[0034] The driving mechanism 4 includes a driving motor 41, a long shaft 42 and a synchronization component 43, see Figure 1 and Figure 2 As shown, a long shaft 42 is rotatably connected between the left and right rear parts of the outer top of the mounting frame 1, and a synchronous component 43 is connected between the left and right sides of the long shaft 42 and the spline parts of the left and right sliding rods 3 respectively. The synchronous component 43 consists of two pulleys and a flat belt, one of which is fixedly mounted on the long shaft 42, and the other pulley is slidably mounted on the spline part of the sliding rod 3, and the flat belt is wound between the two pulleys. A driving motor 41 is fixedly connected to the rear right side of the outer top of the mounting frame 1, and the output shaft end of the driving motor 41 is connected to the right end of the long shaft 42 through a coupling.

[0035] The fixing mechanism 5 includes a chuck 51, a first spring 52 and a guide rod 53, see Figure 1 and Figure 3 As shown, chucks 51 are slidably mounted on the first spline shafts 22 on the left and right sides, and the chucks 51 on the left and right sides are located on the left and right sides of the placement roller 2. The chucks 51 on the left and right sides are in contact with the placement roller 2, and the chucks 51 can limit the placement roller 2. Guide rods 53 are symmetrically slidably connected to the upper parts of the left and right support frames 21 in a front-to-back manner. The right ends of the two guide rods 53 on the left are fixedly connected to the left side of the left chuck 51, and the left ends of the two guide rods 53 on the right are fixedly connected to the right side of the right chuck 51. When the chuck 51 moves, the guide rods 53 can guide the chuck 51. First springs 52 are symmetrically connected to the outer sides of the left and right chucks 51 on the left and right sides, and the four first springs 52 are respectively mounted on the four guide rods 53.

[0036] When the cam 3 is in the upright position, the cam 3 is pulled back to move to the left and right sides, and the cam 3 is in the upright position, the cam 3 is in the upright position, and the cam 3 is in the upright position. The packaging sticker is then removed by pulling the sliding rods 3 on both sides out of the way and moving them back and forth, and the packaging sticker is then removed by pulling the sliding rods 3 on both sides out of the way and moving them back and forth.

[0037] When the head end of the weed-proof cloth is attached to the front side of the weed-proof cloth, the driving motor 41 is started to reverse, and the reversal of the driving motor 41 drives the long shaft 42 to reverse, and the reversal of the long shaft 42 drives the left and right synchronous components 43 to reverse, and the reversal of the left and right synchronous components 43 drives the left and right sliding rods 3 to reverse, and the reversal of the left and right sliding rods 3 drives the weed-proof cloth to reverse, and the reversal of the weed-proof cloth rolls up the packaging sticker, and the weed-proof cloth is packaged.

When the left and right side chucks 51 move outward to a suitable position, the placement roller 2 can be removed from the left and right first spline shafts 22, and then the packaging sticker is put on the placement roller 2. When the packaging sticker is put on the placement roller 2, the placement roller 2 is put back between the left and right first spline shafts 22, and the left and right side chucks 51 are released. Due to the action of the four first springs 52, the left and right side chucks 51 move inward and reset to contact the placement roller 2. The left and right side chucks 51 limit the placement roller 2, and the head end of the packaging sticker can be pulled downward to stick to the front side of the grass-proof cloth, and the grass-proof cloth can be packaged. Then, when the packaging sticker is rolled up, the packaging sticker drives the placement roller 2 to reverse, and the left and right side chucks 51 can prevent the placement roller 2 from moving and affecting the packaging of the grass-proof cloth.

