[0031] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0032] like Figures 1 to 8 As shown, the packaging device for non-woven fabric processing described in the embodiment of the present invention is particularly referred to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 The structure shown; comprises a bottom plate 1, wherein first support plates 11 are respectively provided at both ends of the bottom plate 1, a first roller 15 is rotatably installed inside the first support plate 11, a cloth roll 16 is placed above the first roller 15, a first convex block 111 is fixedly installed on the side wall of the bottom plate 1, a first telescopic rod 112 is fixedly installed on the top of the first convex block 111, a first spring 113 is provided on the outside of the first telescopic rod 112, a centering device 2 is rotatably installed on the top of the first telescopic rod 112, and the centering device 2 is provided with an extrusion device 3, and the extrusion device 3 comprises: A third telescopic rod 31 above the first support plate 11; a transmission round block 32 fixedly mounted at the end of the third telescopic rod 31; a power threaded rod 33 movably mounted inside the transmission round block 32; a rotating power block 36 fixedly mounted on the outer wall of the power threaded rod 33; a squeezing rod 37 rotatably mounted inside the rotating power block 36; a direction adjustment block 38 rotatably mounted at the end of the squeezing rod 37, an squeezing column 39 rotatably mounted inside the direction adjustment block 38; a paper adsorption rod 34 rotatably mounted at the end of the power threaded rod 33, and a paper adsorption block 341 fixedly mounted on the side wall of the paper adsorption rod 34.

[0033] It should be noted that, during the packaging process of the non-woven fabric, paper sheets need to be placed at both ends and then packaged with a film. However, if the packaging is only carried out by the tension of the film, the film is not easy to adhere to the two side walls. Therefore, the film needs to be squeezed during the packaging process so that the film adheres to the two side walls of the non-woven fabric roll (such as Figure 1 As shown, the cloth roll 16 is a non-woven fabric roll), in order to solve this problem, the following improvements are made:

[0034] First, the cloth roll 16 is placed on the first roller 15 through a clamping or transporting device, and then the film is pulled into the outer wall of the cloth roll 16 and rolled once, and then the first roller 15 is driven by a motor to rotate so that the film can be rolled on the outer wall of the cloth roll 16. In the process of rolling the protective film, a dislocation block 27 is provided on the centering device 2 to locate the center of the cloth roll 16, and the third telescopic rod 31 is started. The third telescopic rod 31 drives the transmission round block 32 and the power threaded rod 33 as well as the paper adsorption rod 34 and the paper adsorption block 341 to approach the side wall of the cloth roll 16, and the paper adsorption rod 34 is provided with an air pump inside, which can adsorb the paper on the side wall of the paper adsorption rod 34, and then the motor is started to rotate to drive the power threaded rod 33 and the limiting slide 331 to rotate, and the side wall of the transmission round block 32 is provided with a rounded corner 322, such as Figure 5 As shown, a torsion spring is provided inside the rotating power block 36 and the extrusion rod 37, so that the extrusion rod 37 is kept as Figure 5 When the paper adsorption block 341 contacts the side wall of the cloth roll 16, the transmission round block 32 continues to approach the direction of the cloth roll 16, and the rounded corner 322 lifts the end of the squeezing rod 37, thereby driving the squeezing rod 37, the direction adjustment block 38 and the squeezing column 39 to shrink toward the center of the cloth roll 16. When the cloth roll 16 completes the film pasting, the transmission round block 32 moves away from the side wall of the cloth roll 16, and the squeezing rod 37 drives the squeezing column 39 to open outward. At this time, the motor drives the power threaded rod 33 to rotate, which can drive the squeezing column 39 to squeeze the film on the side wall of the cloth roll 16, thereby adhering the film on the side wall of the cloth roll 16 to the outer wall of the cloth roll 16, thereby improving the packaging effect of the cloth roll 16 and reducing the problem of contaminants caused by poor edge sealing of the cloth roll 16 during transportation. After the cloth roll 16 is packaged, the cloth roll 16 is transported away again by a clamping or transportation device to carry out the next round of packaging.

[0035] Please pay attention to Figure 3 , Figure 4 , Figure 5In the structure shown, the extrusion device 3 also includes: a limiting slide 331 fixedly mounted on the side wall of the power threaded rod 33, and the limiting slide 331 is slidably mounted inside the transmission round block 32; a third spring 35 fixedly mounted on the side wall of the rotating power block 36, and the third spring 35 is concentric with the power threaded rod 33; an inner wall protrusion 321 fixedly mounted on the inner wall of the transmission round block 32, and the inner wall protrusion 321 slides on the outer wall of the power threaded rod 33.

[0036] It should be noted that, considering that it is not suitable to set a motor on the limiting slide 331 on the side wall of the power threaded rod 33, an inner wall protrusion 321 is set on the side wall of the transmission circle 32, and a third spring 35 is set on the outer wall of the power threaded rod 33. In the process of the third telescopic rod 31 driving the transmission circle 32 to approach the side wall of the cloth roll 16, the power threaded rod 33 can be driven to rotate, thereby driving the rotating power block 36 to rotate. The rotation of the rotating power block 36 drives the direction adjustment block 38 and the extrusion column 39 to rotate, thereby achieving the effect of squeezing the film on the side wall of the cloth roll 16.

