Description

Technical Field

[0001] This invention relates to the field of shoe toe technology, specifically to lightweight basalt shoe toes. Background Technology

[0002] Toe caps are located at the top of shoes and serve to protect the toes. They are widely used in fields such as work shoes and military boots.

[0003] Traditional shoe toe caps are made of steel, which is simple to process and has been widely used in the market. However, as people’s requirements for wearing comfort continue to increase, traditional steel shoe toe caps can no longer meet the needs. They are heavy, which makes the whole shoe heavy, inconvenient for the wearer to move around, and causes foot fatigue.

[0004] Currently, to reduce the weight of shoe toe caps, most manufacturers use fiberglass as a component in the production of shoe toe caps. While this can significantly reduce the weight of the shoe toe cap while ensuring the required impact resistance, the use of fiberglass reduces the high-temperature resistance of the shoe toe cap, which can lead to flammability and lower the safety of using the shoe toe cap.

[0005] In summary, there is a current need for a lightweight shoe toe cap that balances strength and safety. Summary of the Invention

[0056] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, 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.

[0057] Example 1

[0058] To address the technical problems in the background art, a method for preparing lightweight basalt shoe toe caps is provided, comprising the following steps:

[0059] S1. Pre-impregnation processing:

[0060] S1.1 Add vinyl resin, magnesium oxide, and zinc stearate to the preparation tank and stir for 5 minutes to obtain the main slurry;

[0061] S1.2. The main slurry, basalt fiber cloth, PE film and polyester cloth are combined together in the composite machine to form prepreg 1, and then wound onto a roll.

[0062] S1.3 Transfer the roll to the baking rack;

[0063] S2, ripening:

[0064] The baking rack containing prepreg 1 is sent into the drying room, where the baking temperature is 38℃ and the baking time is 13h.

[0065] Prepreg 1 is converted into rolled material through high-temperature setting;

[0066] S3, Lamination:

[0067] S3.1 Pull out the baking rack after the curing process;

[0068] S3.2 Quickly coat the outer wall of the formed roll material with a film to obtain a film-coated formed roll material;

[0069] S3.3, Allow the film-formed roll material to cool statically;

[0070] S4. Cutting:

[0071] Remove the outer film from the film-formed roll material;

[0072] The roll containing the formed material is transferred from the baking rack to the slitting machine;

[0073] The formed roll material is continuously fed into the slitting machine, and the shoe toe mold inside the slitting machine punches out the shoe toe shape piece;

[0074] Workers stacked the toe pieces to form the toe block of the shoe bag;

[0075] S5, pressing and shaping;

[0076] The shoe toe block is placed in a pressing machine and hot-pressed to obtain a lightweight basalt shoe toe.

[0077] The above method can produce high-strength basalt steel toe caps, which can greatly reduce the overall weight of the toe cap while ensuring impact resistance.

[0078] By introducing basalt fiber material to replace fiberglass cloth, not only is the flame retardant effect of the shoe toe cap improved, but the risk of inhaling fiberglass debris generated during the processing of fiberglass cloth is also reduced, thus improving the safety of steel toe cap production and processing.

[0079] The introduction of a laminating machine to laminate prepreg 1 can effectively eliminate internal air in the main slurry and promote the fluidity of the main slurry, thereby improving the stability and efficiency of prepreg lamination.

[0080] In this embodiment, the weight percentages of the polyester fabric, basalt fiber fabric, vinyl ester resin, magnesium oxide, and zinc stearate are 35%, 40%, 20%, 3%, and 2%, respectively.

[0081] In this embodiment, the prepreg 1 includes a PE film 11 and a polyester fabric layer 12. The PE film 11 has two layers. The top surface of the lower PE film 11 is laminated with a polyester fabric layer 12, and the bottom surface of the upper PE film 11 is laminated with a basalt fiber fabric layer 14. The main slurry 13 is uniformly filled between the polyester fabric layer 12 and the basalt fiber fabric layer 14.

[0082] Example 2

[0083] like Figures 3-11 As shown, based on the above embodiments, this embodiment further provides the following:

[0084] To ensure stable lamination of prepreg 1, the following solution is proposed:

[0085] The composite machine includes a machine tool 2. The top of the machine tool 2 has a groove structure. Inside the groove of the machine tool 2, a first conveying roller 21, a second conveying roller 22, a third conveying roller 23, a fourth conveying roller 24, a fifth conveying roller 25, a sixth conveying roller 27, and a seventh conveying roller 28 are rotatably connected in sequence. A negative suction pump 8 is provided between the sixth conveying roller 27 and the seventh conveying roller 28. A first take-up drum 9a, a second take-up drum 9b, and a third take-up drum 9c are arranged in sequence on the top surface of the machine tool 2.

