Description

Technical Field

[0001] The utility model relates to the technical field of BOPP heat-sealing film preparation, in particular to a high-efficiency and uniform mixing mechanism and ultra-low temperature BOPP heat-sealing film preparation equipment. Background Art

[0002] BOPP heat-sealing film is a basic type of BOPP film, mainly used for printing, composite bag making or wrapping packaging. During its production and processing, it is often necessary to use a special mixing mechanism to mix its raw materials to ensure the production quality of subsequent ultra-low temperature BOPP heat-sealing film preparation equipment and improve the production efficiency of BOPP heat-sealing film.

[0003] According to a raw material mixing device for producing ultra-low temperature heat-sealing film disclosed on the patent website (authorization announcement number: CN212421839U), "a raw material mixing device for producing ultra-low temperature heat-sealing film, relating to the field of plastic film production equipment, is proposed to solve the existing problem of uneven mixing. It includes a mixing box, one side of the mixing box is fixedly connected to a motor by bolts, and the output end of the motor is fixedly connected to a rotating shaft rotatably connected to the mixing box through a coupling, the outer wall of the rotating shaft is fixedly sleeved with a connecting sleeve, and the outer wall of the connecting sleeve is fixedly welded with multiple stirring plates, one of the stirring plates is fixedly connected to a micro-mixing device, and the inner wall of the mixing box is fixedly connected to multiple blocking bars, one side of the mixing box is fixedly connected to a circulation pipe, and the lower side of the circulation pipe is fixedly connected to a guide pipe", "the structure is simple and easy to use, so that the overall flow direction is chaotic, the mixing efficiency is accelerated, and at the same time, it is rotated by the micro-motion rod and the rotating frame to reduce the combination of small pieces and ensure the quality of mixing."

[0004] In view of the above description, the applicant believes that the following problems exist:

[0005] During use, the existing device can disrupt the overall flow direction, speed up the mixing efficiency, and reduce the combination of small pieces by coordinating the use of multiple sets of stirring plates, micro-mixing devices and blocking strips. However, in actual applications, when the device stirs the raw materials, the raw materials are likely to penetrate into the guide tube and the circulation tube, resulting in the problem that the micro-mixing device is difficult to perform related mixing work. In addition, since the rotation direction of the multiple sets of stirring plates is relatively fixed, it is difficult to produce a large flow disorder, resulting in the problem of inefficient mixing. In addition, after the existing ultra-low temperature hot BOPP heat sealing film preparation equipment completes the production of BOPP heat sealing film, it is easy to cause wrinkles on the surface of the film due to the direct discharge and storage work, which affects subsequent use. Therefore, we urgently need an efficient and uniform mixing mechanism and ultra-low temperature hot BOPP heat sealing film preparation equipment to solve the above problems. Utility Model Content
