Description

Technical Field

[0001] This utility model belongs to the technical field of wire mesh production equipment, specifically relating to a buffer device for a wire mesh production line. Background Technology

[0002] After the wire mesh is woven, it requires multiple post-processing steps, such as polishing, grinding, and electroplating. To improve production efficiency, these processes are often linked together in series. However, during the transport of wire mesh between different processes on the production line, intermittent speed differences can occur due to the varying processing techniques. For example, while one wire mesh is being transported from one process to another, the next process may be at a standstill. This can lead to wire mesh accumulation between the two processes, potentially causing bending and affecting product quality. Furthermore, maintaining tension during transport can be difficult, severely impacting subsequent processes. Utility Model Content

[0003] This utility model provides a buffer device for a wire mesh production line, which aims to solve the problem that wire mesh is prone to quality defects during post-processing due to speed differences between processes.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a buffer device for a wire mesh production line, comprising: The fixing frame is defined to be arranged along a first direction in terms of its length direction; Two guide frames are installed at intervals along the first direction on the fixed frame to guide the conveying direction of the wire mesh. A tilting frame is rotatably mounted on the fixed frame and located between the two guide frames. Two tension rollers are rotatably mounted on the tilting frame, and the rotation shaft of the tilting frame on the fixed frame is located between the two tension rollers. A rotary mechanism, connected to the rotating shaft of the flipping frame, is used to pull the flipping frame to rotate so that the wire mesh maintains a certain tension.

[0005] In one possible implementation, two guide rollers are rotatably mounted on the guide frame, and the two guide rollers are spaced apart in the vertical direction to form a guide gap for the wire mesh to pass through.

[0006] In one possible implementation, the tilting frame includes two parallel connecting arms spaced apart, two tension rollers are rotatably disposed at the two ends of the two connecting arms, and the middle part of the connecting arms is rotatably disposed on the fixed frame.

[0007] In one possible implementation, the rotary mechanism includes: A polygonal column is fixedly installed on the rotating shaft of the tilting frame; An adjusting sleeve is detachably mounted on the polygonal column, and the adjusting sleeve is provided with polygonal holes for mounting the polygonal column; A gravity rod is fixedly installed on the outer wall of the adjusting sleeve. The length of the gravity rod is arranged radially along the adjusting sleeve. A gravity block is detachably installed on the gravity rod.

[0008] In one possible implementation, the cross-section of the polygonal column and the cross-section of the polygonal hole on the adjusting sleeve are both regular polygonal structures, and a limiting member for limiting the adjusting sleeve from disengaging from the polygonal column is detachably installed on the outer wall of the polygonal column.

[0009] In one possible implementation, a plurality of gravity rods are fixedly installed on the outer wall of the adjusting sleeve, and the plurality of gravity rods are evenly spaced along the circumference of the adjusting sleeve.

[0010] In one possible implementation, a connecting rod is connected to the gravity block, and a threaded sleeve is fixedly installed at the end of the connecting rod, the threaded sleeve being threadedly connected to the gravity rod.

[0011] In one possible implementation, there are multiple gravity blocks, which are sequentially fitted onto the outside of the connecting rod, and the connecting rod is threaded with a tightening member for limiting the movement of the gravity blocks on the connecting rod.

[0012] The solution shown in this application embodiment, compared with the prior art, features a fixed frame with two guide frames mounted above it. The conveying direction of the wire mesh is aligned with the arrangement direction of the two guide frames, both along a first direction. A tilting frame is rotatably mounted in the middle of the fixed frame, with two tension rollers spaced apart along the first direction on the tilting frame. During the wire mesh conveying process, the wire mesh passes between the two guide frames and wraps around the two tension rollers on the tilting frame. When the tilting frame rotates on the fixed frame, it changes the length of the wire mesh between the two guide frames. The rotation mechanism ensures that the tilting frame always has a tilting force, which keeps the wire mesh taut and rotating on the tilting frame. Therefore, when the length of the wire mesh between the two guide frames changes, the tilting frame drives the two tension rollers to rotate, keeping the wire mesh taut and preventing bending or loosening. This ensures the wire mesh remains taut during post-processing, guaranteeing product quality. Attached Figure Description

Detailed Implementation

[0015] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] Please refer to the following: Figures 1 to 3 The buffer device for a wire mesh production line provided by this utility model will now be described. The buffer device includes a fixed frame 1, a guide frame 2, a tilting frame 3, and a rotating mechanism 4. The fixed frame 1 is defined as having its length direction along a first direction; there are two guide frames 2, which are spaced apart on the fixed frame 1 along the first direction to guide the conveying direction of the wire mesh; the tilting frame 3 is rotatably mounted on the fixed frame 1 and located between the two guide frames 2, and two tension rollers 31 are rotatably mounted on the tilting frame 3. The rotation shaft of the tilting frame 3 on the fixed frame 1 is located between the two tension rollers 31; the rotating mechanism 4 is connected to the rotation shaft of the tilting frame 3 and is used to pull the tilting frame 3 to rotate, thus maintaining a certain tension on the wire mesh.

