TECHNICAL FIELD

[0001] The application relates to the technical field of gilding equipment, in particular to a label efficient gilding and die cutting all-in-one machine. BACKGROUND

[0002] The gilding and die cutting all-in-one machine is a printing machine integrating gilding and die cutting functions. The all-in-one machine can complete the gilding and die cutting two process flows on one machine, improving the production efficiency and processing quality.

[0003] The gilding and die cutting all-in-one machine is usually composed of a gilding module, a die cutting module, gilding paper or gilding film, a pressure adjusting device, a temperature adjusting device, a control system and the like. In the production process, the gilding and die cutting all-in-one machine first pastes the gilding paper or gilding film on the printing material, and then cooperates the gilding module and the die cutting module to die cut the gilding material and the printing material into the required shape and size.

[0004] Compared with the traditional gilding and die cutting equipment, the gilding and die cutting all-in-one machine has higher production efficiency and processing precision, and can greatly improve the quality and added value of the printed matter. At the same time, due to the compact structure and simple operation of the gilding and die cutting all-in-one machine, it has also been widely applied.

[0005] However, the current gilding and die cutting all-in-one machine has problems such as uneven gilding and unfirm gilding foil adhesion when processing labels due to static electricity on the labels, so that the quality of gilding cannot be guaranteed. SUMMARY

[0006] In order to improve the quality of label gilding, the application provides a gilding and die cutting all-in-one machine.

[0007] The gilding and die cutting all-in-one machine provided by the application adopts the following technical scheme:

[0008] A label gilding and die cutting all-in-one machine, comprising a unwinding device, the unwinding device comprises a unwinding platform and a flattening assembly, the bottom of the unwinding platform is rotatably connected with a winding roller for winding the label, one end of the unwinding platform away from the winding roller is provided with a conveying assembly for providing a pulling force to the label, the flattening assembly comprises a extrusion plate arranged on the unwinding platform, the bottom of the extrusion plate is detachably connected with a cleaning piece, and the cleaning piece comprises a cleaning pad abutting against the surface of the label.

[0009] By adopting the above technical scheme, the conveying assembly pulls the label to unwind from the winding roller, and when the label passes below the extrusion plate, the cleaning pad can clean the dust on the surface of the label, thereby reducing static electricity caused by dust and impurities and improving the process quality of label gilding.

[0011] By adopting the above technical scheme, when the cleaning pad is too dirty or damaged, the bolt is screwed to dismount the cleaning piece from the bottom of the extrusion plate, and a new cleaning piece is replaced, the original cleaning piece is cleaned or repaired, and the regular replacement of the cleaning piece can improve the work efficiency and processing quality.

[0012] As preferred, the two sides of the unwinding platform are fixedly connected with support columns, the support columns are provided with sliding grooves, one of the sliding grooves is rotatably connected with a threaded screw rod, the other sliding groove is fixedly connected with a limiting column, the two ends of the extrusion plate are respectively inserted into the corresponding sliding grooves, the threaded screw rod passes through one end of the extrusion plate and is threadedly connected with the extrusion plate, the limiting column penetrates the other end of the extrusion plate, and one end of the threaded screw rod penetrating the sliding groove is connected with a driving source.

[0013] By adopting the above technical scheme, the driving source drives the threaded screw rod to rotate, one end of the extrusion plate is limited by the limiting column, so that the extrusion plate can move vertically on the threaded screw rod, thereby adjusting the distance between the extrusion plate and the surface of the winding platform, so that the cleaning pad contacts the surface of the label to remove the dust on the surface of the label, and the amount of static electricity on the surface of the label is reduced.

[0014] As preferred, the conveying assembly comprises a first roller and a second roller rotatably connected to the unwinding platform, the second roller is located directly below the first roller, and the outer wall of the first roller is attached to the outer wall of the second roller.

[0015] By adopting the above technical scheme, when the label passes between the first roller and the second roller, the first roller and the second roller rotate to provide a traction force to the label to pull the label to move away from the unwinding platform. At the same time, the first roller contacts the upper surface of the label, and the second roller contacts the lower surface of the label, so that the first roller and the second roller not only provide a traction force to the label, but also flatten the label, and the contact between the first roller and the upper surface of the label can further clean the label, thereby reducing the possibility of static electricity on the surface of the label.

