Description

Technical Field

[0001] This utility model belongs to the field of conveying device technology, and specifically discloses a bagged logistics component conveying device with anti-jamming and centering correction structure. Background Technology

[0002] During the material sorting and conveying process in logistics distribution and warehousing centers, bagged logistics items, due to their special shape, undergo significant deformation during transportation. In this deformed and tightly packed state, the bags easily get stuck in the gap between the conveyor belt and the frame. Furthermore, the gap between the conveyor belt and the frame can vary in width due to horizontal displacement and imbalance of the rollers. For these reasons, when a deformed and tightly packed bag meets a narrowing gap, bag jamming can easily occur, thus affecting the conveying quality and efficiency of the conveying device.

[0003] Existing technology constrains the conveyor belt by using limiting rollers and cooperating with guide blocks through limiting grooves. Simultaneously, with all rollers having limiting grooves, an integrated and uninterrupted constraint adjustment method is used to adjust the center position of the conveyor belt to prevent deviation. However, the problem with this technology is that it can cause wrinkles to appear on the conveyor belt during operation, resulting in unstable transmission, as well as deformation and wear of the conveyor belt. Utility Model Content

[0004] The purpose of this utility model is to provide a bagged logistics component conveying device with anti-jamming and centering correction structures to solve the problems of unstable conveying and short service life of the conveyor belt caused by the poor fit between the limiting roller and the guide block.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: This utility model provides a bagged logistics conveying device with anti-sagging and centering correction structures, including a frame. A power roller is rotatably connected to one side of the upper part of the frame in the horizontal direction, and a driven roller that works in conjunction with the power roller is rotatably connected to the other side of the upper part of the frame in the horizontal direction. Multiple idlers are evenly distributed horizontally on the upper part of the frame between the power roller and the driven roller. It also includes a conveyor belt that works in conjunction with the power roller, the driven roller, and the idlers. The inner side of the conveyor belt is provided with a first guide block and a second guide block arranged periodically in the circumferential direction. The power roller, the driven roller, and the idlers are all provided with grooves in the middle in the circumferential direction for the first guide block and the second guide block to pass through. The frame is also provided with a first alignment mechanism and a second alignment mechanism that simultaneously align the first guide block and the second guide block to adjust the centering of the conveyor belt.

[0006] The working principle of this technical solution is as follows: When this conveyor is in operation, the first guide block works in conjunction with the first alignment mechanism, and the second guide block works in conjunction with the second alignment mechanism. The width of the groove is greater than the width of the first guide block and the second guide block, and the groove does not align the first guide block and the second guide block. When the first alignment mechanism aligns the first guide block and the second alignment mechanism aligns the second guide block simultaneously, a center adjustment of the conveyor belt is completed, that is, the distance between the first guide block and the second guide block is equal to the distance between the first alignment mechanism and the second alignment mechanism.

[0007] Preferably, the periodically arranged first guide block and second guide block are one, two or more groups, and each group can satisfy the simultaneous occurrence of the alignment process of the first guide block and the second guide block.

[0008] Furthermore, the first alignment mechanism and the second alignment mechanism have the same structure, both including a first constraint plate and a second constraint plate mounted on the frame. The first constraint plate and the second constraint plate are arranged in parallel. A first deflector is provided on the side of the first constraint plate near the idler roller, and a second deflector is provided on the side of the second constraint plate near the idler roller. The side of the first deflector near the idler roller is inclined to the side away from the second constraint plate, and the side of the second deflector near the idler roller is inclined to the side away from the first constraint plate.

[0009] Furthermore, the first and second levers are arranged symmetrically in a trumpet or V-shape. By setting the first and second levers in a trumpet or V-shape, the problem of the conveyor belt being tripped and stopped due to excessive misalignment can be avoided, thus preventing damage to the conveyor belt.

[0010] Furthermore, the frame is provided with a height adjustment part for adjusting the height of the first constraint plate and the second constraint plate, so as to adapt to guide blocks or conveyor belt models of different heights, thereby expanding the scope of use.

[0011] Furthermore, the height adjustment unit includes a box-shaped base mounted on the frame. A first adjusting rod is rotatably connected to the side of the box-shaped base near the power roller in a vertical direction. A first positioning block is coaxially threaded onto the first adjusting rod. A second positioning block is provided on the side of the first positioning block away from the idler roller. A first constraint plate and a second constraint plate are horizontally mounted on the second positioning block. This arrangement provides high structural stability and ease of operation.

[0012] Furthermore, the first positioning block is symmetrically provided with sliding rods on both sides in the horizontal direction, which are vertically slidably connected to the box-shaped base.

[0013] Furthermore, the second positioning block is provided with a width adjustment part for adjusting the width between the first constraint plate and the second constraint plate. This facilitates adaptation to guide blocks or conveyor belt models of different widths, thereby further expanding its application range.

