Description

Technical Field

[0001] This utility model relates to the field of plastic melting technology, specifically to a plastic melting device for the production of biodegradable plastic tableware. Background Technology

[0002] Biodegradable plastics refer to a class of plastics whose properties remain unchanged during their shelf life, but which can degrade into environmentally harmless substances under natural environmental conditions after use. Based on the degradation principle, they can be divided into photodegradable plastics, biodegradable plastics, and water-degradable plastics.

[0003] CN217454533U discloses a polymer plastic masterbatch melting device, relating to the field of melting technology. It includes a melting shell, a preheating shell fixedly connected to its top, a water pipe fixedly connected to the inner wall of the preheating shell, a T-shaped extrusion rod slidably connected through the left wall of the preheating shell, a fixing assembly on the left side of the preheating shell, and an extrusion plate fixedly connected to the right side of the T-shaped extrusion rod. This application mainly involves placing plastic masterbatch into the preheating shell through an inlet, preheating the masterbatch with hot water from the water pipe, and then pushing the T-shaped extrusion rod to force the extrusion plate through the pipe into the melting shell. The melting process is completed by heating with an electric heating plate. The device includes a fixing assembly to limit the movement of the T-shaped extrusion rod, preventing accidental activation by workers and improving the stability of the device during operation. It has strong practicality.

[0004] In existing technologies, hot water in water pipes is used to preheat plastic masterbatch, thereby improving the efficiency of plastic particle melting. However, in actual operation, it has been found that plastic particles of different sizes may be produced during the production process. Due to the difference in size, these particles cannot melt at the same time, resulting in some particles not melting completely. This leads to differences in the melting time of plastic particles, which in turn affects and reduces work efficiency. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please refer to the attached diagram. Figures 1-6 As shown in the figure, a plastic melting device for producing biodegradable plastic tableware according to an embodiment of the present invention includes a body 1; an inertial shaft 12 is rotatably connected to the side wall of the body 1; an inertial plate 13 is fixedly connected to the inertial shaft 12; multiple sets of inertial plates 13 are provided; an inclined plate 11 is fixedly connected to the side wall of the body 1 above the inertial plate 13; a filter plate 7 is provided above the inclined plate 11; a movable chamber 2 is fixedly connected to the side wall of the body 1; a bidirectional lead screw 4 is rotatably connected inside the movable chamber 2; and a screw is threaded onto the bidirectional lead screw 4. A slider 3 is connected to the filter plate 7; a scraper 8 is fixedly connected to the side wall of the slider 3; the bottom of the scraper 8 abuts against the surface of the filter plate 7; a gear 32 and a gear 33 are rotatably connected to the side wall of the machine body 1; the output end of the inertia shaft 12 is fixedly connected to the input end of the gear 32; the output end of the gear 33 is fixedly connected to the input end of the bidirectional lead screw 4; a connecting belt 34 is sleeved on the gear 32 and the gear 33; a collection bin 27 is fixedly connected to both sides of the machine body 1; the collection bin 27 is arranged parallel to the filter plate 7;

[0028] In existing technology, hot water in a water pipe is used to preheat the plastic masterbatch to improve the melting efficiency of the plastic granules. However, in actual operation, it has been found that plastic granules of different sizes may be produced during the production process. These granules, due to their size differences, cannot melt at the same time, resulting in some granules not melting completely. This variation in melting time affects and reduces work efficiency. To prevent this, the plastic granules are first poured into the machine body 1, then fall onto the filter plate 7. The filter plate 7 filters out appropriately sized plastic granules, while larger granules are retained on it. Simultaneously, the filtered plastic granules fall onto the inclined plate 11 below, where they slide down due to inertia. At plate 13, an impact occurs, causing plate 13 to rotate, which in turn rotates inertia shaft 12. Simultaneously, inertia shaft 12 rotates, driving external gear 32 to rotate. This, in turn, drives gear 33 via belt 34, which in turn drives bidirectional lead screw 4 in moving chamber 2. The rotation of bidirectional lead screw 4 causes slider 3 and scraper 8 to move back and forth on filter plate 7, cleaning up plastic particles trapped on the filter plate 7 and preventing blockage. The cleaned plastic particles reach the collection bins 27 on both sides for final collection. The filtered plastic particles then melt below the machine body 1. The filter plate 7 effectively traps larger plastic particles, and the inertia plate 13 allows for cleaning during particle fall, saving energy costs.

