Description

Technical Field

[0001] The invention belongs to the technical field of non-woven fabric production, and particularly relates to a non-woven fabric fiber web hot air drying and rolling device. Background Art

[0002] Spunlace nonwoven fabric is made by spraying high-pressure fine water flow onto one or more layers of fiber webs, causing the fibers to entangle with each other, thereby reinforcing the fiber web and giving it a certain strength. The resulting fabric is a spunlace nonwoven fabric.

[0003] The production process of spunlace nonwovens mainly includes the following core steps:

[0004] 1. Fiber selection: The raw materials can be natural fibers (such as cotton, wood pulp) or synthetic fibers (such as polyester, nylon). Commonly used raw materials include viscose fibers, polyester fibers, etc.

[0005] 2. Fiber opening and combing: The fibers are loosened by an opener, and then arranged into a mesh structure through a combing process.

[0006] ‌3. Hydroentanglement‌: High-pressure water is sprayed onto the fiber web through a nozzle. The pressure of the water causes the fibers to entangle with each other and combine tightly to form a fabric with a certain strength.

[0007] ‌4. Drying and shaping‌: The moisture is removed through drying equipment, and finally the fabric is shaped to give it a certain dimensional stability.

[0008] ‌5. Curling and cutting‌: The treated spunlace nonwoven fabric will be rolled into large rolls and cut into different sizes according to specific needs.

[0009] At present, a Chinese patent with publication number CN118979336A and publication date November 19, 2024 discloses a spunlace non-woven fabric composite processing technology, and the specific steps are as follows: Step 1: Select two fiber raw materials, and comb and shape them into a web through a carding machine and a cross-laying process respectively to obtain an outer fiber web and an inner fiber web. The outer fiber web is made of polyester fiber and viscose fiber, and the inner fiber web is made of pure cotton fiber or mulberry silk fiber; Step 2: The outer fiber web and the inner fiber web are stretched by a stretching machine; Step 3: Move the outer fiber web and the inner fiber web into the spunlace machine, and the spunlace machine flattens the two fiber webs, and then combines the two together using a spunlace process to form a composite fiber web; Step 4: After the obtained composite fiber web is impregnated, it is rolled; Step 5: The rolled fiber web is input into an oven for drying to obtain a spunlace non-woven fabric.

[0010] In this spunlace nonwoven composite processing technology, the fiber web after rolling needs to be transferred into an oven for hot air drying, and the nonwoven fiber web after drying will be rolled and wrapped, and then it can be transported and sold; after the nonwoven fiber web is hot-air dried, the temperature of the surface of the nonwoven fiber web is relatively high. If the nonwoven fiber web is directly rolled and wrapped, the plastic film wrapped around the nonwoven fiber web is easily damaged by heat, which is not conducive to the rolling and wrapping of the nonwoven fiber web.

At this time, multiple wrapping covers on the first bracket are used. The centrifugal fan on the wrapping cover can bring the outside air into the wrapping cover after working. The air ejected from under the multiple wrapping covers can pass through the non-woven fiber web, thereby taking away the heat on the surface of the non-woven fiber web. Finally, the non-woven fiber web after drying can be cooled, which is convenient for the subsequent winding and wrapping of the non-woven fiber web.

[0019] By adopting the above technical solution, when the non-woven fiber web on the winding shaft is wound, the docking sleeve is slid toward the side away from the winding shaft, and then the docking sleeve can be separated from the end of the winding shaft, and the quick disassembly between the winding shaft and the first connection end and the second connection end can be quickly completed; at the same time, when the winding shaft needs to be connected with the first connection end and the second connection end, the end face of the winding shaft is aligned with the end faces of the first connection end and the second connection end, and then the docking sleeve can be slid toward the side close to the winding shaft, so that the docking sleeve is wrapped around the end of the winding shaft, thereby completing the quick installation between the winding shaft and the first connection end and the second connection end.

[0020] The present invention is further configured as follows: the upper end of the first vertical rod is rotatably connected to a winding shaft, and the winding shaft is sleeved with a plastic film roll for wrapping the circumferential side of the non-woven fiber web roll rolled up on the winding shaft.

