Abstract
The utility model relates to a gripper pad structure for a printing press, which is especially suitable for a gripper pad of a piece of gripper paper of a flat and straightened paper printing press. The utility model is characterized in that the surface of a base body 1 made of rigid materials is provided with a groove 4; elastic materials 2 are filled in the groove to form a plane made of rigid materials and elastic materials; the plane is engaged with paper gripping teeth. The utility model has the advantages of stable paper holding force, no displacement between the paper grippingteeth and the gripper pad and no damage to paper. The quality of printing articles is good. The elastic materials can not generate the dropping off phenomenon.
Description
The utility model relates to a kind of bite-block structure of printing machine, and what be specially adapted to sheet offset printing of paper machine stings paper sound of baby talk pad.
In printing machine when work, match and hold the transmission that paper paper carries out paper in the month by stinging paper tooth and bite-block.When paper is transmitted, do not allow that power is not enough to be subjected to displacement stinging between paper tooth and bite-block because of holding in the month, otherwise can have a strong impact on printing quality.Simultaneously, do not allow because of holding the excessive paper sheet break that makes of power in the month yet.In order to reach above-mentioned requirements, in some printing machines, adopted bite-block as shown in Figure 1, on the matrix 1 of rigid material, covered one deck elastomeric material 2.This structure since rigidity sting paper tooth and the surperficial interlock mutually of flexible bite-block, can not guarantee that it holds the stability of paper power in the month, and its clad material peels off easily.Also has the bite-block structure that adopts as shown in Figure 2, it is to process the groove 3 that both direction intersects on the surface of rigid matrix 1, in groove, inject elastomeric material, though this structure has solved the problem of holding paper power in the month, but because of the elastomeric material in its groove links to each other, therefore, in case the flexible material in edge does not cement, can cause peeling off of whole injected plastics material layer, influence product (printed matter) quality.
The purpose of this utility model is to provide a kind of paper power of holding in the month to stablize exactly, is stinging non-displacement between paper tooth and bite-block, again not because of holding the excessive bite-block structure that causes paper sheet break, influences print quality of power in the month.
The purpose of this utility model is achieved in that a kind of printing machine bite-block structure, be specially adapted to the sheet flatting machine offset press and sting paper sound of baby talk pad, it is characterized in that on the surface of the matrix 1 of rigid material, processing groove 4, in groove, insert elastomeric material 2, form that rigidity and elastomeric material form with the plane of stinging the interlock of paper tooth.
The purpose of this utility model can also further be realized by following technical measures.
Aforesaid bite-block structure, the elastomeric material of inserting in the groove 42 is Polyurethane.
Elastomeric material in the utility model is to be embedded in fully in the matrix 1 of rigid material; be equivalent to fill elastomeric material in the rigid backbone; elastomeric material has guaranteed required frictional force; rigid material has then protected elastomeric material to be unlikely the generation permanent deformation, has guaranteed to hold in the month the stability of paper power simultaneously.Elastomeric material can be fixed in the rigid matrix well in addition, can not produce peeling phenomenon.So the printing machine paper behind employing this programme does not have breakage, print quality height.
Below in conjunction with Figure of description and embodiment, the utility model is further described.
One of grippers bite-block structure that Fig. 1 adopts for existing printing machine.Wherein 1 is the rigid matrix of bite-block, and 2 is one deck elastomeric material that covers on the surface of rigid matrix 1.
Fig. 2 is the top view of Fig. 1.
The another kind of bite-block structure that Fig. 3 is adopted for existing printing machine, it is to process the groove 3 that both direction intersects on the surface of rigid material matrix 1, has injected elastomeric material 2 simultaneously in groove 3.
Fig. 4 is the top view of Fig. 3.
Fig. 5 is the bite-block structure of printing machine grippers of the present utility model.
Fig. 6 is the top view of Fig. 5.
In the embodiment shown in Fig. 5 and 6: on the surface of rigid material matrix 1, be processed with groove 4, in groove, insert elastomeric material 2, as Polyurethane etc.This plane of being made up of rigidity and elastomeric material is exactly and the occlusal surface of stinging the paper tooth surface of paper contact just.The paper tooth of stinging of this surface and rigid material matches when biting paper; because of elastic surface can produce bigger frictional force; thereby paper can be held in the month firmly; again because of the partially rigid of bite-block surface with sting the paper tooth and contact; protected the not frequent interlock of reason of elastic surface, and permanent deformation has taken place, simultaneously; guaranteed to hold in the month the stability of paper power again, thereby the print quality height.In addition,,, can not produce peeling phenomenon, prolong the service life of equipment so elastomeric material is fixed because elastomeric material is to be filled in the groove of rigid matrix.
Claims (2)
1, a kind of bite-block structure of printing machine, what be specially adapted to sheet offset printing of paper machine stings paper sound of baby talk pad, it is characterized in that on the surface of rigid material matrix (1), processing groove (4), in groove, insert elastomeric material (2), form that rigidity and elastomeric material form with the plane of stinging the interlock of paper tooth.
2, bite-block structure according to claim 1, the elastomeric material (2) that it is characterized in that inserting in the groove (4) is Polyurethane.
