Description

Technical Field

[0001] The invention relates to the technical field of release film coating and film splicing, in particular to an automatic film splicing device for release film coating production. Background Art

[0002] Release film refers to a film with a distinguishable surface. When the release film comes into contact with a specific material under limited conditions, it is non-sticky or slightly sticky. After the existing release film is coated, it needs to be laminated with an isolation film and then rolled up by a film splicing device; The existing film splicing device generally cooperates with the cutting device and the pressing device to ensure automatic splicing and winding operations, but this method still has the following problems: 1. The existing cutting device is generally a cutter, etc., and the interface of the release film after cutting cannot be guaranteed to be neat and uniform, causing the release film to fold near the roll when changing the roll, resulting in a large number of defects, resulting in quality problems and waste; 2. The existing lamination device generally adheres the release film to the side of the roll by hot melting or glue, so that after the release film is subsequently used, the roll will be defective due to adhesion, causing the roll to be unable to be reused. In addition, the existing rolls are generally made of paper, and the wasted rolls also cause waste of resources.

[0011] Compared with the prior art, the present invention can achieve the following beneficial effects: 1. The present invention can continuously clamp the release film to ensure the bonding effect by arranging a material guiding mechanism, a film splicing mechanism and a driving mechanism. When splicing the film, the winding operation can be performed without waiting for the release film to be cut, and the cutting is smooth. When winding, the release film can be continuously constrained and coordinated to ensure the winding effect of the release film. While winding, the waste material after cutting can be synchronously collected. In this way, after the wound release film is used, there is no adhesion operation on the side of the roll, which will not cause waste of the release film and will not affect the subsequent normal repeated use of the roll.

[0012] 2. The present invention provides a material guiding mechanism, and the pressure plate can clamp the release film. The clamped release film can be smoothly moved in coordination with the movement of the mounting plate so that it can be perfectly inserted into the connecting cavity. The synchronously wound release film is cut by a cutting device, and can also be clamped by the pressure plate to ensure that the release film can be subsequently spliced ​​and wound for use. During winding, the pressure plate also ensures the fitting effect of the first isolation film roll, the second isolation film roll and the base film.

[0013] 3. The present invention sets a film splicing mechanism, and the cutting plate is first driven to the side position of the support plate, which can clamp the release film so that the release film will not be wrinkled when it is rolled up on the side of the roll, and the rolling operation can be performed without adhesion. Then the cutting plate squeezes the support plate to ensure the stable cutting operation of the release film through the support of the support plate. The cutting plate can also perform isolation operation on the inside of the film roller to ensure the subsequent waste cleaning effect.

[0014] 4. The present invention sets a driving mechanism, the first motor can drive the connecting block to connect the film roller to perform an overall driving operation, when the cutting plate is clamped and cut, the seventh electric push rod pushes the clamping block to clamp with the matching block, the second motor drives the matching block to make the cutting plate slide inside the connecting cavity, after cutting, the second motor stops driving to keep the cutting plate stationary, the sixth electric push rod pushes the friction block to fit the adjusting shaft, and the third motor drives the adjusting shaft and the cleaning block thread to drive it to slide inside the film roller to clean the waste, so that the release film can be kept when it is rolled up, and the clamping, cutting and cleaning of the release film can be completed, thereby ensuring the efficiency of film rolling up; In addition, the sixth electric push rod pulls the movable block to the staggered matching block position, and the seventh electric push rod pushes the card block to fit the film joining roller position, so that the card block further supports the inner side of the film joining roller, ensuring the stability of the film joining roller driven by the first motor to rotate, and avoiding the shaking of the film joining roller affecting the winding operation.

[0015] 5. The present invention provides a limit block and its peripheral components. The fourth electric push rod initially pushes the limit block to the inside of the roll, which can complete the positioning and limiting operation of the roll. The fourth electric push rod continues to push the limit block to limit the side of the release film winding, thereby ensuring the effect of the release film winding; The synchronously coordinated pressing plate always maintains a fixed distance from the rolled release film, ensuring that the angle of the release film rolling will not change, thereby improving the film splicing and rolling effect.

