[0002] At present, in many film industries, especially in the extrusion industry, materials are melted by the extruder and extruded through the die head before proceeding to the next step. Since some materials in the extruder barrel will deteriorate and carbonize during the heating process, these materials cannot be processed after extrusion, so the extruder will be operated first to extrude this part of the material, and the residue in the extrusion barrel will be cleaned by continuously extruding new molten materials.

[0003] This part of the squeezed waste accumulates and forms an accumulation, which is very difficult to handle after cooling. Most operators, in order to save trouble, will not deliberately clean it several times, which will cause large volume, irregular shape, and high hardness, which will bring great difficulties to recycling.

[0004] Therefore, in order to solve such problems, we propose an extrusion casting material processing device. Summary of the invention

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Reference Figure 1-6 , an extrusion casting material processing device, including a water bath 9, a material processing roller 1 is installed in the middle of the water bath 9, and cooling water can be installed inside the water bath 9. A power driving device for driving the material processing roller 1 is arranged on the side of the water bath 9, and a plurality of wedge-shaped racks 10 are arranged around the surface of the material processing roller 1. One end of the water bath 9 is matched with a water inlet valve 8, the bottom of the water bath 9 is matched with a drainage mechanism, and the other end of the water bath 9 is matched with a pressing roller 3 and a guide roller 4.

[0029] A die head 13 is provided on the top of the water bath 9. The die head 13 is arranged corresponding to the material processing roller 1. The die head 13 is used to flow down the molten material.

[0030] The water bath 9 is provided with a cavity structure matching the material processing roller 1, and the bottom of the cavity structure has an arc structure. There is a gap between the arc structure and the surface of the material processing roller 1 and can guide the preliminarily shaped material. The arc structure at the bottom of the water bath 9 is close to the material processing roller 1, and the overall structure facilitates the material processing roller 1 to drive the shaped material to move to the rear end.

[0031] The material handling roller 1 is open and hollow inside, and the material handling roller 1 can fully contact the cooling water in the water bath 9, which is convenient for faster heat dissipation. The several wedge-shaped racks 10 arranged on the surface of the material handling roller 1 can shape the molten material into a wedge-shaped shape, which is convenient for dragging and traction. It can also bring cooling water to the top of the material handling roller 1 like a waterwheel to flow down.

[0032] The power drive device includes a drive motor 7, which is fixedly arranged on the side of the water bath 9. Both ends of the material processing roller 1 are rotatably supported on the water bath 9 by a rotating shaft, and the connection between the rotating shaft and the water bath 9 is waterproofed. A drive wheel is installed on the driving side of the material processing roller 1, and a pulley 16 is coaxially installed on the drive motor 7. There is a certain reduction ratio between the drive wheel and the pulley 16. The drive wheel and the pulley 16 are connected by a belt 15, and the belt 15 is matched and arranged inside a protective cover shell 14.

[0033] The water inlet valve 8 is installed on one side of the top of the water bath 9, and the joint of the water inlet valve 8 extends to the outside of the water bath 9. The water inlet valve 8 is connected to the external water pipe for injecting water into the water bath 9. The water is cooling water for cooling the material. The drainage mechanism includes an overflow port 5 and a drain valve 6. The bottom of the water bath 9 is connected to a first drain pipe. The drain valve 6 is installed on the first drain pipe. The height of the overflow port 5 is higher than the height of the drain valve 6. The overflow port 5 is connected to the first drain pipe through a second drain pipe, and the connection of the second drain pipe is downstream of the drain valve 6. The second drainage is not controlled by the drain valve 6. When the water bath 9 is filled with water beyond the limit, it will overflow and discharge through the overflow port 5. Opening the drain valve 6 can replace the water in the water bath 9 as a whole.

[0034] According to the cooling and shaping effect of the material, the water inlet valve 8 can be opened normally to allow cooling water to be injected into the water bath 9, and then overflow from the overflow port 5, so that the water bath 9 can achieve the best cooling effect. The water inlet valve 8 can also be opened irregularly to replenish water to the water bath 9, and the best solution can be selected between the cooling and shaping effect of the material and water saving.

