Description

Technical Field

[0001] This invention relates to the field of steel wire protective netting processing equipment, specifically to an automatic weaving and buckling gun head for steel wire protective netting. Background Technology

[0002] Steel wire mesh protective netting is widely used in many fields such as building protection, slope protection, and garden fencing. Due to its high strength, corrosion resistance, and excellent protective performance, it plays a vital role in ensuring safety and providing isolation and protection. In the production process of steel wire mesh protective netting, fastening is one of the key processing steps. Fastening connects and fixes the steel wires together to form a stable mesh structure.

[0003] Traditional methods of attaching fasteners to steel wire mesh protective netting are mostly manual, requiring workers to use hand-held fastener tools to install and secure each fastener to the intersection of the wires. This manual method has several drawbacks: First, manual operation is extremely inefficient, making it difficult to meet the demands of large-scale production. As market demand for steel wire mesh protective netting continues to increase, the production speed of manual fastening severely restricts the company's capacity. Second, the quality of manual fastening is inconsistent. Due to varying levels of worker skill and work conditions, problems such as insecure fastener installation and inconsistent tightness can easily occur, leading to unstable overall quality of the steel wire mesh protective netting and affecting its performance and safety. Furthermore, long-term manual fastening work is physically demanding, causing worker fatigue, increasing labor costs, and posing significant occupational health risks.

[0004] To improve production efficiency and product quality, some enterprises have begun to adopt semi-automatic buckle-fastening equipment. However, existing semi-automatic buckle-fastening equipment still requires manual assistance in feeding and positioning, resulting in a low degree of automation and inability to achieve fully automated production. Furthermore, the structural design of these devices is not optimal, leading to poor coordination between feeding and clamping actions during the buckling process. This can cause problems such as workpiece jamming and buckle position deviation, resulting in frequent equipment failures, high maintenance costs, and difficulty in meeting the requirements of modern, efficient, and stable production. Therefore, there is an urgent need for an automatic buckle-fastening gun head for steel wire mesh that can achieve automated feeding, precise positioning, and reliable clamping, while also possessing high efficiency and stability. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned problems and provide an automatic weaving and fastening gun head for steel wire protective netting. To achieve the above objective, this invention adopts the following technical solution:

[0006] An automatic weaving and fastening gun head for a steel wire protective net includes a support frame, an upper workpiece, and a lower workpiece. The support frame is equipped with an upper feeding mechanism, an upper pressing mechanism, a lower pushing mechanism, and a lower pressing mechanism. The upper feeding mechanism is located on the side of the upper pressing mechanism, the lower pushing mechanism is located on the side of the lower pressing mechanism, and the upper pressing mechanism is located above the lower pressing mechanism. The upper feeding mechanism pushes the upper workpiece to the upper pressing mechanism, and the lower pushing mechanism pushes the lower workpiece to the lower pressing mechanism. The upper pressing mechanism and the lower pressing mechanism cooperate to splice and press the upper workpiece and the lower workpiece onto the steel wire protective net.

[0007] As an improvement, the upper feeding mechanism includes a hydraulic cylinder, which is fixed on a support frame. The hydraulic cylinder is provided with a telescopic shaft, and the bottom of the telescopic shaft is provided with an upper positioning block. The upper positioning block is provided with an upper positioning groove in the middle, and one side of the upper positioning block is provided with a first notch. The upper feeding mechanism pushes the upper workpiece through the first notch and pushes it into the upper positioning groove.

[0008] As an improvement, the feeding mechanism includes a feeding bin, a first cylinder, a second cylinder, and a first fixed cylinder seat. The feeding bin is fixed to the side of the cylinder, and several workpieces are arranged in the feeding bin. The first fixed cylinder seat is fixed to a support frame, and the first cylinder and the second cylinder are fixed to the first fixed cylinder seat. The first cylinder is arranged above the second cylinder.

[0009] As an improvement, the first cylinder is provided with a first push rod, the second cylinder is provided with a second push rod, the first push rod is shorter than the second push rod, the bottom of the feeding bin is provided with a first through-hole, the front end of the second push rod is inserted into the first through-hole, and the front end of the second push rod stabilizes the workpiece above the first through-hole.

[0010] As an improvement, the lower clamping mechanism includes a third cylinder and a lower positioning block. The lower positioning block is set on the bottom top surface of the support frame, and the third cylinder is fixed on the bottom bottom surface of the support frame. The lower positioning block has a lower positioning groove in the middle, and three positioning plates are arranged around the lower positioning block. The positioning plates position the steel wire protective net. The bottom of the third cylinder has a third push rod, and the bottom of the positioning plate is fixed on the third push rod. The lower positioning block has a second notch on one side, and the lower pushing mechanism pushes the lower workpiece into the lower positioning groove through the second notch.

[0011] As an improvement, the lowering mechanism includes a feeding bin, a fourth cylinder, and a second fixed cylinder seat. The feeding bin and the second fixed cylinder seat are fixed on a support frame. Several lower workpieces are arranged in the feeding bin. The fourth cylinder is fixed on the second fixed cylinder seat. A fourth push rod is provided on the fourth cylinder. A second through-hole is provided at the bottom of the feeding bin. The fourth push rod pushes the lower workpieces into the lower pressing mechanism through the second through-hole.

