Nailing machine of corrugated case

Abstract

The invention carton stapler for corrugated cases and belongs to the field of corrugated case manufacturing equipment. The carton stapler adopts a paper conveying mechanism which uses a hexagonal steel type transmission shaft to drive two small belts (1). A driving roller (2) and a driven roller (3) one each side of each small belt (1) are connected together through a small wall plate (17) on thesame side, and each small belt (1) is also provided with a complete manual adjustment mechanism which adjusts axial displacement by using a threaded rod threaded rod shaft as well as an array roll type transverse positioning mechanism and a paper pressing belt (36) type paper pressing mechanism with a small roll (38), wherein the manual adjustment mechanism, the array roll type transverse positioning mechanism and the paper pressing belt (36) type paper pressing mechanism are all connected with the small wall plate (17) the transverse position of which can be adjusted. The carton stapler alsoadopts an automatic head nailing device which has a light controlled automatic system and is matched with the continuous paper conveying device. The transverse position of the automatic head nailing device is adjustable, the vertical position of a nail head holder (57) and the size of the paper pressure are adjustable, and a nail tongue (64) of a belt base plate (55) is changeable. The rollers can be changed easily and the transverse positions of the rollers can be adjusted conveniently, the friction is small, and the paper pressure is adjustable in terms of size. The carton stapler can not damage the surface of corrugaled board and the patterns on the surface of the corrugaled board, achieves excellent nailing quality, high efficiency and low energy consumption, and is convenient in adjustment and maintenance and is suitable to nail corrugaled boards with different thicknesses.

Problems solved by technology

[0002] In the production of corrugated cardboard boxes, the final process is to nail the corrugated boards. In the prior art, there are two methods of nailing the corrugated boards: the first is to use corrugated boards after the corrugated boards are folded by the folding device. The nail box machine is used for nailing, and its paper feeding mechanism is as follows: a large belt is installed on the main and driven rollers, and the two rollers are respectively installed on the corresponding driving and driven circular shafts through axial long keys, and there is a belt tensioner. Its laterally positioned side gauges are adjustable plate gauges on both sides, and its paper pressing mechanism is a rotary roller direct pressure type set at horizontal intervals; the disadvantage is that it is troublesome to replace the active and driven rollers, and its The axial position on the circular shaft is not easy to adjust, and the long key must be loosened, which is very inconvenient, and the long keyway and axial long key of the through-shaft type are not easy to process. In addition, a large belt transports paper and has a large momentum. , high energy consumption; and the board type regulation, the friction generated by the corners of the corrugated cardboard to be transported is large, not only the corrugated cardboard is easily damaged, but also the paper feeding resistance is large; The pressure of corrugated cardboard lacks flexibility, stability and continuity. Therefore, it is easy to crush the corrugated cardboard to be conveyed, especially the printed graphics on the surface of the corrugated cardboard to be conveyed. The size of the pressure is not easy to adjust, so it is easy to cause problems in the subsequent nailing, thereby affecting the quality and production efficiency of the nailing; in addition, the lateral position adjustment mechanism in the nail head device is simply a screw locking type, It is very inconvenient, but the vertical position of the nail head seat cannot be adjusted, and the nail tongue cannot be replaced. The nail loading machine is manually opened and stopped, which is inconvenient in application

The second is that the corrugated cardboard that has been die-cut and indented is not folded by a folding device, but is directly nailed manually. The nail head device is a DX1020 series nailing machine installed on the frame. The foot pedal controls the electric switch and staples the corrugated cardboard one by one, which consumes a lot of manpower and man-hours, the production efficiency is low, and the quality of the staples is not good, especially it is difficult to match with the continuous paper feeding mechanism, but this method is still widely used.
