Description

Technical Field

[0001] This utility model relates to the field of heating device technology, and in particular to a heating device for an amino molding compound extruder. Background Technology

[0002] Amino molding compounds are thermosetting plastics, mainly made by mixing amino resins with fillers, curing agents, release agents, pigments and other additives.

[0003] Amino molding compounds often require extrusion during production. During the extrusion process, the raw material needs to be heated at the barrel. However, some traditional extruder heating devices typically use resistance heating elements that wrap around the barrel. This method results in a relatively concentrated temperature, which can easily lead to uneven heating and affect the melting effect of the material. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a heating device for an amino molding compound extruder.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A heating device for an amino molding compound extruder includes a heating cover one and a heating cover two. The heating cover one and the heating cover two are both semi-circular and are spliced ​​together by fasteners to form a cylindrical structure. The heating cover one and the heating cover two are installed on the outer wall of the barrel in the middle of the extruder body.

[0007] The inner walls of heating cover one and heating cover two are equipped with heat-conducting plates. The inner side of the heat-conducting plates is connected to the electric heating plate, and the side away from the electric heating plate is provided with a heat-insulating plate.

[0008] A mounting roller is connected between heating cover one and heating cover two. A rotating wheel is rotatably mounted in the middle of the mounting roller via a bearing component. The rotating wheel is limited and assembled in the mounting rail set on the upper part of the extruder body.

[0009] In addition, a preferred structure is that the upper and lower ends of the heating cover are each equipped with a connecting seat, the two sides of the connecting seat are provided with mounting holes for fasteners, and the middle of the connecting seat is provided with a snap-fit ​​hole.

[0010] In addition, the preferred structure is that the upper and lower ends of the heating cover are both equipped with connecting seats, the two sides of the connecting seats are provided with mounting holes for fasteners, the middle part of the connecting seat is provided with a snap-fit ​​groove, and the inner wall of the snap-fit ​​groove is provided with multiple slots in a ring.

[0011] Furthermore, in a preferred configuration, one end of the mounting roller is fitted with a locking block to engage with a locking groove, and the other end of the mounting roller is fitted with a locking connector to engage with a locking hole.

[0012] In addition, a preferred structure is that a mounting cover is fastened to the side away from the snap-fit ​​hole by a second locking bolt, and a first locking bolt is screwed into the middle of the mounting cover, with one end of the first locking bolt extending into the interior of the mounting cover and pressing against the mounting roller.

[0013] In addition, a preferred structure is that the upper part of the extruder body is provided with an installation rail, which is located directly below the barrel. An installation groove is opened in the middle of the installation rail, and multiple convex rails are installed on the bottom wall of the installation groove. The convex rails correspond to and fit with the annular groove opened on the rotating wheel.

[0014] The beneficial effects of this utility model are as follows:

[0015] In this invention, a heating cylinder assembly is formed by heating cover one and heating cover two. The bottom of the heating cylinder assembly is formed by a moving mechanism consisting of components such as mounting rollers and rotating wheels. It works in conjunction with the mounting rail to achieve free movement, thereby allowing the heating cover to slide flexibly and precisely heat different sections. This solves the problem of uneven heating caused by traditional integrated heating, effectively improves heating efficiency, and ensures production efficiency. 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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-7 A heating device for an amino molding compound extruder includes a heating cover 2 and a heating cover 3. The heating cover 2 and the heating cover 3 are both semi-circular and are spliced ​​together by fasteners 5 to form a cylindrical structure. The heating cover 2 and the heating cover 3 are installed on the outer wall of the barrel 11 in the middle of the extruder body 1.

[0026] A screw conveyor mechanism is installed inside the barrel 11 in the middle of the extruder body 1. The material is conveyed through the barrel 11 and the melting operation is completed at the barrel 11.

[0027] The heat generated by heating hood 1 (2) and heating hood 2 (3) is transferred to the material inside the barrel 11.

[0028] Heat-conducting plates 10 are installed on the inner walls of heating cover 1 2 and heating cover 2 3. The inner side of the heat-conducting plate 10 is connected to the electric heating plate 9, and the side away from the electric heating plate 9 is provided with a heat-insulating plate 8.

[0029] A mounting roller 6 is connected between heating cover 1 (2) and heating cover 2 (3). A rotating wheel 61 is rotatably mounted in the middle of the mounting roller 6 via a bearing. The rotating wheel 61 is limited and assembled in the mounting rail 4 set on the upper part of the extruder body 1. The rotating wheel 61 is connected to the mounting rail 4 to realize the movement function of heating cover 1 (2) and heating cover 2 (3).

[0030] The upper and lower ends of the heating cover 2 are equipped with connecting seats 21. The connecting seats 21 have mounting holes on both sides for mounting fasteners 5, and the middle part of the connecting seats 21 has a snap-fit ​​hole 211.

