The transmission mechanism comprises a transmission shaft 27, on both ends of which a third sprocket 22 is sleeved, and the third sprocket 22 is transmission-connected to the first sprocket 10 above the frame 1 through a transmission chain 15, and the first sprocket 10 is transmission-connected to the second sprocket 14 through a sprocket shaft 12. Above the frame 1, on the outer sides of the guide rails 4 on both sides, a trolley chain 18 transmission-connected to the second sprocket 14 is provided, and the trolley slide plates 16 are transmission-connected to the trolley chain 18.

[0022] The trolley slide 16 is provided with roller bearings 5, pins 6 and spacers 7 and is movably mounted on the guide rail 4, and an eccentric pin 17 is also provided on the trolley slide 16. The trolley slide 16 can be moved on the guide rail 4 by the arrangement of the roller bearings 5, pins 6 and spacers 7, and the trolley slide 16 can be adjusted by the arrangement of the eccentric pin 17, thereby ensuring that the trolley slide moves smoothly on the guide rail 4.

[0023] Wherein, the frame 1 is fixedly provided with a connecting seat 8 on both sides of the guide rail 4, the top of the connecting seat 8 is fixedly provided with a beam 9, and the top of the beam 9 is installed with a sprocket seat 11. Through the setting of the connecting seat 8, the support of the beam 9 can be achieved.

[0024] The sprocket shaft 12 is rotatably mounted on the sprocket seat 11 through a bearing 13, and the first sprocket 10 and the second sprocket 14 are respectively provided at both ends of the sprocket shaft 12, and the first sprocket 10 is located on the outside of the sprocket shaft 12. Through the arrangement of the sprocket shaft 12, the first sprocket 10 and the second sprocket 14 can rotate synchronously.

[0025] Among them, the beams 9 are all equipped with a reducer fixing plate 19, on which a reducer 20 is fixedly arranged, and the reducer 20 is connected to the driving motor 21 on the top thereof. The reducer 20 is rotatably provided with a transmission shaft 27, and the beams 9 on both sides are all equipped with a bearing fixing plate 23, and the bearing fixing plate 23 is provided with a bearing seat 24 adapted to the transmission shaft 27. The reducer 20 is driven by the driving motor 21, so that the transmission shaft 27 can be driven to rotate, so that the third sprockets 22 on both sides of the transmission shaft 27 can be synchronously rotated.

[0026] Among them, both ends of the transmission shaft 27 are provided with third sprockets 22, and the third sprockets 22 on both sides are respectively connected to the first sprockets 10 on both sides through the transmission chain 15. Through the setting of the transmission chain 15, the third sprockets 22 on both sides and the first sprocket 10 can be rotated synchronously.

[0027] Among them, the trolley chain 18 is provided with a chain pin seat 28, and the two ends of the trolley slide plate 16 are provided with a trolley pin seat 29. The chain pin seat 28 and the trolley pin seat 29 are provided with joint bearings 26, and the joint bearings 26 on both sides are connected by a support rod 25. Through the provision of the joint bearing 26 and the support rod 25, the chain pin seat 28 and the trolley pin seat 29 can be connected, so that the trolley chain 18 can drive the trolley slide plate 16 to reciprocate, so that the reciprocating motion of the trolley slide plate 16 can be used to efficiently complete the net laying action.

[0028] In the present invention, the trolley slides 16 on both sides can be fixedly connected by the trolley connecting frame 3, so that the net laying action can be efficiently completed by the reciprocating motion of the trolley slides 16 on both sides. It is worth noting that the specific structure and use of the net laying are the existing technologies currently disclosed on the market, which do not belong to the main technical problems to be solved in the present technical solution, so they are not described in detail in the present invention.

[0029] Furthermore, when the user needs to control the trolley connecting frame 3 to move, the reducer 20 can be driven by the driving motor 21, so that the transmission shaft 27 can be driven to rotate by the reducer 20. At this time, the third sprockets 22 on both sides of the transmission shaft 27 rotate synchronously with the transmission shaft 27, and the first sprocket 10 and the third sprocket 22 above the frame 1 can rotate synchronously through the setting of the transmission chain 15. Since the first sprocket 10 and the second sprocket 14 are both sleeved on the sprocket shaft 12, the second sprocket 14 also rotates synchronously with the first sprocket 10.

[0030] At this time, the trolley chain 18 can be driven by the second sprocket 14, and since the chain pin seat 28 and the trolley pin seat 29 are respectively provided on both sides of the trolley chain 18 and the trolley slide plate 16, and the chain pin seat 28 and the trolley pin seat 29 are both provided with joint bearings 26, and the joint bearings 26 are connected by the support rod 25. Therefore, the trolley slide plate 16 can be driven by the trolley chain 18, so that the trolley slide plate 16 can be located on the guide rail 4 and reciprocate.

[0031] In the utility model, the trolley slide plates 16 on both sides are located on the guide rails 4 and perform reciprocating motion, so the web laying action can be completed efficiently. By setting the driving motor 21 and the reducer 20, the first sprocket 10, the second sprocket 14 and the third sprocket 22 can be driven, so that the trolley chain 18 can be driven, and in conjunction with the setting of the support rod 25 and the joint bearing 26, the trolley slide plate 16 can be driven by the trolley chain 18 to perform reciprocating motion. This web laying method has good stability and high web laying efficiency, which not only improves production efficiency but also improves product quality.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
