Problems solved by technology

[0014] The above traditional processing technology has the following problems: due to the change of the ratio of PVC ingredients and calcium powder, the performance of the material will change, which will lead to the control of the foaming process of the material and the control of the film coating process of the material need to change accordingly
After the finished product blank is discharged from the high-temperature mold, it directly enters the high-temperature roller shaft. During the entire calendering and embossing process, the blank is always in a high-temperature state, which will affect the performance of calendering and embossing
Similar to the adverse effects mentioned above, there are problems such as the embossing cannot be pressed, or the pattern rebounds after the embossing is finished.

Embodiment 1

[0052] This embodiment provides a calender, which is used for one-time molding production of WPC wood-plastic flooring, and can complete foaming of the material to be processed, embossing or embossing on both sides of the bottom surface and the top surface, etc. Molding treatment. In this embodiment, WPC wood-plastic foamed floor is used as the material to be processed. In actual application, the material to be processed is not limited to the foamed floor.

[0053] The calender includes a machine base 1 and a set of calendering rollers arranged on the machine base 1 . According to the material processing flow (foamed floor in this embodiment), the calendering roller group sequentially includes a mirror roller group and an embossing roller group for double-sided embossing of the foamed floor.

[0055] Wherein, the main calender roll set refers to a roll set composed of calender rolls including mir...

Embodiment 2

[0086] This embodiment provides a foam floor production line using the calender in Embodiment 1 for foam floor production.

[0087] specific reference Figure 8According to the production process of the product, it includes a mixer 14 (shown in the figure as a mixer silo, which is used to simplify the representation of the mixer), a feeder 15, an extruder 16, a mold 17 and a calender 18 , the calender 18 in the calender embodiment 1, the structure thereof will not be repeated here.

[0088] The mixer 14 is used for mixing powder materials, and various materials used to produce the foamed substrate layer are introduced into the mixer 14 and stirred and mixed at a high speed. The mixed material after stirring is put into the feed bin of the spring feeder 15, and then fed to the hopper of the extruder by the rotation of the spring feeder 15.

[0089] It should be noted here that since the floor is made of multi-layer composite materials, two sides of the foam base layer are res...

Embodiment 3

[0095] This embodiment provides a production process for one-time molding of foamed flooring. The process specifically includes: one-step forming-health-preserving-cutting-grooving-testing and packaging-palletizing-warehousing and packing. Compared with the traditional production process, this process omits the steps of gluing and laminating, saving equipment and land occupation space.

[0096] Concrete technological process comprises the following steps:

[0097] Before the start-up of the production line, the mixer 14, the feeder 15, the extruder 16, the mold 17 and other temperature-operated equipment are preheated and kept warm in advance. The preheating time depends on the requirement. In this embodiment, the preheating time is 2 hours. The purpose of heating is to make the material change from the previous powder to the solution before starting the work of mixing and extrusion. The stability of preheating is between 150°C and 180°C. In this embodiment, 150°C, 160°C an...

Abstract

A calender comprises a machine base and calender roller groups arrayed on the machine base. The calender is characterized in that each calender roller group comprises a main calender roller group andan embossing roller group for embossing to-be-machined materials; each main calender roller group and the corresponding embossing roller group are spaced at a certain distance so that the materials can be cooled before entering another roller group form one roller group. The calender can realize the better embossing effect. The calender is used for production of a foaming floor so that integratedproduction of the foaming floor can be realized.

Description

technical field [0001] The invention relates to a processing machine, a foam floor processing production line and a one-shot molding production process of the foam floor. Background technique [0002] Compared with the traditional wooden floor, the foam floor has the following advantages: (1) soft texture, good moisture-proof and waterproof performance, good elasticity, good elastic recovery under the impact of heavy objects, and not easy to damage; (2) green and environmentally friendly, is a (3) It has good flame retardancy and high safety factor; (4) The cost is low, and it is cheaper than wooden flooring; etc. Based on the above, foam flooring has great development prospects and application space. [0003] Foam flooring is usually produced by composite processing of multi-layer materials. For example, taking WPC foam flooring as an example, it usually includes a middle foam layer and a solid layer covering both sides of the middle foam layer. The surface of the solid l...
