Description

Technical Field

[0001] The utility model belongs to the technical field of corrugated paper processing, and particularly relates to a corrugated paper pressing mechanism. Background Technique

[0002] Corrugated paper is a plate-like object formed by bonding a facing paper and a corrugated paper with a waveform formed by processing through a corrugating roll. It is generally divided into two categories: single corrugated cardboard and double corrugated cardboard, and is divided into five types according to the size of the corrugation: A, B, C, E, and F. The invention and application of corrugated paper have a history of more than one hundred years. It has the advantages of low cost, light weight, easy processing, high strength, excellent printing adaptability, convenient storage and handling, etc. More than 80% of corrugated paper can be recycled. Corrugated paper can be used as packaging for food or digital products, which is relatively environmentally friendly and widely used; when corrugated paper is used, it often needs to be further processed to meet the packaging requirements. At this time, a pressing mechanism is required to press the corrugated paper to ensure the smooth progress of processing.

[0003] Comparing with the Chinese patent with the authorization announcement number of CN219404488U, it discloses a corrugated paper pressing mechanism, including a workbench, the top of the workbench is fixedly connected with a top plate through a plurality of fixed rods, the bottom of the top plate is fixedly connected with a cutting machine body, connection mechanisms are arranged on both sides of the cutting machine body, a movable rod is arranged at the bottom of the connection mechanism, the bottom of the movable rod is fixedly connected with a pressing ring surrounding the cutting machine body, and a rolling mechanism is arranged at the bottom of the pressing ring.

[0004] As the cutting depth increases in the above patent, the pressure on the corrugated paper also gradually increases. Although the increase in pressure improves the fixing effect, when the cutting depth is too large, it will cause excessive pressure and produce indentations on the surface of the corrugated paper. Therefore, a new device needs to be designed. Content of the Utility Model

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-4 , a corrugated paper pressing mechanism, including a cutting device for cutting corrugated paper, and further including pressure relief components symmetrically installed on the front and rear sides of the cutting device for upward sliding after overpressure deformation and tripping, and a roll pressing component installed at the bottom of the pressure relief component for rolling and pressing the corrugated paper and performing elastic buffering.

[0026] In this embodiment: The cutting device includes a workbench 101, a linear guide rail 102 is installed on the workbench 101, a linear motor 103 is slidably installed on the linear guide rail 102, an electric push rod 104 is arranged below the linear motor 103, a fixing bracket 105 is arranged below the electric push rod 104, a cutting machine 106 is arranged at the bottom of the fixing bracket 105, and the cutting machine 106 is bolted to the fixing bracket 105. The corrugated paper board is placed on the workbench 101, the electric push rod 104 extends to drive the cutting machine 106 at the bottom of the fixing bracket 105 to move downward to cut the corrugated paper downward, and then the linear motor 103 drives the cutting machine 106 along the linear guide rail 102 through the fixing bracket 105 to perform transverse cutting on the corrugated paper;

[0027] In this embodiment, the pressure relief component includes a fixed block 201. A sliding sleeve 202 is installed below the fixed block 201. Twelve card slots 203 are symmetrically arranged on both sides inside the sliding sleeve 202. A sliding rod 204 is slidably installed at the bottom of the sliding sleeve 202. A limiting plate 205 is arranged at the middle position of the sliding rod 204. Two mounting plates 206 are symmetrically arranged on both sides above the limiting plate 205. Elastic plates 207 are arranged on the opposite sides of the two mounting plates 206. The elastic plates 207 are inclined upward from the position of the mounting plates 206, and the end far away from the mounting plates 206 is snapped into the lowermost card slot 203. The sliding rod 204 is a square rod. The limiting plate 205 and the sliding rod 204 are integrally formed. The elastic plates 207 are made of 65Mn material, and the elastic plates 207 are welded to the mounting plates 206. As the cutting depth increases, the pressure of the rolling component 3 on the corrugated board will also increase. When the pressure is too high, the reaction force transmitted by the rolling component 3 to the sliding rod 204 will cause the sliding rod 204 to drive the two side mounting plates 206 to slide upward along the inside of the sliding sleeve 202 below the fixed block 201 under the restriction of the limiting plate 205, causing the elastic plates 207 to bend and deform, disengaging from the current card slot 203 and snapping into the adjacent upper card slot 203 to achieve pressure relief;

[0028] In this embodiment, the rolling component includes a lifting frame 301. A buffer plate 302 is installed below the lifting frame 301. A pressing plate 305 is arranged below the buffer plate 302. Nine pressing rollers 306 are evenly arranged at the bottom of the pressing plate 305. Three limiting rods 303 are evenly arranged between the pressing plate 305 and the buffer plate 302. Springs 304 are installed outside the limiting rods 303. The lifting frame 301 is in the shape of an 'n'. When cutting downward, the fixed frame 105 causes the two side pressure relief components 2 to drive the pressing rollers 306 at the bottom of the rolling component 3 to tightly press the front and rear sides of the cutting position of the corrugated board, and the pressing rollers 306 can drive the pressing plate 305 to squeeze the springs 304 along the limiting rods 303, providing buffering for the pressing under the support of the buffer plate 302 below the lifting frame 301.

[0029] Working principle: Place the corrugated cardboard on the workbench 101. The electric push rod 104 extends to drive the cutting machine 106 at the bottom of the fixing frame 105 to move downward to cut the corrugated paper downward. Subsequently, the linear motor 103 drives the cutting machine 106 to move along the linear guide rail 102 through the fixing frame 105 to perform a transverse cut on the corrugated paper. During the downward cutting, the fixing frame 105 causes the pressure relief components 2 on both sides to drive the pressure rollers 306 at the bottom of the roller pressing component 3 to tightly press the front and rear sides of the cutting position of the corrugated cardboard. Moreover, the pressure roller 306 can drive the pressing plate 305 to squeeze the spring 304 along the limiting rod 303, providing buffering for the pressing under the support of the buffer plate 302. As the cutting depth increases, the pressure of the roller pressing component 3 on the corrugated cardboard will also increase. When the pressure is too high, the reaction force transmitted by the roller pressing component 3 to the sliding rod 204 through the lifting frame 301 will cause the sliding rod 204 to drive the mounting plates 206 on both sides to slide upward along the inside of the sliding sleeve 202 under the fixing block 201 under the limitation of the limiting plate 205, causing the elastic plate 207 to bend and deform, disengaging from the current card slot 203 and engaging into the adjacent upper card slot 203 to achieve pressure relief.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
