Description

Technical Field

[0001] This invention relates to the field of close-mesh safety net processing, specifically to a close-mesh safety net processing edge-wrapping device. Background Technology

[0002] Close-mesh safety netting is a safety protection device used on construction sites. It is usually made of high-strength polyester fiber or nylon material and can effectively prevent objects from falling, protecting workers and pedestrians on the construction site from injury. It can also act as a barrier to block bricks, tools or other materials falling from heights.

[0003] A close-mesh safety net typically consists of a net body, eyelet loops, edge ropes, and additional tie ropes. The edge ropes are installed on the four sides of the net body and are wrapped around the net body by rolling it up. The folded net body is then sewn together. The edge ropes are used to secure the safety net, making it easy to install and remove.

[0004] In the current production process of close-mesh safety nets, the installation of edge ropes is usually done manually. However, manual labor often presents the following unresolved problems: 1. Workers find it difficult to adjust the relative position of the edge ropes to the net while folding it. If the relative position of the edge ropes to the net is not fixed, it is very likely that the edge ropes will slip relative to the net, or even bend, causing the sewing needle to pass through the edge ropes during sewing, which greatly affects the quality of the finished product; 2. It is difficult to accurately control the length of the folded net manually, and it is also difficult to ensure that the length of the folded part of the entire net is consistent. If the length of the folded part of the net cannot be controlled, it may cause the edge of the finished product to be crooked; 3. Manual production efficiency is very low. The relative position of the edge ropes to the net needs to be adjusted before sewing can begin, which greatly affects efficiency. Summary of the Invention

[0030] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, they shall be performed in accordance with the techniques or conditions described in the literature in the art or in accordance with the product manual.

[0031] See Figure 1 A close-mesh safety net processing and edging device includes a main mounting frame 1, the main body of which is C-shaped. A clamping component 2 is provided on the main mounting frame 1. An adjusting component 3 is provided on the main mounting frame 1 to the right of the clamping component 2. An edge-rolling component 4 is provided to the right of the adjusting component 3. Two positioning wheels 11 are arranged side by side on the main mounting frame 1 to the left of the clamping component 2. A sewing machine 5 is slidably connected between the two positioning wheels 11 on the main mounting frame 1. The axle of the positioning wheel 11 is slidably connected to the main mounting frame 1. A pin hole structure is provided at the sliding connection between the two. A pin is provided in the pin hole. The pin hole on the main mounting frame 1 is inserted into the axle of the positioning wheel 11 through the pin, thereby adjusting the front-to-back relative position of the positioning wheel 11 with respect to the main mounting frame 1.

[0032] The hemming assembly 4 of this invention can fold and roll the net body at equal intervals through the guide outer cylinder 41, solving the problem that it is difficult to accurately control the length of the folded net body manually. At the same time as folding, the guide inner cylinder 42 can roll the edge rope inside it, and the fixing wheel 44 is used to prevent the net body from slipping from the guide inner cylinder 42 and the guide outer cylinder 41. The adjustment assembly 3 of this invention can straighten the net body through the pulling member 32 to prevent the net body from being sewn fixed after folding. It can also straighten the edge rope to prevent the edge rope from bending and causing the sewing needle to pass through the edge rope, which greatly improves the product qualification rate. The clamping assembly 2 of this invention can eliminate the gap between the folded part of the net body and the edge rope through the clamping block 24, which effectively solves the problem of relative sliding between the edge rope and the net body affecting product quality. The various components of this invention work together, and the manual only needs to do the preparatory work to realize the automated hemming process of the close-mesh safety net. Compared with manual hemming, it improves product quality and greatly improves efficiency.

[0033] It should be noted that the sewing machine 5 provided in this invention is existing technology, which can reliably sew the already rolled and folded net body. The sewn net body is then rolled up by an existing winding mechanism. The spacing of the sewing of the net body is controlled by controlling the winding speed of the winding mechanism and the sewing speed of the sewing machine 5.

[0034] See Figure 1 , Figures 5-7 The rolled edge assembly 4 includes a guide outer cylinder 41 fixedly mounted on the main mounting frame 1, and a guide inner cylinder 42 provided inside the guide outer cylinder 41. The guide inner cylinder 42 is fixedly connected to the main mounting frame 1 through a connecting rod 43. A groove is opened on the front side of the guide outer cylinder 41 and the guide inner cylinder 42 along the front-rear direction. A fixed wheel 44 is rotatably connected in the groove of both the guide outer cylinder 41 and the guide inner cylinder 42. The fixed wheel 44 has a spike-like structure on its arc surface.

[0035] The edge-rolling assembly 4 of this invention can roll and fold the net body at equal intervals through the outer guide cylinder 41, which solves the problem that it is difficult for humans to accurately control the length of the folded net body. At the same time as rolling and folding, the inner guide cylinder 42 can roll the edge rope into it, and the fixed wheel 44 is used to prevent the net body from slipping from between the inner guide cylinder 42 and the outer guide cylinder 41.

[0036] Specifically, the worker first rolls up the safety net along the inner wall of the guide outer cylinder 41 and passes it through the gap between the guide outer cylinder 41 and the guide inner cylinder 42. The fixed wheel 44 prevents the net from slipping between the two. Then, the side rope passes through the inside of the guide inner cylinder 42, and then the net passes through other subsequent components. After the preparation work is completed, the external drive wheel provides power to the net and pulls it backward. Under the action of the inner wall of the guide outer cylinder 41, the net begins to automatically curl. At the same time, the fixed wheel 44 rotates, determining the length of the net to be curled without affecting the backward movement of the net, so as to prevent it from falling and affecting the processing.

