Description

Technical Field

[0001] The invention relates to the technical field of corrugated paper processing, and in particular to a corrugated core paper fluting and edge trimming device. Background Art

[0002] Corrugated cardboard is a multi-layer adhesive body, which is composed of at least one layer of wavy core paper interlayer (commonly known as "corrugated sheet", "corrugated paper", "corrugated core paper", "corrugated paper core", "corrugated base paper") and a layer of cardboard (also known as "box board", "box board"). It has high mechanical strength and can withstand collisions and falls during transportation. The actual performance of corrugated cardboard depends on three factors: the characteristics of the cardboard and the structure of the carton itself.

[0003] Corrugated core paper is processed from base paper into a wavy core paper interlayer. The existing processing method is to use an extrusion roller to roll the base paper to form the corresponding corrugated paper. However, due to the inability to move accurately with the base paper during rolling, a certain error will occur, resulting in an offset, which will cause the edge of the corrugated board to be uneven. The formed corrugated paper is difficult to cut accurately under the condition of lack of support. At the same time, due to the extremely short shaping time during rolling, it is easy to rebound and deform in the later stage, resulting in low processing quality and low processing efficiency.

[0009] Preferably, a through guide groove is provided on the top wall of the machine base, a guide rib is fixedly connected to the bottom of the lower pressure plate, the guide rib is slidably connected to the inside of the side mounting plate, and the bottom of the guide rib is fixedly connected to a lower extension frame, the elastic component is a tension spring installed between the lower extension frame and the machine base, and the tension spring is located on the side of the lower extension frame away from the swing plate.

[0010] Preferably, the bottom of both sides of the upper pressure plate away from one end of the lower pressure plate are fixedly connected with docking blocks, and the outer positions of both sides of the lower pressure plate corresponding to the docking blocks are fixedly connected with docking slots, and when the upper pressure plate and the lower pressure plate are in contact, the docking blocks are engaged with the docking slots.

[0011] Preferably, a lifting and cutting knife is vertically slidably installed on the end wall of the machine base near one end of the swing plate, and a wedge-shaped plug plate is fixedly connected to one side of the lower extension frame near the lifting and cutting knife, and the end of the wedge-shaped plug plate is arranged as an inclined wall, and the wedge-shaped plug plate penetrates the end wall of the machine base and cooperates with the bottom end of the lifting and cutting knife to push the lifting and cutting knife to rise to cut the corrugated paper.

[0012] Preferably, two sets of paper receiving baffles are arranged outside the machine base near one end of the lifting cutting knife, and the corrugated paper falls into the paper receiving baffles for collection after being cut.

[0013] Preferably, a compression box is provided in the bottom cavity of the machine base, and outward-expanding edge material receiving buckets are provided on the tops of both sides of the compression box. The edge material receiving buckets are used to receive the edge materials cut by the trimming knife and introduce them into the compression box. A compression plate is fixedly connected to one side of the bottom of the lower extension frame, and the compression plate slides laterally in the compression box to compress the edge materials.

[0014] In the above technical solution, the technical effects and advantages provided by the present invention are:

[0015] 1. The present invention drives the swing plate to rotate clockwise, utilizes the connection between the pull rod and the lower pressing plate, and guides the lower pressing plate with the lifting guide mechanism, so as to drive the lower pressing plate to move horizontally to the left and right. At the same time, by utilizing the resistance sliding between the damping sliding sleeve and the guide rod, and the guiding of the horizontal plate by the inclined groove, the upper pressing plate rises when it moves toward the paper roll, and falls when it moves in the opposite direction, so as to ensure that the upper pressing plate moves downward and fits with the lower pressing plate for pressing when it moves to the left, and the upper pressing plate rises and separates from the traction of the lower pressing plate when it moves to the right, and the base paper is corrugated by the squeezing of the upper pressing plate and the lower pressing plate. When the upper pressing plate moves to the right, it rises and separates from the lower pressing plate, and the lower pressing plate is reset. At this time, the base paper is not pressed and is stationary relative to the machine base. Therefore, during the processing, the base paper can be automatically pulled, and the trimming knife will cut the excess edge material along the side walls of the lower pressing plate and the upper pressing plate, so as to realize the synchronous processing of corrugated paper corrugation forming and trimming. In addition, since the device adopts plate-shaped pressing and can press for a certain period of time, the forming effect of the cardboard is maintained, and it is not easy to rebound and deform in the later stage, which improves the processing efficiency of corrugated paper, enhances the practicality of the equipment, and greatly reduces the processing cost;

[0016] 2. The present invention arranges a lifting and cutting knife at the end of the machine base, so that the lifting and cutting knife slides vertically at the end through supporting components such as sliding rails. When the lower pressing plate and the upper pressing plate have not reached the end, the lifting and cutting knife is located at the bottom. When the lower pressing plate and the upper pressing plate pull the base paper to move, the previously formed corrugated paper will pass over the lifting and cutting knife, and when the lower pressing plate is about to reach the end, the wedge-shaped insert plate passes through the end and cooperates with the bottom end of the lifting and cutting knife to push the lifting and cutting knife up. Therefore, when the lower pressing plate moves to the left to the limit, the lifting and cutting knife cuts the formed corrugated paper along the end walls of the lower pressing plate and the upper pressing plate, and makes it fall between the two paper receiving baffles, and then it is taken away. The corrugated paper can be pre-cut and formed when necessary, so as to facilitate the direct synthesis and processing into corrugated paperboard of corresponding size in the later stage, and further improve the processing efficiency of the device.

