Description

Technical Field

[0001] The invention relates to the technical field of conveyors, and in particular to an anti-deflection load-bearing roller group. Background Art

[0002] The main function of the roller is to support the weight of the conveyor belt and materials, and the operation of the roller must be flexible and reliable to reduce the contact friction on the conveyor belt. As a smaller structural component in the conveyor, the roller plays a very important role.

[0003] When existing rollers carry conveyor belts, they often form an angle with the plane of the conveyor belt's moving direction due to material pressure, contact friction with the conveyor belt, etc., which results in an offset gap between the rollers and the conveyor belt. Under normal circumstances, the bolts that fix the rollers need to be tightened or loosened manually to adjust the gap size, which is not only inefficient, but also requires downtime, affecting production progress.

[0004] In a belt conveyor roller group with patent number CN118270446B, the rollers are rotationally supported by flat support shafts and side support shafts, and an oil pressure adjustment mechanism corresponding to the flat support shafts and side support shafts is provided. A plurality of adjustment cylinders are used to adjust the pressure applied to the flat support shafts and side support shafts, thereby adjusting the angle of the rollers and reducing the deviation of the conveyor belt. However, since the prior art requires that a plurality of adjustment cylinders be connected to a plurality of flat and side support shafts respectively, and the shaft structure is supported and fixed by a specific bracket, the roller specifications adapted by its adjustment mechanism are fixed, and it is impossible to form a matching angle adjustment effect according to rollers of different shaft diameters, and there are certain limitations in the scope of use of the rollers.

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] Reference Figure 1-Figure 6 The present invention provides an anti-deflection load-bearing roller group, comprising:

[0046] A base 1, a flat roller 2 is rotatably connected to the center of the base 1, side rollers 3 are symmetrically arranged at both ends of the flat roller 2, and the side rollers 3 are arranged at an angle with the flat roller 2;

[0047] The adjusting mechanism includes an adjusting plate 5 and a supporting wheel 4 connected to the adjusting plate 5. A lifting rod 6 is provided on the base 1, and a connecting plate 7 is provided on the lifting end of the lifting rod 6. The connecting plate 7 is connected to the adjusting plate 5 through a telescopic member. The telescopic member is used to adjust the distance between the adjusting plate 5 and the adjacent flat roller 2 or side roller 3. A pressure sensor 8 is provided on the adjusting plate 5 and is connected to the telescopic member in communication. The detection end of the pressure sensor 8 is connected to the supporting wheel 4. The supporting wheel 4 is used to roll in contact with the adjacent flat roller 2 or side roller 3.

[0048] The adapter is arranged on the adjusting plate 5 , and the adjusting plate 5 is rotated relative to the lifting rod 6 through the adapter so that the supporting wheel 4 is distributed in parallel with the flat roller 2 or the side roller 3 .

[0049] The present invention provides anti-deflection support for the flat roller 2 and the side roller 3 (hereinafter selectively collectively referred to as the rollers), by arranging an adjustment mechanism on the base 1, and supporting the flat roller 2 and the side roller 3 by using the adjustment plate 5 and the support wheel 4 in cooperation, and driving the connecting plate 7 to rise and fall by the lifting rod 6, so that the support wheel 4 on the adjustment plate 5 can correspond to the height of the flat roller 2 or the side roller 3 in rolling contact with each other, and adjusting the distance between the support wheel 4 and the adjacent flat roller 2 and the side roller 3 by the telescopic member, so as to meet the support function of the support wheel 4 for rollers of different specifications.

[0050] In addition, the pressure sensor 8 provided on the adjustment plate 5 is connected in communication with the telescopic member, so that when the flat roller 2 or the side roller 3 is deflected, the support wheel 4 in sliding contact therewith immediately transmits the pressure change to the pressure sensor 8 through the adjustment plate 5, and the deflection of the flat roller 2 or the side roller 3 is obtained. The pressure sensor 8 is connected in communication with the telescopic member, and the telescopic member is used to adjust the distance between the support wheel 4 and the flat roller 2 and the side roller 3, thereby adjusting the supporting force of the flat roller 2 and the side roller 3, and then realizing the adjustment of the angle of the roller structure, achieving the anti-deflection effect, and improving the applicability of the anti-deflection adjustment of the roller structure.

[0051] By rotating the adjustment plate 5 through the rotating part, the support wheel 4 is kept parallel to the flat roller 2 and the side roller 3. This is not only to adapt the inclination angles of the flat roller 2 and the side roller 3 to maintain the rolling contact effect between the support wheel 4 and the roller structure, but also to ensure that the support wheel 4 is in parallel contact with the roller surface when the roller is deflected, thereby reducing the damage to the roller structure due to strong friction contact.

[0052] In the present technical solution, the lifting rod 6 is a common structure such as a common electric telescopic rod, a cylinder, etc., and no further description will be given.

