Description

Technical Field

[0001] This application belongs to the technical field of corrugated cardboard box production equipment, specifically a corrugated cardboard box bonding and processing equipment. Background Technology

[0002] In the production process of corrugated cardboard boxes, corrugated cardboard needs to be bonded together. During this process, adhesive is applied to the corrugated cardboard to bond it together. The surface of ordinary corrugated cardboard has a large number of capillary structures, allowing the adhesive applied to the surface to penetrate into the paper through these pores. This anchoring effect creates a strong physical bond, thereby improving the strength of the corrugated cardboard box.

[0003] For example, application CN210733419U discloses a corrugated carton gluing device, belonging to the technical field of corrugated carton production equipment. It includes a frame, a gluing machine body mounted on the frame, and a cleaning device mounted on the side of the frame near the material receiving end. The cleaning device includes mounting seats fixedly mounted on both sides of the frame, with a first cleaning roller rotatably mounted on the mounting seats. Multiple sets of first bristles are arranged on the peripheral wall of the first cleaning roller, and the first bristles contact the corrugated carton on the gluing machine body. A second cleaning roller is also rotatably mounted on the mounting seat on the side of the first cleaning roller away from the frame, with multiple sets of second bristles arranged on the peripheral wall of the second cleaning roller. An adsorption hood is also mounted on the frame, with an adsorption mechanism connected to it for adsorbing dirt from the first and second bristles. A drive mechanism is also mounted on the frame to drive the first and second cleaning rollers to rotate in the same direction. This invention has the effect of cleaning dirt adhering to corrugated paper.

[0004] However, during the implementation of this application, it was discovered that the equipment in the application lacked a structure that could flatten the slight warping of the corrugated cardboard material during cardboard transportation or storage, resulting in poor adhesion. Utility Model Content

[0005] The purpose of this application is to provide a corrugated cardboard box gluing and processing equipment to solve the problems mentioned above.

[0006] The technical solution adopted in this application is as follows: A corrugated cardboard box bonding processing equipment includes a base. A flattening chamber shell is welded to the left and right edges of the front end of the upper surface of the base. A telescopic mechanism is set at the center of the upper surface of the flattening chamber shell. A fixed rod is connected to the lower end of the telescopic mechanism. A side fixing block is welded to the end of the fixed rod. An upper pressure shaft is rotatably arranged inside the side fixing block. A lower roller is rotatably arranged through the upper surface of the base to the lower end of the upper pressure shaft. A rotating shaft is connected to the center of the right end of the lower roller. A motor is installed at the end of the rotating shaft. A motor compartment is welded to the outside of the motor on the right surface of the base. An anti-tangling sheet is installed on the upper surface of the base on the outer circumferential surface of the lower roller.

[0007] By adopting the above technical solution, a flattening structure is added to the front end of the corrugated cardboard spraying structure. This eliminates slight warping that occurs during cardboard transportation or storage, allowing the cardboard to enter the gluing operation position more smoothly. This reduces the problem of incomplete glue adhesion caused by uneven corrugated cardboard. Furthermore, moderate flattening of the corrugated cardboard allows for tighter bonding between the corrugated core paper and the linerboard, and more uniform glue penetration. Although excessive flattening should be avoided during processing to prevent it from affecting the cardboard's compressive strength, corrugated cardboard generally has elastic memory and may gradually recover its original deformation over time after flattening. At the same time, an anti-tangling plate is installed on the upper side of the lower roller at the corrugated cardboard input platform to prevent corrugated cardboard from accidentally entering the roller equipment, causing the equipment to stop and resulting in equipment damage. This extends the equipment's service life and improves processing efficiency.

[0008] In a preferred embodiment, a support column is welded to the four corners of the lower surface of the base, and a support plate is fixedly connected to the lower end of the support column.

[0009] By adopting the above technical solution and adding a support structure to the bottom of the equipment, the vibration generated during the operation of the equipment can be dispersed, avoiding the loosening of screws or displacement of parts due to long-term vibration, thus extending the service life of the equipment. It is recommended to use support feet with rubber pads, which can reduce vibration and will not damage the external environment.

[0010] In a preferred embodiment, a glue spraying tank shell is welded to the left and right edges of the rear end of the upper surface of the base, and a curved conveying block is fixedly connected to the front edge of the lower surface. A glue inlet is provided through the upper surface of the glue spraying tank shell near the right edge. A glue delivery pipe is connected to the lower surface of the glue delivery pipe. A glue spraying block is fixedly connected to the lower end of the glue delivery pipe. Upper fixing blocks are welded to the upper edges of the left and right ends of the glue spraying block. A spring is provided on the lower surface of the upper fixing block. A pull rod fixing shaft is fixedly connected to the left surface of the glue spraying block. A pull rod is connected to the front end of the pull rod fixing shaft. An anti-slip pad is provided on the outer circumferential surface of the end of the pull rod. A pull rod groove is provided on the right surface of the glue spraying tank shell relative to the position of the pull rod.

[0011] By adopting the above technical solution, an operator pressing and gluing structure is set on the right side of the corrugated carton gluing equipment. The advantage of manual operation is that manual pressing can flexibly deal with different flute types of cardboard. When encountering local unevenness, the operator can adjust the pressing pressure in time, which is more precise than pure mechanical pressing. It can also avoid the trouble of frequent equipment adjustments, resulting in higher production efficiency. At the same time, the operator can visually check the quality of the glue line during the gluing process. If glue breaks, glue can be replenished immediately, reducing the defect rate in subsequent quality inspection stages.

