Description

Suction mark prevention suction cup

Technical Field

The utility model relates to a sucking disc technical field especially relates to a prevent inhaling trace sucking disc.

Background

In the process of processing and transporting the metal sheet, the metal sheet is often required to be sucked up by using a sucking disc and moved to a processing position, the sucking disc generally generates a suction force through vacuum, and the surface of the metal sheet sucked up by the sucking disc is prone to generating suction marks to influence the appearance of a product.

SUMMERY OF THE UTILITY MODEL

In view of the above, an object of the present invention is to provide a suction mark preventing sucker, which can form stable suction force and can not leave suction marks on the surface of a product.

The utility model discloses a reach the technical scheme that above-mentioned purpose adopted and be: the utility model provides a prevent inhaling trace sucking disc, includes a sucking disc body, and sets up in a buffer layer of this sucking disc body lower extreme, this internal cavity that link up from top to bottom that is formed with of sucking disc, wherein, evenly distributed has the absorption hole with this cavity intercommunication on this buffer layer.

As a further improvement of the utility model, the buffer layer is any one of non-woven fabric, sponge and non-woven fabric sponge cushion.

As a further improvement of the utility model, the non-woven fabric sponge cushion comprises a non-woven fabric sleeve and a sponge cushion arranged in the non-woven fabric sleeve.

As a further improvement of the utility model, the lower end of the sucker body is provided with an annular bulge protruding towards the periphery.

As a further improvement of the utility model, the buffer layer is adhered to the lower end of the sucker body through a hot melting process.

As a further improvement of the utility model, the buffer layer is adhered to the lower end of the sucker body through an adhesive layer.

As a further improvement of the utility model, the buffer layer is provided with a bag-covering structure matched with the lower end of the sucker body, and the lower end of the sucker body is sleeved with the bag-covering structure.

As a further improvement of the utility model, the thickness of the buffer layer below the cavity is 1-5mm.

As a further improvement of the utility model, the buffer layer and the thickness below the cavity are 2-3mm.

The utility model has the advantages that: the utility model discloses a prevent inhaling trace sucking disc through setting up the buffer layer at sucking disc body lower extreme, the adsorption affinity of sucking disc can be guaranteed to the adsorption hole on the buffer layer for the sucking disc has stable adsorption affinity, and simultaneously, the buffer layer has increased the area of sucking disc lower extreme with the product contact, plays the cushioning effect when the product is inhaled to the sucking disc, thereby effectually avoids the sucking disc to leave on the product and inhales the trace.

The above is an overview of the technical solution of the present invention, and the present invention is further explained with reference to the accompanying drawings and the detailed description below.

Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the intended purpose, the following detailed description of the embodiments of the present invention is provided in conjunction with the accompanying drawings and preferred embodiments.

Referring to fig. 1 to 7, a suction cup for preventing suction marks comprises a suction cup body 1 and a buffer layer 2 disposed at the lower end of the suction cup body 1, wherein a cavity 11 is formed in the suction cup body 1 and is vertically through, and suction holes 21 communicated with the cavity 11 are uniformly distributed on the buffer layer 2. Through setting up buffer layer 2 at 1 lower extreme of sucking disc body, the adsorption affinity of sucking disc can be guaranteed to the absorption hole 21 on the buffer layer 2 for the sucking disc has stable adsorption affinity, and simultaneously, buffer layer 2 has increased the area of sucking disc lower extreme with the product contact, plays the cushioning effect when the product is inhaled to the sucking disc, thereby effectually avoids the sucking disc to leave on the product and inhales the trace.

Specifically, the buffer layer 2 is any one of a non-woven fabric, a sponge, and a non-woven fabric sponge cushion 3. The non-woven fabrics and the sponge are soft in texture and good in air permeability, and have a good buffering effect while the adsorption force of the sucking disc can be guaranteed.

Specifically, as shown in fig. 3, the non-woven sponge pad 3 includes a non-woven fabric sleeve 31 and a sponge pad 32 disposed in the non-woven fabric sleeve 31. The non-woven fabrics is difficult damaged, and foam-rubber cushion intensity is great, makes non-woven fabrics foam-rubber cushion 3 through combining non-woven fabrics and sponge for the sucking disc is when adsorbing the product, and buffer layer 2 is difficult for taking place damaged and warp.

Specifically, the buffer layer 2 and the sucker body 1 can be combined in the following three ways:

(1) The buffer layer 2 is adhered to the lower end of the sucker body 1 through a hot melting process, as shown in fig. 1.

(2) The buffer layer 2 is adhered to the lower end of the sucker body 1 through an adhesive layer 4, as shown in fig. 5.

(3) The buffer layer 2 has a bag structure matched with the lower end of the sucker body 1 and is sleeved on the lower end of the sucker body 1, as shown in fig. 6 and 7.

Specifically, the thickness of the buffer layer 2 below the cavity 11 is 1-5mm, preferably, the thickness of the buffer layer 2 below the cavity 11 is 2-3mm, and in this embodiment, the thickness of the buffer layer 2 below the cavity 11 is 3mm. When the gas permeability of buffer layer 2 can be guaranteed at this thickness scope, buffering effect is good, has good and prevents inhaling the trace effect.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that other structures obtained by adopting the same or similar technical features as the above embodiments of the present invention are all in the present invention.
