Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, specifically to a stretching device for an extruder with a heat preservation mechanism. Background Technology

[0002] During the extrusion process, stretching helps the plastic to mix and plasticize better in the screw, ensuring that the plastic changes from solid granules to a plastic viscous fluid, thereby improving the plasticizing effect, better controlling the flow state of the plastic, and reducing the impact of backflow and leakage.

[0003] Heating is required during extrusion to ensure good plasticity and fluidity of the plastic, so that it is not easy to break during stretching. It can also soften the plastic and reduce its viscosity. Currently used extrusion equipment only supports the wrapping insulation method, which forms an insulation layer by wrapping the outside. The insulation effect is generally poor and it is not suitable for high-requirement injection molding production, which greatly reduces the production efficiency of the equipment.

[0004] Therefore, a novel extruder stretching device with a heat preservation mechanism is proposed to solve the above problems. Utility Model Content

The heat preservation effect is generally poor and it is not suitable for high-requirement injection molding production, which greatly reduces the production efficiency of the equipment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an extruder stretching device with a heat preservation mechanism, comprising a main body of the device, mounting frames fixedly connected to both sides of the outside of the main body of the device, and a stable component for continuous heat preservation provided on the surface of the main body of the device;

[0007] The stabilizing component includes an electromagnetic coil wound at equal intervals around the outside of the main body of the device. The top and bottom of the outside of the main body of the device are fixedly connected to a limiting base plate. The two sets of limiting base plates are respectively located laterally at the top and bottom of the inside of the electromagnetic coil. Several sets of uprights are fixedly connected to the outer end of the limiting base plate, and a guide plate is fixedly connected to the top of the inner wall of the upright.

[0008] As a further technical solution of this utility model, the guide plate is fitted to the outer end of the electromagnetic coil, and connecting lines are provided through the bottom of the front ends on both sides of the electromagnetic coil.

[0009] As a further technical solution of this utility model, a first high-temperature heat insulation pad is attached to the front end of the inner wall of the main body of the equipment, a second high-temperature heat insulation pad is attached to the rear end of the inner wall of the main body of the equipment, and two sets of support frames are fixedly connected to the top and bottom ends inside the main body of the equipment.

[0010] As a further technical solution of this utility model, the first high-temperature heat insulation pad and the second high-temperature heat insulation pad respectively penetrate the interior of the two sets of support frames. The top and bottom of the rear end of the first high-temperature heat insulation pad are fixedly connected to a first connecting plate, and the top and bottom of the front end of the second high-temperature heat insulation pad are fixedly connected to a second connecting plate.

[0011] As a further technical solution of this utility model, the first connecting plate and the second connecting plate correspond one to one and fit together. The first connecting plate and the second connecting plate are both provided with positioning holes through the interior. The outer ends of the first connecting plate and the second connecting plate are provided with limiting collars.

[0012] As a further technical solution of this utility model, the front and rear ends of the limiting collar are both provided with insert rods, and the inner end of the insert rod is inserted into the inside of the positioning hole.

[0013] As a further technical solution of this utility model, a sealing gasket is provided through the left side of the main body of the equipment, and a door panel is fixedly connected to the outside of the sealing gasket. The door panel is fitted to the outside of the main body of the equipment. Fixed seats are fixedly connected to the front and rear ends of the left side of the main body of the equipment, and rotating rods are provided at the front and rear ends of the main body of the equipment.

[0014] As a further technical solution of this utility model, the two ends of the rotating rod are movably connected to the inner ends of two sets of fixed seats respectively. The outside of the rotating rod is fixedly connected to a limiting seat through a fixing member. The front end and rear end of the outer side of the door panel are both vertically fixedly connected to a fixed baffle. The limiting seat is sleeved on the outside of the fixed baffle and inserted into the inside of the fixed baffle.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the extruder stretching device with heat preservation mechanism not only realizes the efficient heat preservation function and the disassembly and assembly function, but also realizes the easy opening and closing function;

[0016] (1) By setting up an electromagnetic coil, a limiting base plate, a stand, a guide plate and a connecting line, the electromagnetic coil is wound around the outside of the main body of the equipment at equal intervals. After being energized through the connecting line, the electromagnetic energy is converted into heat energy by electromagnetic induction to heat the main body of the equipment and improve the heat preservation effect. Two sets of limiting base plates are installed horizontally at the top and bottom of the electromagnetic coil to provide strong support for both ends of the electromagnetic washer. The stand and the guide plate cooperate with each other to limit and fix the electromagnetic coil, so as to avoid the electromagnetic coil from shifting during the heating process, which would cause uneven heating of the main body of the equipment and affect the stretching effect.

[0017] (2) By setting a first high temperature heat insulation pad, a second high temperature heat insulation pad, a support frame, a first connecting plate, a second connecting plate and a limiting collar, the first high temperature heat insulation pad and the second high temperature heat insulation pad respectively penetrate through the interior of the two sets of support frames to ensure the fixation of the two and prevent the first high temperature heat insulation pad and the second high temperature heat insulation pad from sinking downward during use. The first connecting plate and the second connecting plate are attached to each other and the plug rod is fixed in the positioning hole by the plug-in connection method. The two sets are fixed by the limiting collar, which enhances the firmness between the first high temperature heat insulation pad and the second high temperature heat insulation pad, and at the same time facilitates disassembly and assembly, optimizing the flexibility of the structure.

