Description

Technical Field

[0001] The present invention relates to the technical field of cigarette filter manufacturing and processing, and in particular to a cigarette filter rod paper stripping device and method based on friction. Background Art

[0002] The manufacture of cigarette filters is a crucial step in the cigarette production process. Cigarette filter rods are cut into filter tips. However, during the processing of the filter rods, some unqualified filter rods are inevitably produced. In order to reduce material waste, the acetate fiber in these unqualified filter rods must be recovered and reprocessed. However, the outer surface of the filter rod is usually covered with a layer of wrapping paper. Directly crushing the filter rod will cause paper scraps to mix in, making the raw material impure and therefore unsuitable for reprocessing. On the other hand, although the method of manually peeling off the wrapping paper is feasible, it requires a lot of labor and significantly reduces production efficiency. Summary of the Invention

[0003] The purpose of the present invention is to solve the shortcomings existing in the prior art and propose a friction-based cigarette filter rod stripping device and method. The stripping device can realize the rapid batch stripping of cigarette filter rod wrapping paper, which not only helps to reduce resource waste and improve production efficiency, but also ensures the quality of reprocessed materials, thereby reducing production costs and promoting the sustainable development of the entire cigarette production industry.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] The first rotating friction roller and the second rotating friction roller are installed on the front side of the first vertical conveying mechanism and the second vertical conveying mechanism, and the first rotating friction roller and the second rotating friction roller are symmetrically arranged;

[0008] The horizontal conveying mechanism is arranged at the bottom of the frame and is used to convey the cigarette filter rods with the wrapping paper peeled off.

[0009] Preferably, the first vertical transmission mechanism and the second vertical transmission mechanism have the same structure, and the first vertical transmission mechanism includes a first driving wheel, a first driven wheel, a first driving shaft and a first driven shaft; the first driving wheel is sleeved on the first driving shaft, and the first driving shaft is fixedly mounted on the frame through the first driving shaft bearing seat; the first driven wheel is sleeved on the first driven shaft, and the first driven shaft is movably mounted on the frame through the first driven shaft bearing seat, and the first driven shaft bearing seat is connected to the first threaded tensioning device; the first driving wheel and the first driven wheel are connected by a first synchronous belt.

[0010] Preferably, the second vertical transmission mechanism includes a second driving wheel, a second driven wheel, a second driving shaft and a second driven shaft; the second driving wheel is sleeved on the second driving shaft, and the second driving shaft is fixedly mounted on the frame through a second driving shaft bearing seat; the second driven wheel is sleeved on the second driven shaft, and the second driven shaft is movably mounted on the frame through a second driven shaft bearing seat, and a second threaded tensioning device is connected to the second driven shaft bearing seat; the second driving wheel and the second driven wheel are connected by a second synchronous belt.

[0011] Preferably, the distance between the first synchronous belt and the second synchronous belt is slightly smaller than the diameter of the cigarette filter rod, and the surfaces of the first synchronous belt and the second synchronous belt are both provided with nylon material.

[0012] Preferably, the first rotating friction roller and the second rotating friction roller have the same structure, the cross-sections of the first rotating friction roller and the second rotating friction roller are both circular shaft-shaped, and the diameters of the first rotating friction roller and the second rotating friction roller gradually increase from top to bottom; the first rotating friction roller is connected to the frame through the first rotating friction roller upper bearing seat and the first rotating friction roller lower bearing seat, respectively, and the second rotating friction roller is connected to the frame through the second rotating friction roller upper bearing seat and the second rotating friction roller lower bearing seat, respectively.

[0013] Preferably, the distance between the first rotating friction roller and the second rotating friction roller remains consistent from top to bottom, the distance between the first rotating friction roller and the second rotating friction roller is slightly smaller than the diameter of the cigarette filter rod, and the distance between the first rotating friction roller and the second rotating friction roller is slightly larger than the distance between the first synchronous belt and the second synchronous belt.

