Description

Technical Field

[0001] This utility model relates to the field of cigarette conveying technology, and in particular to a cigarette conveying fixture and cigarette equipment. Background Technology

[0002] Conveying devices are needed in many stages of cigarette production, such as the process of conveying and packing tobacco. Specifically, after cigarettes are packed into cartons, they are transported by conveyor belt from the production site to the packing location outside the factory for easy packing, facilitating sales, express delivery, etc. During this process, it is necessary to ensure the correct conveying direction and position of the cigarettes so that they maintain the correct orientation when they reach the other end for easy packing.

[0003] The lack of positioning or correction components on the conveyor belts of existing transmission devices can lead to positional deviations of the cigarette packs during transportation. This can result in inconsistent orientations when transported to the other end, affecting packing, or the cigarettes getting stuck and colliding with each other, causing them to fall onto the conveyor belt and resulting in machine malfunctions.

[0004] Therefore, there is an urgent need to propose a cigarette conveying fixture and cigarette rolling equipment to solve the above problems. Utility Model Content

[0010] A lead screw, which has external threads with opposite directions of rotation, is positioned above the conveyor belt along the width direction of the conveyor belt, and its two ends are rotatably connected to the frame.

[0011] Two sets of limiting components are provided. Each set of limiting components includes a limiting plate, a connecting member, and a mating member. The two limiting plates are located on opposite sides of the smoke body along the width direction of the conveyor belt. One end of the connecting member is connected to the corresponding limiting plate, and the other end of the connecting member is provided with an internal thread. The internal thread is adapted to the corresponding external thread on the lead screw to connect the lead screw. The mating member connects the frame and the connecting member and can restrict the connecting member from rotating with the lead screw. The rotation of the lead screw can only drive the two connecting members to move along the width direction of the conveyor belt.

[0012] As an optional technical solution for cigarette conveying fixture, the cigarette conveying fixture also includes a mounting frame, which is mounted on the frame along the width direction of the conveyor belt, and the two ends of the lead screw are rotatably connected to the mounting frame.

[0013] As an optional technical solution for a cigarette conveying fixture, the connecting member is movably connected to the mounting frame through the mating member.

[0014] As an optional technical solution for a cigarette conveying fixture, the mating component includes a slider, which is fixed to the end of the connector away from the limiting plate. The mounting bracket is provided with a groove extending along the width direction of the conveyor belt on the side facing the conveyor belt, and the slider is engaged in the groove and can slide within the groove.

[0015] As an optional technical solution for a cigarette conveying fixture, the connecting component includes a connecting rod and a sleeve. The two ends of the connecting rod are respectively connected to the limiting plate and the sleeve, and the sleeve is fitted onto the lead screw.

[0016] As an optional technical solution for the cigarette conveying fixture, the connecting component further includes a connecting plate, and the connecting rod is connected to the limiting plate through the connecting plate.

[0017] As an optional technical solution for a cigarette conveying fixture, the limiting plate is provided with a slot, the slot is adapted to the shape of the connecting plate, and the connecting plate can be locked in the slot.

The bottom of the avoidance groove is connected to the slot, and the connecting plate can be assembled into the slot along the width of the conveyor belt.

[0019] As an optional technical solution for the cigarette conveying fixture, the limiting component also includes two sets of bolts, which are located on both sides of the clearance groove along the conveyor belt conveying direction, and the bolts pass through and connect the limiting plate and the connecting plate.

[0020] Another objective of this invention is to provide a cigarette rolling device that has a good effect on the conveying and limiting correction of cigarette bodies and is highly versatile.

[0021] To achieve this objective, the present invention adopts the following technical solution:

[0022] The cigarette making equipment includes the aforementioned cigarette conveying fixture, wherein the cigarette body can be placed on the conveyor belt of the cigarette conveying fixture and can be limited by the two limiting plates.

