Abstract
Description
Technical Field
[0001] The invention relates to the technical field of laminating machines, and in particular to an automatic laminating machine for packaging boxes. Background Art
[0002] In order to prevent the packaging box from being scratched during transportation, a protective film is usually put on the outside of the packaging box. The protective film commonly used for packaging boxes is heat shrink film. This heat shrink film is heated after being wrapped in the packaging box, and then it can be wrapped around the outside of the packaging box to play a protective role.
[0003] Heat shrink film is a type of shrink film. Heat shrink film is used for the sale and transportation of various products. Its main function is to stabilize, cover and protect the products. Now, since the heat shrink film on the outside of the packaging box is in the laminating machine, hot air is used to heat and tighten the heat shrink film on the outside of the packaging box.
[0004] However, when the current packaging box laminating machine uses hot air to heat the packaging box, the packaging box is large in size, so the hot air cannot evenly heat the outside of the packaging box, which will cause some heat shrink film to fail to adhere to the packaging box. This not only affects the appearance, but also causes the heat shrink film on the outside of the packaging box to fall off during transportation. Summary of the invention
[0005] The purpose of the present invention is to solve the problems existing in the prior art and to propose an automatic film laminating machine for packaging boxes.
[0006] In order to achieve the above object, the present invention adopts the following technical solutions: 7. The swiftly and minutely adjusting device for a wood-planer working table as claimed in claim 1, wherein said linking rod and said adjusting base are pivotally connected to each other with a bolt, and said bolt has a round shank to contact with said linking rod. said linking rod has a round shank to contact with said linking rod.
[0007] In order to better achieve the above-mentioned purpose, the present invention adopts a further technical solution: the threads opened at both ends of the first screw and the second screw are opposite, the outer sides of the two ends of the first screw are fixedly connected to the limiting plates, the moving block is inside the first moving groove and the second moving groove, and the size of the moving block is adapted to the first moving groove and the second moving groove, and the first moving groove at one end of the workbench is rotatably connected to the second bevel gear, and the first bevel gear is meshed with the second bevel gear.
[0008] In order to better achieve the above-mentioned purpose, the present invention adopts a further technical solution: a transmission mechanism is arranged at the front part of the workbench, and the transmission mechanism includes two groups of rotating columns, and one group of the rotating columns passes through the workbench and is fixedly connected to one end of the second screw, and the other group of the rotating columns passes through the workbench and is fixedly connected to the second bevel gear, a transmission belt is sleeved on the outside of the rotating column, a protective shell is arranged on the outside of the transmission belt, and the protective shell is fixedly connected to the workbench, a motor is fixedly connected to one end of the protective shell, and the output shaft of the motor passes through the protective shell and is fixedly connected to one group of rotating columns, and an air cooler is arranged at the front part of the bracket, and the air cooler is fixedly connected to the bracket.
[0009] The advantages of the present invention are: 1. The present invention realizes the function of placing the packaging box with the heat shrink film on the placement groove through the structural design of the fixing mechanism, and turning on the motor and the automatic telescopic rod. At this time, the motor will drive the first screw and the second screw to rotate through the transmission mechanism, and will drive the moving blocks and the heating plate at both ends of the first screw and the second screw to be close to the outside of the packaging box, and the automatic telescopic rod will also move the pressing plate downward to the top of the packaging box, and the heating plate, the pressing plate and the bottom of the placement groove will heat the heat shrink film, so that all the heat shrink film on the outside of the packaging box is heated, which solves the problem that when the current packaging box laminating machine uses hot air to heat the packaging box, the packaging box is large in size, so the hot air cannot evenly heat the outside of the packaging box, which will cause part of the heat shrink film to fail to be close to the packaging box, which not only affects the appearance, but also causes the heat shrink film on the outside of the packaging box to fall off during transportation.
