Description

Technical Field

[0001] The present invention relates to the technical field of EPP material processing, and particularly to a feeding device for EPP material forming and processing. Background Art

[0002] EPP material, whose full name is expanded polypropylene, is a high-performance foam material with excellent properties such as light weight, high elasticity, impact resistance, temperature resistance, and environmental protection. Therefore, it is widely used in daily necessities, packaging, industry, agriculture, transportation, military industry, and aerospace industry.

[0003] Chinese Patent with publication number CN118205148A discloses a feeding device and its feeding method for EPP material forming and processing, which relates to the technical field of feeding devices. It includes a device housing. At the top end of the device housing, there is a storage hopper fixed for storing EPP materials. At the bottom of the side of the device housing away from the storage hopper, there is a feeding track. One end of the feeding track extends into the device housing to receive EPP materials. Inside the device housing and between the storage hopper and the feeding track, there is a feeding mechanism. The feeding mechanism is used to continuously and intermittently pour a fixed amount of EPP materials in the storage hopper into the feeding track. The feeding device can sequentially and equally take out the EPP materials in the discharge hopper, and then pour the taken-out EPP materials into the feeding track in sequence and send them out from the device housing for feeding in EPP material forming and processing. The amount of each feeding can be automatically controlled, and at the same time, automatic continuous feeding is realized, making the feeding device more flexible and convenient to use and more meeting the usage requirements. However, when the raw material plastic particles enter the extrusion molding equipment through the feeding hopper, they are prone to adhesion or slow flow. In severe cases, it will cause blockage, resulting in the raw materials being unable to enter the extrusion molding equipment, causing material breakage, and requiring manual dredging, which seriously affects the work efficiency.

Specific embodiments

[0028] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

[0029] Embodiment 1: Refer to Figures 1 - 3, a feeding device for the forming and processing of EPP materials, including a workbench 1. An extrusion molding device 6 is arranged on the top of the workbench 1, and a feeding hopper 3 is arranged on the top of the extrusion molding device 6. The outer wall above the feeding hopper 3 is rotatably connected with a rotating disk 16 through a bearing. One side outer wall of the top of the rotating disk 16 is fixedly connected with a folding plate 11. One end of the top of the folding plate 11 is hinged with a vertical plate 13, and one side outer wall of the vertical plate 13 is fixedly connected with a bearing plate 14. A stirring shaft 15 is arranged in the middle of the bearing plate 14, and a stirring motor 23 is arranged at the top end of the stirring shaft 15. A plurality of second stirring rods 18 are arranged at equal intervals on the outer wall above the stirring shaft 15, and a plurality of first stirring rods 17 with gradually decreasing lengths in sequence are arranged at equal intervals below the lowermost second stirring rod 18. A swinging mechanism is arranged on the outer wall of the stirring shaft 15, and a rotating mechanism is arranged on the outer wall of the rotating disk 16. After the raw materials enter the feeding hopper 3, the stirring motor 23 is started. The stirring motor 23 drives the connected stirring shaft 15 to rotate. The stirring shaft 15 can dredge and stir the raw materials in the feeding hopper 3 by rotating the plurality of second stirring rods 18 and the plurality of first stirring rods 17 with lengths gradually decreasing from top to bottom. When the stirring shaft 15 rotates, the swinging mechanism can make the stirring shaft 15 swing left and right, so as to increase the range of the first stirring rods 17 and the second stirring rods 18. Because the lengths of the first stirring rods 17 gradually decrease, the first stirring rods 17 can be prevented from colliding with the inner wall of the feeding hopper 3. And the rotating mechanism can make the rotating disk 16 rotate, so that the stirring shaft 15 moves around the outer wall of the feeding hopper 3 while swinging, and can fully dredge the raw materials in the feeding hopper 3, avoiding dead corners and greatly improving the feeding efficiency.

[0030] As a further scheme in the present invention, the swinging mechanism includes a mounting frame 21 and a worm 24. The worm 24 is fixedly connected to the outer wall of the stirring shaft 15. The mounting frame 21 is fixedly connected to the bottom outer wall of the vertical plate 13. A second rotating shaft 20 is rotatably connected inside the mounting frame 21. A worm gear 22 is fixedly connected to the middle outer wall of the second rotating shaft 20, and the worm gear 22 meshes with the worm 24. When the stirring shaft 15 rotates, it will drive the worm 24 to rotate. Because the worm 24 meshes with the worm gear 22 on the outer wall of the second rotating shaft 20, the second rotating shaft 20 can be made to rotate.

