Description

Technical Field

[0001] This utility model belongs to the field of textile machinery manufacturing technology, and relates to the improvement of carding machines, specifically a carding machine combing device and a carding machine. Background Technology

[0002] The carding machine is a crucial part of the cotton spinning process. Its preceding process is the opening and cleaning machine, and its subsequent process is the drawing frame. It is mainly used to card pure cotton, chemical fibers, and their blends. The raw material is fed into the cotton box, and through a series of mechanical actions, the crimped cotton fibers are carded into a basically straight fiber state, and impurities are removed, finally forming a sliver for use in subsequent spinning processes.

[0003] With rising labor costs, machine-harvested cotton is gradually replacing manual harvesting. However, machine harvesting inevitably introduces impurities such as leaves, straw, and film, resulting in a higher impurity content in the fibers. Processing machine-harvested cotton increases the weight burden on semi-finished products and yarns, leading to a relatively high waste rate and increased cotton consumption. Due to the higher impurity content in machine-harvested cotton, these impurities easily become embedded in the carding fabric during carding, resulting in poor web clarity. Therefore, higher requirements are placed on the impurity removal performance of carding machines when processing machine-harvested cotton.

[0004] Existing carding machines mainly include a feeding device, flats, cylinder, doffer, licker-in roller, and carding unit. The carding unit has pre-carding capability to remove impurities. The carding unit mainly includes a carding plate cover, a cotton support plate, a carding plate rack, a limiting shaft, an adjusting tongue, and a carding plate base. The main functions and existing problems of existing carding units are as follows:

[0005] 1. The cotton support plate installed at one end of the combing plate cover can ensure the sealing of the fiber channel while adjusting the length of the first impurity zone; however, it is a two-piece assembly structure with the combing plate cover, and there is a gap between the two, which makes it easy for cotton to get caught; in addition, due to the structural changes of the combing plate cover, it is inconvenient to install and fix the cotton support plate on the side of the combing plate cover.

[0006] 2. The adjustable tongue plate designed in the fiber outlet direction of the carding device can rotate and be manually adjusted to adjust the length of the second impurity drop zone, thereby controlling the cotton loss rate and impurity removal effect. However, since the adjustable tongue plate is manually adjusted, the operation is inconvenient and the adjustment accuracy is not high.

[0007] 3. The aluminum profile of the combing device is prone to deformation when heated, which may sometimes cause problems with the needles connecting to the barn roller.

[0008] Therefore, there is an urgent need in this field to design a combing device for a combing machine to solve the above-mentioned problems and shortcomings in the existing technology. Utility Model Content

[0009] To address the aforementioned problems in the prior art, this utility model provides a combing machine combing device with a reasonable structural design that prevents fraying, facilitates smoother airflow, and solves the problem of inconvenient installation and fixing on one side of the combing plate cover.

[0010] The objective of this utility model is achieved through the following technical solution:

[0011] A carding machine's carding device includes a frame, a carding plate cover, a carding plate rack, a carding plate base, an adjusting tongue, an adjusting pointer, a scale plate, and a control system.

The scale plate is located near the adjusting pointer and mounted on the frame. The device is characterized in that a cotton-supporting plate is provided on one side of the carding plate cover, and the cotton-supporting plate and the carding plate cover are an integral structure.

[0012] Improvement to the above technical solution: A first dust removal knife holder is set near the cotton support plate. The first dust removal knife holder is in the shape of a "7". A first dust removal knife is set on one side of the first dust removal knife holder. The upper part of the first dust removal knife holder overlaps one end of the cotton support plate. A second dust removal knife is set near the free end of the adjusting tongue plate.

[0013] Further improvement to the above technical solution: A regulating tongue plate motor drives the rotating shaft to rotate through a transmission mechanism. The control system is connected to the control terminal of the regulating tongue plate motor to control the regulating tongue plate motor to rotate forward or backward, thereby driving the regulating tongue plate and the regulating pointer to rotate counterclockwise or clockwise by a certain angle, in order to accurately control the appropriate amount of cotton waste.

