Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tobacco machinery technology, specifically relating to a cigarette blocking mechanism. Background Technology
[0002] As the tobacco industry increases its investment in product research and development and innovation, focusing on the development of healthy and low-harm tobacco products, cigarette filters are evolving from single-function to multi-function. Filters with added particulate matter are increasingly used in the production of new cigarette products. Many brands of cigarettes, due to the presence of particulate matter in their filters, require pre-separation of the filter and cigarette during cigarette recycling. When existing cigarette and filter separators stop operating, cigarettes continue to enter the inlet drum due to inertia. During shutdown, color difference detection is not activated, and cigarettes do not automatically align, leading to inaccurate cutting of the cigarette and filter, and the mixing of particulate matter into the unfiltered cigarettes, increasing the difficulty of recycling the tobacco. Therefore, a cigarette blocking mechanism needs to be designed to prevent cigarettes from entering the inlet drum when the cigarette and filter separator stops, ensuring accurate separation of the cigarette and filter, improving the purity of the recycled tobacco, protecting product and consumer health, and promoting high-quality development of the industry.

[0041] The present invention provides a cigarette blocking mechanism that blocks the cigarette from entering the inlet drum 4 when the cigarette and filter separator is stopped, ensuring the accuracy of the separation of the cigarette without a filter and the filter, and preventing filter rod particles from mixing into the cigarette without a filter, thereby improving the purity of the recycled tobacco.
[0042] like Figure 1-7 The cigarette blocking mechanism of this application includes: a compressed air source, a compressed air control unit, and a cigarette blocking unit.
[0043] The compressed air control unit is used to control the on / off state and magnitude of compressed air in this mechanism, thereby controlling the working time of the cigarette blocking unit and providing power for its operation. The cigarette blocking unit is a mechanical structure that blocks cigarettes, and the blocking and release of cigarettes are achieved by raising and lowering the cigarette partition 11.
[0044] The compressed air control unit includes a solenoid valve 1, a throttle valve 2, and a connecting air pipe 13. The solenoid valve 1 controls the supply of compressed air. Upon receiving a stop signal, the solenoid valve 1 supplies air to the mechanism and stops supplying air after the machine has completely stopped.
[0045] The throttle valve 2 is used to adjust the gas supply pressure, thereby controlling the height at which the cigarette holder partition 11 is raised.
[0046] The cigarette blocking unit consists of a cigarette partition 11, a partition guide rail 5, and a partition lifting assembly.
[0047] The cigarette baffle 11 is arc-shaped, and its curvature and width are the same as the curvature and width of the middle groove of the inlet drum 4. Its length is the length from the bottom of the baffle guide rail 5 to the cigarette blocking roller 3.
[0048] The partition guide rail 5 is used to fix the cigarette holder partition 11 and the partition lifting assembly. The upper part of the partition guide rail 5 has a movable groove 5-1 for the cigarette holder partition. The lower part of the partition guide rail 5 has a cylindrical groove for installing the partition lifting assembly.
[0049] The width of the movable groove 5-1 of the partition rail 5 is the same as the width of the cigarette partition 11. It is used to position the partition 11 during its lifting and lowering process to prevent the cigarette partition 11 from tilting under the uneven gravity of the cigarettes. After the cigarette is blocked by the partition 11, it will move along the partition 11. A cigarette collecting device can be installed downstream of the partition 11.
[0050] like Figure 3 and 7 The partition lifting assembly is installed in the cylindrical groove at the bottom of the partition guide rail 5. It includes a pin 6, a spring 7, and a sealing ring 8, and has a piston-like structure. The spring 7 is sleeved on the column of the pin 6, with one end of the spring 7 abutting against the cap of the pin 6 and the other end abutting against the pin head. The pin head is a retaining ring 12. The end of the column of the pin 6 passes through the pin head.
[0051] The cap of the ejector pin 6 is restricted to move within a certain range within the cylindrical groove. A sealing ring 8 covers the outer edge of the cap of the ejector pin 6 to provide a seal. The other end of the cylindrical groove is connected to the air pipe 13 via a connecting tube head 12.
[0052] When air is supplied, compressed air pushes the cap of the ejector pin 6 to move, pushing the ejector pin 6 out and acting on the cigarette holder 11, so that the cigarette holder 11 is pressed down into the middle groove of the inlet drum 4. When the cigarette blocking mechanism is not supplied with air, the spring 7 resets the ejector pin 8, so that the cigarette holder 11 moves upward away from the middle groove of the inlet drum 4.
[0053] Under air pressure, the ejector pin 6 extends to the bottom of the cigarette holder 11, positioning it within the central groove of the inlet drum 4, at which point the spring 7 is compressed. When compressed air is not supplied, the spring 7 automatically rebounds, causing the ejector pin 6 to retract, and the cigarette holder 11 automatically resets under its own weight. The sealing ring 8 ensures a tight airtight seal between the cap of the ejector pin 6 and the cylindrical groove wall, guaranteeing accurate stroke of the ejector pin 6. The movable block 9 and the stop block 10 fix and limit the movement of the cigarette holder 11.
[0054] The curvature and width of the cigarette baffle 11 are the same as the curvature and width of the middle groove of the inlet drum 3, and the length is the length from the bottom of the baffle guide rail 5 to the cigarette blocking roller 3.
[0055] like Figure 6 The cigarette holder 11 is fixedly connected to a movable block 9 with a through hole. A connecting post 14 passes through the through hole of the movable block 9 and is fixedly connected to the holder guide rail 5, so that the connecting post 14 and the movable block 9 are rotatably connected, thereby enabling the cigarette holder 11 to be rotatably connected to the holder guide rail 5. The movable block 9 can also be called a sliding sleeve. The connecting post 14 is called a pin.
[0056] The working principle of this application is as follows:
[0057] In the initial state, the cigarette divider 11 is held in a second position where it cannot block the cigarette due to its own shape and gravity.
[0058] When the cigarette and filter separator stops, solenoid valve 1 is energized, the valve is closed, and compressed air pushes the cap of ejector pin 6 to move. Under the action of air pressure, ejector pin 6 pushes out and acts on cigarette baffle 11. Cigarette baffle 11 is pressed down into the middle groove of the inlet drum 4, reaching the first position that can block the cigarette. At this time, the cigarette cannot enter the inlet drum 4. Figure 5 As shown, spring 7 is compressed.
[0059] When the cigarette and filter separator completely stops, solenoid valve 1 is de-energized, the valve closes, spring 7 rebounds, and under the action of spring 7, pin 6 retracts completely, and cigarette partition 11 resets. Figure 4 As shown.
[0060] The cigarette blocking mechanism provided by this utility model is simple in design and stable in operation. It can effectively block the cigarette from entering the inlet drum when the cigarette and filter separator stops, ensuring the accuracy of cigarette and filter separation and improving the purity of the recycled tobacco.
