The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0028] Example 1:

[0029] This embodiment provides a shaft protection kit. This shaft protection kit is used to protect shaft A01, such as... Figures 1-2 As shown, it can protect the exposed part of the shaft A01 extending from the main body A02 from impact damage, and prevent waste materials from clogging or passing through the gap between the shaft A01 and the first through hole A02-1, thus preventing damage to the shaft A01. Figures 1-2 As shown, one end of the shaft A01 is disposed inside the main body device A02, and the other end extends out of the main body device A02 through the first through hole A02-1 on the main body device A02 and is fixedly connected to the component A03 to be driven.

[0030] In this embodiment, the shaft protection kit mainly comprises two parts: a limiting plate 1 and a protective sleeve 2. For example... Figure 1As shown, when the shaft protection sleeve is installed on the main device A02, the position of each component, wherein the limiting plate 1 is arranged on the outer wall of the main device A02, and the protection sleeve 2 is sleeved on the outer wall of the shaft A01. Further, as shown Figures 2-4 As shown, the limiting plate 1 is provided with a second through hole 101 and a limiting groove 102, and the protection sleeve 2 is formed with a first positioning end 201 at one end and a protection end 202 at the other end; when the shaft protection sleeve is installed on the main device A02, the second through hole 101 is in communication with the first through hole A02-1 on the main device A02, which can allow the shaft A01 to pass through and extend out of the main device A02; the first positioning end 201 is in contact with the to-be-driven component A03, and the protection end 202 is embedded in the limiting groove 102. For example, as shown in the arrangement form in Figure 2 In this structure, the to-be-driven component A03 and the limiting plate 1 jointly limit the movement range of the protection sleeve 2 in the left-right direction, so that the protection cavity of the protection sleeve 2 can always accommodate the exposed part of the shaft A01 extending out of the main device A02 and the gap between the shaft A01 and the second through hole 101. In this structure, the second through hole 101 is located outside the main device A02 compared with the first through hole A02-1, so that the gap between the shaft A01 and the second through hole 101 can be protected by not entering the waste materials. At the same time, the wall surface of the limiting groove 102 is in contact with the inner wall surface of the shaft protection sleeve, which also avoids the sinking of the shaft protection sleeve to contact the shaft A01, causing mutual friction and wear between them.

[0031] In this structure, although the relative position of the protection sleeve 2 is fixed by the cooperation of the to-be-driven component A03 and the limiting plate 1, which makes the to-be-driven component A03 rotate and drive the protection sleeve 2 to rotate relative to the limiting plate 1, thereby causing wear between them, regular maintenance or replacement of parts is required, but the protection sleeve realizes the function of protecting the shaft A01 and the shaft driving device with higher protection value, and overall reduces the expenditure of later maintenance and repair of the equipment with the shaft A01.

[0032] Preferably, the shaft protection sleeve further comprises a supporting element 3. The supporting element 3 mainly serves to support and hold the shaft A01, avoiding direct contact of the shaft A01 with the inner wall of the first through hole A02-1 and the inner wall of the protection sleeve 2 when subjected to external force, thereby causing wear. As shown, Figure 5 As shown, it mainly comprises an outer ring block 301 and an inner ring block 302, as shown Figure 2As shown, when the shaft protection kit is installed on the main device A02, the supporting element 3 is arranged between the first through hole A02-1 and the shaft body A01; the outer ring block 301 is connected with the main device A02, and the inner wall of the inner ring block 302 is in close contact with the shaft body A01, so that the shaft body A01 can drive the inner ring block 302 to rotate axially relative to the outer ring block 301 during operation.

[0033] Preferably, the protection sleeve 2 is further provided with a second positioning end 203 close to one end of the limiting plate block 1. As shown Figures 1-2 As shown, when the shaft protection kit is installed on the main device A02, the second positioning end 203 is placed in the protection cavity and is in close contact with the inner ring block 302 through the second through hole 101. Under this structure, the first positioning end 201 of the protection sleeve 2 is in close contact with the to-be-driven component A03, and the second positioning end 203 is in close contact with the inner ring block 302, which limits the movement range of the protection sleeve 2 in the left-right direction by the inner ring block 302 and the to-be-driven component A03, so that the protection end 202 does not need to be in close contact with the limiting plate block 1, greatly reducing the friction between the protection sleeve 2 and the limiting plate block 1. At the same time, under this structure, the rotation of the shaft body A01 will synchronously drive the rotation of the to-be-driven component A03 and the inner ring block 302, and the protection sleeve 2 clamped by the two will also rotate synchronously, so that the protection sleeve 2 will not rotate relative to the to-be-driven component A03 or the inner ring block 302 to cause abrasion, and overall, the abrasion of the shaft protection kit during long-term use is reduced.

