AI Technical Summary
Existing wire mesh trimming devices are inefficient and labor-intensive when processing irregularly shaped wire meshes, especially those with large mesh openings, and cannot efficiently complete the trimming task.
The design includes a frame, forward and backward guide rails, a moving sleeve, a horizontal connecting rod, an edge trimming mechanism, and a servo motor. The servo motor controls the forward and backward movement of the moving edge trimming frame to ensure that the weft yarns accurately enter the edge trimming mechanism for trimming. The spacing of the trimming mechanism can be adjusted to accommodate different mesh widths.
It improves trimming efficiency, reduces labor intensity, expands the applicability of the device, and ensures the quality of weft wire end trimming.

Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of mesh weft trimming device, especially relates to a mesh trimming device for uneven mesh holes. BACKGROUND
[0002] The existing mesh trimming device includes a frame body with fixed bases at both ends, a trimming mechanism is fixed on the frame body, and the trimming mechanism cuts off the corresponding weft end of the mesh when the weft reaches between the upper cutter and the lower cutter of the trimming mechanism. For breeding isolation mesh and other special-shaped meshes, the size of the mesh holes is different, and the distance between adjacent wefts is different. The following two trimming methods are mainly used: one is to trim the mesh by using the existing mesh trimming device. When a large mesh hole is encountered, the mesh pulling mechanism pulls the mesh at a large distance. When the mesh pulling mechanism pulls the mesh at a large distance, the corresponding weft of the trimming device is located between the upper cutter and the lower cutter. At this time, the mesh is in the process of moving, so trimming cannot be completed. In order to trim the mesh by using the existing trimming device, the pulling range is determined according to the shortest distance between two adjacent wefts. After each pulling, the trimming device trims the corresponding weft end. In this way, the mesh welding efficiency is greatly reduced. The second is to manually trim the weft of the mesh, which is labor-intensive and low in production efficiency. SUMMARY
[0003] The technical problem to be solved by the utility model is to provide a mesh trimming device for uneven mesh holes, which is low in labor intensity, high in trimming and welding efficiency, and wide in application range.
[0004] To solve the above problems, the technical scheme of the mesh trimming device for uneven mesh holes is as follows: a frame body with fixed bases at both ends is provided, a forward and backward guide rail consistent with the advancing direction of the mesh is arranged above the fixed base, a front and rear moving sleeve is arranged on the forward and backward guide rail, the front and rear moving sleeve is fixedly connected with a moving trimming frame, a transverse connecting rod is arranged between the moving trimming frames at both sides, a trimming base is arranged on the transverse connecting rod, a trimming mechanism is arranged on the trimming base, a rack is arranged below the moving trimming frame, a servo motor is connected to the frame body through a bearing seat, and a gear meshing with the rack is arranged at the corresponding position of the transmission shaft of the servo motor.
[0005] The additional technical features are as follows:
[0006] A transverse moving sleeve is arranged on the transverse connecting rod, and the transverse moving sleeve is connected with the trimming base.
[0007] The uneven mesh trimming device has the following advantages compared with the prior art: firstly, the frame body with the fixed base at both ends is arranged, the advancing and retreating guide rails consistent with the advancing direction of the mesh are arranged above the fixed base, the front and rear moving sleeves are arranged on the advancing and retreating guide rails, the front and rear moving sleeves are fixedly connected with the moving trimming frames, the lateral connecting rods are arranged between the moving trimming frames on both sides, the trimming bases are arranged on the lateral connecting rods, the trimming mechanisms are arranged on the trimming bases, the racks are arranged below the moving trimming frames, the servo motor is connected with the racks through the bearing seat on the frame body, the transmission shaft of the servo motor is provided with the gear engaged with the rack at the corresponding position of the rack, the fixed base is fixed on the mesh frame body on the two sides of the mesh, when the large mesh is welded by the welding machine, the mesh frame body is pulled forward to increase the pulling distance of the mesh, at this time, the servo motor is started, the moving trimming frame moves forward relative to the fixed base by the same distance as the pulling distance, and then the servo motor is stopped, so that the next weft to be trimmed falls in the trimming mechanism, the trimming mechanism trims the weft, at this time, the mesh frame body continues to pull the mesh by a short distance, and the moving trimming frame does not move relative to the fixed base, when the weft to be trimmed and the weft just trimmed behind the trimming mechanism serve as two edges of the large mesh, the servo motor is reversely rotated to drive the moving trimming frame to move backward relative to the fixed base by the distance of the large mesh, at this time, the weft to be trimmed falls in the trimming mechanism, and the trimming mechanism trims the weft, so that all the weft ends can be trimmed in sequence, the working efficiency is improved, the labor intensity is reduced, and the trimming quality of the weft ends is good; secondly, the lateral moving sleeves are arranged on the lateral connecting rods, the lateral moving sleeves are connected with the trimming bases, the distance between the trimming mechanisms on both sides can be adjusted according to the width of the mesh, and the application range is wider.
