Description

Technical Field

[0001] The present invention belongs to the technical field of plastic processing, and specifically relates to a hot-melt device for modified plastic processing. Background Art

[0002] Modified plastics are materials formed by plasticizing or curing and crosslinking with a high-molecular-weight synthetic resin as the main component. Plastics mainly consist of synthetic resins and various additives, including plasticizers, stabilizers, antioxidants, etc. These additives together determine the performance and application range of plastics. When processing plastics, a hot-melt device is usually used to crush the plastics, and then heat and melt them, and then extrude them to manufacture plastic pellets.

[0003] A patent with the publication number CN113910494B discloses a hot-melt device for recycling and reusing waste plastics. The device drives a first stirring rod and a second stirring rod to rotate through a first rotating shaft, so as to stir and clean the plastics in the cleaning box shell. Then, the waste water is filtered through a filter plate and activated carbon, and the plastics are hot-melted by a heating device. Then, as the feeding screw rotates, the hot-melted plastics are extruded. The first motor drives the first rotating shaft and the rotating wheel installed at the upper end of the first rotating shaft to rotate, so as to change the position of the first feeding plate, so as to realize intermittent feeding of waste feed. And through the rotation of the first rotating shaft, the first stirring rod and the second stirring rod are driven to rotate, so as to stir and clean the waste plastics in the cleaning box shell, so that manual cleaning is no longer required, which is more time-saving and labor-saving. The heating device is started to work, and then the plastics in the inner end of the hot-melt box are hot-melted through a heat conduction plate made of aluminum. Then, through the rotation of the third motor, the feeding screw is driven to rotate, so as to feed and extrude the hot-melted plastics, which is convenient for subsequent reuse of waste plastics.

[0004] The above solution still has some problems in actual application. When processing plastics, a rotating shaft is usually used to drive multiple cutting knives to cut and crush the modified plastic film. However, after part of the plastic film is cut, it will wind around the outside of the rotating shaft. If it is not cleaned in time, more and more will wind around the outside of the rotating shaft, which will affect the rotation efficiency of the rotating shaft and the cutting efficiency of the subsequent film. If the machine is stopped at this time to clean the plastic film wound around the outside of the rotating shaft, it will not only waste the processing time of the plastic film, but also the workers will be affected by the blades when cleaning the film wound around the outside of the rotating shaft, resulting in potential safety hazards.

DETAILED DESCRIPTION OF THE INVENTION

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0022] Example 1: As Figures 1 to 7 shown, a hot-melt device for modified plastic processing according to an embodiment of the present invention includes a hot-melt machine main body 2, a feeding frame 4 installed at its upper end, and a processing cylinder 5 fixedly communicated with the upper end of the feeding frame 4. A base 1 is fixedly connected to the lower end of the hot-melt machine main body 2. A conveying cylinder 9 is fixedly communicated with one side of the hot-melt machine main body 2. A sealing plate 10 is installed on one side of the conveying cylinder 9, and a plurality of through holes are opened on one side of the sealing plate 10 for extruding and manufacturing plastic particles. A feeding port 6 is opened on one side of the processing cylinder 5. Two flipping covers 7 are rotatably connected to the inner cavity of the feeding port 6. A plastic processing component is rotatably connected to the inner cavity of the processing cylinder 5; And the plastic processing component includes a rotating column 12 rotatably connected. A rotating groove 16 is opened inside the rotating column 12. A bidirectional lead screw 14 is rotatably connected to the inner cavity of the rotating groove 16. Two sliding disks 17 are threadedly connected to the outside of the bidirectional lead screw 14. And a first cutting knife 25 is fixedly connected to the outside of the two sliding disks 17. A plurality of second cutting knives 26 are fixedly connected to the outside of both ends of the rotating column 12. And the first cutting knife 25 and the second cutting knife 26 cooperate to cut and recycle the plastic film wound around the outside of the rotating column 12; Four groups of blades 13 are annularly arranged on the outside of the rotating column 12. Each group of blades 13 is arranged in an array of a plurality of blades, and the four groups of blades 13 are arranged in a staggered manner, which can increase the efficiency of cutting modified plastic.

