Due to its special physical structure, 3D upright cotton has many advantages that sponges and other ordinary fiber materials cannot match, such as recyclable, not easy to decompose, not easy to yellow, no toxic substances, strong flame retardant performance, high resilience, high pressure resistance, light texture, never discoloration, recyclable, high air permeability, high sewage discharge, easy to clean, easy to dry, not easy to deform, not easy to breed harmful bacteria, strong operability, strong expansibility, etc. It has broad application prospects and can be widely used in bra cups, clothing, shoe materials and other padding, mattresses, sofas, seats and other padding fillings, aircraft, high-speed rail, automobile and other interior decoration, medical and sanitary products, sound-absorbing and sound-insulating materials, filter materials, wall insulation materials, billboard substrates and other fields.

[0003] The production process of 3D upright cotton involves the steps of first sending the cotton laid in a mesh shape into an oven for heat setting, then extruding it into a specified thickness, and finally cooling it. However, the 3D upright cotton is usually cooled by a fan blowing directly on it, which results in low cooling efficiency. Summary of the invention

[0004] The purpose of the invention is to provide a 3D upright cotton production process, which has the effect of improving cooling efficiency.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: A 3D upright cotton production process, comprising the following steps: (S1) opening: opening the cotton fibers with a high-speed beater to make the curled cotton fibers stretch out; (S2) feeding cotton: collecting the preliminarily opened cotton fibers in a cotton bin and laying them into fiber cotton layers of equal thickness and width; (S3) combing: combing and dispersing the fiber cotton layer to obtain a cotton fiber web; (S4) laying the web: folding the combed cotton fiber web in a serpentine shape along the vertical direction to obtain a folded cotton web, and outputting it in the horizontal direction; (S5) heat setting: sending the folded cotton web into an oven for heat setting Shape; (S6) Extrusion: Extruding the folded cotton net after heat setting to the required thickness to obtain 3D upright cotton; (S7) Cooling: Air-cooling the 3D upright cotton; (S8) Slicing: Slicing the 3D upright cotton to obtain a finished product; In step S7, a cooling operation is performed by a cooling device, and the cooling device includes a frame, a plurality of cooling wind rollers rotatably arranged on the frame and blowing cold wind upward to the 3D upright cotton, an air compressor that delivers cold air to the plurality of cooling wind rollers, an air collecting hood arranged in the middle of the frame and above the plurality of cooling wind rollers, and an extraction mechanism arranged on the top of the air collecting hood and realizing the extraction of hot air in the air collecting hood.

[0006] By adopting the above technical scheme, cold air is blown upward to the 3D upright cotton through multiple cooling air rollers to achieve cooling of the 3D upright cotton. The 3D upright cotton has a sponge-like three-dimensional honeycomb fiber mesh structure, which allows cold air to pass through and achieves an efficient cooling effect. The cold air blows upward to provide an upward force on the 3D upright cotton, which can reduce the friction resistance between the 3D upright cotton and the cooling air rollers. At the same time, the temperature of the cold air rises after passing through the 3D upright cotton and becomes hot air, and the hot air is extracted through the wind collecting hood and the extraction mechanism.

[0007] The present invention is further configured as follows: the cooling air roller includes an intermediate air duct rotatably connected to the frame and with one end passing through the side of the frame, an outer shell body fixedly arranged on the circumferential side of the intermediate air duct and having strip-shaped air outlet slots on the top, and a rotating sleeve rotatably connected to the circumferential side of the outer shell body and having air outlet holes arranged in a circular array, and the air compressor delivers cold air to multiple intermediate air ducts.

[0008] By adopting the above technical solution, the compressed air output by the air compressor enters the outer shell from the middle air duct, and passes through the strip air outlet slots on the top of the outer shell and the air outlet holes of the rotating sleeve, so as to blow the cold air upward to the 3D upright cotton for cooling; at the same time, the setting of the rotating sleeve causes rolling friction between the cooling air roller and the 3D upright cotton, thereby reducing the output resistance to the 3D upright cotton.

