Description

Technical Field

[0001] The present invention relates to the field of shoe-making machinery, and in particular to a device and method for making mixed-color soles. Background Art

[0002] There are many types of sole materials, which can be divided into natural sole materials and synthetic sole materials. Natural sole materials include natural sole leather, bamboo, wood, etc., and synthetic sole materials include rubber, plastic, rubber-plastic composite materials, recycled leather, elastic cardboard, etc. With the development of the times, people have a deeper understanding of clothing matching. A pair of suitable shoes is the finishing touch of matching. Major manufacturers will design different uppers and shoe shapes to cater to consumers, and even start designing the soles.

[0003] The problems of the prior art are as follows: the sole design under the prior art generally changes the pattern of the sole. Due to the structural limitations of the sole and out of consideration for the performance of the shoe, generally only the color of the sole is changed. When making mixed-color soles in the prior art, the base color pulp is first poured on the chopping board, and then the mixed-color pulp is sprinkled on the specific position of the base color pulp as required. The base color pulp at the specific position will be mixed with the mixed-color pulp to collide with different colors, thereby achieving a mixed-color effect of the sole. However, this method is time-consuming and labor-intensive and requires manual operation. Moreover, manual operation often causes the mixed-color pulp to fail to be sprinkled on the specific position of the base color pulp as required due to hand shaking or external force.

DETAILED DESCRIPTION

[0019] In order to further explain the technical solution of the present invention, it is described in detail below through specific embodiments.

[0020] like Figure 1 , 2As shown, the present invention provides a device for making mixed-color soles, including a machine 1 and a mixing nozzle structure 10. The machine 1 is used as a working platform for installation, support and connection, and provides a support platform required for work. A control panel 2 is arranged at the front end of the machine 1. The control panel 2 processes the edited program and controls the X-axis track 7, the Y-axis track 3 and the Z-axis track 8, so that the mixing nozzle structure 10 can be moved to a suitable position to spray the mixed material on the mold 4. The top of the machine 1 is provided with a Y-axis track 3, and the top of the Y-axis track 3 is provided with a mold 4. The mold 4 is used to hold the mixed material after the A material, the B material and the additive are mixed. The left and right sides of the machine 1 are symmetrically provided with pillars 5, and the pillars 5 are used for supporting and connecting , and a horizontal plate 6 is arranged on the top of the inner side of the two pillars 5, the horizontal plate 6 is used to install the X-axis track 7 and provide support for movement in the X-axis direction, the front end of the horizontal plate 6 is slidably installed with the X-axis track 7, the front end of the X-axis track 7 is slidably installed with the Z-axis track 8, the front end of the Z-axis track 8 is provided with a mounting structure 9, the mounting structure 9 is used to install one or more mixing nozzle structures 10, the X-axis track 7, the Y-axis track 3, and the Z-axis track 8 are all connected to the control panel 2 by electrical signals. When working, through a pre-set program, the control panel 2 will issue movement instructions to the X-axis track 7, the Y-axis track 3, and the Z-axis track 8, and through the cooperation of an external pump, the mixing nozzle structure 10 can be moved to a suitable position to spray the mixed material on the mold 4; As shown in Figs. 4, 5 and 6, at least one mixing nozzle structure 10 is embedded and installed in the mounting structure 9 of the present invention. The color mixing nozzle structure 10 is externally connected to a pump machine for material A, material B and an additive. One end of the pump machine is connected to a barrel filled with material A, material B and an additive, and the other end is connected to the color mixing nozzle structure 10, so that material A, material B and the additive in the barrel are pumped into the color mixing nozzle structure 10, so that the color mixing nozzle structure 10 can stir and mix them to form a mixture and spray it on the mold 4. At the same time, an air gun is externally connected to the tube body 103 in the color mixing nozzle structure 10. After the step of spraying the mixture is completed, the color mixing nozzle structure 10 starts the air gun to blow the mixture so that the mixture presents a specified texture pattern in the mold 4. The mixing nozzle structure 10 includes a docking joint 101, which is used to connect to the pump machine for material A, material B and an additive. The pump machine connected, the joint 101 is set through the top of the nozzle cover 102, the nozzle cover 102 is used for installation and connection, and the bottom of the nozzle cover 102 is embedded with a tube body 103. The tube body 103 is used for an external air gun, and it temporarily stores material A, material B and additives and provides a channel for the mixed material to be sprayed out. The tube body 103 is embedded in the installation and installation structure 9, and a detachable nozzle 104 is installed at the bottom of the tube body 103. The detachable nozzle 104 is used to change the state of the mixed material spraying. If a plurality of through holes are set in the detachable nozzle 104, the mixed material formed by the material A, material B and additives will be sprayed out in all directions. If only a single through hole is set at the bottom of the detachable nozzle 104, the mixed material will be sprayed out in a straight line along the through hole. Through the detachable nozzle 104, different mixed color soles can be customized according to different requirements of customers; Among them, a mounting thread 103A is provided at the bottom inner of the tube body 103, and the tube body 103 is installed in cooperation with the top of the detachable nozzle 104 through the mounting thread 103A. The thread head 104A of the detachable nozzle 104 is threadedly connected with the mounting thread 103A at the bottom of the tube body 103. The threaded cooperation has the advantages of simple maintenance, low cost and easy disassembly, which makes it convenient for the staff to replace different nozzles at the bottom of the tube body 103 to achieve different color mixing effects.

