Problems solved by technology

The current thermoforming method is mainly to heat one end of the heat-shrinkable double-walled tube one by one manually or by machine. Manual operation will lead to inconsistent appearance of the product and affect the appearance, and this method of heating and forming the ends one by one is extremely inefficient. , is not conducive to the realization of automated production

Embodiment Construction

[0027] In order to make the object, technical solution and beneficial technical effects of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific implementations described in this specification are only for explaining the present invention, not for limiting the present invention.

[0028] see Figure 1 to Figure 3 , the embodiment of the present invention provides a capping tube forming method, the method specifically includes the following steps:

[0029] In the heating step, at least one heat-shrinkable double-walled tube 50 is taken, and the non-end position of the heat-shrinkable double-walled tube 50 is heated, the outer layer of the heat-shrinkable double-walled tube 50 shrinks and the inner layer of the hot melt adhesive layer 52 are melt-bonded together to form a closed section;

[0030] In the cutting step, the clo...

Abstract

The invention discloses a cap sealing pipe forming method which comprises the following steps: a heating step: taking at least one thermal shrinkage double-wall pipe, heating the non-end position of the thermal shrinkage double-wall pipe, shrinking the outer layer of the thermal shrinkage double-wall pipe at the heated position, and melting and bonding hot melt adhesive layers of the inner layer together to form a closed section; and a cutting step: the closed section of the thermal shrinkage double-wall pipe is cut off, so that the thermal shrinkage double-wall pipe is processed and formed into two cap sealing pipe products, one end of each cap sealing pipe is opened, and the other end of each cap sealing pipe is closed. The invention further discloses an automatic forming device for the cap sealing pipe. The non-end position of the thermal shrinkage double-wall pipe is heated to be shrunk and then cut, one thermal shrinkage double-wall pipe can be formed into two cap sealing pipe products at the same time, the appearance consistency is high, and the production efficiency is greatly improved.

Description

【Technical field】 [0001] The invention relates to the technical field of mechanical equipment, in particular to an automatic forming device and a forming method for a sealing cap tube. 【Background technique】 [0002] During the production and processing of the capped tube, the end of the heat-shrinkable double-walled tube is generally heated, and the hot-melt adhesive layer on the inner wall melts during heating, and shrinks with the outer wall to form a capped tube. The current thermoforming method mainly heats one end of the heat-shrinkable double-walled tube one by one manually or by machine. Manual operation will lead to inconsistent appearance of the product and affect the appearance, and this method of heating and forming the ends one by one is extremely inefficient. , is not conducive to the realization of automated production. In view of this, it is necessary to provide an automatic forming device and forming method for capped tubes to overcome the above-mentioned d...
