Description

Technical Field

[0001] The utility model relates to the technical field of full-cover engraving machines, in particular to an automatic closing device for the door of a full-cover engraving machine. Background Technique

[0002] The full-cover engraving machine is a numerical control engraving machine, and its protective cover is mainly used to prevent the highly rotating cutter, the generated chips and the clamped workpieces inside from flying out of the processing chamber under the action of centrifugal force or impact during the processing process, causing injury to workers.

[0003] However, due to the non-standard operation of workers, many processing accidents are caused by workers not closing the chamber door during the processing process, resulting in the flying out of the cutter or workpiece and causing personal injuries. Therefore, during processing, having an automatic closing function for the chamber door can effectively reduce the occurrence of safety accidents. At the same time, the automatic closing device for the chamber door also needs to have an automatic stop function when the closing of the chamber door is blocked to avoid pinching workers. In order to ensure that the chamber door can be opened and closed smoothly, it is necessary to effectively clean the chamber door track. Content of the Utility Model

[0004] The utility model aims at the defects in the prior art and provides an automatic closing device for the door of a full-cover engraving machine.

[0005] The utility model is realized by the following technical solutions:

[0006] An automatic closing device for the door of a full-cover engraving machine includes an engraving machine housing, a chamber door frame, a fixed chamber door, a movable chamber door assembly, an electric telescopic rod, an air outlet pipe and an air inlet pipe. The chamber door frame is fixedly arranged inside the engraving machine housing. The fixed chamber door is fixedly arranged inside one side of the chamber door frame. The movable chamber door assembly is clamped inside the chamber door frame. The electric telescopic rod is installed at the bottom of one side of the chamber door frame. The air outlet pipe is arranged at the telescopic end of the electric telescopic rod. The air inlet pipe is fixedly arranged outside one end of the air outlet pipe. The movable chamber door assembly includes a sliding door, a contact strip, a contact switch, a contact point, a connecting rod and a spring. The sliding door is clamped inside the chamber door frame. The contact strip is clamped outside one end of the sliding door. The contact switch is fixedly arranged at the top of one side of the sliding door. The contact point is fixedly arranged inside the contact strip. The connecting rod is arranged inside the contact strip. The spring is sleeved outside the connecting rod.

[0007] In a preferred embodiment of the utility model, one end of the connecting rod penetrates and extends to the inside of one side of the sliding door, and a limiting piece is arranged at its end. The spring is arranged between the sliding door and the contact strip;

[0008] When the closing of the sliding door is blocked, the spring is compressed and contracted, so that the contact switch contacts the contact point, and the electric telescopic rod can be stopped from extending through the controller, avoiding the situation of pinching workers.

[0009] In a preferred embodiment of the present utility model, the air outlet pipe is clamped inside the bottom of the sliding door and fixedly connected to the sliding door. One end of the air outlet pipe is clamped at the bottom of the contact strip, and a clamping hole matching the air outlet pipe is formed at the bottom of the contact strip. The end of the air outlet pipe located inside the contact strip and the bottom of one end outside the sliding door are provided with air outlet holes arranged obliquely downward.

[0010] The air inlet pipe inputs compressed air into the air outlet pipe through an air pump. When the sliding door moves forward, the air outlet holes at the end of the air outlet pipe clean the sliding groove of the sliding door. During the opening process of the sliding door, the air outlet holes at its tail end clean the inside of the sliding groove, thus ensuring the smooth opening and closing of the sliding door.

[0011] In a preferred embodiment of the present utility model, a compression groove matching the spring is formed inside the contact strip, and the contact point and the contact switch are concentrically arranged.

[0012] The compression groove inside the contact strip provides space for the compression and installation of the spring, ensuring that the contact switch and the contact point can be effectively contacted when compressed.

[0013] In a preferred embodiment of the present utility model, a sliding groove matching the sliding door is formed inside the storage door frame.

[0014] The beneficial effects of the present utility model are as follows:

[0015] Before processing, the fully enclosed engraving machine storage door automatic closing device automatically closes the storage door through the electric telescopic rod. During the closing and opening processes, the sliding groove where the storage door is installed is effectively cleaned, ensuring smooth sliding of the storage door. Moreover, the storage door is equipped with a protection device, which can automatically stop when encountering an obstacle, avoiding pinching workers. The automatic closing of the storage door effectively prevents the running tool or the clamped workpiece from flying out, thus greatly reducing the probability of safety accidents and improving the safety of equipment use.

