Description

Technical Field

[0001] The present invention relates to the technical field of corrugated paper cutting devices, and particularly relates to an integrated device for detecting and trimming the rough edges of corrugated paper. Background Art

[0002] Corrugated cardboard is a multi-layer adhesive body, which consists of at least one layer of corrugated core paper interlayer and one layer of cardboard. To produce cardboard of different sizes, raw paper with dimensions close to the requirements is glued together, and then cut and trimmed to obtain corrugated cardboard with precise dimensions.

[0003] When the existing corrugated cardboard is cut, a pair of knife rings arranged vertically are mostly used for cutting the corrugated cardboard. However, the knife rings are installed on the knife shaft. If they are worn, the gap between the two knife rings will be too large, resulting in incomplete cutting of the corrugated cardboard and thus rough edges. For this reason, we propose an integrated device for detecting and trimming the rough edges of corrugated paper to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems existing in the prior art, and to propose an integrated device for detecting and trimming the rough edges of corrugated paper.

[0005] To achieve the above purpose, the present invention adopts the following technical scheme:

[0006] An integrated device for detecting and trimming the rough edges of corrugated paper, including a middle plate and a blade assembly. The blade assembly is installed on both the front and rear sides of the middle plate. Brackets are installed on both the front and rear sides of the middle plate. The blade assembly includes a horizontal blade and an inclined blade. The horizontal blade and the inclined blade are arranged alternately front and back. The horizontal blade is assembled and connected to the bracket. The right end of the inclined blade is rotatably connected to the bracket. A driving assembly is installed at the left end of the inclined blade;

[0007] During use, the corrugated paper is horizontally placed on the top of the middle plate and is pushed from left to right manually or by equipment drive. The width of the middle plate can be set to standard lengths of different sizes. When the front and rear ends of the corrugated paper extend beyond the front and rear ends of the middle plate, it indicates that there are rough edges at the front and rear ends of the corrugated paper. The driving assembly drives the left end of the inclined blade to swing up and down, so that the inclined blade and the horizontal blade reciprocally cut, and the rough edges can be quickly cut off to achieve synchronous trimming of the front and rear ends.

[0008] Preferably, the staggered position of the horizontal blade and the inclined blade is arranged at an acute angle, and tooth groove edges are respectively opened at the bottom end of the horizontal blade and the top end of the inclined blade;

[0009] The horizontal blade and the inclined blade are arranged at an acute angle at the staggered position, which can increase the contact area with the corrugated paper and prevent the corrugated paper from being squeezed and slipping to the left when the inclined blade moves upward, ensuring the smoothness of the trimming of the rough edge. The tooth groove edge has wave peaks and wave valleys, and the rough surface is more likely to embed in the corrugated paper to prevent slipping, further improving the stability of the trimming.

[0010] Preferably, a pressure roller is arranged at the staggered position of the horizontal blade and the inclined blade on the bracket, and a secondary roller is rotatably installed directly below the pressure roller at the rear of the middle plate;

[0011] The pressure roller arranged at the staggered position of the horizontal blade and the inclined blade can compact at the position of trimming the rough edge, and cooperate with the rotation of the secondary roller to press, which can ensure the flatness and prevent warping of the corrugated paper during the transportation of the corrugated paper, ensuring the thorough trimming of the rough edge.

[0012] Preferably, a vertically arranged laser generator is installed on the left part of the bracket, and a laser receiver is installed below the laser generator;

[0013] The laser generator can emit a laser beam downward, and the laser receiver can receive the laser signal. The laser generator is installed at the front and rear ends of the middle plate. When the corrugated paper is longer than the middle plate, it can block the laser beam. At this time, the laser receiver cannot receive the signal, and then a start signal can be transmitted, and the driving component does not need to work continuously and can stop working when there is no rough edge, reducing energy consumption.

[0014] Preferably, pin joint components are respectively installed at the left and right ends of the horizontal blade and the inclined blade, and symmetrically arranged guide frames are installed on the front side of the bracket. The pin joint components located at the left and right ends of the horizontal blade are slidably assembled with the guide frames;

[0015] Pin joint components are respectively installed at the left and right ends of the horizontal blade and the inclined blade. The horizontal blade is installed between the guide frames through the pin joint components and can slide left and right in the guide frames. When the horizontal blade is locally worn, the position of the intersection with the inclined blade can be adjusted left and right to make full use of the edge opening at the top of the horizontal blade.

[0016] Preferably, the pin joint component includes a rotating shaft. A notch is opened at the end of the rotating shaft. A threaded blind hole is arranged at the end of the rotating shaft at the notch. A spline head is installed at the end of the rotating shaft. Spline holes are opened at the left and right ends of the horizontal blade and the inclined blade to cooperate with the spline head;

[0017] A bolt can be screwed into the threaded blind hole of the rotating shaft. Through the setting of the notch, the end of the rotating shaft can be squeezed and opened, so that the horizontal blade can be fixed with the guide frame after adjustment, ensuring stable use. At the same time, a bearing can be connected to the right end of the inclined blade for stable rotational insertion with the bracket. The spline hole can ensure stable meshing between the rotating shaft and the blade and prevent relative rotation.

