Description

A plastic extruder with an anti-jamming structure Technical Field

[0001] This utility model relates to the field of plastic processing technology, specifically to a plastic extruder with an anti-jamming structure. Background Technology

[0002] Extrusion molding is a highly versatile, productive, adaptable, and widely used molding process in the plastics processing industry, accounting for the largest proportion of production. Extrusion molding involves continuously shaping a molten polymer or viscous fluid through a die of a specific shape under the pressure of a screw or plunger in an extruder, resulting in a continuous profile with a constant cross-sectional shape. In plastic extrusion molding equipment, the plastic extruder is usually referred to as the main machine, while the downstream equipment, the plastic extrusion molding machine, is called the auxiliary machine. After more than 100 years of development, plastic extruders have evolved from single-screw machines to twin-screw, multi-screw, and even screwless models. The plastic extruder (main machine) can be matched with various auxiliary machines for plastic molding, such as pipes, films, rods, monofilaments, flat filaments, strapping, extruded mesh, sheets, profiles, granulation, and cable sheathing, to form various plastic extrusion molding production lines to produce a variety of plastic products. Therefore, plastic extrusion molding machinery remains one of the most widely used types of machinery in the plastics processing industry, both now and in the future.

[0003] Chinese patent CN113771330A discloses a plastic extruder relating to the field of power cord processing. It includes a machine body with a material inlet at its upper part. A feed hopper is installed at the material inlet, and a drying chamber is fixedly connected inside the feed hopper. A receiving hopper is fixedly connected to one side of the bottom of the drying chamber. A feed inlet is opened near the bottom of the receiving hopper in the drying chamber. A circulation device for material circulation is provided inside the drying chamber. A drying port and a discharge port are respectively provided on the top periphery of the drying chamber. A control device is provided at the drying port, and an adjustment device is provided at the discharge port. The drying port is located above the receiving hopper, and the discharge port is located above the material inlet. A blowing device for drying the material is provided at the drying port in the drying chamber.

[0004] In the plastic extruders of this utility model and the prior art, during the plastic extrusion process, due to excessive plastic being conveyed and not being cleaned in time, some plastic easily adheres to the outer wall of the spiral feed tube. When there is too much residual plastic, it is urgent for workers to clean it. When a large amount of plastic remains after each plastic processing, cleaning work is required, resulting in frequent equipment cleaning, which consumes manpower and time and has low applicability. At the same time, after plastic processing, due to the high internal temperature of the equipment, workers need to wait for a period of time to cool down before cleaning, which prevents workers from working early and thus affects cleaning efficiency.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention

[0014] Preferably, the transmission mechanism further includes a second belt and pressing rods. The second belt is sleeved on the rotating rod and the transmission rod, and a plurality of pressing rods are fixedly sleeved on the rotating rod and contact the arc-shaped slider when rotating.

[0015] Preferably, the melting mechanism further includes a material conveying pipe, which is fixedly connected to and communicates with the processing barrel.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a plastic extruder with an anti-jamming structure, which has the following beneficial effects:

[0019] 1. This type of plastic extruder with an anti-jamming structure works by first activating the cylinder to seal one side of the spiral feeding pipe with a stop block, then starting the first motor. The output of the first motor rotates, driving the spiral feeding pipe and the rotating rod to rotate. The rotating spiral feeding pipe conveys the crushed plastic, and the rotating rod drives several cooling fan blades to rotate. The rotation of the cooling fan blades lowers the temperature of the inner wall of the spiral feeding pipe, increasing the temperature difference between the inner and outer walls of the spiral feeding pipe, thereby reducing the probability of plastic adhesion and residue and improving material utilization.

[0020] 2. This type of plastic extruder with an anti-jamming structure drives several extrusion rods to rotate when the rotating rod rotates. When the extrusion rods rotate, they press against the arc-shaped slider and drive the arc-shaped slider to move vertically back and forth under the action of the return spring. When the arc-shaped slider moves, it drives the vibrating blocks to move, which in turn enables several vibrating blocks to intermittently vibrate the inner wall of the spiral feeding tube, further reducing the probability and amount of plastic adhesion and residue, and further improving the material utilization rate.

[0021] 3. This type of plastic extruder with an anti-jamming structure, by closing the cylinder and reversing the output end of the first motor, the output end of the cylinder retracts, so that the stop block no longer seals the spiral feeding pipe. At this time, both ends of the spiral feeding pipe are in an air-permeable state. The reversal of the output end of the first motor can drive the output ends of several cooling fan blades to reverse, so that the cooling fan blades can increase the air flow rate inside the processing barrel, thereby achieving a cooling effect. This makes it easier for the staff to clean the equipment earlier, improving cleaning efficiency and applicability. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0035] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a plastic extruder with an anti-jamming structure.