[0021] By adopting the above technical scheme, after the non-woven fiber web on the winding shaft is wound up, the winding shaft connected to the upper end of the first vertical rod is rotated, and a plastic film roll is sleeved on the winding shaft. The operator rolls the plastic film and bonds the end of the plastic film to the outer wall of the non-woven fiber web roll. Then, the winding shaft is driven to rotate around the winding shaft for one circle, so that the non-woven fiber web roll can be quickly wrapped by the plastic film, and finally the packaging operation of the non-woven fiber web roll can be completed on the winding shaft.

[0022] The present invention is further configured as follows: the second transmission belt includes a driving shaft rotatably connected between the second brackets on both sides, a driving sprocket arranged at both ends of the driving shaft, a driven shaft rotatably connected between the second brackets on both sides, a driven sprocket arranged at both ends of the driven shaft, a chain arranged between the driving sprocket and the driven sprocket, a plurality of transmission shafts arranged between the chains on both sides and used to abut against the lower surface of the non-woven fiber web, a driving motor arranged at the outer wall of the second bracket on one side, a driving pulley arranged on the output shaft of the driving motor, a driven pulley arranged at the end of the driving shaft, and a connecting belt arranged between the driving pulley and the driven pulley; the second bracket is provided with a linkage component which drives the winding shaft to rotate around the winding shaft once by the driving motor after the non-woven fiber web on the winding shaft is wound up.

[0023] By adopting the above technical solution, after the driving pulley is driven to rotate by the driving motor, the driving pulley can drive the driving shaft to rotate through the connecting belt and the driven pulley, and the driving shaft can drive multiple transmission shafts through the driving sprocket, the driven sprocket and the chain to drive the non-woven fiber web to move; at the same time, when the non-woven fiber web on the winding shaft is wound up, the linkage component can be used to drive the winding shaft to rotate around the winding shaft for one circle through the driving motor, thereby realizing the dual utilization of the driving motor.

[0024] The present invention is further configured as follows: the linkage assembly includes a seat sleeve fixed to the upper end of the first vertical rod, a turntable rotatably connected to the seat sleeve, a semicircular sleeve arranged on the side wall of the turntable and for the pulley to be embedded, an L-shaped angled arm with one end connected to the semicircular sleeve and the other end connected to the end of the winding shaft, an arc-shaped opening opened at the upper end of the first vertical rod and for the angled arm to rotate, a rotating shaft arranged on the side of the turntable away from the semicircular sleeve, a driven gear arranged on the rotating shaft, a sliding seat connected to the first vertical rod for sliding up and down, a first bearing seat arranged on the sliding seat, a linkage shaft rotatably connected to the first bearing seat, a driving gear arranged on the linkage shaft and used to mesh with the driven gear after moving up, a moving pulley arranged at the end of the linkage shaft, an elastic belt arranged between the moving pulley and the driving pulley, and a driving member arranged on the second bracket and used to drive the slide seat to move up.

[0025] By adopting the above technical scheme, when the non-woven fiber web on the winding shaft is wound, the upward-moving winding shaft causes the pulley to be embedded in the semicircular sleeve, so that the central axis of the winding shaft and the central axis of the winding shaft are in the same straight line; then the driving member is used to drive the slide seat to move upward, and the slide seat can drive the moving pulley and the driving gear to move upward, and the elastic belt undergoes elastic deformation until the driving gear and the driven gear on the rotating shaft are engaged. At the same time, after the elastic belt is tensioned, the driving motor can drive the linkage shaft to rotate through the driving pulley and the elastic belt. After the linkage shaft rotates, the turntable can be driven to rotate through the driving gear and the driven gear, and the turntable can drive the winding shaft to rotate through the folding arm, and then the winding shaft can drive the plastic film to rotate around the winding shaft, thereby wrapping the plastic film around the non-woven fiber web.

[0026] The present invention is further configured as follows: guide columns extending in a vertical downward direction are arranged on both sides of the lower surface of the slide seat, guide sleeves for the guide columns to pass through are arranged on both sides of the lower end of the first vertical rod, and a tensioning spring is provided on the guide column, the upper end of which is connected to the slide seat and the lower end is connected to the guide sleeve.

