Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of paper box processing, and more particularly to a paper box processing gluing and edging device with high stability. BACKGROUND

[0002] As the core carrier of modern commodity packaging, a paper box is usually composed of a face paper and a main structure. The face paper, as the outer decorative and protective material, is closely attached to the surface of the main structure composed of cardboard, corrugated paper or multi-layer composite paper board through the pasting process to form a packaging product with both aesthetic and functional properties. The main processing equipment for producing paper boxes includes automatic pasting machines, die-cutting machines and edging forming devices. The gluing and edging process is the key link to determine the sealing and structural stability of the paper box. In the traditional pasting equipment, the pre-cut paper blank is conveyed to the gluing station by a conveyor belt, and the adhesive is applied at the preset position by a glue gun or glue roller mechanism. Then the adhesion and corner shaping of the face paper and the main structure are completed by the mechanical folding and pressing module.

[0003] The existing equipment has the following defects: In the process of pasting the face paper to the main structure, multiple pressing plate mechanisms are generally used to apply vertical pressure to the adhesion area to ensure the adhesion strength. However, the mechanical connection between the pressing plate units causes unavoidable small gaps between the edges of adjacent pressing plates, usually reaching 0.5 to 1.2 mm. The gap forms a local pressure-free area under the action of continuous pressure, causing uneven pressure distribution at the adhesion site of the paper box side wall. Air bubbles or virtual connection of the adhesive layer may occur between the face paper and the main structure in the area without pressure, resulting in warping of the paper box corners, reduced sealing performance and even reduced overall compressive strength.

DETAILED DESCRIPTION

[0034] In order to make the technical problems, technical solutions and beneficial effects of the present application more clearly understood, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0035] Reference Figure 1 and Figure 8 Now a paper box processing gluing and edge rolling device with high stability provided by the present application will be described.

[0036] The paper box processing gluing and edge rolling device with high stability provided by the embodiment comprises a body 1, an inner support mechanism 2 and a pressure applying mechanism 3 mounted on the body 1. A paper box cover is arranged on the inner support mechanism 2, and the inner support mechanism 2 is used to provide support for the paper box.

[0037] The pressure applying mechanism 3 comprises a side pressure applying assembly 31 and a corner pressure applying assembly 32 arranged on the machine body 1; the side pressure applying assembly 31 comprises a first telescopic piece 311 fixedly connected to the machine body 1 and a pressure applying plate 312 fixedly connected to the first telescopic piece 311; the corner pressure applying assembly 32 comprises a second telescopic piece 321 fixedly connected to the machine body 1 and a pressure applying piece 322 fixedly connected to the second telescopic piece 321. The pressure applying piece 322 is provided with a receiving cavity, and the corners of the carton can be attached to the inner wall of the receiving cavity; when the pressure applying mechanism 3 applies pressure to the carton, the pressure applying plate 312 and the pressure applying piece 322 are attached to the outer side wall of the carton and abut against each other, and the adjacent pressure applying plate 312 and pressure applying piece 322 jointly apply pressure to the outer side wall of the carton.

[0038] The paper box processing gluing and edge rolling device with high stability has the advantages that, compared with the prior art, in the paper box processing gluing and edge rolling device with high stability, the side pressure applying assembly 31 and the corner pressure applying assembly 32 jointly apply pressure to the carton during the pasting process, the side pressure applying assembly 31 applies pressure to most of the side wall of the carton, and the corner pressure applying assembly 32 applies pressure to the corner area of the carton. Through the cooperation of the side pressure applying assembly 31 and the corner pressure applying assembly 32, the corner blind area of the carton is eliminated, the corners and sides of the carton can be effectively and uniformly pressed, the local pressure-free area of the carton is eliminated, and the quality of the carton is improved.

[0039] In a possible implementation, the side pressure applying assembly 31 is provided with five side pressure applying assemblies 31 corresponding to the five sides of the carton one by one, the first telescopic piece 311 is perpendicular to the side wall of the carton, and the pressure applying plate 312 is parallel to the side wall of the carton.

[0040] In a possible implementation, the corner pressure applying assembly 32 is provided with four corner pressure applying assemblies 32 arranged above the four corners of the carton obliquely and located on the extension lines of the four diagonal lines of the carton, and the second telescopic piece 321 is arranged along the extension lines of the diagonal lines of the carton.

