Description

Technical Field

[0001] The invention belongs to the technical field of plastic molding processing, in particular to a material discharging processing device for a PVC film calender. Background Art

[0002] PVC film is a plastic film, the main component of which is polyvinyl chloride, and other ingredients may be added to enhance its heat resistance, toughness and ductility. The top layer of this surface film is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive.

[0003] A patent application with publication number CN115625837A discloses a discharge processing machine for PVC film calendering, including a casing, a top cover is arranged on the top of the casing, a feed pipe is fixedly installed on the outer wall of one side of the casing, and a plastic storage mechanism is fixedly installed on the outer wall of the other side of the casing. By arranging a clearing component inside, feed blockage can be effectively avoided.

[0004] When the above-mentioned prior art is in use, impurities in the raw materials are screened through the filter plate.

[0018] 1. In the material discharging processing device for a PVC film calender described in the present invention, a rotating rod drives a scraper to rotate, and raw materials can fall between the scrapers in equal amounts. The scraper rotates and drives the raw materials to fall on the filter plate. The raw materials and impurities are screened by the filter plate, so that the raw materials can flow to the surface of the corona mechanism in equal amounts and at a uniform flow rate, which can improve the corona treatment effect of the raw materials. At the same time, the scraper can also clean the impurities on the surface of the filter plate.

The push plate can push the raw material to move. The raw material is pushed by the push plate so that the raw material can pass through the filter plate quickly, which can avoid the viscosity of the raw material liquid being too high, thereby increasing the filtration time, thereby causing the problem that the raw material liquid is not completely filtered and is discharged from the slag discharge port.

[0020] 3. The present invention relates to a discharge processing device for a PVC film calender. When the moving rod moves from the reset section to the push section, the moving rod drives the piston to slide downward, and the piston sends the cooling airflow inside the first pump tube to the heat exchange plate. The heat exchange plate can cool the surface of the fixed frame, and then send it into the heat exchange tube through the heat exchange plate. The heat exchange tube can cool the surface of the push plate. When the raw material falls on the upper surface of the push plate, the raw material can be cooled to reduce the temperature of the raw material. Lowering the temperature can make the molecules or particles of the raw material liquid easier to flow, thereby reducing its viscosity. The reduced viscosity of the raw material can make it more convenient to pass through the filter plate, while avoiding the problem that the excessive temperature of the raw material may cause difficulties in calendering and molding, which will affect the quality and performance of the product.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0031] like Figures 1 to 4 As shown, a material discharging processing device for a PVC film calender according to an embodiment of the present invention comprises a shell 1, a feed pipe 11 is fixedly connected to the upper surface of the shell 1, a filter plate 13 is fixedly connected to the lower surface of the shell 1, a discharge pipe 12 is fixedly connected to the lower surface of the filter plate 13, a slag discharge port 14 is arranged on one side of the shell 1, a rotating rod 2 is fixedly connected to the inside of the shell 1, a plurality of scrapers 21 are fixedly connected to the surface of the rotating rod 2, a pushing mechanism is arranged inside the rotating rod 2, and the pushing mechanism is used to push the raw material to quickly pass through the filter plate 13 for screening operation, and the pushing mechanism is used to push the raw material to pass through the filter plate 13 for screening operation. The mechanism includes a fixed rod 26 rotatably arranged inside the rotating rod 2, and both ends of the fixed rod 26 are fixedly connected to the two ends of the outer shell 1, and a limiting roller 27 is fixedly connected to the surface of the fixed rod 26, and both ends of the limiting roller 27 are provided with a limiting groove 28, and a plurality of moving rods 24 are slidably connected inside the limiting groove 28, and the moving rod 24 is slidably connected to the inside of the rotating rod 2, and one end of the moving rod 24 is fixedly connected to a moving plate 29, and a push plate 4 is symmetrically slidably arranged on the side of the moving plate 29 away from the moving rod 24, and one end of each of the push plates 4 is in contact with one side of the scraper 21.

