Description

Technical Field

[0001] This utility model relates to the field of modified plastics processing equipment, and in particular to an LFT-D granulation porous plate cleaning device. Background Technology

[0002] When recycling LFT materials, the LFT-D process demonstrates significant economic benefits and environmental characteristics. This process places particular emphasis on the resource utilization of waste generated during the production process and retired parts, with the aim of reducing resource waste and environmental pollution.

[0003] LFT-D recycled material is usually crushed into 6-10mm granules and then further processed for use. In order to improve the uniformity of addition and the accuracy of proportion mixing, LFT-D recycled material is usually granulated by twin-screw extrusion to achieve uniform particle formation.

[0004] In existing technologies, LFT-D components typically contain impurities after use and recycling. While metallic components can be removed using a magnetic separator, some non-magnetic metals, such as aluminum and copper, are difficult to remove completely. These impurities can cause breakage during granulation. Therefore, a screen is often used on a perforated plate during granulation to prevent large aluminum and copper particles from passing through and to mitigate breakage.

[0005] When the above operation is carried out, the perforated plate needs to be cleaned when the filter screen needs to be replaced. As the plastic in the holes of the perforated plate hardens and solidifies when the plate cools down, it is difficult to clean. Generally, a drill bit of the same diameter is needed to process each hole of the perforated plate to remove impurities. However, the method of using a drill bit to process the perforated plate has the following problems: (1) Since the perforated plate has a large number of holes, drilling each hole with a drill bit takes a long time; (2) It is difficult to control the verticality when drilling manually, which can damage the perforated plate and is unsafe; (3) The perforated plate needs to be reheated when cleaning the surface, which makes it difficult to clean thoroughly, resulting in low efficiency and making it difficult to install the filter screen.

[0006] Therefore, in view of the shortcomings of the existing technology, the technical problem that urgently needs to be solved by those skilled in the art is how to improve the technology and design a device that can quickly remove condensed materials in the orifice plate, so as to overcome or solve the above-mentioned technical problems in the existing technology. Utility Model Content

[0007] In view of the shortcomings of the prior art described above, this utility model proposes an LFT-D granulation perforated plate cleaning device, which can quickly and directly clean the material in the perforated plate by setting a vertically movable pressing device, and a heating device, pressing rod or pressing needle at the lower end of the pressing device.

[0008] The technical solution adopted by this utility model to solve its technical problem is:

[0009] A cleaning device for LFT-D granulation porous plates includes a base, a porous plate fixing device, a heating device, and a needle pressing device.

[0010] The base is provided with a vertical support, and the vertical support is provided with a vertical guide. The perforated plate fixing device is fixed on the base and includes a positioning groove, in which a support is provided. A pressure plate is provided in the vertical guide, a counterweight is fixed on the top of the pressure plate, and a needle pressing device is fixed on the bottom surface of the pressure plate. The needle pressing device includes several pressing needles. A heating device is provided inside the needle pressing device, and the wires and control components of the heating device extend to the outside.

[0011] The perforated plate fixing device includes two separate clamps that are connected and engaged. The base is provided with a longitudinal guide that engages with a vertical column. The two separate clamps are respectively connected to or pressed against the vertical column. At least one vertical column can drive the separate clamps to move longitudinally within the longitudinal guide to achieve clamping of the separate clamps.

[0012] A sensor is installed at the bottom of the perforated plate fixing device, and the sensor is used in conjunction with the needle pressure device. When the pressure needle or the pressed material reaches the sensor, the timing starts. The purpose of this design is to prevent the pressure needle from staying in the perforated plate for too long, which would cause energy waste and component deformation.

[0013] The pressure plate has a counterweight fixing groove on its top surface, and the counterweight is set in the counterweight fixing groove. The counterweight can move flexibly under external force.

[0014] A heat-insulating sealing layer is provided between the pressure plate and the needle pressing device to prevent the heat source from moving upward and affecting the placement and removal of the counterweight.

