Description

Technical Field

[0001] This utility model relates to the technical field of tobacco manufacturing, and in particular to a real-time cigarette length control device and cigarette production equipment. Background Technology

[0002] In the tobacco manufacturing industry, the position of the drum float directly affects the positioning of the cigarette pack on the drum and the forming size of the cigarette. Among them, the length of the cigarette, as one of the key quality indicators, is highly dependent on the precise setting of the float position.

[0003] Traditional cigarette length control methods rely primarily on manual experience, which suffers from high subjectivity and untimely adjustments. Current technology, by introducing linear module technology into cigarette length control, enables more timely adjustment of the drum float position.

[0004] However, its adjustment relies on human experience to control the start and stop of the linear module, and the smoke group is placed after the adjustment is completed. As a result, its adjustment accuracy still depends on human experience, and the adjustment process requires repeated operation, which is cumbersome and time-consuming. Utility Model Content

[0005] The purpose of this invention is to provide a real-time cigarette length control device and cigarette production equipment, which solves the problem that the adjustment of the float ring in the prior art relies on manual experience, resulting in poor accuracy and long time consumption in the adjustment process.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0008] The mounting bracket is set up to correspond with the drum wheel;

[0009] Two opposing adjustment components are provided, with an adjustment gap between them. The drum is at least partially located within the adjustment gap. A portion of each adjustment component abuts against the float ring of the drum. Each adjustment component is provided with a drive component for driving the two adjustment components to move closer or further apart from each other. Each adjustment component has a blowhole corresponding to the smoke receiving groove of the drum.

[0010] The blowing assembly is connected to the blowing hole and blows smoke into the smoke group through the blowing hole.

[0014] Optionally, the blowing assembly includes:

[0015] A blow-off valve, wherein the air inlet of the blow-off valve is connected to an air pump;

[0016] The air tube is connected at one end to the air outlet of the blow valve and at the other end to the blow hole.

[0017] Optionally, the real-time cigarette length control device further includes:

[0018] A sealing assembly is disposed on the mounting bracket and closes the mounting bracket, and the adjusting assembly is slidably engaged with the sealing assembly.

[0019] Optionally, the adjustment component includes:

[0020] The slide is slidably connected to the mounting bracket;

[0021] The mounting base is disposed on the slide and has a sealing groove, and the sealing assembly slides through the sealing groove.

[0023] A sliding plate is mounted on the sliding base;

[0024] A cover plate is disposed opposite to and fixedly connected to the slide plate, and the sealing groove is formed between the cover plate and the slide plate.

[0025] Optionally, the slide plate has an arc-shaped outward convexity on the side near the cover plate; and / or

[0026] The cover plate is concave in an arc shape on the side closest to the slide plate.

[0027] Optionally, the sealing assembly includes:

[0028] A sealing strip is inserted through the adjustment assembly and slides in cooperation with the adjustment assembly. Both ends of the sealing strip are fixedly connected to the mounting bracket to close the mounting bracket.

[0029] Optionally, the sealing strip is made of magnetic material, and the mounting bracket is provided with a magnetic element that can attract the sealing strip.

[0030] Secondly, this utility model also provides cigarette production equipment, which includes:

[0031] abutment;

[0032] The drum wheel is mounted on the base.

[0033] The real-time cigarette length control device as described in any of the first aspects is disposed on the base and corresponds to the drum.

[0034] The beneficial effects of this utility model are:

[0035] Firstly, during length adjustment, the blowing assembly gathers the tobacco bundles placed in the tobacco receiving slots, bringing the cigarette with the nozzle and filter rod closer together. Then, the drive assembly is activated, causing two adjustment components to move closer together, which in turn moves the floats at both ends of the drum closer together, thus adjusting the length of the tobacco bundles in all the tobacco receiving slots. Therefore, when using this real-time cigarette length adjustment device, after gathering the tobacco bundles in any one of the tobacco receiving slots, the distance between the floats and the center line of the drum is adjusted by the adjustment components. This eliminates the need for repeated operations to adjust the length of the tobacco bundles in the receiving slots, effectively improving the accuracy of the adjustment process, saving adjustment time, and thus effectively improving cigarette production efficiency.

