Description

Technical Field

[0001] The present application relates to the technical field of cigarette making equipment, and in particular to an isolation device for a launching unit of a filter rod launcher. Background Art

[0002] Filter rods are a key raw material in cigarette production, known for their ability to reduce tar and harm. After being produced by a filter rod forming machine, they are pneumatically transported to the cigarette joining equipment via a filter rod ejector.

[0003] The filter rod ejector typically features multiple horizontally arranged ejection units, each capable of independent operation. During operation, filter rods enter each ejection unit from the material storage and are attracted to the grooves of the ejection drum under the negative pressure. The rotation of the ejection drum transports the filter rods to the ejection pipe, where they are then transported by high-pressure air to the subsequent cigarette-joining equipment.

[0004] During production, the filter rod launcher usually only uses part of the launch units, and the idle launch units are used as backup. When a launch unit fails, the idle launch unit is promptly replaced to ensure the continuous supply of filter rods.

[0005] Currently, the only treatment for idle launch units is to stop the launch drum at the corresponding position without further processing, resulting in a large number of filter rods being retained in the idle launch units. As the idle time increases, dust in the air and filaments attached to the filter rods gradually accumulate in the idle launch units. In addition, the filter rods have a porous structure and are prone to adsorbing impurities, which ultimately leads to contamination of the filter rods in the idle launch units, resulting in filter rod loss. Furthermore, since contaminated filter rods cannot be used, the contaminated filter rods need to be removed before the idle launch unit is activated, which is time-consuming and labor-intensive, affecting production efficiency. Summary of the Invention

[0006] The present application provides an isolation device for a launch unit of a filter rod launcher, aiming to solve the problem of filter rods being retained at an idle launch unit.

[0007] To achieve the above objectives, this application is implemented through the following technical solutions:

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

[0009] The baffle is detachably mounted on the top of the emission unit to block the filter rod. A slot is provided on one side of the baffle, and a corresponding block is provided on the other side, so that adjacent baffles can be connected as one.

[0022] Beneficial effects of this application:

[0023] The present invention installs a baffle at the idle launch unit to block the filter rod.

When it is needed, the baffle can be directly pulled out, which is convenient and quick. In addition, by sliding the adjustment plate, the integrated baffle can be lifted to form an inclined surface, increasing the fluidity of the filter rod and preventing the filter rod from being retained in the material storage for a long time due to dead zones.

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

[0044] See also Figure 1 、 Figure 2An isolation device for a filter rod launcher unit includes a material storage 1, a launch drum 2, and a partition 5. The material storage 1 is a hollow square structure, usually made of transparent acrylic board, and is used to temporarily store filter rods to ensure the stability of the feed. A filter rod launcher (not shown in the figure) is connected to the bottom of the material storage 1. The launch drums 2 of the filter rod launcher are evenly arranged at the bottom of the material storage 1, and adjacent launch drums 2 are separated by partitions 5, thereby forming a plurality of launch units. The number of launch units is equal to the number of launch drums 2. In this embodiment, nine launch units are provided. Furthermore, each launch drum 2 is evenly provided with a plurality of grooves along its circumference, and a negative pressure suction hole is provided at the bottom of the groove. When in use, the negative pressure suction hole is sucked by the negative pressure device, so that negative pressure is generated in the groove, thereby adsorbing and fixing the filter rod. As the launch drum 2 rotates, the filter rod is driven to rotate, thereby transporting the filter rod to the launch pipe, and then the filter rod is transported to the subsequent cigarette rolling equipment by high-pressure air. The filter rod launcher and its launching drum 2 are both prior art, and their structures and control methods are not described in detail here.

[0045] An isolation device for a filter rod launcher launch unit, further comprising:

[0046] Baffle 4, see Figure 3 、 Figure 4 The baffle 4 is a square plate, usually made of acrylic plate, with a flat top structure to facilitate the subsequent drainage of the filter rod. A trapezoidal slot 41 is provided on one side of the baffle 4, and a trapezoidal block 42 is provided on the other side. The sizes of the slot 41 and the block 42 match each other, so that adjacent baffles 4 can be connected as a whole to form a larger whole plate; the top of the partition 5 is usually pointed, so that support slopes 51 are formed on its left and right sides, which facilitate the diversion of the filter rod and the support of the baffle 4. Support legs 43 corresponding to the support slopes 51 are provided at the bottom of the baffle 4. When in use, the baffle 4 is inserted into the material storage 1 through the disassembly and assembly port 11 and placed on the top of the emission unit to be closed, so that the support legs 43 on the left and right sides of the baffle 4 fit into the support slopes 51 on the same side, thereby completing the installation.

