[0026] The positioning component 2 includes two limit plates 7. The two limit plates 7 are vertically arranged, parallel to each other, and symmetrically arranged with respect to the center line of the workbench 1 in the width direction.

[0027] On one side of each of the two limit plates 7 facing away from each other, two first hydraulic telescopic cylinders 8 are provided. The two first hydraulic telescopic cylinders 8 are respectively arranged at both ends of the limit plate 7 in the length direction. The output end of the first hydraulic telescopic cylinder 8 is fixedly connected to the limit plate 7, and the fixed end of the first hydraulic telescopic cylinder 8 is fixedly connected to a first connecting plate 9. The first connecting plate 9 is vertically arranged and fixedly connected to the workbench 1.

[0028] Between the two limit plates 7 is used for conveying the foam cotton. The foam cotton is positioned by the two limit plates 7 so that the center line of the foam cotton in the width direction coincides with the center line of the workbench 1 in the width direction.

[0029] According to the different widths of the foam cotton, the telescopic length of the output end of the first hydraulic telescopic cylinder 8 is controlled so that the limit plates 7 can limit and position foam cotton of different widths.

[0030] The flattening component 3 includes two horizontally arranged pressing rollers 10. The two pressing rollers 10 are linearly arranged along the length direction of the workbench 1, and the axial directions of the two pressing rollers 10 are parallel to the width direction of the workbench 1. The two pressing rollers 10 roll and convey the foam cotton passing through the positioning component 2.

[0031] At both ends of the two pressing rollers 10 along the axial direction, they are rotatably connected to a first bracket 11. On the upper side of one end of the first bracket 11 along the width direction of the workbench 1, a first driving motor 12 is fixedly connected. The output end of the first driving motor 12 is connected with a conveyor belt. One end of the conveyor belt passes through the first bracket 11 and is belt-connected to the roller shaft of the pressing roller 10, thereby driving the pressing roller 10 to rotate.

[0032] A second hydraulic telescopic cylinder 13 is arranged on the lower side of the first bracket 11. The fixed end of the second hydraulic telescopic cylinder 13 is fixedly connected to the workbench 1, and the output end of the second hydraulic telescopic cylinder 13 is fixedly connected to the first bracket 11. By controlling the telescopic length of the output end of the second hydraulic telescopic cylinder 13, the pressing roller 10 is lifted and lowered, thereby rolling and conveying foam cotton of different thicknesses.

[0033] There are two sets of trimming components 4, which are symmetrically arranged with respect to the center line of the workbench 1 in the width direction. The trimming component 4 includes a trimming knife 14. The trimming knife 14 is vertically arranged. A connecting block 15 is arranged on the upper side of the trimming knife 14. On the side of the connecting block 15 away from the trimming knife 14, a third hydraulic telescopic cylinder 16 is arranged. The third hydraulic telescopic cylinder 16 is vertically arranged. The fixed end of the third hydraulic telescopic cylinder 16 is fixedly connected to a machine frame 17, and the output end of the third hydraulic telescopic cylinder 16 is fixedly connected to the connecting block 15.

[0034] When the foamed cotton needs to be cut, the output end of the hydraulic telescopic cylinder three 16 is controlled to extend, the trimming knife 14 descends and the lower side of the trimming knife 14 abuts against the tabletop of the workbench 1, and the foamed cotton is trimmed.

[0035] On both sides of the trimming knife 14 along the width direction of the workbench 1, there are pressing wheels 18. On the side of the pressing wheel 18 away from the trimming knife 14, there is a second driving motor 19. The output end of the second driving motor 19 is connected to the pressing wheel 18 to drive the pressing wheel 18 to rotate.

[0036] By arranging the pressing wheels 18 on both sides of the trimming knife 14, the two sides of the foamed cotton that need to be trimmed are pressed tightly, improving the precision of the trimming by the trimming knife 14.

[0037] A motor housing 20 is sleeved on the second driving motor 19. On the upper side of the motor housing 20, there is a hydraulic telescopic cylinder four 21. The hydraulic telescopic cylinder four 21 is vertically arranged. The fixed end of the hydraulic telescopic cylinder four 21 is fixedly connected to the frame 17, and the output end of the hydraulic telescopic cylinder four 21 is fixedly connected to the motor housing 20.

[0038] By controlling the expansion and contraction of the output end of the hydraulic telescopic cylinder four 21, the pressing wheel 18 is lifted and lowered to press and roll the foamed cotton with different thicknesses.

[0039] On one side of the frame 17 close to the long side of the workbench 1, there are two hydraulic telescopic cylinders five 22. The two hydraulic telescopic cylinders five 22 are horizontally arranged up and down. The fixed end of the hydraulic telescopic cylinder five 22 is fixedly connected with a fixing frame 23. The fixing frame 23 is in an "L" shape and is fixedly connected to the workbench 1.

[0040] By controlling the expansion and contraction of the output end of the hydraulic telescopic cylinder five 22, the movement of the frame 17 and the pressing wheel 18 and the trimming knife 14 on the frame 17 is controlled, thereby controlling the width of the foamed cotton that needs to be trimmed.

