Abstract
Description
Technical Field
[0001] This invention relates to the field of MPP pipe feeding and processing technology, and more specifically, to an automatic feeding system for MPP pipe production. Background Technology
[0002] MPP pipe is a new type of pipe made of polypropylene as the base material and modified by adding heat-resistant and pressure-resistant modifiers. It is widely used in power, municipal, and agricultural fields.
[0003] For example, an automatic pipe feeding device with announcement number CN220787194U uses a downwardly inclined section and a height limiting structure set above the inclined section to make the pipe roll down the inclined section in an orderly manner. The lifting mechanism pushes the pipe that is in contact with the stop block away from the inclined section. After the pipe is freed from the block, it falls into the horizontal conveying device, thus realizing the orderly feeding of the pipe.
[0004] However, longer and heavier MPP pipes are prone to shifting during transportation, leading to processing misalignment or equipment jamming, which seriously affects production efficiency and product quality.
[0005] Furthermore, if the slope design is improper during the transport and descent of MPP pipes, excessive speed can easily lead to severe impacts. It is impossible to dynamically adjust the descent slope of MPP pipes to avoid surface wear or internal structural damage, thereby improving product quality and service life. Therefore, a solution is provided. Summary of the Invention
[0006] To overcome the above-mentioned defects of the prior art, the present invention provides an automatic feeding system for MPP pipe production.
[0007] To achieve the above objectives, the present invention provides the following technical solution: an automatic feeding system for MPP pipe production, comprising a feeding rack and multiple sets of conveyors arranged in an array sliding above it, wherein a dynamic guide plate is rotatably provided on the output side of the conveyor, the multiple sets of dynamic guide plates are fixedly connected by a connecting rod, a fixed guide plate is provided on the output side of the dynamic guide plate, and an upper limit plate is provided above the multiple sets of fixed guide plates, and the upper limit plate is parallel to the fixed guide plate;
[0008] The conveyor has a movable groove inside, and multiple movable grooves are provided with connecting long rods 2 inside. Eccentric wheels 1 are fixedly installed on both sides of the connecting long rods 2. An adjustment plate is connected above the eccentric wheels 1. One end of the adjustment plate is connected to the connecting long rod 1, and the other end of the adjustment plate is rotatably connected to the feeding frame.
[0009] Anti-deviation components are installed between the multiple sets of conveyors to prevent the MPP pipe from deviating during transport.
[0010] Furthermore, the anti-deviation component includes fixed blocks fixedly installed at both ends of the connecting rod II. Movable columns are fixedly installed on both sides of the fixed blocks. Positioning sleeves are slidably fitted on the outer side of the movable columns, and the bottom of the positioning sleeves is fixedly connected to the feeding frame. A thrust spring I is fitted on the outer side of the movable columns.
[0011] Furthermore, a cross plate is fixedly installed on the outer wall between the two sets of conveyors on the second connecting rod. A matching sliding plate is slidably installed on the side wall of the second connecting rod near the conveyor. A T-shaped groove is opened on the side wall of the conveyor near the matching sliding plate. The matching sliding plate slides with the T-shaped groove through the T-shaped plate, and a thrust spring is installed between the T-shaped plate and the T-shaped groove.
[0012] Furthermore, an eccentric wheel is provided on one side of the sliding plate, and the eccentric wheel is fixedly connected to the drive shaft inside the conveyor.
[0013] Furthermore, the feed rack is provided with a set of guide rollers for conveying MPP pipes on the top wall of the fixed guide plate output side.
[0014] Furthermore, bottom mounting blocks are provided on both sides of the bottom of the conveyor, and two sets of slide rails are provided above the feeding rack. The bottom mounting blocks slide in cooperation with their corresponding slide rails, and a motor is installed on the side wall of the feeding rack.
[0015] Furthermore, a threaded rod is threadedly connected to the outer wall of one of the bottom mounting blocks, and multiple sets of threaded rods are fixedly connected by a connecting long shaft. The connecting long shaft closer to the motor is fixedly connected to the output end of the motor, and the connecting long shaft further away from the motor is rotatably engaged with the feeding frame.
[0016] Furthermore, the fixed guide plate is fixedly connected to the side wall of the conveyor, and the upper limit plate is fixedly connected to the feeding frame through multiple sets of cylinders.
[0017] The technical effects and advantages of this invention are as follows:
[0018] 1. This invention uses a drive shaft inside the conveyor to drive an eccentric wheel two to rotate. The eccentric wheel two continuously engages with the sliding plate, and the thrust spring two continuously provides thrust to the sliding plate, causing the connecting rod three to reciprocate within the movable groove, thereby achieving the reciprocating vibration of the cross plate. When the conveyor transports the material to the top of the cross plate, multiple sets of cross plates vibrate synchronously to regulate the MPP pipe, ensuring that the MPP pipe maintains the correct direction and position during the transport process, reducing processing misalignment or equipment jamming caused by offset, and improving production efficiency and product quality.
