Abstract
The utility model relates to a plastic mechanical device, in particular to a five-roller flattener which is used to manufacture rigid PVC plastic sheet, and comprises a frame work, a roller device, a distance adjusting equipment and an actuating device, wherein the roller device and the distance adjusting equipment are provided at the frame work, the roller device is composed of a roller I, a roller II, a roller III, a roller IV, and a roller V, the roller I and the roller II are arranged horizontally, the roller II, the roller III, the roller IV, and the roller V are arranged perpendicularly, The roller I, the roller II and the roller III are all provided with a distance-adjusting device which adjusts the distance with the adjacent roller, and the roller V is provided with a distance-adjusting device which adjusts the distance with the roller IV. The utility model is characterized in that the frame work is provided with an adjusting device which is deviated from a shaft center of the roller IV and a roller V shaft center. The utility model has the advantages of simple structure, strong practicability. Besides, on the condition of ensuring the consistency and quality of the products, the utility model not only downsizes the cost of manufacturing rollers, but also meets various demands of the manufacturing sheet materials with different thickness.
Description
Technical field:
The utility model relates to a kind of plastics machinery device, especially a kind of five roll calendars that are used for processing rigid PVC plastic sheet.
Background technology:
Existing five roller plastic calenders, mainly constitute by frame, roller bench, roll-setting gear and transmission device, described roller bench and roll-setting gear are arranged on the frame, roller bench is made of roller I, roller II, roller III, roller IV and roller V, described roller I and roller II are horizontally disposed with, the vertical from top to bottom setting of roller II, roller III, roller IV and roller V, the arrangement of roller bench is " Γ " shape.Roller I, roller II, roller III and roller V are provided with the adjusting device with adjacent roller spacing, and roller IV is not provided with distance adjusting means.In process of production, owing to be subjected to the influence of material extruding, roller will produce the strain of trace, and especially last is comparatively obvious to roller, and the hard PVC sheet material that it processes will thick middle, and both sides approach.For overcoming described phenomenon, modal way is that roller IV is processed into (usually this roller being called olive shape) broad in the middle small in ends, with the roller strain in the compensation process.The olive shape roller can overcome the phenomenon of roller strain in a sense.But its weak point is: 1. olive shape roller difficulty of processing is big, the cost height; 2. must often adjust and safeguard, increase maintenance cost; 3. (for example: the 0.1-0.8mm) requirement of sheet material processing be difficult to satisfy various different-thickness.
The utility model content:
The purpose of this utility model is to overcome the weak point of the above five roller plastic calender, a kind of device that compensates the roller strain in the plastic calender process is provided, under the prerequisite that guarantees product uniformity quality, both reduce the processing cost of roller, and can satisfy the requirement of various different-thickness sheet material processing again.
The utility model, mainly constitute by frame, roller bench, roll-setting gear and transmission device, described roller bench and roll-setting gear are arranged on the frame, roller bench is made of roller I, roller II, roller III, roller IV and roller V, described roller I and roller II are horizontally disposed with, the vertical from top to bottom setting of roller II, roller III, roller IV and roller V, the arrangement of roller bench is " Γ " shape.Roller I, roller II, roller III and roller V are provided with the adjusting device with adjacent roller spacing, it is characterized in that: on frame 6, be provided with the adjusting device of roller IV axle center and roller V axle misalignment, i.e. the axle skewing mechanism.
The utility model, the adjusting device of described roller V axle misalignment is by making the bearing spider that moves horizontally and the spiro rod regulating device of bearing spider displacement is constituted on support.
It is different and different that the utility model, described roller IV axle center and the angle [alpha] of roller V axle misalignment are looked the PVC sheet thickness, and generally speaking, the PVC sheet thickness is thick more, and the bias at axle center is just big more.
The utility model has following characteristics: 1. roller IV adopts common straight tubular roller to get final product, and reduces technology and the expense of making the olive shape roller; 2. the maintaining expense that guarantees olive shape and provide is provided; 3. by the adjusting of bias, can satisfy the requirement of various different-thickness sheet material processing.
Description of drawings:
Fig. 1 is the structure principle chart of embodiment.Fig. 2 is roller IV and the axle of roller V intersects schematic diagram.
Among the figure, 1, the axis angle of roller I 2, roller II 3, roller III 4, roller IV 5, roller V6, frame 7, adjusting device 8, bearing spider 9, spiro rod regulating device 40, roller IV axis 50, roller V axis alpha, roller IV and roller V.
The specific embodiment:
With reference to accompanying drawing, these five roller plastic calenders, mainly constitute by frame 6, roller bench, roll-setting gear and transmission device, described roller bench and roll-setting gear are arranged on the frame, roller bench is made of roller I, roller II, roller III, roller IV and roller V, described roller I and roller II are horizontally disposed with, the vertical from top to bottom setting of roller II, roller III, roller IV and roller V, and the arrangement of roller bench is " Γ " shape.Roller I, roller II and roller III are provided with the adjusting device with adjacent roller spacing, roller V is provided with the adjusting device 7 with roller IV spacing, above-described structure is same as the prior art, unlike the prior art be: on frame 6, be provided with the adjusting device of roller IV axle center and roller V axle misalignment, promptly the axle skewing mechanism, the adjusting device of described axle misalignment is by making the bearing spider 8 that moves horizontally and the spiro rod regulating device 9 that can make the bearing spider displacement constitutes on support, the angle adjustable α of described roller IV axle center and roller V axle misalignment is the 0-2 degree.
Claims (3)
