A protective film application device for roll and sheet materials.

Abstract

This utility model discloses a protective film application device for roll and sheet materials, including a frame on which a film feeding roller and a pressing and bonding component are mounted. The protective film is bonded to one side of the material. The pressing and bonding component applies pressure to the protective film and the material to make the protective film adhere firmly to the material. The frame also includes a bending component. The bending component first applies a force to the portion of the protective film exceeding the width of the material, rotating it towards the bonding surface. Then, it applies a force to the bent protective film, causing it to move towards the side of the material where the protective film is not bonded, ultimately bonding the bent protective film to the material. This solution, by using a bending component and two bending modules (bending module one and bending module two), enables direct use of the protective film exceeding the width of the material. This solves the problem of needing separate processing and provides protection for the other side of the material.

Description

Technical Field

[0001] This utility model belongs to the technical field of film application equipment, and in particular relates to a protective film application equipment for roll materials and sheet materials. Background Technology

[0002] Some coils and sheets are affected by their characteristics, such as being easily corroded or having low surface strength, so they need to be coated with a protective film before leaving the factory. Taking aluminum coils as an example, because aluminum has low strength, aluminum materials need to be coated with a film after processing and production to avoid the problem of the aluminum plate surface being easily scratched.

[0003] In existing technologies, some roll materials or sheets are usually applied on one side only. In order to ensure the application effect, the width of the protective film needs to be greater than the width of the roll material or sheet material. Under this condition, the roll material and the protective film are bonded together. After being pressed and bonded by rollers, the excess protective film is cut off by a cutter to prevent it from sticking to other objects.

[0004] The protective film cut off in the above solution cannot be reused and needs to be processed separately. This not only wastes resources but also increases costs. Therefore, the applicant designed a device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a protective film application device for roll and sheet materials to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a protective film application device for roll and sheet materials, comprising a frame, on which a film feeding roller and a pressing and bonding assembly are installed, the protective film is bonded to one side of the material, and the pressing and bonding assembly applies a squeezing force to the protective film and the material to make the protective film adhere tightly to the material; The frame is also equipped with a bending assembly, which includes a bending module one and a bending module two. The bending module applies a rotational force toward the adhesive surface of the protective film to the portion of the protective film that exceeds the width of the material, and the angle between the folded protective film and the protective film adhered to the material is no greater than 90 degrees. The second bending module is used to apply a force to the protective film after bending by the first bending module, causing it to move toward the side of the material where the protective film is not adhered, and ultimately causing the protective film after bending by the first bending module to adhere to the material.

[0007] Preferably, the material is set horizontally and the protective film is attached to the top surface of the material. The bending module is a vertical cylindrical roller. The portion of the protective film that exceeds the width of the material passes through the gap between the vertical cylindrical roller and the material. The bending module two includes a vertical conical roller and a vertical cylindrical roller two. The protective film, after being bent by the vertical cylindrical roller one, passes between the conical surface of the vertical conical roller and the material, and then passes through the gap between the top surface of the vertical cylindrical roller two and the material.

[0008] Preferably, there are two of each of the vertical cylindrical roller one, the vertical conical roller and the vertical cylindrical roller two.

[0009] Preferably, the frame is equipped with an mounting plate, and the mounting plate is equipped with several adjusting grooves. The two vertical cylindrical rollers, the two vertical conical rollers, and the two vertical cylindrical rollers can all adjust their spacing within the adjusting grooves and are respectively fixed by a fixing component.

[0010] Preferably, the surfaces of the vertical cylindrical roller one, the vertical conical roller and the vertical cylindrical roller two that contact the protective film are made of elastic material.

[0011] Preferably, the frame is also equipped with a second pressing and bonding component, which includes two pressing and bonding rollers. The material and protective film after being processed by the vertical cylindrical roller are pressed together by the two pressing and bonding rollers.

[0012] Preferably, the frame is provided with a mounting frame, one of the pressing rollers is rotatably connected to the mounting frame, and the other pressing roller slides on the mounting frame and moves closer to or away from the other pressing roller. The mounting frame is provided with a fixing member to prevent the pressing roller from sliding freely on the mounting frame.

[0013] Preferably, the pressing assembly includes an active pressing roller and a driven pressing roller disposed on the frame, and the frame is further provided with a drive assembly for controlling the rotation of the active pressing roller.

[0014] Preferably, the frame is further provided with a lifting assembly for controlling the lifting and lowering of the driven pressure roller.

[0015] Preferably, the protective film includes an adhesive film and a separator film, and the frame is provided with a receiving roller for receiving the separator film and a drive assembly for controlling the rotation of the receiving roller.

