Description
Technical Field
[0001] This utility model relates to the technical field of cigarette machine tobacco feeding equipment, and in particular to a YJ118 metering trough tobacco feeding quantity adjustment device. Background Technology
[0002] The tobacco in the VE metering trough of the YJ118 cigarette making unit is monitored by 15 photoelectric switches. These switches are arranged in three groups of five, spaced apart along the width of the metering trough, continuously monitoring the tobacco level and controlling the speed of the conveyor belt. A cutting blade trims excess tobacco from the conveyor belt. The trimmed tobacco passes through a front spiral return device, a main spiral return device, and a rear spiral return device before returning to the pre-supply tobacco storage area.
[0003] The optimal state for the tobacco in the metering trough is a "U" shape, with the sides higher and the middle slightly lower. However, to ensure proper machine operation, this "U" shape is not always stable or continuous. In some cases, the tobacco may be higher in the middle and lower on both sides, or even higher on one side and lower on the other. This can lead to empty tobacco sticks, or even bamboo-like tobacco, and in severe cases, machine shutdown. In such situations, the adjusting plate of the equalizing roller must be adjusted. However, during adjustment, it was found that: firstly, the equalizing roller is hidden inside the spring roller, making adjustment extremely inconvenient and risking injury from the roller nails on the spring roller; secondly, the adjustment position of the adjusting plate on the equalizing roller is limited. Utility Model Content
[0004] The purpose of this invention is to provide a YJ118 metering trough tobacco feed adjustment device, which solves the problem in the prior art where the tobacco in the metering trough is U-shaped due to structural defects, making it difficult to form stability and continuity.
[0005] This utility model solves the above-mentioned technical problems through the following technical means: A YJ118 metering feeder tobacco feeder adjustment device is installed on a rear spiral feeder. The rear spiral feeder includes a spiral feeding mechanism and a semi-circular outer shell wrapped around the spiral feeding mechanism. The adjustment device includes an arc-shaped adjustment plate and a connecting assembly. The arc-shaped adjustment plate is located at the notch of the semi-circular outer shell. One side of the arc-shaped adjustment plate is movably connected to the bottom of the semi-circular outer shell, and the other side of the arc-shaped adjustment plate extends upward, so that the inner side of the arc-shaped adjustment plate faces the spiral feeding mechanism. One end of the connecting assembly is connected to the bottom of the semi-circular outer shell, and the other side is connected to the arc-shaped adjustment plate.
[0006] Through the above structural design, the connecting component supports the arc-shaped adjustment plate at the bottom of the semi-circular outer shell of the rear spiral feeding device. The arc-shaped adjustment plate is in a state of wrapping the spiral feeding mechanism. By setting the arc-shaped adjustment plate, when the rear spiral feeding device feeds the material, the original discharge path of some tobacco shreds and finer tobacco dust located at the bottom of the spiral feeding mechanism is changed. At the same time, the position of the arc-shaped adjustment plate is open, which greatly facilitates the adjustment of the continuity and stability of the tobacco shreds in the metering trough. It can well ensure that the tobacco shreds in the metering trough present a relatively perfect "U" shape.
[0007] Furthermore, the orthographic projection of the arc-shaped adjustment plate on the ground is a right trapezoid, the right-angled waist of the arc-shaped adjustment plate contacts the outer wall of the bottom of the semi-circular outer shell, and the width of the arc-shaped adjustment plate gradually decreases along the feeding direction of the spiral feeding mechanism.
[0008] Through the above structural design, the right-angled trapezoidal design of the arc-shaped adjustment plate facilitates the connection between the arc-shaped adjustment plate and the semi-circular outer shell. On the other hand, it makes the degree of obstruction of the tobacco shreds by the arc-shaped adjustment plate at different positions different, thereby affecting the accumulation pattern of the tobacco shreds in the metering trough. By adjusting the position and angle of the arc-shaped adjustment plate, the flow of tobacco shreds can be controlled more precisely, so that it forms a uniform "U"-shaped distribution in the metering trough.
[0009] Furthermore, the arc-shaped adjusting plate includes a first plate and a second plate. The first plate and the second plate are arranged sequentially along the feeding direction of the spiral feeding mechanism. The end of the first plate near the second plate overlaps the second plate. Both the first plate and the second plate are supported on the semi-circular outer shell by connecting components.
[0010] By adjusting the overlap length of the first and second adjustment plates through the above structural design, the overall length of the arc-shaped adjustment plate can be adjusted.
[0011] Furthermore, the connecting assembly includes a fixing plate, a connecting plate, and an arc-shaped mounting plate. The fixing plate is fixed to the bottom of the semi-circular outer shell, and the arc-shaped mounting plate is fitted onto the outer wall of the arc-shaped adjusting plate. A locking assembly is provided between the arc-shaped mounting plate and the arc-shaped adjusting plate. One end of the connecting plate is fixedly connected to the fixing plate, and the other end is fixedly connected to the arc-shaped mounting plate.
[0012] The above structural design facilitates the installation of the arc-shaped adjustment plate.
