Description

Technical Field

[0001] The utility model belongs to the technical field of material conveying, and in particular relates to a material switching device. Background Art

[0002] In the injection molding industry, centralized feeding systems are often used to transport multiple materials. Conventional centralized feeding systems are generally distribution trays for switching multiple materials. There are two common types of distribution trays: manual distribution trays, which require manual operation to plug and unplug the material pipe to complete the switching of the material pipe. The operation is cumbersome and it is easy to plug the wrong pipe, resulting in material waste; automatic distribution trays, which use servo motors and other drive devices to achieve automatic switching of material lines, but are large in size, expensive, and have long common pipe sizes, which poses the risk of not being cleaned properly. Therefore, a new material switching device is needed. Utility Model Content

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments.

[0027] like Figures 1 to 9 The figure shows a specific embodiment of the material switching device of the present utility model. The device includes 6 feeding units 2, an upper cleaning unit 1, a common unit 3, and a lower cleaning unit 5. Each feeding unit 2 is provided with a corresponding discharging unit 4, that is, 6 discharging units 4 are provided. Different feeding units 2 can correspond to the feeding ports of different types of materials, and different discharging units 4 can correspond to the discharging ports of different types of materials, or correspond to different molding machines.

[0028] The feeding unit 2, the upper cleaning unit 1, the discharging unit 4 and the lower cleaning unit 5 are all provided with driving components, and the feeding unit 2, the discharging unit 4, the upper cleaning unit 1 and the lower cleaning unit 5 all have a standby position. In the standby position, the feeding unit, the discharging unit, the upper cleaning unit and the lower cleaning unit are not docked with the common unit. Figure 1 As shown, each feeding unit, each discharging unit, the upper cleaning unit, and the lower cleaning unit are all in the standby position; each feeding unit 2 and the upper cleaning unit 1 share an upper common switching position, and when the feeding unit 2 or the upper cleaning unit 1 is located at the upper common switching position, the feeding unit 2 or the upper cleaning unit 1 is in a docking state with the common unit 3; each discharging unit 4 and the lower cleaning unit 5 share a lower common switching position, and when the discharging unit 4 or the lower cleaning unit 5 is located at the lower common switching position, the discharging unit 4 or the lower cleaning unit 5 is in a docking state with the common unit 3, as shown in FIG. Figure 3 As shown, one of the feed units 2 is located at the upper common switching position, and its corresponding discharge unit 4 is located at the lower common switching position. When the feed unit 2 and the corresponding discharge unit 4 are in the corresponding common switching positions and docked with the common unit, the specific material path is connected, and after the centralized conveying fan is started, the specific material can be conveyed to the required position, thereby realizing the switching to the conveying of the specific material; Figure 4 As shown, the upper cleaning unit 1 is located at the upper common switching position, and the lower cleaning unit 5 is located at the lower common switching position, thereby switching to a cleaning state. Specifically, after the delivery of one material is completed, if it is necessary to switch to a different material, the common unit can be cleaned and switched to a cleaning state. The driving component is used to drive the feeding unit 2 and the upper cleaning unit 1 to move between the upper common switching position and the standby position, and to drive the discharging unit 4 and the lower cleaning unit 5 to move between the lower common switching position and the standby position.

[0029] In this embodiment, if Figure 5As shown, the common unit 3 includes a common pipe 9, an upper flange 10 with an upper sealing ring 12 is provided at the upper end of the common pipe 9, and a lower flange 11 with a lower sealing ring 13 is provided at the lower end of the common pipe 9.

The driving component of the feeding unit 2 is connected to the upper conveying pipe 14, and the driving component of the discharging unit 4 is connected to the lower conveying pipe 22.

[0030] In this embodiment, if Figure 2 As shown, the standby positions of the feed unit 2 are evenly distributed in a circular form with the common unit 3 as the center, and the standby positions of the discharge unit 4 are correspondingly arranged below the standby positions of the feed unit 2.

[0034] In this embodiment, the driving components of the feed unit 2 and the discharge unit 4 are both used for driving horizontal movement and up and down movement; the driving components of the upper cleaning unit 1 and the lower cleaning unit 5 are both used for driving up and down movement, so that the upper cleaning unit 1 can be switched between the standby position of the upper cleaning unit 1 and the upper common switching position only by up and down movement, and the lower cleaning unit 5 can be switched between the standby position of the lower cleaning unit 5 and the lower common switching position only by up and down movement, thereby ensuring positioning accuracy.

[0035] Specifically, Figure 6 and Figure 8 As shown, the driving components of the feeding unit 2 and the discharging unit 4 include a horizontal cylinder 15 and a first lifting cylinder 16, wherein a pair of first lifting cylinders 16 are provided, distributed on both sides of the upper conveying pipe 14 and the lower conveying pipe 22; Figure 7 and Fig. 9 As shown, the driving components of the upper cleaning unit 1 and the lower cleaning unit 5 both include a second lifting cylinder 19 , wherein a pair of the second lifting cylinders 19 are arranged and distributed on both sides of the upper cleaning pipe 18 and the lower cleaning pipe 24 .

[0036] like Figure 7 As shown, the upper cleaning unit 1 includes an upper cleaning pipe 18, the diameter of the upper cleaning pipe 18 is the same as the diameter of the upper end of the common pipe 9, the driving component of the upper cleaning unit is connected to the upper cleaning pipe 18, and the upper end of the upper cleaning pipe 18 is provided with an air volume regulating valve 21 and an upper filter 20; Fig. 9 As shown, the lower cleaning unit 5 includes a lower cleaning pipe 24, the diameter of which is larger than the diameter of the lower end of the common pipe 9, the driving component of the lower cleaning unit 5 is connected to the lower cleaning pipe 24, the lower end of the lower cleaning pipe 24 is connected to a cleaning hose 25 with a lower filter 26, and is connected to a negative pressure generating device such as a vacuum pump. When the negative pressure device such as the vacuum pump is started, the common pipe can be fully cleaned to ensure the cleanliness of the pipe, and after cleaning, other materials can be transported accordingly.

[0037] In this embodiment, the common pipe 9, the upper delivery pipe 14, the lower delivery pipe 22, the upper cleaning pipe 18, and the lower cleaning pipe 24 are all hard straight pipes.

[0038] Based on the above settings of this embodiment, the overall structure is simple, the volume is small, the height can be controlled within 1.5M, cylinders and solenoid valves can be used as actuators, and the cost is low. It is better than the existing distribution plate with a height of more than 2 meters, inconvenient maintenance and inspection, expensive price, and incomplete cleaning of public areas.

[0039] In this specification, the utility model has been described with reference to its specific embodiments. However, it is obvious that various modifications and changes can be made without departing from the spirit and scope of the utility model. Therefore, the description and drawings should be regarded as illustrative rather than restrictive.
