Description

Technical Field

[0001] This invention relates to the field of sponge foaming equipment technology, specifically to a foaming equipment for sponge production. Background Technology

[0002] Sponge is a type of polyurethane foam, belonging to the category of soft polyurethane foam. Due to its porous honeycomb structure, it possesses excellent softness, elasticity, water absorption, and water resistance, and is commonly used in shoe materials. A continuous sponge foaming production line is one of the core pieces of equipment in sponge production. Most production lines use chain-plate conveyors to form foaming molding tanks, mainly including side chain conveyors, bottom conveyor belt modules, film conveyor modules, kraft paper conveyor modules, and coating pipes. A film is laid on the surface of the side chain conveyor, and kraft paper is laid on the bottom conveyor belt module, thus forming a continuous sponge foaming molding tank. During molding, materials A and B are transported to the mixing head via a high-pressure metering pump and mixed at high speed through impact. The mixed liquid raw materials are then evenly spread onto the moving kraft paper through the coating die head for foaming. Baffles on both sides of the tank limit the width of the sponge, and the bottom conveyor belt module drives the raw materials forward at a uniform speed. The foamed sponge enters the curing tunnel with the conveyor belt to complete secondary cross-linking, and finally, it is cut into sponge blocks of specified sizes by the cutting system.

[0003] However, when using existing foaming equipment for sponge production, the kraft paper is prone to wrinkles during the laying process. This causes the bottom of the sponge to stick to the kraft paper after foaming, resulting in wrinkles or even damage to the kraft paper that gets mixed into the sponge, affecting the quality of sponge production.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-9This invention provides a foaming device for sponge production, comprising a main body; the main body includes a moving module 104, a slider 106 connected to the moving module 104, and a coating pipe 105 connected to the slider 106; the main body also includes a base plate 101, a shell 102, a bottom conveyor belt module 103, a side chain conveyor 107, a film conveying module 108, and a kraft paper conveying module 109, all of which are well-known technologies in this field and will not be described in detail here; the main body also includes a flattening and coating mechanism for flattening the kraft paper and applying a release agent; The spreading and coating mechanism includes two movable plates 1103 and a moving mechanism for driving the movable plates 1103 to move; the spreading and coating mechanism also includes a lifting cover 1101, a sponge block 1102 connected to the lifting cover 1101, and a lifting mechanism connecting the lifting cover 1101 and the movable plates 1103; the spreading and coating mechanism also includes a first liquid storage tank 1104, a first metal plate 1106 sliding in the first liquid storage tank 1104, and a hose 1105 connecting the first liquid storage tank 1104 and the lifting cover 1101, the first liquid storage tank 1104 being fixed to the base plate 101. The spreading and coating mechanism also includes a solenoid valve 1107 connected to the hose 1105; the first storage tank 1104 is filled with a release agent. During foaming, before the coating tube 105 applies the foaming material to the kraft paper surface, the moving mechanism can drive two moving plates 1103 to slide away from each other. At the same time, the lifting mechanism drives two lifting covers 1101 to move away from each other, so that the two sponge blocks 1102 slide away from each other along the surface of the kraft paper, enabling a spreading operation. At the same time, the solenoid valve 1107 is opened. At this time, in the first metal... Under the influence of gravity, the release agent temporarily stored in the first liquid storage tank 1104 is squeezed and enters the lifting cover 1101 through the solenoid valve 1107 and the hose 1105. It is then applied to the surface of the kraft paper through the sponge block 1102, thus enabling automatic application during the laying process. When the two lifting covers 1101 move closer to each other, the lifting mechanism moves them upward and separates the sponge block 1102 from the kraft paper, avoiding wrinkles in the kraft paper, ensuring the laying effect, and thus ensuring the quality of foaming and the quality of sponge production.

