Description

Technical Field

[0001] This utility model relates to the field of film coating machine technology, and in particular to a correction device for a film feeding mechanism. Background Technology

[0002] A laminating machine is a machine that applies a thin film, such as polyester film, to metal sheets (plates). It is used to apply polymer films, such as polyester film, to thin sheets of color-coated steel, galvanized steel, aluminum, or stainless steel. It is primarily used in the pre-processing lamination stage of metal processing. When laminating sheets, the film must be aligned with the sheet, meaning the two ends of the film's width direction must be aligned with the two ends of the sheet's width direction to ensure accurate lamination.

[0003] In existing methods for laminating metal sheets, deviations can occur when changing to different rolls of plastic film, leading to misalignment of the film and poor lamination results. This reduces work efficiency. Furthermore, when lamination stops, the winding drum can rotate excessively due to inertia, causing too much film to be released from the drum and resulting in insufficient tension. Consequently, the film cannot be evenly applied to the metal sheet during the next lamination. Therefore, there is an urgent need for a correction device for the film feeding mechanism.

Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0033] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0034] The following description, in conjunction with the accompanying drawings, details a correction device for a film-laying mechanism provided in this application, through specific embodiments and application scenarios.

[0035] Example 1:

[0036] like Figures 1 to 5As shown in the figure, this application embodiment provides a correction device for a film feeding mechanism, including a base plate 1, a mounting frame 2, a winding drum 3, and a drive motor 4; a slide rail 11 is fixedly installed on the base plate 1, and a slider 21 is provided at the bottom end of the mounting frame 2. The slider 21 is slidably installed on the slide rail 11. A pushing structure 5 is provided on the base plate 1, and the pushing structure 5 can push the mounting frame 2 to slide along the slide rail 11, so that the center line of the material installed on the winding drum 3 is aligned with the center line of the base plate 1.

[0037] Furthermore, the pushing structure 5 includes a fixing block 51 and a connecting block 53. The fixing block 51 is fixedly installed on the base plate 1, and a sliding groove 52 is provided on the fixing block 51. One end of the connecting block 53 is slidably installed in the sliding groove 52, and the other end is fixedly connected to the mounting bracket 2. A pushing motor 54 is fixedly installed on the fixing block 51. The output shaft of the pushing motor 54 extends into the sliding groove 52 and is fixedly connected to a gear 55. A toothed groove 56 is provided on the connecting block 53, and the gear 55 meshes with the toothed groove 56.

[0038] Furthermore, the fixing block 51 is provided with a limiting groove 57 that communicates with the sliding groove 52, and a limiting block 58 is fixedly installed on the connecting block 53, and the limiting block 58 is slidably installed in the limiting groove 57.

[0039] In this embodiment of the application, due to the above-described structure, the winding drum 3 is rotatably mounted on the mounting frame 2, and the drive motor 4 is fixedly mounted on the mounting frame 2. The output shaft of the drive motor 4 is fixedly connected to the winding drum 3. After changing the material, the center line of the material on the winding drum 3 is detected by an external optical sensor to see if the center line of the bottom plate 1 is aligned. If they are not aligned, the motor 54 is started, which drives the gear 55 to rotate. Since the gear 55 is meshed with the tooth groove 56, the rotation of the gear 55 will drive the connecting block 53 to slide in the sliding groove 52. The sliding of the connecting block 53 will drive the mounting frame 2 to slide along the slide rail 11, thereby making the center line of the material on the winding drum 3 aligned with the center line of the bottom plate 1, ensuring that the material is conveyed along the center line of the production line during the film feeding process, thereby ensuring its film coating effect.

[0040] The limit block 58 will slide together with the connecting block 53. When the limit block 58 slides to the emergency stop button 59 at both ends, the push motor 54 will stop, which can prevent the push mechanism 5 from being over-adjusted and causing the slider 21 to slide out of the slide rail 11.

[0041] Example 2:

[0042] like Figure 2 , Figure 6 , Figure 7 and Figure 8As shown, in this embodiment, in addition to the structural features of the aforementioned embodiment, a connecting frame 6 is fixedly installed on the base plate 1, and a movable roller 7 and a fixed roller 8 are movably installed on the connecting frame 6. The movable roller 7 and the fixed roller 8 are vertically offset. The distance between the movable roller 7 and the fixed roller 8 can be adjusted by adjusting the structure 9 so that the material wound on the movable roller 7 and the fixed roller 8 is always in a taut state.

