Description

Technical Field

[0001] This application relates to the field of cigarette equipment technology, and specifically to an isolation device for the firing unit of a filter rod emitter. Background Technology

[0002] Filter rods are one of the important raw materials in cigarette production, and they have the function of reducing tar and harm. After being produced by the filter rod forming machine, the filter rods are pneumatically conveyed to the cigarette rolling equipment by the filter rod dispenser.

[0003] Filter rod dispensers typically have multiple horizontally arranged dispensing units, each of which can operate independently. During operation, filter rods enter each dispensing unit from the feed hopper and are adsorbed into the grooves of the dispensing drum under the negative pressure. The rotation of the dispensing drum transports the filter rods to the dispensing pipe, where they are then conveyed by high-pressure air to the subsequent cigarette rolling equipment.

[0004] During production, the filter rod emitter usually only uses some of the emitter units, with the idle emitter units serving as backups. When an emitter unit malfunctions, it is promptly replaced by an idle emitter unit, thus ensuring a continuous supply of filter rods.

[0005] Currently, the only solution for idle emitter units is to stop the corresponding emitter drum, without further processing. This results in a large number of filter rods accumulating inside the idle emitter units. As the idle time increases, dust in the air and lint adhering to the filter rods gradually accumulate at the idle emitter units. Since the filter rods have a porous structure, they easily attract impurities, ultimately leading to contamination and filter rod wear. Furthermore, because contaminated filter rods are unusable, they must be cleaned before activating the idle emitter units, which is time-consuming, labor-intensive, and impacts production efficiency. Utility Model Content

[0006] This application provides an isolation device for the transmitting unit of a filter rod transmitter, which aims to solve the problem of filter rod retention at idle transmitting units.

[0007] To achieve the above objectives, this application employs the following technical solution:

[0008] An isolation device for the launching unit of a filter rod launcher includes a material hopper, launching drums, and partitions. Several launching drums are evenly installed at the bottom of the material hopper, and adjacent launching drums are separated by partitions to form several launching units. The device also includes:

[0009] A baffle is detachably installed on the top of the transmitting unit to block the filter rod. The baffle has a slot on one side and a corresponding block on the other side, so that adjacent baffles can be connected as one unit. The bottom of the baffle is also provided with a support foot for the corresponding partition.

[0010] A locking component is installed at the support leg, and the partition plate is provided with an arc-shaped groove corresponding to the locking component, so that the position of the baffle can be fixed by the locking component;

[0011] Adjusting plates are vertically slidably installed on the left and right sides of the material hopper. By sliding the adjusting plates, the integrated baffle can be lifted to form an inclined surface, which facilitates the rolling of the filter rods.

[0012] The material storage silo has a disassembly port on its side, and a movable plate that can be opened and closed is installed at the disassembly port. The baffle can be disassembled and assembled from the movable port.

[0013] Optionally, in some embodiments, the top of the baffle is a planar structure.

[0014] Optionally, in some embodiments, the baffle has a groove at its support foot, a mounting hole is provided in the groove, and a locking component is installed at the mounting hole.

[0015] Optionally, in some embodiments, the locking assembly includes a spring, a slider, a connecting rod, and an arc-shaped block. The slider is slidably connected in the mounting hole, one end of the slider is fixed to the arc-shaped block through the connecting rod, and the other end is provided with a spring, which is always in a compressed state.

[0016] Optionally, in some embodiments, the arcuate block and the arcuate groove have the same curvature, and the width of the arcuate block is greater than the width of the arcuate groove.

[0017] Optionally, in some embodiments, the top of the adjustment plate is provided with a support protrusion.

[0018] Optionally, in some embodiments, the left and right sides of the material storage are provided with vertical chutes, and the adjusting plate is fixedly connected to a slider, and the adjusting plate is slidably connected to the chutes through the slider.

[0019] Optionally, in some embodiments, the slider has a fixing hole, and the material magazine has a first positioning hole and a second positioning hole respectively along the vertical direction. By aligning the fixing hole with the first positioning hole or the second positioning hole and inserting the plug rod to fix the slider, the height of the adjusting plate can be adjusted.

