Description

Technical Field

[0001] The invention relates to the technical field of double-cavity hose molding, in particular to double-cavity hose molding equipment with a tail sealing function. Background Art

[0002] ‌Double-lumen hose‌ is a hose with two independent chambers. The two chambers are not connected and work independently. The design of this hose allows two different substances to be processed or transported at the same time without mixing. The two chambers of the double-lumen hose remain independent through a special sealing design, ensuring that the substances will not leak or mix. At the same time, its softness allows it to be used in situations that require flexible movement. Double-lumen hoses are usually used in application scenarios that require separation of two different liquids or gases, such as medical, industrial, and laboratory fields.

[0037] The cooling positioning assembly 13 also includes an extrusion plate 1308, a fixing plate 1309, a driving airbag 1310, a slideway 1311, a slider 1312, a supporting spring 1313, a connecting plate 1314, a driven airbag 1315, a one-way air pipe 1316, a linkage rod 1317, and an upper cooling seat 1318;

[0038] Extrusion plates 1308 are installed at both ends of the linkage plate 1305, and fixing plates 1309 are installed on the two first electric telescopic rods 1304. The extrusion plates 1308 and the fixing plates 1309 on the same side are connected through a driving airbag 1310. Two groups of slideways 1311 are symmetrically opened on the fixed U frame 1301.

At this time, the transverse guide rail 7 is started, so that the hosting seat 8 can transport the double-lumen hose. At the same time, the module guide rail 9 is started, so that the movable seat 10 can drive the tail sealing plate 12 to move through the connecting rod 11. The two tail sealing plates 12 squeeze the double-lumen hose during the process of moving toward each other, so that the double-lumen hose on the hosting seat 8 can be automatically sealed.

[0046] When the hosting seat 8 moves along the transverse guide rail 7 to the lower cooling seat 1303, the hosting seat 8 is docked with the lower cooling seat 1303. At the same time, by starting the second electric telescopic rod 1306, the second electric telescopic rod 1306 drives the push plate 1307 to align with the pipe groove of the hosting seat 8, and then by starting the first electric telescopic rod 1304, the first electric telescopic rod 1304 can drive the linkage plate 1305 to move toward the lower cooling seat 1303, so that the push plate 1307 can push the double-chamber hose on the hosting seat 8 to the lower cooling seat 1303, so that the hosting seat 8 can be quickly reset for re-consignment.

Under the expansion effect, the driven airbag 1315 pushes the slider 1312 in the slideway 1311 to compress the support spring 1313 to move downward, so that the slider 1312 can drive the upper cooling seat 1318 to move downward synchronously through the linkage rod 1317, thereby realizing the upper cooling seat 1318 The linkage plate 1305 is docked and positioned with the lower cooling seat 1303. When the linkage plate 1305 moves toward the extruder 1 for resetting, the linkage plate 1305 can stretch the driving airbag 1310 during the movement, so that the driving airbag 1310 can inhale external airflow through the intake valve. When the linkage plate 1305 moves to the initial position, the signal detector can control the exhaust valve to open through the sensor's signal feedback to the position detector, so that the slider 1312 can move up and reset under the elastic force of the support spring 1313, which is conducive to the resetting of the upper cooling seat 1318.

[0048] When the linkage plate 1305 moves, the linkage plate 1305 can move synchronously through the tooth plate 1411 during the movement. Through the meshing action of the tooth plate 1411 and the driving gear 1410, the driving gear 1410 can drive the turntable 1412 to rotate through the rotating shaft 1409. During the rotation of the turntable 1412, the second transmission shaft 1413 can be driven to move in a circular trajectory, so that the second transmission shaft 1413 can drive the connecting block 1407 to move back and forth horizontally through the push-pull plate 1414 and the first transmission shaft 1408. When the connecting block 1407 moves horizontally, the connecting block 1407 can drive the piston 1402 to move synchronously in the cylinder body 1401 through the sliding rod 1405, so that the injection chamber 1403 can be sucked into the storage tank 141 through the first infusion tube. 7, and the return liquid chamber 1404 returns the coolant carrying heat to the liquid storage tank 1417 through the second return liquid pipe, so that the refrigerator can cool the coolant carrying heat. When the connecting block 1407 is reset, the connecting block 1407 can drive the piston 1402 to reset synchronously, so that the coolant in the injection chamber 1403 is transported to the lower cooling cavity 1319 and the upper cooling cavity 1320 through the second liquid infusion pipe, and the return liquid chamber 1404 sucks the coolant carrying heat in the lower cooling cavity 1319 and the upper cooling cavity 1320 through the first return liquid pipe, so as to realize the circulation of the coolant in the lower cooling cavity 1319 and the upper cooling cavity 1320, thereby improving the cooling effect of the lower cooling seat 1303 and the upper cooling seat 1318 on the double-lumen hose.
