Description

Technical Field

[0001] The invention relates to the technical field of leather production equipment, in particular to a slurry foaming device for producing space leather. Background Art

[0002] Space leather is a kind of artificial leather product. Space leather is made by coating water-based slurry on non-woven fabric and solidifying and ironing it, and then adding foaming agent slurry. After the slurry is foamed, it becomes a porous structure, which can increase softness and elasticity after foaming. It is then solidified, dried, washed, ironed, dried and finally rolled up.

[0003] In order to ensure the uniformity of the foaming slurry on the top of the non-woven fabric, a plate is set to push the foaming slurry back and forth while the foaming slurry moves back and forth within the width of the non-woven fabric. The plate pushes the foaming slurry to flow to ensure the uniform distribution of the foaming slurry, but two baffles are set on the outside to prevent the foaming slurry from flowing out along the edge of the non-woven fabric. When the plate moves near the baffle, the foaming slurry pushed by the front of the plate also continues to approach the baffle, and the foaming slurry finally collides with the baffle, causing the foaming slurry to overflow directly along the baffle, resulting in a waste of foaming slurry. Summary of the invention

[0004] The disclosed embodiment relates to a slurry foaming device for producing space leather, wherein a middle chain drives a middle slurry pipe, a horizontal slide and a middle guide plate to move back and forth, the middle slurry pipe performs a loading operation of water-based foaming slurry, and the middle guide plate drives the water-based foaming slurry to flow at the same time, so as to promote the water-based foaming slurry between the side limiting plates to remain uniform, and when the middle guide plate moves close to the side limiting plate, the lower convex strip pushes the tail of the middle guide plate to stop moving, and the tail of the middle guide plate no longer continues to approach the side limiting plate, and the amount of water-based foaming slurry pushed by the middle guide plate toward the side of the side limiting plate becomes smaller, thereby ensuring sufficient water-based foaming slurry near the opposite side limiting plate, avoiding the situation where the middle guide plate pushes the water-based foaming slurry close to the side limiting plate to cause overflow, and avoiding the situation where the foaming slurry overflows and wastes.

[0034] The upper part of the middle foaming frame 2 is fixedly provided with an upper support slide 3, the middle part of the upper support slide 3 is fixedly provided with a lower cross bar 301, the upper part of the upper support slide 3 is fixedly provided with an upper cross bar 302, the upper cross bar 302 is horizontally slidably provided with a horizontal slide 303, the middle part of the horizontal slide 303 is vertically penetrated and fixedly provided with a middle slurry pipe 304, the lower part of the horizontal slide 303 is rotatably provided with a middle guide plate 306, both sides of the middle guide plate 306 are fixedly provided with upper connecting springs 305, and the lower cross bar The middle displacement frame 4 is horizontally slidable on both sides of the upper part of 301, and the tail end of the upper connecting spring 305 is fixedly connected to the horizontal slide 303. The upper connecting spring 305 pulls the middle guide plate 306 and the moving direction of the horizontal slide 303 to maintain a vertical cross state. At this time, the pushing amount of the middle guide plate 306 to the water-based foaming slurry is at the maximum state. The middle displacement frame 4 is provided on both sides of the upper part of the upper supporting slide 3. The side of the middle displacement frame 4 is rotated with a driving wheel 401, and the middle displacement frame 4 is provided with a motor to drive the driving wheel 4 01 rotates, the middle displacement frame 4 is screwed at both ends of the middle threaded rod 402, the upper rotating shaft of the middle displacement frame 4 cooperates with the rotation of the upper support rod 403, the upper rotating shaft of the upper support rod 403 cooperates with the rotation to connect the upper lifting frame 404, the middle lower side of the upper lifting frame 404 rotates with the middle synchronous wheel 405, the driving wheel 401 is tightly engaged with the two sides of the middle chain 406, the middle part of the middle chain 406 is rotated and fixedly connected with the middle sliding column 407, and the rear side of the upper supporting slide 3 is provided with a slurry blocking plate 5 to block the slurry Side limiting plates 501 are fixed on both sides of the plate 5, and side lifting screws 502 are screwed on both ends of the slurry baffle plate 5. The lower end of the side lifting screw 502 is rotated with a side slide frame 504, and the upper end bevel gear of the side lifting screw 502 is meshed and connected with the bevel gears at the head and tail of the middle transmission shaft 503. The two side lifting screws 502 rotate at the same time to improve the lifting accuracy of the guide slurry baffle plate 5, avoid the situation where the guide slurry baffle plate 5 is tilted due to a single-sided side lifting screw 502, and ensure the consistency of the thickness of the water-based foaming slurry.

