Description

Technical Field

[0001] This utility model relates to the field of automated ceramic tile packaging technology, and in particular to a paper-folding device for wrapping ceramic tiles. Background Technology

[0002] In the field of building ceramics (tile) production and logistics, after the fired tiles are stacked into neat piles, cardboard is typically used to wrap and seal the four sides of the pile to protect the edges and corners from damage during subsequent transportation and storage. Currently, the industry widely uses automated cardboard wrapping equipment to achieve this packaging process. These devices can basically complete the automatic feeding and positioning of the cardboard, as well as the folding and wrapping of the main parts of the sides of the pile.

[0003] However, existing brick stack wrapping devices have a significant technical flaw: a lack of effective and precise wrapping mechanisms for the four critical corners of the brick stack. Specifically, during the wrapping process, the device often fails to ensure a tight and smooth folding of the cardboard at the sharp corners of the brick stack. This results in unevenness in the corner areas of the packaged brick stack, often with cardboard hanging, wrinkled, insufficiently folded, or loosely wrapped. This unevenness in corner packaging directly affects the overall quality and stability of the packaging. When these packaged brick stacks enter the transportation or warehousing stages (such as multi-layer stacking or stacking in a warehouse), the unevenness at the corners prevents the brick stacks from being securely stacked, resulting in poor overall stack stability. This increases the risk of collapse during transportation and reduces the maximum stacking height in the warehouse, directly leading to a serious waste of valuable storage and transport vehicle space and increasing logistics costs.

[0004] Therefore, developing a paper wrapping device that can effectively solve the problem of precise cardboard wrapping at the corners of brick stacks and ensure that the corners are flat and stable after packaging is of urgent practical need and important economic value for improving the automation level of building ceramic product packaging, ensuring transportation safety, and optimizing warehousing and logistics efficiency. Utility Model Content

[0005] In response to the problems raised in the background art, the purpose of this utility model is to propose a paper-folding device for wrapping ceramic tiles, which solves the problem that existing paper-folding devices do not have a corner paper-folding mechanism, resulting in loose wrapping of ceramic tiles and low packaging quality.

[0016] Preferably, the first flanged part includes a connecting end and a pressing end;

[0017] The connecting end is connected to the first flanging shaft. When the first flanging mechanism performs the first fold, the pressing end abuts against the cardboard on the top surface of the tile.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] The following is in conjunction with the appendix Figures 1 to 7 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0041] The process of wrapping tiles typically involves placing stacked tiles on top of cardboard, either manually or using a robotic arm. At this point, the bottom of the stack has protruding cardboard sections around its perimeter. By folding these protruding cardboard sections upwards along the edges of the stack, covering the sides and top edge, the tiles (brick stack) are wrapped (packed). This invention provides a folding device for wrapping tiles, featuring a folding station 0, including two first flanging mechanisms 2, two second flanging mechanisms 3, and four corner folding mechanisms 4. The two first flanging mechanisms 2 are located at the front and rear ends of the folding station 0, the two second flanging mechanisms 3 are located on the left and right sides of the folding station 0 facing each other, and the four corner folding mechanisms 4 are located at the four corners of the folding station 0. The two first flanging mechanisms 2 are used to perform a first fold on the cardboard at the front and rear ends of the tile, the corner folding mechanisms 4 are used to fold the left and right sides of the cardboard after the first fold, and the two second flanging mechanisms 3 are used to perform a second fold on the cardboard on the left and right sides of the tile. By employing multiple sets of flanging and corner-folding mechanisms working in tandem, the problem of loose corner wrapping during the tile wrapping process is effectively addressed.

[0042] Specifically, two first-folding mechanisms 2 are located at the front and rear ends of the folding station 0. They simultaneously fold the cardboard at the front and rear ends to form the initial wrapping of the front and rear ends of the tile. Subsequently, four corner-folding mechanisms 4 fold the cardboard protruding from the left and right sides of the tile after the first fold at the four corners of the folding station 0, eliminating the suspension and wrinkling phenomenon that occurs when folding corners in traditional folding devices. Finally, two second-folding mechanisms 3 fold the cardboard located on the left and right sides of the tile. The second folding process covers the corners previously folded by the corner-folding mechanisms 4, pressing the corners together and completing the overall wrapping of the tile. The entire process establishes the basic wrapping shape through the first fold, the corner-folding mechanisms precisely handle the corner folds, and the second fold completes the overall packaging of the tile. The second fold also strengthens the wrapping stability of the corners, ensuring that the cardboard forms a tight and flat folding structure on the four sides and corners of the tile, avoiding the problem of unstable stacking caused by loose corner wrapping.

