Abstract
Description
Technical Field
[0001] This utility model relates to the field of ball valve injection molding machine technology, and more specifically, it relates to a material storage device for a ball valve injection molding machine. Background Technology
[0002] Ball valve injection molding machines are widely used in the production of ball valves, pipe fittings and other precision plastic products. Their main working principle is to inject molten plastic into the mold through the injection system of the injection molding machine, and then cool and solidify it to form the parts of the required shape.
[0003] In the production process of ball valve injection molding machines, the storage, transportation and supply of raw materials play a crucial role;
[0004] Currently, most of the material storage devices used in injection molding machines on the market are simple storage boxes or hoppers, which often have some problems in use.
[0005] For example, most storage devices on the market currently only use stirring or other methods to mix materials. However, the existing stirring methods often have unsatisfactory mixing effects. The method of rotating in the same direction often requires a long time to mix the materials, so its mixing efficiency needs to be improved.
[0006] Therefore, we have developed a material storage device with high mixing efficiency for ball valve injection molding machines. Utility Model Content
[0007] To achieve the above objectives, the present invention provides the following technical solution:
[0008] A material storage device for a ball valve injection molding machine includes a storage tank body. A connecting positioning ring is installed on the inner wall of the storage tank body to divide the inner wall of the storage tank body. An insertion limiting port is opened at the bottom of the storage tank body, and a seepage discharge port is opened at the top of the insertion limiting port. The seepage discharge port is opened in the inner cavity of the storage tank body. A fixed shaft is installed inside the storage tank body. A connecting sleeve is movably sleeved on the surface of the fixed shaft. An array mixing rod is connected to the surface of the connecting sleeve. The array mixing rod is installed between the connecting positioning ring and the connecting sleeve. The connecting positioning ring is used to fix the rotation of the array mixing rod.
[0009] Furthermore, a positioning and gathering ring is sleeved on the surface of the array mixing rod, a tension gathering spring is provided on the surface of the positioning and gathering ring, an engaging groove is opened inside the connecting positioning ring, and a top support impact block is installed on the surface of the connecting positioning ring.
[0010] Furthermore, the protrusion direction of the top support impact block and the rotation direction of the array mixing rod are set in opposite directions.
[0011] Furthermore, a convergence spring is installed inside the array mixing rod, and a rotating cutting strip is wound around the surface of the convergence spring. The rotating cutting strip enters and exits between the two positioning convergence rings, and the two positioning convergence rings are set at an angle by the rotating cutting strip. A torsion spring is installed inside the positioning convergence ring.
[0012] Furthermore, the surface of the array mixing rod is provided with a flow guide groove, which is used to increase the contact area between the surface of the array mixing rod and the material. The surface of the array mixing rod is also wound with a heating wire, which is independently powered. The power supply for the heating wire is installed inside the array mixing rod.
[0013] Furthermore, the storage tank body is generally conical, and the array mixing rod is used to regulate the internal temperature of the storage tank body.
[0014] In summary, this utility model has the following beneficial effects:
[0015] By setting up an array of mixing rods, the internal materials of the storage tank are mixed in layers. Furthermore, the area between the two layers of array mixing rods is further cut by a rotating cutting belt, thereby effectively enhancing the mixing efficiency of the storage tank. The heating effect of the array mixing rods also extends the solidification time of the materials. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0025] Example:
[0026] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.
[0027] Please see Figure 1-5 This utility model provides a technical solution: a material storage device for a ball valve injection molding machine, such as... Figure 1-5 As shown, the system includes a storage tank body 1. A connecting positioning ring 2 is installed on the inner wall of the storage tank body 1. The connecting positioning ring 2 is used to divide the inner wall of the storage tank body 1. An insertion limiting port 8 is opened at the bottom of the storage tank body 1. A seepage discharge port 9 is opened at the top of the insertion limiting port 8. The seepage discharge port 9 is opened in the inner cavity of the storage tank body 1. A fixed shaft 3 is installed inside the storage tank body 1. A connecting locking sleeve 7 is movably sleeved on the surface of the fixed shaft 3. An array mixing rod 4 is connected to the surface of the connecting locking sleeve 7. The array mixing rod 4 is installed between the connecting positioning ring 2 and the connecting locking sleeve 7. The connecting positioning ring 2 is used to fix the rotation of the array mixing rod 4.
