[0017] The present disclosure will be described below with reference to the accompanying drawings, wherein the accompanying drawings illustrate several embodiments of the present disclosure. However, it should be understood that the present disclosure can be presented in a variety of different ways and is not limited to the embodiments described below; in fact, the embodiments described below are intended to make the disclosure of the present disclosure more complete and fully illustrate the scope of protection of the present disclosure to those skilled in the art. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments. In addition, the drawings only schematically illustrate the embodiments and are not necessarily drawn to scale.

[0018] It should be understood that in all the drawings, the same reference numerals represent the same elements. The terms in the specification are only used to describe specific embodiments and are not intended to limit the present disclosure. All terms (including technical terms and scientific terms) used in the specification have the meanings commonly understood by those skilled in the art unless otherwise defined. For the sake of simplicity and / or clarity, well-known functions or structures may not be described in detail.

[0019] Refer to the following Figure 1 The overall structure of the laser box angle adjustment device according to the embodiment of the present disclosure is described.

[0020] The laser box angle adjustment device according to the embodiment of the present disclosure includes two first brackets 1. For ease of description, the following description will be made with reference to the XYZ coordinate system, wherein the X direction is the longitudinal direction of the first bracket 1, the Z direction is the vertical direction, and the Y direction is the horizontal direction perpendicular to both the X direction and the Z direction.

[0021] Each first bracket 1 is fixed with a second bracket 2 at the top. A rotating shaft 3 extending in the Y direction is rotatably supported between the two second brackets 2 by bearings. Two side panels 4 are fixed on the rotating shaft 3, each of which has an inclined surface 41 inclined relative to the vertical direction and can swing back and forth along the arrow R direction around the axis of the rotating shaft 3. Preferably, the side panels 4 can be roughly triangular. A laser box 5 is fixed on the top of the two side panels 4. A handle 14 is provided on the laser box 5 to facilitate opening the door of the laser box 5. A sponge cover 15 is fixed on the surface of the handle 14, so that the operator is more comfortable when holding the handle 14. When the side panel 4 swings in the R direction, the angle of the laser box 5 fixed on the side panel 4 changes relative to the tobacco conveying device (not shown). In the present disclosure, the rotating shaft 3 is rotatable, and the side panel 4 is fixed relative to the rotating shaft 3, but it is also conceivable that the rotating shaft 3 is set to be fixed and the side panel 4 swings relative to the rotating shaft 3.

[0022] like Figure 1 and Figure 2 As shown, two support blocks 6 are also fixed to the top of each first bracket 1. Support plates 7 extending approximately along the Y direction are fixed to the tops of the two support blocks 6 opposite to each other in the Y direction. Reinforcing rods 13 extending along the Y direction are symmetrically fixed to the bottom of the support plate 7 on both sides in the X direction. The reinforcing rods 13 provide reinforcing support to the support plate 7 to prevent it from bending and deforming after a long time. A cross plate 8 extending approximately along the X direction is fixed to the tops of the two support plates 7, and a translation mechanism 9 and two slide rails 10 extending in the X direction are arranged on the top of the cross plate 8. The two slide rails 10 extending in the X direction are spaced from each other in the Y direction and fixed relatively to the top of the cross plate 8. In this embodiment, the cross section of the slide rail 10 in the YZ plane is in the shape of an "I".

[0023] Refer to the following Figure 2 and Figure 3 The translation mechanism 9 is described in detail.

[0024] The translation mechanism 9 includes a cylinder 901 extending in the X direction and capable of moving back and forth in the X direction. A connecting plate 902 is fixed to one end face (ejection end) of the cylinder 901 in the X direction. A push frame 903 is fixed to the top of the connecting plate 902. Slide blocks 11 are provided on both sides of the bottom of the push frame 903 in the Y direction. The slide blocks 11 are provided with a recess in the shape of an "I" character, which can cooperate with the slide rail 10, so that the push frame 903 can slide back and forth in the X direction on the top of the cross plate 8. Preferably, the cylinder 901 communicates with a solenoid valve not shown, so that the movement of the cylinder 901 and the connecting plate 902 can be controlled by the solenoid valve. Preferably, the cylinder 901 can be moved and stopped at any position within the cylinder stroke range.

