Description

Technical Field

[0001] The invention relates to the technical field of corrugated paper processing, and in particular to a moisture-proof corrugated paper continuous creasing device and method. Background Art

[0002] Moisture-proof corrugated paper is a material that has been specially treated or structurally designed to improve its moisture-proof properties. It is widely used in the packaging industry, especially in scenarios where moisture-sensitive items need to be protected.

[0003] The production of corrugated paper requires the use of a continuous corrugated paper pressing device, whose main function is to fold, press and seal the corrugated cardboard through the pressing process to form a complete finished carton.

[0004] For example, the Chinese patent with the announcement number CN110625993B discloses a high-strength, fold-resistant, press-line forming device for corrugated cardboard, comprising an equipment frame, a loading conveyor belt movably mounted on the equipment frame, a discharging conveyor belt movably mounted at the end of the equipment frame away from the loading conveyor belt, a corrugated bottom plate fixedly mounted between the discharging conveyor belt and the loading conveyor belt, a drive box fixedly mounted on the outside of the end of the equipment frame close to the loading conveyor belt, a maintenance door movably mounted on the outside of the drive box, a drive motor fixedly mounted in the drive box, an output steering wheel movably mounted at one end of the drive motor, and a positioning fixing frame movably mounted at the end of the output steering wheel away from the drive motor. The high-strength, fold-resistant, press-line forming device for corrugated cardboard is easy to operate and can be easily operated, which increases the speed of the entire processing work and improves work efficiency. It can also reduce safety hazards and help companies reduce operating costs.

[0005] However, the above device still has some shortcomings in actual use:

[0006] 1. First, in the above-mentioned prior art, the corrugated paper is crimped by a forming roller. However, when the forming roller rolls and crimps the corrugated paper, the pressure on the corrugated paper is often uneven, resulting in uneven crimping of the corrugated paper. When the pressure is small, the indentation on the surface of the corrugated paper is unclear; when the pressure is large, the indentation on the surface of the corrugated paper is too deep, directly causing the paperboard to deform.

[0007] 2. Secondly, when conventional forming rollers are used to press corrugated paper, electric heating is usually used to control the temperature of the forming rollers. This not only requires continuous heating during pressing, resulting in high energy consumption, but also causes uneven temperature on the surface of the forming rollers. When pressing corrugated paper in areas with higher surface temperatures, it is not only easy to cause local carbonization of the paperboard, but also damage its waterproof effect.

[0008] 3. Subsequently, the wire pressing device of the existing device is single, only having a forming roller of a single size, resulting in a fixed wire pressing size of the device that cannot be adjusted. Moreover, the operation of replacing the forming roller is not only complex, but also likely to damage some heating wire harnesses on the surface of the forming roller during the replacement process, further leading to poor applicability of the device.

[0009] Therefore, under the viewpoints stated above, there is still room for improvement in the existing device. Summary of the Invention

[0010] In order to solve the above problems, the present invention provides a moisture-proof corrugated paper continuous wire pressing device and method, adopting the following technical solutions:

[0011] In the first aspect, the present application provides a moisture-proof corrugated paper continuous wire pressing device, including a stationary workbench.

A control frame is provided on the two moving frames. Two symmetric telescopic columns are installed on the inner side of the control frame. On the opposite sides of the two telescopic columns, C-shaped cylinders are respectively installed. The two C-shaped cylinders are movably abutted against the active wire pressing wheel and the passive wire pressing wheel. Annular grooves for inserting and limiting the C-shaped cylinders are provided on both sides of the active wire pressing wheel and the passive wire pressing wheel.

[0017] A guide post and a guide screw rod are respectively installed on the control frame. Both the guide post and the guide screw rod penetrate through the control frame and are connected to the outer wall of the U-shaped cylinder, and the guide screw rod is screwed with the control frame.

[0018] Preferably, a plurality of fixing plates are installed on one side of the two U-shaped cylinders facing each other. A plurality of balls are installed on the fixing plates at equal intervals. One side of the fixing plate close to the balls is inserted into the annular groove.

