Description

Technical Field

[0001] The utility model generally relates to the technical field of plate forming, in particular to a rolling device. Background Art

[0002] After forming, some sheet materials may experience a certain degree of rebound due to their inherent structural characteristics. For example, a flat shape formed by folding cardboard may rebound at the fold, causing bulging in some areas of the flat shape. To ensure product quality and prevent bending of the sheet material after forming, pressure holding is often required.

[0003] Existing technical solutions primarily utilize flat pressing and roller pressing. Flat pressing utilizes a flat platen to press against the sheet material, which occupies a large space and requires a long wait time. Roller pressing utilizes rollers to press against the sheet material, but these rollers can only produce uniform, strip-shaped pressure, resulting in poor pressure retention.

[0004] The contents of the background technology section are merely the technologies known to the inventors and do not necessarily represent the existing technologies in this field. Utility Model Content

[0030] The following describes embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0031] Figure 1 The structure of the roller pressing device 1 in some embodiments of the present invention is shown below. Figure 1 The roll pressing device 1 will be described.

[0032] The roller pressing device 1 in this embodiment is used to maintain the pressure of the formed sheet material. The formed sheet material includes, for example, formed sheets, such as cardboard, plastic sheets, filling sheets, etc., and forming means that the sheet material has been preliminarily processed or has been processed. The formed sheet material is, for example, a carton blank made by cutting and pasting cardboard, which is not folded into a three-dimensional shape. In the planar direction, the carton blank includes multiple pieces of cardboard stacked together, but due to the material properties of the cardboard, rebound may occur, such as rebound at the position where the cardboard is folded, causing the carton blank to bulge in the middle and unable to maintain a planar shape. In this case, it is not only not conducive to storage and transportation, but also easily causes the carton blank to bend in other positions, affecting product quality.

[0033] like Figure 1As shown, the rolling device 1 includes a bracket 11, at least one first roller 12, a matching portion 13, and an adjusting portion 14. The bracket 11 is used to support the at least one first roller 12. For example, a fixing member is provided on the bracket 11. The at least one first roller 12 is disposed on the bracket 11, and the first roller 12 is configured to rotate about an axial direction.

[0034] For example, in some embodiments, the rolling device 1 further includes a driving device 15, which includes, for example, an electric motor configured to rotate the first roller 12. For example, a bearing is provided on the bracket 11, and a rotating shaft is provided axially of the first roller 12. The rotating shaft passes through the bearing, and the driving device 15 drives the first roller 12 to rotate via a transmission chain.

[0035] In a preferred embodiment of the present invention, the rolling device 1 includes a plurality of first rollers 12. The plurality of first rollers 12 can be driven and controlled independently or synchronously. In some embodiments, some of the plurality of first rollers 12 are driven by the drive device 15, while others are driven by the pressure-bearing object 2.

[0036] The position of the matching portion 13 corresponds to the position of the first roller 12, and the pressure-bearing object 2 is located between the matching portion 13 and the first roller 12. The first roller 12 and the matching portion 13 cooperate with each other and can apply pressure to the pressure-bearing object 2. The first roller 12 is located close to the matching portion 13, and the pressure-bearing object 2 is arranged between the first roller 12 and the matching portion 13, and the spacing between the first roller 12 and the matching portion 13 is equal to or slightly smaller than the thickness of the pressure-bearing object 2. During the rotation of the first roller 12, the pressure-bearing object 2 can move under the drive of the first roller 12. In other embodiments, the matching portion 13 is configured to be movable relative to the first roller 12, and the matching portion 13 can be used to drive the pressure-bearing object 2 to move, so that the pressure applied by the first roller 12 and the matching portion 13 on the pressure-bearing object 2 covers other positions in the pressure-bearing object 2.

[0037] In some embodiments, the first roller 12 is axially arranged parallel to the mating portion 13. At different positions, the distance between the first roller 12 and the mating portion 13 is substantially equal. Without considering the adjustment portion 14, the pressure on the pressure-bearing object 2 is substantially equal.

