Description

Technical Field

[0001] This utility model relates to the field of plastic woven bag technology, specifically a device for re-granulating and recycling recycled plastic woven bags. Background Technology

[0002] Plastic woven bag re-granulation and recycling equipment is mainly used to recycle waste and discarded plastic woven bags. Through processes such as crushing, granulation, and melting, it transforms them into reusable plastic pellets. This process realizes the recycling of waste plastics, which not only helps reduce environmental pollution but also saves resources and reduces production costs. It is an important piece of equipment in the fields of environmental protection and resource recycling.

[0003] In existing technologies, single-stage crushing and granulation are widely used for the recycling and granulation of composite materials such as woven bags. However, this method is not effective enough when dealing with the interwoven fibers, multi-layered structure, and composite characteristics of different materials in woven bags. Single-stage crushing and granulation often fails to completely break down the complex structure of woven bags, resulting in unsatisfactory crushing and granulation effects and uneven material size, which poses challenges to subsequent sorting, cleaning, and reprocessing stages. To address this, we propose a recycling and granulation device for recycled plastic woven bags. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0033] Example 1

[0034] like Figure 1-4As shown, in this embodiment, a recycled plastic woven bag granulation and recycling device includes: a box 1, a crushing component 4 and a screening component 5. An extruder 2 is fixedly connected to one side of the box 1. A cooling mechanism 3 is provided inside the extruder 2, which can perform extrusion granulation. The woven bag is melted and extruded through the extruder 2. During the extrusion process, it is cooled and hardened by the cooling mechanism 3. The extruder 2 and the cooling mechanism 3 are existing technologies and will not be described in detail.

[0035] The crushing assembly 4 includes: a first motor 41, a rotating drum 42, a drive box 43, a second motor 44, and a crushing roller 45. The first motor 41 is fixedly connected to the outside of the housing 1. The rotating drum 42 is rotatably connected inside the housing 1. The drive end of the first motor 41 extends into the housing 1 and is fixedly connected to one end of the rotating drum 42. Multiple crushing rods 421 are fixedly connected inside the rotating drum 42, and the multiple crushing rods 421 are arranged around the central axis of the rotating drum 42. The two drive boxes 43 are respectively fixedly connected to both sides of the housing 1, and the two drive boxes 43 are separated by a... The device has a funnel-shaped configuration with openings on the outer sides of both drive boxes 43. Two second motors 44 are fixedly connected inside the two drive boxes 43, and drive wheels 441 are fixedly connected to the drive ends of both second motors 44. Belts 442 are sleeved around the two drive wheels 441. Two crushing rollers 45 are rotatably connected inside the two drive boxes 43, and driven wheels 443 are fixedly sleeved on one side of each crushing roller 45. One end of each belt 442 is sleeved around the two driven wheels 443. Granulation is achieved through crushing.

[0036] In this embodiment, it should be noted that the wrap angle of the belt 442 is between 120 degrees and 180 degrees. There are meshing teeth between the belt 442, the drive wheel 441, and the driven wheel 443 to ensure transmission efficiency. The toothed belt 442, the drive wheel 441, and the driven wheel 443 form a synchronous pulley group. This is the prior art and will not be described in detail.

[0037] In practice, the first motor 41 is started, which drives the drum 42 to rotate, thereby driving multiple crushing rods 421 to rotate, and performing preliminary crushing and granulation on the extruded strip material. At the same time, two second motors 44 are started, which drive two drive wheels 441 to rotate, thereby driving two belts 442 to rotate. The two belts 442 drive two corresponding driven wheels 443 to rotate, that is, drive two crushing rollers 45 to rotate relative to each other, and perform secondary crushing and granulation on the material. After secondary crushing, the crushing effect is better, which facilitates subsequent sorting, cleaning and reprocessing.

[0038] Example 2

[0039] Based on Example 1, a screening component 5 is provided for screening materials.

[0040] like Figure 1-4 As shown, in this embodiment, the screening component 5 includes: a collection box 51, a frame 52, and a third motor 53. The collection box 51 is fixedly connected to the bottom of the box body 1, and a screen 511 is fixedly connected to the top of the collection box 51. The frame 52 is fixedly connected inside the box body 1 and is located at the top of the collection box 51. A screening box 521 is slidably connected inside the frame 52, and one end of the screening box 521 extends out of the box body 1. The third motor 53 is fixedly connected to the outside of the box body 1. A rotating wheel 531 is fixedly connected to the drive end of the third motor 53. A connecting rod 532 is rotatably connected to one side of the rotating wheel 531. A push rod 533 is rotatably connected to one end of the connecting rod 532. The push rod 533 is fixedly connected to the outer end of the screening box 521. It should be noted that the screening box 521 will not completely slide out of the frame 52 during operation.

[0041] In this embodiment, the aperture of the screen 511 is smaller than that of the sieve box 521, which can separate the material into different specifications. One end of the sieve box 521 is closed, and the other end is detachable. The closed end can prevent the material from falling out of the device, and the detachable end makes it convenient to remove the material and to clean and replace parts.

[0042] In practice, the crushed and granulated material falls onto the screening box 521. At the same time, the third motor 53 is started, which drives the rotating wheel 531 to rotate. This, in turn, drives the connecting rod 532 and the push rod 533 to make continuous linear reciprocating motion, which causes the screening box 521 to move back and forth within the frame 52 to screen the material. The material is then screened again through the screen 511, and the screened particles are collected through the collection box 51.

[0043] Working principle: First, the woven bag is melted and extruded through extruder 2. During the extrusion process, it is cooled and hardened by cooling mechanism 3. At the same time, the first motor 41 is started, which drives the drum 42 to rotate, thereby driving multiple crushing rods 421 to rotate, performing preliminary crushing and granulation on the extruded strip material. Simultaneously, two second motors 44 are started, which drive two drive wheels 441 to rotate, thereby driving two belts 442 to rotate. The two belts 442 drive two corresponding driven wheels 443 to rotate, thereby driving two crushing rollers 45 to rotate relative to each other, performing secondary crushing and granulation on the material. The crushed and granulated material falls onto the screening box 521. At the same time, the third motor 53 is started, which drives the rotating wheel 531 to rotate, thereby driving the connecting rod 532 and push rod 533 to perform continuous linear reciprocating motion, thereby driving the screening box 521 to move back and forth within the frame 52 to screen the material. Then, it is screened again through screen 511. The screened particles are collected through collection box 51.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
