Description

Technical Field

[0001] The utility model belongs to the technical field of screen transmission auxiliary equipment, and in particular relates to a deviation correction mechanism and a buffer device for long-distance dragging of a nickel spraying screen. Background Art

[0002] The nickel spraying mesh is a process where a layer of nickel-aluminum coating is sprayed on the surface of the mesh, and then it is sent to an alkaline washing tank after a long distance transfer to remove the aluminum in the nickel-aluminum coating. The nickel spraying mesh is transferred over a long distance between the cleaning process, plasma spraying process and alkaline washing tank in sequence. A buffer device is set between the cleaning process and the plasma spraying process to cope with the speed difference of the nickel spraying mesh transfer between the two processes.

[0003] In the prior art, when the wire mesh transfer speed in the alkali washing tank or plasma spraying process is lower than the wire mesh transfer speed in the previous process, the excess wire mesh will stay in the buffer device, and this part of the wire mesh is usually suspended and drooping. Please refer to the patent document (application number: CN202320983611.7, patent name: Transfer buffer device for wire mesh production line used as electrode). When the nickel spray mesh is transferred to the alkali washing tank, due to the different tension of the mesh surface, lateral deviation often occurs, that is, the nickel spray mesh will move in its width direction, which will directly cause the deformation of the nickel spray mesh. In severe cases, the mesh surface will be torn, affecting the production quality and poor practicality. Utility Model Content

[0004] The embodiment of the utility model provides a deviation correction mechanism and a buffer device for long-distance dragging of a nickel spray mesh, aiming to solve the problem of poor practicality of the existing buffer device due to the easy deviation of the nickel spray mesh during the buffering process of the nickel spray mesh.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: to provide a deviation correction mechanism, including:

[0006] There are two support seats, which are arranged at intervals along the width direction of the nickel spraying mesh, each of which is fixed with a fixing frame, and each of which has a sliding cavity arranged along the vertical direction;

[0007] There are two slide seats, and the two slide seats are slidably arranged in the two slide cavities respectively;

[0008] A roller is located between the two slide seats, and connecting structures are respectively provided at both ends of the roller. The roller is connected to the two slide seats respectively through the two connecting structures;

[0009] There are two telescopic structures, and the two telescopic structures are respectively connected to the two slide seats, and each telescopic structure is used to drive the corresponding slide seat to move up and down.

[0010] In a possible implementation, each of the telescopic structures is fixed on the corresponding support seat and is located below the corresponding slide seat, and the telescopic end of the telescopic structure passes through a through hole on the fixed frame and is connected to the bottom end of the slide seat.

[0011] In a possible implementation, each of the connection structures includes:

[0012] A spherical bearing, comprising an outer ring and an inner ring universally rotatably connected to the outer ring, wherein the outer ring is interference-fitted with a fixing hole corresponding to the slide seat;

[0013] A connecting shaft, one end of which is interference-fitted with the inner ring, and the other end of which is slidably connected with a through sliding hole provided in the rotating roller;

[0014] A spring is sleeved on the connecting shaft, one end of the spring abuts against the inner ring, and the other end abuts against the end surface of the roller.

[0015] In a possible implementation, the connecting shaft is a spline shaft, and the through sliding hole is a spline hole.

[0016] In a possible implementation, the deviation-correcting mechanism further includes a tension spring, wherein the tension spring is located in the through sliding hole, and two ends of the tension spring are respectively connected to the two connecting shafts.

[0018] frame;

[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] See also Figure 1 , the deviation correction mechanism provided by the utility model is now described. The deviation correction mechanism includes a support seat 10, a slide seat 20, a roller 30 and a telescopic structure 40. There are two support seats 10, and the two support seats 10 are arranged at intervals along the width direction of the nickel spraying net. Each support seat 10 is fixed with a fixed frame 50, and each fixed frame 50 has a sliding cavity arranged along the vertical direction. There are two slide seats 20, and the two slide seats 20 are respectively slidably arranged in the two sliding cavities. The roller 30 is located between the two slide seats 20, and the two ends of the roller 30 are respectively provided with connecting structures 60, and the roller 30 is respectively connected to the two slide seats 20 through the two connecting structures 60. There are two telescopic structures 40, and the two telescopic structures 40 are respectively connected to the two slide seats 20, and each telescopic structure 40 can drive the corresponding slide seat 20 to move up and down.

[0028] The correction mechanism provided in this embodiment has a correction principle in that, during the transmission process of the nickel spraying net, a laser sensor is set before the plasma spraying process or between the alkali washing tanks, mainly to monitor the side position of the nickel spraying net in real time. This technology is a prior art and will not be repeated here. The data of the laser sensor will be transmitted to the controller in real time, and then the controller drives one or two telescopic structures 40 to drive one or two slides 20 to move up and down, and the nickel spraying net is adjusted by the tilt change of the roller 30 to avoid excessive deviation.

