Description

Technical Field

[0001] The present invention relates to the technical field of film production and forming, and specifically relates to a melting and forming device for medical dry film production. Background Art

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

[0003] When the existing melting and forming device for medical dry film produces thermal film, it is necessary to extrude and thin the thick sheet glue extruded by the extruder, and then guide it through a guide roller and enter the winding device to be wound into a roll. However, the film does not have a repressing function after being extruded by the extruder, which easily causes the thickness of the film to be uneven during the extrusion process, thereby reducing the forming quality of the film. Summary of the Invention

[0004] The purpose of the present invention is to provide a melting and forming device for medical dry film production to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention provides the following technical solution: A melting and forming device for medical dry film production, the melting and forming device for medical dry film production includes a melting main body, an extruder, and a conveying main body.

On the sliders, rotating tubes are rotatably installed. The rotating tubes are connected by rolling rollers. A frame is installed on the conveying main body. On the frame, a vertical guide rail is installed. A sliding seat is slidably installed on the vertical guide rail. A linkage plate is installed on the sliding seat. The linkage plate is connected to the slider through a push-pull plate. When the material after melting is extruded by the extruder onto the conveying main body, the vertical guide rail is started, so that the sliding seat can drive the linkage plate to move downward along the vertical guide rail. During the downward movement of the linkage plate, it can push the slider to move horizontally in the slideway through the push-pull plate, thereby being able to drive the rolling rollers to uniformly extrude the just-formed film on the conveying main body, and further being able to ensure that the thickness of the output film is consistent and improve the forming quality of the film.

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

When the rolling roller extrudes along the film, the rolling roller can drive the driving wheel to rotate through the rotating pipe during the extrusion process. Under the belt drive composed of the driving wheel, the driven wheel and the transmission belt, the driven wheel can drive the reciprocating lead screw to rotate through the rotating column, so that the moving seat on the reciprocating lead screw moves horizontally back and forth, and further enables the moving seat to drive the piston to perform synchronous displacement in the chamber of the cylinder body through the piston rod during the movement.

[0010] As a preferred technical solution, when the two reciprocating lead screws rotate, the two pistons always move in opposite directions to realize the alternating operation of the two chambers.

[0011] As a preferred technical solution, the rolling rotation utilization assembly further 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 rotary joint, a top plate and a support rod;

[0012] Both of the two chambers form a liquid suction chamber and a liquid infusion chamber through pistons. A top plate is installed on the frame, and the top plate is connected to the smelting main body through a support rod. A cooling box is installed on one side of the upper surface of the top plate close to the smelting main body. The liquid suction chamber is connected to the cooling box through a liquid return pipe. A cooling cavity is arranged inside the rolling roller, and the cooling cavity is communicated with the rotating pipes at both ends. Rotating joints are installed at the ends of the two rotating pipes. The liquid suction chamber is connected to one of the rotating joints through a liquid suction pipe. The liquid infusion chamber is connected to the cooling box through a liquid infusion pipe. The liquid infusion chamber is connected to the other rotating joint through a delivery pipe.

Under the belt drive composed of the driving wheel 1301, the driven wheels 1306 and the transmission belt 1307, the driven wheels 1306 can drive the reciprocating lead screw 1308 to rotate through the rotating columns 1305, so that the moving seat 1309 on the reciprocating lead screw 1308 makes a transverse reciprocating movement, and further enables the moving seat 1309 to drive the piston 1311 to make a synchronous displacement in the chamber of the cylinder block 1310 through the piston rod 1312 during the movement.

[0038] When the two reciprocating lead screws 1308 rotate, the two pistons 1311 always move in opposite directions, realizing the alternating operation of the two chambers.

The top plate 1323 is connected to the smelting main body 1 through a support rod 1324. A cooling box 1316 is installed on one side of the upper surface of the top plate 1323 close to the smelting main body 1.

When the two pistons 1311 move towards each other, the liquid suction chamber 1314 and the liquid infusion chamber 1315 in one chamber can move along with the movement of the piston 1311, so that the liquid suction chamber 1314 can suck the coolant in the cooling chamber 1321 of the rolling roller 7 through the liquid suction pipe 1318, and the coolant in the liquid infusion chamber 1315 can be injected into the cooling chamber 1321 through the delivery pipe 1320, so as to form the replacement of the coolant in the cooling chamber 1321, which can ensure the heat dissipation effect of the rolling roller 7 on the film and is beneficial to the rapid forming of the film. At the same time, the liquid suction chamber 1314 and the liquid infusion chamber 1315 in the other chamber can move along with the movement of the piston 1311, so that the coolant carrying heat sucked into the liquid suction chamber 1314 can flow back to the cooling box 1316 through the liquid return pipe 1317, and the liquid infusion chamber 1315 can suck the coolant in the cooling box 1316 through the liquid infusion pipe 1319.