[0017] The wire mesh production line buffer device provided in this embodiment, compared with the prior art, features a fixed frame 1 with two guide frames 2 mounted above it. The wire mesh conveying direction is aligned with the arrangement direction of the two guide frames 2, both along a first direction. A tilting frame 3 is rotatably mounted in the middle of the fixed frame 1, with two tension rollers 31 spaced apart along the first direction on the tilting frame 3. During wire mesh conveying, the wire mesh passes between the two guide frames 2 and wraps around the two tension rollers 31 on the tilting frame 3. When the tilting frame 3 rotates on the fixed frame 1, it can change the length of the wire mesh remaining between the two guide frames 2. The rotating mechanism 4 ensures that the flipping frame 3 always has a flipping force. Under the action of this flipping force, the wire mesh can always be kept taut and rotated on the flipping frame 3. Thus, when the wire mesh length between the two guide frames 2 changes, the flipping frame 3 drives the two tension rollers 31 to flip, which can keep the wire mesh in a taut state and prevent bending and loosening. This ensures that the wire mesh is always taut during the post-processing process and guarantees product quality.

[0018] Specifically, in this embodiment, guide frames 2 are provided at both the front and rear ends of the fixed frame 1, and guide gaps for the wire mesh to pass through are provided on both guide frames 2. When there is a height difference between the two tension rollers 31 on the flipping frame 3, the guide gap is located between the two tension rollers 31 along the extension direction of the first direction.

[0019] Specifically, in this embodiment, during operation, the wire mesh overlaps the upper side of one tensioning roller 31 and the lower side of the other tensioning roller 31.

[0020] In some embodiments, the guide frame 2 may be adopted as follows: Figure 1 The structure shown. See also Figure 1 Two guide rollers 21 are rotatably mounted on the guide frame 2, and the two guide rollers 21 are spaced apart vertically to form a guide gap for the wire mesh to pass through. One guide roller 21 is directly mounted on the guide frame 2 via a bearing, while the position of the other guide roller 21 on the guide frame 2 can be adjusted vertically, thereby adjusting the size of the guide gap. Guided by the two guide rollers 21, the wire mesh can be smoothly fed into or output from the flipping frame 3.

[0021] In some embodiments, the aforementioned tilting frame 3 may be adopted as follows: Figure 1 The structure shown. See also Figure 1The flipping frame 3 includes two parallel connecting arms 32 spaced apart. Two tension rollers 31 are rotatably mounted at both ends of the two connecting arms 32, and the middle of the connecting arms 32 is rotatably mounted on the fixed frame 1. The two connecting arms 32 are spaced apart and parallel along the axis of rotation of the flipping frame 3 on the fixed frame 1, with the middle of the connecting arms 32 rotatably mounted on the fixed frame 1. Guide rollers 21 are rotatably mounted at both ends of the connecting arms 32, and the two guide rollers 21 are spaced apart and parallel. When the middle of the connecting arm 32 rotates on the fixed frame 1, it can drive the two guide rollers 21 to flip upward and downward respectively, thereby increasing or decreasing the flow rate of the wire mesh between the two guide frames 2.

[0022] Specifically, in this embodiment, when the height difference between the two guide rollers 21 decreases, the amount of wire mesh stored between the two guide frames 2 can be reduced; when the height difference between the two guide rollers 21 increases, the amount of wire mesh stored between the two guide frames 2 can be increased. The rotary mechanism 4 is used to apply a force to the flipping frame 3 to make the two guide rollers 21 rotate in the direction of increasing height difference.

[0023] In some embodiments, the rotary mechanism 4 described above may employ, for example... Figure 2 , Figure 3 The structure shown. See also... Figure 2 , Figure 3 The rotating mechanism 4 includes a polygonal column 41, an adjusting sleeve 42, and a gravity rod 43. The polygonal column 41 is fixedly mounted on the rotating shaft of the tilting frame 3; the adjusting sleeve 42 is detachably mounted on the polygonal column 41, and the adjusting sleeve 42 has polygonal holes for mounting the polygonal column 41; the gravity rod 43 is fixedly mounted on the outer wall of the adjusting sleeve 42, and the length direction of the gravity rod 43 is arranged radially along the adjusting sleeve 42, with a gravity block 44 detachably mounted on the gravity rod 43. The polygonal column 41 is fixedly mounted on the rotating shaft on one side of the tilting frame 3, with its axis coaxial with the rotating shaft. The adjusting sleeve 42 is detachably mounted on the outer side of the polygonal column 41, fitting snugly around the outside of the polygonal column 41. The polygonal holes prevent the adjusting sleeve 42 from rotating relative to the polygonal column 41. Thus, the tilting frame 3 can be rotated under the action of the gravity rod 43.

[0024] Preferably, in this embodiment, during the wire mesh conveying process, the gravity rod 43 is always set at an angle to the vertical direction, so that the gravity block 44 on the gravity rod 43 can always apply a turning force to the turning frame 3, ensuring that the wire mesh always maintains the tension of movement.

