Description

Technical Field

[0001] The invention relates to the technical field related to mechanical processing and conveying, and in particular to a double-layer belt conveyor line with automatically adjusted width. Background Art

[0002] After massive searches, it was found that the existing Chinese patent announcement number is CN220097511U, which discloses a belt conveyor device and a belt conveyor, and relates to the field of material conveying technology. The belt conveyor device arranges two shielding mechanisms horizontally and side by side on a transmission frame, and the conveyor belt wound around the active roller and the driven roller is located between the two shielding mechanisms. In this way, the shielding mechanism can be used to prevent the material on the conveyor belt from falling from the side of the conveyor belt, thereby preventing the material from falling onto the conveyor belt and minimizing damage to the conveyor belt.

[0003] Currently, most belt conveyor lines on the market are fixed width, and some width-adjustable belt conveyor lines are single-layer belt conveyor lines with adjustable width, or the adjustment method is manual adjustment. Therefore, the above methods have the following problems:

[0004] Fixed-width belt conveyor line: Its width is a fixed value, and its compatibility with products of different sizes and widths is not high. When conveying products with a width smaller than the belt width, its positioning accuracy is also relatively low.

[0005] Manual width adjustment: The width adjustment varies with the subjective changes of the personnel, the workload of the personnel is relatively large, and the operator may make inaccurate adjustments or mistakes, which will cause poor product production.

[0006] In view of the above-mentioned defects, the designers actively carried out research and innovation in order to create a double-layer belt conveyor line with automatic width adjustment to make it more valuable for industrial use. Summary of the invention

[0013] A spacing adjustment component is arranged on the bottom plate between the fixed side component and the movable side component, and the spacing adjustment component drives the movable side component on the left to move in the left-right direction.

A left lower cross frame 14 and a left upper cross frame 15 are installed on the left fixed bracket 13 in sequence from bottom to top. A lower conveying motor module 16 installed on the right lower cross frame 11 drives a right lower synchronous belt 17 located on the right lower cross frame 11 to run in the front-to-back direction. An upper conveying motor module 19 installed on the right upper cross frame 12 drives an upper right synchronous belt 20 located on the right upper cross frame 12 to run in the front-to-back direction.

[0038] A lower cover plate 2 is installed between the right lower cross frame 11 and the left lower cross frame 14 , and an upper cover plate 3 is installed between the right upper cross frame 12 and the left upper cross frame 15 .

The driving end of the lower conveying motor module 16 runs in the front-to-back direction through the lower synchronous shaft 18 and the left lower synchronous belt 27 located on the left lower cross frame 25, and the driving end of the upper conveying motor module 19 runs in the front-to-back direction through the upper synchronous shaft 21 and the left upper synchronous belt 28 located on the left upper cross frame 26;

[0040] A fixed side guide plate 4 is installed on the outer side of the right fixed bracket 10 , a movable side guide plate 5 is installed on the outer side of the left fixed bracket 13 , and a conveyor belt guard 6 is installed on the outer side of the lower synchronous shaft 18 and the upper synchronous shaft 21 .

[0041] A plurality of guide shafts 22 distributed along the left-right direction are installed between the upper right cross frame 12 and the upper left cross frame 15 , and the upper left cross frame 26 is connected to the guide shafts 22 via guide bearings 29 .

[0042] A regularization block 23 is installed at the bottom of the lower right horizontal frame 11 and the upper right horizontal frame 12. The regularization block 23 moves along the front-rear direction under the action of the regularization cylinder to regularize the products in the conveying process.

[0043] 3. A spacing adjustment component 9 is provided on the bottom plate 1 between the fixed side component 7 and the movable side component 8. The spacing adjustment component 9 drives the movable side component 8 on the left to move in the left-right direction.

[0047] The upper and lower conveying structures convey the products separately. The two are independent of each other, but they can move synchronously when adjusted left and right.

[0048] When the width of the conveyor line needs to be adjusted for products of different widths, the spacing adjustment component 9 drives the movable side component to move toward the fixed side component or vice versa, thereby realizing automatic adjustment of the width of the upper and lower conveyor lines.

[0049] The width of the conveyor line is adjustable, which makes it more compatible with products of different sizes and widths, and can be adjusted for products of different widths.

[0050] The automatic adjustment method saves more manpower and also ensures higher position repeatability accuracy each time the adjustment is made, thus avoiding the problem of increased production defect rate caused by unstable operation of personnel.

[0051] The double-layer conveyor line adopts the same set of width adjustment mechanisms, which ensures the consistency of width adjustment of the upper and lower conveyor lines, while saving a set of width adjustment mechanisms and saving mechanism costs.
