Description

Technical Field

[0001] This invention relates to the field of shoe sole processing technology, specifically to a two-color shoe sole and its processing technology. Background Technology

[0002] In existing technologies, different functional sports shoes are produced to suit different sports characteristics. The soles of these shoes must be wear-resistant, have good elasticity, be waterproof, and be comfortable, lightweight, and soft. Currently, most of these soles are made of EVA material. Existing manufacturing methods mostly employ a one-step injection molding foaming process. The process involves: after EVA raw materials are mixed and granulated, molten EVA is injected into a molding die using an injection molding machine for cross-linking and foaming. The mold temperature is required to be between 160℃ and 175℃, the cross-linking and foaming time is approximately 420 to 520 seconds, and the compression ratio is approximately 6.5 kg / cm². After cross-linking and foaming, the mold is opened instantly, utilizing the foaming tension to expand the EVA to its maximum volume (approximately 1.85 to 2 times), forming a semi-finished product. The semi-finished product is removed from the mold at a temperature of approximately 95℃ to 100℃, and then cooled at different stages until it reaches room temperature, allowing the semi-finished sole to solidify under free shrinkage. After measurement and rejection of defective products, the finished sole is obtained.

[0003] For comfort, shoes are usually made larger than the user's feet. When the user's feet sweat, and when the user exercises, the user's feet will slip on the upper surface of the sole, which may cause the user's feet to tear the shoe upper. Summary of the Invention

[0004] This invention provides a two-tone sole that has the beneficial effect of preventing slippage.

[0006] The accommodating space is provided with a plurality of airbags, and a first arc-shaped spring is installed inside the plurality of airbags. The plurality of airbags are sequentially installed on the lower end face of the aluminum cover. Inside the aluminum cover and near the first protrusion and the second protrusion, a ventilation sleeve and a second ventilation groove are also installed. One end of the ventilation sleeve is connected to the interior of the first protrusion, and the other end of the ventilation sleeve is connected to one of the first arc-shaped springs.

[0008] As an alternative embodiment of the two-color sole of the present invention, an air supply strip is connected between several air bladders, and both ends of each air supply strip are connected to a first arc-shaped spring piece.

[0009] As an optional embodiment of the two-color sole of the present invention, wherein: the inner wall of the ventilation sleeve is symmetrically equipped with a first baffle and a second baffle, the two ends of the first baffle and the second baffle abut against each other and the first baffle and the second baffle are used to seal the ventilation sleeve.

[0010] Both the first baffle and the second baffle have through holes at one end, and the air at the first protrusion is used to flow through the through holes into the interior of the first arc-shaped spring.

[0011] As an alternative embodiment of the two-color sole of the present invention, a baffle is further installed on the upper end of the upper rubber plate, and the baffle is operable to abut against one end of the first protrusion.

[0012] The upper end face of the upper layer adhesive sheet is provided with a slope.

[0013] As an optional embodiment of the two-color sole of the present invention, wherein: the upper rubber plate is provided with an adjustment groove inside, and the baffle is slidably connected to the adjustment groove;

[0014] A spring rope is installed at one end of the first baffle, and one end of the spring rope is connected to the baffle.

[0015] As an optional embodiment of the two-color sole of the present invention, a sealing device is also installed on the inner wall of the ventilation sleeve near the second baffle, the sealing device is connected to the second baffle, and a second ventilation groove is also installed inside the upper rubber plate and is connected to the sealing device.

[0016] As an optional solution for the two-color sole of the present invention, the sealing device includes a sealing groove disposed on the inner wall of the ventilation sleeve, a sealing plug disposed on the inner wall of the sealing groove, a second arc-shaped spring piece installed on the upper end of the second baffle, and the sealing plug and the second baffle being connected by the second arc-shaped spring piece.

