Description

Technical Field

[0001] The utility model relates to the technical field of tipping paper guiding technology, in particular to a multi-specification tipping paper guiding device for PROTOS series cigarette making machines. Background Art

[0002] In the cigarette production process, tipping paper is an important material used to wrap cigarettes and filters to realize the combination of filters and cigarette rods. In the existing process, the tipping paper wraps a group of inner and outer cigarettes at the same time, and then produces two equal-length filter cigarettes after being cut by the second cutting circular knife. The main function of the paper guide block is to realize the transmission and positioning of the tipping paper. With the improvement of cigarette quality requirements, the current technical standard for the length of cigarette tipping paper is -0.5~0.5mm. In order to ensure that the length of the tipping paper of the left and right cigarettes is consistent, the paper guide device is adjustable on the left and right. However, since different brands of cigarettes use tipping paper of different widths, when adjusting the production of different brands of cigarettes, the distance between the left and right paper guide blocks is adjusted to adapt to the different widths of tipping paper auxiliary materials. After the inner and outer paper guide blocks are separated for a certain distance, an empty groove will appear in the middle, and the paper guiding device cannot effectively support the tipping paper. During the operation of the tipping paper, there is no support in the middle and there is pressure on both sides due to the deviation of the paper. Wrinkles will appear in the empty groove in the middle, causing the tipping paper to be uneven and causing quality problems such as wrinkles, bubbles, and air leakage in the tipping paper, which will have an adverse effect on the quality of cigarettes.

[0003] A cross-type tipping paper guide block is disclosed in Chinese patent CN 213622512 U. The tooth-shaped fitting structure of the left and right guide blocks solves the problem that the paper guide device cannot effectively support the tipping paper. However, when adjusting, the position of the right guide block needs to be adjusted first, and then the position of the left guide block needs to be adjusted so that the distance between the two = the tipping paper width + 0.5 mm. In order to ensure that the tipping paper is centered in the center of two long cigarettes, the guide block needs to be adjusted to the center position, so that repeated measurements and adjustments are required during the adjustment process. The adjustment is complicated and restricts the efficiency of production and brand adjustment. Based on this, a paper guide device that can flexibly adapt to the production needs of tipping papers of different specifications and improve the efficiency of production and brand adjustment is needed.

DETAILED DESCRIPTION

[0034] The present invention is further described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0035] Example 1

[0036] like Figure 1-4 As shown, this embodiment provides a multi-specification tipping paper guide device for a PROTOS series cigarette making machine, comprising a rotating shaft 2, a central shaft 3, a scraper 61, a left paper guide block 11 and a right paper guide block 12, wherein the opposite surfaces of the left paper guide block 11 and the right paper guide block 12 are provided with a plurality of tooth-shaped protrusions that can fit each other, so as to solve the problem of supporting multi-specification tipping paper. The rotating shaft 2 passes through the left side wall of the machine and then enters the interior of the left paper guide block 11, and comprises: a knob section 21, a transition section 22 and a threaded section 23, wherein the knob section 21 is located outside the left side wall of the machine, the transition section 22 passes through the left side wall of the machine, and the threaded section 23 extends into the interior of the left paper guide block 11, and the knob section 21, the transition section 22 and the threaded section 23 constitute a platform-shaped shaft structure with successively decreasing diameters, and a first cushion block 24 is installed at the connection between the transition section 22 and the threaded section 23.

[0037] The center shaft 3 is installed on the right side wall of the machine. It passes through the right paper guide block 12 from the right side and then extends into the left paper guide block 11. A screw hole is provided at the end close to the rotating shaft 2. The threaded section 23 is threadedly connected to the screw hole. A second cushion block 32 and a stopper 31 are installed thereon. A spring 5 is provided between the second cushion block 32 and the stopper 31. A shaft sleeve 4 is sleeved on the rotating shaft 2 and the center shaft 3. One side of the shaft sleeve 4 abuts against the first cushion block 24 and the other side abuts against the second cushion block 32. The left paper guide block 11 and the right paper guide block 12 are fixed to the shaft sleeve 4 by a plunger 13 and a fixing bolt 14. By removing the fixing bolt 14 and the plunger 13, the position of the left paper guide block 11 and the right paper guide block 12 on the shaft sleeve 4 can be adjusted so that the left paper guide block 11 and the right paper guide block 12 can adapt to tipping papers of different widths. Figure 3As shown, when the shaft 2 is rotated, it will move along the axial direction under the action of the thread, and under the action of the first cushion block 24, the second cushion block 32 and the spring 5, the sleeve 4 will also produce an axial displacement, thereby achieving the purpose of adjusting the position of the left paper guide block 11 and the right paper guide block in the axial direction. That is, when the shaft 2 moves to the right, the first cushion block 24 is driven to push the sleeve 4 to the right, and the spring 5 is compressed by the second cushion block 32, thereby driving the left paper guide block 11 and the right paper guide block 12 fixed to the sleeve 4 to move to the right, until the tipping paper 7 can be in the middle position between the left paper guide block 11 and the right paper guide block 12. When the shaft 2 is rotated to move to the left, under the action of the rebound force of the spring 5, the sleeve 4 is pushed to the left, so that it still keeps the state of resisting the first cushion block 24 during the movement of the shaft 2, thereby adjusting the position of the left paper guide block 11 and the right paper guide block 12 to the left, until the tipping paper 7 can be in the middle position between the left paper guide block 11 and the right paper guide block 12.

[0038] Furthermore, a limiting groove 33 is provided on the outer surface of the central shaft 3, and the limiting groove 33 is arranged parallel to the axial direction of the central shaft 33.
