[0037] like Figure 1-4 As shown, the utility model provides an automatic feeding mechanism for injection molding particles, which can be used for feeding injection molding particles.

[0038] Specifically, the automatic feeding mechanism for injection molding particles provided by the embodiment of the utility model includes a barrel 10, a first connecting part 11 and a docking structure 20, wherein the barrel 10 is provided with an outlet and a control valve 12 for controlling the opening and closing of the outlet; and the first connecting part 11 includes a first end and a second end arranged opposite to each other, the first end is connected to the outside of the outlet of the barrel 10, and can be connected with the outlet when the outlet is opened; the docking mechanism 20 is provided with a second connecting part 21 suitable for being adapted to be connected with the second end of the first connecting part 11; a suction mechanism connected with the second connecting part 21 is also provided in the docking mechanism 20; the barrel 10 can be transferred between the silo and the docking mechanism 20, and can be connected with the second connecting part 21 through the first connecting part 11 when transferred to the docking mechanism 20. In the connected state, the control valve 12 can cooperate with the suction mechanism to adsorb the injection molding particles in the barrel 10 into the docking mechanism 20.

[0039] The barrel 10 is provided with a cavity and an outlet connected to the cavity, and a control valve for controlling the opening and closing of the outlet is also provided at the outlet, wherein when the control valve closes the outlet, the cavity can be used to accommodate injection molding granular materials, and when the control valve opens the outlet, the injection molding granular materials can be discharged from the outlet.

[0040] A first connecting portion 11 is further disposed on the outer side of the barrel 10 . A first end of the first connecting portion 11 is connected to the outlet and can be communicated with the cavity of the barrel 10 when the outlet is opened.

[0041] The docking mechanism 20 can be a pre-processing mechanism for injection molding granular materials, wherein the docking mechanism has a second connecting portion 21, and can be connected to the first connecting portion 11 through the second connecting portion 21, thereby realizing the connection between the docking mechanism 20 and the barrel 10. In the connected state, the injection molding granular materials from the barrel can be transported to the injection molding equipment after being processed by the docking mechanism.

[0042] The automatic feeding structure 100 for injection molding particles provided by the embodiment of the utility model is provided with a barrel 10 having a first connection part 11 and a control valve 12, and a docking mechanism 20 having a second connection part 21 and a suction mechanism. When the barrel 10 carrying the injection molding particles is transferred to the docking structure and connected to the second connection part 21 through the first connection part 11, when the control valve 12 is opened and the suction mechanism is running, the injection molding particles can be sucked from the silo into the docking mechanism 20, thereby realizing the feeding of the injection molding particles. The above-mentioned feeding structure 100 is simple and effective, so the cost is low, and the above-mentioned structure can realize automatic control, so it can not only shorten the feeding time, but also liberate manpower, thereby ensuring the feeding efficiency.

[0043] In a specific embodiment of the present invention, the first connecting portion 11 includes a first connecting tube, and the second connecting portion 21 is a second connecting tube. The first connecting tube and the second connecting tube are plugged in and connected.

[0044] Specifically, the first connecting tube and the second connecting tube are both arranged horizontally, so that when the first connecting tube and the second connecting tube are plugged in, they only need to be aligned and moved horizontally to achieve the plugging.

[0045] The first connecting tube can be inserted into the second connecting tube, or the second connecting tube can be inserted into the first connecting tube.

[0046] The above arrangement of the present embodiment makes the connection between the barrel 10 and the docking structure simple and effective, which is not only low-cost but also conducive to simplifying the loading operation.

[0047] In a specific implementation manner of the utility model, the second end of the first connecting tube is arranged in a bell-mouth shape.

[0048] In this embodiment, the second connecting tube is plugged into the first connecting tube to realize the connection between the barrel 10 and the docking mechanism 20, and the plug-in end of the first connecting tube is set in a bell-mouth shape, which can expand the alignment range of the first connecting tube and the second connecting tube, thereby facilitating the docking operation of the first connecting tube and the second connecting tube.

[0049] In a specific embodiment of the present invention, the control valve 12 includes a telescopic mechanism and a baffle 13 connected to each other. The baffle 13 is arranged between the outlet and the first end of the first connecting part 11, and can move under the action of the telescopic mechanism to block or open the outlet.

[0050] The telescopic mechanism can be a piston cylinder or a motor drive structure. Taking the piston cylinder as an example, the piston cylinder is connected to the barrel 10, and the piston rod of the piston cylinder is connected to the baffle 13, so the baffle 13 can be driven to move. The baffle 13 is arranged between the outlet and the first end of the first connecting part 11. Among them, when the piston rod moves in the direction away from the first connecting part, it can drive the baffle 13 to move to open the outlet, and when the piston rod moves in the direction close to the first connecting part, it can drive the baffle 13 to move to close the outlet. When the outlet is open, the inner cavity of the barrel 11 is connected to the first connecting part 11 through the outlet, so that the injection particles can be discharged from the barrel 10. When the outlet is closed, the channel between the inner cavity of the barrel 11 and the first connecting part 11 is closed, and the injection particles cannot be discharged, so that the unloading control is realized.

