Description

Technical Field

[0001] This utility model relates to the field of multi-layer co-extrusion casting machine technology, and more specifically, to a multi-layer co-extrusion casting machine for high-temperature release film. Background Technology

[0002] High-temperature release film is a special functional film that can maintain stable performance in high-temperature environments. It is mainly used to isolate adhesive materials (such as adhesives, resins, etc.) and can be easily peeled off without residue when needed. Multilayer co-extrusion casting machine is a high-end equipment used to produce multilayer composite films. It forms films with specific functions by simultaneously extruding and compounding different materials.

[0003] Traditional multilayer co-extrusion casting machines for high-temperature release films have the following shortcomings: In operation, multiple extruders heat and plasticize different materials separately. The melts are then layered and composited within the die to form a multilayer structure. The molten film is rapidly cooled and shaped by cold rollers before subsequent winding, slitting, or surface treatment operations. Installing a detachable cylinder on the outside of the roller is a key design to optimize the winding process. Its core purpose is to solve the adhesion problem caused by direct contact between the film roll and the equipment, while improving operating efficiency and product quality. However, after long-term use, the cylinder may deform due to fatigue or impact, resulting in a mismatch between the cylinder and the roller, making it difficult to remove the cylinder from the roller. Therefore, improvements are needed. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a multi-layer co-extrusion casting machine for high-temperature release film, which has the advantage of easy winding.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multilayer co-extrusion casting machine for high-temperature resistant release film, comprising a platform, an extruder disposed above the platform, a side plate one and a side plate two bolted to the left end of the platform respectively, a cooling roller assembly disposed between the inner sides of the side plate two, a winding mechanism disposed on the inner side of the left end of the side plate two, the winding mechanism comprising a disc rotatably mounted inside the side plate two, a circular roller bolted to the inner side of the disc, a circular groove being formed inside the circular roller, through grooves extending to the outer side of the circular roller being formed on both sides of the circular groove, an elliptical roller being rotatably mounted at one end inside the circular groove, an arc panel being slidably mounted inside the through groove, a gear one welded to the other end of the elliptical roller, and a gear one meshing with a gear two being rotatably mounted on the inner side of the disc.

[0006] As a preferred technical solution of this utility model, a positioning block 1 is welded above the inner end of the arc panel on one side, and a positioning mechanism is provided at the outer end of the arc panel. The positioning mechanism includes a sliding groove opened inside the arc panel, and a positioning block 2 is slidably installed inside the sliding groove. The top end of the positioning block 2 extends to the outer side of the arc panel, and a telescopic spring is elastically installed between the inner side of the positioning block 2 and the inner side of the sliding groove.

[0007] As a preferred embodiment of this utility model, a mounting bracket is welded to the outer side of the second side plate, and a second servo motor is bolted between the inner sides of the mounting bracket. The output end of the second servo motor is bolted to the other end of the disc.

[0008] As a preferred embodiment of this utility model, a servo motor is bolted to the outer side of the disk, and the output end of the servo motor passes through the disk and is bolted to the inner side of the gear.

[0009] As a preferred embodiment of this utility model, a limiting groove is provided on the inner side of the through groove, and a limiting block that is slidably connected inside the limiting groove is welded to the outer side of the arc panel.

[0011] As a preferred technical solution of this utility model, sliders are welded to both sides of the bottom of the second positioning block, and the sliders are slidably connected inside the groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses an elliptical roller to press the inner arc surface of the arc panel, thereby increasing the diameter of one end of the round roller.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 6As shown, this utility model provides a multi-layer co-extrusion casting machine for high-temperature release film, including a platform 1, an extruder 2 arranged on the top of the platform 1, a side plate 3 and a side plate 4 bolted to the left side of the platform 1 respectively, a cooling roller group 5 arranged between the inner sides of the side plate 4, a winding mechanism 6 arranged on the inner side of the left end of the side plate 4, the winding mechanism 6 including a disc 601 rotatably installed inside the side plate 4, a roller 602 bolted to the inner side of the disc 601, a circular groove 603 opened inside the roller 602, through grooves 604 extending to the outer side of the roller 602 on both sides of the circular groove 603, an elliptical roller 605 rotatably installed at one end of the circular groove 603, an arc panel 607 slidably installed inside the through groove 604, a gear 608 welded to the other end of the elliptical roller 605, and a gear 608 meshing with a gear 609 rotatably installed on the inner side of the disc 601.

[0024] Among them, a mounting bracket 613 is welded to the outer side of the second side plate 4, and a servo motor 614 is bolted between the inner sides of the mounting bracket 613. The output end of the servo motor 614 is bolted to the other end of the disc 601.

[0025] Among them, a servo motor 612 is bolted on the outer side of the disc 601. The output end of the servo motor 612 passes through the disc 601 and is bolted to the inner side of the gear 608. A limiting groove 610 is opened on the inner side of the through groove 604. A limiting block 611 is welded to the outer side of the arc panel 607 and is slidably connected to the inside of the limiting groove 610. The length of the elliptical roller 605 is equal to the length of the arc panel 607. The gear 608 and the gear 609 match in the vertical direction.