[0031] As a further scheme in the present invention, one end of the second rotating shaft 20 is fixedly connected with a second connecting plate 19, and one end of the second connecting plate 19 away from the second rotating shaft 20 is hinged with a first connecting plate 12. One end of the first connecting plate 12 away from the second connecting plate 19 is hinged on the outer wall of the folding plate 11. Because one end of the second rotating shaft 20 is fixedly connected with the first connecting plate 12, and the first connecting plate 12 and the folding plate 11 are hinged with the second connecting plate 19, when the stirring shaft 15 rotates, the stirring shaft 15 can be made to swing left and right.

[0032] As a further solution in the present invention, the rotating mechanism includes an L-shaped plate 2, which is fixedly connected to the outer wall of the top of the workbench 1, and a first rotating shaft 5 is rotatably connected to the top of the L-shaped plate 2. The bottom end of the first rotating shaft 5 is rotatably connected to the outer wall of the top of the workbench 1, and a third gear 9 is fixedly connected to the outer wall below the first rotating shaft 5.

[0033] As a further solution in the present invention, a driving motor 8 is arranged on one side of the first rotating shaft 5, and a second gear 7 is fixedly connected to the output shaft of the driving motor 8. The second gear 7 meshes with the third gear 9. A first gear 4 is fixedly connected to the top end of the first rotating shaft 5, and a fourth gear 10 meshes with one side of the first gear 4. The fourth gear 10 is fixedly connected to the outer wall of the rotating disc 16. The driving motor 8 rotates the second gear 7 at the end of its output shaft. Since the second gear 7 meshes with the third gear 9 on the first rotating shaft 5, when the second gear 7 rotates, the first rotating shaft 5 can be driven to rotate with the first gear 4. Also, since the first gear 4 meshes with the fourth gear 10 on the outer wall of the rotating disc 16, the rotating disc 16 can be driven to rotate with the folding plate 11, enabling the stirring shaft 15 to move around the feeding hopper 3.

[0034] Working principle: When the raw materials enter the feeding hopper 3, the stirring motor 23 starts, and the stirring motor 23 drives the connected stirring shaft 15 to rotate. The stirring shaft 15 can dredge and stir the raw materials in the feeding hopper 3 by rotating a plurality of second stirring rods 18 and a plurality of first stirring rods 17 with lengths gradually decreasing from top to bottom. When the stirring shaft 15 rotates, it will drive the worm 24 to rotate. Since the worm 24 meshes with the worm gear 22 on the outer wall of the second rotating shaft 20, the second rotating shaft 20 can be driven to rotate. Since one end of the second rotating shaft 20 is fixedly connected to a first connecting plate 12, and a second connecting plate 19 is hinged between the first connecting plate 12 and the folding plate 11, when the stirring shaft 15 rotates, the stirring shaft 15 can swing left and right while rotating, thereby increasing the stirring range of the first stirring rods 17 and the second stirring rods 18. Since the lengths of the first stirring rods 17 gradually decrease, the first stirring rods 17 can be prevented from colliding with the inner wall of the feeding hopper 3. Then, the driving motor 8 rotates the second gear 7 at the end of its output shaft. Since the second gear 7 meshes with the third gear 9 on the first rotating shaft 5, when the second gear 7 rotates, the first rotating shaft 5 can be driven to rotate with the first gear 4. Also, since the first gear 4 meshes with the fourth gear 10 on the outer wall of the rotating disc 16, the rotating disc 16 can be driven to rotate with the folding plate 11, causing the stirring shaft 15 to move around the feeding hopper 3. Thus, the stirring shaft 15 moves around the outer wall of the feeding hopper 3 while swinging, which can fully dredge the raw materials in the feeding hopper 3, avoid dead corners, and greatly improve the feeding efficiency.

[0035] Example 2: Refer to Figures 1 - 5, a feeding device for the forming and processing of EPP materials. Compared with Embodiment 1, on the basis of Embodiment 1, a first bevel gear 26 is fixedly connected to the outer wall above the stirring shaft 15, and a placing cover 29 is sleeved on the outer wall of the first bevel gear 26. The placing cover 29 is hermetically and rotatably connected to the outer wall of the stirring shaft 15, and two connecting columns 30 are symmetrically and fixedly connected between the placing cover 29 and the bottom outer wall of the bearing plate 14. A plurality of fixing plates 33 are fixedly connected at equal intervals inside the placing cover 29.

