Description

A release film production detection system

Technical Field

The invention relates to the technical field of release film detection, and in particular to a release film production detection system.

Background Art

As we all know, release film is made by coating silicone release agent on the surface of environmentally friendly PET, PE, and OPP films, allowing it to exhibit extremely light and stable release force against various organic pressure-sensitive adhesives; the quality control indicators in the release film production process are mainly tensile strength and viscosity of the release surface.

For example, a Chinese invention patent discloses a release film tension detection device and a detection method thereof (publication number CN116067776A), including a bidirectional screw rod, which is arranged at the front and rear ends inside the main bracket, and the main bracket is rotatably connected to the bidirectional screw rod through a bearing, and a movable mounting block is installed on the outside of the bidirectional screw rod. The device can squeeze the pressure sensor by installing a pressure detection block, which is convenient for detecting the tension borne by the release film and ensuring the functional integrity of the device. The installation of a winding and clamping roller can not only adjust the length of the release film, but also the release film is wound on the outside of the winding and clamping roller, so that when the release film is tested for tension, the contact part between the release film and the winding and clamping roller is subjected to more uniform force, thereby preventing the edge of the release film from being damaged and affecting the detection accuracy. The installation of a clamping plate can clamp the two ends of the release film, ensuring that the winding and clamping roller can wind up the release film, temporarily limit the two ends of the release film, play a temporary clamping role, and enhance the use effect of the device.

However, when the inventors implemented this device, they found the following defects: it can only detect the tensile strength of the release film, and the detection function is single; and the amount of release film material used for detection is large, resulting in waste of release film; the release film material used for detection is often taken from the starting head and the end of the release film roll in a rolled state, and the machine needs to be stopped for sampling of the release film. The sampling convenience of the release film material for detection is poor, which affects the quality inspection efficiency of the release film during the production process.

The release film samples are taken from the head and tail of each set of winding rollers, which improves the convenience of sampling the release film samples. The tensile strength and viscosity test of the release film can be completed in a single time, improving the efficiency of release film inspection.

When the winding roller 5 winds the release film into shape, the corresponding braking servo motor stops working; the second rotary driver 7 includes a driving shaft rotatably mounted on the seat frame 3, an electric motor fixedly mounted on the seat frame 3, and a transmission belt for driving the driving shaft and the output end of the motor; the second rotary driver 7 can also use other rotary drivers with the effect of driving the rotating frame 4 to rotate; the first heating wire 8 is arranged parallel to the two winding rollers 5, and the central axes of the first heating wire 8 and the two winding rollers 5 are located in the same horizontal plane; the mold frame 11 adopts a rectangular hollow mold frame, and the mold frame 11 is located below the middle of the two first heating wires 8; the clamping limit mechanism is used to limit the release film that falls on the mold frame 11; during the rotation of the rotating frame 4, the release film is always located at the bottom of the winding roller 5.

Please refer to Figure 5, the viscosity detection mechanism 43 includes a mounting base 12 fixedly mounted on the base frame 3, a first tension sensor 13 mounted on the top of the mounting base 12, a frame body 14 mounted on the first tension sensor 13, a reel 15 rotatably mounted on the frame body 14, a guide feed frame 16 hingedly mounted on the frame body 14, a guide wheel 17 rotatably mounted on the guide feed frame 16, and a third rotary driver 18 for providing power for the rotation of the guide feed frame 16; further, the third rotary driver 18 is preferably a telescopic cylinder, which is hingedly mounted on the frame body 14, and the output end of the telescopic cylinder is hinged to the guide feed frame 16; the third rotary driver 18 can also adopt other rotary drivers such as a braking stepping motor that can drive the guide feed frame 16 to rotate.

Example 2

The release film production detection system provided in Example 1 is further optimized. Specifically, as shown in Figure 4, the tension detection mechanism 44 includes two clamping tensioners symmetrically arranged on the lifting seat 10, and the clamping tensioner includes a mechanical slide 19 installed on the lifting seat 10, a second tension sensor 20 installed on the mechanical slide 19, and a first thumb clamp 21 installed on the second tension sensor 20; the first thumb clamp 21 is provided with two first clamping parts 22 arranged parallel to each other, and openings 23 are provided on both sides of the top of the mold frame 11 to allow the first clamping part 22 to pass through.

