Description

Technical Field

[0001] This utility model belongs to the field of combing machine equipment, specifically relating to a cover plate type cotton passage plate for a combing machine. Background Technology

[0002] The cotton pass plate of the combing machine is located at the input end of the nipper plate. It is used to send the cotton web after the cotton lap is disassembled to the feeding roller holding jaws inside the nipper plate. During the conveying process, the cotton web is initially straightened by the swing of the cotton pass plate body and the clamping action of the jaws on the cotton web.

[0003] As the operating speed of existing combing machines has increased from 350 nips to 450-500 nips, the oscillation frequency of the guide plate and the clamping speed of the jaws also need to be increased accordingly to adapt to this speed. In existing guide plates, slit structures for inserting cover plates are provided on both the left and right sides of the guide plate body. These slit structures consist of side plates located on the left and right sides of the guide plate body. When the cotton web passes through the cotton passage composed of the guide plate body, side plates, and cover plates, the oscillation of the guide plate and the clamping action of the jaws cause the cover plates and the guide plate body to squeeze and stretch the cotton web, initially straightening it. However, since the cover plates are set in the guide plate through the slit structure, they will move slightly within the slit structure when the guide plate oscillates. This causes the cross-sectional area of ​​the cotton passage to change with the oscillation of the guide plate, i.e., fluctuating in size. This situation will cause the straightness and uniformity of the cotton web output by the guide plate to deteriorate, ultimately resulting in the quality of the cotton sliver output by the combing machine failing to meet requirements. Utility Model Content

[0004] In view of this, the present invention proposes a cover plate type cotton passage plate for a combing machine, which connects the cover plate and the L-shaped fastening plate into one piece. Based on the matching of the mounting hole and the mounting protrusion, the vertical part and the side plate being attached, and a set of first folding parts being embedded between a set of side plates, the cross-sectional area of ​​the cotton passage channel formed by the cover plate and the cotton passage plate body is kept in a fixed state, so as to avoid the cross-sectional area of ​​the cotton passage channel changing when the cotton passage plate swings.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A cover-type cotton passer for a combing machine, comprising:

[0007] The cotton-passing board body has an overall isosceles trapezoidal flat plate structure. A set of parallel sides of the cotton-passing board body are respectively configured as long side and short side, and the long side and short side are connected to each other through a set of side sides. The long side, short side, and set of side sides enclose and form the cotton-passing board body.

[0008] A set of side plates are correspondingly provided on a set of the side portions, and the set of side plates and the cotton board body are combined to form a U-shaped structure. In addition, on the set of side plates, a set of mounting protrusions are provided on the two opposite sides.

[0009] The cover plate includes a main body, on both sides of which a set of first folding portions are symmetrically arranged, and the set of first folding portions and the main body are combined to form an n-shaped structure. In addition, the cover plate is embedded between a set of side plates through the set of first folding portions, and the main body and the cotton-passing plate body are far apart from each other, so that a cotton-passing channel is formed between the cover plate and the cotton-passing plate body. After the cotton web is disassembled from the cotton roll, it enters the cotton-passing channel from the long side of the cotton-passing plate body and exits from the short side.

[0010] A set of L-shaped fastening plates are symmetrically arranged on both sides of the cotton-filled board body. Each L-shaped fastening plate consists of an integrally formed horizontal part and a vertical part. The horizontal part is located above the main body part, and a pad is provided between the horizontal part and the main body part. The L-shaped fastening plate and the cover plate are connected as one unit through the pad. The vertical part is in contact with the side plate. In addition, the vertical part is provided with mounting holes, which cooperate with mounting protrusions.

[0011] Preferably, the cotton-passing plate body is provided with several reinforcing ribs on the side away from the cotton-passing channel, and the several reinforcing ribs interweave to form a mesh structure.

[0012] More preferably, on the cover plate, the main body is provided with a second folding portion on the side near the long side, and the second folding portion folds away from the cotton board body, and the included angle A between the second folding portion and the main body is in the range of 135° to 145°.

