Abstract
Description
Technical Field
[0001] This utility model belongs to the field of insulating board film application technology, and specifically relates to an insulating board film application device. Background Technology
[0002] Existing insulating boards typically require a protective film to be applied to their surface during use to prevent scratches, abrasions, or moisture absorption during transportation, storage, or subsequent processing, which could affect their insulation performance and service life. Traditional film application methods rely heavily on manual labor, where workers manually lay the film onto the insulating board surface and then press it together using simple rollers. This method suffers from low efficiency, significant film waste, and inconsistent application quality. Especially in large-scale processing, manual film application is not only labor-intensive but also prone to defects such as incomplete adhesion, bubbles, and wrinkles, resulting in poor surface protection of the insulating board.
[0003] To address this, some companies have attempted to introduce semi-automatic or simple conveying devices in conjunction with pressure rollers to achieve film application. However, existing equipment often only allows for single-sided film application. If double-sided protection is required, two processing steps are necessary, increasing both the number of steps and labor and time costs. Furthermore, during the film application process, the conveying of the film material and the transmission of the insulating board are often out of sync, easily causing uneven film stretching or misalignment, thus affecting the application effect and even damaging the film material. Utility Model Content
[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide an insulating board film-applying device, which can simultaneously apply film to both sides of the insulating board during the transportation process, improve processing efficiency and ensure film-applying quality.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An insulating board film application device includes a first belt conveyor and a second belt conveyor arranged on the left and right sides. Material racks are provided on both the upper and lower sides of the gap between the first belt conveyor and the second belt conveyor. A column is fixed near the left end of the second belt conveyor, and guide plates that can be adjusted in front and behind are provided on both the front and rear sides of the upper surface of the second belt conveyor. The upper material rack is fixed on the column, and the lower material rack is fixed on the support leg on the left rear side of the second belt conveyor. Film rolls are installed on both the upper and lower material racks.
[0007] Pressure rollers are provided on both the left and right sides of the upper material rack. Both pressure rollers on the left and right sides can be lifted and installed on the column via lifting components. Support rollers are provided on the inner side of the gap between the first belt conveyor and the second belt conveyor, corresponding to the position of the left pressure roller. Fixed frames for rotating and installing the two pressure rollers are provided on the upper side of the two pressure rollers. A drive mechanism for driving the two pressure rollers to rotate simultaneously is fixed on the upper side of the right fixed frame.
[0008] The rear end of the support roller is fixedly connected to the first belt conveyor and the second belt conveyor, and the first belt conveyor and the second belt conveyor are also fixedly connected by a connecting rod on the front side.
[0009] Furthermore, driven pulleys are fixed to the front ends of the central shafts of the two pressure rollers, and first plugs are fixed to the rear sides of the two fixed brackets.
[0010] Furthermore, the lifting assembly includes a guide rod fixed to the side of the column and a lifting rod slidably mounted on the guide rod. The upper end of the column is fixed with a lifting mechanism that drives the lifting rod to move up and down. Both fixing brackets are inserted into the lifting rod through the first plug.
[0011] Furthermore, a first insertion port is provided on the side of the lifting rod, and a first locking screw is installed on the upper side of the lifting rod at the position corresponding to the first insertion port. A slot for engaging with the guide rod is provided on the side of the lifting rod.
[0012] Furthermore, the lifting mechanism includes a fixing plate fixed to the upper end of the column, a screw threaded through the lifting rod is rotatably installed on the lower side of the fixing plate, and a rotating handle is fixed to the upper end of the screw through the fixing plate.
[0013] Furthermore, the drive mechanism includes a motor fixed on a fixed frame, and two drive pulleys are fixed on the output shaft of the motor. The two drive pulleys are respectively connected to the left and right driven pulleys through a first transmission belt and a second transmission belt.
[0014] Furthermore, the material rack includes a crossbar, with a fixed edge fixed at the right end of the crossbar, and a rotating seat fixed at the lower side of the crossbar near the left end. A rotating rod extending forward is rotatably mounted on the rotating seat. The film roll is fitted onto the rotating rod, and both ends of the film roll are provided with retaining rings fitted onto the rotating rod. Adjusting screws are threaded onto the outer side of the retaining rings.
[0015] Furthermore, a support frame is provided on the lower side of the support roller for rotating installation, and a connecting frame is provided on the rear side of the support roller. The left and right ends of the connecting frame are respectively fixed on the support legs on the rear side of the first belt conveyor and the second belt conveyor. A second plug is fixed on the rear side of the support frame, a second socket is opened on the connecting frame, and a second locking screw is installed on the upper side of the connecting frame at the position corresponding to the second socket.
