Embodiment 1

[0021] Embodiment 1: This plastic calendering calender includes a feeding mechanism, a pressure roller 1, a cooling roller 5 and its control mechanism and power mechanism. Also include stripping roll 2 and calender roll 3 between pressing roll 1 and cooling roll 5; Calender rollers 3; calender rollers 3 are two upper and lower rollers, and the spacing can be adjusted by the control mechanism to compact plastic products with a certain temperature. There is also a cold release roll 4 between the calender roll 3 and the cooling roll 5, and the cold release roll 4 is next to the calender roll 3 below.

[0022] Roller 1 is seven rollers, distributed in an "M" shape, the second roller is on the right of the first roller, the third roller is on the right of the second roller, and the fourth roller is on the third Below the first pressing roller, the fifth pressing roller is on the right of the fourth pressing roller, the sixth pressing roller is under the fifth pressing roller, the ...

Embodiment 2

[0024] Embodiment 2: The calendering calender described in embodiment 1, its press roll 1 is six rolls, is " M " type distribution, and the second press roll is on the right side of the first press roll, and the third press roll is on the right side of the first press roll. Below the second pressing roller, the fourth pressing roller is on the right of the third pressing roller, the fifth pressing roller is under the fourth pressing roller, the sixth pressing roller is under the fifth pressing roller; stripping roller 2 On the upper right side of the sixth roller.

[0025] The material enters through the first pressing roll and the second pressing roll, is output from the sixth pressing roll through extrusion and drawing, enters between the two calendering rolls through the peeling roll, and enters the cooling roll device through the cold release roll.

Embodiment 3

[0026] Embodiment 3: The calendering calender described in embodiment 1, its pressure roll 1 is five rolls, is the distribution of inverted "L" shape, and the second pressure roll is on the right side of the first pressure roll, and the third pressure roll On the right of the second pressure roller, the fourth pressure roller is above the third pressure roller, and the fifth pressure roller is above the fourth pressure roller; peeling roller 2 is on the right side of the fifth pressure roller, peeling roller 2 For two parallel existence at the same time, the gap can be adjusted through the control mechanism.

[0027] The material enters through the first pressing roll and the second pressing roll, is output from the fifth pressing roll through extrusion and drawing, enters between the two calendering rolls through the peeling roll, and enters the cooling roll device through the cold release roll.

Abstract

The invention relates to a plastic processing equipment. It adds a stripping roller and felt wrapped roll between the plastic compression roller and the cooling roller, with the stripping roller close to the last compression roller, stripping the coarsely formed product from the compression roller, delivering it to the felt wrapped roll which can press the plastic part tight through the top and down two pieces by the control mechanism. There is a clod stripping roller between the felt wrapped roller and the cold roller. It can allow the plastic parts having smooth surface without bubbles.

Description

technical field [0001] The invention relates to a plastic processing equipment, in particular to a plastic calendering equipment. Background technique [0002] At present, the packaging industry is thriving, and plastic packaging has become an indispensable part of our lives. The plastic packaging of many toys is stamped from plastic sheets. [0003] Existing plastic plate processing machinery adopts two kinds of technologies, one is calendering technology, and the other is extrusion technology. Extrusion technology is relatively advanced, but its production equipment is expensive and the production cost is very high. The production cost of calendering technology is low, and most of the indicators of processed products can meet the demand. However, the surface quality of products processed by calenders on the market is poor, and ripples and bubbles will occur. Contents of the invention [0004] The object of th...
