Baler pre-press assembly guide structure

Abstract

The invention discloses a guide structure for a prepressing head assembly of a press. The guide structure comprises an upper guide assembly, a lower guide assembly and guide rods, wherein the guide rods are correspondingly provided with two guide sleeve assemblies which lead an upper guide sleeve and a corresponding lower guide sleeve to be positioned; each upper guide sleeve and each lower guide sleeve respectively comprise a casing pipe, shaft seals mounted at the upper end and the lower end of the casing pipe and an embedded bushing embedded in the casing pipe and located between the upper shaft seal and the lower shaft seal, and each embedded bushing is provided with a guide face used for guiding the corresponding guide rod. The guide structure for the prepressing head assembly of the press has the characteristics of roller high-speed guiding and guide sleeve smooth guiding.

Description

technical field [0001] The invention relates to a guiding structure of a pre-pressing head assembly of a baler. Background technique [0002] In the existing domestic cotton processing machinery technical field, the cotton baler basically realizes mechanization, and the cotton is processed into a prescribed bag type by the cotton baler. Generally speaking, the cotton baler consists of two parts: main pressure and pre-compression. The pre-compression part is driven by the pre-compression cylinder to step on the cotton in the up and down direction. The pre-compression head assembly is guided by the guide rod assembly installed on both sides. Long, fast, uneven force and prone to vibration. [0003] The guide structure of the existing pre-pressing head assembly is configured as a structure in which the guide rod assembly and the guide roller assembly cooperate. Generally speaking, two sets of guide rollers are configured for the guide rod, and each set of guide rollers is equi...

In addition, as mentioned above, in high-speed guiding applications, the heat generation is very large, resulting in a relatively high temperature of the friction joint surface. When the friction is poor, the temperature of the friction joint surface can even be as high as 200 degrees Celsius. Under this temperature condition, the oil film cannot be formed. Or the lubricating oil is aging and will fail in a short time

[0008] In order to avoid grease from contaminating the cotton, the inventors tried to use copper guide sleeves. However, the friction of copper guide sleeves in high-speed applications is very severe, and copper guide sleeves will fail in a short period of time.
