Description

Technical Field

[0001] This invention relates to the field of paperboard processing technology, and in particular to a corrugated paper cold pressing mechanism, a cold pressing forming device, and a method of using the same. Background Technology

[0002] Cold presses are used to flatten corrugated paper, making the adhesion between the corrugated sheets stronger. Existing cold presses typically consist of an upper pressure plate and a cold pressure plate. The corrugated paper is laid on the cold pressure plate, and then the upper pressure plate is driven downwards to flatten the paper. This method of flattening the paper does not allow for adjustment of the width of the flattened corrugated paper, and the pressure of the cold pressure plate cannot be adjusted during operation. Furthermore, cold press mechanisms that use screws to drive the cold pressure plate up and down have the drawback of difficulty in keeping the cold pressure plate on the same horizontal plane. Summary of the Invention

[0003] The purpose of this invention is to provide a corrugated paper cold pressing mechanism, a cold pressing forming device and a method of using the same, so as to solve one or more technical problems existing in the prior art, or at least provide a beneficial option or create conditions.

[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows:

[0005] This invention provides a corrugated paper cold pressing mechanism, including a lower pressing seat and a lower pressing drive. The lower pressing seat is provided with multiple sets of cold pressing components. Each cold pressing component includes a horizontally arranged cold pressing plate and a width adjustment drive unit. The cold pressing plate and the lower pressing seat are connected by a swing arm mechanism. The width adjustment drive unit is used to drive the swing arm mechanism to swing, thereby causing the cold pressing plate to move up and down. Among the multiple cold pressing plates arranged in parallel, the sides of adjacent cold pressing plates form inclined slits that are inclined left and right. A bladder cylinder is provided between the lower pressing seat and the cold pressing plate. The lower pressing drive is used to drive the lower pressing seat to move up and down.

[0006] The beneficial effects of this invention are:

[0007] During operation, the downward pressure drive unit drives the lower pressure seat to move downward. Then, by adjusting the bladder cylinder and the width adjustment drive unit, the pressure of the cold press plate on the corrugated cardboard is further adjusted, so that the corrugated cardboard is subjected to uniform force while ensuring the force-bearing area of ​​the corrugated cardboard. The bladder cylinder can withstand radial and axial loads, satisfying the characteristics of the cold press plate's tilting and vertical movement. The swing arm mechanism ensures that the cold press plate remains in a horizontal state during the adjustment process, which is beneficial for flattening the corrugated cardboard. The inclined slit is set so that the corrugated cardboard will not have bulges when passing through the corrugated paper cold pressing mechanism. In addition, the width adjustment drive unit can drive the cold press plate to swing upward, so as to lift the cold press plate and adjust the pressing width of the cold press plate.

[0008] As a further improvement to the above technical solution, the rocker arm mechanism includes two sets of rocker arm components and an adjusting rod arranged at a front-to-back interval. Each rocker arm component includes at least two rocker arm bodies arranged at a left-to-right interval. The two ends of each rocker arm body are respectively hinged to the upper surfaces of the lower pressure seat and the cold pressing plate. The lower end of the adjusting rod is fixedly connected to the rocker arm body, and the upper end of the adjusting rod is drively connected to the output end of the wide-range adjustment drive unit. The bladder cylinder is disposed between the two sets of rocker arm components, and the upper end of the rocker arm body is located above and behind the lower end of the rocker arm body.

[0009] The rocker arm mechanism ensures that the cold press plate remains on the same horizontal plane during the up-and-down adjustment process.

[0010] As a further improvement to the above technical solution, the multiple sets of cold pressing components include a first cold pressing component, a second cold pressing component, and a third cold pressing component. The first cold pressing component includes side pressure plates that are right-angled trapezoids located on both sides. The second cold pressing component includes a fixed pressure plate that is an isosceles trapezoid located in the middle. The third cold pressing component includes an adjusting pressure plate that is arranged in a parallelogram shape. The adjusting pressure plates located on both sides of the fixed pressure plate are symmetrically arranged with the central axis of the fixed pressure plate as the axis of symmetry.