[0020] Optionally, in some embodiments, the top of the movable plate is mounted at the disassembly port via a hinge, and an iron sheet is fixedly connected to its bottom. A magnet corresponding to the iron sheet is fixedly connected to the side of the material storage.

[0021] Optionally, in some embodiments, a handle is fixedly attached to the movable plate.

[0022] The beneficial effects of this application are:

[0023] This application utilizes a baffle installed at the idle emission unit to block the filter rods. This prevents the filter rods from becoming stuck inside the idle emission unit and also prevents dust, lint, and other impurities from entering, ensuring the cleanliness of the space within the idle emission unit. When needed, the baffle can be easily and quickly removed. Furthermore, by using a sliding adjustment plate, the integrated baffle can be raised to form an inclined surface, increasing the flowability of the filter rods and preventing them from becoming stuck in the material hopper for extended periods due to dead zones.

[0043] This application proposes improvements and innovations, and presents the following embodiments.

[0044] See Figure 1 , Figure 2An isolation device for the launching unit of a filter rod launcher includes a material storage chamber 1, launching drums 2, and partitions 5. The material storage chamber 1 is a hollow square structure, usually made of transparent acrylic sheet, used for temporary storage of filter rods to ensure stable material supply. A filter rod launcher (not shown in the figure) is connected to the bottom of the material storage chamber 1. The launching drums 2 of the filter rod launcher are evenly arranged at the bottom of the material storage chamber 1, and adjacent launching drums 2 are separated by partitions 5, thus forming several launching units. The number of launching units is equal to the number of launching drums 2. In this embodiment, nine launching units are provided. Furthermore, each launching drum 2 has several grooves evenly arranged along its circumference. The bottom of the grooves is provided with negative pressure suction holes. In use, a negative pressure device is used to draw suction from the negative pressure suction holes, creating negative pressure at the grooves, thereby adsorbing and fixing the filter rods. As the launching drums 2 rotate, they drive the filter rods to rotate, thereby conveying the filter rods to the launching pipe, and then conveying the filter rods to the subsequent cigarette rolling equipment by high-pressure air. The filter rod emitter and its emitter drum 2 are existing technologies, and their structure and control methods will not be described in detail here.

[0045] An isolation device for a filter rod transmitter firing unit further includes:

[0046] Baffle 4, see Figure 3 , Figure 4 The baffle 4 is a square plate, usually made of acrylic sheet, with a flat top to facilitate subsequent flow guidance of the filter rods. One side of the baffle 4 has a trapezoidal slot 41, and the other side has a corresponding trapezoidal block 42. The slot 41 and block 42 are sized to match each other, allowing adjacent baffles 4 to be connected as a single, larger plate. The top of the partition 5 is usually pointed, forming supporting slopes 51 on its left and right sides. This facilitates both flow guidance of the filter rods and support of the baffle 4. Support legs 43 corresponding to the supporting slopes 51 are provided at the bottom of the baffle 4. In use, the baffle 4 is inserted into the material magazine 1 through the disassembly port 11 and placed on top of the emission unit to be sealed, ensuring that the support legs 43 on both sides of the baffle 4 are in contact with the supporting slopes 51 on the same side, thus completing the installation.

[0047] Activity board 3, see Figure 1 To facilitate the disassembly and assembly of the baffle 4, a disassembly and assembly port 11 corresponding to the top of the launching unit is provided on the side of the material storage 1. A movable plate 3 that can be opened and closed is installed at the disassembly and assembly port 11. When it is necessary to disassemble or assemble the baffle 4, the movable plate 3 is opened for easy operation. After disassembly or assembly, the movable plate 3 is closed to prevent the filter rod from leaking out from the disassembly and assembly port 11. Specifically, the movable plate 3 is a long strip of acrylic plate, and its top is installed at the disassembly and assembly port 11 by a hinge 31, so that the movable plate 3 can rotate around the hinge 31. An iron plate 33 is fixedly connected to the bottom of the movable plate 3, and a magnet 34 corresponding to the iron plate 33 is fixedly connected to the side of the material storage 1. A handle 32 is also fixedly connected to the movable plate 3.

