Description

Technical Field

[0001] The invention relates to the technical field of corrugated paper processing, in particular to a corrugated paper surface treatment device and process. Background Art

[0002] Corrugated paper is a plate-like material formed by gluing noodle paper and corrugated paper formed by corrugating rollers. Corrugated paper is a lightweight, low-cost packaging material with good mechanical properties, and is widely used in the packaging of various products. However, corrugated paper itself is not waterproof. Once it encounters water, it will absorb moisture and become soft, affecting its physical properties and packaging effect. Therefore, in order to meet the packaging needs of different products, especially those that need to be moisture-proof and waterproof, such as food, medicine, electronic products, etc., it is necessary for staff to apply glue on the surface of the corrugated paper to stick the waterproof film to the surface of the corrugated paper, so as to achieve the function of treating the surface of the corrugated paper. However, the existing device has the following defects when gluing the corrugated paper and the waterproof film:

[0003] At present, glue is sprayed on the surface of corrugated paper through a nozzle and then glued. However, spraying glue through the nozzle once will cause the glue to penetrate into the inside of the corrugated paper, resulting in less glue on the surface of the corrugated paper, affecting its viscosity. In addition, when the corrugated paper and the waterproof film are glued together, they need to be pressed by a roller, so that the space at the gap connection between the corrugated paper and the waterproof film is smaller. The structure of the glue spraying is not convenient to extend into the gap connection and spray glue to the connection again, resulting in insufficient glue required between the waterproof film and the corrugated paper. Summary of the invention

[0004] The purpose of the present invention is to provide a corrugated paper surface treatment device and process to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides a corrugated paper surface treatment device, comprising a protective shell and a collection box, wherein a glue coating structure is arranged inside the protective shell, an adjustment structure for controlling the flow rate of glue is arranged inside the protective shell, a cleaning structure for cleaning the surface of a waterproof membrane is arranged inside the protective shell, and a collection structure is arranged inside the protective shell;

[0006] When the corrugated paper is coated with glue, the coating structure drives the adjustment structure to adjust the spray angle to adapt to the glue spraying at the connection between the corrugated paper and the waterproof membrane;

[0007] The cleaning structure is squeezed and moved upward by rotating the rubber coating structure to press against the inner surface of the waterproof membrane. At the same time, the collecting structure is squeezed and moved upward to reduce the size of the cavity formed between the cleaning structure and the collecting structure for collecting impurities. Under the action of gravity of impurities in the cavity, the outer wall of the rubber coating structure is squeezed to increase the water pressure.

[0008] As a further improvement of the technical solution, the collection box and the protective shell are detachably connected, and a cylinder is installed inside the protective shell.

[0009] As a further improvement of the present technical solution, the rubber coating structure includes a sliding plate fixedly connected to the output shaft end of the cylinder, the sliding plate is slidingly connected to the protective shell, two racks are fixedly connected to one side of the sliding plate, and a gear is provided on the side of the rack away from the sliding plate.

[0010] As a further improvement of the present technical solution, a rotating rod is fixedly connected to one side of the gear, a fixed plate is provided on the side of the rotating rod away from the gear, the fixed plate is fixedly connected to the protective shell, a guide groove is provided on the side of the fixed plate close to the gear, and a convex column is slidably connected inside the guide groove.

[0011] As a further improvement of the present technical solution, the adjustment structure includes a sliding rod that is slidably connected to the rotating rod, the sliding rod is slidably connected to the convex column inside the guide groove of the fixed plate and is magnetically connected, one side of the sliding rod is fixedly connected to a movable frame, one side of the movable frame is rotatably connected to two swinging plates, a connecting shaft is fixedly connected to the middle part of the two swinging plates, the connecting shaft is rotatably connected to the rotating rod, and a circular hole is opened on the surface of the movable frame.

[0012] As a further improvement of the present technical solution, the cleaning structure includes two groups of fixed blocks fixedly connected to the surface of the rotating rod, the two groups of fixed blocks are symmetrically arranged along the center line of the rotating rod, and two cleaning plates are slidably connected inside the collecting box. The side of the two cleaning plates away from the fixed blocks is arc-shaped, and the side of the cleaning plate close to the rotating rod is fit-connected to the fixed blocks.

