Description

Technical Field

[0001] This utility model relates to the field of modified engineering plastics feeding technology, specifically to a feeding machine for processing modified engineering plastics. Background Technology

[0002] Modified engineering plastics, as a high-performance plastic material, possess excellent mechanical properties, heat resistance, and corrosion resistance, meeting the specific material requirements of various industries, thus leading to a continuous increase in demand. In the processing of modified engineering plastics, the feeding stage is a crucial step, directly impacting processing efficiency and quality.

[0003] When modified engineering plastics are fed, the plastic formulation typically contains various functional additives (including plasticizers, inorganic fillers, etc.). These components are prone to electrostatic adsorption and viscous agglomeration after material mixing. Especially under temperature and humidity changes or prolonged static conditions, the material tends to clump and adhere tightly to the inner wall of the conveying pipe, the gaps between the screw conveyor blades, and the joints at the discharge port. Traditional mechanical dispersing devices and vibration schemes can only achieve surface loosening and have limited effectiveness in handling materials that have already formed molecular-level adhesion. This leads to frequent abnormal operating conditions such as gradual material accumulation on the pipe walls and material wrapping around the screw blades during equipment operation. This not only causes material blockage due to the reduction of the effective diameter of the conveying pipe, but also significantly reduces the conveying efficiency per unit time. At the same time, it causes abnormal fluctuations in the torque of the screw shaft, leading to overload and burnout of the drive motor, seriously affecting production continuity and significantly increasing maintenance costs. Utility Model Content

[0004] The purpose of this utility model is to provide a feeding machine for modified engineering plastics processing, which solves the following technical problems: When feeding modified engineering plastics, the plastic formulation usually contains a variety of functional additives (including plasticizers, inorganic fillers, etc.). These components are prone to electrostatic adsorption effect and viscous agglomeration after the materials are mixed. Especially when the temperature and humidity change or when the material is left to stand for a long time, the material is prone to clump together and adhere tightly to the inner wall of the conveying pipe, the gap between the screw conveyor blades and the joint of the discharge port.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A feeding machine for processing modified engineering plastics includes a tank body with a discharge port at one end. A conveying unit is provided at one end of the discharge port. The conveying unit includes a conveying pipe connected to the discharge port. A drive assembly is fixedly installed at the upper end of the conveying pipe. A shaft is fixedly provided at the output end of the drive assembly. A spiral blade extending into the discharge port is fixedly provided on the outer surface of the shaft. Multiple slots are symmetrically opened on the outer surface of the conveying pipe. A conveying shell is rotatably connected to one side of each slot via a hinge. A fixing assembly is provided at the upper end of the conveying pipe for engaging and fixing the conveying shell.

[0007] As a further embodiment of this utility model: the fixing component includes a rectangular block fixedly disposed at the upper end of the conveying pipe, the rectangular block having a groove inside, a sliding rod slidably disposed inside the groove, and a limit block fixedly disposed at one end of the sliding rod.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1As shown, this utility model is a feeding machine for processing modified engineering plastics, including a tank body 1. One end of the tank body 1 has a discharge port 11, and one end of the discharge port 11 is equipped with a conveying unit 2. The conveying unit 2 includes a conveying pipe 21 connected to the discharge port 11. A drive assembly 22 is fixedly installed at the upper end of the conveying pipe 21. The drive assembly 22 can be a servo motor. A shaft 23 extending to the bottom of the conveying pipe 21 is fixedly installed at the output end of the drive assembly 22. The extension direction of the shaft 23 is consistent with the direction of the conveying pipe 21. An extension extending to the bottom of the conveying pipe 21 is fixedly installed on the outer surface of the shaft 23. The spiral blade 24 is located inside the discharge port 11. Multiple slots 211 are symmetrically opened on the outer surface of the conveying pipe 21. One side of each slot 211 is rotatably connected to a conveying shell 3 via a hinge. The conveying shell 3 matches the slot 211. A fixing component 4 is provided at the upper end of the conveying shell 3 and the conveying pipe 21. The fixing component 4 is used to lock and fix the conveying shell 3. Releasing the restriction of the fixing component 4 and opening the conveying shell 3 allows for periodic cleaning of the spiral blade 24 inside the conveying pipe 21. At the same time, when the conveying pipe 21 is blocked, opening the conveying shell 3 can clean the blockage inside the conveying pipe 21 and improve the feeding rate.

