Description

Technical Field

[0001] The present application relates to the technical field of crushing devices, and in particular to a recycled plastic bag crushing device. Background Art

[0002] Crushing plastic bags into small particles or fragments before recycling can significantly improve the efficiency of subsequent recycling processes. Small particles or fragments are easier to clean, melt, and perform other recycling steps, thus speeding up the entire recycling process. Crushed plastic bags are significantly smaller, making them easier to transport, store, and handle. This not only saves space but also reduces processing costs. Crushing removes impurities and contaminants from the plastic bags, increasing the purity of the recycled plastic particles. Pure recycled plastic particles can be processed into higher-quality plastic products. Crushing and recycling plastic bags is a key means of achieving resource recycling. Recycling and reusing used plastic bags can reduce reliance on virgin plastic, reduce resource consumption, and reduce environmental pollution.

The crushed plastic bags fall from the bottom of the crushing rollers for subsequent unified collection. In the process of crushing by the crushing rollers, plastic woven bags with harder materials need to be crushed together. Because there is an annular groove inside the crushing roller, the crushed plastic woven bag fragments will be stuck in the annular groove of the crushing roller, which will cause blockage if accumulated for a long time.

[0025] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0026] The following is combined with Figure 1-4 The embodiments of the present application are described in further detail.

[0027] Example 1

[0028] See also Figures 1-4 , this embodiment provides a technical solution: a recycled plastic bag crushing device, comprising: a main frame 1, a crushing mechanism 2 and a cleaning mechanism 3;

[0029] Horizontal circular holes are provided on both sides of the interior of the main frame 1. The circular holes provided on the main frame 1 can provide the internal structure with stable rotation, and the top of the main frame 1 provides a feed port for plastic, and the bottom of the main frame 1 provides a discharge port for the crushed plastic. The crushing mechanism 2 is arranged inside the main frame 1, and the crushing mechanism 2 can crush the plastic by rotating. The driving motor 201 is fixed on the outer wall of the main frame 1, and the driving motor 201 can provide a stable rotation connection for the structure connected on the output end. The crushing roller 202 is connected to the output end of the driving motor 201, and the crushing roller 202 can crush the plastic placed above during the rotation. The crushing roller 202 is arranged inside the main frame 1, and the crushing roller 202 can quickly crush the plastic placed inside the main frame 1.

[0030] The cleaning mechanism 3 is arranged on the main frame 1, and the cleaning mechanism 3 can clean the plastic fragments attached to the surface of the crushing roller 202. The cleaning mechanism 3 includes a connecting shaft 301 that is rotatably connected inside the circular hole of the main frame 1. The connecting shaft 301 can drive the structure on the shaft to change the angle synchronously after the angle changes. The scrapers 302 are equidistantly welded on the connecting shaft 301. The scrapers 302 can change the angle so as to fit under the outer wall of the crushing roller 202. During the rotation of the crushing roller 202, the plastic fragments on the surface of the crushing roller 202 are cleaned. A connecting rod 303 is welded on one end of the connecting shaft 301 located on the outside of the main frame 1. When the connecting rod 303 is pulled, it can drive the connected connecting shaft 301 to rotate.

[0031] Block No. 1 305 is welded on the connecting rod 303, and the cross-section of block No. 1 305 is in the shape of a "U". Block No. 2 306 is arranged above block No. 1 305. The cavity inside block No. 2 306 can place and fix the internal structure. Block No. 2 306 is welded on the outer wall of the main frame 1, which can serve as a stable connection between the structures. A through hole is provided on block No. 2 306, which can provide the internal structure of block No. 2 306 for installation and removal from the reserved through hole. The two ends are respectively covered with elastic bands 307 on block No. 1 305 and block No. 2 306. The elastic band 307 can drive one end of the connecting rod 303 to change its position through its own elastic force.