[0016] The beneficial effects of this utility model are as follows: By setting up a bending component, this solution achieves the direct use of the protective film for the part that exceeds the width of the material through two bending processes, namely bending module one and bending module two. Firstly, it solves the problem of needing to process it separately, and secondly, it provides protection for the other side of the material. The protective film, under the influence of gravity, will naturally bend and fall (either completely or in a bent position) as the portion exceeding the width of the material. A pair of vertical cylindrical rollers guides this bent or completely falling portion, ensuring that this part of the protective film falls vertically. Subsequently, a vertical conical roller lifts the protective film, and finally, the protective film adheres to the material in the gap between the top surface of the vertical cylindrical roller and the material surface. These three steps, which gradually change the angle, make the entire bending process of this part of the protective film stable and effectively ensure the adhesion effect of this part of the protective film. By enabling the spacing of the two vertical cylindrical rollers, the two vertical conical rollers, and the two vertical cylindrical rollers to be adjusted within the adjustment groove, this equipment can be used to bond more specifications of materials and protective films. In order to ensure the adhesion between the protective film and the material, the optimal solution during the production and assembly of this equipment is that the gap between the vertical cylindrical roller, the vertical conical roller and the vertical cylindrical roller during operation is no greater than the thickness of the protective film. By setting the contact surface with the protective film to be an elastic material, the degree of deformation caused by the material to adhere to the material can be reduced, resulting in a better adhesion effect. The second pressing component further presses the protective film to ensure that it does not easily detach from the material. The lifting assembly is used to facilitate the initial adhesion and entry of materials and protective film. Attached Figure Description

[0018] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0019] Example: In this embodiment, the protective film used by the device includes two layers. The first layer is an adhesive film 4 with one side being self-adhesive, and the second layer is a separator film 5 that prevents the two layers of the rolled protective film from sticking together. Of course, in other embodiments of the device, such as those in which adhesive is sprayed between the material 6 and the protective film before they are bonded, the structure of bending the film in this solution can still be protected. In this solution, the material 6 refers to metal rolls or sheets.

[0020] See Figure 1-4 A protective film application device for roll and sheet materials includes a frame 1. A film feeding roller 3 and a pressing and bonding assembly 2 are mounted on the frame 1. The protective film is bonded to one side of a material 6. The pressing and bonding assembly 2 applies pressure to the protective film and the material 6 to ensure the protective film adheres firmly to the material 6. In this embodiment, the pressing and bonding assembly 2 includes an active pressure roller 21 and a driven pressure roller 22 mounted on the frame 1. The frame 1 also includes a drive assembly 12 for controlling the rotation of the active pressure roller 21. The drive assembly 12 can be a motor, such as... Figure 1 As shown, the drive assembly 12 can be housed in a box and control the rotation of the active pressure roller 21; Among them, participants Figure 3The frame 1 is also equipped with a lifting assembly 13 for controlling the lifting of the driven pressure roller 22. Specifically, the lifting assembly 13 can be two cylinders fixed on the frame 1. The two ends of the driving pressure roller 21 are respectively rotatably connected to a bearing seat 211. The bearing seat 211 is fixed on the frame 1. The working end of each lifting assembly 13 is fixed with a bearing seat 222. The two ends of the driven pressure roller 22 are respectively rotatably connected to the two bearing seats 222.

[0021] The frame 1 is also provided with a bending assembly, which includes a bending module 7 and a bending module 8. The bending module 7 applies a rotational force toward the adhesive surface of the protective film that extends beyond the width of the material 6, and the angle between the folded protective film and the protective film adhered to the material 6 is no greater than 90 degrees. The bending module 2 8 is used to apply a force to the protective film after bending by the bending module 1 7, causing it to move toward the side of the material 6 where the protective film is not adhered, and ultimately causing the protective film after bending by the bending module 1 7 to adhere to the material 6.

[0022] Among them, see Figure 1 , Figure 2 , Figure 4 The material 6 is set horizontally and the protective film is attached to the top surface of the material 6. The bending module 7 is a vertical cylindrical roller 71. The portion of the protective film that exceeds the width of the material 6 passes through the gap between the vertical cylindrical roller 71 and the material 6. The bending module 2 8 includes a vertical conical roller 81 and a vertical cylindrical roller 2 82. The protective film, after being bent by the vertical cylindrical roller 1 71, passes between the conical surface of the vertical conical roller 81 and the material 6, and then passes through the gap between the top surface of the vertical cylindrical roller 2 82 and the material 6.

[0023] Each of the vertical cylindrical roller 71, the vertical conical roller 81, and the vertical cylindrical roller 82 is provided in twos.

