[0001] The utility model relates to the field of PE film production equipment, in particular to a stirring and blending device for PE film production. Background Art

[0002] At present, with the development of science and technology, mixing is an indispensable processing step in the plastic processing industry, especially in the processing of PE film, where a variety of powder additives need to be stirred and mixed with the main raw materials to form a mixture and then processed into functional PE film. In the existing material mixing process, due to the unreasonable design of the device, the materials cannot be fully mixed, and the powder additives are easily agglomerated after being added at one time, resulting in uneven mixing of the materials, which affects the production quality of the PE film.

[0003] Furthermore, when adding powder, the position of the feed port is fixed, so that the newly added powder tends to accumulate on the lower side of the feed port and is not easy to be quickly dispersed to various areas in the mixing tank during the mixing process, thereby affecting the powder mixing efficiency. Utility Model Content

[0004] The utility model aims to provide a stirring and blending device for producing PE films, which can improve the stirring uniformity and efficiency between powder materials.

[0005] In order to solve the above technical problems, the utility model provides a stirring and blending device for PE film production, including a tank body, a cover body covered at the top opening of the tank body, and a rotating shaft rotatably arranged on the cover body, the top of the rotating shaft has a feed port, the rotating shaft has a discharge port opened along the circumference, and the feed port is connected to the discharge port, the rotating shaft has several stirring rod groups distributed along the axial direction, and the stirring rod group includes at least two stirring rods distributed along the circumference of the rotating shaft, and a push plate is movably arranged on the stirring rod, and the push plate can move back and forth along the axial direction of the stirring rod.

[0006] Furthermore, a positioning ring is provided on the outer periphery of the tank body, and a plurality of driving plates are arranged circumferentially on the inner side of the positioning ring. The driving plates are matched with the push plates so that the driving plates can adsorb or repel the push plates.

[0007] Furthermore, two adjacent stirring rod groups are overlapped by a connecting component, and the connecting component includes a connecting piece and a connecting groove. The connecting piece is clamped in the connecting groove, and the connecting piece is arranged on the push plate of one of the stirring rod groups, and the connecting groove is arranged on the push plate of the other stirring rod group.

[0008] Furthermore, a plurality of connecting rods are provided between the discharge port and the feed port.

[0009] Furthermore, a funnel is provided on the side of the feed port away from the discharge port.

[0010] Furthermore, a first driving wheel is provided on the outer periphery of the rotating shaft, and a second driving wheel is rotatably provided on the outer side of the cover body, and the first driving wheel and the second driving wheel are in meshing cooperation.

[0011] Furthermore, a retaining ring is provided at the bottom of the outer periphery of the tank body, a positioning ring is placed on the retaining ring, and a plurality of positioning rods are circumferentially arranged on one side of the retaining ring close to the retaining ring, and a plurality of positioning holes matching the positioning rods are opened on the side of the retaining ring close to the positioning ring.

[0012] Furthermore, both sides of the push plate have guiding arc surfaces.

[0013] Furthermore, a paddle is provided on the outer side of the positioning ring.

[0014] The beneficial effect of the present invention is that the powder is replenished from the feed port and enters the interior of the tank from the discharge port.

Therefore, the above terms cannot be understood as limiting the present invention.

[0023] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0024] like Figure 1-Figure 5 The utility model provides a stirring and blending device for PE film production, including a tank body 1, a cover body 2 covered at the top opening of the tank body 1, and a rotating shaft 3 rotatably arranged on the cover body 2, the top of the rotating shaft 3 has a feed port 4, the rotating shaft 3 is provided with a discharge port 5 along the circumferential direction, and the feed port 4 is connected to the discharge port 5, the rotating shaft 3 has several stirring rod groups distributed along the axial direction, and the stirring rod group includes at least two stirring rods 6 distributed along the circumferential direction of the rotating shaft 3, and a push plate 7 is movably arranged on the stirring rod 6, and the push plate 7 can move back and forth along the axial direction of the stirring rod 6.

[0025] The powder is added from the feed port and enters the tank from the discharge port. At this time, the rotating shaft drives several stirring rods to rotate and stir. Since the push plate can reciprocate along the axial direction of the stirring rod, the stirring rod can stir the powder circumferentially of the tank during the stirring process, and the push plate can stir the powder radially of the tank. The push plate can also push the powder on the inside to the periphery for diffusion, and pull the powder on the periphery to the inside, thereby greatly improving the uniformity of the powder stirring process and helping the newly added powder to diffuse and stir quickly.

