Description

Technical Field

[0001] The invention relates to the technical field of sunshade net edge pressing, in particular to a sunshade net edge pressing device. Background Art

[0002] Sunshade net, also known as shading net, is a new type of protective covering material for agriculture, fishery, animal husbandry, windbreak, soil covering, etc. that has been promoted in the past 10 years. It can block light, rain, moisturize and cool down after covering in summer. It can also keep warm and increase humidity after covering in winter and spring.

[0003] During processing, existing sunshade nets need to be cut by a pressing mechanism and then the edges need to be hot-pressed to shape them to prevent thread ends from existing on the edges during subsequent use. However, since the sunshade net is woven from multiple strands of wire and has a large overall elasticity, it is easy to over-stretch during stretching and cutting, resulting in deformation of the cut sunshade net and poor quality of the finished product. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a sunshade net edge pressing device to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a sunshade net edge pressing device, comprising a frame and a conveying roller group rotating above the frame for conveying the sunshade net, and the side edges of the frame are respectively provided with an edge pressing mechanism for pressing the sunshade net and a traction mechanism for traction of the sunshade net;

[0006] A guide roller for guiding the sunshade net is rotatably arranged at the upper right corner of the frame, and the sunshade net is bent 90 degrees on the frame and transported vertically downward;

[0007] The pressing mechanism comprises a fixed plate and two receiving plates fixed to the side of the frame, the surface of the fixed plate is slidably connected with a pressing plate driven by a power mechanism to press the sunshade net and a cutter to cut the sunshade net, the surface of the cutter is fixedly connected with a push plate, the surfaces of the fixed plate located above and below the cutter are slidably connected with sliding blocks through sliding grooves, one side of the two sliding blocks is fixedly connected with a hot pressing plate for hot pressing the sunshade net, and the left side of the push plate is fixedly connected with a return spring. When in use, the sunshade net is transported by the conveying roller group and guided by the guide roller, and then falls vertically downward, and then is located between the traction roller and the receiving roller. At this time, the concave surface of the traction roller faces the sunshade net, and then the traction roller is driven to rotate by the motor. The traction roller rotates to the concave surface downward. At this time, the surface of the traction roller rubs with the sunshade net through friction The friction force pulls the sunshade net downward, making it in a downward stretched state. Then the pressing plate is started to block the top of the sunshade net, and then the cutter is driven to cut the sunshade net. The movement of the cutter drives the push plate to move, and drives the reset spring to move first against the surface of the sliding block, and then drives the sliding block to slide in the sliding groove, driving the hot pressing plate to squeeze on both sides of the sunshade net, and then the cutter feeds, the reset spring continues to compress, and then the cutter cuts the sunshade net, and the hot pressing plate is used to hot press the cut sides. After processing, the cutter and the pressing plate are retracted, and under the action of gravity, the cut sunshade net falls naturally to complete the edge pressing operation. Gravity can be used to quickly transport, cut and press the sunshade net. The structure is simple, positioning is convenient, it will not cause excessive pulling on the sunshade net, and the transportation is effective.

[0008] As a further solution of the present invention: a cutting groove coinciding with the movement trajectory of the cutter is provided between the two receiving plates, through which the cutter is embedded in the cutting groove for effective cutting, and the hot pressing plate is received by the receiving plate to effectively perform hot pressing on both sides of the sunshade net to shape it.

[0009] As a further solution of the present invention: a heating wire is built into the inner cavity of the hot pressing plate, and the temperature of the hot pressing plate is controlled by heating the heating wire to heat and press the side of the sunshade net to form it.

[0010] As a further solution of the present invention: when the cutter extends to four-fifths of the two heat pressing plates, the reset spring abuts against the side of the sliding block, the sunshade net can be pressed up and down by the heat pressing plates in advance, and then the cutter cuts the middle part, which can prevent the sunshade net from falling after cutting due to gravity. The movement of the cutter can achieve the functions of positioning and cutting at the same time.

[0011] As a further solution of the present invention: the receiving plate and the cutter are respectively arranged on both sides of the sunshade net. Under the action of gravity, the sunshade net automatically hangs down and is located between the receiving plate and the cutter when being transported downward, and can be automatically positioned under the action of gravity.

[0012] As a further solution of the present invention: the traction mechanism includes a receiving roller and a traction roller which are arranged on the side of the frame and are driven to rotate by a motor. The receiving roller and the traction roller are respectively arranged on both sides of the sunshade net. A concave surface is opened on one side of the traction roller. When in use, the sunshade net is transported by the conveying roller group and guided by the guide roller and then falls vertically downward. Then it is located between the traction roller and the receiving roller. At this time, the concave surface of the traction roller faces the sunshade net. The traction roller is then driven to rotate by the motor. The traction roller rotates to the concave surface facing downward. At this time, the surface of the traction roller rubs against the sunshade net, and the sunshade net is pulled downward by the friction force, so that it is in a downward stretched state. It is easy to straighten and has a simple structure. When traction is not needed, it only needs to face the concave surface of the traction roller toward the sunshade net, and it does not interfere with the automatic falling of the sunshade net under gravity.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In the present invention, under the action of gravity, the cut sunshade net falls naturally to complete the edge pressing operation. The sunshade net can be quickly transported, cut and pressed by gravity. The structure is simple, positioning is convenient, no excessive pulling is caused to the sunshade net, and the transportation is effective.

