Description

Technical Field

[0001] The present invention relates to the field of cotton primary processing machinery, and particularly to a waste removal knife mounting structure and a lint cleaner. Background Art

[0002] The waste removal knife is the core working component of the lint cleaner; in the prior art, in order to improve the waste removal efficiency of the lint cleaner, the carding device used in the carding machine is applied to the lint cleaner. The lint cleaner is a front-end device for cotton processing, and the carding machine is a back-end device for cotton processing.

[0003] First, in terms of structural stability, since the length of the cutter of the carding machine generally reaches about 1 meter, while the working length of the waste removal knife of the lint cleaner generally reaches the 2-3 meter level; the existing manufacturing process is difficult to ensure a uniform and stable working gap is formed between the cutting edge of the waste removal knife, the cotton fiber carding device and the barbed roller, especially when operating at high speed, millimeter-level deformation is likely to occur, resulting in a sharp decline in the carding efficiency.

[0004] Secondly, in terms of dynamic load-bearing capacity, the impact load generated by the linear velocity of 20-30 m / s of the barbed roller of the lint cleaner is 3-5 times higher than that of the carding machine; during operation, the cotton fibers directly impact the carding device. If the fixing method of the cutter of the carding machine is adopted: welding angle steel on the back of the cutter, and indirectly fixing the carding device on the machine wall panel through the angle steel; then it cannot meet the impact requirements of the carding device on the lint cleaner.

[0005] Finally, in terms of process adaptability, for the lint cleaner using the carding device, during operation, some cotton fibers are likely to break away from the barbed roller, and it is required to set a smaller waste removal section than the traditional lint cleaner to prevent cotton fiber loss.

[0006] Therefore, the prior art has not been able to break through the problem of the collaborative optimization of the structural stability, dynamic reliability, process adaptability and manufacturing economy of the comb-type waste removal knife body, which severely restricts the application of this carding device on the lint cleaner. Summary of the Invention

[0013] According to the above technical solution, a set screw hole is provided on the fixing sleeve or at the corresponding installation position of the mechanical wallboard, and a set screw is provided in the set screw hole; The carding component, the additional waste removing knife, and the cotton pressing plate are arranged along the length direction of the comb-type waste removing knife body, and the lengths of all three do not exceed the distance between the fixing sleeves at both ends of the comb-type waste removing knife body.

[0014] According to the above technical solution, the comb-type waste removing knife body is hollowly provided, and an inner cavity penetrating through the end face of the comb-type waste removing knife body is provided inside; A fixing hole for connecting with an external mechanical wallboard is provided on the fixing sleeve; a limiting hole is provided in the middle of the fixing sleeve, and both ends of the comb-type waste removing knife body are placed in the limiting hole, and the two are connected with a clearance fit; a fixing block is further included and is placed in the inner cavity, and the fixing block, the comb-type waste removing knife body, and the fixing sleeve are on the same vertical plane, and the three are fixedly connected by a first fastening member.

[0015] According to the above technical solution, the cross-section of the comb-type waste removing knife body is in a quadrilateral structure, and further includes a second side, a third side, and a fourth side; the first gap adjusting member is fixedly installed on the second side through a second fastener, and the second adjusting member is fixedly installed on the fourth side through a third fastener, and the third side and the first side are on opposite sides of the comb-type waste removing knife body; The fixing sleeves are sleeved at both ends of the comb-type waste removing knife body and are attached to the first side, the second side, the third side, and the fourth side surfaces.

[0016] In a second aspect, a lint cleaner includes a mechanical wallboard, a barbed roller, and a plurality of waste removing knife mounting structures as described in any one of the above. The barbed roller is rotatably connected between the mechanical wallboards; a plurality of waste removing knife mounting structures are arranged at intervals on the arc surface outside the barbed roller, and a working gap is left between the first side and the outer wall surface of the barbed roller; the gap between two adjacent waste removing knife mounting structures is within a set gap range.

[0017] According to the above technical solution, the fixing sleeves on the same side of all waste removing knife mounting structures are mutually attached to each other.

[0018] The present invention has the following beneficial effects: 1. The method of using the fixing sleeve to fix the comb-type waste removing knife body not only ensures the stability of the fixing of the comb-type waste removing knife body on the mechanical wallboard, ensures the uniform stability of the gap between the comb-type waste removing knife body and the barbed roller; but also can improve the impact resistance of the comb-type waste removing knife body, and can be better applied to the lint cleaner.

