Description

Technical Field

[0001] The present invention belongs to the technical field of central feeding and conveying systems, and particularly relates to a multi-functional central feeding and conveying system. Background Art

[0002] The central feeding system is designed for the production of plastic products in an injection molding workshop, realizing uninterrupted unmanned continuous molding operations. It can change the raw material variety and the combined use mode of multi-color materials according to needs, and realize the automation of the coloring process.

[0003] Since the central feeding system uses pipeline transportation, when the pipeline is unfortunately blocked, it is necessary to temporarily shut down and replace the pipeline, resulting in the problem that the conventional central feeding system lacks the function of switching pipelines during the working process.

[0004] For this reason, we propose a multi-functional central feeding and conveying system to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem that the conventional central feeding system lacks the function of switching pipelines during the working process, and a multi-functional central feeding and conveying system is proposed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A multi-functional central feeding and conveying system includes a valve housing. A valve core is slidably and sealingly installed inside the valve housing. A threaded rod is fixedly connected to the side end of the valve core. A threaded knob is threadedly installed outside the threaded rod. The threaded knob is rotatably installed at the side end of the valve housing, and the threaded rod slidably penetrates through the valve housing. The valve housing is used to connect the pipelines of the central feeding and conveying system. When the pipeline connected to the valve housing is blocked, a new pipeline is installed at another interface of the valve housing, and then the threaded knob is rotated to drive the threaded rod to move. The threaded rod drives the valve core to move, so that the valve core switches to connect to another interface and blocks the previous channel at the same time. Then the blocked pipeline is removed, realizing the solution of the pipeline blockage problem during the working process, enabling the central feeding and conveying system to have the function of dealing with pipeline blockage during the working process, and improving the practicability.

[0008] Preferably, the valve housing includes a housing, a first branch pipe, a second branch pipe, a guide sleeve, and a restraint hook. The first branch pipe and the second branch pipe are fixedly connected to the side of the housing. The guide sleeve is fixedly connected to one end of the housing. The restraint hook is fixedly connected to the outer end of the guide sleeve. The guide sleeve is used to guide the sliding of the threaded rod. The restraint hook is used to rotatably connect the threaded knob to the guide sleeve. The valve core slides inside the housing to switch the channel, facilitating the valve core to slide inside the housing to switch the channel.

[0009] Preferably, the valve housing further includes a limit ring fixedly connected to one end of the housing opposite to the guide sleeve. The limit ring blocks the side of the valve core to prevent the valve core from being misaligned and ensure that the valve core is aligned with the first branch pipe.

[0010] Preferably, the threaded knob includes a nut and an operation disc. The nut is rotatably installed in the restraint hook, the nut is in movable contact with the guide sleeve, and the inner end of the operation disc is fixedly connected to the outside of the nut. The operation disc is used to increase the length of the operation lever. Manually rotate the operation disc, and use the valve housing to increase the force acting on the nut, facilitating the manual operation of the threaded knob.

[0011] Preferably, the threaded rod includes a threaded rod body threadedly installed in the nut, and a rotation limiting groove is provided at the upper end of the threaded rod body. The rotation limiting groove is used to limit the rotation of the threaded rod body. Acting on the valve core through the threaded rod body can prevent the valve core from rotating and improve the stability of the valve core angle.

[0012] Preferably, the threaded rod further includes a stop block fixedly connected to the outer end of the rotation limiting groove. The stop block blocks the outside of the threaded rod body to prevent the threaded rod body from stabbing the hand and improve the safety factor of use.

[0013] Preferably, the valve core includes a tubular retaining shell, a connecting plate, and a movable plug. The tubular retaining shell, the connecting plate, and the movable plug are slidably and sealingly installed in the housing. One end of the movable plug opposite to the connecting plate is fixedly connected to the threaded rod body, and a guiding groove is provided between the movable plug and the connecting plate. Particles in the airflow are guided to the first branch pipe or the second branch pipe through the guiding groove, reducing the turning resistance of the airflow and particles and lowering the possibility of blockage. When the guiding groove is aligned with the second branch pipe, the tubular retaining shell is used to block the first branch pipe to achieve channel switching, facilitating channel switching and maintaining the smoothness of the flow channel.

[0014] In summary, the technical effects and advantages of the present invention are as follows:

[0015] 1. The valve housing is used to connect the pipes of the central feeding and conveying system. When the pipe connected to the valve housing is blocked, a new pipe is installed on another interface of the valve housing, and then the threaded knob is rotated to drive the threaded rod to move. The threaded rod drives the valve core to move, so that the valve core switches to connect to another interface and blocks the previous channel at the same time. Then the blocked pipe is removed, realizing the solution to the pipe blockage problem during the working process, enabling the central feeding and conveying system to have the function of dealing with pipe blockage during the working process, and improving the practicability.

[0016] 2. The guide sleeve is used to guide the sliding of the threaded rod, and the restraint hook is used to rotatably connect the threaded knob to the guide sleeve. The valve core slides in the housing to switch channels, facilitating the valve core to slide in the housing to switch channels.

[0017] 3. The limit ring blocks the side of the valve core to prevent the valve core from being misaligned and ensure that the valve core is aligned with the first branch pipe.

[0018] 4. Increase the length of the operating lever using the operating panel, manually rotate the operating panel, and use the valve housing to increase the force acting on the nut to facilitate manual operation of the threaded knob.

[0019] 5. Limit the rotation of the threaded rod body using the rotation limit groove, and act on the valve core through the threaded rod body to prevent the valve core from rotating and improve the stability of the valve core angle.

[0020] 6. Use the stopper to block the outside of the threaded rod body to prevent the threaded rod body from stabbing the hand and improve the safety factor during use.

[0021] 7. Particles in the air flow are guided to the first branch pipe or the second branch pipe through the guiding groove, reducing the turning resistance of the air flow and particles and reducing the possibility of blockage. When the guiding groove is aligned with the second branch pipe, use the tubular retaining shell to block the first branch pipe to achieve channel switching, facilitating channel switching and maintaining the smoothness of the flow channel.