[0035] The pressure roller 3 and the guide roller 4 are arranged in parallel up and down, and a rectangular opening is provided on the top side of the water bath 9, and the pressure roller 3 and the guide roller 4 are arranged horizontally at the rectangular opening. A cylinder 2 for driving the pressure roller 3 to move up and down is vertically fixed on the top of the water bath 9, and a pneumatic handle 12 for controlling the cylinder 2 to perform pressing and disengaging operations is installed on the side of the water bath 9. The pressure roller 3 and the guide roller 4 do not have power themselves, and the existing winder must be used in the future to provide traction power, that is, the winder winds up the material. The pressure roller 3 can also be opened to press the material down for manual traction. The function of the pressure roller 3 and the guide roller 4 is, on the one hand, to flatten the material in the water bath 9, and on the other hand, to guide the material to leave the water bath 9. The action of the pressure roller 3 depends on the operation of the cylinder 2.

[0036] The material after passing through the water bath 9 and the material processing roller 1 is not necessarily completely cooled and shaped, and we do not need such an effect. As long as the material can be made into sheets for subsequent processing, the processed material is wound into a roll by a winder and cooled naturally.

[0037] A control panel 11 is installed on the side of the water bath 9. The control panel 11 can start and stop the drive motor 7. A frequency converter for adjusting the speed of the drive motor 7 is installed inside the control panel 11. The control panel 11 can control and adjust the frequency converter so that the material processing roller 1 reaches the optimal operating speed. The control panel 11 includes a start and stop button and an indicator light, which is convenient for operating the device and observing the status of the device. The water bath 9 is made of stainless steel as a whole and has a double-layer structure. The material processing roller 1 is also made of stainless steel. The control panel 11 on one side of the water bath 9 is detachable, and the interior is convenient for wiring and installation of various components.

[0038] During the working process: the die head 13 flows down the molten material, and the material handling roller 1 rotates continuously, flattens the molten material flowing down the die head 13 and cools it for preliminary shaping, and a number of wedge-shaped racks 10 make the material form a wedge-shaped structure, which is convenient for guiding and transmitting the material at the bottom of the arc-shaped structure of the water bath 9. After further cooling and shaping by the cooling water of the water bath 9, it is continuously transported to the subsequent processing device through the pressing roller 3 and the guide roller 4.

[0039] The rotation of the material handling roller 1 is driven by the driving motor 7, that is, the driving motor 7 drives the corresponding coaxial pulley 16 to rotate, and the pulley 16 drives the driving wheel to rotate through the belt 15, and finally drives the material handling roller 1 corresponding to the driving wheel to rotate. A frequency converter for adjusting the speed of the driving motor 7 is provided inside the control panel 11, and the control panel 11 can control and adjust the frequency converter so that the material handling roller 1 reaches the optimal operating speed.

[0040] In the above operation, according to the cooling and shaping effect of the material, the water inlet valve 8 can be kept open to allow cooling water to be injected into the water bath 9, and then overflow from the overflow port 5, so that the water bath 9 can achieve the best cooling effect. The water inlet valve 8 can also be opened from time to time to replenish water to the water bath 9, and the best solution can be selected between the cooling and shaping effect of the material and water saving. At the same time, a number of wedge-shaped racks 10 can not only shape the molten material into a wedge-shaped shape for easy dragging and traction, but also can bring the cooling water to the top of the material processing roller 1 like a waterwheel to flow down, so that the material processing roller 1 can dissipate heat faster and cool the material better. The overall structure is simple, can achieve the initial shaping of the material, and is convenient for the recovery and reprocessing of the material in the later stage, so as to achieve a better treatment effect on the cast material.

[0041] The above description is only a preferred specific implementation manner of the present invention, but 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 scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
