Description

Technical Field

[0001] This utility model relates to shoe processing equipment, specifically a shoe upper polishing device. Background Technology

[0002] In footwear manufacturing, the bonding of the upper to the outsole is a crucial step that directly affects the quality and durability of the finished shoe. To ensure a good bond, pre-bonding treatment of the upper is essential, especially the area where the upper contacts the outsole (i.e., the area to be processed on the upper). This area requires meticulous sanding and gluing before bonding.

[0003] In existing automated equipment, during the polishing process, the robotic arm and other equipment are usually placed in a protective box. This is convenient for the robotic arm to move the shoe last with the shoe upper attached, and also for the robotic arm to move the polishing wheel around the shoe upper processing area, as well as for the robotic arm to move the glue spray nozzle around the shoe upper processing area. However, this method has the following problems.

[0004] During grinding, the powder generated can easily get into the gaps of the robotic arm or drive components, affecting the operation of the equipment. To solve this problem, operators need to clean it regularly, and this must be done while the equipment is stopped, which seriously affects the continuity and efficiency of the production line.

Detailed Implementation

[0024] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0025] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0026] As described in the background section, in existing automated equipment, during the polishing process, the robotic arm and other equipment are generally placed in a protective box. This facilitates the movement of the shoe last with the shoe upper attached by the robotic arm, and also makes it easier to move the polishing wheel around the shoe upper processing area and the robotic arm to move the glue spray nozzle around the shoe upper processing area. However, this method has the following problems.

[0027] During grinding, the powder generated can easily get into the gaps of the robotic arm or drive components, affecting the operation of the equipment. To solve this problem, operators need to clean it regularly, and this must be done while the equipment is stopped, which seriously affects the continuity and efficiency of the production line.

[0028] For the reasons mentioned above, such as Figures 1-7 As shown, this embodiment provides a shoe upper polishing device, including a box body 100 with an upper opening. A box cover 200 is provided at the opening end of the box body 100. Several sandblasting nozzles 500 are provided inside the box body. The several sandblasting nozzles 500 are arranged around the shoe upper processing area 401 placed inside the box body. The sandblasting range formed by the several sandblasting nozzles covers the shoe upper processing area 401. The shoe upper processing area 401 is the area where the shoe upper 400 contacts the outsole.

[0029] The aforementioned technical features enable sandblasting of the shoe upper processing area in a closed environment, facilitating subsequent gluing. The use of sandblasting solves the problem of complex traditional grinding wheel drive structures. Furthermore, the use of a closable box allows the sandblasting process to be carried out in a closed environment, preventing debris or sandblasting from affecting the environment and equipment. In use, the box lid is first opened, the shoe upper is moved to the designated position using the shoe last 300, the lid is closed, the sandblasting nozzle is activated, and the shoe upper processing area is sandblasted. After the designated processing time, the box lid is opened, the shoe last 300 is moved, and the processed shoe upper is removed.

[0030] To better control the movement of the shoe last, the upper part of the shoe last is connected to a moving device, which drives the shoe last to move up and down and / or left and right. The moving device can be a robotic arm or a cylinder assembly, wherein the cylinder assembly includes a lateral moving cylinder 800 and a longitudinal moving cylinder 700. The telescopic rod of the longitudinal moving cylinder is fixedly connected to the upper part of the shoe last, the cylinder body of the longitudinal moving cylinder is fixedly connected to the telescopic rod of the lateral moving cylinder, and the cylinder body of the lateral moving cylinder is connected to an external fixed base.

[0031] In order to allow the nozzles to better sandblast and polish the shoe upper processing area, in one embodiment, four sandblasting nozzles 500 are provided in the box. The four sandblasting nozzles are respectively located on the four sides of the shoe upper processing area, and the sandblasting range of the four sandblasting nozzles covers the shoe upper processing area. In this embodiment, the sandblasting nozzles are mostly fan-shaped nozzles to cover the polishing area with a larger sandblasting range.

[0032] In the above embodiments, if only four sandblasting nozzles are used, it is easy to cause uneven sandblasting. Therefore, in order to overcome the problem of sandblasting layout, in another embodiment, several sandblasting nozzles 500 are arranged on the four sides of the shoe upper processing area. The sandblasting angle or range of the several sandblasting nozzles on each side is different, so that the several sandblasting nozzles on each side can cover the side, and thus all four sides can be covered. For example, a rectangular frame 600 is provided on the inner wall of the box, and several sandblasting nozzles 500 are installed on each side of the rectangular frame. The sandblasting distance or sandblasting intensity of each sandblasting nozzle can be adjusted.

[0033] The aforementioned technical features, by installing several sandblasting nozzles around the shoe upper processing area, can fully cover the shoe upper processing area, improve the quality of sandblasting, and avoid the problem of uneven sandblasting.

[0034] To facilitate the discharge of sprayed sand and debris, in one embodiment, a discharge port 101 is provided at the lower part of the box. The discharge port is connected to a sand recycling device via a pipe, wherein debris in the sand can be cleaned by air flotation, and the sand can be recycled using an existing sand recycling device.

[0035] To ensure that sandblasting is performed in a closed environment, in one embodiment, the box cover consists of two cover plates 201, the inner edges of which have a mating arc surface 2011 that can fit against the shoe upper attached to the shoe last. This method ensures that the box remains sealed during sandblasting, reducing the impact of sand or debris flying or splashing on the working environment and equipment.

[0036] To allow for adjustment of the sandblasting thickness using the sandblasting nozzle, in one embodiment, the rectangular frame is connected to a vertical drive structure. For example, this vertical drive structure can be a rack and pinion structure or a telescopic cylinder, preferably a telescopic cylinder 900. Figure 9 As shown. To prevent sand from entering the telescopic cylinder's telescopic gap (such as the gap between the telescopic rod and the telescopic cylinder) and affecting or damaging the telescopic rod, a telescopic sleeve 902 is installed around the telescopic rod. To mitigate the impact of sandblasting on the cylinder body, the telescopic cylinder body is also equipped with a cylinder body sleeve 901. The telescopic sleeve is connected to the cylinder body sleeve, as shown. Figure 10 As shown. In this embodiment, in order to fully cover the upper processing area, sandblasting nozzles can be added. In order to better adapt to the concave curvature of the upper processing area, the distance between the sandblasting nozzles and the upper processing area can also be adjusted.

[0037] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