[0016] Furthermore, several mounting plates are fixed on one side of the guide plate. The mounting plates have elongated holes, and locking screws that are fixed to the second belt conveyor are inserted into the elongated holes.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] This invention achieves simultaneous double-sided film application on the insulation board during transport by symmetrically arranging material racks and film rolls on both the upper and lower sides, in conjunction with the combined action of guide plates, pressure rollers, and support rollers. Compared with existing manual or single-sided film application equipment, this structure avoids repetitive processing steps, significantly improves film application efficiency, reduces labor costs, and solves the problem of low processing efficiency in traditional processes.
[0019] This invention utilizes the cooperation of pressure rollers and support rollers, along with the height adjustment function of the lifting assembly, to adjust the pressing pressure according to the thickness of the insulating board, thereby ensuring that the film is evenly adhered to both sides of the insulating board. This design effectively solves the common problems of bubbles, wrinkles, and poor adhesion in manual film application, guaranteeing the quality of film application and improving the surface protection effect of the insulating board.
[0020] This invention uses a drive mechanism to synchronously rotate the pressure rollers, combined with the stable conveyor belt, to achieve synchronous transmission between the insulating board and the film, avoiding problems such as uneven film stretching and misalignment. This method ensures the consistency of the film and the insulating board during operation, solving the problems of film misalignment and damage that easily occur during film supply in existing equipment, thereby ensuring the stability and continuity of film application.

[0031] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0032] Example 1:
[0033] like Figure 1 and Figure 2As shown, an insulating board film-applying device includes a first belt conveyor 1 and a second belt conveyor 7 arranged left and right. Material racks 4 are provided on both the upper and lower sides of the gap between the first belt conveyor 1 and the second belt conveyor 7. The material racks 4 are used to install and support film rolls 3. Continuous film supply from the film rolls 3 ensures continuous film application of the insulating board during the conveying process. A column 5 is fixed near the left end of the second belt conveyor 7. The column 5 not only provides support but also provides installation positions for the pressure roller 2, the fixing frame 22, and the lifting assembly, thus ensuring structural stability. Both the front and rear sides of the upper surface of the conveyor 7 are equipped with guide plates 8 that can be adjusted in front and back. The guide plates 8 limit the lateral displacement of the insulating plate, so that the insulating plate can stably enter between the pressure roller 2 and the support roller 10, thereby avoiding the problem of misalignment between the film and the plate in traditional manual film application. The upper material rack 4 is fixed on the column 5, and the lower material rack 4 is fixed on the support leg on the left rear side of the second belt conveyor 7. Film rolls 3 are installed on both the upper and lower material racks 4. Through the symmetrical arrangement of the upper and lower material racks 4, the film can act on the upper and lower surfaces of the insulating plate at the same time, ensuring the continuity of double-sided synchronous film application.
[0034] Pressure rollers 2 are installed on both the left and right sides of the upper material rack 4. Both pressure rollers 2 are mounted on the column 5 by means of a lifting assembly. The lifting installation method allows the pressure rollers 2 to be adjusted in position according to the insulation board of different thicknesses, ensuring uniformity of film application pressure. Support rollers 10 are installed on the inner side of the gap between the first belt conveyor 1 and the second belt conveyor 7, corresponding to the position of the left pressure roller 2. The support rollers 10 and the pressure rollers 2 work together to apply clamping pressure to the insulation board, so that the film is tightly bonded to the insulation board, thereby solving the problems of loose film application, air bubbles and wrinkles in the traditional film application process. Fixing frames 22 are installed on the upper side of the two pressure rollers 2 to rotate them. The stable installation of the fixing frames 22 ensures the balanced operation of the pressure rollers 2. A drive mechanism 6 is fixed on the upper side of the right fixing frame 22 to drive the two pressure rollers 2 to rotate simultaneously. The drive mechanism 6 drives the transmission belt through the motor 63, thereby ensuring that the two pressure rollers 2 work synchronously and improving the film application efficiency.
[0035] The rear end of the support roller 10 is fixedly connected to the first belt conveyor 1 and the second belt conveyor 7 to form an integral conveying and pressing structure, which ensures the stability of the insulation board under force during the conveying process. The first belt conveyor 1 and the second belt conveyor 7 are also fixedly connected by the connecting rod 9 on the front side. The connecting rod 9 makes the two conveyors form an integral frame, avoiding relative displacement between the two, thereby ensuring the accuracy of the path of the insulation board during the conveying process and improving the stability of the film application process.
[0036] like Figure 2As shown, driven pulleys 21 are fixed at the front ends of the central shafts of the two pressure rollers 2. The driven pulleys 21 cooperate with the driving pulleys 62 to realize the synchronous rotation of the pressure rollers 2, ensuring that the insulating plate is always in a state of balanced force when passing through. The rear sides of the two fixed frames 22 are fixed with first plugs 23. The first plugs 23 cooperate with the lifting components, so that the pressure rollers 2 can be easily installed or disassembled, thereby improving the maintainability and adaptability of the device.
