Description

Card machine needle board

The invention relates to a needle plate for a carding machine. One of the main components in the carding process is the needle plate and its pattern of hairpins that provide an important role in the carding function. In particular, the invention relates to the direction of the hairpin of the card body of the card. In particular, the invention relates to a modified board having a hair raising needle for a carding machine.

The spinning process involves cleaning and removing impurities present in the fibers, straightening (ie, placing the fibers in parallel) and then fiber bundles in the textile yarn. The cleaning and straightening of the fibers is mainly done on the first two processing machines, namely the cleaning room and the carding machine. The carding process involves extensive cleaning of the impurities in the fiber mixture and the separation of the fibers to individual extents. In order to help separate the fibers to almost individual extent in the card, the main carding action takes place between a roller called a carding roller and a plate covered with a hairpin or serration, depending on the need, the carding roller Raised needles of various sizes and shapes. These rollers and rods also run very close and at different surface speeds. The card shows the card. The main working rollers and the rods are mentioned in Figure 1. An enlarged view of the rotary plate is shown in the drawings. The carding machine mainly has three rollers known as the licker roller 1, the main roller 2, and the doffer shown in the drawings. There are some rods known as flat knit bars that are mounted on the main drum and act on an endless path around a portion of the main drum. All three of the rollers are provided with serrated raising pins in a tightly packed coil such that the raised teeth extend radially over their surface. The flat knit bar is covered with the top of the plate shown in the enlarged scale and is known as a "rotary plate". The top of the plate includes an elastic base on which the different types of cross-section of the raised needle fibers, ie elliptical, oval or flat, are pressed. The end of the hair raising needle projecting from the elastic base is bent in an intended direction so as to be opposite to that on the main roller of the movement of the rotary plate. The tip of the raising needle is ground at the top and sides to create a sharp raised needle point. The tops of these panels are mounted on flat knit bars known as "bald boards". The rotator plate is covered with a fine burr point at the top of the plate. Based on the action between the two sets of raised needle points, the relative orientation of the raised needle points on the different components, in particular the rollers, is provided. As shown in Fig. 1, the direction of the raising point in the licker roller and the drum is the same. Therefore, it performs the stripping action. The point of the raising pin in the main roller and the top of the plate is reversed. Therefore, it performs a carding action. In order to perform a good carding action, it is preferred that the drum should be rotated at a high speed, i.e., at a high surface speed, while the rotating plate is moved at a lower surface speed.

When the material is fed to the card, first the licker rolls in the roller take small tufts of fibers from the feed roller. These small clusters of fibers are transferred by stripping action to the main drum coated with finer hairpin points. The fiber clusters are therefore distributed over a higher number of raised needle points to aid in the intense carding action between the main roller and the point of the top of the plate. The fiber transfer from the licker roll to the drum depends on various factors such as the angle of the hair point, the relative surface speed of the two components and, most importantly, the gap/gauge between the two draping surfaces. The uniformity of the gap between the drum and the licker roller 6, between the drum and the top 5 of the panel, and between the drum and the doffer 7 is critical and important to achieve good and consistent performance of the card. In addition, the direction of the raising pin at the top of the plate is also very important, as the main carding action takes place between the carding roller and the top of the plate. It is well known in the textile industry that carding is the center of spinning. The high yield in the carding saves the process leading to a reduction in yarn quality. The purpose of carding is to open the fiber clusters into individual fibers, to clean or eliminate impurities, to reduce cotton (tangled fibers), to eliminate dust, to eliminate short fibers, to mix fibers, to align or straighten fibers, to form slivers. Therefore, it is very important that the carding roller and the card clothing on the top of the board. In existing systems, all 80 to 110 panels are provided with a one-way card clothing. Due to this configuration of the card clothing at the top of the board, the carding action is unsatisfactory. This is a major drawback of the carding action. In an improved system, the raising pins of the plate are not unidirectional.

Purpose of the invention

A primary object of the present invention is to remove the above disadvantages.

