Description
Technical Field
[0001] This utility model relates to the field of creasing machine technology, and in particular to a creasing device for corrugated paper for corrugated boxes. Background Technology
[0002] In the production and processing of corrugated cardboard boxes, precise creasing of the corrugated paper is a crucial step to ensure the quality of subsequent folding and forming. The accuracy of the creasing directly affects the overall structural stability and appearance regularity of the corrugated cardboard box. Currently, although creasing machines on the market can achieve basic creasing functions, they still have significant shortcomings in the feeding and positioning of corrugated paper of different specifications. Most existing creasing machines have fixed-size conveying mechanisms, and parameters such as the width of the conveying channel and the spacing of the positioning components are difficult to adjust flexibly according to the actual size of the corrugated paper being processed. When creasing corrugated paper of different sizes is required, the paperboard is prone to deviation and skewing during the conveying process. This unstable positioning will directly cause the creasing position to deviate from the preset trajectory, which will not only affect the folding accuracy of the corrugated paper, but also easily cause material waste, increase the workload of subsequent correction processes, and in severe cases, even reduce the production qualification rate of corrugated boxes, making it difficult to meet the needs of modern corrugated box production for efficient and precise processing of products of different specifications. Utility Model Content
[0003] This utility model addresses the shortcomings of existing technologies by providing a corrugated paper creasing device for corrugated cardboard boxes. The specific technical solution is as follows: A corrugated paper creasing device for corrugated boxes includes a creasing machine body with a creasing roller on it. A feed plate is fixedly installed at one end of the creasing machine body, and fixed frames are fixedly installed at opposite ends of the feed plate. Two sets of guide rods are fixedly installed between the fixed frames. A second sliding seat is slidably installed on the outer surface of each set of guide rods, and a limit plate is fixedly installed at the bottom of the second sliding seat. An adjustment component is provided on each of the two sets of limit plates for using corrugated paper of different thicknesses. A drive component is provided on the feed plate for controlling the two sets of limit plates to slide synchronously along the length of the guide rods to adjust the spacing.
[0004] As an improvement to the above technical solution, two sets of mounting slots are provided on the two sets of limiting plates. The adjustment component includes an electric push rod fixedly installed on the top of the two sets of limiting plates. The bottom end of the output shaft of the electric push rod passes through the mounting slot, and a connecting rod is fixedly connected to the bottom end of the output shaft of the electric push rod. An adjustment plate is fixedly installed on the connecting rod.
[0005] As an improvement to the above technical solution, multiple sets of rotating shafts are rotatably mounted on the bottom end of the adjustment plate.
[0006] As an improvement to the above technical solution, both sets of fixed frames are fixedly mounted with bidirectional lead screws by bearings. The outer surface of the bidirectional lead screw is slidably fitted with two sets of first sliding seats. The bottom ends of the two sets of first sliding seats are fixedly connected with limit plates. The ends of the bidirectional lead screws are fixedly mounted with second grooved wheels.
[0007] As an improvement to the above technical solution, the drive assembly includes a connecting frame fixedly installed at the bottom of the feed plate, and a servo motor is fixedly installed on the connecting frame. A first grooved wheel is fixedly connected to the output shaft of the servo motor, and pulleys are sleeved on the first grooved wheel and the second grooved wheel.
[0008] As an improvement to the above technical solution, a protective cover is fixedly installed on one side of the feed plate.
[0009] As an improvement to the above technical solution, protective shells are fixedly installed on the two aforementioned mounting brackets.

Detailed Implementation
[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0014] Example For corrugated cardboard box creasing devices, please refer to [reference needed]. Figures 1-6 The system includes a creasing machine body 1, a creasing roller 11 mounted on the creasing machine body 1, a feed plate 2 fixedly mounted at one end of the creasing machine body 1, and fixed frames 3 fixedly mounted at opposite ends of the feed plate 2. Two sets of guide rods 62 are fixedly mounted between the fixed frames 3. A second sliding seat 61 is slidably mounted on the outer surface of each of the two sets of guide rods 62, and a limit plate 6 is fixedly mounted at the bottom end of the second sliding seat 61. The limit plate 6 can stably limit the cardboard from both sides, preventing the cardboard from shifting laterally during transport. This directly reduces the creasing misalignment problem caused by the cardboard position deviation, improves the accuracy of creasing, and thus ensures the accuracy of subsequent folding and forming of corrugated boxes, reducing material waste caused by creasing deviation. Adjustment components are provided on the two sets of limit plates 6, which are used to use corrugated paper of different thicknesses. A drive component is provided on the feed plate 2, which is used to control the two sets of limit plates 6 to slide synchronously along the length direction of the guide rods 62 to adjust the spacing.
[0015] like Figure 4 As shown, two sets of mounting slots 84 are provided on the two sets of limiting plates 6. The adjustment assembly includes an electric push rod 8 fixedly installed on the top of the two sets of limiting plates 6. The bottom end of the output shaft of the electric push rod 8 passes through the mounting slot 84, and a connecting rod 81 is fixedly connected to the bottom end of the output shaft of the electric push rod 8. An adjusting plate 82 is fixedly installed on the connecting rod 81. The electric push rod 8 can drive the connecting rod 81 and the adjusting plate 82 to move up and down, so that the adjusting plate 82 contacts the top surface of the cardboard and forms pressure. For thicker cardboard, the adjusting plate 82 can be controlled to move upward to leave enough space; for thinner cardboard, the adjusting plate 82 can be moved downward to effectively limit it.
