Description

Fabric weaving snatchs edulcoration device after unpacking with fibre

Technical Field

The invention relates to the technical field of textile processing, in particular to a device for grabbing and removing impurities after unpacking fibers for fabric weaving.

Background

The spinning process generally includes the processes of unsealing the fiber package, and obtaining the spooled yarn through processes of cotton grabbing, cotton opening, cotton mixing, carding, drawing, roving, spun yarn and the like. Partial process also comprises yarn steaming and the like. The initial process of cotton grabbing as fiber yarn formation mainly comprises the steps of loosening compressed fiber blocks into fiber bundles by fibers in a fiber bag through a cotton grabbing beater or a cotton grabbing roller, grabbing the fiber bundles, and blowing away the grabbed fibers to the next procedure through an exhaust pipe under the action of a fan.

Prior art bale pluckers typically have a reciprocating bale plucker and a disc bale plucker, respectively, depending on the manner in which the fibers are gripped. The working principle of the efficient reciprocating bale plucker is that fibers are pre-laid in a strip-shaped cotton box, and the fibers are dispersedly grabbed through the linear reciprocating motion of a bale plucking mechanism. Disc type plucker like that disclosed in patent application 201921913812.X is a disc type plucker for spinning, and its theory of operation is to lay the fibre in advance in the circular cotton box, through the circular motion of plucking mechanism, realize the dispersion of fibre and snatch.

The prior art has the following technical problems in the prior art that the bale plucker dispersedly snatchs the fiber bundles:

firstly, because fibers in a fiber bag, such as a cotton bag, contain a large amount of cottonseeds, dust, metal particles and other impurities, the fibers need to be removed in each process before spinning and forming so as to avoid influencing evenness of yarn, generating mechanical collision and even causing fire; therefore, impurity removal processes exist in all the working procedures of cotton picking, cotton opening and picking, cotton mixing, carding and the like; in the cotton grabbing process, the impurity removal of the fibers mainly falls on the removal of metal particles in the fibers, for example, a beating hand of a reciprocating cotton grabbing machine with a strong magnetic iron roller disclosed in patent application 201310119993.X, a metal separation device on a grabbing arm of the reciprocating cotton grabbing machine disclosed in patent application 201910487583.8, and the impurity removal device such as a magnet is integrated on the cotton grabbing mechanism to adsorb the magnetic metal particles mixed in the fibers. However, other impurities such as cotton seeds and dust cannot be removed well, and thus, the workload of impurity removal in the subsequent process is increased. Patent application 201820294. X discloses a cotton opening impurity removal machine, though blow in the edulcoration case through the inside cotton of hair-dryer with defeated cotton passageway, send into the cotton feed roller through defeated cotton roller with the cotton that blows in, when cotton feed roller is rotatory for cotton, arrange impurity roller together rotatory take away the cotton surface's that the cotton feed roller carried impurity and fall into in arranging impurity passageway through the third filter screen, carry out getting rid of other impurity on fibre surface, but this cotton feed roller, what parts such as row impurity roller actually formed is opening the scutching mechanism, equivalent to will open clear and grab cotton and integrated, and can not carry out getting rid of other impurity in grabbing the cotton stage.

Secondly, because the fibre piles up in the hopper, grab cotton mechanism and often open the fibre piece of upper strata only and snatch, along with the reduction of upper fibre piece height, can influence the efficiency of snatching of grabbing cotton mechanism, the mode of prior art's mode one adoption grabbing cotton mechanism lift activity is grabbed the reduction of cotton mechanism height and is satisfied the fibre piece contact with the upper strata, a disc bale plucker as patent application 201710398784.1 discloses, the disc bale plucker that patent application 201920354858.6 disclosed, through dispose elevating system alone on grabbing cotton mechanism, drive through the elevating system motion and grab cotton mechanism elevating movement. This approach suffers from the following disadvantages: if a proximity switch (infrared probe) is adopted for automatic control, the production cost of the whole machine is high, the subsequent maintenance cost is high, and the fibers are scattered, so that the false judgment of the proximity switch is caused; in addition, the horizontal movement (reciprocating linear movement or circular movement) of the cotton grabbing mechanism of the whole machine and the horizontal movement lifting movement of the cotton grabbing mechanism need to be controlled independently, which can cause troublesome regulation and control. The second mode is the disc type plucker disclosed in patent 201310737879.3, which changes the deformation of the compression spring by supporting the spring under the chassis and changing the gravity of the cotton fiber borne by the spring, so that the cotton fiber to be combed can be automatically lifted to adapt to the height of the plucker beater, and the following disadvantages exist in this mode: the spring is continuously pressed, and the elastic coefficient change is influenced by the repeated deformation, so that the resilience accuracy is low; the stability of the chassis in the ascending motion and the non-motion state is improved only by the support of the spring.

