Description

Technical Field

[0001] The invention relates to the technical field of plastic processing, and more particularly to a hot cutting component of polyethylene hot cutting granulation equipment. Background Art

[0002] Hot cutting granulation of polyethylene is a common plastic processing technology, which is used to make polyethylene from a molten state into small particles for subsequent processing. The basic process of hot cutting granulation of polyethylene includes five steps: raw material preparation, melt extrusion, cooling, hot cutting and particle collection.

[0003] The working process of the existing polyethylene hot cutting granulation equipment is as follows: the raw materials are put into the extruder. Under the processing conditions of the extruder, the raw materials will first be heated to a molten state, and then extruded from the extruder through the extruder head to form continuous molten strips. Then, under the action of the conveyor roller, the molten strips are transported through a cooling water tank so that the molten strips are quickly cooled and solidified. After cooling, the solidified polyethylene strips are cut by a hot cutting machine. Finally, the cut small particles are collected by air or gravity into a collector to form polyethylene particles.

[0004] When the polyethylene molten strips pass through the cooling water tank and are sent out by the conveyor roller, the polyethylene strips often need to enter the dryer to dry their surface to ensure that the moisture content in the raw materials is not too high and that no bubbles are generated on the surface of the polyethylene strips during the drying process of the dryer, so as to improve the production quality of polyethylene. However, when polyethylene is in the dryer, it is necessary to always control the environment in the dryer and various values ​​within the standard range, which consumes a lot of energy. In addition, the moisture dried on the surface of the polyethylene strips will become gaseous in the dryer. As the fan in the dryer blows out of the dryer, this part of the moisture will remain in the air, which is not convenient for recycling, thus resulting in a waste of resources and increased cost consumption.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0031] See also Figures 1 to 8A hot cutting component of a polyethylene hot cutting granulation equipment comprises a conveyor belt body 1, a polyethylene strip body 2 is arranged on the conveyor belt body 1, a recycling box 3 is fixedly installed on the conveyor belt body 1, a material receiving box 9 is fixedly installed at the end of the conveyor belt body 1, the recycling box 3 is used to clean the moisture on the surface of the polyethylene strip body 2, a cutting frame 4 is fixedly installed on the end of the conveyor belt body 1 away from the recycling box 3, an electric telescopic rod 5 is fixedly installed inside the cutting frame 4, a base 6 is slidingly arranged inside the cutting frame 4, and the base 6 is fixedly connected to the telescopic end of the electric telescopic rod 5, the bottom of the base 6 is fixedly connected to a cutting blade mounting seat 7, a cutting blade body 8 is fixedly installed on the cutting blade mounting seat 7, a recycling chamber 10 is opened inside the recycling box 3, a water absorption block 11 is fixedly installed at one end of the recycling chamber 10 away from the material receiving box 9, and the water absorption block 11 contacts the outer surface of the polyethylene strip body 2.

[0032] The water absorbing block 11 is made of porous ceramic material and is arranged in a bucket shape. The inner wall of the front end of the water absorbing block 11 contacts the outer surface of the polyethylene strip body 2 , and the rear end of the water absorbing block 11 is completely located in the recovery chamber 10 .

[0033] The polyethylene strip body 2 cooled by the cooling water tank is transported to the inside of the recycling box 3 as the conveyor belt body 1 works. When the polyethylene strip body 2 enters the recycling box 3 and contacts the water absorption block 11, the water absorption block 11 absorbs the moisture on the surface of the polyethylene strip body 2. Then the conveyor belt body 1 transports the polyethylene strip body 2 with the surface moisture absorbed to the bottom of the cutting frame 4. The electric telescopic rod 5 inside the cutting frame 4 works to move the cutting frame 8 downward, cutting the polyethylene strip body 2 into granules and then dropping them into the receiving box 9, completing the hot cutting of the polyethylene strip body 2. The water absorption block 11 can be used to remove the residual water on the surface of the polyethylene strip body 2, thereby preventing the water content on the surface of the polyethylene strip body 2 from being too high. In the process of the heated cutter cutting the surface of the polyethylene strip body 2, a large amount of water vapor will evaporate due to the high temperature and mix in the polyethylene strip body 2, causing bubbles to form on its surface, thus affecting the quality of the particles. There is no need to use a dryer in the existing equipment, and the water absorbed by the water absorption block 11 will remain in the water absorption block 11, which is convenient for the subsequent collection of water in the water absorption block 11, greatly saving energy consumption and reducing production costs.

