Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0037] In order to solve the above technical problems, the present application provides a belt conveying device for shortening the assembly time and improving the production efficiency.

[0038] Please refer to Figures 1-4 The belt conveying device provided by the present application comprises:

[0039] The driving mechanism 01, the driven mechanism 02, the support assembly 03 and the belt 04;

[0040] The driving mechanism 01 and the driven mechanism 02 are detachably mounted at both ends of the support assembly 03, and the belt 04 is mounted above the support assembly 03; the driving mechanism 01 is provided with a convex component 011 and a concave component 012, and the driven mechanism 02 is provided with a first roller 025 and a pressing block 023; a second roller 013 is arranged between the convex component 011 and the concave component 012, and the belt 04 is detachably mounted on the second roller 013 and the first roller 025; the convex component 011 and the concave component 012 cooperate with each other to position the second roller 013, and the pressing block 023 fixes the first roller 025.

[0041] The driving motor 014 in the driving mechanism 01 is powered to rotate, and the torque generated by the rotation of the driving motor 014 is transmitted to the second roller 013, so that the second roller 013 starts to rotate. When the second roller 013 of the driving mechanism 01 rotates under the driving of the driving motor 014, the belt 04 is driven to rotate by the friction between the belt 04 and the roller. The first roller 025 of the driven mechanism 02 rotates with the belt 04 under the action of the friction of the belt 04, so that the belt 04 is circularly driven between the driving mechanism 01 and the driven mechanism 02 to complete the transmission of the material.

[0042] The belt 04 is detachably mounted on the second roller 013 of the driving mechanism 01 and the first roller 025 of the driven mechanism 02, and the positioning of the second roller 013 by the cooperation of the convex component 011 and the concave component 012 in the driving mechanism 01 and the fixing of the first roller 025 by the pressing block 023 in the driven mechanism 02 realize the quick disassembly and assembly of the belt 04. When the belt 04 is installed, a large number of professional tools are not needed, the labor input is reduced, the installation time of the belt 04 is shortened, and the installation efficiency is improved. When the belt 04 needs to be replaced due to damage, it can be replaced flexibly. The flexibility of the structure design makes the disassembly and replacement of the belt 04 simple and easy to operate, simplifies the operation process, reduces the equipment maintenance cost, ensures the efficient and continuous operation of the logistics transportation, and further improves the operation efficiency of the entire logistics transportation system.

[0043] In an optional embodiment, the convex component 011 and the concave component 012 in the driving mechanism 01 are detachably connected by bolt connection.

[0044] In this embodiment, the convex component 011 is in a convex shape as a whole, and the shape and size of the convex part thereof are matched with the concave part of the concave component 012. The convex component 011 and the concave component 012 are both made of high-strength metal material to ensure that they can withstand the tension and torque in the transmission process of the belt 04. A plurality of bolt holes 016 are respectively arranged at the corresponding positions of the convex component 011 and the concave component 012, and the positions and sizes of the bolt holes 016 correspond to each other so as to be connected by bolts.

[0045] In the installation of the male component 011 and the female component 012, first, the male component 011 and the female component 012 are preliminarily aligned, so that the protruding part of the male component 011 is accurately embedded in the recessed part of the female component 012, while ensuring that the bolt holes 016 on the male component 011 and the female component 012 correspond one by one. Then, bolts of appropriate specifications are sequentially passed through the corresponding bolt holes 016 on the male component 011 and the female component 012, and nuts are installed on the other ends of the bolts. The nuts are tightened by a wrench or the like, so that the male component 011 and the female component 012 are tightly connected together.

[0046] In order to ensure the stability and reliability of the connection, the material of the bolts and nuts should have sufficient strength and corrosion resistance. When tightening the bolts, a certain order and torque should be followed to ensure that the stress on the male component 011 and the female component 012 in each direction is uniform. The bolt connection method can quickly and accurately connect the male component 011 and the female component 012 together without the need for complex welding or other fixing processes, greatly improving the installation efficiency.

[0047] In an optional embodiment, the male component 011 and the female component 012 of the driving mechanism 01 are provided with a wear-resistant coating on the surface to improve the wear resistance between the male component 011 and the female component 012.