[0029] The moving mechanism includes two support blocks 201 and two first guide rods 202 inserted into the side walls of the support blocks 201; a moving plate 1103 is sleeved on the side walls of the first guide rods 202; the moving mechanism also includes two first push plates 207, a connecting block 205 connected to the first push plates 207, and a first spring telescopic rod 204 connected to the bottom of the connecting block 205, the lower end of the first spring telescopic rod 204 being connectable to the frame of the kraft paper conveying module 109; the moving mechanism also includes a sloping groove 206 formed in the side wall of the first push plate 207, a first push pin 203 connected to the moving plate 1103, and a first push mechanism for lifting and lowering the first push plate 207; the first push pin 203 slides in the sloping groove 206, and pushes the first push plate 207 downward through the first push mechanism, and the first spring telescopic rod 204... 04 is compressed, causing the first push pin 203 to slide upward along the inclined groove 206, thereby pushing the two moving plates 1103 to slide away from each other on the first guide rod 202. At the same time, the lifting mechanism drives the two lifting covers 1101 to move away from each other, so that the two sponge blocks 1102 slide away from each other along the surface of the kraft paper, enabling a flat laying operation. Furthermore, the first push plate 207 can move upward and reset under the action of the first spring telescopic rod 204, driving the first push pin 203 to slide downward along the inclined groove 206, thereby pushing the two moving plates 1103 to move closer to each other along the first guide rod 202, and driving the two lifting covers 1101 to move closer to each other through the lifting mechanism, facilitating the movement of the two lifting covers 1101 towards and away from each other, ensuring the synchronous effect of the movement.

[0030] The first pushing mechanism includes multiple first triangular blocks 302, a first connecting frame 301 connecting the first triangular blocks 302 and the first pushing plate 207, and a pushing rod 303 connected to the slider 106. The pushing rod 303 can slide on the side wall of the first triangular block 302. The diameter and strength of the pushing rod 303 are sufficient to ensure that it will not deform. When the slider 106 reciprocates, it can drive the pushing rod 303 to move synchronously. When the pushing rod 303 abuts against the side wall of the first triangular block 302, it can push the first triangular block 302 to move downward. At the same time, the first connecting frame 301 drives the two first pushing plates 207 to move downward. The first spring telescopic rod 204 is compressed. When the pushing rod 303 passes the first triangular block 302, the first pushing plate 207 can move upward and reset under the action of the first spring telescopic rod 204. The movement of the slider 106 and the coating tube 105 can be used as power to realize the lifting and lowering of the first pushing plate 207, which is more convenient and faster and does not require an additional drive module.

[0031] The lifting mechanism includes a second spring telescopic rod 401 connected between the moving plate 1103 and the lifting cover 1101, a first push block 402 connected to the lifting cover 1101, and a second push block 404 connected to the support block 201. The first push block 402 includes a first inclined surface 403, allowing the second push block 404 to slide on the first inclined surface 403. The lifting mechanism also includes a limiting mechanism for limiting the lifting cover 1101. When the two lifting covers 1101 are in contact, the sponge block 1102 can abut against the surface of the kraft paper under the action of the second spring telescopic rod 401. When the two lifting covers 1101 move away from each other, when the first inclined surface 403 of the first push block 402 abuts against the second push block 404, the lifting cover 1101 can be pushed upward and limited by the limiting mechanism, so that a distance is created between the sponge block 1102 and the kraft paper, and the solenoid valve 1107 is closed, making it easy to move the lifting cover 1101 upward without the need for an additional drive module.

