[0024] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.
[0025] Example 1: An automated waste plastic recycling and continuous processing device, such as Figures 1-5 As shown, it includes a hot melt box 1; it also includes a mounting base 3, a partition plate 4, a connecting plate 5 and an electric rotating plate 6; a mounting base 3 is provided in the hot melt box 1, and the mounting base 3 is connected to the partition plate 4, and the partition plate 4 is located in the middle of the hot melt box 1 in an upright state, and the partition plate 4 has a built-in heating module; a connecting plate 5 is respectively installed at both ends of the partition plate 4; an electric rotating plate 6 is respectively installed on the two connecting plates 5; the electric rotating plate 6 consists of a rotating plate and a motor that drives the rotating plate to rotate.
[0026] A rotary drive member 7 is mounted on the mounting seat 3 , and the rotary drive member 7 is a motor. The mounting seat 3 is rotationally connected to the partition plate 4 , and a driving end of the rotary drive member 7 is connected to the partition plate 4 .
[0027] A screen 8 is provided at the inlet of the hot melt box 1 , and the screen 8 covers half of the inlet of the hot melt box 1 .
[0028] The screen 8 is arranged to be inclined, and the side of the screen 8 with a lower height is located in the middle of the hot melt box 1.
[0029] The frame of the lower side of the screen 8 can cover the mounting base 3, the partition plate 4, the connecting plate 5, the electric rotating plate 6 and the rotating drive member 7 to prevent plastic from falling on the upper surfaces of these parts.
[0030] A row of heating tubes 9 distributed equidistantly is provided at the bottom of the hot melt box 1 .
[0031] In this embodiment, a plastic crusher can be installed on the upper part of the hot melt box 1 to allow the crushed plastic to fall directly into the hot melt box 1, or it can be directly covered (not shown in the figure). By putting the crushed plastic into the hot melt box 1 for hot melting treatment, the plastic is turned into liquid and then discharged from the discharge port of the hot melt box 1 (not shown in the figure). This is the existing technology and will not be repeated here.
[0032] Since the broken plastics are put into the hot melting box 1 for hot melting treatment, the heating treatment in the prior art is generally to set a heating source on the side wall or bottom wall of the hot melting box 1 for heating, but this will cause the plastics at the inner position of the plastics pile to be unable to be effectively conducted with heat, and the hot melting efficiency is low; therefore, the separating plate 4 is additionally arranged in the present application, and the separating plate 4 is located at the middle bottom position of the hot melting box 1, when the plastics are put into the hot melting box 1, the separating plate 4 is located at the middle position of the plastics pile, so as to improve the heating effect of the plastics at the inner position, and the heating pipes 9 at the bottom of the hot melting box 1 are responsible for overall heating, and the electric rotating plates 6 are arranged on both sides of the separating plate 4, and the hot melted plastics are stirred by the rotating movement of the electric rotating plates 6, so as to accelerate the hot melting.
[0033] Since the broken plastics still have sizes, that is, large plastics and small plastics, if the hot melting is directly carried out in the hot melting box 1, the small plastics will be quickly melted, and the large plastics will be relatively slowly melted, at this time, the hot melting temperature of each area of the hot melting box 1 still maintains a consistent high temperature state, but the small plastics which have been melted do not need high temperature hot melting, so the small plastics will consume excessive heating energy, and the energy consumption of the whole hot melting process is high; therefore, the sieve screen 8 is additionally arranged in the present application, and before the plastics are fed, the rotating driving member 7 is controlled to rotate the separating plate 4, the connecting plate 5 and the electric rotating plate 6 as a whole to the side edge of the electric rotating plate 6 to be in contact with the inner wall of the hot melting box 1, at this time, as shown in Figure 2 the separating plate 4 and the electric rotating plate 6 divide the hot melting box 1 into two spaces on the left and right, then the falling position of the plastics put in is aligned with the sieve screen 8, the small plastics smaller than the aperture of the sieve screen 8 pass through the sieve screen 8 and enter one of the spaces, that is, the left space, and the large plastics larger than the aperture of the sieve screen 8 slide along the upper surface of the inclined sieve screen 8 and enter the other space, that is, the right space, so as to realize that the left space separated by the separating plate 4 and the electric rotating plate 6 is used for stacking the small plastics, and the right space separated by the separating plate 4 and the electric rotating plate 6 is used for stacking the large plastics, so that the plastics of different sizes are placed in different areas, the heating pipes 9 at the bottom of the right space for stacking the large plastics can be kept in a high temperature state to melt the large plastics, and the heating pipes 9 at the bottom of the left space for stacking the small plastics can be appropriately cooled after the small plastics are completely melted, so as to realize the effect of reducing energy consumption.