[0013] As a further improvement of the present technical solution, the collection structure includes a silicone sleeve that penetrates the rotating rod, a sliding block is provided on the side of the silicone sleeve close to the collection box, the sliding block is slidably connected to the collection box, and a collection plate is fixedly connected to the side of the sliding block away from the silicone sleeve, and the collection plate is inclined inside the collection box.

[0014] As a further improvement of the technical solution, a corrugated paper surface treatment device and a corrugated paper surface treatment process are proposed:

[0015] S1. When corrugated paper is produced, the gluing structure drives the adjusting structure to rotate, thereby adjusting the speed and distance of gluing the corrugated paper;

[0016] S2. During the process of gluing corrugated paper, the cleaning structure can be driven by the change of the position of the gluing structure to collect impurities on the surface of the waterproof membrane;

[0017] S3. After the impurities are collected, the water pressure inside the rotating rod can be adjusted by squeezing the rubber coating structure through the collecting structure.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the corrugated paper surface treatment equipment and process, through the cooperation between the sliding plate, rack, gear and mobile frame and other structures, glue can be evenly sprayed on different positions of the corrugated paper and the waterproof film. The uniform distribution of glue can ensure that each layer of the corrugated waterproof film can be firmly bonded together, thereby improving the overall quality of corrugated paper production.

[0020] 2. In this corrugated paper surface treatment equipment and process, the cooperation between the movable frame, the sliding rod, the swing plate and the connecting shaft and other structures can change the water pressure in the rotating rod while spraying glue at different positions, so that different liquid amounts of glue can be sprayed at different positions. Corrugated paper at different positions requires different amounts of glue to ensure the best bonding effect. By adjusting the water pressure, it can be ensured that each position obtains the right amount of glue, thereby improving the overall bonding quality of the corrugated paper and the strength of the corrugated paper.

[0021] 3. In this corrugated paper surface treatment equipment and process, impurities on the surface of the waterproof membrane can be collected and cleaned alternately through the cooperation between fixed blocks, rotating rods, gears and other structures. The presence of impurities will affect the strength, flatness and appearance of the corrugated paper. Cleaning impurities can ensure the surface quality of the corrugated paper, making it smoother and more uniform, thereby improving the overall quality of the corrugated paper.

[0022] 4. In this corrugated paper surface treatment equipment and process, the pressure inside the rotating rod can be increased by the cooperation between the silicone sleeve, the sliding block, the collecting plate and other structures, so that the rotating rod can have sufficient water pressure, so that glue can be sprayed more fully onto the surface of the corrugated paper.

[0035] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example 1

[0037] Corrugated paper is a plate-like material formed by gluing noodle paper and corrugated paper formed by corrugating rollers, and is generally divided into two categories: single corrugated paperboard and double corrugated paperboard. This embodiment provides a corrugated paper surface treatment device, including a protective shell 1 and a collection box 11. The protective shell 1 is provided with a glue coating structure 2, the protective shell 1 is provided with a regulating structure 3 for controlling the flow rate of glue, the protective shell 1 is provided with a cleaning structure 4 for cleaning the surface of the waterproof membrane, and the protective shell 1 is provided with a collection structure 5;

[0038] When the corrugated paper is coated with glue, the coating structure 2 drives the adjustment structure 3 to adjust the spraying angle to adapt to the glue spraying at the connection between the corrugated paper and the waterproof membrane;

[0039] The cleaning structure 4 is pressed upward by the rotation of the rubber coating structure 2 to press against the inner surface of the waterproof membrane, and the collecting structure 5 is pressed upward to reduce the size of the cavity formed between the cleaning structure 4 and the collecting structure 5 for collecting impurities. Under the action of the gravity of the impurities in the cavity, the outer wall of the rubber coating structure 2 is pressed to increase the water pressure;

[0040] When the corrugated paper is coated with glue, the coating structure 2 drives the adjustment structure 3 to adjust the spray angle to adapt to the glue spraying at the connection between the corrugated paper and the waterproof membrane. At the same time, the coating structure 2 can drive the cleaning structure 4 to clean the surface of the waterproof membrane.