[0034] like Figures 1 to 3As shown, the recovery chamber 10 is used to contact the inner wall of the polyethylene strip body 2 and is provided with a drying groove 12, the drying groove 12 penetrates the inner wall of the recovery chamber 10, a circle of heating plates 13 are fixedly installed on the inner wall of the recovery chamber 10, a first ring frame 14 is fixedly installed at one end of the recovery box 3, the first ring frame 14 is connected with the recovery chamber 10, a second ring frame 15 is fixedly installed at one end of the recovery box 3, and the second ring frame 15 is located above the first ring frame 14, a connecting pipe 16 is fixedly inserted on the first ring frame 14, and the first ring frame 14 and the second ring frame 15 are connected through the connecting pipe 16, a circulation pipe 17 is fixedly inserted at one end of the connecting pipe 16, an air pump 18 is fixedly installed inside the circulation pipe 17, and the circulation pipe 17 is connected with the second ring frame 15.

[0035] The one-way valve 26 is used in conjunction with the air pump 18 . The one-way valve 26 allows the gas in the circulation tube 17 to flow in the direction from the air pump 18 to the one-way valve 26 . The air pump 18 is used to suck the gas in the recovery chamber 10 into the circulation tube 17 .

[0036] A first pipeline 19 communicating with the inside of the circulation pipe 17 is opened on the circulation pipe 17, and two groups of first pipelines 19 are symmetrically arranged on the left and right. A second pipeline 20 communicating with the inside of the circulation pipe 17 is opened on the circulation pipe 17, and two groups of air nozzle bodies 21 are fixedly installed on the inner wall of the cutter frame 4, and the air nozzle bodies 21 are symmetrically arranged on the left and right. Each group of first pipelines 19 is connected to the air nozzle body 21, and the air nozzle body 21 can heat the outer surface of the cutter body 8. A heating chamber 22 is opened inside the cutter body 8, and the second pipeline 20 passes through the base 6 and the cutter body 8 from the top of the base 6 and is connected to the heating chamber 22.

[0037] After the moisture on the surface of the polyethylene strip body 2 is absorbed by the water absorbing block 11, the air pump 18 and the heating plate 13 start to work, and the external air is sucked into the recovery chamber 10 through the water absorbing block 11. Since the water absorbing block 11 is made of porous ceramic material, it can effectively absorb moisture and has good moisture migration ability in its pores, so it is convenient to use the air pump 18 to bring out the moisture in the water absorbing block 11 through the air. The moisture brought into the recovery chamber 10 by the air will absorb high heat and be converted into high-temperature water vapor under the action of the heating plate 13, and then adhere to the air and enter the first ring frame 14, and enter the second ring frame 15 and the circulation pipe 17 through the connecting pipe 16, and a part of it The air containing high-temperature water vapor enters the air nozzle body 21 through the first pipeline 19 to heat the outer surface of the cutter body 8, and another part of the air containing high-temperature water vapor enters the heating chamber 22 of the cutter body 8 through the second pipeline 20 to heat the inside of the cutter body 8. The inside and outside of the cutter body 8 are heated at the same time, thereby accelerating the heating speed of the cutter body 8 and reducing the situation in which the cut polyethylene thin strip body 2 is not formed when the cutter body 8 is not fully heated, and too much waste is required, thereby increasing the production cost. The medium for heating the cutter here is the water vapor absorbed in the water absorbent block 11, which further reduces the cost and saves energy.

