Description

Technical Field

[0001] This utility model relates to the field of tobacco manufacturing equipment technology, and in particular to a twisting assembly and a cigarette rolling machine. Background Technology

[0002] In the existing cigarette manufacturing process, wrinkles often appear on the surface of cigarettes. According to investigations, this problem mainly occurs during the cigarette splicing stage.

[0003] If the tipping paper does not make sufficient contact with the cigarette during this stage, or if it comes loose during the turning process, wrinkles will appear.

[0004] Furthermore, the reasons for the above problems are due to insufficient friction provided by the washboard and insufficient suction force of the drum roller on the cigarette.

[0005] Furthermore, it was found that when the upstream equipment was first started, its operation was unstable. The waste cigarettes it produced could easily clog the air holes of the drum during the rubbing process, preventing the drum from firmly adhering to the cigarettes. In addition, the powder from the waste cigarettes covered the rubbing plate, reducing the friction between the rubbing plate and the cigarettes.

[0006] Therefore, there is an urgent need for a twisting assembly and a cigarette rolling machine to solve the above-mentioned technical problems. Utility Model Content

[0007] The purpose of this invention is to provide a kneading assembly and a cigarette rolling machine that can reduce the probability of drum blockage, maintain the continuity of the kneading process, maintain the stability of equipment operation, and improve production efficiency.

[0008] To achieve this objective, the present invention adopts the following technical solution:

[0009] The splicing assembly includes:

[0010] The air valve has a first air port A and a first air port B, which can generate negative pressure airflow;

[0011] The drum is fitted over the air valve and can rotate around the axis relative to the air valve. The drum is provided with a second air port group, which adsorbs the cigarette assembly through the negative pressure airflow.

[0012] A wind deflector is installed on the aforementioned air valve. The wind deflector has a third air port. A solenoid valve is installed at part of the third air port. The third air port includes a first state and a second state. When it is in the first state, the solenoid valve is open, and the first air port B can communicate with the second air port group through the third air port. When it is in the second state, the solenoid valve is closed, and the third air port blocks the communication between the first air port B and the second air port group.

[0013] The washboard is located downstream of the windbreak component. The first end face of the washboard faces the drum, and the first end face is provided with an anti-slip structure.

[0014] As a preferred technical solution of the above-mentioned splicing assembly, the side of the wind deflector facing away from the air valve is an arc surface, which can fit against the inner peripheral wall of the drum.

[0015] As a preferred technical solution for the above-mentioned splicing assembly, the windbreak is fixed to the air valve by threaded fasteners.

[0016] As a preferred technical solution of the above-mentioned rubbing assembly, the first end face of the rubbing plate is provided with a guide bar, and the length direction of the guide bar is parallel to the axial direction of the drum.

[0017] As a preferred technical solution for the above-mentioned splicing assembly, multiple guide bars are provided, and the multiple guide bars are arranged in parallel.

[0018] As a preferred technical solution for the above-mentioned rubbing assembly, a heating element is provided inside the rubbing plate.

[0019] As a preferred technical solution for the above-mentioned splicing assembly, the anti-slip structure is toothed.

[0020] As a preferred technical solution of the above-mentioned splicing assembly, the above-mentioned air valve has an installation groove, and the above-mentioned wind baffle is embedded in the above-mentioned installation groove.

[0021] As a preferred technical solution of the above-mentioned splicing assembly, it also includes an exhaust valve, which is installed on the air valve. The exhaust valve has a fourth air port, which can generate a positive pressure airflow. The positive pressure airflow is used to clear the second air port group.

[0022] A cigarette rolling machine is also provided, including the aforementioned twisting assembly.

