Description

A high-precision, high-speed casting machine Technical Field

[0001] This invention relates to the field of casting machine technology, specifically a high-precision, high-speed casting machine. Background Technology

[0002] A casting machine is a piece of equipment used for the continuous production of plastic films. It employs an extrusion process, extrudes molten plastic through an extrusion system into a thin, wide film, and then processes it through cooling, traction, and winding to ultimately produce a flat, continuous plastic film product. After extrusion, the film is rapidly cooled by cooling rollers to lower its temperature and solidify it. The quality and properties of the film can be adjusted by controlling the temperature and speed of the cooling rollers. Next, the film is stretched by traction rollers, which control the film's speed and tension, maintaining its stable width and thickness.

[0003] Casting machines have some drawbacks in production. They consume a lot of energy during heating and cooling. In addition, operators usually manually feed the plastic film into the stretching area of ​​the casting machine at the feed end. During operation, operators need to manually maintain appropriate traction to ensure that the plastic film can pass evenly through the entire processing area of ​​the casting machine. This consumes manpower and has low operating efficiency. Furthermore, the stability of manual operation is poor. Excessive pulling force can easily lead to waste of excess material and reduce production accuracy. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This invention involves feeding raw materials into a hopper, which then conveys them to an extrusion device. A thermostat controls an electric heating mechanism to heat the material, melting it and extruding it into a storage box. The melting process can be monitored by opening the sealed cover on top of the storage box. The raw material is then diverted and extruded into the storage hopper by a diversion pipe. A servo motor drives a drive bevel gear, which in turn drives a bidirectional threaded rod, causing two sets of moving frames to move in opposite directions. This adjusts the distance between the two sets of extrusion storage rollers. A distance sensor monitors the distance between the rollers, allowing for adjustment of the feeding thickness. A magnetic cover plate and the rotating frame hold the plastic film head in place. A reciprocating unit is then activated, and a connecting mechanism drives a traction mechanism along the traction path, pulling the plastic film between the casting rollers. This allows for rapid processing of the film across the entire casting machine's processing area, facilitating adjustments to the feeding process, ensuring processing accuracy, improving debugging efficiency, and reducing manpower and material waste.

[0019] This invention also involves simultaneously energizing the Peltier blocks on both sides of the molten material as it is injected into the storage hopper, with the heat-dissipating surfaces close to the heat-conducting plates. The heat is then transferred to the storage hopper through the heat-conducting plates to heat and maintain the temperature of the molten material. At the same time, the heat-absorbing surfaces on the outer sides begin to absorb heat, and the negative pressure fan is activated to create a negative pressure in the cooling chamber. This negative pressure draws air through the exhaust pipe and the heat-absorbing pipe. The outside air enters the heat-absorbing pipe through the filter unit, where it is filtered to remove impurities and dust. It then enters the heat-absorbing pipe, where the heat in the air is absorbed by the Peltier blocks for cooling. The air then enters the cooling chamber through the exhaust pipe and is blown out by the negative pressure fan to cool and shape the plastic film. This effectively reduces energy consumption, saves energy and is environmentally friendly, while ensuring processing quality.

[0020] This invention also measures the thickness of the cooled plastic film using a thickness gauge, thereby ensuring production accuracy and quality. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1

[0035] Please refer to Figures 1-11. This invention provides a technical solution comprising: a base 1, a material extrusion device 2 connected to the top of the base 1, a feeding hopper 3 connected to the top of the material extrusion device 2, and a temperature controller 4 connected to one side of the base 1. An electric heating frame is connected to the outer surface of the material extrusion device 2, and the electric heating frame is electrically connected to the temperature controller 4. The material distribution device 2 is prior art and therefore not described in detail. A sampling and insulation box 5 is connected to one end of the material extrusion device 2, and a diversion pipe 6 is connected to one side of the sampling and insulation box 5. A fixed side plate 7 is connected to one side of the base 1. A feeding mechanism 8 is connected to one end of the diversion pipe 6, and insulation mechanisms 9 are connected to both sides of the feeding mechanism 8. A heat absorption pipe 10 is connected to one side of the insulation mechanism 9, and a filter unit 11 is connected to one end of the heat absorption pipe 10. The other end is connected to an exhaust pipe 12, one end of which is connected to a cooling chamber 13. A negative pressure fan 14 is connected to the bottom of the inner wall of the cooling chamber 13. A connecting seat 15 is connected to one side of the fixed side plate 7. A thickness gauge display unit 16 is connected to one side of the connecting seat 15. A thickness gauge detection end 161 is connected to the top of the connecting seat 15. One side of the thickness gauge detection end 161 is electrically connected to the thickness gauge display unit 16. Multiple sets of casting rollers 17 are rotatably arranged on one side of the fixed side plate 7. A reciprocating unit 18 is connected to the back of the fixed side plate 7. A connecting mechanism 19 is connected to one side of the reciprocating unit 18. A traction mechanism 20 is connected to one side of the connecting mechanism 19. A traction path hole 21 is opened on one side of the fixed side plate 7. A winding frame 22 is connected to one side of the fixed side plate 7.

