Embodiment Construction

[0040] As shown in Figure 1, the present invention discloses a kind of extruding device, and its casing 1 is provided with the space that accommodates glue stick 6, and the front end of glue stick 6 is a glue outlet 62, and the front end of glue stick 6 leans against On the front end of the housing 1 , the glue outlet 62 protrudes outside the housing 1 . A piston rod 2 extending along the piston rod axis X is movably arranged on the housing 1 of the extrusion device, and can slide relative to the housing 1. The front end of the piston rod is provided with a piston disc 21, and the piston disc 21 is connected with the rubber The rear end of the stick 6 is in contact, and the rear end of the glue stick can move relative to the glue stick 6, thereby driving the piston rod 2 by pressing the trigger 7 to squeeze the glue out from the glue outlet 62.

[0041] As shown in FIG. 2 , a U-shaped driving member 3 is slidably fitted with the piston rod 2 . The driving member 3 is an elast...

Abstract

The invention relates to a glue extruding device which comprises a casing used for supporting a glue rod, a piston rod used for extruding glue, a U-shaped driving piece matched with the piston rod in a sliding manner, and a cam which rotates around Y axis, wherein, the circumference of the cam is the cam surface; two end parts of the driving piece are respectively a driving part and a locking part; and the cam can transfer the energy to the driving piece and the piston rod through the cam surface when rotating, so that the glue is extruded. Compared with the prior art, the invention has the beneficial effects that the structure of the glue extruding device is simple, the manufacture and the assembly of parts are simple, and the whole glue extruding device is small in volume and light in weight.

Description

technical field [0001] The invention relates to a rubber extruding device. Background technique [0002] US Patent No. 7,063,240 discloses a rubber extruding device. Inside the device are two cams that drive the drive rod and the piston rod. But the cam faces of these two cams are located on the axial face of the cam, which causes the processing of the cam to be more complicated, and the placement of the cams before and after makes the volume of the whole extruding device increase, the weight increases, and the operation is inconvenient. [0003] U.S. Patent No. 4,264,021 and Japanese Patent JP2005145564 also disclose a rubber extruding device. The cam surface of the cam is arranged on the circumferential surface of the cam, which reduces the volume of the extruding device. However, due to the large number of parts, the assembly is more complicated. Contents of the invention [0004] The object of the present invention is to provide a stable and reliable extrusion dev...
