Description

Technical Field

[0001] This utility model relates to the technical field of pipe feeding equipment, and specifically discloses an automatic feeding device for PVC drainage pipes. Background Technology

[0002] PVC drainage pipes are made from sanitary-grade polyvinyl chloride (PVC) resin as the main raw material, with the addition of appropriate amounts of stabilizers, lubricants, fillers, colorants, etc., and are produced through processes such as extrusion molding and injection molding. They are pipes used for drainage and have good physical properties, excellent chemical properties and good hydraulic properties. They are widely used in indoor drainage systems, rainwater drainage systems and drainage pipeline construction in municipal engineering and other fields in the building industry.

[0003] Chinese patent CN209193027U discloses a material feeding device for drainage pipe production, including a material feeding mechanism, a lifting mechanism, and a material collection frame; the material feeding mechanism includes a frame, a primary tilting material feeding mechanism, and a secondary tilting material feeding mechanism, and a controller is installed on the frame; an arc-shaped receiving platform is provided between the material feeding mechanism and the lifting mechanism, and a buffer mechanism is provided on the arc-shaped receiving platform; a drainage pipe position detection mechanism is also provided on the frame located at the end of the conveying of the primary tilting material feeding mechanism. This invention separates the material feeding mechanism into a primary tilting feeding mechanism and a secondary tilting feeding mechanism inclined at the bottom of the primary tilting feeding mechanism. This allows the drain pipe from the drain pipe extruder to fall from the primary tilting feeding mechanism onto the secondary tilting feeding mechanism, thus buffering the impact of the falling drain pipe and preventing damage caused by direct falling. However, the above device cannot adjust the distance between the two arc-shaped receiving platforms and the two lifting mechanism frames according to the length of the pipe, which affects the practicality of the device to some extent. Therefore, in order to solve the above problems, this invention proposes an automatic feeding device for PVC drain pipes. Utility Model Content

[0004] The present invention aims to provide an automatic feeding device for PVC drainage pipes, which can adjust the distance between the two arc-shaped receiving platforms and the two frames according to the length of the drainage pipe being fed, thereby improving the practicality of the device.

[0005] This utility model is achieved through the following technical solution: An automatic feeding device for PVC drainage pipes includes a tilting and discharging mechanism and a receiving mechanism. The receiving mechanism is located on one side of the tilting and discharging mechanism. The receiving mechanism includes two arc-shaped receiving platforms. A lifting mechanism is located on the side of each arc-shaped receiving platform away from the tilting and discharging mechanism. The lifting mechanism includes two symmetrically arranged frames. A drive sprocket is located on one side of each frame, and a driven sprocket is located above the drive sprocket. A chain meshes between the drive sprocket and the driven sprocket. A material collection frame is located on one side of the lifting mechanism. A slider is located below the arc-shaped receiving platforms. A bidirectional lead screw is threaded through the inside of the slider, and a sliding groove is slidably connected to the outside of the slider. A connecting shaft is located on one side of the drive sprocket. Multiple first connecting shafts arranged in a linear array are located at one end of the connecting shaft, and second connecting shafts are located at the ends of the first connecting shafts away from the connecting shaft.

[0006] As a further feature of the above solution, an arc-shaped rubber sheet is provided above the arc-shaped receiving platform, and a baffle is provided at one end of the arc-shaped receiving platform. The baffle is close to one side of the frame, which facilitates the alignment of the frame, chain, lifting plate and other components with the arc-shaped receiving platform.

[0007] As a further feature of the above solution, the bidirectional lead screw is threadedly connected to the slider, and both ends of the slide groove are connected to end plates.

A first retractable dust cover and a second retractable dust cover are respectively provided on both sides of the slider. The two ends of the first retractable dust cover are respectively connected to the two sliders, and the two ends of the second retractable dust cover are respectively connected to the slider and the end plate. This can protect the bidirectional lead screw and prevent dust and other impurities from adhering to the surface of the bidirectional lead screw.

[0008] As a further feature of the above scheme, two lifting plates are provided on one side of the chain. The side of the drive sprocket away from the connecting shaft passes through the interior of the frame and is rotatably connected to the frame.

Bolts are provided through the protrusions and the interior of the connecting grooves, and nuts are threaded onto the outer side of the bolts. This facilitates connecting the connecting shaft, the first connecting shaft, and the second connecting shaft together to form a complete transmission shaft, which helps to adjust the distance between the two frames by adjusting the number of the first connecting shafts.

[0010] As a further feature of the above solution, the bottom of the collection frame is provided with a base plate, and multiple insertion holes arranged in a linear array are provided on both sides of the base plate. Multiple baffles arranged in a linear array are provided on the upper sides of both sides of the base plate. An insertion rod is provided below the baffle, and the insertion rod passes through the interior of the insertion hole and is inserted into the insertion hole, so as to facilitate the removal and installation of the baffle and the removal of the drain pipe. Rollers are symmetrically provided at both ends of the lower part of the base plate. All rollers are universal wheels, and at least one of them is a universal brake wheel, which facilitates the adjustment and fixing of the position of the collection frame.

[0011] The flipping and feeding mechanism and the drain pipe extruder (not shown) at one end of the present invention are known prior art. For details on the specific structure and usage of the flipping and feeding mechanism and the lifting mechanism, please refer to the first flipping and feeding mechanism and lifting mechanism in Chinese Patent No. CN209193027U.

[0012] The present invention has the following beneficial effects during use: The combination of sliders, bidirectional lead screws, and slides in the receiving mechanism allows users to adjust the distance between the two sliders and the arc-shaped receiving platform simultaneously by rotating the bidirectional lead screw. This enables the arc-shaped receiving platform and the arc-shaped rubber sheet above it to support drain pipes of different lengths. The combination of two retractable dust covers keeps the bidirectional lead screw clean and reduces the amount of work required for cleaning it.

[0013] The combination of the connecting shaft, the second connecting shaft, and multiple first connecting shafts in the lifting mechanism allows for adjustment of the distance between the two connecting shafts and components such as the frame by adjusting the number of first connecting shafts between the connecting shaft and the second connecting shaft. This enables the two chains and the lifting plate on one side to be suitable for lifting drainage pipes of different lengths. Attached Figure Description
