[0005] It also includes a fixed plate and a sliding seat slidably arranged on the fixed plate. The other end of the cantilever is arranged on the sliding seat. The cantilever has the freedom of translation with the help of the sliding seat.

[0006] One end of the cantilever is hinged on the sliding seat.

[0007] It also includes an articulated seat arranged on the sliding seat and a spring pull rod arranged on the side of the articulated seat. One end of the cantilever is hinged on the articulated seat, one end of the spring pull rod is connected to the side of the articulated seat, and the other end is connected to the side of the cantilevered end of the cantilever.

[0008] The upper end surface of the fixed plate is provided with two sliding grooves in parallel, and the lower end surface of the sliding seat is provided with two raised sliding blocks in parallel and respectively embedded in the sliding grooves, and the sliding blocks correspond to and fit the sliding grooves.

[0009] It also includes a shooting stand, which includes a mounting plate fixed on a diffuse reflection arch cover, a U-shaped frame fixed on the mounting plate, and a protective cover fixed on the U-shaped frame and covering the camera. The camera is fixed in an opening of the U-shaped frame, and avoidance openings are provided at positions corresponding to the shooting end of the camera.

[0021] like Figure 1-3As shown, the utility model provides a paper jam detection device for the fifth wheel of a packaging machine, comprising a cantilever 1, a diffuse reflection arch cover 2 arranged at one end of the cantilever 1, a light source 3 arranged in the diffuse reflection arch cover 2, a camera 4 arranged on the rear side of the diffuse reflection arch cover 2, a first light shielding plate 5 vertically arranged at the lower end of the front side of the diffuse reflection arch cover 2, and a second light shielding plate 6 vertically arranged at the lower end of the outer side of the diffuse reflection arch cover 2, the adjacent sides of the second light shielding plate 6 and the first light shielding plate 5 are fixed and closed, a detection port 7 is arranged at the lower end of the first light shielding plate 5, and the camera 4 is arranged outside the diffuse reflection arch cover 2 and the shooting end is tilted downward toward the bottom of the diffuse reflection arch cover 2.

[0022] Two cameras 2, one color and one black and white, are used. The two cameras 2 are installed side by side and tilted at the same installation angle toward the bottom of the diffuse reflection arch cover 2, the second light shielding plate 6 and the first light shielding plate 5. The diffuse reflection arch cover 2 is fixed to the cigarette packaging machine by a cantilever 1. The light source 3 is inside the diffuse reflection arch cover 2. The camera 4 shoots the bottom of the diffuse reflection arch cover 2. The first light shielding plate 5 and the second light shielding plate 6 are used to block the light, and the unblocked part of the inner side of the diffuse reflection arch cover 2 is opposite to the outer wall of the cigarette packaging machine, which saves costs and blocks light in three directions. The cigarette pack enters from the detection port 7, which can effectively reduce the influence of external light. The light emitted by the light source 3 is scattered by the diffuse reflection arch cover 2 to provide fill light for the camera 4, thereby improving the shooting quality of the camera 4.

[0023] like Figure 1-2 As shown, it also includes a fixed plate 8 and a sliding seat 9 slidably arranged on the fixed plate 8. The other end of the cantilever 1 is arranged on the sliding seat 9. With the help of the sliding seat 9, the cantilever 1 has the freedom of translation.

[0024] By adding an adjustment structure, the position of the diffuse reflection arch cover 2, that is, the detection position, can be adjusted. The horizontal position of the cantilever 1, that is, the position of the diffuse reflection arch cover 2, can be adjusted by moving the sliding seat. After adjustment, it can be locked by bolts and pins, and the locking method is not limited.

[0025] like Figure 1-2 As shown, one end of the cantilever 1 is hinged on the sliding seat 9.

[0026] The diffuse reflection arch cover 2 can be lifted up from the outer side of the diffuse reflection arch cover 2, which is convenient for installation and maintenance.

[0027] like Figure 1-2 As shown, it also includes an articulated seat 10 arranged on the sliding seat 9 and a spring pull rod 11 arranged on the side of the articulated seat 10. One end of the cantilever 1 is hinged on the articulated seat 10, and one end of the spring pull rod 11 is connected to the side of the articulated seat 10, and the other end is connected to the side of the cantilevered end of the cantilever 1.

[0028] The hinge mode is further limited, and a spring pull rod 11 is added, which saves effort when lifting and lowering the diffuse reflection arch cover 2, and the diffuse reflection arch cover 2 is lowered more slowly, avoiding vibration caused by the diffuse reflection arch cover 2 being lowered too fast, thereby preventing damage to the light source 3 and the camera 4.

[0029] like Figure 1-2 As shown, two slide grooves 12 are arranged in parallel on the upper end surface of the fixing plate 8 , and two raised sliders 13 are arranged in parallel on the lower end surface of the sliding seat 9 and are respectively embedded in the slide grooves 12 , and the sliders 13 correspond to and fit with the slide grooves 12 .

[0030] The sliding structure is further limited to make the sliding more stable. The opening width of the slide groove 12 is smaller than the width of the groove bottom, that is, the shrinkage structure can be limited during sliding to prevent the slider 13 and the slide groove 12 from being separated.

[0031] like Figure 1-2 As shown, it also includes a shooting frame, which includes a mounting plate 14 fixed to the diffuse reflection arch cover 2, a U-shaped frame 15 fixed to the mounting plate 14, and a protective cover 16 fixed to the U-shaped frame 15 and covering the camera 4. The camera 4 is fixed in the opening of the U-shaped frame 15, and the protective cover 16 is provided with an avoidance opening at a position corresponding to the shooting end of the camera 4.

[0032] The camera 4 is installed using the mounting plate 14 and the U-shaped frame 15, making installation and maintenance more convenient.

[0033] like Figure 1-2 As shown, two light sources 3 are provided and are respectively and symmetrically located on the inner walls of the front and rear sides of the diffuse reflection arch cover 2, so as to further enhance the fill light effect and improve the photo quality of the camera 4.

[0034] like Figure 1-2 As shown, the diffuse reflection arch cover 2 is an arch structure with an open lower end and closed two sides. The curved side of the diffuse reflection arch cover 2 faces front and back, and the flat side faces inside and outside. One end of the cantilever 1 is fixed to the closed flat side of the diffuse reflection arch cover 2.

[0035] The installation position and orientation of the diffuse reflection arch cover 2 are further limited, which improves the convenience of installation and maintenance, and at the same time improves the shooting quality of the camera 3.
