Description

Double-nail-head box nailing machine transmission mechanism capable of rapidly switching synchronous and separation modes Technical Field The application relates to the technical field of carton stapling equipment, in particular to a transmission mechanism of a double-nail-head carton stapler, which can rapidly switch between synchronous and separation modes. Background The double-sheet carton stapler is key equipment for the subsequent process of carton forming, and the carton cover is closed by nailing. In order to improve the production efficiency and the adaptability, modern carton nailing machines are generally provided with an upper nail head and a lower nail head, and can simultaneously carry out nailing operation on an upper cover and a lower cover of a carton. However, in actual production, the need for only stapling a single-sided lid (i.e., a single-piece staple box) is often encountered. In the prior art, the mode switching for realizing the synchronization and separation of the double-nail heads is realized by a complex electric control system and an electromagnetic clutch, so that the cost is high and the maintenance is complex, and the mode switching is realized by manually disassembling a transmission connecting piece (such as a belt and a coupling), so that the operation is tedious and time-consuming, and the production efficiency is seriously influenced. Therefore, there is a strong need for a mechanical transmission solution that is simple in construction, low in cost, and capable of achieving fast mode switching. Disclosure of Invention Aiming at the defects of the prior art, the application provides a transmission mechanism of a double-nail-head box nailing machine, which can rapidly switch between synchronous and separation modes. The application provides a transmission mechanism of a double-nail-head box nailing machine capable of rapidly switching between synchronous and separation modes, which adopts the following technical scheme: a kind of double-pin-head carton stapler drive mechanism that can switch over and synchronize and separate the mode fast, including the carton stapler; The upper nail head mechanism and the lower nail head mechanism are arranged on the box nailing machine, the upper nail head mechanism and the lower nail head mechanism are both connected with a transmission mechanism, and the transmission mechanism comprises: The upper nail head eccentric wheel is coaxially and fixedly connected with an input shaft of the upper nail head mechanism; the lower pin head eccentric wheel is coaxially and fixedly connected with an input shaft of the lower pin head mechanism; The connecting assembly is rotatably arranged with the eccentric shaft of the upper nail head eccentric wheel, and the connecting assembly is rotatably arranged with the eccentric shaft of the lower nail head eccentric wheel. The power transmission and the power disconnection of the upper nail head mechanism and the lower nail head mechanism are realized through the connecting component, so that the synchronous and separated working modes of the double-nail head box nailing machine are realized, and the mechanical transmission scheme which has a simple structure and low cost and can realize rapid mode switching is realized. Optionally, the eccentric shaft of the upper pin head eccentric wheel is equal to the eccentric distance of the eccentric shaft of the lower pin head eccentric wheel. The design of the equal eccentricity enables the pushing-out/withdrawing distance, the moving speed and the moving amplitude of the nailing executing component to be identical under the synchronous mode of the upper and lower nail head mechanisms, ensures the nailing depth of the upper and lower covers of the carton and the forming effect of the nail feet to be highly consistent, avoids the conditions of too deep nailing of the upper cover and too shallow nailing of the lower cover or vice versa, ensures the technological consistency of synchronous nailing from the structural source, and improves the nailing quality and the aesthetic property of the finished carton. Optionally, the connection assembly includes: the inner ring of the first bearing is fixedly arranged on the eccentric shaft of the upper nail head eccentric wheel; The first connecting rod is connected with the outer ring of the first bearing in a detachable and fixed way at one end of the first connecting rod; The inner ring of the second bearing is fixedly arranged on the eccentric shaft of the lower pin head eccentric wheel; One end of the second connecting rod is detachably and fixedly connected with the outer ring of the second bearing; The connecting rod is of a structure in which two sections of round rods are coaxially and rotatably installed, one end of the connecting rod is in threaded connection with one end of the first connecting rod, which is far away from the upper nail head eccentric wheel, and the other end of the connecting rod is in threaded
