Description

A kind ofly be used to prevent that the PVC non-drying glue from tearing the device that pastes distortion

Technical field

The utility model relates to a kind of PVC of being used for non-drying glue and pastes the frock of using, and is specifically related to a kind ofly be used to prevent that the PVC non-drying glue from tearing the device that pastes distortion, uses in PVC non-drying glue and sheet metal component paste operation process usually.

Background technology

Non-drying glue also is the self-adhesive label material, is to be lining with paper, film or special material, and the back side scribbles adhesion agent, to be coated with a kind of composite material that the silicon protection sheet is a base stock.Use plane materiel: model wood free paper, art paper art paper (shading/minute surface), transparent PVC, static PVC, polyester PET, U.S. line paper, sandwich copperplate, heat sensitive paper etc.; Use base stock: white, indigo plant, yellow Ge Laxin paper glassine (or garlic skin paper onion), craft paper, polyester PET, art paper, poly-vinyl polyethylene; Use the glue type: general ultra sticking type, general strong sticking type, the sticking by force type of chilled food, general type, the fiber opened are again opened type again.

In can manufacturing, on sheet metal component, paste PVC FOAM (flexible foamed of polyvinylchloride sponge) sometimes, be that a kind of plane materiel is flexible foamed of a PVC sponge; The plane materiel back side is common two-sided glued membrane; During use, base stock is opened, be affixed on the panel beating surface through adhesion agent.Yet, in actual mechanical process, because PVC FOAM plane materiel is thinner; Be merely about 3mm, in the process of manual tearing, be prone to produce tensile deformation, when causing affixing on the product; Plane materiel has exceeded the edge of product, thereby produces scrap, needs to paste again; Improve productive costs on the one hand, influenced work efficiency on the other hand.

Summary of the invention

The utility model purpose provides and a kind ofly is used to prevent that the PVC non-drying glue from tearing the device that pastes distortion, through using this device, is convenient to the stickup of non-drying glue, reduces the generation of scrap, enhances productivity, and reduces production costs simultaneously.

For achieving the above object; The technical scheme that the utility model adopts is: a kind ofly be used to prevent that the PVC non-drying glue from tearing the device that pastes distortion; Comprise and tool and the vacuum device of waiting to tear subsides PVC non-drying glue size coupling; Said tool is by box body, the lid that cooperates with the box body open top and be arranged at the service platform on the lid; Be provided with positioning groove between said service platform edge and the said box body edge, be positioned at said positioning groove on the said lid and be provided with a plurality of breather holes that communicate with said box body, said lid is provided with the locating dowel pin perpendicular to the lid surface arrangement; This locating dowel pin is waited to tear the knock hole that pastes on the PVC non-drying glue and is matched with said, said service platform surface with wait that tearing subsides PVC non-drying glue facestock surface cooperates; Said box body is provided with bleeding point, and the communication port of said vacuum device is communicated with this bleeding point.

In the technique scheme; Said vacuum device comprises vacuum generator, connecting line and is arranged at the switch on the connecting line; Wherein, the outlet of said vacuum generator is connected with said bleeding point, and the inlet of said vacuum generator is connected with source of the gas through said connecting line.

In the preceding text, said vacuum generator adopts prior art, and its principle of work is to utilize jet pipe high speed jet pressurized air; Form jet at nozzle exit; Generation is entrainmented mobile, under the effect of entrainmenting, makes the nozzle exit ambient air constantly walked by suction; Make the interior differential pressure of adsorbent chamber to barometric pressure, form the certain vacuum degree.In the utility model, utilize vacuum generator to vacuumizing in the box body, make to lay to place the PVC non-drying glue on the service platform to be adsorbed on the service platform; Tear PVC non-drying glue base stock this moment again, because the PVC non-drying glue has been adsorbed the location, cooperates the location of locating dowel pin and positioning groove; Thereby effectively overcome the lengthening deformation that produces when tearing base stock; Then the panel beating bedding is got on,, accomplish and fit by the locating dowel pin location.At last, off switch breaks off source of the gas, cancels vacuum adsorption force, takes off finished product.

Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:

1, the utility model is through vacuumizing tool, and air-flow makes and waits that the PVC non-drying glue that tears subsides is adsorbed on the service platform on tool surface in breather hole is drawn into box body; Tear PVC non-drying glue base stock this moment again, is positioned by PVC non-drying glue plane materiel, therefore; Tearing power can facestock not produce elastic deformation, so panel beating is pasted up again, and finished product machines; Close vacuum device, take off finished product; So with in the past manual tear to paste compared, paste more conveniently, and yield rate height reduces production costs;

2, the utility model is simple in structure, is easy to realize, is applicable to that the thin non-drying glue of plane materiel tears subsides.
