Description

Technical Field

[0001] The invention relates to the technical field of composite film flaw detection, in particular to an online nondestructive flaw detection instrument for composite material films. Background Art

[0002] Composite film is a thin film material made of two or more different materials combined by physical or chemical methods. These materials can include polymers, metals, ceramics, etc. The combined composite film can combine the excellent properties of each component material, such as high strength, barrier properties, corrosion resistance, etc.

[0003] After the existing composite film is made, a winding device is set at the film outlet for winding up for standby use. When winding up, a flaw detection instrument is generally set up to detect the composite film, such as an ultrasonic flaw detector, a radiographic flaw detector, an infrared thermal imager and other instruments. The existing flaw detection instrument can only detect the film and mark the unqualified sections. When it is used in the later stage of winding, the waste section needs to be manually cut off and removed, which causes inconvenience in use. If it is not cut off, stratification and bubbles may destroy the barrier properties of the composite film, making it easier for small molecules such as oxygen and moisture to pass through, affecting the shelf life of the product.

[0019] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0020] 1. The present invention provides an auxiliary mechanism, a waste mechanism, a matching mechanism, a trigger assembly, a first cutting assembly and a second cutting assembly, so that after the composite material film is produced, the film can be rolled up for online flaw detection, and the waste segment can be cut off and collected during rolling. After the waste segment is collected, the connection and rewinding operation can be performed to ensure the isolation performance of the film and avoid the generation of bubbles and stratification that affect the film performance.

[0021] 2. The present invention sets a waste mechanism and a matching mechanism. The fourth electric push rod pushes the rotating rod vertically so that the hot melt module extrudes the composite film and fits the side of the waste roller. The electric slide drives the fourth electric push rod to slide. The fourth electric push rod pushes the rotating rod vertically so that the hot melt module extrudes the composite film and fits the side of the waste roller. The electric slide drives the fourth electric push rod to slide, so that the composite film can be adhered to the side of the waste roller to perform the waste segment winding operation. In addition, in normal use, the upper side mounting plate can be away from the composite film to avoid interference, and the lower side mounting plate can make the auxiliary roller fit the side of the composite film to assist in supporting the composite film, thereby realizing the collection of the composite film waste segment.

[0022] 3. The present invention sets a matching mechanism, a trigger assembly, a first cutting assembly and a second cutting assembly. The trigger assembly can realize the step-by-step sequential movement of the first cutting assembly and the second cutting assembly. When cutting the waste roll, the trigger block squeezes the second stop rod to slide into the first movable groove to make the first movable block separate from the side position of the limit block. The fourth electric push rod drives the limit plate to move so that the sliding block is constrained by the fixed rod and slides accordingly. The first cutting plate cuts and disconnects the composite film. At this time, the first cutting assembly can be constrained by the trigger assembly to move;

[0023] When cutting and rewinding, the waste roller is close to the side position of the matching plate, the rotating rod rotates ninety degrees, the connecting rod is clamped in the slot, the first stop rod slides into the second movable slot, and squeezes the second movable block out of the side of the connecting rod. The rotating rod rotates to make the connecting rod slide out of the second movable slot, and the rotating rod rotates toward the side of the matching plate. At the same time, the fourth electric push rod pushes the rotating rod down so that the hot melt module fits the side position of the matching plate, and the trigger block is reset without squeezing. At this time, the electric slide drives the fourth electric push rod to slide so that the second cutting plate first cuts and disconnects the composite film on the side of the waste roller, and then the composite film on the side of the matching plate and the disconnected composite film are hot-melt bonded together. After the fourth electric push rod is in place, the rotating rod rotates to drive the connecting rod to slide into the second movable slot. At this time, the second cutting assembly is constrained to move by the trigger assembly; in this way, when used in different states, the trigger assembly can be used to switch the first cutting assembly and the second cutting assembly to cooperate in movement and use, so as to complete the removal of the waste segment of the composite film.

[0024] 4. The present invention sets a first cutting assembly, and the first movable block is sleeved on the position of the corresponding limit block pressure detection head under the elastic force of the first spring. The sliding block is constrained and limited, and the side of the limit block is subjected to force to obtain a signal feedback to the control cabinet. At this time, the control cabinet can effectively know the position of the first cutting board for use in subsequent operations.

[0025] 5. The present invention sets a second cutting assembly. After the connecting rod slides into the second movable groove, the second movable block is reset and connected to the side of the connecting rod. The rotating rod is rotated and reset to pull the connecting rod out of the slot. At this time, the connecting rod is close to the detection block so that it can get a signal feedback to the control cabinet. At this time, the control cabinet can effectively know the position of the second cutting board for use in subsequent operations.

