Description

Technical Field

[0001] This invention relates to the field of coating machine technology, specifically a coating machine for antistatic pre-coating film processing. Background Technology

[0002] Pre-coated film process greatly simplifies the coating process because the coating equipment does not require an adhesive heating and drying system. It is also very convenient to operate, can be started up as needed, and has great production flexibility. At the same time, it has no solvent odor and no environmental pollution. More importantly, it can completely avoid defects such as bubbles and delamination. Its finished products have extremely high transparency and have broad application prospects and promotion value.

[0003] Current laminating machines, in the process of attaching antistatic pre-coated film to cardboard, use a feeding mechanism to move the cardboard toward the pre-coated film, allowing the pre-coated film to adhere to the cardboard and thus perform the laminating operation. However, in the existing laminating machines, the cardboard cannot automatically enter the laminating area one by one during the feeding operation, resulting in a low degree of automation and orderliness in the laminating process. Consequently, the laminating efficiency of the pre-coated film cannot meet actual production needs. Therefore, this paper proposes a laminating machine for processing antistatic pre-coated film to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a laminating machine for antistatic pre-coating film processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A laminating machine for processing antistatic pre-coated film includes a support platform with a frame fixed on it. A conveyor roller is rotatably mounted on the frame, and a conveyor belt is driven to the conveyor roller. A film winding roller and a heating roller are rotatably mounted on the support platform, conveying a pre-coated film above the conveyor belt. A motor is fixed on the support platform, and a stepping conveyor assembly is driven to the motor to drive the conveyor roller to rotate in a stepwise manner. A reciprocating lifting assembly is also driven to the motor, and a top frame is fixed on the reciprocating lifting assembly. A film cutting blade vertically corresponding to the pre-coated film is fixed at the bottom of the top frame. A U-shaped tray is fixed on the support platform, and several pieces of cardboard are stacked inside the U-shaped tray. Baffles I are fixed on both sides of the U-shaped tray. The system includes a baffle II, a cylinder fixed on the support platform, a sliding frame horizontally slidably mounted on the support platform at the free end of the cylinder, a push plate horizontally opposite to the highest cardboard piece fixed on the sliding frame, a V-shaped frame fixed on the U-shaped support plate, and pressure rollers I and II for pressing the cardboard mounted on the V-shaped frame. An upper plate for vertically pushing the cardboard is vertically mounted inside the U-shaped support plate, a spring ring fixed at the bottom of the upper plate, and a lifting sleeve vertically sliding through the U-shaped support plate fixed at the bottom of the spring ring. A threaded column is threaded into the lifting sleeve. A snap-fit ​​slider slidably embedded in the side wall of the lifting sleeve is fixed on the support platform. A transmission assembly is mounted on the sliding frame, and the transmission assembly drives the threaded column to rotate in a stepwise manner.

[0007] As an improvement of the present invention: the stepping conveyor assembly includes an incomplete gear fixed coaxially with the output shaft of the motor, a gear I that intermittently meshes with the incomplete gear is fixed coaxially on the conveying roller, and a gear II that meshes with gear I is fixed coaxially on the film winding roller.

[0008] As an improvement of the present invention: the reciprocating lifting assembly includes a turntable fixed coaxially with the output shaft of the motor, a guide frame fixed on the frame, a lifting frame fixed to the top frame vertically slidably mounted on the guide frame, a transmission plate hinged on the lifting frame, and the lower end of the transmission plate eccentrically hinged to the turntable.

[0009] As an improvement of the present invention: the transmission assembly includes a transmission gear fixedly sleeved on the lower end of the threaded column, a vertically arranged guide column fixed on the sliding frame, a transmission sleeve block vertically slidably mounted on the guide column, and a rack intermittently meshing with the transmission gear fixed on the transmission sleeve block.

[0010] As an improvement of the present invention: wedge block I and wedge block II are fixed at the bottom of the support platform and are arranged opposite to the transmission sleeve block. An insert plate is slidably installed on the transmission sleeve block. A push spring is fixed between the insert plate and the transmission sleeve block. Two vertically distributed triangular grooves are opened on the guide column. A triangular block that is adapted to be inserted into the triangular groove is fixed on the insert plate.

[0011] As an improvement of the present invention: a guide plate is fixed on the baffle I, the top of the guide plate is at the same horizontal height as the top of the baffle I, the lower end of the guide plate abuts against the conveyor belt, two side limiting plates are symmetrically fixed inside the frame, a support plate is fixed on the frame, and the conveyor belt is located between the limiting plate and the support plate.

