[0002] Using a conveyor belt to transport products is a relatively common method of transportation. However, after a period of use, the belt will stretch due to the characteristics of its material, which will cause the conveyor belt to become loose. Conventionally, an adjustment mechanism is needed to tighten the belt. Moreover, this tensioning method is set at the end, which means that the end of the belt will be extended. For places with insufficient space, adjustment is inconvenient, resulting in the belt continuing to be used when it can be used, and then directly replacing the belt after it slips. In other words, after its adjustment component has been adjusted to the maximum stroke, it is still in a relaxed state and cannot be tightened further.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0026] Example 1: See Figure 1-4 As shown, a transmission roller installation structure includes a transmission roller 1 and two oppositely arranged vertical plates 2, the two ends of the transmission roller 1 are respectively connected to the vertical plates 2 on both sides, each of the vertical plates 2 is provided with oppositely arranged vertical strip through-slots 3, the end of the transmission roller 1 passes through the corresponding vertical strip through-slot 3 and is arranged on the outer side of the vertical plate 2, and the end of the transmission roller 1 is connected to the vertical plate 2 via a connecting component; the connecting component is installed on the outer side wall of the vertical plate 2, and the connecting component includes an adjusting block 4, an adjusting bolt 5 and a mounting frame 6 with a hollow structure; the mounting frame 6 is installed on the outer side wall of the vertical plate 2, and the vertical strip through-slot 3 is arranged directly opposite the hollow part of the mounting frame 6;

[0027] A positioning plate 7 is provided on the outer side wall of the bottom of the mounting frame 6, and the adjusting bolt 5 is screwed to the positioning plate 7;

[0028] The left and right sides of the outer wall of the mounting frame 6 are respectively provided with guide parts 8, the adjusting block 4 is slidably connected to the guide parts 8 on both sides, and one end of the adjusting bolt 5 is rotatably connected to the adjusting block 4;

[0029] Both ends of the transmission roller 1 pass through the vertical strip-shaped through slot 3 and are rotatably connected to the adjustment blocks 4 on both sides.

[0030] Among them, the two ends of the conveyor belt are wound around the main drive roller and the auxiliary drive roller, and the transmission of the conveyor belt is realized by using a motor to drive the rotation of the main drive roller. A movable and adjustable mechanism is set at the auxiliary drive roller to adjust the tension of the conveyor belt so that the conveyor belt is always in a tensioned state. The drive roller is set between the main drive roller and the auxiliary drive roller. In the existing technology, the two ends of the drive roller are rotatably connected to the vertical plate. In this way, the drive roller only plays the role of transmission support for the conveyor belt. In this embodiment, in order to compensate for the situation where the tension adjustment stroke of the auxiliary transmission roller is insufficient, or the length of the conveying surface at the top of the conveyor belt cannot be adjusted (for example, there are conveyor belts at both ends of the conveyor belt and they cannot be moved toward the ends), vertical strip grooves can be directly opened on the vertical plates on both sides, and then connecting components are installed on the outer walls of the vertical plates at the corresponding vertical strip grooves. The transmission roller and the adjustment block in the connecting component are rotatably connected, and the adjustment block is slidably connected to the guide portion on the installation frame. Then, the position of the adjustment block is adjusted by rotating the adjustment bolt, and the transmission roller is used to tension the conveyor belt so that the conveyor belt does not loosen and remains in a tensioned state. At the same time, in this way, the original conveyor line can be quickly modified directly, or adjustable transmission rollers can be directly installed without redesigning or replacing the original conveyor line, thereby reducing costs.

[0031] In this embodiment, the mounting frame is a hollow structure, wherein the center thereof has a cavity communicating with the inside and the outside, and the vertical strip-shaped through groove is arranged opposite to the cavity.

[0032] See also Figure 2 、 3 As shown, the guide portion 8 includes a longitudinal plate 9 and a transverse plate 10 that are perpendicular to each other. The inner end of the longitudinal plate 9 is vertically connected to the outer side wall of the mounting frame 6, one end of the transverse plate 10 is vertically connected to the middle of the longitudinal plate 9, and the other end of the transverse plate 10 is arranged toward the adjustment block 4.