[0036] As a further scheme in the present invention, a third rotating shaft 27 is rotatably connected to the middle of each fixing plate 33, and a second bevel gear 31 is fixedly connected to one end of each third rotating shaft 27. The second bevel gears 31 are all meshed with the first bevel gear 26. The other ends of the third rotating shafts 27 are all fixedly connected with a plurality of fan blades 32. A plurality of exhaust holes 28 are arranged on the outer wall of the placing cover 29. When the stirring shaft 15 rotates, it will synchronously drive the rotation of the first bevel gear 26. Since the second bevel gears 31 on each third rotating shaft 27 are all meshed with the first bevel gear 26, when the first bevel gear 26 rotates, it can drive the rotation of each third rotating shaft 27, so that each third rotating shaft 27 drives the corresponding plurality of fan blades 32 to rotate, and a huge suction force can be generated.

[0037] As a further scheme in the present invention, an air extraction channel 25 is arranged inside the stirring shaft 15, and a plurality of air inlet holes 35 are arranged at equal intervals below the air extraction channel 25, and a plurality of air extraction holes 34 are arranged at equal intervals above the air extraction channel 25. The air extraction holes 34 are located above the first bevel gear 26 and in the placing cover 29. Thus, the gas flowing between the raw materials at the lower end of the feeding hopper 3 can be sucked into the air extraction channel 25 through the plurality of air inlet holes 35, then enter the placing cover 29 through the plurality of air extraction holes 34, and finally be discharged through the plurality of exhaust holes 28, avoiding the gas flowing through the raw materials during stirring from entering the extrusion molding device 6, resulting in bubbles and affecting the product quality.

[0038] Working principle: When the stirring shaft 15 rotates, it will synchronously drive the rotation of the first bevel gear 26. Since the second bevel gears 31 on each third rotating shaft 27 are all meshed with the first bevel gear 26, when the first bevel gear 26 rotates, it can drive the rotation of each third rotating shaft 27, so that each third rotating shaft 27 drives the corresponding plurality of fan blades 32 to rotate, and a huge suction force can be generated. Thus, the gas flowing between the raw materials at the lower end of the feeding hopper 3 can be sucked into the air extraction channel 25 through the plurality of air inlet holes 35, then enter the placing cover 29 through the plurality of air extraction holes 34, and finally be discharged through the plurality of exhaust holes 28, avoiding the gas flowing through the raw materials during stirring from entering the extrusion molding device 6, resulting in bubbles and affecting the product quality.

[0039] Embodiment 3: Refer to Figures 1 - 7, a feeding device for the forming process of EPP materials. Compared with Embodiment 2, on the basis of Embodiment 2, a fixing column 37 is provided on the outer wall of the top of the extrusion molding device 6, and a knocking plate 38 is rotatably connected to the top of the fixing column 37. A hook spring 39 is provided between the outer wall of one side of the bottom of the knocking plate 38 and the outer wall of the top of the extrusion molding device 6. A plurality of driving plates 36 are fixedly connected to the outer wall of the first rotating shaft 5 at equal distances, and the driving plates 36 and the knocking plate 38 are on the same horizontal plane. When the first rotating shaft 5 rotates, it will drive a plurality of driving plates 36 to do circular motion. During this process, a plurality of driving plates 36 will intermittently contact one end of the knocking plate 38. When the driving plate 36 contacts the knocking plate 38, a force is applied to it to make it rotate. At this time, the end of the knocking plate 38 in contact with the feeding hopper 3 will stretch the hook spring 39 and move away from the feeding hopper 3. When the driving plate 36 is separated from the knocking plate 38, under the action of the resilience of the hook spring 39, the knocking plate 38 will quickly reset and knock on the lower end of the feeding hopper 3, causing the raw materials at this position inside the feeding hopper 3 to vibrate, preventing the raw materials from accumulating at the lower end of the feeding hopper 3 and avoiding the situation of secondary blockage caused by the increase in the flow resistance of the raw materials.

[0040] Working principle: When the first rotating shaft 5 rotates, it will drive a plurality of driving plates 36 to do circular motion. During this process, a plurality of driving plates 36 will intermittently contact one end of the knocking plate 38. When the driving plate 36 contacts the knocking plate 38, a force is applied to it to make it rotate. At this time, the end of the knocking plate 38 in contact with the feeding hopper 3 will stretch the hook spring 39 and move away from the feeding hopper 3. When the driving plate 36 is separated from the knocking plate 38, under the action of the resilience of the hook spring 39, the knocking plate 38 will quickly reset and knock on the lower end of the feeding hopper 3, causing the raw materials at this position inside the feeding hopper 3 to vibrate, preventing the raw materials from accumulating at the lower end of the feeding hopper 3 and avoiding the situation of secondary blockage caused by the increase in the flow resistance of the raw materials.
