Belt conveyor

Abstract

A belt conveyor comprises a machine frame, and tensioning holes and a plurality of roller adjusting holes are formed in the same positions of the two side walls of the machine frame. The tensioning hole is used for enabling the driven roller arranged at the position to transversely and horizontally move under the action of a tensioning device; and the roller adjusting hole is used for enabling the driven roller arranged at the roller adjusting hole to transversely and horizontally displace and / or horizontally rotate by adjusting the fixed bearing seat. A plurality of roller adjusting holes are formed in the two side walls of the rack, and horizontal displacement and / or horizontal rotation of the driven roller are / is adjusted by adjusting transverse horizontal displacement and / or horizontal rotation of the fixed bearing seat in a matched mode. Therefore, even if the belt still deviates after the tensioning device is tensioned, the deviation condition of the belt can be eliminated by adjusting the horizontal displacement and / or horizontal rotation of the driven roller, and the problem that the belt still deviates only by adjusting the tensity of the two ends of the driven roller of an existing belt conveyor is solved.

Description

Technical Field

[0001] The present application relates to the technical field of belt conveyors, and in particular to a belt conveyor. Background Art

[0002] Belt conveyors are mainly used to transport materials from the initial feeding point to the final unloading point. They can be used to transport both loose materials and finished goods. Therefore, belt conveyors have the characteristics of strong conveying capacity, long conveying distance, simple structure, easy maintenance, and convenient program control and automatic operation. The continuous or intermittent movement of the conveyor belt is used to transport goods or powdery and granular goods. It runs at high speed, smoothly, with low noise, and can be transported up and down slopes.

[0003] The belt conveyor is mainly composed of a frame, a conveyor belt, rollers, a drum, a tensioning device, a transmission device, etc. It is a device that transports materials in a continuous manner through friction drive. Most of the tensioning adjustment devices of belt conveyors in the prior art are set at the ends to adjust the tension at both ends of the driven drum to prevent the belt from deviating. However, there are many external factors that cause the belt to deviate, such as: 1. The centers of the head, tail, and middle frame are not in a straight line; 2. The installation position of the drum is not correct, causing the belt to deviate from the drum; 3. The conveyor belt joint is not correct, causing the middle part of the conveyor belt to deviate; 4. The installation angle of the roller is not accurate enough to cause the belt to deviate, etc. Therefore, simply adjusting the tension at both ends of the driven drum can no longer meet the deviation in the above situation. A new belt conveyor is urgently needed so that it can not only meet the tension requirements of the belt conveyor in the above situation but also adjust the belt deviation problem. Utility Model Content

[0004] The present application provides a belt conveyor, which can be used to solve the problem that the belt of the existing belt conveyor still deviates in some cases only by adjusting the tension at both ends of the driven roller.

[0005] The present application provides a belt conveyor, which includes a frame, and two side walls of the frame are provided with tensioning holes and a plurality of roller adjustment holes at the same position;

[0006] Wherein, the tensioning hole is used to enable the driven roller arranged at this position to be horizontally displaced laterally under the action of the tensioning device;

[0007] The roller adjustment hole is used to allow the driven roller arranged thereto to be laterally displaced and / or horizontally rotated by adjusting the fixed bearing seat.

[0008] Furthermore, each of the roller adjustment holes includes two upper and lower elongated waist holes, and a circular through hole located between the two elongated waist holes;

[0009] The long waist hole is used to fasten the fixed bearing seat by bolts or adjust the fixed bearing seat;

[0010] The diameter of the circular through hole is greater than the shaft diameter of the driven roller, so that the driven roller has an adjustment space.

[0011] Furthermore, the upper and lower elongated waist holes of each of the roller adjustment holes are arranged horizontally, and the upper and lower elongated waist holes are arranged staggered.

[0012] Furthermore, one end of the two side walls of the frame is provided with a driving roller, and the other end of the two side walls of the frame is provided with an end driven roller;

[0013] At least three roller adjustment holes are arranged at the same position on both side walls of the frame and are arranged at an obtuse angle, so that the belt under the driving roller first runs obliquely upward, then runs obliquely downward, and finally runs horizontally;

[0014] The upper tangent point of the driven roller at the tensioning hole and the lower tangent point of the end driven roller are at the same horizontal position.

[0015] Furthermore, observation holes 5 are provided at the tensioning hole and the drum adjustment hole.

[0016] Furthermore, the tensioning hole and the roller adjustment hole are integrally formed with the corresponding observation hole 5 .

