Embodiment Construction

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0041] see Figure 1-13 , an LDPE film production process that is convenient for positioning and detection is produced using LDPE film composite equipment, including the following steps:

[0042] S1, install the roll with the release film on the second positioning block 96, and pass the release film through the middle of the two second guide wheels 103, the middle of the two third guide wheels 112, and the movable turn The middle part of the roller 123 and th...

Abstract

The invention discloses an LDPE film production process that is convenient for positioning and detection. It includes a machine body, a raw material fixing groove is opened on one side of the top of the body, and the top of the body is from a side close to the raw material fixing groove to a side away from the fixing groove The first mounting frame, the second mounting frame, the third mounting frame, the fourth mounting frame, the drying box and the fifth mounting frame are fixedly connected in sequence, and the raw material fixing component is fixedly connected to the inside of the raw material fixing groove. This LDPE film production process is convenient for positioning and detection. By adding a layer of tin foil in the middle of the two layers of LDPE fluid, the products produced by this process have a strong effect of reflecting sound waves, and then when using an acoustic wave detector to detect underground pipe networks , can reflect the sound wave, not only can play the role of locating the pipe network, but also can calculate the reflection time of the sound wave, and then infer the depth of the pipe network from the ground, through the use of various devices, the production process is simple and convenient Purpose of processing.

Description

technical field [0001] The invention relates to the technical field of LDPE film processing, in particular to an LDPE film production process that is convenient for positioning and detection. Background technique [0002] Urban underground pipelines refer to pipelines and ancillary facilities for water supply, drainage, gas, heat, electricity, communications, radio and television, industry, etc. within the city, and are important infrastructure and "lifelines" to ensure urban operation. However, in the later stage of urban reconstruction or construction, the problem of digging the pipe network often occurs, which has a great impact on people's production and life. The existing devices for detecting underground pipe networks are expensive, but the detection effect is poor. In general, an auxiliary product that is convenient for detecting the pipe network in the later stage is needed to solve this problem, so a LDPE film production process that is convenient for positioning an...