[0017] The upper layer of the adhesive sheet also has a first ventilation groove that communicates with the second ventilation groove. A sliding column is slidably connected inside the first ventilation groove. A limiting plate is installed at the upper end of the sliding column. The inner wall of the upper layer of the adhesive sheet also has a limiting groove. The limiting plate is slidably connected to the inner wall of the limiting groove.

[0018] As an alternative embodiment of the two-color sole of the present invention, each of the semi-cylinders is provided with a groove, and a protrusion is installed on one side of each airbag, the protrusion being used to snap into the inside of the groove;

[0019] Friction strips are provided on the outer surfaces of both the first and second protrusions.

[0020] This invention also provides a processing technology for two-tone shoe soles.

[0021] S1. Take foamed granules and heat them to 80-100℃ to make a molten liquid base material. Then, put the liquid base material into the base mold to obtain the bottom layer adhesive board.

[0022] S2. Open the mold and place the aluminum cover on the upper surface of the bottom rubber plate, then pour the liquid base material back into the upper mold.

[0023] S3. The material obtained in S2 is vulcanized at 150-175℃, cooled and shaped to form the shoe sole;

[0024] S4. The sole obtained in S3 is further processed to create friction strips on its surface, thus completing the processing.

[0025] The present invention has the following beneficial effects:

[0026] 1. The two-tone sole supports the lower part of the toes and the sole of the foot respectively through the first and second protrusions. The air bladder will transfer the internal air to the first and second protrusions, making the first and second protrusions expand more, thus allowing the first and second protrusions to better support the user's feet.

[0027] 2. The two-tone sole, by setting the first and second baffles in a figure-eight shape, allows the returning air to be compressed onto the first and second baffles, causing the first and second baffles to close the opening. As a result, the air can only slowly return from the through hole, thus ensuring that the first protrusion can expand for a longer period of time to support the lower part of the user's toes, further preventing the user's foot from sliding forward and causing danger.

[0028] 3. The two-tone sole transmits air through the first ventilation channel to the second ventilation channel, which in turn transmits air to the second protrusion, causing the second protrusion to expand and support the user's arch, thereby preventing the user's foot from slipping.

[0035] 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.

[0036] Example 1

[0037] Please see Figure 1-4 It includes a bottom adhesive plate 1, an aluminum cover 2 installed on the upper end of the bottom adhesive plate 1, an accommodating space between the aluminum cover 2 and the bottom adhesive plate 1, an upper adhesive plate 3 installed on the upper end of the aluminum cover 2, and a first protrusion 10 and a second protrusion 11 installed sequentially on the upper end of the upper adhesive plate 3, with the first protrusion 10 and the second protrusion 11 respectively close to both ends of the upper adhesive plate 3.

[0038] The interior of the accommodating space is provided with several airbags 7, and the interior of the airbags 7 is equipped with first arc-shaped spring pieces 6. The airbags 7 are sequentially installed on the lower end face of the aluminum cover 2. Inside the aluminum cover 2, near the position of the first protrusion 10 and the second protrusion 11, there is also a ventilation sleeve 14 and a second ventilation groove 25. One end of the ventilation sleeve 14 is connected to the interior of the first protrusion 10, and the other end of the ventilation sleeve 14 is connected to one of the first arc-shaped spring pieces 6.

[0039] For comfort, shoes are usually larger than the user's feet. When the user's feet sweat, and when the user exercises, the user's feet will slip on the upper surface of the sole, which may cause the user's feet to tear the shoe upper. Therefore, this device has a first protrusion 10 and a second protrusion 11 on the upper surface of the upper rubber plate 3. The first protrusion 10 supports the lower part of the toes, and the second protrusion 11 supports the sole of the foot to fix the foot.

