Description

Technical Field

[0001] This invention belongs to the technical field of gabion production equipment, and in particular relates to a wire mesh lifting and buffering device. Background Technology

[0002] Gabion mesh cages are an essential material in dam construction. They secure the stones used in dam building, enhancing the dam's impact resistance and extending its service life. Gabion mesh cages play a crucial role in modern water conservancy projects and coastal protection projects. Currently, my country's annual consumption of gabion mesh is approximately 120 million square meters, indicating a huge market demand and reflecting the widespread application and indispensability of gabion mesh cages in infrastructure construction.

[0003] In traditional production processes, the wire mesh weaving machine and the edge trimming machine are adjacent pieces of equipment performing different processes. The wire mesh weaving machine weaves the raw wire into a mesh, while the edge trimming machine, equipped with a drive mechanism such as a toothed drive roller, pulls the wire mesh into the edge trimming machine to complete the edge trimming, and then transports it to the next piece of equipment. Currently, this process has the following problems: 1. When the edge trimming machine produces poor edge wire quality, the mesh weaving machine must be manually paused. The mesh weaving machine will be restarted after the edge trimming machine runs again and the edge wire quality is acceptable. This will cause production interruption and low production efficiency. 2. Frequent starting and stopping of the web editing machine results in energy waste and equipment wear and tear; 3. Frequent manual intervention increases labor intensity and is prone to errors.

[0004] There is an urgent need for a buffer storage device in the current technology, so that when the edge cutting machine needs to process the edge wires a second time, the wire braiding machine does not need to stop, thereby realizing the continuous production of the wire braiding machine. Summary of the Invention

[0005] In view of this, to solve the problem of needing to manually pause the weaving machine when the edge trimming machine produces poor edge trimming results, leading to production interruptions, low production efficiency, energy waste, and equipment wear, this invention proposes a wire mesh lifting and buffering device. Installed between the edge trimming machine and the weaving machine, the device is equipped with lifting rollers on which the wire mesh is placed. When the edge trimming machine produces poor edge trimming results, the weaving machine continues to operate, and the length of the wire mesh to be trimmed between the edge trimming and weaving machines continuously increases. The front end of the wire mesh to be trimmed is fixed by the edge trimming machine's drive mechanism, while the tail end remains connected to the weaving machine. At this time, the lifting rollers are controlled to rise, temporarily storing the wire mesh on both sides of the lifting rollers, providing the edge trimming machine with secondary processing time. Subsequently, the lifting rollers slowly descend, and the edge trimming machine increases its operating speed to catch up and process the temporarily stored wire mesh, restoring normal production rhythm.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a wire mesh lifting and buffering device, comprising a base, a pair of parallel columns, a pair of lifting mechanisms, lifting rollers and a driving mechanism, wherein the bottom of the columns is vertically connected to the base, the lifting mechanisms are connected to the columns one by one, the two ends of the lifting rollers are connected to the lifting mechanisms, and the driving mechanism is mounted on the base and is capable of driving the lifting mechanisms to move the lifting rollers longitudinally.

[0007] Furthermore, the base includes a rectangular frame and a support beam. The support beam is located on a center line of the rectangular frame and is connected to the rectangular frame at both ends. The bottoms of the pair of columns are located at the two ends of the center line and are perpendicularly connected to the rectangular frame.

[0008] Furthermore, the outer wall of the column is provided with a pair of diagonal braces symmetrical about the supporting beam, and the bottom end of the diagonal braces is connected to the rectangular frame.

[0009] Furthermore, a maintenance ladder is installed on the side of the column away from the lifting roller, and the pair of columns are connected by multiple crossbeams.

[0010] Furthermore, the column is a hollow structure, the lifting mechanism is installed inside the column, and the opposing surfaces between the pair of columns are provided with strip-shaped through holes. The two ends of the lifting roller pass through the strip-shaped through holes and are connected to the lifting mechanism.

[0011] Furthermore, the lifting mechanism includes a chain that meshes with each other and a pair of sprockets, the pair of sprockets being installed at both ends inside the column, and the lifting rollers being connected to the chain at both ends.