[0038] In some embodiments, the rolling device 1 includes multiple first rollers 12, and the multiple first rollers 12 are arranged in parallel. The distances between the multiple first rollers 12 and the mating portion 13 can be set to be equal, so that the pressure-bearing object 2 is continuously subjected to pressure from the multiple first rollers 12, thereby improving the pressure-maintaining effect. In other embodiments, the distances between the multiple first rollers 12 and the mating portion 13 are set to decrease. For example, the multiple first rollers 12 rotate in the same direction, and the distances between the multiple first rollers 12 and the mating portion 13 gradually decrease in the direction of rotation of the first rollers 12, thereby increasing the pressure acting on the pressure-bearing object 2 and further improving the pressure-maintaining effect.

[0039] The adjusting portion 14 is detachably provided on the circumference of at least one first roller 12. The adjusting portion 14 can change the radial dimension of at least a portion of the first roller 12, thereby changing the distance between the adjusting portion 14 and the mating portion 13, and changing the pressure acting on the pressure-bearing object 2. For part of the pressure-bearing object 2, the pressure holding requirements at different positions are different. For example, the rebound amount of some areas of the pressure-bearing object 2 is small, and the pressure holding requirement is relatively low. The rebound amount of some areas of the pressure-bearing object 2 is large, and a greater pressure needs to be provided to improve the pressure holding effect. The radial dimension of the first roller 12 is increased by using the adjusting portion 14, and the distance between the adjusting portion 14 and the mating portion 13 is adjusted to provide greater pressure to the pressure-bearing object 2, which is conducive to improving the pressure holding effect. In addition, the adjusting portion 14 is detachably provided on the circumference of the first roller 12. According to the pressure holding requirement of the pressure-bearing object 2, the position, thickness, and range of the adjusting portion 14 on the first roller 12 can be adjusted to change the size and range of the pressure acting on the pressure-bearing object 2, and can be adjusted according to the pressure-bearing object 2.

[0040] The adjustment portion 14 in this embodiment can be adjusted according to the actual needs of the pressure-bearing object 2, thereby increasing the pressure applied to a portion of the pressure-bearing object 2 and improving the pressure-maintaining effect. In some embodiments, the rolling device 1 includes a plurality of first rollers 12, and some of the plurality of first rollers 12 are provided with adjustment portions 14. The adjustment portions 14 on the plurality of first rollers 12 can be provided at different positions. When the plurality of first rollers 12 are sequentially rolled onto the pressure-bearing object 2, the adjustment portions 14 on the plurality of first rollers 12 can apply pressure to the pressure-bearing object 2 at different positions, thereby comprehensively improving the pressure-maintaining effect on the pressure-bearing object 2.

[0041] In some embodiments, the adjusting portion 14 is a flexible structure, for example, the adjusting portion 14 is made of rubber or silicone. When the adjusting portion 14 is squeezed on the pressure-bearing object 2, the adjusting portion 14 undergoes a certain elastic deformation, increasing the contact area with the pressure-bearing object 2 and dispersing the pressure, which is beneficial to keeping the pressure-bearing object 2 flat and preventing the pressure-bearing object 2 from warping at the position under pressure.

[0042] According to a preferred embodiment of the present invention, the circumferential position of the adjusting portion 14 on at least one first roller 12 matches the shape of the pressure-bearing object 2 so that at least one first roller 12 and at least part of the adjusting portion 14 are pressed onto the pressure-bearing object 2.

[0043] like Figure 1 As shown, the folded edges of the pressure-bearing object 2 have a large springback and require a higher pressure-maintaining force. The central portion of the pressure-bearing object 2, on the other hand, is a single-layer plate material, requiring less pressure-maintaining force. In this embodiment, adjustment portions 14 can be provided on the edges of the first roller 12 to increase the pressure applied to the edges of the pressure-bearing object 2. Depending on the pressure-bearing object 2, the adjustment portions 14 can be removed from the first roller 12, replaced, or relocated.

