Description

Technical Field

[0001] The utility model relates to the technical field of nylon material granulation, and more specifically, to a granulator used for processing glass fiber reinforced nylon material. Background Art

[0002] Glass fiber reinforced nylon is a composite material made by adding glass fiber, toughening agent and other blending materials to nylon. Its mechanical properties increase with the increase of glass fiber content, and the tensile strength and flexural strength of the material are greatly improved. The optimal ratio is: adding 30% to 35% glass fiber and 8% to 12% toughening agent, and the comprehensive mechanical properties of the obtained material are the best. Glass fiber reinforced nylon has the characteristics of high temperature resistance, good dimensional stability, good toughness, good insulation, good corrosion resistance and high mechanical strength. After the glass fiber and nylon are fused, they need to be processed into particles for storage, so a granulator for processing glass fiber reinforced nylon materials is needed.

[0003] After searching, for example, the Chinese patent application with application number 201620047231.2 discloses a granulator for producing nylon materials, in which a cooling shell is added to the outer side of the die head, and the rod material in the die hole is preliminarily cooled by a cooling tube with an annular spiral structure. Since the flow direction of the coolant in the cooling tube is opposite to the extrusion direction in the die hole, the cooling effect is enhanced. In addition, the existing air cooling system makes the cooling of the extruded rod material more complete, effectively avoiding the sticking and agglomeration of the extruded rod material or the cut pellets, and improving the quality of the produced nylon pellets; the existing granulator also adds a vibrating screen, and the cut pellets fall onto the vibrating screen, and the vibration of the vibrating screen is controlled by a vibrating motor The nylon particles that cannot be dispersed are isolated at the upper end of the vibrating screen through the filtration of the vibrating screen, thereby ensuring the quality of the produced nylon particles. A pelletizing groove is also provided on the knife body. Through the different slopes of the first groove slope and the second groove slope, since the length of the first groove slope is smaller than the diameter of the die hole, during pelletizing, the cross section of the rod material transitions from the first groove slope to the second groove slope, so that the nylon that is completely attached to the knife surface leaves the knife surface, thereby avoiding the situation where the cross section of the nylon particles sticks to the cutter surface due to incomplete cooling of the center of the nylon rod material, which not only improves the quality of the nylon particles, but also keeps the cutter surface clean, making it more convenient to use.

[0004] However, since the cooling tube is arranged on the outer surface of the die head, the die head is cooled. When the nylon material passes through the die hole, it will solidify prematurely, resulting in irregular cut particles during cutting, and two cut surface grooves are formed for particle forming, thereby affecting the efficiency of particle forming. In order to solve the above problems and defects, it is necessary to propose a granulator for processing glass fiber reinforced nylon materials that can increase production efficiency.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in 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. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in the field of nylon material granulation without creative work are within the scope of protection of the utility model.

[0028] like Figure 1 and 2 As shown, the utility model provides a granulator for processing glass fiber reinforced nylon material, including a transmission box 1: a die head 12 is fixedly provided on one side of the transmission box 1, a molding processing box 4 is fixedly provided on one side of the die head 12, a discharge port 9 is fixedly provided on the lower end of the molding processing box 4, a rotating motor 5 is fixedly connected to one side of the transmission box 1 through a flange, the output end of the rotating motor 5 movably passes through one side of the transmission box 1, and a conveying auger 11 is fixedly provided on the output end of the rotating motor 5; a heating cylinder 10 is fixedly provided on the inner side of the transmission box 1, a temperature controller 8 is fixedly provided on one side of the transmission box 1, a feed hopper 6 is fixedly provided on the upper end of the transmission box 1, and a fixing frame 7 is fixedly provided on the outer surface of the transmission box 1;

[0029] like Figure 3 As shown, a high-speed motor 13 is fixedly provided on one side of the forming and processing box 4 through a flange, and an output end of the high-speed motor 13 movably passes through one side of the forming and processing box 4 .

[0030] In order to form the transmitted nylon material into particles, a cutting and forming device 2 for forming the transmitted nylon material into particles is provided at the output end of the high-speed motor 13, which is used to cut the nylon material extruded in the die head 12 and form it into round particles;

[0031] like Figure 4As shown, the cutting and forming device 2 includes a connecting ring 21, which is fixedly arranged at the output end of the high-speed motor 13. Four oblique cutting plates 22 are fixedly arranged on the outer surface of the connecting ring 21. The four oblique cutting plates 22 are respectively close to one side of the die head 12. A plurality of forming grooves 23 are opened on one side of the oblique cutting plate 22. The forming grooves 23 are arc-shaped and correspond to the through holes of the die head 12. The connecting ring 21 is driven by the high-speed motor 13, so that the plurality of oblique cutting plates 22 can be driven to rotate and cut. Since the oblique cutting plates 22 are close to one side of the die head 12, when the die head 12 extrude nylon material, it can be cut by the oblique cutting plates 22. The cut nylon material is rounded and granulated by the forming grooves 23 on the oblique cutting plates 22. Due to the high-speed cutting, the cut nylon material rolls in the forming grooves 23, so that round particles can be presented, thereby avoiding the problem of different particle shapes, thereby improving the efficiency of particle forming.

[0032] In order to cool the formed particles by air, an exhaust cooling device 3 for air cooling is provided inside the forming processing box 4, which is used to blow cold air to the formed particles to cool them down and avoid sticking between the particles.

The coolant is circulated and cooled, and then flows into the first liquid cooling tube 33 and the second liquid cooling tube 34. Since the two liquid cooling tubes are located on the inner side of the molding processing box 4, the drawn air is cooled. A plurality of fan blades 35 are fixedly provided on the outer surface of the output end of the high-speed motor 13. Therefore, when particle molding is performed, the fan blades 35 are driven to extract air. Since the fan blades 35 are located on one side of the two cooling tubes, the drawn air is cooled. The cooled air is blown toward the oblique cutting plate 22 and the die head 12 through the fan blades 35, so that the cut nylon material is cooled in time to avoid the problem of sticking between particles.

[0034] The working principle is as follows: the melted glass fiber reinforced nylon material is poured into the feed hopper 6, and the nylon material is conveyed by the rotating motor 5 to drive the transmission auger 11. A heating cylinder 10 is provided on the inner side of the transmission box 1 to prevent the nylon material from solidifying.