[0035] In the disclosed embodiment, the air supply pipe 104 is fixedly arranged on the inner side of the pre-drying oven 1, and the head end of the air supply pipe 104 is gradually narrowed toward the tail end. The narrowing of the tail end of the air supply pipe 104 can increase the wind speed. The air supply pipe 104 and the outlet air outlet 106 are located below the non-woven fabric 102. The temperature of the drying bellows 103 is lower than the hot air of the high-temperature drying equipment, which accelerates the solidification speed of the water-based foaming slurry on the surface of the non-woven fabric 102. The drying bellows 103 heats the water-based foaming slurry in advance, which reduces the cracking of the water-based foaming slurry due to excessively rapid temperature changes when it is directly dried at high temperature.

[0036] In the disclosed embodiment, lower ridges 307 are fixedly provided on the lower parts of both sides of the lower cross bar 301. When the middle guide plate 306 moves, the lower ridges 307 contact the middle guide plate 306, and the lower ridges 307 block the tail of the middle guide plate 306 from stopping movement. The lower ridges 307 push the middle guide plate 306 to tilt and rotate to one side, and the head end of the middle guide plate 306 continues to move close to the side limiting plate 501 with the horizontal slide 303, and the tail of the middle guide plate 306 no longer continues to approach the side limiting plate 501. The amount of water-based foaming slurry pushed by the middle guide plate 306 toward the side of the side limiting plate 501 becomes smaller, and the water-based foaming slurry near the side limiting plate 501 is kept sufficient, and the situation in which the middle guide plate 306 pushes too much water-based foaming slurry close to the side limiting plate 501 and overflows is avoided.

[0037] In the disclosed embodiment, the head and tail ends of the middle threaded rod 402 are rotatably connected to the upper supporting slide 3, the upper lifting frame 404 is vertically slidably connected to the lower cross bar 301, the middle sliding column 407 is vertically slidably connected to the horizontal slide 303, the middle synchronous wheel 405 is meshed with the upper inner side of the middle chain 406, and when the middle threaded rod 402 rotates in a circular direction, the middle displacement frames 4 at both ends of the middle threaded rod 402 move in opposite directions, the upper lifting frame 404 and the middle synchronous wheel 405 move up synchronously, and the upper lifting frame 404 supports the middle part of the middle chain 406 to move up through the middle synchronous wheel 405, so that the middle chain 406 remains in a tightened state, so that the middle chain 406 drives the middle slurry pipe 304, the horizontal slide 303 and the middle guide plate 306 to shorten the reciprocating movement distance, and the slurry baffle 5 is replaced with a narrower model to reduce the width of the slurry of the non-woven fabric 102, and the slurry width of the non-woven fabric 102 is adjusted according to production needs.

[0038] In the disclosed embodiment, the lower convex strip 307 is located on the inner side of the side flow limiting plate 501, the bottom of the side flow limiting plate 501 is in contact with the non-woven fabric 102, the non-woven fabric 102 is located below the slurry baffle plate 5 and the middle guide plate 306, the horizontal slide 303 is located between the side flow limiting plates 501 on both sides of the slurry baffle plate 5, the lower end of the side slide trough frame 504 is fixedly connected to the middle foaming frame 2, the horizontal slide 303 moves between the two side flow limiting plates 501, and the middle slurry pipe 304 is loaded with water-based foaming slurry during movement, thereby achieving uniform spreading of the slurry on both sides of the non-woven fabric 102.

[0039] Embodiment 2, on the basis of embodiment 1, the head end of the side flow limiting plate 501 and the slurry baffle plate 5 are fitted and slid together, the lower convex strip 307 is fixed on the inner side of the side flow limiting plate 501, the upper part of the side flow limiting plate 501 and the middle displacement frame 4 are fixed, the side flow limiting plate 501 is displaced along with the middle displacement frame 4, so as to adjust the width of the water-based foaming slurry gathered in the middle, and adjust the feeding width of the water-based foaming slurry, thereby eliminating the replacement process of the side flow limiting plate 501 and the slurry baffle plate 5.

