Description
Technical Field
[0001] This utility model relates to the field of PVC leather production technology, specifically to a PVC leather production mixing equipment. Background Technology
[0002] PVC leather is a type of artificial synthetic leather, also known as polyvinyl chloride leather. It is a leather-like material made by coating a layer of polyvinyl chloride resin (PVC) with additives such as plasticizers, stabilizers, and pigments onto a textile base fabric (such as polyester or cotton) or non-woven fabric, and then processing it through high-temperature plasticizing, embossing, and surface treatment.
[0003] In the production of PVC leather, mixing is a crucial step that directly affects the quality of the leather. Traditional mixing equipment often uses a unidirectional stirring structure, where materials move in only one direction within the cylinder, which can easily lead to stratification or mixing dead zones. This results in uneven dispersion of PVC resin with plasticizers, stabilizers, and other auxiliary materials, affecting the physical properties of the leather. Therefore, there is an urgent need for a new type of mixing equipment for PVC leather production. Utility Model Content

[0029] Through the above technical solution, the bracket 2 provides support for the entire mixing mechanism.

[0030] Example 2
[0031] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 Furthermore, based on Embodiment 1, the following is obtained: four movable wheels 13 are fixedly connected to the bottom of the base frame 1, and a push frame 14 is fixedly connected to the left side of the top of the base frame 1.

Two limiting holes are opened on the side plate 15, and a limiting rod 19 is slidably inserted into each limiting hole. The bottom of the limiting rod 19 is fixedly connected to the anti-slip plate 17.

After reaching the designated position, turn the limit mechanism 18 to make the lead screw 16 drive the anti-slip plate 17 to descend until the anti-slip plate 17 is in close contact with the ground to fix the device and prevent it from sliding during the mixing process. Then, power on the servo motor 5 to start it. The servo motor 5 drives the mixing shaft 6 to rotate. The first mixing rod 7 on the mixing shaft 6 mixes the material. At the same time, through gear transmission, the mixing drum 4 will also rotate in the opposite direction. The second mixing rod 8 on the inner wall of the mixing drum 4 cross-mixes with the first mixing rod 7 to make the material fully mixed. After the mixing is completed, open the valve on the discharge pipe to discharge the mixed material.
