Abstract

The utility model provides a paper heating device which comprises a vat drying cylinder. The paper heating device is characterized by further comprising a heating plate, the heating plate and the vat drying cylinder are located on two sides of paper respectively, the heating plate is provided with an infrared heating surface, and the heating surface of the heating plate is parallel to the paper. The paper heating device has the advantages of being simple in design, little in investment and convenient to operate, remarkably improving quality of finished product paper and reducing curl and cost.

Description

A kind of paper heating device

Technical field

The utility model relates to the paper heating device that uses in a kind of paper production process, a kind of paper heating device that especially in the process of producing the tipping body paper, uses.

Background technology

Especially producing in the process of tipping body paper in traditional paper production; Make the l Water Paper page or leaf dry through vat drying cylinder flow process, its concrete vat drying cylinder technological process is shown in accompanying drawing 1, and the l Water Paper page or leaf is through the applying glue of top sizing device; Page after the applying glue contacts with felt; Part moisture is adsorbed by felt, and the l Water Paper page or leaf is crushed on the drying cylinder and heats high temperature drying under the pressure of carrying roller then.There is following shortcoming in this technological process: only through the drying of a vat drying cylinder single face heating, its inside is even to unbalanced stress for the l Water Paper page or leaf, and dried page is prone to when machine down and stretches the back and curl; Particularly the cigarette body paper of usefulness is printed in production, when advancing the vat drying cylinder, needs top sizing, sticks with paste cylinder when top sizing concentration is big easily, and the former paper product of producing of tipping is easier to be curling in use, has caused printing obstacle and bonding difficulty.

Summary of the invention

The purpose of the utility model is to overcome the problem of curling, cause printing obstacle and bonding difficulty after page stretches after the production of conventional vat drying cylinder, provides a kind of and can avoid the curl paper heating device of problem of finished product paper.

For addressing the above problem, the technical scheme that the utility model adopted is:

A kind of paper heating device comprises the vat drying cylinder, it is characterized in that: also comprise heating plate, said heating plate and vat drying cylinder lay respectively at the paper both sides.

Say that further said heating plate has an infrared ray heating surface.

Say that further the heating surface and the paper of said heating plate laterally arrange.

Owing to adopted technique scheme, compared with prior art, the utility model has the advantages that:

(1) simplicity of design, small investment, easy to operate;

(2) obviously improve the quality of finished product paper, alleviate curling;

(3) adopt behind this paper heating device and can under the situation that does not reduce paper quality, reduce production cost through improving content of starch in applying glue concentration or the slurry.

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.

Description of drawings

Accompanying drawing 1 is the structural representation of traditional vat drying cylinder technology;

Accompanying drawing 2 is example structure sketch mapes of a kind of paper heating device of the utility model.

The specific embodiment

Embodiment: shown in accompanying drawing 2, a kind of paper heating device comprises heating plate 5, vat drying cylinder 3, felt 2 etc., and heating plate 5 lays respectively at paper 4 both sides with vat drying cylinder 3.

In the present embodiment, heating plate 5 has an infrared ray heating surface, and this heating surface and paper 4 laterally arrange, and heating surface is rectangle, and the width of its length and paper 4 is approaching, can view picture page 4 evenly be heated.

Aborning; Paper 4 at first passes through 1 applying glue of top sizing device; Paper 4 after the applying glue is heated with predrying during through heating plate 5, and paper 4 mass dryness fractions appropriateness is increased, and paper 4 contacts with felt 2 subsequently; Part moisture is by felt 2 absorption, be crushed on the vat drying cylinder 3 at paper 4 under the pressure of carrying roller then heat at last, high temperature drying.

Heating through heating plate 5 of paper 4 and predrying, that has avoided after using single vat 3 to carry out the single face drying, causing is even to unbalanced stress, efficiently solves the problem that the paper finished product curls; This device also effectively reduces the phenomenon that drying cylinder is stuck with paste cylinder simultaneously, in actual production, can suitably improve the concentration of surface glue, perhaps increases the addition of starch in the slurry, can reduce cost.

The utlity model has simplicity of design, small investment, easy to operate, obviously improve the finished product paper quality, alleviate advantage curling, that reduce cost.

Claims (3)

1. a paper heating device comprises vat drying cylinder (3), it is characterized in that: also comprise heating plate (5), said heating plate (5) lays respectively at paper (4) both sides with vat drying cylinder (3).

2. a kind of paper heating device according to claim 1 is characterized in that: said heating plate (5) has an infrared ray heating surface.

3. a kind of paper heating device according to claim 1 and 2 is characterized in that: the heating surface of said heating plate (5) and paper (4) laterally arrange.
