Abstract
Description
Technical Field
[0001] This utility model relates to the field of auxiliary technology for the production of coiling machines, and in particular to a smoke removal device. Background Technology
[0002] Due to its stable performance, high operating rate, good cigarette quality, and convenient maintenance, the ZJ118 cigarette making machine has become one of the mainstream models in my country's tobacco industry. During operation, the ZJ118 cigarette making machine's rollers rotate at high speed to attach cigarettes. Cigarettes typically need to be rubbed together by the rubbing drum and rubbing plate. During the rubbing process, tobacco dust is squeezed out of the cigarette. With the high-speed rotation of the equipment, the tobacco dust floats between the rollers and easily adheres to the glued tipping paper. Ultimately, it gets stuck between the cigarette tip stick and the tipping paper, forming a "cigarette dust trap" quality defect.
[0003] In the existing technology, the original method was to install a negative pressure chamber above the drum, which is connected to a negative pressure air source. The negative pressure air would adsorb the surrounding smoke particles. However, in the high-speed production process of the cigarette making machine, the removal by a single adsorption method is not complete. Due to the high initial velocity of the smoke particles, some smoke particles directly pass through the adsorption zone. Utility Model Content
[0004] In view of this, the purpose of this utility model is to provide a smoke removal device that solves the problem in the prior art where the initial velocity of the smoke is high, the single adsorption method is not completely effective in removing it, and some smoke directly passes through the adsorption zone.
[0005] This utility model solves the above-mentioned technical problems through the following technical means: a smoke removal device, installed inside the body of a cigarette rolling machine, comprising:
[0006] The suction plate is disposed between the close-up drum and the joint drum. The suction plate has a first suction hole and a second suction hole arranged in parallel along the height direction of the suction plate. The first negative pressure in the first suction hole is greater than the second negative pressure in the second suction hole.
[0007] The first guide plate and the second guide plate are respectively disposed on both sides of the suction plate. One end of the first guide plate is connected to the top of the first suction hole, and the other end extends to the tangential direction of the smoke dispersion trajectory of the rubbing drum. The second guide plate is disposed below the suction plate, with one end close to the second suction hole and the other end extending along the outer contour of the drum to the converging drum, for collecting the settled smoke.
[0008] A blower block is positioned directly above the rubbing drum. The blower block has blower slots. The opening direction of the blower slots is parallel to the end direction of the first guide plate near the rubbing drum. This is used to cooperate with the first guide plate to form a directional airflow channel for collecting scattered smoke particles.
[0009] Optionally, the diameter of the first suction hole is 0.8-1.2 mm and the hole spacing is 1.5-2 mm, and the diameter of the second suction hole is 2-3 mm and the hole spacing is 3-4 mm.
[0010] Optionally, the end of the first guide vane is provided with a curved surface, and the extension length of the curved surface accounts for 1 / 3 to 1 / 2 of the total length of the first guide vane.
[0011] Optionally, the outlet of the blower slot is provided with a mesh hole, the mesh hole having a diameter of 0.5-0.8mm.
[0012] Optionally, the bottom of the blower block is provided with a guide protrusion, and the guide protrusion is provided with an inclined surface with an angle of 45°-60°. The extension direction of the inclined surface forms an angle of 15°-30° with the tangential direction of the approaching drum.
[0013] Optionally, a lower foam suction cover located at the bottom of the machine body is also included.
[0014] The beneficial effects of this utility model are:
[0015] This invention achieves gradient negative pressure adsorption by setting up double rows of different diameter air intake holes on the air intake plate. Together with the first guide plate and the second guide plate, they form corresponding airflow channels, so that large particles of settled smoke are adsorbed by the second air intake hole, and small particles of scattered smoke are adsorbed by the first air intake hole.

[0022] like Figures 1-3 As shown, this utility model discloses a smoke removal device, which is installed inside the body of a cigarette rolling machine. It includes a suction plate 4 positioned between the closing drum 1 and the twisting drum 2. The suction plate 4 has a first suction hole 41 and a second suction hole 42 arranged parallel to each other along its height. The first negative pressure in the first suction hole 41 is greater than the second negative pressure in the second suction hole 42. For example, the diameter of the first suction hole 41 is 0.8-1.2 mm and the hole spacing is 1.5-2 mm, used to collect scattered smoke particles, which are relatively light and have finer particles. For example, the diameter of the second suction hole 42 is 2-3 mm and the hole spacing is 3-4 mm, used to collect settled smoke particles, which are relatively large and have larger particles.