[0040] For details, please refer to Figure 1 The user places their foot on the upper surface of the upper rubber plate 3, where the lower part of the toes and the sole of the foot are supported by the first protrusion 10 and the second protrusion 11 respectively. Several airbags 7 are installed on the lower surface of the aluminum cover 2. When the user steps on the upper rubber plate 3, the upper rubber plate 3 will compress the airbags 7 and the first arc-shaped spring 6, so that the airbags 7 will transmit the air inside to the first protrusion 10 and the second protrusion 11, making the first protrusion 10 and the second protrusion 11 more inflated, thereby allowing the first protrusion 10 and the second protrusion 11 to better support the user's foot.

[0041] It should be noted that, see reference Figure 2 When the user steps on the upper rubber plate 3, the airbag 7 will be compressed. When the user stops stepping on the upper rubber plate 3, the airbag 7 will rebound and the upper rubber plate 3 will return to its original position. At the same time, the first arc-shaped spring 6 will also draw back the ejected air.

[0042] Example 2

[0043] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 1-4 The interior of the accommodating space is also provided with several semi-cylinders 5, which are installed on the upper surface of the bottom rubber plate 1. There is a gap between every two semi-cylinders 5, and the lower surface of several airbags 7 is fastened to the gap.

[0044] Several airbags 7 are connected by air supply strips 13, and both ends of each air supply strip 13 are connected to the first arc-shaped spring piece 6.

[0045] Easy installation: When the aluminum cover 2 needs to be installed on the bottom rubber plate 1, the airbag 7 is first snapped into the gap between each pair of semi-cylinders 5, and then the protrusion 9 is snapped into the inside of the groove 8 to fix the aluminum cover 2. When the user's foot slides forward, in order to prevent the aluminum cover 2 and the bottom rubber plate 1 from detaching, the protrusion 9 is snapped into the inside of the groove 8 to increase the connection stability between the aluminum cover 2 and the bottom rubber plate 1.

[0046] Example 3

[0047] This embodiment is an improvement upon embodiment 2. For details, please refer to [link / reference]. Figure 1-4The inner wall of the ventilation sleeve 14 is symmetrically equipped with a first baffle 17 and a second baffle 18. The two ends of the first baffle 17 and the second baffle 18 abut against each other and the first baffle 17 and the second baffle 18 are used to seal the ventilation sleeve 14.

[0048] One end of the first baffle 17 and the second baffle 18 is provided with a through hole 19, and the air at the first protrusion 10 is used to flow through the through hole 19 to the interior of the first arc-shaped spring 6.

[0049] Fast in, slow out: See Figure 4 When air enters the ventilation sleeve 14 from inside the first arc-shaped spring 6, it compresses the first baffle 17 and the second baffle 18 to expand to both sides, creating a large opening in the first baffle 17 and the second baffle 18. This allows a large amount of air to enter the interior of the first protrusion 10, enabling the first protrusion 10 to effectively support the lower part of the user's toes. Subsequently, to prevent the incoming air from flowing back quickly, the first baffle 17 and the second baffle 18 are arranged in a figure-eight shape. This causes the flowing air to be compressed onto the first baffle 17 and the second baffle 18, closing the opening. As a result, the air can only slowly flow back from the through hole 19, ensuring that the first protrusion 10 can expand for a longer period of time to support the lower part of the user's toes, further preventing the user's foot from sliding forward and causing danger.

[0050] It should be noted that the opening size of the first baffle 17 and the second baffle 18 is larger than the opening size of the through hole 19.

[0051] Example 4

[0052] This embodiment is an improvement upon embodiment 3. For details, please refer to [link / reference]. Figure 1-4 A baffle 15 is also installed on the upper end of the upper layer of the adhesive sheet 3. The baffle 15 is operable to abut against one end of the first protrusion 10. An inclined surface 4 is provided on the upper end surface of the upper layer of the adhesive sheet 3.

[0053] The upper adhesive plate 3 has an adjustment groove 16 inside, and the baffle 15 is slidably connected to the adjustment groove 16.

[0054] A spring rope 20 is installed at one end of the first baffle 17, and one end of the spring rope 20 is connected to the baffle 15.

