Description

Technical Field

[0001] This utility model belongs to the field of electric melting technology, and in particular relates to a direct-drive electric melting device. Background Technology

[0002] An injection molding machine is an industrial production device used in the injection molding process to extrude molten plastic raw materials into a mold. The molten plastic in the injection barrel will gather towards the front end of the barrel, and the screw will slowly retract to make room for the molten plastic. However, as the amount of molten plastic increases, it will gradually create pressure that pushes the screw backward, accelerating the screw's retraction speed. If the screw is allowed to retract too quickly, it will affect the quality of the injection molded product.

[0003] In practical use, injection molding machines require a hydraulic motor melting device to push in plastic raw materials. However, existing hydraulic motor melting devices have a complex structure, causing many inconveniences in actual use. Furthermore, these devices typically use a hydraulic motor for transmission. The hydraulic motor is driven by a servo motor that pumps hydraulic oil, which flows along the hydraulic hose to the circuit board. The hydraulic control valve in the circuit board controls the direction and flow rate of the hydraulic oil. After being controlled by the hydraulic control valve, the oil then flows along the hydraulic hose into the hydraulic motor drive chamber to drive the hydraulic motor. This process results in significant energy loss, complex hydraulic pipelines and circuit board structures, cumbersome control, high cost of hydraulic control valves and power drive systems, low transmission efficiency after multi-stage control, susceptibility to oil leakage, and inability to achieve high torque speeds.

Detailed Implementation

[0022] The following drawings will disclose several embodiments of this utility model. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these physical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0023] Furthermore, in this utility model, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the utility model. They are merely used to distinguish components or operations described with the same technical terms and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0024] This embodiment provides a direct-drive electric melting device. The direct-drive electric melting device has a simple structure and is easy to operate. It is driven by a servo motor 12, which has higher transmission efficiency, does not leak oil, achieves a higher torque speed, and effectively reduces energy consumption loss.

[0025] Combination Figures 1 to 3 As shown, the direct-drive electric melting device of this embodiment includes a dispensing section 10 and a feeding cylinder 20. The dispensing section 10 can discharge the molten glue, while the feeding cylinder 20 can supply the molten glue.

[0026] In this embodiment, the direct-drive electric melting glue device also includes a frame 30, on which an adjustment component 40 is provided to install the glue dispensing section 10 and the feed cylinder 20.

[0027] Combination Figure 1 and Figure 2As shown, the dispensing section 10 in this embodiment includes a dispensing block 11, a servo motor 12, and a melting screw 13. The dispensing block 11 is provided with a dispensing channel 111, and the melting screw 13 is disposed in the dispensing channel 111. The servo motor 12 is located at the end of the melting screw 13 and drives the melting screw 13 to rotate, thus dispensing the molten glue along the length of the dispensing channel 111. The molten glue is fed into the dispensing channel 111 after being fed by the feed cylinder 20. The servo motor 12 drives the melting screw 13 to rotate, causing the molten glue to move within the dispensing channel 111 and be dispensed. In this embodiment, the servo motor 12 is used for driving, which results in higher transmission efficiency, no oil leakage, and a higher torque speed, effectively reducing energy loss.

[0028] In this embodiment, the adjustment component 40 includes a drive cylinder 41, a first mounting base 42, and a second mounting base 43. The dispensing block 11 and the feed cylinder 20 are both mounted on the first mounting base 42, and the servo motor 12 is mounted on the second mounting base 43. A guide rail 50 is provided on the frame 30. The first mounting base 42 and the second mounting base 43 move along the length of the guide rail 50. Under the driving action of the drive cylinder 41, the first mounting base 42 and the second mounting base 43 move, thereby changing the position of the dispensing part 10 and the feed cylinder 20 to adapt to external injection molding machines and improve the versatility of the device.

[0029] Specifically, in this embodiment, the dispensing block 11 penetrates the first mounting base 42, and the dispensing block 11 is provided with an inlet hole 112. The first mounting base 42 is provided with a discharge channel. The outlet of the feeding cylinder 20 enters the inlet hole 112 through the discharge channel. The first mounting base 42 is fixedly connected to the second mounting base 43. The driving cylinder 41 drives the first mounting base 42. When the feeding cylinder 20 feeds the molten glue, the molten glue enters the inlet hole 112 of the dispensing block 11 through the discharge channel, and then enters the dispensing channel 111 so that the molten glue can be discharged.

[0030] In this embodiment, the feed cylinder 20 guides the molten adhesive into the dispensing channel 111. The outlet of the feed cylinder 20 corresponds to the beginning of the molten adhesive screw 13. The feed cylinder 20 is a conical cavity structure.

[0031] In practical use, the direct-drive electric melting device of this embodiment is installed on a fixed end. The dispensing part 10 discharges the molten glue, and the feeding cylinder 20 supplies the molten glue. The adjusting component 40 can install the dispensing part 10 and the feeding cylinder 20, and move the dispensing part 10 and the feeding cylinder 20 to improve the versatility of the device.

[0032] In summary, the direct-drive electric melting device of this embodiment has a relatively simple structure and is easy to operate. It is driven by a servo motor 12, which has higher transmission efficiency, no oil leakage, and can achieve a higher torque speed, effectively reducing energy loss. The presence of the adjustment component 40 allows for adjustment of the positions of the dispensing block 11, the servo motor 12, and the feed cylinder 20 to adapt to external injection molding machines and improve versatility.