[0023] In this embodiment, the smoke removal device includes a first guide plate 43 and a second guide plate 44 disposed on both sides of the suction plate 4. One end of the first guide plate 43 is connected above the first suction hole 41, and the other end extends to the tangential direction of the smoke dispersion trajectory of the rubbing drum 2. The second guide plate 44 is disposed below the suction plate 4, with one end close to the second suction hole 42 and the other end extending along the outer contour of the approaching drum 1 to the approaching converging drum 3, for collecting settled smoke.
[0024] In this embodiment, the smoke removal device includes a blowing block 5 disposed above the rubbing drum 2. The blowing block 5 has a blowing slot 51. The opening direction of the blowing slot 51 is parallel to the end direction of the first guide plate 43 near the rubbing drum 2, which is used to cooperate with the first guide plate 43 to form a directional airflow channel for collecting scattered smoke.
[0025] In this embodiment, the end of the first guide plate 43 is provided with a curved surface, which is the end near the suction plate 4. For example, the radius of curvature R of the curved surface is 6-10mm, and the extension length of the curved surface accounts for 1 / 3-1 / 2 of the total length of the guide plate. The curved surface at the end of the first guide plate, the arc-shaped guide part, controls the airflow direction and transforms the linear motion trajectory of the high-speed scattered smoke into centrifugal motion, thereby increasing the residence time of the smoke in the adsorption area of the first suction hole 41. At the same time, some of the scattered smoke that is not adsorbed by the first suction hole 41 in time settles to the area of the second guide plate 44 near the suction plate 4 and is adsorbed and removed by the second suction hole 42.
[0026] In this embodiment, a mesh hole with a diameter of 0.5-0.8 mm is provided at the outlet of the air-blowing slot 51. A guide boss 52 is provided at the bottom of the air-blowing block 5. For example, the guide boss 52 has an inclined surface with an angle of 45°-60°, a height of 3-5 mm, and its extension direction forms an angle of 15°-30° with the tangent direction of the approaching drum 1. The height of the guide boss, and the angle between it and the axis of the air-blowing slot, are used to guide the airflow direction, enhance the blowing effect, and avoid airflow turbulence.
[0027] In this embodiment, the smoke removal device further includes a lower smoke suction hood 6 disposed at the bottom of the machine body. The lower smoke suction hood 6 is connected to a negative pressure air source and is used to collect residual settled smoke generated at the bottom or top of the drum.
[0028] It is important to understand that the first suction port 41 and the second suction port 42 are connected to different negative pressure air sources, while the blowing slot 51 is connected to a positive pressure air source. The corresponding negative pressure and positive pressure air sources, such as the two common types of fans, are equipped with necessary components like pipes and valves, which will not be elaborated further.
[0029] The working principle of this utility model is as follows:
[0030] This utility model discloses a dust removal device for smoke and dust, which is installed inside the body of a winding and joining machine. A suction plate 4 is positioned between the approach drum 1 and the joining drum 2. The suction plate 4 has a first suction hole 41 and a second suction hole 42 arranged parallel to each other along its height. One end of a first guide plate 43 is connected above the first suction hole 41, and the other end extends to the tangent direction of the smoke and dust dispersion trajectory of the joining drum 2. A blowing block 5 is positioned directly above the approach drum 1 and has a blowing slot 51. The opening direction of the blowing slot 51 is parallel to the end direction of the first guide plate 43 near the joining drum 2, forming a directional airflow channel to collect the dispersed smoke and dust. A second guide plate 44 is positioned below the suction plate 4, with one end near the second suction hole 42 and the other end extending along the outer contour of the approach drum 1 to near the converging drum 3, for collecting settled smoke and dust.
[0031] During this process, some of the scattered smoke droplets that were not promptly absorbed by the first suction hole 41 settle down to the area near the suction plate 4 on the second guide plate 44 and are absorbed and removed by the second suction hole 42.
[0032] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model. Technologies, shapes, and structural parts not described in detail in this utility model are all known technologies.
