Description

Technical Field

[0001] This utility model relates to the field of tape production technology, and more specifically, to an extruder reinforced feeder. Background Technology

[0002] Adhesive tape is a strip-shaped material used for bonding and fixing, mainly composed of two parts: a substrate and an adhesive. The substrate, acting as the tape's skeleton and carrier, determines its physical properties; the adhesive, on the other hand, gives the tape its adhesive properties and is the core of its function. The main raw material for ordinary transparent tape is polypropylene granules, and its production process is as follows: Polypropylene granules are first heated and melted in an extruder, then extruded into a film through a die. The extruded film is then cooled and cured using cooling rollers or a water bath. To improve the film's mechanical properties, it is usually stretched longitudinally or laterally. Subsequently, adhesive is applied to one or both sides of the film, and it is then dried and cured in an oven or with hot air. Finally, the dried film is slit into tapes of specific widths and wound into rolls.

[0003] In the initial stage of tape production, namely the extrusion process, traditional extruders use simple feeders, mostly ordinary hoppers, which are prone to material residue. Furthermore, polypropylene granules may contain impurities or absorb moisture; if they are not adequately dried and cleaned during the feeding process, the final tape quality will be severely affected.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes an extruder reinforced feeder to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows: An extruder-enhanced feeder includes: a feeder housing; a control panel disposed on the outside of the feeder housing; a first motor disposed at the bottom center of the feeder housing; a rotating plate disposed at the top of the output end of the first motor and cooperating with the feeder housing; a screen disposed at the top of the rotating plate, with both sides of the top of the screen connected to the feeder housing via locking mechanisms; a limiting discharge channel disposed at the top of the rotating plate for connecting to the extruder; a feed cylinder fixedly disposed inside the screen; and a feeding mechanism disposed at the top of the feed cylinder for assisting in the feeding of polypropylene granules.

[0007] Furthermore, to improve the ease of operation of the feeder and the efficiency of equipment operation, handles are symmetrically provided at the top of the screen; an air inlet pipe and a feed port are provided at the top of the feed cylinder.

[0008] Furthermore, in order for the rotating plate to stably drive the polypropylene particles to rotate under the combined action of the limiting slide and the limiting ring, thereby generating centrifugal force, a limiting slide that cooperates with the rotating plate is provided in the inner middle of the feeder housing; a limiting ring that cooperates with the limiting slide is provided on the outer side of the rotating plate.

[0009] Furthermore, to facilitate easy disassembly and replacement of the screen and feeder housing, and to prevent impurities in the polypropylene granules from entering the extruder and damaging the screw and barrel, the locking mechanism includes a first mounting shell located at the top of the screen. Inside the first mounting shell is a first spring, and inside the first spring is a pressing post. Symmetrically arranged on the outer side of the pressing post are first limiting rings that cooperate with the first mounting shell. One end of the pressing post is provided with a limiting ring, and a disc ring is arranged between the limiting ring and the first limiting ring. Symmetrically arranged between the disc ring and the limiting ring are locking blocks. One side of the locking block is provided with a fixing post, and a second spring is sleeved on the outer side of the fixing post. One end of the second spring is provided with a second limiting ring. A second mounting shell that cooperates with the feeder housing is located outside the second limiting ring. The locking block has a conical structure and cooperates with the disc ring.

[0010] Furthermore, in order to allow the polypropylene granules to be fed into the extruder along the arc-shaped discharge section and the straight discharge section under the action of centrifugal force, the limiting discharge channel is composed of an arc-shaped discharge section and a straight discharge section.

[0011] Furthermore, in order to feed the polypropylene granules into the feeder housing and make the hot air contact the polypropylene granules more evenly, ensuring the dehumidification effect of the polypropylene granules and improving the quality of the conveyor belt, the feeding mechanism includes a second motor located at the middle of the top of the feed cylinder. The output end of the second motor is connected to a rotating rod through the top of the feed cylinder. Several stirring rods are staggered on the top of the rotating rod, and an auger is installed at the bottom of the rotating rod.