[0032] In the prior art, the plastic raw material needs to be filtered through the filter plate 13 before corona discharge to filter the impurities on its surface. The impurities in the raw material may block the filter holes of the filter plate 13 and affect the normal discharge of the raw material. At the same time, when the viscosity of the raw material is too high, the friction between the raw material and the filter plate 13 increases, increasing the resistance of the discharge, which may cause the raw material liquid to flow slowly, resulting in the problem that the raw material liquid is not completely filtered and is discharged from the slag discharge port 14;

[0033] The use process of the device is as follows: the raw material passes through the inside of the feed pipe 11, and the rotating rod 2 is driven to rotate at the same time. The rotating rod 2 drives the scraper 21 to rotate, so that the raw material can fall on the push plate 4 between the scrapers 21. The rotating rod 2 drives the scraper 21 to rotate to the discharge pipe 12. At this time, the raw material falls on the filter plate 13 by gravity, and the impurities in the raw material are filtered by the filter plate 13. At the same time, when the rotating rod 2 rotates, it will drive the moving rod 24 to rotate synchronously. The moving rod 24 slides in the limit groove 28. When it rotates to the filter plate 13, the moving rod 24 is squeezed by the limit groove 28, so that the moving rod 24 slides downward, and the moving rod 24 drives The movable plate 29 moves downward, and the movable plate 29 drives the push plate 4 to slide downward. One end of the two push plates 4 is in contact with one side between the scrapers 21, so that the push plate 4 can push the raw material downward. The raw material is pushed by the push plate 4 and can quickly pass through the filter plate 13 and fall into the discharge pipe 12. Then the rotating rod 2 continues to drive the scraper 21 to rotate. The subsequent group of scrapers 21 can push the impurities filtered on the filter plate 13 and push the impurities to the slag discharge port 14. The impurities are automatically discharged through the slag discharge port 14. At this time, the movable rod 24 is limited by the limit groove 28, and drives the movable plate 29 and the push plate 4 to perform a reset operation;

[0034] The device conveys raw materials through a plurality of scrapers 21, so that the raw materials can flow to the surface of the corona mechanism in equal amounts and at a uniform flow rate, which can improve the corona treatment effect of the raw materials. At the same time, the scraper 21 can also clean the impurities on the surface of the filter plate 13, so that the impurities are automatically discharged, avoiding the problem that the impurities block the filter plate 13 and cause the subsequent raw materials cannot be discharged normally. In addition, the push plate 4 cooperates with the movable plate 29 to quickly push the raw materials out, avoiding the problem that the raw material viscosity is too high, causing the raw material liquid to flow slowly on the surface of the filter plate 13, resulting in the raw material liquid not being completely filtered and being discharged from the slag discharge port 14 and reducing the discharge efficiency.

[0035] like Figure 1 and Figure 3 As shown, both ends of the housing 1 are fixedly connected to a support frame 53, both ends of the fixed rod 26 are rotatably connected to the inside of the support frame 53, one end of the rotating rod 2 is fixedly connected to a worm gear 52, one side of the support frame 53 is fixedly connected to a motor 5, the output end of the motor 5 is fixedly connected to a worm 51, and the worm gear 52 and the worm 51 are meshed with each other.

[0036] Specifically, the driving motor 5 is turned on, and the motor 5 drives the worm 51 to rotate. The worm 51 can engage with the worm wheel 52, so that the worm wheel 52 can drive the rotating rod 2 to rotate. At the same time, the worm 51 and the worm wheel 52 have a self-locking feature, which can prevent the rotating rod 2 from reversing, causing the scraper 21 to reverse the feeding, resulting in a large amount of raw materials being discharged through the slag discharge port 14.

[0037] like Figure 2 As shown, the end of the scraper 21 away from the rotating rod 2 can fit the inner wall of 1, the end of the scraper 21 away from the rotating rod 2 can fit the inner wall of 13, and one end of the slag discharge port 14 is inclined.

[0038] Specifically, the scraper 21 fits against the inner wall of the outer shell 1 to form a sealing area, which can ensure equal transportation of raw materials. At the same time, the scraper 21 fits against the inner wall of the filter plate 13, which can clean the impurities retained on the inner wall of the filter plate 13. The impurities can automatically slide down through the inclined surface of the slag discharge port 14.

