Description

Technical Field

[0001] The present invention relates to the technical field of mechanical equipment, and more specifically, to a disc-type friction device for recycling cloth fibers. Background Art

[0002] Friction pelletizer is suitable for the polymerization of various materials, such as plastics, rubber, resin, etc. It is widely used in plastic recycling, rubber regeneration, resin abrasive and other industries. In the process of thermoplastic production and processing, waste materials will be generated; friction pelletizing equipment processes these waste materials into free-flowing uniform particles, which are reused as valuable raw materials for downstream production. The material has great production flexibility during the processing process, and can process a variety of waste fibers and waste plastics, such as polyester, nylon, etc., and can also recycle waste cloth, waste film, etc.

[0003] The friction granulator uses the friction heating and softening method to granulate waste materials. Different fibers are softened by heat during friction granulation and are granulated. The softened particles are discharged only by the centrifugal force of the friction wheel rotation. However, the softened materials cannot be discharged smoothly due to the viscosity of the materials. In addition, the friction wheel will affect the granulation effect due to excessive friction during long-term use, and the existing friction wheels are mostly welded one-piece designs, which need to be replaced as a whole during the subsequent replacement process, thereby increasing the user's use cost and being unfavorable for the optimization and upgrading of the production line.

In the subsequent maintenance and inspection, it is only necessary to open the inspection door 104 to inspect the circuits or distributors in the storage cavity; like Figure 5-6As shown, the spiral conveying mechanism 20 includes an outer sleeve 201 and an auger core shaft 202 arranged inside the outer sleeve 201, and cooperates with its corresponding driving member to convey fiber waste and raw materials to the friction mechanism 40; a coupling 204 is provided at the connection between the auger core shaft 202 and the outer sleeve 201, and a feeding hopper 203 is fixedly provided on the top of the end of the outer sleeve 201 close to the driving motor Ⅰ30, and a tail bearing is provided at the end of the auger core shaft 202 away from the coupling 204 and the center of the moving flange 4061. The driving motor Ⅰ30 drives the auger core shaft 202 to rotate continuously in the outer sleeve 201. During this period, as the auger core shaft 202 spirally rotates, the material (waste material or small-diameter raw material after preliminary crushing) entering the outer sleeve 201 from the feed hopper 203 is transported toward the friction mechanism 40 (using the weight of the material itself and the friction resistance of the auger core shaft 202 to the material). The tail bearing and coupling 204 at the end of the auger core shaft 202 support the position of the auger core shaft 202, and the pipe holding platform 102 maintains the position of the outer sleeve 201, so as to maintain the stability during material transportation and effectively prevent the vibration of the auger core shaft 202 from affecting the normal operation of the friction mechanism 40. like Figure 4 As shown, the finished material extraction component 60 includes an external fixing frame 601, and a finished material conveying channel 602 is provided inside the external fixing frame 601. A relative discharge channel with only a finished material outlet 605 and a material inlet hopper 604 is formed by the external fixing frame 601 and the finished material conveying channel 602 on both sides. A driving impeller is provided inside the finished material conveying channel 602, and a driving motor II 603 is fixedly provided outside the external fixing frame 601. The output shaft of the driving motor II 603 passes through the external fixing frame 601 and is connected to the driving impeller. The driving impeller is driven to rotate at a high speed by the driving motor II 603, thereby forming a negative pressure airflow in the discharge channel, and the formed granular material in the processing cavity 402 is negatively pressured and extracted through the material inlet hopper 604 and the discharge hopper 404. A material feed hopper 604 is provided at the connection between one end of the material conveying channel 602 and the friction mechanism 40, and a material outlet 605 is provided at the other end of the material conveying channel 602. The driving motor II 603 drives the driving impeller to rotate, thereby generating a pulling force on the inner cavity of the friction mechanism 40 through the material feed hopper 604. A through hole I 403 is provided at the connection between the center of one side of the aggregate shell 401 and the outer sleeve 201. A discharge hopper 404 is provided on one side of the aggregate shell 401. The discharge hopper 404 is connected to the processing cavity 402. The discharge hopper 404 is fixed to the material feed hopper 604 by bolts. When the driving impeller is worn or damaged, the corresponding bolts of the external fixing frame 601 are disassembled to replace a more wear-resistant driving impeller. like Figure 7-8As shown, the friction mechanism 40 includes a material-gathering shell 401 and a disassembly shell plate 405, and a processing cavity 402 is formed between the material-gathering shell 401 and the disassembly shell plate 405. A friction group accessory 406 is arranged inside the processing cavity 402, and one end of the outer sleeve 201 penetrates through the material-gathering shell 401 and extends into the position of the friction group accessory 406; the friction group accessory 406 includes a movable convex disc 4061 and a fixed concave disc 4062, and a retaining ring frame 4063 is sleeved on the outer side of the movable convex disc 4061 and the fixed concave disc 4062, and the fixed concave disc 4062, the retaining ring frame 4063 and the disassembly shell plate 405 are fixed to the material-gathering shell 401 by bolts, and the output shaft of the driving motor I30 is connected to the auger core shaft 202 of the screw conveying mechanism 20, and the output shaft of the transmission motor 50 is connected to the center of the movable convex disc 4061 that penetrates through the disassembly shell plate 405; Specifically, Figure 1-8 As shown, the implementation method is specifically as follows: the drive motor I30 and the transmission motor 50 work synchronously, and the drive motor I30 drives the auger core shaft 202 to continuously spirally rotate, and the crushed materials and waste materials entering the outer sleeve 201 from the feed hopper 203 are transported to between the movable convex plate 4061 and the fixed concave plate 4062 in the friction mechanism 40. During this period, the transmission motor 50 drives the movable convex plate 4061 to rotate around the retaining ring frame 4063, and the contact friction and lateral shear between the movable convex plate 4061 and the fixed concave plate 4062 and the materials cause the materials to be heated and become sticky, thereby agglomerated into particles, which are then discharged from the retaining ring frame 4063 into the processing cavity 402 under the action of centrifugal force. At this time, the drive motor II 603 works to drive the drive impeller to rotate at a high speed, generating a negative pressure airflow, and the formed pellets in the processing cavity 402 follow the negative pressure airflow from the material inlet hopper 604 into the discharge channel, and are then centrally transported to the material storage device position from the material outlet 605.