[0014] Furthermore, the width adjustment part includes a third positioning block disposed on the upper part of the second positioning block; the lower parts of the first constraint plate and the second constraint plate are respectively provided with vertical rods, and the lower parts of the vertical rods are provided with limiting blocks. The first constraint plate and the second constraint plate are horizontally slidably connected to the third positioning block through the vertical rods, the limiting blocks and the third positioning block respectively.

[0015] Furthermore, a sleeve arranged horizontally is provided on the side of the third positioning block near the power roller. A first opening is opened at the middle of the upper part of the sleeve, and a second opening is opened on the side of the upper part of the sleeve near the third positioning block. A second adjusting rod is coaxially threaded to the side of the sleeve away from the third positioning block. A slider is coaxially rotatably connected to one end of the second adjusting rod near the third positioning block. The slider is slidably connected to the sleeve. A fourth positioning block is provided on the upper part of the slider. The fourth positioning block can slide horizontally along the upper part of the second opening. A first connecting plate and a second connecting plate are respectively hinged to the fourth positioning block. The ends of the first connecting plate and the second connecting plate away from the fourth positioning block are respectively hinged to the vertical rods at the lower part of the first constraint plate and the second constraint plate. This allows for simultaneous and equal adjustment of the first constraint plate and the second constraint plate, thereby improving adjustment efficiency.

[0016] Furthermore, the first guide block and the second guide block have the same structure, both being cylindrical, to make the conveyor belt run more smoothly.

[0017] Compared with existing technologies, the beneficial effects of this technical solution are as follows: (1) This scheme uses two alignment mechanisms at the front and rear to simultaneously perform centering correction on the conveyor belt. Compared with the traditional scheme that uses multiple limit slots to constrain the conveyor belt as a whole or in multiple positions, it runs more smoothly and avoids the problem of wrinkles and unevenness in the conveyor belt during operation, thereby improving the conveying efficiency. (2) Only two guide blocks are set on the conveyor belt in this scheme. This reduces the manufacturing cost and makes the conveying operation smoother, thereby further improving the conveying efficiency. At the same time, the reduction in the number of guide blocks reduces the wear of the conveyor belt, thereby extending its service life. Attached Figure Description

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0027] Example 1 like Figure 1 and Figure 2 As shown, this embodiment provides a bagged logistics component conveying device with anti-sagging and centering correction structures, including a frame 1. A power roller 2 is rotatably mounted horizontally on the upper left side of the frame 1. One end of the power roller 2 is coaxially connected to a servo motor, which serves as the power source. A driven roller 3, which works in conjunction with the power roller 2, is rotatably mounted horizontally on the upper right side of the frame 1. Multiple idler rollers 4, preferably four, are evenly rotatably mounted horizontally on the upper part of the frame 1 between the power roller 2 and the driven roller 3. The device also includes a conveyor belt 5 that works in conjunction with the power roller 2, the driven roller 3, and the idler rollers 4.

[0028] like Figure 3 and Figure 4 As shown, the inner side of the conveyor belt 5 is integrally formed or riveted with a first guide block 6 and a second guide block 7 along the circumferential direction. In this embodiment, the first guide block 6 and the second guide block 7 are preferably made of rubber or rigid metal, such as stainless steel. The first guide block 6 and the second guide block 7 have the same structure, both of which are cylindrical structures.

[0029] The driving roller 2, driven roller 3, and idler roller 4 are all circumferentially machined with grooves 8 for the passage of the first guide block 6 and the second guide block 7. The width of the grooves 8 is greater than the width of the first guide block 6 and the second guide block 7. The grooves 8 do not constrain the position of the first guide block 6 and the second guide block 7. The frame 1 is also equipped with a first alignment mechanism 9 for aligning the first guide block 6 and a second alignment mechanism 10 for aligning the second guide block 7.

[0030] like Figure 5 As shown, the first alignment mechanism 9 and the second alignment mechanism 10 in this embodiment have the same structure, and both include a height adjustment part 15 for adjusting the height of the first alignment mechanism 9 and the second alignment mechanism 10, and a width adjustment part 21 for adjusting the width.

[0031] In this embodiment, the first alignment mechanism 9 is preferably a first constraint plate 11 and a second constraint plate 12. The first constraint plate 11 and the second constraint plate 12 are arranged in parallel. A first pawl 13 is integrally formed on the side of the first constraint plate 11 near the idler roller 4, and a second pawl 14 is integrally formed on the side of the second constraint plate 12 near the idler roller 4. The side of the first pawl 13 near the idler roller 4 is inclined away from the side of the second constraint plate 12, and the side of the second pawl 14 near the idler roller 4 is inclined away from the side of the first constraint plate 11. The first pawl 13 and the second pawl 14 are arranged symmetrically in a trumpet shape, preferably V-shaped or figure-eight shaped.

[0032] In the specific implementation process, the first guide block 6 is used in conjunction with the first alignment mechanism 9, and the second guide block 7 is used in conjunction with the second alignment mechanism 10; the width of the groove 8 is greater than the width of the first guide block 6 and the second guide block 7, and the groove 8 does not perform position alignment on the first guide block 6 and the second guide block 7.