[0034] In the embodiment 1, the electric drive moving mechanism 2 is arranged in the hot melting box 1, and the mounting seat 3 is installed on the moving end of the electric drive moving mechanism 2. Figures 1-5
[0035] The electric drive moving mechanism 2 is composed of a lead screw, a motor for driving the lead screw and a light rod for auxiliary limiting, the lead screw is driven to rotate by the motor to drive the mounting seat 3 to move.
[0036] When it is necessary to push the unmelted plastic in the hot melt plastic liquid, the electric rotating plate 6 is controlled to rotate so that a gap of fixed width is formed between the electric rotating plate 6 and the partition plate 4 and the inner wall of the hot melt box 1.
[0037] The upper portion of the hot melt box 1 is provided with a suction pipe connected to an external suction pump, through which harmful fumes generated during the hot melting of plastics are sucked away.
[0038] In this embodiment, taking into account the difference in the number of large pieces of plastic and small pieces of plastic, an electric drive moving mechanism 2 is additionally provided. The electric drive moving mechanism 2 controls the movement of the mounting base 3 to adjust the positions of the partition plate 4 and the electric rotating plate 6, thereby adjusting the size of the two spaces separated by the partition plate 4 and the electric rotating plate 6. For example, if there are more large pieces of plastic, the partition plate 4 and the electric rotating plate 6 are controlled to move to the left as a whole, so that the right space for stacking large pieces of plastic is larger, while the left space for stacking small pieces of plastic is reduced, so as to adapt the ratio of the number of large pieces of plastic to small pieces of plastic.
[0039] Furthermore, considering that when melting a large piece of plastic, some larger and harder plastics melt slowly, in order to reduce the energy consumption of hot melting the entire large piece of plastic, after the hot melting is carried out for a period of time, the electric rotating plate 6 is controlled to rotate, such as Figure 5 As shown, a gap of fixed width is formed between the electric rotating plate 6 and the partition plate 4 and the inner wall of the hot melt box 1, and then the electric drive moving mechanism 2 is controlled to drive the mounting seat 3 to move, so that the electric rotating plate 6 and the partition plate 4 move toward the right side of the space where the large piece of plastic is stacked. During the movement, the melted plastic liquid is allowed to pass through the gap formed between the electric rotating plate 6 and the partition plate 4 and the inner wall of the hot melt box 1, while the larger and harder plastic that is not completely melted cannot pass through the gap, so that this part of the larger and harder plastic that is not completely melted is pushed by the moving electric rotating plate 6 and the partition plate 4, thereby realizing the concentration of the larger and harder plastic that is not completely melted, and cooperating with the heating tube 9 in the high temperature state at this position, the concentrated plastic is subjected to targeted heating treatment to improve the efficiency of hot melting.
[0040] In the final stage of hot melting, the plastic has been basically hot melted, and the partition plate 4, the connecting plate 5 and the electric rotating plate 6 are rotated as a whole by manipulating the rotary drive member 7. Figure 4 As shown, the electric rotating plate 6 is controlled to rotate at the same time, which can stir the hot melt plastic in a large range to ensure that all the plastic is hot-melted.

Any equivalent substitutions made within the principles of the present invention are intended to be included within the scope of protection of the present invention. Any content not elaborated in detail herein is already known to those skilled in the art.