[0012] As an improvement of the present invention: a rotating plate is rotatably mounted on one end of the V-shaped frame, and pressure roller I and pressure roller II are respectively rotatably mounted on both ends of the rotating plate. A locking post is rotatably mounted on pressure roller II, and a locking assembly for positioning the locking post is mounted on the V-shaped frame.

[0013] As an improvement of the present invention: the snap-fit ​​assembly includes a U-shaped limiting block fixed to the other end of the V-shaped frame, a pair of trapezoidal snap-fit ​​blocks are slidably mounted on the U-shaped limiting block, an extension plate is fixed on the trapezoidal snap-fit ​​blocks, and a connecting spring is fixed between the extension plate and the U-shaped limiting block.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This invention uses a cylinder to drive a sliding frame to reciprocate, allowing a pusher plate mounted on the sliding frame to push the stacked cardboard inside the U-shaped tray. The upper plate moves upward step by step during the sliding of the pusher plate, ensuring that the stacked cardboard can move vertically to replenish the material. This achieves horizontal alignment between the next cardboard and the pusher plate, effectively ensuring automatic, orderly, and stable feeding of the laminating operation and greatly improving the laminating effect of the cardboard.

[0016] In this invention, an incomplete gear can drive gear I to rotate in a stepwise manner during rotation, while gear I can drive gear II to rotate in the opposite direction. This allows the pre-coated film and the conveyor belt to move synchronously in a stepwise manner for lamination, ensuring that the pre-coated film and the cardboard conveyed on the conveyor belt correspond in an orderly and segmented manner. The film cutting blade, under the transmission action of the vertical lifting component, works in an orderly manner with the conveying action of the cardboard, ensuring automatic cutting of the cardboard and significantly improving the lamination efficiency of the cardboard.

Detailed Implementation

[0030] The technical solution of the present invention will be further described in detail below with reference to specific embodiments:

[0031] Example 1

[0032] Please see Figure 1-12A laminating machine for antistatic pre-coated film processing includes a support platform 1, a frame 5 fixed on the support platform 1, a conveyor roller 50 rotatably mounted on the frame 5, a conveyor belt 23 drivenly connected to the conveyor roller 50, a film winding roller 2 and a heating roller 4 rotatably mounted on the support platform 1, the heating roller 4 and the film winding roller 2 conveying a pre-coated film 3 located above the conveyor belt 23, a motor 6 fixed on the support platform 1, a stepping conveyor assembly driven by the motor 6 to drive the conveyor roller 50 to rotate in steps, a reciprocating lifting assembly driven by the motor 6, a top frame 12 fixed on the reciprocating lifting assembly, a film cutting blade 22 vertically corresponding to the pre-coated film 3 fixed at the bottom of the top frame 12, a U-shaped tray 16 fixed on the support platform 1, several cardboard pieces 17 stacked inside the U-shaped tray 16, and baffles I 38 and II 39 fixed on both sides of the U-shaped tray 16 respectively. A cylinder 32 is fixed on the support platform 1. A sliding frame 19 is fixed to the free end of the cylinder 32 and is horizontally slidably mounted on the support platform 1. A push plate 20 is fixed on the sliding frame 19 and is horizontally opposite to the highest cardboard 17. A V-shaped frame 15 is fixed on the U-shaped support plate 16. A pressure roller I13 and a pressure roller II14 for pressing the cardboard 17 are installed on the V-shaped frame 15. An upper top plate 51 for vertically pushing the cardboard 17 is vertically slidably mounted inside the U-shaped support plate 16. A spring ring 40 is fixed to the bottom of the upper top plate 51. A lifting sleeve 25 that slides vertically through the U-shaped support plate 16 is fixed to the bottom of the spring ring 40. A threaded column 27 is threadedly connected inside the lifting sleeve 25. A snap-fit ​​slider 24 that is slidably embedded in the side wall of the lifting sleeve 25 is fixed on the support platform 1. A transmission assembly is installed on the sliding frame 19. The transmission assembly is used to drive the threaded column 27 to rotate in a stepping manner.

[0033] This device uses a U-shaped tray 16 to store cardboard 17. Multiple cardboard 17s are stacked in the U-shaped tray 16. The pusher plate 20 pushes the cardboard 17s onto the conveyor belt 23. The rotating film roller 2 winds the pre-coated film 3 to convey and coat the cardboard 17. The heating roller 4 squeezes, guides, and heats the conveyed pre-coated film 3. The cutting blade 22 moves down to cut the pre-coated film 3 on the cardboard 17, completing the coating operation of the cardboard 17.

