Description

Technical Field

[0001] The present invention belongs to the technical field of carton processing, and more specifically, relates to a gluing and edge rolling device for carton processing with high stability. Background Art

[0002] As the core carrier of modern commodity packaging, the structure of a carton usually consists of a face paper and a main structure. As the outer decorative and protective material, the face paper needs to be closely adhered to the surface of the main structure composed of cardboard, corrugated paper or multi-layer composite cardboard through a pasting process, so as to form a packaging product with both aesthetics and functionality. The main processing equipment for producing cartons includes automatic carton gluing machines, die-cutting machines and edge rolling and forming devices. Among them, the gluing and edge rolling processes are the key links determining the sealing performance and structural stability of cartons. Traditional carton gluing equipment transports pre-cut paper blanks to the gluing station through a conveyor belt, applies adhesives at preset positions by a glue gun or a glue roller mechanism, and then completes the bonding of the face paper and the main structure and the corner shaping through mechanical folding and pressing modules.

[0003] The equipment in the prior art has the following defects: During the process of pasting the face paper to the main structure, multiple sets of pressing plate mechanisms are generally used to apply vertical pressure to the bonding area to ensure the bonding strength. However, the mechanical connection method between the pressing plate units results in inevitable tiny gaps at the edges of adjacent pressing plates, usually reaching 0.5 to 1.2 millimeters. Under the continuous pressure, these gaps form local non-pressurized areas, causing uneven pressure distribution at the bonding sites on the side walls of the carton. Bubbles or virtual joints in the glue layer are likely to occur between the face paper and the main structure in the non-pressurized areas, resulting in warping of the carton corners, decreased sealing performance and even reduced overall compressive strength of the carton. Summary of the Invention

Detailed implementation manners

[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention 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 invention and are not used to limit the present invention.

[0021] Refer to Figure 1 and Figure 8 , and now a carton processing gluing and edge rolling device with high stability provided by the present invention will be described.

[0022] A carton processing gluing and edge rolling device with high stability provided by this embodiment includes a body 1 and an inner support mechanism 2 and a pressing mechanism 3 installed on the body 1. The carton is covered on the inner support mechanism 2, and the inner support mechanism 2 is used to provide support for the carton.

[0023] The pressing mechanism 3 includes a side pressing component 31 and a corner pressing component 32 disposed on the machine body 1; the side pressing component 31 includes a first telescopic member 311 fixedly connected to the machine body 1 and a pressing plate 312 fixedly connected to the first telescopic member 311; the corner pressing component 32 includes a second telescopic member 321 fixedly connected to the machine body 1 and a pressing member 322 fixedly connected to the second telescopic member 321. An accommodating chamber is formed on the pressing member 322, and the corners of the paper box can be attached to the inner wall of the accommodating chamber; when the pressing mechanism 3 presses the paper box, the pressing plate 312 and the pressing member 322 are attached to the outer side wall of the paper box and are in abutment against each other, and the adjacent pressing plate 312 and pressing member 322 jointly press the outer side wall of a paper box.

[0024] The beneficial effect of a carton processing gluing and edge rolling device with high stability provided by the present invention is as follows: compared with the prior art, in the carton gluing process of the carton processing gluing and edge rolling device with high stability of the present invention, the side pressing component 31 and the corner pressing component 32 jointly press the paper box. The side pressing component 31 presses most of the area of the side wall of the paper box, and the corner pressing component 32 presses the corner area of the paper box. Through the cooperation of the side pressing component 31 and the corner pressing component 32, the paper box is pressed jointly, eliminating the corner blind area of the paper box, effectively pressing the corners and sides of the paper box evenly, eliminating the local non-pressing area of the paper box, and improving the quality of the paper box.

[0025] In a possible implementation manner, five side pressing components 31 are provided, and the five side pressing components 31 respectively correspond to the five sides of the paper box one by one. The first telescopic member 311 is perpendicular to the side wall of the paper box, and the pressing plate 312 is parallel to the side wall of the paper box.

[0026] In a possible implementation manner, four corner pressing components 32 are provided, and the four corner pressing components 32 are respectively disposed obliquely above the four corners of the paper box and are respectively located on the extension lines of the four diagonals of the paper box. The second telescopic member 321 is disposed along the extension line of the diagonal of the paper box.

