Description

Technical Field

[0001] The utility model relates to the technical field of vegetable processing, and particularly relates to a belt conveyor which is convenient for disassembly and maintenance. Background Art

[0002] Nowadays in the food processing industry, it has become a mainstream trend to replace manual labor with machinery. In the process of processing some food vegetables, there is a step of screening and feeding in the processing of vegetable raw materials. Therefore, a large number of vegetables need to be placed on the conveyor belt. When pouring the vegetables onto the conveyor belt, the sediment on the vegetables will fall into the machine frame. After the sediment accumulates to a certain amount, it will have a certain impact on the operation of the conveyor. At the same time, the conveyor belt is prone to fatigue after long-term work and is easy to slacken. The sediment on the vegetables is more likely to enter the machine frame from the gaps in the belt, affecting the transmission effect. Content of the Utility Model

[0003] In order to solve the problems of the above-mentioned prior art, the utility model adopts a belt conveyor which is convenient for disassembly and maintenance, can adjust the tightness of the belt, solves the problem that it is not easy to clean the sediment after it enters the machine frame, and at the same time solves the problem that the conveyor belt is easy to slacken after long-term work.

[0004] To achieve the above object, the utility model provides the following technical solution: A belt conveyor which is convenient for disassembly and maintenance, including a machine frame and a conveyor belt sleeved on the machine frame. A first rotating shaft is arranged at the rear end of the machine frame, and a driving roller is sleeved on the first rotating shaft. One end of the first rotating shaft is connected to the output end of a driving motor. The front end of the machine frame is connected with an adjusting frame by bolts. A chute is horizontally opened on the side surface of the adjusting frame, and a second rotating shaft is slidably connected in the chute. A driven roller is sleeved on the second rotating shaft. A tensioning mechanism for adjusting the tightness of the conveyor belt is installed on the side wall of the adjusting frame.

[0005] Preferably, the tensioning mechanism includes a first rotating cylinder rotatably connected to one end of the second rotating shaft. The other end of the first rotating cylinder is internally threaded with an adjusting screw rod. The other end of the adjusting screw rod is threadedly connected with a second rotating cylinder. The other end of the second rotating cylinder is rotatably connected with a rotating rod, and the rotating rod is rotatably connected to the side wall of the adjusting frame.

[0006] With the above structural design, by rotating the adjusting screw rod, controlling the lengths of both ends of the adjusting screw rod extending into the first rotating cylinder and the second rotating cylinder, the second rotating shaft slides in the chute, so as to control the distance between the driving roller and the driven roller, achieving the effect of finely adjusting the tightness of the conveyor belt.

[0007] Preferably, a nut is fixedly sleeved on the middle position of the adjusting screw rod, and a stop block for restricting the displacement of the tensioning mechanism is installed at the lower end of the adjusting screw rod.

[0008] With the above structural design, the stop block is arranged at the lower end position close to the tensioning mechanism. When the conveyor is running, the adjusting screw of the tensioning mechanism is lapped on the stop block, so that the tensioning mechanism will not deform and cause the second rotating shaft to slide in the chute, ensuring the stability of the conveyor operation. When it is necessary to clean the inside of the frame and the conveyor belt, the staff needs to lift the adjusting screw to make both ends of the adjusting bolt rotate relative to the first rotating cylinder and the second rotating cylinder, so that the second rotating shaft slides to the right in the chute, thereby shortening the distance between the driving roller and the driven roller until the tension of the conveyor belt disappears, which is convenient for lifting the conveyor belt and cleaning the sediment in the frame.

[0009] Preferably, baffles are installed on both sides of the upper end of the frame along the length direction. The lower ends of the baffles are close to the conveyor belt and cover both sides of the conveyor belt. Outer guide strips are fixedly arranged along the length direction on both sides of the conveyor belt.

[0010] With the above structural design, the baffles close to the conveyor belt can effectively prevent vegetables from falling out from both sides of the belt, and the cooperation between the baffles and the outer guide strips can effectively prevent the sediment carried by the vegetables from entering the frame through the gaps on both sides of the conveyor belt, reducing the probability of device failure.

[0011] Preferably, the conveyor belt is sleeved on the driving roller and the driven roller. Convex strips are installed on the inner side surface of the conveyor belt, and grooves matching with the convex strips are formed on the driving roller and the driven roller.

[0012] With the above structural design, through the cooperation between the convex strips and the grooves, the contact area between the conveyor belt, the driving roller and the driven roller is increased, making their combination more compact, effectively avoiding the phenomenon of the conveyor belt running off track, and there is no need to install a deviation correction mechanism, simplifying the structure and cost of the conveyor.

[0013] Preferably, a protective shell is installed outside the driving motor.

