Description

Technical Field

[0002] "Green low organic residue melt extrusion" technology or process has been used in many fields, aiming to achieve low pollution, low emissions or even no emissions during the melting process. These technologies or processes not only help protect the environment, but also improve production efficiency and product quality, and have broad development prospects.

[0003] The melt granulation extrusion molding production process is mainly used for the granulation of polymer materials. This process realizes a green, environmentally friendly and low-organic residue production process through high-temperature mixing pretreatment, high-temperature preheating, step-by-step heating, melt drawing and cutting granulation. At the same time, this process can also effectively reduce the cracking and secondary damage of polymer materials during the granulation process, maintain the polymer material at a low moisture content, and has good environmental protection and sustainability.

[0004] In the prior art, pelletizers for pellet production mostly extrude raw materials through a feed tray and extrude the raw materials through a feed hole to obtain pellets. However, since the raw material barrel is in a high temperature state during the granulation process, the raw materials are also at a high temperature when they are squeezed into the feed tray, which causes the inside of the feed tray to easily adhere to scraps after the granulation is completed. Long-term use makes the feed tray difficult to clean and inconvenient for next use. A green, low-organic residue melt granulation extrusion molding production process is now proposed to solve the above problems. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] like Figures 1 to 8 As shown, the present invention provides a green low organic residue melt granulation extrusion molding production process, the specific production process is as follows:

[0038] S1. Pre-process the materials to be prepared, usually including mixing, drying, melting and other steps to ensure the uniformity and stability of the raw materials;

[0039] S2, preheating the pretreated raw materials at high temperature so that they are easier to heat and mix in the subsequent melting process;

[0040] S3. The raw materials are heated in steps by specific heating equipment to gradually reach a molten state. During this process, the heating temperature and time need to be strictly controlled to ensure the melting effect of the raw materials and the quality of the product.

[0041] S4. Add the molten raw materials to the melt-inflating extruder and granulate them through a specific process and equipment. During this process, the molten raw materials are extruded through the die holes under high pressure and high speed to form the desired pellet shape.

[0042] S5. After melt-inflating and extrusion, the molten material needs to be cooled for subsequent processing and packaging. Melt drawing is one of the cooling methods. The molten material is drawn into filaments through specific equipment to increase its surface area, thereby accelerating the cooling process.

[0043] S6. After cooling, the molten material needs to be cut and granulated to form particles of the required shape and size.

[0044] like Figures 1 to 8 As shown, the present invention provides a green low-organic residue melt granulation extrusion molding production process device, including a mounting plate 1, one side of the mounting plate 1 is fixedly connected to a first motor 2, one end of the first motor 2 is fixedly connected to a threaded sleeve 3, the internal thread of the threaded sleeve 3 is connected to a threaded rod 4, the outside of the threaded sleeve 3 is movably connected to a bearing member 5, one end of the threaded rod 4 is clamped to a raw material barrel 6, one side of the raw material barrel 6 is fixedly connected to a first electric telescopic rod 7, one end of the first electric telescopic rod 7 is clamped to an upper clamping assembly 8, one side of the upper clamping assembly 8 is clamped to a lower clamping assembly 9, the other side of the upper clamping assembly 8 is fixedly connected to a second electric telescopic rod 21, and one side of the lower clamping assembly 9 is fixedly connected to a plurality of discharge columns 10;

[0045] The outer end of each unloading column 10 is fixedly connected to a unloading pad 11, and the outer part of the unloading column 10 is clamped with a unloading tray 12, and the middle part of the outer side of the unloading tray 12 is rotatably connected to a scraper 13, and one side of the scraper 13 is fixedly connected to a second motor 14, and the outer part of the unloading tray 12 is fixedly connected to a limit rod 15, and the inner part of the upper clamping assembly 8 is fixedly connected to a connecting block 16, and the outer part of the connecting block 16 is rotatably connected to a gear 17, and the outer part of the gear 17 is meshed with a tooth plate 18, and one end of the outer part of the raw material barrel 6 is hinged with a pull pin 19, and both sides of the pull pin 19 are fixedly connected to a limit assembly 20;

[0046] The above scheme is adopted: the threaded sleeve 3 is driven to rotate by the first motor 2, the threaded sleeve 3 drives the threaded rod 4 to rotate, the threaded sleeve 3 is threadedly connected to the threaded rod 4, and the threaded rod 4 is clamped with the raw material barrel 6, so that the threaded rod 4 can move into the inside of the raw material barrel 6, and the pusher plate pushes the raw material inside the raw material barrel 6 to the bottom of the raw material barrel 6 through the threaded rod 4. At this time, the threaded rod 4 drives the pusher plate to rotate and move downward, so that the raw material approaches the lower material tray 12, and the raw material is granulated through the discharge hole opened in the discharge tray 12. During the granulation process, the second motor 14 continuously drives the scraper 13 to rotate, and the speed of the scraper 13 driven by the second motor 14 is adapted to the discharge speed, so that the scraper 13 can cut the extruded raw material into particles, which can ensure uniform particle size;