[0018] Preferably, a through pin hole is provided in the middle of the rotating shaft. A guide groove is provided on the side of the opening of the pin hole away from the spline head. A pin rod is inserted and installed in the pin hole. The circumferential side wall of the pin rod is treated with frosting. A ball head is provided at the bottom end of the pin rod. A top plate is installed at the top end of the pin rod. A pressure ring is sleeved and installed outside the pin rod, and a pin hole is provided in the middle of the pressure ring;

[0019] A pin rod can be inserted into the pin hole. The horizontal blade and the inclined blade are squeezed and fixed to the position of the rotating shaft through the pressure ring. A ball head is provided at the bottom end of the pin rod. A guide groove is provided on the side of the opening of the pin hole away from the spline head. When installing, the pin rod can be inserted into the pin hole more smoothly, and as it is inserted, the pressure ring is gradually pressed against the side wall of the blade, realizing flexible installation and stable crimping. The circumferential side wall of the pin rod is treated with frosting. After insertion, it rubs against the inner wall of the pin hole and the inner wall of the pin hole, and is stably installed to prevent detachment.

[0020] Preferably, the driving assembly includes a frame. Sliding openings are provided on the left and right sides of the frame. A sliding frame is slidably installed in the middle of the sliding openings. The pin joint assembly at the left end of the inclined blade is inserted into the sliding frame;

[0021] The frame is fixedly connected to the bracket. The up and down sliding of the sliding frame is guided through the sliding openings. When the sliding frame slides up and down, it can drive the left end of the inclined blade to swing up and down, and the pin joint assembly at the left end of the inclined blade can slide left and right in the sliding frame to ensure the smooth swing of the inclined blade.

[0022] Preferably, end frames are installed on the left and right sides of the sliding frame. The two end frames are respectively in sliding contact with the left and right outer walls of the frame;

[0023] The end frames are larger than the size of the sliding openings, and the end frames are respectively in sliding contact with the left and right outer walls of the frame, ensuring the stable up and down sliding of the sliding frame and preventing the sliding frame from falling off due to different left and right heights.

[0024] Preferably, a first eccentric wheel is rotatably installed below the sliding frame through a bracket, a second eccentric wheel is rotatably installed above the sliding frame through a bracket, a roller is rotatably installed in front of the first eccentric wheel and the second eccentric wheel, and the circumferential side wall of the roller is in pressing contact with the upper and lower outer walls of the sliding frame;

[0025] Synchronous wheels are respectively installed at the rear parts of the first eccentric wheel and the second eccentric wheel, and a synchronous belt is installed between the two synchronous wheels. The first eccentric wheel can be driven to rotate by an external motor, and then the second eccentric wheel is driven to be synchronously connected through the synchronous wheels and the synchronous belt. With the eccentrically installed roller, when the eccentric wheel rotates, it drives the sliding frame to move up and down smoothly with low friction. The eccentric wheel can rotate at a high speed, and then drive the sliding frame to slide stably at a high speed, realizing the high-speed swing of the inclined blade and ensuring smooth trimming of the burrs.

[0026] Compared with the prior art, the advantages of the present invention are as follows:

[0027] 1. Through the setting of the blade assembly, one of the two blades is inclined and the other is horizontal, and the two blades are arranged at an acute angle. When the laser generator detects the existence of burrs, the driving device drives the left end of the inclined blade to swing around the pin joint assembly at the right part, and the inclined blade approaches and moves away from the horizontal blade reciprocally to cut and remove the burrs. The edge-opening position at the bottom end of the horizontal blade is horizontal with the edge position of the corrugated cardboard, and it can press against the burrs to achieve stable and thorough cutting.

[0028] 2. Through the setting of the pin joint assembly, there is a rotating shaft at both the left and right ends of the two blades. The rotating shaft is equipped with a spline head, which can stably combine the blades to prevent slipping. Moreover, the rotating shaft is extruded with the blade through a retaining ring, and is assembled with a pin rod to prevent detachment, ensuring stable installation. The pin rod can be pulled out, and the semi-circular retaining ring can be quickly disassembled. Subsequently, when the rotating shaft is pulled out from the bracket, the blade can be disassembled and replaced.

[0029] 3. Through the setting of the driving assembly, the lower end of the inclined blade is connected to the sliding frame through a rotating shaft. The sliding frame can slide up and down. When the rotating shaft is driven by the sliding frame to slide up and down, it can slide left and right in the sliding frame. Moreover, the up and down sliding of the sliding frame is driven by an eccentric wheel. A roller is installed between the eccentric wheel and the sliding frame, which can roll and abut, reducing the frictional resistance between each other, and can smoothly achieve high-speed reciprocating driving.