Example 3

The release film production detection system provided in Example 2 is further optimized. Specifically, as shown in Figures 3-4, the clamping and limiting mechanism includes a lifting cylinder 24, a lifting platform seat installed at the output end of the lifting cylinder 24, a second thumb clamp 26 installed on the lifting platform 25, and a clamping rod 27 arranged at the clamping end of the second thumb clamp 26; further, the outer wall of the clamping rod 27 is coated with a plastic rubber layer, and the clamping rod 27 is flexibly in contact with the release film through the plastic rubber layer.

In the release film production and detection system provided in this embodiment, when the sampled release film falls to the mold frame 11, the two ends of the release film naturally hang down at the vertical walls on both sides of the mold frame 11, and the lifting cylinder 24 drives the lifting platform 25 and the second thumb clamp 26 on the lifting platform 25 to move up until the clamping rod 27 is located in the middle and lower part of the mold frame 11, and then the second thumb clamp 26 is actuated, and the clamping rod 27 approaches the mold frame 11. At this time, the distance between the clamping rod 27 and the outer wall of the mold frame 11 is slightly larger than the release film The lifting cylinder 24 then drives the lifting seat 10 to move downward, and the clamping rod 27 moves downward along the vertical outer wall of the mold frame 11, so that the release film is closely attached to the outer wall of the mold frame 11. When the clamping rod 27 moves to the bottom of the vertical outer wall of the mold frame 11, the second thumb clamp 26 is further actuated, and the clamping rod 27 presses the release film tightly against the mold frame 11. The flattening and clamping limit of the release film are achieved through the clamping limit mechanism, which provides a guarantee for the smooth bonding of the subsequent standard tape and the release film.

Specifically, please refer to Figure 5 or Figure 6, which also includes a clamping mechanism, which includes a first feed cylinder 28 fixedly mounted on the frame 14 and a pressing wheel 29 rotatably mounted on the first feed cylinder 28; further, the pressing wheel 29 is located below the guide wheel 17; when the standard tape is attached to the release film, the output end of the feed cylinder is extended, and the pressing wheel 29 presses the standard tape tightly against the release film, ensuring that the standard tape fits tightly against the release film, thereby providing a guarantee for the accuracy of subsequent adhesion detection of the release film.

Specifically, please refer to Figures 5-6. A clamping and shearing mechanism is installed on the frame 14, and the clamping and shearing mechanism includes a second feeding cylinder 30 fixedly installed on the frame 14, a mounting plate 31 installed on the output end of the second feeding cylinder 30, a pair of scissors 32 installed on the mounting plate 31, and a third feeding cylinder 33 for providing power for the opening and closing of the scissors 32. One set of blades on the scissors 32 is provided with a clamping plate 34 that fits with the other blade, and the scissors 32 are located between the guide wheel 17 and the pressing wheel 29; further, the third feeding cylinder 33 is fixedly installed on the mounting plate 31, a set of handles of the scissors 32 is fixedly installed on the mounting plate 31, and the other set of handles of the scissors 32 can move freely, and the output end of the third feeding cylinder 33 can drive the movable handle to reciprocate around the hinge of the two handles; when the standard tape is attached to the outer wall of the release film, the second feeding cylinder 30 The scissors 32 are driven to approach the standard tape until the standard tape is completely located at the blade of the scissors 32, and the third feed cylinder 33 is actuated, the scissors 32 are closed, and the standard tape is cut by the scissors 32. At this time, one end of the standard tape pasted on the release film enters between the clamping plate 34 and the corresponding blade of the scissors 32 and is clamped; during the adhesion test of the release film, the end of the standard tape bonded to the release film is clamped between the clamping plate 34 and the blade of the scissors 32, so as to achieve the clamping limit of the end of the standard tape, so as to avoid the standard tape being continuously pulled out during the adhesion test of the release film, thereby reducing the waste of the standard tape and ensuring the accuracy of the adhesion test of the release film; when the standard tape is torn off from the release film, the scissors 32 are opened, the used standard tape is unloaded, and the new standard tape is passed around the pressing wheel 29 again.

Specifically, please refer to Figure 4; a first rotating shaft 35 is rotatably mounted on the mechanical slide 19, and the second tension sensor 20 is fixedly mounted on the first rotating shaft 35.

