Technical Field
[0001] The utility model relates to the technical field of paper cutting, in particular to a paper cutting device capable of removing burrs. Background Art
[0002] In the printing industry, paper cutting is an extremely crucial process. Whether it is books, magazines, promotional posters or various commercial printed materials, after printing, they need to be accurately cut to the specified size to ensure the neatness and beauty of the products and facilitate subsequent binding, packaging and other processes. With the development of the printing industry, the requirements for the accuracy, efficiency and quality of paper cutting are constantly increasing. In some art picture albums and limited edition books, not only the size of the paper cutting is required to be accurate, but also the cutting edge is required to be smooth to avoid affecting the texture of the printed matter.
[0003] Traditional paper cutting operations rely on manual alignment of paper in many cases. Operators observe and manually adjust by eye to align the edges of the paper. The method of manually aligning paper is difficult to meet the requirements of high-speed production, seriously restricting the improvement of production efficiency. The visual error of people and the instability of manual operation will cause the edges of the paper to be slightly uneven. When these papers with alignment errors enter the cutting process, it is easy to produce rough edges, resulting in burrs or unevenness on the edges of the cut paper, affecting the appearance quality of the printed matter. In view of the above problems, a paper cutting device capable of removing burrs is proposed. Summary of the Utility Model
[0004] The purpose of the utility model is to make up for the deficiencies of the prior art and provide a paper cutting device capable of removing burrs.

[0007] As described above, the bottom ends on both sides of the alignment plate are slidably connected to the inner wall of the chute. The alignment plate and the chute form a sliding structure through a telescopic spring. The alignment plates are symmetrically distributed on both sides of the top of the feeding table.
[0008] As described above, one end of the outer surface of the feeding table is fixedly connected with a cutting plate. A cutting groove is formed on the outer side of one side of the cutting plate. A placement rack is fixedly connected to the outer surface of the other side of the cutting plate. The cutting plate is respectively fixed between the feeding table and the placement rack. A hydraulic rod is fixedly connected to the top of the placement rack. A cutting blade is fixedly connected to the outer wall of the bottom end of the hydraulic rod. Placement columns are arranged on both sides of the cutting plate. The placement columns are fixed to the outer wall of the top of the processing table. A guiding groove is formed on the opposite side of a group of the placement columns. A bottom column is fixedly connected to the inner part of the bottom end of the placement column. A return spring is fixedly connected to the top of the bottom column. A pressing plate is fixedly connected to the outer wall of one side of the return spring.
[0009] As described above, the outer surface of the pressing plate and the cutting groove are on the same vertical center line. The cutting blade is arranged directly above the cutting groove. The outer surface of the pressing plate is in close contact with the outer surface of the cutting blade. The cutting blade and the cutting groove form a lifting structure through the hydraulic rod.
[0010] As described above, the pressing plate and the hydraulic rod form a lifting structure through the return spring. The lowest point of the guiding groove and the top surface of the cutting plate are arranged on the same horizontal plane.

[0012] Compared with the prior art, the paper cutting device capable of removing burrs has the following beneficial effects:
[0013] First, through the combination of the cylinder pushing the push plate and the cam driving the alignment plate, the present utility model realizes the automation of paper alignment, greatly reducing the labor input and operation time. In the case of a large number of papers to be cut, the rotation of the cam drives the alignment plate to reciprocate along the chute, pushing and flattening both sides of the paper stack. With the assistance of the telescopic spring, the alignment plate can push and flatten each time it contacts the paper stack, ensuring the precise alignment of the paper edges, ensuring that the paper edge straightness is within a very small tolerance range, improving the quality of the cut paper, and reducing the scrap rate caused by rough edges, thereby achieving the effect of removing burrs.