[0021] like Figure 5 , 8As shown, a stirring screw 105 is vertically placed inside the tube body 103 of the present invention. The stirring screw 105 is used to stir the material A, material B and auxiliary agents pumped into the tube body 103 to mix the three. The stirring screw 105 includes a round rod 105A and a stirring blade 105B. The round rod 105A is used for installation and connection. The round rod 105A is vertically placed inside the tube body 103, and the spiral array on the outer side of the round rod 105A is provided with stirring blades 105B. The material A, material B and auxiliary agents are pumped into the docking joint 101 through a pump and then enter the tube body 103. The pumped material A, material B and auxiliary agents will carry a certain amount of power, which will act on the stirring blades 105B arranged in the spiral array on the outer side of the round rod 105A, pushing the stirring blades 105B and the round rod 105A to rotate. The material A, material B and auxiliary agents will rotate together driven by the stirring blades 105B and the round rod 105A to achieve stirring and form a mixture.

[0022] like Figure 7 As shown, the detachable spray head 104 of the present invention comprises a threaded head 104A, a spray pipe 104B is arranged at the bottom of the threaded head 104A, a nozzle 104C is arranged at the bottom of the nozzle 104B, the threaded head 104A, the spray pipe 104B and the nozzle 104C are internally connected, and the spray pipe 104B and the nozzle 104C are installed at the bottom of the tube body 103 through the threaded head 104A and the installation thread 103A. When working, the mixed material A, material B and the additive will form a mixed material, which will be pumped from the tube body 103 into the threaded head 104A, then flow into the spray pipe 104B, and then pass through the nozzle 104C. The mixture is sprayed out. By changing the shape or structure of the nozzle 104C, the state of the mixture sprayed from the nozzle 104C will be different. For example, a single through hole is set at the bottom, and the mixture will be sprayed out in a straight line along the through hole. Different mixed color soles can be customized according to different requirements of customers through the detachable nozzle 104. The threaded head 104A of the detachable nozzle 104 is threadedly connected with the installation thread 103A at the bottom of the tube body 103. The threaded connection has the advantages of simple maintenance, low cost and easy disassembly, which is convenient for the staff to replace different nozzles at the bottom of the tube body 103 to achieve different mixed color distribution effects.

[0023] like Fig. 9As shown, a replacement nozzle 106 is replaceably installed at the bottom of the tube body 103 of the present invention. The replacement nozzle 106 includes a replacement threaded head 106A, a replacement nozzle 106B and a replacement nozzle 106C. The replacement threaded head 106A is detachably mounted on the bottom of the tube body 103. A replacement nozzle 106B is provided at the bottom of the replacement threaded head 106A. A replacement nozzle 106C is provided at the bottom of the replacement nozzle 106B. The replacement threaded head 106A, the replacement nozzle 106B and the replacement nozzle 106C are internally connected. The replacement nozzle 106 is connected to the above-mentioned detachable nozzle 106. 04 The principles are the same, so they will not be elaborated in detail, but the main point is that the structure of the replacement nozzle 106C is different from that of the nozzle 104C. In this embodiment, the replacement nozzle 106C is a disc structure. Through the disc structure design, when the mixed A material, B material and additives are sprayed out, they will hit the disc structure at high speed, so that the mixture is broken into small particles, thereby achieving an atomization effect. It should be noted that, according to actual conditions, a discharge port can be set through the bottom of the tube body 103, and then other types of nozzles can be detachably installed on the discharge port, which can achieve the same effect.