[0014] With the above structural design, a protective shell is arranged outside the driving motor to prevent sundries from entering the machine interior and damaging the machine.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1. The stopper is arranged at the lower end position close to the tensioning mechanism. When the conveyor is running, the adjusting screw of the tensioning mechanism is lapped on the stopper, so that the tensioning mechanism will not be deformed to cause the second rotating shaft to slide in the chute, ensuring the stability of the conveyor operation. When it is necessary to clean the inside of the frame and the conveyor belt, the staff needs to lift the adjusting screw, so that both ends of the adjusting bolt rotate relative to the first rotating cylinder and the second rotating cylinder, and the second rotating shaft slides to the right in the chute, thereby shortening the distance between the driving roller and the driven roller until the tension of the conveyor belt disappears, which is convenient for lifting the conveyor belt and cleaning the sediment in the frame.

[0017] 2. By rotating the adjusting screw, the lengths of both ends of the adjusting screw extending into the first rotating cylinder and the second rotating cylinder are controlled, so that the second rotating shaft slides in the chute, thereby controlling the distance between the driving roller and the driven roller, achieving the effect of fine-tuning the tightness of the conveyor belt.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figure 1-7, the present utility model provides a technical solution: a belt conveyor facilitating disassembly and maintenance, including a frame 1 and a conveyor belt 2 sleeved on the frame 1. A first rotating shaft 4 is arranged at the rear end of the frame 1, and a driving roller 5 is sleeved on the first rotating shaft 4. One end of the first rotating shaft 4 is connected to the output end of a driving motor 3. The front end of the frame 1 is connected by bolts with an adjusting frame 7. A chute 9 is horizontally opened on the side surface of the adjusting frame 7, and a second rotating shaft 10 is slidably connected in the chute 9. A driven roller 11 is sleeved on the second rotating shaft 10. A tensioning mechanism 8 for adjusting the tightness of the conveyor belt 2 is installed on the side wall of the adjusting frame 7.

[0027] The tensioning mechanism 8 includes a first rotating cylinder 83 rotatably connected to one end of the second rotating shaft 10. The other end of the first rotating cylinder 83 is internally threaded with an adjusting screw 81. The other end of the adjusting screw 81 is threaded with a second rotating cylinder 84. The other end of the second rotating cylinder 84 is rotatably connected with a rotating rod 85, and the rotating rod 85 is rotatably connected to the side wall of the adjusting frame 7. By rotating the adjusting screw 81, the lengths of both ends of the adjusting screw 81 extending into the first rotating cylinder 83 and the second rotating cylinder 84 are controlled, so that the second rotating shaft 10 slides in the chute 9, thereby controlling the distance between the driving roller 5 and the driven roller 11, achieving the effect of finely adjusting the tightness of the conveyor belt 2.

[0028] A nut 82 is fixedly sleeved on the middle position of the adjusting screw 81, and a stop block 86 for restricting the displacement of the tensioning mechanism 8 is installed at the lower end of the adjusting screw 81. The stop block 86 is arranged at a position close to the lower end of the tensioning mechanism 8. When the conveyor is running, the adjusting screw 81 of the tensioning mechanism 8 is lapped on the stop block 86, so that the tensioning mechanism 8 will not be deformed to cause the second rotating shaft 10 to slide in the chute 9, ensuring the stability of the conveyor during operation. When it is necessary to clean the inside of the frame 1 and the conveyor belt 2, the staff needs to lift the adjusting screw 81, so that both ends of the adjusting bolt 81 rotate relative to the first rotating cylinder 83 and the second rotating cylinder 84, causing the second rotating shaft 10 to slide to the right in the chute 9, thereby shortening the distance between the driving roller 5 and the driven roller 11 until the tension of the conveyor belt 2 disappears, facilitating lifting the conveyor belt 2 and cleaning the sediment inside the frame 1.

[0029] On both sides of the upper end of the frame 1 along the length direction, baffles 6 are installed. The lower ends of the baffles 6 are close to the conveyor belt 2 and cover both sides of the conveyor belt 2. Outer guide strips 13 are fixedly arranged along the length direction on both sides of the conveyor belt 2. The baffles 6 close to the conveyor belt 2 can effectively prevent vegetables from falling out from both sides of the conveyor belt 2, and the cooperation of the baffles 6 and the outer guide strips 13 can effectively prevent the sediment carried by the vegetables from entering the frame through the gaps on both sides of the conveyor belt 2, reducing the probability of device failure.

[0030] The conveyor belt 2 is sleeved on the driving roller 5 and the driven roller 11. A rib 21 is installed on the inner side surface of the conveyor belt 2, and grooves 12 matching with the rib 21 are formed on the driving roller 5 and the driven roller 11. Through the cooperation between the rib 21 and the grooves 12, the contact area between the conveyor belt 2, the driving roller 5 and the driven roller 11 is increased, making their combination tighter, effectively avoiding the phenomenon of the conveyor belt 2 running off track, and there is no need to install a deviation rectifying mechanism, thus simplifying the structure and cost of the conveyor.

[0031] A protective shell 31 is installed on the outer side of the driving motor 3. The protective shell 31 is arranged outside the driving motor 3 to prevent sundries from entering the machine interior and damaging the machine.

Although the present utility model 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 perform equivalent substitution on some of the technical features. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
