Description

Technical Field

[0001] This utility model relates to the technical field of polystyrene production equipment, and in particular to a polystyrene raw material production molding device. Background Technology

[0002] Polystyrene, a high-performance and widely used thermoplastic, plays a crucial role in modern industrial production. From disposable tableware and packaging materials in daily life to insulation boards in the construction industry and casings for electronic appliances, polystyrene meets the diverse needs of many industries thanks to its excellent processing performance and physicochemical properties. In the polystyrene production process, the raw material conveying system, as the initial stage of production, directly affects the stability and product quality of subsequent plasticizing, molding, and other processes.

[0003] Most existing polystyrene raw material conveying systems use traditional screw conveyors. While this method is simple in structure and low in cost, in actual use, it has been found that raw materials tend to accumulate locally within the screw grooves, leading to significant fluctuations in the conveying volume. This results in inconsistent amounts of raw material entering the heating and plasticizing system, causing uneven plasticization and ultimately affecting product quality. Furthermore, raw material blockage is a prominent issue in existing polystyrene raw material conveying systems. During storage and transportation, polystyrene raw materials may clump due to moisture, compression, or other factors. When these clumps enter the conveying system, they easily become stuck at the hopper outlet, gaps in the screw conveyor, or bends, causing conveying interruptions. To clear these blockages, production personnel must frequently stop the machine, which not only reduces production efficiency and increases labor intensity but may also affect product quality stability due to fluctuations in process parameters during shutdowns and restarts. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that raw materials tend to accumulate locally in the spiral groove, which reduces production efficiency and increases the intensity of manual labor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a polystyrene raw material production and molding device, comprising: a base; a mounting frame welded to the upper end of the base; a feeding assembly disposed on the top of the mounting frame, the lower end of which penetrates through the top of the mounting frame and extends downward; a crushing assembly disposed below the feeding assembly, the upper end of which is provided with a connecting cavity, which can form a raw material flow channel with the feeding assembly; and a screw conveyor disposed at the lower end of the crushing assembly, the upper end of which is provided with a feed chute, which is disposed at the lower port of the crushing assembly.

[0006] The technical effect of adopting the above-mentioned further solution is that: the polystyrene raw material is conveyed by the feeding component, crushed by the crushing component, and then conveyed by the screw conveyor, realizing the continuous processing of the raw material from conveying, crushing to conveying, efficiently completing the pre-processing and molding preparation of the polystyrene raw material, and improving the continuity and efficiency of production.

[0007] In a preferred embodiment, the feeding assembly includes: a mixing chamber disposed at the upper end of the mounting frame, the lower end of which extends downward through the top of the mounting frame and is fixedly connected to a first feeding port; two mixing shafts disposed inside the mixing chamber, with multiple mixing columns welded to their exterior; a first pulley with a second pulley disposed on one side, the two being fixedly connected to the ends of the two mixing shafts respectively, and the two being connected by a transmission belt; and a first motor disposed on one side of the second pulley, the output end of which is connected to a connecting shaft, the other end of which is fixedly connected to the second pulley.

[0008] The technical effect of adopting the above-mentioned further solution is that the first motor drives the two stirring shafts to rotate via the pulley and transmission belt, thereby causing the stirring column to stir the polystyrene raw material in the stirring chamber, achieving uniform feeding of the raw material and ensuring smooth subsequent processing.

[0009] In a preferred embodiment, the feeding assembly further includes: guide blocks, fixedly connected to both sides of the mixing chamber, and both ends of which are fixedly connected to the top of the mounting frame; guide posts, disposed below the two guide blocks; a stop block, disposed at the lower end of the first feeding port, with both ends movably disposed on the guide posts, and a lead screw disposed in the middle, which allows the stop block to move along the axis of the lead screw; and a second motor, connected to one end of the lead screw.

[0010] The technical effect of adopting the above-mentioned further solution is that the second motor drives the lead screw, which moves the stop on the guide column to control the opening and closing of the first discharge port. Combined with the original mixing and feeding function, it realizes precise control of the raw material conveying amount, further ensures uniform and stable feeding, and improves the overall process controllability.

[0011] In a preferred embodiment, the crushing assembly includes: a crushing chamber disposed at the lower port of the communicating chamber; two crushing rollers, one of which is connected to a first rotating shaft; and a second discharge port disposed through the bottom of the crushing chamber.

[0012] The technical effect of adopting the above-mentioned further solution is that: two crushing rollers with first rotating shafts crush the raw material in the crushing chamber, and the crushed raw material is output through the second discharge port, which receives the raw material conveyed by the feeding component and completes the crushing process, providing raw material of suitable particle size for subsequent processing and ensuring the pretreatment effect of raw material before molding.

