Description
Technical Field
[0001] This utility model relates to a straw net weaving machine, and more particularly to an automatic conveying straw net weaving machine. Background Technology
[0002] Currently, woven grass nets are widely used, including for shielding and protecting military equipment. With the emergence of grass nets that can block electromagnetic waves, their use in the military field is becoming more and more widespread, and they can be seen everywhere in military bunkers, military vehicles, large-scale weapons, and individual soldier protection.
[0003] However, existing wave-absorbing grass net weaving technology usually relies on manual operation for sewing, splicing and edge locking. Manual operation is prone to problems such as uneven sewing and weak joints in the net body due to fatigue or differences in skills, which affects product quality; and the production efficiency is relatively low.
[0004] Therefore, it is necessary to design a straw net weaving machine that can efficiently and evenly sew straw nets and has an automatic conveying function. Utility Model Content
[0005] The technical solution is as follows: An automatic conveying straw net weaving machine includes a frame, a conveyor belt between the first and second ends of the frame, a rectangular electric slide rail and a gantry frame in the middle of the frame, the electric slide rail being located above the conveyor belt and inside the gantry frame, a sewing slider for sewing the woven net body being slidably mounted on the electric slide rail, and electric telescopic rods symmetrically arranged on both sides of the inner top wall of the gantry frame centered on the electric slide rail, the movable ends of the two electric telescopic rods being connected to a placement frame for placing the woven net body, the placement frame being located below the electric slide rail.
[0006] Furthermore, guide wheels are installed on both sides of the central part of the frame, centered on the conveyor belt, via several uprights. When the electric telescopic rod extends, the guide wheels are flush with the top plane of the placement frame.
[0007] Furthermore, the frame is symmetrically provided with arc-shaped plates on both sides of the conveyor belt and above the conveyor belt. A vertical block is installed on the inner side of one end of the arc-shaped plate. A groove is opened in the vertical block, and a pressure roller is slidably arranged in the groove. The pressure roller is located above the conveyor belt. An elastic element is provided between the inner wall of the top of the groove of the vertical block and the pressure roller.
[0008] Furthermore, an upper limit frame is installed inside the gantry frame, and the upper limit frame is located directly above the placement frame.
[0009] Furthermore, a rubber pad is provided at the bottom of the upper limit frame.
[0010] Furthermore, guide rollers are symmetrically arranged at both ends of the top of the frame, and the height of the guide rollers is lower than that of the conveyor belt.
[0011] The beneficial effects are as follows: 1. The mesh body is transported to the sewing area by the conveyor belt, which facilitates subsequent sewing; the mesh body is quickly fixed and released by the synergistic action of the electric telescopic rod and the upper limit frame. Combined with the sewing slider driven by the electric slide rail, sewing operations such as overlocking and splicing can be completed efficiently, thereby achieving efficient and uniform sewing of the mesh body and ensuring product consistency.
[0012] 2. The elastic pressure roller design can automatically adjust the downward pressure according to the thickness of the mesh body, ensuring that the mesh body is in close contact with the conveyor belt during the conveying process and preventing slippage or wrinkles.

Detailed Implementation
[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings.
[0020] Example: An automatic conveying straw net weaving machine, such as Figures 1-5As shown, the machine includes a frame 1, a conveyor belt 2, an electric slide rail 201, sewing sliders 3, a gantry frame 4, an electric telescopic rod 5, and a placement rack 6. The conveyor belt 2 is positioned between the left and right ends of the frame 1, forming a U-shape on the frame. A rectangular electric slide rail 201 and a gantry frame 4 are located in the middle of the frame 1. The electric slide rail 201 is positioned above the conveyor belt 2 and inside the gantry frame 4. Sewing sliders 3 are slidably mounted at each of the four right angles of the electric slide rail 201. During use, the four sewing sliders... 3. Move circumferentially along the electric slide rail 201 to sew the mesh body 100. Electric telescopic rods 5 are symmetrically arranged on both sides of the top inner wall of the gantry frame 4 with the electric slide rail 201 as the center. The movable ends of the two electric telescopic rods 5 are connected to a placement frame 6 for placing the mesh body 100. The placement frame 6 is located below the electric slide rail 201. When in use, the mesh body 100 on the placement frame 6 is lifted upward to the sewing area by the electric telescopic rods 5. The placement frame 6 passes through the inner hollow part of the electric slide rail 201.
