Description

Technical Field

[0001] The present application relates to the technical field of engineering plastic recycling, and particularly relates to an energy-saving and environment-friendly engineering plastic recycling granulation melting device. Background Art

[0002] Engineering plastics can be used as engineering materials and raw materials to replace metals in manufacturing mechanical parts. They have the advantages of strong comprehensive performance, high mechanical strength, and good insulation. Even when recycled, they have extremely high use value. When engineering plastics are recycled, they are generally remelted and granulated in a furnace. After the recycled engineering plastics that have been cleaned and dried become a high-temperature flowable molten state through the spiral extrusion part inside the heating device, they generally enter a specific mold through the extrusion end at the outlet of the heating device, that is, a mold with multiple groups of holes. The engineering plastics in a high-temperature molten flow state will flow into the joint between the mold and the outlet of the heating device. Driven by the spiral rotating parts inside the heating device, the engineering plastics enter the internal holes of the mold one after another, thus forming multiple long and narrow continuous strips. The subsequent strips will flow through cooling water to form a shape, and then undergo final cutting and granulation. However, since the engineering plastics cannot rotate during the movement process, when they pass through the joint part between the outlet of the heating device and the inlet of the mold, some materials come into long-term contact with the body part at the inlet of the mold, and the limited space inside the device will cause some materials to stay at the body part at the inlet end of the mold for a long time, generating an eddy current phenomenon similar to that when water flows. Moreover, the newly heat-formed engineering plastics will continue to move forward and preferentially enter the mold holes, which causes a part of the engineering plastics at the joint part to be unable to be discharged in time, resulting in unsmooth discharge of materials. In addition, the mechanical properties of the engineering plastics that are at a high temperature for a long time and cannot be discharged may also be affected to a certain extent, which urgently needs to be solved.

[0007] Connecting columns and support rings are fixedly connected to the inner wall of the transfer cylinder. A support column is rotatably installed inside the support ring. A rotating block located inside the cavity of the transfer cylinder and a first fixing plate located inside the cavity of the connecting cylinder are respectively fixedly installed on the outer surface of the support column. The first fixing plate is inclined and abuts against the inner wall of the connecting cylinder in a matching manner. A plurality of scraping plates are fixedly installed on the left side of the rotating block, and the scraping plates abut against the end face of the mold. A placement groove is formed on the outer peripheral surface of the rotating block, and a second fixing plate is fixedly connected to one end of the placement groove on the outer side.

[0008] Preferably, a fixing strip is fixedly connected to one side of the inner wall of the placement groove facing the second fixing plate. A rotating column is movably sleeved inside the placement groove. A moving strip is fixedly connected to the end face of the rotating column. A first spring and a second spring are elastically connected between the moving strip and the fixing strip.

[0009] Preferably, both the first spring and the second spring are designed to have a semi-circular shape. When the first spring and the second spring are not stressed, the second fixing plate is in an inclined state.

[0010] Preferably, limiting strips are fixedly installed on both sides of the bottom of the second fixing plate, and the limiting strips are in sliding contact with the surface of the rotating block.

[0011] Preferably, the number of the scraping plates is four groups, and the four groups of scraping plates are evenly distributed around the axis of the support column on the left side of the rotating block.

[0013] Preferably, a second bolt is installed in a threaded manner at the abutting portion between the connecting cylinder and the transfer cylinder. The connecting cylinder and the transfer cylinder are press-fitted and installed through the second bolt.

[0015] Preferably, the four groups of connecting columns are four groups that are evenly distributed in a circumferential manner at equal intervals. The two ends of the connecting columns are respectively fixedly connected to the inner wall of the transfer cylinder and the outer surface of the support ring.

[0016] Preferably, the number of the first fixing plates and the second fixing plates is the same, and the inclination directions of the first fixing plates and the second fixing plates are the same.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. This device has been redesigned and optimized, and relevant structures including a connecting cylinder, a transfer cylinder, and a scraper are added between the melting cylinder and the mold, realizing the smooth discharge function of the material during the operation of the device. The heated and molten material flows leftward through the inside of the connecting cylinder, continuously pushing the first fixing plate to rotate, driving the support column, the rotating block, and the scraper to perform circular motion. The scraper slides and abuts against the right end face of the mold to synchronously scrape the feeding end of the mold. When the material enters the inner cavity of the transfer cylinder and is filled, the scraper can scrape and drive the material accumulated on the solid part at the right end of the mold, enabling it to pass through the forming holes smoothly and be formed, avoiding material accumulation and significantly improving the discharging efficiency of the device.

