Description

Technical Field

[0001] The utility model belongs to the technical field of material conveying, in particular to a corner material conveying device. Background Art

[0002] Conveyor belts, also known as conveyor belts, are composite products of rubber, fiber, metal, or plastic and fabric used in belt conveyors to carry and transport materials. Conveyor belts are widely used in cement, coking, metallurgy, chemical, steel, food and other industries where the conveying distance is short and the conveying volume is small.

[0003] Conveyor belt devices are essential automation equipment in modern production lines. Usually, due to the different layout positions of production and processing equipment in the production line, conveyor belt devices are needed to complete the transmission. For transmission belts that need to change the direction of material transmission, the commonly used method is to directly connect two conveyor belts vertically, that is, the angle between the two transmission belts is 90 degrees, so as to change the direction of material transmission and achieve the purpose of corner transmission.

[0004] When bagged materials (such as bagged meal) are conveyed on two vertically connected conveyor belts, the bagged materials may contact the two conveyor belts at the same time during the transfer from the first conveyor belt to the second conveyor belt. The two conveyor belts will generate mutual forces through the bagged materials, and the forces are perpendicular to their respective running directions. In particular, due to the inertia of the bagged materials on the first conveyor belt, a greater push is exerted on the second conveyor belt (perpendicular to the running direction of the second conveyor belt), and the second conveyor belt is prone to deviation, which can easily cause wear and reduce the service life of the second conveyor belt. Utility Model Content

[0005] In order to solve the problem that when bagged materials are conveyed on two vertically connected conveyor belts, the inertia of the bagged materials on the first conveyor belt will exert a greater push on the second conveyor belt, causing the second conveyor belt to be easily offset, which can easily cause wear and reduce the service life of the second conveyor belt, the utility model provides a corner material conveying device.

[0006] The utility model is realized by the following technical solutions:

[0007] A corner material conveying device comprises a first conveyor belt device and a second conveyor belt device which are vertically connected; the first conveyor belt device comprises a first frame, a first head roller and a first tail roller which are rotatably mounted at the front and rear ends of the first frame, a first conveyor belt is wrapped around the first head roller and the first tail roller, and a plurality of first support rollers which are rotatably mounted on the first frame at intervals in front and back for providing rolling support for the belt on the first conveyor belt; the second conveyor belt device comprises a second frame, a second head roller and a second tail roller which are rotatably mounted at the front and rear ends of the second frame, a second conveyor belt is wrapped around the second head roller and the second tail roller, and a plurality of second support rollers which are rotatably mounted on the first frame at intervals in front and back for providing rolling support for the belt on the second conveyor belt; the first tail roller is arranged on the upper side of the front part of the second conveyor belt, the second support roller corresponding to the first tail roller is a second bearing roller, and a plurality of second bearing rollers are closely arranged; the surface of the second bearing roller is an arcuate surface with a raised middle part, and the edges at both ends thereof are provided with stop protrusions which can limit the edges of the second conveyor belt.

[0008] A further improvement of the utility model is that a raised second transmission belt middle rib is provided at the middle of the inner side of the second conveyor belt, and a second bearing roller middle groove is provided at the middle of the outer ring of the second bearing roller, which can engage and limit the second transmission belt middle rib.

[0009] A further improvement of the utility model is that the inner edges of the second conveyor belt are provided with raised second conveyor belt side ribs, and the outer ring edges of the second bearing roller are provided with second bearing roller edge grooves that can engage and limit the second conveyor belt side ribs.

[0010] A further improvement of the utility model is that the cross section of the stop protrusion is semicircular.

[0011] A further improvement of the utility model is that the surface of the first tail roller is in the shape of an arc surface with a convex middle portion.

[0012] A further improvement of the utility model is that a raised first transmission belt rib is provided at the middle of the inner side of the first conveyor belt, and a first tail roller clamping groove capable of engaging and limiting the first transmission belt rib is provided at the middle of the outer ring of the first tail roller.

[0013] A further improvement of the utility model is that the lower sides of the first frame and the second frame are respectively provided with tensioning devices capable of tightening the first conveyor belt and the second conveyor belt, and the tensioning devices include tensioning wheels.

[0014] It can be seen from the above technical solutions that the beneficial effects of the utility model are:

DETAILED DESCRIPTION

[0023] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0024] like Figure 1-5 As shown, an optional embodiment of the utility model discloses a corner material conveying device, including a first conveyor belt device 1 and a second conveyor belt device 2 which are vertically connected; the first conveyor belt device 1 includes a first frame 11, a first roller 14 and a first tail roller 13 which are rotatably mounted at the front and rear ends of the first frame 11, a first conveyor belt 12 is surrounded by the first roller 14 and the first tail roller 13, and a plurality of first support rollers 15 which are rotatably mounted on the first frame 11 at intervals in front and back to support the first conveyor belt 12 on a rolling basis; the second conveyor belt device 2 includes a second frame 21, a first roller 14 which is rotatably mounted at the front and rear ends of the second frame 21, and a first roller 15 which is rotatably mounted at the front and rear ends of the second frame 21. The second head roller 24 and the second tail roller 23 at the tail end, the second head roller 24 and the second tail roller 23 are surrounded by the second conveyor belt 22, and a plurality of second support rollers 25 for rolling support on the second conveyor belt 22 are rotatably installed on the first frame 11 at intervals in the front and rear; the first tail roller 13 is arranged on the upper side of the head of the second conveyor belt 22, and the second support roller 25 corresponding to the first tail roller 13 is the second bearing roller 26, and a plurality of second bearing rollers 26 are closely arranged; the surface of the second bearing roller 26 is an arc surface with a convex middle part, and the edges at both ends are provided with stop protrusions 263 that can limit the edge of the second conveyor belt 22.