[0023] The beneficial effects of this utility model are:

[0024] This utility model provides a cigarette-making assembly and a cigarette-making machine. The assembly includes an air valve, a drum, a baffle, and a rubbing plate. The air valve has two openings, a first air port A and a first air port B, which generate negative pressure airflow. The drum is fitted around the air valve and can rotate relative to it. The drum has a second air port group that uses the negative pressure airflow to adsorb the cigarette assembly. The baffle is installed on the air valve and has a third air port. A solenoid valve is installed at the third air port. The third air port has a first state and a second state. In the first state, the solenoid valve is open, allowing the first air port B to communicate with the second air port group through the third air port. In the second state, the solenoid valve is closed, and the third air port blocks the communication between the first air port B and the second air port group. The rubbing plate is located downstream of the baffle, with its first end face facing the drum. The first end face has an anti-slip structure.

[0025] For example, the air valve is relatively fixed, with a through hole in the middle. The outer peripheral wall of the air valve has a first air port A and a first air port B. When the air valve is activated, a negative pressure airflow is generated, which flows from outside the air valve into its interior. A drum is sleeved outside the air valve and fixed to a rotating shaft inserted into the through hole. When the rotating shaft rotates around its own axis, the drum rotates with it. The outer peripheral wall of the drum has slits for adsorbing cigarettes. The length of the slits is parallel to the axial direction of the drum, and the depth of the slits is parallel to the radial direction of the drum. Multiple slits are provided, evenly distributed around the axis of the drum. The second air port group of the drum includes a second air port A and a second air port B. The second air port A is located on the bottom wall of the slit and is used to adsorb cigarettes, while the second air port B is located on the opening end face of the slit and is used to adsorb tipping paper. The rubbing board is located on the radial side of the drum. The rubbing board is fixed relative to the air valve. The first end face of the rubbing board is arc-shaped and fits the outer wall of the drum. When the cigarette and tipping paper are transported to the corresponding area of ​​the rubbing board, the two rotate relative to each other because the rubbing board remains stationary while the drum rotates. The cigarette is wrapped by the tipping paper. The anti-slip structure on the surface of the rubbing board can increase the friction and reduce the wrinkles generated during the cigarette twisting process.

[0026] Furthermore, since the upstream supporting equipment is not stable when it is first started, it is easy to produce waste cigarettes. Waste cigarettes can easily cause blockage of the second air port group during the splicing process, requiring the machine to be stopped for cleaning. Therefore, in this embodiment, a baffle is installed upstream of the corrugated plate. This baffle selectively blocks the connection between the first air port B and the second air port group. Specifically, the first air port A is located upstream of the first air port B. When the second air port group connects with the first air port A, the drum has suction capacity and can obtain cigarette assemblies from the upstream feeding device. If in the initial startup state, to remove defective cigarettes, the solenoid valve of the baffle is closed, preventing the second air port group from obtaining negative pressure airflow when it rotates to the first air port B. The drum loses suction, and the cigarette assembly separates from the drum before entering the corrugated plate, no longer entering the corrugating process. After a period of time, the equipment is considered to be running stably. At this time, the solenoid valve opens, allowing the second air port group to still obtain negative pressure airflow when it rotates to the first air port B, enabling the cigarette assembly to enter the corrugated plate for the corrugating process. This maintains the continuity of the corrugating process, ensures the stability of the equipment operation, and thus improves production efficiency. Attached Figure Description

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0037] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0038] like Figure 1As shown, this utility model provides a rubbing assembly, including: an air valve 100, a drum 200, a wind deflector 300, and a rubbing plate 400. The damper 100 has a first air port A110 and a first air port B120, which can generate negative pressure airflow. The drum 200 is fitted around the damper 100 and can rotate around the axis relative to the damper 100. The drum 200 has a second air port group 210, which adsorbs the cigarette assembly through the negative pressure airflow. The wind deflector 300 is installed on the damper 100 and has a third air port. A solenoid valve is installed at the third air port. The third air port has a first state and a second state. When it is in the first state, the solenoid valve is open, and the first air port B120 can communicate with the second air port group 210 through the third air port. When it is in the second state, the solenoid valve is closed, and the third air port blocks the communication between the first air port B120 and the second air port group 210. The washboard 400 is located downstream of the wind deflector 300. The first end face of the washboard 400 is directly opposite the drum 200, and the first end face is provided with an anti-slip structure 410.