[0047] After the granulation is completed, the pushing plate returns to its original position and presses the limit assembly 20 so that the two ends of the limit assembly 20 are not engaged with the internal card holes of the discharge tray 12, thereby releasing the clamping fixation of the pull pin 19 and the discharge tray 12, and the first electric telescopic rod 7 pushes the discharge tray 12 so that the discharge tray 12 is not connected to the raw material barrel 6. After the discharge tray 12 is away from the raw material barrel 6, the second electric telescopic rod 21 pushes the upper clamping assembly 8 to move, and the first electric telescopic rod 7 pulls the discharge tray 12 back. During the pulling process, the discharge pad 11 abuts against the discharge tray 12, and the discharge pad 11 is pressed into the inside of the discharge tray 12. The discharge column 10 is engaged with the discharge tray 12, and the discharge pad 11 squeezes out the residual scraps inside the discharge tray 12, making it easy to clean the sticky scraps inside the discharge tray, which is convenient for the next granulation.

[0048] like Figure 1 、 Figure 3 and Figure 6 As shown, one side of the carrier 5 is fixedly connected to the mounting plate 1, the outside of the first motor 2 is fixedly connected to the carrier 5, one side of the carrier 5 does not contact the raw material barrel 6, and a threaded hole that is adapted to the size of the threaded rod 4 is opened on one side of the raw material barrel 6. One end of the first electric telescopic rod 7 is fixedly connected to the discharge tray 12, and one side of the first electric telescopic rod 7 is fixedly connected to the mounting plate 1 through a fixing plate;

[0049] The above scheme is adopted: the supporting member 5 is supported and fixed by the mounting plate 1, and the supporting member 5 limits and fixes the threaded sleeve 3 to prevent twisting and dislocation when the first motor 2 drives the threaded sleeve 3 to rotate. One end of the threaded rod 4 is clamped with the raw material barrel 6 so that the threaded sleeve 3 can be driven by the first motor 2 to rotate and move the threaded rod 4, so that the threaded rod 4 can push the pushing plate. One side of the first electric telescopic rod 7 is fixedly connected to the mounting plate 1, and the mounting plate 1 supports the first electric telescopic rod 7. The outside of the raw material barrel 6 is fixedly connected to the mounting plate 1. The mounting plate 1 supports and limits the raw material barrel 6, which can prevent the raw material barrel 6 from shaking when pushing the material.

[0050] like Figure 2 、 Figure 4 、 Figure 6 and Figure 7 As shown, the upper clamping assembly 8 includes an upper clamping disc 801, the outer portion of the upper clamping disc 801 is annular and fixedly connected to upper clamping arc plates 802 at equal distances, and an upper clamping strip 803 is fixedly connected to the same side of each upper clamping arc plate 802. An upper clamping slot of the same size as the first electric telescopic rod 7 is opened on one side of the upper clamping disc 801, and the middle part of one side of the upper clamping disc 801 is fixedly connected to the second electric telescopic rod 21, and one side of each upper clamping strip 803 is fixedly connected to the upper clamping disc 801;

[0051] The lower clamping assembly 9 includes a lower clamping disc 901, the outer portion of the lower clamping disc 901 is annular and fixedly connected to lower clamping arc plates 902 at equal distances, and a lower clamping strip 903 is fixedly connected to the same side of each lower clamping arc plate 902. A lower clamping groove of the same size as the first electric telescopic rod 7 is opened on one side of the lower clamping disc 901, and one side of each lower clamping strip 903 is fixedly connected to the lower clamping disc 901. The upper clamping disc 801 abuts against the lower clamping disc 901, the inner portion of the upper clamping arc plate 802 is clamped to the lower clamping strip 903, and the outer portion of the upper clamping strip 803 is clamped to the lower clamping arc plate 902;

[0052] The above-mentioned scheme is adopted: the inner diameter of the upper clamping plate 801 is equal to the inner diameter of the lower clamping plate 901, the shape and size of the upper clamping arc plate 802 and the lower clamping arc plate 902 are equal, the shape and size of the upper clamping strip 803 and the lower clamping strip 903 are equal, when the upper clamping groove inside the upper clamping arc plate 802 is clamped with the lower clamping strip 903, the upper clamping strip 803 is clamped with the lower clamping groove inside the lower clamping arc plate 902, and the two are clamped together, so that the upper clamping plate 801 and the lower clamping plate 901 are clamped and fixed.