[0015] The heating device is an electric heating wire installed inside the needle pressing device, extending vertically into the interior of each pressing needle. The bottom of each pressing needle is tapered, a structure that facilitates the insertion of the pressing needle into the holes on the perforated plate.

[0016] The number of pressure needles is the same as the number of holes. The length and diameter of the pressure needles are determined according to the size design of the perforated plate. The length of the pressure needles is 20-50mm longer than the thickness of the perforated plate.

[0017] The heating device is equipped with a temperature control device, which includes a sensor and a temperature setting device. The sensor detects the temperature of the needle pressure device and realizes the temperature control of the needle pressure device. The temperature difference is controlled within ±10℃ to prevent the heating plate from heating continuously, which would cause overheating, safety issues, and wasted power.

[0018] This invention has the following advantages: A vertical support rod is provided on the base, and a vertical guide portion is provided on the vertical support rod; a perforated plate fixing device is fixed on the base, and a support portion is provided in the positioning groove above it; a pressure plate is provided in the vertical guide portion, a counterweight is fixed on the top of the pressure plate, and a needle pressing device is fixed on the bottom surface of the pressure plate, with several pressing needles and a heating device on the needle pressing device. This invention can drive the pressure plate and the needle pressing device to press down simultaneously with the help of the counterweight. Under high temperature, the pressing needles are gradually inserted into the material holes of the perforated plate to squeeze out the internal material. This invention is suitable for cleaning the perforated plate of LFT-D recycled material granulation. It allows for quick cleaning of the perforated plate, facilitating timely replacement of the perforated plate. It is simple to operate, safe and effective, highly practical, and suitable for widespread promotion. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described below through embodiments. The following description is merely an exemplary explanation. Those skilled in the art can make further structural improvements based on the following explanation. The scope of protection of this patent shall be determined by the scope set forth in the claims.

[0026] Example 1: An LFT-D granulation porous plate cleaning device, which includes a base 1, a porous plate fixing device 10, a heating device 7, and a needle pressing device;

[0027] like Figure 1 As shown, the base 1 is provided with a longitudinal guide groove 11, and a vertical rod 2 is provided in the longitudinal guide groove 11. The bottom of the vertical rod 2 is provided with a horizontal slider 22 that cooperates with the longitudinal guide groove 11. In this embodiment, there are two vertical rods 2, one of which is directly locked to the base 1, and the other is designed to be movable. The movable vertical rod 2 can move longitudinally in the longitudinal guide groove 11.

[0028] The vertical pole 2 is provided with a vertical guide groove 21 as a vertical guide part; a pressure plate 4 is provided in the vertical guide groove 21, and vertical sliders 41 are provided on the front and rear sides of the pressure plate 4 to match the vertical guide groove 21. The vertical sliders 41 cooperate with the vertical guide groove 21 to achieve vertical sliding. A counterweight fixing groove 42 is provided on the top of the pressure plate 4, and the counterweight 6 is fixed through the counterweight fixing groove 42. Those skilled in the art can also provide countersunk holes on the counterweight and threaded holes in the counterweight fixing groove 42 to lock and fix the counterweight 6 by bolt fixing. The counterweight 6 is also provided with a handle 61, and those skilled in the art can also replace the counterweight 6 through the handle 61.

[0029] A needle pressing device 5 is fixed on the bottom surface of the pressure plate 4. The needle pressing device 5 includes a plurality of pressing needles 51. A heating device 7 is provided inside the needle pressing device 5. In this embodiment, the heating device is an electric heating wire 75 disposed inside the needle pressing device 5. Figure 4 As shown, the heating wire 75 extends vertically into the interior of each pressure needle 51 via a wire 74. The bottom of the pressure needle 51 is tapered, which facilitates the insertion of the pressure needle 51 into the holes on the perforated plate 9. The wire 74 is connected to an external temperature sensor 73, and an external wire 72 extends from the temperature sensor 73 to connect to an external power source. The temperature sensor 73 is also connected to the controller 71 via a guide. The controller 71 and the temperature sensor 73 together form a temperature control device. The temperature of the pressure needle device 5 is detected by the temperature sensor 73 to control the temperature of the pressure needle device 5. The temperature difference is controlled within ±10℃ to prevent the heating device 7 from overheating, which would be unsafe and waste power.

