Description

Technical Field

[0001] This utility model relates to the technical field of resin extrusion devices, and in particular to a multifunctional ABS resin melt extrusion device. Background Technology

[0002] The ABS resin melt extrusion unit is a comprehensive equipment that integrates raw material pretreatment, melt plasticizing, mixing and modification, and molding extrusion. Its core function is to process solid ABS resin or mixtures containing modifiers into a continuous melt flow by heating and melting, and shearing and mixing with a screw. The melt is then extruded into specific shapes, such as strips, sheets, pipes, and profiles, through different dies. It can also integrate a variety of auxiliary functions to adapt to diverse processing needs.

[0003] The ABS resin is selected according to processing requirements, and modifiers are mixed according to the formula. For example, 1-5% silicone powder needs to be added for anti-stick ABS, and 10-30% glass fiber needs to be added for reinforced ABS. The core value of the extrusion device lies in its ability to produce ABS products of different shapes and specifications, such as strip granules, sheets, pipes, and profiles. Different products rely on dies with different structures, such as slot dies, T-die dies, and round dies. Extrusion production is highly continuous, and downtime directly affects production capacity. Traditional die installation requires the removal of dozens of bolts and calibration of coaxiality, which usually takes 1-2 hours. Traditional die replacement requires 2-3 skilled workers to work together to remove bolts, move the die, and calibrate its position. This is labor-intensive and requires a high level of skill. Therefore, we propose a multi-functional ABS resin melt extrusion device to solve the existing problems. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a multifunctional ABS resin melt extrusion device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional ABS resin melt extrusion device, comprising a guide rail, a connecting pipe, a slider, an extrusion pipe, a motor one, and a motor two. A slider is slidably installed inside the guide rail. The slider has equidistantly distributed stroke openings inside. A stroke opening is located at the center of the guide rail. An extrusion pipe corresponding to the stroke opening is provided at one end of the guide rail. Connecting pipes are slidably inserted into each stroke opening inside the slider. A support ring is provided on one side of the slider. A mating ring fitted onto the outer wall of the connecting pipe is provided on one side of the support ring. A die opening of varying specifications is provided at one end of the connecting pipe. Symmetrically distributed pressure plates are provided on one side of the support ring.

[0006] Preferably, the support ring and the slider are provided with springs arranged in a circular array at one end. The support ring is elastically supported by the springs, so that the mating ring located inside the support ring is elastically supported.

[0007] Preferably, a sliding sleeve is embedded inside the pressure plate, and a guide rod with one end connected to the guide rail is slidably inserted inside the sliding sleeve. During the movement of the pressure plate, the sliding sleeve slides on the outer wall of the guide rod, guiding the pressure plate. The pressure plate is used to hold the support ring, thereby allowing the connecting pipe to move.

[0008] Preferably, the pressure plate has a screw hole inside, and a motor is installed at one end of the guide rail. The output end of the motor has a screw threaded into the screw hole. The motor drives the screw to rotate, and the screw rotates threadedly inside the screw hole, driving the pressure plate to move and press against the coupling ring.

[0009] Preferably, a limit ring is provided at one end of the screw, a second motor is provided at the rear end of the guide rail, a toothed plate is provided at one end of the guide rail, and a gear that meshes with the toothed plate is provided at the output end of the second motor. The limit ring prevents the screw hole from disengaging from the screw, and the second motor drives the gear to rotate, pushing the slider to move, so that the mating ring inside the slider can be slidably adjusted.

[0010] Preferably, one end of the guide rail has a travel groove, the toothed plate is slidably installed inside the travel groove, one end of each connecting tube is provided with a tapered tube, and one end of the tapered tube is rotatably mounted with ball bearings arranged in a ring array. A sealing gasket is provided at the opening of the extrusion tube. The toothed plate is slidably guided inside the travel groove, the tapered tube facilitates the insertion and installation of the connecting tube and the extrusion tube, and the ball bearings improve the stability of the connection and reduce friction and resistance during extrusion and rolling on the inner wall of the guide rail.

[0011] Preferably, an electromagnetic brake is fitted onto the outer side of the second output end of the motor, and bolts are rotatably installed between the docking ring and the support ring. The electromagnetic brake locks the second output end of the motor to prevent it from rotating freely, and the docking ring and the support ring are fixed together by bolts.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model extrusion tube is used to transport hot-melt ABS resin. It is transported through the die of the connecting tube and extruded into a specific shape through the specific die shape. The connecting tubes are installed inside the slider and are evenly distributed. The evenly distributed connecting tubes are adjusted and fixed in position by the longitudinal drive component and the holding structure. By pre-installing the commonly used connecting tubes inside the slider, the shape of the extruded ABS resin can be easily adjusted when needed. Since the die of the connecting tube determines the shape of the extruded ABS resin, the difficulty of changing the connecting tube is reduced, downtime is reduced, and the technical requirements of the change operation are reduced.