[0043] Compared to existing technologies, traditional origami devices rely solely on four folding mechanisms (front, back, left, and right) to complete the wrapping process, lacking an independent corner folding step. This results in corner cardboard being formed naturally through the folding action of adjacent mechanisms, failing to eliminate gaps caused by material springback. This solution adds four corner folding mechanisms 4 and optimizes the action sequence, incorporating a corner folding process between the front / back folding and the left / right folding. This ensures precise corner folds are formed in the cardboard corner areas, providing a geometric basis for subsequent pressing.

[0044] Through the above technical solution, this application solves the problem of unstable stacking caused by loose corner wrapping of tiles, enabling the cardboard to form a gapless bonding structure in the corner area, thus improving the overall flatness of the tile packaging. The corner wrapping of tiles treated by the corner folding mechanism 4 has a high degree of corner bonding and flatness, which can meet the requirements of neat stacking and placement of large quantities of packages during warehousing, improving space utilization; at the same time, neat stacking can also prevent tipping during warehousing or transportation, improving the production safety factor.

[0045] Furthermore, the corner folding mechanism 4 includes a corner folding drive 41 and a corner folding assembly 42. The corner folding drive 41 is used to drive the corner folding assembly 42 to move in the front-back direction, so that the side of the cardboard after the first fold is completed fits with the side of the tile to form a corner.

[0046] By cooperating with the corner folding drive 41, which has linear driving capability, and the corner folding assembly 42, precise folding of the cardboard at the corner of the tile is achieved. The axial driving characteristic of the corner folding drive 41 allows it to precisely control the displacement of the corner folding assembly 42 in the front-back direction, ensuring that when the corner folding assembly 42 reaches the predetermined working position, the side of the cardboard that has completed the first fold is accurately pressed to completely fit the side (left / right side) of the tile. The structural design of the corner folding assembly 42 allows it to gradually guide the free edge of the cardboard to the side wall of the tile during movement, and form a fold angle that conforms to the geometry of the tile corner through mechanical limiting. This linear advancement method in the front-back direction avoids the cardboard misalignment or wrinkling problems caused by traditional rotational folding. Especially for wrapping the right-angle part of the tile, this technology can form a gapless and tightly wrapped corner at the fold, thereby improving the flatness and structural stability of the corner after packaging.

[0047] Furthermore, the angle assembly 42 includes an angle mounting base 421, an angle member 422, and a torsion spring;

[0048] The angle mounting base 421 is mounted on the driving end of the angle driving component 41;

[0049] The corner folding component 422 is L-shaped and includes a corner folding push plate 4221 and a connecting plate 4222 that are perpendicular to each other. The connecting plate 4222 is hinged to the corner folding mounting base 421 via a hinge shaft. A torsion spring is sleeved on the hinge shaft. One end of the torsion spring abuts against one side of the corner folding push plate 4221, and the other end of the torsion spring abuts against the corner folding mounting base 421. The other side of the corner folding push plate 4221 is parallel to the side of the ceramic tile located at the folding station 0.

[0050] The corner folding component 42 with a specific structure enables the cardboard to adaptively fit the corner of the tile (brick stack). The corner folding mounting base 421 is connected to the driving end of the corner folding drive component 41, enabling the corner folding component 42 to move and position itself forward and backward, providing a basic motion path for corner folding. The special geometry of the L-shaped corner folding component 422 allows its corner folding push plate 4221 to accurately correspond to the spatial shape of the side of the tile. The cooperation between the connecting plate 4222 and the hinge shaft gives the corner folding push plate 4221 the freedom to rotate around the hinge shaft, while the bidirectional abutment structure of the torsion spring maintains the working angle of the corner folding push plate 4221 through elastic preload. When the corner folding drive 41 pushes the corner folding assembly 42 towards the corner of the tile, before the corner folding push plate 4221 contacts the cardboard, the side of the corner folding push plate 4221 away from the connecting plate 4222 is always parallel to the side of the tile within the folding station 0. This ensures the accuracy of folding the cardboard into a corner after contact with the cardboard. After contact with the cardboard, the resistance of the cardboard to the corner folding push plate 4221 causes the corner folding assembly 422 to rotate slightly around the hinge axis. At this time, the torsion spring generates a reverse torque to balance the external resistance. When the corner folding push plate 4221 pushes the cardboard completely against the side of the tile, the preload of the torsion spring keeps the corner folding push plate 4221 in contact with the side of the tile. In this dynamic balancing process, the corner folding push plate 4221 ensures the accuracy of folding the cardboard, overcomes the rebound force generated by the elastic deformation of the cardboard, and avoids crushing or wrinkling of the cardboard caused by rigid contact.

