Description

Technical Field

[0001] The utility model relates to the technical field of lock engraving, in particular to laser engraving equipment for lock engraving. Background Art

[0002] A lock refers to a device that serves a sealing function, which includes locks, keys and their accessories. It is generally interpreted as "a seal that can only be opened with a key." In addition to being opened with a key, a lock can also be opened with light, electricity, magnetism, sound, fingerprint and other commands. Locks are not only protective equipment, but also have "management" and "decoration" functions. There is also a kind of etiquette in international exchanges that uses the gift of symbolic "keys" as a token of friendship.

[0003] For example, the patent document with the announcement number CN 219333550 U discloses a laser engraving device, including a base, a support rod is arranged on one side of the upper end surface of the base, a connecting block is arranged on the outer side of the support rod, a bracket is arranged on one side of the connecting block, a laser engraving head is arranged on the outer side of the bracket, and an exhaust filter device is arranged on the outer side of the bracket, and the exhaust filter device includes: a slider, a connecting rod, a shell, an air duct, a first fixed rod, a motor, a turntable, a fan blade, a limit block, a second fixed rod, an L-shaped transmission rod, a percussion hammer, a filter tube, a filter hole, an activated carbon filter layer and a filter frame. The laser engraving device can absorb harmful gases such as dust and smoke during the engraving process into the filter tube through the motor, turntable, fan blade and air duct, and filter them through the filter frame and the activated carbon layer. By setting the limit block, the transmission rod and the percussion hammer, the percussion hammer can be used to knock the filter frame when the turntable rotates, so as to ensure that dust will not block the filter screen during use.

[0004] However, in actual use, the dust suction structure can only be simply arranged around the engraving position, which makes it impossible for the dust suction structure to perform a more close and all-round dust suction operation during the entire lock engraving process. The flying dust generated by the engraving can easily affect the engraving effect, and even cause serious damage to the laser engraving equipment, which cannot meet daily use needs. Therefore, it is urgent to design a laser engraving device for lock engraving to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a laser engraving device for lock engraving, so as to solve the problem that the existing structure proposed in the above background technology can only simply arrange the dust suction structure around the engraving position during actual use, resulting in the dust suction structure being unable to play a more close-range and all-round dust suction operation during the entire lock engraving process. The flying dust generated by the engraving can easily affect the engraving effect, and even cause the laser engraving equipment to be damaged, and cannot meet the daily use needs.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a laser engraving device for lock engraving, comprising a dust hood, a dust frame is fixedly connected to the upper and lower ends of the dust hood, a dust grille is arranged on the inner wall of the dust frame, a processing frame is arranged at the inner center of the dust hood, and a laser engraving unit is arranged on the surface of the processing frame;

[0007] A dust conveying hood, the bottom end of the dust collection hood is fixedly connected with the dust conveying hood, and the bottom end of the dust conveying hood is fixedly connected with a fan frame.

[0008] Preferably, a dust removal box is fixedly connected to the bottom end of the fan frame, and dust filters are evenly arranged on the sides of the dust removal box.

[0009] Preferably, a dust suction fan is arranged inside the fan frame, and a lifting push rod is arranged at the inner center of the dust conveying hood.

[0010] Preferably, a first exhaust duct is provided at the four corners of the side of the dust hood, and a first connecting grille is provided on the inner wall of the first exhaust duct.

[0011] Preferably, the four sides of the processing frame are fixedly connected with a second exhaust duct, and the side of the second exhaust duct is provided with a second connecting grille.

[0012] Preferably, dust collection holes are provided inside the dust hood.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The laser engraving equipment for lock engraving can greatly improve the overall dust removal effect during the lock engraving process by means of the dust hood, processing frame, laser engraving unit, dust hood, fan frame, dust suction fan, lifting push rod, first exhaust duct, first connecting grille, second exhaust duct, second connecting grille and dust suction hole groove. In actual use, the staff first puts the lock to be laser engraved into the inner center position of the processing frame for fixing, and then starts the lifting push rod in the inner center of the dust hood to drive the processing frame to descend as a whole to the inside of the dust hood. During the descent, the second exhaust ducts at the four side corners of the processing frame are It can be adaptably connected to the first exhaust duct at the four corners of the side of the dust hood, so that the second connecting grille on the side of the second exhaust duct and the first connecting grille on the inner wall of the first exhaust duct can be quickly connected and connected, and then the dust suction fan inside the fan frame can be started to make the dust suction holes inside the processing frame perform comprehensive suction operations. At this time, when the laser engraving unit on the surface of the processing frame is started to perform lock laser engraving, the generated flying dust can be quickly sucked out from the dust suction holes and grooves, and then transported downward along the first exhaust duct on the side of the dust hood, ensuring that the laser engraving will not be affected by the flying dust, which reflects the practicality of the equipment design.

[0015] The laser engraving equipment for lock engraving further improves the overall use effect of the equipment by arranging a dust hood, a dust frame, a dust grille, a processing frame, a dust hood, a fan rack, a dust removal box and a dust filter. In daily use, when the processing frame is lowered as a whole into the dust hood, the dust frames at the upper and lower ends of the dust hood are also connected with the upper and lower ends of the processing frame respectively. The dust grille on the inner wall of the dust frame is also connected with the fan rack at the bottom of the dust hood through the first exhaust duct, and the suction operation is performed simultaneously, so that part of the overflowing flying dust that cannot be sucked out can be properly sucked in. At the same time, all the flying dust finally enters the dust removal box through the fan rack and is blocked by the dust filter, so that the flying dust is properly handled, which reflects the comprehensiveness of the equipment design.
