Description

Technical Field

[0001] This invention belongs to the field of batching device technology, and more specifically, it is a batching device for polystyrene production. Background Technology

[0002] A polystyrene production batching device is a device used in the production and processing of polystyrene materials to mix and batch the raw materials. It can mix and proportion the raw materials and additives of polystyrene to facilitate subsequent heating operations. Polystyrene is a polymer synthesized from styrene monomers through a free radical addition polymerization reaction. It is a colorless and transparent thermoplastic with a glass transition temperature above 100°C.

[0003] Patent document CN213919077U discloses a batching device for polystyrene production, including a mixing tank. A first material extractor and a second material extractor are respectively attached to both sides of the mixing tank. The batching material is stored through a storage pipe. A rotating material-pulling roller moves and blocks the material within the storage pipe, allowing operators to mix and store large quantities of material. This enables continuous and uninterrupted mixing of raw materials and batching materials, effectively improving the device's efficiency. The first and second material extractors replace manual labor for material extraction and discharge, eliminating the need for manual handling during material loading and unloading, and also reducing the workload of workers. Furthermore, the material extraction method improves the device's loading and unloading efficiency.

[0004] The aforementioned device has certain shortcomings in its use. Polystyrene raw materials and additives are typically in granular and powder form, which easily generates dust during the mixing and addition process. This causes the powdered additives to disperse into the air, and the device lacks a dust-prevention structure, resulting in poor performance. Furthermore, the device lacks an internal cleaning structure. After prolonged use, a certain amount of raw material tends to adhere to the inner wall of the mixing tank, requiring regular cleaning by the user. Residual raw material can affect the accuracy of the polystyrene material proportions, leading to defects in the processed polystyrene. Additionally, the device lacks a telescopic adjustment structure, making it impossible to adjust the upper limit of its mixing capacity according to usage needs, thus reducing its operational flexibility. Summary of the Invention

[0005] The purpose of this invention is to provide a polystyrene production batching device that can solve existing problems.

[0006] The problem solved by this invention is:

[0007] 1. The raw materials and additives of polystyrene are usually in granular and powder form. When they are added, dust is easily generated, causing the powdered additives to be dispersed in the air. The above-mentioned device does not have a dust prevention structure for adding materials, resulting in poor performance.

[0008] 2. The above-mentioned device does not have an internal wall cleaning structure. After long-term use, a certain amount of raw material will easily adhere to the inner wall of its mixing box, requiring users to clean it regularly. The residual raw material will affect the proportioning accuracy of polystyrene material, causing defects in the processed polystyrene material.

[0009] 3. The above-mentioned device does not have a telescopic adjustment structure, and its upper limit of dispensing capacity cannot be adjusted, which makes it impossible to adjust the dispensing capacity arbitrarily according to the usage requirements, thus reducing its flexibility in use.

[0010] The objective of this invention can be achieved through the following technical solutions:

[0011] A polystyrene production batching device includes a receiving box and a mixing box. The mixing box is fixedly installed on the upper end of the receiving box. The upper part of the mixing box is respectively provided with a first feeding bucket, a second feeding bucket, and a third feeding bucket. The third feeding bucket is fixedly installed on one side of the second feeding bucket, and the first feeding bucket is fixedly installed on the other side of the second feeding bucket. The upper ends of the first, second, and third feeding buckets are all movably fitted with lifting sleeves, and the lower ends of the first, second, and third feeding buckets are all movably installed with docking rings. The upper outer surface of the mixing box is fixedly installed with a docking seat for use with the docking rings. A mixing rod is movably installed at the middle position of the inner side of the mixing box, and a first scraping frame and a second scraping frame are movably installed on both sides of the mixing rod, respectively.

[0012] As a further technical solution of the present invention, stirring rods for connecting with the first scraper frame and the second scraper frame are fixedly installed on both outer surfaces of the mixing rod. The inner sides of the first scraper frame and the second scraper frame are hollow structures. The hollow structure design of the first scraper frame and the second scraper frame can reduce the resistance of the first scraper frame and the second scraper frame when they rotate. When the first scraper frame and the second scraper frame rotate, they can clean the raw materials adhering to the side of the mixing box.