Its third, prior art's plucker is at the plucking in-process, and the angle tooth that only relies on the plucking beater carries out opening, snatching of fibre piece more, when fibre piece compactedness is higher, opens and snatchs efficiency value gliding to leading to the plucking beater, influences work efficiency.

Secondly, the invention forms a plurality of sub-bins through the partition board isolation, thus the fiber jittering accumulated in the annular cotton storage bin is differentiated, namely different screen meshes drive the fiber blocks in different areas to jitter, on one hand, the independent jittering of the fiber blocks in different areas can be realized, the fiber blocks on each screen mesh can jitter from place to place, on the other hand, the technical problems of poor control stability and poor impurity removal and dispersion efficiency caused by the integral synchronous jittering of all the fiber blocks are avoided.

Because still be provided with the round baffle in the outside of first ring groove, utilize the effect of baffle, can further prevent to open the probability that the flying cotton fibre that snatchs the in-process production falls into to annular installation storehouse inside through first ring groove.

Furthermore, the fiber block is opened in advance through the fiber pre-opening device, so that the efficiency of opening and grabbing cotton by a follow-up grabbing cotton beater can be improved. The invention realizes the mechanical cooperation of the revolution of the fiber pre-opening device around the rotating shaft and the rotation of the fiber pre-opening device, and compared with the connection of a motor at the end part of the fiber pre-opening device, the invention further saves power sources and further improves the operation convenience of the whole machine.

The turret 5 penetrates through a central hole of the chassis 11 from top to bottom, partition plates 15 are arranged on the chassis 11, and two adjacent partition plates 15 are distributed at intervals, preferably at equal angles. The peripheral plate 13 surrounds the periphery of the base plate 11, and a sub-bin with an open top is formed between two adjacent partition plates 15, the peripheral plate 13, the base plate 11 and the turret 5. A screen 12 which can move up and down is slidably fitted in the sub-bin. The screen driving device 14 is used for driving the screen 12 to move up and down.

Of course, the present invention realizes that the rotating shaft 51 rotates for a plurality of turns to drive the transition gear 651 to rotate for one turn by changing the outer diameter of each gear, so that the incomplete gear 652 is meshed with the auxiliary gear 64 once, and the auxiliary gear 64 rotates for a plurality of turns.

In the process that the rotating shaft 51 rotates forwards for one circle, the cotton grabbing mechanism 2 completes one circle of rotation around the central axis of the annular cotton storage bin, and completes one circle of opening and cotton grabbing of the upper fiber blocks in the annular cotton storage bin. In the initial stage of the process, the rotating shaft 51 rotates to drive the main gear 63 to rotate, the main gear 63 rotates to drive the transition gear 651 to rotate, the transition rotating shaft 653 rotates to drive the incomplete gear 652 to rotate, the toothed section of the incomplete gear 652 is not meshed with the auxiliary gear 64, the non-toothed section, namely the outer convex arc section of the incomplete gear 652 is matched with the inner concave arc of the tooth part of the auxiliary gear 64, the incomplete gear 652 rotates and the auxiliary gear 64 is locked relatively, when the main gear 63 rotates to be close to a circle, specifically 270-350 degrees, the incomplete gear 652 rotates to be meshed with the auxiliary gear 64, the incomplete gear 652 rotates to be a complete section of the toothed section to complete the rotation of the auxiliary gear 64 for several circles, and the connecting block 62 is driven to complete one-time ascending motion.

