Description
Technical Field
[0001] The invention relates to the technical field of polytetrafluoroethylene plate processing equipment, in particular to a compression molding equipment for processing polytetrafluoroethylene plates. Background Art
[0002] Polytetrafluoroethylene, also known as Teflon, is commonly known as the "King of Plastics". It is a high molecular polymer made from tetrafluoroethylene as a monomer, and has excellent heat and cold resistance. This material is resistant to acids, alkalis, and various organic solvents, and is almost insoluble in all solvents. At the same time, polytetrafluoroethylene has the characteristics of high temperature resistance and its friction coefficient is extremely low, so it can be used as a lubricant and has also become an ideal coating for the inner layer of easy-to-clean water pipes.
[0003] In the field of PTFE sheet processing, traditional processing methods often have some limitations, which directly affect production efficiency, cost control and product quality. Specifically, when processing PTFE sheets, traditional equipment has high production and maintenance costs due to the complexity of structural design. In addition, these equipment often require manual intervention during operation, which not only reduces production efficiency but also increases the possibility of human error.
[0004] During the processing, accuracy is a key factor that directly affects the quality of the product and the complexity of subsequent processing. Traditional equipment lacks an effective limit mechanism, making it difficult to ensure that the upper and lower platens remain in the same vertical plane during processing, which may cause the molten polytetrafluoroethylene liquid to penetrate outward and form thicker flash, thereby increasing the workload and cost of subsequent processing.
[0005] In addition, the traditional equipment lacks effective buffering and separation mechanisms during the forming and separation of PTFE sheets, which easily leads to shape distortion or cracking of PTFE sheets during separation, affecting the performance and appearance of the product. The existence of these problems has made it urgent to innovate and improve the processing technology of PTFE sheets in order to achieve cost-effectiveness, efficiency improvement and product quality optimization.

[0015] Preferably, a slide groove is provided on the middle outer surface of the mounting tube, an auxiliary tube is arranged inside the mounting tube, the bottom of the auxiliary tube is fixedly connected to the upper surface of the lower pressure plate, the top outer surface of the auxiliary tube is provided with an air outlet groove, the top outer surface of the auxiliary tube is slidably sleeved with a movable tube, the bottom outer surface of the movable tube is fixedly connected to the extrusion plate through the slide groove, the auxiliary tube is initially arranged on the outside of the air outlet groove, the bottom of the auxiliary tube is connected to the internal cavity of the corrugated tube, when the polytetrafluoroethylene particles are placed on the lower pressure plate, they will be on the inner side of the isolation plate in the mounting frame, when the polytetrafluoroethylene particles are melted and solidified, as the upper pressure plate moves upward, the pulling strip on its bottom surface will first be pushed upward through the side plate, and at this time, the bottom surface of the pressing plate is attached to the upper surface of the formed polytetrafluoroethylene plate and is in a sticky state, as the pulling strip moves upward, the end of the pulling strip away from the side plate pulls the extrusion plate downward, and then pulls the first bottom plate downward.
[0016] The present invention provides a compression molding device for processing polytetrafluoroethylene plates. It has the following beneficial effects: 1. The compression molding equipment for processing polytetrafluoroethylene sheets greatly reduces the cost of producing polytetrafluoroethylene sheets and reduces maintenance costs through a simple structural setting. At the same time, the full-automatic method greatly improves production efficiency. At the same time, through the limiting effect of the first working rod and the second working rod, the upper pressing plate and the lower pressing plate are always in the same vertical plane, thereby greatly improving the accuracy of polytetrafluoroethylene sheet production, avoiding the problem of misalignment between the upper pressing plate and the lower pressing plate, resulting in the infiltration of molten polytetrafluoroethylene liquid to produce thicker flash, and increasing a large amount of post-processing work.
[0017] 2. In the compression molding equipment for processing polytetrafluoroethylene plates, when the first bottom plate moves downward, the mounting plate on its side surface will move downward synchronously, thereby squeezing the buffer plate. Since the width of the first buffer groove is smaller than that of the second buffer groove, the second bottom plate will be gradually pulled downward as the first bottom plate moves downward, and finally the third bottom plate will be pulled downward, so that the first bottom plate, the second bottom plate and the third bottom plate are gradually separated from the contact with the bottom surface of the polytetrafluoroethylene plate. By separating in sequence, the pulling force on the bottom surface of the polytetrafluoroethylene plate is greatly reduced, and the possibility of the polytetrafluoroethylene plate being deformed or cracked when the polytetrafluoroethylene plate is separated is greatly reduced.
[0018] 3. The die-casting equipment for processing polytetrafluoroethylene plates will extrude the bellows during the downward movement of the extrusion plate, and pull the movable tube in the mounting tube to move downward. As the movable tube moves downward, the air outlet groove on the auxiliary tube will gradually open. Initially, the bellows will be squeezed first, and the internal air pressure will be in a compressed state. As a result, when the air outlet groove on the auxiliary tube is opened, the high-pressure gas will be instantly released through the air outlet groove, and then released to the bottom surface of the polytetrafluoroethylene plate through the mounting tube, providing a reverse thrust for the bottom surface of the polytetrafluoroethylene plate, which can not only accelerate the detachment of the bottom surface of the polytetrafluoroethylene plate, but also reversely buffer the bottom surface of the polytetrafluoroethylene plate, so as to avoid excessive deformation of the polytetrafluoroethylene plate when it is pulled by the first bottom plate, the second bottom plate and the third bottom plate, resulting in cracking or shape distortion that affects the performance of the polytetrafluoroethylene plate.
