Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard box technology, specifically a corrugated cardboard box creasing device. Background Technology

[0002] Corrugated cardboard is die-cut, creasing, and stapling or gluing to make corrugated boxes. Corrugated boxes are one of the most widely used packaging products, and their usage has always been the highest among all packaging products, including calcium-plastic corrugated boxes. For more than half a century, corrugated boxes have gradually replaced wooden boxes and other transport packaging containers due to their superior performance and good processing properties, becoming the mainstay of transport packaging. In addition to protecting goods and facilitating warehousing and transportation, they also beautify and promote goods. Corrugated boxes are green and environmentally friendly products, which are beneficial to the environment and facilitate loading, unloading and transportation.

[0003] Traditional corrugated cardboard boxes cannot be effectively positioned during creasing operations. The box may shift laterally, longitudinally, or in the rotational direction during the creasing process, causing the creasing line to deviate from the design position, become skewed, and affect the folding and forming effect of the cardboard box. This increases the difficulty of subsequent processing (such as folding and gluing), and may even lead to scrap, unqualified product appearance, and affect packaging quality. To address these issues, we have proposed a corrugated cardboard box creasing device. Utility Model Content

[0004] The purpose of this invention is to provide a corrugated cardboard box creasing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a corrugated cardboard box creasing device, comprising a base, with limiting components engaged at both the left and right ends of the base, each limiting component including a fixing plate. The fixing plates are engaged at both the left and right ends of the base, and a first connecting plate is fixedly connected to the upper end of each fixing plate. A fixing rod is fixedly connected to the first connecting plate, and springs are sleeved at both the front and rear ends of the fixing rod. A connecting sleeve is sleeved at the middle position of the fixing rod, and a limiting plate is fixedly connected to the connecting sleeve. A second connecting plate is fixedly connected to both the front and rear ends of the base, and a first connecting rod is fixedly connected to the second connecting plate. A first fixing sleeve is sleeved on the first connecting rod, and a connecting frame is fixedly connected to the upper end of the first fixing sleeve. A second connecting rod is fixedly connected to the upper end of the connecting frame, and a second fixing sleeve is sleeved on the second connecting rod. A cylinder is fixedly installed at the lower end of the second fixing sleeve, and an mounting plate is fixedly connected to the lower end of the cylinder. A pressure block is fixedly installed at the lower end of the mounting plate by bolts. Laser markers are fixedly installed at both the front and rear ends of the lower surface of the mounting plate.

[0006] Preferably, the lower end of the fixing plate is movably engaged with the base by a T-shaped locking block, and the base is provided with a T-shaped locking groove that cooperates with the T-shaped locking block.

[0007] Preferably, both ends of the spring are fixedly connected to the first connecting plate and the connecting sleeve, the lower end of the limiting plate is provided with a V-shaped structure, a rubber pad is fixedly connected to the lower end of the limiting plate, and the lower surface of the limiting plate abuts against the base.

[0008] Preferably, the first fixing sleeve is movably fitted onto the first connecting rod, a locking bolt is inserted into the front surface of the first fixing sleeve, and locking grooves that cooperate with the locking bolt are evenly opened on the first connecting rod.

[0009] Preferably, the second connecting rod is configured in a cross shape, the second fixing sleeve is movably sleeved on the second connecting rod, a locking bolt is inserted into the upper end of the second fixing sleeve, and locking grooves that cooperate with the locking bolts are evenly opened on the second connecting rod.

[0010] Preferably, both the pressure block and the mounting plate are provided with threaded slots that mate with bolts, and a washer is fitted onto the bolt.

[0011] Preferably, the lower end of the pressure block is provided with a V-shaped structure.

[0012] This utility model provides a corrugated cardboard box creasing device, which has the following beneficial effects:

[0013] By fixing a T-shaped locking block to the lower end of the fixed plate, the entire limiting assembly can be moved by the T-shaped locking block. The limiting assembly can be moved to a suitable position according to the width of different cartons, which increases the practicality of the device during use. Lifting the limiting plate allows the carton to be placed on the base. Releasing the limiting plate allows the fixing sleeve to reset through the spring force, which in turn drives the limiting plate to reset. When the lower end of the limiting plate abuts against the carton, it limits the carton and prevents the carton from moving. This ensures that the creasing wheel or creasing die applies pressure evenly, resulting in a consistent creasing depth and avoiding localized excessive or shallow creasing. This protects the integrity of the corrugated paper structure and improves the strength of the carton.

