[0023] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. The description of the at least one example embodiment is actually only illustrative, but not as any limitation on the present disclosure, the application or use thereof.

[0024] As shown in Figure 1 and Figure 2 The present embodiment provides an optical signal transmission end face transparent dust baffle, comprising: a transparent dust baffle, a press bar machine hopper and a rotating stud;

[0025] The surface of the transparent dust baffle is provided with a hole, and the rotating stud is threadedly connected in the hole; one end of the rotating stud located in the press bar machine hopper is provided with an inclined surface;

[0026] The surface of the transparent dust baffle is provided with a through hole, and the transparent dust baffle is installed on the side of the press bar machine hopper through the through hole.

[0027] The thread in the hole is selected as M16*1 thread; by selecting M16*1 fine thread, compared with coarse thread, the density of the thread is increased, the stability and fastening force of the connection are improved, and at the same time, the rotating stud is prevented from being shaken out and sealed during the vibration of the press bar machine hopper during work.

[0028] The other end of the rotating stud is provided with an outer hexagonal structure; the outer hexagonal structure can facilitate the staff to adjust the depth of the rotating stud with a wrench.

[0029] The inclined surface is provided as an inclination of 15°, and the surface is covered with an electrostatic film; so that when the tobacco dust forming machine group vibrates, the ash in the hopper is prevented from adhering, and at the same time, the inclined surface is combined with the falling of the tobacco dust itself due to gravity to realize the sliding of the tobacco dust.

[0030] The through hole annular array is around the rotating stud, the through hole is used for passing through a screw, and the transparent dust baffle is threadedly connected with the press bar machine hopper body through the screw; the accumulation of ash and tobacco dust in the hopper can be observed through the transparent dust baffle.

[0031] The surface of the rotating stud is provided with an external thread matched with the thread, the length of the external thread is three fifths of the overall length of the rotating stud; meanwhile, a locking nut is provided, the locking nut is screwed on the side away from the beveled end of the rotating stud; at this time, the rotating stud can be regarded as a screw rod, and the double-nut structure is realized in combination with the locking nut, so as to further improve the locking capacity of the equipment and reduce the influence of vibration in the working process of the rod pressing machine; the length limitation of the external thread can ensure that the rotating stud will not be excessively rotated when the length is adjusted.

[0032] A sealing ring is arranged between the locking nut and the transparent ash blocking plate; the M16*1 fine thread in combination with the sealing ring can ensure that the ash and tobacco residue will not overflow from the rotating stud.

[0033] Overall, the present application provides a photoelectric signal transmission end face distance adjustable transparent ash blocking plate. The fixing screw fixes the transparent ash blocking plate on the side of the rod pressing machine hopper through four threaded holes. The transparent ash blocking plate facilitates the observation of the ash and tobacco residue accumulation in the hopper. The geometric center of the four threaded holes is a transparent stud. The signal of the photoelectric sensor is transmitted through the transparent stud, so as to determine the amount of ash and tobacco residue in the hopper and control the operation of the rod pressing machine. The transparent stud moves forward and backward by rotating the control stud body through the fine thread, so as to prevent the accumulation of tobacco residue from blocking the photoelectric signal transmission. The locking nut is used to reduce the movement of the transparent stud caused by the vibration of the tobacco residue forming machine group. The sealing ring plays a sealing role to prevent the ash and tobacco residue in the hopper from leaking out. The end of the transparent stud outside the hopper is hexagonal, which facilitates the position adjustment of the transparent stud. The end inside the hopper is a 15° bevel with an electrostatic film attached to prevent tobacco residue from adhering thereto.
