Description

Technical Field

[0001] The utility model relates to the technical field related to air fiber preparation, in particular to a mattress fiber air filament extrusion device. 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. The bonding strength 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. Improvements need to be made to the current intermittent extrusion operation. At the same time, the spinneret of the monofilament needs to be monitored, and timely alarms are issued when problems occur, thereby avoiding major quality problems.

[0003] Therefore, we propose a mattress fiber air filament extrusion device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. 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 filament extrusion device shown comprises:

[0020] As an extrusion piece 1 with a single extrusion structure, when the air filament is extruded and produced, multiple devices need to be set up to perform extrusion operations synchronously. Specifically, two extrusion holes are symmetrically arranged on the upper end surface of the extrusion piece 1, and a Y-shaped extrusion tube 2 is fixedly arranged on the lower side of the extrusion piece 1. The Y-shaped extrusion tube 2 is connected to the two extrusion holes, and an extrusion head 5 is fixedly arranged at the lower end of the Y-shaped extrusion tube 2, so that extrusion operations can be performed from the two extrusion holes;

[0021] Here is the extrusion operation of the monofilament. In order to monitor the extrusion operation of the monofilament and avoid problems, a monitoring probe 6 is provided on one side of the extrusion head 5. The monitoring probe 6 is fixed on the extrusion piece 1 through a fixing piece 7. The monitoring probe 6 uses a CCD camera to ensure problem monitoring through the existing visual monitoring method.

[0022] In order to realize the extrusion operation, specifically, the two extrusion holes are matched with extrusion plungers 3, the upper ends of the two extrusion plungers 3 are coaxially fixedly connected with control rods 4 and the two control rods 4 extend out of the extrusion holes, and the extrusion piece 1 is provided with elastic limit components corresponding to the two control rods 4. The extrusion piece 1 is provided with reciprocating control components corresponding to the two control rods 4, which can synchronously drive the two extrusion plungers 3 to reciprocate, and the reciprocating motion directions of the two extrusion plungers 3 are opposite, thereby realizing uninterrupted continuous extrusion operation.

[0023] In order to ensure that the extrusion plunger 3 can be reset, in some embodiments, the elastic limit assembly includes a fixed plate 8 slidably mounted on the control rod 4, the fixed plate 8 is fixedly connected to the extrusion piece 1, and a limit spring 9 is mounted on the control rod 4. The lower end of the limit spring 9 is fixedly connected to the fixed plate 8, and the upper end of the limit spring 9 is fixedly connected to the upper end of the control rod 4. The limit spring 9 can drive the control rod 4 to move through elastic force, thereby driving the extrusion plunger 3 to reset.

[0024] In order to synchronously control the two extrusion plungers 3, the reciprocating control assembly includes a fixed frame 10 fixedly arranged on the upper side of the extrusion piece 1, and two rotating shafts 11 are horizontally rotatably arranged on the fixed frame 10, and gears 12 are coaxially fixedly sleeved on the two rotating shafts 11, and the two gears 12 are meshed with each other. Two cam members 13 are also fixedly sleeved on the two rotating shafts 11, and the two cam members 13 are symmetrically arranged at the center. Balls 14 are fixedly arranged on the upper ends of the two control rods 4 and the two balls 14 are respectively against the two cam members 13. A driving motor 15 is fixedly arranged on the fixed frame 10, and the output end of the driving motor 15 is coaxially fixedly connected to one of the rotating shafts 11, and the driving motor 15 drives one of the rotating shafts 11 to rotate. Because of the meshing action of the two gears 12, the relative rotation of the two rotating shafts 11 can be realized, so the two cam members 13 can rotate synchronously relative to each other. Because the orientations of the two cam members 13 are symmetrical, the two balls 14 can be forced to drive the control rod 4 to move, thereby driving the extrusion plunger 3 to move.

[0025] In order to facilitate extrusion, the lower end of the extrusion plunger 3 is set to a hemispherical shape, and the bottom of the extrusion hole groove is set to a hemispherical shape matching the extrusion plunger 3.

[0026] In order to introduce the molten raw material into the two extrusion holes, a Y-shaped introduction pipe 16 is fixedly provided on the side wall of the extrusion piece 1, and the Y-shaped introduction pipe 16 is connected to the lower part of the two extrusion holes. Two one-way valves 17 are symmetrically fixedly connected to the Y-shaped extrusion pipe 2 and the Y-shaped introduction pipe 16, which can ensure the smooth introduction of the molten raw material.

[0027] In some embodiments, the fixing member 7 and the fixing frame 10 are both fixedly connected to the extruded member 1 by a bolt structure, so that part of the structural workpiece can be disassembled to facilitate maintenance and replacement.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