[0039] For example, the air valve 100 is relatively fixed, and a through hole is opened in the middle of the air valve 100. The outer peripheral wall of the air valve 100 is provided with a first air port A110 and a first air port B120. When the air valve 100 is started, a negative pressure airflow is generated. The negative pressure airflow, i.e., the airflow, flows from the outside of the air valve 100 into the inside of the air valve 100. The drum 200 is sleeved on the outside of the air valve 100. The drum 200 is fixed to the rotating shaft inserted in the through hole. When the rotating shaft rotates around its own axis, the drum 200 rotates together with the rotating shaft. The outer peripheral wall of the drum 200 has slits for adsorbing cigarettes. The length direction of the slits is parallel to the axial direction of the drum 200, and the depth direction of the slits is parallel to the radial direction of the drum 200. Multiple slits are provided and are evenly distributed around the axis of the drum 200. The second air port group 210 of the drum 200 includes a second air port A and a second air port B. The second air port A is opened on the bottom wall of the slit and is used to adsorb cigarettes. The second air port B is opened on the opening end face of the slit and is used to adsorb tipping paper. The rubbing board 400 is located on the radial side of the drum 200. The rubbing board 400 is relatively fixed to the air valve 100. The first end face of the rubbing board 400 is arc-shaped and fits the outer side wall of the drum 200. When the cigarette and the tipping paper are transported to the corresponding area of ​​the rubbing board 400, since the rubbing board 400 remains stationary while the drum 200 continues to rotate, the two rotate relative to each other. The cigarette is wrapped by the tipping paper. The anti-slip structure 410 on the surface of the rubbing board 400 can increase the friction and reduce the wrinkles generated during the cigarette twisting process.

[0040] Furthermore, since the upstream supporting equipment is not stable when it is first started, it is easy to generate defective cigarettes. Defective cigarettes can easily cause blockage of the second air port group 210 during the splicing process, requiring a shutdown for cleaning. Therefore, in this embodiment, a baffle 300 is installed upstream of the washboard 400. The baffle 300 can selectively block the connection between the first air port B120 and the second air port group 210. Specifically, the first air port A110 is located upstream of the first air port B120. When the second air port group 210 is connected to the first air port A110, the drum 200 has an adsorption capacity and can obtain cigarette assemblies from the upstream feeding device. If it is in the initial start-up state, in order to remove defective cigarettes, the baffle 300... When the solenoid valve closes, the second air inlet group 210 cannot obtain negative pressure airflow when it rotates to the first air inlet B120. The drum 200 loses suction, and the cigarette assembly separates from the drum 200 before entering the rubbing plate 400, thus ceasing the rubbing process. After a period of time, the equipment is considered to be operating stably. At this point, the solenoid valve opens, allowing the second air inlet group 210 to still obtain negative pressure airflow when it rotates to the first air inlet B120, enabling the cigarette assembly to enter the rubbing plate 400 for the rubbing process. This maintains the continuity of the rubbing process, ensures the stability of equipment operation, and ultimately improves production efficiency.

[0041] It should be noted that the specific cigarette-rolling process is existing technology and will not be described in detail here.

[0042] Optionally, the side of the wind deflector 300 facing away from the air valve 100 is an arc surface, which can fit against the inner peripheral wall of the drum 200.

[0043] For example, the wind deflector 300 includes a first sidewall for tightly abutting against the air valve 100 and a second sidewall for tightly abutting against the inner peripheral wall of the drum 200. Since the drum 200 needs to rotate relative to the air valve 100 when transporting the cigarette assembly, the inner peripheral wall of the drum 200 has a circular profile. In order to fit closely against the inner peripheral wall of the drum 200, the second sidewall has an arc-shaped profile.

[0044] Optionally, the wind deflector 300 is fixed to the air valve 100 by threaded fasteners.