[0044] In some embodiments, a guiding structure or a positioning structure can be provided on the mating portion 13 to align the position of the pressure-bearing object 2 on the mating portion 13 with the position of the adjusting portion 14 on the first roller 12, thereby preventing the adjusting portion 14 from deviating from the position of the pressure-bearing object 2 requiring greater pressure, thereby affecting the pressure-maintaining effect. Specifically, the guiding structure or the positioning structure on the mating portion 13 can be a limiting groove of a preset shape, which confines the pressure-bearing object 2 within the limiting groove. Alternatively, the mating portion 13 includes an adsorption structure, and after the position of the pressure-bearing object 2 is adjusted to align with the position of the adjusting portion 14 on the first roller 12, the adsorption structure is used to adsorb the pressure-bearing object 2 onto the mating portion 13, and the position is kept fixed.

[0045] In a preferred embodiment of the present invention, the adjusting portion 14 surrounds at least a portion of the at least one first roller 12. Figure 1 As shown in FIG, the adjusting portion 14 is annularly encircling both ends of the first roller 12. Encircling the adjusting portion 14 around the first roller 12 enhances the bonding strength between the adjusting portion 14 and the first roller 12 and simplifies the installation process. For example, the adjusting portion 14 is sleeved around the circumference of the first roller 12. This embodiment prevents the adjusting portion 14 from being detached or displaced due to lateral extrusion (the reaction force to the force acting on the pressure-bearing object 2), which could affect the structural stability of the rolling device 1 or even damage the pressure-bearing object 2.

[0046] In other embodiments, the adjusting portion 14 protrudes from the outer surface of the first roller 12 and has a smooth curved or flat surface. As the first roller 12 rotates, the distance between the adjusting portion 14 and the mating portion 13 gradually decreases, and the pressure on the load 2 gradually increases, which helps prevent the adjusting portion 14 from falling off or becoming misplaced from the first roller 12. The adjusting portion 14 can be attached to the circumference of the first roller 12 by means of snap-fitting, magnetic attraction, or adhesive bonding.

[0047] According to a preferred embodiment of the present invention, the size of the adjusting portion 14 in the radial direction of at least one first roller 12 is adjustable. For example, the adjusting portion 14 has a cavity, and the size of the adjusting portion 14 in the radial direction of the first roller 12 can be increased by inflating the interior of the adjusting portion 14. Alternatively, the adjusting portion 14 is replaceable in the circumferential direction of at least one first roller 12. For example, the adjusting portion 14 can be removed from the circumference of the first roller 12 and an adjusting portion 14 of a different size can be installed in the circumferential direction of the first roller 12.

[0048] By changing the radial size of the adjusting portion 14 on the first roller 12, or replacing the adjusting portion 14 with another size, the magnitude of the pressure acting on the pressure-bearing object 2 or the position of the pressure acting on the pressure-bearing object 2 can be changed, making it suitable for different pressure-bearing objects 2 and improving the application range of the rolling device 1.

[0049] According to a preferred embodiment of the present invention, Figure 1 As shown, the outer surface of the adjusting portion 14 is an arcuate surface, and the outer side surface of the adjusting portion 14 is coaxial with the outer side surface of the first roller 12. That is, the center of the arcuate surface of the adjusting portion 14 is the rotation axis of the first roller 12. During the rotation of the first roller 12, the distance between the outer side surface of the adjusting portion 14 and the mating portion 13 remains constant within the range of the adjusting portion 14, and the pressure applied to the pressure-bearing object 2 remains stable.

[0050] In a preferred embodiment of the present invention, Figure 1 As shown, at least one first roller 12 is movable relative to the bracket 11 in a plane perpendicular to the axial direction of the first roller 12. For example, the axial direction of the first roller 12 is arranged horizontally, and the first roller 12 is arranged to be movable relative to the bracket 11 in a plane perpendicular to the horizontal direction. Preferably, the first roller 12 is arranged to be movable in the vertical direction.

