Description

Technical Field

[0001] This invention relates to the field of shoe manufacturing technology, specifically to an auxiliary device for bonding the sole of casual shoes. Background Technology

[0002] Casual shoes are a very popular type of footwear, typically characterized by comfort, lightness, and style, making them suitable for everyday wear, especially for casual occasions. During the production of casual shoes, the sole and upper are bonded together using adhesives such as glue.

[0003] In the prior art, Chinese Patent Application No. CN201711400081.4 discloses a sole bonding device for odor-resistant sports shoes, including a main body, a glue baffle, and an adhesive tank. The main body has a wheel rod at its lower end and a working platform at its upper end. A blower is fixedly installed on the outer surface of the working platform. A lifting rod is provided on one side of a detachable positioning column assembly. A glue spray gun is provided at one end of the adhesive tube, and a pressure boosting pipe is provided on one side of the adhesive tank. A pressure boosting device is provided at one end of the pressure boosting pipe. With a blower, glue baffle, and detachable positioning columns, the device can quickly dry the adhesive inside the bonded sports shoe and prevent glue splattering during pressing. It also provides more stable positioning of the sports shoe, reducing the occurrence of bonding misalignment. It is suitable for various working conditions and offers better application prospects.

[0004] For example, in the prior art, Chinese patent application number CN202010695876.8 discloses a shoe sole bonding press for shoemaking, including: a machine housing, a bonding component, a drive component, a control console, and a foot switch. The machine housing includes an upper part, a connecting part, and a lower part, which together form an operating area with openings on three sides. The bonding component is located in the operating area. The drive component is used to drive the bonding component. The control console is located on the upper part and is used to control the bonding component and the drive component. The foot switch is located on the lower part and is used to start or stop the bonding component. The bonding component includes a horizontal bonding component and a vertical bonding component. The horizontal bonding component is used to bond the side of the shoe sole, and the vertical bonding component is used to apply vertical pressure to the shoe sole.

[0005] For example, in the prior art, Chinese patent application number CN202321656950.0 discloses a shoe sole bonding machine, including a frame, shoe material, and a worktable fixedly mounted on the frame. The frame is provided with a pressing component and an adhesive filling component. The pressing component includes a hydraulic cylinder fixedly mounted above the frame and a pressing plate fixedly mounted below the piston rod of the hydraulic cylinder. The adhesive filling component includes an adhesive filling frame fixedly mounted on the frame, a guide rod cylinder fixedly mounted inside the adhesive filling frame, and a moving plate. The moving plate is connected to the worktable through a moving component. The adhesive filling frame is located in front of the pressing plate. When the shoe material is in the adhesive filling state, the shoe material is in contact with the adhesive filling frame and the push plate of the guide rod cylinder. When the shoe material is in the pressing state, the shoe material is in contact with the moving plate.

[0006] Based on the above information, it can be seen that in existing technologies, pressure is generally applied to the glued sole and upper using a pressing mold to achieve the bonding purpose. However, in actual use, soles made of thermoplastic materials such as rubber, TPU, and EVA need to be heated during bonding to soften the materials and achieve a better bonding effect. After bonding, without cooling measures, the mold and shoe surface temperature are high, posing a certain danger to workers during operation, and the high temperature of the sole can easily cause deformation. Summary of the Invention

[0007] The purpose of this invention is to provide a casual shoe sole bonding auxiliary device to solve the problems of poor cooling effect and easy deformation of the sole mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a casual shoe sole bonding auxiliary device, comprising a horizontally placed operating platform, a control computer fixedly mounted on the upper surface of the operating platform, a bearing turntable rotatably mounted on the upper surface of the front end of the operating platform, two lower pressing molds fixedly mounted on the upper surface of the bearing turntable, and a heating coil fixedly mounted on the upper surface of the bearing turntable. The lower pressing molds have accommodating grooves inside, and an ejection mechanism is provided inside the accommodating grooves. An electrical control box is fixedly mounted on the upper surface of the operating platform, and a fixing plate is fixedly mounted on the front side of the electrical control box. A telescopic cylinder is fixedly mounted on the lower surface of the fixing plate, and an upper pressing mold is fixedly mounted at the lower end of the telescopic cylinder. A pressure injector is fixedly mounted on the upper surface of the upper pressing mold. A storage box is fixedly mounted in the middle of the upper surface of the bearing turntable, and the storage box contains a first storage tank and a second storage tank. The first storage tank stores coolant and has a stirring mechanism to accelerate cooling.

[0009] Preferably, a cooling pipe with a bent structure is fixedly installed inside the lower end of the pressing mold, and the front end of the cooling pipe is connected to the first storage tank inside the storage box through the first pump body.

[0010] Preferably, the agitation mechanism includes a connecting rod that is horizontally installed inside the storage tank, and the connecting rod and the storage tank form a through sliding structure, and a cooling plate is fixedly installed on the lower surface inside the first storage tank.

[0011] Preferably, a stirring plate is fixedly installed on the lower surface of the middle position of the connecting rod, and a first magnetic block is fixedly installed at the front end of the connecting rod, and a reset spring located outside the connecting rod is fixedly installed between the first magnetic block and the storage box.