[0019] 2. In this invention, the connecting rod 2 is intermittently rotated by motor 2. When the cross plate rotates 90 degrees, the MPP pipe with the adjusted position is conveyed. When the MPP pipe moves along the output side of the conveyor to the top of the dynamic guide plate, the cross plate rotates one revolution to adjust the position of the next MPP pipe. At this time, the eccentric wheel 1 pushes the adjustment plate upward so that the outer wall of the MPP pipe abuts against the upper limit plate. Then, as the next MPP pipe is conveyed, the connecting rod 2 rotates one revolution again, and the eccentric wheel 1 rotates one revolution.
[0020] Furthermore, when the eccentric wheel pushes the control plate upward, the end of the dynamic guide plate moves downward and contacts the top of the fixed guide plate. The MPP pipe is conveyed along the gap between the upper limit plate and the fixed guide plate to the two guide rollers for subsequent processing. The design of the slope being small at the beginning and large at the end allows the MPP pipe to accelerate smoothly in the initial stage, avoiding the pipe jumping, jamming or deviating from the track during the conveying process due to the slope being too large, thus ensuring the continuity and stability of the conveying process.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0030] Example 1: Please refer to Figures 1-7 As shown, the problem that the existing technology cannot dynamically adjust the drop slope of MPP pipes to avoid surface wear or internal structural damage, thereby improving product quality and service life, can be solved by the following solution;
[0031] An automatic feeding system for MPP pipe production in this embodiment includes a feeding rack 1 and multiple sets of conveyors 2 arranged in an array and sliding above it. A dynamic guide plate 61 is rotatably provided on the output side of the conveyor 2. The multiple sets of dynamic guide plates 61 are fixedly connected to each other by a connecting rod 63. A fixed guide plate 62 is provided on the output side of the dynamic guide plate 61. The fixed guide plate 62 is fixedly connected to the side wall of the conveyor 2. An upper limit plate 3 is provided above the multiple sets of fixed guide plates 62. The upper limit plate 3 is parallel to the fixed guide plates 62. The upper limit plate 3 is fixedly connected to the feeding rack 1 by multiple sets of cylinders 4.
[0032] It should be noted that: a rubber pad is provided on the side wall of the upper limit plate 3 near the conveyor 2; the conveyor 2 is a functional device for conveying MPP pipes in the prior art, and will not be elaborated on here.
[0033] The conveyor 2 has a movable groove 25 inside. Multiple movable grooves 25 are provided with connecting rods 73 inside. Eccentric wheels 65 are fixed on both sides of the connecting rods 73. A control plate 64 is connected above the eccentric wheels 65. One end of the control plate 64 is connected to the connecting rod 63, and the other end of the control plate 64 is rotatably connected to the feeder 1.
[0034] The dynamic guide plate 61 and the design of a slope that gradually increases slow down the initial falling speed of the MPP pipe, avoid violent impact, reduce the risk of surface wear and internal structural damage to the MPP pipe, and the use of a smaller slope at the beginning of the conveying stage can effectively slow down the initial falling speed of the MPP pipe, avoid violent impact caused by excessive speed, thereby reducing the risk of surface wear or internal structural damage to the MPP pipe and extending its service life.
[0035] Example 2: Please refer to Figures 1-7As shown, the following solutions can be used to address the problem that long and heavy MPP pipes are prone to shifting during transportation, leading to processing misalignment or equipment jamming, which seriously affects production efficiency and product quality.
[0036] An anti-deviation component is provided between multiple sets of conveyors 2 to prevent the MPP pipe from deviating during transport. The anti-deviation component includes a fixed block 71 fixedly installed at both ends of the connecting long rod 2 73. Movable columns are fixedly installed on both sides of the fixed block 71. A positioning sleeve 72 is slidably sleeved on the outside of the movable column, and the bottom of the positioning sleeve 72 is fixedly connected to the feeding rack 1. A thrust spring 1 is sleeved on the outside of the movable column.
[0037] A cross plate 74 is fixedly installed on the outer wall of the connecting rod 2 73 between the two sets of conveyors 2. A matching sliding plate 75 is slidably installed on the side wall of the connecting rod 2 73 near the conveyor 2. A T-shaped groove is opened on the side wall of the conveyor 2 near the matching sliding plate 75. The matching sliding plate 75 slides with the T-shaped plate through the T-shaped plate and the T-shaped groove. A thrust spring 2 is installed between the T-shaped plate and the T-shaped groove.
[0038] It should be noted that: a motor is fixedly installed at the end of the connecting rod 73, and the motor is fixedly connected to the fixing block 71;
[0039] An eccentric wheel 76 is provided on one side of the sliding plate 75, and the eccentric wheel 76 is fixedly connected to the drive shaft inside the conveyor 2.
