Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper conveying, in particular to an automatic cleaning corrugated paperboard conveyor. Background Art

[0002] Corrugated paper boxes refer to corrugated paperboards that have been die-cut, crimped, nailed or glued to form corrugated paper boxes. Corrugated paper boxes are the most widely used packaging products, and their usage has always been the highest among all packaging products. Corrugated paper boxes need to be transported by automatic conveyors during production and transportation. For example, the existing CN202223425284.8, a cutting device for corrugated paper packaging, drives the rotating shaft and the cleaning fan to rotate through a rotating motor to clean the dust on the surface of the conveyor belt to prevent excessive dust from causing the corrugated paper box to deviate when being transported on the surface of the conveyor belt.

[0003] In similar schemes as mentioned above, paper scraps generated during the corrugated paper cutting process fall above the conveying device, causing the surface of the conveying device to be untidy, causing the corrugated paper to slide and fall during transportation, and when the corrugated paper falls from the previous process to the receiving platform, there is a certain randomness in the falling position, which is not convenient for unloading, and the height of the cleaning component cannot be adjusted. When the corrugated paper is piled up thickly, it will hinder the transmission of the conveyor belt and cause it to be stuck on one side of the cleaning component. For this reason, we propose an automatic cleaning corrugated cardboard conveyor. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an automatically cleaning corrugated cardboard conveyor, which solves the above-mentioned similar solutions proposed in the above-mentioned background technology. The paper scraps generated during the corrugated paper cutting process fall on the top of the conveying device, resulting in an untidy surface of the conveying device, causing the corrugated paper to slide and tip over during transportation, and when the corrugated paper falls from the previous process to the receiving platform, there is a certain randomness in the falling position, which is not convenient for unloading, and the height of the cleaning component cannot be adjusted. When the corrugated paper is piled up thickly, it will hinder the transmission of the conveyor belt and cause it to be stuck on one side of the cleaning component.

[0006] Furthermore, two groups of main rotating drums are arranged inside the upper and lower ends of the conveyor belt, and a plurality of groups of auxiliary rotating drums are arranged equidistantly between the two groups of main rotating drums.

[0007] Furthermore, the limiting components are symmetrically arranged in two groups about the vertical center line of the conveyor belt, and the angle between the first guide plate and the second guide plate is 160°.

[0008] Furthermore, a gap is provided between the first guide plate, the second guide plate and the conveyor belt.

[0009] Furthermore, a plurality of groups of rectangular grooves are provided through the lower portion of the placing platform, and two groups of limiting plates are symmetrically provided on the left and right sides of the placing platform.

[0010] Furthermore, the brush and the connecting block form a rotating structure with the telescopic rod through the rotating shaft.

[0011] The utility model provides an automatic cleaning corrugated cardboard conveyor, which has the following beneficial effects:

[0012] It can clean the paper scraps that fall on the top of the conveying device to avoid the untidy surface of the conveying device, which may cause the corrugated paper to slide and fall during transportation. It can also control the falling position of the corrugated paper to facilitate forklift transfer. It can also adjust the height of the cleaning component to prevent the height of the corrugated paper from being too high, which may hinder the transportation of the cardboard and cause the conveying device to jam. The specific contents are as follows:

[0013] The cleaning component is above the conveyor belt. When the main drum drives the conveyor belt to rotate, the brush rubs on the surface of the conveyor belt to remove paper scraps on the surface of the conveyor belt. The limiting component guides the holding table to the position before unloading, and the rectangular groove under the holding table is convenient for forklifts to insert, thereby facilitating unloading. The telescopic rod drives the brush to clean the top of the corrugated paper, and the brush is rotated to rotate 90° along the shaft to avoid getting stuck in the corrugated paper.

