Description
Technical field
The utility model relates to the photovoltaic field, particularly a kind of stock that is used for printing machine.In addition, the utility model also relates to a kind of printing machine that comprises above-mentioned stock.
Background technology
When presswork is carried out in the photovoltaic field, mainly utilize stock to receive printing ink or adsorb colorant and present various picture and text, therefore, the performance of stock and operating efficiency have directly influenced the output and the quality of printing machine.
Stock is one of printing four key elements, is mainly used in the silicon chip that carries printing in process of production, and silicon chip is positioned so that carry out presswork.End at stock is provided with the connecting rod 1 that can rotate in a circumferential direction, and please refer to Fig. 1, and connecting rod 1 is long tube straight tube; Be connected with locating shaft 3 respectively at its two ends; Locating shaft 3 is generally and adopts stainless steel to process, and stepped, its small end inserts connecting rod 1 inside; Connecting rod 1 is realized rotating in a circumferential direction under the support of locating shaft 3, and the diameter of the big end of locating shaft 3 is identical substantially with the external diameter of connecting rod 1; In order to reduce the wearing and tearing between connecting rod 1 and the locating shaft 3, between connecting rod 1 and locating shaft 3, also be provided with stair-stepping connecting ring 2, the small end of locating shaft 3 loads insertion connecting rod 1 inside at the cover of connecting ring 2; This connecting ring 2 is generally the plastics connecting ring; The external diameter of its big end is identical substantially with the diameter of the big end of locating shaft 3, and the external diameter of its small end is more slightly smaller than the internal diameter of connecting rod 1, and the internal diameter of connecting ring 2 is more slightly larger than the diameter of the small end of locating shaft 3; Its length is identical substantially with the length of the small end of locating shaft 3; To make things convenient for the installation of locating shaft 3, like this, all do not have directly to contact between locating shaft 3 and the connecting rod 1.
Directly carry out presswork in the insertion connecting rod 1 with respect to locating shaft 3, between locating shaft 3 and connecting rod 1, plastics connecting ring 2 is set, reduced the wearing and tearing when locating shaft directly contacts with connecting rod 1; But the friction between each parts still is sliding friction, and its coefficient of friction is relatively large, and the wearing and tearing of the connecting ring 2 that the employing plastic material processes are the most serious; Cause the abrasion deformation of connecting ring 2 after long-term the use easily, cause fixing generation of connecting rod 1 rotary centerline in rotation process to be squinted, the wearing and tearing of connecting ring 2 are serious more; The rotation error of connecting rod 1 is big more; The resistance that its rotation receives is big more, quickens the wearing and tearing between each parts, and then the direction that platform paper transmits is produced bigger error; Also can cause the loose sheet fragment that gets rid of of platform paper, the output and the quality of influence printing; After wearing and tearing acquire a certain degree, very likely cause phenomenons such as connecting ring 2 slide fasteners, the fracture of platform paper, have a strong impact on normal presswork; In addition, in connecting rod 1 rotation process, also can produce the higher friction noise, influence the working environment in workshop.
Therefore, if reduce the wearing and tearing between connecting rod and the locating shaft, and then the output and the quality of raising printing are those skilled in the art's technical issues that need to address.
The utility model content
The purpose of the utility model provides a kind of stock that is used for printing machine, and this stock can significantly reduce wearing and tearing, improves the output and the quality of printing machine.Another purpose of the utility model provides a kind of printing machine that comprises above-mentioned stock.
For solving the problems of the technologies described above, the utility model provides a kind of stock that is used for printing machine, comprises the connecting rod of hollow and the locating shaft that is installed on said connecting rod two ends, and said locating shaft is installed in said connecting rod inside through bearing.
Preferably, said bearing is a stainless steel bearing.
Preferably, further be set with the axle sleeve that is positioned at said bearing both sides on the said locating shaft.
Preferably, said locating shaft is fixed on the stock through screw.
Preferably, said connecting rod is the aluminium connecting rod.
The utility model also provides a kind of printing machine, comprises above-mentioned any described stock.
Preferably, said printing machine is a screen process press.
The stock that the utility model provided; Its locating shaft passes through bearing hinge joint in the inside at the two ends of connecting rod; Friction between connecting rod and the locating shaft changes rolling friction into by sliding friction of the prior art like this; As everyone knows, coefficient of rolling friction is much smaller than the coefficient of sliding friction under identical material; Therefore; Wearing and tearing when the stock that the utility model provided effectively reduces connecting rod and locating shaft operation; Improved the service life of connecting rod and locating shaft; And the irregular phenomenon of its rotary centerline can not appear in connecting rod in rotation process, thereby has effectively guaranteed the transmission angle of platform paper, helps improving the output and the quality of printing.In addition, connecting rod noise can not occur rotating when under the support of bearing, rotating, and helps to improve the working environment in workshop.
In a kind of preferably embodiment; Both sides at bearing also are provided with axle sleeve; Axial location to bearing carries out reliable localization, has guaranteed can not occur at connecting rod rotation process middle (center) bearing the phenomenon of slippage effectively, helps to reduce the number of times of platform paper fracture; Increase the service life of platform paper and connecting rod, reduce the cost of printing.