[0014] Second, under the action of the return spring, the pressing plate of the present utility model can automatically adjust its position according to the actual height of the paper stack. When the paper stack is relatively high, the pressing plate will come into contact with the paper earlier during the descending process, and the return spring is compressed to a greater extent. When the paper stack is relatively short, the pressing plate can continue to descend until it is in close contact with the top of the paper stack, and the return spring is compressed less. This kind of self-adaptive ability ensures that no matter how the height of the paper stack changes, it can be stably and evenly pressed, preventing the paper from moving or warping during the cutting process, enabling the cutting blade to closely fit the outer wall of the paper during cutting, reducing the gap between the blade and the paper during cutting, avoiding the paper from being pulled or torn during cutting due to too large a gap, and thus effectively reducing the generation of burrs.
[0015] Other advantages, objectives and features of the present utility model will be described to some extent in the subsequent description, and to some extent, will be obvious to those skilled in the art based on the study of the following text, or can be taught from the practice of the present utility model.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] like Figures 1-4 As shown, the utility model provides a technical solution: a paper cutting device capable of removing burrs comprises a processing table 1, a feeding table 101 is fixedly connected to the outer surface of the top of the processing table 1, a fixing seat 102 is fixedly connected to both sides of one end of the feeding table 101, a cylinder 2 is fixedly connected to the outside of the top of the feeding table 101, a push plate 201 is fixedly connected to the outer wall of one side of the cylinder 2, a placement groove 202 is provided on the top of the fixing seat 102, a driving motor 203 is fixedly connected to the inner surface of the placement groove 202, a cam 204 is movably connected to the outer surface of the top of the driving motor 203, slide grooves 205 are provided on both sides of the cam 204, the slide grooves 205 penetrate and are opened on the top of the fixing seat 102 and the feeding table 101, a telescopic spring 206 is fixedly connected to the inner surface of the slide groove 205, and the outer side of the telescopic spring 206 is fixedly connected There is an alignment plate 207, and a cutting plate 3 is fixedly connected to the outer surface of one end of the feeding table 101, a cutting groove 301 is opened on the outside of one side of the cutting plate 3, and a placement rack 302 is fixedly connected to the outer surface of the other side of the cutting plate 3. The cutting plates 3 are respectively fixed between the feeding table 101 and the placement rack 302, and a hydraulic rod 303 is fixedly connected to the top of the placement rack 302, and a cutting blade 304 is fixedly connected to the outer wall of the bottom end of the hydraulic rod 303. Placement columns 305 are arranged on both sides of the cutting plate 3, and the placement columns 305 are fixed to the top outer wall of the processing table 1. A group of placement columns 305 are opened on the opposite side with a guide groove 306, and a bottom column 307 is fixedly connected to the bottom of the placement column 305, and a reset spring 308 is fixedly connected to the top of the bottom column 307, and a holding plate 309 is fixedly connected to the outer wall of one side of the reset spring 308.
[0023] According to the overall structure of the device, when the device is in use, the staff places the paper to be cut on one side of the feeding table 101 close to the cylinder 2. At the same time, the cylinder 2 pushes the push plate 201 to push the paper towards the cutting plate 3. While pushing, the surface of the push plate 201 that fits the paper is made as flat as possible. When the paper stack passes through the front end of the feeding table 101, the driving motor 203 is started at this time, and the driving motor 203 drives the cam 204 to start rotating. When the cam 204 rotates, the top will touch the outer alignment plate 207. The alignment plate 207 makes a reciprocating movement towards the inside of the feeding table 101 under the push of the cam 204. The alignment plate 207 moves closer to the feeding table 101 along the sliding groove 205. When the alignment plate 207 reciprocally touches the paper stack on the top of the feeding table 101, the two sides of the paper stack are continuously pushed flat. When the cam 204 rotates in the reverse direction and leaves the surface of the alignment plate 207, at this time, the alignment plate 207 retracts to its original position under the drive of the telescopic spring 