Description

Technical Field

[0001] This invention relates to the field of textile equipment technology, and more specifically, to a cotton feeding structure. Furthermore, this invention also relates to a carding machine including the aforementioned cotton feeding structure. Background Technology

[0002] The cotton feeding structure 10 is an important component of the carding machine. It is used to hold and pressurize the cotton layer 01 and input it into the licker-in structure 20, and cooperate with the licker-in structure 20 to open the cotton layer 01.

[0003] Because the fiber properties, body length and impurity content of different suitable fibers vary greatly, the yarn indicators of different yarn varieties are significantly different. Therefore, the feeding and combing length L1 (the distance from the lower end of the feeding plate 5 to the axis of the feeding roller 1), the feeding gap L2 (the minimum distance from the lower end of the feeding plate 5 to the circumferential surface of the feeding roller 1) and the feeding pressure of the feeding structure 10 can all be adjusted.

[0004] The existing carding machine's feeding structure 10, such as Figure 3 As shown, the cotton feeding roller 1 is installed between two fixed seats 2 via a horizontal shaft, and the cotton feeding plate 5 is located above the cotton feeding roller 1; a rotating seat 3 is sleeved on both sides of the horizontal shaft of the cotton feeding roller 1, and a pressure adjusting seat 4 is located above the rotating seat 3, with the pressure-applying shaft of the cotton feeding plate 5 sleeved in the pressure adjusting hole of the pressure adjusting seat 4.

[0005] Under the pressure of the adjusting nut 41 on the adjusting seat 4, the distance between the feed plate 5 and the feed roller 1 is extremely close. A spacing bolt 6 for adjusting the feed interval L2 is provided between the rotating seat 3 and the feed plate 5. One end of the spacing bolt 6 is located on the rotating seat 3, and the other end abuts against the feed plate 5. Tightening the spacing bolt 6 upwards causes the feed plate 5 to undergo elastic deformation and move upwards, increasing the feed interval L2; conversely, tightening the spacing bolt 6 downwards resets the feed plate 5, decreasing the feed interval L2.

[0006] The aforementioned cotton feeding structure 10 adjusts the cotton feeding distance L2 through extrusion deformation. The cumulative processing and assembly errors of the cotton feeding plate 5, pressure regulating seat 4, and rotating seat 3 result in a large adjustment error for the cotton feeding distance L2. Furthermore, the distance bolt 6 is located inside the equipment, resulting in a small operating space and relatively difficult adjustment. The pressure axis of the pressure regulating seat 4 is not in the same vertical plane as the horizontal axis of the cotton feeding roller 1, which leads to a large difference in the cotton feeding pressure between sessions.

[0007] In conclusion, how to accurately and conveniently adjust the cotton feeding structure is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0008] In view of this, the purpose of the present invention is to provide a cotton feeding structure in which the spacing bolt can drive the cotton feeding plate to move relative to the rotating seat, making operation convenient and allowing for more precise adjustment of the cotton feeding spacing.

[0009] In addition, the present invention also provides a carding machine including the above-described cotton feeding structure.

[0010] To achieve the above objectives, the present invention provides the following technical solution:

[0011] A cotton feeding structure includes a cotton feeding roller, a fixed seat, a rotating seat, a pressure adjusting seat, and a cotton feeding plate. The cotton feeding plate is disposed between the pressure adjusting seat and the cotton feeding roller. The upper end face of the cotton feeding plate is connected to the pressure adjusting surface of the pressure adjusting seat, and the pressure axis of the pressure adjusting seat is perpendicular to the upper end face of the cotton feeding plate.

[0012] A horizontally arranged spacing bolt is provided between the rotating seat and the cotton feeding plate. One end of the spacing bolt is connected to the side of the cotton feeding plate, and the other end of the spacing bolt is connected to the vertical adjustment plate on the outside of the rotating seat, so as to drive the cotton feeding plate to translate relative to the rotating seat and thereby adjust the cotton feeding spacing L2.

[0013] Preferably, the side of the cotton feeding plate is provided with a threaded mounting hole, and one end of the spacing bolt is located in the bolt mounting hole and locked by a lock nut.

[0014] Preferably, the vertical adjustment plate has a through hole for the spacing bolt to pass through, and the spacing bolt is fitted with an adjusting nut on at least one side of the vertical adjustment plate.

[0015] Preferably, a combing length bolt is provided between the rotating seat and the fixed seat. One end of the combing length bolt is hinged to the rotating seat, and the other end of the combing length bolt is sleeved in the mounting base of the fixed seat and connected to the adjusting nut.

[0016] Preferably, the comb length bolt includes a hinge bolt, which is hinged to the rotating seat via a pin.

[0017] Preferably, the comb length bolts are fitted with adjusting nuts at both ends of the mounting base.

[0018] A carding machine includes a licker-in roller structure and a feeding structure as described in any of the preceding claims.

