Problems solved by technology

[0003] At present, the polyester fiber screen produced by domestic manufacturers is produced by high-speed spinning process, which has poor wear resistance and fatigue resistance. Therefore, the product woven by this method has a short service life.
Using high-viscosity polyester chips for conventional spinning of polyester fibers, if not treated in the early stage, melt deformation or rupture often occurs, resulting in irregular filaments, seriously affecting the quality of fibers, and even cannot be produced normally
Secondly, after heat treatment, the polyester chip has poor uniformity and is prone to local defects in the later stage, resulting in a decrease in the overall stability of the produced screen.
Furthermore, in the existing polyester fiber screen production process, the connection between various production equipment is not tight, it takes a lot of time to transfer products, the production efficiency is not high, and a lot of manpower and material resources are required

Embodiment 1

[0027] In this example, if figure 1 and figure 2 As shown, the heating pretreatment device includes a heating and polycondensation actuator for heating and polycondensing polyester chips under the protection of nitrogen, an air supply mechanism for feeding nitrogen into the heating and polycondensation actuator, and a heating and polycondensation actuator. The vacuum degassing mechanism for vacuum degassing the final polyester chips. Through the setting of the heating and polycondensation actuator, the polyester chips are heated and polycondensed, and the heating and polycondensation is carried out under the protection of nitrogen, so as to avoid impurity reactions and affect the effect of subsequent products. The setting of the air supply mechanism facilitates the delivery of nitrogen gas to the heating polycondensation actuator to ensure the supply demand of nitrogen gas. The setting of the vacuum defoaming mechanism facilitates vacuum defoaming of the polyester chips aft...

Embodiment 2

[0037] The difference between this embodiment and embodiment 1 is that, as image 3 and Figure 4 As shown, a column 27 is arranged between the defoaming tank and the barrel, and a manipulator 28 is arranged on the column, so as to facilitate taking out the defoamed polyester material and putting it into the hopper. The manipulator can perform actions such as rising, falling, swinging and rotating, which is convenient for flexible control to grab the polyester material and then put it into the feeding hopper. In order to facilitate the manipulator to grab garbage better and more flexibly, such as Figure 4 As shown, a base 29, a rotary driver 30 arranged on the base 29, a rotatable rotating seat 31 connected to the rotating driver 30, and a rotating seat 31 arranged on the rotating seat 31 for grabbing garbage can be provided at the front end of the manipulator. Jaw 32. The base is fixedly connected with the end effector of the manipulator. There are many forms of rotary d...

Embodiment 3

[0039] The difference between this embodiment and Embodiment 1 is that the defoaming tank is provided with a feed port connected to the outlet of the feed pipe, so that the polycondensed polyester can be directly introduced into the defoaming tank.

[0040] The molding device 33 includes an integral molding mold and a pouring pipe, the feed end of the pouring pipe is connected to the discharge end of the melting conveying device, and the discharge end of the pouring pipe is connected to the feed port of the forming mold. The polyester melt is poured into the molding die, and after being shaped by the molding die, it is demolded and taken out. Forming mold is as in the prior art, does not repeat too much here.

Abstract

The invention provides a polyester fiber screen mesh production device. The device comprises a heating pretreatment device used for carrying out heating polycondensation and vacuum defoaming on polyester chips, a melting conveying device used for extruding and melting polyester materials treated by the heating pretreatment device, and a forming device used for forming molten mass conveyed by the melting conveying device. According to the device, the uniformity of polyester can be improved, local defects are avoided, and then the stability of a screen mesh produced in the later period is improved. All production devices are closely connected to form a flow production line, so that the wear resistance and the cold and hot impact resistance of the finally prepared polyester fiber screen mesh can be improved.

Description

technical field [0001] The invention relates to the technical field of screen mesh processing and production, in particular to a polyester fiber screen mesh production device. Background technique [0002] Polyester fiber screen is easy to install, easy to replace and maintain, suitable for any type of screening machine, light in weight, and can be installed or replaced on site, greatly reducing the workload. More and more fields need to use polyester screen. [0003] At present, the polyester fiber screen produced by domestic manufacturers is produced by high-speed spinning process, which has poor wear resistance and fatigue resistance. Therefore, the product woven by this method has a short service life. Using high-viscosity polyester chips for conventional spinning of polyester fibers, if not treated in the early stage, melt deformation or rupture often occurs, resulting in irregular filaments, seriously affecting the quality of fibers, and even cannot be produced normall...
