Description

Technical Field

[0001] This utility model relates to the field of production and packaging technology of large-diameter PE pipes, and in particular to a sensing and triggering device for large-diameter pipes used in dusty environments. Background Technology

[0002] Large-diameter PE pipes undergo a series of automated packaging processes during production. After being extruded by a front-end extruder and cut by a cutting machine, they require subsequent labeling, measurement, and sealing. Each of these automated packaging processes necessitates a corresponding pipe sensing triggering device. Because the production environment for large-diameter pipes is open, dust accumulation is common, and the pipe cutting process itself generates plastic shavings. Commonly used photoelectric induction switches and capacitive proximity switches can be falsely triggered by dust adhering to the sensing surface. This can cause the large-diameter pipes to collide with and damage the automated packaging equipment, leading to production line shutdowns and further economic losses. Therefore, a dust-resistant sensing triggering device is needed to detect large-diameter pipes and activate the corresponding trigger signal. Utility Model Content

[0003] To address the aforementioned problems, this utility model aims to provide a large-diameter pipe induction triggering device applicable to dusty environments, thereby solving the problem of dust affecting the large-diameter pipe induction triggering device.

[0004] The technical problem solved by this utility model can be achieved by the following technical solution: a large-diameter pipe induction triggering device for use in dusty environments, including a guide movable plate, a general fixed frame, a ball bearing limit switch and a reset mechanism. The guide movable plate is arranged above the general fixed frame, and a reset mechanism is arranged between the guide movable plate and the general fixed frame. The ball bearing limit switch is fixed on the general fixed frame and is located below the guide movable plate.

[0005] The reset mechanism includes a movable guide shaft, a reset spring, a linear bearing, and a fixed ring. The linear bearing is mounted on the overall fixed frame. The movable guide shaft is located below the movable guide plate and passes through the linear bearing. A fixed ring is located at the lower end of the movable guide shaft and is positioned below the linear bearing. A reset spring is fitted around the outer side of the movable guide shaft. The upper end of the reset spring is connected to the lower part of the movable guide plate, and the lower end of the reset spring is connected to the linear bearing.

[0006] A buffer mechanism is provided between the overall fixed frame and the guide movable plate. The buffer mechanism includes a buffer pad mounting column and a limiting buffer pad. The lower end of the buffer pad mounting column is fixed to the overall fixed frame, and the limiting buffer pad is fixed to the upper end of the buffer pad mounting column.

[0007] The overall fixing frame is equipped with two buffer mechanisms, which are located on both sides of the ball bearing limit switch.

[0008] The guide plate is fixed on the guide plate mounting base, and the lower part of the guide plate mounting base is fixedly connected to the upper end of the movable guide shaft.

[0009] One side of the guide plate is inclined downwards, and the inclined part comes into contact with the large-diameter pipe.

[0010] The guide plate is made of polytetrafluoroethylene.

[0011] Compared with existing technologies, this invention has the following advantages: It is applied to the induction triggering of large-diameter pipelines in dusty environments, enabling sensing and triggering of the pipeline's arrival without being affected by dust. The guide plate is made of polytetrafluoroethylene (PTFE), a soft material that will not damage the pipeline surface. It also possesses good self-lubricating properties, ensuring smooth guidance of the large-diameter pipeline and improving the reliability of the induction triggering. The limit buffer effectively prevents excessive downward movement of the guide plate mounting base from damaging the ball bearing limit switch when external force is too great. It also provides good cushioning, improving the overall device's shock resistance and further enhancing the reliability of the induction triggering. The reset mechanism quickly lifts the guide plate back to its original position after the large-diameter pipeline leaves the device, thus resetting the ball bearing limit switch signal for the next induction triggering.

Detailed Implementation

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0017] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] Combined with appendix Figures 1 to 3 As shown, this embodiment discloses a large-diameter pipe induction triggering device for use in dusty environments, including a guide plate 1, a main frame 9, a ball bearing limit switch 2, a reset mechanism, and a buffer mechanism. The guide plate 1 is positioned above the main frame 9, and four reset mechanisms are arranged between the guide plate 1 and the main frame 9. The ball bearing limit switch 2 is fixed to the main frame 9 by two hexagonal screws, and is located below the guide plate 1. A buffer mechanism is provided between the main frame 9 and the guide plate 1.

