Embodiment 1

[0045] Such as Figure 1 to Figure 3 shown. A waxing base paper processing system for food packaging, comprising an unwinding device 1 and a waxing box 2 arranged in sequence, a preheating assembly 21 is arranged at the inlet of the waxing box 2, and a cooling assembly is arranged at the outlet 22. It is characterized in that, the waxing box 2 is also provided with:

[0046] Stretching assembly 23, said stretching assembly 23 is located between comprising said preheating assembly 21 and said cooling assembly 22, and it comprises the rotating roller a231 that is arranged in sequence along the base paper conveying path and is used for forward conveying base paper and rotating roller a231. The roller b232, correspondingly fixedly installed on the rotating roller a231 and the mounting seat 233 at both ends of the rotating roller b232, several groups of friction roller mechanisms 234 installed on the mounting seat 233 in a circular array, correspondingly fixedly installed on the r...

Embodiment 2

[0071] Such as Figure 12 As shown, a kind of food packaging wax base paper processing technology of the second embodiment of the present invention is described with reference to the first embodiment, comprising the following steps:

[0072] Step 1: base paper unwinding, unwinding equipment 1 unwinds the base paper to be waxed;

[0073] Step 2: Preheating the base paper. After Step 1, the base paper is transported to the preheating assembly 21 for preheating treatment, and the preheated base paper is transported between the rotating roller a231 and the rotating roller b232;

[0074]Step 3: Stretching the base paper. After step 2, the turning roller a231 and the turning roller b232 are rotated to transport the base paper forward. At the same time, under the action of the driving component a235 and the driving component b236, they are correspondingly arranged on the turning roller a231 The friction roller mechanisms 234 on both sides are reversed and produce oblique rearward te...

Abstract

The invention relates to a waxing base paper processing system for food packaging and its technology, comprising unwinding equipment and a waxing box, the inlet and outlet of the waxing box are respectively provided with a preheating assembly and a cooling assembly, waxing The box is also equipped with a stretching assembly and a waxing assembly; the stretching assembly includes a rotating roller a and a rotating roller b arranged sequentially along the base paper conveying path, mounting seats fixedly installed at both ends of the rotating roller a and rotating roller b, and a circular array rotating Several groups of friction roller mechanisms installed on the mounting base, the driving mechanism a fixedly installed in the rotating roller a and driving the friction roller mechanism to move in the opposite direction with the rotating roller a, and correspondingly fixedly installed in the rotating roller b and driving the friction roller mechanism and the rotating roller a The driving mechanism b that rotates the rotating roller b in the same direction; the waxing assembly includes a coating mechanism that is located directly above the rotating roller b and is power-connected with the rotating roller b, a filter mechanism that is swinging left and right above the coating mechanism, and a power-connected filter mechanism; The limit mechanism of the coating mechanism.

Description

technical field [0001] The invention relates to the technical field of base paper processing, in particular to a food packaging waxing base paper processing system and its technology. Background technique [0002] Waxed paper is widely used in food, medicine, sanitary products, stationery, measuring tools, knives and other packaging. With the continuous improvement of people's living standards and the increasing emphasis on food hygiene and safety, the quality requirements for paper-based waxed products are also continuously increasing. The traditional wax paper production technology mainly includes: immersion waxing method, this method is to first completely immerse the paper into the molten wax, and then squeeze the excess wax off the surface of the paper through a pair of extrusion rollers. Resulting in uneven wax application. [0003] The invention patent with the Chinese patent application number CN201410323273.X discloses a high-speed waxing device, which includes a ...