[0014] Further improvements to the above technical solution: The rack mounting seat is installed on the comb plate base, and the rack mounting seat and the comb plate base are fixedly connected as a whole by multiple screws. The comb plate rack is installed on the rack mounting seat, and the side of the rack mounting seat is provided with a threaded hole, into which a long screw is screwed.

[0015] Further improvements to the above technical solution: An adjusting bolt is provided at each end of the comb plate base, passing through the through hole on the comb plate base and the comb plate outer cover. The head of the adjusting bolt is inserted into the T-slot of the rack mounting seat. The combination of the comb plate base and the rack mounting seat is restricted within the comb plate outer cover by the locking nut. A pressure spring is provided on each side of the comb plate base. The pressure spring is sleeved on the adjusting bolt and located between the comb plate outer cover and the rack mounting seat.

[0016] Further improvements to the above technical solution: The drive mechanism includes a synchronous pulley I, a synchronous belt, and a synchronous pulley II. The synchronous pulley I is mounted on the transmission shaft of the adjusting tongue motor, and the synchronous pulley II is mounted on the rotating shaft. The synchronous belt is sleeved on the synchronous pulley I and the synchronous pulley II.

[0017] Further improvement to the above technical solution: The top surface of the adjusting tongue plate is a smooth and clean surface, and a wear-resistant layer is covered on the top surface.

[0018] A carding machine includes a licker-in roller and a carding device, characterized in that the carding device is the carding device described above.

[0019] Compared with the prior art, this utility model has the following advantages and positive effects:

[0020] (1) The combing plate cover and the cotton support plate of this utility model are designed as an integral unit. The structure is reasonable. The cotton support plate and the combing plate cover are an integral structure.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] See Figures 1-4 This utility model discloses an embodiment of a carding machine's carding device, comprising a frame, a carding plate cover 1, a carding plate rack 2, a carding plate base 5, an adjusting tongue 4, an adjusting pointer, a scale plate, and a control system. One end of the adjusting tongue 4 is rotatably connected to one side of the carding plate cover 1 via a rotating shaft 15. The adjusting pointer is fixed on the rotating shaft 15. The scale plate is located near the adjusting pointer and mounted on the frame. A cotton-supporting plate 1.1 is provided on the other side of the carding plate cover 1, and the cotton-supporting plate 1.1 and the carding plate cover 1 are integrally formed. There are no gaps between the cotton-supporting plate and the carding plate cover, making it less prone to snagging and allowing for smoother airflow. This solves the problem of inconvenient installation and fixation on one side of the carding plate cover.

[0031] Furthermore, a first dust removal knife seat 10 is provided near the cotton support plate 1.1. The first dust removal knife seat 10 is in the shape of a "7". A first dust removal knife 9 is provided on one side of the first dust removal knife seat 10. The upper part of the first dust removal knife seat 10 overlaps one end of the cotton support plate 1.1. A second dust removal knife 11 is provided near the free end of the adjusting tongue plate 4.

[0032] like Figure 1 As shown, the carding machine separating device of the present invention is located below the carding machine licker-in roller, and also includes a feeding plate 8. The area between the feeding plate 8 and the first dust removal knife 9 is the first impurity removal zone S1; the area between the adjusting tongue plate 4 and the second dust removal knife 11 is the second impurity removal zone S2. The above are all prior art, so they will not be described in detail.

[0033] Furthermore, an adjusting tongue plate motor 12 drives the rotating shaft 15 to rotate via a reduction gear transmission mechanism, and the aforementioned control system is connected to the control terminal of the adjusting tongue plate motor 12. In this way, by adjusting the tongue plate motor 12 to rotate forward or reverse, the control system drives the adjusting tongue plate 4 and the adjusting pointer to rotate counterclockwise or clockwise by a certain angle, which can precisely control the appropriate amount of cotton dropping and achieve rapid and accurate adjustment of the angle of the adjusting tongue plate 4.

