Description

Technical Field

[0001] This utility model belongs to the field of shoemaking technology, specifically relating to a shoe last placement rack for nailing insoles. Background Technology

[0002] "Nail-on insole" is an important step in the shoe manufacturing process. Specifically, it involves using a pneumatic nail gun to temporarily fix the insole to the shoe last. In subsequent sewing, gluing, or other processes, the fixed insole reduces the time workers spend adjusting and correcting, making the operation simpler. It also reduces errors or asymmetries caused by insole movement, ensuring that the shape and structure of the shoe remain consistent throughout the manufacturing process.

[0003] Currently, when attaching the insole, workers typically temporarily fix the shoe last to a post. The top surface of the shoe last has an insertion hole, and the top of the post is fixed with a shoe last fixing post that matches the insertion hole, such as... Figure 1 As shown, inserting the shoe last's holes into the shoe last fixing posts inverts the shoe last. The worker then accurately places the insole onto the bottom of the shoe last and secures it with a pneumatic nail gun. However, this method is inefficient because:

[0004] Firstly, the shoe last insertion hole needs to be aligned downwards with the shoe last fixing post in order to successfully insert the shoe last onto the post. However, because the shoe last insertion hole is facing downwards, workers cannot observe the position of the shoe last insertion hole during operation, and sometimes multiple adjustments are required to align the shoe last insertion hole with the shoe last fixing post, resulting in low efficiency.

[0005] Secondly, the way the insertion hole and the fixing post work together allows the shoe last to rotate on the post. Therefore, different shoe lasts have different postures on the post. Each time, the worker needs to adjust the position of the shoe last or the position of the insole to ensure that the insole is accurately placed on the bottom of the shoe last. The operation is cumbersome and results in low efficiency. Utility Model Content

[0006] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide a shoe last placement rack for nailing insoles, thereby simplifying operation and improving efficiency.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a shoe last holder for nailing insoles, comprising a rectangular frame and a dividing rod fixed to the top surface of the frame; the dividing rod divides the rectangular cutout on the top surface of the frame into two right-angled trapezoidal cutouts, and the right-angled trapezoidal cutouts form the shoe last inversion groove of the frame.

[0008] As a limitation of this utility model, the middle of both sides of the frame can be detachably provided with trays for placing the inner bottom.

[0009] As a further limitation of this utility model, one of the trays is engraved with the character "left" and the other tray is engraved with the character "right".

[0010] As another limitation of this utility model, the bottom of the frame is detachably provided with a storage basket for storing pneumatic nail guns and nails.

[0011] As a further limitation of this utility model, it also includes a lifting platform for placing the frame;

[0012] The lifting platform includes a top plate, a base frame, and multiple telescopic rods connecting the top plate and the base frame.

[0013] As a further limitation of this utility model, the bottom of one side of the base frame is provided with two traveling wheels, and the bottom of the other side is provided with two support legs.

[0014] As a further limitation of this utility model, a handle is provided on one side of the top plate; the handle and the support leg are located on the same side.

[0015] By adopting the above-mentioned technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows:

[0016] (1) This utility model utilizes a dividing rod to construct two right-angled trapezoidal cutouts on the top of the frame to accommodate shoe lasts, allowing the shoe lasts to be placed upside down on the frame, thus facilitating workers to perform the "shoe last nailing" operation. When using this utility model, there is no need to calibrate the shoe last position multiple times, and the shoe last can be placed upside down on the frame quickly and accurately; in addition, the posture of each shoe last on the frame is the same (the forefoot part of the shoe last faces the bottom edge of the right-angled trapezoidal cutout, and the heel part of the shoe last faces the top edge of the right-angled trapezoidal cutout), enabling workers to quickly and accurately place the insole on the bottom surface of the shoe last.

[0017] Compared to the existing technology that uses pillars to temporarily fix the shoe last, this utility model reduces the time workers spend adjusting and correcting the position of the shoe last, effectively improving the work efficiency of "nailing the insole".

[0018] (2) This utility model has trays on both sides of the frame for storing the insoles. When nailing the insoles, the insoles can be picked up and used at will, which is convenient for workers. In addition, the words "left" and "right" are engraved on the two trays respectively, which can remind workers whether the insoles of the left foot or the right foot are placed in the tray.

[0019] (3) The lifting platform equipped in this utility model can position the frame at a suitable height so that workers can perform the "nailing the inner bottom" work in a comfortable posture.

[0020] In summary, this utility model has a reasonable structure and is easy to use. It is suitable for use when "nailing the insole" to temporarily fix the shoe last in an inverted state. Attached Figure Description
