Description

Technical Field

[0001] This utility model relates to the field of plastic film processing, and in particular to an integrated machine for applying adhesive and printing on plastic film. Background Technology

[0002] In the processing of plastic film, in order to meet the market's demand for diverse decoration and functionality of plastic film, it is often necessary to use an integrated plastic film gluing and printing machine. Existing integrated plastic film gluing and printing machines usually adopt a layout of multiple printing machines set at equal intervals. The material tank of the last printing machine can hold glue, thereby realizing the integrated operation of gluing and printing.

[0003] Because different customers have different requirements for the printing patterns and colors of plastic films, the printing patterns and colors need to be changed frequently during the production process. At the same time, during long-term use, the pigment around the material tank is prone to drying and clumping. The clumped pigment can easily adhere to the plastic film being processed as the printing roller rotates, which will affect the printing quality. Therefore, the material tank needs to be cleaned regularly. However, the material tank in the existing plastic film gluing and printing integrated machine is often placed horizontally and does not have a flipping function. When cleaning the material tank, it can only be done by repeatedly rinsing to let the cleaning wastewater flow out from the overflow hole of the material tank. This is not only inefficient, but also difficult to completely remove the residual pigment and clumps in the material tank, and it is easy to leave cleaning dead corners.

[0004] Therefore, this utility model provides an integrated machine for applying adhesive to plastic film and printing to meet the requirements. Utility Model Content

[0005] The technical problem this utility model aims to solve is to provide an integrated plastic film coating and printing machine. By setting a flipping component, the wastewater and residual pigment from the cleaning process can flow out of the material tank more smoothly. At the same time, it facilitates thorough cleaning of all corners inside the material tank, thereby effectively removing residual pigment and clumps. This design solves the problem that when cleaning a horizontally placed material tank, the cleaning wastewater can only be discharged from the overflow hole of the material tank by repeated rinsing, resulting in low cleaning efficiency and difficulty in thoroughly removing residual pigment and clumps, easily leaving cleaning dead corners.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A plastic film coating and printing integrated machine includes a control cabinet and a printing machine. The printing machine is equipped with a liftable material trough and a rotatable printing roller located above the material trough. The control cabinet is electrically connected to the printing machine. A flipping assembly is used to flip the material trough and is connected to both the printing machine and the material trough. The printing machine includes a base with two symmetrical supports fixed to the top of the base. The material trough and the printing roller are both located between the two supports.

[0008] Optionally, the flipping assembly includes a turntable 1 and a turntable 2 that rotate on the inner sides of the two supports respectively. A connecting block is fixed on the side of the turntable 1 and the turntable 2 that are close to each other. The material trough is slidably connected to the connecting block. A worm gear 1 is fixed on the side of the turntable 2 away from the connecting block. A worm is rotatably provided on one side of one of the supports. The worm gear 1 meshes with the worm gear 1. A handwheel 1 is fixed to one end of the worm gear 1. A connecting shaft is rotatably provided between the two connecting blocks. One end of the connecting shaft passes through the worm gear 1 and is provided with a limiting component for limiting the position of the connecting shaft.

[0009] Optionally, the limiting assembly includes a connecting plate fixed to one side of the worm gear, a worm gear rotatably mounted on one side of the connecting plate, a connecting shaft passing through the connecting plate and fixed to the worm gear, the worm gear meshing with the worm gear, and a handwheel fixed to one end of the worm gear.

[0010] Optionally, a liftable support plate is slidably provided on one side of the connecting block.

[0011] Optionally, the top of the tray is arc-shaped, and when the material trough is flipped, the top of the tray can rise to fit against the bottom surface of the printing roller.

[0012] Optionally, a groove is provided on one side of the connecting block, and the tray slides in the groove.

[0013] Optionally, a support block is fixed at the bottom of the material trough, and a groove is provided on one side of the support block. When the support block and the side of the slide groove are close to each other, the slide groove and the groove are connected, and the pallet can slide into the groove.