[0012] The beneficial effects of this utility model are as follows: 1) With the combined action of the rotating plate, screen, locking mechanism, limiting discharge channel, feeding cylinder, feeding mechanism and air inlet pipe, this utility model can easily disassemble the screen, realize the full drying and impurity removal of polypropylene particles during the feeding process, and smoothly introduce all polypropylene particles into the extruder with the help of centrifugal force, effectively prevent material residue, and improve the product quality and raw material utilization efficiency of the tape.

[0013] 2) With the combined action of the rotating plate, the limiting discharge channel, the feeding cylinder, the feeding mechanism and the air inlet pipe, the polypropylene particles are fully dried and impurities are removed during the feeding process. The centrifugal force is used to smoothly guide all the polypropylene particles into the extruder, effectively preventing material residue and improving the product quality and raw material utilization efficiency of the tape.

[0014] 3) With the cooperation of the screen and the locking mechanism, the screen and the feeder housing can be easily disassembled and replaced. The screen intercepts impurities in the polypropylene particles, preventing them from entering the extruder and damaging the screw and barrel of the extruder. Attached Figure Description

[0018] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0019] According to an embodiment of the present invention, an extruder reinforced feeder is provided.

[0020] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-4 As shown, the extruder reinforced feeder according to an embodiment of the present invention includes: a feeder housing 1; a control panel 2 disposed on the outside of the feeder housing 1; a first motor 3 disposed at the bottom center of the feeder housing 1; a rotating plate 4 disposed at the top of the output end of the first motor 3 and cooperating with the feeder housing 1; a screen 5 disposed at the top of the rotating plate 4, with the top two sides of the screen 5 connected to the feeder housing 1 by a locking mechanism 6; a limiting discharge channel 7 disposed at the top of the rotating plate 4 for connecting to the extruder; a feed cylinder 8 fixedly disposed inside the screen 5; and a feeding mechanism 9 disposed at the top of the feed cylinder 8 for assisting in the feeding of polypropylene granules.

[0021] It should be explained that in practical applications, the bottom end of the limiting discharge channel 7 is connected to the extruder. The extruder is a device used to heat and melt materials such as plastics and rubber and extrude them through a die. The extruder consists of a hopper, screw, barrel, heating and cooling system, drive system, die, control system, and cooling and shaping device. The hopper is used to store and transport the raw material granules or powder to be processed, and is usually located at the top of the extruder (where it can be connected to the bottom end of the limiting discharge channel 7). The screw is located inside the barrel and is the core component of the extruder. When the screw rotates, it transports the raw material forward and heats, plasticizes, and mixes it in the process. The barrel... The barrel is a cylindrical body surrounding the screw, typically equipped with heating and cooling devices to control the temperature of the processed material; the heating and cooling system regulates the temperature of the barrel to ensure that the material is plasticized and extruded at the appropriate temperature; the drive system includes an electric motor and a reducer to drive the screw to rotate, providing the power required for extrusion; the die is connected at the barrel outlet to extrude the molten material into a specific shape or cross-section; the control system includes various instruments and controllers to monitor and regulate parameters such as temperature, pressure, and speed during the extrusion process; and the cooling and shaping device cools and shapes the extruded material, ensuring it maintains the desired shape after solidification.

[0022] With the assistance of the above-mentioned technical solution of this utility model, the rotating plate 4, screen 5, locking mechanism 6, limiting discharge channel 7, feeding cylinder 8, feeding mechanism 9, and air inlet pipe 11 work together to easily disassemble the screen 5, achieving thorough drying and impurity removal of polypropylene particles during the feeding process. Centrifugal force is then used to smoothly guide all polypropylene particles into the extruder, effectively preventing material residue and improving the product quality and raw material utilization efficiency of the conveyor belt. The rotating plate 4, limiting discharge channel 7, feeding cylinder 8, and feeding mechanism 11 are all part of this utility model. With the combined action of the structure 9 and the air inlet pipe 11, the polypropylene granules are thoroughly dried and impurities are removed during the feeding process. Centrifugal force is used to smoothly guide all polypropylene granules into the extruder, effectively preventing material residue and improving the product quality and raw material utilization efficiency of the conveyor belt. With the combined action of the screen 5 and the locking mechanism 6, the screen 5 and the feeder housing 1 can be easily disassembled and replaced. The screen 5 intercepts impurities in the polypropylene granules, preventing impurities from entering the extruder and damaging the screw and barrel of the extruder.

