Description

Technical field:

[0001] The utility model relates to the technical field of corrugated paper box printing and packaging machinery and equipment, and more specifically to a wire feeding mechanism of an improved corrugated paperboard main nail head device. Background technology:

[0002] Corrugated cardboard is made into corrugated boxes through die-cutting, creasing, nailing or gluing. Corrugated boxes are the most widely used packaging products, and their usage has always been the first among various packaging products.

[0003] At present, the nail heads of the nailing machines in corrugated carton packaging equipment all use fixed intermittent nail heads. When nailing with this kind of nail head, the corrugated carton must stop, and after the nailing action is completed, it can be sent to the next predetermined position by the conveying mechanism to continue nailing. Therefore, this kind of nail head has a slow nailing speed and high power consumption, and gradually cannot meet the requirements of customers to improve production efficiency. Therefore, the Chinese patent application number 201621166213.2 for corrugated carton swinging non-stop nailing nail head adopts continuous nailing, which has good effect and high efficiency. However, there is no front guide device in the wire feeding mechanism of this nail head main machine. It only conveys the iron wire through the two rotating shafts to the wire guide spring tube for conveying. There is no guide device at the front, which makes it easy for it to be in an offset position before entering the two rotating shafts for clamping and conveying, causing friction with surrounding parts, which is easy to damage surrounding parts, affecting the normal use of the equipment, and even easy to cause related gears to jam.

[0004] Therefore, a wire feeding mechanism of a corrugated cardboard main nail head device with Chinese patent application number 202221438195.4 can ensure that the iron wire can enter the wire feeding channel for normal transportation through the guiding elongated block and the threading guide hanging ring. It has a good guiding effect, which makes it not easy to touch or cause friction and wear with other components, thereby ensuring the normal use of other components and the normal operation of the equipment.

[0005] However, this structure is installed at the top of the head shell, and during installation, when the head shell is turned upside down 180 degrees, it is at the bottom. This structure increases the height of the entire corrugated cardboard main nail head. When the installation position is insufficient, that is, the height of the installation position is limited, it cannot be installed, which limits its installation scope. Utility model content:

[0006] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide an improved wire feeding mechanism for a main nail head device of a corrugated cardboard, which places components such as a left fixing frame and a right fixing frame on the left and right sides of a head shell, thereby reducing the height of the entire head shell, increasing its installation range and improving its applicability.