[0012] In a preferred embodiment, curved side blocks are installed on the upper left and right edges of the base.

[0013] By adopting the above technical solution, curved side blocks are set on the left and right sides of the upper surface of the equipment to prevent the cardboard input position from shifting. The curved design allows the cardboard to naturally center, reducing the number of manual adjustments.

[0014] In a preferred embodiment, a beveled block is provided at the rear end edge of the upper surface of the base.

[0015] By adopting the above technical solution, an inclined output plate is added to the rear end of the corrugated cardboard box gluing equipment. The purpose is to use the gravity of the corrugated paper to slide down naturally, which saves the power consumption of the traditional conveyor belt. The inclination can ensure that the cardboard box slides out smoothly without being bumped or deformed due to excessive speed, and prevent the edges of the cardboard box from being worn.

[0016] In a preferred embodiment, protruding shafts are welded to the center positions of the left and right sides of the upper pressure shaft, and curved rings are provided on the side circumferential surfaces of the protruding shafts.

[0017] By adopting the above technical solution, a curved ring is used on the side of the upper pressure shaft to connect with the protruding shaft. The curved ring can reduce rotational friction when the upper pressure shaft rotates, and can make the operation quieter and reduce workshop noise.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0019] 1. In this application, a flattening structure is added to the front end of the corrugated cardboard spraying structure. This can eliminate slight warping caused by the cardboard during transportation or storage, allowing the cardboard to enter the gluing operation position more smoothly. This reduces the problem of poor glue adhesion caused by unevenness of the corrugated cardboard. Furthermore, moderate flattening of the corrugated cardboard can make the corrugated core paper and face paper bond more tightly and the glue penetration more evenly. Although excessive flattening should be avoided during processing to avoid affecting the compressive strength of the cardboard, corrugated cardboard generally has elastic memory and may gradually recover its original deformation over time after flattening. At the same time, an anti-tangling piece is set on the upper side of the lower roller at the position of the corrugated cardboard input platform to prevent the corrugated cardboard from accidentally entering the roller equipment, causing the equipment to stop and be damaged. This extends the service life of the equipment and improves processing efficiency.

[0020] 2. In this application, an operator pressing and gluing structure is set on the right side of the corrugated carton gluing equipment. The advantage of manual operation is that manual pressing can flexibly deal with different corrugation types of cardboard. When encountering local unevenness, the operator can adjust the pressing pressure in time, which is more precise than pure mechanical pressing and can avoid the trouble of frequent equipment adjustments, resulting in higher production efficiency. At the same time, the operator can visually check the quality of the glue line during the gluing process and can immediately replenish the glue if a break is found, reducing the defect rate in subsequent quality inspection stages.

[0021] 3. In this application, an inclined output plate is added to the rear end of the corrugated cardboard box gluing equipment. The purpose is to use the gravity of the corrugated paper to slide down naturally, which saves the power consumption of the traditional conveyor belt. The inclination can ensure that the cardboard box slides out smoothly without being bumped or deformed due to excessive speed, and prevent the edges of the cardboard box from being worn.

A flattening chamber 3 is welded to the left and right edges of the upper surface of the base 1. A telescopic mechanism 4 is positioned at the center of the upper surface of the flattening chamber 3. A fixing rod 18 is connected to the lower end of the telescopic mechanism 4. A side fixing block 17 is welded to the end of the fixing rod 18. An upper pressure shaft 10 is rotatably mounted inside the side fixing block 17. A lower roller 12 is rotatably mounted below the upper pressure shaft 10, extending through the upper surface of the base 1. A rotating shaft 19 is connected to the center of the right end of the lower roller 12. A motor 20 is mounted at the end of the rotating shaft 19. A motor compartment 7 is welded to the outside of the motor 20 on the right surface of the base 1. An anti-tangling plate 11 is installed on the upper surface of the base 1 at the outer circumferential surface of the lower roller 12. The equipment is used for gluing corrugated cardboard boxes. The addition of a flattening structure at the front end of the cardboard glue spraying structure eliminates slight warping that occurs during cardboard transportation or storage, allowing the cardboard to enter the glue application position more smoothly. This reduces the problem of incomplete glue adhesion caused by unevenness of the corrugated cardboard. Furthermore, moderate flattening of the corrugated cardboard allows for a tighter bond between the corrugated core paper and the linerboard, resulting in more even glue penetration. Although excessive flattening should be avoided during processing to prevent it from affecting the cardboard's compressive strength, corrugated cardboard generally has elastic memory and may gradually recover its original deformation over time after flattening. Additionally, an anti-tangling plate is installed on the upper side of the lower rollers at the cardboard input platform to prevent corrugated cardboard from accidentally entering the roller equipment, causing the equipment to stop and resulting in damage.

The curved design allows the cardboard to be naturally centered, reducing the number of manual adjustments.

The side circumferential surface of the protruding shaft 28 is provided with a curved ring 27. The curved ring is used to connect the upper pressure shaft to the protruding shaft. The curved ring can reduce rotational friction when the upper pressure shaft rotates and make it quieter during operation, reducing workshop noise.

[0037] The implementation principle of the corrugated cardboard box bonding processing equipment embodiment of this application is as follows: In this application, a flattening structure is added to the front end of the corrugated cardboard glue spraying structure, which can eliminate the slight warping generated during cardboard transportation or storage, allowing the cardboard to enter the glue application position more smoothly, reducing the problem of incomplete glue adhesion caused by uneven corrugated cardboard, and moderately flattening the corrugated cardboard can make the corrugated core paper and face paper adhere more tightly and the glue penetrate more evenly.