[0013] Furthermore, the connecting plate is L-shaped, and a fixing member is provided between the connecting plate and the fixing plate. The vertical section of the connecting plate is provided with a first elongated groove along the vertical direction for the fixing member to pass through and the fixing position of the fixing member is adjustable. One end of the fixing member passes through the first elongated groove and is fixedly connected to the fixing plate. The horizontal section of the connecting plate is fixedly connected to the arc-shaped mounting plate.
[0014] The above structural design allows for adjustment of the vertical height of the curved adjustment plate.
[0015] Furthermore, the locking assembly includes a bolt and a locking nut. The arc-shaped adjusting plate has a second elongated groove for the bolt to pass through and the bolt fixing position is adjustable. The second elongated groove extends along the width direction of the arc-shaped adjusting plate. The arc-shaped mounting plate has a through hole for the bolt to pass through. One end of the bolt passes through the second elongated groove and the through hole in sequence and cooperates with the locking nut.
[0016] Through the above structural design, the bolts and locking nuts can lock and fix the arc-shaped mounting plate and the arc-shaped adjusting plate. By adjusting the position of the bolts in the second long groove, the position of the inclined waist of the arc-shaped adjusting plate can be adjusted.
[0017] Furthermore, multiple elongated slots are provided at intervals along the length of the arc-shaped adjustment plate, and multiple connecting components are provided, each corresponding to one of the elongated slots.
[0018] The above structural design increases the installation stability of the arc-shaped adjustment plate.
[0019] The beneficial effects of this utility model are as follows:
[0020] This invention adds an arc-shaped adjustment plate to the rear spiral return device. The arc-shaped adjustment plate is easy to install and adjust. It can control the amount of tobacco at both ends of the storage area of the pre-supply tobacco body after the rear spiral return. The tobacco in the storage area of the pre-supply tobacco body is lifted by the lifting belt and finally reaches the metering trough. This greatly facilitates the adjustment of the continuity and stability of the tobacco in the metering trough and can well ensure that the tobacco in the metering trough presents a relatively perfect "U" shape.

[0031] In related technologies, the post-spiral tobacco return device includes a spiral feeding mechanism and a semi-circular outer shell surrounding the spiral feeding mechanism. The semi-circular outer shell is located behind the spiral feeding mechanism, and the notch of the semi-circular outer shell is located in front of the spiral feeding mechanism. When the tobacco is spirally fed by the spiral feeding mechanism, the tobacco falls outward from the bottom of the semi-circular outer shell through the notch and falls into the storage area of the pre-supply tobacco. After being lifted by the lifting belt, it finally reaches the metering trough. The structure of the post-spiral tobacco return device has been fully disclosed in the existing technology, and will not be elaborated further here. However, in the actual operation of the equipment, it has been found that the stability and continuity of the "U" shape of the tobacco in the metering trough are difficult to guarantee, especially for thin cigarettes (such as 5.4mm thin cigarettes). The distribution of tobacco storage in the metering trough is unstable, often with one side higher than the other or the middle higher than the two sides. This results in loose ends and unstable weight of the cigarette.
[0032] like Figure 1-6 As shown in the figure, this utility model embodiment proposes a YJ118 metering trough tobacco feed adjustment device, including an arc-shaped adjusting plate 4 and a connecting assembly. The arc-shaped adjusting plate 4 is located at the notch of the semi-circular outer shell 1. One side of the arc-shaped adjusting plate 4 is connected to the bottom of the semi-circular outer shell 1, and the other side of the arc-shaped adjusting plate 4 extends upward, so that the inner side of the arc-shaped adjusting plate 4 faces the spiral feeding mechanism 2. One end of the connecting assembly is connected to the bottom of the semi-circular outer shell 1, and the other side is connected to the middle of the arc-shaped adjusting plate 4. The orthographic projection of the arc-shaped adjusting plate 4 on the ground is a right trapezoid. The right-angled side of the arc-shaped adjusting plate 4 slides in contact with the outer wall of the bottom of the semi-circular outer shell 1. The width of the arc-shaped adjusting plate 4 gradually decreases along the feeding direction of the spiral feeding mechanism 2. In this embodiment, as shown in the figure... Figure 1As shown, the feeding direction of the rear spiral wire return device is from left to right. The left end of the arc-shaped adjusting plate 4 is aligned with the left end of the spiral feeding mechanism 2. A material feeding space is reserved between the right end of the arc-shaped adjusting plate 4 and the spiral feeding mechanism 2. The arc length and width of one side of the arc-shaped adjusting plate 4 at the right end is 130mm, and the arc length and width of the other side are 150mm. The length of the entire arc-shaped adjusting plate is 600mm. Multiple second long strip grooves 5 with a diameter of 8mm are processed at intervals along the length direction on the arc-shaped adjusting plate. The second long strip grooves 5 extend 65mm along the width direction of the arc-shaped adjusting plate 4. The spacing between two adjacent second long strip grooves 5 can be determined according to the actual situation. With this structural design, as the spiral feeding mechanism 2 conveys the tobacco shreds from left to right, the arc-shaped adjusting plate 4 alters the falling path of some tobacco shreds. After adding the arc-shaped adjusting plate 4, the falling tobacco shreds form a "U" shape at the left end of the arc-shaped adjusting plate 4, and a second "U" shape is formed in the material feeding space between the right end of the arc-shaped adjusting plate 4 and the spiral feeding mechanism 2. After being lifted by the lifting belt 3, the tobacco shreds finally reach the metering trough, which greatly facilitates the adjustment of the continuity and stability of the tobacco shreds in the metering trough and can well ensure that the tobacco shreds in the metering trough present a relatively perfect "U" shape.