[0036] Please refer to Figures 1-10. A plastic extruder with an anti-jamming structure includes a support frame 1. A fixed frame 2 is fixedly installed at one end of the support frame 1, and a melting mechanism 3 is provided at the top. The melting mechanism 3 includes a processing barrel 301. Several high-temperature heaters are provided inside the processing barrel 301. A spiral feeding pipe 4 is rotatably connected to the inner wall of the processing barrel 301. A cooling component 5 and a vibration component 6 are provided at one end of the fixed frame 2. The cooling component 5 includes cooling fan blades 501, and the vibration component 6 includes vibration blocks 601. A transmission mechanism 7 is provided between the fixed frame 2 and the support frame 1. The transmission mechanism 7 can drive the cooling fan blades 501 to rotate and can drive the vibration blocks 601 to repeatedly impact the inner wall of the spiral feeding pipe 4. A cylinder 8 is fixedly installed at one end of the cooling component 5. A stop block 10 is fixedly installed at the output end of the cylinder 8. The stop block 10 is in contact with the inner wall of the spiral feeding pipe 4.

[0037] When plastic needs to be processed, the plastic part to be processed is poured into the conveying pipe 303, and the cylinder 8 and the transmission mechanism 7 are started. After the output end of the cylinder 8 extends, it can push the stop block 10 to move horizontally and seal one end of the spiral feeding pipe 4 to prevent plastic from entering the spiral feeding pipe 4.

[0038] After the transmission mechanism 7 is started, it can drive the spiral feeding tube 4 to rotate. After the spiral feeding tube 4 rotates, it can transport the crushed plastic to the side of the processing barrel 301 where a high-temperature heater is provided, so that the high-temperature heater can heat and melt the plastic. When the transmission mechanism 7 is started, it can also drive several cooling fan blades 501 to rotate and drive the vibrating block 601 to move back and forth vertically. After the several cooling fan blades 501 rotate, they can blow the air inside the spiral feeding tube 4 and increase the air circulation speed, thereby achieving the effect of reducing the internal temperature of the spiral feeding tube 4, so that there is a significant temperature difference between the inner and outer walls of the spiral feeding tube 4. By cooling, the probability of plastic adhering to the outer wall of the spiral feeding tube 4 and remaining is reduced.

[0039] When the vibrating block 601 moves vertically back and forth, it can impact the inner wall of the spiral feeding tube 4, thereby vibrating the plastic that is about to stick to the outer wall of the spiral feeding tube 4, further reducing the probability of plastic residue and adhesion, and improving applicability. After the plastic is extruded, the cylinder 8 is closed. The output end of the cylinder 8 can drive the stop block 10 to move, so that both ends of the spiral feeding tube 4 are opened. At this time, the drive source of the transmission mechanism 7 is reversed, which in turn causes several cooling fan blades 501 to reverse. After several cooling fan blades 501 reverse, the high temperature inside the processing barrel 301 can be quickly discharged, improving the cooling speed and making it easier for the staff to clean the processing barrel 301, thus improving the cleaning efficiency.

[0040] High-temperature heaters are existing technology and will not be explained here.

[0041] In one embodiment, the vibration assembly 6 further includes a support member 602, a connector 603, an arc-shaped slider 604, and a return spring 605. Several support members 602 are fixedly connected, one of which is fixedly connected to the connector 603. The arc-shaped slider 604 is slidably engaged with the support member 602. The vibration block 601 is fixedly connected to the arc-shaped slider 604. The two ends of the return spring 605 are respectively connected to the arc-shaped slider 604 and the support member 602. The connector 603 is fixedly connected to the fixing frame 2.

[0042] When the transmission mechanism 7 is started, the arc-shaped slider 604 is squeezed and moves vertically under the limit of the support 602. When the arc-shaped slider 604 moves, it squeezes the return spring 605 and drives the vibrating block 601 to move. Under the action of the return spring 605, the arc-shaped slider 604 and the vibrating block 601 can move vertically back and forth. After the vibrating block 601 moves, it can hit the inner wall of the spiral feeding pipe 4, causing the adhered plastic to fall off, reducing the probability of plastic residue, thereby reducing the frequency of equipment cleaning and improving applicability.

[0043] In one embodiment, the cooling assembly 5 further includes a rotating rod 502, and a plurality of cooling fan blades 501 are fixedly sleeved on the outer wall of the rotating rod 502. The mounting end of the cylinder 8 is fixedly connected to one end of the rotating rod 502, and the other end of the rotating rod 502 is rotatably connected to the fixing frame 2.

