Technical Field

[0001] The utility model relates to the technical field of mechanical disassembly and assembly, in particular to a protective maintenance mechanism for a roller shaft of a puffing section. Background Art

[0002] Roller shafts are widely used in drafting, combing, conveying and other mechanisms. According to their functions, they are divided into drafting rollers, feeding rollers, pressing rollers, working rollers, etc.

[0003] The existing bottom roller of the puffing section of the burning machine has 11 roller shafts, and the 11 roller shafts are installed on the same panel bracket. When one of the roller shafts is bent and deformed, it needs to be maintained and replaced;

[0004] Because the roller shaft is installed inside and there are limiting structures on the upper and lower surfaces, the roller shaft cannot be removed from the vertical plane, resulting in the need to disassemble the 11 roller shafts on the panel bracket as a whole and pull out the panel bracket before taking out one of the roller shafts, resulting in low efficiency and high working hours.

[0005] For this reason, we propose a puffing section roller shaft protection and maintenance mechanism to solve the existing problems. Utility Model Content

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a puffing section roller shaft protection and maintenance mechanism, comprising a mounting head, a panel bracket, a roller shaft and a bearing seat, the panel bracket is provided with preset holes at equal intervals, one end of the roller shaft is rotatably provided with a mounting head, the mounting head is inserted into the preset hole, the diameter of the mounting head is matched with the inner diameter of the preset hole, and the inner diameter of the preset hole is larger than the diameter of the roller shaft, the other end of the roller shaft is rotatably inserted into the bearing seat, and the bearing seat is fixed on the panel bracket.

[0008] Preferably, a base plate is welded to one end of the mounting head, and the base plate is closely attached to the outer wall of the panel bracket;

[0009] The base plate is provided with mounting holes at equal intervals, the mounting holes are movably plugged with mounting nails, and one end of the mounting nail is threadedly mounted inside the panel bracket.

[0010] Preferably, a connecting head is welded at the other end of the mounting head;

[0011] A reserved groove is provided on the end surface of the connector, and a bearing body is embedded and installed in the reserved groove;

[0012] The two ends of the roller shaft are symmetrically welded with shaft heads, one of the shaft heads is inserted and positioned in the inner ring of the bearing body, and the other shaft head is inserted in the bearing seat.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. When the roller shaft of the puffing section roller shaft protection and maintenance mechanism of the utility model needs to be replaced, the mounting nails on the base plate can be removed, and a pulling force is applied to the mounting head to pull the roller shaft rod out of the preset hole as a whole. When replacing a new roller shaft rod, it is inserted into the preset hole so that one end of the roller shaft rod is inserted into the opposite bearing seat, and then the base plate is fixed on the panel bracket, and the roller shaft rod can be rotatably installed on the panel bracket. Under the premise that the roller shaft rod is subjected to stable force, the utility model can perform disassembly, assembly and replacement operations on a single roller shaft rod in the horizontal direction, which greatly improves the disassembly and assembly efficiency of the roller shaft rod, has an effective protection and maintenance effect, and reduces working hours.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] like Figure 1-Figure 4As shown, the utility model proposes a protective maintenance mechanism for the roller shaft of the expanding section, comprising:

[0024] The mounting head 3, the panel bracket 5, the roller shaft 8 and the bearing seat 12, the panel bracket 5 is provided with preset holes 1 at equal intervals, one end of the roller shaft 8 is rotatably provided with a mounting head 3, the mounting head 3 is inserted into the preset hole 1, the diameter of the mounting head 3 is matched with the inner diameter of the preset hole 1, and the inner diameter of the preset hole 1 is larger than the diameter of the roller shaft 8, the other end of the roller shaft 8 is rotatably inserted into the bearing seat 12, and the bearing seat 12 is fixed on the panel bracket 5.

[0025] Based on Example 1:

[0026] By comparing the diameters and inner diameters of various structures, when the roller shaft needs to be replaced, the mounting nails 4 on the base plate 2 can be removed, and a pulling force can be applied to the mounting head 3 to pull the roller shaft 8 out of the preset hole 1 as a whole. When replacing a new roller shaft 8, it is inserted into the preset hole 1 so that one end of the roller shaft 8 is inserted into the opposite bearing seat 12, and then the base plate 2 is fixed on the panel bracket 5, and the roller shaft 8 can be rotatably installed on the panel bracket 5. Under the premise that the roller shaft 8 is subjected to stable force, a single roller shaft 8 can be disassembled, assembled and replaced in the horizontal direction, which greatly improves the disassembly and assembly efficiency of the roller shaft 8, plays an effective protection and maintenance effect, and reduces working hours.