[0024] like Figure 3 As shown, the mounting structure 9 of the present invention includes a connecting plate 91, which is fixedly mounted on the front end of the Z-axis rail 8, and a mounting plate 92 is provided at the front end of the connecting plate 91, and a docking plate 93 is provided at the front end of the mounting plate 92. The connecting plate 91, the mounting plate 92 and the docking plate 93 are all used for installation and connection. A clamping ring 94 is embedded at the top of the docking plate 93, and a pipe body 103 is embedded and installed in the clamping ring 94. A clamping head 95 is installed in cooperation with the clamping ring 94. One end of the clamping head 95 passes through the outer side of the docking plate 93 and is connected with the clamping ring 94. A threaded push rod is provided on the inner side of the clamping head 95, and a threaded hole is penetrated on the outer side of the docking plate 93. When the pipe body 103 is placed in the clamping ring 94, the clamping head 95 is rotated clockwise, and the threaded push rod will be screwed into the threaded hole penetrated on the outer side of the docking plate 93, and cooperate with the clamping ring 94 to push against the pipe body 103, thereby achieving a clamping and fixing effect. In this embodiment, two docking plates 93 are provided and symmetrically arranged at the front end of the mounting plate 92. Both docking plates 93 are provided with a clamping ring 94 and a clamping head 95. Two mixing injection structures can be installed to realize the spraying of a variety of different mixed materials and increase diversity.

[0025] like Fig.10 As shown, a method for making a mixed color sole, the method specifically comprises the following steps: Step S1: Material preparation: prepare material A, material B and additives, and bake material A. It should be noted that the additives are a mixture of catalyst, hardener, defoamer, wear-resistant oil, anti-yellowing agent and color paste. This is a prior art and will not be described in detail. Among them, material A is baked to a temperature of 50°C-80°C for 8H-12H. This step is to heat material A, reduce the moisture in material A, and activate the components inside it so that it can be better mixed with material B in the subsequent steps; Among them, material A is a polyester polyol mixture, and material B is an isocyanate, and the ratio of the two is 100:40-70. Polyester polyol mixture refers to a mixture composed of a variety of polyester polyols. These polyester polyols are usually prepared by condensation reaction or transesterification reaction of dibasic acid and polyol. Material B isocyanate is an intermediate, which can better mix material A and material B together; Step S2: External equipment: Adjust the number of mixing nozzle structures 10 according to the sum of material A and material B, and the adjustment number is 2:1. When material A is mixed with material B and an additive, one more mixing nozzle structure 10 is needed, so that a mixture of material A, material B and additives of various colors can be presented on the mold 4, thereby increasing the diversity of color mixing. An air gun is externally connected to the mixing nozzle structure 10. After the step of spraying the mixture is completed, the color mixing nozzle structure 10 starts the air gun to blow the mixture, so that the mixture presents a specified texture pattern in the mold 4, and the mixture sprayed on the mold 4 is blown out with a texture to increase the aesthetics. The barrel is connected to the feed port of the mixing nozzle structure 10 through a pump. The mixing nozzle structure 10 is externally connected to a pump and an air gun, wherein one end of the pump is connected to a barrel containing material A, material B and additives, and the other end is connected to the mixing nozzle structure 10. The mixing nozzle structure 10 is installed on the Z-axis track through the installation structure 9. Step S3: Color adjustment: For each color, color adjustment operations are performed on material A and material B respectively to ensure that the color meets the design requirements. This step is used to adjust different color mixing requirements; Step S4: Loading: The A material and B material with adjusted colors are loaded into the material barrels respectively, and the additives are loaded into the barrels of the A material and the B material. The A material is a common color and is loaded into the common barrel, and the B material is a mixed color, and each different color of the B material is loaded into a different barrel; Step S5: Positioning: Place the mold 4 into the machine 1 and position it. The purpose of positioning is to ensure the accuracy of the next step when the equipment will sequentially inject the mixed A material, B material and additives into the mold 4 according to the pattern setting path and the air gun performs the blowing operation; Step S6: Injection: Start the equipment, and the equipment will inject the mixture formed by mixing material A, material B and additives into the mold in sequence according to the pattern setting path. While injecting, material A, additives and material B will be mixed in the tube body 103 to form a mixture, and the mixing time is strictly controlled. By operating the control panel 2, the control panel 2 will control the X-axis track 7 on the horizontal plate 6, the Y-axis track 3 on the machine table 1 and the Z-axis track 8 on the X-axis track 7 through a pre-set program, so that the mixing nozzle structure 10 can be moved to a suitable position, and the material A, material B and additives are extracted from the barrel by a pump, and mixed in the mixing nozzle structure 10, wherein the mixing time of material A, additives and material B should not be greater than 25 / S; to prevent the mixing time from being too long and causing the material A, material B and additives to solidify, and then the mixing nozzle structure 10 sprays the mixture on the mold 4, and the pillar 5 is used for installation and connection; The color mixing nozzle structure 10 includes a docking head 101, which is used for an external pump. When working, material A, material B and additives are sprayed into the nozzle cover 102 and the tube body 103 through the docking head 101, and the stirring screw 105 arranged inside the tube body 103 is driven to rotate. The rotation of the stirring screw 105 can further stir and mix material A, material B and additives to form a mixture, and then the mixture is sprayed out through the detachable nozzle 104. It should be noted that after the detachable nozzle 104 sprays the mixture each time, in the process of completing the above work, the color mixing nozzle structure 10 will continuously change the spraying position through the X-axis track 7, the Y-axis track 3 and the Z-axis track 8; like Fig.11 As shown, when it is necessary to spray a mixture of two or more A materials and B materials and additives, two or more color mixing nozzle structures 10 are prepared in advance. For the convenience of distinction, the barrels for loading B materials of different colors are divided into B1 barrels and B2 barrels, and the barrels for loading A materials are called common barrels. The pumps are divided into No. 1 pumps and No. 2 pumps. The color mixing nozzle structure 10 is divided into No. 1 color mixing nozzle and No. 2 color mixing nozzle. The No. 1 color mixing nozzle structure is externally connected to the No. 1 pump and is connected to the output end of the No. 1 pump. Two feeding pipes are provided at the input end of the No. 1 pump, one of which is connected to the No. 1 pump. The second color mixing nozzle structure is externally connected to the second pump machine, and is connected to the output end of the second pump machine. The input end of the second pump machine is also provided with two feeding pipes, one of which is connected to the common barrel, and the other is connected to the barrel with B2. When this step is reached, a mixture of two kinds of A materials and B materials and additives can be sprayed. When it is necessary to spray a mixture of more than two kinds of A materials and B materials and additives, the above process can be repeated to complete it, so it will not be repeated; The detachable nozzle 104 includes a threaded head 104A. When working, the mixture will be pumped from the tube body 103 into the threaded head 104A, then flow into the nozzle 104B, and then the mixture will be sprayed out through the nozzle 104C. By changing the shape or structure of the nozzle 104C, the state of the mixture sprayed from the nozzle 104C will be different. For example, a single through hole is set at the bottom, and the mixture will be sprayed out along the through hole in a straight line; different mixed color soles can be customized according to different requirements of customers. The threaded head 104A of the detachable nozzle 104 is threadedly connected with the installation thread 103A at the bottom of the tube body 103. The threaded matching has the advantage of easy disassembly and assembly, which is convenient for the staff to replace different nozzles at the bottom of the tube body 103 to achieve different mixed color distribution effects; Among them, a replacement nozzle 106 can be installed at the bottom of the tube body 103. The replacement nozzle 106 has the same principle as the above-mentioned detachable nozzle 104. In this embodiment, the structure of the replacement nozzle 106C is different from that of the nozzle 104C. In this embodiment, the replacement nozzle 106C is a disc structure. Through the disc structure design, when the mixed material is in a state, it will hit the disc structure at high speed, and the mixed material will be broken into small particles, thereby achieving an atomization effect; It should be noted that after each process of the detachable nozzle 104 and the replaceable nozzle 106 is completed, the outlets thereof need to be cleaned to prevent blockage.

