Description

Technical Field

[0001] The utility model relates to the technical field of protective film pressing, in particular to a pressing device for a protective film laminating machine. Background Art

[0002] A clamping device for a protective film laminating machine is divided into two forms: a pressure roller and a pressure plate. It is mainly used to apply a certain pressure to the protective film and the object to be laminated during the protective film laminating process, so that the protective film can be tightly and evenly laminated to the surface of the object to ensure the laminating quality. Its function is to ensure that there are no bubbles, wrinkles or gaps between the protective film and the object to be laminated when the protective film is laminated, thereby improving the appearance quality and performance stability of the product. Through appropriate pressure control and uniform compression distribution, high-quality protective film laminating effects can be achieved to meet the product protection and appearance requirements of different industries and application scenarios.

[0033] Refer to Figures 1 to 3, an embodiment provided by the present utility model: a pressing device for a protective film laminating machine, comprising a processing table 1 and two protective boxes 6. The processing table 1 is fixedly connected with support legs 2 by welding, and these support legs 2 provide support force for the whole device. The left end of the top side of the processing table 1 is carefully fixedly connected with two control consoles 3, and these two control consoles 3 facilitate the operator to perform precise control.

The driving ends of the cylinders 5 are fixedly connected with the protective boxes 6 by strong connecting pieces, and the protective boxes 6 have good protection performance and durability;

[0034] Bar-shaped openings 24 are carefully opened on the adjacent sides of the two protective boxes 6, and the bar-shaped openings 24 are convenient for restricting the sliding of subsequent components. The inner wall of the left end of one of the protective boxes 6 is closely fixedly connected with a driving component for driving the subsequent components to rotate. The driving component mainly includes a first motor 7, and the outside of the first motor 7 is fixedly connected to the inner wall of the left end of one of the protective boxes 6 by bolts, and the first motor 7 can provide stable and powerful power output. The driving end of the first motor 7 is precisely fixedly connected with a rotating shaft 8 by a coupling, and the rotating shaft 8 transmits the force of the rotating driving end of the first motor 7 to the subsequent components. The outside of the rotating shaft 8 is closely fixedly connected with a heating roller 9 by thermal sleeve fitting, and the heating roller 9 has good heat conduction performance and wear resistance, and can uniformly heat the protective film to improve the laminating effect;

[0035] In addition, driving wheels 10 are fixedly connected to both the front and rear ends of the driving component, and the driving wheels 10 have transmission performance. The front and rear ends of the rotating shaft 8 are respectively fixedly connected to the inside of the two driving wheels 10 by key connection to ensure the reliability of power transmission. A belt 11 is sleeved on the outside of the driving wheels 10, and the belt 11 has good elasticity and wear resistance, and can effectively transmit power to ensure the synchronous rotation of the two driving wheels 10 and the driven wheel 15. The inner wall of the right end of the protective box 6 is also fixedly connected with a fixed leg 12 by welding, and the fixed leg 12 has good stability and load-bearing capacity. The top end of the fixed leg 12 is rotatably connected with an I-shaped column 13 by a high-precision bearing, and the I-shaped column 13 can rotate flexibly at the top end of the fixed leg 12;

[0036] On the adjacent sides of the two I-shaped columns 13, connecting shafts 14 are fixedly connected by welding. The connecting shafts 14 are used to transmit the rotational force. The outside of the connecting shafts 14 is fixedly connected with driven wheels 15. The driven wheels 15 can work in coordination with the driving wheel 10 to achieve power transmission. The outside of the driven wheels 15 is sleeved inside the belt 11. Through the transmission of the belt 11, the driven wheels 15 can rotate synchronously with the rotation of the driving wheel 10. On the adjacent sides of the two driven wheels 15, connecting shafts 16 are also fixedly connected. The connecting shafts 16 have good precision and surface finish. The outside of the connecting shafts 16 is slidably connected with opening plates 17. The inside of the opening plates 17 is provided with sliding grooves matching the connecting shafts 16, so that the opening plates 17 can slide smoothly on the connecting shafts 16. On the adjacent sides of the two opening plates 17, a strip plate 18 is fixedly connected.

[0037] Refer to Figures 2 to 4 , on the bottom side of the strip plate 18, two reset components for resetting subsequent components are fixedly connected. The reset components specifically include fixed cylinders 19. The top sides of the two fixed cylinders 19 are firmly fixedly connected to the front and rear ends of the bottom side of the strip plate 18 by welding. The top side of the inner wall of the fixed cylinder 19 is tightly fixedly connected with a spring 20 by welding. The spring 20 has good elasticity and fatigue life. The bottom end of the spring 20 is fixedly connected with a round plate 21 by welding. The round plate 21 can slide smoothly on the inner wall of the fixed cylinder 19. The bottom side of the reset component is fixedly connected with a sliding column 22. The sliding column 22 and the round plate 21 are tightly connected by welding. The outside of the round plate 21 can slide on the inner wall of the fixed cylinder 19 without hindrance, ensuring the normal operation of the reset component. The bottom sides of the two sliding columns 22 are fixedly connected with a pressing plate 23 by welding. The surface of the pressing plate 23 is covered with a layer of soft rubber material, which can avoid damaging the protective film when pressing the protective film.

