Description

Technical Field

[0001] This utility model relates to the field of screw extruder technology, specifically a screw extrusion device for the production of nylon raw materials. Background Technology

[0002] Nylon is a plastic made of polyamide resins. It can be produced by the condensation reaction of diamines and diacids, or by the ring-opening polymerization of lactams formed by the dehydration of amino acids. A significant characteristic of nylon is its distinct softening point and melting point, which ranges from 215 to 225 degrees Celsius. Nylon engineering plastics appear as horny, tough, glossy, white or slightly yellow, transparent or translucent crystalline resins. Nylon raw materials are processed and produced using a screw extruder.

[0003] In actual use, the existing extruders for producing nylon raw materials require the nylon raw material to be added to the feed hopper and discharged into the extrusion tube. The spiral blades on the screw then transport the nylon raw material to the extrusion die within the extrusion tube. During the transport process, the raw material is heated to a molten state before extrusion. However, the feeding of nylon raw materials is done manually. An iron frame ladder is built at the outside of the extruder, and workers use this ladder to feed the material. Since there are no protective structures on either side of the iron frame ladder, and the bagged nylon raw material is quite heavy, manual feeding poses certain safety hazards. In addition, the large amount of nylon raw material accumulated in the feed hopper results in a slow discharge speed, which can easily cause blockages, requiring manual stirring of the nylon raw material to clear the blockages. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a screw extrusion device for the production of nylon raw materials. The feeding component facilitates the addition of nylon raw materials without the need for manual feeding using iron ladders. This solves the safety hazard caused by workers using iron ladders for feeding, as the ladders lack protective structures on both sides. Furthermore, the anti-blocking component generates vibration force on the nylon raw materials accumulated inside the feed hopper, dispersing and clearing the material to prevent blockage of the bottom channel of the feed hopper and ensuring smooth material flow for processing.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution:

All three vibration rods are inserted and fixed to the three connecting sleeves.

[0009] Preferably, a motor housing is fixedly installed at one end of the extrusion tube, and a drive motor connected to the screw is installed inside the motor housing. A heating box is fixedly installed at the other end of the extrusion tube, and a heating coil is provided inside the heating box.

[0023] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0024] Example

[0025] like Figures 1-5 As shown, a screw extrusion device for producing nylon raw materials includes: an extruder 1, an extrusion tube 101 installed on the top of the extruder 1, a feed hopper 102 installed on the top of the extrusion tube 101, a screw 103 disposed inside the extrusion tube 101, the screw 103 having a plurality of helical blades, a feeding assembly disposed on one side of the outer end of the extruder 1, the feeding assembly including: a feed hopper 2, a feed tube 201, a support frame 202, a servo motor 203 and a discharge tube 204, and an anti-blocking assembly disposed on the outer end of the feed hopper 102, the anti-blocking assembly including: a connecting sleeve 3, a vibration motor 301 and a vibration rod 302.

[0026] The extruder 1 has a feeding hopper 2 on one side of its outer end. A feeding pipe 201 is installed at the bottom of the feeding hopper 2, and a feeding auger is installed inside the feeding pipe 201. A support frame 202 is installed at the bottom of the feeding hopper 2, and one end of the support frame 202 is welded and fixed to the extruder 1. A servo motor 203 connected to the feeding auger drive is installed at the bottom of the feeding pipe 201. A discharge pipe 204 is installed on one side of the top of the feeding pipe 201. When the extruder 1 is in use, the feeding hopper 2 is fixedly installed on the outer end of the extruder 1 via the support frame 202, and the feeding pipe 201 is placed close to the top of the feeding hopper 102, so that the discharge pipe 204 at the top of the feeding pipe 201 is located inside the feeding hopper 102. Then, nylon raw material is added... The nylon material is fed into the feeding hopper 2 and then discharged into the feeding pipe 201. A control panel is installed on the outside of the extruder 1. The servo motor 203 is connected to the control panel by wires. When the servo motor 203 is started on the control panel, it drives the feeding auger to rotate. The feeding auger comes into contact with and rubs against the nylon material inside the feeding pipe 201, conveying the nylon material upward. When it passes through the discharge pipe 204, the nylon material can be discharged into the feeding hopper 102, which makes it easy to add nylon material. There is no need to build an iron frame ladder for manual feeding, which solves the problem of safety hazards caused by workers using iron frame ladders for feeding operations, since there are no protective structures on both sides of the iron frame ladder.

[0027] One end of the extrusion tube 101 is fixedly mounted with a motor housing 104, and a drive motor 105 connected to the screw 103 is installed inside the motor housing 104. The other end of the extrusion tube 101 is fixedly mounted with a heating box 106, and a heating coil 107 is provided inside the heating box 106. The heating coil 107 is wound around the outside of the extrusion tube 101. An extrusion die 108 is installed at the outer end of the extrusion tube 101. After the nylon raw material is conveyed into the feed hopper 102, the drive motor 105 and the heating coil 107 are connected to the control console by wires. The control console starts the drive motor 105 and the heating coil 107 to work. The drive motor 105 drives the screw 103 to rotate. The screw 103 drives several spiral blades to rotate and contact and rub against the nylon raw material, conveying the nylon raw material to the extrusion die 108. During the conveying process, the heating coil 107 heats the nylon raw material inside the extrusion tube 101, so that the nylon raw material is heated to a hot melt state and conveyed to the extrusion die 108 for extrusion molding.

