Description

Technical Field

[0001] The present invention specifically relates to a waste edge collecting and cleaning system and method for paper production. Background Art

[0002] In the processing of paper products, in order to ensure the continuity of production, long strips of paper are usually used as raw materials, and the paper rolls are transported by rollers. During the transportation process, the raw materials are cut and other processing steps are completed. Since the cutting of paper is to adjust the width of the paper, a certain amount of waste will be cut out on both sides of the paper width direction during the cutting process. At present, the waste generated by cutting paper will be collected in the waste box, but the paper waste is relatively loose, so it takes up more collection space, which makes the collection space easy to fill up and requires frequent replacement and cleaning of the waste box. Therefore, a waste edge collection and cleaning system and method for paper production is proposed to solve this problem. Summary of the invention

[0003] The purpose of the present invention is to provide a waste edge collection and cleaning system and method for paper production in view of the deficiencies in the prior art, which can well solve the above-mentioned problems.

[0005] A method for collecting and cleaning waste edges for paper production is provided, comprising the following steps:

[0006] S1: The paper is transported on the conveyor belt in the paper production process, and is cut by the paper cutter during the process, resulting in paper waste edges. The paper waste edges enter the feed cavity through the top of the feed plate under the suction action of the second suction pump;

[0007] S2: The paper waste edges fall onto the rotating cutting blade driven by the main shredding motor through the spiral feeding channel for cutting, and then fall into the cylindrical cavity. The receiving motor in the cylindrical cavity drives the arc-shaped shovel plate to rotate, and the shredded paper waste edges are scraped into the pressing cavity;

[0008] S3: The air inlet end of the second air suction pump arranged inside the first air suction cavity at the bottom of the cylindrical cavity extends into the first air suction cavity. An arc-shaped air permeable plate is provided between the first air suction cavity and the cylindrical cavity to play a ventilation role. After the shredded paper waste edges are scraped into the pressing cavity, the pressing motor drives the pressing plate to move and press the paper waste edges tightly.

[0009] S4: The bottom of the pressing chamber is an air-permeable plate arranged obliquely to ensure that the compressed paper waste edge is always located obliquely below the pressing chamber, and a second suction cavity is arranged at the bottom of the pressing chamber, and an air-permeable plate is arranged between the second suction cavity and the pressing chamber, and the first suction pump sucks air into the second suction cavity;

[0010] S5: After the top of the pressing plate contacts the inclined top end surface of the pressing chamber, the spring is pressed tightly, and the square outer frame moves downward as a whole, so that the overall height of the pressing plate can be shortened, and the pressing can continue to move forward to complete the pressing;

[0011] S6: The power of the second suction pump and the first suction pump is dynamically adjusted. The light bar shines downward, and the light passes through the light-transmitting holes on the feed plate and hits at least ten uniformly arranged brightness sensors. When there are many paper waste edges on the feed plate, more light-transmitting holes are blocked by the paper waste edges. At this time, the total light that the brightness sensor can receive becomes less, and the power of the second suction pump and the first suction pump is increased, thereby accelerating the speed of sucking the paper waste edges;

[0012] Similarly, when there are fewer paper waste edges on the feed plate, the paper waste edges block fewer light holes. At this time, the total light that the brightness sensor can receive increases. At this time, the power of the second air pump and the first air pump is reduced. Here, the two air pumps are set to the same power.

[0013] The advantages of the waste edge collection and cleaning system and method for paper production are as follows:

[0014] By setting a spiral feeding channel, a main crushing motor and a cutting blade in the feeding chamber, the waste edges with a larger area can be crushed for easy storage, avoiding the entanglement of long waste edges. By setting a pressing chamber, a first suction pump, a breathable plate, a pressing plate, a base and a pressing motor, the waste edges inside the pressing chamber can be compressed to prevent the waste from remaining loose and occupying too much collection space. At the same time, by setting a square outer frame, a spring, a square bearing groove, a square plate, a first limit block and a second limit block on the pressing plate, the overall height of the pressing plate can be changed according to the inclination angle of the top end face of the pressing chamber during the process of pushing into the pressing chamber. This structure can compress the waste edges more tightly. At the same time, the system adopts dynamic adjustment of the power of the suction component, which can ensure a good waste collection effect while avoiding energy waste caused by long-term high power.

[0025] According to one embodiment of the present application, a base 20 is provided at the bottom of the first suction chamber of the waste edge collection and cleaning system for paper production, and a pressing motor 21 is provided inside the base 20. A pressing plate 19 is connected to the output end of the pressing motor 21, and the pressing plate 19 includes a square plate 32 and a square outer frame 29 sleeved on the outside of the square plate 32. A square bearing groove 31 for inserting the square plate 32 is provided at the bottom of the square outer frame 29. Springs 30 are evenly provided between the top of the square plate 32 and the upper end surface inside the square outer frame 29.