[0053] Further, the telescopic member comprises:

[0054] The inclined rod 9 is connected to the bottom end of the connecting plate 7, and one end of the inclined rod 9 away from the connecting plate 7 is hinged to the center of the adjusting plate 5;

[0055] The hydraulic rotary machine 10 is fixedly connected to one side of the connecting plate 7. A rotating rod 11 is connected to the bottom end of the connecting plate 7. The output end of the hydraulic rotary machine 10 is fixedly connected to the axis of one side of the rotating rod 11. The inclined rod 9 is fixedly connected to the side wall of the rotating rod 11.

[0056] The hydraulic rotating machine 10 is used to drive the inclined rod 9 to rotate, and the end of the inclined rod 9 away from the connecting plate 7 is hinged to the adjusting plate 5, so as to adjust the distance between the adjusting plate 5 and the connecting plate 7, and then adjust the distance between the supporting wheel 4 and the roller structure to ensure that the supporting wheel 4 can be in rolling contact with the roller.

[0057] Further, the adapter comprises:

[0058] The adapter plate 12 is connected to the center of the adjustment plate 5. A rotating cylinder 13 is fixedly connected to the side of the adjustment plate 5 away from the adapter plate 12. The output shaft of the rotating cylinder 13 penetrates the adjustment plate 5 and is fixedly connected to the adapter plate 12.

[0059] One end of the inclined rod 9 away from the connecting plate 7 is hinged to the center of the adapter plate 12 .

[0060] In addition, in the present technical solution, the rotating cylinder 13 is fixedly connected to the adjusting plate 5, and the adapter plate 12 is driven by the rotating cylinder 13. The adapter plate 12 is connected to the adjusting plate 5, and the adapter plate 12 is hinged to the inclined rod 9 to realize the rotation adjustment of the adjusting plate 5, thereby ensuring that the supporting wheel 4 is parallel to the adjacent flat roller 2 or side roller 3.

[0061] Furthermore, the regulating mechanism also includes:

[0062] The adjusting seat 14 is arranged on the side of the adjusting plate 5 close to the flat roller 2 or the side roller 3. The detection end of the pressure sensor 8 is connected to the adjusting seat 14. A groove is opened on the adjusting seat 14. An elastic component is arranged in the groove. The elastic component is connected to the supporting wheel 4 so that the supporting wheel 4 forms an elastic tendency in the direction away from the groove.

[0063] The support wheel 4 is elastically connected to the adjustment seat 14. When the roller structure deflects, the support wheel 4 feeds back the pressure change and transmits it to the adjustment seat 14. The pressure change signal is received by the pressure sensor 8, and the roller deflection occurs. According to the positive and negative values ​​of the pressure change, the support wheel 4 is adjusted to retract and extend. In addition, since the support wheel 4 is connected to the adjustment seat 14 through the elastic component, after the deflection occurs, the contact plane between the roller and the support wheel 4 has been dislocated. The elastic component adaptively deforms elastically, which can reduce the situation where the support wheel 4 generates a strong friction contact level with the roller, thereby effectively protecting the roller structure.

[0064] Furthermore, the elastic component includes:

[0065] A pair of first support rods 15 are symmetrically arranged on both sides of the groove. The part of the first support rod 15 extending into the groove is fixedly connected to the side wall surface of the gear 16. The two gears 16 on the pair of first support rods 15 are meshed with each other. The axis of the gear 16 is penetrated and fixedly connected with a second support rod 17. The two ends of the second support rod 17 are connected to the opposite sides of the inner wall surface of the groove. The first support rod 15 is connected to the support wheel 4 in a direction away from the groove. The two support wheels 4 respectively located on the pair of first support rods 15 are symmetrically distributed on both sides of the flat roller 2 or the side roller 3 along the central axis.

[0066] The torsion spring 18 is sleeved on the second support rod 17 , and two ends of the torsion spring 18 are fixedly connected to the inner wall surface of the groove and the side wall surface of the gear 16 respectively.

[0067] Furthermore, a plurality of adjustment plates 5 are provided, and the plurality of adjustment plates 5 are symmetrically arranged on both sides of the flat roller 2 and the side roller 3 along the central axis.

[0068] A pair of first support rods 15 are symmetrically connected in the grooves formed on the adjustment seat 14, and the pair of first support rods 15 are meshed with each other by means of gears 16. The pair of first support rods 15 extend out of the grooves in a Y shape, so that the support rollers on the pair of first support rods 15 can be symmetrically distributed along the central axis of the adjacent flat rollers 2 or side rollers 3. Under the elastic action of the torsion spring 18, a clamping force is formed toward the flat roller 2 or the side roller 3, thereby improving the support stability of the rollers.

[0069] It can be understood that at least four support wheels 4 on both sides of the roller can support the roller in four directions along the circumference of the roller. When the roller deflects, the pressure sensor 8 connected to the support wheel 4 can efficiently feedback the pressure change data, thereby helping the staff to quickly determine the deflection direction of the roller, and further improve the overall device's anti-deflection effect on the roller.

[0070] Furthermore, at least two adjustment seats 14 are disposed on any adjustment plate 5 , and the two adjustment seats 14 are symmetrically disposed on both sides of the adjustment plate 5 , and the number of pressure sensors 8 and the number of adjustment seats 14 are the same and correspond one to one.