[0013] Furthermore, the width of the cotton passage near the long side is 10mm to 12mm, and the width of the cotton passage near the short side is 7mm to 9mm, wherein the width of the cotton passage is the distance between the cotton passage plate body and the cover plate.

[0014] Furthermore, the material of the cotton-filled board body is nylon 66 + glass fiber, and the material of the cover plate and a set of L-shaped fastening plates is 1Cr18Ni9Ti steel plate.

[0015] The beneficial effects of this utility model are as follows:

[0016] In general, this utility model connects and combines the original slit structure in the cotton-passing board with the cover plate. Side plates and L-shaped fastening plates are respectively set on both sides of the cotton-passing board body. The vertical part of the L-shaped fastening plate is attached to the side plate, the mounting holes on the vertical part cooperate with the mounting protrusions on the side plate, and a set of first folding parts on the cover plate are embedded between a set of side plates. Furthermore, with the horizontal part of the L-shaped fastening plate connected to the main body of the cover plate by a pad, the cover plate is fixedly fastened to one side of the cotton-passing board body, forming a structurally stable cotton-passing channel. This solves the problem that the cross-sectional area of ​​the cotton-passing channel changes with the swing of the cotton-passing board during the operation of the combing machine due to the original insert-type connection method of the cover plate and slit structure. This ensures that the straightness of the cotton web output by the cotton-passing board is always uniform during the operation of the combing machine, which is beneficial to improving the overall quality of the cotton sliver output by the combing machine.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0024] The solution provided by this utility model will now be described in detail with reference to the accompanying drawings.

[0025] In this technical solution, such as Figure 1 As shown, a cover-type cotton guide plate for a combing machine includes: a cotton guide plate body 1, a side plate 2, a cover plate 3, and an L-shaped fastening plate 4.

[0026] like Figure 1-2 As shown, the cotton-passing board body 1 is an isosceles trapezoidal flat plate structure. A set of parallel sides of the cotton-passing board body 1 are respectively configured as a long side 101 and a short side 102, and the long side 101 and the short side 102 are connected to each other through a set of side parts. The long side 101, the short side 102, and the set of side parts enclose and form the cotton-passing board body 1.

[0027] Based on the above embodiments, the cotton passer plate body 1 is the main load-bearing body of the entire cotton passer plate structure, mainly bearing the main load-bearing function of the cotton web. In addition, the cotton passer plate body 1 also serves as the structural connection with the upstream and downstream equipment in the combing machine. Furthermore, the material of the cotton passer plate body 1 is nylon 66 + glass fiber, and the surface roughness is 1.6. Utilizing the antistatic properties of this material, the cotton web will not get caught on fibers or generate cotton knots when passing through the cotton passer plate body 1, which is beneficial to the straightening of the cotton web.

[0028] Based on this, such as Figure 1 As shown, the combing machine cover plate type cotton passage plate also includes a set of side plates 2 correspondingly provided on a set of side parts, and the set of side plates 2 and the cotton passage plate body 1 are combined to form a U-shaped structure. In addition, on the set of side plates 2, a set of mounting protrusions 201 are provided on the two opposite sides.

[0029] like Figure 1-2 As shown, the cover plate 3 includes a main body 301, and a set of first folding parts 302 are symmetrically arranged on both sides of the main body 301. The set of first folding parts 302 and the main body 301 are combined to form an n-shaped structure.

[0030] Based on the above structure, the cover plate 3 is embedded between a set of side plates 2 through a set of first folding parts 302, and the main body 301 is far away from the cotton board body 1, so that a cotton passage channel 5 is formed between the cover plate 3 and the cotton board body 1. After the cotton web is disassembled from the cotton roll, it enters the cotton passage channel 5 from the long side 101 of the cotton board body 1 and is output from the short side 102. Due to the difference in length between the long side 101 and the short side 102, the cotton web is initially tightened in width when it is output, and in conjunction with the width of the subsequent clamping device, the cotton web is more easily put into the clamp.

