Technical Field

[0001] The utility model belongs to the technical field of belt conveyor auxiliary equipment, and particularly relates to a belt deviation prevention device based on a belt conveyor. Background Art

[0002] A belt conveyor is a machine that uses a belt to transport materials. Belt deviation or local bulging of the belt are common faults, requiring regular inspection and maintenance by operators. In the prior art, belt deviation problems are usually corrected by installing anti-deviation rollers. For example, patent publication number CN220200351U discloses a belt anti-deviation device in which rollers are installed on both sides of the belt, which restricts the belt from properly transporting some workpieces with higher height dimensions, resulting in a limited number of products being transported. Furthermore, the device is relatively complex, and the disassembly and replacement of multiple rollers is also relatively troublesome, making it inconvenient to adjust the specific position.

[0003] Therefore, there is an urgent need for a belt deviation prevention device that has a simple structure, can solve the belt deviation problem, and is relatively easy to adjust. Utility Model Content

DETAILED DESCRIPTION

[0024] The following describes the specific embodiments of the present invention in detail with reference to the accompanying drawings so that those skilled in the art can more clearly understand how to practice the present invention. Although the present invention is described in conjunction with its preferred embodiments, these embodiments are merely illustrative and do not limit the scope of the present invention.

[0025] Combined with attachment Figure 1-3As shown, the anti-belt deviation device based on the belt conveyor includes a belt conveyor 1, a belt 2 is arranged in the middle of the belt conveyor 1, side frames 3 are installed on both sides of the belt conveyor 1, a plurality of fixed seats 8 are installed on one side of the bottom of the side frame 3, and a support frame 4 is installed on each of the fixed seats 8, an electric slide rail 1 5 is installed in the support frame 4, an electric slider 15 is slidably installed on the electric slide rail 1 5, a cross plate 7 is installed on one side of the electric slider 15, an electric slide rail 2 is arranged in the cross plate 7, an electric slider 2 9 is slidably installed on the electric slide rail 2, and a limiting strip 6 is installed on the bottom of the electric slider 2 9.

[0026] Specifically, the limit bar 6 includes a straight section 11 and a bending section 10, and the electric slider 29 is installed on the bending section 10, that is, one end of multiple electric sliders 29 is connected to the electric slide rail 2, and the other end is fixed on the limit bar 6. When the electric slider 29 moves on the electric slide rail 2, it drives the limit bar 6 as a whole to move in a direction perpendicular to the belt transmission direction.

[0027] Specifically, a long groove 12 is provided at the bottom of one side of the straight section 11 of the limiting strip 6 , and a blocking strip 13 is installed in the long groove 12 . The long groove 12 is used to accommodate the side edge of the belt 2 .

[0028] Specifically, there are two limit bars 6, which are respectively set on both sides of the belt 2, so as not to affect the normal transportation of the belt 2, especially for some workpieces with larger sizes and a certain height. The limit bars 6 are set on both sides to facilitate the limiting of the side of the belt 2 while ensuring the smooth transportation of some workpieces with larger sizes and a certain height.

[0029] Specifically, an accommodating groove 14 is provided between the side frame 3 and the belt 2. When the cross plate 7 is raised or lowered driven by the electric slide rail 4, the bottom of the limit bar 6 can be placed in the accommodating groove 14 without affecting the normal transmission of the belt 2, and the width of the accommodating groove 14 is 1.5 times the width of the bottom of the limit bar 6.

[0030] Specifically, the thickness of the long groove 12 is 1.5 times the thickness of the belt 2 , that is, when the long groove 12 limits the side of the belt 2 , it will not affect the normal transmission of the belt 2 .

[0031] Specifically, the belt conveyor 1, the electric slide rail 1 5 and the electric slide rail 2 are all electrically connected to an external industrial control computer, and the automatic adjustment of the limit bar 6 is achieved through the external industrial control computer.

[0032] Specifically, the baffle 13 is made of wear-resistant polyurethane material, that is, wear-resistant sponge, which is beneficial to reduce the wear of the side of the belt 2 on the baffle 13, and the disassembly of the baffle 13 is also relatively convenient. One side of the baffle 13 is mainly fixed in the long groove 12 by bonding. When replacement is needed, the baffle 13 can be directly torn off and replaced with a new baffle.

[0033] In addition, the width of the long groove 12 is set to 0.1 times the width of the belt 2, which can effectively limit the side of the belt 2.

[0034] The following describes the specific working process of the belt conveyor-based anti-belt deviation device of the utility model:

[0035] When the workpiece is discharged from the tail of the drum sand shakeout machine and transferred to the belt conveyor 1, the external industrial computer controls the electric slide rails 1 and 2 to adjust the height and limit distance of the limit bar 6. In other words, the electric slide rail 1 drives the electric slider 15 to descend to the limit height, so that the long groove 12 of the limit bar 6 can align with the side of the belt 2. Then, the electric slide rail 2 drives the electric slider 2 to move perpendicular to the conveying direction of the belt 2 and close to the center of the belt 2, so that the side of the belt 2 can be limited within the long groove 12, so that the belt 2 will no longer bulge or deviate during transportation. The external industrial computer then controls the belt conveyor 1 to start normal conveying of the workpiece.

[0036] The above is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any modification and replacement based on the technical solution and utility model concept provided by the present invention should be included in the protection scope of the present invention.
