Problems solved by technology

[0003] The main material of the reinforced strip in the production process is a mixture of polyethylene resin and polyester fiber. The mixing of the two needs to be carried out under heating conditions, while the strip roller used in the prior art is used for extrusion coating At the same time, because the heating increases the molecular force between the mixture and the strip roller, the melting index of the polyethylene resin rises, so that the polyethylene resin and a small amount of polyester fiber cover the strip roller and are not easily taken out.

Embodiment 1

[0027] Such as figure 1 , figure 2 , Figure 4 , Figure 5 As shown, the present invention provides a kind of production equipment of polyester fiber reinforced strip, and its structure comprises cabinet 1, extrusion port 2, coating port 3, extrusion cavity 4, mixing cylinder 5, polyethylene adding port 6, deceleration 7, polyester fiber adding port 8, the chassis 1 controls the reducer 7, the signal output end of the reducer 7 is electrically connected to the extrusion chamber 5, and the inside of the extrusion chamber 5 is provided with an extrusion Screw 41, the extrusion chamber 5 is provided with a polyethylene addition port 6 and a polyester fiber addition port 8, the mixing cylinder 5 is horizontally connected to the inside of the extrusion chamber 4, and the extrusion chamber 4 is opposite to the mixing cylinder 5 Extrusion port 2 and coating port 3 are installed at one end of the tube, and strip roll 31 is arranged in the coating port 3. , the roller surface 311 ...

Embodiment 2

[0029] Based on the description in Example 1, as image 3 and Figure 6 As shown, the fitting disk 312 is an arc shape attached to the roller surface 311, and both sides are slope tangent structures. The gap between the roller surface 311 and the liquid outlet 12a is provided with a fine hole a, and the fine hole a There are more than two and are evenly distributed in the circumferential direction. The liquid collection tank 313 is divided into two equal parts, and each cut is in a Z shape. The roller surface 311 is a stepped double-layer structure. The contact between the layers is inclined to increase the oil outflow rate in the pores a, the sump 313 is divided into two equal parts, and the zigzag cut can well distribute the lubricant evenly to each outlet channel; At the same time, the roll surface 311 is double-layered, with inclined surfaces between the layers, so that the pores a have a more comprehensive liquid discharge, and the lubrication efficiency of the roll surf...

Abstract

The invention discloses production equipment of a polyester fiber reinforced strip. The production equipment structurally comprises a case, an extrusion port, a coating port, an extrusion cavity, a mixing cylinder, a polyethylene adding port, a speed reducer, a polyester fiber adding port and a case control speed reducer. A signal output end of the speed reducer is electrically connected with theextrusion cavity, an extrusion screw rod is arranged in the extrusion cavity, the extrusion cavity is provided with the polyethylene adding port and the polyester fiber adding port, the mixing cylinder is in horizontal communication with the interior of the extrusion cavity, and the end, opposite to the mixing cylinder, of the extrusion cavity is provided with the extrusion port and the coating port. A liquid collecting groove is matched with a roller core and an infusion system, the roller core rotates to open a closing disc and a closing rod by utilizing centrifugal force, a top block and aconnecting rod are hollow, and lubricant is infused from the inside of the top into the connecting rod to be diffused to the whole roller surface in a fine hole so as to play a role of lubricating theroller surface, the contact smoothness between the polyethylene and polyester fiber mixture and a strip roller is improved, the mixture coverage is reduced, and better extrusion is realized.

Description

technical field [0001] The invention relates to the technical field of polyester fiber processing, in particular to a production equipment for polyester fiber reinforced strips. Background technique [0002] Polyester fiber, commonly known as "polyester", is a synthetic fiber obtained by spinning polyester obtained by polycondensation of organic dibasic acid and dibasic alcohol, referred to as PET fiber, which belongs to polymer compounds. Reinforcing strips play a vital role in retaining walls, slope protection, high fill, tailings dams, and embankments; [0003] The main material of the reinforced strip in the production process is a mixture of polyethylene resin and polyester fiber. The mixing of the two needs to be carried out under heating conditions, while the strip roller used in the prior art is used for extrusion coating At this time, because the heating increases the molecular force between the mixture and the strip roller, the melting index of the polyethylene re...
