Description

Technical Field

[0001] The utility model belongs to the technical field of suction cups, and in particular relates to a reinforcement pad used on a suction cup. Background Art

[0002] During the glass processing process, negative pressure suction cups are needed to lift the glass in order to move and transport the glass. Therefore, the performance of the suction cups is crucial to the processing quality and efficiency of the glass. However, for glass with uneven surfaces, such as Changhong glass, water ripple glass, wick glass, diamond glass and cloth-patterned glass, when the negative pressure suction cup lifts the glass, since the cutting machine needs to cut the smooth surface of the glass, the negative pressure suction cup is needed to absorb the pitted surface of the glass. In order to avoid lifting failure, the negative pressure suction cup is needed to tightly adsorb the pitted surface of the glass on the surface of the suction cup, so that the pitted surface of the glass will be deformed to a certain extent, leaving an imprint of the suction cup outline on the pitted surface of the glass, affecting the quality of the glass.

[0003] There is a device called silicone suction cup on the market, which is specially used to suck up glass with uneven surfaces. Compared with conventional negative pressure suction cups, this type of suction cup has an entire surface with a silicone layer, and the silicone layer and the suction cup surface are not removable.

[0004] Therefore, a reinforcing pad for a suction cup is proposed, which can be conveniently installed on a conventional negative pressure suction cup, so that the ordinary negative pressure suction cup can also suck up glass with uneven surfaces and avoid leaving marks on the glass. Utility Model Content

[0005] The purpose of the utility model is to provide a reinforcement pad for a suction cup to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A reinforcing pad for a suction cup, comprising:

[0008] An EVA foam layer, wherein the EVA foam layer is adhered and fixed to the surface of the suction cup body;

[0009] The EPE pearl cotton layer is adhered and fixed to the other side of the EVA foam layer.

[0010] Preferably, the thickness of the EVA foam layer is 3MM, and the thickness of the EPE pearl cotton layer is 5MM-6MM.

[0011] Preferably, a seamless cut is evenly formed on a side of the EPE pearl cotton layer away from the suction cup body, and the depth of the seamless cut is between 1.5 MM and 3 MM.

[0012] Preferably, the EVA foam layer and the EPE pearl cotton layer are bonded by double-sided tape, and the EVA foam layer and the suction cup body are bonded by double-sided tape.

[0013] Preferably, the EVA foam layer and the EPE pearl cotton layer are both provided with through holes, the through holes are opposite to the pores of the suction cup body, and the apertures thereof are not smaller than the apertures of the pores of the suction cup body.

[0014] Preferably, the outer diameters of the EVA foam layer and the EPE pearl cotton layer are the same as the outer diameter of the suction cup body.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] (1) The utility model provides an EVA foam layer and an EPE pearl cotton layer, wherein the EVA foam layer is used as a padding adhesive material and is mainly in contact with the surface of the suction cup. Since the EVA foam has the characteristics of being able to be cut arbitrarily, cushioning and shock-absorbing, and being easy to adsorb, it can reduce pressure, so that when the suction cup body lifts the glass with an uneven surface, the probability of marks on the glass can be reduced. The EPE pearl cotton has the characteristics of softness, cushioning, strong buoyancy, excellent weather resistance and smooth surface, so it can protect the glass in contact with it from being easily damaged, and further avoid marks on the glass with an uneven surface.

[0017] (2) The EVA foam layer in the utility model has the characteristics of tolerance, hot-melt bonding, and corrosion resistance, and can be directly bonded to the suction cup body by hot-melt bonding, or bonded to the suction cup body by double-sided tape. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 It is a schematic diagram of the structural disassembly of the utility model.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. It should be pointed out that the drawings are schematic and not drawn to scale. For the sake of clarity and convenience in the figures, the relative sizes and proportions of the parts shown in the figures are exaggerated or reduced in size, and any size is only exemplary and not restrictive.

[0022] Example:

[0023] See also Figure 1 As shown, a reinforcement pad for a suction cup comprises:

[0024] EVA foam layer 1, the EVA foam layer 1 is adhered and fixed to the surface of the suction cup body 3;

[0025] The EPE pearl cotton layer 2 is adhered and fixed to the other side of the EVA foam layer 1.

[0026] It can be seen from the above that by providing a reinforcing pad formed by the EVA foam layer 1 and the EPE pearl cotton layer 2, the characteristics of the EVA foam and the EPE pearl cotton are fully utilized. When the suction cup body 3 adsorbs the glass, it can reduce the pressure, making it difficult to produce marks on the glass surface, thereby avoiding affecting the quality of the glass.

[0027] Specifically, the thickness of the EVA foam layer 1 is 3MM, and the thickness of the EPE pearl cotton layer 2 is 5MM-6MM.

[0028] As can be seen from the above, in this application, the EVA foam layer 1 is used as a bottom adhesive material, which is mainly in contact with the surface of the suction cup to prevent the EPE pearl cotton layer 2 from sticking loosely. Therefore, the EVA foam layer 1 can be thinner, and the EPE pearl cotton layer 2 bears the main decompression function, so it needs to be thicker.

[0029] Specifically, by Figure 1 It can be seen that a seamless cut 21 is evenly formed on a side of the EPE pearl cotton layer 2 away from the suction cup body 3, and the depth of the seamless cut 21 is between 1.5 MM and 3 MM.

[0030] It can be seen from the above that by providing the seamless cutout 21, the portion of the EPE pearl cotton layer 2 that contacts the glass can be more easily embedded in the glass surface.

[0031] Specifically, the EVA foam layer 1 and the EPE pearl cotton layer 2 are bonded together by double-sided tape, and the EVA foam layer 1 and the suction cup body 3 are bonded together by double-sided tape.

[0032] It can be seen from the above that the EVA foam layer 1 and the EPE pearl cotton layer 2 can be adhered by the setting of the double-sided tape.

[0033] Specifically, by Figure 1 It can be known that both the EVA foam layer 1 and the EPE pearl cotton layer 2 are provided with through holes 4 , which are opposite to the pores of the suction cup body 3 , and whose apertures are not smaller than the apertures of the pores of the suction cup body 3 .

[0034] As can be seen from the above, the arrangement of the through hole 4 ensures that the air extraction of the air hole of the suction cup body 3 will not be affected.

[0035] Specifically, by Figure 1It can be seen that the outer diameters of the EVA foam layer 1 and the EPE pearl cotton layer 2 are the same as the outer diameter of the suction cup body 3 .

[0036] It can be seen from the above that the outer diameters of the EVA foam layer 1 and the EPE pearl cotton layer 2 are set to be the same as the outer diameter of the suction cup body 3 in order to prevent the EVA foam layer 1 and the EPE pearl cotton layer 2 from being scratched against other equipment when the suction cup body 3 moves. The outer shell of the suction cup body 3 can protect the EVA foam layer 1 and the EPE pearl cotton layer 2 from the side.

[0037] In actual use, the shape of the reinforcement pad needs to be designed according to the shape of the suction cup surface. Some suction cups have more than one air hole on their surface, which need to be avoided. In addition, while avoiding the air holes on the suction cup surface, the surface area of ​​the reinforcement pad needs to be as large as possible without exceeding the outer diameter of the suction cup surface, thereby increasing the force-bearing area and improving the decompression effect.