[0033] The arc-shaped adjusting plate 4 includes a first plate 41 and a second plate 42, which are arranged sequentially along the feeding direction of the spiral feeding mechanism 2. The right end of the first plate 41 overlaps the left end of the second plate 42. Both the first plate 41 and the second plate 42 are supported on the semi-circular outer shell 1 by connecting components. In this embodiment, the first plate 41 and the second plate 42 are spliced together to form the arc-shaped adjusting plate 4. Both the first plate 41 and the second plate 42 are provided with a second elongated groove 5. This structural design allows for the preparation of multiple second plates 42 in advance. The distance between the second elongated groove 5 on each second plate 42 and the left end face of the second plate 42 is different. By using different second plates 42, the overall length of the arc-shaped adjusting plate 4 can be adjusted to adapt to various situations in the actual production process, making it highly adaptable.
[0034] The connecting assembly includes a fixing plate 6, a connecting plate 7, and an arc-shaped mounting plate 9. The fixing plate 6 is vertically welded to the bottom of the semi-circular outer shell 1. The arc-shaped mounting plate 9 is fitted against the outer wall of the arc-shaped adjusting plate 4. A locking assembly is provided between the arc-shaped mounting plate 9 and the arc-shaped adjusting plate 4. One end of the connecting plate 7 is fixedly connected to the fixing plate 6, and the other end is fixedly connected to the arc-shaped mounting plate 9. In this embodiment, the arc-shaped mounting plate 9 provides support for the arc-shaped adjusting plate 4 and seals the second elongated groove 5, preventing tobacco from falling down into the second elongated groove 5 and affecting the metering effect of tobacco in the metering groove.
[0035] The connecting plate 7 is L-shaped, and a fixing member 8 is provided between the connecting plate 7 and the fixing plate 6. A first elongated groove 12 is provided along the vertical direction on the vertical section of the connecting plate 7 for the fixing member 8 to pass through, and the fixing member 8's fixed position is adjustable. One end of the fixing member 8 passes through the first elongated groove 12 and is fixedly connected to the fixing plate 6. The horizontal section of the connecting plate 7 is fixedly connected to the arc-shaped mounting plate 9. In this embodiment, the fixing member 8 includes a screw and a fixing nut. One end of the screw is welded to the fixing plate 6, and the other end passes through the first elongated groove and cooperates with the fixing nut to lock and fix the connecting plate 7 and the fixing plate 6. By loosening the fixing nut to adjust the vertical height of the connecting plate 7, and then tightening the fixing nut, the vertical height of the arc-shaped adjusting plate 4 can be adjusted. The structure is simple and the adjustment is convenient.
[0036] The locking assembly includes a bolt 10 and a locking nut 11. A through hole is provided on the arc-shaped mounting plate 9 for the bolt 10 to pass through. One end of the bolt 10 passes sequentially through the second elongated groove 5 and the through hole, and engages with the locking nut 11 to lock and fix the arc-shaped mounting plate 9 and the arc-shaped adjusting plate 4. By loosening the locking nut 11, the position of the inclined section of the arc-shaped adjusting plate 4 can be adjusted, and then the locking nut 11 can be tightened again, making the discharge height of the arc-shaped adjusting plate 4 adjustable.
[0037] Multiple second elongated slots 5 are spaced apart along the length of the arc-shaped adjusting plate 4, and multiple connecting components are provided, each corresponding to one of the second elongated slots 5. In this embodiment, according to actual conditions, at least one second elongated slot 5 is provided on both the first plate 41 and the second plate 42 to increase the installation stability of the arc-shaped adjusting plate 4.
[0038] Working principle:
[0039] The tobacco shreds are conveyed from left to right by the spiral feeding mechanism 2. A portion of the tobacco shreds accumulates at the left end of the arc-shaped adjusting plate 4 and falls outwards. Simultaneously, driven by the tobacco shreds subsequently conveyed by the feeding mechanism, the tobacco shreds at the left end of the arc-shaped adjusting plate 4 fall into the pre-supply tobacco storage area, forming a "U" shape. A second "U" shape is formed in the unloading space between the right end of the arc-shaped adjusting plate 4 and the spiral feeding mechanism 2. After being lifted by the lifting belt 3, the tobacco finally reaches the metering trough. This greatly facilitates the adjustment of the continuity and stability of the tobacco shreds in the metering trough, ensuring a near-perfect "U" shape. The added arc-shaped adjusting plate 4 is also easy to adjust, significantly reducing maintenance time and improving maintenance efficiency. Although the improvement is simple, the effect is significant, effectively increasing the equipment's effective operating rate and ensuring product quality.
