Description

Technical Field

[0001] The present application relates to the field of PVC pipe processing equipment, and particularly to a propulsion and positioning device for PVC pipe production. Background Art

[0002] PVC pipes are usually extruded from raw materials by an extruder to form a tube shape and directly enter a vacuum shaping machine for shaping and cooling. The movement of the PVC pipe from the vacuum shaping machine and subsequent movement is only propelled by the extrusion thrust of the extruder. When the PVC pipe is extruded from the extruder, its temperature is relatively high and the pipe is relatively soft. When the length of the pipe is large, resulting in a large weight and thrust, it is prone to extrusion deformation.

[0003] In the existing related technologies, for example, the patent document with the publication number CN215320033U discloses a propulsion and positioning device for PVC hose production. Through the coordinated use of a motor, a first rotating rod, a second rotating rod, pulleys, a belt, a rotating roller, and a conveyor belt, this solution can automatically propel the PVC hose.

[0004] Although the above-mentioned existing technology can propel the movement of the pipe body, its structure is complex, and the production cost and maintenance cost are relatively high, which does not meet the production efficiency of enterprises. Utility Model Content

[0005] In order to overcome the deficiencies of the above-mentioned existing technology, the present application provides a propulsion and positioning device for PVC pipe production.

[0006] The propulsion and positioning device for PVC pipe production provided by the present application adopts the following technical solutions:

[0007] A propulsion and positioning device for PVC pipe production includes a frame body, a rotating roller arranged on the frame body, and a driving device arranged on the frame body for driving the rotating roller to rotate; at least two rotating rollers are arranged in parallel up and down, an airbag is arranged on the rotating roller, and the airbag is connected to a pneumatic controller.

[0008] Further, the diameter of the middle of the rotating roller is smaller than the diameters of both ends.

[0009] Further, a rubber layer is arranged on the outer surface of the airbag.

[0010] Further, a photoelectric switch for controlling the operation or stop of the pneumatic controller is arranged on the frame body, and the photoelectric switch is electrically connected to the pneumatic controller.

[0011] The present application has the following beneficial technical effects:

[0012] By setting a rotating roller with an airbag on the frame, when the airbag is inflated, it can be squeezed against the outer wall of the PVC pipe. By driving the rotating roller to rotate through the driving device, the PVC pipe can be driven to move. Due to the compressibility of the airbag, it can adapt to PVC pipes of different calibers and is in soft contact with the PVC pipe, effectively protecting the PVC pipe from being scratched.

[0016] The technical solutions in the present application will be further described in detail below with reference to the accompanying drawings.

[0017] An embodiment of the present application discloses a propulsion and positioning device for PVC pipe production. Please refer to Figure 1 and Figure 2 , a propulsion and positioning device for PVC pipe production includes a frame 1, a rotating roller 2 provided on the frame 1, and a driving device 3 provided on the frame 1 for driving the rotating roller 2 to rotate; at least two rotating rollers 2 are provided and arranged parallel to each other up and down, an airbag 4 is provided on the rotating roller 2, and the airbag 4 is connected to an air pressure controller 5.

[0018] Among them, the driving device 3 includes a motor 31 and gears 32 meshing with each other on two rotating rollers 2. The motor 31 is fixedly provided on the frame 1, and the output shaft of the motor 31 is coaxially fixed to one of the rotating rollers 2. When the motor 31 starts, it drives the rotating roller 2 to rotate, and drives the other rotating roller 2 to rotate synchronously and reversely through the meshing of the two gears 32 for propelling the PVC pipe to move.

[0019] The air pressure controller 5 is used to automatically control the air pressure in the airbag 4. If the pressure of the airbag 4 is less than the set pressure, the air pressure controller 5 pressurizes the inside of the airbag 4, and vice versa releases the pressure in the airbag 4 to achieve automatic pressure control.

[0020] Further, a photoelectric switch 6 for controlling the operation or stop of the air pressure controller 5 is provided on the frame body 1, and the photoelectric switch 6 is electrically connected to the air pressure controller 5. When there is no PVC pipe on the rotating roller 2, the air pressure controller 5 does not act, and the airbag 4 is at normal pressure; when the photoelectric switch 6 detects that the PVC pipe passes through the rotating roller 2, it controls the air pressure controller 5 to act, and the airbag 4 is inflated to abut against the outer wall of the PVC pipe, and the PVC pipe is driven to move by the rotation of the rotating roller 2 and the airbag 4.

[0021] The middle diameter of the rotating roller 2 is smaller than the diameters at both ends, that is, the outer peripheral surface of the rotating roller 2 is arc-shaped to adapt to the circular structure of the PVC pipe, so that the airbag 4 can fit the PVC pipe more fully.

[0022] A rubber layer is provided on the outer surface of the airbag 4 to increase the friction between the airbag 4 and the outer surface of the PVC pipe, and at the same time play a protective role for the airbag 4.

[0023] The implementation principle of the embodiment of the present application is as follows: when there is no PVC pipe on the rotating roller 2, the airbag 4 is at normal pressure, and the space between the two rotating rollers 2 is larger to facilitate the PVC pipe to pass through the gap between the two rotating rollers 2; when the photoelectric switch 6 detects the PVC pipe, it controls the air pressure controller 5 to act, inflates the airbag 4 to make the airbag 4 bulge and abut against the outer wall of the PVC pipe, and at the same time the motor 31 rotates to drive the rotating roller 2 and the airbag 4 to rotate to push the PVC pipe to move. When the photoelectric switch 6 detects that the PVC pipe has detached from the rotating roller 2, it controls the air pressure controller 5 to act to release the pressure in the airbag 4 for the next push of the PVC pipe.

[0024] It should be noted that all directional indications (such as up, down, left, right, front, and back) in the embodiments of the present invention are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0025] In the present invention, unless otherwise clearly specified and limited, terms such as "connection" and "setting" should be understood in a broad sense. For example, "setting" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