[0045] For example, the wind deflector 300 has a first connecting hole, and the air valve 100 has a second connecting hole. The threaded fastener includes a screw portion and a nut portion, which are fixedly connected. The nut portion is located on the side of the wind deflector 300 facing away from the air valve 100. After passing through the first connecting hole, the screw portion is threadedly connected to the air valve 100 in the second connecting hole. As the screw portion is tightened, the wind deflector 300 is clamped between the nut portion and the air valve 100. This facilitates the assembly of the wind deflector 300 and the air valve 100.

[0046] Optionally, a guide strip 420 protrudes from the first end face of the rubbing board 400, and the length direction of the guide strip 420 is parallel to the axial direction of the drum 200. Since the guide strip 420 is higher than the first end face, i.e., the distance between the guide strip 420 and the surface of the drum 200 is smaller than the distance between the first end face and the surface of the drum 200, when the drum 200 carrying the cigarette assembly passes the guide strip 420, the tipping paper contacts the guide strip 420 and rolls, thus facilitating the twisting of the tipping paper. For example, a slot is provided on the first end face of the rubbing board 400, and the guide strip 420 is detachably installed in the slot.

[0047] For example, the washboard 400 and the guide strip 420 are integrally formed.

[0048] Optionally, multiple guide strips 420 can be provided, arranged in parallel. This arrangement allows for multiple compressions of the tipping paper, effectively improving the splicing quality of the cigarette assembly.

[0049] Optionally, a heating element is installed inside the rubbing board 400. When the heating element is activated, it can increase the temperature of the rubbing board 400. Thus, when the tipping paper comes into contact with the rubbing board 400, the latex on the tipping paper can quickly evaporate its moisture under high temperature baking, so that the latex is already dried and formed when the cigarette leaves the rubbing board 400.

[0050] Furthermore, multiple heating elements are provided, evenly distributed on the washboard 400.

[0051] Optionally, the anti-slip structure 410 is toothed. For example, the first end face of the washboard 400 has a toothed protrusion, the length direction of which is parallel to the axial direction of the drum 200 and continuous with the surface of the first end face of the washboard 400. It should be noted that the height of the toothed protrusion is less than the height of the guide strip 420.

[0052] Optionally, the air valve 100 has a mounting groove, and the wind deflector 300 is embedded in the mounting groove. For example, the air valve 100 has a mounting groove, and a first air port A110 and a first air port B120 are provided on the bottom wall of the mounting groove. The wind deflector 300 is installed in the mounting groove, and the second side wall of the wind deflector 300 is aligned with the opening end face of the mounting groove.

[0053] It should be noted that the surface contour of the air valve 100 is arc-shaped.

[0054] Optionally, the splicing assembly also includes an exhaust valve, which is installed on the air valve 100. The exhaust valve has a fourth air port, which can generate a positive pressure airflow. The positive pressure airflow is used to clear the second air port group 210.

[0055] For example, the exhaust valve is installed on the air valve 100 by a threaded fastener. The exhaust valve has a third connection hole, and the air valve 100 has a fourth connection hole. The fourth connection hole is a threaded hole. The threaded fastener includes a screw part and a nut part. The screw part is fixed to the nut part. After the screw part passes through the third connection hole, it is threadedly connected to the air valve 100 in the fourth connection hole. As the screw part is screwed, the exhaust valve is clamped between the nut part and the air valve 100.

[0056] It should be noted that the exhaust valve does not obstruct or interfere with the first air port A110 and the first air port B120 of the air valve 100.

[0057] During use, in the initial stage, the air valve 100 is closed, and the drum 200 begins to rotate around its axis, opening the exhaust valve. The fourth port of the exhaust valve provides positive pressure airflow, meaning the airflow blows from inside the drum 200 through the second port to the outside of the drum 200. This causes impurities adhering to the vicinity of the second port of the drum 200 to detach from the drum 200 under the action of the positive pressure airflow, keeping the second port unobstructed. Subsequently, the exhaust valve is closed, and the air valve 100 is opened, generating negative pressure airflow. That is, the airflow moves from the outside of the drum 200 through the second port to the inside of the drum 200, achieving adsorption of the cigarette assembly.

[0058] A cigarette rolling machine is also provided, including the aforementioned twisting assembly.

[0059] Furthermore, the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
