Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, specifically a follow-up adaptive plastic molding machine. Background Technology

[0002] The adaptive servo plastic molding machine is a type of plastic molding equipment with advanced technology and broad application prospects. It achieves more precise and stable molding results through adaptive control technology, bringing greater convenience and benefits to the plastic product manufacturing industry. The technical principle of the adaptive servo plastic molding machine is mainly based on a closed-loop control system. The closed-loop control system collects real-time data during the processing through sensors, analyzes and processes this data, and then adjusts the molding machine's operating parameters based on the processing results to ensure processing quality and efficiency.

[0003] According to the search, the patent application with patent number 201821867445.X discloses a plastic molding machine, including a fixed base and a material handling chamber. The material handling chamber is welded to one side of the top of the fixed base, and an injection molding chamber is welded to the other side of the top of the fixed base. A transfer chamber is welded between the injection molding chamber and the material handling chamber. A feeding hopper is welded to the middle of the top of the material handling chamber. A transfer chamber is welded to one side of the bottom of the inner cavity of the feeding hopper, and a protective box is welded to the other side of the bottom of the inner cavity of the feeding hopper.

[0004] Although the plastic molding machine can fully disperse the material through the stirring rod, enabling it to melt quickly when heated, and can preheat and melt the material by setting a preheating rod at the bottom of the feed hopper, the preheating rod of the plastic molding machine is in a fixed position, and the stirring rod cannot stir the material at the bottom of the preheating rod, which can easily lead to uneven heating of the material.

[0005] Therefore, we propose a follow-up adaptive plastic molding machine. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a follow-up adaptive plastic molding machine, which solves the problem that the preheating rod is fixed in position in existing devices, and the stirring rod cannot stir the material at the bottom of the preheating rod, which easily leads to uneven heating of the material.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a follow-up adaptive plastic molding machine, including a base, an injection molding chamber and a material handling chamber are respectively installed on the left and right sides of the top surface of the base, a transfer chamber is installed in the middle of the top surface of the base, the two ends of the transfer chamber are respectively connected to the injection molding chamber and the material handling chamber, a feeding box is provided above the material handling chamber, and a spiral electric heating wire is fixedly installed on the inner wall of the feeding box;

[0008] The bottom of the feeding box is fixedly connected to a discharge pipe that communicates with the inlet of the material processing chamber. The top surface of the material processing chamber is detachably installed with a cover by bolts. The feeding box is equipped with a conveying assembly. The discharge pipe is connected to the top of the feeding box through a return pipe. The return pipe is U-shaped.

[0009] The conveying assembly includes a motor, a rotating rod, and helical blades. The motor is fixedly installed in the middle of the top surface of the cover. The output end of the motor is fixedly connected to the rotating rod through the top surface of the cover. Helical blades are fixedly fitted on the outer surface of the rotating rod.

[0010] Preferably, the bottom of the feed box is bucket-shaped, and the outline of the spiral blade matches the outline of the inner wall of the feed box. The rotating rod and the spiral blade are driven to rotate by a motor, and the material inside the feed box is conveyed to the discharge pipe through the spiral blade.

[0011] Preferably, the side wall of the discharge pipe is fixedly connected to an outlet pipe that communicates with its interior and is arranged in a ring array. The top of the side wall of the feed box is fixedly connected to an inlet pipe that communicates with its interior. The number of inlet pipes and outlet pipes are the same and their positions correspond. The two ends of the return pipe are connected to the outlet pipe and the inlet pipe respectively through flanges. The melted material enters the discharge pipe. Then, under the action of the spiral blades continuously conveying raw materials into the discharge pipe, the raw materials in the discharge pipe will enter the interior of the return pipe through the outlet pipe, and then return to the interior of the feed box through the inlet pipe. This process is repeated to continuously heat the material and make the material heated evenly.

[0012] Preferably, a heating sleeve is fixedly fitted on the outer surface of the middle part of the reflux pipe. The heating sleeve and the electric heating wire are both connected to the power supply through wires. The heating sleeve can heat the material inside the reflux pipe, preventing the material from cooling and sticking to the inner wall of the reflux pipe.