[0010] 2. The present invention realizes the function of sleeved transmission belt on the outside of the rotating column through the structural design of the transmission mechanism. In this way, only one set of motors and one set of rotating columns need to rotate to drive the transmission belt and the other set of rotating columns to rotate. In this way, the motor can control the first screw and the second screw to rotate at the same time. The protective shell can prevent the transmission belt sleeved on the outside of the rotating column from falling off, and can prevent outsiders from touching the transmission belt when the transmission belt rotates. This solves the problem that the four sets of heating plates need to be moved to the outside of the packaging box for heating the heat shrink film on the outside of the packaging box, so the two sets of first screws and the second screw need to rotate. In order to reduce the installation of the motor and reduce the production cost, the rotation of the first screw and the second screw are respectively controlled by two sets of rotating columns.

DETAILED DESCRIPTION
[0013] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0014] See also Figure 1 - Figure 4As shown, an automatic laminating machine for packaging boxes comprises a workbench 1, wherein the four corners of the bottom end of the workbench 1 are fixedly connected to supporting legs 2, a bracket 3 is fixedly connected to the rear of the workbench 1, an automatic telescopic rod 4 is fixedly connected to the bottom end of the bracket 3, a pressing plate 5 is fixedly connected to the bottom end of the automatic telescopic rod 4, a placement slot 6 is provided at the top of the workbench 1, a fixing mechanism is provided at the top of the workbench 1, the fixing mechanism comprises two groups of first moving slots 7, and the two groups of first moving slots 7 are provided at both ends of the workbench 1, a second moving slot 8 is provided at the front and rear of the top end of the workbench 1, a first screw rod 9 is provided inside the workbench 1, both ends of the first screw rod 9 pass through the first moving slot 7 and are fixedly connected to the two groups of first bevel gears 15, the first bevel gear 15 is rotatably connected to one end of the first moving slot 7, a second screw rod 10 is provided inside the workbench 1, both ends of the second screw rod 10 pass through the second moving slot 8 and the second One end of the movable groove 8 is rotatably connected, and the outer sides of the two ends of the first screw 9 and the second screw 10 are threadedly connected with a movable block 11, the top of the movable block 11 is fixedly connected with a heating plate 12, and the top of the placement groove 6 is provided with a packaging box 13; through the structural design of the fixing mechanism, when the packaging box 13 with a heat shrink film is placed on the placement groove 6, the motor 20 and the automatic telescopic rod 4 are turned on, and at this time, the motor 20 will drive the first screw 9 and the second screw 10 to rotate through the transmission mechanism, and will drive the movable blocks 11 and the heating plate 12 at both ends of the first screw 9 and the second screw 10 to be close to the outside of the packaging box 13, and the automatic telescopic rod 4 will also move the pressing plate 5 downward to the top of the packaging box 13, and the heating plate 12, the pressing plate 5 and the bottom of the placement groove 6 will heat the heat shrink film, so that all the heat shrink films on the outside of the packaging box 13 are heated.
[0015] like Figure 4 As shown, the threads at both ends of the first screw 9 and the second screw 10 are opposite, and the outer sides of the two ends of the first screw 9 are fixedly connected to the limiting plates 14. The threads at both ends of the first screw 9 and the second screw 10 are opposite, so when they rotate, the moving blocks 11 and the heating plates 12 at both ends will move toward each other, thereby fitting to the outside of the packaging box 13 to heat and shrink the heat shrink film on the outside of the packaging box 13.
[0016] like Figure 1 As shown, the moving block 11 is inside the first moving groove 7 and the second moving groove 8, and the size of the moving block 11 is adapted to the first moving groove 7 and the second moving groove 8. The rotation of the first screw 9 or the second screw 10 will cause the moving block 11 to have the same tendency to rotate. Since the size of the moving block 11 is adapted to the first moving groove 7 and the second moving groove 8, the tendency of the moving block 11 to rotate will be hindered. Because of the characteristics of the threaded connection between the moving block 11 and the first screw 9 and the second screw 10, the moving block 11 can move as the first screw 9 and the second screw 10 rotate.