[0017] Furthermore, the center positions of the drum adjustment holes are higher than the center positions of the corresponding observation holes 5 .

[0018] Furthermore, a drive motor, a motor fixing seat and a power distribution control module are also arranged on one side wall of the frame;

[0019] Adjustment holes are arranged on both side walls of the frame, at the positions of the driving roller and the end driven rollers, and the driving motor is hinged to the motor fixing seat, so that the driving roller can be adjusted by horizontal displacement and / or horizontal rotation.

[0020] The solution provided by the present application is that the belt conveyor includes a frame, and tensioning holes and a plurality of roller adjustment holes are provided at the same position on the two side walls of the frame; wherein the tensioning holes are used to allow the driven roller provided at the position to be laterally displaced horizontally under the action of the tensioning device; and the roller adjustment holes are used to allow the driven roller provided at the position to be laterally displaced horizontally and / or horizontally rotated by adjusting the fixed bearing seat. The two side walls of the frame of the present application are provided with a plurality of roller adjustment holes, and the horizontal displacement and / or horizontal rotation of the driven roller can be adjusted by adjusting the horizontal displacement and / or horizontal rotation of the fixed bearing seat. Therefore, even if the belt is still offset after the tensioning device is stretched, the belt offset can be eliminated by adjusting the horizontal displacement and / or horizontal rotation of the driven roller, thereby solving the problem that the belt of the existing belt conveyor still deviates even if the tension is only obtained by adjusting the tension at both ends of the driven roller.

DETAILED DESCRIPTION

[0028] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0029] Combine the following Figures 1 to 5 The belt conveyor of this application is introduced. Unless otherwise specified, the description of the front, back, left, right, up, down, etc. of this application is based on Figure 1 First, please refer to Figure 1 , which shows a three-dimensional structural schematic diagram of a belt conveyor that may be applicable to the embodiment of the present application. A belt conveyor of the present application includes a frame 1, and the frame 1 includes two front and rear side walls 11 and 12. A tensioning hole 13 and a plurality of roller adjustment holes 14 are arranged at the same position of the two side walls 11 and 12. A driven roller 23 is arranged between the tensioning hole 13 of the front side wall 12 and the tensioning hole 13 of the rear side wall 11. A driven roller 23 is also arranged between each group of roller adjustment holes 14 between the two side walls. The tensioning hole 13 and the roller adjustment hole 14 can make the end support shaft of the corresponding driven roller 23 extend. The end support shaft of the driven roller 23 at the tensioning hole 13 is connected to the tensioning device 4. The tensioning device 4 can adopt spiral tensioning, electric tensioning and hydraulic tensioning. The tensioning device 4 applies horizontal thrust or pulling force to the end support shaft connected to the driven roller 23, so as to realize the lateral horizontal displacement of the driven roller 23 at this location, and tension the belt 3.

[0030] The end support shaft and the fixed bearing seat 24 of the driven roller 23 at the roller adjustment hole 14, each of the roller adjustment holes 14 includes two upper and lower elongated waist holes 141, and a circular through hole 142 located between the two elongated waist holes 141; the elongated waist hole 141 is used to fasten the fixed bearing seat 24 or adjust the fixed bearing seat 24 by bolts; the diameter of the circular through hole 142 is larger than the shaft diameter of the driven roller 23, so that the driven roller 23 has an adjustment space. The fixed bearing seat 24 is fixed by bolts. When the driven roller 23 needs to be adjusted, the bolts of the fixed bearing seat 24 are screwed, so that the fixed bearing seat 24 can move parallel to the elongated waist hole 141. Therefore, when the fixed bearing seats 24 at both ends of the driven roller 23 are adjusted in the same direction, the driven roller 23 can be horizontally displaced. When the adjustment directions of the fixed bearing seats 24 at both ends of the driven roller 23 are inconsistent, the driven roller 23 can be horizontally rotated. Therefore, when the centers of the machine head, machine tail and middle frame are not in a straight line; the installation position of the roller is not correct, causing the belt 3 to deviate at the roller; the conveyor belt joint is not straight, causing the belt 3 to deviate; the installation angle of the roller is not accurate enough, causing the belt 3 to deviate, etc., the deviation of the belt 3 can be compensated and corrected by adjusting the horizontal rotation of the driven roller 23, thereby solving the problem of the existing belt conveyor still deviating by only adjusting the tension at both ends of the driven roller.