[0027] By adopting the above technical solution, the slide uses a guide column to pass through the guide sleeve, and the upper end of the tensioning spring is connected to the slide and the lower end is connected to the guide sleeve. The tensioning spring can ensure that the moving pulley on the slide can always maintain a connection with the elastic belt, thereby preventing the elastic belt from falling off the moving pulley after the slide moves downward for too long a distance.

[0029] By adopting the above technical solution, after the piston rod of the driving cylinder is pushed downward, the piston rod can push the flap, and after the flap swings downward, it can drive the push rod to swing upward, and then the push rod can contact the linkage shaft and drive the slide seat to move upward.

[0030] The present invention is further configured as follows: a long groove communicating with the slide groove is provided on the side wall of the second vertical rod, an extension shaft passing through the long groove is provided on the second connecting end, a counterweight block is provided at the end of the extension shaft away from the second connecting end, a push plate for abutting against the extension shaft and driving the pulley to be embedded in the semicircular sleeve is provided at the end of the mounting shaft away from the push rod, and a cutting blade for being embedded in a position between adjacent transmission shafts is also provided on the lower surface of the flap; when the push plate pushes the extension shaft upwards to drive the pulley to be embedded in the semicircular sleeve, the non-woven fiber mesh roll on the winding shaft is raised and a gap is left between the non-woven fiber mesh roll and the transmission shaft for the plastic film roll to pass through.

[0031] By adopting the above technical scheme, when the non-woven fiber web on the winding shaft is wound, a gap is left between the pulley and the semicircular sleeve. At this time, the driving cylinder can drive the push rod to swing upward and can also drive the push plate to swing upward. After the push plate swings upward, it can push the extension shaft, and then the extension shaft can drive the pulley and the winding shaft to move upward, and the pulley can be embedded in the semicircular sleeve. At this time, after the winding shaft moves up, a gap can be created between the non-woven fiber web roll and the second conveyor belt for the plastic film roll to pass through; at the same time, when the flap swings downward, the cutting blade on the lower surface of the flap can be used to embed the cutting blade between adjacent transmission shafts to cut off the non-woven fiber web, and there is no need for manpower to cut the non-woven fiber web.

[0032] The beneficial effect of the present invention is that after the non-woven fiber web is dried with hot air in the oven, the non-woven fiber web transmitted from the oven can enter the first conveyor belt, and at this time, the multiple wrapping covers on the first bracket are used. The centrifugal fan on the wrapping cover can bring the outside air into the wrapping cover after working, and the air ejected from the bottom of the multiple wrapping covers can pass through the non-woven fiber web, thereby taking away the heat on the surface of the non-woven fiber web, and finally the non-woven fiber web after drying can be cooled, which is convenient for the subsequent winding and film wrapping of the non-woven fiber web by the winding shaft;

[0033] When the non-woven fiber web on the take-up shaft is wound up, there is still a gap between the pulley and the semicircular sleeve. At this time, the driving cylinder can also drive the push plate to swing upward when driving the push rod to swing upward. After the push plate swings upward, it can push the extension shaft, and then the extension shaft can drive the pulley and the take-up shaft to move upward. At the same time, the operator holds the plastic film roll by hand to control the position of the semicircular sleeve, and then the pulley can be embedded in the semicircular sleeve, and the operator uses tape to bond the end of the plastic film to the outer wall of the non-woven fiber web roll; at this time, due to the upward movement of the take-up shaft, a gap is left between the non-woven fiber web roll on the take-up shaft and the second transmission belt for the plastic film roll to pass through;

[0034] The cam is pressed against the roller bearings and the roller bearings are pressed against the roller bearings to move the roller bearings upward, and the roller bearings are pressed against the roller bearings to move the roller bearings upward.

[0035] When the driving cylinder drives the flap to swing downward, the cutting blade on the lower surface of the flap can be embedded between adjacent transmission shafts to cut the non-woven fiber web, eliminating the need for manpower to cut the non-woven fiber web; at this time, the driving cylinder can achieve three functions: 1. Drive the cutting blade to cut the non-woven fiber web; 2. Drive the winding shaft to move upward so that a gap is left between the non-woven fiber web roll on the winding shaft and the second transmission belt for the plastic film roll to pass through; 3. Drive the slide seat to move upward so that the driving gear and the driven gear engage. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, a cutting blade 60541 is fixed to the lower surface of the flap 6054 by bolts, and the cutting blade 60541 is used to be embedded in the position between adjacent transmission shafts 236 when the flap 6054 swings downward; when the push plate 60511 pushes the extension shaft 271 upward to drive the pulley 251 to be embedded in the semicircular sleeve 63, the non-woven fiber web roll on the winding shaft 21 is raised and a gap is left between the non-woven fiber web roll and the transmission shaft 236 for the plastic film roll 51 to pass through.