The synchronous driver includes a second rotating shaft 36 rotatably mounted on the lifting seat 10, a sleeve 37 fixedly mounted on the mechanical slide 19, a driving wheel 38 and a synchronous belt 39 rotatably mounted on the sleeve 37, and the driving wheel 38 is slidably mounted on the second rotating shaft 36, and the driving wheel 38 is connected to the first rotating shaft 35 through the synchronous belt 39. A fourth rotating driver 40 for driving the second rotating shaft 36 to rotate is installed on the lifting seat 10; the clamping end of the first thumb clamp 21 is provided with two second clamping parts 41 arranged parallel to each other; further, the fourth rotating driver 40 is preferably an electric motor and The transmission belt and the motor are fixedly installed on the lifting seat 10, and the output end of the motor is connected to the second rotating shaft 36 through the transmission belt; the second rotating shaft 36 is provided with a slide groove arranged along the axial direction of the second rotating shaft 36, and the driving wheel 38 is provided with a slide rail that can slide along the slide groove; when the tensile strength and viscosity of the release film are tested, the second clamping part 41 on the first thumb clamp 21 clamps the vertical walls at both ends of the mold frame 11, and the clamping limit mechanism disengages from the clamping limit of the release film. At this time, the fourth rotary driver 40 drives the second rotating shaft 36 to rotate. After the drive wheel 38 and the synchronous belt 39 are driven, the first rotating shaft 35 drives the second tension sensor 20 and the first thumb clamp 21 to rotate, and the mold frame 11 rotates. The top surface of the mold frame 11 gradually tilts, causing the release film on the mold frame 11 that has been tested to slide down and discharge by itself under the action of gravity without human intervention.

Specifically, there are multiple groups of viscosity detection mechanisms 43, and the multiple groups of viscosity detection mechanisms 43 are evenly distributed on the base frame 3. The viscosity of the release film can be tested by multiple groups of data at a time through the multiple groups of viscosity detection mechanisms 43, and the average value of the multiple groups of data is taken as the detection value of the viscosity of the release film, so as to improve the accuracy of the release film viscosity detection data.

Specifically, two second heating wires 42 are provided on the top of the mold frame 11; further, the spacing between the second heating wires 42 can be adaptively adjusted according to the tensile strength detection width standard of the release film. When the tensile strength of the release film needs to be tested, the two second heating wires 42 are started. At this time, the release film located between the two second heating wires 42 is the release film of the standard width required for the test.

Specifically, a pressing frame 45 is hingedly installed on the lifting seat 10, and a pressure roller 46 is rotatably installed on the pressing frame 45. The pressure roller 46 is arranged corresponding to a group of winding rollers 5 adjacent to the frame 1. A propulsion cylinder 47 is hingedly installed on the lifting seat 10, and the output end of the propulsion cylinder 47 is hinged to the pressing frame 45; when the first heating wire 8 cuts off the release film, the output end of the propulsion cylinder 47 extends, and the pressing frame 45 drives the pressure roller 46 to approach the corresponding winding roller 5 and presses the release film on the corresponding winding roller 5, ensuring that the winding roller 5 can smoothly and continuously wind the release film, avoiding the release film from being separated from the corresponding winding roller 5, so as to ensure the smooth progress of the release film production operation.

The use process of the release film production detection system provided by the present invention is as follows: the release film passes around the guide roller 2 and is wound around a group of winding rollers 5 close to the frame 1. The first rotary driver 6 drives the corresponding winding roller 5 to rotate to wind the release film. When the release film is rolled and formed, the winding roller 5 stops moving, and the second rotary driver 7 drives the rotating frame 4 to rotate 180 degrees and then stops (when FIG. 3 is used as a reference figure, the rotating frame 4 rotates clockwise), the positions of the two winding rollers 5 are interchanged, and the lifting driver 9 drives the lifting The seat 10 moves upward, and the mold frame 11 contacts the release film and continues to move upward until the release film contacts the two first heating wires 8 on the rotating frame 4. Under the heating effect of the first heating wires 8, the release film between the two first heating wires 8 is cut off, and the cut release film falls onto the mold frame 11. At this time, a group of winding rollers 5 adjacent to the frame 1 continue to wind up the release film coming from one side of the frame 1, and unload the formed release film roll. The cut release film is flattened by the clamping and limiting mechanism and then tightly pressed onto the mold frame 11.

When the lifting driver 9 drives the lifting seat 10 to move downward, the viscosity detection mechanism 43 adheres the standard tape to the centrifugal membrane, and when the lifting driver 9 drives the lifting seat 10 to move upward, the viscosity detection mechanism 43 detects the viscosity between the standard tape and the release film;

After the stickiness test of the release film is completed, the two second heating wires 42 are started and the release film on the top of the mold frame 11 is cut into the required standard width, and the tensile strength of the cut release film is tested by the tension testing mechanism 44;

After the release film tensile test is completed, the release film for testing is cut and preparations are made for the next release film testing process.
