Description

Technical Field

[0001] This utility model relates to the field of woven bag technology, and in particular to a drying device for raw materials used in the production of plastic woven bags. Background Technology

[0002] In the production process of plastic woven bags, the drying of raw materials is a crucial step. Plastic granules easily absorb moisture from the air during storage and transportation. The presence of moisture has many negative impacts on the production and quality of plastic woven bags. Therefore, a raw material drying device for plastic woven bag production is needed.

[0003] A drying device for raw materials used in the production of plastic woven bags is a specialized device for removing moisture from plastic granules used in the production of plastic woven bags. It dries the raw materials using specific technologies, including hot air circulation and vacuum suction. Currently, uneven hot air distribution in hot air drying devices can lead to inconsistent drying levels. In large-scale drying equipment, raw materials near the air outlet may be over-dried, while those further away may be under-dried. Existing solutions involve installing multi-directional guide vanes at the hot air inlet to allow the hot air to enter the drying chamber more evenly and distribute the airflow evenly to different areas. However, hot air has a natural tendency to rise. Due to its lower density, even with guide vanes to achieve a relatively uniform initial distribution, the hot air will gradually rise within the drying chamber, resulting in less heat reaching the bottom and causing uneven heating at the bottom. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a drying device for raw materials in the production of plastic woven bags. It aims to improve the problem in the prior art where, due to the low density of hot air, the guide vanes make the initial distribution of hot air relatively uniform, but in the drying chamber, the hot air will still gradually gather upwards, resulting in relatively less heat being obtained at the bottom, thus causing uneven heating at the bottom.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a drying device for raw materials used in the production of plastic woven bags, comprising a fixed base, with rotating rods rotatably mounted on the front and rear sides of the top inner wall of the fixed base, and rollers fixedly connected to the left and right sides of the outer walls of the two rotating rods, a gear one fixedly connected to the right end of the front rotating rod, a motor fixedly connected to the front right side of the outer wall of the fixed base, a gear two fixedly connected to the output end of the motor, the outer wall of the gear two meshing with the outer wall of the gear one, and heating wires fixedly connected to the front and rear top sides of the fixed base, and rollers fixedly connected to the left and right sides of the outer wall of the fixed base. A fixing rod is fixedly connected, and a fixing column is fixedly connected to an adjacent side of the fixing rod. A drying drum is provided on the top of the outer wall of the fixing base. Fixing rings are fixedly connected to the left and right sides of the outer wall of the drying drum.

Baffles are rotatably connected to the left and right ends of the inner walls of the fixing rings. The middle parts of the two baffles are fixedly connected to the left and right ends of the outer walls of the fixing columns, respectively. A hot air fan is fixedly connected to the left side of the outer wall of the left baffle. A cleaning mechanism is provided on the outer walls of the two baffles. The cleaning mechanism is used to clean the inner wall of the drying drum.

[0006] As a further description of the above technical solution:

[0007] The cleaning mechanism includes two fixed buckets, which are respectively fixedly connected to the outer walls of the two baffles. Each of the two fixed buckets has a connecting post on its inner wall. Each of the two connecting posts has a threaded groove at an adjacent end, and the two threaded grooves are threadedly connected to the inner walls of the two connecting posts. Each of the two connecting posts has a connecting groove on an adjacent side of its outer wall, and each of the two connecting grooves has a scraper on an adjacent side of its inner wall. The left and right sides of the outer walls of the two scrapers are respectively engaged with the inner walls of the two connecting grooves.

[0010] As a further description of the above technical solution:

[0011] A mounting groove is provided on the right side of the outer wall of the cover plate, and a handle is fixedly connected to the inner wall of the mounting groove.