[0012] Preferably, the positions of the first magnetic block and the second magnetic block correspond to each other, and the first magnetic block and the second magnetic block repel each other magnetically, and the second magnetic block is fixedly mounted on the upper surface of the mounting plate.

[0013] Preferably, the mounting plate is fixedly mounted on the upper surface of the operating platform, and a drive roller is rotatably mounted on the upper surface of the operating platform, with the side of the drive roller and the side of the bearing turntable pressed against each other.

[0014] Preferably, a horizontally arranged support plate is installed inside the receiving groove, and the support plate slides relative to the receiving groove, and an ejector spring is fixedly installed between the lower surface of the support plate and the bottom of the receiving groove.

[0015] Preferably, an atomizing nozzle is fixedly installed on the outer side of the lower pressing mold, and the position of the atomizing nozzle corresponds to the position of the receiving groove, and a connecting pipe is fixedly installed on the side of the atomizing nozzle.

[0016] Preferably, the connecting pipe is interconnected with the second storage tank via the second pump body, and the second storage tank contains adhesive remover.

[0017] Preferably, a stirring rod for stirring the adhesive remover is rotatably installed inside the second storage tank, and a friction roller is coaxially fixedly installed above the stirring rod, and the friction roller and the outer surface of the rear end of the connecting rod are in contact and rub against each other.

[0018] Compared with the prior art, the beneficial effects of the present invention are: the casual shoe sole bonding auxiliary device adopts a novel structural design, the specific details of which are as follows: 1. Place the soles and uppers to be bonded into the receiving groove inside the lower pressing mold. Then, drive the rollers to rotate the bearing turntable, which in turn rotates the lower pressing mold to the rear. Then, in conjunction with the telescopic cylinder and the upper pressing mold, the bonding purpose is achieved. During the pressing process, the mold is heated by the heating coil, and the pressurizer applies pressure to the inside of the mold to achieve a better bonding effect. Furthermore, after the bonding is completed, the first pump body is turned on, so that the first pump body delivers the coolant in the first storage tank to the cooling pipe for circulation, thereby using the cooling pipe to cool the lower pressing mold, so as to avoid the shoes from deforming when they are taken out due to prolonged high temperature. When the coolant flows back to the first storage tank, it is cooled by the internal cooling plate to ensure the effect of subsequent use. Furthermore, during the rotation of the turntable, the storage tank and the first magnetic block move. When the first magnetic block moves to the position corresponding to the second magnetic block, the magnetic repulsion between the first and second magnetic blocks pushes the connecting rod to move, causing the connecting rod to move the stirring plate inside the first storage tank (in conjunction with the return spring, the stirring plate moves back and forth), thereby achieving the purpose of stirring the coolant and improving the cooling speed of the coolant by the cooling plate.

[0019] 2. During the pressing process of the sole and upper, the support plate moves downward inside the receiving groove under pressure, causing the support plate to squeeze the ejector spring. After pressing, the restoring elasticity of the ejector spring is used to lift the support plate upward, thereby lifting the shoe that has been glued together, making it easy for staff to pick up. Furthermore, the second pump body is turned on to pressurize and spray the adhesive remover in the second storage tank through the connecting pipe from the atomizing nozzle, thereby spraying the adhesive remover onto the support plate. The adhesive remover removes any residual adhesive on the surface of the support plate. When the connecting rod moves, it uses friction to drive the friction roller to rotate, which in turn drives the stirring rod to rotate. The stirring rod agitates the adhesive remover, preventing it from settling if left for a long time. Attached Figure Description

[0022] 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.

[0023] Example 1: Please refer to Figures 1-4 and Figure 8 , Figure 9 To achieve the purpose of bonding the sole and upper in this embodiment, the following technical solution is provided, specifically: a horizontally placed operating platform 1, a control computer 2 fixedly mounted on the upper surface of the operating platform 1, a bearing turntable 3 rotatably mounted on the front upper surface of the operating platform 1, two pressing molds 4 fixedly mounted on the upper surface of the bearing turntable 3, and a heating coil 6 fixedly mounted on the upper surface of the bearing turntable 3; a receiving groove 5 is provided inside the pressing mold 4, and an ejection mechanism is provided inside the receiving groove 5; an electrical control box 7 is fixedly mounted on the upper surface of the operating platform 1, and a fixed... Plate 8, and a telescopic cylinder 9 is fixedly installed on the lower surface of plate 8. An upper pressing mold 10 is fixedly installed at the lower end of the telescopic cylinder 9. A pressure device 11 is fixedly installed on the upper surface of the upper pressing mold 10. A horizontally arranged support plate 23 is installed inside the receiving groove 5, and the support plate 23 slides relative to the receiving groove 5. An ejector spring 24 is fixedly installed between the lower surface of the support plate 23 and the bottom of the receiving groove 5. A mounting plate 21 is fixedly installed on the upper surface of the operating platform 1, and a drive roller 22 is rotatably installed on the upper surface of the operating platform 1. The side of the drive roller 22 is pressed against the side of the bearing turntable 3.