[0043] Furthermore, the connecting frame 6 is provided with a pair of adjustment grooves 61, each of which is slidably mounted with an adjustment block 62, and each of which is provided with a sliding groove 64. The two ends of the movable roller 7 are respectively slidably mounted in the pair of sliding grooves 64, and the fixed roller 8 is rotatably mounted on the connecting frame 6. A feedback device 65 is provided in the sliding groove 64, which is used to provide feedback that the material is always in a taut state.

[0044] Furthermore, the feedback device 65 includes a first spring 651 and a feedback button 652. One end of the first spring 651 is fixedly connected to the end of the movable roller 7 facing the fixed roller 8, and the other end is fixedly connected to the slide groove 64. The slide groove 64 is provided with the feedback button 652 at the end of the first spring 651 that is fixedly connected to it.

[0045] Furthermore, the adjustment structure 9 includes a rotating block 91, and the connecting frame 6 is provided with a movable cavity 93 communicating with the adjustment groove 61. The rotating block 91 is rotatably installed in the movable cavity 93. A plurality of inclined blocks 94 are evenly distributed circumferentially at one end of the rotating block 91 facing the adjustment block 62. A plurality of corresponding inclined grooves 63 are provided at one end of the adjustment block 62 facing the rotating block 91. The inclined grooves 63 are pushed to abut against the inclined blocks 94 by the pressing member 95. The rotating block 91 can rotate around its axis by the driving device 92, thereby pushing the adjustment block 62 to slide.

[0046] Furthermore, the drive device 92 includes an adjusting motor 921, a first adjusting gear 922, and a second adjusting gear 923. The adjusting motor 921 is fixedly mounted on the connecting frame 6. The output shaft of the adjusting motor 921 extends into the movable cavity 93 and is fixedly mounted with the first adjusting gear 922. The second adjusting gear 923 is fixedly mounted on the end of the rotating block 91 facing away from the adjusting block 62. The first adjusting gear 922 and the second adjusting gear 923 are meshed together.

[0047] Furthermore, the pressing member 95 includes a connecting column 951 and a pressing plate 952. The connecting frame 6 is provided with a pressing groove 953 that communicates with the adjusting groove 61. One end of the connecting column 951 is slidably installed in the pressing groove 953, and the other end is fixedly connected to the pressing plate 952. The pressing plate 952 pushes the adjusting block 62 so that the plurality of inclined grooves 63 on it abut against the plurality of inclined blocks 94 respectively. A second spring 954 is sleeved on the connecting column 951. One end of the second spring 954 is fixedly connected to the pressing plate 952, and the other end is fixedly connected to the connecting frame 6.

[0048] In this embodiment of the application, due to the aforementioned structure, the material is released from the winding drum 3, passes sequentially over the fixed roller 8 and the movable roller 7, and then coats the metal sheet. When too much material is released from the winding drum, the adjusting motor 921 starts, driving the first adjusting gear 922 to rotate. Since the first adjusting gear 922 is meshed with the second adjusting gear 923, the rotation of the first adjusting gear 922 drives the second adjusting gear 923 to rotate, and the rotation of the second adjusting gear 923 drives the rotating block 91 to rotate within the movable cavity 93. The inclined block 94 and the inclined groove 6... Under the action of 3, the rotating block 91 rotates and pushes the adjusting block 62 to slide in the adjusting groove 61, thereby adjusting the distance between the movable roller 7 and the fixed roller 8. When the material wrapped around the movable roller 7 and the fixed roller 8 is in a taut state, the adjusting block 62 continues to slide in the adjusting groove 61. Under the influence of the material resistance, the movable roller 7 stops moving, and the first spring 651 is compressed and contracted until the movable roller 7 contacts the feedback button 652 on the slide 64, and the adjusting motor 921 stops, thereby effectively avoiding material damage caused by the excessive distance between the movable roller 7 and the fixed roller 8.

[0049] During the sliding process of the adjusting block 62, the movable roller 7 is driven to move together by the first spring 651. Before the material is tightened, the movable roller 7 will never contact the feedback button 652 on the chute 64.

[0050] When the material on the winding drum 3 is used up, the adjusting motor 921 starts, and the rotating block 91 is rotated through the first adjusting gear 922 and the second adjusting gear 923 and returned to the initial state. Under the action of the second spring 954, the connecting column 951 and the pressure plate 952 are pushed. The pressure plate 952 pushes the adjusting block 62 to reset. Under the action of the first spring 651, the movable roller 7 is pushed to reset.
