Description

Technical Field

[0001] The utility model relates to the technical field related to air fiber preparation, in particular to an air-cooling shaping mechanism for air yarns of mattress fibers. Background Art

[0002] Mattress fibers generally refer to air fibers. Air fiber elastic materials are made by passing molten polyethylene materials through a mold to obtain fiber filaments, which then fall freely into a water cooling pool to form air fiber sheets. During the free fall, due to the contraction of the space between the molds, the fiber filaments come into contact with each other to form nodes and stick together. The difference between air filaments and air fibers lies in the number of nodes and the bonding strength of the nodes, which determines the lifespan and elastic strength. The number of nodes formed by traditional existing processes is relatively small, and the bonding stability and bonding strength of the nodes are relatively low. In particular, the bonding strength is easily affected by the morphology of the monofilament. If the spinneret of the monofilament is abnormal in a certain period of time and cannot produce the filament normally or the morphology of the produced filament is abnormal, it will cause local defects in the mesh structure, leading to overall quality problems, and not meeting the preparation requirements of air filaments, unless the number of nodes and the bonding strength of the nodes can be guaranteed.

[0003] Therefore, we propose a mattress fiber air-wire air-cooling shaping mechanism to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a mattress fiber air wire air cooling shaping mechanism.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The air-cooling shaping mechanism of mattress fiber air filaments comprises an extrusion device, the extrusion device is provided with a monofilament nozzle, the monofilament nozzle is covered with a hollow annular member, the hollow annular member is fixedly arranged on the extrusion device through a mounting frame, a visual sensor corresponding to the monofilament nozzle is penetrated through the hollow annular member, an air supply fan is fixedly arranged on the extrusion device, an air supply duct is fixedly arranged at the lower air outlet of the air supply fan, the other end of the air supply duct is also fixedly connected and communicated with the hollow annular member, and a plurality of air outlet nozzles corresponding to the monofilament nozzles are fixedly arranged on the hollow annular member.

[0007] Preferably, an annular chamfered surface is provided on the lower side of the inner wall of the hollow annular member, and the plurality of monofilament nozzles are fixedly arranged on the annular chamfered surface and are arranged diffusively and inclinedly.

[0008] Preferably, the air supply duct is tangent to the hollow annular member.

[0009] Preferably, a cylindrical filter is fixedly provided at the air inlet at the upper end of the air supply fan, and the cylindrical filter is fixedly connected to the air supply fan via a threaded structure.

[0010] Preferably, a controller is fixedly mounted on the mounting frame, and the extrusion device, the air supply fan and the visual sensor are all electrically connected to the controller.

[0011] Preferably, the visual sensor adopts a CCD camera, and the visual sensor is covered with a sealed heat-conducting shell.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: the device sets a hollow annular part on the monofilament nozzle, and uses an air supply fan to intermittently convey air into the hollow annular part. The input air is filtered to ensure cleanliness, and the air outlet nozzles arranged in a diffuse shape and tilted are all facing the monofilament nozzle. The intermittent annular air outlet will have an air-cooling and shaping effect on the monofilament. During the shaping process, the monofilament will be affected by the blowing and will intermittently rotate and stretch. When multiple monofilaments are extruded synchronously, more collisions will occur between them, thereby forming more nodes, and the position of the nodes is more firmly fixed. The device sets a visual sensor for the monofilament nozzle. The visual sensor monitors the monofilament nozzle and can detect problems in time. The visual sensor passes through the hollow annular part and can be cooled by the blowing effect, thereby avoiding being affected by temperature and ensuring the service life.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-3 The mattress fiber air wire air cooling shaping mechanism shown comprises:

[0020] The extrusion device 1 plays an extrusion role. The extrusion device 1 is provided with a monofilament nozzle 2 for exporting the monofilament constituting the air filament. In order to realize the air cooling and shaping operation, a hollow ring 3 is provided on the outer shell of the monofilament nozzle 2. The hollow ring 3 is fixedly arranged on the extrusion device 1 through a mounting frame 4. In order to visually monitor the monofilament nozzle 2, a visual sensor 5 corresponding to the monofilament nozzle 2 is penetrated on the hollow ring 3. The visual sensor 5 adopts the existing CCD camera technology. In order to allow the hollow ring 3 to To blow out the gas, an air supply fan 6 is fixedly arranged on the extrusion device 1, and an air supply duct 7 is fixedly arranged on the lower air outlet of the air supply fan 6. The other end of the air supply duct 7 is also fixedly connected and communicated with the hollow annular member 3. A plurality of air outlet nozzles 8 corresponding to the monofilament nozzles 2 are fixedly arranged on the hollow annular member 3. When the air supply fan 6 is working, the plurality of air outlet nozzles 8 can be gradually aimed at the monofilament to blow out the gas, so that the monofilament can be air-cooled and shaped, and the monofilament will rotate and stretch, and adjacent monofilaments will collide to form more nodes, and the nodes are relatively firm.

[0021] In order to ensure the movement of the monofilament, an annular chamfered surface is provided on the lower side of the inner wall of the hollow annular member 3, and a plurality of monofilament nozzles 2 are fixedly arranged on the annular chamfered surface and arranged in a diffuse and inclined manner. At the same time, the air supply duct 7 is tangent to the hollow annular member 3.

[0022] In order to ensure the quality of monofilament molding and avoid contamination, a cylindrical filter 9 is fixedly installed at the air inlet at the upper end of the air supply fan 6. The cylindrical filter 9 is fixedly connected to the air supply fan 6 through a threaded structure. The cylindrical filter 9 adopts existing technology to ensure the cleanliness of the introduced air, and the cylindrical filter 9 can be disassembled, replaced or cleaned.

[0023] In order to achieve intermittent blowing of the monofilament, a controller 10 is fixedly installed on the mounting frame 4. The extrusion device 1, the air supply fan 6 and the visual sensor 5 are all electrically connected to the controller 10. The air supply fan 6 can be controlled to work intermittently, and the extrusion device 1 can also be controlled to work. A signal is sent out after the visual sensor 5 detects a problem.

[0024] In some embodiments, the visual sensor 5 uses a CCD camera, and the visual sensor 5 is covered with a sealed heat-conducting shell. Because the visual sensor 5 passes through the hollow ring part 3, it can be cooled by the internal airflow to ensure the service life.
