Embodiment Construction

[0013] Such as Figures 1 to 3 Shown, a kind of extruder of the present invention comprises the upper pressure roller 1 that is arranged on the toothpaste bag upper bag surface and the lower pressure roller 2 that is arranged on the toothpaste bag lower bag surface, and described upper pressure roller 1 and lower pressure roller 2 pass through The two U-shaped connecting rods 3 arranged at their two ends are connected. The specific connection method is: each of the U-shaped connecting rods 3 has an upper end and a lower end, and the upper end is connected to the end of the upper pressure roller 1 through the bearing 6. The lower end is rotationally connected with the end of the lower pressure roller 1 through the bearing 6, and the middle part of the U-shaped connecting rod 3 (that is, the "U" bottom of the U-shaped connecting rod) is connected to the outlet end of the toothpaste bag. Bending; the gap between the upper and lower pressure rollers 1, 2 is equal to the sum of the...

Abstract

The invention discloses a squeezer, comprising an upper pressing roller arranged on the upper tube surface of a toothpaste tube and a lower pressing roller arranged on the lower tube surface of the toothpaste tube. The upper pressing roller and the lower pressing roller are connected by two U-shaped connecting rods which are arranged at two ends of the upper pressing roller and the lower pressing roller. Two ends of each U-shaped connecting rod are pivotally connected with the corresponding end parts of the upper pressing roller and the lower pressing roller respectively. A gap between the upper pressing roller and the lower pressing roller is equal to the sum of the thicknesses of the upper tube surface and the lower tube surface of the toothpaste tube. Both the lengths of the upper pressing roller and the lower pressing roller are equal to the width of the flattened toothpaste tube. Arc crinkles are respectively arranged at both ends of the toothpaste tube and squeezed by the upper pressing roller and the lower pressing roller to form a plurality of arc recesses. And the arc recesses are matched with the middle parts of the U-shaped connecting rods in a clamping way. According to the invention, the squeezed quantity of the toothpaste can be controlled precisely. Since the squeezed arc crinkles form the arc recesses matched with the middle parts of the U-shaped connecting rods in the clamping way, the upper pressing roller and the lower pressing roller are prevented from backing and the situation that the toothpaste is only squeezed to a toothpaste outlet end and does not flow back is guaranteed.

Description

technical field [0001] The invention relates to a toothpaste extruding device, in particular to an extruder for extruding toothpaste. Background technique [0002] Toothpaste is a product commonly used in life. Toothpaste is filled in a toothpaste bag. When brushing teeth, the toothpaste is squeezed out from the toothpaste bag with your fingers. Existing toothpaste bags are basically made of thin-walled plastic tubes. One end of the thin-walled plastic tubes is provided with a toothpaste outlet with a screw cap, and the other end is compressed and sealed. The defect that the toothpaste bag of this structure exists is: when squeezing toothpaste, the one, the extruding amount of toothpaste is difficult to control, and the 2nd, when squeezing toothpaste, the toothpaste in the toothpaste bag can flow toward the toothpaste outlet end and the flattened sealing end simultaneously. Contents of the invention [0003] The object of the present invention is to provide an extruder fo...