[0037] See Figure 1 , Figure 4 The adjustment component 3 includes a straightening component 31 located on the right side of the clamping component 2. A pulling component 32 is provided on the right side of the straightening component 31. The straightening component 31 includes a mounting plate 311 fixedly mounted on the main mounting frame 1. A crank 312 is rotatably connected to the mounting plate 311. A rocker arm 313 is rotatably connected to the mounting plate 311 and located to the left of the crank 312. A second motor 314 is fixedly connected to the mounting plate 311 and located behind the crank 312. The output shaft of the second motor 314 passes through the mounting plate 311 and is fixedly connected to the crank 312. The end of the rocker arm 313 away from the mounting plate 311 is connected to the crank 312 via a connecting rod 315. The connecting rod 315 is rotatably connected to both the rocker arm 313 and the crank 312. A straightening block 316 is rotatably connected to the connecting rod 315 and located to the right of the rocker arm 313. The straightening block 316 is an elastic telescopic structure.

[0038] See Figure 1 The pulling component 32 includes a pressing cylinder 321 fixedly mounted on the main mounting frame 1. The pressing cylinder 321 is fixedly connected to a telescopic sleeve 322. A connecting hinge 323 is hinged to the side of the telescopic sleeve 322. A pulling block 324 is hinged to the end of the connecting hinge 323 away from the telescopic sleeve 322. A guide rod 325 is fixedly connected to the rear side of the pulling block 324. The guide rod 325 passes through the main mounting frame 1 rearward and is used to ensure that only the pulling block 324 moves back and forth when the pressing cylinder 321 extends or retracts.

[0039] The adjustment component 3 of this invention can straighten the net body through the pulling member 32 to prevent the net body from being sewn and fixed after being folded. It can also straighten the edge rope to prevent the edge rope from bending and causing the sewing needle to pass through the edge rope, thus greatly improving the product qualification rate.

[0040] Specifically, after the worker passes the net through the hemming assembly 4 as required above, the net is then passed horizontally along the main mounting frame 1 from under the straightening block 316. The edge rope is then adjusted by the positioning wheel 11 until it is parallel to the left and right directions, and the processing operation can begin. First, the pressing cylinder 321 drives the telescopic sleeve 322 to move downward, and the connecting hinge 323 moves downward and changes its angle with the telescopic sleeve 322, pushing the pulling block 324 backward. The above actions are repeated as the pressing cylinder 321 extends and retracts. Then, the second motor 314 drives the crank 312 to rotate, which drives the rocker arm 313 to swing through the connecting rod 315. Under the combined action of the three, the straightening block 316 begins to rotate counterclockwise. Because it is an elastic telescopic structure, it automatically retracts when it contacts the lower side of the main mounting frame 1, and the arc-shaped groove on its lower side straightens the edge rope.

[0041] See Figures 1-3 The clamping assembly 2 includes a primary motor 21 fixedly installed on the rear side of the main mounting frame 1. A main wheel body 22 is fixedly installed on the output shaft of the primary motor 21. Multiple L-shaped grooves 221 are opened on the side of the main wheel body 22. One end of the L-shaped groove 221 is located on the side of the main wheel body 22, and the other end is located on the front side of the main wheel body 22. An ejector block 23 is slidably connected in the opening of the L-shaped groove 221 on the side of the main wheel body 22. The lower side of the ejector block 23 is connected to the main wheel body 22 through a return spring 231. A clamping block 24 is slidably connected in the opening of the L-shaped groove 221 on the front side of the main wheel body 22. The part of the clamping block 24 located in the L-shaped groove 221 is connected to the main wheel body 22 through a return spring 241. A pressure ring 222 is fixedly connected on the circumferential surface of the main wheel body 22 and between the ejector block 23 and the clamping block 24.

[0042] See Figure 3 Both the ejector block 23 and the clamping block 24 have inclined surfaces at their lower ends. The inclined surfaces cooperate with each other. When the ejector block 23 slides inward, the clamping block 24 slides forward under the action of the inclined surfaces. The clamping block 24 is L-shaped, and the end of the clamping block 24 located outside the opening of the L-shaped groove 221 has an elastic telescopic structure. Both the clamping block 24 and the ejector block 23 have chamfers at the ends located outside the main wheel body 22.

[0043] The clamping component 2 of this invention can eliminate the gap between the folded part of the net and the edge rope through the clamping block 24, effectively solving the problem of relative sliding between the edge rope and the net affecting product quality.

[0044] Specifically, as the already rolled and folded net passes under the clamping component 2, motor 21 drives the main wheel 22 to rotate. As the main wheel 22 rotates, the clamping ring 222 clamps the net. Then, the clamping block 24 first contacts the main mounting frame 1. Because it is an elastic telescopic structure, it retracts upon contact with the main mounting frame 1, clamping the already rolled and folded net. Then, the ejector block 23 contacts the main mounting frame 1. As the main wheel 22 rotates, the ejector block 23 retracts into the L-shaped groove 221. Because the ejector block 23 and the clamping block 24 are close together... Both ends are provided with mutually cooperating inclined surfaces. Therefore, when the ejector block 23 retracts into the L-shaped groove 221, the clamping block 24 begins to push forward, clamping the side rope. This effectively solves the problem of relative sliding between the side rope and the net body affecting subsequent sewing processes. As the main wheel body 22 continues to rotate, the ejector block 23 gradually disengages from the main mounting frame 1. The return spring 231 gradually pushes the ejector block 23 back to its original position, and then the reset spring 241 pulls the clamping block 24 back to its original position. The next ejector block 23 and clamping block 24 continue to clamp the already rolled and folded net body according to the above actions.

[0045] After the mesh is tightened, the externally mounted drive wheel continues to pull the mesh to the left, and the sewing machine 5 reliably sews the adjusted and folded mesh. At this point, all the process actions of this invention have been described.

[0046] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, which are still covered within the protection scope of the present invention.