[0013] As a further technical solution of the present invention, the sides of the first scraper frame and the second scraper frame are both inclined structures. The outer surfaces of the first scraper frame and the second scraper frame are fixedly installed with docking rod heads for use with stirring rods. The docking rod heads and the stirring rods are connected by docking sleeves. By using the docking sleeves, a movable adjustment structure is formed between the docking rod heads and the stirring rods. When the first scraper frame and the second scraper frame are rotating to clean the material, the positions of the first scraper frame and the second scraper frame can be flexibly adjusted to avoid jamming of the first scraper frame and the second scraper frame.

[0014] As a further technical solution of the present invention, a limiting collar is fixedly installed at the ends of both the stirring rod and the docking rod head. A spring is provided between the stirring rod and the docking rod head on the inner side of the docking sleeve. The spring provides an elastic structure between the stirring rod and the docking rod head, allowing the first scraping frame and the second scraping frame on the docking rod head to fit tightly against the inner wall of the mixing box, thereby improving the performance of the first scraping frame and the second scraping frame. Furthermore, the limiting collar prevents the stirring rod and the docking rod head from falling out of the docking sleeve.

[0015] As a further technical solution of the present invention, a mixing motor is provided at the lower part of the mixing rod. The output shaft of the mixing motor and the mixing rod are connected by a fixed clamp. The user starts the mixing motor, which drives the mixing rod to rotate. The mixing rod drives the stirring rod to rotate, thereby completing the mixing operation of polystyrene material raw materials and additives in the mixing box.

[0016] As a further technical solution of the present invention, the upper ends of the first feeding barrel, the second feeding barrel, and the third feeding barrel are all fixedly installed with fixing rings for use with the lifting sleeve, and the inner side of the fixing rings is provided with fastening bolts. One end of the lifting sleeve is fixedly installed with a second limiting ring. By pulling the lifting sleeve, the user can adjust the working height of the first feeding barrel, the second feeding barrel, and the third feeding barrel, so that the first feeding barrel, the second feeding barrel, and the third feeding barrel can hold polystyrene production materials of any volume. At the same time, the user can lock and fix the lifting sleeve after it is pulled out by rotating the fastening bolt of the fixing ring.

[0017] As a further technical solution of the present invention, a discharge nozzle is fixedly installed at the lower end of the first feeding barrel, the second feeding barrel, and the third feeding barrel. A feeding motor is installed on the lower part of one side of the first feeding barrel, the second feeding barrel, and the third feeding barrel. A material feeding plate is installed on the output shaft of the feeding motor, and the material feeding plate is movably installed inside the discharge nozzle. The user starts the feeding motor, which drives the material feeding plate to rotate, thereby completing the raw material output operation of the first feeding barrel, the second feeding barrel, and the third feeding barrel at the discharge nozzle.

[0018] As a further technical solution of the present invention, a telescopic sleeve is fixedly installed on the upper outer surface of the docking ring, and the telescopic sleeve is movably installed on the lower inner side of the discharge nozzle. A first limiting ring is fixedly installed on the upper outer surface of the telescopic sleeve, and a damping sleeve is sleeved on the outer surface of the telescopic sleeve. The damping sleeve is fixedly installed on the inner side of the discharge nozzle. By using the setting of the damping sleeve, the friction of the surface of the telescopic sleeve can be increased, which plays an auxiliary fixing role in the extension or retraction of the telescopic sleeve. When the telescopic sleeve is pulled out, the telescopic sleeve and the docking seat of the mixing box are docked together. When the first feeding bucket, the second feeding bucket and the third feeding bucket are discharging materials, dust can be effectively avoided.

[0019] As a further technical solution of the present invention, the lower part of the mixing box is provided with a receiving box, and the mixing box and the receiving box are connected by a material pipe. The upper end of the receiving box is fixedly installed with a fixed frame, and two sets of support frames for supporting the first feeding bucket, the second feeding bucket and the third feeding bucket are fixedly installed on the side of the fixed frame. A vibrator is fixedly installed on the side of one set of support frames.