[0044] When the rotating rod 502 rotates, it drives several cooling fan blades 501 and the extrusion rod 709 to rotate. After the cooling fan blades 501 rotate, they can blow the air inside the spiral feeding tube 4 and increase the air flow speed, thereby reducing the internal temperature of the spiral feeding tube 4. This makes the temperature difference between the inner and outer walls of the spiral feeding tube 4 obvious, and reduces the probability of plastic adhering to the outer wall of the spiral feeding tube 4 and remaining there by cooling.

[0045] In one embodiment, the melting mechanism 3 further includes a fixed base 302, which is fixedly connected to the top of the support frame 1, and the processing barrel 301 is fixedly sleeved with the fixed base 302.

[0046] The fixed base 302 is used to support the processing machine barrel 301.

[0047] In one embodiment, the transmission mechanism 7 includes a mounting frame 701, a first motor 702, a rotating shaft 703, a transmission rod 704, a first belt 705, a main gear 706, and a secondary gear 707. The mounting frame 701 is fixedly connected to the bottom of the support frame 1. The mounting end of the first motor 702 is fixedly connected to the top of the mounting frame 701. The rotating shaft 703 is fixedly connected to the output end of the first motor 702. One end of the transmission rod 704 is rotatably connected to the fixed base 302. The first belt 705 is sleeved on the rotating shaft 703 and the transmission rod 704. The main gear 706 is fixedly sleeved on the transmission rod 704. The secondary gear 707 is fixedly connected to one end of the spiral feeding pipe 4 and meshes with the main gear 706.

[0048] When plastic needs to be processed, the first motor 702 is started. After the output end of the first motor 702 rotates, it first drives the rotating shaft 703 to rotate. After the output end of the rotating shaft 703 rotates, it drives the transmission rod 704 to rotate through the first belt 705. When the transmission rod 704 rotates, it can not only drive the main gear 706 to rotate, but the main gear 706 also drives the secondary gear 707 to rotate. When the secondary gear 707 rotates, it drives the spiral feeding pipe 4 to rotate. After the spiral feeding pipe 4 rotates, it can transport the crushed plastic to the side of the processing barrel 301 where a high-temperature heater is provided, so that the high-temperature heater can heat and melt the plastic.

[0049] In one embodiment, the transmission mechanism 7 further includes a second belt 708 and pressing rods 709. The second belt 708 is sleeved on the rotating rod 502 and the transmission rod 704. A plurality of pressing rods 709 are fixedly sleeved on the rotating rod 502 and contact the arc-shaped slider 604 when rotating.

[0050] When the transmission rod 704 rotates, it not only drives the main gear 706 to rotate, but also drives the rotating rod 502 to rotate via the second belt 708. The rotation of the rotating rod 502 drives several cooling fan blades 501 and extrusion rods 709 to rotate. The rotation of the cooling fan blades 501 blows the air inside the spiral feeding pipe 4 and increases the airflow speed, thereby reducing the internal temperature of the spiral feeding pipe 4. This creates a significant temperature difference between the inner and outer walls of the spiral feeding pipe 4, reducing the probability of plastic adhering to and remaining on the outer wall of the spiral feeding pipe 4. When the extrusion rods 709 rotate at one end... The device can resist and compress the arc-shaped slider 604. After being compressed, the arc-shaped slider 604 can move vertically under the limitation of the support member 602 and compress the return spring 605. When the arc-shaped slider 604 moves, it drives the vibrating block 601 to move. When the arc-shaped slider 604 is compressed to the maximum extent, the vibrating block 601 can hit the inner wall of the spiral feeding tube 4, thereby vibrating the plastic that is about to adhere to the outer wall of the spiral feeding tube 4. Under the action of the return spring 605, the arc-shaped slider 604 can repeatedly cooperate with the extrusion rod 709 to further reduce the probability of plastic residue and adhesion and improve applicability.

[0051] In one embodiment, the melting mechanism 3 further includes a material conveying pipe 303, which is fixedly connected to and communicates with the processing barrel 301. The material conveying pipe 303 is provided with a crushing component 9 inside, which includes a first crushing rod 901 and a second crushing rod 902, which are in relative reverse rotation.

[0052] Before the plastic is fed in, the first crushing rod 901 and the second crushing rod 902 are rotated to crush the plastic to be processed, thereby increasing the plastic melting speed.