[0012] As a further description of the above technical solution:

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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] Reference Figure 1 , Figure 3 and Figure 5This utility model provides an embodiment of a drying device for raw materials used in the production of plastic woven bags. It includes a fixed base 1, with rotating rods 3 rotatably mounted on the front and rear sides of the top inner wall of the fixed base 1. Rollers 4 are fixedly connected to the left and right sides of the outer walls of the two rotating rods 3. The rotating rods 3 provide the rotation axis for the subsequently connected rollers 4. A gear 5 is fixedly connected to the right end of the front rotating rod 3. A motor 6 is fixedly connected to the front right side of the outer wall of the fixed base 1. A gear 7 is fixedly connected to the output end of the motor 6. The outer wall of gear 7 meshes with the outer wall of gear 5. When the motor 6 starts running, gear 5 rotates along with gear 7, thereby driving the connected front rotating rod 3 to rotate. Heating wires 8 are fixedly connected to the front and rear sides of the top of the fixed base 1. The heating wires 8 generate heat when energized, which can be directly transferred upwards to the bottom of the drying drum 11. Fixed rods 9 are fixedly connected to the left and right sides of the outer wall of the fixed base 1. A fixed column 10 is fixedly connected to one side, and a fixed rod 9 serves to connect and support the fixed column 10. A drying barrel 11 is provided on the top of the outer wall of the fixed base 1. Fixed rings 12 are fixedly connected to the left and right sides of the outer wall of the drying barrel 11. The outer walls of the two fixed rings 12 are rotatably connected to the outer walls of the two rollers 4 respectively. Baffles 13 are rotatably connected to the left and right ends of the inner walls of the fixed rings 12. When the drying barrel 11 is placed on the rollers 4 through the fixed rings 12, the baffles 13 can limit the excessive displacement of the fixed rings 12 in the horizontal direction. The middle parts of the two baffles 13 are fixedly connected to the left and right ends of the outer walls of the fixed column 10 respectively. A hot air blower 14 is fixedly connected to the left side of the outer wall of the left baffle 13. When the hot air blower 14 is working, it blows out hot air. The hot air flows inside the drying barrel 11, which can accelerate the flow speed of the air around the raw materials. A cleaning mechanism 2 is provided on the outer walls of the two baffles 13. The cleaning mechanism 2 is used to clean the inner wall of the drying barrel 11.

[0032] Specifically, the fixed base 1 serves as the basic support structure, and the rotating rod 3 on the top of its inner wall provides the rotation axis for the roller 4. The roller 4 can reduce the friction when the drying barrel 11 rotates, facilitating its rotation. The motor 6 serves as the power source, and the gear 7 connected to the output end meshes with the gear 5, driving the rotating rod 3 to rotate, thereby driving the drying barrel 11 to rotate. The heating wire 8 generates heat after being energized, which is transferred upward from the bottom of the drying barrel 11 to evaporate the moisture in the raw materials. The fixed rod 9 cooperates with the fixed column 10 to connect and support the baffle 13. The baffle 13 restricts the displacement of the fixed ring 12, ensuring the stability of the drying barrel 11. The hot air blower 14 blows out hot air, accelerating the airflow and working with the heating wire 8 to improve the drying efficiency. The drying barrel 11 is rotatably connected to the roller 4 through the fixed ring 12 to ensure its smooth rotation. The motor 6 provides power, the heating wire 8 and the hot air blower 14 provide heat, and the roller 4 assists the rotation of the drying barrel 11, so that the raw materials are evenly heated and dried during rotation, completing the drying operation of the raw materials for plastic woven bag production.

[0033] Reference Figure 1 , Figure 2 and Figure 4 The cleaning mechanism 2 includes two fixed barrels 201, which are fixedly connected to the outer walls of two baffles 13. The inner walls of the two fixed barrels 201 are provided with connecting columns 202. The function of the fixed barrels 201 is to provide a stable installation space for the internal connecting columns 202. The adjacent ends of the two connecting columns 202 are provided with threaded grooves 203. The two threaded grooves 203 are threadedly connected to the inner walls of the two connecting columns 202. By rotating the connecting columns 202, the relative distance between the two connecting columns 202 can be changed. The adjacent sides of the outer walls of the two connecting columns 202 are provided with connecting grooves 204. The adjacent sides of the inner walls of the two connecting grooves 204 are provided with scrapers 205. The left and right sides of the outer walls of the two scrapers 205 are respectively engaged with the inner walls of the two connecting grooves 204. The main function of the scrapers 205 is to clean the inner walls of the drying barrel 11.