[0019] Four reset mechanisms are respectively located at the four corners of the overall fixed frame 9. Each reset mechanism includes a movable guide shaft 8, a reset spring 5, a linear bearing 6, and a fixing ring 7. The linear bearing 6 is mounted on the overall fixed frame 9. The movable guide shaft 8 is located below the movable guide plate 1 and passes through the linear bearing 6. A fixing ring 7 is located at the lower end of the movable guide shaft 8, positioned below the linear bearing 6. The reset spring 5 is sleeved on the outer side of the movable guide shaft 8. The upper end of the reset spring 5 is connected to the lower part of the movable guide plate 1, and the lower end of the reset spring 5 is connected to the linear bearing 6. The reset spring 5 can quickly lift the movable guide plate 1 back to its original position after the large-diameter pipe 11 leaves the device, thereby resetting the signal of the ball bearing limit switch 2 for the next induction trigger.

[0020] Two buffer mechanisms are provided on the overall fixing frame 9, located on both sides of the ball bearing limit switch 2. Each buffer mechanism includes a buffer pad mounting post 4 and a limit buffer pad 3. The lower end of the buffer pad mounting post 4 is fixed to the overall fixing frame 9, and the limit buffer pad 3 is fixed to the upper end of the buffer pad mounting post 4. The limit buffer pad 3 is made of polyurethane. The limit buffer pad 3 effectively prevents the guide plate mounting base 10 from falling too far and damaging the ball bearing limit switch 2 when excessive external force is applied. It also provides good buffering to improve the overall device's shock resistance and further enhance the reliability of the inductive triggering. The buffer pad mounting post 4 is threadedly connected to the overall fixing frame 9, and the limit buffer pad 3 is fixedly connected to the buffer pad mounting post 4 with a single hexagonal screw.

[0021] The guide plate 1 is fixed on the guide plate mounting base 10, and the guide plate 1 and the guide plate mounting base 10 are connected and fixed by six hexagon socket screws. The lower part of the guide plate mounting base 10 is fixedly connected to the upper end of the movable guide shaft 8, and the lower part of the guide plate mounting base 10 is connected to the upper end of the return spring 5.

[0022] One side of the guide plate 1 is tilted downwards to facilitate contact with the large-diameter pipe 11, causing the guide plate 1 to trigger the ball bearing limit switch 2 downwards, and the tilted part contacts the large-diameter pipe 11.

[0023] The guide plate 1 is made of polytetrafluoroethylene (PTFE). PTFE is relatively soft and will not damage the pipe surface. It also has good self-lubricating properties, which can ensure smooth guidance of the large-diameter pipe 11, improve the reliability of induction triggering, and will not damage the pipe surface.

[0024] This invention is applied to the sensing and triggering of large-diameter pipes in dusty environments, enabling the sensing and triggering of the arrival of large-diameter pipes without being affected by dust.

[0025] The specific implementation process of this utility model device in the production process is as follows: After the large-diameter pipe extrusion production line and the downstream automatic packaging equipment are started, the device is activated. The large-diameter pipe 11 is extruded from the extruder and cut by the cutting machine, continuously conveyed to the left. When the large-diameter pipe 11 enters the device from right to left, it is guided by the guide movable plate 1 and continues to move to the left. Under the influence of the gravity of the large-diameter pipe 11, the guide movable plate mounting base 18 and the polytetrafluoroethylene guide movable plate 1 on it move downward under the guidance of the four movable guide shafts 8 and the four linear bearings 6 until they are limited by the polyurethane limiting buffer pads 3 on the front and rear sides. At this time, the ball rocker arm on the ball rocker arm limit switch 2 is simultaneously pressed to the lower left by the guide movable plate mounting base 10, thereby triggering the ball rocker arm limit switch 2 to conduct, thereby connecting the arrival signal of the large-diameter pipe 11, so that the downstream packaging equipment receives the signal and grabs the large-diameter pipe 11 to start the downstream packaging process such as labeling, measuring, and wrapping of the large-diameter pipe 11. When the large-diameter pipe 11 is grasped and detached from the guide plate 1, the guide plate mounting base 10 and the guide plate 1 fixed thereon move upwards to their original positions under the action of the return spring 5. Simultaneously, the ball rocker limit switch 2 rotates to the upper right to return to its original position, and the ball rocker limit switch 2 closes. Afterwards, the device waits for the arrival of the next large-diameter pipe and triggers the sensor again, and the device operation is complete.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the utility model in any way. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
