Description

Technical Field

[0001] This utility model relates to the field of feeding and drying technology, and in particular to a feeding and drying device for an extruder. Background Technology

[0002] The main extrusion raw material used by extruders is plastic granule masterbatch. The plastic granule masterbatch is fed into the extruder, which has a built-in push screw and heating device. The heating device melts the masterbatch, and the push screw pushes the molten masterbatch to the extrusion head of the extruder. By setting the shape of the extrusion head mold, various products can be extruded. It is mainly used to make the insulation layer and sheath of cables.

[0003] Traditional extruder feeding processes may suffer from problems such as uneven material conveying and unstable feeding speed, affecting extrusion production efficiency and product quality uniformity. For example, manual feeding is inefficient and prone to material supply interruptions; some simple mechanical feeding devices cannot accurately control the feeding amount; if the material contains moisture, it may cause defects such as bubbles and rough surfaces in the product during extrusion. Furthermore, traditional drying methods may be energy-intensive, time-consuming, or result in uneven drying, failing to effectively meet the dryness requirements of extrusion production.

[0004] Therefore, it is necessary to provide an extruder feeding and drying device to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a feeding and drying device for an extruder, so as to solve the problems of the prior art mentioned in the background art.

[0006] Based on the above ideas, this utility model provides the following technical solution: a feeding and drying device for an extruder, comprising a support frame for feeding, a processing tank fixedly connected inside the support frame, and an auger conveyor fixedly connected outside the processing tank for conveying, and further comprising:

[0007] The rotating drum is rotatably connected to one end of the processing tank, and multiple partitions are fixedly connected to the outside of the rotating drum. Each adjacent partition is fixedly connected to a filter plate. When the material is transported to the processing tank by the auger conveyor, the material is screened by the filter plate.

[0008] The discharge frame is fixedly connected to the bottom of the processing tank, and a metering device is installed at the bottom of the discharge frame to control the metered discharge.

[0009] A drive motor is fixedly connected to the outside of the processing barrel. The output shaft of the drive motor passes through the processing barrel and is fixedly connected to the rotating cylinder. A drying device is provided on the top of the processing barrel, and a vent is provided inside the rotating cylinder for venting moisture. The vent is fixedly connected to the end of the processing barrel away from the drive motor.

[0010] As a further embodiment of this utility model: the drying device includes a ventilation hood, which is fixedly connected to the top of the processing barrel, and the ventilation hood is connected to an external hot air pipe.

[0011] As a further embodiment of this utility model: an exhaust pipe is fixedly connected to one end of the ventilation cylinder, the exhaust pipe passes through the processing barrel and is fixedly connected to the processing barrel, and is used to discharge the moisture generated by heating the material.

[0012] As a further embodiment of this utility model: the outer side of the ventilation cylinder is provided with an opening located below the ventilation hood, for the purpose of venting moisture.

[0013] As a further embodiment of this utility model: two rotating rollers are provided at the opening, and brushes are provided on the outer sides of the two rotating rollers, and both rotating rollers are rotatably connected by air cylinders.

[0014] As a further embodiment of this utility model: a gear disk is provided at one end of the venting cylinder near the drive motor, a support rod is fixedly connected to the outside of the gear disk, the support rod passes through the venting cylinder and is fixedly connected to the rotating cylinder, and gears are fixedly connected to one end of each of the two rotating rollers near the gear disk, and both gears are meshed with the gear disk.

[0015] As a further embodiment of this utility model: the quantitative device includes a sealing plate with a pressure sensor installed, a groove is provided on one side of the discharge frame, the sealing plate passes through the groove and seals the bottom of the discharge frame, and electric telescopic rods are fixedly connected to both ends of the discharge frame, with the telescopic ends of the electric telescopic rods fixedly connected to the outside of the sealing plate.

[0016] As a further embodiment of this utility model: a vent hole is provided on the outer side of the rotating cylinder, and the radius of the vent hole is smaller than the filter hole on the outer side of the filter plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The material rolls along the side wall of the processing drum. It is worth noting that the baffles are in contact with the inner wall of the processing drum. The material will be filtered through the filter plates between the adjacent baffles, separating and drying the large and small particles in the material. The large particles are distributed in an arc shape on the filter plates, while the small particles are distributed on the surface of the rotating drum. When the material rotates to the drying device as the drum rotates, the drying device dries the separated material, improving the drying effect of the material.

[0019] 2. The rotating roller has brushes on its outer side that pass through the ventilation holes to clean them and also to move the material around, thus improving the drying effect. When the rotating drum rotates, the support rod drives the gear disc to rotate, which in turn drives the meshing gears to rotate, thereby making the rotating roller rotate and improving efficiency.

