Description

Technical Field

[0001] This invention relates to the field of textile processing technology, and in particular to a double-head meltblown machine for clothing and home textiles. Background Technology

[0002] A double-head meltblown machine is a type of textile machinery with two meltblown die assemblies, commonly used in the production and processing of meltblown nonwoven fabrics. Unlike the single-die meltblown machines commonly used in meltblown nonwoven fabric processing, the double-die machine, with its two dies, allows for different height settings, resulting in varying receiving heights on the mandrel. This enables the production of filter elements with a gradually tapering structure—a loose outer layer and a dense inner layer.

[0003] When using a dual-head meltblown machine to produce filter cartridges, the meltblown fabric is received and wound on the mandrel, making it inconvenient to remove it from the mandrel. Therefore, after each production cycle, the mandrel needs to be removed and replaced with a new one. This cumbersome operation reduces the production efficiency of filter cartridges and requires a large number of mandrels, increasing costs. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as: in the process of filter element production using a double-head meltblown machine, since the meltblown cloth is received and wound on the mandrel, it is inconvenient to remove it from the mandrel. Therefore, after each production process, the mandrel needs to be removed and replaced with a new one, which is cumbersome, reduces the production efficiency of filter elements, and requires a large number of mandrels, increasing costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A double-head meltblown fabrication machine for garments and home textiles includes a base, on which a fixed plate and a movable plate are respectively provided. Both the fixed plate and the movable plate have mounting holes. A first rotating shaft is rotatably connected to the mounting hole on the fixed plate, and a second rotating shaft is rotatably connected to the mounting hole on the movable plate. Adjustable mandrels are provided on both the first and second rotating shafts. Two limiting rings are fixedly connected to both the first and second rotating shafts. Telescopic adjustment devices are provided on both the fixed plate and the movable plate. A driving device is provided on the fixed plate, and a material picking device is provided on the base.

[0007] Preferably, the adjustable mandrel includes a regular polygonal rod, which is fixedly connected to one end of a first rotating shaft and a second rotating shaft. Multiple limiting plates are symmetrically fixedly connected to the regular polygonal rod, each limiting plate having a limiting groove. A top plate is slidably connected within each limiting groove, and a first curved surface combination plate is fixedly connected to the top plate. Multiple limiting tubes are symmetrically fixedly connected to the regular polygonal rod, each limiting tube having a sliding groove. A top rod is slidably connected within each sliding groove, and a second curved surface combination plate is fixedly connected to the top rod. The curved sidewalls of the first and second curved surface combination plates have the same curvature, and their sides are wedge-shaped. The two sides of the second curved surface combination plate are parallel, and the two sides of the first curved surface combination plate are outwardly flared from top to bottom.

[0008] Preferably, a triangular slot is provided on the side wall of the regular polygonal rod on the first rotating shaft away from the first rotating shaft, and a triangular block is fixedly connected to the side wall of the regular polygonal rod on the second rotating shaft away from the second rotating shaft.

[0009] Preferably, the telescopic adjustment device includes an air box, which is fixedly connected to one side wall of the fixed plate and the movable plate. The air box is positioned directly opposite the mounting hole, and an empty slot is provided inside the air box. One end of the first rotating shaft and the second rotating shaft are both rotatably connected to the empty slot inside the air box.

[0010] Preferably, each of the first and second rotating shafts has a connecting groove on one side wall that communicates with the mounting hole, and the connecting groove is bent.

[0011] Preferably, the driving device includes a drive motor, which is fixedly connected to one side wall of the fixed plate. A drive shaft penetrating the fixed plate is fixedly connected to the output end of the drive motor. Transmission wheels are fixedly connected to both the first rotating shaft and the drive shaft. The two transmission wheels are driven by a transmission belt. A first one-way bearing is installed between the drive shaft and the transmission wheels.

[0012] Preferably, the material handling device includes a first side plate and a second side plate, both of which are fixedly connected to the base. The drive shaft is rotatably connected to the first side plate. Both the first and second side plates are provided with a transition groove, and a reciprocating screw is rotatably connected in the transition groove. A slide is provided on the reciprocating screw, and the slide is fixedly connected to the moving plate. Gears are fixedly connected to both the drive shaft and the reciprocating screw, and the two gears are meshed together. A second one-way bearing is installed between the drive shaft and the gear.