[0020] The beneficial effects of this invention are:

[0021] 1. By setting up telescopic sleeves and docking rings, when using this polystyrene production batching device, the user utilizes the telescopic sleeves to form a telescopic docking discharge structure at the bottom of the first, second, and third feeding buckets. During use, the user pulls down the telescopic sleeve, and a damping sleeve is fixedly installed inside the discharge nozzle. The damping sleeve increases the friction on the surface of the telescopic sleeve, providing auxiliary fixation for the pulled-out or retracted sleeve. Pulling out the telescopic sleeve allows the docking ring of the telescopic sleeve to engage with the docking seat of the mixing box. The interconnected design effectively prevents dust generation during the discharge operation of the first, second, and third feeding hoppers. This allows the raw materials from these hoppers to be directly introduced into the mixing tank via the telescopic sleeve, avoiding dust generation during material transport. Furthermore, the connection between the connecting ring and the connecting seat effectively improves the sealing between the telescopic sleeve and the mixing tank. By using the telescopic sleeve in conjunction with the connecting ring, this polystyrene production batching device possesses a dust-proof feeding structure, enhancing its performance.

[0022] 2. By setting up a first scraper frame and a second scraper frame, when using this polystyrene production batching device, the user introduces the raw materials and additives into the first, second, and third feeding buckets respectively. After the telescopic sleeve completes the docking operation, the user starts the conveying motor, which drives the material-pulling plate to rotate, thereby completing the raw material output operation of the first, second, and third feeding buckets at the discharge nozzle. The raw materials and additives are introduced into the mixing tank in proportion. The user starts the mixing motor, which drives the mixing rod to rotate, which in turn drives the stirring rod to rotate, thereby completing the mixing operation of polystyrene material raw materials and additives in the mixing tank. The stirring rod simultaneously drives the first and second scraper frames to rotate, completing the cleaning operation of the inner wall of the mixing tank. Utilizing the docking sleeve, the docking rod head and the stirring rod are connected. An adjustable structure is formed between the first and second scraper frames. During the rotational cleaning operation, the positions of the first and second scraper frames can be flexibly adjusted to prevent jamming. The spring design provides elasticity between the stirring rod and the docking rod head, allowing the first and second scraper frames on the docking rod head to adhere tightly to the inner wall of the mixing tank, improving their performance. Furthermore, in case of jamming, the first and second scraper frames can overcome any obstructions. The limiting collar prevents the stirring rod and docking rod head from detaching from the docking sleeve. By incorporating the first and second scraper frames, this polystyrene production batching device features a synchronous cleaning structure, keeping the inner wall of the mixing tank clean, preventing raw material residue, and improving batching accuracy.

[0023] 3. By setting up lifting sleeves, the first, second, and third feeding barrels of this polystyrene production batching device have telescopic adjustment structures. Users can adjust the height of the first, second, and third feeding barrels by pulling the lifting sleeves, allowing any volume of polystyrene production materials to be contained in them. At the same time, users can lock the lifting sleeves after they are pulled out by rotating the fastening bolts of the fixing rings. The lifting sleeves improve the flexibility of the polystyrene production batching device during use. Attached Figure Description

[0031] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0032] like Figure 1-5 As shown, a polystyrene production batching device includes a receiving box 1 and a mixing box 3. The mixing box 3 is fixedly installed on the upper end of the receiving box 1. The upper part of the mixing box 3 is respectively provided with a first feeding bucket 8, a second feeding bucket 10 and a third feeding bucket 11. The third feeding bucket 11 is fixedly installed on one side of the second feeding bucket 10, and the first feeding bucket 8 is fixedly installed on the other side of the second feeding bucket 10. The upper ends of the first feeding bucket 8, the second feeding bucket 10 and the third feeding bucket 11 are all movably sleeved with lifting sleeves 17, and the lower ends of the first feeding bucket 8, the second feeding bucket 10 and the third feeding bucket 11 are all movably installed with docking rings 5. The upper outer surface of the mixing box 3 is fixedly installed with a docking seat 4 that cooperates with the docking rings 5. The mixing rod 2 is movably installed in the middle of the inner side of the mixing box 3, and the first scraper frame 24 and the second scraper frame 25 are movably installed on both sides of the mixing rod 2, respectively.

[0033] Both outer surfaces of the mixing rod 2 are fixedly equipped with stirring rods 21 for connecting the first scraper frame 24 and the second scraper frame 25. The inner sides of the first scraper frame 24 and the second scraper frame 25 are hollow. The hollow structure design of the first scraper frame 24 and the second scraper frame 25 can reduce the resistance of the first scraper frame 24 and the second scraper frame 25 when they rotate. When the first scraper frame 24 and the second scraper frame 25 rotate, they can clean the raw materials adhering to the side of the mixing box 3.