[0019] Preferably, the heat compensation type double-chamber component includes an isolation plate. The active pressing wheel is of a hollow structure, and an isolation plate that divides the inner cavity of the active pressing wheel into two mutually isolated chambers is integrally installed in the inner cavity of the active pressing wheel. The chamber located on the outer side is a sealed cavity of a ring structure, and the chamber located on the inner side is a movable cavity. High thermal conductivity metal powder is installed in the annular sealed cavity, and the heat dissipated by the high thermal conductivity metal powder is transferred to the active pressing wheel, facilitating the active pressing wheel to thermally press the corrugated paper.

[0020] Preferably, a plurality of electromagnetic induction coils are further arranged in the sealed cavity of the active pressing wheel. A first electrode sheet is installed and connected to the electromagnetic induction coils through a wire. The first electrode sheet is attached to the outer wall of the active pressing wheel. A first annular electrode sheet is attached to the side wall of the active pressing wheel, making it in movable contact with the first electrode sheet, and ensuring the on and off of the electromagnetic induction coils during the rotation of the active pressing wheel.

[0021] Preferably, a limiting frame distributed in a rice-shaped manner is installed in the movable cavity of the active pressing wheel. An electromagnet that generates magnetism when powered on is installed in the cavity formed by the limiting frame. The electromagnet is connected to a second electrode sheet through a wire. The second electrode sheet is attached to the outer wall of the active pressing wheel, and the first electrode sheet and the second electrode sheet are distributed in a staggered manner.

[0024] Second, the present application provides a method for continuously pressing moisture-proof corrugated paper, as follows:

[0025] S1. Pretreatment: First, cut the corrugated paper to make the size of the corrugated paper consistent;

[0026] S2. Continuous Conveying: The prepared corrugated paper is placed on the conveyor belt of the continuous conveying mechanism and conveyed at a constant speed. After the corrugated paper moves to the designated processing area, the lifting mechanism lifts it so that the corrugated paper is in a suspended state.

[0027] S3. Pressing Operation: Then, the active pressing wheel and the passive pressing wheel in the pressing mechanism approach each other, and the pressing mechanism performs a pressing operation on the corrugated paper.

[0028] S4. Circular Operation: When the corrugated paper completes the pressing operation, the lifting mechanism places the corrugated paper that has completed pressing back on the conveyor belt again and conveys it to the unified collection place. Other corrugated papers to be pressed on the conveyor belt move to the designated processing area for processing, thereby realizing the continuous pressing operation of the corrugated paper.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] First, in the present invention, an annular sealed cavity is opened inside the active pressing wheel. The sealed cavity is filled with high - thermal - conductivity metal powder, and eddy - current heating is achieved through the electromagnetic induction coil at the end. It is heated to the specified temperature in a very short time, greatly ensuring the stability of the hot pressing of the active pressing wheel. Moreover, electromagnetic induction local heating is more energy - efficient than traditional electric heating tubes, reducing energy consumption.

[0031] Second, the dynamic anti - sticking mechanism of the present invention impacts the corrugated paper by jetting air, avoiding the corrugated paper from sticking to the passive pressing wheel and the active pressing wheel when the active pressing wheel and the passive pressing wheel perform hot pressing on the corrugated paper. Anti - sticking is achieved through mechanical structure design, while avoiding the chemical coatings sprayed on the surfaces of the active pressing wheel and the passive pressing wheel in traditional technologies to prevent sticking, and further avoiding the decomposition of the sprayed chemical coatings at high temperatures for a long time and polluting the corrugated paper.

[0032] Third, the active pressing wheel and the passive pressing wheel of the present invention can limit the active pressing wheel and the passive pressing wheel through the guiding screw rod to control the two U - shaped cylinders. The cooperation between the U - shaped cylinder and the guiding screw rod can achieve the rapid switching of the active pressing wheel and the passive pressing wheel, realizing the rapid replacement of the active pressing wheel and the passive pressing wheel with different thicknesses, greatly improving the applicability of the device.

[0046] The following is a further detailed description of the present application in conjunction with Figures 1-10 the accompanying drawings.