206, and then fits the two sides of the paper stack again when the cam 204 rotates next time. Through the continuous push of the alignment plate 207, the paper stack to be cut is automatically leveled, and the edges of the paper are automatically aligned, thereby reducing the probability of the appearance of rough edges and achieving the effect of removing burrs. When the push plate 201 pushes the paper above the cutting plate 3, the staff determines that the paper reaches the position to be cut. At this time, the reset spring 308 drives the pressing plate 309 to be at the uppermost position of the guiding groove 306. At the same time, the limiting strip 401 at the top engages the extension plate 402 on the inner wall of the card slot 403, thereby limiting the pressing plate 309 in place. At this time, the limiting strip 401 is toggled to make the extension plate 402 leave the inner wall of the card slot 403. The reset spring 308 drives the pressing plate 309 to move downward due to its own spring self-contraction force. The pressing plate 309 starts to descend along the guiding groove 306 and stops descending when it touches the highest point of the paper stack. The pressing plate 309 is tightly limited at the high position of the paper stack through the reset spring 308, thereby completing the pressing work on the paper. At this time, the hydraulic rod 303 is started again to drive the cutting blade 304 to cut the paper stack. The pressing plate 309 enables the cutting blade 304 to closely fit on the outer wall during cutting, and the paper on the outer side of the pressing plate 309 is vertically cut. The evenly pressed paper can reduce the appearance of burrs during cutting.
[0024] As Figures 1-4 shown, the push plate 201 forms a sliding structure with the feeding table 101 through the cylinder 2. The outer wall of the bottom end of the push plate 201 is closely attached to the outer side of the top of the feeding table 101. The fixed seat 102 is arranged on the same horizontal plane as the feeding table 101, and the fixed seat 102 is closely attached to both sides of the feeding table 101. The cam 204 is rotatably connected to the top of the driving motor 203. The bottom ends of both sides of the alignment plate 207 are slidably connected to the inner wall of the sliding groove 205. The alignment plate 207 forms a sliding structure with the sliding groove 205 through the telescopic spring 206. The alignment plates 207 are symmetrically distributed on both sides of the top of the feeding table 101.
[0025] The staff places the paper to be cut on one side of the feeding table 101 close to the cylinder 2. At the same time, the cylinder 2 pushes the push plate 201 to push the paper towards the cutting plate 3. While pushing, the surface of the push plate 201 that fits the paper is made as flat as possible. When the paper stack passes the front end of the feeding table 101, the driving motor 203 is started at this time, and the driving motor 203 drives the cam 204 to start rotating. When the cam 204 rotates, the top will touch the outer alignment plate 207. The alignment plate 207 makes a reciprocating movement towards the inside of the feeding table 101 under the push of the cam 204. The alignment plate 207 moves closer to the feeding table 101 along the sliding groove 205. When the alignment plate 207 reciprocally touches the paper stack on the top of the feeding table 101, it continuously levels the two sides of the paper stack. When the cam 204 rotates in the reverse direction and leaves the surface of the alignment plate 207, at this time, the alignment plate 207 retracts to its original position under the drive of the telescopic spring 206, and then fits the two sides of the paper stack again when the cam 204 rotates next time. Through the continuous push of the alignment plate 207, the paper stack to be cut is automatically leveled, and the edges of the paper are automatically aligned, thereby reducing the probability of the appearance of rough edges and achieving the effect of removing burrs.
[0026] As Figures 1-4 As shown, the outer surface of the pressing plate 309 and the cutting groove 301 are on the same vertical center line. The cutting blade 304 is arranged directly above the cutting groove 301. The outer surface of the pressing plate 309 is in close contact with the outer surface of the cutting blade 304. The cutting blade 304 and the cutting groove 301 form a lifting structure through the hydraulic rod 303. The pressing plate 309 and the hydraulic rod 303 form a lifting structure through the return spring 308. The lowest part of the guiding groove 306 and the top surface of the cutting plate 3 are set at the same horizontal plane. The pressing plate 309 is horizontally arranged on the top of the cutting plate 3 and the cutting groove 301. The pressing plate 309 is slidably connected to the inner wall of the guiding groove 306.
