Description

Technical Field

[0001] This utility model relates to the field of textile machinery and equipment technology, specifically a carding machine feeding structure with adjustable thickness. Background Technology

[0002] During the conveying process, cotton material is transported through a feeding assembly. The feeding assembly forms a relatively narrow channel, which enables the initial shaping and limiting of the cotton material, forming a near-sheet-like state. It can then be fed more smoothly into the carding machine, where the cotton material undergoes further shaping and carding. The stability and adjustment precision of the feeding structure directly affect the uniformity of the cotton layer and the subsequent spinning quality.

[0003] The existing feeding gap is mostly adjusted manually by screws or shims, which requires machine shutdown and the adjustment range is difficult to control precisely. Especially when switching between different fiber raw materials (such as cotton, linen, and chemical fibers) or producing products of different specifications, frequent adjustments can easily lead to production interruptions. In addition, due to human operation errors, the cotton layer thickness often exceeds the process requirement of ±0.5mm, requiring repeated adjustments and affecting efficiency. Utility Model Content

Detailed Implementation

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0024] like Figure 1-4 As shown, a carding machine feeding structure with adjustable thickness includes a feeding housing 1 and a feeding housing 2 disposed at the end of the feeding housing 1. The feeding housing 1 is used to receive materials and perform preliminary processing and thickness adjustment, while the feeding housing 2 conveys the material with adjusted thickness to subsequent processes of the carding machine. An adjustment component is provided inside the feeding housing 1.

[0025] Adjustment Components: The adjustment components include a fixed roller 3, a movable roller 4, and a traction roller 5. The fixed roller 3 is rotatably mounted on the inner wall of the feeding housing 1, forming a transition gap between itself and the bottom end of the inner wall of the feeding housing 1, through which the material is initially flattened. The movable roller 4 forms an adjustable feeding gap with the bottom end of the inner wall of the feeding housing 1. By changing the position of the movable roller 4, the size of the feeding gap can be changed, thereby adjusting the thickness of the material conveying. The fixed roller 3, movable roller 4, and traction roller 5 are connected by a conveyor belt 6. A drive motor 7 is installed outside the feeding housing 1 to provide power to the entire transmission system, driving the fixed roller 3 and movable roller 4 to rotate synchronously, enabling the material to be stably conveyed on the conveyor belt 6.

[0026] Anti-slip design: The outer surfaces of the fixed roller 3 and the movable roller 4 are circumferentially distributed with anti-slip patterns 17, and the inner wall of the conveyor belt 6 is provided with anti-slip teeth 18 that cooperate with the anti-slip patterns 17. This cooperative design of anti-slip patterns 17 and anti-slip teeth 18 greatly increases the friction between the conveyor belt 6 and the rollers, preventing slippage during conveying and ensuring the stability of material conveying. The outer surface of the conveyor belt 6 is provided with anti-slip protrusions 19, and the anti-slip protrusions 19 are rounded. The anti-slip protrusions 19 can increase the friction between the belt and the material, allowing the material to move better with the belt, while the rounded corners avoid damage to the material.

[0027] Drive assembly: A drive assembly is provided between the traction roller 5 and the movable roller 4 to drive the movable roller 4 to move vertically, thereby changing the distance between the movable roller 4 and the bottom of the inner wall of the feed housing 1. The drive assembly includes a fixed block 8 fixedly installed on the inner wall of the feed housing 1. An electric telescopic rod 9 is fixedly connected to the fixed block 8. A pulley 10 is rotatably installed at the output end of the electric telescopic rod 9, and the pulley 10 is in contact with the movable roller 4. When the electric telescopic rod 9 extends or retracts, the pulley 10 rolls on the movable roller 4, pushing the movable roller 4 to rise or fall vertically, thereby adjusting the feeding gap.

[0028] Guide structure: Both ends of the movable roller 4 are rotatably connected to sliders 11. The inner wall of the feed housing 1 is symmetrically provided with grooves 12 that slide in cooperation with the sliders 11, and the sliders 11 are located inside the grooves 12. The slider 11-groove 12 structure provides guidance for the vertical movement of the movable roller 4, ensuring that the movable roller 4 remains stable during movement, avoiding deviation, and ensuring the accuracy of the feeding gap adjustment.

[0029] The slide bar 13 passes through the through hole 20 of the fixed block 8, and the two ends of the spring 14 abut against the fixed block 8 and the traction roller 5, with an initial preload of 50N. When the belt loosens due to wear or vibration, the spring 14 pushes the traction roller 5 to automatically tension (tensioning stroke ±3mm), while absorbing more than 80% of the vibration energy to ensure the stability of the movable roller 4.

[0030] Feeding channel: A needle roller 15 is rotatably mounted inside the feeding housing 2, and a rotary motor 16 is installed on the feeding housing 2 to drive the needle roller 15 to rotate. A feeding channel is formed between the needle roller 15 and the bottom end of the inner wall of the feeding housing 2. After the material has passed through the feeding housing 1 and its thickness has been adjusted, it enters the subsequent process of the carding machine through this feeding channel. The rotation of the needle roller 15 can further comb and convey the material.

[0031] Working principle:

[0032] Power input and transmission start:

[0033] When the drive motor 7 starts, it drives the fixed roller 3 to rotate clockwise. Through belt transmission, the movable roller 4 rotates counterclockwise and the traction roller 5 rotates clockwise, forming a stable conveying power (the belt linear speed is controlled in real time by the motor speed).

[0034] Fiber feeding and initial spreading:

[0035] The fiber falls from the front end of the feed housing 1. When it passes through the transition gap (6mm) between the fixed roller 3 and the bottom of the inner wall, it is driven forward by the anti-slip protrusions 19 of the fixed roller 3. Under the action of belt friction, it is initially flattened into a loose layer with a thickness of H0=10mm.

[0036] Precise thickness adjustment:

[0037] The electric telescopic rod 9 adjusts the height of the movable roller 4 according to process requirements. For example, if H is set to 3mm, the movable roller 4 rises to reduce the feeding gap. When the fiber layer passes through, it is squeezed into a sheet with a uniform thickness of 3mm. At the same time, the anti-slip texture 17 of the movable roller 4 cooperates with the belt to generate a backward pulling force to ensure that the fiber layer does not accumulate.

[0038] Buffering, vibration reduction, and stable conveying:

[0039] During the conveying process, if the belt tension changes abruptly due to impurities in the fibers, the traction roller 5 moves backward by compressing the spring 14 through the slide bar 13, automatically tensioning the belt; at the same time, the spring 14 absorbs vibration energy, maintains the stable position of the movable roller 4, and ensures that the H value is constant.

[0040] Needle roller 15 combing and output:

[0041] A 3mm thick fiber sheet enters the feeding housing 2, and the needle roller 15 rotates and combs it from a sheet shape into a fluffy cotton layer (the thickness expands to 3.5mm). It is then output to the carding machine cylinder through the feeding channel, completing the feeding process.
