Technical Field

[0001] The invention relates to the technical field of municipal construction equipment, and in particular to the design of processing and manufacturing equipment for inspection wells. Background Art

[0002] At present, with the continuous improvement of my country's urbanization level, the management of corresponding drainage systems and facilities has received more and more attention. In the drainage system, drainage pipes and inspection wells are common components. Among them, inspection wells are mostly used in building communities, such as residential areas, public building areas, factory areas, etc., and are generally located at the intersection of drainage pipes, turning points, places where pipe diameters or slopes change, waterfalls, etc., in order to facilitate regular inspection, cleaning and dredging or down-well operation inspection.

[0003] For example, a Chinese patent document with publication number CN201920248328.3 discloses an inspection well, which is mostly made of materials such as polyethylene, and needs to be welded when connected to the pipeline. The inspection well includes a main body and a bottom cover connected thereto. In the prior art, there are many defects in the production process of the bottom cover. On the one hand, the manual labor intensity is high, and the position of the polyethylene material is not precise after it is spread out, and the overall formability of the bottom cover is not strong. On the other hand, the polyethylene material is formed into a bottom cover, and the process of welding the bottom cover to the inspection well body is not smooth enough, and the error rate is high. Summary of the invention

[0004] The purpose of the present invention is to provide a bottom cover manufacturing device suitable for an inspection well, which has a high degree of automation, low labor intensity for workers, and controllable material positioning during the bottom cover molding process, and good molding effect.

[0005] The above technical purpose of the present invention is achieved through the following technical scheme: a bottom cover manufacturing device suitable for inspection wells, comprising a discharging device, the discharging device comprising an extrusion device for extruding materials, the extrusion device comprising an extrusion port, and also comprising a turntable located below the extrusion port for carrying materials, a turntable driving device for driving the turntable to rotate, a slide rail, a moving table connected to the turntable, and a moving table driving device for driving the moving table to move on the slide rail.

[0006] As a preferred embodiment of the present invention, it also includes a shaping device for shaping the flatness of the material on the turntable.

[0007] As a preferred embodiment of the present invention, the shaping device comprises a connecting frame, a connecting shaft connected to the connecting frame, and a pressing head installed on the connecting shaft.

[0008] As a preferred embodiment of the present invention, the pressure head includes a plurality of flat pressing single wheels, and the plurality of flat pressing single wheels are commonly connected to the connecting shaft, and the connecting shaft is located on the axis of the flat pressing single wheels.

[0009] As a preferred embodiment of the present invention, the connection frame is provided with an escape space for the material extruded by the extrusion device to pass through.

[0010] As a preferred embodiment of the present invention, the shaping device further comprises a rotating shaft, and the bottom cover manufacturing equipment further comprises a pressing driving device for driving the connecting frame and the pressing head to rotate and press downward with the rotating shaft as the axis.

[0011] As a preferred embodiment of the present invention, the extrusion port is a long flat slot.

[0012] As a preferred embodiment of the present invention, it also includes a cutting knife for cutting the material at the extrusion port.

[0013] As a preferred embodiment of the present invention, a heating device for heating the turntable is also included.

[0014] As a preferred embodiment of the present invention, the moving platform includes a support frame and a pulley installed on the support frame.

[0015] In summary, the present invention has the following beneficial effects:

[0016] 1. By arranging a rotating turntable and a slidable moving table under the extruder, not only the position of material forming can be accurately controlled, but also the same equipment can be used to produce bottom covers of different sizes.

[0017] 2. The flat design of the extrusion port makes the bottom cover molding effect better.

[0018] 3. The shaping device performs flat pressing operation on the material, so that the bottom cover forming height can be controlled.

[0019] 4. The pressure head adopts a multi-wheel driven design, which not only makes the material flattened more evenly, but also makes the bottom cover have a corrugated appearance after forming.

[0020] 5. After the cutting knife cuts the material, more of the material will be continuously beaten by the pressure head, so that this part of the material remains compact and uniform.

