Description

Technical Field

[0001] The invention relates to the technical field of shoe material film pasting, in particular to a supercritical fluid bead foaming shoe material film pasting device. Background Art

[0002] Supercritical fluid bead foaming technology is a process that uses supercritical fluid (such as supercritical carbon dioxide) as a foaming agent to prepare foaming materials. Under high temperature and high pressure environment, carbon dioxide has the properties of a fluid so that carbon dioxide in this state can enter the foaming material. When the pressure drops rapidly, the carbon dioxide gasifies, causing the foaming material to expand. This technology is also used in the manufacturing process of shoe upper materials.

[0003] Due to the presence of carbon dioxide gas in the inner wall of the upper material made by supercritical fluid bead foaming, during the hot pressing film lamination process, the carbon dioxide gas in the shoe material expands due to heat and causes the upper material to deform. Therefore, when hot pressing film lamination is performed, the supercritical fluid bead foamed shoe material is generally required to be preheated, and the temperature rise rate and temperature range need to be limited during the preheating process. Therefore, in order to ensure that the supercritical fluid bead foamed shoe material is laminated with a higher yield and higher efficiency, a supercritical fluid bead foamed shoe material lamination equipment is proposed.

[0061] Combine the following Figures 1 to 7 As shown, an embodiment of the present invention provides a supercritical fluid bead foaming shoe material film pasting device, comprising:

[0062] The platform 1 has two hot pressing components arranged on the top of the platform 1;

[0063] A power assembly, which is arranged on the top of the platform 1 and is connected to two hot pressing assemblies;

[0064] A heating component, which is arranged on the side wall of the platform 1 and is connected to the two hot pressing components;

[0065] Among them, the hot pressing components include:

[0066] A second heating seat 203, the second heating seat 203 is fixed on the top of the platform 1;

[0067] A plurality of connection components, wherein the plurality of connection components are arranged on the top of the platform 1;

[0068] A first heating seat 202, the first heating seat 202 is slidably connected to a plurality of connecting components;

[0069] A control component, which is disposed on the top of the first heating seat 202 and is connected to the power component. The control component is used to control the descending speed of the first heating seat 202;

[0070] The heating component includes:

[0071] A fixed plate 701, a diverter tank 702 is disposed on the top of the fixed plate 701, a buffer tank 703 is disposed on the bottom of the fixed plate 701, and the diverter tank 702 and the buffer tank 703 are connected;

[0072] Two second hoses 603, the two second hoses 603 are respectively connected to the two hot pressing components, and the two second hoses 603 are both connected to the diversion tank 702;

[0073] The heating mechanism is connected to the buffer tank 703 , and the heating mechanism is connected to the two hot pressing components. The heating mechanism is used to drive the heat transfer oil to circulate in the hot pressing component, the diversion tank 702 and the buffer tank 703 .

[0074] By means of the heating component, the heat transfer oil flows inside the hot pressing component, so as to heat the first heating seat 202 and the second heating seat 203, and cooperate with the power component to realize the hot pressing film laminating work of the supercritical fluid bead foam shoe material;

[0075] By controlling the operation of the control component, the two first heating seats 202 are made to descend at different speeds, so that the first heating seat 202 that descends faster performs the hot pressing film laminating operation, and the first heating seat 202 that descends slower performs the preheating treatment of the supercritical fluid bead foaming shoe material;

[0076] Through the diversion tank 702, the heating mechanism, and the buffer tank 703, when the heating mechanism is working, the high-temperature heat transfer oil first enters the first heating seat 202 and the second heating seat 203 for hot pressing and laminating, and after being diverted by the diversion tank 702, part of the heat transfer oil enters the preheated first heating seat 202 and the second heating seat 203. In this process, the preheating temperature can be changed by changing the amount of heat transfer oil entering the preheated first heating seat 202 and the second heating seat 203.

[0077] By controlling the component, the first heating seat 202 that is slowly lowered can gradually reduce the distance from the supercritical fluid bead foamed shoe material, thereby gradually increasing the temperature of the supercritical fluid bead foamed shoe material and ensuring the preheating effect.

[0078] Furthermore, the hot pressing assembly also includes:

[0079] Two heat exchange tubes 604, the two heat exchange tubes 604 are respectively arranged in the first heating seat 202 and the second heating seat 203;

[0080] A first hose 601, the first hose 601 is used to connect two heat exchange tubes 604, and the heat exchange tube 604 in the first heating seat 202 is connected to one of the second hoses 603;

[0081] The tube body 602 is connected to the heat exchange tube 604 in the second heating seat 203, and the tube body 602 is connected to the heating mechanism.

