Abstract
Description
Technical Field
[0001] This utility model relates to the field of label folding technology, and in particular to a folding mechanism for producing double-sided QR code labels. Background Technology
[0002] In the existing manufacturing industry, most products, such as 3C products, need to be labeled with QR codes for easy recording and traceability. Each product is identified and recorded to facilitate management and traceability during product production, and to identify the problem point after a product problem occurs.
[0003] Some products need to be flipped during production and material collection, so double-sided QR codes need to be attached to the products to facilitate scanning and recording from different directions on both sides of the product at the same time. For this purpose, two QR codes need to be printed on a label and folded to form a double-sided QR code. In the label preparation process, each label needs to be folded. In the existing technology, folding is mostly done manually. However, in large-scale production, manual folding is labor-intensive and inefficient. Utility Model Content
[0004] To improve label folding efficiency, this application provides a folding mechanism for producing double-sided QR code labels.
[0005] The folding mechanism for producing double-sided QR code labels provided in this application adopts the following technical solution:
[0006] A folding mechanism for producing double-sided QR code labels includes a base, a pre-lifting block, and a flattening block. Both the pre-lifting block and the flattening block are mounted on the base. The base is equipped with a driving assembly for moving the label. The pre-lifting block has a pre-lifting groove for the label to pass through, and the flattening block has a flattening groove for the label to pass through. A pre-lifting auxiliary block with a pre-lifting inclined surface is disposed within the pre-lifting groove. A flattening auxiliary block with a flattening inclined surface is disposed within the flattening groove. The driving assembly includes a driving roller rotatably mounted on the base, capable of flattening the folded label.
[0007] By adopting the above technical solution, the label passes through the pre-lifting groove and the flattening groove in sequence under the drive of the drive component. During the process of the label passing through the pre-lifting groove, it is guided by the pre-lifting inclined surface on the pre-lifting auxiliary block, which causes the label to bend at a certain angle. When the label passes through the flattening groove, the flattening inclined surface on the flattening auxiliary block flattens the bent label. The subsequent label is flattened by the drive roller, thus completing the folding. This allows the label to bend and fold gradually during the movement, making the operation simple and convenient, reducing labor intensity, and continuously folding, thereby improving the label folding efficiency.
[0008] Preferably, the base is provided with a straightening block, which is disposed between the pre-lifting block and the flattening block. The straightening block is provided with a straightening groove, and a straightening auxiliary block is disposed in the straightening groove. The straightening auxiliary block is provided with a straightening vertical surface.
[0009] By adopting the above technical solution, after the label moves through the pre-lifting groove and bends at a certain angle, it passes through the straightening groove and is further deformed by the straightening auxiliary block in the straightening groove, which straightens the vertical surface, so that the bending angle is close to 90°. This makes it easier for the label to enter the flattening groove and be flattened by the flattening auxiliary block, improving the smoothness of label folding, reducing the possibility of the label bending too fast and getting stuck during the folding process, and improving the stability and quality of label folding.
[0010] Preferably, the base is provided with an assembly block and an installation component, the installation component being used to install the assembly block on the base, the assembly block being provided with an assembly groove, and the pre-lifting block, straightening block and flattening block being disposed in the assembly groove.
[0011] By adopting the above technical solution, the pre-lifting block, straightening block and flattening block are all set in the assembly slot. The assembly block is installed on the base by the installation component, which is convenient for disassembly, thereby facilitating the cleaning and repair of the pre-lifting block, straightening block and flattening block.
[0012] Preferably, the mounting assembly includes a mounting block and mounting bolts, the mounting block being disposed on the assembly block and fitting against the base, and the mounting bolts being used to mount the mounting block onto the base.
[0013] By adopting the above technical solution, the assembly block is placed on the base and the mounting block is pressed against the base. Then, the mounting bolts are installed to install the assembly block on the base. The operation is simple and convenient, and the stability of the assembly block installation is improved, thereby improving the stability of the label movement and folding.
[0014] Preferably, the inner wall of the assembly groove is provided with a dovetail groove, and the pre-lifting block, straightening block and flattening block are all provided with dovetail blocks, and the dovetail blocks can be slidably inserted into the dovetail groove.
[0015] By adopting the above technical solution, the pre-lifting block, straightening block, and flattening block are all slidably inserted into the dovetail groove via dovetail blocks, which facilitates disassembly and replacement. At the same time, the insertion of the dovetail blocks into the dovetail groove can effectively position and limit the positions of the pre-lifting block, straightening block, and flattening block, reducing the possibility of the pre-lifting block, straightening block, and flattening block shifting and damaging the label, and improving the quality of label folding.
