Description
Technical Field
[0001] The utility model relates to the technical field of shoe production, in particular to a shoe last removal mechanism. Background Art
[0002] The shoe last, also known as the shoe last, is a traditional shoemaking tool that is shaped like a human foot and is used to fill the shoe so that it fits the foot. It is an important part of the shoemaking process and affects the appearance and comfort of the shoe. During the shoemaking process, the shoe last is used to support and shape the leather shoes to ensure that the shoes maintain the correct shape and structure during the manufacturing process. When the shoe is finished, the shoe last needs to be removed from the inside of the shoe. This process is called stripping.
[0003] The traditional mechanism of stripping lasts is divided into three parts, as follows:
[0004] Last: used to insert into the shoe for support and shaping;
[0005] Positioning rod: inserted into the hole on the last, plays a basic positioning role for the last during the last removal process;
[0006] Ejection mechanism: It is usually driven by a driving mechanism to push a force-applying component, which is usually a ejection frame or an ejection block. During the pushing process, the component contacts the outer heel of the shoe and continues to push. Due to the basic limit obtained by the insertion of the rod into the socket, the shoe can be removed from the last.
[0007] The inner size of the hole on the last will be slightly larger than the outer size of the positioning rod, and the last will shake to a certain extent. At this time, the staff needs to apply a certain amount of pressure to the shoes to ensure the stability and smoothness of the last removal process.
[0008] In the process of implementing the solution, the inventors found that the following problems in the prior art have not been well solved: since the work of removing the last is not a small amount of work, but a large-scale, long-term work, manually applying a certain pressure cannot maintain stability for a long time, and it is easy to cause hand fatigue from long-term work, which leads to failure of removing the last after the force is biased, and it is necessary to push the material again after the pushing mechanism moves back. In addition, different positions of the shoes are bonded with glue, and the glue has not been completely solidified within a certain period of time. The tilting of the force-applying component can easily lead to debonding at the bonding point after it has not solidified, which not only causes physical burden on the staff, but also leads to reduced work efficiency and the need to rework after debonding at the bonding point. Utility Model Content
[0009] The main purpose of the utility model is to provide a shoe last removal mechanism, which can effectively solve the problems in the background technology.
[0010] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0011] The last-removing mechanism includes a base column and a shoe last, a positioning rod is fixed on the top of the base column, a limiting hole is drilled on the side wall of the positioning rod away from one end of the base column, a rod groove is drilled on the position of the positioning rod of the shoe last, an operating groove is drilled on the end of the shoe last located near the outside of the rod groove, a sliding groove is drilled on the end of the shoe last located at the operating groove away from the base column, a pushing block is inserted and slidably inserted in the operating groove, an insert block is slidably connected to the end of the sliding groove close to the rod groove, a spring 2 is fixed on the end of the sliding groove away from the insert block, and an inclined groove is drilled on the end of the insert block close to the pushing block.
[0012] Preferably, the operating groove is communicated with the sliding groove, and the operating groove is communicated with the rod groove.

[0014] Preferably, the end of the second spring close to the insert block is fixedly connected, the end of the insert block away from the second spring is inserted into the inside of the limiting hole, and the outer size of the insert block matches the inner size of the limiting hole.
[0015] Preferably, a reset groove is bored on one end of the shoe last located inside the operating groove near the bottom column, a reset plate is fixed to the outer wall of the pushing block located inside the reset groove, a spring 1 is embedded in the reset groove at one end of the reset plate near the plug-in block, one end of the spring 1 is in contact with one side of the reset groove near the plug-in block, and the other end of the spring 1 is in contact with one end of the reset plate near the reset plate.
[0016] Preferably, a pad is fixed to the outer wall of the positioning rod at the rod groove position, and the pad is in contact with the end of the shoe last that is close to the shoe last.
[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0027] Specifically, the operating groove 42 is communicated with the sliding groove 43 , and the operating groove 42 is communicated with the rod groove 41 .
[0028] Specifically, one end of the pushing block 5 close to the inserting block 53 is inserted into the inside of the inclined groove 54, and the one end of the pushing block 5 close to the inclined groove 54 is an inclined surface, and this end contacts the inclined surface of the inclined groove 54, and the squeezing of the inclined surface can make the inserting block 53 move back.
[0029] Specifically, the end of the spring 2 6 close to the insert block 53 is fixedly connected, and the end of the insert block 53 away from the spring 2 6 is inserted into the inside of the limiting hole 21, and the outer size of the insert block 53 matches the inner size of the limiting hole 21.
[0030] Specifically, a reset groove 44 is bored at one end of the shoe last 4 located inside the operating groove 42 near the bottom column 1, a reset plate 51 is fixed to the outer wall of the pushing block 5 located inside the reset groove 44, a spring 52 is embedded in the reset groove 44 at one end of the reset plate 51 near the plug block 53, one end of the spring 52 is in contact with one side of the reset groove 44 near the plug block 53, and the other end of the spring 52 is in contact with one end of the reset plate 51 near the reset plate 51, the tension of the spring 52 can push the reset plate 51, so that one end of the pushing block 5 can not generate too much squeezing force on the inclined groove 54, so that the plug block 53 can be stably pushed into the inside of the limiting hole 21 through the spring 2 6, and when the pushing block 5 is pressed to drive the plug block 53 to move back and complete the last removal work, the pushing block 5 can move back through the spring 1 52 to avoid causing greater pressure on the plug block 53.