[0023] In one embodiment, for the screen 5 and the feed cylinder 8, the top of the screen 5 is symmetrically provided with a handle 10; the top of the feed cylinder 8 is provided with an air inlet pipe 11 and a feed inlet 12, thereby improving the ease of operation of the feeder and the operating efficiency of the equipment.

[0024] It should be explained that, in specific applications, hot air needs to be introduced into one end of the air inlet pipe 11 to dehumidify the polypropylene particles and prevent it from affecting the quality of subsequent tape production.

[0025] In one embodiment, for the feeder housing 1 and the rotating plate 4, a limiting slide 13 that cooperates with the rotating plate 4 is provided in the middle of the feeder housing 1; a limiting ring 14 that cooperates with the limiting slide 13 is provided on the outer side of the rotating plate 4. Thus, under the cooperation of the limiting slide 13 and the limiting ring 14, the rotating plate 4 can stably drive the polypropylene particles to rotate, thereby generating centrifugal force.

[0026] In one embodiment, the locking mechanism 6 includes a first mounting shell 601 disposed at the top of the screen 5. A first spring 602 is disposed inside the first mounting shell 601. A pressing post 603 is disposed inside the first spring 602. A first limiting ring 604, which cooperates with the first mounting shell 601, is symmetrically disposed on the outer side of the pressing post 603. A limiting ring 605 is disposed at one end of the pressing post 603. A flying saucer ring 606 is disposed between the limiting ring 605 and the first limiting ring 604. A locking mechanism is symmetrically disposed between the flying saucer ring 606 and the limiting ring 605. Block 607 has a fixing post 608 on one side, and a second spring 609 is sleeved on the outside of the fixing post 608. A second limiting ring 610 is provided at one end of the second spring 609. A second mounting shell 611 that cooperates with the feeder housing 1 is provided on the outside of the second limiting ring 610. Block 607 has a conical structure and cooperates with the flying saucer ring 606, so that the screen 5 and the feeder housing 1 can be easily disassembled and replaced. The screen 5 intercepts impurities in the polypropylene particles and prevents impurities from entering the extruder and damaging the screw and barrel of the extruder.

[0027] Working principle of locking mechanism 6: When screen 5 and feed cylinder 8 need to be fixed, the operator pushes the pressing column 603. The pressing column 603 moves inside the first mounting shell 601. The pressing column 603 drives the limiting ring 605 and the flying saucer ring 606 to move forward and squeeze the first spring 602. When the limiting ring 605 moves forward, it simultaneously squeezes the locking blocks 607 on both sides to move outward. Under the limiting action of the second limiting ring 610 and the second mounting shell 611, the locking blocks 607 move outward steadily. The outward movement of the locking blocks 607 squeezes the second spring 609 to compress backward until it enters between the flying saucer ring 606 and the limiting ring 605. Under the action of the elastic force of the second limiting ring 610, the locking blocks 607 reset and are locked between the flying saucer ring 409 and the limiting ring 408, thus locking and fixing the screen 5 and the feeder shell 1. When the screen 5 and feed cylinder 8 need to be cleaned and disassembled, the operator pushes the pressing column 603 again. The pressing column 603 moves inside the first mounting shell 601, and the pressing column 603 drives the limiting ring 605 and the flying saucer ring 606 to move forward. At the same time, it squeezes the locking blocks 607 on both sides to move outward. Under the limiting action of the second limiting ring 610 and the second mounting shell 611, the locking blocks 607 move outward steadily. At the same time, the locking blocks 607 slide outside the flying saucer ring 606 and disengage from the limiting ring 605 and the flying saucer ring 606. At this time, the locking blocks 607 move outward and squeeze the second spring 609 to compress backward. When the pressing column 603 resets under the elastic force of the first spring 602, the locking blocks 410 slide along the limiting ring 605 and the flying saucer ring 606 and reset under the elastic force of the second spring 609, releasing the locking of the screen 5 and the feeder housing 1.

