Description

Technical Field

[0001] This utility model relates to steel wire mesh processing technology, specifically to a rewinding machine. Background Technology

[0002] In modern construction engineering, the stability and durability of the building's exterior wall system directly affect the structural safety and service life of the entire building. To enhance the crack resistance of exterior wall plaster layers, insulation layers, or waterproof layers, galvanized steel wire mesh is widely used as a reinforcing material. Galvanized steel wire mesh is made of high-strength low-carbon steel wire, welded or woven, and then hot-dip galvanized to improve its corrosion resistance and service life. This material has good mechanical strength, tensile properties, and good adhesion to cement-based materials. In actual construction, to facilitate on-site operation and positioning, construction workers usually need to accurately fix the wire mesh to the wall. To improve construction efficiency and accuracy, existing technologies commonly employ a "embossing and painting" process for pre-treating wire mesh. "Embossing" involves creating regular indentations or raised marks on specific locations on the wire mesh surface using mechanical punching or rolling. These indentations not only provide structural reinforcement but, more importantly, serve as visual guides, assisting construction workers in determining the laying direction, overlap positions, and fixing points of the wire mesh. After embossing, conspicuous paint (such as red or yellow) is usually applied to the indentations to further enhance their visibility and ensure that they are not easily missed or misaligned during construction.

[0003] Currently, most embossing production lines are equipped with simple winding devices. They typically move the wire mesh using traction rollers and rely on passive tension to wind the wire mesh onto the winding rollers. First, the lack of an active pressure mechanism during winding results in loose interlayer bonding, low roll density, and an overall insufficiently compact structure. Second, due to the inherent rigidity of the wire mesh and the gaps in its mesh structure, "serpentine shift" or "interlayer slippage" easily occurs during winding, further exacerbating the looseness problem. Third, the resulting wire rolls are bulky, occupying significant storage space and easily becoming loose and scattered during transportation due to vibration and collisions. In severe cases, this can even lead to the scrapping of the entire roll, affecting construction progress and material utilization. Even if the roll is not completely unrolled, slight loosening can cause mesh distortion and knotting during unwinding, requiring workers to spend extra time and effort to straighten and flatten the mesh, severely slowing down the construction progress. Utility Model Content

[0004] The purpose of this invention is to provide a rewinding machine to solve the problem of loose and easily unwinding steel wire coils in the prior art.

Both the first and second swing plates are movably mounted inside the movable frame via bearings. The first and second swing plates are arranged on both sides of the movable frame. An auxiliary shaft is movably mounted between the first and second swing plates via bearings. Similarly, an auxiliary shaft is movably mounted between the second and third swing plates. Several pressure grooves are formed on the outer side of the auxiliary shaft, which is used to compact the wire mesh. A winding shaft is movably mounted on one side of the movable frame. A wire rope is provided between the winding shaft and the first and second swing plates. A handwheel is connected to one end of the winding shaft.

[0009] Furthermore, support plates are symmetrically installed at the top of the rewinding frame, and a drive shaft is movably installed between the support plates via bearings. The rewinding roller is movably installed on the side of the support plate away from the drive shaft. The drive shaft is axially connected to the rewinding roller. A driven sprocket is fixedly installed at the end of the drive shaft away from the rewinding roller. A servo motor is installed inside the rewinding frame. The servo motor is mounted on the ground via a fixed base. The output end of the servo motor is driven by a drive sprocket via a coupling. The drive sprocket and the driven sprocket are correspondingly arranged, and a chain connects the drive sprocket and the driven sprocket.

[0010] Furthermore, a disc is fixedly installed on the top of the movable frame away from the push frame, and a shaft is fixedly installed at the end of the rewinding roller. The shaft is inserted into the disc. A track is provided at the bottom of the movable frame. The track is fixedly installed on the ground. A track wheel is movably installed at the bottom of the movable frame. The track wheel rolls in cooperation with the track.

[0011] Furthermore, a rack is provided at the bottom of the movable frame, the rack is fixedly installed on the ground, a U-shaped plate is fixedly installed inside the movable frame, and a dual-axis motor is installed on the side of the U-shaped plate near the rack via a fixed seat.

[0012] Furthermore, two fixed blocks are symmetrically installed on one side of the movable frame, the winding shaft is movably installed between the two fixed blocks via bearings, the wire rope is fixedly connected to the outside of the winding shaft, fixed pulleys are movably installed on one side of both the first and second swing plates, the wire rope passes sequentially around the fixed pulleys on the second and first swing plates and is then fixed to one side of the second swing plate, springs connect both the first and second swing plates to the movable frame, and the handwheel is movably installed on the side of the fixed block away from the winding shaft.

