Embodiment 1

[0049] Such as figure 1 with figure 2 As shown, a system for extruding collagen in this embodiment includes a displacement sensor, a single-chip microcomputer, a motor 200, and an extrusion device 300. The motor 200 is provided with a vertically arranged push rod 201, and the push rod The upper end of 201 is connected with the bottom of the extruding device, and the motor 200 drives the push rod 201 to move vertically upwards to extrude the collagen in the extruding device 300 into a mould; the displacement sensor and the The motors 200 are all connected with the single-chip microcomputer through a circuit;

[0050] The single-chip microcomputer is used to control the displacement sensor to detect the displacement value of the upward movement of the push rod 201 and control the operation mode of the motor 200 according to the displacement value, thereby controlling the extrusion thickness of the mold in the extrusion device 300 .

[0051] In the system of this embodiment, ...

Embodiment 2

[0073] Such as Figure 3-Figure 7 As shown, a device for extruding collagen in this embodiment includes a frame 100 and the above-mentioned system, and the motor 200 and the extruding device 300 are installed in the frame 100; the extruding device 300 includes an extruding cylinder assembly and an extruding cylinder cover 309, and several drainage holes are opened on the extruding cylinder assembly and the extruding cylinder cover 309; the extruding cylinder cover 309 is arranged horizontally and its upper side Connected to the inner surface of the top of the frame 100 , an extrusion chamber with an open upper end is formed in the extrusion cylinder assembly, and the extrusion cylinder head 309 is arranged vertically opposite to the open end of the extrusion chamber. The device of the invention has a simple structure and can fully and effectively squeeze the collagen in the extrusion chamber.

[0074] Such as Figure 3-Figure 7 As shown, the extrusion cylinder assembly in th...

Abstract

The invention relates to a system and a device for collagen extrusion molding. The system comprises a displacement sensor, a single chip microcomputer, a motor and an extrusion device, wherein a pushing rod which is vertically arranged is arranged on the motor; the upper end of the pushing rod is connected with the bottom of the extrusion device; the motor drives the pushing rod to vertically moveupwards for extruding collagen in the extrusion device into a mould; both the displacement sensor and the motor are connected with the single chip microcomputer through circuits; and the single chipmicrocomputer is used for controlling the displacement sensor to detect an upwards movement displacement value of the pushing rod and controlling an operation mode of the motor according to the displacement value, so that extrusion thickness of the mould is controlled. According to the system disclosed by the invention, the thickness of the finally molded collagen mould is controlled by the size of displacement acquired by the displacement sensor, so that manual operation is cancelled, control on the thickness of the collagen mould is more precise, and the yield is high.

Description

technical field [0001] The invention relates to the technical field of collagen molds, in particular to a system and device for extruding collagen. Background technique [0002] At present, market products need a collagen thin sheet with a certain thickness to squeeze out moisture, so as to be used for making dura mater. There is no ready-made equipment on the market that can be used to make this collagen sheet. Although it can be pressed manually, the manual pressing method is labor-intensive and the thickness is not completely consistent. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a system and device for extruding collagen in view of the deficiencies in the prior art. [0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a system for extruding collagen, including a displacement sensor, a single-chip microcomputer, a motor and an extrusion d...
