The utility model provides a paper tooth row location device, including a paper tooth row, which is characterized in a groove in the end of the paper tooth row, and a positioning block is provided in the groove. The teeth sides are separately arranged on both sides of the positioning block, and the teeth sides are separated from both sides of the grooves contacting the two sides of the positioning block, and the positioning block and the groove are passed through the groove. The tooth edges are meshed with each other, and the outer ends of the positioning blocks extend outward and are matched with the fixed contact pieces on the printing machine. When the outer end of the positioning block is worn and the extension needs to be adjusted, a tooth or a number of teeth are moved outward from the outer end of the positioning block, and the position adjustment can be carried out quickly and accurately, and the position block can be displaced and the positioning function is strengthened through the intermeshing teeth edge preventing the force produced by the collision. It can not only make the position adjustment of the location block as accurate and fast as the original bolt location block, but also can fundamentally solve the problem that the wear and deformation of the high speed collision can not be adjusted, and the service life of the paper tooth row is prolonged.

印刷机叼纸牙排定位装置
本技术涉及一种定位装置,特别是一种印刷机用方便快速调节的叼纸牙排定位装置,属于印刷机械设计制造
技术介绍
叼纸牙排是印刷机在印刷时叼住并移动纸张的装置,通过叼纸牙排的移动来确保纸张准确地处于印刷位置上,以防止印偏而造成废品。现有的叼纸牙排端部设有螺孔,螺孔中设置螺栓,通过螺栓的伸出与缩回调节,使螺栓能够与机架上的固定触片相碰撞,一旦碰撞即停止叼纸牙排的移动,从而完成叼纸牙排的定位。但由于定位螺栓在高速碰撞中极易因冲击力而导致螺纹极易被磨损、变形,致使螺栓因无法转动而失去伸缩调节作用,为此不得不更换整个叼纸牙排。这样必然要增加维修成本及时间,影响正常生产。因此有必要对现有技术加以改进。
技术实现思路
为解决现有叼纸牙排使用定位螺栓而带来螺纹易被磨损、变形,致使螺栓因无法转动而失去伸缩调节作用,进而必须更换整个叼纸牙排,造成成本增加、影响工作效率等问题,本技术提供一种印刷机叼纸牙排定位装置。本技术通过下列技术方案完成:一种印刷机叼纸牙排定位装置,包括叼纸牙排,其特征在于叼纸牙排端部设有凹槽,凹槽中设有定位块,其中,所述定位块两侧分别设有齿 ...