[0047] The embodiments of the present application disclose a moisture-proof corrugated paper continuous creasing device and method. The moisture-proof corrugated paper continuous creasing device is primarily used in the creasing process of corrugated paper A. However, in the prior art, corrugated paper A is creasing by a forming roller, but the forming roller can easily cause unclear indentations and deformation of the cardboard. Secondly, the existing traditional heating creasing method has high energy consumption, and uneven temperature can easily cause local carbonization of the cardboard. Furthermore, the existing device has a single creasing device and cannot replace the forming roller for creasing, resulting in poor applicability of the device.

[0048] Reference Figure 1 and Figure 2 , which is a schematic structural diagram of the moisture-proof corrugated paper continuous pressing device in the present application, which includes a stationary workbench 1.

[0049] The stationary workbench 1 serves as the base support structure. Four sets of adjustable feet (not shown) are installed at the bottom of the workbench 1. Adjustment bolts allow for height adjustment, ensuring the stability of the equipment in varying floor environments. A continuous conveying mechanism 2 and a press mechanism 3 are located on either side of the workbench 1 along its length (i.e., the direction in which corrugated paper A is conveyed), respectively, to accommodate the processing needs of corrugated paper A of varying specifications.

[0050] Reference Figure 3 and Figure 4 As shown, the continuous conveying mechanism 2 is used to continuously convey corrugated paper A and perform static elimination operations on the corrugated paper A. The continuous conveying mechanism 2 includes two sets of symmetrically distributed conveyor belts 20. The conveyor belts 20 are provided with V-shaped guide grooves 21. A number of copper-tungsten alloy discharge needles 23 are distributed on the side walls of the V-shaped guide grooves 21 to eliminate static adsorption of cardboard through high-frequency pulses.

[0051] The two symmetrical conveyor belts 20 of the continuous conveying mechanism 2 are made of food-grade rubber. The V-shaped guide grooves 21 not only align the edges of the corrugated paper A but also assist in attracting the paper A through the airflow channels within the grooves, preventing it from shifting during conveyance. Furthermore, the copper-tungsten alloy discharge needles 23 also ensure stable conveyance on the conveyor belts 20.

[0052] Copper-tungsten alloy discharge needles 23 are evenly distributed along V-shaped guide grooves 21 on the upper surface of conveyor belt 20. These needles 23 contact copper-based plates 24 via conductive plates 25. These plates 24 are secured to both sides of the workbench 1 via insulating brackets. A high-frequency pulse power supply (not shown) creates a corona discharge between the copper-tungsten alloy discharge needles 23 and the surface of the corrugated paper A, rapidly neutralizing static electricity and eliminating adsorption.

[0053] See Figure 5As shown, the crimping mechanism 3 realizes the crimping operation of the corrugated paper A at different angles. The crimping mechanism 3 includes an active crimping wheel 30 for pressing the upper end surface of the corrugated paper A and a passive crimping wheel 31 for supporting the bottom of the corrugated paper A. The active crimping wheel 30 and the passive crimping wheel 31 are also provided with a heat-compensated double-cavity component 4 for heating them.

[0054] The present invention opens an annular closed cavity 41 inside the active wire crimping wheel 30, and the closed cavity 41 is filled with high thermal conductivity metal powder 43. Eddy current heating is achieved through the electromagnetic induction coil 300 at the end, and the temperature is raised to the specified temperature in a very short time, which greatly ensures the stability of the hot pressing of the active wire crimping wheel 30. In addition, the electromagnetic induction local heating is more energy-efficient than the traditional electric heating tube, reducing energy consumption.

[0055] Replay Figure 3 and Figure 4 As shown, specifically, the continuous conveying mechanism 2 also includes a power-carrying plate 24, and a conductive plate 25 is installed on one side of the copper-tungsten alloy discharge needle 23. The conductive plate 25 is movably pressed against the power-carrying plate 24. The power-carrying plate 24 is mounted on the workbench 1, and a power-carrying device is provided on the power-carrying plate 24 through a wire.

[0056] It should be noted that the powered device is an existing high-frequency pulse power supply, which is mainly composed of external mains power.