[0037] Please pay attention to Figure 4 , Figure 5 In the structure shown, the extrusion device 3 also includes: a fillet 322 arranged on the outer wall of the transmission round block 32, a torsion spring is arranged at the connection between the rotating power block 36 and the extrusion rod 37; an inclined bracket 371 fixedly installed at the end of the extrusion rod 37, a torsion spring block 372 is arranged at the end of the inclined bracket 371, and an adjustment protrusion 381 is rotatably connected inside the torsion spring block 372, and the end of the adjustment protrusion 381 is fixedly connected to the direction adjustment block 38.

[0038] It should be noted that, considering that after the cloth roll 16 is packed, the films on both sides of the cloth roll 16 are squeezed and sealed, an inclined bracket 371 is provided at the end of the squeezing rod 37, and when the rotating power block 36 is connected to the squeezing rod 37, the squeezing rod 37 and the squeezing column 39 are kept, as shown in FIG. Figure 5 As shown in the state, when the transmission ball 32 approaches the side wall of the cloth roll 16, the rounded corner 322 lifts the end of the extrusion rod 37, so that the direction adjustment block 38 and the extrusion column 39 are squeezed toward the center of the cloth roll 16, and when the third telescopic rod 31 drives the transmission ball 32 and the power threaded rod 33 away from the side wall of the cloth roll 16, the extrusion column 39 contacts the film on the side wall of the cloth roll 16, thereby extruding and rolling, until the extrusion column 39 is no longer in contact with the side wall of the cloth roll 16, the extrusion column 39 has rolled to the outermost circle of the cloth roll 16, thereby completing the extrusion of the packaging film on the side wall of the cloth roll 16.

[0039] Please pay attention to Figure 5 In the structure shown, the power threaded rod 33 is concentric with the transmission round block 32, and the extrusion rods 37 are distributed in a circular array with the rotating power block 36 as the center.

[0040] It should be noted that the power threaded rod 33 is concentric with the transmission circle block 32, so that the extrusion column 39 can completely cover the packaging film on the side wall of the cloth roll 16 when squeezing it, and the extrusion rods 37 are distributed in a circular array with the rotating power block 36 as the center, so that the film on the side wall of the cloth roll 16 can contact with the extrusion column 39, thereby achieving the extrusion effect.

[0041] Please pay attention to Figure 6 , Figure 7 , Figure 8 According to the structure shown, the centering device 2 includes: a lifting roller 21 rotatably mounted on the top of the first telescopic rod 112; a first detection rod 211 rotatably mounted on the side wall of the lifting roller 21; a detection ring 22 rotatably mounted on the outer wall of the first detection rod 211; a second detection rod 28 fixedly mounted on the side wall of the first roller 15, and a first limiting ring 281 is rotatably mounted on the end of the second detection rod 28; a circular ring protrusion 221 fixedly mounted on the side wall of the detection ring 22, and two second telescopic rods 23 are fixedly mounted on the side wall of the circular ring protrusion 221; a slip ring 26 slidably mounted on the outer wall of the second telescopic rod 23, and a first center rod 29 and a second center rod 291 are fixedly mounted on the outer walls of the two slip rings 26, respectively, and a dislocation block 27 is slidably mounted on the outer walls of the first center rod 29 and the second center rod 291, and the side walls of the dislocation block 27 are fixedly mounted on the third telescopic rod 31.

[0042] It should be noted that, considering that when the film on the side wall of the cloth roll 16 is squeezed again, it is necessary to keep the squeezing device 3 at the center position of the cloth roll 16, so a centering device 2 is provided, and the centering device 2 can determine the center of the cloth roll 16 according to the position where the lifting roller 21 and the first roller 15 contact the outer wall of the cloth roll 16, and start the first telescopic rod 112. The first telescopic rod 112 drives the lifting roller 21 at the top to rise and fall. When the lifting roller 21 contacts the outer wall of the cloth roll 16, the position of the lifting roller 21 is determined. The lifting roller 21 is located directly below the cloth roll 16. The end of the first roller 15 is provided with a second detection rod 28 and a first limit ring 281, and the first limit The ring 281 is connected to the detection ring 22 through the second telescopic rod 23, and the outer wall of the second telescopic rod 23 is provided with a slip ring 26.

[0046] It should be noted that, considering that if the positions of the first center rod 29 and the second center rod 291 are the same, the first center rod 29 and the second center rod 291 will interfere with each other, causing the problem of difficulty in determining the position, the second telescopic rod 23 and the center rod 24 arranged at both ends of the detection ring 22 are staggered with each other, and the first center rod 29 and the second center rod 291 are staggered with each other.