[0051] Furthermore, the first flanging mechanism 2 includes a first flanging seat 21, a first flanging drive 22, a first flanging shaft 23, and a plurality of first flanging parts 24;

[0052] The first flanging shaft 23 is rotatably disposed on the top of the first flanging seat 21. The first flanging shaft 23 extends in the left and right direction. A plurality of first flanging parts 24 are spaced apart on the first flanging shaft 23. The first flanging drive 22 is installed on the first flanging seat 21. The first flanging drive 22 is used to drive the first flanging shaft 23 to rotate, thereby causing the first flanging parts 24 to perform the first folding on the cardboard.

[0053] By constructing a transmission-type flanging mechanism, efficient and synchronous folding of the front and rear ends of the tile cardboard is achieved. The first flanging seat 21 serves as the basic support platform for the first flanging mechanism 2. A first flanging shaft 23 extending in the left and right direction is set at the top to form a transverse rotation axis. The left and right extension of the first flanging shaft 23 allows multiple spaced first flanging pieces 24 mounted on it to cover the entire edge line of the front and rear ends of the tile. The transmission system composed of the first flanging drive 22 and the first flanging shaft 23 drives all the first flanging pieces 24 to move synchronously through the rotation of the drive shaft, ensuring that the cardboard is subjected to uniform force and moves synchronously during the folding process at both ends.

[0054] Multiple first-flanging components 24 spaced apart form continuously distributed force application points when the first-flanging shaft 23 rotates. This not only avoids situations where some parts are not folded but also prevents excessive pressure from damaging the cardboard. This axially driven structural design is particularly suitable for long strip folding operations. Through mechanical linkage, it achieves coordinated operation of multiple contact points, providing a flat and reliable folding foundation for subsequent corner folding processes.

[0055] Furthermore, the first flange member 24 includes a connecting end 241 and a pressing end 242;

[0056] The connecting end 241 is connected to the first flanging shaft 23. When the first flanging mechanism 2 performs the first folding, the pressing end 242 abuts against the cardboard on the top surface of the tile.

[0057] Precise cardboard positioning and stable folding are achieved through a first flange member 24 with a specific structure. The connecting end 241 is a rigid structural component connecting the first flange member 24 and the first flange shaft 23. It can be implemented using a sleeve-type snap-fit ​​structure or a flange bolt connection to ensure the synchronization and stability of power transmission. The pressing end 242 is an end component with a contact surface, which can be implemented using a flat pressing plate, a curved pressing block, or a roller. The contact surface can be optionally equipped with an elastic rubber layer or a silicone anti-slip layer to form a limiting contact with the cardboard during folding.

[0058] The rigid connection between the connecting end 241 and the first flanging shaft 23 ensures the stability of power transmission in the first folding action, allowing multiple first flanging components 24 to act synchronously on the cardboard. The design of the pressing top end 242, which directly presses against the cardboard on the top surface of the tile during the first fold, can precisely limit the edge of the cardboard at the moment of folding. This not only prevents the cardboard from shifting during the folding process, but also enhances the shaping effect of the cardboard crease through the reaction force generated by the top surface contact. This dual-action mechanism not only ensures the completion quality of the first folding process, but also provides a precise processing basis for the subsequent corner folding mechanism 4 and the second flanging mechanism 3, thereby avoiding corner wrapping defects caused by the accumulation of errors in the previous process.

[0059] It is worth noting that, Figure 2 and Figure 3 The first flanging mechanism 2 is set at the front end of the origami station 0.

[0060] Furthermore, the second flanging mechanism 3 includes a second flanging seat 31, a lifting component 32, and a second folding component 33, wherein the second folding includes upward folding and inward folding;

[0061] The lifting component 32 is used to fold the cardboard on the side of the tile upwards, and the second folding component 33 is used to fold the cardboard inwards after the upward folding is completed.

[0062] The lifting component 32, through a vertical upward movement, first raises the cardboard on the side of the tile from a horizontal to a vertical position. This operation not only forms an initial wrap around the side of the tile but also further covers the previously formed folded corner. The second folding component 33 performs a horizontal inward fold on the vertically raised cardboard surface, pushing the cardboard towards the center of the tile to wrap the (left and right) sides of the tile. The spatial coordination of the lifting component 32 and the second folding component 33 ensures that the cardboard on the side of the tile first forms a support surface perpendicular to the side of the tile, and then, through horizontal pressing, forms a wrapping shape that fits tightly against the top surface of the tile. By performing two folding actions in different directions in two steps, a three-dimensional wrapping of the cardboard on the side of the tile is achieved.

