[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, a raw material crushing equipment for a PET strapping tape production line comprises a crusher body 1; a sieve plate 11 is fixedly connected to the middle of the crusher body 1; a servo motor 12 is connected to the top of the crusher body 1; a first rotating shaft 13 is fixedly connected to the end of the servo motor 12; a plurality of groups of paddles 14 are fixedly connected to the middle of the first rotating shaft 13; a support plate 15 is fixedly connected to the middle of the first rotating shaft 13; the ends of the support plate 15 are all fixedly connected to a first scraper 16; a brush plate 17 is fixedly connected to the end of the first scraper 16; when working, the raw material to be crushed is first placed on the surface of the sieve plate 11, and then the servo motor 12 is operated to drive the first rotating shaft 13 to rotate, and when the first rotating shaft 13 rotates, the paddles 14 will rotate with the rotation of the first rotating shaft 13, so that the raw material can be crushed, and when the first rotating shaft 13 rotates, the support plate 15 will also drive the first scraper 16 rotates along the inner wall of the pulverizer body 1 with the first rotating shaft 13, and at the same time, when the first scraper 16 rotates, it will drive the brush plate 17 to rotate, so that the raw materials on the surface of the screen plate 11 can be screened. In this step, the raw materials adhering to the inner wall of the pulverizer body 1 can be cleaned by the action of the first scraper 16, and the raw materials on the inner wall are scraped to the middle part of the pulverizer body 1 so that they can contact with the blade 14, so as to prevent the blade 14 from being difficult to crush the raw materials adhering to the inner wall, thereby resulting in a situation where the raw material crushing accuracy is not high. The qualified raw materials can be screened out by the action of the brush plate 17, and the unqualified raw materials continue to remain in the pulverizer body 1 for crushing, so as to save the space inside the pulverizer body 1, and the next batch of raw materials can be added during the crushing of the pulverizer body 1, thereby improving production efficiency and reducing working time.

[0026] like Figure 1 , Figure 6 As shown, multiple groups of fans 2 are fixedly connected to the top of the crusher body 1; a cross support frame 21 is fixedly connected to the middle of the fans 2; a second rotating shaft 22 is rotatably connected to the middle of the cross support frame 21; multiple groups of fan blades 23 are fixedly connected to the middle of the second rotating shaft 22; when working, the cross support frame 21 plays a role of supporting the second rotating shaft 22. When the fan 2 is needed to work, the second rotating shaft 22 can be rotated first to drive the fan blades 23 to rotate. The rotation of the fan blades 23 can form a certain wind force. This step can be used to blow and clean the inside of the crusher body 1 when the crusher body 1 stops working through the action of the fan 2, so as to prevent the crushed raw material fragments from easily adhering to the surface of the first rotating shaft 13 and the blades 14 when the crusher body 1 is crushing the raw materials, thereby causing cleaning to be more troublesome and affecting the working process.

[0027] like Figure 1 , Figure 2 , Figure 4 , Figure 5As shown, the inner walls on both sides of the crusher body 1 are provided with slide grooves 3; the middle of the slide grooves 3 are slidably connected with second scrapers 31; the middle of the second scraper 31 is fixedly connected with multiple groups of pillars 32; the ends of the pillars 32 are fixedly connected with pull plates 33; the middle of the second scraper 31 is fixedly connected with tamping columns 34; during operation, the crushed raw materials will fall to the bottom of the crusher body 1 under the screening of the brush plate 17. When it is necessary to collect them for subsequent processing, the pull plate 33 can be held and pulled first. At this time, the pillar 32 will be affected by the pull plate 33 to drive the second scraper 31 to slide inside the slide groove 3. The second scraper 31 will move with the crushed raw materials when sliding. This step can facilitate the workers to collect the crushed raw materials through the action of the second scraper 31, thereby shortening the time required for the collection work and improving work efficiency.

[0028] like Figure 2 , Figure 4 , Figure 5 As shown, both ends of the second scraper 31 are rotatably connected to the third shaft 4; the middle of the third shaft 4 is fixedly connected to a groove roller 41; the middle of the groove roller 41 is slidably connected to a limit plate 42; during operation, when the second scraper 31 slides, the third shaft 4 will rotate under the influence of the second scraper 31, and at the same time, the groove roller 41 will roll forward at the limit plate 42 as the third shaft 4 rotates. This step can assist the second scraper 31 to slide through the cooperation of the third shaft 4 and the groove roller 41, so that the sliding of the second scraper 31 becomes smoother, and the rolling trajectory of the groove roller 41 can be limited by the action of the limit plate 42, so as to prevent the second scraper 31 from sliding out of the chute 3 when sliding, thereby affecting the collection work of the second scraper 31.

[0029] like Figure 1 , Figure 4 As shown, a plurality of hinges 51 are connected to the side of the pulverizer body 1; the middle of the hinges 51 are connected to a baffle 5; during operation, when the second scraper 31 moves with the crushed raw materials, the tamping column 34 will first support the baffle 5, and at this time, the pulling plate 33 is continued to be pulled, and the tamping column 34 will push open the baffle 5 under the rotation characteristics of the hinge 51. In this step, the baffle 5 and the hinge 51 cooperate with each other to assist the second scraper 31 to collect the crushed raw materials, so that the raw materials cleaned by the second scraper 31 can be smoothly scraped out to the inside of the pulverizer body 1, thereby further shortening the time required for the collection work and improving production efficiency.

