Description

Technical Field

[0001] This invention relates to the technical field of conveyor belts, and more specifically to a method for adjusting a conveyor belt device. Background Technology

[0002] In belt conveyor systems, due to manufacturing and installation precision requirements, the parallelism of the two drive wheels inevitably deviates within an acceptable range. This parallelism deviation can cause the conveyor belt to deform. Specifically, in actual use, the drive wheels will have a certain misalignment, forming an angle with the ideal parallelism baseline. This tilt causes one end of the drive wheel to be further away from the other drive wheel. From an overall structural perspective, the drive wheel resembles the hypotenuse of a trapezoid, with one end flared outwards. This pulls on the material belt wound around it, causing one side of the belt to be elongated along the conveying path. This elongated side could be the left or right side of the belt. The elongated side can cause the workpiece placed on the belt to deviate. For slender belts, the disadvantages are particularly pronounced, as the workpiece may deviate to the edge of the belt or even fall off the edge, seriously affecting the conveying quality. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes an adjustment method for a conveyor belt device, which can correct the deformation of the conveyor belt and maintain the conveying direction of the conveyor belt.

[0004] According to an embodiment of the present invention, the conveyor belt device includes a drive wheel assembly, a material belt, a power assembly, and an adjustment assembly. The drive wheel assembly includes a driving wheel and a driven wheel that are parallel to each other and spaced apart. The driven wheel has a driven shaft coaxially mounted on it. The material belt is wound around the driving wheel and the driven wheel, extending along a conveying path, with the length direction of the material belt being the extension direction of the conveying path. The power assembly drives the driving wheel to rotate. The adjustment assembly includes a pusher located on the outside of one end of the driven shaft and used to push the end of the driven shaft back and forth along the conveying path, thereby straightening the material belt that has undergone length deformation on the left or right side.

[0005] The adjustment method of the conveyor belt device according to embodiments of the present invention has at least the following beneficial effects:

[0006] To avoid affecting the connection dimensions between the drive wheel and the power assembly, and thus preventing interference with power transmission, this embodiment of the invention focuses on the driven wheel. A pusher is provided on one side of the driven wheel, using this pusher to push one end of the driven shaft in a designated direction. Specifically, for the elongated strip on the left side, the pusher extends the right side of the strip by the same length via the driven shaft; for the elongated strip on the right side, the pusher extends the left side of the strip by the same length via the driven shaft, thereby straightening the strip and correcting its conveying direction. The pusher pushes one end of the driven shaft in the designated direction, causing the driven shaft end to move away from or closer to the drive wheel. This pulls the strip in the designated direction, thus correcting its conveying direction. This embodiment of the invention has a simple and scientifically sound structure, effectively adjusting the conveying direction of the strip and improving the quality of workpiece conveying.

[0007] According to some embodiments of the present invention, the adjusting assembly further includes a jacking support, on which the jacking member is movably disposed.

The second jacking member includes a second lifting bolt, which is screwed onto a pre-set threaded hole in the second jacking support.

[0010] According to some embodiments of the present invention, the conveyor belt device further includes a bearing assembly, which includes a bearing housing and a bearing. The end of the driven shaft is inserted into the through hole of the bearing housing through the bearing. A first pusher and a second pusher are respectively disposed on both sides of the bearing housing, and each of the first pusher and the second pusher has one end facing the side of the bearing housing.

[0013] According to some embodiments of the present invention, the conveyor belt device further includes an auxiliary support assembly disposed between the driving pulley and the driven pulley, the auxiliary support assembly being used to provide support for the surface of the feed belt.

[0029] Please see Figures 1 to 4Some embodiments of the present invention provide an adjustment method for a conveyor belt device. The conveyor belt device includes a drive wheel assembly 100, a material belt 200, a power assembly 300, and an adjustment assembly 400. The drive wheel assembly 100 includes a driving wheel 110 and a driven wheel 120 arranged parallel to each other and spaced apart. The driven wheel 120 is coaxially provided with a driven shaft 130. The material belt 200 is wound around the driving wheel 110 and the driven wheel 120. The material belt 200 extends along a conveying path, and the length direction of the material belt 200 is the extension direction of the conveying path. The width of the belt 200 is less than 1:3 in ratio to the conveying path, thus giving the belt 200 a slender shape to save space. It is mainly used for long-distance conveying of small workpieces. The power assembly 300 drives the drive wheel 110 to rotate. The adjustment assembly 400 includes a pusher 410, which is located on the outside of one end of the driven shaft 130 and is used to push the end of the driven shaft 130 back and forth along the conveying path, thereby straightening the belt 200 that has deformed in length on the left or right side.