[0023] The beneficial effects of this utility model are:

[0024] The present invention provides a cigarette conveying fixture comprising a frame, a conveyor belt, a lead screw, and two sets of limiting components. The frame provides support and fixation, and the conveyor belt is mounted on the frame for conveying the cigarette body. The two sets of limiting components can respectively limit the cigarette body on both sides along the width direction of the conveyor belt (perpendicular to the conveying direction of the conveyor belt), preventing the cigarette body from tilting during conveying and correcting its orientation during the conveying process. The lead screw has external threads with opposite directions of rotation, and both ends are rotatably connected to the frame, allowing it to rotate. Each set of limiting components includes a limiting plate, a connecting piece, and a mating piece. The two limiting plates are located on opposite sides of the cigarette body, clamping and limiting the cigarette body. One end of the connecting piece is connected to the corresponding limiting plate, and the other end has an internal thread to connect to the lead screw. The mating piece connects the frame and the connecting piece, restricting the connecting piece from rotating with the lead screw, so that the rotation of the lead screw can only drive the two connecting pieces to move along the width direction of the conveyor belt. The rotation of the lead screw can drive two limit plates to move closer or further apart through two connecting parts to accommodate smoke bodies of different widths, thus improving the versatility of the smoke conveying fixture. The mating parts can restrict the connecting parts from rotating with the lead screw when the lead screw rotates, preventing the connecting parts and limit plates from shifting, allowing the connecting parts to only make linear movement adjustments, and improving the limit correction effect of the limit assembly.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. 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.

[0036] This embodiment provides a cigarette conveying fixture that can correct the orientation of cigarettes during the conveying process, and has good limiting correction effect and strong versatility.

[0037] Specifically, such as Figures 1 to 4As shown, the cigarette conveying fixture includes a frame 100, a conveyor belt 210, a lead screw 300, and two sets of limiting components 400. The conveyor belt 210 is mounted on the frame 100, and the cigarette body 10 can be placed on the conveyor belt 210 for conveying. The conveyor belt 210 can be set horizontally or at an angle; the surface of the conveyor belt 210 needs to be treated with anti-slip material to prevent the cigarette body 10 from slipping on the conveyor belt 210, especially when the conveyor belt 210 is set at an angle. In this embodiment, the conveyor belt 210 is set horizontally. The lead screw 300 has external threads with opposite directions of rotation (not shown in the figure). The lead screw 300 is set above the conveyor belt 210 along the width direction of the conveyor belt 210 (perpendicular to the conveying direction of the conveyor belt 210), and both ends are rotatably connected to the frame 100. Each set of limiting components 400 includes a limiting plate 410, a connector 420, and a mating component 430. The two limiting plates 410 are located on opposite sides of the smoke body 10 along the width direction of the conveyor belt 210. One end of the connector 420 is connected to the corresponding limiting plate 410, and the other end of the connector 420 is provided with an internal thread (not shown in the figure). The internal thread is adapted to the corresponding external thread on the lead screw 300 to connect the lead screw 300. The mating component 430 connects the frame 100 and the connector 420, and can restrict the connector 420 from rotating with the lead screw 300. The rotation of the lead screw 300 can only drive the two connectors 420 to move along the width direction of the conveyor belt 210.

[0038] Based on the above design, the frame 100 serves as a support and fixation unit, and the conveyor belt 210 is set on the frame 100 for conveying the smoke body 10. The two sets of limiting components 400 can limit the smoke body 10 on both sides along the width direction of the conveyor belt 210, so as to prevent the smoke body 10 from tilting when it is conveyed by the conveyor belt 210 and to correct the orientation of the smoke body 10 during the conveying process. The lead screw 300 has external threads with opposite directions of rotation, and both ends are rotatably connected to the frame 100, allowing it to rotate. Each set of limiting components 400 includes a limiting plate 410, a connecting member 420, and a mating member 430. The two limiting plates 410 are located on opposite sides of the smoke body 10, clamping the smoke body 10 and limiting its movement. One end of the connecting member 420 is connected to the corresponding limiting plate 410, and the other end has an internal thread to connect to the lead screw 300. The mating member 430 connects the frame 100 and the connecting member 420, and can restrict the connecting member 420 from rotating with the lead screw 300, so that the rotation of the lead screw 300 can only drive the two connecting members 420 to move along the width direction of the conveyor belt 210. The rotation of the lead screw 300 can drive the two limit plates 410 to move closer or further apart through the two connecting parts 420 to accommodate smoke bodies 10 of different widths, thereby improving the versatility of the smoke conveying fixture. The mating part 430 can restrict the connecting parts 420 from rotating with the lead screw 300 when the lead screw 300 rotates, preventing the connecting parts 420 and the limit plates 410 from shifting, so that the connecting parts 420 can only make linear movement adjustments, thereby improving the limit correction effect of the limit assembly 400.

