Abstract
Description
Technical Field
[0001] This utility model relates to a winding device for roll flooring, and particularly to a winding device for roll flooring. Background Technology
[0002] Roll flooring is a popular lightweight flooring material on the market. It is made primarily from polyvinyl chloride and its copolymer resins, with the addition of fillers, plasticizers, stabilizers, colorants, and other auxiliary materials. It is produced on a continuous sheet substrate through coating, calendering, extrusion, or compression processes. Because roll flooring is light and thin, it is usually stressed on one side during the rolling process, resulting in poor unfolding performance and sometimes wrinkles. This reduces the rolling quality of the roll flooring and, more seriously, affects the overall roll finish. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a reasonably designed roll-up device for roll flooring that can withstand double-sided force and unfold while being pressed, in order to overcome the shortcomings of the existing technology.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A roll flooring winding device is characterized by comprising a frame and a winding roller mounted on the frame. A support plate for supporting the roll flooring is provided below the winding roller. The support plate is horizontally positioned, and rotating shafts parallel to the axis of the winding roller are provided on both sides of the support plate. The rotating shafts are mounted on the frame via bearings. A torsion spring for lifting the support plate is installed on one of the rotating shafts. A pressure roller pressing against the support plate is provided above the support plate on the flooring inlet side. The roller shaft of the pressure roller is connected to a rotating arm via bearings, and the rotating arm is rotatably mounted on the frame. The pressure roller is an elastic rubber roller that is larger in the middle and smaller at both ends. An elastic plate that cooperates with the elastic rubber roller is laid flat on the upper surface of the support plate.
[0006] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the upper surface of the tray at the floor entrance is provided with a ramp that is inclined upward along the floor rolling direction, and baffles are provided on both sides of the ramp.
[0007] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the thickness of the elastic plate is 5mm-10mm.
[0008] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the difference between the middle diameter and the diameters at both ends of the elastic rubber roller is 10mm-30mm.
[0009] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the end of the rotating arm that is connected to the frame is provided with a retaining shaft, and a retaining groove that cooperates with the retaining shaft is provided on the frame. The rotating arm has a certain amount of room for movement, and the cooperation between the retaining shaft and the retaining groove facilitates loading and unloading.
[0010] Compared with existing technologies, this invention uses a support plate that, through a rotating shaft and torsion spring, provides bottom support for the roll flooring. With the assistance of pressure rollers, both the upper and lower surfaces of the roll flooring are subjected to force, ensuring the roll flooring unfolds on both sides. The torsion springs and pressure rollers flatten the roll flooring. By setting the pressure rollers as elastic rubber rollers with a larger center and smaller ends, and by providing an elastic plate on the upper surface of the support plate that cooperates with the elastic rubber rollers, the roll flooring unfolds simultaneously with flattening, ensuring a good unfolding effect. The roll flooring winding device of this invention has a simple structure, is convenient to use and install, and produces good winding results. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0014] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0015] Reference Figure 1A roll flooring winding device includes a frame 3 and a winding roller 4 mounted on the frame 3. The winding roller 4 is mounted on the frame 3 at both ends via bearings. Below the winding roller 4 is a support plate 2 for supporting the roll flooring. The support plate 2 is horizontally positioned. On both sides of the support plate 2 are rotating shafts 8 arranged parallel to the axis of the winding roller. The rotating shafts 8 are mounted on the frame 3 via bearings. One of the rotating shafts is equipped with a torsion spring 9 that lifts the support plate upward. Above the support plate 2 on the flooring inlet side is a pressure roller 6 that presses against the support plate. The roller shaft of the pressure roller 6 is connected to a rotating arm 5 via bearings. The rotating arm 5 is rotatably mounted on the frame 3. One end of the rotating arm 5 that connects to the frame 3 is provided with a retaining shaft. The frame is provided with a retaining groove that cooperates with the retaining shaft for easy disassembly and assembly.
[0016] The pressure roller 6 is an elastic rubber roller that is larger in the middle and smaller at both ends. The upper surface of the support plate 2 is covered with an elastic plate that cooperates with the elastic rubber roller. The thickness of the elastic plate is 5mm-10mm. The difference between the diameter of the middle part of the elastic rubber roller and the diameter of the two ends should not be too large or too small, and 10mm-30mm is optimal, so as to achieve a better spreading effect.
[0017] The upper surface of the tray 2 at the floor entrance is provided with a ramp 10 that is inclined upward along the floor roll-up direction. Baffles 7 are provided on both sides of the ramp 10, which provides a good positioning and centering effect for the roll floor and ensures the later unfolding effect.
[0018] Because the pressure roller 6 naturally presses down under its own weight, and the pressure roller is an elastic rubber roller that is larger in the middle and smaller at both ends, it unfolds the roll flooring. Meanwhile, the support plate 2 is lifted upwards under the action of the torsion spring. The roll flooring is flattened through the cooperation of the pressure roller and the support plate. The elastic force of the torsion spring can be selected according to the weight of the support plate and the pressure roller. It is best to choose a torsion spring with an elastic force slightly greater than the sum of the weights of the two to ensure the rolling effect of the roll flooring. The winding device described in this utility model has a simple structure and is easy to use.
[0019] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