[0023] Specifically, in the prior art, it is usually to drive a rotating shaft to drive a plurality of cutting knives to cut and crush a modified plastic film. However, after part of the plastic film is shredded, it will be wound around the outside of the rotating shaft. If it is not cleaned in time, more and more will be wound around the outside of the rotating shaft, which will affect the rotation efficiency of the rotating shaft and also affect the subsequent cutting efficiency of the film. If the machine is stopped at this time to clean the plastic film wound around the outside of the rotating shaft, it will not only waste the processing time of the plastic film, but also the workers will be affected by the blades when cleaning the film wound around the outside of the rotating shaft, resulting in potential safety hazards; The present invention puts the modified plastic film into the inner cavity of the feeding port 6 and squeezes the flip cover 7 in the inner cavity of the feeding port 6 to flip it open, while driving the rotating column 12 to rotate and driving the four sets of blades 13 to rotate synchronously. The four sets of blades 13 are staggered with each other, so that the modified plastic film put into the inner cavity of the processing cylinder 5 can be quickly cut and crushed. The staggered setting of the blades 13 can be used for cutting and crushing other different plastics. During the rotation of the rotating column 12, the sliding plate 17 is also driven to rotate synchronously, and the sliding plate 17 is threadedly connected to the bidirectional screw rod 14 to slide back and forth, thereby driving the first cutting knife 25 to move synchronously. After the sliding plate 17 drives the first cutting knife 25 to move to both ends of the rotating column 12, the first cutting knife 25 will contact the second cutting knife 26, thereby cutting the modified plastic wrapped around the outside of the rotating column 12. The film is cut, and the first cutting knife 25 is provided with two cutting edges, which drives the driving slide plate 17 to move closer to each other. During the movement, the slide plate 17 will drive the first cutting knife 25 to move closer to each other, thereby further cutting the modified plastic film, avoiding too much plastic film wrapped around the outside of the rotating column 12, affecting the rotation of the rotating column 12 and reducing the efficiency of cutting and crushing the plastic film. The modified plastic film after cutting and crushing will fall into the inner cavity of the guide rack 4, and at the same time fall into the inner cavity of the hot melt machine body 2 through the guide rack 4, and then the modified plastic film that falls in is heated and melted by the hot melt machine body 2, and at the same time conveyed to the inner cavity of the conveying cylinder 9, and a number of through holes are opened on one side of the sealing plate 10, and then the melted modified plastic is extruded through the through holes of the sealing plate 10, thereby facilitating the recycling of the modified plastic, thereby solving the above-mentioned problem.

[0024] like Figure 1 、 Figure 5 and Figure 6 As shown, an insert block 15 is fixedly connected to one end of the bidirectional screw rod 14 , a mounting plate 11 is installed on one side of the treatment cylinder 5 , and the insert block 15 is plugged into the mounting plate 11 .

[0025] Specifically, when the rotating column 12 drives the sliding plate 17 to rotate, the insert block 15 is limited by the mounting plate 11, thereby preventing the rotation of the bidirectional screw rod 14, so that the sliding plate 17 is threadedly slid outside the bidirectional screw rod 14, thereby realizing the cutting of the plastic film wrapped around the outside of the rotating column 12.

[0026] like Figure 1 、 Figure 5 and Figure 6 As shown, a driving assembly 8 is provided at one end of the rotating column 12 passing through the processing cylinder 5. The driving assembly 8 includes a driven pulley 81 fixed to one end of the rotating column 12. The driven pulley 81 is externally connected to a belt 82, and one end of the belt 82 is connected to a driving pulley 83.