[0016] Preferably, the drive assembly further includes a drive motor, which is mounted on the base and the drive motor shaft is connected to the drive roller.
[0017] By adopting the above technical solution, the drive motor is started to drive the drive roller to rotate, which in turn, in conjunction with the pressure on the base surface, drives the label to move forward, thereby realizing label driving. At the same time, the pressure of the drive roller on the label can further enhance the label flattening effect. The operation is simple and convenient, and easy to use.
[0018] Preferably, the base is provided with a limiting rod, and the limiting rod and the drive roller are arranged on both sides of the pre-lifting block.
[0019] By adopting the above technical solution, the limiting rod is used to hold the label in place, so that the label remains in contact with the base surface before entering the pre-lifting slot, thereby improving the stability of the label's posture when it enters the pre-lifting slot and begins to fold, reducing the possibility of the label bulging affecting the folding, and improving the label folding quality.
[0020] Preferably, the base is provided with a limiting block, which is located on the side of the limiting rod away from the pre-lifting block.
[0021] By adopting the above technical solution, the limiting block is used to hold the label against the label from both sides, thereby reducing the possibility of the label tilting or twisting during movement, improving the stability of the label's posture when it enters the pre-lifting slot and begins to fold, and ensuring the quality of the label folding.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. By setting up a base, pre-lifting block, flattening block, drive component, pre-lifting groove, pre-lifting auxiliary block, pre-lifting inclined surface, flattening auxiliary block, flattening groove and flattening inclined surface, the label is driven forward by the drive component on the base. The label passes through the pre-lifting groove of the pre-lifting block and the flattening groove of the flattening block in sequence. During this process, the label is first squeezed and bent into an obtuse angle by the pre-lifting inclined surface of the pre-lifting auxiliary block, and then squeezed into an acute angle by the flattening inclined surface of the flattening auxiliary block, thus completing the folding work. The operation is simple and convenient, and the efficiency of large-scale folding is higher than that of manual folding.
[0024] 2. By setting up a straightening block, a straightening groove, a straightening auxiliary block, and a straightening vertical surface, the label is squeezed and bent into an obtuse angle by the pre-lifting inclined surface of the pre-lifting auxiliary block, and then enters the straightening groove of the straightening block. In the straightening groove, it is squeezed by the straightening vertical surface of the straightening auxiliary block, so that the label is bent into a right angle. This makes it easier for the subsequent flattening auxiliary block to squeeze and bend the label into an acute angle, improving the smoothness of label folding.
[0025] 3. By setting up assembly blocks, assembly slots, dovetail blocks, dovetail grooves, and mounting components, the assembly blocks are installed on the base via the mounting components. At the same time, the pre-lifting blocks, straightening blocks, and flattening blocks are all slidably inserted into the dovetail grooves via the dovetail blocks, so that the pre-lifting blocks, straightening blocks, and flattening blocks can all be assembled into the assembly slots of the assembly blocks. Assembly and disassembly are very convenient. At the same time, by inserting the dovetail blocks into the dovetail grooves, the positions of the pre-lifting blocks, straightening blocks, and flattening blocks are positioned, reducing the possibility that the skew of the pre-lifting blocks, straightening blocks, and flattening blocks will affect the label folding and improving folding efficiency.

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0031] This application discloses a folding mechanism for producing double-sided QR code labels. (See also...) Figures 1 to 3It includes a base 1 and a drive assembly 7. The drive assembly 7 is used to drive the label to move. The base 1 is provided with a pre-lifting block 3, a straightening block 4 and a flattening block 5. The side wall of the pre-lifting block 3 is provided with a pre-lifting groove 31 that communicates with the bottom wall for the label to pass through. The top wall of the pre-lifting groove 31 is provided with four triangular pre-lifting auxiliary blocks 32, and the pre-lifting auxiliary blocks 32 are provided with pre-lifting inclined surfaces 33. The side wall of the flattening block 5 is provided with a flattening groove 51 that communicates with the bottom wall for the label to pass through. The top wall of the flattening groove 51 is provided with four triangular flattening auxiliary blocks 52, and the flattening auxiliary blocks 52 are provided with flattening inclined surfaces 53. The flattening inclined surfaces 53 and the pre-lifting inclined surfaces 33 have opposite inclination directions. A straightening block 4 is positioned between the pre-lifting block 3 and the flattening block 5. A straightening groove 41, communicating with the bottom wall, is provided through the side wall of the straightening block 4 for the label to pass through. Four triangular straightening auxiliary blocks 42 are provided on the top wall of the straightening groove 41, each with a straightening vertical surface 43, which is vertically oriented. The lowest points of the pre-lifting auxiliary block 32, the straightening auxiliary block 42, and the flattening auxiliary block 52 are aligned. The label paper passes sequentially through the pre-lifting groove 31, the straightening groove 41, and the flattening groove 51. During subsequent label paper movement, the pre-lifting inclined surface 33, the straightening vertical surface 43, and the flattening inclined surface 53 sequentially compress the label paper, thus folding it. Combined with the movement of the label paper, folding can be performed quickly and efficiently.