[0020] 3. The material will fall into the discharge frame at the bottom of the processing tank. By installing a pressure sensor inside the sealing plate, when the material at the top of the sealing plate reaches the specified weight, the electric telescopic rod is activated. The electric telescopic rod pushes the sealing plate to move, thereby pouring out the material and achieving the effect of quantitative discharge. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0032] like Figures 1 to 7 As shown, an extruder feeding and drying device includes the following embodiments:

[0033] Example 1: Includes a support frame 1 for feeding, which is typically fixed to the feed inlet of the extruder. A processing tank 2 is fixedly connected inside the support frame 1, and an auger conveyor 3 for conveying is fixedly connected to the outside of the processing tank 2. The auger conveyor 3 can be an existing, commonly used auger conveyor model, which will not be further elaborated here. It also includes:

[0034] Rotating cylinder 6 is rotatably connected to one end of the processing tank 2, and multiple partitions 7 are fixedly connected to the outside of rotating cylinder 6. Each adjacent partition 7 is fixedly connected to a filter plate 8. When the material is transported to the processing tank 2 by the auger conveyor 3, the material is screened by the filter plate 8.

[0035] The discharge frame 4 is fixedly connected to the bottom of the processing tank 2, and a metering device is provided at the bottom of the discharge frame 4 to control the metered discharge.

[0036] A drive motor 11 is fixedly connected to the outside of the processing tank 2. The output shaft of the drive motor 11 passes through the processing tank 2 and is fixedly connected to the rotating cylinder 6. A drying device is provided on the top of the processing tank 2, and a ventilator 9 for venting moisture is provided inside the rotating cylinder 6. The ventilator 9 is fixedly connected to the end of the processing tank 2 away from the drive motor 11.

[0037] In practice, when materials need to be conveyed, they are transported to the processing drum 2 via the auger conveyor 3. At this time, the materials fall between the rotating drum 6, the two partitions 7, and the inner wall of the processing drum 2. When the drive motor 11 is started, the output shaft of the drive motor 11 drives the rotating drum 6 to rotate. The rotating drum 6 drives the multiple partitions 7 on the outside to rotate. The materials roll against the side wall of the processing drum 2. It is worth noting that the partitions 7 are in contact with the inner wall of the processing drum 2. The materials will be filtered through the filter plates 8 between the adjacent partitions 7 to separate and dry the large and small particles in the materials. The large particles are distributed in an arc shape on the filter plates 8, while the small particles are distributed on the surface of the rotating drum 6. When the materials rotate to the drying device as the rotating drum 6 rotates, the drying device dries the separated materials to improve the drying effect of the materials.

[0038] In this embodiment, the drying device includes a ventilation hood 5, which is fixedly connected to the top of the processing barrel 2 and is connected to an external hot air pipe.

[0039] In practice, external hot air is introduced into the ventilation hood 5 through pipes, and then the ventilation hood 5 dries the material. The hot air can be combined with a fan and a heater.

[0040] Example 2: One end of the ventilation cylinder 9 is fixedly connected to an exhaust pipe 902, which passes through the treatment tank 2 and is fixedly connected to the treatment tank 2, and is used to discharge the moisture generated during material heating.

[0041] An opening 901 is provided on the outside of the ventilation cylinder 9. The opening 901 is located below the ventilation hood 5 and is used to discharge moisture.

[0042] A vent is provided on the outer side of the rotating cylinder 6, and the radius of the vent is smaller than the filter holes on the outer side of the filter plate 8.

[0043] In practice, when the material is heated, water vapor will be discharged. In this solution, by setting an opening 901, when the vent hood 5 discharges hot air, the moisture of the material is discharged into the vent cylinder 9 through the vent hole on the outside of the rotating cylinder 6, and discharged through the exhaust pipe 902. An air suction device can be set at one end of the exhaust pipe 902 to improve the flow of gas.

[0044] In this embodiment, two rotating rollers 10 are provided at the opening 901, and brushes are provided on the outer side of the two rotating rollers 10. Both rotating rollers 10 are rotatably connected to the air cylinder 9.

[0045] A gear disk 102 is provided at one end of the ventilator 9 near the drive motor 11. A support rod is fixedly connected to the outside of the gear disk 102. The support rod passes through the ventilator 9 and is fixedly connected to the rotating cylinder 6. Gears 101 are fixedly connected to one end of each of the two rotating rollers 10 near the gear disk 102. Both gears 101 are meshed with the gear disk 102.

[0046] In a specific implementation, when the rotating drum 6 is rotating, the brush on the outside of the rotating roller 10 passes through the ventilation hole to clean the ventilation hole and also to move the material to rotate, thereby improving the drying effect of the material. When the rotating drum 6 is rotating, the support rod drives the gear disk 102 to rotate, and the gear disk 102 drives the meshing gear 101 to rotate, thereby causing the rotating roller 10 to rotate, thereby improving efficiency.

[0047] Example 3: The metering device includes a sealing plate 401 with a pressure sensor installed. A groove is provided on one side of the discharge frame 4. The sealing plate 401 passes through the groove and seals the bottom of the discharge frame 4. Both ends of the discharge frame 4 are fixedly connected to an electric telescopic rod 402. The telescopic end of the electric telescopic rod 402 is fixedly connected to the outside of the sealing plate 401.

[0048] In practice, after the material is dried, as the rotating drum 6 rotates, the material will fall into the discharge frame 4 at the bottom of the processing drum 2. By installing a pressure sensor inside the sealing plate 401, when the material at the top of the sealing plate 401 reaches the specified weight, the electric telescopic rod 402 is activated. The electric telescopic rod 402 pushes the sealing plate 401 to move, thereby pouring out the material and achieving the effect of quantitative discharge.