[0036] Secondly, when the cigarette production equipment is in use, the real-time cigarette length control device can quickly and accurately adjust the position of the upper float ring of the drum, saving the time spent on adjustment, and the adjustment accuracy is high, thereby effectively improving the production efficiency of the cigarette production equipment.

[0050] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It is understood that, in this second aspect, when the cigarette production equipment is in use, the real-time cigarette length control device can quickly and accurately adjust the position of the upper float ring of the drum, saving adjustment time and achieving high adjustment accuracy, thereby effectively improving the production efficiency of the cigarette production equipment. The specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only show the parts related to the present invention and not the entire structure.

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.

[0054] This utility model discloses a real-time cigarette length control device and cigarette production equipment.

[0055] Reference Figures 1 to 4 The real-time cigarette length control device includes a mounting frame 1, two opposing adjustment components 2, and a blowing component 3. The mounting frame 1 is correspondingly arranged with the drum 4; the two opposing adjustment components 2 form an adjustment gap between them, with at least a portion of the drum 4 located within the adjustment gap, and a portion of the adjustment component 2 abutting against the float ring 41 of the drum 4. Each adjustment component 2 is provided with a drive component 6, which is used to drive the two adjustment components 2 closer to or further away from each other. The adjustment component 2 has a blowing hole 21 corresponding to the cigarette receiving groove of the drum 4; the blowing component 3 communicates with the blowing hole 21 and blows the cigarette pack through the blowing hole 21.

[0056] Specifically, the mounting frame 1 is elongated and extends circumferentially along the drum 4. The mounting frame 1 includes a base 11, a connecting plate 12, a bottom plate 13, and side plates 14. The base 11 is fixedly mounted on a base platform or wall panel. The connecting plate 12 is fixedly mounted on the base 11. The bottom plate 13 and the side plates are respectively fixedly connected to two adjacent side plates of the connecting plate 12. The bottom plate 13 and the side plates 14 are also fixedly connected to each other or form an integral structure. Two side plates 14 are arranged opposite each other, so that the side plates 14 and the bottom plate 13 enclose a frame structure with a U-shaped cross-section. The fixing methods described above can all be achieved by bolting, snap-fitting, bonding, or welding, etc., and this utility model does not limit these methods.

[0057] A slide bar 15 is provided on the base plate 13 along its length. The adjusting component 2 is elongated, with one end slidingly engaged with the slide bar 15, and the other end extending away from the mounting bracket 1 and corresponding to the end face of the drum 4, such that the drum 4 is at least partially located between the two adjusting components 2, and the protruding end of the adjusting component 2 abuts against the float ring 41 of the drum 4. Each adjusting component 2 is provided with a separate drive component 6 to drive the two adjusting components 2 closer together or further apart. The drive component 6 can be a motor coupled with a lead screw or a gear rack structure. A through hole is provided in the adjusting component 2 near the smoke-receiving groove of the drum 4 as a blowing hole 21. The blowing component 3 is sealed and connected to the blowing hole 21. The blowing component 3 can generate gas at a specific pressure to blow the tobacco bundles in the smoke-receiving groove closer together. The specific pressure can be adjusted according to the actual required blowing amplitude of the tobacco bundles.