[0012] Furthermore, the top of the column is provided with a chain tensioning mechanism, which includes a pair of bearing seats, a pair of connecting rods and a pair of nuts. The sprocket located at the top of the column is installed in the pair of bearing seats. The bottom end of the connecting rod is connected to the bearing seat, and the top end penetrates through the top surface of the column. The nut is located on the top surface of the column and is threadedly connected to the connecting rod.

[0013] Furthermore, the sprocket is a double-row sprocket, and the chain consists of two strands.

[0014] Furthermore, the drive mechanism includes a motor, a reducer, and a main drive shaft. The motor and the reducer are both mounted on a base. The input end of the reducer is connected to the motor, and the output end is connected to the main drive shaft. Both ends of the main drive shaft are connected to a pair of lifting mechanisms.

[0015] Furthermore, the reducer is a worm gear reducer.

[0016] Compared with the prior art, the beneficial effects of the wire mesh lifting and buffering device of the present invention are: This invention proposes a wire mesh lifting and buffering device installed between a wire mesh weaving machine and an edge trimming machine. The device includes a lifting roller on which the continuous wire mesh being produced is placed. When the edge trimming machine experiences an edge quality abnormality, the wire mesh weaving machine can continue operating. At this time, the length of the wire mesh to be trimmed increases. By controlling the lifting roller to rise, the wire mesh to be trimmed can be temporarily stored on both sides of the lifting roller, allowing the edge trimming machine time for secondary processing without interrupting the wire mesh weaving machine's production. Afterward, the lifting roller slowly descends, and the edge trimming machine can appropriately increase its speed to process the temporarily stored wire mesh, gradually restoring the production rhythm. This invention, through the structural innovation of the lifting roller, achieves flexible buffering between the edge trimming and weaving processes, avoiding a direct shutdown of the entire production line due to edge trimming abnormalities. This reduces production interruption time, improves the overall utilization rate of equipment, and reduces energy waste and equipment wear caused by frequent start-ups and shutdowns.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other, and the described embodiments are only some embodiments of the present invention, not all embodiments.

[0019] I. Detailed Implementation Method 1, see [link / reference] Figure 1-8 This embodiment describes a wire mesh lifting and buffering device, which includes a base 1, a pair of parallel columns 2, a pair of lifting mechanisms 3, lifting rollers 4, and a drive mechanism 5. The bottom of the columns 2 is vertically connected to the base 1, the lifting mechanisms 3 are connected to the columns 2 one by one, the two ends of the lifting rollers 4 are connected to the lifting mechanisms 3, and the drive mechanism 5 is mounted on the base 1 and can drive the lifting mechanisms 3 to move the lifting rollers 4 longitudinally.

[0020] The base 1 includes a rectangular frame 11 and a support beam 12. The support beam 12 is located on a center line of the rectangular frame 11 and is connected to the rectangular frame 11 at both ends. The bottoms of the pair of columns 2 are located at the two ends of the center line and are perpendicularly connected to the rectangular frame 11.

[0021] See attached document Figure 4 The outer wall of the column 2 is provided with a pair of diagonal braces 21 symmetrical about the support beam 12, and the bottom end of the diagonal braces 21 is connected to the rectangular frame 11.

[0022] A maintenance ladder 22 is installed on the side of the column 2 away from the lifting roller 4, and the pair of columns 2 are connected by multiple crossbeams 23.

[0023] Preferably, the crossbeams 23 consist of two pairs, totaling four beams. One pair is installed on the outer wall of the top of a pair of columns 2, and the other pair is installed on the outer wall of the columns 2 above a pair of diagonal braces 21. The rigidly connected crossbeams 23 form a double-layer frame, improving the overall structural strength. The spacing between the pairs of crossbeams 23 is greater than the diameter of the lifting roller 4 to avoid interference during the lifting and lowering movement of the lifting roller 4.