[0018] (3) By setting up a limit seat, a fixed baffle, a rotating rod, a fixed seat, a door panel and a sealing gasket, the door panel fits against the outside of the main body of the equipment, and the sealing gasket is installed through the inside of the main body of the equipment, providing all-round sealing protection. The two ends of the rotating rod can rotate flexibly between the two sets of fixed seats, flipping the limit seat outward and fitting it onto the outside of the fixed baffle, enhancing the connection between the door panel and the main body of the equipment, and fixing the limit seat through the plug-in connection method, thereby improving the stability of the door panel.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 An extruder stretching device with a heat preservation mechanism includes a main body 2, mounting brackets 1 are fixedly connected to both sides of the outside of the main body 2, and a stable component for continuous heat preservation is provided on the surface of the main body 2.

[0026] The stabilizing component includes an electromagnetic coil 11, which is wound at equal intervals around the outside of the main body 2 of the equipment. Limiting base plates 12 are fixedly connected to the top and bottom of the outside of the main body 2. The two sets of limiting base plates 12 are respectively located laterally at the top and bottom of the inside of the electromagnetic coil 11. Several sets of uprights 13 are fixedly connected to the outer end of the limiting base plate 12. Guide plates 19 are fixedly connected to the top of the inner wall of the uprights 13.

[0027] The guide plate 19 is attached to the outer end of the electromagnetic coil 11, and the bottom of the front ends on both sides of the electromagnetic coil 11 is provided with connecting wires 18.

[0028] Specifically, such as Figure 1 and Figure 3 As shown, when in use, the electromagnetic coil 11 is wound around the outside of the device body 2 at equal intervals. After being energized through the connecting wire 18, the current is ensured to pass through the electromagnetic coil 11 and generate a magnetic field around it. When this magnetic field comes into contact with the device body 2, it will generate eddy currents inside it, causing the atoms inside the device body 2 to move at high speed and randomly. The atoms collide and rub against each other to generate heat energy, thus heating the device body 2.

[0029] A first high-temperature heat insulation pad 7 is attached to the front end of the inner wall of the main body 2, and a second high-temperature heat insulation pad 17 is attached to the rear end of the inner wall of the main body 2. Two sets of support frames 10 are fixedly connected to the top and bottom ends inside the main body 2.

[0030] The first high-temperature heat insulation pad 7 and the second high-temperature heat insulation pad 17 respectively penetrate the interior of the two sets of support frames 10. The top and bottom of the rear end of the first high-temperature heat insulation pad 7 are fixedly connected to the first connecting plate 8, and the top and bottom of the front end of the second high-temperature heat insulation pad 17 are fixedly connected to the second connecting plate 16.

[0031] The first connecting plate 8 and the second connecting plate 16 correspond to each other and fit together. The first connecting plate 8 and the second connecting plate 16 are both provided with positioning holes 14. The outer ends of the first connecting plate 8 and the second connecting plate 16 are provided with limiting collars 9.

[0032] The front and rear ends of the limiting collar 9 are both provided with insert rods 15, and the inner end of the insert rod 15 is inserted into the inside of the positioning hole 14.

[0033] Specifically, such as Figure 1 and Figure 2 As shown, when the main body 2 of the equipment is heated, the first high-temperature heat insulation pad 7 and the second high-temperature heat insulation pad 17 pass through the interior of the two sets of support frames 10 respectively. The first connecting plate 8 and the second connecting plate 16 are attached to each other, and the limiting collar 9 is sleeved on the outside of the outer end of the first connecting plate 8 and the second connecting plate 16 until the insertion rod 15 is inserted and fixed in the corresponding positioning hole 14, forming a safe heat insulation layer and providing strong heat insulation for the main body 2 of the equipment.

[0034] A sealing gasket 6 is provided through the left side of the main body 2. A door panel 3 is fixedly connected to the outside of the sealing gasket 6. The door panel 3 is fitted to the outside of the main body 2. A fixing seat 21 is fixedly connected to the front and rear ends of the left side of the main body 2. A rotating rod 20 is provided at the front and rear ends of the main body 2.

[0035] The two ends of the rotating rod 20 are movably connected to the inner ends of the two sets of fixed seats 21 respectively. The outside of the rotating rod 20 is fixedly connected to the limiting seat 4 through the fixing component. The front and rear ends of the outer side of the door panel 3 are vertically fixedly connected to the fixing baffle 5. The limiting seat 4 is sleeved on the outside of the fixing baffle 5 and inserted into the inside of the fixing baffle 5.

[0036] Specifically, such as Figure 1 and Figure 4 As shown, when in use, the door panel 3 is attached to the outside of the main body 2 of the equipment, and the sealing gasket 6 is located inside the main body 2 of the equipment to play a sealing and protective role. The rotating rod 20 rotates flexibly between the two sets of fixed seats 21, flips the limiting seat 4 outward, fits it on the outside of the fixed baffle 5, and inserts it to fix it in the current position, so as to effectively fix the door panel 3.

[0037] Working principle: In use, the electromagnetic coil 11 is wound around the outside of the main body 2 of the device at equal intervals. After being energized through the connecting wire 18, the current is ensured to pass through the electromagnetic coil 11 and generate a magnetic field around it. When this magnetic field comes into contact with the main body 2 of the device, it will generate eddy currents inside it, causing the atoms inside the main body 2 to move at high speed and randomly. The atoms collide and rub against each other to generate heat energy, thus heating the main body 2 of the device. After the main body 2 of the device is heated, the first high temperature heat insulation pad 7 and the second high temperature heat insulation pad 17 pass through the interior of the two sets of support frames 10 respectively. The first connecting plate 8 and the second connecting plate 16 are attached to each other, and the limiting collar 9 is sleeved on the outside of the outer end of the first connecting plate 8 and the second connecting plate 16 until the insertion rod 15 is inserted and fixed in the corresponding positioning hole 14, forming a safe heat insulation layer and providing strong heat insulation for the main body 2 of the device.

No reference numerals in the claims should be construed as limiting the scope of the claims.