[0034] Specifically, the two fixed barrels 201 are firmly fixed to the outer walls of the two baffles 13, so that the cleaning mechanism 2 can work synchronously with the operation of the drying barrel 11. The fixed barrels 201 provide stable support and operating space for the interior and can flexibly adjust the distance between the two connecting columns 202. When the drying barrel 11 needs to change the contact force between the scraper 205 and the inner wall of the drying barrel 11, it can be adjusted by utilizing the characteristics of the threaded connection. A connecting groove 204 is provided on the adjacent side of the outer wall of the connecting column 202 for installing the scraper 205. The scraper 205 is tightly engaged with the inner wall of the connecting groove 204. When the drying barrel 11 rotates under the drive of the roller 4, the scraper 205 will follow the connecting column 202 to rotate around the drying barrel 11. Its edge always remains in contact with the inner wall of the drying barrel 11, scraping off the raw materials adhering to the inner wall and ensuring the cleanliness of the inner wall of the drying barrel 11. This ensures that the drying operation can be carried out efficiently and continuously, providing a good internal environment for the drying of raw materials for plastic woven bag production.

[0035] Reference Figure 1 , Figure 2 and Figure 4A feed inlet 15 is provided on the outer wall of the right-side baffle 13. A cover plate 16 is provided on the right side of the outer wall of the feed inlet 15. Hinges 17 are fixedly connected to the top front and rear sides of the feed inlet 15. The outer walls of the two hinges 17 are rotatably connected to the top of the cover plate 16. The hinges 17, as connecting parts, give the cover plate 16 the ability to rotate around the top of the feed inlet 15. A mounting groove 18 is provided on the right side of the outer wall of the cover plate 16. A handle 19 is fixedly connected to the inner wall of the mounting groove 18. 19 provides a point of force application for the operator; the left side of the outer wall of the left side baffle 13 has a discharge port 20. The discharge port 20 is the outlet for the raw materials for producing plastic woven bags after drying to leave the drying barrel 11. The left side of the outer wall of the discharge port 20 is provided with a cover plate 21. The function of the hinge 22 is to allow the cover plate 21 to rotate flexibly around the top of the discharge port 20. The front and rear sides of the top of the discharge port 20 are fixedly connected with the hinge 22. The outer walls of the two hinges 22 are rotatably connected to the top of the cover plate 21.

[0036] Specifically, the feed inlet 15, which is fixedly connected to the outer wall of the right baffle 13, is the entrance for the raw materials for plastic woven bag production to enter the drying barrel 11. The cover plate 16, which is set on the right side of the outer wall of the feed inlet 15, is rotatably connected to the top of the feed inlet 15 by two hinges 17. The hinges 17 serve as connecting parts, allowing the cover plate 16 to rotate around the top of the feed inlet 15. This allows the operator to easily open the cover plate 16 when feeding is needed and close it after feeding to prevent heat loss during the drying process. The handle 19, which is fixedly connected in the mounting groove 18 on the right side of the outer wall of the cover plate 16, provides the operator with a force point to facilitate the opening and closing of the cover plate 16. The discharge port 20, which is fixedly connected to the left side of the outer wall of the left baffle 13, is the outlet for the raw materials for plastic woven bag production to leave the drying barrel 11 after drying. The cover plate 21, which is set on the left side of the outer wall of the discharge port 20, is also rotatably connected to the top of the discharge port 20 by two hinges 22. Hinge 22 uses the principle of rotation, which allows cover plate 21 to rotate flexibly around the top of discharge port 20, opening when discharging and closing when not discharging, ensuring normal operation of the equipment.