[0023] The following describes in detail the preferred embodiments of the present utility model with reference to the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. The directional terms mentioned in the present utility model, such as "up", "down", "front", "rear", "left", "right", "top", "bottom", etc., are only with reference to the directions of the attached drawings. Therefore, the directional terms used are for explaining and understanding the present utility model, rather than for limiting the present utility model.

[0024] As Figures 1-6 shown, a fully enclosed engraving machine door automatic closing device includes an engraving machine housing 1, a door frame 2, a fixed door 3, a movable door assembly 4, an electric telescopic rod 5, an exhaust pipe 6 and an intake pipe 7. The door frame 2 is fixedly arranged inside the engraving machine housing 1. The fixed door 3 is fixedly arranged inside one side of the door frame 2. The movable door assembly 4 is clamped inside the door frame 2. The electric telescopic rod 5 is installed at the bottom of one side of the door frame 2. The exhaust pipe 6 is arranged at the telescopic end of the electric telescopic rod 5. The intake pipe 7 is fixedly arranged outside one end of the exhaust pipe 6. The movable door assembly 4 includes a sliding door 41, a contact strip 42, a contact switch 43, a contact point 44, a connecting rod 45 and a spring 46. The sliding door 41 is clamped inside the door frame 2. The contact strip 42 is clamped outside one end of the sliding door 41. The contact switch 43 is fixedly arranged at the top of one side of the sliding door 41. The contact point 44 is fixedly arranged inside the contact strip 42. The connecting rod 45 is arranged inside the contact strip 42. The spring 46 is sleeved outside the connecting rod 45.

[0025] Specifically, one end of the connecting rod 45 penetrates and extends to the inside of one side of the sliding door 41, and a limiting piece is arranged at its end. The spring 46 is arranged between the sliding door 41 and the contact strip 42. The air outlet pipe 6 is clamped inside the bottom of the sliding door 41 and is fixedly connected to the sliding door 41. One end of the air outlet pipe 6 is clamped at the bottom of the contact strip 42. A clamping hole matching the air outlet pipe 6 is opened at the bottom of the contact strip 42. Air outlet holes are opened at the end of the air outlet pipe 6 located inside the contact strip 42 and at the bottom of one end outside the sliding door 41 and are arranged obliquely downward. A compression groove matching the spring 46 is opened inside the contact strip 42. The contact point 44 and the contact switch 43 are concentrically arranged. A sliding groove matching the sliding door 41 is opened inside the door frame 2 of the storage compartment.

[0026] In this embodiment, when the engraving machine starts to run the processing program, first, the electric telescopic rod 5 will extend out in advance before the processing program runs. The telescopic end of the electric telescopic rod 5 acts on the tail end of the air outlet pipe 6, and the air outlet pipe 6 is fixedly connected to the sliding door 41. Therefore, when the electric telescopic rod 5 extends out, it will push the sliding door 41 forward until the sliding door 41 is closed. When the sliding door 41 is closed and clamped into the sliding groove inside the door frame 2 of the storage compartment, the contact strip 42 will be squeezed by the sliding door 41, causing the spring 46 to be compressed and contracted. At this time, the contact switch 43 contacts the contact point 44, and the electric telescopic rod 5 stops extending and retracts backward, thereby realizing the automatic closing of the storage compartment door.

[0027] Furthermore, when the electric telescopic rod 5 drives the sliding door 41 to move forward, if it encounters an obstacle, resulting in the contact strip 42 being blocked, the spring 46 is compressed and contracted, and the connecting rod 45 moves into the sliding door 41. At this time, the contact switch 43 and the contact point 44 will come into contact in advance, causing the electric telescopic rod 5 to stop extending and retract, thereby avoiding the sliding door 41 from squeezing the worker and improving safety. The air outlet pipe 6 is fixed inside the bottom of the sliding door 41. The front end of the air outlet pipe 6 is clamped at the bottom of the contact strip 42, and its tail end is located outside one side of the sliding door 41. Air outlet holes are opened at both the front end and the tail end of the air outlet pipe 6. When the air pump is connected to the air inlet pipe 7 and high-pressure air is introduced into the air outlet pipe 6, during the forward movement of the sliding door 41, the air outlet holes at the front end of the air outlet pipe 6 clean the inner side of the forward sliding groove. When the sliding door 41 is opened, the air outlet holes at the tail end of the air outlet pipe 6 clean the inner side of the rearward sliding groove, thereby ensuring that chips and other impurities will not affect the sliding of the sliding door 41 and ensuring the smooth operation of the sliding door 41.