[0016] like Figure 4 As shown, multiple sets of rotating shafts 83 are rotatably installed at the bottom of the adjusting plate 82. The rotating shafts 83 rotate synchronously with the paperboard during the paperboard conveying process, converting sliding friction into rolling friction, which greatly reduces the resistance to paperboard conveying. This not only ensures the stability of paperboards of different thicknesses during the conveying process and avoids creasing deviation caused by vertical movement, but also ensures the smoothness of the conveying process, preventing the paperboard from wrinkling or breaking due to excessive resistance, thus improving creasing quality and production efficiency.
[0017] like Figure 3As shown, both sets of fixed frames 3 are fixedly mounted with bidirectional lead screws 7 via bearings. Two sets of first sliding seats 71 are slidably sleeved on the outer surface of the bidirectional lead screws 7. The bottom ends of the two sets of first sliding seats 71 are fixedly connected to limit plates 6. The ends of the bidirectional lead screws 7 are fixedly mounted with second grooved wheels 94. When the bidirectional lead screws 7 rotate, the two sets of first sliding seats 71 will move in opposite directions due to the thread characteristics of the lead screw, thereby driving the limit plates 6 to move synchronously to adjust the spacing. The adjustment method through lead screw transmission is more precise and allows for more accurate adjustment of the spacing of the limit plates 6, ensuring precise matching with the width of the cardboard.
[0018] like Figure 4-5 As shown, the drive assembly includes a connecting frame 9 fixedly installed at the bottom of the feed plate 2, and a servo motor 91 is fixedly installed on the connecting frame 9. A first grooved wheel 92 is fixedly connected to the output shaft of the servo motor 91, and a pulley 93 is sleeved on the first grooved wheel 92 and the second grooved wheel 94. The servo motor 91 has the characteristics of high control precision and flexible speed adjustment, and can accurately control the rotation angle and speed of the first grooved wheel 92. In turn, it can accurately control the rotation of the bidirectional lead screw 7 through belt transmission, realize the precise adjustment of the spacing of the limit plate 6, and meet the adaptation requirements of different width cardboards.
[0019] like Figure 1 As shown, a protective cover 5 is fixedly installed on one side of the feed plate 2. The protective cover 5 can effectively protect the first grooved wheel 92, the second grooved wheel 94 and the pulley 93. It can prevent paper scraps, dust and other debris generated during the creasing process from adhering to the grooved wheel and the pulley 93, and prevent these debris from affecting the transmission effect between the grooved wheel and the pulley 93.
[0020] like Figure 1 As shown, protective shells 4 are fixedly installed on the two fixed frames 3. The protective shells 4 protect the bidirectional lead screw 7 and prevent external dust, impurities and paper scraps in the production environment from entering the thread gap of the bidirectional lead screw 7.
[0021] Working principle: Before creasing the corrugated paper, the device needs to be adjusted according to the size of the corrugated paper to be processed. After the corrugated paper is placed stably on the feed plate 2, the servo motor 91 is started. The output shaft of the servo motor 91 drives the first grooved wheel 92 to rotate synchronously. Since the first grooved wheel 92 and the second grooved wheel 94 are connected by the belt pulley 93, the rotational force of the first grooved wheel 92 is transmitted to the second grooved wheel 94 through the belt pulley 93, which in turn drives the bidirectional lead screw 7 to rotate along its own axis. When the bidirectional lead screw 7 rotates, the two sets of first sliding seats 71 on its outer surface move synchronously in opposite directions along the length of the lead screw due to the threaded engagement. At the same time, the second sliding seat 61 at the top of the limiting plate 6 slides synchronously along the guide rod 62. The guide rod 62 provides stable guidance for the movement of the limiting plate 6, preventing it from deviating or shaking during the sliding process. Through the cooperation of the two sets of sliding seats, the distance between the two sets of limiting plates 6 can be precisely adjusted to match the width of the corrugated paper, thereby forming a stable limit on the corrugated paper from both sides and preventing it from shifting laterally during the conveying process. For corrugated paper of different thicknesses, the adjustment components can be used to achieve adaptation. When the electric push rod 8 is activated, its output shaft drives the connecting rod 81 to move up and down along the mounting groove 84, which in turn drives the adjusting plate 82 to rise and fall synchronously until the rotating shaft 83 at the bottom of the adjusting plate 82 gently contacts the top surface of the corrugated paper. At this time, the rotating shaft 83 can limit the corrugated paper from the top to prevent it from moving up and down during transportation and causing creasing deviation. It can also rotate synchronously with the paperboard during the transportation of the corrugated paper to the creasing roller 11, using rolling friction to reduce the resistance to the transportation of the corrugated paper and ensure smooth and stable transportation. After the size adaptation adjustment is completed, the corrugated paper is manually pushed to move towards the creasing roller 11. After being guided by the double limiting plate 6 and the adjusting plate 82, it accurately enters the creasing area of the creasing roller 11 and finally completes the precise creasing operation.
[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