[0053] In one embodiment, the crushing assembly 9 further includes a support arm 903, a second motor 904, a drive gear 905, and a driven gear 906. The support arm 903 is fixedly connected to the top of the support frame 1. The mounting end of the second motor 904 is fixedly connected to one end of the support arm 903, and the output end is fixedly connected to the first crushing rod 901. The first crushing rod 901 and the second crushing rod 902 are both rotatably connected to the conveying pipe 303. The drive gear 905 is fixedly sleeved on the first crushing rod 901, and the driven gear 906 is fixedly sleeved on the second crushing rod 902 and meshes with the drive gear 905.

[0054] When plastic needs to be processed, the operator first starts the second motor 904. After the output end of the second motor 904 rotates, it first drives the first crushing rod 901 to rotate. When the first crushing rod 901 rotates, it drives the drive gear 905 to rotate. When the drive gear 905 rotates, it drives the driven gear 906 to rotate in the opposite direction. After the driven gear 906 rotates, it drives the second crushing rod 902 to rotate. This causes the first crushing rod 901 and the second crushing rod 902 to rotate in the opposite direction. When the first crushing rod 901 and the second crushing rod 902 rotate, they can crush the input plastic parts, so that the plastic parts can be crushed before they are melted, thereby increasing the contact area between the plastic parts and the high temperature and improving the melting effect.

[0055] Working principle:

[0056] When plastic needs to be processed, the operator first starts the second motor 904. After the output end of the second motor 904 rotates, it first drives the first crushing rod 901 to rotate. When the first crushing rod 901 rotates, it drives the drive gear 905 to rotate. When the drive gear 905 rotates, it drives the driven gear 906 to rotate in the opposite direction. After the driven gear 906 rotates, it drives the second crushing rod 902 to rotate. This causes the first crushing rod 901 and the second crushing rod 902 to rotate in the opposite direction. When the first crushing rod 901 and the second crushing rod 902 rotate, they can crush the input plastic parts, so that the plastic parts can be crushed before they are melted, increasing the contact area between the plastic parts and the high temperature, and improving the melting effect. Then, the plastic parts to be processed are poured into the conveying pipe 303, and the cylinder 8 and the first motor 702 are started. After the output end of the cylinder 8 extends, it can push the stop block 10 to move horizontally and seal one end of the spiral feeding pipe 4.

[0057] After the output end of the first motor 702 rotates, it first drives the rotating shaft 703 to rotate. After the output end of the rotating shaft 703 rotates, it drives the transmission rod 704 to rotate through the first belt 705. When the transmission rod 704 rotates, it can not only drive the main gear 706 to rotate, but also drive the rotating rod 502 to rotate through the second belt 708. After the main gear 706 rotates, it drives the auxiliary gear 707 to rotate. When the auxiliary gear 707 rotates, it drives the spiral feeding pipe 4 to rotate. After the spiral feeding pipe 4 rotates, it can transport the crushed plastic to the side of the processing barrel 301 equipped with a high-temperature heater, so that the high-temperature heater can heat and melt the plastic. When the rotating rod 502 rotates, it drives several cooling fan blades 501 and the extrusion rod 709 to rotate. After the several cooling fan blades 501 rotate, they can blow the air inside the spiral feeding pipe 4 and increase the air circulation speed, thereby achieving the effect of reducing the internal temperature of the spiral feeding pipe 4. This makes the temperature difference between the inner and outer walls of the spiral feeding pipe 4 obvious, and reduces the probability of plastic adhering to the outer wall of the spiral feeding pipe 4 and remaining there by cooling.

[0058] When several extrusion rods 709 rotate to one end, they can abut against the arc-shaped slider 604 and extrude the arc-shaped slider 604. After being extruded, the arc-shaped slider 604 can move vertically under the limit of the support member 602 and extrude the return spring 605. When the arc-shaped slider 604 moves, it drives the vibration block 601 to move. When the arc-shaped slider 604 is extruded to the maximum limit, the vibration block 601 can hit the inner wall of the spiral feeding tube 4, thereby vibrating the plastic that is about to adhere to the outer wall of the spiral feeding tube 4, further reducing the probability of plastic residue and adhesion, and improving applicability.

[0059] After the plastic extrusion is completed, cylinder 8 is closed. The output end of cylinder 8 can drive the stop block 10 to move, so that both ends of the spiral feeding pipe 4 are opened. At this time, the output end of the first motor 702 is reversed. Through the cooperation of the rotating shaft 703, the second belt 708 and the rotating rod 502, several cooling fan blades 501 are reversed. After the several cooling fan blades 501 are reversed, the high temperature inside the processing barrel 301 can be quickly discharged, improving the cooling speed and making it easier for the staff to clean the processing barrel 301, thus improving the cleaning efficiency.

[0060] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
