[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-4 This invention provides a technical solution: a meltblown machine die head rotation mechanism with adjustable width, comprising a large frame assembly 1, a die head rotation device 2, a hydraulic cylinder assembly 3, and a die head 26; the large frame assembly 1 is provided with two turntable fixing plates 4, and the die head rotation device 2 is rotatably mounted on the large frame assembly 1 via the two turntable fixing plates 4; the hydraulic cylinder assembly 3 is connected to one side of the die head rotation device 2; the die head rotation device 2 includes a frame layer 9, multiple steel plates 14, load-bearing wheels 12, a rotating base plate 8, a rotating upper fixing plate 15, and a rotating sleeve 13; the steel plates 14 are laid on the frame layer 9, and the die head 26 is installed at the lower end of the frame layer 9; the load-bearing wheels 12 are rotatably mounted on the turntable fixing plates 4; the rotating upper fixing plate 15 is fixed on the frame layer 9, and the rotating sleeve 13 is fixed on the rotating upper fixing plate 15; the rotating base plate 8 is fixed on the large frame assembly 1, and the rotating base plate 8 and the rotating sleeve 13 are connected by a plane bearing 19 to form a rotating pair.

[0022] The large frame assembly 1 includes a large frame platform 5, support columns 6, flat plates 7, and corner limiting blocks 20. The large frame platform 5 is constructed by bolting multiple square tubes and channel steel horizontally and vertically together. Multiple flat plates 7 are laid on the large frame platform 5, and the large frame platform 5 is supported and connected by multiple support columns 6. The corner limiting blocks 20 are fixed on the large frame platform 5 and located on one side of the die head rotating device 2. The large frame platform 5 provides an installation position for the die head rotating device 2 and can also support the die head rotating device 2.

[0023] Specifically, at least one reinforcing rod 16 is inclinedly arranged between the large frame platform 5 and the support column 6 to increase the load-bearing capacity of the large frame component 1.

[0024] The flat plate 7 serves as a cover on the large frame platform 5, providing a platform for workers to inspect and use the equipment, and also providing an installation position for the turntable fixing plate 4.

[0025] The corner limiting block 20 can limit the maximum rotation angle and the zero angle of the mold head rotating device 2. A photoelectric switch is installed on it to provide a braking signal for the pushing and retracting of the hydraulic cylinder 10.

[0026] The rotating base plate 8 is located at the front of the large frame platform 5 and is connected to two adjacent longitudinal channel steels of the large frame platform 5 by bolts. A plane bearing 19 is installed inside it as a rotating pair connected to the mold head rotating device 2. The turntable fixing plate 4 serves as a bearing device for the mold head rotating device 2 and is fixed to the flat plate 7 laid on the large frame platform 5 by welding.

[0027] The hydraulic cylinder assembly 3 includes a hydraulic cylinder 10, a piston rod 11, a hydraulic cylinder support 17, and a hydraulic cylinder support 18. The hydraulic cylinder support 17 is welded to the plate 7 and is located on the outer ring of the large frame assembly 1. The hydraulic cylinder support 18 is fixed to the side of the mold head rotating device 2. The hydraulic cylinder support 17 and the hydraulic cylinder support 18 are devices for the mold head rotating device 2 to receive the thrust and pull of the hydraulic cylinder 10. One end of the hydraulic cylinder 10 is fixed to the hydraulic cylinder support 17, and the other end of the hydraulic cylinder 10 is connected to the piston rod 11. The piston rod 11 and the hydraulic cylinder support 18 are connected.

[0028] The hydraulic cylinder support 17 and hydraulic cylinder support 18 provide support for the hydraulic cylinder 10 and piston rod 11 required for the rotation of the die head rotating device 2. During operation, the rotation of the die head rotating device 2 is achieved through the combined action of the rotating base plate 8, the plane bearing 19, the turntable fixing plate 4, and the hydraulic cylinder 10.

[0029] The first-layer frame 9 is welded from channel steel, which is arranged horizontally and vertically to form multiple rectangular spaces. Multiple steel plates 14 are laid on the front side of the first-layer frame 9 as needed.

[0030] The first-layer frame 9 is provided with a die head mounting plate 21, a metering pump mounting plate 22, a metering pump motor base 23, and an extruder motor base 24. The die head mounting plates 21 are symmetrically welded to the first-layer frame 9, and a rotating sleeve 13 is provided between the two sides of the die head mounting plates 21. The metering pump mounting plate 22 is located on the rear side of the rotating sleeve 13 and is aligned with the rotating sleeve 13. The metering pump motor base 23 is located on one side of the metering pump mounting plate 22 and is arranged parallel to the metering pump motor base 23. The extruder motor base 24 is installed on the rear side of the first-layer frame 9.