[0026] In summary, a modified engineering plastics processing feeder, during feeding, drives the shaft 23 to rotate via the drive component 22, thereby slowly conveying the modified engineering plastics inside the tank 1 along the spiral blade 24 to the upper end of the conveying pipe 21, and then conveying them from the upper end of the conveying pipe 21 into the next processing equipment.

[0027] Example 2: Based on Example 1, please refer to... Figure 2-5 As shown, the fixing component 4 includes a rectangular block 41 fixedly mounted on the upper end of the feed pipe 21. A groove 42 is formed inside the rectangular block 41. A sliding rod 43 is slidably mounted inside the groove 42. A limit block 44 is fixedly mounted on one end of the sliding rod 43, and a pull rod 45 is fixedly mounted on the other end of the sliding rod 43. A first spring 46 is sleeved on the sliding rod 43. One end of the first spring 46 is fixedly connected to the limit block 44, and the other end of the first spring 46 is fixedly connected to the groove 42. The pull rod 45 drives the sliding rod 43 to slide back and forth in the groove 42, compressing the first spring 46 and moving the limit block 44 into the groove 42.

[0028] The upper end of the material conveying shell 3 is symmetrically provided with fixing blocks 47. The upper end of the fixing block 47 is provided with a limiting groove 48 that matches the limiting block 44. The material conveying shell 3 is fixed by matching the limiting block 44 with the limiting groove 48.

[0029] A snap-fit ​​assembly 5 is provided on the lower side of one side of the material conveying shell 3. The snap-fit ​​assembly 5 includes a connecting block 51 fixedly installed on the side wall of the material conveying pipe 21. Side plates 52 are symmetrically arranged on the upper end of the connecting block 51. A connecting rod 53 is rotatably arranged between the two side plates 52. A rotating block 54 is fixedly installed on the upper end of the connecting rod 53. The connecting rod 53 drives the rotating block 54 to rotate.

[0030] The rotating block 54 has a through hole 541 extending to its top. A slider 542 is movably disposed inside the through hole 541. A second spring 543 is fixedly disposed between the slider 542 and the through hole 541. A lever 544 is disposed at the upper end of the slider 542 extending to the upper end of the rotating block 54. The lever 544 can reciprocate on the through hole 541. A retaining ring 545 matching the slider 542 is fixedly disposed on one side of the material conveying shell 3.

[0031] A drive motor 6 is fixedly installed on one side of the tank body 1. The output end of the drive motor 6 extends into the tank body 1 and a rotating shaft 7 is fixedly installed thereon. Stirring blades 8 are symmetrically arranged on the outer surface of the rotating shaft 7.

[0032] The upper end of the tank body 1 is provided with a feed inlet 12, and the upper end of the conveying pipe 21 is provided with a discharge outlet 212.

[0033] In summary, during operation, insufficient drying of the plastic can lead to clumping or uneven particle size, resulting in excessive modified plastic particles adhering to the conveying pipe 21 and the spiral blade 24, and even causing blockage of the conveying pipe 21. After a batch of modified engineering plastics has been fed, the movable lever 544 can be used to move the slider 542 backward, removing the slider 542 from the retaining ring 545. Then, the pull rod 45 can be pulled to cause the limiting block 44 to squeeze the first spring 46, releasing the limiting block 44 from the limiting groove 48. This allows the conveying shell 3 to be opened to clean the modified plastic particles adhering to the inner wall of the conveying pipe 21 and the spiral blade 24. In case of blockage, the conveying shell 3 can also be opened to clean the blocked part, preventing damage to the equipment caused by the blockage.

[0034] Example 3

[0035] This embodiment is obtained by combining Embodiment 1 and Embodiment 2.

[0036] By pre-crushing and dispersing the modified engineering plastics and quickly fixing and opening the conveying shell 3, not only can large particle agglomerates be prevented from entering the conveying pipe 21, but the modified plastics adhering to the inner wall of the conveying pipe 21 and the surface of the spiral blade 24 can also be cleaned regularly, effectively preventing blockage, improving the feeding rate, and ensuring the continuity of production.