[0026] The tank body and the cover body are connected by means of threads, snaps, etc.; the cross-section of the stirring rod can be rectangular, elliptical, etc. to avoid the push plate from rotating relative to the stirring rod.

[0027] Preferably, a positioning ring 8 is provided on the outer periphery of the tank body 1 , and a plurality of driving plates 9 are arranged circumferentially on the inner side of the positioning ring 8 . The driving plates 9 are matched with the push plate 7 so that the driving plates 9 can adsorb or repel the push plate 7 .

[0028] Specifically, several drive plates are limited by positioning rings. At the same time, since the drive plates can adsorb or repel the push plates, when the push plates rotate with the rotating shaft to the corresponding drive plates, the drive plates can be adsorbed or repelled by the drive disc, thereby controlling the movement of the push plates relative to the stirring rod.

[0029] Among them, the push plate and the driving plate are both made of magnets, and one part of the driving plate is installed in an adsorption fit with the push plate, while the other part of the driving plate is installed in a repulsive fit with the push plate to ensure the reciprocating movement of the push plate.

[0030] Preferably, two adjacent stirring rod groups are overlapped by a connecting assembly, and the connecting assembly includes a connecting piece 10 and a connecting groove 11. The connecting piece 10 is snapped into the connecting groove 11, and the connecting piece 10 is arranged on the push plate 7 of one of the stirring rod groups, and the connecting groove 11 is arranged on the push plate 7 of the other stirring rod group.

[0031] Specifically, by snapping the connecting plate into the connecting groove, when the push plate in a certain stirring rod group is driven by the driving plate, the push plate in another stirring rod group can be driven to move through the connecting component, thereby reducing equipment costs and ensuring stable stirring of powders at different levels.

[0032] Preferably, a plurality of connecting rods 12 are provided between the discharge port 5 and the feed port 4 .

[0033] Specifically, since the discharge port is opened along the circumference of the rotating shaft, in order to avoid the situation where the two ends of the rotating shaft cannot be connected, the inner side of the rotating shaft is connected through a connecting rod to ensure the stable transmission of the rotating shaft and the circumferential stable discharge of the discharge port.

[0034] Preferably, a funnel 13 is provided on the side of the feed port 4 away from the discharge port 5 so that the feed can be added and supplemented from the funnel, thereby increasing the stability and convenience of the feed.

[0035] Preferably, a first driving wheel 14 is provided on the outer periphery of the rotating shaft 3 , and a second driving wheel 15 is rotatably provided on the outer side of the cover body 2 , and the first driving wheel 14 and the second driving wheel 15 are in meshing cooperation.

[0036] Specifically, the second driving wheel drives the first driving wheel to rotate, thereby ensuring stable rotation of the rotating shaft and stable stirring.

[0037] Wherein, a motor is provided on the outside of the cover body, and the output end of the motor is connected to the second driving wheel to ensure the rotation of the second driving wheel.

[0038] Preferably, the outer bottom of the tank body 1 has a retaining ring 16, the positioning ring 8 is placed on the retaining ring 16, and a plurality of positioning rods 17 are circumferentially arranged on the side of the positioning ring 8 close to the retaining ring 16, and a plurality of positioning holes 18 matching the positioning rods 17 are opened on the side of the retaining ring 16 close to the positioning ring 8.

[0039] Specifically, the bottom of the positioning ring is supported by a retaining ring to ensure that the height position of the positioning ring is accurate. Then, when installing the positioning ring, the positioning rod can be inserted into the positioning hole to ensure that the positioning ring will not rotate relative to the outer periphery of the tank body, thereby ensuring the stability of the reciprocating movement of the push plate.

[0040] Preferably, the push plate 7 has guide arc surfaces on both sides, so that when the push plate rotates with the stirring rod for stirring, the powder can be pushed away on both sides by the guide arc surfaces to reduce the resistance of the powder to the side of the push plate.

[0041] Preferably, the outer side of the positioning ring 8 has a paddle 19, so that when the positioning ring needs to be replaced, the positioning ring can be easily lifted off the outer periphery of the tank body by the paddle after the cover is opened, so as to facilitate the replacement of positioning rings with different numbers and arrangements of drive plates.

[0042] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that is the same or similar to that of the present application falls within the scope of protection of the present invention.