[0063] Furthermore, the lifting assembly 32 includes a lifting drive 321 and a lifting plate 322. The lifting drive 321 is installed on the lower part of the second flange seat 31, and the lifting plate 322 is installed on the driving end of the lifting drive 321. The lifting drive 321 is used to drive the lifting plate 322 to rise.

[0064] The second folding assembly 33 includes a second folding drive 331 and a second folding push rod 332. The second folding drive 331 is mounted on the upper part of the second folding seat 31, and the second folding push rod 332 is mounted on the drive end of the second folding drive 331. The second folding drive 331 is used to drive the second folding push rod 332 to push towards the center of the tile.

[0065] The lifting drive component 321 is a power element capable of generating vertical linear motion, specifically a cylinder or hydraulic cylinder. Located below the second flange seat 31, it provides vertical lifting power to the lifting plate 322. The lifting plate 322 is a rigid component with a flat contact surface, specifically made of metal sheet or engineering plastic sheet. It applies an initial lifting force to the cardboard through vertical lifting action. The lifting assembly 32 first lifts the side cardboard of the tile upward to form a preliminary fold (upward fold). This lifting action can prevent the cardboard from shifting due to lateral force in the initial stage.

[0066] The second folding drive component 331 is a power element capable of generating horizontal linear thrust, which can be implemented using a cylinder or a linear motor. It is located on the upper part of the second folding seat 31 to provide horizontal pushing power. The second folding push rod 332 is a rod-shaped pushing component extending in a specific direction, which can be implemented using a stainless steel tube or aluminum alloy profile. Its linear path forms a spatial orthogonal relationship with the movement direction of the lifting plate 322. The second folding assembly 33 is located on the upper part of the lifting assembly 32. By driving the second folding push rod 332 horizontally, it pushes the already folded cardboard towards the center of the tile, causing the already folded cardboard to fold inward. The structure of the two sets of drive components arranged in upper and lower layers ensures the independence of the lifting action and the pushing action, and avoids mechanical interference through spatial misalignment design.

[0067] Furthermore, the second folding push rod 332 extends in the front-to-back direction.

[0068] By setting the extension direction of the second folding push rod 332 to the front-to-back direction, the second folding push rod 332 can form a spatial orthogonal relationship with the folding direction of the cardboard on the left and right sides of the tile when it is in motion. When the second folding drive member 331 pushes the second folding push rod 332 towards the center of the tile, the second folding push rod 332, which extends along the front-to-back direction, can apply a uniform pushing force to the cardboard that has been folded upwards with a movement trajectory parallel to the side of the tile. This spatial layout design ensures that the force direction of the cardboard during the inward folding process remains perpendicular to the folding line, thereby avoiding the cardboard twisting and deformation caused by the oblique force applied by the second folding push rod 332.

[0069] Furthermore, the two bending mechanisms 4 are installed at the front and rear ends of the second flange seat 31.

[0070] By directly integrating the two corner-folding mechanisms 4 into the front and rear ends of the second flange seat 31, the spatial layout is optimized and the process connection is improved. Specifically, the four corner-folding mechanisms 4 are installed in pairs at the front and rear ends of the second flange seat 31 on the left and right sides.

[0071] It is worth noting that, Figure 4 and Figure 5The second flanging mechanism 3 is shown, located to the left of the origami station 0.

[0072] Furthermore, it also includes two conveying mechanisms 1, which extend in the front-to-back direction and are arranged opposite to each other, for conveying the tile to the folding station 0;

[0073] Two first flanging mechanisms 2 are disposed between the two conveying mechanisms 1, and two second flanging mechanisms 3 are disposed on the outside of the two conveying mechanisms 1.

[0074] Two conveying mechanisms 1, extending along the front-to-back direction, form a symmetrical conveying channel. Their relative spatial arrangement enables synchronous conveying of the tiles, ensuring positional accuracy at the folding station. Two first-flipping mechanisms 2 are positioned between the two conveying mechanisms 1, preserving sufficient front-to-back operating space at the folding station while preventing interference between the first-flipping mechanisms 2 and the conveying path, providing stable support for the first folding action of the cardboard at both ends. Two second-flipping mechanisms 3 are arranged on the outer sides of the two conveying mechanisms 1, independently completing the folding process of the cardboard on the left and right sides using the extended space on both sides of the conveying mechanism 1. This creates a spatially nested layout between the mechanical structure of the conveying mechanism 1 and the folding execution mechanism, optimizing the overall compactness of the device while ensuring conveying accuracy.

[0075] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