[0021] 6. A heating device is installed on the turntable to keep the bottom cover at a suitable temperature during the production process, and also facilitate the later connection with the main part of the inspection well. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0027] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

[0028] Embodiment 1, as Figure 1 As shown, a bottom cover manufacturing device suitable for inspection wells includes a discharging device 4, which includes a material box 41 and an extrusion device 42. The material used to make the bottom cover, such as polyethylene, is placed in the material box 41 and extruded through the extrusion device 42. As for the material box 41 and the extrusion device 42, these parts are the existing technical content, and this solution does not make any changes to these two parts, which will not be repeated here.

[0029] like Figure 2 As shown, the extrusion device 42 includes an extrusion port 421. In this embodiment, the extrusion port 421 is a long strip opening, and the material is in a flat strip shape when extruded. A shaping device 5 is installed below the extrusion device 42. The main part of the shaping device 5 is a connecting frame 52, which is a frame-type design structure. The connecting frame 52 has an escape space 521 for the part of the material extrusion position. The escape space 521 avoids contact with the high-temperature material coming out of the extrusion port 421, so that the material can fall smoothly onto the turntable 3.

[0030] like Figure 1 As shown, the turntable 3 is included, and the turntable 3 rotates under the drive of a turntable driving device (such as a motor in the prior art), while the extrusion port 421 is stationary relative to the ground, and the material falls on the continuously rotating turntable 3.

[0031] In actual production, the bottom cover is a disc-shaped one, and the diameter of the disc is different according to different product specifications. In this embodiment, the same extrusion port 421 can be used to produce bottom covers of different specifications. Therefore, it is not necessary to change the model of the extrusion port 421 in response to different production requirements, thereby increasing production efficiency and reducing equipment maintenance costs.

[0032] Specifically, a slide rail 2 is laid on the ground, and a turntable 3 is connected to a moving platform 1. The moving platform 1 includes a support frame 11 and a pulley 12. The moving platform 1 slides on the slide rail 2 under the drive of a moving platform driving device (such as a servo motor in the prior art). Through the automatic numerical control in the prior art, the moving speed, moving distance, and moving trajectory of the moving platform 1 can be accurately controlled. This makes the position of the turntable 3 falling from the extrusion port 421 adjustable, and the bottom cover with different diameters can be manufactured by moving the moving platform 1.

[0033] When the material first falls into the turntable 3, it often has a certain height and is not flat. In this embodiment, the shaping device 5 is used to flatten the material. Figure 2 As shown, a pressure head 53 is provided at the front end of the connection frame 52. The user pre-adjusts the height of the pressure head 53 from the turntable 3. Under the rotation of the turntable 3, the pressure head 53 flattens and spreads the material on the turntable 3. Furthermore, the pressure head 53 includes a plurality of flattening single wheels 531 connected to the connecting shaft 54. Each adjacent flattening single wheel 531 can rotate relative to the connecting shaft 54, and there is a small gap between adjacent flattening single wheels 531. This design makes the flattening effect more uniform and smooth on the one hand, and makes the final bottom cover have corrugations on the other hand.

[0034] In this embodiment, the production process of the bottom cover is from the outside to the inside, that is, through the movement of the moving table 1, the horizontal distance between the extrusion port 421 and the center of the circle of the turntable 3 is gradually reduced. When the production is about to be completed, the material at the extrusion port 421 is cut by a cutting knife, and the material discharge is stopped. At this time, this large piece of material falls into the center of the bottom cover. At this time, the shaping device 5 presses down and hits this part of the material.

[0035] Specifically, Figure 2 As shown, the connecting frame 52 is connected to the rotating shaft 51. Under the drive of the downward pressing driving device (such as a cylinder, not shown in the figure), the connecting frame 52 rotates up and down with the rotating shaft 51 as the axis, and the pressing head 53 performs a beating action on this part of the larger material. Since this part of the material is a little more than the material in the ordinary falling stage, the beating action can make this part of the material flat and uniform at the center position, and finally achieve the molding effect of the bottom cover.

[0036] Figure 1 The bottom cover 9 is the final molded product.

[0037] The heating device is also included. The specific form of the heating device is not limited, and can adopt open flame heating or electric heating in the prior art. The heating device is used to heat the turntable 3, so that the bottom cover 9 has a suitable processing temperature during the manufacturing process, which is convenient for the subsequent connection of the bottom cover 9 with the inspection well body.