[0024] The frame 1 is equipped with an mounting plate 11, which has several adjusting grooves 111. The two vertical cylindrical rollers 71, two vertical conical rollers 81, and two vertical cylindrical rollers 82 can all have their spacing adjusted within the adjusting grooves 111 and are respectively fixed by a fixing component. Specifically, the vertical cylindrical rollers 71, 81, and 82 are respectively mounted on a fixed rotating shaft 711, a fixed rotating shaft 811, and a fixed rotating shaft 822, and the vertical cylindrical rollers 71, 81, and 82 are respectively connected to the fixed rotating shafts. A bearing exists between the first fixed shaft 711, the second fixed shaft 811, and the third fixed shaft 822 to ensure that the first vertical cylindrical roller 71, the first vertical conical roller 81, and the second vertical cylindrical roller 82 can rotate freely. The positions of the first fixed shaft 711, the second fixed shaft 811, and the third fixed shaft 822 can be adjusted within the adjustment groove. The first fixed shaft 711, the second fixed shaft 811, and the third fixed shaft 822 can be tubes, with a long bolt passing through the adjustment groove 111 inserted inside. The long bolt can be used to fix the first fixed shaft 711, the second fixed shaft 811, and the fixed shaft onto the mounting plate 11.

[0025] The surfaces of the vertical cylindrical roller 71, the vertical conical roller 81, and the vertical cylindrical roller 82 that contact the protective film are made of elastic material.

[0026] Among them, see Figure 1 , Figure 4 , Figure 5 The frame 1 is also equipped with a pressing and bonding assembly 9, which includes two pressing and bonding rollers 91. The material 6 and the protective film, after being processed by the vertical cylindrical roller 82, are pressed together by the two pressing and bonding rollers 91.

[0027] Among them, see Figure 4 , Figure 5 The frame 1 is provided with a mounting frame 92 (in this embodiment, the mounting frame 92 is fixed on the mounting plate 11). One pressing roller 91 is rotatably connected to the mounting frame 92, and the other pressing roller 91 slides on the mounting frame 92 and moves closer to or further away from the other pressing roller 91. The mounting frame 92 is provided with a fixing member to prevent the pressing roller 91 from sliding freely on the mounting frame 92. Specifically, the two pressing rollers 91 are respectively rotatably connected to a rotating shaft (not labeled), and their positions are fixed in the axial direction of the rotating shaft. Two plates are fixed on the mounting plate 11. Rotating holes are provided on the plates so that the rotating shaft can be rotatably connected in the two rotating holes. Fixing holes 922 are also provided on the plates, which are threaded holes. Insertion holes (not marked) are provided at both ends of the rotating shaft. When the rotating shaft is placed in the rotating hole, the fixing hole 922 can communicate with the insertion hole. The rotating shaft can be fixed on the plate by inserting a fixing bolt 94 into the fixing hole 922 and into the insertion hole. The two plates are provided with grooves 921. The two ends of the shaft of the other pressing roller 91 move up and down in the grooves 921. Each end of the shaft has a second insertion hole (not marked). After the shaft is put into the grooves 921, the two second insertion holes are respectively placed on the opposite outer sides of the two plates of the mounting frame 92. Limiting pins 95 are inserted into the second insertion holes to fix the axial position of the shaft in the grooves 921. Specifically, the limiting pins 95 can be R-type pins. After being inserted into the second insertion holes, they fit against the outer wall of the plates of the mounting frame 92 and will not fall into the grooves. The mounting bracket 92 has a threaded adjustment hole 923 extending to the slide groove 921. The direction of the threaded adjustment hole 923 is the same as the direction of the sliding shaft within the slide groove 921. An adjustment bolt 93 is threaded onto the threaded adjustment hole 923. By the contact between the end of the adjustment bolt 93 and the rotating shaft, the two adhesive rollers cannot move away from each other. The adjustment bolt 93 is designed to allow materials of different thicknesses 6 to pass between the two adhesive rollers.

[0028] Among them, see Figure 1 , Figure 2 The protective film includes an adhesive film 4 and a separator film 5. The frame 1 is provided with a receiving roller 10 for receiving the separator film 5 and a second drive assembly 14 for controlling the rotation of the receiving roller 10. The second drive assembly 14 can be a motor.

[0029] Working principle and process: When using the product of this solution, the rolled protective film is placed on the film feeding roller 3, and at the same time, the lifting component 13 controls the driven pressure roller 22 to rise. The material 6 is fed into the space between the active pressure roller 21 and the driven pressure roller 22 through its own feeding mechanism. The protective film is peeled off, and the separating film 5 is rolled onto the take-up roller 10. The adhesive is then attached to the material 6. Subsequently, the protective film and the material 6 at the ends can be manually adjusted to pass through the vertical cylindrical roller 71, the vertical conical roller 81 and the vertical cylindrical roller 82. Then, the lifting component 13 controls the driven pressure roller 22 to descend, thereby pressing the protective film and the material 6 together. The material 6 moves forward under its rotation, thus achieving the attachment of the protective film to the material 6.

Any equivalent structural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
