Description

Technical Field

[0001] The invention belongs to the field of unwinding mechanisms, in particular to a fluffy cotton unwinding mechanism. Background Art

[0002] As the requirements for water absorption performance of products such as diapers continue to increase, fluffy cotton has been widely used as a water-absorbing material for diapers. Fluffy cotton has good fluffiness and softness, and can provide sufficient expansion space for absorbent resin, thereby achieving excellent water absorption effect.

[0003] In the composite processing of fluffy cotton, in order to stably deliver the fluffy cotton to be composited to the composite processing area, a fluffy cotton unwinding mechanism is usually used to unwind the rolled fluffy cotton at a uniform speed to supply it to the subsequent composite processing steps. However, in the prior art, when the fluffy cotton unwinding mechanism is used to deliver the fluffy cotton to the composite processing area, it is often necessary to spray hot melt adhesive on the unrolled fluffy cotton. This operation will form a layer of hard adhesive film on the surface and inside of the fluffy cotton, which will block the hollow structure of the fluffy cotton, restricting the hollow part that should be able to fully unfold and expand, resulting in the inability of the hollow structure of the fluffy cotton to fully display, hindering the expansion of the water-absorbing resin, and thus seriously affecting the water absorption effect of the product.

[0004] In addition, when in use, the traditional fluffy cotton unwinding mechanism can only stably deliver the fluffy cotton into the composite area for composite processing, but it cannot reduce the above-mentioned adverse effects of hot melt adhesive on the fluffy cotton. Therefore, improving the fluffy cotton unwinding mechanism so that it can effectively reduce the adverse effects of hot melt adhesive on the performance of fluffy cotton while ensuring stable transportation of the fluffy cotton has become a technical problem that needs to be solved urgently.

[0005] To this end, the present invention provides a fluffy cotton unwinding mechanism. Summary of the invention

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 8 As shown, a fluffy cotton unwinding mechanism of an embodiment of the present invention includes a machine table 1, an unwinding roller 2 arranged at the top rear end of the machine table 1, a winding roller 6 arranged at the top front end of the machine table 1, and a tensioning roller 3 arranged at the front end of the unwinding roller 2, a top frame 5 is arranged at the rear end of the winding roller 6, a needle cloth roller 4 is arranged at the rear end of the top frame 5, an upper pressure plate 51 is fixed to the top end inside the top frame 5, upper side plates 52 are arranged on both sides of the upper pressure plate 51, a lower pressure plate 7 is arranged below the upper pressure plate 51, lower side plates 71 are arranged on both sides of the top of the lower pressure plate 7, an inclined block 81 is fixed to the inner side of the lower side plate 71, and a side push block 72 is arranged at the middle position of the lower side plate 71.

[0032] The surface of the side push block 72 facing the middle position of the top of the lower pressure plate 7 is an inclined surface, and the inclined surfaces of the two side push blocks 72 correspond to each other. The part of the lower side plate 71 facing the tensioning roller 3 is narrower, and the part of the lower side plate 71 facing the winding roller 6 is wider. The distance between the two lower side plates 71 gradually narrows from the tensioning roller 3 to the winding roller 6. The top surface of the inclined block 81 is an inclined surface and is located at the inner corner of the lower side plate 71.

[0033] The fluffy cotton to be compounded is loaded on the unwinding roller 2, and the fluffy cotton loaded on the unwinding roller 2 is led out and passed through the five tensioning rollers 3, and the tensioning rollers 3 are used to reduce the tension of the fluffy cotton to the same speed as the main equipment. It should be noted that the five tensioning rollers 3 can adjust the speed, which can be faster than the original speed of the equipment, so that the fluffy cotton becomes wider and reduces the loss, and can also reduce the stretching of the fluffy cotton and make the core more fluffy;

[0034] The fluffy cotton that has been tensioned by five tensioning rollers 3 is sent to the bottom of the needle cloth roller 4, and the needle cloth roller 4 is used to break up the fiber bundles and rearrange them, so that the originally tightly interwoven fibers become looser. At the same time, the penetration and stirring of the needles will create more space between the fibers, thereby increasing the hollow gaps of the fluffy cotton. More hollow gaps mean that there is more space to accommodate the polymer water-absorbing resin, and it helps the water-absorbing resin to fully expand when absorbing water, thereby improving the water absorption performance;