[0015] 2. The present invention pulls the sunshade net downward by friction force, so that it is in a downward stretched state. It is easy to straighten and has a simple structure. When traction is not needed, it only needs to turn the concave surface of the traction roller toward the sunshade net, and it does not interfere with the automatic falling of the sunshade net under gravity.

The surface of the cutter 10 is fixedly connected with a push plate 9. The surfaces of the fixed plate 4 located above and below the cutter 10 are slidably connected with sliding blocks 7 through sliding grooves 6. One side of the two sliding blocks 7 is fixedly connected with a hot pressing plate 8 for hot pressing the sunshade net 3. The left side of the push plate 9 is fixedly connected with a return spring 11. When in use, the sunshade net 3 is conveyed by the conveying roller group 2 and falls vertically downward after being guided by the guide roller, and then is located between the traction roller 13 and the receiving roller 15. At this time, the concave surface 14 of the traction roller 13 faces the sunshade net 3, and then the traction roller 13 is driven by the motor to rotate. The traction roller 13 rotates until the concave surface 14 faces downward. At this time, the surface of the traction roller 13 rubs against the sunshade net 3. The sunshade net 3 is pulled downward by friction, so that it is in a downwardly stretched state. At this time, the pressing plate 5 is started to block the top of the sunshade net 3, and then the cutter 10 is driven to cut the sunshade net 3. The movement of the cutter 10 drives the push plate 9 to move, and drives the return spring 11 to move to first abut against the surface of the sliding block 7, and then drives the sliding block 7 to slide in the sliding groove 6, driving the hot pressing plate 8 to squeeze on both sides of the sunshade net 3, and then the cutter 10 is fed, the return spring 11 is continuously compressed, and then the cutter 10 cuts off the sunshade net 3, and the hot pressing plate 8 is used to hot-press the cut sides. After the processing is completed, the cutter 10 and the pressing plate 5 are retracted, and under the action of gravity, the cut sunshade net 3 falls naturally to complete the edge pressing operation. Gravity can be used to quickly transport, cut and press the sunshade net 3. The structure is simple and positioning is convenient. It will not cause excessive pulling on the sunshade net 3, and the transportation is effective.

Through the cutting groove 16, the cutter 10 is embedded in the cutting groove 16 for effective cutting, and the hot pressing plate 8 is received by the receiving plate 12 to effectively perform hot pressing on both sides of the sunshade net 3 to shape it.

[0025] The inner cavity of the hot pressing plate 8 is built with a heating wire, and the temperature of the hot pressing plate 8 is controlled by heating the heating wire to heat and press the side of the sunshade net 3 to form it.

[0026] When the cutter 10 extends to four-fifths of the two heat pressing plates 8, the reset spring 11 abuts against the side of the sliding block 7, and the sunshade net 3 can be pressed up and down by the heat pressing plates 8 in advance, and then the cutter 10 cuts the middle part, which can prevent the sunshade net 3 from falling after cutting under the action of gravity. The movement of the cutter 10 can achieve the functions of positioning and cutting at the same time.

[0027] The receiving plate 12 and the cutter 10 are respectively arranged on both sides of the sunshade net 3. Under the action of gravity, the sunshade net 3 automatically hangs down and is located between the receiving plate 12 and the cutter 10 when being transported downward, and can be automatically positioned under the action of gravity.

[0028] The traction mechanism includes a receiving roller 15 and a traction roller 13 which are arranged on the side of the frame 1 and are driven to rotate by a motor. The receiving roller 15 and the traction roller 13 are respectively arranged on both sides of the sunshade net 3. A concave surface 14 is opened on one side of the traction roller 13. When in use, the sunshade net 3 is transported by the conveying roller group 2 and guided by the guide roller and then falls vertically downward. Then it is located between the traction roller 13 and the receiving roller 15. At this time, the concave surface 14 of the traction roller 13 faces the sunshade net 3. Then the traction roller 13 is driven to rotate by the motor. The traction roller 13 rotates until the concave surface 14 faces downward. At this time, the surface of the traction roller 13 rubs against the sunshade net 3, and the sunshade net 3 is pulled downward by the friction force, so that it is in a downward stretched state. It is convenient to straighten and has a simple structure. When traction is not needed, it is only necessary to turn the concave surface 14 of the traction roller 13 toward the sunshade net 3, and it does not interfere with the automatic falling of the sunshade net 3 under gravity.