[0027] like Figure 4 、Figure 5 and Figure 6 As shown in Figure 6 , a plurality of tooth blocks are annularly arranged outside the transmission pulley 83, and the transmission pulley 83 is rotatably connected to the material guiding frame 4. A transmission gear 84 is meshed and connected to the outside of the transmission pulley 83. A driving motor 87 is arranged inside one side of the material guiding frame 4, and the output shaft end of the driving motor 87 is fixedly connected to the transmission gear 84.

[0028] Specifically, by starting the driving motor 87 to drive the transmission gear 84 to rotate, and making the transmission gear 84 cooperate with the tooth blocks to drive the transmission pulley 83 to rotate. At the same time, the transmission pulley 83 drives the belt 82 to rotate, and then drives the driven pulley 81 to rotate. And the driven pulley 81 will drive the rotating column 12 to rotate, and at the same time drive the blade 13 to cut and crush the plastic film.

[0029] As Figure 1 、 Figure 5 and Figure 6 As shown in Figure 6 , the transmission gear 84 is meshed and connected to a second gear 88, and the second gear 88 is rotatably connected to the material guiding frame 4. The second gear 88 is meshed and connected to a first gear 85, and the first gear 85 is rotatably connected to the material guiding frame 4.

[0030] Embodiment 2: As Figure 1 、 Figure 5 and Figure 7 As shown in Figure 7 , both ends of the transmission pulley 83 and the first gear 85 are fixedly connected with intermittent clamping blocks 86. The intermittent clamping blocks 86 are rotatably connected to a U-shaped rotating sleeve 18, and a semi-circular rotating cover 19 is fixedly connected to one side of the U-shaped rotating sleeve 18.

[0031] As Figure 1 、 Figure 5 and Figure 7 As shown in Figure 7 , the U-shaped rotating sleeve 18 is rotatably connected to the inner wall of the material guiding frame 4, and an elastic member 20 is arranged inside the U-shaped rotating sleeve 18.

[0032] Specifically, when the driving rotating column 12 drives the blade 13 to cut the plastic film in the processing cylinder 5, the driving transmission gear 84 is rotated counterclockwise, and then meshes with the transmission second gear 88 to rotate clockwise, and the second gear 88 meshes with the transmission first gear 85 to rotate counterclockwise. At the same time, the transmission gear 84 cooperates with the tooth block to drive the transmission pulley 83 to rotate clockwise, so that the transmission pulley 83 and the first gear 85 drive the intermittent block 86 to rotate. After the intermittent block 86 rotates one circle, it will abut against the elastic member 20 on the inner wall of the U-shaped rotating sleeve 18, and then drive the U-shaped rotating sleeve 18 to rotate. At the same time, the U-shaped rotating sleeve 18 drives the semi-circular rotating cover 19 to flip open the inner cavity of the processing cylinder 5, and the crushed plastic film in the inner cavity of the processing cylinder 5 will fall into the inner cavity of the material guiding frame 4. After the semi-circular rotating cover 19 rotates to open the processing cylinder 5, the semi-circular rotating cover 19 drives the rotating shaft 21 to rotate, and at the same time the rotating shaft 21 drives the fixed disk 22 to rotate, and then drives the torsion spring 23 to twist. After the semi-circular rotating cover 19 abuts against the inner wall of the material guiding frame 4 and cannot rotate, the intermittent block 86 will squeeze the elastic member 20 to disengage from the abutment, and then the torsion spring 23 twists the fixed disk 22 to rotate and reset. At the same time, the fixed disk 22 drives the rotating shaft 21 to rotate, and then drives the semi-circular rotating cover 19 to flip and reset, so as to seal the inner cavity of the processing cylinder 5 again, so as to realize intermittent feeding into the inner cavity of the main body 2 of the hot melt machine, and avoid feeding a large amount of plastic film into the inner cavity of the main body 2 of the hot melt machine at one time, resulting in difficulty in quickly heating and melting a large amount of plastic film in the inner cavity of the main body 2 of the hot melt machine, affecting the manufacturing quality of subsequent plastic particles, and causing defects such as air bubbles and cracks in the workpiece when using plastic particles for injection molding of workpieces, thereby solving the problem that when the existing hot melt equipment for modified plastic processing processes and recycles modified plastic films, due to the inconvenience of quantitatively feeding the crushed plastic film into the hot melt machine, the quality of the processed plastic particles does not meet the standard, affecting the quality of the workpieces manufactured using plastic particles.