[0019] 2. This device also has the rotating block rotating with the support column, driving the second fixing plate and the limiting strip to perform circular motion in the inner cavity of the transfer cylinder. When the material accumulates and fills the inner cavity of the transfer cylinder, the first fixing plate drives the support column, the rotating block, and the second fixing plate to stir the material. On the one hand, the inclined second fixing plate further accelerates the rotation speed of the support column and the fixing strip, improving the scraping efficiency of the fixing strip. On the other hand, due to the rotatable characteristics of the second fixing plate and the rotating column, when the second fixing plate contacts the material, it is pushed by the resistance and rotates. At this time, the rotating column drives the moving strip to rotate, applying pressure to the first spring and stretching the second spring to generate a reaction force, causing the second fixing plate to generate a reaction force and applying pressure to the material in the transfer cylinder. At this time, the material as a whole has a rotational tendency under the reaction force of the second fixing plate, so that the material entering the end face of the mold has a rotational tendency at one end, reducing the accumulation degree of the material at the feeding end face of the mold.

[0020] 3. The number and inclination directions of the first fixing plate and the second fixing plate are the same, enabling both the first fixing plate and the second fixing plate to convert the horizontal thrust from the material into the power for the circular motion of the support column, the rotating block, and the scraper. This design does not use additional electric energy and other structures at all, effectively reducing the complexity and manufacturing cost of the device. Inside the connecting cylinder and the transfer cylinder, the kinetic energy of the material flow is used for auxiliary work, causing the material to have a tendency to rotate around the axis of its own flow direction during the horizontal flow process, making the movement of the material more efficient and preventing material accumulation.

Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0034] Please refer to Figures 1 - 9 , this embodiment discloses an energy-saving and environment-friendly engineering plastic recycling and granulation melting device, including:

[0035] Heating mechanism, the heating mechanism includes a melting cylinder 1, a feeder 2 is installed at the top of the melting cylinder 1, a motor 3 is installed on the right side of the melting cylinder 1, an output shaft of the motor 3 is fixedly installed with a screw 4 located inside the melting cylinder 1, and a heater 5 is installed on the outer side of the melting cylinder 1;

[0036] On the left side of the motor 3, a connecting cylinder 7 is fixedly installed, on the left side of the connecting cylinder 7, a transfer cylinder 8 is fixedly installed, on the left side of the transfer cylinder 8, a mold 9 is fixedly installed, and a plurality of forming holes 12 are formed inside the mold 9;

[0037] The inner wall of the transfer cylinder 8 is fixedly connected with a connecting column 14 and a support ring 15. A support column 16 is rotatably installed inside the support ring 15. An outer surface of the support column 16 is fixedly installed with a rotating block 19 located inside the cavity of the transfer cylinder 8 and a first fixing plate 18 located inside the cavity of the connecting cylinder 7. The first fixing plate 18 is inclined and abuts against the inner wall of the connecting cylinder 7. On the left side of the rotating block 19, a plurality of scraping plates 20 are fixedly installed, and the scraping plates 20 abut against the end face of the mold 9. A placement groove 21 is formed on the outer peripheral surface of the rotating block 19, and an outer end of the placement groove 21 is fixedly connected with a second fixing plate 27;

[0038] This device has been redesigned and optimized. A related structure including a connecting cylinder 7, a transfer cylinder 8 and a scraping plate 20 is added between the melting cylinder 1 and the mold 9, realizing the smooth discharge function of the material during the operation of the device. The heated and molten material flows leftward through the inside of the connecting cylinder 7, continuously pushing the first fixing plate 18 to rotate, driving the support column 16, the rotating block 19 and the scraping plate 20 to make a circular motion. The scraping plate 20 slides and abuts against the right end face of the mold 9 to synchronously scrape the feeding end of the mold 9. When the material enters the cavity of the transfer cylinder 8 and is filled, the scraping plate 20 can scrape and drive the material accumulated on the solid part at the right end of the mold 9, so that it can smoothly pass through the forming holes 12 and be formed, avoiding the accumulation of materials and significantly improving the discharging efficiency of the device.

