Abstract
The utility model provides a five-roller calender. The problem that a sheet is difficultly stripped can be effectively solved, and then cold scars are reduced. The five-roller calender comprises a machine frame, wherein a calendering device is arranged on the machine frame; five calendering rollers which are arrayed in the form of inverse L are arranged on the calendering device; a stripping device is arranged in the horizontal direction of the calendering roller at the top end; five calendering rollers are arranged on the calendering device; an abrasive material used for reducing the adhesion amount of an oily precipitate on the stripping rollers is arranged on the surfaces of the stripping rollers; and a cooling device used for reducing the temperature of the stripping rollers is also arranged on the stripping device. Due to the adoption of the sand-spraying stripping roller, the chances that the sheet is adhered on the surface of the stripping rollers are greatly reduced; and the adhesion amount of the oily precipitate on the stripping rollers can be reduced at the same time because cooling water is filled through the cooling device to control the temperature. Therefore, the problem that the sheet is difficultly stripped is solved, the cold scars are reduced, and the quality of the sheet is greatly improved.
Description
Technical field
The utility model relates to a kind of plastics machinery, particularly a kind of five roll calendars.
Background technology
In plastic industry, calender and interlock subsidiary engine thereof are one of basic equipments in plastics, the rubber production process, are mainly used in the machine-shaping of thermoplastic at present.Compare with extrusion molding, the goods that adopt rolling process to produce have very big advantage at aspects such as thickness, accuracy and each item mechanical properties.Calender is through certain roller heating various plastic sheetings of rolling processing and plastic sheet of arranging; Existing calender is considered to solve roller stress deformation problem through the arrangement mode of conversion roller more; Thereby optimize the import and export mode of material, but but be difficult to overcome the blemish of goods, have brilliant point, flow liner, cold shut and crow's feet like the surface; Have a strong impact on the quality and the class of sheet material, restricted the development of sheet material processing industry.
Summary of the invention
The utility model can not be controlled the shortcoming of sheet material surface quality effectively to having calender now, and a kind of five roll calendars are provided, and can solve sheet material effectively and peel off difficult problem, and then reduce the generation of cold shut.
For achieving the above object, the utility model is taked following technical scheme:
A kind of five roll calendars; Comprise frame, on frame, be provided with calender device, on calender device, be provided with 5 and be the stack that anti-L type is arranged; On the horizontal direction of top stack, be provided with stripping off device; On stripping off device, be provided with 5 stripper roll, the stripper roll surface is provided with the abrasive material that is used to reduce oily precipitate adhesive capacity on the stripper roll, on stripping off device, also is provided with the cooling device that is used to reduce the stripper roll temperature.
Above-mentioned stripping off device is fixedly connected with the calendering subsidiary engine, on the calendering subsidiary engine, is provided with at least two chill rolls; There are 4 vertically to arrange in the above-mentioned stack, remain 1 along continuous straight runs and arrange; Stripper roll on the above-mentioned stripping off device and the S-type arrangement of the stack on the calender device.
When sheet material left stack arrival stripper roll, general stripper roll was a plain roller in the calendering formation process, and mirror finish is carried out on the roller surface; Adhere to easily the oily precipitate in the processing, when stripper roll adhered to a certain amount of oily precipitate, the heterogeneity phenomenon appearred in sheet material peel off easily; Peeling off earlier of stripper roll both sides; Middle obvious hysteresis and precipitate are oilies, adhere to the assorted point of outstanding crystalline substance easily, when certain brilliant assorted point is adhered to when then peeling off; The tablet of its front will be pullled it and is stripped from up to it, thereby has formed cold shut.Because separating out of grease is inevitably in the calendered sheet process, for the generation that reduces cold shut wiping stripper roll regularly, but increased workload again and influence ordinary production, the while, online wiping stripper roll can cause danger.
The utility model changes into the occurrence probability that the sandblast stripper roll reduces sheet-adhesion stripper roll surface greatly with light face stripper roll; Feed the cooling water temperature control through cooling device simultaneously; Can reduce the adhesive capacity of oily precipitate on the stripper roll; Thereby solved sheet material and peeled off difficult problem, and then reduced the generation of cold shut, improved sheet quality greatly.
Description of drawings
Fig. 1 is the front view of the utility model.
Description of reference numerals: 1-frame; The 2-calender device; 21-first stack; 22-second stack; 23-the 3rd stack; 24-the 4th stack; 25-the 5th stack; The 3-stripping off device; 31-sandblast stripper roll; The 32-cooling device; The 33-first sandblast stripper roll; 4-rolls subsidiary engine; The 41-chill roll.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model content is described further.
As shown in Figure 1; The utility model is made up of frame 1, calender device 2 and stripping off device 3; Calender device 2 comprises that 5 are the stack that anti-L type is arranged; Along continuous straight runs is provided with first stack 21; Vertically be provided with second stack 22, the 3rd stack 23, the 4th stack 24 and the 5th stack 25 from bottom to top successively near first stack, 21 places, stripping off device 3 is provided with horizontal 5 sandblast stripper roll 31 and cooling device 32, on calendering subsidiary engine 4, is provided with a plurality of chill rolls 41.
As shown in Figure 1; The rolling processing process of the utility model is following: will mix various plastic additives, heating plasticizing, near the sheet material of viscous state by getting into the 3rd stack 23, the 4th stack 24 and the 5th stack 25 between first stack 21 and second stack 22; Carrying out five roll-ins through these five the formed gaps of stack that rotate in opposite directions prolongs; Under extruding force between the stack and shearing force effect; Make sheet material produce certain extension distortion, slowly cool off again through calendering subsidiary engine 4 through 5 sandblast stripper roll 31 and a plurality of chill rolls 41 again and obtain required specification, continuous sheet material products.
As shown in Figure 1; The part volatilization in preorder high temperature extrusion process of the lubricant on the stack in the calendering formation process because when sheet material does not also arrive the 5th stack 25; Cause external lubrication not enough, cause sheet material on sandblast stripper roll 31, to peel off heterogeneity, the processing temperature of adding the 5th stack 25 is higher relatively; It is tighter to cause sheet material to coat; Be difficult for peeling off, if the temperature of sandblast stripper roll 31 is higher, sheet material still might be in viscous state after arriving sandblast stripper roll 31; And also have precipitate on the sandblast stripper roll 31 or volatilization gas is condensate in other material on the sandblast stripper roll 31, thereby cold shut appear at the 5th stack 25 and the first sandblast stripper roll 33 ' between.Adopt sandblast stripper roll 31 to reduce the occurrence probability on sheet-adhesion sandblast stripper roll 31 surfaces greatly; Feed the cooling water temperature control through cooling device 32 simultaneously; Reduce the adhesive capacity of oily precipitate on the sandblast stripper roll 31, made sheet material peel off easily, reduce the generation of cold shut.
