[0032] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] It can be understood that the terms "first", "second", etc. used in the present application can be used in this article to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish the first element from another element.

[0034] like Figure 1 , Figure 2 , Figure 7 , Figure 8 and Fig. 9 As shown, in one embodiment, a plastic packaging bag recycling and processing device is proposed, the device comprising:

[0035] The main body barrel 1 comprises a mounting barrel body 101 arranged on the main body barrel 1, a fixing platform 102 is fixedly installed on the surface of the mounting barrel body 101, a feed port 103 is opened on the surface of the mounting barrel body 101, and a conical discharge port 104 is slidably connected to the inner wall of the mounting barrel body 101;

[0036] The scraping mechanism 2 comprises eight V-shaped scrapers 201 installed inside the mounting barrel 101, the surface of each V-shaped scraper 201 is rotatably connected to a sliding rod 202, the surface of the sliding rod 202 is slidably connected to a sleeve rod 204, a tension spring 203 is fixedly installed on one end of the sliding rod 202 away from the V-shaped scraper 201, one end of the tension spring 203 away from the sliding rod 202 is connected to the inner wall of the sleeve rod 204, and the inner wall of the V-shaped scraper 201 contacts the surface of the cutting blade 205;

[0037] Slide mechanism 3: used to drive the V-shaped scraper 201 to move in contact with the surface of the cutting blade 205;

[0038] Driving mechanism 6: used to drive the cutting blade 205 to rotate and cut the plastic bag.

[0039] In practical application of the embodiment of the present invention, when performing a plastic bag cutting operation, such as Figure 1 As shown, after the plastic bag is put into the installation cylinder body 101 from the feed port 103, the driving mechanism 6 drives the cutting blade 205 to rotate to cut the plastic bag. When the cutting reaches the set time, as shown in FIG. Figure 2 As shown, from Figure 2 From the front view direction, at this time, the four cutting blades 205 at the bottom and the four cutting blades 205 at the top move towards each other under the action of the slide mechanism 3, so as to achieve automatic switching of the cutting blade 205 for cyclic cutting, to avoid the problem that the cutting edge of the cutting blade 205 is overheated and the plastic bag is adhered to it, affecting the cutting effect, and at the same time, the cutting blade 205 at the bottom is cooled, and at the same time, under the action of the slide mechanism 3, the V-shaped scraper 201 is driven to move along the surface of the cutting blade 205. Since the V-shaped scraper 201 and the cutting edge of the cutting blade 205 are in contact with each other, the plastic bag melted and adhered on the cutting edge of the cutting blade 205 is pushed off. At the same time, since the cutting edge cross section of the cutting blade 205 is twisted, as shown in FIG. Figure 7 As shown, through the action of the sliding rod 202 and the tension spring 203, the V-shaped scraper 201 always changes its posture synchronously with the cutting edge of the cutting blade 205 during the movement, thereby effectively scraping off the plastic bag adhering to the cutting edge of the cutting blade 205, and in conjunction with the driving action of the driving mechanism 6, the plastic bag pushed off the cutting edge of the cutting blade 205 is thrown out under the action of centrifugal force, thereby realizing the function of quickly cleaning the cutting edge of the cutting blade 205.

[0040] like Figure 3 , Figure 4 and Figure 6 As shown, as a preferred embodiment of the present invention, the slide mechanism 3 includes a slide rod 301 fixedly connected to the sleeve rod 204, and the end of the slide rod 301 away from the sleeve rod 204 is slidably connected to the first smooth groove 302, and the first smooth groove 302 is opened inside the slide column 306, and the interior of the slide column 306 is also provided with a first inclined groove 303, a second inclined groove 304 and a second smooth groove 305 connected in sequence.

[0041] In actual application of the embodiment of the present invention, during the process of switching the cutting blade 205, as shown in FIG. Figure 6 As shown, the slide rod 301 slides in the first smooth groove 302. Figure 3 and Figure 4As shown, at this time, the slide rod 301 slides along the first smooth groove 302 to the first inclined groove 303. Since the first inclined groove 303 is away from the central axis of the slide column 306, the V-shaped scraper 201 is driven by the slide rod 301 to move along the cutting edge of the cutting blade 205, and the plastic bag stuck on the cutting edge of the cutting blade 205 is pushed off and thrown out in cooperation with the rotational centrifugal force generated by the driving mechanism 6. When it runs to the second inclined groove 304, the slide rod 301 drives the V-shaped scraper 201 to reset. After moving to the second smooth groove 305, the V-shaped scraper 201 is retracted into the device. When the cutting blade 205 above moves downward synchronously, this operation process is repeated, so that the cutting edge of the cooled cutting blade 205 is cleaned again to ensure that there is no sticky plastic bag on its surface.

Fig.10 and Fig.11 As shown, from Fig.11 When viewed from the front, the curved gear 404 starts to rotate, and the rotation of the curved gear 404 drives the first curved rack 401 to move obliquely upward to the right, and simultaneously drives the second curved rack 405 to move obliquely downward to the left, and then drives the upper and lower cutting blades 205 to exchange positions through the sliding block 403, thereby completing the switching of the cutting blades 205.

[0044] like Fig.10 and Fig.11 As shown, as another preferred embodiment of the present invention, the device also includes a rotating mechanism 5, the rotating mechanism 5 includes a linkage bevel gear 501 coaxially fixedly connected to the curved gear 404, the linkage bevel gear 501 passes through the slide column 306 and is rotatably connected to the slide column 306, the linkage bevel gear 501 is meshed with the main bevel gear disc 502, and the main bevel gear disc 502 is fixedly connected to the output end of the rotating motor 503.

Fig.10 and Fig.11 As shown, at this time, the rotating motor 503 starts to run, and the operation of the rotating motor 503 drives the main bevel gear 502 to rotate, thereby driving the linkage bevel gear 501 to rotate, and the rotation of the linkage bevel gear 501 drives the curved gear 404 to rotate synchronously, thereby driving the cutting blade 205 to switch positions through the switching mechanism 4.

[0046] like Figure 5 As shown, as another preferred embodiment of the present invention, the driving mechanism 6 includes a driving motor 604 fixedly mounted on the fixed table 102, and a driving bevel gear 603 is fixedly mounted on the output end of the driving motor 604, and the driving bevel gear 603 is meshed with the bevel gear ring 602, and the bevel gear ring 602 is coaxially fixedly mounted on the surface of the main rotating shaft 601, and a sliding block 403 is slidably mounted on the main rotating shaft 601, and the first curved rack 401 and the second curved rack 405 are both slidably connected to the inner wall of the main rotating shaft 601, and a rotating motor 503 is fixedly mounted on the inner wall of the main rotating shaft 601, and the output end of the rotating motor 503 passes through the inner wall of the main rotating shaft 601 and is rotatably connected to the main rotating shaft 601, and eight straight slots are opened on the main rotating shaft 601, and the connecting tube 402 is slidably connected to the straight slots on the main rotating shaft 601.

[0049] In practical application of the embodiment of the present invention, when switching the cutting blade 205, as shown in FIG. Figure 3 and Fig.10 As shown, at this time, the movement of the connecting tube 402 drives the closing cloth strip 701 to stretch, sealing the straight slot on the main rotating shaft 601, thereby preventing the plastic bag from entering the interior of the device through the straight slot of the main rotating shaft 601 during the cutting process and affecting the movement of the device.

[0050] like Figure 7 As shown, as another preferred embodiment of the present invention, the surface of the V-shaped scraper 201 is provided with a hard anti-sticking layer.
