[0033] Combine Figures 1 to 3 As shown, the laser protection device for tobacco sorting equipment in this embodiment includes a bracket 1 and a second protective cover 2. The bracket 1 is fixed relative to the laser. The first protective cover 2 is mounted on the bracket 1. The first protective cover 2 encloses the laser's emitting end along its circumference, extending away from the emitting end in the direction of the laser's emitting end.

[0034] In this embodiment, the first protective cover 2 is arranged at the emitting end of the laser and extends in the direction away from the emitting end. The laser emitted by the emitting end of the laser is covered inside by the first protective cover 2, which is beneficial to prevent the external light source from affecting the laser, thereby ensuring the accuracy of the laser's detection of tobacco to ensure that impurities in the tobacco leaves are sorted out.

[0035] In some embodiments, the first protective cover 2 is sealed with the emitting end at one end thereof close to the emitting end, which helps prevent external light sources from entering the first protective cover 2 through the gap between the emitting end of the laser and the first protective cover 2 and affecting the laser.

[0036] In some embodiments, the laser protection device also includes a sealing strip 6 arranged between the edge of the first protective cover 2 close to the emitting end and the edge of the emitting end, effectively sealing the gap between the emitting end of the laser and the first protective cover 2 to prevent external light sources from entering the first protective cover 2.

[0037] In some embodiments, the cross section of the inner cavity of the first protective cover 2 gradually increases along the direction of emitting laser light as it moves away from the emitting end.

[0038] In this embodiment, the first protective cover 2 includes at least two shells arranged along the circumference of the laser's emitting end. The at least two shells are connected end to end in the circumferential direction of the emitting end. Two adjacent shells are provided separately and connected by a shield fixing member 7. Specifically, in this embodiment, the first protective cover 2 is composed of two shells.

[0039] The laser protection device further comprises a connecting plate 5 for connecting the first protective cover 2 and the bracket 1. Specifically, the connecting plate 5 is welded to the first protective cover 2, and the connecting plate 5 is connected to the vertical rod of the bracket 1 via a threaded connector.

[0040] In some embodiments, the laser protection device further includes a second protective cover 8 , which is connected to an end of the first protective cover 2 away from the emission end and extends away from the first protective cover 2 along the direction of laser emission.

[0041] In some embodiments, the cross section of the inner cavity of the second protective cover 8 gradually increases along the direction of laser emission as it moves away from the first protective cover 2 .

[0042] In some embodiments, the cross-section of the inner cavity of the first protective cover 2 gradually increases along the direction of laser emission as it moves away from the emission end, and the increase in the cross-section of the inner cavity of the first protective cover 2 along the direction of laser emission is smaller than the increase in the cross-section of the inner cavity of the second protective cover 8 along the direction of laser emission.

[0043] In some embodiments, the laser protection device also includes an air duct 3 connected to the first protective cover 2. The air duct 3 is configured to form an air flow in the first protective cover 2 that flows from the end of the first protective cover 2 close to the emission end to the end away from the first protective cover 2. The laser protection device of this embodiment adds an air blowing system to better prevent dust from approaching the laser protective glass through wind pressure, so as to better protect the cleanliness of the protective glass and achieve a better removal effect.

[0044] In some embodiments, the air duct 3 includes an air supply pipe, which is connected to one end of the first protective cover 2 close to the emission end. The air outlet of the air supply pipe blows the air in the first protective cover 2 from one end close to the emission end of the laser to the other end, which is beneficial to prevent dust from approaching the protective glass at the emission end, so as to better protect the cleanliness of the protective glass and achieve a better removal effect.

[0045] Specifically, the laser protection device further includes a connecting tube 4 connecting the air supply pipe and the inner cavity of the first protective cover 2. Optionally, multiple connecting tubes 4 are provided, arranged side by side along the width of the first protective cover 2, perpendicular to the direction of laser emission. Each of the connecting tubes 4 has one end connected to the air supply pipe and the other end connected to the inner cavity of the first protective cover 2.

[0046] The air duct 3 includes a suction pipe that is connected to the end of the first protective cover 2 away from the emission end. The suction pipe provides negative pressure to the end of the first protective cover 2 away from the laser, so that the air in the first protective cover 2 flows toward the end away from the laser. This helps prevent dust from approaching the protective glass at the emission end, thereby better protecting the protective glass from being clean and achieving a better rejection effect.

[0047] This utility model describes a laser protection device for video cabinets that reduces interference from external light sources and keeps laser protective glasses clean, thereby better removing impurities from tobacco, enhancing the taste of cigarettes and improving the customer experience. The addition of an air blowing system prevents dust from approaching the laser protective glass through wind pressure, thereby better protecting the protective glass and achieving a better removal effect.

[0048] Laser protection device. The laser used for tobacco impurity removal has functional characteristics such as color uniformity, specific energy, bioluminescence, and spot scattering. It has stable output, basically no attenuation during its service life, no maintenance, customizable spot, strong directionality, etc. Therefore, on this basis, a protection device is added to prevent the laser from being interfered with by external light sources, making its impurity removal effect more reliable. The wind pressure system (including air duct 3) is added to prevent dust from interfering with the laser impurity removal effect. The wind pressure forms a certain wind pressure in the closed protective cover through the blowing duct, so that dust cannot get close to the dust-proof glass of the laser box, thereby ensuring that the laser is not interfered with by dust through the glass and improving the impurity removal effect.

[0049] In other embodiments, this embodiment further provides a tobacco sorting device, which includes the above-mentioned laser protection device.

[0050] The above are merely exemplary embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