[0039] In this embodiment, the smoke conveying fixture further includes a first driving component 220, a drive shaft 230, a driven shaft 240, a drive roller 250, and a driven roller 260. The first driving component 220 can be a servo motor, etc. The drive roller 250 and the driven roller 260 are respectively fixed to the drive shaft 230 and the driven shaft 240. Both the drive shaft 230 and the driven shaft 240 are rotatably connected to the frame 100, and the drive shaft 230 and the driven shaft 240 are spaced apart along the conveying direction of the conveyor belt 210. The conveyor belt 210 is sleeved on the drive roller 250 and the driven roller 260. The first driving component 220 is fixed to one side of the frame 100 along the width direction of the conveyor belt 210 (outer side of the frame 100), and the output end of the first driving component 220 is connected to the drive shaft 230.

[0040] The conveyor belt 210 can be driven by friction, that is, it transmits power by the friction between the conveyor belt 210 and the drive rollers (drive roller 250 and driven roller 260). The conveyor belt 210 can be made of materials such as rubber, PVC, and PU, and is mostly a flat belt or a patterned belt. The surfaces of the drive roller 250 and the driven roller 260, especially the surface of the drive roller 250, need to be coated (rubber, polyurethane) or grooved to increase the coefficient of friction. The conveyor belt 210 needs to be equipped with tensioning components (such as screw tensioning, gravity tensioning, etc.) to ensure that the conveyor belt 210 maintains appropriate tension. The arc of the contact between the conveyor belt 210 and the drive roller 250 is large enough (usually greater than or equal to 180 degrees), that is, to ensure sufficient wrap angle to prevent the conveyor belt 210 from slipping. Other parameter designs are also involved in the friction drive process of the conveyor belt 210, but since they are mature existing technologies in this field, they will not be described in detail here.

[0041] The conveyor belt 210 can also be driven by a synchronous belt. The synchronous belt drive achieves slip-free transmission by the meshing of the teeth of the synchronous belt (conveyor belt 210) with the pulley. The teeth on the inner side of the synchronous belt precisely mesh with the grooves of the pulley, directly transmitting power (not relying on friction) and completely eliminating slippage. However, a tensioning component is still required to ensure that the synchronous belt maintains appropriate tension. Other parameter designs are also involved in the synchronous belt drive process of the conveyor belt 210. Since these are mature existing technologies in this field, they will not be described in detail here.

[0042] Of course, in other embodiments, the conveyor belt 210 can also be driven by a chain. The chain drive of the conveyor belt 210 achieves power transmission through the meshing of the chain and the sprocket. The specific transmission method is also a relatively mature existing technology in the field, and will not be described in detail here.

[0043] Optionally, the cigarette conveying fixture also includes a mounting frame 500, which is mounted on the frame 100 along the width direction of the conveyor belt 210. The two ends of the lead screw 300 are rotatably connected to the mounting frame 500, which not only facilitates the installation and fixing of the lead screw 300, but also increases the height between the lead screw and the conveyor belt 210, providing sufficient installation space for the limit assembly 400.

