Abstract

The invention discloses a heat-sheet membrane sealing machine and a membrane sealing process of a dialyser. The heat-sheet membrane sealing machine is provided with a frame body, a clamping device, calibration devices, a mobile device, a drive device, a heat-sealing device and a control device, wherein the clamping device is fixed on the mobile device; the mobile device is connected with the drive device; the calibration devices are arranged at the two sides of the clamping device; the mobile device is provided with a fixed frame and a mobile frame; the clamping device is designed to be a U-shaped support; the calibration device is provided with a calibration plate and a calibration air cylinder; and the heat-sealing device is provided with a heat-sealing frame and a strip-shaped heat sheet. The membrane sealing process of the dialyser comprises the following steps of: placing the dialyser on the clamping device; adjusting the end part of the dialyser by the calibration device; driving the mobile device to move by the drive device and transporting the dialyser to the heat-sealing device; driving the mobile device to move by the drive device so that the dialyser gradually passes through the heat-sealing device; and returning to an initial position. The membrane-sealed product has the advantages of stable quality and high automation degree, and is suitable for batch production.

Description

technical field [0001] The invention relates to the field of dialyzer manufacturing machinery and equipment, in particular to a hot plate film sealing machine and a film sealing process for sealing a fiber membrane of a dialyzer. Background technique [0002] Dialyzer, commonly known as artificial kidney, has been widely used clinically. By performing hemodialysis, the patient's life can be appropriately extended. A dialyzer usually includes a housing, a hollow fiber arranged in the housing, a blood inlet pipe, a blood outlet pipe, a dialysate outlet pipe and a dialysate inlet pipe arranged at both ends of the housing. During the manufacturing process of the dialyzer, it is necessary to put the fiber membrane into the shell, then cut the two ends of the fiber membrane, and realize the plugging at the same time through the cutting process. [0003] The film sealing process in the prior art uses a hot wire to cut the sealing film, fix the dialyzer on the fixture by hand, per...