A further object is to change the direction of the raising pins of the card clothing as needed to perform a uniform carding.

A further objective is to alternately place the top of the board by changing the direction of the card clothing at the top of the board.

Another purpose is to maintain the carding action evenly.

Another purpose is to create more uniform slivers.

These and other advantages of the present invention will be immediately apparent from the following detailed description. Summary of invention

The summary of the invention is presented below to provide a basic understanding of some aspects of the invention. This summary of the invention is not an extensive overview of the invention. It is not intended to identify key/critical elements of the invention or to describe the scope of the invention. The sole purpose of the invention is to be considered in a

According to an aspect of the present invention, there is provided a card comprising: (a) a main carding roller having a roller shaft and carrying a roller clothing on a peripheral surface thereof; the roller clothing having a card clothing point; (b) a action board that cooperates with the main carding drum along a length portion thereof; the action board includes (1) a plurality of flat knit bars, each having a flat knit bar clothing cooperating with the drum clothing; the flat type a knit bar clothing having a card clothing dot; and (2) a driving device for co-moving the flat knit bar in an endless path, having a working leg and a return leg where the flat knit bar clothing cooperates with the roller clothing The working foot extends around a portion of the primary carding drum; wherein each of the plurality of flat knit bars has a different helical direction of the alternating card clothing to deflect the fibers from one direction to the other.

Other aspects, advantages, and salient features of the invention will become apparent to those skilled in the <

A depth analysis of all the operating elements of the carding element with regard to the influence on the carding properties has been carried out. It has been found that the "roller plate" area is clearly the most effective area for the card to perform the following actions. 1. In order to open the fiber cluster into individual fibers 2. Cleaning or eliminating impurities 3. Reduction of cotton (tangled fibers) 4. Elimination of dust 5. Elimination of short fibers 6. Fiber mixing 7. Fiber direction or school Straight 8. Cotton sliver formation (carding machine output material)

According to the carding theory, it is possible to unravel 75% of all cotton granules and in fact unlock about 60% of these. Of the remaining 40%, 30-33% of the unbondable cotton particles are transferred with the sliver, 5-6% are removed with the slats, and the remaining 2-4% are eliminated along with the waste.

The main job of the card is to separate the individual fibers, which are performed between the main drum and the plates. It is only possible to remove fine dust particles and dust by separating this fiber.

The improved pattern of the top wiring of the board is in the left to right direction. Traditional system:

Depending on the structure of the card, each card will have 80-110 number of rotating plate tops. The point of raising the needle in the top of the plate is set in such a way as to create a flow path like a canal, so that the individualized fibers will follow that path. In general, any material flow will try to take the simplest path to flow easily.

When the hairpin point is only in one direction, the fiber will always flow in one direction - for example in the right spiral direction, the carding action is limited by the unidirectional fiber flow. The fibers are thus transferred in the gap and will not be further effectively combed. Moreover, in a conventional configuration, the fibers are maintained in one direction within a few top movements. The other tops will be in the idle state. The fibers in the unidirectional flow are shown in Figure 2. So the fiber will not be effectively combed. The proposed system:

In this new configuration, in the top of the next entry action, by reconfiguring the needle in this second top, the canal path is turned in the opposite direction - assuming a left helix. The fiber flow is dispersed/twisted and aids in further bonding. It is expected that the fiber bundle will be loosened and separated into many paths.

Again, the third top will enter the action and turn to the fiber flow in the right helix direction. This steering will continue to occur during the carding process (in such a way that the fibers are deflected from one direction to the other during the carding).

Due to the change in the helical pattern of the clothing, the fibers are deflected from at least one of the plates to the next.

The direction of the fibers is changed from a plurality of plate tops to a plurality of plate tops having different spirals. Preferably, two plates having a spiral direction are placed after two plates having different directions of spirals on the top of the plate, so that The flow of the fibers is changed after every two plates.