[0011] An inclination adjustment mechanism and a translation adjustment mechanism are provided between the lower pressure seat and the cold pressing assembly. The inclination adjustment mechanism is used to adjust the third cold pressing assembly to move back and forth along the inclination direction of the inclination seam, and the translation adjustment mechanism is used to drive the first cold pressing assembly to move closer to the second cold pressing assembly.

[0012] When the width of the corrugated cardboard is smaller than the width of the cold press plate, the edges of the corrugated cardboard bear the pressure of the entire cold press plate. This excessive pressure on the edges can easily cause buckling, collapse, thinning of the edges, and reduced strength, ultimately leading to quality problems. To prevent bulging, the edges of the cold press plates are angled, and the two sides of the corrugated cardboard are parallel. Therefore, even when the side cold press plate is lifted, the two sides of the corrugated cardboard still experience excessive pressure.

[0013] Therefore, a first cold pressing assembly, a second cold pressing assembly, and a third cold pressing assembly are respectively set up. The straight edge of the side pressing plate of the first cold pressing assembly is parallel to the edge of the corrugated cardboard, so that the side pressing plate is always in working state. Therefore, the fixed pressing plate of the third cold pressing assembly is removed. After the fixed pressing plate is removed, the side pressing plate and the fixed pressing plate are brought together so that the cold pressing range is roughly rectangular, so that the edge of the corrugated cardboard will not have problems such as excessive local stress or thinning.

[0014] Furthermore, the symmetrical arrangement of the cold pressing plates can improve the stability of the entire corrugated paper cold pressing mechanism during the adjustment process.

[0015] As a further improvement to the above technical solution, the tilt adjustment mechanism includes two upper guide rails tilted on the lower pressure seat and a tilt moving frame disposed on the third cold pressing component. The tilt moving frame is slidably fixed on the upper guide rails and is provided with a first translation slide rail. The translation adjustment mechanism includes a second translation slide rail disposed on the lower pressure seat and the first cold pressing component is slidably disposed on the second translation slide rail.

[0016] After the third cold pressing component moves away from between the two cold pressing components, the first cold pressing component moves from the second translation slide rail to the first translation slide rail, thereby moving closer to the second cold pressing component.

[0017] The upper guide rail, the first translation slide rail, and the second translation slide rail can all improve the stability of the adjustment. In particular, the first translation slide rail is set on the tilting moving frame so that after the third cold pressing component moves away from between the two cold pressing components, it does not interfere with the first cold pressing component moving towards the second cold pressing component to form a new roughly rectangular paper pressing range. This achieves the purpose of retaining the operation of the first cold pressing component while removing the third cold pressing component.

[0018] As a further improvement to the above technical solution, the tilt adjustment mechanism includes a tilt drive unit for driving the third cold pressing component to move, and the translation adjustment mechanism includes a translation drive unit for driving the first cold pressing component to move.

[0019] The movement of the third and first cold-pressing components is automatically adjusted, improving the level of automation and making adjustment more convenient.

[0020] As a further improvement to the above technical solution, the adjusting plate has the same width in the left and right directions, which facilitates control over the adjustment width.

[0021] As a further improvement to the above technical solution, parallelogram-shaped adjustment plates are respectively engaged at the edges between the adjusting pressure plate and the side pressure plate. When the width variation of the corrugated cardboard is small, one or two adjustment plates can be inserted, and then the translation adjustment mechanism drives the side pressure plate to move closer to the adjusting pressure plate, thus expanding the adjustment range. It can also be combined with a tilting adjustment mechanism to achieve more adjustment methods to accommodate corrugated cardboard of various widths.

[0022] As a further improvement to the above technical solution, the front and rear sides of the cold press plate are respectively curved upwards, which can ensure that the corrugated cardboard can pass smoothly under the cold press plate during processing, so as to avoid the cold press plate damaging the corrugated cardboard.

[0023] The present invention also provides a cold pressing forming apparatus, including a corrugated paper cold pressing mechanism as described in any one of the above claims and a corrugated paper conveying mechanism disposed below the corrugated paper cold pressing mechanism.

[0024] The corrugated paper cold pressing mechanism acts above the corrugated paper conveying mechanism, which transports corrugated paperboard. The corrugated paperboard is then cold-pressed by the corrugated paperboard cold pressing mechanism. Since the width of the corrugated paper cold pressing mechanism can be adjusted, it can be adapted to corrugated paperboards of different widths.