[0030] like Figure 1As shown, the end of the fan 2 is fixedly connected with a valve plate 6; when the fan 2 is working, the valve plate 6 will expand under the influence of the wind brought by the fan 2, and the valve plate 6 will be in a closed state when the fan 2 is not working. This step can reduce the dust and impurities from the outside through the valve plate 6 when the fan 2 is not working. Pollutants such as dust and impurities may float into the inside of the grinder body 1 through the fan 2, thereby causing pollution to the inside of the grinder body 1.

[0031] like Figure 1 As shown, a fastening ring 7 is fixedly connected to the middle of the servo motor 12; a plurality of groups of legs 71 are fixedly connected to the middle of the fastening ring 7; during operation, when the servo motor 12 is working, it is easy to vibrate. At this time, the servo motor 12 can be fixed under the action of the fastening ring 7 and the legs 71 to reduce the vibration of the servo motor 12. This step, through the cooperation of the fastening ring 7 and the legs 71, can prevent the servo motor 12 from vibrating and thus affecting its ability to drive the first rotating shaft 13 to perform crushing.

[0032] Working principle: during operation, the raw materials to be crushed are first placed on the surface of the screen plate 11, and then the servo motor 12 is operated to drive the first rotating shaft 13 to rotate. When the first rotating shaft 13 rotates, the paddle 14 will rotate along with the rotation of the first rotating shaft 13, so that the raw materials can be crushed. When the first rotating shaft 13 rotates, the support plate 15 will also drive the first scraper 16 to rotate along the inner wall of the crusher body 1 along with the first rotating shaft 13. At the same time, when the first scraper 16 rotates, it will drive the brush plate 17 to rotate, so that the raw materials on the surface of the screen plate 11 can be screened. In this step, the raw materials adhering to the inner wall of the crusher body 1 can be cleaned through the action of the first scraper 16, and the raw materials on the inner wall can be scraped to the middle of the crusher body 1. The brush plate 17 can be used to sieve out qualified raw materials, and unqualified raw materials can continue to be retained in the grinder body 1 for grinding, so as to save space inside the grinder body 1, and the next batch of raw materials can be added during the grinding process of the grinder body 1, thereby improving production efficiency and reducing working time. When working, the cross support frame 21 plays a role of supporting the second rotating shaft 22. When the fan 2 needs to work, the second rotating shaft 22 can be rotated first to drive the fan blades 23 to rotate. The rotation of the fan blades 23 can form a certain wind force. This step is achieved by the fan 2 The function is to blow and clean the inside of the grinder body 1 when the grinder body 1 stops working, so as to prevent the crushed raw material fragments from easily adhering to the surface of the first rotating shaft 13 and the blade 14 when the grinder body 1 is crushing the raw material, thereby causing troublesome cleaning and affecting the working process. During operation, the crushed raw material will fall to the bottom of the grinder body 1 under the screening of the brush plate 17. When it is necessary to collect it for subsequent processing, the pull plate 33 can be held and pulled first. At this time, the support 32 will be affected by the pull plate 33 to drive the second scraper 31 to slide inside the slide 3. The second scraper 31 will move with the crushed raw material when sliding. This step can be achieved through the function of the second scraper 31 The third rotating shaft 4 will rotate under the influence of the second scraper 31 when the second scraper 31 slides, and the groove roller 41 will roll forward at the position of the limiting plate 42 as the third rotating shaft 4 rotates. This step can assist the sliding of the second scraper 31 through the cooperation between the third rotating shaft 4 and the groove roller 41, so that the sliding of the second scraper 31 becomes smoother. The rolling trajectory of the groove roller 41 can be limited by the action of the limiting plate 42, so as to prevent the second scraper 31 from sliding out of the chute 3 when sliding, thereby affecting the collection work of the second scraper 31.When the second scraper 31 moves with the crushed raw materials, the tamping column 34 will first support the baffle 5. At this time, continue to pull the pull plate 33, and the tamping column 34 will push open the baffle 5 under the rotation characteristics of the hinge 51. This step can assist the second scraper 31 to collect the crushed raw materials through the cooperation of the baffle 5 and the hinge 51, so that the raw materials cleaned by the second scraper 31 can be smoothly scraped out to the inside of the pulverizer body 1, thereby further shortening the time required for the collection work and improving the production efficiency. When working, when the fan 2 is working, the valve plate 6 will be affected by the wind force brought by the fan 2 and expand, and when the fan 2 is not working, the valve plate 6 will be in a closed state. This step can reduce the dust and impurities from the outside through the effect of the valve plate 6 when the fan 2 is not working. Pollutants such as dust and impurities may float into the inside of the pulverizer body 1 through the fan 2, thereby causing pollution to the inside of the pulverizer body 1. When working, when the servo motor 12 is working, it is easy to vibrate. At this time, the servo motor 12 can be fixed under the effect of the fastening ring 7 and the support leg 71 to reduce the vibration of the servo motor 12. This step can prevent the servo motor 12 from vibrating and affecting its ability to drive the first rotating shaft 13 to perform pulverization.