[0014] Optionally, insert plates and end plates are sequentially inserted at both ends of the printing roller. The insert plate is located inside the end plate, and a fixing shaft is fixed between the insert plate and the end plate. One end of the fixing shaft is engaged with the bracket.

[0015] Optionally, the printing roller is provided with an abutment groove that abuts against the inner side of the insert plate.

[0016] Optionally, the distance from the outer side of the end plate to the inner side of the bracket is equal to the distance from the outer side of the insert plate to the outer side of the printing roller.

[0017] Compared with the prior art, this utility model has at least the following beneficial effects:

[0018] In the above solution, by setting up a flipping component, the wastewater and residual pigment from the cleaning process can flow out of the material tank more smoothly. At the same time, it is convenient to thoroughly clean all corners inside the material tank, thereby effectively removing residual pigment and clumps in the material tank. This helps to improve cleaning efficiency, avoid the impact of clumps of pigment on printing quality, and thus improve the overall quality of plastic film products.

[0019] By setting up turntable one and turntable two in conjunction with worm gear one, worm shaft one, and connecting shaft, the material trough can be flipped and can be stably maintained in the current flipped position. It will not rotate on its own due to the gravity of the material trough or other external forces, thus ensuring the stability of the material trough after flipping. This facilitates thorough cleaning of all corners inside the material trough, which helps to improve cleaning efficiency and avoids the impact of clumped pigment on printing quality.

[0020] By setting the worm gear 2 and worm 2 to cooperate with the connecting shaft, the material trough can be raised and lowered while the rotation position of the connecting shaft can be limited, thereby limiting the vertical position of the material trough and ensuring the stability of the material trough 3 when it is overturned.

[0021] By setting up a liftable and sliding pallet, staff can begin disassembling the printing rollers while cleaning the material tank, without having to wait for the material tank to be cleaned before handling the printing rollers. The two tasks can be carried out simultaneously, shortening the overall cleaning and maintenance time and improving maintenance efficiency. At the same time, the pallet allows the printing rollers to be disassembled without additional support tools, effectively simplifying the disassembly process. Attached Figure Description

[0040] like Figures 1 to 9As shown, this embodiment of the present invention provides a plastic film gluing and printing integrated machine, including a control cabinet 25 and a printing machine 26. The printing machine 26 is provided with a liftable material trough 3, and a printing roller 21 is rotatably mounted on the printing machine 26, located above the material trough 3. The control cabinet 25 is electrically connected to the printing machine 26. The printing machine 26 includes a base 1, with two supports 2 symmetrically fixed on the top of the base 1. The material trough 3 and the printing roller 21 are both located between the two supports 2. The base 1 and the supports 2 provide stable support for the operation of the printing machine 26. In use, the required pigment or glue is poured into the corresponding material trough 3. The operator manually adjusts the lifting height of the material trough 3 so that the printing roller 21 is partially immersed in the pigment or glue. The operator sets relevant parameters according to production requirements through the operation interface on the control cabinet 25 and starts the machine. The printing press 26 rotates the printing roller 21, conveying the plastic film to the area below the printing roller 21 via the conveyor roller on the printing press 26. The pigment or glue on the surface of the printing roller 21 is transferred to the plastic film, forming the desired printing pattern and completing the gluing operation. The control cabinet 25 controls the printing press 26 to perform the printing and gluing processes, which are disclosed as prior art and will not be elaborated here. The flipping component is used to flip the material tank 3. The flipping component is connected to the bracket 2 and the material tank 3 in the printing press 26, allowing the cleaning wastewater and residual pigment to flow out of the material tank 3 more smoothly. At the same time, it facilitates the thorough cleaning of all corners inside the material tank 3, thereby effectively removing residual pigment and clumps in the material tank 3, which helps to improve cleaning efficiency, avoid the impact of clumped pigment on printing quality, and thus help to improve the overall quality of the plastic film product.