[0034] Both the first scraper frame 24 and the second scraper frame 25 have beveled sides. The outer surfaces of both the first scraper frame 24 and the second scraper frame 25 are fixedly fitted with docking rod heads 23 for use with the stirring rod 21. The docking rod heads 23 and the stirring rod 21 are connected by docking sleeves 22. The docking sleeves 22 allow for a movable adjustment structure between the docking rod heads 23 and the stirring rod 21. When the first scraper frame 24 and the second scraper frame 25 are rotating to clean the material, their positions can be flexibly adjusted to prevent them from getting stuck.

[0035] Limiting collars 28 are fixedly installed at the ends of the stirring rod 21 and the docking rod head 23. A spring 27 is provided between the stirring rod 21 and the docking rod head 23 on the inner side of the docking sleeve 22. The spring 27 provides an elastic structure between the stirring rod 21 and the docking rod head 23, allowing the first scraper frame 24 and the second scraper frame 25 on the docking rod head 23 to fit tightly against the inner wall of the mixing box 3, thereby improving the performance of the first scraper frame 24 and the second scraper frame 25. Furthermore, the limiting collar 28 prevents the stirring rod 21 and the docking rod head 23 from falling out of the docking sleeve 22.

[0036] The lower part of the mixing rod 2 is equipped with a mixing motor 20. The output shaft of the mixing motor 20 and the mixing rod 2 are connected by a fixed sleeve 26. The user starts the mixing motor 20, which drives the mixing rod 2 to rotate. The mixing rod 2 drives the stirring rod 21 to rotate, thereby completing the mixing and stirring operation of various polystyrene materials in the mixing box 3.

[0037] The upper ends of the first feeding hopper 8, the second feeding hopper 10, and the third feeding hopper 11 are all fixedly installed with retaining rings 19 that work with the lifting sleeve 17. The inner side of the retaining rings 19 is provided with fastening bolts. One end of the lifting sleeve 17 is fixedly installed with a second limiting ring 18. By pulling the lifting sleeve 17, the user can adjust the working height of the first feeding hopper 8, the second feeding hopper 10, and the third feeding hopper 11, so that any volume of polystyrene production materials can be contained in the first feeding hopper 8, the second feeding hopper 10, and the third feeding hopper 11. At the same time, the user can lock and fix the lifting sleeve 17 after it is pulled out by rotating the fastening bolts of the retaining rings 19.

[0038] The lower ends of the first feeding hopper 8, the second feeding hopper 10, and the third feeding hopper 11 are all fixedly equipped with discharge nozzles 16. A feeding motor 6 is installed on the lower part of one side of each of the first feeding hopper 8, the second feeding hopper 10, and the third feeding hopper 11. A material feeding plate is installed on the output shaft of the feeding motor 6, and the material feeding plate is movably installed inside the discharge nozzle 16. By starting the feeding motor 6, the user causes the feeding motor 6 to drive the material feeding plate to rotate, thereby completing the raw material output operation of the first feeding hopper 8, the second feeding hopper 10, and the third feeding hopper at the discharge nozzle 16.

[0039] A telescopic sleeve 13 is fixedly installed on the upper outer surface of the docking ring 5, and the telescopic sleeve 13 is movably installed on the lower inner side of the discharge nozzle 16. A first limiting ring 14 is fixedly installed on the upper outer surface of the telescopic sleeve 13. A damping sleeve 15 is sleeved on the outer surface of the telescopic sleeve 13 and is fixedly installed on the inner side of the discharge nozzle 16. By using the setting of the damping sleeve 15, the friction of the surface of the telescopic sleeve 13 can be increased, which plays an auxiliary fixing role in the extension or retraction of the telescopic sleeve 13. When the telescopic sleeve 13 is pulled out, the telescopic sleeve 13 and the docking seat 4 of the mixing box 3 are docked together. When the first feeding bucket 8, the second feeding bucket 10 and the third feeding bucket 11 are discharging materials, dust can be effectively avoided.

