Description

Technical Field

[0001] The invention relates to the technical field of belt conveyors, and in particular to a belt-type self-adaptive deflection-adjusting and turning belt conveyor. Background Art

[0002] In the prior art, in order to raise the inner curve, a method is adopted to achieve this by setting a spring on the inner side of the roller frame, and adjusting the strength of the spring according to the amount of transportation. The disadvantage of this technology is that the adjusted roller frame can only adapt to one amount of transportation and tensioning force. If the transportation amount or tensioning force changes, it is very easy to cause problems such as conveyor belt deviation and belt winding. In addition, in adjusting the deviation of the conveyor belt, stop rollers are basically set at both ends of the roller frame to force the conveyor belt to be blocked, which causes great damage to the conveyor belt and requires high strength of the roller frame and the stop roller. Summary of the invention

[0003] In view of the above defects, the present invention proposes an adaptive deflection turning belt conveyor, including a straight section conveyor and a bending section conveyor, the bending section conveyor includes a bending body, the bending body includes an inner frame, an outer frame, a plurality of bearing frames, a return frame, a bearing roller group, and a return roller group, the bearing frame and the return frame are fixedly arranged between the inner frame and the outer frame, the bearing frame is arranged above the return frame, and the belt includes an upward section running above the bearing roller group and a return roller group. The running down section is opposite to the running direction of the up section and the down section; the bearing frame and the return frame are both arc-shaped frames, and in the horizontal direction, the arc-shaped protruding direction of the bearing frame is opposite to the running direction of the up section of the belt, and the arc-shaped protruding direction of the return frame is opposite to the running direction of the down section of the belt; in the vertical direction, the arc-shaped directions of the bearing frame and the return frame are both bent downward; the bottom of the bearing roller group is movably connected to the bearing frame, and the bottom of the return roller group is movably connected to the return frame.

[0004] The present invention is a self-adaptive deflection turning belt conveyor, which is mainly used in situations where continuous transportation is achieved in the form of horizontal turning due to terrain restrictions or in order to reduce overlapping links. It solves the problems of conveyor belt winding and serious deviation causing conveyor belt cuts when the current turning belt conveyor turns. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] See also Figure 1-5A self-adaptive deflection turning belt conveyor, comprising a straight section conveyor and a bending section conveyor, wherein the bending section conveyor comprises a bending body, wherein the bending body comprises an inner frame 10, an outer frame 20, a plurality of bearing frames 30, a return frame 40, a bearing roller group 50, and a return roller group 60, wherein the bearing frame 30 and the return frame 40 are fixedly arranged between the inner frame 10 and the outer frame 20, the bearing frame 30 is arranged above the return frame 40, the belt comprises an upward section 70 running on the bearing roller group 50 and a downward section 80 running on the return roller group 60, the upward section 70 The running direction of the downward section 80 is opposite to that of the downward section 80; the bearing frame 30 and the return frame 40 are both arc-shaped frames. In the horizontal direction, the arc-shaped protruding direction (F bearing) of the bearing frame 30 is opposite to the running direction (F up) of the upward section 70 of the belt, and the arc-shaped protruding direction (F return) of the return frame 40 is opposite to the running direction (F down) of the downward section 80 of the belt; in the vertical direction, the arc-shaped directions of the bearing frame 30 and the return frame 40 are both bent downward; the bottom of the bearing roller group 50 is movably connected to the bearing frame 30, and the bottom of the return roller group is movably connected to the return frame 40.

[0018] like Figure 7 , 8 9. In this solution, through the arc-shaped supporting roller frame, and the inner upper roller 52 and the outer upper roller 53, the belt has a centripetal force (F centripetal force) to bend inward under the action of the driving force at the end of the belt. Based on the relative operation, the material on the upper section 70 of the belt has a centrifugal force to move outward. Due to the mass of the material itself, the friction between it and the belt and the control of the belt speed, the material will not fly outward under the action of the centrifugal force. However, due to the force of the driving roller, for example, when turning right to turn inward, the belt will inevitably bend inward under the action of the F centripetal force, thereby pulling the supporting roller frame to have the potential energy to move inward. In the original design, the supporting roller frame is fixedly connected to the frame. Under the action of the centripetal force, the belt either slides with the roller or approaches the internal stop roller. The stop roller 90 blocks the belt, so that the high-speed running belt returns to its original position, but it is easy to cause the upper section 70 of the belt to bend, squeeze, or tear. Fig.11 In this scheme, if Figure 6 When the adhesive tape is subjected to the centripetal force, the adhesive tape drives the lower part of the carrying roller frame to move inward on the carrying frame 30. Since the carrying frame 30 is arranged in an arc shape, the height of the inner side is higher than the height in the middle. The roller group moves inward and moves toward the inner side of the carrying frame 30, and is lifted by the carrying frame 30, thereby lifting the inner side of the adhesive tape. The lifted material on the raised adhesive tape on the inner side will flow to the lower part, and will give the outer side of the adhesive tape a downward and outward force, thereby offsetting the centripetal force of the adhesive tape, and prompting the roller frame to move outward along the carrying frame 30, thereby realizing the function of automatic deviation correction of the adhesive tape.

