Description

Technical Field

[0001] This utility model relates to the field of drawing frame technology, specifically a drawing frame cleaning device. Background Technology

[0002] As a crucial piece of equipment in the textile industry, the drawing frame is widely used in the carding, blending, and sliver forming processes of fiber materials. In actual production, the working environment of the drawing frame often generates a large amount of fiber debris, dust, and other impurities. If these impurities are not cleaned in a timely manner, they will not only affect the normal operation of the equipment but may also lead to a decline in product quality, even causing equipment failure and increasing maintenance costs. However, existing drawing frame cleaning devices have many shortcomings in design and technical implementation. On the one hand, traditional cleaning methods rely heavily on manual operation, which is inefficient and cannot guarantee thorough cleaning. On the other hand, while some automated cleaning devices can achieve a certain degree of cleaning, their complex structure, inconvenient operation, and limited cleaning effect are particularly poor when dealing with fine fiber debris and highly adhesive impurities. Furthermore, existing cleaning devices often lack effective water resource management and recycling mechanisms during the cleaning process, leading to resource waste and environmental pollution. Simultaneously, the internal drying process after cleaning is not efficient enough, easily resulting in residual moisture that can affect subsequent production. Therefore, there is an urgent need for a drawing frame cleaning device that is structurally sound, easy to operate, and clean and efficient, in order to solve the above problems and meet the needs of modern textile industry for high-efficiency and high-quality production. Utility Model Content

[0003] This utility model relates to a cleaning device for drawing frames, aiming to solve the problems of low cleaning efficiency, complex equipment structure, and insufficient reliability in the existing technology. Therefore, this utility model proposes a drawing frame cleaning device with a reasonable structure and complete functions.

[0004] This utility model provides a cleaning device for a drawing frame, including a base plate, a machine housing, a box, a cleaning system, a transmission system, and a yarn guiding system. Wherein:

[0005] The base plate serves as the fundamental support for the entire device, upon which a housing is fixed with screws. The housing protects the internal components, ensuring the safety and stability of the equipment's operation. Furthermore, a box-like structure is housed within the housing to accommodate and protect the internal cleaning components. A drain pipe is fixedly connected to one side of the box-like structure via a flange. This drain pipe is designed as a straight pipe, with one end connected to the interior of the box and the other end extending to the outside, used to drain wastewater after cleaning, preventing water accumulation and damage to the equipment.

[0006] Furthermore, a support plate is fixed to the bottom wall of the housing, and a top plate is fixed to the top of the support plate with hexagonal bolts. One end of the top plate is fixedly connected to the top of the housing, forming a stable overall frame structure. The connection between the support plate and the top plate is fastened with bolts, which facilitates disassembly and maintenance, while also enhancing the rigidity of the overall structure.

[0007] Specifically, the cleaning system includes a water tank, hoses, square tubes, and nozzles. A water tank is fixedly installed on the top of the housing; its volume is set according to actual usage requirements and is used to store cleaning water. The water tank is connected to four symmetrically arranged square tubes on the top of the support plate via four hoses. One end of each hose extends into the square tube, delivering the cleaning fluid to the nozzles. Four arrays of three nozzles are fixedly installed on the bottom of the support plate. The nozzle inlets are fixedly connected to the corresponding square tubes for spraying cleaning fluid onto the areas requiring cleaning. The water spraying function of the nozzles is achieved by a water pump with an output pressure range of 0.2 MPa to 0.5 MPa to meet different cleaning needs.

[0008] Furthermore, the transmission system includes a motor, a rotating shaft, a crank, a connecting rod, and a sliding plate. A motor is fixedly mounted on the bottom of the support plate, and the motor's output end is connected to the rotating shaft via a coupling. The rotating shaft is fixedly connected to the crank by screws, one end of which is movably hinged to a connecting rod, and the other end of which is movably hinged to a sliding plate. A dryer is fixedly mounted on the bottom of the sliding plate for drying the washed yarn. A rectangular slot is formed through the support plate, and the sliding plate slidably connects to the rectangular slot, thereby realizing the reciprocating motion of the sliding plate. The reciprocating stroke range of the sliding plate is 100mm to 300mm, and the specific stroke can be adjusted by adjusting the length of the crank.

