Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, and in particular to a chain splitter specifically for high-ventilation mesh belt machines. Background Technology

[0002] In the tobacco threshing and re-drying process, the air separator, as a crucial leaf and stem separation device, primarily functions to separate free leaves, stems, and incompletely torn leaves using the inertia, gravity, and levitation force of the material. The quality of its air separation directly impacts the achievement of threshing targets. The air separator uses a high-powered fan to pump air into the lower chamber. The air passes through a conveyor belt at the bottom and enters the air separator chamber as suspended air for separation. Currently, the air in the workshop's air separator needs to pass through two layers of conveyor belts before entering the chamber for separation. The permeability of a single layer is calculated to be only 33.3%, and the permeability of a double layer will be far lower than 33.3%. The conveyor belts severely hinder energy efficiency, and the resulting air resistance affects separation efficiency. Furthermore, the increased air resistance lowers the air velocity in the lower chamber, leading to higher pressure and dust accumulation in the lower chamber, clogging the air ducts and degrading equipment performance. In existing technologies, reducing the wind resistance of conveyor belts and increasing air permeability is a major technological breakthrough for improving the utilization of air separators. Current conventional methods involve using woven large-aperture mesh to significantly increase air permeability, or using a single mesh sheet spanning multiple chain links to reduce the inherent impact of the mesh on air permeability. However, these methods still require at least two layers of mesh belts, resulting in significant wind resistance. The applicant proposes a scheme using a double chain driven by a sprocket system to open the lower layer of the mesh belt, allowing it to stand upright and thus reducing wind resistance and increasing air permeability. However, a key challenge is ensuring that the mesh belt can open and stand upright at the lower layer without affecting normal transport, and also close at the top layer. More importantly, the double-chain transport method requires ensuring that the mesh belt, connected to both chains, remains on the same plane at the top and opens and separates at the bottom. Existing technologies do not offer corresponding solutions for this. Summary of the Invention

[0003] The purpose of this invention is to overcome the problem in the prior art of how to make the mesh belt connect two chains simultaneously so that they are on the same plane at the top and can be separated at the bottom, and to provide a chain splitter for mesh belt machines with high ventilation rate.

[0004] The objective of this invention is achieved through the following technical solution: a chain splitter for a high-ventilation-rate mesh belt machine, comprising an inner chain and an outer chain; a third connecting plate is connected to the outer chain plate of the inner chain, a first connecting plate is connected to the outer chain plate of the outer chain, a second connecting plate is connected to the first connecting plate, the first connecting plate spans over the inner chain so that the second connecting plate and the third connecting plate are positioned opposite each other, a chain plate locking plate is provided on the second connecting plate, and another chain plate locking plate is provided on the third connecting plate, with the two chain plate locking plates being positioned in close contact with each other.

[0005] Optionally, one end of the first connecting plate is fixedly mounted on the top of the outer chain plate of the outer chain, and the second connecting plate is rotatably mounted on the first connecting plate via a pivot; the third connecting plate is rotatably mounted on the inner chain via a pivot.

[0007] Optionally, the first connecting plate is L-shaped, the second connecting plate is L-shaped, and the third connecting plate is L-shaped. The connecting plates of the second and third connecting plates each occupy half of the rotation axis and can fit together.

[0008] Optionally, the two chain plate snap-fit ​​plates are fastened to the second connecting plate and the third connecting plate respectively by screws.

[0009] Optionally, a lower chain plate frame and an upper chain plate frame are provided at the joint of the two chain plate snap-fit ​​plates. The lower chain plate frame and the upper chain plate frame are attached to each other. A hinge connection rotation structure is provided at the joint of the lower chain plate frame and the upper chain plate frame. The hinge connection rotation center is not provided with a rotation shaft.

[0010] Optionally, the nesting center of the hinge connection rotation structure is located on the rotation center axis between the third connecting plate and the second connecting plate.

[0011] Optionally, transverse connecting screw holes for fastening the connection are provided on the second connecting plate and the third connecting plate.

[0012] Optionally, the lower chain plate frame and the upper chain plate frame are set in an L-shape, with the two chain plate locking plates located on the inside.

