Description
TECHNICAL FIELD
[0001] The utility model relates to injection molding machine technical field, concretely relates to a vertical pipe winding mechanism anti -over -rotation protection device. BACKGROUND
[0002] The traditional injection molding machine is a kind of equipment for producing various plastic products. Vertical rotating disc is an important part in injection molding machine, is used to rotate mould, and is used to inject molten plastics in injection molding machine into different gates of mould, to manufacture the plastic products of required multiple color combinations.
[0003] However, the traditional injection molding machine lacks vertical rotating disc anti -over -rotation device, and over -rotation phenomenon still occurs due to inertia when vertical rotating disc reaches stop position, and vertical rotating disc over -rotation will lead to inaccurate stop position, even damage rotating shaft and mechanical stop block of rotating disc surface, which affects the production efficiency and safety of the traditional injection molding machine. SUMMARY
[0004] The utility model solves the technical problem that the injection molding machine lacks vertical rotating disc anti -over -rotation device, and over -rotation phenomenon is prone to occur, to damage rotating shaft and mechanical stop block of rotating disc surface.
[0005] In order to solve the above technical problem, the technical scheme of the utility model is to provide a vertical pipe winding mechanism anti -over -rotation protection device, including vertical pipe winding body and anti -over -rotation switch, the vertical pipe winding body upper end is equipped with arc convex, and the anti -over -rotation switch is located at the periphery of vertical pipe winding body and is close to arc convex.
[0006] Optionally, the anti -over -rotation switch includes first proximity switch and second proximity switch, the first proximity switch and the second proximity switch are all aligned with arc convex, and a horizontal spacing is arranged between the first proximity switch and the second proximity switch.

[0013] The following Figures 1-2 The utility model makes further detailed description.
[0014] The utility model discloses a vertical winding pipe mechanism prevents over -rotation protection device, refer to Figure 1 And Figure 2 , including vertical winding pipe body 1 and prevent over -rotation switch, vertical winding pipe body 1 upper end is equipped with circular arc convex 5, prevent over -rotation switch and are close to circular arc convex 5 at vertical winding pipe body 1 periphery, prevent over -rotation switch including first proximity switch 2 and second proximity switch 3, first proximity switch 2 and second proximity switch 3 are all aligned circular arc convex 5, and horizontal spacing is equipped between two.
[0015] In further implementation, first proximity switch 2 and second proximity switch 3 are connected in vertical winding pipe body 1 periphery through fixed mounting sheet metal 4, because super soft line can only twist 270 DEG at most, therefore the central angle of circular arc convex 5 is equipped as 270 DEG.
[0016] Specifically, first proximity switch 2 and second proximity switch 3 adopt normally open contact, and circular arc convex 5 is equivalent to inductive switch, when vertical winding pipe body 1 normally rotates, first proximity switch 2 and second proximity switch 3 induct to circular arc convex 5, always be in trigger state, lose induction after turning over 270 DEG, and separate trigger state.
[0017] EMBODIMENT
[0018] In this embodiment, refer to Figure 1 , vertical winding pipe body 1 rotates clockwise, and second proximity switch 3 is located in front of first proximity switch 2, that is, when vertical winding pipe body 1 rotates, second proximity switch 3 inducts or disconnects induction with circular arc convex 5 earlier than first proximity switch 2, and second proximity switch 3 and first proximity switch 2 are connected with the PLC controller of injection molding machine;
[0019] When second proximity switch 3 and first proximity switch 2 are all in normal trigger state, vertical winding pipe body 1 normally rotates, when circular arc convex 5 leaves second proximity switch 3, the PLC controller receives the disconnect signal of second proximity switch 3, and vertical winding pipe body 1 stops rotating, and completes a job, if over -rotation phenomenon occurs, vertical winding pipe body 1 continues to rotate, makes first proximity switch 2 disconnect, and the PLC controller receives the disconnect signal, so that the machine stops completely, to prevent damaging the mold and the turntable.
[0020] In other embodiments, if vertical winding pipe body 1 rotates counterclockwise, the positions of second proximity switch 3 and first proximity switch 2 can be exchanged.
[0021] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
