Description

Technical Field

[0001] This invention relates to the field of express delivery waybill production, and specifically to a printing process method for express delivery waybills. Background Technology

[0002] A courier waybill is a document used in the courier industry to record information such as the sender, recipient, product weight, and price during the delivery of goods. Current courier waybills consist of a label layer, an adhesive layer, and a release layer. During use, the release layer is removed and attached to the packaging box. Since the packaging box is generally discarded by the recipient, those concerned about privacy may tear off the waybill. The label layer is firmly attached to the packaging box by the adhesive layer. However, due to the low tensile strength of the label layer, it is difficult to tear off in one go, causing difficulties in removal. Based on the above problems, the applicant provides a new waybill production and printing process that effectively solves these issues. Summary of the Invention

[0003] The technical solution adopted by the present invention to solve the above problems is: to provide a printing process method for express delivery waybills, including the following steps:

[0004] S1: The support net is output from the middle by the first conveyor line, and the hollow rubber layer is output from the second and third conveyor lines respectively above and below the support net. The hollow rubber layer and the support net are bonded together by hot press rollers.

[0005] S2: Cut the single layer of the express delivery face into shape, attach it to the hollow groove of the hollow rubber layer, and place it on the support net;

[0006] S3: Insert glue into the hollow groove on the lower side of the support net;

[0007] S4: The release layer with raised texture on one side is conveyed by the fifth conveyor line, and the raised texture is adapted to fit the lower side of the hollow groove on the lower side of the support net.

[0008] S5: Send the product obtained in S4 to the printing equipment to print the initial express information on the express waybill.

[0009] S6: After printing, perform roll wrapping and sealing.

[0010] A further preferred embodiment: After S4 is completed, S4.1 uses a set of pressure rollers to press the product.

[0011] A further preferred embodiment: After S5 is completed,

[0012] S5.1: Use a thermal cutting tool to cut off the adjacent single layer of the express delivery surface. The cutting position is at the middle of the horizontal frame, so as to separate the hollow rubber layer from the support mesh.

[0013] S5.2 uses a toothed cutting blade to cut the release layer at the cutting position in S5.1 to form a tear line.

[0014] Further preferred method: After S5.2 is completed, a cutting blade is used to make a longitudinal cut at the middle of the longitudinal frame of the hollow rubber layer, forming a sheet surrounded by the hollow rubber layer.

[0015] A further preferred embodiment: the hollow rubber layer is provided with multiple sets of hollow grooves in the transverse direction.

[0016] A further preferred embodiment: the support mesh is pre-sprayed / coated with adhesive before discharge.

[0017] A further preferred embodiment: the top surface of the express delivery waybill is flush with the end surface of the hollow rubber layer.

[0018] A further preferred embodiment: the hollow rubber layer is made of magnetic rubber.

[0019] A further preferred embodiment is that the support mesh is woven in an oblique cross pattern.

[0020] In a further preferred embodiment, in S3, the support mesh is coated with adhesive at the location of adjacent longitudinal frames.

[0021] Compared with the prior art, the present invention has the following advantages and effects: This process can be carried out in an integrated production line. The express delivery label obtained by this process has a high-strength tensile support mesh fused to a double-layer hollow rubber film layer, which makes the label have higher tensile strength and is not easy to tear.

Detailed Implementation

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0031] See Figures 1-4 This embodiment describes a printing process for express delivery waybills, specifically involving a waybill that can be quickly torn off from the packaging box after use. The structure of the waybill includes the following steps:

[0032] S1: The support net 11 is output from the middle by the first conveying line 1, and the hollow rubber layer is output from the second conveying line 2 and the third conveying line 3 respectively above and below the support net 11. The hollow rubber layer and the support net 11 are bonded together by the hot press roller 102.

[0033] S2: Cut the single layer 41 of the express delivery face into shape, attach it to the hollow groove of the hollow rubber layer, and place it on the support net 11;

[0034] S3: Insert glue into the hollow groove on the lower side of the support mesh 11;

[0035] S4: The release layer 51 with a raised texture is conveyed by the fifth conveyor line 5, and the raised texture is adapted to fit the lower side of the hollow groove on the lower side of the support net 11.

[0036] S5: The product obtained in S4 is sent to the printing device 8 to print the initial express information on the express waybill.

[0037] S6: After printing, perform roll wrapping and sealing.

