DETAILED DESCRIPTION
[0024] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.
[0025] As Figures 1-5 shown, a screening structure for polycarbonate production, the supporting table 1 is stably placed, the controller 2 is installed on the upper side of the supporting table 1 in advance, the operator can control each motor and other components through the controller 2, and the automatic operation process is controlled.
[0026] Then, looking at two sliding grooves 3, the sliding piece 4 inside the sliding groove 3 should be able to slide smoothly, which is well attached to the wall surface of the sliding groove 3, and can move freely on the guide rod 15. The guide rod 15 penetrates the sliding piece 4 to provide guidance for its movement, and the spring 16 on both sides is sleeved on the guide rod 15, one end of the spring 16 abuts against the inner wall of the sliding groove 3, and the other end abuts against the sliding piece 4, which plays a buffering and resetting role.
[0027] Start the driving part, motor two 13 runs, drives the cam 14 at the shaft end to rotate, because the arc block 18 on the guide frame 17 on one side of the sliding piece 4 abuts against one side of the cam 14, with the rotation of the cam 14, the arc block 18 will be pushed by the contour of the cam 14 to drive the sliding piece 4 to reciprocate along the sliding groove 3. In this way, the drying cylinder 5 installed on one side of the sliding piece 4 also reciprocates, which enhances the flowability of the material in the cylinder, and is beneficial to the subsequent screening operation,
[0028] The heat insulation ring 10 on one side of the drying cylinder 5 effectively blocks the heat dissipation, reduces the influence on the surrounding components, and at the same time reduces the energy consumption. At this time, the motor one 6 is started, the cross connection seat 7 at the shaft end of the motor one 6 drives the inserted screening cylinder 8 to rotate at high speed, and the polycarbonate material to be screened is poured into the opening above the drying cylinder 5,
[0029] The falling material is discharged through the discharge port 9 at the bottom end of the outer side of the drying cylinder 5, and the screening box 11 below the discharge port 9 preliminarily receives and secondarily screens the discharged material, further ensuring the screening accuracy, and the storage box 12 on the upper side of the support table 1 below the screening box 11 is used to collect the finally screened finished material. The storage box 12 is matched with the insertion slot 19 on one side of the support table 1 through the insertion strip 20 on one side, which is convenient for installation and disassembly, and is convenient for subsequent cleaning of the material in the storage box 12. In the whole polycarbonate production and screening process, all parts work together to efficiently complete the screening and drying task of the material.
[0030] The working principle of the embodiment is as follows:
[0031] The support table 1 is the basic bearing component of the whole screening device, and the controller 2 arranged on the upper side is used for centralized control of each power component, and provides an instruction output port for realizing automatic operation.
[0032] The two sliding grooves 3 and the sliding piece 4 constitute a moving track system of the drying cylinder 5. The guide rod 15 penetrates through the sliding piece 4, ensuring that the sliding piece 4 can only move linearly in a specific direction in the sliding groove 3, and the two side springs 16 play a key buffering and resetting function. When the driving part is working, the motor 13 drives the cam 14 to rotate. Since the arc block 18 on the one side of the sliding piece 4 is always in close contact with the cam 14, and with the periodic change of the contour of the cam 14, the arc block 18 is subjected to different direction thrust, thereby driving the sliding piece 4 to reciprocate in the sliding groove 3. In this way, the drying cylinder 5 installed on the sliding piece 4 also synchronously reciprocates, and this movement mode can make the polycarbonate material in the cylinder be in dynamic change at all times, effectively avoiding material accumulation and caking, greatly enhancing the flowability of the material, and creating good conditions for subsequent accurate screening.
[0033] In the screening core link, the rotary screening assembly plays a key role. After the motor 6 is started, the cross connection seat 7 at the shaft end drives the inserted screening cylinder 8 to rotate at high speed. The polycarbonate material put into the drying cylinder 5 is subjected to multiple actions such as centrifugal force, collision and friction with the cylinder wall, and the smaller size material can pass through the screen hole on the wall of the screening cylinder 8, realizing preliminary screening, and the larger particle material that does not pass through the screen hole continues to be in the screening cylinder 8 to receive further tumbling and screening.
[0034] The heat insulation ring 10 on one side of the drying cylinder 5 uses the heat insulation material characteristics to effectively isolate the inside of the drying cylinder 5 from the external environment. On the one hand, it prevents the heat generated by drying from being dissipated to the surrounding air, causing energy waste; on the other hand, it avoids heat damage to the surrounding components such as the sliding groove 3 and the sliding piece 4, ensuring the stable operation of the entire screening structure.
[0035] After being screened by the screening cylinder 8, the material is discharged through the discharge port 9 at the bottom end of the outside of the drying cylinder 5. At this time, the screening box 11 located below the discharge port 9 again receives and screens the discharged material, and further improves the screening accuracy by using the specially designed screen or structure to further intercept the fine unqualified particles that may be mixed in the screened material.
[0036] Finally, the qualified polycarbonate finished product material after double screening falls into the storage box 12 on the upper side of the support table 1 below the screening box 11. The storage box 12 is conveniently inserted through the insertion strip 20 on one side and the insertion slot 19 on one side of the support table 1, facilitating quick disassembly and cleaning after the material is collected, so as to ensure the continuity of the entire production process. The components of the entire screening structure are closely matched, and through the cooperation of mechanical movement, screening principle and heat management, the screening task of the polycarbonate material is efficiently completed.
[0037] It should be noted that the drying cylinder 5 is embedded with heating wires.
[0038] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