[0032] Place the plastic into the inside of the main frame 1, start the drive motor 201, and the drive motor 201 will drive the crushing roller 202 to rotate. The rotation of the crushing roller 202 will drive the plastic to be crushed. When there are plastic fragments attached to the surface of the crushing roller 202, because the connecting shaft 301 is connected to the No. 1 block 305 through the connecting rod 303, and the No. 1 block 305 is connected to the No. 2 block 306 through the elastic belt 307, the elastic force of the elastic belt 307 itself will pull the connecting shaft 301 inside the main frame 1 to change its angle, so that the scraper 302 on the connecting shaft 301 is attached to the surface of the crushing roller 202. During the rotation of the crushing roller 202, the plastic fragments on the surface are separated from the surface of the crushing roller 202 during the contact with the scraper 302, and are thus cleaned.

[0033] Example 2

[0034] See also Figures 1-4 , this embodiment provides a technical solution: a recycled plastic bag crushing device, including: a baffle 304, a rotating shaft 308, a limit block 309 and a groove 310;

[0035] The baffle 304 is arranged above the connecting rod 303, and the baffle 304 can limit the angle change of the connecting rod 303, thereby preventing the scraper 302 from being too close to the surface of the crushing roller 202, and the baffle 304 is welded to the outer wall of the main frame 1, which can play an effective structural connection. The rotating shaft 308 is horizontally welded above the through hole of the No. 2 block 306, and the rotating shaft 308 can provide the structure on the shaft with an angle change, thereby rotating.

[0036] The limit block 309 is rotatably connected to the rotating shaft 308, and the limit block 309 can limit the elastic band 307 inside the No. 2 block 306 to prevent the elastic band 307 from falling off from the hole opened in the No. 2 block 306, and the other end of the limit block 309 is provided with anti-slip grooves, which can be more stable in the subsequent clamping and fixing process. The groove 310 is set below the through hole of the No. 2 block 306, and the groove 310 can limit and fix the internal structure, and the other end of the limit block 309 is set inside the groove 310. The anti-slip grooves on the outer surface of the limit block 309 are in friction contact with the inner wall of the groove 310, thereby achieving rapid clamping and fixing.

[0037] After the connecting shaft 301 is pulled by the elastic band 307 and its angle changes, the baffle 304 limits the top end of the connecting rod 303, thereby providing a limit for the angle change of the connecting shaft 301, preventing the scraper 302 from being too close to the crushing roller 202 and affecting its rotation. When it is necessary to clean the plastic fragments on the surface of the scraper 302, the limit block 309 on the rotating shaft 308 is rotated. At this time, the limit block 309 no longer continues to be engaged in the inside of the groove 310, so that one end of the elastic band 307 can be removed from the inside of the No. 2 block 306. At this time, the scraper 302 can be rotated to a vertical state through the connecting shaft 301, which is convenient for personnel to clean from the bottom of the main frame 1.

[0038] The implementation principle of the recycled plastic bag crushing device of the present application is as follows:

[0039] First, place the plastic into the main frame 1 and start the drive motor 201. The drive motor 201 will drive the crushing roller 202 to rotate, and the rotation of the crushing roller 202 will drive the plastic to be crushed. When there are plastic fragments attached to the surface of the crushing roller 202, because the connecting shaft 301 is connected to the No. 1 block 305 through the connecting rod 303, and the No. 1 block 305 is connected to the No. 2 block 306 through the elastic belt 307, the elastic force of the elastic belt 307 itself will pull the connecting shaft 301 inside the main frame 1 to change its angle, so that the scraper 302 on the connecting shaft 301 is attached to the surface of the crushing roller 202. During the rotation of the crushing roller 202, the plastic fragments on the surface are separated from the surface of the crushing roller 202 during the contact with the scraper 302, and are thus cleaned.

[0040] Secondly, after the angle of the connecting shaft 301 changes due to the traction of the elastic band 307, the baffle 304 limits the top of the connecting rod 303, thereby limiting the angle change of the connecting shaft 301 and preventing the scraper 302 from being too close to the crushing roller 202 and affecting its rotation.

[0041] Finally, when it is necessary to clean the plastic fragments on the surface of the scraper 302, by rotating the limit block 309 on the rotating shaft 308, the limit block 309 will no longer continue to be engaged in the inside of the groove 310, so that one end of the elastic band 307 can be removed from the inside of the No. 2 block 306. At this time, the scraper 302 can be rotated to a vertical state through the connecting shaft 301, which is convenient for personnel to clean from the bottom of the main frame 1.

[0042] It will be apparent to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present application is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.