[0038] For detailed procedures, please refer to [link / document / documentation]. Figure 1 The express delivery waybill produced by this process has a high-strength tensile support net 11 fused to a double-layered hollow rubber film 231, making the waybill stronger and less prone to tearing. Furthermore, after being attached to the express box, it is easy to peel off the entire waybill layer, reducing the likelihood of parts of the waybill remaining on the box during the tearing process. In this embodiment, the support net 11 is constructed with a diagonal cross-woven structure. This diagonal cross-woven structure allows the express delivery waybill layer 41 to be torn off starting from the corner, making it easy to tear with one hand. Simultaneously, the warp and weft arrangement of the support net 11 provides good support and traction to the waybill during the tearing process, making it easier to tear off the waybill completely and further reducing the possibility of localized breakage. In special cases where the waybill is attached to the wrong position and needs to be reattached, it can be completely torn off and re-adhesive applied for adjustment in different positions.

[0039] The production line used in the above process specifically includes a frame 100. The frame 100 is equipped with multiple sets of conveyor lines, which, through a drive device, respectively convey a support net 11, a hollow rubber film 231 layer, a single-layer express surface 41, and a release layer 51. The conveyor lines include a first conveyor line 1, a second conveyor line 2, a third conveyor line 3, a fourth conveyor line 4, and a fifth conveyor line 5. The support net 11 is output from the center via the first conveyor line 1. The two sets of hollow rubber film 231 layers are output above and below the support net 11 via the second conveyor line 2 and the third conveyor line 3, respectively. The single-layer express surface 41 and the release layer 51 are... The output is not through the fourth and fifth feeding lines 5. The second feeding line 2 and the third feeding line 3 are equipped with hot press rollers 102 for clamping and fusing the two sets of hollow rubber film 231 layers with the warp and weft threads of the support net 11. The fourth feeding line 4 is equipped with a cutting component 6 for cutting the express delivery sheet 41 into a square sheet that matches the grid of the support net 11. The frame 100 is also equipped with an adhesive application component 7 for applying adhesive after the square sheet is placed in. The rear end of the frame 100 is equipped with a printing device 8 for printing the initial information of the express delivery sheet after the adhesive is applied and bonded to the release layer 51.

[0040] The specific structure of the cutting component 6 can be found in [reference needed]. Figure 8 As shown, it includes a fixed plate 61, a cutting blade 62, a cutting groove 63, a cylinder 64, an air pump 65, and a solenoid valve 66. The fixed plate 61 is fixed to the frame 100. The air pump 65 is fixed above the fixed plate 61. The solenoid valve 66 and the cylinder 64 are fixed below the fixed plate 61 and connected to the air pump 65 via an air pipe 67. The cutting groove 63 is fixed inside the frame 100 and positioned below the cylinder 64. The cutting blade 62 is fixed to the cylinder 64 and is driven by the cylinder 64 to slide up and down within its cutting groove 63. (See also...) Figure 9The cutting groove 63 is provided with a first guide groove 631 and a second guide groove 632. The express delivery single layer 41 passes through the first guide groove 631. The hollow rubber film 231, which is compositely bonded by the hot pressing roller 102, and the support net 11 pass through the second guide groove 632 provided below. The cutting component 6 cuts the appropriate single layer for attachment to the support net 11. This structure is designed to meet the production requirements of the bonding process. Compared with the traditional method of directly attaching the single layer to the upper side, it takes into account the height gap between the hollow rubber film layer itself and the support net 11, so that the bonding can be better and the integrity can be guaranteed. At the same time, it facilitates better contact and bonding between the single layer and the support net 11.

[0041] In this embodiment, after S4, S4.1 uses a pressing roller group 103 to press the product. Specifically, the frame 100 is also provided with a pressing roller group 103. The two sets of rollers 101 of the pressing roller group 103 are rotatably arranged on the frame 100 and are adapted to fit and adhere to the single layer 41 of the express delivery surface 41 and the release layer 51 below it for pressing the single layer 41 of the express delivery surface 41, the hollow rubber film 231 layer, the conveying support net 11 and the release layer 51.

[0042] In this embodiment, after S5 ends,

[0043] S5.1: Use a thermal cutting blade to cut off the adjacent single layer 41 of the express delivery surface. The cutting position is in the middle of the horizontal frame, so that the hollow rubber layer can be heat-melted to form a thinner adhesive film.

[0044] S5.2 The toothed cutting blade 93 is used to cut the release layer 51 at the cutting position in S5.1 to form a tear line.

[0045] After S5.2 is completed, a cutting blade is used to make a longitudinal cut at the middle of the longitudinal frame of the hollow rubber layer, forming a sheet surrounded by the hollow rubber layer.

[0046] In this embodiment, the hollow rubber layer is provided with multiple sets of hollow grooves in the transverse direction, so that multiple sets of strip-shaped hollow rubber film 231 layers are arranged adjacently in the transverse direction, thereby increasing the number of products formed in a single production line process and improving production efficiency.