[0013] Optionally, a connecting plate is vertically installed on the top of the outer chain plate of the outer chain, and the first connecting plate is connected to the vertical connecting plate on the outer chain plate of the outer chain by screws.

[0014] The present invention has the following advantages: The device uses a first connecting plate to cross over the inner chain, so that the second connecting plate and the third connecting plate are positioned opposite each other, allowing the mesh belt to connect two chains simultaneously. This ensures that the two chains are on the same plane at the top and can also be separated at the bottom. Ultimately, this allows for better coordination between the two chains. During use, the mesh belt can be opened in layers at the lower level of transportation, allowing the mesh belt to stand upright without affecting normal transport. This reduces wind resistance and increases ventilation. Attached Figure Description

[0027] like Figure 3 The image shows a chain splitter specifically designed for high-ventilation-rate mesh belt machines. This chain splitter is primarily used in high-ventilation-rate mesh belt machines. Specifically, high-ventilation-rate mesh belt machines are used for... Figure 1 and Figure 2 As shown, in another embodiment, a key aspect of this device is how the sprocket system 2 enables the inner and outer chains to open up the lower layers during transmission rotation, allowing the mesh belt to separate and stand upright. For example... Figure 2As shown, in this device, the two chains are layered by combining a double-chain transmission with a sprocket system 2. Specifically, the sprocket system 2 includes a driven wheel 21, a driving wheel 22, a first guide wheel 23, a second guide wheel 24, a third guide wheel 25, and a fourth guide wheel 26. The driven wheel 21 and the driving wheel 22 are arranged on the same horizontal plane, and the motor 7 is connected to the shaft of the driving wheel 22 to provide power input. The fact that the driven wheel 21 and the driving wheel 22 are located on the same plane ensures that the conveyor belt is level at this point, making the entire conveyor belt surface horizontal and sealed, thus facilitating material conveying. The first guide wheel 23 and the third guide wheel 25 are arranged on the same horizontal plane and located below the driven wheel 21 and the driving wheel 22; the second guide wheel 24 and the fourth guide wheel 26 are arranged on the same horizontal plane and located below the first guide wheel 23 and the third guide wheel 25. Thus, the sprocket system 2 is actually divided into three layers: a top conveying layer and a lower separate layer. Conventional mesh belt machines actually achieve transmission by connecting the driven wheel 21 and the driving wheel 22, and they only have two layers, upper and lower. However, the upper layer of this device remains unchanged. When the lower guide wheel is used to divide the traditional lower layer into two layers, the double chain structure guides the two chains to different layers at the guide wheel, so that the mesh belt stands up.

[0028] In another embodiment, the double-chain structure combined with guide layers allows the mesh belt to stand upright at the bottom. However, ensuring its smooth operation is crucial; incorrect guide wheel positioning can easily lead to locking. This embodiment provides a specific sprocket arrangement structure, such as... Figure 2As shown, this device positions the first guide wheel 23 below the inner side of the driving wheel 22, the third guide wheel 25 below the inner side of the driven wheel 21, the second guide wheel 24 below the inner side of the first guide wheel 23, and the fourth guide wheel 26 below the outer side of the third guide wheel 25 and below the inner side of the driven wheel 21. Thus, when the chain rotates counterclockwise, the inner and outer chains, along with the two chain plate holders 5, reach the bottom of the fourth guide wheel 26. Since the chain is layered by the two guide wheels at this point, the inner chain 41 moves upward via the third guide wheel 25, while the outer chain 42 continues to move downward. At this point, the initial chain plate fixing frame 5 moves upward to the middle layer with the mesh belt. As the inner chain 41 carries the chain plate fixing frame 5 past the third guide wheel 25, the outer chain 42 carries the subsequent two chain plate fixing frames 5 back to the bottom of the fourth guide wheel 26. Similarly, since the chain is layered here, the inner chain 41 moves upward through the third guide wheel 25, while the outer chain 42 continues to move downward. In this way, the two chain plate fixing frames 5 connected by a mesh belt are simultaneously on the upper and lower layers, one on the upper layer and the other on the lower layer. Since the inner chain 41 and the outer chain 42 run synchronously, they can carry the mesh belt to move to one side in a separated and open state, so that the bottom can be opened as much as possible without blocking the wind and reducing wind resistance. When the chain moves to the first guide wheel 23, the chain plate fixing frame 5 on the inner chain 41 enters the engagement position and merges with the chain plate fixing frame 5 of the previous outer chain 42 to form a whole and continue to move forward. At the same time, the next outer chain 42 also comes to the bottom of the second guide wheel 24 and enters the preparation stage for merging. Until it moves to the top of the first guide wheel 23, it will cooperate with the chain plate fixing frame 5 on the next inner chain 41 to reset.