[0038] If there is too much water on the surface of the polyethylene strip body 2 and the water absorbing block 11 cannot completely absorb it, the remaining water on the surface of the polyethylene strip body 2 will be dried and taken away by the high-temperature gas flowing in the recovery chamber 10 during the process of passing through the drying tank 12;

[0039] It should be noted here that: the heating medium is water vapor. Since the temperature of water vapor at room temperature is lower than one hundred degrees Celsius, and the melting temperature of the polyethylene strip body 2 is usually between 180°C and 230°C, when water vapor is used to heat the cutter body 8, there is no need to consider the maximum heating temperature, thereby reducing the conditions that need to be controlled in the production of polyethylene particles.

[0040] like Figures 6 to 8 As shown, two groups of scrapers 31 symmetrical to each other are fixedly mounted on the inner wall of the cutter frame 4 . The scrapers 31 are made of hard rubber material and are pressed against the surface of the cutter body 8 .

[0041] Each time the cutter body 8 cuts the polyethylene strip body 2 up and down, the cutter body 8 will move up and down relative to the fixed scraper 31. When the cutter body 8 moves upward relative to the scraper 31, the debris sticking to the surface of the cutter body 8 due to cutting the polyethylene strip body 2 will be scraped off by the scraper 31, thereby reducing the debris sticking to the surface of the cutter body 8 when the cutter body 8 cuts the polyethylene strip body 2, and reducing the quality of the produced polyethylene particles.

[0042] like Figures 4 to 8 As shown, the internal sliding seal of the circulation tube 17 is provided with a stamping plate 25, on which a one-way valve 26 is fixedly installed, and the one-way valve 26 allows gas to pass through the stamping plate 25. A sliding rod 28 is fixedly sleeved on the stamping plate 25. The inner wall of the circulation tube 17 is fixedly connected to a ring 27, and the sliding rod 28 is slidably sleeved on the outer surface of the ring 27. The outer surface of the sliding rod 28 is sleeved with a tension spring 29, one end of the tension spring 29 is fixedly connected to the ring 27, and the other end of the tension spring 29 is fixedly connected to the stamping plate 25. The jetting direction of the nozzle body 21 faces the bottom of the scraper 31.

[0043] The outer wall of the telescopic end of the electric telescopic rod 5 is in the same horizontal plane as the outer wall of the base 6, the base 6 and the cutter mounting seat 7 are integrally connected, and the thickness of the base 6 and the cutter mounting seat 7 gradually decreases from top to bottom. The telescopic end of the electric telescopic rod 5, the base 6 and the cutter mounting seat 7 can limit the sliding rod 28.

[0044] The aperture of the first pipe opening 23 is smaller than the thickness of the stamping plate 25, and the second pipe opening 24 is always in an open state when the cutter body 8 is working.

[0045] When the air pump 18 draws the high temperature water vapor in the recovery chamber 10 into the flow pipe 17, it will enter the chamber 10 through the one-way valve 26 on the stamping plate 25. Figure 6 As shown in the figure, on the left side of the stamping plate 25, after the cutter body 8 starts to cut the polyethylene strip body 2, the electric telescopic rod 5 extends to continue cutting the polyethylene strip body 2. Since the outer wall of the telescopic end of the electric telescopic rod 5 and the outer wall of the base 6 are in the same horizontal plane, the base 6 and the cutter mounting seat 7 are connected as a whole, and the thickness of the base 6 and the cutter mounting seat 7 gradually decreases from top to bottom, the telescopic end of the electric telescopic rod 5, the base 6 and the cutter mounting seat 7 can limit the slide bar 28. At this time, the slide bar 28 is limited by the telescopic end of the electric telescopic rod 5, the base 6 and the cutter mounting seat 7, and the slide bar 28 will be as shown in the figure. Figure 6 As shown in FIG. 1 , the first pipe 22 moves to the right, thereby stretching the tension spring 29, and then the stamping plate 25 blocks the first pipe opening 23. At this time, the first pipe 19 stops heating the outer surface of the cutter body 8, and only the second pipe 20 rushes high-temperature water vapor into the heating chamber 22 to keep the temperature inside the cutter body 8 constant;

