Description

Technical Field

[0001] This utility model belongs to the technical field of functional plastic masterbatch processing equipment, and particularly relates to a functional plastic masterbatch granulator. Background Technology

[0002] Functional plastic masterbatch is a granular product made from a specific color pigment (or dye) as a base, compounded with carrier resin, dispersant, stabilizer, and additional functional additives with special properties (such as antioxidants, UV stabilizers, antibacterial agents, antistatic agents, flame retardants, thermal conductive agents, etc.). After scientific formulation, mixing and modification, it is compounded and granulated by an extruder. Its particle shape is similar to that of ordinary plastic granules. When used, it can be directly mixed with plastic substrates in proportion. It can efficiently and uniformly impart the target color to plastic products, solving the problems of uneven dispersion and dust generation of traditional pigments. At the same time, it can simultaneously impart single or combined functions such as anti-aging, UV resistance, antibacterial, antistatic, flame retardant, and thermal conductivity to products. It also has the advantages of convenient measurement, environmental friendliness, and stable performance. It is widely used in electronics, automotive interiors, packaging materials, daily necessities, medical plastics and other fields to meet the dual needs of plastic products for color and specific functions in different scenarios. Functional plastic masterbatches need to be processed into granules by a granulator. Its core system includes an extrusion system (screw, barrel), a heating and cooling system, a transmission system, and a pelletizing system. The process parameters can be adjusted according to the characteristics of the raw materials (such as PE, PP, PVC, rubber, etc.) and the specifications of the finished granules (such as cylindrical or spherical). It features high automation, stable granulation efficiency, and uniform quality of finished granules. It is widely used in plastic production, plastic recycling, preparation of functional masterbatches (such as flame retardant masterbatches and color masterbatches), rubber processing and other fields. It is a key piece of equipment connecting raw material processing and downstream product molding.

[0003] Because conventional granulators lack a sensing mechanism in their feeding hopper, the granulator is prone to running empty when operators are negligent, causing unnecessary waste and even mechanical overheating failure, resulting in the relatively low practicality of conventional granulators.

[0004] To address these issues, we propose a functional plastic masterbatch granulator. Utility Model Content

[0005] The purpose of this invention is to solve the problem of low practicality of conventional granulators, and to propose a functional plastic masterbatch granulator.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A functional plastic masterbatch granulator includes a granulator body. A feeding hopper is fixedly connected to the feeding port of the granulator body. A limit frame is fixedly connected to the upper part of the feeding hopper. A micro switch is fixedly connected to the upper end of the limit frame. A rotating shaft is rotatably mounted on the lower part of the feeding hopper. A weight is fixedly connected to the side end of the rotating shaft. A movable cover is fixedly connected to the rotating shaft. The movable cover is located outside the feeding hopper. The micro switch is in contact with the movable cover. After the raw material is poured into the space between the hopper and the movable cover, the material pushes against the movable cover, causing it to open outwards. A limit bracket then restricts the movable cover to prevent it from opening excessively and leaking material. This causes the movable cover to disengage from the micro switch. When only a small amount of material remains at the bottom of the hopper, the inner side of the movable cover loses its expansion effect. The weight of the block then acts on the rotating shaft, causing it to rotate and reset the movable cover. Pressing the micro switch with the movable cover sends an empty material electrical signal, allowing intelligent equipment to identify the empty material or for alarm equipment to automatically trigger an empty material alarm.

[0007] Preferably, the feeding hopper includes a hopper body, a shaft seat is fixedly connected to the lower side of the hopper body, the lower end of the hopper body is fixedly connected to the feeding port of the granulator body, and the limiting frame is fixedly connected to the upper part of the hopper body. The hopper body guides the raw material into the feeding port of the granulator body.

[0008] Preferably, the rotating shaft includes a connecting seat, which is in movable contact with the bucket body. A shaft is fixedly connected to the side end of the connecting seat, and the shaft is rotatably mounted inside the shaft seat. The weight is fixedly connected to the outer end of the shaft. The weight acts on the shaft, which in turn acts on the connecting seat, which in turn acts on the movable cover, causing the movable cover to automatically return to its original position after being emptied, facilitating this process.

[0009] Preferably, the movable cover includes a baffle, and a fan-shaped baffle is fixedly connected to the side of the baffle. The baffle and the fan-shaped baffle are in movable contact with the hopper body, and the lower end of the baffle is fixedly connected to the upper end of the connecting seat. The material acts outward on the baffle, causing it to open outward. The fan-shaped baffle blocks the gap between the hopper body and the baffle, preventing material leakage.

[0010] Preferably, the movable cover further includes a pressure plate, which is fixedly connected to the side end of the sector-shaped baffle. The pressure plate increases the contact range between the movable cover and the micro switch.

[0011] Preferably, the micro switch includes a fixed base, and a switch body is fixedly connected to the upper part of the fixed base. The switch body is fixedly connected to the upper part of the fixed base, and the pressure plate is in contact with the switch body. The switch body senses whether the movable cover has returned to its original position.