[0053] Principle: After the non-woven fiber web is dried with hot air in the oven 1, the non-woven fiber web transmitted from the oven 1 can enter the first conveyor belt 3. At this time, the multiple wrapping covers 32 on the first bracket 31 are used. After the centrifugal fan 322 on the wrapping cover 32 works, the outside air can be brought into the wrapping cover 32, and the air ejected from the bottom of the multiple wrapping covers 32 can pass through the non-woven fiber web, thereby taking away the heat on the surface of the non-woven fiber web, and finally the non-woven fiber web after drying can be cooled, which is convenient for the subsequent winding and filming of the non-woven fiber web by the winding shaft 21;

[0054] When the nonwoven fiber web on the reel 21 is wound up, there is still a gap between the pulley 251 and the semicircular sleeve 63. At this time, the driving cylinder 6055 can also drive the push plate 60511 to swing upward when driving the push rod 6053 to swing upward. After the push plate 60511 swings upward, it can push the extension shaft 271, and then the extension shaft 271 can drive the pulley 251 and the reel 21 to move upward. At the same time, the operator holds the plastic film roll 51 by hand to control the position of the semicircular sleeve 63, and then the pulley 251 can be embedded in the semicircular sleeve 63. The operator then uses tape to bond the end of the plastic film to the outer wall of the nonwoven fiber web roll; at this time, due to the upward movement of the reel 21, a gap is left between the nonwoven fiber web roll on the reel 21 and the second transmission belt 23 for the plastic film roll 51 to pass through;

[0055] At this time, the pulley 251 is embedded in the semicircular sleeve 63, so the central axis of the take-up shaft 21 and the central axis of the winding shaft 5 are on the same straight line; at the same time, when the driving cylinder 6055 drives the push rod 6053 to swing upward, the push rod 6053 can contact the linkage shaft 601 and drive the slide 68 to move upward, and the slide 68 can drive the moving pulley 603 and the driving gear 602 to move upward, and the elastic belt 604 undergoes elastic deformation until the driving gear 602 and the driven gear 67 on the rotating shaft 66 are meshed. At the same time, after the elastic belt 604 is tightened, the driving motor 2 37 can drive the linkage shaft 601 to rotate through the driving pulley 238 and the elastic belt 604, and after the linkage shaft 601 rotates, the driving gear 602 and the driven gear 67 can drive the turntable 62 to rotate, and the turntable 62 can drive the winding shaft 5 to rotate through the angle arm 64, and then the winding shaft 5 can drive the plastic film roll 51 to rotate around the winding shaft 21; after the winding shaft 5 rotates around the winding shaft 21 for one circle, the plastic film can be quickly wrapped around the non-woven fiber web roll, and finally the packaging operation of the non-woven fiber web roll can be completed on the winding shaft 21;

[0056] When the piston rod of the driving cylinder 6055 moves upward to reset, the push rod 6053 and the push plate 60511 swing downward under their own gravity and then reset;

[0057] When the driving cylinder 6055 drives the flap 6054 to swing downward, the cutting blade 60541 on the lower surface of the flap 6054 is used, and the cutting blade 60541 can be embedded between adjacent transmission shafts 236 to cut the non-woven fiber web, and there is no need for manpower to cut the non-woven fiber web; at this time, the driving cylinder 6055 can achieve triple effects: 1. Drive the cutting blade 60541 to cut the non-woven fiber web; 2. Drive the winding shaft 21 to move upward so that a gap is left between the non-woven fiber web roll on the winding shaft 21 and the second transmission belt 23 for the plastic film roll 51 to pass through; 3. Drive the slide 68 to move upward so that the driving gear 602 and the driven gear 67 are engaged.