[0037] Reference Figure 1 , Figure 4 and Figure 5The outer wall of the cover plate 21 has an installation groove 23 on the left side. The inner wall of the installation groove 23 is fixedly connected to a handle 24. After drying, the operator needs to open the cover plate 21 to release the dried raw material. The handle 24 provides the operator with a convenient gripping part for applying force. The bottom of the outer wall of the motor 6 is provided with a fixing plate 25. As the power source of the whole device, the motor 6 needs to be stably installed and supported. The left side of the outer wall of the fixing plate 25 is fixedly connected to the front right side of the outer wall of the fixing seat 1. The bottom front and rear sides of the fixing plate 25 are fixedly connected to connecting pieces 26. The left side of the connecting piece 26 is threadedly connected to the right side of the outer wall of the fixing seat 1. The connecting piece 26 further enhances the stability of the connection between the fixing plate 25 and the fixing seat 1.

[0038] Specifically, the inner wall of mounting slot 23 is fixedly connected to handle 24. When the cover plate 21 needs to be opened or closed, the operator can apply force by gripping handle 24, using the lever principle to move the cover plate 21 more easily and conveniently, greatly improving the ease of operation. The left side of the outer wall of fixing plate 25 is fixedly connected to the front right side of the outer wall of fixing seat 1, ensuring that the motor 6 will not shift in the left or right direction during operation. At the same time, the connecting pieces 26 fixedly connected to the front and rear sides of the bottom of fixing plate 25 are threadedly connected to the right side of the outer wall of fixing seat 1. Through the threaded connection, on the one hand, the height of motor 6 can be flexibly adjusted according to actual needs during installation, and the tightening effect of the threads firmly fixes motor 6 to fixing seat 1. On the other hand, it is also easy to disassemble when maintenance or replacement of motor 6 is required. This multi-directional connection method ensures the stability of motor 6 during operation, enabling it to work continuously and efficiently.

[0039] Working principle: The motor 6 is started, and its output end drives the gear 7 to rotate. Since the gear 7 meshes with the gear 5, the front rotating rod 3 rotates, and the roller 4 connected to the rotating rod 3 rotates accordingly. The drying barrel 11 is placed on the roller 4 through the fixing ring 12 and starts to rotate under the drive of the roller 4. At the same time, the heating wires 8 on the front and rear sides of the top of the fixing seat 1 are energized to generate heat. The heat is transferred upward to the bottom of the drying barrel 11 to heat the raw materials in the barrel. The hot air blower 14 on the left baffle 13 blows out hot air. The hot air flows in the drying barrel 11, accelerating the air flow speed around the raw materials. Combined with the bottom heating, the drying efficiency is further improved. The fixing rod 9 connects to and supports the fixing column 10. The fixing column 10 is connected to the baffle 13. The baffle 13 restricts the horizontal displacement of the fixing ring 12 to ensure the stable rotation of the drying barrel 11 and realize the efficient drying treatment of the raw materials for plastic woven bag production.

[0040] Furthermore, during the cleaning process of the raw material drying device for plastic woven bags, the fixed bucket 201 is fixedly connected to the outer wall of the two baffles 13, providing a reliable installation space for the internal connecting column 202. The threaded groove 203 at one end of the connecting column 202 allows the relative distance between the two connecting columns 202 to be flexibly changed by rotating the connecting column 202, thereby adapting to drying buckets 11 of different sizes. The scraper 205 is engaged in the connecting groove 204 on the adjacent side of the outer wall of the connecting column 202. When the drying device is running... When the drying drum 11 rotates, the scraper 205 can clean its inner wall. Since the distance of the connecting column 202 is adjustable, the scraper 205 can fit tightly against the inner wall of the drying drum 11, effectively removing residual raw materials adhering to the drum wall. The fixed drum 201, the connecting column 202 and the scraper 205 work together. By adjusting the distance of the connecting column 202 to fit the drying drum 11, the scraper 205 cleans the drum wall during the rotation of the drying drum 11, ensuring the cleanliness of the inside of the drying device and improving drying efficiency and product quality.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