[0027] Due to its own spring self - shrinking force, the return spring 308 drives the pressing plate 309 to move downward. The pressing plate 309 starts to descend along the guiding groove 306 and stops descending when it touches the highest part of the paper stack. The return spring 308 tightly limits the pressing plate 309 at the high position of the paper stack, thus completing the pressing work of the paper. At this time, the hydraulic rod 303 is started again, which drives the cutting blade 304 to cut the paper stack. The pressing plate 309 enables the cutting blade 304 to be in close contact with the outer wall during cutting, and vertically cuts the paper on the outer side of the pressing plate 309. The uniformly pressed paper can reduce the appearance of burrs during cutting.
[0028] As Figures 1-4As shown in the figure, a rotating block 4 is fixedly connected to the outer wall of the top of the return spring 308. A limiting strip 401 is rotatably connected to the inner surface of the rotating block 4. Extension plates 402 are fixedly connected to both outer sides of the limiting strip 401. A clamping groove 403 is formed on the outer side of the top of the placing column 305. The extension plates 402 are clamped and connected to the outer wall of the clamping groove 403. The return spring 308 and the placing column 305 form a clamping structure through the cooperation of the extension plates 402 and the clamping groove 403.
[0029] The pressing plate 309 is driven by the return spring 308 to be at the uppermost position of the guiding groove 306. At the same time, the limiting strip 401 at the top clamps the extension plates 402 on the inner wall of the clamping groove 403, thereby limiting the pressing plate 309 in place.
[0030] Working principle: When the device is in use, the staff places the paper to be cut on one side of the feeding table 101 close to the cylinder 2. At the same time, the cylinder 2 pushes the push plate 201 to push the paper towards the cutting plate 3. While pushing, the surface of the push plate 201 in contact with the paper is made as flat as possible. When the paper stack passes through the front end of the feeding table 101, the driving motor 203 is started at this time, and the driving motor 203 drives the cam 204 to start rotating. When the cam 204 rotates, the top thereof will touch the outer alignment plate 207. The alignment plate 207 makes a reciprocating movement towards the inner side of the feeding table 101 under the push of the cam 204. The alignment plate 207 moves closer to the feeding table 101 along the sliding groove 205. When the alignment plate 207 reciprocally touches the paper stack on the top of the feeding table 101, the two sides of the paper stack are continuously leveled. When the cam 204 rotates in the reverse direction and leaves the surface of the alignment plate 207, at this time, the alignment plate 207 retracts to its original position under the drive of the telescopic spring 206, and then fits the two sides of the paper stack again when the cam 204 rotates next time. Through the continuous pushing of the alignment plate 207, the paper stack to be cut is automatically leveled, and the edges of the paper are automatically aligned, thereby reducing the probability of the appearance of rough edges and achieving the effect of removing burrs.
[0031] When the push plate 201 pushes the paper to above the cutting plate 3, the staff determines that the paper reaches the position to be cut. At this time, the reset spring 308 drives the pressing plate 309 to the uppermost position of the guiding groove 306. At the same time, the limiting strip 401 at the top engages the extension plate 402 on the inner wall of the card slot 403, thereby limiting the pressing plate 309 in place. At this time, the limiting strip 401 is toggled to make the extension plate 402 leave the inner wall of the card slot 403. The reset spring 308 drives the pressing plate 309 to move downward due to its own spring self-shrinking force. The pressing plate 309 begins to descend along the guiding groove 306 and stops descending when it touches the highest point of the paper stack. The pressing plate 309 is tightly limited at the high position of the paper stack through the reset spring 308, thereby completing the pressing work of the paper. At this time, the hydraulic rod 303 is started again to drive the cutting blade 304 to cut the paper stack. The pressing plate 309 enables the cutting blade 304 to closely fit on the outer wall during cutting, and vertically cuts the paper on the outer side of the pressing plate 309. The uniformly pressed paper can reduce the appearance of burrs during cutting.