[0047] Activity board 3, see Figure 1 To facilitate the removal and assembly of the baffle 4, a disassembly opening 11 corresponding to the top of the emission 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 opening 11. When the baffle 4 needs to be removed and assembled, the movable plate 3 is opened for easy operation. After the disassembly and assembly is completed, the movable plate 3 is closed to prevent the filter rod from leaking out of the disassembly opening 11. Specifically, the movable plate 3 is a long acrylic plate, the top of which is mounted on the disassembly opening 11 via a hinge 31, allowing the movable plate 3 to rotate around the hinge 31. An iron sheet 33 is fixed to the bottom of the movable plate 3, and a magnet 34 corresponding to the iron sheet 33 is fixed to the side of the material storage 1. A handle 32 is also fixed to the movable plate 3.

[0048] Under normal conditions, the movable panel 3 droops under the action of gravity, at which point the iron sheet 33 contacts the magnet 34, closing the assembly and disassembly opening 11. 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 flip the movable panel 3 around the hinge 31, thereby opening the assembly and disassembly opening 11. Furthermore, since the length of the assembly and disassembly opening 11 is equal to the sum of the widths of all the launch units, the length of the assembly and disassembly opening 11 is typically long, generally exceeding 1 meter. Excessive length of the movable panel 3 can affect the ease of opening and closing. Therefore, the movable panel 3 can be divided into multiple equal sections, each section of which is installed in the same manner as described above. This allows each section of the movable panel 3 to be opened and closed independently, improving the ease of opening and closing the movable panel 3. In this embodiment, the movable panel 3 is divided into two equal sections, the left and the right.

[0049] Adjustment plate 8, see Figure 1 The adjustment plate 8 is installed on the left and right sides of the material storage 1 along the vertical sliding direction. By sliding the adjustment plate 8, the baffle 4 connected to the material storage 1 can be lifted up to form an inclined surface, which is convenient for guiding the filter rod to roll to the launch unit in the running state. The baffle 4 can be installed in various ways, for example, it can be installed at intervals or continuously. Multiple baffles 4 installed continuously can be located on one side of the material storage 1 or in the middle of the material storage 1. Figure 2 When the number of baffles 4 installed continuously is more than four and located on one side of the material bin 1, it is easy to cause the filter rod near the edge of the material bin 1 to be unable to flow, forming a "dead zone". If the filter rod stays in the dead zone for a long time, with the deposition of dust and other impurities in the material bin, coupled with the porous characteristics of the filter rod, the filter rod is easily contaminated, affecting normal use.

[0050] See also Figure 9 、 Figure 10 When there is a risk of a dead zone, the integrated baffle 4 is lifted up through the adjustment plate 8 to form an inclined surface, thereby increasing the fluidity of the filter rod and avoiding the formation of a dead zone. Specifically, chutes 12 are vertically provided on both the left and right sides of the material storage 1, a slider 62 is fixedly connected to the adjustment plate 8, and the adjustment plate 8 is slidably connected to the chute 12 through the slider 62, so that the adjustment plate 8 can slide vertically, and a support protrusion 81 for lifting the baffle 4 is also provided on the top of the adjustment plate 8. Furthermore, a fixing hole 83 is provided on the slider 62, and a first positioning hole 13 and a second positioning hole 14 are respectively vertically provided on the material storage 1, and the number of positioning holes can be increased according to demand.

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

[0052] The aforementioned installation method of the baffle 4 relies entirely on gravity to secure the baffle 4. During use, due to factors such as vibration, collision, or installation errors, the baffle 4 can easily become skewed, causing the baffle 4 to slide into the emission unit and lose its ability to block the filter rods. Therefore, locking assemblies 6 are installed on the left and right legs 43 of the baffle 4 to secure the baffle 4 in place.