[0038] Refer to Figure 1 , Figure 5 and Figure 6 , on the right end of the bottom side of the processing table 1, a square frame 25 is fixedly connected by bolt fastening. The bottom side of the inner wall of the square frame 25 is fixedly connected with a power component for driving the subsequent components to rotate. The power component mainly includes a second motor 26. The bottom side of the second motor 26 is fixedly connected to the bottom side of the inner wall of the square frame 25 by fastening bolts. The second motor 26 can provide sufficient power to drive the subsequent components to work. The driving end of the second motor 26 is fixedly connected with a rotating shaft 27. The rotating shaft 27 has good strength and transmission performance. The top side of the power component is fixedly connected with a cross plate 28. The top side of the rotating shaft 27 is firmly fixedly connected to the bottom side of the cross plate 28 by key connection, ensuring the reliability of power transmission. The four sides of the cross plate 28 are all rotatably connected with rotating plates 29 through pin shafts;

[0039] The far ends of multiple rotating plates 29 are all rotatably connected to rotating columns 30 through bearings, and the rotating columns 30 can rotate flexibly under the drive of the rotating plates 29. A limiting disc 31 is fixedly connected to the bottom side of the rotating column 30. The diameter of the limiting disc 31 is larger than that of the rotating column 30, which can effectively limit the axial movement of the rotating column 30 and ensure its stability during operation. A limiting plate 32 is fixedly connected to the top side of the rotating column 30. The size of the limiting plate 32 is slightly larger than the cross-sectional size of the rotating column 30, which can prevent the connecting block 33 from disengaging from the rotating column 30 during the up and down movement. A connecting block 33 is fixedly connected to the top side of the limiting plate 32;

[0040] The outsides of multiple connecting blocks 33 can slide smoothly through chutes provided on the inner walls around the square frame 25. The top sides of the connecting blocks 33 are fixedly connected to clamping plates 34 by welding. The surfaces of the clamping plates 34 are polished and have good anti-slip performance, which can firmly clamp the object to be processed. The right end of the processing table 1 is slidably connected to a collecting plate 35 by means of the cooperation of a guide rail and a slider in a clever way. The bottom side of the collecting plate 35 is in close contact with the top side of the square frame 25, ensuring the stability of the collecting plate 35 during sliding. Vertical plates 36 are fixedly connected to the four circumferences of the top side of the collecting plate 35 by welding. The height of the vertical plates 36 is appropriate, which can effectively prevent the items placed on the collecting plate 35 from slipping.

[0041] Working principle: We place the protective film and the object to be bonded on the bottom side of the heating roller 9. Then, by driving two cylinders 5, we push the protective box 6 downward to slide, so that the heating roller 9 can be in contact with the protective film and the object to be bonded. Then, by driving the first driving motor 7, the rotating shaft 8 is driven to rotate, thus driving the driving wheel 10 to rotate. And through friction, the protective film and the object to be bonded can be transported to the right and pressed tightly. At the same time, the heating roller 9 heats the protective film and the object to be bonded to improve the pressing efficiency. Then, after being pressed tightly, the protective film and the object to be bonded are transported to the right under the pressing plate 23. At the same time, the heating roller 9 also drives two belts 11 to rotate, thus driving the fixed legs 12 to rotate, then driving the driven wheel 15 to rotate. Then, the driven wheel 15 drives the connecting shaft 16 to rotate. At this time, the connecting shaft 16 rotates around the driven wheel 15 as the center, thus pushing the opening plate 17 to slide up and down reciprocally. Then, the two opening plates 17 drive the strip plate 18 to slide. At this time, the strip plate 18 drives the two fixed cylinders 19 to slide up and down reciprocally. Then, the fixed cylinders 19 drive the pressing plate 23 to press against the protective film and the object to be bonded. At this time, it will press against the pressing plate 23 and provide a reverse force, and then push the two sliding columns 22 to slide, thus pushing the circular plate 21 to slide and compress the spring 20, so that the spring 20 can store elastic potential energy, making the pressing plate 23 closely fit the protective film and the object to be bonded, enabling it to adapt to protective films and objects to be bonded with different thicknesses. At the same time, by using the reciprocating pushing of the pressing plate 23 on the protective film and the object to be bonded, the bent protective film and the object to be bonded can become flat, without manual flattening, thus improving the working efficiency.

[0042] Then, the pressed and flattened protective film and the object to be bonded will fall onto the top of the collection plate 35. As the protective film and the object to be bonded accumulate, when taking them, by driving the second driving motor 26, the rotating shaft 27 is driven to rotate, thus driving the cross plate 28 to rotate. As the cross plate 28 rotates, it drives multiple rotating plates 29 to slide and rotate towards the adjacent side, thus pulling the rotating column 30 to slide. By driving the limiting plate 32 to slide through the rotating column 30, the connecting block 33 is driven to slide, and then the clamping plate 34 is driven to slide. As the multiple clamping plates 34 slide towards the adjacent side, the multilayered and staggered protective film and the object to be bonded are sorted out. At this time, when holding the pull ring at the top of the vertical plate 36 and pulling up the vertical plate 36, the collection plate 35 and the protective film and the object to be bonded above are taken away, thus eliminating the need to manually sort out the uneven protective film and the object to be bonded, and then reducing human resources.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