[0032] The limiting mechanism includes a mounting cover 502 connected to the movable plate 1103, a movable block 507 sliding within the mounting cover 502, and a third spring telescopic rod 505 connecting the movable block 507 and the mounting cover 502. The limiting mechanism also includes multiple second triangular blocks 503 connected to the movable block 507 and a pusher frame 501 connected to the lifting cover 1101. Each second triangular block 503 includes a second inclined surface 504, allowing the pusher frame 501 to slide on the second inclined surface 504. The limiting mechanism also includes a second push pin 506 connected to the movable block 507. When the lifting cover 1101 moves upward, the second spring telescopic rod 501 is compressed, causing the pusher frame 501 to move upward and slide upward along the second inclined surface 504, thus pushing the second triangular blocks 507. 3. The moving block 507 moves, and the third spring telescopic rod 505 is compressed. When the pushing frame 501 passes the second triangular block 503, the pushing frame 501 can abut against the top of the second triangular block 503, thereby limiting the pushing frame 501 and thus limiting the lifting cover 1101. When the two lifting covers 1101 move closer to each other, when the ends of the two second pushing pins 506 abut against each other, the moving block 507 can be pushed to move. The third spring telescopic rod 505 is compressed, so that the pushing frame 501 is separated from the second triangular block 503 and is no longer limited. This allows the lifting cover 1101 to move downward and reset under the action of the second spring telescopic rod 401 and abut against the kraft paper, so that the two lifting covers 1101 fit together, thereby ensuring continuous flat laying operation.

[0033] The main body of the device also includes adsorption mechanisms set on both sides of the bottom conveyor belt module 103; the adsorption mechanism includes two suction hoods 601 connected to the bottom conveyor belt module 103 and multiple adsorption holes 602 opened on the top of the suction hoods 601; the adsorption mechanism also includes a fan 604 and an exhaust pipe 603 connecting the suction hoods 601 and the fan 604. When the fan 604 is started, air is drawn from the suction hoods 601 through the exhaust pipe 603, and then the air is drawn through the adsorption holes 602, so that the flat kraft paper can be adsorbed on the suction hoods 601 and a suitable adsorption force is ensured, so as to ensure its normal conveying and avoid edge curling and displacement, so as to improve the flatness effect, ensure the quality of foaming, and thus ensure the quality of sponge production.

[0034] The main body of the device also includes a vibration mechanism for striking and vibrating the bottom of the kraft paper; the vibration mechanism includes a support platform 704, a chamber 701 opened in the support platform 704, and a lifting plate 703 sliding in the chamber 701; the vibration mechanism also includes multiple vibration rods 702 connected to the lifting plate 703 and a drive mechanism for driving the lifting plate 703 to move up and down. The upper end of the vibration rod 702 is set through the top of the support platform 704, and the vibration rod 702 is made of rubber. The drive mechanism drives the lifting plate 703 and the vibration rod 702 to move up and down reciprocally. In this reciprocating motion, the vibration rod 702 can strike and vibrate the bottom of the kraft paper, forming a high-frequency, low-amplitude vibration. Since the foaming raw materials are coated on the kraft paper after mixing, they are prone to trapping air and forming large-diameter bubbles. The high-frequency, low-amplitude vibration can make the large-diameter bubbles formed by the air rise and burst quickly, reducing the voids and bulges inside the sponge, ensuring and improving the quality of sponge foaming, and thus ensuring the quality of sponge production.

[0035] The driving mechanism includes a second liquid storage tank 801 connected to the support platform 704 and a connecting pipe 802 connecting the second liquid storage tank 801 and the chamber 701; the driving mechanism also includes a second metal plate 803 sliding within the second liquid storage tank 801 and a lifting assembly for driving the second metal plate 803 to move up and down; the second liquid storage tank 801 is filled with hydraulic oil; the lifting assembly includes an L-shaped block 804 connected to the second metal plate 803 and a second push plate 805 connected to the connecting block 205; the second push plate 805 is located below the L-shaped block 804 and can abut against it; when the first push plate 207 moves up and down, it can drive the second push plate 805 to move up and down synchronously through the connecting block 205; when the second push plate 805 moves downward, it gradually disengages from the L-shaped block 804. At this time, the second metal plate 803 can move downward along the second liquid storage tank 801 under the action of gravity and squeeze the hydraulic oil in the second liquid storage tank 801. Under the action of hydraulic pressure, it can push the lifting plate 703 to move upward by the vibration rod 702. When the second push plate 805 moves upward, it can drive the L-shaped block 804 and the second metal plate 803 to move upward. At this time, the vibration rod 702 and the lifting plate 703 can move downward to reset. The lifting plate 703 and the vibration rod 702 can be lifted and lowered by the lifting of the first push plate 207, which is more convenient and faster. In addition, the setting of the second metal plate 803 can ensure that the squeezing force of the vibration rod 702 on the kraft paper is constant, ensuring the vibration effect while avoiding lifting or damaging the kraft paper.