[0029] Compared with the prior art, the correction mechanism provided in the present embodiment has a fixed frame 50, a slide 20 and a telescopic structure 40 independently arranged on each support seat 10. The two slides 20 are driven by the telescopic structure 40 to move up and down respectively, so as to adjust the inclination of the roller 30 in the vertical direction, thereby correcting the nickel spray-coated mesh. The structure is simple, and the quality problems of the nickel spray-coated mesh caused by lateral deviation can be effectively avoided, and the practicability is strong.

[0030] In addition, it should be noted that the deviation correction mechanism can prevent the nickel spray-coated mesh from slipping in the width direction of the nickel spray-coated mesh.

[0031] In some embodiments, the telescopic structure 40 may be configured as follows: Figure 1 See the structure shown. Figure 1 Each telescopic structure 40 is fixed on the corresponding support seat 10 and is located below the corresponding slide seat 20 . The telescopic end of the telescopic structure 40 passes through the through hole on the fixed frame 50 and is connected to the bottom end of the slide seat 20 .

[0032] The telescopic structure 40 is located at the bottom of the fixed frame 50, which can ensure the utilization of space, avoid occupying the space above the fixed frame 50, reduce the overall height, and facilitate the operation of the staff above.

[0033] In some embodiments, the telescopic structure 40 may be configured as follows: Figure 1 See the structure shown. Figure 1 The telescopic structure 40 is an electric cylinder, which is easy to control and has high precision, and can ensure the correction effect.

[0034] In some embodiments, the connection structure 60 may be configured as follows: Figure 3 See the structure shown. Figure 3 Each connection structure 60 includes a joint bearing 61, a connection shaft 62 and a spring 63. The joint bearing 61 has an outer ring and an inner ring universally connected to the outer ring, and the outer ring is interference-fitted with a fixing hole on the corresponding slide seat 20. One end of the connection shaft 62 is interference-fitted with the inner ring, and the other end is slidably connected with a through sliding hole provided in the roller 30. The spring 63 is sleeved on the connection shaft 62, and one end of the spring 63 abuts against the inner ring, and the other end abuts against the end surface of the roller 30.

[0035] When there is a height difference between the two slides 20, the roller 30 tilts. At this time, in order to adapt to this change, the connection shaft 62 is set to ensure that the combination of the connection structure 60 and the roller 30 is a retractable structure 40. At the same time, the joint bearing 61 is set to ensure the tilt change of the roller 30, thereby ensuring the correction effect. Because the roller 30 is sleeved on the two connection shafts 62, the spring 63 can ensure that the roller 30 is bounced at both ends of the roller 30 to ensure that the roller 30 is centered, thereby ensuring that the roller 30 is stably in contact with the nickel spraying net, with a simple structure and strong practicality.

[0036] It should be noted that a limiting portion for limiting the sliding movement of the slide seat 20 is provided in the slide cavity. This technology is prior art and will not be described in detail here.

[0037] In addition, the rotating roller 30 and the two connecting shafts 62 are located on the same axis.

[0038] In some embodiments, the connecting shaft 62 may be Figure 3 See the structure shown. Figure 3 The connecting shaft 62 is a spline shaft, and the through sliding hole is a spline hole. The connection between the spline shaft and the spline hole can ensure the synchronous rotation of the roller 30 and the two connecting shafts 62.

[0039] In some embodiments, the above-mentioned correction mechanism can be used as follows Figure 3 See the structure shown. Figure 3 The deviation correction mechanism also includes a tension spring 64, which is located in the through sliding hole, and the two ends of the tension spring 64 are respectively connected to the two connecting shafts 62.

[0040] The spring 63 is set to bounce the joint bearing 61 to both sides through the connecting shaft 62, and then bounce the slide 20. At this time, both slides 20 will be subjected to an outward pressure. The tension spring 64 can pull the two connecting shafts 62 at the same time, and then give the two connecting shafts 62 an inward pulling force, which can balance the outward pressure on the joint bearing 61 and the slide 20, and thus ensure the stability of the force.

[0041] The utility model also provides a buffer device for long-distance dragging of nickel spraying nets, which can be seen in Figure 2 , including a frame 70 and the above-mentioned correcting mechanism, and the two supporting seats 10 in the correcting mechanism are fixedly arranged at one end of the frame 70.

[0042] Compared with the prior art, the cache device for long-distance dragging of the nickel spray mesh provided in this embodiment can realize the correction of the nickel spray mesh on the basis of buffering through the setting of the correction mechanism. It has a simple structure, can effectively avoid the quality problems of the nickel spray mesh caused by lateral deviation, and has strong practicality.

[0043] It should be noted that the first transfer assembly 80 and the second transfer assembly 90 are spaced apart on the frame 70 and a buffer space is formed therebetween. This technology is prior art and will not be described in detail herein.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
