Description

Technical Field

[0001] The utility model relates to the technical field of aseptic pipe connection, in particular to a pressing mechanism of an aseptic pipe connecting machine. Background Art

[0002] An aseptic pipe connecting machine is a special device that can cut and connect aseptic hoses, and is widely used in blood collection and supply, dialysis, surgery, and pharmaceutical manufacturing. When an aseptic pipe connecting machine is in use, a cutting knife is required to cut and heat the pipe to be connected, and then the cut ends to be connected are moved and butted and fused together.

[0003] For example, a Chinese utility model patent with the authorization announcement number CN220052943U and the patent name of an aseptic pipe connecting machine capable of adapting to pipe diameter and wall thickness includes: a frame; two clamping assemblies arranged oppositely, each clamping assembly includes a supporting part for supporting the pipe, and three clamping blocks arranged at intervals on the upper side of the supporting part. A clamping space for clamping the pipe is formed between two adjacent clamping blocks; wherein, the clamping blocks of the two clamping assemblies are arranged such that the pipe can extend into the clamping spaces of the two clamping assemblies at the same time. Among the three clamping blocks, one of the clamping blocks at the edge is set as a fixed clamping block, and the other two clamping blocks are set as movable clamping blocks. The clamping assembly further includes a driving part, and the movable clamping block at the edge is connected to the driving part; one clamping assembly can move in a first direction, and one clamping assembly can move in a second direction. The first direction is consistent with the axis direction of the clamping space, and the second direction is perpendicular to the first direction.

[0004] During the process of fusing and connecting the two cut ends to be connected in the above-mentioned comparative document, after the cutting knife completes cutting and heating, the cutting knife needs to move upward to the upper part of the cut end to be connected. In order to prevent the just-heated material from being adhered away during the upward movement of the cutting knife, before the cutting knife moves upward, the clamping assembly that can move in the first direction needs to move one of the cut ends to be connected in the first direction and away from the cutting knife by a small distance, so that there is a small distance between the two cut ends to be connected first, and then the cutting knife moves upward, which can prevent the heated material from being adhered away during the upward movement of the cutting knife. However, since the other clamping assembly cannot move in the first direction, the cut end to be connected clamped by it cannot move in the first direction either, resulting in the cutting knife always being in contact with the cut end to be connected during the upward movement of the cutting knife, and the cutting knife will continue to heat it, so that when the next fusion connection is carried out, the cross-sectional temperatures of the two cut ends to be connected are different, and the different cross-sectional temperatures will directly affect the fusion connection effect and reduce the connection strength at the fusion connection. Summary of the Utility Model

[0030] In the technical solution proposed in the present application, the fixed clamping member 214 and the movable clamping member 213 of one clamping unit 21 cooperate to clamp one pipe to be connected, and the fixed clamping member 214 and the movable clamping member 213 of the other clamping unit 21 cooperate to clamp the other pipe to be connected. The first driving member 12 drives the two second mounting plates 16 to approach each other until the end faces of the two pipes to be connected are aligned. The cutting knife passes through between the two pipes to be connected to heat the end faces of the two pipes to be connected. After the heating is completed, the cutting knife first remains stationary, and the first driving member 12 drives the two second mounting plates 16 to move away until the end faces of the two pipes to be connected are separated from the cutting knife respectively. At this time, the cutting knife moves upward until the cutting knife moves above the pipes to be connected, and the first driving member 12 drives the two second mounting plates 16 to approach each other to perform fusion connection on the end faces of the two pipes to be connected. At this time, the temperatures of the end faces of the two pipes to be connected are the same, and the fusion connection effect is better.

It is common general knowledge in the art that the DC motor can drive the driving rod 14 to rotate, and thus the structure and specific working principle thereof will not be elaborated herein.
