[0029] The following will refer to the attached Figures 1 to 8 The embodiments of the present invention are described in detail. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0030] A heat compression treatment device for heat-resistant and degradable plastics, as shown in the attached Figure 1 , Figure 8 As shown, it includes a fixing frame 7 and a heating cylinder 5 fixedly arranged on the fixing frame 7. The heating cylinder 5 is vertically arranged, and a bottom plate 6 is movably provided at the bottom. A pressing cylinder 4 is arranged in the heating cylinder 5. Specifically, in this embodiment, the fixing frame 7 is "L"-shaped, and a fixing block 11 is arranged on the peripheral side of the bottom horizontal part. The fixing frame 7 can be fixed by the fixing block 11. A plurality of fixing rods 17 are arranged on the left vertical part. The heating cylinder 5 is fixed to the fixing frame 7 by one of the fixing rods 17. The working principle is to bring the pressing cylinder 4 close to the bottom plate 6, and at the same time, a certain heating device (not shown in the figure) is arranged on the peripheral side of the heating cylinder 5 to realize the heat compression treatment of the plastic in the heating cylinder 5. After the heat compression treatment is completed, the bottom plate 6 is opened to take out the treated plastic. This part is the existing technology and will not be described in detail here.

[0031] As attached Figure 1 , Figure 3 , Figure 4As shown, a first plate body 14 is fixedly provided at the bottom of the pressing cylinder 4, a second plate body 15 is provided at the bottom of the first plate body 14 for sealing and rotation, and the second plate body 15 is sealed and slidably connected with the heating cylinder 5 in the vertical direction. The first plate body 14 and the second plate body 15 are provided with matching through holes, that is, when the first plate body 14 and the second plate body 15 rotate relative to each other, the through holes on the first plate body 14 and the second plate body 15 can correspond or stagger, and a ring body 9 is provided near the upper peripheral side of the pressing cylinder 4, and the ring body 9 is connected to the pressing cylinder 4 through a ball thread, and is located above the ring body 9 on the peripheral side of the pressing cylinder 4 A limit baffle A16 is provided, the ring body 9 is slidably connected to the fixed frame 7 along the vertical direction, and a limit spring A10 is provided. Specifically, a slide groove 12 along the vertical direction is provided on the vertical part of the fixed frame 7, one of the fixed rods 17 is slidably set in the slide groove 12, and a limit spring A10 is set between the bottom of the slide groove 12, and the fixed rod 17 is fixedly connected to the ring body 9. In a natural state, the ring body 9 is at a certain height due to the action of the limit spring A10, and also includes a first control mechanism 13 for controlling the up and down movement of the pressing cylinder 4.

[0032] Working principle: when the pressing cylinder 4 moves downward, it moves relative to the ring body 9 in the vertical direction, and rotates under the action of the ring body 9, and at the same time drives the first plate body 14 to rotate, so that the first plate body 14 rotates and moves downward. Since the second plate body 15 is slidably connected with the heating cylinder 5 in the vertical direction, it only moves vertically and does not rotate. When the pressing cylinder 4 moves to the limit baffle A16 and contacts the ring body 9, the pressing cylinder 4 can no longer move relative to the ring body 9 in the vertical direction, so it drives the ring body 9 to move downward together, and the pressing cylinder 4 and the first plate body 14 no longer rotate. At this time, the through holes on the first plate body 14 and the second plate body 15 are staggered, forming a seal for the heating cylinder 5.

[0033] In specific work, the initial state can refer to the attached Figure 1 At this time, the ring body 9 is at a certain height, and the through holes on the first plate body 14 and the second plate body 15 are also in a corresponding state. At this time, the crushed plastic is thrown into the top of the pressing cylinder 4, and the plastic can directly fall into the heating cylinder 5 through the through holes on the first plate body 14 and the second plate body 15, and is supported by the bottom plate 6. After the feeding is completed, the pressing cylinder 4 is controlled to move downward by the first control mechanism 13, and at the same time, the pressing cylinder 4 drives the first plate body 14 to rotate until the limit baffle A16 contacts the ring body 9 and no longer rotates. At this time, the through holes on the first plate body 14 and the second plate body 15 are staggered, and the heating cylinder 5 forms a closed space, and then the pressing cylinder 4 continues to move downward to reduce the internal space of the heating cylinder 5, and at the same time, the heating cylinder 5 is heated around the side to achieve thermal compression treatment of the plastic. Finally, the bottom plate 6 is opened, the plastic after thermal compression treatment is taken out, and then reset to the initial state to complete a thermal compression treatment.

