Description

Technical Field

[0001] This utility model relates to the field of semi-automatic film applicator technology, and in particular to a roller-type semi-automatic film applicator. Background Technology

[0002] Semi-automatic film applicators are mechanical devices used in industrial production and daily life to apply protective films to the surface of objects. They complete the film conveying, positioning, and applicating operations by combining mechanical transmission with manual assistance. Compared with completely manual film applicator, they can improve the film applicator efficiency.

[0003] As a type of semi-automatic laminating machine, the core of the roller-type semi-automatic laminating machine lies in using the roller component to apply pressure to the film. Through the rolling action, the film is evenly adhered to the surface of the target object. The operator first places the object to be laminated on the positioning platform, then manually pulls the film out from the unwinding mechanism and covers the surface of the object. The roller device is then started, and the roller component rolls along the surface of the film, tightly adhering the film to the object.

[0004] Traditional semi-automatic roll laminating machines suffer from uneven wear on different parts of the rollers after prolonged use. This leads to uneven stress on the film material during transport, causing unstable tension and wrinkles that affect lamination quality. Existing technologies stabilize film transport tension and ensure lamination quality by incorporating tension adjustment mechanisms and using wear-resistant rollers. However, in actual use, when changing the film, operators need to dismantle multiple complex fastening devices used to secure the film roll. This dismantling and installation process is time-consuming, reducing equipment efficiency and increasing production costs. Utility Model Content

This realizes the function of real-time and accurate detection and correction of film material deviation, effectively improving the problem of easy film material deviation in the prior art, ensuring stable film material transmission, improving film application quality and production efficiency, and reducing the defect rate.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of a semi-automatic film applicator, comprising a base 1 for supporting all components of the applicator, a film applicator assembly on the top of the base 1 for implementing the film applicator operation, a housing 7 fixedly connected to the left side of the base 1 for protecting internal electrical components and providing an installation location, a film feeding roller 9 rotatably connected to the rear right side of the housing 7 for carrying and conveying film material, a transmission gear 10 fixedly connected to the left side of the film feeding roller 9 through the right side of the housing 7 for transmitting power, and a servo motor 11 fixedly connected to the bottom of the inner wall of the housing 7 for providing power for the rotation of the film feeding roller 9. The power source is a servo motor 11, whose output end is fixedly connected to a drive gear 12. The drive gear 12 cooperates with the transmission gear 10 to drive the film feeding roll 9 to rotate. The outer walls of both the drive gear 12 and the transmission gear 10 are meshed with the same track 13, which transmits power to rotate the transmission gear 10. The inner wall of the film feeding roll 9 has a groove 14, which provides sliding space for the slider 16. Hydraulic rods 15 are fixedly connected to the left and right sides of the inner wall of the groove 14. The hydraulic rods 15 can push the slider 16 to move within the groove 14. Multiple sliders 16 are slidably connected to the inner wall of the groove 14. The sliders 16 can slide within the groove 14 to adjust the position of the film feeding roll 20. U-shaped blocks 17 are fixedly connected to all four sides of the outer wall. These U-shaped blocks 17 connect to and allow the moving rods 18 to rotate. The inner walls of multiple U-shaped blocks 17 are rotatably connected to the moving rods 18, which can rotate within the U-shaped blocks 17 to adapt to different operational needs. The tops of the multiple moving rods 18 are rotatably connected to corresponding top plates 19, which support the film feeding roll 20. The opposite sides of the left and right sliders 16 are fixedly connected to adjacent ends of corresponding hydraulic rods 15. The position of the film feeding roll 20 is adjusted by pushing the sliders 16 through the hydraulic rods 15. The outer walls of multiple top plates 19 are each equipped with the same film feeding roll 20, which is used to wind the film material. The film application assembly includes a sliding... The film application platform 3 provides a platform for placing and moving objects to be filmed. The bottom of the sliding film application platform 3 is fixedly connected to the top front side of the base 1. A fixing rod 4 is fixedly connected to the right front end of the machine box 7. The fixing rod 4 is used to fix the lifting component 5. The bottom of the fixing rod 4 is fixedly connected to the lifting component 5. The lifting component 5 can adjust the height of the roller head 6. The bottom of the lifting component 5 is rotatably connected to the roller head 6. The roller head 6 is used to roll and apply the film material to the object. A film cutting machine 8 is fixedly connected to the right bottom of the machine box 7. The film cutting machine 8 is used to cut the film material. An automatic correction mechanism 2 is set on the top of the base 1. The automatic correction mechanism 2 is used to automatically correct the deviation of the film material when it is offset, thereby ensuring the accuracy and quality of film application.

