Description

Technical Field

[0001] The utility model relates to the technical field of spinning preparatory machines, and particularly relates to a carding machine cleaning device for a conveying assembly in a textile carding machine. Background Technique

[0002] Textile spinning preparatory machines include carding machines, combers, draw frames, etc. Among them, the carding machine is the most important one. Carding is the core of spinning, and the main goal of the carding machine is to separate the fiber mass into individual fibers. In addition, carding can flatten the fibers, reduce neps, align, mix, eliminate some short fibers, and form a sliver. By using cards, the fiber mass is reduced to individual fibers and formed into a thin film-like web by operating between the surfaces of two closely spaced and oppositely pointed wire points. This is the most effective method of opening and cleaning a fiber mass of a few milligrams into almost single fibers.

[0003] Carding is a mechanical process that opens, removes trash and neps, breaks down fiber masses and irregular lumps, and then aligns the individual fibers so that they are more or less parallel to each other. Finally, the mixed and fluffy textile material is converted into a soft, un-twisted string in the form of a fine sliver. The fiber mat fed into the carding machine should be highly uniform to ensure consistent opening and carding.

[0004] The fibers opened and cleaned by the licker-in system are transferred to the main cylinder by the peeling action. The fibers peeled from the licker-in by the main cylinder are transferred to the carding zone, that is, the area between the main cylinder and the flat plate. In principle, when the wire points on the two surfaces are inclined in opposite directions, the carding action is completed. When determining the carding action, the movement direction and movement rate of point-to-point are crucial. The rotating flat plate is a metal wire rod that rotates around the main cylinder rotating at a high speed at a very slow speed. The entire circumference of the main cylinder is provided with wire points for processing fiber materials.

[0005] The fibers coming out of the carding zone form a very thin web. This web is extracted from the main cylinder by another device called the doffer cylinder. The significant reduction in the surface speed of the doffer cylinder compared to the surface speed of the main cylinder results in a condensation effect on the fiber web. The fiber web is peeled from the doffer cylinder by the stripping roller. Then, it passes through a pair of squeezing rollers, and finally it is stacked into a fiber bundle shape. The fiber web from the squeezing rollers is collected by a pair of conveyor belts and transferred to the calender rollers. The calender rollers compress the fiber bundle to provide better integrity and stable material flow. The fiber bundle or sliver travels upward on the guide pulley and enters the winding device. The winding unit includes a trumpet-shaped guide and a second pair of calender rollers, which convey the carded sliver into the carded sliver can through a rotating tube.

[0006] To facilitate the transportation and collection of the fiber web, various additional forms of devices have been proposed. According to these suggestions, the transmission of the fiber web is promoted by an air flow or a conveyor belt, and these belts run along the direction of the fiber web or perpendicular to the direction of the fiber web. It has also been proposed to use a fiber web guide plate or roller, which laterally guides the fiber web and presses it together, enabling the transportation of the fiber web even at high speeds.

[0007] When collecting the fiber web from the extrusion roller, due to the adhesiveness of the conveyor belt surface, some fibers will accumulate on the conveyor belt. This fiber accumulation will cause the fiber web to break after a period of time. In turn, it may also affect the quality of the final sliver.

[0008] Therefore, a cleaning device for a carding machine is needed, which ensures the quality of the sliver and the safety of the operator, thereby overcoming the limitations and disadvantages existing in existing machines. Summary of the Utility Model

[0009] To solve the above technical problems, the present utility model provides a cleaning device for a carding machine, which can prevent fiber accumulation and sliver breakage in the carding machine and ensure the safety of the operator.

[0010] The technical solution of the present utility model is as follows:

[0011] A cleaning device for a carding machine, comprising a conveying assembly; the conveying assembly is configured to collect the fiber web from the extrusion roller, and the conveying assembly includes a mounting frame and a conveyor belt group disposed on the mounting frame, characterized in that at least one fiber stripping blade is provided on the mounting frame, and each fiber stripping blade is disposed parallel to the driving direction of the conveyor belt group; a sealing cover is further provided on each fiber stripping blade.