[0034] When controlling the movement of the pressing cylinder 4, the present invention can automatically control the heating cylinder 5 to be sealed. It is only necessary to feed materials into the pressing cylinder 4, eliminating the steps of opening and closing the feeding port, which can greatly save time and improve production efficiency. Moreover, since the heating cylinder 5 is vertically arranged, the plastic after heat compression treatment can be automatically moved out of the heating cylinder 5 through the movement of the bottom plate 6, so that the treated plastic is easy to take out, and the plastic fed into the heating cylinder 5 can be more evenly distributed in the heating cylinder 5 by gravity, which is beneficial to heat compression treatment.

[0035] In addition, it should be noted that in the present embodiment, the first plate body 14 and the second plate body 15 have the same structure. In actual operation, since a portion of the pressing cylinder 4 must extend into the heating cylinder 5, in order to ensure that the thread on the pressing cylinder 4 can smoothly extend into the heating cylinder 5, the diameter of the pressing cylinder 4 and the first plate body 14 may also be slightly smaller than the second plate body 15. The specific production and manufacturing can be carried out according to actual conditions.

[0036] In addition, it should be noted that the present invention is for heat compression treatment of degradable plastics (such as disposable lunch boxes), which are relatively light in weight. When the crushed plastics are put into the heating tube 5, the limit spring A10 will not be compressed due to the excessive weight of the plastics.

[0037] As attached Figure 1 , Figure 2 As shown, in this embodiment, a filter mechanism 2 is provided above the pressing cylinder 4, and the filter mechanism 2 is relatively fixed to the fixing frame 7. The filter mechanism 2 includes a filter plate 203 and a filter hole 202 arranged on the filter plate 203, and the filter hole 202 corresponds to the pressing cylinder 4. When in specific use, the crushing device is arranged above the filter mechanism 2, and the filter mechanism 2 can play a certain filtering role to filter out plastics that are not crushed thoroughly enough.

[0038] As attached Figure 1 , Figure 2 , Figure 8 As shown, in this embodiment, the filtering mechanism 2 also includes a limit baffle B201 arranged on the left and right sides of the filter plate 203, and also includes a pushing mechanism 1 and a storage mechanism 3. The pushing mechanism 1 includes a rodless cylinder 101 fixedly arranged at the top of the vertical part of the fixed frame 7. The rodless cylinder 101 is connected to a pushing plate 103 along the front and rear direction through a connecting rod 102. The pushing plate 103 is located above the filter plate 203. The storage mechanism 3 includes a guide plate 302 fixedly arranged below the filter plate 203. The guide plate 302 is a hollow prism shape, the top corresponds to the filter hole 202, and a limit baffle C303 is provided on the bottom side.

[0039] During specific operation, the crushed plastic first falls on the filter plate 203. The plastic that meets the crushing standards can pass through the filter plate 203 smoothly and enter the pressing cylinder 4 and the heating cylinder 5. The plastic that does not meet the crushing standards stays on the filter plate 203. Through the movement of the pushing plate 103, the plastic that does not meet the crushing standards is pushed out of the filter plate 203, and falls on the bottom side of the guide plate 302 through the guide plate 302 and the limit baffle C303 for storage, which can improve the quality of the hot compression treatment.

[0040] As attached Figure 1 , Figure 2 , Figure 8 As shown, in this embodiment, the guide plate 302 is fixedly connected to the fixed frame 7 by a fixed rod 17, and the limit baffle C303 is rotatably connected to the guide plate 302. The limit baffle C303 is provided with a discharge port and a matching sealing plate 301. By rotating the limit baffle C303 and the sealing plate 301, it is convenient to take out the plastic that does not meet the crushing standard.