[0014] Preferably, the surfaces of the first rotating friction roller and the second rotating friction roller are both covered with silicone material.

[0015] The present invention also provides a method for using a friction-based cigarette filter rod stripping device, comprising the following steps:

[0016] S1. Before peeling the paper, the cigarette filter rod is subjected to surface cutting processing, so that the wrapping paper of the cigarette filter rod is divided into two sections at the middle position;

[0017] S2. The cigarette filter rods that have undergone surface cutting are placed in batches into the feed port. Under the action of gravity, the cigarette filter rods enter the first vertical conveying mechanism and the second vertical conveying mechanism, so that one end of the cigarette filter rod is clamped by the first vertical conveying mechanism and the second vertical conveying mechanism, and the other end of the cigarette filter rod contacts the first rotating friction roller and the second rotating friction roller; under the clamping and conveying of the first vertical conveying mechanism and the second vertical conveying mechanism, the cigarette filter rods move from top to bottom. During this process, the relative sliding speed of the part in contact with the first rotating friction roller and the second rotating friction roller increases linearly, so that the friction force is linearly increased, so that the filter rod wrapping paper at one end of the cigarette filter rod is peeled off; the cigarette filter rod with half of the wrapping paper peeled off reaches the bottom of the vertical conveying mechanism and falls onto the conveyor belt of the horizontal conveying mechanism, and is then conveyed out;

[0018] S3. Put the cigarette filter rod with half of the wrapping paper peeled off back into the feed port. At this time, the position of the cigarette filter rod is opposite to that at the beginning, so that the first vertical conveying mechanism and the second vertical conveying mechanism clamp the end of the cigarette filter rod with the wrapping paper peeled off, and the end with the wrapping paper remaining contacts the first rotating friction roller and the second rotating friction roller, thereby peeling off the remaining half of the wrapping paper of the cigarette filter rod, and finally obtaining the cigarette filter rod with the wrapping paper completely peeled off.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The paper stripping device of the present invention utilizes the principle of friction to efficiently strip the wrapping paper of the cigarette filter rod. By using a rotating friction roller, the friction force gradually increases as the cigarette filter rod is conveyed from top to bottom, ensuring that the wrapping paper of the cigarette filter rod can be stripped quickly and effectively.

This is expected to bring significant improvements and competitive advantages to the cigarette manufacturing industry. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Reference Figure 1-5 A friction-based cigarette filter rod stripping device includes a frame 2, a feed port 3 provided on the frame 2, a first vertical conveying mechanism 4, a second vertical conveying mechanism 5, a first rotating friction roller 6, a second rotating friction roller 7, and a horizontal conveying mechanism 10 provided on the frame 2;

[0029] The first vertical conveying mechanism 4 and the second vertical conveying mechanism 5 are vertically installed side by side on the frame 2. The first vertical conveying mechanism 4 and the second vertical conveying mechanism 5 are arranged symmetrically, and the first vertical conveying mechanism 4 and the second vertical conveying mechanism 5 are arranged below the feed port 3;

[0030] The first rotating friction roller 6 and the second rotating friction roller 7 are installed on the front side of the first vertical conveying mechanism 4 and the second vertical conveying mechanism 5, and the first rotating friction roller 6 and the second rotating friction roller 7 are symmetrically arranged;

[0031] The horizontal conveying mechanism 10 is provided at the bottom of the frame 2 and is used to convey the cigarette filter rods after the wrapping paper is peeled off.

[0032] Specifically, refer to Figure 3-Figure 4 The first vertical transmission mechanism 4 and the second vertical transmission mechanism 5 have the same structure. The first vertical transmission mechanism 4 includes a first driving wheel 42, a first driven wheel 41, a first driving shaft 44 and a first driven shaft 45; the first driving wheel 42 is sleeved on the first driving shaft 44, and the first driving shaft 44 is fixedly installed on the frame 2 through the first driving shaft bearing seat; the first driven wheel 41 is sleeved on the first driven shaft 45, and the first driven shaft 45 is movably installed on the frame 2 through the first driven shaft bearing seat 49, and the first driven shaft bearing seat 49 is connected to the first threaded tensioning device 48; the first driving wheel 42 and the first driven wheel 41 are connected by a first synchronous belt 43.