[0031] Based on this, such as Figure 1-2 As shown, the combing machine cover plate also includes a set of L-shaped fastening plates 4 symmetrically arranged on both sides of the cover plate body 1. Each L-shaped fastening plate 4 is composed of an integrally formed horizontal part 401 and a vertical part 402. The horizontal part 401 is located above the main body part 301, and a pad 403 is provided between the horizontal part 401 and the main body part 301. The L-shaped fastening plate 4 and the cover plate 3 are connected as a whole by the pad 403. The vertical part 402 is in contact with the side plate 2. On this basis, the vertical part 402 is also provided with a mounting hole 404, which cooperates with the mounting protrusion 201.

[0032] Based on the above embodiments, with the vertical part 402 of the L-shaped fastening plate 4 fitting against the side plate 2, the mounting hole 404 on the vertical part 402 cooperating with the mounting protrusion 201 on the side plate 2, and a set of first folding parts 302 on the cover plate 3 embedded between a set of side plates 2, and with the horizontal part 401 of the L-shaped fastening plate 4 and the main body part 301 of the cover plate 3 connected as one unit by a pad 403, the cover plate 3 is fixedly fastened to one side of the cotton passage plate body 1, forming a structurally stable cotton passage channel 5. This ensures that when the cover plate type cotton passage plate of the combing machine works and swings inside the combing machine, the cross-sectional area of ​​the cotton passage channel 5 will not change due to the swinging of the cover plate 3. In addition, the materials of the cover plate 3 and the set of L-shaped fastening plates 4 are all 1Cr18Ni9Ti steel plates.

[0033] In addition, such as Figure 3 As shown, the cotton-passing board body 1 is provided with several reinforcing ribs 103 on the side away from the cotton-passing channel 5, and the several reinforcing ribs 103 interweave to form a mesh structure, which is beneficial to enhance the structural strength of the cotton-passing board body 1 and increase its service life.

[0034] In this technical solution, such as Figure 1-2 , Figure 4 As shown, on the cover plate 3, the main body 301 is provided with a second folding part 303 on the side near the long side 101, and the second folding part 303 is folded away from the cotton board body 1. It is used to provide guidance and limit when the cotton web enters the cotton passage 5 from the port near the long side 101, and to prevent the cotton web from moving from the outside of the cotton passage 5. Based on this, the included angle α between the second folding part 303 and the main body 301 is in the range of 135° to 145°.

[0035] In the cotton passage 5 proposed in this application, such as Figure 1 , Figure 4 As shown, the width B of the cotton passage 5 near the long side 101 is 10mm to 12mm, and the width C of the cotton passage 5 near the short side 102 is 7mm to 9mm. The width of the cotton passage 5 is the distance between the cotton passage plate body 1 and the cover plate 3.

[0036] Based on the above embodiments, the cotton passage 5 is configured with the above structure so that the cotton web is compressed in thickness when it passes through the cotton passage 5 of the cover-type cotton passage plate of the combing machine. In addition, the straightening effect of the cover-type cotton passage plate of the combing machine on the cotton web is more obvious due to the swing of the cotton passage plate and the clamping action of the jaws.

[0037] Specifically, this utility model connects and combines the original gap structure in the cotton-passing plate with the cover plate. Side plates 2 and L-shaped fastening plates 4 are respectively provided on both sides of the cotton-passing plate body 1. Based on the vertical part 402 of the L-shaped fastening plate 4 being attached to the side plate 2, the mounting hole 404 on the vertical part 402 cooperating with the mounting protrusion 201 on the side plate 2, and a set of first folding parts 302 on the cover plate 3 being embedded between a set of side plates 2, and with the horizontal part 401 of the L-shaped fastening plate 4 and the main body part 301 of the cover plate 3 being connected as a whole by a pad 403, the cover plate 3 is fixedly fastened to one side of the cotton-passing plate body 1, forming a structurally stable cotton-passing channel 5. This solves the problem that the cross-sectional area of ​​the cotton-passing channel changes with the swing of the cotton-passing plate when the comber is working, due to the original insert connection method of the cover plate and the gap structure. This ensures that the straightness of the cotton web output by the cotton-passing plate is always uniform during the operation of the comber, which is beneficial to improving the overall quality of the cotton sliver output by the comber.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