[0026] 6. The present invention provides an auxiliary mechanism, so that when the waste roll is cut off, the composite film continues to be discharged. At this time, the first electric push rod pulls the fixed ring to make the movable roller slide inside the slide groove, so that the distance between the movable rollers slowly and continuously increases. At this time, the composite film is squeezed and clamped by the auxiliary rollers. Since the distance continues to increase, the composite film can continue to be discharged, ensuring that the film can be discharged without stopping when the waste roll is collected;

[0027] During cutting and rewinding, the movable roller is driven to move and the tension of the composite film can be adjusted to ensure the stable discharge of the composite film. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] Working principle:

[0053] Before use: Check all components for damage and turn on the power supply of control cabinet 1 to prepare for use;

[0054] When in use: the composite film 3 at the film outlet of the film forming machine is guided by the guide roller 21 and the movable roller 23 sideways, and is wound between the mounting plates 41 to the side of the automatic winding frame 12 for winding operation;

[0055] During normal winding, the automatic winding frame 12 performs winding operation on the composite film 3, and the first electric push rod 25 pushes the movable roller 23 to move and adjust the tension of the composite film 3 on its side. At the same time, the upper side mounting plate 41 is pulled away from the composite film 3 by the second electric push rod 42, and the lower side mounting plate 41 is pushed by the second electric push rod 42 so that the auxiliary roller 43 is attached to the side of the composite film 3 for auxiliary guidance, and the composite film 3 after the film is discharged is subjected to real-time online flaw detection by the flaw detector 26;

[0056] The flaw detection shows stratification and bubbles. When the waste roll is cut off, the waste section reaches the position of the mounting plate 41, and the second electric push rod 42 pushes the two sets of mounting plates 41 closer together so that the auxiliary rollers 43 are squeezed on the side of the composite film 3. The automatic winding frame 12 stops the winding operation. At this time, the third motor 68 drives the trigger block 67 to be squeezed on the side of the second stop rod 66, and the second stop rod 66 slides into the first movable groove 75 to squeeze the first movable block 76 out of the side position of the limit block 72. At the same time, the fourth electric push rod 52 pushes the rotating rod 53 vertically so that the hot melt module 55 squeezes the composite film 3 to fit on the side of the waste roller 45. The electric slide table 51 drives the fourth electric push rod 52 to slide, so that the limiting plate 61 drives the sliding block 73 to slide accordingly under the constraint of the fixed rod 71, and the first cutting plate 74 cuts and disconnects the composite film 3. After the operation, the composite film 3 breaks and falls to the side of the matching plate 56. At the same time, when the hot melt module 55 is heated, the composite film 3 is hot-melted and adhered to the side of the waste roller 45. After the electric slide 51 drives the fourth electric push rod 52 to the other side, the trigger block 67 rotates without squeezing, and the second stop rod 66 slides out of the first movable groove 75. The first movable block 76 is sleeved at the corresponding limit block 72 pressure detection head position under the elastic force of the first spring 77. The sliding block 73 is constrained and limited. The side of the limit block 72 is subjected to force and a signal is fed back to the control cabinet 1. Then the electric slide 51 drives the fourth electric push rod 52 to drive the limiting plate 61 to slide back to its original position. The hot melt module 55 further squeezes the composite film 3 to fit the side of the waste roller 45. At this time, the first motor 46 drives the waste roller 45 to rotate to perform a winding operation to collect the waste segment.

[0057] During cutting and rewinding, after the waste section is wound up, the third electric push rod 47 pushes the fixed frame 44 so that the waste roller 45 is close to the side position of the matching plate 56, and the second motor 54 drives the rotating rod 53 to rotate ninety degrees in the direction of the connecting rod 85, and the connecting rod 85 is clamped in the slot 87, and the first stop rod 65 slides into the second movable slot 82 to squeeze the second movable block 83 out of the side of the connecting rod 85, and the rotating rod 53 rotates to make the connecting rod 85 slide out of the second movable slot 82, and the rotating rod 53 rotates toward the side of the matching plate 56. At the same time, the fourth electric push rod 52 pushes the rotating rod 53 downward so that the hot melt module 55 is attached to the side position of the matching plate 56, and the trigger block 67 is reset and does not squeeze. At this time, the electric slide 51 drives the fourth electric push rod 52 slides so that the second cutting plate 88 first cuts and breaks the composite film 3 on the side of the waste roller 45, and then the composite film 3 on the side of the matching plate 56 and the broken composite film 3 are hot-melted and bonded together. After the fourth electric push rod 52 is in place, the rotating rod 53 rotates to drive the connecting rod 85 to slide into the second movable groove 82. The same operation is performed as above. After the connecting rod 85 slides into the second movable groove 82, the second movable block 83 is reset and connected to the side of the connecting rod 85. The rotating rod 53 rotates and resets to pull the connecting rod 85 out of the card slot 87. At this time, the connecting rod 85 is close to the detection block 86 so that it can get a signal feedback to the control cabinet 1. The upper side position mounting plate 41 is away from the composite film 3 position so that the automatic winding frame 12 can continue to perform normal winding operation;

[0058] Among them, in the above operation, when the waste roll is cut off, the composite film 3 is still in the film discharging operation. At this time, the first electric push rod 25 pulls the fixed ring 24 to make the movable roller 23 slide inside the slide groove 22, so that the distance between the movable rollers 23 slowly and continuously increases. At this time, the composite film 3 is squeezed and clamped by the auxiliary roller 43. Since the distance continues to increase, the composite film 3 can continue to be discharging film, ensuring that the film can be discharged without stopping when the waste roll is collected. After cutting off the rewinding, the winding operation can be accelerated by the automatic winding frame 12, and the first electric push rod 25 synchronously pulls the movable roller 23 to slowly and continuously shorten, and the normal operations of film making, film discharging and winding are continued.

[0059] 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.
