Description

Technical Field

[0001] The utility model belongs to the technical field of limiting devices, and in particular relates to a limiting device for a belt conveyor. Background Art

[0002] At present, the leaf threshing and redrying industry basically uses belt conveyors as equipment for continuously transporting tobacco materials on the production line. Once the belt conveyor deviates and rubs against the edge, especially when the leaf laying belt conveyor is manually laying leaves, it is difficult to achieve consistent weight of tobacco leaves on both sides of the belt, the center of gravity of the material is unstable, and the conveyor belt deviates frequently. It is very difficult to adjust the deviation. If the operator and maintenance personnel fail to discover and adjust in time, the belt deviation and long-term friction between the side plates, bearing fixing bolts and other parts will easily cause burrs, breakage, or even falling off. The damaged parts will fall into tobacco leaves and are not discovered for a long time, which will cause major quality accidents. Rework and tracing are very difficult, and the cost of replacing the damaged belt is high.

[0003] In order to solve the problem of burrs, breakage, and falling off of tobacco leaves on the friction side plates, bearing fixing bolts and other parts after the belt deviates, eliminate the quality risks of belt falling objects and increase the service life of the belt, a belt mechanical limit device is specially designed and manufactured. Summary of the invention

[0004] The utility model provides a limiting device for a belt conveyor, which can prevent the friction side plate, bearing fixing bolts and other parts of the belt from burring, breaking, falling off and falling into tobacco leaves after the belt deviates, eliminates the quality risk of belt falling objects, and increases the service life of the belt. The specific scheme is as follows:

[0005] A limiting device for a belt conveyor comprises mounting bases arranged on opposite sides of the conveyor, wherein a plurality of the mounting bases are arranged at intervals along the conveying direction of the conveyor, and two limiting wheels are arranged horizontally and side by side on the mounting bases, and the two sides of the belt pass through the limiting grooves of the limiting wheels, and the two limiting wheels are detachably arranged on the mounting bases through pin shafts.

[0006] Furthermore, the side plates on the upper and lower sides of the mounting base are provided with adjustment grooves, and the adjustment grooves are arranged perpendicular to the belt.

[0007] Furthermore, the pin shaft includes a pin rod and a screw, the pin rod is rotatably connected to the limiting wheel, the screw is detachably arranged on both ends of the pin rod, and the limiting wheel is fixedly arranged between the two adjustment grooves by the screws at both ends of the pin rod.

[0008] Furthermore, both ends and the middle of the conveyor are provided with mounting bases, and corresponding mounting bases are provided with limiting wheels.

[0009] Furthermore, the cross-section of the limiting wheel is an I-shaped structure, and the distance between the belt and the inner side of the limiting groove is 1.5 cm±0.1 cm.

[0010] The beneficial effects of the utility model are:

[0011] The utility model discloses a limiting device for a belt conveyor, which has a simple structure, low processing cost and stable operation. It can effectively limit the friction between the side edge of the belt and the side plate of the machine body, the bearing fixing bolts and other parts after the belt deviates to produce burrs, breakage and even falling off, thereby preventing the hidden danger of the belt falling off and falling into tobacco leaves, eliminating the hidden danger of belt falling off and increasing the service life of the belt.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] See also Figure 1-6 , a limiting device for a belt conveyor comprises a mounting base 2 arranged on opposite sides of a conveyor 1, the mounting base 2 being detachably connected to the side plate of the conveyor 1 by bolts, the mounting base 2 being arranged with several intervals along the conveying direction of the conveyor 1, and two limiting wheels 3 being arranged horizontally and side by side on the mounting base 2, the two sides of the belt pass through the limiting grooves of the limiting wheels 3, the two limiting wheels 3 being detachably arranged on the mounting base 2 by pin shafts 4, the limiting wheels 3 can be rotated by the pin shafts 4, when the belt conveyor manually lays leaves, the tobacco leaves on both sides of the belt cannot meet the weight consistency phenomenon, the center of gravity of the material is unstable and the conveying belt deviates frequently, the belt is effectively limited by the limiting grooves in the limiting wheels 3, which can prevent the belt from deviating to a limited extent, and prevent the belt from being damaged due to various edge frictions, thereby increasing the service life of the belt.

[0021] Preferably, the side plates on the upper and lower sides of the mounting base 2 are provided with adjustment grooves 5, which are arranged perpendicular to the belt. The setting of the adjustment groove 5 can reasonably adjust the position of the limiting wheel 3 in the adjustment groove 5 according to the gap between the belt and the side plate of the conveyor 1.

[0022] The preferred pin shaft 4 includes a pin rod 41 and a screw 42. The pin rod 41 is rotatably connected to the limiting wheel 3. The screw 42 is detachably arranged on both ends of the pin rod 41. The limiting wheel 3 is fixed between the two adjustment grooves 5 by the screws 42 at both ends of the pin rod 41. The combination of the pin rod 41 and the screw 42 can adjust the upper and lower positions of the limiting wheel 3 to adapt to the operation of the belt.

[0023] Preferably, both ends and the middle of the conveyor 1 are provided with mounting bases 2, and corresponding mounting bases 2 are provided with limiting wheels 3. The arrangement of several limiting wheels 3 can better lift the belt so that the belt can run better.

[0024] The preferred cross-section of the limiting wheel 3 is an I-shaped structure, and the distance between the belt and the inner side of the limiting groove is 1.5 cm ± 0.1 cm, which reduces the wear of the belt while ensuring a certain amount of activity space during the operation of the belt.