[0028] In one embodiment, the limiting discharge channel 7 is composed of an arc-shaped discharge section 701 and a straight discharge section 702, so that polypropylene particles can be introduced into the extruder along the arc-shaped discharge section 701 and the straight discharge section 702 under the action of centrifugal force.

[0029] In one embodiment, the feeding mechanism 9 includes a second motor 901 located at the top center of the feeding cylinder 8. The output end of the second motor 901 passes through the top of the feeding cylinder 8 and is provided with a rotating rod 902. Several stirring rods 903 are staggered on the top of the rotating rod 902, and an auger 904 is provided at the bottom of the rotating rod 902. This allows polypropylene particles to enter the feeder housing 1, making the hot air contact the polypropylene particles more evenly, ensuring the dehumidification effect of the polypropylene particles, and improving the quality of the tape production.

[0030] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0031] In practical application, the operator first introduces hot air into one end of the air inlet pipe 11, then feeds polypropylene granules into the feed port 12. Under the control panel 2, the second motor 902 is controlled and started. The output of the second motor 902 drives the rotating rod 902 to rotate, which in turn drives the stirring rod 903 and the auger 904 to rotate. The stirring rod 903 makes the hot air and polypropylene granules mix more evenly, and the auger 904 conveys the polypropylene granules into the feeder housing 1. Under the control panel 2, the first motor 3 is controlled and started. The output of the first motor 3 drives the rotating plate 4 to rotate. The rotation of the rotating plate 4 generates centrifugal force, throwing out the polypropylene granules. The screen 5 filters the polypropylene granules and intercepts the polypropylene particles. Impurities in the granules and qualified polypropylene granules enter the gap between the screen 5 and the feeder housing 1. Under the continuous action of centrifugal force, the polypropylene granules are fed into the extruder along the arc-shaped discharge section 701 and the straight discharge section 702. At the same time, when the internal space of the filter screen needs to be cleaned, the operator pushes the pressing column 603 to release the lock between the screen 5 and the feeder housing 1, and pulls the handles 10 on both sides of the top of the screen 5 to remove the screen 5 and the feed cylinder 8 with the help of tools. After cleaning, the screen 5 and the feed cylinder 8 are lowered by using the handles 10 on both sides of the top of the screen 5, aligned with the first mounting shell 601 and the second mounting shell 611, and the pressing column 603 is pushed again to lock the screen 5 and the feeder housing 1 (the working principle of the locking mechanism 6 is as described above).

[0032] In summary, by utilizing the above-mentioned technical solution of this utility model, the rotating plate 4, screen 5, locking mechanism 6, limiting discharge channel 7, feeding cylinder 8, feeding mechanism 9, and air inlet pipe 11 work together to easily disassemble the screen 5, achieving thorough drying and impurity removal of polypropylene particles during the feeding process. Furthermore, centrifugal force smoothly guides all polypropylene particles into the extruder, effectively preventing material residue and improving the product quality and raw material utilization efficiency of the conveyor belt. The rotating plate 4, limiting discharge channel 7, feeding cylinder 8, and air inlet pipe 11 work together to achieve this. With the combined action of the feeding mechanism 9 and the air inlet pipe 11, the polypropylene granules are thoroughly dried and impurities are removed during the feeding process. Centrifugal force is used to smoothly guide all polypropylene granules into the extruder, effectively preventing material residue and improving the product quality and raw material utilization efficiency of the conveyor belt. With the combined action of the screen 5 and the locking mechanism 6, the screen 5 and the feeder housing 1 can be easily disassembled and replaced. The screen 5 intercepts impurities in the polypropylene granules, preventing impurities from entering the extruder and damaging the screw and barrel of the extruder.