[0048] Under normal conditions, the movable plate 3 hangs down under gravity, at which point the iron sheet 33 contacts the magnet 34, and the disassembly port 11 is closed. When the baffle 4 needs to be disassembled, the worker pulls the handle 32 outward to disengage the iron sheet 33 from the magnet 34 and causes the movable plate 3 to rotate around the hinge 31, thereby opening the disassembly port 11. Furthermore, since the length of the disassembly port 11 is equal to the sum of the widths of all the transmitting units, the length of the disassembly port 11 is usually quite long, generally over 1 meter. An excessively long movable plate 3 would affect the ease of opening and closing. Therefore, the movable plate 3 can be divided into multiple segments, each segment of the movable plate 3 installed in the same way as described above, allowing each segment of the movable plate 3 to be opened and closed independently, improving the ease of opening and closing the movable plate 3. In this embodiment, the movable plate 3 is divided into left and right segments.

[0049] Adjustment plate 8, see Figure 1 The adjusting plates 8 are vertically slidable on the left and right sides of the hopper 1. By sliding the adjusting plates 8, the integrated baffle 4 can be lifted, forming an inclined surface to facilitate the guidance of the filter rods to the launching unit in operation. The baffle 4 can be installed in various ways, such as spaced installation or continuous installation. Multiple continuously installed baffles 4 can be located on one side of the hopper 1 or in the middle of the hopper 1. See also... Figure 2 When more than four baffles 4 are installed consecutively and located on one side of the material hopper 1, the filter rods near the edge of the material hopper 1 may not be able to flow, forming a "dead zone". If the filter rods remain in the dead zone for a long time, with the accumulation of dust and other impurities in the material hopper, coupled with the porous nature of the filter rods, the filter rods are easily contaminated, affecting normal use.

[0050] See Figure 9 , Figure 10 When a dead zone is present, the baffle 4, which is integrated with the filter rod, is lifted by the adjusting plate 8 to form an inclined surface, thereby increasing the flowability of the filter rod and preventing the formation of a dead zone. Specifically, the left and right sides of the material hopper 1 are provided with vertically arranged grooves 12. A slider 62 is fixedly connected to the adjusting plate 8, and the adjusting plate 8 is slidably connected to the groove 12 through the slider 62, so that the adjusting plate 8 can slide vertically. A support protrusion 81 for lifting the baffle 4 is also provided on the top of the adjusting plate 8. Furthermore, the slider 62 has a fixing hole 83, and the material hopper 1 has a first positioning hole 13 and a second positioning hole 14 respectively along the vertical direction. The number of positioning holes can be increased according to needs.

[0051] Under normal conditions, the fixing hole 83 is aligned with the first positioning hole 13, and the insert rod 84 penetrates the fixing hole 83 and is inserted into the first positioning hole 13 to fix the position of the slider 62. At this time, the adjusting plate 8 is flush with the partition plate 5. When there is a risk of dead zone, the insert rod 84 is pulled out, the slider 62 is moved up, so that the fixing hole 83 is aligned with the second positioning hole 14. The baffle 4 connected as a whole is lifted by the adjusting plate 8 to form an inclined surface. Then the slider 62 is re-fixed by the insert rod 84 to complete the adjustment.

[0052] The aforementioned baffle 4 is installed entirely by gravity. During use, due to factors such as equipment vibration, collision, or installation errors, the baffle 4 is prone to tilting, causing it to slip into the transmitting unit and lose its effect of blocking the filter rod. Therefore, locking components 6 are also installed at the support feet 43 on both sides of the baffle 4 to fix its position.