[0036] The traction mechanism 20 includes a traction shaft 201, a rotating frame 202 rotatably mounted on the surface of the traction shaft 201, and return springs 203 connected to both ends of the inner wall of the rotating frame 202. A fixed clamping plate 204 is rotatably mounted on the surface of the rotating frame 202. A tension sensor 205 is connected to one end of the traction shaft 201, with one side of the tension sensor 205 in contact with the rotating frame 202. The other end of the traction shaft 201 is connected to the connecting mechanism 19. During debugging, the plastic film head is fixed between the fixed clamping plate 204 and the rotating frame 202. As the connecting mechanism 19 moves, the plastic film exerts a reverse pulling force on the rotating frame 202, thereby causing the rotating frame 202 to rotate slightly. The tension sensor 205 at one end detects the tension, thereby controlling the moving speed of the reciprocating unit 18 to avoid excessive tension from damaging the plastic film.

[0037] The fixing clamp 204 includes a magnetic cover plate 2041, and an anti-slip layer 2042 is provided on the inner side of the magnetic cover plate 2041. The plastic film head is clamped by the adsorption effect between the magnetic cover plate 2041 and the rotating frame 202, and the anti-slip layer 2042 effectively plays an anti-slip role.

[0038] The feeding mechanism 8 includes a storage hopper 81 and a servo motor 87. Both sides of the storage hopper 81 are rotatably equipped with bidirectional threaded rods 82. Movable frames 83 are connected to both ends of the bidirectional threaded rods 82. Sliding holes are opened on both sides of the storage hopper 81. On the side of the movable frames 83 that is closer to each other, a pressing storage roller 84 is rotatably mounted through the sliding hole. Distance sensors 85 are connected to the sides of the movable frames 83 that are further apart. A driven bevel gear 86 is connected to one end of the bidirectional threaded rod 82, and a driving bevel gear 88 is connected to the output end of the servo motor 87. One side of the driving bevel gear 88 meshes with the driven bevel gear 86. When the molten material in the storage hopper 81 flows downwards, it is discharged by adjusting the distance between the two sets of pressing storage rollers 84, thereby initially controlling the thickness of the plastic film. The distance sensor 85 can detect the distance between the pressing storage rollers 84 for easy observation.

[0039] The extrusion storage roller 84 is located inside the outlet at the bottom of the storage hopper 81. The storage hopper 81 has mounting grooves on both sides corresponding to the heat preservation mechanism 9, which can effectively transfer the temperature to the storage hopper 81, ensuring the heating effect of the molten material and thus ensuring its fluidity.

[0040] The reciprocating unit 18 includes a guide rail 181, a lead screw 182 rotatably mounted inside the guide rail 181, one end of the lead screw 182 passing through the guide rail 181 and connected to a drive motor 183, and one end of the lead screw 182 connected to a sliding block 184. A main support frame 185 is connected to one side of the sliding block 184, and a secondary support frame 186 is connected to one side of the main support frame 185. A connecting mechanism 19 is slidably connected to the main support frame 185 and the secondary support frame 186. The drive motor 183 starts the lead screw 182 to rotate, causing the sliding block 184 to move, thereby causing the main support frame 185 and the secondary support frame 186 to move. The connecting mechanism 19 drives the traction mechanism 20 to move, so as to traction the plastic film.

[0041] The connecting mechanism 19 includes a connecting shaft 191. One end of the connecting shaft 191 is connected to a sliding frame 192 and a sliding frame 193. The sliding frame 192 is slidably connected to the main support frame 185, and the sliding frame 193 is slidably connected to the auxiliary support frame 186. One end of the connecting shaft 191 is connected to a bearing 194, which is located inside the traction path hole 21. While driving the traction mechanism 20 to move, the outer ring of the bearing 194 will rotate while moving along the traction hole diameter 21. The traction hole diameter 21 restricts the path of the connecting shaft 191. The sliding frame 192 and the sliding frame 193 slide up and down within the main support frame 185 and the auxiliary support frame 186. The sliding frame 192 and the sliding frame 193 can ensure the movement stability of the connecting shaft 191.