[0041] As one implementation method in this embodiment, such as Figures 2 to 5As shown, the flipping assembly includes a turntable 6 and a turntable 7 that rotate inside two supports 2 respectively. A connecting block 4 is fixed to the side of each turntable 6 and turntable 7 that is close to each other. The material trough 3 is slidably connected to the connecting block 4. A worm gear 8 is fixed to the side of turntable 7 away from the connecting block 4. A worm 9 is rotatably mounted on one side of one support 2, meshing with the worm gear 8. A handwheel 10 is fixed to one end of the worm 9. A connecting shaft 5 is rotatably mounted between the two connecting blocks 4, with one end of the connecting shaft 5 passing through... Worm gear 8 is equipped with a limiting component for limiting the connecting shaft 5. When the material trough 3 needs to be flipped, the operator turns handwheel 10 to drive worm gear 9 to rotate around its own axis. Since worm gear 8 and worm gear 9 mesh with each other, the rotation of worm gear 9 will drive worm gear 8 to rotate. Worm gear 8 is fixed on the side of turntable 7 away from connecting block 4, so the rotation of worm gear 8 will drive turntable 7 to rotate around its axis. Turntable 6 and turntable 7 are respectively rotatably set inside the two supports 2, and the rotation... Connecting blocks 4 are fixed on the sides of disc 6 and turntable 7 that are close to each other. The material trough 3 is slidably connected to the connecting blocks 4. A connecting shaft 5 is rotatably provided between the two connecting blocks 4. Under the limiting action of the limiting component, the two connecting blocks 4 and the material trough 3 slidably set on them can rotate around the axis of turntable 7 as turntable 7 rotates, thereby realizing the flipping action of material trough 3. Since the worm gear transmission has self-locking property, when material trough 3 is flipped to the required position, worm gear 8 is self-locked by worm 9 and can be stably maintained in the current flipped position. It will not rotate on its own due to the gravity of material trough 3 or other external forces, thus ensuring the stability of material trough 3 after flipping. By flipping material trough 3 to a suitable angle, the cleaning wastewater and residual pigment can flow out of material trough 3 more smoothly. At the same time, it is convenient to thoroughly clean all corners inside material trough 3, thereby effectively removing residual pigment and clumps in material trough 3, which is conducive to improving cleaning efficiency, avoiding the impact of clump pigment on printing quality, and thus improving the overall quality of plastic film products.

[0042] In this embodiment, as Figures 2 to 7As shown, the limiting assembly includes a connecting plate 11 fixed to one side of the worm gear 8. A worm gear 13 rotates on one side of the connecting plate 11. One end of the connecting shaft 5 passes through the connecting plate 11 and is fixed to a worm gear 12. The worm gear 12 meshes with the worm gear 13. A handwheel 14 is fixed to one end of the worm gear 13. Two racks are symmetrically fixed at the bottom of the material trough 3. The racks slide within the connecting block 4. Gears are fixed at both ends of the connecting shaft 5. The racks at the bottom of the material trough 3 mesh with the gears at both ends of the connecting shaft 5. When the lifting height of the material trough 3 needs to be adjusted, the operator rotates the handwheel 14 to drive the worm gear 13 to rotate around its own axis. Since the worm gear 12 and the worm gear 13 mesh with each other, the rotation of the worm gear 13 will drive the worm gear 12 to rotate. The worm gear 12 is fixed to one end of the connecting shaft 5. The rotation of worm gear 12 will drive the connecting shaft 5 to rotate around its own axis, which in turn will drive the gears at both ends of the connecting shaft 5 to rotate synchronously. Since the rack at the bottom of the material trough 3 meshes with the gears at both ends of the connecting shaft 5 in pairs, according to the transmission principle of gear rack, the rotation of the gear will drive the rack to move in a straight line, thereby enabling the material trough 3 to rise and fall. As mentioned above, since the worm gear transmission has self-locking properties, the meshing between worm gear 12 and worm 13 can be used to realize the rising and falling of the material trough 3, and can also be used to limit the rotation position of the connecting shaft 5, thereby limiting the vertical position of the material trough 3. When the material trough 3 is flipped, worm gear 12, worm 13 and handwheel 14 can rotate synchronously with the rotation of worm gear 8, thereby ensuring the stability of the flipping of the material trough 3.

