Description

Technical Field

[0001] The utility model relates to the field of shoe-making machines, and particularly relates to an adjustable shoe head wrapping structure for a sole pressing machine. Background Technique

[0002] After the raw materials go through the operations of cutting, sewing the upper, and stretching the upper, the shoe has a basic shape. It can only become a complete shoe after the upper and sole are bonded together. The bonding of the upper and sole is the process of bonding the outer sole, the upper edge of the stretched upper, and the insole together with an adhesive. The process of bonding the upper and sole is an important process in the shoe-making technology. There are various methods for bonding the upper and sole, and the five basic processes are gluing, vulcanization, molding, injection, and stitching (therefore, semi-automatic equipment is generally used in cooperation with workers for processing). Among them, the gluing process is the most commonly used one in the current market. Briefly understood, it can be that after the sole is placed in the lower mold, the upper with a shoe last is placed on the upper wall of the sole, and then pressure is applied to make the two fit together.

[0003] The upper cover of the existing sole pressing machine is generally provided with a shoe head wrapping structure to position the sole and the upper, so as to ensure the tight fit between the sole and the upper and prevent wrinkling during processing. However, the shoe head wrapping structure generally adopts a replaceable structure to adapt to different uppers (adjust or replace different positions according to the length of the shoes). It is necessary to disassemble the shoe head wrapping structure for replacement, which is relatively troublesome to use. For some manufacturers, there may only be processing workers. In this case, it is necessary for the equipment manufacturer to go and install it, resulting in low efficiency. Summary of the Utility Model

[0004] The main purpose of the utility model is to propose an adjustable shoe head wrapping structure for a sole pressing machine, aiming to solve the above technical problems and make the shoe head wrapping structure easy to adjust.

[0005] To achieve the above purpose, the utility model proposes an adjustable shoe head wrapping structure for a sole pressing machine, including an upper cover. The upper cover is installed on the bottom mold. The upper cover can be switched between a position where it is closed with the bottom mold and a position away from the bottom mold. A wrapping part is provided on the lower wall of the upper cover and slides along the length direction of the receiving groove. The wrapping part is provided with a profiling groove adapted to the shape of the upper. A second driving device for driving the wrapping part to move is provided on the upper wall of the upper cover.

[0006] The technical solution of the utility model realizes the horizontal movement of the wrapping part through a relatively small sliding structure, so as to meet the wrapping of uppers with different lengths, reduce the steps of replacing the wrapping part, and the wrapping part has a certain elasticity. When processing uppers with the same shape (i.e., the same style), only need to adjust the relative position of the wrapping part through the second driving device to make it fit. The structure is simple and stable. Description of the Drawings

[0030] As Figures 1 to 9 shown, an adjustable shoe head wrapping structure for a sole pressing machine includes:

[0031] A bottom mold 1, and the bottom mold 1 is provided with a receiving groove 10 for placing a shoe last.

[0032] A guiding frame 2, the bottom end of the guiding frame 2 is arranged at a position of the bottom mold 1 away from the receiving groove 10, and the top end of the guiding frame 2 is provided with a top seat 11.

[0033] An upper cover 3, the upper cover 3 is arranged on the guiding frame 2 and can slide vertically along its height direction. The top seat 11 is provided with a first driving device 4, and the first driving device 4 is used to drive the upper cover 3 to move vertically.

[0034] In the actual design, the vertical sliding can be achieved through the cooperation of the guide frame 2 and the upper cover 3. Furthermore, a larger opening and closing degree can be realized between the upper cover 3 and the bottom die 1, which is convenient for the staff to observe the accommodating groove 10, making the alignment of the shoe upper and the sole more accurate and ensuring the stability of the pressing. At the same time, the lower wall of the upper cover 3 can facilitate the installation and adjustment of the pressing rod 5 and the shoe upper covering structure, thereby improving the applicability of the sole pressing machine, production efficiency and use convenience.

[0035] Specifically, the guide frame 2 includes four guide rods 21 arranged at intervals and a guide sleeve 22 slidably installed on the guide rods 21. The guide rods 21 are arranged between the bottom die 1 and the top seat 11, and the guide sleeve 22 is arranged on the upper cover 3, thus realizing the vertical sliding of the upper cover 3 with better stability.

[0036] More specifically, the first driving device 4 is a hydraulic driving motor arranged on the lower wall of the top seat 11, and the driving end of the hydraulic driving motor is connected to the upper wall of the upper cover 3. This embodiment is not illustrated. The upper cover 3 can be moved quickly and stably through the hydraulic driving motor, but the cost is relatively high. Especially for some structures that need to be sealed, higher requirements are imposed on the pressure stability.

[0037] In the embodiment of the present utility model, the first driving device 4 includes a telescopic motor 42 and a connecting rod 41 connected to the driving end of the telescopic motor 42. The lower end of the connecting rod 41 is connected to the upper end of the upper cover 3. Through the cooperation of the connecting rod 41 and the telescopic motor 42, the upper cover 3 is lifted by using the lever principle, and at the same time, the combined pressure when the upper cover 3 is matched with the bottom die 1 is ensured, guaranteeing the sealing performance.