[0016] As preferred, the gilding device comprises a gilding die-cutting machine and a winding assembly, the winding assembly comprises a fixed frame, the bottom of the fixed frame is rotatably connected with a first winding roller and a second winding roller.

[0019] By adopting the technical scheme, the limiting device can be adjusted according to the width of the label, so as to adapt to labels of different sizes, and the movement direction of the label is limited, thereby reducing the displacement of the label on the first winding roller and the second winding roller.

[0020] Preferably, a slack assembly is arranged between the unwinding device and the gilding device, the slack assembly comprises two standing plates, a rotating roller is rotatably connected between the two standing plates, a plasma air blower is fixedly connected to the outer wall of the rotating roller, and the blowing port of the plasma air blower is aligned with the surface of the label.

[0022] Preferably, a supporting rod is connected between the two standing plates.

[0023] By adopting the technical scheme, when the winding assembly fails, the label between the two standing plates gradually grows, and the label that falls too long is easy to come into contact with the ground, so that the label is covered with dust. By winding the label on the supporting rod, the label is not easy to fall to the ground, thereby ensuring the cleanliness of the label.

[0024] Preferably, two parallel moving grooves are formed in the two standing plates along the vertical direction, the end portion of the supporting rod is slidably arranged in the moving grooves, and the two ends of the supporting rod that pass through the standing plates are respectively threadedly connected with bolts.

[0025] By adopting the technical scheme, the supporting rod can vertically slide between the two standing plates, so as to adjust the height of the supporting rod, and thus the label accommodated between the two standing plates is longer.

[0026] In summary, the present application has at least one of the following beneficial technical effects:

[0027] 1. The conveying assembly pulls the label to unwind from the winding roller, and when the label passes below the pressing plate, the cleaning pad can clean the dust on the surface of the label, thereby reducing static electricity caused by dust and impurities, and improving the process quality of label gilding;

[0028] 2. When the label passes between the first roller and the second roller, the first roller and the second roller rotate to provide a traction force to the label to pull the label to move in a direction away from the unwinding platform. At the same time, the first roller is in contact with the upper surface of the label, and the second roller is in contact with the lower surface of the label. The first roller and the second roller provide a traction force to the label while flattening the label, and the contact between the first roller and the upper surface of the label can further clean the label to reduce the possibility of static electricity on the surface of the label.

[0029] 3. After the winding assembly fails, the label between the two standing plates gradually grows, and the overhanging label is too long to contact the ground, which makes the label full of dust. The label is wound on the support rod, so that the label is not easy to fall to the ground, and the neatness of the label is ensured. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0036] The following will be described in detail in combination with the accompanying drawings Figures 1-5 The present application will be further described in detail.

[0037] This application discloses an integrated label hot stamping and die-cutting machine.

[0038] A label hot stamping and die-cutting integrated machine, as described in the reference Figure 1 It includes an unwinding device 1 and a hot stamping device 2. The unwinding device 1 includes an unwinding platform 11 and a leveling component 12 disposed on the unwinding platform 11. A take-up roller 14 is rotatably connected to the bottom of the unwinding platform 11. The take-up roller 14 is wound with the label to be processed. One end of the unwinding platform 11 is connected to a conveying component 13 for pulling the label onto the unwinding platform 11.

[0039] Reference Figure 2 Support columns 15 are fixedly connected to both sides of the unwinding platform 11. A sliding groove 151 is provided on the opposite side of the two support columns 15. A threaded screw 16 is rotatably connected in one sliding groove 151, and a limit post 17 is fixedly connected in the other sliding groove 151. A drive source 18 for driving the threaded screw 16 to rotate is fixed on the top of the support column 15. The drive source 18 is a servo motor. The output end of the drive source 18 is inserted into the sliding groove 151 and fixedly connected to the threaded screw 16.

[0040] Reference Figure 2 The leveling assembly 12 includes an extrusion plate 121 slidably disposed in a sliding groove 151. Both ends of the extrusion plate 121 are respectively inserted into the corresponding sliding grooves 151. A threaded screw 16 passes through one end of the extrusion plate 121 and is threadedly connected to the extrusion plate 121. A limiting post 17 passes through the other end of the extrusion plate 121.