[0019] 2. A first gap adjusting member is provided at the front end of the first side of the comb-type waste removing knife body, such as the accessory waste removing knife in the figure, which can not only protect the cutting edge of the aluminum alloy comb-type waste removing knife, but also adjust the distance between two adjacent comb-type waste removing knife bodies, so as to reduce the waste removing section and thus reduce the loss of cotton fibers. Or, a second gap adjusting member is provided at the rear side of the comb-type waste removing knife body, and the second gap adjusting member is used to separately adjust the distance between two adjacent comb-type waste removing knife bodies, so as to reduce the waste removing section and thus reduce the loss of cotton fibers.

[0020] 3. Due to the limitation of the preferred thickness range of the first gap adjusting member, if the first gap adjusting member provided at the front end of the first side of the comb-type waste removing knife body cannot meet the gap adjustment requirements between two adjacent comb-type waste removing knife bodies, a second gap adjusting member, such as a cotton pressing plate, is provided at the rear end of the first side of the comb-type waste removing knife body. On the contrary, if the second gap adjusting member cannot meet the gap adjustment requirements, a first gap adjusting component can be added. Therefore, the first gap adjusting member and the second gap adjusting member jointly adjust the gap between two adjacent comb-type waste removing knife bodies installed on the external lint cleaner to prevent the loss of cotton fibers.

[0021] 4. The fitting connection between adjacent fixed sleeves can, first, shorten the impurity removal section where the bodies of adjacent comb-type impurity removal knives are located at the fixed sleeves; second, the previously installed fixed sleeve serves as a positioning component for the subsequently installed fixed sleeve, reducing the installation difficulty of the bodies of the comb-type impurity removal knives; third, prevent free cotton fibers from hanging at the gaps between the fixed sleeves; and fourth, allow for the installation of more impurity removal knives, improving the impurity removal efficiency of the lint cleaner.

[0022] 5. There are set screw holes on the fixed sleeves or on the machine wall panels at the corresponding installation positions of the fixed sleeves, and set screw bolts are provided in the set screw holes; this meets the requirement for the body of the comb-type impurity removal knife to bend towards the licker-in roller or away from the licker-in roller.

[0023] 6. The tooth density of the carding component does not exceed 40 teeth per square centimeter; this can both meet the need for high output and avoid damaging cotton fibers. The working tooth height of the licker-in bars provided on the surface of the licker-in roller is not less than 0.5 mm; this can both increase the fiber capacity and output and ensure the impurity removal effect.

Detailed implementation manners

[0027] The following combines the attached Figures 1-11 The principles and features of the present invention are described below. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention. In the following paragraphs, the present invention is described more specifically by way of example with reference to the accompanying drawings. The advantages and features of the present invention will be clearer according to the following description and the claims. It should be noted that the drawings are all in a very simplified form and use non-precise scales, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0028] It should be noted that when a component is referred to as "fixed to" another component, it can be directly on the other component or there can also be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0030] Refer to Figures 1 to 11 As shown, the waste removing knife mounting structure provided by the present invention.

[0031] Example 1 Refer to Figures 1 to 4 As shown, it includes a carding component 1 and a comb-type waste removing knife body 2; the comb-type waste removing knife body includes a first side 2-1 disposed opposite to an external barbed roller 3, and the carding component is fixed on the first side of the comb-type waste removing knife body; fixing sleeves 4 are sleeved at both ends of the comb-type waste removing knife body, and the comb-type waste removing knife body is fixedly installed on a mechanical wallboard 5 of an external lint cleaner through the fixing sleeves at both ends.

[0032] In the prior art, after the carding component is used in a lint cleaner, since the carding component will increase the contact area between the waste removing knife and the cotton fibers, the waste removing knife needs to bear a greater impact capacity; while the existing method of welding or bolt-connecting an angle steel on the side of the waste removing knife away from the barbed roller and fixing the waste removing knife on the mechanical wallboard through the angle steel cannot meet the above-mentioned impact capacity.

[0033] In this embodiment, by sleeving fixing sleeves at both ends of the comb-type waste removing knife body, the comb-type waste removing knife body is fixed on the mechanical wallboards on both sides of the lint cleaner by using the fixing sleeves. Since the fixing sleeves are sleeved on the comb-type waste removing knife body, the fixing sleeves are in contact with the circumferential side walls of the comb-type waste removing knife body, ensuring that when the comb-type waste removing knife body is impacted in any direction, the fixing sleeves can provide effective support from the opposite direction. In the prior art, the fixing method of fixing an angle steel on the side of the comb-type waste removing knife body away from the barbed roller can only provide support for the comb-type waste removing knife body in one direction. Therefore, the method of fixing the comb-type waste removing knife body by using the fixing sleeves not only ensures the stability of the fixing of the comb-type waste removing knife body on the mechanical wallboard, ensuring the uniform stability of the gap between the comb-type waste removing knife body and the barbed roller; but also can improve the impact resistance of the comb-type waste removing knife body and can be better applied to the lint cleaner.