[0017] 3. The edge material cut off by the trimming knife of the present invention will gradually fall downward. At this time, the extended edge material receiving bucket can be used to receive the waste material and make it fall into the compression box. Moreover, since the docking block will also engage with the docking slot when the upper pressing plate and the lower pressing plate are docked, the base paper located outside the side of the lower pressing plate and the upper pressing plate has been cut once. Therefore, when the trimming knife cuts to this range later, the edge material will automatically break and fall, and then gradually accumulate in the compression box. By using the lower pressing plate to drive the compression plate to move left, after the waste material accumulates to a certain extent, the waste material can be continuously compressed until the waste material is taken out after the compression reaches the limit, thereby facilitating the collection and treatment of the waste material, and further improving the functionality and practicality of the device.

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] The present invention provides Figure 1-6The corrugated core paper corrugating and trimming device shown in the figure comprises a machine base 1, a lower pressing plate 2 and an upper pressing plate 3 are installed on the top of the machine base 1, and both are provided with a wavy protrusion for corrugating, a paper roll 13 is installed at one end of the machine base 1, and the base paper of the paper roll 13 passes through the lower pressing plate 2 and the upper pressing plate 3 after passing around the top of the machine base 1, so that when the lower pressing plate 2 and the upper pressing plate 3 are squeezed against each other, the base paper can be corrugated and formed, the lower pressing plate 2 is slidably installed on the top of the machine base 1, and the lower pressing plate 2 is connected with an automatic reset elastic component, after the lower pressing plate 2 is separated from the squeezing and pushing of the upper pressing plate 3, it can automatically rebound and reset backward, and the top of the upper pressing plate 3 is provided with a lifting guide mechanism 4 for guiding it in transverse movement, that is, the lifting guide mechanism 4 rises when the upper pressing plate 3 moves toward the paper roll 13, and falls when it moves in the opposite direction, so as to ensure that the upper pressing plate 3 is in a state of being pressed and reset when moving to the left. The pressing plate 3 moves down and fits with the lower pressing plate 2 for pressing. When moving to the right, the upper pressing plate 3 rises and separates from the traction of the lower pressing plate 2. The other end of the machine base 1 is rotatably installed with two sets of swing plates 5 through the shaft seat 11. The end of the swing plate 5 is rotatably installed with a pull rod 51. The two pull rods 51 extend to the top of the end of the lower pressing plate 2 away from the swing plate 5 and are rotatably connected thereto to support the rotating shaft of the swing plate 5 and drive the swing plate 5 to rotate clockwise by the motor. The connection between the pull rod 51 and the lower pressing plate 2 and the guidance of the lower pressing plate 2 by the lifting guide mechanism 4 can drive the lower pressing plate 2 to move horizontally to the left and right, and the bottom of the two pull rods 51 are installed with a trimming knife 52 that slides along the side walls of the lower pressing plate 2 and the upper pressing plate 3. When the pull rod 51 swings and drives the upper pressing plate 3, the trimming knife 52 will cut along the side walls of the lower pressing plate 2 and the upper pressing plate 3;

[0030] Furthermore, in the above technical solution, side mounting plates 12 are fixedly mounted on both sides of one end of the base 1, and the paper roll 13 is rotatably mounted on the inner side of the side mounting plate 12, thereby supporting the paper roll 13 and the lifting guide mechanism 4;

[0031] Furthermore, in the above technical solution, the lifting guide mechanism 4 includes a horizontal plate 41, and the inner wall of each of the side mounting plates 12 is provided with mutually parallel inclined grooves 14, and the end of the inclined groove 14 away from the swing plate 5 is inclined upward, and both sides of the horizontal plate 41 are fixedly connected with external convex guide blocks 43, and the external convex guide blocks 43 are slidably installed in the inclined groove 14, and one end of the horizontal plate 41 is fixedly connected with a guide rod 42, and the top of the upper pressure plate 3 is fixedly connected with a damping sliding sleeve 31 that is slidably fitted with the guide rod 42. When the upper pressure plate 3 starts to move right, the guide rod 42 can also be pushed to move right by utilizing resistance, so that under the guidance of the inclined groove 14, the horizontal plate 41 and the upper pressure plate 3 can first rise a distance, and then the horizontal plate 41 is stationary, and the upper pressure plate 3 moves horizontally. On the contrary, when the upper pressure plate 3 starts to move from right to left, the resistance is used to pull the horizontal plate 41 to move left first, that is, the upper pressure plate 3 is moved down under the guidance of the inclined groove 14, and then both move horizontally to the left;