[0046] When the cutter body 8 cuts the polyethylene strip body 2 and needs to move upward, the telescopic end of the electric telescopic rod 5 is retracted, and the slide bar 28 is not limited by the telescopic end of the electric telescopic rod 5, the base 6 and the cutter mounting seat 7. Under the action of the stretched tension spring 29, the slide bar 28 will carry the stamping plate 25 as shown in FIG. Figure 6As shown, the cutter body 8 moves to the left, and the stamping plate 25 no longer blocks the first nozzle 23. During the upward movement of the cutter body 8, the first nozzle 23 is gradually opened to heat the outer surface of the cutter body 8, thereby reducing the situation in which the temperature inside the cutter body 8 is higher than the temperature outside the cutter body 8 due to the fact that the cutter body 8 no longer performs a cutting action, resulting in no heat generation and the surface temperature drops, resulting in the occurrence of water droplets;

[0047] It should be noted that when the cutter body 8 cuts the polyethylene strip body 2, the outer surface of the cutter body 8 will heat up due to friction. Since the cutting speed of the cutter body 8 is fast, the surface temperature of the cutter body 8 rises more significantly. Obviously, the heat inside the cutter body 8 needs to be balanced to reduce the water droplets generated on the cutter surface due to the temperature difference. Therefore, the heat generated here can be used to stop heating the outer surface of the cutter.

[0048] When the machine is just started to preheat the cutter body 8, since the slide bar 28 is not limited by the electric telescopic rod 5, the base 6 and the cutter mounting seat 7, the first pipe opening 23 and the second pipe opening 24 are both opened, and the inside and outside of the cutter are heated at the same time, so that the cutter heats up quickly, and the device has a higher degree of automation.

[0049] like Figures 6 to 8 As shown, a pressure stabilizing groove 30 is provided on the cutter body 8, and the pressure stabilizing groove 30 is communicated with the heating chamber 22, and the pressure stabilizing groove 30 extends from the inside to the outside and is inclined downward by more than 45 degrees.

[0050] During the preheating process of the cutter body 8, according to actual production, it is still necessary to cut the polyethylene strip body 2. In order to reduce the situation where the polyethylene material debris sticks to the cutter body 8, high-temperature water vapor is always passed into the heating chamber 22. The high-temperature water vapor entering the heating chamber 22 will be sprayed out through the pressure-stabilizing groove 30. Since the pressure-stabilizing groove 30 extends from the inside to the outside and is tilted downward by more than 45 degrees, the high-temperature water vapor sprayed through the pressure-stabilizing groove 30 will be sprayed onto the outer surface of the cutter body 8, and then the polyethylene material debris sticking to the surface of the cutter body 8 will be blown away, reducing the polyethylene material debris sticking to the surface of the cut polyethylene particles, thereby affecting the staff's judgment on whether the cutter body 8 is preheated, which provides convenience for the staff when checking the preheating of the cutter.

[0051] Usage: After being cooled in the cooling water tank, the polyethylene strip body 2 is transported to the inside of the recycling box 3 as the conveyor belt body 1 works. When the polyethylene strip body 2 enters the recycling box 3 and contacts the water absorption block 11, the water absorption block 11 will absorb the moisture on the surface of the polyethylene strip body 2. Then the conveyor belt body 1 transports the polyethylene strip body 2 with the surface moisture absorbed to the bottom of the cutting frame 4. The electric telescopic rod 5 inside the cutting frame 4 works to move the cutting frame 8 downward, cutting the polyethylene strip body 2 into granules and then dropping them into the receiving box 9, completing the hot cutting of the polyethylene strip body 2. The operation of removing residual water from the surface of the polyethylene strip body 2 can be completed through the water absorption block 11, so as to avoid excessive water content on the surface of the polyethylene strip body 2. When the heated cutter is cutting the surface of the polyethylene strip body 2, a large amount of water vapor will evaporate due to the high temperature and mix in the polyethylene strip body 2, so that bubbles will be generated on the surface, affecting the quality of the particles. There is no need to use a dryer in the existing equipment, and the water absorbed by the water absorption block 11 will remain in the water absorption block 11, which is convenient for the subsequent collection of water in the water absorption block 11, greatly saving energy consumption and reducing production costs.

[0052] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