[0019] The downward curved arc-shaped support frame 30 in this solution is different from the horizontal frame. The higher arc-shaped frame on the inside provides a raised structural design for the roller group, providing potential energy for the material on the belt to move outward. At the same time, the arc-shaped protrusion directions of the support frame 30 and the return frame 40 in the horizontal direction are different. Since the running directions of the upward section and the downward section are opposite, the protrusion direction is also opposite. The purpose is to be the same as the running direction of the belt. When the belt is bent inward, the axial direction of the inner upper roller 55 of the support roller group 50 raised by the inner side of the support frame 30 presents an acute angle a with the tangent direction of the upward section of the belt at the turning point (on the F tangent line), so that the axial direction of the inner upper roller 55 also presents an acute angle a with the tangent direction of the belt. This relatively small angle reduces the resistance to the belt, prompts the belt to tilt forward, and has a corrective effect on the belt. Similarly, the return roller group 60 raised on the inner side of the return frame 40 also forms an acute angle a with the tangent direction of the belt down section at the turning point (on the F tangent line), which plays a role in correcting deviation. It can be seen that the arc-shaped protrusion directions of the carrying frame 30 and the return frame 40 are different, which are set respectively for the different running directions of the up section and the down section, and both have the function of correcting deviation.

[0020] like Fig.10 If the arc-shaped protrusion direction of the carrying frame 30 and the return frame 40 in the horizontal direction is the same as the running direction of the belt, when turning on the inside, as shown in the figure, the axial direction of the inner upper roller 55 of the carrying roller group 50 raised by the inner side of the carrying frame 30 and the tangent direction of the belt at the turning point will form an obtuse angle b, so that the axial direction of the inner upper roller 55 and the tangent direction of the belt also form an obtuse angle b. This relatively large angle will increase the resistance to the belt, which will not only have no effect on correcting the deviation, but will also aggravate the degree of belt deviation.

[0021] When the return roller group turns on the inner side, the working principle is the same as that of the load-bearing roller group 50, and will not be repeated.

[0022] Furthermore, the load-bearing roller group 50 includes an upper roller frame 51, an inner upper roller 52, an outer upper roller 53, an intermediate roller 54, an inner upper roller 55, and an outer upper roller 56. The intermediate roller 54, the inner roller, and the outer roller are arranged on the upper roller frame 51, and the inner upper roller 52 and the outer upper roller 53 are arranged at the bottom of the upper roller frame 51, and are respectively on the inner and outer sides of the upper roller frame 51. The inner roller and the outer roller are rollingly connected to the load-bearing frame 30 so that the inner upper roller 52 and the outer upper roller 53 can move left and right on the load-bearing frame 30.

[0023] Furthermore, annular grooves along the circumferential direction are provided on the middle roller 54, the inner upper roller 55, and the outer upper roller 56. This increases the friction force when the belt moves axially inward on the roller, and when turning inward, the greater friction force causes the belt to drive the roller and the roller frame to move inward, thereby causing the inner belt to be lifted, thereby overcoming the belt deviation.

[0024] Furthermore, the return roller group includes a lower roller frame 61, an inner lower roller 62, an outer lower roller 63, an inner lower roller 64, and an outer lower roller 65. The inner lower roller 64 and the outer lower roller 65 are arranged on the lower roller frame 61, the inner lower roller 62 and the outer lower roller 63 are arranged at the bottom of the lower roller frame 61, and are respectively on the inner and outer sides of the lower roller frame 61. The inner lower roller 62 and the outer lower roller 63 are rollingly connected to the supporting frame 30 so that the rollers can move left and right on the supporting frame 30.

[0025] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of this patent.
