Description

Technical Field

[0001] The invention relates to a net weaving machine, in particular to a winding mechanism of the net weaving machine. Background Art

[0002] The mesh weaving machine is used to weave the mesh, which includes warp and weft. The weft is interlaced between adjacent warp to form a triangular mesh. At present, the mesh produced by the mesh weaving machine generally needs to be rewound by a rewinding machine after winding due to poor winding quality. The operation procedure is cumbersome and complicated, requiring workers to perform repetitive labor, which is labor-intensive. The main reasons for the poor winding quality are: when winding, the warp of the mesh will be wound on the same position of the winding shaft. When the winding reaches a certain number of turns, the winding diameter at the location of the warp will be significantly larger than the winding diameter at other locations, resulting in the mesh coil being partially tight and partially loose, and the tight area will be close to the loose area. The final result is uneven winding, which brings inconvenience to subsequent use. Summary of the invention

[0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a winding mechanism for a net weaving machine with good winding quality, compact and flat netting material after winding, improved production efficiency and reduced labor intensity of workers.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: the winding mechanism of the net weaving machine includes a movable bracket, a fixed bracket and a winding drum and a pressure roller rotatably arranged on the movable bracket, the rotation of the winding drum is driven by a winding motor, the pressure roller is arranged above the winding drum, and the pressure roller is rotatably arranged on the crank. During the winding operation, the pressure roller presses the paper roll onto the winding drum, and both ends of the paper roll are supported by plugs, which are connected to one end of a swing arm, and the other end of the swing arm can be adjusted left and right and is arranged on the swing arm shaft and locked by a screw, the swing arm shaft can be rotatably arranged on the movable bracket, and the movable bracket can be moved left and right and is arranged on the movable bracket, and the crank is arranged on the fixed bracket to swing up and down, and the crank is connected to the crank cylinder.

[0005] The shaft end of the winding drum is connected to the worm, and the worm wheel meshing with the worm is fixed on the vertical shaft. The vertical shaft is rotatably arranged on one side of the movable bracket. The lower shaft end of the vertical shaft is connected to the cam, and the fixed bracket is provided with a bearing rolling along the circumference of the cam.

[0006] The winding drum and the pressure roller are provided with two identical upper and lower groups.

[0007] A heating roller is arranged on the fixed bracket, and wire grooves arranged in sequence at certain intervals are arranged on the heating roller.

[0008] With the structure of the present invention, the woven mesh after weaving can be passed through a heating roller to position the warp threads on the mesh or to shape them at high temperature, and then be rolled up on a paper drum. The paper drum is in contact with the winding drum, so that the winding drum drives the paper drum to rotate. At the same time, the paper drum is mounted on a movable bracket and swings back and forth, so that the warp threads will not be wound around the same position, thereby making the mesh wire flat and compact after being rolled up. This not only reduces the rewinding process, but also improves production efficiency.

[0014] The present invention is specifically described below by way of examples.

[0015] like Figure 1-Figure 3 As shown, the present invention discloses a winding mechanism of a net weaving machine, comprising a movable bracket 2, a fixed bracket 1, a winding drum 3, a pressure roller 4 and a paper roll 6 rotatably arranged on the movable bracket 2, the rotation of the winding drum 3 is driven by a winding motor, the pressure roller 4 is arranged above the winding drum 3, the pressure roller 4 is rotatably arranged on a crank 5, the middle position of the crank 5 is rotatably installed on the movable bracket 2, during winding operation, the pressure roller 4 presses the paper roll 6 on the winding drum 3, both ends of the paper roll 6 are supported by a plug 7, the plug 7 is connected to one end of a swing arm 8, the other end of the swing arm 8 can be adjusted left and right and is arranged on a swing arm shaft 80 and locked by a screw, the swing arm shaft 80 can be rotatably arranged on the movable bracket 2, the movable bracket 2 can be movably arranged left and right on the fixed bracket 1, the crank 5 is arranged to swing up and down on the fixed bracket 1, and the crank 5 is connected to a crank cylinder 9. In the above structure, the paper tube, pressure roller and winding drum swing with the movable bracket, so that the paper tube moves along its axial direction. At the same time, under the pressure of the pressure roller, the warp overlap is less likely to occur when the woven mesh is rolled on the paper tube, making the rolled woven mesh smoother.

[0016] The shaft end of the winding drum 3 is connected to the worm 31, and the worm wheel 32 that is in driving engagement with the worm 31 is fixed on the vertical shaft 9. The vertical shaft 9 is rotatably arranged on one side of the mobile bracket 2. The lower shaft end of the vertical shaft 9 is connected to the cam 10. The fixed bracket 1 is provided with a bearing 20 that rolls along the circumference of the cam. At the same time, a roller is arranged at the lower end of the mobile bracket 2, and a guide groove corresponding to the roller is arranged on the fixed bracket. Through such a transmission method, the paper tube 6 can swing back and forth with the rotation of the winding drum 3, so as to prevent the warp from being wound and received at the same position, and such a transmission structure is reliable and stable.

[0017] The winding roller 3 and the pressure roller 4 are provided with two identical upper and lower groups. The winding rollers 3 in the two groups can be driven by belts, and each group is provided with corresponding guide rollers 30 and heating rollers 40, which are arranged on a fixed bracket. Figure 4 As shown, the heating roller 40 is provided with wire grooves 401 arranged in sequence at certain intervals. The warp threads on the woven mesh are positioned and conveyed through the wire grooves 401, so that the woven mesh can be rolled up more smoothly. At the same time, the parallel weaving machines can be used together to improve production efficiency and reduce the occupied area. After the heating roller is powered on and heated, it can be high-temperature shaped along with the warp threads of the woven mesh passing through, so that the spacing between the warp threads can be reduced. At this time, it is only necessary to replace the heating roller with a wire groove spacing smaller than the spacing between the warp threads of the woven mesh. Of course, the spacing between the warp threads of the woven mesh can also be enlarged by the same method. It should be noted here that the high-temperature roller surface temperature of the heating roller is between 120°C and 130°C, and the corresponding woven mesh conveying speed is between 85m / min and 100m / min.

[0018] In the above structure, the reduction of the interval between the warps can increase the length of the wefts, improve the bearing capacity of the wefts, and avoid changes in the length and width of the woven net during use. It is especially used for the soft base net for cultivating tulip seeds. The tulip bulbs are mixed with mud and cultivated between two soft base nets. After the bulbs grow larger, the wefts have a larger length to support them, so they will not pull the warps on the soft base net, so that the overall length and width of the soft base net will not change, so that the bulbs have a better growth space.

[0019] The outer wall of the plug 7 is provided with a ring-shaped limiting step 71, through which the plug 7 can abut against the end of the paper tube 6, so that the fit between the plug 7 and the paper tube 6 is more reliable, and a "T"-shaped rotating shaft 50 is inserted in the inner hole of the plug 7, and the shaft portion of the rotating shaft 50 is inserted into the end of the swing arm and fixedly connected by bolts, thereby realizing the rotatable installation of the plug 7.

[0020] Through the above technical scheme, the woven mesh after weaving can pass through the heating roller 40 to position the warp threads on the weaving or high-temperature fix them, and then pass through the guide roller 30 to enter the gap between the paper drum 6 and the pressure roller 4 to be wound on the paper drum 6. Since the paper drum 6 is in contact with the winding roller, the winding roller drives the paper drum 6 to rotate. At the same time, the paper drum 6 is installed on the movable bracket to swing back and forth, so that the warp threads will not be wound around the same position, so that the mesh line is flat and compact after winding, which not only reduces the rewinding process but also improves production efficiency.