[0058] During length adjustment, the blowing assembly 3 blows the tobacco bundles placed in the tobacco receiving slots together, bringing the cigarette with the nozzle and filter rod closer together. Then, the drive assembly 6 is controlled to operate, driving the two adjustment assemblies 2 closer together. This, in turn, pushes the floats 41 at both ends of the drum 4 closer together, thus completing the length adjustment of the tobacco bundles in all tobacco receiving slots. Therefore, when using this real-time cigarette length adjustment device, after blowing the tobacco bundles in any one of the tobacco receiving slots together, the distance between the floats 41 and the center line of the drum 4 is adjusted by the adjustment assembly 2. This eliminates the need for repeated operations to complete the length adjustment of the tobacco bundles in the tobacco receiving slots, effectively improving the accuracy of the adjustment process, saving adjustment time, and thus effectively improving the production efficiency of cigarettes.

[0059] Reference Figures 4 to 6 Optionally, the adjusting assembly 2 includes an adjusting rod 22. One end of the adjusting rod 22 is slidably connected to the mounting bracket 1, and the other end is rotatably connected to an adjusting part 23, which abuts against the float ring 41 of the drum 4; wherein, the portion of the adjusting rod 22 corresponding to the smoke receiving groove of the drum 4 has a blowhole 21.

[0060] Specifically, one end of the adjusting rod 22 is slidably engaged with the slide bar 15 via a sliding structure, while the other end can bend upwards and extend to the radially upper side of the drum 4. Adjusting portions 23 are provided at both ends, and these portions are wheel-shaped and rotatably connected to the adjusting rod 22. The adjusting rod 22 protrudes upwards near the smoke-receiving groove, and a through hole 242 is formed in the protruding portion as a blowhole 21. One end of the blowhole 21 faces any smoke-receiving groove of the drum 4, and the other end communicates with the blowhole assembly 3. The diameter of the blowhole 21 can be adapted to the width of the smoke-receiving groove; this invention does not limit this. When the drum 4 is used as a primary cutting drum, the real-time cigarette length control device is located on the lower right side of the drum 4, and the adjusting rod 22 bends downwards and corresponds to the radially lower side of the drum 4. This facilitates the cutting of the drum 4 directly below after adjustment, and in this case, the blowhole 21 does not need to be provided on the adjusting rod 22.

[0061] By setting a curved adjusting rod 22, its end can not only correspond to the float ring 41 of the drum 4, but also partially protrude from the float ring 41 and provide a position for the opening of the blow hole 21. This allows the blow hole to directly face one end of the smoke receiving groove on the surface of the drum 4 without the need for additional alignment operations. When adjusting the length, only the air pressure needs to be controlled to blow the smoke in the smoke receiving groove together.

[0062] Reference Figure 2 Optionally, the blowing assembly 3 includes a blow-gathering valve 31 and an air pipe 32. The air inlet of the blow-gathering valve 31 is connected to an air pump; one end of the air pipe 32 is connected to the air outlet of the blow-gathering valve 31, and the other end is connected to the blowing hole 21.

[0063] Specifically, the blow valve 31 is fixed on the mounting bracket 1, and the air pump's injection port is connected to the air inlet of the blow valve 31 through a pipeline. The air pipe 32 is a flexible hose, and its length is designed according to the range of movement required by the adjusting component 2. Sealing structures are provided at both ends of the air pipe 32 to form a sealed connection with the two air ports respectively.

[0064] When it is necessary to blow together the smoke assembly, start the air pump and control the blowing valve 31 to open or close, so that gas at a specific pressure is ejected from the blowing hole 21, thereby blowing together the smoke assembly.

[0065] Reference Figure 6 Optionally, the real-time cigarette length control device also includes a sealing component 5. The sealing component 5 is disposed on the mounting frame 1 and closes the mounting frame 1, and the adjusting component 2 is in sliding engagement with the sealing component 5.

[0066] Specifically, the mounting bracket 1 is open on the side facing the drum 4, and the sealing component 5 is located on the open side of the mounting bracket 1. The sealing component 5 can be plate-shaped and have a long sliding hole on its side wall. The adjusting component 2 extends into the mounting bracket 1 through the sliding hole and forms a sliding connection with the mounting bracket 1. The sealing component 5 can also be sheet-shaped, which passes through the adjusting component 2 and is slidably connected with the adjusting component 2.