[0040] The working principle of this embodiment is as follows: a non-woven fabric 102 having a layer of water-based material is introduced along the cloth guide roller 101 of the middle foaming frame 2, and the non-woven fabric 102 passes under the slurry retaining plate 5. The interval between the slurry retaining plate 5 and the non-woven fabric 102 is the thickness of the water-based foaming slurry. The thread of the side lifting screw 502 guides the slurry retaining plate 5 to move along the side slide frame 504 to adjust the height, and the side lifting screws 502 at both ends of the guiding slurry retaining plate 5 are synchronously rotated through the middle transmission shaft 503. The two side lifting screws 502 rotate at the same time to improve the lifting accuracy of the guiding slurry retaining plate 5, so as to avoid the situation that the guiding slurry retaining plate 5 is tilted due to the unilateral side lifting screw 502, resulting in inconsistent thickness of the water-based foaming slurry. The middle slurry pipe 304 is connected to the pump of the water-based foaming slurry, and the middle slurry pipe 304 is facing the front side of the slurry retaining plate 5 for perfusion of the water-based foaming slurry;

[0041] The motor of the middle displacement frame 4 drives the driving wheel 401 to rotate, and the driving wheel 401 drives the middle chain 406 to rotate. The middle chain 406 rotates in a circle, and the middle chain 406 drives the horizontal slide 303 to move synchronously through the middle slide column 407. The vertical slide groove of the horizontal slide 303 adapts to the height change of the middle slide column 407. The horizontal slide 303 moves horizontally along the upper cross bar 302, and the middle slurry pipe 304 and the horizontal slide 303 and the middle guide plate 306 move horizontally and reciprocatingly synchronously. The horizontal slide 303 moves in the space between the two side limiting plates 501. The middle slurry pipe 304 is moving to load the water-based foaming slurry to ensure the uniform spreading of the slurry on both sides of the non-woven fabric 102. The middle guide plate 306 can also simultaneously drive the water-based foaming slurry between the front side of the slurry baffle 5 and the two side limiting plates 501 to flow. The side limiting plates 501 The middle guide plate 306 moves toward the side restrictor 501, and the middle guide plate 306 contacts the lower convex strip 307 first. The lower convex strip 307 pushes the tail of the middle guide plate 306 to stop moving. The head of the middle guide plate 306 continues to move toward the side restrictor 501 along with the horizontal slide 303. The tail of the middle guide plate 306 no longer continues to approach the side restrictor 501. The middle guide plate 306 tilts and rotates toward the other side. The amount of water-based foaming slurry pushed by the middle guide plate 306 toward the side restrictor 501 becomes smaller, ensuring sufficient water-based foaming slurry near the opposite side restrictor 501, and avoiding the situation where the middle guide plate 306 pushes the water-based foaming slurry close to the side restrictor 501 to cause overflow, thereby avoiding the waste caused by the overflow of the foaming slurry.

[0042] The threads at both ends of the middle threaded rod 402 guide the middle displacement racks 4 to move towards each other, and the two middle displacement racks 4 move towards each other along the lower cross bar 301. The driving wheels 401 on both sides of the middle chain 406 move towards each other as the middle displacement rack 4 moves, thereby shortening the width of the middle chain 406. While the middle displacement racks 4 move towards each other, the upper lifting rack 404 is pushed upward through the upper support rod 403. The upper lifting rack 404 supports the middle part of the middle chain 406 to move upward through the middle synchronous wheel 405 to ensure the tightness of the middle chain 406, thereby achieving The middle chain 406 drives the middle slurry pipe 304, the horizontal slide 303 and the middle guide plate 306 to shorten the reciprocating distance. At the same time, the slurry baffle 5 is replaced with a narrower model to reduce the width of the non-woven fabric 102 slurry. The middle displacement frame 4 moves away from each other, and the width of the middle chain 406 is expanded, thereby expanding the width of the non-woven fabric 102 slurry. The slurry width of the non-woven fabric 102 is adjusted according to production needs, and the disassembly process of the middle chain 406 and other components is eliminated, and the adjustment is faster.

[0043] After the non-woven fabric 102 is coated with the water-based foaming slurry, the non-woven fabric 102 enters the pre-drying oven 1 along the cloth guide roller 101, and the hot air from the drying bellows 103 is discharged toward the non-woven fabric 102 through the upper air outlet 105 of the air supply pipe 104, so as to promote the pre-drying and heating operation of the water-based foaming slurry of the non-woven fabric 102. Then, when the non-woven fabric 102 enters the subsequent high-temperature drying equipment, the temperature of the drying bellows 103 is lower than the hot air of the high-temperature drying equipment, so as to accelerate the solidification speed of the water-based foaming slurry on the surface of the non-woven fabric 102, and the drying bellows 103 heats the water-based foaming slurry in advance to prevent the water-based foaming slurry from cracking during the subsequent high-temperature drying. Then, the non-woven fabric 102 is washed, ironed, dried and finally rolled up. Space leather is mainly used in sports shoes, and also serves the clothing, shoemaking, luggage, car and train carriage decoration, furniture and other industries.