[0041] When the glue-coated structure 2 rotates, it will fit with the cleaning structure 4, and then the cleaning structure 4 will fit with the waterproof membrane to be used. The cavity formed between the collecting structure 5 and the cleaning structure 4 can collect impurities, and the glue-coated structure 2 fits with the cleaning structure 4 and also fits with the collecting structure 5. At this time, the gravity of the impurity shape inside the collecting structure 5 squeezes the outer wall of the glue-coated structure 2. At this time, the water pressure in the glue-coated structure 2 will increase, and then the distance when spraying glue at the connection between the corrugated paper and the waterproof membrane can be increased.

[0042] The present invention takes into account that currently glue is sprayed on the surface of the corrugated paper through a nozzle and then glued. However, spraying glue through the nozzle once will cause the glue to penetrate into the inside of the corrugated paper, resulting in less glue on the surface of the corrugated paper, affecting its viscosity. If more glue is sprayed at one time, when the waterproof film is laid on the surface of the corrugated paper for pasting, the excess glue is easily squeezed out. Therefore, the glue coating structure 2 can reciprocate inside the protective shell 1 to drive the adjustment structure 3 to rotate synchronously. When the adjustment structure 3 rotates to a certain angle, a small amount of glue can be sprayed on the surface of the corrugated paper to which the waterproof film is being pasted, so that the glue can form a glue layer on its surface. The glue forms a thin film on the surface of the corrugated paper, which helps the waterproof film to better fit the corrugated paper, reduce the penetration of air and moisture, improve the overall sealing, and avoid damage to the corrugated paper caused by a large amount of glue;

[0043] In addition, when the corrugated paper and the waterproof film are glued together, they need to be pressed by a roller, so that the space at the gap connection between the corrugated paper and the waterproof film is smaller. The glue spraying structure is not convenient to extend into the gap connection and spray glue to the connection again, resulting in insufficient glue between the waterproof film and the corrugated paper. When the adjustment structure 3 is rotated to an angle opposite to the above, the adjustment structure 3 can control the water pressure in the glue coating structure 2, so that the glue can be sprayed on the junction of the corrugated paper and the waterproof film, so that they can be glued more tightly.

[0044] In order to facilitate the discharge of impurities in the collection box 11 after the corrugated paper and the waterproof film are bonded, the collection box 11 and the protective shell 1 are detachably connected by bolts and nuts, and a cylinder 12 is installed inside the protective shell 1 to discharge impurities in the collection box 11 so that it can be reused many times.

[0045] On the basis of the above, the specific structure needs to be disclosed in detail:

[0046] To enable the gear 22 to rotate back and forth, the rubber-coated structure 2 includes a sliding plate 21 fixedly connected to the output shaft end of the cylinder 12. The sliding plate 21 is slidingly connected to the protective shell 1. Two racks 2101 are fixedly connected to one side of the sliding plate 21. A gear 22 is provided on the side of the rack 2101 away from the sliding plate 21.

[0047] Specifically, refer to Figure 2 When corrugated paper is produced, the staff starts the cylinder 12, so that the sliding plate 21 fixedly connected to the cylinder 12 slides back and forth inside the protective shell 1. When the sliding plate 21 moves, it can drive the two racks 2101 to intermittently engage with the gear 22. When the two racks 2101 engage with the gear 22, the gear 22 can reciprocate inside the protective shell 1. When the gear 22 reciprocates, it is convenient to spray the glue at different angles later.

[0048] When the two racks 2101 are not meshed with the gear 22, the rotating rod 24 is in a stationary state. At this time, sufficient glue can be sprayed on the surface of the corrugated paper below the rotating rod 24 to make it more firmly adhered.

[0049] In order to enable the rotating rod 24 to rotate at multiple angles, a rotating rod 24 is fixedly connected to one side of the gear 22, a fixing plate 23 is provided on the side of the rotating rod 24 away from the gear 22, the fixing plate 23 is fixedly connected to the protective shell 1, a guide groove is provided on the side of the fixing plate 23 close to the gear 22, and a convex column is slidably connected inside the guide groove.

[0050] refer to Figure 2 , Figure 3 When the gear 22 rotates, the rotating rod 24 can be driven to rotate synchronously, and the interior of the rotating rod 24 is connected to the water outlet end of the water pump installed outside the device. When the rotating rod 24 rotates, the glue inside it can be sprayed on the surface of the corrugated paper. The setting of the water pump can provide sufficient glue to the interior of the rotating rod 24.

