Description

Technical Field

[0001] This utility model relates to the field of blow molding technology, specifically to an automatic metering and mixing structure for desiccant masterbatch used in injection molding machines. Background Technology

[0002] Injection molding machines are among the most common pieces of equipment in modern plastics processing, widely used in the automotive, home appliance, electronics, and medical industries to produce various precision plastic parts. Drying the plastic raw materials is crucial during the injection molding process, especially for moisture-sensitive high-performance engineering plastics such as nylon and polycarbonate. Desiccant masterbatch (usually plastic granules containing a desiccant) is an effective drying method that can absorb moisture and maintain the dryness of the raw materials during injection molding, thereby ensuring the quality of the final plastic products.

[0003] However, traditional methods of using desiccant masterbatch often face problems such as inaccurate metering and uneven mixing, especially in high-precision injection molding production. These problems can lead to excessive or insufficient use of desiccant, thus affecting the quality of the products. Traditional manual or semi-automatic desiccant addition methods not only rely on manual operation but are also prone to human error, resulting in inconsistent drying effects from batch to batch.

[0004] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop an automatic metering and mixing structure for desiccant masterbatch used in injection molding machines. Utility Model Content

[0005] The purpose of this invention is to provide an automatic metering and mixing structure for desiccant masterbatch used in injection molding machines, in order to solve the problems mentioned in the background art.

[0007] A technical solution for an automatic metering and mixing structure of desiccant masterbatch for injection molding machines includes: a frame, a hopper on the frame, a pressure ring on the outer wall of the hopper, and a discharge hose at the bottom of the hopper;

[0008] The hopper is provided with a top cover, and a feeding cover plate is provided on the top cover; a motor frame is installed on the top cover, and a motor is installed on the motor frame. The output end of the motor is connected to a stirring shaft, which passes through the top cover and extends into the hopper. A stirring blade is installed at the lower end of the stirring shaft.

[0009] The frame is provided with connecting profiles at its corners, and the ends of the connecting profiles are provided with mounting bases. The mounting bases are provided with weighing modules, and the top of the weighing modules is connected to a bearing plate. The bearing plate abuts against the pressure ring.

[0010] An opening and closing frame is provided outside the discharge hose. Two sets of opening and closing cylinders are symmetrically arranged on the opening and closing frame. A sealing strip is connected to the output end of the opening and closing cylinder, and guide seats are provided at both ends of the sealing strip. The guide seats slide along the opening and closing frame.

[0011] As a preferred technical solution, the weighing module is a pressure sensor that monitors the weight changes of the support plate and hopper in real time.

[0012] As a preferred technical solution, the stirring blades are fitted with a clearance between them and the inner wall of the hopper.

[0013] As a preferred technical solution, the opening and closing cylinder is horizontally positioned to drive the sealing strip to press or loosen the discharge hose.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention relates to an automatic metering and mixing structure for desiccant masterbatch used in injection molding machines.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides an automatic metering and mixing structure for desiccant masterbatch in injection molding machines: it includes a frame 1, on which a hopper 21 is mounted. A pressure ring 211 is fixed to the outer wall of the hopper 21 to increase its stability and load-bearing capacity. A discharge hose 22 is connected to the bottom of the hopper 21 to discharge the mixed desiccant masterbatch.

[0023] A top cover 23 is provided at the top of the hopper 21, and a feeding cover plate 231 is provided on the top cover 23 to facilitate the addition of desiccant masterbatch into the hopper 21. A motor frame 24 is also fixed on the top cover 23, and a motor 25 is mounted on the motor frame 24. A stirring shaft 26 is connected to the output end of the motor 25, and the stirring shaft 26 extends into the hopper 21 through the top cover 23. A stirring blade 27 is installed at the lower end of the stirring shaft 26 for mixing the desiccant masterbatch in the hopper 21.

[0024] A connecting profile 31 is provided at the corner of the frame 1, and a mounting base 32 is fixed to the end of the connecting profile 31. A weighing module 33 is provided on the mounting base 32, and a bearing plate 34 is connected to the top of the weighing module 33. The bearing plate 34 abuts against the pressure ring 211 on the outer wall of the hopper 21, thereby realizing real-time monitoring of the weight of the hopper 21 and the desiccant masterbatch inside.

[0025] An opening / closing frame 4 is provided on the outside of the discharge hose 22. Two sets of opening / closing cylinders 41 are symmetrically arranged on the opening / closing frame 4, and a sealing strip 43 is connected to the output end of the opening / closing cylinder 41.

[0026] As a preferred embodiment of this utility model, the weighing module 33 adopts a pressure sensor, which can monitor the weight changes of the bearing plate 34 and the hopper 21 in real time, thereby achieving accurate measurement of the desiccant masterbatch, avoiding errors in manual measurement, and improving the accuracy of measurement.

[0027] In addition, the gap fit between the stirring blade 27 and the inner wall of the hopper 21 ensures that the stirring blade 27 will not generate excessive friction with the inner wall of the hopper 21 when rotating, which not only ensures the stirring effect but also extends the service life of the equipment.

[0028] The opening and closing cylinder 41 is set horizontally. When the opening and closing cylinder 41 is working, it can horizontally drive the sealing strip 43 to press or loosen the discharge tube 22, realizing the automated control of discharge, which is easy to operate and improves production efficiency.