[0031] The upper and lower ends of the heating cover 2 3 are equipped with connecting seats 2 31. The two sides of the connecting seats 2 31 are provided with mounting holes for fasteners 5. The middle part of the connecting seat 2 31 is provided with a snap-fit ​​groove 311. The inner wall of the snap-fit ​​groove 311 is provided with multiple slots in a ring.

[0032] The heating cover 2 and heating cover 3 are fastened together by fasteners 5, namely nuts and bolts, to form a heating cylinder.

[0033] One end of the mounting roller 6 is equipped with a locking block 63 to engage with the locking groove 311. The inner wall of the locking groove 311 has multiple grooves that fit the locking block 63. The locking block 63 is inserted into the locking groove 311.

[0034] The other end of the mounting roller 6 is fitted with a snap connector 62 to mate with the snap connector hole 211.

[0035] On the side away from the snap-fit ​​hole 211, a mounting cover 7 is fastened with a second locking bolt 72. A first locking bolt 71 is screwed into the middle of the mounting cover 7. One end of the first locking bolt 71 extends into the interior of the mounting cover 7 and presses against the mounting roller 6. The pressing force is used to press the mounting roller 6, so that it is firmly installed in the snap-fit ​​hole 211.

[0036] An installation rail 4 is provided on the upper part of the extruder body 1. The installation rail 4 is located directly below the barrel 11. An installation groove 41 is provided in the middle of the installation rail 4. Multiple convex rails 42 are installed on the bottom wall of the installation groove 41. The convex rails 42 correspond to and fit with the annular groove 611 opened on the rotating wheel 61.

[0037] In this embodiment, heating cover 1 2 and heating cover 2 3 are spliced ​​into a cylindrical body, and the connecting seat 1 21 and connecting seat 2 31 on the upper part of heating cover 1 2 and heating cover 2 3 are connected by fasteners 5. The fasteners 5 are then passed through the connecting seat 1 21 on the lower part of heating cover 1 2 and the mounting groove 41 in the middle of the mounting rail 4 in sequence, so that the fasteners 5 are connected with the connecting seat 2 31 on the lower part of heating cover 2 3. At this time, heating cover 1 and heating cover 2 3 are spliced.

[0038] At this time, the mounting roller 6 is passed through the snap-fit ​​hole 211 in the middle of the connecting seat 1 21 and snap-fitted with the snap-fit ​​groove 311 in the middle of the connecting seat 2 31. Then, the mounting roller 6 is continuously pushed in, causing the snap-fit ​​connector 62 on one side of the mounting roller 6 to snap-fit ​​with the snap-fit ​​hole 211, thus completing the connection operation between the mounting roller 6 and the connecting seat 1 21 and the connecting seat 2 31.

[0039] Then, by tightening the second bolt 72, the mounting cover 7 is installed on the outside of the snap-fit ​​hole 211 to complete the overall assembly of the heating mechanism.

[0040] During the assembly process of the mounting roller 6, the mounting roller 6 passes through the mounting groove 41 in the middle of the mounting rail 4, and the rotating wheel 61 in the middle of the mounting roller 6 is connected with the convex rail 42 in the middle of the mounting rail 4 to form a moving mechanism.

[0041] In practical applications, any number of heating covers 1 and 2 and heating covers 3 can be assembled to form multiple heating zones, thereby accurately heating the materials in each zone to a specified temperature, forming a distributed heating mechanism.

[0042] Meanwhile, during the assembly of heating cover 1 2 and heating cover 2 3, before the fastener 5 is completely tightened, the heating cover 1 2 and heating cover 2 3 can be slidably adjusted on the mounting rail 4 by setting the mounting roller 6 and rotating wheel 61, so as to adjust the heating area.

[0043] At the same time, the fasteners 5 can be slightly loosened during the heating process, so that the heating cover 2, heating cover 3 and the outer wall of the barrel 11 are in a movable gap. At this time, the movement and adjustment operation can still be achieved through the mounting rail 4, which can quickly move the heating position and ensure heating stability.

[0044] During the use of heating cover 1 2 and heating cover 2 3, the heating cover 1 2 and heating cover 2 3 are powered by an external power supply. The electric heating plate 9 inside generates heat when energized, and the heat conduction plate 10 conducts heat to the outer wall of the barrel 11.

[0045] After the fastener 5 is fully tightened, due to the squeezing friction between the heat-conducting plate 10 and the barrel 11, the rotating wheel 61 cannot drive the heating cover mechanism to move, thus ensuring static stability.

[0046] It should also be noted that the specific working principles of the extruder body 1 that are not explained in detail above are common knowledge to those skilled in the art and will not be explained further.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