[0067] By setting the sealing component 5 to enclose the mounting frame 1, the interior of the mounting frame 1 can be isolated from the cigarette production process, reducing the entry of particulate matter and other pollutants in the environment into the mounting cavity and affecting the normal sliding of the adjustment component 2.

[0068] Reference Figures 7 to 11 Optionally, the adjusting assembly 2 includes a slide 24 and a mounting base 25. The slide 24 is slidably connected to the mounting bracket 1. The mounting base 25 is disposed on the slide 24 and has a sealing groove, through which the sealing assembly 5 slidably passes.

[0069] Specifically, the drive assembly 6 includes a motor and a lead screw 62. The motor is fixedly mounted in the mounting bracket 1 and is a servo geared motor. Both ends of the lead screw 62 are rotatably connected to the mounting bracket 1 via bearings, and the lead screw 62 is connected to the motor via a coupling. A slide block 24 is located within the mounting bracket 1 and has a threaded hole 241 and a through hole 242. The threaded hole 241 is threadedly connected to one of the two lead screws 62, while the through hole 242 is slidably engaged with the other lead screw 62. Two slide bars 15 are spaced apart, each with a sliding block 151. A mounting groove 243 is provided on the side of the slide block 24, which is inserted into the sliding block 151. A countersunk hole or through hole is provided through the mounting groove 243 of the slide block 24, and a screw is inserted into the countersunk hole or through hole to form a fixed connection with the sliding block 151, thereby limiting the rotation of the slide block 24 and ensuring that the slide block 24 can only slide in the extension direction of the slide bar 15. The adjusting part 23 is fixedly connected to the side of the slide block 24 away from the slider 151, thereby driving the component 6 to slide back and forth when it is running. At the same time, the slide block 24 forms a guiding engagement with another lead screw 62 to ensure that the slide block 24 will not deviate.

[0070] Mounting base 25 is fixed to the side of slide block 24 away from slider 151, and adjusting rod 22 is fixed to mounting base 25. A sealing groove is formed through the side of mounting base 25, and sealing component 5 partially passes through the sealing groove and slides in cooperation with the sealing groove. Mounting base 25 can partially extend out of the opening of mounting bracket 1, so that the sealing groove corresponds to the opening of mounting bracket 1, so that sealing component 5 is just located in the opening of mounting bracket 1.

[0071] The mounting base 25 and the mounting frame 1 are slidably connected by a slide block 24, providing an installation position for the adjusting rod 22. A sealing groove is provided in the mounting base 25, allowing the sealing component 5 to pass directly through the mounting base 25 and slide in contact with it. This ensures that the sealing component 5 can seal the mounting frame 1 without affecting the reciprocating sliding of the adjusting component 2.

[0072] Optionally, the mounting base 25 includes a slide plate 251 and a cover plate 252. The slide plate 251 is disposed on the slide base 24; the cover plate 252 is disposed opposite to and fixedly connected to the slide plate 251, and a sealing groove is formed between the cover plate 252 and the slide plate 251.

[0073] Specifically, the back of the slide plate 251 is fixedly connected to the slide base 24, while the front of the slide plate 251 is opposite to the cover plate 252. The upper and lower sides of the two can be fixedly connected, forming a through sealing groove by a gap in the middle. In this embodiment, notches are provided on the upper and lower sides of the front of the slide plate 251, and protrusions are provided on the upper and lower sides of the cover plate 252. The protrusions and notches form an insertion fit, and countersunk holes are provided on the protrusions. Screws are inserted into the countersunk holes, and threaded holes 241 are provided in the notches. Screws are threaded into the threaded holes 241, thereby fixing the cover plate 252 and the slide plate 251.