[0082] The heat transfer oil enters the heat exchange tube 604 in the second heating seat 203 through the tube body 602, then enters the heat exchange tube 604 in the first heating seat 202 through the first hose 601, and then enters the diversion tank 702 through the second hose 603. Through the diversion of the diversion tank 702, part of the heat transfer oil enters another hot pressing component, and the other part of the heat transfer oil enters the buffer tank 703.

[0083] Furthermore, the connection component includes:

[0084] The support rod 201 is fixed on the top of the platform 1 , and a connecting block 204 is slidably sleeved on the support rod 201 , and the connecting block 204 is fixed to the first heating seat 202 .

[0085] Furthermore, the hot pressing assembly also includes:

[0086] A plurality of sliders 206, wherein the plurality of sliders 206 are slidably connected to the plurality of support rods 201 in a one-to-one manner, a first spring 207 is fixed to the bottom of each slider 206, and each first spring 207 is fixed to the platform 1;

[0087] The metal plate 205 and the plurality of sliders 206 are fixed.

[0088] During the working process, the supercritical fluid bead foam shoe material is first placed on the metal plate 205. At this time, the metal plate 205 is between the first heating seat 202 and the second heating seat 203, thereby ensuring that the upper surface and the lower surface of the supercritical fluid bead foam shoe material can be evenly heated during the preheating process. Through the operation of the control component, the first heating seat 202 corresponding to the metal plate 205 descends slowly, and the supercritical fluid bead foam shoe material on the metal plate 205 is preheated until the first heating seat 202 pushes the metal plate 205 and the corresponding second heating seat 203 to fit together, and the preheating is completed. Then the first heating seat 202 rises. At this time, under the action of the first spring 207, the metal plate 205 is reset, and the hot melt adhesive film is placed on the preheated supercritical fluid bead foam shoe material. The first heating seat 202 descends again to perform the film pasting work.

[0089] Furthermore, the control component includes:

[0090] A support frame 401, the support frame 401 is fixed on the top of the platform 1, and a sleeve 402 is fixed through one side of the top of the support frame 401;

[0091] A piston 404, which is slidably disposed in the sleeve 402, and a sleeve rod 405 is disposed at the bottom of the piston 404;

[0092] The first flow valve 403 is disposed through the top of the sleeve 402 .

[0093] By controlling the first flow valve 403, the gas entering the sleeve 402 is slow, so that the piston 404 corresponding to the sleeve 402 descends slowly, so that the corresponding sleeve rod 405 descends slowly.

[0094] Furthermore, the power assembly includes:

[0095] A hydraulic push rod 301 is fixed to the bottom of the platform 1, and a telescopic end of the hydraulic push rod 301 passes through the top of the platform 1;

[0096] A transmission plate 302, the transmission plate 302 is fixed on the telescopic end of the hydraulic push rod 301, and two circular holes are formed on the top of the transmission plate 302;

[0097] Two connecting rods 303, the two connecting rods 303 are slidably disposed in the two circular holes, and the two connecting rods 303 are fixed to the two first heating seats 202 respectively;

[0098] Two connecting plates 304 are respectively fixed on the top of the two connecting rods 303 , and second springs 305 are fixed on the bottom of the two connecting plates 304 . The two second springs 305 are both fixed to the transmission plate 302 , and the two connecting plates 304 are respectively fixed to the two sleeve rods 405 .

[0099] Further, the heating mechanism comprises:

[0100] The tank body 501 has a heating plate 503 arranged horizontally in the tank body 501, a sealing ring is fixed to the side wall of the heating plate 503, and the sealing ring is in contact with the inner wall of the tank body 501, electric heating wires are embedded at the top and bottom of the heating plate 503, and the tank body 501 is filled with heat transfer oil, one of the tubes 602 passes through the top of the side wall of the tank body 501, and the other tube 602 passes through the bottom of the side wall of the tank body 501;

[0101] The electric push rod 502 is fixed on the top of the tank body 501 , and the telescopic end of the electric push rod 502 passes through the tank body 501 and is fixed on the heating plate 503 .

[0102] When the electric push rod 502 is working, it drives the heating plate 503 to rise or fall. With the action of the sealing ring, the heat transfer oil in the tank body 501 can enter one of the hot pressing components through the tube body 602 below when the heating plate 503 descends. When the heating plate 503 rises, the heat transfer oil in the tank body 501 enters another hot pressing component through the tube body 602 above.

[0103] Furthermore, it also includes:

[0104] Two one-way valves 706 are both set through the bottom of the buffer tank 703. Both one-way valves 706 are connected with a return pipe 707, one of which passes through the top of the side wall of the tank body 501, and the other returns The pipe 707 passes through the bottom of the side wall of the tank body 501.