[0019] In the initial state, the pressure axis of the pressure regulating seat of the cotton feeding structure provided by the present invention is set vertically, and the upper end face of the cotton feeding plate is perpendicular to the pressure axis, that is, the upper end face of the cotton feeding plate is set horizontally. Therefore, turning the horizontally set spacing bolt can drive the cotton feeding plate to translate relative to the rotating seat, thereby adjusting the distance between the cotton feeding plate and the cotton feeding roller (cotton feeding distance L2). Compared with the prior art, which uses the elastic deformation of the cotton feeding plate to adjust the cotton feeding distance L2, the cotton feeding distance L2 adjustment of the above-mentioned cotton feeding structure is more accurate and less susceptible to the influence of processing and assembly errors.

[0020] The pressure regulating seat and the spacing bolt are relatively independent, with a suitable operating space and less interference. The spacing bolt is connected to the vertical adjustment plate on the outside of the rotating seat. Sufficient operating space is reserved through the external spacing bolt, making adjustment convenient.

[0021] The pressure regulating seat's pressure axis is perpendicular to the upper end face of the cotton feeding plate, so the cotton feeding pressure acts directly on the cotton feeding plate, resulting in uniform and stable pressure and low pressure per cycle.

[0022] In addition, the present invention also provides a carding machine including the above-described cotton feeding structure. Attached Figure Description

Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] The core of this invention is to provide a cotton feeding structure in which the spacing bolts can drive the cotton feeding plate to move relative to the rotating seat, making operation convenient and allowing for more precise adjustment of the cotton feeding spacing.

[0037] In addition, the present invention also provides a carding machine including the above-described cotton feeding structure.

[0038] Please refer to Figures 5-9 .

[0039] The cotton feeding structure provided by the present invention includes a cotton feeding roller 1, a fixed seat 2, a rotating seat 3, a pressure regulating seat 4, and a cotton feeding plate 5. The cotton feeding plate 5 is disposed between the pressure regulating seat 4 and the cotton feeding roller 1. The upper end face of the cotton feeding plate 5 is connected to the pressure regulating surface of the pressure regulating seat 4. The pressure axis of the pressure regulating seat 4 is arranged in the vertical direction and is perpendicular to the upper end face of the cotton feeding plate 5.

[0040] A horizontally arranged spacing bolt 6 is provided between the rotating seat 3 and the cotton feeding plate 5. One end of the spacing bolt 6 is connected to the side of the cotton feeding plate 5, and the other end of the spacing bolt 6 is connected to the vertical adjustment plate 34 on the outside of the rotating seat 3, so as to drive the cotton feeding plate 5 to move relative to the rotating seat 3 and thereby adjust the cotton feeding spacing L2.

[0041] Please refer to Figure 5 The cotton feeding roller 1 is mounted between two fixed seats 2 on both sides via a horizontal shaft, and a rotating seat 3 is fitted on both sides of the horizontal shaft. The cotton feeding plate mounting seat 32 of the rotating seat 3 is connected to the cotton feeding plate side plate 51 of the cotton feeding plate 5 via a rotating shaft 31. The cotton feeding plate side plate 51 can rotate around the rotating shaft 31 under the action of gravity. The upper part of the rotating seat 3 is connected to the pressure regulating seat 4. The adjusting nut mounting plate of the pressure regulating seat 4 is connected to the rotating seat 3 via common connecting parts such as fastening bolts and fixing pins.

[0042] Please refer to Figure 7The cotton feeding plate mounting base 32 of the rotating seat 3 is provided with a connecting pin 33. The cotton feeding plate side plate 51 is provided with a rectangular connecting groove arranged along the movement direction of the spacer bolt 6. The connecting pin 33 is located in the rectangular connecting groove. The upper end face of the rectangular connecting groove abuts against the upper end face of the connecting pin 33. A gap is provided between the lower end face of the rectangular connecting groove and the lower end face of the connecting pin 33.

[0043] It should be noted that the length of the waist-shaped hole should be greater than or equal to the sum of the diameter of the fastener and the maximum difference between the feed spacing L2, so as not to hinder the normal adjustment process of the feed spacing L2.

[0044] The upper end face of the cotton feeding plate 5 is connected to the pressure regulating surface of the pressure regulating seat 4, and the pressure regulating axis of the pressure regulating seat 4 is perpendicular to the upper end face of the cotton feeding plate 5. Therefore, the cotton feeding pressure can be directly applied to the cotton feeding plate 5. Compared with the prior art, the pressure is uniform and stable, and the pressure per cycle is small.

[0045] The spacing bolt 6 is set horizontally, with one end vertically connected to the side of the cotton feeding plate 5 and the other end vertically connected to the vertical adjustment plate 34 of the rotating seat 3; the relative position of at least one of the cotton feeding plate 5 and the rotating seat 3 with respect to the spacing bolt 6 is adjustable so that the distance between the cotton feeding plate 5 and the vertical adjustment plate 34 can be adjusted by turning the spacing bolt 6.

[0046] Before use, the feeding combing length L1 (the distance from the lower end of the feeding plate 5 to the axis of the feeding roller 1), the feeding gap L2 (the minimum distance from the lower end of the feeding plate 5 to the circumferential surface of the feeding roller 1), and the feeding pressure of the feeding structure 10 need to be adjusted according to the type of suitable fiber and yarn.

