Description

Technical Field

[0001] This utility model relates to the field of cardboard processing technology, and in particular to an automated creasing device for cardboard surfaces. Background Technology

[0002] Automated creasing equipment for cardboard surfaces is a type of machinery used to perform automated creasing on the surface of cardboard. Creasing can create marks or grooves on the surface of cardboard. These marks serve as guidelines for bending, allowing the cardboard to be bent precisely at preset positions and angles. This enables the precise shaping of packaging products such as cartons and boxes. Furthermore, creasing can create specific textures and patterns on the surface of the cardboard, increasing the texture and aesthetics of the product.

[0003] When the surface of cardboard is creasing by a creasing machine, the pressure plate used for creasing creates indentations on the surface of the cardboard under the drive of a hydraulic cylinder. During this process, impurities such as paper scraps and dust in the cardboard processing environment can easily adhere to the pressure plate. As the impurities adhere, they will hinder the full contact between the pressure plate and the surface of the cardboard, resulting in incomplete and shallow creasing, which in turn affects the forming effect of the product. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that impurities such as paper scraps and dust in the existing cardboard processing environment easily adhere to the pressing plate. As these impurities adhere, they hinder the full contact between the pressing plate and the cardboard surface, resulting in unclear and deep indentations, which in turn affects the forming effect of the product. Therefore, an automated cardboard surface indentation device is proposed.

[0005] To achieve the above objectives, the present invention employs the following technology: an automated creasing device for cardboard surfaces, comprising a base, a worktable on the top of the base, a frame on the worktable, and a mounting seat capable of being lifted and moved on the frame via a hydraulic cylinder, a pressure plate at the bottom of the mounting seat, a blowing assembly on one side of the frame, and an air-guiding assembly on the other side of the frame, wherein the blowing assembly and the air-guiding assembly form a high-speed axial airflow on the surface of the pressure plate.

[0006] As a further description of the above technical solution: the blower assembly includes a first fixing cover fixed to the frame by a first mounting plate, and a blower connected to the first fixing cover is provided on the first fixing cover.

[0007] As a further description of the above technical solution: a guide plate is provided on the first fixed cover facing the pressure plate, and the guide plate has a plurality of air guide holes arranged in an array.

[0008] As a further description of the above technical solution: the air guide hole is arranged in a frustum shape, and the cross-sectional area of ​​the end of the air guide hole facing the blower is larger than the cross-sectional area of ​​the end facing the pressure plate.

[0009] As a further description of the above technical solution: the air-expelling assembly includes a second fixed cover fixed to the frame by a second mounting plate, and an air-expelling fan connected to the second fixed cover is provided on the second fixed cover.

[0010] As a further description of the above technical solution: the blowing direction of the blower is the same as the air intake direction of the exhaust fan.

[0011] As a further description of the above technical solution: a dust suction cover is provided on the second fixed cover facing the pressure plate, and a filter screen is provided inside the second fixed cover.

[0012] As a further description of the above technical solution: the top of the mounting base is detachably connected to the output end of the hydraulic cylinder via a connecting plate, and the pressure plate is detachably connected to the mounting base via screws.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. By combining the blowing and air-guiding components, an axial airflow is formed on the surface of the pressure plate, which can blow away paper scraps, dust and other impurities attached to the surface of the pressure plate, thereby avoiding insufficient contact between the pressure plate and the paperboard surface, making the indentation of the pressure plate clear and deep enough, and ensuring the forming effect of the indented paperboard.

[0015] 2. By forming a high-speed airflow on the surface of the pressure plate, heat can be dissipated from the pressure plate, effectively reducing the heat generated by the pressure plate under high-speed and high-pressure working conditions, thereby greatly extending the service life of the indentation equipment.

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-7 This embodiment provides an automated creasing device for cardboard surfaces, including a base 1, a workbench 2 on the top of the base 1, a frame 3 on the workbench 2, and a mounting seat 5 that can be lifted and moved on the frame 3 via a hydraulic cylinder 4. A pressure plate 6 is provided at the bottom of the mounting seat 5. A blowing assembly 7 is provided on one side of the frame 3, and an air-guiding assembly 8 is provided on the other side of the frame 3. The blowing assembly 7 and the air-guiding assembly 8 form a high-speed axial airflow on the surface of the pressure plate 6.