[0034] Furthermore, a rack mounting seat 3 is installed on the aforementioned comb plate base 5. The rack mounting seat and the comb plate base are fixedly connected as a whole by multiple screws. The comb plate rack 2 is installed on the rack mounting seat 3. Threaded holes A and B are provided on the side of the rack mounting seat 3. A long screw is screwed into each of the threaded holes A and B, which increases the rigidity of the comb plate base 5, making it less prone to heat deformation and preventing the problem of needle contact with the licker roller.

[0035] Furthermore, multiple adjusting bolts are passed through the through holes in the carding plate outer cover 1 and the carding plate base 5. The heads of the adjusting bolts are inserted into the T-slots of the rack mounting seat 3. The combination of the carding plate base 5 and the rack mounting seat 3 is constrained within the carding plate outer cover 1 by locking nuts. A pressure spring 6 is installed on each side of the carding plate base, and the pressure spring 6 is sleeved on the adjusting bolts and located between the carding plate outer cover 1 and the rack mounting seat 3. Compared with the previous fixed spacing, when the fiber layer 7 is too thick, the fiber layer 7 squeezes the carding plate base away from the licker-in roller, compressing the pressure spring 6. The spacing between the carding machine's carding device and the licker-in roller increases, preventing damage to the licker-in roller card cloth and the carding machine's carding device. When the thickness of the fiber layer 7 returns to normal, the pressure spring 6 resets, and the carding plate base 5 resets under the elastic force of the pressure spring 6. The spacing between the carding machine's carding device and the licker-in roller returns to the original set value. The pressure spring 6 can protect the combing plate toothed rack 2 and the licker-in roller needle cloth, preventing damage.

[0036] Preferably, the top surface of the adjusting tongue plate 4 is a smooth and clean surface, and a wear-resistant layer is covered on the top surface. This can improve the hardness and wear resistance of the aluminum profile.

[0037] Specifically: the aforementioned adjusting tongue motor 12 is a stepper motor, and the aforementioned drive mechanism includes a synchronous pulley I 13, a synchronous belt 14, and a synchronous pulley II 16. The synchronous pulley I 13 is provided on the drive shaft of the adjusting tongue motor 12, and the synchronous pulley II 16 is provided on the rotating shaft 15. The synchronous belt 14 is fitted on the synchronous pulley I 13 and the synchronous pulley II 16.

[0038] See Figures 1-4 An embodiment of the carding machine of the present invention includes a licker-in roller and a carding device, wherein the carding device is a carding machine carding device of the above embodiment.

[0039] The working principle of the combing machine's combing device of this utility model:

[0040] When the carding machine is working, the fiber layer 7, as it passes under the licker-in roller, first enters the cotton support plate 1.1 at one end of the carding plate outer cover 1. After entering, the fibers are carried into the carding plate rack 2 by the high-speed rotation of the licker-in roller. As the cotton flow passes through, the cotton support plate 1.1 and the carding plate outer cover 1 are an integral structure without gaps or splices, resulting in smoother and more stable airflow and preventing cotton snagging. The pressure springs 6 at both ends of the carding plate base 5 are connected to the carding plate base 5 by bolts. During initial equipment installation, the elasticity and spacing of the pressure springs 6 can be adjusted by rotating the bolts. When the fiber layer 7 enters the carding area, if the fiber layer 7 is too thick, it will press the carding device downwards, compressing the pressure springs 6. When the normal thickness of the fiber layer 7 is less than the initial spacing, the pressure springs 6 reset, restoring the initial spacing. The pressure springs 6 play a protective role, preventing accidents caused by excessively thick fiber layers 7 damaging the carding cloth or carding parts. After passing through the combing plate rack 2, the fiber layer 7 enters the adjusting tongue plate 4. The adjusting tongue plate 4 can be driven by an adjusting tongue plate motor 12 to adjust the rotation angle, thereby adjusting the size of the second impurity drop zone length S2 and precisely controlling the impurity drop and removal effect of the carding machine.

[0041] Compared with existing technologies, the combing device of this utility model can meet the market demands of different users. The adjusting tongue plate 4 can be adjusted manually or electrically, which can satisfy the process requirements of different users for different raw materials.

[0042] Of course, the above description is not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