[0043] In this embodiment, as Figures 6 to 7 As shown, a liftable support plate 18 is slidably provided on one side of the connecting block 4. The lifting of the support plate 18 can be achieved by any existing method that enables the linear lifting of the support plate 18. One method is to drive it with a cylinder 17. Specifically, the cylinder 17 slides on one side of the connecting block 4, and the telescopic end of the cylinder 17 is fixed to the bottom of the support plate 18. A reinforcing block 20 is also fixed between the telescopic end of the cylinder 17 and the bottom of the support plate 18 to ensure the support stability of the support plate 18. The top of the support plate 18 is arc-shaped. When the material trough 3 is flipped, the top of the support plate 18 can rise to be in contact with the bottom surface of the printing roller 21. When washing the material tank 3, the corresponding printing roller 21 also needs to be disassembled for cleaning or replacement. The support plate 18 is used to support the printing roller 21 when replacing it. While cleaning the material tank 3, the staff can start disassembling the printing roller 21 without waiting for the material tank 3 to be cleaned before processing the printing roller 21. The two tasks can be carried out simultaneously, which shortens the overall cleaning and maintenance time and improves the maintenance efficiency. At the same time, when the material tank 3 is flipped, the support plate 18 can rise to support the printing roller 21. The printing roller 21 can be disassembled without additional support tools, which simplifies the disassembly process.

[0044] In this embodiment, as Figures 6 to 7As shown, a groove 16 is provided on one side of the connecting block 4, and the pallet 18 slides within the groove 16. The sliding of the pallet 18 can be any method in the prior art that can achieve linear sliding of the pallet 18, among which the method driven by the electric actuator 19 is one example. Specifically, the electric actuator 19 is fixed on the side of the connecting block 4 away from the material trough 3. A slider is slidably provided in the groove 16, and the top of the slider is fixed to the cylinder 17 mentioned above. The telescopic end of the electric actuator 19 passes through the groove 16 and is fixed to one side of the slider. A support block 15 is fixed at the bottom of the material trough 3. A groove is provided on one side of the support block 15. When the support block 15 and the side of the groove 16 that are close to each other are in contact, the groove 16 and the groove communicate with each other. Plate 18 can slide into the groove. When the material trough 3 needs to be cleaned, it needs to be lowered away from the printing roller 21 in the manner described above. One operator operates the material trough 3 to flip it for cleaning. After the material trough 3 is flipped, the support plate 18 is driven by the cylinder 17 to rise and support the printing roller 21. Another operator can disassemble the printing roller 21 at the same time. When the material trough 3 is lowered to the point where the support block 15 and the connecting block 4 are in contact, the slide 16 communicates with the groove. The support plate 18 can be pushed by the electric push rod 19 to drive the disassembled printing roller 21 to slide into the groove, thereby moving the printing roller 21 away from the printing machine 26. This effectively simplifies the disassembly process, improves the efficiency of cleaning and maintenance, and reduces the difficulty of operation.

[0045] In this embodiment, as Figures 8 to 9 As shown, both ends of the printing roller 21 are sequentially fitted with insert plates 22 and end plates 23. The insert plate 22 is located inside the end plate 23. A fixing shaft 24 is fixed between the insert plate 22 and the end plate 23. One end of the fixing shaft 24 is engaged with the bracket 2 via a bearing. The printing roller 21 has an abutment groove that abuts against the inner side of the insert plate 22. The abutment groove is used to limit the insertion of the insert plate 22, thereby helping to maintain the stability of the insertion of the insert plate 22. The distance from the outer side of the end plate 23 to the inner side of the bracket 2 is equal to the distance from the outer side of the insert plate 22 to the outer side of the printing roller 21. When it is necessary to disassemble the printing roller 21... First, the bearing at one end of the fixed shaft 24 is disconnected from the support frame 2. As mentioned above, under the support of the support plate 18, the fixed shafts 24 at both ends of the printing roller 21 are pulled to pull out the insert plate 22 and end plate 23 inside the printing roller 21. The distance from the outer side of the end plate 23 to the inner side of the support 2 is equal to the distance from the outer side of the insert plate 22 to the outer side of the printing roller 21. This ensures that when one side of the end plate 23 is in contact with the inner side of the support 2, the insert plate 22 just disengages from the printing roller 21, thus completing the quick disassembly of the printing roller 21 and improving the maintenance and replacement efficiency of the printing roller 21.