[0053] In some embodiments, see Figure 5 , Figure 6 , Figure 7 Grooves 44 are provided at the support feet 43 on both sides of the baffle 4. A mounting hole 45 is provided in the middle of the groove 44. The mounting hole 45 has a two-section structure, namely a limiting section and a mounting section. The section farther away from the groove 44 is the mounting section, which has a larger diameter and is used to install the locking component 6. The section closer to the groove 44 is the limiting section, which has a smaller diameter and is used to limit the stroke of the locking component 6. An arc-shaped groove 52 corresponding to the locking component 6 is provided in the middle of the support slope 51. The locking component 6 is engaged with the arc-shaped groove 52 to fix the position of the baffle 4. Specifically, the locking component 6 includes a spring 61, a slider 62, a connecting rod 63, and an arc-shaped block 64. The slider 62 is slidably connected within the mounting section of the mounting hole 45. One end of the slider 62 is fixedly connected to the connecting rod 63, which passes through the limiting section of the mounting hole 45 and is then fixedly connected to the arc-shaped block 64. The other end of the slider 62 is connected to the spring 61, which is located within the mounting section of the mounting hole 45 and is always in a compressed state. At this time, the slider 62 reaches its maximum stroke under the action of elastic force, causing the arc-shaped block 64 to extend out of the groove 44, facilitating engagement with the arc-shaped groove 52.

[0054] Further, see Figure 6 , Figure 8 The arc of the arc-shaped block 64 and the arc-shaped groove 52 are consistent, allowing the arc-shaped block 64 to fit better into the arc-shaped groove 52 when snapped in, ensuring the stability of the snap-in. The lateral width X1 of the arc-shaped groove 52 is smaller than the lateral width X2 of the arc-shaped block 64, so that when the arc-shaped block 64 is snapped in the arc-shaped groove 52, its left and right ends extend beyond the arc-shaped groove 52, facilitating subsequent disassembly.

[0055] During installation, the worker inserts the baffle 4 into the hopper 1 through the disassembly port 11, and makes the support feet 43 on both sides of the baffle 4 fit against the supporting inclined surface 51. During the insertion of the baffle 4, the arc-shaped block 64 is squeezed inward by the supporting inclined surface 51, which drives the slider 62 to slide and press the spring 61. As the baffle 4 is fully inserted into the hopper 1, the arc-shaped block 64 moves to the arc-shaped groove 52. Under the action of the elastic force, the arc-shaped block 64 is pushed up and stuck into the arc-shaped groove 52, thus completing the snap-fit ​​fixation. At this time, under the fixing action of the arc-shaped block 64, the baffle 4 can no longer tilt, thereby improving the stability of the baffle 4.

[0056] After the baffle 4 is fixed in the arc groove 52 by the locking component 6, it can be directly disassembled by pulling. The specific process is as follows: the worker puts his hand into the material hopper 1 from the disassembly port 11 and holds the edge of the baffle and pulls it outward. Since the left and right sides of the arc groove 52 are smooth arcs, when the baffle 4 is subjected to lateral force, the arc block 64 will be gradually squeezed back into the groove 44, releasing the positioning effect. By continuing to pull the baffle 4, it can be taken out of the material hopper 1 from the disassembly port 11.

[0057] However, although the above method can directly disassemble the baffle 4, the space at the disassembly port 11 is narrow, and pulling the baffle 4 can easily result in excessive force and finger injury. Therefore, in some embodiments, a special tool for assisting in disassembling the baffle 4 is provided, see [link to relevant documentation]. Figure 6 , Figure 7 The tool is a disassembly rod 7, which has a square structure and its dimensions match the groove 44. A pressure plate 71 is provided at the end of the disassembly rod 7. The pressure plate 71 is made of a rigid material to facilitate the compression of the arc-shaped block 64. The specific usage is as follows: the disassembly rod 7 is inserted into the groove 44 from the side, and the pressure plate 71 is positioned on one side of the supporting inclined surface 51. Since the arc-shaped block 64 is wider than the arc-shaped groove 52, when the arc-shaped block 64 is engaged in the arc-shaped groove 52, a gap will be formed between the end of the arc-shaped block 64 and the supporting inclined surface 51. As the disassembly rod 7 extends, the pressure plate 71 is inserted from the gap and compresses the arc-shaped block 64, causing the arc-shaped block 64 to retract into the groove 44. After the two disassembly rods 7 compress and retract the arc-shaped blocks 64 on both sides of the baffle 4, the worker can then remove the baffle 4 from the material storage 1. This method eliminates the need for manual pulling of the baffle 4, improving the safety of the disassembly process.

[0058] The above are merely optional embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this utility model. Those skilled in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of this utility model.