[0035] Specifically, when using the film applicator, during operation, the servo motor 11 is first turned on. The output of the servo motor 11 drives the drive gear 12 to rotate. Since the drive gear 12 and the transmission gear 10 are connected by the track 13, the transmission gear 10 rotates accordingly, which in turn drives the film feeding roller 9 to rotate. The hydraulic rod 15 plays a key role in the groove 14 on the inner wall of the film feeding roller 9. When the film feeding roller 20 needs to be replaced, the hydraulic rod 15 shortens, pulling the sliders 16 on both sides to slide in the groove 14, causing multiple U-shaped blocks 17 connected to the moving rod 18 to move inward. The top plate 19 at the top of the moving rod 18 then retracts, and the film feeding roller 20 can be easily removed. When installing a new film feeding roller 20, the hydraulic rod 15 extends, and the top plate... 19 spreads outwards, firmly fixing the film feeding roll 20. This design greatly simplifies the film changing process and saves time. The film material on the film feeding roll 20 is fed out by the rotation of the film feeding roll 9, passes above the film cutting machine 8, and when the film material reaches above the sliding film application platform 3, the lifting component 5 is activated. The lifting component 5 drives the roller head 6 to descend. The roller head 6 rotates and rolls on the film material, tightly adhering the film material to the surface of the item placed on the sliding film application platform 3. When the film application is completed to a certain length, the film cutting machine 8 is activated to cut the film material, completing one film application process. Throughout the process, through ingenious structural design, not only is a semi-automatic film application function realized, but more importantly, the problem of complex film changing is solved, improving equipment production efficiency and reducing production costs.

[0036] Reference Figure 1 , Figure 2 and Figure 3The automatic alignment mechanism 2 includes a rotating shaft 201, which serves as a support shaft for the rotation of the connecting frame 202. The bottom of the rotating shaft 201 is fixedly connected to the top of the base 1, thus securing the automatic alignment mechanism 2 to the base 1. The connecting frame 202 is rotatably connected to the top of the rotating shaft 201. The connecting frame 202 supports the horizontal shaft 203 and the guide roller 204 and can rotate around the rotating shaft 201 to adjust the angle of the guide roller 204. The horizontal shaft 203 is fixedly connected to the top of the connecting frame 202, providing rotational support for the guide roller 204. The guide roller 204 is rotatably connected to the outer wall of the horizontal shaft 203. The guide roller 204 guides the film material and applies lateral force to the film material during rotation for alignment. The rear side of the connecting frame 202 is fixedly connected to... There is a transmission half gear 205, which transmits power by meshing with the drive gear 207, driving the connecting frame 202 to rotate. A servo motor 206 is fixedly connected to the top rear side of the base 1. The servo motor 206 serves as a power source to provide power for the operation of the automatic correction mechanism 2. The output end of the servo motor 206 is fixedly connected to the drive gear 207. The drive gear 207 transmits the power of the servo motor 206 to the transmission half gear 205. The drive gear 207 meshes with the transmission half gear 205 to realize the power transmission and make the connecting frame 202 rotate. A light path sensor 208 is fixedly connected to the top right side of the housing 7. The light path sensor 208 is used to detect whether the membrane material is offset and transmit the signal to the control system.

