Description

Technical Field

[0001] The invention relates to the technical field of plastic waste recycling, in particular to a waste recycling device for producing plastic woven cloth. Background Art

[0002] Plastic woven bags are a type of packaging material made from polypropylene (PP) or polyethylene (PE) as the main raw material, which is extruded and stretched into flat yarn, and then woven and made into bags. They are commonly known as "snakeskin bags". Since plastic woven bags will produce a large amount of scraps and unqualified products during the production process, and the waste after being used in large quantities in daily life is difficult to degrade naturally, a large amount of recycled materials are usually used in the production of plastic woven fabrics.

[0003] For example, Chinese patent number CN222039280U discloses a waste recycling device for plastic woven fabric production, which belongs to the technical field of woven fabric production. A waste recycling device for plastic woven fabric production comprises: a main body, wherein a crushing chamber, a heating chamber and a condensing chamber are provided on the inner side of the main body, a partition is installed at an equal angle on the top of the heating chamber, a rotating block is installed at the bottom of the heating chamber, the rotating block cooperates with the partition, a rotating rod 1 is installed at the bottom of the rotating block, a gear 1 is installed on the surface of the rotating rod 1, a turntable is meshed with the surface of the gear 1, and a tooth block is installed at an equal angle on the side of the turntable, the tooth block cooperates with the gear 1. The waste recycling device for plastic woven fabric production transfers the waste from the feed chamber to the melting chamber and then to the discharge chamber. Since the rotating block rotates intermittently, the waste in the melting chamber is fully heated; then the waste is discharged by the motor 2 driving the screw push rod, which is highly practical.

[0004] However, since waste fibers are easily entangled (especially woven fabric structures), the fiber bundles are tightly intertwined to form a three-dimensional network structure similar to a "chain", which not only increases the shear path but also increases the toughness of the material, resulting in high motor power consumption, rapid blade wear, and uneven crushing during crusher processing. The waste cannot be processed into uniform particles, which in turn affects the quality of subsequent melt regeneration. Summary of the Invention

[0020] 2. The present invention utilizes the extrusion effect of the hard agglomerates on the two sets of cutting parts to drive the rotating sleeve to move radially away from the central rotating shaft.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] See also Figures 1 to 11 The present invention provides a technical solution: a device for recycling and reusing waste materials used in the production of plastic woven fabrics, comprising a housing 1, a top surface of the housing 1 being provided with a material inlet and a bottom end being provided with a material outlet, a cutting assembly being provided in the housing 1, the cutting assembly comprising a rotating shaft 5 and a rotating sleeve 8 which are installed in the housing 1 and can be rotatably adjusted, the outer walls of the rotating shaft 5 and the rotating sleeve 8 being provided with multiple groups of cutting portions, and adjacent cutting portions being arranged in a staggered manner, and a rotatable sawtooth ring 20 being provided between every two groups of cutting portions on the rotating shaft 5 or the rotating sleeve 8;

[0036] The cutting assembly further includes an adjustment assembly for adjusting the distance between the rotating shaft 5 and the rotating sleeve 8;

[0037] The cutting assembly further comprises a speed changing assembly, which can synchronously adjust the rotation speeds of the rotating shaft 5 and the rotating sleeve 8 when the distance between the rotating shaft 5 and the rotating sleeve 8 changes.

[0038] "Waste recycling" in the production of plastic woven bags usually includes two sources at the same time. One is the scraps, waste silk, and unqualified products generated by processes such as drawing, weaving, cutting, and printing. The other is discarded woven bags (such as fertilizer bags and cement bags), which are collected by the social recycling system. Since the fibers of plastic woven bags are easily entangled, the fiber bundles are tightly intertwined to form a three-dimensional network structure similar to a "chain", which not only increases its shear path, but also increases the toughness of the material, causing the cutting machine to consume high power, wear the blade quickly, and crush unevenly when crushing and cutting the plastic woven bags. The waste cannot be processed into uniform particles, and the waste is easily heated unevenly during the melting stage, which in turn affects the subsequent recycling quality of the plastic.

[0039] When the device is in use, the waste plastic woven bags are first placed into the housing 1 from the feed port, and the external driving structure drives the rotating shaft 5 and the rotating sleeve 8 to rotate relative to each other, driving the multiple groups of cutting parts thereon to crush and cut the waste. Since the cutting parts on the two shafts are staggered, see the specific Figure 10 The shavings 20 are preferably cut and shredded by the sawtooth rings 20 when the sawtooth rings 20 rotate relative to each other, so that the waste can be cut in a relatively loose state by the cutting part, thereby reducing the power consumption during crushing and cutting and reducing the wear of the blade. When hard lumps or knots appear in the waste, the adjusting component drives the rotating shaft 5 and the rotating sleeve 8 to move relatively far apart, so as to prevent the hard lumps from squeezing the tool and causing damage or collapse of the cutting part. At the same time, the speed change component adjusts the rotation speed of the synchronous rotating shaft 5 and the rotating sleeve 8 to increase the differential speed between the rotating shaft 5 and the rotating sleeve 8, thereby increasing the tearing force of the two sets of serrated rings 20 on the waste, further loosening the lumps or knotted lumps, and increasing the cutting force between the cutting parts to crush the lumps. This can not only improve the uniformity of the waste cutting by the device, but also reduce the wear of the tool and the power consumption of crushing during the cutting process, thereby improving the service life of the device and the quality of subsequent plastic recycling.