[0027] In a preferred embodiment, the shape of the pressing plate 312 is similar to the shape of the outer sidewall of the paper box, and the size of the pressing plate 312 is smaller than that of the outer sidewall of the paper box. The first telescopic member 311 is perpendicular to the pressing plate 312 and the sidewall of the paper box. One end of the first telescopic member 311 is connected to the central area of the pressing plate 312, and the first telescopic member 311 and its extension line pass through the pressing plate 312 and the sidewall of the paper box once. The pressing member 322 includes a first part, a second part, and a third part that are perpendicular to each other. The first part, the second part, and the third part are respectively arranged along the X-axis, Y-axis, and Z-axis of the Cartesian coordinate system, 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 respectively half of the length, width, and height of the paper box. The shape formed by splicing one pressing plate 312 and two adjacent pressing members 322 is the same as the shape of one side surface of the paper box. Therefore, one pressing plate 312 and two adjacent pressing members 322 jointly apply pressure to one sidewall of the paper box. It can not only apply pressure to the side surface of the paper box, but also apply pressure to the corner positions of the paper box, eliminating the pressure application blind area and solving the defect of the existence of a local non-pressure area during the pasting process of the paper box in the prior art.

[0028] In a preferred embodiment, the first telescopic member 311 and the second telescopic member 321 have the same structure, both of which are cylinders. Its main structure consists of a cylinder barrel, a piston, a piston rod, end covers, and a sealing assembly. The cylinder barrel is a cylindrical hollow shell with an inner wall that has been precision machined to reduce friction. The material is mostly aluminum alloy, stainless steel, or engineering plastic to ensure lightweight and corrosion resistance. The piston is the core moving part inside the cylinder barrel. It is usually made of metal or composite materials and fits tightly with the inner wall of the cylinder barrel to achieve reciprocating motion through the air pressure difference. One end of the piston rod is fixed to the piston, and the other end extends out of the cylinder barrel to connect to an external load. It needs to have high strength and wear resistance and is often treated with a hard chromium plating process. The two end covers are connected to the cylinder barrel by bolts or snap rings to form a sealed chamber. 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 piston seals, rod end seals, and dust seals, which are mostly made of oil-resistant rubber or polyurethane to ensure airtightness and prevent external pollutants from invading. Its performance directly affects the efficiency and life of the cylinder.

[0029] The cylinder has a simple and compact structure, is convenient for installation and maintenance, and does not require a complex lubrication system. Driven by air pressure, it can achieve high-speed response and frequent start-stop, and the action speed can reach several meters per second. By adjusting the intake air pressure and flow rate, the output force and movement speed can be precisely controlled, and it has an overload protection feature - when the external force exceeds the limit, the piston automatically stops to avoid equipment damage. The cylinder has strong adaptability. The double-acting type realizes bidirectional movement by alternating air supply, the single-acting type relies on spring reset, and the rodless cylinder eliminates the piston rod through magnetic or mechanical structures, which is suitable for scenarios with limited space. High-temperature resistant, explosion-proof and corrosion-resistant models can adapt to dusty, humid or flammable and explosive environments. In addition, after the cylinder is combined with components such as solenoid valves and sensors, it can accurately achieve position detection and automated program control, and becomes a key power unit in modern production lines, robotic arms and clamping mechanisms. Despite the disadvantages of limited output force by air pressure and easy crawling during low-speed movement, its high cost performance and reliability make it irreplaceable in the industrial field.

[0030] 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. An electric telescopic rod is a device that realizes linear telescopic movement through electric drive. Its core structure includes a motor, a transmission mechanism, a telescopic rod body and a control module. The motor, as the power source, usually selects a DC motor, a stepper motor or a servo motor, which can output stable rotational torque; the transmission mechanism converts the rotational movement of the motor into a linear movement, and 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, and the material is mostly aluminum alloy or stainless steel. It is internally provided with a guide groove and a limit structure to ensure the straightness and stability of the telescopic trajectory. The end of the rod body is equipped with a flange or a threaded interface for easy connection of external loads. The control module is integrated in the motor housing or independently packaged, and is internally provided with a drive circuit, an encoder and a microprocessor. By receiving pulse signals or analog commands, it adjusts the telescopic speed, stroke and output force. Some high-end models also internally integrate a displacement sensor and a force feedback element to monitor the position and load status in real time, and are linked with PLC and Internet of Things systems to achieve intelligent control.

