Description

Technical Field

[0001] This utility model relates to the field of plastic bottle cap processing technology, specifically to a feeding mechanism for processing plastic bottle caps with dust removal function. Background Technology

[0002] In the processing and production of plastic bottle caps, the feeding mechanism is an essential piece of equipment. Its function is to transport the plastic bottle cap raw materials to the subsequent processing station. Most of the existing feeding mechanisms for plastic bottle cap processing only have basic feeding functions and neglect the treatment of dust and impurities on the surface of the feeding mechanism. These impurities will affect the processing accuracy of the bottle caps. Therefore, it is necessary to use a feeding mechanism for plastic bottle cap processing with dust removal function.

[0003] However, due to the poor feeding and limiting capabilities of the feeding mechanism for plastic bottle cap processing with dust removal function, it is not convenient to limit and feed bottle caps of different diameters according to the feeding needs during actual use. During the conveying process, multiple bottle caps are usually conveyed uniformly by a conveyor belt, which is not convenient for sequential limiting and conveying, affecting the neatness of the bottle caps. As a result, manual sorting is required when conveying them to the next process, which affects the conveying efficiency and increases labor costs. Utility Model Content

[0005] The purpose of this utility model is to provide a feeding mechanism for processing plastic bottle caps with dust removal function, so as to solve the problem mentioned in the background art that the prior art is not convenient for limiting and conveying bottle caps of different diameters according to the feeding needs.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a feeding mechanism for processing plastic bottle caps with dust removal function, including a mounting support plate, a conveyor belt movably mounted in the middle of the mounting support plate, a support frame fixedly mounted at the top of the mounting support plate, a feeding hopper fixedly mounted at the top of the support frame, a PLC controller fixedly mounted on one side of the feeding hopper, and a feeding limit mechanism provided at the top of the conveyor belt;

[0008] The feeding limiting mechanism includes a supporting gantry frame. The supporting gantry frame is fixedly installed on the side of the top of the mounting support plate away from the support frame. A sliding through groove is opened at the top of the supporting gantry frame. A servo motor is fixedly installed on one side of the supporting gantry frame. The servo motor is electrically connected to the PLC controller.

[0009] Preferably, an adjusting screw is fixedly installed on the output shaft end of the servo motor. The adjusting screw extends into the interior of the sliding groove. A supporting movable block is fixedly installed on the inner wall of the sliding groove on the side away from the servo motor. The side of the adjusting screw away from the servo motor is rotatably connected to the supporting movable block. Two positioning screw blocks are threadedly engaged at the outer end of the adjusting screw.

[0010] Preferably, a positioning groove is provided on the side of the supporting gantry away from the hopper, and a supporting limiting slider is fixedly installed on one side of the two positioning screw blocks, and the supporting limiting slider is movably connected inside the positioning groove.

[0011] Preferably, a support connecting rod is fixedly installed at the bottom end of the two positioning screw blocks, and a limit baffle is fixedly installed at the bottom end of the support connecting rod.

[0012] Preferably, a discharge pipe is fixedly installed at the bottom end of the discharge hopper, a plurality of support columns are evenly fixedly installed at the bottom end of the mounting support plate, and a support base plate is fixedly installed at the bottom end of the support columns.

[0013] Preferably, a dust collection box is fixedly installed on one side of the top of the support base plate, a vacuum fan is fixedly installed on the top of the dust collection box, the vacuum fan is electrically connected to the PLC controller, a vacuum pipe is fixedly installed on the top of the vacuum fan, a vacuum head is fixedly installed on the side of the vacuum pipe away from the vacuum fan, a dust conveying pipe is fixedly installed on one side of the vacuum fan, the dust conveying pipe extends into the interior of the dust collection box, an exhaust filter is fixedly installed on the top of the dust collection box, and a door is hinged to one side of the dust collection box.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This feeding mechanism for processing plastic bottle caps with dust removal function effectively solves the problem of limiting the conveying of bottle caps of different diameters by setting a feeding limit mechanism. The PLC controller controls the servo motor to start, and the servo motor drives the adjusting screw to rotate. Since the two positioning screws are engaged with the adjusting screw threads, when the adjusting screw rotates, the two positioning screws can move towards or away from each other along the adjusting screw, thereby driving the support limit slider to slide in the positioning through groove, and at the same time causing the limit baffle to move. Thus, the distance between the two limit baffles can be flexibly adjusted according to the bottle cap diameter, so as to achieve precise limiting of bottle caps of different diameters. During the conveyor belt conveying process, the limit baffle can ensure that the bottle caps are conveyed in an orderly manner in sequence, avoiding mutual squeezing or misalignment, which greatly improves the neatness of bottle cap conveying. When conveying to the next process, no manual sorting is required, which significantly improves the conveying efficiency and reduces labor costs.

[0016] 2. This feeding mechanism for processing plastic bottle caps with dust removal function is electrically connected to a dust extraction fan and a PLC controller. It can be started or stopped according to actual needs. When the dust extraction fan is started, the dust extraction pipe and dust extraction head suck up the dust and impurities on the surface of the conveyor belt and send them into the dust collection box through the dust conveying pipe for collection. This effectively removes the dust and impurities on the surface of the conveyor belt. The exhaust filter prevents dust from leaking out, ensuring a clean working environment and avoiding the impact of dust and impurities on the processing accuracy of bottle caps. It also reduces processing defects caused by impurities and improves the finished product quality and pass rate of plastic bottle caps. Attached Figure Description

[0023] Please see Figures 1-4This utility model provides a technical solution: a feeding mechanism for processing plastic bottle caps with dust removal function, including a mounting support plate 1, a conveyor belt 2 movably mounted in the middle of the mounting support plate 1, a support frame 3 fixedly mounted at the top of the mounting support plate 1, a feeding hopper 4 fixedly mounted at the top of the support frame 3, a PLC controller 5 fixedly mounted on one side of the feeding hopper 4, and a feeding limit mechanism 6 provided at the top of the conveyor belt 2.