[0040] In this way, the waste is cut by the cutting part while the serrated ring 20 is used to tear the waste loose, and the spacing is adjusted to prevent extrusion and the differential speed is used to enhance the tearing or cutting effect. The problems of high power consumption, fast tool wear, easy collapse, difficult hard block processing, and uneven cutting when cutting plastic woven bag waste are effectively solved, and the cutting is made more uniform and the material is loosened more fully, which is beneficial to the stability and homogenization of the subsequent melting and re-granulation process of the plastic, and ultimately improves the quality of recycled plastic products.

[0041] Furthermore, the serrated ring 20 is rotatably mounted on the rotating shaft 5 and the outer wall of the rotating sleeve 8 through the connecting block 23. Tooth buds are distributed in an annular manner on the inner ring of the serrated ring 20. The rotating shaft 5 and the outer wall of the rotating sleeve 8 are fixedly mounted with rotating gears 18 corresponding to the serrated ring 20. A driven gear 19 rotatably mounted on the inner wall of the housing 1 through a connecting plate 22 is provided between each group of rotating gears 18 and the inner ring of the serrated ring 20, and the driven gear 19 is respectively engaged with the inner ring of the serrated ring 20 and the rotating gear 18.

[0042] According to the above embodiment, a specific embodiment of a serrated ring 20 is provided. Figure 2The driven gear 19 is always kept in mesh with the rotating gear 18 through the connecting plate 22 fixed to the inner wall of the housing 1, and the serrated ring 20 is rotatably installed on the outer wall of the rotating shaft 5 and the rotating sleeve 8 through the connecting block 23. The rotating gear 18 can be driven to rotate together by the rotation of the rotating shaft 5 and the rotating sleeve 8, and the serrated ring 20 can be driven to rotate by the driven gear 19, and the rotation direction of the serrated ring 20 can be kept opposite to that of the rotating shaft 5 and the rotating sleeve 8. Even if the rotation direction between the serrated ring 20 and the cutting part is opposite, the serrated ring 20 can tear the waste by rotating in the opposite direction when the cutting part cuts the waste, and the tearing force of the serrated ring 20 on the waste and the shearing force of the cutting part on the waste are increased by increasing the differential speed between the serrated ring 20 and the cutting part.

[0043] Furthermore, the adjustment component includes a slide groove opened on the inner wall of the shell 1 near the side of the rotating sleeve 8, a sliding block 24 is slidably installed in the slide groove, and the driven gear 19 on this side is rotatably installed on the outer wall of the sliding block 24 through the connecting plate 22, and multiple groups of springs 25 are provided between the side wall of the sliding block 24 and the inner wall of the slide groove, cavities 3 are opened on both sides of the shell 1, and sliders 4 are slidably installed on the inner walls of the two groups of cavities 3, and the ends of the rotating sleeve 8 that penetrate into the cavities 3 on both sides are rotatably installed on the side walls of the two sliders 4, and the side walls of the cavity 3 are opened with flat grooves for the rotating sleeve 8 to slide.

[0044] According to the above embodiment, a specific embodiment of the adjustment component is provided. Figure 4 When the waste is in a relatively loose state, the rotating shaft 5 and the cutting parts outside the rotating sleeve 8 rotate alternately with each other, and drive the serrated ring 20 to rotate in the opposite direction to loosen and tear the waste. When hard lumps or knots appear in the waste, the two groups of opposite cutting parts are squeezed away from each other by the lumps, so that the rotating sleeve 8 is away from the rotating shaft 5 under the action of the squeezing force, increasing the cutting gap between the two groups of cutting parts, making room for the hard lumps, avoiding excessive squeezing of the tool cutting part, thereby preventing the tool from being damaged, broken or stuck.

[0045] Furthermore, the speed change assembly includes two transmission gears 27 respectively fixedly mounted on the rotating shaft 5 and the end of the rotating sleeve 8 passing through the cavity 3. The ends of the rotating shaft 5 and the rotating sleeve 8 passing through the cavity 3 are both rotatably mounted with a connecting long plate 2. The side walls of the two groups of connecting long plates 2 are both rotatably mounted with moving gears 28 respectively meshing with the two transmission gears 27, and the two groups of moving gears 28 are meshed with each other. A connecting short plate 29 is rotatably connected between the rotating shafts of the two groups of moving gears 28.

