DETAILED DESCRIPTION

[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The belt conveyor system of the embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0029] like Figure 1 , Figure 4 and Figure 8 As shown, the belt conveyor system of the embodiment of the utility model may include a belt machine body 100, a tensioning roller 200, a tensioning structure 300, a guide roller 400, a reciprocating structure 500, a movable cleaning structure 600, a scraping structure 700 and a fixed cleaning structure 800.

[0030] The two guide rollers 400 are respectively arranged on the inner side of the bottom of the belt 140 of the belt conveyor body 100, and the two tensioning rollers 200 are respectively arranged on the outer side of the bottom of the belt 140 through the tensioning structure 300 to tension the belt 140 in the vertical direction.

[0031] It should be noted that, by adjusting the tensioning structure 300 , the two tensioning rollers 200 can be moved up and down, so that the belt 140 is in a tensioned state, so as to facilitate cleaning of the belt 140 .

[0032] The movable cleaning structure 600 is movably disposed between the two guide rollers 400 and is located outside the belt 140 .

[0033] The driving end of the reciprocating structure 500 is connected to one of the guide rollers 400 , and the pushing end of the reciprocating structure 500 is connected to the mobile cleaning structure 600 .

[0034] It should be noted that the movable cleaning structure 600 abuts against the outer side of the belt 140 along the lateral direction, and can clean the outer side of the belt 140 as it moves back and forth.

[0035] The scraping structure 700 and the fixed cleaning structure 800 are respectively disposed on both sides of the moving cleaning structure 600 and abut against the outer side of the belt 140 .

[0036] It is understandable that after conveying the material, the belt 140 is conveyed to the bottom and moves sequentially from the scraping structure 700, the movable cleaning structure 600 and the fixed cleaning structure 800. Through sequential cleaning, deep multi-level cleaning of the outer side of the belt 140 can be achieved.

[0037] In addition, the two guide rollers 400 are each disposed between the two tension rollers 200 and located below the two tension rollers 200 .

[0038] As a possible situation, the scraping structure 700 , the movable cleaning structure 600 and the fixed cleaning structure 800 are all disposed between two guide rollers 400 .

[0039] Specifically, when the belt 140 is transporting materials, especially sticky materials with strong adhesion, the belt 140 automatically rotates to the bottom after transporting the materials, and passes through the scraping structure 700, the mobile cleaning structure 600 and the fixed cleaning structure 800 in sequence.

[0040] The material initially adhered to the belt 140 is scraped off by the scraping structure 700 and then falls off, and the remaining material adhered to the belt 140 moves with the belt 140 to the mobile cleaning structure 600. When the guide roller 400 rotates with the belt 140, it drives the driving end of the reciprocating structure 500, so that the reciprocating structure 500 can push the mobile cleaning structure 600 to reciprocate in the horizontal direction to clean the outer side of the belt 140.

[0041] As the belt 140 moves, after passing through the mobile cleaning structure 600 , it reaches the fixed cleaning structure 800 , and the fixed cleaning structure 800 performs a final cleaning on the belt 140 .

[0042] The outer surface of the belt 140 has been cleaned after passing through the scraping structure 700, the movable cleaning structure 600 and the fixed cleaning structure 800. Then, as the belt 140 continues to move, subsequent materials are transported to ensure the continuity of the operation.

[0043] In one embodiment of the present invention, Figure 1 and Figure 4 As shown, the belt conveyor body 100 further includes a side plate 110 , a driving roller 120 and a driven roller 130 .

[0044] The active roller 120 and the driven roller 130 are rotatably disposed between the two side plates 110 , respectively. The belt 140 is sleeved on the active roller 120 and the driven roller 130 . The active roller 120 is externally connected to a driving motor 101 .

[0045] It should be noted that the driving motor 101 drives the active roller 120 , so that the active roller 120 drives the belt 140 to transmit, so as to realize the conveyance of materials.

[0046] In one embodiment of the present invention, Figure 3 As shown, the tensioning structure 300 includes a bearing seat 310 , a threaded rod 320 , a mounting bracket 330 and a joint 340 .