[0033] Embodiment 2:

[0034] Based on the friction mechanism 40 proposed in Example 1, the present invention provides a further technical solution for the moving convex plate 4061 , the fixed concave plate 4062 and the retaining ring frame 4063 .

[0035] See also Figure 8-11The friction group accessory 406 includes a movable convex disc 4061 and a fixed concave disc 4062. The movable convex disc 4061 and the fixed concave disc 4062 are sleeved with a retaining ring frame 4063 on their outer sides. The movable convex disc 4061 includes a chassis Ⅰ 40611 and a boss disc 40612 whose size is smaller than that of the chassis Ⅰ 40611. The outer surface of the boss disc 40612 is set as a conical surface, and the center of the boss disc 40612 is set as a flat truncated table 40613, wherein the auger core shaft 202 is connected to the position of the flat truncated table 40613 through a tail bearing, and the processing cavity 402 forms a granular material processing space whose size is larger than that of the friction group accessory 406, and the assembled friction group accessory 406 is installed in the processing cavity 402 and the fixed concave disc 4062 is fixed to the aggregate shell 401 by bolts through bolt holes 40622, thereby ensuring that the relative position of the friction group accessory 406 in the processing cavity 402 is limited; The conical surface of the boss plate 40612 is evenly provided with material storage grooves 40614 in a circular array, and the lengths of the multiple material storage grooves 40614 are different. The material storage grooves 40614 are arranged along the axis of the boss plate 40612 (the radius line from the center point of the circle to the edge). The conical surface of the boss plate 40612 is provided with multiple rib grinding knives I 40615 in a circular array, and the rib grinding knives I 40615 are offset at an angle of 5°-10° with the alignment axis, and the rib grinding knives I 40615 protrude from the conical surface of the boss plate 40612.

A grinding toughness Ⅰ40619 is provided on one side of the rib grinding knife Ⅰ40615, and an annular rotating groove 40616 is provided at the edge of the boss plate 40612; the chassis Ⅰ40611 and the chassis Ⅱ40621 are equal in size, the boss plate 40612 and the concave plate 40625 are equal in outer diameter, and the inclination of the conical surface of the boss plate 40612 is less than the inclination of the concave surface of the concave plate 40625 (thereby ensuring that the fixed concave plate 4062 and the movable boss plate 4061 are installed on the retaining ring frame 406 3); the material enters the material temporary retention space from the screw conveying mechanism 20. Since the lengths of the storage grooves 40614 of different lengths are not set to the edge of the boss plate 40612, the material that has not been completely softened and granulated (if the block diameter is too large) is temporarily retained in the storage groove 40614, and then leaves the storage groove 40614 with the rotation of the movable convex plate 4061. The fiber raw material is sheared and crushed by the rib grinding knife I 40615 and the rib grinding knife II 40624, and the contact friction between the fixed concave plate 4062, the movable convex plate 4061 and the crushed material increases the temperature to granulate; See also Figure 12-15The fixed concave plate 4062 includes a chassis II 40621 and a concave platform plate 40625 smaller in size than the chassis II 40621. The outer surface of the concave platform plate 40625 is set as a concave cone. A through hole II 40623 is opened at the center of the concave platform plate 40625.