[0047] For details of the above process, please refer to Figure 10The frame 100 is also equipped with cutting blades, including a hot-pressing blade 92 for hot-pressing two sets of hollow rubber film 231 layers at the boundary of adjacent sheets to form a film that is easy to tear, and a toothed cutting blade 93 for forming intermittent tear lines at the boundary of adjacent sheets (and cutting the warp and weft threads of the support net 11 of the front and rear adjacent sheets). The hot-pressing blade 92 and the toothed cutting blade 93 are both fixed to the matching positions of the fixing frame 91 by two sets of blades arranged vertically. The fixing frame 91 is fixed to the frame 100 and its driving device drives the lower fixing frame 91 to slide relative to the upper fixing frame 91. Since there are multiple sets of strip-shaped hollow rubber film 231 layers arranged laterally, the rear end of the frame 100 is also equipped with a strip cutting blade group. The strip cutting blade group is composed of several ring cutting blades 96. For details, please refer to [link to relevant documentation]. Figure 11 As shown, the annular cutting blade 96 is mounted on the adapter roller 101 and driven to rotate by its driving device to cut adjacent sheets into strips, which are then wound into shape by the rear winding shaft. The cutting blade assembly cuts adjacent transversely arranged hollow rubber film 231 layers along the middle of the longitudinal frame strip, forming... Figure 11 The sheet is surrounded by a U-shaped rubber film. The first glue storage box 71 has auxiliary rollers on both sides of its glue outlet, which are adapted to the longitudinal frame strips of the U-shaped hollow rubber film 231. The brushes 72 are positioned at intervals between adjacent frame strips. The shape of the roller 101 can be found in [reference needed]. Figure 6 As shown, the rotation of roller 101 prevents the two sides of the hollow rubber mold layer from being coated with glue, so that the release layer 51 on both sides of the face sheet produced by this process has a certain separation edge, which makes it easy to tear off the face sheet layer 41. At the same time, the hollow rubber film 231 layer itself has a slight adhesiveness, which also makes it easy to attach the edge and not easy to peel off the edge. In addition, during the tearing process, it is also easy to peel off the separated edge and find the peeling start position.

[0048] The support mesh 11 is pre-sprayed / coated with adhesive before discharge; see details below. Figure 7 As shown, the first feeding line 1 is also equipped with a second glue storage box 71 for adapting the front support net 11 to be brushed with glue, and a second roller group to press the support net 11 to facilitate the removal of excess glue, so that the cut sheet can be attached to the support net 11 for subsequent processes.

[0049] The top surface of the express delivery waybill is flush with the top surface of the hollow rubber layer, ensuring a compact overall structure and preventing edge warping. The hollow rubber layer is made of magnetic rubber, facilitating future expansion. Later, in automated labeling lines, a robotic arm with magnetic adsorption function can be used to peel and attach the waybill. The support mesh 11 is constructed with a diagonal cross-woven structure. In this embodiment, the diagonal cross-woven support mesh 11 allows the express delivery waybill layer 41 to be torn off starting from the corner, making it easy to tear with one hand. Simultaneously, the warp and weft arrangement of the support mesh 11 provides good support for the waybill during the tearing process. Traction allows for easier and more complete tearing of the sheet, further reducing the possibility of partial breakage. In special cases where the sheet is attached to the wrong position and needs to be re-attached, it can be completely torn off and re-glued for adjustment in different positions. In S3, the support net 11 applies glue to the space between adjacent longitudinal frames. The first glue storage box 71 has auxiliary rollers on both sides of the glue outlet, which are adapted to be positioned at the longitudinal frame strips of the hollow rubber film 231 layer. The brush 72 is positioned at the intervals between adjacent frame strips. For the specific shape of the roller 101, please refer to [reference needed]. Figure 6 As shown, the rotation of roller 101 prevents the two sides of the hollow rubber film layer from being coated with glue, resulting in a certain separation edge of the release layer 51 on both sides of the face sheet produced by this process. This facilitates the tearing off of the face sheet layer 41. At the same time, the hollow rubber film 231 layer itself has a slight adhesiveness, which also facilitates the adhesion of the edge and prevents it from peeling off. During the tearing process, it is also convenient to peel off the separated edge and find the peeling start position. The side of the hot press knife 92 is sharpened so that the film is separated on the side, which facilitates the side tearing.

[0050] The above description is merely illustrative of the invention. Those skilled in the art can make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined by the claims, all of which should fall within the protection scope of this invention.
