[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-Figure 3The utility model provides a technical solution: a belt conveyor with an easy-to-replace belt, comprising a support plate 1 and a mounting plate 17, the mounting plate 17 being arranged on one side of the support plate 1, a servo motor 3 being mounted on a plate wall on a side of the support plate 1 away from the mounting plate 17 through a fixed frame, an output end of the servo motor 3 being fixedly connected to a driving shaft 4 through a coupling, the driving shaft 4 being rotatably connected to the support plate 1, and the driving shaft 4 passing through the shaft wall at one end of the support plate 1 being fixedly sleeved with a driving roller 5, a driven shaft 6 being rotatably inserted on the plate wall at the end of the support plate 1 away from the driving shaft 4, a driven roller 7 being fixedly sleeved on the shaft wall of the driven shaft 6, and the driven roller 7 and the driving roller 5 being transmission-connected through a transmission belt 15;

[0019] A travel groove 10 is formed on the wall of the support plate 1 between the driving shaft 4 and the driven shaft 6. An adjusting block 11 is slidably connected to the interior of the travel groove 10. An adjusting screw 12 is threadedly inserted into the top of one end of the adjusting block 11. The other end of the adjusting block 11 passes through the travel groove 10 and is fixedly connected to a rotating shaft 13. An adjusting roller 14 is rotatably sleeved on the shaft wall of the rotating shaft 13. The adjusting roller 14 is in contact with the inner bottom wall of the conveyor belt 15.

[0020] A plurality of connecting screw rods 16 are fixedly connected at equal intervals on the wall of the support plate 1 close to the mounting plate 17. The connecting screw rods 16 move through one end of the conveyor belt 15, pass through the mounting plate 17 and are threadedly sleeved with nuts 18.

[0021] The bottom of the support plate 1 is fixedly connected to the base plate 2, and the adjusting screw 12 passes through one end of the adjusting block 11 and is rotatably connected to the base plate 2. The base plate 2 can support the support plate 1, making the conveyor more stable and convenient to place, and the base plate 2 can support the adjusting screw 12.

[0022] The top of the adjusting screw rod 12 is fixedly connected with a rotating disk, which can make the adjusting screw rod 12 more convenient and labor-saving when rotating.

[0023] Several support shafts 8 are arranged at equal intervals between the driving shaft 4 and the driven shaft 6. The support shafts 8 are rotatably inserted into the wall of the support plate 1, and support rollers 9 are sleeved on the shaft wall of the support shaft 8. The support rollers 9 are in contact with the inner wall of the conveyor belt 15. The support rollers 9 on the support shaft 8 can support the middle position of the conveyor belt 15, which can make the load-bearing effect of the conveyor belt 15 better.

[0024] The servo motor 3 is electrically connected to the external power supply through the PLC controller. The TB6600 type PLC controller can effectively control the speed and direction of the servo motor 3, which can effectively ensure that the device can be driven normally.

[0025] Specifically, when the present invention is used, the servo motor 3 can be controlled to start by the PLC controller. When the servo motor 3 is started, the active roller 5 can be driven to rotate through the active shaft 4. When the active roller 5 rotates, the conveyor belt 15 stretched on the active roller 5 and the driven roller 7 can be driven, and the middle part of the conveyor belt 15 can be supported by the multiple supporting rollers 9.

[0026] By rotating the adjusting screw 12, the adjusting block 11 can be driven to move up and down along the travel groove 10. During the lifting process, the adjusting block 11 can adjust the height of the adjusting roller 14, thereby adjusting the tightness of the conveyor belt 15.

[0027] When the conveyor belt 15 needs to be replaced, the mounting plate 17 can be removed after the nut 18 is removed. After the mounting plate 17 is removed, the height of the adjusting roller 14 can be adjusted to loosen the conveyor belt 15, so that the conveyor belt 15 can be removed from the active roller 5 and the driven roller 7. After removal, a new conveyor belt 15 can be replaced, and finally the mounting plate 17 can be installed. After the mounting plate 17 is installed, the tightness of the conveyor belt 15 can be adjusted by adjusting the screw rod 12 to drive the adjusting roller 14.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