[0025] The present invention also provides a method of using a cold pressing forming apparatus, which is applied to a cold pressing forming apparatus, comprising:

[0026] The downward drive component drives the downward pressure seat to move downward;

[0027] Adjust the width adjustment drive unit to control the interval between the cold press plate and the conveying surface of the corrugated paper conveying mechanism;

[0028] Adjusting the air pressure of the bladder cylinder thereby adjusts the pressure of the corrugated cardboard on the conveying surface of the corrugated paper conveying mechanism applied by the cold press plate.

[0029] First, the cardboard passage interval is roughly adjusted by the width adjustment drive unit. Then, the pressure of the cold press plate on the corrugated cardboard is adjusted by the bladder cylinder to control the pressure of the cold press plate on the corrugated cardboard and ensure that the cold press plate has a sufficient contact area.

[0030] As a further improvement to the above technical solution, the corrugated paper conveying mechanism transports the corrugated paperboard from front to back relative to the cold press plate. When the corrugated paperboard is conveyed, it acts on the cold press plate, providing a backward force to the cold press plate. This force causes the cold press plate to move downward, thereby allowing the cold press plate to act more effectively on the corrugated paperboard. Attached Figure Description

[0041] Cold presses are used to flatten corrugated paper, making the adhesion between the corrugated sheets stronger. Existing cold presses generally consist of an upper pressure plate and a cold pressure plate. The corrugated paper is laid on the cold pressure plate, and then the upper pressure plate is driven downwards to flatten the corrugated paper. This method of flattening cannot adjust the width of the flattened corrugated paper, and the pressure of the cold pressure plate cannot be adjusted during operation. Furthermore, cold press mechanisms that use screws to drive the cold pressure plate up and down have the drawback of difficulty in keeping the cold pressure plate on the same horizontal plane. Therefore, referring to... Figures 1 to 5 The present invention provides a corrugated paper cold pressing mechanism, a cold pressing forming device, and a method of using the same, as illustrated in the following embodiments:

[0042] In some embodiments, a corrugated paper cold pressing mechanism includes a lower pressing base 100 and a lower pressing drive 500. The lower pressing base 100 is used to install a plurality of cold pressing plates 210, so that the plurality of cold pressing plates 210 move up and down simultaneously. The lower pressing drive 500 is used to drive the lower pressing base 100 to move up and down, so that the cold pressing plates 210 move downward to press the corrugated paperboard for cold pressing, or drive the cold pressing plates 210 to move upward to adjust the interval between the cold pressing plates 210 and the lower pressing surface, and adjust the pressure of the cold pressing plates 210 on the corrugated paperboard to make the cold pressing effect better.

[0043] The pressure drive unit 500 includes a pressure drive motor, which is connected to the pressure base 100 and is mounted on the frame. In some other embodiments, a cylinder, an electric push rod, or a motor lead screw drive is used as the drive unit.

[0044] The lower pressure seat 100 is provided with multiple sets of cold pressing components spaced apart from left to right. Each cold pressing component includes a horizontally arranged cold pressing plate 210 and a width adjustment drive unit 220. The cold pressing plate 210 is connected to the lower pressure seat 100 through a swing arm mechanism 230. The width adjustment drive unit 220 is used to drive the swing arm mechanism 230 to swing, thereby causing the cold pressing plate 210 to move up and down. Among the multiple cold pressing plates 210 arranged in parallel, the sides of adjacent cold pressing plates 210 form inclined slots 211 that are inclined from left to right. A bladder cylinder 240 is provided between the lower pressure seat 100 and the cold pressing plate 210.

[0045] The bellows cylinder 240 forms a compressed air chamber, utilizing the compressibility of air to achieve an elastic effect. It is a non-metallic spring with the characteristics of a spring, while also possessing the advantages of a superior metallic spring: it can simultaneously withstand axial and radial loads, and by adjusting the internal pressure, different load-bearing capacities can be adjusted to adapt to various load requirements. The bellows cylinder 240 also has good vibration damping and sound insulation properties, and is easy to replace.