[0040] The mixing box 3 is provided with a receiving box 1 at the bottom, and the mixing box 3 and the receiving box 1 are connected by a material pipe. A fixed frame 12 is fixedly installed at the upper end of the receiving box 1, and two sets of support frames 7 for supporting the first feeding bucket 8, the second feeding bucket 10 and the third feeding bucket 11 are fixedly installed on the side of the fixed frame 12. A vibrator 9 is fixedly installed on the side of one set of support frames 7.

[0041] This polystyrene production batching device, by setting a telescopic sleeve 13 and a docking retaining ring 5, allows the user to utilize the telescopic sleeve 13 to form a telescopic docking discharge structure at the lower part of the first feeding barrel 8, the second feeding barrel 10, and the third feeding barrel 11. During use, the user pulls down the telescopic sleeve 13, and a damping sleeve 15 is fixedly installed inside the discharge nozzle 16. The damping sleeve 15 increases the friction on the surface of the telescopic sleeve 13, providing auxiliary fixation for the pulled-out or retracted telescopic sleeve 13. When the telescopic sleeve 13 is pulled out, the docking retaining ring 5 and... The docking seats 4 of the mixing tank 3 are connected to each other. When the first feeding tank 8, the second feeding tank 10 and the third feeding tank 11 are discharging materials, dust can be effectively avoided. The raw materials in the first feeding tank 8, the second feeding tank 10 and the third feeding tank 11 are directly introduced into the mixing tank 3 through the telescopic sleeve 13, avoiding dust during the material transportation process. Secondly, the docking between the docking ring 5 and the docking seat 4 can effectively improve the sealing between the telescopic sleeve 13 and the mixing tank 3. By setting the telescopic sleeve 13 in conjunction with the docking ring 5, the polystyrene production batching device has a material feeding and dust prevention structure, improving its performance.

[0042] By setting up a first scraper frame 24 and a second scraper frame 25, when using this polystyrene production batching device, the user introduces raw materials and additives into the first feeding bucket 8, the second feeding bucket 10, and the third feeding bucket 11, respectively. After the telescopic sleeve 13 completes the docking operation, the user starts the conveying motor 6, which drives the material feeding plate to rotate, thereby completing the raw material output operation of the first feeding bucket 8, the second feeding bucket 10, and the third feeding bucket 11 at the discharge nozzle 16. The raw materials and additives are introduced into the mixing tank 3 in proportion. The user starts the mixing motor 20, which drives the mixing rod 2 to rotate, which in turn drives the stirring rod 21 to rotate, thereby completing the mixing operation of polystyrene material raw materials and additives in the mixing tank 3. The stirring rod 21 simultaneously drives the first scraper frame 24 and the second scraper frame 25 to rotate, completing the cleaning operation of the inner wall of the mixing tank 3. By using the docking sleeve 22, a connection is formed between the docking rod head 23 and the stirring rod 21. The device features an adjustable structure that allows for flexible adjustment of the positions of the first scraper frame 24 and the second scraper frame 25 during rotational cleaning operations. This prevents the first scraper frame 24 and the second scraper frame 25 from jamming. The spring 27 provides elasticity between the stirring rod 21 and the docking rod head 23, allowing the first scraper frame 24 and the second scraper frame 25 on the docking rod head 23 to adhere tightly to the inner wall of the mixing tank 3, improving their performance. Furthermore, in case of jamming, the first scraper frame 24 and the second scraper frame 25 can overcome any obstructions. The limiting collar 28 prevents the stirring rod 21 and the docking rod head 23 from detaching from the docking sleeve 22. By incorporating the first scraper frame 24 and the second scraper frame 25, the polystyrene production batching device features a synchronous cleaning structure, keeping the inner wall of the mixing tank 3 clean, preventing raw material residue, and improving batching accuracy.

[0043] By setting up the lifting sleeve 17, the first feeding barrel 8, the second feeding barrel 10, and the third feeding barrel 11 all have telescopic adjustment structures when the polystyrene production batching device is in use. By pulling the lifting sleeve 17, the user can adjust the working height of the first feeding barrel 8, the second feeding barrel 10, and the third feeding barrel 11, so that any volume of polystyrene production batching materials can be contained in the first feeding barrel 8, the second feeding barrel 10, and the third feeding barrel 11. At the same time, the user can lock and fix the lifting sleeve 17 after it is pulled out by rotating the fastening bolt of the fixing ring 19. The setting of the lifting sleeve 17 improves the flexibility of the polystyrene production batching device when it is in use.