[0086] The first take-up roll 9a is wound with polyester fabric and is combined with the second conveyor roller 22 to form a composite polyester fabric layer 12. The second take-up roll 9b is wound with basalt fiber fabric and is combined with the sixth conveyor roller 27 to form a composite basalt fiber fabric layer 14. The third take-up roll 9c is wound with PE film 11 and is combined with the seventh conveyor roller 28 to form a composite PE film 11.

[0087] Two support plates 54 are fixed on the top surface of the machine tool 2. A material box 5 is fixed between the two support plates 54. A pneumatic pump 6 is connected through the top surface of the material box 5. A feeding assembly 4 is connected through the side wall of the material box 5. Two sets of feeding assemblies 4 are mirrored about the vertical center line of the material box 5. A feeding assembly 7 is set inside the material box 5. A discharge assembly 51 is fixed inside the material box 5. The material box 5 is divided into a collection chamber 52 and two feeding chambers 53 by the discharge assembly 51. The feeding assembly 4 and the feeding chambers 53 are connected through the material box 5. The feeding assembly 7 is installed through the collection chamber 52 and the feeding chambers 53. The discharge assembly 51 is installed through the bottom of the material box 5. Vibration stirring assemblies 3 are connected to both sides of the discharge assembly 51. The vibration stirring assemblies 3 are connected through the outside of the material box 5 and are engaged with the feeding assembly 4.

[0088] The prepreg 1 is laminated by a laminating machine. During the lamination process, the main slurry 13 is introduced into the material box 5 through the feeding component 4. Then, the main slurry 13 is introduced upward from the two feeding chambers 53 into the collecting chamber 52 through the feeding component 7. Under the vibration of the vibrating mixing component 3, it is concentrated and extruded onto the polyester fabric through the discharge component 51. This eliminates the air inside the main slurry 13, so that the main slurry 13 can be evenly extruded onto the polyester fabric to ensure the production quality of shoe and bag toes.

[0089] After the basalt fiber cloth is laminated onto the main slurry 13, the negative pressure suction of the negative suction pump 8 on the basalt fiber cloth draws part of the main slurry 13 into the gaps of the basalt fiber cloth, which improves the tightness of the composite of the basalt fiber cloth and the main slurry 13, thereby improving the structural strength of the prepreg 1 composite.

[0090] In this embodiment, a hot air blower 26 is embedded in the bottom surface of the groove of the machine tool 2, a fifth conveying roller 25 is disposed on the top of the hot air blower 26, the bottom end of the discharge assembly 51 is disposed directly above the fifth conveying roller 25, and the third conveying roller 23 and the fourth conveying roller 24 are respectively disposed on both sides of the fifth conveying roller 25. The third conveying roller 23, the fourth conveying roller 24 and the fifth conveying roller 25 cooperate to convexly convey the polyester fabric layer 12, so that the discharge assembly 51 can fully extrude and distribute the main slurry 13 on the polyester fabric layer 12.

[0091] By conveying the polyester fabric layer 12 in a raised position, the gaps in the polyester fabric can be increased, allowing the main slurry 13 to be fully bonded to the polyester fabric layer 12 when it is extruded and laminated, thereby further improving the structural strength of the prepreg 1 composite.

[0092] During the process of introducing and extruding the main slurry 13, the poor fluidity of the main slurry 13 itself reduces the extrusion efficiency. To solve the above problem, the following solution is proposed:

[0093] In this embodiment, the feeding assembly 4 includes a feeding pipe 41, a guide box 42, a first heating plate 43, a first motor 44, a second rotating shaft 45, and a stirring wheel 46. One side of the guide box 42 is fixed to the side wall of the material box 5, and the guide box 42 is connected to the inside of the material box 5. The other side of the guide box 42 is connected to the feeding pipe 41. The top and bottom surfaces of the guide box 42 are provided with the first heating plate 43. The top surface of the guide box 42 is provided with the first motor 44. The bottom end of the first motor 44 is connected to the second rotating shaft 45. The stirring wheel 46 is sleeved on the outer wall of the second rotating shaft 45. The side wall of the stirring wheel 46 is fixed with a pusher block 461. Four pusher blocks 461 are arranged in a cross shape.

