Description

Technical Field

[0001] The utility model relates to the technical field of knitting machines, and specifically relates to a knitting machine for the production of agricultural sunshade nets. Background Art

[0002] A sunshade net, also known as a shading net, is a new type of special protective covering material for agriculture, fishery, animal husbandry, wind prevention, soil covering, etc. After being covered in summer, it plays a role of blocking light, rain, moisturizing and cooling, and after being covered in winter and spring, it also has a certain effect of keeping warm and increasing humidity.

[0003] Currently, in the prior art, most knitting machines monitor the winding tension through a tension controller. However, the use of a tension controller is difficult to master and expensive. When used in an ordinary knitting machine for agricultural sunshade nets, both the labor cost and the equipment cost are too high. In view of this, we propose a knitting machine for the production of agricultural sunshade nets. Summary of the Invention

[0004] The main purpose of the utility model is to provide a knitting machine for the production of agricultural sunshade nets, which can solve the problems raised in the above technical background.

[0005] To achieve the above purpose, the utility model provides a knitting machine for the production of agricultural sunshade nets, including a device main body. A tension control device is arranged on the side of the device main body. The tension control device includes:

[0006] A limiting rod, the side of which is sleeved inside the upper cover plate. By setting the upper cover plate, the entry of external dust into the limiting ring can be significantly reduced, preventing the annular spring arranged inside the limiting ring from getting stuck, which would otherwise reduce the sensitivity of the tension control device. The bottom surface of the upper cover plate is fixedly connected to the upper surface of the limiting ring.

[0007] Preferably, the bottom surface of the limiting rod is fixedly connected to the upper surface of the controller, and the surface of the controller is rotatably connected to the inside of the limiting ring.

[0008] Preferably, one end of the annular spring is fixedly connected to the inside of the limiting ring, and the other end of the annular spring is fixedly connected to the surface of the moving block. The bottom surface of the limiting ring is fixedly connected to the upper surface of the limiting circle, and the bottom surface of the limiting circle is fixedly connected to the side of the device main body.

[0009] Preferably, the bottom surface of the moving block is fixedly connected to the upper surface of the connecting rod, the bottom surface of the connecting rod is rotatably connected to the side of the device main body, and a pressure roller is fixedly connected to the bottom surface of the connecting rod.

[0010] Preferably, the device body includes a device frame, a rotating motor is fixedly connected to the side surface of the device frame, an output shaft of the rotating motor penetrates through the side surface of the device frame and a main weaving frame, a moving rod is fixedly connected to the side surface of the device frame, and a secondary weaving frame is fixedly connected to the side surface of the moving rod.

[0011] Preferably, a winding bracket is fixedly connected to the upper surface of the device frame, a winding motor is fixedly connected to the side surface of the winding bracket, the winding motor is electrically connected to the controller, an output shaft of the winding motor penetrates through the side wall of the winding bracket and is fixedly connected to the side surface of a winding roller, and both sides of the winding roller are rotatably connected to the inside of the winding bracket.

[0012] The utility model provides a knitting machine for producing agricultural sunshade nets. It has the following beneficial effects:

[0013] (1). For the knitting machine for producing agricultural sunshade nets, by arranging the annular spring and the moving block, the winding force of the winding roller on the sunshade net can be detected, preventing the winding force of the winding roller on the sunshade net from being too large, which may cause the holes of the sunshade net to deform, resulting in deviations in subsequent device processing, thereby preventing the sunshade effect of the sunshade net from decreasing. Also, preventing the winding force of the winding roller on the sunshade net from being too small, which may cause the just woven sunshade net not to be stretched under force, preventing the internal mesh weaving structure from becoming loose, and thus preventing the arrangement of the inner mesh holes of the sunshade net from being chaotic, ensuring the quality of the sunshade net and having a relatively low production cost.

