Abstract

Disclosed is a carding machine, which comprises a carding part composed of several carding elements, a feeding part, a delivering part and a driving part. Two adjacent rollers in a carding element form a carding group. One of the two rollers is a high speed roller, and the other is a low speed roller. The high speed roller of one carding group is adjacent to the low speed roller of another carding group. Two rollers of every carding group shift between a fast rotating speed and a slow rotating speed periodically and synchronously, and the speed of the high speed roller is always higher than the speed of the low speed roller. When a carding group shifts from the slow rotating speed to the fast rotating speed, the adjacent carding group shifts from the fast rotating speed to the slow rotating speed. When a carding group shifts from the fast rotating speed to the slow rotating speed, the speed of the high speed roller becomes lower than the speed of the low speed roller in the adjacent carding group.

Description

A carding machine

The present invention generally relates to textile material preparation techniques, and more particularly to a carding machine having a high production efficiency for damage to the length of the pile fibers during the carding process. Background technique

Patent document CN100335693C discloses a carding method which uses two adjacent rolls of variable speed stripping and combing, and when one of the rolls is rotated at a high speed, the other roll is rotated at a low speed. The high-speed roller strips the low-speed roller, then the high-speed roller decreases the speed to the low-speed roller, the low-speed roller increases the speed to the high-speed roller, and the high-speed roller strips the low-speed roller, so that the stripping is repeated to achieve the carding . One of the rolls or two rolls is also reciprocated while shifting, and the fibers are transferred from one section of the roll to the other. The carding section combines the feeding device and the outlet device to complete the entire carding process. Such a technique can achieve a lint-free condition in the case of significantly reducing fiber damage as compared to the carding of the squeezing roller and the combing of the carding ring. The ratio of the linear velocity of the adjacent two rolls at the time of stripping is positively correlated with the combing efficiency, that is, the higher the speed ratio, the higher the combing efficiency, and the smaller the speed ratio, the lower the combing efficiency. The high combing efficiency means that the machine has a strong ability to remove coarse wool and impurities. On the contrary, the combing efficiency is low, and the machine has a weak ability to remove coarse hair and impurities. When the adjacent two-roller stripping stripping is used, one roller runs from a low speed to a high speed in one operating cycle, and the other roller goes from a high speed to a low speed. As long as the surface linear velocity of one roll is slightly larger than the surface linear velocity of the other roll, the stripping action can occur. Moreover, the stripping can usually be completed when the speed ratio is not changed much. At this time, even if the speed ratio is increased, the stripped roller has no fiber to be stripped, and the stripping of the stripping can only result in the combing. The inefficiency of the treatment. This phenomenon can be alleviated by increasing the rotational speed and the rate of change, but the problem of low combing efficiency cannot be fundamentally solved. In the specific implementation, only the number of stripping and stripping can be increased to obtain the required lint-free. This leads to low productivity. Pending patent application 2009100219713 (filed on April 13, 2009) A method of using a plurality of opening rollers is proposed. However, this method still has the above problems.