[0029] In another embodiment, the chain can move clockwise as well as counterclockwise, with the opposite direction of movement and the opposite action. Specifically, the mesh belt opens at the first guide wheel 23, separates at the second guide wheel 24, and rejoins at the fourth guide wheel 26. The clockwise movement is that the mesh belt either opens at the fourth guide wheel 26, separates at the third guide wheel 25, and rejoins at the first guide wheel 23.

[0030] In another embodiment, in order to cooperate with the gear train and chain guidance layering in the above embodiment, the driven wheel 21, the driving wheel 22, the first guide wheel 23, and the fourth guide wheel 26 are coaxial double wheel structures.

[0031] In another embodiment, in order for the mesh belt to connect two chains simultaneously so that they are both on the same plane at the top and can open and separate at the bottom, the mesh belt is opened and reassembled by a chain splitter 8. The chain plate fixing frame 5 is set on the chain splitter 8, and the mesh belt is set as a multi-segment mesh belt. Specifically, the chain splitter 8 is set as a layered frame that stacks the chain plate fixing frames 5 in layers, so that the chain plate fixing frames 5 can separate with the layered movement of the chain and reassemble at the top.

[0032] In another embodiment, to facilitate the cooperation between the mesh belt and the chain, the mesh belt is made of stainless steel woven mesh or perforated mesh. A specific option is that the stainless steel woven mesh is made of stainless steel mesh chain, which has both a certain supporting strength and a certain tensile strength, and facilitates connection and movement.

[0033] In this device, the mesh belt is opened and closed by the chain splitter 8, and the chain plate fixing frame 5 is set on the chain splitter 8, specifically, as follows: Figure 3 and Figure 5As shown, the chain splitter includes an inner chain 41 and an outer chain 42. A third connecting plate 83 is connected to the outer chain plate of the inner chain 41, and a first connecting plate 81 is connected to the outer chain plate of the outer chain 42. A second connecting plate 82 is connected to the first connecting plate 81. The first connecting plate 81 spans over the inner chain 41, so that the second connecting plate 82 and the third connecting plate 83 are positioned opposite each other. A chain plate locking plate 87 is provided on the second connecting plate 82, and another chain plate locking plate 87 is provided on the third connecting plate 83. The two chain plate locking plates 87 are positioned in close contact with each other. In fact, the chain plate fixing frame 5 has been integrated into this device in the chain splitter. The chain plate locking plate 87 is used to fix the mesh belt. In this device, the key is that the first connecting plate 81 crosses over the inner chain 41, and the second connecting plate 82 and the third connecting plate 83 are set opposite each other. This ensures that the two chains can run normally without affecting each other, and that the chain plate locking plates 87 on the second connecting plate 82 and the third connecting plate 83 can both fit together and separate. This is because if the first connecting plate 81 does not cross the inner chain 41, the two chains cannot be on the same plane, resulting in an uneven mesh belt that cannot transport materials normally. If the second connecting plate 82 and the third connecting plate 83 are not set opposite each other, the two chain plate locking plates 87 cannot fit together smoothly unless other connecting parts are used to eliminate the misalignment. When they need to be separated to separate the mesh belt, the movement is restricted due to the misalignment and the addition of other parts, making it impossible to separate the mesh belt normally. Furthermore, the two chain plate interlocking plates 87 must be fitted together to prevent gaps in the connecting mesh belts; otherwise, gaps would cause material to fall, increasing conveying difficulty. Therefore, this device uses a first connecting plate 81 spanning over the inner chain 41, with the second connecting plate 82 and the third connecting plate 83 facing each other. This allows the mesh belt to connect to two chains simultaneously, ensuring they are on the same plane at the top and can also open and separate at the bottom. Ultimately, this double-chain mesh belt allows for better layering and vertical separation at the lower level of transport without affecting normal conveying, resulting in reduced wind resistance and greater ventilation.