[0034] Preferably, as shown Figure 2 and Figure 5 As shown, the supporting element 3 adopts a bearing component, which can provide support for the shaft body A01 while reducing the friction between the inner ring block 302 and the outer ring block 301, and reducing the resistance of the shaft body A01 during rotation.

[0035] Preferably, as shown Figure 2 As shown, when the shaft protection kit is installed on the main device A02, a first spacing L1 is formed between the limiting side wall of the limiting groove 102 and the protection end 202, and the first spacing L1 is smaller than the depth of the limiting groove 102. Under this structure, the protection end 202 of the protection sleeve 2 can still cooperate with the limiting groove 102 to protect the gap between the shaft body A01 and the second through hole 101, avoiding the entry of waste materials; at the same time, the contact area between the protection sleeve 2 and the limiting plate block 1 is reduced, further avoiding the friction between the two components caused by contact between the two components.

[0036] Preferably, as shown Figure 2As shown, the outer side wall of the main device A02 is provided with a receiving groove A02-2, and when the limiting plate 1 is installed on the outer side wall, a receiving cavity 4 is formed together with the receiving groove A02-2 to accommodate the supporting element 3. In this structure, when the supporting element 3 is damaged, the limiting plate 1 can be removed and taken out for replacement, improving the convenience of maintenance of the shaft protection kit in the later stage.

[0037] Embodiment 2:

[0038] In this embodiment, a bamboo strip drawing equipment is provided, which comprises a conveying roller set comprising a plurality of sets of feeding roller devices arranged on a box. As shown, Figure 1 The upper and lower sets of feeding roller devices form a clamping effect to output the bamboo strips. Each set of feeding roller device comprises a transmission shaft, a feeding roller, and a shaft protection kit of embodiment 1. As shown, Figures 1-2 The feeding roller is installed on the transmission shaft away from the box, the limiting plate 1 is installed on the box, and the protective sleeve 2 is sleeved on the exposed part of the transmission shaft. In this embodiment, the box is the main device A02 described in embodiment 1, the transmission shaft is the shaft A01 described in embodiment 1, and the feeding roller is the driven component A03 described in embodiment 1.

[0039] Preferably, as shown, Figure 1 One side of the feeding roller is in contact with the first positioning end 201, and the other side is in contact with the limiting sleeve installed on the transmission shaft. In this structure, the feeding roller can be easily disassembled, and the shaft protection kit can also be easily disassembled, maintained, etc. The limiting sleeve can be any component or sleeve that is easy to install and disassemble, such as a latch.

[0040] Preferably, as shown, Figures 1-2 The limiting sleeve comprises a thread B01 arranged on the transmission shaft and a threaded fastener B02 installed on the transmission shaft through the thread B01. In this structure, not only can the feeding roller be quickly assembled and disassembled, but also the tightness between the feeding roller and the protective sleeve 2 can be adjusted by adjusting the position of the threaded fastener B02, etc., to ensure that the protection end 202 can be embedded in the limiting groove 102, and then to ensure that the gap between the transmission shaft and the second through hole 101 is always in the protection cavity, and the waste such as bamboo powder cannot enter or block the gap.

[0041] Embodiment 3:

[0042] In this embodiment, a bamboo strip processing production line is provided, in which the bamboo strip drawing equipment of embodiment 2 is used in the bamboo strip processing step. The operation of the bamboo strip drawing equipment is relatively stable, and the interruption of bamboo strip transportation caused by the stopping of the feeding roller is less likely to occur, making the overall process of bamboo strip production more smooth and the qualified rate of processed bamboo strips higher.

[0043] Finally, it should be noted that: the above implementation cases are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing implementation cases, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing implementation cases, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the implementation cases of the present application.