Therefore, the intermittent adjustment of the rotation opening cotton grabbing of the cotton grabbing mechanism 2 and the ascending of the screen 12 is realized, namely the time period of the ascending of the screen 12 can be concentrated in the time period of the rotation to the set time period of the cotton grabbing mechanism 2, and the height of the fiber block on the screen 12 is kept unchanged in most of time except the factor of height floating caused by shaking.

As shown in fig. 9, in some embodiments, in particular, the output shaft of the screen driving motor 145 is linked with the screen driving shaft 141 by the first belt conveyor. The first belt transmission device comprises a first belt wheel 1461 fixed on an output shaft of the screen mesh driving motor, a second belt wheel 1462 fixed on the screen mesh driving rotating shaft 141, and a first belt sleeved on the first belt wheel and the second belt wheel.

According to the invention, the screen driving motor is started to drive the screen driving rotating shaft 141 in transmission fit with the screen driving motor to rotate, and the two conical gears 144 matched with each other are used for reversing transmission to drive the other screen driving rotating shaft 141 to rotate, so that in linkage, each screen driving rotating shaft 141 is driven to rotate, the cam 142 in each lower bin body is driven to rotate, and when the cam 142 rotates until the protruding section of the cam is contacted with the bottom of the screen 12, the screen 12 is driven to shake.

By adopting the structure of the screen driving device 14, the cams 142 in each lower bin body are linked, and compared with the mode that one screen driving motor is configured on the screen driving rotating shaft 141 of each lower bin body, the screen driving device can realize the movement of all the cams 142 by actually controlling one screen driving motor. If a mode that one screen driving motor is configured on the screen driving rotating shaft 141 of each lower bin body is adopted, the other end of the screen driving rotating shaft 141 does not need to extend into the adjacent lower bin body, and the bevel gear 144 does not need to be arranged at the two ends of each screen driving rotating shaft 141.

In some embodiments, when cam 142 has a circular arc, screen 12 is relatively stationary when cam 142 has a circular arc in contact with the bottom of screen 12. The screen 12 is intermittently moved up and down and shaken every time the screen driving shaft 141 rotates one turn.

In some embodiments, at the same time, the rotation states of the cams 142 in the lower bin bodies are different, for example, when two cams 142 in two adjacent lower bin bodies rotate until the top point of the protruding section contacts with the bottom of the corresponding screen 12, that is, when the screen 12 shakes to the top point, the cam 142 in the second bin body rotates until the circular arc section contacts with the bottom of the corresponding screen 12, that is, the screen 12 shakes to the bottom point, or when the cam 142 in the second bin body rotates until the non-top point of the protruding section contacts with the bottom of the corresponding screen 12, that is, the screen 12 shakes to the non-top point. Thereby effecting the fiber masses on each screen 12 to dither in this pitch. In this way, in the initial stage of the present invention, a small height difference exists between the top surfaces of the screens 12, for example, the distance between the top point and the bottom point of the movement of the screens 12 can be controlled to be 1-5 cm according to the size of the cam 142. Since the amplitude of the shaking of the screens 12 is small, the top surface of each screen 12 can be set at an initial stage to be approximately flush with the top surface of each partition 15. Of course, the present invention can also realize the synchronous movement of all the screens 12 in the same way of the rotation state of the cams 142 in each lower bin body.

In some embodiments, the mounting base 143 is fixed to the top of the chassis 11.

In some embodiments, two screen driving shafts 141 are arranged in parallel in the same lower bin, and the two screen driving shafts 141 in the same lower bin are linked by a second belt conveyor. That is, a third belt wheel (not shown) is fixed on each of the two screen driving shafts 141, and a second belt is sleeved between the two third belt wheels in the same lower bin body.

