the openings of the guide rail. A pin hole is provided at the top of the guide rail, and positioning holes are provided on the bottom surfaces of the side-blowing cooling mechanism and the ring-blowing cooling mechanism, respectively. A positioning pin is simultaneously inserted into both the positioning hole and the positioning pin to lock the side-blowing cooling mechanism or the ring-blowing cooling mechanism onto the guide rail. Limiting blocks are provided at both ends of the guide rail to prevent the side-blowing cooling mechanism and the ring-blowing cooling mechanism from detaching from the guide rail.

[0013] Furthermore, in the aforementioned novel cooling air blowing device, a working platform is provided on the top surface of the frame, and a ladder is provided on one side of the frame. The ladder improves the ease of climbing.

[0014] Furthermore, in the aforementioned novel cooling blower, the side-blowing cooling mechanism has a door on the side away from the air outlet. The door is a double door with a latch that keeps the door closed.

[0015] Depending on the spinning process requirements, select either a side-blowing cooling mechanism or a ring-blowing cooling mechanism. The mechanism slides along the guide rail using pulleys to the working position on the top surface of the frame, and the pulleys are locked to secure the mechanism. Connect the spinning box to the extruder, ensuring that the molten polymer forms filaments through the spinneret of the spinning box, and that the filaments enter the cooling air blowing device vertically.

[0016] If using a side-blowing cooling mechanism: Close the door and lock the latch. Connect the air inlet through the air duct. Rotate the handle to adjust the airflow regulating valve, allowing cooling air to enter the air outlet through the air inlet duct, airflow regulating valve, and air outlet duct. After being evenly distributed by the rectifier mechanism, the air is blown onto the yarn bundle. If using a ring-blowing cooling mechanism: The yarn bundle passes through the holes in the perforated plate, passes through the rectifier cylinder, and is connected to the air pipe by a one-way throttle valve for air delivery, achieving uniform ring-shaped cooling. The cooled yarn bundle then descends to the spinning and winding machine to complete the winding process. If you need to change the cooling method, unlock the pulley, slide the current mechanism away from the working position, slide another mechanism to the working position, and repeat the above steps.

[0017] As can be seen from the above technical solution, this utility model has the following beneficial effects: The novel cooling air blowing device of this utility model can quickly switch between side-blowing cooling mechanism and ring-blowing cooling mechanism according to production needs, improving equipment utilization and production efficiency, and reducing production costs. The rectifier mechanism eliminates residual eddies, reduces wind speed fluctuations, improves airflow uniformity, avoids yarn bundle vibration, and improves forming quality. The air volume regulating valve controls the stepless adjustment of wind speed, adapting to the cooling needs of different yarn bundle specifications and different spinning speeds, improving the flexibility of the device.

[0027] In this embodiment, a working platform 12 is provided on the top surface of the frame 1, and a ladder 13 is provided on one side of the frame 1. The ladder 13 improves the ease of climbing.

[0028] In this embodiment, the side blowing cooling mechanism 21 has a door 24 on the side away from the air outlet 2111. The door 24 is a double door and has a latch to keep the door 24 closed.

[0029] like Figure 2 The novel cooling air blowing device shown includes an air inlet pipe 212 in the side-blowing cooling mechanism 21, comprising an air inlet pipe 2123, an air volume regulating valve 2125, and an air outlet pipe 2124 connected in sequence.

The axis of the air outlet pipe 2124 is vertically arranged, with one side of the air outlet pipe 2124 having an opening that connects to the air outlet 2111, and the side of the air outlet pipe 2124 away from the air outlet 2111 having an inclined surface that slopes downward towards the air outlet 2111.

[0030] In this embodiment, a rectifier mechanism 2126 is provided at the air outlet 2111. The rectifier mechanism 2126 is a multi-layer mesh and honeycomb panel structure. The rectifier mechanism 2126 is detachably connected to the air outlet 2111 for easy disassembly and maintenance. The rectifier mechanism 2126 includes a multi-layer metal mesh and a honeycomb panel. The multi-layer metal mesh has 2-4 layers, including an outer layer, a middle layer, and an inner layer, which gradually attenuates the turbulence intensity of the airflow to achieve preliminary flow uniformity. Combined with the honeycomb panel, it guides the airflow to move in a straight line, eliminates residual eddies, reduces wind speed fluctuations, and improves airflow uniformity.