The lengths of the plurality of material distribution grooves 40627 are different. The concave surface of the concave plate 40625 is provided with a plurality of rib grinding knives II 40624 in a circular array, and the rib grinding knives II 40624 are protruding from the concave plate 40625. The concave surface of the concave platform 40625 and the rib grinding knife II 40624 are connected with a mounting groove II 40628, and the rib grinding knife II 40624 and the mounting groove II 40628 are both provided with mounting holes II 40629 at the positions where they are mounted, and the rib grinding knife II 40624 is fixed with a grinding toughness II 40620 on one side, and the rib grinding knife II 40624 and the mounting groove II 40628 are fixed with bolts; Specifically, the aggregated particles formed by the fixed concave plate 4062 and the moving convex plate 4061 are gathered by the distributing groove 40627 opened at the edge of the concave plate 40625, and are discharged from the distributing groove 40627 at the position of the inclined ramp 40626 due to the centrifugal force generated by the weight of the material following the rotation of the moving convex plate 4061; See also Fig.16 The retaining ring frame 4063 includes a frame ring body 40631, and the frame ring body 40631 is evenly provided with a plurality of discharge grooves 40632 in a radial direction, and a plurality of balls 40633 are evenly provided at the inner edge of the frame ring body 40631 and at the positions corresponding to the annular rotating groove 40616, and the outer diameters of the boss plate 40612 and the concave plate 40625 are equal to the inner diameter of the frame ring body 40631, and the outer diameters of the chassis I 40611 and the chassis II 40621 are smaller than the outer diameter of the frame ring body 40631; The specific implementation method is as follows: the frame ring body 40631 is fixed to the fixed concave plate 4062, and the ball 40633 of the frame ring body 40631 rotates along the annular groove 40616 to ensure that the transmission motor 50 drives the rotation of the movable cam 4061, and the smoothness of the rotation of the movable cam 4061 is ensured, and the retaining ring frame 4063 maintains the lateral relative position of the movable cam 4061 and the fixed concave plate 4062 to avoid disturbance vibration caused by the rotation of the movable cam 4061 and affecting the granulation size.

[0036] Working principle of the present invention: Refer to the instruction manual Figure 1-16 When the disc friction device for recycling fabric fibers provided by the present invention is used, the specific process is as follows: First, the crushed waste and raw materials are added to the outer sleeve 201 from the feeding hopper 203, and the driving motor Ⅰ30 drives the auger core shaft 202 to continuously rotate and transport the materials. The materials are added to the temporary material retention space along the rotation direction of the auger core shaft 202 through the through hole Ⅱ40623. During this period, the tail bearing and the coupling 204 are set to ensure the rotation stability of the auger core shaft 202. The outer sleeve 201 supports the auger core shaft 202, and the pipe holding platform 102 wraps the outer sleeve 201 to maintain stability, thereby effectively avoiding the vibration caused by the transmission of the auger core shaft 202. The material entering the friction mechanism 40 is driven by the driving motor 50 to rotate the movable convex plate 4061. During this period, the retaining ring frame 4063 is arranged to be aligned with the ball 40633 and the annular rotating groove 40616. The retaining ring frame 4063 maintains the relative position of the movable convex plate 4061 and the fixed concave plate 4062, effectively preventing the movable convex plate 4061 from vibrating and slightly misaligning to cause a "knife collision". The movable convex plate 4061 rotates and operates, and the grinding toughness (grinding toughness I 40619 and grinding toughness II 40620) corresponding to the grinding knife I 40615 and the grinding knife II 40624 shears and crushes the material. After that, the high-speed friction between the convex plate 40612 and the concave plate 40625 causes the material to be heated and softened, thereby passing through the dividing trough 4062. The sticky material is gathered at position 7. Under the centrifugal force of the high-speed rotation of the moving convex disc 4061 and the weight of the material, the material is discharged from the friction group accessory 406 through the discharge groove 40632 from the inclined ramp 40626 at the edge of the concave disc 40625, and then gathered at the processing cavity 402. During this period, the driving motor II 603 drives the driving impeller to rotate at high speed to form a negative pressure airflow, which helps the granular material to be discharged from the friction group accessory 406 (negative pressure forms a pulling force), effectively avoiding the situation where the sticky material is retained on the surface of the moving convex disc 4061 and the fixed concave disc 4062 and cannot be discharged smoothly. The granular material gathered in the processing cavity 402 is discharged from the friction mechanism 40 through the discharge hopper 404 with the negative pressure airflow, and then is transported to the material centralized storage place by the finished material extraction component 60; Later, during the use of the device, the inspection door 104 can be opened to perform line maintenance on the equipment, or the shell plate 405 can be removed by removing the bolts, thereby removing the movable cam 4061 from the friction group accessory 406, and the rib grinding knives corresponding to the movable cam 4061 and the fixed concave plate 4062 are removed through the mounting holes, thereby removing and replacing the rib grinding knife I 40615 or the rib grinding knife II 40624, thereby completing the maintenance of the movable cam 4061 or the fixed concave plate 4062.