[0026] According to one embodiment of the present application, the collecting motor 12 of the paper production waste collection and cleaning system is arranged at the center of the inner side wall of the cylindrical cavity 11.

[0027] According to one embodiment of the present application, an outward opening door 15 is provided on the top end surface of the pressing chamber 16 of the paper production waste collection and cleaning system, and the outward opening door 15 is connected to the top end surface of the pressing chamber 16 through a lower rotating shaft 14.

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

[0029] According to an embodiment of the present application, the top end surface of the square outer frame 29 of the paper production waste collection and cleaning system is an inclined structure, and its inclination angle is the same as the inclination angle of the top end surface of the pressing chamber 16.

[0030] According to an embodiment of the present application, the first suction pump 17 and the second suction pump 22 of the paper production waste collection and cleaning system are electric suction pumps with adjustable power.

[0031] According to one embodiment of the present application, when the paper production waste edge collection and cleaning system is in use, the paper 24 is transported on the paper production link material conveyor belt 27, and is cut by the paper cutter 26 during the process to produce paper waste edges 25. The paper waste edges 25 enter the feed cavity 7 through the top of the feed plate 4 under the suction action of the second suction pump 22, and then the paper waste edges 25 pass through the spiral feed channel 8 and fall on the rotating cutting blade 10 driven by the main shredding motor 9 for cutting, and then fall into the cylindrical cavity 11 (the setting of the spiral feed channel 8 can play a role in extending the channel, thereby preventing the paper scraps generated after being cut by the cutting blade 10 from flying out from the suction channel 3 again). The receiving motor 12 in the cylindrical cavity 11 drives the arc-shaped scraping plate 13 to rotate, and scrapes the shredded paper waste 25 into the pressing cavity 16. The air inlet end of the second suction pump 22 arranged inside the first suction cavity at the bottom of the cylindrical cavity 11 extends into the first suction cavity. The arc-shaped air permeable plate 23 is provided between the first suction cavity and the cylindrical cavity 11 to play a ventilation role. After the shredded paper waste 25 is scraped into the pressing cavity 16, the pressing motor 21 will drive the pressing plate 19 to move and press the paper waste 25 The pressing chamber 16 is tight, and the bottom of the pressing chamber 16 is an inclined air permeable plate 18, so that the compressed paper waste edge 25 is always located at an oblique lower part of the pressing chamber 16, and a second suction cavity is arranged at the bottom of the pressing chamber 16, and the air permeable plate 18 is arranged between the second suction cavity and the pressing chamber 16. The first suction pump 17 sucks air into the second suction cavity, and the air permeable holes evenly arranged on the air permeable plate 18 can ensure that the compressed paper waste edge 25 will only block part of the air permeable holes, so that it will not affect the overall suction effect of the first suction pump 17. The moving direction of the output end of the pressing motor 21 is parallel to the air-permeable plate 18, which can 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 inclined top end surface of the pressing chamber 16, the spring 30 is tightened, and the square outer frame 29 moves downward as a whole, so that the overall height of the pressing plate 19 is shortened, and the pressing can continue to be completed; at the same time, the power of the second suction pump 22 and the first suction pump 17 will be dynamically adjusted, and the light bar 1 will shine downward, and the light will pass through the light-transmitting holes on the feed plate 4 and hit at least ten evenly arranged brightness sensors. When the paper on the feed plate 4 When there are more waste edges 25, more light-transmitting holes are blocked by the waste edges 25 of the paper. At this time, the total light that the brightness sensor can receive becomes less. At this time, the power of the second suction pump 22 and the first suction pump 17 is increased to speed up the speed of sucking in the waste edges 25 of the paper. Similarly, when there are fewer waste edges 25 of the paper on the feeding plate 4, fewer light-transmitting holes are blocked by the waste edges 25 of the paper. At this time, the total light that the brightness sensor can receive becomes more. At this time, the power of the second suction pump 22 and the first suction pump 17 is reduced. This dynamic adjustment process can ensure a good waste collection effect while avoiding energy waste caused by long-term high power.

[0032] The specific calculation method of the suction power of the second suction pump and the first suction pump is as follows:

[0047] According to one embodiment of the present application, the waste edge collection and cleaning system for paper production can crush waste edges with a larger area for easy storage by setting a spiral feeding channel 8, a main crushing motor 9 and a cutting blade 10 in the feeding chamber 7, thereby avoiding the entanglement of long waste edges. The waste edges inside the pressing chamber 16 can be compressed by setting a pressing chamber 16, a first air suction pump 17, a breathable plate 18, a pressing plate 19, a base 20 and a pressing motor 21 to prevent the waste from remaining loose and occupying too much collection space. At the same time, by setting a square outer frame 29, a spring 30, a square bearing groove 31, a square plate 32, a first limit block 33 and a second limit 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 chamber 16 during the process of pushing it into the pressing chamber 16. This structure can compress the waste edges more tightly.

It should be pointed out that, for a person skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