[0014] (2). For the knitting machine for producing agricultural sunshade nets, by arranging the pressing roller, the surface of the sunshade net can be compacted, preventing the surface of the just woven sunshade net from becoming loose, which may cause the internal mesh weaving to become chaotic and affect the continuous weaving of the subsequent sunshade net, resulting in a decrease in the production efficiency of the device.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Please refer to Figures 1 - 3 , the present utility model provides a knitting machine for the production of agricultural sunshade nets, including a device main body 1. The device main body 1 includes a device frame 101. A rotating motor 102 is fixedly connected to the side surface of the device frame 101. The output shaft of the rotating motor 102 penetrates the side surface of the device frame 101 and is connected to the main weaving frame 103. A moving rod 104 is fixedly connected to the side surface of the device frame 101. A sub-weaving frame 105 is fixedly connected to the side surface of the moving rod 104. A winding support 106 is fixedly connected to the upper surface of the device frame 101. A winding motor 107 is fixedly connected to the side surface of the winding support 106. The winding motor 107 is electrically connected to the controller 203. The output shaft of the winding motor 107 penetrates the side wall of the winding support 106 and is fixedly connected to the side surface of the winding roller 108. Both sides of the winding roller 108 are rotatably connected to the inside of the winding support 106. A tension control device 2 is arranged on the side surface of the device main body 1. The tension control device 2 includes:

[0023] The limiting rod 201 has its side sleeved inside the upper cover plate 202. By providing the upper cover plate 202, it can significantly reduce the entry of external dust into the limiting ring 204, preventing the annular spring 205 arranged inside the limiting ring 204 from getting stuck, which would otherwise cause a decrease in the sensitivity of the tension control device 2. The bottom surface of the upper cover plate 202 is fixedly connected to the upper surface of the limiting ring 204, the bottom surface of the limiting rod 201 is fixedly connected to the upper surface of the controller 203, the surface of the controller 203 is rotatably connected to the inside of the limiting ring 204, one end of the annular spring 205 is fixedly connected to the inside of the limiting ring 204, and the other end of the annular spring 205 is fixedly connected to the surface of the moving block 206. By providing the annular spring 205 and the moving block 206, the winding force of the winding roller 108 on the sunshade net can be detected, preventing the winding force of the winding roller 108 on the sunshade net from being too large, which would cause the holes of the sunshade net to deform, resulting in deviations during subsequent device processing, thus reducing the sunshade effect of the sunshade net. Also, it can prevent the winding force of the winding roller 108 on the sunshade net from being too small, which would cause the newly woven sunshade net not to be stretched under force, leading to loosening of the internal mesh weaving structure, thus causing chaos in the arrangement of the inner mesh holes of the sunshade net and affecting the quality of the sunshade net. The bottom surface of the limiting ring 204 is fixedly connected to the upper surface of the limiting circle 207, the bottom surface of the limiting circle 207 is fixedly connected to the side surface of the device main body 1, the bottom surface of the moving block 206 is fixedly connected to the upper surface of the connecting rod 208, the bottom surface of the connecting rod 208 is rotatably connected to the side surface of the device main body 1, and a pressing roller 209 is fixedly connected to the bottom surface of the connecting rod 208. By providing the pressing roller 209, the surface of the sunshade net can be compacted, preventing the surface of the just woven sunshade net from becoming loose, which would cause chaos in the internal mesh weaving and affect the continuous weaving of the subsequent sunshade net, thereby reducing the production efficiency of the device.

[0024] In the present utility model, during use, the rotation motor 102 is turned on. The rotation motor 102 drives the main weaving frame 103 to swing, causing the two strands of wire between the auxiliary weaving frame 105 and the main weaving frame 103 to become entangled and start weaving the net. One end of the net is fixed on the winding roller 108, and the winding motor 107 is turned on. The winding motor 107 continuously increases the winding tension until the sunshade net is pulled up, starting to push the pressing roller 209 to move upward. When the pressing roller 209 moves upward, the connecting rod 208 of the pressing roller 209 also moves upward, driving the moving block 206 to compress the annular spring 205. When the moving block 206 touches the pre-set limiting rod 201, the limiting rod 201 sends an electrical signal to the winding motor 107 through the controller 203, thereby fixing the winding tension and preventing the winding motor 107 from continuously increasing the winding tension and deforming the mesh holes of the sunshade net. By rotating the limiting rod 201, the tension of the winding motor 107 can be freely adjusted, thus completing the winding.

[0025] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields shall be included within the patent protection scope of the present utility model.
