Description

Technical Field

[0001] This utility model relates to the field of plastic film processing technology, and in particular to a slitting device for a plastic film coating machine. Background Technology

[0002] The slitting device uses a set of cutting blades and tension control to slit continuous rolls of material. Plastic laminating machines primarily use heating and pressure to bond plastic film to a substrate, creating laminated products with protective, decorative, or functional properties. The slitting device, typically a downstream processing unit of the plastic laminating machine, receives the wide-width laminated rolls and slits them into narrower rolls of specific widths according to actual needs, facilitating subsequent cutting, bag making, or further processing.

[0003] In existing technologies, the slitting device of a plastic laminating machine typically uses a circular or straight blade cutting method, with a motor driving the blades to continuously slit the laminating material in motion. During the slitting process, a tension control system maintains stable material feeding, guide rollers ensure that the material does not deviate, and the winding device is responsible for winding the slit product into rolls.

[0004] In the prior art, some plastic laminating machines have slitting devices that suddenly release internal stress at the cut edge of the laminating material the moment it is cut, causing the cut edge to warp or wrinkle due to elastic contraction. This requires the operator to stop the machine to clean the material, adding extra work steps and reducing overall production efficiency. To address the above problems, a slitting device for plastic laminating machines is proposed. Utility Model Content

At the same time, the transmission link 1, in conjunction with the rotating plate 1, swings around the axis limiting column 2, so that the flexible strip clamps the coating material, ensuring that the material is stable and does not deviate during cutting. After slitting, the clamping mechanism pushes the material accordingly, effectively counteracting the rebound tendency of the material caused by the release of tension, avoiding the formation of edge curling or wrinkles. The mechanism that pushes forward immediately after cutting counteracts the elastic shrinkage of the material, significantly reducing the risk of wrinkles.

In this utility model, the transmission gear is driven by the motor to rotate, and the sliding frame slides smoothly along the limiting plate by cooperating with the protruding column and the slide groove, which drives the cutter to move and cut precisely, ensuring the stability of the slitting. The cleaning column slides in contact with the cutter during cutting, which can clean up residual materials in time, avoids affecting the subsequent cutting effect, improves the slitting quality, reduces downtime maintenance caused by untimely cleaning of the cutter, and effectively improves the continuous working efficiency of the equipment.

A motor 2 is fixedly connected to the outside of the support frame 1. The motor 2 drives a transmission column to rotate, thereby driving a conveyor belt 3 to transport coating material. A transmission column is fixedly connected to the drive end of the motor 2, transmitting power from the motor 2 to drive the conveyor belt 3 synchronously. The conveyor belt 3 is sleeved on the outside of the transmission column, carrying and transporting the coating material, allowing the material to move along a predetermined path to each processing station. A blocking column 4 is rotatably connected inside the support frame 1, limiting and guiding the coating material during transport to prevent material deviation and ensure the accuracy of the transport direction. The external fixed connection of the support frame 1 includes a second motor 5, which provides power for the rotation of the tension roller 6 and adjusts the material tension. The drive end of the second motor 5 is fixedly connected to the tension roller 6, which applies appropriate tension to the film material by rotating to prevent the material from loosening or wrinkling and to ensure the slitting quality. The external sliding connection of the support frame 1 includes a film roll placement cylinder 8, which is used to limit the position of the film roll and prevent the film roll from shifting laterally or shaking during unwinding. The external of the support frame 1 includes a cutting mechanism 7, which is responsible for accurately cutting the film material into the required size. The internal of the support frame 1 includes a fixed pushing mechanism 9, which clamps and fixes the film material and pushes the material to move, thus completing the slitting and subsequent processes.

[0034] The fixed pushing mechanism 9 includes a cylinder 91, which provides power for the movement of the braking assembly 92, driving the braking assembly 92 and related components to achieve the pushing action. The cylinder 91 is externally fixedly connected to the inside of the support frame 1. The driving end of the cylinder 91 is fixedly connected to the braking assembly 92, which transmits the power of the cylinder 91, driving the transmission link 93 and subsequent components to move, thereby achieving the fixing and pushing of the material. The braking assembly 92 is externally fixedly connected to the transmission link 93, which transmits power and converts the movement of the pushing column 925 into... To enable the rotation of the rotating plate and the clamping action of the flexible strip 96, a fixed block 98 is fixedly connected to the external of the transmission connecting rod 93. The fixed block 98 provides a mounting fulcrum for the limiting post 94 and the rotating plate, ensuring the relative position of each component. The limiting post 94 is fixedly connected to the external of the fixed block 98, which restricts the movement trajectory of the rotating plate and ensures smooth rotation. A rotating plate 97 is rotatably connected to the external of the limiting post 94. A flexible strip 96 is fixedly connected to the external of the rotating plate 97.