[0012] Further, the conveyor belt group includes a pair of conveyor belts oppositely disposed on the mounting frame, and on the mounting frame, and at each end of each conveyor belt away from each other, a fiber stripping blade is provided, and the front end surface of each fiber stripping blade is joined to the outer surface of its corresponding conveyor belt.

[0013] Further, each sealing cover is an open box-shaped body, and its opening faces the conveyor belt. An accommodation chamber is provided inside each sealing cover. The side of each fiber stripping blade away from the conveyor belt is connected to the side of each sealing cover, and the end of the conveyor belt facing the sealing cover is within the range of the accommodation chamber of the sealing cover.

[0014] Further, an adaptation gap is provided between the accommodation chamber of each sealing cover and the outer surface of its corresponding conveyor belt.

[0015] Further, each fiber stripping blade and the sealing cover are an integrally formed module structure.

[0016] Further, each of the fiber stripping blades is a polymer material blade or an elastic blade.

[0017] Further, a fiber stripping blade driving device is also provided on the mounting bracket. The driving end of the fiber stripping blade driving device is connected to the fiber stripping blade to drive it to approach or move away from the outer surface of the conveyor belt group.

[0018] Further, the fiber stripping blade driving device includes a pneumatic driver, a hydraulic driver, a solenoid driver, and an electric driver.

[0019] The beneficial technical effects of the present utility model are as follows:

[0020] The present utility model uses fiber stripping blades to strip the fibers accumulated on the surface of the conveyor belt. On the one hand, since a sealing cover is provided to install the fiber stripping blades, the fibers in the stripping area can be prevented from flying. At the same time, it also avoids the stripped fibers from flowing with the collected fiber web. On the other hand, since the fiber stripping blades and the sealing cover are fixed together as a single module, the installation and disassembly of this module are simplified.

[0021] In addition, the combination of the sealing cover and the fiber stripping blades also provides safety protection for both sides of the machine. This reduces the possibility of accidents when the machine operator approaches the web collection area during maintenance operations. The sealing cover also forms a uniform gap between the end and the conveyor belt by providing a radially inner surface, thereby eliminating the accumulation of flying fibers.

Detailed Embodiments

[0026] In order to be able to more clearly understand the technical means of the present utility model and implement it in accordance with the content of the specification, the following combines the drawings and embodiments to further describe the detailed embodiments of the present utility model in detail. The following embodiments are used to illustrate the present utility model but are not used to limit the scope of the present utility model.

[0027] As Figure 1As shown in the figure, the fiber web mass from the bale opener is fed into the carding machine 2 through the chute assembly 1. The fed fiber web mass is cleaned, refined, and paralleled in the carding machine 2. First, the supplied fiber web mass passes through the supply plate area 3 and then reaches the licker-in in the licker-in area 4. Then, the fiber web mass passes between the main cylinder 5 and the rotating flat plate assembly 6, where carding is performed. The doffer 7 is arranged downstream of the main cylinder 5. The doffer receives the opened fiber web from the main cylinder 5 and conveys the fiber web through the deflector roller 8 and the fiber web guide plate (not shown). After the fiber web is guided through a pair of squeezing rollers 9, the fiber web is collected by the calender roller and the conveying assembly, and then is compressed into a sliver form by passing it through a compressor. Subsequently, the compressed sliver is stored in a sliver can through a winding device. As Figures 2 - 3 shown, the present utility model provides a carding machine cleaning device, which is applied to the cleaning of the conveying assembly in the above-mentioned textile carding machine.