[0033] Specifically, refer to Figure 4 The second vertical transmission mechanism 5 includes a second driving wheel 52, a second driven wheel 51, a second driving shaft 54 ​​and a second driven shaft 55; the second driving wheel 52 is sleeved on the second driving shaft 54, and the second driving shaft 54 ​​is fixedly mounted on the frame 2 through a second driving shaft bearing seat; the second driven wheel 51 is sleeved on the second driven shaft 55, and the second driven shaft 55 is movably mounted on the frame 2 through a second driven shaft bearing seat 59, and a second threaded tensioning device 58 is connected to the second driven shaft bearing seat 59; the second driving wheel 52 and the second driven wheel 51 are connected by a second synchronous belt 53.

[0034] Specifically, the distance between the first synchronous belt 43 and the second synchronous belt 53 is slightly smaller than the diameter of the cigarette filter rod 1 , and the surfaces of the first synchronous belt 43 and the second synchronous belt 53 are both provided with nylon material.

[0035] In this embodiment, nylon material is used on the surfaces of the first synchronous belt 43 and the second synchronous belt 53, thereby increasing the surface friction of the first synchronous belt 43 and the second synchronous belt 53; by rotating the first threaded tensioning device 48, the first driven shaft bearing seat 49 can be fine-tuned up and down in the slide groove, thereby achieving the tensioning of the first synchronous belt 43; similarly, by rotating the second threaded tensioning device 58, the second driven shaft bearing seat 59 can be fine-tuned up and down in the slide groove, thereby achieving the tensioning of the second synchronous belt 53; here, the first driving shaft 44 of the first vertical transmission mechanism 4 and the second driving shaft 54 ​​of the second vertical transmission mechanism 5 achieve the same speed and opposite direction through a pair of gears, so that the conveying speeds of the first synchronous belt 43 and the second synchronous belt 53 are completely consistent, ensuring that the cigarette filter rod will not roll during the clamping and conveying process, that is, the rotation direction of the first synchronous belt 43 and the second synchronous belt 53 is as follows Figure 1 As shown, the directions are opposite, from outside to inside, and the spacing between the first synchronous belt 43 and the second synchronous belt 53 is slightly smaller than the diameter of the cigarette filter rod 1, so that the cigarette filter rod is kept clamped during the conveying process from top to bottom of the vertical conveying mechanism.

[0036] Specifically, refer to Figure 2 The first rotating friction roller 6 and the second rotating friction roller 7 have the same structure. The cross-sections of the first rotating friction roller 6 and the second rotating friction roller 7 are both circular shaft-shaped, and the diameters of the first rotating friction roller 6 and the second rotating friction roller 7 gradually increase from top to bottom; the first rotating friction roller 6 is connected to the frame 2 through the first rotating friction roller upper bearing seat 61 and the first rotating friction roller lower bearing seat 62, respectively, and the second rotating friction roller 7 is connected to the frame 2 through the second rotating friction roller upper bearing seat 71 and the second rotating friction roller lower bearing seat 72, respectively.

[0037] Specifically, the distance between the first rotating friction roller 6 and the second rotating friction roller 7 remains consistent from top to bottom, the distance between the first rotating friction roller 6 and the second rotating friction roller 7 is slightly smaller than the diameter of the cigarette filter rod 1, and the distance between the first rotating friction roller 6 and the second rotating friction roller 7 is slightly larger than the distance between the first synchronous belt 43 and the second synchronous belt 53.

[0038] The surfaces of the first rotating friction roller 6 and the second rotating friction roller 7 are both covered with silicone material.