[0037] like Figure 2 As shown, the lifting assembly includes a guide rod 25 fixed to the side of the column 5 and a lifting rod 24 slidably mounted on the guide rod 25. The cooperation between the guide rod 25 and the lifting rod 24 ensures the linear motion accuracy during the lifting process and avoids the offset of the pressure roller 2 during the up and down movement. The upper end of the column 5 is fixed with a lifting mechanism 26 that drives the lifting rod 24 to lift. The lifting mechanism 26 achieves height adjustment accuracy through a screw transmission structure. Both fixing brackets 22 are inserted into the lifting rod 24 through the first plug 23, realizing the stable installation of the pressure roller 2.
[0038] like Figure 3 As shown, a first socket 241 is provided on the side of the lifting rod 24, and a first locking screw 242 is installed on the upper side of the lifting rod 24 at a position corresponding to the first socket 241. The first locking screw 242 is used to lock the position after the height is adjusted to prevent the lifting rod 24 from sliding down. A slot 243 is provided on the side of the lifting rod 24 to engage with the guide rod 25. The slot 243 interacts with the guide rod 25 to further improve the stability of the lifting movement.
[0039] like Figure 4 As shown, the lifting mechanism 26 includes a fixed plate 262 fixed to the upper end of the column 5. A screw 263 threaded through the lifting rod 24 is rotatably installed on the lower side of the fixed plate 262. The screw 263 and the lifting rod 24 are threaded together to achieve lifting adjustment. The upper end of the screw 263 passes through the fixed plate 262 and is fixed with a handle 261. The handle 261 is used for manual rotation operation. The height of the lifting rod 24 can be controlled by simple rotation, thus ensuring the flexibility of the device when adapting to insulation boards of different thicknesses.
[0040] like Figure 5As shown, the drive mechanism 6 includes a motor 63 fixed on the fixed frame 22. Two drive pulleys 62 are fixed on the output shaft of the motor 63. The two drive pulleys 62 are connected to the left and right driven pulleys 21 respectively through the first transmission belt 61 and the second transmission belt 64. The motor 63 drives the first transmission belt 61 and the second transmission belt 64 to drive the left and right driven pulleys 21 to rotate through the drive pulleys 62. This drives the pressure roller 2 to press the insulating board and move it to the left at the same time, realizing the integrated operation of conveying and film application of the insulating board, avoiding the defects of manual pushing or secondary processing required in traditional processes.
[0041] like Figure 6 As shown, the material rack 4 includes a crossbar 42, with a fixed edge 41 fixed to the right end of the crossbar 42, which serves as a support and limiting element. A rotating seat 43 is fixed to the lower side of the crossbar 42 near the left end, and a rotating rod 44 extending forward is rotatably mounted on the rotating seat 43. The film roll 3 is fitted onto the rotating rod 44, and both ends of the film roll 3 are provided with retaining rings 46 fitted onto the rotating rod 44. Adjusting screws 45 are threaded onto the outer side of the retaining rings 46. The position of the retaining rings 46 can be adjusted by adjusting the screws 45, thereby limiting and fixing the film roll 3, preventing positional deviation of the film roll 3 during rotation, and ensuring the stability of the film supply process. The retaining rings 46 on both sides, in cooperation with the adjusting screws 45, can also adapt to film rolls 3 of different widths, improving the versatility of the device.
[0042] like Figure 7 As shown, a support frame 101 is provided on the lower side of the support roller 10 for rotatable mounting, and the support frame 101 provides a fulcrum for the rotation of the support roller 10; a connecting frame 104 is provided on the rear side of the support roller 10, and the left and right ends of the connecting frame 104 are respectively fixed on the support legs on the rear side of the first belt conveyor 1 and the second belt conveyor 7, ensuring the installation stability of the support roller 10; a second plug 105 is fixed on the rear side of the support frame 101, and a second socket 103 is provided on the connecting frame 104, and a second locking screw 102 is installed on the upper side of the connecting frame 104 at the position corresponding to the second socket 103. Through the cooperation of the socket and the locking screw, the support roller 10 can be easily disassembled and replaced, improving the maintainability and assembly flexibility of the structure.
[0043] like Figure 8 As shown, several mounting plates 81 are fixed on one side of the guide plate 8. The mounting plates 81 have elongated holes 83. Locking screws 82 fixed on the second belt conveyor 7 are inserted into the elongated holes 83. The locking screws 82 can move the guide plate 8 back and forth by adjusting their position in the elongated holes 83, which ensures that the insulating board can stably enter the film application station under different specifications, thereby solving the problem of poor film application accuracy caused by inconsistent board size in traditional manual film application.