[0055] Support compression: According to Figure 4 As shown, when the user's toes step on the first protrusion 10, in order to prevent the first protrusion 10 from deforming too much and failing to support the lower end of the user's toes, a baffle 15 is provided on one side of the first protrusion 10. The baffle 15 supports one side of the first protrusion 10 and prevents the first protrusion 10 from deforming too much.

[0056] Furthermore, when the returning air compresses the first baffle 17 and the second baffle 18 to deform downwards, the first baffle 17 pulls the spring rope 20 to slide to the right, and the spring rope 20 pulls the baffle 15 to slide to the right, so that the baffle 15 will compress the first protrusion 10, thereby reducing the deformation range of the first protrusion 10, so that the first protrusion 10 can better support the lower end of the user's toes.

[0057] Example 5

[0058] This embodiment is an improvement upon embodiment 4. For details, please refer to [link / reference]. Figure 1-5 A sealing device is also installed on the inner wall of the ventilation sleeve 14 near the second baffle 18. The sealing device is connected to the second baffle 18. A second ventilation groove 25 is also installed inside the upper rubber plate 3 and is connected to the sealing device.

[0059] The sealing device includes a sealing groove 22 provided on the inner wall of the vent sleeve 14, a sealing plug 23 provided on the inner wall of the sealing groove 22, a second arc-shaped spring piece 21 installed on the upper end of the second baffle 18, and the sealing plug 23 and the second baffle 18 are connected through the second arc-shaped spring piece 21.

[0060] The upper layer of the adhesive sheet 3 is also provided with a first ventilation groove 24 that communicates with the second ventilation groove 25. A sliding column 26 is slidably connected inside the first ventilation groove 24. A limiting plate 28 is installed at the upper end of the sliding column 26. A limiting groove 27 is also provided on the inner wall of the upper layer of the adhesive sheet 3. The limiting plate 28 is slidably connected to the inner wall of the limiting groove 27.

[0061] Each semi-cylindrical 5 is provided with a groove 8, and each airbag 7 is provided with a protrusion 9 on one side, which is used to snap into the inside of the groove 8.

[0062] Friction strips 12 are provided on the outer surfaces of both the first protrusion 10 and the second protrusion 11.

[0063] First support the foot, then support the arch: When the user forcefully steps on the first protrusion 10, it means the user needs to exert force with their toes, thus requiring the air inside the first protrusion 10 to be expelled in time; otherwise, the first protrusion 10 may explode. Therefore, the device has a second arc-shaped spring piece 21 and a sliding post 26 inside the upper rubber plate 3. (See reference...) Figure 5When the user steps hard on the first protrusion 10, the air inside the first protrusion 10 will squeeze the first baffle 17 and the second baffle 18 downwards. As a result, the second baffle 18 will deform downwards, causing the second arc-shaped spring 21 to slide downwards. The second arc-shaped spring 21 will pull the sealing plug 23 and the sliding column 26 to slide to the left, exposing the first ventilation groove 24. This allows the air on the upper surface of the second baffle 18 to enter the first ventilation groove 24 and be transmitted to the second ventilation groove 25 through the first ventilation groove 24. The second ventilation groove 25 then transmits the air to the second protrusion 11, causing the second protrusion 11 to expand. The second protrusion 11 then supports the user's foot, thus preventing the user's foot from slipping.

[0064] Example 6

[0065] This invention also provides a processing technology for two-tone shoe soles.

[0066] S1. Take foamed granules and heat them to 80-100℃ to make a molten liquid base material. Then, put the liquid base material into the base mold to obtain the bottom layer adhesive board 1.

[0067] S2. Open the mold and place the aluminum cover 2 on the upper surface of the bottom rubber plate 1, then pour the liquid base material back into the upper mold.

[0068] S3. The material obtained in S2 is vulcanized at 150-175℃, cooled and shaped to form the shoe sole;

[0069] S4. The sole obtained in S3 is processed a second time to create friction strips 12 on its surface, thus completing the processing.