[0042] A partition is connected to the middle of the traction shaft 201. One end of the return spring 203 is connected to the partition, and the other end is connected to one side of the inner wall of the rotating frame 202. This facilitates the return spring 203's return effect on the rotating frame 202, thereby ensuring that the tension sensor 205 automatically resets the detection value after debugging.

[0043] Working principle: In use, the raw material is fed into the feeding hopper 3 and then conveyed to the extrusion device 2. The heating mechanism controlled by the temperature controller 4 heats the plastic raw material, causing it to melt in the extrusion device 2 and be extruded into the storage box 5. The melting status of the raw material can be checked by opening the sealing cover on the top of the storage box 5. Then, the raw material is diverted and extruded into the storage hopper 81 by the diversion pipe 6. The servo motor 87 is started to drive the active bevel gear 88 to rotate, which drives the bidirectional threaded rod 82 to rotate through the driven bevel gear 86. This drives the two sets of moving frames 83 to move in opposite directions, thereby adjusting the two sets of extrusion devices. The spacing between the pressing and storing rollers 84 can be monitored by the distance sensor 85, thereby adjusting the feeding thickness. The plastic film head is held by the adsorption force between the magnetic cover plate 2041 and the rotating frame 202. Then, the drive motor 183 is started, and the sliding block 184 is moved by the lead screw 182, thereby moving the main support frame 185 and the auxiliary support frame 186. The connecting mechanism 19 drives the traction mechanism 20 to travel along the traction path hole 21, thereby pulling the plastic film through the casting rollers 17, thus quickly passing the plastic film through the entire processing area of ​​the casting machine.

[0044] Example 2

[0045] Please refer to Figures 1-11. This invention provides a technical solution:

[0046] The heat preservation mechanism 9 includes a mounting frame 91. A Peltier block 92 is connected to one side of the mounting frame 91. A heat-conducting plate 93 is connected to the side of the mounting frame 91 near the storage hopper 81, and a heat-absorbing frame 94 is connected to the other side. One side of the Peltier block 92 is attached to the heat-absorbing frame 94. The heat-absorbing tube 10 is curved and inserted into one side of the heat-absorbing frame 94. According to the Peltier effect, after being energized, the side of the Peltier block 92 facing the storage hopper 81 is the heat-releasing surface (high-temperature surface), and the other side is the heat-absorbing surface (low-temperature surface), thereby heating the molten material in the storage hopper 81.

[0047] The filter unit 11 includes a filter box 111. A filter layer 112 is connected to one side of the inner wall of the filter box 111. An air inlet 113 is opened on one side of the filter box 111. Air enters the filter box 111 through the air inlet 113 and is filtered by the filter layer 112, which can effectively ensure the cleanliness of the air and prevent secondary pollution when blowing out the plastic film.

[0048] One end of the exhaust pipe 12 is connected to an insulation layer, and the other end is connected to a connecting cover 23. The connecting cover 23 is connected to the top of the cooling chamber 13 to ensure that the low-temperature air maintains a low temperature effect when it is transmitted in the exhaust pipe 12, thereby ensuring the cooling effect on the plastic film.

[0049] Multiple sets of casting rollers 17 are arranged vertically and horizontally to form a processing area for the plastic film. The path distribution of the traction path holes 21 is set between the casting rollers 17 to ensure that when the traction mechanism 20 drives the plastic film to be pulled, it can effectively pass between each casting roller 17.

[0050] Working principle: When the molten material is injected into the storage hopper 81, the Peltier blocks 92 on both sides are energized, and the heat-dissipating surface is close to the heat-conducting plate 93. The heat is transferred to the storage hopper 81 through the heat-conducting plate 93 to heat and keep the molten material warm. At the same time, the heat-absorbing surface on the outside begins to absorb heat, and the negative pressure fan 14 is started to form a negative pressure in the cooling chamber 13. Air is drawn in through the exhaust pipe 12 and the heat-absorbing pipe 10. The outside air enters the heat-absorbing pipe 10 through the filter unit 11, is filtered by the filter layer 112 to remove impurities and dust, and then enters the heat-absorbing pipe 10. At the same time, the heat in the air is absorbed by the Peltier blocks 92 for cooling, and then enters the cooling chamber 13 through the exhaust pipe 12 and is blown out by the negative pressure fan 14 to cool and shape the plastic film.