[0032] Further, in the above technical solution, a through guide groove 15 is provided on the top wall of the machine base 1, a guide rib plate 25 is fixedly connected to the bottom of the lower pressure plate 2, the guide rib plate 25 is slidably connected to the inside of the side mounting plate 12, and a lower extension frame 21 is fixedly connected to the bottom of the guide rib plate 25, the elastic component is a tension spring 22 installed between the lower extension frame 21 and the machine base 1, and the tension spring 22 is located on the side of the lower extension frame 21 away from the wobble plate 5, thereby ensuring the stable sliding and automatic rebound of the lower pressure plate 2;

[0033] Furthermore, in the above technical solution, the bottoms of both sides of the upper pressing plate 3 away from one end of the lower pressing plate 2 are fixedly connected with docking blocks 32, and the outer sides of both sides of the lower pressing plate 2 are fixedly connected with docking slots 26 at positions corresponding to the docking blocks 32. When the upper pressing plate 3 is attached to the lower pressing plate 2, the docking blocks 32 are engaged with the docking slots 26, so that after the upper pressing plate 3 moves downward, not only the pressure can be used to drive the lower pressing plate 2, but also the engagement of the docking blocks 32 with the docking slots 26 can be used to effectively drive the lower pressing plate 2 to move;

[0034] Working principle: The shaft seat 11 is set up to support the rotating shaft of the swing plate 5, and the swing plate 5 is driven to rotate clockwise by the motor. The connection between the pull rod 51 and the lower pressure plate 2 and the guidance of the lifting guide mechanism 4 to the lower pressure plate 2 can drive the lower pressure plate 2 to move left and right. At the same time, by sliding the resistance between the damping sleeve 31 and the guide rod 42, when the upper pressure plate 3 starts to move right, the resistance can also be used to push the guide rod 42 to move right, so that under the guidance of the inclined slot 14, the horizontal plate 41 and the upper pressure plate 3 can first rise a distance, and then the horizontal plate 41 is stationary. When the upper pressing plate 3 stops, the upper pressing plate 3 moves horizontally. On the contrary, when the upper pressing plate 3 starts to move from right to left, the resistance is used to pull the horizontal plate 41 to move left first, that is, the upper pressing plate 3 moves downward under the guidance of the inclined slot 14, and is pressed and fitted with the upper pressing plate 3 on the right side. At the same time, the docking block 32 is also docked and engaged with the docking slot 26. Then, after the horizontal plate 41 is completely at the bottom and cannot move, the upper pressing plate 3 and the lower pressing plate 2 are both moved horizontally to the left, so that the base paper is corrugated by the squeezing of the upper pressing plate 3 and the lower pressing plate 2. At the same time, the base paper is pulled and transported by the joint movement of the lower pressing plate 2 and the upper pressing plate 3 until the base paper is corrugated. Figure 3 After the state shown, the upper pressing plate 3 moves to the left to the limit, and then starts to move right in the next step, and simultaneously rises and separates from the lower pressing plate 2, and the lower pressing plate 2 is pulled back to the right by the tension spring 22. At this time, the base paper is not pressed and is stationary relative to the machine base. Therefore, the base paper can be automatically pulled during the processing. By installing a trimming knife 52 at the bottom of the pull rod 51, when the pull rod 51 swings and drives the upper pressing plate 3, the trimming knife 52 will cut along the side walls of the lower pressing plate 2 and the upper pressing plate 3, that is, When the pull rod 51 swings down and drives the upper pressing plate 3 to move left, the trimming knife 52 will cut the excess edge material extending from both sides of the lower pressing plate 2 and the upper pressing plate 3, thereby completing the trimming processing of the corrugated paper and realizing the synchronous processing of corrugated paper fluting and trimming. Moreover, since the device adopts plate-shaped pressing and can press for a certain period of time, the forming effect of the cardboard is maintained, and it is not easy to rebound and deform in the later stage, which improves the processing efficiency of the corrugated paper, enhances the practicability of the equipment, and greatly reduces the processing cost.