[0013] The beneficial effects of this invention are:

[0014] An adjustable mandrel is used to receive and wind meltblown fabric. Since the adjustable mandrel can be adjusted to a contracted or unfolded state, after the meltblown fabric production is completed, the mandrel can be adjusted to a contracted state to separate the meltblown fabric from the cylinder wall. Then, the drive motor is controlled to reverse, moving the moving plate away from the fixed plate and separating the adjustable mandrel in the middle so that the operator can take out the meltblown fabric. Because the mandrel does not need to be replaced frequently and the meltblown fabric is easy to pick up and operate, the processing and production efficiency can be significantly improved.

[0015] The drive motor, through the cooperation of the drive shaft with the first and second one-way bearings, can rotate the adjustable spindle and move the moving plate by reversing the direction of rotation. Only one drive motor is needed to complete both operations, saving costs.

[0016] The adjustable mandrel is pneumatically adjusted by switching between expansion and contraction states through positive and negative pressure. It is simple to operate and easy to adjust. High-pressure air can also be introduced into the connecting groove through a conduit to counteract part of the gravity of the first and second rotating shafts, thereby reducing friction and noise. The high-speed flow of high-pressure air from the gap also helps to cool down the rotating connection. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Reference Figure 1-10 A double-head meltblown machine for clothing and home textiles includes a base 1, on which a fixed plate 2 and a movable plate 3 are respectively provided. The fixed plate 2 is fixedly connected to the base 1, and the movable plate 3 is slidably connected to the base 1. Both the fixed plate 2 and the movable plate 3 are provided with mounting holes. A first rotating shaft 4 is rotatably connected in the mounting hole on the fixed plate 2, and a second rotating shaft 5 is rotatably connected in the mounting hole on the movable plate 3. Both the first rotating shaft 4 and the second rotating shaft 5 are provided with adjustable mandrels 6. The adjustable mandrel 6 includes a regular polygonal rod 7, which is fixedly connected to one end of the first rotating shaft 4 and the second rotating shaft 5.

[0030] Multiple limiting plates 8 are symmetrically fixedly connected to the regular polygonal rod 7. Each limiting plate 8 has a limiting groove 9. A top plate 10 is slidably connected to the limiting groove 9. A first curved surface combination plate 11 is fixedly connected to the top plate 10. Multiple limiting tubes 12 are symmetrically fixedly connected to the regular polygonal rod 7. Each limiting tube 12 has a sliding groove 13. A top rod 14 is slidably connected to the sliding groove 13. A second curved surface combination plate 15 is fixedly connected to the top rod 14. The curvature of the curved sidewalls of the first curved surface combination plate 11 and the second curved surface combination plate 15 is the same. The sides of the first curved surface combination plate 11 and the second curved surface combination plate 15 are wedge-shaped. The two sides of the second curved surface combination plate 15 are arranged in parallel. The two sides of the first curved surface combination plate 11 are arranged in an outward expansion manner from top to bottom.

[0031] A triangular slot is provided on the side wall of the regular polygonal rod 7 on the first rotating shaft 4 away from the first rotating shaft 4. A triangular block is fixedly connected to the side wall of the regular polygonal rod 7 on the second rotating shaft 5 away from the second rotating shaft 5. Two limiting rings 16 are fixedly connected to both the first rotating shaft 4 and the second rotating shaft 5. Both the fixed plate 2 and the movable plate 3 are provided with telescopic adjustment devices. The telescopic adjustment device includes an inflation box 17, which is fixedly connected to one side wall of the fixed plate 2 and the movable plate 3. The inflation box 17 is positioned directly opposite the mounting hole. An empty slot 18 is provided inside the inflation box 17. The first rotating shaft 4 and the second rotating shaft 5 are fixedly connected to the first rotating shaft 4 away from the second rotating shaft 5. One end of each rotating shaft 5 is rotatably connected to an empty slot 18 inside the air box 17. Each of the first rotating shaft 4 and the second rotating shaft 5 has a connecting slot 19 on one side wall that communicates with the mounting hole. The connecting slot 19 is bent. The air box 17 is connected to an air pump through a pipe. The air pump inflates the air box 17 through the pipe. The connecting slot 19 is connected to the air box 17 through a conduit. By inputting high-pressure air into the connecting slot 19, part of the gravity effect is offset, thereby reducing friction and noise. The high-speed flow of high-pressure air out of the gap also helps to cool down the rotating connection.