[0041] The drive source 18 drives the threaded screw 16 to rotate. One end of the extrusion plate 121 is limited by the limiting post 17, which allows the extrusion plate 121 to move vertically on the threaded screw. This adjusts the distance between the extrusion plate 121 and the winding platform, so that the extrusion plate 121 contacts the surface of the label. When the label moves to the winding platform and passes under the extrusion plate 121, the extrusion plate 121 can flatten the label, reducing the occurrence of wrinkles and thus improving the quality of the hot stamping.

[0042] Reference Figure 2 and Figure 3 The bottom of the extrusion plate 121 is detachably connected to a cleaning component. Two cleaning components are provided, one at each end of the unwinding platform 11. The cleaning component includes a fixing plate 122 and a cleaning pad 124 fixedly connected to the lower part of the fixing plate 122. Several plug-in plates 123 are fixedly connected to the side of the fixing plate 122 facing away from the cleaning pad 124. The bottom of the extrusion plate 121 has a slot for the plug-in plates 123 to be inserted. Bolts that are threaded into the slots are connected to the side wall of the extrusion plate 121.

[0043] The plug-in plate 123 is inserted into the corresponding card slot, and the bolt is screwed so that one end of the bolt enters the card slot and abuts against the surface of the plug-in plate 123, thereby fixing the fixed plate 122 below the extrusion plate 121. When the label passes below the extrusion plate 121, the cleaning pad 124 can clean the dust on the surface of the label, thereby reducing static electricity caused by dust and impurities and improving the process quality of label gilding. When the cleaning pad 124 adheres too much dust or the cleaning pad 124 is damaged, the bolt is unscrewed to detach the cleaning piece from the bottom of the extrusion plate 121, and a new cleaning piece is replaced. The original cleaning piece is cleaned or repaired, and the cleaning piece is replaced regularly to improve work efficiency and processing quality. The two cleaning pieces can enhance the flatness of the label between the two cleaning pieces.

[0044] With reference to Figure 2 and Figure 4 The conveying assembly 13 comprises a first roller 131 and a second roller 132 rotatably connected to the unwinding platform 11 away from the winding roller 14. The second roller 132 is located directly below the first roller 131, and the outer wall of the first roller 131 is attached to the outer wall of the second roller 132. The second roller 132 is rotatably connected to the unwinding platform 11, and the third roller 133 is rotatably connected to the unwinding platform 11. The third roller 133 is parallel to the third roller 133, and the adjusting roller 134 is arranged between the third roller 133 and the unwinding platform 11.

[0045] After the label is flattened and cleaned by the flattening assembly 12, it passes through the adjusting roller 134 and is wound to the bottom of the third roller 133, and then enters the gilding device 2 through the first roller 131 and the second roller 132. The adjusting roller 134 supports the label, and the third roller 133 is curved, which can straighten the label. The third roller 133 also provides power for the transmission of the label. When the label passes between the first roller 131 and the second roller 132, the first roller 131 and the second roller 132 rotate to provide traction to the label, pulling the label towards the direction away from the unwinding platform 11. At the same time, the first roller 131 contacts the upper surface of the label, and the second roller 132 contacts the lower surface of the label. The first roller 131 and the second roller 132 flatten the label while providing traction to the label. The first roller 131 contacting the upper surface of the label can further clean the label, reducing the possibility of static electricity on the surface of the label.

[0046] With reference to Figure 2 and Figure 5The gilding device 2 comprises a gilding die cutting machine 21 and a winding assembly 22. The winding assembly 22 comprises a fixing frame, the bottom of the fixing frame is rotationally connected with a first winding roller 221 and a second winding roller 222, a limiting roller 223 is arranged between the first winding roller 221 and the second winding roller 222, the diameter of the limiting roller 223 is smaller than that of the first winding roller 221 and the second winding roller 222, two limiters 224 are slidably arranged on the limiting roller 223, the limiters 224 are annular limiting blocks, and a locking rod is threadedly connected with the limiting blocks.