[0074] By setting up a sliding plate 251 and a cover plate 252 to form a sealing groove, the sealing component 5 can be separated from the sliding plate 251 and the cover plate 252 during installation. The sealing component 5 is passed through the sealing groove, and then the cover plate 252 is fixedly connected to the sliding plate 251 to form a sealing groove. This not only facilitates the installation of the sealing component 5, but also allows for adjustment of the contact pressure between the sealing groove and the sealing component 5, ensuring that the adjusting component 2 does not experience too much frictional resistance when sliding.

[0075] Optionally, the side of the skateboard 251 closest to the cover plate 252 is curved and protrudes outward.

[0076] Specifically, the front and middle part of the slide plate 251 is arc-shaped and protrudes outward so that the opening of the sealing groove can better match the opening of the mounting bracket 1. At this time, the part of the sealing component 5 that passes through the sealing groove can be made of flexible material so that it can fit into the arc-shaped sealing groove.

[0077] Optionally, the side of the cover plate 252 closest to the slide plate 251 is concave in an arc shape.

[0078] Specifically, the side of the cover plate 252 can be individually formed into a concave arc shape to reduce the contact area with the sealing component 5, thereby reducing the frictional resistance generated during sliding. The concave arc shape can also match the convex arc shape to form an arc-shaped sealing groove, so that the opening of the sealing groove can correspond exactly to the opening of the mounting bracket 1. When the part of the sealing component 5 that passes through the sealing groove is made of flexible material, the sealing component 5 will only bulge in the adjusting component 2 part, while the rest will remain in the opening of the mounting bracket 1 to ensure a good seal for the mounting bracket 1.

[0079] Optionally, the sealing assembly 5 includes a sealing strip 51. The sealing strip 51 passes through the adjusting assembly 2 and slides in engagement with the adjusting assembly 2. Both ends of the sealing strip 51 are fixedly connected to the mounting bracket 1 to close the mounting bracket 1.

[0080] Specifically, fixing strips 52 can be provided at both ends of the sealing strip 51 along its length. The fixing strips 52 are fixedly connected to the mounting bracket 1, such as by screws or snap-fit, to fix the sealing strip 51 at the opening of the mounting bracket 1. The sealing strip 51 has a certain degree of flexibility, allowing it to pass through the sealing groove and protrude outward at the sealing groove, so that the adjusting component 2 can slide smoothly. The remaining parts can fit tightly against the opening of the mounting bracket 1 and be fixed by magnetic attraction or zipper.

[0081] The mounting bracket 1 is sealed by setting a sealing strip 51, and the sealing strip 51 and the mounting base 25 form a sliding fit. Without affecting the reciprocating sliding of the adjustment component 2, it can effectively seal the opening of the mounting bracket 1.

[0082] Optionally, the sealing strip 51 is made of magnetic material, and the mounting bracket 1 is provided with a magnetic element that can attract the sealing strip 51.

[0083] Specifically, the sealing strip 51 can be made of thin steel sheet, and a mounting strip is formed by bending the side plate 14 of the mounting bracket 1. The mounting strip partially overlaps with the sealing strip 51, and a magnetic element is installed on the side of the mounting strip to attract the upper and lower sides of the sealing strip 51. This allows the adjusting component 2 to separate the sealing strip 51 from the magnetic element when it slides, and when the adjusting component 2 slides past, the upper and lower sides of the sealing strip 51 are attracted by the magnetic element, thereby achieving automatic sealing of the opening of the mounting bracket 1.

[0084] The cigarette production equipment includes a base 7, a drum 4, and a real-time cigarette length control device as described above. The drum 4 is located on the base 7; the real-time cigarette length control device is located on the base 7 and corresponds to the drum 4.

[0085] When in use, the cigarette production equipment has a real-time cigarette length control device that can quickly and accurately adjust the position of the upper floating ring 41 of the drum 4, saving adjustment time and providing high adjustment accuracy, thereby effectively improving the production efficiency of the cigarette production equipment.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
