Description

Technical Field

[0001] The invention relates to the technical field of film production and molding, in particular to a melting and molding device for producing medical dry films. Background Art

[0002] Medical dry film refers to the medium used to carry medical imaging graphic information. At present, most of the films used in radiology are chemical imaging films. Common chemical imaging films include laser films and thermal films. Thermal films have the characteristics of being waterproof, tear-resistant, and resistant to high temperatures, making thermal films widely used in medical imaging such as CT examinations, magnetic resonance imaging, CR, DR, etc., and are often used as the basis for doctors' diagnosis and treatment. Medical dry film uses PET film base as a support, with silver halide emulsion coated on the front and a protective layer on the back to ensure the clarity and durability of the image. The relationship between medical dry film and thermal film is that thermal film is a type of medical dry film, and there is an inclusive relationship between the two. Thermal film is also called medical dry thermal film. It is a special type of medical dry film suitable for specific medical imaging recording needs.

[0003] When producing thermal films, the existing medical dry film melting and molding device needs to extrude and thin the thick sheet glue squeezed out by the extruder, and then guide it through the guide roller and enter the winding device to be wound into a roll. However, the film does not have a re-pressing function after being extruded by the extruder, which easily leads to uneven thickness of the film during the extrusion process, thereby reducing the quality of film molding. Summary of the invention

[0004] The object of the present invention is to provide a melting and molding device for producing medical dry film to solve the problems raised in the above-mentioned background technology.

A frame is installed on the conveying main body, and a vertical guide rail is installed on the frame. A slide seat is slidably installed on the vertical guide rail, and a linkage plate is installed on the slide seat. The linkage plate is connected to the slider through a push-pull plate. When the smelted material is extruded onto the conveying main body by the extruder, the vertical guide rail is started, so that the slide seat can drive the linkage plate to move downward along the vertical guide rail. During the downward movement, the linkage plate can push the slider to move horizontally in the slideway through the push-pull plate, thereby driving the rolling roller to evenly extrude the newly formed film on the conveying main body, thereby ensuring that the output film has a consistent thickness and improving the molding quality of the film.

[0006] As a preferred technical solution, the rolling roller is located in a conveying groove of the conveying body, and both ends of the push-pull plate are respectively hinged to the linkage plate and the slider.

[0007] As a preferred technical solution, a rolling rotation utilization component and a rolling movement utilization component are provided on the conveying body, and the operation of the rolling roller is used to provide operating driving force for the rolling rotation utilization component and the rolling movement utilization component.

[0008] As a preferred technical solution, the rolling and rotating utilization assembly includes a driving wheel, a transmission rod, a connecting plate, a vertical plate, a rotating column, a driven wheel, a transmission belt, a reciprocating screw, a moving seat, a cylinder body, a piston, a piston rod and a sliding hole; A driving wheel is installed on the rotating tube, and transmission rods are installed on the two groups of sliding blocks. The upper ends of the transmission rods are connected by connecting plates. A vertical plate is installed on the upper part of the transmission rod, and a rotating column is rotatably installed on the vertical plate. Driven wheels are installed at the opposite ends of the two groups of rotating columns. Transmission belts are sleeved on the driven wheel and the driving wheel. Reciprocating screws are installed on the opposite ends of the two groups of rotating columns, and a moving seat is slidably installed on the reciprocating screws. A cylinder body is installed on the connecting plate, and two chambers are symmetrically opened in the cylinder body, and pistons are slidably installed in the two chambers. The opposite backs of the two pistons Both are equipped with piston rods, and a sliding hole is opened on one side of the two chambers close to the piston connected to the piston rod. The piston rod passes through the sliding hole and is connected to a nearby moving seat. When the rolling roller squeezes along the film, the rolling roller can drive the driving wheel to rotate through the rotating tube during the extrusion process. Under the pulley transmission composed of the driving wheel, the driven wheel and the transmission belt, the driven wheel can drive the reciprocating screw to rotate through the rotating column, so that the moving seat on the reciprocating screw can move back and forth laterally, and then the moving seat can drive the piston to synchronously displace in the chamber of the cylinder body through the piston rod during the movement.

[0009] As a preferred technical solution, when the two reciprocating screws rotate, the two pistons are always kept moving in opposite directions to achieve alternating operation of the two chambers.

[0010] As a preferred technical solution, the rolling and rotating utilization assembly also includes a liquid suction chamber, a liquid infusion chamber, a cooling box, a liquid return pipe, a liquid suction pipe, a liquid infusion pipe, a delivery pipe, a cooling chamber, a rotating joint, a top plate and a support rod; The two chambers are formed with a liquid suction chamber and a liquid infusion chamber through pistons, a top plate is installed on the frame, the top plate is connected to the smelting body through a support rod, a cooling box is installed on the upper surface of the top plate close to the smelting body, the liquid suction chamber is connected to the cooling box through a liquid return pipe, a cooling chamber is arranged in the rolling roller, the cooling chamber is connected to the rotating tubes at both ends, a rotating joint is installed at the ends of the two rotating tubes, the liquid suction chamber is connected to one of the rotating joints through a liquid suction tube, the liquid infusion chamber is connected to the cooling box through a liquid infusion tube, and the liquid infusion chamber is connected to the other rotating joint through a delivery tube, and when the two pistons move toward each other, the liquid suction chamber in one chamber is connected to the cooling box through a liquid infusion tube. The liquid chamber and the infusion chamber can move with the movement of the piston, so that the liquid suction chamber can absorb the coolant in the cooling chamber of the rolling roller through the liquid suction tube, and the coolant in the infusion chamber can be injected into the cooling chamber through the delivery tube, which can form a replacement of the coolant in the cooling chamber, can ensure the heat dissipation effect of the rolling roller on the film, and is conducive to the rapid molding of the film. At the same time, the liquid suction chamber and the infusion chamber in the other chamber can move with the movement of the piston, so that the coolant carrying heat sucked into the liquid suction chamber can flow back into the cooling box through the return pipe, and the infusion chamber can absorb the coolant in the cooling box through the infusion tube. By utilizing the alternating operation of the two chambers, the circulation of the coolant in the cooling chamber can be realized.

[0011] As a preferred technical solution, the liquid return pipe, liquid suction pipe, liquid infusion pipe and delivery pipe are all one-way pipes.

During the rotation, the transmission ring can drive the synchronous rotation of the transmission ring teeth through the connecting rod. Through the meshing action of the transmission ring teeth and the driven teeth, the rotating shaft can drive the stirring blades to stir the coolant in the cooling box, which is beneficial to improving the cooling effect of the refrigerator on the coolant carrying heat.

[0013] Compared with the prior art, the beneficial effects achieved by the present invention are: When the smelted material is extruded onto the conveying body by the extruder, the vertical guide rail is started so that the slide can drive the linkage plate to move downward along the vertical guide rail.