[0057] In the initial state, the energized sheet 24 and the conductive sheet 25 are in a separated state. When the conveyor belt 20 controls the corrugated paper A to move to the designated processing area, the conductive sheet 25 and the energized sheet 24 will come into contact. At this time, the energized device controls the copper-tungsten alloy discharge needle 23 to discharge through the conductive sheet 25 and the energized sheet 24, so that the copper-tungsten alloy discharge needle 23 and the surface of the corrugated paper A form corona discharge, quickly neutralizing the static electricity on the surface of the corrugated paper A and eliminating the adsorption phenomenon.

[0058] Reference Figure 5 As shown, specifically, the continuous conveying mechanism 2 is also provided with a lifting mechanism 26, which includes a lifting electric push rod 260, the output end of the lifting electric push rod 260 is facing upward and is installed with a lifting frame 261, and the lifting frame 261 is installed with lifting plates 262 distributed in a rectangular shape, and the lifting plates 262 are installed with a lifting motor 263. A number of reversing wheels 264 are arranged at equal intervals on the lifting plates 262, and the lifting motor 263 is connected to the reversing wheel 264, and the direction of the corrugated paper A is controlled by the reversing wheel 264.

[0059] In the middle processing area of the conveyor belt 20, a lifting mechanism 26 is provided. This mechanism includes two groups of symmetrically distributed lifting electric push rods 260, which are driven by a servo motor and have high positioning accuracy. The output end of the lifting electric push rod 260 is connected to a lifting frame 261, and four lifting disks 262 distributed in a rectangle are installed at the bottom of the lifting frame 261, and a lifting motor 263 is embedded inside. A reversing wheel 264 is arranged on the surface of the lifting disk 262, and the wheel body is made of polyurethane material with a relatively high surface roughness. When the corrugated paper A is conveyed to the designated position, the lifting electric push rod 260 rises, and the reversing wheel 264 contacts the bottom surface of the corrugated paper A, and the corrugated paper A is rotated by ±90° through the forward and reverse rotation of the motor to meet the multi-angle pressing line requirements.

[0060] Refer to Figure 6 As shown, specifically, on the inner and outer sides of the workbench 1, there are moving frames 44 for controlling the multi-directional movement of the active pressing wheel 30 and the passive pressing wheel 31. On the two moving frames 44, there is a control frame 45. On the inner side of the control frame 45, two symmetric telescopic columns 46 are installed. On the opposite sides of the two telescopic columns 46, U-shaped cylinders 47 are respectively installed. The two U-shaped cylinders 47 are movably abutted against the active pressing wheel 30 and the passive pressing wheel 31, and annular grooves 48 for the U-shaped cylinders 47 to be inserted and limited are opened on both sides of the active pressing wheel 30 and the passive pressing wheel 31.

[0061] A guide column �0 and a guide screw 451 are respectively installed on the control frame 45. The guide column 450 and the guide screw 451 both pass through the control frame 45 and are connected to the outer wall of the U-shaped cylinder 47, and the guide screw 451 is screwed with the control frame 45.

[0062] The core of the pressing line mechanism 3 is the active pressing wheel 30 and the passive pressing wheel 31. Both are made of die steel and have a high surface hardness. The active pressing wheel 30 and the passive pressing wheel 31 are adjusted in multiple directions through the moving frame ´4. The moving frame 44 is supported by linear sliding rails on the inner and outer sides of the workbench 1 and can move in the length (X-axis), width (Y-axis), and height (Z-axis) directions. The moving accuracy is controlled by a servo motor. Therefore, the mutual approach and pressing line operation of the active pressing wheel 30 and the passive pressing wheel 31 are realized through the two moving frames 44, greatly improving the flexibility of the device for pressing lines.

[0063] On the opposite sides of the two U-shaped cylinders 47, a number of fixing plates 452 are installed. A number of balls 453 are equidistantly installed on the fixing plates 452, and one side of the fixing plate 452 close to the balls 453 is inserted into the annular groove 48.