[0041] The cutting component 5 includes a first rotating roller 24 arranged horizontally. The axis direction of the first rotating roller 24 is parallel to the width direction of the workbench 1. The first rotating roller 24 rolls and conveys the foamed cotton passing through the trimming component 4.

[0042] Both ends of the first rotating roller 24 along the axis direction are rotatably connected with a second bracket 25. On the upper side of one end of the second bracket 25 along the width direction of the workbench 1, there is a third driving motor 26. The output end of the third driving motor 26 is connected with a conveyor belt. One end of the conveyor belt passes through the second bracket 25 and is connected with the roller shaft of the first rotating roller 24, thereby driving the first rotating roller 24 to rotate.

[0043] An encoder 27 is arranged at one end of the second bracket 25 along the width direction of the workbench 1. The encoder 27 is connected with the roller shaft of the first rotating roller 24. The length of the foamed cotton rolled and conveyed by the first rotating roller 24 is calculated through the encoder 27.

[0044] A hydraulic telescopic cylinder six 28 is provided on the lower side of the support two 25. The fixed end of the hydraulic telescopic cylinder six 28 is fixedly connected to the workbench 1, and the output end of the hydraulic telescopic cylinder six 28 is fixedly connected to the support two 25.

[0045] By controlling the telescopic movement of the output end of the hydraulic telescopic cylinder six 28, the roller one 24 is lifted and lowered, so as to roll and convey the foam cotton with different thicknesses.

[0046] The cutting component 5 further includes a cutting knife 29. The cutting knife 29 is vertically arranged, located above the workbench 1, and is arranged on one side of the workbench 1 along the length direction and away from the edge trimming component 4 relative to the roller one 24.

[0047] Hydraulic telescopic cylinders seven 30 are arranged at both ends of the cutting knife 29 along the width direction of the workbench 1. The hydraulic telescopic cylinders seven 30 are vertically arranged. The fixed end of the hydraulic telescopic cylinder seven 30 is fixedly connected to the workbench 1, and the output end of the hydraulic telescopic cylinder seven 30 is fixedly connected to the cutting knife 29 through a connecting plate two 31.

[0048] When the encoder 27 calculates that the length of the foam cotton rolled and conveyed by the roller one 24 reaches the length required for cutting the foam cotton, the foam cotton is cut by the cutting knife 29.

[0049] The discharging component 6 includes two horizontally arranged rollers two 32. The axial line direction of the rollers two 32 is parallel to the width direction of the workbench 1, and the rollers two 32 roll and convey the foam cotton passing through the cutting component.

[0050] Both ends of the roller two 32 along the axial direction are rotatably connected with supports three 33. A driving motor four 35 is fixedly connected to the upper side of one end of the support three 33 along the width direction of the workbench 1. The output end of the driving motor four 35 is connected with a conveyor belt. One end of the conveyor belt passes through the support three 33 and is belt-connected to the roller shaft of the roller two 32, so as to drive the roller two 32 to rotate.

[0051] A hydraulic telescopic cylinder eight 34 is provided on the lower side of the support three 33. The fixed end of the hydraulic telescopic cylinder eight 34 is fixedly connected to the workbench 1, and the output end of the hydraulic telescopic cylinder eight 34 is fixedly connected to the support three 33.

[0052] By controlling the telescopic movement of the output end of the hydraulic telescopic cylinder eight 34, the roller two 32 is lifted and lowered, so as to roll and convey the foam cotton with different thicknesses.

[0053] In this embodiment, the foam cotton is unrolled by an unrolling device. The unrolled foam cotton is manually pulled through the positioning component 2 and is rolled and fixed by the pressure roller 10 on the flattening component 3. During this process, the limiting plate 7 on the positioning component 2 limits and positions the width of the foam cotton under the control of the hydraulic telescopic cylinder one 8.

[0054] After the foam cotton is limited and positioned by the positioning component 2 and rolled and flattened by the pressure roller 10, it moves towards the trimming component side under the traction of the pressure roller 10.

[0055] According to actual requirements, control the expansion and contraction of the output end of the hydraulic telescopic cylinder five 22, so that the trimming knife 14 moves along the width direction of the foam cotton to the position where trimming is required. At the same time, control the output ends of the hydraulic telescopic cylinder three 16 and the hydraulic telescopic cylinder four 21 to extend, respectively, so that the trimming knife 14 and the pressure wheel 18 descend. The trimming knife 14 descends until the lower side of the trimming knife 14 abuts against the upper surface of the workbench 1, and the pressure wheel 18 descends until the lowest side of the wheel surface of the pressure wheel 18 contacts the upper surface of the foam cotton. Thus, while the pressure wheel 18 rolls and conveys the foam cotton, the trimming knife 14 can trim the foam cotton.

[0056] The foamed cotton part after trimming moves towards the cutting component 5 side under the rolling and conveying of the pressure wheel 18, and the rotating roller two 32 rolls and conveys the trimmed foamed cotton part. When the encoder 27 calculates that the length of the foamed cotton rolled and conveyed by the rotating roller one 24 reaches the length required for cutting the foamed cotton, the foamed cotton is cut by the cutting knife 29. After cutting is completed, the foamed cotton is transported out by the transporting component 6 and then collected and packed manually. The trimmed part of the foamed cotton after cutting is transported out by the transporting component 6 and then recycled manually.
