Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a paper winder, and more particularly, to one in which a paper cutting board is pivotally supported across opposing left and right side plates.

<Prior Art> Conventionally, in this type of cigarette roll machine, after the left and right side plates are fixed facing each other in advance, a paper cutting plate is attached between them, for example, as shown in Fig. 5.
As disclosed in Japanese Patent No. 39640, the rear end of the paper-cutting plate 11 is bent into an annular shape to form a cylindrical part 12, and the left and right ends of the cylindrical part 12 are screwed from the outer surfaces of the left and right side plates 13, 13. The paper cutting board 11 was pivotally supported by inserting the ends of screws 14, 14, respectively.

Therefore, in the case of Utility Model Publication No. 52-39640, the heads of the screws 14, 14 are exposed on the outer surfaces of the left and right side plates 13, 13, which not only has a bad appearance, but also imposes large restrictions on the design of the cigarette holder body 15. It was something to give.

<Problem to be Solved by the Invention> The problem to be solved by the invention is to pivotally support the paper cutting board without exposing the fixtures to the outer surfaces of the left and right side plates.

<Means for Solving the Problems> The technical means taken by the present invention to solve the above problems is to place support rods on the left and right sides in a cylindrical part formed by bending the rear end of a paper cut plate into an annular shape. Insert it so that it can move laterally,
Both ends of this support rod are inserted into bearing holes recessed in the left and right side plates of the paper winder main body, respectively, to rotatably support the paper cutting board, and a part of the cylindrical portion is cut out. The support rod is partially exposed, the support rod is formed to be longer than the dimension between the left and right side plates and shorter than the dimension between the bottom surfaces of the left and right bearing holes, and a lateral movement prevention means is removably provided at an appropriate position. This is a characteristic feature.

<Function> The function of the present invention is to insert one end of the support rod inserted into the cylindrical part deep into one of the bearing holes, and move the support rod laterally to the other bearing hole using a finger or the like through the notch in the cylindrical part. The paper-cutting plate is rotatably supported by inserting the paper-cutting board into the hole and by attaching a lateral movement prevention means to the support rod to prevent the support rod from moving laterally.

<Example> Hereinafter, an example of the present invention will be described based on the drawings.

In this embodiment, as shown in FIG.
This figure shows a case in which side plates A ₂ and A ₂ are integrally provided on both left and right sides of a back plate A ₁ in a U-shape in plan, made of a material such as ceramics.

In the inner surfaces of the left and right side plates A ₂ and A ₂ , opposing bearing holes 1 and 1 are recessed uniaxially, respectively, and a paper cutting plate 2 is installed between these left and right bearing holes 1 and 1 .

The paper-cutting plate 2 is a metal plate of a conventionally well-known shape, and its width is shorter than the inner dimension between the left and right side plates A ₂ and A ₂ , and its rear end is bent downward into an annular shape to form a cylindrical part 2a. , the support rod 3 is inserted into the cylindrical portion 2a, and a notch 2b is formed in a part of the cylindrical portion 2a, in the center in this embodiment, and a part of the support rod 3 is exposed from this notch 2b. .

Note that the position where the notch 2 is formed is not limited to the center, but may be formed anywhere on the cylindrical portion 2a.

The support rod 3 is a metal rod made of stainless steel, etc., and has a diameter smaller than the inner diameter of the bearing holes 1, 1 and the inner diameter of the cylindrical part 2a, and its length is longer than the inner dimension between the left and right side plates _A2 , _A2 . Moreover, by forming the inner dimension shorter than the inner dimension between the bottom surfaces of the left and right bearing holes 1, 1, the other end can be inserted into and taken out from the other bearing hole 1 while one end is inserted deep into one bearing hole 1.

Further, a lateral movement preventing means 4 is detachably provided at an appropriate position on the support rod 3.

In this embodiment, the lateral movement prevention means 4 includes a guide groove 4a recessed in the outer peripheral surface of the support rod 3;
and an E-type retaining ring 4b that is removably fitted to the side plate 4b when the guide groove 4a is installed
It is formed to correspond to the gap formed between A ₂ and the cylindrical portion 2a.

Next, the procedure for attaching the paper cutting board 2 to the left and right side plates A ₂ and A ₂ will be explained.

First, as shown in FIG. 3, the cylindrical part 2a of the paper cutting board 2 is
Insert the support rod 3 inside, and connect only one end to the cylindrical part 2.
a and insert it all the way into one of the bearing holes 1.

Then, the cylindrical portion 2a is rotated around one end of the inserted support rod 3, and the other end of the cylindrical portion 2a and the other bearing hole 1 are uniaxially opposed, as shown in FIG. Insert a finger or the like into the notch 2b to move the support rod 3 laterally toward the other bearing hole 1, and insert the other end of the support rod 3 into the bearing hole 1 to pivot the paper cutting plate 2. do.

Furthermore, the support rod 3 is moved laterally to separate the side plate A ₂ and the cylindrical part 2.
When the guide groove 4a appears between the guide groove 4a and the guide groove 4a, the lateral movement is stopped, and an E-shaped retaining ring 4b is attached to the guide groove 4a to prevent the support rod 3 from lateral movement.

In addition, in the case of this embodiment, bushes 5 formed in a cylindrical shape with a cushioning material such as hard polyethylene are provided at the open ends of the left and right bearing holes 1, 1 and at both end openings of the cylindrical portion 2a.
The flange portions 5a protruding from the outer periphery of the tips of the bushes 5 are disposed between the side plates A ₂ , A ₂ and the cylindrical portion 2a, and the side plates A ₂ , A ₂ and the cylindrical portion 2a are fitted together. By preventing the portion 2a and the cylindrical portion 2a from coming into direct contact with the support rod 3, noise is not generated even if the paper cutting board 2 vibrates during use.

In the above embodiment, the lateral movement prevention means 4 was composed of the guide groove 4a and the E-shaped retaining ring 4b, but it is not limited to this, and any structure can be used as long as it can prevent the lateral movement of the support rod 3. Furthermore, the recessed position of the guide groove 4a is not limited to the above-mentioned position, but may be recessed at any position such as corresponding to the inside of the notch 4b.

<Effects of the Invention> Since the present invention has the above configuration, it has the following advantages.

Insert one end of the support rod that has been inserted through the cylindrical part into one of the bearing holes all the way, and use your fingers or the like to move the support rod laterally from the notch in the cylindrical part to the other bearing hole and insert it into the hole. By attaching a lateral movement prevention means to the support rod to prevent the support rod from moving laterally, the paper-cutting board was rotatably supported, and the screw heads were attached to the outer surfaces of the left and right side plates, unlike conventional ones. Not only is the appearance improved because the paper roll is not exposed, but the design of the paper roll body is not restricted and can be designed freely.
