Description

Technical Field

[0001] The utility model relates to the technical field of extruder cooling devices, in particular to a cooling mechanism for a long glass fiber polypropylene extruder. Background Art

[0002] Long glass fiber polypropylene is a thermoplastic composite material, which is often composed of polypropylene resin and long glass fibers, in which the long glass fibers are evenly dispersed in the polypropylene matrix, thus giving the composite material excellent mechanical properties such as high strength, high stiffness and good impact resistance. Because long glass fiber polypropylene composites combine the light weight, chemical resistance and easy processing characteristics of polypropylene with the high strength and thermal stability of glass fibers, it is very popular in various industrial applications.

[0003] Most long glass fiber polypropylene is processed and produced by extrusion process. During the extrusion process, an extruder is needed to mix the long glass fiber and polypropylene resin during the extrusion process. During the extrusion process, the screw rotates in the barrel to transport, compact and melt the material. A lot of heat will be generated in this process. If it is not effectively cooled, the temperature will be too high, affecting the plasticization and extrusion quality of the material, and may even damage the equipment.

[0004] At present, the cooling method of long glass fiber polypropylene extruders is often air cooling, using multiple fans to remove heat through air flow. However, when using fans to cool the extrusion barrel of the extruder, there are often dead corners for blowing, and the cooling degree of each position of the extrusion barrel is inconsistent.

[0005] In view of this, a cooling mechanism for a long glass fiber polypropylene extruder is proposed. Utility Model Content

[0008] Furthermore, a sliding seat is slidably provided on the base, the turntable is rotatably installed on the sliding seat, a driving motor is fixedly connected to the sliding seat, a gear is fixedly connected to the output end of the driving motor, a gear is fixedly connected to the turntable, and the gear ring is meshingly connected with the gear, so that when the gear rotates, it can drive the turntable to rotate and drive the cooling component to rotate.

[0009] Furthermore, a T-shaped swivel with a T-shaped cross section is fixedly connected to the turntable, and a sliding groove matching the size of the T-shaped swivel is provided on the sliding seat.

[0010] Furthermore, an electric push rod is fixedly connected to the base, and the extended end of the electric push rod is fixedly connected to the sliding seat. When the extended end of the electric push rod is retracted or extended, the sliding seat and the cooling component are driven to move along the axial direction of the extrusion barrel to complete the multi-directional cooling of the extrusion barrel by the cooling component.

[0011] Furthermore, two of the brackets are provided, and the two brackets are symmetrically arranged at two ends of the extrusion cylinder, and the cooling component is arranged between the two brackets.

[0025] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-7 .

[0027] The utility model discloses a cooling mechanism for a long glass fiber polypropylene extruder, comprising a base 1 and an extruder body 2 arranged above the base 1, the extruder body 2 comprising an extrusion barrel 21 and a plurality of brackets 24 for supporting the extrusion barrel 21, the extrusion barrel 21 being provided with a feeding port 22 and a discharging port 23, the extrusion barrel 21 being provided with a cooling component 3 on the outside, the cooling component 3 comprising a plurality of mounting plates 31 sleeved on the outside of the extrusion barrel 21 and a plurality of connecting rods 32 for connecting the plurality of mounting plates 31, a fan 39 being detachably provided between two adjacent mounting plates 31, a turntable 33 being fixedly connected to the middle of the connecting rod 32, the turntable 33 being used for driving the cooling component 3 to rotate when rotating so as to perform multi-directional cooling on the extrusion barrel 21.

[0028] Among them, the fan 39 and the mounting plate 31 bracket 24 can be connected in various ways such as bolt connection or slot connection. In the present embodiment, the fan 39 is arranged at intervals in the channel formed by the plurality of mounting plates 31. During specific use, the number of fans 39 can be adjusted according to the cooling degree required by the extruder.

[0029] In addition, a sliding seat 35 is slidably provided on the base 1, and the turntable 33 is rotatably installed on the sliding seat 35. A T-shaped swivel 331 with a T-shaped cross-section is fixedly connected to the turntable 33. A sliding groove 306 with a size matching the T-shaped swivel 331 is provided on the sliding seat 35. A driving motor 36 is fixedly connected to the sliding seat 35, and a gear 37 is fixedly connected to the output end of the driving motor 36. A toothed ring 34 is fixedly connected to the turntable 33, and the toothed ring 34 is meshed with the gear 37, so that when the gear 37 rotates, it can drive the turntable 33 to rotate, thereby driving the cooling component 3 to rotate.

[0030] That is to say, when the sliding seat 35 moves, the turntable 33 will be driven to move, and the cooling component 3 will also be driven to move. When the sliding seat 35 moves, since the turntable 33 and the sliding seat 35 are slidingly arranged, the turntable 33 can move horizontally with the sliding seat 35 and drive the cooling component 3 to rotate under the meshing action of the gear 37 and the tooth ring 34.

[0031] Specifically, if Figure 1 or Figure 2 As shown, an electric push rod 38 is fixedly connected to the base 1, and the protruding end of the electric push rod 38 is fixedly connected to the sliding seat 35. The electric push rod 38 is used to drive the sliding seat 35 and the cooling component 3 to move along the axial direction of the extrusion cylinder 21 when the protruding end is contracted or extended to complete the multi-directional cooling of the extrusion cylinder 21 by the cooling component 3, that is, the electric push rod 38 is used to control the movement of the sliding seat 35.

[0032] In addition, in the present embodiment, two brackets 24 are provided, and the two brackets 24 are symmetrically arranged at both ends of the extrusion tube 21, and the cooling component 3 is arranged between the two brackets 24. It should be noted that such arrangement is to prevent the brackets 24 from affecting the movement and rotation of the cooling component 3, and to fully expose the outer surface of the extrusion tube 21 so that it can be exposed to more cooling effects brought by the cooling component 3.

[0033] It should be noted that in order to keep the cooling effect at various angles of the extruder barrel 21 basically consistent when the cooling component 3 rotates, however, the fans 39 are all provided with frames, so a single rotation of the fan 39 will still make the position of the extruder barrel 21 blocked by the frame of the fan 39 unable to receive sufficient cooling, so it is necessary to enable multiple fans 39 to slide along the surface of the extruder barrel 21 with the sliding seat 35.

[0034] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