[0039] Example 2

[0040] On the basis of embodiment 1, a laminating mechanism 6 is also included. The laminating mechanism 6 includes a rotating disk 61, a cutting plate 62, a second spline shaft 63, a column gear 64, a spiral spring 65, a one-way clutch 66 and an outer gear ring 67. Figure 1 , Figure 4 and Figure 5 As shown, the lower parts of the inner sides of the left and right support plates 23 are rotatably connected with a turntable 61, and a cutting plate 62 is installed between the rear sides of the inner sides of the left and right turntables 61 by welding. When the cutting plate 62 is reversed, the cutting plate 62 can press the packaging sticker on the weed-proof cloth and cut the weed-proof cloth. The outer sides of the left and right turntables 61 are circumferentially connected with a one-way clutch 66, and the middle parts of the upper parts of the left and right support frames 21 are rotatably connected with a second spline shaft 63, and the right side of the left second spline shaft 63 is connected to the outer side of the left one-way clutch 66. The transmission is transmitted by a synchronous belt, and the transmission is also transmitted by a synchronous belt between the left side of the right second spline shaft 63 and the outer side of the right one-way clutch 66. The outer sides of the left and right second spline shafts 63 are slidably covered with column gears 64, and the outer sides of the left and right first spline shafts 22 are fixedly covered with outer ring gears 67. The left and right outer ring gears 67 are respectively meshed with the left and right column gears 64, and the outer sides of the left and right first spline shafts 22 are respectively connected to the upper parts of the outer sides of the left and right support frames 21 with spiral springs 65, and the spiral springs 65 are located between the outer ring gears 67 and the support frame 21.

[0041] Also includes a limit block 68, see Figure 4 As shown, the outer ends of the second spline shafts 63 on the left and right sides are fixedly connected to the limit blocks 68.

[0042] The sealing mechanism 7 includes a cam 71, a contact frame 72, a support plate 73, a second spring 74, a mounting plate 75, a hollow rod 76, a shift block 77, a pull wire 78 and a third spring 79. Figure 1 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, a hollow rod 76 is fixedly connected between the lower portions of the left and right support frames 21, and the left and right sliding rods 3 pass through the left and right hollow rods 76 respectively. The inner ends of the left and right hollow rods 76 are installed with mounting plates 75 by welding. The middle portions of the inner sides of the left and right mounting plates 75 are slidably connected with three shifting blocks 77 evenly spaced along the circumferential direction. When the shifting blocks 77 move inward, the shifting blocks 77 can press the edge of the packaging sticker onto the weed-proof cloth. The inner sides of the three shifting blocks 77 on the left are connected to the right side of the left mounting plate 75 by a third spring 79, and the inner sides of the three shifting blocks 77 on the right are also connected to the left side of the right mounting plate 75 by a third spring 79. The left side of the left sliding rod 3 and the right side of the right sliding rod 3 are connected to three pull wires 78. The tail ends of the three pull wires 78 on the left pass through the left hollow rod 76 and are fixedly connected to the inner sides of the three shifting blocks 77 on the left. The tail end of wire 78 passes through the right hollow rod 76 and is fixedly connected with the inner side surfaces of the three right shift blocks 77. When the wire 78 moves, the wire 78 can drive the shift block 77 to move inward. The three wires 78 on the left and right sides contact the left and right mounting plates 75 respectively. The upper front sides of the left and right side surfaces of the mounting frame 1 are installed with support plates 73 by welding. The upper portions of the left and right support plates 73 are respectively connected with contact frames 72 in a sliding manner between the middle portions of the left and right support plates 23. The tail ends of the contact frames 72 are close to the turntable 61, and the contact frames 72 move outward to contact the outer ends of the sliding rods 3. The inner sides of the left and right contact frames 72 are respectively connected with second springs 74 between the left and right support plates 73 and the support plates 23. The outer sides of the left and right turntables 61 are fixedly sleeved with cams 71 along the circumferential direction. When the cams 71 reverse and contact the contact frames 72, the cams 71 can drive the contact frames 72 to move outward.