[0020] 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.

[0021] like Figures 1-5 As shown, the present invention proposes a multifunctional ABS resin melt extrusion device, including a guide rail 1, a connecting pipe 2, a slider 3, an extrusion pipe 6, a motor 13 and a motor 2 18. The slider 3 is slidably installed inside the guide rail 1. The slider 3 has equally spaced stroke openings 21 inside. The center of the guide rail 1 has a stroke opening 21. One end of the guide rail 1 is provided with an extrusion pipe 6 corresponding to the stroke opening 21. The connecting pipe 2 is slidably inserted into each stroke opening 21 inside the slider 3. A support ring 8 is provided on one side of the slider 3. A docking ring 9 is provided on one side of the support ring 8 and sleeved on the outer wall of the connecting pipe 2. One end of the connecting pipe 2 is provided with a die opening 7 of different specifications. A pressure plate 12 is symmetrically distributed on one side of the support ring 8.

[0022] The support ring 8 and the slider 3 are provided with springs 11 arranged in a ring array at one end;

[0023] A sliding sleeve 15 is embedded inside the pressure plate 12, and a guide rod 16, one end of which is connected to the guide rail 1, is slidably inserted inside the sliding sleeve 15.

[0024] The pressure plate 12 has a screw hole inside, and a motor 13 is provided at one end of the guide rail 1. The output end of the motor 13 is provided with a screw 14 that is threaded into the screw hole.

[0025] A limit ring 17 is provided at one end of the screw 14, a motor 18 is provided at the rear end of the guide rail 1, a toothed plate 5 is provided at one end of the guide rail 1, and a gear 19 that meshes with the toothed plate 5 is provided at the output end of the motor 18.

[0026] One end of the guide rail 1 is provided with a stroke groove 4, the toothed plate 5 is slidably installed inside the stroke groove 4, one end of the connecting pipe 2 is provided with a tapered tube 22, one end of the tapered tube 22 is rotatably installed with balls 23 distributed in a ring array, and a sealing gasket is provided at the opening of the extrusion tube 6.

[0027] An electromagnetic brake 20 is sleeved on the outside of the output end of motor 218, and a bolt 10 is rotatably installed between the docking ring 9 and the support ring 8.

[0028] Based on the implementation steps of Embodiment 1: The support ring 8 is elastically connected to the slider 3 by 6-8 springs 11 distributed in a ring array, providing buffer support for the docking ring 9 and the connecting tube 2. When the pressure plate 12 pushes the docking ring 9 to dock the connecting tube 2 with the extrusion tube 6, the springs 11 can compensate for the small positional deviation during the docking process through elastic deformation, ensuring the coaxiality of the connecting tube 2 and the extrusion tube 6. At the same time, when the die 7 is switched, the springs 11 can be stretched, so that the tapered tube 22 is located inside the guide rail 1 and slides inside the guide rail 1 through the ball bearings 23, avoiding wear of the connecting tube 2 or the extrusion tube 6 caused by rigid collision.

[0029] The support ring 8 is made of 45 steel with heat treatment, which has sufficient rigidity to support the connecting pipe 2. The spring 11 is made of 65Mn spring 11 steel with a stable elastic coefficient and adjustable compression, which solves the problem of poor sealing caused by position deviation in traditional rigid connecting pipe 2. The buffering effect of the spring 11 makes the contact pressure between the connecting pipe 2 and the extrusion pipe 6 uniform, reduces the vibration transmission during equipment operation, and extends the service life of the connecting pipe 2 and the die 7. The pressure plate 12 is a driving component. It slides along the guide rod 16 through the sliding sleeve 15 to accurately push the support ring 8 and the connecting pipe 2 to move towards the extrusion pipe 6, so as to achieve a tight fit between the connecting pipe 2 and the extrusion pipe 6. The cooperation between the sliding sleeve 15 and the guide rod 16 ensures that the moving direction of the pressure plate 12 is parallel to the axis of the extrusion pipe 6, avoiding deformation of the connecting pipe 2 caused by lateral force during docking.