[0034] In another embodiment, the double-chain conveyor belt is guided by the sprocket system 2, causing the mesh belt to stand upright. The two chains are layered through the double-chain configuration and the drive of the sprocket system 2. Therefore, the chains rotate during transport guided by the guide wheels. To facilitate movement and prevent jamming, as shown... Figure 5 As shown, one end of the first connecting plate 81 is fixedly mounted on the top of the outer chain plate of the outer chain 42, and the second connecting plate 82 is rotatably mounted on the first connecting plate 81 via a rotating shaft; the third connecting plate 83 is rotatably mounted on the inner chain 41 via a rotating shaft. In this way, during operation, as the guide wheel rotates, the connection point of the mesh belt can also rotate adaptively, thereby avoiding jamming.

[0035] In another embodiment, in order for the two chain plate snap-fit ​​plates 87 to fit well at the top, such as Figure 3 As shown, the rotation centers of the third connecting plate 83 and the second connecting plate 82 are located on the same axis. This ensures that the two chain plate engaging plates 87 are aligned on a single plane when they are in contact.

[0036] In another embodiment, to facilitate the connection of other components and make the chain plate snap-fit ​​plate 87 easier to position, fit, and rotate, such as... Figure 3 Figure 5 and Figure 6 As shown, the first connecting plate 81 is L-shaped, the second connecting plate 82 is L-shaped, and the third connecting plate 83 is L-shaped. The connecting plates 87 of the second connecting plate 82 and the third connecting plate 83 each occupy half of the rotation axis and can fit together. In this way, when the conveyor belt rotates to the top, it is pulled and rotated by the connecting plates 87 at the front and rear, and the notches of the second connecting plate 82 and the third connecting plate 83 fit together and are positioned. The structure is simple and practical, and it facilitates its movement.

[0037] In another embodiment, for easy replacement or installation adjustment, the two chain plate snap-fit ​​plates 87 are respectively fastened to the second connecting plate 82 and the third connecting plate 83 by screws.

[0038] In another embodiment, to ensure a good fit between the two chain plate locking plates 87 at the sprocket rotation point, preventing material leakage or jamming, a lower chain plate frame 84 and an upper chain plate frame 85 are provided at the joint of the two chain plate locking plates 87. The lower chain plate frame 84 and the upper chain plate frame 85 fit together, and a nested hinge connection rotation structure 86 is provided at the joint of the lower chain plate frame 84 and the upper chain plate frame 85. The hinge connection rotation center does not have a rotation shaft. In this way, the hinge connection rotation structure 86 ensures that the conveyor belt remains tightly fitted without gaps at the sprocket rotation point, facilitates the opening of the two chain plate locking plates 87, and allows for easy adjustment of the connection position and gap during installation according to actual conditions.

[0039] In another embodiment, due to the provision of the chain plate frame, the positions of the two chain plate snap-fit ​​plates 87 change, requiring the chain plate frame to be repositioned. In this embodiment, the nesting center of the hinge connecting rotating structure 86 is set on the rotation center axis located between the third connecting plate 83 and the second connecting plate 82.

[0040] In another embodiment, for ease of installation, transverse connecting screw holes 88 for fastening are provided on the second connecting plate 82 and the third connecting plate 83.

[0041] In another embodiment, during actual use, personnel may work on the conveyor belt; therefore, the conveyor belt needs a certain level of support strength, such as... Figure 4 As shown, the device sets the lower chain plate frame 84 and the upper chain plate frame 85 in an L-shape, with two chain plate locking plates 87 set on the inner side. In addition, an auxiliary shaft 6 is also set on the chain on the inner side. In this way, the lateral bending resistance is enhanced by the L-shaped chain plate frame, the chain plate locking plates 87 and the auxiliary shaft 6, thereby improving the support strength.

[0042] In another embodiment, such as Figure 5 As shown, in order to facilitate the installation and adjustment of the first connecting plate, a connecting plate is vertically installed on the top of the outer chain plate of the outer chain 42. The first connecting plate 81 is connected to the vertical connecting plate on the outer chain plate of the outer chain 42 by screws.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
