Description

Technical Field

[0001] This utility model relates to the field of cigarette equipment maintenance technology, and in particular to a chain plate replacement device and cigarette equipment. Background Technology

[0002] In cigarette manufacturing equipment, the chain plate system is an important component for storing and transporting cigarettes. It requires high operational stability and has a complex chain plate structure. Replacing the chain plate during routine maintenance is a high-difficulty and high-intensity operation.

[0003] Currently, the lack of guiding structures during chain plate replacement leads to misalignment at the chain plate's interface with the guide rail, causing chain plate wear and affecting equipment stability. Furthermore, the chain plate is prone to skew and jamming when entering the guide groove, often requiring frequent manual intervention, making the operation difficult and resulting in low replacement efficiency. Additionally, the replacement process relies heavily on operator experience, making it difficult to guarantee replacement quality.

[0004] Therefore, there is an urgent need to propose a chain plate replacement device and cigarette rolling equipment to solve the above-mentioned technical problems. Utility Model Content

[0010] Optionally, the end of the first limiting arm forming the first guide channel is provided with a first inclined surface, and the end of the second limiting arm forming the first guide channel is provided with a second inclined surface. The second inclined surface is disposed opposite to the first inclined surface and is inclined in a direction away from each other.

[0011] Optionally, the mounting angle of the limiting member relative to the first limiting arm and the second limiting arm is adjustable.

[0012] Optionally, on one side of the arc-shaped limiting segment where the curved guide segment is provided, a first connector and a second connector are respectively provided on opposite sides of the arc-shaped limiting segment. The first connector abuts against the first limiting arm, and the second connector abuts against the second limiting arm. The first connector is provided with a first through hole, and the second connector is provided with a second through hole. The fastening assembly includes a first bolt and a nut.

Simultaneously, the new chain plate is manually guided through the first guide channel and brought into contact with the guide roller on the equipment. The roller's rolling motion drives the new chain plate inward. Throughout this process, the first guide channel continuously guides the position of the new chain plate, preventing it from deviating during introduction and improving assembly quality and consistency. Furthermore, this chain plate replacement device eliminates the need for manual intervention in both the removal of the old chain plate and the introduction of the new one, reducing worker workload and increasing replacement efficiency.

[0018] In addition, the chain plate replacement device is installed at the chain plate inlet and outlet channels without changing the original structure of the equipment.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] In the description of this embodiment, the terms "upper," "lower," "left," and "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.

[0027] This embodiment provides a chain plate replacement device that can guide the import and export of chain plates, thereby automating chain plate replacement, reducing replacement difficulty, and improving replacement quality and efficiency.

[0028] For equipment requiring chain plate replacement, the chain plate replacement device can be installed at the chain plate inlet and outlet channels, which are used for the introduction and export of chain plates. This installation does not require altering the original structure of the equipment, and any disassembly or maintenance will not affect the operation of other modules, demonstrating good compatibility.

[0029] Specifically, such as Figures 1-3 As shown, the chain plate replacement device includes a frame 100 and a limiting member 200. The frame 100 has a first guide channel 101 and a second guide channel 102. The first guide channel 101 guides the introduction of new chain plates, and the second guide channel 102 guides the exit of old chain plates. The limiting member 200 is connected to the frame 100. The limiting member 200 includes an arc-shaped limiting section 210 and a curved guide section 220 smoothly connected to the arc-shaped limiting section 210. The arc-shaped limiting section 210 is installed below the sprocket and supports the old or new chain plate that mates with the sprocket. The curved guide section 220 guides the old chain plate into the second guide channel 102.

[0030] This chain plate replacement device can function both when the equipment is running and when the equipment is stopped for chain plate replacement.

[0031] During equipment operation, the arc-shaped limiting section 210 supports the chain plate below the sprocket, enabling the chain plate to reliably mesh with the sprocket and reducing the risk of the chain plate detaching from the sprocket due to gravity or other reasons. In other words, the chain plate replacement device not only does not need to be removed during normal equipment operation, but also improves the stability of equipment operation.

[0032] When the equipment is shut down to replace the chain plate, the chain plate is disconnected at the inlet and outlet channels. As the sprocket rotates, the old chain plate is guided into the second guide channel 102 by the curved guide section 220, reducing the risk of jamming during the disassembly of the old chain plate. Simultaneously, the new chain plate is manually passed through the first guide channel 101 and brought into contact with the guide roller on the equipment. The roller's rolling motion drives the new chain plate inward. Throughout this process, the first guide channel 101 continuously guides the position of the new chain plate, preventing it from deviating during introduction and improving the assembly quality and consistency. Furthermore, this chain plate replacement device eliminates the need for manual intervention in both the removal of the old chain plate and the introduction of the new one, reducing worker workload and increasing replacement efficiency.

[0033] Optionally, see [link to relevant documentation] Figures 1-3In one possible embodiment, the arc-shaped limiting segment 210 and the curved guide segment 220 form an integral structure. This arrangement facilitates processing and improves the connection strength between the arc-shaped limiting segment 210 and the curved guide segment 220.

[0034] Optionally, both the arc-shaped limiting section 210 and the curved guide section 220 are smoothly arranged to reduce friction with the chain plate.

[0035] Further, see also Figure 1 and Figure 2 In one possible embodiment, the frame 100 includes a first limiting arm 110 and a second limiting arm 120. The first limiting arm 110 and the second limiting arm 120 are arranged parallel to each other to form a limiting space. A guide shaft 130 is provided between the first limiting arm 110 and the second limiting arm 120, dividing the limiting space into a first guide channel 101 and a second guide channel 102. One end of the arc-shaped limiting segment 210, which has a curved guide segment 220, is mounted between the first limiting arm 110 and the second limiting arm 120 via a fastening assembly 300. The curved guide segment 220 is located within the second guide channel 102. This frame 100 has a simple structure and is easy to manufacture and assemble.