[0030] The perforated plate fixing device 3 of this utility model includes two separate clamps 30 that fit together to form a groove for placing the perforated plate 9. Figure 1 , 3As shown, after the two separate clamps 30 are horizontally connected and fitted together, a positioning groove 31 is formed. A support part 32 is provided in the positioning groove 31. The support part 32 can be a raised step or a horizontal support point set inside. The two separate clamps 30 are vertically supported by the support part 32 to form a support unit.

[0031] The two separate clamps 30 provided on the base 1 are respectively connected to or pressed into contact with the vertical pole 2. Because at least one vertical pole 2 can drive the separate clamps 30 to move longitudinally within the longitudinal guide groove 11 to achieve clamping of the separate clamps 30, thereby achieving clamping of the perforated plate 9.

[0032] Further, such as Figure 1 , 3 As shown, a position sensor 10 is provided at the bottom of the perforated plate fixing device 3. The position sensor 10 is typically a mechanical pressure sensor or a touch sensor, and it works in conjunction with the pressure needle 51 on the needle pressing device 5. Timing starts when the pressure needle 51 or the pressed material reaches the position sensor 10. This design aims to prevent the pressure needle 51 from remaining in the perforated plate for too long, thus avoiding energy waste and component deformation.

[0033] Furthermore, since this utility model operates at high temperatures, in order to protect the pressure plate 4, a heat insulation sealing layer 8 is provided between the pressure plate 4 and the needle pressing device 5. The heat insulation sealing layer 8 prevents the heat source from moving upward and affecting the placement and removal of the counterweight 6.

[0034] Furthermore, the number of pressure needles 51 is the same as the number of holes. The length and diameter of the pressure needles 51 are determined according to the size design of the perforated plate 9. The length of the pressure needles 51 is 20-50mm longer than the thickness of the perforated plate.

[0035] The steps for using this utility model are as follows:

[0036] (1) Take the perforated plate 9 out of the extruder using a clamp, remove the screen stuck on the surface of the perforated plate, and clean the material on the surface and around the perforated plate using a scraper, etc. At this time, there is a large amount of material in the holes of the perforated plate 9.

[0037] (2) Turn on the heating device in advance and set the temperature to 230℃. The heater of the needle pressure device 5 will start working and the pressure needle 51 will start heating. Heat for 5-10 minutes. After the temperature sensor shows that the temperature has stabilized for 4 minutes, you can proceed to the next step.

[0038] (2) Place the perforated plate 9 in the perforated plate fixing device 3 with the screen facing upward. After adjusting the position, the movable part of the vertical pole 2 is fixed to the base plate 1 with screws to achieve the final fixing and positioning of the perforated plate 9.

[0039] (3) Place the counterweight 6 and the needle pressing device 5 in the vertical guide groove 21 to determine and stabilize their positions.

[0040] (4) The counterweight 6 is positioned and pressurized. At this time, with the cooperation of the needle pressing device 5 and the pressing block, the needle pressing device 5 moves downward, and the material in the hole of the perforated plate 9 is cleaned out from below until the top surface of the needle pressing device 5 is in close contact with the plate body of the perforated plate. At this time, the pressing needle 51 or the pressed material reaches the position sensor 10, and the position sensor 10 issues an alarm. At this time, the timing work can be started.

[0041] (5) After 2-5 minutes, the counterweight 6 can be removed and the needle pressure device 5 can be lifted to complete the cleaning of the perforated plate 9. If the other side needs to be cleaned, the above operation can be repeated.

[0042] This device cleans the perforated plate 9 without damaging its inner holes or body. Compared to using a hand drill, it is safer and more effective. The entire operation takes about 10 minutes, allowing for rapid replacement of the perforated plate. This device can quickly clean the perforated plate, facilitating timely replacement. It is simple to operate, safe, effective, highly practical, easy to manufacture, cost-saving, and highly functional.