[0033] When the first guide block 6 enters the V-shaped structure of the first lever 13 and the second lever 14 of the first alignment mechanism 9, the second guide block 7 also enters the V-shaped structure of the first lever 13 and the second lever 14 of the second alignment mechanism 10. At this time, the centering adjustment of the conveyor belt 5 enters the preparatory stage. The purpose of the preparatory stage is to gradually fine-tune the position of the conveyor belt 5 so that it can smoothly enter the formal stage of centering adjustment. When the first guide block 6 and the second guide block 7 enter the first constraint plate 11 and the second constraint plate 12 of the first alignment mechanism 9 and the first constraint plate 11 and the second constraint plate 12 of the second alignment mechanism 10 at the same time, the centering adjustment enters the formal stage. By simultaneously adjusting the centering of the front and rear ends of the conveyor belt 5, the conveyor belt 5 can smoothly return to the centering position. When the conveyor belt 5 returns to the centering position, it can greatly avoid the problem of bag jamming for the transportation of bagged logistics items. This solution adopts an intermittent adjustment method, which is completely different from the method of continuous constraint in the centering position.

[0034] Example 2 Combination Figure 5 and Figure 6 In this embodiment, the height adjustment part 15 is preferably a box-shaped base 16 mounted on the frame 1. A first adjusting rod 17 is rotatably mounted on the side of the box-shaped base 16 near the power roller 2 in the vertical direction. A first positioning block 18 is coaxially threaded onto the first adjusting rod 17. Slide rods 19 that are vertically slidably connected to the box-shaped base 16 are symmetrically mounted on both sides of the first positioning block 18 in the horizontal direction. In this embodiment, the sliding connection between the slide rod 19 and the box-shaped base 16 is achieved by the sliding holes machined on both sides of the vertical direction of the box-shaped base 16 and the slide rod 19 cooperating with them. A second positioning block 20 is welded to the side of the first positioning block 18 away from the idler roller 4. In the specific implementation process, when the conveyor belt 5 has been used for a certain period of time, it will become loose and slightly deformed, but it has not reached the scrap time. The height of the first alignment mechanism 9 and the second alignment mechanism 10 can be finely adjusted by using the height adjustment part. The adjustment can be made up and down by rotating the first adjustment rod 17.

[0035] Example 3 In this embodiment, the width adjustment part 21 is preferably a third positioning block 22 installed on the upper part of the second positioning block 20, such as Figure 6 and Figure 7As shown, a vertical rod 23 is welded to the lower part of the first constraint plate 11, and a limit block 24 is installed at the lower part of the vertical rod 23. The first constraint plate 11 is horizontally slidably connected to the third positioning block 22 through the vertical rod 23, the limit block 24, and the second constraint plate 12 is welded to the lower part of the second constraint plate 12. Another vertical rod 23 is welded to the lower part of the second constraint plate 12, and another limit block 24 is installed at the lower part of the second constraint plate 23. The second constraint plate 12 is horizontally slidably connected to the third positioning block 22 through the vertical rod 23, the limit block 24, and the third positioning block 22. A sleeve 25 arranged horizontally is installed on the side of the third positioning block 22 near the power roller 2. A first opening 26 is machined at the middle of the upper part of the sleeve 25, and a second opening 27 is machined on the side of the upper part of the sleeve 25 near the third positioning block 22. A second adjusting rod 28 is coaxially threadedly installed on the side of the sleeve 25 away from the third positioning block 22. A slider 29 is coaxially rotatably installed on the end of the second adjusting rod 28 near the third positioning block 22. The slider 29 is slidably connected to the sleeve 25. A fourth positioning block 30 is installed on the upper part of the slider 29. The fourth positioning block 30 can slide horizontally along the upper part of the second opening 27. A first connecting plate 31 and a second connecting plate 32 are respectively hinged on the fourth positioning block 30. The end of the first connecting plate 31 away from the fourth positioning block 30 is hinged to the vertical rod 23, and the end of the second connecting plate 32 away from the fourth positioning block 30 is hinged to another vertical rod 23.

[0036] In the specific implementation process, after the first guide block 6 and the second guide block 7 on the conveyor belt 5 have been worn for a certain period of time, the width will shrink. Or, if the size of the first guide block 6 and the second guide block 7 at the bottom of the new version of the conveyor belt 5 has changed, the width distance between the first alignment mechanism 9 and the second alignment mechanism 10 can be adjusted by the width adjustment part. During adjustment, the distance between the first constraint plate 11 and the second constraint plate 12 can be changed by rotating the second adjustment rod 28 clockwise or counterclockwise. The rotation of the second adjustment rod 28 can drive the slider 29 and the fourth positioning block 30 to slide along the sleeve 25. The sliding of the fourth positioning block 30 drives the first connecting plate 31 and the second connecting plate 32 to move respectively, thereby driving the vertical rod 23 to slide along the slide on the third positioning block 22, thereby realizing the adjustment of the width distance.

[0037] The above description is merely an embodiment of this utility model, and common knowledge such as specific structures and characteristics of the solution is not described in detail here. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these should also be considered within the protection scope of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
