Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, specifically a mixing device for polyvinyl chloride particle raw materials. Background Technology

[0002] Polyvinyl chloride (PVC) is a polymer material in which one hydrogen atom in polyethylene is replaced by one chlorine atom. It is an amorphous polymer containing a small amount of crystalline structure. It is a polymer formed by the polymerization of vinyl chloride monomers under the action of initiators such as peroxides and azo compounds, or under the action of light and heat, according to the free radical polymerization mechanism. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins.

[0003] To improve the quality of polyvinyl chloride (PVC) products and meet the requirements of the production process, it is necessary to accurately weigh the PVC resin and additives according to the predetermined formula and disperse and mix them to ensure that the additives and other components are uniformly dispersed in the PVC. Therefore, the mixing equipment and process conditions for PVC granules are very important.

[0004] Existing mixing equipment for polyvinyl chloride (PVC) particles typically uses a rotating stirring rod or blade inside the mixing tank to agitate the raw materials. This method means that the PVC particles in the mixing tank only receive the rotational stirring force, resulting in a relatively uniform stirring force and a similar stirring trajectory. Consequently, the mixing efficiency of the PVC particles is low. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] Please see Figure 1-4 This utility model provides a new technical solution: a mixing device for polyvinyl chloride particle raw materials, including a mixing tank 1, which is hollow inside;

[0043] The mixing tank 1 is equipped with a cover 2;

[0044] Among them, a motor 3 is fixedly connected to the upper surface of the mixing tank 1, and the rotation output shaft of the motor 3 rotates through the mixing tank 1.

[0045] Among them, the rotating output shaft of the mixing tank 1 is fixedly connected to the rotating rod 5;

[0046] The rotating rod 5 is equipped with a mixing mechanism, which includes a fixed ring 6, a sliding block 11, a connecting block 7, a feed port 4, a sliding protrusion 8, a connecting rod 9, a sliding ball 10, an inner sliding groove 12, a connecting groove 13, a fixed block 14, a mixing rod 15, and a spring 16.

[0047] Furthermore, the retaining ring 6 is fixedly connected to the lower surface of the cover 2;

[0048] Among them, the fixed ring 6 is slidably sleeved on the outer surface of the rotating rod 5;

[0049] Among them, multiple sliding protrusions 8 are fixedly connected to the lower surface of the fixed ring 6, and the multiple sliding protrusions 8 are arranged in a central array;

[0050] The connecting groove 13 is formed on the outer surface of the rotating rod 5.

[0051] Furthermore, the sliding block 11 is mounted on the rotating rod 5, and the inner groove 12 is formed inside the sliding block 11;

[0052] The lower end of the rotating rod 5 slides through the inner groove 12;

[0053] The connecting block 7 is fixedly connected to the inner wall of the inner slide groove 12, and the upper surface of the connecting block 7 extends through the upper surface of the sliding block 11.

[0054] Furthermore, the connecting block 7 is slidably connected to the connecting groove 13;

[0055] The connecting rod 9 is fixedly connected to the upper surface of the connecting block 7;

[0056] The sliding ball 10 is fixedly connected to the upper end of the connecting rod 9;

[0057] The sliding ball 10 is slidably connected to the sliding protrusion 8.

[0058] Furthermore, the fixing block 14 is slidably connected within the inner groove 12;

[0059] Among them, the connecting groove 13 extends downward from the lower surface of the rotating rod 5;

[0060] The upper surface of the fixed block 14 is fixedly connected to the lower surface of the rotating rod 5;

[0061] The spring 16 is fixedly connected to the bottom wall of the inner slide groove 12.

[0062] Furthermore, the upper end of the spring 16 is fixedly connected to the lower surface of the fixing block 14;

[0063] The feed inlet 4 is fixedly connected to the outer surface of the mixing tank 1, and the feed inlet 4 communicates with the interior of the mixing tank 1;

[0064] Among them, multiple mixing rods 15 are fixedly connected to the outer surface of the sliding block 11;

[0065] The lower surface of the sliding block 11 is spherical.