[0012] As an improvement, the upper positioning block and the lower positioning block are interlocked.

[0013] The advantages of this invention are:

[0014] 1. This invention achieves automatic feeding, precise positioning, and rapid clamping and buckling of the upper and lower workpieces through the coordinated operation of the upper feeding mechanism, the lower pushing mechanism, the upper clamping mechanism, and the lower clamping mechanism. It eliminates the need for manual intervention in feeding, positioning, and other operations, thereby improving the production efficiency of buckling steel wire mesh and meeting the needs of large-scale production. Compared with traditional manual buckling and semi-automatic buckling equipment, the production efficiency is significantly improved.

[0015] 2. The buckle gun head of this invention has a reasonable structural design for each component. The precise positioning of the upper and lower positioning blocks, as well as the stable clamping of the upper and lower clamping mechanisms, ensure that the fasteners at each buckle position are firmly installed and have consistent tightness. This effectively avoids quality problems caused by differences in manual operation, making the overall quality of the steel wire protective net more stable and reliable, and improving the product's qualification rate and market competitiveness.

[0016] 3. The upper feeding mechanism, lower pushing mechanism, upper clamping mechanism and lower clamping mechanism of this invention have precise action coordination. They can work together efficiently in feeding, positioning and clamping, avoiding problems such as workpiece jamming and buckle position deviation, ensuring the smoothness and stability of equipment operation, reducing equipment downtime and further improving production efficiency.

[0037] The present invention will now be described in detail and specifically through specific embodiments to enable a better understanding of the invention. However, the following embodiments do not limit the scope of protection of the present invention.

[0038] Example 1

[0039] This embodiment discloses an automatic weaving and fastening gun head for steel wire protective netting.

[0040] like Figures 1 to 9 As shown, this embodiment includes a support frame 1, an upper workpiece 6, and a lower workpiece 7. The support frame 1 is equipped with an upper feeding mechanism 3, an upper pressing mechanism 2, a lower pushing mechanism 4, and a lower pressing mechanism 5. The upper feeding mechanism 3 is located on the side of the upper pressing mechanism 2, and the lower pushing mechanism 4 is located on the side of the lower pressing mechanism 5. The upper pressing mechanism 2 is located above the lower pressing mechanism 5. The upper feeding mechanism 3 pushes the upper workpiece 6 to the upper pressing mechanism 2, and the lower pushing mechanism 4 pushes the lower workpiece 7 to the lower pressing mechanism 5. The upper pressing mechanism 2 and the lower pressing mechanism 5 cooperate to splice and press the upper workpiece 6 and the lower workpiece 7 onto the wire mesh.

[0041] Upper feeding mechanism 3: The upper feeding mechanism 3 includes a hydraulic cylinder 21, a feeding bin 31, a first cylinder 32, a second cylinder 33, and a first fixed cylinder seat 34. The hydraulic cylinder 21 is fixed on the support frame 1 and serves as the power core of the upper feeding mechanism 3. Its working stability directly affects the conveying accuracy of the upper workpiece 6. The hydraulic cylinder 21 is equipped with a telescopic shaft 22, and the bottom of the telescopic shaft 22 is equipped with an upper positioning block 23. The upper positioning block 23 is equipped with an upper positioning groove 24 in the middle, which is used to accurately position the upper workpiece 6 and ensure the accurate position of the upper workpiece 6 during conveying and subsequent fastening processes. One side of the upper positioning block 23 is equipped with a first notch 25. The upper feeding mechanism 3 pushes the upper workpiece 6 through the first notch 25 into the upper positioning groove 24. The feeding bin 31 is fixed to the side of the hydraulic cylinder 21 and can store several upper workpieces 6 inside, providing material support for continuous production. The first fixed cylinder seat 34 is fixed on the support frame 1. The first cylinder 32 and the second cylinder 33 are fixed on the first fixed cylinder seat 34, and the first cylinder 32 is positioned above the second cylinder 33. The first cylinder 32 is provided with a first push rod 35, and the second cylinder 33 is provided with a second push rod 36. The first push rod 35 is shorter than the second push rod 36. The bottom of the feeding bin 31 is provided with a first through-hole 37. The front end of the second push rod 36 is inserted into the first through-hole 37. During operation, the front end of the second push rod 36 stabilizes the upper workpiece 6 above the first through-hole 37 to prevent the upper workpiece 6 from shifting or falling during the conveying process. The first cylinder 32 pushes the lowermost upper workpiece 6 out of the feeding bin 31 through the first push rod 35, and, in conjunction with the hydraulic cylinder 21 and the telescopic shaft 22, accurately pushes the upper workpiece 6 into the upper positioning groove 24.