[0046] During operation, the downward pressure drive 500 drives the downward pressure seat 100 to move downward. Then, by adjusting the bellows cylinder 240 and the width adjustment drive unit 220, the pressure of the cold press plate 210 on the corrugated cardboard is further adjusted, so that the corrugated cardboard is subjected to uniform force while ensuring the force-bearing area of ​​the corrugated cardboard. The bellows cylinder 240 can withstand radial and axial loads, satisfying the characteristic of the cold press plate 210 to move up and down at an angle. The swing arm mechanism 230 ensures that the cold press plate 210 is always in a horizontal state during the adjustment process, which is beneficial for flattening the corrugated cardboard. The inclined slit 211 is set so that the corrugated cardboard will not have bulges when passing through the corrugated paper cold pressing mechanism. The width adjustment drive unit 220 can drive the cold press plate 210 to swing upward, so that the cold press plate 210 can be lifted and the pressing width of the cold press plate 210 can be adjusted.

[0047] Specifically, the rocker arm mechanism 230 includes two sets of rocker arm components and an adjusting rod 232 arranged at a front-to-back interval. Each rocker arm component includes two rocker arm bodies 231 arranged left-to-right. The two ends of each rocker arm body 231 are hinged to the upper surfaces of the lower pressure seat 100 and the cold-pressing plate 210, respectively. The lower end of the adjusting rod 232 is fixedly connected to the rocker arm body 231, and the upper end of the adjusting rod 232 is drively connected to the output end of the wide-range adjustment drive unit 220. The bladder cylinder 240 is disposed between the two sets of rocker arm components, with the upper end of each rocker arm body 231 located above and behind its lower end. In this embodiment, the wide-range adjustment drive unit 220 is a wide-range adjustment cylinder disposed above the lower pressure seat 100.

[0048] The rocker arm mechanism 230 ensures that the cold press plate 210 remains on the same horizontal plane during the up-and-down adjustment process.

[0049] Reference Figures 3 to 5 The multiple sets of cold pressing components include two sets of first cold pressing components 200, one set of second cold pressing components 300, and six sets of third cold pressing components 400. The first cold pressing component 200 includes side pressure plates 201 that are right-angled trapezoids located on both sides. The second cold pressing component 300 includes a fixed pressure plate 301 that is isosceles trapezoidal located in the middle. The third cold pressing component 400 includes an adjusting pressure plate 401 that is arranged in a parallelogram shape. The adjusting pressure plates 401 located on both sides of the fixed pressure plate 301 are symmetrically arranged with the central axis of the fixed pressure plate 301 as the axis of symmetry.

[0050] An inclination adjustment mechanism and a translation adjustment mechanism are provided between the lower pressure seat 100 and the cold pressing assembly. The inclination adjustment mechanism is used to adjust the third cold pressing assembly 400 to move back and forth along the inclination direction of the inclination seam 211, and the translation adjustment mechanism is used to drive the first cold pressing assembly 200 to move closer to the second cold pressing assembly 300.

[0051] It should be noted that the cold pressing assembly still includes the wide-range adjustment drive unit 220 and the swing arm mechanism 230. After the positions of each cold pressing component are moved, the cold pressing plate 210 of the cold pressing assembly can still independently rise and fall.

[0052] When the width of the corrugated cardboard is smaller than the width of the cold press plate 210, the edges of the corrugated cardboard bear the pressure of the entire cold press plate 210. This excessive pressure on the edges can easily cause buckling, collapse, thinning of the edges, and reduced strength, ultimately leading to quality problems. To prevent bulging marks on the corrugated cardboard, the edges of the cold press plates 210 are angled, and the two side edges of the corrugated cardboard are parallel. Therefore, when the side cold press plate 210 is lifted, the problem of excessive pressure on the sides of the corrugated cardboard still occurs.

[0053] Therefore, a first cold pressing assembly 200, a second cold pressing assembly 300, and a third cold pressing assembly 400 are respectively set up. The straight edge of the side pressing plate 201 of the first cold pressing assembly 200 is parallel to the edge of the corrugated cardboard, so that the side pressing plate 201 is always in working state. Therefore, the fixed pressing plate 301 of the third cold pressing assembly 400 is removed. After the fixed pressing plate 301 is removed, the side pressing plate 201 and the fixed pressing plate 301 are brought together so that the cold pressing range is roughly rectangular, so as to prevent the corrugated cardboard edge from experiencing excessive local stress and thinning.