[0094] The main slurry 13 is initially heated by the two upper and lower first heating plates 43, which improves the fluidity of the main slurry 13. Under the rotational pushing action of the stirring wheel 46, the main slurry 13 is promoted to enter the material box 5.

[0095] In this embodiment, the feeding component 4 further includes a cam 47 and a second helical gear 48. The bottom end of the second rotating shaft 45 passes through the bottom of the guide box 42 and is connected to the second helical gear 48. One side of the second helical gear 48 is meshed with the vibration stirring component 3. The cam 47 is sleeved and fixed on the outer wall of the second rotating shaft 45. One side of the cam 47 is fitted with the vibration stirring component 3.

[0096] While driving the stirring wheel 46 to push the main slurry 13 into the material box 5, the cam 47 can also reciprocate to push the vibration stirring component 3, and the second helical gear 48 drives the vibration stirring component 3 to stir, which further improves the fluidity of the main slurry 13 when it is introduced and discharged from the material box 5.

[0097] In this embodiment, the vibrating stirring assembly 3 includes a first helical gear 31, a push plate 32, a spring 33, a sealing ring 34, a sleeve 35, a flap 36, a first rotating shaft 37, and a key 38. One end of the first rotating shaft 37 is rotatably connected to the discharge assembly 51, and the other end is fixed with the first helical gear 31. The first helical gear 31 is meshed with the second helical gear 48. The sleeve 35 is sleeved on the outer wall of the first rotating shaft 37. The push plate 32 is sleeved and fixed on the outer wall of one end of the sleeve 35, and the flap 36 is fixed on the outer wall of the other end. The key 38 is embedded in the outer wall of the first rotating shaft 37 and inserted into the inside of the sleeve 35. The sleeve 35 is inserted through the inside of the material box 5. The sealing ring 34 is sleeved on the outer wall of the sleeve 35 and fixed to the side wall of the material box 5. The spring 33 is sleeved on the outer wall of the sleeve 35 and is disposed between the sealing ring 34 and the push plate 32.

[0098] In this embodiment, the discharge assembly 51 includes a partition 511, a second heating plate 512, a feeding box 513, and an extrusion head 514. The partition 511 is fixed to the inner wall of the material box 5. The feeding box 513 is connected to the bottom surface of the partition 511. A through groove 5112 is opened inside the partition 511. The through groove 5112 and the top surface of the feeding box 513 are connected through the groove. The bottom end of the feeding box 513 is inserted through the bottom of the material box 5. Fixing blocks 5131 are provided on both sides of the side wall of the feeding box 513. One end of the first rotating shaft 37 is rotatably connected to the inside of the fixing block 5131. The extrusion head 514 is inserted into the bottom end of the feeding box 513. Two second heating plates 512 are vertically connected to the bottom surface of the partition 511. The feeding assembly 7 is connected through the inside of the partition 511.

[0099] During the process of exporting the main slurry 13, because the collecting chamber 52 and the feeding chamber 53 remain connected, some of the main slurry 13 will flow back, and the air pressure in the larger chamber needs to be controlled, both of which will reduce the extrusion efficiency of the main slurry 13. To solve this problem, the following solution is proposed:

[0100] The feeding assembly 7 includes a pneumatic rod 71, a lifting plate 72, and a conveying group. The pneumatic rod 71 is set on the top surface of the material box 5. The bottom end of the pneumatic rod 71 is connected to the lifting plate 72. A guide rod 55 is fixed on the top surface inside the material box 5. The guide rod 55 is slidably inserted into the inside of the lifting plate 72. The bottom of the lifting plate 72 is rotatably connected to the conveying group. The conveying group is arranged in a rectangular distribution with four groups. The partition plate 511 has four through holes 5111 arranged in a rectangular distribution inside. The conveying group is connected to the material collection chamber 52 and the feeding chamber 53 through the through holes 5111.