[0032] The fixed plate 2 is equipped with a driving device, which includes a drive motor 20. The drive motor 20 is fixedly connected to one side wall of the fixed plate 2. A drive shaft 21 that passes through the fixed plate 2 is fixedly connected to the output end of the drive motor 20. A transmission wheel 22 is fixedly connected to both the first rotating shaft 4 and the drive shaft 21. The two transmission wheels 22 are connected by a transmission belt 23. A first one-way bearing is installed between the drive shaft 21 and the transmission wheel 22. The base 1 is equipped with a material picking device, which includes a first side plate 24 and a second side plate 25. Side plate 25, first side plate 24 and second side plate 25 are all fixedly connected to base 1. Drive shaft 21 is rotatably connected to first side plate 24. First side plate 24 and second side plate 25 are provided with transition grooves. Reciprocating screw 26 is rotatably connected in the transition groove. Reciprocating screw 26 is provided with slide 27. Slide 27 is fixedly connected to moving plate 3. Gear 28 is fixedly connected to drive shaft 21 and reciprocating screw 26. The two gears 28 are meshed. A second one-way bearing is installed between drive shaft 21 and gear 28.

[0033] When in use, high-pressure air is first injected into the air box 17 to keep the first rotating shaft 4, the second rotating shaft 5 and the regular polygonal rod 7 under high pressure. With the help of the pressure of the high-pressure air, the top plate 10 in the limiting groove 9 is driven to extend, which drives the first curved surface combined plate 11 to be pushed out. At the same time, the top rod 14 in the sliding groove 13 extends, which drives the second curved surface combined plate 15 to be pushed out. The sides of the first curved surface combined plate 11 and the second curved surface combined plate 15 are wedge-fitted and have the same curvature. The adjustable mandrel 6, which is spliced ​​together by multiple first curved surface combined plates 11 and second curved surface combined plates 15, is unfolded and spliced ​​tightly to form a normal mandrel that can receive meltblown cloth.

[0034] Then, the drive motor 20 is started to rotate forward. The output end of the drive motor 20 drives the drive shaft 21 to rotate. The drive shaft 21 drives the transmission wheel 22 to rotate by means of the one-way rotation restriction of the first one-way bearing. The two transmission wheels 22 are connected by the transmission belt 23, thereby driving the first rotating shaft 4 to rotate. The first rotating shaft 4 drives the second rotating shaft 5 to rotate synchronously through the limiting cooperation between the triangular slot and the triangular block, which in turn drives the adjustable mandrel 6 to rotate. Then, the production of meltblown fabric can begin.

[0035] After completing a meltblown fabric production cycle, when the rolled meltblown fabric needs to be removed, first turn off the drive motor 20, and then control the air pump to draw negative pressure into the first rotating shaft 4, the second rotating shaft 5 and the regular polygonal rod 7 through the air box 17. Under the action of negative pressure, the top plate 10 retracts into the limiting groove 9, and the top plate 10 drives the first curved surface combination plate 11 to move towards the regular polygonal rod 7. The top rod 14 retracts into the sliding groove 13, and the top rod 14 drives the second curved surface combination plate 15 to move towards the regular polygonal rod 7, thereby causing the adjustable mandrel 6 to contract. Then the meltblown fabric wound on its surface will detach from the surface of the adjustable mandrel 6 under the action of the mutual adhesion between the meltblown fibers.

[0036] Then, the drive motor 20 is reversed. The output of the drive motor 20 is limited by the unidirectional rotation of the drive shaft 21 and the second one-way bearing on it, which drives the gear 28 to rotate. The meshing connection between the two gears 28 drives the reciprocating screw 26 to rotate, thereby driving the slide 27 to move the moving plate 3 away from the fixed plate 2. The stretching causes the regular polygonal rod 7 on the first rotating shaft 4 and the regular polygonal rod 7 on the second rotating shaft 5 to separate, and the adjustable mandrel 6 to separate in the middle so that the workers can take out the meltblown cloth. After taking it out, the drive motor 20 is controlled to continue to rotate forward, and the reciprocating screw 26 can drive the slide 27 and the moving plate 3 to reset, align the first rotating shaft 4 and the second rotating shaft 5 together, restore the adjustable mandrel 6, and then prepare to start the next meltblown cloth production. Since there is no need to frequently change the mandrel, and the meltblown cloth is easy to pick up and operate, the processing and production efficiency can be significantly improved.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