[0033] A sliding groove 11 is provided on the left and right sides of the adjusting block 4 , respectively. The sliding grooves 11 on both sides of the adjusting block 4 are slidably connected to the horizontal plates 10 of the guide parts 8 on both sides.

[0034] In this embodiment, the guide portion comprises a T-shaped structure formed by longitudinal and transverse plates. The adjustment block is directly slidably connected to the guide portion via a slide slot. The guide portion restricts the forward and backward movement of the adjustment block, and the vertical position of the adjustment block relative to the guide portion, and thus the position of the drive roller, can only be adjusted by rotating the adjustment bolt. Furthermore, the T-shaped guide portion facilitates easy and quick installation and removal of the adjustment block, facilitating installation, removal, and maintenance of the adjustment block.

[0035] See also Figure 1-3 As shown, the bottom of the transverse plate 10 is connected to the positioning plate 7 via a reinforcing plate 12. In order to increase the strength of the guide portion and prevent deformation of the guide portion, a reinforcing plate is provided. The transverse plate is connected to the positioning plate via the reinforcing plate, which can increase the strength of the guide portion and the positioning plate, thereby preventing deformation of the transverse plate and the positioning plate.

[0036] See also Figure 1-3 As shown, the top of the adjusting bolt 5 is arranged between the guide parts 8 on both sides, and a limiting nut 13 is screwed on the adjusting bolt 5, and the top surface of the limiting nut 13 is against the bottom surface of the positioning plate 7.

[0037] In this embodiment, in order to ensure that after the adjusting bolt rotates to move the position of the adjusting block, the adjusting block will not rotate due to the transmission force or vibration of the conveyor belt on the drive roller, thus, a limit nut is provided to limit the adjusting bolt after the position adjustment is completed. Among them, the conveyor belt will pass around the bottom outer surface of the drive roller, exerting an upward force on the drive roller. Therefore, the limit nut is provided below the positioning plate to prevent the adjusting bolt from rotating and moving upward (if the adjusting bolt rotates and moves downward, it will further tighten the belt, or the belt itself will exert tension on the drive roller, making it impossible for the adjusting bolt to rotate and drive the drive roller downward under normal circumstances). If the conveyor belt passes over the top of the drive roller, exerting downward pressure on the drive roller, the limit nut will be provided above the positioning plate to prevent the adjusting bolt from moving downward.

[0038] See also Figure 3 、 4 As shown, the adjusting block 4 is provided with a through slot 14, and the through slot 14 is arranged below the driving roller 1. A through hole 15 is provided on the bottom surface of the adjusting block 4 and communicates with the through slot 14. A bolt connector 16 is provided in the through slot 14, and the top of the adjusting bolt 5 is connected to the bolt connector 16.

[0039] A clearance hole 17 is provided on the bottom surface of the bolt connector 16 and faces the through hole 15 , and a mounting hole 18 is provided on the outer surface of the bolt connector 16 and communicates with the clearance hole 17 ;

[0040] A locking screw hole 19 matching the mounting hole is provided on the top outer edge surface of the adjusting bolt 5. The adjusting bolt 5 passes through the through hole and is inserted into the clearance hole. A locking bolt 20 is inserted into the mounting hole 18. The end of the locking bolt 20 is screwed to the locking screw hole 19. Of course, the mounting hole can also be a screw hole, and the locking bolt, the mounting hole and the locking screw hole are screwed.

[0041] The bolt connector is directly arranged in the through groove, and the top of the adjusting bolt passes through the through hole and is inserted into the makeshift hole, and then the locking bolt is used to connect and fix the bolt connector to the adjusting bolt, thereby realizing the connection and fixation of the adjusting bolt and the bolt connector. In this way, it is convenient to connect and disassemble the adjusting bolt and the adjusting block, and it is convenient to disassemble, repair and replace both.

[0042] See also Figure 1-3 As shown, the bottom of the adjusting bolt 5 is arranged below the positioning plate 7, and the bottom of the adjusting bolt is provided with a regular polyhedron structure. The regular polyhedron structure facilitates the use of tools such as a wrench to drive the adjusting bolt to rotate, thereby adjusting the position of the adjusting block.

[0043] The mounting frame is locked and positioned on the vertical plate by bolts, which makes it easy to connect or disassemble the mounting frame and the vertical plate, and to install connecting components on the vertical plate.