[0009] The present invention is further configured as follows: both ends of the intermediate air duct are provided with lifting seats connected to the frame by lifting, and a first elastic component is provided between the frame and the lifting seat to drive the lifting seat to move upward; a connecting portion is provided between the top of the intermediate air duct and the strip-shaped air outlet slot hole of the outer shell, a cold water joint with a solenoid valve is provided at the bottom of one end of the outer shell, and a warm water joint with a solenoid valve is provided at the bottom of the other end of the outer shell, and a water cooling circulation mechanism is provided between the multiple cold water joints and the warm water joints; the water cooling circulation mechanism includes a cooling water tower, a first water pump connected to the cooling water tower and multiple cold water joints through a hose, and a second water pump connected to multiple warm water joints and the cooling water pump through a hose, and when the outer shell is filled with cold water, the cooling air roller overcomes the action of the first elastic component and moves downward to separate from the 3D upright cotton; The operation steps of the water cooling circulation mechanism are as follows: (S1) firstly, a plurality of cooling air rollers are divided into two cooling groups, each cooling group includes a plurality of cooling air rollers arranged at intervals; (S2) then, cold water is input to the plurality of cooling air rollers of one of the cooling groups, so that the input amount of the cold water joint is greater than the output amount of the warm water joint, and as the amount of water in the cooling air roller gradually increases, the elastic force of the first elastic component is overcome and the cooling air roller is separated from the 3D upright cotton; after the cooling of the cooling group is completed, the input of cold water is stopped, and the cold water in the cooling air roller is drained, so that the cooling air roller is reset upward when the first elastic component is reset; (S3) the operation of step (S2) is performed on the other cooling group; (S4) the operations of steps (S2) and (S3) are performed reciprocatingly.

[0010] By adopting the above technical solution, in the process of cooling the 3D upright cotton by the cooling air roller, the 3D upright cotton is in contact with the rotating sleeve, and the heat on the 3D upright cotton will gradually be transferred to the rotating sleeve, the outer shell, and the middle air duct, thereby increasing the temperature of the cold air output by the middle air duct and affecting the cooling effect. At this time, by setting up a water cooling circulation mechanism, the cooling air roller can be cooled by water. The operation steps of the water cooling circulation mechanism are as follows: (S1) firstly, a plurality of cooling air rollers are divided into two cooling groups, each cooling group includes a plurality of cooling air rollers arranged at intervals; (S2) then cold water is input to the plurality of cooling air rollers of one cooling group, so that the input amount of the cold water joint is greater than the output amount of the warm water joint, and as the amount of water in the cooling air roller gradually increases, the elastic force of the first elastic component is overcome and the cooling air roller is separated from the 3D upright cotton. After the cooling of the cooling group is completed, the input of cold water is stopped, and the cold water in the cooling air roller is drained, so that the cooling air roller is reset upward when the first elastic component is reset; (S3) the operation of step (S2) is performed on the other cooling group; (S4) the operations of steps (S2) and (S3) are performed reciprocatingly. During the operation of the above step (S2), the multiple cooling wind rollers of the cooling group still blow the cold wind upward to ensure the cooling amount of the 3D upright cotton. Because the cooling wind rollers are separated from the 3D upright cotton, the temperature can be quickly reduced under the action of the water cooling circulation mechanism. At the same time, after the cold water in the cooled cooling wind rollers is emptied, the cooling wind rollers are reset upward. At this time, the cooling air duct can also exchange heat with the 3D upright cotton during the contact process, further accelerating the cooling of the 3D upright cotton. During the operation of the above step (S4), the two cooling groups are alternately cooled, which can ultimately improve the cooling effect of the 3D upright cotton.

In addition, on the basis of setting the mesh plate to achieve negative pressure suction, some cotton fibers will be attached to the bottom of the mesh plate during long-term use, thereby affecting the air flow at the mesh plate; at this time, by setting the auxiliary air duct, the auxiliary air duct, the first baffle, the slag removal mechanism and the linkage mechanism, the first baffle is opened through the linkage mechanism during the movement of the slag removal mechanism toward the auxiliary air duct, and the scraped cotton fibers are transported to the bottom of the auxiliary air duct.

[0016] By adopting the above technical solution, when scraping the slag, the extraction mechanism is first closed, and then the two first sliding seats and the support rod are driven to move by the push handle, which can drive the scraper that abuts against the lower surface of the mesh plate to move, thereby scraping off the cotton fibers attached to the lower surface of the mesh plate, and the cotton fibers that fall after scraping can be collected in the slag trough, and finally when the scraper moves into place, the cotton fibers in the slag trough are extracted by the extraction mechanism.

