Description
Technical Field
The invention relates to the technical field of waste shoe material classification and recovery, in particular to a disassembling device for a waste shoe material cutting sole.
Background
With the improvement of living of materials, people have higher and higher requirements for shoes, and along with this, recycling shoe materials has become a problem of important attention, and recycling of waste shoe materials has become a hot point of discussion.
For recycled shoe materials, the global famous sports brands adidas, nike and the like are also very concerned in relevant aspects. For example, CN202010081297.4 discloses a sports shoe, which comprises an upper and a sole made of the same thermoplastic matrix material, the proportion of which is more than 95% at the most. For example CN201980032639.9 discloses an article of footwear, a manufacturing device and process for forming footwear using recycled plastic, mainly by recycling thermoplastic elastomers or EVA, grinding it and forming the sole by adding a foaming agent activated at high temperature and placing in a final mould.
Therefore, the application of recyclable materials to shoe materials is very important for the global famous sports brands, and although certain technical foundation exists in China, the recyclable materials all have technical defects of different degrees.
In the aspect of a specific method for recycling waste shoe materials, the waste shoe materials are recycled by commonly utilizing a crushing mode in the prior art. For example, CN201810207978.3 discloses a device for disassembling used shoes and recycling useful materials thereof, which uses a multi-stage crushing mechanism and a screening and separating module composed of a blower to separate and recycle the used shoes with different qualities in a cavity. However, the processing device still cannot realize the efficient separation of the sole from the vamp in the crushed material.
Further, the prior art also provides for the recovery of waste shoe material by heating the sole. For example, CN201910928622.3 discloses a sole waste recycling device, which heats the sole by introducing high-temperature steam into the cavity of the iron column inserted into the sole, thereby reducing the pulling force required for separating the upper and the sole. However, the peeling force of the upper of the device is basically vertical to the sole, and the power consumption is larger.
Further, the prior art also provides a method for separating and recycling the sole and the vamp by cutting. For example, CN202010982729.9 discloses an environment-friendly and efficient waste shoe recycling device, which cuts waste shoes on a fixed conveyor belt through cutting devices arranged on two sides of the conveyor belt, and then realizes the separation of a sole and a vamp under the material stirring effect of a material stirring device. Because the sole height is not unique, need frequently adjust the position of cutting device in the in-service use process, production efficiency is lower.
In summary, there is a need for a high-efficiency disassembling device for separating shoe sole and shoe upper.
