Abstract
The invention relates to an industrial rubber covered roller. A teflon rubber covered roller comprises a roller body and a metal core rod. The roller body employs a cylindrical sleeve pipe made from a teflon material and with a wall thick of 10-100 mm. The metal core rod passes through the sleeve pipe and is fixed with the sleeve pipe; and two ends of the core rod are respectively provided with a shaft head. The rubber covered roller provided by the invention can be widely applied to the industries of chemistry, smelting and printing, overcomes disadvantages of a traditional rubber covered roller, such as short usage life and easy ageing, and substantially reduces production cost for the enterprises using the rubber covered roller, especially for industries like papermaking, galvanizing and pickling, etc. Accordingly, as a product with merits of energy saving, consumption reduction and high performance, the teflon rubber covered roller has promising market prospects.
Description
Technical field
The present invention relates to a kind of industrial rubber roll.
Background technique
Existing rubber roller for industry is take metal or other materials as core, covers the roller shape goods that rubber is made through sulfuration outward.This rubber roller for industry use a corrosion, aging in harsh industrial environment, and mechanical property is relatively poor because wear-resisting property and resistance to heat are bad, and working life is shorter.
Chinese invention patent (application number: 201210351099, the applying date: on September 20th, 2012) disclose a kind of rubber roller for industry, comprise metal-cored, the described metal-cored outer layer glue that is coated with, described outer layer glue and metal-cored between be provided with the hard glue-line, described outer layer glue outer wall is fitted with the polytetrafluoroethylene film layer.This patent only is on the rubber roll surface polytetrafluoroethylene film layer to be set, the polytetrafluoroethylene film laminating closes on the outer layer glue, the thickness low LCL of polytetrafluoroethylene film layer causes peeling off easily, has also increased in addition the difficulty of processing of product by multilayer outer layer glue and hard glue-line are set.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this invention is to provide a kind of teflon rubber roll, this rubber roll has the characteristics such as strong acid-base-resisting, high-low temperature resistant (± 200 ℃), ageing-resistant long service life.
In order to realize above-mentioned purpose, the present invention has adopted following technological scheme:
The teflon rubber roll, this rubber roll comprises roll body and metal mandrel, and roll body adopts the cylinder-shaped sleeve of teflon material, and the wall thickness of sleeve pipe is at 10 ~ 100mm, described metal mandrel is located in the sleeve pipe and with sleeve pipe and fixes, and is respectively equipped with spindle nose at the two ends of plug.
As preferably, the wall thickness of described sleeve pipe is at 20 ~ 50mm.
As preferably, the surface of described metal mandrel is axially arranged with sword groove tooth, and metal mandrel and sleeve pipe are tightly fixed by sword groove tooth.
As preferably, described metal mandrel comprises metal tube and connection end, and metal tube is set in the sleeve pipe, and connection end is set in the two ends of metal tube, and welds mutually with the metal tube inwall, and described spindle nose is arranged on the connection end.
As preferably, the outer surface of described connection end is arranged with the teflon cover, the end face of teflon cover sealing metal tube, and the end face of teflon cover is concordant with the end face of sleeve pipe, and welds mutually with box face.
As preferably, the wall thickness of described metal tube is 10 ~ 40mm.
As preferably, described teflon sleeve wall thickness is 10 ~ 30mm.
The present invention is owing to adopted above technological scheme, and the product antiseptic property is powerful, can wear out medium-term and long-term use of any acid-base solution, does not corrode, and indeformable, superpower high and low temperature resistance can normally use under ± 200 ℃ of environment.It is short working life that this product has solved traditional rubber roll, the situation of easy damaged.Rubber roll of the present invention can be widely used in the industries such as each chemical industry, papermaking, smelting, printing, has the characteristics such as strong acid-base-resisting, ageing-resistant long service life.Particularly in the corrosive environments such as strong acid and strong base, can reach the 12-24 month working life.Overcome general rubber roll and greatly enhanced productivity less than 60 days situation working life in corrosive environment, saved cost of production, increased the performance of enterprises etc.Traditional product, make take rubber as raw material, anticorrosive power is poor, not wear-resisting, only have one month service time, this cost of goods manufactured is the same with traditional product, but can reach 1 year the service time of this product, greatly reduces the cost of production of rubber roll applying unit, and the contaminativity of rubber is large, and contamination-free produced during this product used.
Rubber roll of the present invention can be widely used in the industries such as chemical industry, smelting, printing, and it is short working life to have overcome traditional rubber roll, and the easy shortcoming such as aging greatly reduces the cost of production of rubber roll applying unit, especially is applicable to papermaking, and is zinc-plated, the industries such as pickling.Therefore, possess energy-saving and cost-reducing and high performance product as one, market prospects are boundless.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is made a detailed explanation.
Teflon rubber roll as shown in Figure 1, this rubber roll comprises roll body and metal mandrel, roll body adopts the cylinder-shaped sleeve 1 of teflon material, the wall thickness of sleeve pipe 1 is at 30mm, described metal mandrel is located in the sleeve pipe 1 and with sleeve pipe 1 and fixes, the surface of described metal mandrel is axially arranged with sword groove tooth, and metal mandrel and sleeve pipe 1 are tightly fixed by sword groove tooth.Metal mandrel comprises metal tube 2 and connection end 3, the wall thickness of metal tube 2 is 20mm, metal tube 2 is set in the sleeve pipe 1, described connection end 3 is set in the two ends of metal tube 2, and weld mutually with metal tube 2 inwalls, spindle nose 5 is set on the connection end 3, and is arranged with teflon cover 4 at the outer surface of connection end 3.The wall thickness of described teflon cover 4 is 13mm, and teflon overlaps the end face of 4 closed metal bodys 2, and the end face of teflon cover 4 is concordant with the end face of sleeve pipe 1, and welds mutually with sleeve pipe 1 end face.