[0024] See attached document Figure 5 The column 2 is a hollow structure, and the lifting mechanism 3 is installed inside the column 2. Each of the opposing surfaces between the pair of columns 2 is provided with a strip-shaped through hole 24. The two ends of the lifting roller 4 pass through the strip-shaped through hole 24 and are connected to the lifting mechanism 3. Limit sensors are installed on the column 2 to detect the effective stroke of the lifting roller 4.

[0025] See attached document Figure 6The lifting mechanism 3 includes a chain 31 that meshes with each other and a pair of sprockets 32. The pair of sprockets 32 are installed at both ends inside the column 2 and can rotate relative to the column 2. The lifting roller 4 is connected to the chain 31 at both ends and can rotate on its own.

[0026] See attached document Figure 7 The top of the column 2 is provided with a chain tensioning mechanism, which includes a pair of bearing seats 25, a pair of connecting rods 26 and a pair of nuts 27. The sprocket 32 ​​located at the top of the inside of the column 2 is installed in the pair of bearing seats 25. The bottom end of the connecting rod 26 is connected to the bearing seat 25 and the top end penetrates the top surface of the column 2. The nut 27 is located on the top surface of the column 2 and is threadedly connected to the connecting rod 26. When adjusting, turning the nut 27 will drive the connecting rod 26 to rise or fall, thereby driving the bearing seats 25 to rise or fall, so as to adjust the tension of the chain 31.

[0027] See attached document Figure 4 The column 2 has an observation window on the side away from the lifting roller 4, which is used to observe the condition of the chain 31 and add lubricating oil to the chain 31.

[0028] The sprocket 32 ​​is a double-row sprocket, and the chain 31 consists of two chains.

[0029] See attached document Figure 8 The drive mechanism 5 includes a motor 51, a reducer 52, and a main drive shaft 53. Both the motor 51 and the reducer 52 are mounted on the base 1. The input end of the reducer 52 is connected to the motor 51, and its output end is connected to the main drive shaft 53. Both ends of the main drive shaft 53 are connected to a pair of lifting mechanisms 3. The main drive shaft 53 is equipped with multiple couplings. The motor 51 drives the reducer 52 with its dual output shafts, transmitting power to the main drive shaft 53 through the couplings. This causes the sprockets 31 located at the bottom of the inner sides of the columns 2 to rotate synchronously, and the lifting rollers 4 to rise and fall via the chains 31.

[0030] The reducer 52 is a worm gear reducer.

[0031] The working principle of this invention is as follows: A wire mesh lifting and buffering device, as described in this invention, is arranged in the wire mesh production line, positioned between the weaving machine and the edge-cutting machine. During normal operation, the wire mesh overlaps on the lifting roller 4, with the mesh sheet approximately 1 meter above the ground. When the edge-cutting machine experiences an edge-cutting quality abnormality, requiring secondary cutting or other reasons preventing operation, the length of the wire mesh to be cut increases. At this time, the starter motor 51 drives the main drive shaft 53 to rotate via the reducer 52, which in turn drives the sprocket 31 located at the bottom of the column 2 to rotate. This causes the lifting roller 4 to rise with the chain 31, temporarily storing the wire mesh to be cut on both sides of the lifting roller 4 (similar to the principle of a clothes rack), thus providing time for the edge-cutting machine to perform secondary processing. During this time, the weaving machine and all preceding processes can continue to operate normally without stopping. The subsequent lifting roller slowly descends, and the edge-cutting machine can appropriately increase its speed to process the temporarily stored wire mesh, gradually restoring the production rhythm.

[0032] This invention, through structural innovation, achieves flexible buffering between the edge cutting and weaving processes, providing secondary processing time for the edge cutting machine and avoiding a complete shutdown due to edge cutting abnormalities. This reduces production interruption time, improves the overall utilization rate of equipment, and reduces energy waste and equipment wear caused by frequent start-ups and shutdowns. It solves the pain points of low production efficiency, frequent manual intervention, and resource waste in traditional technologies, and provides reliable technical support for the automated production of cages.

[0033] The embodiments of the present invention disclosed above are merely illustrative of the invention. These embodiments do not exhaustively describe all details, nor do they limit the invention to the specific implementations described. Many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention.
