Description

A production process of flame-retardant magnetic film

Technical field

The invention relates to the technical field of film production, specifically a production process for flame-retardant magnetic films.

Background technique

Flame-retardant magnetic adsorption film is a special magnetic adsorption material. It is mainly made of flame-retardant materials. Therefore, it can effectively inhibit spontaneous combustion and the occurrence of fire. It is suitable for high temperature and flammable environments. At the same time, because the flame-retardant magnetic adsorption film has It has a unique magnetic attraction effect, so it can be adsorbed on various metal surfaces, making it easy to use and install.

When manufacturing flame-retardant magnetic film, the glue is mainly mixed with acrylic resin, nano-alumina and magnetic powder, and added with auxiliary materials such as flame retardants and catalysts. The glue is solidified at high temperature through the mold to obtain the film raw materials, and then the film is processed The raw materials are cut and trimmed to finally obtain the required flame-retardant magnetic film. According to the shape and size of the required film, the film raw materials are cut and trimmed during the cutting and trimming process to obtain the required shape or size. size film.

Flame-retardant magnetic films are usually round or square. There are the following problems in the production process of square flame-retardant magnetic films: 1. When cutting the film raw materials, the film raw materials need to be supported or flattened. This keeps the film raw material in a flat state during cutting, preventing the area of the film that needs to be cut from being non-flat, making subsequent cutting difficult, and at the same time, the size error of the cut film is large and difficult to use.

2. During the cutting process, the four sides of the film raw material that need to be cut are not pressed tightly, which may easily cause the film raw material to shift during the subsequent cutting process, resulting in the shape and size of the cut film not meeting the requirements, and the need for cutting square films. After controlling and setting the length and width of the film, multiple cutting operations are performed to obtain a square film. The overall operation process has many steps and is inconvenient for manual operation.

When working, first manually take out the film raw material formed after high-temperature solidification in the mold in step S2, and control the operation of the two first cylinders 302 at the front and rear according to the required film size, so the telescopic end of the first cylinder 302 drives the cylinder plate to move, so The cylinder plate drives the moving plate 301 and the lower supporting plate 303 on it to move synchronously through the corresponding telescopic rod 300, so that the distance between the two lower supporting plates 303 is the required width of the film, and between the two lower supporting plates During the movement of 303, the second scale rod 340 slides in the receiving groove on the fixed block 341. Therefore, observing the scale on the second scale rod 340 at this time can obtain the specific value of the distance between the two lower supporting plates 303, so it is convenient for subsequent cutting. The width of the rear film is controlled.

After the two lower supporting plates 303 move, the two sliding plates 304 are manually moved respectively. The sliding plate 304 drives the square block 332 to move synchronously through the corresponding round rod 331. Therefore, the square block 332 drives the scale rod 333 on it to move in the through slot. Therefore, the distance between the two sliding plates 304 is obtained according to the scale on the scale rod 333. At the same time, the nut and the corresponding bolt 307 are tightened through the cooperation, so the distance between the sliding plate 304 and the lower supporting plate 303 is The distance between the two sliding plates 304 is fixed, that is, the distance between the two sliding plates 304 is the length of the film obtained by subsequent cutting, and observing the scale on the scale rod 333 at this time can obtain the distance between the two sliding plates 304, so it is convenient for subsequent cutting. The length of the film is controlled. At the same time, support plates 305 of different lengths are placed and installed by placing circular troughs, and a round table 351 is provided to support the film raw material, so as to avoid the occurrence of cutting caused by the sinking of the middle position of the film raw material due to its own gravity. The problem of increased size error of the obtained film ensures the subsequent support effect of the film raw materials.

Afterwards, the film raw materials are manually placed on the lower supporting plate 303. At this time, the lower supporting plate 303 and the supporting plate 305 cooperate with each other to support the original film. The electric slider 2 drives the corresponding lower pressing plate 313 downward through the transverse plate 312. Move, so the T-shaped structure of the lower pressing plate 313 cooperates with the lower supporting plate 303 and the supporting plate 305, so the placed film raw material is compressed, and the rubber strip 36 is deformed during the compressing process, so the increase in The friction between the film raw material and the lower pressing plate 313, the lower supporting plate 303 and the supporting plate 305 is eliminated, thereby avoiding the problem of the film raw material sliding during the subsequent cutting process.