[0027] In this invention, the creasing device is fixed in place by the base 1. The cardboard to be creasing is placed on the worktable 2 on top of the base 1. Then, the hydraulic cylinder 4 on the frame 3 is started. After the hydraulic cylinder 4 is started, its piston rod extends, which in turn drives the mounting seat 5 on the piston rod to descend. As the mounting seat 5 descends, the pressure plate 6 at the bottom of the mounting seat 5 contacts the cardboard on the worktable 2. As the hydraulic cylinder 4 continues to descend, the pressure plate 6 presses out indentations on the cardboard. During this process, the blowing assembly 7 and the air-guiding assembly 8 form a high-speed axial airflow on the surface of the pressure plate 6. On the one hand, this keeps the pressure plate 6 clean and prevents impurities from adhering to the pressure plate 6, which would lead to a decrease in creasing accuracy. On the other hand, it can dissipate heat and extend the service life of the pressure plate 6.

[0028] Specifically, such as Figures 3-6As shown, the blower assembly 7 includes a first fixing cover 71 fixed to the frame 3 by a first mounting plate 73, and a blower 72 connected thereto is provided on the first fixing cover 71.

[0029] The air-expelling assembly 8 includes a second fixed cover 81 fixed to the frame 3 via a second mounting plate 83. An air-expelling fan 82 is provided on the second fixed cover 81 and communicates with it. The air-blowing direction of the blower 72 is the same as the air-expelling direction of the air-expelling fan 82.

[0030] The blower 72 is fixed on one side of the frame 3 using the first mounting plate 73 on the first fixed cover 71, and the induced draft fan 82 is fixed on the other side of the frame 3 using the second mounting plate 83 on the second fixed cover 81. The blower 72 and the induced draft fan 82 blow and draw air in the same direction, thereby forming a high-speed axial airflow on the surface of the pressure plate 6. The high-speed axial airflow can blow away paper scraps, dust and other impurities attached to the surface of the pressure plate 6, avoiding the deterioration of the creasing accuracy caused by paper scraps, dust and other impurities attached to the pressure plate 6. At the same time, the flowing airflow can carry away the heat generated by the pressure plate 6 under high speed and high pressure, thereby reducing the wear of the pressure plate 6 and extending the service life of the pressure plate 6.

[0031] Specifically, such as Figure 4 and Figure 5 A guide plate 711 is provided on the first fixed cover 71 facing the pressure plate 6, and a number of air guide holes 712 are arranged in an array on the guide plate 711.

[0032] The air blown out by the hair dryer 72 can be blown out evenly after passing through the air guide hole 712 on the air guide plate 711, so that the blown air is more uniform and the airflow is more uniform on the surface of the pressure plate 6, ensuring that paper scraps, dust and other impurities attached to the pressure plate 6 can be blown away, thereby ensuring the accuracy of the indentation.

[0033] It should be noted that the air guide hole 712 is shaped like a frustum, and the cross-sectional area of ​​the end of the air guide hole 712 facing the blower 72 is larger than the cross-sectional area of ​​the end facing the pressure plate 6. The frustum-shaped air guide hole 712 can accelerate the airflow when the air is blown out, so that the air from the blower 72 can be accelerated when passing through the air guide hole 712, thereby increasing the flow speed of the airflow on the surface of the pressure plate 6, thus ensuring that paper scraps, dust and other impurities attached to the pressure plate 6 can be completely blown away.

[0034] Specifically, such as Figure 6 and Figure 7 As shown, a dust suction cover 811 is provided on the second fixed cover 81 facing the pressure plate 6, and a filter screen 812 is provided inside the second fixed cover 81.

[0035] The blower 72 blows air that removes paper scraps, dust and other impurities attached to the pressure plate 6. This airflow containing paper scraps, dust and other impurities is introduced into the second fixed cover 81 by the blower 82, and then filtered down by the filter screen 812 to avoid environmental pollution. The dust cover 811 can play a role in preventing backflow, preventing the airflow entering the second fixed cover 81 from flowing back, thereby ensuring that paper scraps, dust and other impurities can be fully filtered down by the filter screen 812.

[0036] It should be noted that the top of the mounting base 5 is detachably connected to the output end of the hydraulic cylinder 4 via a connecting plate, and the pressure plate 6 is detachably connected to the mounting base 5 via screws. This detachable connection allows for easy disassembly and maintenance of the pressure plate 6 of the indentation equipment, enabling regular maintenance and extending the service life of the indentation equipment.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
