A multi-purpose colloid perfusion device

Abstract

The invention relates to an adhesive extrusion device, and in particular relates to a multi-purpose adhesive infusion device. The device comprises a pipe body, a pushing rod and a pipe tip, wherein one end of the pushing rod is provided with a piston, the other end of the pushing rod is provided with a handle, the end, provided with the piston, of the pushing rod extends into the pipe body from one end of the pipe body, and the end, provided with the handle, of the pushing rod is located outside the pipe body; the pipe tip is arranged at the end, far away from the handle, of the pipe body, and a bent adhesive outflow path is arranged in the pipe tip; a graduated cylinder is arranged inside the pipe body, one end of the graduated cylinder is connected with the adhesive outflow path, and the piston can reciprocate along the inner wall of the graduated cylinder; and a control valve for controlling clamping contraction or loosening of the pipe wall of one end, far away from the pipe tip, of the pipe body is arranged on the pipe body. By internally arranging the graduated cylinder and the control valve, the use amount of metered adhesive and adhesive infusion rate can be conveniently controlled; and the device has the characteristics of accurate infusion, simple operation, convenience and rapidness, and cost saving, and can meet the multi-purpose demands of different products in multiple fields.

Description

technical field [0001] The invention relates to a device for extruding colloid, in particular to a multipurpose colloid infusion device. Background technique [0002] In the construction, interior decoration, medical equipment, electronic appliances and other industries, the manual glue gun is a special tool in the process of gluing and sealing. The common manual glue gun consists of three parts: the operating handle, the liquid filling cylinder and the needle. Prepare and fill according to the preparation requirements of the solution before use, and place it in the sealed liquid cylinder of the glue gun. Manually push the pushing device so that the pushing device moves toward the extrusion port of the glue gun, and the sealant in the cylinder is squeezed by the glue gun. The pushing of the pushing device pushes the sealant contained in it out of the front opening so that it reaches the target position, such as a narrow gap to be glued or sealed. However, the above-mentione...

AI Technical Summary

Problems solved by technology

However, the above-mentioned manual glue gun has disadvantages: the amount of solution used each time during the filling operation cannot be accurately measured, which affects the effect of filling; the measuring cylinder and the glue head tube are for one-time use, which is easy to cause waste