[0046] According to the above embodiment, a specific embodiment of a speed change assembly is provided. Figure 5When the rotating sleeve 8 moves away from the rotating shaft 5 under the action of the extrusion force, the transmission gear 27 outside the rotating sleeve 8 also moves away from the transmission gear 27 on the outer wall of the rotating shaft 5, and pulls the two sets of moving gears 28 downward together through the connecting long plate 2. The two sets of moving gears 28 rotate relative to the two sets of transmission gears 27 during the downward movement. For example, when the rotating shaft 5 rotates clockwise, the rotating sleeve 8 rotates counterclockwise. When the rotating sleeve 8 moves away from the rotating shaft 5, the moving gear 28 near the rotating shaft 5 moves downward and rotates counterclockwise relative to the transmission gear 27 on its outer wall, so that the transmission gear 27 on the outer wall of the rotating shaft 5 increases the rotation speed together with the moving gear 28, and at the same time, the rotating sleeve 8 rotates counterclockwise. The movable gear 28 near the transmission gear 27 rotates clockwise relative to it, which can increase the rotation speed of the transmission gear 27 outside the rotating sleeve 8, that is, when the cutting portion outside the rotating sleeve 8 is moved away from the rotating shaft 5 under the action of the extrusion force of the mass, the rotation speed of the rotating sleeve 8 and the rotating shaft 5 is increased at the same time, and the relative differential speed between the rotating sleeve 8 and the cutting portion of the outer wall of the rotating shaft 5 is increased. While improving the cutting ability of the serrated ring 20 on the mass, the cutting and crushing ability of the cutting portion on the mass is also improved. On the basis of avoiding damage to the tool, the tearing force and cutting force of the device on the hard mass are improved, thereby improving the uniformity of the crushing of the waste plastic woven bags by the device, and ultimately improving the quality of recycled plastic products.

[0047] In this way, through the squeezing effect of the hard agglomerate on the two sets of cutting parts, the rotating sleeve 8 is moved away from the rotating shaft 5 while driving the two sets of transmission gears 27 to move away from each other, and the two sets of moving gears 28 are cooperated to increase the relative differential speed between the rotating sleeve 8 and the rotating shaft 5 and their respective rotation speeds, thereby achieving the purpose of improving the cutting ability of the serrated ring 20 on the agglomerate and improving the cutting and crushing ability of the cutting part on the agglomerate, making the cutting more uniform and the material looser, thereby improving the stability and homogenization of the subsequent melting and re-granulation process of the plastic.

[0048] Furthermore, the cutting portion located on the outer wall of the rotating shaft 5 is a fixed disk 26 fixed to the outer wall of the rotating shaft 5, and multiple groups of cutting blades are distributed in an annular manner on the outer wall of the fixed disk 26. The cutting portion located on the rotating sleeve 8 is an annular tool holder 16 fixedly installed on the outer wall of the rotating sleeve 8 through a connecting rod 17. Multiple groups of cutting knives 15 that can slide along their radial direction are installed in the annular tool holder 16, and a sliding rod 14 is fixedly installed on the side wall of the cutting knife 15. A rotatable rotating disk 13 is installed on the outer wall of the rotating sleeve 8. The side wall of the rotating disk 13 is provided with multiple groups of arc grooves corresponding to the sliding rod 14 one by one, and the side wall of the sliding rod 14 is fixedly installed with a sliding pin that can slide in the arc groove.

[0049] According to the above embodiment, a specific embodiment of a cutting portion is provided. Figure 2 and Figure 8The outer wall of the rotating shaft 5 is annularly distributed with multiple groups of cutting blades through a fixedly connected fixed disk 26, and the annular tool holder 16 on the outer wall of the rotating sleeve 8 is fixedly connected. At the same time, multiple groups of cutting knives 15 that can slide along its radial direction are installed in the annular tool holder 16, so that when the rotating disk 13 rotates under the drive of the external driving structure, the sliding pin on the side wall of the sliding rod 14 can drive the cutting knife 15 to slide and adjust along the radial direction of the annular tool holder 16, thereby increasing the contact area of ​​the tool with the waste, thereby improving the tool's cutting ability for hard lumps.

[0050] Furthermore, a rotating rod 7 is installed in the rotating sleeve 8, and the rotating rod 7 can slide and rotate in the rotating sleeve 8. A plurality of rotating grooves 10 are provided on the outer wall of the rotating sleeve 8. A clamping block 12 corresponding to the rotating groove 10 is fixedly installed on the inner wall of the rotating disk 13. The clamping block 12 can rotate in the rotating groove 10, and a sliding groove 11 for the clamping block 12 to slide is provided on the outer wall of the rotating rod 7. A spiral groove is provided on the inner wall of the rotating sleeve 8, and a limit pin that can slide in the spiral groove is fixedly installed on the outer wall of the rotating rod 7.