[0041] In a preferred embodiment, the shape of the pressing plate 312 is similar to the shape of the outer side wall of the carton, and the size of the pressing plate 312 is smaller than the size of the outer side wall of the carton. The first telescopic member 311 is perpendicular to the pressing plate 312 and the side wall of the carton, one end of the first telescopic member 311 is connected to the central region of the pressing plate 312, and the first telescopic member 311 and its extension line pass through the pressing plate 312 and the side wall of the carton once. The pressing member 322 includes a first part, a second part and a third part perpendicular to each other, the first part, the second part and the third part are arranged along the X axis, the Y axis and the Z axis of the Cartesian coordinate system respectively, and the first part, the second part and the third part meet and are fixedly connected at the origin position of the Cartesian coordinate system. The lengths of the first part, the second part and the third part are half of the length, width and height of the carton respectively. The shape of one pressing plate 312 and two adjacent pressing members 322 spliced together is the same as the shape of one side of the carton, so one pressing plate 312 and two adjacent pressing members 322 together press one side wall of the carton. Both the side of the carton and the corner position of the carton can be pressed, eliminating the pressure blind area and solving the defect of local pressure-free area in the carton pasting process in the prior art.

[0042] In a preferred embodiment, the first telescopic member 311 and the second telescopic member 321 have the same structure, which is a gas cylinder. The main structure includes a cylinder, a piston, a piston rod, an end cover and a sealing assembly. The cylinder is a cylindrical hollow shell, the inner wall of which is precisely machined to reduce friction, and the material is mostly aluminum alloy, stainless steel or engineering plastic, ensuring light weight and corrosion resistance. The piston is the core moving part inside the cylinder, usually made of metal or composite material, tightly fitted with the inner wall of the cylinder, and reciprocating through the pressure difference. The piston rod is fixed to the piston at one end and extends out of the cylinder to connect the external load, and needs to have high strength and wear resistance, usually treated with hard chromium plating process. The two end covers are connected with the cylinder through bolts or snap rings to form a sealed chamber, and some designs include a buffer device to absorb the impact force when the piston moves to the end of the stroke. The sealing assembly includes a piston sealing ring, a rod end sealing ring and a dust seal, which are mostly made of oil-resistant rubber or polyurethane to ensure air tightness and prevent external contaminants from entering, and their performance directly affects the efficiency and life of the cylinder.

[0043] The air cylinder has simple and compact structure, convenient installation and maintenance, and does not need a complex lubrication system. The air cylinder can realize high-speed response and frequent start-stop by air pressure driving, and the action speed can reach several meters per second. By adjusting the air inlet pressure and flow, the output force and movement speed can be accurately controlled, and the air cylinder has an overload protection feature. When the external force exceeds the limit, the piston stops automatically to avoid equipment damage. The air cylinder has strong adaptability. The double-acting type realizes bidirectional movement by alternating air supply, the single-acting type relies on spring return, and the rodless air cylinder eliminates the piston rod through magnetic or mechanical structure, which is suitable for space-limited scenes. The high-temperature-resistant, explosion-proof and corrosion-resistant models can adapt to dusty, humid or flammable and explosive environments. In addition, the air cylinder combined with solenoid valves, sensors and other elements can accurately realize position detection and automatic program control, and become a key power unit in modern production lines, mechanical hands and clamping mechanisms. Although the output force is limited by air pressure and low-speed movement is prone to crawling, its high cost performance and reliability make it irreplaceable in the industrial field.

[0044] In a preferred embodiment, the first telescopic member 311 and the second telescopic member 321 have the same structure, both of which are electric telescopic rods. The electric telescopic rod is a device that realizes linear telescopic movement by electric power driving. The core structure includes a motor, a transmission mechanism, a telescopic rod body, and a control module. The motor, usually a DC motor, a stepper motor, or a servo motor, can output stable rotary torque; the transmission mechanism converts the rotary motion of the motor into linear motion, common forms include ball screws, planetary gear sets, or synchronous belts, among which ball screws are widely used due to their high precision and low friction characteristics. The telescopic rod body is composed of multiple nested metal sleeves, made of aluminum alloy or stainless steel, with guide grooves and limiting structures inside to ensure the straightness and stability of the telescopic trajectory. The rod body is equipped with a flange or threaded interface at the end for easy connection to external loads. The control module is integrated in the motor housing or independently packaged, with built-in drive circuit, encoder, and microprocessor, which adjusts the telescopic speed, stroke, and output force by receiving pulse signals or analog command instructions. Some high-end models also have built-in displacement sensors and force feedback elements to monitor position and load status in real time, and are connected to PLC and Internet of Things systems for intelligent control.

[0045] In a possible implementation, the pressing mechanism 3 further comprises a fine adjustment assembly for adjusting the pressure exerted by the pressing plate 312 and the pressing member 322 on the side wall of the paper box; the fine adjustment assembly comprises a first air bag 33 fixedly connected to the side of the pressing plate 312 or the inner wall of the pressing member 322; when the pressure inside the first air bag 33 changes, the first air bag 33 expands or shrinks.