[0014] The pressure block is fixed to the mounting plate by bolts. The bolts can be rotated to unlock the mounting plate and pressure block, allowing the pressure block to be disassembled. The pressure block can be replaced according to different needs. The cylinder drives the mounting plate and pressure block to move up and down, realizing automated creasing. The laser marker projects positioning lines in front of the creasing, assisting the operator to quickly adjust the position of the carton, reducing manual intervention. The creasing process is efficient and standardized, and the laser marking provides visual guidance, further reducing the difficulty of operation and time costs. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5This utility model provides a technical solution: a corrugated cardboard box creasing device, including a base 1, with limiting components engaged at both ends of the base 1. Each limiting component includes a fixing plate 2. The fixing plates 2 are engaged at both ends of the base 1, and a first connecting plate 3 is fixedly connected to the upper end of the fixing plate 2. A fixing rod 4 is fixedly connected to the first connecting plate 3, and springs 5 ​​are sleeved at both ends of the fixing rod 4. A connecting sleeve 6 is sleeved at the middle position of the fixing rod 4, and a limiting plate 7 is fixedly connected to the connecting sleeve 6. Second connecting plates 8 are fixedly connected to both ends of the base 1. A first connecting rod 9 is fixedly connected to the second connecting plate 8. A first fixing sleeve 10 is sleeved on the first connecting rod 9. A connecting frame 11 is fixedly connected to the upper end of the first fixing sleeve 10. A second connecting rod 12 is fixedly connected to the upper end of the connecting frame 11. A second fixing sleeve 13 is sleeved on the second connecting rod 12. A cylinder 14 is fixedly installed at the lower end of the second fixing sleeve 13. A mounting plate 15 is fixedly connected to the lower end of the cylinder 14. A pressure block 16 is fixedly installed at the lower end of the mounting plate 15 by bolts. Laser markers 17 are fixedly installed at both the front and rear ends of the lower surface of the mounting plate 15.

[0024] The lower end of the fixed plate 2 is movably engaged with the base 1 via a T-shaped locking block. The base 1 has a T-shaped slot that mates with the T-shaped locking block, allowing for quick adjustment of the position of the limiting component according to the carton size, adapting to the production needs of different carton specifications. Both ends of the spring 5 are fixedly connected to the first connecting plate 3 and the connecting sleeve 6. The lower end of the limiting plate 7 has a V-shaped structure, and a rubber pad is fixedly connected to the lower end of the limiting plate 7. The lower surface of the limiting plate 7 abuts against the base 1. Both ends of the spring 5 are fixed to the first connecting plate 3 and the connecting sleeve 6 respectively. The elastic deformation of the spring 5 provides buffering force. The rubber pad at the lower end of the limiting plate 7 contacts the carton, reducing friction and collision. The elasticity of the spring 5 absorbs the positioning impact force of the carton, preventing rigid limiting from causing indentations or wear on the edges and corners of the carton. The rubber pad increases... Friction prevents the carton from sliding during creasing and protects the carton surface from scratches. The lower end of the limiting plate 7 has a V-shaped structure that abuts against the base 1, forming a stable support. The V-shaped structure can automatically adapt to cartons of different thicknesses, and the limiting height adjusts with the carton thickness, eliminating the need for frequent adjustments to the height of the limiting plate 7. This makes it suitable for corrugated cartons of different specifications. The V-shaped structure disperses pressure, avoids local stress concentration, and improves limiting stability. The limiting plate 7, through the cooperation of the spring 5 and the connecting sleeve 6, always abuts against the side of the carton. The T-shaped slot on the base 1 restricts the left and right movement of the fixing plate 2, ensuring that the position of the limiting plate 7 is fixed. The carton is firmly fixed in the preset position during creasing, avoiding lateral or longitudinal displacement. Precise limiting ensures accurate creasing position and improves product qualification rate.

