Problems solved by technology

[0004] The plastic chain of the mud scraper is mainly assembled from four parts: chain plate, pin shaft, circlip and sleeve, and the chain plate is mainly a plastic plate made of POM (polyoxymethylene), which will be damaged during long-term soaking in sewage. The chain plate breaks, and after a period of overall use, there will be elongation and plastic deformation

Embodiment 1

[0064] Example 1: A production process of a plastic chain for a mud scraper. The plastic chain is composed of a plurality of chain links connected in series. The structure and size of the chain plate 1 and the inner chain plate 2 are the same, the inner sides of the two inner chain plates 2 are integrally injection molded by the sleeve 4, and the two ends of the two outer chain plates 1 are attached to the two inner chain plates 2 respectively. On the outer sides of the two ends, the outer link plate 1 and the inner link plate 2 are connected through the pin shaft 3 inserted into the sleeve 4, the pin shaft 3 is rotated in the sleeve 4, and the circlip 5 is located at both ends of the pin shaft 3 and snapped into the sleeve 4.

[0065] The outer surface of the outer link plate 1 is integrally injection-molded with reinforcing ribs 6 along its length direction, and the position where the reinforcing ribs 6 contact with the outer link plate 1 is set in a hollow shape, so as to g...

[0101] Embodiment 2: A production process of plastic chains for mud scrapers. The difference from Embodiment 1 is that in this embodiment, the outer chain plate 1 is composed of the following components by weight:

[0102] POM: 90 parts;

[0103] Polybutadiene epoxy resin: 60 parts;

[0104] Polyamide: 30 parts;

[0105] Glass fiber: 45 parts;

[0106] Glycerin: 2.5 parts;

[0107] Tert-butyl hydroquinone: 3 parts;

[0108] Talcum powder: 10 parts;

[0109] Carbon black: 3 parts;

[0110] Polyimide: 2.5 parts.

Embodiment 3

[0111] Embodiment 3: A production process of a plastic chain for a mud scraper. The difference from Embodiment 1 is that in this embodiment, the outer chain plate 1 is composed of the following components by weight:

[0112] POM: 100 parts;

[0113] Polybutadiene epoxy resin: 80 parts;

[0114] Polyamide: 35 parts;

[0115] Glass fiber: 50 parts;

[0116] Glycerin: 3 parts;

[0117] Tert-butyl hydroquinone: 4 parts;

[0118] Talc powder: 12 parts;

[0119] Carbon black: 4 parts;

[0120] Polyimide: 3 parts.

Abstract

The invention discloses a production process of a plastic chain for a mud scraper, and relates to the technical field of plastic chains. The technical point is: the plastic chain is composed of a plurality of chain links in series, and the chain links include an outer chain plate, an inner chain plate, a pin shaft, a sleeve and a retaining spring, and the structure of the outer chain plate and the inner chain plate, The size is the same, the inner sides of the two ends of the two inner chain plates are fixedly connected by sleeves, and the two ends of the two outer chain plates are respectively attached to the outer surfaces of the two ends of the two inner chain plates. The chain plates are connected by pin shafts inserted into the sleeves. The snap rings are located at both ends of the pin shafts and snapped into the sleeves. The outer surface of the outer chain plates is integrally provided with reinforcing ribs along its length direction. , the reinforcing rib is set to be hollow, by setting the reinforcing rib to be hollow, the fracture stress of the chain plate can be greatly enhanced, and the plastic chain is obtained by plasticizing the raw material through a special production process, so that the mechanical properties of the plastic chain are greatly improved improve.

Description

technical field [0001] The invention relates to the technical field of plastic chains, more specifically, it relates to a production process of plastic chains for mud scrapers. Background technique [0002] The plastic chain of the mud scraper is a transmission part that runs all the time in the sewage treatment tank. Due to the uncertain sewage in the sewage tank and the complex working environment conditions, the plastic chain of the mud scraper has great advantages in terms of strength, acid and alkali resistance, aging, self-lubrication, and ductility. , Thermal expansion and contraction, etc. have higher requirements. [0003] A modified POM plastic is disclosed in the Chinese invention patent with the authorized notification number CN103242621B, which consists of the following components in parts by weight: 40-80 parts of POM and 10-20 parts of PP. 5-10 parts of compatibilizer, 5-8 parts of graphite, 1-3 parts of light shielding agent, 0.2-0.5 parts of antioxidant.