[0036] The main body of the device also includes a leveling and extrusion mechanism for leveling and extruding the foaming material on the kraft paper; the leveling and extrusion mechanism is connected to the outer shell 102 and located above the bottom conveyor belt module 103; the leveling and extrusion mechanism includes a V-shaped plate 901, a pressure plate 903 connected to the V-shaped plate 901, and a pressure control mechanism for extruding the V-shaped plate 901; the V-shaped plate 901 includes a third inclined surface 902. After vibration is completed, when the foaming material abuts against the third inclined surface 902 of the V-shaped plate 901, it can push the V-shaped plate 901 and the pressure plate 903 to move upward. Under the action of the pressure control mechanism, the extrusion pressure of the V-shaped plate 901 and the pressure plate 903 on the foaming material is kept constant, which facilitates leveling and extruding the foaming material, allowing the material to be uniformly compacted during flow. At the same time, the V-shaped design facilitates the extrusion of large-diameter air bubbles entrained in the material and can guide them to be discharged to both sides.

[0037] The pressure control mechanism includes a second connecting frame 1002 connected to the V-shaped plate 901, a third guide rod 1001 connected to the second connecting frame 1002, and a third metal plate 1003 connected to the second connecting frame 1002. The lower end of the third guide rod 1001 can be fixed to the top of the outer shell 102. The third metal plate 1003 is sleeved on the side wall of the third guide rod 1001, and the third guide rod 1001 is fixed to the top of the outer shell 102. When the foaming material abuts against the third inclined surface 902 of the V-shaped plate 901, it can push the V-shaped plate 901 and the pressure plate 903 to move upward. At the same time, it pushes the second connecting frame 1002 and the third metal plate 1003 to move upward. When the foaming material is delivered to the bottom of the pressure plate 903, under the action of the third metal plate 1003, a constant extrusion pressure can be applied to the foaming material to ensure the effect of extrusion and leveling.

[0038] Working principle: During use, the bottom conveyor belt module 103 and the side chain plate conveyor 107 are started for conveying. At the same time, the kraft paper conveying module 109 is started, so that the kraft paper is conveyed on the bottom conveyor belt module 103. The film conveying module 108 is started, so that the film is conveyed with the side chain plate conveyor 107. Meanwhile, the A material and B material of the foaming equipment are first fully mixed in the mixing head. The mixed foaming material is then conveyed to the surface of the moving kraft paper through the coating pipe 105. The moving module 104 drives the slider 106 and the coating pipe 105 to move back and forth to ensure uniform material supply. The foaming material is conveyed along with the kraft paper.

[0039] When the slider 106 reciprocates, it drives the push rod 303 to move synchronously. When the push rod 303 abuts against the side wall of the first triangular block 302, it pushes the first triangular block 302 downward. At the same time, the first connecting frame 301 drives the two first push plates 207 to move downward, the first spring telescopic rod 204 is compressed, and the first push pin 203 slides upward along the inclined groove 206, thereby pushing the two moving plates 1103 to slide away from each other on the first guide rod 202. At the same time, the lifting mechanism drives the two lifting covers 1101 to move away from each other, so that the two sponge blocks 1102 slide away from each other along the surface of the kraft paper, enabling a flat laying operation.