[0012] In summary, the technical effects and advantages of this utility model are as follows: 1. After the raw material is poured into the space between the hopper and the movable cover, the material pushes the movable cover outward. The limit frame limits the movable cover to prevent it from opening too wide and leaking material. The movable cover then disengages from the micro switch. When only a small amount of material remains at the bottom of the hopper, the inner side of the movable cover loses its expansion effect. The weight of the block acts on the rotating shaft, causing it to rotate and reset the movable cover. Pressing the micro switch through the movable cover sends an empty material electrical signal, which allows intelligent equipment to identify the empty material or provides an automatic empty material alarm for the alarm equipment.

[0013] 2. The weight of the block acts on the shaft, which in turn acts on the connecting seat, which in turn acts on the movable cover, so that the movable cover automatically returns to its original position after the material is emptied, making it convenient to return to its original position after the material is emptied.

A limit frame 6 is fixedly connected to the upper part of the feeding hopper 2. A micro switch 5 is fixedly connected to the upper end of the limit frame 6. A rotating shaft 3 is rotatably installed on the lower part of the feeding hopper 2. A weight 7 is fixedly connected to the side end of the rotating shaft 3. A movable cover 4 is fixedly connected to the rotating shaft 3. The movable cover 4 is movable outside the feeding hopper 2. The micro switch 5 is in contact with the movable cover 4. After the raw material is poured into the space between the feeding hopper 2 and the movable cover 4, the material pushes the movable cover 4 outward. The limit frame 6 limits the movable cover 4 to prevent it from opening too wide and leaking material. The movable cover 4 is then disengaged from the micro switch 5. When only a small amount of material remains at the bottom of the feeding hopper 2, the inner side of the movable cover 4 loses its expansion effect. The weight of the weight block 7 acts on the rotating shaft 3, causing the rotating shaft 3 to rotate and drive the movable cover 4 to reset. The movable cover 4 presses the micro switch 5, which then sends an empty material electrical signal.

[0018] like Figure 1 and 2 As shown, the feeding hopper 2 includes a hopper body 21, with a shaft seat 22 fixedly connected to the lower side of the hopper body 21. The lower end of the hopper body 21 is fixedly connected to the feeding port of the granulator body 1, and a limiting frame 6 is fixedly connected to the upper part of the hopper body 21. The hopper body 21 guides the raw materials into the feeding port of the granulator body 1.

[0019] like Figure 1 , 2 As shown in Figure 3, the rotating shaft 3 includes a connecting seat 31, which is in movable contact with the bucket body 21. A shaft body 32 is fixedly connected to the side end of the connecting seat 31. The shaft body 32 is rotatably installed inside the shaft seat 22, and a weight 7 is fixedly connected to the outer end of the shaft body 32. The weight 7 acts on the shaft body 32, which in turn acts on the connecting seat 31, and then on the movable cover 4, causing the movable cover 4 to automatically return to its original position after the material is emptied.

[0020] like Figure 1 , 2 As shown in Figures 3 and 4, the movable cover 4 includes a baffle 41, and a fan-shaped baffle 43 is fixedly connected to the side of the baffle 41. The baffle 41 and the fan-shaped baffle 43 are in movable contact with the hopper body 21, and the lower end of the baffle 41 is fixedly connected to the upper end of the connecting seat 31. The material acts outward on the baffle 41, causing the baffle 41 to open outward. The fan-shaped baffle 43 blocks the gap between the hopper body 21 and the baffle 41, preventing material leakage.

[0021] like Figure 1 and 4 As shown, the movable cover 4 also includes a pressure plate 42, which is fixedly connected to the side end of the sector-shaped baffle 43. The pressure plate 42 increases the contact range between the movable cover 4 and the micro switch 5.

[0022] like Figure 1 , 4 As shown in Figure 5, the micro switch 5 includes a fixed base 51, and a switch body 52 is fixedly connected to the upper part of the fixed base 51. The switch body 52 is fixedly connected to the upper part of the fixed base 51, and the pressure plate 42 is in contact with the switch body 52. ​​The switch body 52 is used to sense whether the movable cover 4 has returned to its original position.

[0023] Working principle: After the raw material is poured into the space between the feeding hopper 2 and the movable cover 4, the moving cover 4 is pushed outward by the raw material. The limit frame 6 limits the movable cover 4 to prevent it from opening too wide and leaking material. The movable cover 4 is then disengaged from the micro switch 5. When only a small amount of material remains at the bottom of the feeding hopper 2, the inner side of the movable cover 4 loses its expansion effect. The weight of the weight block 7 acts on the rotating shaft 3, causing the rotating shaft 3 to rotate and drive the movable cover 4 to reset. The movable cover 4 presses the micro switch 5, which sends an empty material electrical signal.