[0031] For further information, please refer to Figure 3 and Figure 5As shown in the schematic diagram, the upper and lower elongated waist holes 141 of each roller adjustment hole 14 are horizontally arranged, and the upper and lower elongated waist holes 141 are staggered, that is, the upper and lower elongated waist holes 141 are parallelly arranged, and the vertical projection of the end of one side of the upper elongated waist hole is located in the middle of the lower elongated waist hole. The design of the waist hole is to reduce the weight of the frame 1, and secondly, the driven roller 23 may generate a rotational torque on its supporting shaft when it is running, and the staggered arrangement of the two elongated waist holes 141 can block the rotation of the fixed bearing seat 24, thereby maintaining the operation of the belt 3 and preventing it from running off.

[0032] Further references Figure 1 , Figure 3 as well as Figure 4 , a driving roller 21 is provided at one end of the two side walls 11, 12 of the frame 1, and an end driven roller 22 is provided at the other end of the two side walls 11, 12 of the frame 1; at least three roller adjustment holes 14 are provided at the same position of the two side walls 11, 12 of the frame 1 and are provided at an obtuse angle, and the specific number of the roller adjustment holes 14 can be determined according to the length of the belt conveyor. It is best to open three roller adjustment holes 14 for a belt conveyor of a general length, and the arrangement method is as follows: Figure 3 As an example, from left to right are the first, second and third roller adjustment holes, the first roller adjustment hole is close to the driving roller 21, and the upper tangent point of the driven roller installed at the first roller adjustment hole is higher than the lower tangent point of the driving roller 21, so that the belt 3 from below the driving roller 21 will run obliquely upward to bypass the driven roller at the first roller adjustment hole. The second roller adjustment hole and the third roller adjustment hole are located at the bottom of the side wall of the frame 1, and the driven rollers at the second roller adjustment hole and the third roller adjustment hole are located on the same straight line, and the belt running between the driven rollers at the second roller adjustment hole and the third roller adjustment hole is parallel to the belt running between the driving roller 21 and the end driven roller 22, so that the belt 3 will run obliquely downward after bypassing the driven roller at the first roller adjustment hole, and run horizontally after bypassing the driven roller at the second roller adjustment hole. In this way, the tensioning effect of the belt can be further improved, thereby further preventing the deviation of the belt 3. In addition, the upper tangent point of the driven roller 23 at the tensioning hole 13 and the lower tangent point of the end driven roller 22 are at the same horizontal position. When the tensioning device 4 applies a horizontal thrust or pull to the end support shaft connected to the driven roller 23, the belt 3 that has been adjusted or compensated will not be damaged and will not deviate again.

[0033] In order to further observe and conveniently adjust the deviation of the belt 3, the tensioning hole 13 and the roller adjustment hole 14 of the present application are both provided with an observation hole 15. The specific structure and shape can be referred to Figure 5As shown in the schematic diagram, the observation hole 15 is preferably circular in shape, and the tensioning hole 13 and the roller adjustment hole 14 are integrally formed with the corresponding observation holes 15, that is, the projection shape of the tensioning hole 13 and the observation hole 15 is similar to a spindle, and the projection shape of the roller adjustment hole 14 and the observation hole 15 is gourd-shaped. In addition, in order to facilitate the observation of the running state of the belt 3 at the tensioning hole 13 and the roller adjustment hole 14, to facilitate the analysis of the deviation cause and to facilitate the observation of the running state of the belt 3 after adjustment or modification, the center position of the roller adjustment hole 14 of the present application is higher than the center position of the corresponding observation hole 15.

[0034] For further information, please refer to Figure 4 As shown in the schematic diagram, a driving motor 211, a motor fixing seat 212 and a power distribution control module 213 are also provided on one side wall of the frame 1; adjustment holes are provided on the two side walls 11 and 12 of the frame 1 at the positions of the driving roller 21 and the end driven roller 22, and the adjustment hole is also composed of two upper and lower elongated waist holes, and an axial hole located between the two elongated waist holes; the driving motor 211 is hinged to the motor fixing seat 212, providing a movable space when the driving roller 21 can be horizontally displaced and / or horizontally rotated, and the function of the elongated waist hole is also to fasten the fixed bearing seat there by bolts or adjust the fixed bearing seat there, so that the lateral horizontal displacement or horizontal rotation adjustment of the driving roller 21 can be realized, which can further improve and solve the deviation problem of the belt 3.

[0035] In summary, the belt conveyor of the present application can not only realize the extension function, but also can solve the deviation of the belt 3 mentioned in the background technology, thereby realizing the smooth operation of the belt conveyor.
