Abstract
Description

[0021] Combined with appendix Figure 1-4 This embodiment proposes a sealed plastic mixing line, comprising a production module consisting of a mixer 1, an elevator 2, and an extruder 3 arranged sequentially. It also includes a surrounding component 4 enclosing the production module on its perimeter and top. A doorway 5 is provided on the surrounding component 4 near the connection between the mixer 1 and the elevator 2. A dust collector is also included, with its suction inlet 6 passing through the top surrounding component 4. At least one dust collector suction inlet 6 is located above the feeding area of the elevator 2, and at least one dust collector suction inlet 6 is located above the unloading area of the elevator 2. A control unit is also included, electrically connected to the mixer 1, elevator 2, extruder 3, and dust collector.
[0022] The basic working process of the sealed plastic mixing line in this embodiment is as follows: after the plastic and filler materials are mixed in the mixing mill 1, the mixing hopper of the mixing mill 1 is flipped and reversed to pour the mixed material into the lifting hopper of the elevator 2. The mixed material clump enters the extruder 3 through the lifting hopper for pelletizing. During the process of the mixed material being poured from the mixing hopper into the lifting hopper, some incompletely mixed dust will enter the air, causing dust to disperse in the air. In this embodiment, the production module consisting of the mixing mill 1, elevator 2 and extruder 3 is enclosed by the enclosure 4, which can effectively prevent dust, odors and other contaminants from spreading throughout the workshop.
[0023] The surrounding component 4 is generally a soft curtain. In a preferred embodiment, a fixed frame 12 is provided around the production module consisting of a mixer 1, an elevator 2 and an extruder 3 arranged in sequence. The soft curtain is laid on the fixed frame 12 to enclose the production module.
[0024] Furthermore, this embodiment also includes a dust collector. The suction port 6 of the dust collector passes through the enclosure 4 and can collect dust within the enclosed space formed by the enclosure 4. As can be seen from the foregoing description, dust is generally generated during the feeding stage of the elevator 2 (i.e., the stage from the mixing hopper to the elevator hopper) and the unloading stage (i.e., the stage from the elevator hopper to the extruder 3 hopper). Therefore, the suction port 6 of the dust collector needs to be preferentially set above the feeding area and the unloading area of the elevator 2. This setting can fully collect the dust that is not completely mixed in the mixture and prevent dust from entering the working environment.
[0025] Through the configuration of the control unit, the dust collector, internal mixer 1, elevator 2, and extruder 3 in this embodiment achieve automated operation. The automated operation process is as follows: When the internal mixer 1 completes the mixing process, a signal is transmitted to the control unit. The control unit then sends a signal to start the dust collector, and the dust collector's fan starts running to collect dust. When the mixing hopper of the internal mixer 1 completes the material turning action and returns to the mixing station, a signal is transmitted to the control unit. The control unit then starts the elevator 2, and the elevator hopper of the elevator 2 begins to lift. When the elevator hopper of the elevator 2 completes the material turning action and returns to the lifting station, a signal is transmitted to the control unit. The control unit then sends a signal to start the dust collector, and the dust collector's fan stops running.
[0026] To further collect dust, a suction hood 11 is provided at the end of the air intake 6. The suction hood 11 has an flared structure, which can increase the suction area and thus better achieve the dust collection effect.
[0027] In this embodiment, by setting up a safety door 5, the connection between the enclosed space and the outside world is ensured. When the processing line is working normally, the safety door 5 is normally closed to prevent personnel from entering the production line while the equipment is running, effectively preventing workplace accidents such as crush injuries.
[0028] In a further embodiment, a track 7 is provided at the doorway, and the safety door 5 slides in conjunction with the track 7 to close or open the doorway. The track 7 can be an electric slide rail and is electrically connected to the control unit. When the processing line starts working, the control unit can control the electric slide rail to move the safety door 5 to close the doorway and ensure the airtightness of the enclosed space.
[0029] Furthermore, the security door 5 is equipped with a lock cylinder 8, and the door opening is equipped with a latch 9. The lock cylinder 8 is used to lock with the latch 9. When the lock cylinder 8 is connected to the latch 9, the security door 5 cannot be opened.
[0030] The lock head 8 is preferably an electronic lock, which is electrically connected to the control unit to automatically control the locking of the lock head 8 and the latch 9. For example, when the hoist 2 starts working, the control unit sends a signal to the lock head 8 to lock the safety door 5; when the hoist bucket of the hoist 2 returns to the working position, a signal is transmitted to the lock head 8, and the lock head 8 and the latch 9 unlock, so the safety door 5 can be opened.
[0031] In summary, to address the technical problems of existing internal mixing production lines, this embodiment constructs an enclosed space around the production module using the surrounding component 4 to prevent dust from drifting into the external environment; and uses a dust collector to collect the dust in the enclosed space, thereby further improving the working environment; and the physical isolation of the production line from the external environment can effectively prevent personnel from entering the production line while the equipment is running, effectively preventing workplace accidents such as crush injuries.
[0032] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited to this. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