[0053] like Figure 2 、 Figure 3 、 Figure 5 and Figure 8 As shown, a plurality of equally sized discharge holes are provided inside the discharge tray 12. The size of each discharge column 10 is adapted to the size of the discharge hole. The discharge pad 11 is a soft structure. One side of the scraper 13 abuts against the discharge tray 12. The length of the scraper 13 is smaller than the inner diameter of the discharge tray 12.

[0054] One end of the limiting rod 15 is an oblique T-shaped structure, one end of the limiting rod 15 is movably connected to the mounting plate 1, the bottom of the connecting block 16 is movably connected to the mounting plate 1, the outer portion of the tooth plate 18 is fixedly connected to the inner portion of the mounting plate 1, and a card hole adapted to the size of the limiting component 20 is opened inside the unloading tray 12. The bottom of the second electric telescopic rod 21 is fixedly connected to the mounting plate 1, and a fixed rod is rotatably connected to one side of the push plate. The fixed rod is used to limit the push plate. When the push plate moves downward, the fixed rod moves downward. At this time, the upper part of the fixed rod becomes shorter and the lower part becomes longer;

[0055] The above solution is adopted: after the unloading tray 12 is cleaned, the unloading tray 12 is pushed by the first electric telescopic rod 7, and the unloading column 10 is separated from the unloading tray 12. The second electric telescopic rod 21 pulls the lower clamping assembly 9 back to its original position through the upper clamping assembly 8, and twists the lower clamping tray 901, so that the lower clamping arc plate 902 is separated from the upper clamping strip 803, and the lower clamping strip 903 is separated from the upper clamping arc plate 802, so that the lower clamping assembly 9 can be removed for cleaning;

[0056] The interior of the mounting plate 1 is provided with a T-shaped groove that is adapted to the size of the limiting rod 15. The limiting rod 15 can slide along the T-shaped groove. The limiting rod 15 supports and limits the unloading tray 12. The interior of the mounting plate 1 is provided with a limiting groove that is adapted to the size of the connecting block 16 and the tooth plate 18. The tooth plate 18 is fixedly connected to the interior of the mounting plate 1, and the connecting block 16 is movably connected to the interior of the mounting plate 1, so that the connecting block 16 can slide along the limiting groove. The gear 17 rotates when the connecting block 16 moves and engages with the tooth plate 18. The tooth plate 18 limits the gear 17.

[0057] The working principle and use process of the present invention:

[0058] First, the first motor 2 drives the threaded sleeve 3 to rotate. The threaded sleeve 3 moves the threaded rod 4 through the thread. The threaded rod 4 pushes the push plate to push the raw material through the raw material barrel 6 to the lower feeding tray 12. At this time, the raw material is squeezed into the feeding hole through the feeding tray 12. At the same time as the material is discharged, the second motor 14 drives the scraper 13 to rotate. At this time, the scraper 13 cuts the material into particles, thereby performing granulation.

[0059] When the push plate abuts against the discharge tray 12, the raw materials inside the raw material barrel 6 have been granulated. At this time, the power supply of the first motor 2 is disconnected, and the two ends of the limit assembly 20 are released from the inside of the discharge tray 12 by pressing the limit assembly 20. At this time, the pull pin 19 releases the limit fixation of the discharge tray 12, and the discharge tray 12 is pushed to move by the first electric telescopic rod 7. At this time, the limit rod 15 moves along the inside of the mounting plate 1 through the discharge tray 12, and the first electric telescopic rod 7 is away from the raw material barrel 6;

[0060] After the discharge tray 12 is no longer in contact with the raw material barrel 6, the second electric telescopic rod 21 pushes the upper clamping assembly 8 and the lower clamping assembly 9 to move. When the first electric telescopic rod 7 is clamped with the upper clamping assembly 8 and the lower clamping assembly 9, the first electric telescopic rod 7 pulls the discharge tray 12 back. At this time, the discharge hole inside the discharge tray 12 abuts against the discharge column 10, and the discharge tray 12 continues to move, so that the discharge column 10 and the discharge pad 11 are squeezed into the discharge hole. At this time, the residual scraps inside the discharge hole are squeezed out of the discharge tray 12, so that the discharge hole is cleaned;

[0061] After the discharge tray 12 is cleaned, the discharge tray 12 is pushed again by the first electric telescopic rod 7, and the discharge column 10 is separated from the discharge tray 12. The second electric telescopic rod 21 pulls the lower clamping assembly 9 through the upper clamping assembly 8. At this time, the connecting block 16 drives the gear 17 to move through the upper clamping assembly 8. The gear 17 rotates while moving and moves along the inside of the tooth plate 18, so that the upper clamping assembly 8 drives the lower clamping assembly 9 to return to its original position, completing the operation.

[0062] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