[0051] In order to spray the sufficient glue inside the rotating rod 24 at an angle, the adjustment structure 3 includes a sliding rod 31 that is slidably connected to the rotating rod 24, and the sliding rod 31 is magnetically connected to the convex column that is slidably connected to the guide groove of the fixed plate 23. One side of the sliding rod 31 is fixedly connected to a moving frame 32, and one side of the moving frame 32 is rotatably connected to two swinging plates 33. The middle part of the two swinging plates 33 is fixedly connected to a connecting shaft 34, and the connecting shaft 34 is rotatably connected to the rotating rod 24. A circular hole is opened on the surface of the moving frame 32.

[0052] Specifically, refer to Figure 5 and Figure 6A circular hole is opened on the surface of the movable frame 32 so that the glue inside the rotating rod 24 can be sprayed onto the surface of the corrugated paper through the circular hole. At the same time, the two swing plates 33 can guide the glue sprayed inside the circular hole while the rotating rod 24 rotates, so as to avoid the occurrence of excessive glue spraying range.

[0053] Specifically, when the rotating rod 24 rotates to spray glue, it can drive the sliding rod 31 to rotate back and forth. When the sliding rod 31 rotates, it can drive the magnetically connected protrusion on one side to rotate in the guide groove provided on the surface of the fixed plate 23. When the sliding rod 31 reciprocates by a certain angle, the sliding rod 31 slides toward the side close to the connecting shaft 34 through the cooperation between the guide groove and the protrusion, and at this time, the rotating rod 24 will swing through the cooperation between the sliding plate 21 and the rack 2101.

[0054] The rotating rod 24 swings toward the side close to the cylinder 12 to spray glue on the connection between the corrugated paper and the waterproof membrane. At this time, by spraying glue again, sufficient glue can be provided when the corrugated paper and the waterproof membrane are adhered. At the same time, a small amount of glue can penetrate into the surface of the waterproof membrane. Since the sliding rod 31 moves toward the side close to the swing plate 33 at this time, the sliding rod 31 can drive the moving frame 32 to move synchronously. When the moving frame 32 moves, it can drive the swing plate 33 connected to it to swing relative to each other around the connecting shaft 34. At this time, the two swing plates 33 are above the connecting shaft 34 and will move closer to each other. When the sliding rod 31 is swung in the direction, the two swing plates 33 located below the sliding rod 31 will swing away from the sliding rod 31. When the two swing plates 33 are swung upward, the circular holes on the surface of the movable frame 32 can be blocked, thereby reducing the number of circular holes, which will cause the water pressure inside the rotating rod 24 to increase. When the water pressure increases, the glue inside the rotating rod 24 can be sprayed farther. At the same time, when the two swing plates 33 are swung upward, the glue sprayed through the circular holes can be accurately sprayed to the connection between the corrugated paper and the waterproof membrane, thereby avoiding waste caused by excessive spraying of glue.

[0055] Specifically, at this time, the rotating rod 24 swings toward the side away from the cylinder 12 to spray glue on the pressed corrugated paper, and the surface of the corrugated paper can be pre-treated by spraying glue thereon. From the above description, it can be known that when the rotating rod 24 swings toward the side away from the cylinder 12, the glue sprayed by the movable frame 32 and the swing plate 33 can also be sprayed on the pressed corrugated paper more accurately, so that the glue can have sufficient time to contact the surface of the corrugated paper, so that the inside of the corrugated paper can absorb enough glue. When the rotating rod 24 is in a stationary state, the glue is sprayed on the surface of the corrugated paper, and the glue can accumulate on the surface of the corrugated paper, thereby facilitating the processing efficiency of the corrugated paper.

[0056] When the rotating rod 24 does not swing, the glue is sprayed vertically on the surface of the corrugated paper through the circular holes on the surface of the movable frame 32. Figure 5 The swing plate 33 and the moving frame 32 are in a state where they have not yet rotated, and the rotating rod 24 sprays sufficient glue on the surface of the corrugated paper through the circular holes opened on the surface of the moving frame 32, so that the corrugated paper can have sufficient glue when pressed.

