Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical filling equipment technology, and in particular to a protective device for an extruder die head and an extruder. Background Technology

[0002] During the heating process, the filling machine produces an oily substance from the resin raw material, which adheres to the surface of the extruder die head and core. After prolonged heating, carbon deposits are formed. In addition, after the extruder is started, the initial speed is relatively low (due to the characteristics of the filling machine, the initial speed cannot be too high, otherwise it will cause excessive extruder pressure and lead to malfunction). It takes a certain amount of time to gradually increase the speed to a suitable speed. Before the normal speed is reached, the raw material discharged from the die head and core will curl inward and adhere to the die head and core, which will also aggravate the formation of carbon deposits. After a long period of production, a large amount of carbon deposits will adhere to the surface of the die head and core, which can easily cause foreign matter to be detected in the liquid medicine. Utility Model Content

[0025] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0026] The specific structure is as follows: Figure 1 and Figure 2 As shown.

[0027] This embodiment provides a protective device for an extruder die head. The extruder die head has a die core. The protective device includes: a base 1, a lifting rod 2, and a baffle 3. At least one lifting rod 2 is provided on the base 1. Each lifting rod 2 has a baffle 3 connected to its upper end. The baffle 3 is circular and its diameter is smaller than that of the die core. The lifting rod 2 can lift the baffle 3 to abut against the die core. In use, the protective device is placed below the extruder die head. The lifting rod 2 abuts the baffle 3 against the die core, transferring oily substances and material entanglement to the baffle 3, effectively reducing carbon deposits on the die head and die core surface, and preventing the generation of foreign matter in the liquid.

[0028] In this embodiment, the number of lifting rods 2 and baffles 3 corresponds one-to-one with the mold head and mold core, and the diameter of the baffles 3 is 1.5mm smaller than the diameter of the mold core. This satisfies the transfer requirements while avoiding interference with the discharge of raw materials.

[0029] In this embodiment, four lifting rods 2 and four baffles 3 are provided. It should be noted that when multiple lifting rods 2 and baffles 3 are provided, connecting plates can be connected between adjacent baffles 3 to improve stability.

[0030] In the optional technical solution of this embodiment, a positioning groove is provided on the mold core, and a positioning block 4 that cooperates with the positioning groove is provided on the baffle 3. The positioning block 4 is located at the center of the baffle 3 and is inserted into the positioning groove to prevent the baffle 3 from shifting.

[0031] In the optional technical solution of this embodiment, the cross-section of the positioning block 4 is polygonal. This prevents the positioning block 4 from rotating within the positioning groove.

[0032] In the optional technical solution of this embodiment, the lifting rod 2 includes an upper rod body 5 and a lower rod body 6; a baffle 3 is connected to the upper end of the upper rod body 5, and the lower end of the lower rod body 6 is connected to the base 1; the upper rod body 5 and the lower rod body 6 are connected by a thread, so that the upper rod body 5 can be raised or lowered by relative screwing. The height can be adjusted by screwing, which is convenient to use and has a simple structure.

[0033] In the optional technical solution of this embodiment, the lifting rod 2 includes an upper rod body 5 and a lower rod body 6; a baffle 3 is connected to the upper end of the upper rod body 5, and the lower end of the lower rod body 6 is connected to the base 1; the upper rod body 5 and the lower rod body 6 are interlocked, and a spring 7 is provided between the upper rod body 5 and the lower rod body 6 so that the upper rod body 5 can be raised and lowered by the extension and contraction of the spring 7. When the baffle abuts against the mold core, the spring 7 provides an upward force to the upper rod body 5 to ensure that the baffle and the mold core can be pressed tightly; when it needs to be removed, the upper rod body 5 is pulled down to further compress the spring 7, so that the positioning block 4 can be removed from the positioning groove, and the entire protective device can be removed. The operation is simple and the disassembly is convenient. The upper rod 5 has an upper groove 13 at its lower end and a lower groove 14 at its upper end. The lower end of the upper rod 5 can be inserted into the lower groove 14, or the upper end of the lower rod 6 can be inserted into the upper groove 13. A spring 7 is provided between the upper groove 13 and the lower groove 14. The structure is simple and easy to install and manufacture.

[0034] In the optional technical solution of this embodiment, the base 1 includes a top plate 8 and support legs 9 disposed at both ends of the top plate 8 for supporting the top plate 8. The structure is simple and provides stable support. The support legs 9 can be provided with hollowed-out sections 15 to reduce weight, and the top plate 8 can also be provided with hollowed-out sections 15 to reduce weight.

[0035] In an optional technical solution of this embodiment, the base 1 further includes an auxiliary support leg 10 disposed on at least one side of the top plate 8 and used to support the top plate 8. This further improves the stability of the base 1, wherein the auxiliary support leg 10 may be provided with a hollowed-out section 15 to reduce weight.

[0036] In an optional technical solution of this embodiment, the base 1 is provided with an elongated hole 11, and the lifting rod 2 is connected to the elongated hole 11. The position of the lifting rod 2 can be easily adjusted through the elongated hole 11.

[0037] In the optional technical solution of this embodiment, a connecting plate 12 is provided at the lower end of the lifting rod 2, and the connecting plate 12 is connected to the base 1. The lifting rod 2 is connected to the top plate 8 of the base 1 through the connecting plate 12, which is stable and convenient.

[0038] This embodiment provides an extruder including the aforementioned protective device for the extruder die. Therefore, the technical advantages and effects achieved by the extruder include those achieved by the aforementioned protective device for the extruder die, which will not be elaborated here.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