[0044] Furthermore, the connector 420 is movably connected to the mounting frame 500 via the mating member 430. Compared to the mating member 430 being movably connected to the frame 100, the connection of the mating member 430 to the mounting frame 500 allows the mating member 430 to better restrict the rotation of the connector 420 without affecting the linear movement of the connector 420.

[0045] Specifically, the mating part 430 includes a slider, which is fixed to one end of the connector 420 away from the limiting plate 410. The mounting bracket 500 is provided with a groove extending along the width direction of the conveyor belt 210 on the side facing the conveyor belt 210. The slider is engaged in the groove and can slide in the groove.

[0046] In this embodiment, the smoke conveying fixture also includes a second driving component 600, which is fixed to one side of the mounting frame 500 along the width direction of the conveyor belt 210 (outer side of the mounting frame 500). The output end of the second driving component 600 is connected to a lead screw 300, driving the lead screw 300 to rotate. The second driving component 600 can be a servo motor, etc.

[0047] Optionally, the connector 420 includes a connecting rod 421 and a sleeve 422. The two ends of the connecting rod 421 are respectively connected to the limiting plate 410 and the sleeve 422. The sleeve 422 is sleeved on the lead screw 300. The sleeve 422 increases the connection strength between the lead screw 300 and the connector 420.

[0048] In this embodiment, the slider is connected to the outer wall of the sleeve 422.

[0049] Furthermore, the connector 420 also includes a connecting plate 423, through which the connecting rod 421 is connected to the limiting plate 410. The connecting plate 423 and the limiting plate 410 are in close contact, which increases the contact area between the connector 420 and the limiting plate 410 and improves the connection strength between the connector 420 and the limiting plate 410.

[0050] In order to increase the connection strength between the limiting plate 410 and the connecting plate 423, the limiting plate 410 is provided with a slot 411. The slot 411 is adapted to the shape of the connecting plate 423, and the connecting plate 423 can be locked in the slot 411, making the locking connection convenient.

[0051] Furthermore, the slot 411 extends through the width of the conveyor belt 210, and the limiting plate 410 has an avoidance groove 412 on the side opposite to the conveyor belt 210. The bottom of the avoidance groove 412 is connected to the slot 411. The connecting plate 423 can be assembled into the slot 411 along the width of the conveyor belt 210, and the slot 411 is set inside the limiting plate 410, so that the connecting plate 423 is embedded in the limiting plate 410, further improving the connection strength between the connecting plate 423 and the limiting plate 410.

[0052] The limiting assembly 400 also includes two sets of bolts 440, which are located on both sides of the clearance groove 412 along the conveying direction of the conveyor belt 210. The bolts 440 pass through the connecting limiting plate 410 and the connecting plate 423 to strengthen and fix the limiting plate 410 and the connecting plate 423.

[0053] It should be noted that the cigarette conveying fixture also includes a collection box 700, which is located on one side of the frame 100 along the conveying direction of the conveyor belt 210. The cigarette body 10 is conveyed to the collection box by the conveyor belt 210.

[0054] This embodiment also provides a cigarette rolling device, which has a good effect on the conveying and limiting correction of cigarette bodies and is highly universal.

[0055] Specifically, the cigarette-making equipment includes the aforementioned cigarette conveying fixture. A cigarette body 10 can be placed on the conveyor belt 210 of the fixture and is limited by two limiting plates 410 to prevent the cigarette body 10 from tilting during conveying with the conveyor belt 210, thus correcting its orientation during transport. Furthermore, the rotation of the lead screw 300 can drive the two limiting plates 410 closer together or further apart via two connecting parts 420 to accommodate cigarette bodies 10 of different widths, improving the versatility of the cigarette conveying fixture and consequently, the versatility of the cigarette-making equipment. A mating part 430 restricts the connecting part 420 from rotating with the lead screw 300, preventing misalignment between the connecting part 420 and the limiting plates 410, allowing the connecting part 420 to only perform linear movement adjustment, thus improving the limiting and correcting effect of the limiting component 400 and consequently, the correcting effect of the cigarette-making equipment.

[0056] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