[0031] In a possible implementation manner, the pressing mechanism 3 further includes a fine-tuning component, and the fine-tuning component is used to adjust the pressure applied by the pressing plate 312 and the pressing member 322 on the side wall of the paper box; the fine-tuning component includes a first airbag 33 fixedly connected to the side surface of the pressing plate 312 or the inner wall of the pressing member 322; when the pressure inside the first airbag 33 changes, it expands or contracts.

[0032] In a possible implementation, the inner support mechanism 2 includes a support member 21 and a second airbag 22. The support member 21 is fixedly connected to the body 1. The second airbag 22 is fixedly connected to the side wall of the support member 21; when the pressure inside the second airbag 22 changes, the second airbag 22 expands or contracts.

[0033] In a possible implementation, airbags 23 are provided at the top corners of the support member 21. The airbags 23 are arranged between the second airbags 22. The airbags 23 do not have elasticity. When the pressure inside the airbags 23 changes, the airbags 23 unfold or fold.

[0034] The sum of the volume of the support member 21 and the initial volume of the second airbag 22 is slightly smaller than the internal volume of the paper box. Therefore, when the paper box is placed over the support member 21, there is a certain gap between the second airbag 22 and the inner wall of the paper box. At this time, the pressure inside the second airbag 22 increases and the volume expands, causing the second airbag 22 to gradually fit the inner wall of the paper box. The second airbag 22 exerts a certain pressure on the inner wall of the paper box to provide internal support for the paper box. The airbag 23 is a plastic bag with a relatively thin thickness, soft texture and poor elasticity. When the airbag 23 is inflated and the pressure increases, the airbag 23 gradually expands and unfolds. When the pressure inside the airbag 23 decreases, the volume contracts and folds together. After the second airbag 22 expands, the side line of the second airbag 22 becomes a curved surface, resulting in the four corners and side lines inside the paper box not being supported by the second airbag 22. At this time, the airbag 23 is inflated, causing the pressure inside the airbag 23 to increase. The side wall of the airbag 23 unfolds and fits the side lines and four corners on the inner wall of the paper box under the action of air pressure. At the same time, the air pressure inside the airbag 23 is used to provide support for the side lines and four corners of the inner wall of the paper box.

[0035] In a possible implementation, it further includes an air pump and a heating mechanism. The air pump is connected to the first airbag 33, and the heating mechanism is arranged between the air pump and the first airbag 33. The heating mechanism is used to heat the gas entering the first airbag 33 to control the temperature of the first airbag 33.

[0036] In a possible implementation, pressure sensors are provided between the first telescopic member 311 and the pressing block and between the second telescopic member 321 and the pressing member 322. The pressure sensors are used to detect the pressure exerted by the pressing mechanism 3 on the paper box and output pressure information.

[0037] In a possible implementation, it further includes a control module communicatively connected to the pressure sensors and the heating mechanism. After obtaining the type information of the paper box, the control module controls the temperature of the first airbag 33 and the pressure exerted by the pressing mechanism 3 on the paper box.

[0038] In a possible implementation, after the control module obtains the type information of the paper box, 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 airbag 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 airbag 33.

[0039] The control module has a built-in database that stores the pressures that various paper box materials can withstand during box gluing and the temperatures required for various glues to cure. During box gluing, the control module first obtains the material of the paper box and the glue material, and thus obtains the pressure that the paper box can withstand and the temperature required for glue curing from the database, and uses this pressure and temperature as the target pressure and target temperature. During the box gluing 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 airbag 33, thereby increasing the pressure exerted on the paper box by the pressing mechanism 3. If the pressure information is greater than the target pressure, it decreases the pressure of the first airbag 33, thereby decreasing the pressure exerted on the paper box by the pressing mechanism 3. If the pressure information is equal to the target pressure, it controls the first airbag 33 to maintain the current pressure. At the same time, the control module sends the target temperature to the heating mechanism. The heating mechanism has a built-in microprocessor and a temperature sensor. The temperature sensor monitors the temperature of the air flow supplied to the inside of the first airbag 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 to increase the air flow temperature. If the temperature information is higher than the target temperature, it controls the heating mechanism to decrease the power or stop working to reduce the air flow temperature. If the temperature information is equal to the target temperature, it controls the heating mechanism to maintain the current power to maintain the air flow temperature.

[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