[0035] Example 2

[0036] Based on Example 1, the difference is that Figure 1-4 A corrugated core paper corrugation and trimming device is shown, wherein a lifting cutting knife 6 is vertically slidably installed on the end wall of the base 1 near one end of the swing plate 5, and the lifting cutting knife 6 can cut the corrugated paper when it rises, and a wedge-shaped plug plate 24 is fixedly connected to one side of the lower extension frame 21 near the lifting cutting knife 6, and the end of the wedge-shaped plug plate 24 is set as an inclined wall, so that when the wedge-shaped plug plate 24 passes through the end wall of the base 1 and cooperates with the bottom end of the lifting cutting knife 6, the lifting cutting knife 6 is pushed to rise to cut the corrugated paper;

[0037] Furthermore, in the above technical solution, two sets of paper receiving baffles 17 are arranged outside the base 1 near one end of the lifting cutting knife 6, and the corrugated paper falls into the paper receiving baffles 17 after being cut, and then the cut corrugated paper is collected and taken out;

[0038] Working principle: By arranging a lifting and cutting knife 6 at the end of the machine base 1, the lifting and cutting knife 6 slides vertically at the end through supporting components such as sliding rails. When the lower pressing plate 2 and the upper pressing plate 3 have not reached the end, the lifting and cutting knife 6 is located at the bottom. When the lower pressing plate 2 and the upper pressing plate 3 pull the base paper to move, the previously formed corrugated paper will pass over the lifting and cutting knife 6, and when the lower pressing plate 2 is about to reach the end, the wedge-shaped insert plate 24 passes through the end and cooperates with the bottom end of the lifting and cutting knife 6 to push the lifting and cutting knife 6 up. When the lower pressing plate 2 moves to the left to the limit, the lifting and cutting knife 6 cuts the formed corrugated paper along the end wall of the lower pressing plate 2 and the upper pressing plate 3, and makes it fall between the two paper receiving baffles 17, and then takes it away. When necessary, the corrugated paper can be pre-cut and formed, so as to facilitate the direct synthesis and processing into corrugated paperboard of corresponding size in the later stage, and further improve the processing efficiency of the device.

[0039] Example 3

[0040] Based on Example 1, the difference is that Figure 1-5 A corrugated core paper corrugation and trimming device is shown, the bottom cavity of the base 1 is provided with a compression box 16, and the tops of both sides of the compression box 16 are provided with outward-expanded edge material receiving buckets 18, and the edge materials cut by the edge trimming knife 52 can fall into the edge material receiving buckets 18 when falling downward, and then be introduced into the compression box 16, and a compression plate 23 is fixedly connected to one side of the bottom of the lower extension frame 21, and the compression plate 23 slides laterally in the compression box 16, and when the compression plate 23 moves to the left, the concentrated edge materials can be compressed;

[0041] Working principle: By setting a compression box 16 at the bottom of the machine base 1 and extending a compression plate 23 at the bottom of the lower pressing plate 2, the edge material cut off by the trimming knife 52 will gradually fall downward while the device is running. At this time, the extended edge material receiving bucket 18 can be used to receive the waste material and make it fall into the compression box 16. Moreover, since the docking block 32 will also engage with the docking slot 26 when the upper pressing plate 3 is docked with the lower pressing plate 2, at this time, the range of the base paper located outside the sides of the lower pressing plate 2 and the upper pressing plate 3 has been compressed once. Therefore, when the trimming knife 52 cuts to this range later, the edge material will automatically break and fall, and then gradually accumulate in the compression box 16. By using the lower pressing plate 2 to drive the compression plate 23 to move left, after the waste material accumulates to a certain extent, the waste material can be continuously compressed until the waste material is taken out after the compression reaches the limit, thereby facilitating the collection and treatment of the waste material, further improving the functionality and practicality of the device.

[0042] In summary, by rotating the swing plate 5, the upper pressing plate 3 is driven to move left and right by the connection between the pull rod 51 and the upper pressing plate 3, and the inclined groove 14 is used to guide the horizontal plate 41, so that the upper pressing plate 3 is pressed down when it moves left and raised when it moves right, thereby not only realizing the corrugation forming function of the base paper, but also improving the forming and shaping effect of the corrugated paper due to the pressing time, and at the same time, the movement and pressing of the upper pressing plate 3 are used to realize the continuous traction function of the base paper, and when the upper pressing plate 3 is pulled by the pull rod 51, the movement of the trimming knife 52 also realizes the function of cutting the excess edge material after forming. At the same time, by utilizing the cooperation between the wedge-shaped insert plate 24 and the lifting and cutting knife 6, and then cooperating with the movement of the lower pressure plate 2, the lifting and cutting knife 6 can be driven to lift and lower, and the automatic cutting function of the formed corrugated paper can also be realized. Since the edge material is received by the edge material receiving bucket 18 and then falls into the compression box 16, the movement of the lower pressure plate 2 drives the compression plate 23 to squeeze the waste material, and the compression function of the waste material is also realized, thereby greatly improving the forming processing effect of the device, greatly improving the processing efficiency, reducing the mutual transportation of materials, and since the device can only drive the swing plate 5 for energy, it also reduces energy consumption.

[0043] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
