Description

Technical Field

[0001] This utility model relates to the field of paper pressing structure technology, and in particular to a telescopic paper pressing structure for a fully automatic double-plate gluing machine. Background Technology

[0002] In the corrugated box manufacturing industry, fully automatic double-sheet gluing machines are key equipment for achieving rapid corrugated box forming. They complete the gluing and forming of the corrugated box through precise feeding, gluing, and pressing of two pieces of cardboard. The paper pressing structure, as an important component of the gluing machine, directly affects the stability of the cardboard feeding, the paper feeding accuracy, and the final gluing quality.

[0003] Traditional paper pressing structures typically have rigid pressure settings, which cannot be adaptively adjusted according to changes in cardboard thickness. When cardboard thickness fluctuates, excessive pressure can easily cause cardboard deformation, or insufficient pressure can cause cardboard conveying deviation, affecting subsequent bonding accuracy. To solve the above problems, this application proposes a telescopic paper pressing structure for a fully automatic double-plate gluing machine. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a telescopic paper pressing structure for a fully automatic double-plate gluing machine. Through the combination of elastic components and rotating paper pressing components, it can automatically buffer the impact caused by changes in paper thickness, ensuring a stable paper pressing effect even when the paper thickness fluctuates. With the help of a sliding fit structure, the entire paper pressing mechanism can be driven to move smoothly along a set direction and the paper pressing position can be quickly adjusted.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The fully automatic double-plate gluing machine features a telescopic paper-pressing structure, including a wall panel. A straight arm is fixedly connected to the side wall of the wall panel. Multiple U-shaped seats are mounted on the straight arm, each U-shaped seat has a disassembly and assembly mechanism, and two elastic plates are fixedly connected to the bottom of each U-shaped seat. A paper-pressing wheel is rotatably connected to the bottom of each elastic plate. An end paper-pressing plate is fixedly connected to the end of the straight arm away from the wall panel. A fixed plate is fixedly connected to the top of the wall panel, and two sliding blocks are fixedly connected to the fixed plate. Each sliding block has a slide rail slidably connected to it. A hydraulic rod is fixedly connected to the side wall of the fixed plate, and a locking block is fixedly connected to the output end of the hydraulic rod.

[0007] Preferably, the disassembly and assembly mechanism includes two sets of through holes penetrating the front and back of the U-shaped seat, each through hole being threaded with a fastening bolt, and the front and back of the straight arm having two mounting grooves, the ends of the two fastening bolts being inserted into the corresponding mounting grooves and abutting against their inner walls.

[0008] Preferably, the outer wall of the fastening bolt is provided with external threads, and the inner wall of the through hole is provided with internal threads that mate with the external threads.

[0009] Preferably, the bottom height of the pressure roller is lower than the bottom height of the end pressure sheet.

[0010] Preferably, the outer wall of the slide rail is provided with two limiting strips, and the inner wall of the sliding block is provided with a limiting groove that cooperates with the two limiting strips.

[0011] Preferably, the top of the card block is provided with anti-slip texture.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. By combining the elastic component with the rotating paper pressing component, the effect of changes in paper thickness can be automatically buffered, ensuring a stable paper pressing effect even when the paper thickness fluctuates, and avoiding paper deformation due to improper pressure.

[0014] 2. The sliding fit structure can drive the entire paper pressing mechanism to move smoothly in the set direction, quickly adjust the paper pressing position, and maintain the synchronization of each paper pressing component during the adjustment process, ensuring the consistency of the paper feeding path and improving operating efficiency.

[0015] 3. The disassembly and assembly mechanism allows for quick disassembly and installation of the paper pressing assembly and the main structure. When a single component is worn or malfunctions, there is no need to disassemble the entire assembly, which reduces maintenance difficulty and downtime, and lowers maintenance costs.

[0016] In summary, the combination of the elastic component and the rotating paper pressing component can automatically buffer the impact of changes in paper thickness, ensuring a stable paper pressing effect even when the paper thickness fluctuates; the sliding fit structure can drive the entire paper pressing mechanism to move smoothly along the set direction and quickly adjust the paper pressing position.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-2 The fully automatic double-plate gluing machine with telescopic paper pressing structure includes a wall panel 1, which serves as the installation base for the entire structure, providing stable support for the straight arm 2 and the fixed plate 10. The straight arm 2 is fixedly connected to the side wall of the wall panel 1. The straight arm 2 is used to support the U-shaped seat 3 and the end paper pressing plate 9, forming the main frame of the paper pressing mechanism. Multiple U-shaped seats 3 are installed on the straight arm 2. The U-shaped seats 3 are used to fix the elastic plate 7, so that the paper pressing wheel 8 can be stably installed and play its paper pressing role. Each U-shaped seat 3 is equipped with a disassembly and assembly mechanism, which realizes the detachable connection between the U-shaped seat 3 and the straight arm 2, which facilitates later maintenance and replacement.