[0039] like Figure 6 As shown, one side of the fixed frame 36 is fixedly connected to a limiting rod 6, the interior of the push plate 4 is slidably connected to the surface of the limiting rod 6, the interior of the limiting rod 6 is slidably connected to a sliding rod 61, one end of the sliding rod 61 is fixedly connected to the interior of the push plate 4, and a second spring 62 is fixedly connected between one end of the sliding rod 61 and the inner wall of the limiting rod 6.

[0040] Specifically, the second spring 62 can ensure that the push plate 4 and one side of the scraper 21 remain in contact with each other. At this time, the second spring 62 is in a compressed state. When the movable plate 29 drives the push plate 4 to move, the distance between the scrapers 21 increases. At this time, the push plate 4 drives the slide bar 61 to slide inside the limit rod 6. The compression of the second spring 62 is released, which can drive the slide bar 61 to slide inside the limit rod 6, thereby increasing the convenience of the push plate 4 to push the raw materials through the filter plate 13. Embodiment 2

[0041] like Figure 7 As shown in Comparative Example 1, another embodiment of the present invention is:

[0042] The push plate 4 has a heat exchange tube 39 fixedly connected inside, the fixing frame 36 has a heat exchange plate 37 fixedly connected inside, the lower surface of the heat exchange plate 37 has a first exhaust pipe 311 fixedly connected, and the first exhaust pipe 311 is not connected to the heat exchange plate 37, one end of the first exhaust pipe 311 is fixedly connected to a connecting pipe 310, and both ends of the heat exchange tube 39 are fixedly connected to the lower surface of the heat exchange plate 37 and one end of the connecting pipe 310 with a telescopic hose 38.

[0043] Specifically, when the raw materials are fed, their temperature is relatively high, the movement speed of molecules or atoms will increase, and the viscosity between the raw materials will increase. When the viscosity of the raw materials is greater than the spring force between the push plate 4 and the fixed frame 36, the push plate 4 and the fixed frame 36 may be adhered by the raw materials. When the push plate 4 descends to extrude the raw materials, the push plate 4 may not be able to unfold and fit the inner wall of the scraper 21, thereby failing to extrude and discharge the raw materials. At the same time, the excessively high temperature of the raw materials may lead to difficulties in calendering and molding, thereby affecting the quality and performance of the product.

[0044] The use process of the device is as follows: when the raw material falls on the push plate 4 and the upper surface of the fixed frame 36, the heat of the raw material is absorbed by the push plate 4 and the fixed frame 36, and then the heat of the fixed frame 36 is transferred to the surface of the heat exchange plate 37 and the fixed frame 36 is heat exchanged. The heat on the surface of the push plate 4 is transferred to the surface of the heat exchange tube 39 and the push plate 4 is heat exchanged, so that the push plate 4 and the fixed frame 36 can reduce the temperature of the raw material. When the push plate 4 slides, the heat exchange tube 39 can ensure the communication relationship with the heat exchange plate 37 by stretching the telescopic hose 38. The heat exchange tube 39 is serpentinely distributed, which can maximize the heat exchange treatment with the push plate 4;

[0045] The temperature of the raw material can be reduced by heat exchange. Cooling can make the molecules or particles of the raw material liquid flow more easily, thereby reducing the viscosity of the raw material liquid. Therefore, it can be avoided that when the viscosity of the raw material is greater than the spring force between the push plate 4 and the fixed frame 36, the push plate 4 and the fixed frame 36 may be adhered to the raw material. When the push plate 4 squeezes the raw material to go down, the push plate 4 may not be able to unfold and fit with the inner wall of the scraper 21, thereby failing to squeeze and discharge the raw material. In addition, reducing its viscosity makes it more convenient to pass through the filter plate 13. At the same time, it can also avoid the problem that the raw material temperature is too high, which may cause calendering and molding difficulties and affect the quality and performance of the product.