[0038] Specifically, the connecting rod 41 includes a first rod body 411 pivotally connected to the lower end of the upper cover 3 and a second rod body 412 pivotally connected to the upper end of the first rod body 411. The upper end of the rod body is pivotally connected to the lower wall of the top seat 11.

[0039] In the embodiment of the present utility model, the telescopic motor 42 is pivotally installed on the top seat 11, and the driving end of the telescopic motor 42 is pivotally connected to the middle of the second rod body 412. By arranging the telescopic motor 42 in a swinging manner, both the vertical stroke of the upper cover 3 and the pressing degree can be ensured.

[0040] Specifically, the telescopic motor 42 is inclinedly arranged on the top seat 11, so that the opening and closing of the upper cover 3 can be realized with a relatively small pressure.

[0041] In the embodiment of the present utility model, a connecting shaft is arranged between the first rod body 411 and the second rod body 412, and a blocking portion 413 is arranged on one side of the connecting shaft. The blocking portion 413 is used for the limit when the cover body is closed, and thus the limit of the pressing seat 52 is realized through a predetermined swinging angle.

[0042] Specifically, the upper cover 3 is provided with an upwardly protruding extension portion 31. An inner cavity 32 is formed between the extension portion and the lower wall of the upper cover 3. A vertically adjustable pressing rod 5 is arranged in the inner cavity 32. The pressing rod 5 includes a main rod 51 and a pressing seat 52 swingably mounted at the lower end of the main rod 51. The pressing seat 52 swings by a predetermined amplitude around the axis of the main rod 51, and the swing amplitude is less than 25 degrees. Through the swing by the predetermined amplitude, the shoe last can be limited. At the same time, the setting of the inner cavity 32 also provides a predetermined swing range for the pressing seat 52, so that the shoe last can be closely fitted, effectively ensuring the installation stability.

[0043] Specifically, a limiting groove 61 is provided at the upper end of the pressing seat 52. The main rod 51 is provided with a spherical portion 62 extending into the limiting groove 61. The spherical portion 62 extends into the limiting groove 61 and swings with the end of the limiting groove 61 as the limit.

[0044] In the embodiment of the present utility model, the pressing seat 52 rotates 360 degrees with the axis of the spherical portion 62 as the reference. Therefore, regardless of the position of the shoe last, the pressing seat 52 can achieve the fitting degree with the shoe last according to the shape or inclination of the shoe last.

[0045] Specifically, the upper cover 3 is provided with a threaded hole 100. The main rod 51 is provided with a threaded portion matching the threaded hole 100. A nut matching the threaded portion is provided at the upper end of the pressing rod 5. By adjusting the relative position of the threaded portion, the relative height of the main rod 51 is adjusted. At the same time, the nut is used for adjustment and fixation, with a simple structure and low production cost.

[0046] In the embodiment of the present utility model, the bottom wall of the pressing seat 52 is assembled by a plurality of concentrically arranged ring rings 71. The plurality of ring rings 71 are spaced apart and a groove 72 is provided between two ring rings 71. The groove is provided with an anti-slip pad, thus ensuring the positioning of the shoe last.

[0047] Specifically, the lower wall of the upper cover 3 is provided with a covering portion 8 sliding along the length direction of the receiving groove 10. The covering portion 8 is provided with a profiling groove 81 adapted to the shape of the shoe upper. The upper wall of the upper cover 3 is provided with a second driving device for driving the covering portion 8 to move. By adjusting the relative position of the covering portion 8, the fitting of shoe uppers with different lengths is realized, the production of templates can be reduced, that is, one set of molds can be applicable to the processing of the same shoe upper with different sizes, effectively saving the template cost and replacement time, effectively improving the production efficiency, and the adjustment is convenient.

[0048] In the embodiment of the present utility model, the lower wall of the upper cover 3 is provided with a horizontal guide rail 91. The covering portion 8 is provided with a horizontal slider 92 matching the horizontal guide rail 91, thus ensuring the stable movement of the covering portion 8.

[0049] Specifically, the horizontal slider 92 is provided with screw through holes, and the covering part 8 is provided with screw holes matching with the screw through holes. After a screw passes through the screw through holes, it is screwed onto the screw holes.

[0050] In the embodiment of the present invention, the second driving device is a rotating device provided on the upper wall of the upper cover 3. The rotating device is provided with a shaft portion extending into the inner wall of the upper cover 3. The shaft portion is provided with a driving gear 103, and the covering part 8 or the slider is provided with a rack 102 matching with the driving gear. Through the meshing of the gear and the rack, the covering part 8 is driven to move along the horizontal slider 92, thereby realizing the position adjustment of the covering part 8.

[0051] Specifically, the rotating device is a rotating servo motor 101 or a manual screw rod. When it is a manual screw rod, a locking nut can be set to fix the manual screw rod. When it is a rotating servo motor 101, its built-in locking structure is provided, thereby realizing the limit of the rack.

[0052] Among them, by driving the upper cover 3 to move through the first driving device 4, a larger opening degree can be realized, which facilitates the maintenance or disassembly and inspection of the covering part 8 and the pressing seat 52.

[0053] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