[0040] The drive shaft inside the conveyor 2 drives the eccentric wheel 76 to rotate. The eccentric wheel 76 continuously engages with the sliding plate 75. The thrust spring 2 continuously provides thrust to the sliding plate 75, causing the connecting rod 3 to move back and forth in the movable groove 25, thereby realizing the reciprocating vibration of the cross plate 74.
[0041] The feed rack 1 is located on the top wall of the fixed guide plate 62, where a set of guide rollers 5 for conveying MPP pipes is inclinedly installed.
[0042] Both sides of the bottom of the conveyor 2 are provided with bottom mounting blocks 21. Two sets of movable slide rails 23 are provided above the feeding rack 1. The bottom mounting blocks 21 and their corresponding movable slide rails 23 are slidably engaged. A motor 24 is installed on the side wall of the feeding rack 1. A threaded rod 22 is threadedly connected to the outer wall of one set of bottom mounting blocks 21. Multiple sets of threaded rods 22 are fixedly connected by a connecting long shaft 26. The connecting long shaft 26 closer to the motor 24 is fixedly connected to the output end of the motor 24, and the connecting long shaft 26 farther away from the motor 24 is rotatably engaged with the feeding rack 1.
[0043] It should be further explained that: the control motor 24 drives the connecting long shaft 26 to rotate, the multiple sets of threaded rods 22 rotate, the threaded rods 22 drive the bottom mounting block 21 to rotate, thereby realizing the displacement of the bottom mounting block 21, and thus adjusting the distance between the conveyors 2. According to the length of the MPP pipe, the distance between the multiple sets of conveyors 2 is adjusted to ensure the stable transportation of the MPP pipe.
[0044] As can be seen from Embodiments 1 and 2 of this invention:
[0045] Through the synchronous vibration design of the anti-deviation component and the cross plate 74, the correct direction and position of the MPP pipe during the conveying process are effectively ensured, reducing processing misalignment and equipment jamming caused by deviation, improving production efficiency and product quality. Secondly, the dynamic guide plate 61 and the slope design of small to large at the beginning slow down the initial falling speed of the MPP pipe, avoid violent impact, and reduce the risk of surface wear and internal structural damage to the MPP pipe.
[0046] Working principle:
[0047] First, the MPP pipe is fed onto multiple sets of parallel conveyors 2. When the conveyors 2 transport the pipe to the top of the cross plate 74, the multiple sets of cross plates 74 vibrate synchronously to regulate the MPP pipe, ensuring that the MPP pipe maintains the correct direction and position during the transport process, reducing processing misalignment or equipment jamming caused by deviation, and improving production efficiency and product quality.
[0048] The principle of achieving the vibration of the cross plate 74 is as follows: the drive shaft inside the conveyor 2 drives the eccentric wheel 76 to rotate, the eccentric wheel 76 continuously engages with the sliding plate 75, and the thrust spring 2 continuously provides thrust to the sliding plate 75, causing the connecting rod 3 to move back and forth in the movable groove 25, thereby achieving the reciprocating vibration of the cross plate 74.
[0049] Motor 2 controls the intermittent rotation of connecting rod 73. When cross plate 74 rotates 90 degrees, the MPP pipe that has been adjusted in position is conveyed. When the MPP pipe moves along the output side of conveyor 2 above the dynamic guide plate 61, cross plate 74 rotates exactly one revolution, that is, rotates another 270 degrees to adjust the position of the next MPP pipe. At the same time, eccentric wheel 65 resets and pushes the control plate 64 upward, and connecting rod 63 moves upward. At this time, the gap between the fixed guide plate 62 and the upper limit plate 3 is smaller than the diameter of the MPP pipe, so that the outer wall of the MPP pipe abuts against the upper limit plate 3.
[0050] As the next MPP pipe is conveyed, the connecting rod 73 rotates once more, the eccentric wheel 65 rotates once, and when the eccentric wheel 65 does not push the control plate 64 upward, the end of the dynamic guide plate 61 moves downward and contacts the top of the fixed guide plate 62. The MPP pipe is conveyed along the gap between the upper limit plate 3 and the fixed guide plate 62 to the two guide roller groups 5 for subsequent processing. At this time, the gap between the fixed guide plate 62 and the upper limit plate 3 is greater than the diameter of the MPP pipe, and the next MPP pipe is blocked by the upper limit plate 3 again. The feeding of the MPP pipe is completed according to the above steps.
[0051] Using a smaller slope at the beginning of the conveying process can effectively slow down the initial descent speed of the pipe, avoid violent impact caused by excessive speed, thereby reducing the risk of surface wear or internal structural damage to the pipe and extending its service life. In addition, the design of a slope that gradually increases from small to large can make the MPP pipe accelerate smoothly in the initial stage, avoiding situations where the pipe jumps, gets stuck or deviates from the track during the conveying process due to an excessive slope, thus ensuring the continuity and stability of the conveying process.
[0052] Obviously, many modifications and variations can be made based on the content of this specification. These embodiments have been selected and specifically described in this specification to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention. The invention is limited only by the claims and their full scope and equivalents.