[0046] like Figures 4 to 7 As shown, one end of the rotating rod 2 is fixedly connected to the first pump pipe 22, and the interior of the first pump pipe 22 is slidably connected to the piston 34, and the interior of the piston 34 is fixedly connected to the surface of the moving rod 24, and one end of the fixed rod 26 is rotatably connected to the air intake sleeve 3, and the surface of the air intake sleeve 3 is fixedly connected to the air intake check valve 32, and one end of the air intake check valve 32 is fixedly connected to the surface of the first pump pipe 22, and an exhaust check valve 33 is arranged at one end of the first pump pipe 22, and an air intake pipe is fixedly connected between one end of the exhaust check valve 33 and the interior of the heat exchange plate 37, and the other end of the rotating rod 2 is fixedly connected to the second pump pipe 23, and one end of the second pump pipe 23 is fixedly connected to one end of the first exhaust pipe 311. The other end of the rod 26 is rotatably connected to an exhaust sleeve 313, and a second exhaust pipe 312 is fixedly connected between the exhaust sleeve 313 and the surface of the second pump pipe 23. The limiting groove 28 includes a reset section 281 and a push-out section 282. One end of the movable rod 24 is rotatably connected to a movable wheel 25, and the surface of the movable wheel 25 is slidably connected to the inside of the limiting groove 28. The outer wall of the fixed rod 26 is symmetrically provided with a plurality of air inlet holes 31, and the positions of the exhaust sleeve 313 and the air inlet sleeve 3 are respectively located on the outside of the air inlet holes 31. The surface of the movable rod 24 is fixedly connected to a cross plate 314, and the upper surface of the cross plate 314 is fixedly connected to a first spring 35, and the surface of the cross plate 314 is fixedly connected to the inner wall of the piston 34.

[0047] Specifically, when the scraper 21 and the push plate 4 are conveying the raw materials, the moving rod 24 is in the reset section 281, and at the same time, the heat exchange tube 39 performs heat exchange treatment on the push plate 4, and the heat exchange plate 37 performs heat exchange treatment on the fixed frame 36. The scraper 21 drives the raw materials to rotate, so that the contact position of the raw materials between the scraper 21 and the fixed frame 36 and the push plate 4 changes, thereby improving the heat exchange efficiency of the raw materials. At this time, the first spring 35 is in a stretched state. When the moving rod 24 drives the moving wheel 25 to move to the push-out section 282, the moving rod 24 drives the moving plate 29 to slide downward, so that the moving rod 24 drives the cross plate 314 and the piston 34 to slide inside the first pump pipe 22, so that the cross plate 314 squeezes the first spring 35, and the piston 34 sends the cold air flow inside the first pump pipe 22 into the inside of the heat exchange plate 37 through the exhaust one-way valve 33, and then sends it into the inside of the heat exchange tube 39 through the telescopic hose 38, so that the cooling air can cool the heat exchange plate 37 and the heat exchange tube 39.

[0048] The hot air inside the heat exchange plate 37 and the heat exchange tube 39 is blown to the connecting tube 310 by the cold air, enters the second exhaust pipe 312 through the connecting tube 310, enters the second pump pipe 23 through the second exhaust pipe 312, and then enters the second exhaust pipe 312 through the second pump pipe 23, and finally enters the exhaust sleeve 313 through the second exhaust pipe 312. The hot air in the exhaust sleeve 313 enters the fixed rod 26 through the air inlet 31 and is discharged from one end of the fixed rod 26.

[0049] When the moving rod 24 enters the reset section 281 from the push section 282, the moving rod 24 is driven to reset by the first spring 35, and the moving rod 24 drives the piston 34 to reset, and the piston 34 moves upward and opens the air intake check valve 32, so that the fixed rod 26 is connected to the end of the cold source to take in air, and the cold air enters the air intake sleeve 3 through the air intake hole 31, and then enters the air intake check valve 32 from the air intake sleeve 3, and enters the first pump pipe 22 through the air intake check valve 32 for storage, and the operation is repeated to achieve the temperature reduction treatment of the raw material;

[0050] The temperature of the raw material can be lowered. Lowering the temperature can make the molecules or particles of the raw material liquid flow more easily, thereby reducing its viscosity. The reduced viscosity of the raw material can make it easier to pass through the filter plate 13, while avoiding the problem that the temperature of the raw material is too high, which may cause difficulties in calendering and molding, affecting the quality and performance of the product, and the problem that the viscosity is too strong, which may cause the push plate.

