Description

Technical Field

[0001] The utility model relates to a storage cabinet bottom belt chain driving structure, belonging to the technical field of tobacco storage cabinets. Background Art

[0002] The bottom belt of the storage cabinet is connected by a plate conveyor chain, and the reducer drives the active sprocket at the storage cabinet discharge end and the passive sprocket at the end of the storage cabinet to realize chain transmission. The chain is placed on the frame channel steel, and each linked roller on the chain rolls on the channel steel to reduce the friction during the chain transmission process and improve the transmission efficiency.

[0003] Since there are many materials loaded in the storage cabinet and the conveying distance is long during unloading, the channel steel is connected in multiple sections on the frame. Due to the improper design and installation of the channel steel connection or the defects in the channel steel material at the connection, the connection is uneven, which makes the roller and the roller shaft of the chain unevenly stressed before and after the connection, causing wear. After long-term operation, the wear increases, causing the conveying chain of the storage cabinet to make abnormal noises during unloading, or the chain roller is in contact with the channel steel for a long time, so that the severely worn roller no longer rotates but slides on the channel steel, reducing the transmission efficiency of the chain, increasing the load of the reducer and the risk of bottom belt chain breakage. Utility Model Content

[0004] The utility model aims to provide a storage cabinet bottom belt chain driving structure to solve the problems of abnormal noise of the bottom belt chain in the storage cabinet during discharging, and the chain roller no longer rotating and sliding on the channel steel after long-term operation.

[0005] The utility model provides a cabinet bottom belt chain drive structure, comprising a chain structure and a channel steel, wherein a guide rail is fixedly arranged on the top of the channel steel, the interface position of the guide rail is staggered with the interface position of the channel steel, the guide rail is provided with a guide groove, and the chain structure is installed on the guide rail.

[0006] In the aforementioned cabinet bottom belt chain drive structure, preferably, the guide rail is made of polytetrafluoroethylene.

[0007] In the aforementioned cabinet bottom belt chain drive structure, preferably, a plurality of countersunk mounting holes are provided on the main body of the guide rail at equal intervals along the length direction, and a threaded hole opposite to the countersunk mounting hole is provided on the top of the channel steel.

[0008] In the aforementioned storage cabinet bottom belt chain drive structure, preferably, a countersunk cross bolt is installed in each of the countersunk mounting holes.

[0009] In the aforementioned chain drive structure at the bottom of the storage cabinet, preferably, the chain structure includes rollers, a rotating shaft, and chain plates. One end of each roller has a circular limiting plate. The rollers are rotatably mounted on the rotating shaft, and both ends of the rotating shaft are rotatably connected to the chain plates. The circular limiting plates are in rolling cooperation with the guide grooves.

[0010] In the aforementioned chain drive structure at the bottom of the storage cabinet, preferably, the cross-sectional shape of the channel steel is "]" shaped.

[0011] Compared with the prior art, the present utility model includes a chain structure and channel steel. A guide rail is fixedly provided on the top of the channel steel. The interface position of the guide rail is staggered from the interface position of the channel steel. The guide rail has a guide groove, and the chain structure is installed on the guide rail. The chain structure in the present utility model is installed at the bottom of the cabinet, and the bottom belt of the cabinet is installed on the chain structure. By providing a guide rail on the channel steel, the interface of the channel steel can have a smooth transition through the guide rail, effectively solving the problem of uneven height at the interface position of the channel steel, thereby making the service life of the chain structure longer and preventing problems such as deformation and abnormal noise caused by uneven wear.

[0015] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as limiting the present utility model.

[0016] Embodiments of the present utility model: As Figure 1 and Figure 2 shown, a chain drive structure at the bottom of a storage cabinet includes a chain structure 1 and channel steel 2. A guide rail 3 is fixedly provided on the top of the channel steel 2. The interface position of the guide rail 3 is staggered from the interface position of the channel steel 2. The guide rail 3 has a guide groove 4, and the chain structure 1 is installed on the guide rail 3.

[0017] Since the bottom belt at the bottom of the storage cabinet is relatively long, multiple channel steels 2 need to be spliced. During long-term use, the splicing positions of the channel steels 2 are prone to height differences, resulting in skewing when the chain structure 1 moves to the splicing positions of the channel steels 2. Therefore, in this embodiment, a guide rail 3 is provided on the top of the channel steel 2. Through the connection of the guide rail 3, the splicing positions of the channel steels 2 can be smoothly transitioned to prevent height differences at the interface positions. Similarly, the interface positions of the guide rail 3 are staggered from the structural positions of the channel steels 2, and the channel steels 2 can also prevent the problem of uneven heights at the interface positions of the guide rail 3. In this embodiment, the cross-sectional shape of the channel steel 2 is "]".

[0018] In this embodiment, the guide rail 3 is made of polytetrafluoroethylene wear-resistant material. The guide rail 3 made of this material can reduce the wear speed when the chain structure 1 operates and improve the service life of the chain structure 1.

[0019] In a specific implementation manner, a plurality of countersunk mounting holes 5 are equidistantly arranged along the length direction on the main body of the guide rail 3, and threaded holes opposite to the countersunk mounting holes 5 are provided on the top of the channel steel 2. A countersunk cross recessed bolt 6 is installed in each countersunk mounting hole 5.

[0020] The guide rail 3 is fixed on the top of the channel steel 2 through the countersunk cross recessed bolt 6. Through the setting of the countersunk mounting holes 5, the top surface of the countersunk cross recessed bolt 6 is located within the countersunk mounting holes 5, preventing the top surface of the countersunk cross recessed bolt 6 from contacting the chain structure 1 and ensuring the service life of the chain structure 1.

[0021] Furthermore, the chain structure 1 includes rollers 7, rotating shafts 8 and chain plates 9. One end of the roller 7 has a circular limiting plate 10. The roller 7 is rotatably installed on the rotating shaft 8, and both ends of the rotating shaft 8 are rotatably connected to the chain plates 9. The circular limiting plate 10 is in rolling fit with the guide groove 4.

[0022] Compared with the existing one, the chain structure 1 only has a circular limiting plate 10 arranged at one end of the rotating shaft 8. The diameter of the circular limiting plate 10 is larger than the outer diameter of the roller 7. When the roller 7 contacts the top surface of the guide rail 3, the circular limiting plate 10 contacts the bottom of the guide groove 4. Through the setting of the circular limiting plate 10, the skewing of the roller 7 can be restricted, enabling the roller 7 to roll smoothly on the guide rail 3.

[0023] The structure, features and effects of the present invention have been described in detail based on the embodiments shown in the drawings. The above is only the preferred embodiment of the present invention, but the present invention is not limited to the implementation scope shown in the drawings. Any changes made according to the concept of the present invention, or modified into equivalent embodiments with equivalent changes, still within the spirit covered by the description and drawings, should be within the protection scope of the present invention.