[0044] Example 2:
[0045] See Figures 1-8 The operation process of an insulating board film application device is as follows:
[0046] In use, the operator first installs the upper and lower film rolls 3 on the upper material rack 4 on the column 5 and the lower material rack 4 on the left rear support leg of the second belt conveyor 7, respectively. The film rolls 3 are rotated and supported by the rotating rod 44, and their positions are limited and adjusted by the retaining ring 46 and the adjusting screw 45, so as to ensure that the film rolls 3 can maintain stable material supply during operation. Then the operator pulls out the front end of the upper and lower film rolls 3, and uses tape to connect the film ends to ensure that the film is synchronously attached to both sides of the insulation board.
[0047] When the device is started, the motor 63 drives the first transmission belt 61 and the second transmission belt 64 to rotate through the drive pulley 62 on the output shaft, thereby driving the driven pulley 21 fixed at the front end of the central shaft of the pressure roller 2 to rotate synchronously, so that the left and right pressure rollers 2 rotate simultaneously under the rotational installation of the fixed frame 22; at this time, the second belt conveyor 7 starts to operate under the drive of the motor, moving the insulating board to be coated to the left along the conveying direction. During the conveying process, the guide plate 8 adjusts its front and rear positions through the mounting plate 81 and the elongated hole 83 in conjunction with the locking screw 82, thereby limiting and guiding the insulating board and preventing the insulating board from shifting laterally during conveying.
[0048] When the insulating plate reaches the right pressure roller 2, the right pressure roller 2 and the second belt conveyor 7 continue to convey the insulating plate to the left. At the same time, the left end of the insulating plate is close to the front end of the film pulled out by the film roll 3 and continues to move with the conveying direction. At this time, the insulating plate drives the film to pull to the left, and the film roll 3 continues to rotate under the support of the rotating rod 44 and the rotating seat 43, thereby realizing the continuous supply of film material.
[0049] When the insulating board enters between the left pressure roller 2 and the support roller 10, the support roller 10 rotates smoothly on the support frame 101. The left pressure roller 2, driven by the drive mechanism 6, cooperates with the support roller 10 to apply uniform clamping pressure to the insulating board and the films on both sides, so that the films are tightly attached to the upper and lower sides of the insulating board. During this process, the guide rod 25 and the lifting rod 24 in the lifting assembly are height-adjusted under the action of the lifting mechanism 26. The operator rotates the handle 261 to drive the screw 263 to rotate, so that the lifting rod 24 moves up and down along the guide rod 25 and is locked in position through the first socket 241 and the first locking screw 242, thereby ensuring that the pressure roller 2 can be precisely adjusted according to the thickness of the insulating board, avoiding the phenomenon of loose film application or excessive pressing.
[0050] The laminated insulating boards continue to be conveyed to the left by the first belt conveyor 1, ensuring that the laminated insulating boards can be smoothly output to subsequent workstations or stacking areas. When conveyed to the leftmost end, the operator uses a manual blade to cut the continuous film, thereby separating the film from the individual insulating boards. The entire process achieves automatic lamination of both sides of the insulating boards during conveying, avoiding the problems of low efficiency and unstable quality of traditional manual lamination. At the same time, it ensures synchronous conveying and firm adhesion of the film and the insulating board, effectively improving processing efficiency and product quality.
[0051] The working principle of this utility model is as follows: When processing the insulating board with film, the film on the upper and lower film rolls 3 is pulled out and joined together with adhesive tape. Then, the insulating board is placed on the second belt conveyor 7. At this time, the second belt conveyor 7 transports the insulating board to the left. When the insulating board reaches the right pressure roller 2, the right pressure roller 2 cooperates with the second belt conveyor 7 to continue transporting the insulating board to the left. At this time, the left side of the insulating board is pressed against the film and continues to move to the left. At this time, the insulating board and the film together enter between the left pressure roller 2 and the support roller 10. The two rollers, in conjunction with the support roller 10, convey the insulating board to the left and send it to the first belt conveyor 1. At the same time, under the rolling pressure of the left pressure roller 2 and the support roller 10, the film is tightly adhered to the upper and lower sides of the insulating board. The insulating board with the film attached continues to be conveyed to the left on the first belt conveyor 1, while the insulating board on the right side without film attached moves to the left and is attached to the film in turn. The film rolls 3 on the upper and lower sides rotate continuously under the drag of the insulating board to continuously supply material. When the insulating board with the film attached reaches the leftmost side, it is manually cut with a blade, thereby completing the double-sided film application process of the insulating board.
[0052] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