[0017] like Figure 4As shown, the first movable groove 7 at one end of the workbench 1 is rotatably connected to the inside thereof with a second bevel gear 16, and the first bevel gear 15 is meshed with the second bevel gear 16. Since the transmission belt 18 is sleeved on the outside of the two sets of rotating columns 17 in the transmission mechanism, the two sets of rotating columns 17 need to be placed in parallel, and the two sets of screws are cross-arranged, the rotating column 17 cannot be arranged to be directly connected to the rotating column 17. The first bevel gear 15 fixedly connected to one end of the first screw 9 is meshed with the second bevel gear 16. At this time, the rotation of the second bevel gear 16 will also drive the first bevel gear 15 and the rotating column 17 to rotate, and at this time, the rotating column 17 fixedly connected to the second bevel gear 16 is parallel to the rotating column 17 connected to the second screw 10.
[0018] like Figure 2 As shown, a transmission mechanism is provided at the front of the workbench 1, and the transmission mechanism includes two groups of rotating columns 17, and one group of rotating columns 17 passes through the workbench 1 and is fixedly connected to one end of the second screw 1, and the other group of rotating columns 17 passes through the workbench 1 and is fixedly connected to the second bevel gear 16, and a transmission belt 18 is sleeved on the outer side of the rotating columns 17, and a protective shell 19 is provided on the outer side of the transmission belt 18, and the protective shell 19 is fixedly connected to the workbench 1, and a motor 20 is fixedly connected to one end of the protective shell 19, and the output shaft of the motor 20 passes through the protective shell 19 and is fixedly connected to one group of rotating columns 17. Since the heat shrink film on the outside of the packaging box 13 needs to be heated, all four groups of heating plates 12 need to be moved to the outside of the packaging box 13 side, so both the first screw 9 and the second screw 10 need to rotate. In order to reduce the installation of the motor 20 and reduce the production cost, the rotation of the first screw 9 and the second screw 10 are respectively controlled by two sets of rotating columns 17, and the transmission belt 18 is sleeved on the outside of the rotating column 17. In this way, only one set of motors 20 and one set of rotating columns 17 are needed to rotate, so as to drive the transmission belt 18 and the other set of rotating columns 17 to rotate. In this way, the motor 20 can control the first screw 9 and the second screw 10 to rotate at the same time, and the protective shell 19 can prevent the transmission belt 18 sleeved on the outside of the rotating column 17 from falling off, and can prevent outsiders from touching the transmission belt 18 when the transmission belt 18 rotates.
[0019] like Figure 1 As shown, a cold air fan 21 is provided at the front of the bracket 3, and the cold air fan 21 is fixedly connected to the bracket 3. After the coating work of the packaging box 13 is completed, the temperature of the outside of the packaging box 13 is relatively high, and the staff cannot touch it directly with their hands. Therefore, the cold air fan 21 needs to be turned on at this time to cool down the heat shrink film on the outside of the packaging box 13 before it can be transported.
[0020] When the present invention is used, when the packaging box 13 with the heat shrink film is placed on the placement slot 6, the motor 20 and the automatic telescopic rod 4 are turned on. The motor 20 drives the two sets of rotating columns 17 to rotate, thereby driving the second screw 10 and the second bevel gear 16 to rotate, and the second bevel gear 16 is meshed with the first bevel gear 15 at one end of the first screw 9, so the second screw 10 will also rotate. At this time, the moving blocks 11 and the heating plate 12 at both ends of the first screw 9 and the second screw 10 are tightly attached to the outside of the packaging box 13, and the automatic telescopic rod 4 will also move the pressing plate 5 downward to the top of the packaging box 13, the heating plate 12, the pressing plate 5 and the bottom of the placement slot 6 will heat the heat shrink film, and the coating work of the packaging box 13 is completed at this time. After the coating work of the packaging box 13 is completed, the temperature of the outside of the packaging box 13 is high, and the staff cannot touch it directly with their hands, so it is necessary to turn on the cold air fan 21 to cool the heat shrink film on the outside of the packaging box 13 before carrying it.
[0021] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
