Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to an auxiliary material addition mechanism for polypropylene production. Background Technology

[0002] Polypropylene is a widely used material. To give polypropylene specific functional properties, a small amount of auxiliary materials need to be added to ordinary polypropylene raw materials, then mixed in a mixer, and then re-granulated.

[0003] Currently, existing mixer equipment has a problem: it lacks an automatic auxiliary material addition function. In this case, manual operation is required to add the necessary auxiliary materials to the mixer's feed inlet. Therefore, it is essential to design an auxiliary material addition mechanism for polypropylene production. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an auxiliary material addition mechanism for polypropylene production.

[0005] The objective of this utility model can be achieved through the following technical solution: A material addition mechanism for polypropylene production includes a support arranged at the feeding port, an electric linear track vertically fixed on the support, a slide of the electric linear track and a vertical beam fixedly connected, a plurality of drive cylinders horizontally fixed on the vertical beam and distributed vertically, the piston rod end of the drive cylinder is connected to a rotary cylinder, and a positioning seat for positioning the material box is fixedly connected to the rotating table of the rotary cylinder.

[0006] The bracket is also fixed with a slide block, which is slidably connected to the guide rail. The guide rail is also fixedly connected to the base plate. Both ends of the guide rail are also equipped with limit blocks. The slide block is also threaded with locking screws.

[0007] The locking screw is a hand-tightening component.

[0008] The positioning seat has slots on both sides, and a limiting plate is fixed to one end of the positioning seat. A magnet is fixed to the limiting plate, and an iron sheet that cooperates with the magnet is fixed on the material box.

[0009] The limiting plate also has a connecting hole, and the material box has a pin that mates with the connecting hole.

[0010] Several protective covers are also fixed on the vertical beam.

[0011] The piston rod end of the drive cylinder is connected to the rotary cylinder via a connecting block, and a positioning seat is fixedly connected to the rotating table of the rotary cylinder via a connecting rod.

[0012] Compared with existing technologies, this auxiliary material addition mechanism for polypropylene production has the following advantages: In this invention, a material box containing auxiliary materials is placed on a positioning seat. An electric linear track can drive the vertical beam to move up and down, so that the corresponding positioning seat is located above the feeding port. Through the coordinated operation of the drive cylinder and the rotary cylinder, the auxiliary materials in the material box can be automatically added to the feeding port, making feeding very convenient.

[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] like Figures 1-4 As shown, the auxiliary material addition mechanism for polypropylene production includes a support 2 arranged at the feeding port 4. Specifically, a slide 11 is fixed on the support 2, and the slide 11 is slidably connected to the guide rail 12. The guide rail 12 is also fixedly connected to the base plate 1. Both ends of the guide rail 12 are also equipped with limit blocks 13. A locking screw 19 is threadedly connected to the slide 11. The locking screw 19 is a hand-tightening component. With this structure, when disassembling and assembling the material box 5, the locking screw 19 is loosened, so that the raw material feeding port 4 of the support 2 has enough space to facilitate the disassembly and assembly of the material box 5. An electric linear track 3 is vertically fixed on the support 2. The slide 3a of the electric linear track 3 is fixedly connected to the vertical beam 9. Multiple drive cylinders 10 are horizontally fixed on the vertical beam 9 and distributed vertically. The piston rod end of the drive cylinder 10 is connected to the rotary cylinder 8. A positioning seat 7 for positioning the material box 5 is fixedly connected to the rotating table of the rotary cylinder 8. The rotary cylinder 8 is an existing product, which can rotate 180 degrees each time.

[0016] The positioning base 7 has slots 7a on both sides, and a limiting plate 17 is fixed to one end of the positioning base 7. A magnet 16 is fixed on the limiting plate 17, and an iron piece 18 that cooperates with the magnet 16 is fixed on the material box 5. The limiting plate 17 also has a connecting hole 17a, and the material box 5 has a pin 5a that cooperates with the connecting hole 17a. With this structure, the material box 5 can be reliably fixed to the positioning base 7 through the cooperation of the slots 7a, the limiting plate 17, the magnet 16, the iron piece 18, the connecting hole 17a, and the pin 5a.

[0017] Multiple protective covers 6 are also fixed on the vertical beam 9. This structure can cover the upper part of the material box 5 on the positioning seat 7 to a certain extent.

[0018] The piston rod end of the drive cylinder 10 is connected to the rotary cylinder 8 via a connecting block 14, and a positioning seat 7 is fixedly connected to the rotating table of the rotary cylinder 8 via a connecting rod 15.

[0019] In this invention, the material box 5 containing auxiliary materials is placed on the positioning seat 7. The electric linear track 3 can drive the vertical beam 9 to move up and down, so that the corresponding positioning seat 7 is located on the side above the feeding port 4. Through the coordinated operation of the drive cylinder 10 and the rotary cylinder 8, the auxiliary materials in the material box 5 can be automatically added to the feeding port 4, making the feeding very convenient.

[0020] In this embodiment, when mixing once, 1 ton of ordinary polypropylene is added, and only one box of auxiliary material needs to be added. The weight of one box of auxiliary material is 200-400 grams. Only one box of auxiliary material needs to be added for each mixing operation.

[0021] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0022] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