[0047] In the initial state, such as Figure 5 and Figure 6 As shown, the pressure axis of the adjusting seat 4 is set in the vertical direction, while the upper end face of the cotton feeding plate 5 is perpendicular to the pressure axis, that is, the upper end face of the cotton feeding plate 5 is set horizontally. Therefore, turning the horizontally set spacing bolt 6 can drive the cotton feeding plate 5 to move relative to the rotating seat 3, thereby adjusting the distance (cotton feeding spacing L2) between the cotton feeding plate 5 and the cotton feeding roller 1.

[0048] It should be noted that, if the installation error between the cotton feeding plate 5 and the cotton feeding roller 1 is not considered, the distance by which the rotating gap bolt 6 drives the cotton feeding plate 5 to move is equal to the adjustment distance of the cotton feeding gap L2.

[0049] Compared to the existing technology that uses the elastic deformation of the cotton feeding plate 5 to adjust the cotton feeding distance L2, the adjustment of the cotton feeding distance L2 in this embodiment is more precise and less susceptible to the influence of processing and assembly errors.

[0050] The pressure regulating seat 4 and the spacing bolt 6 are relatively independent, with a suitable operating space and less interference, making it easy to adjust the various parameters of the cotton feeding structure 10;

[0051] The spacing bolt 6 is connected to the vertical adjustment plate 34 on the outside of the rotating seat 3. The spacing bolt 6 provides sufficient operating space for easy adjustment.

[0052] The pressure regulating seat 4 has its pressure axis perpendicular to the upper end face of the cotton feeding plate 5. The cotton feeding pressure is directly applied to the cotton feeding plate 5, resulting in uniform and stable pressure and low pressure per cycle.

[0053] Preferably, the cotton feeding plate 5 can be provided with threaded mounting holes on its side, and one end of the spacer bolt 6 can be placed in the bolt mounting hole and locked by a lock nut, thereby fixing the spacer bolt 6 and the cotton feeding plate 5.

[0054] The cotton feeding plate 5 is fixedly connected to the spacing bolt 6. Therefore, when the spacing bolt 6 moves relative to the vertical adjusting plate 34, it will cause the cotton feeding plate 5 to move relative to the vertical adjusting plate 34, thereby adjusting the cotton feeding spacing L2. Compared with the spacer bolt 6 being movably connected to the cotton feeding plate 5, the operating space is more sufficient, making adjustment easier.

[0055] Preferably, the vertical adjustment plate 34 is provided with a through hole for the spacer bolt 6 to pass through, and the spacer bolt 6 is provided with an adjustment nut on at least one side of the vertical adjustment plate 34.

[0056] Tightening the adjusting nut can cause the spacing bolt 6 to move relative to the vertical adjusting plate 34, which in turn causes the cotton feeding plate 5 to move relative to the vertical adjusting plate 34, thus adjusting the cotton feeding spacing L2. Compared with the threaded connection between the vertical adjusting plate 34 and the spacing bolt 6, the adjustment process is simpler.

[0057] Please refer to Figure 8 The spacer bolts 6 are provided with adjusting nuts on both sides of the vertical adjusting plate 34 to adjust the spacer bolts 6 to be relatively closer to or farther away from the vertical adjusting plate 34.

[0058] Based on the above embodiment, a combing length bolt 7 is provided between the rotating seat 3 and the fixed seat 2. One end of the combing length bolt 7 is hinged to the rotating seat 3, and the other end of the combing length bolt 7 is sleeved in the mounting seat of the fixed seat 2 and connected to the adjusting nut.

[0059] It should be noted that the mounting base here can be a mounting boss that protrudes from the surface of the fixing base 2, or it can be like... Figure 9 The image shows the fastening bolt 21 that is threadedly connected to the fixed base 2.

[0060] When the adjusting nut is turned, the combing length bolt 7 moves along its axial direction. The combing length bolt 7 drives the rotating seat 3 to rotate around the feed roller 1, so that the feed plate 5 of the rotating seat 3 rotates around the feed roller 1, thereby changing the minimum distance from the lower end face of the feed plate 5 to the circumferential surface of the feed roller 1, thus completing the adjustment of the feed combing length L1.

[0061] To facilitate the movement of the combing length bolt 7 along the axial direction to both sides, preferably, adjusting nuts can be fitted on both ends of the mounting base for the combing length bolt 7.

[0062] In this embodiment, the combing length bolt 7 is externally mounted, which is convenient for adjustment and allows for adjustment of the cotton feeding combing length L1 when the equipment is running, facilitating process adjustment.

[0063] To facilitate the connection between the combing length bolt 7 and the rotating seat 3, preferably, the combing length bolt 7 includes a hinge bolt, which is hinged to the rotating seat 3 via a pin 35.

[0064] In addition to the cotton feeding structure 10 described above, the present invention also provides a carding machine including the cotton feeding structure 10 disclosed in the above embodiments. The carding machine includes a licker-in roller structure 20 and the cotton feeding structure 10 disclosed in the above embodiments. For the structure of other parts of the carding machine, please refer to the prior art, which will not be described in detail here.

[0065] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0066] The carding machine and its cotton feeding structure provided by this invention have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this invention.