[0035] A slitting assembly is installed at the position of the feeding port of the upper pressing plate 51 and the lower pressing plate 7, and the slitting assembly is used to slit the two sides of the fluffy cotton entering between the upper pressing plate 51 and the lower pressing plate 7. A gap for folding the side edges of the fluffy cotton is formed between the upper side plate 52 and the lower side plate 71, and the gap gradually narrows after starting from the inclined surface of the side push block 72. When the fluffy cotton is fed between the upper pressing plate 51 and the lower pressing plate 7, the middle part of the fluffy cotton moves straightly under the pressure of the upper pressing plate 51 and the lower pressing plate 7, and the two sides of the fluffy cotton are lifted up by the inclined surface of the inclined block 81 and moved into the gap formed by the upper side plate 52 and the side plate 71, and the upturned two sides of the fluffy cotton gradually move toward the side push block 72. The inclined surface position is squeezed and folded by the inclined surface of the side push block 72 and the side wall of the upper side plate 52, and the two sides of the fluffy cotton continue to move in the gap between the upper pressing plate 51 and the lower pressing plate 7. As the gap between the upper pressing plate 51 and the lower pressing plate 7 is reduced and contacts with the two sides of the folded fluffy cotton, the two sides of the fluffy cotton are folded by the upper pressing plate 51 and the lower pressing plate 7. At this time, the two sides of the fluffy cotton core can be cut and folded into a concave structure to form a middle guide groove, thereby accelerating the flow speed of the liquid in the core, so that the water can be dispersed and absorbed faster, and the liquid quickly penetrates into the entire core along the guide groove, increasing the contact area and speed of water absorption;

[0036] It should be noted here that the narrowed gap between the upper pressing plate 51 and the lower pressing plate 7 can be adjusted to a spacing that matches the thickness of the fluffy cotton according to actual usage requirements, so as to ensure that the narrower gap between the upper pressing plate 51 and the lower pressing plate 7 can be used to fold the side edges of the fluffy cotton so that its two sides are folded into a concave structure.

[0037] like Figures 1 to 8 As shown, an air jet groove 83 is opened inside the inclined block 81, and the nozzle of the air jet groove 83 faces upward. An air guide groove 84 is set at the bottom of the air jet groove 83. The air guide groove 84 is opened inside the lower side plate 71, and the air inlet of the air guide groove 84 is located on the outer wall of the lower side plate 71. An air injection pipe 82 is installed on the outer wall of the lower side plate 71. The air injection pipe 82 is connected with the air inlet of the air guide groove 84. An air inlet pipe 8 is installed on the top of the air injection pipe 82, and the top of the air inlet pipe 8 protrudes from the top of the top frame 5.

[0038] Connect the blower to the air inlet pipe 8, and use the blower to blow air into the air inlet pipe 8. The air enters the air guide groove 84 through the air injection pipe 82, and is blown upward through the air injection groove 83 opened in the inclined block 81.

[0039] When the fluffy cotton is fed between the upper pressing plate 51 and the lower pressing plate 7, the middle part of the fluffy cotton moves straightly due to the pressure of the upper pressing plate 51 and the lower pressing plate 7, and the two sides of the fluffy cotton are lifted up by the inclined surface of the inclined block 81 and move into the gap formed by the upper side plate 52 and the lower side plate 71. At the same time, the two side edges of the fluffy cotton are lifted up by the upward blowing effect of the wind. The inclined surface of the inclined block 81 and the upward blowing force of the wind enable the two side edges of the fluffy cotton to lift up quickly.

[0040] like Figures 1 to 8 As shown, a side groove 9 is opened on the inclined surface of the side thrust block 72, a pulley 91 is rotatably arranged inside the side groove 9, a push belt 93 is arranged outside the pulley 91, a driving motor 92 is installed at the top end inside the side groove 9, and the rotating shaft at the bottom of the driving motor 92 is connected to the top of one of the pulleys 91.

[0041] The upturned fluffy cotton on both sides gradually moves to the inclined position of the side push block 72, and the driving motor 92 is started. The driving motor 92 drives the pulley 91 to rotate so that the pushing belt 93 is continuously transported, and the upturned fluffy cotton on both sides is squeezed and folded by the inclined surface of the side push block 72 and the side wall of the upper side plate 52, and at the same time is pushed by the pushing belt 93 and fits with the side wall of the upper side plate 52, so that the upturned fluffy cotton on both sides can be folded and vertically enter the narrow gap between the upper pressing plate 51 and the lower pressing plate 7.

[0042] like Figures 1 to 8 As shown, a bottom groove 73 is provided at the bottom end of the lower pressure plate 7, and a gear 74 is rotatably arranged inside the bottom groove 73. Push tooth plates 75 are meshed at both ends of the gear 74. One side of a push tooth plate 75 is fixedly connected to a lower side plate 71, and one side of the other push tooth plate 75 is fixedly connected to the other lower side plate 71. A servo motor 76 is provided below the gear 74, and the servo motor 76 is installed at the bottom of the lower pressure plate 7. The rotating shaft at the top of the servo motor 76 extends to the inside of the bottom groove 73 and is fixedly connected to the bottom of the gear 74. The two upper side plates 52 are laterally slidably arranged on both sides of the upper pressure plate 51, and the upper side plate 52 is placed on the inner side of the lower side plate 71 and fixedly connected thereto.