Those skilled in the art can understand that the specific embodiments described below are to be considered as illustrative and illustrative and not restrictive. The carding machine of the present invention comprises: a carding portion composed of a carding roller and utilizing a ratio of surface line speeds between adjacent carding rollers to realize fiber carding; and a material for conveying the material to the carding portion a feeding portion; an outlet portion of the target fiber for separating the carding portion; and a driving portion for driving the carding portion to operate in a predetermined motion mode. The carding section may comprise a number of carding units. Each of the carding units includes a plurality of cylindrical opening rollers arranged adjacently along a plane. The carding roller is a known component conventionally used in the art. The opening roller is formed by enclosing an elastic card clothing with a cylinder. A steel needle is arranged on the elastic card clothing. One end of the steel needle is fixed to the base fabric for wrapping the roller, and the other end is oriented at an angle to the diameter of the roller. The plurality of opening rollers of the carding unit are sequentially adjacently arranged in a plane along the diameter direction of the roller section. The plane is referred to as the arrangement plane of the carding unit. That is to say, the axis of each of the opening rollers in the carding unit is a set of parallel lines on the arrangement plane of the carding unit. The maximum distance between the surface of the opening roller and the plane of the arrangement is the radius of the roller (section). During the operation of the carding unit, under the drive of the drive mechanism, the rollers are rotationally rotated about their axes in a set motion mode. The adjacent two opening rollers in the carding unit rotate in opposite directions. The direction of the steel needle on each roller (referred to as the needle direction) - coincides with the direction of rotation of the roller. This arrangement is known in the art as "needle-wise phase stripping." Adjacent lines along the axial direction of the adjacent two opening rollers are referred to as stripping lines. The stripping line is a virtual line, in fact, there is a certain gap between adjacent rolls. For two adjacent opening rollers, a roller having a higher surface speed will strip the fibers attached to the roller having a lower surface speed. In the following, when referring to the peeling of the fibers attached to the ethylene roll by the nail roll, it may be simply referred to as "a roll peeling of the ethylene roll". For two adjacent opening rollers, the surface speed of the nail roll divided by the surface speed of the ethylene roll is equal to the speed ratio. Since the rotation directions of the two adjacent opening rollers are opposite, the adjacent two opening rollers are separated from the stripping line by 90 degrees along the circumference of the section of the opening roller along the circumference of the section of the opening roller. The section is referred to as a turn-out zone, and the section shifted by 90 degrees against the rotation direction of the roller on the other side of the arrangement plane is referred to as a turn-in zone. Both the transfer zone and the rollout zone include a quarter arc of the two rollers. From the cross-section of the opening roller, the two end points of the transfer zone correspond to the farthest points of the two opening rollers on the corresponding side of the arrangement plane, and the two end points of the transfer zone correspond to the two ends respectively. The individual combing rollers are at the farthest point on the other side of the arrangement plane. The midpoints of the transfer zone and the transfer zone correspond to the tangent points of the two carding rollers. A turn-in area adjacent to the adjacent opening roller may be provided with a straight cylindrical guide tube in the axial direction of the opening roller. A fixed cover can be mounted on the guide tube. For the construction and function of the draft tube and the fixed cover, reference is made to the relevant content of the patent application of the applicant's application No. 2009100219713. A carding machine according to the present invention comprises: a carding portion composed of a carding unit; a feeding portion for conveying the fluff to the carding portion; and an outlet portion for separating the carding portion a cashmere-free transfer machine; a driving portion for driving the carding unit to operate in accordance with a predetermined motion mode. The plurality of rollers of the carding unit are sequentially adjacently arranged along their arrangement planes. When the carding unit is in operation, the steering of each roller is the same as the needle direction, the adjacent rollers are turned to the opposite direction, and the needles are smoothly stripped between adjacent rollers. These features are consistent with traditional techniques. According to an embodiment of the invention, each of the two adjacent rollers in the carding unit constitutes a carding group, one is a high speed roller and the other is a low speed roller, and, for two adjacent carding groups, one carding group The high speed rolls are adjacent to the low speed rolls in the other carding group, or the low speed rolls in one carding group are adjacent to the high speed rolls in the other carding group. The carding unit operates in a predetermined mode under the driving of the driving mechanism, wherein: the two rollers of each carding group are periodically synchronized from a low speed to a high speed and then from a high speed to a low speed, and the two rollers Maintaining the set speed ratio; when a carding group changes from low speed to high speed, its adjacent carding group changes from high speed to low speed; when a carding group changes from high speed to low speed, The surface linear velocity of the high speed roller becomes lower than the surface linear velocity of the low speed roller of the adjacent carding group; and when a carding group is changed from a low speed to a high speed, the surface speed of the low speed roller becomes higher than the adjacent carding group The surface speed of the high speed roller. For the carding unit, a plurality of rollers are arranged adjacent to each other in sequence, and are sequentially divided into two, and each two adjacent rollers constitute one carding group. In operation, one of the two rollers of the same carding group is low The speed roller and the other are high speed rollers. The two rollers of each carding group are synchronously shifted, and "in-phase" shifting, that is, when one roller changes from low speed to high speed, the other roller also changes from low speed to high speed, when one roller changes from high speed to low speed. At the time of the rotation speed, the other roller also changes from the high speed to the low speed, and the speed ratio of the two rollers can be a set value. For each carding group, when it is not at the edge, the high speed roller is adjacent to the low speed roller in an adjacent carding group, wherein the low speed