[0031] The mold head mounting plate 21 is provided with two straight slots 25, which are located on the outer side of the mold head mounting plate 21. The mold head 26 passes through the two straight slots 25 of the mold head mounting plate 21 via the upper part of the screw 27, and then the nut is screwed into the screw 27. At this time, the nut is stuck on the mold head mounting plate 21, and the lower part of the screw 27 is connected to the mold head 26. The entire mold head 26 can be hoisted onto the mold head rotating device 2 by the four screws 27 and rotate with the mold head rotating device 2.

[0032] In use, the metering pump motor base 23 and the metering pump mounting plate 22 are used to install the metering pump motor and the metering pump, respectively.

[0033] The die head 26 of the present invention needs to be connected to a material passage pipe during use. The material passage pipe is connected to the die head 26 through the rotating sleeve 13. At the same time, the material passage pipe is connected to the metering pump to control the feeding. The rotating sleeve 13 ensures that the die head rotating device 2 can rotate synchronously during feeding, without stopping work and affecting work efficiency.

[0034] The turntable fixing plate 4 serves as a support device for the mold head rotating device 2 and is fixed by welding to the flat plates 7 on the front and rear sides of the large frame assembly 1.

[0035] The load-bearing wheels 12 of the present invention are distributed on the front and rear sides of the mold head rotating device 2, and there are at least two load-bearing wheels 12 on each side, which are distributed on both sides of the mold head rotating device 2 so that the mold head rotating device 2 can maintain stability and synchronization during rotation.

[0036] The turntable fixing plate 4 has an arc-shaped structure, and the arc-shaped structures of both ends of the turntable fixing plate 4 are curved inward, so that the mold head rotating device 2 has a rotation angle and space on the turntable fixing plate 4. When the mold head rotating device 2 of the present invention is working, when the front side of the mold head rotating device 2 rotates to the right on the front side of the turntable fixing plate 4, the rear side of the mold head rotating device 2 rotates to the left on the rear side of the turntable fixing plate 4; when the front side of the mold head rotating device 2 rotates to the left on the front side of the turntable fixing plate 4, the rear side of the mold head rotating device 2 rotates to the right on the rear side of the turntable fixing plate 4.

[0037] Furthermore, the size of the turntable fixing plate 4 can be adjusted according to actual needs. In this invention, since the rear die head rotating device 2 has a large load-bearing capacity, the rear turntable fixing plate 4 adopts a larger structure. Correspondingly, there are two load-bearing wheels 12 on the front side of the die head rotating device 2, located on both sides of the die head rotating device 2; and four load-bearing wheels 12 on the rear side of the die head rotating device 2, forming a two-row structure located on both sides of the die head rotating device 2.

[0038] The rotating base plate 8 is located on the front side of the large frame assembly 1 and is connected to the large frame assembly 1 by bolts. A plane bearing 19 is installed inside the rotating base plate 8 as a rotating pair connected to the mold head rotating device 2.

[0039] The rotating upper fixing plate 15 is located at the lower end of the first layer frame 9, so that the rotating upper fixing plate 15 and the mold head rotating device 2 are directly and fixedly connected through the fixing between the rotating upper fixing plate 15 and the first layer frame 9.

[0040] In use, the rotating base plate 8 fixed on the large frame assembly 1 and the internal planar bearing 19, and the rotating upper fixing plate 15 and rotating sleeve 13 fixed on the first layer frame 9 are such that when the die head rotating device 2 rotates, the rotating sleeve 13 has the degree of freedom to rotate with the material passage pipe passing through the rotating sleeve 13 as the center, so that the rotation of the die head rotating device 2 does not affect the feeding.

[0041] The die head rotating device 2 provides an installation position for the extruder, heating tank, screen changer, metering pump, die head, and material path of the meltblown machine.

[0042] When the die head rotating mechanism of the present invention is working, the hydraulic cylinder 10 drives the piston rod 11, causing the frame 9 connected to the piston rod 11 to rotate; when rotating, the load-bearing wheel 12 rolls on the turntable fixing plate 4, and the load-bearing wheels 12 on both sides rotate in opposite directions; when the die head rotating device 2 rotates on the turntable fixing plate 4, the die head rotating device 2 rotates around the material passage pipe as the center, so that the rotating mechanism does not affect the feeding when rotating, and the rotating sleeve 13 has the rotational freedom of the rotating mechanism.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