[0039] Implementation effect: cold air is blown upward toward the 3D upright cotton through multiple cooling air rollers 2 to achieve cooling of the 3D upright cotton. The 3D upright cotton has a sponge-like three-dimensional honeycomb fiber mesh structure, which allows cold air to pass through and achieves an efficient cooling effect. The cold air blows upward to provide an upward force on the 3D upright cotton, which can reduce the friction resistance between the 3D upright cotton and the cooling air rollers 2. At the same time, the temperature of the cold air rises after passing through the 3D upright cotton and becomes hot air, and the hot air is extracted through the wind collecting hood 4 and the extraction mechanism 5.

[0040] The compressed air output by the air compressor 3 enters the outer shell 22 from the middle air duct 21, and passes through the strip air outlet slot 221 on the top of the outer shell 22 and the air outlet hole 231 of the rotating sleeve 23, so as to blow the cold air upward to the 3D upright cotton for cooling; at the same time, the setting of the rotating sleeve 23 makes the cooling air roller 2 and the 3D upright cotton have rolling friction, thereby reducing the output resistance to the 3D upright cotton.

[0041] When the cooling roller 2 cools the 3D upright cotton, the 3D upright cotton contacts the rotating sleeve 23, and the heat on the 3D upright cotton is gradually transferred to the rotating sleeve, the outer shell 22, and the intermediate air duct 21, thereby increasing the temperature of the cold air output by the intermediate air duct 21, affecting the cooling effect. At this time, the cooling roller 2 can be water-cooled by setting a water-cooling circulation mechanism.

[0042] When the hot air under the wind hood 4 is extracted by the extraction mechanism 5, some cotton fibers will be carried in the air flow process, and the filter 53 can filter the cotton fibers at this time; and a mesh plate 42 is provided at the bottom of the wind hood 4, which can increase the negative pressure in the wind hood 4, so that the hot air under the mesh plate 42 can flow into the wind hood 4 more evenly. In addition, on the basis of setting the mesh plate 42 to achieve negative pressure suction, some cotton fibers will be attached to the bottom of the mesh plate 42 during long-term use, thereby affecting the air flow at the mesh plate 42; at this time, by setting the auxiliary air duct 41, the auxiliary air duct 43, the first baffle plate 44, the slag removal mechanism 7 and the linkage mechanism, the first baffle plate 44 is opened through the linkage mechanism during the movement of the slag removal mechanism 7 toward the auxiliary air duct 41, and the scraped cotton fibers are transported to the bottom of the auxiliary air duct 41.

[0043] When scraping the residue, first close the extraction mechanism 5, and then drive the two first sliding seats 72 and the support rod 73 to move by the push handle 75, so as to drive the scraper 74 abutting against the lower surface of the mesh plate 42 to move, thereby scraping off the cotton fibers attached to the lower surface of the mesh plate 42, and the cotton fibers that fall after scraping can be collected in the residue groove 741, and finally when the scraper 74 moves into place, the cotton fibers in the residue groove 741 are extracted by the extraction mechanism 5.

[0044] First, by setting the tension spring 81, the first shielding plate 44 can be kept in a closed state when no external force is applied; at the same time, when the first sliding seat 72 moves toward the direction close to the first shielding plate 44, the second wedge block 83 contacts the first wedge block 82 to open the first shielding plate 44, and then the slag groove 741 of the scraper 74 moves to the bottom of the auxiliary air duct 41, and finally the cotton fibers in the slag groove 741 are extracted by the extraction mechanism 5. When the cotton fibers in the slag groove 741 are extracted by the extraction mechanism 5, the second shielding plate 46, the second elastic component 47 and the cable mechanism are set, so that when the first sliding seat 72 moves to the direction close to the auxiliary air duct 41, the cable mechanism drives the second shielding plate 46 to cover the connection between the air outlet pipe 51 and the air collecting cover 4, thereby increasing the negative pressure at the auxiliary air duct 41. When the first sliding seat 72 moves in a direction away from the auxiliary air duct 41 under the action of the cable mechanism, the second compression spring 473 is gradually compressed, so that after the cable mechanism is relaxed, the second compression spring 473 can drive the first sliding seat 72 to reset under the reset action. Because the displacement distance of the support rod 73 of the scraper mechanism and the displacement distance of the second shielding plate 46 are different, the elastic rope is set. 95 elastic deformation, thereby overcoming the displacement difference between the two, and finally realizing that when the first sliding seat 72 moves to the direction close to the auxiliary air duct 41, the cable mechanism drives the second shielding plate 46 to cover the connection between the air outlet pipe 51 and the air collecting cover 4.