[0047] Among them, vertical first sliding grooves 111 are respectively opened on the two side plates 110, and the two ends of the tensioning roller 200 slide along the first sliding grooves 111 respectively and are connected to the bearing seat 310 arranged outside the side plate 110. The mounting frame 330 is fixed outside the side plate 110. One end of the threaded rod 320 can be rotatably set on the bearing seat 310, and the other end is threadedly connected to the mounting frame 330 and extends upward. The joint 340 is set at the extended end of the threaded rod 320.

[0048] It should be noted that relevant staff can use tools (such as wrenches, etc.) to rotate the joint 340 so that the threaded rod 320 rotates accordingly and rises and falls. At this time, the rising and falling threaded rod 320 drives the bearing seat 310 to rise and fall, so that the tensioning roller 200 connected to the bearing seat 310 slides in the first slide groove 111.

[0049] In one embodiment of the present invention, Figure 5 As shown, the reciprocating structure 500 includes a wheel plate 510 , an eccentric rod 520 , a connecting rod 530 , and a connecting shaft 540 .

[0050] The wheel disc 510 is coaxially arranged with the guide roller 400 , the eccentric rod 520 is eccentrically arranged on the wheel disc 510 , one end of the connecting rod 530 is pivotally connected to the eccentric rod 520 , and the other end is pivotally connected to the mobile cleaning structure 600 through the connecting shaft 540 .

[0051] It should be noted that when the guide roller 400 rotates under the action of the friction force of the belt 140, it can drive the wheel 510 connected to it to rotate, and the eccentric rod 520 follows to rotate, and drives the connecting rod 530 to move, so that the connecting rod 530 pulls the connecting shaft 540 to move, and at this time the mobile cleaning structure 600 follows the connecting shaft 540 to move back and forth.

[0052] To clearly illustrate the above embodiment, in one embodiment of the present utility model, as Figure 2 As shown, a second slide groove 112 is opened on the side plate 110 , and a rotatable roller 601 is arranged outside the mobile cleaning structure 600 . The roller 601 is embedded in the second slide groove 112 and is rollingly connected to the second slide groove 112 .

[0053] It should be noted that when the mobile cleaning device moves, the roller 601 rolls in the second slide groove 112, which not only limits the mobile cleaning device to move in a fixed direction (i.e., moving along the outside of the belt 140), but also reduces friction resistance, making the movement of the mobile cleaning device smoother.

[0054] In one embodiment of the present invention, Figure 7As shown, the mobile cleaning structure 600 and the fixed cleaning structure 800 both include a mounting base 610 and a cleaning cotton 620 .

[0055] The cleaning cotton 620 is embedded in the mounting base 610 , and the top of the cleaning cotton 620 abuts against the belt 140 .

[0056] It should be noted that the mounting base 610 of the fixed cleaning structure 800 is fixedly disposed between the two side plates 110 ; the mounting base 610 of the movable cleaning structure 600 passes through the second sliding groove 112 via the connecting shaft 540 and reciprocates.

[0057] In one embodiment of the present invention, Figure 6 As shown, the scraping structure 700 includes a scraper 710 , a rotating sleeve 720 , a fixed shaft 730 and a torsion spring 740 .

[0058] Among them, the scraping end of the scraper 710 abuts against the outer side of the belt 140, and a rotating sleeve 720 is provided in the middle of the other side. The fixed shaft 730 passes through the rotating sleeve 720, and the two ends of the fixed shaft 730 are respectively fixed in the belt conveyor body 100. The torsion spring 740 is sleeved on the fixed shaft 730, and the two ends of the torsion spring 740 are respectively connected to the belt conveyor body 100 and the rotating sleeve 720.

[0059] It should be noted that under the reset action of the torsion spring 740, the rotating sleeve 720 can always be driven to perform reset movement. When the scraper 710 follows the rotating sleeve 720 to reset, it always maintains contact with the outside of the belt 140 to ensure the scraping effect of the material adhering to the belt 140.

[0060] In summary, according to the belt conveyor system of the embodiment of the utility model, the scraping structure 700, the mobile cleaning structure 600 and the fixed cleaning structure 800 are arranged in sequence, so the outer wall of the belt can be cleaned in sequence to improve the overall cleaning efficiency. The mobile cleaning structure 600 reciprocates along the outer side of the belt 140 under the drive of the reciprocating structure 500, which is particularly suitable for processing materials with high viscosity, ensuring the thoroughness of cleaning, and is more suitable for industrial environments with continuous operations.
