Description

Technical Field

[0001] The invention belongs to the field of gabion mesh production and processing equipment, and particularly relates to a one-time forming gabion mesh edge locking machine and an edge locking method. Background Art

[0002] Gabion mesh is an indispensable material in dam construction. It can fix the stones used in dam construction, enhance the impact resistance of the dam, and increase the service life of the dam. In modern water conservancy projects and coastal protection projects, gabion mesh plays an extremely critical role in dam construction projects. At present, the annual usage of gabion mesh in my country is about 120 million square meters, and the market demand is huge, which also reflects the wide application and indispensability of gabion mesh in infrastructure construction.

[0003] The production process of gabion mesh includes weaving, cutting and edge locking. Due to its weaving and molding process, the edge shape of the cut gabion mesh after cutting is relatively complex. Manual or semi-automatic equipment is currently used for edge locking, but the existing equipment cannot complete the edge locking task in one go. There will be a section of excess wire at the edge of the mesh, and secondary manual processing is usually required for the excess wire, resulting in large manpower investment and low production efficiency. Summary of the invention

[0004] In view of this, in order to solve the problem that the edge shape of the cutout of the gabion mesh is complex, the existing edge locking equipment cannot complete the edge locking task in one time, and there will be a section of residual thread at the edge of the mesh. The residual thread usually needs to be manually locked twice, resulting in large manpower input and low production efficiency. The present invention proposes a one-time forming gabion mesh edge locking machine and edge locking method, which locks the regular shape area in the middle of the cutting line of the gabion mesh through a plurality of edge locking units arranged in parallel, and adds a residual thread curling mechanism to curl the edge positions on both sides of the gabion mesh with special shapes, so that the edge locking process is automatically formed in one time through the equipment, reducing labor input and improving production efficiency.

[0012] Furthermore, the excess thread curling mechanism is also provided with a shell, the shell is fixedly connected to the edge locking mechanism, and the push cylinder is fixed in the shell.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely explain the technical solutions in the embodiments of the present invention. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict, and the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0042] 1. Specific implementation method 1, see Figure 1-11 The embodiment of the present invention is described. The one-step forming gabion mesh edge locking machine comprises a frame 1, an edge locking mechanism 2 and two residual wire curling mechanisms 3. The edge locking mechanism 2 is fixed on the frame 1. The two residual wire curling mechanisms 3 are respectively fixed on the left and right sides of the edge locking mechanism 2. The edge locking mechanism 2 comprises a plurality of serially connected edge locking units 21.

[0043] The locking unit 21 includes a locking disc 211, a support plate 212 and a driving device. The locking disc 211 is in the shape of a disc with a notch. The locking disc 211 is rotatably fixed on the support plate 212. The driving device drives the locking disc 211 to rotate relatively on the support plate 212.

[0044] The excess thread curling mechanism 3 includes a push cylinder 324 and a rotating cylinder 326. The push cylinder 324 is provided with a telescopic push rod 325. The telescopic push rod 325 and the rotating cylinder 326 are fixedly connected by a linkage plate 322. The front end of the rotating cylinder 326 is provided with a surplus thread clamp 323. The push cylinder 324 and the rotating cylinder 326 are staggered and fixedly connected by the linkage plate 322, and the working strokes of the two are not limited to the same straight line. The total length of the excess thread curling mechanism 3 is reduced, making the device structure more compact.

[0045] See also Fig.11 During operation, the worker first puts the edge wire A into the gaps of multiple locking discs 211, and then combines the edge of the gabion mesh cut with the edge wire A to form multiple closed pentagonal bending areas B, and puts the bending areas B and multiple locking units 21 into the gaps of multiple locking discs 211 in a one-to-one correspondence. Start the equipment, and when the locking disc 211 rotates, it uses the edge wire A as the axis to wind the closed pentagonal bending area B onto the edge wire A, completing the locking of the middle area of ​​the cutting line.

[0046] Since the residual wire C cannot form a closed bending area with the edge wire A, the edge locking is achieved by rotating the notch of the edge locking disk 211. The present application uses the residual wire clamp 323 to curl and wrap the residual wire C in a spiral shape parallel to the edge wire A.