[0029] like Figures 3-6 As shown, a plate 9 is fixedly connected to the side wall of the body 1; a telescopic spring 10 is fixedly connected to the top of the plate 9; the end of the telescopic spring 10 away from the plate 9 is fixedly connected to the filter plate 7; the filter plate 7 is slidably disposed within the plate 9; a driven column 28 is rotatably connected to the side wall of the body 1 below the filter plate 7; a striking column 29 is fixedly connected to the driven column 28; a striking spring 30 is fixedly connected inside the striking column 29; a striking head 31 is fixedly connected to the end of the striking spring 30 away from the striking column 29; the striking head 31 is slidably disposed within the striking column 29; a gear 35 is rotatably connected to the side wall of the body 1; the output end of the gear 35 is fixedly connected to the input end of the driven column 28; a connecting column 5 is fixedly connected to the side wall of the slider 3; the connecting column 5 passes through the movable chamber 2; the end of the connecting column 5 away from the slider 3 is fixedly connected to the drive rack 6; the drive rack 6 meshes with the gear 35.

[0030] During operation, as the slider 3 moves, it drives the connecting column 5 and the drive rack 6 to move together. As the drive rack 6 moves, it drives the gear 35 to rotate, which in turn drives the driven column 28 to rotate within the machine body 1. When the driven column 28 rotates, it drives the striking column 29 and the striking head 31 to strike the filter plate 7. When the striking head 31 contacts the filter plate 7, it also compresses the striking spring 30. The striking spring 30 prevents the striking head 31 from making hard contact with the filter plate 7, which could cause damage to the filter plate 7. After the striking head 31 strikes the filter plate 7, the filter plate 7 vibrates. In this state of vibration, it compresses the telescopic spring 10. At the same time, the telescopic spring 10 rebounds and drives the filter plate 7 to vibrate again. In this state of vibration, it prevents plastic particles from getting stuck inside the filter plate 7 and causing blockage.

[0031] like Figure 3 As shown, a melting chamber 14 is provided inside the body 1; the melting chamber 14 is located below the inclined plate 11; a base 15 is slidably connected inside the melting chamber 14; an adsorption plate 16 is placed inside the base 15; a fan mechanism 36 is provided on the side wall of the melting chamber 14; the fan mechanism 36 is located above the adsorption plate 16.

[0032] During operation, the plastic granules pass through the inertial plate 13 after filtration and enter the melting chamber 14, where they begin to melt. During operation, the plastic granules emit toxic gases, which are then adsorbed by the adsorption plate 16. The gases are then discharged by the fan mechanism 36. After the melting process is completed, the base 15 can be removed and the adsorption plate 16 can be replaced to prevent the adsorption plate 16 from losing its adsorption capacity after long-term operation.

[0033] like Figure 3 As shown, a snap-fit ​​box 17 is fixedly connected to the outer wall of the melting chamber 14 at the base 15; a slide plate 18 is slidably connected inside the snap-fit ​​box 17; a snap-fit ​​spring 20 is fixedly connected to the side wall of the slide plate 18; a snap-fit ​​block 201 is fixedly connected to the end of the snap-fit ​​spring 20 away from the slide plate 18; a snap-fit ​​groove 21 is opened on the side wall of the base 15; the inner diameter of the snap-fit ​​groove 21 is the same as the size of the snap-fit ​​block 201; a return spring 19 is fixedly connected to the end of the slide plate 18 away from the snap-fit ​​spring 20; the end of the return spring 19 away from the slide plate 18 is fixedly connected to the snap-fit ​​box 17; a pull rod 22 is fixedly connected to the side wall of the slide plate 18; the pull rod 22 passes through the snap-fit ​​box 17.

