Technical Field

[0001] The utility model relates to the technical field of sports shoe production, in particular to a fixing device used for producing sports shoe uppers. Background Art

[0002] Sports shoes are shoes designed and manufactured according to the characteristics of people participating in sports or traveling. They can enhance elasticity and prevent ankle injuries. During the production and processing of sports shoes, in order to facilitate the processing of the sports shoe uppers, it is necessary to use a fixing device for the production of sports shoe uppers to shape and fix the sports shoe uppers so that the uppers can be processed or painted.

[0003] After searching, the Chinese patent application No. 202221031829.4 discloses a fixing device for producing sports shoe uppers, including a fixing base, a transverse fixing assembly and a longitudinal fixing assembly, wherein two groups of columns are welded on the upper surface of the fixing base and are respectively located at both ends, a workbench is installed between the two groups of columns, the transverse fixing assembly is installed on the workbench, and the longitudinal fixing assembly is installed between the two groups of columns; through the cooperation between the longitudinal fixing assembly, the upper positioning model, the two groups of columns and the transverse fixing assembly, after the upper is installed on the upper positioning model, the two ends of the upper can be pressed against the upper positioning model through the longitudinal fixing assembly, and then the two sides of the upper can be pressed against the upper positioning model through the transverse fixing assembly, so that the upper can be clamped and fixed, and workers do not need to hold the upper for a long time for processing, which improves the overall quality of the shoes and reduces the workload of workers at the same time;

[0004] The above patent still has the following deficiencies: (1) The defect of easily damaging the upper. Since the upper of sports shoes is usually made of relatively soft artificial leather, synthetic fiber, leather and other materials, when the pressure of the device fixing the upper is too large, it is easy to cause the pressing plate to damage the upper, causing indentations on the upper, affecting the quality and sales of sports shoes;

[0005] (2) It is not convenient to fix on the shoe upper. The existing device is usually directly mounted on the outside of the shoe mold. As a result, during the process of fixing the shoe upper, the shoe upper is easy to slide on the outside of the shoe mold and is not easy to stick to the surface of the shoe mold, which is not convenient for processing.

[0006] Therefore, there is an urgent need for a fixing device for producing sports shoe uppers to solve the above problems. Utility Model Content

[0007] The purpose of the utility model is to address the existing defect of easily damaged uppers. Since the uppers of sports shoes are usually made of relatively soft artificial leather, synthetic fiber, genuine leather and other materials, when the pressure of the device fixing the upper is too large, it is easy to cause the pressing plate to damage the upper, causing indentations on the upper, affecting the quality and sales of the sports shoes.

[0008] In order to achieve the above-mentioned invention object, the utility model provides the following technical solutions:

[0016] Through the above technical solution, the pressure transmitted from the movable frame to the pressing plate is buffered by the buffer spring, thereby reducing the pressure caused by the pressing plate on the shoe upper.

[0017] As a preferred technical solution of the present application, an external thread is arranged on the outer wall of the screw rod, and an internal thread cooperating with the external thread is arranged inside the screw sleeve.

[0018] Through the above technical solution, the threaded sleeve is rotated to move left and right on the outer side of the screw rod, thereby squeezing or releasing the buffer spring and adjusting the elastic force of the buffer spring.

[0019] As a preferred technical solution of the present application, a sliding structure is formed between the guide rod and the movable frame, and the buffer springs are symmetrically distributed on the vertical center line of the movable frame.

[0020] Through the above technical solution, the guide rod slides inside the movable frame, so that the buffer spring is not easy to cause the pressing plate to vibrate.

[0022] According to the technical solution, the air inside the cavity is extracted through the connecting pipe by a vacuum pump, so that suction is generated on the surface of the metal mesh, and the suction is used to make the shoe upper close to the surface of the metal mesh.

[0023] As a preferred technical solution of the present application, the metal mesh is arranged in several groups on the outside of the shoe mold, and the several groups of metal mesh are distributed at equal intervals on the outside of the shoe mold.

[0024] Through the above technical solution, the shoe upper can be adsorbed and fixed in all directions through multiple groups of metal meshes.

[0025] Compared with the prior art, the utility model has the following beneficial effects:

[0026] In the scheme of this application:

[0027] The pressure transmitted from the moving frame to the pressing plate is buffered by the buffer spring, thereby reducing the pressure caused by the pressing plate on the shoe surface. The rotating screw sleeve moves left and right on the outside of the screw rod to adjust the elastic force of the buffer spring, thereby realizing the pressure buffering function of the device, facilitating the buffering of the pressure on the shoe surface, preventing the shoe surface from being indented due to the pressure, ensuring the quality of the shoe surface, and enhancing the functionality of the device.