[0054] Furthermore, the cold pressing plates 210 are symmetrically arranged, which can improve the stability of the entire corrugated paper cold pressing mechanism during the adjustment process.

[0055] In some other embodiments, the fixed pressure plate 301 in the second cold pressing assembly 300 may also be equilateral triangular. Those skilled in the art can specifically set the inclination of the inclined gap according to actual needs.

[0056] The tilt adjustment mechanism includes two upper guide rails 410 inclinedly disposed on the lower pressure seat 100 and a tilting moving frame disposed on the third cold pressing assembly 400. The tilting moving frame is slidably fixedly disposed on the upper guide rails 410. The tilting moving frame is provided with a first translation slide rail 420. There are two first translation slide rails 420, which extend left and right. The translation adjustment mechanism includes a second translation slide rail 430 disposed on the lower pressure seat 100. The second translation slide rail 430 extends front and back. The first cold pressing assembly 200 is slidably disposed on the second translation slide rail 430.

[0057] After the third cold pressing assembly 400 moves away from between the two cold pressing assemblies, the first cold pressing assembly 200 moves from the second translation slide rail 430 to the first translation slide rail 420, thereby moving closer to the second cold pressing assembly 300.

[0058] The upper guide rail 410, the first translation slide rail 420, and the second translation slide rail 430 can all improve the stability of the adjustment. In particular, the first translation slide rail 420 is set on the tilting moving frame so that after the third cold pressing component 400 moves away from between the two cold pressing components, it does not interfere with the first cold pressing component 200 moving towards the second cold pressing component 300 to form a new roughly rectangular paper pressing range. This achieves the purpose of retaining the operation of the first cold pressing component 200 while removing the third cold pressing component 400.

[0059] Furthermore, the tilt adjustment mechanism includes a tilt drive unit for driving the third cold pressing assembly 400 to move, and the translation adjustment mechanism includes a translation drive unit for driving the first cold pressing assembly 200 to move.

[0060] The movement of the third cold-pressing component 400 and the first cold-pressing component 200 is automatically adjusted, improving the degree of automation and making adjustment more convenient. All drive units in this invention are existing technologies, and the aforementioned lifting and moving movements can all be driven by cylinders, electric push rods, or motor lead screw drives. Corresponding slide rails are provided for linear motion to improve motion accuracy.

[0061] In a further improvement, the adjusting plate 401 has the same width in the left-right direction. This facilitates control over the adjustment width. In some other embodiments, the adjusting plate 401 may have different widths in the left-right direction.

[0062] In some other embodiments, parallelogram-shaped adjustment plates (not shown in the figure) are respectively engaged at the edges between the adjusting pressure plate 401 and the side pressure plate 201. The adjusting pressure plate 401 is provided with a first groove, and the edge of the adjustment plate is provided with a first protrusion, which engages with the first groove. When the width variation of the corrugated cardboard is small, one or two adjustment plates can be inserted, and then the translation adjustment mechanism drives the side pressure plate 201 to move closer to the adjusting pressure plate 401, thus increasing the adjustment range. It can also be combined with a tilt adjustment mechanism to achieve more adjustment methods to accommodate more widths of corrugated cardboard. In some other embodiments, the adjustment plates can also be engaged with the adjusting pressure plate 401 or the side pressure plate 201 by means of a snap-fit ​​or other structure.

[0063] Further improvements, refer to Figure 2 As can be seen, the front and rear sides of the cold press plate 210 are respectively curved upwards, which can ensure that the corrugated cardboard can pass smoothly under the cold press plate 210 during the processing of the corrugated cardboard, so as to prevent the cold press plate 210 from damaging the corrugated cardboard.

[0064] In some other embodiments, among the plurality of cold-pressed plates 210, two cold-pressed plates 210 on each side are right-angled trapezoids, and the remaining cold-pressed plates 210 are isosceles trapezoids placed in an alternating manner, with the hypotenuses of each trapezoid facing each other to form the inclined seam. The right-angled trapezoids on both sides ensure the regularity of the two sides of the cold-pressed plates 210, while the isosceles trapezoid in the middle ensures the inclination angle of the seam, and also facilitates interchangeability in processing, and makes the swing arm mechanism 230 subjected to balanced and uniform force during operation. However, the present invention can also use other methods to form the inclined seam, such as using triangular or parallelogram-shaped cold-pressed plates 210.

