Abstract

The utility model discloses an arrangement structure of a calendaring forming roll set of a PET (Polyethylene Terephthalate) plate production line, which can increase the heating area of a belt blank. The arrangement structure comprises a pair of cooling calendaring rolls, a front forming heating roll and a back forming heating roll, wherein the pair of cooling calendaring rolls are mutually parallel and are sequentially arranged on a stand; and the front forming heating roll, the cooling calendaring rolls and the back forming heating roll are mutually staggered in a vertical direction. According to the arrangement structure of the calendaring forming roll set of the PET plate production line, disclosed by the utility model, the front forming heating roll, the cooling calendaring rolls and the back forming heating roll are mutually stacked in the vertical direction, so that coatings of the belt blank, the front forming heating roll and the back forming heating roll are increased, and the heating area of the belt blank is increased, thus the belt blank can obtain more heat, and the shaping of finished-product plate materials is ensured.

Description

The arrangement of the press polish setting roll group of PET board assembly line

Technical field

The utility model relates to the production line of PET plate, refers more particularly to the arrangement of the press polish setting roll group of PET board assembly line.

Background technology

Present PET board assembly line, its structure generally includes: string is located at extruder, press polish calibrator, trimming device, film covering device and shearing device together.The press polish setting roll group of said press polish calibrator comprises: be successively set on a pair of cooling press smooth roll that is parallel to each other and forward and backward typing warm-up mill on the frame.In the production process of PET plate; The PET strip blank of extruding from the extruder die orifice is through forward and backward typing warm-up mill the time; The coating area of PET strip blank and forward and backward typing warm-up mill is less, causes the heating surface area of PET strip blank less, makes that the received heat of PET strip blank is less; Meet thicker PET plate, just can not be to its good typing.

The utility model content

The utility model technical problem to be solved is: the arrangement of press polish setting roll group that a kind of PET board assembly line of the heating surface area that can increase made-up belt is provided.

In order to solve the problems of the technologies described above; The technical scheme that the utility model adopted is: the arrangement of the press polish setting roll group of PET board assembly line; Comprise: be successively set on a pair of cooling press smooth roll that is parallel to each other and forward and backward typing warm-up mill on the frame, preceding typing warm-up mill and cooling press smooth roll stagger with back typing warm-up mill in vertical direction each other.

The beneficial effect of the utility model is: the utility model increases the coating face of made-up belt and forward and backward typing warm-up mill through preceding typing warm-up mill and cooling press smooth roll are staggeredly arranged with back typing warm-up mill in vertical direction; Increased the heating surface area of made-up belt; Make made-up belt can obtain more received heat, guarantee the typing of finished product sheet material.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Among the figure: 1, cooling press smooth roll, 2, the cooling press smooth roll, 3, preceding typing warm-up mill, 4, back typing warm-up mill, 5, made-up belt.

The specific embodiment

Below in conjunction with accompanying drawing, describe the specific embodiments of the utility model in detail.

As shown in Figure 1; The arrangement of the felt wrapped roll group of the described PET board assembly line of the utility model; Comprise: be successively set on a pair of cooling press smooth roll 1 that is parallel to each other and 2 and preceding typing warm-up mill 3 and back typing warm-up mill 4 on the frame, preceding typing warm-up mill 3 and cooling press

smooth roll

1 and 2, the back warm-up mill 4 of finalizing the design staggers in vertical direction each other.

Above-mentioned preceding typing warm-up mill 3 and cooling press

smooth roll

1 and 2, back warm-up mill 4 structure that is staggeredly arranged of finalizing the design; Increased the coating face of made-up belt 5 with forward and backward typing warm-up

mill

3 and 4; Increase the heating surface area of made-up belt 5, made made-up belt 5 can obtain more received heat, guaranteed the typing of finished product sheet material.

Claims

1.PET the arrangement of the press polish setting roll group of board assembly line; Comprise: be successively set on a pair of cooling press smooth roll that is parallel to each other and forward and backward typing warm-up mill on the frame, it is characterized in that: typing warm-up mill and cooling press smooth roll stagger with back typing warm-up mill in vertical direction each other before described.