[0013] Furthermore, a belt is fixedly connected to the movable frame near the handwheel, the belt covers the outside of the handwheel, and the belt is used to restrict the handwheel from reversing.

A handle is fixedly installed on one side of the arc-shaped positioning plate.

[0016] Compared with existing technologies, the rewinding machine provided by this utility model achieves dynamic layer-by-layer pressing of the wire coil by setting up a double-sided symmetrical auxiliary shaft compaction mechanism. A first swing plate and a second swing plate are symmetrically arranged inside the movable frame. The auxiliary shaft installed on them can actively press against the side of the wire mesh during rewinding under the traction of the wire rope. As the winding process progresses, the coil diameter continuously increases. Under the action of the wire rope, the auxiliary shaft always maintains a close fit with the outer surface of the wire coil, continuously applying uniform lateral pressure. This adaptive compaction mechanism effectively avoids the problem of uneven pressure caused by changes in coil diameter in traditional fixed pressure rollers, ensuring that each layer of wire mesh can be tightly compacted, significantly improving the coil density, reducing interlayer gaps, thereby reducing volume and improving storage and transportation efficiency.

[0017] By laying tracks on the ground, the movable frame can move smoothly forward along the tracks under the drive of a dual-axis motor. The push frame at the top directly pushes the completed wire coil axially out of the rewinding roller. This process requires no manual intervention, is safe and efficient, and significantly improves the continuous operation capability of the production line. Attached Figure Description

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] As attached Figure 1 To be continued Figure 3 As shown:

[0030] Example 1:

[0031] This utility model provides a rewinding machine, comprising:

[0032] The raw material rack 1 and the rewinding rack 12 are provided. The top of the raw material rack 1 is movably provided with a raw material roller 11, which is used to wind the uncompacted wire mesh. The top of the rewinding rack 12 is movably provided with a rewinding roller 13, which is used to wind the wire mesh. A groove 14 is provided on one side of the rewinding roller 13, which is used to fix the wire mesh.

[0033] The feeding mechanism 2 is located on one side of the rewinding frame 12. The feeding mechanism 2 includes a movable frame 21 that is movably installed on one side of the rewinding frame 12. A push frame 22 is fixedly installed on the top of the movable frame 21. The push frame 22 is located on the outside of the rewinding roller 13.

[0034] The compaction mechanism 3 is located inside the movable frame 21. The compaction mechanism 3 includes a first swing plate 31 and a second swing plate 32 symmetrically arranged inside the movable frame 21. The first swing plate 31 and the second swing plate 32 are movably installed inside the movable frame 21 through bearings. The first swing plate 31 and the second swing plate 32 are arranged on both sides inside the movable frame 21. An auxiliary shaft 33 is movably installed between the first swing plate 31 and between the second swing plate 32 through bearings. Several pressure grooves 34 are opened on the outer side of the auxiliary shaft 33. The auxiliary shaft 33 is used to compact the wire mesh. A winding shaft 36 is movably installed on one side of the movable frame 21. A wire rope 37 is arranged between the winding shaft 36 and the first swing plate 31 and the second swing plate 32. A handwheel 310 is connected to one end of the winding shaft 36.

[0035] Specifically, support plates 15 are symmetrically installed at the top of the rewinding frame 12. A drive shaft 16 is movably installed between the support plates 15 via bearings. The rewinding roller 13 is movably installed on the side of the support plate 15 away from the drive shaft 16. The drive shaft 16 is axially connected to the rewinding roller 13. A driven sprocket 17 is fixedly installed at the end of the drive shaft 16 away from the rewinding roller 13. A servo motor 18 is installed inside the rewinding frame 12. The servo motor 18 is installed on the ground via a fixed base. The output end of the servo motor 18 is connected to a drive sprocket 19 via a coupling. The drive sprocket 19 and the driven sprocket 17 are correspondingly arranged. A chain 110 is connected between the drive sprocket 19 and the driven sprocket 17.

[0036] As can be seen from the above, the raw material rack 1 and the raw material roller 11 serve as the unwinding end, used to hold the raw wire mesh roll that has been embossed but is loose. The raw material roller 11 can rotate freely under tension to achieve unwinding. The rewinding roller 13 is the core actuator for winding. The groove 14 on its surface is used to firmly hold the end of the wire mesh at the beginning, providing the initial winding starting point and preventing slippage. Through the insertion shaft 24 at its end, it cooperates with the insertion plate 23 of the movable frame 21 to obtain support on the other side. The servo motor 18 cooperates with the drive sprocket 19, the driven sprocket 17 and the chain 110 to provide power to the drive shaft 16. The servo motor 18 can precisely control the speed and torque, thereby driving the rewinding roller 13 to rotate and achieve winding, ensuring a smooth winding process.