[0026] The mounting structure 9 includes a connecting plate 91. The connecting plate 91, the mounting plate 92 and the docking plate 93 are all used for installation and connection. When the tube body 103 needs to be fixed, the tube body 103 is placed in the clamping ring 94, and the clamping head 95 is rotated clockwise. The threaded rod will be screwed into the threaded hole provided on the outside of the docking plate 93, and cooperate with the clamping ring 94 to press against the tube body 103, thereby achieving a clamping and fixing effect.

[0027] Step S7: Step S7: Blowing treatment: After completing step S6, the air gun will follow the pattern setting path to blow the mixed material on the mold 4 to make it present the specified texture pattern; Step S8: removing bubbles: using a vacuum suction method to remove bubbles in the mixture in the mold cavity; removing bubbles can prevent cavities from appearing inside and on the surface of the mixture after aging, thereby improving the appearance, and removing bubbles can improve the density of the mixture and increase practical performance. It should be noted that the vacuum pump used in this step is a prior art that has already appeared on the market, and those skilled in the art can clearly understand its working principle and implementation method, so it will not be described in detail; The vacuuming time is 15S - 50S. If the time is too short, the bubbles in the mixture cannot be completely removed. If the time is too long, the mixing degree of the mixture will be destroyed, causing the two to be separated, increasing the scrap rate, and increasing the process time, which is not conducive to economic benefits. Step S9: hot pressing: hot pressing the mixture formed by material A, material B and the auxiliary agent to mature it and promote the full solidification of the mixture; this step is to transform the mixture from liquid to solid finished product; Among them, the hot pressing pressure is 400kgf-200kgf. If the hot pressing pressure is too small, the mixture will not be fully cured and cannot be formed. If the pressure is too large, it will destroy its formation and structure after curing, greatly increasing the scrap rate. The time is 3Min-8Min. If the hot pressing time is too long, if the hot pressing time is too short, the mixture will not be able to cure. If the hot pressing time is too long, it will destroy the cured finished product, causing its surface to be burnt or warped. The temperature is 60℃-120℃.