[0043] When the drive motor 41 is started, the sliding rods 3 on the left and right sides reverse and drive the one-way clutches 66 on the left and right sides to rotate idly. At the same time, the reversal of the first spline shafts 22 on the left and right sides also compresses the volute springs 65 on the left and right sides. The reversal of the first spline shafts 22 on the left and right sides also drives the outer gear rings 67 on the left and right sides to reverse. The reversal of the outer gear rings 67 on the left and right sides drives the column gears 64 on the left and right sides to rotate forward. The forward rotation of the column gears 64 on the left and right sides drives the second spline shafts 63 on the left and right sides to rotate forward. The forward rotation of the second spline shafts 63 on the left and right sides drives the one-way clutches 66 on the left and right sides to rotate idly through the synchronous belt transmission, and then the anti-grass cloth reverses to wrap the packaging. When the sticker is reversed, the packaging sticker contacts the cutting plate 62, and the cutting plate 62 makes the packaging sticker close to the grass-proof cloth for packaging. When the packaging sticker is rolled around the grass-proof cloth, it means that the grass-proof cloth is packaged. The driving motor 41 is turned off, and the sliding rods 3 on the left and right sides stop driving the one-way clutch 66 to reverse. At the same time, the first spline shafts 22 on the left and right sides also stop reversing. Due to the action of the volute springs 65 on the left and right sides, the first spline shafts 22 on the left and right sides rotate forward to drive the outer gear rings 67 on the left and right sides to rotate forward, and the outer gear rings 67 on the left and right sides rotate forward to drive the column gears 64 on the left and right sides to reverse, and the column gears 64 on the left and right sides reverse to drive the left and right sides to rotate forward. The second spline shafts 63 on the right side reverse, and the second spline shafts 63 on the left and right sides reverse and drive the turntables 61 on the left and right sides to reverse through the synchronous belt drive, and the turntables 61 on the left and right sides reverse and drive the one-way clutches 66 on the left and right sides to reverse, and the one-way clutches 66 on the left and right sides reverse and drive the turntables 61 on the left and right sides to reverse, and the turntables 61 on the left and right sides reverse and drive the cutting plate 62 to reverse, and the cutting plate 62 reverses to cut the packaging sticker, and the operator can pull the sliding rods 3 on the left and right sides to move outward to loosen the weed-proof cloth, remove the packaged weed-proof cloth, and then pull the column gears 64 on the left and right sides to move outward and not mesh with the outer gear rings 67 on the left and right sides. Due to the action of the stopper 68, the column gear 64 can be prevented from being separated from the second spline shaft 63, and then the cutter plate 62 is pulled to reset in forward rotation, and the cutter plate 62 is reset in forward rotation to drive the left and right turntables 61 to reset in forward rotation, and the left and right turntables 61 are reset in forward rotation to drive the left and right one-way clutches 66 to reset in forward rotation, and the left and right one-way clutches 66 are reset in forward rotation to drive the left and right second spline shafts 63 to reset in forward rotation through the synchronous belt transmission, and the left and right second spline shafts 63 are reset in forward rotation to drive the left and right column gears 64 to reset in forward rotation, and then the left and right column gears 64 are pulled inward to reset and mesh with the left and right outer gear rings 67. In this way, the packaging sticker can be more closely attached to the anti-grass cloth, and the anti-grass cloth can be cut off.