[0064] When it is necessary to replace the active pressure roller 30 or the passive pressure roller 31, loosen the guiding screw 451, and control the U-shaped cylinder 47 to move away from the active pressure roller 30 or the passive pressure roller 31 through the telescopic column 46, then the old roller can be quickly disassembled and a new roller can be installed, and the single replacement time can be controlled within one minute. And when a new wheel needs to be replaced, reverse-rotate the guiding screw 451 to make the fixing plate 452 on the U-shaped cylinder 47 insert into the annular groove 48 of the active pressure roller 30 or the passive pressure roller 31, and the ball 453 on the fixing plate 452 abuts against the active pressure roller 30 or the passive pressure roller 31, and the friction between the two is reduced through the ball 453. The fixing plate 452 can improve the connection stability between the U-shaped cylinder 47 and the active pressure roller 30 or the passive pressure roller 31, but at the same time can ensure the rotation operation of the active pressure roller 30 or the passive pressure roller 31 when moving.

[0065] Refer to Figure 7 and [[ID=ó]] Figure 8 As shown, specifically, the heat compensation type double-chamber component 4 includes an isolation plate 40. The active pressure roller 30 is of a hollow structure, and an isolation plate 40 that divides the inner cavity of the active pressure roller 30 into two mutually isolated chambers is integrally installed in the inner cavity of the active pressure roller 30. The chamber located on the outer side is a closed cavity 41 with an annular structure, and the chamber located on the inner side is a movable cavity 42. A high thermal conductivity metal powder 43 is installed in the annular closed cavity 41, and the heat dissipated by the high thermal conductivity metal powder 43 is transferred to the active pressure roller 30, facilitating the active pressure roller 30 to perform hot pressing on the corrugated paper A.

[0066] The active pressure roller 30 adopts a hollow structure and is internally divided into an outer closed cavity 41 and an inner movable cavity 42 by an isolation plate 40. The closed cavity 41 has an annular structure and is filled with high thermal conductivity metal powder 43 with a certain particle size. On the outer side wall of the closed cavity 41, an electromagnetic induction coil 300 is evenly wound, and conductive connection is achieved through the first electrode piece 301 and the first annular electrode piece 302. When an alternating current with a certain frequency is passed through the coil, an eddy current effect is generated in the metal powder. According to Joule's law, the eddy current loss is converted into heat energy, so that the surface temperature of the active pressure roller 30 can rise to the specified temperature within a short time (monitored in real time by a temperature controller). This heating method has higher efficiency and lower energy consumption compared with the traditional electric heating tube heating.

[0067] Moreover, the high thermal conductivity metal powder 43 also has a certain temperature storage effect, reducing the speed of temperature cooling. At the same time, using the high thermal conductivity metal powder 43 as a medium can avoid the situation that the active pressure roller 30 is directly heated resulting in uneven temperature distribution and uncontrollable temperature.

[0068] Refer to Figure 8As shown, a number of electromagnetic induction coils 300 are also provided in the closed cavity 41 of the active wire-pressing wheel 30. The electromagnetic induction coils 300 are connected to the No. 1 electrode sheet 301 through a wire. The No. 1 electrode sheet 301 is attached to the outer wall of the active wire-pressing wheel 30. The No. 1 annular electrode sheet 302 is attached to the side wall of the active wire-pressing wheel 30, so that it is in active contact with the No. 1 electrode sheet 301, and ensures that the electromagnetic induction coil 300 is powered on and off during the rotation of the active wire-pressing wheel 30.

[0069] It should be noted that the No. 1 annular electrode sheet 302 and the No. 2 annular electrode sheet 306 are both connected to external powered equipment, and the No. 1 electrode sheet 301 and the No. 2 electrode sheet 305 are against the No. 1 annular electrode sheet 302 and the No. 2 annular electrode sheet 306. The purpose is to ensure that when the active wire-pressing wheel 30 rotates, it is also convenient for the electromagnetic induction coil 300 inside it to be powered on and off.

[0070] Furthermore, it is also possible to facilitate replacement of active crimping wheels 30 of different thicknesses and sizes.

[0071] Look again Figure 7 and Figure 8 As shown, a limit frame 303 distributed in a rice shape is installed in the movable cavity 42 of the active wire-pressing wheel 30, and an electromagnet 304 that generates magnetism when powered is installed in the cavity formed by the limit frame 303. The electromagnet 304 is connected to the second electrode sheet 305 through a wire. The second electrode sheet 305 is attached to the outer wall of the active wire-pressing wheel 30, and the No. 1 electrode sheet 301 and the No. 2 electrode sheet 305 are staggered. The No. 2 annular electrode sheet 306 is attached to the side wall of the active wire-pressing wheel 30, so that it is in active contact with the No. 2 electrode sheet 305.