[0033] As Figures 4 to 7 shown, the semi-circular rotating cover 19 is rotatably connected to the inner cavity of the material guiding frame 4. One end of the semi-circular rotating cover 19 is fixedly connected with a rotating shaft 21, and the rotating shaft 21 is rotatably connected inside the material guiding frame 4. A fixed disk 22 is fixedly connected to the outside of the rotating shaft 21. One side of the fixed disk 22 is fixedly connected with a torsion spring 23, and one end of the torsion spring 23 is fixedly connected to the inside of the material guiding frame 4.

[0034] As Figure 1 and Figure 4 shown, a servo motor 3 is installed on one side of the main body 2 of the hot melt machine. The output shaft end of the servo motor 3 penetrates through the main body 2 of the hot melt machine and is fixedly connected with a conveying auger 27. The conveying auger 27 is rotatably installed with the sealing plate 10.

[0035] As Figure 1 and Figure 4As shown, one end of the conveying auger 27 is equipped with a granulating knife 24, and the granulating knife 24 is in contact with the sealing plate 10, capable of cutting the plastic solution extruded by the sealing plate 10 to form granules.

[0036] Specifically, when intermittently discharging the shredded plastic film into the material guiding frame 4, the servo motor 3 is started to drive the conveying auger 27 to rotate. At the same time, the conveying auger 27 agitates the plastic film melted by heating in the inner cavity of the hot melt machine main body 2 for conveying, and conveys the heated and melted plastic film into the inner cavity of the conveying cylinder 9. Meanwhile, the melted plastic film in the inner cavity of the conveying cylinder 9 is extruded through the through hole of the sealing plate 10. During the rotation of the conveying auger 27, the granulating knife 24 is also driven to rotate, and the granulating knife 24 cuts the plastic solution extruded through the through hole of the sealing plate 10. Then, a collection box filled with clear water is arranged below the conveying cylinder 9, so that the plastic solution generated by the cutting of the granulating knife 24 falls into the collection box for cooling to form plastic particles, thus realizing the cyclic granulation of the hot melt equipment. Moreover, it can also reduce the volume of the hot melt equipment, making its installation and use more convenient, and solving the problem that the existing hot melt equipment for modified plastic processing has a large volume. When processing the modified plastic film, the extruded plastic solution needs to pass through a water tank and then be placed under the cutting knife for cutting and granulation, which is not only costly but also inconvenient to use.