[0039] 2. An energy-saving and environment-friendly engineering plastic recycling and granulation melting device according to claim 1, wherein a fixing strip 22 is fixedly connected to a side of the inner wall of the placement groove 21 facing the second fixing plate 27. A rotating column 23 is movably sleeved inside the placement groove 21. An end face of the rotating column 23 is fixedly connected with a moving strip 24. A first spring 25 and a second spring 26 are elastically connected between the moving strip 24 and the fixing strip 22;

[0040] The placement groove 21 provides rotational support for the rotating column 23 and the second fixing plate 27. When the material accumulates in the cavity of the transfer cylinder 8, it can synchronously apply pressure around the axis of the transfer cylinder 8 to the material passing through the outer peripheral surface of the rotating block 19, so that the leftward moving material can have a tendency to rotate around its own axis, avoiding the accumulation of materials on the solid part of the end face of the mold 9.

[0041] The device also has a rotating block 19 rotating with the support column 16, driving the second fixing plate 27 and the limiting strip 28 to move in a circular motion inside the middle transfer cylinder 8. When materials accumulate and fill the inside of the middle transfer cylinder 8, the support column 16, the rotating block 19 and the second fixing plate 27 are driven by the first fixing plate 18 to stir the materials. On the one hand, the second fixing plate 27 with an inclined design further accelerates the rotation speed of the support column 16 and the fixing strip 22, improving the scraping efficiency of the fixing strip 22. On the other hand, due to the rotatable characteristics of the second fixing plate 27 and the rotating column 23, when the second fixing plate 27 contacts the materials, it is pushed by the resistance and rotates on its own. At this time, the rotating column 23 drives the moving strip 24 to rotate, presses on the first spring 25, stretches the second spring 26 to generate a reaction force, so that the second fixing plate 27 generates a reaction force and presses on the materials located in the middle transfer cylinder 8. At this time, the materials will have an overall rotation tendency under the reaction force of the second fixing plate 27, so that the materials entering the end face of the mold 9 will have a rotation tendency at one end, reducing the accumulation degree of the materials at the feeding end face of the mold 9.

[0042] Among them, both the first spring 25 and the second spring 26 are designed to have a semicircular shape. When the first spring 25 and the second spring 26 are not stressed, the second fixing plate 27 is in an inclined state;

[0043] The first spring 25 and the second spring 26 are located between the moving strip 24 and the fixing strip 22. When the rotating column 23 rotates, it will compress the first spring 25 and stretch the second spring 26, making the rotating column 23 and the second fixing plate 27 generate a rotational elastic force, so that the second fixing plate 27 presses on the materials in the reverse direction, enabling the materials to generate a force to rotate around the axis of their own flow direction.

[0044] Among them, two sides at the bottom of the second fixing plate 27 are fixedly installed with limiting strips 28, and the limiting strips 28 are in sliding contact with the surface of the rotating block 19;

[0045] The rotating column 23 is movably sleeved on the inner wall of the placement groove 21. The second fixing plate 27 is fixedly installed with a limiting strip 28 on the surface facing the rotating block 19, and the limiting strip 28 is in sliding contact with the surface of the rotating block 19, keeping the relative displacement between the surface of the second fixing plate 27 and the rotating block 19 unchanged and maintaining the stability of the second fixing plate 27.

[0046] Among them, the number of the scraping plates 20 is four groups, and the four groups of scraping plates 20 are evenly distributed around the axis of the support column 16 on the left side of the rotating block 19;

[0047] The scraping plate 20 makes a circular motion as the support column 16 and the rotating block 19 rotate. Its left side will synchronously scrape the right end of the mold 9, and the materials accumulated on the end face of the mold 9 can also be driven by the rotation of the scraping plate 20 to pass through the area of the forming holes 12, assisting the materials to enter the forming holes 12 to complete the discharging.

[0048] Among them, two groups of base one 6 are fixedly installed at the bottom of the melting cylinder 1, and a base two 13 is fixedly installed at the bottom of the mold 9;

[0049] The base one 6 and the base two 13 serve as the supports for the melting cylinder 1 and the mold 9, and can provide stable support for the device.

[0050] Among them, a bolt two 11 is threadedly installed at the abutting part of the connecting cylinder 7 and the transfer cylinder 8, the connecting cylinder 7 and the transfer cylinder 8 are press-fitted and installed through the bolt two 11, a bolt one 10 is threadedly installed at the abutting part of the transfer cylinder 8 and the mold 9, and the transfer cylinder 8 and the mold 9 are press-fitted and installed through the bolt one 10;

[0051] The connecting cylinder 7 and the transfer cylinder 8 are fixedly installed and fixed through the bolt two 11, and the transfer cylinder 8 and the mold 9 are fixedly installed and fixed through the bolt one 10. The advantage of this structure is that it can be disassembled at any time, which is convenient for maintaining the internal structure.

