[0004] The existing devices including the above patent gradually expose the deficiencies of the prior art during use, which are mainly manifested in the following aspects:

[0005] Currently, the replacement welding of the metal mesh of the screen cage mostly relies on the original factory manufacturers and professional welding and installation institutions. It is not only expensive, but also the timeliness of replacement cannot be guaranteed, which cannot meet the continuous production needs of the paper mill and the suddenness during the production process;

[0006] Moreover, due to the large actual size of the cylindrical screen cage, the maintenance personnel in the factory have few opportunities to replace and weld the physical metal mesh. And once mistakes are made, there is a serious waste. Over time, their welding level and quality cannot be effectively exercised, which cannot meet the replacement needs of the metal mesh of the paper machine, and thus affect the product output and quality of the enterprise.

[0007] In summary, it is obvious that the prior art has inconveniences and defects in actual use, so it is necessary to improve it. Content of the Utility Model

[0008] Aiming at the defects in the prior art, the utility model provides a welding practice device for the metal mesh of a cylindrical screen cage to achieve the effect of increasing the cost of replacing the metal mesh of the screen cage and improving the mesh replacement efficiency.

[0009] To achieve the above purpose, the utility model provides the following technical solutions:

[0010] A practice device for welding wire meshes on a circular mesh cage includes two brackets arranged side by side. A fixing ring with a horizontally rotating axis is detachably supported in the area between the two brackets, and a wire mesh support surface is formed by the outer ring of the fixing ring. The inner ring of the fixing ring is fixedly connected to a hub through spokes. A wheel shaft is inserted into the inner hole of the hub, and the wheel shaft is rotatably mounted on the bracket through the wheel shaft.

[0011] As an optimized solution, two support wheels are respectively arranged side by side at the upper ends of each bracket, and the wheel shaft is rotatably supported on the support wheels.

DETAILED DESCRIPTION

[0028] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0029] like Figures 1 to 3As shown in the figure, a circular screen cage wire mesh welding practice device includes two brackets 1 arranged in parallel, and a fixed ring 2 with a horizontally rotatable axis is detachably supported in the area between the two brackets 1. A wire mesh support surface is formed by the outer ring of the fixed ring 2. The inner ring of the fixed ring 2 is fixedly connected to a hub 3 through spokes. A wheel axle 4 is inserted into the inner hole of the hub 3, and the wheel axle 4 is rotatably installed on the bracket 1.

[0030] At the upper part of each bracket 1, two support wheels 5 are arranged in parallel, and the wheel axle 4 is rotatably supported on the support wheels 5.

[0031] Each bracket 1 is also provided with a limiting structure for limiting the wheel axle 4.

[0032] Two positioning screws 13 are connected in parallel on the shaft wall of the wheel axle 4, and the hub 3 is located in the area between the two positioning screws 13.

[0033] A plurality of threaded grooves 14 are arranged in parallel along the axial direction on the shaft wall of the wheel axle 4, and the positioning screws 13 are threadedly connected to the threaded grooves 14.

[0034] The spokes include six straight plate segments 11 evenly distributed along the outer ring of the hub 3. The two ends of the straight plate segments 11 are correspondingly fixedly connected to the outer ring of the hub 3 and the inner ring of the fixed ring 2.

[0035] Auxiliary support segments 12 fixedly connected to the inner ring of the fixed ring 2 are respectively and obliquely fixedly connected to the opposite side walls of one end of the straight plate segment 11 close to the fixed ring 2.

[0036] The limiting structure includes a connecting seat 7 fixedly connected to the upper end of the bracket 1. One end of the connecting seat 7 is connected with a binding strap 6. The other end of the binding strap 6 bypasses above the wheel axle 4 and is connected to the other end of the connecting seat 7.

[0037] Fixed distance plates 8 are respectively fixedly connected to the opposite side walls of the lower ends of the two brackets 1. The two fixed distance plates 8 are overlapped, and a locking structure is arranged between the two fixed distance plates 8.

[0038] The locking structure includes fixed distance holes 9 arranged in parallel on each fixed distance plate 8. A fastening bolt 10 passing through the two coaxially arranged fixed distance holes 9 is arranged between the two fixed distance plates 8.

[0039] The working principle of this device is as follows:

[0040] Among them, the distance between the two brackets 1 can be adjusted to meet the practice use of fixed rings 2 with different widths. Cooperating with the positioning screws 13, they can be connected in the threaded grooves 14 at different positions to realize the positioning of hubs 3 with different widths, increasing the application range of the equipment;

[0041] The edge scraps cut off after the actual round mesh cage is installed are cut into 5cm wide (adjustable) fixed length strips (the length is adjusted according to the actual round mesh cage), and after the ends are butted together, they are put on the designed mesh cage training device. The maintenance personnel can perform continuous mesh cage metal mesh replacement and welding practice by rotating the fixing ring 2. When the quality meets the standard and the level is high, the actual round mesh cage metal mesh of the papermaking machine can be welded and fixed;

[0042] To ensure that the device is as consistent with reality as possible, the diameter of the fixing ring 2 is consistent with the diameter of the actual round mesh cage. At the same time, the actual fixed dimensions of the two ends of the round mesh cage metal mesh are consistent with the width of the wheel ring, so as to ensure that the restoration is as proportional as possible. At the same time, to facilitate continuous operation, the hub 3 of the wheel ring adopts a seamless tube design. At the same time, in order to facilitate flexible rotation, the supports at both ends adopt rotatable support wheels 5. At the same time, taking into account the possibility of falling off under abnormal circumstances, a strap 6 is set at the end of the bracket 1 to limit the wheel axle 4 to prevent the end of the wheel axle 4 from warping, thereby ensuring the stability of the welding learning process; at the same time, the two brackets 1 are separated and connected by fastening bolts 10.

[0043] This round mesh cage metal mesh welding training device reproduces the key points of actual mesh cage metal mesh welding in the factory. Through repeated practice by the operator, the key points and skills of actual mesh cage metal mesh welding and fixing can be mastered. It can not only meet the timeliness requirements of replacing metal mesh in the production process, but also train relevant welding maintenance personnel quickly and at low cost. It can also be used to evaluate the level of metal mesh welding maintenance personnel. This device can not only increase the company's profits, but also improve the level of maintenance personnel, thereby enhancing the overall competitiveness of the company.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
