Description

TECHNICAL FIELD

[0001] The utility model relates to a film uncovering appliance field, and relates to a film uncovering tool. BACKGROUND

[0002] The surface of the existing acrylic plate, metal plate and other plates is usually covered with a protective film for surface protection before transportation and use. The traditional film uncovering method requires an art knife to be inserted into the gap between the film and the plate surface from the edge of the plate to pick up the film, which has two technical defects: first, the blade needs to be precisely inserted into the gap between the film and the plate surface, which is time-consuming and requires high proficiency of the operator; second, the metal blade directly contacts the plate, which has the risk of scratching the plate, which may cause quality defects such as scratches on the surface of the product.

[0003] Therefore, in order to solve the above technical problems, a film uncovering tool with a simple structure needs to be designed. CONTENT OF THE UTILITY MODEL

[0018] The utility model will be further described below in combination with the embodiments and drawings. Figs. 1-4 The technical scheme of the utility model is further described.

[0019] Embodiment 1

[0020] A film uncovering tool, comprising a rubber main body 1, one side of the rubber main body 1 in contact with a product is a film uncovering surface 2, the film uncovering surface 2 is arranged in an arc shape and extends upward from the middle to both sides in the length direction.

[0021] As Figs. 1-4 The use principle of the utility model is as follows:

[0022] When the hand tool is placed on the film layer on the edge of the plate, the arc-shaped film stripping surface 2 is kept in continuous contact with the film layer by natural swinging of the wrist, and the friction coefficient between the rubber body 1 and the film layer is significantly greater than the friction coefficient between the film layer and the plate. Through the friction coefficient test, the friction coefficient between the rubber body 1 and the PET film is 0.85-1.2, which is significantly higher than the interfacial friction coefficient of the film layer and the acrylic plate (0.3-0.5) or the aluminum alloy plate (0.4-0.6). The difference in friction coefficient causes stress concentration in the film layer during peeling, which promotes the separation of the film layer in the preset direction. At the same time, the flexible contact of the rubber material can avoid damage to the surface of the plate. With a small angle of wrist rotation, continuous peeling of the film layer can be realized, and the operation flexibility is significantly improved.

[0023] As a further preferred embodiment, the upper end surface 11 and the lower end surface 12 of the rubber body 1 are symmetrically arranged, and the upper end surface 11 and the lower end surface 12 are both film stripping surfaces 2.

[0024] The tool adopts a bidirectional symmetric structure design of the upper end surface 11 and the lower end surface 12, and both ends are provided with standard film stripping surfaces 2. This design breaks through the one-way use limitation of the tool, and the operator does not need to distinguish the direction of the tool. The operator can flexibly select the operation surface according to the operation position, thereby effectively improving the operation efficiency.

[0025] As a further preferred embodiment, in the width direction, the middle part surface 21 of the film stripping surface 2 is horizontally arranged, and the two side surfaces 22 of the film stripping surface 2 are arranged in an arc shape extending downward.

[0026] The middle horizontal surface 21 provides a stable contact area (contact area ≥ 30mm 2 ), which ensures sufficient peeling friction, and the two side surfaces 22 extend in an arc shape downward (curvature radius R = 18mm). The two side surfaces 22 form a dynamic drag reduction structure during peeling. The combination of the curved surfaces ensures the peeling effect while reducing the rotation resistance of the tool, thereby achieving smooth operation.

[0027] As a further preferred embodiment, in the height direction, the rubber body 1 is symmetrically provided with a groove 13 at the middle part of the rubber body 1, and the width of the rubber body 1 increases from the center of the groove 13 outward.

[0028] The main body adopts a waist drum type cross section design, and is matched with the groove on the inner side. The structure is highly consistent with the natural holding form of the palm, which can reduce hand fatigue during long-time operation and improve the stability of holding.

[0029] As a further preferred embodiment, two groups of through holes 14 are symmetrically arranged on the inner side of the groove 13. The through holes 14 can be adapted to a rope preventing device. In a flow line operation, a wrist strap can be configured to realize tool positioning, prevent accidental falling, and ensure continuous work.

[0030] The preferred embodiments of the present application are described in detail above. It should be understood that those skilled in the art can make many modifications and changes without creative work according to the concept of the present application. Therefore, any technical solutions obtained by logical analysis, reasoning or limited experiments on the basis of the prior art according to the concept of the present application shall be within the protection scope defined by the claims.