[0013] Preferably, a solenoid valve is installed at the bottom end of the discharge pipe, and a feed hopper is fixedly installed on one side of the top surface of the cover. Sensors are installed in the feed box, material handling chamber, transmission chamber and injection molding chamber. The sensors, electric heating wires, heating sleeves, motors and solenoid valves are all connected to the closed-loop control system through wires. This control method is existing technology and is not shown in the figure, so it will not be described in detail here.

[0014] This utility model provides a follow-up adaptive plastic molding machine. It has the following beneficial effects:

[0015] 1. This follow-up adaptive plastic molding machine heats and melts the material inside the feed box using an electric heating wire. The motor, rotating rod, and spiral blades allow the melted material to be conveyed to the discharge pipe. The material in the discharge pipe then flows back into the feed box through the return pipe, allowing the material to circulate within the feed box and ensuring uniform heating. This solves the problem of uneven heating caused by the fixed position of the preheating rod and the inability of the stirring rod to stir the material at the bottom of the preheating rod in existing devices.

[0016] 2. This follow-up adaptive plastic molding machine can heat the material inside the return pipe through the heating sleeve, preventing the material from cooling and sticking to the inner wall of the return pipe. The return pipe can be disassembled by connecting the two ends of the return pipe to the discharge pipe and the feed pipe through flanges, so as to facilitate cleaning of the inside of the return pipe and to facilitate maintenance of the return pipe and the heating sleeve.

A discharge pipe 22, connected to the inlet of the material handling chamber 2, is fixedly connected to the bottom of the feeding box 21. A cover 25 is detachably installed on the top surface of the material handling chamber 2 by bolts. The feeding box 21 is equipped with a conveying assembly 5. The discharge pipe 22 is connected to the top of the feeding box 21 through a return pipe 6, which is U-shaped. The conveying assembly 5 includes a motor 51. The motor 51 is fixedly installed in the middle of the top surface of the cover 25. The output end of the motor 51 passes through the top surface of the cover 25 and is fixedly connected to the rotating rod 52. The outer surface of the rotating rod 52 is fixedly fitted with the spiral blade 53. The bottom of the feed box 21 is bucket-shaped. The outline of the spiral blade 53 matches the outline of the inner wall of the feed box 21. The material inside the feed box 21 is heated and melted by the electric heating wire. The setting of the motor 51, rotating rod 52 and spiral blade 53 can make the melted material conveyed to the discharge pipe 22. Then the material in the discharge pipe 22 flows back to the inside of the feed box 21 through the return pipe 6, which can make the material circulate inside the feed box 21, thereby making the material heat evenly.

[0024] Example 2: Figure 2-4 As shown: A discharge pipe 26, connected to the interior of the discharge pipe 22 and arranged in a ring array, is fixedly connected to the side wall of the discharge pipe 22. A feed pipe 27, connected to the interior of the feed box 21, is fixedly connected to the top of the side wall of the feed box 21. The number of feed pipes 27 and the position of the discharge pipes 26 are the same. The two ends of the return pipe 6 are connected to the discharge pipe 26 and the feed pipe 27 respectively through flanges.

The return pipe 6 can be disassembled by connecting the two ends of the return pipe 6 to the discharge pipe 26 and the feed pipe 27 through flanges, so as to facilitate cleaning of the inside of the return pipe 6 and to facilitate maintenance of the return pipe 6 and the heating sleeve 61.

[0025] The working principle and usage process of this utility model: In use, the raw material is added to the inside of the feeding box 21 through the feeding hopper 24. Then, the material is heated and melted by the electric heating wire on the inner wall of the feeding box 21. Then, the motor 51 is started to drive the rotating rod 52 and the spiral blade 53 to rotate. Then, the spiral blade 53 conveys the melted material inside the feeding box 21 to the discharge pipe 22. Then, the material in the discharge pipe 22 will be conveyed to the return pipe 6 through the discharge pipe 26 under the pressure of the subsequent material. Then, the material in the return pipe 6 will re-enter the inside of the feeding box 21 through the feeding pipe 27. The heating sleeve 61 can heat the material inside the return pipe 6, so that the material inside the feeding box 21 will continue to flow and be heated evenly. Then, the solenoid valve 23 is opened, and the melted material enters the inside of the material processing chamber 2 and enters the inside of the injection chamber 4 through the pipe inside the transfer chamber 3 for injection molding.