[0034] Example 2 The structure and principle of Example 2 are similar to those of Example 1, and the difference is that: Since the comb-type waste removing knife body is connected to the mechanical wallboard through the fixing sleeves, in order to meet the installation of the fixing sleeves, the distance between two adjacent comb-type waste removing knife bodies on the mechanical wallboard will increase, making the waste removing section larger and easily forming fallen cotton, resulting in cotton fiber loss.

[0035] Therefore, in the direction of rotation of the barbed roller, a gap adjusting component is provided at the front end, or the rear end, or both the front end and the rear end of the first side, and the gap between two adjacent comb-type waste removing knife bodies installed on the external lint cleaner is adjusted by using the gap adjusting component.

[0036] Refer to Figures 5 to 7 As shown, in Example 2, there are three structural ways of setting the gap adjusting component: First, the gap adjustment assembly includes a first gap adjustment member. The first gap adjustment member is provided at the front end of the first side, and a cutter head 6-1 is provided at the junction of the gap and the first side on the first gap adjustment member. The first gap adjustment member extends as an extension of the first side towards the front end. As shown in the figure, the first gap adjustment member adopts the structure of an additional waste removing knife 6. The additional waste removing knife is fixedly provided on the side of the comb-shaped waste removing knife body at the gap. The thickness of the additional waste removing knife is 5 mm to 10 mm. The comb-shaped waste removing knife body is made of aluminum alloy, and the additional waste removing knife is made of carbon steel.

[0037] Second, the gap adjustment assembly includes a second gap adjustment member. The second gap adjustment member is provided at the rear end of the first side, and the second gap adjustment member extends as an extension of the first side towards the rear end. The second gap adjustment assembly can adopt the structure of a cotton pressing plate 7 as shown in the figure. The cotton pressing plate includes an extended section that is an extension of the first side and a fixed section fixed on the comb-shaped waste removing knife body. The cotton pressing plate adopts the L-shaped structure as shown in the figure, or can also adopt a block structure or other structural forms.

[0038] Third, the gap adjustment assembly includes a first gap adjustment member and a second gap adjustment member. The first gap adjustment member is provided at the front end of the first side, and a cutter head is provided at the junction of the gap and the first side on the first gap adjustment member. The first gap adjustment member extends as an extension of the first side towards the front end; the second gap adjustment member is provided at the rear end of the first side, and the second gap adjustment member extends as an extension of the first side towards the rear end.

[0039] The above three structural forms of the gap adjustment assembly are selected and set according to requirements.

[0040] In "First" and "Second", a first gap adjustment member is provided at the front end of the first side of the comb-shaped waste removing knife body. As the additional waste removing knife in the figure, it can not only protect the cutting edge of the aluminum alloy comb-shaped waste removing knife, but also adjust the distance between adjacent two comb-shaped waste removing knife bodies, achieving the purpose of narrowing the waste removing section, thereby reducing the loss of cotton fibers. Or, a second gap adjustment member is provided at the rear side of the comb-shaped waste removing knife body, and the second gap adjustment member is used to separately adjust the distance between adjacent two comb-shaped waste removing knife bodies, achieving the purpose of narrowing the waste removing section, thereby reducing the loss of cotton fibers.

[0041] In "Third", due to the range limitation of the preferred thickness of the first gap adjustment member, if the first gap adjustment member provided at the front end of the first side of the comb-shaped waste removing knife body cannot meet the gap adjustment requirements of adjacent two comb-shaped waste removing knife bodies, a second gap adjustment member, such as a cotton pressing plate, is provided at the rear end of the first side of the comb-shaped waste removing knife body. Conversely, if the second gap adjustment member cannot meet the gap adjustment requirements, a first gap adjustment assembly can be added. Therefore, the gaps between adjacent two comb-shaped waste removing knife bodies installed on the external lint cleaner are jointly adjusted by the first gap adjustment member and the second gap adjustment member to prevent cotton fiber loss.

[0042] Example 3 The structure and principle of Example 3 are similar to those of Example 1 or 2. The difference is that, as shown in Figures 1 to 7 In order to meet the requirement that the comb-type waste removing knife body bends towards the barbed roller or away from the barbed roller, a set screw hole 8 is provided on the fixed sleeve or on the machine wallboard at the corresponding installation position of the fixed sleeve, and a set screw is provided in the set screw hole.