[0037] Working principle: Put the modified plastic film into the inner cavity of the feeding port 6, and squeeze the flip cover 7 in the inner cavity of the feeding port 6 to turn it over and open. At the same time, drive the rotating column 12 to rotate, and drive the four groups of blades 13 to rotate synchronously. The four groups of blades 13 are arranged in a staggered manner, so that the modified plastic film put into the inner cavity of the processing cylinder 5 can be quickly cut and crushed. The staggered arrangement of the blades 13 can be used for the cutting and crushing treatment of other different plastics. During the rotation of the rotating column 12, the sliding disk 17 will also be driven to rotate synchronously, and the sliding disk 17 is threadedly connected to the bidirectional lead screw 14 to make a reciprocating slide, thereby driving the first cutting knife 25 to move synchronously. After the sliding disk 17 drives the first cutting knife 25 to move to both ends of the rotating column 12, the first cutting knife 25 will contact the second cutting knife 26, thereby cutting off the modified plastic film wound around the outside of the rotating column 12. The first cutting knife 25 is provided with two cutting edges. When driving the sliding disks 17 to move closer to each other, the sliding disks 17 will drive the first cutting knives 25 to move closer to each other, thereby further cutting off the modified plastic film, avoiding too much plastic film wound around the outside of the rotating column 12, affecting the rotation of the rotating column 12 and reducing the cutting and crushing efficiency of the plastic film. The cut and crushed modified plastic film will fall into the inner cavity of the material guiding frame 4, and at the same time, it will fall into the inner cavity of the hot melt machine main body 2 through the material guiding frame 4. Then, the hot melt machine main body 2 heats and melts the falling modified plastic film, and at the same time conveys it into the inner cavity of the conveying cylinder 9. A number of through holes are provided on one side of the sealing plate 10, and then the melted modified plastic is extruded through the through holes of the sealing plate 10, which is convenient for the recycling treatment of the modified plastic; When driving the rotating column 12 to drive the blade 13 to cut the plastic film in the processing cylinder 5, by driving the transmission gear 84 to rotate counterclockwise, then meshing and driving the second gear 88 to rotate clockwise, and the second gear 88 meshing and driving the first gear 85 to rotate counterclockwise. At the same time, the transmission gear 84 cooperates with the tooth block to drive the transmission pulley 83 to rotate clockwise, so that the transmission pulley 83 and the first gear 85 drive the intermittent block 86 to rotate. After the intermittent block 86 rotates one circle, it will abut against the elastic member 20 on the inner wall of the U-shaped rotating sleeve 18, and then drive the U-shaped rotating sleeve 18 to rotate. At the same time, the U-shaped rotating sleeve 18 drives the semi-circular rotating cover 19 to flip and open the inner cavity of the processing cylinder 5, and the crushed plastic film in the inner cavity of the processing cylinder 5 will fall into the inner cavity of the material guiding frame 4. After the semi-circular rotating cover 19 rotates to open the processing cylinder 5, the semi-circular rotating cover 19 drives the rotating shaft 21 to rotate, and at the same time the rotating shaft 21 drives the fixed disk 22 to rotate, and then drives the torsion spring 23 to twist. After the semi-circular rotating cover 19 abuts against the inner wall of the material guiding frame 4 and cannot rotate, the intermittent block 86 will squeeze the elastic member 20 to disengage from the abutment, and then the torsion spring 23 twists the fixed disk 22 to rotate and reset. At the same time, the fixed disk 22 drives the rotating shaft 21 to rotate, and then drives the semi-circular rotating cover 19 to flip and reset, so as to seal the inner cavity of the processing cylinder 5 again, so as to realize intermittent feeding into the inner cavity of the main body 2 of the hot melt machine, and avoid feeding a large amount of plastic film into the inner cavity of the main body 2 of the hot melt machine at one time, resulting in difficulty in quickly heating and melting a large amount of plastic film in the inner cavity of the main body 2 of the hot melt machine, affecting the manufacturing quality of subsequent plastic particles, and causing defects such as air bubbles and cracks in the workpiece when using plastic particles for injection molding of workpieces because there are unmolten plastic films inside the plastic particles; When intermittently discharging the crushed plastic film into the material guiding frame 4, by starting the servo motor 3 to drive the conveying auger 27 to rotate, at the same time the conveying auger 27 agitates the heated and melted plastic film in the inner cavity of the main body 2 of the hot melt machine for conveying, and makes the heated and melted plastic film be conveyed into the inner cavity of the conveying cylinder 9. At the same time, the melted plastic film in the inner cavity of the conveying cylinder 9 is extruded through the through hole of the sealing plate 10. During the rotation of the conveying auger 27, it will also drive the granulating knife 24 to rotate, and the granulating knife 24 cuts the plastic solution extruded from the through hole of the sealing plate 10. Then there is a collection box filled with clear water below the conveying cylinder 9, so that the plastic solution generated by the cutting of the granulating knife 24 falls into the collection box for cooling to form plastic particles, thus realizing the cyclic granulation of the hot melt equipment, and it can also reduce the volume of the hot melt equipment, making its installation and use more convenient.