[0030] Specifically, the pusher 410 pushes the end of the driven shaft 130 back and forth along the conveying path, causing the end of the driven shaft 130 to move away from or closer to the drive wheel 110. Since the driven shaft 130 and the driven wheel 120 are coaxially connected, the pusher 410 can change the orientation of the driven wheel 120, so that the driven wheel 120 can form different angles relative to the ideal parallelism reference line 800, thereby stretching the left or right side of the material belt 200. This causes the material belt 200, which has already undergone length deformation on one side, to undergo further deformation in the same direction on the other side, thereby straightening the material belt 200 and correcting its conveying direction.

[0031] It is worth noting that belts are commonly used in the market as the specific form of the material belt 200. However, once a belt undergoes plastic deformation, it is difficult to restore its original length. In other words, the deformation of the material belt 200 caused by the parallelism deviation of the drive wheel is difficult to repair. The design purpose of this embodiment is not to restore the length of the material belt 200 to its original state, but to lengthen the material belt 200 on the side with less or no stretching deformation, so that the stretching degree on both sides of the material belt 200 is consistent, thereby lengthening the material belt 200 as a whole to a new straightness. For example, for the material belt 200 that is stretched on the left, the pusher 410 is used to stretch the right side of the material belt 200 by the same length via the driven shaft 130; for the material belt 200 that is stretched on the right, the pusher 410 is used to stretch the left side of the material belt 200 by the same length via the driven shaft 130, thereby straightening the material belt 200 and correcting the conveying direction of the material belt 200.

[0032] Furthermore, the adjustment assembly 400 also includes a push support 420, and the push member 410 includes a first push member 411 and a second push member 412. The first push member 411 and the second push member 412 are arranged along the conveying path and each has one end facing the driven shaft 130. The first push member 411 and the second push member 412 are respectively provided on both sides of the driven shaft 130. The end of the driven shaft 130 is pushed by the first push member 411 or the second push member 412, so that the driven shaft 130 tilts in different directions.

[0033] Correspondingly, the jacking support 420 includes a first jacking support 421 and a second jacking support 422. The first jacking member 411 is in the form of a first lifting bolt 411a, which is screwed onto a pre-set threaded hole in the first jacking support 421. The second jacking member 412 is in the form of a second lifting bolt 412a, which is screwed onto a pre-set threaded hole in the second jacking support 422. Under forward or reverse tightening action, the first lifting bolt 411a / second lifting bolt 412a can move closer to or further away from the driven shaft 130, thereby pushing the driven shaft 130 in a specified direction.

[0034] Furthermore, the conveyor belt device also includes a bearing assembly 500, which includes a bearing housing 510 and a bearing 520. The end of the driven shaft 130 is inserted into the through hole of the bearing housing 510 through the bearing 520. The first pusher 411 and the second pusher 412 are respectively disposed on both sides of the bearing housing 510, and each of the first pusher 411 and the second pusher 412 has one end facing the side of the bearing housing 510. The end of the driven shaft 130 is disposed on the bearing housing 510 through the bearing 520 to achieve the positioning of the driven shaft 130. The first pusher 411 or the second pusher 412 should push the bearing housing 510 to indirectly transmit the thrust to the driven shaft 130, thereby preventing direct contact with the circumferential surface of the driven shaft 130 during the correction process and thus preventing interference with the transmission of the driven shaft 130.

[0035] Understandably, the conveyor belt device also includes a base 600, which is located on one side of the material belt 200. The bearing housing 510 and the push support 420 are both fixedly mounted on the base 600. The base 600 has a through hole for the driven shaft 130 to pass through. The base 600 serves as the mounting carrier for the transmission wheel assembly 100, the material belt 200, the power assembly 300, and the adjustment assembly 400, forming a load-bearing foundation for each component.

[0036] To enhance the stability of the transmission motion, driven shafts 130 can be provided on both sides of the driven wheel 120 to reduce the tendency of the wheel body to deflect. In this case, the driven shaft 130 includes a first driven shaft 131 and a second driven shaft 132. The first driven shaft 131 and the second driven shaft 132 are coaxially connected to the two end faces of the driven wheel 120, respectively. Correspondingly, there are two pushers 410, which are respectively provided with the first driven shaft 131 and the second driven shaft 132.

[0037] In addition, the conveyor belt device may also be equipped with an auxiliary support assembly 700, which is disposed between the drive wheel 110 and the driven wheel 120. Specifically, the auxiliary support assembly 700 includes an upper support plate 710, a lower support plate 720, and a connecting block 730 connecting the upper support plate 710 and the lower support plate 720. The upper support plate 710 and the lower support plate 720 are both parallel to the conveying path and arranged in a direction perpendicular to the material belt 200. The distance from the top surface of the upper support plate 710 to the bottom surface of the lower support plate 720 is equal to the outer diameter of the drive wheel 110. The upper support plate 710 and the lower support plate 720 provide support for the upper and lower surfaces of the material belt 200, respectively, to prevent surface quality problems such as dents and deformations of the material belt 200 during conveying.

[0038] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
