[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] like Figure 1-2 As shown, a mesh quilt hemming machine includes a frame 10, wherein the cotton batting 20 of the mesh quilt is fed from the front side of the frame 10 and discharged from the rear side; characterized in that an upper mesh placement roller 101 is fixed to the front side of the frame 10, and a lower mesh placement roller 102 is fixed to the rear side, wherein the upper mesh placement roller 101 and the lower mesh placement roller 102 are arranged in a direction perpendicular to the feeding direction, and the mesh quilt hemming machine also includes:

[0026] The cotton feeding and yarn wrapping mechanism comprises a conveyor belt 11 arranged along the feeding direction, the transmission shaft of the conveyor belt 1 being rotatably connected to the frame 10; a cotton pressing shaft group 12 fixed to the rear of the conveyor belt 11, the cotton pressing shaft group 12 comprising a cotton pressing shaft 121, a cotton pressing shaft 2 122, a cotton pressing shaft 3 123 and a cotton pressing shaft 4 124, the above four cotton pressing shafts are distributed in a square matrix style, parallel to each other and arranged perpendicular to the feeding direction; wherein, the cotton pressing shaft 2 122 is located below the cotton pressing shaft 1 121, the cotton pressing shaft 3 123 is located behind the cotton pressing shaft 1 121, and the cotton pressing shaft 4 124 is located below the cotton pressing shaft 3 123.

[0027] The edge wrapping conveying mechanism includes a conveyor belt 21 located above the conveyor belt 11 and opposite to its conveying direction, and the transmission shaft of the conveyor belt 21 can be rotatably connected to the frame 10; an edge wrapping shaft group 22 fixed to the rear of the conveyor belt 21, the edge wrapping shaft group 22 includes an edge wrapping shaft 1 221, an edge wrapping shaft 222, an edge wrapping shaft 3 223 and an edge wrapping shaft 4 224, and the above four edge wrapping shafts are distributed in a square matrix style, parallel to each other and arranged perpendicular to the feeding direction; wherein the edge wrapping shaft 222 is located below the edge wrapping shaft 1 221, the edge wrapping shaft 3 223 is located behind the edge wrapping shaft 1 221, and the edge wrapping shaft 4 224 is located below the edge wrapping shaft 3 223; an edge wrapping device 23 located on the conveyor belt 21, and the edge wrapping device 23 is fixed to the frame 10.

[0028] The pre-grinding discharging mechanism includes a conveyor belt three 31 located above the conveyor belt two 21 and in the same conveying direction as the conveyor belt one 11, and the transmission shaft of the conveyor belt three 31 is rotatably connected to the frame 10; a pre-grinding shaft group 32 fixed in front of the conveyor belt two 21, and the pre-grinding shaft group 32 includes a pre-grinding shaft one 321, a pre-grinding shaft two 322, a pre-grinding shaft three 323 and a pre-grinding shaft four 324 arranged vertically from top to bottom, and the above four pre-grinding shafts are parallel to each other and arranged perpendicular to the feeding direction; a pre-grinding plate 33 fixed on the frame 10, and the pre-grinding plate 33 is vertically arranged and contacts the tread of the cotton batt 20 transmitted on the pre-grinding shaft group 32.

[0029] During the operation of the hemming machine, the cotton batting 20 is transported from the feed end to the conveyor belt 11 and introduced between the cotton pressing shaft 121 and the cotton pressing shaft 2 122; at the same time, the upper gauze 30 enters from between the cotton pressing shaft 121 and the cotton pressing shaft 3 123 and covers the upper surface of the cotton batting 20, and is led out from between the cotton pressing shaft 3 123 and the cotton pressing shaft 4 124 together with the cotton batting 20; similarly, the lower gauze 40 enters from between the cotton pressing shaft 2 122 and the cotton pressing shaft 4 124 and covers the lower surface of the cotton batting 20, and is led out together with the above-mentioned cotton batting 20 and the upper gauze 30, thereby completing the mesh operation of the cotton batting 20.

[0030] Next, the cotton batting 20 with the completed mesh yarn is introduced between the hemming shaft three 223 and the hemming shaft four 224, and is further transported to the conveyor belt 2 21 through the hemming shaft one 221 and the hemming shaft two 222, and the hemming device 23 hems it.

[0031] Finally, the conveyor belt 21 delivers the hemmed cotton batt 20 to the pre-grinding shaft group 32 at its front end. The cotton batt 20 first enters between the pre-grinding shaft 4 324 and the pre-grinding shaft 3 323, then reverses to enter between the pre-grinding shaft 3 323 and the pre-grinding shaft 2 322, reverses to enter between the pre-grinding shaft 2 322 and the pre-grinding shaft 1 321 again, and finally transported to the conveyor belt 3 31 for the next process. At the same time, the pre-grinding plate 33 pre-grinds the cotton batt 20 on both sides of the pre-grinding shaft group 32.

[0032] After entering the pre-grinding shaft group 32, the cotton batt 20 is conveyed in an S-shaped trajectory, which can not only use the pre-grinding shaft group 32 to further compact the cotton batt 20, but also avoid the cotton wool falling off and the mesh being loose due to the friction of the pre-grinding plate 33 on the cotton batt 20, thereby ensuring that the cotton batt 20 is in a compacted state.

[0033] In addition, a plurality of upper gauze support tubes 103 and lower gauze support tubes 104 are fixed on the frame 10, and the upper gauze support tubes 103 are parallel to the upper gauze placement rollers 101, and are distributed at the front side of the frame 10 and below the conveyor belt 21. The lower gauze support tubes 104 are parallel to the lower gauze placement rollers 102, and are distributed at the rear side of the frame 10. Thus, the upper gauze 30 and the lower gauze 40 entering the cotton pressing shaft group 12 can be supported to prevent them from wrinkling and falling due to their light weight, and ensure that the gauze is laid in a stretched state.

[0034] The rollers used in the cotton pressing shaft group 12, the hemming shaft group 22 and the pre-grinding shaft group 32 of the hemming machine are all rubber shafts. In addition, the diameter of the middle part of the hemming shaft 221 is smaller than the diameter of its two ends, so that the extra cotton batt 20 on both sides of the mesh yarn can be bent, which is more conducive to the hemming device 23 to perform hemming.

[0035] In order to ensure that the hemming machine can adapt to the speed change of the entire production line, a buffer plate 105 is fixed at the feeding end of the frame 10, so that a portion of the cotton batt 20 can be stored on the buffer plate 105, and then introduced according to production needs, without causing the machine to stop and fail to work normally. In addition, the buffer plate 105 is horizontally arranged and its height is lower than the conveyor belt 11, so that when the cotton batt 20 enters the conveyor belt 11 from the buffer plate 105, it is in an upward introduction state, and the gravity pulling downwards will ensure that the cotton batt 20 is in a horizontal state without wrinkles.

[0036] An online platform 106 is also fixed at the feeding end of the frame 10, and the height of the online platform 106 is higher than the conveyor belt 11 and lower than the upper screen placement roller 101. It is convenient to install the screen in real time during production without affecting the normal machine operation.

[0037] The above are only preferred embodiments of the present invention. Any simple modification, deformation and equivalent substitution made by anyone to the present invention based on the contents of the present invention shall fall within the protection scope of the present invention.