[0020] Working principle: Before use: First, according to whether the release agent is coated on one side or both sides of the base film 23, the required first isolation film roll 21 and the second isolation film roll 22 are attached to the side position of the base film 23, and the combined release film is placed between the pressing plates 36 for clamping; In the second step, the second electric push rod 42 pushes the support frame 41 to slide out of the inner side of the main frame 2, and the film-joining roller 43 is removed by the lifting device, and the roll 44 on its side is peeled off for replacement. The second electric push rod 42 pulls the support frame 41 to return to the inner side of the main frame 2, and the roll 44 is manually rotated so that the rectangular groove on its side corresponds to the position of the connecting cavity 431. The position of the limit block 434 is moved by the third electric push rod 432 and the fourth electric push rod 433 so that it is inserted into the roll 44 to limit it. Step 3: The fifth electric push rod 52 and the sixth electric push rod 54 are used to make the connection block 53 fit to the side of the film splicing roller 43 and the position of the movable block 56 to the matching block 471, waiting for the film splicing and winding operation; When in use: In the first step, the first electric push rod 32 pushes the mounting plate 33 to insert the clamped release film into the connecting cavity 431, the seventh electric push rod 57 pushes the clamping block 58 to clamp with the matching block 471, and the second motor 55 drives the cutting plate 46 to slide inside the connecting cavity 431 to the position of the supporting plate 463, and the cutting plate 46 clamps the release film, and the first motor 51 drives the connecting block 53 to drive the film connecting roller 43 to rotate, and the release film is rolled up on the side of the reel 44, thereby ensuring the effect of rolling up the release film; In the second step, the release film is continuously rolled up on the side of the reel 44. When the film is rolled up for one circle, the second motor 55 continues to drive the cutting plate 46 to squeeze the support plate 463 to cut the release film. The cutting plate 46 pushes the support plate 463 to slide inside the limit rod 461. At this time, the cutting plate 46 isolates the inner side of the film roller 43 to ensure that the cutting surface is flat and there is no need to stop the rolling to ensure efficiency. In the third step, after the release film is cut, the second motor 55 stops driving, the sixth electric push rod 54 pushes the friction block 591 to fit the side of the adjustment shaft 436, and the third motor 59 drives the adjustment shaft 436 to engage with the cleaning block 437 to slide inside the film-joining roller 43 to push the cut release film waste to the inner position of the collection box 45, and then the third motor 59 drives in the reverse direction to reset the cleaning block 437, and completes the waste collection operation during winding, and there is no need to stop winding to ensure efficiency; In the fourth step, after the waste is collected, the sixth electric push rod 54 pulls the movable block 56 to interlace with the matching block 471, and the seventh electric push rod 57 continues to push the clamping block 58 to fit the inner side of the film-joining roller 43. The clamping block 58 further supports the film-joining roller 43, ensuring the stable driving and rotating operation of the first motor 51 to the film-joining roller 43, so that no shaking occurs when the release film is rolled up; When the reel 44 is rolling up the release film, the fourth electric push rod 433 pushes the limit block 434 to move, so that the limit block 434 is continuously kept at the side position of the release film rolling up, which plays a restraining role and ensures the effect of the release film rolling up; the first electric push rod 32 pulls the mounting plate 33 to slowly reset, so that the pressure plate 36 continues to clamp the first isolation film roll 21, the second isolation film roll 22 and the base film 23 together stably, and cooperates with the change of the large diameter of the rolling up to ensure that the pressure plate 36 always keeps a fixed distance from the rolled up release film, ensuring that the angle of the release film rolling up does not change, thereby improving the effect of the film splicing and rolling up; After use, the release film is cut by the cutting device on the side of the pressure plate 36, and the pressure plate 36 keeps clamping the release film. The fifth electric push rod 52 and the sixth electric push rod 54 pull the movable block 56 out of the internal position of the film splicing roller 43, and the second electric push rod 42 pushes the support frame 41 to slide out. The film splicing roller 43 is removed by the lifting device, and the reel 44 on its side is peeled off for replacement, and the collection box 45 can be threadedly removed to pour out the waste. The subsequent film splicing and winding operations can be carried out by performing the above steps.

[0021] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