[0039] In this embodiment, the first rotating friction roller 6 and the second rotating friction roller 7 are installed on the front side of the first vertical conveying mechanism 4 and the second vertical conveying mechanism 5, and their rotation speeds are the same, and the rotation directions are as follows: Figure 1 As shown; by covering the surfaces of the first rotating friction roller 6 and the second rotating friction roller 7 with a silicone material to increase friction; the installation angle position of the first rotating friction roller 6 and the second rotating friction roller 7 is as shown Figure 2 , keep the distance between the first rotating friction roller 6 and the second rotating friction roller 7 consistent from top to bottom, the distance between the first rotating friction roller 6 and the second rotating friction roller 7 is slightly smaller than the diameter of the cigarette filter rod 1, and the distance between the first rotating friction roller 6 and the second rotating friction roller 7 is slightly larger than the distance between the first synchronous belt 43 and the second synchronous belt 53. The design of such an outer structure and installation angle is to make the cigarette filter rod be conveyed from top to bottom. As the linear speed of the rotating friction roller surface from top to bottom becomes larger and larger, the relative sliding speed between the rotating friction roller surface and the cigarette filter rod also becomes larger and larger, resulting in an increase in friction force. Therefore, in the process of downward conveying of the cigarette filter rod, the wrapping paper of the cigarette filter rod is removed by relying on the friction force brought by the rotating friction roller.

[0040] Reference Figure 1 、 Figure 5 A method for using a friction-based cigarette filter rod stripping device comprises the following steps:

[0041] S1. Before peeling the paper, the cigarette filter rod is subjected to surface cutting processing, so that the wrapping paper of the cigarette filter rod is divided into two sections at the middle position;

[0042] S2. The cigarette filter rods 1 that have undergone surface cutting are put into the feed port 3 in batches. Under the action of gravity, the cigarette filter rods enter the first vertical conveying mechanism 4 and the second vertical conveying mechanism 5, so that one end of the cigarette filter rod is clamped by the first vertical conveying mechanism 4 and the second vertical conveying mechanism 5, and the other end of the cigarette filter rod contacts the first rotating friction roller 6 and the second rotating friction roller 7; under the clamping and conveying of the first vertical conveying mechanism 4 and the second vertical conveying mechanism 5, the cigarette filter rods move from top to bottom. During this process, the relative sliding speed of the part in contact with the first rotating friction roller 6 and the second rotating friction roller 7 increases linearly, so that the friction force is linearly increased, so that the filter rod wrapping paper 8 at one end of the cigarette filter rod is peeled off; the cigarette filter rod 9 with half of the wrapping paper peeled off reaches the bottom of the vertical conveying mechanism and falls onto the conveyor belt of the horizontal conveying mechanism 10, and is then conveyed out;

[0043] S3. Put the cigarette filter rod 9 with half of the wrapping paper peeled off back into the feed port 3. At this time, the position of the cigarette filter rod is opposite to that at the beginning, so that the first vertical conveying mechanism 4 and the second vertical conveying mechanism 5 clamp the end of the cigarette filter rod with the wrapping paper peeled off, and the end with the wrapping paper remaining contacts the first rotating friction roller 6 and the second rotating friction roller 7, thereby peeling off the remaining half of the wrapping paper of the cigarette filter rod, and finally obtaining the cigarette filter rod 11 with the wrapping paper completely peeled off.

[0044] In summary, the present invention utilizes the friction principle to efficiently peel off the wrapping paper of the cigarette filter rod. By using a rotating friction roller, as the cigarette filter rod is transmitted from top to bottom, the friction force gradually increases, ensuring that the wrapping paper of the cigarette filter rod can be peeled off quickly and effectively.

[0045] The descriptions and practices disclosed in this invention are easy to understand and comprehend for those skilled in the art, and modifications and refinements may be made without departing from the principles of the invention. Therefore, modifications and improvements made without departing from the spirit of the invention should also be considered within the scope of protection of this invention.