The helix angle of the hair stylus changes between 0 degrees and 89 degrees helix, which is provided in a card clothing having a top of the sawtooth plate or having a plate pilling needle.

In the new configuration, in each of the tops, there will be tension on the fibers during their contact with the serrations of the card cylinder. Fibers flowing in two directions are shown in Figure 3.

The detailed composition of the card is shown in Figure 1. The carding process involves extensive cleaning of the impurities in the fiber mixture and the separation of the fibers to individual extents. In order to help separate the fibers to almost individual extents, the rollers and the sticks in the card are covered with card clothing, which includes fluffing teeth of various sizes and shapes as desired. These rollers and rods also operate at very close distances and at different surface speeds. A schematic side view of the card is shown in Figure 1. The main working roller and the rod are shown in Figure 5. In Fig. 5, there is an enlarged view of the rotary plate. The card mainly has three rollers known as the licker roller 1, the main roller 2, and the doffer 4 shown in Fig. 1. There are some rods known as flat knit sticks 5 that are mounted on the main drum and act on an endless path around a portion of the main drum. All three rollers are provided with a serrated raising needle in a tightly packed coil such that the raising teeth extend radially over their surface. The flat knit bar is covered with an elastic hair raising needle made of a steel needle 3 as shown by an enlarged scale in Fig. 5, and is known as a "rotary plate". The top of the plate includes an elastic base on which different types of cross-sections (ie, elliptical, oval or flat) are pushed into the elastic base. The end of the raised needle projecting from the resilient base is bent in an intended manner such that it opposes the movement on the main drum of the rotating plate. The tip of the raising needle is ground at the top and sides to create a sharp raised needle point. The tops of these panels are mounted on flat knit bars known as "bald boards". The rotator plate is covered with a fine burr point at the top of the plate. It is also possible that the flat knit rod is clamped with a metal top (ie, a serrated raising needle) rather than an elastic raising needle. Based on the action between the two sets of raised needle points, the relative orientation of the raised needle points on the different components, in particular the rollers, is provided. As shown in Fig. 1, the direction of the raising point in the licker roller and the drum is the same. Therefore, it performs the stripping action. The point of the raising pin in the main roller and the top of the plate is reversed. Therefore, it performs a carding action. In order to perform a good carding action, it is preferred that the drum should be rotated at a high speed, i.e., at a high surface speed, while the rotating plate is moved at a lower surface speed.

When the material is fed to the card, first the licker rolls in the roller take small tufts of fibers from the feed roller. These small clusters of fibers are transferred by stripping action to the main drum coated with finer hairpin points. The fiber clusters are thus distributed over a higher number of raised needle points to assist in the intensive carding action between the main roller and the point of the top of the plate. The fiber transfer from the licker roll to the drum depends on various factors such as the angle of the hair point, the relative surface speed of the two components and, most importantly, the gap/gauge between the two draping surfaces. The uniformity of the gap between the drum and the licker, between the drum and the top 5 of the drum, and between the drum and the doffer 7 is critical and important to achieve good and consistent performance of the card.

A conventional panel configuration is shown in Figure 2, in which all of the panels are provided with raised teeth in the same direction. Due to such a configuration, the fibers of the carded between the drum and the plate are transferred by the pen line without any turning to create tension on the fiber bundle to provide a further opportunity for the carding.

An improved plate structure is shown in Figure 3, in which plates having serrations of different orientations are placed alternately so that the fibers are deflected from one direction to the other, whereby the fibers are stretched for better carding and The same is shown in Figure 3.

Details of the plate hairpin and the drum sawtooth have been shown in Figure 4. It shows the carding action between the plate and the main drum, wherein the wheeled plate is covered with a hair raising needle and the drum is covered with serrations. The plate rotates counterclockwise and the drum rotates clockwise.

The complete unit of the panel is shown in Figure 5. Approximately 80 to 120 such plates are combined in a chain and rotated on the drum so that the raising pins of the two are disposed at close distances. Advantage:

The reinforcing fibers can be separated from the drum to the top of the plate.