[0024] When using the device, first place the sole and upper to be bonded into the receiving groove 5 inside the lower pressing mold 4. Then, the motor inside the operating platform 1 drives the drive roller 22 to rotate, and the friction of the drive roller 22 drives the bearing turntable 3 to rotate, rotating the lower pressing mold 4 containing the shoes to the rear. Then, the telescopic cylinder 9 is activated, causing the telescopic cylinder 9 to push the upper pressing mold 10 downward, finally bonding the upper pressing mold 10 with the lower pressing mold 4. Under pressure, the sole and upper coated with glue are bonded together. During this process, the heating coil 6 is turned on to heat the lower pressing mold 4, and the pressure device 11 is used to pressurize the lower pressing mold 4. The high temperature and high pressure soften the sole, achieving a better bonding effect. After bonding is completed, the upper pressing mold 10 is detached from the lower pressing mold 4. At this time, under the elastic action of the ejector spring 24, the support plate 23 is pushed upward, and the support plate 23 lifts the bonded shoes for easy handling by the staff.

[0025] Example 2: Please refer to Figures 5-7 To achieve cooling after bonding, this embodiment provides the following technical solution: A storage tank 12 is fixedly installed at the middle position of the upper surface of the bearing turntable 3, and the storage tank 12 is provided with a first storage tank 1201 and a second storage tank 1202. The first storage tank 1201 stores coolant and is equipped with a stirring mechanism to accelerate cooling. A bent cooling pipe 13 is fixedly installed inside the lower end of the lower pressing mold 4, and the front end of the cooling pipe 13 is connected to the first storage tank 1201 inside the storage tank 12 through a first pump body 14. The stirring mechanism includes a horizontally mounted part of the pump body 14. The connecting rod 16 inside the storage tank 12 forms a through sliding structure with the connecting rod 16 and the storage tank 12. A cooling chip 15 is fixedly installed on the lower surface inside the first storage tank 1201. An agitator 17 is fixedly installed on the lower surface of the middle position of the connecting rod 16. A first magnetic block 18 is fixedly installed at the front end of the connecting rod 16. A return spring 19 located outside the connecting rod 16 is fixedly installed between the first magnetic block 18 and the storage tank 12. The positions of the first magnetic block 18 and the second magnetic block 20 correspond to each other. The first magnetic block 18 and the second magnetic block 20 repel each other magnetically. The second magnetic block 20 is fixedly installed on the upper surface of the mounting plate 21.

[0026] After bonding is completed, the first pump body 14 is turned on, so that the first pump body 14 delivers the coolant in the first storage tank 1201 to the cooling pipe 13. The cooling pipe 13 cools down the lower pressing mold 4 and the shoe, so that the sole of the shoe is quickly cooled and hardened after bonding, avoiding the deformation of the sole after removal. The coolant in the first storage tank 1201 is cooled by the cooling plate 15 to ensure its subsequent use effect. During the rotation of the bearing turntable 3, the storage box 12 in the middle of its upper surface is rotated. When the first magnetic blocks 18 on the left and right sides of the storage box 12 rotate to the position corresponding to the second magnetic blocks 20 on the mounting plate 21, the first magnetic blocks 18 push the connecting rod 16 to slide relative to the storage box 12 under the action of magnetic repulsion. During the movement, the connecting rod 16 drives the stirring plate 17 below to move. Then, with the help of the return spring 19, the connecting rod 16 is reset, and the stirring plate 17 moves back and forth. The stirring plate 17 stirs the coolant, which accelerates the cooling speed of the coolant by the cooling plate 15.

[0027] Example 3: Please refer to Figures 8-10 In order to achieve the purpose of bonding the sole and the upper, this embodiment provides the following technical solution, which specifically discloses: an atomizing nozzle 25 is fixedly installed on the outside of the side of the pressing mold 4, and the position of the atomizing nozzle 25 corresponds to the position of the receiving groove 5. A connecting pipe 26 is fixedly installed on the side of the atomizing nozzle 25. The connecting pipe 26 is connected to the second storage tank 1202 through the second pump body 27. The second storage tank 1202 stores adhesive remover. A stirring rod 28 for stirring the adhesive remover is rotatably installed inside the second storage tank 1202. A friction roller 29 is coaxially fixedly installed above the stirring rod 28. The friction roller 29 and the outer surface of the rear end of the connecting rod 16 are in contact and rub against each other.

[0028] After bonding is completed, the second pump body 27 is turned on, so that the second pump body 27 pressurizes and sprays the adhesive remover in the second storage tank 1202 through the connecting pipe 26 from the atomizing nozzle 25, thereby spraying the adhesive remover onto the surface of the support plate 23 and the inside of the receiving tank 5. The adhesive remover is used to remove any residual glue (glue may overflow during the bonding of the shoe sole) that may remain in the support plate 23 and the receiving tank 5. During the movement of the connecting rod 16, the friction force at the rear end drives the friction roller 29 to rotate, thereby causing the friction roller 29 to drive the stirring rod 28 to rotate. The stirring rod 28 agitates the adhesive remover in the second storage tank 1202, preventing the adhesive remover from settling due to prolonged storage.