[0034] To make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0035] like Figure 1-4 As shown, the fixing device for producing sports shoe uppers proposed in this embodiment includes a bottom plate 1, a support frame is provided at the bottom of the bottom plate 1, which is not shown in the figure, and further includes:

[0036] The slide rail 2 is fixed on the top of the bottom plate 1, and the outer side of the slide rail 2 is sleeved with a slide sleeve 9, and the top of the slide sleeve 9 is fixed with a moving frame 3;

[0037] The buffer structure 4 is arranged on one side of the mobile frame 3, wherein the buffer structure 4 includes a guide rod 403 inserted into the mobile frame 3, a limit block 401 fixed on one side of the guide rod 403, a buffer spring 402 sleeved on the outside of the guide rod 403, and an adjustment component arranged on the other side of the guide rod 403;

[0038] The pressing plate 5 is installed on one side of the buffer structure 4;

[0039] A top plate 8 is fixed to the top of the bottom plate 1, and pneumatic telescopic rods 10 are installed on both sides of the bottom end of the top plate 8, and a double-stroke cylinder 11 is fixed to the bottom end of the top plate 8;

[0040] The shoe mold 6 is installed on the top of the top plate 8, and a fixing structure 7 is arranged inside the shoe mold 6.

[0041] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the adjustment component includes a screw 406 fixed on one side of the guide rod 403, a screw sleeve 404 sleeved on the outside of the screw 406 and connected to the buffer spring 402, and a connecting plate 405 fixed on one side of the screw 406 and connected to the pressing plate 5. The outer wall of the screw 406 is provided with an external thread, and the interior of the screw sleeve 404 is provided with an internal thread that cooperates with the external thread. A sliding structure is formed between the guide rod 403 and the movable frame 3, and the buffer spring 402 is symmetrically distributed on the vertical center line of the movable frame 3. The buffer spring 402 buffers the pressure transmitted from the movable frame 3 to the pressing plate 5 by contraction deformation, thereby reducing the pressure caused by the pressing plate 5 on the shoe surface. At the same time, the guide rod 403 slides inside the movable frame 3, so that the buffer spring 402 is not easy to drive the pressing plate 5 to shake. By rotating the screw sleeve 404 to move left and right on the outside of the screw 406, the buffer spring 402 is squeezed or released to adjust the elastic force of the buffer spring 402.

[0042] like Figure 1 , Figure 2 and Figure 3 As shown, as a preferred embodiment, on the basis of the above method, further, the fixed structure 7 includes a vacuum pump 701 fixed to the bottom end of the base plate 1, a metal mesh 703 installed on the top of the vacuum pump 701 and penetrating the base plate 1, a cavity 704 opened in the shoe mold 6, a metal mesh 703 installed on the surface of the shoe mold 6, and a filling block 705 arranged in the shoe mold 6 and connected to the connecting pipe 702. Several groups of metal mesh 703 are arranged on the outside of the shoe mold 6, and several groups of metal mesh 703 are distributed at equal intervals on the outside of the shoe mold 6. Start the vacuum pump 701, so that the vacuum pump 701 draws air from the cavity 704 through the connecting pipe 702, so that suction is generated on the surface of the metal mesh 703. When the upper is sleeved on the outside of the shoe mold 6, the suction is used to make the upper close to the surface of the metal mesh 703 to avoid sliding or bulging of the upper.

[0043] Specifically, when the fixing device for producing sports shoe uppers is used: the upper is placed on the position of the shoe mold 6, and the fixing structure 7 is used to suck the upper to preliminarily fix the position of the upper, and at the same time, the upper is tightly attached to the surface of the shoe mold 6 to prevent wrinkles, and the pneumatic telescopic rod 10 and the double-stroke cylinder 11 are started to contract, so that the movable frame 3 drives the pressing plate 5 to press and fix the position of the upper, and at the same time the buffer structure 4 buffers the pressure to prevent damage to the upper, and the movement of the movable frame 3 is guided by the sliding sleeve 9 sliding on the outer side of the slide rail 2.

[0044] When the pressure of the moving frame 3 on the shoe upper is too large after passing through the pressing plate 5, the buffer spring 402 contracts and deforms to buffer the pressure transmitted by the moving frame 3 to the pressing plate 5, thereby reducing the pressure of the pressing plate 5 on the shoe upper. At the same time, the guide rod 403 slides inside the moving frame 3, so that the buffer spring 402 is not easy to drive the pressing plate 5 to shake. The screw sleeve 404 is rotated to move left and right on the outside of the screw rod 406 to squeeze or release the buffer spring 402, thereby adjusting the elastic force of the buffer spring 402.

[0045] Start the vacuum pump 701 to extract the air inside the cavity 704 through the connecting pipe 702, so that suction is generated on the surface of the metal mesh 703. When the shoe upper is put on the outside of the shoe mold 6, the suction is used to make the shoe upper close to the surface of the metal mesh 703 to prevent the shoe upper from sliding or bulging.

[0046] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