[0013] In a preferred embodiment, the crushing assembly further includes: a driven gear, one side of which is meshed with a transmission gear, and the two are respectively fixedly connected to the ends of two first rotating shafts; a third motor, which is disposed on one side of the transmission gear, and its output end is connected to a second rotating shaft, the second rotating shaft being fixedly connected to the transmission gear.

[0014] The technical effect of adopting the above-mentioned further solution is that the third motor drives the transmission gear through the second rotating shaft, meshes with the driven gear, and makes the two crushing rollers rotate, efficiently crushing the raw materials, which are then output through the second discharge port, enhancing the crushing power and efficiency, ensuring that the raw materials are fully crushed, and adapting to the needs of subsequent processing.

[0015] In a preferred embodiment, the feeding assembly further includes a limiting groove, which is fixedly connected to both sides of the stop block and is engaged with the outside of the guide block.

[0016] The technical effect of adopting the above-mentioned further solution is that the limiting groove is set outside the guide block, and in conjunction with the movement of the stop block on the guide column, it restricts the offset of the stop block, making the opening and closing of the first discharge port more stable and precise, enhancing the control accuracy of raw material conveying, and ensuring the uniformity of material feeding and the smoothness of subsequent processes.

[0017] In a preferred embodiment, a fourth motor is provided at one end of the screw conveyor.

[0018] The technical effect of adopting the above-mentioned further solution is to provide power for the screw conveyor.

[0019] In a preferred embodiment, a material collection pipe is provided through one side of the screw conveyor.

[0020] The technical effect of adopting the above-mentioned further solution is that the collecting pipe can centrally discharge the crushed polystyrene raw materials it transports.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] 1. This utility model effectively avoids localized accumulation of raw materials within the spiral groove through the precise control design of the feeding assembly. In the feeding assembly, a second motor drives a lead screw to move a stop block along a guide column, precisely and regularly controlling the opening and closing degree of the first feeding port. The feeding speed can be flexibly adjusted according to actual production needs. This ensures a uniform and stable flow of raw materials entering the screw conveyor, reducing localized accumulation within the spiral groove caused by large influxes of raw materials. This guarantees the continuity of the production process, improves overall production efficiency, and reduces the labor intensity of frequently handling raw material accumulation issues manually.

[0023] 2. This utility model further optimizes the raw material conveying process through the efficient crushing function of the crushing component. Two crushing rollers rotate in opposite directions under the drive of a third motor. Through the meshing of the driven gear and the transmission gear, the polystyrene raw material is fully crushed into suitable particle sizes. The finely crushed and uniformly distributed raw material enters the screw conveyor and is more easily and smoothly conveyed under the propulsion of the screw blades, preventing accumulation and effectively reducing the occurrence of blockages. This not only significantly improves the working efficiency of the screw conveyor but also reduces the workload of manually cleaning blockages and unblocking the screw grooves, lowering labor intensity and increasing the production efficiency of the device.

[0030] 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.

[0031] Please see Figure 1-4 This utility model provides a technical solution: a polystyrene raw material production and molding device, characterized in that it includes a base 1, a mounting frame 2, a feeding assembly, a crushing assembly and a screw conveyor 25;

[0032] Mounting bracket 2 is firmly fixed to the upper surface of base 1 by welding, providing a stable support structure for the entire device;

[0033] The feeding assembly is installed on the top of the mounting frame 2, and its lower end extends downward through the top of the mounting frame 2.

[0034] The crushing component is located below the feeding component. The connecting cavity 30 at the upper end of the crushing component cooperates with the feeding component to form a continuous raw material flow channel so that the raw material can pass through smoothly.

[0035] The screw conveyor 25 is located at the lower end of the crushing component. The upper end of the screw conveyor 25 is equipped with a feed chute 26. The feed chute 26 is precisely set at the lower port of the crushing component to ensure that the crushed raw material can directly enter the screw conveyor 25 for conveying.

[0036] Through the orderly coordination of various components, a continuous processing procedure for polystyrene raw materials from feeding to transportation is achieved.

[0037] like Figure 1-4 As shown, the feeding assembly includes a mixing chamber 3 fixedly installed on the upper end of the mounting frame 2, the lower end of which passes through the top of the mounting frame 2 and is fixedly connected to the first feeding port 10;

[0038] Two stirring shafts 4 are installed in parallel inside the stirring chamber 3, and multiple stirring columns 5 are uniformly welded to the outside of the stirring shafts 4 for stirring and mixing the raw materials;

[0039] The first pulley 6 and the second pulley 7 are respectively fixedly sleeved on the ends of the two stirring shafts 4, and the two are connected by a transmission belt 29 to ensure that the two stirring shafts 4 rotate synchronously.