[0036] Understandably, the distance between the first limiting arm 110 and the second limiting arm 120 can be set according to the width of the chain plate, so that the chain plate and the first limiting arm 110 and the second limiting arm 120 fit with a small gap. This setting makes the limiting effect of the first limiting arm 110 and the second limiting arm 120 on the chain plate better, reducing the risk of the chain plate shifting during the introduction and export process.

[0037] Optionally, a guide roller 140 is sleeved on the guide shaft 130, and the guide roller 140 can rotate around the guide shaft 130. During the introduction of a new chain plate, the new chain plate can contact the guide roller 140 to support it. Furthermore, since the guide roller 140 can roll, the friction between the guide roller 140 and the new chain plate is small, which improves the smoothness of the introduction of the new chain plate.

[0038] Optionally, an elastic protective sleeve can be installed over the guide roller 140. The elastic protective sleeve provides flexible support for the new chain plate, further reducing the risk of wear on the new chain plate during the introduction process.

[0039] Further, see also Figure 1 and Figure 2The first limiting arm 110 has a first inclined surface 111 at its end forming the first guide channel 101, and the second limiting arm 120 has a second inclined surface 121 at its end forming the first guide channel 101. The second inclined surface 121 is positioned opposite to the first inclined surface 111 and is inclined in a direction away from each other. This arrangement creates a "flared" structure on the side of the first guide channel 101 away from the guide shaft 130, making it easier for workers to place new chain plates into the first guide channel 101.

[0040] Optionally, see [link to relevant documentation] Figure 1 and Figure 2 The end of the first limiting arm 110 forming the first guide channel 101 can be configured with a reduced width, and the structure of the second limiting arm 120 is the same as that of the first limiting arm 110. This configuration can ensure the limiting effect, reduce the contact area with the new chain plate, thereby reducing the risk of wear on the new chain plate. At the same time, it can also reduce the use of materials, which helps to reduce the overall weight of the chain plate replacement device.

[0041] Furthermore, the installation angle of the limiting member 200 relative to the first limiting arm 110 and the second limiting arm 120 is adjustable. This configuration allows the position of the frame 100 to be adjusted according to the needs of equipment operation, preventing the frame 100 from obstructing the installation or operation of other components, thereby improving the versatility of the chain plate changing device.

[0042] Optionally, on the side of the arc-shaped limiting segment 210 where the curved guide segment 220 is provided, a first connector 211 and a second connector 212 are respectively provided on opposite sides of the arc-shaped limiting segment 210. The first connector 211 abuts against the first limiting arm 110, and the second connector 212 abuts against the second limiting arm 120. By providing the first connector 211 and the second connector 212, the installation position of the arc-shaped limiting segment 210 can be defined. In one possible embodiment, the first connector 211 and the second connector 212 have the same length, so that the arc-shaped limiting segment 210 is located in the middle position of the first limiting arm 110 and the second limiting arm 120. Of course, in other embodiments, the lengths of the first connector 211 and the second connector 212 can also be different, depending on actual needs.

[0043] The first connecting member 211 has a first through hole, and the second connecting member 212 has a second through hole. The fastening assembly 300 includes a first bolt 310 and a nut 320. The first bolt 310 is sequentially inserted through the second limiting arm 120, the second through hole, the arc-shaped limiting section 210, the first through hole, and the first limiting arm 110, and is connected to the nut 320. With this configuration, when adjusting the angle between the limiting member 200 and the frame 100, the nut 320 can be loosened, the frame 100 manually rotated to the desired angle, and then the nut 320 tightened to secure it. This fastening assembly 300 has a simple structure, is easy to assemble, and the angle adjustment of the limiting member 200 relative to the first limiting arm 110 and the second limiting arm 120 is also relatively convenient.

[0044] Optionally, see [link to relevant documentation] Figure 1 and Figure 2 In one possible embodiment, the portion of the first bolt 310 extending out of the nut 320 is connected to the equipment. That is, the first bolt 310 serves both to connect the limiting member 200, the first limiting arm 110, and the second limiting arm 120, and to install the frame 100 onto the equipment. This arrangement saves on the use of parts and facilitates assembly.

[0045] A third connector 213 is provided on the side of the arc-shaped limiting section 210 away from the curved guide section 220. The third connector 213 is used to abut against the equipment. The third connector 213 has a third through hole, and a second bolt 214 passes through the arc-shaped limiting section 210 and the third through hole to connect with the equipment. By setting the third connector 213 to abut against the equipment, the installation position of the limiting member 200 can be limited to ensure that the limiting member 200 meets the installation requirements. The installation of the limiting member 200 and the equipment is achieved by the second bolt 214, which has a simple structure and is easy to assemble.

[0046] Further, see also Figure 2 A washer 330 can be fitted onto the end where the first bolt 310 is connected to the nut 320. The washer 330 is located between the nut 320 and the second limiting arm 120, and is used to make the nut 320 abut against the equipment. This arrangement helps to improve the stability of the connection between the frame 100 and the equipment.

[0047] This embodiment also provides a cigarette-making device, including a chain plate, a sprocket, and the aforementioned chain plate replacement device. The chain plate cooperates with the sprocket, and the chain plate replacement device is installed at the chain plate inlet and outlet channels.

[0048] Because of the aforementioned chain plate replacement device, this cigarette-making equipment has excellent efficiency and quality in replacing chain plates.

[0049] 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.