Compared with the prior art, the device for grabbing and removing impurities after unpacking the fibers for fabric weaving has the following advantages: firstly, the gripping and impurity removing device for unpacking the fibers for fabric weaving of the invention can open and grip the fiber blocks at the same time, besides the function of grabbing cotton of the traditional plucker, because the sub-bin is slidably matched with the screen 12 which can move up and down, that is, the screen 12 can slide (shake) up and down with respect to the turret 5, the partition 15 and the peripheral plate 13, by the up-and-down shaking of the screen 12, it is achieved that the fiber mass accumulated on the screen 12 is shaken along with the up-and-down shaking of the screen 12, the shaking of the fiber mass causes the movement of impurities therein, further realizing that the impurities with small adhesive force between one part of the surface of the fiber and the fiber are separated from the fiber and fall down from the meshes of the screen 12, realizing the impurity removal of the fiber, and the pre-loosening of the fiber block is realized by utilizing the shaking motion of the fiber block, so that the working loads of cotton grabbing and loosening and subsequent cylinder and roller loosening are reduced. Secondly, the invention separates a plurality of sub-bins through the partition plates 15, so that the shaking of the fibers accumulated in the annular cotton storage bin is differentiated, namely different screens 12 drive the fiber blocks in different areas to shake, on one hand, the independent shaking of the fiber blocks in different areas can be realized, the shaking of the fiber blocks on each screen 12 in a lying mode can be met, and on the other hand, the technical problems of poor control stability and poor impurity removal and dispersion efficiency caused by the integral synchronous shaking of all the fiber blocks are avoided. Thirdly, since the rotating shaft 51 of the turret 5 of the present invention rotates to drive the cotton picker 2 to rotate and to drive the height adjuster of the height adjuster 6 to move linearly in the vertical direction to adjust the height of the screen 12, the present invention couples the turret 5 and the height adjuster 6, the synchronous movement of the height adjustment members in the height adjustment device 6 is performed by the rotation of the rotating shaft 51 of the turret 5, for example, in the view of fig. 1, the rotating shaft 51 of the turret 5 is rotated counterclockwise (forward direction), the height adjusting member is ascended, the rotating shaft 51 of the turret 5 is rotated clockwise (reverse direction), the height adjusting member is descended, when the rotating shaft 51 of the turret 5 rotates anticlockwise, the cotton grabbing mechanism 2 is driven to rotate anticlockwise to open and grab the cotton fiber blocks on the upper layer, the height adjusting piece rises to drive the screen 12 to move upwards, and then satisfy and be in the fibre piece of current annular storage cotton storehouse middle and upper strata and can be opened the technological effect of snatching by plucking cotton mechanism 2 all the time. According to the invention, the linkage cooperation mode of the turret 5 and the height adjusting device 6 is adopted, so that the mode that the height of the cotton grabbing mechanism 2 is reduced by adopting the lifting movement mode of the cotton grabbing mechanism 2 in the prior art to meet the requirement of contacting with the upper-layer fiber block is abandoned, a proximity switch is not required to be configured, and the technical defect of untimely cooperation caused by signal deviation is avoided; when the rotation speed of the cotton grabbing mechanism 2 is required to be adjusted according to the compaction degree of the fiber block, the lifting speed of the height adjusting piece can be linked only by adjusting the rotation speed of the rotating shaft 51, the working parameters of a power source for realizing the rotation of the cotton grabbing mechanism 2 and a power source for realizing the lifting motion of the cotton grabbing mechanism 2 do not need to be adjusted simultaneously in the prior art, and the operation convenience is improved. Compared with the prior art that the deformation amount of the compression spring is changed by only supporting the spring below the chassis 11 through the spring and utilizing the change of the fiber gravity, the technical scheme that the fiber to be managed can be automatically lifted does not exist, the invention has the technical defects that the spring is continuously pressed, the elastic coefficient change of the spring is influenced by the repeated deformation, the resilience accuracy is low, and the technical problems of the lifting motion of the chassis 11 and the poor stability in a non-motion state caused by the deformable support of the spring do not exist.
