Automatic template machining machine

Abstract

The invention relates to template manufacturing equipment, in particular to an automatic template machining machine which comprises a machine frame, a net stretching mechanism and a cutting mechanism.The net stretching mechanism is arranged on the machine frame in a sliding mode, the cutting mechanism comprises a cutting knife driving portion, a guide rail and a grabbing portion, the cutting knife driving portion comprises a motor, a thread rod and a wheel disc, the thread rod is connected with the motor, the motor is fixedly connected with the machine frame, the periphery of the thread rod is further sleeved with a sleeve, the sleeve is fixedly connected with the machine frame, the wheel disc is arranged between the thread rod and the sleeve, the wheel disc and the thread rod are in threaded connection, the wheel disc and the sleeve are in axial sliding connection, the wheel disc is further fixedly provided with a connection rod, a cutting knife is in sliding connection with the connection rod, a second sliding groove is vertically formed in the sleeve, the guide rail forms a rectangular track for cutting knife walking, the grabbing portion comprises a connecting piece, and a wedge block is fixedly arranged on the connecting piece. By the adoption of the scheme, a silk screen can be automatically cut after net stretching is finished.

Description

technical field [0001] The invention relates to a device for making templates, in particular to an automatic template processing machine. Background technique [0002] Precision plate-making refers to materials used for precision plate-making such as steel mesh stretched on the screen frame. In the prior art, during precision plate making, mostly the silk screen is tightened on the screen frame with stencil, and then the screen frame is coated with glue to fix the screen on the screen frame. After the fixation is completed, cut the wire mesh directly above the steel mesh with a blade manually, and then tear off the wire mesh above the steel mesh along the edge of the steel mesh. The prior art has the following problems: 1) Precision plate-making requires that both the wire mesh and the steel mesh on the screen frame have uniform and stable tension. When a worker holds a blade to cut the wire mesh, it is easy to squeeze down the wire mesh located in the middle of the screen ...

AI Technical Summary

Problems solved by technology

The prior art has the following problems: 1) Precision plate-making requires that both the wire mesh and the steel mesh on the screen frame have uniform and stable tension. When a worker holds a blade to cut the wire mesh, it is easy to squeeze down the wire mesh in the middle of the screen frame or stencil, resulting in the produced plate not being able to meet the precision requirements and being discarded, so the professional skills and work experience of the workers are highly required; 2) When workers cut the wire mesh, it is easy to use too much force, and the blade under the wire mesh will appear Scratches on the stencil lead to scrapping of the stencil; 3) The stretching machine cannot automatically cut the wire mesh, so when fixing the wire mesh, someone must be there to operate it, and workers also need to be on hand during the adjustment of the tension of the wire mesh. Waiting by the side leads to a large investment of manpower and material resources, and the production cost of precision plate-making increases
