Description

a belt conveyor system

technical field

The utility model relates to the technical field of belt conveying on a rubber production line, in particular to a belt conveying system.

Background technique

The belt conveyor system is a belt assembly line mainly composed of conveyor belts, driving devices, drive rollers, etc. It is a conveyor system that uses continuous motion and deflecting conveyor belts to transport materials. Carries two functions. The drive roller drives the conveyor belt to move by friction. The entire length of the conveyor belt is supported by many rollers.

Belt transportation system is mainly used in rubber machinery industry and rubber production line. On some belt conveyors in these industries, the length of the belt will change with the rotation of the rotating arm. According to the different rotation angles, the length of the production line is different, and the length of the belt is also different. When the length of the belt changes When the amount is large, the belt will be strained and the service life of the belt will be shortened. If the belt is reserved too much, the belt will be in a slack state, and the belt and the roller will directly slip. The above two situations will directly cause economic losses and bring great problems to the production line.

detailed description

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model will be further described. It should be noted here that the descriptions of these implementations are used to help understand the utility model, but are not intended to limit the utility model. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute conflicts with each other.

With reference to Fig. 1, Fig. 2, belt transportation system, comprises the frame 1 that is used to carry belt 13, and described frame 1 is provided with leg 2, and crossbeam 3 is provided between described leg 2, and described frame 1 one end is provided with There is a swing arm 4, a belt 13 is wound on the swing arm 4, the swing arm 4 is hinged with the frame 1, and the swing arm 4 is driven to swing by the cylinder 5 arranged on the crossbeam 3. The swing arm 4 is provided with a motor 14 for driving the belt 13 to move. The other end of the frame 1 is provided with a first driven roller 6 for the belt to bypass, and the connection between the frame 1 and the swing arm 4 is provided with a second driven roller 7 cooperating with the first driven roller 6, The beam 3 is provided with an automatic belt tensioning device 8 spanning between the beam 3 and the frame 1 , and the belt 13 bypasses the automatic belt tensioning device 8 .

Referring to Fig. 3, the belt automatic tensioning device 8 includes two tensioning seats 81 and a roller 82 spanning between the tensioning seats, the rollers 82 and the frame 1 are perpendicular to each other, and the rollers A retaining ring 86 is provided at the joint between the barrel 82 and the tension seat 81 . The tension seat 81 is provided with a screw rod 83 , and the two ends of the screw rod 83 are fixed on the tension seat 81 by nuts 84 . The upper section of the screw 83 is covered with a spring 85 , one end of the spring 85 is connected to the roller 82 , and the other end is connected to the tension seat 81 .

The first rollers 9, 10 for the belt 13 to bypass are arranged on both sides of the automatic belt tensioning device 8 on the frame 1, and the side where the frame 1 is connected to the swing arm 4 is provided with a The second idler roller 11 that the belt 13 bypasses, and the swing arm 4 is provided with a third idler roller 12 that the belt 13 bypasses.

The working principle of the present utility model is: the motor 14 above the swing arm 4 drives the belt 13 to move and then drives the roller 82 to rotate. When the cylinder 5 was stretched, the swing arm 4 was in a position parallel to the frame 1, as shown in Figure 1, when the cylinder 5 contracted, the swing arm was in a state perpendicular to the frame 1. During the process of the swing arm 4 changing from a position parallel to the frame 1 to a state perpendicular to the frame 1, the actual length of the belt 13 becomes longer. If there is no extra belt supply, the belt 13 itself will be elongated. Thereby strain belt 13, reduce the service life of belt. In the present utility model, the belt that needs to be supplied can be obtained from the automatic belt tensioner 8 inside. When belt 13 elongated, the tension force of belt 13 can make the roller 82 in the belt automatic tensioner 8 move upwards, when the tension force of belt 13 and the gravity of roller 82 self and spring 85 elastic force reached a dynamic equilibrium state, Roller 82 stops rising. The length of belt 13 can become longer in the process that roller 82 rises, thereby provides the belt needed in this process that swing arm 4 changes to the state perpendicular to frame 1 by the position parallel with frame 1. In the same way, when the swing arm 4 changes from the position perpendicular to the frame 1 to the process of being parallel to the frame 1, the required belt 13 will become shorter, and at this moment an excess part of the belt will come out. Make the tension force of belt 13 reduce, belt is many, can cause belt to slip. When the tension force of belt 13 decreased, the weight of roller 82 in the automatic belt tensioner 8 and the elastic force of spring 85 would be greater than the tension force of belt 13, and at this moment roller 82 would move down. When the roller 82 moved downwards to a certain position, the gravity of the roller 82 itself and the elastic force of the spring 85 would maintain a dynamic balance with the tension force of the belt 13, and the process of the downward movement of the roller 82 was a process for absorbing excess belt process. Go round and begin again like this, the tension force of belt 13 and the gravity of roller 82 self, the elastic force of spring 85 are in dynamic equilibrium state forever, thereby reach protection belt, make belt service life not reduce.

Therefore, the belt transport system of the present utility model is owing to be provided with the belt automatic tensioner 8 that spans between the beam and the frame, the belt automatic tensioner 8 relies on the gravity of the roller 82 itself, the elastic force of the spring 85 and the tension of the belt 13. The tension is in a state of dynamic balance, thereby preventing the belt 13 from being too loose and slipping or being too tight to strain the belt 13 during the conveying process, which plays a good role in protecting the belt 13, thereby improving the service life of the belt. Moreover, the cost of the belt transport system is relatively low, the tension of the belt automatic tensioning device is constant, and the practicability is relatively strong.

The embodiments of the utility model have been described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the utility model, various changes, modifications, replacements and modifications to these embodiments still fall within the protection scope of the utility model.