[0028] The feeding pipe 201 is fitted with a fixing sleeve 205, and a support rod 206 is welded to the bottom of the fixing sleeve 205. The bottom of the support rod 206 is fixed to the support frame 202 by bolts. When the feeding pipe 201 is in use, the fixing sleeve 205 is fitted and fixed on the feeding pipe 201, and the support rod 206 at the bottom of the fixing sleeve 205 is installed on the support frame 202. This allows the fixing sleeve 205, the support rod 206 and the support frame 202 to support and fix the feeding pipe 201, preventing the feeding pipe 201 from tipping over and affecting the feeding.

[0029] The feed hopper 102 has three connecting sleeves 3 installed on its outer end. A vibration motor 301 is installed on the outside of the connecting sleeves 3, and three vibration rods 302 are installed on the inside of the vibration motor 301. The three vibration rods 302 are all inserted and fixed to the three connecting sleeves 3. During the use of the feed hopper 102, after the nylon raw material is added into the feed hopper 102, the amount of nylon raw material inside the feed hopper 102 is large and piled up together, resulting in limited material discharge space inside the feed hopper 102. The vibration motor 301 is connected to the control console through a wire. The vibration motor 301 is started by the control console. After the vibration motor 301 vibrates, the vibration is transmitted to the feed hopper 102 through the vibration rods 302, thereby generating vibration force on the nylon raw material piled up inside the feed hopper 102, dispersing the nylon raw material and clearing the discharge channel, preventing the nylon raw material from blocking the channel at the bottom of the feed hopper 102, and ensuring smooth material discharge for processing and production.

[0030] The vibratory motor 301 is fixedly mounted with a motor base 303 by bolts at its outer end. The top of the extruder 1 is fixedly mounted with a fixing plate 304. The fixing plate 304 and the motor base 303 are fixedly mounted with bolts. When the vibratory motor 301 is in use, it is fixedly mounted with the motor base 303 and the fixing plate 304 by bolts. The fixing plate 304 provides support for the vibratory motor 301, so that the vibratory motor 301 can be used stably.

[0031] Multiple dampers 4 are installed on the support rod 206 and the outer end of the extruder 1. Each damper 4 is fitted with a buffer spring 401. When the vibrating motor 301 vibrates the feed hopper 102 to clear the material, the feed hopper 102 will transmit the vibration force to the feeding pipe 201. The feeding pipe 201 is supported by the support rod 206. The damper 4 and the buffer spring 401 are installed between the support rod 206 and the extruder 1. The damper 4 and the buffer spring 401 can reduce the vibration force on the support rod 206 and prevent the feeding pipe 201 and the support rod 206 from becoming unstable after being vibrated.

[0032] Working principle:

[0033] When the extruder 1 is in use, the feeding hopper 2 is fixedly installed on the outer end of the extruder 1 by the support frame 202, and the feeding pipe 201 is placed close to the top of the feeding hopper 102, so that the discharge pipe 204 at the top of the feeding pipe 201 is located inside the feeding hopper 102. Then, nylon raw material is added into the feeding hopper 2, and the nylon raw material inside the feeding hopper 2 will be discharged into the feeding pipe 201. A control console is installed on the outside of the extruder 1. The servo motor 203 is connected to the control console by wire. When the servo motor 203 is started on the control console, the servo motor 203 drives the feeding auger to rotate. The feeding auger contacts and rubs against the nylon raw material inside the feeding pipe 201, conveying the nylon raw material upward. When passing through the discharge pipe 204, the nylon raw material can be discharged into the feeding hopper 102, which is convenient for adding nylon raw material. There is no need to build an iron frame ladder for manual feeding, which solves the problem of workers using iron frame ladders for feeding operations, which poses a safety hazard because there are no protective structures on both sides of the iron frame ladder.

[0034] After the nylon raw material is fed into the hopper 102, its drive motor 105 and heating coil 107 are connected to the control console via wires. The control console starts the drive motor 105 and heating coil 107 to work. The drive motor 105 drives the screw 103 to rotate. The screw 103 drives several spiral blades to rotate and contact and rub against the nylon raw material, conveying the nylon raw material to the extrusion die 108. During the conveying process, the heating coil 107 heats the nylon raw material inside the extrusion tube 101, so that the nylon raw material is heated to a hot melt state and conveyed to the extrusion die 108 for extrusion molding.

[0035] During the use of the feeding hopper 102, after the nylon raw material is added into the feeding hopper 102, the amount of nylon raw material inside the feeding hopper 102 is large and piled up, resulting in limited material discharge space inside the feeding hopper 102. The vibration motor 301 is connected to the control console via wires. The vibration motor 301 is started by the control console. After the vibration motor 301 generates vibration, it transmits the vibration to the feeding hopper 102 through the vibration rod 302, thereby generating vibration force on the nylon raw material piled up inside the feeding hopper 102, dispersing the nylon raw material and clearing the material for discharge, avoiding the nylon raw material blocking the channel at the bottom of the feeding hopper 102, and ensuring smooth material discharge for processing and production.
