Description

Technical Field

[0001] This utility model relates to the technical field of film application devices, specifically a film application device for sign production. Background Technology

[0002] During the production and processing of signs, a film-applying device is needed to affix the printed patterns and text to the surface of the signs for display, or to apply various protective films to the surface of the signs for protection. For signs produced in batches, the film-applying device can quickly apply film to the signs by conveying them in a row through a conveyor mechanism.

[0003] The utility model patent with authorization announcement number "CN 220973343 U" discloses a film-applying device for sign production. It can use a blade to cut off the excess film from the edges of the sign after it has been applied. However, the existing film-applying device for sign production has a relatively simple structure. It only moves the sign by conveyor belt, and the moving sign moves the film together. During the movement, the sign may be displaced relative to the conveyor belt due to the force of the rolled film or the obstruction of the bending limiting plate, which changes the forward speed of the sign. As a result, the cutting mechanism cannot accurately judge the position of the sign and is prone to accidentally cutting the sign. Therefore, a film-applying device for sign production is proposed to address the above problems. Utility Model Content

This prevents the sign from being displaced relative to the conveyor belt body of the conveyor belt assembly due to the force of the rolled film, thus ensuring the accurate cutting position of the device and avoiding damage to the sign.

[0018] A cutting assembly 6 is provided on the upper side of the workbench 1. The cutting assembly 6 includes a fixed frame 61 located to the right of the second limiting shaft 35 and fixedly connected to the upper end face of the workbench 1. A pair of third cylinders 62 are fixedly connected to the lower side of the first frame of the fixed frame 61. A first cutting blade 63 is fixedly connected to the piston rod of the pair of third cylinders 62 on the lower side of the first frame of the fixed frame 61. A pair of symmetrically distributed fixed plates 64 are provided on the right side of the fixed frame 61 and fixedly connected to the upper end face of the workbench 1. A fourth cylinder 65 is fixedly connected to the opposite side of the two fixed plates 64. A second cutting blade 66 is fixedly connected to the piston rod of each of the fourth cylinders 65. The first cutting blade 63 and the second cutting blade 66 can be used to cut the film at the left and right ends and the front and rear ends of the sign, respectively. The first limiting shaft 31 located on the rear side is fixedly connected to the upper end face of the workbench 1, and the first limiting shaft 31 located on the front side is detachably connected to the upper end face of the workbench 1. The first limiting shaft 31 can limit the film-applying roller 32; the drive assembly 4 located on the left side is set to the left of the first limiting shaft 31, and the drive assembly 4 located on the right side is set between the second limiting shaft 35 and the fixing frame 61. The two drive assemblies 4 can stably drive the film-applied signs to move; the support frame 42 and the fixing frame 61 are both inverted "U" shaped bending frames, and the two bending limiting plates 52 are symmetrically distributed front and back. The lower ends of the bending limiting plates 52 are in contact with the conveyor belt body of the conveyor belt assembly 2. The bending limiting plates 52 can make the signs neatly arranged; the conveyor belt assembly 2 consists of a shell, a drive shaft, a driven shaft, a motor, a conveyor belt body and a support plate. The support plate of the conveyor belt assembly 2 is fixedly connected inside the shell. The upper surface of the support plate of the conveyor belt assembly 2 is in contact with the upper inner wall of the conveyor belt body. The support plate of the conveyor belt assembly 2 can prevent the conveyor belt body from becoming loose due to the force of pressing the drive roller 47.

[0019] Workflow: Before use, install the workbench 1 in a suitable position and connect the power supply to the device. The device is equipped with an external controller, which is electrically connected to the conveyor belt assembly 2, the first cylinder 41, the drive motor 48, the second cylinder 51, the third cylinder 62, and the fourth cylinder 65. Manual operation of the external controller can adjust the operating status of the conveyor belt assembly 2, the first cylinder 41, the drive motor 48, the second cylinder 51, the third cylinder 62, and the fourth cylinder 65 respectively. All of the above are existing technologies. When using the device, the operator first removes the first limiting shaft 31 located on the front side, removes the film application roller 32, loosens the locking bolt 34, removes the bonding positioning plate 33 from the film application roller 32, and puts the rolled film onto the... The film is mounted on the film mounting roller 32 and positioned approximately in the middle. Then, the bonding positioning plates 33 are fitted onto the film mounting roller 32, ensuring that the opposing sides of the two bonding positioning plates 33 and the two ends of the rolled film are tightly bonded. Tightening the locking bolts 34 locks the rolled film in place. Due to the clamping of the bonding positioning plates 33, the rolled film cannot rotate relative to the film mounting roller 32. The film mounting roller 32 is then remounted between the two first limiting shafts 31, and the first limiting shaft 31 located at the front is fixed to the worktable 1. This completes the film installation. Subsequently, the operator uses an external controller to adjust the extension lengths of the paired second cylinders 51 and the paired fourth cylinders 65, ensuring that the distance between the two bending limiting plates 52 is equal to the marked distance. The pre-adjustment is completed when the length of the sign in the front-to-back direction is equal to the distance between the two second cutting blades 66. Then, the operator adjusts the extension length of the two pairs of first cylinders 41 via an external controller. This causes the support frame 42 to move up and down, compressing both pairs of compression springs 46. This unfolds the rolled film end and passes it under the film support roller 36, which is limited by the second limiting shaft 35, thus affixing it to a sign. Multiple signs are then laid on the upper side of the conveyor belt of the conveyor belt assembly 2, ensuring the left and right ends of the signs are in contact. Next, the operator starts the conveyor belt assembly 2 and the two drive motors 48 simultaneously via the external controller, which maintains them at the same linear speed. At this point, the staff only needs to place multiple signs sequentially on the conveyor belt body of the conveyor belt assembly 2, ensuring that the left and right ends of the signs are in contact with each other. The conveyor belt assembly 2 will then move the signs from left to right. Compression springs 46 located within the first limiting sleeve 43 and the second limiting sleeve 45 apply a downward force to the limiting seat 44, causing the pressing drive roller 47 to press the signs down. The drive motor 48 drives the pressing drive roller 47 to rotate, thus moving the signs. Because the conveyor belt assembly 2 is equipped with a support plate, the conveyor belt body of the conveyor belt assembly 2, supported by the support plate, can work with the pressing drive roller 47 to clamp the signs, thereby ensuring stable movement of the signs from left to right.The device is equipped with two pressing drive rollers 47. The pressing drive roller 47 located to the left of the first limiting shaft 31 can drive the movement of unfilmed signs, while the pressing drive roller 47 located between the second limiting shaft 35 and the fixing frame 61 can drive the movement of filmed signs. This effectively prevents the signs from shifting relative to the conveyor belt due to the force of the rolled film application, ensuring a constant forward speed for the signs. The external controller can determine the time interval for the third cylinder 62 to extend downwards based on the sign's moving speed and its lateral width, thus accurately cutting the film at the junction of two adjacent signs. The device uses the spring force of the compression spring 46 to exert a downward force on the limiting seat 44. The pressing drive roller 47, limited by the limiting seat 44, presses the signs. The drive motor 48 drives the pressing drive roller 47 to rotate, thereby driving the signs to move at a constant speed. This prevents the signs from shifting relative to the conveyor belt body of the conveyor belt assembly 2 due to the force of the rolled film application, ensuring accurate cutting and preventing damage to the signs.