[0026] During the winding operation, one end of the film roll is first wound around the outside of the winding mechanism 6. At this time, the longer end of the elliptical roller 605 is placed inside the through groove 604, so that the elliptical roller 605 squeezes the inner arc surface of the arc panel 607, causing the arc panel 607 to expand outward, thereby increasing the diameter of one end of the circular roller 602. At this time, the servo motor 614 is started, which drives the disc 601 to rotate. The disc 601 drives the circular roller 602 to rotate, so that the circular roller 602 performs winding. During the winding operation, after the winding operation is completed, the servo motor 612 is started, which drives the gear 608 to rotate. The gear 608 drives the gear 609 to rotate, so that the shorter end of the gear 609 rotates to the inside of the through groove 604. At this time, the cylinder releases its elastic potential energy to squeeze the arc panel 607, causing the arc panel 607 to shrink into the inside of the circular groove 603. At this time, the radius of the roller 602 returns to its original shape, making it easy to remove the cylinder. The cylinder is made of elastic material.

[0027] The elliptical roller 605 presses the inner arc surface of the arc panel 607, thereby increasing the diameter of one end of the circular roller 602. After the winding operation is completed, the shorter end of the gear 609 is rotated to the inner side of the through groove 604, so that the radius of the circular roller 602 returns to its original shape. Compared with the traditional multi-layer co-extrusion casting machine for high-temperature release film, this multi-layer co-extrusion casting machine for high-temperature release film has the advantage of assisting unloading by changing the radius of the circular roller 602, making it easier for workers to take the film roll out from the outside of the circular roller 602 and making it convenient for use.

[0028] A positioning block 606 is welded to the upper inner end of one side of the arc panel 607. A positioning mechanism 7 is provided at the outer end of the arc panel 607. The positioning mechanism 7 includes a groove 71 opened inside the arc panel 607. A positioning block 72 is slidably installed inside the groove 71. The top of the positioning block 72 extends to the outer side of the arc panel 607. A telescopic spring 73 is elastically installed between the inner side of the positioning block 72 and the inner side of the groove 71. Slider blocks 74 are welded to both sides of the bottom of the positioning block 72. The sliders 74 are slidably connected inside the groove 71.

[0029] When the cylinder is installed on the outside of the roller 602, it is first inserted inward by placing the cylinder on the outside of the roller 602, so that the cylinder presses against the arc surface of the second positioning block 72. The second positioning block 72 is compressed by the compressive force and shrinks into the inside of the slide groove 71, so that the second positioning block 72 presses against the telescopic spring 73, causing the telescopic spring 73 to deform. At this time, the slider 74 moves with the second positioning block 72 inside the slide groove 71, thereby limiting the second positioning block 72. When one end of the cylinder reaches the inside of the first positioning block 606, the other end of the cylinder is removed from the top of the second positioning block 72. At this time, the telescopic spring 73 releases its elastic potential energy to push the second positioning block 72 back to its original position, thereby limiting the cylinder. When it needs to be removed, simply press the second positioning block 72 and remove the cylinder.

[0030] By pressing the arc surface of positioning block 72 with a cylinder, positioning block 72 is retracted into the interior of the groove 71. When one end of the cylinder reaches the inner side of positioning block 606, positioning block 72 returns to its original position to limit the cylinder. Compared with traditional multi-layer co-extrusion casting machines for high-temperature release films, this multi-layer co-extrusion casting machine for high-temperature release films limits the cylinder with positioning block 72 and positioning block 606, thereby improving the stability during winding.

[0031] Working principle and usage process of this utility model:

[0032] During the winding operation, one end of the film roll is first wound around the outside of the winding mechanism 6. At this time, the longer end of the elliptical roller 605 is placed inside the through groove 604, so that the elliptical roller 605 squeezes the inner arc surface of the arc panel 607, causing the arc panel 607 to expand outward, thereby increasing the diameter of one end of the circular roller 602. At this time, the second servo motor 614 is started, which drives the disc 601 to rotate. The disc 601 drives the circular roller 602 to rotate, so that the circular roller 602 performs the winding operation. After the winding operation is completed, the first servo motor 612 is started, which drives the first gear 608 to rotate. The first gear 608 drives the second gear 609 to rotate, so that the shorter end of the second gear 609 rotates to the inside of the through groove 604. At this time, the cylinder releases elastic potential energy to squeeze the arc panel 607, causing the arc panel 607 to shrink into the inside of the circular groove 603. At this time, the radius of the circular roller 602 returns to its original shape, so that the cylinder can be easily removed.

[0033] When the cylinder is installed on the outside of the roller 602, it is first inserted inward by placing the cylinder on the outside of the roller 602, so that the cylinder presses against the arc surface of the second positioning block 72. The second positioning block 72 is compressed by the compressive force and shrinks into the inside of the slide groove 71, so that the second positioning block 72 presses against the telescopic spring 73, causing the telescopic spring 73 to deform. At this time, the slider 74 moves with the second positioning block 72 inside the slide groove 71, thereby limiting the second positioning block 72. When one end of the cylinder reaches the inside of the first positioning block 606, the other end of the cylinder is removed from the top of the second positioning block 72. At this time, the telescopic spring 73 releases its elastic potential energy to push the second positioning block 72 back to its original position, thereby limiting the cylinder. When it needs to be removed, simply press the second positioning block 72 and remove the cylinder.