[0037] Specifically, when the membrane material deviates and automatic correction is required, the membrane material first passes through the guide roller 204 during transport. The guide roller 204 is mounted on the horizontal shaft 203, which is connected to the rotating shaft 201 via the connecting frame 202. The bottom of the rotating shaft 201 is fixed to the top of the base 1, allowing the guide roller 204 to rotate flexibly, providing support and guidance for the membrane material transport. The output end of the servo motor 206 is connected to the drive gear 207, which meshes with the transmission half gear 205 on the rear side of the connecting frame 202. When the servo motor 206 starts, the drive gear 207 rotates. Due to the meshing relationship between the drive gear 207 and the transmission half gear 205, the transmission half gear 205 drives the connecting frame 202 to rotate around the rotating shaft 201. The rotation of the connecting frame 202 changes the angle of the guide roller 204. When the membrane material deviates to the left... When the film shifts, the optical path sensor 208 on the top right side of the chassis 7 senses the shift and transmits a signal to the control system, activating the servo motor 206 on the rear side of the base 1. This motor drives the drive gear 207 to rotate the transmission half gear 205, causing the connecting frame 202 to rotate counterclockwise around the rotating shaft 201. The guide roller 204 tilts to the right, applying a force to the right to correct the film material's deviation. When the film material deviates to the right, the optical path sensor 208 transmits a signal, the servo motor 206 reverses, the drive gear 207 drives the transmission half gear 205 to rotate in the opposite direction, the connecting frame 202 rotates clockwise, and the guide roller 204 tilts to the left, applying a force to the left to correct the deviation. The automatic correction mechanism 2 can promptly detect and effectively solve the problem of film material deviation during the conveying process, ensuring that the film material always maintains an accurate position during the film application process, improving the quality and stability of the film application, avoiding poor film application caused by film material deviation, and improving the overall efficiency and reliability of the film application machine.

[0038] Reference Figure 1 , Figure 6 and Figure 7A maintenance door 21 is rotatably connected to the front left side of the chassis 7. The maintenance door 21 is used to open the interior of the chassis 7 for easy inspection and maintenance of the components inside. A handle 22 is fixedly connected to the rear left side of the maintenance door 21. The handle 22 is easy for the operator to grip and open and close the maintenance door 21. An observation slot 23 is provided on the left side of the chassis 7. The observation slot 23 provides the operator with a window to observe the internal operation of the chassis 7. A transparent plate 24 is fixedly connected to the inner wall of the observation slot 23. The transparent plate 24 can both ensure observation and prevent light from entering. To prevent foreign objects from entering the casing 7, a frame 25 is fixedly connected to the front of the casing 7. The frame 25 is used to fix and support the screen 26. The screen 26 is fixedly connected to the inner wall of the frame 25. The screen 26 is used to display relevant parameters and operating status information of the film applicator, so that the operator can understand the equipment status. A controller 27 is fixedly connected to the bottom of the frame 25. The controller 27 is the control core of the film applicator and coordinates the work of various components. The controller 27 is connected to the transmission half gear 205, the optical path sensor 208, the lifting component 5, and the roller. The pressure head 6, film cutter 8, servo motor 21, two hydraulic rods 15, and screen 26 are electrically connected. The controller 27 receives the signal from the optical sensor 208 and controls the operation of the transmission half gear 205, lifting component 5, pressure head 6, film cutter 8, servo motor 21, and hydraulic rods 15. Simultaneously, it transmits display information to the screen 26. Positioning grooves 28 are provided around the outer wall of the film feeding roll 9. These grooves 28 cooperate with the positioning block 29 to accurately position the film feeding roll 20 on the film feeding roll 9. The inner... Positioning blocks 29 are fixedly connected to all four sides of the wall. The positioning blocks 29 cooperate with the positioning grooves 28 to prevent the film feeding roll 20 from rotating and shifting arbitrarily on the film feeding shaft 9. Multiple positioning blocks 29 are slidably connected to the inner walls of the corresponding positioning grooves 28. Fastening pads 30 are fixedly connected to one side of multiple top plates 19. The fastening pads 30 increase the friction between the top plate 19 and the inner wall of the film feeding roll 20. The other side of multiple fastening pads 30 are attached to the inner wall of the film feeding roll 20 to further stabilize the position of the film feeding roll 20 on the top plate 19.