[0028] In this embodiment: With this configuration, when the material needs to be mixed inside the storage tank 1, the motor inside the fixed shaft 3 can be started. During the start-up process of the motor inside the fixed shaft 3, the internal rotating shaft of the fixed shaft 3 will drive the connecting sleeve 7 to rotate, thereby driving the array mixing rod 4 to rotate as well. During the rotation of the fixed shaft 3 and the connecting positioning ring 2, the array mixing rod 4 can effectively mix the material inside the storage tank 1. We set the upper and lower array mixing rods 4 to start in different rotation directions. Therefore, during the rotation of the two array mixing rods 4, there will be a stirring vortex between the two array mixing rods 4. Under the influence of the vortex, the array mixing rods 4 can effectively stir the inside of the fixed shaft 3, thereby ensuring the mixing effect of the storage tank 1. Through such stirring, the air bubbles in the mixing process will float to the top. During this process, the material is leaked downwards through the seepage discharge port 9 to ensure that no air bubbles enter the material.
[0029] like Figure 1-5 As shown, a positioning and gathering ring 5 is sleeved on the surface of the array mixing rod 4, a tension gathering spring 6 is provided on the surface of the positioning and gathering ring 5, a locking groove 11 is opened inside the connecting positioning ring 2, and a top support impact block 10 is installed on the surface of the connecting positioning ring 2.
[0030] In this embodiment, the device is configured in such a way that the collision force between the material and the inner wall of the storage tank 1 during the mixing process is effectively increased by the top support impact block 10. It should be noted that the protrusion direction of the top support impact block 10 is opposite to the rotation direction of the array mixing rod 4. This configuration ensures the collision force of the material inside the storage tank 1, while the locking groove 11 also ensures the stability of the array mixing rod 4 during rotation.
[0031] like Figure 1-5 As shown, a gathering spring rod 12 is installed inside the array mixing rod 4. A rotating cutting strip 13 is wound around the surface of the gathering spring rod 12. The rotating cutting strip 13 enters and exits between two positioning gathering rings 5. The two positioning gathering rings 5 are set at an angle by the rotating cutting strip 13. A torsion spring is installed inside the positioning gathering ring 5.
[0032] In this embodiment, by setting it up in this way, during the rotation of the array mixing rod 4, the positioning and gathering ring 5 can effectively connect the rotating cutting belt 13 to cut the material between the two array mixing rods 4. In the gap between the upper and lower array mixing rods 4, the rotating cutting belt 13 can cut the eddies between them, preventing excessively large eddies from affecting the mixing effect during the mixing process. This setting adds a mixing interlayer between the array mixing rods 4, effectively ensuring the device's performance. Furthermore, during the rotation of the array mixing rods 4, since the array mixing rods 4 rotate in the opposite direction, the number of rotations of the array mixing rods 4 may be limited. The winding length of the rotating cutting strip 13 is adjusted. Therefore, in actual use, by punching a hole at the front end of the array mixing rod 4, a portion of the rotating cutting strip 13 is placed inside the connecting positioning ring 2, and then the opening is made by engaging the slot 11. In this way, the rotating cutting strip 13 is placed in the storage tank 1 to form a cycle, thus ignoring the limited rotation of the array mixing rod 4. If not set up in this way, by adjusting the rotation direction of the array mixing rod 4 to reciprocating rotation, within the specified number of turns, the mixing effect of the storage tank 1 can be enhanced while the array mixing rod 4 can be used normally, thereby achieving the purpose of enhancing the mixing operation of the storage tank 1.
[0033] like Figure 1-5 As shown, the surface of the array mixing rod 4 is provided with a guide groove 14, which is used to increase the contact area between the surface of the array mixing rod 4 and the material. The surface of the array mixing rod 4 is also wound with a heating wire, which is independently powered. The power supply for the heating wire is installed inside the array mixing rod 4.
[0034] In this embodiment, through this configuration, during the use of the device, the guide channel 14 effectively creates a certain vortex in the array mixing rod 4 during its stirring process, thereby enhancing the mixing effect. Furthermore, this needs to be consistent with the following description: the storage tank 1 is generally conical in shape, and the array mixing rod 4 is used to regulate the internal temperature of the storage tank 1. It should be noted that while the storage tank 1 is intended for easy material loading, considering its conical shape, the material near the bottom of the storage tank 1 is more prone to condensation. Currently, the available method is... The bottom of the storage tank 1 is heated by external methods, including but not limited to water immersion and baking. However, the bottom of the storage tank 1, being conical, has a large heating area and is relatively easy to heat up. But the cylindrical middle part is difficult to heat the material inside through this operation. Therefore, in actual use, we embed heating wires on the surface of the array mixing rod 4 so that it can maintain the temperature of the material through friction and its own heating properties during the stirring process, preventing it from condensing and becoming unusable. Considering this property, we directly set a power supply inside the array mixing rod 4 to start the heating component, which can effectively maintain the daily storage of the storage tank 1, thus facilitating the use of the device.
