Description

Technical Field

[0001] This utility model relates to the field of straw baling net technology, and in particular to a novel straw baling net processing and winding mechanism. Background Technology

[0002] Hay baling nets are a type of knitted material made of plastic yarn produced by knitting machines. They are mostly used to bundle straw and hay. During the production of hay baling nets, they need to be wound up onto the winding rollers by a hay baling net winding mechanism.

[0003] For example, the authorized announcement number "CN221587461U" is named a baling net processing and winding mechanism. By passing the baling net over the adjusting roller, the height of the adjusting roller can be adjusted, thereby adjusting the tension of the baling net and improving the winding effect of the baling net.

[0004] The above-mentioned and existing technologies have the following drawbacks: the winding mechanism can only wind up one bundle of straw net at a time, which is inefficient; the upper and lower rollers are only adjusted in distance by a second electric telescopic rod, which is not very precise. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a novel straw bundling and winding mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A novel straw baling net processing and winding mechanism is designed, comprising multiple support legs, with a U-shaped block at the upper end of each support leg.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-5 A novel straw baling and winding mechanism includes multiple support legs 1, with a U-shaped block 2 at the top of each support leg 1. Two symmetrical first mounting plates 3 are located on the center of the upper surface of the U-shaped block 2. Two winding rollers 4 are positioned between the two first mounting plates 3. Two first rotating shafts 5 are rotatably connected to the opposing surfaces of the two first mounting plates 3. Both first rotating shafts 5 in the same forward / backward direction are detachably connected to the winding rollers 4 via locking devices. The two first rotating shafts 5 on the same side pass through the first mounting plates 3 and are equipped with a transmission device. An adjustment device is located in the center of the lower inner wall of the U-shaped block 2. The left and right sides of the character-shaped block 2 are equipped with flattening devices. The flattening devices include two second mounting plates 6 fixed on the upper surface of the character-shaped block 2. The two second mounting plates 6 are rotatably connected to a lower rotating roller 8 through a second rotating shaft 7. An upper rotating roller 9 is provided above the lower rotating roller 8. A first cylinder 10 is provided on the lower inner wall of the character-shaped block 2. A first telescopic rod 11 is provided on the upper surface of the first cylinder 10. A first U-shaped frame 12 is provided at the upper end of the first telescopic rod 11. The inner walls on both sides of the first U-shaped frame 12 are rotatably connected to the upper rotating roller 9 through a third rotating shaft 13. A triggering device is provided between the first U-shaped frame 12 and the second mounting plate 6.

[0016] The transmission device includes two meshing gears 14, which are fixedly connected to the corresponding first rotating shafts 5. An L-shaped plate 15 is provided on one side of the first mounting plate 3, a motor 16 is provided on one side of the L-shaped plate 15, and an output shaft 17 is provided on one side of the motor 16. The output shaft 17 is fixedly connected to one of the two gears 14.

[0017] The locking device includes two auxiliary shafts 18, which are disposed on both sides of the take-up roller 4. Square grooves 19 are formed on the opposing surfaces of the two auxiliary shafts 18, and notches 20 are formed on both sides of each auxiliary shaft 18. Rectangular blocks 21 are formed on the facing surfaces of the two first rotating shafts 5. The rectangular blocks 21 extend into the inner square grooves 19. Bolts 22 are installed inside the notches 20, with one end of each bolt passing through the square groove 19 and the rectangular block 21 and threadedly connected to a first nut 23. The adjusting device includes a second cylinder 24, a second telescopic rod 25 on the upper surface of the second cylinder 24, a connecting column 26 on the upper surface of the second telescopic rod 25, and a second U-shaped frame 27 at both ends of the connecting column 26. The second U-shaped frame 27 is rotatably connected to an adjusting roller 29 through a fourth rotating shaft 28.

[0018] The triggering device includes a first positioning block 30 and a second positioning block 31. The first positioning block 30 is disposed on one side surface of the first U-shaped frame 12, and the second positioning block 31 is disposed on one side surface of the second mounting plate 6. A trigger block 32 is provided on the lower surface of the first positioning block 30, and a limit switch 33 is provided on the upper surface of the second positioning block 31.

[0019] The second mounting plate 6 has a strip-shaped hole 34 on its surface. The second positioning block 31 has a lead screw 35 on the side surface near the strip-shaped hole 34. The lead screw 35 passes through the strip-shaped hole 34 and is threadedly connected to a second nut 36. By loosening the second nut 36, the lead screw 35 can be moved up and down in the strip-shaped hole 34, which facilitates the adjustment of the distance between the trigger block 32 and the limit switch 33.

[0020] The working principle and usage process of this utility model are as follows: During use, the locking device is used to fix the first take-up roller 4 onto the corresponding two first rotating shafts 5 by fitting the square grooves 19 on the auxiliary shafts 18 at both ends of the first take-up roller 4 onto the rectangular block 21 and connecting them with bolts 22 and first nuts 23. Then, the second take-up roller 4 is installed onto the corresponding two first rotating shafts 5 in the same manner. Next, the baling net on one side of the take-up mechanism is installed, and one end of the baling net is passed between the lower rotating roller 8 and the upper rotating roller 9. The first cylinder 10 is activated, shortening the first telescopic rod 11, thereby causing the first U-shaped frame 12 to move downwards. This is triggered by the triggering device, which then triggers the lower trigger block 32. Pressing the limit switch 33 stops the first cylinder 10, pressing the upper rotating roller 9 onto the surface of the baling net. Then, the baling net is passed over the adjusting roller 29 and finally wound onto the take-up roller 4. Similarly, following the above operation, the baling net on the other side of this take-up mechanism is installed. Through the adjusting device, the second cylinder 24 is started, causing the second telescopic rod 25 to extend, thereby driving the adjusting roller 29 to rise and press against the baling net to prevent it from loosening and to make it tightly wound onto the take-up roller 4. Through the transmission device, the motor 16 is started, causing the output shaft 17 to rotate. One gear 14 rotates, driving another gear 14 to rotate, thereby causing the two take-up rollers 4 to rotate for take-up.

[0021] In summary, this winding mechanism can wind up two bundles of straw netting at a time, which is highly efficient. At the same time, by activating the first cylinder 10, the upper roller 9 moves. By using the triggering device, the trigger block 32 presses down the limit switch 33 to stop the first cylinder 10, which can limit the distance between the lower roller 8 and the upper roller 9, and the adjustment accuracy is very high.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