[0065] The corrugated paper cold pressing mechanism of the present invention has the following advantages: large pressing area; good pressing area effect and good flute shape maintenance, resulting in high strength of corrugated paperboard. The seam between adjacent cold pressing plates 210 is set at an inclination, resulting in flat processing of corrugated paperboard without bubbling. The horizontal angle and height of each cold pressing plate 210 can be easily adjusted. After installing the corrugated paper cold pressing mechanism of the present invention, the quality of corrugated paperboard processing is higher.

[0066] The present invention also provides an embodiment of a cold pressing forming apparatus, comprising a corrugated paper cold pressing mechanism as described in any one of the above embodiments and a corrugated paper conveying mechanism disposed below the corrugated paper cold pressing mechanism. The corrugated paper conveying mechanism is a belt conveyor mechanism. In other embodiments, the corrugated paper conveying mechanism may be a belt conveyor or a roller conveyor, or other conveying structure capable of material movement.

[0067] The corrugated paper cold pressing mechanism acts above the corrugated paper conveying mechanism, which transports corrugated paperboard. The corrugated paperboard is then cold-pressed by the corrugated paperboard cold pressing mechanism. Since the width of the corrugated paper cold pressing mechanism can be adjusted, it can be adapted to corrugated paperboards of different widths.

[0068] The present invention also provides an embodiment of a method for using a cold pressing forming apparatus, applicable to a cold pressing forming apparatus, comprising:

[0069] The downward drive component 500 drives the downward pressure seat 100 to move downward;

[0070] Adjust the width adjustment drive unit 220 to control the interval between the cold press plate 210 and the conveying surface of the corrugated paper conveying mechanism;

[0071] Adjusting the air pressure of the bladder cylinder 240 thereby adjusts the pressure of the corrugated cardboard on the conveying surface of the corrugated paper conveying mechanism by the cold press plate 210.

[0072] First, the cardboard passage interval is roughly adjusted by the wide-width adjustment drive unit 220. Then, the pressure of the cold press plate 210 on the corrugated cardboard is adjusted by the bladder cylinder 240 to control the pressure of the cold press plate 210 on the corrugated cardboard and ensure that the cold press plate 210 has sufficient contact area.

[0073] The corrugated board conveyor moves the corrugated board from front to back relative to the cold press plate 210. As the corrugated board is conveyed, it acts on the cold press plate 210, providing a backward force that causes the cold press plate 210 to move downward, thus allowing it to better apply pressure to the corrugated board. If the corrugated board is fed in the opposite direction, this downward pressure effect is not achieved.

[0074] When it is necessary to adjust the width of the pressed paper, the width adjustment drive unit 220 is controlled to drive the cold plate 210 to move upward, so that the corrugated cardboard will not be subjected to excessive pressure, which would cause uneven paper thickness. It can also prevent the cold plate 210 from directly contacting the conveying surface of the corrugated paper conveying mechanism, such as the conveyor belt surface.

[0075] To avoid bulges on the corrugated cardboard, the edges between the cold press plates 210 are set at an angle. The two sides of the corrugated cardboard are parallel to each other. Therefore, when the cold press plate 210 on the side is lifted, the two sides of the corrugated cardboard will still be subjected to large pressure. Therefore, the method of adjusting the width of the cold press plate 210 is further improved, and an angle adjustment mechanism and a translation adjustment mechanism are set.

[0076] Furthermore, the present invention also provides an embodiment of an adjustment method for a cold pressing forming apparatus. First, one or both sides of the third cold pressing assembly 400 are removed. Then, the first cold pressing assembly 200 is moved closer to the second cold pressing assembly 300. Next, the cold pressing plate 210 of the third cold pressing assembly 400 is moved upwards under the drive of the wide-range adjustment drive unit 220. This ensures that the adjusted cold pressing range is approximately rectangular, preventing problems such as excessive localized stress and thinning at the edges of the corrugated cardboard.

[0077] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