[0034] The stepping conveyor assembly of this device includes an incomplete gear 8 coaxially fixed to the output shaft of the motor 6, a gear I9 intermittently meshing with the incomplete gear 8 coaxially fixed to the conveyor roller 50, and a gear II10 meshing with the gear I9 coaxially fixed to the film roll 2. The reciprocating lifting assembly includes a turntable 7 coaxially fixed to the output shaft of the motor 6, a guide frame 49 fixed to the frame 5, a lifting frame 11 fixed to the top frame 12 vertically slidably mounted on the guide frame 49, a transmission plate 48 hinged to the lifting frame 11, and the lower end of the transmission plate 48 eccentrically hinged to the turntable 7.

[0035] With the above configuration, motor 6 can drive incomplete gear 8 to rotate. Incomplete gear 8 intermittently meshes with gear I9. Gear I9 can drive conveyor roller 50, which is fixed coaxially with it, to rotate. Conveyor roller 50 drives conveyor belt 23 to convey, so that conveyor belt 23 drives cardboard 17 to move stepwise to below film cutting blade 22. Meanwhile, gear I9 drives gear II10, which meshes with it, to rotate. Gear II10 drives film winding roller 2 to rotate to achieve stepwise winding of pre-coated film 3. The movement directions of pre-coated film 3 and cardboard 17 are kept synchronized.

[0036] Meanwhile, as turntable 7 rotates, it pulls lifting frame 11 vertically back and forth via transmission plate 48. When incomplete gear 8 is not engaged with gear 19 during rotation, pre-coated film 3 and cardboard 17 remain stationary. Turntable 7 drives lifting frame 11 and top frame 12 vertically downward via transmission plate 48, enabling film cutting blade 22 to cut the pre-coated film 3 on cardboard 17, completing the lamination operation on cardboard 17. The above operation realizes step-by-step conveying of cardboard 17 and automatic film cutting, significantly improving the lamination efficiency of cardboard 17.

[0037] The transmission components of this device include a transmission gear 26 fixedly sleeved on the lower end of the threaded column 27, a vertically arranged guide column 33 fixed on the sliding frame 19, a transmission sleeve block 30 vertically slidably mounted on the guide column 33, and a rack 31 fixed on the transmission sleeve block 30 that intermittently meshes with the transmission gear 26. Wedge blocks I28 and II29, opposite to the transmission sleeve block 30, are fixed at the bottom of the support platform 1. An insert plate 34 is slidably mounted on the transmission sleeve block 30, and a push spring 37 is fixed between the insert plate 34 and the transmission sleeve block 30. Two vertically distributed triangular grooves 35 are formed on the guide column 33, and a triangular block 36 that is fitted into the triangular grooves 35 is fixed on the insert plate 34.

[0038] With the above structural configuration, the cylinder 32 drives the sliding frame 19 to reciprocate, causing the pusher plate 20 to move towards the cardboard 17. The uppermost cardboard 17 inside the U-shaped tray 16 is pushed by the pusher plate 20 onto the conveyor belt 23 for lamination. The remaining cardboard 17 is blocked by the baffle 138 and will not be carried onto the conveyor belt 23 by the uppermost cardboard 17, thus achieving the effect of feeding cardboard 17 individually.

[0039] During the above process, due to the reciprocating motion of the sliding frame 19, the transmission sleeve 30 can reciprocate linearly. When the transmission sleeve 30 slides against the wedge block I28, the transmission sleeve 30 moves downward, so that the triangular block 36 and the lower triangular groove 35 on the guide post 33 are engaged and matched. The rack 31 and the transmission gear 26 are at the same horizontal height. Then the sliding frame 19 moves in the opposite direction, and the transmission sleeve 30 drives the rack 31 to move and then engages with the transmission gear 26. The transmission gear 26 drives the threaded post 27 to rotate. The threaded post 27 drives the lifting sleeve 25 to move vertically upward under the guidance of the locking slider 24. At this time, the lifting sleeve 25 is pushed upward by the spring ring 40. The plate 51 moves upward to vertically push the stacked cardboard 17, making the cardboard 17 fit tightly together. At the same time, it ensures that the next cardboard 17 is horizontally aligned with the push plate 20. When the transmission sleeve 30 abuts against the wedge block II 29, the triangular block 36 is inserted into the upper triangular groove 35 on the guide post 33, and the transmission sleeve 30 is reset, that is, the height of the rack 31 is higher than the transmission gear 26. This process is repeated, so that the sliding frame 19 slides back and forth once, the cardboard 17 is fed vertically upward once, and the top cardboard 17 is pushed and fed once, realizing the automatic feeding effect of the cardboard 17. The efficiency and orderliness of the cardboard 17 lamination operation are significantly improved.