[0051] In other embodiments of the present invention, the matching portion 13 is configured to be movable relative to the bracket 11 in a plane perpendicular to the axial direction of the first roller 12. Figure 1 As shown in FIG, the position of the matching portion 13 can be adjusted in the vertical direction to change the distance between the matching portion 13 and the first roller 12.

[0052] By changing the distance between the first roller 12 and the mating portion 13, the pressure acting on the pressure-bearing object 2 can be changed, which is suitable for different pressure-bearing objects 2, or provides different pressure-maintaining effects for the pressure-bearing object 2, such as preventing excessive pressure from causing damage to the pressure-bearing object 2, thereby improving the applicability of the rolling device 1.

[0053] like Figure 2As shown, according to a preferred embodiment of the present invention, the matching portion 13 includes at least one second roller 131 , and the axial direction of the at least one second roller 131 is parallel to the axial direction of the at least one first roller 12 .

[0054] In this embodiment, the second roller 131 and the first roller 12 are positioned adjacent to each other, with the pressure object 2 positioned between them. The first and second rollers 12, 131 jointly apply pressure to the pressure object 2. The radial dimensions of the first and second rollers 12, 131 may be the same or different. At least one of the first and second rollers 12, 131 is driven by a drive device 15. When the other of the first and second rollers 12, 131 is unpowered, it can rotate driven by the pressure object 2.

[0055] Preferably, the distance between the first roller 12 and the second roller 131 can be adjusted. For example, when the first roller 12 is close to the second roller 131 , the pressure acting on the pressure-bearing object 2 will be increased.

[0056] In some embodiments, the first rollers 12 and the second rollers 131 are arranged in pairs, the number of the first rollers 12 and the second rollers 131 are equal, and they are aligned one by one in the vertical direction. In other embodiments, the rolling device 1 includes a plurality of first rollers 12, the matching portion 13 includes at least one second roller 131, and the matching portion 13 also includes a plane capable of providing support, such as a platform or a conveyor belt with a pad underneath. Some of the first rollers 12 and the second rollers 131 correspond one by one and are aligned in the vertical direction. Another portion of the first rollers 12 corresponds to the position of the plane in the matching portion 13 that can support the pressure-bearing object 2, and the pressure-bearing object 2 is subjected to the combined pressure of the first rollers 12 and the plane.

[0057] In some embodiments, the second roller 131 is a cylindrical roller with uniform radial direction. When the pressure-bearing object 2 passes between the first roller 12 and the second roller 131 , the second roller 131 can be regarded as providing planar support or arcuate support to the pressure-bearing object 2 .

[0058] In other embodiments, the adjusting portion 14 is further detachably provided on the circumference of at least one second roller 131 , and the adjusting portion 14 is configured to be able to change the radial dimension of at least a portion of the second roller 131 .

[0059] The position of the adjusting portion 14 provided on the first roller 12 and the position of the adjusting portion 14 provided on the second roller 131 can be aligned in the vertical direction, or can be offset in the vertical direction, or can partially overlap. When the position of the adjusting portion 14 provided on the first roller 12 and the position of the adjusting portion 14 provided on the second roller 131 can be offset in the vertical direction, or can partially overlap, the first roller 12 and the second roller 131 can also be used to assist in forming the pressure-bearing object 2.

[0060] like Figure 1 As shown, according to other embodiments of the present invention, the cooperating portion 13 further includes a conveyor belt 132, which drives the pressure-bearing object 2 to move toward at least one first roller 12, and a support structure is provided at a position in the conveyor belt 132 corresponding to at least one first roller 12, and the support structure and the first roller 12 cooperate with each other to jointly apply pressure to the pressure-bearing object 2.

[0061] Finally, it should be noted that the above description is merely an embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