[0043] Since the lower side plate 71 is fixedly connected to the upper side plate 52, the push tooth plate 75 can push the lower side plate 71 to move and drive it and the upper side plate 52 to move, and the positions of the lower side plate 71 and the upper side plate 52 are adjusted according to the actual width of the fluffy cotton to ensure that it can be suitable for the folding work of the two sides of the fluffy cotton with different widths;

[0044] Start the servo motor 76, which drives the gear 74 to rotate. The gear 74 pushes the push tooth plates 75 at both ends to move outside the bottom groove 73, and the lower side plates 71 follow the push tooth plates 75 to move. The lower side plates 71 located on both sides of the lower pressure plate 7 expand and the spacing increases to accommodate wider fluffy cotton. Conversely, the gear 74 reverses, and the push tooth plates 75 move toward the inside of the bottom groove 73, driving the lower side plates 71 to move toward the position of the lower pressure plate 7, and the spacing between the lower side plates 71 is reduced to accommodate narrower fluffy cotton.

[0045] like Figures 1 to 8 As shown, a pushing block 41 is provided on one side of the top of the needle clothing roller 4, and the pushing block 41 is fixed to the end of the top frame 5. The inner side wall of the pushing block 41 is in contact with the outer wall of the needle clothing roller 4. A built-in cavity 42 is provided inside the needle clothing roller 4, and a push plate 43 is provided inside the built-in cavity 42. A plurality of needles 44 are fixed to the end of the push plate 43. Reset grooves 45 are provided at the top and bottom ends of the built-in cavity 42, and a slide bar 47 is fixed inside the reset groove 45. A reset block 46 is sleeved on the outside of the slide bar 47. The reset block 46 is fixed to the top and bottom of the push plate 43 and can slide on the outside of the slide bar 47. A reset spring 48 is wound around the outside of the slide bar 47, and one end of the reset spring 48 is fixedly connected to the inner wall of the reset groove 45, and the other end of the reset spring 48 is fixedly connected to the end of the reset block 46.

[0046] The card clothing roller 4 is connected to the driving mechanism to rotate, and the rotation direction of the card clothing roller 4 is as follows: Figure 7 As shown by the middle arrow, in the default state, the needle 44 is retracted into the built-in cavity 42. When the needle cloth roller 4 rotates, the extended end of the push plate 43 is retracted into the built-in cavity 42 by the pressure of the inner wall of the push block 41, and the other end of the push plate 43 pushes the needle 44 to push it out of the built-in cavity 42. When the push plate 43 is continuously subjected to the pressure of the inner wall of the push block 41, the needle 44 extends to break up the fluffy cotton passing through the bottom of the needle cloth roller 4, rearranges it, and makes the originally tightly interwoven fibers become looser. At the same time, the insertion and stirring of the needles will create more space between the fibers, thereby increasing the hollow gaps in the fluffy cotton.

[0047] When one end of the push plate 43 is retracted into the built-in cavity 42 by the pressure of the push block 41, the push plate 43 drives the reset block 46 to move outside the slide rod 47, and the reset block 46 pushes the reset spring 48 to shrink it. When one end of the push plate 43 is not retracted into the built-in cavity 42 by the pressure of the inner wall of the push block 41, the reset spring 48 uses the elastic force to push the reset block 46 to move and drive one end of the push plate 43 to move out of the built-in cavity 42, and the needle 44 fixed at the other end of the push plate 43 is retracted into the built-in cavity 42. The needle cloth roller 4 rotates continuously, and the needle 44 moves out of the built-in cavity 42 to stir, comb and stretch the fibers of the fluffy cotton passing through the bottom of the needle cloth roller 4, thereby expanding the original fiber gap and forming more hollow gaps.

[0048] When treatment is required, the needles 44 can be accurately extended to treat the fluffy cotton in a specific area, thereby improving the treatment accuracy and effect; when treatment is not required, the needles 44 are retracted to prevent excessive stirring, combing and stretching of the fluffy cotton, thereby ensuring the stability of the structure and performance of the fluffy cotton and the consistency of product quality; when the needle cloth roller 4 is not in contact with the fluffy cotton, the needles 44 are retracted in the built-in cavity 42 to prevent the needles 44 from accidentally colliding with other objects and being damaged, thereby extending the service life of the needle cloth roller 4;

[0049] The needle cloth roller 4 is used to break up the fiber bundles and rearrange them, so that the originally tightly interwoven fibers become looser. At the same time, the penetration and stirring of the needles will create more space between the fibers, thereby increasing the hollow gaps of the fluffy cotton. More hollow gaps mean that there is more space to accommodate the polymer water-absorbing resin, and it helps the water-absorbing resin to fully expand when absorbing water, thereby improving the water absorption performance.