[0040] Example 2

[0041] Please see Figure 1-12 Based on Embodiment 1, in addition, a guide plate 18 is fixed on the baffle I38 of this device. The top of the guide plate 18 is at the same horizontal height as the top of the baffle I38. The lower end of the guide plate 18 abuts against the conveyor belt 23. Two side limiting plates 47 are symmetrically fixed inside the frame 5. A support plate 46 is fixed on the frame 5. The conveyor belt 23 is located between the limiting plate 47 and the support plate 46.

[0042] Based on the above configuration, the cardboard 17 pushed by the pusher plate 20 from the U-shaped pallet 16 slides along the guide ramp 18 toward the conveyor belt 23. The guide ramp 18 guides the cardboard 17 during the feeding process, while the side limiting plate 47 and the support plate 46 vertically limit the sliding conveyor belt 23, ensuring that the conveyor belt 23 smoothly and linearly conveys the cardboard 17, effectively improving the lamination effect.

[0043] In addition, a rotating plate 21 is rotatably mounted on one end of the V-shaped frame 15, and pressure rollers I13 and II14 are rotatably mounted on both ends of the rotating plate 21, respectively. A locking post 41 is rotatably mounted on the pressure roller II14, and a locking assembly for positioning the locking post 41 is mounted on the V-shaped frame 15.

[0044] Specifically, the snap-fit ​​assembly includes a U-shaped limiting block 45 fixed to the other end of the V-shaped frame 15, a pair of trapezoidal snap-fit ​​blocks 42 slidably mounted on the U-shaped limiting block 45, an extension plate 43 fixed on the trapezoidal snap-fit ​​blocks 42, and a connecting spring 44 fixed between the extension plate 43 and the U-shaped limiting block 45.

[0045] The pressure rollers I13 and II14 limit the top of the cardboard 17 inside the U-shaped tray 16. The combined limiting function of pressure rollers I13, II14 and the top plate 51 ensures that the cardboard 17 can fit tightly together, and that the pusher plate 20 can push one cardboard 17 for sliding feeding by moving back and forth once.

[0046] The rotating plate 21 can drive the pressure roller II14 to rotate clockwise, causing the locking post 41 to push against the trapezoidal locking block 42, so that the two trapezoidal locking blocks 42 move away from each other. Finally, the locking post 41 moves between the trapezoidal locking block 42 and the U-shaped limiting block 45. The two trapezoidal locking blocks 42 abut under the elastic action of the connecting spring 44, thereby limiting the position of the locking post 41 and ensuring that the pressure roller II14 and pressure roller I13 abut against the cardboard 17, thus effectively limiting the cardboard 17. The rotating plate 21 can be rotated and adjusted, which facilitates the stacking of cardboard 17 into the U-shaped tray 16.

[0047] In summary, the present invention uses a cylinder 32 to drive the sliding frame 19 to reciprocate, so that the push plate 20 installed on the sliding frame 19 can push the cardboard 17 stacked inside the U-shaped tray 16. The upper plate 51 can move upward step by step during the sliding of the push plate 20, ensuring that the stacked cardboard 17 can move vertically to replenish it, so that the next cardboard 17 is horizontally aligned with the push plate 20. This effectively ensures the automatic, orderly and stable feeding operation of the laminating operation, and greatly improves the laminating effect of the cardboard 17. In this invention, the incomplete gear 8 can drive gear I9 to rotate in a stepwise manner during rotation, and gear I9 can drive gear II10 to rotate in the opposite direction, so that the pre-coated film 3 and the conveyor belt 23 move synchronously in a stepwise manner to perform film coating. This ensures that the cardboard 17 conveyed one by one on the pre-coated film 3 and the conveyor belt 23 are orderly and segment by segment. The film cutting blade 22 is driven by the vertical lifting component and works in an orderly manner with the conveying action of the cardboard 17, which ensures the automatic cutting of the cardboard 17 and significantly improves the film coating efficiency of the cardboard 17.