[0046] The working principle of the technical solution provided by this utility model is as follows:

[0047] In use, the required pigment or glue is poured into the corresponding material tank 3. The operator turns the handwheel 14 to drive the worm gear 13 to rotate. The rotation of the worm gear 13 will drive the worm wheel 12 to rotate. The worm wheel 12 is fixed to one end of the connecting shaft 5. The rotation of the worm wheel 12 will drive the connecting shaft 5 and the gears at both ends of the connecting shaft 5 to rotate synchronously. The rotation of the gears will drive the rack at the bottom of the material tank 3 to move in a straight line, thereby completing the lifting and lowering of the material tank 3, so that the printing roller 21 is partially immersed in the pigment or glue. The operator sets the relevant parameters according to the production requirements through the operation interface on the control cabinet 25, starts the printing machine 26 to make the printing roller 21 rotate, and transports the plastic film to the bottom of the printing roller 21 through the conveying roller on the printing machine 26. The pigment or glue on the surface of the printing roller 21 will be transferred to the plastic film to form the required printing pattern and complete the glue application operation.

[0048] When cleaning and maintenance are required, the operator first reverses the handwheel 14 to lower the material trough 3 until the support block 15 and the connecting block 4 are in contact, so that the material trough 3 is away from the printing roller 21. The operator then rotates the handwheel 10 to drive the worm gear 9 to rotate. The rotation of the worm gear 9 will drive the worm wheel 8 to rotate. The rotation of the worm wheel 8 will drive the turntable 7 to rotate. Under the meshing cooperation of the worm wheel 12 and the worm gear 13, the connecting shaft 5 is limited, so that the two connecting blocks 4 and the material trough 3 sliding on them rotate synchronously with the turntable 7, thereby realizing the flipping action of the material trough 3. Since the worm gear transmission has self-locking property, when the material trough 3 is flipped to the required position, the worm wheel 8 is controlled by the self-locking action of the worm gear 9 and can be stably maintained in the current flipped position. It will not rotate on its own due to the gravity of the material trough 3 or other external forces, thus ensuring the stability of the material trough 3 after flipping. After flipping, the material trough 3 is easy to clean thoroughly.

[0049] When cleaning the material tank 3, the corresponding printing roller 21 also needs to be disassembled for cleaning or replacement. One operator operates the material tank 3 to flip it over for cleaning. After the material tank 3 is flipped, the support plate 18 is driven by the cylinder 17 to rise and support the printing roller 21. Another operator can disassemble the printing roller 21 simultaneously. When disassembling the printing roller 21, first disconnect the bearing at one end of the fixed shaft 24 from the support frame 2. Under the support of the support plate 18, pull the fixed shafts 24 at both ends of the printing roller 21 respectively. Pull out the insert plate 22 and end plate 23 inside the printing roller 21. When one side of the end plate 23 is in contact with the inner side of the bracket 2, the insert plate 22 just disengages from the printing roller 21, completing the quick disassembly of the printing roller 21. When the material trough 3 descends to the point where the support block 15 is in contact with the connecting block 4, the slide 16 communicates with the groove. Under the pushing action of the electric push rod 19, the support plate 18 drives the disassembled printing roller 21 to slide into the groove, so that the printing roller 21 is away from the printing machine 26, which facilitates the subsequent cleaning and replacement of the printing roller 21.
