Description

Technical Field

[0001] The utility model relates to the technical field of decorative plate processing, in particular to a protective plate laminating mechanism. Background Art

[0002] A protective plate is a plate that covers the surface of a decorative plate. Its main function is to protect the decorative plate from scratches, wear, pollution and other damages during daily use. When the protective plate is processed, a layer of film needs to be coated on its surface. This film can provide additional protection and enhance the original performance of the protective plate.

[0003] The current coating principle for protective plates is to unwind the film through an unwinding mechanism, press the film onto the protective plate through a roller mechanism, and finally cut the film to complete the coating operation. For example, a thermal insulation board laminating machine is disclosed in Chinese patent announcement number "CN108891014A".

[0004] In the existing coating machine structure, due to the different thicknesses of the plates, in order to adapt to plates of different thicknesses, two control components such as cylinders, electric push rods or screws are usually used at both ends of the pressure roller to adjust the horizontal height. However, since the control components on both sides are independently controlled, errors in the height of the two ends are likely to occur during the actual adjustment process, causing the pressure roller to be non-level with the plate surface, thereby affecting the lamination effect. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art that the control members on both sides are independently controlled, which easily leads to errors in the height of both ends during the actual adjustment process, and thus a protective plate laminating mechanism is proposed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A protective plate laminating mechanism is designed, comprising a machine platform and a conveying mechanism installed on the machine platform, and a film placing mechanism, a cutting mechanism and a pressing mechanism are also installed above the machine platform;

[0008] The pressing mechanism includes at least two connecting seats mounted on the machine platform, a guide rod is movably inserted into the inner side of the connecting seat, the bottom of the guide rod is connected to a pressure roller seat through an elastic structure, and a pressure roller is rotatably connected between the two pressure roller seats;

[0009] A synchronization component for maintaining the synchronous movement of the two guide rods is also provided at the bottom of the machine.

[0010] Furthermore, the elastic structure includes a connecting plate fixedly installed at the bottom of the guide rod, and a spring and an adjusting member are threadedly connected to the outside of the guide rod, and the two ends of the spring are respectively in contact between the adjusting member and the connecting seat.

[0011] Furthermore, a guide groove is provided on the outer side of the connecting seat, and a guide bolt is threadedly connected to the outer side of the guide rod, and at least a portion of the guide bolt slides in the guide groove.

[0012] Furthermore, a plug rod is fixedly installed on the top of the pressure roller seat, and the plug rod passes through and is plugged into the connecting plate. A positioning glass bead is embedded on the outer side of the plug rod to stop above the connecting plate.

[0013] Furthermore, the synchronization assembly includes a bearing seat fixed on the machine platform, a shaft is rotatably connected in the bearing seat, and gears are fixedly installed at both ends of the shaft;

[0014] A notch is also provided on the outer side of the connecting seat, and the gear is placed in the notch.

[0015] Furthermore, a plane is provided on the outer side of the guide rod along the axial direction, a plurality of latching teeth are provided on the plane, and the gear is engaged with the plurality of latching teeth.

[0016] The utility model proposes a protective plate laminating mechanism, which has the following beneficial effects: the utility model adopts an elastic structure to realize floating support for the pressure roller, and when protective plates of different thicknesses pass by, the elastic structure is deformed, so that the plates of different thicknesses can be pressed. Compared with the current adjustment method, there is no need to introduce an external control source, thereby reducing the manufacturing cost. Secondly, the utility model adopts the design of a synchronous component to ensure that the guide rods on both sides are in a synchronous movement state, thereby ensuring that the two ends of the pressure roller are always in horizontal contact with the upper end of the protective plate, and also avoiding the problem of errors in the adjustment height of the two sides resulting in different pressing forces at the two ends when the two traditional control parts move independently.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figures 1-4 This is an embodiment of the present invention, which discloses a protective plate laminating mechanism. Specifically, the laminating mechanism includes a machine 1 and a conveying mechanism 2 installed on the machine 1. A film placing mechanism 3, a cutting mechanism 4, and a pressing mechanism 5 are also installed above the machine 1. The conveying mechanism 2, the film placing mechanism 3, and the cutting mechanism 4 described in this embodiment have been disclosed in the prior art and will not be described in detail here.

