[0001] The present application relates to the field of spinning technology, in particular to a cotton carding device of a suction type rotor spinning machine. BACKGROUND

[0002] Rotor spinning belongs to free end spinning and is one of the more mature representatives of new spinning technologies. In recent years, with the upgrading of rotor spinning machines, their various performances have been continuously improved and increased, the whole machine has developed towards high speed, high yield, expansion of the spinning range, energy saving and consumption reduction, and the cotton carding device used in the rotor spinning machine has also developed rapidly and progressed;

[0003] The existing cotton carding device of a suction type rotor spinning machine with publication number CN220643358U knocks and loosens the cotton through a double-sided knocking and loosening feeding assembly, then transports the cotton, can effectively avoid the caked cotton from being lifted, has good carding effect, and the double-sided knocking and loosening feeding assembly can move in the cotton pile to knock and feed, does not need to install a conveying structure on the bottom layer of cotton, saves production cost, has novel structure, low cost and strong practicality;

[0004] However, according to the description and the drawings shown in the description, the knocking plate only loosens the cotton in a top-down manner, and the longitudinal displacement amplitude of the cotton is limited, so the loosening effect is poor;

[0005] Therefore, the present application provides a cotton carding device of a suction type rotor spinning machine to meet the needs. CONTENT OF THE INVENTION

[0006] Therefore, the present application provides a cotton carding device of a suction type rotor spinning machine to meet the needs.

[0007] To solve the above technical problems, the present application provides the following technical solutions:

[0008] A cotton carding device of a suction type rotor spinning machine, comprising a box body, a feeding port is arranged on the side surface of the box body, a carding assembly is arranged on the inner side wall of the box body, and a driving assembly is arranged on the outer side wall of the box body.

[0009] The carding assembly comprises an upper carding plate, a lower carding plate and a carding roller, the upper carding plate and the lower carding plate are arranged in parallel, and the carding roller is arranged on one side of the lower carding plate.

[0010] The driving assembly comprises a motor, a belt pulley, a sliding sleeve and a sliding block, the motor is fixedly installed on the side wall of the box body, the belt pulley is fixedly installed on the output end of the motor, the sliding sleeve is fixed to the end of the upper carding plate, and the sliding block is eccentrically installed on the side wall of the belt pulley.

[0017] Compared with the prior art, this application has at least the following advantages:

[0018] In the above scheme, by setting up an upper carding plate and a lower carding plate, the upper carding plate moves back and forth in the vertical direction, pressing the connecting plate upward and driving the lower carding plate to move upward, so that the cotton block has an upward displacement effect.

[0027] Box 1, upper combing plate 2, protrusion 201, lower combing plate 3, connecting plate 301, combing teeth 302, combing roller 4, combing needle 401, motor 5, pulley 501, sliding sleeve 502, slider 503. Detailed Implementation

[0028] like Figure 1 , Figure 2 , Figure 3 The carding device of the exhaust rotor spinning machine shown in the embodiment of this application includes a box 1, a feed inlet is provided on the side of the box 1, a carding assembly is provided on the inner side wall of the box 1, and a drive assembly is provided on the outer side wall of the box 1.

[0029] The carding assembly includes: an upper carding plate 2, a lower carding plate 3, and a carding roller 4. The upper carding plate 2 and the lower carding plate 3 are arranged parallel to each other, and the carding roller 4 is located on one side of the lower carding plate 3.

[0030] The drive assembly includes: a motor 5, a pulley 501, a sliding sleeve 502, and a slider 503. The motor 5 is fixedly installed on the side wall of the housing 1, the pulley 501 is fixedly installed on the output end of the motor 5, the sliding sleeve 502 is fixed to the end of the upper combing plate 3, and the slider 503 is eccentrically installed on the side wall of the pulley 501.

[0031] Cotton is fed into the box 1 through the feed inlet. The feed inlet is located between the upper carding plate 2 and the lower carding plate 3. Driven by the motor 5, the pulley 501 rotates, causing the slider 503 to squeeze the sliding sleeve 502, which in turn causes the sliding sleeve 502 to move back and forth in the vertical direction, driving the upper carding plate 2 to move downward. The bottom surface of the upper carding plate 2 and the top surface of the lower carding plate 3 are provided with protrusions to pierce the cotton, making the cotton clumps expand and loosen.

[0032] In this embodiment, as Figures 2-5 As shown, the lower combing plate 3 has an "L"-shaped connecting plate 301 on its edge, and the right-angled inner corner of the connecting plate 301 is engaged in the side wall groove of the upper combing plate 2.

[0033] During the reciprocating motion of the upper carding plate 2 in the vertical direction, the upper carding plate 2 moves upward and squeezes the connecting plate 301, which drives the lower carding plate 3 to move upward, so that the cotton block has the effect of upward displacement. When the upper carding plate 2 moves downward and separates from the connecting plate 301, the lower carding plate 3 falls to achieve the effect of thrashing the cotton block, thereby improving the loosening effect of the cotton block.

[0034] The side wall of the box 1 is provided with a strip-shaped hole, and the edge of the upper comb plate 2 is provided with a protrusion 201. The protrusion 201 is provided through the strip-shaped hole in the side wall of the box 1, and the sliding sleeve 502 is fixedly connected to the outside of the protrusion 201.

[0035] The upper carding plate 2 is limited by the strip-shaped holes on the side wall of the box 1, so that the upper carding plate 2 can only move in the vertical direction. The upper carding plate 2 beats the cotton block from top to bottom, and the lower carding plate 3 beats the cotton block from bottom to top, thereby improving the loosening effect.

[0036] A transmission relationship is established between pulley 501 and carding roller 4;

[0037] The pulley 501 and the carding roller 4 are connected by belt drive. The pulley 501 drives the upper carding plate 2 and the lower carding plate 3 to move. At the same time, the carding roller 4 rotates to card the cotton from the edge of the lower carding plate 3. The surface of the carding roller 4 can be set with carding texture to achieve a better carding effect. At the same time, as the carding roller 4 rotates, centrifugal force is applied to the carded cotton lint, so that the cotton lint can be thrown out and further loosened.

[0038] Meanwhile, because the lower carding plate 3 has a state of moving back and forth in the vertical direction, the distance between the edge of the lower carding plate 3 and the carding roller 4 is not fixed. During the up and down movement of the cotton lint at the edge of the lower carding plate 3, it comes into contact with the carding roller 4, and the cotton lint is subjected to shear force and is carded, which has a good carding effect.

[0039] The upper surface of the lower carding plate 3 is flush with the lower surface of the carding roller 4;

[0040] Space is reserved to prevent cotton wadding from being flattened by the lower carding plate 3 and carding roller 4.

[0041] The side wall of the lower carding plate 3 is connected with carding teeth 302, and a groove is provided between two adjacent carding teeth 302. The outer side wall of the carding roller 4 is provided with carding needles 401.

[0042] The combing teeth 302 and the combing pins 401 can mesh with each other to achieve a combing effect.

[0043] The outer peripheral surface of the carding roller 4 is tangent to the end of the carding tooth 302;

[0044] The combing teeth 302 can move vertically relative to the combing roller 4, so that the combing teeth 302 comb the cotton in the up and down direction relative to the combing needles 401;

[0045] The combing needle 401 is in a reciprocating rotation state, which can transfer the cotton on the combing teeth 302 in a fluffy state to the outlet position of the box 1, so as to facilitate the connection with downstream equipment.