[0025] The first fixing sleeve 10 is movably fitted onto the first connecting rod 9. A locking bolt is inserted into the front surface of the first fixing sleeve 10. The first connecting rod 9 has evenly spaced locking grooves that mate with the locking bolts. The second connecting rod 12 has a cross-shaped structure. The second fixing sleeve 13 is movably fitted onto the second connecting rod 12. A locking bolt is inserted into the upper end of the second fixing sleeve 13. The second connecting rod 12 has evenly spaced locking grooves that mate with the locking bolts. Both the pressure block 16 and the mounting plate 15 have threaded slots that mate with bolts. Washers are fitted onto the bolts. The lower end of the pressure block 16 has a V-shaped structure. The first fixing sleeve 10 and the second fixing sleeve 13, through the locking bolts, engage with the locking grooves on the first connecting rod 9 and the second connecting rod 12, allowing for quick and easy fastening. The locking grooves evenly distributed on the first connecting rod 9 and the second connecting rod 12 allow the first fixing sleeve 10 and the second fixing sleeve 13 to stay in multiple positions to meet the needs of different creasing positions. According to the carton size or creasing position requirements, the height and position of the pressure block 16 can be quickly adjusted without complex tools. The locking mechanism ensures the stability of the adjusted position and prevents displacement during creasing. The second connecting rod 12 is designed in a cross shape, which cooperates with the second fixing sleeve 13 to form a stable support frame. The cross shape balances the force on the pressure block 16, preventing tilting or shaking during creasing, improving the stability of the creasing process, ensuring uniform pressure on the pressure block 16, and preventing creasing skew. The cross shape distributes pressure and reduces the need for the second connecting rod 12 to move. 2. To mitigate deformation risks and extend equipment lifespan, the lower end of the pressure block 16 features a V-shaped structure, ensuring a tight fit with the corners or creases of the carton. The V-shaped design concentrates pressure, ensuring clear and consistent crease depth, precisely pressing the carton corners and preventing blurry or misaligned creases. The V-shaped pressure block 16 is suitable for cartons of varying thicknesses, exhibiting strong adaptability. Threaded slots are provided on the pressure block 16 and mounting plate 15, secured with bolts and washers. The washers distribute bolt pressure, preventing deformation of the pressure block 16 or mounting plate 15. The pressure block 16 can be quickly disassembled and replaced, facilitating the selection of different shapes based on carton specifications or crease requirements. The bolts provide a secure fixation, and the washers protect the material surface, preventing damage due to overtightening. The first fixing sleeve 10 and the second fixing... The fixed sleeve 13 can be independently adjusted or replaced by engaging with the connecting rod via a locking bolt. The cross-shaped second connecting rod 12 and the V-shaped pressure block 16 both adopt a modular design, which facilitates maintenance. During equipment maintenance, faulty modules can be quickly disassembled, reducing downtime. The modular design reduces maintenance difficulty and saves maintenance costs. The locking mechanism of the first fixed sleeve 10 and the second fixed sleeve 13 ensures that the pressure block 16 is perpendicular to the carton surface. The cross-shaped second connecting rod 12 balances the pressure distribution, avoids excessive local pressure, ensures uniform indentation depth, prevents local crushing of the carton or unclear indentation, improves indentation quality, and reduces scrap rate. The multi-position design of the locking groove, the self-adaptive capability of the V-shaped pressure block 16, and the flexibility of bolt fixing make the equipment compatible with cartons of different specifications.

[0026] Working principle: The carton is placed on the base 1. The limiting components (limiting plate 7, spring 5) automatically fix the carton horizontally to prevent it from shifting. The laser marker 17 projects positioning lines to assist in adjusting the position of the carton. According to the carton specifications, the positions of the first fixing sleeve 10 and the second fixing sleeve 13 are adjusted to lock the height of the pressure block 16. The cylinder 14 is activated to drive the pressure block 16 to move downward and crease the carton. The V-shaped pressure block 16 concentrates the pressure to ensure that the creases are clear and the depth is uniform. The cylinder 14 is reset, the pressure block 16 is lifted, and the creased carton is taken out.