[0032] To improve the quality and stability of folding, refer to Figure 2 and Figure 3 The base 1 is provided with an assembly block 2 and a mounting component 6. The mounting component 6 is used to mount the assembly block 2 onto the base 1. The side wall of the assembly block 2 is provided with an assembly groove 21 that communicates with the bottom wall. The pre-lifting block 3, straightening block 4, and flattening block 5 can all be inserted into the assembly groove 21. The top wall of the assembly groove 21 is provided with a dovetail groove 22 that is wider at the top and narrower at the bottom. The top walls of the pre-lifting block 3, straightening block 4, and flattening block 5 are all integrally fixed with dovetail blocks 221 that are wider at the top and narrower at the bottom. The dovetail blocks 221 can be slidably inserted into the dovetail groove 22. The mounting component 6 includes a mounting block 61 and a mounting bolt 62. The mounting block 61 is integrally fixed on the side walls of both sides of the assembly block 2 and abuts against the surface of the base 1. The mounting bolt 62 is used to fix the mounting block 61 to the base 1. By inserting the dovetail block 221 into the dovetail groove 22 to position the pre-lifting block 3, straightening block 4, and flattening block 5, the possibility of the pre-lifting block 3, straightening block 4, and flattening block 5 being misaligned and affecting the folding quality of the label paper is reduced, and the stability of the folding is improved.
[0033] To improve folding quality, refer to Figure 1The drive assembly 7 includes a drive roller 72 and a drive motor 71. The drive roller 72 is rotatably mounted on the base 1 and is positioned on the side of the flattening block 5 away from the straightening block 4. The drive motor 71 is fixedly mounted on the base 1, and its shaft is coaxially and fixedly connected to the drive roller 72. Four pressing rings 721 are fixedly sleeved on the drive roller 72. The pressing rings 721 are used to press and fold the label and push the label to move. The drive motor 71 drives the drive roller 72 to rotate, and the pressing rings 721 squeeze the label, thereby pushing the label to move. At the same time, the pressing rings 721 further compress the folded label when squeezing it, thereby improving the folding quality.
[0034] To improve the stability of folding, refer to Figure 1 A square limiting rod 11 is fixedly installed on the base 1. A gap is left between the bottom of the limiting rod 11 and the base 1 for the label to pass through. A blade for cutting the label paper is provided at the bottom of the limiting rod 11. The base 1 is provided with a pair of limiting blocks 12 to limit the movement trajectory of the label paper from both sides. The limiting rod 11 is located on the side of the pre-lifting block 3 away from the straightening block 4, and the limiting block 12 is located on the side of the limiting rod 11 away from the pre-lifting block 3. By limiting the movement trajectory of the label from the left and right by the limiting blocks 12, and by smoothing the label surface by the limiting rod 11 to reduce protrusions, the stability of label movement is improved, thereby improving the stability of label folding.
[0035] The implementation principle of a folding mechanism for producing double-sided QR code labels according to an embodiment of this application is as follows: After the label passes through the pre-lifting groove 31, the straightening groove 41 and the flattening groove 51 in sequence, the drive motor 71 is started to drive the drive roller 72 to rotate, thereby moving the label through the pressing ring 721. When the subsequent label passes through the pre-lifting groove 31, the straightening groove 41 and the flattening groove 51, it is successively squeezed by the pre-lifting inclined surface 33, the straightening vertical surface 43 and the flattening inclined surface 53, thereby causing the label to fold gradually. When the label paper leaves the pressing groove, it continues to be pressed by the pressing ring 721, thereby completing the folding of the label paper. With the movement of the label paper, folding can be carried out quickly and efficiently.
[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