[0034] When disassembling the base 15 and the adsorption plate 16 during operation, first pull the lever 22 on the outside of the snap-fit ​​box 17. Pulling the lever 22 causes the sliding plate 18 to press against the return spring 19, simultaneously pulling the snap-fit ​​block 201 out of the snap-fit ​​slot 21. After pulling it out, the operator can remove the base 15. After removal, releasing the lever 22 causes the return spring 19 to spring back, ejecting the snap-fit ​​block 201 from the snap-fit ​​box 17 and engaging it. After replacing the adsorption plate 16, the base 15... When the base 15 is inserted into the melting chamber 14, the bottom of the base 15 contacts the snap-fit ​​block 201 and presses the snap-fit ​​block 201 into the snap-fit ​​box 17, which in turn compresses the snap-fit ​​spring 20. When the base 15 reaches the bottom of the melting chamber 14 and the snap-fit ​​groove 21 is parallel to the snap-fit ​​block 201, the snap-fit ​​spring 20 rebounds and pushes the snap-fit ​​block 201 into the snap-fit ​​groove 21 to achieve snap-fit. The snap-fit ​​box 17 facilitates the entry and exit of the base 15 and the replacement of the adsorption plate 16.

[0035] like Figure 2 As shown, a discharge pipe 23 is fixedly connected to the bottom of the melting chamber 14; a discharge valve 24 is fixedly connected to the discharge pipe 23.

[0036] During operation, the molten plastic will be discharged from the discharge pipe 23, and the discharge valve 24 can control the opening and closing of the discharge pipe 23.

[0037] like Figure 1 and Figure 2 As shown, a support leg 25 is fixedly connected to the bottom of the melting chamber 14; a rubber pad 26 is fixedly connected to the bottom of the support leg 25.

[0038] When the filter plate 7 is struck during operation, the body 1 may shake. The shaking can be relieved by the support leg 25, and the rubber pad 26 can prevent the support leg 25 from slipping.

[0039] like Figure 3 As shown, the adsorption plate 16 is an activated carbon plate;

[0040] When in operation, the activated carbon plate can adsorb toxic substances.

[0041] The working principle of this utility model is as follows: In the prior art, hot water in a water pipe is used to preheat the plastic masterbatch, thereby improving the melting efficiency of the plastic particles. However, in actual operation, it has been found that plastic particles of different sizes may be produced during the production process. Due to the difference in size, these particles cannot melt at the same time, resulting in some particles not melting completely. This leads to differences in the melting time of the plastic particles, which in turn affects and reduces work efficiency. To prevent this from happening, firstly, the plastic particles are poured into the machine body 1, and then the plastic particles fall onto the filter plate 7. The filter plate 7 filters out plastic particles of appropriate size, while larger plastic particles are retained on the filter plate 7. At the same time, the filtered plastic particles fall onto the inclined plate 11 below, where they slide down the inclined plate 11. The plastic particles fall onto the inertia plate 13 and impact it, causing the inertia plate 13 to rotate. This rotation, in turn, causes the inertia shaft 12 to rotate. The rotation of the inertia shaft 12 drives the external gear 32 to rotate, which in turn drives the gear 33 to rotate via the connecting belt 34. This, in turn, drives the bidirectional lead screw 4 in the moving chamber 2 to rotate. The rotation of the bidirectional lead screw 4 causes the slider 3 and scraper 8 to move back and forth on the filter plate 7 to clean up the plastic particles trapped on the filter plate 7, preventing the filter plate 7 from becoming clogged due to excessive trapping. The cleaned plastic particles will reach the collection bins 27 on both sides for final collection. The filtered plastic particles will then reach the bottom of the machine body 1 for melting. The filter plate 7 can trap larger plastic particles, and the inertia plate 13 allows for cleaning during the falling of the plastic particles, saving energy costs.

[0042] As the slider 3 moves, it drives the connecting column 5 and the drive rack 6 to move together. As the drive rack 6 moves, it drives the gear 35 to rotate, which in turn drives the driven column 28 to rotate within the machine body 1. When the driven column 28 rotates, it drives the striking column 29 and the striking head 31 to strike the filter plate 7. When the striking head 31 contacts the filter plate 7, it also compresses the striking spring 30. The striking spring 30 prevents the striking head 31 from making hard contact with the filter plate 7, which could cause the filter plate 7 to break. After the striking head 31 strikes the filter plate 7, the filter plate 7 vibrates. In the vibrating state, it compresses the telescopic spring 10. At the same time, the telescopic spring 10 rebounds and drives the filter plate 7 to vibrate again. In the vibrating state, it prevents plastic particles from getting stuck in the filter plate 7 and causing blockage.

[0043] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
