Specific implementation manner

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-4 , a PE tarpaulin winding machine, including a centering assembly, a winding roller 12 and a support assembly. The centering assembly includes a base 1, a first motor 2, a left - hand and right - hand screw 3 and a bracket 4. A chute is provided on the base 1, and a left - hand and right - hand screw 3 is rotatably arranged in the chute. The output end of the first motor 2 penetrates through the base 1 and is connected to the left - hand and right - hand screw 3. The bracket 4 is L - shaped, and two sets of brackets 4 are provided. The lower part of the bracket 4 extends into the chute and is threadedly connected to the left - hand and right - hand screw 3;

[0025] Start the first motor 2. Since the first motor 2 uses a servo motor, the output can be accurately controlled. The output end of the first motor 2 drives the left - hand and right - hand screw 3 to rotate in the chute. Because the lower parts of the two sets of L - shaped brackets 4 are threadedly connected to the left - hand and right - hand screw 3, according to the principle of screw transmission, when the left - hand and right - hand screw 3 rotates, the two sets of brackets 4 will move relatively or away from each other in the chute. When winding PE tarpaulins of different widths, the distance between the two sets of brackets 4 can be accurately adjusted by controlling the rotation direction and angle of the first motor 2, so that the winding roller 12 is in a suitable position, realizing the centering function and ensuring that the PE tarpaulin always remains in the center position during the winding process, avoiding deviation and wrinkles;

[0026] The support assembly is provided on the support 4. The support assembly includes a bearing block 5, an auxiliary column 6, a bearing body 7, a baffle 8, a connecting member, and a support sleeve 9. The bearing block 5 is rotatably provided on the support 4 near one end of the base 1. Two groups of auxiliary columns 6 are further provided below the bearing block 5. The bearing body 7 is sleeved on the auxiliary column 6. A baffle 8 is further provided at one end of the outer ring of the bearing body 7 near the support 4. A connecting member is provided at one end of the baffle 8 away from the support 4. The support sleeve 9 is connected to the connecting member. Connecting pipes 10 are symmetrically provided on the left and right sides of the winding roller 12. The outer wall of the support sleeve 9 is in contact with the connecting pipe 10. A slot connected to the bearing block 5 is provided inside the connecting pipe 10. A second motor 11 is further provided on one group of the supports 4. The output end of the second motor 11 penetrates through the support 4 and is connected to the bearing block 5;

[0027] In the support assembly, the bearing block 5 is rotatably provided on the support 4 near one end of the base 1. The two groups of auxiliary columns 6 below the bearing block 5 enhance the stability of the support. The first reinforcing rib 17 below the auxiliary column 6 further ensures the strength of the auxiliary column 6. The bearing body 7 is sleeved on the auxiliary column 6. The baffle 8 on its outer ring is connected to the support sleeve 9 through a connecting member. For the connecting pipes 10 on the left and right sides of the winding roller 12, their outer walls are in contact with the support sleeve 9, and the inner slots are connected to the bearing block 5, forming a stable support structure to ensure that the winding roller 12 remains stable when winding the tarpaulin.

[0028] The connecting member includes a positioning block 13, an elastic member, and a clamping block 14. The support sleeve 9 is provided with a slot adapted to the positioning block 13. An activity slot is further provided at one end of the positioning block 13 away from the auxiliary column 6. Both ends of the elastic member are respectively connected to the inner wall of the activity slot and the clamping block 14. The support sleeve 9 is further provided with a clamping hole adapted to the clamping block 14. The elastic member includes a spring 15 and a telescopic rod 16. The spring 15 is sleeved on the telescopic rod 16. Both ends of the spring 15 and the telescopic rod 16 are respectively connected to the inner wall of the activity slot and the clamping block 14. When installing the support sleeve 9, align the slot on the support sleeve 9 with the positioning block 13 and insert it. As the support sleeve 9 is inserted, the clamping block 14 is squeezed by the support sleeve 9 and contracts into the activity slot under the action of the elastic member (spring 15 and telescopic rod 16). When the clamping block 14 moves to the position of the clamping hole on the support sleeve 9, the spring 15 rebounds, and the clamping block 14 is clamped into the clamping hole to complete the installation of the support sleeve 9. When disassembling, press the clamping block 14 to overcome the elastic force of the spring 15, so that the clamping block 14 is disengaged from the clamping hole, and the support sleeve 9 can be removed from the positioning block 13, realizing the convenient disassembly and assembly of the winding roller 12, so as to facilitate disassembly and assembly when the support sleeve 9 is worn and needs to be replaced.

[0029] Start the second motor 11. Similarly, since the second motor 11 is a servo motor, the rotation speed and rotation angle can be precisely controlled. The output end of the second motor 11 drives the bearing seat 5 to rotate, and then drives the winding roller 12 to rotate. One end of the PE tarpaulin is fixed on the winding roller 12. During the rotation of the winding roller 12, the tarpaulin is gradually wound around its surface. During the winding process, due to the stable support of the support assembly and the precise centering of the centering assembly, the tarpaulin can be wound tightly and neatly on the winding roller 12, ensuring the flatness and quality of the winding. At the same time, the second reinforcing rib 18 provided at the end of the bracket 4 away from the center of the base 1 enhances the strength of the bracket 4, enabling it to better withstand the acting force during the winding process.