[0037] Working principle: The original steel wire roll is installed on the raw material roller 11 of the raw material rack 1. The starting end of the steel wire mesh is manually pulled out and its end is embedded into the groove 14 on the surface of the rewinding roller 13 to ensure that it is firmly fixed. Then, the servo motor 18 is started to drive the rewinding roller 13 to rotate, realizing the rewinding process of the steel wire mesh from the raw material roller 11 to the rewinding roller 13.

[0038] As attached Figure 1 To be continued Figure 5 As shown:

[0039] Example 2:

[0040] A plate 23 is fixedly installed on the top of the movable frame 21 away from the push frame 22. A shaft 24 is fixedly installed at the end of the rewinding roller 13. The shaft 24 is inserted into the plate 23. A track 25 is provided at the bottom of the movable frame 21. The track 25 is fixedly installed on the ground. A track wheel 26 is movably installed at the bottom of the movable frame 21. The track wheel 26 and the track 25 roll together.

[0041] Specifically, a rack 27 is provided at the bottom of the movable frame 21. The rack 27 is fixedly installed on the ground. A U-shaped plate 28 is fixedly installed inside the movable frame 21. A dual-axis motor 29 is installed on the side of the U-shaped plate 28 near the rack 27 via a fixed seat. The output end of the dual-axis motor 29 is connected to a gear 210 via a coupling. The gear 210 meshes with the rack 27.

[0042] As can be seen from the above, four track wheels 26 are installed at the bottom of the movable frame 21, which cooperate with two tracks 25 on the ground to achieve smooth movement. A rack 27 is laid on the ground. The dual-axis motor 29 inside the movable frame 21 meshes with the rack 27 through the gear 210 to drive the movable frame 21 to move back and forth. A push frame 22 is provided at the top of the movable frame 21. It is a U-shaped metal frame with an inner width slightly smaller than the maximum diameter of the wire coil, which is used to push out the finished coil. A insertion plate 23 is provided at the far end of the movable frame 21, and an insertion shaft 24 is provided at the end of the rewinding roller 13. The two can be inserted and cooperated to achieve dynamic support for the far end of the rewinding roller 13.

[0043] Working principle: After the rewinding roller 13 completes the winding work, the dual-axis motor 29 is started to drive the movable frame 21 away from the rewinding frame 12. The movable frame 21 moves forward, and the push frame 22 applies an axial force to push the wire coil on the outside of the rewinding roller 13 down axially from the outside of the rewinding roller 13, realizing automatic unloading without manual operation.

[0044] As attached Figure 1 To be continued Figure 7 As shown:

[0045] Example 3:

[0046] Two fixed blocks 35 are symmetrically installed on one side of the movable frame 21. The winding spool 36 is movably installed between the two fixed blocks 35 through bearings. The wire rope 37 is fixedly connected to the outside of the winding spool 36. Fixed pulleys 38 are movably installed on one side of the first swing plate 31 and the second swing plate 32. The wire rope 37 passes through the fixed pulleys 38 on the second swing plate 32 and the first swing plate 31 in sequence and is then fixed to one side of the second swing plate 32. Springs 39 are connected between the first swing plate 31 and the second swing plate 32 and the movable frame 21. The handwheel 310 is movably installed on the side of the fixed block 35 away from the winding spool 36.

[0047] Specifically, a belt 311 is fixedly connected to the side of the movable frame 21 near the handwheel 310. The belt 311 covers the outside of the handwheel 310 and is used to limit the reverse rotation of the handwheel 310. A swing frame 312 is hinged to the side of the movable frame 21 near the handwheel 310. The belt 311 is fixedly connected to the swing frame 312 on the side near the swing frame 312. A pedal 313 is fixedly connected to one side of the swing frame 312. A special-shaped rod 314 is fixedly installed on the side of the swing frame 312 away from the pedal 313. Several counterweights 315 are sleeved on the outside of the special-shaped rod 314. A positioning rod 316 is movably installed at the top of the movable frame 21. Two arc-shaped positioning plates 317 are fixedly installed on the outside of the positioning rod 316. The arc surface of the arc-shaped positioning plate 317 fits the outer wall of the rewinding roller 13. The two arc-shaped positioning plates 317 are mounted on both sides of the rewinding roller 13. A handle 318 is fixedly installed on one side of the arc-shaped positioning plate 317.