roller is adjacent to the high speed roller in another adjacent carding group. The carding group at the edge, or the high speed roller therein is adjacent to the low speed roller in an adjacent carding group, or the low speed roller therein is adjacent to the high speed roller in an adjacent carding group. The shifting phases of adjacent combing groups are reversed, that is, when a carding group is changed from a low speed to a high speed, the adjacent carding group is changed from a high speed to a low speed, and vice versa. The high speed roller in the first carding group obtains the fiber and begins to reduce the rotational speed, while the adjacent second carding group begins to increase the rotational speed when the surface linear velocity of the high speed roller in the first carding group is lower than in the second grooming group. At the surface linear velocity of the low speed roll, the fibers of the high speed roll in the first carding group are transferred to the high speed rolls in the second carding group by the low speed rolls in the second carding group. Similarly, the high speed roller in the second carding group obtains the fiber and begins to reduce the rotational speed, while the adjacent third carding group begins to increase the rotational speed, when the surface linear velocity of the second carding group's high speed roller is lower than the third combing When the surface speed of the set of low speed rolls is reached, the fibers of the high speed rolls in the second carding group are transferred to the high speed rolls in the third carding group by the low speed rolls in the third carding group. The sequential carding groups are then oriented in the same manner for the stripping transfer. Each two adjacent rolls constitute a carding group. The two rolls in each carding group are synchronously shifted in phase, and the ratio of the surface linear velocity of the two rolls can be a set value. The set value can be as large as possible, if the mechanical state permits. When the surface speed of the low speed rolls of one carding group is lower than the surface speed of the high speed rolls of the adjacent carding group, the low speed rolls will be free of fibers. When the surface linear velocity of the low speed roller of the carding group is higher than the surface linear velocity of the adjacent carding group high speed roller, the low speed roller peels the fibers of the adjacent carding group high speed roller and transfers to the high speed roller of the carding group. When the low speed rolls of one carding group strip the fibers of the adjacent carding group high speed rolls and transfer to the high speed rolls of the carding group, the order of the surface linear speeds of the respective carding rolls of the two carding groups is: The highest, the low speed roller of this group determines that the speed ratio is lower than the high speed roller of the group and slightly higher than the high speed roller of the adjacent carding group, and the low speed roller of the adjacent carding group is the lowest. Thus, according to the method of the present invention, for two adjacent carding groups, stripping and combing is achieved by a three-stage speed ratio. The carding unit can arrange 8 to 16 carding groups. The specific number of carding groups can be determined according to the type of fiber to be processed and the quality requirements. The diameters of the high speed roller and the low speed roller in one carding group may be the same or different. When not the same, the diameter of the high speed roller should be larger than the diameter of the low speed roller, so that the high speed roller can accommodate more fibers, thereby increasing the output of the machine. The carding unit is disposed near the turn-in section of the adjacent carding roller in the axial direction of the opening roller to provide a straight-shaped guide tube. A fixed cover can be mounted on the guide tube. According to a preferred embodiment of the present invention, the arrangement plane of the carding unit is parallel to the ground, and the turning-out area of the low-speed roller and the high-speed roller of each carding group of the carding unit faces the ground, that is, the low speed of each carding group The roll-out area of the roll and the high speed roll is located below the arrangement plane. According to the method of the present invention, when the surface linear velocity of the low speed roller is slightly higher than the surface linear velocity of the high speed roller of the adjacent carding group, the stripping action can occur, the carding efficiency is low, and the main function is to transfer; The speed ratio between the low speed roller and the high speed roller is set to a large value. When the low speed roller has fibers and is stripped by the high speed roller, the two rollers are stripped at a high speed and large speed ratio, and the main function is to separate the comb; The advantage of less fiber damage during the split combing is that the efficiency of stripping and combing is significantly improved, and the ability of the machine to remove coarse hair and impurities is significantly improved, thereby significantly increasing the output of the machine and reducing the production cost. The respective opening rollers of the carding unit are driven by a drive mechanism. The drive mechanism includes a control device, a power transmission device, and a non-circular gear train to realize acceleration, deceleration, and the like of each of the opening rollers. This makes the carding unit work in the above-mentioned operating mode. The fiber stripping transfer of the opening roller of the present invention is a directional transfer, which can be arranged with reference to the feeding portion, the pre-carding portion, the carding portion, the sorting machine portion and the driving portion of the conventional carding machine. The specially constructed drive portion allows the carding portion to operate in accordance with the aforementioned mode of operation. The production procedure according to the present invention is: After the washing and velvet are opened and the machine is opened, the feeding machine is put into the feeding machine to quantitatively and evenly feed; and then the feeding roller, the opening roller, the chestwood, the transfer roller, the large Xilin, The doffer performs pre-combing; then transfer to the carding part by the transfer roller, each carding group is provided with a fixed cover plate and a guiding tube, and the turning-out area of the low-speed roller and the high-speed roller of each carding group is facing the ground to facilitate roughing Miscellaneous; then through the transfer roller, the second large Xilin, the second doffer, the sickle, the cashmere box sorted out. The carding machine has a simple structure and a high output, and is suitable for use as a production. Although the present invention has been described with reference to the specific embodiments thereof, various modifications, modifications and substitutions of the present invention will be apparent to those skilled in the art without departing from the scope and spirit of the invention. It is obvious.
