[0027] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0028] Example 1: In some embodiments, please refer to the accompanying drawings of the specification. Figure 1-Figure 5 , a check valve cavitation device with a material dividing function, comprising a receiving box 1;

[0029] A partition 2 is fixedly installed in the middle of the storage box 1, and guide cone blocks 8 are symmetrically fixedly installed on the front and rear sides of the top of the partition 2. Discharge inclined plates 9 are symmetrically fixedly installed at both ends of the guide cone block 8. A storage box 4 for receiving materials is provided on the lower side of the discharge end of the discharge inclined plate 9; a through slot 3 for taking and placing the storage box 4 is opened on the side wall of the storage box 1;

[0030] The top of the partition plate 2 is provided with a forward and reverse bending material removal component for separating the valve core from the flow channel, and the top of the storage box 1 is also provided with a cooling auxiliary material removal component.

[0031] The forward and reverse bending material taking assembly includes a bracket 5 and a cross bar 6, and the two cross bars 6 are symmetrically distributed on the left and right sides of the partition 2; the upper end of the bracket 5 is fixedly connected to the middle of the cross bar 6, and the lower end of the bracket 5 is fixedly connected to the partition 2; the outer side of the bracket 5 is also provided with a soft pad 7 to prevent scratching the valve core, and the soft pad 7 can be a rubber cushion layer;

[0032] The distance between the two cross bars 6 is slightly larger than the distance between the valve cores on both sides of the injection molded part near the ends, so that the valve core can be smoothly bent into a positive V shape or an inverted V shape.

[0033] The cooling auxiliary stripping component includes a bracket 10, a fan 11 and a conveying pipe 12. The bracket 10 is fixedly installed on the inner bottom of the storage box 1. The upper end of the bracket 10 is fixedly installed with a fan 11 for blowing air toward the upper injection molded parts; the conveying pipe 12 is fixedly installed on the top of the storage box 1, and the discharge end of the conveying pipe 12 is located above the fan 11 and is tilted upward. The feed end of the conveying pipe 12 is connected to the pump, and the conveying pipe 12 is used to spray refrigerant gas such as dry ice gas onto the fan 11.

[0034] The receiving box 1 is made of transparent plastic material, which makes it easy for the operator to observe the amount of material in the storage box 4.

[0035] The specific working steps of the unwinding equipment are as follows:

[0036] Step 1: Use a material transfer device, such as a robot, to grab the main channel in the middle of the injection molded part and move the injection molded part directly above the fan 11. The fan 11 blows air to the branch channel to cool it down. At the same time, the delivery pipe 12 sprays refrigerant gas to the fan 11 to increase the cooling efficiency, so that the connection between the valve core and the branch channel is quickly cooled and hardened.

[0037] Step 2: Move the injection molded part to the top of the crossbar 6, with the branch channel located in the middle of the two crossbars 6;

[0038] Step 3: The material moving device drives the injection molded part to move vertically downward. During the downward movement of the injection molded part, the valve core is blocked by the cross bar 6 and the branch channel continues to move downward, causing the valve core to bend upward into a positive V shape, and then drives the injection molded part to move upward;

[0039] Step 4: The injection molded part is moved to one side of the partition 2;

[0040] Step 5: The material transfer device moves the valve core on one side of the injection molded part to the bottom of the crossbar 6, and the branch channel is located in the middle of the two crossbars 6 as shown in the figure of the specification. Figure 5 As shown;

[0041] Step 6: The material moving mechanism drives the injection molded part to move vertically upward. During the upward movement of the injection molding part, the valve core is blocked by the cross bar 6 and the branch channel continues to move upward, causing the valve core to bend downward into an inverted V shape. At this time, the connection between the valve core and the channel is broken due to the positive and negative bending, causing the valve cores on both sides to pass through the material guide cone block 8 and fall onto the discharge inclined plate 9, and finally slide into the material storage box 4;

[0042] Step 6: After the material transfer device moves the injection molded part to the other side of the partition 2, steps 4 and 5 are repeated to complete the cavity and material separation operations of the injection molded part.

[0043] In the present invention, by cooling the injection molded part and then bending it twice, the valve core and the flow channel can be smoothly separated, and the automatic cavitation and material separation operations of the check valve core can be completed; the device has a simple structure, low cost, and high stability, which effectively improves production efficiency and solves the problem of difficulty in cavitation of small injection-molded check valve cores.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