[0101] The conveying assembly includes a rotating rod 73, a spiral blade 74, a positioning block 75, a sealing plate 76, a second motor 77, and a shaft 78. The top of the rotating rod 73 is rotatably connected to the inside of the lifting plate 72. The spiral blade 74 is fixed to the outer wall of the rotating rod 73. A retaining ring 731 is sleeved and fixed to the outer wall of the bottom end of the rotating rod 73. The sealing plate 76 is sleeved on the outer wall of the rotating rod 73. The bottom surface of the sealing plate 76 is attached to the top surface of the retaining ring 731. The positioning block 75 is fixed to the top surface of the sealing plate 76. The second motor 77 is located on the bottom surface of the material box 5. The top of the rotating motor 77 passes through the inside of the material box 5 and is connected to the shaft 78. The shaft 78 is slidably inserted into the bottom end of the rotating rod 73. A slot 732 is opened inside the bottom end of the rotating rod 73. A limit strip 781 is fixed to the side wall of the shaft 78. The limit strip 781 is inserted into the slot 732. The sealing plate 76 is pulled up by a pneumatic rod 71 and is attached to and sealed between the side wall of the second heating plate 512 and the unloading box 513.

[0102] The rotating spiral blade 74 drives the main slurry 13 into the collection chamber 52. When the main slurry 13 in the collection chamber 52 is squeezed into the feed box 513, the sealing plate 76 is pulled up to cooperate with the second heating plate 512 to seal the bottom of the through hole 5111 and reduce the volume of the chamber that needs to be controlled by the air pressure, thereby improving the extrusion efficiency of the main slurry 13.

[0103] When this embodiment is implemented in Embodiment 1,

[0104] according to Figures 3-11First, the mixed main slurry 13 is introduced into the material box 5. The main slurry 13 is introduced into the guide box 42 through the feed pipe 41. The first heating plate 43 heats the main slurry 13. Then, the first motor 44 is started to drive the stirring wheel 46 to rotate. The pusher block 461 pushes the main slurry 13 into the feed chamber 53 of the material box 5. The second heating plate 512 further heats the main slurry 13 to improve its fluidity. At the same time, the second rotating shaft 45 drives the second helical gear 48 and the cam 47 to rotate. The second helical gear 48 drives the first helical gear 31 to rotate. The first rotating shaft 37 drives the sleeve 35 to rotate, so that the flip plate 36 flips to stir the main slurry 13 in the feed chamber 53. The cam 47 rotates and repeatedly pushes the pusher plate 32, pushing the sleeve 35 to collide with the fixed block 5131, so that the feed box 513 vibrates and compacts the main slurry 13 in the feed chamber 53 to eliminate the air inside the main slurry 13.

[0105] Then, the second motor 77 is started to rotate the rotating rod 73. The spiral blade 74 drives the main slurry 13 to spiral upward, enter the collection chamber 52 through the through hole 5111, and flow downward into the discharge box. Under the vibration of the discharge box, the air inside the main slurry 13 inside the discharge box is further eliminated. After enough main slurry 13 to be compounded is introduced into the collection chamber 52, the pneumatic rod 71 is started to pull the lifting plate 72 upward. The lifting plate 72 drives the rotating rod 73 upward. The retaining ring 731 drives the sealing plate 76 to rise and cooperate with the second heating plate 512 and the side wall of the discharge box 513 to seal, so that the bottom of the through hole 5111 is sealed, ready to extrude the main slurry 13.

[0106] Next, the prepreg 1 is laminated using a laminating machine. First, a layer of PE film 11 is conveyed on the machine tool 2 by the first conveying roller 21. Then, the polyester fabric on the first take-up roll 9a is turned and conveyed by the second conveying roller 22 and laminated onto the PE film 11. Under the combined conveying of the third conveying roller 23, the fourth conveying roller 24 and the fifth conveying roller 25, the laminated PE film 11 and polyester fabric are conveyed upwards. The hot air blower 26 heats the fifth conveying roller 25 to preheat the polyester fabric passing through it. Then, the air pressure pump 6 is started to pressurize the inside of the collection chamber 52. The main slurry 13 inside the feeding box 513 is evenly extruded onto the raised polyester fabric through the extrusion head 514 and filled into the gaps in the polyester fabric, so that the main slurry 13 and the polyester fabric are fully laminated.

[0107] Then, after the main sizing agent 13 is laminated onto the polyester fabric layer 12, the basalt fiber fabric on the second take-up roll 9b is turned and conveyed by the sixth conveying roller 27 and laminated onto the main sizing agent 13. Then, when passing through the negative suction pump 8, a negative pressure is generated inside the basalt fiber fabric, so that part of the main sizing agent 13 is sucked into the pores of the basalt fiber fabric, fully laminating the basalt fiber fabric and the main sizing agent 13. Finally, the PE film 11 on the third take-up roll 9c is turned and conveyed by the seventh conveying roller 28 and laminated onto the basalt fiber fabric. After being rolled by the rolling roller 9, the lamination of the prepreg 1 is completed.
