Description

Technical Field

[0001] The invention relates to the technical field of PTFE film production, in particular to hot pressing composite equipment for PTFE film production and a use method thereof. Background Art

[0002] The background technology of hot pressing composite equipment for PTFE membrane production mainly includes hot pressing process, temperature control technology, pressure control technology and material processing technology. These technologies are all to ensure that the PTFE membrane can be effectively combined with other materials to obtain a composite material with specific properties.

[0003] During the use of hot pressing composite equipment, most of the time, two material rolls are installed on the same side of the hot pressing composite equipment, so that the materials are transported to the inside of the hot pressing composite equipment for hot pressing composite. However, when the diameter of the material roll is relatively large, it is difficult to install the material roll on the conveyor rack, affecting the production of PTFE membrane. If the material roll is installed on the conveyor rack and causes the two material rolls to contact each other, it will affect the surface contact of the two material rolls and generate friction during the rotation process, making it difficult to transport them to the inside of the hot pressing composite equipment. When the friction is large, it will also cause damage to the surface of the material, thereby reducing the production quality of the PTFE membrane. Summary of the invention

[0016] A method for using a hot pressing composite device for producing a PTFE membrane comprises the following steps:

[0017] S1: two hydraulic cylinders are used to drive two sliding blocks to slide on the outer walls of two storage mounting frames, thereby pushing one end of two connecting strips on each sliding block to move forward, and pushing two feed roller mounting frames to rotate inside the rotating slot frames at the top and bottom of the connecting frames, respectively, so that the angle between the two connecting strips is increased, and then the material roll is installed on the two feed roller mounting frames;

[0018] S2: By connecting the winding roller mounting frame with the arc-shaped connecting strip, the extended tooth plate is driven to slide on the bottom of the bottom plate, so that the extended tooth plate moves in the direction where the material roll is located, thereby increasing the force of the bottom plate supporting the material roll in the direction;

[0019] S3: Pass one end of the two material rolls through the two tension rollers and the material discharging frame respectively, so that the surfaces of the two material sheets are in close contact with the outer wall of the tension roller, and the materials of the two material rolls are wound around the ends of the two hot pressing composite rollers away from each other to the rear of the hot pressing composite rollers, and then pass through the two hot pressing composite rollers, and the two hot pressing composite rollers are controlled by the control end to rotate between the two hot pressing frames, and the materials passing through the two hot pressing composite rollers are hot pressed and composited;

[0020] S4: The composite PTFE film passes through the discharge frame and the limit frame, and contacts the winding roller installed on the winding roller mounting frame, and the PTFE film is wound by the winding roller.

[0021] The present invention has the following beneficial effects:

[0022] (1) The present invention drives two sliding blocks to slide on the outer walls of two storage mounting frames respectively through two hydraulic cylinders, thereby pushing one end of the two connecting strips on each sliding block to move forward, and pushing the two feed roller mounting frames to rotate inside the rotating slot frames at the top and bottom of the connecting frames respectively, so that the angle between the two connecting strips increases, and the spacing between one end of the material rolls installed on the two feed roller mounting frames increases. The spacing between the installation positions of the two material rolls can be adjusted according to the diameter of the material rolls, thereby avoiding the difficulty in installing the material rolls on the feed roller mounting frames due to excessive size, which affects the production of PTFE membranes. After the material rolls are installed on the feed roller mounting frames, the phenomenon of the two material rolls contacting each other is avoided, thereby avoiding the large extrusion friction generated during the rotation process due to the contact between the surfaces of the two material rolls, which makes it difficult to transmit to the inside of the hot pressing composite equipment, and avoiding the phenomenon that the surface of the material is damaged when the friction force is large, thereby reducing the production quality of the PTFE membrane.

[0023] (2) After the present invention installs two material rolls inside the feed roller installation frame on the two sets of rotating slot frames, one end of the two material rolls can be passed through between the two tension rollers and the discharge frame respectively, so that the surfaces of the two material sheets are in close contact with the outer wall of the tension roller, thereby reducing the height of the material transmitted to the inside of the hot pressing mechanism, and facilitating the materials of the two material rolls to go around from the ends of the two hot pressing composite rollers away from each other to the back of the hot pressing composite rollers, and then pass through between the two hot pressing composite rollers. The two hot pressing composite rollers are controlled by the control end to rotate between the two hot pressing frames, and the materials passing through the two hot pressing composite rollers are hot pressed and composited. By passing the materials around to the back of the hot pressing composite rollers, the material can be increased. The contact area with the surface of the hot-pressing composite roller increases the heating time of the material, thereby improving the composite effect of the material. The composite PTFE film will pass through the discharge frame and the limit frame, and contact the wind-up roller installed on the wind-up roller mounting frame. The PTFE film is wound up by the wind-up roller. When the distance between the two feed roller mounting frames becomes larger, the sliding block is pushed forward inside the storage mounting frame, and the limit frame and the wind-up roller mounting frame are simultaneously driven forward between the two storage mounting frames, so that the wind-up roller installed on the wind-up roller mounting frame is away from one end of the material roll installed on the two feed roller mounting frames, so as to prevent the two material rolls from affecting the wind-up roller on the wind-up roller mounting frame to wind up the PTFE film.

[0024] (3) In the process of adjusting the spacing between one end of the material roll installed on the two feed roller mounting frames of the present invention, the connection between the winding roller mounting frame and the arc-shaped connecting strip will drive the extended tooth plate to slide on the bottom of the base plate, so that the extended tooth plate moves in the direction of the material roll, thereby increasing the force of the base plate supporting the material roll in the direction, avoiding the phenomenon that the large-diameter material roll exerts too much gravity on the feed roller mounting frame, causing the device to tip over due to the small contact area between the base plate and the ground, and in the process of adjusting the extended tooth plate, by pulling the support arm out of the positioning hole, the movable connection The frame rotates on the bottom plate, thereby driving the double-tooth sleeve to engage with the tooth grooves on the extended tooth plate, which can drive the double-tooth sleeve to rotate, and the connecting rod is driven by the belt to rotate inside the rotating connecting frame, and then the bidirectional lead screw is driven by the belt to rotate, so that the two lead screw sleeves are driven by the bidirectional lead screw to move relative to each other in the two moving holes respectively, thereby driving the movable slide and the hot pressing frame to move relative to each other, increasing the exposed area of ​​the two hot pressing composite rollers, and the exposed width of the hot pressing composite roller surface can be adjusted, so that materials with a larger width can be hot pressed and composited, thereby improving the practicability of the device.

[0025] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