[0040] Simultaneously, the solenoid valve 1107 is opened. At this time, under the gravity of the first metal plate 1106, the release agent temporarily stored in the first liquid storage tank 1104 is squeezed and enters the lifting cover 1101 through the solenoid valve 1107 and the hose 1105. It is then applied to the surface of the kraft paper through the sponge block 1102, thus enabling automatic application during the laying process, which is more convenient and faster, and can improve the quality of subsequent foaming. When the first inclined surface 403 abuts against the second pushing block 404, it can push the lifting cover 1101 to move upward. At the same time, the second spring... The spring telescopic rod 401 is compressed, which drives the push frame 501 to move upward and causes the push frame 501 to slide upward along the second inclined plane 504, which can push the second triangular block 503 and the moving block 507 to move. The third spring telescopic rod 505 is compressed. When the push frame 501 passes the second triangular block 503, the push frame 501 can abut against the top of the second triangular block 503, thereby limiting the push frame 501 and limiting the lifting cover 1101, so that a distance is created between the sponge block 1102 and the kraft paper, and the solenoid valve 1107 is closed.

[0041] When the push rod 303 passes the first triangular block 302, the first push plate 207 can move upward and reset under the action of the first spring telescopic rod 204, which can drive the first push pin 203 to slide downward along the inclined groove 206, thereby pushing the two moving plates 1103 to move closer to each other along the first guide rod 202, and driving the two lifting covers 1101 to move closer to each other through the lifting mechanism. At this time, since there is a distance between the sponge block 1102 and the kraft paper, wrinkles in the kraft paper can be avoided, ensuring the flat laying effect and improving the quality of sponge foaming. When the ends of the two second push pins 506 abut together, they can push the moving block 507 to move, and the third spring telescopic rod 505 is compressed, causing the push frame 501 to disengage from the second triangular block 503 and no longer limit it, so that the lifting cover 1101 can move downward and reset under the action of the second spring telescopic rod 401 and abut against the kraft paper, and make the two lifting covers 1101 fit together, thereby ensuring continuous flat laying operation.

[0042] At the same time, the blower 604 is started, and the suction hood 601 is drawn through the exhaust pipe 603. Then, the suction operation is carried out through the adsorption hole 602, so that the flat kraft paper can be adsorbed on the suction hood 601 and a suitable adsorption force is ensured. This ensures normal transportation while avoiding edge curling and displacement, resulting in better flatness, ensuring foaming quality, and thus ensuring the quality of sponge production.

[0043] When the first push plate 207 rises and falls, it can drive the second push plate 805 to rise and fall synchronously through the connecting block 205. When the second push plate 805 moves downward, it gradually disengages from the L-shaped block 804. At this time, the second metal plate 803 can move downward along the second liquid storage tank 801 under the action of gravity and squeeze the hydraulic oil in the second liquid storage tank 801. Under the action of hydraulic pressure, it can push the lifting plate 703 to move upward by the vibration rod 702. When the second push plate 805 moves upward, it can drive the L-shaped block 804. As the second metal plate 803 moves upward, the vibrating rod 702 and the lifting plate 703 can move downward to reset. By repeating this process, the vibrating rod 702 can reciprocate to strike the bottom of the kraft paper, generating high-frequency, low-amplitude vibration. Since the foaming raw materials are coated on the kraft paper after mixing, they are prone to trapping air and forming large-pore bubbles. The high-frequency, low-amplitude vibration can cause the large-pore bubbles formed by the air to rise and burst quickly, reducing voids and bulges inside the sponge, ensuring and improving the quality of sponge foaming, and thus ensuring the quality of sponge production.

[0044] After vibration is complete, when the foaming material comes into contact with the third inclined surface 902 of the V-shaped plate 901, it can push the V-shaped plate 901 and the pressure plate 903 to move upward. At the same time, it pushes the second connecting frame 1002 and the third metal plate 1003 to move upward. When the foaming material is delivered to the bottom of the pressure plate 903, under the action of the third metal plate 1003, a constant extrusion pressure can be applied to the foaming material, which facilitates the leveling and extrusion of the foaming material, allowing the material to be uniformly compacted during flow. At the same time, the V-shaped design facilitates the extrusion of large-diameter air bubbles entrained in the material and can guide them to be discharged to both sides.
