Description

Technical Field

[0001] This utility model belongs to the field of packaging machinery technology, specifically relating to a non-stop film application machine. Background Technology

[0002] In the field of packaging machinery technology, laminating machines are key equipment for achieving surface lamination of products, improving packaging quality and protective performance, and are widely used in product packaging processes in industries such as food, daily chemicals, and electronics. However, most conventional laminating machines on the market currently adopt a "single feeding tray + single conveyor path" structural design, which has certain limitations in actual production processes.

[0003] When the film paper on the feeding tray is completely used up, the entire film application production line must be stopped. Operators need to manually disassemble the empty feeding tray, install a new film paper roll, and recalibrate the film paper conveying path. This film replacement process usually takes 3-10 minutes (the specific time depends on the film paper roll specifications and the operator's proficiency), causing production interruption. A lot of time is wasted waiting for film replacement, which seriously restricts the overall production efficiency. Especially for scenarios of large-volume continuous production, the capacity loss caused by downtime for film replacement is even more significant. Utility Model Content

[0004] The purpose of this invention is to provide a non-stop film application machine to solve the problem mentioned in the background art, which is that when the film paper on the feeding tray is completely used up, the entire film application production line must be stopped, resulting in production interruption and a lot of time wasted waiting for film replacement, which seriously restricts the overall production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a non-stop film application machine, comprising a chassis, a base, a first frame, and a second frame. The base is fixed inside the chassis. The first and second frames are both mounted on the surface of the base. Multiple guide rollers are mounted on both the first and second frames, and clamping mechanisms are also mounted on both frames. Multiple upper roller shafts are mounted on the second frame. Two fixed columns are fixed inside the second frame. Sliding seats are slidably connected to the outside of the fixed columns. Multiple lower roller shafts are mounted on the sliding seats. A fixing mechanism is mounted on the second frame.

[0006] In a further embodiment, the clamping mechanism consists of a positioning roller, a limiting member, and a clamping roller. A driving cylinder is provided below the clamping roller, and a mounting base is fixed to the output end of the driving cylinder. One end of the clamping roller is mounted on the mounting base.

[0007] In a further embodiment, a drive motor is mounted on the back of the second frame, and the output shaft of the drive motor is fixedly connected to one end of the positioning roller on the second frame.

[0008] In a further embodiment, the fixing mechanism consists of two fixed seats and two dual-axis cylinders. The fixed seats are mounted on the second frame, and the dual-axis cylinders are mounted inside the fixed seats. Both drive ends of the dual-axis cylinders are equipped with pressure plates that are movably connected to the fixed seats.

[0009] In a further embodiment, a feeding tray is provided on the first frame, a rotary motor is installed on the back of the second frame, and a receiving tray is provided on the second frame, with the output shaft of the rotary motor fixedly connected to the receiving tray.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] This non-stop film applicator uses a temporary storage structure of "upper roller shaft + lower roller shaft + sliding seat". During the film changing process, the film paper temporarily stored between the upper roller shaft and the lower roller shaft can be continuously released. With the help of the fixing mechanism to stably connect the new and old film paper, there is no need to stop the operation of the equipment. Compared with traditional film applicators, it can effectively reduce downtime and is especially suitable for large-volume continuous production scenarios, significantly improving the overall production line capacity.

[0012] In the clamping mechanism, the drive cylinder can flexibly adjust the clamping gap between the clamping roller and the positioning roller according to the thickness of the film paper, adapting to film paper of different thicknesses, avoiding slippage or damage to the film paper during conveying. This non-stop film application machine can replace the film paper without stopping the machine, saving the waiting time for replacing the film paper, thereby improving production efficiency.

[0022] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0023] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0024] This utility model provides, for example Figure 1-7The illustrated non-stop film applicator includes a casing 1, a base 2, a first frame 3, and a second frame 4. The first frame 3 and the second frame 4 are both mounted on the surface of the base 2. A punching mechanism (not shown) is installed at a suitable position inside the casing 1 for punching and forming the film paper to fit the shape of the product to be applicated. A feeding tray 5 is provided on the first frame 3. Multiple guide rollers 6 are installed on both the first frame 3 and the second frame 4. A rotary motor 17 is installed on the back of the second frame 4, and a receiving tray 18 is provided on the second frame 4. The output shaft of the rotary motor 17 is fixedly connected to the receiving tray 18. A clamping mechanism is installed on both the first frame 3 and the second frame 4. The clamping mechanism consists of a positioning roller 7, a limiting member 8, and a clamping roller 11. A drive cylinder 9 is provided below the clamping roller 11. A mounting base 10 is fixed to the output end of the drive cylinder 9, and one end of the clamping roller 11 is mounted on the mounting base. On the 10, the other end of the clamping roller 11 is movably connected to the limiting member 8. The back of the frame 2 4 is equipped with a drive motor 12, and the output shaft of the drive motor 12 is fixedly connected to one end of the positioning roller 7 on the frame 2 4. An adjustable clamping gap is reserved between the positioning roller 7 and the clamping roller 11. The size of this gap can be adjusted by driving the mounting base 10 to rise and fall through the drive cylinder 9 to adapt to film paper of different thicknesses and meet different processing requirements. When the drive motor 12 works, it can drive the positioning roller 7 on the frame 2 4 to rotate, which can stably drag the film paper, thereby helping to provide stability for film paper conveying. The drive motor 12 is preferably a servo motor, which can accurately control the speed through the PLC control system to ensure that the speed of the positioning roller 7 driving the film paper conveying matches the processing speed of the subsequent punching mechanism and the winding speed of the take-up mechanism, so as to avoid stretching or wrinkling of the film paper.

