Abstract
Description
Technical Field
[0001] The utility model relates to the field of oval printing machines, in particular to a connecting rod transmission mechanism for an oval printing machine. Background Art
[0002] During the working process of an oval printing machine, a carrier table is required to drive a printing placement plate to move along an oval track. The object to be printed is placed in the printing placement plate, and printing work is carried out at multiple stations along the track.
[0003] The printing placement plate needs to be fixed on the corresponding printing placement plate carrier table and move intermittently with the printing placement plate carrier table. In order to achieve the synchronous movement of all printing placement plate carrier tables, the connecting rod can be used for transmission. When driving one or more printing placement plate carrier tables to move, the connecting rod can be used to ensure the movement of all printing placement plate carrier tables. In order to adapt to the movement of the printing placement plate carrier table at the turning point of the oval track, the connecting rod is usually swingably fixed on the printing placement plate carrier table by a pin shaft.
[0004] In the prior art, due to processing and assembly accuracy problems, it cannot be guaranteed that the distance between every two printing placement plate carrier tables is uniform, and there are slight differences. During printing, the positioning mechanism is required at each station to accurately position the printing placement plate. However, the distance between the two adjacent front and rear printing placement plate carrier tables fixed by the connecting rod is not adjustable, and the positioning mechanisms at each station cannot change the positions of all printing placement plates simultaneously, so improvement is needed. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a connecting rod transmission mechanism for an oval printing machine, which is used for driving the printing placement plate carrier table and adapting to slight position changes during the positioning process.
[0006] To achieve the above object, the utility model adopts the following technical solutions:
[0007] A connecting rod transmission mechanism for an oval printing machine includes: a printing placement plate carrier table and a connecting rod. The printing placement plate carrier tables are distributed at intervals front and rear. The connecting rod is arranged between two adjacent front and rear printing placement plate carrier tables. Concave connection holes corresponding to one end of the connecting rod end are arranged on the printing placement plate carrier table. The connecting rod end is located above the corresponding connection hole. A conical hole concentric with the connection hole and pointing downward is arranged on the connecting rod. A taper sleeve is arranged in the conical hole. An oil storage groove is concavely arranged on the top surface of the taper sleeve. A screw penetrating downward through the connection hole is arranged in the oil storage groove. A spring located in the oil storage groove is arranged on the screw.
[0008] Wherein, a nut is arranged on the screw below the connection hole.
[0009] Among them, a roller mounting seat is further included. The roller mounting seat is arranged below the connecting hole and is fixed by a screw passing through it.
[0010] Among them, micro holes extending obliquely downward to the tapered hole are arranged in the oil storage tank.
[0011] Among them, the diameter of the micro holes is not greater than 1 mm.
[0012] Among them, a tapered surface corresponding to the tapered hole is arranged on the outer side of the tapered sleeve.
[0013] Among them, through holes corresponding to the screws are arranged at the bottom of the oil storage tank.

The tapered sleeve can be lifted and lowered to adapt to the left and right micro position changes of the front and rear adjacent two printing placement plate carriers during the positioning process, and the tapered sleeve is elastically pressed and reset by the spring during the movement process. The lubricating oil in the oil storage tank can also be sent to the tapered hole through the micro holes, reducing the friction between the tapered sleeve and the tapered hole.