[0053] In some embodiments, see Figure 5 、 Figure 6 、 Figure 7 Grooves 44 are provided at the legs 43 on the left and right sides of the baffle 4, and a mounting hole 45 is provided in the middle of the groove 44. The mounting hole 45 is a two-section structure, namely a limiting section and a mounting section. The section away from the groove 44 is the mounting section, which has a larger aperture and is used to install the locking assembly 6; the section close to the groove 44 is the limiting section, which has a smaller aperture and is used to limit the stroke of the locking assembly 6. An arc-shaped groove 52 corresponding to the locking assembly 6 is provided in the middle position of the supporting inclined surface 51, and the locking assembly 6 is snap-connected to the arc-shaped groove 52, thereby fixing the position of the baffle 4. Specifically, locking assembly 6 includes a spring 61, a slider 62, a connecting rod 63, and an arc block 64. Slider 62 slides into the mounting section of mounting hole 45. One end of slider 62 is fixedly connected to connecting rod 63, which passes through the retaining section of mounting hole 45 and is fixedly connected to arc block 64. The other end of slider 62 is connected to spring 61, which is located in the mounting section of mounting hole 45 and is always in a compressed state. At this point, slider 62 reaches its maximum travel under the action of the elastic force, causing arc block 64 to extend out of groove 44, facilitating engagement with arc groove 52.

[0054] For further information, see Figure 6 、 Figure 8 The arc block 64 and the arc groove 52 have the same curvature, so that the arc block 64 can better fit the arc groove 52 when clamped, ensuring the stability of the clamping. Among them, the horizontal width X1 of the arc groove 52 is smaller than the horizontal width X2 of the arc block 64, so that when the arc block 64 is clamped in the arc groove 52, its left and right ends protrude from the arc groove 52, making it easier to disassemble later.

[0055] During installation, a worker inserts the baffle 4 into the material warehouse 1 from the disassembly and assembly port 11, and makes the support legs 43 on both sides of the baffle 4 fit into the supporting inclined surface 51. During the insertion of the baffle 4, the arc block 64 is squeezed inward by the supporting inclined surface 51, driving the slider 62 to slide and compress the spring 61; as the baffle 4 is fully inserted into the material warehouse 1, the arc block 64 moves to the arc groove 52, and the arc block 64 is lifted up and clamped into the arc groove 52 under the action of elastic force, thereby completing the clamping and fixing. At this time, under the fixing action of the arc block 64, the baffle 4 can no longer be skewed, thereby improving the stability of the baffle 4.

[0056] After the baffle 4 is fixed in the arc groove 52 by the locking assembly 6, the baffle 4 can be directly disassembled by pulling. The specific process is: the worker extends his hand into the material warehouse 1 from the disassembly and assembly port 11 and grasps 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 a lateral force, the arc block 64 will gradually be squeezed back into the groove 44, releasing the positioning effect. Continuing to pull the baffle 4 can remove it from the disassembly and assembly port 11 to remove it from the material warehouse 1.

[0057] However, although the above method can directly disassemble the baffle 4, due to the narrow space at the disassembly opening 11, it is easy to cause excessive force to cause fingers to be pinched when pulling the baffle 4. Therefore, in some embodiments, a tool specifically used to assist in disassembling the baffle 4 is provided. Figure 6 、 Figure 7 The tool is a dismantling rod 7. The dismantling rod 7 is square in structure and its size matches the groove 44. A pressure plate 71 is provided at the end of the dismantling rod 7. The pressure plate 71 is made of hard material, so as to facilitate the squeezing of the arc block 64. The specific method of use is as follows: the dismantling rod 7 is inserted into the groove 44 from the side, and the pressure plate 71 is located on the side of the supporting inclined surface 51. Since the arc block 64 is wider than the arc groove 52, when the arc block 64 is clamped in the arc groove 52, a gap is formed between the end of the arc block 64 and the supporting inclined surface 51. As the dismantling rod 7 is extended, the pressure plate 71 is inserted from the gap and squeezes the arc block 64, so that the arc block 64 shrinks into the groove 44. After the arc blocks 64 on both sides of the baffle 4 are squeezed and contracted by the two dismantling rods 7, the worker can then take the baffle 4 out of the material warehouse 1. In this way, there is no need to rely on manual force to pull the baffle 4, which improves the safety of the dismantling process.

[0058] The above are merely optional embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application. Although the embodiments of the present invention have been shown and described above, it should be understood that the above embodiments are exemplary and cannot be understood as limiting the present invention. Those skilled in the art may make changes, modifications, replacements, and variations to the above embodiments within the scope of the present invention.