[0031] In this embodiment, the top surface of the frame 1 is provided with a guide rail 11. The bottom of the side-blowing cooling mechanism 21 and the ring-blowing cooling mechanism 22 are respectively connected to pulleys 23, which are grouped and located at the four corners of the side-blowing cooling mechanism 21 and the ring-blowing cooling mechanism 22. The guide rail 11 is made of C-shaped steel, with its openings facing each other. The diameter of the pulleys 23 matches the opening of the guide rail 11, and the pulleys 23 slide smoothly within the opening of the guide rail 11, ensuring smooth sliding without lateral deviation. The top of the guide rail 11 has a pin hole, and the bottom surfaces of the side-blowing cooling mechanism 21 and the ring-blowing cooling mechanism 22 each have positioning holes. A positioning pin is inserted into both the positioning hole and the positioning pin to lock the side-blowing cooling mechanism 21 or the ring-blowing cooling mechanism 22 onto the guide rail 11. Limiting blocks are provided at both ends of the guide rail 11 to prevent the side-blowing cooling mechanism 21 and the ring-blowing cooling mechanism 22 from detaching from the guide rail 11.

[0032] like Figure 3The novel cooling blower shown features a butterfly valve 2125 with a valve core rotation angle of 0-90°. The airflow regulating valve 2125 includes a valve body 21250, a valve core rotatably connected within the valve body 21250, a worm gear 21251 rotatably connected coaxially to the valve core, and a worm 21252 meshing with the worm gear 21251. A handle 21253 is connected to the worm 21252. The worm 21252 and handle 21253 are rotatably connected to the valve body 21250. The handle 21253 drives the valve core to rotate via the worm gear 21251 and worm 21252, controlling the opening or closing of the airflow regulating valve 2125. A scale is set on the valve body 21250 with an accuracy of ±1°. The number of rotations of the handwheel 21253 corresponds to the valve core angle as follows: 1 rotation = 45°, requiring 2 rotations to fully open or fully close.

[0033] like Figure 4-5 The novel cooling air blowing device shown includes a ring air blowing cooling mechanism 22 comprising a ring air blowing bracket 221. A perforated plate 222 is slidably connected to the ring air blowing bracket 221. A rectifier cylinder is connected to the lower side of the perforated plate 222. Wire bundles pass through holes in the perforated plate 222 and exit through the rectifier cylinder. A drive mechanism 223 is connected to the bottom of the ring air blowing bracket 221. A one-way throttle valve 224 is provided at the bottom end of the drive mechanism 223. The top end of the drive mechanism 223 is driven to connect to the perforated plate 222, and the drive mechanism 223 drives the perforated plate 222 to move up and down along the ring air blowing bracket 221. The perforated plate 222 and the ring air blowing bracket 221 are slidably connected via a slide rail or guide post. The drive mechanism 223 is a hydraulic cylinder or a linear cylinder, and the one-way throttle valve 224 is connected to an oil pipe or an air pipe. Other parts of the ring air blowing cooling mechanism are conventionally configured and will not be described further. The one-way throttle valve 224 is an adjustable one-way throttle valve. The rectifier cylinder is a ring-shaped air-blowing wire mesh cylinder with multiple layers of metal mesh inside and out. The perforated plate 222 is located at the top of the air inlet box. The two ends of the rectifier cylinder are respectively connected to the openings at the top and bottom of the air inlet box. Cold air enters the air inlet box through the air guide pipe and is evenly delivered from the side wall of the ring-shaped air-blowing wire mesh cylinder in a full circumference to cool the wire bundle, reduce wire bundle vibration, reduce the U-value of the wire bundle, and reduce the breakage rate.

[0034] According to the requirements of the spinning process, either the side-blowing cooling mechanism 21 or the ring-blowing cooling mechanism 22 is selected. The mechanism slides along the guide rail 11 to the working position on the top surface of the frame 1 via the pulley 23, and the pulley 23 is locked to fix the mechanism. The spinning box 3 is connected to the extruder to ensure that the molten polymer forms a filament bundle through the spinneret of the spinning box 3, and the filament bundle enters the cooling blowing device 2 vertically.

[0035] If using the side-blowing cooling mechanism 21: Close the door 24 and lock the latch. Connect the air inlet 2121 through the air duct. Rotate the handle 21253 to adjust the air volume regulating valve 2125, so that the cooling air enters the air outlet 2111 through the air inlet duct 2123, the air volume regulating valve 2125, and the air outlet duct 2124. After being evenly distributed by the rectifier mechanism 2126, it is blown onto the yarn bundle. If using the ring-blowing cooling mechanism 22: The yarn bundle passes through the holes of the perforated plate 222, passes through the rectifier cylinder, and is connected to the air pipe by the one-way throttle valve 224 for air supply, achieving uniform ring-shaped cooling.

If it is necessary to change the cooling method, unlock the pulley 23, slide the current mechanism away from the working position, slide another mechanism to the working position, and repeat the above steps.