[0052] Among them, a limiting ring 17 is fixedly installed in the middle of the outer surface of the support column 16, and the left side of the limiting ring 17 abuts against the right side of the support ring 15;

[0053] The limiting ring 17 together with the annular protrusion design enables the support column 16 to maintain a predetermined rotational position within the inner wall of the support ring 15. When the material continuously flows to the left and generates a thrust on the support column 16, the limiting ring 17 just maintains the position and stability of the support column 16 through the limiting abutment with the support ring 15.

[0054] Among them, four groups of connecting columns 14 are evenly distributed in a circle at equal intervals, and both ends of the connecting columns 14 are fixedly connected to the inner wall of the transfer cylinder 8 and the outer surface of the support ring 15 respectively;

[0055] The connecting columns 14 are fixedly connected to the right side of the inner wall of the transfer cylinder 8. Four groups of them are all fixedly connected to the support ring 15, thereby providing a stable fixed support for the support ring 15.

[0056] Among them, the number of the first fixing plate 18 and the second fixing plate 27 is the same, and the inclination directions of the first fixing plate 18 and the second fixing plate 27 are the same;

[0057] The number and inclination directions of the first fixing plate 18 and the second fixing plate 27 are the same, so that both the first fixing plate 18 and the second fixing plate 27 can convert the horizontal thrust from the material into the power for the circumferential movement of the support column 16, the rotating block 19 and the scraping plate 20. This design does not use additional electric energy and other structures at all. Inside the connecting cylinder 7 and the transfer cylinder 8, the kinetic energy of the material flow is used for auxiliary work, so that the material generates a tendency to rotate around the axis of its own flow direction during the horizontal flow process, thereby making the movement of the material more efficient and preventing the material from piling up.

[0058] Working principle:

[0059] When this device is working, the processed recycled engineering plastics, hereinafter referred to as materials, enter the feeder 2 and then enter the inner cavity of the melting cylinder 1. The motor 3 is started to drive the screw 4 to rotate, continuously pushing the materials entering the inner cavity of the melting cylinder 1 to the left. At the same time, the heater 5 is turned on to heat the materials moving to the left in the inner cavity of the melting cylinder 1, so that the materials become a high-temperature molten fluid state under the heating of the heater 5 and discharge from the left side of the melting cylinder 1 into the connecting cylinder 7;

[0060] Then, as Figure 3 、 Figure 4 and Figure 5 show, when the materials pass through the inside of the connecting cylinder 7, they will push the fixed plate 18 and drive the pillar 16, the rotating block 19 and the scraper 20 to rotate. When the inside of the connecting cylinder 7 and the transfer cylinder 8 are filled with materials, the materials will enter the inside of the forming hole 12 for moving and forming. At this time, the four groups of scrapers 20 rotate periodically with the pillar 16 and the fixed plate 18, so as to synchronously scrape the right end face of the mold 9. At the same time, the materials piled up on the right side of the mold 9 rotate and flow as the scraper 20 rotates, which makes the materials originally piled up on the solid part at the right end of the mold 9 just move into the forming hole 12 with the rotation, thus avoiding the long-term accumulation of materials on the right end face of the mold 9;

[0061] At the same time, due to the continuous accumulation and flow of the materials through the inner cavity of the transfer cylinder 8, when the rotating block 19 rotates with the pillar 16, it will drive the fixed plate 27 and the limiting strip 28 to rotate. At this time, one side of the limiting strip 28 contacts the materials during rotation and rotates under the resistance of the materials, and the whole materials move horizontally to the right, making the rotation angle of the fixed plate 27 further increase. At this time, in the inner cavity of the placing groove 21, the rotating column 23 is driven by the fixed plate 27 to rotate, and drives the moving strip 24 to rotate clockwise around the axis of the rotating column 23, compressing the first spring 25 and stretching the second spring 26, so that the fixed plate 27 generates a reaction elastic force when rotating and acts on the materials. At this time, the materials will have an overall rotation tendency under the reaction force of the fixed plate 27. Finally, the materials continue to move through the forming hole 12 and form continuous columnar materials.

[0062] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