[0042] The lowering and pushing mechanism 4 includes a feeding bin 41, a fourth cylinder 42, and a second fixed cylinder seat 43. The feeding bin 41 and the second fixed cylinder seat 43 are fixed on the support frame 1. The feeding bin 41 is used to store several lower workpieces 7, and its structural design ensures that the lower workpieces 7 can smoothly and orderly enter the pushing process. The fourth cylinder 42 is fixed on the second fixed cylinder seat 43, and a fourth push rod 44 is provided on the fourth cylinder 42. A second through-hole 45 is provided at the bottom of the feeding bin 41. The fourth push rod 44 pushes the lower workpieces 7 into the lower pressing mechanism 5 through the second through-hole 45. During operation, the fourth cylinder 42 drives the fourth push rod 44 to push the lower workpieces 7 in the feeding bin 41 out sequentially and accurately push them to the designated position of the lower pressing mechanism 5, realizing the automatic and continuous feeding of the lower workpieces 7.

[0043] Upper clamping mechanism 2 and lower clamping mechanism 5: Upper clamping mechanism 2 is located above lower clamping mechanism 5, and the two work together to complete the buckling operation. Lower clamping mechanism 5 includes a third cylinder 51 and a lower positioning block 52. The lower positioning block 52 is set on the bottom top surface of the support frame 1, and the third cylinder 51 is fixed on the bottom bottom surface of the support frame 1. The lower positioning block 52 has a lower positioning groove 53 in the middle for accurately placing the lower workpiece 7. Three positioning plates 54 are provided around the lower positioning block 52. The function of the positioning plates 54 is to position the wire mesh, ensuring that the position of the wire mesh is accurate during buckling, providing a foundation for high-quality buckling. The bottom of the third cylinder 51 is provided with a third push rod 55. The bottom of the positioning plate 54 is fixed on the third push rod 55. When the third cylinder 51 works, the third push rod 55 drives the positioning plate 54 to move up and down, realizing the clamping and loosening of the wire mesh. A second notch 56 is provided on one side of the lower positioning block 52. The lower pushing mechanism 4 pushes the lower workpiece 7 into the lower positioning groove 53 through the second notch 56. The upper positioning block 23 and the lower positioning block 52 are inserted and engaged. When the upper feeding mechanism 3 pushes the upper workpiece 6 into the upper positioning groove 24 and the lower pushing mechanism 4 pushes the lower workpiece 7 into the lower positioning groove 53, the upper pressing mechanism 2 moves downward, and the upper positioning block 23 and the lower positioning block 52 are inserted. At the same time, the upper pressing mechanism 2 and the lower pressing mechanism 5 apply pressure together to splice and press the upper workpiece 6 and the lower workpiece 7 onto the steel wire protective net, completing the buckling operation.

[0044] Operation process:

[0045] The automatic weaving and fastening device moves the fastening gun head to the wire mesh where fastening is required. At this time, the positioning plate 54 of the lower pressing mechanism 5 rises under the drive of the third cylinder 51. The positioning plate 54 accurately positions the wire mesh where fastening is required, ensuring that the wire mesh remains stable during the subsequent fastening process.

[0046] The upper feeding mechanism 3 and the lower pushing mechanism 4 work simultaneously. In the upper feeding mechanism 3, the second push rod 36 of the second cylinder 33 stabilizes the upper workpiece 6 above the first through-hole 37 in the upper feeding bin 31. The first push rod 35 of the first cylinder 32 pushes the lowermost upper workpiece 6 out of the upper feeding bin 31. Then, the hydraulic cylinder 21 drives the telescopic shaft 22 to move downward, driving the upper positioning block 23 to push the upper workpiece 6 through the first notch 25 to the upper positioning groove 24. At the same time, in the lower pushing mechanism 4, the fourth cylinder 42 drives the fourth push rod 44 to push the lower workpiece 7 in the lower feeding bin 41 into the lower positioning groove 53 of the lower pressing mechanism 5 through the second through-hole 45, thus completing the feeding of the upper workpiece 6 and the lower workpiece 7.

[0047] Under the action of the driving device, the upper pressing mechanism 2 presses down, the upper positioning block 23 and the lower positioning block 52 are inserted and cooperate, and the upper pressing mechanism 2 and the lower pressing mechanism 5 together apply pressure to the upper and lower workpieces 7, tightly splicing the upper workpiece 6 and the lower workpiece 7 and pressing them on the wire mesh, thus completing the buckling operation of the wire mesh.

[0048] After the buckle is applied, the upper clamping mechanism 2 and the lower clamping mechanism 5 return to their initial positions, the positioning plate 54 loosens the wire mesh, and the automatic weaving buckle device moves the buckle gun head to the next buckle position. The above operation process is repeated to achieve continuous automatic buckling of the wire mesh.

[0049] Throughout the entire process, regularly check whether the connecting parts of each mechanism are loose, whether the working status of the cylinder and oil cylinder 21 is normal, and clean the debris in the loading bin 31 and unloading bin 41 in a timely manner to ensure the normal operation of the tapping gun head and production efficiency.

[0050] The specific embodiments of the present invention have been described in detail above, but they are merely examples, and the present invention is not equivalent to the specific embodiments described above. For those skilled in the art, any equivalent modifications and substitutions to the present invention are also within the scope of the present invention. Therefore, all equivalent transformations and modifications made without departing from the spirit and scope of the present invention should be covered within the scope of the present invention.
