Problems solved by technology

[0002] Using a straw to absorb beverages has become a living habit of consumers. In order to facilitate the absorption, it is usually necessary to bend the straw. Now there are many straws in the technology. Figure 10 The structure shown in includes three parts: the first straight pipe part 101, the second straight pipe part 102 and the bellows-shaped part 103. Due to the existence of the bellows-shaped part, the suction pipe can be bent at will. It consists of a straight pipe The straw is heated and shrunk by a bending machine to form a bellows-shaped part, but the production and molding equipment of the bellows-shaped part of the straw is relatively expensive, and the cost of the straw is high

Embodiment Construction

[0030] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] combine figure 1 , figure 2 As shown, the straw 1 manufactured by the straw bending and forming mechanism of this embodiment is made into a main rib 11 composed of a plurality of triangular prismatic bodies 10 by pressure at the inner corner of the bend, and the main rib is divided into several sections. There is a concave line 12 between each section. When the straw angle becomes smaller and folded inward, the raised prismatic body shrinks and narrows, and the concave line is inwardly folded and contracted between the prismatic bodies, thereby obtaining figure 2 closed straw.

[0032] When the straw is expanded at a larger angle, the raised prismatic shape expands outward, and the concave line moves outward in the radial direction of the tube, so that the closed straw opens and the internal space of the ...

Abstract

The invention relates to a molding mechanism for bending of a suction tube, wherein the molding mechanism for the bending of the suction tube is used on a suction tube packing machine. The molding mechanism for the bending of the suction tube comprises a chain, a hook mold, a check block and an unhooking block, wherein the chain rotates driven by a chain driving component which is installed on a machine frame, the hook mold comprises a main hook and a pressing hook, the main hook and the pressing hook are connected on the chain in a chaining mode, the hook mold is provided with a concave part which is used for containing a suction tube, a groove is arranged in the inner side of the concave part, a hole in the pressing hook is connected with the chain in the axial direction and is capable of rotating, the pressing hook slides on a track, the track is fixed on the machine frame, the check block is fixed on the machine frame through an adjustable block component, the adjustable block component is used for fixing the check block and adjusting position of the check block, and the unhooking block is fixed on the machine frame at the tail end of the track. The molding mechanism for the bending of the suction tube has the advantages that the structure is simple, a heating process and a contracting process are not needed when the bending position of the suction tube is machined, and cost for manufacturing and machining of the suction tube is reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of straw packaging machine equipment, in particular to a straw bending and forming mechanism of a straw packaging machine. 【Background technique】 [0002] Using a straw to absorb beverages has become a living habit of consumers. In order to facilitate the absorption, it is usually necessary to bend the straw. Now there are many straws in the technology. Figure 10 The structure shown in includes three parts: the first straight pipe part 101, the second straight pipe part 102 and the bellows-shaped part 103. Due to the existence of the bellows-shaped part, the suction pipe can be bent at will. It consists of a straight pipe The suction pipe of the present invention forms a bellows-shaped part under heating and shrinkage through a bending machine, but the manufacturing and molding equipment of the bellows-shaped part of this suction pipe is relatively expensive, and the cost of the straw is high. 【Content o...
