Description

TECHNICAL FIELD

[0001] The utility model relates to injection molding processing technical field, concretely relates to a raw material stirring machine for injection molding production and processing. BACKGROUND

[0002] Injection molding is a process that melts plastic is injected into a mold cavity through a mold, and the desired shape of plastic product is obtained after cooling and solidification. The raw materials used in injection molding often include plastic particles of different colors, plastic particles of different materials, and various additives that may need to be added, such as plasticizers, flame retardants, colorants, etc. The uniformity of the mixing of these raw materials directly affects the color, mechanical properties and appearance quality of the injection molded parts. If the raw materials are not mixed uniformly, the injection molded parts may have uneven color, large performance difference, surface defects and other problems, thereby affecting the overall quality of the product and market competitiveness.

[0003] The injection material mixing and stirring device disclosed in the publication No. CN221985493U sets up a stirring motor, controls the stirring motor to drive the stirring rod to rotate by using a control panel, so that the first stirring assembly and the second stirring assembly can stir the injection material in the stirring box. The first stirring assembly is composed of three groups of paddles with gradually decreasing lengths, and the second stirring assembly is composed of a first arc-shaped rod, a second arc-shaped rod and a raking plate. The first arc-shaped rod and the second arc-shaped rod have a gap therebetween, and the raking plate has a sharp end at one end, which can improve the mixing and stirring effect of the injection slurry, has good mixing and stirring effect, and the top end of the stirring rod is provided with a deflector, which can make the injection material more dispersed and ensure the mixing and stirring effect by deflecting the injection material entering the crushing box from the discharge port.

[0004] Although the above-mentioned injection material mixing and stirring device has good performance in the crushing, mixing and stirring, and heating and melting of the injection material, it still has some deficiencies in the discharging process, i.e. it is not equipped with a filtering mechanism. Specifically, after the stirring is completed, the molten injection material is discharged from the discharge pipe by opening the valve for the use of the injection molding machine. However, in this process, the molten injection material may still contain some particles, impurities or bubbles that are not completely crushed or mixed uniformly. These undesirable factors may directly enter the injection molding machine, which may affect the quality of the injection molded parts, such as surface defects, uneven performance, etc.

[0005] Therefore, it is necessary to invent a raw material stirring machine for injection molding production and processing to solve the above-mentioned problems. UTILITY MODEL CONTENTS

[0033] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0034] This utility model provides, for example Figures 1-5 The raw material mixer shown includes a mixing tank 1. A discharge valve pipe 2 is fixedly connected to one side of the bottom of the mixing tank 1. The input end of the discharge valve pipe 2 is connected to the inside of the mixing tank 1. A filter assembly 3 is installed at the output end of the discharge valve pipe 2. The filter assembly 3 includes a filter sleeve 4 and a filter screen 5. The input end of the filter sleeve 4 is threadedly connected to the output end of the discharge valve pipe 2. The filter screen 5 is located at the output end of the filter sleeve 4. Multiple locking movable parts 6 are installed in a ring array on the outside of the filter sleeve 4. Multiple locking fixed parts 7 are installed in a ring array on the outside of the filter screen 5. The multiple locking movable parts 6 are respectively engaged with the multiple locking fixed parts 7.

[0035] In one aspect of this embodiment, a feeding box 8 is installed on the top of the mixing tank 1. A sealing cover 9 is hinged to the top of the feeding box 8. The bottom of the feeding box 8 is connected to the interior of the mixing tank 1. Two crushing rollers 10 are rotatably connected inside the feeding box 8. The two crushing rollers 10 are connected by gear meshing. A No. 1 motor 11 is installed on the outside of the feeding box 8. The output shaft of the No. 1 motor 11 is connected to one end of one of the crushing rollers 10. A stirring mechanism 12 is provided inside the mixing tank 1. The stirring mechanism 12 includes a rotating shaft 13, stirring blades 14, and... The scraper 15 is fixedly connected to the bottom of the rotating shaft 13. One end of the stirring blade 14 is fixedly connected to the rotating shaft 13, and the other end of the stirring blade 14 is fixedly connected to the scraper 15. The bottom of the rotating shaft 13 is rotatably connected to the bottom of the mixing tank 1. A second motor 16 is installed at the bottom of the mixing tank 1. The output shaft of the second motor 16 is connected to the bottom of the rotating shaft 13. A support leg 17 is fixedly connected to the bottom of the mixing tank 1. A jacket is opened in the inner wall of the mixing tank 1. An electric heating tube 18 is installed inside the jacket. The electric heating tube 18 is spirally coiled.

[0036] Working principle of this utility model:

[0037] Refer to the instruction manual appendix Figures 1-5When using this utility model, first, turn on the power supply and start the electric heating tube 18 in the inner wall jacket of the mixing tank 1. The electric heating tube 18 is spirally coiled, which can evenly preheat the inside of the mixing tank 1 to ensure that the raw materials added later can melt quickly at a suitable temperature.

[0038] Open the sealing cover 9 on the top of the feeding box 8, pour the raw material into the feeding box 8, close the sealing cover 9, start the first motor 11, the first motor 11 drives one of the crushing rollers 10 to rotate, and through gear meshing transmission, the other crushing roller 10 rotates synchronously to crush the raw material, ensuring that the raw material particles are small and uniform, which is beneficial to subsequent melting and stirring. The crushed raw material will fall into the mixing tank 1.

[0039] While the raw materials are being crushed, motor 16 is started. Motor 16 drives the rotating shaft 13 to rotate, which in turn drives the stirring blade 14 and the scraper 15 to rotate inside the mixing tank 1. The stirring blade 14 is responsible for mixing the raw materials evenly, while the scraper 15 ensures that the raw materials do not adhere to the inner wall of the mixing tank, thus improving the stirring efficiency. As heating and stirring continue, the raw materials gradually reach a molten state.

[0040] When feeding, the feeding valve pipe 2 is opened, and the molten raw material begins to flow out through the feeding valve pipe 2. During the outflow process, the raw material first enters the filter sleeve 4 of the filter assembly 3. After being filtered by the filter screen plate 5, the unmelted raw material particles will be intercepted in the filter sleeve 4, while the pure molten raw material continues to flow out.

[0041] After the molten raw material is completely discharged, close the feeding valve pipe 2, stop the No. 2 motor 16 and the electric heating tube 18, and then disassemble the filter assembly 3 for cleaning. Sequentially unfasten the multiple locking movable parts 6 and locking fixing parts 7 to separate the filter screen plate 5 from the filter sleeve 4, making it easier to clean the filter screen plate 5 more thoroughly.
