[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-5 In this embodiment of the present invention, a carding roller for a carding machine that is easy to replace and disassemble includes a roller assembly 1 consisting of a roller body 101 and a roller shaft 102. The roller shaft 102 is symmetrically fixed at both ends of the roller body 101. A plurality of convex strip grooves 108 are circumferentially opened on the outer side of the roller body 101. The convex strip grooves 108 penetrate through both ends of the roller body 101. The roller body 101 is connected to a needle assembly 2 through the convex strip grooves 108.

[0032] The needle assembly 2 includes an arc-shaped plate 201, a convex butt strip 202, and a needle 203;

[0033] The convex butt bar 202 is fixed to the lower surface of the arc plate 201, and the needle 203 is embedded and fixed inside the arc plate 201 and protrudes to the upper surface of the arc plate 201. The convex butt bar 202 is horizontally inserted into the inner side of the convex strip groove 108 to realize the assembly connection between the arc plate 201 and the roller body 101.

[0034] Quick-lock components 3 are provided on both sides of the roller body 101. The quick-lock components 3 are used to block and unlock the port of the convex strip groove 108, and to facilitate the easy assembly and disassembly of the needle assembly 2.

[0035] The quick-lock assembly 3 includes a sector-shaped baffle 301, a convex locking block 302, a W-shaped spring 303, an annular pressure seat 304, and a clamping bolt 307;

[0036] The roller body 101 has annular grooves 106 at both ends, and a convex groove 107 is provided on the outer ring side of the annular groove 106.

[0037] The convex block 302 is fixed to one end of the fan-shaped baffle 301. The fan-shaped baffle 301 is attached to the end face of the roller body 101 and is limited and slidably connected to the convex slot 107 through the convex block 302. The fan-shaped baffle 301 extends to the port of the convex strip groove 108 to block the port of the convex strip groove 108.

[0038] W-shaped spring 303 is distributed between the convex locking block 302 and the inner ring side of the annular groove 106. One end of the W-shaped spring 303 is welded and fixed to the convex locking block 302, and the other end is tightly fitted to the inner ring side of the annular groove 106. The W-shaped spring 303 is used to provide the fan-shaped baffle 301 and the convex locking block 302 as a whole with a thrust toward the outside of the roller body 101.

[0039] A first circular seat 103 and a second circular seat 104 are fixed sequentially on the outer side of the roller 102. The first circular seat 103 is close to the annular groove 106, and the second circular seat 104 is distributed at the end of the first circular seat 103 away from the annular groove 106.

[0040] The annular pressure seat 304 is slidably connected to the outside of the first round seat 103, and the clamping bolt 307 is threadedly connected to the second round seat 104 and passes through the second round seat 104 and is tightly fitted to the end face of the annular pressure seat 304.

[0041] The annular pressure seat 304 is pressed by the clamping bolt 307, which causes the annular pressure seat 304 to simultaneously press multiple sector baffles 301 to achieve position locking of multiple sector baffles 301.

[0042] An annular baffle 105 is fixed on the outer side of the first round seat 103 near the annular groove 106;

[0043] The annular pressure seat 304 has a storage groove 305 at one end near the annular groove 106. A spring 306 is provided inside the storage groove 305. The spring 306 is sleeved on the outside of the annular baffle 105 and is in close contact with the inner wall end face of the storage groove 305 and the end face of the annular baffle 105.

[0044] In this embodiment: when the carding needles 203 need to be replaced, only the multiple carding needle assemblies 2 need to be replaced sequentially. The operation steps are as follows:

[0045] First, loosen the clamping bolt 307 with a tool to release the clamping bolt 307 from the clamping operation of the annular pressure seat 304. At this time, the annular pressure seat 304 moves away from the sector baffle 301 under the elastic force of the spring 306, thereby releasing the clamping operation of the sector baffle 301.

[0046] Next, manually press the fan-shaped baffle 301 downwards. The fan-shaped baffle 301 moves down along the trajectory of the convex groove 107 through the convex block 302 and squeezes the W-shaped spring 303 to further deform and shrink. Finally, the fan-shaped baffle 301 releases the blockage of the opening of the convex strip groove 108. At this time, the entire needle assembly 2 can be pulled out along the opening of the convex strip groove 108, thus completing the removal of a single needle assembly 2.

[0047] Next, rotate the roller 101 so that the needle assembly 2 to be removed is rotated to the top and disassembled according to the above operation. Then, install the new needle assembly 2 in sequence. Finally, tighten the clamping bolt 307. The overall operation is simple and convenient, which effectively improves the replacement efficiency of the needle 203.

[0048] Please refer to this carefully. Figures 1-4 The bottom of a single arc plate 201 is provided with two convex connecting strips 202. The two convex connecting strips 202 are used to be inserted synchronously with two convex strip grooves 108. The number of convex strip grooves 108 is twice the number of convex slots 107. The number of fan-shaped baffles 301 matches the number of convex slots 107, and a single fan-shaped baffle 301 simultaneously blocks the ports of the two convex strip grooves 108.

[0049] There is a gap between two adjacent sector baffles 301.

[0050] In this embodiment: by providing two convex connecting strips 202 at the bottom of a single arc plate 201, the connection force between the arc plate 201 and the roller body 101 can be further improved, ensuring the stability of the needle 203;

[0051] The structure with a gap between two adjacent sector baffles 301 provides space for the downward movement of the sector baffles 301, so that the two adjacent sector baffles 301 do not interfere with each other.

[0052] Please refer to this carefully. Figures 1-4 The contact surfaces of the fan-shaped baffle 301 and the annular pressure seat 304 are both arc-shaped.

[0053] In this embodiment, the contact arc surfaces of the fan-shaped baffle 301 and the annular pressure seat 304 are used to reduce the squeezing friction when they come into contact with each other. It should also be noted that multiple clamping bolts 307 are arranged around the circumference to ensure the pressure balance of the annular pressure seat 304. In addition, block locking assemblies 3 are provided at both ends of the roller body 101, so that the needle assembly 2 can be disassembled and assembled at both ends of the roller body 101. In actual operation, the more convenient end can be selected for disassembly and assembly according to the site layout.

[0054] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