[0021] like Figure 1 and Figure 2 As shown, guide wheels 601 are installed on both sides of the frame 1 with the conveyor belt 2 as the center. The guide wheels 601 are installed on the top of the uprights facing the placement frame 6. The uprights are installed on the frame 1. When the electric telescopic rod 5 extends, the guide wheels 601 are flush with the top plane of the placement frame 6. The guide wheels 601 reduce the frictional resistance of the mesh body 100 when it is transferred to the placement frame 6, reduce wear, and at the same time ensure that the mesh body 100 is laid flat, which is convenient for subsequent sewing.
[0022] like Figure 1 and Figure 4 As shown, arc-shaped plates 7 are symmetrically arranged on the loading side of the frame 1. The arc-shaped plates 7 are located on both sides of the conveyor belt 2 and above the conveyor belt 2. A vertical block 8 is installed on the inner side of one end of the arc-shaped plate 7. A sliding groove is opened in the vertical block 8. A pressure roller 10 is slidably arranged in the sliding groove. The pressure roller 10 is located above the conveyor belt 2. An elastic element 9 is arranged between the inner wall of the top of the sliding groove of the vertical block 8 and the pressure roller 10. The elastic element 9 is a compression spring. Through the cooperation of the spring element 9 and the pressure roller 10, the downward pressure is automatically adjusted according to the thickness of the mesh body 100, so as to ensure that the mesh body 100 is in close contact with the conveyor belt 2 during the conveying process and prevent slippage or wrinkles.
[0023] like Figure 1 and Figure 5As shown, an upper limit frame 11 is provided inside the gantry frame 4. The upper limit frame 11 is located directly above the placement frame 6. The upper limit frame 11 is adapted to the size of the placement frame 6. The upper limit frame 11 is used to limit the upward movement of the placement frame 6. A rubber pad 12 is provided at the bottom of the upper limit frame 11. The upper limit frame 11 limits the mesh body 100 on the placement frame 6, which facilitates uniform sewing. The placement frame 6 is driven to rise and fall by the electric telescopic rod 5. After the placement frame 6 passes through the hollow area inside the slide rail 201, it abuts against the upper limit frame 11. Through the limiting effect of the upper limit frame 11, the mesh body 100 is fixed on the placement frame 6. The loose edge part of the mesh body 100 located on the outer side of the placement frame is just placed on the electric slide rail 201. The electric slide rail 201 drives the sewing slider 3 to move horizontally along its surface, thereby completing the efficient edge locking, splicing and other sewing operations of the mesh body 100, improving production efficiency.
[0024] like Figure 1 As shown, guide rollers 13 are symmetrically arranged at both ends of the top of the frame 1. The height of the guide rollers 13 is lower than that of the conveyor belt 2. The completed mesh body 100 is guided from the conveyor belt 2 to the next process through the guide rollers 13.
[0025] In use, the mesh body 100 is placed on the surface of the conveyor belt 2 and driven to the sewing area. The pressure rollers 10 in the upright blocks 8 on both sides of the conveyor belt 2 are pressed down by elastic elements 9 (such as springs) to fix the mesh body 100 tightly against the conveyor belt 2 and prevent it from shifting during transport. The sliding design of the pressure rollers 10 can accommodate mesh bodies 100 of different thicknesses. The conveyor belt 2 continues to run, transporting the mesh body 100 towards the middle of the frame 1. The electric telescopic rod 5 extends downward, thereby causing the placement frame 6 to move down and be on the same horizontal plane as the conveyor belts 2 on both sides of the frame 1. At this time, since the guide rollers 601 are on the same horizontal plane as the placement frame 6, as the conveyor belt 2 continues to move, the two sides of the mesh body 100 pass through the guide rollers 601. The setting of the guide rollers 601 can reduce the coefficient of friction between the mesh body 100 and the placement frame 6, thereby ensuring that the mesh body 100 is properly secured. The mesh body 100 is conveyed to the placement rack 6, facilitating the next step of sewing the mesh body 100. Once the mesh body 100 is fully on the placement rack 6, the electric telescopic rod 5 retracts upward, thereby driving the placement rack 6 upward until the mesh body 100 is connected to the upper limit frame 11, thus effectively fixing the mesh body 100 on the placement rack 6. At this time, the electric slide rail 201 is energized, and the sewing slider 3 moves circumferentially along the surface of the electric slide rail 201, thereby achieving efficient sewing of the mesh body 100 (such as overlocking, splicing, etc.). After the mesh body 100 is sewn, the electric telescopic rod 5 extends downward, and the placement rack 6 moves down, thereby releasing the upper limit frame 11 from the mesh body 100. At this time, the worker can remove the sewn mesh body 100 from the placement rack 6 and convey it to the next process via the conveyor belt 2.
[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