[0051] According to the above embodiment, it can be seen that when the rotating rod 7 slides and adjusts relative to the rotating sleeve 8, the limit pin on the outer wall of the rotating rod 7 will slide in the spiral groove on the inner wall of the rotating sleeve 8 and rotate, and drive the blocking block 12 and the rotating disk 13 to rotate together in the rotating groove 10 through the sliding groove 11, so as to achieve the purpose of driving the cutting knife 15 to slide and adjust along the radial direction of the annular knife holder 16 as mentioned above.

[0052] Furthermore, an inclined groove 21 is opened on the side wall of the cavity 3, and an extrusion head 9 is fixedly installed on the part where one end of the rotating rod 7 passes through the slider 4, and the extrusion head 9 contacts and abuts against the inclined edge of the inclined groove 21, and a compression spring 6 is provided between the other end of the rotating rod 7 and the slider 4.

[0053] According to the above embodiment, it can be known that when the rotating sleeve 8 moves away from the rotating shaft 5 under the action of the extrusion force, the rotating rod 7 in the rotating sleeve 8 is squeezed by the inclined groove 21 and begins to move horizontally and adjust and rotate at the same time. That is, when the cutting part is squeezed by the hard agglomerate, the two groups of cutting parts move away from each other to leave a gap for the agglomerate to pass through. At the same time, the cutting knife 15 outside the rotating sleeve 8 extends outward to improve the cutting and crushing ability of the agglomerate, and cooperates with the serrated ring 20 to tear the agglomerate to reduce the toughness and hardness of the agglomerate. On the basis of providing wear protection for the cutting knife 15 and the cutting edge, the processing ability of the agglomerate is improved, thereby improving the uniformity of the crushing of the waste.

[0054] In this way, when the cutting part is squeezed by the hard lump, the rotating sleeve 8 is driven away from the rotating shaft 5, and the cutting knife 15 outside the rotating sleeve 8 is driven to extend outward, thereby improving the processing capacity of the lump on the basis of providing wear protection for the cutting knife 15 and the cutting edge, and cooperating with the serrated ring 20 to tear the lump to reduce the toughness and hardness of the lump, and at the same time using the speed change component to improve the tearing ability of the serrated ring 20 on the lump and the cutting force of the cutting knife 15 and the cutting edge on the lump, further making the cutting more uniform and the material looser.

[0055] Furthermore, the cutting components are arranged into two groups, upper and lower, and the two groups are arranged in a centrally symmetrical manner.

[0056] According to the above embodiment, the cutting assembly is arranged into two groups, and the two groups are arranged symmetrically in the center. When the waste passes through the upper cutting assembly, if the hard agglomerate squeezes the rotating sleeve 8, the transmission gear 27 outside the rotating sleeve 8 is accelerated by the two groups of moving gears 28, so that the rotation speed of the rotating sleeve 8 is higher than the rotating shaft 5, that is, the waste will deviate toward the rotating sleeve 8 and bend and agglomerate below it, and then the loose agglomerates enter the lower cutting assembly. If there are still hard agglomerates in the waste after being cut once, the lower rotating sleeve 8 will deviate to the right. For details, see Figure 5 , causing the transmission gear 27 on the outer wall of the lower rotating shaft 5 and the moving gear 28 near it to rotate counterclockwise, reducing the rotation speed of the transmission gear 27 on the outer wall of the rotating shaft 5, and at the same time, the transmission gear 27 on the outer wall of the lower rotating sleeve 8 and the moving gear 28 near it to rotate clockwise, increasing the rotation speed of the transmission gear 27 on the outer wall of the rotating sleeve 8, further increasing the differential speed between the lower cutting part and the serrated ring 20, so that the lower cutting component can improve its cutting and tearing force on the waste while reversely cutting and tearing the loose clumps, further destroying the toughness and hardness of the waste, and improving the uniformity of the device in processing waste.

[0057] Furthermore, the two sets of rotating shafts 5 pass through one end of the housing 1 and are driven by a pulley.

[0058] According to the above embodiment, the two sets of rotating shafts 5 are driven to rotate together by the pulley, so that the two sets of rotating shafts 5 can slip relative to each other when affected by the speed change assembly to change the transmission ratio therebetween.

[0059] Furthermore, a shock-absorbing spring and shock-absorbing cotton are provided at the bottom end of the shell 1.

[0060] According to the above embodiment, it can be seen that by arranging a shock-absorbing spring and shock-absorbing cotton at the bottom end of the shell 1, the vibration of the device when cutting and crushing waste can be reduced, thereby avoiding the impact of vibration on the operation of the device.

[0061] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and drawings can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description will be given here.

[0062] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