[0047] The invention has a simple structure and is easy to operate. Repeated locking units are used to lock the regular shape area in the middle of the cutting line. Aiming at the problem that the shapes on both sides are complex and cannot be formed by conventional locking mechanisms, a telescopic rotating curling mechanism is designed specifically to change the traditional forming method of bending in the direction perpendicular to the edge wire A, and to curl and wrap the excess wire from both sides, that is, in the direction parallel to the edge wire A. Through the cooperation of the two locking mechanisms, the automatic locking of the equipment is realized in one time, which speeds up the production speed of the gabion mesh and improves the production efficiency.

[0048] The frame 1 of the present application is axially provided with a power shaft 11 and a plurality of support rods 12 .

[0049] The driving device described in the present application includes a transmission gear set and a power gear 213 . The transmission gear set is rotatably fixed on the support plate 212 , and the power shaft 11 drives the power gear 213 to rotate.

[0050] The transmission gear set of the present application includes a meshing transmission gear 1 214 and a meshing transmission gear 215, wherein the transmission gear 1 214 meshes with the power gear 213, and the transmission gear 215 is fixedly connected to the edge locking disc 211. The power shaft drives the gear set to transmit power, and the transmission is precise. The gear set has a compact structure and high space utilization, and is suitable for edge locking units with relatively narrow structures.

[0051] The edge locking unit 21 described in the present application also includes a wire fixing hook 216, which is fixed on the support plate 212 and does not interfere with the edge locking disc 211. A wire fixing component is added to limit and fix the edge wire A to prevent the edge wire A from moving when the equipment is running, thereby improving the stability of the automatic edge locking of the equipment. The wire fixing hook can also be fixed on the frame of the edge locking machine, or a driving component can be added to drive it forward and backward to further fix the edge wire inside the notch of the edge locking disc 211.

[0052] The residual thread curling mechanism 3 described in the present application is also provided with a housing 321, and the housing 321 is fixedly connected to the edge locking mechanism 2, and the push cylinder 324 is fixed in the housing 321. A semi-enclosed space is formed to protect the push cylinder 324 and the rotating cylinder 326 from dust.

[0053] The edge locking machine of the present application can also be equipped with a conveying mechanism to automatically convey the gabion mesh. Alternatively, a hydraulic pressing mechanism can be added to drive the pressing roller up and down using a hydraulic cylinder. When locking the edge, the pressing roller presses down to hold and fix the gabion mesh, further improving the stability of the locking process, reducing manual operation, and improving the degree of automation of the equipment. The edge locking machine of the present application can also be used in combination with existing conveying or pressing equipment.

[0054] The locking method of the above-mentioned one-step forming gabion mesh locking machine adopts the following steps:

[0055] S1, putting the edge wire into the notch of the edge locking disc 211 of the edge locking mechanism 2;

[0056] S2, aligning the gaps of the gabion mesh to be locked with the plurality of locking units 21;

[0057] S3, placing the gabion mesh to be locked into the gaps of the multiple locking discs 211;

[0058] S4, start the equipment, drive the locking disc 211 to rotate to wrap the gabion mesh and the edge wire together, and the excess wire bending mechanism 3 drives the excess wire clamp 323 to rotate to curl the excess wire on the side of the gabion mesh, completing the locking molding of one side of the gabion mesh;

[0059] S5. Turn off the equipment and take out the gabion mesh with the edge locked on one side;

[0060] S6. Turn the gabion mesh 180 degrees with the process cutting line as the axis, and repeat the above steps S1-S5 to complete the edge locking molding on the other side of the gabion mesh.

[0061] The edge locking method has simple steps and is easy to operate. It can realize the one-time forming of the gabion mesh by the single-side edge locking process, which can greatly shorten the time cycle from raw materials to finished products, reduce manual participation, reduce the probability of human errors, and improve the product qualification rate.

[0062] The embodiments of the present invention disclosed above are only used to help illustrate the present invention. The embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described. According to the content of this specification, many modifications and changes can be made. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can understand and use the present invention well.