[0025] The push frame 903 includes a support 906 and a push plate 907 fixed on the support 906 and extending in the Y direction. The push plate 907 is supported by the support 906. The push plate 907 is rotatably provided with shafts 904 at both ends in the Y direction, and a wheel 905 is fixed on the shaft 904. The surface of the wheel 905 is coated with a coating 12, and the surface of the coating 12 is respectively in contact with the inclined surface 41 of the corresponding side plate 4, such as Figure 2 The coating 12 is made of polyamide material, for example.

[0026] The working process of the laser box angle adjustment device of this embodiment is described below.

[0027] When the angle of the laser box 5 is to be adjusted, the cylinder 901 is activated by the electromagnetic valve to move the connecting plate 902 in the X direction. The push frame 903, the push plate 907 and the wheel 905 move integrally with the connecting plate 902, and then the side plate 4 swings in the R direction under the force of the translation mechanism 9, thereby changing the angle of the laser box 5 relative to the tobacco conveying device. It can be understood that the cylinder 901 can move back and forth in the X direction, and the side plate 4 can swing back and forth in the R direction under the force of the translation mechanism 9 and the moment of gravity of the laser box 5 and the side plate 4 around the rotating shaft 3.

[0028] When the above angle reaches the desired value, the movement of the cylinder 901 is stopped by the solenoid valve, thereby stopping the movement of the side plate 4 and the laser box 5.

[0029] By means of the above laser box angle adjustment device, the angle of the laser box 5 relative to the tobacco conveying device can be adjusted steplessly, so that the laser can be incident on the tobacco conveying device more flexibly. In addition, it is also convenient for the laser box 5 to be maintained in the later stage.

[0030] In addition, the above embodiment of the present disclosure is provided with a wheel 905, so that the friction between the inclined surface 41 and the translation mechanism becomes rolling friction. Preferably, a coating 12 is provided on the wheel 905, which further reduces the friction between the wheel 905 and the inclined surface 41. It is conceivable that the above-mentioned laser box angle adjustment process can be achieved without providing the coating 12 on the wheel 905.

[0031] An embodiment of the present disclosure is described above, but it should be understood that the present disclosure is not limited thereto. A person skilled in the art may conceive of various modifications without departing from the scope of the present disclosure.

[0032] For example, in the embodiment described above, two sets of brackets 1 and 2 are provided, however, it is conceivable that the brackets 1 and 2 may be formed integrally, so that only one bracket or supporting structure is provided to support the laser box angle adjustment device of the present disclosure.

[0033] For example, in the above described embodiments, support blocks 6, support plates 7 and cross plates 8 are provided, however it is contemplated that they may be replaced by one or more support members.

[0034] For example, in the embodiment described above, the cross-section of the slide rail 10 is in the shape of an “I”, and the cross-section of the recessed portion of the slider 11 is also in the shape of an “I”. However, it is conceivable that the cross-section of the slide rail 10 and the cross-section of the recessed portion of the slider 11 can be in other shapes as long as they can match each other so that the slider 11 can slide on the slide rail 10.

[0035] For example, in the embodiment described above, the translation mechanism 9 includes the connecting plate 902 and the support 906 , however, they are not necessary, and it is conceivable that the cylinder 901 is fixed to the push plate 907 so that the push plate 907 moves integrally with the cylinder 901 .

[0036] For example, in the above-described embodiment, the side plate 4 has an inclined surface 41 that interacts with the push plate 907 , however, it is conceivable that the inclined surface 41 may be replaced by a vertical surface to receive the force of the translation mechanism 9 .

[0037] It should be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included in the scope of protection of the present disclosure as defined by the claims. The present disclosure is defined by the attached claims, and the equivalents of these claims are also included.