[0043] In addition, this embodiment also gives a preferred structural form of the comb-type waste removing knife body. The carding component, the additional waste removing knife, and the cotton pressing plate are arranged along the length direction of the comb-type waste removing knife body, and the lengths of all three do not exceed the distance between the fixed sleeves at both ends of the comb-type waste removing knife body.

[0044] Example 4 The structure and principle of Example 4 are similar to those of Examples 1 - 3. The difference is that the structural form of the fixed connection of the fixed sleeve on the machine wallboard is further defined, and a preferred fixing method of the fixed sleeve on the machine wallboard is given. No drawing of this embodiment is given.

[0045] In order to facilitate the installation of the fixed sleeve on the machine wallboard, a fixing hole for connecting with the external machine wallboard is provided on the fixed sleeve; a limiting hole is provided in the middle of the fixed sleeve, and both ends of the comb-type waste removing knife body are placed in the limiting hole, and the two are connected in a clearance fit and fixed by a first fastener (such as a bolt assembly).

[0046] In this embodiment, a through hole is provided on the fixed sleeve, a threaded hole is provided on the comb-type waste removing knife body. After the fixed sleeve is sleeved on the end of the comb-type waste removing knife body, the two are fixedly connected by a first fastener passing through the through hole of the fixed sleeve and the threaded hole of the comb-type waste removing knife body synchronously.

[0047] Example 5 The structure and principle of Example 5 are similar to those of Examples 1 - 3. The difference is that the structural form of the fixed connection of the fixed sleeve on the machine wallboard is further defined, and another preferred fixing method of the fixed sleeve on the machine wallboard is given.

[0048] In order to reduce the manufacturing cost of the comb-type waste removing knife body and lighten its weight, the comb-type waste removing knife body is made of aluminum alloy and is hollow inside, with an inner cavity penetrating the end face of the comb-type waste removing knife body; the thickness of the shell of the comb-type waste removing knife body is greater than 5 mm, which is used to reduce the manufacturing cost and withstand huge impact forces. The material of the fixing sleeve is carbon steel, the shell thickness is greater than 15 mm, and the shell length is greater than 40 mm; the shell thickness is greater than 15 mm in order to have a plurality of fixing holes in the horizontal direction in the fixing sleeve for connecting with the mechanical wallboard; the shell length is greater than 40 mm in order to firmly fix the fixing sleeve and the waste removing knife, with strong fixation.

[0049] If the comb-type waste removing knife body and the fixing sleeve are directly connected by bolts, based on the structure of the comb-type waste removing knife body in Embodiment 4, the bolts will often become loose, resulting in the comb-type waste removing knife body falling off the mechanical wallboard.

[0050] To solve this problem, another preferred fixing method of the fixing sleeve on the mechanical wallboard is given.

[0051] Refer to Figures 1 to 7 As shown, there are fixing holes 9 for connecting with the external mechanical wallboard on the fixing sleeve; there is a limiting hole 10 in the middle of the fixing sleeve, and both ends of the comb-type waste removing knife body are placed in the limiting hole, and the two are connected with a clearance fit; there is also a fixing block 11 arranged in the inner cavity, the fixing block is placed in the inner cavity, and the fixing block, the comb-type waste removing knife body, and the fixing sleeve are on the same vertical plane, and the three are fixedly connected by bolts.

[0052] In this embodiment, through holes are provided on the fixing sleeve and the comb-type waste removing knife body, threaded holes are provided on the fixing block, and bolts pass through the through holes on the comb-type waste removing knife body and the fixing sleeve and are screwed into the threaded holes to realize the fixed connection of the three. The fixing block and the inner cavity are provided to prevent the waste removing knife from loosening from the fixing sleeve and further firmly connect the waste removing knife shell and the fixing sleeve.

[0053] In Embodiments 1-5, a preferred structural form of the comb-type waste removing knife body is given, but the structural form of the comb-type waste removing knife body is not limited to this embodiment, and it can also adopt a triangular cross-section, quasi-triangular, and other special-shaped structures, as long as the setting of the first side and the installation of the additional waste removing knife and the pressing cotton plate are ensured. The preferred comb-type waste removing knife body is as follows: The cross-section of the comb-type waste removing knife body is in a quadrilateral structure, and it also includes a second side 2-2, a third side 2-3, and a fourth side 2-4; the additional waste removing knife is fixedly installed on the second side through a second fastener, the pressing cotton plate is fixedly installed on the fourth side through a third fastener, and the third side and the first side are on opposite sides of the comb-type waste removing knife body; The fixing sleeve is sleeved on both ends of the comb-type waste removing knife body and fits on the first side, second side, third side, and fourth side surfaces.