[0022] The disassembly and assembly mechanism includes two sets of through holes 5 penetrating the front and back of the U-shaped seat 3. The through holes 5 provide installation channels for the fastening bolts 4, allowing them to pass through the U-shaped seat 3 and connect to the straight arm 2. Each through hole 5 is threaded with a fastening bolt 4, which fixes the U-shaped seat 3 to the straight arm 2 through the threaded engagement, ensuring connection stability. The outer wall of the fastening bolt 4 has external threads, and the inner wall of the through hole 5 has internal threads that mate with the external threads. The engagement of the internal and external threads allows the fastening bolt 4 to be tightened or loosened, realizing the installation and disassembly of the U-shaped seat 3. Two mounting grooves 6 are opened on both the front and back of the straight arm 2. The mounting grooves 6 provide space for the ends of the fastening bolts 4, enhancing the fixing effect. The ends of the two fastening bolts 4 are respectively inserted into the corresponding mounting grooves 6 and abut against their inner walls.

[0023] Two elastic plates 7 are fixedly connected to the bottom of each U-shaped seat 3. The elastic plates 7 have elastic deformation capability and can automatically adjust the pressure of the paper pressing roller 8 according to the change of paper thickness. The bottom of each elastic plate 7 is rotatably connected to the paper pressing roller 8. The paper pressing roller 8 enables the paper to be fed smoothly by rotation and reduces paper feeding resistance. The end of the straight arm 2 away from the wall plate 1 is fixedly connected to the end pressing plate 9. The end pressing plate 9 assists in pressing the end of the paper to ensure the integrity of the paper feeding. The bottom height of the paper pressing roller 8 is lower than the bottom height of the end pressing plate 9. This height setting allows the paper pressing roller 8 to contact the paper first, forming a stepped paper pressing effect with the end pressing plate 9.

[0024] A fixed plate 10 is fixedly connected to the top of the wall panel 1. The fixed plate 10 connects the wall panel 1 and the sliding block 11 to realize the position adjustment function of the overall structure. Two sliding blocks 11 are fixedly connected to the fixed plate 10. The sliding blocks 11 cooperate with the slide rail 12 to guide the entire paper pressing structure to move along the slide rail 12. Each sliding block 11 is provided with a slide rail 12 that is slidably connected to it. The slide rail 12 provides a moving track for the sliding block 11 and limits the adjustment direction of the paper pressing structure. The outer wall of the slide rail 12 is provided with two limiting strips, and the inner wall of the sliding block 11 is provided with two limiting strips. The limiting groove cooperates with the positioning bar to prevent the sliding block 11 from disengaging from the slide rail 12 during movement; a hydraulic rod 13 is fixedly connected to the side wall of the fixing plate 10, which provides driving force to the locking block 14 to realize the lifting and lowering action of the locking block 14. The output end of the hydraulic rod 13 is fixedly connected to the locking block 14, which locks the adjusted paper pressing structure by abutting against the external structure; the top of the locking block 14 is provided with anti-slip texture, which increases the friction between the locking block 14 and the external structure and improves the locking stability.

[0025] In this invention, when stacked paper is conveyed, the top of the stacked paper first contacts the multiple pressure rollers 8 on the right side. When the stacked paper contacts the bottom of the multiple pressure rollers 8, it drives the pressure rollers 8 to rotate, thus achieving the purpose of smooth paper feeding (this device uses multiple pressure rollers 8 and elastic sheets 7 to buffer the impact of changes in paper thickness on paper feeding). When the paper feeding position needs to be adjusted, two sliding blocks 11 slide on the slide rail 12. During this process, the fixed plate 10, wall plate 1, straight arm 2, and multiple pressure rollers 8 move along the axial direction of the slide rail 12 until the multiple pressure rollers 8 are adjusted to a suitable position. The hydraulic rod 13 is activated, and the output end of the hydraulic rod 13 drives the locking block 14 to move upward until the top of the locking block 14 abuts against the roof, thus locking the position of the fixed plate 10, wall plate 1, straight arm 2, and multiple pressure rollers 8.

[0026] This device can adjust the horizontal distance between the two U-shaped seats 3, thereby adjusting the distance between each paper pressing roller 8: the operator loosens the fastening bolt 4, then adjusts the distance between each U-shaped seat 3, and then tightens the fastening bolt 4 to fix the U-shaped seats 3; by adjusting the distance between multiple U-shaped seats 3, i.e. multiple paper pressing rollers 8, the device can meet the paper pressing requirements of different paper lengths.
