Description

Technical Field

[0001] This utility model relates to the field of shoe sole processing technology, specifically to a pressing device for a sole pressing machine. Background Technology

[0002] A sole press is a mechanical device used in the shoe manufacturing process to press the sole and upper together. The pressure is adjusted by an external handle or a fully automatic control system, and the sole is pressed using a hydraulic or pneumatic system. During the pressing process, the sole press will press the sole according to the preset pressure and temperature to ensure a firm bond between the sole and the upper.

[0003] Existing pressing machines use multiple rubber blocks and hydraulic cylinders to press the soles together. Adhesive is first applied to the contact surface between the sole and the upper. However, if too much adhesive is applied during the pressing process, it can easily be squeezed out of the gap between the sole and the upper and adhere to the surface of the pressing blocks, affecting the bonding process in the next step. This requires manual cleaning of the pressing blocks, which is quite troublesome.

[0004] Based on the above problems, a technical solution for a glue removal device for the pressing device of a bottom pressing machine is proposed. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the prior art by proposing a pressing device for a bottom pressing machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a pressing device for a sole pressing machine, comprising a frame, wherein a plurality of worktables are provided on the frame, and a plurality of pressing blocks for clamping the sole and the upper are slidably disposed within the worktables, wherein the plurality of pressing blocks have grooves at the connection between the sole and the upper, and the plurality of grooves are connected to a heating device.

[0007] The present invention is further configured such that: the pressure block near the side wall of the frame has an air inlet and an air return hole in the groove; the heating device includes an air pump and a heating element; the air pump and the heating element are connected by a pipe; and the heating element is connected to the air inlet and the air return hole by a gas pipe respectively.

[0008] The present invention is further configured such that: the heating element is an electric heating wire, and is connected to a controller for adjusting the heating temperature.

[0009] The present invention is further configured such that all the gas pipes are retractable telescopic pipes.

[0010] The present invention is further configured such that: a lifting device is provided below the worktable, and a pressing device is provided above the worktable; the pressing device is rotatably mounted on the frame via a rotating shaft; when the pressing device rotates to the shoe surface, the lifting device drives the worktable to rise to complete the pressing.

[0011] The present invention is further configured such that the surface of the pressing block is coated with a Teflon coating.

[0012] In summary, this utility model has the following beneficial effects: the groove design avoids glue from adhering directly to the surface of the pressing block, reducing the difficulty of cleaning, while the heating device can accelerate the solidification speed of the overflowing glue, reduce the flow time of the overflowing glue on the side of the shoe, and further reduce the cleaning cost.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] A pressing device for a bottom pressing machine, such as Figures 1 to 3As shown, the device includes a frame 1, on which several worktables 2 are provided. Several pressure blocks 3 for clamping the sole and upper of the shoe are slidably arranged in the worktables 2. The pressure blocks 3 have grooves 31 at the connection between the sole and the upper. The grooves 31 are connected to a heating device. In this embodiment, the surface of the pressure block 3 is coated with a Teflon coating. The Teflon coating has excellent anti-stick properties and can effectively prevent glue from adhering to the surface of the pressure block 3. The pressure block 3 located on the side of the shoe is composed of several small pressure blocks 3 that can be moved at will to accommodate shoes of different sizes.

[0019] Practical effects: The design of the groove 31 prevents glue from adhering directly to the surface of the pressure block 3, reducing the difficulty of cleaning, while the heating device can accelerate the solidification speed of the overflowing glue, reduce the time that the overflowing glue can flow on the side of the shoe, and further reduce the cleaning cost.

[0020] like Figures 1 to 3 As shown, the pressure block 3 near the side wall of the frame 1 has an air inlet 311 and an air return 312 in the groove 31. The heating device includes an air pump 4 and a heating element 5. The air pump 4 and the heating element 5 are connected by a pipe. The heating element 5 is connected to the air inlet 311 and the air return 312 through the air pipe 6. Specifically, the heating element 5 uses an electric heating wire and is connected to a controller 7 for adjusting the heating temperature. The controller 7 adjusts the heating temperature to achieve precise control of the hot air temperature, ensuring that the glue can cure quickly at a suitable temperature. The air pipes 6 are all telescopic tubes, which can flexibly adjust the delivery distance and angle of the hot air.

[0021] like Figures 1 to 3 As shown, a lifting device 8 is provided below the worktable 2, and a pressing device 9 is provided above the worktable 2. The pressing device 9 is rotatably mounted on the frame 1 via a rotating shaft 10. When the pressing device 9 rotates onto the shoe surface, the lifting device 8 drives the worktable 2 to rise to complete the pressing.

[0022] In this embodiment, the air pump 4 is connected to the air pipe 6 via a gas exchanger. Initially, both the air inlet 311 and the air outlet 312 are closed. When the pressure block 3 and the pressing device 9 work together to apply pressure to the shoe, the air inlet 311 opens, allowing the air pump 4 to transport hot air into the groove 31. At this time, the air outlet 312 is connected to the outside air. After a preset time, the air inlet 311 is connected to the outside air, and the air outlet 312 is connected to the air pump 4. The air pump 4 begins to slowly extract the hot air from the groove 31. After the hot air is completely discharged, the air inlet 311 and the air outlet 312 return to their initial state, and the pressure block 3 and the pressing device 9 release the pressure on the shoe, allowing the shoe to be easily removed.

[0023] Specific operation: When the pressing device 9 rotates with the rotating shaft 10 to directly above the shoe, the lifting device 8 drives the worktable 2 to rise, realizing the pressing of the sole and the upper. During this process, the glue overflowing at the connection between the sole and the upper should have a certain stickiness, adhere to the connection, and quickly solidify at the connection with the flowing hot air. This can not only strengthen the connection stability between the sole and the upper, but also prevent the glue from overflowing and adhering to the surface of the pressing block 3.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0025] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
