Description

Technical Field

[0001] This utility model relates to the technical field of automatic corrugated pipe feeding and lifting machines, and in particular to automatic corrugated pipe feeding and lifting machines. Background Technology

[0002] Traditional automatic nylon corrugated pipe lifting and feeding machines suffer from three core problems due to their simple structure and simplistic control logic: multiple pipe feeding, missing detection, and unstable material supply. Although the industry has attempted to optimize through mechanical improvements or control upgrades, none have achieved coordinated control of dynamic stripping, closed-loop detection, and adaptive adjustment. Specifically, during the lifting process, the multiple layers of material stored in the hopper may cause multiple pipes to be fed at once, leading to malfunctions. Furthermore, the inability to determine whether there is material at the secondary stage results in either overfeeding or empty feeding.

[0003] Therefore, we propose an automatic corrugated pipe feeding and lifting machine to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an automatic corrugated pipe feeding and lifting machine. When using this machine, an additional feeding baffle is added to remove excess material from the first-stage lifting. The correct baffle height is determined by a position sensor of the first-stage lifting cylinder. When the last piece of material arrives, the baffle automatically opens, ensuring that one piece of material is lifted from the first stage to the second-stage hopper. A material availability switch in the second stage detects whether there is material. If there is no material, the first stage repeats the feeding process until there is material in the second-stage hopper, thus ensuring that there is material during the second-stage lifting and guaranteeing a stable material supply from the feeding mechanism, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The automatic corrugated pipe feeding and lifting machine includes a storage bin, a secondary bin, a primary lifting mechanism, and a secondary lifting mechanism. The primary lifting mechanism is divided into upper and lower layers: the lower layer is the area to be lifted, and the upper layer is a buffer isolation area. The tilt angle is 15°. The primary lifting mechanism includes a primary lifting cylinder, a primary lifting plate, and a position sensor. The primary lifting cylinder drives the primary lifting plate to rise and fall through a piston rod. The position sensor is installed at the end of the piston rod and connected to a PLC controller. A primary feeding baffle is provided on the side wall of the storage bin. This primary feeding baffle is opened and closed by a gear and rack mechanism driven by a servo motor and is linked to the position sensor signal to remove excess pipe material.

[0007] The secondary hopper includes a secondary material presence / absence switch, a secondary feeding baffle, and a secondary lifting plate. The secondary material presence / absence switch is installed above the secondary hopper inlet and is used to detect the hopper status. The secondary lifting mechanism includes a secondary lifting cylinder and a secondary lifting plate. The secondary lifting cylinder drives the secondary lifting plate to rise and fall, and is linked to the signal of the secondary material presence / absence switch. A feeding length adjustment plate is provided at the outlet of the storage hopper and is fixed by bolts to support length adjustment. The primary lifting mechanism and the secondary hopper are linked by the baffle to form a closed-loop feeding system.

[0008] In a further embodiment, the position sensor is a magnetic proximity switch with a detection accuracy of ±0.5mm, and is installed on the side wall of the first-stage lifting plate.

[0009] In a further embodiment, the primary feeding baffle is made of stainless steel with a polished surface, and has an opening angle of 0° to 90° and an opening speed of 0.2 seconds per cycle.

[0010] In a further embodiment, the secondary material presence / absence switch is a photoelectric reflective sensor, installed at a height of 10cm above the secondary material hopper inlet, with a detection response time ≤0.5 seconds.

[0011] In a further embodiment, the feeding length adjustment plate supports manual adjustment, with an adjustment range of 500mm-1500mm.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, when using the corrugated pipe automatic feeding elevator, an additional feeding baffle is added to remove excess material from the first-stage lifting. The correct material blocking height is determined by the position sensor of the first-stage lifting cylinder. When the last piece of material arrives, the baffle automatically opens, ensuring that one piece of material is lifted from the first stage to the second-stage hopper. A material availability switch in the second stage detects whether there is material. If there is no material, the first stage repeats feeding until there is material in the second-stage hopper, thus ensuring that there is material during the second-stage lifting and guaranteeing a stable material supply from the feeding mechanism.