[0105] Furthermore, it also includes:

[0106] The second flow valve 704 is arranged through the top of the side wall of the buffer tank 703 , and a connecting pipe 705 is arranged through the bottom of the side wall of the diversion tank 702 , and the connecting pipe 705 is communicated with the second flow valve 704 .

[0107] During the circulation of the heat transfer oil, when the heating plate 503 descends, the heat transfer oil in the buffer tank 703 enters the upper position of the tank body 501 through the upper return pipe 707 and the corresponding one-way valve 706. When the heating plate 503 rises, the heat transfer oil in the buffer tank 703 enters the lower position of the tank body 501 through the lower return pipe 707 and the corresponding one-way valve 706. In conjunction with the second flow valve 704, the amount of heat transfer oil entering the hot pressing assembly for preheating can be adjusted to control the preheating temperature.

[0108] The specific working method is: when in use, by controlling the two first flow valves 403, when one of the first flow valves 403 allows a larger flow rate of gas to pass through, the other first flow valve 403 allows a smaller flow rate of gas to pass through, and then the switch of the hydraulic push rod 301 is turned on. When the hydraulic push rod 301 works, it drives the two connecting plates 304 to descend through the transmission plate 302 and the second spring 305, and then drives the two connecting rods 303 to descend, so that the two first heating seats 202 are lowered;

[0109] Since the gas flow rate allowed to pass through one of the first flow valves 403 is relatively small, less gas enters the sleeve 402 corresponding to the first flow valve 403, so that the corresponding piston 404 and sleeve rod 405 descend more slowly, thereby achieving a speed difference in the descent of the two first heating seats 202, that is, when one of the first heating seats 202 has been attached to the corresponding metal plate 205 and the second heating seat 203, the other first heating seat 202 is still in a relatively slow descending state;

[0110] Therefore, when applying film to the shoe material, the supercritical fluid bead foamed shoe material is placed on one of the metal plates 205, and the first heating seat 202 corresponding to the metal plate 205 slowly descends during the heating process, so that the distance between the metal plate 205 and the corresponding first heating seat 202 is gradually reduced, so as to gradually increase the temperature of the supercritical fluid bead foamed shoe material, thereby preheating the supercritical fluid bead foamed shoe material, and then the transmission plate 302 is driven to rise by the hydraulic push rod 301, and then the hot melt adhesive film is placed on the preheated supercritical fluid bead foamed shoe material, and finally by The hydraulic push rod 301 drives the transmission plate 302 to descend, and the final hot pressing and laminating process of the shoe material is realized. Through the two hot pressing components, one of the hot pressing components can perform hot pressing and laminating while the other hot pressing component preheats the supercritical fluid bead foaming shoe material. When working next time, the shoe material after hot pressing and laminating in one of the hot pressing components is removed, and a new supercritical fluid bead foaming shoe material is placed, and the hot melt adhesive film is placed on the preheated supercritical fluid bead foaming shoe material in the other hot pressing component. Repeat the above work, and continuous preheating and laminating work can be performed;

[0111] During the operation of the hot pressing assembly, the switch of the electric heating wire on the heating plate 503 is turned on to heat the heat transfer oil in the tank body 501 to ensure that sufficient heat is provided during the hot pressing process. When the electric push rod 502 is working, the heating plate 503 is driven to move in the tank body 501. When the heating plate 503 descends, the heat transfer oil below the heating plate 503 enters the corresponding heat exchange tube 604 in the second heating seat 203 through the lower tube body 602, and then enters the corresponding heat exchange tube 604 in the first heating seat 202 through the first hose 601, and enters the diversion tank 702 through the corresponding second hose 603. After the heat transfer oil enters the diversion tank 702, the flow rate of the second flow valve 704 is adjusted, so that part of the heat transfer oil enters another group of hot pressing components through another second hose 603, and then flows back through another tube body 602 To the space above the heating plate 503 in the tank body 501, another part of the heat transfer oil enters the buffer tank 703 through the connecting pipe 705 and the second flow valve 704, and the hydraulic oil entering the buffer tank 703 enters the space above the heating plate 503 in the tank body 501 through the return pipe 707 and the corresponding one-way valve 706 at the top to realize the circulation of the heat transfer oil. In this process, the first heating seat 202 and the second heating seat 203 are heated by the high-temperature heat transfer oil and the heat exchange pipe 604 to provide heat for the preheating and heating operations. At the same time, through the control of the second flow valve 704, the amount of heat transfer oil entering the hot pressing assembly for preheating can be adjusted (the smaller the amount of heat transfer oil, the less heat it carries, and the lower the temperature of the first heating seat 202 and the second heating seat 203 used for preheating), thereby facilitating the control of the preheating temperature.