[0066] In the initial state, the spring 16 is compressed, so that under the action of the spring 16 release force, the lower surface of the connecting block 7 is pushed to contact the bottom wall of the mixing tank 1. At this time, the sliding ball 10 is in contact with the lowest end of the sliding protrusion 8, and the spring 16 is compressed so that the sliding ball 10 is always in contact with the sliding protrusion 8. In use, polyvinyl chloride particle raw material is poured into the mixing tank 1 through the feed port 4, and then the motor 3 is started. The motor 3 starts and drives the rotating rod 5 to rotate. The rotating rod 5 rotates and drives the sliding block 11 to rotate, and also drives multiple mixing rods 15 to rotate at the same time. Then the mixing rods 15 rotate to mix the polyvinyl chloride particle raw material in the mixing tank 1, and the mixing is uniform and the mixing efficiency is high.

[0067] Furthermore, when the motor 3 is started, as the motor 3 drives the sliding block 11 to rotate, it simultaneously drives the connecting block 7, connecting rod 9, and sliding ball 10 to rotate. During the rotation of the sliding ball 10, it slides along the outer surface of the sliding protrusions 8. During this process, under the action of the release force of the spring 16, the sliding ball 10 moves up and down along the trajectory of the lower surface of the sliding protrusions 8 while rotating. This, in turn, drives the connecting block 7, connecting rod 9, and sliding block 11 to move up and down simultaneously. This, in turn, drives the mixing rod 15 to move up and down simultaneously while rotating. This makes the movement trajectory of the mixing rod 15 more varied, so that the polyvinyl chloride particle raw material can also be stirred and mixed up and down during the rotation and mixing process. This makes the mixing rod 15 have a better mixing effect on the polyvinyl chloride particle raw material, thereby increasing the mixing efficiency of the mixing device for polyvinyl chloride particle raw material, thereby improving the production efficiency of polyvinyl chloride particles, and thus increasing the practicality of the mixing device.

[0068] Working principle: When the device is in use, in the initial state, the spring 16 is in a compressed state, so that under the action of the release force of the spring 16, the lower surface of the connecting block 7 is pushed to contact the bottom wall of the mixing tank 1. At this time, the sliding ball 10 is in contact with the lowest end of the sliding protrusion 8, and the compressed state of the spring 16 ensures that the sliding ball 10 is always in contact with the sliding protrusion 8. In use, polyvinyl chloride particle raw material is poured into the mixing tank 1 through the feed port 4, and then the motor 3 is started. The motor 3 drives the rotating rod 5 to rotate, and the rotating rod 5 drives the sliding block 11 to rotate, which also drives multiple mixing rods 15 to rotate simultaneously. Thus, the mixing rods 15 rotate to mix the polyvinyl chloride particle raw material in the mixing tank 1, resulting in uniform mixing and high mixing efficiency.

[0069] Furthermore, when the motor 3 is started, as the motor 3 drives the sliding block 11 to rotate, it simultaneously drives the connecting block 7, connecting rod 9, and sliding ball 10 to rotate. During the rotation of the sliding ball 10, it slides along the outer surface of the sliding protrusions 8. During this process, under the action of the release force of the spring 16, the sliding ball 10 moves up and down along the trajectory of the lower surface of the sliding protrusions 8 while rotating. This, in turn, drives the connecting block 7, connecting rod 9, and sliding block 11 to move up and down simultaneously. This, in turn, drives the mixing rod 15 to move up and down simultaneously while rotating. This makes the movement trajectory of the mixing rod 15 more varied, so that the polyvinyl chloride particle raw material can also be stirred and mixed up and down during the rotation and mixing process. This makes the mixing rod 15 have a better mixing effect on the polyvinyl chloride particle raw material, thereby increasing the mixing efficiency of the mixing device for polyvinyl chloride particle raw material, thereby improving the production efficiency of polyvinyl chloride particles, and thus increasing the practicality of the mixing device.
