Description

Technical Field

[0001] This utility model belongs to the field of bottom pressing machine technology, specifically relating to a side adaptive clamping mechanism for a bottom pressing machine. Background Technology

[0002] A sole press is a specialized piece of machinery used in the footwear and leather goods processing industries to pressurize and bond shoe uppers or leather upholstery with soles or insoles. Its core function is to achieve a firm bond between the shoe upper and sole through precise control of pressure, temperature, and time, ensuring the structural stability, wear resistance, and wearing comfort of the finished shoe. It is a key piece of equipment in the shoe production line that connects upper processing and finished product assembly.

[0003] Specifically, when using a sole presser to press and bond the sole or leather material, in order to prevent the side of high-top shoes from shifting and the thick sole from warping, a side holding mechanism is needed to assist in fixing it. Currently, the mainstream side holding method adopts a symmetrical structure of "two movable clamping surfaces as a group". The two clamping surfaces are driven by a cylinder to move from both sides towards the middle to achieve lateral fixation of the upper or sole. However, this structure has a significant drawback: the two movable clamping surfaces are driven independently. If the pressure of the cylinder on one side fluctuates, or if the force at the contact point between the clamping surface and the material is uneven, the clamping block is prone to rotating at a slight angle around the connecting shaft. This rotation prevents the two clamping surfaces from being completely parallel and in contact with the side of the material, resulting in gaps and uneven pressure distribution on the clamping surfaces. This can lead to wrinkles on the shoe upper side and misalignment of the sole edge, and may also damage the material surface due to excessive clamping in some areas, or cause the material to shift when the main pressure head applies pressure due to insufficient clamping force in some areas, reducing the bonding accuracy of the finished product and increasing the labor costs of subsequent trimming and rework. Utility Model Content

[0004] The purpose of this invention is to provide a side-adaptive clamping mechanism for a sole pressing machine. This mechanism addresses the problem that when two movable clamping surfaces are driven independently, fluctuations in the pressure of one cylinder or uneven force at the contact point between the clamping surface and the material can easily cause the clamping block to rotate slightly around the connecting shaft. This rotation prevents the two clamping surfaces from being completely parallel and in contact with the material's side, resulting in gaps and uneven pressure distribution. This not only leads to wrinkles on the shoe upper side and misalignment of the sole edge, but also may cause damage to the material surface due to excessive clamping in certain areas, or displacement of the material when the main pressure head applies pressure due to insufficient clamping force in certain areas. This reduces the bonding accuracy of the finished product and increases the labor costs for subsequent trimming and rework.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a side adaptive clamping mechanism for a bottom pressing machine, comprising a bottom pressing machine body and a worktable installed inside the bottom pressing machine body, wherein an upper pressing head is installed on the top of the inner wall of the bottom pressing machine body near the worktable, an end clamping cylinder is connected to the surface of the worktable, and an end clamping head is connected to the output end of the end clamping cylinder. The surface of the workbench is connected to a cylinder seat, and a cylinder piston rod is installed inside the cylinder seat. A cylinder front cover plate is connected to one side of the cylinder seat, and a clamping cylinder rod connecting plate is connected to the other side of the cylinder front cover plate. A clamping cylinder connecting plate is connected to the other side of the clamping cylinder rod connecting plate, and a movable clamping plate is connected to one side of the clamping cylinder connecting plate. A cylinder piston positioning plate is connected to one end of the cylinder piston rod, and cylinder upper cover plates on both sides of the workbench are connected to the top of the cylinder seat. A cylinder piston is installed inside the cylinder seat, and the rear cylinder rear cover plates on both sides of the workbench are connected to the sides of the cylinder seat.

[0006] In order to facilitate the assembly of the clamping cylinder rod connecting plate, as a side adaptive clamping mechanism of the bottom pressing machine of this utility model, preferably, the cylinder piston positioning plate is connected to the top opening of the clamping cylinder rod connecting plate by bolts.

[0007] In order to reduce the size of the gap, as a side adaptive clamping mechanism of the bottom pressing machine of this utility model, preferably, two pins are connected through the surface of the clamping cylinder rod connecting plate, and the pins are movably connected to the clamping cylinder connecting plate.

[0008] In order to improve the processing quality, as a side adaptive clamping mechanism of the bottom pressing machine of this utility model, the movable clamping plate is preferably made of silicone.

[0009] To facilitate the assembly of the fixing clamping plate, as a side adaptive clamping mechanism of the bottom pressing machine of this utility model, preferably, a receiving plate is connected to the center of the clamping cylinder rod connecting plate, and a fixing clamping plate is fixedly connected to one end of the receiving plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This invention places the shoe sole on a workbench. The end-clamping cylinder drives the end chuck to clamp the end of the sole and the heel area, while the upper pressure head clamps the upper part of the sole. Simultaneously, the cylinder inside the drive cylinder seat propels the cylinder front cover forward, which in turn propels the clamping cylinder connecting plate at one end of the clamping cylinder rod connecting plate. At this point, two movable clamping plates in a set of side clamping structures rotate along the pin shaft, while one fixed clamping plate remains stationary. The angle between the two movable clamping plates and the fixed clamping plate is smaller than that between two independent movable clamping plates, thus ensuring uniform force on the clamping surface, guaranteeing the precision of the pressing and pressing, and improving the quality of the pressing.

An end clamping cylinder 4 is connected to the surface of the worktable 2. An end clamping head 5 is connected to the output end of the end clamping cylinder 4. The specific model of the bottom pressing machine body 1 is: wall-mounted bottom pressing machine 918C. A cylinder seat 24 is connected to the surface of the workbench 2. A cylinder piston rod 25 is installed inside the cylinder seat 24. A cylinder front cover plate 26 is connected to one side of the cylinder seat 24. A clamping cylinder rod connecting plate 27 is connected to the other side of the cylinder front cover plate 26. A clamping cylinder connecting plate 28 is connected to the other side of the clamping cylinder rod connecting plate 27. A movable clamping plate 29 is connected to one side of the clamping cylinder connecting plate 28. A cylinder piston positioning plate 30 is connected to one end of the cylinder piston rod 25.

[0020] Preferably, the cylinder piston positioning plate 30 is connected to the top opening of the clamping cylinder rod connecting plate 27 by bolts. In actual use, by connecting the cylinder piston positioning plate 30 to the clamping cylinder rod connecting plate 27, it is convenient to move the clamping cylinder rod connecting plate 27 when the cylinder is started. Preferably, two pins 34 are connected through the surface of the clamping cylinder rod connecting plate 27, and the pins 34 are movably connected to the clamping cylinder connecting plate 28. In actual use, by rotating the two movable clamping plates 29 along the pins 34, it is convenient to clamp and stabilize the shoe sole from the side.