[0047] With reference to Figure 5 The label is arranged in an S-shaped curve between the first winding roller 221 and the second winding roller 222. The first winding roller 221 and the second winding roller 222 provide a traction force to the label when rotating, so that the label moves towards the gilding die cutting machine 21. The limiting roller 223 limits the moving direction of the label. By screwing the locking rod, the limiting blocks are slid on the limiting roller 223, and the positions of the two limiting blocks are moved, so that the distance between the two limiting blocks is sufficient for the label to pass. The limiters 224 can be adjusted according to the width of the label, so as to adapt to labels of different sizes, and limit the moving direction of the label, thereby reducing the displacement of the label on the first winding roller 221 and the second winding roller 222.

[0048] With reference to Figure 2 and Figure 5 A slack assembly 3 is arranged between the unwinding device 1 and the gilding device 2. The label falls between the two upright plates 31 of the slack assembly 3. The falling label can eliminate the tension of the label itself, so that the surface of the label is smoother and more flat, and problems such as cracks and deformation are avoided. When the label is subjected to a traction force, stress will be generated inside the label. If the stress is too large, the object may be broken or deformed. The falling label can prevent this from happening, eliminate the stress inside the falling label, and keep it in a stable state.

[0049] When the conveying assembly 13 fails, the end of the conveying assembly 13 no longer unwinds the label, but the winding assembly 22 continues to wind the label. The traction force applied by the winding assembly 22 makes the label straighten and is prone to breakage. By setting the label in a slack state, the winding assembly 22 will first straighten the slack label, thereby providing time for the construction personnel to shut down the equipment, and reducing the possibility of label breakage.

[0050] With reference to Figure 2 and Figure 5The two standing plates 31 are provided with two parallel moving grooves 32 in the vertical direction, the supporting rods 33 are slidably arranged in the moving grooves 32, and the two ends of the supporting rods 33 are respectively threadedly connected with bolts. When the winding assembly 22 fails, the labels between the two standing plates 31 gradually grow, and the labels are too long to be in contact with the ground, so that the labels are covered with dust. The labels are arranged on the supporting rods 33, so that the labels are not easy to fall to the ground, and the cleanliness of the labels is ensured. Meanwhile, the supporting rods 33 can vertically slide between the two standing plates 31, so that the height of the supporting rods 33 is adjusted, and the labels accommodated between the two standing plates 31 are longer.

[0051] Referring to Figure 2 and Figure 5 The two standing plates 31 are provided with two parallel moving grooves 32 in the vertical direction, the supporting rods 33 are slidably arranged in the moving grooves 32, and the two ends of the supporting rods 33 are respectively threadedly connected with bolts. When the winding assembly 22 fails, the labels between the two standing plates 31 gradually grow, and the labels are too long to be in contact with the ground, so that the labels are covered with dust. The labels are arranged on the supporting rods 33, so that the labels are not easy to fall to the ground, and the cleanliness of the labels is ensured. Meanwhile, the supporting rods 33 can vertically slide between the two standing plates 31, so that the height of the supporting rods 33 is adjusted, and the labels accommodated between the two standing plates 31 are longer.

[0052] The plasma fan 35 can ionize air to generate a large number of positive and negative ions, and then blow the ions to the surface of the object to neutralize static electricity, so as to avoid the accumulation of static electricity to cause adverse effects on production and product quality.

[0053] The implementation principle of the label gold stamping and die cutting all-in-one machine is that the conveying assembly 13 provides a traction force for the labels, so that the labels move on the unwinding platform 11, the leveling assembly 12 levels the labels and cleans the dust on the surface of the labels, so as to reduce the static electricity on the surface of the labels. The first roller 131 and the second roller 132 provide a traction force for the labels while flattening the labels, and the first roller 131 in contact with the upper surface of the labels can further clean the labels, thereby reducing the possibility of static electricity on the surface of the labels.

[0054] When the labels enter between the two standing plates 31, the labels become in a hanging state and are arranged on the supporting rods 33, the plasma fan 35 eliminates the static electricity on the surface of the labels, and the winding assembly 22 flattens and straightens the labels and conveys the labels to the gold stamping and die cutting machine 21 for gold stamping and die cutting processing.

[0055] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, so that: any equivalent changes made on the structure, shape and principle of the present application shall be covered within the protection scope of the present application.