[0051] In this embodiment, the above arrangement makes the structure of the control valve 12 simple and effective.

[0052] In a specific embodiment of the present invention, the outlet is located at the bottom surface of the barrel, and the telescopic mechanism is arranged on the outside of the barrel and is suitable for driving the baffle 13 to move horizontally to open and close the outlet.

[0053] Optionally, the outlet is located on the side of the barrel 10, and the plane where the baffle 13 is located is arranged along the vertical direction.

[0054] Optionally, the outlet is located at the bottom surface of the barrel 10, and the plane where the baffle 13 is located is arranged in the horizontal direction. In this way, the transfer mechanism (not shown in the figure) can be effectively avoided, thereby preventing the baffle 13 from interfering with the transfer mechanism.

[0055] In this embodiment, the lower end of the barrel is arranged in a retracted shape that protrudes outward, and the outlet is arranged at the end surface of the lower end, so that the injection molding particles in the barrel 10 can be easily discharged.

[0056] The baffle is a flat plate structure, which is horizontally arranged outside the outlet and specifically clamped between the outlet and the first end of the first connecting portion 11. The telescopic mechanism is arranged outside the barrel and can drive the baffle to move horizontally to open and close the outlet.

[0057] In a specific embodiment of the utility model, the control valve 12 further includes an elastic member 14, one end of the elastic member is connected to the baffle 13, and the other end is connected to the first connecting portion 11 or the barrel 10. The elastic member 14 is reset to drive the baffle 13 to switch the outlet from the open state to the closed state. By providing the elastic member 14, the closing control of the outlet can be ensured.

[0058] Specifically, the elastic member 14 may be a tension spring, one end of which is connected to the baffle 13, and the other end of which is opposite to the baffle and is connected to the first connection portion 11 or the barrel corresponding to the position of the first connection portion 11. Therefore, under normal conditions, the spring can pull the baffle 13 to the side of the first connection portion 11 so that the baffle 13 closes the outlet of the barrel 10. When the barrel reaches the specified position, the piston rod pushes the baffle 13, the spring is pulled open, the barrel outlet is opened, and the suction mechanism sucks the material; when the suction mechanism detects that there is no material three times, the cylinder is retracted, the spring contracts to pull back the baffle 13, and the barrel outlet is closed.

[0059] In a specific embodiment of the present invention, a limit plate 15 is further provided at the end of the baffle 13 adjacent to the first connecting portion 11, and the limit plate 15 contacts the barrel 10 or the telescopic mechanism to limit the movement range of the baffle 13. In this way, the baffle 13 can be limited by the limit plate 15 to prevent the baffle 13 from falling out under the action of the telescopic mechanism.

[0060] In a specific embodiment of the present invention, the docking mechanism 20 is further provided with a drying cylinder, which is arranged at the other end of the suction mechanism relative to the second connecting portion 21. Specifically, the injection molding particles enter the drying cylinder from the barrel 10 under the suction action of the suction mechanism for the next step of processing.

[0061] In a specific embodiment of the present invention, a support 30 for placing the barrel 10 is further included, and the transfer mechanism is connected to the support 30 to transfer the barrel 10. The support 30 can be provided to facilitate the connection of the transfer mechanism.

[0062] Specifically, a space suitable for accommodating the transfer mechanism is provided below the bracket 30 and the docking mechanism 20. The transfer mechanism moves to the corresponding space and is connected to the bracket 30 or the docking mechanism 20 through the supporting structure, thereby driving the bracket 30 and the docking mechanism 20 to move.

[0063] Optionally, the bracket 30 and the barrel 10 are arranged as an integral structure.

[0064] Optionally, the transfer mechanism is an automated guided vehicle or an unmanned guided vehicle (AGV), which can be used for the transfer of the barrel 10 , thereby moving the barrel 10 between the silo and the docking mechanism 20 , and can also be used for the transfer of the docking mechanism 20 .

[0065] The second aspect of the utility model also provides an injection molding device, including any one of the above-mentioned automatic feeding mechanisms for injection molding particles. Specifically, the automatic feeding structure 100 for injection molding particles refers to the above-mentioned embodiments, and will not be described one by one here. Since the injection molding device of this embodiment includes the automatic feeding mechanism for injection molding particles described in all the above-mentioned embodiments, it also has at least the beneficial effects of the above-mentioned automatic feeding mechanism for injection molding particles.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