[0024] The loading limit mechanism 6 includes a supporting gantry frame 601. The supporting gantry frame 601 is fixedly installed on the side of the top of the mounting support plate 1 away from the supporting frame 3. A sliding groove 602 is opened at the top of the supporting gantry frame 601. A servo motor 603 is fixedly installed on one side of the supporting gantry frame 601. The servo motor 603 is electrically connected to the PLC controller 5. An adjusting screw 604 is fixedly installed on the output shaft end of the servo motor 603. The adjusting screw 604 extends into the interior of the sliding groove 602. A supporting movable block 605 is fixedly installed on the inner wall of the sliding groove 602 on the side away from the servo motor 603. The side of the adjusting screw 604 away from the servo motor 603 is rotatably connected to the supporting movable block 605. The outer end of the adjusting screw 604 is threadedly engaged with two positioning... The screw block 606 has a positioning slot 607 on the side of the gantry frame 601 away from the hopper 4. A support limiting slider 608 is fixedly installed on one side of the two positioning screw blocks 606. The support limiting slider 608 is movably connected inside the positioning slot 607. A support connecting rod 609 is fixedly installed at the bottom end of the two positioning screw blocks 606. A limit baffle 610 is fixedly installed at the bottom end of the support connecting rod 609. When the servo motor 603 is started, the output shaft of the servo motor 603 drives the adjusting screw 604 to rotate. Since the two positioning screw blocks 606 are threadedly engaged with the adjusting screw 604, when the adjusting screw 604 rotates, the two positioning screw blocks 606 will move towards or away from each other along the adjusting screw 604. When the positioning screw blocks 606 move, they also drive the limit baffle 610 to move.

[0025] A feeding pipe 7 is fixedly installed at the bottom of the feeding hopper 4. Several support columns 8 are evenly fixedly installed at the bottom of the mounting support plate 1. A support base plate 9 is fixedly installed at the bottom of the support columns 8. A dust collection box 10 is fixedly installed on one side of the top of the support base plate 9. A dust collection fan 11 is fixedly installed at the top of the dust collection box 10. The dust collection fan 11 is electrically connected to the PLC controller 5. A suction pipe 12 is fixedly installed at the top of the dust collection fan 11. A suction head 13 is fixedly installed on the side of the suction pipe 12 away from the dust collection fan 11. A dust conveying pipe 14 is fixedly installed on one side of the vacuum blower 11, extending into the interior of the dust collection box 10. An exhaust filter 15 is fixedly installed on the top of the dust collection box 10. A door 16 is connected to one side of the dust collection box 10 via a hinge. When the vacuum blower 11 is started, it generates suction. The vacuum head 13 located on one side of the conveyor belt 2 sucks in the dust and impurities on the surface of the conveyor belt 2. The dust and impurities enter the vacuum blower 11 through the vacuum pipe 12 and are then transported to the dust collection box 10 for collection by the dust conveying pipe 14.

[0026] Working Principle: When feeding bottle caps, first, place the device stably in the desired location. Connect an external power supply to power the equipment. Based on the diameter of the plastic bottle caps to be processed, set the operating parameters of the servo motor 603 via the PLC controller 5. The PLC controller 5 then sends a command to start the servo motor 603. The output shaft of the servo motor 603 drives the adjusting screw 604 to rotate. Because the two positioning screws 606 are threadedly engaged with the adjusting screw 604, when the adjusting screw 604 rotates, the two positioning screws 606... The positioning screw 606 moves in opposite directions along the adjusting screw 604. Simultaneously, the positioning screw block 606 moves, causing the support limiting slider 608 to slide within the positioning through groove 607, thus ensuring the stability of the positioning screw block 606's movement. The positioning screw block 606 also drives the limiting baffle 610 to move via the support connecting rod 609 until the distance between the two limiting baffles 610 is adjusted to a suitable size for the current bottle cap diameter, completing the adjustment of the feeding limiting mechanism 6. Then, the plastic bottle cap raw material is poured into the feeding hopper 4, and the bottle caps fall onto the conveyor belt 2 through the feeding pipe 7. At this time, the conveyor belt is started. 2. Start the conveyor belt 2 to transport the bottle caps along the conveyor belt 2 to the subsequent processing station. The conveyor belt 2 is a BD-500 type belt conveyor. During the conveying process, the limiting baffle 610 located above the conveyor belt 2 limits the bottle caps, ensuring that the bottle caps move sequentially and orderly on the conveyor belt 2, avoiding mutual squeezing, misalignment, etc., and achieving precise limiting conveying. When the conveyor belt 2 is running, the dust collection fan 11 is started by the PLC controller 5 according to actual needs. The dust collection fan 11 generates suction, and the dust collection head 13 located on one side of the conveyor belt 2 draws the contents of the conveyor belt into the dust collection fan. Dust and impurities on the surface of conveyor belt 2 are sucked in and enter the dust collection fan 11 through the dust suction pipe 12. They are then transported to the dust collection box 10 by the dust conveying pipe 14. The exhaust filter 15 at the top of the dust collection box 10 can effectively filter the exhaust air, prevent dust leakage, and ensure a clean working environment. At the same time, it continuously removes dust from the conveyor belt 2 to prevent dust and impurities from affecting the processing accuracy of the bottle caps. The dust collection fan 11 is a model 11DF-11-2.2. The box door 16 can be opened later as needed to clean the impurities in the dust collection box 10 for continued use.