[0025] In some embodiments, the polygonal column 41 described above can be adopted as follows: Figure 2 , Figure 3 The structure shown. See also... Figure 2 , Figure 3 The cross-sections of the polygonal post 41 and the polygonal holes on the adjusting sleeve 42 are both regular polygonal structures. A limiting member 411 for preventing the adjusting sleeve 42 from disengaging from the polygonal post 41 is detachably installed on the outer wall of the polygonal post 41. The polygonal post 41 is preferably a regular hexagon or regular octagon. The polygonal holes on the adjusting sleeve 42 are identical polygonal structures, and the polygonal post 41 can slide into the polygonal holes to achieve the installation of the adjusting sleeve 42 and the polygonal post 41. Simultaneously, the angle between the gravity rod 43 and the connecting arm 32 can be changed to adjust the swing amplitude of the connecting arm 32, ensuring that the wire mesh remains taut based on the instantaneous speed difference between two adjacent processes.

[0026] Specifically, in this embodiment, the limiting member 411 is a bolt, which is threaded to one side of the polygonal post 41 and protrudes from the outer wall of the polygonal post 41, thereby preventing the adjusting sleeve 42 from detaching from the polygonal post 41. This ensures the stability of the installation position of the adjusting sleeve 42 and facilitates the disassembly and installation of the adjusting sleeve 42 on the polygonal post 41.

[0027] In some embodiments, the adjusting sleeve 42 may be adopted as follows: Figure 2 , Figure 3 The structure shown. See also... Figure 2 , Figure 3 Multiple gravity rods 43 are fixedly installed on the outer wall of the adjusting sleeve 42, and the multiple gravity rods 43 are evenly spaced along the circumference of the adjusting sleeve 42. Multiple gravity rods 43 are fixedly installed on the outer wall of the adjusting sleeve 42, with adjacent gravity rods 43 arranged at an angle. The arrangement of multiple gravity rods 43 allows for changing the gravity rods 43 connected to the gravity block 44 without removing the adjusting sleeve 42, thereby adjusting the swing amplitude of the flipping frame 3 and ensuring stable tension of the wire mesh. When the process of adjacent post-processing steps of the wire mesh changes, the instantaneous speed difference changes accordingly. By adjusting the connection of different gravity rods 43 to the gravity block 44, the swing amplitude of the flipping frame 3 under the action of the gravity block 44 can be adjusted. Therefore, the connection between the corresponding gravity rod 43 and the gravity block 44 can be adjusted according to the buffer amount of the wire mesh between the two guide frames 2.

[0028] In some embodiments, the gravity block 44 may be as follows: Figure 2 , Figure 3 The structure shown. See also... Figure 2 , Figure 3A connecting rod 45 is connected to the gravity block 44, and a threaded sleeve 46 is fixedly installed at the end of the connecting rod 45. The threaded sleeve 46 is threadedly connected to the gravity rod 43. The gravity block 44 is connected to the connecting rod 45, and a threaded sleeve 46 is fixedly installed at one end of the connecting rod 45. The threaded sleeve 46 and the connecting rod 45 are coaxially arranged. A threaded part is provided at the end of the gravity rod 43 away from the adjusting sleeve 42. By rotating the threaded sleeve 46, the connecting rod 45 can be installed onto the gravity rod 43, thereby realizing the connection between the gravity rod 43 and the gravity block 44.

[0029] Specifically, in this embodiment, during the adjustment process, the corresponding gravity rod 43 can be rotated to the vertical direction by rotating the adjustment sleeve 42 first, and then the gravity block 44 can be installed on the gravity rod 43 through the threaded sleeve 46, thereby facilitating the adjustment of the position of the flipping frame 3.

[0030] In some embodiments, the gravity block 44 may be as follows: Figure 2 The structure shown. See also Figure 2 Multiple gravity blocks 44 are sequentially fitted onto the outside of the connecting rod 45, and the connecting rod 45 is threaded with a tightening member 441 for limiting the movement of the gravity blocks 44 on the connecting rod 45. Two tightening members 441 are threaded onto the connecting rod 45. A support plate is also connected to the bottom end of the connecting rod 45, and the support plate overlaps the tightening members 441 at the bottom end. Multiple gravity blocks 44 are installed above the support plate, and each gravity block 44 has a through hole in its center that slides with the connecting rod 45. Thus, multiple gravity blocks 44 can be fitted onto the connecting rod 45 and overlapped on the support plate, and the tightening members 441 above can fix the multiple gravity blocks 44 on the connecting rod 45.

[0031] Specifically, in this embodiment, the installation of the tightening member 441 allows for the assembly and disassembly of the gravity block 44 on the connecting rod 45, thereby adjusting the tension by adjusting the number of gravity blocks 44. The number of gravity blocks 44 can be increased or decreased according to design parameters, and multiple gravity blocks 44 are fixed between the two tightening members 441 by tightening them.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