[0009] Specifically, the yarn guiding system includes a yarn guiding bracket and yarn guiding rollers. The yarn guiding bracket is fixed to the bottom wall of the support plate, and several yarn guiding rollers are installed on the yarn guiding bracket to guide the yarn smoothly through the cleaning area. There are six yarn guiding rollers, evenly distributed on the yarn guiding bracket, with a center-to-center distance of 50mm between adjacent rollers. The yarn guiding rollers work in conjunction with the spinning rollers to ensure that the yarn maintains uniform tension during the cleaning process, avoiding poor cleaning results or yarn damage due to uneven tension.

[0010] Furthermore, the coordinated operation of the cleaning system and the transmission system is as follows: S1, after the motor is started, the motor drives the rotating shaft to rotate, and the rotating shaft drives the sliding plate to reciprocate through the crank and connecting rod; S2, the dryer at the bottom of the sliding plate moves accordingly to dry the cleaned yarn; S3, the water tank delivers cleaning liquid to the square tube through the hose, and the nozzle sprays the cleaning liquid onto the yarn to complete the cleaning process; S4, the wastewater after cleaning is discharged through the drain pipe to ensure that the inside of the equipment is dry and clean.

[0011] Specifically, the nozzle has a spray angle range of 30° to 60° and a spray distance of 100mm to 200mm to ensure that the cleaning fluid can accurately cover the areas that need cleaning. Furthermore, the spray pressure of the nozzle is controlled by a water pump with a flow rate range of 5L / min to 10L / min to meet the cleaning needs of yarns of different materials.

[0012] Furthermore, the reciprocating motion frequency of the sliding plate ranges from 1Hz to 2Hz, with the specific frequency determined by the motor's rotational speed. The motion trajectory of the sliding plate is determined by the geometric relationship between the crank and the connecting rod, ensuring that the sliding plate can slide smoothly within the rectangular slot and avoiding jamming.

[0013] Specifically, the surface of the yarn guide roller is coated with a polytetrafluoroethylene (PTFE) coating to reduce friction between the yarn and the roller, preventing damage to the yarn during the washing process. The diameter of the yarn guide roller ranges from 20mm to 30mm, with the specific size selected according to the yarn thickness.

[0014] Furthermore, a filter device is installed at the outlet end of the drain pipe. The filter device consists of multiple layers of stainless steel mesh, used to intercept impurities carried in the wastewater and prevent clogging of the drain pipe. The mesh size of the filter device ranges from 50 to 100 mesh, and the specific mesh size is selected according to the particle size of the impurities in the wastewater.

[0015] Specifically, the top of the water tank is equipped with a water inlet with a diameter of 20mm, used to replenish the water tank with cleaning water. A level gauge with a range of 0L to 50L is installed on the side wall of the water tank for real-time monitoring of the water level in the tank.

[0016] Furthermore, the heating element of the dryer is a ceramic heating element with a power range of 200W to 500W to meet the drying needs of different yarns. The outlet temperature of the dryer ranges from 50℃ to 80℃, and the specific temperature is adjusted by a temperature controller.

[0017] Specifically, the bottom of the base plate is provided with an anti-slip pad, which is made of rubber material and is 5mm thick, to enhance the stability of the device and prevent slippage during operation.

[0018] Through the above technical solutions, this utility model achieves the following technical effects: The cleaning system, through the combined design of a water tank, hose, square tube, and nozzle, can accurately spray the cleaning liquid onto the areas requiring cleaning, significantly improving the uniformity of the cleaning effect. The transmission system, through the coordinated work of a motor, rotating shaft, crank, connecting rod, and sliding plate, realizes the reciprocating motion of the dryer, completing the automated operation of cleaning and drying. The yarn guiding system, through the reasonable layout of the yarn guiding rollers, ensures uniform yarn tension during the cleaning process, avoiding poor cleaning effect or yarn damage. The design of the drain pipe effectively removes wastewater after cleaning, avoiding water waste and environmental pollution.

[0019] In summary, this utility model provides a drawing frame cleaning device with a reasonable structure and complete functions. It has the technical characteristics of high-efficiency cleaning, high degree of automation, stable and reliable structure, and energy saving and environmental protection, and is suitable for cleaning operations of various yarns.