[0071] By respectively arranging adjustment seats 14 on both sides of the adjustment plate 5, and elastically arranging support wheels 4 on each adjustment seat 14, when the flat roller 2 and the side roller 3 produce lateral deflection, the support wheels 4 that were originally in rolling contact with the flat roller 2 or the side roller 3 on the same plane produce corresponding pressure changes. By observing the recorded information of the pressure sensor 8, when on the two adjustment seats 14 in the same adjustment plate 5, the pressures of the two support wheels 4 on one side of the adjustment seat 14 increase at the same time, while the pressures of the two support wheels 4 on the other side of the adjustment seat 14 decrease at the same time, it can be directly judged that the flat roller 2 or the side roller 3 has deflected in the horizontal direction, thereby improving the use effect.

[0072] Furthermore, it also includes:

[0073] The rotating motor 19 is arranged between the connecting plate 7 and the lifting rod 6. The connecting rods 20 are connected to both sides of the top of the lifting rod 6. The side walls of the connecting rods 20 are fixedly connected with fixed plates 21. The fixed plates 21 are fixedly connected to the connecting plate 7. The rotating motor 19 is fixedly connected to the side walls of the connecting rods 20. The output shaft of the rotating motor 19 passes through the connecting rods 20 and is fixedly connected to the lifting rod 6.

[0074] The rotation angle of the connecting plate 7 is provided by rotating the motor 19. When the flat roller 2 or the side roller 3 has a large structure, which makes it inconvenient for the supporting wheel 4 to directly clamp the roller structure, or when the lifting rod 6 is located obliquely below the flat roller 2 or the side roller 3, the connecting plate 7 can be rotated by rotating the motor 19 to increase the distance between the adjusting plate 5 and the roller structure. Since the oblique rod 9 is hinged to the adjusting plate 5, when the rotation angle of the connecting plate 7 changes, the supporting wheel 4 can also effectively roll in contact with the flat roller 2 or the side roller 3, thereby further improving the application range of the anti-deflection device.

[0075] Furthermore, it also includes:

[0076] The first brackets 22 are respectively arranged at both ends of the flat roller 2, the first brackets 22 are fixedly connected to the base 1, and the flat roller 2 is transfer-connected to the first brackets 22;

[0077] The second bracket 23 is arranged at the end of the side roller 3 away from the flat roller 2. The side roller 3 is connected to the second bracket 23. The end of the side roller 3 close to the flat roller 2 is connected to the first bracket 22. The mutually close sides of the first bracket 22 and the second bracket 23 are inclined end surfaces parallel to each other.

[0078] The flat roller 2 and the side roller 3 are supported by the first bracket 22 and the second bracket 23 , so that the side roller 3 is symmetrically arranged along the center of the flat roller 2 and an angle is generated between the side roller 3 and the flat roller 2 .

[0079] Furthermore, it also includes:

[0080] There are several buffer seats 24, which correspond to the ends of the flat roller 2 and the side roller 3 one by one. The ends of the flat roller 2 and the side roller 3 are transferred to the adjacent buffer seats 24. The first bracket 22 and the second bracket 23 are vertically provided with buffer grooves, and the buffer seats 24 are slidably connected in the buffer grooves.

[0081] The hydraulic buffer 25 is disposed in the buffer groove, and two ends of the hydraulic buffer 25 are respectively against the buffer seat 24 and the inner wall surface of the buffer groove.

[0082] The hydraulic buffer 25 is used to support the buffer seat 24 along the axial direction of the buffer groove, and the buffer seat 24 is coaxially connected with the flat roller 2 and the side roller 3, thereby providing a buffer support effect for the roller structure.

[0083] The working principle of the anti-deflection load-bearing roller group of the present invention is:

[0084] The connecting plate 7 is driven to rise and fall by the lifting rod 6, and the height of the adjusting plate 5 is adjusted according to the structure of the flat roller 2 or the side roller 3 to be anti-deflected. After the adjusting plate 5 corresponds to the flat roller 2 in the horizontal direction, the inclined rod 9 is rotated by the hydraulic rotating machine 10, and the inclined rod 9 drives the adjusting plate 5 to extend relative to the connecting plate 7. When the adjusting plate 5 approaches the flat roller 2 or the side roller 3, the rotating motor 19 rotates the adjusting plate 5, so that the supporting wheel 4 rolls in parallel with the surface of the flat roller 2 or the side roller 3, thereby completing the adaptive support for rollers of different specifications.

[0085] When the roller deflects, the contact pressure between the support wheel 4 and the roller changes, and the first support rod 15, the gear 16 and the second support rod 17 transmit the pressure to the adjustment seat 14, and the pressure change transmitted by the adjustment seat 14 is received by the pressure sensor 8. The pressure sensor 8 is used to communicate with the hydraulic rotary machine 10, and the hydraulic rotary machine 10 rotates the inclined rod 9 to control the support wheel 4 to adjust the distance between it and the roller, and according to the positive and negative values ​​of the pressure change, the support wheel 4 is retracted and extended to form a reset support force for the deflected roller. When it cannot be reset for a long time, the machine can be stopped to repair the roller at the deflection position, thereby improving the anti-deflection effect of the overall device.

[0086] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0087] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention.