And after the subsequent cutting is completed, the telescopic guide rod 353 works and its telescopic end drives the movable column to move upward, so the movable column drives the lifting plate 352 to move upward, that is, the lifting plate 352 drives the cut film to move upward, so that the cut film can be manually moved. take out.

As shown in Figures 2 and 8, the cutting mechanism 4 includes a mounting plate 40.

The other end of the scroll spring 432 is fixedly connected to the L-shaped plate 411 through the connecting column.

As shown in Figure 5, the lower pressure plate 313 has a T-shaped structure, and the two lower pressure plates 313 are symmetrically distributed in the center. The upper end surface of the lower pressure plate 313 is provided with a cutting groove 44 that runs through itself, and the cutting groove 44 is cross-shaped. The upper end surfaces of each lower supporting plate 303 are each provided with matching grooves 45 that cooperate with the corresponding cutting grooves 44 .

During operation, when the film raw material is pressed and limited, the traverse plate 312 drives the installation plate 40 to move synchronously. The cutting components on the rear side will be explained. The three electric sliders on the rear side drive the L-shaped plate 411 to move downward. Therefore, The L-shaped plate 411 drives the track plate 412 and the erected block to move downward simultaneously, so that the No. 1 cutting knife 415 and the No. 2 cutting knife 422 move downward simultaneously to the corresponding cutting groove 44, and at this time, the No. 1 cutting knife 415 is located on the lower platen. The left part in the upper cutting groove 44 of 313 and the lower end of the No. 1 cutting knife 415 are located in the matching groove 45. The No. 2 cutting knife 422 cuts into the film raw material. Then the electric slider 4 drives the connecting rod 414 to move to the right, so the connection The rod 414 drives the No. 1 cutting knife 415 to cut the film raw material from left to right. And in the process of the connecting rod 414 moving to the right, the connecting rod 414 drives one end of the rope 431 to move to the right, so the winding roller 430 rotates, and the winding roller 430 drives the threaded rod 420 to rotate synchronously, and the threaded rod 420 communicates with the moving bar. 421, the threads cooperate, so the moving bar 421 moves forward, and the moving bar 421 drives the No. 2 cutting knife 422 to cut the film raw material from back to front, so the two cutting parts perform cutting operations at the same time to complete the film raw material. The cutting operation is carried out so that the cut film is of the set size, and then the film after cutting is manually taken out.

When the connecting rod 414 drives the corresponding No. 1 cutting knife 415 to move and rotates the winding roller 430 and the threaded rod 420, the scroll spring 432 is wound and deformed. When the connecting rod 414 drives the No. 1 cutting knife 415 to complete After a single cut and reset, the connecting rod 414 and the rope 431 have no force on the winding roller 430 to rotate, so the force generated by the deformation of the scroll spring 432 causes the winding roller 430 to reverse, so the winding roller 430 rotates. The roller 430 winds the rope 431 and drives the threaded rod 420 to rotate in reverse. Through the threaded cooperation between the threaded rod 420 and the connecting bar, the connecting bar moves and resets, so that the next cutting operation is facilitated while the first cutting knife 415 and the second cutting knife 415 are used. The No. 1 cutting knife 422 cuts the film raw material during the resetting process, thereby avoiding the problem of adhesion in uncut areas during the cutting process.

During specific operation, first the front and rear first cylinders 302 work, so the telescopic end of the first cylinder 302 drives the cylinder plate to move, so the cylinder plate drives the moving plate 301 and the lower supporting plate 303 thereon to move synchronously through the corresponding telescopic rod 300 , manually move the two sliding plates 304 respectively, and at the same time tighten them through the cooperation between the nuts and the corresponding bolts 307, so the sliding plates 304 and the lower supporting plate 303 are fixed, and the circular grooves are placed to install different lengths. Supporting plate 305.

After that, the film raw material is placed on the lower supporting plate 303 and the supporting plate 305, and the two electric sliders work to drive the corresponding lower pressing plate 313 to move downward through the traverse plate 312.

When the film raw material is compressed and limited, the L-shaped plate 411 drives the track plate 412 and the vertical plate to move downward simultaneously, and the No. 1 cutting knife 415 and the No. 2 cutting knife 422 move downward simultaneously to the corresponding cutting groove 44, and then the electric slide The work of block 4 drives the connecting rod 414 to move to the right, so the connecting rod 414 drives the No. 1 cutting knife 415 to cut the film raw material from left to right, and through the work of the driving group 43, the No. 2 cutting knife 422 cuts from back to front.
