[0027] According to one embodiment of the present application, the top end face of the pressing cavity 16 of the paper edge collection system is provided with an outward opening door 15 connected with the top end face of the pressing cavity 16 through a lower rotating shaft 14.

[0028] According to one embodiment of the present application, the travel direction of the output end of the pressing motor 21 of the paper edge collection system is parallel to the air permeable plate 18.

[0029] According to one embodiment of the present application, the top end face of the square outer frame 29 of the paper edge collection system is an inclined structure, and the inclination angle is the same as that of the top end face of the pressing cavity 16.

[0030] According to one embodiment of the present application, the first suction pump 17 and the second suction pump 22 of the paper edge collection system are power-adjustable electric suction pumps.

[0031] According to one embodiment of the present application, when the paper edge collection system is used, the paper 24 is conveyed on the paper conveying belt 27 in the paper production link, and is cut by the paper cutting machine 26 to generate paper waste edge 25, the paper waste edge 25 enters the feeding cavity 7 through the upper part of the feeding plate 4 under the action of the suction of the second suction pump 22, and the two rotating rotating brushes 35 wind the paper waste edge 25 from between the two rotating rotating brushes 35, so that the feeding of the paper waste edge 25 can be accelerated, and the flying of paper scraps can be prevented to a certain extent.

[0032] After the paper waste edge 25 falls on the rotating cutting blade 10 driven by the main crushing motor 9 for cutting, and then the paper waste edge 25 falls down again to be shredded by the two auxiliary stirring fans 37, the two auxiliary stirring fans 37 inclined at 45 degrees and the horizontally arranged cutting blade 10 can form different angle cutting to further improve the cutting efficiency

[0033] After falling into the cylindrical cavity 11 (the spiral feeding channel 8 can extend the channel to avoid the paper scraps produced after being cut by the cutting blade 10 from flying out from the suction channel 3 again). The material scraping motor 12 in the cylindrical cavity 11 drives the arc-shaped material scraping plate 13 to rotate and scrape the crushed paper waste edge 25 into the pressing cavity 16. The air inlet end of the second air suction pump 22 arranged in the first air suction cavity at the bottom of the cylindrical cavity 11 extends into the first air suction cavity. The first air suction cavity and the cylindrical cavity 11 are connected by the arc-shaped air permeable plate 23 for air permeation. After the crushed paper waste edge 25 is scraped into the pressing cavity 16, the pressing motor 21 drives the pressing plate 19 to move and press the paper waste edge 25. The bottom of the pressing cavity 16 is provided with the air permeable plate 18 arranged obliquely. In this way, the paper waste edge 25 pressed can always be below the oblique bottom of the pressing cavity 16. The second air suction cavity is arranged at the bottom of the pressing cavity 16. The second air suction cavity and the pressing cavity 16 are connected by the air permeable plate 18. The first air suction pump 17 sucks air from the second air suction cavity. The air permeable holes uniformly arranged on the air permeable plate 18 can ensure that the paper waste edge 25 pressed can only block part of the air permeable holes, so as not to affect the overall air suction effect of the first air suction pump 17. The moving direction of the output end of the pressing motor 21 is parallel to the air permeable plate 18, so as to ensure that the bottom of the pressing plate 19 is always close to the air permeable plate 18. When the top of the pressing plate 19 contacts the top end surface of the oblique top of the pressing cavity 16, the spring 30 is compressed, and the square outer frame 29 moves downward as a whole. In this way, the overall height of the pressing plate 19 is shortened, and the pressing can be continued. At the same time, the power of the second air suction pump 22 and the first air suction pump 17 is dynamically adjusted. The light bar 1 downwardly emits light, and the light passes through the light transmission holes on the feeding plate 4 and hits the at least ten brightness sensors arranged uniformly. When the paper waste edge 25 on the feeding plate 4 is more, the paper waste edge 25 blocks more light transmission holes. At this time, the total light that the brightness sensor can receive is less. At this time, the power of the second air suction pump 22 and the first air suction pump 17 is increased, so as to speed up the speed of sucking the paper waste edge 25. Similarly, when the paper waste edge 25 on the feeding plate 4 is less, the paper waste edge 25 blocks less light transmission holes. At this time, the total light that the brightness sensor can receive is more. At this time, the power of the second air suction pump 22 and the first air suction pump 17 is reduced. This dynamic adjustment process can ensure good waste collection effect while avoiding energy waste caused by long-term high power.

[0034] The calculation of the suction power of the second suction pump and the first suction pump is as follows:

[0035]

[0036] Wherein:

[0037] P adj : suction power;

[0038] L tot : total brightness;

[0039] M is the number of brightness sensors, M > 10;

[0040] B j : the brightness value detected by the jth brightness sensor, j = 1, 2,..., M;

[0041] P0: basic suction power;

[0042] a, b: proportional constant, used to adjust the nonlinear relationship between suction power and total brightness;

[0043] P lim : maximum power of the suction component;

[0044] a, b: base of natural logarithm;

[0045] γ: adjustment factor, controls the shape of the power growth curve;

[0046] L norm : normalized brightness value, used to prevent the value within the function from being too small or too large;

[0047] L max : expected maximum total brightness value.

[0048] According to one embodiment of the present application, the paper edge collection system convenient to compress can crush the larger area of waste edge to facilitate storage by setting the spiral feeding channel 8, the main crushing motor 9 and the cutting blade 10 in the feeding cavity 7, avoid the situation of long waste edge entanglement, by setting the pressing cavity 16, the first suction pump 17, the air permeable plate 18, the pressing plate 19, the base 20 and the pressing motor 21 can compress the waste edge inside the pressing cavity 16, prevent waste from occupying too much collection space while keeping loose, at the same time, by setting the square frame 29, the spring 30, the square bearing groove 31, the square plate 32, the first limiting block 33 and the second limiting block 34 on the pressing plate 19, the overall height of the pressing plate 19 can change according to the inclination angle of the top end face of the pressing cavity 16 during the process of pushing into the pressing cavity 16, this structure can compress the waste edge more tightly.

[0049] The above described embodiments only represent several implementation manners of the present application, which are described in a more specific and detailed manner, but should not be understood as a limitation on the scope of the present application. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the claims.
