Fixed printing slotting die-cutting machine provided with spiral bevel gear drive means

Abstract

The present invention discloses a fixed printing slotting die-cutting machine provided with a spiral bevel gear drive means, comprising a plurality of sealed gear cases each of which is mounted on the external side of each unit wallboard, inside the gear case, one pair or a plurality of pairs of spiral bevel gears constituting drive pairs, two drive pairs being connected via a cross coupler among the gear cases, thus forming a drive means. The drive means is characterized in that: the drive means is composed of a pair of spiral bevel gears which are in an engagement relationship, the pair of spiral bevel gears being respectively mounted at the top ends of two drive shafts which are perpendicular to each other, the drive shaft being mounted on a bearing pedestal of a gear case via a bearing, the other end of one bearing shaft being provided with a gear which engages with a main drive gear of each unit and the other end of the other bearing shaft being coupled to a cross coupler, the cross coupler being also coupled to a drive shaft of a next unit gear case so as to transmit drive power. The method enlarges the power source transmission span between two units and reduces multiple gear transmission steps. At the same time, the high accuracy of the spiral bevel gear enables a high synchronization among each unit.

Description

technical field [0001] The invention relates to a packaging machine, in particular to a fixed printing slotting die-cutting machine, which is provided with a spiral bevel gear transmission mechanism. Background technique [0002] Stationary printing slotting die-cutting machine is a widely used packaging machinery, its main structure is as follows figure 1 As shown, it includes a paper feeding unit 11, a plurality of printing units 12, a slotting unit 13 and a die-cutting unit 14, and each unit works in a unified and coordinated manner under the action of the power equipment and the transmission mechanism to jointly complete the paper feeding, printing, and printing of the cardboard. Grooving and die cutting. It is equipped with a spiral bevel gear transmission mechanism, including a sealed gearbox installed on the outside of each unit wall panel. There are one or more pairs of spiral bevel gears in the gearbox to form a transmission pair. There is a cross between the gearb...

Problems solved by technology

[0003] The main structure of the transmission system of the existing fixed printing slotting die-cutting machine is as follows: figure 2 as shown, figure 2 It includes a series of transmission gears installed outside the wall panel on one side of the fixed printing slotting die-cutting machine. Starting from the driving wheel 21, the power is transmitted to two sets of paper feed wheels 22 through the bridge wheels 211 and 212 respectively, and then through the The bridge wheel 221 is passed to the printing roller gear 23, and then the power is transmitted to the printing roller gear 24 of the next unit through the bridge wheel 231, gear 232, gear 233, gear 234, gear 235 and gear 236, and the same method is used , through a series of bridge wheels and gears, the power is transmitted to the transmission gears of the slotting unit and the die-cutting unit. Due to the low precision of the gears and the large gap error between the gears, it will directly cause the main transmission gears of each unit to be inconsistent. , affecting the accuracy of printing, slotting and die-cutting

[0004] With the advancement of technology, the quality of products is required to be higher, and the existing fixed printing slotting die-cutting machine is no longer suitable for this demand, and there are deviations in the pace of each transmission system. The cutting effect is also worse, seriously affecting the quality of carton printing

In order to improve the printing quality, it is necessary to provide a solution that can be solved on the traditional fixed printing slotting die-cutting machine. There is already a method of using servo motors instead of transmission gears, but the cost of installing servo motors is very expensive, which greatly increases The cost of equipment has been reduced, which has made a large number of small and medium-sized carton companies unbearable. It is necessary to find a method that does not increase the burden, but also prints high-quality products quickly, efficiently and economically, so as to meet the needs of producing different carton products and is suitable for the market. development requirements