[0054] The present invention also provides a lint cleaner, as Figures 8-10 shown, which includes a mechanical wallboard, a barbed roller, and a plurality of the impurity removal knife mounting structures as described above. The barbed roller is rotatably connected between the mechanical wallboards; the plurality of impurity removal knife mounting structures are arranged at intervals on the outer arc surface of the barbed roller, and a working gap is left between the first side and the outer wall surface of the barbed roller; the gap between two adjacent impurity removal knife mounting structures is within the set gap range.

[0055] In the above embodiment, the structural form of the fixing sleeve is further optimized. The fixing sleeves of all the impurity removal knife mounting structures on the same side are mutually attached to each other, so that all the fixing sleeves on the same side are attached and connected to each other. The attachment and connection between adjacent fixing sleeves can, first, shorten the impurity removal section of the comb-type impurity removal knife bodies at the fixing sleeves; second, the previously installed fixing sleeve serves as a positioning component for the subsequently installed fixing sleeve, reducing the installation difficulty of the comb-type impurity removal knife bodies; third, prevent free cotton fibers from hanging at the gaps between the fixing sleeves; fourth, more impurity removal knives can be installed to improve the impurity removal efficiency of the lint cleaner.

[0056] In the above embodiment, to meet the needs of high yield, the greater the density of the needle teeth, the more impurities are removed. However, when the yield is high, the cotton fibers are easily damaged; the higher the working tooth height of the barbs on the barbed roller, the higher the fiber capacity and the higher the yield. However, the higher the fiber capacity, the less likely the impurities are to be fully combed, and the impurity removal effect is reduced. Therefore, the density of the needle teeth of the carding component does not exceed 40 teeth per square centimeter; the working tooth height of the barbs provided on the surface of the barbed roller is not less than 0.5 mm. The lint cleaner further includes a feed roller 12 provided at the inlet of the lint cleaner and a cotton fiber transfer and conveying device 13 provided at the rear of the barbed roller. The feed roller is connected to an external cotton collecting and feeding dust cage 14.

[0057] Principle explanation of the impurity removal section of the lint cleaner: The barbed roller hooks and pulls the cotton fibers to rotate. The impurities are heavier than the cotton fibers, or the impurities are small in volume and smooth on the surface and are not easily held by the barbed roller. Under the action of the centrifugal force of the barbed roller, the impurities are separated from the barbed roller prior to the cotton fibers. The function of the impurity removal knife is to support the cotton fibers and separate the impurities.

[0058] If the distance between two adjacent impurity removal knife bodies is too large, that is, the impurity removal section is too long, although the impurity removal efficiency is high, it is also easy to form falling cotton, resulting in loss of cotton fibers.

[0059] Taking a specific comb-type waste removing knife body as an example; during operation, the bottom carding component combs and blocks the cotton fibers pulled by the barbed roller, making it easier for impurities to separate from the cotton fibers. At the same time, compared with traditional waste removing knives, the cotton fibers are more likely to separate from the barbed roller. Therefore, the comb-type lint cleaner needs to set a waste removing section smaller than that of the traditional lint cleaner; generally, the waste removing section of the comb-type lint cleaner is about 15 mm (such as half of the 30 mm long cotton fibers); the traditional waste removing section is generally about 30 mm.

[0060] However: In order to have multiple horizontal fixing holes in the fixing sleeve, taking the hole diameter of 13 mm as an example, the thickness around the fixing sleeve should be greater than 15 mm. After the waste removing knife is installed through the fixing sleeve, the waste removing section formed between two waste removing knives is 30 mm (15 mm in front of the knife + 15 mm behind the knife), which greatly exceeds the waste removing section of about 15 mm of the comb-type lint cleaner. During operation, a large amount of effective cotton fibers will be lost.

[0061] Therefore: As a remedial measure, along the direction of rotation of the barbed roller, in the front part of the first side of the comb-type waste removing knife body, between the two fixing sleeves, install an additional waste removing knife made of carbon steel with a thickness of 5 mm to 10 mm; further, in the rear part of the first side of the comb-type waste removing knife body, between the two fixing sleeves, install a cotton pressing plate; through the combined action of the additional waste removing knife and the cotton pressing plate, the waste removing section reaches about 15 mm within the normal range, achieving both waste removal and no cotton dropping.

[0062] The above is only the preferred embodiment of the present invention and does not impose any form of limitation on the present invention; any ordinary technician in the industry can smoothly implement the present invention according to the instructions shown in the accompanying drawings and the above description; however, any minor changes, modifications, and equivalent variations made by those familiar with the technology in the technical scope of the present invention without departing from the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications, and variations made to the above embodiments based on the essence of the present invention still fall within the protection scope of the technical solution of the present invention.