[0048] In this embodiment, the wear-resistant coating selected for the surface of the male component 011 and the female component 012 is a tungsten carbide coating. Tungsten carbide has the advantages of high hardness, good wear resistance, and strong chemical stability, and can effectively resist friction and wear, prolonging the service life of the components. Specifically, the surface of the male component 011 and the female component 012 is cleaned and sandblasted. The tungsten carbide powder is placed in the powder feeder of the thermal spraying equipment, the powder feeding speed and gas flow are adjusted, and the plasma spraying equipment is used to heat the tungsten carbide powder to a molten or semi-molten state and spray it at high speed onto the surface of the male component 011 and the female component 012. After spraying is completed, the coating is heat treated to eliminate internal stress of the coating, improve the bonding strength and wear resistance of the coating.

[0049] In an optional embodiment, the driving mechanism 01 includes a driving motor 014 and a motor mounting seat 015, the driving motor 014 is mounted on the motor mounting seat 015, and the motor mounting seat 015 is fixedly connected with the male component 011 and the female component 012; the driving motor 014 is used to provide power for the driving mechanism 01 to drive the second roller 013 to rotate.

[0050] The motor mounting seat 015 is made of high-strength metal material, which has good strength and rigidity and can withstand the vibration and torque generated during the operation of the driving motor 014. The shape of the motor mounting seat 015 is designed to match the shape of the driving motor 014, and a plurality of mounting holes are provided inside. The driving motor 014 is stably mounted on the motor mounting seat 015 through bolts. The top of the motor mounting seat 015 is also provided with a positioning pin hole for precise positioning and connection with the concave assembly 012.

[0051] In this embodiment, the design of the driving mechanism 01 stably connects the driving motor 014 with the convex assembly 011 and the concave assembly 012 through the motor mounting seat 015, ensuring the stability and reliability of power transmission. The reasonable selection and installation of the driving motor 014 enable the belt 04 transmission device to operate efficiently and stably, reducing problems such as belt 04 slipping and deviation caused by unstable power transmission, and improving the working efficiency and service life of the belt 04 transmission device.

[0052] In an optional embodiment, the driven mechanism 02 further includes a driven bracket 021 and a support rod 022, and the first roller 025 is installed on the driven bracket 021 through the support rod 022, and the pressing block 023 is installed on the driven bracket 021 and fixed with the first roller 025.

[0053] The driven bracket 021 is made of high-strength aluminum alloy material and is integrally formed by die casting, which can withstand the tension and impact force generated during the operation of the belt 04. The driven bracket 021 is provided with mounting holes on both sides for connection with the side plates of the driven bracket 021. The support rod 022 is a solid steel rod with a chrome-plated surface, which has high hardness and wear resistance. The first roller 025 adopts a rubber-coated metal hub structure, and the rubber layer has good elasticity and friction, which can effectively prevent the belt 04 from slipping. The center of the roller is provided with a through hole matched with the support rod 022. One side of the pressing block 023 is provided with an arc-shaped groove matched with the first roller 025.

[0054] The support rod 022 passes through the center through hole of the first roller 025 to fix the first roller 025. Place the support rod 022 with the first roller 025 installed on the driven bracket 021, and place the pressing block 023 above the first roller 025. The support rod 022 is fixed on the driven bracket 021 through the pressing block 023, so as to limit the first roller 025.

[0055] In an optional embodiment, a groove is provided above the driven bracket 021, and a solid protrusion 027 is provided below the pressing block 023; the groove cooperates with the solid protrusion 027 below the pressing block 023 to fix the first roller 025 and limit the vertical displacement of the first roller 025.

[0056] When installing the first roller 025 in this embodiment, first install the first roller 025 on the preset position of the driven bracket 021 through the support rod 022, that is, place the first roller 025 directly above the groove. Then, slowly lower the solid protrusion 027 below the pressing block 023 to align with the groove. Subsequently, tighten the bolt through the threaded hole on the top of the pressing block 023 with the driven bracket 021. As the bolt is tightened, the pressing block 023 is pressed downward, and the solid protrusion 027 is embedded in the groove, tightly fitting the bottom and side wall of the groove, thereby effectively restricting the first roller 025 in the vertical direction and limiting the displacement of the first roller 025.