[0025] When the bagged material is transferred from the first conveyor belt 12 to the corner of the second conveyor belt 22, due to the conveying inertia of the first conveyor belt 12, the head of the second conveyor belt 22 will have a thrust away from the first conveyor belt device 1 (to the right); the second conveyor belt 22 (the falling position of the bagged material) is rolled and supported by a plurality of second bearing rollers 26 closely arranged corresponding to the first tail roller 13, effectively ensuring the reliable support of the bagged material by the second conveyor belt 22 at this position, and the surface of the second bearing roller 26 is an arc-shaped surface with a raised middle part, which effectively increases the static friction of the second conveyor belt 22 relative to the second bearing roller 26, and the edges of both ends of the second bearing roller 26 are provided with stop protrusions 263 that can limit the edge of the second conveyor belt 22, effectively avoiding the wear and life reduction caused by the force offset of the feeding position of the second conveyor belt 22. The overall structure is simple, easy to implement, and practical.

[0026] Among them, Figure 4As shown, a raised second transmission belt middle rib 221 is provided at the middle of the inner side of the second conveyor belt 22, and a second bearing roller middle clamping groove 261 capable of engaging and limiting the second transmission belt middle rib 221 is provided at the middle of the outer ring of the second bearing roller 26. Raised second conveyor belt side ribs 222 are provided at both edges of the inner side of the second conveyor belt 22, and second bearing roller edge clamping grooves 262 capable of engaging and limiting the second conveyor belt side rib 222 are provided at both edges of the outer ring of the second bearing roller 26. The second bearing roller edge clamping groove 262 is arranged on the inner side of the stop protrusion 263. By setting the second conveyor belt 22 with the second transmission belt middle rib 221 and the second conveyor belt side rib 222, the tensile strength of the second conveyor belt 22 is effectively increased and the service life is improved; and by engaging the ribs of the second conveyor belt 22 (the second transmission belt middle rib 221, the second conveyor belt side rib 222) with the slots on the second bearing roller 26 (the second bearing roller middle slot 261, the second bearing roller edge slot 262), the positioning of the second conveyor belt 22 is improved to avoid the problem of force deviation of the second conveyor belt 22.

[0027] Furthermore, the second head roller 24 and the second tail roller 23 are provided with corresponding slots corresponding to the second transmission belt middle rib 221 and the second conveyor belt side rib 222 to ensure reliable stability of the overall operation of the second conveyor belt device 2.

[0028] The cross section of the stop protrusion 263 is semicircular, which effectively avoids the problem of the bagged material being scratched by the stop protrusion 263 .

[0029] Among them, Figure 4 As shown, the surface of the first tail roller 13 is in the shape of an arc with a convex middle portion, which increases the static friction between the first tail roller 13 and the first conveyor belt 12, prevents the first conveyor belt 12 from being offset and worn at the first tail roller 13, and ensures the service life of the first conveyor belt 12.

[0030] Furthermore, a raised first transmission belt rib 121 is provided in the middle of the inner side of the first conveyor belt 12, and a first tail roller clamping groove 131 capable of clamping and limiting the first transmission belt rib 121 is provided in the middle of the outer ring of the first tail roller 13. The first tail roller clamping groove 131 is used to clamp and limit the first transmission belt rib 121, thereby effectively preventing the first conveyor belt 12 from being offset and worn at the first tail roller 13.

[0031] The first frame 11 and the second frame 21 are provided with a tensioning device 3 on the lower side thereof, which can tighten the first conveyor belt 12 and the second conveyor belt 22. The tensioning device 3 includes a tensioning wheel, which is rotatably mounted on a connecting rod, which is rotatably mounted on the frame, and an elastic support mechanism rotatably connected to the connecting rod is rotatably mounted on the frame. The elastic support mechanism can be a spring, a cylinder, etc., to achieve continuous tensioning of the conveyor belt, ensure the stable and reliable operation of the conveyor belt, and avoid slipping.

[0032] The first frame 11 is provided with a first power mechanism for rotating the first tail roller 13, and the second frame 21 is provided with a second power mechanism for rotating the second tail roller 23. The tail roller is an active roller, which ensures the tightness of the conveyor belt and the stability of material transportation.

[0033] This corner material conveying device rolls and supports the second conveyor belt 22 (the falling position of bagged materials) through a plurality of second bearing rollers 26 closely arranged corresponding to the first tail roller 13, effectively ensuring the reliable support of the bagged materials by the second conveyor belt 22 at this position, and the surface of the second bearing roller 26 is an arc-shaped surface with a raised middle part, which effectively increases the static friction of the second conveyor belt 22 relative to the second bearing roller 26, and the edges of both ends of the second bearing roller 26 are provided with stop protrusions 263 that can limit the edge of the second conveyor belt 22, effectively avoiding the wear and life reduction caused by the force deviation of the feeding position of the second conveyor belt 22.
