Description

Technical Field

[0001] The invention relates to the technical field of film production, and in particular to a deviation correction alarm device and method in a film production line. Background Art

[0002] After the metallized film is coated in the vacuum coating machine, a raw film with a large area and volume is formed. The raw film must be cut into several metallized film strips by a film slitting machine, and the metallized film strips are then rolled up to make metallized film rolls that meet the standards.

[0003] When the metallized film slitting machine is performing slitting operations, raw film unwinding is one of the necessary processes. The traditional raw film unwinding is to place the raw material roll on a fixed bracket, and the paper feed roller in front of it drives the unwinding. When the speed is fast, the unrolled metallized film will deviate. The existing technology mostly adopts a two-way fixed limit method for deviation correction and adjustment. However, in actual use, this adjustment method will cause damage to the film, and it cannot be adapted, the adjustment is not timely, and the defective rate is high. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] The four corners of the upper surface of the bottom plate 1 are fixedly connected with columns 2, and a winding roller 9 for winding the film is arranged between the columns 2. The moving mechanism 3 is arranged on the top of the columns 2, and drives the adjusting mechanism 4 to perform horizontal reciprocating movement.

[0040] Two adapting mechanisms 5 that move toward each other and adapt to the film are arranged at the bottom of the adjusting mechanism 4, and two clamping plates 6 that move toward each other and limit the film are arranged on one side of a single adapting mechanism 5.

[0041] In the above structure, the adjusting mechanism 4 moves the clamping plate 6 inwards and limits the film on both sides. At the same time, the adapting mechanism 5 drives the clamping plate 6 to move toward each other and limits the film up and down.

[0042] It also includes a buffer mechanism 7 and a pressure sensor 8 for transmitting a deviation correction alarm signal to the position of the film. The pressure sensor 8 is arranged on the buffer mechanism 7. The alarm 10 is arranged on one side of the column 2 and is electrically connected to an external controller.

[0043] In the above structure, during the correction process, when the offset of the metal film is large, the pressure sensor 8 senses the force and controls the alarm 10 through the external controller to sound an alarm, thereby realizing real-time monitoring and alarm functions of the film position, improving production efficiency and product quality.

[0046] Step 2: Control the adapting mechanism 5 to drive the clamping plates 6 to move toward each other to limit the upper and lower positions of the film;

[0047] Step 3: Control the movement mechanism 3 to make the clamping plate 6 move back and forth horizontally, thereby correcting the film in the winding process in real time.

[0048] Embodiment 2:

[0049] like Figure 1-7 As shown, an embodiment of the present invention provides a deviation correction alarm device in a film production line, including a base plate 1, a moving mechanism 3, an adjustment mechanism 4, an adaptation mechanism 5 and an alarm 10.

[0050] The four corners of the upper surface of the bottom plate 1 are fixedly connected with columns 2, and winding rollers 9 for winding the film are arranged between the two columns 2. The moving mechanism 3 is arranged on the top of the column 2, and it drives the adjustment mechanism 4 to perform horizontal transverse reciprocating movement. Specifically, the moving mechanism 3 includes a top frame 31 fixedly connected to the top of the column 2, and a driving motor 32 is arranged on the outer surface of the top frame 31. The output end of the driving motor 32 passes through the inside of the top frame 31 and is fixedly connected with a reciprocating screw 33. The outer wall of the reciprocating screw 33 is threadedly connected with a moving block 34, and the adjusting mechanism 4 is fixedly connected to the bottom of the moving block 34;

[0051] The above structure, through the driving action of the driving motor 32, drives the reciprocating screw 33 to rotate, and then drives the moving block 34 and the adjusting mechanism 4 to perform horizontal reciprocating movement.

[0052] Two adapting mechanisms 5 that move toward each other and adapt to the film are provided at the bottom of the adjusting mechanism 4. Specifically, the adjusting mechanism 4 includes a moving frame 41 fixedly connected to the bottom of the moving block 34.

The outer walls at both ends of the first bidirectional threaded rod 43 are threadedly connected to a first threaded block 44. The two adapting mechanisms 5 are correspondingly fixedly connected to the bottom of the first threaded block 44.

[0053] In the above structure, by rotating the first knob 42, the first bidirectional threaded rod 43 is driven to rotate, thereby driving the two first threaded blocks 44 and the adapter mechanism 5 to move synchronously and toward each other.

[0054] One side of a single adapter mechanism 5 is provided with two clamps 6 that move toward each other and limit the film. Specifically, the adapter mechanism 5 includes an adapter plate 51 fixedly connected to the bottom of the first threaded block 44, and the bottom of the adapter plate 51 is rotatably connected to a second knob 52, one end of the second knob 52 passes through the interior of the adapter plate 51 and is fixedly connected to a second bidirectional threaded rod 53, and the outer walls at both ends of the second bidirectional threaded rod 53 are threadedly connected to the second threaded block 54, the clamp 6 is fixedly connected to the outer side of the second threaded block 54, and the inner side of the clamp 6 is provided with a plurality of balls 61 for lubricating the film.

[0055] The above structure drives the second bidirectional threaded rod 53 to rotate by rotating the second knob 52, thereby driving the two second threaded blocks 54 and the clamping plate 6 to move synchronously and toward each other, thereby limiting the upper and lower positions of the film.

The alarm 10 is arranged on one side of the column 2 and is electrically connected to the external controller.

[0057] In the above structure, during the correction process, when the offset of the metal film is large, the pressure sensor 8 senses the force and cooperates with the compression of the spring 72, and controls the alarm 10 through the external controller to sound an alarm, thereby realizing real-time monitoring and alarm functions of the film position, improving production efficiency and product quality.

[0058] The embodiment of the present invention also provides a method for using a deviation correction alarm device in a film production line, comprising the following steps:

[0059] Step 1: Wind the film to be produced on the winding rollers 9 on both sides, turn the first knob 42, drive the first bidirectional threaded rod 43 to rotate, and then drive the two first threaded blocks 44 and the adapter mechanism 5 to move synchronously and toward each other, so that the clamping plate 6 moves inward, and the film is limited on both sides;

[0060] Step 2: Rotate the second knob 52 again to drive the second bidirectional threaded rod 53 to rotate, thereby driving the two second threaded blocks 54 and the clamping plate 6 to move synchronously and toward each other, and the film is limited up and down by the ball 61;

[0061] Step 3: Turn on the power of the driving motor 32, and through the driving action of the driving motor 32, drive the reciprocating screw 33 to rotate, thereby driving the moving block 34 and the adjusting mechanism 4 to move horizontally back and forth, so that the clamping plate 6 moves horizontally back and forth, thereby correcting the film in the winding process in real time;

[0062] Step 4: During the correction process, when the offset of the metal film is large, the pressure sensor 8 senses the force and cooperates with the compression of the spring 72, and controls the alarm 10 through an external controller to sound an alarm, thereby realizing real-time monitoring and alarm functions of the film position, improving production efficiency and product quality.