[0057] In an alternative embodiment, the driven mechanism 02 further comprises an adjusting bolt 026 and a driven bracket side plate 024; the driven bracket side plate 024 is welded on both sides of the driven bracket 021, and the screw rod of the adjusting bolt 026 abuts against the support rod 022 through the screw hole on the driven bracket side plate 024; the adjusting bolt 026 is used to adjust the position of the first roller 025 by rotating and axially moving.

[0058] When it is necessary to adjust the position of the first roller 025 in this embodiment, the operator can rotate the adjusting bolt 026 using a wrench. Since the adjusting bolt 026 is threadedly connected with the screw hole on the driven bracket side plate 024, according to the screw transmission principle, the adjusting bolt 026 will axially move when it is rotated. When the adjusting bolt 026 is rotated clockwise, the screw rod moves towards the inside of the driven bracket 021, pushing the support rod 022 and the first roller 025 to move in the corresponding direction; when the adjusting bolt 026 is rotated counterclockwise, the screw rod moves towards the outside of the driven bracket 021, and the support rod 022 and the first roller 025 will move in the opposite direction under the action of the tension of the belt 04. By accurately controlling the number of rotations and the angle of the adjusting bolt 026, the position of the first roller 025 can be finely adjusted, so that the first roller 025 is in the appropriate position, ensuring the normal operation of the belt 04.

[0059] In an alternative embodiment, the support assembly 03 comprises a friction strip 031, which is located on the inner side surface of the belt 04 and tightly fits the belt 04.

[0060] In this embodiment, when the driving mechanism 01 starts, the driving belt 04 begins to circulate. Since the friction strip 031 is located on the inner side surface of the belt 04 and tightly fits the belt 04, a friction force is generated between the friction strip 031 and the belt 04 during the operation of the belt 04. This friction force can prevent the belt 04 from slipping during operation, ensuring that the belt 04 can accurately follow the rotation of the driving mechanism 01 and move, thereby improving the efficiency and accuracy of the belt 04 transmission. On the other hand, the friction strip 031 can also guide the belt 04 to some extent, reducing the possibility of the belt 04 deviating and ensuring the stable operation of the belt 04 on the support assembly 03.

[0061] In an optional embodiment, the support assembly 03 further comprises a transverse support frame 032 and a longitudinal support frame 033, which are connected perpendicularly to each other.

[0062] In this embodiment, the transverse support frame 032 and the longitudinal support frame 033 are aligned according to the design requirements, so that the mounting holes and the connecting holes correspond one by one. High-strength bolts are inserted into the mounting holes and the connecting holes, and then nuts are used for fastening. During the fastening process, diagonal tightening is adopted to ensure that the tightening force of the bolts is evenly distributed, avoiding the occurrence of local stress concentration. In order to further enhance the reliability of the connection, spring washers can be added between the bolts and the nuts to prevent the nuts from loosening during vibration

[0063] The structural design of the transverse support frame 032 and the longitudinal support frame 033 ensures that the belt 04 does not shake and deviate during operation, improving the accuracy and efficiency of the belt 04 transmission.

[0064] In an optional embodiment, the support assembly 03 further comprises side plates 034, which are installed on the support assembly 03 and located on both sides of the belt 04.

[0065] In this embodiment, the side plates 034 are installed on the support assembly 03 and specifically located on both sides of the belt 04. The support assembly 03 comprises a transverse support frame 032 and a longitudinal support frame 033, which are connected perpendicularly to form a stable frame structure. On the longitudinal support frame 033, corresponding to the positions on both sides of the belt 04, threaded holes matching the mounting holes of the side plates 034 are pre-processed. During installation, the horizontal part of the side plate 034 is aligned with the longitudinal support frame 033, so that the mounting holes correspond one by one with the threaded holes, and then the side plate 034 is firmly fixed on the support assembly 03 using bolts.

[0066] By setting the side plates 034 on both sides of the belt 04 on the support assembly 03, the problems of belt 04 deviation and material spilling are effectively solved, improving the stability and safety of the belt 04 transmission. At the same time, the installation and replacement of the side plates 034 are simple, which is convenient for maintenance and reduces the use cost of the equipment.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the scope of the present application.