[0028] The conveying assembly of the present utility model includes a mounting frame 13 and a conveyor belt group arranged on the mounting frame. The conveyor belt group of the present utility model includes a pair of conveyor belts 10, which are respectively arranged between the driving wheel and the driven pulley mounted on the mounting frame 13. The pair of conveyor belts 10 are respectively driven by the driving wheel and the driven wheel to rotate. When the fiber web is conveyed and collected from the gap between the two conveyor belts 10, some fibers will accumulate on the conveyor belts 10 and stick to the surface of the conveyor belts 10, resulting in the rupture of the conveyed fiber web after a period of time. For this reason, in the present utility model, on the mounting frame 13 and at both ends where the two conveyor belts 10 are away from each other, that is, at the left and right ends of the mounting frame 13, a fiber stripping blade 11 is provided at each end.

[0029] Each fiber stripping blade 11 is a long strip rectangular piece, which is arranged parallel to the conveyor belt driving direction, and the cutting edge part of the front end face of each fiber stripping blade 11 is in contact with the outer surface of the corresponding conveyor belt 10. When the two conveyor belts 10 operate in cooperation, due to the relative movement, the fiber stripping blade 11 on each conveyor belt 10 scrapes the fibers or dust sticking to the conveyor belt 10 in the direction opposite to the running direction of the conveyor belt 10. That is, when the conveyor belt 10 on the left side of the mounting frame 13 rotates counterclockwise from left to right, and when the conveyor belt 10 on the right side of the mounting frame 13 rotates counterclockwise from right to left, the fiber stripping blade 11 on the left side of the mounting frame 13 intercepts and scrapes the fibers or dust on its corresponding conveyor belt 10 to the left, and the fiber stripping blade 11 on the right side of the mounting frame 13 intercepts and scrapes the fibers or dust on its corresponding conveyor belt 10 to the right.

[0030] Preferably, each fiber stripping blade 11 is made of a polymer material, or made of other elastic materials, elastomers or the like.

[0031] To prevent the scraped fiber debris or dust from flying or flowing with the running and collecting fiber web, a sealing cover 12 is also provided on each fiber stripping blade 11.

[0032] The sealing cover 12 of the present utility model is a box-shaped body with an opening in the shape of a rectangle, composed of two top plates, two side edges and a back plate, and has a receiving space. The opening of each sealing cover 12 faces the conveyor belt. One side edge of each fiber stripping blade 11 away from the conveyor belt 10 is connected to one side edge of a sealing cover 12, and the end of the conveyor belt 10 is located within the distance between the two side edges of its corresponding sealing cover 12, so that the scraped fiber debris or dust can be located within the receiving space of the sealing cover 12. Further, a suitable uniform gap is also provided between the outer surface of each sealing cover 12 and the end of its corresponding conveyor belt 10, so that the fiber debris or dust in the receiving space of the sealing cover 12 can be sucked away by the turning roller 8 under the action of pipeline suction, avoiding accumulation. Among them, the above-mentioned fiber debris or dust can be sucked away by the turning roller 8 under the action of pipeline suction, which is the prior art and will not be elaborated here.

[0033] Preferably, each sealing cover 12 and the fiber stripping blade 11 can be integrally formed or used as a whole module to be fixed, so as to simplify the installation and disassembly of the module.

[0034] In addition, the combined design of the sealing cover 12 and the fiber stripping blade 11 also provides safety protection for both sides of the machine, which reduces the possibility of accidents when the machine operator approaches the fiber web collection area during maintenance operations.

[0035] Preferably, the present utility model also provides a scraper driving device (not shown) for periodically driving the cleaning device of the present utility model to remove the accumulated fiber debris from the surface of the conveyor belt 10. The connection and driving of the scraper driving device and the cleaning device are the prior art and will not be elaborated here. For example, the fixed end of the above-mentioned scraper driving device is arranged on the mounting frame 13, and its driving end is connected to the fiber stripping blade 11 to drive the fiber stripping blade 11 to approach or move away from the surface of the conveyor belt 10 to remove the accumulated fiber debris.

[0036] The scraper driving device can be selected as pneumatic, hydraulic, solenoid tube, electric or other driving devices according to needs.

[0037] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