[0041] As attached Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, in this embodiment, a through hole is opened on the filter plate 203, and the first control mechanism 13 includes a fixed tube 1301 fixedly arranged in the through hole, a fixed plate 1308 is fixedly arranged in the fixed tube 1301, a rotating tube 1307 is rotatably penetrated by the fixed plate 1308, a lifting rod 1305 is connected in the rotating tube 1307 by a ball thread along the vertical direction, a hemispherical pressure block 1304 is provided on the top of the lifting rod 1305, the pressure block 1304 is slidably arranged in the through hole along the vertical direction, a limit spring B1306 is provided between the bottom of the pressure block 1304 and the fixed plate 1308, a rotating plate 1309 is fixedly arranged at the bottom of the rotating tube 1307, a telescopic cylinder A1302 is fixedly arranged at the bottom of the rotating plate 1309, the bottom of the telescopic cylinder A1302 is rotatably connected to the first plate body 14, and a pushing rod 1303 is provided.

[0042] Working principle: Under the natural state, the pressure block 1304 is limited by the spring B1306, and the top is higher than the filter plate 203. When the push plate 103 moves back and forth, the push plate 103 will press the pressure block 1304, causing the pressure block 1304 to move up and down, thereby driving the lifting rod 1305 to move up and down, thereby driving the rotating tube 1307 to rotate, thereby driving the rotating plate 1309 to rotate, thereby driving the telescopic cylinder A1302 to rotate, thereby driving the pushing rod 1303 to rotate.

[0043] During specific operation, when feeding in the initial state, the push plate 103 can be controlled to move. After the feeding is completed, the push plate 103 continues to be controlled to move for a while, driving the push rod 1303 to rotate, which can not only play a filtering role, but also can ensure that the plastic that falls into the pressing cylinder 4 can be smoothly pushed into the heating cylinder 5 through the push rod 1303. The structure is simple and easy to use.

[0044] As attached Figure 1 , Figure 6 , Figure 7 As shown, in this embodiment, a second control mechanism 8 for controlling the movement of the base plate 6 is provided on the fixed frame 7. The second control mechanism 8 includes a telescopic cylinder B801 fixedly arranged on the vertical part of the fixed frame 7. The telescopic cylinder B801 is along the vertical direction. The telescopic cylinder B801 is fixedly connected with a lifting plate 802. A support plate 806 is provided on one side of the lifting plate 802. The lifting plate 802 and the support plate 806 are telescopically connected along the horizontal direction and are provided with a limit spring C805. Specifically, the lifting plate 802 is fixedly connected with a sliding rod 804. The sliding rod 804 is slidably penetrated through the support plate 806. The limit spring C805 is provided between the sliding rod 804 and the support plate 806. A guide plate 803 is provided between the lifting plate 802 and the support plate 806. The guide plate 803 is fixedly arranged on the fixed frame 7. The guide plate 803 includes a vertical portion and an inclined portion arranged up and down, wherein the inclined portion is inclined to the lower right. The base plate 6 is fixedly arranged on the support plate 806.

[0045] Working principle: The telescopic cylinder B801 drives the lifting plate 802 and the support plate 806 to move up and down. When the support plate 806 is lifted or lowered, it is acted upon by the guide plate 803. When the support plate 806 moves to the inclined portion, the inclined portion pushes the support plate 806 to move in the horizontal direction.

[0046] During specific use, when the plastic is subjected to heat compression treatment, the telescopic cylinder B801 drives the bottom plate 6 to be close to the heating tube 5. When the heat compression treatment is completed, the heating tube 5 is first knocked to disconnect the adhesion between the plastic after the heat compression treatment and the heating tube 5. Then the telescopic cylinder B801 is controlled to drive the lifting plate 802 and the support plate 806 to move. The lifting plate 802 always descends, and the support plate 806 drives the plastic after the heat compression treatment to descend first, so that the plastic after the heat compression treatment is completely separated from the heating tube 5. Then the support plate 806 drives the plastic after the heat compression treatment to move to the lower right, so that the plastic after the heat compression treatment is completely exposed to the outside, so as to facilitate removal. After removal, the telescopic cylinder B801 drives the lifting plate 802 to reset, and the support plate 806 drives the bottom plate 6 to reset together under the action of the limiting spring C805.