[0051] like Figure 5 As shown, the first exhaust pipe 311 and the air intake pipe are both made of telescopic material, and a baffle is fixedly connected to the interior of the fixing rod 26 .

[0052] Specifically, when the movable plate 29 moves, the first exhaust pipe 311 and the air intake pipe are driven to expand and contract, and the baffle inside the fixed rod 26 can prevent the exhaust hot air from flowing in series.

[0053] Working principle: the raw material passes through the inside of the feed pipe 11, the driving motor 5 is turned on, the motor 5 drives the worm 51 to rotate, the worm 51 can mesh with the worm wheel 52, so that the worm wheel 52 can drive the rotating rod 2 to rotate, and the rotating rod 2 drives the scraper 21 to rotate to the discharge pipe 12. At this time, the raw material falls on the filter plate 13 by gravity, and the impurities in the raw material are filtered by the filter plate 13. At the same time, when the rotating rod 2 rotates, it will drive the moving rod 24 to rotate synchronously, and the moving rod 24 slides in the limiting groove 28. The moving rod 24 is in the reset section 281. At the same time, the heat exchange tube 39 performs heat exchange treatment on the push plate 4, and the heat exchange plate 37 performs heat exchange treatment on the fixed frame 36. When the moving rod 24 drives the moving wheel 25 to move to the push plate 4, the moving rod 24 drives the moving wheel 25 to move to the push plate 4. In section 282, the moving rod 24 is squeezed by the limiting groove 28, so that the moving rod 24 slides downward, the moving plate 29 drives the moving plate 29 to move downward, and the moving plate 29 drives the push plate 4 to slide downward. One end of the two push plates 4 is in contact with one side between the scrapers 21, so that the push plate 4 can push the raw material downward. The raw material is pushed by the push plate 4 and can quickly pass through the filter plate 13 and fall into the inside of the discharge pipe 12. The moving rod 24 drives the moving plate 29 to slide downward, so that the moving rod 24 drives the cross plate 314 and the piston 34 to slide inside the first pump pipe 22, so that the cross plate 314 squeezes the first spring 35, and the piston 34 pushes the cold air flow inside the first pump pipe 22 through the exhaust one-way The cooling air is sent into the interior of the heat exchange plate 37 through the valve 33, and then sent into the interior of the heat exchange tube 39 through the telescopic hose 38, so that the cooling air can cool the heat exchange plate 37 and the heat exchange tube 39. The hot air inside the heat exchange plate 37 and the heat exchange tube 39 is blown into the connecting pipe 310 by the cold air, and enters the second exhaust pipe 312 through the connecting pipe 310, enters the interior of the second pump pipe 23 through the second exhaust pipe 312, and then enters the second exhaust pipe 312 through the second pump pipe 23, and finally enters the exhaust sleeve 313 through the second exhaust pipe 312. The hot air in the exhaust sleeve 313 enters the fixed rod 26 through the air inlet 31, and is discharged from one end of the fixed rod 26. When the moving rod 24 is pushed out of the push section 2 When 82 enters the reset section 281, the moving rod 24 is driven to reset by the first spring 35, and the moving rod 24 drives the piston 34 to reset. The piston 34 moves upward and opens the air intake check valve 32, so that air is taken in at one end of the fixed rod 26 connected to the cold source. The cold air enters the air intake sleeve 3 through the air intake hole 31, and then enters the air intake check valve 32 from the air intake sleeve 3, and enters the first pump pipe 22 for storage through the air intake check valve 32. The operation is repeated to achieve the cooling treatment of the raw material, and then the rotating rod 2 continues to drive the scraper 21 to rotate. The subsequent group of scrapers 21 can push the impurities filtered on the filter plate 13, and push the impurities to the slag discharge port 14, and the impurities are automatically discharged through the slag discharge port 14.