The drive end of the telescopic column 922 is fixedly connected to the support frame 2 923, which provides installation support for cylinder 2 924 and push column 925, driving these components to move with the sliding block 921.

[0037] A cylinder 2 924 is fixedly connected to the outside of the support frame 2 923. A push column 925 is fixedly connected to the drive end of the cylinder 2 924. The cylinder 2 924 provides power for the sliding of the push column 925, driving the push column 925 to achieve telescopic movement. The push column 925 slides under the drive of the cylinder 2 924, and drives the rotating plate to rotate through the transmission connecting rod 1 93, thereby realizing the clamping action of the flexible strip 96. The outside of the push column 925 is slidably connected to the inside of the fixed block 98. The other end of the transmission connecting rod 1 93 is rotatably connected to the outside of the push column 925. The top of the push column 925 is rotatably connected to the outside of the transmission connecting rod 1 926. The outside of the transmission connecting rod 1 926 is rotatably connected to the middle of the rotating plate 1 95.

[0038] Reference Figure 1 , Figure 4 and Figure 5 The cutting mechanism 7 includes a limiting plate 72, which provides installation and movement guidance for the sliding frame 71 and the transmission gear 75, and limits their range of motion. The limiting plate 72 is externally fixedly connected to the outside of the support frame 1. The sliding frame 71 is slidably connected to the outside of the limiting plate 72. The motor 76 is externally fixedly connected to the outside of the sliding frame 71. The drive end of the motor 76 is fixedly connected to the transmission gear 75. The transmission gear 75 rotates under the drive of the motor 76 and cooperates with the protruding column 73 and the slide groove 74 to drive the sliding frame 71 to slide.

[0039] The limiting plate 72 is externally fixedly connected to multiple protruding posts 73. These protruding posts 73 cooperate with the transmission gear 75, guiding and limiting the movement of the transmission gear 75, ensuring smooth movement of the sliding frame 71 driven by the transmission gear 75. The transmission gear 75 is externally slidably connected to the outside of the protruding posts 73. The limiting plate 72 has an externally formed groove 74, which provides a sliding track for the transmission gear 75, further ensuring the stability and accuracy of its movement. The groove 74 is externally slidably connected to the outside of the transmission gear 75. The sliding frame 71 is externally fixedly connected to... There is a cutter 77, which moves under the drive of the sliding frame 71 to cut the film material. The support frame 1 is fixedly connected to the outside of the fixed plate 79, which provides installation support for the cleaning column 78 and fixes the position of the cleaning column 78. The fixed plate 79 is fixedly connected to the outside of the limiting plate 72. The cleaning column 78 is rotatably connected to the inside of the fixed plate 79. The cleaning column 78 contacts the cutter 77 during the sliding process of the cutter 77 to clean the residual material on the cutter 77 and ensure the cutting effect. The external side of the cutter 77 is slidably connected to the cleaning column 78.

[0040] Working principle: The transmission column is driven to rotate by motor 2, which drives the conveyor belt 3 to transport the film material to the working area of ​​the slitting device. The blocking column 4, which is rotatably connected inside the support frame 1, can guide and limit the material conveying path. Motor 2 drives the tension roller 6 to rotate, applying constant tension to the film material to prevent it from loosening or wrinkling during the conveying process, thus ensuring the smooth progress of subsequent slitting work. The film roll placement cylinder 8, which is slidably connected to the outside of the support frame 1, can prevent the film roll from shaking during the conveying process.

[0041] The cylinder 924 drives the push column 925 to slide within the fixed block 98, which in turn drives the transmission link 93 to rotate. This, in turn, drives the rotating plate 97 to move up and down around the axis limiting post 94. Simultaneously, the transmission link 926 drives the rotating plate 95 to move around the axis limiting post 99, causing the flexible strip 96 to clamp the coating material. This clamps and fixes the coating material. Then, in conjunction with the cylinder 91, the sliding block 921 is driven to slide along the inside of the support frame 1. The telescopic column 922, which is fixedly connected to the outside of the sliding block 921, also moves accordingly. The driving end of the telescopic column 922 is fixedly connected to the support frame 923, which drives the support frame 923 to move forward. This facilitates clamping and pushing the material forward after cutting, preventing wrinkles caused by springback after slitting.

[0042] The transmission gear 75, which is fixedly connected to the drive end of the motor 76, rotates. The external part of the transmission gear 75 is slidably connected to the protruding post 73 outside the limit plate 72 and slides in the slide groove 74. The transmission gear 75 drives the sliding frame 71 to move laterally along the limit plate 72. When it reaches the end of the slide groove 74, the cutter 77 presses down along the trajectory of the slide groove 74 to complete the cutting. During the cutting process, the cutter 77 cuts the film when it moves downward and slides up and down between the two cleaning posts 78 fixed on the fixed plate 79 to clean the cutter 77 and prevent residual material on the cutter 77 from affecting the cutting effect.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