[0048] As can be seen from the above, the two sets of swing plates are symmetrically arranged. The groove 34 on the outer surface of the auxiliary shaft 33 matches the embossed protrusion of the wire mesh, which can effectively press the material while avoiding damage to the paint surface. Each set of swing plates is connected to the movable frame 21 by a spring 39. Under normal conditions, the swing plates are pulled outward, so that the auxiliary shaft 33 is in a released state away from the rewinding roller 13, which facilitates material feeding and unloading. A winding shaft 36 is installed on the side of the movable frame 21, and a high-strength steel wire rope 37 is wound on the shaft. The other end is fixed to the second swing plate 32, and the cable travels in a "Z" shape around the fixed pulley 38 on the second swing plate 32 and the fixed pulley 38 on the first swing plate 31, forming a "rope tightening" system. When the handwheel 310 is turned, the winding shaft 36 winds up the wire rope 37. The wire rope 37 changes the direction of force through the fixed pulley 38, ultimately pulling the swing plates on both sides together, pressing the auxiliary shaft 33 against the surface of the roll material. The belt 311 is wrapped around the outside of the handwheel 310. The handwheel 310 is used to limit its movement and prevent it from reversing under the action of the spring 39. The belt 311 is made of rubber. The movable frame 21 has a swing frame 312 hinged to its side. One end of the swing frame 312 is connected to the pedal 313, and the other end is connected to the shaped rod 314. Three cast iron counterweights 315 are fitted on the rod. Under the action of gravity, the swing frame 312 tilts to the right, and the belt 311 on it tightly wraps around the outer circumference of the handwheel 310, forming a mechanical self-lock. When the pedal 313 is pressed, the swing frame 312 lifts the counterweights 315, the belt 311 disengages from the handwheel 310, the handwheel 310 is unlocked, and the spring 39 can drive the swing plate to return to its original position. A positioning rod 316 is rotatably installed at the top of the movable frame 21. Two arc-shaped positioning plates 317 are fixed on the rod. Their inner arc surfaces are in contact with the outer wall of the rewinding roller 13 and are arranged symmetrically on the left and right. The arc-shaped positioning plates 317 are used to limit the lateral displacement of the wire mesh during the winding process, prevent the mesh from overflowing, and ensure neat winding.

[0049] Working principle: The wire coil on the raw material roller 11 is pulled out and inserted into the groove 14 of the rewinding roller 13. Then, the arc-shaped positioning plates 317 on both sides are placed on both sides of the rewinding roller 13 to prevent the mesh from shifting during winding, ensuring that the wire mesh can only be wound in the area between the two positioning plates. Stepping on the pedal 313 causes the swing frame 312 to tilt in the opposite direction, the belt 311 to leave the handwheel 310, and the handwheel 310 to lose its limit. Then, the handwheel 310 is rotated, driving the winding shaft 36 to rotate. The wire rope 37 pulls the swing plates on both sides together, so that the auxiliary shaft 33 is close to the rewinding roller 13. Then, the pedal 313 is released. Under the action of the counterweight 315, the swing frame 312 tilts towards the counterweight 315, causing the belt 311 to tightly wrap around the handwheel 310, restricting the handwheel 310. At this time, the spring 39 is under tension. The servo motor 18 is started, and the servo motor 18 drives the transmission shaft 16 to rotate, which in turn drives the rewinding roller 13 to rotate, starting the winding process. During the winding process, the wire roll becomes thicker and thicker. The auxiliary shafts 33 on both sides remain tightly pressed against the sides of the wire mesh to compact it. During this process, the wire roll gradually pushes the auxiliary shafts 33 outwards, and the handwheel 310 will reverse to a certain extent. However, due to the restriction of the belt 311 and the effect of the counterweight 315, the auxiliary shafts 33 can still adhere to the wire roll, ensuring the compaction effect. After winding is completed, the servo motor 18 is stopped, the arc-shaped positioning plate 317 is opened, and the pedal 313 is stepped on to move the belt 311 away from the handwheel 310. The auxiliary shafts 33 leave the wire roll under the action of the spring 39. Then, the pedal 313 is released, and the belt 311 wraps around the handwheel 310 again. The auxiliary shafts 33 are in a state of always being away from the rewinding roller 13. Then, the dual-axis motor 29 is started, and the dual-axis motor 29 drives the gear 210 to rotate, which drives the movable frame 21 to leave the rewinding frame 12. The push frame 22 pushes the wound wire roll off the rewinding roller 13, completing one rewinding operation.

[0050] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