[0057] In order to clean and collect impurities on the sticky surface of the waterproof film and the corrugated paper, the cleaning structure 4 includes two groups of fixed blocks 41 fixedly connected to the surface of the rotating rod 24. The two groups of fixed blocks 41 are symmetrically arranged along the center line of the rotating rod 24. Two cleaning plates 42 are slidably connected to the inside of the collection box 11. The side of the two cleaning plates 42 away from the fixed block 41 is arc-shaped, and the side of the cleaning plate 42 close to the rotating rod 24 is in a close connection with the fixed block 41.

[0058] refer to Figure 7 and Figure 8 In the initial state, the fixed block 41 close to the cylinder 12 is in contact with the cleaning plate 42 close to one side of the cylinder 12, and the side of the cleaning plate 42 away from the fixed block 41 is in contact with the bottom of the waterproof membrane. At this time, the waterproof membrane is moved by external equipment, and then one side of the waterproof membrane can be cleaned by the fixed block 41 to avoid the problem of loose adhesion between the waterproof membrane and the corrugated paper.

[0059] When the rotating rod 24 drives the fixed block 41 to rotate toward the side close to the cylinder 12, the fixed block 41 close to the cylinder 12 will not fit with the cleaning plate 42 on the same side, and the cleaning plate 42 will slide toward the side close to the rotating rod 24 by its own gravity.

[0060] At this time, the fixed block 41 on the side away from the cylinder 12 will fit with the cleaning plate 42 on the side away from the cylinder 12, so that the surface of the waterproof membrane can continue to be cleaned alternately by the cleaning plate 42 on the side away from the cylinder 12, avoiding the situation where the surface of the cleaning plate 42 heats up due to long-term friction between the cleaning plate 42 and the waterproof membrane.

[0061] Since the two cleaning plates 42 have an arc-shaped side away from the fixing block 41 , the impurities on the surface of the waterproof membrane are collected by the cleaning plates 42 and then fall into the collecting box 11 .

[0062] In order to increase the water pressure inside the rotating rod 24 again, the collecting structure 5 includes a silicone sleeve 51 that passes through the rotating rod 24. A sliding block 52 is provided on the side of the silicone sleeve 51 close to the collecting box 11. The sliding block 52 is slidably connected to the collecting box 11. The side of the sliding block 52 away from the silicone sleeve 51 is fixedly connected to a collecting plate 53. The collecting plate 53 is inclined inside the collecting box 11.

[0063] Specifically, refer to Figure 8, because the collecting plate 53 is disposed inside the collecting box 11 , the impurities collected by the two cleaning plates 42 will be collected on the surface of the collecting plate 53 ;

[0064] When impurities are collected inside the collecting plate 53, the impurities will be spread on its surface. At this time, the silicone sleeve 51 is in an expanded state due to the water pressure in the rotating rod 24. When the silicone sleeve 51 contacts the sliding block 52, the sliding block 52 will squeeze the silicone sleeve 51 synchronously with the impurities distributed on the surface of the collecting plate 53 through the collecting plate 53, so that the pressure in the rotating rod 24 that passes through the inside of the silicone sleeve 51 increases again. At the same time, after the rotating rod 24 rotates a certain angle, the rotating rod 24 is affected by the moving frame 32 and the swing plate 33. The water pressure inside the rotating rod 24 will continue to increase. At this time, the increase in water pressure on the rotating rod 24 will cause the silicone sleeve 51 to expand. At the same time, the silicone sleeve 51 will fit with the sliding block 52 when it rotates. At this time, the silicone sleeve 51 can drive the collecting plate 53 to slide in the direction away from the rotating rod 24 through the sliding block 52, so that the movement of the collecting plate 53 can collect the impurities inside it to the two sides of the collecting box 11 according to its own gravity, thereby avoiding the staff from cleaning the inside of the collecting box 11 again.

[0065] At the same time, when the water pressure in the rotating rod 24 slowly decreases, the silicone sleeve 51 will gradually decrease with the water pressure, and then the sliding block 52 will drive the collecting plate 53 to slide toward the rotating rod 24. At this time, the distance between the collecting plate 53 and the collecting box 11 will become larger, thereby preventing too many impurities from being collected into the collecting box 11.
