Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of medical composite material production and processing, specifically to a continuous hot-pressing composite equipment for medical composite materials. Background Technology
[0002] In the medical field, composite materials are increasingly widely used due to their excellent biocompatibility, mechanical properties, and designability. Traditional composite material molding processes, such as hand lay-up, compression molding, filament winding, pultrusion, autoclave molding, and resin transfer molding, have many drawbacks. Taking the autoclave process for ordinary thermosetting composites as an example, its curing and post-processing times are lengthy, and the manual lay-up process is not only labor-intensive, consuming significant time and manpower costs, but also makes it difficult to guarantee consistent product quality. In the manufacture of medical composite products, these problems can lead to low production efficiency, failing to meet the medical industry's demand for rapid product supply. Furthermore, the uncertainty introduced by manual operation can also affect product quality, thereby threatening patient safety. In addition, while continuous fiber-reinforced thermoplastic resin-based composites have the potential to be cured in-situ quickly without autoclave curing, processing requires high temperatures to melt the resin, demanding extremely high control over the effects of heat and stress at the interface. Therefore, it is urgent to develop a continuous hot-pressing composite equipment for medical composite materials. This equipment needs to be efficient, precise, and stable, enabling continuous production of composite materials, effectively solving the pain points of traditional processes, improving the quality and production efficiency of medical composite products, and meeting the ever-growing needs of the medical industry.
[0003] Application number CN201821354473.1 discloses a medical composite material comprising, in sequence, a surface coating, a nonwoven fabric layer, a disinfection and antibacterial layer, a fiber filter layer, a connecting layer, and a fiber cloth layer; wherein the surface coating, nonwoven fabric layer, disinfection and antibacterial layer, fiber filter layer, connecting layer, and fiber cloth layer are bonded together by hot pressing; the surface coating is coated on the nonwoven fabric layer and is a titanium dioxide coating; the nonwoven fabric layer is a composite of spunbond nonwoven fabric and activated carbon nonwoven fabric; the disinfection and antibacterial layer is a bamboo fiber layer; the fiber filter layer is a nanofiber filter layer; the connecting layer is a linen layer; and the fiber cloth layer is a natural cotton fiber layer. The medical composite material of this invention has good antibacterial and breathable properties due to the multiple composite layers, and can be used as a material for medical products such as masks, gauze, and sanitary clothing. However, there is a shortcoming: when the device is used, it is not yet able to adjust the pressing of composite materials of different thicknesses, which limits the scope of application of this device when hot pressing.

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.
[0025] Please see Figures 1-4 As shown, this utility model is a continuous hot pressing composite equipment for medical composite materials, including a support assembly 1.

The top of the adjusting support rod 502 is limited and installed with a fixed end 503. The middle of the adjusting support rod 502 is connected to a pneumatic telescopic rod two 505 via a hinge. The other side of the pneumatic telescopic rod two 505 is connected to the inner wall of the support box two 102 via a hinge.
[0027] By installing the adjustable pressing shaft assembly 5 on the device, the spacing between the rollers can be adjusted when using the device for composite materials of different thicknesses. This allows for different application scenarios and makes the device more widely applicable.
[0028] The bracket assembly 1 includes a support box 101, and a support box 2 102 is provided on the other side of the support box 101. The support box 101 and the support box 2 102 are of the same size and specifications.

[0029] The heating reel assembly 2 includes a pneumatic telescopic rod 201, which is hinged to the top of the inner wall of the support box 102. A movable support rod 202 is hinged to the end of the pneumatic telescopic rod 201. A slide rail 203 is mounted on the top of the movable support rod 202. A heating pump head 204 is mounted on the top of the slide rail 203. A positioning shaft 205 is correspondingly provided at the air outlet of the heating pump head 204. One side of the positioning shaft 205 is mounted on the support box 102.

The medical materials to be laminated, such as films and non-woven fabrics, enter from the rear of the equipment, are guided by the positioning shaft 205, and enter the heating area. After preheating, the heating pump head 204 adjusts its position through the slide rail 203 to heat the material evenly so that it reaches the appropriate temperature for lamination. The pneumatic telescopic rod 201 can adjust the height of the movable support rod 202 to accommodate materials of different thicknesses.
[0030] The hot press roller assembly 3 includes a rotary motor 301, which is fixedly installed inside the support box 101.

The transmission assembly 4 ensures that the hot pressing shaft 304 and the driven shaft 404 operate synchronously through the gear chain mechanism 401-404 to avoid material stretching and deformation.
[0032] An air-expansion shaft fixing shaft 504 is installed between the two fixed ends 503. The composite material enters the adjusting and pressing shaft assembly 5.

The adjusting pressing shaft assembly 5 controls the tension and pressing degree of the composite material, ensuring uniformity. The transmission assembly 4 coordinates the movement of each roller, guaranteeing continuous material transport and synchronous composite. In the specific operation, material transport is first required. Medical materials to be composite, such as films and non-woven fabrics, enter from the rear of the equipment, are guided by the positioning shaft 205, and enter the heating area for preheating. The heating pump head 204, positioned via the slide rail 203, uniformly heats the material to a suitable composite temperature. The pneumatic telescopic rod 201 adjusts the height of the movable support rod 202 to accommodate materials of different thicknesses. Afterward, the hot-pressing composite process can begin, with the preheated material being fed into… The hot press roller assembly 3, driven by a rotary motor 301, rotates the transmission rod 303, which in turn rotates the hot press roller 304 to apply pressure to the material. A limiting pressure plate 305 ensures uniform pressure distribution, preventing material shifting or wrinkling. The composite material then enters the adjusting pressing shaft assembly 5. A pneumatic telescopic rod 505 adjusts the height of the air expansion shaft fixed shaft 504 via an adjusting support rod 502, controlling material tension. This assembly can adapt to different material shrinkage rates, ensuring no bubbles or peeling between composite layers. The transmission assembly 4, through a gear chain mechanism 401-404, ensures synchronous operation of the hot press roller 304 and the passive shaft 404, preventing material stretching and deformation. The composite material can be naturally cooled or shaped by an auxiliary cooling roller, and finally collected by a winding device. This modified device achieves automated feeding, heating, and pressing, improving production efficiency. It also allows for adjustable pressure and temperature, adapting to different medical composite materials such as TPU film and medical non-woven fabric. This equipment is suitable for the production of medical dressings, protective clothing, composite films, and other products, featuring high precision and high efficiency.