[0041] The guide block 11 is fixedly connected to both sides of the mixing chamber 3, and its two ends are fixedly connected to the top of the mounting frame 2, which serves to stabilize the mixing chamber 3.

[0042] The guide post 12 is located below the two guide blocks 11, and the stop block 13 is located at the lower end of the first discharge port 10. The two ends of the stop block 13 are movably sleeved on the guide post 12, and the middle part is connected to the lead screw 14. Under the drive of the lead screw 14, the stop block 13 can move along the axis of the lead screw 14, thereby realizing the opening and closing control of the first discharge port 10.

[0043] Among them, the two sides of the stop block 13 are provided with limit grooves 16, and the limit grooves 16 cooperate with the guide block 11. While further restricting the stop block 13, it can also ensure the stability of the device when the stop block 13 blocks the first discharge port 10.

[0044] The second motor 15 is connected to one end of the lead screw 14, providing power for the rotation of the lead screw 14. Through this structure, the feeding assembly can fully mix the raw materials and flexibly control the feeding speed.

[0045] like Figure 1-4 As shown, the crushing assembly includes a crushing chamber 17, a crushing roller 18, a first rotating shaft 19, a second feeding port 24, a driven gear 20, a transmission gear 21, a third motor 22, and a second rotating shaft 23.

[0046] The crushing chamber 17 is located at the lower port of the connecting chamber 30 and is used to accommodate raw materials for crushing.

[0047] The two crushing rollers 18 are connected in the middle by a first rotating shaft 19, and the crushing rollers 18 cooperate with each other to crush the raw materials;

[0048] The second discharge port 24 is set through the bottom of the crushing chamber 17 to facilitate the discharge of the crushed raw material;

[0049] Driven gear 20 and transmission gear 21 are respectively fixedly sleeved on the ends of the two first rotating shafts 19, and the two mesh with each other to ensure that the two crushing rollers 18 rotate in opposite directions.

[0050] The third motor 22 is located on one side of the transmission gear 21, and its output end is fixedly connected to the transmission gear 21 through the second rotating shaft 23 to provide power for the rotation of the crushing roller 18.

[0051] By setting up this crushing component, raw materials can be efficiently crushed into suitable particle sizes, facilitating subsequent conveying and other processes.

[0052] like Figure 1-4 As shown, a fourth motor 27 is provided at one end of the screw conveyor 25, and the fourth motor 27 provides rotational power for the screw conveyor 25;

[0053] A material collection pipe 28 is provided through one side of the screw conveyor 25 for collecting the conveyed raw materials.

[0054] The screw conveyor 25, together with the fourth motor 27 and the collection pipe 28, enables efficient conveying and collection of the crushed raw materials.

[0055] Working principle: This equipment is a polystyrene raw material production and molding device. In use, the polystyrene raw material is first fed into the feeding assembly at the top of the mounting frame 2. At this time, the first motor 9 is started. The first motor 9 drives the second pulley 7 to rotate via the connecting shaft 8. The second pulley 7 then drives the first pulley 6 via the transmission belt 29, causing the two stirring shafts 4 to rotate synchronously. Multiple stirring columns 5 installed outside the stirring shafts 4 then thoroughly stir and mix the raw material, ensuring its uniformity.

[0056] After mixing is completed, the second motor 15 is started. The second motor 15 drives the lead screw 14 to rotate. The lead screw 14 drives the stop block 13 to move along the guide column 12 in the direction of the lead screw 14 axis. When the stop block 13 moves, the first discharge port 10 opens, and the raw material falls down into the communicating cavity 30 of the crushing component through the first discharge port 10, and then enters the crushing cavity 17. In this way, by controlling the working frequency of the second motor 15, the regular feeding of the feeding component can be achieved, thereby improving the crushing and conveying effect of the device.

[0057] Inside the crushing chamber 17, the third motor 22 is started. The third motor 22 drives the transmission gear 21 to rotate through the second rotating shaft 23. The transmission gear 21 meshes with the driven gear 20, causing the two crushing rollers 18 to rotate in opposite directions, crushing the raw material falling into the crushing chamber 17. The crushed raw material is discharged through the second discharge port 24, which is set at the bottom of the crushing chamber 17.

[0058] After the crushed raw material is discharged from the second discharge port 24, it falls directly into the feed trough 26 at the upper end of the screw conveyor 25. At this time, the fourth motor 27 is started, and the fourth motor 27 drives the screw conveyor 25 to run, conveying the raw material entering the feed trough 26 along the screw conveyor 25, and collecting and outputting it through the collection pipe 28 set through one side, thus completing the entire operation process of polystyrene raw material from mixing, feeding, crushing to conveying.

[0059] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
