Description

Technical Field

[0001] The utility model relates to the field of metal door processing, in particular to a pre-marking mechanism for metal door processing. Background Art

[0002] Metal door processing can be divided into many categories according to material, process and purpose. It is widely used in civil and commercial buildings and residences, including European retro style, simple modern style, American style, Mediterranean style, Chinese style, French romantic style and Italian style. With the continuous development of society and people's requirements for living environment, the use of fire doors has gradually entered thousands of households. In the production process of metal doors, the surface needs to be cut into predetermined sizes through cutting components, making the appearance of fire doors look more beautiful.

[0003] According to the published patent 202010991244.6, a pre-marking mechanism for metal door processing includes a support frame, a placement frame is fixedly connected inside the support frame, a lifting mechanism is fixedly connected to the top of the placement frame, the front and rear sides of the support frame are movably connected with dovetail blocks, and the surface of the support frame is provided with a dovetail groove used in conjunction with the dovetail block. The present invention solves the problem of cutting metal doors by manual marking during cutting by setting a support frame, a placement frame, a lifting mechanism, a dovetail groove, a dovetail block, a cylinder, a support rod, a support plate, a slider, a slide, a fixed shell, a traction block, a rope, a pulley, a funnel, a feed port, a discharge port, a drop bead, a support block, a spring, a through hole, a limit groove and a placement groove. This method not only wastes time, but also causes the mark to be skewed due to manual marking, resulting in the problem that the cut fire door does not meet the standard. In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved. Although the support frame, the placement frame, the lifting mechanism, the dovetail groove, the dovetail block, the cylinder, the support The coordinated use of rods, support plates, sliders, slides, fixed shells, traction blocks, ropes, pulleys, funnels, feed ports, discharge ports, beads, support blocks, springs, through holes, limit slots and placement slots solves the problem of manual marking when cutting metal doors. This method not only wastes time, but also causes the marking to be skewed due to manual marking, resulting in the problem that the cut fire doors do not meet the standards. During use, the traditional pre-marking mechanism for metal door processing uses beads for pre-marking. However, in the process of using beads for pre-marking, the rope will shake during movement, causing the funnel and beads to shake, so that the beads cannot stably contact the door body, affecting the marking of the powder. For this reason, a new technical solution needs to be designed to solve the problem. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art, meet the actual needs, and provide a pre-marking mechanism for metal door processing to solve the current traditional pre-marking mechanism for metal door processing, which uses pendants to achieve pre-marking. However, in the process of using pendants for pre-marking, the rope will shake during the movement, causing the funnel and the pendants to shake, so that the pendants cannot stably contact the door body, affecting the technical problem of powder marking.