[0044] When the operator pulls the head end of the packaging sticker to stick to the front side of the weed-proof cloth, the head end of the packaging sticker is located on the inner side of the shifting block 77, and the packaging sticker contacts the inner side of the shifting block 77. Then, when the weed-proof cloth is reversed to roll up the packaging sticker, the packaging sticker is continuously rolled up and contacts the inner side of the shifting block 77. When the packaging sticker wraps the weed-proof cloth, and the left and right turntables 61 reverse to drive the cutting plate 62 to reverse, the left and right turntables 61 also drive the left and right cams 71 to reverse, and the left and right cams 71 reverse to contact the left and right contact frames 72. When the left and right cams 71 are in contact, the left and right contact frames 72 move outward, and the four second springs 74 are stretched. When the left and right contact frames 72 move outward and contact the left and right sliding rods 3, the left and right contact frames 72 drive the left and right sliding rods 3 to move outward, and the left and right sliding rods 3 move outward and break away from the weed-proof cloth, and the cutting plate 62 supports the weed-proof cloth. The left and right sliding rods 3 move outward and drive the six pull wires 78 to move outward, and the six pull wires 78 move outward through the left and right mounting plates. 75 drives the six shifting blocks 77 to move inwards, and the six third springs 79 are compressed. The three shifting blocks 77 on the left move inwards and drive the left edge of the packaging sticker to swing inwards and fit tightly against the anti-grass cloth. The three shifting blocks 77 on the right move inwards and drive the right edge of the packaging sticker to swing inwards and fit tightly against the anti-grass cloth. Then, when the cutting plate 62 reverses to cut off the packaging sticker, the cutting plate 62 does not support the anti-grass cloth, and the anti-grass cloth falls off the cutting plate 62. When the cutting plate 62 rotates forward to reset, the turntables 61 on the left and right sides rotate forward to drive The left and right cams 71 rotate forward and reset, and the left and right cams 71 rotate forward and reset and disengage from the left and right contact racks 72. Due to the action of the four second springs 74, the left and right contact racks 72 move inward and reset and disengage from the left and right sliding rods 3. Due to the action of the reset springs 31, the left and right sliding rods 3 move inward and reset, so that the six pull wires 78 are relaxed. Due to the action of the six third springs 79, the six shifting blocks 77 move outward and reset. At the same time, the six shifting blocks 77 also drive the six pull wires 78 to move and reset. In this way, the packaging sticker can be used to package the anti-grass cloth more perfectly.

The receiving plate 82 is located below the front side of the cutting plate 62. When the packaged weed-proof cloth falls, the receiving plate 82 can guide the weed-proof cloth. A fourth spring 83 is symmetrically connected between the rear side of the bottom of the receiving plate 82 and the inner bottom of the mounting plate 81.

[0047] The buffer mechanism 9 includes a buffer block 91 and a fifth spring 92. Figure 1 and Fig.11 As shown, the inner ends of the left and right sliding rods 3 are slidably mounted with buffer blocks 91, which are used to enable the sliding rods 3 to better drive the anti-grass cloth to reverse, and the outer ends of the left and right buffer blocks 91 are respectively connected to the left and right sliding rods 3 with fifth springs 92.

[0048] When the packed weed-proof cloth falls from the cutting plate 62, the weed-proof cloth contacts the receiving plate 82, and the receiving plate 82 guides the weed-proof cloth. Due to the action of the fourth spring 83, the receiving plate 82 better buffers and guides the weed-proof cloth, and the weed-proof cloth on the receiving plate 82 rolls to the ground. In this way, the weed-proof cloth is prevented from falling violently to the ground and being damaged.

[0049] When the operator pulls the left and right sliding rods 3 to move outwards, the left and right sliding rods 3 move outwards and drive the fifth springs 92 on the left and right sides to move outwards. The fifth springs 92 on the left and right sides move outwards and drive the left and right buffer blocks 91 to move outwards. Then, when the operator moves a roll of grass-proof cloth between the left and right sliding rods 3, the left and right sliding rods 3 are released. Due to the action of the reset springs 31, the left and right sliding rods 3 move inwards and reset, and the left and right buffer blocks 91 move inwards and reset and are inserted into the grass-proof cloth. Due to the action of the fifth springs 92 on the left and right sides, the left and right buffer blocks 91 are better inserted into the center position of the grass-proof cloth, and the left and right buffer blocks 91 increase the friction with the grass-proof cloth. When the left and right sliding rods 3 reverse, the left and right sliding rods 3 reverse and drive the left and right buffer blocks 91 to reverse through the fifth springs 92 on the left and right sides. The reversal of the left and right buffer blocks 91 drives the grass-proof cloth to reverse. When the weed-proof cloth is packed, the left and right sliding rods 3 are pulled outward, and the left and right sliding rods 3 move outward, and the left and right buffer blocks 91 move outward through the left and right fifth springs 92, and the left and right buffer blocks 91 move outward and break away from the weed-proof cloth. In this way, the sliding rods 3 can better drive the weed-proof cloth to reverse for packing.