[0030] The pressure plate 12 is made of Q235 steel plate with a rust-proof paint finish and sufficient strength to withstand driving pressure. The sliding sleeve 15 is made of tin bronze, which has excellent self-lubricating properties and reduces sliding resistance when it cooperates with the guide rod 16. The guide rod 16 is made of 45# steel with chrome plating, which is wear-resistant and rust-proof, ensuring long-term sliding without jamming. The rigid guide structure ensures docking accuracy and avoids errors caused by manual calibration. The low-friction cooperation between the sliding sleeve 15 and the guide rod 16 makes the pressure plate 12 move smoothly, reducing the impact force during docking and protecting the edge of the die 7. The motor 13 is a servo motor with a power of 0.75-1.5kW, which drives the screw 14 to rotate. The screw 14 is threaded with the screw hole of the pressure plate 12, converting the rotational motion into the linear motion of the pressure plate 12, realizing the automatic clamping or loosening of the connecting pipe 2 and the extrusion pipe 6. Through the precise control of the servo motor, the clamping force can be adjusted to adapt to the sealing requirements of different specifications of the connecting pipe 2.

[0031] The screw 14 is made of 40Cr alloy steel, surface hardened, with a thread precision of grade 7 to ensure a stable fit with the screw hole. A wear-resistant steel sleeve is inlaid on the inner wall of the screw hole to improve thread wear resistance and prevent stripping after long-term use. This replaces the traditional manual tightening of the bolt 10, automating the tightening process and ensuring uniform and controllable pressure. This solves the problems of "leakage due to excessive looseness" or "deformation due to excessive tightness" caused by manual operation. The servo motor can accurately memorize the tightening position, ensuring consistent pressure each time the connecting pipe 2 is replaced, improving sealing reliability. The limit ring 17 prevents the screw 14 from disengaging from the screw hole, ensuring equipment safety. The motor 18 drives the gear 19 to mesh with the toothed plate 5, causing the slider 3 to slide along the guide rail 1, realizing the switching of different specifications of connecting pipe 2 (die 7). The transmission precision of the toothed plate 5 and gear 19 ensures that the axis of the connecting pipe 2 to be switched coincides with the axis of the extrusion tube 6, eliminating the need for secondary calibration. Ring 17 is made of 304 stainless steel and welded to the end of screw 14. It is rust-resistant and has high strength. Gear 19 and tooth plate 5 are made of 20CrMnTi carburized and quenched, with a tooth surface precision of grade 6. The transmission is smooth and impact-free. Motor 18 is equipped with a high-precision encoder to ensure the positioning accuracy of slider 3 and realize the automated switching of connecting pipe 2. Compared with the traditional manual replacement (1-2 hours), the efficiency is improved. The high positioning accuracy of gear 19 rack and pinion transmission ensures that production can be started without debugging after the die 7 is switched, reducing waste. Stroke groove 4 provides sliding guide for tooth plate 5 to ensure stable meshing between gear 19 and tooth plate 5. Tapered tube 22 makes the docking of connecting pipe 2 and extrusion tube 6 smoother and reduces insertion resistance. Ball bearings 23 are distributed at the end of tapered tube 22. They roll and contact the inner wall of extrusion tube 6 during docking, reducing friction and assisting in centering. The sealing gasket is compressed during docking to achieve the sealing of the melt.

[0032] The tapered tube 22 is made of 304 stainless steel with a polished surface to avoid scratching the inner wall of the extrusion tube 6. The ball bearing 23 is made of GCr15 bearing steel with a precision grade of G10 and a smooth, burr-free surface. The sealing gasket is made of high-temperature resistant fluororubber, which is resistant to ABS melt corrosion. The fit between the tapered tube 22 and the ball bearing 23 reduces the difficulty of docking and makes automatic switching smoother. The fluororubber sealing gasket solves the problem of easy leakage of traditional metal surface seals, and the melt leakage rate is close to 0. At the same time, it avoids the aging damage of the seal to the seal by the high-temperature melt. The electromagnetic brake 20 locks the output shaft when the motor 2 18 stops working to prevent the slider 3 from being displaced due to vibration or gravity and ensures the stability of the position of the connecting tube 2. The bolt 10 is used to fix the docking ring 9 and the support ring 8 to prevent the connecting tube 2 from rotating or moving axially under the extrusion pressure. The electromagnetic brake 20 is a DC electromagnetic brake with a fast response time and is adapted to the power requirements of the motor 2 18. The bolt 10 is a high-strength bolt with a galvanized surface for rust prevention to ensure connection strength.

[0033] The instant locking function of the electromagnetic brake 20 enhances equipment safety and prevents misalignment of the die 7 caused by the displacement of the slider 3 during production. The bolt 10 ensures that the connecting pipe 2 does not loosen under the action of high-pressure melt, thus ensuring the stability of product dimensions. The optimized structures of this multi-functional ABS resin melt extrusion device solve the problems of long die replacement time, low precision, and high labor intensity in traditional die replacement through the combination of automated drive, precise guidance, and reliable sealing. The materials of each structural component are adapted to the working conditions of high temperature, high pressure, and high frequency switching, ensuring that the equipment can complete the die 7 switching within minutes and that the product qualification rate is high after replacement, significantly improving the production efficiency and quality stability of various ABS products.