[0072] A rice-shaped limiter 303 is located within the active cavity 42, with an electromagnet 304 mounted at its center. Power is supplied to the electromagnet 304 via a second electrode plate 305 and a second annular electrode plate 306. The magnetic field generated by the electromagnet 304 helps regulate the internal heat flow distribution of the active crimping wheel 30. This, combined with the thermal conductivity of the sealed cavity 41, minimizes surface temperature uniformity on the active crimping wheel 30.

[0073] Reference Figure 9 As shown, the active crimping wheel 30 is also provided with a dynamic anti-sticking mechanism 5, which includes annular grooves 50 with equal intervals on the surface of the active crimping wheel 30, and the annular grooves 50 are also provided with an inlet and outlet 51 that is connected to the outside and has integrated air inlet and outlet.

[0074] An air outlet frame 52 is movably abutted against the top of the active crimping wheel 30 . An end of the air outlet frame 52 away from the active crimping wheel 30 is connected to an air pump 53 through a pipeline. The air pump 53 is arranged on the movable frame 44 .

[0075] The active crimping wheel 30 has an annular groove 50 on its surface, and an inlet and outlet 51 is provided at the bottom of each groove to connect with the internal air passage (such as Figure 9 As the active creasing wheel 30 rotates, the air pump 53 periodically injects compressed air into the groove, forming a pulsed jet through the inlet and outlet 51, forming an air film on the contact surface between the active creasing wheel 30 and the corrugated paper A, effectively preventing the corrugated paper A from sticking.

[0076] Compared with traditional chemical coating anti-sticking technology, this mechanism does not need to use any chemical coating, avoiding the decomposition of the coating at high temperature to produce toxic substances that pollute the corrugated paper A.

[0077] This application addresses the issues of low heating efficiency, sticking, and poor equipment applicability that exist in traditional corrugated paper A press lines through the collaborative design of electromagnetic induction heating technology, a pulsed jet anti-sticking mechanism, and a rapid mold change mechanism. This technical solution not only improves production efficiency and product quality but also meets the environmental requirements of green manufacturing, making it widely applicable to automated production lines for corrugated paper A production.

[0078] Reference Figure 10 As shown, the continuous pressing method of moisture-proof corrugated paper is as follows:

[0079] S1. Pretreatment: First, use a high-precision cross-cutting machine to cut the base paper. The cut corrugated paper A needs to be left to stand in a constant temperature and humidity environment for 2 hours to eliminate internal stress.

[0080] S2. Continuous conveying: The prepared corrugated paper A is placed on the conveyor belt 20 of the continuous conveying mechanism 2 and conveyed at a uniform speed. After the corrugated paper A moves to the designated processing area, the lifting mechanism 26 lifts it so that the corrugated paper A is in a suspended state.

[0081] The conveyor belt 20 starts to rotate at a uniform speed, and the prepared corrugated paper A is placed on the conveyor belt 20 of the continuous conveying mechanism 2 and conveyed at a uniform speed. When the front end of the corrugated paper A reaches the designated processing area, the lifting electric push rod 260 rises, and the reversing wheel 264 of the lifting plate 262 contacts the bottom surface of the corrugated paper A, so that the corrugated paper A is in a suspended state.

[0082] S3. Pressing operation: When the corrugated paper A enters the pressing area, the moving frame 44 drives the active pressing wheel 30 and the passive pressing wheel 31 to move toward each other until they contact the corrugated paper A. The electromagnetic induction coil 300 is simultaneously energized and heated. When the surface temperature of the active pressing wheel 30 reaches a specified temperature, the pressing operation begins along the surface of the corrugated paper.

[0083] S4, Circular Operation: The corrugated paper A that has been crimped is lowered by the lifting mechanism 26 to the conveyor belt 20. The conveyor belt 20 then starts to control the movement of the crimped corrugated paper A and moves it to a designated location for collection. At the same time, the next sheet of corrugated paper A to be processed is delivered to the designated location. The entire cycle can achieve a continuous processing efficiency of multiple sheets of corrugated paper A per minute.