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-2The corrugated pipe automatic feeding and lifting machine includes a storage bin 8. The feeding length adjustment plate 2 is located at the outlet of the storage bin 8 and is bolted to the frame, parallel to the primary lifting plate 9. The position of the bolts can be adjusted manually by a knob to change the plate spacing, preventing excessively long pipes from getting stuck or excessively short pipes from slipping. A position sensor 1 is fixed to the end of the piston rod of the primary lifting cylinder 10 and connected to a PLC controller via a signal line. It is also linked to the primary feeding baffle 3 via a PLC program to detect the stroke position of the primary lifting cylinder 10 in real time. When the primary lifting plate 9 rises to a set height, a signal is triggered to control the primary feeding baffle 3 to close, ensuring that only a single pipe enters the secondary bin, solving the problem of feeding multiple pipes. The primary feeding baffle 3 is connected to the servo motor via a gear and rack mechanism. The servo motor connects to the primary lifting plate 9, driving the baffle to open and close. Controlled by a PLC and synchronized with the position sensor 1 signal, the baffle closes after being triggered by the position sensor 1. This strips excess material from the primary lifting plate 9, increasing stripping efficiency by 40% and reducing the failure rate to 2%. The secondary material presence / absence switch 4 is installed 10cm above the secondary hopper inlet and connected to the PLC controller via cable, forming a closed-loop control link with the primary lifting cylinder 10. It detects whether there is material in the secondary hopper: if empty, it triggers the primary lifting cylinder 10 to replenish material; if full, it pauses replenishment, ensuring a secondary hopper empty response time of ≤0.5 seconds and reducing downtime by 80%. The secondary loading baffle, located at the secondary hopper inlet, is driven by a servo motor and a gear and rack mechanism to open and close, synchronized with the secondary lifting cylinder. 7. Synchronized operation controls the feeding rhythm of the secondary hopper, preventing multiple pipes from entering the lifting channel simultaneously. This ensures that the secondary lifting plate 6 only transports a single pipe at a time, guaranteeing stable material supply to the production line. During operation, the secondary lifting plate 6 is connected to the piston rod of the secondary lifting cylinder 7 via a linkage mechanism, driven by the cylinder to move up and down. Located below the outlet of the secondary hopper, it forms a vertical conveying path with the primary lifting plate 9 to receive pipes from the secondary hopper and smoothly lift them to the designated position on the production line. The secondary lifting cylinder 7 is connected to an air pump via pneumatic piping, with the piston rod end fixed to the bottom of the secondary lifting plate 6 and controlled by the secondary material presence / absence switch 4. By driving the secondary lifting plate 6 to rise and fall, it transports the pipes to the production line, increasing the feeding speed by 30% and adapting to high-performance applications. To meet the demands of the high-speed production line, the storage bin 8 is located at the bottom of the equipment and is divided into upper and lower layers. The inclined slide connects to the primary lifting plate 9. The upper layer is a buffer isolation area with an inclination of 15°, and the lower layer is the lifting area, used to store nylon corrugated pipes to be lifted. The layered design reduces the pressure of accumulation. The primary lifting plate 9 is fixed to the top of the piston rod of the primary lifting cylinder 10. It rises and falls with the cylinder and directly contacts the lower slide of the storage bin 8, lifting the pipe material in the storage bin 8 from the lower layer to the position of the primary feeding baffle 3. The primary lifting cylinder 10 is connected to an air pump through a pneumatic pipeline. The end of the piston rod is fixed to the bottom of the primary lifting plate 9. It is linked by the PLC controller and the secondary material presence / absence switch 4 to provide power to drive the primary lifting plate 9 to rise and fall, completing the primary feeding action.

[0021] The working principle of this utility model is as follows: As shown in the figure, the lower layer of the storage bin (8) is filled with nylon corrugated pipes, the first-level lifting plate (9) is located at the lowest point, the second-level bin is empty, the first-level lifting cylinder (10) is started, and the first-level lifting plate (9) is driven to rise to the preset height.

[0022] First-stage lifting and stripping, cylinder drive: The first-stage lifting cylinder (10) starts and drives the first-stage lifting plate (9) to rise to the preset height. Sensor trigger: The position sensor (1) detects that the cylinder is in place and sends a signal to the PLC. Baffle closure: The first-stage feeding baffle (3) closes at a speed of 0.2 seconds, stripping excess pipe material, and only one piece enters the second-stage silo.

[0023] Secondary detection and replenishment, silo detection: The secondary material switch (4) monitors the status of the secondary silo in real time. If empty: PLC triggers the primary lifting cylinder (10) to replenish material repeatedly until the pipe material is detected to be in place. If full: The secondary feeding baffle (5) opens and the secondary lifting cylinder (7) starts. Secondary conveying: The secondary lifting cylinder (7) drives the secondary lifting plate (6) to rise and send the pipe material to the production line.

[0024] The circulating material feeding system uses a PLC to form a closed-loop control, dynamically adjusting the rhythm of the first and second level actions to ensure continuous material feeding.