[0024] The pressing mechanism 5 includes at least two connecting seats 51 mounted on the machine platform 1. A guide rod 52 is movably inserted into the inner side of the connecting seat 51. The upper end of the guide rod 52 passes through the machine platform 1. The bottom of the guide rod 52 is connected to a pressure roller seat 54 via an elastic structure 53. A pressure roller 55 is rotatably connected between the two pressure roller seats 54.

[0025] A synchronization component 6 for maintaining the synchronous movement of the two guide rods 52 is also provided at the bottom of the machine platform 1 .

[0026] In some embodiments, the elastic structure 53 in the present invention includes a connecting plate 531 fixedly installed at the bottom of the guide rod 52, and a spring 532 and an adjusting member 533 are threadedly connected on the outside of the guide rod 52. The two ends of the spring 532 respectively contact between the adjusting member 533 and the connecting seat 51.

[0027] Specifically, the adjusting member 533 described in this embodiment is configured as a nut, which is threadedly connected to the guide rod 52. By adjusting the position of the nut, the spring 532 can be squeezed. Those skilled in the art know that when the effective length of the spring 532 is compressed, the reverse thrust increases. In this way, the downward pressure of the pressure roller 55 can be adjusted by adjusting the position of the nut to meet the pressing force requirements of protective plates of different thicknesses when coated within a certain range.

[0028] In addition, in the embodiment of the present utility model, a guide groove 511 is provided on the outer side of the connecting seat 51, and a guide bolt 521 is threadedly connected to the outer side of the guide rod 52, and at least a portion of the guide bolt 521 slides in the guide groove 511, that is, in this embodiment, the sliding manner of the guide bolt 521 and the guide groove 511 is used to guide the sliding of the guide rod 52. Of course, when the guide bolt 521 is removed, the entire guide rod 52 can also be taken out from the inner side of the connecting seat 51. Furthermore, the guide groove 511 described in this embodiment is set as a straight groove.

[0029] On the basis of the above embodiment, in this embodiment, a plug rod 541 is fixedly installed on the top of the pressure roller seat 54, and the plug rod 541 passes through and is plugged into the connecting plate 531. A positioning glass bead 542 is embedded on the outer side of the plug rod 541 to stop above the connecting plate 531. By adopting the design mode of the positioning glass bead 542, the pressure roller seat 54 can be easily disassembled to improve the convenience of replacing and repairing the pressure roller 55. During disassembly, the telescopic end of the positioning glass bead 542 is pressed to retract it. At this time, the entire pressure roller seat 54 can be pulled downward to separate the pressure roller seat 54 from the connecting plate 531.

[0030] In some embodiments, the synchronization assembly 6 of the present invention includes a bearing seat 61 fixed on the machine table 1, a shaft 62 is rotatably connected to the bearing seat 61, and gears 63 are fixedly installed at both ends of the shaft 62;

[0031] A notch is further formed on the outer side of the connecting seat 51 , and the gear 63 is placed in the notch.

[0032] On the basis of the above embodiment, in this embodiment, a plane is provided on the outer side of the guide rod 52 along the axial direction, and a plurality of latching teeth 64 are provided on the plane. The gear 63 is engaged with the plurality of latching teeth 64 .

[0033] That is, in this embodiment, by adopting the method of coaxially fixing two gears 63, when the film is pressed, when protective plates of different thicknesses pass under the pressing roller 55, the pressing roller 55 will float upward or downward, and the guide rods 52 on both sides will move at this time. Since the two gears 63 are respectively engaged with the latch teeth 64 on the sides of the two guide rods 52, the guide rods 52 on both sides can be ensured to move synchronously under the drive of coaxial rotation, so that the pressing adaptation of protective plates of different thicknesses can be achieved, while ensuring the pressing of the film, the adjustment workload is effectively reduced.

[0034] In conclusion, the elastic structure 53 is arranged to achieve floating support of the compression roller 55, when the protective plate with different thickness passes, the elastic structure 53 is deformed, so that the plate material with different thickness can be compressed, compared with the current adjustment mode, an external control source is not needed, so that the manufacturing cost is reduced, and secondly, the synchronous assembly 6 is adopted in the utility model, so that the guide rods 52 on the two sides are in the synchronous movement state, so that the two ends of the compression roller 55 are always in contact with the upper end of the protective plate, and the problem that the compression force of the two ends is different due to the error of the adjustment height of the two sides when the two control members independently move and adjust is avoided.

[0035] The above is only the preferred specific implementation mode of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the technical field according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model makes equivalent replacement or change, should be covered in the protection scope of the utility model.