[0046] In a possible implementation, the inner support mechanism 2 comprises a support 21 and a second air bag 22. The support 21 is fixedly connected to the body 1. The second air bag 22 is fixedly connected to the side wall of the support 21. When the pressure inside the second air bag 22 changes, the second air bag 22 expands or shrinks.

[0047] In a possible implementation, a gas bag 23 is arranged on each of the top corners of the support 21. The gas bag 23 is arranged between the second air bags 22. The gas bag 23 is inelastic. When the pressure inside the gas bag 23 changes, the gas bag 23 unfolds or folds.

[0048] The volume of the support 21 and the initial volume of the second air bag 22 are slightly smaller than the internal volume of the carton. Therefore, when the carton cover is arranged on the support 21, a gap is left between the second air bag 22 and the inner wall of the carton. At this time, the pressure inside the second air bag 22 increases, and the volume expands, so that the second air bag 22 gradually fits the inner wall of the carton, and the second air bag 22 applies a certain pressure to the inner wall of the carton to provide inner support for the carton. The gas bag 23 is a plastic bag with thin thickness, soft texture, poor variability and poor elasticity. After the gas bag 23 is inflated, the pressure increases, the gas bag 23 gradually expands and unfolds, and when the pressure inside the gas bag 23 decreases, the volume shrinks and folds together. After the second air bag 22 expands, the edge line of the second air bag 22 becomes a curved surface, so that the four corners and the edge line inside the carton are not supported by the second air bag 22. At this time, the gas bag 23 is inflated, so that the pressure inside the gas bag 23 increases, the side wall of the gas bag 23 unfolds, and under the action of the gas pressure, the side wall of the gas bag 23 fits the edge line and the four corners on the inner wall of the carton, and at the same time, the gas pressure inside the gas bag 23 supports the edge line and the four corners of the inner wall of the carton.

[0049] In a possible implementation, a gas pump and a heating mechanism are further included. The gas pump is connected to the first air bag 33, and the heating mechanism is arranged between the gas pump and the first air bag 33. The heating mechanism is used to heat the gas entering the first air bag 33 to control the temperature of the first air bag 33.

[0050] In a possible implementation, a pressure sensor is arranged between the first telescopic member 311 and the pressing block and between the second telescopic member 321 and the pressing member 322. The pressure sensor is used to detect the pressure applied by the pressing mechanism 3 to the carton and output pressure information.

[0051] In a possible implementation, a control module in communication connection with the pressure sensor and the heating mechanism is further included. After the control module obtains the type information of the carton, the control module controls the temperature of the first air bag 33 and the pressure applied by the pressing mechanism 3 to the carton.

[0052] In a possible implementation, after the control module obtains the kind information of the carton, it obtains the target pressure information and the target temperature information; after the control module receives the pressure information, it compares the pressure information with the target pressure information, and controls the pressure inside the first air bag 33 according to the comparison result; the control module sends the target temperature information to the heating mechanism, so that the heating mechanism controls the temperature of the first air bag 33.

[0053] The control module is built-in a database, which stores the pressure that various carton materials can bear when pasting the carton, and the temperature required by various glues when curing. When pasting the carton, the control module first obtains the material of the carton and the material of the glue, so as to obtain the pressure that the carton can bear and the temperature required by the glue when curing from the database, and takes the pressure and the temperature as the target pressure and the target temperature. During the pasting process, after the control module receives the pressure information, it compares the pressure information with the target pressure, if the pressure information is less than the target pressure, it increases the pressure of the first air bag 33, so as to increase the pressure applied to the carton by the pressing mechanism 3. If the pressure information is greater than the target pressure, it decreases the pressure of the first air bag 33, so as to decrease the pressure applied to the carton by the pressing mechanism 3. If the pressure information is equal to the target pressure, it controls the first air bag 33 to maintain the current pressure. At the same time, the control module sends the target temperature to the heating mechanism. The heating mechanism is built-in a microprocessor and a temperature sensor. The temperature sensor monitors the temperature of the airflow supplied to the inside of the first air bag 33 in real time, and sends the temperature information to the microprocessor. The microprocessor compares the temperature information with the target temperature, if the temperature information is lower than the target temperature, it controls the heating mechanism to increase the power, so as to increase the temperature of the airflow. If the temperature information is higher than the target temperature, it controls the heating mechanism to decrease the power or stop working, so as to decrease the temperature of the airflow. If the temperature information is equal to the target temperature, it controls the heating mechanism to maintain the current power, so as to maintain the temperature of the airflow.

[0054] The above merely provides the preferred embodiments of the present application, but should not be used to limit the present application, and any modification, equivalent replacement, and improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