[0043] A fixed block 1401 is installed on the cylinder block 1310. A transmission shaft 1402 is installed on the fixed block 1401. A spiral track 1403 is provided on the transmission shaft 1402. A fixed ring 1404 is fixedly installed on the cooling tank 1316. A transmission ring 1405 is rotatably installed on the fixed ring 1404. A driving rod 1406 is rotatably installed on the inner diameter of the transmission ring 1405. The driving rod 1406 is inserted into the spiral track 1403. A connecting rod 1407 is installed on the transmission ring 1405. A transmission ring gear 1408 is installed on the connecting rod 1407.

When the rolling roller 7 moves along the film, the rolling roller 7 drives the transmission shaft 1402 to move synchronously through the cylinder block 1310. By using the sliding fit between the spiral track 1403 and the driving rod 1406, the transmission shaft 1402 can drive the transmission ring 1405 to rotate through the extrusion of the driving rod 1406 by the spiral track 1403 during the movement. During the rotation of the transmission ring 1405, the transmission ring 1405 can drive the synchronous rotation of the transmission ring gear 1408 through the connecting rod 1407. Through the meshing action between the transmission ring gear 1408 and the driven gear 1411, the rotating shaft 1409 can drive the stirring blade 1410 to stir the coolant in the cooling tank 1316, which is beneficial to improving the refrigeration effect of the refrigerator 1412 on the coolant carrying heat.

[0044] Working principle of the present invention:

[0045] When the material after smelting is extruded by the extruder 2 onto the conveying main body 3, the vertical guide rail 9 is started, so that the sliding seat 10 can drive the linkage plate 11 to move downward along the vertical guide rail 9. During the downward movement of the linkage plate 11, the sliding block 5 can be pushed by the push-pull plate 12 to move horizontally in the slideway 4, thereby driving the rolling roller 7 to uniformly extrude the just-formed film on the conveying main body 3, and further ensuring that the thickness of the output film is consistent and improving the forming quality of the film.

[0046] When the rolling roller 7 extrudes along the film, the rolling roller 7 can drive the driving wheel 1301 to rotate through the rotating tube 6 during the extrusion process. Under the belt drive composed of the driving wheel 1301, the driven wheel 1306 and the transmission belt 1307, the driven wheel 1306 can drive the reciprocating lead screw 1308 to rotate through the rotating column 1305, so that the moving seat 1309 on the reciprocating lead screw 1308 moves horizontally back and forth, and further enables the moving seat 1309 to drive the piston 1311 to move synchronously in the chamber of the cylinder block 1310 through the piston rod 1312 during the movement.

[0047] When the two pistons 1311 move towards each other, the liquid suction chamber 1314 and the liquid delivery chamber 1315 in one chamber can move along with the movement of the piston 1311, enabling the liquid suction chamber 1314 to suck the coolant in the cooling chamber 1321 of the rolling roller 7 through the liquid suction pipe 1318, and enabling the coolant in the liquid delivery chamber 1315 to be injected into the cooling chamber 1321 through the delivery pipe 1320, so as to form the replacement of the coolant in the cooling chamber 1321, which can ensure the heat dissipation effect of the rolling roller 7 on the film and is beneficial to the rapid forming of the film. At the same time, the liquid suction chamber 1314 and the liquid delivery chamber 1315 in the other chamber can move along with the movement of the piston 1311, enabling the coolant carrying heat sucked into the liquid suction chamber 1314 to flow back to the cooling tank 1316 through the liquid return pipe 1317, and enabling the liquid delivery chamber 1315 to suck the coolant in the cooling tank 1316 through the liquid delivery pipe 1319. By means of the alternating operation of the two chambers, the circulating flow of the coolant in the cooling chamber 1321 can be realized.

[0048] When the rolling roller 7 moves along the film, the rolling roller 7 drives the transmission shaft 1402 to move synchronously through the cylinder block 1310. By means of the sliding fit between the spiral track 1403 and the driving rod 1406, the transmission shaft 1402 can drive the transmission ring 1405 to rotate by squeezing the driving rod 1406 through the spiral track 1403 during the movement. During the rotation of the transmission ring 1405, the transmission ring 1405 can drive the synchronous rotation of the transmission ring gear 1408 through the connecting rod 1407. Through the meshing action between the transmission ring gear 1408 and the driven gear 1411, the rotating shaft 1409 can drive the stirring blade 1410 to stir the coolant in the cooling tank 1316, which is beneficial to improving the refrigeration effect of the refrigerator 1412 on the coolant carrying heat.