DETAILED DESCRIPTION

[0019] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0020] like Figures 1 to 4As shown, the utility model provides a technical solution: an automatic cleaning corrugated cardboard conveyor, including a conveyor belt 1, a limiting component 5 and a cleaning component 7, two groups of main rotating drums 2 are arranged on the inner sides of the upper and lower ends of the conveyor belt 1, and a plurality of groups of auxiliary rotating drums 3 are arranged equidistantly between the two groups of main rotating drums 2, and the stability of the device is strengthened by the auxiliary rotating shaft, a holding platform 6 is arranged on the outer side of the conveyor belt 1, and the limiting component 5 is located on the outer side of the conveyor belt 1, the limiting component 5 includes a first guide plate 501, a second guide plate 502 and a limiting block 503, and a first guide plate 501 is arranged above the holding platform 6, the upper end of the first guide plate 501 is connected to the second guide plate 502, and the first guide plate 501 is connected to the second guide plate 502. Limit blocks 503 are fixedly provided on the outer sides of the first guide plate 501 and the second guide plate 502, which are used to control the falling position of the corrugated paper to prevent the corrugated paper from being randomly discharged and inconvenient to exchange with the next program. Because the limit assembly 5 is symmetrical with respect to the vertical center line of the conveyor belt 1, and the angle between the first guide plate 501 and the second guide plate 502 is 160°, it is convenient to adjust the corrugated paper located at the edge along the first guide plate 501 to the center position of the conveyor belt 1. Because a gap is set between the first guide plate 501, the second guide plate 502 and the conveyor belt 1, friction between the limit assembly 5 and the conveyor belt 1 can be avoided, thereby shortening the service life of the conveyor belt 1.

[0021] Support plates 4 are provided on the left and right sides of the conveyor belt 1, and the cleaning component 7 is located below the placing platform 6. A plurality of groups of rectangular grooves 62 are provided below the placing platform 6. The rectangular grooves 62 are provided to facilitate the insertion of a forklift into the bottom of the placing platform 6, so as to facilitate forklift transportation. Two groups of limiting plates 61 are symmetrically provided on the left and right sides of the placing platform 6. The limiting plates 61 are used to fix the corrugated cardboard to prevent the corrugated cardboard from deflecting and tipping over during transportation. The cleaning component 7 includes a brush 701, a connecting block 702, a telescopic rod 703 and a rotating shaft 704. A telescopic rod 703 is provided on the right side of the support plate 4, and the upper end of the telescopic rod 703 is connected to the rotating shaft 704. A connecting block 702 is welded to the upper end, and a brush 701 is provided on the outer side of the conveyor belt 1. The friction between the brush 701 and the conveyor belt 1 can blow off the paper scraps and dust on the surface of the conveyor belt 1, thereby cleaning the conveyor belt and preventing the corrugated cardboard from sliding and tipping over during transportation. Because the brush 701 and the connecting block 702 form a rotating structure through the rotating shaft 704 and the telescopic rod 703, the brush 701 can be rotated to 90° along the rotating shaft 704, thereby not hindering the normal transportation of the corrugated paper, and the telescopic rod 703 can be extended and retracted up and down to make the brush 701 move upward, which is beneficial to sweeping off the dust on the upper surface of the corrugated paper.

[0022] In summary, when the automatic cleaning corrugated cardboard conveyor is in use, the rotating shaft 704 is rotated to make the bottom of the brush 701 contact with the surface of the conveyor belt 1. When in use, the motor is started, the motor drives the main rotating drum 2 to rotate, the main rotating drum 2 drives the conveyor belt 1 and the multiple sets of auxiliary rotating drums 3 to rotate, and the corrugated cardboard is placed on the upper part of the placing table 6. The corrugated cardboard is clamped by the limiting plate 61, and the placing table 6 is driven by the conveyor belt 1 to move linearly. When the corrugated paper is thin, the corrugated paper passes through the cleaning component 7, and the telescopic rod 703 is extended upward to drive the brush 701 to move. The brush 701 moves upward, and the brush 701 sweeps away the paper scraps and dust above the corrugated paper. When the corrugated paper is thick, the brush 701 is rotated 90 degrees along the rotating shaft 704 so that the corrugated paper passes through the cleaning component 7, and then the brush 701 turns back to continue cleaning the conveyor belt 1. The corrugated paperboard slides along the first guide plate 501 to between the two sets of second guide plates 502. At this time, one side of the placing table 6 is arranged parallel to the upper end of the conveyor belt, and is inserted into the rectangular groove 62 through the fork frame of the forklift, so that the corrugated paperboard can enter the next procedure conveniently.
