[0029] Example 1
[0030] As Figure 1As shown, this utility model provides an improved smoke guard plate, including a smoke guard plate base 5, an upper smoke guard plate, and a lower smoke guard plate. The upper and lower smoke guard plates are respectively fixed to the upper and lower surfaces of the smoke guard plate base 5. Both the upper and lower smoke guard plates include a contact portion and a mounting portion. The inner connection between the contact portion and the mounting portion is an obtuse angle, and the outer connection between the contact portion and the mounting portion is a rounded corner. The width of the contact surface between the contact portion of the upper and lower smoke guard plates and the inner lining paper can completely fit the long side of the end face of the inner lining paper. The contact portion is used to support the long side of the end face of the inner lining paper when the short side of the end face is folded.
[0031] The improved cigarette guard plate of this utility model is fully attached to the long side of the inner liner paper end face during the retraction process. While protecting the cigarette, it also supports and protects the long side of the inner liner paper end face. This makes up for the defects of the original design and avoids the quality defects caused by the deformation of the long side due to the folding of the short side of the end face during high-speed operation of the equipment, which leads to poor folding of the short side and the long side of the subsequent workstations, thus ensuring production quality.
[0032] Example 2
[0033] like Figure 1 As shown, this utility model provides an improved smoke guard plate. The improved smoke guard plate comprises four plates: a front upper smoke guard plate 1, a front lower smoke guard plate 2, a rear upper smoke hood guard plate 3, and a rear lower smoke guard plate 4. The front upper smoke guard plate 1 and the front lower smoke guard plate 2 are mounted on the upper and lower surfaces of a smoke guard plate base 5 located on the front side, respectively. The rear upper smoke hood guard plate 3 and the rear lower smoke guard plate 4 are mounted on the upper and lower surfaces of a smoke guard plate base 5 located on the rear side, respectively. Each of the front upper smoke guard plate 1, the front lower smoke guard plate 2, the rear upper smoke hood guard plate 3, and the rear lower smoke guard plate 4 includes a contact portion and a mounting portion. The inner connection is an obtuse angle, and the outer connection between the contact part and the mounting part is a rounded corner. The width of the contact part between the upper and lower smoke guards and the inner lining paper can completely fit the long side of the end face of the inner lining paper. The width of the contact part between the upper and lower smoke guards is 8~12mm, preferably 10mm. After the cigarette and the inner lining paper are pushed into the second wheel 6, the short side folder 7 folds the short side of the end face of the inner lining paper. At this time, the front upper smoke guard 1, the front lower smoke guard 2, the rear upper smoke machine guard 3, and the rear lower smoke guard 4 provide continuous support and protection for the long side of the end face of the inner lining paper while retracting. Figure 2 and Figure 3 ).
[0034] In this embodiment, the rounded corners at the outer connections of the front upper smoke guard plate 1, the front lower smoke guard plate 2, the rear upper smoke machine guard plate 3, and the rear lower smoke guard plate 4 are R4 rounded corners.
[0035] In this embodiment, the mounting part is provided with mounting holes 9, and the smoke guard plate seat is provided with threaded holes. The upper smoke guard plate and the lower smoke guard plate are respectively mounted on the upper and lower surfaces of the smoke guard plate seat 5 by R4 mounting screws 8 passing through the mounting holes 9 and the threaded holes. Figure 4 ).
[0036] In this embodiment, both the mounting part and the smoke guard plate seat 5 are L-shaped, and the mounting holes 9 are provided at the two ends of the L-shaped mounting part respectively.
[0037] In this embodiment, the center of the mounting hole 9 near the contact part and the center of the rounded corner at the outer connection of the mounting part are on different horizontal lines.
[0038] In this embodiment, both the contact portion and the mounting portion are plate-shaped structures.
[0039] In this embodiment, the contact part and the mounting part are fixedly connected or are integrally formed.
[0040] The front upper side smoke guard plate 1, front lower side smoke guard plate 2, rear upper side smoke machine guard plate 3, and rear lower side smoke guard plate 4 of this utility model do not interfere with the short side folding device 7 and the No. 2 wheel 6 of the inner lining paper end face during movement, while completely fitting with the long side of the inner lining paper end face. This protects the key process steps of folding the short side of the inner lining paper end face, resulting in a better folding effect when folding the inner lining paper.
[0041] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model.