[0025] Multiple upper rollers 13 are installed on the frame 2 4. Two fixed columns 14 are fixed inside the frame 2 4. Sliding seats 15 are slidably connected to the outside of the fixed columns 14. Multiple lower rollers 16 are installed on the sliding seats 15. The surfaces of the upper rollers 13 and lower rollers 16 are covered with a rubber layer to increase the friction with the film paper and avoid scratching the surface of the film paper. A linear bearing is added at the joint between the sliding seat 15 and the fixed column 14 to reduce the frictional resistance when the sliding seat 15 slides up and down, ensuring that the sliding seat 15 can descend smoothly and steadily under the action of gravity, realizing the stable release and storage of the film paper. The film paper is alternately passed between the multiple upper rollers 13 and lower rollers 16 to temporarily store the film paper. When the film paper on the feeding tray 5 is exhausted, the film paper on the multiple upper rollers 13 and lower rollers 16 is released. This saves the waiting time for replacing the film paper on the feeding tray 5, so that the film paper can be replaced without stopping the machine, thereby improving production efficiency.

[0026] A fixing mechanism is installed on frame 24. The fixing mechanism consists of two fixing seats 19 and two dual-axis cylinders 20. The fixing seats 19 are installed on frame 24, and the dual-axis cylinders 20 are installed inside the fixing seats 19. Both drive ends of the dual-axis cylinders 20 are equipped with pressure plates 21 that are movably connected to the fixing seats 19. A support plate is also added to the fixing seats 19. The surface of the support plate needs to be smoothed (roughness Ra≤0.8μm) to support the beginning and end of the film paper to be joined, so as to facilitate the operator to perform the film paper joining operation and avoid scratching the film paper during the joining process. When the film paper on one feeding tray 5 is almost empty, the end of the film paper is placed on the fixing seat 19 and clamped by the pressure plate 21 on the right. Then, the end of the film paper on the other feeding tray 5 is wound around the guide roller 6, passes through the fixing mechanism, and is placed on the fixing seat 19. Then, the left... The side pressure plate 21 clamps the newly inserted film paper, and then the film paper is joined on the fixed seat 19. This allows for convenient and stable joining of two film papers together. When the right pressure plate 21 clamps the end of the film paper, the drive motor 12 drives the positioning roller 7 to rotate, which will still drag the film paper. At this time, the film paper will drag the sliding seat 15 and each lower roller shaft 16 to move upward, thus still being able to stably transport the film paper. When the film paper is joined, the two pressure plates 21 are released. The sliding seat 15 and each lower roller shaft 16 will move downward under their own gravity, and at this time, they can drag the film paper to complete the feeding tray 5 to feed the material. At this time, a certain length of film paper will be stored between the upper roller shaft 13 and the lower roller shaft 16. When the sliding seat 15 slides to the lowest position, it stops. The drive motor 12 drives the positioning roller 7 to rotate, continuing to transport new film paper, thus meeting normal usage requirements.

[0029] Working principle:

[0030] When the machine starts running without stopping, the feeding tray 5 containing the film paper is installed on the frame 3. The film paper passes through the gap between the positioning roller 7 and the clamping roller 11 in the clamping mechanism, and then alternately passes through the upper roller shaft 13 on the frame 4 and the lower roller shaft 16 on the sliding seat 15. Finally, it is connected to the receiving tray 18 on the frame 4. After the machine is started, the rotary motor 17 drives the receiving tray 18 to rotate, and at the same time, the drive motor 12 drives the positioning roller 7 on the frame 4 to rotate. The two work together to drag the film paper along the preset path at a stable speed.

[0031] During the process, the drive cylinder 9 of the clamping mechanism adjusts the height of the mounting base 10 according to the film thickness, thereby adjusting the clamping gap between the clamping roller 11 and the positioning roller 7 to ensure that the film does not slip or break during conveying. At the same time, the punching mechanism in the machine box 1 simultaneously punches and shapes the conveying film to adapt to the shape of the product to be laminated. When the film on the current feeding tray 5 is about to run out, a film replacement operation is performed without stopping the machine: first, place the end of the film that is about to run out on the support plate of the fixed base 19 of the fixing mechanism, and control the right-side dual-axis cylinder 20 to drive the pressure plate 21 to clamp the end of the film. Then, install the pre-prepared new film roll into the spare position of the frame 3 (or directly replace the feeding tray 5), and place the end of the new film around the guide roller 6, through the fixing mechanism, and then on the fixed base. On the support plate 19, the left-side dual-axis cylinder 20 drives the pressure plate 21 to clamp the new film paper. The operator completes the docking of the new and old film papers on the fixed seat 19 (such as using special tape for bonding or heat sealing). During docking, the positioning roller 7 and the receiving tray 18 continuously drag the film paper. The film paper will drive the sliding seat 15 to slide upward along the fixed column 14. The film paper temporarily stored between the upper roller shaft 13 and the lower roller shaft 16 is gradually released to ensure that the film paper is conveyed without interruption. After docking is completed, the dual-axis cylinder 20 is controlled to release the pressure plates 21 on both sides. The sliding seat 15 slides downward along the fixed column 14 under its own gravity, restoring the temporary storage state of the film paper between the upper roller shaft 13 and the lower roller shaft 16. The new feeding tray 5 starts to feed material normally, and the equipment continues to perform film application operations, realizing full-process non-stop operation.