[0039] Specifically, the inspection door 21 is used to open the inside of the chassis 7, facilitating the inspection and maintenance of the components inside the chassis 7. The handle 22 is convenient for operators to grip and open and close the inspection door 21. The observation slot 23 provides operators with a window to observe the internal operation of the chassis 7. The transparent plate 24 ensures observation while preventing foreign objects from entering the chassis 7. The frame 25 is used to fix and support the screen 26, which is used to display relevant parameters and operating status information of the laminating machine, making it convenient for operators to understand the equipment status. The controller 27 is the control core of the laminating machine, coordinating the work of various components. The positioning slot 28 is used to cooperate with the positioning block 29 to accurately position the film feeding drum 20 on the film feeding shaft 9, preventing the film feeding drum 20 from rotating or shifting arbitrarily on the film feeding shaft 9. The fastening pad 30 increases the friction between the top plate 19 and the inner wall of the film feeding drum 20.

[0040] Working Principle: When using the film applicator, the servo motor 11 is first turned on. The output of the servo motor 11 drives the drive gear 12 to rotate. Since the drive gear 12 and the transmission gear 10 are connected by the track 13, the transmission gear 10 rotates accordingly, which in turn drives the film feeding roller 9 to rotate. The hydraulic rod 15 plays a key role in the groove 14 on the inner wall of the film feeding roller 9. When the film feeding roller 20 needs to be replaced, the hydraulic rod 15 shortens, pulling the sliders 16 on both sides to slide in the groove 14, causing multiple U-shaped blocks 17 connected to the moving rod 18 to move inward. The top plate 19 at the top of the moving rod 18 then retracts, and the film feeding roller 20 can be easily removed. When installing a new film feeding roller 20, the hydraulic rod 15 extends, and the top plate 19 retracts. The plate 19 spreads outward to firmly fix the film feeding roll 20. This design greatly simplifies the film changing process and saves time. The film material on the film feeding roll 20 is fed out by the rotation of the film feeding shaft 9. After passing above the film cutting machine 8, when the film material reaches above the sliding film application platform 3, the lifting component 5 is activated. The lifting component 5 drives the roller head 6 to descend. The roller head 6 rotates and rolls on the film material, tightly adhering the film material to the surface of the item placed on the sliding film application platform 3. When the film application is completed to a certain length, the film cutting machine 8 is activated to cut the film material, completing one film application process. In the whole process, through the ingenious structural design, not only is the semi-automatic film application function realized, but more importantly, the problem of complex film changing is solved, improving equipment production efficiency and reducing production costs.

[0041] Furthermore, when the membrane material deviates and automatic correction is required, the membrane material first passes through the guide roller 204 during transport. The guide roller 204 is mounted on the horizontal shaft 203, which is connected to the rotating shaft 201 via the connecting frame 202. The bottom of the rotating shaft 201 is fixed to the top of the base 1, allowing the guide roller 204 to rotate flexibly, providing support and guidance for the membrane material transport. The output end of the servo motor 206 is connected to the drive gear 207, which meshes with the transmission half gear 205 on the rear side of the connecting frame 202. When the servo motor 206 starts, the drive gear 207 rotates. Due to the meshing relationship between the drive gear 207 and the transmission half gear 205, the transmission half gear 205 drives the connecting frame 202 to rotate around the rotating shaft 201. The rotation of the connecting frame 202 changes the angle of the guide roller 204. When the membrane material deviates to the left... The optical path sensor 208 on the top right side of the chassis 7 senses and transmits a signal to the control system, activating the servo motor 206 on the rear side of the base 1. This motor drives the drive gear 207, causing the transmission half gear 205 to rotate. The connecting frame 202 rotates counterclockwise around the rotating shaft 201, and the guide roller 204 tilts to the right, applying a force to the right to correct the film material's deviation. When the film material deviates to the right, the optical path sensor 208 transmits a signal, the servo motor 206 reverses, the drive gear 207 drives the transmission half gear 205 to rotate in the opposite direction, the connecting frame 202 rotates clockwise, and the guide roller 204 tilts to the left, applying a force to the left to correct the deviation. The automatic correction mechanism 2 can promptly detect and effectively solve the problem of film material deviation during the conveying process, ensuring that the film material always maintains an accurate position during the film application process, improving the quality and stability of the film application, avoiding poor film application caused by film material deviation, and improving the overall efficiency and reliability of the film application machine.
